The emergence of chimeric antigen receptor (CAR) T cell therapy has shifted the paradigm of malignant tumor treatment, especially the advent of CD19-directed CAR-T cell therapy for the treatment of relapsed/refractory (R/R) B-cell malignancies. Although CAR-T cell therapy has promising effects, some patients are resistant to this treatment, leaving them with limited options. Therefore, strategies to overcome resistance to CAR-T cell therapy are needed.

Article Synopsis
  • - Central nervous system lymphoma (CNSL) is a severe type of cancer, and orelabrutinib, a new oral medication, is being tested to see how effective and safe it is for treating patients with this disease.
  • - In a study of 23 patients, 100% of those with newly diagnosed CNSL showed improvement using orelabrutinib, while 60% of patients with relapsed cases also benefited from the treatment, with high rates of response and survival at six months.
  • - Overall, orelabrutinib-based regimens proved to be effective and generally well-tolerated, suggesting that these treatments could become a new option for managing CNSL.

Article Synopsis
  • Extranodal natural killer (NK)/T-cell lymphoma, nasal type (ENKTL) is a subtype of T-cell lymphoma with a poor outlook and no standard treatments for patients who relapse or do not respond to therapy.
  • A case study of three patients showed that a new treatment regimen combining the PD-1 antibody toripalimab, chidamide, etoposide, and thalidomide led to significant improvements, with two patients achieving complete remission and one showing partial remission.
  • While the treatment had manageable side effects like leukocytopenia and anemia, the findings suggest that the PCET regimen could be an effective option for treating R/R ENKTL and deserves more research.
