Objective:
To analyze the impact of clinico-pathological prognostic factors on survival in patients with GBC OSCC. To evaluate the association between various clino-pathological and treatment factors influencing the 3-year and 5-year Overall survival (OS), and Disease specific survival (DSS) in patients with lower GBC OSCC.
Patients & Methods:
An Institutional Ethical Committee (IEC) approved retrospective chart audit was performed. Biopsy proven squamous cell cancer of gingivobuccal complex (GBC OSCC) patients from 2010 to 2019 who were treated primarily with surgery with or without adjuvant therapy having complete clinicopathological and follow up data were included. Survival outcomes including 2-year, 3-year & 5-year OS, and DSS were calculated and analyzed. A multivariate analysis was performed to identify significant predictor for the survival outcomes. A p-value < 0.05 was considered significant.
Results:
183 patients with primary OSCC were identified out of which 83 patients comprised of OSCC of lower GBC. Age (p < 0.001), tumor grade (p = 0.009), pN status (p = 0.002), PNI (p < 0.001), lymph node metastasis (p = 0.002), treatment given (p = 0.02) and adjuvant therapy (p = 0.02) were found as a significant prognostic factor in univariate analysis.
Conclusion:
The OS & DSS of the patients with lower GBC SCC is 78.3%. The 2-year, 3-year, and 5-year OS of the study population was reported to be 95.2%, 87.9%, and 78.8% respectively. PNI & lymph node metastasis were significant prognostic factor for OS with an adjusted hazard ratio 4.91 and 7.75 respectively.

Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
