ABSTRACT
SUMMARY OBJECTIVE: Tumor budding is currently thought to be associated with worse prognosis. This study aims to examine tumor budding in invasive ductal-type breast carcinoma and its relationship with other clinicopathological parameters and overall survival. METHODS: All the H&E slides of 198 patients were re-evaluated for the histological grade, angiolymphatic invasion, perineural invasion, lymph node status, extranodal extension, multicentricity, pT, presence of the tumor budding, tumor budding score (i.e., low, intermediate, or high). Overall survival was considered the period after surgery until death. SPSS was used for statistical analysis. RESULTS: Tumor budding was identified in 98 (49.5%) patients. Tumor budding score was low in 41 (41.8%) of 98 cases, intermediate in 25 (25.5%), and high in 32 (32.7%). We determined a strong correlation between tumor budding and poor prognostic variables such as tumor size, pT stage, angiolymphatic invasion, perineural invasion, number of metastatic axillary lymph nodes, overall survival, and extranodal tumor extension in metastatic lymph nodes. This strong correlation was also present for the tumor budding score. CONCLUSION: Tumor budding may be a prognostic indicator for breast cancer.
ABSTRACT
SUMMARY OBJECTIVE Tumor budding is a parameter that is increasingly understood in colorectal carcinomas. We aimed to investigate the relationship between tumor budding, prognostic factors, and survival METHODS A total of 185 patients who had undergone colorectal surgery were observed. Tumor budding, the tumor budding score, and the relationship between these and prognostic factors, and survival investigated. RESULTS Tumor budding was found in 91 (49.2%) cases. The relationship between the tumor budding score and histological grade, lymphovascular invasion, perineural invasion, pathological lymph node stage, and mortality rates were significant. CONCLUSION In our study, the relationship between tumor budding and survival is very strong. Considering these findings and the literature, the prognostic significance of tumor budding becomes clear and should be stated in pathology reports.
RESUMO OBJETIVO Brotamento de tumor é um parâmetro que é cada vez mais conhecido em carcinomas colorretais. Nosso objetivo foi investigar a relação entre brotamento tumoral e fatores prognósticos e sobrevida. MÉTODOS Um total de 240 pacientes observados, submetidos à cirurgia colorretal. Brotamento de tumor, escore de brotamento tumoral e a relação entre estes e fatores prognósticos, sobrevida investigada. RESULTADOS Brotamento de tumores foi encontrado em 91 (49,2%) casos. A relação entre o escore de brotamento tumoral e o grau histológico, invasão linfovascular, invasão perineural, estadiamento linfonodal patológico e taxas de mortalidade foram significativas. CONCLUSÃO Em nosso estudo, a relação entre brotamento tumoral e sobrevida é muito forte. Em conjunto, todos esses achados e literatura são avaliados simultaneamente, o significado prognóstico da brotação do tumor é claramente visto e deve ser indicado nos relatórios de patologia.
