ObjectiveTo investigate the association between clinicopathological findings and tumor stage according to AJCC 2018 guidelines in patients suffering from Oral squamous cell carcinoma (OSCC).MethodsA descriptive study was conducted from January 2019 to January 2020 at King Edward Medical University and University of Health Sciences on a total of 49 patients enrolled after obtaining written informed consent. Clinical and radiographic findings were recorded. Pathological reporting was done using AJCC 2018 cancer staging guidelines. Association between clinicopathological features with tumor stage and grade was assessed using Chi-square and Kruskal-Wallis test.ResultMean age of the patients was 46.1 ± 10.6 years. Most of the tumors were of well differentiated type (49%) and moderately differentiated (40.8%) with predominant clinical stage III in 42.9% & IV in 44.9 % and primary tumor stage pT2 28.6% & pT3 36.7%. Significant difference was seen for primary tumor stage in relation to age, gender, depth of invasion, primary site, and size of tumor (p < 0.01). For clinical stages, significant difference was observed in the age, gender, size of tumor, nodal metastasis, and anatomical tumor site (p < 0.01).ConclusionApplication of 8th Edition AJCC guidelines identifies the importance of the latest classification with strong association of latest stage criteria with age, gender, site of primary tumor, tumor thickness, depth of invasion, nodal metastasis and size of largest lymph node involved, and Level of Lymph node involved (level III & V) in a subset of patients from a developing country.Copyright: © Pakistan Journal of Medical Sciences.
