A phase Ib, open-label, dose-escalation study of the safety and pharmacology of taselisib (GDC-0032) in combination with either docetaxel or paclitaxel in patients with HER2-negative, locally advanced, or metastatic breast cancer

ConclusionsTaselisib in combination with a taxane has a challenging safety profile. Despite evidence of antitumor activity, the benefit –risk profile was deemed not advantageous. Further development is not planned.

This study investigates the potential of the EGF signalling pathway to alter PD-L1 expression in parental and L- or A-resistant HER2+ BC cell lines to examine the pre-clinical rationale for the combination of anti-PD-1/PD-L1 agents and TKIs in HER2+ BC.MethodsParental (HCC1954-P, SKBR3-P) and TKI-resistant HER2+ breast cancer cell lines (L-resistant HCC1954-L, A-resistant SKBR3-A) were treated with the EGFR ligand EGF (10ng/ml) alone, L (1 µM) alone or the combination of EGF and L for 24 hours. Protein lysates were generated. PD-L1 (CST E1L3N), EGFR (ThermoFisher MS665) and pEGFR y1068 (Millipore 07818) expres...

Nature Reviews Clinical Oncology, Published online: 23 September 2019; doi:10.1038/s41571-019-0268-3HER2-targeted therapies have dramatically improved the outcomes in women with HER2-positive breast cancer. Furthermore, genetic sequencing studies have revealed HER2 alterations in a range of other cancers, including gastric cancer, colorectal cancer and non-small-cell lung cancer. In this Review the authors describe the available data on HER2-targeted therapies beyond breast cancer.

We report a 76-year-old patient who was diagnosed with concurrent accessory breast and primary lung cancer, both were positive for somatic BRCA-2 (E1593D) mutation. He received concurrent radiation and platinum-based chemotherapy for lung cancer with good response, but breast cancer progressed in about 8 months, and further progressed after single agent anastrozole in 10 months. Next Generation Sequencing (NGS) of breast cancer was also positive forCCND1 (Cyclin D1) and FGFR1 amplifications. Despite a poor molecular profile of breast cancer, and progression following platinum-based chemotherapy and anastrozole, he was succ...

Conclusion MTDH is pro-oncogenic factor playing multifaceted and diverse roles in cancer progression. Its association and central role in regulating signaling pathways such a MAPK, wnt/β-catenin, PI3K/AkT, NF-κβ pathways in various cancers shows that it plays a vital role in metastasis. MTDH contribution to chemo and radiotherapy resistance provides a new direction for the development of anticancer therapeutics. Multiple mechanisms converge to promote expression of MTDH in cancers. Further studies are therefore warranted to determine whether the elevated MTDH expression has prognostic value for development...

Conclusions: The newly developed radiomic signature was a powerful predictor of LN metastasis and the radiomics nomogram could facilitate the preoperative individualized prediction of LN status. Introduction Gastric cancer (GC) is one of the most common malignant tumors and the second leading cause of cancer-related deaths worldwide (1). Accurate evaluation of lymph node metastasis (LNM) status in GC patients is vital for prognosis and treatment decisions (2–4). Some histopathologic factors and biomarkers (e.g., lymphatic invasion, matrix metalloproteinase-2) are found to be able to predict LNM in GC, but mos...

Li Liu, Jiajing Lin and Hongying He* Department of Obstetrics and Gynecology, Liuzhou Worker’s Hospital, Fourth Affiliated Hospital of Guangxi Medical University, Liuzhou, China Background and Objective: Endometrial cancer (EC) is a common gynecological malignancy worldwide. Despite advances in the development of strategies for treating EC, prognosis of the disease remains unsatisfactory, especially for advanced EC. The aim of this study was to identify novel genes that can be used as potential biomarkers for identifying the prognosis of EC and to construct a novel risk stratification using these genes. Me...

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...

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.

In this study, we evaluated whether the combination of focused ultrasound (FUS) and microbubbles can improve adoptively NK-92MI cell infiltration into ovarian tumors through biodistribution, immunofluorescence, and flow cytometry. The treatment effects of using this strategy twice a week were explored. The potential molecular mechanism of FUS assisting NK cell therapy was also initially explored through evaluating the expression of ICAM1 and CX3CL1 by qRT-PCR. Our results indicated that FUS and microbubbles can improve NK-92MI cells’ infiltration into tumors, and the combination of FUS and NK-92MI cells had a better ...
