Incidence and Mortality
Estimated new cases and deaths from testicular cancer in the United States in 2024:[
Testicular cancer is a highly treatable, usually curable cancer that most often develops in young and middle-aged men. Most testicular cancers are germ cell tumors. For treatment planning, germ cell tumors are broadly divided into seminomas and nonseminomas because they have different prognostic and treatment algorithms. For patients with seminomas (all stages combined), the cure rate exceeds 90%. For patients with low-stage seminomas or nonseminomas, the cure rate approaches 100%.[
Risk Factors
Risk factors for testicular cancer include the following:[
Surgical correction of an undescended testis (orchiopexy) before puberty appears to lower the risk of testicular cancer, but this is not certain.[
Histopathology
Types of testicular germ cell tumors: Seminomas versus nonseminomas
The five histopathological subtypes of testicular germ cell tumors include the following:
Tumors that are 100% seminoma are considered seminomas. All other tumors, including those that have a mixture of seminoma and nonseminoma components, are considered and should be managed as nonseminomas. Most nonseminomas consist of a mixture of the different germ cell tumor subtypes. Tumors that appear to have a seminoma histology but are accompanied by an elevated serum level of alpha-fetoprotein (AFP) should be treated as nonseminomas because seminomas do not produce AFP.
Prognosis and Staging
Serum tumor markers and testis cancer: AFP, beta-hCG, and LDH
Alpha-fetoprotein (AFP), beta-human chorionic gonadotropin (beta-hCG), and lactase dehydrogenase (LDH) play an important role as serum tumor markers in the staging and monitoring of germ cell tumors and should be measured prior to removing the involved testicle.[
AFP: Elevation of serum AFP is seen in 40% to 60% of men with nonseminomas. Seminomas do not produce AFP. Men who have an elevated serum AFP have a mixed germ cell tumor (i.e., nonseminomatous germ cell tumors [NSGCT]) even if the pathology shows a pure seminoma—unless there is a more persuasive explanation for the elevated AFP, such as liver disease.
Beta-hCG: Elevation of beta-hCG is found in approximately 14% of patients with stage I pure seminomas before orchiectomy and in about one-half of patients with metastatic seminomas.[
Significant and unambiguously rising levels of AFP and/or beta-hCG signal relapsed germ cell tumor in most cases and are an indication for treatment even in the absence of radiological evidence of metastatic disease. Nonetheless, tumor marker elevations need to be interpreted with caution. For example, false-positive beta-hCG levels can result from cross reactivity of the assay with luteinizing hormone in which case an intramuscular injection of testosterone should result in normalization of beta-hCG values. There are also clinical reports of marijuana use resulting in elevations of serum beta-hCG and some experts recommend querying patients about drug use and retesting beta-hCG levels after a period of abstinence from marijuana use. Similarly, AFP is chronically mildly elevated in some individuals for unclear reasons and can be substantially elevated by liver disease.
LDH: Seminomas and nonseminomas alike may result in elevated LDH but such values are of unclear prognostic significance because LDH may be elevated in many conditions unrelated to cancer. A study evaluated the utility of LDH in 499 patients with a testicular germ cell tumor who were undergoing surveillance after orchiectomy or treatment of stage II or III disease. It found that 7.7% of patients had elevated LDH unrelated to cancer, while only 1.4% of patients had cancer-related increases in LDH.[
A second study reported that among 494 patients with stage I germ cell tumors who subsequently had a relapse, 125 had an elevated LDH at the time of relapse. Of these 125 patients, all had other evidence of relapse: 112 had a concurrent rise in AFP and/or beta-hCG, one had computed tomography (CT) evidence of relapse before the elevation in LDH, one had palpable disease on examination, and one complained of back pain that led to imaging that revealed retroperitoneal relapse.[
Staging and risk stratification
There are two major prognostic models for testicular cancer: staging[
For men with disseminated seminomas, the main adverse prognostic variable is the presence of metastases to organs other than the lungs (e.g., bone, liver, or brain). For men with disseminated nonseminomas, the following variables are independently associated with poor prognosis:
Nonetheless, even patients with widespread metastases at presentation, including those with brain metastases, may have curable disease and should be treated with this intent.[
Radical inguinal orchiectomy with initial high ligation of the spermatic cord is the procedure of choice in diagnosing and treating a malignant testicular mass.[
Diagnostics
Evaluation of the retroperitoneal lymph nodes, usually by CT scan, is an important aspect of staging and treatment planning in adults with testicular cancer.[
Follow-Up and Survivorship
Patients who have been cured of testicular cancer have approximately a 2% cumulative risk of developing cancer in the opposite testicle during the 15 years after initial diagnosis.[
Men with HIV are reported to be at increased risk of developing testicular seminomas.[
Because most patients with testicular cancer who receive adjuvant chemotherapy or radiation therapy are curable, it is necessary to be aware of possible long-term effects of the various treatment modalities, such as the following:
Radiation therapy, used to treat pure seminomatous testicular cancers, can cause fertility problems because of radiation scatter to the remaining testicle during radiation therapy to retroperitoneal lymph nodes (as evidenced in the SWOG-8711 trial, for example).[
Although acute pulmonary toxic effects may occur with bleomycin, they are rarely fatal at total cumulative doses of less than 400 units. Because life-threatening pulmonary toxic effects can occur, the drug should be discontinued if early signs of pulmonary toxicity develop. Although decreases in pulmonary function are frequent, they are rarely symptomatic and are reversible after chemotherapy ends. Survivors of testis cancer who were treated with chemotherapy have been reported to be at increased risk of death from respiratory diseases, but it is unknown whether this finding is related to bleomycin exposure.[
Radiation therapy, often used in the management of pure seminomatous germ cell cancers, has been linked to the development of secondary cancers, especially solid tumors in the radiation portal, usually after a latency period of a decade or more.[
Other risk factors
Cardiovascular disease in testicular cancer survivors
Men with testicular cancer who have been treated with radiation therapy and/or chemotherapy are at increased risk of cardiovascular events.[
In a retrospective series of 992 patients treated for testicular cancer between 1982 and 1992, cardiac events were increased approximately 2.5-fold in patients treated with radiation therapy and/or chemotherapy, compared with those who underwent surveillance for a median of 10.2 years. The actuarial risks of cardiac events were 7.2% for patients who received radiation therapy (92% of whom did not receive mediastinal radiation therapy), 3.4% for patients who received chemotherapy (primarily platinum-based), 4.1% for patients who received combined therapy, and 1.4% for patients who underwent surveillance management after 10 years of follow-up.[
A population-based retrospective study of 2,339 testicular cancer survivors in the Netherlands, treated between 1965 and 1995 and followed for a median of 18.4 years, found that the overall incidence of coronary heart disease (i.e., myocardial infarction and/or angina pectoris) was increased 1.17 times (95% confidence interval [CI], 1.04–1.31) compared with the general population.[
Although testicular cancer is highly curable, all newly diagnosed patients are appropriate candidates for clinical trials designed to decrease morbidity of treatment while further improving cure rates.

In addition to the clinical stage definitions, surgical stage may be designated based on the results of surgical removal and microscopic examination of tissue.
Stage 0
Stage 0 testicular cancer is testicular intraepithelial neoplasia (TIN), also referred to as intratubular germ cell neoplasia (ITGCN). TIN is analogous to carcinoma in situ. In most cases, TIN is diagnosed as a result of an orchiectomy that was performed to remove an invasive germ cell tumor (pT1–T4); generally, TIN has already been removed from the body at the time of diagnosis and requires no treatment. A more challenging situation arises if a biopsy is performed of the contralateral testis and TIN is discovered. Because of the low incidence and low mortality rates associated with contralateral germ cell tumors, such biopsies are performed rarely in the United States. Therefore, TIN is almost never diagnosed in testicles that do not also have an invasive tumor. Consequently, a treatment decision about TIN in stage 0 testicular cancer is rarely faced in the United States. Treatment options for ITGCN include radiation therapy, surveillance, and orchiectomy.
Stage I
Stage I testicular cancer is limited to the testis. Invasion of the scrotal wall by tumor or interruption of the scrotal wall by previous surgery does not change the stage but does increase the risk of spread to the inguinal lymph nodes, and this must be considered in treatment and follow-up. Invasion of the epididymis tunica albuginea and/or the rete testis does not change the stage. Invasion of the tunica vaginalis or lymphovascular invasion signifies a T2 tumor, while invasion of the spermatic cord signifies a T3 tumor, and invasion of the scrotum signifies a T4. Increases in T stage are associated with increased risk of occult metastatic disease and recurrence. Men with stage I disease who have persistently elevated serum tumor markers after orchiectomy are staged as IS, but stage IS nonseminomas are treated as stage III. Elevated serum tumor markers in stage I or II seminoma are of unclear significance except that a persistently elevated or rising beta-hCG usually indicates metastatic disease.
Stage II
Stage II testicular cancer involves the testis and the retroperitoneal or periaortic lymph nodes usually in the region of the kidney. Retroperitoneal involvement should be further characterized by the number of nodes involved and the size of involved nodes. The risk of recurrence is increased if more than five nodes are involved or if the size of one or more involved nodes is more than 2 cm. Bulky stage II disease (stage IIC) describes patients with extensive retroperitoneal nodes (>5 cm), which portends a less favorable prognosis.
Stage III
Stage III disease has spread beyond the retroperitoneal nodes based on physical examination, imaging studies, and/or blood tests (i.e., patients with retroperitoneal adenopathy and highly elevated serum tumor markers are stage III). Stage III can be further stratified based on the location of metastasis and the degree of elevation of serum tumor markers. In the favorable group (IIIA), metastases are limited to lymph nodes and lung, and serum tumor markers are no more than mildly elevated. Stage IIIB patients have moderately elevated tumor markers, while stage IIIC patients have highly elevated markers and/or metastases to liver, bone, brain, or some organ other than the lungs. These subclassifications of stage III correspond to the International Germ Cell Consensus Classification system for disseminated germ cell tumors.[

Testicular cancer is broadly divided into seminomas and nonseminomas for treatment planning. Seminomatous types of testicular cancer are more sensitive to radiation therapy and chemotherapy and are less prone to distant metastases than nonseminomatous types. Nonseminomas may include teratomatous elements, which tend to be resistant to chemotherapy and often require surgery for cure. By definition, pure seminomas do not contain elements of teratoma. Therefore, surgery plays a larger role in the management of nonseminomas than in the management of seminomas. Nonseminomatous testicular tumors include the following:
An international germ cell tumor prognostic classification has been developed based on a retrospective analysis of 5,202 patients with metastatic nonseminomatous and 660 patients with metastatic seminomatous germ cell tumors.[
A meta-analysis of treatment outcomes for patients with advanced nonseminoma suggested that 5-year survival rates have improved for those patients with a poor prognosis during the period of 1989 to 2004.[
Good Prognosis
Nonseminoma:
A total of 56% to 61% of nonseminomas are good prognosis. The 5-year progression-free survival (PFS) rate is 89%; the 5-year survival rate is 92%–94%. |
Seminoma:
A total of 90% of seminomas are good prognosis. The 5-year PFS rate is 82%; the 5-year survival rate is 86%. |
Intermediate Prognosis
Nonseminoma:
A total of 13% to 28% of nonseminomas are intermediate prognosis. The 5-year PFS rate is 75%; the 5-year survival rate is 80%–83%. |
Seminoma:
A total of 10% of seminomas are intermediate prognosis. The 5-year PFS rate is 67%; the 5-year survival rate is 72%. |
Poor Prognosis
Nonseminoma:
A total of 16% to 26% of nonseminomas are poor prognosis. The 5-year PFS rate is 41%; the 5-year survival rate is 71%. |

Among men diagnosed with an invasive testicular germ cell tumor (stages I–III), 0.5% to 1.0% will present with tumors in both testes, and another 1% to 2% will develop a subsequent invasive germ cell tumor in the contralateral testis.[
If biopsies of the contralateral testis are performed in men with testicular cancer, 4% to 8% of men will be found to have contralateral TIN. The treatment is typically radiation therapy (18 Gy–20 Gy), surveillance, or orchiectomy. Men undergoing radiation therapy or orchiectomy will subsequently be sterile. Men undergoing orchiectomy will also be hypogonadal as will many men undergoing radiation therapy.[

Stage I Seminoma
Patients with stage I seminomas have a cure rate that approaches 100%, regardless of whether postorchiectomy adjuvant therapy is given.
Treatment options:
Results of multiple clinical series, including more than 1,200 patients with stage I seminoma managed by postorchiectomy surveillance, have been reported.[
Treatment options when surveillance is not chosen:
The surveillance-after-orchiectomy treatment option is associated with a cure rate that approaches 100%. Relapses requiring additional therapy occur in about 15% of patients who are treated with the surveillance treatment option. The surveillance strategy avoids the need for radiation or chemotherapy in most patients. However, some patients are uncomfortable with surveillance only and wish to minimize the risk of relapse. For such patients, one of the following options may be used; however, there is controversy about which strategy is preferred:[
One of the following two treatment fields is typically used: a para-aortic strip covering the retroperitoneal nodes or a dog-leg field that includes the ipsilateral iliac lymph nodes as well as the retroperitoneum. The dose ranges from 20 Gy to 26 Gy. Relapse rates and toxic effects were studied in a randomized comparison (MRC-TE10) of para-aortic radiation therapy alone versus para-aortic radiation therapy with an added ipsilateral iliac lymph node field.[
In a randomized trial (MRC-TE18), a radiation dose of 20 Gy over 10 daily fractions was clinically equivalent to 30 Gy over 15 fractions after a median follow-up of 7 years in both RFS and OS. Patients reported that lethargy and their ability to perform normal work were better in the lower-dose regimen.[
Radiation therapy for clinical stage I testicular seminoma is no longer favored because of evidence that this treatment is associated with an increased risk of secondary malignancies and an increased risk of death from secondary malignancies. An analysis of data from the population-based Surveillance, Epidemiology, and End Results (SEER) Program registries in the United States between the years 1973 and 2001 indicated that among 7,179 men receiving radiation therapy for stage I seminoma, 246 had an increased risk of death from secondary cancers compared with the general population (standardized mortality ratio, 1.89; 95% CI, 1.67–2.14).[
In a large, randomized, controlled, noninferiority trial (MRC-TE19 [NCT00003014]), 1,477 men with stage I seminomas were assigned to undergo para-aortic (or dog-leg field, if clinically indicated) radiation therapy or to receive a single dose of carboplatin (concentration-versus-time or area-under-the-curve [AUC] × 7) after radical inguinal orchiectomy study participants were followed up for a median of 6.5 years.[
Phase II studies, including several with more than 4 years median follow-up, have consistently reported lower relapse rates (0%–3.3%) when two doses of carboplatin were administered either 3 or 4 weeks apart and dosed either at 400 mg/m2 or at an AUC of 7.[
Stage I Nonseminoma
Stage I nonseminoma is highly curable (>99%). Orchiectomy alone will cure about 70% of patients, but the remaining 30% will relapse and require additional treatment. The relapses are highly curable, and postorchiectomy surveillance is a standard treatment option, but some physicians and patients prefer to reduce the risk of relapse by having the patient undergo either a retroperitoneal lymph node dissection (RPLND) or one or two cycles of chemotherapy. Each of these three approaches has unique advantages and disadvantages, and none has been shown to result in longer survival or superior quality of life.
Treatment options:
Typically, patients are seen monthly during the first year, every 2 months during the second year, every 3 months during the third year, every 4 months during the fourth year, every 6 months during the fifth year, and annually for the subsequent 5 years.[
A randomized controlled trial (MRC-TE08 [NCT00003420]) compared a schedule that used only two scans at 3 months and 12 months with a schedule that used five scans at 3, 6, 9, 12, and 24 months.[
The need for long-term follow-up has not been adequately investigated. Surveillance series with long follow-up times have reported that fewer than 1% of clinical stage I patients relapse after 5 years.[
The option of a radical inguinal orchiectomy followed by a regular and frequent surveillance schedule should be considered only if:
A nerve-sparing RPLND that preserves ejaculation in virtually every patient has been described in clinical stage I patients and appears to be as effective as the standard RPLND.[
Men undergoing RPLND, who are found to have pathological stage I disease, have a roughly 10% risk of relapsing subsequently, whereas men with pathological stage II disease (i.e., those who are found to have lymph node metastases at RPLND) have as much as a 50% risk of relapse without further treatment.[
In patients with pathological stage I disease after RPLND, the presence of lymphatic or venous invasion or a predominance of embryonal carcinoma in the primary tumor appears to predict for relapse.[
Among pathological stage II patients, the relapse rate was 32% among men with embryonal carcinoma-predominant tumors compared with 15.6% in the other stage II patients. The risk of metastatic disease (i.e., either pathological stage II disease or relapsed pathological stage I disease) in men with tumors showing a predominance of embryonal carcinoma plus lymphovascular invasion was 62% compared with 16% in men with neither risk factor.
These data have shown that high-risk patients undergoing RPLND have a substantial risk of subsequently receiving chemotherapy. Data from one institution have shown that about one-half of men with stage I pure embryonal carcinoma undergoing RPLND will subsequently receive cisplatin-based chemotherapy.[
Retroperitoneal dissection of lymph nodes is not helpful in the management of children, and potential morbidity of the surgery is not justified by the information obtained.[
A randomized controlled trial compared a single cycle of BEP chemotherapy with RPLND in 382 patients. The 2-year recurrence-free survival rates were 99.5% with chemotherapy versus 91.9% with RPLND (absolute difference, 7.6%; 95% CI, 3.1%–12.1%). There were no treatment-related or cancer-specific deaths in either arm of the study.[
A Swedish and Norwegian study reported results of a risk-adapted therapy protocol in which patients with nonseminomas with lymphovascular invasion underwent postorchiectomy chemotherapy with one or two cycles of BEP chemotherapy, while those without lymphovascular invasion underwent either surveillance or a single cycle of BEP.[
Several phase II studies and case series reporting results after two cycles of BEP in patients with intermediate- or high-risk disease have identified relapse rates ranging from 0% to 4% (average, 2.4%).[
There is no consensus about the optimal management of men with stage I nonseminomas, but each of the three strategies above produces a disease-specific survival rate of about 99%. Some clinicians have advocated a risk-adapted approach such that patients with low-risk disease undergo surveillance, while others undergo either RPLND or chemotherapy. The goal of this approach is to minimize the side effects of treatment, but risk-adapted therapy has never been demonstrated to result in better outcomes. Some experts prefer a surveillance strategy generally so as to minimize unnecessary treatment. Others prefer RPLND to obtain more accurate staging, to reduce the risk of needing chemotherapy (and, therefore, chemotherapy's side effects and toxicity) and to, theoretically, reduce the risk of late relapse. At the same time, many experts reject RPLND as insufficiently effective at lowering relapse rates and prefer chemotherapy. Surveillance and chemotherapy have been tested at the regional and national level with excellent results, however, the limited data concerning RPLND in patients with regional disease have shown higher than expected in-field relapse rates but no deaths.[
With regard to risk stratification, data suggest that relapse rates are higher in patients with histological evidence of lymphatic or venous invasion or a predominance of embryonal carcinoma.[

Stage II Seminoma
Stage II seminoma is divided into bulky and nonbulky disease for treatment planning and expression of prognosis. Bulky disease is generally defined as tumors larger than 5 cm on a computed tomography (CT) scan (i.e., stage IIC disease). Nonbulky disease can be further subdivided into stage IIA, meaning no lymph node mass larger than 2 cm, and stage IIB, meaning a lymph node mass between 2 cm and 5 cm.
Nonbulky stage II disease has a cure rate of about 90% to 95% with radiation therapy alone at doses of 30 Gy to 36 Gy.[
Results for patients with stage IIC disease have been less favorable. For example, one institution reported that among patients with stage IIC disease, 9 of 16 (56%) had a relapse following radiation therapy, compared with only 1 of 23 patients (4%) treated with chemotherapy.[
Residual radiological abnormalities are common at the completion of chemotherapy. Many abnormalities gradually regress during a period of months. Some clinicians advocate empiric attempts to resect residual masses 3 cm or larger, while others advocate close surveillance, with intervention only if the residual mass increases in size. Postchemotherapy radiation therapy is no longer favored, in part because of a retrospective study of a consecutive series of 174 patients with seminoma and postchemotherapy residual disease seen at ten treatment centers. The study reported that empiric radiation was not associated with any medically significant improvement in progression-free survival after completion of platinum-based combination chemotherapy.[
In some series, surgical resection of specific masses has yielded a significant number of patients with residual seminoma who require additional therapy.[
A more recent approach has been to obtain a fluorine F 18-fludeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) scan following chemotherapy. A study of 56 patients reported that positron emission tomography (PET) scans correctly identified eight of ten patients with residual seminoma with no false positives among the 46 patients with benign masses.[

Treatment options for patients with bulky tumors:
Stage II Nonseminoma
Stage II nonseminoma is highly curable (>95%). Men with stage II disease and persistently elevated serum tumor markers are generally treated as having stage III disease and receive chemotherapy. For men with normal markers after orchiectomy, nonseminomas are divided into stages IIA, IIB, and IIC for treatment purposes. In general, stage IIA patients undergo RPLND to confirm the staging. As many as 40% of clinical stage IIA patients will have benign findings at RPLND and will be restaged as having pathological stage I disease.[
In contrast, patients with stage IIB and IIC nonseminoma are usually treated with systemic chemotherapy for disseminated disease because these patients have a higher relapse rate after RPLND. One study reported that by limiting RPLND to patients with earlier stage II disease and normal serum tumor markers, 5-year RFS rates increased from 78% to 100% after RPLND, while RFS did not change significantly among stage II patients receiving chemotherapy (100% vs. 98%).[
Treatment options:
This option of surgery and careful follow-up, reserving chemotherapy for relapse, is particularly attractive for patients who have pathological stage I or IIA disease (fewer than six positive nodes at RPLND, none of which are larger than 2 cm in diameter). Such patients appear to have a relapse rate of about 10% if followed without chemotherapy, and most are curable with standard chemotherapy if their disease relapses.[
This option of RPLND plus adjuvant chemotherapy applies to patients who have pathologically confirmed lymph node metastases as a result of RPLND and is most attractive for patients with pathological stage IIB or IIC disease. The results of a large study comparing the first treatment option with the second treatment option were published.[
This option is useful for patients with elevated serum tumor markers and/or clinical stage IIB or IIC disease. The combination of chemotherapy plus resection of residual masses in these patients results in cure in more than 95% of patients.[
Chemotherapy regimens include:
A randomized study has shown that bleomycin is an essential component of the BEP regimen when only three courses are administered.[
Other regimens that appear to produce similar survival outcomes but are no longer considered standard include:
In a randomized comparison of PVB versus BEP, equivalent anticancer activity was seen but with less toxic effects with the use of BEP.[
If these patients do not achieve a complete response with chemotherapy, surgical removal of residual masses should be performed. The timing of such surgery requires clinical judgment but would occur most often after three or four cycles of combination chemotherapy and normalization or stabilization of serum markers. The presence of persistently elevated markers is not a contraindication to resection of residual masses, but patients with rising markers at the end of chemotherapy are generally treated with salvage chemotherapy. Despite numerous studies, no sufficiently accurate predictors of the histology of residual masses have been validated. Therefore, the standard of care is to resect all residual masses apparent on scans in patients who have normal or stable markers after responding to chemotherapy. The presence of persistent nonseminomatous germ-cell malignant elements in the resected specimen is a poor prognostic sign and is often a trigger for additional chemotherapy. However, men with only microscopic residual cancer have a much more favorable prognosis than men with more substantial residual disease.[
In some cases, chemotherapy is initiated before orchiectomy because of life-threatening metastatic disease. When this is done, orchiectomy after initiation or completion of chemotherapy is advisable to remove the primary tumor. There is a higher incidence (approximately 50%) of residual cancer in the testicle than in remaining radiographically detectable retroperitoneal masses after platinum-based chemotherapy.[

Stage III seminoma and nonseminomas are usually curable but have different criteria for estimating prognosis.
Patients with disseminated seminomas can be divided into good-risk and intermediate-risk groups based on whether nonpulmonary visceral metastases are present. Patients with good-risk disease (i.e., those with metastases only to lymph nodes and/or lungs) have 5-year progression-free survival (PFS) and overall survival (OS) rates of 82% and 86%, respectively. Patients with intermediate-risk seminoma have 5-year PFS and OS rates of 67% and 72%, respectively.[
Patients with disseminated nonseminomas can be divided into good-, intermediate-, and poor-risk groups based on whether nonpulmonary visceral metastases are present, the site of the primary tumor (i.e., mediastinal vs. either gonadal or retroperitoneal), and the level of serum tumor markers.[
In the 1997 analysis that established these risk groups, the 5-year OS rates were 92%, 80% and 48% in the good-, intermediate-, and poor-risk groups, respectively. The PFS rates were 89%, 75% and 41% in the good-, intermediate-, and poor-risk groups, respectively. However, a 2006 pooled analysis of chemotherapy trials reported improved outcomes compared with the 1997 paper: survival rates in the good-, intermediate-, and poor-risk groups were 94%, 83%, and 71%, respectively.[
Clinical Trials of Chemotherapy for Disseminated Testis and Extragonadal Germ Cell Tumors
Four cycles of bleomycin, etoposide, and cisplatin (BEP) chemotherapy as a standard-of-care treatment option for patients with metastatic testicular germ cell tumors was established by a randomized trial showing that it produced similar outcomes with fewer toxic effects in comparison with cisplatin, vinblastine, and bleomycin (PVB).[
Numerous attempts have been made to develop a regimen superior to BEP for men with poor-prognosis germ cell tumors but none have been successful. Most recently, four cycles of BEP was compared with two cycles of BEP followed by two cycles of high-dose cyclophosphamide, etoposide, and carboplatin, but there was no difference in survival between the two arms.[
For patients with good-risk disease, the goal of clinical trials has been to minimize the toxic effects of treatment without sacrificing the therapeutic effectiveness. As noted above, no difference in outcome was seen when comparing three versus four cycles of BEP chemotherapy. However, attempts to eliminate bleomycin produced more ambiguous and usually disappointing results. A randomized controlled trial comparing three cycles of BEP with three cycles of etoposide and cisplatin (EP) reported lower OS rates (95% vs. 86%, P = .01) in the EP arm.[
Special Considerations During Chemotherapy
In most patients, an orchiectomy is performed before starting chemotherapy. If the diagnosis has been made by biopsy of a metastatic site (or on the basis of highly elevated serum tumor markers and radiological imaging consistent with an advanced-stage germ cell tumor) and chemotherapy has been initiated, subsequent orchiectomy is generally performed because chemotherapy may not eradicate the primary tumor. Case reports illustrate that viable tumor has been found on postchemotherapy orchiectomy despite complete response of metastatic lesions.[
Some retrospective data suggest that the experience of the treating institution may impact the outcome of patients with stage III nonseminoma. Data from 380 patients treated from 1990 to 1994 on the same study protocol at 49 institutions in the European Organisation for Research and Treatment of Cancer and the Medical Research Council were analyzed.[
Similarly, a population-based study of testis cancer in Japan in the 1990s reported a significant association between survival and the number of testis cancer patients treated. The relative 5-year survival rate was 98.8% at high-volume hospitals compared with 79.7% at low-volume hospitals. After adjusting for stage and age, the hazard ratio for death in a high-volume hospital was 0.11 (95% CI, 0.025–0.495).[
Many patients with poor-risk, nonseminomatous testicular germ cell tumors who have a serum beta-human chorionic gonadotropin (beta-hCG) level higher than 50,000 IU/mL at the initiation of cisplatin-based therapy (BEP or PVB) will still have an elevated beta-hCG level at the completion of therapy, showing an initial rapid decrease in beta-hCG followed by a plateau.[
Residual Masses After Chemotherapy in Men With Seminomas
Residual radiological abnormalities are common at the completion of chemotherapy. Such masses are not treated unless they grow or are histopathologically shown to contain viable cancer. In a combined retrospective consecutive series of 174 seminoma patients with postchemotherapy residual disease seen at ten treatment centers, empiric radiation was not associated with any medically significant improvement in PFS after completion of platinum-based combination chemotherapy.[
Although larger residual masses are more likely to harbor viable seminoma, the size of the residual mass is of limited prognostic value.[
Residual Masses After Chemotherapy in Men With Nonseminomas
Residual masses following chemotherapy in men with nonseminomatous germ cell tumors often contain viable cancer or teratoma, and the standard of care is to resect all such masses when possible. However, there are no randomized controlled trials evaluating this issue. Instead, the practice is based on the fact that viable neoplasm is often found at surgery in these patients, and the presumption is that such tumors would progress if not resected. If serum tumor markers are rising, salvage chemotherapy is usually given, but stable or slowly declining tumor markers are not a contraindication to resection of residual masses.
Case series of men undergoing postchemotherapy resections have reported that roughly 10% will have viable germ cell cancer, 45% will have teratomas, and 45% will have no viable tumors.[
However, only a small proportion of men have favorable enough features to have less than a 10% chance of having viable neoplasm in their residual masses, and thus the utility of current models has been questioned.[
When multiple sites of residual disease are present, all residual masses are generally resected. If it is not surgically feasible, resection is generally not performed. Some patients may have discordant pathological findings (e.g., fibrosis/necrosis, teratoma, or carcinoma) in residual masses in the abdomen versus the chest. Some medical centers perform simultaneous retroperitoneal and thoracic operations to remove residual masses,[
In a multi-institutional case series of surgery to remove postchemotherapy residual masses in 159 patients, necrosis only was found at thoracotomy in about 90% of patients who had necrosis only in their retroperitoneal masses. The figure was about 95% if the original testicular primary tumor had contained no teratomatous elements. Conversely, the histology of residual masses at thoracotomy did not predict nearly as well the histology of retroperitoneal masses.[
The presence of persistent malignant elements in the resected specimen is considered by some clinicians to be an indication for additional chemotherapy.[

Deciding on further treatment depends on many factors, including the specific cancer, previous treatment, site of recurrence, and individual patient considerations. Salvage regimens consisting of ifosfamide, cisplatin, and either etoposide or vinblastine can induce long-term complete responses in about 25% of patients with disease that has persisted or recurred following other cisplatin-based regimens. Patients who have had an initial complete response to first-line chemotherapy and those without extensive disease have the most favorable outcomes.[
High-dose chemotherapy with autologous marrow transplant has also been used in uncontrolled case series in patients with recurrent disease.[
A special case of late relapse may include patients who relapse more than 2 years after achieving complete remission; this population represents less than 5% of patients who are in complete remission after 2 years. Results with chemotherapy are poor in this patient subset, and surgical treatment appears to be superior, if technically feasible.[
Clinical trials are appropriate and should be considered whenever possible, including phase I and phase II studies for those patients who do not achieve a complete remission with induction therapy, or for those who do not achieve a complete remission following etoposide and cisplatin for their initial relapse, or for patients who have a second relapse.[
