IMPROVING THE SURGICAL RESULTS OF COLORECTAL CANCER

National Cancer Center Hospital, Tokyo Keiichi Hojo |
The incidence of cases of Dukes C stage has been reduced from 55% in 1962-1970 to 45% in 1971-1981.
Extended operation has been widely carried out and resulted in a decrease in the local recurrence and in increasing of cure rate, especially in the case of lower rectal advanced cancer.
To detect the recurrence early by postoperative periodical “follow-up” and to try surgical retreatments are also effective in some cases. We have a few patients who have survived more than 5 years after removing of the recurrent lesions of the liver or lungs by surgery.
Several programs of postoperative adjuvant chemotherapy, however, have been carried out and resulted in failure to get the good result.
To prevent the local recurrence in lower rectal advanced cancer and the liver metastasis in the colon cancer are the most urgent problems on the treatments of colorectal cancer in recent. By adopting the new treatment of multiple disciplinary procedures (surgery, irradiation, hyperthermia, chemotherapy and immunotherapy) and new stronger adjuvant chemotherapy for a group of patients who will be selected as a high-risk one of liver metastasis postoperatively by using the computer analysis based on the many clinical data, more improvement in the therapeutic result will be expected in near future.
