Development of the facial skin care index: a health-related outcomes index for skin cancer patients

Advanced basal cell carcinoma treated with vismodegib: impact on the lives of patients and their families

Locally advanced basal cell carcinoma (laBCC) represented an uncommon, difficult-to-treat form of skin cancer until the recent approval of the Hedgehog inhibitor vismodegib. Approximately 80% of laBCCs occur in the head and neck region, causing disfiguring skin changes that have an impact on patient quality of life (QoL). Because the lives of patients with advanced BCCs are severely disrupted, it would be expected that the QoL family members involved in caregiving would also be affected. The aim of our study was to quantify the QoL of both patients and family members during vismodegib treatment using the Dermatology Life Quality Index and the Family Dermatology Life Quality Index, respectively.

Long-Term Efficacy of Vismodegib After its Withdrawal and Patients' Health-Related Quality of Life Using the Dermatology Life Quality Index (DLQI)

INTRODUCTION

Although non-melanoma skin cancers (NMSCs) are associated with a very low mortality risk, they have been reported to have a major impact on patients' health-related quality of life (HRQoL). Vismodegib is a therapy for patients who are affected by locally advanced basal cell carcinoma (BCC) or metastatic BCC who are ineligible for surgery and/or radiotherapy. The aim of the present clinical study was to assess the long-term efficacy of vismodegib after its withdrawal by evaluating the recurrence rate of advanced BCC, assessing also patients' HRQoL after 3 and 6 months from drug withdrawal.

METHODS

A retrospective study was performed to analyze patients with advanced and/or multiple BCCs that had been treated with vismodegib (150 mg daily) at the Non-Melanoma Skin Cancer Unit of the University of Naples Federico II (Italy) and had obtained a complete regression in 6 months. At the end of the 6-month treatment cycle, patients that reported total remission of the skin tumor were visited monthly in order to assess their therapeutic response. Moreover, to assess the specific impact of vismodegib on HRQoL, DLQI was administered before vismodegib treatment (baseline), at the end of the therapy cycle (6 months), as well as after 3 and 6 months from vismodegib discontinuation.

RESULTS

Thirty-five patients (27 male, 8 female), with a complete regression of their advanced BCC after vismodegib treatment, were included in the study. The duration of treatment for all patients was 6 months as set by study inclusion criteria. A BCC recurrence rate of 31% (11/35) was reported after a 6-month follow-up. The average reported Dermatology Life Quality Index (DLQI) score increased from a value of 0 at the end of the 6-month vismodegib treatment to a mean value of 2.4 after 3 months from drug withdrawal and 3.6 after 6 months from treatment discontinuation.

CONCLUSION

The results of this exploratory analysis of vismodegib withdrawal are consistent with a substantial link between treatment response and patients' HRQoL. Furthermore, 11 out of 35 (31%) patients that reported a complete remission of the disease after 6 months of vismodegib treatment reported BCC recurrence. These data highlight the importance of continuous follow-up and perhaps different regimens of treatment, such as an alternate dose regimen to maintain disease control and reduce the adverse events as previously described in the literature.

Long-Term Efficacy of Vismodegib After its Withdrawal and Patients' Health-Related Quality of Life Using the Dermatology Life Quality Index (DLQI)

Real-Life Effectiveness of Vismodegib in Patients with Metastatic and Advanced Basal Cell Carcinoma: Characterization of Adverse Events and Assessment of Health-Related Quality of Life using the Dermatology Life Quality Index (DLQI) Test

INTRODUCTION

Non-melanoma skin cancer (NMSC) is the most common type of human tumor, with an estimated five million new cases each year. NMSC has been described as having a major impact on the health-related quality of life of the patient. Vismodegib is a hedgehog pathway inhibitor therapy for patients who are affected by locally advanced basal cell carcinoma (laBCC) and metastatic basal cell carcinoma and are ineligible for surgery and/or radiotherapy. The objective of this study was to assess treatment-emergent adverse events reported by patients with advanced BCC who were undergoing hedgehog pathway inhibitor therapy with vismodegib, and to quantify their health-related quality of life using the Dermatology Life Quality Index (DLQI) questionnaire.

METHODS

Patients with advanced and/or multiple basal cell carcinomas treated with vismodegib at the Non-Melanoma Skin Cancer Unit of the University of Naples Federico II (Italy) were consecutively enrolled. Each patient was evaluated every month until the end of the treatment cycle to assess adverse events related to the drug and the patient's quality of life.

RESULTS

48 patients (35 males and 13 females) with advanced BCC were included in the study. Muscle spasms, alopecia, and dysgeusia were the most frequently reported adverse events. 41 patients completed the DLQI questionnaire at the baseline visit and after 6 months of treatment. The average reported DLQI score decreased from a mean value of 5.7 at the baseline visit to 0.4 after 6 months of treatment.

CONCLUSION

This is the first study to demonstrate a significant change in patient health-related quality of life from baseline to 6 months after hedgehog pathway inhibitor therapy initiation using the DLQI test. Interestingly, patients with BCC in visible areas such as the face or neck presented an overall DLQI score that was higher than that of patients with BCC located on the trunk and legs at the baseline visit, but the DLQI scores of these two groups were almost the same after 6 months of vismodegib therapy.

Keratinocyte carcinoma as a chronic disease in Australia and Spain: The importance of avoidance of perceived visible scars

BACKGROUND/OBJECTIVES

Keratinocyte cancer impacts health-related quality of life (HRQL). Disease progression and treatment can lead to adverse physical and psychosocial consequences. The skin cancer index (SCI) is a validated tool with higher scores reflecting greater HRQL. Our objectives were to assess and compare the impact of keratinocyte cancer using the SCI in two diverse populations.

METHODS

A total of 120 patients were prospectively recruited from dermatology clinics in Sydney, Australia, and Santander, Spain, providing demographics and completing the SCI.

RESULTS

About 61.1% of Australians reported ≥2 skin cancers (vs 20% P = <0.001), 44.4% resulting visible scars (vs 14.8% P = <0.001). Visible scars were associated with poorer HRQL, across total SCI (68.3 vs 81.5 P = <0.001), social (76.0 vs 86.7 P = 0.003) and emotional (54.2 vs 69.7 P = 0.003) domains. Interestingly, perceived visible scars were not associated with appearance scores. The Spanish population reported greater appearance (88.0 vs 75.6 P = 0.008) and emotional (70.7 vs 60.5 P = 0.034) HRQL. Surprisingly, incidence of cancer, recent disease, gender and education were not associated with HRQL impairment.

CONCLUSIONS

Australians with keratinocyte cancer experience poorer HRQL compared to a Spanish population. Offering non-surgical means when amenable and consideration of psychosocial needs during clinical course is emphasised. While our study highlights the importance of HRQL tools, our results question the sensitivity of the SCI across populations. Further research is required to substantiate its ongoing use.

Quality of life measurement in skin cancer patients: literature review and position paper of the European Academy of Dermatology and Venereology Task Forces on Quality of Life and Patient Oriented Outcomes, Melanoma and Non-Melanoma Skin Cancer

The European Academy of Dermatology and Venereology (EADV) Task Forces (TFs) on Quality of Life (QoL) and Patient Oriented Outcomes, Melanoma and Non-Melanoma Skin Cancer (NMSC) present a review of the literature and position statement on health-related (HR) QoL assessment in skin cancer patients. A literature search was carried out to identify publications since 1980 that included information about the impact of SC on QoL. Generic, dermatology-specific, cancer-specific, SC-specific, facial SC-specific, NMSC-specific, basal cell carcinoma-specific and melanoma-specific QoL questionnaires have been used to assess HRQoL in SC patients. HRQoL was assessed in the context of creation and validation of the HRQoL instruments, clinical trials, comparison of QoL in SC and other cancers, other diseases or controls, HRQoL assessment after treatment, comorbidities, behaviour modification, predictors of QoL and survival, supportive care needs, coping strategies and fear of cancer recurrence. The most widely used instruments for HRQoL assessment in SC patients are the European Organisation for Research and Treatment of Cancer Core Questionnaire (EORTC QLQ-C30), the Functional Assessment of Cancer Therapy-Melanoma (FACT-M), Skin Cancer Index (SCI), Short Form 36 Item Health Survey (SF-36) and the Dermatology Life Quality Index (DLQI). The TFs recommend the use of the cancer-specific EORTC QLQ-C30, especially in late stages of disease, and the melanoma-specific FACT-M and SC-specific SCI questionnaires. These instruments have been well validated and used in several studies. Other HRQoL instruments, also with good basic validation, are not currently recommended because the experience of their use is too limited. Dermatology-specific HRQoL instruments can be used to assess the impact of skin-related problems in SC. The TFs encourage further studies to validate HRQoL instruments for use in different stages of SC, in order to allow more detailed practical recommendations on HRQoL assessment in SC.

Patient-reported outcome measures for facial skin cancer: a systematic review and evaluation of the quality of their measurement properties

BACKGROUND

Skin cancer is the commonest malignancy worldwide, often occurring on the face. Both the condition and treatment can lead to scarring and facial disfigurement, affecting a patient's health-related quality of life (HRQoL), which can be measured using patient-reported outcome measures (PROMs).

OBJECTIVES

This systematic review identifies PROMs for facial skin cancer and appraises their methodological quality and psychometric properties using up-to-date methods.

METHODS

MEDLINE, Embase, PsycINFO, Cochrane and CINAHL were searched systematically in accordance with PRISMA guidelines, identifying all PROMs designed for or validated in facial skin cancer. Methodological quality and evidence of psychometric properties were assessed using the COnsensus-based Standards for the Selection of Health Measurement INstruments (COSMIN) checklist and criteria proposed by Terwee and colleagues. A best-evidence synthesis and assessment of instrument focus on post-resection reconstruction was also performed.

RESULTS

We included 24 studies on 11 PROMs. Methodological quality and psychometric evidence was variable, with the Patient Outcome of Surgery - Head/Neck (POS-H/N), Skin Cancer Index (SCI), Skin Cancer Quality of Life Impact Tool (SCQOLIT) and Essers and colleagues demonstrating the greatest level of validation. None scored well in their relevance to post-skin cancer reconstruction of the face.

CONCLUSIONS

This systematic review critically appraises PROMs for facial skin cancer using internationally accepted criteria. The identified PROMs demonstrate a variation in the quality of validation performed, with a need to improve this across all PROMs in the field. Only through improving the quality of available PROMs and their focus on the post-treatment aesthetic and functional outcome will we be able to truly appreciate the concerns of our patients and improve the management of facial skin cancer.

UK-based prospective cohort study to anglicise and validate the FACE-Q Skin Cancer Module in patients with facial skin cancer undergoing surgical reconstruction: the PROMISCR (Patient-Reported Outcome Measure in Skin Cancer Reconstruction) study

INTRODUCTION

Skin cancer is the most common malignancy worldwide, often occurring on the face, where the cosmetic outcome of treatment is paramount. A number of skin cancer-specific patient-reported outcome measures (PROMs) exist, however none adequately consider the difference in type of reconstruction from a patient's point of view. It is the aim of this study to 'anglicise' (to UK English) a recently developed US PROM for facial skin cancer (the FACE-Q Skin Cancer Module) and to validate this UK version of the PROM. The validation will also involve an assessment of the items for relevance to facial reconstruction patients. This will either validate this new measure for the use in clinical care and research of various facial reconstructive options, or provide evidence that a more specific PROM is required.

METHODS AND ANALYSIS

This is a prospective validation study of the FACE-Q Skin Cancer Module in a UK facial skin cancer population with a specific focus on the difference between types of reconstruction. The face and content validity of the FACE-Q questionnaire will initially be assessed by a review process involving patients, skin cancer specialists and methodologists. An assessment of whether questions are relevant and any missing questions will be made. Initial validation will then be carried out by recruiting a cohort of 100 study participants with skin cancer of the face pre-operatively. All eligible patients will be invited to complete the questionnaire preoperatively and postoperatively. Psychometric analysis will be performed to test validity, reliability and responsiveness to change. Subgroup analysis will be performed on patients undergoing different forms of reconstruction postexcision of their skin cancer.

ETHICS AND DISSEMINATION

This study has been approved by the West Midlands, Edgbaston Research Ethics Committee (Ref 16/WM/0445). All personal data collected will be anonymised and patient-specific data will only be reported in terms of group demographics. Identifiable data collected will include the patient name and date of birth. Other collected personal data will include their diagnosis, treatment performed, method of reconstruction and complications. A unique identifier will be applied to each patient so that pretreatment and post-treatment questionnaire results can be compared. All data acquisition and storage will be in accordance with the Data Protection Act 1998. Following completion of the study, all records will be stored in the Abertawe Bro Morgannwg University (AMBU) Health Board archive facility. Only qualified personnel working on the project will have access to the data.The outputs from this work will be published as widely as possible in peer-review journals and it is our aim to make this open access.

Validation of the English and French versions of the Brief Health Care Climate Questionnaire

Patient autonomy is a central value in medicine and critical component of adherence to medical advice. This article reports on a validation of the 6-item version of the Health Care Climate Questionnaire (HCCQ), a measure of autonomy support in health care settings, in a sample of 242 melanoma patients. The HCCQ showed excellent internal consistency (α = .91), structural validity (Tucker-Lewis index = .99; comparative fit index = .99; root mean square error of approximation = .06, 90 per cent confidence interval (.00, .11); standardized root mean square residual = .02; χ2 (8, N = 235) = 13.99, p = .08) and construct validity (92.31% of hypothesized correlations with other measures confirmed). Acceptable 3-month test-retest reliability was observed (r = .55, p < .001; intraclass correlation coefficient (A, 1) = .54, p < .001). The French version was found equivalent to the English version.

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

Background. Skin Cancer Index (SCI) is a specific questionnaire measuring health related quality of life (HRQL) in patients with cervicofacial non-melanoma skin cancer (CFNMSC). The original scale has recently been adapted and validated into Spanish. Objectives. Evaluate the responsiveness of the Spanish version of SCI. Methods. Patients with CFNMSC candidate for surgical treatment were administered the questionnaire at time of diagnostic (t₀), 7 days after surgery (t₁), and 5 months after surgery (t₂). The scale and subscales scores (C1: social/appearance, C2: emotional) were then evaluated. Differences between t₀-t₁, t₁-t₂, and t₀-t₂ were determined and a gender-and-age segmented analysis was performed. Results. 88 patients, 54.8% male, mean age 62.5 years, completed the study. Differences between t₀-t₁ and t₁-t₂ scores were statistically significant (p < 0.05). The lowest values were found at time of diagnosis and postsurgery. Women and patients under 65 years showed the lowest values at the three times. Limitations. Concrete geographic and cultural area. Clinical and histological variables are not analysed. Conclusions. Our results confirm responsiveness of the Spanish version of the SCI. Further development of the instrument in Spanish-speaking countries and populations will make it possible to extend worldwide research and knowledge horizons on skin cancer.

A structured review of patient-reported outcome measures for patients with skin cancer, 2013

BACKGROUND

The collection of patient-reported outcome measures (PROMs) within the national PROMs programme for elective procedures is now established mandatory practice in the NHS with high response rates and completion.

OBJECTIVES

This review examines the evidence of PROMs for people with skin cancer.

METHODS

Comprehensive searches were conducted using several sources and databases, using a detailed search strategy developed by the University of Oxford's PROM Group. Articles were assessed for eligibility. Data were extracted per PROM for each measurement property and appraised using an appraisal framework.

RESULTS

A total of 3517 articles were identified in the searches, and 28 were included in the final review after assessment by two independent reviewers. Two generic instruments (SF-36 and Sickness Impact Profile) and nine condition-specific PROMs were identified.

CONCLUSIONS

Overall, there is a limited volume of published evidence for the application of generic PROMs for people with skin cancer. Evaluation of the EQ-5D may be particularly important given its widespread use in many other healthcare contexts in the U.K. The Skin Cancer Index could be considered for piloting in the NHS. For patients with nonmelanoma skin cancers, the Skindex measures may also be considered. The SCQOLIT has some evidence of applicability across both skin cancer types but more evaluations are needed. The FACT-M does have more promising characteristics for patients with malignant melanomas although no evidence of testing in the U.K. was found. The forthcoming EORTC-M may prove a useful measure given the expertise and track record of this European collaboration in cancer and quality of life.

Barriers and facilitators of adherence to medical advice on skin self-examination during melanoma follow-up care

BACKGROUND

Melanoma is the fastest growing tumor of the skin, which disproportionately affects younger and middle-aged adults. As melanomas are visible, recognizable, and highly curable while in early stages, early diagnosis is one of the most effective measures to decrease melanoma-related mortality. Skin self-examination results in earlier detection and removal of the melanoma. Due to the elevated risk of survivors for developing subsequent melanomas, monthly self-exams are strongly recommended as part of follow-up care. Yet, only a minority of high-risk individuals practices systematic and regular self-exams. This can be improved through patient education. However, dermatological education is effective only in about 50% of the cases and little is known about those who do not respond. In the current literature, psychosocial variables like distress, coping with cancer, as well as partner and physician support are widely neglected in relation to the practice of skin self-examination, despite the fact that they have been shown to be essential for other health behaviors and for adherence to medical advice. Moreover, the current body of knowledge is compromised by the inconsistent conceptualization of SSE. The main objective of the current project is to examine psychosocial predictors of skin self-examination using on a rigorous and clinically sound methodology.

METHODS/DESIGN

The longitudinal, mixed-method study examines key psychosocial variables related to the acquisition and to the long-term maintenance of skin self-examination in 200 patients with melanoma. Practice of self-exam behaviors is assessed at 3 and 12 months after receiving an educational intervention designed based on best-practice standards. Examined predictors of skin self-exam behaviors include biological sex, perceived self-exam efficacy, distress, partner and physician support, and coping strategies. Qualitative analyses of semi-structured interviews will complement and enlighten the quantitative findings.

DISCUSSION

The identification of short and long-term predictors of skin self-examination and an increased understanding of barriers will allow health care professionals to better address patient difficulties in adhering to this life-saving health behavior. Furthermore, the findings will enable the development and evaluation of evidence-based, comprehensive intervention strategies. Ultimately, these findings could impact a wide range of outreach programs and secondary prevention initiatives for other populations with increased melanoma risk.

Skin reactions and quality of life after x-ray therapy of Basal cell carcinoma

Background. Advanced basal cell carcinoma (BCC) is often treated by surgery or X-ray therapy. The consequences of X-ray therapy on the patients' health-related quality-of-life (HRQOL) have so far not been described. Objectives. To quantify quality of life in BCC patients before and after X-ray therapy compared with matched healthy controls. Materials. Twenty-five patients (mean age 69) with BCC completed the Dermatology Life Quality Index (DLQI) before and two weeks and three months after X-ray therapy and their results were compared with the DLQI scores for 25 matched controls. Results. Compared to the healthy controls the patients' DLQI score was significantly higher before and 2 weeks after X-ray therapy (P = 0.005; P = 0.000). The patients' DLQI score decreased significantly from baseline to three months after X-ray therapy (P = 0.024), when it became similar to that of the healthy controls (P = 0.819). Three months after X-ray therapy eight patients had no skin reactions, 11 had slight atrophy, pigmentation change, and/or some hair loss, four had patch atrophy, moderate telangiectasia, and/or total hair loss. Conclusions. BCC has a negative effect on patients' quality of life. The study shows that HRQOL normalises shortly after X-ray therapy, despite minor skin manifestations.

Factors associated with large cutaneous squamous cell carcinomas

BACKGROUND

Large cutaneous squamous cell carcinoma (SCC) is associated with a higher risk of disfigurement, local recurrence, and metastasis; however, little is known about factors associated with tumor size at diagnosis.

OBJECTIVES

We sought to evaluate factors associated with SCC size, including diagnostic/treatment delay and patient and tumor characteristics.

METHODS

We studied a stratified sample of 308 patients with SCC recently treated at a dermatologic referral center in Italy. Medical records were reviewed and telephone interviews conducted. Multiple logistic regression was used to examine factors associated with SCC size.

RESULTS

With univariate analyses, among both invasive and in situ cases, SCC greater than 2 cm was significantly associated with male gender, tumors arising in chronic lesions, and tumors located on not easily visible sites. Long delay before surgical removal was significantly associated with large SCC size only for invasive SCC (P < .001). Among patients with invasive SCC, when controlling for age and gender, multivariate analysis showed a significantly higher likelihood of SCC greater than 2 cm with a total delay longer than 18 months before surgical removal (odds ratio=4.18; 95% confidence interval 2.45-7.13) and for tumors arising in chronic lesions (odds ratio=6.42; 95% confidence interval 3.13-13.2).

LIMITATIONS

The study was cross-sectional and based on a single center.

CONCLUSIONS

Long total delay in removal significantly increased the likelihood of invasive SCC greater than 2 cm. Our findings highlight the importance of early detection and treatment to prevent large invasive SCCs, which are associated with a higher risk of disfigurement, recurrence, and metastasis. Particular attention should be paid to chronic skin lesions and not easily visible body sites during physician- and patient-performed examinations.

The skin cancer index: clinical responsiveness and predictors of quality of life

OBJECTIVE

To establish the clinical responsiveness of the Skin Cancer Index (SCI), a new disease-specific quality of life (QOL) instrument, and to assess demographic and clinical factors which impact QOL in patients with nonmelanoma skin cancer (NMSC).

STUDY DESIGN

Prospective study of 183 patients with NMSC of the face and neck referred to a tertiary care Mohs surgery clinic.

METHODS

The SCI is a 15 item, validated, disease-specific QOL instrument with 3 distinct subscales, Emotion, Social, and Appearance. Higher scores reflect better QOL. The SCI and the Dermatology Life Quality Index (DLQI), a general dermatology instrument, was administered at initial consultation and 4 months after surgical treatment. Multivariate analysis was conducted to assess demographic and clinical factors predictive of QOL for both instruments.

RESULTS

The SCI total score and all three subscale scores increased with treatment, demonstrating strong evidence of responsiveness over time (P < .001) in contrast with the DLQI (P = .46). Predictors of poorer QOL for the SCI included female sex and cancers located on the lip. Patients who demonstrated greatest improvement in QOL with treatment included those who were younger (<50 yr) and had lower reported household income. Also, first time NMSC patients and those patients who underwent less extensive reconstructions demonstrated greater improvements in QOL.

CONCLUSION

The SCI is a sensitive and responsive QOL instrument for patients with NMSC. Distinct demographic and clinical variables that impact QOL have been demonstrated using this multidimensional, disease-specific instrument.

Validation of a quality-of-life instrument for patients with nonmelanoma skin cancer

OBJECTIVE

To validate a disease-specific quality-of-life instrument--the Skin Cancer Index--intended to measure quality-of-life issues relevant to patients with nonmelanoma skin cancer.

METHODS

Internal reliability, convergent and divergent validity with existing scales, and factor analyses were performed in a cross-sectional study of 211 patients presenting with cervicofacial nonmelanoma skin cancer to a dermatologic surgery clinic.

RESULTS

Factor analyses of the Skin Cancer Index confirmed a multidimensional scale with 3 distinct subscales-emotional, social, and appearance. Excellent internal validity of the 3 subscales was demonstrated. Substantial evidence was observed for convergent validity with the Dermatology Life Quality Index, Rosenberg Self-Esteem Scale, Lerman's Cancer Worry Scale, and Medical Outcomes Survey Short-Form 12 domains for vitality, emotion, social function, and mental health.

CONCLUSIONS

These findings validate a new disease-specific quality-of-life instrument for patients with cervicofacial nonmelanoma skin cancer. Studies on the responsiveness of the Skin Cancer Index to clinical intervention are currently under way.
