Anal canal cancer and chemoradiation treatment in two patients with systemic lupus erythematosus treated by chronic therapeutic immunosuppression.

Abstract

Two case reports of anal cancer developing during chronic therapeutic immunosuppression for systemic lupus erythematosus (SLE) and their cancer management are presented. The complex issues of delivery of curative chemoradiation treatment for anal cancer in the context of co-existing autoimmune connective tissue disease (AICD) are discussed. These two cases show that combined chemotherapy and radiation regimens are possible in patients with SLE. However, frequent, careful assessment with judicious and prompt management of haematological and other complications during treatment is important.
