Abstract

Textile workers are known to have a high risk of developing colorectal cancer. The identification of the occupational risk factors for this cancer is therefore of great importance.

The study population, drawn from the personnel records of a textile plant, was composed of 43 cases of colorectal cancer diagnosed between 1965 and 1979, and controls with no cancer. Risk factors studied included the type of work performed, handling of various substances, length of work at each workstation, and lifestyle factors.

The results demonstrated a significantly increased risk starting in 1975 and particularly affecting workers exposed to polypropylene.

This study was the first to link exposure to polypropylene fibre extrusion with an increased risk of colorectal cancer. In the intervening period, other studies have demonstrated an association between exposure to polypropylene powder and increased risk. This study draws attention to the importance of medical follow-up in the early screening of exposed workers.
