Background:
This study aims to perform a survey on clinical data, sociodemographic and risk factors from patients with sporadic colorectal cancer (SCRC) treated between 2004 and 2008 in the Coloproctology Service of a teaching hospital in the North-western region of São Paulo.
Methods:
We analyzed 749 medical records. Of these, 460 were from colon cancer patients and 289 from rectal cancer patients. Most of the individuals had white skin and were aged over 62 years. The variables that were analyzed included gender, age, skin color, professional occupation, alcohol drinking and cigarette smoking, family history of cancer, and comorbidities. The identification of the clinical-sociodemographic profile and risk factors in a population with the SCRC the northwest region of São Paulo was performed to collaborate with prevention strategies.
Results:
The occurrence of SCRC did not differ much between genders. The most prevalent professional occupations were those related to household chores, agricultural and commercial activities. Among the comorbidities, hypertension and cholelithiasis were the most representative. The most common diagnosis method and treatment for the majority of patients were coloscopy and surgery, respectively. On average, the time of the disease progression was eight months. The median number of lymph nodes excised ranged between 11 and 14. The most common metastasis was hepatic.
Conclusion:
The occurrence of colorectal cancer is more frequent in men's white skin with aged over 62 years. Professional occupation seems to be more important for those exposed to carcinogenic agents. This type of tumor mostly affects the distal regions of the colon and rectum with the occurrence of liver metastasis. The affected individuals usually have low survival due to its high aggressiveness.
