E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to investigate if a more simple and flexible PDT treatment schedule (one single treatment session with re-treatment of non-complete responders-regime 1) for low-risk primary superficial or nodular BCC will be as effective as the standard and approved two-treatments one week apart. |
|
E.2.2 | Secondary objectives of the trial |
To investigate relationship between clinical and pathological tumour characteristics and the relationship between tumour recurrence rates with tumour thickness and histopathological subtypes and various immunhistochemical markers. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Inclusion Criteria
Patients • Males or females above 18 years of age. • Written informed consent.
Lesions • One or more primary histologically verified BCC, clinically assessed as of either superficial or nodular type.
|
|
E.4 | Principal exclusion criteria |
Exclusion Criteria Patients • Woman with child-bearing potential • Patients with Gorlin’s syndrome, porphyria, xeroderma pigmentosum, history of arsenic exposure or known allergy to MAL • Concomitant treatment with immunosuppressive medication • Patients with physical or mental conditions that most likely will prevent them from attending the follow-up visits
Lesions • Located within the mid-face-H-area • Longest diameter >15 mm on face and scalp, >30 mm on the trunk and >20 mm on the limbs • Any clinically evaluated pigmented or morpheaform lesions • Any lesions with prior treatment
|
|
E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint will be lesions cure rate and cosmetic outcome by treatment regime 1 compared to lesions cure rate by treatment regime 2, assessed 36 months after PDT. The number of lesion in need of a re-treatment 3 months following the first treatment session in regime 1 will be reported. Clinical suspected recurrences are confirmed by histology. Lesion response rate is defined as number of lesions in complete response at 12 and 36 months of follow-up. We will report on adverse advents occurring in relation to both treatment regimes from start of treatment to 3 months following last treatment. We will report on lesion recurrences among lesions treated with either regime 12 and 36 months after PDT. Cosmetic outcome will be determined by clinical assessment (visual inspection and palpation) 12 and 36 months after treatment. The results will be recorded on a 4-point ordinal scale as either excellent (absence of any stigmata other than scar formation after diagnostic punch biopsy), good (slight presence of fibrosis, atrophy or change of pigmentation), fair (moderate presence of fibrosis, atrophy or change in pigmentation) or poor (marked presence of fibrosis, atrophy or change in pigmentation).

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
12 and 36 month after intervention |
|
E.5.2 | Secondary end point(s) |
The secondary endpoint will be to investigate relationship between clinical and pathological tumour characteristics and tumour recurrences rates, tumour thickness, histopathological BCC subtypes and immunohistochemical markers. Recurrence rate defined both as”raw” (total number of recurrences divided by the total number of tumours treated) and”strict recurrence rate” (total number of patients with recurrence divided by number of lesions observed for at least 36 month) will be reported. Recurrence rate in relation to BCC subgroup analyses including clinical (superficial or nodular tumour), tumour size and histological characteristics will also be reported. BCC will on the basis of histological growth pattern be divided into two main types (aggressive or non-aggressive type). Tumours will additionally be studied with various immunohistochemical markers for expression of cell proliferation, invasiveness, vascularisation and growth factors.
