Surgical and adjuvant radiation therapy of resectable retroperitoneal soft tissue sarcomas in adults.

Primary soft tissue sarcoma of the retroperitoneum is a rare disease. A series of 11 evaluable adult patients with retroperitoneal soft tissue sarcomas is reported. These patients were treated with complete surgery and adjuvant radiation therapy (total dose from 50 to 64 Gy) using an 18 MeV linear accelerator. After a median follow-up of 48 months (range, 6-84), 4 patients had a local-regional recurrence, 3 had distant metastases, and 4 died of progressive disease. Four-year estimated disease-free survival was 54.5% and overall survival was 70%. Treatment was well tolerated by most patients: 7 patients experienced moderate gastrointestinal toxicity, mainly nausea and diarrhea, during radiotherapy; 2 cases had weight loss > 15% at the end of the therapy; and chronic ileitis was observed in 2 cases. We conclude that adjuvant radiotherapy seems to reduce the incidence of local-regional recurrences in these patients. No radiation-induced irreversible injury was observed, but one young woman had amenorrhea after radiotherapy. Controlled clinical trials are warranted to define the role and effectiveness of adjuvant radiotherapy and/or chemotherapy in retroperitoneal soft tissue sarcomas.

A distinctive aphthous ileitis linked to Ancylostoma caninum.

Ileal ulceration is diagnosed commonly at colonoscopy in northeastern Australia. This observation has occurred contemporaneously with the description of a painful enteritis caused through supposedly rare infections by Ancylostoma caninum, the cosmopolitan dog hookworm. In this study, we describe the morphology and prevalence of ileal ulcers and investigate their cause. There were 182 patients with a distinctive aphthous ileitis highlighted by haemorrhage into the tips of surrounding villi. The annual rate reached 4.7% of ileal examinations. Eosinophilic enteritis was the characteristic, but inconsistent, histological appearance. Ulceration was linked to infection by A. caninum through serological testing and, in three patients, by the retrieval of single hookworms. Affected patients were also more likely to own a dog (53%) than the total colonoscopic population (43%; P < 0.02). The monthly rates of diagnosis were related to climate with fewest recordings during winter. Pain was the chief indication for colonoscopy (49%), proportionally higher than in controls (28%; P < 0.0001). Patients with ulcers had increased blood eosinophil, immunoglobulin E and serological values. These results were higher still in the subset with pain compared with the rest. Most patients, however, had colonoscopy performed for unrelated reasons, such as bowel cancer surveillance, and were identified as having subclinical ulceration (rate 3.2%). The findings establish a distinctive aphthous ileitis characterized by tissue eosinophilia. The cause has been tentatively linked to canine hookworms. It is proposed that infection in this geographic region is common and only rarely does a painful enteritis develop as a consequence of hypersensitization.

Regional enteritis with major gastrointestinal hemorrhage as the initial manifestation.

Four patients with massive gastrointestinal hemorrhage were found to have Crohn's ileitis. This prompted a five-year chart review of consecutive admissions for Crohn's enteritis; 60 patients were found whose disease was limited to the distal part of the ileum (and rarely the proximal part of the cecum). Eight (13%) of these patients were admitted because of major rectal bleeding, and in seven of the eight the hemorrhage was the initial manifestation of Crohn's disease. The mean age of the entire group was 30 years, with a mean age of 18.6 years in the eight bleeders. Crohn's ileitis should be considered in the differential diagnosis of massive rectal bleeding, especially in younger patients.
