Active clinical trials for "Carcinoma, Non-Small-Cell Lung"

The purpose of this study is to examine the feasibility of assisted-VATS (video-assisted thoracoscopic surgery) sleeve lobectomy for non-small cell lung cancer for non-small cell lung cancer. Success is defined as assisted-VATS sleeve lobectomy without conversion. If success rate over 90%, assisted-VATS sleeve lobectomy is considered as feasible procedures for non-small cell lung cancer.

Radiation therapy is an important part of the treatment for lung cancer when treatment intent is for cure. Radiation is a local modality of treatment, that is, it only treats the area that the radiation can target. Therefore it is critical to be able to visualize all the areas of tumor involvement. With current imaging tests such as computed tomography scans (CT), the scans may not be sensitive enough to detect all areas of cancer involvement but with newer imaging tests, such as positron emission tomography (PET), the investigators may be able to better target all the tumor that the CT scan may miss. There are two clinical trials being conducted by the Ontario Clinical Oncology Group (OCOG)looking at PET in lung cancer. This proposal is a companion study to the OCOG PET lung trials. In brief, this study will evaluate the ability of CT alone versus combined PET CT imaging to determine the size of the tumor (or gross tumor volume) along with the tiny extensions of cancer cells (or microscopic extension). The gross tumor volume and its extension as determined by CT or PET CT will then be compared to measurements made on the surgically removed tumor. Treatment with radiation therapy must include all the gross tumor and its extension in order to be successful for cure. If the radiation treatment does not treat all the identified tumor then the chance for cure is lost. There have only been two previous reports of the ability of CT to determine the gross tumor volume and its extension. There are no similar reports using PET CT. This study will be the first of its kind to evaluate how accurate PET CT can be in detecting the gross tumor and its microscopic extension using the surgically removed tumor measurements as the gold standard. If PET CT is able to more accurately determine the tumor volume including its microscopic extension, then this will help oncologists to better treat lung cancer using more accurate radiation treatment volumes.

Recently a radomized trial of vinorelbine versus best supportive care in patients at 70 years of age or older demonstrated a definite improvement in overall survival rate and quality of life with chemotherapy. The role of combination therapy containing the platinum compound, which is the standard therapy for the young patients is still vague. Gemcitabine and carboplatin have favorable toxicity profile.

The purpose of this study is to evaluate local disease control after 2 years in patients with non-metastatic, non-operated non-small-cell lung cancer treated by radiotherapy. Eligible patients will be recruited and registered consecutively (no randomization). The estimated inclusion period is approximately 24 months. The duration of the research is 4 years. The number of patients required in this multicentric prospective study is 120: 20 patients in the SBRT-1 arm (cyberknife), 80 patients in the SBRT-2 arm (linear accelerator-based) 20 patients in the conformational radiotherapy arm. This is a prospective, multicentric, non comparative and non randomized study.

The primary aim of the study is to identify a predictive molecular signature for response to chemotherapy, according to WHO criteria, in patients with non-small cell lung cancer by studying the transcriptome (miRNAs and mRNAs) and the single nucleotide polymorphism (SNPs) by using high throughput techniques.

The primary objective of this study is to assess the activity of subcutaneous (SC) amifostine on the incidence and severity of acute radiochemotherapy-induced esophagitis in patients with unresectable Stage IIIA or IIIB non-small cell lung cancer (NSCLC) receiving combined modality therapy.

Hypothesis is that surgery is of benefit in locally advanced NSCLC with N2 disease. Patients are randomised to surgery or not.

Locally advanced non-small cell lung cancer, NSCLC, (Stage III) is potentially curable with aggressive combined modality therapy (chemotherapy and radiation). Conventional imaging can only evaluate gross anatomic abnormalities but functional imaging with positron emission tomography (PET) may more accurately identify patients who will benefit from aggressive combined modality therapy. This prospective randomized clinical trial will enroll 400 patients that have undergone conventional staging for lung cancer and have been found to have Stage III NSCLC. The patients will then be randomized to either standard combined modality therapy for Stage III NSCLC or to PET imaging prior to combined modality therapy with curative intent. Based on the PET findings, patients will either be suitable for combined modality therapy with curative intent or not.

This Observational study will explore the utility of the Biodesix, Inc. "PIR" (primary immune response) test to predict outcomes in treatment-naïve advanced stage NSCLC with PD-L1 tumor proportion score (TPS) > 50% and ECOG performance status (PS) 0-2 NSCLC patients who are treated with PD-1/PD-L1 based therapy with or without the addition of platinum based chemotherapy.

It has not been established whether platinum-based doublets is better than single agent chemotherapy in EGFR mutant NSCLC patients who failed first-line EGFR TKI. In this prospective trial, the investigators try to evaluate whether the progression-free survival of pemetrexed/cisplatin (PC) regimen is longer than that of pemetrexed single(P) regimen in NSCLC patients who have progressed after first line treatment of EGFR-TKI.
