The EXCISE Study - EXcisional treatment Comparison for In Situ Endocervical adenocarinoma

Print record Print record
Trial Information

Trial summary

The aim of this pilot study is to compare loop electrosurgical excision procedure to cold knife cone biopsy for treatment of adenocarcinoma in situ.

Who is it for?
You may be eligible to join this study if you are a woman aged between 18 and 45 years old and have been diagnosed with adenocarcinoma in situ (AIS) with lesions amenable to single pass excision.

Study details
AIS most frequently occurs in young women (less than 45 years of age) who may wish to preserve their fertility. If this is the case, there are two treatment options available: cold knife cone (CKC) biopsy or loop electrosurgical excisional procedure (LEEP).

In Australia, CKC is regarded as the 'gold standard' treatment for AIS. However, to date most AIS studies have been limited by small patient numbers and short follow-up periods. Further evidence is required to confirm if CKC is the superior treatment type for managing AIS.

Participants in this study are randomly allocated (by chance) to one of two groups. Participants in one group will have their lesions removed using LEEP, whilst participants in the other group will have their lesions removed using CKC.

Following treatment, all participants will undergo the 'Test of Cure' management pathway which includes follow-up examinations at 6 and 12 months post-treatment. Assessments for early complications and patient satisfaction will occur 6 weeks post-treatment.

We are hoping to perform a pilot research study to confirm the safety and feasibility of conducting a much larger clinical trial which would be the first to compare CKC and LEEP in this way. Study findings could potentially improve patients' experiences and alter treatment guidelines since potential advantages of LEEP include the avoidance of general anaesthesia, provision of treatment in an outpatient setting, lower morbidity and reduced rates of obstetric complications.
