RESUMEN
Angiosarcomas of the female genital tract are rare and primary angiosarcoma of the cervix is extremely rare with only one prior case report. We report a case of a primary cervical angiosarcoma in a 43-yr-old woman who presented with heavy vaginal bleeding. Cervical biopsy and subsequent radical hysterectomy showed a malignant vascular tumor which was composed of spindled and epithelioid cells and formed abortive vascular channels. Immunohistochemically, the tumor cells were diffusely positive for CD31, CD34, ERG, and cyclin D1 and focally positive for D2-40. A reverse transcription polymerase chain reaction test for YWHAE-NUTM2 genetic fusion was negative excluding a YWHAE-translocated high-grade endometrial stromal sarcoma. The tumor formed a 5 cm mass within the cervix with microscopic involvement of the endometrium, superficial myometrium, and vagina. Metastatic microscopic tumor deposits were present in both ovaries, left fallopian tube, one paracervical lymph node, and one pelvic lymph node. In reporting this unusual case we discuss the differential diagnosis.

BACKGROUND: Gastrointestinal (GI) hormones regulate several GI functions, including the proliferation and repair of normal mucosa, and hormone receptors may therefore be implicated in the growth, invasion, and metastasis of cancers of the GI tract. The aim of this study was to determine the cellular distribution of gastrin in intestinal-type gastric cancers, and to determine its relationship to outcomes after R0 gastrectomy. METHODS: Eighty-six consecutive patients undergoing R0 gastrectomy for adenocarcinoma were studied. Normal gastric mucosa and tumor were stained for gastrin and their specific cellular distribution was determined. RESULTS: The duration of survival of patients whose tumors exhibited well-differentiated gastrin-positive tumor (GPT) cells (n = 12) was significantly poorer than that of patients whose tumors were GPT-negative (5-year survival, 30% vs 54%; P = 0.037). Patients with GPT-positive intestinal-type gastric cancer (5 of 47 patients) had the poorest survival of all (median, 14 months; 5-year survival, 0%; P = 0.006). In a multivariate analysis, only lymph node metastases (hazard ratio [HR], 2.13; 95% confidence interval [CI], 1.2 to 3.79; P = 0.01) and the presence of GPT cells (HR, 6.61; 95% CI, 1.74 to 25.09; P = 0.01) were independently and significantly associated with durations of survival in patients with intestinal-type gastric cancer. CONCLUSION: The presence of GPT cells in patients with gastric adenocarcinoma is a significant and independent prognostic indicator.

BACKGROUND: To determine the role of body mass index (BMI) in a Western population on outcomes after modified D2 gastrectomy (preserving pancreas and spleen where possible) for gastric cancer. METHODS: Eighty-four consecutive patients undergoing an R0 modified D2 gastrectomy for gastric cancer were studied prospectively. Male patients with a BMI of greater than 24.7 kgm(-2) and female patients with a BMI of greater than 22.6 kgm(-2) were classified as overweight and compared with control patients with BMIs below these reference values. RESULTS: Thirty-eight of the patients (45%) were classified as overweight. The median BMI of the overweight patients was 27.0 kgm(-2) (range, 22.7-34.7 kgm(-2); 27 males) compared with 21.2 kgm(-2) (range, 15.2-24.7 kgm(-2), 31 males) for control patients. Operative morbidity and mortality were 26% and 7.9% in overweight patients compared with 22% and 6.5% in control patients (morbidity, chi(2) = 0.240; df = 1; P = 0.624; mortality, chi(2) = 0.059; df = 1; P = 0.808). Cumulative survival at 5 years was 52% for overweight patients compared with 55% for control patients (chi(2) = 0.15; df = 1; P = 0.7002). In a multivariate analysis, the number of lymph node metastases (hazard ratio, 1.441; 95% confidence interval [CI], 1.159-1.723; P = 0.009) and splenectomy (hazard ratio, 12.111; 95% CI, 9.645-14.577; P = 0.043) were independently associated with the duration of survival. CONCLUSION: High BMIs were not associated with increased operative risk, and longterm outcomes were similar in the two groups after modified D2 gastrectomy.
