    Abstract

    The National Institutes of Health (NIH) held on a consensus conference which recommended 5-FU and levamisole as adjuvant chemotherapy for colon cancer MAC (Modified Astler Coller) stage C. From 1991-1994, 37 such patients diagnosed here were treated with 5-FU (intravenous dose of 450/mg/m2/d for 5 days and from day 29, once a week for 48 weeks) and oral levamisole (50 mg 3 times/d, for 3 days, every 2 weeks for a year), as suggested by NIH guidelines. 16 patients were males and 21 were females, mean age was 62 years and median 64. Cancer locations were: right colon (in 16, 43%), left colon (19, 51%), multiple colon primaries (2, 1%). 25 (68%) had 1-3 positive lymph nodes and 12 (32%) had 4 or more positive lymph nodes. Only 20 (54%) finished treatment as prescribed. In the others, 1 or both drugs caused side-effects for which the drugs had to be stopped. 6 patients relapsed while on treatment. The most common side-effects were diarrhea, stomatitis and bone marrow suppression. 3 were hospitalized due to neutropenic fever. 5-year actuarial survival of all patients was 61%; 5-year relapse-free survival of right versus left colon was 41% and 82%, respectively (p<0.01). There was no significant difference in 5-year survival of those with 1-3 positive lymph nodes as compared to those with 4 or more (62% and 56%, respectively). 5-year survival in those who finished or did not finish treatment (excluding those who stopped treatment because of progressive disease) was 83% and 70%, respectively (NS). The 5-year survival of our series was similar to that of patients treated similarly elsewhere. The 5-FU and levamisole treatment was not tolerated well by our study population. It has recently been replaced in our service by a 5-FU and leucovorin regimen given for 6 months.
