Responsiveness of the Spanish Version of the "Skin Cancer Index"

Cross-cultural adaptation of the Skin Cancer Index into Brazilian Portuguese for patients with cervicofacial nonmelanoma skin cancer

PURPOSE

This study aimed to translate the Skin Cancer Index (SCI) into Portuguese, adapt it for Brazilian culture, and clinically validate it.

METHODS

A five-stage cross-cultural adaptation model was followed, with subsequent clinical validation. Inter-rater agreement was assessed using the content validity index (CVI). The hypothesis of the non-inferiority of the CVI at 80% probability level was evaluated using an exact binomial test. We used Spearman's rank-order and Pearson's product-moment correlation analysis, internal consistency using McDonald's ω and Cronbach's α metric, and construct validity using confirmatory factor analysis. The factorial model was validated using the chi-squared test, root mean square error of approximation (RMSEA), comparative fit index (CFI), and standardized root mean square residual (SRMR).

RESULTS

The first stage yielded two independent translations. After synthesis, back-translation, and review, the prefinal version was tested on 40 patients. Inter-rater agreement indices on content validity were significantly higher than 80% (p < 0.05). The SCI remained stable, and the Spearman's rank-order (rs), Pearson product-moment (r), and intraclass correlation coefficients were > 0.9, indicating excellent reliability. The reliability of McDonald's ω was considered ideal (> 0.8) in all subdimensions and scale. Cronbach's α was considered ideal in the "Emotional" and "Social" subdimensions and scale. Construct validity was observed in all subdimensions and scale through the criteria (χ2) p value > 0.05, RMSEA < 0.08, CFI ≥ 0.9, and SRMR ≤ 0.08.

CONCLUSION

The cross-cultural adaptation of the SCI to Portuguese for Brazilian culture showed content validity and reliability, contributing to quality of life assessment in patients with NMSC.

Quality of Life During Treatment for Cervicofacial Non-melanoma Skin Cancer

Non-melanoma skin cancer (NMSC), despite its low mortality, can impose a significant psychological burden on patients. The aim of the present study is to examine the evolution of the quality of life (QOL) in patients with cervicofacial NMSC during treatment. This prospective cohort study was conducted to a group of patients with cervicofacial NMSC, confirmed by skin biopsy. These patients completed the Skin Cancer Index questionnaire at the time of diagnosis and at 1 week, 1 month and 6 months after treatment began. Data for these patients' demographic characteristics and variables related to the type of tumour, the treatment received and the evolution of the condition were recorded. The study group was composed of 220 patients. At the time of diagnosis, the overall mean score for QOL was 54.1 (SD 21.9); for the social appearance component, it was 76.7 (SD 26.2), and for the emotional component, it was 23 (SD 25.1). Six months after treatment began, the overall mean score was 61 (SD19.1), that for social appearance, 85 (SD 20.6), and that for the emotional component, 27.4 (SD 26.6). All the differences were statistically significant (p < 0.05). The results obtained show that during the treatment period, it is at the time of diagnosis when patients with cervicofacial NMSC undergo the greatest deterioration in their QOL. In comparison with the findings obtained in previous studies, our population obtained lower overall scores in the questionnaires and less improvement during follow-up.

Comparison of the Skin Cancer Quality of Life Impact Tool and the Skin Cancer Index Questionnaire in Measurement of Health-Related Quality of Life and the Effect of Patient Education Brochures in Patients with Actinic Keratosis, Non-melanoma Skin Cancer, and Cutaneous Melanoma

Introduction

Few studies have evaluated patient-reported outcome measures and the effect of patient educational materials in German patients with skin cancer. We conducted a prospective study to measure the impact of treatment on health-related quality of life in German patients with skin cancer, identify variables that may contribute to changes in health-related quality of life, and evaluate the effect of providing additional information through a patient education brochure.

Methods

A total of 461 patients diagnosed with actinic keratosis, nonmetastatic nonmelanoma skin cancer, melanoma in situ, or nonmetastatic cutaneous melanoma treated between August 2018 and July 2020 were included. Ninety-seven patients were randomly selected to receive an additional patient education brochure (“Hautkrebs”). The patients completed a Skin Cancer Quality of Life Index Tool (n = 324) or a Skin Cancer Index Questionnaire (n = 137) 1 week after surgical treatment.

Results

Ninety-seven patients were provided an additional patient education brochure. We found statistical correlation between sociodemographic factors (young age and female gender) and the location of the skin cancer (head and face) and impairment of health-related quality of life in patients with skin cancer (p < 0.05). Moreover, we found that patients who were presented a brochure showed significantly higher awareness concerning direct sun exposure (p < 0.05).

Conclusion

Impaired health-related quality of life is correlated with a patient with skin cancer’s age, gender, and the location of the lesion. Physicians should consider these factors in clinical practice and advocate the use of patient education brochures as effective assets in preventing the reoccurrence of skin cancer.

Factors related to the evolution of quality of life in patients with cervicofacial non-melanoma skin cancer

PURPOSE

Non-melanoma skin cancer (NMSC) is the most frequent neoplasm today, worldwide. This type of tumour presents low mortality but causes a major psychosocial impact on the patient. Studies have shown that the patient's quality of life (as detected by questionnaire scores in this respect) improves as the care process advances. The main aim of the present study is to identify the factors that are related to this favourable evolution.

METHODS

This descriptive cross-sectional study included patients with cervicofacial NMSC, confirmed by skin biopsy. The patients were asked to complete the Skin Cancer Index questionnaire at the time of diagnosis and subsequently at 1 week, 1 month and 6 months after treatment. Relevant demographic variables were recorded, together with information on health status and the treatment received.

RESULTS

A total of 229 patients with biopsy-confirmed cervicofacial NMSC were included in the study population, and 220 completed the quality of life questionnaires at the necessary time points during the care process. Some variables-sex, education, marital status, history of anxiety or depression, tumour type, the treatment received and the VAS score in this respect-were found to have a statistically significant influence on the degree of improvement recorded in the quality of life questionnaire scores during follow-up.

CONCLUSIONS

The quality of life questionnaire scores of patients with cervicofacial NMSC improve following treatment, but this progression is not homogeneous among patients. We identify the variables that are related to a greater degree of improvement on the questionnaire scales (overall, emotional and social-aesthetic).
