Organ sparing to cure stage IV rectal cancer: A case report and review of literature.

BACKGROUND: Rectal sparing is an option for some rectal cancers with complete or good response after chemoradiotherapy (CRT); however, it has never been evaluated in patients with metastases. We assessed long-term outcomes of a rectal-sparing approach in a liver-first strategy for patients with rectal cancer with resectable liver metastases. CASE SUMMARY: We examined patients who underwent an organ-sparing approach for rectal cancer with synchronous liver metastases using a liver-first strategy during 2010-2015 (n = 8). Patients received primary chemotherapy and pelvic CRT. Liver surgery was performed during the interval between CRT completion and rectal tumor re-evaluation. Clinical and oncological characteristics and long-term outcomes were assessed.All patients underwent liver metastatic resection with curative intent. The R0 rate was 100%. Six and two patients underwent local excision and a watch-and-wait (WW) approach, respectively. All patients had T3N1 tumors at diagnosis and had good clinical response after CRT. The median survival time was 60 (range, 14-127) mo. Three patients were disease free for 5, 8, and 10 years after the procedure. Five patients developed metastatic recurrence in the liver (n = 5) and/or lungs (n = 2). Only one patient developed local recurrence concurrent with metastatic recurrence 24 mo after the WW approach. Two patients died during follow-up. CONCLUSION: The results suggest good local control in patients undergoing organ-sparing strategies for rectal cancer with synchronous liver metastasis. Prospective trials are required to validate these data and identify good candidates for these strategies.

Local excision after neoadjuvant chemoradiotherapy for mid and low rectal cancer: a multicentric French study from the GRECCAR group.

AIM: A complete or subcomplete tumour response (CTR) is observed in 10%-25% of patients with mid/low rectal cancer after neoadjuvant chemoradiotherapy (CRT). The aim of our study was to report a multicentric French experience in local excision (LE) after CRT. METHOD: All patients who underwent LE for mid/low rectal cancer with suspected CTR after CRT, from 2006 to 2019 in seven GRECCAR centres were included. LE was considered adequate if the specimen showed a ypT0/Tis/T1R0 tumour, otherwise, a completion total mesorectal excision (TME) was discussed. Morbi-mortality, functional results and oncological outcomes were studied. RESULTS: A total of 257 patients were included. LE specimens showed 36% ypT0, 4% ypTis and 19% ypT1. Thus, 108 patients (42%) had theoretical indication of completion TME, which was performed in only 42 patients. Overall, 30-day morbidity after LE was 11%, including 2% Clavien-Dindo grade III or IV complications. After completion TME, 47% described major low anterior resection syndrome versus 5% after LE alone (p < 0.001). After a mean follow-up of 4 years (range 2-6 years), the recurrence rate was 11% after LE, 32% after completion TME and 20% in patients for whom completion TME was indicated but not performed (p = 0.021). CONCLUSION: TME remains the gold standard for mid/low rectal cancer after CRT. LE in selected patients is safe for operative and functional, but also oncological, results. However, completion TME was indicated in 42% of patients after LE, highlighting the difficulty of the preoperative diagnosis of CTR after CRT.

Piecemeal Resection for Large Colorectal Adenomas Remains Essential in 2022: A Single-Center Experience in a Tertiary French Center.

BACKGROUND AND AIMS: Colorectal lesions measuring greater than 20 mm are unsuitable for en bloc endoscopic mucosal resection (EMR): piecemeal EMR (PM-EMR) and endoscopic submucosal dissection (ESD) are needed. The European Society of Gastrointestinal Endoscopy (ESGE) recommends ESD only for microinfiltrative lesions, although Japanese teams perform en bloc ESD for all lesions. We report the outcomes obtained in our endoscopy unit for these lesions and assess the hybrid "knife-assisted piecemeal EMR" (KAPM-EMR) technique. The main aim was to assess the short-term outcomes (C1). The secondary objectives were to evaluate the long-term results (C2), adverse event rate and management of recurrence. METHODS: We retrospectively analyzed data from patients treated by PM-EMR, KAPM-EMR and ESD for a colorectal lesion measuring greater than 20 millimeters using prospective inclusion over four years. RESULTS: Data from 167 patients (median age: 70) with a median follow-up of 15.1 months were analyzed after excluding 95 patients. A total of 131 lesions were removed by PM-EMR, 24 by KAPM-EMR and 12 by ESD; 146/167 (87.4%) patients were considered in remission at C1. Recurrence was treated by endoscopy in 20/21 patients (95%); 86/89 (96.6%) were in remission at C2. A total of 16/167 patients developed adverse events, all of whom except one were endoscopically managed. KAPM-EMR was associated with a higher perforation risk (p=0.037). No differences in postoperative bleeding were found among the three groups (p=0.576). CONCLUSIONS: Piecemeal resection remains an effective and safe technique for large colorectal adenomas. KAPM-EMR may be useful but should be applied with caution due to the risk of perforation.

Is Delaying a Coloanal Anastomosis the Ideal Solution for Rectal Surgery?: Analysis of a Multicentric Cohort of 564 Patients From the GRECCAR.

OBJECTIVES: To assess the specific results of delayed coloanal anastomosis (DCAA) in light of its 2 main indications. BACKGROUND: DCAA can be proposed either immediately after a low anterior resection (primary DCAA) or after the failure of a primary pelvic surgery as a salvage procedure (salvage DCAA). METHODS: All patients who underwent DCAA intervention at 30 GRECCAR-affiliated hospitals between 2010 and 2021 were retrospectively included. RESULTS: Five hundred sixty-four patients (male: 63%; median age: 62 years; interquartile range: 53-69) underwent a DCAA: 66% for primary DCAA and 34% for salvage DCAA. Overall morbidity, major morbidity, and mortality were 57%, 30%, and 1.1%, respectively, without any significant differences between primary DCAA and salvage DCAA ( P = 0.933; P = 0.238, and P = 0.410, respectively). Anastomotic leakage was more frequent after salvage DCAA (23%) than after primary DCAA (15%), ( P = 0.016).Fifty-five patients (10%) developed necrosis of the intra-abdominal colon. In multivariate analysis, intra-abdominal colon necrosis was significantly associated with male sex [odds ratio (OR) = 2.67 95% CI: 1.22-6.49; P = 0.020], body mass index >25 (OR = 2.78 95% CI: 1.37-6.00; P = 0.006), and peripheral artery disease (OR = 4.68 95% CI: 1.12-19.1; P = 0.030). The occurrence of this complication was similar between primary DCAA (11%) and salvage DCAA (8%), ( P = 0.289).Preservation of bowel continuity was reached 3 years after DCAA in 74% of the cohort (primary DCAA: 77% vs salvage DCAA: 68%, P = 0.031). Among patients with a DCAA mannered without diverting stoma, 75% (301/403) have never required a stoma at the last follow-up. CONCLUSIONS: DCAA makes it possible to definitively avoid a stoma in 75% of patients when mannered initially without a stoma and to save bowel continuity in 68% of the patients in the setting of failure of primary pelvic surgery.

Intracorporeal Anastomosis and ERAS Program: The Winning Combination of Optimized Postoperative Outcomes After Laparoscopic Right Colectomy.

BACKGROUND: Laparoscopic technique and the enhanced recovery after surgery (ERAS) protocol have become the standard of care in patients undergoing right colon cancer surgery, reducing hospital stay and postoperative morbidity. However, the optimal anastomosis technique [intracorporeal anastomosis (ICA) or extracorporeal anastomosis (ECA)] remains debated. This study aimed to determine the optimal perioperative approach (ICA vs. ECA combined with the ERAS program vs. standard care) for patients undergoing laparoscopic right colectomy for cancer. MATERIALS AND METHODS: This single-center, retrospective study evaluated all consecutive patients who underwent laparoscopic right hemicolectomy for cancer between January 2012 and June 2021. Patient data were analyzed in 4 treatment groups according to the type of anastomosis and the care protocol. The primary endpoint was total postoperative hospital stay (THS). The secondary endpoints were recovery time and overall morbidity rate. RESULTS: The baseline characteristics of the 373 included patients were comparable between the 4 groups. THS was significantly shorter in the ICA/ERAS group than in the ECA/standard and ICA/standard groups ( P <0.01), but there was no significant difference between the ICA/ERAS and ECA/ERAS groups (5.7 vs. 6.4 d; P =0.17). Recovery time was significantly shorter in the ICA/ERAS group ( P <0.01). The overall morbidity rate, including anastomotic morbidity, was comparable among the 4 groups. Regression analysis showed that ICA and the ERAS program were both predictive factors to reduce the THS and recovery time. CONCLUSIONS: ICA combined with the ERAS program achieves the best outcomes and thus seems to be the optimal approach for the management of patients undergoing laparoscopic right colectomy for cancer.

The impact of brachytherapy boost for anal canal cancers in the era of de-escalation treatments.

PURPOSE: To analyze clinical outcomes of high-dose-rate (HDR) interstitial brachytherapy boost (ISBT) after external beam radiation therapy (EBRT) or chemoradiotherapy (CRT) for the treatment of anal canal cancers (ACC). METHODS AND MATERIALS: A total of 78 patients with ACC were treated at our institution by ISBT. Local Control (LC), disease-free survival (DFS), overall survival (OS), colostomy-free survival (CFS) and toxicity rates were analyzed. RESULTS: With a median followup (FU) of 59.8 months (95% CI [55.8-64.2]), six (7.7%) local recurrences with 2 patients (2.6%) having persistent disease at 3 months were observed. The 5-year rate of LC for the entire population was 92% [83-96%]. The 5-year DFS rate was 86% [76-93%]. The 5-year OS was 96% [88-99%]. In the univariate analysis, chemotherapy was significantly associated with morbidity grade ≥2. Late digestive toxicity grade ≥3 was reported in 8.9% patients, 1 patient underwent colostomy due to toxicity. The 5-year CFS rate was 88% [79-94%]. CONCLUSIONS: HDR interstitial brachytherapy boost provide excellent rates of tumor control and colostomy-free survival with a favorable profile of GI toxicity. Continence in anal cancer survivors is a challenge and the boost technique must be discussed in a multidisciplinary approach as part of de-escalation treatments.

An optimised liver-first strategy for synchronous metastatic rectal cancer leads to higher protocol completion and lower surgical morbidity.

INTRODUCTION: The optimal management of rectal cancer with synchronous liver metastases remains debatable. Thus, we propose an optimised liver-first (OLF) strategy that combines concomitant pelvic irradiation with hepatic management. This study aimed to evaluate the feasibility and oncological quality of the OLF strategy. MATERIALS AND METHODS: Patients underwent systemic neoadjuvant chemotherapy followed by preoperative radiotherapy. Liver resection was performed in one step (between radiotherapy and rectal surgery) or in two steps (before and after radiotherapy). The data were collected prospectively and analysed retrospectively as intent to treat. RESULTS: Between 2008 and 2018, 24 patients underwent the OLF strategy. The rate of treatment completion was 87.5%. Three patients (12.5%) did not proceed to the planned second-stage liver and rectal surgery because of progressive disease. The postoperative mortality rate was 0%, and the overall morbidity rates after liver and rectal surgeries were 21% and 28.6%, respectively. Only two patients developed severe complications. Liver and rectal complete resection was performed in 100% and 84.6%, respectively. A rectal-sparing strategy was performed in 6 patients who underwent local excision (n = 4) or a watch and wait strategy (n = 2). Among patients who completed treatment, the median overall and disease-free survivals were 60 months (range 12-139 months) and 40 months (range 10-139 months), respectively. Eleven patients (47.6%) developed recurrence, among whom five underwent further treatment with curative intent. CONCLUSION: The OLF approach is feasible, relevant, and safe. Organ preservation was feasible for a quarter of patients and may be associated with reduced morbidity.

Supine bottom-up extralevator abdominoperineal excision for anorectal adenocarcinoma is not inferior to standard approach and may be thus safely performed.

BACKGROUND: Extralevator abdominoperineal excision (APE) for rectal carcinoma has been described in order to improve pathological and oncological results compared to standard APE. To obtain the same oncological advantages as extralevator APE, we have previously described a new procedure starting by a perineal approach: the supine bottom-up APE. Our objective is to compare oncological and surgical outcomes between the supine bottom-up APE and the standard APE. METHODS: All patients with low rectal adenocarcinoma requiring APE were retrospectively included and divided into 2 groups: supine bottom-up APE (Group A) and standard APE (Group B). RESULTS: From 2008 to 2016, 61 patients were divided into Groups A (n = 30) and B (n = 31). Postoperative outcomes and median length of stay were similar between groups. Patients from Group A had a significantly longer distal margin (30 [8-120] vs. 20 [1.5-60] mm, p = 0.04) and higher number of harvested lymph nodes (14.5 [0-33] vs. 11 [5-25], p = 0.03) than those from Group B. Circumferential resection margin involvement was similar between groups (28 vs. 22%, p = 0.6), whereas tumors from Group A were significantly larger and more frequently classified as T4 than those from Group B. Operative time was significantly shorter in Group A (437.5 [285-655] minutes) than in Group B (537.5 [361-721] minutes, p = 0.0009). At the end of follow-up, local recurrence occurred in 7 and 16% of patients from Groups A and B (p = 0.68). Three-year overall and disease-free survival rates were similar between groups (87 vs. 90%, p = 0.62 and 61 vs. 63%, p = 0.88, respectively). CONCLUSION: Our findings suggest that supine bottom-up APE doesn't impair surgical outcomes, pathological results, overall and disease-free survivals in comparison with standard APE. This new procedure may be thus safely performed and decrease the operative time. Further randomized multicentric studies are required to confirm these results.

Blood, Cellular, and Tissular Calcineurin Inhibitors Pharmacokinetic-Pharmacodynamic Relationship in Heart Transplant Recipients: The INTRACAR Study.

BACKGROUND: After heart transplantation, calcineurin inhibitors (CNI) (cyclosporin A and tacrolimus) are key immunosuppressive drugs to prevent graft rejection. Whole-blood concentration (C blood )-guided therapeutic drug monitoring (TDM) is systematically performed to improve graft outcomes. However, some patients will still experience graft rejection and/or adverse events despite CNI C blood within the therapeutic range. Other pharmacokinetic parameters, such as the intragraft, or intracellular concentration at the CNI site of action could refine their TDM. Nonetheless, these remain to be explored. The objective of the INTRACAR study was to describe the relationship between whole blood, intragraft, and intracellular CNI concentrations as well as their efficacy in heart transplant recipients (HTR). METHODS: In a cohort of HTR, protocol endomyocardial biopsies (EMB) were collected to assess rejection by anatomopathological analysis. Part of the EMB was used to measure the intragraft concentrations of CNI (C EMB ). C blood and the concentration inside peripheral blood mononuclear cells, (C PBMC ), a cellular fraction enriched with lymphocytes, were also monitored. Concentrations in the 3 matrices were compared between patients with and without biopsy-proven acute rejection (BPAR). RESULTS: Thirty-four HTR were included, representing nearly 100 pharmacokinetic (PK) samples for each CNI. C blood , C EMB , and C PBMC correlated for both CNI. BPAR was observed in 74 biopsies (39.6%) from 26 patients (76.5%), all except one was of low grade. None of the PK parameters (C blood , C EMB , C PBMC , C EMB/blood , and C PBMC/blood ) was associated with BPAR. CONCLUSIONS: In this cohort of well-immunosuppressed patients, no association was observed for any of the PK parameters, including C blood , with the occurrence of BPAR. However, a trend was noticed for the C EMB and C EMB/blood of cyclosporin A. Further studies in higher-risk patients may help optimize the use of C EMB and C PBMC for CNI TDM in HTR.

Nomogram to predict disease recurrence in patients with locally advanced rectal cancer undergoing rectal surgery after neoadjuvant therapy: retrospective cohort study.

INTRODUCTION: Prognostic models can be used for predicting survival outcomes and guiding patient management. TNM staging alone is insufficient for predicting recurrence after chemoradiotherapy (CRT) and surgery for locally advanced rectal cancer. This study aimed to develop a nomogram to better predict cancer recurrence after CRT followed by total mesorectal excision (TME) and tailor postoperative management and follow-up. MATERIALS AND METHODS: Between 2002 and 2019, data were retrospectively collected on patients with rectal adenocarcinoma. Data on sex, age, carcinoembryonic antigen (CEA) level, tumour location, induction chemotherapy, adjuvant chemotherapy, tumour downsizing, perineural invasion, lymphovascular invasion, pathological stage, resection margins (R0 versus R1), and pelvic septic complications were analysed. The variables significantly associated with cancer recurrence were used to build a nomogram that was validated in both the training and validation cohorts. Model performance was evaluated by receiver operating characteristic curve and area under the curve (AUC) analyses. RESULTS: After applying exclusion criteria, 634 patients with rectal adenocarcinoma were included in this study. Eight factors (CEA level, adjuvant chemotherapy, tumour downsizing, perineural invasion, lymphovascular invasion, pathological stage, resection margins (R0 versus R1), and pelvic septic complications) were identified as nomogram variables. Our nomogram showed good performance with an AUC of 0.74 and 0.75 in the training and validation cohorts respectively. CONCLUSION: Our nomogram is a simple tool for predicting cancer recurrence in patients with locally advanced rectal cancer after neoadjuvant CRT followed by TME. It provides an individual risk prediction of recurrence to tailor surveillance.

Case-Matched Comparison of Functional and Quality of Life Outcomes of Local Excision and Total Mesorectal Excision Following Chemoradiotherapy for Rectal Cancer.

BACKGROUND: Neoadjuvant chemoradiotherapy followed by radical surgery is the standard curative treatment for mid- to low-rectal cancer. However, the combination of these treatments may affect patients' GI and genitourinary functions and their quality of life. In the cases of good clinical response to neoadjuvant treatment, local excision is a rectal sparing strategy that would limit these side effects. OBJECTIVE: The aim of this study is to compare the effects of local excision or conventional laparoscopic total mesorectal excision after chemoradiotherapy in patients with rectal cancer. DESIGN: The design is a retrospective study. SETTING: The setting used is a single tertiary center. PATIENTS: Patients with mid- to low-rectal cancer treated with chemoradiotherapy and accessible via conservative surgery at our hospital between January 2010 and December 2018 were included. Patients undergoing local excision were matched 1 to 1 with the patients undergoing total mesorectal excision by age, sex, body mass index, tumor height, and year of surgery. MAIN OUTCOME MEASURES: Quality of life and digestive and genitourinary functions were measured using validated questionnaires. The socioeconomic impact was also assessed. RESULTS: Forty-four patients undergoing local excision agreed to participate and were matched with 44 patients undergoing total mesorectal excision. Patients who underwent local excision reported a more favorable global health status ( p < 0.01), emotional function ( p = 0.035), social function ( p = 0.04), and body image ( p = 0.04). The low anterior resection syndrome score (rate of major syndrome, 23.8% vs 54.5%; p < 0.01) and the specific fecal incontinence subscale score ( p < 0.01) were more favorable in the local excision group. Sexual and urinary outcomes were comparable between the 2 groups. Local excision had a lower impact on the professional status (35.7% vs 76.5%; p = 0.03). LIMITATIONS: The study limitations include its retrospective design and small sample size. CONCLUSIONS: When indicated, local excision improves the bowel function and quality of life of patients undergoing surgery for rectal cancer after chemoradiotherapy compared with total mesorectal excision.

También se evaluó el impacto socioeconómico.RESULTADOS:Cuarenta y cuatro pacientes sometidos a escisión local aceptaron participar y fueron emparejados con 44 pacientes sometidos a escisión mesorrectal total. Los pacientes que se sometieron a escisión local informaron un estado de salud global más favorable ( p <0,01), función emocional ( p = 0,035), función social ( p = 0,04) e imagen corporal ( p = 0,04). La puntuación baja del síndrome de resección anterior (tasa de síndrome mayor: 23,8 % frente a 54,5 %; p <0,01) y la puntuación de la subescala de incontinencia fecal específica ( p <0,01) fueron más favorables en el grupo de escisión local. Los resultados sexuales y urinarios fueron comparables entre los dos grupos. La escisión local tuvo un menor impacto en el estatus profesional (35,7% vs 76,5%; p = 0,03).LIMITACIONES:Diseño retrospectivo, tamaño de muestra pequeño.CONCLUSIONES:Cuando está indicada, la escisión local mejora la función intestinal y la calidad de vida de los pacientes sometidos a cirugía por cáncer de recto después de quimiorradioterapia en comparación con escisión total de mesorecto.

Impact of fast-track care program in laparoscopic rectal cancer surgery: a cohort-comparative study.

BACKGROUND: Fast-track care programs after surgery improve recovery and decrease the length of hospital stay and postoperative morbidity in colonic cancer. However, the true impact of these programs on morbidity rates after rectal cancer surgery remains unclear. We aimed to assess the feasibility and impact of the fast-track program on postoperative outcomes after restorative laparoscopic rectal cancer resection and temporary loop ileostomy. METHODS: This single-center observational study assessed data of patients undergoing elective rectal cancer surgery during a defined period before (standard group) and after the introduction of a fast-track program (fast-track group) from a prospectively maintained database. The primary endpoint was postoperative 90-day morbidity. Secondary endpoints were 30-day morbidity, fast-track program compliance, length of hospital stay, and readmission rate. RESULTS: Overall, 336 patients (n = 176, standard group; n = 160, fast-track group) were assessed; there was no significant between-group difference in the patients' baseline characteristics (age, sex, body mass index, comorbidities, or neoadjuvant treatment). The protocol compliance rate was 91.4% in the fast-track group. The 90-day morbidity and mean total length of hospital stay were significantly lower in the fast-track group than in the standard group (34% vs 49%, respectively, p < 0.01 and 8.96 days vs 10.2 days, p < 0.01, respectively). There was no difference in readmission rates. Multivariate analysis revealed the fast-track program to be the only predictive factor of postoperative morbidity. CONCLUSION: Fast-track programs can be safely implemented following rectal cancer surgery to reduce the overall morbidity rate and length of hospital stay without adversely increasing the readmission rate.

Tailored Strategy for Locally Advanced Rectal Carcinoma (GRECCAR 4): Long-term Results From a Multicenter, Randomized, Open-Label, Phase II Trial.

BACKGROUND: Systematic preoperative radiochemotherapy and total mesorectal excision are the standard of care for locally advanced rectal carcinoma. Some patients can be over- or undertreated. OBJECTIVE: This study aimed to investigate the long-term oncological, functional, and late morbidity outcomes after tailored radiochemotherapy and induction high-dose chemotherapy. DESIGN: This is a prospective, phase II, multicenter, open-label study at 16 tertiary centers in France. SETTINGS: Patients were operated on by surgeons from the French GRECCAR group. PATIENTS: Two hundred six patients were randomly assigned to treatment: good responders after chemotherapy (≥75% tumor volume reduction) to immediate surgery (arm A) or standard radiochemotherapy (capecitabine 50) plus surgery (arm B) and poor responders to capecitabine 50 (arm C) or intensive radiochemotherapy (capecitabine 60; 60 Gy irradiation; arm D) before surgery. INTERVENTIONS: Treatment was tailored according to MRI response to induction chemotherapy. RESULTS: After induction treatment, 194 patients were classified as good (n = 30, 15%) or poor (n = 164, 85%) responders; they were included in arms A and B (16 and 14 patients) or C and D (113 and 51 patients). The primary objective was obtained: R0 resection rates (90% CI) in the 4 arms were 100% (74-100), 100% (85-100), 83% (72-91), and 88% (77-95). At 5 years, overall survival rates were 90% (47.3-98.5), 93.3% (61.3-99.0), 84.3% (71.0-91.8), and 86.1% (71.6-93.5); disease-free survival rates were 80% (40.9-94.6), 89.5% (64.1-97.3), 72.9% (58.5-82.9), and 72.8% (57.7-83.2); local recurrence rates were 0%, 0%, 2.1% (0.3-13.9), and 9.3% (3.6-23.0); and metastasis rates were 20% (5.4-59.1), 10.5% (2.7-35.9), 18% (31.8-94.6), and 18.8% (10.2-33.0). Late morbidity and quality-of-life evaluations showed no significant difference between arms. LIMITATIONS: Limitations were due to the small number of patients randomly assigned in the good responder arms, especially arm A without radiotherapy. CONCLUSION: Tailoring preoperative radiochemotherapy based on induction treatment response appears to be promising. Future prospective trials should confirm this strategy.

Se alcanzó el objetivo principal: las tasas de resección R0 [intervalo de confianza del 90%] en los cuatro brazos respectivamente, fueron del 100% [74-100], 100% [85-100], 83% [72-91] y 88% [77-95]. A los 5 años, las tasas fueron: de sobrevida global 90% [47,3-98,5], 93,3% [61,3-99,0], 84,3% [71,0-91,8], 86,1% [71,6-93,5]; de sobrevida libre a la enfermedad 80% [40,9-94,6], 89,5% [64,1-97,3], 72,9% [58,5-82,9], 72,8% [57,7-83,2]; de recidiva local 0, 0, 2,1% [0,3-13,9], 9,3% [3,6-23,0]; de metástasis 20% [5,4-59,1], 10,5% [2,7-35,9], 18% [31,8-94,6], 18,8% [10,2-33,0]. La evaluación tardía de la morbilidad y la calidad de vida no mostraron diferencias significativas entre los brazos.LIMITACIONES:Debido al pequeño número de pacientes asignados al azar en los brazos de buenos respondedores, especialmente en el brazo A de aquellos sin radioterapia.CONCLUSIÓN:Parecería muy prometedor el adaptar la radio-quimioterapia pré-operatoria basada en la respuesta al tratamiento de inducción. Estudios prospectivos en el futuro podrán confirmar la presente estrategia. Consulte Video Resumen en http://links.lww.com/DCR/B761 .

Early and Long-Term Outcomes after Direct Bridge-to-Transplantation with Extracorporeal Membrane Oxygenation.

BACKGROUND: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) as direct bridge-to-transplantation (dBTT) remains controversial. We compared the short- and long-term outcomes of adult patients undergoing urgent heart transplantation (HT) with (dBTT) and without (non-BTT) VA-ECMO support at the time of HT. METHODS: Adults who underwent urgent HT in two institutions were assessed (N = 133; dBTT: N = 34 and non-BTT: N = 99). Patient characteristics, donor characteristics, in-hospital outcomes, and overall survival were compared. Mean follow up was 77±38 months and was 100% complete. Mortality predictors were identified using univariate and multivariate analyses. RESULTS: Before HT, patients with dBTT had higher rates of ischemic cardiomyopathy, acute kidney injury, liver failure, respiratory failure, and longer graft ischemia times. More patients in the dBTT group had complications, such as requiring VA-ECMO postoperatively (dBTT=50% vs. non-BTT=20%, P < 0.01). Hospital deaths (dBTT=23% vs. non-BTT=19%, P = 0.58), one-year (74% vs. 80%) and five-year survival (62% vs. 75%, P = 0.74 for overall survival) were not significantly different. The MELD-XI score and previous cardiac surgery were independent predictors of hospital mortality. CONCLUSION: Direct bridge-to-transplantation in patients on VA-ECMO support was not associated with worse long-term outcomes compared with non-VA-ECMO urgent HT, especially in recipients without any associated organ failure and a low MELD-XI score before HT.

Surgical Management of Retrorectal Tumors: A French Multicentric Experience of 270 Consecutives Cases.

OBJECTIVE: To report the largest multicentric experience on surgical management of retrorectal tumors (RRT). BACKGROUND: Literature data on RRT is limited. There is no consensus concerning the best surgical approach for the management of RRT. METHODS: Patients operated for RRT in 18 academic French centers were retrospectively included (2000-2019). RESULTS: A total of 270 patients were included. Surgery was performed through abdominal (n = 72, 27%), bottom (n = 190, 70%), or combined approach (n = 8, 3%). Abdominal approach was laparoscopic in 53/72 (74%) and bottom approach was Kraske modified procedures in 169/190 (89%) patients. In laparoscopic abdominal group, tumors were more frequently symptomatic (37/53, 70% vs 88/169, 52%, P = 0.02), larger [mean diameter = 60.5 ± 24 (range, 13-107) vs 51 ± 26 (20-105) mm, P = 0.02] and located above S3 vertebra (n = 3/42, 7% vs 0%, P = 0.001) than those from Kraske modified group. Laparoscopy was associated with a higher risk of postoperative ileus (n = 4/53, 7.5% vs 0%, P = 0.002) and rectal fistula (n = 3/53, 6% vs 0%, P=0.01) but less wound abscess (n = 1/53, 2% vs 24/169, 14%, P = 0.02) than Kraske modified procedures. RRT was malignant in 8%. After a mean follow up of 27 ±39 (1-221) months, local recurrence was noted in 8% of the patients. After surgery, chronic pain was observed in 17% of the patients without significant difference between the 2 groups (15/74, 20% vs 3/30, 10%; P = 0.3). CONCLUSIONS: Both laparoscopic and Kraske modified approaches can be used for surgical treatment of RRT (according to their location and their size), with similar long-term results.

Is percutaneous destruction of a solitary liver colorectal metastasis as effective as a resection?

BACKGROUNDS/AIMS: Surgical resection remains the gold standard in the treatment of colorectal liver metastasis. However, when a patient presents with a deep solitary colorectal liver metastasis (S-CLM), the balance between the hepatic volume sacrificed and the S-CLM volume is sometimes clearly unappropriated. Thus, alternatives to surgery, such as operative and percutaneous radiofrequency ablation (RFA) and microwave ablation (MWA), have been developed. This study aimed to identify the prognostic factors affecting survival of patients with S-CLM who undergo curative-intent liver resection or local destruction (RFA or MWA). METHODS: We retrospectively identified 211 patients with synchronous or metachronous S-CLM who underwent either surgical resection (n=182) or local destruction (RFA or MWA; n=29) according to the S-CLM size, location, and surrounding Glissonian structures. RESULTS: Patients who underwent RFA or MWA had S-CLM of a smaller size than those who underwent resection (mean 19.7 vs. 37.3 mm, p<.01). The 1-, 3-, and 5-year overall survival (OS) rates were 97.4%, 84.9%, and 74.9%, respectively. The 1-, 3-, and 5-year disease-free survival (DFS) rates were 77.9%, 47%, and 38.9%, respectively. S-CLM located in the left liver (p=.04), S-CLM KRAS mutation (p<.01), and extra-hepatic recurrence (p<.01) were identified as independent poor risk factors for overall survival (OS); the OS and DFS were comparable in patients with surgical procedure or percutaneous MWA. CONCLUSIONS: In eligible S-CLM cases, percutaneous MWA seems to be as oncologically efficient as surgical resection and should be include in the decision-tree for treatment strategies.

Successful heart transplantation for COVID-19-associated post-infectious fulminant myocarditis.

Various clinical presentations of the 2019 coronavirus disease (COVID-19) have been described, including post-infectious acute and fulminant myocarditis. Here, we describe the case of a young patient admitted for COVID-19-associated post-infectious fulminant myocarditis. Despite optimal pharmacologic management, haemodynamic status worsened requiring support by veno-arterial extracorporeal membrane oxygenation. Emergent heart transplantation was required at Day 11 given the absence of cardiac function improvement. The diagnosis of post-infectious COVID-19-associated myocarditis was made from both pathologic examination of the explanted heart and positive SARS-CoV-2 serology.

Systematic Early Urinary Catheter Removal Integrated in the Full Enhanced Recovery After Surgery (ERAS) Protocol After Laparoscopic Mid to Lower Rectal Cancer Excision: A Feasibility Study.

PURPOSE: Enhanced Recovery After Surgery (ERAS) programs advocate early urinary catheter removal after rectal cancer surgery; however, the optimal duration remains unclear. This study assessed the feasibility of the early urinary catheter removal protocol after rectal cancer surgery within an ERAS pathway and identified predictive factors for failure of this strategy. METHODS: Between March 2017 and October 2018, all unselected and consecutive patients who underwent rectal cancer resection and benefited from our ERAS program were included. Urinary complications (infection and retention) were prospectively recorded. Success was defined as catheter removal on postoperative day (POD) 3 without urinary complications. RESULTS: Of 135 patients (male, 63.7%; neoadjuvant chemoradiation, 57.0%; urology history, 17.8%), 120 had early urinary catheter removal with no complications (success rate, 88.9%), 8 did not have urinary catheter removal on POD 3 due to clinical judgment or prescription error, 5 experienced a urinary tract infection, and 2 had acute urinary retention. Obesity (odds ratio [OR], 0.16; P = 0.003), American Society of Anesthesiologists physical status classification > II (OR, 0.28; P = 0.048), antiaggregant platelet medication (OR, 0.12; P < 0.001), absence of anastomosis (OR, 0.1; P = 0.003), and prolonged operative time (OR, 0.21; P = 0.020) were predictive factors for failure. Conversely, optimal compliance with the ERAS program (OR, 7.68; P < 0.001), postoperative nonsteroidal anti-inflammatory drug use (OR, 21.71; P < 0.001), and balanced intravenous fluid therapy (OR, 7.87; P = 0.001) were associated with increased strategy success. CONCLUSION: Withdrawal of the urinary catheter on POD 3 was successfully achieved after laparoscopic rectal resection and can be safely implemented in the ERAS program.
