BACKGROUND: There is a growing population of cancer survivors at risk of treatment-related morbidity. This study investigates how potentially curative rectal cancer treatment influences subsequent function and health-related quality of life (HRQL) using data from a large-scale survey of patient-reported outcomes. METHODS: All individuals 12-36 months post-diagnosis of colorectal cancer in England were sent a survey in January 2013. The survey responses were linked with cancer registration, hospital admissions and radiotherapy data through the National Cancer Registration and Analysis Service...

AIM: To investigate second primary malignancy (SPM) risk after radiotherapy in rectal cancer survivors. METHODS: We used Taiwan's National Health Insurance Research Database to identify rectal cancer patients between 1996 and 2011. Surgery-alone, preoperative short course, preoperative long course, and post-operative radiotherapy groups were defined. The overall and site-specific SPM incidence rates were compared among the radiotherapy groups by multivariate Cox regression, taking chemotherapy and comorbidities into account...

BACKGROUND: This is an update of the original review published in 2007.Carcinoma of the rectum is a common malignancy, especially in high income countries. Local recurrence may occur after surgery alone. Preoperative radiotherapy (PRT) has the potential to reduce the risk of local recurrence and improve outcomes in rectal cancer. OBJECTIVES: To determine the effect of preoperative radiotherapy for people with localised resectable rectal cancer compared to surgery alone...

Background: Chemoradiation (CRT) or short-course radiotherapy (SCRT) are standard treatments for locally advanced rectal cancer (LARC). We evaluated the efficacy/safety of two neoadjuvant chemotherapy (NACT) regimens as an alternative prior to total mesorectal excision (TME). Methods/design: This multi-centre, phase II trial in patients with magnetic resonance imaging (MRI) defined high-risk LARC (>cT3b, cN2+ or extramural venous invasion) randomised patients (1:1) to FOLFOX + Bevacizumab (Arm 1) or FOLFOXIRI + bevacizumab (Arm 2) every 14 days for 6 cycles prior to surgery...

Intensity-modulated radiation therapy is recommended in anal squamous cell carcinoma treatment and is increasingly used in rectal cancer. It adapts the dose to target volumes, with a high doses gradient. Intensity-modulated radiation therapy allows to reduce toxicity to critical normal structures and to consider dose-escalation studies or systemic treatment intensification. Image-guided radiation therapy is a warrant of quality for intensity-modulated radiation therapy, especially for successful delivery of the dose as planned...

PURPOSE: Day-to-day shape variation in the rectum CTV results in considerable geometric uncertainties during rectal cancer radiotherapy. To ensure coverage a large CTV-to-PTV margin is required. The purpose of this study was to increase the accuracy of treatment delivery by building a population based library of planning CTVs for rectal cancer patients and to evaluate its potential for rectum PTV margin and PTV volume reduction. METHODS: Analysis was done retrospectively on 33 early-stage rectal cancer patients with daily repeat CTs who received short-course pre-operative radiotherapy in 5 fractions of 5 Gy...

BACKGROUND: Neoadjuvant chemotherapy (NAC) allows earlier treatment of rectal cancer micro-metastases but is not standard of care. There are currently no biomarkers predicting long-term progression-free survival (PFS) benefit from NAC. PATIENTS AND METHODS: In this single arm phase II trial, patients with non-metastatic magnetic resonance imaging (MRI)-defined operable rectal adenocarcinoma at high risk of post-operative metastatic recurrence, received 8 weeks of oxaliplatin/fluorouracil NAC then short-course preoperative radiotherapy (SCPRT) before immediate surgery...

BACKGROUND: Lateral nodal disease in rectal cancer remains a subject of debate and is treated differently in the East and the West. The predictive value of lateral lymph node and MRI-detected extramural vascular invasion (mrEMVI) features on oncological outcomes was assessed in this study. METHODS: In this retrospective cohort study, data on patients with cT3-4 rectal cancer within 8 cm from the anal verge were considered over a 5-year period (2009-2013). Lateral lymph node size, malignant features and mrEMVI features were evaluated and related to oncological outcomes...

Locally advanced rectal cancer (LARC) carries higher risks of local and distant recurrence when treated with surgical resection alone. Multiple treatment strategies have been investigated to reduce recurrence risk and improve survival. Currently, there are 3 primary strategies for managing LARC: (1) preoperative long-course radiotherapy (RT) combined with radiosensitizing chemotherapy, which is better tolerated than postoperative chemoradiotherapy and provides tumor downstaging and improved pathologic complete response (pCR), followed by postoperative chemotherapy; (2) preoperative short-course RT alone as an alternative strategy for reducing the risk of local recurrence, followed by adjuvant postoperative chemotherapy; and (3) total neoadjuvant therapy with induction chemotherapy followed by chemoradiotherapy to improve pCR and reduce the difficulty of delivering chemotherapy in the postoperative setting...

BACKGROUND AND PURPOSE: The role of preoperative short-course radiotherapy (SCRT) in rectal cancer treatment, when compared to long-course radiochemotherapy (LCRT), is still controversial. Thus the meta-analysis with trial sequential analysis (TSA) was performed to evaluate the long-term survival of SCRT and LCRT as therapeutic regimens for locally advanced rectal cancer. MATERIAL AND METHODS: PubMed, Embase, and the Cochrane Central Register of Controlled Trials were searched up to August 2017 for eligible studies...

Background: It is unclear whether emergency weekend colon and rectal cancer surgery are associated with worse outcomes (ie, weekend effect) because previous studies mostly used administrative data, which may insufficiently adjust for case-mix. Materials and Methods: Prospectively collected data from the 2012-2015 Dutch ColoRectal Audit (n=5,224) was used to examine differences in 30-day mortality and severe complication and failure-to-rescue rates for emergency weekend (Saturday and Sunday) versus Monday surgery, stratified for colon and rectal cancer...

BACKGROUND: The safety and efficacy of preoperative short-course radiotherapy had been verified in rectal cancer. However, the timing of surgery after radiation had not been well defined. Thus, we performed this meta-analysis to compare the interval time of surgery after short-course radiotherapy in rectal cancer: immediate surgery (<4 weeks) vs delayed surgery (>4 weeks). METHODS: We searched the PubMed, EMBASE, MEDLINE, and Cochrane Library database. The primary endpoints were survival rates and pathological outcomes, and the second endpoints included sphincter preservation rate, R0 resection rate and postoperative complications...

BACKGROUND: Radical resection by multivisceral resection of colorectal T4 tumours is important to reduce local recurrence and improve survival. Oncological safety of laparoscopic resection of T4 tumours is controversial. However, robot-assisted resections might have advantages, such as 3D view and greater range of motion of instruments. The aim of this study is to evaluate the initial results of robot-assisted resection of T4 rectal and distal sigmoid tumours. METHODS: This is a cohort study of a prospectively kept database of all robot-assisted rectal and sigmoid resections between 2012 and 2017...
