NCI-MATCH precision medicine clinical trial releases new findings

(ECOG-ACRIN Cancer Research Group) The released data is from three treatment arms, all single-arm phase 2 studies: the drug taselisib in patients with mutations in the PIK3CA gene (Arm I); the drug ado-trastuzumab emtansine (T-DM1) in patients with HER2-overexpressing tumors (Arm Q); and the drug AZD4547 in patients with mutations in the FGFR pathway (Arm W).

In conclusion, our WGCNA analysis identified candidate prognostic biomarkers for further basic and clinical researches. Introduction Breast cancer is a frequently diagnosed malignancy and the leading cause of cancer death among females around the world, accounting for 24% of cancer diagnoses and 15% of cancer deaths in females. According to Global Cancer Statistics 2018, there will be nearly 2.1 million new cases diagnosed globally, with ~62 thousand deaths. The incident rates of breast cancer increased in most developing countries during last decades, resulting from a combination of social and economic factors, incl...

In this study, we confirm our initial findings from the proteomic screen and demonstrate that LASP1 can interact with both eIF4A and eIF4B. Importantly, the LASP1-eIF4A and LASP1-eIF4B interaction is shown to be CXCL12-dependent. In addition, the ability of CXCR4 to impact the phosphorylation of eIF4F regulatory proteins is provided. Taken together, we hypothesize that activation of CXCR4 can promote eIF4F complex formation and activity through LASP1 and cell signaling. As a result, the translation of oncogenic proteins is promoted thereby mediating an invasive and metastatic phenotype commonly associated with CXCR4. Mate...

ConclusionsCirculating formate is reduced in HER2+ breast cancer, non-small cell lung cancer and highly obese patients relative to healthy controls. Further studies are required to determine the relevance of these observations in other cancer types and diseases.

Conclusion and Perspective With in-depth understandings of antibodies, linkers, and payloads, ADCs have also achieved great development. The linkage strategy and target diversity have already improved the delivery of the payloads to tumor tissues and reduced exposure to normal tissues. With the development of payloads, some novel potent payloads are used by ADCs, which allows researchers to exploit novel linkers to attach the antibody and payloads without disturbing their potency (Dragovich et al., 2018). Furthermore, some irrelevant antigen-target ADCs also may exert toxicity to tumor cells due to the vascular gap of tum...

However, a direct comparison between the results of HER2 immunohistochemistry (IHC) and next-generation sequencing (NGS)-based cancer panel tests has not been explored in GC. We aimed to determine optimal thresholds of HER2 overexpression to be detected by NGS with the data of 168 metastatic GC cases with known expression leve...

AbstractBackgroundWe recently reported the clinical significance of intratumoral HER2 heterogeneity on trastuzumab efficacy using surgical specimens; patients with homogeneously HER2 positive gastric cancer benefitted more from trastuzumab. However, the majority of patients are diagnosed by endoscopic biopsy, and surgical specimens are not available in these patients. The aim of this study is to verify clinical significance of HER2 heterogeneity on trastuzumab efficacy using biopsy specimens.MethodsEighty-seven patients, who received trastuzumab-based chemotherapy and whose endoscopic biopsy specimens were available for HE...
