Combining immune checkpoint inhibition plus tyrosine kinase inhibition as first and subsequent treatments for metastatic renal cell carcinoma.

Background: Immune checkpoint inhibitor/tyrosine kinase inhibitor (ICI/TKI) combinations are a new standard of care for the initial treatment of metastatic renal cell carcinoma (mRCC). Their efficacy and toxicity beyond the first-line setting remain poorly defined.

Methods: We retrospectively reviewed charts for 85 adults with mRCC of any histology receiving combination of ICI/TKI in any line of treatment at two academic centers as of 05/01/2020.

Salvage nivolumab and ipilimumab after prior anti-PD-1/PD-L1 therapy in metastatic renal cell carcinoma: A meta-analysis.

Background: Salvage nivolumab and ipilimumab after prior anti-PD-1/PD-L1 therapy is frequently used off-label for clear cell metastatic renal cell carcinoma (mRCC). However, limited data are available to guide such therapy. We performed a meta-analysis to characterize further the safety and efficacy of salvage nivolumab and ipilimumab.

Serum free light chains in myeloma patients with an intact M protein by immunofixation: potential roles for response assessment and prognosis during induction therapy with novel agents.

The ascertainment of serum free light chain (sFLC) levels has been shown to be valuable in screening for the presence of plasma cell dyscrasia as well as for baseline prognosis in newly diagnosed patients. For patients with amyloidosis and those with oligo-secretory or non-secretory multiple myeloma (MM), serial measurement of sFLC has also been shown to be valuable in monitoring disease status. However, in patients with a measureable, intact monoclonal protein by immunofixation (M protein), the serial measurement of sFLC remains undefined and is currently not recommended in professional guidelines.
