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

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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)
