Incidence and Mortality
Germ cell tumors of the ovary are uncommon but aggressive tumors, seen most often in young women and adolescent girls. These tumors are frequently unilateral and are generally curable if found and treated early. The use of combination chemotherapy after initial surgery has dramatically improved the prognosis for many women with these tumors.[
Dysgerminomas
One series found a 10-year survival rate of 88.6% following conservative surgery for patients with dysgerminoma confined to the ovary; smaller than 10 cm in size; with an intact, smooth capsule unattached to other organs; and without ascites.[
Other Germ Cell Tumors
A report of 35 cases of germ cell tumors, half of which were advanced stage or recurrent or progressive disease, demonstrated a 97% sustained remission at 10 months to 54 months after the start of a combination of BEP.[
Endodermal sinus tumors of the ovary are particularly aggressive. A review of the literature in 1979 prior to the widespread use of combination chemotherapy found only 27% of 96 patients with stage I endodermal sinus tumor alive at 2 years after diagnosis. More than 50% of the patients died within a year of diagnosis.
Patients with mature teratomas usually experience long-term survival, but survival for patients with immature teratomas after surgery only is related to the grade of the tumor, especially its neural elements. In a series of 58 patients with immature teratoma treated before the modern chemotherapeutic era, recurrence was reported in 18% of the patients with grade 1 disease, 37% of the patients with grade 2 disease, and 70% of the patients with grade 3 disease.[
Some studies have found that size and histology were the major factors determining prognosis for patients with malignant mixed germ cell tumors of the ovary.[

The following histological subtypes have been described.[

In the absence of obvious metastatic disease, accurate staging of germ cell tumors of the ovary requires laparotomy with careful examination of the following:
The contralateral ovary should be carefully examined and biopsied if necessary. Ascitic fluid should be examined cytologically. If ascites is not present, it is important to obtain peritoneal washings before the tumor is manipulated. In patients with dysgerminoma, lymphangiography or computed tomography is indicated if the pelvic and para-aortic lymph nodes were not carefully examined at the time of surgery.
Although not required for formal staging, it is desirable to obtain serum levels of alpha fetoprotein and human chorionic gonadotropin as soon as the diagnosis is established because persistence of these markers in the serum after surgery indicates unresected tumor.
The Fédération Internationale de Gynécologie et d'Obstétrique (FIGO) Staging
The FIGO and the American Joint Committee on Cancer (AJCC) have designated staging to define ovarian germ cell tumors; the FIGO system is most commonly used.[

Treatment options for patients with ovarian germ cell tumors include the following:
Patients may be treated with unilateral salpingo-oophorectomy or total abdominal hysterectomy and bilateral salpingo-oophorectomy.
All patients except those with stage I, grade I immature teratoma and stage IA dysgerminoma require postoperative chemotherapy. With platinum-based combination chemotherapy, the prognosis for patients with endodermal sinus tumors, immature teratomas, embryonal carcinomas, choriocarcinomas, and mixed tumors containing one or more of these elements has improved dramatically.[
References:
Dysgerminomas
Treatment options for stage I dysgerminomas include the following:
For patients with stage I dysgerminoma, unilateral salpingo-oophorectomy conserving the uterus and opposite ovary is accepted treatment of the younger patient who wants to preserve fertility or a pregnancy. Postoperative lymphangiography or CT is indicated before treatment decisions are made for patients who have not had careful surgical and pathological examination of pelvic and para-aortic lymph nodes during surgery.
Patients who have been completely staged and have stage IA tumors may be observed carefully after surgery without adjuvant treatment. About 15% to 25% of these patients will relapse, but they can be treated successfully at the time of recurrence with a high likelihood of cure.
Incompletely staged patients or those with higher stage tumors should probably receive adjuvant treatment. Options include radiation therapy or chemotherapy. A disadvantage of the former is loss of fertility resulting from ovarian failure. Experience with adjuvant chemotherapy is limited, but considering the effectiveness of chemotherapy in tumors other than dysgerminoma and in advanced stage dysgerminoma, adjuvant chemotherapy is likely to be very effective and to allow recovery of reproductive potential in patients with an intact ovary, fallopian tube, and uterus.[
Other Germ Cell Tumors
Treatment options for patients with other stage I germ cell tumors include the following:
For patients with stage I germ cell tumors, unilateral salpingo-oophorectomy should be performed when fertility is to be preserved. For all patients with tumors other than pure dysgerminoma and low-grade (grade I) immature teratoma, chemotherapy is usually given postoperatively, although a series demonstrated excellent survival for patients with all types of stage I tumors managed by surveillance, reserving chemotherapy for cases in which postsurgery recurrence is documented.[
There is considerable experience with a combination of vincristine, dactinomycin, and cyclophosphamide (VAC) given in an adjuvant setting; however, combinations containing cisplatin, etoposide, and bleomycin (BEP) are now preferred because of a lower relapse rate and shorter treatment time.[
Evidence suggests that second-look laparotomy is not beneficial in patients with initially completely resected tumors who receive cisplatin-based adjuvant treatment.[

Dysgerminomas
Treatment options for patients with stage II dysgerminomas include the following:
For patients with stage II dysgerminoma, total abdominal hysterectomy and bilateral salpingo-oophorectomy are usually performed. For the younger patient who wants to preserve fertility, a unilateral salpingo-oophorectomy may be considered standard therapy, depending on the age of the patient, and adjuvant chemotherapy should be given.
These patients should receive adjuvant treatment. Options include radiation therapy or chemotherapy. A disadvantage of the former is loss of fertility resulting from ovarian failure. Experience with adjuvant chemotherapy is limited, but considering the effectiveness of chemotherapy in tumors other than dysgerminoma and its effectiveness in advanced-stage dysgerminoma, adjuvant chemotherapy is likely to be effective and to allow recovery of reproductive potential in patients with an intact ovary, fallopian tube, and uterus. Thus, adjuvant chemotherapy with the combination of bleomycin, etoposide, and cisplatin (BEP) has replaced radiation therapy except in the rare patient in whom chemotherapy is not considered appropriate.
Other Germ Cell Tumors
Treatment options for patients with other stage II germ cell tumors include the following:
For patients with stage II germ cell tumors other than pure dysgerminoma, unilateral salpingo-oophorectomy should be performed when fertility is to be preserved. Although there is considerable experience with the combination of vincristine, dactinomycin, and cyclophosphamide (VAC), especially when given in an adjuvant setting, BEP is more effective.[
Evidence suggests that second-look laparotomy is not beneficial in patients with initially completely resected tumors who receive cisplatin-based adjuvant treatment.[

Dysgerminomas
Treatment options for patients with stage III dysgerminomas include the following:
For patients with stage III dysgerminoma, total abdominal hysterectomy and bilateral salpingo-oophorectomy are recommended with removal of as much gross tumor as can be done safely without resection of portions of the urinary tract or large segments of the small or large bowel. Patients who want to preserve fertility may be treated with unilateral salpingo-oophorectomy if chemotherapy is to be employed.[
Combination chemotherapy with bleomycin, etoposide, and cisplatin (BEP) can cure most of these patients. In a report of results from two Gynecologic Oncology Group (GOG) trials, 19 of 20 patients with incompletely resected tumors who were treated with BEP or cisplatin, vinblastine, and bleomycin (PVB) were disease free at a median follow-up of 26 months.[
Other Germ Cell Tumors
Treatment options for patients with other stage III germ cell tumors include the following:
For patients with stage III germ cell tumors other than pure dysgerminoma, total abdominal hysterectomy and bilateral salpingo-oophorectomy is recommended with removal of as much tumor in the abdomen and pelvis as can be done safely without resection of portions of the urinary tract or large segments of the small or large bowel. Patients who wish to preserve fertility can be treated with unilateral salpingo-oophorectomy.[
Evidence suggests that second-look laparotomy is not beneficial in patients with initially completely resected tumors who receive cisplatin-based adjuvant treatment.[

Dysgerminomas
Treatment options for patients with stage IV dysgerminomas include the following:
For patients with stage IV dysgerminoma, total abdominal hysterectomy and bilateral salpingo-oophorectomy is recommended with removal of as much gross tumor in the abdomen and pelvis as can be done safely without resection of portions of the urinary tract or large segments of small or large bowel, although unilateral salpingo-oophorectomy should be considered in patients who wish to preserve fertility.[
Other Germ Cell Tumors
Treatment options for patients with other stage IV germ cell tumors include the following:
For patients with stage IV germ cell tumors other than pure dysgerminoma, total abdominal hysterectomy and bilateral salpingo-oophorectomy is recommended with removal of as much tumor from the abdomen and pelvis as can be done safely without resection of the kidney or large segments of the small or large bowel. Patients who wish to preserve fertility can be treated with unilateral salpingo-oophorectomy. Following maximal surgical debulking, three to four courses of cisplatin-containing combination chemotherapy are indicated.[
Second-look surgery may be of benefit for a minority of patients whose tumor was not completely resected at the initial surgical procedure and who had teratomatous elements in their primary tumor.[
