Active clinical trials for "Lung Neoplasms"

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. It is not yet known which combination chemotherapy regimen is most effective in treating non-small cell lung cancer. PURPOSE: This randomized phase II trial is comparing different combination chemotherapy regimens to see how well they work as first-line therapy in treating patients with stage IIIB or stage IV non-small cell lung cancer that cannot be removed by surgery.

RATIONALE: Drugs used in chemotherapy, such as irinotecan, cisplatin, and etoposide work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to damage tumor cells. Giving combination chemotherapy together with radiation therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving combination chemotherapy together with radiation therapy works in treating patients with stage III non-small cell lung cancer that cannot be removed by surgery.

Pemetrexed was known to be effective to pulmonary adenocarcinoma and gefitinib was known to be more effective to non-small cell lung cancer (NSCLC) patients with clinical characteristics such as adenocarcinoma, never smoker and female. The investigators try to evaluate which drug (pemetrexed vs gefitinib) is more efficious to NSCLC patients with clinical characteristics such as adenocarcinoma and never smoking history as second- or further-line therapy.

Although the efficacy of topotecan as second-line chemotherapy for SCLC has been consistently demonstrated in phase II/III clinical trials, the choice of irinotecan as first-line therapy prevented use of the evidence-based option. This pilot study will be conducted to determine the activity and safety of topotecan in SCLC patients refractory to first-line therapy with irinotecan and platinum.

This study was designed to determine whether adjuvant vinorelbine plus cisplatin and endostar prolongs overall survival compare to vinorelbine plus cisplatin alone among patients with completely resected IB-IIIA non-small-cell lung cancer. The patients with completely resected stage IB to stage IIIA non-small cell lung cancer were randomly assigned to the group of vinorelbine plus cisplatin plus endostar or to the group of vinorelbine plus cisplatin . The primary end point was overall survival; principal secondary end points were recurrence-free survival and the toxicity and safety of the regimens.

A phase II, multicenter, randomized trial of 3D Radiotherapy versus 3D Radiotherapy and erlotinib (Tarceva®) in patients with localized-unresectable (IA-IIIB) non-small cell lung cancer non susceptible for chemotherapy treatment, to compare safety and toxicity profile, and the progression-free survival in both arms of treatment (3D Radiotherapy versus 3D Radiotherapy + erlotinib) in patients who have not received previous chemotherapy.

To examine the feasibility of VATS lobectomy for clinical stage IB or II non-small cell lung cancer. Success is defined as VATS lobectomy without conversion. If success rate over 90%, VATS lobectomy is considered as feasible procedures for clinical stage IB or II non-small cell lung cancer

Optical coherence tomography will be a feasible adjunct to flexible bronchoscopy, and provide images with good sensitivity and specificity to determine the presence of endobronchial malignancies.

Nitroglycerin will increase the effectiveness of treatment with induction chemotherapy and concurrent chemo-radiotherapy by reducing chemo-radio resistance through an increased oxygen pressure in tumoral tissue. The combination treatment of nitroglycerin and chemotherapy will result in longer disease-free and over-all survival in patients with locally advanced NSCLC

RATIONALE: Collecting and storing samples of blood and exhaled breath from patients with cancer and from healthy participants to study in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is collecting and analyzing samples of blood and exhaled breath from patients who have or are at high risk for lung cancer and from healthy participants.
