Marcis Leja presents research conducted in Europe on reducing cancer-related mortality in the USA.
From November 20-21, the National Cancer Center of the USA organized the annual CISNET (Cancer Intervention and Modelling Network) consortium forum in Rockville, where Professor Leja, a leading researcher at the Faculty of Medicine and Life Sciences, presented the achievements of the GISTAR, EUROHELICAN, and TOGAS projects.
CISNET is an international network of experts for intervention modeling aimed at reducing cancer-related mortality. This type of mathematical modeling allows for the identification of the most cost-effective strategies for planning measures in the fight against cancer.
Professor M. Leja was invited to present the results achieved in one of the working groups focusing on the modeling of gastric cancer (Gastric Cancer Modeling Group), addressing the GISTAR study conducted in Latvia and its results. In his virtual presentation, M. Leja discussed not only GISTAR but also ongoing related EU-funded projects, including EUROHELICAN and TOGAS, mentioning the plans intended to be implemented in the EUCanScreen project in the field of gastric cancer prevention.
"The presentation was highly appreciated, acknowledging that studies conducted in Europe have allowed for the acquisition of data that is currently not available in the USA. The issues mentioned in the presentation could mark the beginning of expanding existing collaboration with the National Cancer Institute of the USA and initiating partnerships with other US research organizations," emphasized M. Leja.

TOGAS Achieves Significant Progress in Gastric Cancer Prevention and Outreach Efforts
At this stage, TOGAS has made measurable progress and remains on track to achieve its planned outcomes, providing valuable insights into gastric cancer prevention. Public engagement and awareness initiatives have broadened knowledge through an online presence, educational materials, and targeted newsletters, reaching approximately 4,500 subscribers and producing 11 publications, including open-access formats.
Scientific contributions consist of findings presented at conferences and initial results published in peer-reviewed journals, enhancing Europe’s knowledge base on gastric cancer. Outreach efforts included a consortium meeting with 50 members, a conference with 84 in-person attendees and 11 online participants, and an outreach meeting featuring around 40 specialists, which facilitated feedback from stakeholders and EU representatives regarding project findings and applications.
Validated methodologies were achieved through WP3 (Evaluation), confirming the reliability of pilot studies, while early results from WP4 (Pilot studies) demonstrated adaptable screening methods suitable for diverse EU settings.
As we move forward, we have identified and are addressing risks, considering potential adjustments, and remain confident in meeting the project's planned objectives within the designated timeframe.
In conclusion, we would like to remind you that the achieved results pertain to the first 18-month period of the project and do not include the subsequent conference in September 2024.

November is Gastric Cancer Awareness Month
With a 5-year survival rate of just about 25% across Europe, gastric cancer remains a serious health concern. Despite rising case numbers, there is still no organized screening program in the EU. Early detection is crucial, as late-stage diagnoses contribute to the high mortality rate.
The TOGAS Project is working to change this by developing innovative screening and prevention strategies, including Helicobacter pylori (H. pylori) elimination. These efforts aim to reduce gastric cancer mortality by 40%.
Learn about the recent advances in clinical practice from the article by Prof. Mārcis Leja, leading the TOGAS research group:

It was crucial for the European Joint Action on Cancer Screening (JA EUCanScreen) project, dedicated to strengthening cancer screening systems throughout Europe. The project's goal is to save lives by detecting cancer early. The event highlighted the project's main objective: to reduce the mortality rate from cancer by improving screening practices and promoting collaboration among European countries.
From September 24 to 27, 2024, more than 80 organizations and 200 participants from 28 European countries gathered at the University of Latvia's Science House in Riga to share insights and strategies. Project coordinators, led by Mārcis Leja from the University of Latvia's Faculty of Medicine and Life Sciences Clinical and Preventive Medicine Institute (referred to as LU KPMI), successfully organized the main sessions, ensuring a productive week in the fight against cancer.
Apostolos Vantarakis, one of the project's key leaders, emphasized, "Cancer is different in each country," pointing to the need to tailor strategies to regional contexts.
Mārcis Leja, director of LU KPMI, underscored Latvia's role: "Our biggest challenge is to successfully manage the project throughout its implementation period and achieve the project's goals on a European scale. However, with this project, we also want to make significant progress specifically in Latvia—bringing cancer control closer to the level of more developed countries by revitalizing existing breast, cervical, and colorectal cancer screening programs and preparing for the implementation of new, cost-effective, and high-quality lung, prostate, and stomach cancer screening programs, as well as developing the training center infrastructure established within the project."
Throughout the week, several significant discussions took place, including on:
● The role of innovation in cancer screening, highlighting new technological solutions such as artificial intelligence that improve early cancer detection.
● Cross-border collaboration, discussing how countries can share best practices to build stronger and more effective screening systems.
● Improving data collection and resource allocation to ensure more equitable access to cancer screening across Europe.
In a session led by one of the project leaders, Urška Ivanuš from Ljubljana (Slovenia), it was emphasized: "We will implement screening programs that will lower cancer mortality rates." Her statements align with the broader theme of the event, highlighting the necessity of systematically improving cancer screening to ensure better outcomes for citizens of various countries.
Iris Lansdorp-Vogelaar, a senior expert at ERASMUS MC and one of the project leaders, stressed the importance of screening frequency, noting: "The frequency of screening is closely related to the number of deaths from cancer. The more regularly screening is conducted, the greater the chances of saving lives."
Statistics show that timely cancer detection significantly increases survival rates, but equitable access to screening has yet to be implemented across Europe. One of EUCanScreen's goals, therefore, is to ensure more accurate data collection to improve resource allocation and expand access to screening.
As part of its mission, EUCanScreen representatives will continue to urge healthcare policymakers and representatives of medical organizations to support this essential work.

The Institute of Clinical and Preventive Medicine at the Faculty of Medicine and Life Sciences of the University of Latvia is leading an extensive cancer screening project called "EUCanScreen," involving 29 countries.
From September 24 to 27, 2024, the Institute of Clinical and Preventive Medicine at the Faculty of Medicine and Life Sciences of the University of Latvia (LU KPMI) will host the launch event for the "EUCanScreen" project. This project, which brings together 97 institutions from 29 countries, is one of the most significant initiatives of the European Commission in the field of cancer control. During the event at the LU House of Sciences, located at 3 Jelgavas Street, Riga, medical and healthcare professionals will discuss ways to improve the effectiveness of cancer screening and prevention across Europe.
In 2022, there were 2.7 million new cases of cancer diagnosed in EU countries, and Latvia is among the countries with the highest mortality rates. Thus, early cancer diagnosis is a critical challenge in Latvia. By enhancing knowledge about cancer screening and subsequently organizing and refining national cancer screening programs, public health can be significantly improved, and the number of cancer-related deaths can be reduced. Additionally, this presents an opportunity for Latvia to learn from other countries and adopt their experiences.
“The implementation of the EUCanScreen project will ensure significant progress in improving the effectiveness of cancer screening programs and harmonizing their execution among European countries. The project also provides us with a unique opportunity to strengthen collaboration between national and regional institutions on a European scale, enhancing our ability to combat cancer with a systematic and coordinated approach,” emphasizes Health Minister Hosams Abu Meri.
The goal of the "EUCanScreen" project is to promote accessible and effective screening in all European countries, including Latvia. One of the project’s priorities is to increase public awareness about the importance of early diagnosis. Another priority is to develop new screening methods for lung and stomach cancer. Therefore, in collaboration with leading health institutions in Latvia, such as the Disease Prevention and Control Center (SPKC) and Rīga Stradiņš University (RSU), current screening programs will be improved, and broader public engagement will be ensured.
The project will focus on ensuring that breast, cervical, and colorectal cancer screenings meet the quality criteria established in Europe across all EU member states, as well as on the gradual implementation of three new cancer screening programs (for stomach, prostate, and lung cancer), notes Institute Director Prof. Mārcis Leja.
The project will pay special attention to the early diagnosis of the four most common types of cancer: breast, cervical, colorectal, and prostate cancer.
The project "Implementation of cancer screening programmes (EUCanScreen)," LU registration No. ZD2024/21709, is funded by the European Union's EU4Health program, Grant Agreement No. 101162959.

Researchers involved in the GISTAR study, including Professor Mārcis Leja, Inese Poļaka, Danute Ražuka-Ebela from the University of Latvia’s Faculty of Medicine and Life Sciences, Jin Young Park from the International Agency for Research on Cancer (World Health Organization), and GISTAR project coordinator Līga Krauze, also participated in the meeting.
GISTAR is a multicenter randomized study aimed at reducing mortality from gastric cancer through Helicobacter pylori (H. pylori) eradication and pepsinogen level determination. It seeks to discover new strategies to reduce gastric cancer mortality in high-risk areas. The study, which is conducted exclusively in Latvia, is led by the University of Latvia's Institute of Clinical and Preventive Medicine.
During the meeting, the GISTAR study's Data and Safety Monitoring Board praised the team's efforts to date, highlighting their successful focus on patient interests, safety, and privacy. The board also recommended the continuation of monitoring for enrolled participants as planned.
The GISTAR study is not only unique to Latvia but also to Europe, and it has gained international recognition. Some participants in the GISTAR study received a treatment course to eradicate H. pylori, and now breath tests are being conducted at study centers to determine the treatment’s success. Blood samples were taken from all participants, and various inflammation and metabolism-related parameters will be determined in the near future. These analyses will also be performed on samples collected five to eleven years ago, which are stored frozen in the laboratory. The old and new test results will be compared to investigate whether there is any connection between blood test changes and health events related to the use of H. pylori eradication medications. Additionally, the study will evaluate whether there are any correlations with untreated H. pylori infections.
Participant recruitment for the GISTAR study began in October 2013 and continued until August 2023, with a total of 11,223 participants enrolled. Follow-ups began in March 2023 and will continue until February 2026 as part of the European Union-supported EUROHELICAN and TOGAS projects.
Since spring 2023, study centers in Ludza, Alūksne, Cēsis, and Saldus have been operating, inviting GISTAR participants who were included in the study from 2013 to 2015 for follow-up assessments. Currently, the center in Rēzekne is still operating, and a new center opened in Madona on September 5. Over 2,000 participants have attended follow-up appointments so far. At present, extensive work is underway analyzing the data collected.

Where Are We with Stomach Cancer Screening in Europe in 2024?
The leading gastroenterology journal Gut* has published an article by Professor Mārcis Leja on the current status and future prospects of stomach cancer screening in Europe.
Although the Council of the European Union has recommended the introduction of stomach cancer screening, guidelines on how to implement this process still need to be developed. The "search and treat" strategy for *Helicobacter pylori* (H. pylori), which involves actively detecting the infection and eradicating it if the test is positive, is the most promising strategy for Europe. The article also provides an overview of current implementation studies in Europe: GISTAR, Eurohelican, TOGAS, EUCanScreen.
SUMMARY
The absolute number of stomach cancer cases in Europe is increasing every year. The Council of the European Union has recommended introducing stomach cancer screening in countries or regions with high incidence and mortality rates. However, as of 2024, no organized stomach cancer screening program has been launched in Europe.
There are several ways to reduce the burden of stomach cancer, but the *Helicobacter pylori* "search and treat" strategy seems the most suitable for Europe. It should be noted that this strategy would involve increased use of antibiotics.
In the European Union, only organized population-based cancer screening is recommended, so stomach cancer screening must meet the criteria of an organized screening program. Several aspects of screening organization must be considered before fully implementing stomach cancer prevention in Europe, including the target age group, types of tests, H. pylori eradication regimens, and monitoring strategies. Projects such as GISTAR, EUROHELICAN, TOGAS, and EUCanScreen are expected to provide the necessary evidence. Feedback from policymakers and potential target groups, including vulnerable populations, will be crucial for program planning.
This article provides an overview of recent decisions by European institutions, progress in the implementation of stomach cancer screening in Europe, and the challenges ahead. Finally, a potential algorithm for stomach cancer screening in Europe is proposed.
*Gut is a leading international journal in gastroenterology and hepatology, known for publishing high-quality clinical research on the digestive tract, liver, bile ducts, and pancreas. *Gut* offers up-to-date, authoritative, and clinically relevant content in all areas of gastroenterology and hepatology. Articles regularly describe new disease mechanisms and new diagnostic and treatment strategies that are likely to influence clinical practice in the near future, authored by leading experts in the field.

M. Leja Receives Recognition in South Africa for Support in Science
On August 16-17, 2024, the 1st International African Helicobacter and Microbiota Study Group (AHMSG) Inaugural Conference took place in Cape Town, South Africa. During the event, recognition was awarded to four scientists for their support, one of whom was Mārcis Leja, Director of the Institute of Clinical and Preventive Medicine at the University of Latvia.
This group was established two years ago in Nigeria, following the good experience of Europe, specifically modeled after the European Helicobacter and Microbiota Study Group. Two representatives from the European group, including one from Latvia, Professor Mārcis Leja, participated in its founding. Following the group's establishment, work began on developing the first African guidelines, with European representatives also participating in this effort.
The document was published earlier this year in the journal Digestive Diseases. This year, the conference saw broader representation from countries outside Africa, including scientists from Japan and the United States. The authors of the group's initiatives awarded their recognition to four guests for their support of the African countries' initiative, one of whom was M. Leja. The experience, including that of Latvia, which experts are ready to share with specialists on the African continent, was discussed. In his report, M. Leja provided an overview of the progress of the GISTAR, Eurohelican, TOGAS, and EUCanSCreen projects.

One of the stages of the GISTAR study led by the Institute of Clinical and Preventive Medicine of the University of Latvia was successfully implemented in Saldus, 548 participants were surveyed
The research center in Saldu was opened for the first time in 2015, nine years later the research center was opened for the second time, where 548 GISTAR participants came to the survey by the end of July 2024.
Various types of information were collected from the study participants about the events of the digestive system, heart and metabolic diseases since the first visit, lifestyle and eating habits and many other questions.
The GISTAR study is unique not only in Latvia, but also in Europe, and it has gained international attention. Some of the participants in the GISTAR study had received a course of treatment to eradicate H. pylori - now a special breath test was performed at the research centers to determine whether the eradication was successful. Blood tests were taken for all participants, in which various parameters related to inflammation and metabolism will be determined in the near future. These analyzes will also be performed on samples taken from participants nine years ago and stored frozen in the laboratory. The results of the old and new analyzes will be compared. Whether there is any relationship between changes in assays and health-related events with the use of H. pylori eradication medication will be investigated. It will also be evaluated whether there are any connections with the fact that the H. pylori infection is not treated.
All participants were offered a fecal immunochemical test to detect the presence of occult blood in the stool, and those who tested positive were advised to undergo a colonoscopy, or colon examination. During this examination, polyps or formations can be detected, the removal of which reduces the risk of developing colon cancer.
Researcher of the Institute of Clinical and Preventive Medicine of the University of Latvia, gastroenterologist Dr. med Danute Ražuka-Ebela says: "From the spring of 2023, the research centers in Ludza, Alūksne, Cēsis and Saldu have started and finished their operations, where GISTAR participants included in the study from 2014 and 2015 have been invited to the survey. Currently, the center in Rēzekne continues to operate. In total, more than 2,000 people came to the survey in the research centers (Ludzā 546, Alūksne 331, Cēsīs 332, Saldū 548, Rēzekne 340). Extensive work with the data and its analysis is currently underway. We are very grateful to the research participants for the time invested in the name of a common goal."
About GISTAR: A multicenter randomized trial to reduce gastric cancer mortality by H. pylori eradication and pepsinogen measurement. The study has been ongoing in Latvia since 2013.
The project "Accelerating the reduction of stomach cancer in Europe by eradicating H. pylori" (abbreviated as EUROHELICAN) is a project supported by the EU program "EU for Health" (EU4Health). As part of this, a population-based strategy for H. pylori testing and eradication is being evaluated. Infection with H. pylori significantly increases the risk of developing stomach cancer: most cases of stomach cancer are related to this infection. The project evaluates the use of the H. pylori testing and eradication strategy at the population level and various aspects of the strategy. The use of this strategy among young people is being studied in Slovenia. In Latvia, the long-term effects of this strategy are evaluated by surveying the participants of the GISTAR study.
In Latvia, the EUROHELICAN project is led by the Institute of Clinical and Preventive Medicine of the University of Latvia in cooperation with the National Institute of Public Health of Slovenia (The National Institute of Public Health - NIJZ), the International Agency for Research on Cancer of the World Health Organization (IARC) /WHO France), Nantes University Hospital (Nantes University Hospital, France) and Maribor Dr. Community Healthcare Center Dr. Adolf Drolc Maribor, Slovenia. The project will continue until the end of April 2025.

The study will last until 01.04.2026. for the year. It is planned to include 300-400 participants aged 30-34.
"The goal of the TOGAS project is to develop recommendations for the introduction of gastric cancer screening in EU countries. In order to achieve this, three large-scale pilot studies are being conducted, with the help of which various aspects of gastric cancer screening and early diagnosis are being developed within 36 months," said Linda Mežmale, researcher at LU KPMI.
This type of research is needed because there is currently a lack of effective gastric cancer screening methods in Europe. Current research shows that the eradication of Helicobacter pylori, a bacteria that lives in the stomach and promotes the development of stomach cancer, could reduce the number of deaths caused by stomach cancer by as much as 40%, so it is important to find ways to implement this prevention in practice.
The pilot study - "Detection and treatment of Helicobacter pylori infection in the young population" is part of the international project "Towards Gastric Cancer Screening Implementation in the European Union, TOGAS", which aims to develop recommendations for gastric cancer screening for implementation in European Union (EU) countries. This pilot study will be implemented not only in Latvia, but also in other EU countries (Slovenia, Ireland, Croatia, Poland, Romania).
The aim of the study is to evaluate a population-based H. pylori test-and-treat strategy in a young population for gastric cancer prevention.
During the research, it is planned to detect H. pylori and eradicate the bacterium in a group of young people aged 30-34 years. Based on the obtained results, the participation level of the invited individuals in the study will be analyzed, the H. pylori eradication therapy and its side effects will be evaluated. The results of this study will provide essential information needed for the development and implementation of a gastric cancer screening program strategy in the European Union. Experts from the World Health Organization's International Agency for Research on Cancer will develop recommendations for the implementation of gastric cancer prevention measures and their effectiveness evaluation at the European level. The established guidelines and recommendations will help European countries to include these gastric cancer prevention measures in their health care priorities.
The project "Towards Gastric Cancer Screening Implementation in the European Union" (TOGAS) has received funding from the EU4Health program of the European Union in accordance with grant agreement no. 101101252.

Healthy individuals between the ages of 40 and 64 were invited to voluntarily participate in the scientific project, which was launched in 2013. Participants were randomly assigned to control and intervention groups. Participants filled out a questionnaire that collects baseline indicators, lifestyle habits, as well as medical history. The presence of H. pylori infection and pepsinogens in blood tests were determined in the participants of the intervention group. Participants with H. pylori infection were offered eradication of the bacterium. Those with decreased pepsinogen levels (indicating possible changes in the stomach lining associated with an increased risk of developing cancer) were offered an upper endoscopy, or gastroscopy. All study participants were offered a fecal occult blood test for colorectal cancer screening and, in case of a positive test, these individuals were invited for a colonoscopy. More than 10 years have passed since the first participant was included, and the survey of participants is currently underway.
Colorectal (colon and rectal) cancer and stomach cancer are the most common tumors of the digestive system. Many of the cancers can be prevented by early detection of changes or precancerous conditions associated with a higher risk of developing cancer. Likewise, if the malignant process is detected early, it is still possible to successfully cure it.
Digestive system tumors account for a large proportion of the total number of tumors worldwide, with 3.88 million new cases diagnosed each year and 2.83 million deaths from digestive system tumors each year.
