Ovary: Oral Abstract: Single centre experience of ovarian germ cell tumours over 8 years
This article was originally published by Wolters Kluwer - Medknow and was migrated to Scientific Scholar after the change of Publisher.
Abstract
Introduction:
Germ cell tumours comprise approximately 15-20% of all ovarian tumours. Two third of ovarian tumours in first two decades of life are germ cell tumours. Majority of ovarian germ cell tumours are benign teratomas. The malignant germ cell tumours are usually solid and arise from totipotent germ cells. Over the past 3 decades the clinical outcome of women with ovarian germ cell tumours (OGCT) have significantly improved mainly due to development of more effective chemotherapy regimens.
Objective:
To study the clinic pathological features, treatment and survival of women with ovarian germ cell tumours.
Methods:
This is a retrospective descriptive study taken from the case files of patients with histo-pathologically proven ovarian germ cell tumours who were treated in JIPMER over 8 years from 2007 to 2014.
Results:
There were totally 63 patients with ovarian germ cell tumours over 8 years who were treated in JIPMER. The age at presentation varies from 12 years to 65 years with a median age of 26.5 years. Three were pre pubertal and 1 was post-menopausal. Twenty two women (34%) were unmarried and 5 were pregnant at the time of presentation. Forty eight (76%) of them did not have any menstrual abnormalities. Pain abdomen (55%) was the most common presentation. Ten of them presented with acute abdomen of which 8 were torsion, 1 was ruptured dermoid and 1 was infected dermoid. Another 6 patients had torsion which was diagnosed only during surgery. Majority (68%) were benign tumours (dermoid) and among malignant tumours, there were 6 dysgerminomas, 5 immature teratomas, 5 mixed germ cell tumours and 4 yolk sac tumours. Almost half (22 out of 43) of women with benign tumours were <25 years whereas 3/4th (14 out of 20) of women with malignant germ cell tumours were <25 years. The most common tumour marker which was elevated was alpha feto protein (8) followed by LDH (5). Fertility sparing surgery (salpingo-ovariotomy) was commonly performed which was 95% (41/43) in benign tumours and 60% (8/20) in malignant tumours. Contra lateral ovary was biopsied in only 5 patients with suspected involvement (negative on final HPR). Out of 20 women with malignant ovarian tumours 7 were in advanced stage (Stage III). Majority of them recovered well from surgery, only 12% had post-operative febrile morbidity and one patient had subclavian vein thrombosis on post op D9 which required anticoagulants. 7 of 20 women received chemotherapy (BEP) for 4 cycles. No serious side effects of chemotherapy were noted in these women. 3 out of 20 women with malignant germ cell tumour were lost to follow up. No recurrences have been found in rest of the women and there are no deaths till last follow up.
Conclusion:
Advances in the field of medicine like effective chemotherapy regimens, improved imaging, precise surgical staging and fertility sparing surgical procedures enable women not only to preserve the reproductive function but also to improve their quality of life.
