Prognostic significance of S100A16 subcellular localization in lung adenocarcinoma.

To discover novel tumor markers for lung adenocarcinoma (AC), we performed proteomics analysis and reported a correlation between S100A16 membranous expression in AC tissues and a poor prognosis. However, some patients with a good prognosis also showed S100A16 membranous staining. We re-evaluated immunohistochemically stained tissues, and found membrane-positive and nucleus-negative expressions to be significantly higher in the presence of the following: male, smoker, positive nodal metastasis, higher p-TNM stage, larger tumor, poorer differentiation, positive for lymphatic invasion, positive for vascular invasion, and positive for pleural invasion (all factors P < .

S100A16, a promising candidate as a prognostic marker for platinum-based adjuvant chemotherapy in resected lung adenocarcinoma.

Purpose: Although cisplatin-based adjuvant chemotherapy improves the survival of patients with resected non-small-cell lung cancer, not all patients show a survival benefit, and some patients experience severe toxicity. Therefore, identifying biomarkers is important for selecting subgroups of patients who may show improved survival with platinum-based adjuvant chemotherapy. S100A16 is thought to play key roles during different steps of tumor progression.

Thymic large cell neuroendocrine carcinomas (LCNECs) are rare, and the optimal regimen for second and subsequent lines of chemotherapy for the treatment of LCNECs remains unknown. In the present case study, a 59-year-old male with post-operative recurrent thymic LCNEC was treated with nab-paclitaxel and carboplatin every 4 weeks as third-line chemotherapy, and a partial response was achieved following 4 cycles of this regimen. The patient developed grade 4 neutropenia and grade 3 leukopenia, but none of the other toxicities, including peripheral neuropathy, were severe.

We conducted a multicenter phase II study of nedaplatin (NP) and irinotecan (CPT) for SCC of the lung. Fifty patients underwent 4 to 6 cycles of chemotherapy comprising of NP at 100 mg/m(2) on day 1 and CPT at 60 mg/m(2) on days 1 and 8 every 4 weeks.

Serum Anti-Gal-3 Autoantibody is a Predictive Marker of the Efficacy of Platinum-Based Chemotherapy against Pulmonary Adenocarcinoma.

Background: Identification of predictive markers for the efficacy of platinum-based chemotherapy is necessary to improve the quality of the life of cancer patients.

Materials And Methods: We detected proteins recognized by autoantibodies in pretreated sera from patients with lung adenocarcinoma (AC) evaluated as showing progressive disease (PD) or a partial response (PR) after cisplatin-based chemotherapy by proteomic analysis. Then, the levels of the candidate autoantibodies in the pretreated serum were validated by dot-blot analysis for 22 AC patients who received platinum-based chemotherapy, and the expression of identified proteins was immunohistochemically analyzed in 40 AC biopsy specimens.
