Filter by:This partially randomized phase I/II trial studies the side effects and best dose of image-guided, intensity-modulated photon or proton beam radiation therapy and to see how well they work in treating patients with stage II-IIIB non-small cell lung cancer. This trial is testing a new way of delivering radiation dose when only the tumor receives dose escalation while the surrounding normal structure is kept at standard level. Photon beam radiation therapy is a type of radiation therapy that uses x-rays or gamma rays that come from a special machine called a linear accelerator (linac). The radiation dose is delivered at the surface of the body and goes into the tumor and through the body. Proton beam radiation therapy is a type of radiation therapy that uses streams of protons (tiny particles with a positive charge) to kill tumor cells. Both methods are designed to give a higher than standard dose of treatment to the tumor and may reduce the amount of radiation damage to healthy tissue near a tumor.
Cancer patients are highly variable in their body composition, specifically in the proportion of fat and muscle. Some patients tend to gain fat and lose muscle (or lean body mass) at the same time. These patients can develop severe muscle wasting, termed sarcopenia. Patients with sarcopenia have more severe treatment related toxicity requiring delays, dose reductions and stopping of treatment, and have reduced survival. One potential explanation for this is that patients with sarcopenia have a reduced volume of lean body mass into which chemotherapy drugs are distributed, resulting in a higher concentration and greater toxicity. This study will randomize lung cancer patients to either the standard dosing strategy based on body surface area or experimental, personalized dosing based on lean body mass. Based on retrospective findings in this patient population, the investigators expect to find that severe toxicity will be reduced for sarcopenic patients on the personalized dosing arm based on lean body mass.
Advanced non-small-cell lung cancer (NSCLC) patients without epidermal growth factor receptor (EGFR) mutations show a poor prognosis. Gemcitabine combined with cisplatin chemotherapy is an effective treatment measures for EGFR mutation-negative NSCLC patients, but the prognosis remains poor. Chemotherapy combined with targeted monoclonal antibody treatment may be better treatment options in these patients. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Bevacizumab blocks the ability of tumors to grow new blood vessels and spread. It is not yet known whether cisplatin and gemcitabine is more effective when given alone or with bevacizumab. This randomized trial studies how well giving cisplatin and gemcitabine alone or in combination with Bevacizumab (Avastin) works in treating patients with stage IIIB/IV non-squamous NSCLC without EGFR mutations.
Modern anti-cancer treatments are focused on development of molecular based therapies i.e. specific treatments targeted against underlying biological processes. There is still much to learn about the biology of cancer, especially in tumours such as colorectal and lung cancer where it is likely multiple heterogenous signaling pathways are responsible for progression of disease. This project aims to evaluate circulating tumour cells (CTCs) as a surrogate biomarker for tumour characteristics and to determine how they may used to identify new targets for therapeutic agents. Their use could be applied to diagnosis of cancer, prediction of response to therapies and prognosis, ultimately across a broad range of tumour types. Currently the only way to investigate molecular features of a cancer is through procurement of an invasive tumour biopsy that is often difficult to obtain, often results in insufficient material and is unpleasant for the patient. A blood-based test would provide a much more practical and patient friendly alternative. The enumeration and molecular characterisation of CTCs has the novel potential of being a "virtual biopsy" of the tumour and offers the opportunity for immediate therapeutic decisions (eg. if the tumour develops a therapy resistant genotype while on treatment). CTCs have been known to circulate in bloodstream of cancer patients for many years and are known to lead to cancer metastases. They have been very difficult to detect, up until recently, due to the complexity of the metastatic process and detecting relatively small numbers of CTCs amongst billions of red and white blood cells. However, technology has moved on dramatically in the last few years. The FDA approved CellSearch platform (Veridex, NJ) can isolate and enumerate CTCs based on the immunomagnetic capture of EpCAM (epithelial cell adhesion molecule) positive cells. Several studies have recently demonstrated the value of CTC enumeration in reflecting prognosis and predicting early response to systemic chemotherapy. For example, in a study comprising 456 patients with metastatic colorectal cancer starting a new line of therapy, patients with =3 CTCs per 7.5 ml blood at baseline had shorter progression free survival (PFS) and overall survival (OS) compared to those patients with < 3CTCs at baseline (PFS 4.5 versus 7.9 months P=0.0001; OS 8.5 versus 19.1 months P=0.0000 respectively). Overall survival for patients converting to or maintaining CTCs =3 within a few weeks of commencing systemic therapy remained worse than for those patients maintaining CTC counts < 3 per 7.5ml blood. Similar results have been reported in patients with breast and hormone refractory prostate cancer (HRPC). These studies have led to FDA approval of the CellSearch system as an adjunct to monitoring patients with these 3 tumour types. The CellSearch platform, however, does not allow for the downstream DNA analysis of captured cells and the ferroparticle-coated CTCs are non-viable. Furthermore, this platform is a multi-machine, multi-kit system that is laborious (typical 3-7 days turnover time), expensive (USD 650), and subject to operator variance. In this protocol, the investigators propose for the first time, an automated, fully quantitative system for isolation and enrichment of CTCs. The key differentiating feature of our novel CMOS system is the electrochemical identification and counting of tumour cells using a high density electrode array with associated electronics for addressing the electrodes. This leads to a standardized assay for tumour cells with a shorter turnover time and without the need of a skilled operator. This system also holds the potential for allowing the molecular characterization of CTCs. This study aims to enumerate CTCs using a novel CMOS technology in patients with metastatic cancer who are scheduled to receive palliative chemotherapy, and to correlate CTC number with clinical outcome. In Part I of the study, the investigators will recruit 10 patients with metastatic NSCLC and 10 patients with metastatic CRC in order to assess the feasibility of CTC enumeration in patients. In particular, the investigators aim to establish whether CTCs are detectable using the novel CMOS technology in patients with metastatic cancer. In Part II of the study, the investigators will recruit 21 patients with metastatic NSCLC and 89 patients with metastatic CRC in order to compare CTC counts as determined by the CMOS technology with CTC counts as determined by the CellSearch platform. Blood samples will be collected at a single time point prior to the start of palliative chemotherapy. CTC numbers will be correlated with clinical outcome in all evaluable patients. The investigators hypothesize that CTC enumeration by a novel CMOS technology is non-inferior to CTC enumeration by the CellSearch platform in patients with advanced solid malignancies.
The number of NSCLC patients above 70 years of age who are non-squamous histology is increasing around the world. Although previous guidelines often recommend single agent therapy for NSCLC, recent studies suggest that platinum doublets may be better than standard monotherapy in elderly. We hypothesize that for elder patients (≥70 years of age) with non-squamous NSCLC, pemetrexed and carboplatin is more effective than pemetrexed monotherapy in terms disease progression, overall survival, and quality of life and tolerability.
Neutropenia is one of the most frequent adverse effects of chemotherapy, and the main factor to limit the dosage and the continuation of chemotherapy. A newly pegylated rhG-CSF was independently developed by JIANGSU HENGRUI Medicine Co., Ltd, China. Phase 1a, 1b and phase 2 trials have shown that pegylated rhG-CSF has decreased renal clearance, increased plasma half-life, and prolonged efficacy in compare with filgrastim. The purpose of this study is to determine the safety and effectiveness of pegylated rhG-CSF in preventing neutropenia following chemotherapy in patients with advanced NSCLC.
A phase II, multicenter, randomized, double-blind, placebo-controlled study was carried out. Patients were randomly assigned to the treatment (PC + pegylated endostatin) or the control group (PC+ placebo). The efficacy was evaluated every six weeks.Follow-up continued until disease progression or death.
When considering 1st line gefitinib treatment for NSCLC, the investigators need epidermal growth factor receptor (EGFR) mutational status of the tumor. But most patients do not give us such information at the time of diagnosis, because it requires tumor tissue and some time period for EGFR examination. So, investigators develop a protocol of 1st line gefitinib treatment for NSCLC according to FDG-PET response. If a patient shows 20% or more decrease of peak standard uptake value (SUV) after 1 week's gefitinib treatment, he or she will be continued the treatment. If a patient shows less than 20% decrease of SUV, he or she will be switched to other chemotherapy.
Concurrent chemoradiation (ChRT) is a standard care for unresectable stage III non-small cell lung cancer (NSCLC) patients with good performance status, and cisplatin/etoposide (EP) regimen is one of the most commonly used regimens. However, the prognosis of these patients is still rather poor. It has been demonstrated that Cyclooxygenase (COX)-2 plays an important role in the pathogenesis of lung cancer. Selective (COX)-2 inhibitors can promote chemosensitivity and radiosensitivity of tumor cells in preclinical trials. This is a single-institution, open-label, randomized phase II trial of celecoxib administered concurrently with cisplatin, etoposide, and radiation therapy in patients with locally advanced NSCLC, to determine the feasibility, activity, and toxicity of this combination on unresectable NSCLC, and further to examine biomarkers to predict response to the treatment.
Intercalated administration of Iressa® (gefitinib) on days 5-18 of chemotherapy cycle improve the efficacy of Pemetrexed/platinum regimen given as first-line treatment for never-smokers with advanced (stage IIIB/IV) lung adenocarcinoma.
