Title
Coffee, tea, caffeine and the risk of cancer
Summary
The association between coffee intake and various cancers have been studied over the last 35 years. In a Japanese cohort study, coffee intake was associated with a decrease in overall mortality, and inversely associated, though weakly, with overall cancer mortality among women. Recent studies have been suggestive of protective effects of coffee against head and neck cancer, esophageal SCC, breast cancer, endometrial cancer, kidney cancer, and glioma. On the other hand, some cancers are thought to have no association with coffee intake (esophageal adenocarcinoma, stomach cancer, lung cancer, ovarian cancer, prostate cancer, bladder cancer, testicular cancer and thyroid cancer). Tea intake may also be protective against ovarian and breast cancers. Considering that coffee and tea consumption is a highly prevalent lifestyle factor in the world, it is of interest to clarify the role of coffee and tea in cancer overall and in specific cancer sites. It will also be of interest to determine whether caffeine, a component of both coffee and tea intake, is associated with cancer. Examining coffee, tea and caffeine intake in a cohort study where the exposure measurements occurred before the cancer diagnosis occurred is an ideal approach since many of the previous studies were case-control in design with the issue of recall bias. Thus we propose to examine the role of coffee, tea and caffeine intake for cancer in the PLCO study.
Aims

Specific aim 1: To examine whether coffee intake is associated with the risk of cancer overall, and with the risk of specific cancer sites. Hypothesis 1: Coffee intake is protective against the risk of cancers overall. Hypothesis 2: There are inverse associations between coffee and the risk of the following diseases: head and neck cancer, esophageal SCC, breast cancer, cervical cancer, endometrial cancer, kidney cancer, and glioma. Hypothesis 3: There are no associations between coffee and the risk of the following diseases: esophageal adenocarcinoma, stomach cancer, lung cancer, ovarian cancer, prostate cancer, bladder cancer, testicular cancer and thyroid cancer. Specific aim 2: To examine whether tea intake is associated with the risk of cancer overall, and with the risk of specific cancer sites. Hypothesis 4: Tea intake is not associated with cancer overall. Hypothesis 5: Tea consumption is protective against ovarian and breast cancer. Hypothesis 6: Tea consumption is not associated with head and neck cancer or lung cancer. Specific aim 3: To explore differences in cancer risk for caffeinated vs. decaffeinated tea/coffee and addition of sugar, artificial sweeteners, non-dairy creamer, cream and milk. Hypothesis 7: Caffeinated coffee or tea intake, but not decaffeinated coffee or tea intake will have protective effects against head and neck cancer, esophageal SCC, breast cancer, endometrial cancer, kidney cancer, and glioma. Hypothesis 8: Addition of sugar, artificial sweeteners, non-dairy creamer, cream and milk in coffee or tea will not affect the associations between coffee/tea and the risk of cancer. Specific aim 4: To assess whether caffeine intake is associated with cancer risk. Hypothesis 9: Caffeine intake is not associated with cancer overall or with any of the specific sites of cancer that have been associated with coffee or tea intake. We propose to exclude examination of pancreatic cancer, hepatocellular carcinoma, colorectal cancer and colorectal adenoma in this current proposal, since examining coffee and the risk of these cancers has already been proposed in other projects.
