DR-080 The tumor-stroma ratio (TSR) as predictor of response to checkpoint inhibitors in patients with gastrointestinal malignancies

“Venous thromboembolism (VTE), a venous blood clot, frequently occurs in cancer patients, and substantially affects morbidity, quality of life, and mortality. Yet, it is incompletely understood why cancer patients are at increased risk of this disease. The risk of VTE varies greatly across cancer types, strongly suggesting a role for cancer-specific oncogenic mutations which indirectly cause thrombosis.
We aim to investigate this possible association by using clinical data and genomic data from tumor biopsies acquired within the CPCT-02 study. Results could help understand the pathogenesis of cancer-associated venous thromboembolism, lead to new therapeutic targets, and identify high-risk patients for thromboprophylaxis.”
