Summary

Combined radio-chemotherapy offers meaningful palliation for select patients with AIDS-related lymphomatous meningitis or primary central nervous system lymphoma. This aggressive treatment approach shows survival benefits comparable to non-AIDS patients.

Area of Science:

  • Oncology
  • Neurology
  • Infectious Diseases

Background:

  • AIDS-related lymphomatous meningitis (LM) and primary central nervous system lymphoma (PCNSL) are severe complications in HIV-infected individuals.
  • Treatment options for these conditions in the context of AIDS are limited, often with poor prognoses.

Purpose of the Study:

  • To evaluate the efficacy of combined radio-chemotherapy in patients diagnosed with AIDS-related LM or PCNSL.
  • To assess treatment outcomes, including survival and tumor progression, in this patient population.

Main Methods:

  • A cohort of patients with AIDS and either LM or PCNSL underwent standardized evaluations and treatment protocols.
  • Treatment strategies included limited-field irradiation, concurrent systemic chemotherapy, and intraventricular methotrexate, with salvage options for treatment failures.
  • PCNSL patients were stratified into comfort care, whole brain radiotherapy, or combined radio-chemotherapy groups based on specific clinical criteria.

Main Results:

  • In the LM group, treated patients who responded showed a median survival of 6 months, compared to 1 month for non-responders and 1 month for the untreated group.
  • In the PCNSL group, median survival was 0.5-3 months for comfort care, 1.5-5 months for whole brain radiotherapy, and 10-18 months for combined radio-chemotherapy.
  • The combined radio-chemotherapy group for PCNSL demonstrated the most favorable survival outcomes.

Conclusions:

  • Combined radio- and chemotherapy is a viable and appropriate treatment for a select group of patients with AIDS-related LM or PCNSL.
  • This aggressive therapeutic approach can achieve meaningful palliation and survival benefits, comparable to those observed in non-AIDS patients with similar conditions.
