Tumors of the angle of Treitz: a single-center experience.
OBJECTIVE
To explore the feasibility and oncologic outcomes of segmental jejunal resection on the left side of the mesenteric vessels in patients with tumors of the angle of Treitz using data from a single center.


METHODS
Thirteen patients with tumors of the angle of Treitz who underwent surgery at our institution were prospectively followed. A segmental jejunal resection on the left side of the mesenteric vessels was performed in all patients. Formalin-fixed and paraffin-embedded tumor samples were examined. The primary end point of this analysis was disease-free survival.


RESULTS
In this study, there were 8 males and 5 females (mean age, 50.1 years; range, 36-74 years). The mean tumor size was 8.1 cm (range, 3.2-15 cm). Histologic examination showed 11 gastrointestinal stromal tumors (GISTs) and 2 adenocarcinomas. Five of the GIST patients presented with potential low risk, and 6 presented with intermediate and high risk, according to the National Institutes of Health criteria. One potentially high-risk patient showed tumor progression at 46 mo and died 52 mo after surgery. One patient with locally advanced adenocarcinoma received neoadjuvant chemotherapy and adjuvant radiotherapy, but the disease progressed, and the patient died 9 mo after surgery. One GIST patient without progression died 16 mo after surgery because of a postoperative intestinal obstruction. The median overall survival rate was 84.6 mo, and the median disease-free survival rate was 94.5 mo.


CONCLUSIONS
The overall survival of patients with tumors of the angle of Treitz was encouraging even when the tumor size was relatively large. A segmental resection on the left side of the mesenteric vessels is considered to be a reliable and curative option for tumors of the angle of Treitz.
