thermal signature of patients undergoing radiation therapy

Conditions: Lung Cancer

Summary: the goal of this clinical research study is to evaluate whether thermal imaging (recording body temperature) can be used to check the body's response to cancer therapy. primary objective: * the primary objective of this study is to establish techniques and methodologies of quantifying thermal signatures and their changes for cancer patients undergoing chemoradiation therapy. secondary objective: * the secondary objective is to evaluate correspondence between changes of thermal signature of a normal organ, e.g. lung or esophagus, versus the toxicity of that organ from chemoradiation therapy.

for patients: thermal imager: a thermal imager (a camera similar to a digital camera) takes pictures of skin surfaces. the imager is able to view temperature distribution of the skin surface. study participation: if you agree to take part in this study, your body temperature will be measured with thermal imaging. you will have thermal imaging sessions several times before the cancer treatment starts and during the therapy course. you will be given detailed instructions on how to prepare for the imaging sessions ahead of time as well as what to expect during the imaging sessions. before beginning thermal imaging, your temperature will be measured with a thermometer. to perform thermal imaging, you will be asked to take off all of your clothes in a private room and stand still in front of a thermal imaging camera. no one will be present while you disrobe. when you have finished taking off your clothes a radiation oncologist or other medical doctor will record several pictures from a computer stationed outside the room. pictures of your front, back, and side views will be taken. these pictures will look like a silhouette (body outline) with thermal coloring. the entire imaging session should take about 10 minutes to complete each time. length of study: your participation will be over in this study after the thermal images have been recorded. this is an investigational study. thermal imaging is fda approved and commercially available for breast cancer screening. its use in this study is investigational. up to 35 patients will take part in this study. all will be enrolled at m. d. anderson. for volunteers: thermal imager: a thermal imager (a camera similar to a digital camera) takes pictures of skin surfaces. the imager is able to view temperature distribution of the skin surface. study participation: if you agree to take part in this study, your body temperature will be measured with thermal imaging. you will have thermal imaging sessions several times during the course of this study. you will be given detailed instructions on how to prepare for the imaging sessions ahead of time as well as what to expect during the imaging sessions. before beginning thermal imaging, your temperature will be measured with a thermometer. to perform thermal imaging, you will be asked to take off all of your clothes in a private room and stand still in front of a thermal imaging camera. no one will be present while you disrobe. when you have finished taking off your clothes a radiation oncologist or other medical doctor will record several pictures from a computer stationed outside the room. pictures of your front, back, and side views will be taken. these pictures will look like a silhouette (body outline) with thermal coloring. the entire imaging session should take about 10 minutes to complete each time. volunteers will not participate in any part of cancer treatment, diagnostic imaging tests (ct, pet, etc), or any other clinical procedures in md anderson. volunteers will not need to see physicians at md anderson or elsewhere. thermal images will be taken 4 times during one day for a volunteer (morning, midmorning, earlier afternoon, late afternoon). volunteers should not take any medications or perform any other medical procedures from morning to late afternoon until the thermal imaging is completed. length of study: your participation will be over in this study after the thermal images have been recorded. this is an investigational study. thermal imaging is fda approved and commercially available for breast cancer screening. its use in this study is investigational. up to 10 volunteers without cancer (5 males and 5 non-pregnant females) will take part in this study. all will be enrolled at m. d. anderson.
