Materials and Methods: A total number of 30 cases of per cutaneous CT guided biopsies of primary non-small lung cancer were collected in the pathology department of Misr University for Science and Technology Giza, Egypt and private practice in the time period from January 2018 till December 2020. Immunohistochemical study for neuroendocrine differentiation was performed using mono clonal antibodies against synaptophysin, chromogranin A and CD56. For all selected cases, clinical and pathological data such as age, gender, histologic types, grade and clinical stage were collected, tabulated and statistically analyzed with the results of neuroendocrine markers expression. Cases with incomplete pathological data and cases with histologic picture of neuroendocrine differentiation were excluded. Results: A total number of 30 cases of primary non-small lung cancer were enrolled in this study. The median age of patients was 61.5 years. There were 21 (70%) males and 9 (30%) females. Regarding neuroendocrine markers, positivity for either marker was identified in 23.3% of non-small cell lung cancer. Chromogranin A was positively expressed in 9 (30%) of cases, synaptophysin was positively expressed in 7 (23.3%) of cases and CD56 was positively expressed in 5 (16.7%) of cases. Only 2 cases (6.7%) showed co-expression of two markers. It was found that there was a high significant relation between chromogranin A expression and clinical stage. Chromogranin A expression was significantly higher in stage III than stage I and II (P<0.001). There was no statistical significant difference between synaptophysin, chromogranin A and CD56 expressions and the rest of the studied pathologic data. Conclusion: A considerable number of non-small cell lung cancer has neuroendocrine differentiation for at least one neuroendocrine marker despite absence of morphologic features. Much less number of cases showed expression of two markers. A reasonable panel of neuroendocrine markers is recommended to detect this differentiation which may have a clinical impact and optimize an alternative therapeutic option. ","PeriodicalId":8848,"journal":{"name":"Asian Pacific Journal of Cancer Biology","volume":"271 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74368944","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}

Appropriate tumor markers may serve as diagnostic aid to better decision making in the management of these cases. We attempted to determine the relationship between age, serum markers, and histopathological sub types of ovarian tumors to help distinguish benign from malignant tumors.Methods: A retrospective cross sectional study of all cases with ovarian tumors that had available histopathology reports and tumor marker levels was done at a single centre. Variables examined were age, histopathology report and serum tumor markers CA-125, CEA, CA19-9, LDH, and βHCG. Results: Histopathological analysis revealed 26% teratomas, 28% cystadenomas, 14% corpus luteal cysts, 26% carcinomas and 6% endometriomas. CA-125 was the only marker that was significantly raised in malignant versus benign tumors (p=0.008) and increased with increasing age. All women with raised CEA reports had teratomas, and none with cancers had a raised CEA. CA19-9, LDH and βHCG were not significantly different in benign versus malignant tumors.Conclusions: CA-125 may be used as an adjuvant diagnostic tool for ovarian cancer in older women. The role of CEA as a marker for teratomas needs further evaluation.","PeriodicalId":8848,"journal":{"name":"Asian Pacific Journal of Cancer Biology","volume":"92 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82184592","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}

In West Africa most have been carried out on all gynaecological and breast cases to describe the epidemiological features and management modalities.Methods: Our research covered a period from 1998 to 2018. The terms “gynaecological cancers” and “West Africa”; are used to find records in the research databases (PubMed, ScienceDirect, Scopus and Google Scholar). There are countries (Cape Verde, Guinea, Gambia, Liberia, Sierra Leone) in which we have not found any work in the research databases. The process for selecting studies followed selection steps based on PRISMA 2009. Result: Cervical cancer is the commonest, followed by breast cancer, ovarian cancer, uterine or endometrial cancers, vaginal cancer and vulvar cancer. The lowest common was tubal cancers. The two English-speaking countries, Nigeria and Ghana, recorded 60 (60.82%) and 16 (15.68%) articles published respectively. At the same time, these two countries reported the most cases of gynaecological cancers including 72,848 cases (68.97%), 12, 327 cases (11.67%) and 12, 021 cases (11.38%) for Nigeria, Cote d’Ivoire and Ghana respectively. West Africa countries are characterised by poor outcome due to ignorance, superstition, self-denial, late presentation and unavailability of treatment facilities. Conclusion: Our study suggests that comprehensive national health insurance schemes as well as preventive strategies, patient and health work force education may improve the current situation. Also, West African countries must necessarily have a policy of acquiring the technical platforms to carry out these diagnostic and prognostic examinations.","PeriodicalId":8848,"journal":{"name":"Asian Pacific Journal of Cancer Biology","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77819173","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 balance of histone acetylation is determined by the activities of two groups of enzymes including histone acetyltransferases (HATs) and histone deacetylases (HDACs). Histone deacetylation is generally associated with silencing gene expression resulting in several solid tumors. HDAC inhibitors (HDACIs) are the new class of potential anticancer compounds for the treatment of the solid and hematological cancers. The current study was designed to evaluate the effect of trichostatin A (TSA) on histone deacetylases 1, 2 and 3, p21Cip1/Waf1/Sdi1 (p21), p27Kip1 (p27), and p57Kip2 (p57) gene expression in breast cancer SK-BR-3 cell line. Materials and Methods: The breast cancer SK-BR-3 line was treated with TSA. To determine cell viability, cell apoptosis, and the relative expression level of the genes, MTT assay, cell apoptosis assay, and qRT-PCR were done respectively. Results: TSA significantly inhibited cell growth, and induced apoptosis. Furthermore, this compound increased p21, p27, and p57 and decreased histone deacetylases 1, 2 and 3 gene expression significantly. Conclusion: The TSA can reactivate the p21, p27, and p57 through down-regulation of histone deacetylases 1, 2 and 3 gene expression.","PeriodicalId":8848,"journal":{"name":"Asian Pacific Journal of Cancer Biology","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88958214","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}

Anticancer potential of silver and silver metal compounds is investigated in these days. A study on the in vitro interactions of silver nitrate (AgNO3) with MCF7 human breast carcinoma cells was performed to detect cytotoxic effects which induce apoptotic pathways.Materials and Methods: The cytotoxicity of silver nitrate which administered on MCF7 cells was assessed by MTT assay. The apoptotic influences of silver nitrate (IC50: inhibition concentration) were determined using Annexin V-FITC/PI, JC-1, TUNEL paraffin embedded and confocal microscopy assays. Silver nitrate induced cytotoxicity and apoptosis in MCF7 cells. Results: In this work, we demonstrated that the inhibition of cell growth which is time and dose dependent in MCF7 cells for 24, 48 and 72 hours. The inhibition concentration of silver nitrate (IC50) was found as 10 µM in MCF7 cells for 72 hrs. The early/late apoptotic and necrotic changes which occured with silver nitrate (IC50: 10µM) administered, were analyzed in the MCF7 cells for 72 hrs. However, the reduced mitochondrial membrane activity (ΔΨmt) was observed by silver nitrate-treated (IC50: 10µM) in the MCF7 cells for 72 hrs. In addition to these findings, a variety of apoptotic structures were demonstrated on MCF7 cells for 72 hrs.

In addition, changes in DNA methylation pattern have seen in many diseases, including cancer. Analysis of DNA methylation has been useful for rapid disease diagnosis and progression. In recent decades, a revolution has taken place in the methods of DNA methylation analysis, and it is possible to study the pattern of gene methylation at a widespread, short and high resolution level. These methods can be divided into three general categories: (1) cut-based methods by methylation-sensitive enzymes; (2) sodium bisulfide based methods; (3) antibody based methods.
