BRCA breast cancer gene, ER estrogen receptors, PR progesterone receptors, HER2 human epidermal growth factor receptor-2, WT1 Wilms’ tumor 1 suppressor gene, GCDFP-15 gross cystic disease fluid protein, CK7 cytokeratin-7, CK20 cytokeratin-20


None of the patients were breast cancer gene (BRCA) mutation carriers, and all patients’ tumors tested negative for WT1 and Ca-125 and positive for GCDFP-15. Surgical-related morbidity and mortality are shown in Table 9.3. After receiving HIPEC, one patient experienced a transient grade II cisplatin renal toxicity reversed by medical treatment and one patient a moderate pancreatitis requiring medical treatment. The mean PCI was 19 (range 15–24). Long-term survival is reported in Table 9.4. Of the seven patients, four are presently alive and disease-free at 11, 58, 117, and 135 months.
