Programmed Death Ligand 1: Unveiling its Impact on Endometrial Carcinogenesis.

Endometrial cancer is a commonly diagnosed gynecological malignancy presenting an increasing incidence worldwide. The immune response plays a crucial role in the mechanisms underlying carcinogenesis and the progression of tumors. In recent times, there has been a discernible surge in the acknowledgment of the importance of programmed death ligand 1 (PDL1) in evading the immunological response of the host and promoting the growth of malignancies.

This study endeavors to elucidate how the long non-coding RNAs (lncRNAs) , and , as well as the microRNA , exhibit specific expression patterns in the pathogenesis and prognosis of EAC. A total of 50 EAC tissue samples (tumors and lymph nodes) and a control group comprising 26 healthy individuals were recruited.

Prospective multicenter external validation of postoperative mortality prediction tools in patients undergoing emergency laparotomy.

Background: Accurate preoperative risk assessment in emergency laparotomy (EL) is valuable for informed decision making and rational use of resources. Available risk prediction tools have not been validated adequately across diverse health care settings. Herein, we report a comparative external validation of four widely cited prognostic models.

Role of histone deacetylase inhibitors in diabetic cardiomyopathy in experimental models (Review).

In diabetes, metabolic dysregulation, caused by hyperglycemia, leads to both structural and functional changes in cardiomyocytes and subsequently leads to the development of cardiomyopathy. Histone deacetylases (HDAC) are enzymes that regulate gene transcription. Their actions have been examined in the development of multiple disorders, such as cardiovascular diseases and diabetes.

Gastrectomy for Cancer: A 15-Year Analysis of Real-World Data from the University of Athens.

Cancer Treatment and Immunotherapy during Pregnancy.

Background/aim: Immunotherapy has, in recent years, witnessed an expansion in its indications for the treatment of cancer. Coupled with the fact that, nowadays, even more women choose to postpone parenthood, thus increasing their chances of having some kind of malignancy during pregnancy, more and more women are eligible for receiving immunotherapy during this period of their lives. The cases of cancer diagnosed during pregnancy is an ever-increasing trend nowadays.

Primary Cervical Carcinosarcoma: Report of a Rare Case.

 Carcinosarcomas are malignant mixed Müllerian tumors (MMMT), containing both epithelial and mesenchymal components. Carcinosarcomas of the uterine cervix comprise an extremely rare histopathological entity, with less than 150 cases reported in the literature to date.  A 79-year-old postmenopausal female patient was referred to our gynecological department due to a pelvic mass and vaginal bleeding.

Radiation-Induced Esophageal Cancer: Investigating the Pathogenesis, Management, and Prognosis.

One of the most serious late side effects of irradiation is the promotion of tumorigenesis. Radiation-induced esophageal cancer (RIEC) can arise in a previously irradiated field, mostly in patients previously irradiated for thoracic malignancies such as breast cancer, Hodgkin and non-Hodgkin lymphomas, head and neck cancers, lung cancer, or previous esophageal cancer. RIEC is rare and accounts for less than 1% of all carcinomas of the esophagus.

Oncologic outcomes of patients with resectable primary gastric squamous cell carcinoma: a systematic review.

Background: Primary gastric squamous cell carcinoma (PGSCC) is an uncommon type of gastric malignancy estimated to comprise around 0.04-0.5% of all gastric malignancies.

The Role of SNHG15 in the Pathogenesis of Hepatocellular Carcinoma.

Long non-coding RNAs (lncRNAs) are transcripts of more than 200 nucleotides which cannot be translated into proteins. Small nucleolar RNA host gene 15 (SNHG15) is a lncRNA whose dysregulation has been found to have an important impact on carcinogenesis and affect the prognosis of cancer patients in various cancer types. Hepatocellular carcinoma (HCC) is one of the most common cancers with a poor long-term prognosis, while the best prognostic factor of the disease is its early diagnosis and surgery.

The Prognostic Role and Significance of Dll4 and Toll-like Receptors in Cancer Development.

The Notch signaling pathway regulates the development of embryonic and tissue homeostasis of various types of cells. It also controls cell proliferation, variation, fate and cell death because it emits short-range messages to nearby cells. The pathway plays an important role in the pathophysiology of various malignancies, controlling cancer creation.

A Brief Overview of Oncogenes and Signal Transduction Pathways in Gynecological Cancer.

Gynecological cancer is the cancer that originates in the female reproductive system. According to the anatomical location of the cancer, it is distinguished into cervical, uterine, vaginal, ovarian, and vulvar cancer. Oncogenes and tumor catalytic genes play a key role in the genesis and development of gynecological cancer.

Concomitant Existence of Bilateral Adrenal Adenomas. To Operate or Not?

Nowadays, through the wide use of both magnetic resonance imaging and computed tomography, the diagnosis of adrenal incidentaloma is becoming increasingly frequent. Pheochromocytomas are neuroendocrine tumors which produce catecholamine, and they are characterized by headaches, palpitations, sweating and hypertension. Aldosterone-secreting adrenal cortical adenomas can cause various metabolic and cardiovascular diseases due to aldosterone excess.

Targeting the Endocannabinoid System: From the Need for New Therapies to the Development of a Promising Strategy. What About Pancreatic Cancer?

Pancreatic cancer is one of the most fatal malignancies, and therefore, new strategies, which aim at the improvement of the prognosis of this lethal disease, are needed. Many clinical trials have failed to improve overall survival. Nowadays, research is focused on advances provided by novel potential targets to efficiently enhance life expectancy.

The Impact of Nutritional and Functional Status on Postoperative Outcomes following Esophageal Cancer Surgery.

Malnourished patients undergoing esophagectomy have increased risk of postoperative complications. The aim of the current study was to identify nutritional and functional risk factors for postoperative complications in patients with esophageal and gastroesophageal junction cancer who underwent esophagectomy. Seventy patients who were admitted at the First Department of Surgery, Laikon General Hospital, Athens, Greece, were included in this study.

All that Glitters is not Cholecystitis. A Rare Presentation of Acute Pericarditis Mimicking Cholecystitis and Review of the Literature.

Acute pericarditis is the most common inflammatory disorder of the pericardium, responsible for approximately 5% of visits to the emergency departments, concerning chest pain without myocardial infarction.
