Summary

This summary is machine-generated.

This study developed a prognostic nomogram for localized papillary renal cell carcinoma (pRCC) patients. The nomogram incorporates sarcopenia, body composition, tumor diameter, and surgical technique to predict cancer progression, aiding survival prognostication.

Area Of Science

  • Urology
  • Oncology
  • Radiology

Background

  • Subclassification removal for papillary renal cell carcinoma (pRCC) impacts survival prognostication post-surgery.
  • Sarcopenia is a known prognostic factor in renal cell carcinoma (RCC) patients.
  • Body composition parameters require comprehensive investigation for localized pRCC survival prediction.

Purpose Of The Study

  • To investigate the survival prediction of body composition parameters for localized pRCC.
  • To develop a prognostic model for predicting progression-free survival in localized pRCC patients.

Main Methods

  • Retrospective analysis of 105 localized pRCC patients.
  • Measurement of skeletal muscle index (SMI), subcutaneous adipose tissue (SAT), and perirenal adipose tissue (PRAT) from preoperative CT scans.
  • Development of a prognostic nomogram using Cox regression analysis and validated with C-index and ROC curves.

Main Results

  • Sarcopenia was present in 74.29% of patients.
  • Multivariate analysis identified sarcopenia, SAT, PRAT, tumor diameter, and surgical technique as independent risk factors for progression.
  • The developed prognostic nomogram demonstrated good predictive performance with a C-index of 0.831.

Conclusions

  • A prognostic nomogram integrating sarcopenia, SAT, PRAT, tumor diameter, and surgical technique can predict progression in localized pRCC.
  • This nomogram aids in survival prognostication for localized pRCC patients.
  • Further external validation is required for clinical implementation.
