Due to individual variations in radio-sensitivity, biomarkers are needed to tailor radiation treatment. Within this frame, the identification of series of genetic signatures mainly SNPs for NPC patients treated with radiotherapy may help to predict treatment outcome and deliver personalized therapy. The aim of this study was to evaluate the possible association between the GSTP1 Ile105Val and GPX1 Pro198Leu polymorphisms and response to radiotherapy in NPC patients. Methods: From September 2016 to October 2018, a total of 101 patients with confirmed NPC, recruited at Mohammed IV Center for Treatment of Cancer of Casablanca, underwent radiotherapy. DNA was extracted from peripheral blood. Genotyping of the GPX1 Pro198Leu and GPX1 Val105Leu polymorphisms was carried out by PCR amplification and DNA sequencing. SPSS was used to analyse the association of GSTP1 and GPX1 genotypes with clinico-pathological features and response to radiotherapy. Results: The genotyping data revealed the presence of only two genotypes namely Pro/Pro (57.4%) and Pro/Leu (40.6%) for GPX1 gene. The allelic frequencies of C and T alleles were 78.7% and 21.3% respectively. For GSTP gene, the homozygous genotypes Val/Val and Leu/Leu were detected in 35.6% and 12.9% of patients respectively. The heterozygous genotype Val/Leu prevailed (51.5%). Allelic frequencies showed the presence of the two alleles A and G in 57.1% and 42.9% patients respectively. Statistical analysis failed to find any significant association between GSTP Val105Ile and GPX1 Pro198Leu genetic polymorphisms and socio-demographic and clinico-pathological features as well as response to radiotherapy (p>0.05). Conclusion: Further research is warranted on the potential role of SNPs within antioxidant defines genes in radiotherapy response and to identify reliable predictive and non-invasive biomarkers for radio-resistance among NPC patients for personalised therapies.

Both angiogenesis and cellular proliferation are core mechanisms to tumoral progression, with VEGF (Vascular Endothelial Growth Factor) and Ki-67, respec-tively, being widely known markers of those two processes. The purposes of this study are to comprehend VEGF and Ki-67’s impact on colorectal cancer prognosis which include assessing its expression in primary colorectal cancer of patients who underwent surgery, establishing associations between the expression of VEGF and Ki-67 and discovering hypothetical associations between these biomarkers and clinicopathological aspects, relapse, and mortality of patients. Methods: A retrospective study was conducted in our hospital by including 512 patients submitted to surgery, from 2005 to 2010, with a post-operatory diagnosis of colorectal adenocarcinoma. The evaluation of expression of VEGF and Ki-67 in the obtained tissue was made through immunohistochemistry technique. The statistical analysis resourced to association tests and survival analysis. Results: VEGF-A showed association with the variable gender (p-value of 0.016), with its expression being more frequent in men. VEGF-C expression is more common in colon than in rectum (p- value of 0.042). VEGF-C is significantly associated with Ki-67 (p-value of 0.036), with 69.7% of cases where both are positive. All markers are significantly associated with the grade of differentiation, with the VEGF family generally more present in well or moderately differentiated tumours and Ki-67 in the poorly differentiated. While the survival time was generally lower in the presence of any marker or combination, no significant differences were found among the survival analysis. Conclusion: VEGF-A, VEGF-C and Ki-67 expression did not show impact on the prognosis of this sample of patients. There was no significant association with a poorer overall survival or a reduced disease-free survival.","PeriodicalId":11831,"journal":{"name":"Eurasian Journal of Medicine and Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86086218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of our study[2] was to deepen the rare histologic type of renal tumor which is the chromophobe renal cancer with sarcomatoid differentiation, its mode of presentation, imaging techniques, histopathological analysis, prognostic factors, and treatment. Because it is a subject discussed in the literature but with only a few patients described, as a visual way to simplify the low incidence of this pathology, we used the results published by Bian et al.[3] on a table and added our clinical cases. With this, we reflected on the most important prognostic factors, as described in the literature, and how they affected survival. It is unquestionable that those two cases cited in Val-Bernal et al. could have enriched this table, especially because of their detailed histopathological analysis. Akhtar et al.[4] presented a left renal tumor with anaplastic spindle cells with a high mitotic rate intermingled with poorly differentiated pleomorphic tumor cells showing positivity for vimentin. In the same way, Gómez-Román et al.[5] showed a right renal mass with sheets of voluminous polygonal epithelial cells with 40% of the tumor displaying spindle-shaped and pleomorphic cells, showing epithelial cell diffuse reaction of the cytoplasm with Hale’s acid iron colloid stain and being the sarcomatoid areas reacted for vimentin. It should also be noted, as they argue in their letter, that their patient was alive 7 years after diagnosis, which is the longest survival time described in this type of patients. Nevertheless, as far as our review is concerned, we decided to focus more on the literature described in terms of prognostic factors and optimal treatment based on these than on the exact number of cases described, and that is the reason why unfortunately we did not add the case presented in 1996, which might have surely completed our series both in quantitative and qualitative terms. Please accept our apologies for any discomfort, and we hope that this will not happen again in the future as our ultimate goal is to combine the maximum knowledge with the previously described pertinent literature to manage complex patients in the best possible way.

The aim of our study was to look for new means to support the decision-making process for their management. Inflammatory biomarkers could play an important role in this process. Methods: A retrospective chart review of salivary glands tumors was performed between January 2016 and September 2020 in our Department. The samples were divided in 2 groups basing on the histological result after surgery: 191 patients with benign salivary glands tumors (SGbt), and 47 with salivary glands cancer (SGc). 90 patients were randomly selected to form the control group (C group). Results: Statistically significant increase of platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocite ratio (NLR) and systemic immune-inflammation index (SII) was reported in SGc group compared to SGbt group and control group (p<0.001). Statistical evaluation estabilished optimal threshold for PLR (164,2), NLR (3,11) and SII (517.5) that can discriminate the doubtful cases with specificity of 85-86% and 62% respectively, and sensitivity of 40-45% and 64% respectively.

Review 112 Lopes de Oliveira. et al., Role of lncRNA Alterations in Cervical Oncogenesis / doi: 10.14744/ejmo.2022.74937 Viral oncogenes E6 and E7 are consistently overexpressed after HPV genome incorporation into host cell DNA. Its incorporation leads to a series of oncogenic advances. The best-studied and known advances are induction of tumor suppressor protein p53 degradation by the viral oncoprotein E6 and cellular transformation through interaction with the PDZ domain of cellular proteins and pRb led by oncoprotein E7. The HPV16 E6/E7 proteins can also increase the expression of the polycomb repressive complex 2 (PRC2) and the methyltransferase enhancer of zeste homolog 2 (EZH2) at the level of messenger RNA (mRNA) and protein, which modify gene expression through increased histone H3 Lys27 trimethylation.[8,10,12,13] Recent studies have associated changes in expression levels of non-coding RNA molecules, such as long non-coding RNAs (lncRNAs), induced by HPV as another possible pathogenic pathway important for neoplastic process development.[14,15] Long non-coding RNAs (lncRNAs) are a class of ribonucleic acid (RNA) molecules with more than 200 nucleotides in length that do not encode proteins. They play important roles in several cellular activity regulations, such as epigenetic regulation, silencing of chromosomes, chromatin modification, transcriptional activation, post-transcriptional regulation, protein regulation, and can be used as “sponges” competitively inhibiting microRNAs (miRNAs). [7,16-18] Growing evidence has established the potential relationship between dysregulation of lncRNA expression and numerous human diseases such as cancer, metabolic diseases, neurodegenerative and psychiatric diseases, and immune dysfunction.[18-22] Numerous studies show that they play vital roles in the progression and development of various human neoplasms. The expression of lncRNAs is different in distinct tissues, and its expression may be increased or reduced. lncRNAs dysfunction is involved in tumorigenesis, from proliferation to resistance to apoptosis, angiogenesis, and metastasis.

Methods: SiHa cells were treated with estradiol, dihydrotestosterone, and cisplatin and evaluated the expression of ER beta, Ki67, and DDX3 via quantitative reverse transcription–polymerase chain reaction. We generated a chimeric fusion construct five untranslated region (UTR)–hLUC–3UTR in the pEZX-MT06 miRNA vector under the control of the SV40 promoter. Reporter activity is measured with/without hormones, and their activity is compared with 5'- and 3'-UTR respectively. Various reporter deletion constructs were generated to identify the minimal UTR region in regulating the expression of DDX3. We identified the potential miRNA binding sites on the DDX3 UTR region, and their expression is monitored in cancer patients and cisplatin-treated SiHa cells. Results: Hormones increased the proliferation of SiHa cells and expression of DDX3. The 3'-UTR region 2135–4307bp contains miRNA sites that regulate DDX3 expression. miRNAs hsa-miR-671-5p, hsa-miR-361-5p, hsa-miR-140-5p, hsa-miR-564, and hsa-miR-769-5p downregulated in patient samples but upregulated in cisplatin-treated cells. miRNA hsa-miR-671-5p and hsa-miR-564 were associated with patient data and cisplatin-treated cancer cells.

Among gynecologic cancers, Pap smear represents a gold standard diagnostic procedure for precancerous cervical lesions. It is efficiently interpreted through a standardized reporting system; The Bethesda System, which aids in distinguishing squamous categories from other entities. Co-infections with other sexually transmitted infections (STIs) could exacerbate cervical lesion severity caused by initial HPV infection as co-infections can lead to distinct reprogramming of host cells and genome integrity. The intricate pathways and effect of the unique cellular microenvironment that HPV and co-infecting STIs create that cause local inflammation and eventually cervical lesion progression will be reviewed in this manuscript. Besides, it is also crucial to consider HPV viral load and distinguish its correlation with cervical lesion severity. Varying amounts of viral titer and its impact on cervical lesions could indicate a mutagenic transformation of the human host cells and HPV. Thus, this review aims to discuss the correlation of co-infections and viral titer on cervical lesion severity and its progression to cancer.
