Background: Mantle-cell lymphoma (MCL) is known to have a poor outcome, however, most patients present with advanced-stage disease. Little information is available on limited-stage MCL. Patients and methods: We retrospectively reviewed clinicopathological information on all patients with limited-stage MCL seen at the British Columbia Cancer Agency since 1984. Results: Twenty-six patients had low bulk (<10 cm) stage IA (12 patients) or IIA (14 patients) MCL. Initial therapy was involved-field radiation therapy (RT) with or without chemotherapy (CT), 17 patients; CT alone or observation, nine patients. Fifteen patients are alive at a median follow-up of 72 months (range 14–194). Pro-gression-free survival (PFS) at 2 and 5 years was 65 % and 46%, and overall survival (OS) 86 % and 70%, respectively. Five patients surviving beyond 8 years. Only age and initial use of RT significantly affected PFS. Five-year PFS for patients <60 years of age was 83%, compared with 39 % for those aged ≥60 years, P = 0.04. Patients receiving RT with or without CT (n = 17), had a 5-year PFS of 68%, compared with 11 % for those not receiving RT (n = 9, P = 0.002). Receiving RT eliminated the impact of age on PFS (with RT the 5-year PFS was 83 % for those aged <60 years and 57 % for those ≥60 years, P = 0.17). Although OS for the whole group was 53 % at 6 years, it was 71 % for those initially treated with RT, but only 25 % for those not given RT (P = 0.13)
