Abstract
We report a case of linitis plastica (LP) with synchronous bilateral Krukenberg Tumours in a young woman, which could be resected fully. Such a case is rarely reported because of rarity (LP), dismal prognosis (LP and Krukenberg Tumours), nonresectability due to peritoneal spread at presentation, and lack of clear treatment protocols (LP and Krukenberg Tumours). This case report suggests that LP, with Krukenberg Tumours, can achieve complete resection in a select subset of cases; this may improve survival.

Appl Immunohistochem Mol Morphol 2023; 31:583-589. [PMID: 37698957 DOI: 10.1097/pai.0000000000001152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Accepted: 07/26/2023] [Indexed: 09/14/2023]
Abstract
INTRODUCTION The Peritoneal Regression Grading Score (PRGS) is a 4-tied histologic regression grading score for determining the response of peritoneal metastasis to chemotherapy. Peritoneal biopsies in every abdominal quadrant are recommended. A positive therapy response is defined as a decreasing or stable mean PRGS between 2 therapy cycles. The added value of periodic acid satin (PAS) and Ber-EP4 staining over HE staining for diagnosing PRGS1 (the absence of vital tumor cells) is unclear. MATERIALS AND METHODS A total of 339 biopsies obtained during 76 laparoscopies in 33 patients with peritoneal metastasis of gastric cancer were analyzed. Biopsies classified as PRGS 1 (no residual tumor, n=95) or indefinite (n=50) were stained with PAS, and remaining indefinite or PRGS1 cases additionally stained with BerEP4. RESULTS After PAS-staining tumor cells were detected in 28 out of 145 biopsies (19%), the remaining 117 biopsies were immunostained with Ber-EP4. Tumor cells were detected in 22 biopsies (19%). In total, additional staining allowed the detection of residual tumor cells in 50 out of 339 biopsies (15%) and changed the therapy response assessment in 7 out of 33 (21%) patients. CONCLUSIONS In summary, 25% (24 out of 95) of initially tumor-free samples (PRGS1) showed residual tumor cells after additional staining with PAS and/or BerEp4. Immunohistochemistry provided important additional information (the presence of tumor cells) in 22 of all 339 biopsies (11.2%). Further staining reduced the instances of unclear diagnosis from 50 to 0 and changed the therapy response assessment in 7 out of 33 patients (21%). We recommend additional staining in PRGS1 or unclear cases.

Abstract
PURPOSE The Borrmann classification system is widely used to classify advanced gastric cancer (GC). No studies have focused on the relationship between Borrmann type and response to preoperative therapy. METHODS Patients with advanced GC who received preoperative therapy followed by curative-intent gastrectomy from September 2016 through September 2021 were identified. Clinicopathologic characteristics were compared by Borrmann type. Logistic regression models were fit to analyze the relationship between Borrmann type and pCR rate. RESULTS Of the 227 patients who underwent gastrectomy during the period studied, 73 had pretreatment endoscopic images available for analysis. We classified the tumors as follows: Borrmann type 1, 4 (6%); type 2, 17 (23%); type 3, 33 (45%); and type 4, 19 (26%). Nine patients (12%) achieved pCR; 6 of these (67%) had type 1/2 GC and 3 (33%) had type 3. Multivariable logistic regression showed that Borrmann type 3/4 was the only independent factor associated with pCR (odds ratio 0.12; p = 0.023), but 2-year overall survival rates did not differ by Borrmann type (p = 0.216). CONCLUSION Patients with Borrmann type 3/4 advanced GC have a lower likelihood of achieving pCR after preoperative therapy than those with type 1/2 GC. Determining the Borrmann type preoperatively can guide treatment decision-making.

Abstract
We report the case of a woman in her 50s who underwent, 5 years prior, a total gastrectomy after neoadjuvant chemotherapy for diffuse-type gastric cancer diagnosed during a workup for isolated gastric primary light chain (AL) amyloidosis. At the time of diagnosis, immunoglobulins light chain measurements and bone marrow biopsy were performed to rule out multiple myeloma and came back normal. Three years later, the patient developed systemic amyloidosis involving the heart and the lungs, after which she developed multiple myeloma. Isolated amyloid deposits in the stomach are a rare finding. While AL amyloidosis is frequently found in concomitance with multiple myeloma, late progression of primary AL amyloidosis to systemic amyloidosis and multiple myeloma is uncommon.

Abstract
Gastric cancer is ranked fifth among the most commonly diagnosed cancers, and is the fourth leading cause of cancer-related deaths worldwide. The majority of gastric cancers are sporadic, while only a small percentage, less than 1%, are hereditary. Hereditary diffuse gastric cancer (HDGC) is a rare malignancy, characterized by early-onset, highly-penetrant autosomal dominant inheritance mainly of the germline alterations in the E-cadherin gene (CDH1) and β-catenin (CTNNA1). In the present study, we provide an overview on the molecular basis of HDGC and outline the essential elements of genetic counseling and surveillance. We further provide a practical summary of current guidelines on clinical management and treatment of individuals at risk and patients with early disease.

Abstract
While the incidence of gastric cancer (GC) in general has decreased worldwide in recent decades, the incidence of diffuse cancer historically comprising poorly cohesive cells-GC (PCC-GC) and including signet ring cell cancer is rising. Literature concerning PCC-GC is scarce and unclear, mostly due to a large variety of historically used definitions and classifications. Compared to other histological subtypes of GC, PCC-GC is nevertheless characterized by a distinct set of epidemiological, histological and clinical features which require a specific diagnostic and therapeutic approach. The aim of this review was to provide an update on the definition, classification and therapeutic strategies of PCC-GC. We focus on the updated histological definition of PCC-GC, along with its implications on future treatment strategies and study design. Also, specific considerations in the diagnostic management are discussed. Finally, the impact of some recent developments in the therapeutic management of GC in general such as the recently validated taxane-based regimens (5-Fluorouracil, leucovorin, oxaliplatin and docetaxel), the use of hyperthermic intraperitoneal chemotherapy as well as pressurized intraperitoneal aerosol chemotherapy and targeted therapy have been reviewed in depth for their relative importance for PCC-GC in particular.

Abstract
Peritoneal dissemination is a common form of gastric cancer (GC) recurrence, despite surgery with curative intent. This study aimed to evaluate the prognostic value of intraperitoneal lavage One-Step Nucleic Acid Amplification (OSNA) assay in advanced GC patients. OSNA assay targeting CK-19 mRNA was applied to detect free cancer cells (FCC) in intraperitoneal lavage samples obtained during gastrectomy. A total of 82 GC patients were enrolled to investigate the correlation between OSNA assay and patient's prognosis. Of the 82 patients, OSNA assay was positive in 25 (30.5%) patients. The median OS in OSNA positive patients was significantly lower than in OSNA negative patients (19 vs 45 months). Positive OSNA assay result was a significant unfavourable prognostic factor in both, univariable (HR 3.45, 95% CI 0.95-12.48; p = 0.0030) and multivariable analysis (HR 3.10, 95% CI 1.22-8.54; p = 0.0298). Positive OSNA assay in intraperitoneal lavage is a valuable indicator of poor survival in advanced GC patients after multimodal treatment. After further confirmation on larger sample size, OSNA assay of peritoneal washings could be considered an adjunct tool to conventional cytology, the current gold standard, to provide precise intraoperative staging and additional prognostic information.

Abstract
BACKGROUND Gastric linitis plastica (GLP) is a diffuse infiltrating type of gastric adenocarcinoma. It is associated with a poor prognosis and a five-year survival of 3-10%. The infiltrating profile of this tumor explains the low yield of the superficial mucosal biospies. The objective of this study was to investigate the role of endoscopic ultrasound-fine needle biopsy (EUS-FNB) in the diagnosis of GLP. METHODS We performed a retrospective analysis including all patients who had an EUS-FNB, at a tertiary referral center, over the last 3 years. The primary outcome was the sensitivity of EUS-FNB in patients with suspected GLP. RESULTS Between January 2017 and December 2020, 34 patients had an EUS-FNB for suspected GLP. Ten patients had a diagnostic of GLP. This diagnosis was obtained by EUS-FNB in 90% (9/10) of the cases. Eight patients had at least one previous esophagogastroduodenoscopy (EGD) with negative mucosal biopsies. Gastric EUS-FNB helped diagnose other serious conditions in 47% (16/34) of cases with inconclusive mucosal biopsies. CONCLUSION Gastric EUS-FNB in patients with suspected GLP and normal endoscopic mucosal biopsies may lead to a positive diagnosis of GLP in 90% of cases without notable adverse events. This technique should be considered as a second step in the setting of suspicion of GLP after inconclusive mucosal biopsies.

Diagnostic Value of EUS-Guided Fine-Needle Aspiration Biopsy for Gastric Linitis Plastica with Negative Endoscopic Biopsy. J Clin Med 2021; 10:jcm10163716.

Abstract
Due to the tendency of gastric linitis plastica (GLP) to cause extensive submucosal infiltration, a superficial endoscopic biopsy sometimes yields no evidence of malignancy, hindering definite diagnosis. The present study was a single-center retrospective analysis of 54 consecutive patients diagnosed with GLP between 2016 and 2020 to evaluate EUS-guided fine-needle aspiration (EUS-FNA) biopsy outcomes in patients with negative endoscopic biopsy findings. A pathological GLP diagnosis was achieved by endoscopic biopsy in 40 patients (74.1%). EUS-FNA biopsy with a 22-gauge needle was performed in 13 of the remaining 14 patients, and GLP diagnosis was confirmed in 10 patients, with a median of three needle passes. The remaining four patients were laparoscopically diagnosed with GLP. The diagnostic ability of EUS-FNA biopsy for GLP was 76.9%, and EUS-FNA biopsy contributed to GLP diagnosis in 18.5% (10/54) of all cases. None of the 13 patients exhibited EUS-FNA biopsy-related adverse events. Univariable and multivariable analyses revealed an absence of superficial ulcerations as a predictor of false-negative endoscopic biopsy findings in patients with GLP. These results suggest EUS-FNA biopsy as a minimally invasive and safe alternative diagnostic modality for GLP in cases where conventional endoscopic biopsy fails to verify malignancy, although prospective studies with larger cohorts are warranted to confirm these findings.

Abstract
Gastric cancer is still an important disease causing many deaths worldwide, although there has been a marked reduction in prevalence during the last few decades. The decline in gastric cancer prevalence is due to a reduction in Helicobacter pylori infection which has occurred for at least 50 years. The most probable mechanism for the carcinogenic effect of H. pylori is hypergastrinemia since H. pylori infected individuals do not have increased risk of gastric cancer before the development of oxyntic atrophy. When atrophy has developed, the carcinogenic process continues independent of H. pylori. Autoimmune gastritis also induces oxyntic atrophy leading to marked hypergastrinemia and development of ECL cell neoplasia as well as adenocarcinoma. Similarly, long-term treatment with efficient inhibitors of acid secretion like the proton pump inhibitors (PPIs) predisposes to ECL cell neoplasia of a different degree of malignancy. Contrasting the colon where most cancers develop from polyps, most polyps in the stomach have a low malignant potential. Nevertheless, gastric polyps may also give rise to cancer and have some risk factors and mechanisms in common with gastric cancer. In this overview the most common gastric polyps, i.e., hyperplastic polyps, adenomatous polyps and fundic gland polyps will be discussed with respect to etiology and particularly use of PPIs and relation to gastric carcinogenesis.

Abstract
Background Gastric linitis plastica (GLP) is characteristic by its poor prognosis and highly aggressive characteristics compared with other types of gastric cancer (GC). However, the guidelines have not yet been distinguished between GLP and non-GLP. Methods A total of 342 eligible patients with GLP identified in the Surveillance, Epidemiology, and End Results (SEER) dataset were randomly divided into training set (n=298) and validation set (n=153). A nomogram would be developed with the constructed predicting model based on the training cohort's data, and the validation cohort would be used to validate the model. Principal component analysis (PCA) was used to evaluate the differences between groups. Cox regression and LASSO (least absolute shrinkage and selection operator) were used to construct the models. Calibration curve, time-dependent receiver operating characteristic (ROC) curve, concordance index (C-index) and decision curve analysis (DCA) were used to evaluate the predicting performance. Restricted mean survival time (RMST) was used to analyze the curative effect of adjuvant therapy. Results For patients in training cohort, univariable and multivariable Cox analyses showed that age, examined lymph nodes (LN.E), positive lymph nodes (LN.P), lesion size, combined resection, and radiotherapy are independent prognostic factors for overall survival (OS), while chemotherapy can not meet the proportional hazards (PHs) assumption; age, race, lesion size, LN.E, LN.P, combined resection and marital status are independent prognostic factors for cancer-specific survival (CSS). The C-index of the nomogram was 0.678 [95% confidence interval (CI), 0.660-0.696] and 0.673 (95% CI, 0.630-0.716) in the training and validation cohort, respectively. Meanwhile, the C-index of the CSS nomogram was 0.671 (95% CI, 0.653-0.699) and 0.650 (95% CI, 0.601-0.691) in the training and validation cohort for CSS, respectively. Furthermore, the nomogram was well calibrated with satisfactory consistency. RMST analysis further determined that chemotherapy and radiotherapy might be beneficial for improving 1- and 3-year OS and CSS, but not the 5-year CSS. Conclusions We developed nomograms to help predict individualized prognosis for GLP patients. The new model might help guide treatment strategies for patients with GLP.

Abstract
Purpose Type 4 gastric cancer (GC) has a very poor prognosis even after curative resection, and the survival benefit of splenectomy for splenic hilar lymph node (LN; #10) dissection in type 4 GC remains equivocal. This study aimed to clarify the clinical significance of splenectomy for #10 dissection in patients with type 4 GC. Materials and Methods The data of a total of 56 patients with type 4 GC who underwent total gastrectomy with splenectomy were retrospectively analyzed. Postoperative morbidity, state of LN metastasis, survival outcomes, and therapeutic value index (TVI) of each LN station were evaluated. TVI was calculated by multiplying the incidence of LN metastasis at each nodal station and the 5-year overall survival (OS) of patients who had metastasis to each node. Results Overall, the postoperative morbidity rate was 28.6%, and the incidence of #10 metastasis in the patients was 28.6%. The 5-year OS rate for all patients was 29.9%, and most patients developed peritoneal recurrence. Moreover, the 5-year OS rates with and without #10 metastasis were 6.7% and 39.1% (median survival time, 20.4 vs. 46.0 months; P=0.006). The TVI of #10 was as low as 1.92. Conclusions The clinical significance of splenectomy in the dissection of #10 for type 4 GC is limited and splenectomy for splenic hilar dissection alone should be omitted.

Abstract
Background To explore the efficacy of treatment strategies for non-metastatic gastric linitis plastica (GLP). Methods Patients with non-metastatic GLP from 2004 to 2014 were identified from the National Cancer Database (NCDB). We compared overall survival (OS) of those patients who received different treatments, including surgery alone, a combination of surgery with chemotherapy and/or radiotherapy (S + C/R), chemotherapy and/or radiotherapy (C/R), and no treatment. Results The cohort included 474 patients with non-metastatic GLP. Overall, the median survival was significantly different among four groups (13.90 months in S + C/R, 8.38 months in surgery alone, 8.94 months in C/R and 2.50 months in no treatment). Then, we compared the efficacy of surgery alone and surgery with postoperative chemotherapy and/or radiotherapy (S + post C/R). When the tumor size was greater than 8 cm in stage III patients, S + post C/R was associated with a better survival benefit than surgery alone. S + post C/R also conferred an obvious survival advantage compared to surgery alone for R0 patients with positive lymph nodes and patients with positive margins. Conclusions Surgery plays the fundamental role in improving the OS of patients with non-metastatic GLP. S + post C/R would benefit patients in stage III with large-sized tumors (>8 cm), patients with negative margins and positive lymph nodes, and/or patients with positive margins.

Peri-operative Outcomes and Survival Following Palliative Gastrectomy for Gastric Cancer: a Systematic Review and Meta-analysis. J Gastrointest Cancer 2020; 52:41-56. [PMID: 32959118 PMCID: PMC7900337 DOI: 10.1007/s12029-020-00519-4] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/09/2020] [Indexed: 02/03/2023]
Abstract
BACKGROUND Many patients with gastric cancer present with late stage disease. Palliative gastrectomy remains a contentious intervention aiming to debulk tumour and prevent or treat complications such as gastric outlet obstruction, perforation and bleeding. METHODS We conducted a systematic review of the literature for all papers describing palliative resections for gastric cancer and reporting peri-operative or survival outcomes. Data from peri-operative and survival outcomes were meta-analysed using random effects modelling. Survival data from patients undergoing palliative resections, non-resective surgery and palliative chemotherapy were also combined. This study was registered with the PROSPERO database (CRD42019159136). RESULTS One hundred and twenty-eight papers which included 58,675 patients contributed data. At 1 year, there was a significantly improved survival in patients who underwent palliative gastrectomy when compared to non-resectional surgery and no treatment. At 2 years following treatment, palliative gastrectomy was associated with significantly improved survival compared to chemotherapy only; however, there was no significant improvement in survival compared to patients who underwent non-resectional surgery after 1 year. Palliative resections were associated with higher rates of overall complications versus non-resectional surgery (OR 2.14; 95% CI, 1.34, 3.46; p < 0.001). However, palliative resections were associated with similar peri-operative mortality rates to non-resectional surgery. CONCLUSION Palliative gastrectomy is associated with a small improvement in survival at 1 year when compared to non-resectional surgery and chemotherapy. However, at 2 and 3 years following treatment, survival benefits are less clear. Any survival benefits come at the expense of increased major and overall complications.

Is splenectomy for dissecting splenic hilar lymph nodes justified for scirrhous gastric cancer? Gastric Cancer 2020; 23:922-926. [PMID: 32211994 DOI: 10.1007/s10120-020-01063-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2019] [Accepted: 03/12/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Splenectomy for dissecting splenic hilar lymph nodes (#10) should be avoided for most gastric cancer, considering the high morbidity and lack of any survival benefit, but it is often selected for scirrhous gastric cancer because this type frequently invades the whole stomach and lymph nodes. Splenectomy is necessary for dissecting #10; however, the survival benefit of dissecting #10 is unclear. METHODS Patients who had scirrhous gastric cancer and underwent D2 total gastrectomy with splenectomy at National Cancer Center Hospital, Japan, between 2000 and 2011 were retrospectively analyzed. The therapeutic value index was calculated by multiplying the metastatic rate of each nodal station and the 5-year survival of patients who had metastasis to each node. RESULTS In total, 137 patients were eligible for the present study. The most frequent metastatic node was #3(58%), followed by #4d(46%), #1(35%), #4sb(23%), #6(22%), #7(21%), #4sa(18%), #10(15%), #2(14%), #11p(14%), #11d(13%), #9(13%), and #8a(11%). These lymph nodes had a metastatic rate of more than 10%. The node station with the highest index was #3(18.9), followed by #4d(14.1), #1(10.8), #4sa(6.11), #4sb(6.06), #10(5.09), #7(4.39), #11d(4.36), #11p(4.06), #2(2.93), #8a(2.18), and #9(1.45). The index of #10 exceeded that of #2, #7, #8a, and #9, which are the key nodes dissected in D2. CONCLUSION The metastatic rate of the splenic hilar lymph nodes was relatively high, and the therapeutic index was the sixth highest among the 15 regional lymph nodes included in D2 dissection. Splenectomy for dissecting splenic hilar lymph nodes would be justified for scirrhous gastric cancer.

Abstract
Gastric cancer (GC) is a leading cause of worldwide cancer-related death. Being a highly heterogeneous disease, the current treatment of GC has been suboptimal due to the lack of subtype-dependent therapies. Peritoneal dissemination (PD) is a common pattern of GC metastasis associated with poor prognosis. Therefore, it is urgently necessary to identify patients at high risk of PD. PD is found to be associated with Lauren diffuse type GC. Molecular profiling of GC, especially diffuse type GC, has been utilized to identify molecular alterations and has given rise to various molecular classifications, shedding light on the underlying mechanism of PD and enabling identification of patients at higher PD risk. In addition, a series of diagnositc and prognostic biomarkers of PD from serum, peritoneal lavages and primary GCs have been reported. This comprehensive review summarizes findings on the multi-omic characteristics of diffuse type GC, the clinical significance of updating molecular classifications of GC in association with PD risk and research advances in PD-associated biomarkers.

Abstract
OBJECTIVES The benefits of curative or palliative gastrectomy for Borrmann type IV (B-IV) gastric cancer remain controversial. This study was conducted to investigate whether or not gastrectomy could benefit prognosis of patients with Borrmann type IV gastric cancer. MATERIAL AND METHODS A cohort of 469 B-IV gastric cancer patients from January 2001 to September 2017 was retrospectively reviewed. Survival analysis was used to investigate the prognosis of patients with or without gastrectomy. RESULTS Among this cohort, the average age was 55 years and the median follow-up time was 12 months. One hundred and forty-six (31%) patients underwent curative resection, 187 (40%) patients underwent palliative resection, and the remaining 136 (29%) patients were judged unresectable. During the follow-up, a total of 294 (63%) patients died. Cox multivariate analysis showed that Tumor Node Metastasis (TNM) stage (p = 0.002), grade (p = 0.033), and gastrectomy (p < 0.001) were independent predictors of overall survival. Kaplan-Meier analysis revealed that, no matter in total group or subgroup stratified by tumor stage and grade, overall survival rates at 1 year, 2 years, and 5 years in patients with palliative resection were significantly worse than those in patients with curative resection (all p < 0.05), but significantly better than those in patients with no resection (all p < 0.05). CONCLUSIONS Curative or palliative gastrectomy could increase the survival rate for B-IV gastric cancer patients. In the absence of alternative effective therapies, surgical resection remains a choice of improved survival or potential cure for B-IV gastric cancer.

Abstract
BACKGROUND The prognosis of patients with linitis plastica (LP) gastric cancer is reported to be poor. The purpose of our retrospective study was to characterize the clinicopathologic features and survival outcomes of patients with LP, using a univocal definition. METHODS We defined LP as gastric cancer that involves more than 1/3 of the gastric wall macroscopically. We reviewed a prospectively maintained institutional database of gastric cancer patients and summarized and compared clinicopathologic factors of patients with and without LP who had undergone gastrectomy. Patients were matched 1:1 using propensity score matching, and their overall survival (OS) rates and durations were compared. Multivariable Cox regression analyses were conducted, using gastrectomy as a time-varying covariate. RESULTS We identified 740 patients with radiographically non-metastatic gastric cancer, 157 (21.2%) of whom had LP. Most patients with LP had advanced-stage disease (75.8% had stage IV disease, mainly due to peritoneal involvement). Patients with LP had significantly shorter OS durations than did those without LP in the entire cohort (median OS, 14.0 vs. 33.5 months; p value < 0.001) and in the surgical cohort (median OS after gastrectomy, 21.8 vs. 91.0 months; p < 0.001), as well as in the propensity-matched surgical cohort. In the LP cohort, chemotherapy (hazard ratio [HR] = 0.594; p = 0.076), chemoradiation therapy (HR = 0.346; p = 0.001), and gastrectomy (HR = 0.425; p = 0.003) were associated with a longer OS. CONCLUSIONS LP is a phenotype of gastric cancer that often presents at an advanced stage, with a high rate of peritoneal involvement. The survival durations of patients with LP were poor in our study, even in the surgical cohort. The use of preoperative chemotherapy, chemoradiation therapy, and gastrectomy appeared to be important in carefully selected patients with localized LP.

Abstract
Purpose This study evaluated the usefulness of semiquantitative and volumetric PET parameters for predicting prognosis in patients with advanced gastric cancer (AGC). Methods We enrolled 213 patients who underwent 18F-fluoro-2-deoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) prior to curative surgery for AGC. Maximum standardized uptake value (SUVmax) and tumor-to-liver uptake ratio (TLR) were measured in all patients. Metabolic tumor volume (MTV) and total lesion glycolysis were measured in volume-measurable patients. For further quantification of FDG uptake, we developed PET prognostic scores by combining SUVmax and MTV (1: low SUVmax/low MTV; 2: high SUVmax/low MTV; 3: high SUVmax/high MTV). Comparison of PET parameters between recurrence and non-recurrence groups was performed. Univariate and multivariate analyses for recurrence-free survival (RFS) and overall survival (OS) were subsequently performed. Results The recurrence rate was 32.4% (69/213 patients). Mean SUVmax and mean MTV of the recurrence group were significantly higher than those of the non-recurrence group (p = 0.026 and p = 0.025). TLR showed marginal significance (p = 0.051). In multivariate analysis for RFS including all patients, SUVmax (p = 0.022), TLR (p = 0.010), and PET score (p = 0.003) were independent prognostic factors. In post hoc analysis of PET score, significant differences in RFS were observed between PET scores 2 and 3 as well as scores 1 and 3. No significant difference in RFS was observed between scores 1 and 2. Only PET score was statistically significant for OS in univariate analysis. None of the PET parameters were statistically significant for OS in multivariate analysis. Conclusion High SUVmax and high MTV of the primary tumor suggest a high risk of recurrence for AGC patients. Even if SUVmax is similar, the prognosis may vary depending on MTV. Combining PET parameters results in a better prediction for prognosis.

Abstract
Gastric adenocarcinoma remains an aggressive and poorly understood malignancy with a heterogeneous presentation and tumor biology. The current histologic and anatomic classification has been ineffective in guiding therapy, with only marginal improvement in outcome over time. Furthermore, the variation in presentation and disease among racial and ethnic groups amplifies the complexity of this cancer. An understanding of the clinical and molecular variability is important for effective treatment. Recent advances in molecular biology have better defined gastric cancer subtypes. We systematically review recent literature on the molecular classification of gastric adenocarcinoma and the associated management implications, with an emphasis on Hispanic and Native American populations.

Abstract
BACKGROUND Gastric cancer is the fifth most prevalent and the third most lethal cancer worldwide, causing approximately 720,000 deaths annually. Although most cases of gastric cancers are sporadic, one of its inherited forms, hereditary diffuse gastric cancer (HDGC), constitutes about 1-3% of cases. Interestingly, females in families with HDGC are also predisposed to developing lobular breast cancer (LBC). Recent analyses have identified loss-of-function germline mutations in cadherein-1 (CDH1) as a culprit in HDGC and LBC. This discovery fueled several sequencing analyses and case series reports analyzing the pattern of inheritance of CDH1 and its propensity to induce HDGC. In 2015, a multinational and multidisciplinary task force updated the guidelines and criteria for screening, diagnosing, and managing HDGC. CASE PRESENTATION Here, we present a case series of three siblings with family history of HDGC who tested positive for the CDH1 mutation and describe their surgical treatment course, post-operative management, and follow-up as they pertain to the updated guidelines. CONCLUSIONS Despite recent updates in guidelines in the diagnosis and management of HDGC, the disease remains challenging to address with patients given the high level of uncertainty and the comorbidities associated with prophylactic intervention. We strongly recommend that an interdisciplinary team inclusive of clinical and surgical oncologists, along with geneticists, social work, and psychological support, should follow the patients in a longitudinal and comprehensive manner in order to achieve full recovery and return to normalcy, as with our patients.

Abstract
Background Gastric cancer (GC) is associated with poor survival despite curative-intent surgical resection and systemic therapy. Our objective is to examine the impact of histology on prognosis as well as the impact of linitis plastica (LP) on survival. Methods The GC database at a single institution was evaluated for patients who underwent resection from 2000 to 2015. Clinicopathologic characteristics were examined and descriptive statistics was used to analyze four groups of patients based on Lauren classification: intestinal (n=93), diffuse (n=20), diffuse with signet-ring cell features (n=57), and LP (n=40). LP patients had diffuse GC but also presented with circumferential infiltration of the gastric wall for at least a third of the stomach length on endoscopy or imaging. Fisher's exact test was used to compare groups; Cox regression was used for multivariate analysis and Kaplan-Meier method for survival. Results Of 210 patients who underwent gastric resection, 112 (53%) were male with mean age 65.3 years (SD ±14.6 years). Intestinal GC patients were older at diagnosis but other patient demographics were similar between all groups. LP patients had a higher rate of R1 resection despite higher rates of total gastrectomy (P<0.01). Rates of perineural invasion (PNI) and nodal metastasis were higher in LP (P<0.001). The majority of intestinal GC patients (79%) had stage I/II disease compared to 70% of LP patients with stage III disease. Median overall survival (OS) was 13.7 months for LP, 79 months for intestinal, 97 months for signet-ring cell, and not reached for diffuse GC (P<0.001). When stratified by stage, there were no significant differences in survival by histology for stage II and stage III patients. However, by Cox regression analysis, factors associated with worse survival included lymphovascular invasion (LVI), nodal disease, and presence of LP. Neutrophil-lymphocyte ratio (NLR), neoadjuvant and adjuvant therapy, and tumor regression grade did not influence survival on multivariate analysis. Conclusions Intestinal GC is thought to have a better prognosis. Interestingly, this study demonstrates similar outcomes in patients with intestinal, diffuse, and signet-ring cell GC. However, a subset of diffuse GC-LP was associated with an infiltrative pattern of disease characterized by PNI and LVI. Despite controlling for poor prognostic markers, LP was independently associated with a worse prognosis. More research is needed to identify methods of earlier diagnosis and effective systemic therapy to treat this aggressive disease.

Abstract
In this retrospective study, we analyzed prognostic factors associated with survival outcomes in 73 locally advanced gastric cancer patients treated with neoadjuvant chemotherapy (NAC) followed by surgical resection. Median disease-free survival (DFS) for 64 patients that received R0 resection was 685 days, whereas median overall survival (OS) for 73 patients was 930 days. Multivariate analysis demonstrated that post-treatment nodal stages (P = 0.002), nervous invasion (P = 0.0492) and serum CA199 levels (P = 0.0398) were independent prognostic factors for DFS. Nodal stages (P = 0.0007), presence of nervous invasion (P = 0.0259) and non-radical resection (P = 0.0165) were independent prognostic factors for OS. These results indicate that post-treatment nodal stages, neural invasion and serum CA199 levels are all associated with poor DFS. Moreover, post-treatment nodal stage, resection type and neural invasion status are independent prognostic factors for OS.

Abstract
Background Linitis plastica due to gastric adenocarcinoma is a condition with a long history, but still lacks a standardized definition and is commonly confused with Borrmann type IV, Lauren diffuse, and signet-cell type gastric cancer. The absence of a clear definition is a problem when investigating its biological characteristics and role as a possible independent factor for prognosis. Nevertheless, the biological behavior for linitis plastica, which is unique, may be valuable in risk stratification and have implications for treatment. A definition of linitis plastica based on molecular or genomic criteria could represent a useful starting point for investigating new targeted therapies. Main body This literature review of linitis plastica will focus on the current classifications for gastric cancer, illustrating how the concept of linitis plastica relates to them in most cases and identifying a clear and reproducible definition. Moreover, the review will highlight the diagnostic challenges associated with linitis plastica, its prognostic implications, and the therapeutic options available. Future perspectives for its management are also addressed. Conclusion Linitis plastica is a carcinoma with a scirrhous stroma, involving the submucosal and muscular layers of the stomach even in the absence of mucosal alteration. In most cases, the primary cancer cells are signet-ring cells or scattered cells in the context of a poorly differentiated carcinoma. Diagnosis is challenging. Staging should be thorough, including diagnostic laparoscopy in all cases due to the high incidence of peritoneal involvement. The prognostic significance of linitis plastica is still controversial. Curative-intent surgery, when feasible, should be performed, with a multimodality treatment approach. Cancer-stroma interactions are important features of this disease, and represent attaining potential target for future therapies. Future pathologic assessments of gastric cancer should report the stromal reaction in order to allow better characterization of the tumor.

Abstract
The purpose of this study was to evaluate the relationship between extracapsular lymph node spread (ECS) and clinicopathology and its influence on the prognosis in patients with Borrmann type IV gastric cancer. Between 2002 and 2014, clinical data were reviewed from 486 patients with Borrmann type IV gastric cancer who underwent curative resection. Of the 486 patients, lymph node metastasis was found in 456. ECS was detected in 213 (46.7%) patients with lymph node metastasis. A positive lymph node with ECS was significantly correlated with the N category, lymphatic/venous invasion, tumor location, and TNM stage. For the whole patients, the mean OS was 34.7 months, and the 5-year OS rate was 15.5%. The 5-year OS rate of node-negative patients was 48%, for node-positive patients without ECS 18.7%, and for node-positive patients with ECS 5.7% (P = 0.000). In a multivariate analysis, adjusted for tumor location, lymphatic/venous invasion, body mass index (BMI), and TNM stages, ECS remained an independent prognostic factor. For patients with the same N category and TNM stage, those with ECS still had a worse survival rate. Recurrent sites were confirmed in 367 patients. The most frequent recurrent site was the peritoneum. There was a significant difference between ECS+ (N = 150) and ECS- (N = 142) patients (P = 0.008). Our results suggested that ECS was an independent prognostic value for Borrmann type IV gastric cancer patients with curative resection and a subgroup indicated a significantly worse long-term survival for patients with the same N or TNM stages. ECS+ was an adverse factor for peritoneal metastasis.

Abstract
Collagen components in the tumor microenvironment substantially influence cancer pathogenesis and progression. Nevertheless, in gastric cancer, collagen status and its prognostic role remain unclear. Using picrosirius red staining and immunohistochemistry, we found that collagen deposition was significantly increased in gastric cancer when compared with non-neoplastic tissues, and in cancer stroma, more immature collagen components were present, suggesting a qualitative change. Furthermore, the morphology of collagen fibers could be weakly, moderately or strongly changed in gastric cancer; when weakly or moderately changed, they appeared similar to normal collagen fibers, except for a higher linearization and density; when strongly changed, they were thicker and less eosinophilic, sharply differently from their normal counterparts. In addition, we found abundant myofibroblasts and elevated expression of lysyl oxidase-like 2 (the enzyme that mediates crosslinking of collagen molecules) in cancer stroma, which might contribute to the increased collagen deposition and crosslinking. Last, five collagen architectural parameters (alignment, density, width, length and straightness) were analyzed with second harmonic generation imaging, a highly specific technology for detection of collagen fibers, and our data indicated that all the parameters were significantly increased in the tumor microenvironment. Of the five parameters, collagen width was the most powerful parameter in predicting 5-year overall survival, and increased collagen width was associated with reduced survival. The prognostic value of collagen width was superior to traditional clinicopathological parameters, and this was validated in two unrelated gastric cancer cohorts that contained 225 and 151 patients. Collectively, the collagen status (content, maturity, morphology and architecture) was profoundly reorganized in the tumor microenvironment of gastric cancer, and collagen width could serve as a valuable prognostic indicator.

Abstract
PURPOSE To evaluate the enhancement pattern of diffuse-type gastric cancers (DGCs) on multiphasic contrast-enhanced computed tomography gastrography (CECTG). METHODS AND MATERIALS We studied 21 consecutive clinically diagnosed DGC patients who underwent CECTG. Gastric distension was obtained using effervescent granules. CT images were obtained 40 s (arterial phase) and 240 s (delayed phase) after injection of a nonionic contrast material. Two radiologists reviewed the CT images and analyzed layers and enhancement patterns. The readers evaluated the enhancement degree (mild, moderate, or marked) and calculated CT attenuation values by placing circular regions of interest (ROIs) within each layer of the lesion. The CT findings of 11 operated cases were correlated with pathological results. RESULTS Most lesions were double-layered in the arterial phase, with a moderately enhanced inner layer and a mildly enhanced outer layer, and single-layered in the delayed phase. The mean attenuation value of the inner layer (146 ± 32.8 HU) was significantly higher than that of the outer layer (80.4 ± 15.5 HU) in the arterial phase (p = 0.0001). In the pathological analysis, wall stratification was preserved in nine cases and not preserved in two cases. CONCLUSION Most DGCs showed a double-layered pattern in the arterial phase and a single-layered pattern with moderate enhancement in the delayed phase.

Abstract
INTRODUCTION Linitis plastica (LP) is a particular subtype of diffuse gastric cancer and is thought to have a very poor prognosis. The operative approach in patients with LP has historically been questioned because of the poor outcomes. The aim of this study was to determine the current outcomes in LP patients who undergo radical resection. METHODS Patients with a new diagnosis of diffuse gastric adenocarcinoma between 2006 and 2010 were identified from a regional pathology database. LP was diagnosed based on histological, radiological and endoscopic findings. The patients' health records were analysed retrospectively and mortality data obtained from a regional cancer registry. The primary outcome assessed was overall survival. RESULTS Overall, 273 patients with diffuse gastric cancer were identified; 54 of these were diagnosed with LP. In the LP cohort, 17 patients underwent resection compared with 95 of the 219 patients in the non-LP group. The median survival following resection in patients with LP was 16.7 months (95% confidence interval [CI]: 8.3-25.1) while in LP patients who did not have surgery it was 3.6 months (95% CI: 2.2-4.9 months) (p<0.001). There was no significant difference in survival following resection between those with LP and those with non-LP diffuse gastric adenocarcinoma (median: 23.9 months, 95% CI: 15.8-32.1 months) (p=0.331). CONCLUSIONS Survival following resection in patients with LP is not significantly different to that in those with non-LP diffuse gastric cancer. A preoperative diagnosis of LP should not be a reason for denying radical treatment and such individuals should be managed in the same way as any other patient with diffuse gastric cancer.

Abstract
Linitis plastica (LP), a subset of gastric adenocarcinoma (GA), has been considered as a fatal disease with few management options. Little evidence has been reported regarding the role for surgical therapy in treating LP. A retrospective review of GA patients with LP from the surveillance, epidemiology, and end results database (2004–2009) was performed. 29,440 patients with GA were identified, of whom 948 (3.2%) had LP. After matching for American Joint Commission on Cancer (AJCC) stage, LP patients had significantly worse 5-year disease specific survival (DSS) compared with GA (6 vs 34%, P < 0.001). For potentially resectable LP patients (i.e., stage I–III), 5-year DSS was 0 per cent for no treatment and for radiation therapy alone, 18 per cent for both and surgery and radiation, and 20 per cent for surgery alone(P < 0.001). LP is a marker of poor survival in patients with GA. However, surgical resection provides the best oncologic outcomes in these patients with a 20 per cent 5-year DSS in patients with loco-regional disease.

"Linitis plastica" was defined based on histological characteristics. Primary and secondary linitis plastica were included. Two readers independently assessed the radiological findings (i.e., number of lesions, mass, wall thickening, and enhancement). RESULTS The patient cohort comprised 23 men and 22 women with an average age of 63.2 years. The main presenting signs and symptoms were impaired general health and ascites (22/45 patients, 48.8%). The stomach was the affected organ in 68.3% of the cases, while the rectum was affected in 11.7% of the cases. Primary linitis was found in 73.3% of the cases, and solitary lesions were found in 77.8% of the cases. The most common CT finding was wall thickening (91.7%) with a complete disappearance of folds and enhancement of the entire wall at 2 min. Four lesions (6.6%) were described as masses, and only one (1.7%) was described as a wall atrophy. CONCLUSION Linitis plastica can affect the entire digestive system. Its potentially secondary nature necessitates a systematic search for a primary tumor. An appropriate CT protocol is required to detect the specific radiological features of this fibrous cancer. CT can help confirm the diagnosis of linitis plastica, rule out differential diagnoses, and indicate the need for deep biopsies where possible.

Limited significance of curative surgery in Borrmann type IV gastric cancer. Med Oncol 2016; 33:69. [PMID: 27251378 DOI: 10.1007/s12032-016-0783-3] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2016] [Accepted: 05/22/2016] [Indexed: 12/23/2022]
Abstract
Borrmann type IV advanced gastric cancer has a poor prognosis. Although surgical resection remains the only hope for a cure, the role of curative surgery is questionable in this type of cancer. This study defined the role of curative surgery in the prognosis of type IV gastric cancer. We analyzed 168 patients with Borrmann type IV undergoing surgery at Seoul St. Mary's Hospital from 1989 to 2010. We categorized the patients into curative (R0) and non-curative (R1, R2, and non-resection) groups. The curative and non-curative groups comprised 88 and 80 patients, respectively. The preoperative predictive value of Borrmann type IV was 50.5, and 8.9 % of the patients had microscopic resection margin involvement. The 3- to 5-year overall survival (OS) of patients in the curative group was significantly higher than that of in the non-curative group (p < 0.001). However, in a multivariate analysis, curability was not a significant predictor of survival (p = 0.187). In the curative group, the most frequent recurrence site was the peritoneum (85.7 %). Most recurrences occurred within 2 years. The role of surgery for Borrmann type IV is quite limited. Such cases have a poor prognosis even after curative surgery. In addition, microscopic resection margin involvement is frequent in type IV cancer because it is difficult to diagnose preoperatively. Therefore, multimodal diagnostic tools and treatment strategies should be developed for Borrmann type IV gastric cancer.

Abstract
BACKGROUND Current staging and treatment guidelines for gastric adenocarcinoma do not differentiate between linitis plastic (LP) and non-LP cancers. Significant controversy exists regarding the surgical management of LP patients. METHODS Using the multi-institutional U.S. Gastric Cancer Collaborative database, 869 gastric cancer patients who underwent resection between 2000 and 2012 were identified. Clinicopathologic and outcomes data of 58 LP patients were compared to 811 non-LP patients. RESULTS Stage III/IV disease was more common at presentation in LP patients compared with non-LP patients (90 vs. 44 %, p < 0.01). Despite the fact that most LP patients underwent total gastrectomy (88 vs. 39 %, p < 0.01), final positive margins were more common in LP patients (33 vs. 7 %, p < 0.01). The use of frozen section allowed 15 intraoperative positive margins in 38 patients to be converted to negative final margins. Median overall survival (OS) was significantly worse in patients with LP (11.6 vs. 37.8 months, p < 0.01). There was no difference in median OS of LP patients based on stage (I/II, 17.3 mo; III, 10.6 mo; IV, 12.0 mo; p = 0.46). LP and non-LP patients who underwent optimal resection (negative margin and D2/3 lymphadenectomy) had better survival compared with those with nonoptimal resections. The median OS for optimally resected stage III LP (n = 22) and stage III non-LP (n = 185) patients was nearly identical (26.7 vs. 25.3 mo; p = 0.69). CONCLUSIONS Future staging systems and treatment guidelines should differentiate between LP and non-LP gastric cancers. Long-term survival in select LP patients who undergo optimal resections is comparable to optimally resected non-LP patients.

Clinicopathologic and Prognostic Value of Serum Carbohydrate Antigen 19-9 in Gastric Cancer: A Meta-Analysis. DISEASE MARKERS 2015; 2015:549843. [PMID: 26576068 PMCID: PMC4631884 DOI: 10.1155/2015/549843] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/20/2015] [Accepted: 09/29/2015] [Indexed: 12/12/2022]
Abstract
Background. The clinical value of carbohydrate antigen (CA) 19-9 in gastric cancer is controversial. We evaluated the clinicopathologic and prognostic value of CA 19-9 in gastric cancer. Methods. A literature search was conducted in PubMed and Embase databases. Odds ratios (ORs), risk ratios (RR), hazard ratios (HRs), and 95% confidence intervals (CIs) were used as effect measures. Results. Thirty-eight studies were included. Results showed that there were significant differences in the incidence of high CA 19-9 levels between stages III/IV and I/II groups (OR = 3.36; 95% CI = 2.34–4.84), the pT3/T4 and pT1/T2 groups (OR = 2.40; 95% CI = 1.60–3.59), the lymph node-positive and node-negative groups (OR = 2.91; 95% CI = 2.21–3.84), the metastasis-positive and metastasis-negative groups (OR = 2.76; 95% CI = 1.12–6.82), and vessel invasion-positive and invasion-negative groups (OR = 1.66; 95% CI = 1.11–2.48). Moreover, CA 19-9 was significantly associated with poor overall survival (HR = 1.83; 95% CI = 1.56–2.15), disease-free survival (HR = 1.85; 95% CI = 1.16–2.95), and disease-specific survival (HR = 1.33; 95% CI = 1.10–1.60) in gastric cancer. Conclusions. Our meta-analysis showed that CA 19-9 indicates clinicopathologic characteristics of gastric cancer and is associated with a poor prognosis.

Abstract
Scirrhous gastric cancer is frequently associated with peritoneal dissemination, and the interaction of cancer cells with peritoneal mesothelial cells (PMCs) is crucial for the establishment of the metastasis in the peritoneum. Although cells derived from PMCs are detected within tumors of peritoneal carcinomatosis, how PMCs are incorporated into tumor architecture is not understood. The present study shows that PMCs create the invasion front of peritoneal carcinomatosis, which depends on activation of Tks5 in PMCs. In peritoneal tumor implants, PMCs represent majority of cells located at the invasive edge of the cancer tissue. Exogenously implanted PMCs and host PMCs aggressively invade into abdominal wall upon the peritoneal inoculation of cancer cells, and PMCs locate ahead of cancer cells in the direction of invasion. Tks5, a substrate of Src kinase, is predominantly expressed in the PMCs of cancer tissue, and promotes the invasion of PMCs and cancer cells. Expression and activation of Tks5 was induced in PMCs following their exposure to gastric cancer cells, and increased Tks5 expression was detected in PMCs located at the invasion front. Reduced Tks5 expression in PMCs blocked PMC invasion, which in turn prevents cancer cell invasion both in vitro and in vivo. The peritoneal dissemination of gastric cancer was significantly increased by mixing cancer cells and PMCs, and was suppressed by knockdown of Tks5 in PMCs. These results suggest that cancer-activated PMCs create invasion front by guiding cancer cells. Signaling leading to Tks5 activation in PMCs may be a suitable therapeutic target for prevention of peritoneal carcinomatosis.

Abstract
OBJECTIVE Defining processes of care, which are appropriate and necessary for management of gastric cancer (GC), is an important step toward improving outcomes. METHODS Using a RAND/UCLA Appropriateness Method, an international multidisciplinary expert panel created 22 statements reflecting optimal management. All statements were scored for appropriateness and necessity. RESULTS The following tenets were scored appropriate and necessary: (1) preoperative staging by computed tomography of abdomen/pelvis; (2) positron-emission tomographic scans not routinely indicated; (3) consideration for adjuvant therapy; (4) further clinical trials; (5) multidisciplinary decision making; (6) sufficient support at hospitals; (7) assessment of 16 or more lymph nodes (LNs); (8) in metastatic disease, surgery only for palliation of major symptoms; (9) surgeons experienced in GC management; (10) and surgeons experienced in both GC management and advanced laparoscopic surgery for laparoscopic resection. The following were scored appropriate, but of indeterminate necessity: (1) diagnostic laparoscopy before treatment; (2) a multidisciplinary approach to linitis plastica; (3) genetic assessment for diffuse GC and family history, or age less than 45 years; (4) endoscopic removal of select T1aN0 lesions; (5) D2 LN dissection in curative intent cases; (6) D1 LN dissection for early GC or patients with comorbidities; (7) frozen section analysis of margins; (8) nonemergent cases performed in a hospital with a volume of more than 15 resections per year; and (9) by a surgeon with more than 6 resection per year. CONCLUSIONS The expert panel has created 22 statements for the perioperative management of GC patients, to provide guidance to clinicians and improve the care received by patients.

Abstract
BACKGROUND To obtain the maximum additional information about the prognosis of gastric cancer, we compared CA-50 with other previously defined markers. MATERIALS AND METHODS This hospital based study was carried out in the Department of Biochemistry of Nepalese Army Institute of Health Sciences between 1st July 2012 and 31st December 2012. The variables collected were age, gender, AFP, CEA, CA19-9, and CA50, assayed with ELISA reader for all cases. The cut off values for serum AFP, CEA, CA19-9, and CA-50 were 10 μg/l, 10 μg/l, 37 U/ml, and 20 U/ml, respectively according to the manufacturer's instructions. Approval for the study was obtained from the institutional research ethical committee. RESULTS Of the 40 examined patients, 13 patients had tumors located in the upper third of the stomach, 6 patients had tumors in the middle third, 16 patients had tumors in the lower third, and 5 patients had tumors occupying two-thirds of the stomach or more. The distribution of lymph node staging of the patients was as follows: 7 patients belonged to N0, 9 patients to N1 stage, 10 patients to N2 stage, and 14 patients to N3 stage. The statistical method of Cox proportional hazards using multivariate analysis also illustrated that tumor markers including CEA (2.802), CA19-9 (2.690), CA50 (2.101), were independent prognostic factors, as tumor size (1.603), and lymph node stage (1.614). CONCLUSIONS The tumour markers now available, like CEA, CA 19-9 and CA 50, chiefly perceive advanced gastric cancer. The preoperative rise in those tumour marker level have a prognostic significance and may be clinically helpful in choosing patients for adjuvant management.

Abstract
Gastric linitis plastica is a diffuse type of cancer which is characterised by a thickening and rigidity of the stomach wall. It is notorious for its failure to cause early symptoms, and patients with symptoms generally have a more advanced form of the disease. We report our 18-month-long experience of managing gastric linitis plastica at Barnsley District General Hospital, UK. In our series of 8 patients, only one patient was offered surgery; the rest were offered palliative or supportive treatment. The findings in our series were consistent with the available evidence that curative treatment is not an option for the majority of cases with linitis plastica.

Abstract
AIM To study the outcome of patients who were surgically treated for primary gastric cancer with specific attention to differences in treatment results for intestinal and diffuse type tumours. METHODS All patients who underwent a potentially curative gastric resection between 1995 and 2011 in our institute were included. Patient, tumour and treatment characteristics were obtained retrospectively. Binary logistic and Cox regression models were used for multivariate analysis. RESULTS A consecutive series of 132 patients was included. Median follow-up was 53 months. There were no significant differences between patients with intestinal (N = 62) versus diffuse type (N = 70) gastric cancer with regard to the proportion of patients who underwent (neo)adjuvant treatment. Postoperative mortality was 2%. Pathological T- and N-stage were significantly more advanced for patients with diffuse type tumours. There was a significant difference in the percentage of microscopically irradical resections (2% versus 24%, p < 0.001) and median overall survival (129 versus 17 months, p < 0.001) between patients with intestinal type tumours and those with diffuse type tumours. On multivariate analysis, diffuse type histology was the only factor significantly associated with an R1 resection. In a multivariate Cox regression model, diffuse type histology was a significant adverse prognostic factor for overall survival. CONCLUSIONS Striking differences were found between patients with diffuse type tumours and those with intestinal type tumours. These differences call for a differentiated approach in the potentially curative treatment of these two tumour types.

Abstract
Patients with ESCC (squamous cell carcinoma of the esophagus) are most commonly diagnosed with locally advanced tumor stages. Early metastatic disease and late diagnosis are common reasons responsible for this tumor's poor clinical outcome. The prognosis of esophageal cancer is very poor because patients usually do not have symptoms in early disease stages. Squamous cell carcinoma of the esophagus frequently complicates patients with multiple co-morbidities and these patients often require interdisciplinary diagnosis and treatment procedures. At present time, neoadjuvant radiation therapy and chemotherapy followed by surgery are regarded as the international standard of care. Meta-analyses have confirmed that this approach provides the patient with better local tumor control and an increased overall survival rate. It is recommended that patients with positive tumor response to neoadjuvant therapy and who are poor surgical candidates should consider definitive radiochemotherapy without surgery as a treatment option. In future, EGFR antibodies may also be administered to patients during therapy to improve the current treatment effectiveness. Positron-emission tomography proves to be an early response-imaging tool used to evaluate the effect of the neoadjuvant therapy and could be used as a predictive factor for the survival rate in ESCC. The percentage proportions of residual tumor cells in the histopathological analyses represent a gold standard for evaluating the response rate to radiochemotherapy. In the future, early response evaluation and molecular biological tests could be important diagnostic tools in influencing the treatment decisions of ESCC patients.
