Penile cancer (PC) is a typical tumor of non-industrialized countries. The incidence is 20-30 times higher in Africa and South America, considering the elevated prevalence of sexually transmitted diseases. Histologically, PC includes squamous cell carcinoma (SCPC), the most frequent, and nonsquamous carcinoma (NSCPC). Early diagnosis is the goal, whereas later diagnosis relates to poor functional outcomes and worse prognosis. The 5-year survival rate is 85% for patients with histologically regional negative lymph nodes, compared to 29%-40% for those with histologically regional positive lymph nodes. To date no new drugs are approved, and there are few new data about molecular mechanisms underlying tumorigenesis. The SCPC remains a rare tumor and the current therapeutic algorithm is based principally on retrospective analysis and less on prospective trials. In this review article, biomarkers of prognosis and efficacy of current treatments are summarized with a focus on those that have the potential to affect treatment decision-making in SCPC.
Retinoblastoma (RB) is a common intraocular tumor of infancy and childhood. Circular RNAs (circRNAs) are related to the development of RB. The purpose of this research was to reveal the functional mechanism of circRNA circ_0000034 in RB.

Quantitative Real-Time Polymerase Chain Reaction (qRT-PCR) and Western blot were applied to determine the levels of genes. MTT assay and flow cytometry were employed to assess cell proliferation and apoptosis rate, respectively. GSK2245840 Furthermore, cell migratory and invasive abilities were measured using the transwell assay. Mouse xenograft was conducted to analyze the effect of circ_0000034 on tumor growth in vivo. Besides, the interaction between miR-361-3p and circ_0000034 or syntaxin 17 (STX17) was predicted by starBase, and then, confirmed by the Dual-Luciferase reporter assay and RNA immunoprecipitation (RIP) assay.

The levels of circ_0000034 and STX17 were increased and miR-361-3p level was decreased in RB tissues and cells. Circ_0000034 knockdown suppressed cell proliferation, migration, invasion, autophagy, and tumor growth, and induced apoptosis in RB. Circ_0000034 targeted miR-361-3p and miR-361-3p bound to STX17. Circ_0000034 overexpression and miR-361-3p knockdown reversed the effect of miR-361-3p upregulation and STX17 depletion on the growth of RB cells, respectively. Besides, circ_0000034 elevated STX17 level by repressing miR-361-3p expression.

We demonstrated that circ_0000034 knockdown suppressed the development of RB by the modulation of miR-361-3p/STX17 axis. Our findings provided a theoretical basis for the treatment of RB.

The aim of this study was to explore the association between TP53 gene polymorphisms (rs8068934 A>G and rs218698 C>T) and chronic lymphocytic leukemia (CLL).

CLL patients who received treatment in our hospital were enrolled in this study as the disease group. Meanwhile, healthy subjects were taken as the control group. Peripheral blood samples were collected to detect TP53 gene polymorphisms at rs8068934 and rs218698, and the haplotype analysis was performed. The expression of TP53 was detected via reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Furthermore, the survival conditions were analyzed.

The allele distribution at rs8068934 (p=0.046) and rs218698 (p=0.028) of TP53 gene was different between control group and disease group. A allele frequency at rs8068934 and T allele frequency at rs218698 were significantly higher in disease group (p<0.05). The genotype distribution at rs218698 of TP53 gene in disease group was also different from that in control group (p=0.038)type showed significantly lower level of PLT (p<0.05). TP53 gene polymorphisms at rs218698 were associated with the level of red blood cells (RBC) (p=0.000). Patients with CT genotype had a remarkably lower level of RBC (p<0.05). There were significant correlations of TP53 gene polymorphisms at rs8068934 (p=0.000) and rs218698 (p=0.000) with the expression of TP53. The expression of TP53 was lower in people with AA genotype at rs8068934 but higher in people with TT genotype at rs218698 (p<0.05). Furthermore, TP53 gene polymorphisms at rs8068934 (p=0.000) and rs218698 (p=0.000) were markedly associated with patients' survival.

TP53 polymorphisms are significantly correlated with the occurrence and progression of CLL.

The aim of this study was to explore the influences of micro ribonucleic acid (miR)-150 on the proliferation and apoptosis of mantle-cell lymphoma (MCL) cells and to investigate the potential underlying mechanism.

Differentially expressed miRNAs in MCL tissues were excavated via microarray analysis of miRNA expression profiles. Subsequently, the expression of miRNAs were verified by quantitative Reverse Transcription-Polymerase Chain Reaction (RT-qPCR). The influence of miRNA expression on the survival of patients was detected based on clinical data. Besides, the potential targets of miRNAs were determined using Luciferase reporter gene assay combined with qRT-PCR and Western blotting. Primary tumor cells were extracted, and the influences of miR-150 expression on cell proliferation were detected via Cell Counting Kit (CCK)-8 assay and 5-ethynyl-2'-deoxyuridine (EdU) staining assay. Finally, Western blotting and flow cytometry were performed to explore the impact of miR-150 on the apoptosis of primary tumgulating MET expression.
MiR-150 inhibits the proliferation and promotes the apoptosis of MCL cells by negatively regulating MET expression.The assessment of tumor response, after neoadjuvant radiochemotherapy (nCRT), allows stratifying the patient in order to consider the proper therapeutical management. Histopathology analysis of the surgical specimen is considered the gold standard to assess tumour response and the definition of a complete cancer response is related to the clinical and endoscopic features, by direct evaluation of the rectal wall. However, imaging studies, especially Magnetic Resonance Imaging (MRI) have provided additional parameters, as the evaluation of nodal or mesorectal status. MRI provides a radiological tumour regression grade (mrTRG) that is correlated with the pathologic tumor regression grade (pTRG). Functional MRI parameters have additional impending in early prediction of the efficacy of therapy and can be valuable in drug development processes. Some of functional methodologies are already part of clinical practice diffusion-weighted MRI (DW-MRI) and perfusion imaging (dynamic contrast enhanced MRI [DCE-MRI]). Other technologies, such as radiomics with MRI are still in the experimental phase.
