Operationalization of skin self-examination in randomized controlled trials with individuals at increased risk for melanoma: A systematic review. PATIENT EDUCATION AND COUNSELING 2020; 103:1013-1026. [PMID: 31917011 DOI: 10.1016/j.pec.2019.12.009] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/09/2019] [Revised: 11/25/2019] [Accepted: 12/11/2019] [Indexed: 06/10/2023]
Abstract
OBJECTIVE To investigate how skin self-examination was operationalized and the psychometric properties of the scales used to assess this behavior in randomized controlled trials (RCTs) testing interventions that promote SSE among individuals at increased risk for melanoma. METHOD Eight scientific databases (e.g., Medline, EMBASE, CINAHL, PsycINFO) and four trial registries (e.g., Clinicaltrials.gov, UK Clinical Trails Gateway) were searched from inception through April 2, 2019. Three reviewers carried out the selection of relevant trials and conducted data extraction. RESULTS The review identified 13 unique RCT's. The definition of skin self-exams, extrapolated from instructions provided to participants during the trials and reported in only 6/13 trials, included periodically checking the skin of the entire body, individually or with partners/mirrors, with or without tracking or monitoring tools, and using the ABCDE criteria to identify early signs of melanoma. There was variability in how skin self-examination behavior was measured with respect to item content, number of items, response format, and type of outcome variable used: continuous or binary). No validity evidence and minimal reliability evidence for the measures were identified. CONCLUSIONS AND PRACTICE IMPLICATIONS Future studies are needed to establish the psychometric properties of measures assessing skin self-examination.

Short and long-term barriers and facilitators of skin self-examination among individuals diagnosed with melanoma. BMC Cancer 2020; 20:123. [PMID: 32059700 PMCID: PMC7023754 DOI: 10.1186/s12885-019-6476-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2019] [Accepted: 12/17/2019] [Indexed: 12/21/2022] Open
Abstract
Background Melanoma can be lethal if not detected early and treated. Early detection can be facilitated via skin self-examination (SSE) and as such, SSE is part of melanoma follow-up care for individuals with a prior history, who face a life-long risk of reoccurrence. The objective of the current study was to identify short- and long-term predictors of SSE among melanoma survivors to inform future prevention interventions in high-risk groups. Method This is an observational study with longitudinal assessments conducted with adult melanoma patients in active follow-up care. Primary outcome measures Behavioral outcomes, comprehensive SSE (checking up to 5 body areas in the last 3 months) and optimal SSE (checking the entire body at least monthly in the last 3 months) were assessed at 3, 12, and 24 months post a dermatological educational session on skin cancer prevention. T tests and chi square analyses were used to examine changes in outcomes from 3 to 12 and 24 months. Linear and logistic regression models were used to examine the association between predictors and the primary outcomes. Results Comprehensive SSE did not decrease significantly from 3 (M = 2.7, SD = 1.1) to 12 (M = 2.6, SD = 1.2) and 24 months (M = 2.4, SD = 1.2) post the education session, with the stronger predictor at all timepoints being intentions to perform SSE. Optimal SSE was higher at 3 months (59%) compared to 12 (46%) and 24 months (34%), with key predictors including self-efficacy and intentions to perform SSE and male sex at 3 months post; self-efficacy and reliance on medical advice at 12 months; and (lower) education and self-efficacy at 24 months. Conclusions The key findings of this study are that 1) survivors maintain SSE behaviour over time, but rates of SSE performed in agreement with medical recommendations are higher immediately post standard dermatological education (i.e. usual care) and decrease somewhat over a 24-month period; and 2) the strongest psycho-social predictors of SSE are intentions and self-efficacy to perform the behavior, which are highly modifiable, for example via motivational interviewing and goal setting health interventions.

Abstract
OBJECTIVE To provide a formal statistical comparison of the efficacy of melanoma detection among different clinical settings. METHODS A systematic review and meta-analysis of all relevant observational studies on number needed to treat (NNT) in relation to melanoma was performed in MEDLINE. We performed a random-effects model meta-analysis and reported NNTs with 95% confidence intervals (CIs). The subgroup analysis was related to clinical setting. RESULTS In all, 29 articles including a total of 398,549 biopsies/excisions were analyzed. The overall NNT was 9.71 (95% CI, 7.72-12.29): 22.62 (95% CI, 12.95-40.10) for primary care, 9.60 (95% CI, 6.97-13.41) for dermatology, and 5.85 (95% CI, 4.24-8.27) for pigmented lesion specialists. LIMITATIONS There is heterogeneity in data reporting and the possibility of missing studies. In addition, the incidence of melanoma varies among clinical settings, which could affect NNT calculations. CONCLUSION Pigmented lesion specialists have the lowest NNT, followed by dermatologists, suggesting that involving specialists in the diagnosis and treatment of pigmented skin lesions can likely improve patient outcomes.

Abstract
Importance To date, no concerted effort has been made to date to evaluate the literature on number-needed-to-biopsy (NNB) metrics, particularly to account for the differences in clinician type and melanoma prevalence in certain geographic locations. Objective To review and synthesize worldwide data for NNB for the diagnosis of cutaneous melanoma. Data Source MEDLINE, Embase, and PubMed databases were searched for English-language articles published worldwide from January 1, 2000, to November 28, 2018. Study Selection A total of 46 studies were included that addressed NNB for at least 3681 clinicians worldwide and included 455 496 biopsied tumors and 29 257 melanomas; primary care practitioner (PCP) data were only available from Australia. Data Extraction and Synthesis Articles were screened for eligibility, and possible overlapping data sets were resolved. Data extracted included clinician specialization, use of dermoscopy, geographic region and location-specific health care system, study design, number of benign tumors, number of melanomas, and NNB. The review followed the PRISMA guidelines. Main Outcome and Measures The NNB for the diagnosis of cutaneous melanoma. Results A total of 46 studies were included that addressed NNB for at least 3681 clinicians worldwide and included 455 496 biopsied tumors and 29 257 melanomas; primary care practitioner (PCP) data were only available from Australia. The reported NNB ranged from 2.2 to 287, and the weighted mean NNB for all included publications was 15.6. The exclusion of publications structured as all biopsied tumors, owing to variable data characterization, resulted in reported NNB ranging from 2.2 to 30.5, with a global weighted mean NNB of 14.8 for all clinicians, 7.5 for all dermatologists, 14.6 for Australian PCPs, and 13.2 for all US-based dermatological practitioners, including dermatologists and advanced practice professionals. The summary effect size (ES) demonstrates that a mean 4% of biopsies demonstrated melanoma for study stratum A (all biopsied skin tumors, ES, 0.04; 95% CI, 0.03-0.05), and a mean 12% of biopsies demonstrated melanoma for study strata B (melanocytic tumors on pathology review, ES, 0.12; 95% CI, 0.10-0.14) and C (clinical concern for melanoma, ES; 0.12; 95% CI, 0.09-0.14). Conclusions and Relevance The existing NNB for cutaneous melanoma appeared to vary widely worldwide, lacking standardization in the metric and its reporting, and according to clinician characteristics as well; the NNB of US-based clinicians may warrant further exploration.

Abstract
There is a growing concern and awareness of skin cancer. As a result, possibly unnecessary surgeries of melanocytic lesions are carried out as a prophylactic measure. We performed a systematic review of the medical literature to identify primary studies on the effectiveness and cost-effectiveness of surgery treatment of benign melanocytic lesions for melanoma prevention. We included 19 primary studies on surgical treatment of acquired melanocytic lesions and one economic evaluation. Indicators, such as number needed to treat and the malignancy ratio, depend on several factors such as specialty and experience of the physician, pressure from the patient or patient characteristics. Early diagnosis of melanoma is critical in preventing skin cancer. However, primary studies show through several indicators that there are factors that increase the proportion of lesions treated unnecessarily. Effectiveness can be improved by careful use of techniques to identify suspicious lesions and educational programs for physicians, especially in primary care.

Abstract
BACKGROUND Cytomorphological assessment of erosive skin tumours offers a rapid and minimally invasive way to obtain a diagnosis. However, the studies so far conducted on this method have been relatively small. AIM To conduct a large retrospective study on cytomorphological assessment of erosive skin tumours. METHODS In this study, 86 cytological smears prepared from erosive cutaneous tumours clinically suspicious for melanoma were examined to test the diagnostic accuracy and practicability of cytomorphological evaluation of such tumours, and to compare the assessments of two investigators with different experience levels. In a subgroup of tumours, cytological assessment was compared with dermoscopic evaluation. RESULTS There was agreement in the cytological and histopathological results for 68 of 86 cases (79%) assessed by the experienced investigator and in 64 of 86 cases (74%) assessed by the inexperienced investigator. The diagnosis was confirmed cytologically in 39 and 34 of 42 melanomas, and in 28 and 27 of 35 basal cell carcinomas, respectively. The sensitivity of the cytodiagnosis was not significantly different between the two investigators. The dermoscopic evaluation showed good agreement with the cytological results for melanoma (82.4%), although use of dermoscopy was only possible for 49.9% of the lesions because of difficulties with the samples. CONCLUSIONS Cytological assessment of erosive melanoma and BCC lesions is a useful tool for gaining additional information on clinically uncertain skin tumours, and shows good agreement between different investigators.

Abstract
BACKGROUND AND OBJECTIVE The incidence and mortality from melanoma continue to rise worldwide. Unfortunately, there is still no consistently effective treatment for metastatic disease. The fact that survival for melanoma has increased dramatically over the last 30 years highlights the importance of early detection of this malignancy. CONCLUSION With continued public education and the advent of new technologies, it is hoped that we will be able to improve on what has been accomplished to date to reduce the health burden of melanoma even further. This article reviews issues related to patient and physician detection of melanoma and highlights newer technologies being used for this purpose.

Abstract
Recognizing early forms of melanoma may have significant impact on decreasing mortality from this malignancy. As a result, multiple efforts have focused on developing new and improving current early detection strategies. These include educating patients about the importance of performing skin self-examination, increasing rates of complete skin examinations by physicians in the context of routine care, initiating mass screening campaigns, creating specialized skin cancer clinics, and developing better diagnostic tools through advances in technology. In this article, the current state of these efforts is reviewed.

Abstract
To better understand the clinical diagnostic process for invasive melanoma in Queensland. Descriptive population-based study of Queensland residents (n=3772) aged 20-75 years diagnosed with invasive melanoma between January 2000 and December 2003. Information was obtained via telephone interview combined with pathology data from the Queensland Cancer Registry. About 85% of melanoma patients diagnosed in Queensland saw a general practitioner at least once during the process, most of these for the initial consultation. Almost one-fifth of patients (18.1%) saw a skin clinic doctor sometime through the diagnosis pathway; this proportion increased significantly over the study period (P<0.001). The most common pathway for diagnosing melanoma was an initial consultation by a general practitioner followed by referral to a surgeon for a definitive diagnosis. People living in southeast Queensland were more likely to see a dermatologist compared with those living in more rural or remote areas (14.7 versus 6.8%), more likely to see a skin clinic doctor (21.8 versus 7.2%), or a surgeon (54.9 versus 49.3%) at least once during the diagnostic process, and less likely to see a general practitioner (76.8 versus 90.2%). This descriptive study has demonstrated the complexity and diversity of clinical diagnostic pathways for melanoma in Queensland, highlighting the important role of general practitioners and the emerging role of primary care skin clinics. Although this system has resulted in a very favourable thickness distribution for diagnosed melanomas, access issues for people living in rural and remote areas of Queensland need to be addressed.

Abstract
BACKGROUND Skin self-examination (SSE) is associated with thinner melanomas in both North American and Italian patients. The knowledge of conditions associated with SSE may help in refining educational strategies for the prevention of melanoma. OBJECTIVE The aim of the study was to investigate the frequency of SSE and the factors associated with SSE in subjects followed at a specialized pigmented lesion clinic (PLC) in Italy. PATIENTS/METHODS A series of 299 consecutive subjects who visited the Florence PLC was investigated by means of a self-administered questionnaire regarding SSE habits. The statistical association between SSE and selected variables was examined by univariate and multivariate analyses. RESULTS In the univariate analysis, variables significantly associated with SSE were: green/blue eyes, phototype I/II, the presence of large numbers of common acquired and atypical melanocytic naevi, sunscreen use, having had a previous PLC examination, and having received a leaflet explaining SSE. SSE was less frequent in women using sunbeds and more frequent in those performing breast self-examination. Using the multivariate model, which included all the variables associated with SSE in the previous analysis, we found that, among males, the only variable significantly associated with SSE was the report of having received a leaflet explaining SSE [odds ratio (OR) 3.02, 95% confidence interval (CI) 1.24-7.38]. Among females, having had a previous consultation at a PLC was significantly associated with SSE (OR 4.84, 95%CI 1.57-14.93); this might be because of the explanation and advice about skin cancer prevention customarily provided as a part of the PLC consultation at our department. CONCLUSION Educational tools, including a leaflet explaining SSE and counselling given within previous PLC visits, seem to play a crucial role in promoting SSE habits in subjects followed at a specialized PLC consultation.

Abstract
BACKGROUND Guidelines for optimized use of digital follow-up of melanocytic lesions are not yet available, and little is known about inclusion criteria adopted in clinical practice. OBJECTIVE Our purpose was to describe the frequency of digital follow-up adoption in melanoma screening, the characteristics of patients and lesions selected, and the predictors of duration of the intervals of digital follow-up. METHODS Baseline characteristics of patients and lesions selected for digital follow-up in 12 Italian pigmented lesion clinics were examined. Predictors of a short follow-up interval (<or=3 months) compared with a 6-month interval were investigated by means of logistic regression analysis. RESULTS Out of 2116 subjects consecutively examined, 409 were submitted to digital follow-up (19.3%), with 1.6 mean lesions found per patient (range, 1-9; median, 1). According to an a posteriori analysis, 15.2% of the lesions were diagnostically equivocal and 7.8% of lesions had a total dermoscopy score (TDS) suggestive of malignancy. However, large differences in the TDS were found among the participating centers. Determinants of a short follow-up interval, adopted in 40.8% of patients, were the personal history of melanoma (odds ratio [OR] 2.56, 95% confidence interval [CI] 1.09-5.99) and the presence of atypical nevi (at least one atypical nevus (OR 4.54, 95% CI 2.45-8.42). Unexpectedly, the dermoscopic atypia of the lesion (TDS >4.75) was associated only with a marginal effect on the scheduled duration of follow-up interval (OR 1.34, 95% CI 0.97-1.86). These findings were confirmed by a multivariate analysis. LIMITATIONS The adoption of different digital dermoscopy systems in the participating centers may have limited the reliability of the TDS assigned by a central group to dermoscopy images. CONCLUSIONS Practicing dermatologists who use digital epiluminescence microscopy in screening for melanoma decided to submit at least one melanocytic lesion to digital follow-up for approximately 1 patient for every 5 examined. This implies costs and time spent that need to be evaluated together with the benefits of this procedure from a large-scale perspective. The lack of well-defined guidelines for inclusion and exclusion criteria may hamper optimized use of digital follow-up in daily practice.

Abstract
BACKGROUND Melanoma is an important cause of morbidity and mortality. Recently published Scottish Intercollegiate Guideline Network (SIGN) guidelines outline standard management for melanoma patients in Scotland. METHODS We audited the management of consecutive patients diagnosed with melanoma in Glasgow Royal Infirmary (1998-2003), using the SIGN guidelines as a gold standard. RESULTS Of 102 patients, 41% were male and 59% were female. The mean ages of men and women were 58 and 50 years respectively. Fifty five per cent of all patients had a superficial spreading melanoma, and the median Breslow thickness was 0.64 mm. The most commonly affected site was the head and neck (29%). Most patients (87%) were referred by their general practitioner, but only 30% were marked as urgent by the referrer, and accordingly the median time to first appointment varied between 20 days (1998) and 52 days (2001). The most frequently noted suspicious feature was irregular pigmentation. The median time to biopsy was 6 days. Seventy-one per cent of patients had an excision biopsy, and of those who did not, most (71%) had lesions on the head and neck. There was poor recording of surgical margins (13%) and histological margins were used to determine the need for re-excision. The SIGN guidelines for re-excision and sentinel lymph node biopsy were closely followed. CONCLUSION The SIGN guidelines for melanoma have been adhered to in our department, although time to first appointment exceeded national recommendations.

Abstract
To ensure the removal of all melanomas at an early phase, a number of benign lesions are currently excised for diagnostic evaluation. Nevertheless, little is known about the frequency of melanomas missed (neither recognized nor excised for diagnostic verification) by early detection practices. This study aimed to investigate the diagnostic performance of a specialized pigmented lesion clinic (PLC) through linkage with a local cancer registry. In 1997, 1741 individuals resident in the area of Florence and Prato, Italy, the catchment area of the Tuscany Cancer Registry (RTT), were consecutively examined at a specialized PLC that has been running since 1992 at the Department of Dermatology of Florence. The outcomes of dermatological consultations retrieved from PLC case notes were compared with all the diagnoses of both in situ and invasive melanoma recorded by the RTT until 31 December 1999. The performance of the PLC in detecting cutaneous melanoma was evaluated in terms of sensitivity, specificity and predictive values, with the RTT data as the gold standard. In the population examined at the PLC, 15 newly incident melanomas, all histologically demonstrated, were recorded by the RTT. In 13 of the 15 cases, excision of the lesion had been recommended by PLC staff, while two melanomas, one in situ and one level II 0.60 mm thick invasive, were missed and were subsequently excised 586 and 824 days, respectively, after the first PLC examination. The clinical and dermoscopic features of the invasive lesion were in agreement with a 'featureless' melanoma, and lacked the well-established parameters of malignancy. A total of 67 benign pigmented skin lesions were excised for diagnostic evaluation. Thus the PLC showed a sensitivity in detecting cutaneous melanoma of 86.7% (95% confidence interval [CI] 85.1-88.3%), a specificity of 95.4% (95% CI 94.3-96.3%), a positive predictive value of 13.7% (95% CI 12.1-15.3%) and a negative predictive value of 99.9% (95% CI 99.7-100.0%). The ratio of melanomas to benign skin lesions excised was 1:5.1. In conclusion, specialized examination of pigmented skin lesions at the PLC offered good level of diagnostic performance, with an acceptable cost in terms of benign lesions removed and overall a low risk of missing melanomas.

Abstract
Little is known about ability of family doctors in the diagnosis and management (decision as to dermatologic referral) of pigmented skin lesions. We sought to evaluate the impact of a short formal training on diagnostic and referral accuracy of family doctors in melanoma screening. A formal 4-h training session was given to a sample of 41 practising family doctors working in the Florence health district, Tuscany, Italy. Before and after the course, a diagnostic test with a series of clinical images of pigmented skin lesions including four invasive melanomas (mean thickness, 1.5 mm; range, 0.8-2.2) was performed (open intervention study). Although only 46.8% of observations yielded a correct melanoma diagnosis at baseline, 96.1% of melanoma observations were correctly associated with intention to refer the lesion to dermatologist. After training, the percentage of correct melanoma diagnosis significantly increased (76.2%, P=0.01) while no further improvement was found as to sensitivity of referral (94.8%, P=0.58). Compared to baseline, post-training evaluation showed a significant reduction of benign lesions sent to dermatologist: the percentage lowered from 52.1 to 35.8% (P=0.0014) for melanocytic nevi and from 38.6 to 17.5% (P<0.001) for benign non-melanocytic lesions (pigmented seborrheic keratoses, dermatofibromas, and vascular lesions). Grouping these two diagnostic categories, the overall specificity in dermatology referral increased from 55.0% at baseline to 73.1% after training (P<0.001). In conclusion, attendance at a 4-h formal training session was able to increase the specificity of family doctors as to dermatologist referral of suspicious lesions (less false-positive referral of benign lesions) without significant loss in sensitivity concerning melanoma.

Abstract
OBJECTIVE We sought to assess the difference in lesion management between combined examination (naked-eye and dermoscopy) and conventional naked-eye examination in evaluations for melanoma; and to assess the impact on patient treatment of facilities for digital follow-up of diagnostically equivocal lesions. METHODS We conducted a randomized, controlled trial at a pigmented lesion clinic in a university hospital. A total of 938 consecutive subjects presenting between November 1, 2001, and March 31, 2002, were eligible and 25 were excluded because they were younger than 12 years of age; hence 913 subjects were enrolled. Participants were randomized to combined examination with mandatory excision of equivocal lesion (arm B) and with possibility of digital follow-up according to the clinician's decision (arm C), or to conventional naked-eye examination (mandatory excision of equivocal lesion) (arm A). The same pigmented lesion clinic staff examined all subjects. RESULTS Combined examination determined a significant reduction in the percentage of patients referred for operation (9.0% vs 15.6%) (P =.013). When facilities for digital follow-up of equivocal lesions were available, the percentage of patients classified as harboring lesions difficult to diagnose increased (group C, 35.8%; group B, 17.8%; P <.01). About half of them were immediately referred for operation whereas the remainder submitted to second examination (digital follow-up). Two melanomas (1 in situ and 1 invasive, 0.40-mm thick) were diagnosed after second examination performed 6 months later. The number of melanomas eventually excised within the study were similar among the 3 allocation groups (3, 2, and 3, respectively). CONCLUSIONS the addition of dermoscopy to conventional naked-eye examination is associated with a significant reduction of number of pigmented skin lesions excised for diagnostic verification. The possibility of digital follow-up of equivocal lesions is associated with a not negligible occurrence of initial melanomas left unexcised until the second consultation.
