Primary Peritoneal Cancer (PPC) is a rare malignancy that arises from the peritoneum—the thin layer lining the abdominal cavity—yet closely resembles epithelial ovarian cancer in behavior and treatment needs. Symptoms often overlap with ovarian malignancies, including abdominal swelling, pain, and fluid accumulation (ascites). Diagnosis typically relies on imaging, tumor markers (like CA‑125), fluid analysis, and surgical biopsy. Given that traditional intravenous chemotherapy has limited efficacy due to low drug delivery to the peritoneum, advanced treatment strategies such as cytoreductive surgery combined with HIPEC (Heated Intraperitoneal Chemotherapy) and PIPAC (Pressurized Intraperitoneal Aerosol Chemotherapy) have emerged as highly effective alternatives. These methods enable direct, targeted delivery of chemotherapeutic agents into the abdominal cavity, improving response while minimizing systemic side effects Dr Ninad Katdare, a surgical oncologist based in Mumbai, specializes in treating peritoneal surface malignancies—including PPC—with cutting-edge interventions. Trained extensively in cytoreductive surgery and HIPEC at CHU Lyon, and as one of India’s pioneers of PIPAC, he has performed over 250 CRS/HIPEC procedures and led the introduction of PIPAC in multiple Indian centers.His efforts have brought hope to many patients previously considered inoperable, leveraging highly targeted and minimally invasive procedures to achieve better outcomes and improved quality of life.
