While disease-related factors are well-known, the impact of host-related factors like nutritional status remains less defined. We aimed to evaluate the prognostic value of the prognostic nutritional index (PNI) and other factors in lymphoma patients undergoing ASCT. Methods: We conducted a single-center retrospective cohort study including adult patients with Hodgkin and non-Hodgkin lymphoma who underwent ASCT between January 2015 and December 2023. Pre-transplant clinical, laboratory, and transplant-related variables were analyzed. The prognostic nutritional index (PNI) was calculated using serum albumin and absolute lymphocyte count and dichotomized according to the cohort median. Progression-free survival (PFS) and overall survival (OS) were evaluated using Kaplan\u2013Meier and Cox regression analyses. We conducted a retrospective single-center cohort study including adult patients with Hodgkin and non-Hodgkin lymphoma who underwent ASCT between January 2015 and December 2023. Results: A total of 43 patients were included. Median age was 38 years, and 72.1% were male. Patients transplanted in complete remission (CR) had significantly longer PFS compared with those transplanted in partial remission (PR) (log-rank p = 0.022). Patients with higher pre-ASCT PNI demonstrated significantly improved PFS (median 45 vs. 7 months; log-rank p = 0.021). In multivariable Cox regression analysis, both higher PNI (HR 0.39; 95% CI 0.16\u20130.97; p = 0.043) and complete remission prior to ASCT (HR 0.41; 95% CI 0.17\u20130.98; p = 0.046) remained independently associated with improved PFS. Higher infused CD34+ (hematopoietic stem cell) dose was associated with shorter hospitalization but showed no statistically significant association with engraftment kinetics or survival. No variable was independently associated with OS, likely due to the limited number of death events. Conclusions: Pre-transplant prognostic nutritional index and disease response independently predict progression-free survival after ASCT in lymphoma. These findings highlight the complementary role of host-related and disease-related factors in transplant outcomes and suggest that PNI may serve as a practical tool for pre-transplant risk stratification and patient optimization. Given the small sample size and limited number of events, these findings should be interpreted with caution.<\/jats:p>","DOI":"10.3390\/jcm15093549","type":"journal-article","created":{"date-parts":[[2026,5,7]],"date-time":"2026-05-07T09:03:37Z","timestamp":1778144617000},"page":"3549","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Pre-Transplant
