[Surgery and adjuvant therapy of cancer of the large intestine].
The postoperative survival rate after radical surgery for large intestinal cancer shown to be differentiated adenocarcinoma is relatively good. However, the effect of surgical adjuvant therapy on this cancer is considered to be the least promising. 5-FU, FT-207, MMC, ADR and VCR are used for chemotherapy and OK-432, PSK, BCG, levamisole and lentinan are also used as forms of immune therapy. There are no significant differences in the statistics used for comparison with controls as to the effects of these adjuvant therapies. A more intensive regional therapy has therefore been adopted for local recurrence of rectal cancer and liver metastasis of colon cancer considering the form of postoperative cancer recurrence. MMC was injected into the superior rectal artery for rectal cancer and into the portal vein during surgery for colon cancer in the 1st program of research of the Kajitani group. However, the efficacy of these procedures was not proved. Although immune therapy with OK-432 has also been subsequently added in the second research program, no efficacy was apparent. Taylor and Birmingham have reported that liver metastasis was remarkably decreased by continuous infusion of 5-FU through the portal vein. There is also a report by GITSG in the USA that a reduction of local recurrence was obtained by combination of 5-FU and Me-CCNU with irradiation treatment after surgery for rectal cancer.
