Krukenberg tumours are rare metastatic tumours of the ovaries characterized by the presence of mucin-producing neoplastic Signet Ring Cell Carcinoma (SRCC). At first glance, this tumour may be confused with a primary ovarian tumour. Surgery and chemotherapy combination have led to improvement in prognosis, but it still remains severe. We report the case of a 60-year-old woman with a Krukenberg tumour rising from a low differentiated gastric adenocarcinoma. The patient was clinically stable for 26 months after surgery until she experienced a prompt decline and died of cerebral haemorrhage within two weeks...

BACKGROUND: Bariatric surgery has increased in popularity, with Roux-en-Y Gastric Bypass (RYGB) being one of the most frequently performed. This leads to many cases in which the stomach is removed from routine gastroscopy access, sometimes being a major source of concern. Performing enteroscopy in these patients is technically difficult. We present our experience with 24 cases in which the aim was to access the detached stomach. METHODS: Retrospective analysis on RYGB enteroscopy procedures aimed to access the detached stomach...

Treatment algorithm has not been established for early gastric cancer with signet ring cell carcinoma (SRC), which has a reported low rate of lymph node metastasis (LNM) similar to differentiated cancer. A cohort of 256 patients with early gastric SRC at our center between January 2002 and December 2015 were retrospectively reviewed. Multivariate logistic regression analysis was used to determine the independent factors of LNM. A nomogram for predicting LNM was constructed and internally validated. Additional external validation was performed using the database from Cancer Institute Ariake Hospital in Tokyo (n = 1273)...

OBJECTIVE: The aim of this study was to evaluate the prognostic significance of the intratumor stromal proportion in gastric signet ring cell (SRC) carcinomas. BACKGROUND: Cancer stroma, as exemplified by cancer-associated fibroblasts (CAFs), plays critical roles in cancer proliferation, invasion, and metastasis. METHODS: One hundred seventy-five SRC carcinoma cases were classified according to the intratumor desmoplastic stromal proportion to then analyze the clinicopathologic characteristics of stroma-rich cases...

Generalized high bone mineral density (BMD) on Dual-energy X-ray absorptiometry (DXA) scanning most commonly reflects metabolic bone disease. However, some malignancies could also stimulate the underlying processes. We reported that a 41-year-old female was referred for lumbago. She did not complain of any symptoms in the digestive system. DXA revealed high BMD in the lumbar vertebras. Marked increase in bone mass was observed in an X-ray of chest compared with one conducted 6 months previously. Additionally, an X-ray of the axial skeleton showed diffuse sclerotic change...

BACKGROUND: Gene expression profiling has contributed greatly to cancer research. However, expression-driven biomarker discovery in metastatic gastric cancer (mGC) remains unclear. A gene expression profile predicting RAD001 response in refractory GC was explored in this study. METHODS: Total RNA isolated from 54 tumour specimens from patients with mGC, prior to RAD001 treatment, was analysed via the NanoString nCounter gene expression assay. This assay targeted 477 genes representing 10 different GC-related oncogenic signalling and molecular subtype-specific expression signatures...

The incidence of Helicobacter pylori-negative gastric cancer (HpNGC) is extremely low. A 78-year old female without H. pylori infection was diagnosed with type 4 advanced-stage gastric prepylorus cancer. Distal gastrectomy was performed as for HpNGC (cT3N0M0). Histological findings of the resected specimen showed poorly differentiated adenocarcinoma and signet ring cell carcinoma, which were located in the pyloric gland area, diffusely invaded beyond the serosa without lymph node metastasis (pT4aN0M0). Most cases of undifferentiated-type HpNGC are diagnosed in the early stage and are located in the fundic gland area...

It has been shown that metastases to the thyroid from extrathyroidal malignancies occur as solitary or multiple nodules, or may involve the whole thyroid gland diffusely. However, diffuse metastasis of gastric cancer to the thyroid is extremely rare. Here, we report a case of a 74-year-old woman with diffuse infiltration of gastric adenocarcinoma (signet-ring-cell carcinoma/poorly differentiated adenocarcinoma) cells in the thyroid. The pathological diagnosis was made based on upper gastrointestinal endoscopy with biopsy and fine-needle aspiration cytology of the thyroid...

PURPOSE: Germline mutations in several genes confer a relevant lifetime risk of gastric cancer. In this context, an increasing involvement of a surgeon can be seen, mainly with the question of performing a prophylactic operation. METHODS: Patients with hereditary tumor syndromes predisposing for gastric cancer who received care leading to prophylactic total gastrectomy in our Center for Hereditary Tumor Syndromes were analyzed. For each patient, the multidisciplinary decision-making process, the perioperative course, and the histopathologic findings were assessed...

Adenocarcinomas are the most common cancers affecting stomach. However gastrointestinal stromal tumors (GIST), lymphomas and neuroendocrine tumors (NETs) can also affect the stomach. But stomach is relatively rare site of involvement by metastasis. In this case report a rare metastasis of germ cell tumor (GCT) into stomach is described which clinically and endoscopically masquerade as primary gastric cancers. But detailed clinical examination and vigilant histopathological reporting proves the origin of tumor distant from stomach and thereby change the whole approach of management...

BACKGROUND: The prediction of biologic behavior of poorly cohesive early gastric carcinoma (EGC) is an important issue in the selection of the treatment modality. To elucidate the risk factors for lymph node metastasis (LNM) of poorly cohesive EGC, we focused on the histologic purity of the poorly cohesive component and evaluated the impact of this factor on LNM. METHODS: We divided poorly cohesive EGC into (1) pure signet ring cell (SRC) carcinoma, which was defined as composed only of signet ring cells or poorly cohesive cells and (2) mixed SRC carcinoma, defined as poorly cohesive carcinoma with minor tubular components...
