RESUMO
AF1q associates with tumor progression and metastases upon WNT signaling. The downstream WNT target CD44 has demonstrated prognostic significance in gastric cancer (GC). This study evaluates the impact of AF1q on tumor stage and survival in GC patients. Immunohistochemical marker expression was analyzed and data were processed to correlation and survival analysis. Out of 182 GC samples, 178 (97.8%) showed moderate to high AF1q expression (p < 0.001), these samples correlated with positive lymph node stage (p = 0.036). In a subgroup analysis of patients with nodal-positive GC (n = 129, 70.9%), enhanced tumoral AF1q expression resulted in impaired recurrence-free survival (RFS, p = 0.030). Enhanced tumoral CD44 expression resulted in impaired disease-specific survival (DSS) in the subgroup of patients with nodal-positive GC (p = 0.031) as well as in the overall GC group (p = 0.005). AF1q demonstrated as an independent prognostic marker for RFS (p = 0.035) and CD44 for DSS (p = 0.036). AF1q has shown potential for prognostication of RFS in GC patients and is predominantly expressed in nodal-positive GC. Testing AF1q provides a possibility of identifying patients with locoregional (and advanced) disease, particularly at risk for disease recurrence. Implementing AF1q into the diagnostic process may facilitate screening, prognosis estimation as well as consideration of preoperative multimodal treatment in patients qualifying for elective upfront surgery.

OBJECTIVE: To investigate the oncological outcomes of patients with pancreatic ductal adenocarcinoma (PDAC) who had an R 0 or R 1 resection based on the revised R status (1 mm) after neoadjuvant therapy (NAT). BACKGROUND: The revised R status is an independent prognostic factor in upfront-resected PDAC; however, the significance of 1 mm margin clearance after NAT remains controversial. METHODS: Patients undergoing pancreatectomy after NAT for PDAC were identified from 2 prospectively maintained databases. Clinicopathological and survival data were analyzed. The primary outcomes were overall survival (OS), recurrence-free survival (RFS), and pattern of recurrence in association with R 0 >1 mm and R 1 ≤1 mm resections. RESULTS: Three hundred fifty-seven patients with PDAC were included after NAT and subsequent pancreatic resection. Two hundred eight patients (58.3%) received FOLFIRINOX, 41 patients (11.5%) received gemcitabine-based regimens, and 299 individuals (83.8%) received additional radiotherapy. R 0 resections were achieved in 272 patients (76.2%) and 85 patients (23.8%) had R 1 resections. Median OS after R 0 was 41.0 months, compared with 20.6 months after R 1 resection ( P = 0.002), and even longer after additional adjuvant chemotherapy ( R 0 44.8 vs R1 20.1 months; P = 0.0032). Median RFS in the R 0 subgroup was 17.5 months versus 9.4 months in the R 1 subgroup ( P < 0.0001). R status was confirmed as an independent predictor for OS ( R 1 hazard ratio: 1.56, 95% CI: 1.07-2.26) and RFS ( R 1 hazard ratio: 1.52; 95% CI: 1.14-2.0). In addition, R 1 resections were significantly associated with local but not distant recurrence ( P < 0.0005). CONCLUSIONS: The revised R status is an independent predictor of postresection survival and local recurrence in PDAC after NAT. Achieving R 0 resection with a margin of at least 1 mm should be a primary goal in the surgical treatment of PDAC after NAT.

PURPOSE: Gastroesophageal adenocarcinoma is associated with poor prognosis, even in resectable stages. Systemic inflammation plays a key role in cancer progression. Yet, information on prognostic values of systemic inflammatory parameters in European cohorts is scarce. METHODS: We analysed systemic inflammatory biomarkers (neutrophil-to-lymphocyte ratio (NLR), leucocyte-to-lymphocyte ratio (LLR), platelet-to-lymphocyte ratio (PLR), systemic inflammation response index (SIRI) and modified Glasgow Prognostic Score (mGPS)) at the time of cancer diagnosis and their association with overall survival (OS) in patients with gastroesophageal adenocarcinoma treated at the Medical University of Vienna between 1990 and 2020. RESULTS: In this analysis of 769 patients with gastroesophageal adenocarcinoma, higher mGPS (0-2) scores were associated with shorter OS in the overall cohort (24.9 versus 11.9 versus 7.6 months; HR 1.74, 95% CI 1.549-1.056; p < 0.001), in locally advanced (31.1 versus 19.8 versus 13.9 months, HR 1.561, 95% CI 1.274-1.912; p < 0.001) and in advanced/metastatic settings (12.3 versus 7.3 versus 5.8 months; HR 1.377, 95% CI 1.777-1.611; p < 0.001). In multivariate analyses, the association of mGPS with the OS stayed statistically significant in the locally advanced cohort (HR 1.397, 95% CI 1.068-1.828; p = 0.015), whereas NLR, LLR, PLR and SIRI did not. mGPS was associated with more advanced stages (p < 0.001) and weight loss (p = 0.002). CONCLUSION: mGPS poses a feasible prognostic tool in patients with locally advanced gastroesophageal cancer.

OBJECTIVE: The aim of this study was to investigate the prognostic role of plasma platelet count (PLT), mean platelet volume (MPV), and the combined COP-MPV score in patients with resectable adenocarcinomas of the gastroesophageal junction. BACKGROUND: Platelet activation, quantified by PLT and elevated MPV, plays an essential part in the biological process of carcinogenesis and metastasis. An increased preoperative COP-MPV is associated with poor survival in various tumor entities. METHODS: Data of 265 patients undergoing surgical resection for adenocarcinoma of the gastroesophageal junction were abstracted. COP-MPV score was defined for each patient. Utilizing univariate and multivariate Cox proportional hazard analyses, survival was determined. RESULTS: In univariate analysis, elevated PLT (HR 3.58, 95% CI 2.61-4.80, p<0.001) and increased COP-MPV (HR 0.27, 95% CI 0.17-0.42, p<0.001 and HR 0.42, 95% CI 0.29-0.60, p<0.001) significantly correlated with shorter patients' overall and disease-free survival, for all 256 patients, as well as in the subgroups of neoadjuvantly treated (p<0.001) and primarily resected patients (p<0.001). COP-MPV remained a significant prognostic factor in multivariate analysis for OS. However, PLT alone showed significant diminished OS and DFS in all subgroups (p<0.001) in univariate and multivariate analysis. CONCLUSION: PLT is a potent independent prognostic biomarker for survival in a large prospective cohort of patients with resectable adenocarcinoma of the gastroesophageal junction. Additionally, we confirm that the COP-MPV score is significantly associated with worse outcome in these patients, but has no benefit in comparison to PLT.

BACKGROUND: Diminished systemic serum butyrylcholinesterase (BChE), a biomarker for chronic inflammation, cachexia, and advanced tumor stage, has shown to play a prognostic role in various malignancies. The aim of this study was to investigate the prognostic value of pretherapeutic BChE levels in patients with resectable adenocarcinoma of the gastroesophageal junction (AEG), treated with or without neoadjuvant therapy. METHODS: Data of a consecutive series of patients with resectable AEG at the Department for General Surgery, Medical University of Vienna, were analyzed. Preoperative serum BChE levels were correlated to clinic-pathological parameters as well as treatment response. The prognostic impact of serum BChE levels on disease-free (DFS) and overall survival (OS) was evaluated by univariate and multivariate cox regression analysis, and Kaplan-Meier curves used for illustration. RESULTS: A total of 319 patients were included in this study, with an overall mean (standard deviation, SD) pretreatment serum BChE level of 6.22 (± 1.91) IU/L. In univariate models, diminished preoperative serum BChE levels were significantly associated with shorter overall (OS, p < 0.003) and disease-free survival (DFS, p < 0.001) in patients who received neoadjuvant treatment and/or primary resection. In multivariated analysis, decreased BChE was significantly associated with shorter DFS (HR: 0.92, 95% CI: 0.84-1.00, p 0.049) and OS (HR: 0.92, 95% CI: 0.85-1.00, p < 0.49) in patients receiving neoadjuvant therapy. Backward regression identified the interaction between preoperative BChE and neoadjuvant chemotherapy as a predictive factor for DFS and OS. CONCLUSION: Diminished serum BChE serves as a strong, independent, and cost-effective prognostic biomarker for worse outcome in patients with resectable AEG who had received neoadjuvant chemotherapy.

AIM OF THE STUDY: Mean corpuscular volume (MCV) has shown mounting evidence as a prognostic indicator in a number of malignancies. The aim of this study was to examine the prognostic potential of pretherapeutic MCV among patients with pancreatic ductal adenocarcinoma (PDAC) who underwent upfront resection or resection after neoadjuvant treatment (NT). PATIENTS AND METHODS: Consecutive patients with PDAC who underwent pancreatic resection between 1997 and 2019 were included in this study. Neoadjuvantly treated patients' serum MCV was measured before NT and before surgery. In patients undergoing upfront resection serum MCV was measured before surgery. Median MCV values were used as cut-off to distinguish high from low MCV values. RESULTS: Five hundred and forty-nine (438 upfront resected and 111 neoadjuvantly treated) patients were included in this study. Multivariate analysis revealed, that high MCV before and after NT, were independent negative prognostic factors for overall survival (P<0.01, respectively). Furthermore, the median MCV value from before to after NT increased significantly (P<0.001, Wilcoxon signed-rank test) and was (P=0.03, Wilcoxon rank sum test) associated with tumor response to NT. CONCLUSION: High MCV is an independent adverse prognostic factor in patients with resectable neoadjuvantly treated PDAC and may qualify as useful indicator to help physicians to provide personalized prognostication.
RESUMO
BACKGROUND: The effects of cytotoxic chemotherapy on the expression of programmed cell death 1 (PD-1) and its ligand (PD-L1) in cancer cells and peritumoral cells are unclear. The aim of this study was to investigate the impact of neoadjuvant chemotherapy on PD-1 and PD-L1 expression in adenocarcinomas of the gastroesophageal junction. METHODS: PD-1 and PD-L1 expression in cancer cells and tumor-infiltrating lymphocytes in paired diagnostic biopsies and surgical specimens from patients with pretreated and curatively resected adenocarcinomas of the gastroesophageal junction were evaluated by immunohistochemistry. RESULTS: Paired tumor samples were available from 40 patients. PD-1 expression in cancer cells (p < 0.001; Exact Symmetry Test) and tumor-infiltrating lymphocytes (p < 0.001; Exact Symmetry Test) increased significantly after neoadjuvant therapy. Furthermore, we observed a significant decrease in PD-L1 expression in cancer cells (p = 0.003) after neoadjuvant therapy was observed. CONCLUSION: In this study we could show that tumor-cell expression of PD-1 and PD-L1 was significantly altered in patients with adenocarcinomas of the gastroesophageal junction after receiving neoadjuvant chemotherapy. Based on these observations, patients might profit from the combined use of cytotoxic chemotherapy and the blockade of the PD-1 axis.

BACKGROUND: The effects of cytotoxic chemotherapy on the expression of programmed death ligand 2 (PD-L2) are unknown and little is known about how the tumor microenvironment changes following neoadjuvant chemotherapy in locally advanced gastroesophageal adenocarcinomas (AEG). Recently, a number of studies reported that cytotoxic chemotherapy affects the expression levels of programmed cell death protein 1 (PD-1) and its ligand 1 (PD-L1). Regarding PD-L2, the second known ligand of PD1, no data on potential changes in expression patterns in patients with preoperatively treated AEG are available. The aim of this study was to investigate the impact of cytotoxic chemotherapy on PD-L2 expression in patients with resectable AEG. METHODS: Consecutive patients with locally advanced AEG treated with preoperative cytotoxic chemotherapy were included. PD-L2 expression by cancer cells (CCs) and tumor-infiltrating lymphocytes (TILs) was investigated in samples of paired diagnostic biopsies and resected tumor specimens by immunohistochemistry using two different anti-PD-L2 antibodies. RESULTS: Included were 40 patients with AEG and available paired tumor tissue samples. PD-L2 expression was observed in one diagnostic biopsy sample by CCs and in one diagnostic biopsy sample by TILs. There was no difference concerning the expression levels measured by the two antibodies. CONCLUSION: In contrast to previously published studies reporting PD-L2 expression rates of up to 50% in AEGs, in our cohort, PD-L2 expression seems to play no significant role in AEG.

OBJECTIVE: The aim of this study was to determine the clinical role of the systemic immune-inflammation index in patients with resectable adenocarcinoma of the gastroesophageal junction treated with or without neoadjuvant therapy. BACKGROUND: Adenocarcinoma of the gastroesophageal junction is an aggressive disease, with less than 20% of overall patients surviving more than 5 years after diagnosis, while currently available clinical staging for esophageal cancer is lacking necessary accuracy. The systemic immune-inflammation index (SII) based on peripheral neutrophil, lymphocyte, and platelet counts has shown a prognostic impact in various malignancies. METHODS: Data of consecutive patients undergoing esophagectomy (n = 320, 1992 to 2016) were abstracted. The cut point for high and low SII before neoadjuvant treatment and before surgery was calculated for illustration of the Kaplan-Meier curves. SII was used for the correlation with patients' clinicopathological characteristics as a continuous variable. Survival was analyzed with Cox proportional hazards models using clinical or pathological staging, adjusting for other known survival predictors. RESULTS: In both neoadjuvantly treated and primarily resected patients, high SII was significantly associated with diminished overall [hazard ratio (HR) 1.3, 95% confidence interval (95% CI) 1.2-1.4; HR 1.2, 95% CI 1.2-1.3, respectively] and disease-free survival (HR 1.3, 95% CI 1.2-1.3; HR 1.2, 95% CI 1.2-1.3, respectively). In multivariable survival analysis, SII remained an independent prognostic factor for overall survival (HR 1.3, 95% CI 1.2-1.4; HR 1.2, 95% CI 1.2-1.3, respectively) and disease-free survival (HR 1.3, 95% CI 1.2-1.3; HR 1.2, 95% CI 1.2-1.3, respectively) in primarily resected and neoadjuvantly treated patients. CONCLUSION: Elevated SII is an independent adverse prognostic factor in patients with resectable gastroesophageal adenocarcinomas with and without neoadjuvant treatment.

BACKGROUND: Electrical stimulation therapy (EST) of the lower esophageal sphincter (LES) is a novel technique in antireflux surgery. Due to the minimal alteration at the LES during surgery, LES-EST is meant to be ideal for patients with gastroesophageal reflux disease (GERD) and ineffective esophageal motility (IEM). The aim of this prospective trial (NCT03476265) is to evaluate health-related quality of life and esophageal acid exposure after LES-EST in patients with GERD and IEM. METHODS: This is a prospective non-randomized open-label study. Patients with GERD and IEM undergoing LES-EST were included. Follow-up (FUP) at 12 months after surgery included health-related quality of life (HRQL) assessment with standardized questionnaires (GERD-HRQL) and esophageal functional testing. RESULTS: According to the study protocol, 17 patients fulfilled eligibility criteria. HRQL score for heartburn and regurgitation improved from 21 (interquartile range (IQR) 15-27) to 7.5 (1.25-19), p = 0.001 and from 17 (11-23.5) to 4 (0-12), p = 0.003, respectively. There was neither significant improvement of esophageal acid exposure nor reduction of number of reflux events in pH impedance measurement. Distal contractile integral improved from 64 (11.5-301) to 115 (IQR 10-363) mmHg s cm, p = 0.249. None of the patients showed any sign of dysphagia after LES-EST. One patient needed re-do surgery and re-implantation of the LES-EST due to breaking of the lead after one year. CONCLUSION: Although patient satisfaction improved significantly after surgery, this study fails to demonstrate normalization or significant improvement of acid exposure in the distal esophagus after LES-EST.

RESUMO
PURPOSE: Long-term follow-up after sleeve gastrectomy (SG) revealed a high incidence of gastroesophageal reflux disease (GERD) frequently caused by preoperative silent pathologic reflux. We aimed to evaluate prevalence and phenotypes of GERD in asymptomatic patients with morbid obesity prior to metabolic surgery according to modern objective testing. MATERIAL AND METHODS: Prospective collection of data including consecutive patients with morbid obesity (body mass index (BMI) ≥ 35 kg/m2) prior to metabolic surgery was applied for this study between 2014 and 2019. Patients underwent clinical examinations, endoscopy, pH metry, and high-resolution manometry and were analyzed according to the Lyon consensus. RESULTS: Of 1379 patients undergoing metabolic surgery, 177 (12.8%, females = 105) asymptomatic individuals with a median age of 42.6 (33.8; 51.6) years and a median BMI of 44.6 (41.3; 50.8) kg/m2 completed objective testing and were included during the study period. GERD was diagnosed in 55 (31.1%), whereas criteria of borderline GERD were met in another 78 (44.1%). GERD was mediated by a structural defective lower esophageal sphincter (p = 0.004) and highlighted by acidic (p = 0.004) and non-acidic (p = 0.022) reflux episodes. Esophageal motility disorders were diagnosed in 35.6% (n = 63) of individuals with a novel hypercontractile disorder found in 7.9% (n = 14) of patients. CONCLUSION: GERD affects a majority of asymptomatic patients with morbid obesity prior to primary bariatric surgery. Future longitudinal trials will have to reveal the clinical significance of esophageal motility disorders in patients with morbid obesity.

RESUMO
BACKGROUND: The clinical behaviour and outcome of young patients with gastroesophageal tumours (GET) is surmised to differ from older patients, yet data on the comparison of these two patient subgroups is scarce. This study focuses on the investigation of the clinical characteristics and survival outcome of younger-age people with GET, when compared to older patients. METHODS: Patients diagnosed with GET at the Medical University of Vienna between 2004 and 2016 were included in this study. Clinical parameters and the overall survival (OS) were compared between young (≤ 45 years) and elderly (≥ 65 years) patients. RESULTS: Among 796 patients, who were eligible for this analysis, fifty-eight patients (7%) were ≤ 45 years at the initial onset of the disease. These 58 young patients were then matched to elderly patients based on the gender, tumour stage, histology and tumour location. The number of metastatic lesions was significantly higher among young patients (p < 0.05). In a non-metastatic setting younger patients showed a significant longer OS than older patients (median 1226 versus 801 days, p = 0.028). Furthermore, young patients with extensive metastatic disease (2 or more metastatic site) had a significantly poorer OS than elderly patients (median 450 versus 646 days, p = 0.033). CONCLUSION: These results indicate that young patients might be diagnosed very late, which might lead to the development of a more aggressive disease compared to older patients, but a relatively long OS when diagnosed and treated in a non-metastatic setting. Thus, screening methods for younger patients might be considerable to enhance the outcome of young patients with GET.

Immunotherapy with check-point inhibitors serves as a promising treatment strategy in patients with upper gastrointestinal (GI) tumors. Human epidermal growth factor receptor 2 (HER2) is the only identified therapeutic target in upper GI tumors, whose potential interaction with programmed death-ligand 1 (PD-L1) is unknown. The aim of this study was the investigation of PD-L1 and HER2 in upper GI tumors. We retrospectively identified patients with HER2 positive gastroesophageal cancers and matched them with a HER2 negative group. We investigated the tumor specimens for HER2 status and PD-L1 expression, with the following assessments being performed: i) staining of tumor cells in terms of tumor proportion score (TPS), ii) staining for tumor-associated immune cells (TAIs), iii) interface pattern and iv) combined positive score (CPS). Both HER2 positive and negative group consisted of 59 patients. Expression of PD-L1 in TAIs and interface pattern were associated with a favorable outcome (p = 0.02, HR = 0.8; p = 0.04, HR = 0.39; respectively) in patients with localized disease, whereas TPS was associated with an unfavorable outcome in patients with advanced tumor (p = 0.02, HR = 1.4). These effects were HER2 independent. PD-L1 expression in its different assessment is equally observed in HER2 positive and negative patients. Future studies will show whether dual inhibition of HER2 and PD-L1 improves survival of this selected patient population.

INTRODUCTION: The prognostic value of symptoms at disease presentation of advanced gastro-oesophageal cancer is unknown. Thus, the aim of this study was to characterise these symptoms and correlate them with the outcome, so new prognostic markers can be defined. METHODS: We analysed clinical data including symptoms, therapies and survival of patients with stage IV gastro-oesophageal cancer treated between 2002 and 2018 at the Vienna General Hospital, Austria. Initial symptoms as well as stenosis in endoscopy and HER2 positivity were evaluated in a cross-validation model to ascertain the impact of each variable on patient survival. RESULTS: In total, 258 patients were evaluated. Five factors (stenosis in endoscopy, weight loss, HER2 positivity, dyspepsia, ulcer or active bleeding) have proven to be statistically relevant prognostic factors and were given a count of +1 and -1, if applicable. The resulting score ranges between -3 and +2. The survival probability for 180 days with a score of -3/-2, -1, 0, +1 and +2 is 90%, 80%, 73%, 72% and 42%, whereas for 2 years, it is 30%, 30%, 8%, 7% and 3%, respectively. The median overall survival of a score of -3/-2, -1, 0, +1 and +2 was 579 (95% CI 274 to not measurable), 481 (95% CI 358 to 637), 297 (95% CI 240 to 346), 284 (95% CI 205 to 371), 146 (95% CI 120 to 229) days, respectively. CONCLUSION: The data from this retrospective study indicate that the Viennese risk prediction score for Advanced Gastroesophageal carcinoma based on Alarm Symptoms score provides independent prognostic information that may support clinical decision making at diagnosis of advanced gastro-oesophageal cancer. Our findings should be evaluated in prospective studies.

PURPOSE: Neoadjuvant radiochemotherapy (RCTH) is proven to be highly effective in the treatment of esophageal cancer (EC). We investigated oncological outcome and morbidity in patients treated with a modified CROSS protocol followed by esophagectomy at our institution. METHODS: Patients with EC receiving neoadjuvant RCTH with paclitaxel and carboplatin and concurrent radiotherapy (46â¯Gy) followed by esophagectomy were included in this retrospective analysis. Histopathological response, overall survival (OS) and recurrence-free interval (RFI) as well as perioperative morbidity were investigated. RESULTS: Thirty-six patients (86.1% male, mean age 61.3 years, standard deviation 11.52) received neoadjuvant RCTH before surgery. Sixteen patients (44.4%) were treated for squamous cell cancer, whereas 20 patients (55.6%) had adenocarcinoma. The majority (75%) underwent abdominothoracic esophageal resection. Major complications occurred in 7 patients (19.5%) including anastomotic leakage in 4 patients (11.1%). A R0 resection was achieved in 97.2%. A complete pathological remission was seen in 13 patients (36.1%). Major response, classified as Mandard tumor regression grade 1 and 2, was found in 26 patients (72.2%). Median OS and RFI were not reached. CONCLUSIONS: Neoadjuvant radiotherapy with 46â¯Gy and concomitant chemotherapy with paclitaxel and carboplatin for the treatment of locally advanced esophageal carcinoma is safe and effective. The results of this modified radiotherapy protocol are encouraging and should be considered in future patient treatment and study designs.

BACKGROUND/AIM: A standard treatment recommendation for advanced stage gastroesophageal cancer is still missing. PATIENTS AND METHODS: We retrospectively analyzed clinical data of patients with inoperable locally advanced or metastatic gastroesophageal cancer treated between 2001 and 2017 at the Vienna General Hospital, Austria. RESULTS: Administration of systemic therapy was positively associated with overall survival (OS) (469 days vs. 185 days; p<0.001), while palliative gastrectomy or radiotherapy showed no correlation. OS was significantly longer in patients receiving capecitabine/oxaliplatin (XELOX) vs. leucovorin/5-FU/oxaliplatin (FOLFOX) (600 days vs. 327 days, p<0.05). Comparison of doublet vs. triplet chemotherapies showed no difference in OS, but triplet chemotherapy resulted in more adverse events. The anti-HER2-antibody trastuzumab doubled OS (836 days vs. 399 days, p=0.053). CONCLUSION: Capecitabine may be preferably used over infused 5-FU and doublet chemotherapy over triplet chemotherapy in the first-line palliative setting of advanced gastroesophageal cancer.
