Clinical and prognostic analysis of 30 cases of primary central nervous system lymphoma / 中华血液学杂志

<p><b>OBJECTIVE</b>To explore clinical characteristics， treatment and prognosis of primary central nervous system lymphoma(PCNSL).</p><p><b>METHODS</b>Retrospective analysis, Kaplan-Meier analysis and Log-rank test were conducted on 30 PCNSL patients from 2006 to 2014 in our hospital.</p><p><b>RESULTS</b>The median age of this cohort (14 males and 16 females) was 57.4 years old. 18 cases had single tumor, 12 cases multiple. 17 cases presentd with intracranial hypertension and 13 cases focal neurological deficits. 13 cases (62%) were diffuse large B cell lymphoma. About 60% patients received combination therapy including surgery, radiotherapy or chemotherapy. 63.3% complete remission rate (CR) was achieved for all patients. Kaplan-Meier analysis and Log-rank test showed the median overall survival (OS) was 24 months, the rates of 2-year survival, 5-year survival, 6-month progression-free survival(PFS) and 1-year free-progressed survival (PFS) were as of 46.7%, 13.3%, 60.0% and 43.3% respectively. The median OS of 11 patients received whole brain radiotherapy(WBRT)combined with chemotherapy was 48 months. The median OS of 7 patients treated with stereotactic radiosurgery(SRS) combined with chemotherapy had no significant difference when compared to the former (P=0.233). Survive analysis showed that age was prognostic factor for PCNSL patients(P=0.030).</p><p><b>CONCLUSION</b>Diffuse large B cell lymphoma was the main type of PCNSL, single or multiple location, presented with increased intracranial hypertension or focal neurological deficits. Age was the key prognostic factor for patients. Surgery was suitable for patients with supertentorial and superficial tumor or with acute intracranial hypertension syndrome. SRS was a feasible local therapy which alleviated the symptoms and led to less toxicity. PCNSL patients might benefit from multimode therapy.</p>

Clinical decision on a patient with esthesioneuroblastoma / 中国肿瘤临床

Olfactory neuroblastoma is a rare malignant tumor. Although multiple therapeutic modalities including surgery, radio-therapy, or chemotherapy could be used in patients with olfactory neuroblastoma, no standardized treatment has been achieved. This re-view introduces a case of adult olfactory neuroblastoma treated by a multiple disciplinary team in Tianjin Medical University Cancer In-stitute and Hospital. This review also aims to explore a complete set of diagnostic and treatment practices for the benefit of future pa-tients.
