Mortality and morbidity after initial diagnostic excision biopsy of cutaneous melanoma in primary versus secondary care

Measuring the quality of skin cancer management in primary care: A scoping review

Skin cancer is a growing global problem and a significant health and economic burden. Despite the practical necessity for skin cancer to be managed in primary care settings, little is known about how quality of care is or should be measured in this setting. This scoping review aimed to capture the breadth and range of contemporary evidence related to the measurement of quality in skin cancer management in primary care settings. Six databases were searched for relevant texts reporting on quality measurement in primary care skin cancer management. Data from 46 texts published since 2011 were extracted, and quality measures were catalogued according to the three domains of the Donabedian model of healthcare quality (structure, process and outcome). Quality measures within each domain were inductively analysed into 13 key emergent groups. These represented what were deemed to be the most relevant components of skin cancer management as related to structure, process or outcomes measurement. Four groups related to the structural elements of care provision (e.g. diagnostic tools and equipment), five related to the process of care delivery (e.g. diagnostic processes) and four related to the outcomes of care (e.g. poor treatment outcomes). A broad range of quality measures have been documented, based predominantly on articles using retrospective cohort designs; systematic reviews and randomised controlled trials were limited.

Diagnostic biopsy of cutaneous melanoma, sentinel lymph node biopsy and indications for lymphadenectomy

The incidence of cutaneous melanoma appears to be increasing worldwide and this is attributed to solar radiation exposure. Early diagnosis is a challenging task. Any clinically suspected lesion must be assessed by complete diagnostic excision biopsy (margins 1-2 mm); however, there are other biopsy techniques that are less commonly used. Melanomas are characterized by Breslow thickness as thin (< 1 mm), intermediate (1-4 mm) and thick (> 4 mm). This thickness determines their biological behavior, therapy, prognosis and survival. If the biopsy is positive, a wide local excision (margins 1-2 cm) is finally performed. However, metastasis to regional lymph nodes is the most accurate prognostic determinant. Therefore, sentinel lymph node biopsy (SLNB) for diagnosed melanoma plays a pivotal role in the management strategy. Complete lymph node clearance has undoubted advantages and is recommended in all cases of positive SLN biopsy. A PET-CT (positron emission tomography-computed tomography) scan is necessary for staging and follow-up after treatment. Novel targeted therapies and immunotherapies have shown improved outcomes in advanced cases.

Management of Melanoma Patients by Non-Dermatologists in the Military Health System: A Retrospective Observational Study

INTRODUCTION

Compared to their civilian counterparts, military personnel can have more exposure to sunlight and, as recent studies have shown, do have an increased incidence of melanoma. Given the inherent challenges service members may face in getting appropriate care whether because of operational tempo, deployments, and/or austere locations, many are initially diagnosed by specialties other than dermatology. In this study, we sought to determine if patients within the military health system were receiving appropriate follow-up management after biopsies by non-dermatologists led to the diagnosis of melanoma by pathology.

MATERIALS AND METHODS

Using the Co-Path system, 1,000 patients were identified who had first time biopsies positive for melanoma. Of these, 73 were originally biopsied by non-dermatologists. Retrospective medical record review was performed to determine specialties of the non-dermatologists, staging of melanoma at diagnosis, referrals to specialists and dermatologists, and adherence to National Comprehensive Cancer Network guidelines. The study protocol was approved by the Walter Reed National Military Medical Center Institutional Review Board, protocol number WRNMMC-EDO-2017-0030, in compliance with all applicable federal regulations governing the protection of human subject research.

RESULTS

Family medicine physicians made up the majority of non-dermatologists involved in performing biopsies that led to the diagnosis of melanoma in this study. Most patients were Stage I (pT1a), and the average time from initial biopsy to further wide excision biopsy was 18 days. Sixty-seven of the 73 patients biopsied by non-dermatologists received referrals to dermatologists, and 55 of the 67 patients followed through with being seen. Follow-up full body skin exams were performed on 55 of the 73 patients, with dermatologists conducting the majority of them. National Comprehensive Cancer Network guidelines were followed in 45 of the 73 patients, with an additional 24 patients having insufficient evidence to determine if guidelines were adhered to.

CONCLUSION

Our study demonstrated that a number of different specialties outside of dermatology are involved in performing biopsies on patients in which melanoma is a concern. Although the results show that the majority of patients biopsied by non-dermatologists received appropriate follow-up care, there is still room to improve to ensure that all melanoma patients receive referrals to and are seen by dermatologists after a diagnosis of melanoma.

Impact of rurality on processes and outcomes in melanoma care: results from a whole-Scotland melanoma cohort in primary and secondary care

BACKGROUND

Those living in rural areas have poorer cancer outcomes, but current evidence on how rurality impacts melanoma care and survival is contradictory.

AIM

To investigate the impact of rurality on setting of melanoma excision and mortality in a whole-nation cohort.

DESIGN AND SETTING

Analysis of linked routine healthcare data comprising every individual in Scotland diagnosed with melanoma, January 2005-December 2013, in primary and secondary care.

METHOD

Multivariate binary logistic regression was used to explore the relationship between rurality and setting of melanoma excision; Cox proportional hazards regression between rurality and mortality was used, with adjustments for key confounders.

RESULTS

In total 9519 patients were included (54.3% [n = 5167] female, mean age 60.2 years [SD 17.5]). Of melanomas where setting of excision was known, 90.3% (n = 8598) were in secondary care and 8.1% (n = 771) in primary care. Odds of primary care excision increased with increasing rurality/remoteness. Compared with those in urban areas, those in the most remote rural locations had almost twice the odds of melanoma excision in primary care (adjusted odds ratio [aOR] 1.92; 95% confidence interval [CI] = 1.33 to 2.77). No significant association was found between urban or rural residency and all-cause mortality. Melanoma-specific mortality was significantly lower in individuals residing in accessible small towns than in large urban areas (adjusted hazards ratio [HR] 0.53; 95% CI = 0.33 to 0.87) with no trend towards poorer survival with increasing rurality.

CONCLUSION

Patients in Scottish rural locations were more likely to have a melanoma excised in primary care. However, those in rural areas did not have significantly increased mortality from melanoma. Together these findings suggest that current UK melanoma management guidelines could be revised to be more realistic by recognising the role of primary care in the prompt diagnosis and treatment of those in rural locations.

Improving early diagnosis of symptomatic cancer

Much time, effort and investment goes into the diagnosis of symptomatic cancer, with the expectation that this approach brings clinical benefits. This investment of resources has been particularly noticeable in the UK, which has, for several years, appeared near the bottom of international league tables for cancer survival in economically developed countries. In this Review, we examine expedited diagnosis of cancer from four perspectives. The first relates to the potential for clinical benefits of expedited diagnosis of symptomatic cancer. Limited evidence from clinical trials is available, but the considerable observational evidence suggests benefits can be obtained from this approach. The second perspective considers how expedited diagnosis can be achieved. We concentrate on data from the UK, where extensive awareness campaigns have been conducted, and initiatives in the primary-care setting, including clinical decision support, have all occurred during a period of considerable national policy change. The third section considers the most appropriate patients for cancer investigations, and the possible community settings for identification of such patients; UK national guidance for selection of patients for investigation is discussed. Finally, the health economics of expedited diagnosis are reviewed, although few studies provide definitive evidence on this topic.

Comparing initial diagnostic excision biopsy of cutaneous malignant melanoma in primary versus secondary care: A study of Irish National data

BACKGROUND

The incidence of melanoma is rising worldwide. Current Irish guidelines from the National Cancer Control Programme state suspicious pigmented lesions should not be removed in primary care. There are conflicting guidelines and research advising who should remove possible melanomas.

OBJECTIVES

To determine whether initial diagnostic excision biopsy of cutaneous malignant melanoma in primary versus secondary care leads to poorer survival.

METHODS

Analysis of data comprising 7116 cases of cutaneous malignant melanoma from the National Cancer Registry Ireland between January 2002 and December 2011. Single predictor variables were examined by the chi-square or Mann-Whitney U test. The effects of single predictor variables on survival were examined by Cox proportionate hazards modelling and a multivariate Cox model of survival based on excision in a non-hospital setting versus hospital setting was derived with adjusted and unadjusted hazard ratios.

RESULTS

Over a 10-year period 8.5% of melanomas in Ireland were removed in a non-hospital setting. When comparing melanoma death between the hospital and non-hospital groups, the adjusted hazard ratio was 1.56 (95%CI: 1.08-2.26); (P = .02), indicating a non-inferior outcome for the melanoma cases initially treated in the non-hospital group, after adjustment for significant covariates.

CONCLUSION

This study suggests that initial excision biopsy carried out in general practice does not lead to a poorer outcome. [Box: see text].

Teledermatology-directed surgical care is safe and reduces travel

METHODS

We conducted a retrospective chart review and identified 186 Veterans in the VA Corporate Data Warehouse as having malignant melanomas or severely dysplastic nevi during the four-year period of observation from 1 July 2009 to 30 June 2013 and met inclusion and exclusion criteria for analysis.

RESULTS

Three hundred and sixty-six surgical procedures were performed for diagnosis and treatment of these conditions including biopsy and wide-local excision, of which 189 carefully selected cases were performed by primary care clinicians with 2.0% biopsy complication rate and a 7.7% wide-local excision complication rate. Cases not performed by primary care providers were referred to specialists (e.g. dermatologists, general surgeons or specialty surgeons) who had a 2.5% complication rate in biopsies and wide-local excision complication rate of 13.5% in severely dysplastic nevi and pTis and pT1a lesions and a 10.7% complication rate for lesions pT1b and greater.

DISCUSSION

These results show that a significant fraction of surgical procedures for diagnosis and treatment of malignant melanoma and severely dysplastic nevi can be safely performed in rural clinics by trained primary care providers.
