[Extended surgical resections of locally diffuse colorectal carcinoma (clinical cases)]

The authors report on a study population of extended operations for locally spread colon-rectum cancer in the Verona Surgical Clinic over the period from 1971 to 1987 (114 surgical demolitions for colon-rectum cancer out of a total of 1294 operations). They report an overall 5-year survival rate of 41% and a 3-year survival rate of 59% with a perioperative mortality rate of 1.75%. A number of aspects of such extended operations are discussed, and, in accord with most other reports in the literature, the authors confirm the validity of the choice of this type of surgery.
