To explore the risk factors, prognosis and curative effect of elderly patients with MM renal damage.

118 patients with primary elderly MM treated in our hospital from January 2011 to December 2018, were enrolled analyzed retrospectively. The clinical characteristics and prognosis of renal function impairment group (RI group) and normal renal function group (non-RI group) were compared. The difference of renal efficacy and survival benefit between the patients treated with bortezomib, thalidomide (combination group) and chemotherapy regimen containing only one of them (single drug group) in RI group was compared.

Univariate analysis showed that DS stage, pulmonary infection, uric acid, β

microglobulin and leukocyte in RI group were higher than those in non-RI group, but hemoglobin was lower than that in non-RI group (P<0.05). Multivariate logistic regression analysis showed that β

microglobulin was the independent risk factor for renal damage in elderly patients with MM. Kaplan-Meier method showed that the OS and PFS in RI group were significantly lower than those in non-RI group (P<0.05). The renal efficacy in the combined treatment group was significantly better than that of the single drug group (P<0.05), and it could bring benefit to the PFS of the elderly patients with MM renal damage (P<0.05).

The prognosis of elderly MM patients with impaired renal function is poor. The prognosis of these patients can be improved by selecting chemotherapy regimen containing bortezomib and thalidomide at the same time, and monitoring, controlling all kinds of risk factors actively.

To investigate the short-term efficacy and safety of generic bortezomib in the treatment of Chinese patients with multiple myeloma (MM).

Clinical data of 62 MM patients (median age of 62 years) who had accepted at least 2 cycles of chemotherapy based on generic bortezomib in our center from December 2017 to July 2019 were retrospectively analyzed, including 47 newly diagnosed patients and 15 with disease recurrence or progression.

Anemia, renal dysfunction, hypoproteinemia and high level of β

-microglobulin were all improved rapidly after induction treatment. In 56 patients who had completed at least 4 cycles of chemotherapy, the overall response rate (ORR) was 85.7%, and 64.3% of the patients achieved very good partial response (VGPR) or better, and 28.6% achieved complete remission (CR) or better. In the 19 patients who had already completed all planned induction and consolidation treatment (9 cycles of chemotherapy or 4-6 cycles of chemotherapy plus autologous hematopoietic stem cell transplantatioble toxicity profile. However, the long-term outcomes will be examined through further follow-up.

To investigate the efficacy, survival and adverse effects of non-transplanted multiple myeloma (MM) patients treated with bortezomib maintenance.

A total of 25 newly diagnosed/relapsed non-transplanted MM patients treated in West District of Beijing Chaoyang Hospital from June 2004 to November 2015 were analyzed retrospectively. All patients received PD regimen (bortezomib and dexamethasone), including bortezomib at a dose of 1.3 mg/m

and dexamethasone 20 mg on days 1, 8, 15, 22 in a 3-month cycle.

Till November 1, 2017, 5 patients achieved stringent complete response (sCR), 8 patients achieved complete response (CR), 7 patients achieved very good partial response (VGPR), 4 patients achieved partial reponse (PR), while 1 patient achieved stable disease (SD). After maintenance therapy, 21 patients maintained the efficacy above PR, of which 1 patient was improved from CR to sCR; 4 patients adjusted chemotherapy after disease progressed. Median maintenance therapy was 9 cycles (range from 6 to 31), and the median maintenance time was 27 months (range from 18 to 97). Median follow-up time was 73 months (range from 25 to 171). Median progress-free survival (PFS) time was 30 months (range from 9 to 105) and overall survival (OS) time was 57 months (range from 27 to 160). Till November 1, 2019, 3-year survival rate was 84% (21/25), and 5-year survival rate was 72% (13/18). The most common adverse events were transient leukopenia, thrombocytopenia and peripheral neuropathy, which the patients could tolerate after the prevention and treatment.

Bortezomib-based maintenance therapy for non-transplanted MM patients can be an option in consideration of its safety and efficacy.

To investigate the effect of neutrophil/lymphocyte ratio (NLR) and monocyte/lymphocyte ratio (MLR) in the valuation prognosis of patients with multiple myeloma (MM).

The clinical data of 82 patients with initially diagnosed MM admitted to Gansu Provincial People’s Hospital was analyzed retrospectively. NLR and MLR were calculated based on blood routine results respectively. selleck compound The optimal cut-off point of NLR and MLR was determined according to the ROC curve, and the patients were divided into the high NLR/MLR group and the low NLR/MLR group. The general data, biochemical indicators and prognosis of the patients in each groups were compared respectively. The prognostic significance of the high NLR/MLR group and the low NLR/MLR group in patients between different treatment regimens and different clinical characteristics were analyzed. Risk stratification was designed based on NLR and high MLR as two risk factors, and the effect of risk factors, on the prognosis of MM patients were compared.

ROC curve analyswith 2 risk factors showed a poorer prognosis than those with 0-1 risk factor.

Elevated NLR and MLR are associated with poor prognosis in MM patients and may serve as the cost-effective and readily available prognostic biomarkers.
