Genentech announced that the phase III SKYSCRAPER-02 study, evaluating the investigational anti-TIGIT immunotherapy tiragolumab plus Tecentriq (atezolizumab) and chemotherapy (carboplatin and etoposide) as a first-line treatment for extensive-stage small cell lung cancer (ES-SCLC), did not meet its co-primary endpoint of progression-free survival.

Patients with metastatic colorectal cancer harboring BRAF V600E mutations benefitted from first-line treatment with the targeted therapies Braftovi(encorafenib) and Erbitux(cetuximab) plus a mFOLFOX6 chemotherapy regimen, according to results from the phase III BREAKWATER trial led by researchers at the University of Texas MD Anderson Cancer Center.
A phase II trial found that for patients with HER2+ metastatic colorectal cancer, dual HER2-inhibitor therapy can be a similarly efficacious but less toxic alternative to EGFR inhibitor therapy. Exploratory analysis suggests greater HER2 amplification in a tumor may be associated with greater clinical benefit of dual HER2 inhibitor vs EGFR inhibitor therapy.
A new statistical tool that combines multiple clinical and pathologic factors with a patient’s 21-gene Oncotype DX Breast Recurrence Score result provides more accurate estimates about that patient’s breast cancer prognosis and their potential benefit from chemotherapy than either the Recurrence Score result or clinical factors alone, a SWOG Cancer Research study found.
Despite steady progress in reducing overall cancer mortality rates, cancer incidence in women is rising, according to the American Cancer Society’s “Cancer Statistics, 2025” report. Incidence rates in women 50-64 years of age have surpassed those in men, and rates in women under 50 are now 82% higher than their male counterparts, up from 51% higher in 2002. In 2021, for the first time, lung cancer incidence was higher in women under 65 than in men.
