The authors report their 12 years of experience of intra arterial chemotherapy in pelvic recurrences and inoperable advanced stages of uterine carcinoma, rectal cancer and anal cancer. In squamous cell cancers the drug associations were mitomycin C, bleomycin, fluorouracil and folinic acid and cisplatin. In adenocarcinoma the same protocol contained no bleomycin. Drugs were infused for a 48 hours period in continuous infusion. The dosages were the same than in the intravenous regimens. Twenty patients with pelvic recurrences were included in this retrospective study: six were uterine cancers, fourteen were colo rectal cancers and two had advanced stage uterine cancer. Pain decreased in 10/14 patients with ano-rectal cancer pre sacral recurrence. Partial response was observed in 12 patients. Complete secondary surgical resection was possible in 4/14 rectal cancers and 6/6 uterine cancer recurrences. Chemotherapy induced a pathological complete response in 4/6 uterine cervix carcinoma recurrences. These observations led to perform pelvic intra arterial chemotherapy as first line treatment of locally-advanced inoperable pelvic tumors: 11 uterine cancers and five ano-rectal cancers. The objective were: tumor reduction before radiotherapy or surgery, tumor sterilization, decrease tumor volume for better radiation dosimetry, increase the chance of organ-preservation. The observation of tumor reduction in this small number of patients does not allow to draw definite conclusions. However the introduction of intra arterial pelvic chemotherapy as first line treatment of inoperable pelvic cancer warrants further studies.
