Advancements within Oncology Diagnostics

When it comes to fighting cancer, early and accurate diagnosis is everything. The faster and more precisely we can identify cancer, the better a patient’s chance of successful treatment. In recent years, oncology diagnostics has seen remarkable advancements, bringing more powerful tools into the hands of healthcare providers and making it possible to catch cancer earlier and personalise treatment options in ways that seemed impossible a decade ago.

So, how are these advancements transforming oncology? This guide will explore advancements from improved imaging to molecular testing, recent breakthroughs and the future of diagnostics, and the importance of oncology jobs and professionals within the sector. 

What are the Key Advancements in Oncology Diagnostics?

When we talk about advancements in oncology diagnostics, it’s helpful to understand the types of diagnostic tests that are making a difference. Each plays a different role in detecting and diagnosing cancer, and recent improvements have only made them more effective:

1. Imaging Tests

Imaging has been around for decades, but recent advances in technology are making these tools even more powerful. X-rays, MRIs, CT scans, and PET scans are still the go-to methods for visualising tumours, but today’s machines can capture images with much higher resolution and in less time. With modern imaging, doctors can spot smaller tumours at an earlier stage, making it easier to treat them before they grow or spread.

Some of the latest innovations even include AI-powered image analysis, which can detect subtle signs of cancer that the human eye might miss. With the growing use of AI in cancer diagnostics, imaging is becoming faster and more precise, helping healthcare teams make better decisions right from the start.

2. Molecular Testing

Molecular diagnostics are at the heart of personalised medicine in oncology. These tests look at a cancer cell's DNA, RNA, or proteins to identify specific mutations or biomarkers. Given the complexity of cancer, this information is invaluable—it tells doctors not just what type of cancer a patient has but also provides clues about how that cancer might behave and respond to specific treatments.

Companion diagnostics in oncology are a great example of how molecular testing can be used to personalise treatment. These tests identify specific genetic markers in a tumour that can indicate whether a particular drug will be effective. In other words, instead of a one-size-fits-all treatment, molecular testing helps doctors find the right therapy for each patient’s unique cancer profile. The result? Fewer side effects, higher success rates, and often, better survival outcomes.

3. Liquid Biopsies

Liquid biopsies are one of the newer tools in the oncology diagnostics toolkit, and they’re changing the way we think about monitoring cancer. Traditional biopsies require a tissue sample from the tumour, which can be invasive and sometimes challenging to obtain. Liquid biopsies, on the other hand, use a blood sample to detect fragments of cancer DNA floating in the bloodstream.

The real advantage here is that liquid biopsies are far less invasive and can be done repeatedly to monitor a patient’s response to treatment or check for recurrence after treatment. While still relatively new, liquid biopsies hold great potential for helping doctors stay a step ahead of cancer progression. 

Fundamental Diagnostics Advancements in Early Cancer Detection

Advancements in cancer diagnostics are revolutionising early detection, making it possible to catch cancers at their most treatable stages. With innovations in oncology and early detection, scientists can now identify and treat cancer more accurately than ever before.

With this in mind, let’s explore some of the critical diagnostic advancements in early cancer detection:

Screening Techniques

Screening has come a long way, with tools like mammograms, colonoscopies, and low-dose CT scans now considered standard for early cancer detection. But the latest screening advancements go even further. Today, AI algorithms are increasingly being used to analyse imaging results, which enhances the ability to spot abnormalities that could indicate cancer.

For example, some hospitals are now using AI-driven mammograms to detect early-stage breast cancer with fewer false positives. It’s incredible to think that AI is now part of the diagnostic process, but these tools are helping healthcare providers catch cancer at its earliest, most treatable stages.

Biomarkers

Biomarkers are biological indicators that can point to the presence of cancer even before a person shows symptoms. Some cancers, like prostate cancer, produce specific proteins (like PSA) that can be detected in blood tests. The discovery of new biomarkers has opened up new ways to identify cancer early and determine its type and characteristics.

For patients, this means there’s now a more substantial chance of detecting cancer before it becomes advanced.

Breakthroughs and the Future of Cancer Diagnostics

As we know, rapid identification improves treatment outcomes, yet pinpointing the primary site remains challenging in cases of cancer of unknown primary (CUP), where 3–5% of cancers have no detectable origin. 

For up to 50% of CUP patients, the origin remains undetectable due to tiny lesion size—often under 1 cm. While diagnostic advances have improved early detection and personalised treatments, CUP cases highlight the need for further research in early detection, precise diagnostics, and targeted therapies.

Here are the up-and-coming diagnostic advancements in oncology that are beginning to improve patient outcomes:

PET/CT Imaging

PET/CT imaging, especially with 18F-FDG tracers, has become essential in diagnosing and staging cancer. This imaging technique has proven effective in identifying primary tumours, significantly reducing cases of cancer of unknown primary (CUP) in head and neck cancers from 2-9% to 1-2%. However, PET/CT does come with limitations, including radiation exposure and high costs.

Novel PET Tracers

A new PET tracer, [68Ga]Ga-FAPI-4, targets fibroblast activation protein (FAP) and offers improved specificity in cancer imaging over traditional 18F-FDG tracers. This advancement marks a promising step in enhancing diagnostic accuracy and detail for more precise cancer detection.

Artificial Intelligence and Machine Learning

AI in cancer diagnostics is transforming healthcare in a variety of ways:

• Predictive Models: Researchers at MIT developed an AI model, "Sybil," that can predict lung cancer risk up to six years in advance from low-dose CT scans.
• Image Analysis: AI algorithms now analyse medical imaging data, boosting the accuracy and speed of cancer detection and characterisation.
• Digital Twins: AI enables the creation of patient-specific virtual models, allowing healthcare providers to simulate and assess treatment options before real-world application.

Cryo-Electron Microscopy (Cryo-EM)

Cryo-EM technology offers high-resolution images of molecules at the cellular level, providing a detailed view of cancer cell behaviour and drug interactions that was previously unattainable.

CRISPR Gene Editing

Though primarily used in research, CRISPR gene editing shows potential in developing new cancer diagnostics and targeted therapies by allowing precise manipulation of genes associated with cancer development.

Multi-Cancer Early Detection Tests

Blood-based tests capable of detecting multiple cancers at early stages are emerging. For example, a test by Novelna identified stage 1 cancers in 93% of men and 84% of women across 18 cancer types, representing a significant advancement in early cancer detection.

Genomic Analysis

Advances in genomic sequencing are deepening our understanding of cancer:

• Precision Oncology: Detailed genetic and molecular profiling of tumours allows for personalised treatment strategies tailored to each patient’s unique cancer type.
• Mutational Signatures: Analysing cancer DNA reveals specific mutational patterns that provide insights into cancer’s causes and progression.

Low-Cost Diagnostic Tools

Efforts to create affordable cancer diagnostics, especially for use in low- and middle-income countries, have led to innovations like CryoPop®, LumaGEM®, and MarginProbe®. These tools aim to increase access to early and accurate cancer diagnostics globally.

These advancements collectively enhance cancer diagnostics by improving accuracy, accessibility, and early detection, setting the stage for more effective, personalised cancer care.

Personalised Cancer Vaccine

Thousands of NHS cancer patients in England may soon participate in trials for a new personalised cancer vaccine. This vaccine primes the immune system to target cancer cells, aiming to reduce recurrence risk with fewer side effects than chemotherapy. Over 200 patients in the UK, Germany, Belgium, Spain, and Sweden are set to receive up to 15 doses, with the study expected to conclude by 2027.

Seven-minute Cancer Treatment Jab 

England’s NHS is set to be the first in the world to offer a cancer treatment injection that takes just seven minutes instead of the hour-long intravenous infusion currently used. A faster treatment means less time for patients and more efficiency for healthcare professionals. The drug, Atezolizumab (Tecentriq), treats cancers like lung and breast cancer, and it is anticipated that most of the 3,600 NHS patients currently getting it via infusion will soon switch to the injection.

Breast Cancer Tablet to Reduce Risk

Almost 300,000 women in England at high or moderate risk of breast cancer are now able to take a drug that can cut their risk by half. Anastrozole, a tablet taken daily for five years, is being made available to women who are post-menopausal and have a strong family history of breast cancer. This breakthrough offers a major step forward in prevention, potentially reducing the number of new cases of the disease. The NHS hopes this will help thousands of women avoid the emotional and physical toll of a breast cancer diagnosis.
