Neuroendocrine tumors of the gynecological tract: A narrative literature review.

Neuroendocrine neoplasms (NENs) of the gynecological tract are a rare, heterogenous and aggressive group of neoplasms, with high recurrence rates and poor prognosis. In this review we focus on NENs of the gynecological system emphasizing the classification, epidemiological and clinical characteristics of NENs across the gynecological tract (cervix, endometrium, ovary, vagina, and vulva), risk/prognostic factors, pathology and molecular biology (including actionable genomic mutations), imaging, staging and the most effective treatment modalities in the "standard of care" approach as well as the pipeline products. We also focused on metastatic spreading patterns of gynecological NENs.

Programmed cell death-1 and its ligands: Current knowledge and possibilities in immunotherapy.

Programmed Cell Death-1 (PCD-1) is a key immune checkpoint receptor, which mainly expresses on activated T, B, Dendritic (DC), Natural Killer (NK), and Treg cells. On the surface of activated T-cells, PCD-1 expression is upregulated after the recognition of peripherals antigens by T cells; subsequently, the elevated binding of PD-1 to Programmed Death Ligand-1 (PD-L1) and Programmed Death Ligand-2 (PD-L2) becomes a key step for downstream inhibitory signaling. Although the role of PD-L1 has been evaluated more thoroughly by clinical research, and PD-L1 has also been used more widely in the clinical setting, PD-L2 also plays an important role in the negative regulation of T-cells, one of the necessary conditions that lead to immune tolerance.

E6/E7 mRNA Expression of the Most Prevalent High-Risk HPV Genotypes in Cervical Samples from Serbian Women.

Cervical cancer caused by persistent infection with HR HPV genotypes is the second leading cause of death in women aged 15 to 44 in Serbia. The expression of the E6 and E7 HPV oncogenes is considered as a promising biomarker in diagnosing high-grade squamous intraepithelial lesions (HSIL). This study aimed to evaluate HPV mRNA and DNA tests, compare the results according to the severity of the lesions, and assess the predictive potential for the diagnosis of HSIL.

HISTOPATHOLOGIC PARAMETERS OF POSITIVE LYMPH NODE PREDICTABILITY IN ENDOMETRIAL CANCER.

Endometrial cancer is the most common malignancy of the female reproductive tract. Lymph node metastases are an important prognostic factor in endometrial cancer. Several prognostic factors have been shown to correlate with lymph node metastasis, including depth of myometrial invasion, cervical infiltration, histologic grade of the tumor, tumor diameter, histology type, lymphovascular invasion, and positive peritoneal cytology.

Association of Peritoneal Cytology with Other Prognostic Factors in Endometrial Cancer.

Purpose: It is still debatable whether surgical staging of endometrial cancer (EC) should include sampling of peritoneal cytology (PC) and for what purpose this should be done. The aim of our study was to determine the significance of peritoneal cytology in EC and its association with other histological and clinical parameters.

Methods: This is a retrospective study that comprises of results from 357 patients with EC that were operated in our center in the previous nine years.

Oxidative stress and its role in cancer.

Reactive oxygen species (ROS) can damage lipids, nucleic acids, and proteins, thereby altering their functions. When a balance between production of ROS and antioxidative defense is disturbed, state of oxidative stress occurs. Oxidative stress leads to many diseases.

Histopathological correlation of cervical biopsy and tissue after excision in patients with precancerous lesions of the cervix.
