My husband was diagnosed with Stage IV colorectal cancer with metastasis to the liver. When he had a liver resection in July 2013 the surgeon found 3 cancerous nodules in the right diaphragm and removed them. He had a questionable small tumor that responded to folfox and avastin therapy. In January his ct scans of the chest and pelvis were good and his CEA was 3.2 so we decided to hold chemotherapy for 3 months to evaluate the lung tumor. In April the CT scan of chest showed an increase in size of tumor from 1.4 cm to 2.5 cm. The ct scan of the pelvis showed 2 tumors in the omentum that are 1.4 and 1.6 cm in diameter. The oncologist recommends chemotherapy with folfiri and avastin. According to the research systemic chemotherapy is not that helpful with peritoneal carcinomatosis. Is there any other treatment available for him?
Thanks for your question on Chat Doctor. I can understand your situation and problems. Stage 4 colorectal cancer has very poor prognosis. Life expectancy is less than 1 year. For peritoneal carcinomatosis systemic chemotherapy is treatment of choice. Another way is local instillation of chemotherapy Chat Doctor.  Direct injection of chemotherapy
