Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients with locally advanced cervical cancer (FIGO 2018 stages 1B3–IVA) planned for primary radiotherapy including brachytherapy and without contraindications listed in the exclusion criteria.

Probably not a fit

Patients with tumor extension in the lower vagina third, those requiring a Geneva tandem with a specific size, or nylon allergy may not benefit from this approach.

What this trial studies

This phase I, single-center study aims to determine the feasibility of using a patient-tailored, 3D-printed ARCHITECT applicator in image-guided adaptive brachytherapy for locally advanced cervical cancer. Twenty-five patients will receive standard external-beam radiotherapy with concurrent chemotherapy, followed by HDR IGABT using the ARCHITECT applicator to optimize dose delivery to the high-risk target. The study follows EMBRACE II guidelines and evaluates technical practicality, treatment accuracy, and safety within existing clinical protocols. The ARCHITECT design targets optimized source channels to overcome limitations of conventional applicators. Deep hyperthermia is mentioned but not quantified as part of the protocol.

Why it matters

Potential benefit: If feasible, the ARCHITECT applicator could improve dose conformity to the tumor while sparing surrounding tissue, potentially enhancing treatment effectiveness.

How similar studies have gone: Prior brachytherapy work emphasizes image-guided adaptive approaches; this is a first-in-class patient-tailored 3D-printed applicator feasibility study.
