Efficacy of Standard Dose R-CHOP Alternating With R-HDAC Followed by Autologous Hematopoietic Cell Transplantation as Initial Therapy of Mantle Cell Lymphoma, a Single-Institution Experience.

Background: Young fit patients with mantle cell lymphoma (MCL) are commonly treated with induction chemotherapy followed by high-dose chemotherapy and autologous hematopoietic cell transplantation (AHCT). Induction regimens with modifications of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) and/or incorporation of high-dose cytarabine (HDAC) appear more effective than R-CHOP alone.

Patients And Methods: We adopted a modification of the Nordic protocol using standard, rather than higher dose R-CHOP, alternating with HDAC (rituximab plus HDAC), for 3 cycles each or, for patients already treated with R-CHOP alone before referral for AHCT, an additional 2 cycles of rituximab plus HDAC.

Neuropathy and efficacy of once weekly subcutaneous bortezomib in multiple myeloma and light chain (AL) amyloidosis.

Introduction: Randomized studies have shown that bortezomib (BTZ) can be given weekly via intravenous (IV) route or twice weekly via subcutaneous (SC) route with lower neuropathy risk and no loss of anti-myeloma efficacy compared to original standard IV twice weekly schedule. Weekly SC should therefore yield the best therapeutic index and is widely used but has not been compared to established administration schedules in the context of a clinical trial.

Methods: Comprehensive electronic medical record review was done for disease control and neuropathy symptoms of 344 consecutive patients who received their first BTZ-containing regimen for myeloma or AL amyloidosis before or after we changed to SC weekly in December 2010.
