Feasibility of a telephone survey to recruit health maintenance organization members into a tamoxifen chemoprevention trial.

A large-scale, nationwide tamoxifen chemoprevention trial is currently being planned as a primary preventive strategy against breast cancer. The recruitment of health asymptomatic women into a long-term clinical trial will pose unique recruitment problems. This study examines the feasibility of telephone recruitment from a health maintenance organization population into such a trial. A random sample of 203 women aged 50 and older with a personal family history of breast cancer were contacted by telephone. A structured interview was administered to assess self-perceived risk of breast cancer, willingness to participate in a trial, and anticipated barriers to participation. Of the 203 names generated from the health maintenance organization membership roster 128 (63%) met eligibility criteria and participated in the interview. Forty-five % of the eligible women expressed interest in the tamoxifen trial. Women who felt that their family would support their participation expressed significantly more interest, while concern about possible side effects emerged as potential barriers. We conclude that contact by telephone among health maintenance organization members can identify a significant proportion of women who are interested in primary chemoprevention for breast cancer. Participation rates may be improved by bolstering family support and by addressing concerns about drug toxicity.

Trials of single-agent and combination chemotherapy for advanced cancer of the pancreas.

In a study of 127 patients with advanced measurable pancreatic cancer, objective response rates of 2% (melphalan), 10% (5-FU and methyl-CCNU), and 7% (5-FU, methyl-CCNU, and streptozocin) were achieved. No responses occurred in the 28 patients treated with VP-16-213 who had already received prior chemotherapy. Toxicity was greater for the two- and three-drug combinations than for melphalan. There was no difference in survival following use of the three treatment regimens. Further studies are needed to develop effective chemotherapy for patients with cancer of the pancreas.

Recruiting high risk women into a breast cancer health promotion trial.

This study sought to identify factors that facilitate or hinder participation in a breast cancer health promotion trial among high-risk women. The subjects were 271 women ages 35 years and older who had a family history of breast cancer in at least one first-degree relative. All subjects were eligible for participation in a randomized trial which compares breast cancer risk counseling with general health counseling. Structured telephone interviews evaluated demographic characteristics, risk factors, risk perceptions, breast cancer concerns, and past screening practices. The results showed that education level was a key determinant of the importance of these factors in participation. Logistic regression modeling indicated that women with a high school education or less were most likely to participate if: (a) their relatives' diagnoses had greatly increased their perceptions of their personal risks [OR (OR) = 4.1], particularly if they perceived that risk to be very high (OR for interaction = 6.4); and (b) if they were ages 40-49 years versus 35-39 or 50 + years (OR = 2.6). By contrast, among women with education beyond high school, participation was predicted by (a) marital status (OR = 2.6), (b) employment (OR = 0.03 for employed), (c) number of affected relatives (OR = 0.07 for 1 versus 2 first-degree relatives), and (d) previous biopsy (OR = 0.42). These findings suggest that recruitment strategies that tailor messages to women's educational levels might be most effective.
