ovarian CA

Ovarian cancer is often diagnosed at a late stage, leading to a poor prognosis and a significantly lower five-year survival rate compared to other cancers like cervical cancer, which benefits from effective screening methods.

poor prognosis

prognostic factors

40% 5 years survival present late no screening like cervical CA because no premalignant state etc

types

epithelial commonest 80% stromal-sex cord 10% germ cell 10% krukenberg-mets from breast, stomach, colon

platynum resistense

surgery
further debulking can be done if bulky disease persisted
neoadjuvent chemo and interval debulking this improves postop morbidity but doesn't improve survival
postop

chemotherapy need in staging

paclitaxol

pre emptive steroids are given to reduce hypersensitive reactions peripheral neuropathy neutropenia loss of total body hair

Platinum compound most effective agents

carboplatin dose calculated according to GFR using AUC
