Abstract

Anti-epidermal growth-factor receptor (EGFR) monoclonal antibody (MoAb) treatment for chemotherapy refractory or metastatic colorectal cancer has obtained great achievement. However, not every colorectal patient responds to such molecular-targeted agent well. Biomarkers associated with anti-EGFR resistance are not limited to KRAS mutation up to now. It was recently reported that cross-talking molecular effectors interacted with EGFR-related pathway were also negative predictor for anti-EGFR treatment. However, the limited data, controversial results, and contradictories between in vitro and clinical studies restrict the clinical application of these new biomarkers. Although the current theory of tumor microenvironment supported the application of multi-target treatment, the results from the clinical studies were less than expected. Moreover, WHO or RECIST guideline for response assessment in anti-EGFR MoAb treatment was also queried by recent AIO KRK-0306 trial. This review focuses on these controversies, contradictories, and limitations, in order to uncover the unmet needs in current status of anti-EGFR MoAb treatment in colorectal cancer.

Adjuvante Immuntherapie verlängert Leben bei RCC

25.04.2024 Nierenkarzinom Nachrichten

Nun gibt es auch Resultate zum Gesamtüberleben: Eine adjuvante Pembrolizumab-Therapie konnte in einer Phase-3-Studie das Leben von Menschen mit Nierenzellkarzinom deutlich verlängern. Die Sterberate war im Vergleich zu Placebo um 38% geringer.

Alectinib verbessert krankheitsfreies Überleben bei ALK-positivem NSCLC

25.04.2024 NSCLC Nachrichten

Das Risiko für Rezidiv oder Tod von Patienten und Patientinnen mit reseziertem ALK-positivem NSCLC ist unter einer adjuvanten Therapie mit dem Tyrosinkinase-Inhibitor Alectinib signifikant geringer als unter platinbasierter Chemotherapie.
