Prior to surgery, consented subjects will ingest a capsule containing \[14C\]PhIP. This amount of \[14C\]PhIP (84 micrograms PhIP; 15.6 micro-curies) is equivalent to that in 2 very well done grilled/barbecued chicken breasts (Sinha 1995); the amount of radioactivity is equivalent to the dose received in a commercial airline flying at 30,000 ft. for 5 h (HPS 2007) or to the amount received during a typical chest x-ray.

We propose to recruit subjects scheduled for pancreatectomy as a treatment for pancreatic cancer. These subjects will ingest a very low dose of radiolabeled PhIP, a meat-derived carcinogen, and a small amount of resected tissue (waste) will be analyzed with highly sensitive technology to determine if this carcinogen binds to DNA in the pancreas.

Pancreatic cancer is rapidly fatal in most cases and little is known about its causes. Identifying and modifying risk factors can reduce mortality through prevention. Carcinogens that form in meat cooked at high temperatures may be modifiable risk factors for pancreatic cancer, but direct evidence is needed to demonstrate involvement in pancreas tissue. We propose to recruit subjects scheduled for pancreatectomy as a treatment for pancreatic cancer. These subjects will ingest a very low dose of radiolabeled PhIP, a meat-derived carcinogen, and a small amount of resected tissue (waste) will be analyzed with highly sensitive technology to determine if this carcinogen binds to DNA in the pancreas. We hypothesize that the meat-derived carcinogen will bind to DNA in the pancreas. The amount of PhIP ingested is equivalent to the amount in two very well-done barbecued chicken breasts and the dose of radioactivity is comparable to a typical chest x-ray. This research can increase understanding of pancreatic carcinogenesis, facilitating the design of prevention strategies.
