The concentration of the drug was selected individually by means of peripheral blood cells aggregation data on the “Plasmon-6” biosensor. The criterion for the drug concentration selecting was the lowest level of peripheral blood cells aggregation in vitro, reflecting the level of NMDA-dependent calcium channels blocking of the peripheral blood cells membranes.

Besides inherited genetic disorders, a diverse range of physical, chemical and biological agents may induce cancer. About 15-20% of cancers are known to be originated due to pathogens. Viruses are considered to be the second (after smoking) most important risk factor in inducing human cancer. Viruses may either harbour a copy of oncogene or have an ability to alter the expression of cellular copy of the oncogenes. Both RNA and DNA viruses are can induce oncogenesis. Most of the DNA tumour viruses either integrate their genome (complete or part of it) into the host genome or express early genes that are required for early event of virus replication. These early genes are responsible for oncogenic transformation of host cells. Based upon the mechanism involved, oncogenic RNA viruses are divided into two groups-transforming and non-transforming RNA viruses. Transforming RNA viruses carry viral oncogenes that are homologous to the host oncogene, their expression in infected cells results in oncogenic transformation of the cell. Non-transforming RNA viruses induce oncogenesis similar to the DNA viruses. Contrary, oncolytic viruses selectively replicate in cancerous cells and induce cell death without any damage to the normal tissues. Typically, oncolytic viruses are nonpathogenic to humans that can naturally replicate in cancer cells by exploiting oncogenic cell signalling pathways. Pathogenic viruses can also be genetically manipulated which allow them to replicate in cancerous but not in normal cells. This review review describes the molecular mechanisms associated with virus induced oncogenesis and oncolysis.","PeriodicalId":9422,"journal":{"name":"Cancer Research Journal","volume":"85 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80946879","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}

Most of the differentiated thyroid cancers are asymptomatic. Surgery is the mainstay of management to be followed by radioactive iodine (RAI).

The aim of this study was to determine factors affecting the clinical outcome of patients with differentiated thyroid cancer (DTC) following RAI treatment in a resource limited setting. Methods: This was a prospective cohort study carried out from 2014 to 2018 at the Ocean Road Cancer Institute, in Tanzania. A total of 52 histologically proven differentiated thyroid cancer patients post- near or total thyroidectomy were recruited. All patients received RAI therapy until ablation was achieved, were maintained on thyroxine suppression dose, and were followed for two years. Results: A total of 52 differentiated thyroid cancer patients were recruited after surgery by convenience sampling. The median age of patients was 46 years (range 17-77), and 87% (n=45) were female. Distant metastases were detected in 60% of patients (n=20) at initial presentation. The most common clinical presentation was a neck mass without compression symptoms (85%). Analysis at the end of two years revealed that female gender, clinical-pathological presentation, and the absence of distant metastasis(es) at diagnosis and amount of RAI received, contributed significantly to improved outcome. Conclusion: In a limited resource setting, the outcome of DTC patients post RAI therapy can be improved by early diagnosis hence improving clinical outcome.","PeriodicalId":9422,"journal":{"name":"Cancer Research Journal","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80069722","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}

Advanced neurosurgical techniques such as neuroendoscopy and frameless stereotactic biopsy have made diagnosis of newly discovered cases of ICGCTs easier and safer. Material and methods: Seventeen patients with intracranial germ cell tumors operated upon between 2008 to 2012 at the Children's Cancer Hospital Egypt, were retrospectively reviewed and analyzed regarding the surgical decision, clinical outcome and surgical complications. Results: There were 9 cases of germinoma (53%), and 8 cases of non-germinomatous germ cell tumors (47%). Nine cases were in the pineal region, six in the suprasellar, and two in the thalamic region. Ten cases were operated upon initially by open surgery and frozen section with subtotal resection and seven cases were biopsied either endoscopically (3 cases) or by frameless guided stereotaxic (4 cases). Accurate pathology was achieved in all biopsied cases without major complications. In the germinoma group, the 4-year overall survival and progression free survival rate were 75% for both at a median follow up period of 26 (range 1 -50) months. For the non-germinomatous germ cell tumors group, the 4-year OS and PFS rates were 36.5% and 31.2% at a median follow up period of 11 (range 2-54) months, respectively. Conclusion: In cases of intracranial germ cell tumors with negative tumor markers the role of surgery is important in the establishment of proper histopathological diagnosis. However, in Non Germinomatous Germ Cell Tumors, further investigations should be done regarding the extent of resection owing to the poor long-term outcome.","PeriodicalId":9422,"journal":{"name":"Cancer Research Journal","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74434126","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}
