Clinical characteristics and survival outcomes of TFE3-rearranged renal cell carcinoma: a retrospective study compared with clear cell renal cell carcinoma using propensity score matching
To compare clinicopathologic and survival outcomes between TFE3-rearranged renal cell carcinoma (TFE3-rRCC) and clear cell renal cell carcinoma (ccRCC), and to evaluate the feasibility of partial nephrectomy for localized TFE3-rRCC.
Key Findings:
62 patients with TFE3-rRCC were included, median age at diagnosis was 33 years.
61.3% of patients were asymptomatic; common symptoms included hematuria and abdominal pain.
56.5% underwent radical nephrectomy, while 43.5% underwent partial nephrectomy.
The most common histological T stage was T1a (40.3%).
Survival rates and comparisons to ccRCC outcomes need to be included for context.
Interpretation:
The clinical behavior of TFE3-rRCC varies significantly, with some studies indicating aggressive behavior while others suggest outcomes similar to ccRCC, particularly in early-stage cases, highlighting the need for further research.
Limitations:
The study is retrospective and conducted at a single center, which may limit generalizability and the applicability of findings to broader populations.
Limited evidence exists regarding nephron-sparing surgery for TFE3-rRCC, which may affect treatment decisions.
Conclusion:
Further research is needed to clarify the management of localized TFE3-rRCC and its outcomes compared to ccRCC.
