Excerpt
We read with much interest the article by Milovanov et al. that was recently published in
Annals of Surgical Oncology. 1 The authors reported an external validation of a simple scoring system we had previously published for determining the likelihood of a complete cytoreduction in patients with low-grade mucinous adenocarcinoma of the appendix (the SPAAT score).
2 In this external validation, there was a notable difference in the positive predictive value (PPV) of the SPAAT score compared with our original publication (50% vs. 95%). In addition, the authors noted a negative predictive value (NPV) of 90%, indicating that a SPAAT score ≥ 3 predicted failure to achieve a complete cytoreduction. The authors conclude that the SPAAT score has limited clinical utility due to low sensitivity and PPV. …
