Blue and Amber Light Exposure in Patients With Rectal and Pancreatic Cancer
The Effect of Peri-surgery Blue and Amber Light Exposure in Subjects Undergoing Medical and Surgical Treatment of Cancer
This study will evaluate light therapy used in combination with standard therapies for pancreatic and rectal cancer. Participants will receive chemotherapy, radiation, and surgical treatments identical to that they had not been involved in the study. The only alteration is that some participants will be exposed additionally to either blue or amber light using commercially available seasonal affective disorder (SAD) lights that are approved for human use. Participants will use the SAD light in their own homes throughout the course of their radiation and chemotherapy treatments. They will wear goggles that filter with the desired color of light. As a comparison, another group of participants will be exposed only to their usual lighting conditions. The assignment to blue light, amber light, or usual light groups will be random.
In addition to the light exposure, participants will be asked to have 10 mL of blood drawn for research purposes at 4 time points. This blood will be analyzed for markers of inflammation and circadian clock activation. Participants also will be asked to complete surveys at 3 time points. These surveys will evaluate for effects changs in sleep, pain, and quality of life. Finally, participants will be asked to wear a small clip-on light sensor and a heart rate variability monitor for 7 days. These monitors will provide information on the level of light exposure and the participant's physiologic response to the light. For participants going on to surgery, we will obtain a small sample of the resected pancreas or rectal tumor for research analysis. The investigators will obtain this sample only after the necessarily analysis has been performed for their clinical care.

Detailed Description
The investigators incorporate appropriate control participants, which include participants who are matched for stage and age and who undergo neoadjuvant chemoradiation and/or surgery but who are not exposed to modulation of their environmental light.
There are no deviations from the standard of care for these patients. They will be receiving care identical to that had they not been involved in this study. The only alteration is that some participants will be exposed additionally to either blue or amber light. The investigators use commercially available seasonal affective disorder (SAD) lights that are already approved for therapeutic human use. These lights are small and portable and approved for use for seasonal affective disorder (SAD). The investigators have used them in other human trials and have not identified any adverse or unexpected events.
The participants will be asked to have 10 mL of blood drawn for research purposes at 4 time points to assess for markers of the inflammatory response and circadian clock activation. Additionally, they will be asked to complete surveys at 3 time points to assess for quality-of-life measures. They will be asked to wear a small light sensor and a heart rate variability monitor for 7 days to measure the adequacy of light exposure and physiologic response to the exposure, respectively.
In the participants who undergo definitive operative resection (e.g., Whipple (pancreaticoduodenectomy) procedure, mesorectal proctectomy), we will analyze a sample of the resected specimen. The investigators will obtain this sample only after complete pathological examination and reporting in accordance with best practices of care. Thus, the sample being acquired for research purposes is discarded biological tissue and no additional sampling is performed. In fact, there are absolutely no deviations or interference with the processes of delivering care.
