Use of the Skin Cancer Quality of Life Impact Tool (SCQOLIT) - a feasibility study in non-melanoma skin cancer.

BACKGROUND: Incidence of non-melanoma skin cancers (NMSCs) is increasing and can significantly impact on quality of life (QOL), yet there are few studies evaluating patient-reported outcome measures (PROMs) in NMSC populations. We undertook a prospective feasibility study to evaluate a skin cancer-specific PROM, the Skin Cancer Quality of Life Impact Tool (SCQOLIT), in patients with a new diagnosis of NMSC. OBJECTIVES: (i) To establish acceptability of SCQOLIT in dermatology clinics, (ii) a descriptive analysis of SCQOLIT scores in NMSC. METHODS: Patients with histologically confirmed NMSC completed SCQOLIT, EQ-5D and a transition item. Questionnaires were completed at baseline and 3 months for group 1 ('low-risk' NMSC) and group 2 ('high-risk' NMSC) with additional questionnaires at 6-9 months for group 2. Patients participated in structured interviews. Clinician experience was captured through staff evaluation forms and a focus group. Acceptability and psychometric properties of SCQOLIT were assessed. RESULTS: Overall, 318 patients consented to participate. Mean SCQOLIT score at baseline was 5.33, with 2.6% of patients scoring ≥20. No ceiling effects were observed, whilst 13.9% scored 0. Validity was demonstrated against EQ-5D. Cronbach's alpha 0.84 demonstrated internal consistency. Thirteen patients were interviewed and thought SCQOLIT was comprehensive, captured impact on health-related QOL and helped express their needs to clinicians. Most clinicians found SCQOLIT 'very useful' or 'useful to some extent' in facilitating discussions. CONCLUSIONS: This feasibility study demonstrates that SCQOLIT is acceptable to patients and staff in dermatology skin cancer clinics. The psychometric properties of SCQOLIT confirm its utility in NMSC populations.

Patient preferences for topical treatment of actinic keratoses: a discrete-choice experiment.

BACKGROUND: The treatment of actinic keratosis (AK) is a potentially effective strategy for the prevention of cutaneous squamous cell carcinoma (cSCC). However, the patient perspective on potential benefits of AK treatment in terms of skin cancer reduction has received little attention to date. OBJECTIVES: (i) To investigate patient preferences for topical treatments for AK using a discrete-choice experiment (DCE); (ii) to evaluate patient willingness to trade between clinical benefit and medical burden. METHODS: The DCE was conducted as part of a study to establish the feasibility of a phase III randomized controlled trial evaluating the prevention of cSCC using currently available topical interventions. Preferences were elicited by asking patients to make a series of choices between treatment alternatives with different hypothetical combinations of attribute levels. Willingness to trade between treatment attributes was estimated using a flexible-choice model that allows for the heterogeneity of patient preferences. RESULTS: A total of 109 patients with AK completed the DCE. The majority of patients who expressed valid preferences were willing to accept some reduction in both prophylactic and cosmetic efficacy to reduce the burden of the treatment regimen, the severity of skin reaction and other adverse effects. Patients may reject treatment if the perceived therapeutic benefit is outweighed by the subjective burden of treatment. CONCLUSIONS: Evidence of significant variation in the perceived utility of treatments across patients highlights the importance of taking individual patient preferences into account to improve AK treatment acceptability and adherence.

Cutaneous hyperpigmentation and familial gastrointestinal stromal tumour associated with KIT mutation.

Gastrointestinal stromal tumours (GISTs) are mesenchymal tumours arising in the gastrointestinal tract. Early detection, before metastasis occurs, is important as complete surgical excision achieves cure. Approximately 85% of GISTs are associated with mutations in the KIT gene, and although the majority of GISTs are sporadic, familial GISTs have been identified. Several families with multiple GIST tumours have also been described with various cutaneous findings including hyperpigmentation, multiple lentigines, vitiligo and urticaria pigmentosa. We discuss a 6-year-old boy who presented with an unusual pattern of hyperpigmentation in association with a family history of GIST. A causative KIT mutation was identified in DNA from the pigmented skin and from the resected GIST, and the patient was referred to the Paediatric Gastroenterology department for GIST screening. The term 'GIST cutaneous hyperpigmentation disease' has been suggested previously for the association of familial GIST with cutaneous hyperpigmentation caused by a germline KIT mutation.

Management of naevus sebaceous: a national survey of UK dermatologists and plastic surgeons.

Naevus sebaceous (NS) is a congenital cutaneous hamartoma, which typically occurs on the head and neck. Historically, the treatment of choice was excision in infancy because of the potential for malignant transformation; however, recent studies suggest that this risk is < 1% and unlikely in childhood. We sent a questionnaire to UK dermatologists and plastic surgeons to investigate current management practice of NS. We found that almost a third of dermatologists still recommend excision for malignancy prevention, while over 90% of plastic surgeons consider excision, with 64% citing malignancy prevention as the reason. Plastic surgeons most commonly recommended excision in childhood, whereas dermatologists waited until adulthood. We have shown there is significant variation in practice across the UK in the management of naevus NS. It is important that patients across the UK receive the same standard of care, and therefore we advocate the development of evidence-based guidance for treatment of naevus NS.

Varix of the retromandibular vein within the parotid gland: case study.

OBJECTIVE: To report a case of varix of the retromandibular vein within the parotid gland. METHODS: Case report, and discussion of the appropriate selection and use of radiological investigation techniques. RESULTS: A 64-year-old lady who presented with unilateral tinnitus underwent a magnetic resonance imaging scan to exclude a vestibular schwannoma. The magnetic resonance scout images revealed an incidental finding of a hyperechoic mass within the parotid gland. The mass was most consistent with a pleomorphic adenoma. Ultrasound-guided fine needle aspiration cytology was arranged; the ultrasound identified the mass as a varix of the retromandibular vein and fine needle aspiration cytology was not performed. CONCLUSION: A varix of the retromandibular vein is a very rare cause of a parotid mass. Appropriate radiological investigations can prevent unnecessary invasive investigations or procedures.
