Size reduction of gastric fundic gland polyposis by de-escalation of acid-suppressive therapy.

The patient, a 73-year-old woman, had been taking acid-suppressive therapy for refractory reflux esophagitis for 10 years. A potassium-competitive acid blocker was administered to strengthen acid-suppressive therapy for worsening symptoms of gastroesophageal reflux disease. Esophagogastroduodenoscopy showed an increase in the number and size of fundic gland polyposis (FGPs).

Recent Advances in Endosonography-Elastography: Literature Review.

Ultrasonographic elastography is a modality used to visualize the elastic properties of tissues. Technological advances in ultrasound equipment have supported the evaluation of elastography (EG) in endosonography (EUS). Currently, the usefulness of not only EUS-strain elastography (EUS-SE) but also EUS-shear wave elastography (EUS-SWE) has been reported.

Inflammatory myofibroblastic tumor of ileum with intussusception in adult.

A 62-year-old man was referred to our department with suspected intussusception due to an ileal tumor. Tumor markers including soluble interleukin-2 receptor were not elevated. Contrast-enhanced computed tomography and color Doppler ultrasonography showed a distinct ileal tumor without intratumoral blood flow or surrounding lymphadenopathies.

Mediastinal Neuroendocrine Carcinoma Slowly Growing for 8 Years after Surgical Resection of Esophageal Squamous Cell Carcinoma.

A 70-year-old woman was referred to our department due to a solitary mediastinal tumor which gradually grew near the site of anastomosis for 8 years after radical surgery of esophageal squamous cell carcinoma. It was difficult to distinguish the lymph node recurrence of esophageal cancer from another tumor of unknown primary origin. Endoscopic ultrasound-guided fine-needle aspiration was performed, and the tumor was diagnosed to be neuroendocrine carcinoma.

A case of advanced gastric cancer showing HER2 positivity after chemotherapy.

A 63-year-old man had advanced poorly differentiated gastric adenocarcinoma with para-aortic lymph node metastases. No HER2 expression was observed in four endoscopic biopsies from the primary tumor. Tumors shrunk after S-1 with cisplatin treatment, and he underwent simple gastrectomy due to stenosis.

A case report: Long-term complete response of metastatic hepatocellular carcinoma obtained after discontinuation of 2-month sorafenib monotherapy.

A 69-year-old woman who had a history of chronic hepatitis C, autoimmune hemolytic anemia and myelodysplastic syndrome was treated with sorafenib at a daily dose of 400 mg for HCC with multiple lung metastases. Nonetheless, elevated serum tumor markers further increased (alpha fetoprotein from 121,100 to 348,660 ng/ml and protein induced by vitamin K absence/antagonist-II from 3435 to 29,357 mAU/ml), and lung metastatic lesions on chest X-ray showed no improvement after 2 months of sorafenib treatment. Sorafenib was discontinued because of adverse events with diarrhea, fatigue, and severe anemia due to bleeding from stomach telangiectasia.

Splenic rupture caused by pancreatic pseudocyst successfully treated by endoscopic ultrasound-guided drainage.

A 43-year-old man was admitted to a local hospital because of acute left abdominal pain. Chronic alcoholic pancreatitis and a 10-cm pancreatic pseudocyst in the tail of the pancreas had been found 5 years previously. He had not stopped drinking alcohol since then.

Anal canal adenocarcinoma with neuroendocrine features accompanying secondary extramammary Paget disease, successfully treated with modified FOLFOX6: a case report.

Background: Anal canal cancer occasionally accompanies extramammary Paget disease. Although most of them are squamous cell carcinoma, anal canal adenocarcinoma with neuroendocrine features accompanying secondary extramammary Paget disease has never been reported.

Case Presentation: Here, we report a 76-year-old man presented with pruritus in the perianal area.

Successful Long-term Management with a Single Administration of Tri-weekly Nab-paclitaxel in a Patient with Advanced Gastric Cancer with Peritoneal Dissemination.

Nanoparticle albumin-bound (nab)-paclitaxel has shown promising activity in advanced gastric cancer treatment. We herein report a case of advanced gastric cancer involving long-term management with a single administration of nab-paclitaxel. A 71-year-old man diagnosed with advanced gastric cancer with malignant ascites was treated with nab-paclitaxel as a second-line chemotherapy.
