Inclusion criteria

General Inclusion Criteria for All Patients:

  1. Patients newly diagnosed with histologically-proven MCC (either primary and/or regional nodal disease)
  2. Completion of clinical and radiological staging investigations, including CT imaging (or other modality) of regional nodal basin(s) and major viscera (and SLNB if clinically appropriate) to identify regional and distant metastases
  3. No confirmed distant metastases beyond the regional nodal basin (i.e. not stage IV disease)
  4. Suitable for radical treatment to achieve disease control
  5. Able to give valid informed consent
  6. Consent for collection of data and tissue samples and follow up
  7. Life expectancy six months or greater in relation to general fitness and co-morbidities

Additional Inclusion Criteria for Rational Compare:

  1. Patients newly diagnosed with histologically-proven primary MCC
  2. In the opinion of the SSMDT, the primary MCC can be encompassed both within a wide surgical margin and within a radiotherapy field, and the SSMDT is in equipoise regarding WLE or radiotherapy as first treatment
  3. A minimum margin of 1 cm surrounding the MCC achievable by either radiotherapy or surgery
  4. Consent for randomisation into Rational Compare

Exclusion criteria

Exclusion Criteria:

  1. The primary MCC has already been treated radically with WLE (surgical margins >10 mm) or radiotherapy
  2. Intended use of regional or systemic chemotherapy for MCC (including molecularly targeted agents and immunotherapy)

What researchers measure

Primary outcomes

  1. Time to loco-regional failure

    The time to loco regional failure for all patients is the time from randomisation to loco-regional treatment failure

    Time frame: Time from randomisation to 3 years

Secondary outcomes

  1. The proportion of patients alive and free of loco-regional disease

    (irrespective of whether loco-regional failure has been previously demonstrated)

    Time frame: Time from randomisation to 3 years

  2. Time to 'local failure'-the time from randomisation to macroscopic persistence, progression or recurrence between the primary site and regional nodal basin(s)

    (including in-field and in transit metastases)

    Time frame: Time from randomisation to 3 years

  3. Time to regional nodal failure

    Time to regional nodal failure

    Time frame: Time from randomisation to 3 years

  4. Time to distant progression

    Time to distant progression

    Time frame: Time from randomisation to 3 years

  5. Patient Progression free survival

    Patient Progression free survival

    Time frame: Time from randomisation to 3 years

  6. Patient survival

    Survival from randomisation

    Time frame: Time from randomisation to 3 years

  7. Quality of life assessed by questionnaires

    Quality of life assessed by QLQC30/ EQ-5L-5D questionnaire completion

    Time frame: Time from randomisation to 3 years
