Pancreatic cancer in the MENA region, a bibliometric review

Pancreatic cancer in Saudi Arabia (2005-2020): increasing trend

Pancreatic cancer, a highly fatal malignancy, has shown a global rise in the incidence and mortality rates. However, these rates vary significantly across different regions worldwide. This study aims to assess the incidence and mortality of pancreatic cancer in Saudi Arabia. We collected the data from 16 annual cancer incidence reports in Saudi Arabia for the study period (2005-2020) and from the WHO's IARC Global Cancer Observatory website. Although the burden of pancreatic cancer in Saudi Arabia is relatively lower compared to global rates, the disease incidence has shown a steady increase over the study period, in addition to regional variations within the country. The disease predominantly affects the elderly population, aged 50 years and above in both genders, with males exhibiting higher rates than females. Further studies are required to identify the potential risk factors for pancreatic cancer in the Saudi population.

Pancreatic cancer: experience from an emerging country in North Africa

PURPOSE

Pancreatic cancer is a major global health problem, it's a highly aggressive and often has a poor prognosis. The aim of this work is to carry out a retrospective epidemiological study on pancreatic cancer in a university hospital in a North African country.

METHODS

This is a monocentric, descriptive and analytical retrospective cohort study carried out in the Gastroenterology department of the Mohammed VI University Hospital of Oujda, Morocco, between January 2018 and December 2022. Analysis were performed using IBM SPSS Version 21.0 RESULTS: During this period, 197 cases of pancreatic cancers were collected, the median age was 64.6 years, the majority of patients (90.9%) were over 50 year's old. and there was no significant difference in gender distribution. Among the patients, several risk factors were prevalent, including chronic tobacco smoking (22.8%), alcohol consumption (12.7%), diabetes (38.1%), obesity (7.6%), and a family history of pancreatic cancer (3%). The most common symptoms at presentation were abdominal pain and obstructive jaundice. Imaging revealed that the majority of cases were located in the head of the pancreas (80.7%). Only 19.8% of the cancers were diagnosed at a resectable stage and adenocarcinoma was the predominant histological type (96.4%). Patients with advanced cancer stages showed higher levels of CA 19-9 and hypoalbuminemia.

CONCLUSION

Our study aligns with previous research, indicating an increased incidence of pancreatic cancer among elderly individuals, particularly those with several risk factors such as chronic tobacco smoking, alcohol consumption, diabetes. A small proportion of cancer cases are deemed resectable at the time of diagnosis.

The burden of pancreatic cancer and its attributable risk factors in the Middle East and North Africa region, 1990-2019

BACKGROUND AND AIM

Globally, pancreatic cancer is recognized as one of the most lethal types of cancers. We report the burden of pancreatic cancer and its attributable risk factors in the Middle East and North Africa (MENA) region, from 1990 to 2019, by age, sex, and socio-demographic index.

METHODS

Publicly available data from the Global Burden of Disease 2019 study were used to report the incidence, deaths, and disability-adjusted life years (DALYs) attributable to pancreatic cancer, as counts and age-standardized rates with 95% uncertainty intervals.

RESULTS

In 2019, pancreatic cancer had an age-standardized incidence rate of 5.3 and a death rate of 5.5 (per 100 000) in MENA, which have increased by 97.5% and 93.4%, respectively, since 1990. There were 563.6 thousand DALYs attributable to pancreatic cancer in 2019, with an age-standardized DALY rate of 123.0, which has increased by 84.9% since 1990. The highest number of incident cases was found in the 60-64 and 65-69 age groups, among male and female, respectively. In addition, the MENA/global DALY ratios were higher in all age groups for both sexes in 2019, than they were in 1990. There was a positive association between socio-demographic index and the burden of pancreatic cancer. Smoking, high fasting plasma glucose, and high body mass index were responsible for 19.2%, 9.3%, and 9.3% of the attributable DALYs in 2019, respectively.

CONCLUSIONS

There was a clear and substantial increase in the burden of pancreatic cancer in the MENA region. Prevention programs should be implemented in the region that target these three risk factors.

The state of cancer research in fragile and conflict-affected settings in the Middle East and North Africa Region: A bibliometric analysis

Background

Cancer represents a disproportionate burden in LMICs, especially conflict-affected countries in the MENA region. Research output on cancer fails to match the growing burden in the region. This bibliometric study aims to examine the status and trends of cancer research in fragile and conflict-affected settings in the MENA region from 2000 to 2021, while also incorporating economic and demographic indicators as additional factors of analysis.

Methods

The Web of Science databases were searched for publications related to cancer research in Iraq, Lebanon, Libya, Palestine, Syria, and Yemen from January 1, 2000, to December 31, 2021. The retrieved publications were screened based on preset eligibility criteria and the final list was analyzed using the Bibliometrix Package in R to generate the annual scientific production and citations, journals, institutions, authors, collaborations, keywords, and title co-occurrence. Each country's annual scientific production was analyzed against its annual GDP per capita.

Results

A total of 4,280 documents met the inclusion criteria in this research. The annual number of publications revealed a significant increase over the past 20 years. These publications were mostly published in international journals that had impact factors rated in the 3rd or 4th quartiles. The overall contribution of researchers from Fragile and Conflict-Affected Settings (FCS) to cancer research was 6.5% of the MENA cancer research productivity, despite comprising around 23% of the total MENA region's population. Lebanon had the highest publication productivity at the country level, followed by Iraq and Syria. GDP per capita was not significantly correlated with cancer research across the countries under investigation. At the institutional level, the American University of Beirut was the most prolific institution and had the highest number of collaborations and the widest range of cooperative partners. Most first authors were male researchers. There is an interest in cancer expression, prevalence, diagnosis, and management in terms of commonly researched topics.

Conclusion

This study underscores the need for a concerted effort to improve cancer research outcomes in FCS, which can be achieved through targeted research, increased investment in research infrastructure and capacity-building initiatives, and greater regional and global collaboration.

Emerging current trends and research focus related to pancreatic cancer metabolism: A bibliometric and visualized analysis

Background

As a malignant digestive system tumor, pancreatic cancer has unique metabolic characteristics. In recent years, the study of pancreatic cancer metabolism is in full swing, which provides a new direction for the treatment of pancreatic cancer patients. However, there is no systematic report of pancreatic cancer metabolism. In this paper, bibliometrics and visualization methods were used to analyze the number of publications, countries/regions, authors, institutions, journals, co-cited references, and keywords of pancreatic cancer metabolism articles, to summarize the research trends and predict research hotspots.

Methods

We searched, screened and downloaded articles on pancreatic cancer metabolism through the Web of Science Core Collection (WoSCC). Using CiteSpace, VOSviewer and Bibliometrix Package to analyze publications, countries/regions, authors, institutions, journals, co-cited references, and keywords of pancreatic cancer metabolism to identify research trends and predict research hotspots.

Results

According to the inclusion and exclusion criteria, a total of 5,255 articles were retrieved during the period 1943-2022. The number of publications on pancreatic cancer metabolism is increasing year by year. The United States (n=1602, 30.49%), China (n=1074, 20.44%), and Italy (n=313, 5.96%) are the three countries with the largest number of publications and citations, and there is close cooperation between countries. LI J (n=55) is the most prolific author. FUDAN UNIV (n=348) is the most published institution. CANCERS (n=118), PLOS ONE (n=93), and CANCER RESEARCH (n=80) are the most popular journals in this field. "Nutriment-deficient environment", "cancer chemoprevention" and "targeting cancer stem cell" are the main areas of focus. "immunotherapy", "ferroptosis" and "targeted therapy" are hot keywords in recent years. Taking pancreatic cancer metabolism as an entry point to study the role of traditional Chinese medicine (TCM) mainly focuses on curcumin and resveratrol, lack of broader and deeper research on TCM.

Conclusions

The number of publications on pancreatic cancer metabolism has generally increased, and scholars have generally paid more attention to this field. "immunotherapy", "ferroptosis" and "targeted therapy" are the current research hotspots. The in-depth study of pancreatic cancer metabolism will provide new ideas for the treatment of pancreatic cancer.

Bibliometric and Visualization Analysis of the Ecology of Men's Sexual and Reproductive Healthcare Research in MENA (1985-2022): Outputs, Trends, Shortcomings and Hotspots

Background

To date, no previous research assessed the bibliometrics of men's sexual and reproductive healthcare (SRHC) across Arab countries. This study appraised the current standing of men's SRHC research in the MENA (Middle East and North Africa) region.

Methods

We performed a bibliometric analysis to assess qualitatively and quantitatively the peer-reviewed articles published from Arab countries from inception to 2022. In addition, we conducted a visualization analysis, and assessed outputs, trends, shortcomings and hotspots over the given time period.

Results

There was a generally low numbers of publications, 98 studies were identified, all with cross-sectional design, and two thirds explored prevention and control of HIV/other STDs. Studies were published in 71 journals, of which the Eastern Mediterranean Health Journal, Journal of Egyptian Public Health Association, AIDS Care and BMC public health were most common. The Journal of Adolescent Health, Fertility Sterility and Journal of Cancer Survivorship were among the highest IF ranking. Publishers were commonly USA or UK-based, median journal IF was 2.09, and five articles were in journals of IF > 4. Saudi Arabia had the highest published output followed by Egypt, Jordan and Lebanon, while 10 Arab countries had no publications on the topic. Corresponding authors expertise fields were most commonly public health, infectious diseases and family medicine). Collaborations in-between MENA countries were notably low.

Conclusions

There is general paucity of published outputs on SRHC. More research across MENA is needed, with more inter-MENA collaborations, and with inclusion of countries that currently have no outputs on SRHC. In order to accomplish such goals, R&D funding and capacity building are required. Research and published outputs should address SRHC burdens.
