A patient with colorectal cancer with bleeding may have a longer duration of bleeding if have been pointed out hemorrhoids, because he thinks that the source of the bleeding is a hemorrhoid. We compared symptom duration and survival rates of patients in whom hemorrhoids had been pointed out with those of patients without hemorrhoids in patients with colorectal cancer with bleeding. The mean duration of bleeding in the patients with hemorrhoids (7.9 months) was longer than that in the patients without hemorrhoids (5.2 months). The duration of bleeding in 52.9% of the patients without hemorrhoids was less than three months and 29.6% of the patients with hemorrhoids has the symptom for less than three months. In patients with stage I and II cancer who complained of bleeding via the rectum, the three-year survival rate for patients who had had the symptom for less than three months (85.7%) was significantly better than that for the patients who had had the symptom for more than three months (49.8%). In patients with stage III, IV, V, the survival rate for patients who had had the symptom for less than three months (75.9%) was also significantly better than that for the patients who had had the symptom for more than three months (32.4%). Although previous reports stated that the survival rate was not correlated with the duration of symptoms in colorectal cancer, our study demonstrats that in patients with colorectal cancer with bleeding the shorter clinical history could be associated with better survival rate.
