Oral cancer is one of the most prevalent cancers in India but the underlying mechanisms are minimally unraveled. Cancer research has immensely benefited from genome scale high throughput studies which have contributed to expanding the volume of data. Such datasets also exist for oral cancer genes but there has been no consolidated approach to integrate the data to reveal meaningful biological information. OrCanome is one of the largest and comprehensive, user-friendly databases of oral cancer. It features a compilation of over 900 genes dysregulated in oral cancer and provides detailed annotations of the genes, transcripts and proteins along with additional information encompassing expression, inhibitors, epitopes and pathways. The resource has been envisioned as a one-stop solution for genomic, transcriptomic and proteomic annotation of these genes and the integrated approach will facilitate the identification of potential biomarkers and therapeutic targets.

Breast cancer accounts for about 26% of all newly diagnosed cancers in women aged 20 to 59 years. As part of a basic program for cancer control, the present cross sectional descriptive study was conducted with the objective of determining the epidemiology of breast cancer in Ardabil province during 2003-2010. Necessary information on 469 recorded cases of breast cancer in the registry were collected by check list from patient's files and then analyzed by statistical methods with SPSS.16 software. Some 455 of the patients (97%) were female, 329 (70.1%) residing in Ardabil. The mean age was $46.8{\pm}13.6$ and most were in the age group of 40 - 60. The most prevalent pathologic form was infiltrative ductal carcinoma with 316 cases (67.4%), the largest proportion being grade II (30.6%), but very many belonged to grades III and IV (40.5%). Breast cancer in Ardabil province appeared to slightly increase over the period studied. The results were similar to other places in Asia. With regard to this, more widespread studies are required to determine factors influencing the prevalence at low age and also how to promote early detection.

Hepatocellular carcinoma (HCC) is one of the most prevalent malignant diseases worldwide and a leading cause for death in Asia, where the major risk factors are chronic hepatitis B virus and hepatitis C virus infection. Because most HCC patients die within 3 to 6 months from the time of diagnosis, searching for a new treatment has become more urgent for HCC than other cancers because there is no existing effective systematic therapy. In Korea and Asia, traditional herbal medicine is frequently administered to patients with advanced HCC. We present a HCC case where complete regression was observed after taking herbal medicine. Since the specific mechanism is unknown, we cannot determine whether the herbal preparation had a direct effect on the regression of HCC. Nevertheless, this case provides us a reason and hope for further research.

Rates based on age-adjusted incidence of colorectal cancers over a 10-year period in Kerman, the biggest province of Iran, were estimated from 2003 to 2013. Data were obtained from the population-based cancer registry unit of Kerman University of Medical Sciences (CR-KMU). Information included age, sex, city, ICD-O and year of registry. Our trend analyses cover 3.91% of the Iranian population. The data set comprised cases diagnosed from 2003 to 2013.The population of over 20 years was interpolated using 2003 and 2010 censuses. Then, truncated age-adjusted incidence rates were calculated. Increase was noted from 2003-2009 to 2010-2013 for 731 cancer cases considered in the analysis. The increases was most prominent in 2009. Totally, the frequency of the cancer was greater in males. Moreover, calculating truncated age-adjusted incidence rate indicated that the most prevalent age of colorectal incidence was in the 50-59 year age group except in 2007-2008 and 2012- 2013, when greatest incidences occurred in people aged 60-69 years. Our data revealed that the incidence rates of colorectal cancer have increased over the past decade in our region of Iran.

Gastric cancer is prevalent in Korea and ranked as the third most common cancer in 2019, followed by lung and thyroid cancers. The National Cancer Screening Program (NCSP) for gastric cancer has been implemented in adults aged ≥ 40 since 1999 and involves endoscopic screening every 2 years. The beneficial effects of the current NCSP on early cancer detection, cost-effectiveness, and mortality reduction are evident. However, the screening program results in a large socioeconomic burden and the consumption of medical resources, as it focuses solely on secondary prevention (early detection) rather than primary prevention of cancer. Helicobacter pylori is defined as a group I carcinogen by the International Agency for Research on Cancer. Hence, its eradication has been suggested as an important primary gastric cancer prevention strategy. Well-designed randomized controlled trials involving high-risk groups (post-endoscopic resection of early gastric cancer and family history of gastric cancer) and long-term follow-up studies in the general population have provided high-quality evidence regarding the effects of H. pylori eradication on gastric cancer prevention. In this review, we discussed the evidences for a possible modification of the current gastric cancer secondary prevention strategy by introducing primary prevention through H. pylori eradication. Areas for future research to optimize primary prevention strategies were also suggested.

Female breast cancer is the fifth highest cause of mortality. Breast cancer is the most prevalent type of cancer in women globally, while it can also affect men. STAT5A plays a role in its development and progression. Given that activation of STAT5a is frequently linked to the growth and progression of tumors, STAT5a has been identified as a possible target for the therapy of several cancers. STAT5A, in particular, has proven to be overexpressed in various breast cancer cell lines and tumors, and it has been associated to the promotion of tumour cell proliferation and survival. STAT5A inhibition has been shown in vitro and in vivo to reduce the development of breast cancer cells. As a result, we have screened compounds from the FDA database that might serve as potential inhibitors of STAT5a through virtual screening, docking, DFT and MD simulation approaches. The drug Nilotinib has shown promising results inhibiting STAT5a. Further, in-vitro analysis will be carried forward to understand the anti-cancer activity.

Ultra-processed foods, falling under group 4 of the Nova classification system, are manufactured from processed food ingredients such as oils, fats, sugars, starch, and protein isolates, containing minimal to no whole food. They commonly incorporate flavorings, colorings, emulsifiers, and various cosmetic additives to enhance their palatability. Ultra-processed foods have become increasingly prevalent in contemporary society owing to their convenience, affordability, extended shelf life, and enhanced taste and aroma through additives. This surge in the consumption of ultra-processed foods has sparked discussions regarding its adverse health effects. Numerous studies have highlighted that an increased intake of ultra-processed foods elevates the risk of metabolic disorders, such as cardiovascular diseases, obesity, and diabetes, along with an increased risk of various cancers. Moreover, its association with an increased mortality risk underscores the importance of recognizing that opting for these foods based solely on taste and convenience is risky. Thus, by recognizing dietary habits as modifiable factors that can prevent health issues, maintaining a balanced diet with diverse nutrient intakes is crucial for overall health. Therefore, raising awareness and understanding of ultra-processed food consumption can significantly contribute to promoting healthy lifestyles.

Colorectal cancer (CRC) is one of the most prevalent cancers and is the leading cause of cancer-related mortality worldwide. Based on the current screening guidelines by the American Cancer Society and Korean multi-society expert committee, CRC screening is recommended in asymptomatic adults starting at the age of 45 years. Fecal immunochemical test-based screening programs reduce the development of CRC and related mortality in the general population. However, this most popular CRC screening strategy demonstrates a crucial limitation due to modest diagnostic accuracy. Colonoscopy may be considered as an alternative primary method for CRC screening; however, its implementation can still be challenging due to concerns regarding invasiveness, low adherence, cost-effectiveness, and quality assurance. To overcome the limitations of current screening tests, innovative noninvasive tests for CRC screening have been developed with advances in molecular biology, genetics, epigenetics, and microbiomics for detecting CRC, which may enhance the approach to CRC screening and diagnosis in clinical practice in the near future. This review explores the emerging screening methods and discusses their potential for integration into current practice.

Background: Oral cancer is one of the most prevalent cancers and one of the top ten causes of death in the whole world. Most oral cancers are diagnosed at late stages. Since dentists play a critical role in early detection of oral cancer, they should be knowledgeable and skillful in oral cancer diagnosis. The aim of this study was to survey dentist knowledge about oral cancer in Southern Khorasan Province. Materials and Methods: This descriptive, cross-sectional study was conducted with dentists who participated in an in-service educational program at the Faculty of Dentistry of Birjand University of Medical Sciences in spring 2014. A questionnaire including demographic information with 11 questions regarding oral cancer was prepared. The participants were required to be complete the questionnaires within a specific time span. The data were analyzed using SPSS 15 software by t-test and one-way ANOVA at 0.05 confidence level. Results: A total of 73 dentists out of 80 answered the questionnaires - 36 (49.3%) were females and 37 (50.7%) were males. Total mean score of knowledge was $7.91{\pm}1$ of 11. Mean scores of knowledge of male and female participants were $7.70{\pm}1.83$ and $8.13{\pm}1.94$ respectively. Mean knowledge score of general dentists was $7.41{\pm}1.79$ and of dental specialists was $9.44{\pm}1.0$ In spite of higher knowledge score of women compared to men and general dentists compared to dental specialists, these differences were not statistically significant (p=0.09). Tukey testing showed a significant difference between groups with 1-4 years of experience (8.74) and over twenty years of experience (6.50) ( p=0.001). Conclusions: Considering the good knowledge level of young dentists and the specialists and the importance of early diagnosis of oral cancer, it seems necessary to pay more attention to academic education for dentistry students, as well as holding retraining courses for experienced dentists, so that their knowledge not be reduced over time.

Background: Leukemia and lymphoma demonstrate significantly incidence rates throughout the world and particularly in Iran they cause serious mortality and diagnosis and treatment expenditures for both families and the health system. Combined they account for about 11 percent of cancers in Mazandaran province, ranking number 2 in prevalent cancers. The purpose of this study was to provide a first general and specific description of leukemia and lymphoma in Mazandaran province. Materials and Methods: In this descriptive retrospective study, entire patient's data were reviewed which had confirmed diagnosis of leukemia and lymphoma with valid laboratory or pathology reports in the period 2001-2008. The data were collected by Babol health research site related to Tehran University of Medical Science. Incidence rates based on age groups, gender, city of residence and type of malignancy were calculated and analyzed. Results: In Mazandaran province, 1,146 cases of leukemia and lymphoma were encountered, 5.9 in 100,000 persons on average annually. The highest incidence rates were obtained at age of 70 or above (26.4) and the lowest at age of 0-9 (2.3).The incidence rates in males and females were 7.1 and 4.8 respectively with a ratio of 1.5. The highest incidence rate was in Babol (7.3) and the lowest was calculated in Neka and Tonekabon equally (1.5). According to the type of malignancy, non Hodgkin lymphoma, with 2.5/100,000 have the most incidence rate and myeloid leukemia with 1.8 had the lowest. Conclusions: The obtained findings indicate clear differences in incidence rates based on age, gender, residence, and type of malignancy. Therefore it's suggested that in addition to promote data collecting programs, research projects should be programmed to define leukemia and lymphoma risk factors in this province.
