[Colorectal cancer. Location dependent symptoms?].
It is claimed that the symptoms of cancer in different parts of the colorectum are varied. The aim of the study was to decide how well the "classical" symptoms are divided between left and right colonic and rectal adenocarcinomas. This was a retrospective study of 102 patients with colorectal cancer at Ullevål hospital in 1992. Red blood in the faeces (p = 0.001), and changes in stool pattern (p = 0.001), were left colonic and rectal cancer specific. Moreover tenesmus, mucous stools, and pain at defecation were specific of rectal cancer. All these findings agree with the textbooks. Melaena, diarrhoea (p = 0.23), weight-loss (p = 0.09), a feeling of general physical weakness (p = 0.13), and ileus/subileus were not found as localisation specific symptoms, contrary to the claims of several textbooks. Pain was always correlated to the affected side in left and right colonic cancer, while in rectal cancer the localisation of pain was non-specific, and it appeared rather often; (37%) in Dukes' A and Dukes' B. Only a few patients had anorexia, but the number was still significant for those with right colonic cancer (p = 0.04). With few exceptions, our results generally support the textbooks. The referring symptoms may help to decide the necessity for further examinations, when total colonoscopy is not obtained.
