Background/Aim: miRNA expression patterns vary within primary rectal cancers and play a pivotal role in carcinogenesis. It is unknown, however, if these regulatory changes also play a role in local recurrent rectal cancers. In this study, the expression of various angiogenetic small non-coding ribonucleic acids, namely miRNA-21, miRNA-215, miRNA-221, and miRNA-222 were analysed in cancerous and healthy rectal tissues. Patients and Methods: miRNA expression was analyzed via quantitative polymerase...

A Review of Stereotactic Body Radiation Therapy in the Management of Oligometastatic Prostate Cancer
Background/Aim: Management strategies such as surgery and systemic therapy (androgen-deprivation therapy and chemotherapy) are considered a standard of care for patients with oligometastatic prostate cancer and have shown some positive results in many patients. However, they are often accompanied by side-effects that can negatively affect patients. The aim of this study is to review the potential of stereotactic body radiation therapy (SBRT) in the management of oligometastatic prostate cancer and...

Endometriosis is an estrogen-dependent disease, which affects 10% of women in the reproductive age. Malignant transformation is an uncommon event, which affects approximately 0.7-2.5% of women, and, when it occurs, it involves ovarian and extraovarian sites in 75% and 25% of the cases, respectively. Endometriosis correlates with presentation of clear cell and endometrioid carcinoma of the ovary. Activation of phosphatidylinositol 3-kinase (PIK3) – protein kinase B (AKT) – mammalian target of rapamycin...

Large cell neuroendocrine carcinoma (LCNEC) of the urinary tract is a high-grade neuroendocrine tumor with distinct pathological features, usually portending an aggressive clinical behavior in comparison to conventional urothelial carcinoma. Due to its low prevalence, little is known about its clinical management and there is no current standard of care. The aim of this review was to summarize the current knowledge about LCNEC of the bladder, ureter and kidney, with relevance to diagnostic, prognostic...

The maintenance of genome integrity is essential for cellular survival and propagation. It relies upon the accurate and timely replication of the genetic material, as well as the rapid sensing and repairing of damage to DNA. Uncontrolled DNA replication and unresolved DNA lesions contribute to genomic instability and can lead to cancer. Chromatin licensing and DNA replication factor 1 (Cdt1) is essential for loading the minichromosome maintenance 2-7 helicase complex onto chromatin exclusively during...

The introduction of tyrosine kinase inhibitors (TKIs) directed against the catalytic activity of the ABL tyrosine kinase has considerably improved the outcome of chronic myeloid leukemia (CML) patients in the chronic phase of the disease. Indeed, these individuals currently show a life-expectancy comparable to those of healthy subjects. Currently, five TKIs (imatinib, dasatinib, nilotinib, bosutinib and ponatinib) are approved for the treatment of CML and can be used as first, second or further lines...

Background/Aim: The hormonally-active form of vitamin D, 1,25(OH)2D3, demonstrated activity against oral squamous cell carcinoma (OSCC). Cytochrome P450scc (CYP11A1)-derived vitamin D hydroxyderivatives, such as 20(OH)D3 and 1,20(OH)2D3, have overlapping beneficial effects with 1,25(OH)2D3 without causing hypercalcemia. This study sought to determine (i) whether 20(OH)D3 and 1,20(OH)2D3 exhibit antitumor effects against OSCC comparable to those of 1,25(OH)2D3 and (ii) whether these effects may stem...

Background: Immune checkpoint inhibitors (ICI) have changed the management of cancer dramatically. However, not all patients respond to ICI and their use places patients at a significant risk of immune-related adverse reactions. A few biomarkers including programmed death-1 receptor/programmed death-ligand 1 (PD-1/PD-L1), micro-satellite instability (MSI) status, and tumor mutational burden (TMB) have gained popularity as surrogates to predict responsiveness to ICI. Case Report: Herein, we report...

Background/Aim: Mast cell transformation, as manifested in mastocytosis, can be a serious condition for which there are limited therapeutic options. Mastocytosis cells can be sensitive to histone deacetylase (HDAC) inhibitors, but their sensitivity to other histone-modifying enzymes has not been assessed. Here we addressed this issue. Materials and Methods: Inhibitors of histone methyl transferases, histone demethylases, histone acetyl transferases and HDACs were tested for their effects on growth,...

Background/Aim: This study aimed to improve the prognostic significance of neutrophil-to-lymphocyte ratio (NLR) and tumour-infiltrating lymphocytes (TILs). Patients and Methods: In this retrospective study, NLR and TIL data from 677 operated breast cancer patients were analysed. The cut-off value of NLR was set at 2.72, and TIL levels were classified as low (<10%), intermediate (≥10 to <50%), and high (≥50%). Results: Recurrence-free survival (RFS) was significantly longer in patients with...

Background: The Japanese bladder cancer treatment guidelines recommend concurrent chemoradiotherapy, including wide pelvic irradiation. Many elderly patients, however, cannot tolerate standard treatment because of low performance status. Therefore, to reduce complications, elderly patients sometimes receive radiation therapy without elective nodal irradiation or chemotherapy. Patients and Methods: Outcomes were retrospectively analyzed in 19 elderly patients with N0 muscle-invasive bladder cancer...

Background/Aim: We previously showed that oxaliplatin induces necrotic-like cell death in hepatocarcinomas, and combination with ursodexoycholic acid (UDCA) significantly shifts the necrotic-like death to apoptosis. Since cell death mode is crucial on inflammatory responses and chemotherapeutic efficacy, the mechanism underlying determination of cell death mode by UDCA was investigated in this study. Materials and Methods: Apoptosis or necrosis was determined by apoptotic body formation, caspase-8...
