Dynamic changes of phenotypically different circulating tumor cells sub-populations in patients with recurrent/refractory small cell lung cancer treated with pazopanib.

The aim of the study was to investigate the effect of 2-line pazopanib on the different CTCs subpopulations in SCLC patients and evaluate the clinical relevance of their changes. Different CTCs subpopulations were evaluated before pazopanib initiation (n = 56 patients), after one-cycle (n = 35) and on disease progression (n = 45) by CellSearch and double immunofluorescence using anti-CKs and anti-Ki67, anti-M30 or anti-Vimentin antibodies. Before treatment, CTCs were detected in 50% of patients by CellSearch whereas 53.

TTF-1- and/or CD56-positive Circulating Tumor Cells in patients with small cell lung cancer (SCLC).

The aim of the study was to evaluate the phenotypic CTCs heterogeneity (TTF-1 and/or CD56) in SCLC patients and correlate it with the CellSearch. Peripheral blood was obtained from 108 consecutive patients. CTCs were detected by CellSearch and double-immunofluorescence using anti-CD45, anti-TTF-1 and anti-CD56 antibodies.

Sequential administration of vinorelbine plus cisplatin and bevacizumab followed by docetaxel plus gemcitabine and bevacizumab compared to docetaxel plus cisplatin and bevacizumab regimen as first-line therapy for advanced or metastatic non-squamous non-small cell lung cancer: A multicenter randomized phase II trial of the Hellenic Oncology Research Group (HORG).

Objectives: To compare the activity and tolerance of the consecutive administration of four active chemotherapeutic agents in combination with bevacizumab to a bevacizumab- and platinum-based chemotherapy doublet as front-line treatment in patients with non-squamous NSCLC.

Patients And Methods: Patients with advanced/metastatic NSCLC, performance status of 0-2 and normal organ function were randomized to receive either 3 cycles every 3 weeks of cisplatin 80 mg/m(2) (day 1), oral vinorelbine 60 mg/m(2) (days 1 and 8) and bevacizumab 15 mg/kg (day 1) every 3 weeks (VCB regimen) followed by 3 cycles of docetaxel (75 mg/m(2), day 1), gemcitabine (1100 mg/m(2), days 1 and 8) and bevacizumab 15 mg/kg (day 1) (DGB regimen) (arm A) or 6 cycles of cisplatin 80 mg/m(2), docetaxel 75 mg/m(2) and bevacizumab 15 mg/kg on day 1 (DCB regimen; arm B) every 3 weeks.

Results: Thirty-eight and 39 patients were enrolled in arm A and B, respectively.

A phase I clinical trial of weekly oral topotecan for relapsed small cell lung cancer.

Purpose: To determine the dose-limiting toxicities (DLTs) and the maximum tolerated dose (MTD) of oral topotecan administered weekly in patients with relapsed small cell lung cancer (SCLC).

Patients And Methods: Patients were treated with oral topotecan on days 1, 8, and 15, every 28 days. The dose was escalated by 0.

Postoperative treatment with docetaxel, cisplatin, and capecitabine (DCX) and chemoradiotherapy (CRT) with capecitabine for resected gastric adenocarcinoma.

Introduction: We conducted a feasibility study on docetaxel/capecitabine/cisplatin (DCX) with chemoradiotherapy as adjuvant treatment for gastric cancer patients.

Methods: Patients were scheduled to receive 2 cycles of DCX, followed by 50.4 Gy plus capecitabine as radiotherapy, followed by an additional 2-DCX cycles.
