Study information
Scientific title
Three non-invasive treatment options of superficial basal cell carcinoma: photodynamic therapy (PDT) vs imiquimod vs 5-fluorouracil: TTOP-sBCC trial
Acronym
TTOP-sBCC
Study hypothesis
There is no significant difference in recurrence rate and cosmetic outcome between the three treatment options. There will be a significant difference in cost effectiveness, PDT is expected to be much more expensive than the other two treatment options.

Condition
Superficial basal cell carcinoma
Intervention
Arm 1: Photodynamic therapy with Metvix®, 2 times 37 J/cm^2 with one week between the two sessions. Lamp used: Omnilux PDT™, Waldmann PDT™ or Aktilite PDT™ (Galderma).
Arm 2: Imiquimod (Aldara®): 5/7 days, once a day for 6 weeks
Arm 3: 5-fluorouracil (Efudix®): 7/7 days, two times a day for 4 weeks
Follow up: 3 months-12 months (-2 years-3 years-4 years-5 years)
Intervention type
Drug
Phase
Not Applicable
Drug names
Imiquimod, 5-fluorouracil.
Primary outcome measures
1. Clearance rate 3 months after the end of interventions
2. Recurrence rate 1 year after the end of interventions
Secondary outcome measures
1. Cost effectiveness
2. Patient preference, assessed by a questionnaire 1.5 years after the start of the study
3. Compliance, assessed by a questionnaire based on items of the Brief Medication Questionnaire (ref: Svarstad BL et al. The Brief Medication Questionnaire: a tool for screening patient adherence and barriers to adherence. Patient educ couns. 1999 Jun; 37(2): 113-24).
4. Side effects (pain), assessed using a questionnaire during treatment
5. Cosmetic outcome at 3 months and 1 year, assessed by both patient and one blinded medical doctor using the Patient and Observer scale (ref: Draaijers LJ et al. The patient and observer scare assessment scale: a reliable and feasible tool for scar evaluation. Plast Reconstr Surg. 2004 Jun; 113(7): 1960-5) and a 5-point scale.
