Leptomeningeal carcinomatosis and brain metastases in gastroesophageal carcinoma: a real-world analysis of clinical and pathologic characteristics and outcomes. J Neurooncol 2024; 167:111-122. [PMID: 38372902 PMCID: PMC10978709 DOI: 10.1007/s11060-024-04576-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Accepted: 01/16/2024] [Indexed: 02/20/2024]
Abstract
BACKGROUND Brain metastasis (BrM) and Leptomeningeal Carcinomatosis (LMC) are uncommon complications in gastroesophageal carcinoma (GEC) patients. These patients have a poor prognosis and are challenging to treat. We described the clinicopathologic features and outcomes in the largest cohort of Central Nervous System (CNS) metastasis in GEC patients. METHODS single-center retrospective study of GEC treated from 2007 to 2021. Clinicopathologic characteristics and treatment modalities were reviewed. Survival was calculated from the date of CNS diagnosis until date of death/last follow-up using the Kaplan-Meier method. A multivariable Cox proportional hazards regression model was used. RESULTS Of 3283 GEC patients, 100 (3.04%) were diagnosed with BrM and 20 with LMC (0.61%). Patients with known human epidermal growth factor receptor 2 (HER2) status (N = 48), 60% were HER2 positive (defined as IHC 3 + or IHC 2+/FISH+). Among LMC patients most were signet-ring subtype (85%), and only 15% (2/13) were HER2 positive. Median survival was 0.7; 3.8; and 7.7 months in BrM patients treated with best supportive care, radiation, and surgery, respectively (p < 0.001). In LMC, median survival was 0.7 month in patients who had best supportive care (7/19) and 2.8 months for those who had whole brain radiation therapy (p = 0.015). Multivariate analysis showed worse outcomes in ECOG ≥ 2 (p = 0.002), number of BrM ≥ 4 (p < 0.001) and number of metastatic sites (p = 0.009). CONCLUSION HER2 expression were enriched in patients with BrM, while it is uncommon in LMC. Patients treated with surgery followed by radiation had an improved OS in BrM and WBRT benefited patients with LMC.

Pang T, Nie M, Yin K. The correlation between the margin of resection and prognosis in esophagogastric junction adenocarcinoma. World J Surg Oncol 2023; 21:316. [PMID: 37814242 PMCID: PMC10561513 DOI: 10.1186/s12957-023-03202-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 09/30/2023] [Indexed: 10/11/2023] Open
Abstract
Adenocarcinoma of the gastroesophageal junction (AEG) has become increasingly common in Western and Asian populations. Surgical resection is the mainstay of treatment for AEG; however, determining the distance from the upper edge of the tumor to the esophageal margin (PM) is essential for accurate prognosis. Despite the relevance of these studies, most have been retrospective and vary widely in their conclusions. The PM is now widely accepted to have an impact on patient outcomes but can be masked by TNM at later stages. Extended PM is associated with improved outcomes, but the optimal PM is uncertain. Academics continue to debate the surgical route, extent of lymphadenectomy, preoperative tumor size assessment, intraoperative cryosection, neoadjuvant therapy, and other aspects to further ensure a negative margin in patients with gastroesophageal adenocarcinoma. This review summarizes and evaluates the findings from these studies and suggests that the choice of approach for patients with adenocarcinoma of the esophagogastric junction should take into account the extent of esophagectomy and lymphadenectomy. Although several guidelines and reviews recommend the routine use of intraoperative cryosections to evaluate surgical margins, its generalizability is limited. Furthermore, neoadjuvant chemotherapy and radiotherapy are more likely to increase the R0 resection rate. In particular, intraoperative cryosections and neoadjuvant chemoradiotherapy were found to be more effective for achieving negative resection margins in signet ring cell carcinoma.

Abstract
OBJECTIVE Clinical predictors of pathological complete response have not reliably identified patients for whom an organ-sparing approach following neoadjuvant chemoradiation be undertaken for esophageal cancer patients. We sought to identify high-risk predictors of residual carcinoma that may preclude patients from a selective surgical approach. BACKGROUND Patients treated with neoadjuvant chemoradiation followed by esophagectomy for esophageal adenocarcinoma were identified. PATIENTS AND METHODS Correlation between clinical and pathologic complete responses were examined. Regression models and recursive partitioning were utilized to identify features associated with residual carcinoma. External validation of these high-risk factors was performed on a data set from an independent institution. RESULTS A total of 326 patients were identified, in whom clinical complete response was noted in 104/326 (32%). Pathologic complete response was noted in only 33/104 (32%) of these clinical complete responders. Multivariable analysis identified that the presence of stricture ( P =0.011), positive biopsy ( P =0.010), and signet ring cell histology ( P =0.019) were associated with residual cancer. Recursive partitioning corroborated a 94% probability of residual disease, or greater, for each of these features. The positive predictive value was >90% for these characteristics. A SUV max >5.4 at the esophageal primary in the absence of esophagitis was also a high-risk factor for residual carcinoma. External validation confirmed these high-risk factors to be implicated in the finding of residual carcinoma. CONCLUSIONS Clinical parameters of response are poor predictors of complete pathologic response leading to challenges in selecting candidates for active surveillance. However, we characterize several high-risk features for residual carcinoma which indicate that esophagectomy should not be delayed.

Neoadjuvant chemotherapy improves survival in patients with oesophageal mucinous adenocarcinoma: Post-hoc analysis of the UK MRC OE02 and OE05 trials. Eur J Cancer 2022; 170:140-148.

Abstract
BACKGROUND Adenocarcinoma with more than 50% extracellular mucin is a relatively rare histological subtype of gastrointestinal adenocarcinomas. The clinical impact of extracellular mucin in oesophageal adenocarcinoma (OeAC) has not been investigated in detail. We hypothesised that patients with mucinous OeAC (OeACmucin) do not benefit from neoadjuvant chemotherapy. METHODS OeAC patients either treated by surgery alone in the OE02 trial (S-patients) or by neoadjuvant chemotherapy followed by surgery (CS-patients) in OE02 or OE05 trials were included. Cancers from 1055 resection specimens (OE02 [test cohort]: 187 CS, 185 S; OE05 [validation cohort]: 683 CS) were classified as either mucinous (more than 50% of the tumour area consists of extracellular mucin, OeACmucin) or non-mucinous adenocarcinoma (OeACnon-mucin). The relationship between histological phenotype, clinicopathological characteristics, survival and treatment was analysed. RESULTS Overall, 7.3% and 9.6% OeAC were classified as OeACmucin in OE02 and OE05, respectively. In OE02, the frequency of OeACmucin was similar in S and CS-patients. Patients with OeACmucin treated with surgery alone had a poorer overall survival compared with OeACnon-mucin patients (hazard ratio: 2.222, 95% confidence interval: 1.08-4.56, P = 0.025). Patients with OeACmucin treated with neoadjuvant chemotherapy and surgery had similar survival as OeACnon-mucin patients in test and validation cohort. CONCLUSIONS This is the first study to suggest in a post-hoc analysis of material from two independent phase III clinical trials that the poor survival of patients with mucinous OeAC can be improved by neoadjuvant chemotherapy. Future studies are warranted to identify potential underlying biological, biochemical or pharmacokinetic interactions between extracellular mucin and chemotherapy.

Abstract
Gastric carcinoma is one of the most common types of cancer worldwide and a leading cause of cancer-related mortality. Gastric carcinoma is histologically subdivided into differentiated and undifferentiated carcinoma, with the latter including poorly differentiated carcinoma and signet ring cell carcinoma (SRCC). Poorly differentiated carcinoma and SRCC have a worse prognosis compared with differentiated carcinoma. Peroxisome proliferator-activated receptors (PPARs) are nuclear hormone receptors and the PPAR-α subtype regulates important cellular functions, including cell proliferation, energy metabolism, oxidative stress, immune responses and cell differentiation. The aim of the present study was to elucidate the associations between clinicopathological factors and PPAR-α expression in patients with gastric carcinoma. The immunohistochemical staining of specimens obtained from 57 patients showed that PPAR-α expression was slightly weaker in undifferentiated carcinoma than in differentiated carcinoma (P<0.01). PPAR-α expression also significantly differed between poorly differentiated carcinoma (both positive and negative: 14/20, 70%) and SRCC (not expressed: 0/7, 0%) (P<0.01). However, PPAR-α expression was not significantly affected by age, lymph node invasion, venous invasion, lymph node metastasis, depth of invasion or stage. Collectively, the present results demonstrated that the downregulated expression of PPAR-α may play a key role in the biological transformation of tumors. Therefore, PPAR-α appears to be an important protein related to histology and may hold promise as a prognostic marker. Further studies with a larger number of subjects are needed to elucidate the relationship between PPAR-α expression and tumor progression and to analyze long-term clinical survival.

Abstract
INTRODUCTION Although surgery is currently the first choice for patients with renal cell carcinoma and vena cava tumour thrombus, the surgery is difficult, with many complications, and the prognosis of patients is not ideal. Renal cell carcinoma is not sensitive to traditional radiotherapy, but the development of stereotactic ablative body radiotherapy (SABR) technology with the characteristics of high precision, dose and conformity has made the radiotherapy of renal cell carcinoma reexamined. METHODS AND ANALYSIS STUDY DESIGN: This trial is a single-arm cohort study sponsored by Peking University Third Hospital. STUDY TREATMENT Preoperative stereotactic ablative radiotherapy combined with surgical treatment. PRIMARY ENDPOINTS: (1) Adverse reactions after 4-6 weeks of SABR. (2) Mayo staging of tumour thrombus. (3) The length of the tumour thrombus from the corresponding anatomical mark. (4) Invasion of the inferior vena cava wall. (5) Recurrent-free survival rate of the tumour. (6) Cancer-specific survival rate. (7) Overall survival rate. (8) Perioperative indicators including operation time, intraoperative bleeding volume and postoperative complications. SECONDARY ENDPOINTS: (1) The longest diameter of the tumour and (2) Lymph node condition. MAIN INCLUSION CRITERIA Patients with renal cell carcinoma and inferior vena cava tumour thrombus graded from Mayo II to IV and eligible for radical nephrectomy and inferior vena cava thrombectomy. MAIN EXCLUSION CRITERIA Patients with previous targeted therapy, chemotherapy or other interventions, or who cannot tolerate SABR or surgery. PLANNED SAMPLE SIZE 20 patients. ETHICS AND DISSEMINATION The trial protocol and the informed consent of the subjects were submitted and approved by the Peking University Biomedical Ethics Committee. TRIAL REGISTRATION NUMBER ChiCTR1800015118.

Abstract
BACKGROUND The clinical significance of signet ring cells (SRCs) in surgical esophageal and esophagogastric junction adenocarcinoma (EEGJA) remains unclear now.
AIM To explore the association between the presence of SRCs and the clinicopathological and prognostic characteristics in surgical EEGJA patients by combining and analyzing relevant studies.
METHODS The PubMed, Web of Science, and EMBASE electronic databases were searched for the relevant literature up to March 28, 2021. The relative risk (RR) with 95% confidence interval (CI) was calculated to assess the relationship between SRCs and clinicopathological parameters of surgical EEGJA patients, and the hazard ratio (HR) with 95%CI was calculated to explore the impact of SRC on the prognosis. All statistical analyses were conducted with STATA 12.0 software.
RESULTS A total of ten articles were included, involving 30322 EEGJA patients. The pooled results indicated that the presence of SRCs was significantly associated with tumor location (RR: 0.76, 95%CI: 0.61-0.96, P = 0.022; I2 = 49.4%, P = 0.160) and tumor-node-metastasis stage (RR: 1.30, 95%CI: 1.02-1.65, P = 0.031; I2 = 73.1%, P = 0.002). Meanwhile, the presence of SRCs in surgical EEGJA patients predicted a poor overall survival (HR: 1.36, 95%CI: 1.12-1.65, P = 0.002; I2 = 85.7%, P < 0.001) and disease-specific survival (HR: 1.86, 95%CI: 1.55-2.25, P < 0.001; I2 = 63.1%, P = 0.043).
CONCLUSION The presence of SRCs is related with advanced tumor stage and poor prognosis and could serve as a reliable and effective parameter for the prediction of postoperative survival and formulation of therapy strategy in EEGJA patients. However, more high-quality studies are still needed to verify the above findings.

Abstract
Background Signet ring cell carcinoma (SRC) is a rare pathological subtype of mucinous adenocarcinoma (AC). Clinical features, prognosis, and especially treatment methods between SRC and AC of the esophagus remain controversial. Thus, we conducted this study to explore the differences in clinicopathological characteristics and treatment modalities between SRC and AC of the esophagus. Methods A retrospective cohort study based on the Surveillance, Epidemiology, and End Results (SEER) program database was conducted. Patients diagnosed with SRC or AC not otherwise specified (NOS) were selected between 2004 and 2018. We investigated the prognosis of SRC and AC in terms of overall survival (OS). A subgroup analysis was performed according to the stage and different treatment methods. Results A total of 24,987 patients were enrolled, including 1,147 with SRC and 23,840 with AC. In the multivariate Cox analysis of the whole cohort, SRC, tumor site, differentiation, metastases, American Joint Committee on Cancer (AJCC) 6th edition staging, treatment, tumor size, lymph nodes examined, and positive lymph nodes were independent risk factors. The results of the subgroup analysis showed that surgery alone was associated with better OS for AC at the early stage, but was not significantly different for SRC (P=0.896). Surgery plus adjuvant therapy was the best treatment for SRC and AC at the late stage. In the multivariate Cox analysis, the treatment of surgery plus adjuvant therapy had a tendency towards better OS at the early stage [hazard ratio (HR): 0.64, 95% confidence interval (CI): 0.39-1.1, P=0.08]. Conclusions SRC is an independent risk factor, with a higher grade of differentiation, later stage, larger tumor size, more positive lymph nodes, and poorer prognosis compared with AC. Surgery plus adjuvant therapy seems to be useful for SRC at the early stage, but further research is needed.

Abstract
BACKGROUND While the prognosis of patients with locoregional esophageal adenocarcinoma (EAC) has improved in the neoadjuvant treatment (NAT) era, high-grade histology (G3) is still associated with a limited treatment response. We sought to investigate oncologic outcomes in patients after esophagectomy for G3 EAC and to identify predictors of poor survival among these patients. METHODS Patients with EAC who underwent resection with curative intent in 2011-2018 were divided by histologic grade (G3, G1/2) and compared for overall survival (OS). Cox regression was performed to analyze the response to NAT and the predictive role of signet ring cell (SRC) features. RESULTS The cohort included 163 patients, 94 (57.7%) with G3 histology. NAT was administered to 69 (73.4%) patients. Following resection, OS in the G3 EAC group was 30 months (95% confidence interval [CI] 23.9-36.1). On univariate analysis, G3 disease (p = 0.050) and SRC features (p = 0.019) predicted low OS. Median survival in the G3 EAC group was worse in patients with SRC histology (18 months, 95% CI 8.6-27.4) than those without (30 months, 95% CI 23.8-36.1; p = 0.041). No patients with SRC histology were alive at 5 years of follow-up. Among all patients administered NAT, 88.2% of those with SRC showed minimal or no pathologic response and only 27.8% were downstaged. CONCLUSIONS High-grade histology was found in most patients with EAC and predicted poor survival and treatment response. SRC features in patients with G3 disease were associated with lower OS. The benefit of NAT for G3 EAC in patients with SRC histology appears limited.

Preoperatively Treated Diffuse-Type Gastric Adenocarcinoma: Glucose vs. Other Energy Sources Substantially Influence Prognosis and Therapy Response. Cancers (Basel) 2021; 13:cancers13030420.

Abstract
Simple Summary The diffuse type of gastric adenocarcinoma (dGAC) generally confers a poor prognosis compared to intestinal type. Some dGACs are not avid on fluorine-18 fluoro-2-deoxy-D-glucose PET (FDG-PET) while others seem to consume glucose avidly. We analyzed the outcomes based on the avidity of the primary on baseline FDG-PET. Our data suggest that if dGACs used glucose as an energy source then the prognosis was very poor while non-glucose sources improved prognosis. Multi-platform (including metabolomics) profiling of dGACs would yield useful biologic understanding. Abstract Diffuse type of gastric adenocarcinoma (dGAC) generally confers a poor prognosis compared to intestinal type. Some dGACs are not avid on fluorine-18 fluoro-2-deoxy-D-glucose PET (FDG-PET) while others seem to consume glucose avidly. We analyzed the outcomes based on the avidity (high with standardized uptake value (SUV) > 3.5 or low with SUV ≤ 3.5) of the primary on baseline FDG-PET. We retrospectively selected 111 localized dGAC patients who had baseline FDG-PET (all were treated with preoperative chemotherapy and chemoradiation). FDG-PET avidity was compared with overall survival (OS) and response to therapy. The mean age was 59.4 years and with many females (47.7%). The high-SUV group (58 (52.3%) patients) and the low-SUV group (53 (47.7%) patients) were equally divided. While the median OS for all patients was 49.5 months (95% CI: 38.5–98.8 months), it was 98.0 months (95% CI: 49.5–NE months) for the low-SUV group and 36.0 months for the high-SUV (p = 0.003). While the median DFS for all patients was 38.2 months (95% CI: 27.7–97.6 months), it was 98.0 (95% CI: 36.9–NE months) months for the low-SUV group was and only 27.0 months (95% CI: 15.2–63.2 months) for the high-SUV group (p = 0.005). Clinical responses before surgery were more common in the low-SUV group but overall we observed only 4 pathologic complete responses in 111 patients. Our unique data suggest that if dGACs used glucose as an energy source then the prognosis was very poor while non-glucose sources improved prognosis. Multi-platform (including metabolomics) profiling of dGACs would yield useful biologic understanding.

Abstract
Diffuse gastric cancer (DGC) is a distinct histopathologic and molecular disease, characterized by mutations in CDH1, RHOA, and others. In addition, DGC is associated with familial syndromes, including hereditary DGC and germline mutation in CDH1. Clinically, this subtype of gastric adenocarcinoma is associated with a poor prognosis and possible resistance to available systemic therapies. An understanding of the genetic and molecular underpinnings of DGC may help inform of its clinical behavior and aid in screening, diagnosis, and response to treatment. In this review, we will review the current histologic, molecular, and genetic landscape of DGC and its relevance to clinical practice.

Abstract
Esophageal carcinoma comprises two major subtypes-squamous cell carcinoma and adenocarcinoma, the incidences of which vary widely across the world and also depend on the location within the esophagus. The staging of esophageal cancer (EC) also remains unique among various gastrointestinal carcinomas, as it takes into account the location, histologic type, and grade. Its management has been evolving over the years and the recent American Joint Committee on Cancer staging system has been updated to reflect the changing practice and new data. It is clear that preoperative neoadjuvant therapy is increasingly being used for the treatment of locally advanced esophageal carcinomas, followed by surgical resection that improves survival. A variety of histologic changes can be seen after neoadjuvant therapy, which can be challenging for the pathologists. The presence of residual tumor in the surgically resected specimen and lymph node following neoadjuvant therapy is associated with poor prognosis. Hence, a thorough pathologic assessment of tumor regression grade and accurate tumor staging is required by pathologists to provide valuable prognostic information to guide further management. Tumor regression grading in ECs needs to be improved and standardized.

Abstract
BACKGROUND Multiple investigations have shown inferior outcomes for esophageal cancer patients with signet ring cell (SRC) histology. Traditionally, SRC adenocarcinoma has been defined by ≥50% of the tumor composed of SRC. We hypothesized that patients with SRC even <50% would show resistance to standard multimodality therapy with poorer long-term outcomes. METHODS Patients treated with trimodality therapy for adenocarcinoma from 2006 to 2018 were evaluated for SRC on pretreatment biopsy specimens. Available hematoxylin and eosin slides containing SRC tumors were re-reviewed by an esophageal pathologist to quantify the percent composition of SRC. RESULTS SRC histology was identified on at least 1 pathologic specimen in 106 of 819 (13%) patients. Rates of pathologic complete response (pCR) among usual-type and SRC tumors were 25% (177/713) and 10% (11/106), respectively (P = .006). The pretreatment SRC components did not independently affect the rate of pCR (1%-10% SRC: 4% [2/46] pCR; 11%-49% SRC: 25% [7/28] pCR; 50%-100% SRC: 7% [2/30] pCR). Kaplan-Meier analysis demonstrated worse survival among patients with any degree of SRC present on pretreatment biopsy, as compared with usual-type esophageal adenocarcinoma (P < .0001). Cox multivariable analysis failed to identify a relationship between increasing SRC component and poorer survival. CONCLUSIONS We present the only known evaluation of the percentage of SRC component in esophageal carcinoma. Our data support the hypothesis that esophageal adenocarcinoma with any component of SRC are more resistant to chemoradiation with poorer survival. Pathologic reporting of esophageal adenocarcinoma should include any component of SRC. Alternative therapies in patients with any SRC component may be indicated.

Ann Thorac Surg 2020; 111:214-222. [PMID: 32579884 DOI: 10.1016/j.athoracsur.2020.04.134] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2019] [Revised: 03/21/2020] [Accepted: 04/27/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND Signet ring cell (SRC) histology is regarded as a poor prognostic indicator for esophageal cancer. The objectives of this study were to understand the clinical presentation and stage-specific survival outcomes of patients with SRC and nonsignet adenocarcinoma (AC). METHODS From 2004 to 2016, 140,324 patients were diagnosed with esophageal and gastroesophageal junction cancers in the National Cancer Database. Demographics, tumor variables, and treatment were studied. Overall survival was shown by the Kaplan-Meier method, and random survival forest identified important predictors. RESULTS SRC patients (N = 3825) comprised roughly 3% of esophageal cancers per year. SRC patients were less likely to present at early stage disease (cStage I: 10.2% vs 17.8% for AC; P < .001) and more likely to have pathologic upstaging (28% vs 16%, P < .001) and less pathologic downstaging after neoadjuvant therapy (36% vs 48%, P < .001). More SRC patients had positive margins after resection (15% vs 6.0%, P < .001). In a stage-matched comparison median survival for SRC patients was worse than for AC patients (cStage I: 60 vs 113 months; cStage II: 31 vs 40 months; cStage III: 22 vs 30 months). Clinical tumor and nodal stage, chemotherapy sequence, and age were important predictors of survival. CONCLUSIONS SRC patients had worse survival than their AC counterparts. Worse biology and higher rates of incomplete resection in SRC should steer patients away from undergoing limited resection, such as endoscopic submucosal dissection, even when identified at very early stages. In future esophageal cancer staging iterations, separating SRC from AC appears to be indicated because of their different clinical behavior and response to therapy.

Abstract
The objective of this study was to test the hypothesis that mucin-producing adenocarcinoma (MA) exhibits a more advanced clinical presentation and worse prognosis than conventional adeno-carcinoma (CA) in patients undergoing esophagectomy. Patient demographic and clinical variables and cancer-specific survival were collected from the U.S. Surveillance Epidemiology and End Results database between 1988 and 2006. Esophagectomy was performed for 105 patients with MA and 5473 patients with CA. The MA cohort exhibited a similar age at presentation, gender, and anatomic location (lower third of the esophagus/abdominal) as the CA cohort. We found trends toward advanced pathologic stage of disease of MA compared with CA (Stage IIB to IV 56 vs 46%), higher grade tumors (Grade III/IV, 44 vs 34%), positive lymph nodes (51 vs 40%), and poorer mean survival. For both groups, after multivariate analysis, age at diagnosis, tumor stage, and grade were negative predictors of survival (hazard ratios 1.02, 1.39, and 1.32, respectively; P < 0.001). Although this study suggests that patients with resected MA of the esophagus have a trend toward worse clinical presentation and survival than patients with resected CA, the observations are not significant and do not support our hypothesis or results from single-institution studies.

Abstract
Peritoneal surface oncology has emerged as a subspecialty of surgical oncology, with the growing popularity of surgical treatment of peritoneal metastases comprising of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Pathological evaluation plays a key role in multidisciplinary management but there are still many areas where there are no guidelines or consensus on reporting. Some tumors presenting to a peritoneal surface oncology unit are rare and pathologists my not be familiar with diagnosing and classifying those. In this manuscript, we have reviewed the evidence regarding various aspects of histopathological evaluation of peritoneal tumors. It includes establishing a diagnosis, appropriate classification and staging of common and rare tumors and evaluation of pathological response to chemotherapy. In many instances, the information captured is of prognostic value alone with no direct therapeutic implications. But proper capturing of such information is vital for generating evidence that will guide future treatment trends and research. There are no guidelines/data set for reporting cytoreductive surgery specimens. Based on the authors' experience, a format for handling/grossing and synoptic reporting of these specimens is provided.

Abstract
BACKGROUND Signet ring cell adenocarcinoma (SRC) is a less common histologic variant of esophageal adenocarcinoma (ACA). The low frequency of SRC limits the ability to make data-driven clinical recommendations for these patients. METHODS The National Cancer Database was queried for adult patients with clinical stage I, II, or III adenocarcinoma of the noncervical esophagus diagnosed between 2004 and 2015 and stratified by SRC versus all other ACA variants. Cox proportional hazard regression models were adjusted for patient, tumor, and treatment characteristics. The role of surgery in SRC was evaluated among patients treated with chemoradiation alone versus chemoradiation with esophagectomy. RESULTS Of the 681 SRC and 13,543 ACA patients who underwent esophagectomy, no significant differences in age, sex, race, or comorbidities were identified. Patients with SRC were more likely to have high-grade tumors (84% vs 41%, P < .001) and stage III tumors (47% vs 39%, P < .001) compared with patients with ACA. Complete (R0) resection was less common in SRC (81% vs 90%, P < .001). Adjusted 5-year mortality risk from surgery was higher for SRC patients compared with ACA patients (hazard ratio, 1.242; 95% confidence interval, 1.126-1.369; P < .001). Among SRC tumors, chemoradiation with esophagectomy was associated with superior survival (hazard ratio, 0.429; 95% confidence interval, 0.339-0.546; P < .001) compared with chemoradiation alone. CONCLUSIONS Among surgically managed patients SRC appears to have a worse prognosis than ACA, which may reflect the tendency of SRC tumors to be higher grade and more locally advanced. However SRC histology does not appear to diminish the role of esophagectomy in the management of locoregionally confined esophageal cancer.

Abstract
OBJECTIVE Peritoneal carcinomatosis (PC) occurs frequently in patients with gastric adenocarcinoma (GAC) and confers a poor prognosis. Multiplex profiling of primary GACs has been insightful but the underpinnings of PC's development/progression remain largely unknown. We characterised exome/transcriptome/immune landscapes of PC cells from patients with GAC aiming to identify novel therapeutic targets. DESIGN We performed whole-exome sequencing (WES) and whole transcriptome sequencing (RNA-seq) on 44 PC specimens (43 patients with PC) including an integrative analysis of WES, RNA-seq, immune profile, clinical and pathological phenotypes to dissect the molecular pathogenesis, identifying actionable targets and/or biomarkers and comparison with TCGA primary GACs. RESULTS We identified distinct alterations in PC versus primary GACs, such as more frequent CDH1 and TAF1 mutations, 6q loss and chr19 gain. Alterations associated with aggressive PC phenotypes emerged with increased mutations in TP53, CDH1, TAF1 and KMT2C, higher level of 'clock-like' mutational signature, increase in whole-genome doublings, chromosomal instability (particularly, copy number losses), reprogrammed microenvironment, enriched cell cycle pathways, MYC activation and impaired immune response. Integrated analysis identified two main molecular subtypes: 'mesenchymal-like' and 'epithelial-like' with discriminating response to chemotherapy (31% vs 71%). Patients with the less responsive 'mesenchymal-like' subtype had high expression of immune checkpoint T-Cell Immunoglobulin And Mucin Domain-Containing Protein 3 (TIM-3), its ligand galectin-9, V-domain Ig suppressor of T cell activation (VISTA) and transforming growth factor-β as potential therapeutic immune targets. CONCLUSIONS We have uncovered the unique mutational landscape, copy number alteration and gene expression profile of PC cells and defined PC molecular subtypes, which correlated with PC therapy resistance/response. Novel targets and immune checkpoint proteins have been identified with a potential to be translated into clinics.

Mucin expression in gastric- and gastro-oesophageal signet-ring cell cancer: results from a comprehensive literature review and a large cohort study of Caucasian and Asian gastric cancer. Gastric Cancer 2020; 23:765-779. [PMID: 32488651 PMCID: PMC7438382 DOI: 10.1007/s10120-020-01086-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Accepted: 05/14/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND The literature on the prognostic relevance of signet-ring cell (SRC) histology in gastric cancer (GC) is controversial which is most likely related to inconsistent SRC classification based on haematoxylin-eosin staining. We hypothesised that mucin stains can consistently identify SRC-GC and predict GC patient outcome. METHODS We performed a comprehensive literature review on mucin stains in SRC-GC and characterised the mucin expression in 851 Caucasian GC and 410 Asian GC using Alcian Blue (AB)-Periodic Acid-Schiff (PAS), MUC2 (intestinal-type mucin), and MUC5AC (gastric-type mucin). The relationship between mucin expression and histological phenotype [poorly cohesive (PC) including proportion of SRCs, non-poorly cohesive (non-PC), or mucinous (MC)], clinicopathological variables, and patient outcome was analysed. RESULTS Depending on mucin expression and cut-offs, the positivity rates of SRC-GC reported in the literature varied from 6 to 100%. Patients with MUC2 positive SRC-GC or SRC-GC with (gastro)intestinal phenotype had poorest outcome. In our cohort study, PC with ≥ 10% SRCs expressed more frequently MUC2, MUC5AC, and ABPAS (p < 0.001, p = 0.004 and p < 0.001, respectively). Caucasians with AB positive GC or combined ABPAS-MUC2 positive and MUC5AC negative had poorest outcome (all p = 0.002). This association was not seen in Asian patients. CONCLUSIONS This is the first study to suggest that mucin stains do not help to differentiate between SRC-GC and non-SRC-GC. However, mucin stains appear to be able to identify GC patients with different outcome. To our surprise, the relationship between outcome and mucin expression seems to differ between Caucasian and Asian GC patients which warrants further investigations.

High Expression of TTYH3 is Related to Poor Clinical Outcomes in Human Gastric Cancer. J Clin Med 2019; 8:jcm8111762. [PMID: 31652813 PMCID: PMC6912211 DOI: 10.3390/jcm8111762] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2019] [Revised: 10/21/2019] [Accepted: 10/22/2019] [Indexed: 12/13/2022] Open
Abstract
Ion channels play important roles in regulating various cellular processes and malignant transformation. Expressions of some chloride channels have been suggested to be associated with patient survival in gastric cancer (GC). However, little is known about the expression and function of TTYH3, a gene encoding a chloride ion channel, in cancer progression. Here, we comprehensively analyzed the expression of TTYH3 and its clinical outcome in GC using publicly available cancer gene expression and patient survival data through various databases. We examined the differences of TTYH3 expression between cancers and their normal tissues using the Oncomine, UALCAN, and GEO (Gene Expression Omnibus) databases. TTYH3 expression was investigated from immunohistochemistry images using the Human Protein Atlas database. Copy number alterations and mutations of TTYH3 were analyzed using cBioPortal. The co-expression profile of TTYH3 in GC was revealed using Oncomine. The gene ontology and pathway analyses were done using those co-expressed genes via the Enrichr tool to explore the predicted signaling pathways in GC. TTYH3 mRNA and protein levels in GC were significantly greater than those in normal tissue. Kaplan–Meier analysis revealed the upregulation of TTYH3 expression, which was significantly correlated with worse patient survival. Collectively, our data suggest that TTYH3 might be a potential prognostic marker for GC patients.

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
Context The Staging and Prognostic Factors Committee of the International Association for the Study of Lung Cancer, in conjunction with the International Mesothelioma Interest Group, the International Thymic Malignancy Interest Group, and the Worldwide Esophageal Cancer Collaboration, developed proposals for the 8th edition of their respective tumor, node, metastasis (TNM) staging classification systems. Objective To review these changes and discuss issues for the reporting pathologist. Data Sources Proposals were based on international databases of lung (N = 94 708), with an external validation using the US National Cancer Database; mesothelioma (N = 3519); thymic epithelial tumors (10 808); and epithelial cancers of the esophagus and esophagogastric junction (N = 22 654). Conclusions These proposals have been mostly accepted by the Union for International Cancer Control and the American Joint Committee on Cancer and incorporated into their respective staging manuals (2017). The Union for International Cancer Control recommended implementation beginning in January 2017; however, the American Joint Committee on Cancer has deferred deployment of the eighth TNM until January 1, 2018, to ensure appropriate infrastructure for data collection. This manuscript summarizes the updated staging of thoracic malignancies, specifically highlighting changes from the 7th edition that are relevant to pathologic staging. Histopathologists should become familiar with, and start to incorporate, the 8th edition staging in their daily reporting of thoracic cancers henceforth.

Abstract
In the World Health Organization (WHO) classification, adenocarcinoma of esophagus comprises preinvasive type (dysplasia), adenocarcinoma, adenoid cystic carcinoma, adenosquamous carcinoma, and mucoepidermoid carcinoma. For adenocarcinoma, it is important to determine the grading of the cancer and histological variants such as signet ring adenocarcinoma. In the current day management of esophageal adenocarcinoma by neoadjuvant therapy, the histology of the cancer and the lymph nodal status may change after the therapy. Tumor regression grading systems could be used to assess the response to the neoadjuvant therapy in esophageal adenocarcinoma.

Abstract
Neoadjuvant therapy is increasingly used to treat patients with a wide variety of malignancies. Histologic evaluation of treated specimens provides important prognostic information and may guide subsequent chemotherapy. Neoadjuvant therapy is commonly employed in the treatment of locally advanced rectal adenocarcinoma, hepatic colorectal metastases, esophageal/esophagogastric junction carcinoma, and pancreatic ductal adenocarcinoma. Numerous tumor regression schemes have been used in these tumors and standardized approaches to evaluate these specimens are needed. In this review, the various tumor regression scoring systems that have been used in these organs are described and their associations with clinical outcomes are discussed. Recommendations regarding how to handle and report the histologic findings in these resections specimens are provided.

Influence of induction chemotherapy in trimodality therapy-eligible oesophageal cancer patients: secondary analysis of a randomised trial. Br J Cancer 2017; 118:331-337.

Abstract
Background: A randomised phase 2 trial of trimodality with or without induction chemotherapy (IC) in oesophageal cancer (EC) patients showed no advantage in overall survival (OS) or pathologic complete response rate. To identify subsets that might benefit from IC, a secondary analysis was done. Methods: The trial had accrued 126 patients (NCT 00525915). Recursive partitioning and proportional hazards regression with interactions were performed. Results: The median follow-up of surviving patients was 6.7 years and the median OS duration was 3.8 years (95% confidence interval (CI), 2.6-5.8 years). OS was associated with tumour length (P=0.03), cT (P=0.02), cN (P=0.04), clinical stage (P=0.01), and tumour grade (P<0.001). The effect of IC differed according to tumour grade. Among patients with well or moderately differentiated (WMD) ECs (n=59), the 5-year survival rate was 74% with IC and 50% without IC, P=0.001. IC had no effect on OS of patients with poorly differentiated (PD) ECs (31% and 28%, respectively; interaction, P=0.04; IC, P=0.03). In the multivariate reduced model, WMD with IC was an independent prognosticator for better OS (HR=0.41, 95% CI, 0.25-0.67; P=<0.001). The following four EC phenotypes emerged for OS: (1) very high risk (PD, cN2/N3), (2) high risk (PD, cN0/N1, stage cIII), (3) moderate risk (PD, cN0/N1, stage cI/II or WMD without IC), and (4) low risk (WMD with IC). The 5-year survival rates were 11%, 27%, 48%, and 74%, respectively (P<0.001). Conclusions: Our data show that IC significantly prolonged OS of WMD EC patients who undergo trimodality; prospective evaluation is needed.

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
Purpose Signet ring cell carcinoma of the esophagus (SRCCE) is an uncommon tumor associated with significant morbidity and mortality. There is still no consensus regarding cut-off values for tumor size, age and optimal treatment for SRCCE. Thus, we elucidated the current survival outcomes of patients with SRCCE and analyzed factors associated with prognosis. Methods A retrospective cohort study based on the SEER (The Surveillance, Epidemiology, and End Results) program database was conducted. We identified 537 patients (461 men and 76 women) newly diagnosed with SRCCE between January 2004 and December 2014. A multivariate Cox proportional hazards model was utilized to measure the mortality-associated risk factors in patients with SRCCE after adjusting for various variables. Results The 1-, 2- and 5-year disease-specific mortalities (DSM) were 51.6%, 67.6%, and 78.4%, respectively, and the median survival time was 12.0 months. The factors correlated with mortality hazard were marital status (unmarried versus married, Hazard Ratio (HR) = 1.443), tumor size (≥ 5 cm versus < 5 cm, HR = 1.444), tumor grade (high grade versus low grade, HR = 3.001), condition of primary tumor (T4 versus T1, HR = 2.178), regional lymph node metastasis (N1 versus N0, HR = 1.739), further metastasis (M1 versus M0, HR = 1.951) and chemotherapy (receiving chemotherapy versus no chemotherapy, HR = 0.464). Conclusions The contemporary 5-year DSM was 78.4%. Being unmarried, having a tumor size ≥ 5 cm, a high tumor grade, a score of T4 for tumor invasion of adjacent organs, a score of N1 for regional lymph node metastasis, a score of M1 for distant metastasis and no chemotherapy were independent predictors of high DSM.

Abstract
Answer questions and earn CME/CNE New to the eighth edition of the American Joint Committee on Cancer (AJCC) Cancer Staging Manual for epithelial cancers of the esophagus and esophagogastric junction are separate, temporally related cancer classifications: 1) before treatment decision (clinical); 2) after esophagectomy alone (pathologic); and 3) after preresection therapy followed by esophagectomy (postneoadjuvant pathologic). The addition of clinical and postneoadjuvant pathologic stage groupings was driven by a lack of correspondence of survival, and thus prognosis, between both clinical and postneoadjuvant pathologic cancer categories (facts about the cancer) and pathologic categories. This was revealed by a machine-learning analysis of 6-continent data from the Worldwide Esophageal Cancer Collaboration, with consensus of the AJCC Upper GI Expert Panel. Survival is markedly affected by histopathologic cell type (squamous cell carcinoma and adenocarcinoma) in clinically and pathologically staged patients, requiring separate stage grouping for each cell type. However, postneoadjuvant pathologic stage groups are identical. For the future, more refined and granular data are needed. This requires: 1) more accurate clinical staging; 2) innovative solutions to pathologic staging challenges in endoscopically resected cancers; 3) integration of genomics into staging; and 4) precision cancer care with targeted therapy. It is the responsibility of the oncology team to accurately determine and record registry data, which requires eliminating both common errors and those related to incompleteness and inconsistency. Despite the new complexity of eighth edition staging of cancers of the esophagus and esophagogastric junction, these key concepts and new directions will facilitate precision cancer care.

Abstract
Objectives The aim of this study was to analyze the clinicopathological features and prognosis of esophageal signet ring cell (SRC) carcinoma in China. Methods Patients with poorly differentiated adenocarcinoma were identified in two hospitals from January 2006 to June 2016. The patients were divided into three groups according to component of SRCs: SRC≥50% group, SRC < 50% group and non-SRC poorly differentiated adenocarcinoma group. Results Fifty-seven patients had carcinoma (SRC≥50%), and 79 patients had tumors containing <50% SRCs, and 535 patients was in non-SRC poorly differentiated adenocarcinoma group. There were no significant differences among the three groups in clinicopathological characteristics. Patients in SRC≥50% group had a lower overall survival rate (at 3-year 37.6%versus71.1%; at 5-year 0% versus 43.3%; p<0.001) compared with the control group. Even survival outcome of patients in SRC < 50%was inferior to that of in control group (at 3-year 53.0%versus71.1%; at 5-year 25.9% versus 43.3%; p<0.001). Female sex, large tumor size and increasing TNM stage were independent prognostic factors for SRC ≥50% esophageal carcinoma patients. Conclusions The incidence of esophageal SRC carcinoma is relatively rare and the worst outcome is observed in the SRC≥ 50% group. It is necessary to explore new therapeutic modalities to achieve further improvements in the clinical outcome of these patients.

Abstract
As well known, signet-ring cell carcinoma (SRCC) is a rare histological subtype of colorectal adenocarcinoma, which has been associated with poor prognosis and resistant to non-surgery therapy compared with common adenocarcinoma. In this study, we assessed the effect of preoperative radiotherapy (PRT) for locally advanced rectal SRCC in a large patient group from the Surveillance, Epidemiology, and End Results program (SEER, 1988–2011) database. SRCC was found in 0.9% (n = 622) rectal cancer (RC) patients in our study. In the PRT setting, SRCC had significantly worse cancer-specific survival than mucinous adenocarcinoma and nonmucinous adenocarcinoma patients (log-rank, P < 0.001). In terms of SRCC, stage III RC patients benefited from PRT (log-rank, P < 0.001) while stage II did not (P = 0.095). The multivariate Cox proportional hazard model showed that PRT was an independent benefit factor in stage III rectal SRCC patients (HR, 0.611; 95% CI, 0.407–0.919; P = 0.018). In conclusion, SRCC was an independent predictor of poor prognosis in stage III RC patients, but not in stage II. In the PRT setting of locally advanced RC, SRCC patients had significantly worse prognosis. PRT was an independent prognostic factor associated with improved survival in stage III rectal SRCC.

Abstract
The 8th edition of the American Joint Committee on Cancer (AJCC) staging of epithelial cancers of the esophagus and esophagogastric junction (EGJ) presents separate classifications for clinical (cTNM), pathologic (pTNM), and postneoadjuvant (ypTNM) stage groups. Histopathologic cell type markedly affects survival of clinically and pathologically staged patients, requiring separate groupings for each cell type, but ypTNM groupings are identical for both cell types. Clinical categories, typically obtained by imaging with minimal histologic information, are limited by resolution of each method. Strengths and shortcomings of clinical staging methods should be recognized. Complementary cytology or histopathology findings may augment imaging and aid initial treatment decision-making. However, prognostication using clinical stage groups remains coarse and inaccurate compared with pTNM. Pathologic staging is losing its relevance for advanced-stage cancer as neoadjuvant therapy replaces esophagectomy alone. However, it remains relevant for early-stage cancers and as a staging and survival reference point. Although pathologic stage could facilitate decision-making, its use to direct postoperative adjuvant therapy awaits more effective treatment. Prognostication using pathologic stage groups is the most refined of all classifications. Postneoadjuvant staging (ypTNM) is introduced by the AJCC but not adopted by the Union for International Cancer Control (UICC). Drivers of this addition include absence of equivalent pathologic (pTNM) categories for categories peculiar to the postneoadjuvant state (ypT0N0-3M0 and ypTisN0-3M0), dissimilar stage group compositions, and markedly different survival profiles. Thus, prognostication is specific for patients undergoing neoadjuvant therapy. The role of ypTNM classification in additional treatment decision-making is currently limited. Precision cancer care advances are necessary for this information to be clinically useful.

Abstract
Little is known regarding the prognostic impact of the signet ring cell (SRC) histotype on negative lymph nodes (LNs) in gastric cancer (GC). In this study, we aimed to investigate the differences between SRC and non-SRC GC patients without LN metastasis. The medical records of patients with GC who underwent gastrectomy at Sun Yat-Sen University Cancer Centre from 1996 to 2012 were reviewed to analyse the clinicopathologic characteristics associated with survival. A total of 480 cases of GC patients without LN metastasis were identified, which included 90 SRC GC patients and 390 non-SRC GC patients. Between the two groups, there were a host of significant differences in the American Joint Committee on Cancer, 7th edition (AJCC) stage. We found that SRC histology was correlated with a poor prognosis in terms of recurrence in node-negative GC patients and that SRC histologic analysis combined with AJCC staging maybe an effectual method for prediction of the recurrence rate. Additionally, we found that SRC GC presents a more dismal overall prognosis in patients with perineural or vascular invasion.

Abstract
Background: Multimodal therapeutic strategies have improved the outcome of peritoneal metastases (PM). However, objective assessment of therapy response remains difficult in PM, since radiological studies have a poor accuracy for low-volumetric disease. There is an obvious need for a histological gold standard allowing assessment of tumor response to treatment in PM. Content: We propose to perform peritoneal punch biopsies with a diameter of 3 to 5 mm in all four abdominal quadrants. We propose a four-tier Peritoneal Regression Grading Score (PRGS), defined as Grade 1: complete response (absence of tumor cells), Grade 2: major response (major regression features, few residual tumor cells), Grade 3: minor response (some regressive features but predominance of residual tumor cells), Grade 4: no response (tumor cells without any regressive features). Acellular mucin and infarct-like necrosis should be regarded as regression features. We recommend reporting the mean and the worst value of the regression grades obtained. When complete tumor response is suspected intraoperatively, a peritoneal cytology should be sampled. Summary: A generic, unique score for the assessment of histological tumor response to chemotherapy in PM makes sense because of the clinical impact of histological response to therapy and because the organ of metastasis (peritoneum) is the same. By adopting PRGS, different centers will be able to use a uniform terminology and grading that will allow meaningful comparison of their results. Outlook: PRGS has now to be validated in several gastrointestinal and gynecological cancer types and may be useful both in clinical and research settings.

Abstract
CONTEXT Esophageal cancer continues to be one of the most lethal of all gastrointestinal malignancies. Its prognostic parameters are based on the gross and histopathologic examination of resected specimens by pathologists. OBJECTIVE To describe the implications of appropriate handling and examination of endomucosal resection and esophagectomy specimens from patients with esophageal carcinoma while considering the implications of the surgical techniques used to obtain such specimens. Parameters include histopathologic findings necessary for accurate staging, differences in the assessment of margins, residual malignancy, and criteria to evaluate for tumor regression after chemoradiation therapy as well as the role of immunohistochemistry and the judicious use of frozen sections. DATA SOURCES Sources were a review of the literature and the authors' experience handling these types of specimens. CONCLUSIONS Examining surgical specimens of the esophagus is critical in the management of patients with esophageal carcinoma, and it requires careful consideration of the diagnostic pitfalls, staging-related parameters, and results of molecular tests.

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.

Predictors of Disease Recurrence and Survival in Esophageal Adenocarcinomas With Complete Response to Neoadjuvant Therapy. Am J Surg Pathol 2015; 39:1085-92.

Abstract
Complete response to neoadjuvant therapy, determined by pathologic examination of the resection specimen (pCR), is associated with a favorable outcome in esophageal adenocarcinomas (EAC), but there is significant heterogeneity in survival reported within this group. Our aim was to determine predictors of disease recurrence (DR) and survival in EAC patients with pCR to neoadjuvant therapy. A total of 93 EAC patients with pCR to neoadjuvant therapy were identified, and a predetermined set of clinicopathologic variables was examined, including patient age, sex, tumor location, pretreatment tumor size, endoscopic ultrasound T and N stage, histologic tumor type, and grade in pretreatment biopsies. The esophagectomy specimens were evaluated for the extent of sampling of the tumor bed, depth of treatment-related changes, presence of treatment effect in lymph nodes, and the total number of lymph nodes examined. Complete histologic examination of the tumor bed was the most significant predictor of favorable outcome for both DR (hazard ratio [HR]=0.42; 95% confidence interval [CI]: 0.21-0.82; P=0.011) and disease-specific mortality (HR=0.40; 95% CI: 0.22-0.70; P<0.01). The presence of a high-grade adenocarcinoma component in pretreatment biopsies (HR=2.19; 95% CI: 1.22-3.94; P<0.01) was associated with a higher disease-specific mortality, and involvement of the gastroesophageal junction (HR=2.37; 95% CI: 1.11-5.06; P=0.026) was associated with a higher rate of DR. Heterogeneity in outcomes for EAC patients with pCR to therapy can be explained by adequacy of histologic examination of the tumor bed, high tumor grade, and involvement of the gastroesophageal junction.

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 To clarify the biologic behavior of esophageal signet ring cell (SRC) carcinomas of the esophagus and gastroesophageal junction (GEJ). To evaluate the accuracy of pretreatment biopsies in diagnosing true SRC carcinoma. BACKGROUND In contrast with gastric cancer, little is known about the biologic behavior and prognosis of SRC. METHODS All adenocarcinomas (ADC) of the esophagus and GEJ-patients undergoing primary resection between 1990 and 2009 were included (n = 920). Specimens containing SRCs (n = 114) were classified according to World Health Organization criteria (>50% SRC or <50% SRC). RESULTS Thirty-two patients showed more than 50% SRC and 71 patients showed less than 50% SRC. Overall cancer-specific 5-year survival was worse for SRC (22.4%, P < 0.0001) and for SRC > 50% (13.6%, P = 0.0001) compared with ADC. Complete resection was achieved in 86.5% of patients (n = 697) in ADC, 69.5% (n = 57) in SRC < 50%, and 78.1% (n = 25) in SRC > 50% (vs ADC, respectively, P < 0.0001 and P = 0.1801). In 379 pN + R0 patients, the median number of positive lymph nodes was comparable between ADC and SRC < 50% (4 vs 5, P = 0.207) or SRC > 50% (4 vs 8, P = 0.077). Compared with ADC, SRC > 50% showed more pN3's (30% vs 61%, P = 0.006), higher recurrence (56% vs 42% for ADC, P = 0.003), and local-regional recurrences (29% vs 16%, P = 0.002). Pretreatment biopsies were unreliable to define the presence of SRC > 50% (sensitivity = 56.3%, positive predictive value = 43.9%). CONCLUSIONS SRCs are aggressive neoplasms associated with poorer prognosis than other ADCs after primary esophagectomy. Because our data suggest that pretreatment biopsies failed to reliably define presence of SRC > 50%, presence of SRCs in pretreatment biopsies seems to be of no use to define treatment strategy or prognosis.

Abstract
Management of esophageal cancer has evolved since the two last decades. Esophagectomy remains the primary treatment for early stage esophageal cancer although its specific role in superficial cancers is still under debate since the development of endoscopic mucosal treatment. To date, there is strong evidence to consider that locally advanced cancers should be recommended for a multimodal treatment with a neoadjuvant chemotherapy or a combined chemoradiotherapy (CRT) followed by surgery. For locally advanced squamous cell carcinoma or for a part of adenocarcinoma, some centers have proposed treating with definitive CRT to avoid related-mortality of surgery. In case of persistent or recurrent disease, a salvage esophagectomy remains a possible option but this procedure is associated with higher levels of perioperative morbidity and mortality. Despite the debate over what constitutes the best surgical approach (transthoracic versus transhiatal), the current question is if a minimally procedure could reduce the periopertive morbidity and mortality without jeopardizing the oncological results of surgery. Since the last decade, minimally invasive esophagectomy (MIE) or hybrid operations are being done in up to 30% of procedures internationally. There are some consistent data that MIE could decrease the incidence of the respiratory complications and decrease the length of hospital-stay. Nowadays, oncologic outcomes appear equivalent between open and minimally invasive procedures but numerous phase III trials are ongoing.

Abstract
Gastroesophageal cancers (such as esophageal, gastric and gastroesophageal-junction -GEJ- lesions) are worldwide a leading cause of death being relatively rare but highly aggressive. In the past years, a clear shift in the location of upper gastrointestinal tract tumors has been recorded, both affecting the scientific research and the modern clinical practice. The integration of pre- or peri-operative multimodal approaches, as radiotherapy and chemotherapy (often combined), seems promising to further improve clinical outcome for such presentations. In the past, the definition of GEJ led to controversies and confusion: GEJ tumors have been managed either grouped to gastric or esophageal lesions, following slightly different surgical, radiotherapeutic and systemic approaches. Recently, the American Joint Committee on Cancer (AJCC) changed the staging and classification system of GEJ to harmonize some staging issues for esophageal and gastric cancer. This review discusses the most relevant historical and recent evidences of neoadjuvant treatment involving Radiotherapy for GEJ tumors, and describes the efficacy of such treatment in the frame of multimodal integrated therapies, from the new point of view of the recent classification of such tumors.

Is preoperative chemotherapy followed by surgery the appropriate treatment for signet ring cell containing adenocarcinomas of the esophagogastric junction and stomach? Ann Surg Oncol 2014; 21:1739-48.

Abstract
BACKGROUND Recent data suggest primary resection as the preferable approach in patients with signet ring cell gastric cancer (SRC). The aim of our retrospective exploratory study was to evaluate the influence of SRC on prognosis and response in esophagogastric adenocarcinoma treated with neoadjuvant chemotherapy. METHODS A total of 723 locally advanced esophagogastric adenocarcinomas (cT3/4 N any) documented in a prospective database from two academic centers were classified according to the WHO definition for SRC (more than 50 % SRC) and analyzed for their association with response and prognosis after neoadjuvant treatment. RESULTS A total of 235 tumors (32.5 %) contained SRC. Median survival of SRC was 26.3 compared with 46.6 months (p < 0.001) for non-SRC. SRC were significantly associated with female gender, gastric localization, advanced ypT and R1/2 categories, and lower risk of surgical complications and anastomotic leakage (each p < 0.001). Clinical (21.1 vs. 33.7 %, p = 0.001) and histopathological response (less than 10 % residual tumor: 16.3 vs. 28.9 %, p < 0.001) were significantly less frequent in SRC. Clinical response (p = 0.003) and complete histopathological response (pCR) (3.4 %) (p = 0.003) were associated with improved prognosis in SRC. Clinical response, surgical complications, ypTN categories, but not SRC were independent prognostic factors in forward Cox regression analysis in R0 resected patients. Risk of peritoneal carcinomatosis was increased (p < 0.001), while local (p = 0.015) and distant metastases (p = 0.02) were less frequent than in non-SRC. CONCLUSIONS Prognosis of SRC is unfavorable. Although response to neoadjuvant chemotherapy is rare in SRC, it is associated with improved outcome. Thus, chemotherapy might not generally be abandoned in SRC. A stratification based on SRC should be included in clinical trials.

Abstract
Mucin core proteins (MUCs) are expressed in tissue-specific patterns in the gastrointestinal tract and expression is deregulated in Barrett's metaplasia. Based on differential expression, MUCs have been used to classify adenocarcinomas into distinct phenotypes (eg, intestinal, gastric, pancreaticobiliary, etc). Because MUC expression patterns carry prognostic significance in other tumors, we evaluated MUC expression in superficial adenocarcinomas of the gastroesophageal junction and esophagus (EAC) to determine whether there are differences in outcome associated with MUC subtype in this potentially curable subset of EAC. We classified 142 resected, superficial (T1) EAC based on their pattern of expression of MUC2, MUC5AC, MUC6 and MUC1. The association between survival and MUC expression pattern was determined in univariate and multivariate analyses. The MUC2 positive "intestinal" phenotype was associated with significantly worse prognosis in submucosal EAC (hazard ratio 2.2, 95% confidence interval 1.2-4.2), independent of node stage and other prognostic factors. MUC2 expression in submucosal EAC also showed significantly accelerated time to recurrence (hazard ratio 2.8, 95% confidence interval 1.2-6.8) after adjusting for node stage. The classification of superficial EAC by MUC protein expression has prognostic significance. MUC2 expression is an adverse prognostic indicator in submucosal EAC, independent of node stage and other prognostic factors.

[PMID: 23987898 DOI: 10.1016/j.athoracsur.2013.06.047] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2013] [Revised: 06/04/2013] [Accepted: 06/06/2013] [Indexed: 01/15/2023]
Abstract
BACKGROUND Adenocarcinoma with signet ring cell (SRC) features has been reported to be a poor prognostic marker in gastric and colorectal carcinomas. Although uncommon in the esophagus, SRC histology, interestingly, has been correlated with improved survival. Our impression has been that the incidence of esophageal adenocarcinomas with SRC features is increasing and is associated with worse outcomes. We hypothesize that patients with SRC histology present with more advanced disease, respond less well to induction therapy, and have decreased survival after resection compared with patients with non-SRC adenocarcinoma. METHODS The medical records of 151 consecutive patients who underwent resection for adenocarcinoma of the esophagus or gastroesophageal junction in a prospectively maintained database from 1998 to 2011 were reviewed. Outcomes of 23 patients (15%) with SRC histology (21 men, 2 women; average age, 66 years) were compared with 128 patients (85%) with non-SRC adenocarcinoma (116 men, 12 women; average age, 63 years). Overall survival, stage-specific survival, and response to induction therapy were evaluated. Cox regression multivariate analysis was used to identify independent predictors of 3-year survival. RESULTS SRC and non-SRC patients were evenly matched for clinical and tumor characteristics. Downstaging achieved with induction therapy was 13.3% (2 of 15) in SRC histology patients vs 67.1% (53 of 79) in non-SRC patients (p ≤ 0.001). Patients with SRC histology who did not respond well to induction treatment demonstrated strong trends toward a worse 3-year survival than patients with non-SRC adenocarcinoma (p = 0.084). The overall 3-year survival was 65.6% in patients without SRC histology vs 34.8% in those with SRC (p = 0.006). Patients with pathologic stage II or III and SRC histology had a 3-year survival of 27.3% compared with 57.4% in patients with non-SRC adenocarcinoma (p = 0.01). Multivariate analysis showed SRC histology trended toward significance as an independent risk factor for poor survival (p = 0.060). CONCLUSIONS Patients with adenocarcinoma of the esophagus or gastroesophageal junction and SRC histology respond less well to induction therapy and have decreased overall survival compared with patients with non-SRC histology.
