Study information
Scientific title
A trial comparing Metvix® photodynamic therapy followed by Mohs micrographic surgery against Mohs micrographic surgery alone for the treatment of basal cell carcinoma
Acronym
Study hypothesis
That using topical photodynamic therapy (PDT) prior to Mohs micrographic surgery (as an adjunct) in the treatment of basal cell carcinoma (BCC) will overall, reduce the post-Mohs wound defect size (mm^2) when compared to Mohs micrographic surgery alone
Ethics approval
Approved by St Thomas' Hospital Research Ethics Committee on 06/12/2005, reference number: 05/Q0702/219
Study design

Condition
Basal cell carcinoma (BCC)
Intervention
To assess whether the combination of PDT followed by Mohs micrographic surgery is superior to Mohs micrographic surgery alone in treating basal cell carcinoma in terms of reducing the post-Mohs wound defect and the mean number of stages required to achieve clearance
Intervention type
Other
Phase
Not Specified
Drug names
Primary outcome measure
1. To measure and compare the post-Mohs wound defect surface area (mm^2) in the two groups
2. To compare the mean number of stages required to clear the lesion by Mohs' micrographic surgery in the two groups
3. To compare recurrence rates of BCC at 12 months post-operatively. The lesion response will be defined as one complete response (complete clearance) or zero incomplete response (incomplete clearance).
Secondary outcome measures
1. To assess whether there is any reduction in size (surface area, mm^2) of the lesion, clinically with PDT prior to Mohs (in the Metvix® PDT group) including assessment of fluorescence between the first and second sessions of PDT
2. Cosmetic outcome at months 3, 6 and 12 after the Mohs surgery

Participant exclusion criteria
1. BCCs with less than 100 mm^2 in surface area
2. Clinically or histologically morphoeic basal cell carcinoma
3. Female of child-bearing potential
4. Subject with a history of porphyria, xeroderma pigmentosa or other photosensitive skin condition
5. Subject with known hypersensitivity to methyl 5-aminolevulinate, a similar compound or excipients of the cream
6. Subject who is at risk in terms of precautions and contraindications in the package insert for Metvix®
7. Subject who has participated in another investigational drug or device research study within 30 days of enrolment
8. Subject with a condition or who is in a situation, which in the investigators opinion may put the subject at significant risk, may confound the study results or may interfere significantly with the subjects participation in the study. This includes individuals unable to understand the implications or procedures of the trial, for example if they cannot adequately understand written or spoken English.
