Core Tip

Core tip: Some refractory metastatic solid tumors including renal, ovarian and even colon cancers may respond well to allogeneic hematopoietic stem cell transplantation (allo-HSCT) with reduced intensity conditioning (RIC). Their lower toxicity profiles and lower non-relapse mortality rates constitute the advantages of RIC. The use of allo-HSCT with RIC or non-myeloablative regimens can be a feasible option among fragile patients, such as geriatric patients and patients with comorbidities. Future studies are needed for a clear-cut understanding of the mechanisms of graft-versus-leukemia and graft-versus-tumor effects of donor T-cells and their subsets in order to optimize the efficacy of such treatment modalities in patients with refractory solid tumors.
