Background Pancreatic cancer remains one of the most difficult cancers to treat with the poorest prognosis. The key to improving survival rates in this disease is early detection and monitoring of... Circulating tumor cells (CTC) and KRAS mutant circulating free DNA (cfDNA) detection in peripheral blood as biomarkers in patients diagnosed with ... Topic: Immunotherapy / Translational Research / Non-Small Cell Lung Cancer / Basic Principles in the Management and Treatment (of cancer) / Therapy medwireNews : Patients with adenocarcinoma of the lung who harbour TP53 and KRAS mutations have a better response to treatment with programmed cell death protein 1 (PD-1) inhibitors than those with wild-type forms of the genes, research shows. Oncogenic mutations in Kirsten rat sarcoma viral oncogene homolog (KRAS) occur in 15%-30% of non-small cell lung cancer (NSCLC). However, despite decades of intensive research, there is still no direct KRAS inhibitor with clinically proven efficacy.

Genetic disruption of oncogenic Kras sensitizes lung cancer cells to Fas receptor-mediated apoptosis Haiwei Moua,1, Jill Mooreb,1, Sunil K. Maloniac,1, Yingxiang Lib,d, Deniz M. Ozataa, Soren Hougha, Chun-Qing Songa, Jan 07, 2014 · CINCINNATI—University of Cincinnati Cancer Institute researchers have found that using therapies specifically targeting the molecular profile of non-small-cell lung cancer with the mutated cancer-causing protein KRas is the most effective treatment strategy for patients with the condition. Of note, treatment of KRAS-mutant LUAD with HG106 in several lung cancer preclinical mouse models led to marked tumor suppression and prolonged mouse survival. Overall, our findings reveal that KRAS-mutant LUAD cells are vulnerable to SLC7A11 inhibition, providing promising therapeutic approaches to the treatment of this currently incurable ...

Summary of "KRAS-mutant non-small cell lung cancer: Converging small molecules and immune checkpoint inhibition.". KRAS is the most frequent oncogene in non-small cell lung cancer (NSCLC), a molecular subset characterized by historical disappointments in targeted treatment approaches such as farnesyl transferase inhibition, downstream MEK inhibition, and synthetic lethality screens. Lung Cancer and EGFR Exon 19 Deletion Mutations . This material will help you understand: • the basics of lung cancer • the role of the EGFR gene in lung cancer • if there are any drugs that might work better if you have certain changes in the EGFR gene . What is lung cancer? Lung cancer is a type of cancer that starts in the lungs. Nov 18, 2019 · The KRAS G12R mutation results in unique changes to the KRAS protein structure, the researchers found. “For nearly four decades, the cancer research community has searched for a therapy for all KRAS mutant cancers, and has failed,” Der said. “Now, an emerging concept in targeting mutant KRAS for cancer treatment is that there may be ... KRAS mutations are the most frequent oncogenic aberrations to occur in NSCLCs and activation of KRAS in lung cancer induces the NF-κB pathway and release of IL22 . KRAS mutant cancers also portend poor prognosis and chemoresistance. Unfortunately, targeted therapies for KRAS mutant cancer have not NEW YORK – The US Food and Drug Administration expanded the indication for AstraZeneca and Merck's olaparib (Lynparza) as a maintenance treatment for certain metastatic pancreatic cancer patients identified with the help of a companion diagnostic, the two drugmakers announced on Monday.

To date, the most optimal treatment of KRAS‐mutant lung cancer remains controversial. Before 2018, in China, pemetrexed plus platinum is still the first‐line treatment for advanced NSCLC patients. In recent years, tremendous efforts have been invested in elucidating the most optimal treatment strategy for KRAS‐mutant NSCLC patients.
