BACKGROUND: Metastatic choroidal carcinomas that originated from the gastrointestinal tract are extremely rare. We report a case of suspected solitary choroidal metastasis from gastric adenocarcinoma. CASE PRESENTATION: The patient was a 60-year-old man who had undergone laparoscopic distal gastrectomy with D1+ lymphadenecetomy for gastric cancer. The clinical stage was T1bN0M0 (TNM classification), but the pathological stage was T4aN0M0 beyond expectation. Adjuvant chemotherapy with oral Tegafur, Gimeracil, Oteracil potassium (TS-1(®)) was initiated...

The successful use of immune cell checkpoint inhibitors PD-1 and PD-L1, over the past 5 y has raised the concern of using immunotherapy to treat various cancers. Epstein-Barr virus-associated gastric cancer (EBVaGC) exhibits high infiltration of lymphocytes and high amplification of immune-related genes including PD-L1 as distinguished from Epstein-Barr virus-non-associated gastric cancer (EBVnGC). Here, we presume that this PD-1/PD-L1 pathway may hinder the efficacy of adoptive T cell therapy toward EBVaGC...

ETHNOPHARMACOLOGICAL RELEVANCE: Many patients with gastric cancer seek traditional medicine consultations in Asian countries. This study aimed to investigate the prescription of Chinese herbal medicine (CHM) and its benefits for the patients with gastric cancer in Taiwan. METHODS: From the Registry for Catastrophic Illness Patients Database, we included all patients with gastric cancer whose age at diagnosis was ≥ 18 from 1997-2010 in Taiwan. We used 1:1 frequency matching by age, sex, Charlson comorbidity score, treatment and index year to compare the CHM users and non-CHM users...

Negative lymph node (NLN) count provides accurate prognostic information in patients with gastric cancer. However, it is unclear whether NLN still has prognostic value for patients received preoperative radiotherapy. In this study, Surveillance, Epidemiology, and End Results Program (SEER)-registered gastric cancer patients were used for analysis. Clinicopathological characteristics and survival time were collected. Univariate and multivariate Cox proportional hazards models were used to assess the risk factors for survival...

We report a case of advanced gastric cancer(AGC)that was resected for rebleeding after palliative radiotherapy for hemostasis. A 74-year-old man with Stage IV gastric cancer received chemotherapy and achieved stable disease. After 23 months, he experienced continuous bleeding from the tumor due to regrowth. Palliative radiotherapy was conducted to control the bleeding, and the tumor successfully achieved hemostasis. However, 6 weeks later, the patient experienced rebleeding and developed hemostatic shock. We then performed a successful emergency gastrectomy...

Case 1: An 71-year-old man underwent chemotherapy with S-1 plus trastuzumab to treat type 3 gastric cancer that was diagnosed as Stage IV tubular adenocarcinoma(T4b[Panc], N3, H0, CY1, P0, M1). For anemia and active bleeding from the tumor, transcatheter arterial embolization(TAE)was performed with metallic coils on the splenic artery. Infarction of the spleen and left pleural effusion were observed. Second-line paclitaxel(PTX)chemotherapy was administered 4 weeks after TAE. Case 2: An 76-year-old man underwent chemotherapy with S-1 plus cisplatin to treat type 3 gastric cancer that was diagnosed as Stage IV tubular adenocarcinoma(T4a, N3, H0, P1, M1)...

The patient was a 65-year-old woman. She was diagnosed with advanced gastric cancer with liver invasion. After receiving systemic chemotherapy(S-1 plus PTX)for 3 months, she underwent total gastrectomy and partial hepatectomy in May 2008. Because she developed celiac artery circumference lymph node recurrence in November 2010 during postoperative adjuvant chemotherapy consisting of S-1 plus PTX, we changed her chemotherapy regimen to CPT-11 plus CDDP. We observed an increase in the size of the lymph nodes in August 2013 and the response was poor even after switching to DOC...

BACKGROUND: While it is well established that the cell-mediated immune response plays an important role in cancer progression and spread, the role of the humoral immune response in this regard has been less studied. According to the existing literature, dense infiltration of B cells or plasma cells appears to correlate mainly with an improved prognosis in several types of cancer, but their prognostic impact in oesophageal and gastric cancer has not yet been described. METHODS: Immunohistochemistry was applied on tissue microarrays (TMA) to assess the stromal density of B cells (CD20+) and plasma cells [CD138+ or immunoglobulin kappa C (IGKC+)] in chemo-/radiotherapy-naive tumours from a consecutive cohort of 174 patients with resected oesophageal or gastric adenocarcinoma...

PURPOSE: Radiotherapy for gastric and gastroesophageal junction (GEJ) tumors commonly requires large margins due to deformation, motion and variable changes of the stomach anatomy, at the risk of increased normal tissue toxicities. This work quantifies the interfraction variation of stomach deformation from daily MRI-guided radiotherapy to allow for a more targeted determination of margin expansion in the treatment of gastric and GEJ tumors. METHODS: Five patients treated for gastric (n=3) and gastroesophageal junction (n=2) cancers with conventionally fractionated radiotherapy underwent daily MR imaging on a clinical MR-IGRT system...

OBJECTIVE: Esophageal resection is a traumatic intervention usually performed on patients with poor condition, resulting high mortality and morbidity. To improve the high incidence of complications, minimal invasive interventions were introduced. The results of the thoracoscopically and laparoscopically performed esophageal resection (McKeown) was investigated after 20 cases and the technical details of the surgical intervention are presented. PATIENTS AND METHOD: 20 thoracoscopic esophageal resection with laparoscopic gastric tube formation (sec...

BACKGROUND: In a large number of patients with multiple gastrointestinal adenomatous polyps, no causal germline mutation can be found. Non-genetic factors may contribute to the development of adenomatous polyps in these unexplained polyposis patients. In the development of gastrointestinal cancer, prior exposure to abdominal radiotherapy has been identified as such a factor, as it increases the gastrointestinal cancer risk in cancer survivors. A relationship of radiotherapy with intestinal polyposis, however, has not yet been described...

Gastric cancer (GC) is the third leading cause of cancer death in both sexes worldwide, with the highest estimated mortality rates in Eastern Asia and the lowest in Northern America. However, the availability of modern treatment has improved the survival and the prognosis is often poor due to biological characteristics of the disease. In oncology, we are living in the "Era" of target treatment and, to know biological aspects, prognostic factors and predictive response informations to therapy in GC is mandatory to apply the best strategy of treatment...

The World Health Organization (WHO) classification from 2014 differentiates between different subtypes of mucinous adenocarcinoma of the uterine cervix. A gastric subtype was recently described that showed no association with high-risk human papillomavirus (HPV) infections, has a poor prognosis, is mainly diagnosed in women of Asian origin and can occur in patients with Peutz-Jeghers syndrome. Although no clear grading system has been recommended in the WHO classification, it is likely that grading of adenocarcinomas of the uterine cervix will partly be based on the different patterns of invasion...

Although local advanced gastric cancer (AGC) could benefit from neoadjuvant radiotherapy (NRT), there are few studies evaluating patients' survival after NRT. In current study, we aimed to investigate the value of prognostic factors in AGC patients after NRT and to evaluate whether post-therapy pathological characteristics were predictive factors in these patients. We retrospectively analyzed AGC patients who underwent NRT from Surveillance, Epidemiology, and End Results (SEER) Database. The patients' clinical and post-therapy pathological characteristics were analyzed...

The prognosis for patients with upper gastrointestinal cancers remains dismal despite the development of multimodality therapies that incorporate surgery, chemotherapy, and radiotherapy. Early diagnosis and personalized treatment should lead to better prognosis. Given the advances in proteomic technologies over the past decades, proteomics promises to be the most effective technique to identify novel diagnostics and therapeutic targets. Areas covered: For this review, keywords were searched in combination with "proteomics" and "gastric cancer" or "esophageal cancer" in PubMed...
