This week's artwork was donated by Lonny, a pediatric cancer patient who received treatment at The Children's Hospital of Philadelphia . SO - International Congress of Radiation Oncology 1993. Results were discussed according to the technique of irradiation. Fourteen necroses have been observed necessitating APR in 5 cases, a definitive colostomy in 1 case.
Radiation therapy remains the reference treatment in anal canal carcinoma.
Neoadjuvant or concomitant chemotherapy have to be evaluated in randomized trials. Increased normal tissue damage with delayed healing was a severe problem in each patient. This led to prolonged delays in delivering an adequate dose of radiotherapy to the site of disease. Reasons for this are explored and suggestions made for the treatment of such patients in the future. The authors precise the present view about pathological, epidemiological, clinical and therapeutical aspects of these lesions.
