Objective To evaluate the toxicity and efficacy of thermotherapy used with a streptococcus A preparation (OK-432) and cisplatin for treating malignant pleural effusion (MPE),and to assess patients' tolerance.Methods A total of 158 MPE patients were randomized into experimental and control groups.Closed drainage of the thoracic cavity was conducted with all the patients using a central venous catheter,and systematic chemotherapy was administered individually on the basis of each patient's condition.Patients in the control group were treated with intrapleural administration of OK-432 (0.5 mg) and cisplatin (40-60 mg) weekly for a maximum of 4 weeks,while those in the experimental group were given 60min of high frequency electrical thermotherapy 30-60 min after the administration of the drugs.The thermotherapy was at 40-43.5 ℃ and administered twice a week.Efficacy,quality of life and toxicity were compared between the two groups.Results The overall response rate in the experimental and control groups was 90.6% and 79.5% respectively;and grade I-II toxicity was similar.No grade Ⅲ or more serious toxicity was observed.The life quality scores in both groups were significantly improved after treatment.Conclusions Thermotherapy combined with intrapleural OK-432 and cisplatin can improve the effectiveness of therapy and life quality in MPE patients without increased toxicity.

Objective To study the clinical characteristics and treatment of primary nasal B-cell lymphoma (PNBCL). Methods A retrospective analysis was performed based on the clinical records of 18 PNBCL cases who were treated from January 2009 to June 2015. The clinical manifestations, imaging features, diagnosis approaches and treatment of them were analyzed. Results The main symptoms were nasal obstruction and rhinorrhea. Of all patients, 15 cases were in Ann Arbor stageⅠE-ⅡE, and 3 cases were in Ann Arbor stageⅢE-Ⅳ. The median age was 51 years (12-76 years). The ratio of men to women was 11:7. Only 1 patient had B symptoms. Elevated LDH levels were observed in 4 patients. 13 patients were diffuse large B-cell lymphoma(DLBCL), 3 patients were mantle cell lymphoma, and 2 patients were Burkitt lymphoma. CT examination showed the abnormal nasal soft tissue shadow, with unilateral location and light to moderate enhancement. 14 patients received combination chemotherapy only, and 3 patients received chemotherapy and radiotherapy. Total effective rate was 82.3 % (14/17). At the time of last follow-up, 5 patients died, and the 3-year OS rate was 54.5%(6/11). Conclusions Most PNBCL patients are in Ann Arbor stageⅠE-ⅡE and B symptoms are rare, and the most common pathological types is DLBCL. The treatment for PNBCL is chemotherapy, radiotherapy can assist, but the prognosis is poor, and innovative chemotherapy regimens are necessary.

Primary hepatic lymphoma (PHL) is an extremely rare disease without any unified diagnostic criterion.The symptoms are usually nonspecific.Liver biopsy remains the most valuable tool for diagnosis of PHL.The predominant histology of PHL is diffuse large B-cell lymphoma.The therapeutic modalities are variable,including surgery,chemotherapy,radiotherapy,or combination of the various processes.This article described a 33-year-old man with diffuse large B-cell PHL who was treated at the Affiliated Cancer Hospital of Shanxi Medical Univeitity Blood Disease Diagnosis and Treatment Center in February 2014.The patient benefited from eight-cycle chemotherapy.At present,the patient is disease-free and undergoes regular follow-up.

Objective To research correlation of serum protein spectrometry and lymphoma markers for diffuse large B cell lymphoma (DLBCL) patients. Whether there is relative between the protein and prognosis will be further researched. Methods Serum protein spectrometry of 62 DLBCL patients was detected by the SELDI-TOF-MS technique and Weak cation exchange 2 (WCX2) chip. Lactate dehydrogenase (LDH) was detected by biochemistry method. Beta-2-microglobulin (β2-MG) and cancer antigen125(CA125)were detected by enzyme-linked immunosorbent assay (ELISA). The level of LDH, β2-MG and CA125 for DLBCL patients between 11×103～12×103 protein expressed positively and negatively was analyzed. Meanwhile,correlation analysis and survival analysis were done. Results LDH, β2-MG and CA125 in 11×103～12×103protein expressed positive group were (523.30±435.96)U/L, (3.23±1.24)mg/L, (81.07±61.39)U/L respectively,and they were higher than that in negative group (P＜0.05). 11×103～12×103 protein was positive correlated to LDH, β2-MG and CA125 (P＜0.01). The survival time in 11×103～12×103 protein expressed in positive group,in which median survival time was 11 months, was shorter than that in negative group(P ＜0.01). The survival time in LDH normal group was longer than that in increased group(P ＜0.01). The survival time of β2-MG and CA125 had no significant difference between increased group and normal group. Conclusion LDH and 11×103～12×103 protein are expected to be prognosis indicators for DLBCL patients.
