Abstract
Aims: In recent years, the optimum primary management of primary central nervous system lymphoma (PCNSL) has evolved from combined modality chemoradiotherapy to chemotherapy alone. We describe a single-centre case series of PCNSL with a view to assessing the role of radiotherapy in primary disease management. Materials and methods: West of Scotland PCNSL cases between 2001 and 2010 were identified by neuropathology. Observational data were collected retrospectively from case notes and electronic systems. Results: Forty-nine patients fulfilled the eligibility criteria. The median age was 61 years. Chemotherapy with a view to consolidation radiotherapy on completion was delivered to 61% (n = 30). Regimens varied, but were generally methotrexate-based. Chemotherapy was discontinued prematurely in 80% (n = 24) due to progressive disease (n = 12), intolerable toxicity (n = 7) or death (n = 4). In all patients who progressed or did not tolerate chemotherapy, treatment was changed to immediate salvage radiotherapy; modal irradiation was 40 Gy. Radiotherapy alone was delivered to those not suitable for chemotherapy (18%, n = 9) and best supportive care to those with poor performance status (18%, n = 9). The overall median survival was 8 months. In those receiving single modality radiotherapy or chemotherapy, the median survival was 5 and 8 months, respectively. For those completing chemoradiotherapy in its entirety, 3 year survival was 100%; in groups receiving salvage radiotherapy despite progressive disease or chemotherapy toxicity, moderate survival was maintained with immediate radiotherapy with 3 year survival rates of 33 and 60%, respectively. Conclusions: Although chemotherapy alone remains the optimal treatment of PCNSL, out with clinical trials only a minority of patients complete chemotherapy due to toxicity and disease progression; in such patients, immediate salvage radiotherapy provides an effective and safe alternative with maintenance of good outcomes.
