Reliability of self-reported information on skin cancer among elderly patients with squamous cell carcinoma

Head and Neck Region Dermatological Ultraviolet-Related Cancers are Associated with Exfoliation Syndrome in a Clinic-Based Population

OBJECTIVE

We assessed the relationship between ultraviolet (UV)-associated dermatological carcinomas (basal cell carcinoma [BCC] and squamous cell carcinoma [SCC]) and exfoliation syndrome (XFS) or exfoliation glaucoma (XFG).

DESIGN

Case-control study.

PARTICIPANTS

Between 2019 and 2021, 321 participants and control subjects (XFS or XFG = 98; primary open-angle glaucoma [POAG] = 117; controls = 106; ages 50-90 years) were recruited.

METHODS

A cross-sectional survey assessing medical history, maximum known intraocular pressure, cup-to-disc ratio, Humphrey visual field 24-2, the propensity to tan or burn in early life, history of BCC or SCC, and XFS or XFG diagnosis. The multivariable models adjusted for age, sex, medical history, eye color, hair color, and likeliness of tanning versus burning at a young age.

MAIN OUTCOME MEASURES

History of diagnosed XFS or XFG.

RESULTS

Any history of BCC or SCC in the head and neck region was associated with a 2-fold higher risk of having XFS or XFG versus having POAG or being a control subject (odds ratio [OR], 2.01; 95% confidence interval [CI], 1.04-3.89) in a multivariable-adjusted analysis. We observed a dose-response association in which the chance of having XFS or XFG increased by 67% per head and neck BCC or SCC occurrence (OR, 1.67; 95% CI, 1.09-2.56). When we excluded POAG participants, head and neck BCC or SCC was associated with a 2.8-fold higher risk of XFS or XFG (OR, 2.80; 95% CI, 1.12-7.02), and each additional occurrence had a 2-fold higher risk of XFS or XFG (OR, 1.97; 95% CI, 1.09-3.58). The association between head and neck region BCC or SCC and POAG compared with the control subjects was null (OR, 1.42; 95% CI, 0.58-3.48). With BCC or SCC located anywhere on the body, there was a nonsignificantly higher risk of having XFS or XFG compared with having POAG or being a control subject (OR, 1.65; 95% CI, 0.88-3.09).

CONCLUSIONS

Head and neck region BCCs or SCCs are associated with a higher risk of having XFS or XFG. These findings support prior evidence that head and neck UV exposure may be a risk factor for XFS.

History of keratinocyte carcinoma and survival after a second primary malignancy: the Moffitt Cancer Center patient experience

PURPOSE

History of keratinocyte carcinoma (KC) has been associated with survival following the diagnosis of a second primary malignancy (SPM), with the direction of the association varying by cancer type. Research is needed to elucidate the role of other key factors in this association.

METHODS

A retrospective cohort study was conducted among patients newly diagnosed and/or treated at Moffitt Cancer Center in December 2008-April 2020 with breast cancer, lung cancer, melanoma, colon cancer, prostate cancer, and non-Hodgkin lymphoma/chronic lymphocytic leukemia (NHL/CLL) (n = 29,156). History of KC was obtained from new patient intake questionnaires. Age- and stage-adjusted hazard ratios (HR) and 95% confidence intervals (CI) were calculated to estimate the association between history of KC and survival following each cancer, stratified by demographic/clinical characteristics.

RESULTS

KC history was most prevalent in patients with melanoma (28.7%), CLL (19.8%) and lung cancer (16.1%). KC history was associated with better overall survival following prostate cancer (HR = 0.74, 95% CI = 0.55-0.99) and poorer overall survival following CLL (HR = 1.73, 95% CI = 1.10-2.71). Patients with a history of KC experienced better survival within the first four years of a melanoma diagnosis (HR = 0.79, 95% CI = 0.67-0.92); whereas poorer survival was observed for patients who survived 7 + years after a melanoma diagnosis (HR = 2.18, 95% CI = 1.17-4.05). Stratification by treatment and stage revealed directional differences in the associations between KC history and survival among patients with breast cancer and melanoma.

CONCLUSIONS

KC history may be a predictor of survival following an SPM, possibly serving as a marker of immune function and/or DNA damage repair capacity.

Patients and Methods of the PATH Biobank - A Resource for Breast Cancer Research

Introduction: The foundation PATH (Patients' Tumour Bank of Hope) collects in a tumour bank samples of blood, tumour, and tumour-near normal tissue from breast cancer patients and supplements them systematically with health-care data. Material and Methods: For patients from the diagnosis years 2006-2009 quantitative data were evaluated with the help of mean values and standard deviations while for qualitative data absolute and relative incidences were assessed. Demographic and clinical features of women who used different numbers of information sources were tested for statistical significance by means of ANOVA and χ² tests. The benchmark report of the WBC and two DMP reports were used to compare oncological care. Results: For research purposes tumour tissue samples are available for 59 % of the cases, normal tissue for 62 % and blood serum samples for 92 %. From 3573 women (diagnoses 2006-2009), a total of 2697 women (75.5 %) took part in follow-up. The characteristics of the follow-up patients did not relevantly differ from those of all the patients. The responsible physician was named as the most important source of information about the disease. Young women in particular consulted several sources and also used the internet to obtain information. Discussion: Compared with data on therapy from WBC and the DMP breast cancer in Bavaria or, respectively, North Rhineland reports, the PATH patients represent an only slightly selected sample. The PATH biobank is a (still) poorly used data and sample source, which is made available upon request and positive evaluation of the study protocol. Thus, it is possible to address current questions in a short time without having to undertake extensive recruiting procedures.

Elderly Men's Experience of Information Material about Melanoma-A Qualitative Study

Malignant melanoma is an aggressive disease that has been increasing worldwide. Public education is trying to focus on reducing intense sun exposure and raise awareness of signs and symptoms to prevent illness. The aim of the study was to describe and analyze elderly men's (over 65 years) experience of an information booklet regarding malignant melanoma. The study comprised of a total of 15 interviews with elderly men. The interviews were analyzed using manifest qualitative content analysis. Respect for the individuals was a main concern in the study. One category, Security-to act, and three subcategories, Availability-to use, Clarity-to understand, and Awareness-to know, were identified to describe the men's experiences of information material about melanoma. By using person-centered care, based on a holistic approach focusing on men's need for security to act on specific risk factors and to do skin self-examination, health could be improved. The results of this study could help other health organizations to develop information material to prevent illness, such as for skin self-examination. Strategies concerning educating, preparing, and training health professionals in interpersonal communication skills should be implemented in healthcare organizations to meet patients' information needs about illness to develop continuous learning and quality improvement.

Reliability of self-report on basic health conditions in Mexican Americans Age 80 and older

Reliability of self-reports in survey research is important. Little is known about the reliability of self-reports in the very old (aged 80+). The objective of this study is to evaluate the level of reliability in self-reports by assessing the level of agreement between a "respondents" and their "informants" (children) as they rate the respondent's: hearing ability; vision capacity; and nine health conditions. Descriptive statistics, observed agreement, and kappa values are computed on 389 pairs using HEPESE Wave-7 data (2010-2011). Although further studies are required, there is evidence that self-reports on basic health conditions in the very old are reliable.
