A 35-year-old Japanese woman with this type of lymphoma relapsed after ABVD chemotherapy received salvage chemotherapies. Even after hidh-dose chemotherapy followed by autologous stem cell transplantation, only partial response could be achieved. Consolidative involved-field radiation therapy did not induce complete response and four months later a new lesion appeared at the skin inside the irradiated field. Based on the strong expression of CD30, brentuximab vedotin was administered and complete response was attained. Although brentuximab vedotin was discontinued after 9 cycles due to peripheral neuropathy, the response has been maintained for three years without subsequent allogeneic transplantation. There has been no report that patient with the lymphoma who were successfully managed only with brentuximab vedotin after progression following autologous SCT. Our case suggested not only that it might be a potential therapeutic agent for bridging therapy before allogenic transplantation, but also that it could confer long-term remissio...

Melphalan, prednisone and bortezomib (MPV) is a current standard in the treatment of transplant ineligible newly diagnosed multiple myeloma (TI NDMM) and has been used as a control arm in several recent phase 3 clinical trials. Bortezomib related peripheral neuropathy (PN) is a limiting factor to apply the original MPV dose and schedule and reduced intensity schedules have been used both in clinical practice and in clinical trials. However, the feasibility of full-dose MPV and the impact on efficacy of dose intensity in real world have not been described.
The use of bortezomib in treatment of multiple myeloma (MM) has become a backbone of many induction regimens. Its efficacy when given twice weekly is often at the expense of peripheral neuropathy (PN) despite of adopting subcutaneous (SQ) administration. In an attempt to reduce the impact on quality of life (QOL) without compromising response, studies using weekly bortezomib with cyclophosphamide and dexamethasone (VCD) or lenalidomide and dexamethasone (RVD-lite) in transplant ineligible patients have demonstrated to be effective treatment regimens.
In the present study, the effect and toxicity of 1.6mg/m2 and 1.3mg/m2 bortezomib BCD on multiple myeloma (MM) were analyzed retrospectively. From January 2016 to December 2018, 82 newly diagnosed MM patients received minimal 4 cycles of either 1.6mg/m2 (bortezomib 1.6mg/m2, d1, d8, d15, d22; cyclophosphamide 300 mg/m2 d1, d8, d15; dexamethasone 20 mg d1, d2, d8, d9, d15, d16, d22, d23; 35 days per cycle) or 1.3mg/m2 (bortezomib 1.3mg/m2, d1, d4, d8, d11; cyclophosphamide 300 mg/m2 d1, d8, d15; dexamethasone 20 mg d1, d2, d4, d5, d8, d9, d11, d12; 21 days per cycle) bortezomib BCD regimen.
Bortezomib is a proteasome inhibitor commonly used for the treatment of multiple myeloma (MM). Its proven efficacy has resulted in increased survival rates in both the newly diagnosed and relapsed/refractory cohorts. Bortezomib-induced peripheral neuropathy (BIPN) is a disabling and common toxicity associated with this treatment, typically requiring dose reduction, delay or cessation of treatment protocol. It typically presents as numbness, tingling and paraesthesia manifesting in the peripheral domain in a glove and stocking distribution.
Monoclonal gammopathy of undetermined significance (MGUS) is the precursor condition of multiple myeloma (MM) and related disorders. MGUS is relatively common and although it is often referred to as asymptomatic, individuals with MGUS have been reported to develop peripheral neuropathy (PN). However, the literature is unclear on the prevalence, implications, and even the existence of MGUS associated PN. Therefore, we were motivated to assess the prevalence and risk of PN in a large population of individuals with MGUS.
In this study we sought to identify mechanisms of disease development by comparing the immune tumor microenvironment (iTME) of patients with POEMS syndrome to that of patients with MGUS.
