The Mean

ObjectivesTo validate the self-reported diagnoses of gynaecological and breast cancers in a nationwide prospective cohort study of nursing professionals: the Japan Nurses’ Health Study (JNHS).Design and settingRetrospective analysis of the JNHS.Participants and measuresData were reviewed for 15 717 subjects. The mean age at baseline was 41.6±8.3 years (median: 41), and the mean follow-up period was 10.5±3.8 years (median: 12). Participants are regularly mailed a follow-up questionnaire once every 2 years. Respondents who self-reported a positive cancer diagnosis were sent an additional confirmation questionnaire and contacted the diagnosing facility to confirm the diagnosis based on medical records. A review panel of experts verified the disease status. Regular follow-up, confirmation questionnaires and expert review were validated for their positive predictive value (PPV) and negative predictive value (NPV).ResultsNew incidences were verified in 37, 47, 26 and 300 cervical, endometrial, ovarian and breast cancer cases, respectively. The estimated incidence rates were 22.0, 25.4, 13.8 and 160.4 per 100 000 person-years. These were comparable with those of national data from regional cancer registries in Japan. For regular follow-up, the corresponding PPVs for cervical, endometrial, ovarian and breast cancer were 16.9%, 54.2%, 45.1% and 81.4%, and the NPVs were 100%, 99.9%, 99.9% and 99.9%, respectively. Adding the confirmation questionnaire improved the PPVs to 31.5%, 88.9%, 76.7% and 99.9%; the NPVs were uniformly 99.9%. Expert review yielded PPVs and NPVs that were all ~100%.ConclusionsGynaecological cancer cannot be accurately assessed by self-reporting alone. Additionally, the external validity of cancer incidence in this cohort was confirmed.

Abstract Background Cancer registries usually assess data of conventional treatments and/or patient survival. Beyond that, little is known about the influence of other predictors of treatment response related to the use of complementary therapies (CM) and lifestyle factors affecting patients’ quality and quantity of life. Methods INTREST is a prospective cohort study collecting register data at multiple German certified cancer centers, which provide individualized, integrative, in- and outpatient breast cancer care. Patient-reported outcomes and clinical cancer data of anticipated N = 715 women with pTNM stage I-III breast cancer are collected using standardized case report forms at the time of diagnosis, after completing neo−/adjuvant chemotherapy, after completing adjuvant therapy (with the exception of endocrine therapy) as well as 1, 2, 5, and 10 years after baseline. Endpoints for multivariable prediction models are quality of life, fatigue, treatment adherence, and progression-based outcomes/survival. Predictors include the study center, sociodemographic characteristics, histologic cancer and comorbidity data, performance status, stress perception, depression, anxiety, sleep quality, spirituality, social support, physical activity, diet behavior, type of conventional treatments, use of and belief in CM treatments, and participation in a clinical trial. Safety is recorded following the Common Terminology Criteria for Adverse Events. Discussion This trial is currently recruiting participants. Future analyses will allow to identify predictors of short- and long-term response to integrative breast cancer treatment in women, which, in turn, may improve cancer care as well as quality and quantity of life with cancer. Trial registration German Clinical Trial Register DRKS00014852. Retrospectively registered at July 4th, 2018.
