Chronic inflammation contributes to malignant conversion and metastasis in GBC. Expression of inflammatory proteins, such as signal transducer and activator of transcription factor (STAT) and nuclear factor kappa B (NF\u0138B) proteins, for diagnosis through immunohistochemistry (IHC) is a promising area of research; however, diagnosis of GBC through IHC-based methods is still in its infancy. So, the present pilot study explores the use of STAT proteins (STAT 3 and 6) and NF\u0138B as diagnostic biomarkers for GBC.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>Histologically confirmed cases of GBC (n=13) and cholelithiasis (n=23) as controls, were recruited. IHC was performed for protein expression of STAT3, STAT6, and NF\u0138B. Subgrouping into high and low expression was performed based on the receiver operating curve (ROC) analysis. Diagnostic utility and its association with the aggressiveness of cancer were assessed.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>The mean age of GBC and cholelithiasis patients was 50.84\u00b114.5 and 44.0\u00b111.9 years, respectively. Liver infiltration and metastasis were observed in 61 per cent and 69 per cent of the patients, respectively. STAT3, STAT6, and NF\u0138B expressions were significantly higher in GBC as compared to cholelithiasis. Sensitivity and specificity for STAT3 and STAT6 were 91, 47 and 75, 39 per cent, respectively. STAT6 expression was associated with lymph node involvement. Whereas, both STAT3 and STAT6 expressions were associated with Liver infiltration.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Interpretation &amp; conclusions<\/jats:title>\n<jats:p>This pilot study demonstrated STAT3 and STAT6 as sensitive and specific molecular biomarkers for diagnosing and assessing the aggressiveness of GBC. These may be used as an adjunct to the diagnosis of GBC after validation on a larger sample
