April: Polyp Prevention Trial Finds Low-Fat, High Fiber Diet Does Not Influence Risk of Recurrence of Colorectal Adenomas
The Polyp Prevention Trial tested the hypothesis that dietary intervention can inhibit the development of recurrent colorectal adenomas, the precursors of most large-bowel cancers. The study results found that adopting a diet that is low in fat and high in fiber, fruits, and vegetables does not influence the risk of recurrence of colorectal adenomas. The primary objective was to determine whether a low fat, high fiber, high vegetable and fruit eating plan would decrease the recurrence of adenomatous polyps of the large bowel. Secondary objectives were to: evaluate effectiveness of the intervention program with respect to participant achievement of dietary goals; examine dietary changes and associated biochemical markers in blood; and assess impact on quality of life.
July: Selenium and Vitamin E Cancer Prevention Trial (SELECT) Begins Recruiting Men
The SELECT starts recruiting men over the age of 55 to test the effectiveness of these two dietary supplements as prostate cancer prevention agents.

The first 20 years of the NCI Community Clinical Oncology Program (CCOP), the precursor to the NCI Community Oncology Research Program (NCORP), are documented.
December: Adenoma Prevention with Celecoxib (APC) Trial Suspended
The APC clinical trial is suspended based on an increased incidence of major cardiovascular events in participants taking celecoxib (Celebrex®). Other NCI trials continue with a revision to consent forms, and research into the benefits of celecoxib continues. Despite suspension of the trial and obvious negative side effects, the DCP observes 33% to 45% fewer adenomas in those within the APC trial, indicating further research possibilities such as anti-inflammatory pathways.
November: Results of the Breast Cancer Prevention Trial (BCPT) Updated
Updated BCPT results show a continued reduction of invasive breast cancer incidence as well as a decrease in some negative side effects. These side effects, first noted following the 1998 study, include increased risk of stroke, pulmonary embolism, and deep vein thrombosis.
February: Low-Fat Diet May Have Small Impact on Breast Cancer in Women
Results from the Women's Health Initiative (WHI) Dietary Modification (DM) prevention study show that reducing dietary fat and increasing fruits, grains, and vegetables may reduce risk of invasive breast cancer in some women, but has no effect on invasive colorectal cancer. Although more than 19,500 postmenopausal women followed the modified diet, the overall breast cancer risk reduction of 9% was not statistically significant after an average of 8.1 years. Women whose diets were highest in fat before they entered the study, however, were 22% less likely to develop breast cancer than the comparison group.
April: Initial Results of the Study of Tamoxifen and Raloxifene (STAR) Released
Initial results of the STAR clinical trial show that postmenopausal women who are at increased risk of breast cancer can reduce their risk of developing the disease if they take the drug raloxifene, an antiestrogen agent already approved by the Food and Drug Administration for the treatment and prevention of osteoporosis. Mature results from STAR later show that raloxifene is somewhat less effective than tamoxifen in preventing breast cancer but that it also has less toxicity, including a substantially lower risk of endometrial cancer.
January: Low-Fat Diet May Help Prevent Breast Cancer Recurrence
Findings from the NCI-sponsored Women's Intervention Nutrition Study (WINS) was published. Interim results from the first large-scale randomized clinical trial testing an intervention show that women who reduce their consumption of fat after treatment for early-stage breast cancer may also reduce their risk of a breast cancer recurrence.
July: Adopting Diet High in Vegetables, Fruit, Fiber, Low in Fat Did Not Reduce Breast Cancer Events or Mortality for Early Stage Breast Cancer Survivors
The published results of the Women's Healthy Eating and Living (WHEL) randomized trial show that among survivors of early stage breast cancer, adoption of a diet that was very high in vegetables, fruit, and fiber and low in fat did not reduce additional breast cancer events or mortality during a 7.3-year follow-up period.
October: Initial results from the Selenium and Vitamin E Cancer Prevention Trial (SELECT) Released
Initial results from the SELECT clinical trial indicate that selenium and vitamin E do not contribute to the prevention of prostate cancer. In fact, test results suggest a slight increase in prostate cancer incidence in subjects taking vitamin E.
March: Prostate Results from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial Released
Results from the PLCO trial show that screening men 55 years of age and older with PSA tests and digital rectal exams was not effective in reducing prostate cancer mortality.

In addition, false-positive results from the two screening methods often led to unnecessary surgeries and other serious complications.
October: Lung Results from the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial Released
PLCO clinical trial results show that annual screening for lung cancer using a standard chest x-ray does not reduce the risk of dying from lung cancer when compared with no annual screening.
January: Prostate Data Updated from the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial
PLCO trial data show that after 13 years of follow-up, men who underwent annual prostate cancer screening with prostate-specific antigen (PSA) testing and digital rectal examination had a 12% higher incidence of prostate cancer than men in the control group, but had the same rate of death from the disease. No evidence of a mortality benefit from screening was seen in subgroups defined by age, the presence of other illnesses, or pre-trial PSA testing.
May: Colorectal Results from the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial Released
Results of the PLCO trial confirm that screening people 55 years of age and older for colorectal cancer using flexible sigmoidoscopy reduces colorectal cancer incidence and mortality. In the PLCO, screened individuals had a 21% lower risk of developing colorectal cancer and a 26% lower risk of dying from the disease than the control subjects.
June: NCI Community Oncology Research Program (NCORP) Approved for Start
NCORP is approved by the NCI Board of Scientific Advisors, opening the way for the program to bring state-of-the art cancer prevention, control, treatment and imaging clinical trials, cancer care delivery research, and disparities studies to individuals in their own communities. It replaces, but expands on the success of the Community Clinical Oncology Program (CCOP), including the Minority-Based CCOPs; supersedes, but adds elements of the NCI Community Cancer Centers Program (NCCCP); and creates a network for cancer care delivery research.
August: Prostate Cancer Prevention Trial (PCPT) Findings Updated
Based on follow-up of trial participants for up to 18 years, the PCPT updated findings show that survival of the men on finasteride is equivalent to men who did not take the drug, and the reduction in risk of prostate cancer persists.
December: National Lung Screening Trial (NLST) Researchers Issue Finding on Overdiagnosis
A detailed analysis of the primary NLST findings showed that screening can detect slow-growing tumors that otherwise may not cause clinical symptoms, and can lead to overdiagnosis. The probability was 18.5% that any lung cancer detected by screening with low-dose CT was an overdiagnosis, and 22.5% that a non-small cell lung cancer, the most common form, detected by low-dose CT was an overdiagnosis. Overdiagnosis represents the potential harm of additional cost, anxiety, and morbidity associated with treatment.
February: Selenium and Vitamin E Cancer Prevention Trial (SELECT) Findings Updated
In an update, SELECT researchers report that men who had high levels of selenium at the start of the trial, as assessed by measures of selenium in their toenail clippings, had almost double the chance of developing a high-grade prostate cancer if they took the selenium supplement compared to men with low levels of selenium at the start of the trial. Additionally, men with low selenium levels at the start of the trial had double the chance of developing a high-grade prostate cancer if they took the vitamin E supplement.
