Surgical resection (HR 0.41) and radiation (HR 0.39) significantly improved survival in renal sarcoma, with angiosarcoma subtype having a 12.65-fold higher mortality risk.
Histologic subtype is the most critical prognostic factor for renal sarcoma, with dramatic survival differences between subtypes (e.g., 94.4% 3-year survival for clear cell vs 19.0% for angiosarcoma), mandating histology-specific treatment protocols.
Absolute Event Rate: 0% vs 0%
We analyzed survival rates and prognostic factors for renal sarcoma using Japan's National Cancer Registry data. We conducted a retrospective cohort study of patients diagnosed with renal sarcoma (2016-2019). Prognostic factors were evaluated using Cox regression analyses. Among 235 patients, female sex (HR, 0.43; 95% CI, 0.23-0.83; p = 0.012), older age (≥60 years: HR, 5.87; p p p p = 0.004) and radiation therapy (HR, 0.39; p = 0.010) were associated with improved survival. Histologic subtype is the most critical prognostic factor for renal sarcoma in Japan's aging population, with dramatic survival differences: clear cell sarcoma (94.4% 3-year survival) versus angiosarcoma (19.0%). This heterogeneity mandates histology-specific treatment protocols rather than organ-based approaches, with particular relevance for aging societies in Asia.
