RESUMO

Objetivo: Presentar la experiencia preliminar en el tratamiento de la carcinomatosis peritoneal de origen gastrointestinal y ginecológico. Métodos: El estudio incluye 11 pacientes portadores de carcinomatosis, tratados por medio de citorreducción y quimioterapia hipertérmica intraoperatoria y operados entre enero del 2005 y enero del 2008. Resultados: La mediana de edad de los pacientes fue de 50 años (rango = 22-56) y pertenecieron al sexo masculino el 54.5%. La mediana de duración del procedimiento citorreductivo fue de 630 min (rango 205-840). La citorreducción completa fue obtenida en el 54,6% (6/11) de los pacientes. La mediana de órganos resecados por paciente fue 4 (rango = 2 - 5) y la mediana de peritonectomia por paciente fue de 3 (rango = 0-6). Las drogas utilizadas para el baño hipertérmico fueron la Mitomicina C en las carcinomatosis por cancer de colon y del apéndice y el Cisplatino en carcinomatosis por cáncer de ovario. El tiempo d irrigación fue de 90 min y la mediana de la temperatura alcanzada fue de 41º C (39ºC - 43ºC). La mortalidad posoperatoria fue del 9,1% (1/11) y la morbilidad del 63,6% (7/11). La mediana de internación fue de 10 días (4-67), en los pacientes complicados la media de internación fue de 44 días para las severas y de 9 días para las leves. La supervivencia libre de tumor fue del 30% (mediana de seguimiento de 8,3 meses).

RESUMO

PURPOSE: This study was designed to assess the local recurrence rate and prognostic factors for local recurrence in patients undergoing curative anterior or abdominoperineal resections without radiotherapy. METHODS: From January 1980 to December 1996, 514 consecutive patients underwent curative resections for rectal cancer. We excluded those with preoperative radiotherapy (n = 23), postoperative radiotherapy (n = 27), local resection (n = 36), and 11 (2.1 percent) patients who died postoperatively. The remaining 417 patients (249 males) with a median age of 64 (range, 21-90) years were analyzed. For upper third lesions, mesorectal tissue was excised down to at least 5 cm below the tumor. Total mesorectal excision was performed for lower and middle tumors. Postoperative chemotherapy was limited to patients with Stage III lesions. Median follow-up (and 95 percent confidence interval) was (5.2 4.3-5.9) years, with 87.7 percent of patients followed up longer than 24 months. Local recurrence was defined as any recurrence within the field of resection, regardless of the presence or absence of distant metastasis. RESULTS: Five-year local recurrence rate(and 95 percent confidence interval) was 9.7 (6.4-13) percent, with a median time to diagnosis of 15 (10-23) months. Local recurrence rates in Stages I, II, and III were: 3.1, 4.1, and 24.1 percent, respectively (P < 0.0001). In relation to node status, local recurrence rates were N0, 4.1 (1.7-6.5) percent; N1, 12.6 (4.6-20.6) percent; N2, 32.1 (12.1-52.1) percent; and N3, 59.3 (22.5-96.1) percent; (P < 0.00001). Lower third tumors had a higher local recurrence rate than middle and upper third tumors: 17.9, 7.1, and 5.1 percent, respectively (P = 0.002). Adjusted by stage, this difference was maintained only in Stage III tumors. Among lower tumors, those at 6 and 7 cm from the anal verge had a lower local recurrence rate than those below 6 cm (6.7 vs. 26.2 percent, respectively; P = 0.02). Accidental rectal perforation at or near the tumor site occurred in 12 cases (2.9 percent), showing a strong correlation with local recurrence (P < 0.0001). Multivariate analysis showed significant higher risk for lower third tumors (hazard ratio, 2.98) and positive nodes (hazard ratio, 4.78). CONCLUSIONS: Appropriate surgery without irradiation achieves excellent local control in N0 rectal cancers. Node metastasis, lower third localization (especially below 6 cm), and accidental rectal perforation at or near the tumor site are significantly associated with a higher local recurrence rate.
