Abstract 3433

Background

Patients (pts) with metastatic renal cell carcinoma (mRCC) may present with primary metastases (synchronous disease) or develop metastases during follow-up (metachronous disease). The impact of timing of metastatic disease outbreak on outcomes from targeted therapy (TKI) is unclear.

Methods

We used the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) to assess overall survival (OS) and time to treatment failure (TTF) on first line TKI, and performed Cox regression analyses comparing synchronous (metastases ≤ 3 mo of initial diagnosis of cancer) vs metachronous disease (metastasis diagnosed post initial diagnosis, evaluated by intervals >3-12 mo, >1-2 yrs, >2-7 yrs, and >7yrs).

Results

In 7386 pts with mRCC treated with first line TKI, 3906 pts (53%) had synchronous and 3480 pts (47%) had metachronous metastases. Synchronous vs metachronous disease by intervals >3-12 mo, >1-2 yrs, >2-7 yrs, >7yrs correlated with lower age at TKI initiation (mean 61 yrs vs 61, 62, 63, 66 yrs, respectively, p 1∼2yrs638(9%)40130.2(26.7-32.5)0.84(0.76-0.94)0.0026355648.0(7.3-8.9)0.99(0.90-1.08)0.767>2∼7yrs1155(16%)72934.8(32.4-38.1)0.76(0.70-0.83)

Conclusions

Timing of metastases post initial RCC diagnosis impacts outcome with targeted therapy in mRCC. This may need to be taken into consideration in clinical trial designs.
