High grade soft tissue sarcoma arising in the popliteal space, axilla, and antecubital fossae (flexor fossae tumors) have by convention been classified as extracompartmental tumors by the accepted staging and grading criteria of the Musculoskeletal Tumor Society (MSTS). Advances in neoadjuvant chemotherapy and radiation therapy have made surgical resection more feasible. The hypothesis to be tested is that compartmental status may not be of prognostic significance if the tumor is adjusted for size, histologic grade, and distant metastasis after undergoing adjuvant chemotherapy and radiation. ⋯ Flexor fossae sarcomas do not have a poorer prognosis than extremity intracompartmental tumors when adjusted for size, distant metastasis, and histologic grade when they are treated with adjuvant radiation therapy, chemotherapy, and surgery.

Lymphokine-activated killer (LAK) cell function can be generated in peripheral blood mononuclear cells (PBMC) after brief exposure of high dose interleukin-2 (IL-2) over the course of 1 or 2 days' culture in plain culture medium (IL-2-pulsed PBMC). The aim of the present study was to investigate the ability of granulocyte-macrophage-colony stimulating factor (GM-CSF) to augment LAK induction in low dose IL-2-pulsed PBMC derived from patients with cancer undergoing immunotherapy with IL-2. ⋯ The use of GM-CSF for the enhancement of IL-2-induced LAK activity in 1 hour cultures may improve clinical results in cancer immunotherapy. In addition, implementation of this procedure could eliminate the high cost of cell culture which usually accompanies IL-2/LAK cell therapy as well as eliminate the known toxic side effects associated with this kind of therapy.

This survey documents the strategies used by pain control physicians in the selection of opioid drugs and routes of administration in the management of inpatients referred to a cancer pain service. ⋯ These data illustrate the application of strategies for selections of opioid drugs and their route of administration that are recommended in current guidelines for the management of cancer pain.
