• Radiation-associated small bowel injury occurs in up to 50% of patients receiving postoperative radiotherapy following pelvic cancer surgery. We describe our experience using a biodegradable mesh that allows the small bowel to be supported above the pelvic inlet and is totally absorbed following radiation therapy. Between 1985 and 1989, 45 procedures were performed in patients with carcinoma of the rectum (anterior resection in 15 patients, abdominoperineal resection in 23 patients, pelvic exenteration in six patients, and proctocolectomy in one patient). In 30 patients a polyglycolic acid (Dexon) mesh was used, and in 15 patients a polyglactin 910 (Vicryl) mesh was used. Forty-four patients received postoperative radiotherapy. The mean (± SEM) dose was 56.8 ± 18.4 Gy. There were no immediate complications related to the mesh. Follow-up ranged from 12 to 53 months (median follow-up, 34 months). With the exception of two patients who had a polyglactin 910 mesh and who developed bowel obstruction due to adhesions under the anterior abdominal wall, there has been no documented incidence of clinical radiation-associated small bowel injury. The use of the absorbable mesh may permit us to use higher doses of postoperative radiotherapy without the associated hazard of radiation-associated small bowel injury.

Combined therapeutic regimens integrating chemotherapy, radiation therapy, and surgery are reported to be effective in treating advanced squamous cell carcinomas of the head and neck. The current study evaluates 58 consecutive patients with advanced (T4, N3) head and neck cancers. Forty patients (multimodal group) were treated with 2 courses of chemotherapy (cisplatin 2 mg/kg; methotrexate 280-560 mg/m2 with leucovorin rescue; bleomycin 30 mu X 3) followed by radiation therapy and surgery. Eighteen patients (combined group) were treated with preoperative radiation therapy followed by surgery. In the multimodal group there were 27 (67.5%) partial responses and nine (22.5%) complete responses, for an overall response rate of 90%. Response rates by site of primary lesion were: oral cavity, 11 of 11; oropharynx, 13 of 17; hypopharynx, 5 of 5; and larynx 7 of 7. Distant metastases (skin, lung, bone, central nervous system [CNS]) appeared in 16 patients (40%) (P less than 0.05 versus combined) at a median time of 8.5 months after diagnosis, 15 in patients having a partial (11) or complete (4) response. Thirteen patients (33%) developed distant metastases within 1 year of diagnosis (P less than 0.05 versus combined). In 11 of these patients, the primary lesion and neck disease were resectable. Two thoracotomies were performed for solitary pulmonary metastases; one was resected for cure. Fifteen patients (38%) underwent curative resection; 11 (73%) were alive at 1 year, and ten (67%) were free of disease. Overall survival was 20 of 40 (50%) at 1 year. In the combined group, there were 14 partial responses (78%) and no complete responses. Early distant metastases appeared in two patients (12.5%), at 2 and 6 months after diagnosis. Seven patients (38%) underwent curative resection; six of seven (86%) were alive at 1 year, four of seven (57%) were disease-free. Six of 16 patients at risk (37.5%) survived 1 year. After combined therapy, six of ten patients (60%) with responses to therapy survived 1 year versus 12 of 20 responders (57%) without distant metastases in the multimodal group. It is concluded that multimodal therapy for advanced head and neck cancer results in a higher response rate than with conventional combined therapy. The incidence of early and postoperative distant metastases was increased after the multimodal regimen. At 1 year there were no differences in survival between the combined and multimodal groups for responders without early metastases. Further observation is needed to determine the net long-term effects of this regimen. A prospective randomized comparison of combined and multimodal therapy for advanced lesions is indicated.

Voice rehabilitation is a major problem after laryngectomy. A new method to construct a pseudolarynx after total laryngectomy by suturing the trachea to the hyoid bone is described. The surgical technic is relatively simple. Patients are able to speak in the immediate postoperative period without intensive therapy. The quality of speech is good. Aspiration of liquids is a common problem, but in time patients learn to swallow with minimal or no aspiration. This procedure could be utilized in selected cases for good voice rehabilitation after total laryngectomy.

Skin grafts are an important component in immediate reconstruction after extensive resection in the head and neck region. Edgerton [I] has written extensively on their use in the area of the laryngopharynx, and others [2,3] have remarked on their effectiveness in lining the tonsillar area, palate, and tongue. Most of the patients we treat with Tesions in the higher clinical stages have received 6,000 r of cobalt radiation prior to operation. Originally, we were reluctant to use skin grafts in the radiated areas and attempted to draw the structures together for primary closure wherever possible. Patients with carcinoma of the maxilla were an exception to this rule. Part of the repair in these patients for years has been the immediate lining of the defect with a split thickness graft [4]. These grafts usually take well despite high doses of preoperative radiation. Encouraged by this, we began to use skin grafts to cover extensive areas of postradiation resection in the laryngopharynx and oropharynx.

From the Tumor Registries of the East Orange, New Jersey, Veterans Administration Medical Center, and the College of Medicine and Dentistry of New Jersey/New Jersey Medical School, 1,066 cases of head and neck cancer were reviewed. Blacks comprised 32% of the population reviewed. Charts of 70 patients, 45 years old or younger, were examined. Seventy percent of this group was black. At diagnosis, the proportion of patients 45 years old or younger was 14% for blacks and 2.9% for whites, a significant difference (P less than 0.001). Seventy-six percent of lesions in black patients and 86% in white patients were situated above the hypopharynx. Sixty-one percent of all patients 45 years old or younger had Stage III or IV lesions when first diagnosed, regardless of race. Black-to-white survival rates were 23 to 40% after 2 years, and 5 to 13% for those at risk after 5 years. Prognosis is poor for younger patients, in general, and worse for young black patients than for whites.

Twelve patients with advanced locoregional (Stage III and IV) squamous cell carcinoma of the oral cavity and oropharynx underwent treatment with cisplatin, vinblastine, bleomycin, and 5-fluorouracil, given by intra-arterial infusion, as primary adjuvant therapy, in preparation for radiation therapy and surgery. Responses were observed during or immediately after infusion therapy in 8 of 12 (67%) of patients (1 complete response, 7 partial responses). Infusion chemotherapy was followed by radiation therapy alone in five patients and by radiation and surgery in six patients. The protocol was initiated in August 1981, and six patients are now free of their primary cancer, at 21 to 36 months, whereas six have died with disease. Arterial infusion of a combination of effective antineoplastic agents is a promising method for the preparation of selected patients for radiation therapy and surgery, as it is less likely to produce serious systemic toxicity and it requires a shorter period than systemic neoadjuvant chemotherapy.

The use of cervical flaps for immediate reconstruction after operation in twenty-one patients in whom the neck received 4,000 to 6,000 r six weeks prior to operation is reported. Successful repair was achieved in a majority of these patients. We conclude that such flaps can be safely used in most instances, assuming they are designed to achieve maximum blood supply or are in an area that received minimal radiation exposure. We recommend this approach only when the radiation given is part of a course of previously planned, integrated therapy combining radiation and operation and when the major portion of the flap has not been exposed to more than 4,000 r.

Thyroidectomy initiated by transecting the isthmus and peeling the lobes laterally away from the midline exposes the three vital elements of thyroid anatomy, namely the vessels, the recurrent laryngeal nerves and the parathyroid glands, by an almost bloodless dissection conducted at a distance from these vital structures. Part or all of the lobe or lobes can be removed while the parathyroid glands and recurrent laryngeal nerves remain clearly under view at all times.

Summary One hundred sixteen penetrating wounds of the neck were seen at the Martland Hospital-New Jersey Medical School. Sixty-two per cent of the patients had one or more major structural injuries. Forty-three per cent of the patients without major organ damage had clinical findings to indicate immediate surgery. The mortality was 3.5 per cent. Gunshot wounds are potentially more lethal and merit particular care and aggressive therapy. From the experience in this series, we are convinced that immediate exploration of all penetrating neck wounds is the safest means of management.
