Active clinical trials for "Neoplasms, Plasma Cell"

Multiple myeloma (MM) is a malignancy of plasma cells engaging in monoclonal immunoglobulin production. A strong presumption was established between exposure to pesticides and the risk of MM. The French West Indies departments of Guadeloupe and Martinique are characterized by a wide use of pesticides related to bananas plantation, particularly chlordecone which has been classified by IARC as possibly carcinogenic and has recognized hormonal properties (endocrine disruptor). The objective of this study is to measure the association between exposure to pesticide and other environmental factors in the occurrence of MM in Guadeloupe and Martinique and to estimate the proportion of cases of MM attributable to pesticide exposure. Genetic susceptibility markers and their links to environmental factors will be subsequently studies from blood samples collection.

Hypothesis: the hyponatremia of multiple myeloma (m.m.)is true and not pseudohyponatremia by using the stewart approach to acid - base interpretation, would like to show that the positive charged m- proteins produced in m.m.result in true hyponatremia.

This is a multi-center, prospective, non-interventional study. Eligible newly diagnosed elderly multiple myeloma (MM) patients will receive comprehensive geriatric assessment (cGA) including ECOG scale, questionaires of ADL（activities of daily living), IADL(instrumental ADL),MNA-SF(mini-nutritional assessment), GDS(geriatric depression scale), MMSE(mini-mental state examination), SF-36 and CCI (charlson comorbidity index). Patients will get standard care for MM and receive the above assessments at baseline and after cycle 1, 4 and 12 for treating MM.Follow-up information and survival data of these MM patients would be collected. We would evaluate the cGA status of these newly diagnosed elderly MM patients and investigate the association of cGA parameters with patient's survival.

The main purpose of this study is to examine differences in quality of life and psychological distress for both Multiple Myeloma patients receiving treatment and their caregivers and to assess patient and caregiver prognostic understanding (understanding of the likely course of a disease over time) of Multiple Myeloma to guide development of more personalized treatment plans. This study looks to further understand quality of life changes throughout multiple myeloma therapy for both patients and caregivers to help determine ways to improve patient and caregiver understanding of illness and in turn, tailor customized treatment that best aligns with patient preferences. The study will use a series of questionnaires to measure quality of life, mood, coping strategies, and prognostic understanding.

Collection of retrospective additional data (survival, biological, disease response data) following the study IFM 2013-04.

The purpose of this study is to determine whether the orthostatic hypotension reported among subjects during bortezomib-containing regimen is caused by a dysfunction of the autonomic nervous system (ANS).
