DDS-SIRC Cooperative Conferences Feel the Burn: RFA for Chronic Radiation Proctitis.

Chronic radiation proctitis, although relatively rare, can be the source of severe comorbidity in patients who had undergone prior radiotherapy for pelvic malignancy. Although current treatments for radiation proctitis include argon plasma coagulation, heater probe, bipolar neodymium/yttrium aluminum garnet (Nd: YAG) lasers, these interventions are often burdened by the frequent occurrence of rectal ulcerations and stenosis. Since radiofrequency ablation (RFA) is frequently used to ablate esophageal malignancy and pre-malignancy, we report the efficacy of RFA using through the scope system in two patients with rectal bleeding due to radiation proctitis. In both cases, the procedure was well-tolerated with hemostasis achieved after 1 or 2 sessions of RFA. Mucosal re-epithelialization was observed in areas of previous bleeding with no stenosis or ulceration observed at follow-up.

Pancreatic Neuroendocrine Tumors in Patients with Multiple Endocrine Neoplasia Type 1: Diagnostic Value of Different MRI Sequences.

BACKGROUND: MRI is a useful imaging modality to assess the presence of pancreatic neuroendocrine tumors (PNETs), allowing repeat monitoring examinations in multiple endocrine neoplasia type 1 (MEN-1) patients. OBJECTIVES: We aimed to compare the diagnostic accuracy of conventional MRI sequences to identify which sequence better depicts the presence of PNETs in MEN-1 patients. METHOD: We performed a retrospective analysis of consecutive MEN-1 patients who underwent a conventional MRI protocol to monitor previously proven PNETs. MRI sequences T1-w chemical shift (CS), T2-w HASTE, fat-suppressed (FS) T2-w HASTE, diffusion-weighted imaging (DWI), and pre- and post-contrast FS T1-w sequences were independently analyzed by 2 experienced radiologists using a 3-grade score (no lesion, uncertain lesion, and certain lesion); lesion size and signal intensity were recorded. A Friedman ANOVA and a Wilcoxon pairwise test for the post hoc analysis were used. The sensitivity of each sequence was measured, and the results were analyzed with the χ2 test. RESULTS: We included 21 patients with a total of 45 PNETs proven by histology, endoscopic ultrasonography-guided fine-needle aspiration, CT, and nuclear medicine studies. A statistically significant (p < 0.01) difference was observed in the detection performance of each MRI sequence, particularly between DWI (91%) and T2-w FS (85%) sequences in comparison to the others (T1-w CS, T2-w, and pre- and post-contrast FS T1-w, ≤56% for all); no significant (p = 0.5) difference was found between the detection performance of DWI and T2-w FS sequences. No correlation was observed between the qualitative score of each sequence and lesion tumor size. CONCLUSIONS: DWI and T2-w FS sequences proved to be the most accurate in the detection of PNETs, thus suggesting a role for an abbreviated MRI protocol without contrast medium administration for monitoring MEN-1 patients.

Naples Prognostic Score, Based on Nutritional and Inflammatory Status, is an Independent Predictor of Long-term Outcome in Patients Undergoing Surgery for Colorectal Cancer.

BACKGROUND: The existing scores reflecting the patient's nutritional and inflammatory status do not include all biomarkers and have been poorly studied in colorectal cancers. OBJECTIVE: The purpose of this study was to assess a new prognostic tool, the Naples prognostic score, comparing it with the prognostic nutritional index, controlling nutritional status score, and systemic inflammation score. DESIGN: This was an analysis of patients undergoing surgery for colorectal cancer. SETTINGS: The study was conducted at a university hospital. PATIENTS: A total of 562 patients who underwent surgery for colorectal cancer in July 2004 through June 2014 and 468 patients undergoing potentially curative surgery were included. MaxStat analysis dichotomized neutrophil:lymphocyte ratio, lymphocyte:monocyte ratio, prognostic nutritional index, and the controlling nutritional status score. The Naples prognostic scores were divided into 3 groups (group 0, 1, and 2). The receiver operating characteristic curve for censored survival data compared the prognostic performance of the scoring systems. MAIN OUTCOME MEASURES: Overall survival and complication rates in all patients, as well as recurrence and disease-free survival rates in radically resected patients, were measured. RESULTS: The Naples prognostic score correlated positively with the other scoring systems (p < 0.001) and worsened with advanced tumor stages (p < 0.001). Patients with the worst Naples prognostic score experienced more postoperative complications (all patients, p = 0.010; radically resected patients, p = 0.026). Compared with group 0, patients in groups 1 and 2 had worse overall (group 1, HR = 2.90; group 2, HR = 8.01; p < 0.001) and disease-free survival rates (group 1, HR = 2.57; group 2, HR = 6.95; p < 0.001). Only the Naples prognostic score was an independent significant predictor of overall (HR = 2.0; p = 0.03) and disease-free survival rates (HR = 2.6; p = 0.01). The receiver operating characteristic curve analysis showed that the Naples prognostic score had the best prognostic performance and discriminatory power for overall (p = 0.02) and disease-free survival (p = 0.04). LIMITATIONS: This is a single-center study, and its validity needs additional external validation. CONCLUSIONS: The Naples prognostic score is a simple tool strongly associated with long-term outcome in patients undergoing surgery for colorectal cancer.

Is complete mesocolic excision with central vascular ligation safe and effective in the surgical treatment of right-sided colon cancers? A prospective study.

PURPOSE: Complete mesocolic excision (CME) with central vascular ligation (CVL) has been proposed for treatment of colon cancers based on the same principles as total mesorectal excision. Impressive outcomes have been reported, however, direct comparisons with the classic procedure are lacking. METHODS: Forty-five consecutive patients operated on in the last 5 years with CME and CVL right hemicolectomy entered the study. Fifty-eight right-sided colon cancer patients operated in the previous 5 years with classic approach constituted the control group. Intra- and postoperative course assessed the safety of the procedure. Primary end-points for oncological adequacy were recurrence and survival rate. RESULTS: All operations were successful with no increase in postoperative complications (p = 0.85). Number of harvested nodes and length of vascular ligation were shown to be significantly better in the CME group (p < 0.01). A higher number of tumor deposits were harvested thus allowing chemotherapy in newly upstaged patients. Locoregional recurrences were never experienced in CME patients (p = 0.03). The risk of cancer-related death was reduced by over one half in all CME patients, and even by three quarters in node-positive tumors. The classic operation was significantly associated with poor outcome (p < 0.01). CONCLUSION: This study shows that CME with CVL is a safe and effective surgical approach for right colon cancer, thus confirming the previously reported oncological adequacy. The procedure was shown to significantly decrease local recurrences and to improve the survival rate, particularly in node-positive patients. Urgent diffusion of this technique is warranted.

Foregut duplication of the stomach diagnosed by endoscopic ultrasound guided fine-needle aspiration cytology: case report and literature review.

Gastric duplication cyst (GDC) with a pseudostratified columnar ciliated epithelium is an uncommon malformation supposed to originate from a respiratory diverticulum arising from the ventral foregut. Morphologic appearance of GDCs is variable, depending on the density of their contents. GDCs are often misdiagnosed as solid masses by imaging techniques, and as a consequence they may be wrongly overtreated. We report our case of a 56-year-old man with a 5 cm hypoechoic mass of the gastroesophageal junction, incidentally detected by transabdominal ultrasonography. Neither transabdominal ultrasonography nor magnetic resonance clearly outlined the features of the lesion. The patient underwent endoscopic ultrasound (EUS), which showed a hypoechoic mass arising from the fourth layer of the anterior gastric wall, just below the gastroesophageal junction. According to EUS features, a diagnosis of gastrointestinal stromal tumor was suggested. EUS-guided fine-needle aspiration cytology revealed a diagnosis of GDC with pseudostratified columnar ciliated epithelium. We therefore performed an endoscopically-assisted laparoscopic excision of the cyst.In conclusion, whenever a subepithelial gastric mass is found in the upper part of the gastric wall, a duplication cyst, although rare, should be considered. In this case, EUS-guided fine-needle aspiration cytology could provide a cytological diagnosis useful to arrange in advance the more adequate surgical treatment.

Is the advanced age a contraindication to GERD laparoscopic surgery? Results of a long term follow-up.

BACKGROUND: In this prospective non randomized observational cohort study we have evaluated the influence of age on outcome of laparoscopic total fundoplication for GERD. METHODS: Six hundred and twenty consecutive patients underwent total laparoscopic fundoplication for GERD. Five hundred and twenty-four patients were younger than 65 years (YG), and 96 patients were 65 years or older (EG). The following parameters were considered in the preoperative and postoperative evaluation: presence, duration, and severity of GERD symptoms, presence of a hiatal hernia, manometric and 24 hour pH-monitoring data, duration of operation, incidence of complications and length of hospital stay. RESULTS: Elderly patients more often had atypical symptoms of GERD and at manometric evaluation had a higher rate of impaired esophageal peristalsis in comparison with younger patients. The duration of the operation was similar between the two groups. The incidence of intraoperative and postoperative complications was low and the difference was not statistically significant between the two groups. An excellent outcome was observed in 93.0% of young patients and in 88.9% of elderly patients (p = NS). CONCLUSIONS: Laparoscopic antireflux surgery is a safe and effective treatment for GERD even in elderly patients, warranting low morbidity and mortality rates and a significant improvement of symptoms comparable to younger patients.

Mallory-Weiss syndrome from giant gastric trichobezoar: A case report.

BACKGROUND: Mallory-Weiss syndrome (MWS), representing a linear mucosal laceration at the gastroesophageal junction, is a quite frequent cause of upper gastrointestinal bleeding, usually induced by habitual vomiting. The subsequent cardiac ulceration in this condition is likely due to the concomitance of increased intragastric pressure and inappropriate closure of the gastroesophageal sphincter, collectively inducing ischemic mucosal damage. Usually, MWS is associated with all vomiting conditions, but it has also been described as a complication of prolonged endoscopic procedures or ingested foreign bodies. CASE SUMMARY: We described herein a case of upper gastrointestinal bleeding in a 16-year-old girl with MWS and chronic psychiatric distress, the latter of which deteriorated following her parents' divorce. The patient, who was residing on a small island during the coronavirus disease 2019 pandemic lockdown period, presented with a 2-mo history of habitual vomiting, hematemesis, and a slight depressive mood. Ultimately, a huge intragastric obstructive trichobezoar was detected and discovered to be due to a hidden habit of continuously eating her own hair; this habit had persisted for the past 5 years until a drastic reduction in food intake and corresponding weight loss occurred. The relative isolation in her living status without school attendance had worsened her compulsory habit. The hair agglomeration had reached such enormous dimensions and its firmness was so hard that its potential for endoscopic treatment was judged to be impossible. The patient underwent surgical intervention instead, which culminated in complete removal of the mass. CONCLUSION: According to our knowledge, this is the first-ever described case of MWS due to an excessively large trichobezoar.

Case of fake acute abdomen by metastatic melanoma.

Malignant melanoma is the neoplasm with highest probability of cardiac metastatization. Cardiac involvement by metastatic melanoma is rarely identified ante-mortem (5-30% of cases) for non-specificity of cardiac symptoms. In fact we show in this case report that abdominal pain can represent the predominant symptom. Furthermore we show the importance of linkage between clinical & anamnestic data which if underestimated can lead to an improper management and to the patient exitus.

CXCR4-CXCL12-CXCR7 and PD-1/PD-L1 in Pancreatic Cancer: CXCL12 Predicts Survival of Radically Resected Patients.

Pancreatic ductal adenocarcinoma (PDAC) is currently the most deadly cancer. Although characterized by 5-20% of neoplastic cells in the highly fibrotic stroma, immunotherapy is not a valid option in PDAC treatment. As CXCR4-CXCL12 regulates tumor invasion and T-cell access and PD-1/PD-L1 controls immune tolerance, 76 PDACs were evaluated for CXCR4-CXCL12-CXCR7 and PD-1/PD-L1 in the epithelial and stromal component. Neoplastic CXCR4 and CXCL12 discriminated PDACs for recurrence-free survival (RFS), while CXCL12 and CXCR7 discriminated patients for cancer-specific survival (CSS). Interestingly, among patients with radical resection (R0), high tumor CXCR4 clustered patients with worse RFS, high CXCL12 identified poor prognostic patients for both RFS and CSS, while stromal lymphocytic-monocytic PD-L1 associated with improved RFS and CSS. PD-1 was only sporadically expressed (<1%) in focal lymphocyte infiltrate and does not impact prognosis. In multivariate analysis, tumoral CXCL12, perineural invasion, and AJCC lymph node status were independent prognostic factors for RFS; tumoral CXCL12, AJCC Stage, and vascular invasion were independent prognostic factors for CSS. CXCL12's poor prognostic meaning was confirmed in an additional perspective-independent 13 fine-needle aspiration cytology advanced stage-PDACs. Thus, CXCR4-CXCL12 evaluation in PDAC identifies prognostic categories and could orient therapeutic approaches.

Endoscopic resection of tracheal lobular capillary haemangioma with ultrasonically activated device.

We reported the case of a 55-year-old man with a large tracheal lobular capillary haemangioma attached to posterior tracheal wall and successfully managed with arterial embolization followed by endoscopic resection using Harmonic™ ACE Plus. Because of the high risk of bleeding, Harmonic™ was used in this case due to its ability to cut and cauterize simultaneously. The instrument jaw repeatedly grasped the attachment point of tumor, and then the cavitation effect, created by the longitudinal vibration of the blade tip, separated it from the posterior tracheal wall, reducing the risk of perforation. Yet, the ultrasonic energy denatured proteins and coagulated the vessels, preventing the bleeding during resection. No complications occurred during and after the procedure. Twelve-month follow-up showed no recurrence.

Weekly chemotherapy with cisplatin and paclitaxel and concurrent radiation therapy as preoperative treatment in locally advanced esophageal cancer: a phase II study.

We evaluated the association of a weekly cisplatin (35 mg/mq) and paclitaxel (45 mg/mq) regimen with radiotherapy (46 Gy) as primary treatment in locally advanced esophageal cancer (LAEC). The main end point was the activity in terms of pathologic complete response (pathCR) rate. Thirty-three LAEC patients received chemoradiation therapy during weeks 1-6 followed by esophagectomy. A pathCR was observed in 10/33 patients; 20/33 and 3/33 patients showed PR and SD, respectively. The EUS maximal transverse cross sectional area reduction >50% significantly correlated with pathCR. Three-year survival rate was 35%. These results support the activity and mild toxicity of this regimen.

Synchronous colorectal neoplasias: our experience about laparoscopic-TEM combined treatment.

Synchronous colorectal neoplasias are defined as 2 or more primary tumors identified in the same patient and at the same time. The most voluminous synchronous cancer is called "first primitive" or "index" cancer. The aim of this work is to describe our experience of minimally invasive approach in patients with synchronous colorectal neoplasias.Since January 2001 till December 2009, 557 patients underwent colectomy for colorectal cancer at the Department of General and Emergency Surgery of the University of Perugia; 128 were right colon cancers, 195 were left colon cancers while 234 patients were affected by rectal cancers. We performed 224 laparoscopic colectomies (112 right, 67 left colectomies and 45 anterior resections of rectum), 91 Transanal Endoscopic Microsurgical Excisions (TEM) and 53 Trans Anal Excisions (TAE). In the same observation period 6 patients, 4 males and 2 females, were diagnosed with synchronous colorectal neoplasias. Minimal invasive treatment of colorectal cancer offers the opportunity to treat two different neoplastic lesions at the same time, with a shorter post-operative hospitalization and minor complications. According to our experience, laparoscopy and TEM may ease the treatment of synchronous diseases with a lower morbidity rate.

Lanreotide Therapy vs Active Surveillance in MEN1-Related Pancreatic Neuroendocrine Tumors < 2 Centimeters.

PURPOSE: Pancreatic neuroendocrine tumors (pNETs) are frequent in multiple endocrine neoplasia type 1 (MEN1) syndrome. They are usually not surgically treated unless larger than 1 to 2 cm or a growth rate > 0.5 cm per year. Somatostatin analogues represent one of the main therapeutic options in pNETs, but they have never been prospectively investigated in MEN1-related pNETs. The aim of this study was to prospectively evaluate the effectiveness of lanreotide in patients with MEN1-related pNETs < 2 cm. METHODS: MEN1 patients with 1 or more pNETs < 2 cm of maximal diameter were considered. Study design was prospective observational, comparing patients treated with lanreotide autogel 120 mg every 28 days (LAN group) and patients in active surveillance, not receiving any therapy (AS group). RESULTS: Forty-two patients were enrolled: 23 in LAN and 19 in AS group. Median follow-up was 73 months. Initial imaging identified a total of 91 pNETs. The median progression-free survival was significantly longer in the LAN than in the AS group (median not reached vs 40 months, P < 0.001). In the LAN group, 4 patients had an objective tumor response, 15 patients had stable disease, while 4 had tumor progression. In the AS group, 13 patients had pNET progression, while 6 were stable. CONCLUSIONS: This is the first prospective study evaluating the efficacy of somatostatin analogues in MEN1-related pNETs. These findings highlight that lanreotide autogel is effective as antiproliferative therapy in MEN1-related pNETs < 2cm, suggesting the utility of somatostatin analogues to arrest the development of tumor lesions as well as to delay or avoid pancreatic surgery.

Lymph Node Ratio Versus TNM System As Prognostic Factor in Colorectal Cancer Staging. a Single Center Experience.

OBJECTIVE: This study aims to establish the actual validity of the lymph node ratio (LNR) as a prognostic factor for colorectal cancer patients, and to verify differences of survival and disease-free interval. METHODS: Patients referred with colorectal cancer who underwent potentially curative surgery between January 1997 and December 2011 were included. Lymph node ratio, TNM staging and survival were extracted from surgical, histological and follow-up records. RESULTS: Two hundred eigthy six patients with different stages of colorectal cancer underwent surgery, with comparison of survival prediction based on lymph node ratio and TNM staging. The overall survival rate was 78.3%, the recurrence rate was 11.9% and the mortality rate was estimated as 21.7%. Univariate analysis in relation to survival was significant for the following variables: serum level of CEA, CA 19.9 value, degree of histological differentiation, and tumor growth. There weren't any statistically significant differences for the LNR (LNR

Diagnosis and therapeutic management of cystic dystrophy of the duodenal wall in heterotopic pancreas. A case report and revision of the literature.

CONTEXT: Cystic dystrophy in heterotopic pancreas is a rare and serious condition. Diagnosis is difficult because of non-specific clinical manifestations and radiologic and endoscopic imaging are pivotal. Therapeutic management is still under debate. CASE REPORT: We describe a case of cystic dystrophy of the duodenal wall in heterotopic pancreas complicated with chronic pancreatitis and pancreatic cystadenoma. DISCUSSION: Computed tomography and magnetic resonance are very useful in demonstrating the presence of cysts in a thickened duodenal wall but, for the most part, endoscopic ultrasonography is the most useful imaging examination. The choice of different therapeutic options is still under debate; although some authors have proposed a medical approach using octreotide or endoscopic treatment for selected patients, a pancreaticoduodenectomy is usually proposed for symptomatic patients. CONCLUSION: When surgery is needed, a pancreaticoduodenectomy is preferred, reserving by-pass procedures for high risk patients. Because of the non-specific clinical manifestation and the very difficult diagnosis and therapeutic management, these patients should be studied and treated in specialized and dedicated centers.

Pancreaticoduodenectomy as the primary therapeutic choice in cystic dystrophy of the duodenal wall in heterotopic pancreas.

On the basis of a review of the literature and description of a clinical case, the aim of this paper was to evaluate the role of pancreaticoduodenectomy as the primary therapeutic choice in a rare, serious condition such as cystic dystrophy of the duodenal wall in heterotopic pancreas. The diagnosis is difficult because of the non-specific clinical manifestations, and radiological and endoscopic imaging are decisive. Computed tomography and magnetic resonance are very useful for demonstrating the presence of cysts in a thickened duodenal wall but endoscopic ultrasonography is the most useful imaging examination. The choice of therapeutic option is still debated. Although some Authors have proposed a medical approach using octreotide or endoscopic treatment for selected patients, pancreaticoduodenectomy is usually proposed for symptomatic patients. When surgery is needed, pancreaticoduodenectomy should be preferred, reserving by-pass procedures for high-risk patients. Because of the non-specific clinical manifestations and the very difficult diagnostic and therapeutic management, these patients need to be studied and treated in specialised, dedicated centres.

[Laparoscopic total fundoplication is not an obstacle to oesophageal emptying after oesophago-gastric myotomy for the surgical treatment of achalasia]. / La fundoplicatio totale non ostacola lo svuotamento esofageo dopo miotomia esofago-gastrica estesa per il trattamento chirurgico dell'acalasia esofagea.

There are different surgical possibilities for the treatment of oesophageal achalasia ranging from a short extramucosal oesophagomyotomy to an extended esophago-gastric myotomy combined with a partial fundoplication to restore the main antireflux barrier. A total 360 degrees fundoplication is generally regarded as an obstacle to oesophageal emptying. The aim of this study was to evaluate the role and efficacy of total 360 degrees laparoscopic Nissen-Rossetti fundoplication after oesophago gastric myotomy in the treatment of oesophageal achalasia. From 1992 to January 2008, a total of 245 patients (112 males, 133 females), mean age 45.1 years (range: 12-79), were submitted to laparoscopic Nissen-Rossetti fundoplication after a Heller myotomy with endoscopic and manometric intraoperative monitoring. In 3 patients (1.2%), conversion to laparotomy was necessary. Mean operative time was 60 +/- 15 minutes. No mortality was observed. The overall morbidity rate was 1.6%. The mean postoperative hospital stay was 3.5 +/- 1.0 days (range: 1-12 days). A mean clinical follow-up of 100.2 +/- 7 months (range: 3-177) was possible for 228 patients (93.1%), and an excellent or good outcome was observed in 209 patients (91.7%) (DeMeester dysphagia score 0-1). No improvement in dysphagia was observed in 5 (2.2%) patients. Pathological gastro-oesophageal reflux was absent in all patients. Laparoscopic Nissen-Rossetti fundoplication after a Heller myotomy is a safe, effective treatment for oesophageal achalasia with excellent results in terms of dysphagia resolution, affording total protection from the onset of gastrooesophageal reflux.

Laparoscopic conversion of an omega in a Roux-en-y reconstruction after mini-invasive total gastrectomy for cancer: a technical report.

INTRODUCTION: Few cases of laparoscopic total gastrectomy have been published. Reconstruction of the digestive tract was generally accomplished with a Roux-en-y esophagojejunal mechanical anastomosis. Here we report the first 2 cases of laparoscopic conversion of an omega in a Roux-en-y reconstruction due to the occurrence of a severe alkaline esophagitis after mini-invasive total gastrectomy for cancer. MATERIALS AND METHODS: Two male patients presented in 2004. One year prior, at another facility, they had undergone laparoscopic total gastrectomy for cancer, with reconstruction of digestive tract by means of an esophagojejeunostomy with a jejunal loop and Braun's side-to-side enteroanastomosis. They complained of daily symptoms of nausea, regurgitation, heartburn, and early postprandial fullness with reduction of appetite and weight loss of almost 15 kg. Instrumental examination diagnosed alkaline esophagitis. Intervention was performed via laparoscopic approach and the digestive reconstruction was reconfigured in a Roux-en-y type with a proximal limb of almost 60 cm. RESULTS: Operative time was 135 to 180 minutes. No postoperative complications occurred. After 1-year follow-up, symptoms resolution and esophagitis healing have been observed in both patients. CONCLUSIONS: Laparoscopic gastrectomy is gaining wide acceptance. In our opinion, a standardization of the technique is necessary: we believe Roux-en-y should be considered the preferred reconstruction route ensuring the best protection of the esophagus from alkaline reflux.

Preoperative Neutrophil to Lymphocyte Ratio and Lymphocyte to Monocyte Ratio are Prognostic Factors in Gastric Cancers Undergoing Surgery.

BACKGROUND: Cancer outcome is considered to result from the interplay of several factors, among which host inflammatory and immune status are deemed to play a significant role. The neutrophil-to-lymphocyte ratio (NLR) and the lymphocyte-to-monocyte ratio (LMR) have been profitably used as surrogate markers of host immunoinflammatory status and have also been shown to correlate with outcome in several human tumors. However, only a few studies on these biomarkers have been performed in gastric cancer patients, yielding conflicting results. METHODS: Data were retrieved from a prospective institutional database. Overall survival (OS) of 401 patients undergoing surgery for gastric cancer between January 2000 and June 2015 as well as disease-free survival (DFS) rates in 297 radically resected patients were calculated. MaxStat analysis was used to select cutoff values for NLR and LMR. RESULTS: NLR and LMR did not significantly correlate with tumor stage. Patients with a high NLR and a low LMR experienced more tumor recurrences (p < 0.001) and had a higher hazard ratio (HR) for both OS (HR = 2.4 and HR = 2.10; p < 0.001) and DFS (HR = 2.99 and HR = 2.46; p < 0.001) than low NLR and high LMR subjects. Both biomarkers were shown to independently predict OS (HR = 1.65, p = 0.016; HR = 2.01, p = 0.002, respectively) and DFS (HR = 3.04, p = 0.019; HR = 4.76, p = 0.002, respectively). A score system combining both biomarkers was found to significantly correlate with long-term results. CONCLUSIONS: A simple prognostic score including preoperative NLR and LMR can be used to easily predict outcome in gastric cancer patients undergoing surgery.

Gastroesophageal junction adenocarcinoma: what are the factors influencing long-term survival?

The incidence of gastroesophageal junction adenocarcinoma is increasing. About 30% of the tumors cannot be completely resected, and 40% of the patients relapse after complete resection. There is much controversy over the role of neoadjuvant therapy, the approach route, lymphadenectomy, and the extent of esophageal resection. The aim of our study was to report our experience in the treatment of gastroesophageal junction adenocarcinoma. From January 1987 until February 2005, 157 patients (125 men, 32 women), mean age 72.1 +/- 3.2 years, came for observation. One hundred sixteen patients underwent curative intervention. Mean operative time was 185 +/- 45 minutes. Mean postoperative hospital stay was 16.4 +/- 6.1 days. Postoperative complications were observed in 25 patients (21.6%); 6 patients (5.2%) died during the postoperative period. Overall survival was 36.2% and 27.6% at 3- and 5-year follow-up, respectively. Five-year survival rate was significantly lesser in R1/R2 versus R0 resections (0% versus 33.7%), N+ versus N- patients (11.3% versus 53.3%), and worsened with progression of pT histological staging (T1, 100%; T2, 24.1%; T3, 15.1%; T4, 0%). Determining prognostic factors are the radicality of resection, lymph nodal invasion, and histological staging.
