Whether PET-CT and CT were able to exclude N2 or N3 disease was the subject of evaluation of this study. \u0000Results: It was found at the end of the study that PET-CT was able to exclude N2 and N3 involvement in 92,9 % of the cases, whereas CT alone could do the same exclusion in 93,6 %. \u0000Conclusion: PET-CT and CT can well exclude N2 and N3 disease in patients with breast cancer. It may be suggested that PET-CT can replace sentinel lymph node biopsy in future preoperative evaluations.","PeriodicalId":73658,"journal":{"name":"Journal of clinical & experimental oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46933335","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}

Mizan","doi":"10.4172/2324-9110.1000211","DOIUrl":"https://doi.org/10.4172/2324-9110.1000211","url":null,"abstract":"Introduction: Leptin, the hormone secreted from white adipose tissue is suspected of being a causative factor in tumorigenesis in various tissues. Thus it might be a link between obesity and breast cancer. \u0000Objectives: In this project we tried to study causative association of obesity and serum leptin with invasive ductal breast cancer (IDC) in a sample of Malaysian population. \u0000Methods: We measured various obesity parameters, and estimated serum leptin levels in a group of healthy control and IDC patients. After confirming diagnosis by standard histopathological methods, serum leptin levels were estimated using ELISA. Both the pre-and postoperative leptin levels were measured with the Patient group. \u0000Results: The difference between the serum leptin levels of the Control and the Patient group were highly significant with a P value of 0.05). \u0000Conclusion: Since high serum leptin in IDC patients persists unabated in the post-operative state, we infer that the source of leptin in these cases cannot be the breast cancer tissue itself and leptin cannot be a marker for breast cancer. Highly significant association between serum leptin and IDC patients suggests that leptin in serum might play a causative role in the tumorigenesis of breast cancer, and it might be an important connection between obesity and breast cancer. Therefore, leptin signal transduction pathway might be a prospective therapeutic target in the treatment and prevention of IDC.","PeriodicalId":73658,"journal":{"name":"Journal of clinical & experimental oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46630756","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}

Lb","doi":"10.4172/2324-9110.1000E112","DOIUrl":"https://doi.org/10.4172/2324-9110.1000E112","url":null,"abstract":"Our group has been pioneering in exploring that the pharmacological handling of Ca2+/cAMP signalling interaction could be a better therapeutic method for increasing neurotransmission in psychiatric disorders, and stimulating neuroprotection for combating neurodegenerative diseases, such as Alzheimer´s disease. Indeed, Ca2+ is a classic intracellular second messenger, now well recognized as a ubiquitous molecule that controls several processes, including gene transcription, cell cycle regulation, mobility, apoptosis, neurotransmitter release and muscle contraction. In addition, cAMP, another vital intracellular messenger, modulates since cardiac contraction to neurotransmitter release. Do these intracellular messengers ´work´ independently? Of course not, and we demonstrated it! Through groundbreaking experiments (including one by accident!), our group discovered that the paradoxical effects (e.g. reduction of intracellular Ca2+ concentration, and enhancing of neurotransmitter release?!) produced by L-type Ca2+ channel blockers (CCBs) resulted from interferences on the Ca2+/ cAMP signalling interaction. Considering the widely use of CCBs as antihypertensive drugs, and for combating arrhythmia, the elucidation of these paradoxical effects proved to be very important (specially for clinical reasons). How does this history correlate to cancer field? Considering the notion that Ca2+/cAMP signalling interaction is a fundamental cellular process, which exists in many cell types, whether this interaction may be a novel therapeutic target to alter cancer tumor growth, angiogenesis and metastasis, without affecting normal cell physiology deserves special consideration. Thus, this editorial article highlights the latest advances made by our group in the field of Ca2+/cAMP signalling interaction.","PeriodicalId":73658,"journal":{"name":"Journal of clinical & experimental oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46375649","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 most important thing is to do HPV-DNA analysis with Pap smear. The aim in this study is to perform a detailed follow-up program according to the results of patients who had been diagnosed with cervical intraepithelial lesion (SIL) who applied to the hospital for 2 years and to find out whether being used HPV-DNA results affected the SIL lesions without applying a smear test (pap test) in the menopausal patients with negative HPV-DNA analysis by performing only HPVDNA analysis. \u0000Materials and Methods: A smear test was requested for 11,850 patients aged 50 ± 3.2 in the Zekai Tahir Burak Women’s Health Training and Research Hospital between the years 2015-2016 for a 2-year period. 5180 patients are menopausal. HPV-DNA genotyping analyzes were performed for HPV 16,18,31,33,35,3 9,45,51,56,58,66 and 68 types while 1102 of these patients were followed by pap test for Low grade SIL, and colposcopies were performed and biopsies were taken by the same gynecologist. In this study, Chi-square test, Mann Whitney U test were used for the statistical analysis and Spearman Rho test was used for correlation analysis with IBM SPSS statistical program version 21.0. Values of p ≤ 0.001 were considered significant. Non-significant analyzes were not used in this study. \u0000In the result of histopathological examination, cases were compared with smear findings. For colposcopy, Barcelona 2002 colposcopy terminology was used. In the histopathologic analysis of colposcopic biopsies, Bethesda System 2014 version and also HPV ascia LAST in ano-genital lesion coexistence were used for classification. \u0000Findings: Patients were selected among 11,850 patients who applied to the hospital between 2015 and 2016 and were received cervical cytology specimens. 5180 patients were in menopausal period. 1102 of these patients have LSIL. 278 of the LSIL 1102 patients were reported as HPV (+) CIN I neoplasia and the remaining 824 patients as HPV (-) non-neoplastic lesion. CIN I lesion in 270 patients and CIN II lesion in 8 were determined with colposcopic biopsy performed in HPV-DNA (+) group (n=278). CIN I lesion in 670 patients and CIN II in 14 patients were also found with colposcopic biopsy performed in HPV-DNA (-) group (n=840); in 140 patients dysplasia was not observed. \u0000We think that only HPV-DNA analysis is not appropriate for menopausal HPV (+), pap smear negative patients with negative","PeriodicalId":73658,"journal":{"name":"Journal of clinical & experimental oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48841497","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}
