122 ng/mL, p = 0.06, trend toward significance) and after treatment (179 vs. 123 ng/mL, p = 0.02).
Statistical analysis using independent t -tests revealed that pre-treatment NGAL was greater in inoperable patients, but the difference approached significance: t = 1.93, p = 0.06; and post-treatment NGAL was significantly higher in inoperable patients: t = 2.37, p = 0.02.
Results : NGAL levels increased marginally during therapy (from 134 to 144 ng/mL; p = 0.28), but the rise was significant in inoperable patients ( p = 0.02) and increased with advanced FIGO stage, although this did not reach statistical significance ( p = 0.07).
The near-significant post-treatment p -value suggests a biological trend, which could be related to hypoxia, necrosis, or persistent inflammatory responses that are more common in advanced tumors.
