Urinary estradiol production rates, plasma estradiol, and peripheral conversion of dehydroepiandrosterone sulfate (DHEAS) to estradiol were explored in patients whose neoplasms made human chorionic gonadotropin and/or human chorionic gonadotropin beta fragments. In five men with choriocarcinoma, estradiol production was elevated, plasma estradiol was high, and DHEAS conversion to estradiol rang...

BACKGROUND Hepatoid carcinomas (HCs) are extrahepatic neoplasms exhibiting features of hepatocellular tumors in terms of morphology and immunohistochemistry. They have been described in several organs, most notably in the stomach and ovary. They can present in pure forms or in association with other morphological aspects, such as endocrine tumors or ductal adenocarcinomas. The aim of this revie...

Primary gastrointestinal (GI) lymphomas constitute less than 8 % per cent of total gut neoplasms. Most of them are Non-Hodgkin’s type of Lymphomas. Among the Extra-nodal tissues Gastro-intestinal tract is the most common site followed by Head and Neck region, Central nervous system, Thorax, Spleen, Adrenal glands, Uro-genital tract, skin and Bone. The stomach is the most common location of GI l...

synchronous cancer is referred to two or more histological distinct malignancies diagnosed during the same hospital admission. globally more than 1 million people get colorectal cancer yearly resulting in about 0.5 million deaths. vulvar cancer is the fourth most common gynecologic cancer (following the corpus uterine cancer, cancer of ovary and cervix) and comprises only 4 percent of malignanc...

Leiomyomas constitute 2.5% of all resected neoplasms of the stomach. They are usually asymptomatic, but may present mucosal ulceration. Aberrant DNA methylation is a well-defined epigenetic change in human neoplasms; however, gene-acquired methylation may not necessarily be related with a malignant phenotype. In this report we analyzed in a gastric leiomyoma, the methylation status of 84 CpGI i...

Introduction. Cancer is the second cause-of-death mortality pattern in Republic of Moldova. The study both cancer by age and its detailed causes an important tool for evidence-based public health policy. aims at comparing recent changes with long-term trends, depending on specific age. 
 Material methods. This was carried out reconstructed 1965-2018 death time series, according to 10th rev...

The normal pathways of lymphatic drainage from the abdominal organs have been well described in the classic anatomy literature. Knowledge of the location and nomenclature of the common nodal stations in the abdomen are essential for complete report of radiological findings. CT is ubiquitous in the evaluation of oncology patients. Utilizing colour-coded CT images of the abdomen we will present t...

CONTEXT Somatostatin-producing endocrine tumors of the duodenum are very rare neoplasms of the gastrointestinal tract. These tumors may be associated with von Recklinghausen's disease. CASE REPORT We present the case of a 49-year-old female patient with von Recklinghausen's disease and an incidentally diagnosed ampullary neoplasm. The patient was treated with a classical pancreaticoduodenecto...

BACKGROUND Analysis of trends in cancer survival in defined well surveilled populations can provide useful indications on advancements in cancer management and treatment. PATIENTS AND METHODS Survival rates from the Vaud Cancer Registry were computed for 31,158 cases registered in 1984-1993, and compared with those registered in 1974-1978 and 1979-1983. RESULTS A systematic, albeit generall...
