Treatments and clinical outcomes in stage II colon cancer patients with 12-gene Oncotype DX Colon Recurrence Score® assay-guided therapy: real-world data.

Background: The 12-gene Oncotype DX Colon Recurrence Score® result quantifies the recurrence risk in stage II/III colon cancer (CC). This real-world study investigated stage II CC patients whose treatment decisions incorporated the Recurrence Score® (RS) result.

Materials And Methods: This retrospective analysis of a prospectively designed cohort included all stage II, mismatch repair-proficient CC patients who underwent 12-gene testing through Clalit between January 2011 and December 2016 and had available data with a minimum 3-year follow-up.

ALK Inhibitors or Chemotherapy for Third Line in ALK-positive NSCLC? Real-world Data.

Objectives: ALK inhibitors (ALKi) are the standard-of-care treatment for metastatic ALK-rearranged non-small cell lung cancer (NSCLC) in the first- and second-line setting. We conducted a real-world multi-institutional analysis, aiming to compare the efficacy of third-line ALKi versus chemotherapy in these patients.

Methods: Consecutive ALK-positive metastatic NSCLC patients treated with at least one ALKi were identified in the working databases of 7 Israeli oncology centers (the full cohort).

Efficacy and Safety of BRAF Inhibitors With or Without MEK Inhibitors in BRAF-Mutant Advanced Non-Small-Cell Lung Cancer: Findings From a Real-Life Cohort.

Background: Real-life comparative data on BRAF inhibitors (BRAFi) and BRAFi + MEK inhibitors (MEKi) combination in BRAF-mutant (BRAFm) non-small-cell lung cancer (NSCLC) is lacking.

Patients And Methods: Consecutive BRAFm advanced NSCLC patients (n = 58) treated in 9 Israeli centers in 2009-2018 were identified. These were divided according to mutation subtype and treatment into groups A1 (V600E, BRAFi; n = 5), A2 (V600E, BRAFi + MEKi; n = 15), A3 (V600E, no BRAFi; n = 7), B1 (non-V600E, BRAFi ± MEKi; n = 7), and B2 (non-V600E, no BRAFi; n = 23); one patient received both BRAFi and BRAFi + MEKi.

Efficacy and Safety of ALK Tyrosine Kinase Inhibitors in Elderly Patients with Advanced ALK-Positive Non-Small Cell Lung Cancer: Findings from the Real-Life Cohort.

Background: Little is known regarding the anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitor (TKI) efficacy and safety in the elderly.

Objectives And Methods: Consecutive patients (n = 53) with ALK-positive advanced non-small cell lung cancer treated with an ALK TKI were identified through internal databases of three cancer centers and divided into groups A (< 65 years old; n = 34) and B (≥65 years old; n = 19). Progression-free survival (PFS), ALK TKI safety and overall survival (OS) were assessed.

Sidedness Matters: Surrogate Biomarkers Prognosticate Colorectal Cancer upon Anatomic Location.

Background: Anatomic location of primary tumors across the colon correlate with survival in the metastatic setting, whereas left-sided tumors may exhibit superior survival compared with right-sided tumors. The Oncotype Recurrence Score (RS) assay is a clinically validated predictor of recurrence risk in patients with stage II colorectal cancer (CRC). Previous studies had indicated that without adjuvant chemotherapy, CDX2-negative stage II CRC tumors are associated with a lower rate of disease-free survival than CDX2-positive stage II CRC tumors.
