Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intralesional triamcinolone acetonide (TAC; 40mg/mL) for cutaneous squamous cell carcinomas (cSCCs) affecting the lower limb in elderly patients. TAC will be administered in clinic as a single injection by dermatologists and melanoma surgeons to a maximum volume of 1mL depending on tumour size.
Intervention code [1] 320567 0
Treatment: Drugs
Comparator / control treatment
Intralesional normal saline. This will be administered in clinic as a single injection by dermatologists and melanoma surgeons to a maximum volume of 1mL (dependent on tumour size)
Control group
Placebo

Outcomes
Primary outcome [1] 327538 0
Size of cSCCs (mean of two perpendicular diameters) 5 weeks after administration of intralesional TAC or placebo (normal saline). All tumour measurements will be performed in two perpendicular diameters using measurement calipers (to 0.2mm; John Bull). Photographs of treated tumours including a measurement scale will also be taken.
Timepoint [1] 327538 0
5 weeks after intralesional treatment
Secondary outcome [1] 395587 0
Effect of punch biopsy on tumour size. All tumour measurements will be performed in two perpendicular diameters using measurement calipers (to 0.2mm; John Bull). Photographs of tumours including a measurement scale will also be taken before biopsy and immediately before TAC or saline injection to assess this secondary outcome.
Timepoint [1] 395587 0
2 weeks post diagnostic biopsy to confirm SCC; injection of TAC or saline will then be done at this 2 week visit following the 2 week measurements.
Secondary outcome [2] 395592 0
Grade of cSCCs that are later biopsied or excised. This will be determined as per standard histopathology assessment by specialist histopathologists, as per standard clinical practice.
Timepoint [2] 395592 0
5 weeks post intralesional injection
Secondary outcome [3] 395595 0
Safety and tolerability (adverse events). Potential adverse effects include erosion at treatment site (identified by participant self report and review at study visits and at interim visits as appropriate). Allergic local reaction to the injected steroid is rare, but would be identified by participant self report and review at study visits and at interim visits as appropriate. We do not anticipate other adverse effects.
Timepoint [3] 395595 0
5 weeks post intralesional injection
Secondary outcome [4] 395596 0
Effect on Lower Extremity Functional Scale ( J. M. Binkley et al. The Lower Extremity Functional Scale (LEFS): scale development, measurement properties, and clinical application. North American Orthopaedic Rehabilitation Research Network, Physical therapy, 1999, 79, 371-383).

Eligibility
Key inclusion criteria
1. Aged 70 years or older
2. Lower limbs clinically deemed to be high risk for wound healing (including but not limited to diabetes mellitus; chronic venous disease changes affecting the lower limb; lipodermatosclerosis; history of lower limb cellulitis; history of poor wound healing on lower legs; lower limb oedema)
3. Potential participants must have at least one lesion on the legs clinically consistent with low-grade SCC. Biopsy would be taken (3mm punch) as per standard clinical practice. If confirmed to be SCC, the tumour(s) must be histologically proven primary low-grade cutaneous SCC of the lower limb
4. Low-grade tumours must have zero high-risk factors as per Brigham and Women’s Hospital Tumour Staging system for cSCC. These risk factors include:
- Diameter greater than or equal to 2cm
- Poorly-differentiated histology
- Perineural invasion greater than or equal to 0.1mm
- Tumour invasion beyond fat
5. Patient agreeable to delay in surgical excision. It should be noted that the 5 week duration of the trial falls within usual time to excision of well-differentiated cSCC on the lower limbs in the clinics which is 1-2 months.
6. Willingness and ability to provide informed consent and willingness to participate and comply with the study requirements.
Minimum age
70 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Histologically proven cSCC that are moderately or poorly differentiated
2. Unable to follow up for the duration of the study due to frailty, geographical or social reasons
3. Known contraindication to injection of triamcinolone acetonide (such as hypersensitivity to ingredients).
4. Patient prefers surgical excision
5. Patient undertaking other treatment for the lesion or lesions (such as field treatments, radiotherapy, photodynamic therapy)
6. Immune suppression (including transplant recipients, chronic haematological malignancies, immune-suppressive medications for autoimmune disorders)

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment; sealed opaque envelopes
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
After consent and enrolment, eligible lesions will be randomised in a 1:1 ratio to intervention or control groups. For this small participant group, randomisation will be done via a blocked randomisation list, stratified by gender (Sealed Envelope Ltd. 2020: https://www.sealedenvelope.com/simple-randomiser/v1/lists).
