The fight against cancer is evolving beyond the tumor itself. As we uncover the profound influence of systemic factors—from the immune and nervous systems to the gut microbiome, metabolism, and beyond—the boundaries of cancer research are expanding like never before. This upcoming Cell Symposium on Hallmarks of cancer will explore how these interconnected systems shape tumor progression, treatment response, and patient outcomes, uniting foundational discoveries with transformative clinical applications.

Join us in the vibrant coastal town of Sitges, Spain, as we bring together pioneering scientists, physician-researchers, and clinicians to share groundbreaking insights into the systemic forces driving cancer biology. Whether your expertise lies in immunology, neuroscience, microbiology, metabolism, or cutting-edge technologies, this meeting will provide a dynamic platform to exchange ideas, foster collaborations, and accelerate the translation of science into life-saving therapies.

For over a decade, the Cell Symposia: Hallmarks of cancer series has stood at the forefront of cancer research, bridging disciplines and continents to advance our collective mission. As we gather in 2026, we invite you to be part of this legacy—celebrating the convergence of basic and translational science, sparking new connections, and shaping the future of precision oncology.

Key themes Include:

• The immune system’s role in cancer progression and therapy
• Gut microbiome and its systemic impact on tumor behavior
• Nervous system interactions with the tumor microenvironment
• Metabolism, exercise, and their influence on treatment outcomes
• Emerging technologies to decode systemic factors in cancer

Embrace this opportunity to engage with global leaders, discover paradigm-shifting research, and contribute to a more holistic understanding of cancer. Together, we can redefine what’s possible in patient care.

We look forward to welcoming you to Sitges for inspiring science, lively discussions, and the breathtaking beauty of the Mediterranean. Let’s illuminate the next frontiers—together.
