Published studies have not investigated the suitability of Response Evaluation Criteria in Solid Tumors (RECIST), European Association for the Study of the Liver (EASL) criteria, and modified RECIST (mRECIST) for assessing the response of patients with hepatocellular carcinoma to treatment with sorafenib combined with transarterial chemoembolization. Here, we aimed to define the earliest time at which the response to combination therapy could be accurately assessed and validate the prognostic value of these criteria at this early posttherapy time point. ⋯ The earliest time to evaluate the response to combination therapy is 3 months (median, 94 days) after therapy. EASL and mRECIST responses are independent predictors for OS at this early time point.

The transcription factor Forkhead box M1 (FOXM1) plays important roles in the formation of several human tumors, including pancreatic cancer. However, the molecular mechanisms by which FOXM1 promotes pancreatic tumor epithelial-to-mesenchymal transition (EMT) and metastasis are unknown. ⋯ Our findings demonstrated that FOXM1c contributes to pancreatic cancer development and progression by enhancing uPAR gene transcription, and thus, tumor EMT and metastasis.

The androgen receptor pathway remains active in men with prostate cancer whose disease has progressed following surgical or medical castration. Orteronel (TAK-700) is an investigational, oral, nonsteroidal, selective, reversible inhibitor of 17,20-lyase, a key enzyme in the production of androgenic hormones. ⋯ 17,20-Lyase inhibition by orteronel was tolerable and results in declines in PSA and testosterone, with evidence of radiographic responses.

We investigated the incidence of concomitant epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) rearrangements in Chinese patients with non-small cell lung cancer (NSCLC), and assessed responses to EGFR tyrosine kinase inhibitors (EGFR-TKIs) and crizotinib in such tumors. ⋯ ALK rearrangements and EGFR mutations could coexist in a small subgroup of NSCLC. Advanced pulmonary adenocarcinomas with such co-alterations could have diverse responses to EGFR-TKIs and crizotinib. Relative phospho-ALK and phospho-EGFR levels could predict the efficacy of EGFR-TKI and crizotinib.
