Abstract
Summary: TP53 alterations portend extremely poor prognosis in patients with mantle cell lymphoma treated with standard treatment modalities. We reviewed outcomes of 42 patients with available TP53 status who had received a reduced‐intensity or non‐myeloablative allogeneic haematopoietic cell transplant at our institution. We demonstrated a 2‐year overall survival and progression‐free survival of 78% [95% confidence interval (CI) 60–88] and 61% (95% CI 43–75), respectively. The 2‐year cumulative incidences of relapse and non‐relapse mortality were 19% and 20%, respectively. Importantly, there is no significant difference among patients with and without TP53 alterations, suggesting for the first time a beneficial treatment modality for these high‐risk patients.
