Title: Melanomas Excised in Primary Care vs Secondary Care Excision
Brief Summary: Melanoma is the most dangerous skin cancer and is becoming commoner, largely due to increased foreign holidays and use of sun-beds. Melanoma usually begins as a new or changing mole. If it is picked-up quickly enough it can be removed in a simple operation and effectively cured. GPs can do this operation and many are highly experienced and skilled in minor skin surgery. However, guidelines written by hospital specialists insist that all patients who might have a melanoma should not be treated by GPs, but should be referred to hospital. This contrasts with Australia, where melanoma is commoner and initial treatment by GPs is standard practice. This creates several potential problems. First, melanoma can be difficult to diagnose. Many moles that do not look concerning based on checklists do turn out to be melanoma, and the opposite frequently occurs too, moles that look worrying at initial examination are not melanoma. Second, people are becoming more skin aware and GPs are checking moles much more often. Sensibly many of these patients are being sent to hospital for a check, although most will not have melanoma. Third, as a result hospital skin clinics and minor surgery lists are becoming very busy and waiting times are ever increasing. Fourth, the many people who have a melanoma that is not clinically obvious are waiting an increasingly long time to have it diagnosed and treated in hospital, and this could actually mean that melanoma has more chance to spread while they wait. The investigators conducted studies on 1200 people diagnosed with a melanoma in Northeast Scotland between 1991 and 2008 and found that 20% of these people had had their melanoma diagnosed and first treated by their GP. These patients were no more likely to receive improper treatment than those that had been referred to hospital. Also people who had had their melanoma cut out by a GP were no more likely to die from melanoma, and they actually required less hospital visits afterward. This suggests that the guidelines could be changed to allow GPs to treat suspicious moles. The investigators think this will be better for patients and the NHS in the long-run. However, the investigators cannot recommend changes to the guidelines on the basis of local research. For this reason, the investigators wish to extend the study using data from 18,000 patients diagnosed with melanoma from across Scotland. The results of this inclusive study will inform how the health service should deal with the growing problem of suspicious moles in the future.


Options:
A: Comparison between one stop shop using reflectance confocal microscopy in the surgical treatment of BCC and current standard of care using punch biopsy, by assessing incomplete surgical excision on the final pathology report. (Within the first week after surgical excision of suspected BCC lesion)
B: The number of correctly identified basal cell carcinoma and the subtype by Reflectance confocal microscopy validated by histopathological examination of the excision specimen (Through study completion, an average of 3 years)
C: All-cause mortality (Until December 2015)
D: Sensitivity and Specificity (Within 120 days of Data Lock)

Answer: C
