Background/Aim. The histological phenomenon of tumor budding is being
recognized as an important determinant of disease progression and poor
prognosis in various types of carcinoma. We aimed to evaluate the
clinicopathological significance of tumor budding in adenocarcinoma of the
lung. Methods. The study included 114 patients, operatively treated for lung
adenocarcinoma in one-year period. Microscopic analysis of routine
histological slides was performed to establish the presence and density of
tumor buds. These results were compared to gender, age, tumor size, nodal
status and pathological stage. Results. The budding-positive group included
34 men (53.1%) and 27 women (54%). There were 30 men (46.9%) and 23 women
(46%) in the budding-negative group. There was no statistical significance
found between males (64.3 ± 6.59) and females (63.1 ± 6.53) in the
budding-positive group, nor in the budding-negative group (males 63.3 ±
6.02; females 63.2 ± 6.72), age considering. Statistically significant
result in tumor size was found in females with the presence of tumor budding
(p<0.05). Budding-positive group of patients in nodal status N1 and in stage
III of the disease pointed to the statistical significance (p<0.05).
Conclusion. With statistical significance confirmed between higher nodal
status, higher pathological stage and tumor budding found in this study,
this histological phenomenon is still relatively new for diagnostics domain
of pathology, but receiving increasing attention as an adverse prognostic
factor. These results may help tumor budding to incorporate into existing
staging systems as it is associated with other factors known to portend
worse outcome.
