A 65-year-old woman with diabetes mellitus was hospitalized for heart failure and anemia in August 2001, and recovered with conservative treatment. An endoscopic examination revealed an ulcerative mass located in the duodenal bulb to the 2nd portion. Abdominal CT scan demonstrated tumor involvement in the pancreas head. The diagnosis of a diffuse large B-cell lymphoma, clinical stage IIE, was made by endoscopic biopsy. Although surgical resection of the localized intestinal tumor would have been a common choice for initial treatment, polychemotherapy was selected; the patient had diabetes mellitus and preferred polychemotherapy to surgical operation. Because of bulky intestinal mass, transmural disease and sensitive histological type, standard-dose chemotherapy was considered to include a high risk of intestinal perforation. We performed dose-escalating chemotherapy: A half dose of THP-COP (pirarubicin, cyclophosphamide, vincristine) was given at the start in October 2001, 60% THP-COP as the next cycle, 80% THP-COP as the 3rd cycle and thereafter. Without serious complications of the intestine, she received a total of 6 cycles of chemotherapy and subsequent involved field radiation. There has been no evidence of recurrence of disease 14 months from the start of chemotherapy. When conditions make surgical treatment difficult, dose-escalating chemotherapy in a treatment cycle may be considered as an alternative.
