Active clinical trials for "Lung Neoplasms"

RATIONALE: Measuring levels of transforming growth factor-beta (TGF-beta) in the blood of patients with epithelial cancers (head and neck, lung, breast, colorectal, and prostate) may help doctors predict how patients will respond to treatment with radiation therapy. PURPOSE: This research study is measuring levels of TGF-beta in patients with epithelial cancers who are undergoing radiation therapy.

RATIONALE: Studying samples of blood from patients with cancer 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 looking at blood samples from patients with non-small cell lung cancer and from healthy volunteers.

RATIONALE: Studying samples of tissue, blood, sputum, and urine from patients with lung cancer and from healthy participants 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 looking at biomarkers for lung cancer using tissue samples from patients with lung cancer and from healthy participants.

This research studies collecting and storing tissue and blood samples from patients with lung cancer who are undergoing surgery. Collecting and storing samples of tissue and blood from patients with lung cancer to study in the laboratory may help doctors learn more about changes that may occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer.

RATIONALE: Studying samples of blood and tumor tissue in the laboratory from patients with cancer and blood from healthy participants may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. PURPOSE: This laboratory study is looking at cancer-related protein biomarkers in the blood and tumor tissue of patients with cancer and in the blood of healthy participants.

RATIONALE: Studying samples of blood and tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at blood and tissue samples from patients with locally advanced, metastatic, or recurrent non-small cell lung cancer treated with bevacizumab, carboplatin, and paclitaxel.

RATIONALE: Chemotherapy may cause blood clots to form in the thigh, leg, and lung. This study may help doctors understand how often blood clots occur in patients undergoing chemotherapy. PURPOSE: This clinical trial is studying how often blood clots occur in patients undergoing chemotherapy for solid tumors, including colorectal cancer, stomach cancer, lung cancer, ovarian cancer, pancreatic cancer, prostate cancer, or metastatic breast cancer

RATIONALE: Gathering information about how often problems with neurocognitive functioning occur in patients with newly diagnosed upper aerodigestive tract cancers may help doctors learn more about the disease. PURPOSE: This clinical trial is studying neurocognitive functioning in patients with newly diagnosed upper aerodigestive tract cancers receiving treatment at Henry-Joyce Cancer Clinic.

Primary Objectives: To collect accurate and reliable respiration-induced anatomic structure motion data using four-dimensional (4-D) imaging technology. To analyze these data to study respiration-induced variations and patterns in variations of positions, shapes and volumes of tumors and normal anatomic structures in the thorax and abdomen over a breathing cycle, from one breathing cycle to the next, day-to-day and over the course of radiotherapy. To assess dosimetric and potential clinical consequences of respiratory motion in the current practice of radiotherapy through preclinical treatment simulation (treatment planning) studies. To quantify the potential consequences of explicitly accounting for respiration-induced motion on dose distributions and outcome (tumor control probabilities and normal tissue complication probabilities) through preclinical treatment simulation studies. Secondary Objectives: To investigate the feasibility of using patient training to regulate patient breathing and improve the quality of images and to stratify patients for their eligibility for respiratory-correlated imaging and radiotherapy and for the implementation of various strategies for mitigation of respiratory-induced motion. To assess the degree of correlation of the marker (or internal anatomic structure such as diaphragm) being tracked as surrogate of breathing with the motion of structures and the intra-fraction and inter-fraction reproducibility of such correlation. To quantify the effects of radiation therapy on the patterns of respiratory-induced motion of structures through preclinical treatment simulation studies. To compare various strategies for either accounting for or mitigating respiration-induced motion in the planning and delivery of radiation therapy.

RATIONALE: Measuring changes in glucose metabolism in patients with cancer may help doctors predict how patients respond to treatment. PURPOSE: This clinical trial is studying glucose metabolism in patients with non-small cell lung cancer treated with targeted therapy and chemotherapy.
