The Petersen prognostic index revisited in Dukes B colon cancer – Inter-institutional differences

The Prognostic Yield of Biomarkers Harvested in Chemotherapy-Naive stage II Colon Cancer: Can We Separate the Wheat from the Chaff?

“…Much energy has been put into gene panels that would yield better prognostic and predictive tools for risk assessment (21)(22)(23), but the results are thus far disappointing, with no panels having reached widespread incorporation in clinical practice. The same goes for most other proposed prognostic systems (9,19,(24)(25)(26).…”

Vascular invasion detected by orcein staining and its significance in different tumours, with emphasis on colorectal cancer

“…In a collaborative study of our group, the performance of the Petersen index was compared in two centres. Although VI detection rate was significantly higher in one centre, and tumour perforation was more commonly detected in the other, the results confirmed the usefulness of this prognostic index [50]. This also suggests that a single adverse parameter (unless it is transtumoural perforation considered with more weight) has less effect on overall prognosis, and with that the tumour is still placed in the good prognostic category.…”
