Implication

Descriptive study compares PET-CT and invasive results for lymph nodes in lung cancer, suggesting staging implications.

Key Points

To compare the effectiveness of PET-CT versus invasive approaches in staging mediastinal lymph nodes in lung cancer patients.
Descriptive study involving 100 lung cancer cases diagnosed between January 2015 and March 2022.
Assessment of mediastinal lymph nodes using PET-CT and invasive methods.
Determination of consistency of PET-CT through percentage consistency method.
PET-CT sensitivity for mediastinal staging: 85%.
Specificity: 75%, with a false positive rate of 25% and a false negative rate of 15%.
Positive predictive value: 70%, negative predictive value: 88%, and accuracy rate: 79%.
