Hemangiopericytoma is a rare soft tissue tumor with unpredictable biological behavior and with a high local recurrence rate. Wide surgical excision of all lesions, whenever feasible, should be the treatment of choice.

During a 20-year period, 77 patients who underwent ligation of the common or internal carotid artery were analyzed for the site, side of hemorrhage and/or ligation, with incidence of rebleed, previous treatment (surgery and/or radiation therapy), the type of incision utilized for resection, the incidence of preoperative and intraoperative hypotension and hemiplegia. The immediate mortality and subsequent follow-up of the patients were also noted.

A retrospective review of 832 patients with squamous cell cancer of the head and neck between 1961 and 1985 was carried out to determine the incidence of multiple primary cancers (MPC) at the time of autopsy and the number who died of the second cancer. The overall risk of developing a second MPC of the head and neck, lung, or esophagus from treatment of first head and neck cancer to time of autopsy was 4.04% per year.

From January 1960 to December 1977, 61 patients had a simultaneous one-stage bilateral neck dissection with or without excision of the primary lesion, while 63 patients had a therapeutic second (two stage) neck dissection performed by our service. In ten patients, one or both of the internal jugular veins and spinal accessory nerve were preserved. Patients in both groups were staged, using the American Joint Commission 1977 clinical classification. All the pathologic specimens had lymph node clearance done. Simultaneous bilateral neck dissection, in the present study, has an operative mortality of 10%, with 11% life-threatening complications and with 62% significant postoperative facial swelling. There is an overall three- and five-year survival rate of 20% and 12.5%. Patients who had bilateral staged neck dissection had complications seen in 54%, with a 3.2% mortality rate. The overall three- and five-year survival in this group of patients was 60% and 38%, respectively.

Sixty-nine patients were entered in a randomized study to determine the usefulness and practicality of parenteral hyperalimentation (TPN) in preparing and supporting patients with head and neck cancer undergoing radical resections. The patients were stratified by nutritional status and prognosis and randomization were done within each strata to TPN or control. Minimum full TPN was given at 35 calories/kgm/day for at least 14 days postoperatively. Eight patients received preoperative TPN also. Control patients received customary enteral alimentation by feeding tubes. Under the conditions of this particular study, the administration schedules, and type of solutions used, we were unable to demonstrate any superiority of TPN over conventional enteral nutrition in terms of immune parameters, wound healing, complications, and survival.
