The results of a recent Phase 2 trial indicate that Velcade-doxorubicin-dexamethasone treatment can reverse multiple myeloma-associated kidney damage in myeloma patients suffering from kidney failure. The regimen also improved patients’ disease statuses and was associated with few severe side effects.

Multiple myeloma affects plasma cells, a subset of white blood cells that fight infections by producing antibody. In multiple myeloma patients, cancerous plasma cells produce one kind of abnormal antibody.

In some myeloma patients, this abnormal antibody binds to a protein produced in the kidney.  These antibody-protein complexes then accumulate in the …

During the course of their disease, multiple myeloma patients may develop a condition called amyloidosis.  Amyloidosis is a disease in which proteins accumulate in organs such as the heart or kidneys, leading to organ damage and complications associated with some multiple myeloma treatments.

The following article describes amyloidosis as it relates to multiple myeloma and includes some of the current treatment recommendations for patients with this dual diagnosis.

What Is Amyloidosis?

Amyloidosis occurs when proteins accumulate in organs such as the heart, kidney, liver, or intestines.

There are …

The results of a recent study suggest that although the chromosomal abnormalities t(4;14) and del(17p) are associated with poor prognoses in newly diagnosed multiple myeloma patients, Velcade-dexamethasone therapy improved survival among patients with t(4;14) compared to treatment with vincristine, doxorubicin, and dexamethasone.

However, patients with the t(4;14) abnormality did not respond as well to Velcade and dexamethasone as patients without the abnormality.  Patients with del(17p) did not show the same improvements when treated with Velcade-dexamethasone.

The presence of chromosomal abnormalities in the plasma cells of multiple myeloma patients is associated with poor …

The use of thalidomide (Thalomid) in induction and maintenance therapies for multiple myeloma patients receiving a stem cell transplant resulted in better overall response rates but did not significantly improve overall survival, according to a Phase 3 study recently published in the journal Blood.

In their study, researchers randomly assigned 556 patients to receive three cycles of either vincristine (Oncovin), doxorubicin, and dexamethasone [VAD] or thalidomide, doxorubicin (Adriamycin), and dexamethasone (Decadron) [TAD] as induction therapy. All patients received high-dose melphalan (Alkeran) with an autologous stem cell transplant, …

A recent study published in the Journal of Clinical Oncology determined that patients who achieved very good partial response (VGPR) or better after high-dose chemotherapy and stem cell transplantation experienced significantly longer event-free and overall survival.

“Very good partial response” is one of the terms defined by the International Myeloma Working Group (IMWG) to categorize how patients respond to treatment. According to IMWG criteria (see related Beacon news), patients reach very good partial response when the level of abnormal “M” proteins in their blood decreases by 90 percent.

Previous studies evaluating …

Curcumin has been garnering increased attention as a potential anticancer treatment. It is the major active compound in turmeric, a popular Indian spice made from the rhizomes, or underground stalks, of a plant in the ginger family.

In multiple myeloma and the precursor condition monoclonal gammopathy of undetermined significance (MGUS), cell culture studies and one animal study have shown that curcumin can kill cancer cells and prevent them from multiplying. The Beacon also found two early-stage clinical trials studying curcumin’s effects in people with multiple myeloma and …

The results of a recent Phase 3 clinical trial indicate that treatment with high-dose melphalan (Alkeran) prior to a stem cell transplant results in a longer period of remission for myeloma patients than treatment with reduced-intensity melphalan. The differences in remission duration were larger for patients younger than 60 years old.

Based on the significant difference in progression-free survival between the two treatment groups, the researchers concluded that high-dose (200 mg/m²) melphalan is more effective in preparing younger, medically fit multiple myeloma patients for stem cell transplants. However, reduced-intensity (100 mg/m²) …
