Background: Circulating tumor cells (CTCs) correlate with adverse prognosis in patients with breast, colorectal, lung, and prostate cancer. Little data are available for renal cell carcinoma (RCC).

Materials And Methods: We designed a multicenter prospective observational study to assess the correlation between CTC counts and progression-free survival (PFS) in patients with metastatic RCC treated with an antiangiogenic tyrosine kinase inhibitor as a first-line regimen; overall survival (OS) and response were secondary objectives.

Importance: There exists considerable biological and clinical variability between histologic variants of metastatic renal cell carcinoma (mRCC). Data reporting on patterns of metastasis in histologic variants of mRCC are sparse.

Objective: To characterize sites of metastasis and their association with survival across the 3 most common histologic variants of mRCC: clear cell (ccRCC), papillary (pRCC), and chromophobe (chrRCC).

Article Synopsis
  • Previous studies showed that steady-state Z-endoxifen levels (ENDOss) are linked to better cancer outcomes for women on tamoxifen.
  • A study involving 203 Caucasian women evaluated the reliability of two methods for measuring CYP2D6 activity: genetic testing and a urinary dextromethorphan test.
  • It was found that the urinary log(DM/DX) test was a better predictor of ENDOss than genetic testing, highlighting the importance of considering this approach in breast cancer treatment.

Background: The use of cytoreductive nephrectomy (CN) selectively for patients who show a favorable response to upfront systemic therapy may be an approach to select optimal candidates with metastatic renal cell carcinoma (mRCC) who are most likely to benefit.

Objective: We sought to characterize outcomes of deferred CN (dCN) after upfront sunitinib, outcomes relative to sunitinib alone, and outcomes of CN followed by sunitinib.

Design, Setting, And Participants: We used the prospectively maintained International mRCC Database Consortium (IMDC) database to identify patients with newly diagnosed mRCC (2006-2018).

Recently cabozantinib, a tyrosine kinase inhibitor with activity against VEGF, MET, AXL, and downregulating cathepsin K in vitro, has been proposed for the treatment of advanced clear and non-clear renal cell carcinomas. Since it is well known that cathepsin K is expressed in the majority of MiT family translocation renal cell carcinomas, we investigated cathepsin K, MET, AXL, and VEGF in a large series of those tumours, looking for possible predictive markers. We collected the clinicopathological features of 34 genetically confirmed MiT family translocation renal cell carcinomas [26 Xp11 and 8 t(6;11) renal cell carcinomas] and studied them using an immunohistochemical panel including PAX8, cathepsin K, HMB45, Melan-A, CD68 (PG-M1), CK7, CA9, MET, AXL and by FISH for VEGFA and MET.
