World J Surg Oncol 2019; 17:3. [PMID: 30606195 PMCID: PMC6317221 DOI: 10.1186/s12957-018-1534-z] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2018] [Accepted: 11/28/2018] [Indexed: 02/07/2023] Open
Abstract
Background Although pathological evaluation has been considered an effective evaluation method, some problems still exist in practice. Therefore, we explored whether there are more reasonable and practical pathological evaluation criteria for neoadjuvant chemotherapy in patients with advanced gastric cancer. Here, we aim to determine pathological judgment criteria for neoadjuvant chemotherapy in patients with advanced gastric cancer. Methods Eighty-seven patients with cT2–4 or cN+ were enrolled in this study. Pathological factors for overall survival (OS) were investigated using univariate and multivariate analyses, and the pathological criteria for neoadjuvant chemotherapy were then determined. Results A total of 87 patients underwent 3–4 cycles of neoadjuvant chemotherapy, with 67 (77.0%), 15 (17.2%), and 5 (5.8%) receiving Folfox6, Xelox, and SOX regimens, respectively. All patients showed different levels of graded histological regression (GHR) of the primary tumor, with a ≥ 50% regression rate of 50.6%. The univariate analysis showed that GHR ≥ 50% (p = 0.022), 66.7% (p = 0.013), and 90% (p = 0.028) were significantly correlated with OS. The multivariate analysis demonstrated that ypTNM (II/III) stage was significantly associated with OS compared with ypTNM (0+I) stage [HR = 3.553, 95% CI 1.886–6.617; HR = 3.576, 95% CI 1.908–6.703, respectively] and that the Lauren classification of diffuse type was also an independent risk factor for OS compared with the intestinal type (HR = 3.843, 95% CI 1.443–10.237). Conclusions The Lauren classification and ypTNM stage after neoadjuvant chemotherapy are independent prognostic factors in advanced gastric cancer. A GHR ≥ 50%/< 50% can be used as the primary criterion for advanced gastric cancer after neoadjuvant chemotherapy to determine postoperative adjuvant chemotherapy regimens.

Thoracoabdominal versus transhiatal surgical approaches for adenocarcinoma of the esophagogastric junction-a systematic review and meta-analysis. Langenbecks Arch Surg 2019; 404:103-113. [PMID: 30607534 DOI: 10.1007/s00423-018-1745-3] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2018] [Accepted: 12/10/2018] [Indexed: 01/28/2023]
Abstract
PURPOSE The aim of this systematic review and meta-analysis was to compare the oncological and perioperative outcomes of transhiatally extended gastrectomy (TEG) and thoracoabdominal esophagectomy (TAE) for therapy of adenocarcinomas of the esophagogastric junction (AEG) with focus on AEG type II, as the optimal approach for these tumors is still unclear. METHODS MEDLINE, EMBASE, and the Cochrane Library (CENTRAL) were searched until July 24, 2018. Studies comparing TAE and TEG for surgical treatment of AEG type tumors have been included. Patient's baseline and perioperative data have been extracted and meta-analyses have been conducted for the outcomes: number of dissected lymph nodes, R0-resection rate, anastomotic leak rate, postoperative morbidity, and 30-day mortality. RESULTS Of 6709 articles identified, 8 studies have been included for further analysis. One thousand thirty-four patients underwent TAE, and 1177 patients TEG. No differences were found between the approaches in regard to number of dissected lymph nodes (MD - 0.96; 95% CI - 3.07 to 1.15; p = 0.37), R0-resection rates (OR 0.97; 95% CI 0.57 to 1.63; p = 0.90), anastomotic leak rates (OR 1.13; 95% CI 0.69 to 1.86; p = 0.63), and 30-day mortality (OR 1.53; 95% CI 0.90 to 2.61; p = 0.11). However, a higher rate of postoperative morbidity was found after TAE (OR 1.55; 95% CI 1.12 to 2.14; p = 0.008). CONCLUSIONS The optimal approach to surgical therapy of AEG II still remains unclear. This study identified a significantly higher rate of postoperative morbidity after TAE at comparable surgical outcomes. Due to major limitations concerning the quality of included studies, current data strongly mandates a properly designed randomized controlled trial to identify the optimal surgical approach for AEG type II tumors.

Lymph node regression and survival following neoadjuvant chemotherapy in oesophageal adenocarcinoma. Br J Surg 2018; 105:1639-1649. [PMID: 30047556 DOI: 10.1002/bjs.10900] [Citation(s) in RCA: 49] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2018] [Revised: 04/12/2018] [Accepted: 05/03/2018] [Indexed: 12/11/2022]
Abstract
BACKGROUND The aim was to define the pathological response in lymph nodes following neoadjuvant chemotherapy for oesophageal adenocarcinoma and to quantify any associated survival benefit. METHODS Lymph nodes retrieved at oesophagectomy were examined retrospectively by two pathologists for evidence of a response to chemotherapy. Patients were classified as lymph node-negative (either negative nodes with no evidence of previous tumour involvement or negative with evidence of complete regression) or positive (allocated a lymph node regression score based on the proportion of fibrosis to residual tumour). Lymph node responders (score 1, complete response; 2, less than 10 per cent remaining tumour; 3, 10-50 per cent remaining tumour) and non-responders (score 4, more than 50 per cent viable tumour; 5, no response) were compared in survival analyses using Kaplan-Meier and Cox regression analysis. RESULTS Among 377 patients, 256 had neoadjuvant chemotherapy. Overall, 68 of 256 patients (26·6 per cent) had a lymph node response and 115 (44·9 per cent) did not. The remaining 73 patients (28·5 per cent) had negative lymph nodes with no evidence of regression. Some patients had a lymph node response in the absence of a response in the primary tumour (27 of 99, 27 per cent). Lymph node responders had a significant survival benefit (P < 0·001), even when stratified by patients with or without a response in the primary tumour. On multivariable analysis, lymph node responders had decreased overall (hazard ratio 0·53, 95 per cent c.i. 0·36 to 0·78) and disease-specific (HR 0·42, 0·27 to 0·66) mortality, and experienced reduced local and systemic recurrence. CONCLUSION Lymph node regression is a strong prognostic factor and may be more important than response in the primary tumour.

Abstract
BACKGROUND Prognostic differences between pTN- and ypTN-categories and the prognostic accuracy of the 8th edition UICC-pTNM- and AJCC-ypTNM-staging-system for esophageal and gastric adenocarcinoma are unclear. METHODS We retrospectively analyzed data of 740 patients with esophagogastric adenocarcinoma, who underwent curative surgery (344 after neoadjuvant treatment [NT]) at our institution. Survival analyses were performed according to Kaplan-Meier (log-rank test). Multivariate analyses were performed using the Cox proportional hazard model. RESULTS Low ypT-categories did not discriminate overall survival (ypT0: reference; ypT1: HR1.0/p = 0.909; ypT2: HR0.9/p = 0.845; ypT3: HR1.5/p = 0.184; ypT4: HR2.8/p = 0.004) and no difference was found between ypN1- and ypN2-disease (ypN0: HR0.4/p < 0.001; ypN1: reference; ypN2: HR1.1/p = 0.653; ypN3: HR1.7/p = 0.014). In esophageal adenocarcinoma the UICC-TNM- and AJCC-ypTNM-staging-system was able to predict survival for patients after NT, while in gastric cancer it failed to provide sufficient prognostic information. A simplified staging system provided better stratification after NT and was an independent prognosticator for both esophageal and gastric adenocarcinoma (stage I: reference; stage II: HR2.2/p = 0.005; stage III: HR4.1/p < 0.001). CONCLUSION Prognostic value of ypTN-categories seems limited. After NT the current UICC/AJCC-staging-system is able to predict survival in esophageal adenocarcinoma, but needs to be reevaluated in gastric cancer patients and modified if needed. A novel simplified staging system might be more practicable for patients after NT.

Abstract
BACKGROUND Only a few studies have analyzed multimodal treatment concepts in the subgroup of signet-ring-cell containing upper gastrointestinal (GI) cancer. Recent retrospective, multicentric data favor primary resection without neoadjuvant chemotherapy for gastric signet-ring-cell containing carcinomas (SRCs). We compared the outcomes of primarily resected carcinomas with neoadjuvantly treated, locally advanced esophagogastric SRCs. METHODS A total of 310 patients with esophagogastric SRC-staged cT3/4/Nany/Many from a prospective unicentric database were included in this study; 192 (61.9%) received neoadjuvant therapy (NEO group) and 118 (38.1%) were primarily resected (RES group). RESULTS Overall, 128 (41.3%) patients presented with adenocarcinoma of the esophagogastric junction (AEG) and 182 (58.7%) presented with gastric cancer. Neoadjuvant therapy was significantly associated with resection in curative intent (NEO: 91.1%; RES: 75.4%; P = 0.001), improved (y)pT category (P = 0.035), improved (y)pN category (P < 0.001), and R0 resections (curative intent cohort: 76.0% in NEO vs. 60.7% in RES; P = 0.010), among others, but not with postoperative complications. Overall survival was significantly improved by neoadjuvant treatment {median survival 28.5 months (95% confidence interval [CI] 14.4-39.6) vs. RES: 14.9 months (10.6-17.5); P < 0.001}, as well as in subgroups (AEG and gastric tumors, R0-resected patients, and patients with and without relevant comorbidities). Independent prognostic factors were neoadjuvant therapy (hazard ratio [HR] 0.66; P = 0.023), pT4 category (HR 1.71; P = 0.041), pN2 category (HR 1.86; P = 0.013), pN3 category (HR 2.40; P < 0.001), pM1 category (HR 1.95; P = 0.003), age > 70 years (HR 1.79; P = 0.006), gastric localization (HR 0.69; P = 0.032), American Society of Anesthesiologists classification 3/4 (HR 1.71; P = 0.004), and incomplete resection R1/2 (HR 1.6; P = 0.014). CONCLUSIONS Our results demonstrate a survival advantage for advanced-stage esophagogastric SRC patients by neoadjuvant treatment.

Abstract
BACKGROUND To date there is no evidence that more intensive follow-up after surgery for esophagogastric adenocarcinoma translates into improved survival. This study aimed to evaluate the impact of standardized surveillance by a specialized center after resection on survival. METHODS Data of 587 patients were analyzed who underwent curative surgery for esophagogastric adenocarcinoma in our institution. Based on their postoperative surveillance, patients were assigned to either standardized follow-up (SFU) by the National Center for Tumor Diseases (SFU group) or individual follow-up by other physicians (non-SFU group). Propensity score matching (PSM) was performed to compensate for heterogeneity between groups. Groups were compared regarding clinicopathological findings, recurrence, and impact on survival before and after PSM. RESULTS Of 587 patients, 32.7% were in the SFU and 67.3% in the non-SFU group. Recurrence occurred in 39.4% of patients and 92.6% within the first 3 years; 73.6% were treated, and of those 17.1% underwent resection. In recurrent patients overall and post-recurrence survival (OS/PRS) was influenced by diagnostic tools (p < 0.05), treatment (p ≤ 0.001), and resection of recurrence (p ≤ 0.001). Standardized follow-up significantly improved OS (84.9 vs. 38.4 months, p = 0.040) in matched analysis and was an independent positive predictor of OS before and after PSM (p = 0.034/0.013, respectively). CONCLUSION After PSM, standardized follow-up by a specialized center significantly improved OS. Cross-sectional imaging and treatment of recurrence were associated with better outcome. Regular follow-up by cross-sectional imaging especially during the first 3 years should be recommended by national guidelines, since early detection might help select patients for treatment of recurrence and even resection in few designated cases.

Abstract
Background Esophageal cancer is often marked by aggressive tumor growth and poor prognosis. Patient groups who benefit from perioperative therapy are not yet defined. The tumor microenvironment and circulating factors as possible predictors of response and prognosis gain interest. This study aimed to investigate cytokines in patients’ serum and tumor tissue with regard to response and prognosis. Results Median survival between SCC and AC was not different (published previously). Lower levels of CCL11 (Eotaxin-1) and CXCL10 (IP-10) in the tumor tissue were associated with a better prognosis (p = 0.022; p = 0.002). In the AC subgroup higher concentrations of TGF-β3 in serum and corresponding tumor tissue were associated with adverse prognosis (p = 0.035; p = 0.006). An association with histopathological response was found for IL-12(p70) and CXCL10 in patients’ sera (p = 0.041; p = 0.032). The tissue levels of TGF-β1 and TGF-β2 were significantly lower in histopathological responders than in nonresponders (p = 0.033; p = 0.007). A similar trend was seen for TGF-β3, without statistical significance (p = 0.097). Materials and Methods Preoperative serum samples and corresponding tumor tissue (n = 54), only serum (n = 20) or only tissue (n = 4) were collected from patients undergoing surgery for cT3/4 esophageal squamous cell cancer (SCC) (n = 34) and adenocarcinoma (AC) (n = 44). All samples were taken after neoadjuvant treatment. All patients received perioperative chemo(radio)therapy. Cytokine levels of 17 different cytokines were measured by multiplex immunoassay and correlated with clinicopathological factors. Conclusions Two chemokines (CCL11 and CXCL10) in posttherapeutic tumor tissue were associated with prognosis in patients with esophageal cancer, lower levels indicating a better prognosis. Lower levels of TGF-β were associated with better response and prognosis in patients with AC.

Gastric Cancer Maximum Tumour Diameter Reduction Rate at CT Examination as a Radiological Index for Predicting Histopathological Regression after Neoadjuvant Treatment: A Multicentre GIRCG Study. Gastroenterol Res Pract 2018; 2018:1794524. [PMID: 29736166 PMCID: PMC5875045 DOI: 10.1155/2018/1794524] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2017] [Accepted: 12/24/2017] [Indexed: 12/20/2022] Open
Abstract
Aim To investigate the role of maximum tumour diameter (D-max) reduction rate at CT examination in predicting histopathological tumour regression grade (TRG according to the Becker grade), after neoadjuvant chemotherapy (NAC), in patients with resectable advanced gastric cancer (AGC). Materials and Methods Eighty-six patients (53 M, mean age 62.1 years) with resectable AGC (≥T3 or N+), treated with NAC and radical surgery, were enrolled from 5 centres of the Italian Research Group for Gastric Cancer (GIRCG). Staging and restaging CT and histological results were retrospectively reviewed. CT examinations were contrast enhanced, and the stomach was previously distended. The D-max was measured using 2D software and compared with Becker TRG. Statistical data were obtained using “R” software. Results The interobserver agreement was good/very good. Becker TRG was predicted by CT with a sensitivity and specificity, respectively, of 97.3% and 90.9% for Becker 1 (D-max reduction rate > 65.1%), 76.4% and 80% for Becker 3 (D-max reduction rate < 29.9%), and 70.8% and 83.9% for Becker 2. Correlation between radiological and histological D-max measurements was strongly confirmed by the correlation index (c.i.= 0.829). Conclusions D-max reduction rate in AGC patients may be helpful as a simple and reproducible radiological index in predicting TRG after NAC.

Surgical strategies in true adenocarcinoma of the esophagogastric junction (AEG II): thoracoabdominal or abdominal approach? Gastric Cancer 2018; 21:303-314. [PMID: 28685209 DOI: 10.1007/s10120-017-0746-1] [Citation(s) in RCA: 62] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2017] [Accepted: 06/06/2017] [Indexed: 02/07/2023]
Abstract
BACKGROUND The optimal surgical approach for adenocarcinoma directly at the esophagogastric junction (AEG II) is still under debate. This study aims to evaluate the differences between right thoracoabdominal esophagectomy (TAE) (Ivor-Lewis operation) and transhiatal extended gastrectomy (THG) for AEG II. METHODS From a prospective database, 242 patients with AEG II (TAE, n = 56; THG, n = 186) were included and analyzed according to characteristics and perioperative morbidity and mortality and overall survival (chi-square, Mann-Whitney U, log-rank, Cox regression). RESULTS Groups were comparable at baseline with exception of age. Patients older than 70 years were more frequently resected by THG (p = 0.003). No differences in perioperative morbidity (p = 0.197) and mortality (p = 0.711) were observed, including anastomotic leakages (p = 0.625) and pulmonary complications (p = 0.494). There was no significant difference in R0 resection (p = 0.719) and number of resected lymph nodes (p = 0.202). Overall median survival was 38.4 months. Survival after TAE was significantly longer than after THG (median OS not reached versus 33.6 months, p = 0.02). Multivariate analysis revealed pN-category (p < 0.001) and type of surgery (p = 0.017) as independent prognostic factors. The type of surgery was confirmed as prognostic factor in locally advanced AEG II (cT 3/4 or cN1), but not in cT1/2 and cN0 patients. CONCLUSIONS Our single-center experience suggests that patients with (locally advanced) AEG II tumors may benefit from TAE compared to THG. For further evaluation, a randomized trial would be necessary.

Pilot study of serial FLT and FDG-PET/CT imaging to monitor response to neoadjuvant chemoradiotherapy of esophageal adenocarcinoma: correlation with histopathologic response. Ann Nucl Med 2018; 32:165-174. [PMID: 29332233 DOI: 10.1007/s12149-018-1229-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2017] [Accepted: 01/04/2018] [Indexed: 11/27/2022]
Abstract
OBJECTIVE The aim of this prospective pilot study was to investigate the potential of serial FLT-PET/CT compared to FDG-PET/CT to provide an early indication of esophageal cancer response to concurrent neoadjuvant chemoradiation therapy. METHODS Five patients with biopsy-proven esophageal adenocarcinomas underwent neoadjuvant chemoradiation (Tx) prior to minimally invasive esophagectomy. The presence of residual tumor was classified histologically using the Mandard et al. criteria, categorizing patients as pathologic responders and non-responders. Participants underwent PET/CT imaging 1 h after intravenous administration of FDG and of FLT on two separate days within 48 h of each other. Each patient underwent a total of 3 scan "pairs": (1) pre-treatment, (2) during treatment, and (3) post-treatment. Image-based response to therapy was measured in terms of changes in SUVmax (ΔSUV) between pre- and post-therapeutic FLT- and FDG-PET scans. The PET imaging findings were correlated with the pathology results after surgery. RESULTS All tumors were FDG and FLT avid at baseline. Lesion FLT uptake was lower than with FDG. Neoadjuvant chemoradiation resulted in a reduction of tumor uptake of both radiotracers in pathological responders (n = 3) and non-responders (n = 2). While the difference in the reduction in mean tumor FLT uptake during Tx between responders (ΔSUV = - 55%) and non-responders (ΔSUV = - 29%) was significant (P = 0.007), for FDG it was not, [responders had a mean ΔSUV = - 39 vs. - 31% for non-responders (P = 0.74)]. The difference in the reduction in tumor FLT uptake at the end of treatment between responders (ΔSUV = - 62%) and non-responders (ΔSUV = - 57%) was not significant (P = 0.54), while for FDG there was a trend toward significance [ΔSUV of responders = - 74 vs. - 52% in non-responders (P = 0.06)]. CONCLUSION The results of this prospective pilot study suggest that early changes in tumor FLT uptake may be better than FDG in predicting response of esophageal adenocarcinomas to neoadjuvant chemoradiation. These preliminary results support the need to corroborate the value of FLT-PET/CT in a larger cohort.

Abstract
AIM To review the current understanding of signet-ring type oesophageal adenocarcinoma including evidence for prognosis. METHODS We conducted a literature search of nine healthcare literature databases for articles detailing the biology and clinical outcomes of signet-ring cell adenocarcinoma of the oesophagus. The impact of signet-ring cell morphology was analysed and detailed in written text and tabular format. Current understanding of the biology of signet-ring cell adenocarcinoma of the oesophagus was summarised. RESULTS Signet-ring cell carcinoma was represented in 7.61% of the 18 989 cases of oesophageal carcinoma reviewed in multiple studies. The presence of signet-ring cells conferred a worse prognosis and these tumours responded differently to conventional treatments as compared with typical adenocarcinoma. Little is known about the biological features of signet-ring cell adenocarcinoma of the oesophagus. Work in gastric lesions has identified potential targets for future treatments such as CDH1 and RHOA genes. Categorisation of signet-ring cell carcinomas by the proportion of signet-ring cells within tumours differs among clinicians despite WHO criteria for classification. The current UK guidelines for histopathological reporting of oesophageal tumours do not emphasise the importance of identifying signet-ring cells. CONCLUSION The presence of signet-ring cells in oesophageal adenocarcinomas leads to poorer clinical outcomes. Current understanding of signet-ring cell biology in oesophageal cancer is limited.

Abstract
BACKGROUND To verify the prognostic value of the pathologic and radiological tumor response after neoadjuvant chemotherapy in the treatment of locally advanced gastric adenocarcinoma. METHODS A total of 67 patients with locally advanced gastric cancer (clinical ≥ T2 or nodal disease and without evidence of distant metastases) underwent perioperative chemotherapy (ECF or ECX regimen) from December 2009 through June 2015 in two surgical units. Histopathological and radiological response to chemotherapy were evaluated by using tumor regression grade (TRG) (Becker's criteria) and volume change assessed by CT. RESULTS Fifty-one (86%) patients completed all chemotherapy scheduled cycles successfully and surgery was curative (R0) in 64 (97%) subjects. The histopathological analysis showed 19 (29%) specimens with TRG1 (less than 10% of vital tumor left) and 25 (37%) patients had partial or complete response (CR) assessed by CT scan. Median disease free survival (DFS) and overall survival (OS) were 25.70 months (range, 14.52-36.80 months) and 36.60 months (range, 24.3-52.9 months), respectively. The median follow up was 27 months (range, 5.00-68.00 months). Radiological response and TRG were found to be a prognostic factor for OS and DFS, while tumor histology was not significantly related to survival. CONCLUSIONS Both radiological response and TRG have been shown as promising survival markers in patients treated with perioperative chemotherapy for locally advanced gastric cancer. Other predictive markers of response to chemotherapy are strongly required.

Abstract
Neoadjuvant therapy has been successfully introduced in the treatment of locally advanced gastrointestinal malignancies, particularly esophageal, gastric, and rectal cancers. The effects of preoperative chemo- or radiochemotherapy can be determined by histopathological investigation of the resection specimen following this treatment. Frequent histological findings after neoadjuvant therapy include various amounts of residual tumor, inflammation, resorptive changes with infiltrates of foamy histiocytes, foreign body reactions, and scarry fibrosis. Several tumor regression grading (TRG) systems, which aim to categorize the amount of regressive changes after cytotoxic treatment in primary tumor sites, have been proposed for gastroesophageal and rectal carcinomas. These systems primarily refer to the amount of therapy-induced fibrosis in relation to the residual tumor (e.g., the Mandard, Dworak, or AJCC systems) or the estimated percentage of residual tumor in relation to the previous tumor site (e.g., the Becker, Rödel, or Rectal Cancer Regression Grading systems). TRGs provide valuable prognostic information, as in most cases, complete or subtotal tumor regression after neoadjuvant treatment is associated with better patient outcomes. This review describes the typical histopathological findings after neoadjuvant treatment, discusses the most commonly used TRG systems for gastroesophageal and rectal carcinomas, addresses the limitations and critical issues of tumor regression grading in these tumors, and describes the clinical impact of TRG.

Abstract
AIMS To propectively reveal the clinicopathological and prognostic significances of monocyte-lymphocyte ratio (MLR), neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) in resected patients with non-metastatic Siewert type II/III adenocarcinoma of esophagogastric junction (AEG). METHODS A total of 611 patients diagnosed with Siewert type II/III AEG and undergoing surgery between 2006 and 2011 were prospectively followed-up until April 2016. Associations between preoperative peripheral MLR, NLR, and PLR and clinicopathological parameters were quantified using the multivariate Logistic regression model with adjustment. The correlation between the 3 ratios and cancer-specific survival (CSS) was investigated using the univariate and adjusted multivariate Cox regression models with stratifications. The periodical survival rates for the low- and high-level arms were obtained using the Kaplan-Meier method. RESULTS We set the medians (0.223, 2.22, and 124.4) as the cut-off values of preoperative MLR, NLR, and PLR, respectively. MLR was higher in male patients and those > 63 years; PLR was higher in patients with type II tumors. The (marginally-)significantly inverse ratio-CSS association was detected in male patients, those ≤ 63 years, those with type III tumors, and those with pTNM stage III tumors for MLR, and in female patients, those > 63 years, those with type III tumors, those with vessel invasion, and those with stage III tumors for NLR, but was generally negative concerning PLR. The association majorly existed in type III and pTNM stage III tumors. CONCLUSION MLR and NLR might be prognostic factors for patients with non-metastatic Siewert type II/III AEG, while PLR had limited significance.

Abstract
Perioperative chemotherapy improves overall survival in patients with oesophagogastric adenocarcinoma (OAC) and locoregional disease. The mainstay of perioperative chemotherapy in these patients is a platinum/fluoropyrimidine combination. The phase III FLOT4 trial has shown that the FLOT triplet regimen (oxaliplatin, infusional 5-FU, and docetaxel) improves the outcome of patients with OAC and locoregional disease as compared to the ECF triplet (epirubicin, cisplatin, and infusional 5-FU). Targeted therapies have currently no role in the perioperative setting for the treatment of patients with OAC. For patients with oligometastatic disease, upfront gastrectomy followed by chemotherapy did not show any survival benefit compared with chemotherapy alone and thus should be discouraged. Whether surgery should be offered to patients with metastatic OAC achieving a systemic control after upfront chemotherapy is under scrutiny in the phase III FLOT5/Renaissance trial. After neoadjuvant treatment, lymph node status but not pathologic tumor response is an independent factor in the prediction of overall survival. Growing evidence suggests that perioperative chemotherapy may be associated with an increased mortality risk in patients with microsatellite instable (MSI)/mismatch repair-deficient (MMRD) adenocarcinoma, thus validating poor responsiveness to chemotherapy in MSI patients with locoregional disease.

Abstract
The prognostic impact of lymph node (LN) metastases in gastric cancer is generally accepted. In primarily resected patients the pN-category and LN ratio are independent prognostic factors. Number of involved LNs, number of resected LNs, lymphangiosis and micrometastases also influence the prognosis significantly. To guarantee a proper D2 lymphadenectomy (LAD) at least 25 LNs according to the German S3 guidelines for the treatment of gastric cancer should be removed. Also in neoadjuvantly treated patients the ypN-category and LN ratio play an important prognostic role, despite the fact that UICC staging system was development based only on primarily resected patients. The role of response of LNs in neoadjuvantly treated patients is still unclear and needs further investigation. It seems to be less important than the response of the primary tumor. Limited data exists, suggesting that preoperative treatment might reduce the number of LNs involved and improve ypN-category. Due to further development in gastric cancer like laparoscopic resection and effective perioperative treatment in locally advanced tumor the role and the prognostic impact of LAD is again in the focus of discussion.

Abstract
Gastric cancer is the fifth (men) and sixth (women) most common cause of cancer-related death in Germany. Despite a declining incidence of distal gastric cancer, the prognosis remains dismal: the 5‑year survival rate ranges between 35% for women and 31% for men. The majority are adenocarcinomas, which occur sporadically, familial or hereditary. Adenomas and intraepithelial neoplasms are considered as precursor lesions. Recently, whole genome sequencing and comprehensive molecular profiling described four molecular subtypes of gastric cancer: Epstein-Barr virus (EBV) positive, microsatellite unstable, chromosomal unstable and genomically stable gastric cancer. Currently, only the TNM classification has stood the test of time for the assessment of patient prognosis. Neuroendocrine tumor types 1-3 and soft tissue tumors occur significantly less often in the stomach. Gastrointestinal stromal tumors and inflammatory fibroid polyps are among the more common soft tissue tumors of the stomach and show distinct phenotypes. This review gives an overview of the current World Health Organization (WHO) classification of gastric tumors.

Abstract
PURPOSE The Medical Research Council Adjuvant Gastric Infusional Chemotherapy (MAGIC) trial established perioperative epirubicin, cisplatin, and fluorouracil chemotherapy as a standard of care for patients with resectable esophagogastric cancer. However, identification of patients at risk for relapse remains challenging. We evaluated whether pathologic response and lymph node status after neoadjuvant chemotherapy are prognostic in patients treated in the MAGIC trial. MATERIALS AND METHODS Pathologic regression was assessed in resection specimens by two independent pathologists using the Mandard tumor regression grading system (TRG). Differences in overall survival (OS) according to TRG were assessed using the Kaplan-Meier method and compared using the log-rank test. Univariate and multivariate analyses using the Cox proportional hazards method established the relationships among TRG, clinical-pathologic variables, and OS. RESULTS Three hundred thirty resection specimens were analyzed. In chemotherapy-treated patients with a TRG of 1 or 2, median OS was not reached, whereas for patients with a TRG of 3, 4, or 5, median OS was 20.47 months. On univariate analysis, high TRG and lymph node metastases were negatively related to survival (Mandard TRG 3, 4, or 5: hazard ratio [HR], 1.94; 95% CI, 1.11 to 3.39; P = .0209; lymph node metastases: HR, 3.63; 95% CI, 1.88 to 7.0; P < .001). On multivariate analysis, only lymph node status was independently predictive of OS (HR, 3.36; 95% CI, 1.70 to 6.63; P < .001). CONCLUSION Lymph node metastases and not pathologic response to chemotherapy was the only independent predictor of survival after chemotherapy plus resection in the MAGIC trial. Prospective evaluation of whether omitting postoperative chemotherapy and/or switching to a noncross-resistant regimen in patients with lymph node-positive disease whose tumor did not respond to preoperative epirubicin, cisplatin, and fluorouracil may be appropriate.

Abstract
BACKGROUND The clinical value and prognostic implications of histologic response to neoadjuvant chemotherapy in gastric cancer is unknown. METHODS Tumor regression grade (TRG) was recorded in 58 gastric cancer patients identified from two institutional surgical databases. TRG 1a/b represented histologic responders (<10% viable tumor), while TRG 2/3 represented non-responders (>10% viable tumor). RESULTS TRG 1a/b was recorded in 10 patients (17%), while 48 patients (83%) had a TRG 2/3 response. Larger tumor size (OR 0.24; 95%CI 0.09, 0.64; P = 0.004) and clinical downstaging (OR 30.0; 95%CI 3.26, 276; P = 0.003) were the only factors predictive of histologic response. TRG 1a/b responders had 3-year survival of 70.0% and an estimated overall survival of >69.8 months compared to 38.2% and 22.8 months in non-responders; however, this trend was not statistically significant (P = 0.535). While TRG could not predict survival (OR 2.40; 95%CI 0.46, 12.57; P = 0.300), patient age (OR 1.06; 95%CI 1.00, 1.11; P = 0.035), and the number of positive lymph nodes (≥7; OR 0.05; 95%CI 0.07, 0.27; P < 0.001) were independent predictors of survival. CONCLUSIONS Few gastric cancers demonstrate histologic response to neoadjuvant chemotherapy. While TRG may be a valid marker for treatment response, its predictive value and clinical application in gastric cancer remains unclear. J. Surg.

Br J Cancer 2016; 114:1326-33. [PMID: 27172250 PMCID: PMC4984457 DOI: 10.1038/bjc.2016.126] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2015] [Revised: 03/11/2016] [Accepted: 04/18/2016] [Indexed: 02/07/2023] Open
Abstract
Background: We evaluated the efficacy and safety of the modified FOLFOX6 (mFOLFOX6) regimen as
a neoadjuvant chemotherapy in gastric cancer patients. Methods: Seventy-three patients with T2–T4 or N+ were enroled. Preoperative
chemotherapy consisted of three cycles of mFOLFOX6. The primary end points were
the response rate and the R0 resection rate. Prognostic factors for overall
survival (OS) were investigated using univariate and multivariate analyses. Results: Sixty-seven (91.8%) patients completed 3 cycles, with grade 3–4
toxicity arising in 33.0%. The radiology response rate was 45.8%.
Sixty-seven (91.8%) patients receiving radical surgery showed different
levels of histological regression of the primary tumour, with a ⩾50%
regression rate of 49.2%. ypTNM stage (HR 4.045, 95% CI
1.429–11.446) and tumours of diffuse and mixed type (HR 9.963, 95% CI
1.937–51.235; HR 8.890, 95% CI 1.157–68.323, respectively) were
significantly associated with OS. The pathologic regression rate (GHR;
⩾2/3/<2/3, ⩾50%/<50%) was
statistically significantly associated with OS according to a univariate
analysis. Conclusions: Perioperative mFOLFOX6 was a tolerable and effective regimen for gastric cancer.
The ypTNM stage was an independent predictor of survival. GHR
⩾50%/<50% could be used as a surrogate marker for
selecting a postoperative chemotherapy regimen.

Abstract
Gastric and esophagogastric junction cancers are heterogeneous and aggressive tumors with an unpredictable response to cytotoxic treatment. New methods allowing for the analysis of drug resistance are needed. Here, we describe a novel technique by which human tumor specimens can be cultured ex vivo, preserving parts of the natural cancer microenvironment. Using a tissue chopper, fresh surgical tissue samples were cut in 400 μm slices and cultivated in 6-well plates for up to 6 days. The slices were processed for routine histopathology and immunohistochemistry. Cytokeratin stains (CK8, AE1/3) were applied for determining tumor cellularity, Ki-67 for proliferation, and cleaved caspase-3 staining for apoptosis. The slices were analyzed under naive conditions and following 2-4 days in vitro exposure to 5-FU and cisplatin. The slice culture technology allowed for a good preservation of tissue morphology and tumor cell integrity during the culture period. After chemotherapy exposure, a loss of tumor cellularity and an increase in apoptosis were observed. Drug sensitivity of the tumors could be assessed. Organotypic slice cultures of gastric and esophagogastric junction cancers were successfully established. Cytotoxic drug effects could be monitored. They may be used to examine mechanisms of drug resistance in human tissue and may provide a unique and powerful ex vivo platform for the prediction of treatment response.

Pilot Feasibility Stud 2016; 2:18. [PMID: 27965838 PMCID: PMC5153833 DOI: 10.1186/s40814-016-0059-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2015] [Accepted: 03/08/2016] [Indexed: 12/22/2022] Open
Abstract
Background Neoadjuvant chemotherapy is a standard of care for patients with adenocarcinoma of the esophagus and stomach in Europe, but still only 20–40 % respond to therapy and the critical issue; how to treat nonresponding patients is still unclear. So far, there is no randomized trial evaluating the impact of early termination of neoadjuvant chemotherapy and immediate tumor resection in nonresponding patients with locally advanced gastroesophageal cancer on postoperative outcome. With this exploratory pilot trial, we want to get first estimates about the effect of discontinuation of chemotherapy with the aim to plan and conduct a further definitive trial. Methods/design OPTITREAT is designed as a single-center, randomized controlled pilot trial with two parallel study groups. Four weeks after starting neoadjuvant chemotherapy in all patients, clinical response will be assessed by endoscopy and endosonographic ultrasound. Then, nonresponding patients (n = 84) will be randomized in a 1:1 ratio to intervention group with stopping chemotherapy and immediate tumor resection or control group with completion of chemotherapy before surgery. Outcome measures are overall survival, R0 resection rate, perioperative morbidity and mortality, histopathological response, and quality of life. Statistical analysis will be based on the intention-to-treat population. Due to the study design as an explorative pilot trial, no formal sample size calculation was performed. The planned total sample size of 120 patients is considered ethical and large enough to show the feasibility and safety of the concept. First data on differences between the study groups in the defined endpoints will also be generated. Discussion Individualized therapy is of utmost interest in the treatment of locally advanced gastroesophageal adenocarcinoma as less than half of the patients show objective response to current chemotherapy regimens. The findings of the OPTITREAT trial will help to get first data about clinical response evaluation followed by immediate tumor resection in nonresponding patients after 4 weeks of neoadjuvant chemotherapy. Based on the results of this pilot study, a future confirmatory trial will be planned to prove efficacy and evaluate significance.

Abstract
BACKGROUND Signet ring cell carcinoma occurs as a histological variant of oesophageal adenocarcinoma. AIM In a cross-sectional study, to pursue the hypothesis that oesophageal signet ring cell cancers constitute a complication of gastro-oesophageal reflux disease. METHODS In a large national database of histopathology records, we accumulated 91 802 patients with Barrett's oesophagus (BE), 2817 with oesophageal nonsignet ring adenocarcinoma (EAC) and 278 with oesophageal signet ring cell carcinoma (SRC). The three groups were compared with respect to their clinical and demographic characteristics, as well as socio-economic risk factors (associated with patients' place of residence). RESULTS About 9% of all oesophageal adenocarcinomas harboured features of signet ring cell carcinoma. Patients with oesophageal adenocarcinoma and signet ring cell carcinoma were characterised by almost identical epidemiological patterns. Patients with either cancer type were slightly older than those with Barrett's oesophagus (EAC 68.0, SRC 66.7 vs. BE 63.7 years), and both showed a striking male predominance (EAC and SRC 85% vs. BE 67%). Both cancer types were associated with a similar set of alarm symptoms, such as dysphagia, pain and weight loss. The distribution by race (Whites vs. Blacks) and socio-economic parameters, such as levels of college education and family income, were similar among the three groups of patients. CONCLUSIONS Signet ring cell carcinoma is a rare variant of oesophageal adenocarcinoma with similar epidemiological characteristics. The reasons why a minority of reflux patients progress to develop signet ring cell carcinoma, rather than the usual type of oesophageal adenocarcinoma, remain unknown.

Abstract
INTRODUCTION In the past, elderly patients with upper GI cancers were excluded from surgery or multimodal treatment only due to their advanced age. In an aging society this way of patient selection seems to be questionable. The aim of this retrospective exploratory study was to investigate how patients with upper GI cancer over the age of 70 years differ from younger patients in the postoperative course and which parameters influence overall survival in older patient populations. PATIENTS AND METHODS From 2002 to 2012 1,005 patients underwent resection of esophageal or gastric cancer at the University of Heidelberg. 272 patients were older than 70 years and analyzed in subgroups (70-74 years: n = 146; 75-79 years: n = 82; 80 years or older: n = 44). Patients older than 70 years were compared to patients under 70 years (n = 733) with focus on differences in patients characteristics and outcome. Statistical analyses were made retrospectively on a prospective database. RESULTS Fewer older patients were treated neoadjuvantly (< 70 years: 41.5%; > 70 years: 24.7%, P < 0.001) and extended resection (abdominothoracic approach) was applied less frequently compared to patients under 70 years (< 70 years: 38.9%; > 70 years: 19.9%, P < 0.001). The pNM-category (HR 1.41/2.56) and R-status (HR 1.78) remain the most important predictive factor for survival (all < 0.001). Female patients had a longer survival than men over the age of 70 (84.9 vs. 23.5 months, P < 0.01). Patients over 80 years had a significant shortened overall survival (> 80 years: 16.7 vs. < 70 years: 37.4 months) compared to the other subgroups (P < 0.001) and a significant increased in-hospital mortality (> 80 years: 20.5% vs. < 70 years: 6.0%, P = 0.002). CONCLUSIONS An exclusion from surgical therapy due to advanced age in general seems not to be justified. However, the decision for a surgical resection in patients over 80 years should be made with caution. pNM-categories and R0-resection remain the most important predictive factors for overall survival in all subgroups. No survival benefit for neoadjuvant treatment in patients over 70 years was found, while women survived longer than men. However, the decision concerning a (radio) chemotherapy should be made individually in each patient.

Dysphagia is not a Valuable Indicator of Tumor Response after Preoperative Chemotherapy for R0 Resected Patients with Adenocarcinoma of the Gastroesophageal Junction. Scand J Surg 2015; 105:97-103. [DOI: 10.1177/1457496915594716] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2014] [Accepted: 06/11/2015] [Indexed: 01/06/2023]
Abstract
Background: Monitoring treatment response to preoperative chemotherapy is of utmost importance to avoid treatment toxicity, especially in non-responding patients. Currently, no reliable methods exist for tumor response assessment after preoperative chemotherapy. Therefore, the aim of this study was to evaluate dysphagia as a predictor of tumor response after preoperative chemotherapy and as a predictor of recurrence and survival. Methods: Patients with adenocarcinoma of the gastroesophageal junction, treated between 2010 and 2012, were retrospectively reviewed. Dysphagia scores (Mellow-Pinkas) were obtained before and after three cycles of perioperative chemotherapy together with clinicopathological patient characteristics. A clinical response was defined as improvement of dysphagia by at least 1 score from the baseline. The tumor response was defined as down staging of T-stage from initial computer tomography (CT) scan (cT-stage) to pathologic staging of surgical specimen (pT-stage). Patients were followed until death or censored on June 27th, 2014. Results: Of the 110 included patients, 59.1% had improvement of dysphagia after three cycles of perioperative chemotherapy, and 31.8% had a chemotherapy-induced tumor response after radical resection of tumor. Improvement of dysphagia was not correlated with the tumor response in the multivariate analysis (p = 0.23). Moreover, the presence of dysphagia was not correlated with recurrence (p = 0.92) or survival (p = 0.94) in the multivariate analysis. Conclusion: In our study, improvement of dysphagia was not valid for tumor response evaluation after preoperative chemotherapy and was not correlated with the tumor response. The presence of dysphagia does not seem to be a predictor of recurrence or survival.

Abstract
Some studies have shown the usability of neoadjuvant chemotherapy (NAC) in gastric cancer (GC). Nevertheless there are a few predictive markers of the effectiveness of NAC in GC. The aim of this study is to assess the predictive impact of organic cation transporter 2 (OCT2) expression on response to neoadjuvant chemotherapy (NAC) in gastric cancer. We retrospectively assessed 66 patients with advanced gastric cancer received NAC with S-1/cisplatin or paclitaxel/cisplatin. Expression levels of OCT2 were assessed by immunohistochemistry in pre-chemotherapy biopsies and correlated with clinicopathologic parameters including pathologic response. High expression level of OCT2 (OCT2(high)) was significantly associated with intestinal type according to Laurén classification (P = 0.03) and low histologic grade (P = 0.03). In univariate analysis of the entire cohort, no variables showed any significant association with a response, although intestinal type (P = 0.09), low histologic grade (P = 0.09), and OCT2(high) (P = 0.07) tended to be more frequent in responders compared with non-responders. When the two treatment groups were separately assessed in the univariate analysis, a significantly higher rate of OCT2(high) was observed in responders compared with non-responders in the S-1/cisplatin group (P = 0.001). In addition, multivariate analysis identified OCT2(high) as the sole independent predictor of response (P = 0.04). However, in the paclitaxel/cisplatin group, no variables were associated with response. Taken together, our results suggest that OCT2(high) may represent a potential predictor of response to NAC with S-1/cisplatin in gastric cancer.

Abstract
Neoadjuvant platin-based therapy is accepted as a standard therapy for advanced esophageal adenocarcinoma (EAC). Patients who respond have a better survival prognosis, but still a significant number of responder patients die from tumor recurrence. Molecular markers for prognosis in neoadjuvantly treated EAC patients have not been identified yet. We investigated the epidermal growth factor receptor (EGFR) in prognosis and chemotherapy resistance in these patients. Two EAC patient cohorts, either treated by neoadjuvant cisplatin-based chemotherapy followed by surgery (n=86) or by surgical resection (n=46) were analyzed for EGFR protein expression and gene copy number. Data were correlated with clinical and histopathological response, disease-free and overall survival. In case of EGFR overexpression, the prognosis for neoadjuvant chemotherapy responders was poor as in non-responders. Responders had a significantly better disease-free survival than non-responders only if EGFR expression level (p=0.0152) or copy number (p=0.0050) was low. Comparing neoadjuvantly treated patients and primary resection patients, tumors of non-responder patients more frequently exhibited EGFR overexpression, providing evidence that EGFR is a factor for indicating chemotherapy resistance. EGFR overexpression and gene copy number are independent adverse prognostic factors for neoadjuvant chemotherapy-treated EAC patients, particularly for responders. Furthermore, EGFR overexpression is involved in resistance to cisplatin-based neoadjuvant chemotherapy.

Abstract
OBJECTIVE Adenocarcinomas at the gastro-oesophageal junction (GOJ) are currently stratified by tumour location. This retrospective study examines the association of preneoplastic conditions and inflammation of the gastric mucosa with GOJ cancer at different locations and compares them with nonjunctional gastric cancers. PATIENTS AND METHODS A total of 520 patients with junctional and nonjunctional gastric cancer were assessed for the presence and degree of intestinal metaplasia, glandular atrophy and inflammation in the stomach. Histopathological data were complete for 428 patients (68.9% men, median age 67.7 years), including 172 patients with GOJ cancer (GOJ1: 1-5 cm proximal to the junction, GOJ2: 'true' junctional, GOJ3: 2-5 cm distal to the junction). Gastric inflammation and preneoplastic conditions were scored according to the updated Sydney classification and further stratified into respective operative link on gastritis assessment (OLGA) and operative link on gastritis assessment on intestinal metaplasia (OLGIM) stages. RESULTS The prevalence and degree of gastric atrophy and intestinal metaplasia were significantly lower in GOJ1 than GOJ3 (P<0.01). Preneoplastic conditions in the stomach were similar in GOJ3 compared with nonjunctional gastric cancer. GOJ1 were almost exclusively (98.4%) of the intestinal type, whereas GOJ2 and GOJ3 were the diffuse type in 22.6 and 22.4% of the patients (P<0.001). Of all patients, only 8.5 and 12.7% presented with stage III/IV according to OLGA and OLGIM, respectively. However, data for OLGA and OLGIM staging were only available in 61.2 and 67.9% of patients, respectively. CONCLUSION GOJ1 are less likely to be associated with gastric pathology compared with GOJ3 or nonjunctional gastric cancer. OLGA or OLGIM staging in patients with advanced gastro-oesophageal cancer seems to be of limited value.

Abstract
OBJECTIVE Intrathoracic anastomotic leakage after intended curative resection for cancer in the esophagus or gastroesophageal junction has a negative impact on long-term survival. The aim of this study was to investigate whether an anastomotic leakage was associated with an increased recurrence rate. METHODS This nationwide study included consecutively collected data on patients undergoing curative surgical resection with intrathoracic anastomosis, alive 8 weeks postoperatively, between 2003 and 2011. Patients with incomplete resection, or metastatic disease intraoperatively, were excluded. Only biopsy-proven recurrences were accepted. RESULTS In total, 1085 patients were included. The frequency of anastomotic leakage was 8.6%. The median follow-up time was 29 months (interquartile range [IQR]: 13-58 months). Overall, 369 (34%) patients had disease recurrence, of which 346 patients died of recurrent gastroesophageal carcinoma. Twenty-three patients were alive with recurrence at the censoring date. In the study period, 333 patients died without signs of recurrent disease. The overall median time to recurrence was 66 weeks (IQR: 38-109 weeks). Distant metastases were found in 267 (25%), and local disease recurrence in 102 (9%) patients. Overall, 5-year disease-free survival in patients with leakage was 27%, versus 39% in those without leakage (P = .017). Anastomotic leakage was independently associated with higher risk of recurrence (hazard ratio [HR] = 1.63; 95% confidence interval [CI]: 1.17-2.29, P = .004) and all-cause mortality (HR = 1.57; 95% CI: 1.23-2.05, P < .0001). CONCLUSIONS Intrathoracic anastomotic leakage increased the risk of recurrence in patients who underwent curative gastroesophageal cancer resection.

Abstract
BACKGROUND Perioperative chemotherapy with epirubicin, cisplatin and 5-fluorouracil (5-FU) (ECF)-like regimens is the European standard for patients with adenocarcinoma of the gastroesophageal junction (GEJ) or gastric body (GaCa) stage UICC II/III (staged according to the Union for International Cancer Control). However, limited data exist on the histopathological response and relevance of prognosis for patients homogeneously treated with ECF(-like) therapies. METHODS All patients with GEJ/GaCa treated from September 2004 to September 2008 by perioperative ECF(-like) chemotherapy were retrospectively analyzed. Cisplatin and 5-FU were substituted with oxaliplatin or capecitabine when indicated. The histopathological response was assessed using the Becker score. RESULTS Seventy-seven patients were analyzed with a median follow-up of 72.3 months. R0 resection was achieved in 53 of 68 operated patients. Recurrence was observed in 25 (32.5%) of these curatively treated patients, whereas 53/77 patients (68.8%) died, 39 (50.6%) of whom tumor related. The 5-year overall survival (OS) for the intention-to-treat population was 36.3%, and the 5-year tumor-specific survival was 42.2%. Pathological complete response (pCR) was seen in 10 patients (13.0%) and near pCR in 3 patients (3.9%). Patients with pCR had a significantly prolonged 5-year OS of 80.0 versus 29.7% compared to the nonhistopathological complete remission group (p = 0.01). CONCLUSION In our retrospective analysis, ECF(-like) pretreatment resulted in a (near) pCR rate of 16.9%. In line with other regimens, our data suggest that histopathological response predicts the OS in patients treated with ECF(-like) regimens.

Abstract
BACKGROUND Salvage surgery as an additional therapy option is currently discussed for an increasing number of patients with esophageal cancer after definitive radio(chemo)therapy after tumor progression, recurrence or on explicit request of the patient. OBJECTIVES The objective of this study was an analysis of the surgical option of salvage esophagectomy after definitive radiation in patients with esophageal cancer. Additionally the current literature on this topic was evaluated. MATERIAL AND METHODS A total of 92 patients with esophageal cancer from a prospective database were included in this study who underwent esophagectomy either after neoadjuvant radio(chemo)therapy (< 50 Gy) or definitive radio(chemo)therapy (> 50 Gy) between 2002 and 2012. The analysis was performed retrospectively. RESULTS The median survival of the two groups of patients was not significantly different after initial diagnosis with 24.2 months (95 % CI 0.0-51.93) for patients undergoing definitive radio(chemo)therapy and 30.7 months (95 % CI 9.3-52.2) for patients after neoadjuvant therapy (p = 0.96). Both patient groups showed no differences in pretherapeutic characteristics and response to radio(chemo)therapy. Postoperative complications and perioperative mortality were not different. DISCUSSION Salvage esophagectomy is now an additional treatment option after definitive radio(chemo)therapy in patients with esophageal cancer. In preselected patients with tumor recurrence, progression or with a strong wish for surgical therapy, salvage surgery should be discussed in interdisciplinary tumor boards after exclusion of distant metastases.

Assessment of tumor regression of esophageal adenocarcinomas after neoadjuvant chemotherapy: comparison of 2 commonly used scoring approaches. Am J Surg Pathol 2014; 38:1551-6.

Abstract
Histopathologic determination of tumor regression provides important prognostic information for locally advanced gastroesophageal carcinomas after neoadjuvant treatment. Regression grading systems mostly refer to the amount of therapy-induced fibrosis in relation to residual tumor or the estimated percentage of residual tumor in relation to the former tumor site. Although these methods are generally accepted, currently there is no common standard for reporting tumor regression in gastroesophageal cancers. We compared the application of these 2 major principles for assessment of tumor regression: hematoxylin and eosin-stained slides from 89 resection specimens of esophageal adenocarcinomas following neoadjuvant chemotherapy were independently reviewed by 3 pathologists from different institutions. Tumor regression was determined by the 5-tiered Mandard system (fibrosis/tumor relation) and the 4-tiered Becker system (residual tumor in %). Interobserver agreement for the Becker system showed better weighted κ values compared with the Mandard system (0.78 vs. 0.62). Evaluation of the whole embedded tumor site showed improved results (Becker: 0.83; Mandard: 0.73) as compared with only 1 representative slide (Becker: 0.68; Mandard: 0.71). Modification into simplified 3-tiered systems showed comparable interobserver agreement but better prognostic stratification for both systems (log rank Becker: P=0.015; Mandard P=0.03), with independent prognostic impact for overall survival (modified Becker: P=0.011, hazard ratio=3.07; modified Mandard: P=0.023, hazard ratio=2.72). In conclusion, both systems provide substantial to excellent interobserver agreement for estimation of tumor regression after neoadjuvant chemotherapy in esophageal adenocarcinomas. A simple 3-tiered system with the estimation of residual tumor in % (complete regression/1% to 50% residual tumor/>50% residual tumor) maintains the highest reproducibility and prognostic value.

Abstract
Perioperative or preoperative radiochemotherapy (RCTx) is nowadays standard for locally advanced esophageal cancer in Europe, as randomized studies have shown a significant survival benefit for patients with multimodal treatment. As responders and nonresponders have a significantly different prognosis, a response-based tailored preoperative treatment would be of utmost interest. An established method is a metabolic response evaluation by 18F-fluorodeoxyglucose positron emission tomography (FDG-PET). The level of metabolic response is known to be dependent on the localization, tumor entity and type of preoperative treatment. Association of FDG-PET with later response and prognosis was shown for absolute standardized uptake values (SUV) or a decrease of SUV levels before and after therapy but there are also contradictory findings in the literature and no prospective validation. However, neither time points nor cut-off for metabolic response evaluation have been defined so far. The most interesting approach seems to be early response monitoring during preoperative chemotherapy, which has shown promising results in prospective single center trials (MUNICON I/II) during chemotherapy of adenocarcinoma of the esophagogastric junction (AEG), but needs to be validated in prospective multicenter trails.
