Abstract
To test the feasibility of fine needle (22 gauge) percutaneous intratumoral chemotherapy (PIC) under ultrasound guidance, a trial was conducted on 12 selected neoplastic patients with tumors not responsive to conventional treatments (5 adenocarcinomas of the pancreas, 1 hepatocellular carcinoma, 1 squamous cell carcinoma of the lung, 1 leiomyosarcoma of the hepatic hilum, 1 malignant fibrous histiocytoma of the ischiatic region, 2 liver and 1 peritoneal metastases). The drugs used were 5-fluorouracil, methotrexate and cyclophosphamide, according to the histotype. The doses given never exceeded the routine intravenous doses; 119 sessions of PIC were administered. There have been no significant local complications due to needle injury and drug toxicity or biochemical changes attributable to general toxicity. Partial or total pain control and stable disease or response to 60% was observed. This research has not been described previously to our knowledge.
