Purpose: Prevention of chemotherapy-induced nausea and vomiting (CINV) is particularly challenging for patients receiving highly emetogenic preparative regimens before autologous stem cell transplantation (ASCT) due to the daily and continuous emetogenic stimulus of the multiple day chemotherapy. While studies have shown effective prevention of CINV during the conditioning phase with NK 1 receptor antagonist (NK 1 RA)-containing regimens, there have been no studies evaluating antiemetic use during chemomobilization prior to ASCT., Methods: This multicenter, open-label, phase IIa study evaluated the efficacy of every-other-day dosing of NEPA administered during chemomobilization in patients with relapsed-refractory aggressive non-Hodgkin's lymphoma. Eighty-one patients participated., Results: Response rates were 77.8% for complete response (no emesis and no rescue use), 72.8% for complete control (complete response and no more than mild nausea), 86.4% for no emesis, and 82.7% for no rescue use during the overall phase (duration of chemomobilization through 48 h after). NEPA was well tolerated with no treatment-related adverse events reported., Conclusion: NEPA, administered with a simplified every-other-day schedule, show to be very effective in preventing CINV in patients at high risk of CINV undergoing to chemomobilization of hematopoietic stem cells prior to ASCT., (© 2021.

Introduction: High-dose melphalan (HDMel) is the most common conditioning chemotherapy regimen for autologous stem cell transplantation (SCT) in patients affected by multiple myeloma (MM). No consensus exists for the emetogenicity or prophylaxis of chemotherapy-induced nausea and vomiting (CINV) in this regimen., Methods: Data on the incidence and efficacy/safety of CINV prophylaxis among patients affected by MM undergoing autologous SCT with the HDMel regimen was extracted from electronic databases and analyzed., Results: Eleven studies involving multiple CINV prophylaxis regimens were identified and included. No consensus on HDMel emetogenicity was reached, but most studies summarized the emetogenicity as moderate-high risk. An aprepitant-based three-drug regimen (aprepitant + serotonin receptor antagonist (5HT3RA) + dexamethasone) showed better efficacy than a two-drug regimen (5HT3RA + dexamethasone) for CINV prevention without increasing the frequency in adverse events., Conclusions: The aprepitant-based three-drug regimen should be the regimen of choice for CINV prophylaxis for MM patients undergoing autologous SCT with HDMel conditioning.

Purpose: Bortezomib, a proteasome inhibitor drug very effective against multiple myeloma, may induce the so-called bortezomib-induced peripheral neuropathy (BIPN), hardly manageable with common analgesic drugs. This study assessed the effectiveness of controlled-release (CR) oral oxycodone in controlling pain and its interference on daily functions of patients with hematologic malignancies affected by BIPN., Methods: Forty-six patients (median age, 62 years) affected by myeloma and lymphoma, complaining of BIPN-related pain of moderate-to-severe intensity and unresponsive to previous analgesic treatments, were treated with CR oxycodone. The intensity of continuous and brief pain (BP) along with interference of pain with the common daily dimensions of feeling and function were evaluated by using an 11-point numerical rating scale (NRS); a global patient evaluation of efficacy was also performed., Results: The daily average dose of CR oxycodone administered was 28.46 mg (range, 20-80 mg). The pain intensity decreased from a mean NRS value of 7.6 at baseline to 1.3 on day 14. The frequency of BP was reduced from 61 to 47% of patients and its intensity from 7.4 to 3.1 NRS score. A similar trend to decreasing values was observed for all the daily life functions. Slight- or mild-intensity side effects were observed in 23 patients (51%). At the end of the study, 75% of patients found the treatment effective or very effective., Conclusion: CR oxycodone for relief of BIPN-related pain was effective and well tolerated. The pain control significantly improved also the quality of the daily life functions, which are usually compromised in these suffering patients.
