Noble at el reported the NUn score for predicting complications following esophageal resection. This can help to identify a patient who may benefit from more aggressive management. The authors are from the South Coast Cancer Collaboration-Oesophago-Gastric (SC-OG). The name of the score may be derived from the names of two of the authors.
Patient selection: esophageal resection
Outcome: major complications including anastomotic leak and death
• A low albumin is usually associated with worst prognosis. This score seems to say that a high albumin is worse.
Interpretation:
• A score > 10 was associated with major complications.
Performance:
• The score was found to have a sensitivity of 95% and specificity of 49% (detected most cases but had a high false positive rate) with a diagnostic accuracy of 0.801.
• Findlay et al performed a validation study and did not think that the score showed clinical utility.
