Metastatic SMARCA4-deficient undifferentiated tumor in the small mesentery: case report.

Background: SMARCA4-deficient undifferentiated tumor (SMARCA4-UT) is a rare and highly malignant primary tumor characterized by the loss of SMARCA4 expression. Despite advancements in oncology, diagnosing and treating SMARCA4-UT remain significant clinical challenges.

Case Demonstration: A 67-year-old male with a history of smoking presented to the hospital with complaints of abdominal distention and pain lasting for more than four days.

Establishment and characterization of a new intestinal-type ampullary carcinoma cell line, DPC-X3.

Ampullary carcinoma (AC) of the intestinal type represents a distinct variant within the broader category of ampullary neoplasms. The scarcity of pertinent cellular models has constrained investigations centered on this particular malignancy. This research effectively generated a cell line (CL) of intestinal-type AC (DPC-X3).

Small intestinal metastasis from primary breast cancer: a case report and review of literature.

Small intestinal metastasis from primary breast cancer remains a rare clinical occurrence. Despite extensive research into its clinicopathological features and treatment options, the specific pathogenesis and optimal management strategies remain incompletely understood. This case report presents a patient with breast cancer that metastasized to the small intestine.

Giant Duodenal Brunneroma: Report of a Rare Case and Review of the Literature.

BACKGROUND Brunneromas are among the rarest benign tumors of the upper gastrointestinal tract. They arise from the Brunner's glands and patients have a good prognosis if treated timely and radically. Because symptoms are rare, their diagnosis can be challenging, especially regarding the smaller ones.

Epidemiology, treatment and outcomes of gastroenteropancreatic neuroendocrine neoplasms.

To investigate incidence, treatment patterns and outcomes of gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN) in the United States. The 2019 National Cancer Database was searched for adult GEP-NEN patients. Main outcomes included overall and site-specific incidence, treatment patterns, and overall survival (OS).

Incidence and survival of rare adult solid cancers in Europe (EUROCARE-6): A population-based study.

Background: Rare cancers correspond to approximately 200 clinical entities, which can be grouped into 12 families. Updated data are available for childhood and haematological cancers, ie, for only two of the 12 families of rare cancer. We provide incidence and survival for the remaining ten families of rare adult solid cancers (RAC), across 29 EU Member States and over time.

ROBOTIC PANCREATICODUODENECTOMY FOR THE TREATMENT OF A MIXED NEUROENDOCRINE-NON-NEUROENDOCRINE NEOPLASM (MINEN) OF THE AMPULLA OF VATER.

Mixed neuroendocrine-non-neuroendocrine tumors (MiNEN) are a rare type of tumor formed by two components, a non-neuroendocrine component that is most often an adenocarcinoma and a neuroendocrine tumor, and each of these components must represent at least 30% of the tumor. The origin of this tumor on the ampulla of Vater or periampullary region is more infrequent. Usually, the lesions are highly aggressive and quickly metastasizing, and their biological behavior is dictated by the high grade of the neuroendocrine component.

The impact of setup errors on dose distribution in cervical cancer radiotherapy and the margin from CTV to PTV.

Purpose: This study calculates the needed margin from clinical target volume (CTV) to planning target volume (PTV) in IMRT for cervical cancer. It also assesses the impact of setup errors on target and organ at risk (OAR) dose distribution.

Methods: We retrospectively analyzed 50 cervical cancer patients who underwent IMRT, with 210 CBCT scans.

Esophago-jejunal anastomosis with open approach using the parachute technique to prioritize safety after resection of esophagogastric junction cancer.

Background: The appropriate extent of resection for esophagogastric junction cancer and the method of surgical approach remain controversial. This study aimed to assess the safety and outcomes of the parachute technique, which is an open transhiatal reconstruction method that facilitates stable reconstruction.

Materials And Methods: The surgical outcomes of 20 consecutive patients who underwent open lower- esophagogastrectomy for EGJ cancer at Kitasato University Hospital from June 2019 to July 2023 were retrospectively reviewed.

Monte Carlo study of organ doses and related secondary cancer risk estimations for patients undergoing prostate radiotherapy: Algerian population-based study.

The present study aimed to assess organ doses and the associated cancer risks related to secondary radiation (photons and neutrons) exposure during 3D Conformational Radiotherapy (3D-CRT) for patients with prostate cancer in Algeria. To this purpose, a detailed geometric Monte Carlo (MC) modeling of the LINAC, combined with a hybrid whole-body phantom was carried out. The secondary radiation doses were calculated in patient's organs, both within and outside the field.

LINE-1 hypomethylation characterizes the inflammatory response in coeliac disease associated-intestinal mucosa and small bowel adenocarcinomas.

Long interspersed nuclear elements 1 (LINE-1) are the most abundant and the only autonomous mobile elements in the human genome. When their epigenetic repression is removed, it can lead to disease, such as autoimmune diseases and cancer. Coeliac disease (CeD) is an immune-mediated disease triggered by an abnormal T-cell response to dietary gluten and a predisposing condition of small bowel adenocarcinoma (SBA), frequently characterized by epigenetic alterations.

Clinical presentation, investigation findings, and treatment outcomes of intraluminal small intestinal obstruction by bezoars and other materials in adult cows- a retrospective study of 110 cases.

Background: Small intestinal obstruction (SIO) is a blockage of the intestinal lumen by blunt foreign bodies, neoplasms originating from the intestinal wall or thick chyme. This study analysed the medical records (only data) of 110 cattle with SIO and described the clinical findings, treatment and outcome. These findings were compared between surviving and non-surviving cattle, and among the affected regions such as the duodenum, jejunum and ileum.

[A Case of Giant Intra-Abdominal Desmoid Tumor-A Case Report].

The patient was a 47-year-old woman. She had been aware of abdominal distension for several months and visited our hospital. Contrast CT revealed a 30 cm tumor with uneven contrast effect.

[A Case of Laparoscopic Surgery for Malignant Lymphoma of the Small Intestine with Bowel Obstruction].

An 80-year-old woman presented to our hospital complaining of nausea and abdominal distention. An abdominal computed tomography scan revealed wall thickening of the small intestine, a dilated oral intestinal tract, swollen intra-abdominal lymph nodes, and splenomegaly. Moreover, the soluble interleukin-2 receptor level was increased at 2,120 U/mL.

The effects of antioxidant administration in the early stages of radiation-induced tumorigenesis.

ApcMin/+ mouse was a model mouse for human familial adenomatous polyposis, and irradiation at an early age increases tumors in the small and large intestine. To study the effects of antioxidant administration on tumor incidence after continuous whole-body exposure to gamma rays, ApcMin/+ mice were exposed to a medium-dose-rate, 200 mGy/d, from postnatal Day 0 to 21 of age or a high-dose-rate of 0.65 Gy/min (total dose 4.
