The World Health Organization registered 600,000 cases of death due to breast cancer in 2021 and estimated that there would be 1 in every 8 women diagnosed with breast cancer in the next 10 years. Studies have discovered the role of proteins in the pathways that affect breast cancer but have not found a potential biomarker effective for all types, especially for triple-negative breast cancer. It remains a challenge to detect and treat breast cancer, especially if found in the later uncurable stage. With this, proteomics becomes a practical approach to screening new protein biomarkers for breast cancer diagnosis, therapy, and disease control. Proteomics covers the study of the entire protein, and its modification has been leading the race in breast cancer biomarker discovery made possible through the advancement of mass spectrometry and various bioinformatics tools. The combination has brought novel information being the fastest yet simplest approach for deep, comprehensive, and high throughput approach. This review article will give an overview of these trending online tools for proteomics research while citing examples of their utility with known clinical breast cancer biomarkers.","PeriodicalId":8848,"journal":{"name":"Asian Pacific Journal of Cancer Biology","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90657890","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}

Much research has concentrated on attempts to identify major carcinogenic influences, and failure to do so has made it clear that the problem in high incidence areas (HIAs) is not primarily of potent environmental carcinogens, but of population susceptibility. In Africa the association with maize is constant and strong. Research in the last decade has helped to explain that association. Considered along with historical findings there is now enough evidence to establish causal associations of a nutritionally deficient maize diet and use of maize meal with squamous cancer of the esophagus. Evidence is available in a high incidence area of degenerating maize meal resulting in excess production of PGE2, gastric hypochlorhydria and a predominant pattern of non-acid gastroesophageal reflux. This pathway explains the existence of major population susceptibility: a poor maize-based diet provides specific nutritional deficiencies and n-6 fatty acid dominance which cause failure of homeostasis of the arachidonic acid cascade; with this background chemically degenerating maize meal then triggers duodenogastric reflux and non-acid gastro-esophageal reflux; non-acid reflux causes squamous cancer of the esophagus. Within a susceptible population, environmental carcinogens including tobacco increase individual risk. There is sufficient evidence that this is an active pathway, and the dominant pathway to SCCE in high incidence areas in Africa.There is sufficient evidence to justify appropriate preventative measures.","PeriodicalId":8848,"journal":{"name":"Asian Pacific Journal of Cancer Biology","volume":"79 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84974155","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}

Methods: A Randomised controlled Trial was conducted in AIIMS Rishikesh over a period of one year (2020-2021). All women presenting to OPD in age group 25-60 years were screened with PAP smear and per speculum examination, and women with Abnormal PAP smear or clinically unhealthy cervix were subjected to colposcopy. Reid and Swede scores were calculated and colposcopy guided biopsy taken. Women with CIN2/3 on either of the colposcopy scores were randomized to two or three step approach. Women falling into two step approach (group A) underwent LEEP in the same sitting while the latter group (group B) was told to follow up with histopathology reports for further management.The final histopathological diagnosis and LEEP results were compared. Results: Overtreatment rates were 22% in see and treat approach, distributed as 3.6% in HSIL + ASC_H group and 33 % in LSIL patients. None were lost to treatment in this group. 39 out of 50 women in Group B needed definitive treatment after their biopsy results and 48% of them were lost to follow up. 72% were adequately treated in group A while only 22 % could be adequately treated in Group B. Conclusion: It can thus be safely concluded that despite the risk of overtreatment, a two step approach should be considered for preventive management, especially considering the rate of loss to follow up in three step approach. This study thus advocates the use of See and Treat protocol, especially in the high-grade cytology lesions. IN low risk cases too, the study proposes that see and treat protocol can be used, albeit with good clinical judgement. Offering opportunities to reduce suffering associated with the eminently preventable cervical cancer is an ethical imperative and the SEE and TREAT approach is an attempt in that early preventive direction. ","PeriodicalId":8848,"journal":{"name":"Asian Pacific Journal of Cancer Biology","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85886913","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}

FAP is characterized by development of multiple adenomatous polyps (>100) in the colon. The aim of this study was to evaluate the prevalence of gastroduodenal polyps in FAP patients referred to the Taleghani hospital, a teaching referral center in Tehran, Iran. Materials and Methods: Front-view and side-view endoscopies were performed in 33 FAP patients. Papillary biopsies were taken for all patients. Site of polyps, their number and size, histologic findings, patient general information (gender, age and family history of FAP/colorectal cancer/gastroduodenal polyps) were collected and reported. 28 patients of the study were evaluated using upper GI endoscopy again after 5 years for changes in characteristics and probable transformation of polyps into cancer. Results: Gastric polyps were seen in 42.4 % of patients. 76.45% of the patients had fundic gland polyps and hyperplastic polyps were noticed in 39.93% of them. Duodenal adenomas were found in 30.3% of patients which were reported to be tubular adenomas with low grade dysplasia and tubulovillous adenomas with low grade dysplasia in 60% and 45% of patients, respectively. Conclusions: Findings of this study bespeak the high prevalence of gastroduodenal polyps and the presence of dysplasia in duodenal polyps among FAP patients referred to the hospital.

A 46-year-old female patient admitted to Urology Department, Sohag University, in 2015. The patient had a left loin pain, no other clinical data included in her referral sheet . Radiological findings revealed a renal mass and left radical nephrectomy was performed. Histopathological evaluation revealed a circumscribed neoplasm, formed of densely packed acini with scanty stroma. The patient was diagnosed as renal oncocytoma. On re-evaluation of the Hematoxylin and Eosin-stained slides; the nuclear features were different from those described in renal oncocytomas. So, a panel of immunohistochemical markers was performed (anti-CK7, anti-EMA, anti-Vimentin, anti-Thyroglobulin and anti-TTF1). Results: The neoplastic cells showed strong and diffuse cytoplasmic expression for Thyroglobulin and CK7 and nuclear expression for TTF1. The neoplastic cells didn’t express EMA or Vimentin. Based on the characteristic nuclear features detected by Hematoxylin and Eosin-stained slides and the obtained immunohistochemical results; the diagnosis of metastatic papillary thyroid carcinoma to the kidney was confirmed.
