Environmental Exposures Such as Smoking and Low Vitamin D Are Predictive of Poor Outcome in Cutaneous Melanoma rather than Other Deprivation Measures. J Invest Dermatol 2020; 140:327-337.e2. [PMID: 31425707 PMCID: PMC6983339 DOI: 10.1016/j.jid.2019.05.033] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2018] [Revised: 05/06/2019] [Accepted: 05/08/2019] [Indexed: 01/17/2023]
Abstract
A lack of basic resources within a society (deprivation) is associated with increased cancer mortality, and this relationship has been described for melanoma. We have previously reported the association of smoking and low vitamin D levels with melanoma death. In this study, we further explored the associations of these with melanoma in addition to deprivation and socio-economic stressors. In this analysis of 2,183 population-ascertained primary cutaneous melanoma patients, clinical, demographic, and socio-economic variables were assessed as predictors of tumor thickness, melanoma death and overall death. Using the Townsend deprivation score, the most deprived group did not have thicker tumors compared to the least deprived. Of the World Health Organization 25x25 risk factors for premature death, smoking and body mass index (BMI) were independently associated with thicker tumors. Low vitamin D was also independently associated with thicker tumors. No socio-economic stressors were independent predictors of thickness. Smoking was confirmed as a key predictor of melanoma death and overall death, as were low vitamin D levels, independent of other measures of deprivation. Neither BMI nor the Townsend deprivation score were predictive in either survival analysis. We report evidence for the role of smoking, vitamin D, and BMI in melanoma progression independent of a postcode-derived measure of deprivation.

Vitamin D, vitamin A, the primary melanoma transcriptome and survival. Br J Dermatol 2016; 175 Suppl 2:30-34.

Abstract
Survival from melanoma is influenced by several, well-established clinical and histopathological factors, e.g. age, Breslow thickness and microscopic ulceration. We (the Section of Epidemiology and Biostatistics, University of Leeds) have carried out research to better understand the biological basis for these observations. Preliminary results indicated a protective role for vitamin D in melanoma relapse and that higher vitamin D was associated with thinner primary melanomas. Funding from the British Skin Foundation enabled JNB to establish a study of the effects of vitamin A in melanoma. The results suggested that vitamin A could reduce the protective effect of vitamin D in terms of overall survival. Therefore, we propose that vitamin D3 supplementation alone might be preferable to combined multivitamin preparations, where vitamin D supplementation is deemed to be appropriate. Proving a causal link between vitamin D and melanoma-specific survival is challenging. We have shown limited evidence of causation in a Mendelian randomization experiment (described in more detail later). Recent work in Leeds has also shown that higher vitamin D may be protective for microscopic ulceration. Taken together, vitamin D appears to be associated with less aggressive primary melanomas and may itself influence outcome. We continue to explore the role of vitamin D in melanoma survival and the optimum levels that might be crucial.

Prevalence and correlates of unmet supportive care needs in patients with resected invasive cutaneous melanoma. Ann Oncol 2014; 25:2052-2058.

Abstract
BACKGROUND Knowledge about supportive care needs in patients with cutaneous invasive melanoma is scarce. We examined the unmet needs of melanoma patients treated with surgery and factors associated with these needs to assist health professionals identify areas needing clinical attention. PATIENTS AND METHODS Cross-sectional multisite survey of UK patients ascertained 3 months to 5 years after complete resection of stage I-III cutaneous melanoma. Participants completed the following validated questionnaires: Supportive Care Needs Survey (SCNS-SF34 with melanoma module), Hospital Anxiety and Depression Scale and 51-item Functional Assessment of Cancer Therapy-Melanoma quality-of-life scale. RESULTS A total of 472 participants were recruited [319 (67%) clinical stage I-II). Mean age was 60 years (standard deviation = 14) and 255 (54%) were female. One hundred and twenty-three (27%) participants reported at least one unmet need (mostly 'low' level). The most frequently reported unmet needs were fears of cancer returning (n = 138, 29%), uncertainty about the future (n = 119, 25%), lack of information about risk of recurrence (n = 112, 24%) and about possible outcomes if melanoma were to spread (n = 91, 20%). One hundred and thirty-eight (29%) participants reported anxiety and 51 (11%) depression at clinical or subclinical levels. Patients with nodal disease had a significantly higher level of unmet supportive care needs (P < 0.001) as did patients with anxiety or depression (P < 0.001). Key correlates of the total SCNS-SF34 score for unmet supportive care needs were younger age (odds ratio, OR = 2.23, P < 0.001) and leaving school early (OR = 4.85, P < 0.001), while better emotional (OR = 0.89, P < 0.001) and social well-being (OR = 0.91, P < 0.001) were linked with fewer unmet needs. Neither patients' sex nor tumour thickness was associated with unmet needs. CONCLUSIONS Around a quarter of melanoma patients may have unmet support needs in the mid to long term after primary treatment. In particular, patients who are younger, less educated, distressed or socially isolated could benefit from more support.

Abstract
BACKGROUND To optimise predictive models for sentinal node biopsy (SNB) positivity, relapse and survival, using clinico-pathological characteristics and osteopontin gene expression in primary melanomas. METHODS A comparison of the clinico-pathological characteristics of SNB positive and negative cases was carried out in 561 melanoma patients. In 199 patients, gene expression in formalin-fixed primary tumours was studied using Illumina's DASL assay. A cross validation approach was used to test prognostic predictive models and receiver operating characteristic curves were produced. RESULTS Independent predictors of SNB positivity were Breslow thickness, mitotic count and tumour site. Osteopontin expression best predicted SNB positivity (P=2.4 × 10⁻⁷), remaining significant in multivariable analysis. Osteopontin expression, combined with thickness, mitotic count and site, gave the best area under the curve (AUC) to predict SNB positivity (72.6%). Independent predictors of relapse-free survival were SNB status, thickness, site, ulceration and vessel invasion, whereas only SNB status and thickness predicted overall survival. Using clinico-pathological features (thickness, mitotic count, ulceration, vessel invasion, site, age and sex) gave a better AUC to predict relapse (71.0%) and survival (70.0%) than SNB status alone (57.0, 55.0%). In patients with gene expression data, the SNB status combined with the clinico-pathological features produced the best prediction of relapse (72.7%) and survival (69.0%), which was not increased further with osteopontin expression (72.7, 68.0%). CONCLUSION Use of these models should be tested in other data sets in order to improve predictive and prognostic data for patients.

Abstract
BACKGROUND Atypical naevi are common benign skin lesions but are also recognized both as precursors of and risk factors for melanoma. It is therefore imperative to excise those lesions that are either likely to progress or are already progressing to melanoma. Clinically, however, it may be difficult to distinguish these from benign atypical naevi with bland histology. OBJECTIVES To analyse the clinical characteristics of excised melanocytic lesions and to identify the predictors of severe histological atypia/melanoma in situ and invasive melanoma. METHODS The case notes of 434 patients who had melanocytic lesions removed at a pigmented lesion clinic were studied retrospectively. A single pathologist reviewed the excised lesions and clinical characteristics predictive of malignancy were identified. RESULTS The best predictors of melanoma were older age, history of change and site on an extremity, but only older age was predictive of severe histological atypia/melanoma in situ as opposed to mild to moderate atypical histology. CONCLUSIONS These results confirm the difficulty of differentiating accurately between benign atypical naevi and borderline lesions or early melanoma in a clinical setting. It is therefore necessary to have a sufficiently low threshold for excision to avoid missing early melanomas, particularly in older patients presenting with lesions on the extremities.

Abstract
Laryngo-onychocutaneous syndrome (LOCS) is a condition characterized by erosive or ulcerative skin lesions associated with excessive granulation tissue, at sites of trauma such as the digits, elbows and knees. Similar lesions can occur within the conjunctival mucosa, leading to corneal scarring and blindness. The main complications, however, occur in the respiratory tract, where a similar process of erosions and subsequent formation of granulation tissue causes airway obstruction which may lead to premature death. LOCS is now believed to be a nonblistering variant of junctional epidermolysis bullosa and to date there are no efficacious treatments available. We report a 16-year-old girl with LOCS who failed to respond to methylprednisolone and cyclophosphamide, but had a partial response to oral thalidomide with marked decrease in granulation tissue and tracheal secretions. Interruption of treatment resulted in prompt resurgence of the granulation tissue which was again controlled by reintroduction of thalidomide. We propose that in the absence of effective therapies for LOCS, a trial of thalidomide in these patients should be considered.

Abstract
The aim of this study was to investigate recent trends in incidence, mortality and survival in patients diagnosed with malignant melanoma (MM) in relation to stage (Breslow thickness). Cases of primary invasive and in situ MM diagnosed between 1st January 1993 and 31st December 2003 in the former Yorkshire Health Authority were identified from cancer registry data. Over the study period, the incidence of invasive MM increased from 5.4 to 9.7 per 100,000 in male subjects and from 7.5 to 13.1 per 100,000 in female subjects. Most of this increase was seen in thin tumours (< 1.5 mm). Thin tumours were more likely to be diagnosed in the younger age groups and be classified as superficial spreading melanoma. In situ melanoma rates increased only slightly. Over the same time period, mortality rates have been relatively constant in both male and female subjects. Five-year relative survival varied from 91.8% (95% CI 90.4-93.1) for patients with thin tumours to 41.5% (95% CI 36.7-46.3) for those with thick tumours. In multivariable analyses, Breslow thickness was the most important prognostic factor. Age, sex and level of deprivation were also identified as independent prognostic factors. The trends in incidence suggest that the increase is real, rather than an artefact of increased scrutiny, implying that primary prevention in the Yorkshire area of the UK has failed to control trends in incidence. Mortality, in contrast, appears to be levelling off, indicating that secondary prevention has been more effective.

Abstract
BACKGROUND Desmoplastic melanoma (DM) is an uncommonly encountered type of malignant melanoma. The clinical appearance of DM can be highly variable and thus, diagnosis of this tumour is difficult and very often may mislead the physician. OBJECTIVES To make a critical review of the contemporary literature on DM, to pool the data from published studies and to evaluate the clinical and morphological characteristics of this neoplasm. METHODS All studies or reports on DM including 10 or more participants with reported clinical and histological characteristics of the tumour were included. RESULTS In the 17 studies that met the inclusion criteria a total of 856 patients with DM was reported. There was a male predilection, with a male/female ratio of almost 2 : 1 (63% of the lesions were diagnosed in males). The head and neck were the most common sites of DM for both sexes (53.2%). The data confirmed that DM usually has an advanced Breslow thickness at the time of presentation. Histopathological diagnosis of DM is sometimes difficult and the absence of pigmentation is probably the major cause for failure to recognize DM histologically. The pooled data from included studies showed that the incidence of nodal metastasis is lower in patients with DM than in patients with other forms of cutaneous melanoma. CONCLUSIONS Prompt definitive surgical excision is the treatment of choice for DM. Improved knowledge of the clinical behaviour and histological features of DM is important for more effective management of patients with DM.

Abstract
Cutaneous granulomas are uncommon in primary immunodeficiency disorders. We report cutaneous granulomas in a child with ataxia telangiectasia (AT) and compare the clinical course with similar lesions in an adult with common variable immunodeficiency (CVI). A 4-year-old female with AT developed cutaneous granulomas as erythematous plaques. The largest lesion appeared on her left cheek and continued to progress despite treatment with topical and intralesional steroids. Disease control was obtained initially with oral antibiotics and low-dose oral steroids. On cessation of oral steroids, significant relapse of the facial granuloma occurred. Pulsed and then oral steroids were required to stop the disease process leaving significant scarring. The second case is of cutaneous granulomas in a 66-year-old man, with CVI, who presented with an erythematous reticulate rash on the legs. We consider it useful to report this patient here as disease control was obtained in a similar way with systemic immunosuppression. In this patient a combination of oral steroids and azathioprine was used. These cutaneous granulomas are thought to be a manifestation of immune dysregulation. No infectious cause has been found so far. We recommend the use of broad-spectrum antibiotics in conjunction with systemic steroids for progressive granulomas, as these patients are immunosuppressed and infection with an unidentified organism cannot be excluded.

Abstract
BACKGROUND Several epidemiological studies have suggested an association between cutaneous melanoma and non-Hodgkin's lymphoma. METHODS We pooled the data from seven cohort studies and calculated the risk of secondary occurrence of cutaneous melanoma after non-Hodgkin's lymphoma, and of non-Hodgkin's lymphoma subsequent to the occurrence of cutaneous melanoma. RESULTS There were 137 612 patients with primary non-Hodgkin's lymphoma and 109 532 patients with primary cutaneous melanoma. We found a statistically significant increased risk of non-Hodgkin's lymphoma among cutaneous melanoma survivors [standardised incidence ratio (SIR) 2.01, 95% confidence interval (CI) 1.79-2.24] and cutaneous melanoma among non-Hodgkin's lymphoma survivors (SIR 1.41, 95% CI 1.26-1.58). CONCLUSION Our study confirmed an association between cutaneous melanoma and non-Hodgkin's lymphoma occurring in the same patient indicative of a need to examine further the role of the common risk factors.

Abstract
BACKGROUND Sentinel lymph node biopsy (SLNB) is a minimally invasive procedure used accurately to stage nodal basins at risk of occult metastases. There are no data as yet to show a survival benefit from SLNB and its use remains controversial. If Breslow thickness of the tumour correlates well with positive SLNB, it could be used to select patients for SLNB. METHODS A quantitative systematic review of published studies on SLNB in patients with melanoma available by September 2001 was performed. RESULTS Twelve studies containing 4218 patients with stage I and II melanoma were identified; 17.8 (95 per cent confidence interval 16.7 to 19.0) per cent of patients had nodal micrometastases detected by SLNB. The incidence of micrometastasis in sentinel nodes correlated directly with Breslow tumour thickness; it was 1.0 per cent for lesions of less than or equal to 0.75 mm, 8.3 per cent for 0.76-1.50 mm, 22.7 per cent for 1.51-4.0 mm and 35.5 per cent for more than 4.0 mm. CONCLUSION The Breslow thickness of primary melanoma predicts the presence of a sentinel node metastasis. The published data are not sufficient to demonstrate a correlation between other known prognostic indicators and a positive SLNB.

Abstract
In 2001, a short postal questionnaire regarding the management of regional lymph nodes in patients with cutaneous malignant melanoma was sent to 69 NHS departments of plastic and reconstructive surgery in the UK. Questionnaires were returned by 53 units, giving a response rate of 76.8%. Of these 53 units, 49 reported that they treat patients with primary malignant melanoma. There was considerable variation in the number of melanoma patients managed by each unit. This survey confirmed that elective lymph-node dissection is not routinely practiced in the UK; observation and therapeutic lymph-node dissection for patients who develop regional metastasis is the preferred pattern of care. The majority of centres in the UK do not use sentinel lymph node mapping: only 15 of the 49 units do so (30.6%). The number of sentinel lymph node biopsies performed in each unit varied significantly. There was considerable variation in the materials used and the process of care for sentinel lymph node biopsy. On the basis of this current practice, we recommend the setting up of a prospective clinical melanoma register to record the surgical treatment of melanoma patients.

Abstract
BACKGROUND Lentigo maligna (LM) is the in situ phase of LM melanoma (LMM). There is a paucity of data on the natural history of LM, the risk factors for progression to LMM and on treatment outcomes of the various modalities used. OBJECTIVES To investigate our impression that this, combined with the difficulties of treatment for large lesions particularly in the elderly and infirm, has led to considerable variation between dermatologists in the management of LM within the U.K. METHODS A postal questionnaire survey was performed to establish current practice. RESULTS One hundred and seventy clinicians representing one-third of U.K. consultant dermatologists responded. Fifty-seven per cent of the dermatologists reported treating only one to four LMs per year, 30% treated five to 10 LMs per year and only 13% treated more than 10 LMs per year. Ninety-four per cent of the respondents routinely took an initial biopsy to confirm the diagnosis and plan treatment. The preferred treatment option was dependent on the age of the patient. Dermatologists were far more likely to use surgery for patients under the age of 60 years and more likely to use cryotherapy/radiotherapy or merely to observe with increasing age. Where surgery was used, the excision margins chosen ranged from 0 to 10 mm. CONCLUSIONS This survey highlights that a significant proportion of U.K. dermatologists is managing small numbers of LMs each year. On the basis of this current practice and the data in the literature on the recurrence rates for the different modalities, we propose an algorithm for treatment options. The survey, however, showed no consensus between dermatologists regarding surgical margins for excision, which is reflected in the literature; further studies to establish this are required.

Abstract
A heterohybridoma cell line producing the human monoclonal antibody (MoAb) MDT.1 has been established. The heavy chain of MoAb MDT.1 is encoded by the VH gene segment V4-34 (previously designated VH4-21), and the light chain is encoded by the V kappa 1-L12a gene segment, both in germline configuration. MDT.1 has reactivity against lipid A, double- and single-stranded DNA, red blood cell associated i antigen, and ganglioside antigens. In a panel of tumour cell lines, MDT.1 reacted specifically with melanoma cells and other tumour cells of neuroectodermal origin. Cellular recognition appears to be via tumour-associated ganglioside antigens, and may involve the minimal essential epitope NeuNac alpha 2-->3Gal beta 1-->-4Glc-. Binding to ganglioside antigen is inhibited by the monoclonal anti-idiotypic antibody 9G4. Since the 9G4 idiotope is located in framework region 1 (FWR1) of V4-34-encoded antibodies, this region is likely to be involved, either directly or indirectly, in ganglioside binding. The complementarity-determining region 3 (CDR3) of MDT.1 is arginine rich, with five out of 12 residues being arginine and these residues are candidates for interaction with the negatively charged ganglioside. The ability of MoAb MDT.1 to recognise ganglioside antigens is associated with potentially useful anti-tumour activity.

Abstract
The relationship between risk of cutaneous malignant melanoma and total body and site-specific naevus counts and other host factors was investigated in a Caucasian population aged 15-84 years in New South Wales, Australia. The study sample comprised 244 cases with melanoma diagnosed in 1989-1993, and 276 controls. The strongest relationship was with total body naevus count. Risk of melanoma was raised 12 times in those with more than 100 naevi compared with those with less than 10. There were also strong risks, with odds ratios of 5 or more, associated with having multiple atypical naevi, multiple large naevi, high naevus counts in sun-exposed or sun-protected areas and being unable to tan on repeated sun exposure. The effect of inability to tan was stronger at younger than older ages. Lesser risks, with odds ratios of 2-3, were associated with being prone to burn on sun exposure, having many freckles as a child and having red hair. The site distribution of naevi in males compared with females resembled the distribution of melanoma by sex. Risk of melanoma of the back was significantly more closely related to back naevus count than naevus count for the remainder of the body. For other anatomical sites, naevus count was non-significantly more closely related to naevus counts at that site than counts over the remainder of the body. Naevus count declined with age in both cases and controls. In those aged under 40, having 100 or more naevi was associated with an aetiological fraction (AF) of 41%. In those aged 60 and over, however, the AF associated with this number of naevi was only 5%.
