Abstract
Introduction: Tumor Budding has emerged as a promising indicator of prognosis in various carcinomas of the body. Since it is a H&E feature,
its evaluation can and should be included in pathology reports wherever feasible.
Aims: The aim of this study is to analyze the correlation of tumor budding with various prognostic factors of esophageal squamous cell
carcinomas.
Method and Results: Sixty-one cases of esophageal resections reported as squamous cell carcinoma at Shaukat Khanum Memorial Cancer
Hospital and Research Centre between 2018 and 2019 were reviewed for tumor budding. Budding was classified into high (10 or more buds),
intermediate (5 to 9 buds) and low (4 and less) bud groups. Each group was then correlated with lympho-vascular invasion, pN, pT stages, grade
of the tumor and 1-year survival. P values were obtained from chi square tests (significant if less than 0.05) and showed statistical significance
of tumor budding with tumor grade (p= 0.02), lympho-vascular invasion (p= 0.0004) and pN stage (p= 0.03). Survival graphs were plotted using
Kaplan Meier plot in SPSS software.
Conclusion: A higher bud group is a promising predictor of poor prognosis in esophageal squamous cell carcinomas and can assist in the
planning of treatment in the patients.

Introduction
Squamous cell carcinoma constitutes 90% of all the tumors
in esophagus. It is the sixth most common cancer diagnosed and
treated at Shaukat Khanum Hospital, Lahore, Pakistan. The current
practice of estimating prognosis in these patients utilizes the
grade and stage of tumor as determined by the AJCC TNM system,
however, the search for better and more reliable prognostic
markers continue. Tumor budding is one of the emerging and
promising prognostic markers which is currently being studied
in several carcinomas. A higher bud group has been reported to
confer an adverse prognosis. In this study, we aim to correlate
tumor budding with pT, pN, lympho-vascular invasion, grade
of tumor and prognosis in patients diagnosed with esophageal
squamous cell carcinoma at Shaukat Khanum Hospital, Lahore.
Materials and Methods
Ethical issues
The Institutional Review Board Approval was taken (IRB# EX-
28-05-20-02).
Case selection
Sixty-one esophageal resections grossed at Shaukat Khanum
Memorial Cancer Hospital and Research Centre, Lahore, Pakistan
from January 2018 to December 2019 were included in the study.
These excluded cases of review originally grossed outside the
hospital, and cases with suboptimal fixation. The blocks were
fixed in 10% buffered formalin and embedded in paraffin. The
tissues were then sectioned at 0.5um thickness and stained with
