Objective To review the efficacy of bisphosphonates in reducing skeletal events in patients with multiple myeloma. Methods Two hundred and five patients with newly diagnosed MM were enrolled in this retrospective study,with bisphosphonates or not.Skeletal-related events,therapeutic reaction of myeloma bone disease and patient survival were analyzed. Results The occurrence of skeletal-related events (SRE) per patient year (P<0.01) and the time to first SRE (P<0.05)were significantly lower in the reatment group than in the untreated group. After 6 cycles of treatment, a significant higher percentage of effective and marked effect patients were observed through X ray in the treatment group (80.0 %) compared to the untreated group (48.7 %), P<0.001. There was no overall significant difference in the level of serum calcium between the two groups (P=0.278). After 6 cycles of treatment, the patients who received bisphosphonates had significant decreases in bone pain and lower ECOG score (ECOG≤2) compared to the untreated group (P<0.05). Bisphosphonates were tolerated well, and the common adverse reaction including gastrointestinal reaction (3 cases,3.3 %),fever (lcase,1.1%) and skin rash (2 cases,2.2 %).There was no significant difference in overall survival between the two treatment groups,(P=0.580).Conclusion Infusions of Bisphosphonates could reduce the occurrence of skeletal- related events (SRE), prolong the time to first SRE and improve the quality of life of patients with multiple myeloma. Bisphosphonates could not prolong survival time of myeloma patients.

Objective To analyze the clinical characteristics,therapeutic outcome and prognostic factors of mantle cell lymphoma(MCL)in China.Methods Clinical records of 27 MCL patients were retrospectively analyzed.The results of rituximab combined therapy and conventional therapy regimens were compared,and prognostic factors were analyzed.Results The median age of the 27 patients was 59,with marked male predominance(2.4∶1).There were 88.9% patients with bone marrow involvement at clinical stage Ⅲ~Ⅳ,59.3% with spleen involvement,44.4% with LDH elevated,33.3% with B symptoms and 11.1% with liver involvement.Among the 21 patient with conventional cytogenetic results,7 patients had additional chromosome aberration and 4 patients had more than 4 chromosomes aberration.15/20 patients were misdiagnosed in local hospitals,most of which were diagnosed as CLL/SLL.In 24 untreated patients,the CR/CRu,3 years' OS and PFS in rituximab combined therapy(RCT group)were all significantly higher than those in CT group(87.5% vs 31.3%,87.5% vs 24.1%,70.0% vs 26.9%,P

Objective To identify the clinical and pathological features of blastic plasmacytoid dendritic cell neoplasm (BPDC). Methods The characteristics of BPDC hematodermic neoplasm were discussed with a report of two new cases and review the literatures. Results Both patients presented with skin nodules and the tumors were CD+4 and CD+56. Lineage specific markers for B- and T-cell were negative and the tumors did not express myeloperoxidase. Systemic chemotherapy resulted in complete remission, but the disease relapsed quickly and were unresponsive to further chemotherapy. The patients died 26 months and 11 months respectively after diagnosis. Conclasion BPDC hematodermic neoplasm is a rare subtype of lymphoma with distinct clinicopathologic and immunophenotypic features. The disease often has a fulminant course with a poor prognosis. More recent studies suggest that there is a derivation from a plasmacytoid dendritic cell precursor.

Objective To identify the clinical and pathological features of aggressive natural killercell leukemia (ANKL). Methods 9 cases of ANKL fulfilling the criteria defined by the World Health Organization classification were retrospectively analyzed with literature review, Results Systemic symptoms, hepatomegaly, splenomegaly, lymphadenopathy were frequently observed. Liver dysfunction, neutropenia, anemia and thrombocytopenia were often seen during the course of the disease. Most of the bone marrow shows focal or subtle infiltration by the neoplastic cells. The immunophenotype of cells was characteristic for CD+56, sCD-36, and variable expression of CD2, CD7, CD8 and CD11b. T-cell receptor (TCR) genes rearrangement were in germline configuration. Median survival time was 9 weeks. Conclusion ANKL is an entity of mature cytotoxic NK-cell neoplasms with distinct phenotype and disease presentations. The disease often has a fulminant course with a poor response to chemotherapy and a short survival time. Patients achieving CR showed significantly longer survival time, but the remission did not translate into cure of the disease.

Objective To improve the recognition of precursor T- lymphoblastic lymphoma (T-LBL)of the breast. Methods One case of breast T- LBL was reported, the development of breast non-Hodgkin lymphoma and T-LBL presenting as breast masses was reviewed. Results One case of breast T-LBL was diagnosed, the patient with a high leukocyte count, breast mass and peripheral lymph nodes was treated with Hyper-CVAD regimen after active therapy and achieved complete remission (CR). Followed by maintenance therapy with Hyper-CVAD regimen for three times, disease free survival had been obtained five month.Conclusion Lymphoma of the brest is a rare malignancy. T-LBL is a highly aggressive disease with adverse prognosis, it is very uncommon for presenting as lymphoma of breast. Initiation of intensive muhiagent chemotherapy can improve the free survival and the prognosis.

Objective To report two cases of severe pulmonary complication after bortezomib treatment for multiple myeloma. Methods Two cases of severe pulmonary complication after bortezomib treatment patients with relapsed multiple myeloma wereas discussed with review of literature. Results Two relapsed MM patients were treated with bortezomib and thalidomide or dexametbasone. Cough, dyspnea, fever and hypoxia developed after completion of bortezomib. Chest X-ray revealed bilateral pulmonary infiltrates,but infection was not identified with sputum cultures, and broad-spectrum antibiotics were ineffective.Conclusion Severe pulmonary injury was rare complication in patients receiving treatment for multiple myeloma, however, it was a life-threatening disorder. Prophylaxis corticosteroids maybe effective. Although corticosteroids are effective, but the mechanism of lung injury associated with bortezomib is unclear, and further evaluation of this potential toxicity is appropriate.
