Feasibility of collecting tumor samples of breast cancer patients diagnosed up to 50 years ago in the Child Health and Development Studies.

ABSTRACT: Environmental exposures during pregnancy may increase breast cancer risk for mothers and female offspring. Tumor tissue assays may provide insight regarding the mechanisms. This study assessed the feasibility of obtaining tumor samples and pathology reports from mothers (F0) who were enrolled in the Child Health and Development Studies during pregnancy from 1959 to 1967 and their daughters (F1) who developed breast cancer over more than 50 years of follow-up. Breast cancer cases were identified through linkage to the California Cancer Registry and self-report. Written consent was obtained from 116 F0 and 95 F1 breast cancer survivors to access their pathology reports and tumor blocks. Of those contacted, 62% consented, 13% refused and 24% did not respond. We obtained tissue samples for 57% and pathology reports for 75%, and if diagnosis was made ?10 years we obtained tissue samples and pathology reports for 91% and 79%, respectively. Obtaining pathology reports and tumor tissues of two generations is feasible and will support investigation of the relationship between early-life exposures and molecular tumor markers. However, we found that more recent diagnosis increased the accessibility of tumor tissue. We recommend that cohorts request consent for obtaining future tumor tissues at study enrollment and implement real-time tissue collection to enhance success of collecting tumor samples and data.

Project description:Background: Physicians are frequently not aware that patients may not be familiar with the meaning of medical terms or have limited knowledge about the location of organs. These aspects of functional health competence require particular attention when designing communication curricula for undergraduate medical students. The aim of our study was to evaluate the knowledge of laypersons about the anatomical locations of organs and the definitions of commonly used medical terms as relevant aspects of health literacy. Furthermore, we wished to compare it with the knowledge of a historical patient cohort who performed this study 50 years ago. Methods: In this replication study, multiple-choice questionnaires with simple anatomy and common medical terms which were published in 1970 were distributed among a convenience sample of lay volunteers (n=537) from the streets of Hamburg, Germany. Sociodemographic data including sex, age, highest educational school achievement, occupation in a field associated with medicine, and German as first language were also collected. The percentage of laypersons' correct answers was compared to the percentage of correct answers of a historical patient cohort (n=234) published in 1970 to identify the development of health literacy as basis for curricular planning. Results: Laypersons showed significantly more correct answers in four of eight simple anatomical locations of organs (p<0.001). For seven commonly used medical terms laypersons only gave significantly more correct answers for the definitions of "jaundice" (p<0.001) and "diarrhoea" (p=0.001) compared to the historical cohort from 1970. Participants with a senior high school degree performed significantly better with respect to total scores of correct organ locations (p<0.001, d=0.35) and correct definitions of medical terms (p=0.001, d=0.30) than participants who completed junior high school. Conclusion: The definitions of common medical terms and the correct anatomical locations of organs by laypersons have increased during the past 50 years but could still need improvement by school education and media information of better quality. Medical educators should know about the low health literacy of laypersons with respect to these aspects to raise medical students' awareness for this problem and to provide communication training for medical students to use comprehensible language during history taking and shared decision making.
