Intratumoral stromal morphometry predicts disease recurrence but not response to 5‐fluorouracil—results from the QUASAR trial of colorectal cancer

The biological importance of tumour‐associated stroma is becoming increasingly apparent, but its clinical utility remains ill‐defined. For stage II/Dukes B colorectal cancer (CRC), clinical biomarkers are urgently required to direct therapeutic options. We report here prognostic/predictive analyses, and molecular associations, of stromal morphometric quantification in the Quick and Simple and Reliable (QUASAR) trial of CRC.
