Sir, It is well known that dermatomyositis (DM) is frequently associated with internal malignancy (1 ^ 2). Common malignant neoplasms found in association with DM are breast, lung, ovary, stomach and colon. Among such malignancies, testicular tumour appears to be rare and we found only one published case report of this combination (3). We report here a case of DM associated with a testicular tu...

The incidence of gastric adenocarcinoma in animals is extremely low (13,14), and attempts to produce such tumors with various carcinogenic agents (11), including ionizing radiations (8), have been only moderately successful, at best. The present report deals with a number of malignant and premalignant lesions of the glandu lar stomach of the mouse occurring after wholebody irradiation with x-ra...

This paper presents the updated Polish Neuroendocrine Tumour Network expert panel recommendations on the management of neuroendocrine neoplasms (NENs) of the stomach and duodenum, including gastrinoma. The recommendations discuss the epidemiology, pathogenesis and clinical presentation of these tumours as well as their diagnosis, including biochemical, histopathological and localisation diagnos...

Gastrointestinal stromal tumors (GISTs) are rare mesenchymal neoplasms of the gastrointestinal tract (1%), and stomach is the most common location involved. However, the co-existence of gastric adenocarcinoma and GIST is very rare. A case of an 80-year-old male with a simultaneous presentation of a gastric adenocarcinoma and GIST is presented. Various hypotheses have been proposed in order to e...

Gastrointestinal stromal tumors (GISTs) are unique neoplasms that occur throughout the gastrointestinal tract, mesentery, omentum, and retroperitoneum. Because most GISTs arise within the muscularis propria of the stomach or intestinal wall, GISTS most commonly have an exophytic growth pattern; intramural and intraluminal masses are less common manifestations. Calcification is an unusual featur...

Mutations in the chromatin remodeling gene ARID1A have recently been identified in the majority of ovarian clear cell carcinomas (OCCCs). To determine the prevalence of mutations in other tumor types, we evaluated 759 malignant neoplasms including those of the pancreas, breast, colon, stomach, lung, prostate, brain, and blood (leukemias). We identified truncating mutations in 6% of the neoplasm...

AIM To study cancer hotspot mutations by next-generation sequencing (NGS) in stool DNA from patients with different gastrointestinal tract (GIT) neoplasms. METHODS Stool samples were collected from 87 Finnish patients diagnosed with various gastric and colorectal neoplasms, including benign tumors, and from 14 healthy controls. DNA was isolated from stools by using the PSP® Spin Stool DNA Plu...

Background: Bone marrow is the site of many malignant disorders and it is one of the common places for solid tumors to metastasize. Examination of the bone marrow aspirate and biopsy is a routine procedure performed for assessment of various conditions such as cytopenias, hematologic neoplasms, nonmalignant disorders and metastatic neoplasms. Methods: The patients were referred to the Hema...

Objetiva-se investigar a influência da sarcopenia em complicações pós-operatórias nos pacientes submetidos à gastrectomia por câncer gástrico. Utilizaram-se as bases de dados PubMed, Cochrane, Science Direct e SciELO, com estratégia busca Sarcopenia and Stomach Neoplasms. A revisão integrativa foi estruturada 15 artigos, publicados no período 2015 2019. análise dos realizada forma descritiva. D...
