Results of Surgical Treatment of Uncomplicated Colon Cancer. Case Series with Follow-Up

The standard treatment of colonic cancer (CC) continues to be the radical resection of the intestinal segment compromised with free margins, associated or not with adjuvant therapies. The aim of this study was to determine postoperative morbidity (POM) and 5-year overall survival (OS) in patients with uncomplicated colon cancer surgically treated. Retrospective case series of patients with uncomplicated CC undergoing colectomy and lymphadenectomy, consecutively, at Clinica Red Salud Mayor Temuco, between 2007 and 2019. The outcomes variable were POM and 5-years OS. Other variables of interest were surgical time, number of resected lymph nodes, hospital stay and recurrence. Descriptive statistics was used (measures of central tendency and dispersion), and OS analysis was applying Kaplan Meier curves. In this study, 52 patients (53.8 % men) were intervened, with a median age of 68 years. The most frequent localization and stages were right colon (42.3 %);IIIA and IIIB respectively (78.9 %). Median surgical time, number of resected lymph nodes and hospital stay were 98 min, 34 and 4.5 days respectively. POM was 17.3 % (9 cases). With a median followup of 58 months, a recurrence of 19.2 % was verified, and the 5-year OS for stages IIA, IIIA, IIIB and IVA was 83.3 %, 73.6 %, 68.2 % and 40.0 % respectively. The results, in terms of POM, mortality and 5-year OS, were similar to national and international series.

El objetivo de este estudio fue determinar morbilidad postoperatoria (MPO) y supervivencia actuarial global (SVAG) a 5 anos en pacientes resecados por CC no complicado. Serie de casos con seguimiento, de pacientes con CC no complicado, sometidos a colectomia subtotal y linfadenectomia, de forma consecutiva, en Clinica Red Salud Mayor Temuco, entre 2007 y 2019. Las variables resultado fueron MPO y SV actuarial global (SVAG) a 5 anos. Otras variables de interes fueron: tiempo quirurgico, numero de linfonodos resecados, estancia hospitalaria y recurrencia. Se utilizo estadistica descriptiva, con medidas de tendencia central y dispersion;y analisis de SV con curvas de Kaplan Meier. Se intervinieron 52 pacientes (53,8 % hombres), con una mediana de edad de 68 anos. La localizacion y estadios mas frecuentes fueron colon derecho (42,3 %);IIIA y IIIB respectivamente (78,9 %). La resecabilidad de la serie fue 100 %. La medianas del tiempo quirurgico, del numero de linfonodos resecados y de estancia hospitalaria;fueron de 98 min, 34 y 4.5 dias respectivamente. La MPO fue 17,3 % (9 casos). Con una mediana de seguimiento de 58 meses, se verifico una recurrencia de 19,2 %;y una SVAG a 5 anos para los estadios IIA, IIIA, IIIB y IVA;de 83,3 %;73,6 %;68,2 % y 40,0 % respectivamente. Los resultados obtenidos, en terminos de MPO, mortalidad y SVAG a 5 anos, fueron similares a series de nacionales e internacionales.
