Abstract

Based on more than 11 years of follow-up, autopsy-based analysis of recurrence in the Dutch D1-D2 Trial permits meaningful assessment of patterns of failure with respect to the Maruyama Index (MI). We previously reported that a low Maruyama Index was an independent predictor of both overall and disease-specific survival. Autopsy results are available for 441 deaths on study. Distant-only failure (15% vs 13%) was no different between the MI categories, but isolated “regional” failure (8% for MI < 5 group vs 21%) and “regional + distant” failure (19% for MI < 5 group vs 36%) occurred less frequently in the MI < 5 group (P < 0.001). We conclude that “low Maruyama Index” surgery enhances regional control and survival but does not alter the occurrence of isolated distant metastases unassociated with regional failure. Our results speak to the substantial survival value of local-regional control in this disease.
