Summary

This summary is machine-generated.

A new nomogram accurately predicts survival for anal squamous cell carcinoma (ASCC) patients treated with chemoradiotherapy. It also identifies male patients who may benefit from surgery, aiding personalized treatment decisions.

Area Of Science

  • Oncology
  • Medical Statistics

Background

  • Anal squamous cell carcinoma (ASCC) is a rare malignancy.
  • Chemoradiotherapy is a standard treatment for ASCC.
  • Predicting prognosis and identifying optimal treatment strategies remain challenging.

Purpose Of The Study

  • To develop and validate a nomogram for predicting overall survival in ASCC patients.
  • To identify ASCC patients who may benefit from surgical intervention.
  • To compare the nomogram's performance with the AJCC staging system.

Main Methods

  • Retrospective analysis of 4697 ASCC patients from the SEER database.
  • Development of a nomogram using LASSO and Cox regression.
  • Internal and external validation of the nomogram's discriminatory and calibration abilities.
  • Decision curve analysis and subgroup analysis to assess clinical utility and identify surgical candidates.

Main Results

  • Age, sex, tumor size, and AJCC stage were identified as independent prognostic factors.
  • The nomogram demonstrated strong predictive accuracy and outperformed the AJCC staging system.
  • Risk stratification revealed significant survival differences among patient subgroups.
  • Subgroup analysis indicated potential benefit from surgery in male ASCC patients.

Conclusions

  • The developed nomogram is a valuable tool for predicting long-term prognosis in ASCC patients.
  • The nomogram aids in personalized treatment decisions, particularly regarding surgical intervention for specific patient groups.
  • Further research may explore the role of surgery in male ASCC patients.
