MONTES DE OCA MEGIAS, Elizabeth et al. Behavior of sporadic colorectal cancer in a provincial hospital. Rev cubana med [online]. 2012, vol.51, n.4, pp.302-312. ISSN 0034-7523.

Introduction: the colorectal cancer holds the second place among the malignant neoplasias worldwide and its incidence is growing. The Cuban Statistical Annals of 2011 reported 2 039 new cases. The prognosis depends on early diagnosis. Objective: to describe the behavior of the colorectal cancer. Methods: a cross-sectional study was made in "Manuel Ascunce Domenech" university hospital in Camagüey, Cuba, from January 2009 to December 2010. The sample was made up of 106 patients diagnosed by colonoscopy and biopsy. The surgical sample was subjected to the anatomical and pathological analysis. The data were taken from the primary register and processed in Windows-based SPSS system. Results: the number of cases raised as the age increased, males (53.8 %) and the patients without family history (91.5 %) or personal history (76.4 %) of this pathology predominated. Constipation (42.4 %) and rectal bleeding (33 %) were the most frequent manifestations of left colon tumors, whereas anemia (27.4 %) and palpable tumor (22.6%) were those of the right colon tumor. The highest percentage of tumors was located in the left colon (66.1 %); the polypoid variety (59.4 %) and adenocarcinoma (97.2 %) prevailed. The staging B accounted for 62.3 % of cases according to Dukes' classification. Conclusions: these results agree with the international trends. The colorectal cancer continues to be identified at advanced stages, so the implementation of screening strategies to reduce the incidence and the mortality rates must be considered.
