Identifying risk factors for carcinomatous meningitis (CM) in solid tumor patients is crucial for prevention. Advanced tumor stage (M1), undifferentiated tumors, and bone metastases are identified as independent risk factors for CM.

Area of Science:

  • Neuro-oncology
  • Clinical Oncology
  • Cancer Epidemiology

Background:

  • Carcinomatous meningitis (CM) is a serious neurological complication of solid tumors.
  • Identifying predictive markers for CM is essential for early detection and prevention.

Purpose of the Study:

  • To identify risk markers for carcinomatous meningitis (CM) in patients with solid tumors.
  • To analyze trends in CM incidence over a 20-year period.

Main Methods:

  • Retrospective study of 41 patients with cytologically confirmed CM from 1976 to 1996.
  • Analysis of clinical data, tumor histology, dissemination, and treatment using uni- and multivariate statistics.
  • Calculation of CM incidence rates in 5-year intervals.

Main Results:

Related Experiment Videos

  • Breast, lung (small cell), and urinary cancers were the most common primary tumors.
  • M1 dissemination and undifferentiated tumors were associated with a shorter time to CM.
  • CM incidence increased for urinary cancers and decreased for breast cancer over the study period.
  • Bone metastases, though frequent, did not shorten the time to CM.

Conclusions:

  • M1 dissemination and undifferentiated tumors are independent risk factors for CM.
  • Neoadjuvant chemotherapy may potentially reduce the risk of meningeal dissemination.
  • Further prospective trials are needed to identify additional risk factors for CM.
