Outcome Measures
Primary Outcomes (2)
The fraction of enrolled patients wanting to take part in the decision making on radiation dose level
6 months after the last patient has finished radiotherapy
The fraction of enrolled patients choosing the lower radiation dose
6 months after the last patient has finished radiotherapy
Secondary Outcomes (13)
Number of patients with a V45Gy of less than 300 cc for the small bowel calculated on the basis of dose plans
6 months after the last patient has finished radiotherapy
Number of patients with a V35Gy of less than 75% for the bladder calculated on the basis of dose plans
6 months after the last patient has finished radiotherapy
Number of patients with treatment related adverse events as assessed by healthcare staff based on the common toxicity criteria (CTCAE v.4.0)
5 years after inclusion of the last patient
Quality of life as assessed by combined questionnaires EORTC QLQ CR30 and CR29
5 years after inclusion of the last patient
Subjective symptoms as assessed by LARS score (low anterior resection syndrome)
5 years after inclusion of the last patient
- +8 more secondary outcomes

Eligibility Criteria
You may qualify if:
- Squamous cell carcinoma of the anal duct or perianal (non-hairy skin, max 5 cm from the anal verge)
- T2-T4 N0-3
- Age ≥ 18 years
- Performance status 0-2
- Sufficient organ and bone marrow function defined as:
- Neutrophils ≥ 1.5 x 10\^9/L
- Thrombocytes ≥ 100 x 10\^9/L
- Curative intent radiation treatment deemed possible
- Patients chooses 1 of 3 options:
- I do not wish to decide on details of my treatment, but I would like to receive the standard treatment
- I want to receive the high radiation dose
- I want to receive the low radiation dose
- Written and orally informed consent
You may not qualify if:
- Non-resectable metastases
- Tumor \> 10 cm or the total tumor volume (incl. lymph node metastases) is too large to be included in an appropriate radiation field (after possible neoadjuvant chemotherapy)
- Pregnant or breastfeeding women
- Fertile women not willing to use effective contraception
- Serious co-morbidity that would hinder interfere with radiation treatment or hinder patient compliance (e.g. incapacity to understand or complete questionnaires)
