36+ min ago (164+ words) Expert explores innovative strategies for managing early stage breast cancer, focusing on minimal residual disease and potential treatment adjustments. The primary recommendation for these patients is enrollment in clinical trials designed to test the efficacy of intensified or switched systemic therapies, with the goal of achieving MRD clearance and preventing overt recurrence. Unfortunately, there are no currently available data or guidelines to support the safe de-escalation or cessation of treatment based on ctDNA clearance or sustained negativity in the early-stage setting. The concept is highly promising but remains hypothetical and requires validation through prospective trials. In summary, ctDNA remains a powerful prognostic marker driving research, but its use as a directive for escalation or de-escalation of treatment is currently confined to the context of clinical trials. In an interview with Targeted Oncology, Stefania Morganti, MD, PhD, research fellow at the…...

36+ min ago (230+ words) Targeted Oncology connects oncology professionals with updates on immunotherapy, biomarkers, cancer pathways, and targeted precision medicine strategies. The field of circulating tumor DNA (ctDNA) for minimal residual disease (MRD) testing is experiencing rapid technological advancement, with new assays demonstrating increasing sensitivity by orders of magnitude compared to previous generations. This progress has generated significant excitement regarding its potential to revolutionize breast cancer management. The central challenge, however, remains the lack of proven clinical utility. While ctDNA is highly promising, particularly across the neoadjuvant, adjuvant, and even metastatic settings, its current function is primarily prognostic. Standard clinical practice currently relies on a probabilistic approach, estimating a patient's general risk of recurrence but it fails to provide the precise, individual-level risk stratification needed for personalized therapy selection. MRD testing offers the potential to move beyond probabilistic risk to a single-patient-level assessment of…...

1+ day, 7+ min ago (234+ words) Early-stage breast cancer patients face challenges with ctDNA detection, highlighting the need for clinical trials to improve outcomes and reduce recurrence risks. In an interview with Targeted Oncology, Stefania Morganti, MD, PhD, research fellow at the Dana-Farber Cancer Institute, addressed the current clinical utility and inherent limitations of using circulating tumor DNA (ctDNA) for minimal residual disease (MRD) detection in early-stage breast cancer. A primary concern is the high risk of false-negative results due to the potentially very low amounts of ctDNA present in this patient population. Clinicians must stress this limitation to patients, according to Morganti, highlighting that a negative result may not equate to the absence of disease. Furthermore, the limit of detection varies significantly across different ctDNA assays. Tests with a lower limit of detection offer a decreased chance of a false negative, while those with a…...

1+ day, 4+ hour ago (314+ words) Emerging research highlights the challenges and potential of ctDNA in managing minimal residual disease in breast cancer, paving the way for innovative treatment strategies. The presence of minimal residual disease (MRD), specifically circulating tumor DNA (ctDNA) positivity, in patients achieving complete remission (CR) poses a significant clinical challenge. Currently, standard follow-up imaging (CT/PET) is not approved for early-stage breast cancer, creating a diagnostic dilemma for MRD-positive but image-negative patients.1 For these MRD-positive patients without detectable metastatic disease on imaging, the current recommendation is enrollment in clinical trials exploring the addition of novel therapeutic agents, aiming for MRD eradication. The use of MRD to guide treatment de-escalation is promising but lacks current data for widespread clinical recommendation. Trials are being considered to explore de-escalation, or treatment breaks in both the early-stage and metastatic settings, such as using sustained ctDNA clearance…...

1+ day, 4+ hour ago (171+ words) Targeted Oncology connects oncology professionals with updates on immunotherapy, biomarkers, cancer pathways, and targeted precision medicine strategies. This concluding segment brings together expert reflections on the practical use of combination immunotherapies in newly diagnosed advanced melanoma. Panelists share their clinical impressions regarding efficacy, safety, and patient-reported outcomes, underscoring the importance of individualized care. They discuss encouraging results with dual checkpoint blockade and how emerging regimens have expanded the therapeutic window for more patients. A key focus is the role of patient characteristics'such as tumor burden, comorbidities, and immune-related risk factors'in guiding regimen selection. Panelists emphasize that effective treatment requires a nuanced understanding of the interplay between disease biology and immune modulation. Looking ahead, they identify biomarker development and neoadjuvant therapy as areas of growing importance. Advances in predictive testing, molecular profiling, and perioperative immunotherapy are expected to enhance precision and…...

4+ day, 13+ hour ago (399+ words) Lifileucel shows sustained efficacy and safety in advanced melanoma, highlighting its potential as a key treatment for ICI-resistant cases. Five-year follow-up data from the phase 2 C-144-01 study (NCT02360579) show that lifileucel (Amtagvi) maintained efficacy and favorable safety in pretreated patients with advanced melanoma,1 showcasing the long-term promise of the 1-time autologous tumor-infiltrating lymphocyte (TIL) cell therapy. In terms of survival, the median overall survival (OS) for the overall population was 13.9 months (95% CI, 10.617.8), and the 5-month OS rate was 19.7%. These final analysis data were also presented earlier this year at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting. Overall, the data solidify lifileucel as a durable, clinically meaningful treatment option and reinforce its critical role in immune checkpoint inhibitor (ICI)-resistant advanced melanoma. "This 5-year analysis is the longest follow-up of lifileucel in patients with ICI-resistant melanoma," wrote study authors Medina et al…...
