To assess the use of MRI-determined tumour regression grading (TRG) in local response assessment and detection salvageable early relapse after chemoradiotherapy (CRT) patients with anal squamous cell carcinoma (ASCC). From a prospective database ASCC managed through centralised multidisciplinary team, 74 who completed routine post-CRT 3- 6-month MRIs (2009–2012) were reviewed. Two radiologists blinded to outcomes consensus read retrospectively assigned TRG scores [1 (complete response) 5 (no...

Prediction of clinical complete response in rectal cancer before neoadjuvant chemo-radiotherapy treatment enables selection. Patients predicted to have could chemo-radiotherapy, and others additional doublet chemotherapy at this stage their improve overall outcome. This work investigates the role variables predicting response. Using UK-based OnCoRe database (2008 2019), we performed a propensity-score matched study 322 patients who received chemoradiotherapy. We collected pre-treatment...

Growing subsets of patients with metastatic colorectal cancer (CRC) are being considered for treatment curative intent. Accurate restaging potentially resectable hepatic or pulmonary metastases is therefore crucial optimal management. This article presents data to assess the role 18-fluoro-deoxyglucose ((18)FDG) positron emission tomography/computed tomography (PET/CT) in CRC.A total 341 liver and/or CRC underwent (18)FDG PET/CT between 1st April 2007 and 31st August 2008 at our unit.

Introduction The standard of care for patients with localised rectal cancer is radical surgery, often combined preoperative neoadjuvant (chemo)radiotherapy. While oncologically effective, this treatment strategy associated operative mortality risks, significant morbidity and stoma formation. An alternative approach chemoradiotherapy to try achieve a sustained clinical complete response (cCR). This non-surgical management can be attractive, particularly at high risk surgical complications....

Abstract Background We evaluated oncological changes in patients with squamous cell carcinoma of the anus (SCCA) treated by chemoradiotherapy (CRT) from a large UK institute, to derive estimates contemporary outcomes. Methods performed treatment-cohort analysis 560 non-metastatic SCCA CRT over 25 years. The primary outcomes were 3-year loco-regional failure (LRF), 5-year overall survival (OS), and cancer-specific (CSS). developed prediction models; overlaid on published results historic...

Abstract Background Anal cancer is a rare with rising incidence. Despite the relatively good outcomes conferred by state-of-the-art chemoradiotherapy, further improving disease control and reducing toxicity has proven challenging. Developing validating prognostic models using routinely collected data may provide new insights for treatment development selection. However, due to rarity of cancer, it can be difficult obtain sufficient data, especially from single centres, develop validate...
