Breast Cancer: Affordable Tests Could Result in Relapse Risk Z

Published

on

Researchers are working on an affordable test that determines the response of a breast cancer patient to hormone therapy to quickly predict the likelihood of a relapse.

Scientists estimate the cost of the test at about 60 pounds per patient, compared to currently available genomic tests which cost over 20 times that.

It finds deviations in cancer cell growth rate after treatment with aromatase inhibitors which inhibit estrogen production.

Researchers observe that using tests could reassure women who could do well under standard treatment and identify the ones are more likely to relapse.

”This important trial is the largest of its kind in the world and involved around 4,500 patients in 130 NHS breast units throughout the UK,’’ said the trial chief investigator, Professor Ian Smith, an honorary cancer medicine professor at the Cancer Research Institute in London.

‘’We have shown that giving patients with early breast cancer two weeks of simple endocrine therapy using aromatase inhibitor tablets before surgery allows us to determine what is the most appropriate medical treatment after surgery for each patient.

”In particular, it helps us identify which patients could avoid chemotherapy with all its unpleasant toxicities. The test is much cheaper and easier than current genomic tests, and we believe it should become part of the standard treatment for early breast cancer.”

A study of women with hormone-positive early-stage breast cancer by researchers team from Cancer Research Institute, London, and the Royal Marsden NHS Foundation Trust, in a situation where cancer cells grow, responding to progesterone or estrogen hormone, or both.

Of 4,480 patients, two-thirds received aromatase inhibitors, either anastrozole or letrozole, two weeks prior to and after surgery. The rest were treated with surgery, receiving aromatase inhibitors at the usual time, after surgery only.

All patients were instructed to proceed with hormone treatment up to at least 5 years as part of standard care to reduce the coming back risk of breast cancer.

The researchers used a cancer growth rate test. It looks for Ki67 protein in tumor samples to check for any effect of the pre-surgery hormone treatment. The team could find out from the test the patients who were at higher or lower risk to see a return of the disease.

‘’Sadly, breast cancer can return for some women, so a new way to help predict if their cancer will return means doctors could monitor these patients more closely – catching any sign of cancer as early as possible is crucial for improving survival,’’ said Professor Arnie Purushotham. A senior clinical advisor UK Cancer Research.

‘’This research could also have implications for how doctors decide to treat early-stage, hormone-positive breast cancer – potentially triaging women depending on the risk of their cancer coming back.’’

In a groundbreaking development, researchers have unveiled a new artificial intelligence model that promises to revolutionize the field of protein structure prediction. This cutting-edge AI system has demonstrated unprecedented accuracy in determining the three-dimensional shapes of proteins, a feat that could accelerate drug discovery and deepen our understanding of fundamental biological processes.

The new model, developed by a team of international scientists, builds upon the success of previous AI-driven approaches like AlphaFold and RoseTTAFold. These earlier systems had already made significant strides in tackling the protein folding problem, a challenge that has puzzled scientists for over half a century. However, the latest innovation takes protein structure prediction to new heights, offering a level of precision that was previously unattainable.

Proteins, the building blocks of life, perform a vast array of functions in living organisms. Their functionality is intimately tied to their three-dimensional structure, which has traditionally been determined through complex and time-consuming experimental methods such as X-ray crystallography and cryo-electron microscopy. The ability to accurately predict these structures from amino acid sequences alone has long been a holy grail in structural biology.

The new AI model employs advanced machine learning techniques, including deep neural networks and attention mechanisms, to analyze vast amounts of genomic and proteomic data. By leveraging evolutionary information and physical principles, the system can infer the most likely structural configuration of a given protein sequence.

Dr. Sarah Chen, lead researcher on the project, explained, “Our model doesn’t just predict the overall fold of a protein; it can pinpoint the positions of individual atoms with remarkable accuracy. This level of detail is crucial for understanding protein function and for designing drugs that can interact with specific molecular targets.”

The implications of this breakthrough are far-reaching. In the field of drug discovery, accurate protein structure predictions can significantly accelerate the process of identifying potential therapeutic compounds. By simulating how different molecules interact with target proteins, researchers can narrow down candidates for experimental testing, potentially saving years of laboratory work and billions of dollars in development costs.

Moreover, the new model’s capabilities extend beyond single proteins to complex molecular assemblies.

In a landmark move to address global health disparities, the World Health Organization (WHO) has announced the launch of the Health Technology Access Pool (HTAP). This initiative, set to officially commence in the second quarter of 2024, aims to revolutionize access to essential health technologies worldwide, building upon the lessons learned from its predecessor, the COVID-19 Technology Access Pool (C-TAP).

The HTAP represents a significant evolution in WHO’s approach to health technology access, expanding its scope beyond pandemic response to encompass a broader range of public health priorities. Dr. Tedros Adhanom Ghebreyesus, WHO Director-General, emphasized the initiative’s importance, stating, “Equitable access to essential health products is an essential part of universal health coverage, and of global health security.”

At its core, HTAP seeks to facilitate the sharing of intellectual property, knowledge, and data among technology developers, manufacturers, and health organizations. This collaborative approach aims to accelerate innovation and expand global production capacity for critical health technologies. The initiative’s expanded focus includes not only pandemic preparedness but also addresses other pressing public health concerns, targeting platform technologies and health products relevant both during and between health emergencies.

One of the key strengths of HTAP lies in its comprehensive engagement across the entire technology value chain. This holistic approach considers the various steps and support required to transform licensed technologies into sub-licensed, quality-assured products with viable market potential. By doing so, HTAP aims to enhance the attractiveness of licensed technologies to recipient manufacturers, offering greater market opportunities and financial sustainability in non-pandemic periods.

The initiative’s strategy is built around fostering partnerships across the value chain, from research institutions to manufacturers and end-users. This collaborative model is designed to ensure the successful implementation of HTAP and address access gaps on an ongoing basis. WHO plans to provide further details on HTAP’s operations and targeted technologies in the first quarter of 2024, with the official launch tentatively scheduled for the second quarter.

HTAP’s approach represents a significant departure from its predecessor, C-TAP, which was launched in May 2020 in collaboration with the Government of Costa Rica and other partners. While C-TAP focused primarily on facilitating access to COVID-19 health products, HTAP expands its purview to future emergencies and other priority diseases. This expansion is coupled with a more proactive approach, full integration within the access ecosystem, and alignment with existing WHO programs.

The initiative also adopts a nuanced approach to licensing, recognizing the need for differentiated strategies when dealing with mature health products versus upstream technologies. This flexibility allows HTAP to work with technology holders and partners on tailored technology transfer implementation strategies, taking into account market dynamics and potential saturation.

HTAP’s potential impact on global health equity is significant, particularly for regions like Africa that have historically faced challenges in accessing cutting-edge health technologies. Dr. Ahmed Ogwell, Africa CDC’s deputy director, hailed the platform as “urgently needed” to bridge the existing technology development gap. He emphasized the potential for HTAP to be a game-changer for the African continent and other parts of the world where technological development lags behind the West.

The initiative’s voluntary nature allows countries to leverage useful technologies as soon as they become available. However, Dr. Ogwell also acknowledged the uncertainty surrounding whether those possessing highly sought-after technologies would willingly share their products on the platform. Despite this challenge, he remains optimistic that HTAP, based on agreed parameters, will encourage voluntary contributions of intellectual property rights and knowledge to the platform.

To ensure its success, HTAP will harness and align WHO resources, leveraging the necessary expertise and programs in setting priorities, developing enabling policies, and providing support over the value chain. This approach extends to partnerships with external entities that form part of the larger health product access ecosystem.

The WHO is also focusing on building the infrastructure and governance structure necessary for HTAP’s success. This includes staffing senior dedicated positions to manage and monitor HTAP’s performance, establishing a WHO-led steering group with defined purposes, and implementing an evaluation framework to measure success. The development and publication of clear operating procedures, guidance, and advocacy materials will be critical to HTAP’s launch and ongoing operations.

As the world continues to grapple with health inequities exposed and exacerbated by the COVID-19 pandemic, initiatives like HTAP offer a beacon of hope. By promoting continuity and alignment along the value chain, HTAP seeks to achieve sustainable success in improving global health outcomes. The initiative’s focus on equitable access to health technologies could play a crucial role in advancing universal health coverage and strengthening global health security.

However, the success of HTAP will largely depend on the willingness of technology holders to participate and the ability of recipient countries to absorb and utilize the shared technologies effectively. As Dr. Ogwell pointed out, African countries and other developing nations must ramp up investments in their health sectors to fully benefit from this initiative.

As we approach the official launch of HTAP, the global health community watches with anticipation. If successful, this initiative could mark a significant step forward in addressing health disparities and ensuring that life-saving technologies reach those who need them most, regardless of geographical or economic barriers.

The Health Technology Access Pool represents a bold vision for a more equitable global health landscape. By learning from past experiences and adopting a more comprehensive, proactive approach, WHO aims to create a sustainable model for technology sharing that could revolutionize how we address global health challenges. As the world continues to face both known and unforeseen health threats, initiatives like HTAP may prove crucial in building a more resilient and equitable global health system for all.
