Impact of neoadjuvant chemoradiation on lymph node status in esophageal cancer: post hoc analysis of a randomized controlled trial.

OBJECTIVE: The study objectives were to analyze the impact of the number of lymph nodes (LNs) reported as resected (NLNr) and the number of LNs invaded (NLNi) on the prognosis of esophageal cancer (EC) after neoadjuvant chemoradiotherapy. BACKGROUND: Pathological LN status is a major disease prognostic factor and marker of surgical quality. The impact of neoadjuvant chemoradiation (nCRT) on LN status remains poorly studied in EC. METHODS: Post hoc analysis from a phase III randomized controlled trial comparing nCRT and surgery (group nCRT) to surgery alone (group S) in stage I and II EC (NCT00047112). Only patients who underwent surgical resection were considered (n = 170). RESULTS: nCRT resulted in tumoral downstaging (pT0, 40.7% vs 1.1%, P < 0.001), LN downstaging (pN0, 69.1% vs 47.2%, P = 0.016), and reduction in the median NLNr [16.0 (range, 0-47.0) vs 22.0 (range, 3.0-58.0), P = 0.001] and NLNi [0 (range, 0-25) vs 1.0 (range, 0-25), P = 0.001]. A good histological response (TRG1/2) in the resected esophageal specimen correlated with reduced median NLNi [0 (range, 0-10) vs 1.0 (range, 0-4), P = 0.007]. After adjustment by treatment, NLNi [hazards ratio (HR) (1-3 vs 0) 3.5, 95% confidence interval (CI): 2.3-5.5, and HR (>3 vs 0) 3.5, 95% CI: 2.0-6.2, P < 0.001] correlated with prognosis, whereas NLNr [HR (<15 vs ≥15) 0.95, 95% CI: 0.6-1.4, P = 0.807 and HR (<23 vs ≥23) 1.4, 95% CI: 0.9-2.0, P = 0.131] did not. In Poisson regression analysis, nCRT was an independent predictive variable for reduced NLNr [exp(coefficient) 0.80, 95% CI: 0.66-0.96, P = 0.018]. CONCLUSIONS: nCRT is not only responsible for disease downstaging but also predicts fewer LNs being identified after surgical resection for EC. This has implications for the current quality criteria for surgical resection.

[Does early signet ring cell gastric carcinoma carry a worse prognosis?]. / Tumeurs adénocarcinomateuses superficielles de l'estomac: un contingent majoritaire à cellules indépendantes est-il associé à un mauvais pronostic?

INTRODUCTION: The signet ring cell (SRC) histological subtype is a factor of poor prognosis in advanced gastric adenocarcinomas, but its prognostic value in early gastric cancer is unclear. The aim of this study was to evaluate the prognostic impact of SRC in superficial gastric adenocarcinomas, based on a comparison of patients with SRC and non SRC histologies. PATIENTS AND METHODS: From a large national cohort of 3,010 patients operated on for gastric adenocarcinoma between January 1997 and January 2010, we selected patients with pTis or pT1 tumors and compared those with SRC and non SRC histology on the basis of demographic, surgical and histologic factors and outcomes. The primary endpoint was the 3-year survival rate. RESULTS: Among 421 patients with a pTis or pT1 tumor, 104 (24.7%) had the SRC subtype and 317 (75.3%) a non SRC subtype. Median age was significantly lower in the SRC group than in the non SRC group (59.6 vs 68.8 years, p<0.001). Other demographic variables were similar in the two groups. Extensive surgical resection was more frequent in the non SRC group (31.9% vs 12.5%, p<0.001), but R0 resection rates were similar (97.5% vs 98.1%, p=0.900). The submucosa was more frequently involved in the SRC group (94.2% vs 84.9%, p=0.043), while lymph node involvement and the number of invaded nodes were similar in the two groups. Recurrences (5.8% vs 8.8%, p=0.223) and sites of recurrence (especially peritoneal carcinomatosis, 1.9% vs 1.6% ; p=0.838) were similar in the two groups. The 3-year survival rate was similar in the SRC and non SRC groups (94.1% vs 89.9%, p=0. 403), although the median survival time had not been reached CONCLUSION: SRC is not a prognostic factor in superficial gastric adenocarcinoma.

Is pretreatment endoscopic biopsy a good predictor of signet ring cell histology in gastric carcinoma?

BACKGROUND: Signet ring cell (SRC) carcinoma is defined as an adenocarcinoma in which >50% of the total operative specimen consists of isolated or small groups of malignant cells containing intracytoplasmic mucins (hSRCs). We previously demonstrated that hSRCs are a predictor of poor prognosis with specific tumoral characteristics suggesting the need for a dedicated therapeutic strategy before surgery. However diagnostic accuracy and prognostic value of SRCs on pretreatment biopsies (bSRCs) is unknown. The aim of the study was to determine if bSRCs can accurately predict hSRCs and survival. METHODS: A retrospective analysis was performed among 254 patients with an adenocarcinoma. We performed pretreatment endoscopic biopsies and histopathologic analysis of the surgical specimen. Pretreatment endoscopic biopsy results were compared with definitive pathologic results and were correlated with long-term survival. RESULTS: From 254 patients enrolled, 96 had bSRCs (37.8%), and 101 (39.8%) had hSRCs. Pretreatment biopsy results were correct in 89 of 101 patients with hSRC (sensitivity 88.1%) and in 146 of 153 with histologic non-SRCs (hNSRCs) (specificity 95.4%). The positive and negative predictive values for the biopsies were 92.7, and 92.4%, respectively, with an overall accuracy of 92.5%. When compared to the biopsy results, non-SRCs (bNSRCs), bSRCs were associated with poorer survival and were identified as an independent factor for poor prognosis (hazard ratio 1.89 with 95% confidence interval 1.35 to 2.64, P < 0.001). CONCLUSIONS: The presence of signet ring cells in samples obtained from routine pretreatment endoscopic biopsies accurately predicts SRC histology and poor prognosis. The specific therapeutic strategy can consequently be considered from the initial diagnosis.

Oesophagogastric junction adenocarcinoma: which therapeutic approach?

Gastric and oesophageal cancers are among the leading causes of cancer-related death worldwide. By contrast with the decreasing prevalence of gastric cancer, incidence and prevalence of oesophagogastric junction adenocarcinoma (OGJA) are rising rapidly in developed countries. We provide an update about treatment strategies for resectable OGJA. Here we review findings from the latest randomised trials and meta-analyses, and propose guidelines regarding endoscopic, surgical, and perioperative treatments. Through a team approach, members from all diagnostic and therapeutic disciplines, such as gastroenterologists, surgeons, oncologists, radiologists, and radiotherapists, can effectively administer a range of treatment modalities.

Open versus laparoscopically-assisted oesophagectomy for cancer: a multicentre randomised controlled phase III trial - the MIRO trial.

BACKGROUND: Open transthoracic oesophagectomy is the standard treatment for infracarinal resectable oesophageal carcinomas, although it is associated with high mortality and morbidity rates of 2 to 10% and 30 to 50%, respectively, for both the abdominal and thoracic approaches. The worldwide popularity of laparoscopic techniques is based on promising results, including lower postoperative morbidity rates, which are related to the reduced postoperative trauma. We hypothesise that the laparoscopic abdominal approach (laparoscopic gastric mobilisation) in oesophageal cancer surgery will decrease the major postoperative complication rate due to the reduced surgical trauma. METHODS/DESIGN: The MIRO trial is an open, controlled, prospective, randomised multicentre phase III trial. Patients in study arm A will receive laparoscopic-assisted oesophagectomy, i.e., a transthoracic oesophagectomy with two-field lymphadenectomy and laparoscopic gastric mobilisation. Patients in study arm B will receive the same procedure, but with the conventional open abdominal approach. The primary objective of the study is to evaluate the major postoperative 30-day morbidity. Secondary objectives are to assess the overall 30-day morbidity, 30-day mortality, 30-day pulmonary morbidity, disease-free survival, overall survival as well as quality of life and to perform medico-economic analysis. A total of 200 patients will be enrolled, and two safety analyses will be performed using 25 and 50 patients included in arm A. DISCUSSION: Postoperative morbidity remains high after oesophageal cancer surgery, especially due to major pulmonary complications, which are responsible for 50% of the postoperative deaths. This study represents the first randomised controlled phase III trial to evaluate the benefits of the minimally invasive approach with respect to the postoperative course and oncological outcomes in oesophageal cancer surgery. TRIAL REGISTRATION: NCT00937456 (ClinicalTrials.gov).

[Cancer of the esophagus and gastroesophageal junction: evolution of surgical management]. / Cancer de l'oesophage et de la jonction oeso-gastrique: evolution de la stratégie chirurgicale.

Management of esophageal cancer has evolvedmarkedly in the last two decades. Advances in neoadjuvant treatment combined with refinements in surgical techniques and perioperative care have resulted in better postoperative outcomes and long-term survival. We investigated trends in the outcome of esophagectomy for esophageal cancer over the past 20 years at our high-volume institution. We studied patients who underwent surgery for primary cancer of the esophagus or gastroesophageal junction from 1988 through 2008 (N = 1153). Four study periods (P) were compared: 1988-1993 (P1), 1994-1998 (P2), 1999-2003 (P3) and 2004-2008 (P4). Demographic parameters, tumor characteristics, post-operative morbidity, in-hospital mortality and long-term survival were recorded prospectively and the four periods were compared retrospectively. Squamous cell carcinoma accountedfor 77.4% of the 1153 malignancies. The ratio of squamous cell carcinoma to adenocarcinoma fell from 12.0 to 1.3 during the study period (P1 vs P4, P < 0.001), with aparallel increase in the number tumors of the lower esophagus or gastroesophageal junction. The post-operative mortality and morbidity rates were respectively 5.6% and 42.7% overall and remained stable during the study period. The five-year survival rate among all resected patients improved significantly, from 24.3% to 42.7% (P1 vs P4, P< 0.001). The complete (RO) resection rate was 80.7% overall and increased from 74.1% to 82.1% (P1 vs P4, P < 0.05). The five-year survival rate improved significantly among RO-resected patients, from 32.7 % to 52.3 % (PI vs P4, P<.0001). The proportion of patients who received neoadjuvant treatment (mainly chemoradiotherapy) rose from 46.8% to 66.5%. The completeness of the pathologic response after neoadjuvant chemoradiotherapy correlated with long-term survival (P < 0.001): five-year survival rates among pathologically complete, partial and non responders were 52.1%, 24.8% and 10%, respectively. Short-term outcomes after resection remained stable during the study period and comparedfavorably with those reported by other high-volume institutions. Long-term survival improved significantly. Advances in staging methods andsurgical management, combined with more stringent patient selection and use of neoadjuvant chemoradiation, may explain this progress. More reliable predictors of complete RO resection and of the response to chemoradiation therapy are needed in order to tailor management to the individual patient.

Experience of gemcitabine plus oxaliplatin chemotherapy in patients with advanced biliary tract carcinoma.

BACKGROUNDS: The combination gemcitabine-oxaliplatin (GEMOX) is frequently used in patients with advanced biliary tract carcinoma (BTC). However, this is only based on phase II studies performed in selected patients.We assessed the efficacy and safety of the GEMOX regimen in non-selected patients with advanced BTC. METHODS: All consecutive patients with advanced BTC received the GEMOX regimen in a setting outside a study: gemcitabine 1,000 mg/m(2) on day 1, and oxaliplatin 100 mg/m(2) on day 2, treatment repeated every 2 weeks until progression or unacceptable toxicity. RESULTS: Forty-four patients were enrolled. EFFICACY: 1 complete and 6 partial responses (objective response rate = 16.3%), 18 tumour stabilizations (41.9%, disease control rate = 58.1%), median progression-free survival was 5.0 months and median overall survival was 11.0 months. TOXICITY: grade 3 neuropathy in 4 patients, grade 3 asthenia in 5 patients. CONCLUSION: The GEMOX combination was well tolerated, with a modest activity in non-selected patients with advanced BTC. This regimen should be compared to the new standard gemcitabine-cisplatin combination.

[What's new in esophageal cancer treatment]. / Prise en charge thérapeutique du cancer de l'oesophage.

The prognosis for esophageal cancer remains grim despite recent progress in diagnosis and treatment. Surgery is the standard treatment for stages I and II (only). Neoadjuvant chemotherapy or combined radiation and chemotherapy may be considered for stages IIb and III. Palliative surgery is no longer considered useful. Neoadjuvant or adjuvant radiation treatment does not improve survival. Adjuvant chemotherapy does not improve survival, and the benefits of its neoadjuvant use remain controversial in view of the discordant results. There is strong evidence that a neoadjuvant combination of radiation and chemotherapy improves resection and survival rates compared with surgery alone, but definitive proof is not currently available. Combined radiation and chemotherapy may be considered for locally advanced tumors in responding patients, with curative salvage surgery if the tumor persists. For patients whose tumor is inoperable, a combination of radiation and chemotherapy is the standard treatment.

Low frequency of AXIN2 mutations and high frequency of MUTYH mutations in patients with multiple polyposis.

Familial adenomatous polyposis has been linked to germline mutations in the APC tumor suppressor gene. However, a number of patients with familial adenomatous polyposis (with either classical or attenuated phenotype) have no APC mutation. Recently, germline mutations in the Wnt pathway component gene AXIN2 have been associated with tooth agenesis-colorectal cancer syndrome. Moreover, biallelic mutations in the base excision repair gene MUTYH have been associated with polyposis and early-onset colorectal cancer. The aim of this study was to further assess the contribution of AXIN2 and MUTYH to hereditary colorectal cancer susceptibility. AXIN2 and MUTYH genes were screened for germline mutations by PCR and direct sequencing in 39 unrelated patients with multiple adenomas or colorectal cancer without evidence of APC mutation nor mismatch repair defect. Two novel AXIN2 variants were detected in one patient with multiple adenomas, but no clearly pathogenic mutation. In contrast, nine different MUTYH mutations were detected in eight patients, including four novel mutations. Biallelic MUTYH mutations were only found in patients with multiple adenomatous polyposis (7 out of 22 (32%)). Interestingly, five MUTYH mutation carriers had a family history consistent with dominant inheritance. Moreover, one patient with biallelic MUTYH mutations presented with multiple adenomas and severe tooth agenesis. Therefore, germline mutations are rare in AXIN2 but frequent in MUTYH in patients with multiple adenomas. Our data suggest that genetic testing of MUTYH may be of interest in patients with pedigrees apparently compatible with autosomal recessive as well as dominant inheritance.

[Duodenal atresia and choledochal cyst: a rare combination]. / Atrésie duodénale et kyste du cholédoque: une association rare.

Congenital duodenal atresia is usually associated with various congenital anomalies. The embryological events in the development of the biliary tract and duodenum are linked. Although an association between duodenal atresia and biliary anomalies is predictable, it is rarely observed. We describe the case of a 27 year-old woman, operated on for duodenal atresia in her childhood, who presented cholangiolitis. Morphologic investigation allowed the diagnosis of choledochal cyst with an intracystic stone developed in the pancreatic head. A pancreatico-duodenectomy was performed because of the importance and the location of dilatation and stone with biliary obstruction. To our knowledge, the association between a congenital duodenal atresia and a choledochal cyst revealed at adult age had never been described in the literature.

[Ureteric and bladder involvement of deep pelvic endometriosis. Value of multidisciplinary surgical management]. / Atteinte urétérale et vésicale de l'endométriose pelvienne profonde. Interet de la prise en charge chirurgicale multidisciplinaire.

OBJECTIVES: To evaluate the clinical features, staging by medical imaging, treatment strategy and results of surgical management of deep pelvic endometriosis with bladder and/or ureteric involvement. MATERIALS AND METHODS: Eighteen cases of ureteric and/or bladder deep pelvic endometriosis (DPE) were treated in our centre between 1996 and 2004. Preoperative data (clinical symptoms, MR imaging), intraoperative data (resection and urinary tract diversion procedures, associated procedures on the genital and gastrointestinal tracts), and postoperative data (histological results, complications, anatomical follow-up by imaging and functional assessment) were reviewed. RESULTS: Urinary symptoms were present in 55% of cases, genital symptoms were present in 83% of cases and gastrointestinal symptoms were present in 46% of cases. A combination of gynaecological and gastrointestinal lesions was demonstrated on imaging in 82% of cases. The mean postoperative follow-up was 16 months (range: 6-36 months). Six patients presented anterior vesical endometriosis. In these cases, the sensitivity and specificity of MRI were 100%. Six partial cystectomies were performed. All corresponded to endometriotic lesions on histological examination. No cases of recurrence of vesical endometriosis were observed. Posterior endometriosis with ureteric involvement was observed in 13 patients (including one with vesical endometriosis). The ureteric lesion was asymptomatic in 8 out of 13 cases (61%). The diagnostic sensitivity of MRI was 92% for posterior nodules, identifying 4 lateral parametrial nodules and 8 median retrocervical nodules. Ureterohydronephrosis was observed in 3 patients with lateral parametrial nodules and 8 patients with median retrocervical nodules, and was bilateral for 3 patients, i.e. 14 dilated renal units. Surgical management consisted of 2 ureteric resections with end-to-end anastomosis, 3 psoas bladder reimplantations, and 9 ureterolyses (8 patients). Two out of 13 patients (15%) with ureteric lesions treated by ureterolysis developed recurrence of the ureteric stricture with upper tract dilatation related to recurrence of the lateral nodule. In 14 patients, genital and/or gastrointestinal resections were associated with the urinary tract procedure. CONCLUSION: Preoperative evaluation of all DPE lesions is based on MRI with reconstruction images of the ureter in the presence of urinary tract lesions. Systematic ureteric stenting prior to surgical dissection of the pelvic wall is recommended in patients with posterior nodules and in the case of partial cystectomy for anterior nodules when the ureteric meati are adjacent to the lesion. Ureteric reimplantation onto a psoas hitch bladder must be performed when the DPE lesions are extensive and partly resected or invade the ureteric wall. The frequency of associated lesions (urinary, gynaecological gastrointestinal) justifies a multidisciplinary surgical approach.

Mortality and morbidity after resection for adenocarcinoma of the gastroesophageal junction: predictive factors.

BACKGROUND: Resection for adenocarcinoma of the gastroesophageal junction (AGEJ) is associated with severe mortality and morbidity. This retrospective study aimed to evaluate mortality and morbidity after resection for AGEJ and to determine their predictive factors. STUDY DESIGN: Data from 1,192 patients (mean age 65 +/- 11 years) who underwent resection for AGEJ by members of French Association of Surgery from 1985 to 2000 were collected. A stepwise logistic regression model was built to identify by multivariate analysis the variables independently associated with mortality, morbidity, anastomotic leakage, and major pulmonary complications. RESULTS: Distribution of Siewert's type was: I = 480 (40%), II = 500 (42%), and III = 212 (18%). Most type I and II tumors were treated by esophagectomy and proximal gastrectomy (93% and 58%, respectively), using an approach including a thoracotomy (82% and 64%, respectively); type III tumors were treated mainly by total gastrectomy and distal esophagectomy (83%), through an exclusive transabdominal approach (69%). Seventy-six (6%) patients died postoperatively. Only American Society of Anesthesiologists (ASA) scores III and IV (p < 0.001) and period of study (p = 0.025) were predictive of mortality. Predictive factors of overall morbidity (overall rate = 35%) were high ASA score (p < 0.001), age more than 60 years (p = 0.020), male gender (p = 0.039), and cervical anastomosis (p = 0.001). Factors predictive of anastomotic leakage (overall rate = 9%) were high ASA score (p = 0.006) and manual anastomosis (p = 0.010). Factors predictive of major pulmonary complications (overall rate = 23%) were high ASA score (p = 0.015), age more than 60 years (p < 0.001), anastomotic leakage (p < 0.001), and abdominal complications (p = 0.003). CONCLUSIONS: ASA score is a reliable predictive factor of operative mortality and morbidity after resection of AGEJ.

Transcriptional regulation of human mucin MUC4 by bile acids in oesophageal cancer cells is promoter-dependent and involves activation of the phosphatidylinositol 3-kinase signalling pathway.

Abnormal gastro-oesophageal reflux and bile acids have been linked to the presence of Barrett's oesophageal premalignant lesion associated with an increase in mucin-producing goblet cells and MUC4 mucin gene overexpression. However, the molecular mechanisms underlying the regulation of MUC4 by bile acids are unknown. Since total bile is a complex mixture, we undertook to identify which bile acids are responsible for MUC4 up-regulation by using a wide panel of bile acids and their conjugates. MUC4 apomucin expression was studied by immunohistochemistry both in patient biopsies and OE33 oesophageal cancer cell line. MUC4 mRNA levels and promoter regulation were studied by reverse transcriptase-PCR and transient transfection assays respectively. We show that among the bile acids tested, taurocholic, taurodeoxycholic, taurochenodeoxycholic and glycocholic acids and sodium glycocholate are strong activators of MUC4 expression and that this regulation occurs at the transcriptional level. By using specific pharmacological inhibitors of mitogen-activated protein kinase, phosphatidylinositol 3-kinase, protein kinase A and protein kinase C, we demonstrate that bile acid-mediated up-regulation of MUC4 is promoter-specific and mainly involves activation of phosphatidylinositol 3-kinase. This new mechanism of regulation of MUC4 mucin gene points out an important role for bile acids as key molecules in targeting MUC4 overexpression in early stages of oesophageal carcinogenesis.

Factors predictive of complete resection of operable esophageal cancer: a prospective study.

BACKGROUND: Esophagectomy remains a standard treatment for patients with resectable esophageal cancer, but the 5-year survival is only 20% to 25%. After complete resection survival is significantly longer than after incomplete resection with microscopic or macroscopic penetration. The purpose of this study was to prospectively identify the factors predictive of complete resection of operable esophageal cancers. METHODS: Betwen January 1995 and January 2002, 372 patients with esophageal cancer underwent surgery with curative intent. Complete resection was performed in 304 patients (81.7%), incomplete resection with microscopic penetration in 28 (7.5%), and incomplete resection with macroscopic penetration in 40 (10.8%). Univariate and multivariate analysis included 16 preoperative and operative factors. RESULTS: Factors predictive of complete resection were absence of any modification of the esophageal axis on the barium swallow (p = 0.019) and a partial or complete response to preoperative radiochemotherapy (p = 0.042). Three groups of patients were identified: group 1 had no deviation of the axis on the barium swallow (n = 253); group 2 had deviation of the axis on the barium swallow and partial or complete response to radiochemotherapy (n = 66); and group 3 had deviation of the axis on the barium swallow and no response to radiochemotherapy or no preoperative treatment (n = 53). Rates of complete resection were 90.1%, 74.2%, and 50.9%, and 5-year actuarial survivals were 46%, 37%, and 0%, respectively (p < 0.001). CONCLUSIONS: Complete resection of esophageal cancer is predictable. Deviation axis on the barium swallow and morphologic response to neoadjuvant radiochemotherapy are variables available for all patients at onset of therapeutic management.

[Factors predictive of complete resection of operable esophageal cancer: review of 746 patients]. / Facteurs prédictifs de résection complète des cancers de l'oesophage opérables.

OBJECTIVE: Surgery is the treatment of reference for early-stage esophageal cancer, but 5-year survival is only 20% to 25%. After complete resection (R0), survival is significantly longer than after incomplete resection, with microscopic (R1) or macroscopic (R2) penetration. The purpose of this work was to identify retrospectively the factors predictive of complete resection of operable esophageal cancers. PATIENTS AND METHODS: Between January 1982 and March 2001, 746 patients with esophageal cancer underwent curative surgery. R0 resection was performed in 585 patients (78.4%), R1 in 61 (8.2%) and R2 in 100 (13.4%). Univariate and multivariate analysis included 28 preoperative, clinical, tumor and therapeutic parameters. RESULTS: Multivariate analysis showed that factors predictive of complete resection R0 were: absence of any modification of the esophageal axis on the barium swallow (P=0.054), a partial or complete response to preoperative radio-chemotherapy (P=0.042), tumor height<10 cm (P=0.1) and tumor diameter<30 mm (P=0.01). Three groups of patients were identified from the 2 most significant variables. Group 1: no deviation of the axis on the barium swallow (n=501). Group 2: deviation of the axis on the barium swallow and partial or complete response to radiochemotherapy (n=91). Group 3: deviation of the axis on the barium swallow and no response to radiochemotherapy or no preoperative treatment (n=126). For the three groups, rate of R0 resection was 82.6%, 80.1% and 61.1% and 5-year actuarial survival 36%, 27% and 14%, respectively. These rates were significantly different between groups (P<10(- 4)) and two by two (P<0.04). CONCLUSION: Complete resection of esophageal cancer is predictable. After validation with an independent population the findings presented here could be used to establish stratification criteria for future therapeutic trials.

[Fundic endocrine tumors and atrophic gastritis: the value of antrectomy]. / Tumeurs endocrines fundiques sur gastrite atrophique: intérêt de l'antrectomie.

We report two cases of fundic endocrine tumors associated with fundic atrophic gastritis-related hypergastrinemia and treated by antrectomy. About twenty infracentimetric tumors were observed in each patient and restrictively involved fundic mucosa. Antrectomy induced normalization of gastrinemia and the disappearance of fundic tumors, as soon as the 4(th) and 7(th) month. No recurrence was observed during the 5-year and 18-month follow-up time, respectively. We therefore consider that antrectomy may be regarded as a useful alternative treatment in the management of atrophic gastritis-related fundic endocrine tumors.

[Ambulatory emergency surgery]. / Quelle place pour les urgences en chirurgie ambulatoire ?

Development of outpatient cases in emergency is still a controversy. Ambulatory surgery is possible in ambulatory surgical unit (ASU), or in emergency surgical units (ESU). Quality of care and safety need to be associated to patients' ambulatory management without impairment of ASU and ESU organization. Patient eligibility concerns not only traumatic hand surgery but also general or visceral surgery.

Surgery alone versus chemoradiotherapy followed by surgery for stage I and II esophageal cancer: final analysis of randomized controlled phase III trial FFCD 9901.

PURPOSE: Although often investigated in locally advanced esophageal cancer (EC), the impact of neoadjuvant chemoradiotherapy (NCRT) in early stages is unknown. The aim of this multicenter randomized phase III trial was to assess whether NCRT improves outcomes for patients with stage I or II EC. METHODS: The primary end point was overall survival. Secondary end points were disease-free survival, postoperative morbidity, in-hospital mortality, R0 resection rate, and prognostic factor identification. From June 2000 to June 2009, 195 patients in 30 centers were randomly assigned to surgery alone (group S; n = 97) or NCRT followed by surgery (group CRT; n = 98). CRT protocol was 45 Gy in 25 fractions over 5 weeks with two courses of concomitant chemotherapy composed of fluorouracil 800 mg/m(2) and cisplatin 75 mg/m(2). We report the long-term results of the final analysis, after a median follow-up of 93.6 months. RESULTS: Pretreatment disease was stage I in 19.0%, IIA in 53.3%, and IIB in 27.7% of patients. For group CRT compared with group S, R0 resection rate was 93.8% versus 92.1% (P = .749), with 3-year overall survival rate of 47.5% versus 53.0% (hazard ratio [HR], 0.99; 95% CI, 0.69 to 1.40; P = .94) and postoperative mortality rate of 11.1% versus 3.4% (P = .049), respectively. Because interim analysis of the primary end point revealed an improbability of demonstrating the superiority of either treatment arm (HR, 1.09; 95% CI, 0.75 to 1.59; P = .66), the trial was stopped for anticipated futility. CONCLUSION: Compared with surgery alone, NCRT with cisplatin plus fluorouracil does not improve R0 resection rate or survival but enhances postoperative mortality in patients with stage I or II EC.
