Laparoscopic vs. open surgery for T4 colon cancer: A propensity score analysis

The study aimed to compare, using propensity score matching (PSM) analyses, the short- and long-term results of laparoscopic colectomy (LC) versus open colectomy (OC) in a bicentric cohort of patients with T4 colon cancer

Long-Term Results of Endoscopic Metal Stenting for Biliary Anastomotic Stricture after Liver Transplantation

(1) Background: Anastomotic biliary stricture (ABS) is a well-known complication of liver transplantation which can lead to secondary biliary cirrhosis and graft dysfunction. The goal of this study was to evaluate the long-term outcomes of endoscopic metal stenting of ABS in the setting of deceased donor liver transplantation (DDLT). (2) Methods: Consecutive DDLT patients with endoscopic metal stenting for ABS between 2010 and 2015 were screened. Data on diagnosis, treatment and follow-up (until June 2022) were collected. The primary outcome was endoscopic treatment failure defined as the need for surgical refection. (3) Results: Among the 465 patients who underwent LT, 41 developed ABS. It was diagnosed after a mean period of 7.4 months (+/−10.6) following LT. Endoscopic treatment was technically successful in 95.1% of cases. The mean duration of endoscopic treatment was 12.8 months (+/−9.1) and 53.7% of patients completed a 1-year treatment. After a mean follow-up of 6.9 years (+/−2.3), endoscopic treatment failed in nine patients (22%) who required surgical refection. Conclusions: Endoscopic management with metal stenting of ABS after DDLT was technically successful in most cases, and half of the patients had at least one year of indwelling stent. Endoscopic treatment long-term failure rate occurred in one fifth of the patients

Salvage Surgery for Esophageal Cancer: How to Improve Outcomes?

International audienceBACKGROUND:Locoregional recurrence rates after definitive chemoradiotherapy (dCRT) for locally advanced esophageal cancer (EC) are high. Salvage surgery (SALV) is considered the best treatment option in case of persistent or recurrent disease for operable patients, but SALV has been associated with increased morbidity and mortality. The aim of this study is to identify factors linked to outcomes after SALV to better select candidates and to optimize perioperative care.STUDY DESIGN:We retrospectively analyzed data from 308 consecutive SALV patients from a large multicenter European cohort. Univariate and multivariate analyses were performed to identify factors associated with in-hospital postoperative morbidity, anastomotic leakage (AL), and overall survival (OS).RESULTS:The in-hospital postoperative mortality and morbidity rates were 8.4 and 34.7%, respectively. Squamous cell histology (p = 0.040) and radiation dose ≥ 55 Gy (p = 0.047) were independently associated with major morbidity. The AL rate was 12.7%, and cervical anastomosis was independently associated with AL (p = 0.002). OS at 5 years was 34.0%. Radiation dose ≥ 55 Gy (p = 0.003), occurrence of postoperative complications (p = 0.006), ypTNM stage 3 (p = 0.019), and positive surgical margins (p < 0.001) were linked to poor prognosis.CONCLUSIONS:SALV is a valuable option for patients with persistent or recurrent disease after dCRT and offers long-term survival. Factors such as radiation dose and anastomosis location identified here will help to optimize outcomes after SALV, which may be considered a standard treatment in the EC therapeutic armamentarium

Second primary malignancies in patients treated for gastric mucosa-associated lymphoid tissue lymphoma.

IF 2.755International audienceTo assess the risk of second primary malignancy (SPM) in patients with gastric mucosa-associated lymphoid tissue (MALT) Lymphoma (GML), we included 175 patients with GML in the present study. The incidence of SPM in the general population, used for reference, was determined from the French network of cancer registries. During the 1442.9 patient-years of follow-up, 29 patients were diagnosed with incident SPM, including five patients diagnosed with gastric cancer (20.1/1000 patient-years). An increased incidence of SPM was observed in patients with GML (standardized incidence ratios [SIR]: 1.71 [1.14-2.45]) compared to the general French population especially for gastric cancer (SIR: 16.1 [5.19-37.56]). This elevated risk of SPM was significantly increased only in patients treated with immuno/chemotherapy but not in patients treated with Helicobacter pylori eradication alone. Long-term follow-up of patients with GML is mandatory even in patients who have achieved complete remission

A new SARS-CoV-2 variant poorly detected by RT-PCR on nasopharyngeal samples, with high lethality: an observational study

International audienceObjectives - In early January 2021 an outbreak of nosocomial cases of coronavirus disease 2019 (COVID-19) emerged in Western France; RT-PCR tests were repeatedly negative on nasopharyngeal samples but positive on lower respiratory tract samples. Whole-genome sequencing (WGS) revealed a new variant, currently defining a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) lineage B.1.616. In March, the WHO classified this as a 'variant under investigation' (VUI). We analysed the characteristics and outcomes of COVID-19 cases related to this new variant. Methods - Clinical, virological, and radiological data were retrospectively collected from medical charts in the two hospitals involved. We enrolled those inpatients with: (a) positive SARS-CoV-2 RT-PCR on a respiratory sample, (b) seroconversion with anti-SARS-CoV-2 IgG/IgM, or (c) suggestive symptoms and typical features of COVID-19 on a chest CT scan. Cases were categorized as B.1.616, a variant of concern (VOC), or unknown. Results - From 1st January to 24th March 2021, 114 patients fulfilled the inclusion criteria: B.1.616 (n = 39), VOC (n = 32), and unknown (n = 43). B.1.616-related cases were older than VOC-related cases (81 years, interquartile range (IQR) 73-88 versus 73 years, IQR 67-82, p < 0.05) and their first RT-PCR tests were rarely positive (6/39, 15% versus 31/32, 97%, p < 0.05). The B.1.616 variant was independently associated with severe disease (multivariable Cox model HR 4.0, 95%CI 1.5-10.9) and increased lethality (28-day mortality 18/39 (46%) for B.1.616 versus 5/32 (16%) for VOC, p = 0.006). Conclusion - We report a nosocomial outbreak of COVID-19 cases related to a new variant, B.1.616, which is poorly detected by RT-PCR on nasopharyngeal samples and is associated with high lethality

Effectiveness and Safety of Vedolizumab Induction Therapy for Patients with Inflammatory Bowel Disease

International audienceBackground & aims - Phase 3 trials have shown the efficacy of vedolizumab, which binds to integrin α4β7, in patients with Crohn's disease (CD) or ulcerative colitis (UC). We investigated the effectiveness and safety of vedolizumab in patients who failed anti-tumor necrosis factor therapy. Methods - From June through December 2014, there were 173 patients with CD and 121 patients with UC who were included in a multicenter nominative compassionate early access program granted by French regulatory agencies. This program provided patients with access to vedolizumab before it was authorized for marketing. Vedolizumab (300 mg) was administered intravenously at weeks 0, 2, and 6, and then every 8 weeks. Disease activity was assessed using the Harvey-Bradshaw Index for CD and the partial Mayo Clinic score for UC. We report results obtained after the 14-week induction phase. Results - Among the 294 patients treated with vedolizumab (mean age, 39.5 ± 14.0 y; mean disease duration, 10.8 ± 7.6 y; concomitant steroids, 44% of cases), 276 completed the induction period, however, 18 discontinued vedolizumab because of a lack of response (n = 14), infusion-related reaction (n = 2), or infections (n = 2). At week 14, 31% of patients with CD were in steroid-free clinical remission and 51% had a response; among patients with UC, 36% were in steroid-free clinical remission and 50% had a response. No deaths were reported. Severe adverse events occurred in 24 patients (8.2%), including 15 (5.1%) that led to vedolizumab discontinuation (1 case of pulmonary tuberculosis and 1 rectal adenocarcinoma). Conclusions - In a cohort of patients with CD or UC who failed previous anti-tumor necrosis factor therapy, approximately one third of patients achieved steroid-free clinical remission after 14 weeks of induction therapy with vedolizumab. This agent had an acceptable safety profile in these patients
