Conclusion: It seems crucial to spare the lower third of the vagina in the absence of tumor involvement. However, clinical praticians sometimes ignore this aspect, particularly in centers treating few LACC. Improving the quality of external radiotherapy for cervical cancer is an important issue, and involves defining international quality criteria for radiotherapy. Systematic treatment by a sexologist nurse is essential support care for these young patients. It is likely that these rare tumours could benefit from comprehensive treatment at a referral centre.

Digital Poster Computed Tomography–Guided Needle Insertion in Interstitial Brachytherapy for Locally Advanced Cervical Cancer Talha Maqsood 1,2 , Salman Arif 2 , Muhammad Tariq Azeem 2 , Noman Sadiq 2 , Shahzeb Jawed 2 1 Clinical Oncology, Queen Elizabeth hospital, Birmingham, United Kingdom. 2 Radiation Oncology, Combined Military Hospital, Rawalpindi, Pakistan Purpose/Objective: Currently, no standard international guidance exists regarding placement of needles in interstitial intracavitary brachytherapy (IS-ICBT) for cervical cancer 1 . Ultrasound guided IS-ICBT is used in most of the cases 2 . This study aimed to assess the clinical feasibility, potential benefits and complications of using computed tomography (CT) guidance to enhance needle placement accuracy in IS-ICBT. Material/Methods: A total of 33 patients treated with interstitial brachytherapy using hybrid applicator Utrecht with needles, were included. For each patient, two CT scans were performed: (1) the first scan (CTpre-needle) was done immediately after the applicator was placed, without needles inserted, and (2) the second scan (CTpost-needle) was obtained once interstitial needles have been pushed through the hybrid applicators. The (CTpre-needle) images were used to assess if needles would help in the optimisation of dose to HR-CTV. It was also to used determine insertion depths based on the applicator position and proximity to organs at risk on the treatment day. The (CTpost-needle) images were then used for planning IS-ICBT. Dose to HRCTV and OARs was analysed in patients with Low(<30cm 3 ) and High Volume disease(>30cm 3 ).
