Treatment of malignant ovarian germ cell tumors with preservation of fertility: a report of 28 cases

Cancer of the ovary, fallopian tube, and peritoneum

The Gynecologic Oncology Committee of FIGO in 2014 revised the staging of ovarian cancer, incorporating ovarian, fallopian tube, and peritoneal cancer into the same system. Most of these malignancies are high-grade serous carcinomas (HGSC). Stage IC is now divided into three categories: IC1 (surgical spill); IC2 (capsule ruptured before surgery or tumor on ovarian or fallopian tube surface); and IC3 (malignant cells in the ascites or peritoneal washings). The updated staging includes a revision of Stage IIIC based on spread to the retroperitoneal lymph nodes alone without intraperitoneal dissemination. This category is now subdivided into IIIA1(i) (metastasis ≤10 mm in greatest dimension), and IIIA1(ii) (metastasis >10 mm in greatest dimension). Stage IIIA2 is now "microscopic extrapelvic peritoneal involvement with or without positive retroperitoneal lymph node" metastasis. This review summarizes the genetics, surgical management, chemotherapy, and targeted therapies for epithelial cancers, and the treatment of ovarian germ cell and stromal malignancies.

Fertility-preserving surgery for advanced stage ovarian germ cell tumors

OBJECTIVE

To evaluate the prevalence and safety of uterine preservation among premenopausal women diagnosed with a malignant ovarian germ-cell tumor (MOGCT) of advanced stage (stage II-IV).

MATERIALS AND METHODS

The National Cancer Database was accessed and a cohort of women aged <40years, diagnosed with a MOGCT were identified. Those with stage II-IV disease who underwent cancer-directed surgery and received chemotherapy were selected for further analysis. Performance of hysterectomy was assessed from site-specific surgery codes. Overall survival (OS) was determined following generation of Kaplan-Meier curves and compared with the log-rank test. A Cox multivariate model was constructed to control for possible confounders.

RESULTS

A total of 526 eligible patients were identified; rate of hysterectomy was 20.2%. Women who had a hysterectomy were older (median age 30.5 vs 20years, p<0.001) and more likely to present with bilateral tumors (12.6% vs 3.8%, p<0.001). No differences were noted based on tumor histology (p=0.67). Rate of uterine preservation was 82.8%, 79.5% and 75% for those with stage II, III and IV disease respectively (p=0.46). There was no difference in OS between women who had hysterectomy and those who did not (p=0.051); five-year OS rates were 87.1% and 94.4% respectively. After controlling for disease stage, tumor histology and patient race, uterine preservation was not associated with a decreased survival (HR: 0.59, 95% CI: 0.28, 1.24, p=0.19).

CONCLUSIONS

Uterine preservation was not associated with decreased survival and should be considered in women with advanced stage GCTs interested in future fertility.

Successful infertility treatment following fertility-sparing surgery and chemotherapy for ovarian immature teratoma: a case report and a literature review

Introduction

Malignant ovarian germ cell tumors (MOGCTs) are highly chemosensitive tumors most commonly found in adolescent girls and young women. However, patients with advanced disease can now be successfully cured with fertility-sparing surgery and adjuvant chemotherapy, resulting in childbearing.

Case

A 24-year-old nulliparous Japanese woman was diagnosed as having a stage IIIc immature teratoma. After fertility-sparing surgery, she received four cycles of chemotherapy consisting of cisplatin, etoposide, and pepleomycin. She married at the age of 34, but did not conceive due to sexual dysfunction of her husband. At the age of 38, intrauterine insemination was performed following ovulation induction with clomid and human menopausal gonadotrophin, which resulted in a singleton pregnancy. A healthy female infant was delivered at 38 weeks' gestation.

Conclusion

Treatment might sometimes be needed for infertile women with a history of MOGCTs, but further studies are needed to determine whether infertility treatment, including ovulation induction, is appropriate.

Multidisciplinary management of malignant ovarian germ cell tumours

OBJECTIVES

Malignant ovarian germ cell tumours (MOGCT) are rare cancers of young women. Limited prospective trials exist from which evidence-based management can be developed. This review summarizes the available literature concerning MOGT in order to provide the clinician with information relevant to their multidisciplinary management.

METHODS

MEDLINE was searched between 1966 and 2010 for all publications in English where the studied population included women diagnosed with malignant ovarian germ cell tumours.

RESULTS

The majority of patients can be cured with fertility-preserving surgery with or without combination chemotherapy. Long term survival approaches 100% in early stage disease and is approximately 75% in advanced stage disease. Most studies suggest that the treatment has little, if any, effect on future fertility and limited data suggest that there is no adverse effect on the future quality of life.

CONCLUSION

MOGCTs are rare tumours of young women the majority of which can be successfully treated with fertility-preserving surgery with or without chemotherapy with preservation of reproductive function. Minimisation of chemotherapy in good prognostic groups and improved treatment in resistant and relapsed MOGCT are important goals for the future. Further studies are needed to quantify the late adverse effects of treatment in long term survivors.

Survival and reproductive outcomes in women treated for malignant ovarian germ cell tumors

OBJECTIVE

The objective of this study is to review all malignant germ-cell tumors (MOGCTs) treated at our institution, focusing on reproductive outcomes and menstrual function of patients treated with fertility-sparing surgery and adjuvant chemotherapy.

METHODS

We performed a retrospective chart review of patients treated for MOGCTs between January 1, 1979 and March 31, 2008. Charts of identified patients were abstracted and data were collected. Patients who had fertility-sparing surgery were contacted and a telephone questionnaire was performed to gather reproductive and menstrual history.

RESULTS

Forty patients were treated for MOGCTs at our institution. Mean age at the time of diagnosis was 26.5years (range, 10-48years). Histologic subtypes were: immature teratoma (52.5%), dysgerminoma (27.5%), yolk sac tumor (10.0%), mixed germ cell tumor (7.5%), and choriocarcinoma (2.5%). Thirty-five percent of tumors were FIGO stages II-IV. Twenty-seven patients (67.5%) were treated with chemotherapy postoperatively, 23 (85%) of whom received bleomycin, etoposide and cisplatin (BEP). There were three recurrences, but no deaths. Fertility-sparing surgery was performed in 22 patients (55%), 16 of whom received adjuvant chemotherapy. Fourteen of these patients were contacted. Of the 10 remaining patients desiring pregnancy, 8 (80%) had 11 successful spontaneous pregnancies, one required in-vitro fertilization, and the other required donor egg in-vitro fertilization, resulting in 14 live births. All 14 patients had normal menstrual cycles within one year of completing chemotherapy.

CONCLUSIONS

Overall survival was 100% among patients with both local and advanced MOGCTs, including those who underwent fertility-sparing surgery. Fertility-sparing surgery plus adjuvant chemotherapy appeared to have little or no effect on fertility or menstrual cycles.

Preservation of ovarian function, reproductive ability and emotional attitudes in patients with malignant ovarian tumors

OBJECTIVES

Although cancer is predominantly a disease of aging, an increasing number of women survive malignancies before or during their reproductive years, which may interfere with their fertility potential. Although a variety of studies have tried to document the impact of conservative treatment aimed at preserving ovarian function and reproductive ability, little information has been available regarding survivors' attitudes, emotions, and choices to have children. The aim of this study is to evaluate the reproductive history, experiences, attitudes, and emotions with regard to having children in conservatively treated patients with Stage I epithelial ovarian cancer, any stage LMP tumors, malignant ovarian germ cell tumors (MOGCTs) and Stage I sex cord-stromal tumors (SCSTs).

STUDY DESIGN

Between 1986 and 2000, a total of 75 patients with primary malignant ovarian tumors underwent conservative treatment. Out of 75 patients in the study, 14 women (19%) presented Stage I epithelial ovarian cancer, 23 (31%) LMP tumors, 33 (43%) MOGCTs, and five (7%) SCSTs. Information was obtained from medical records and from a questionnaire mailed to all patients who were at least 15 years old at the time of the diagnosis (68 subjects). Median time of follow-up was 102 months (35-192 months). There were four (5.2%) clinical recurrences within 35 months. Only 20 patients (49%) had tried to conceive after the completion of their treatment; of these, 15 women (75%) succeeded and delivered 19 healthy children. Seventy percent (32/41) of the respondents claimed that their disease did not have any impact on their desire to have children. Whereas 51% (21/41) fear that their ovarian disease could have damaged their reproductive potential, 76% (31/41) are not concerned about the effects of the treatment they received on offspring. The impact of the disease on the patients' attitudes toward life was reported as positive.

CONCLUSION

The results from our study, in agreement with the data from the literature, confirm that management of Stage I (grade 1, grade 2) epithelial ovarian cancer, any stage LMP tumors, MOGCTs and Stage I SCSTs with fertility-sparing surgery is a safe, practicable treatment option. Though preliminary, this survey provides insight into the attitudes and experiences of young women ovarian cancer survivors regarding fertility.

Assistance médicale à la procréation après traitement conservateur d'une tumeur de l'ovaire invasive ou à la limite de la malignité

OBJECTIVE

Ovulation induction, the usual resort of Assisted Reproductive Technologies (ART), has been suspected of carrying a responsibility in the genesis of ovarian tumours. For patients with a borderline or invasive ovarian tumour, treated by conservative surgery and desiring to become pregnant, the problem is thus of a possible resort to the Assisted Reproductive Technologies.

PATIENTS AND METHODS

This is a multicenter, national and retrospective study. 40 operated patients between January 1971 and January 2001 have been included. 27 patients (67.5%) had a borderline tumour, 10 (25%) a non-epithelial tumour (germinal or stromal) and 3 (7.5%) an epithelial invasive carcinoma. All these patients have benefited from a conservative surgical management of fertility. The Assisted Reproductive Technologies were simple stimulation for 5 women and IVF for the 35 others. The effectiveness and the risks of Assisted Reproductive Technologies have been estimated respectively by the number of pregnancies obtained and the recurrence rates.

RESULTS

With a global follow-up of 372 months (January 1971: date of the primary surgical procedure--June 2002: closing of the study), 17 patients have obtained 17 pregnancies with the Assisted Reproductive Technologies, rate of 42.5% (17/40): 1 spontaneous abortion, 16 delivery with 23 children (triple pregnancies and 3 twin pregnancies). 3 patients treated for a borderline tumour have had a recurrence after induction of ovulation. Among the 40 patients, no one presented an evolved disease at the last news. The patients who had a recurrence had a delay to begin the Assisted Reproductive Technologies significantly lower than the patients who had no recurrence.

DISCUSSION AND CONCLUSION

The assisted reproductive technologies for patients who had been treated for a borderline or invasive ovarian tumour, and who were infertile in spite of conservative management, have allowed 42.5% of these women to obtain a pregnancy and does not seem to increase significantly the risk of recurrence.

Infertility rates following POMB/ACE chemotherapy for male and female germ cell tumours - a retrospective long-term follow-up study

The risk of chemotherapy-induced infertility in male and female germ cell tumour (GCT) survivors is unclear, but may correlate with cisplatin dose. Here, we examine a large series of GCT patients for the effect of chemotherapy on those attempting to have children. Our GCT database was screened for nonseminomatous GCT patients who had (1) received POMB/ACE chemotherapy (cisplatin, vincristine, methotrexate, bleomycin alternating with actinomycin D, cyclophosphamide and etoposide) and (2) stage I male GCT patients who were untreated between 1977 and 1996. Fertility was assessed by questionnaire and medical records. A total of 64 of 153 treated and 35 of 115 untreated men attempted to have children. In all, 28% (18 out of 64) receiving POMB/ACE were unsuccessful. Radiotherapy (six), atrophic remaining testis (one) or prior infertility (three) were implicated in 10 cases, so chemotherapy-induced infertility may have occurred in only 11% (eight out of 64). Strikingly, 26% (nine out of 35) of untreated stage I patients also failed to have children (three had radiotherapy, three prior infertility). Moreover, in treated men, no association was seen between cisplatin dose and infertility. In contrast, radiotherapy significantly increased male infertility (P=0.001). Of 28 treated women who attempted to have children, 25% (seven out of 28) were unsuccessful. One previously had infertility and one subsequently had successful IVF so chemotherapy-induced infertility potentially occurred in only 18% (five out of 28) and was not related to cisplatin dose. In conclusion, the risk of chemotherapy-induced infertility is low in both male and female GCT patients and does not clearly correlate with the cumulative cisplatin dose.

Ovarian tissue cryopreservation and gynecologic oncology: a review

Sperm cryopreservation permits young men, undergoing cancer treatments, to preserve their fertility. Ovarian tissue cryopreservation have the same goal for young women and could also be an option for children. However, only primordial follicles survive after freezing and a follicular maturation is needed after thawing. This maturation has not yet been realized in humans, pregnancies have only been obtained in animal models. As cryopreservation is yet effective in humans, many teams have already cryopreserved the ovarian tissue of patients who have nothing to lose as their follicular reserve would have been destroyed or severely depleted by cancer treatment. The preservation of fertility is rarely an issue in gynecologic oncology because it usually concerns post-menopausal women. However, they are early-onset forms of gynecologic cancers and in these cases fertility is often threatened. Ovarian tissue cryopreservation may be performed when curative or prophylactic ovariectomy must be undergone, when chemotherapy with high-dose alkylating agents is planned or when pelvic radiation is needed (particularly in cases requiring chemotherapy combined with radiotherapy). In some of these situations it would be dangerous to graft back the tissue to the patient as cancer cells could remain within the grafts, the best solution in this case would be the in vitro follicular maturation.

Prognostic factors of patients with yolk sac tumors of the ovary

OBJECTIVE

Our purpose was to evaluate the prognostic factors in yolk sac tumors of the ovary.

STUDY DESIGN

We performed a retrospective review of 47 patients with yolk sac tumors of the ovary from 1979 to 1997.

RESULTS

Twenty-two patients had pure yolk sac tumors and 25 had germ cell tumors with yolk sac tissue as a component of the disease. The 5-year survival rate in stages I, II, III, and IV was 95%, 75%, 30%, and 25%, respectively. Patients with stage I disease had a more favorable prognosis than those with stage III and IV disease (P <.001). All patients who did not respond to chemotherapy died of this disease within 36 months of the first treatment. Chemotherapy regimens that included cisplatin gave better results than those without cisplatin (P <.05). The difference in prognosis was significant in cases in which the size of residual tumor was <2 cm in diameter (P <.01) and in cases in which ascites was either absent or <100 mL in volume (P <.05). Coexistence of other components of ovarian germ cell tumors in histologic specimens, preoperative serum alpha-fetoprotein level, fertility-sparing surgery, dissection of intrapelvic nodes, and p53 status had no significant correlation with the prognosis in this study.

CONCLUSIONS

Staging and tumor-reductive surgery strongly affected the prognosis of this disease. Tumor-reductive surgery is advisable when ascites is minimal. Cisplatin-based chemotherapy after surgery was superior to chemotherapy without cisplatin; however, p53 status seemed to have no impact on chemosensitivity in yolk sac tumors of the ovary.

Treatment of malignant ovarian germ cell tumors with preservation of fertility: reproductive performance after persistent remission

To describe our experience with malignant ovarian germ cell tumors with special reference to reproductive performance after remission, medical records of 31 patients were reviewed. The mean age at diagnosis was 18.6 years. Tumor by stage was I in 16 cases, II in 5, III in 5, IV in 3, and recurrence in 2. Histology was dysgerminoma in 7 cases, yolk sac tumor in 10, immature teratoma in 7, choriocarcinoma in 1, and mixed-type tumor in 6. Conservative surgery for fertility preservation was performed in 21 cases. Postoperative chemotherapy was given to all cases except two with stage Ia dysgerminoma. Of 31 cases, 4 including one fertility-preserved case died of disease. The other 27 cases including 20 fertility-preserved cases were successfully treated. Twenty-five cases (92.6%) have been followed longer than 60 months and 13 cases (48.1%) longer than 120 months. By the last follow-up, 8 of the 20 fertility-preserved cases delivered a total of 9 normal babies. Of the remaining 12 nonpregnant cases, 3 married, 9 have had regular menses, and 3 have had menstrual problems. Two of the latter three cases have been in hypergonadotropic anovulatory cycles. One patient has been diagnosed with tubal infertility caused by peritubal adhesion. Thus, management of the disease with fertility preservation is safe and the majority of patients can attain or retain normal ovarian function and reproductive potential.

Recent management of malignant ovarian germ cell tumors: a study of 34 cases

OBJECTIVE

To review the outcome of the treatment in patients with malignant ovarian Germ cell tumors with respect to survival and surgical management at a single institution during 1990-1996.

METHODS

Thirty-four patients with malignant ovarian Germ cell tumors were studied retrospectively for their surgical management. Fourteen patients had pure dysgerminoma, 11 endodermal sinus tumor, 6 immature teratoma, and 3 mixed Germ cell tumors. Nine patients had stage IA, 8 stage IC, 2 stage IIC, 8 stage III, 3 stage IV, and 4 referred patients with recurrent diseases.

RESULTS

Nineteen patients underwent primary conservative surgery, 11 had primary nonconservative surgery. Twenty-two patients were treated with chemotherapy (BEP or EP or PVB regimen). Five patients with pure dysgerminoma received adjuvant radiotherapy. Persistent remission was achieved in 26 patients. Two patients (7.4%) had recurrence after remission. Seven patients had died of the diseases. Patients with complete clinical remission did not undergo second-look surgery. The overall survival was 78.8%, 100% for immature teratoma, 84.6% for pure dysgerminoma, 72.8% for endodermal sinus tumor, and 33.3% for mixed Germ cell tumors, with median follow-up time 31 (3-93) months.

CONCLUSION

Patients with limited diseases regardless of histologic types can be safely managed by unilateral salpingo-oophorectomy followed by, if indicated, 3-4 courses of cisplatin-based chemotherapy. For advanced diseases, conservative surgery is advisable in patients with endodermal sinus tumor.

Premature menopause after cancer treatment

PURPOSE

The purpose of this report is to examine the impact that cancer therapies have on ovarian function.

OVERVIEW

Symptoms of and conditions due to estrogen deficiency after cancer therapy are described, and interventions are proposed. The consequences of short-term as well as prolonged estrogen deficiency-including vasomotor instability, infertility, genitourinary atrophy, coronary artery disease, and osteoporosis-are discussed.

CLINICAL IMPLICATIONS

Symptoms and conditions associated with premature menopause may cause additional stress for women who undergo cancer therapy. Knowledge about what happens to these women can enable healthcare providers to help them make decisions about cancer treatment, engage in self-care activities, and explore options for preserving fertility.

Reproductive sequelae of cancer treatment

Remarkable advances have been made in the treatment of cancers that afflict patients of the reproductive age. Many survivors must now face the effects on gonadal function and have concerns about reproductive capacity. The sequelae of different modalities of cancer therapy specifically addressing surgery, chemotherapy, and radiotherapy on reproductive system are reviewed. Assisted reproductive technologies, prenatal diagnosis methods, and contraception counseling are briefly summarized in conclusion.

Abdominal wall metastases after surgical resection of an immature teratoma of the ovary

In this case report the diagnostic process is discussed leading to a rather late correct diagnosis of immature teratoma. The authors advice preoperative determination of alpha-fetoprotein in all women with ovarian tumours under 40 years of age. The limitations for pathologists to assess immaturity within a teratoma are stressed.

Conservative surgery for ovarian cancer and effect on fertility

OBJECTIVE

A survey that compared two alternatives (conservative and radical surgery) is presented on ovarian cancer treatment evaluating its effect on progression-free survival and fertility, in a 10-year time period, in Mexican women.

METHODS

72 women between 11 and 58 years old with unilateral ovarian cancer in different stages were studied. Several methods were analyzed: (1) progression-free survival, using Mantel and Haenzsel test to compare in terms of life curves and the Kaplan-Meier method. The exposure variable was surgery type, using the Mantel-Cox test to evaluate the difference in life curves by clinical stages and by surgery type; (2) fertility was evaluated in women who received conservative surgery, considering the cumulative pregnancy rate in women successfully pregnant after surgical and/or adjuvant treatment.

RESULTS

There were no difference in survival curves when evaluating progression-free survival, in either group (Z = 1.09 and Pr > (z) = 0.27). During the study period, we found that 87.5% of patients were alive with no evidence of disease. There were no differences in survival curves when evaluating progression-free survival according to surgery type and clinical stage (chi 2 = 0.66, P = 0.88). Restart of menstruation in patients with conservative surgery occurred before 6 months in 89% of the sample, 22 women with possible parity had a 59.1% cumulative pregnancy rate.

CONCLUSION

The outcomes from this survey carried out in Mexico show that conservative treatment of ovarian cancer in early clinical stages is an efficient alternative to preserve reproductive function in young women, and does not show differences in progression-free survival compared to radical surgery.

Malignant germ cell tumors of the ovary: a study of 20 cases

In a study of 20 patients diagnosed with malignant ovarian germ cell tumors between 1961 and 1993, clinical and pathologic findings were evaluated. Of the 20 patients, seven (35%) had dysgerminoma, two (10%) endodermal sinus tumor, three (15%) malignant teratoma, one (5%) malignant struma ovarii, one (5%) primary ovarian carcinoid, two (10%) benign teratoma with malignant transformation, and four (20%) combination germ cell tumor. Twelve patients (60%) had stage IA, five (25%) stage IC, and three (15%) stage IIIC. Twelve patients (60%) underwent conservative surgery and eight (40%) had at least bilateral salpingo-oophorectomy. At follow-up, 18 patients (90%) were alive free of disease, one (5%) had died of disease, and one (5%) had died of intercurrent disease. The actuarial 5-year survival rate was 93.3%. It is concluded that for young women who wish to preserve child-bearing capacity, regardless of the stage of the tumor, fertility-preserving surgery with complete surgical staging followed, if necessary by cisplatin-based combination chemotherapy is an appropriate and definitive treatment in the absence of involvement of the contralateral ovary and uterus. For patients in whom child-bearing capacity is not an issue, surgery should include total abdominal hysterectomy and bilateral salpingo-oophorectomy with complete staging, followed if necessary by chemotherapy.

Effects of cancer on the sexuality and fertility of women

As more Americans become cancer survivors, sexuality and fertility have become more paramount issues in cancer care. Both the disease and the treatments used can produce both short-term and long-term effects that can confound sexual expression and fertility. The identification of these sequelae in survivors of cancer has led to the exploration of methods to predict, prevent, or minimize their occurrence. This article addresses the effects of cancer and cancer care in those undergoing treatment and surviving the array of diseases known as cancer.

Extra gonadal germ cell tumours: report of two cases

Extra gonadal germ cell tumours (EGGCT) in women are rare. We report here two such patients. The clinical and laboratory features were--young age, 25 and 22 years, midline location (mediastinum, scalp), elevated tumour marker and normal ovaries on CAT scan. The histological subtype was embryonal carcinoma in both cases. Complete response (CR) was achieved with cisplatin based chemotherapy (CT). Both patients had return of normal ovarian functions and have delivered normal babies (1st patient one, 2nd patient 2 babies). Both remain asymptomatic and disease-free at 30 + and 55 + months follow-up. We conclude that patients with EGGCT after treatment with cisplatin based CT achieve CR with return of normal ovarian functions and prolonged survival.
