The Royal Free London NHS Foundation Trust, London, UK; UCL Division of Surgery and Interventional Science, University College London, London, UK; Department of Urology, The Netherlands Cancer Institute, Antoni van Leeuwenhoek Hospital, Amsterdam, The Netherlands.

Article Synopsis
  • Immune-oncology strategies are improving treatment for renal cell carcinoma (RCC), especially with the introduction of immunotherapy in the perioperative setting.
  • Adjuvant therapy with pembrolizumab has shown benefits in disease-free survival post-surgery but there's limited support for neoadjuvant therapies outside trials; both strategies have their risks and challenges.
  • While adjuvant immunotherapy is now a standard treatment, understanding the optimal use of neoadjuvant approaches is still unclear and requires further research in biomarker development and clinical trials.

High-dose chemotherapy for patients with stage III breast cancer with homologous recombination deficiency: a discrete choice experiment among healthcare providers.

Acta Oncol

September 2024

Division of Psychosocial Research and Epidemiology, The Netherlands Cancer Institute, Amsterdam, The Netherlands; Department of Health Technology and Services Research, University of Twente, Enschede, The Netherlands.

Background And Purpose: High-dose chemotherapy with autologous stem cell rescue (HDCT) is currently under investigation as a potential therapy for patients with stage III HER2-negative breast cancer with homologous recombination deficiency (HRD). In addition to survival, the impact on short- and long-term side effects might influence the uptake of HDCT by healthcare professionals. As part of the SUBITO trial, we investigated healthcare professionals' treatment (outcome) preferences for patients with HRD stage III HER2-negative breast cancer and established how healthcare professionals make trade-offs between these treatment outcomes.

Eur Urol

November 2024

Surgical Oncology (Urology), Netherlands Cancer Institute - Antoni van Leeuwenhoek Hospital, Amsterdam, The Netherlands; European Association of Urology, Non-Muscle Invasive Bladder Cancer Guidelines Panel, Arnhem, The Netherlands; Urology, Caritas St. Josef Medical Center, University of Regensburg, Regensburg, Germany; Surgical Oncology (Urology), University Health Network, Princess Margaret Cancer Center, University of Toronto, Toronto, Canada. Electronic address:

Grade is an important determinant of progression in non-muscle-invasive bladder cancer. Although the World Health Organization (WHO) 2004/2016 grading system is recommended, other systems such as WHO1973 and WHO1999 are still widely used. Recently, a hybrid (three-tier) system was proposed, separating WHO2004/2016 high grade (HG) into HG/grade 2 (G2) and HG/G3 while maintaining low grade.

Tertiary lymphoid structure-related immune infiltrates in NSCLC tumor lesions correlate with low tumor-reactivity of TIL products.

Oncoimmunology

August 2024

Sanquin Blood Supply, Division Research Immunotherapy, and Landsteiner Laboratory and Department of Experimental Immunology, Amsterdam University Medical Center, Amsterdam, Netherlands.

Adoptive transfer of tumor infiltrating lymphocytes (TIL therapy) has proven highly effective for treating solid cancers, including non-small cell lung cancer (NSCLC). However, not all patients benefit from this therapy for yet unknown reasons. Defining markers that correlate with high tumor-reactivity of the autologous TIL products is thus key for achieving better tailored immunotherapies.

Article Synopsis
  • There has been an increase in agents for treating bacillus Calmette-Guérin-unresponsive (BCG-U) non-muscle-invasive bladder cancer (NMIBC), and there is a pressing need for patient and therapy selection guidelines due to a lack of randomized trials.
  • A global expert committee developed recommendations through literature reviews and a voting process, refining these guidelines during a live meeting in August 2023, achieving over 75% agreement on the final recommendations.
  • No single optimal treatment exists for BCG-U patients; personalized treatment based on individual preferences, tumor characteristics, and available agent data is essential, with specific options recommended for carcinoma in situ and papillary-only tumors, and clinical trial participation encouraged.
