Outcomes
Primary outcome [1] 296920 0
To estimate the rate of sentinel lymph node positivity in cT1N0 Merkel cell carcinoma, all patients in the study will have undergone a SLNB
Timepoint [1] 296920 0
SLNB is performed at baseline.
Primary outcome [2] 296921 0
Record the location of SLN identified, with reference to the location of the primary site
Timepoint [2] 296921 0
Recorded post SLNB at the 6 week post radiotherapy visit.
Primary outcome [3] 296922 0
Among the sentinel lymph node-negative patients, who are treated with radiotherapy to the primary site alone - to estimate the proportion of patients experiencing regional recurrence and/or death within two years. (Composite outcome)
Patients will undergo standard follow up including Ultrasounds of the nodal basin and scanning.
Timepoint [3] 296922 0
Patients will be followed up 6 weeks after Radiotherapy, then every 4 months for a minimum of 2 years.
Secondary outcome [1] 319709 0
Amongst patients who experienced recurrence within two years, to estimate the proportion of patients for whom sentinel lymph node mapping / biopsy was able to correctly identify the location of the lymph node region in which the recurrence was detected.
Timepoint [1] 319709 0
Patients will be followed up on a 4 monthly basis post Radiotherapy completion for a minimum of 2 years,

Statistical methods / analysis
Expected accrual is 10 patients per 12 months, resulting in 50 patients over a 5 year period
1. Amongst patients for whom the sentinel lymph node (SLN) could be identified, the proportion of cT1N0 patients with disease detected in the SLN will be estimated as a binary proportion together with its CI, by an exact method.
2. For each primary disease site (leg, arm, etc.) the number of patients for whom the location of the SLN is in each possible location (axilla, groin, neck or other) will be tabulated. For patients for whom the primary site drains to multiple lymph nodes i.e. multiple SLN’s), all drainage sites will be considered in the tabulation.
3. For SLN-negative patients, initial therapy consists of radiotherapy to the primary disease site. After initial therapy all patients are expected to be disease-free (with reference to the LN region). The Kaplan-Meier estimate of the proportion of patients experiencing regional recurrence within two years, together with its 95% CI will be provided. Death will be a censoring event.
4. For those patients for whom the SLN could be identified and for whom regional recurrence occurred within 2 years, the proportion of patients for whom the recurrence occurred in the lymph node region in which the SLN was found, will be estimated as a binary proportion, and a 95% CI for this proportion will be provided using an exact method
