Preoperative chemoradiotherapy for oesophageal cancer: a systematic review and meta-analysis

2004

Background: The benefit of neoadjuvant chemoradiotherapy in oesophageal cancer has been extensively studied but data on survival are still equivocal. Objective: To assess the effectiveness of chemoradiotherapy followed by surgery in the reduction of mortality in patients with resectable oesophageal cancer. Methods: Computerised bibliographic searches of MEDLINE and CANCERLIT (1970–2002) were supplemented with hand searches of reference lists. Study selection: Studies were included if they were randomised controlled trials (RCTs) comparing preoperative chemoradiotherapy plus surgery with surgery alone, and if they included patients with resectable histologically proven oesophageal cancer wit…

Fully robotic Ivor–Lewis esophagectomy (RAMIE4) for esophageal cancer after emergency surgery and ligation of the gastroduodenal artery

2018

We report a case of a 69-year-old patient with esophageal cancer and severe upper gastrointestinal bleeding during neoadjuvant radiochemotherapy who required mass transfusion followed by complex emergency procedures. Despite endoscopic stenting, the bleeding recurred, and thus emergency open surgery was required. Gastric wedge resection of the minor curvature necessitated by perforation caused by the endoscopic stent maneuver and duodenotomy with ligation of the gastroduodenal artery, as the cause of persistent intraluminal bleeding, were performed. The already prepared gastric conduit during the emergency operation did not become ischemic, even though the gastroduodenal artery, left gastr…

Primary spinal Burkitt’s lymphoma: Case report and literature review

2021

Background:Burkitt’s lymphoma is a non-Hodgkin B-cell lymphoma, occurring mostly in Equatorial Africa. According to the WHO, classification is three different variants: sporadic, endemic, and immunodeficient-associated. Here, we present a patient with “sporadic” primary epidural Burkitt’s lymphoma resulting in chronic low back pain (LBP).Case Description:A 63-year-old female presented with a 2-month history of LBP and the left lower extremity sciatica. The thoracolumbar MRI showed a L5 irregular, osteolytic epidural lesion that was hypointense on T1-weighted images, hyperintense on STIR studies, and inhomogeneously enhanced with contrast. Additional hypointense lesions were also seen at the…

Prediction of N0 Irradiated Rectal Cancer Comparing MRI Before and After Preoperative Chemoradiotherapy

2017

Background: The prediction of lymph node status using MRI has an impact on the management of rectal cancer, both before and after preoperative chemoradiotherapy. Objective: The purpose of this study was to maximize the negative predictive value and sensitivity of mesorectal lymph node imaging after chemoradiotherapy because postchemoradiation node-negative patients may be treated with rectum-sparing approaches. Design: This was a retrospective study. Settings: The study was conducted at a tertiary care hospital. Patients: Sixty-four patients with locally advanced rectal cancer who underwent preoperative chemoradiotherapy and MRI for staging and the assessment of response were evaluated. Mai…

Can chemotherapy concomitantly delivered with radiotherapy improve survival of patients with resectable rectal cancer? A meta-analysis of literature …

2010

Summary Background There is clear evidence from two systematic reviews that radiotherapy (RT) reduces the risk of local recurrence in patients with resectable rectal cancer, though the data on survival are still equivocal. Objective To assess the effects of chemotherapy combined concomitantly with radiotherapy (CRT) on the increase of overall survival, and on the prevention of local recurrence and distant metastases. Data sources Computerized bibliographic searches of MEDLINE and CANCERLIT (1970–2008) were supplemented with hand searches of reference lists. Study selection Studies were included if they were randomized controlled trials (RCTs) comparing preoperative or postoperative CRT to p…

The impact of radiotherapy on survival in resectable gastric carcinoma: A meta-analysis of literature data.

2007

Summary Background The benefit of external radiotherapy for gastric carcinoma has been extensively studied, but data on survival are still equivocal. Objective To assess the effectiveness of surgery combined with preoperative radiotherapy or postoperative chemoradiotherapy in the reduction of all-cause mortality in patients with resectable gastric carcinoma. Methods Computerised bibliographic searches of MEDLINE and CANCERLIT (1970–2006) were supplemented with hand searches of reference lists. Study selection Studies were included if they were randomised controlled trials (RCTs) comparing mortality of surgery combined with preoperative radiotherapy or postoperative chemoradiotherapy to surg…

Definition of the Rectum An International, Expert-based Delphi Consensus

2019

Mini: A radiological, anatomic distinction between the rectum and sigmoid colon was agreed by consensus of international experts in rectal cancer using the Delphi Technique. Use of this landmark, “the sigmoid take-off,” may harmonize efforts in research and clinical practice to improve patient outcomes. Background: The wide global variation in the definition of the rectum has led to significant inconsistencies in trial recruitment, clinical management, and outcomes. Surgical technique and use of preoperative treatment for a cancer of the rectum and sigmoid colon are radically different and dependent on the local definitions employed by the clinical team. A consensus definition of the rectum…

Chimioradiothérapie des cancers de l’œsophage : quelles aires ganglionnaires faut-il irradier ?

2014

Esophageal cancer has a high likelihood of distant lymphatic spread even at an early stage. Radiotherapy plays a major role in the management of localized or locally-advanced esophageal cancer with a regional or distant lymph node involvement. Radiotherapy can sterilize micrometastatic nodes and cancer cells in transit in the peri-esophageal fat that are not removed by surgery. After preoperative chemoradiotherapy followed by monobloc esophagectomy including lymph node dissection above and below the diaphragm, the locoregional failure rate was around 3% in the Chemoradiotherapy for Esophageal Cancer followed by Surgery Study Group (CROSS) trial. This is significantly lower than that observe…

Minimally Invasive Approaches in Locally Advanced Cervical Cancer Patients Undergoing Radical Surgery After Chemoradiotherapy: A Propensity Score Ana…

2020

Abstract Purpose Chemoradiation (CT/RT) followed by radical surgery (RS) may play a role in locally advanced cervical cancer (LACC) patients with suboptimal response to CT/RT or in low-income countries with limited access to radiotherapy. Our aim is to evaluate oncological and surgical outcomes of minimally invasive radical surgery (MI-RS) compared with open radical surgery (O-RS). Patients and Methods Data for stage IB2–IVA cervical cancer patients managed by CT/RT and RS were retrospectively analyzed. Results Beginning with 686 patients, propensity score matching resulted in 462 cases (231 per group), balanced for FIGO stage, lymph node status, histotype, tumor grade, and clinical respons…
