Elevated NLR was associated with poor OS in MM patients receiving induction therapy with bortezomib-based regimens, but it was not an independent prognostic factor in this patient cohort.

BACKGROUND: The Controlling Nutritional Status (CONUT) score, a novel immuno-nutritional index, was reported as a predictor of overall survival (OS) in some tumors. OBJECTIVE: We aimed to investigate the association between baseline CONUT Score and clinical outcomes in patients with multiple myeloma (MM) METHODS: We performed a retrospective analysis of 245 patients with MM. The CONUT score was determined prior to therapy. RESULTS: Among the entire cohort, the complete remission rate was markedly higher in the low-CONUT (⩽ 3) group compared to the mid-CONUT (4–9) group or high-CONUT (> 9) group (44.1% vs 25.8%, P= 0.039; 44.1% vs 12.5%, P= 0.002). Patients with CONUT score > 9 had significant poor prognosis, and CONUT score ⩽ 3 group showed better survival outcome than other groups in OS (P< 0.001). Besides, we stratified the patients by combining International Staging System (ISS) stage and CONUT score in a model, and found that CONUT score could improve the prognostic impact of ISS stages on OS In multivariate analysis, older age (⩾ 70 years) and a high CONUT score (⩾ 4) were independent prognostic risk factors for OS. CONCLUSIONS: The CONUT score was a predictor of OS in MM patients especially in cases with both low ISS staging and CONUT score. The baseline CONUT score may be an early and practical indicator of the efficacy of anti-myeloma treatment.

Bortezomib has proven to be active in patients with multiple myeloma (MM), including elderly patients. The aim of this study was to evaluate the efficacy and toxicity of bortezomib in combination with intermediate‐dose dexamethasone (Dex) and thalidomide in untreated MM patients aged ≥65 years in a Chinese single center. In this study, 18 patients were treated with bortezomib at 1.3 mg/m2 IV on Days 1, 4, 8, and 11 and Dex at 20 mg/day IV on Days 1–4 and 8–11 simultaneously. Thalidomide at dose of 100 mg/day was given everyday. The mean number of cycles of bortezomib treatment was 2.06. Three patients (17%) achieved a complete response (CR), four (22%) a very good partial response (VGPR), and nine (50%) a PR, resulting in an overall response rate of 89%. The median time to response was 22 days (range 14–50 days). The duration of response was significantly longer in patients achieving a CR/VGPR with respect to those achieving only a PR (8.5 vs. 4.2 months, P = 0.03). Grade 3–4 toxicities occurring in patients comprised weakness, thrombocytopenia, diarrhea, infection, and neuropathy. Only one patient suffered from deep vein thrombosis. This preliminary experience in Chinese patients indicated that bortezomib‐Dex‐thalidomide is highly effective in elderly untreated patients with MM, even in patients with poor prognostic features.

Studies have shown that the bortezomib-based retreatment of patients with multiple myeloma (MM) may prolong control of the disease. The optimal duration of bortezomib-based retreatment in relapsed or refractory MM is unknown. The present retrospective study evaluated the efficacy and safety of short-course bortezomib-based retreatment in patients who had received bortezomib-thalidomide-dexamethasone (VTD) treatment for the initial therapy of newly diagnosed MM. The clinical records of 20 patients who had received short-course bortezomib-based retreatment in a single center were reviewed. Patients received a median of two cycles of bortezomib as the retreatment and the overall response rate was 90%. Six (30%), eight (40%) and four (20%) patients achieved a complete response (CR), a very good partial response and a partial response, respectively. Of the 10 patients who had achieved a CR during the initial VTD treatment, six experienced a repeat CR during the retreatment. The median duration of the response was nine months and the median time to progression was 10.5 months. The most common grade I and II adverse events were thrombocytopenia and neutropenia. The short-course bortezomib-based retreatment was well tolerated and the favorable response rates observed suggest that it may be an effective and convenient treatment option for certain patients, particularly elderly patients.

Real-world costs during treatment of RRMM varied greatly. Total costs during bortezomib-based regimens are significantly higher compared with non-bortezomib regimens. Further multi-center studies are needed to assess the cost-effectiveness of bortezomib for the treatment of RRMM in China.

<b><i>Introduction:</i></b> Recently, treatment with proteasome inhibitors and immunomodulators has improved the prognosis of multiple myeloma (MM). However, in a complex real-world situation, the patient’s ability to undergo regular and timely treatment as prescribed in clinical trials has not been studied, as well as the impact of extended treatment intervals due to different reasons. This study aimed to evaluate the treatment interval and clinical characteristics of 122 patients with primary myeloma in our hospital and explore the prognostic effects of different treatment intervals. <b><i>Methods:</i></b> In total, 122 patients with MM were analyzed retrospectively in our hospital from January 2007 to June 2018. The clinical and laboratory data (such as age, International Staging System [ISS] stage, chromosome, etc.) and subsequent treatment intervals were analyzed. The Cox proportional hazard regression model was used for univariate and multivariate analyses of overall survival (OS) and progression-free survival. The Kaplan-Meier method was used in survival analysis, and the log-rank test was used to test survival difference. <i>p</i> &#x3c; 0.05 was considered to indicate statistical significance. <b><i>Results:</i></b> We found that prolonging the interval treatments (&#x3e;28 days) shortened the OS in the younger and high-risk subgroups. On the contrary, the OS of the older and low-risk subgroups was not shortened. OS was also shortened in patients who were suitable for transplantation but did not receive a transplant. Univariate and multivariate analyses showed that extension of treatment interval was a risk factor for OS shortening. In addition, prolonged treatment interval was due to iatrogenic and family reasons. <b><i>Conclusion:</i></b> Extended treatment interval is unfavorable in young and high-risk MM patients and those suitable for transplantation but who did not receive a transplant. However, it has a faint impact on the elderly and low-risk subgroups.
