in 4 cases. All 17 patients in group 1 and 6 of 8 in group 2 achieved a complete response, but 10 experienced relapse in the skin (n=8), the skin and lymph nodes (n=1), or the central nervous system (n = 1). Four patients had multiple successive cutaneous relapses. Treatment of relapses included surgery (1 case), radiotherapy (4 cases), rituximab (1 case), ibritumomab tiuxetan (1 case), and/or various chemotherapies (4 cases). No patient was lost to follow-up. After a 33-month median follow-up, 20 patients were alive (including 13 in complete remission), 3 had died of lymphoma, and 2 had died of unrelated causes. The 3-year disease-specific survival rate was 87%.Nine patients (36%) had at least 1 grade 3 or higher adverse event, including grade 3 (n=2) or grade 4 (n=5) neutropenia, grade 4 thrombocytopenia (n = 1), grade 4 neutropenic sepsis (n=1), grade 3 cardiac failure (n=1), grade 3 pneumonia (n = 1), and grade 3 venous thrombosis (n=1; this patient had a catheter). One patient died of neutropenic septicemia.These 25 patients treated with R-PCT were compared with a historic series of 47 patients with PCLBCL-LT who received other therapies only, as detailed in a previous study. 2 The 2 groups did not differ by classic prognostic factors, 2 including age (median ages, 76 vs 78 years) (P=.30), location of skin lesions, clinical stage at diagnosis, performance status, or lactic dehydrogenase level. However, the percentage of patients who achieved a complete response (92% vs 64%) (P=.01) and the 3-year specific survival rates (87% vs 50%) (P= .004) were much higher in patients treated with R-PCT.
