Benefit of adjuvant chemotherapy in patients with ctDNA-positive resected stage II colon cancer

 The CIRCULATE study, comprised of investigators from Arbeitsgemeinschaft Internistische Onkologie (AIO) and the Austrian Breast and Colorectal Cancer Study Group (ABCSG) "evaluated a treatment escalation strategy [to determine] whether patients with circulating tumour DNA (ctDNA)-positive status would benefit from capecitabine-based adjuvant chemotherapy after resection for stage II colon cancer".  While the study could not be fully completed due to lapse of funding, preliminary results indicated that time to recurrence and disease-free survival were improved with chemotherapy vs. observation: 3-year recurrence was 19% vs. 62%, while 3-year disease-free survival was 77% compared to 38%.

Aiming to improve cancer prevention, ESMO calls for strong policy measures to fight the tobacco epidemic

 The European Society for Medical Oncology (ESMO) recently submitted its response to the European Union in regards to the Tobacco Products and Tobacco Advertising directives.  As per ESMO, "up to 40% of all cancers are preventable...robust tobacco cessation policies are among the most effective strategies for reducing the risk of cancer, improving human health, and reducing cancer cases."  According to the International Agency for Research on Cancer (IARC), 7 000 000 million people worldwide die from tobacco use each year (700,000 deaths in Europe alone), contributing to 25% of all cancer-related deaths.

Blood test may help identify which colorectal cancer patients with liver metastases are most likely to benefit from chemotherapy after surgery

Research recently present at the European Society for Medical Oncology (ESMO) Gastrointestinal Cancers Congress in Munich, Germany, indicates that a blood test may identify colorectal cancer patients which has metastasized to the liver and thus "most likely to benefit from chemotherapy after surgery."   Known as GALAXY, the joint phase II study between researchers and collaborations from Hyogo Medical University in Japan and the University of Oxford determined that "among patients with detectable ctDNA who underwent upfront surgery, those who received adjuvant chemotherapy had substantially better outcomes...[with] a markedly lower risk of cancer recurrence and death, including a 93% reduction in the risk of recurrence."

A single colonoscopy reduces colorectal cancer risk, but not mortality

 Findings from the NordiCC (Nordic Colorectal Cancer) group, a 13-year follow-up study that "enrolled men and women aged 55-64 years, who were randomly allocated to colonoscopy screening or no screening" was recently published in The Lancet.  Study authors commented that they did not observe a clinically relevant cancer stage shift between the screening and non-screened groups of participants.  Further, "stage shift of cancer due to screening applies only to cancers detected at screening or surveillance after screening."  At 13 year follow-up, screening-detected colorectal cancer only occurred in 16% in the screening group; "cancers detected later were due to clinical symptoms, as there was no colonoscopy screening."

Towards a chemotherapy-free future in breast cancer?

 New research, set to be discussed at the European Society for Medical Oncology [ESMO] Breast Cancer Congress (May 6-8, 2026 in Berlin) purports that "a less intensive chemotherapy regimen is associated with improved quality of life for patients, without compromising clinical outcome."  Traditional approaches to treatment, with an intent to extend treatment for several years to maximize tumour control, may lead to "unnecessary toxicities and treatment burden."  Multimodal strategies are being explored to de-escalate treatments, such as removing carboplatin from chemotherapy in a neoadjuvant setting, or a positron emission tomography (PET)-guided strategy "associated with a high 3-year invasive disease-free survival rate in patients with HER-2 positive early breast cancer who omitted chemotherapy."

Rare cancer patients still have limited access to personalized care in Europe

 Findings from a recent study presented at the ESMO Sarcoma and Rare Cancer Congress indicate a substantial gap between precision oncology and real-world access to high-quality cancer treatments, with "only one in five patients with advanced rare cancers able to access treatment matched through individual molecular profiling."   In addition, the study found very limited patient enrollment in clinical trials for rare cancer care; out of 304 patients recommended for clinical trials, only 6 were enrolled."

Redesigning oncology clinical trials with agentic AI

 

Over the past few years, artificial intelligence (AI) has placed an increasing role in cancer research. AI tools "can be used to help improve the next generation of treatment options for patients in key tumour areas, leveraging real-life data...to combine new and existing therapies."   At the recent European Society of Medical Oncology (ESMO) Targeted Anticancer Therapies Congress, the following notion was brought forth: "AI is not the future - it is the present.  By learning how to best harness its power, we can help increased the speed and efficiency of personalized care delivery."

New survey highlights the role of clinical practice guidelines to improve care for patients with rare cancers

 Results from a recent ESMO (European Society for Medical Oncology) and EURACAN (European Reference Network to Cancers) had led to a "call for policy action to standardize care pathways for rare cancers after analysis links guidance adherence to patient survival").  According to the survey, conducted between September - October 2025, patients with rare malignancies equate to 650,000 new cases per year, representing 24% if all cancer diagnoses across Europe.  

ESMO and EURACAN thus propose the following actions: 

• Centralize rare cancer surgeries in accredited centres  
• Enforce mandatory multidisciplinary decision-making and time-critical standards throughout patient diagnosis, treatment, and follow-up
• Track adherence to established Clinical Practice Guidelines via national dashboards

Overall survival not substantially improved with CDK4/6 inhibitors used in first- compared with second-line treatment in Patients with HR-positive, HER2-negative advanced breast cancer

 Findings from SONIA, a phase III Dutch study comparing "the sequence of an aromatase inhibitor plus CDK4/6 inhibitor as first-line treatment followed by fulvestrant as second-line treatment (CDK4/6 inhibitor first-line group") did not improve overall survival compared with second-line treatment. Rather, this treatment regimen increased treatment-related and financial toxic effects in patients with HR-positive HER-2 negative advanced breast cancer.  Following an analysis of 1050 patients enrolled in SONIA, median overall survival was 47.9 months with first-line CDK4/6 inhibitor and 48.1 months with second-line CDK4/6 inhibitor

Worse survival among patients diagnosed with cancer during first 2 years of the COVID-19 pandemic

A recently published U.S. population-based cohort study found "significant reductions in 1-year cause-specific survival rates among patients diagnosed with both early-stage and late-stage cancer in 2020 and 2021."   Compared to cancer patients diagnosed between 2015-2019, patients with a diagnosis of esophageal cancer (early-stage, 3.67%-3.89%), colorectal cancer (0.78%-1.08%) and prostate cancer (late-stage, 0.64%-0.77%)), were noted to have the largest site-specific survival reductions during the first 2 years of the COVID-19 pandemic.  The authors of this cohort study thus propose that "swift action should be taken to increase cancer screening, rebuild healthcare capacity, and improve patient communication."

RAS inhibition in pancreatic cancer

 The Experimental Oncology Group at the National Research Centre (CNIO) in Madrid has recently unveiled findings from genetically engineered mice afflicted with pancreatic ductal adenocarcinoma.  The mice "underwent rapid apoptotic cell death that resulted in complete tumour regressions and remained tumour-free for over 200 days post-treatment."  While results of these animal studies are promising towards determining therapeutic vulnerabilities of pancreatic cancer, Dr. Ben Westphalen, chair of the European Society of Medical Oncology (ESMO) Precision Oncology Task Force cautions that these results cannot yet be applied to patient care. More work is needed to determine side effects of the triple combination therapy in humans.

Biological mechanism enabling breast cancer to spread to the brain uncovered

Researchers from the Gray Faculty of Medical and Health Sciences in Tel Aviv, in partnership with researchers in 14 laboratories in Israel, USA, Italy, Germany, Poland, and Austria, have uncovered "a mechanism that allows breast cancer to send metastases to the brain - a highly lethal occurrence for which there is currently no effective treatment."   Following injection of cancer cells with or without functional gene P53, results indicated that "cells with disrupted P53 activity thrived much more." These findings are crucial towards developing new drugs and personalized monitoring for early detection and treatment of brain metastases.

Rethinking the limits of tissue-agnostic cancer therapy

A recent editorial published in the ESMO Daily Reporter raises questions about the impact of precision medicine in personalized cancer care, considering that "patients are still largely treated according to the primary organ where their cancer originates."  Tumour-agnostic agents, drugs approved if cancer cells cause gene or protein changes, no matter where in the body the cancer originated, calls for physicians and patients to engage in precision medicine, "a first step toward a common understanding...in which tissue-agnostic development should be preferred to conventional trials."
