Women with diffuse malignant peritoneal mesothelioma (DMPM) survive longer than men. This improved survival in women may be linked to favorable clinical and histopathological factors.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Pathology

Background:

  • Diffuse malignant peritoneal mesothelioma (DMPM) is a rare and historically fatal cancer.
  • Female patients with DMPM have demonstrated better survival outcomes, though the reasons remain unclear.

Purpose of the Study:

  • To compare the survival rates of men and women with DMPM.
  • To identify potential clinical and histopathological factors contributing to survival differences.

Main Methods:

  • Survival analysis of 34 men and 28 women treated with cytoreduction and intraperitoneal chemotherapy for DMPM.
  • Univariate analysis of 25 clinicopathological variables.

Main Results:

  • Women exhibited a 5-year survival rate of 63% with median survival not reached, compared to 42% and 32 months for men (P=0.045).

  • Women underwent more extensive prior surgery and had less peritoneal disease at cytoreduction.
  • Tumors in women more frequently displayed small nuclear size and a granular chromatin pattern.

    • Conclusions:

    • Women with DMPM demonstrate superior survival compared to men.
    • Favorable clinical and histopathological features in women may explain their improved prognosis.
