Hypothesis

What are the independent prognostic factors for the survival of patients with endometrial stromal sarcoma?

Conclusion

Age, race, stage, and grade of disease are important independent prognostic factors for survival in patients with endometrial stromal sarcoma.

Supporting Evidence

  • Patients with stage I–II disease had a 5-year disease-specific survival (DSS) of 89.3%.
  • Blacks had a worse DSS compared to other races (62.5% vs 78.1%).
  • Those who underwent primary hysterectomy had a significant benefit over those who did not (78.5% vs 42.4%).
  • 5-year DSS for grades 1, 2, and 3 disease were 91.4%, 95.4%, and 42.1%, respectively.

Takeaway

This study looked at women with a rare type of uterine cancer and found that things like age and how advanced the cancer is can really affect how long they live.

Methodology

Data were abstracted from the SEER database and analyzed using Kaplan–Meier and Cox proportional hazards models.

Potential Biases

Previous studies were limited by small sample sizes and potential biases from single academic institutions.

Limitations

The study lacked information on surgeon specialty, residual disease status, hormone receptor status, and prior treatments.

Participant Demographics

Median age was 52 years, with a range from 17 to 96 years; 66.5% were White, 13.7% Black, 9.9% Hispanic, and 8.4% Asian.
