In a previous genome-wide gene expression profiling analysis using an invasion cancer cell lines model, we have identified Slug as selectively overexpressed in the highly invasive cancer cells. Here, we investigated the clinical significance of Slug in lung adenocarcinoma and the role of Slug in the process of cancer cell invasion and metastasis. ⋯ Slug expression can predict the clinical outcome of lung adenocarcinoma patients. Slug is a novel invasion-promoting gene in lung adenocarcinoma.

This study examined a pretarget radioimmunotherapy strategy for treatment of an i.p. tumor model (LS174T). ⋯ Pretarget radioimmunotherapy using regional administration of CC49 fusion protein and i.p. (90)Y- or (177)Lu-DOTA-biotin represents a successful therapeutic strategy in the LS174T i.p. tumor model and this strategy may be applicable to human trials in patients with i.p. ovarian cancer.

Recent studies have detected aberrant promoter methylation of adenomatous polyposis coli promoter 1 A (APC), cyclin-dependent kinase inhibitor-2A (p16(INK4a)), retinoic acid receptor beta2, and RAS association domain family protein 1 (RASSF1A) in bronchial aspirates and suggested their use as biomarkers for lung cancer diagnostics. The purpose of this study was to validate these candidate marker genes in a retrospective cohort study. ⋯ Our findings suggest that the QMSP assay could be applied as a reflex test in cases of suspected lung cancer that defy a definite diagnosis by conventional methods. Thus, the assay could be a useful diagnostic adjunct especially regarding peripheral tumors.

To determine the maximum tolerated dose (MTD), dose-limiting toxicity (DLT), and pharmacokinetics of tasidotin (ILX651), a dolastatin-15 analogue, when administered on days 1, 3, and 5 every 3 weeks in patients with advanced solid tumors. ⋯ The recommended dose for phase II studies and the MTD when tasidotin is administered on days 1, 3, and 5 every 3 weeks is 34.4 mg/m(2). The favorable toxicity profile of tasidotin compared with other antitubulin agents, including other dolastatin analogues, and its novel mechanism of action support further disease-directed evaluation of this agent.

To determine the maximum tolerated dose, dose-limiting toxicity, and pharmacokinetics of the dolastatin-15 analogue, tasidotin (ILX651), when administered i.v. daily for 5 days every 3 weeks. ⋯ The maximum tolerated dose and recommended phase II dose for tasidotin when administered on this schedule was 27.3 mg/m(2)/d. The favorable toxicity profile of tasidotin compared with other antitubulin agents (particularly the lack of severe cumulative neuropathy, peripheral edema, and fatigue), the observed antitumor activity of tasidotin, and its novel mechanism of action support further disease-directed evaluations of this agent on this 5-day schedule every 3 weeks.
