Development of clinico-histopathological predictive model for the assessment of metastatic risk of oral squamous cell carcinoma

In the article titled “Development of clinico-histopathological predictive model for the assessment of metastatic risk of oral squamous cell carcinoma”, published in article number 2, issue 1, Volume 19 of Journal of Carcinogenesis,^[1] there are minor errors on page no. 2, paragraph number 4, under methods section. It is currently published as “Single cells or tiny groups of about five or more cells scattered at the ITF were considered as tumor buds. They were graded as low and high based on <5 buds and ≥5 buds, respectively at ×20.^[8] Cytoplasmic pseudofragments were identified as non-nucleated, smoothly contoured fragments that were uniformly positively stained for cytokeratin. Based on the number of fragments/field in ×20, they were categorized into low (0–9 fragments) and high grades (≥10 fragments).^[9]”

The correct paragraph should be read as “Single cells or tiny groups of about five or more cells scattered at the ITF were considered as tumor buds. They were graded as low and high based on <10 buds and ≥10 buds, respectively at ×200.^[8] Cytoplasmic pseudofragments were identified as non-nucleated, smoothly contoured fragments that were uniformly positively stained for cytokeratin. Based on the number of fragments/field in ×200, they were categorized into low (0–9 fragments) and high grades (≥10 fragments).^[9]”
