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...

Authors: Rouviere D, Veillon R, Chaltiel L, Simonneau Y, Filleron T, Milia J, Guibert N, Melloni B, Raherisson C, Didier A, Mazieres J Abstract The central nervous system (CNS), through carcinomatous meningitis or solid brain metastases, is the most common site of recurrence in non-small cell lung cancers (NSCLC) with activating mutations. Our retrospective study describes the population of patients with CNS metastases of NSCLC harboring activating mutation with targeted therapy (EGFR, ALK, BRAF, HER2) in 4 French regional reference hospitals. 60 patients were analyzed. The proposed treatments were heterogeneous an...

In conclusion, thalidomide and gefitinib exhibit synergistic effects on both TKI-sensitive and -resistant NSCLC cells by targeting the EGFR signaling pathways, suggesting that the combination strategy is promising for the treatment of NSCLC. PMID: 31132355 [PubMed - as supplied by publisher]

Conclusions: The ZHER2:V2-pemetrexed conjugates showed promising targeted antitumor activity against HER2-positive lung adenocarcinoma with reduced side effects compared with pemetrexed. ZHER2:V2-pemetrexed is a novel molecular probe with great clinical potential for diagnosis and treatment. Keywords: HER2, affibody, 99mTc-ZHER2:V2-pemetrexed, molecular imaging, therapeutic response. This study was supported by the funds (NO. 81571702) from the National Natural Science Foundation of China project.

CONCLUSIONS: This prospective large-scale cohort study is the first to show comprehensively the frequency and clinical demographic characteristics of those with HER2-positive advanced lung tumors in detail, providing critical historical data for future drug development against HER2-positive NSCLC. Future treatment strategies would be developed stratified according to the types of HER2 aberrations.

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...

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...
