Abstract:
The aim was to see if multidisciplinary care changed outcome in anal canal cancer. Treatment modalities and results of anal canal cancer were compared between the periods 1976-1980 and 1981-1990. In these periods there was a total of 23 patients (pts) seen, 7 of them in 1976-1980 and 16 in 1981-1990. HIV infected pts were excluded. There has been a recent increase in HIV-infected pts with anal canal cancers and lymphomas and these carry a poorer prognosis. Perianal and anal canal warts were often associated with this malignancy. Pts with these conditions should be monitored carefully for malignant changes. For the first group of pts there were 5 females, and 2 males who had abdominoperineal resection with colostomy, with 1 survivor. In the second group, 8 out of 16 pts were female. In the second decade, combined chemotherapy (5FU and mitomycin C) was given for 5 days at onset of 5 wk of radiation therapy. Biopsy was performed 1 mo after completion of radiotherapy. If positive, radical surgery and colostomy were done. If biopsy was negative, one more course of 5-day chemotherapy was given and surgery was avoided. In the 1- to 10-yr follow-up, there were 10 survivors free of cancer in the 16 pts (60%). This combined chemotherapy and radiotherapy protocol has changed the management of this rare malignancy.
