The transfemoral approach of the UF insetion represents a significant simplication of the inferior vena caval interruption, but it can only be used if thrombi are excluded by venography in the iliac vein and inferior vena cava.

Recent reports of local tumor control in so-called \"radioresistant tumors,\" such as salivary gland tumors, adenocarcinomas of the breast, prostate and pancreas, malignant melanoma and malignant carcinoid, are summarized. Current status of heavy particle radiotherapy is discussed in detail. Results of initial clinical trials of neutron beam therapy are summarized, and a brief review of proton beam clinical trials and pion beam facilities is included. Recent reports defining the role of combined irradiation and surgery in rectal and breast cancer, and in soft tissue sarcomas, are discussed. Reports of enhanced radiation toxicity seen with concomitant or sequential chemotherapy and radiotherapy are detailed, including CNS toxicity seen with methotrexate and cytosine arabinoside, cardiotoxicity with adriamycin, and pulmonary toxicity with bleomycin.
