Description of intervention(s) / exposure
Participants will be recruited during routine follow up visits concerning previous renal/liver transplant.

Participation involves one visit with the study team where a full skin check will be performed. Swabs will be taken from standardised control sites of sun-damaged skin on the patients forearm, Squamous cell carcinomas (SCCs), peri-lesional skin to SCCs and actinic keratoses (AKs). The swabbing technique has been tested in previous pilot studies and involves using sterile swabs moistened in saline, to rub over the surface of the lesion/skin. Swabs are then stored in tubes for later DNA extraction and culturing.

All suspected SCCs will be recommended for routine excision and histology. We will request a copy of the subsequent pathology report to confirm SCC diagnosis. The member of the study team will also record information on demographic, and relevant medical history from the patient, as listed below. Clinical non-identifiable photographs of patient’s forearms and any SCCs will be taken.

Outcomes
Primary outcome [1] 298722 0
Primary outcome is the identification of microbial communities present on different lesions of the skin. Microbiome identification will be performed by extracting DNA from swabs collected of patient lesions, then sequenced using standard laboratory procedures.
Timepoint [1] 298722 0
baseline - after swab collection.
Secondary outcome [1] 325053 0
To support the primary outcome, we will also seek to identify microbiome from swabs using bacterial and yeast/fungi culture and isolation techniques.
Timepoint [1] 325053 0
baseline - after swab collection.

Eligibility
Key inclusion criteria
All participants in the study will need to have been immune-suppressed for over 1 year as a result of a kidney or liver transplant, prior to enrolling in the study. They will also need to be over the age of 40 years old. Participants are divided into three specific groups based on whether they have current SCCs (anywhere on the body) or AKs (on either forearm).
There will be 3 distinct groups recruited;
1. Renal/liver transplant recipients with over 1 year of immune-suppression, with no AKs
2. Renal/liver transplant recipients with over 1 year of immune-suppression, with at least 2 AKs on one forearm.
3. Renal/liver transplant recipients with over 1 year of immune-suppression, with one SCC located anywhere on the body.
Minimum age
40 Years
Maximum age

Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Exclusion criteria: Topical medicated creams to the area being sampled i.e. 5-fluorouracil, imiquimod, diclofenac sodium, ingenol mebutate, PDT, corticosteroid. Topical keratolytics.

Statistical methods / analysis
Once DNA is extracted, amplified and sequenced, then bioinformatics and biostatistical analysis will be able to identify any microbial populations associated with squamous cell carcinoma, actinic keratosis and sun-damaged skin.

This is an exploratory observational study, no formal sample size calculation was performed.
