Brief Summary
Bile duct cancer is often diagnosed after curative options are no longer available. Stent therapy is used to keep the ducts open and can be combined with photodynamic therapy (PDT) to extend life expectancy. PDT requires an injection of photosensitizer after which light of a particular wavelength is applied endoscopically to kill the cancer cells. Drawbacks include not only high costs and poor availability, but foremost that patients have to avoid direct sunlight for a period of weeks. Radio frequency ablation (RFA) together with stent implantation constitutes an alternative by which the cancer cells are killed through heat, also applied endoscopically. The RFA technology is more widely available and easier to deploy. However, it has not been studied extensively and no randomized trials exist comparing the two methods. This trial will compare survival in patients with a particular bile duct cancer depending on whether they receive PDT or RFA. Moreover, data will be collected on side-effects and quality of life.

Outcome Measures
Primary Outcomes (1)
Overall survival
Hazard ratio from a Cox regression model will be used to compare randomization arms. Covariates will be stratification variables, classification of local inoperability, use of prophylactic antibiotics, Bismuth type and time between diagnosis and beginning RFA/PDT.
through study completion, an average of 1 year
Secondary Outcomes (18)
Overall survival (complementary perspective: median survival time)
through study completion, an average of 1 year
Overall survival (complementary perspective: two-year overall survival)
up to two years
Overall survival (complementary perspective: restricted mean survival on a time horizon of two-years)
through study completion, an average of 1 year
Days alive and out of hospital up to two years
up to two years
Quality of Life (QoL) measured using QLQ-C30 at various points in time after randomization (V2 (14 days), V3 (ca. 3 months), as a function of time after 6 months, adjusting for the baseline value)
through study completion, an average of 1 year
- +13 more secondary outcomes
Study Arms (2)
Photodynamic therapy (PDT)
EXPERIMENTALThe index procedure in all patients at baseline includes stenting, using an endoscopic retrograde cholangio-pancreatography (ERCP) procedure. The Intervention is at least one PDT at baseline according to the clinical routine of the trial site.
Radiofrequency ablation (RFA)
EXPERIMENTALThe index procedure in all patients at baseline includes stenting, using an endoscopic retrograde cholangio-pancreatography (ERCP) procedure. The Intervention is at least one RFA at baseline according to the clinical routine of the trial site.
Interventions
A photosensitizer, which is absorbed preferentially by tumour cells, is administered 24 - 48 hours prior to PDT. Light of a particular wavelength is then applied during endoscopic retrograde cholangiopancreatography (ERCP) to kill primarily cancer cells locally within the stenosis. Immediately after PDT treatment, new stents are inserted into all treated segments if needed.
RFA is also carried out as part of an ERCP. The RFA-probe is placed within the tumour stenosis and electrical current is applied. New stents are inserted into all treated segments if needed.
Eligibility Criteria
You may qualify if:
- Hilar cholangiocarcinoma (cytological or histological confirmation)
- Surgery is not planned
- Age ≥ 18 years
- Written informed consent
You may not qualify if:
- Tumour not accessible endoscopically
- Known hypersensitivity to porphyrins or to any of the other ingredients of the photosensitizer chosen
- Leukopenia (\< 2000/mm3)
- Thrombocytopenia (\< 100,000 / mm³)
- Severe, uncorrected coagulopathy (at the discretion of the physician)
- Suspected erosion of major blood vessels, because of the risk of life-threatening mass haemorrhage exists
- Porphyria (clinician's assessment) or other light-exacerbated diseases
- Severely impaired liver and or kidney function (at the discretion of the physician)
- Bedridden for more than 50% of the time (similar to ECOG (Eastern Cooperative Oncology Group) grade 3)
- Planned surgical procedure within the next 30 days
- Concurrent eye disease that will require a slit lamp examination within the next 30 days
- Prior radiotherapy within the last four weeks
- Previous PDT or RFA
- Planned liver transplantation
- Fertile women (within two years of their last menstruation) without appropriate contraceptive measures (implanon, injections, oral contraceptives, intrauterine devices, partner with vasectomy) while participating in the trial (participants using a hormone-based method have to be informed of possible effects of the trial medication on contraception)
