Study type
Description of intervention(s) / exposure
Experimental Treatment Cream made up of Fluorouracil 5% plus Calcipotriol 0.005% Cream

This is an open label, prospective study comparing two topical treatments for skin cancer precursors using a blinded investigator and clinical photography to determine treatment outcome.

Consenting participants will be randomised to receive either twice daily combined topical 5FU-calcipotriol cream to the left or right side of the face, and topical 5FU (EfudixTM) to the alternate side of the face. The 5FU-calcipotriol cream will be used for 4 days for AK lesions, and for 6 days for IEC lesions. The 5FU (EfudixTM) will be used on AK and IEC lesions for 2-4 weeks, as tolerated (as per current clinical practice).

The participants will be applying the creams themselves at home (as per standard of care for topical treatments of skin cancer precursors. As per standard guidelines for use of topical 5 fluorouracil, participants will be advised to apply one "pea sized" amount of cream to each cheek (left and right), forehead and chin.

To monitor adherence to treatment, patients will complete a treatment cream diary throughout the duration of treatment.

Treatment: Drugs
Comparator / control treatment
Standard Care for Cutaneous Actinic Keratosis [AK] and Intraepidermal Carcinoma [IEC] Lesions. This treatment involves Fluorouracil 5% [5FU Cream]. The control treatment will be applied to the opposite side of each participants' face (i.e. the side not receiving the trial intervention).
Control group

Primary outcome [1] 328497 0
Primary outcome: patient preference for one treatment intervention over the alternative as determined by study survey. The survey will be completed at the below timepoints.
Timepoint [1] 328497 0
3 months, 1 year and 2 years post intervention completion
Secondary outcome [1] 399201 0
Secondary outcome: change in number of precancerous lesions pre and post treatment intervention (measured using baseline and repeat severity scores). Scoring has been specifically designed for the study and will be assessed by the principal investigator. Scoring will be based on number of actinic keratoses and overall level of solar damage.

Statistical methods / analysis
Data analysis will be conducted with statistical support via the Sunshine Coast Hospital and Health Service (SCHHS) Biostatistics & Bioinformatic Clinic. Descriptive statistics will be reported as mean and standard deviation (SD) for normally distributed continuous data, median and interquartile range (IQR) for non-normally distributed data and frequencies and percentages for categorical data. Categorical data will be compared with Chi-squared test or Fisher’s exact test where appropriate. For continuous data a Shapiro-Wilk test will performed to assess the distribution of the data. If the distribution is normal, a paired -student t-test will be performed, If not a Wilcoxon signed rank test.

Brief summary
Cutaneous Actinic Keratosis (AK) and Intraepidermal Carcinoma (IEC) lesions are precursors of skin cancer. This study aims to assess the effectiveness of 5FU (EfudixTM) skin cream alone, compared to a combined 5FU-calcipotriol skin cream, for treating these skin cancer precursors.

Who is it for?
You may be eligible for this study if you are aged between 18 to 85 years, and you have skin cancer precursors of AK and IEC lesions. People who have been diagnosed with skin cancer will not be eligible for this study.

Study details
All participants who choose to enrol in this study will be asked to apply the single skin cream on one side of the face, and the combined skin cream on the other side of the face. Each cream will be applied twice daily. The single cream will be used for 2-4 weeks, as tolerated; while the combined cream will be used for 4-6 days. The allocation of the side of the face (left/right) to the cream treatment will be random. After 3 months, 1 year, and 2 years, we will ask for your preference of either the single or double cream, and assess changes in the skin cancer precursor lesions.

It is hoped this research will determine the effectiveness of a combined skin cream in treating skin cancer precursors, which may reduce the risk of developing skin cancer.
