Inhibition of autocrine epidermal growth factor receptor (EGFR) signaling has been shown to reduce plasma calcium and PTHrP concentrations in two lung squamous cell carcinoma xenograft models of HHM.
EGFR gene copy numbers were assessed by FISH and evaluated as predictors of EGFR-TKI efficacy in 71 patients with advanced squamous cell lung cancer who received gefitinib or erlotinib as a second-line or higher therapy.
How sensitive are epidermal growth factor receptor-tyrosine kinase inhibitors for squamous cell carcinoma of the lung harboring EGFR gene-sensitive mutations?
Therefore, in contrast to advanced LADC, EGFR mutation testing may not be necessarily performed upfront in advanced LSQC because not only the mutation rate is low, but also the predictive value is insufficient.
Cell membrane CD44v6 levels in squamous cell carcinoma of the lung: association with high cellular proliferation and high concentrations of EGFR and CD44v5.
The Q787Q EGFR polymorphism allows stratifying lung squamous cell carcinoma patients and could be an independent prognostic marker, particularly among those in stages I and II.
Efficacy of postoperative radiotherapy in patients with pathological stage N2 epidermal growth factor receptor wild type adenocarcinoma and squamous cell carcinoma lung cancer.
However, the application of TKIs for lung squamous cell carcinoma (SCC), the second largest pathological subtype of NSCLC, remains controversial because available data for the EGFR mutation profile and frequency in SCC patients are limited.
