|The WHO classification of ovarian tumors has four broad sub groups: Epithelial tumors, Sex cord-stromal tumors, Germ cell tumors, and Gonadoblastoma. The surgical management for dyspgerminomas and non�dysgerminomas is fertility sparing surgery (FPS). Chemotherapy with protocols like PEB is advocated for germ cell tumors > stage IA. With the PEB protocol for 3 � 4 cycles, 80% regain normal menstrual function with several documented pregnancies. Various phase 3 trials in advanced EOCs (Epithelial Ovarian Cancers) have established Paclitaxel + Carboplatin every 3 weeks for 6 cycles as the standard of care (2004 GCIG recommnended standard) with a median PFS of 15.4 � 16.4 months and 30�35% 5 year overal survival (OS). Substitution of Paclitaxel (with Docetaxel or PLD), maintenace Paclitaxel for 1 year, Consolidation chemotherapy with Topotecan, adding a 3rd drug to Paclitaxel and Carboplatin have all shown no advantage. Intraperitoneal chemotherapy and dose�dense chemotheray have shown an OS benefit at the expense of higher grade 3 and grade 4 side effects. The GOG 218 trial incorporating Avastin for 15 months and the ICON7 trial incorporating Avastin for 12 months showed a statically significant improvement in the PFS when compared to Paclitaxel + Carboplatin. In Platinum sensitive recurrent EOC, adding Avastin to Gemcitabine + Carboplatin (as in the OCEANS trial) showed a significant PFS benefit. In platinum resistant recurrent EOC, adding Avastin to various chemotherapy options (Investigator�s choice) showed a significant PFS benefit. Avastin, therefore, seems to be the ideal partner of choice with chemotherapy in advanced EOC as first-line and in platinum-sensitive and platinum-resistant recurrent ovarian cancer.|
