A well-matched donor (related or unrelated) remains the preferred donor for patients undergoing allogeneic HCT; however, a large number of patients rely on alternative donor choices of mismatched related (haploidentical) or unrelated donors to access HCT. In this retrospective study, we investigated outcomes of patients who underwent mismatched donor (related or unrelated) HCT with a radiation-based myeloablative conditioning MAC regimen in combination with fludarabine, and post-transplantation cyclophosphamide (PTCy) as higher-intensity graft-versus-host disease (GVHD) prophylaxis. We retrospectively assessed HCT outcomes in 155 patients who underwent mismatched donor HCT (related/haploidentical versus unrelated [MMUD]) with fractionated-total body irradiation (fTBI) plus fludarabine and PTCy as GVHD prophylaxis at City of Hope from 2015 to 2021. Diagnoses included acute lymphoblastic leukemia (46.5%), acute myelogenous leukemia (36.1%), and myelodysplastic syndrome (6.5%). The median age at HCT was 38 years, and 126 patients (81.3%) were an ethnic minority. The Hematopoietic Stem Cell Transplantation Comorbidity Index was ≥3 in 36.1% of the patients, and 29% had a Disease Risk Index (DRI) of high/very high. The donor type was haploidentical in 67.1% of cases and MMUD in 32.9%. At 2 years post-HCT, disease-free survival (DFS) was 75.4% and overall survival (OS) was 80.6% for all subjects. Donor type did not impact OS (hazard ratio [HR], .72; 95% confidence interval [CI], .35 to 1.49; &lt;em&gt;P&lt;/em&gt; = .37) and DFS (HR, .78; 95% CI, .41 to 1.48; &lt;em&gt;P&lt;/em&gt; = .44), but younger donors was associated with less grade III-IV acute GVHD (HR, 6.60; 95% CI, 1.80 to 24.19; &lt;em&gt;P&lt;/em&gt; = .004) and less moderate or severe chronic GVHD (HR, 3.53; 95% CI, 1.70 to 7.34; &lt;em&gt;P&lt;/em&gt; &lt; .001), with a trend toward better survival (&lt;em&gt;P&lt;/em&gt; = .099). The use of an MMUD was associated with significantly faster neutrophil recovery (median, 15 days versus 16 days; &lt;em&gt;P&lt;/em&gt; = .014) and platelet recovery (median, 18 days versus 24 days; &lt;em&gt;P&lt;/em&gt; = .029); however, there was no difference in GVHD outcomes between the haploidentical donor and MMUD groups. Nonrelapse mortality (HR, .86; 95% CI, .34 to 2.20; &lt;em&gt;P&lt;/em&gt; = .76) and relapse risk (HR, .78; 95% CI, .33 to 1.85; &lt;em&gt;P&lt;/em&gt; = .57) were comparable in the 2 groups.

BEAM (carmustine, etoposide, cytarabine, and melphalan) is widely recognized as the predominant conditioning regimen due to its satisfactory efficacy and tolerability. Nevertheless, shortages of carmustine and melphalan have compelled clinicians to explore alternative conditioning regimens. The aim of this study was to compare the toxicity and transplant outcomes following BEAM, CBV (carmustine, etoposide, cyclophosphamide), BuMel (busulfan, melphalan), and BendaEAM (bendamustine, etoposide, cytarabine, melphalan). We retrospectively analyzed data from 213 patients (CBV 65, BuMel 42, BEAM 68, BendaEAM 38) with R/R lymphomas undergoing AHCT between 2014 and 2020. Multivariate models were employed to evaluate toxicity and transplant outcomes based on conditioning type. Among grade III to IV toxicities, oral mucositis was more frequently observed with BuMel (45%) and BendaEAM (24%) compared to BEAM (15%) and CVB (6%, <em>P</em> ≤ .001). Diarrhea was more common with BendaEAM (42%) and less frequent with BuMel (7%, <em>P</em> = .01). Acute kidney injury was only found after BendaEAM (11%). Febrile neutropenia and infectious complications were more frequent following BendaEAM. Frequencies of other treatment-related toxicities did not significantly differ according to conditioning type. BendaEAM (odds ratio [OR] 3.07, <em>P</em> = .014) and BuMel (OR 4.27, <em>P</em> = .002) were independently associated with higher grade III to IV toxicity up to D+100. However, there were no significant differences in relapse/progression, nonrelapse mortality, progression-free survival, or overall survival among the four regimens. BuMel and BendaEAM were associated with a higher rate of grade III to IV toxicity. Carmustine-based regimens appeared to be less toxic and safer; however, there were no significant differences in transplant outcomes.
