Background This study evaluated the prognostic value of alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) together with host-related factors in patients with unresectable advanced gastric cancer. Methods The study enrolled 262 patients who received chemotherapy for unresectable advanced gastric cancer at Kochi Medical School from 2007 to 2015. Clinicopathological information and systemic inflammatory response data were analyzed for associations between baseline cancer-related prognostic variables and survival outcomes. Results The median survival time was significantly lower for patients with high ALP, high LDH, high total bilirubin, high aspartate aminotransferase, high alanine transaminase, high gamma-glutamyltransferase, high creatinine, a Glasgow prognostic score (GPS) of 1 or 2 score compared to GPS 0, higher compared to lower neutrophil to lymphocyte ratio (NLR) 3.9, lower compared to higher prognostic nutrition index 36.1, T3-4 compared to T1-2 tumor and diffuse-type compared to intestinaltype histology. Multivariate survival analysis identified high ALP 322 (HR 1.808; 95% CI 1.015-3.220; P = 0.044), T2-3 (HR 2.622; 95% CI 1.224-5.618; P = 0.013), and diffuse-type gastric cancer (HR 2.325; 95% CI 1.341-4.032; P = 0.003) as significant independent predictors of worse prognosis in the studied group of cancer patients. Conclusions High level of ALP is an independent, worse prognosis factor for patients receiving chemotherapy for unresectable and recurrent gastric cancer.
Intraoperative ICG assessment of the gastric tube was associated with PEA grading on anastomosis during esophagectomy.
Glomus tumor of the stomach is a rare submucosal mesenchymal tumor. The present study reports a patient with gastric glomus tumor treated by laparoscopic distal gastrectomy. A 39-year-old male was referred to Kochi Medical School Hospital for examination of a gastric submucosal tumor (SMT) initially diagnosed following a medical checkup. Esophagogastroduodenoscopy revealed a solitary, well-defined, submucosal lesion in the antrum of the stomach. Endoscopic ultrasonography (EUS) revealed a hypoechoic solid mass primarily connected to the gastric muscular layer. Abdominal contrast-enhanced computed tomography confirmed a 1.5 cm, well-defined mass lesion demonstrating homogeneous strong enhancement in the gastric antrum. Subsequent EUS-guided fine-needle aspiration produced a clinical diagnosis of neuroendocrine neoplasm and the patient underwent laparoscopic distal gastrectomy with regional lymph node dissection. Histopathology revealed solid proliferation of round, α-smooth muscle actin-immunopositive tumor cells with dilated vessels lined by endothelial cells without atypia, prompting a diagnosis of gastric glomus tumor. To the best of our knowledge, this is the seventh case of gastric glomus tumor treated by laparoscopy reported in English literature. The present case suggested that glomus tumor should be considered in the differential diagnosis for SMT of the stomach.
Background Spontaneous mesenteric hematoma (SMH) is a rare condition characterized by intraperitoneal hemorrhage of unknown etiology. SMH without worsening of general status allows conservative management; however, patients showing chronological changes on imaging require surgical intervention to rule out possible malignancy. Case presentation A 69-year-old man was referred to our hospital to evaluate an abdominal mass with no associated clinical symptoms. He had a history of chronic hepatitis C and diabetes mellitus. Six months earlier, computed tomography (CT) revealed a 75-mm tumor arising from the jejunum, suspected to be a gastrointestinal stromal tumor (GIST) of the small intestine. Following a further 6 months of observation, the patient was referred to our hospital. Abdominal contrast-enhanced CT revealed a well-defined heterogeneous round tumor with a maximum diameter of 75 mm adjacent to the upper jejunum. The tumor was accompanied by calcification at the periphery, with no evidence of augmentation over the prior 6 months. Diffuse lymphadenopathy was observed around the aorta and splenic artery. Under the diagnosis of GIST arising from small intestine, the patient underwent elective surgery. The resection revealed an elastic soft tumor at the mesentery adjacent to the upper jejunum with severe adhesion between the tumor and jejunum. The tumor origin was unclear; thus, we performed mesenteric excision and partial enterectomy without lymph node dissection. The tumor was surrounded by fibrous capsular tissue containing massive hemosiderin deposits and cholesterol crystals showing partial calcification, resulting in a diagnosis of spontaneous hematoma of the mesentery. Conclusions We report a case of SMH mimicking small intestinal GIST. It is difficult to diagnose long-established SMH because its radiological features change with time, and more case reports are needed to improve the accuracy of diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
