Tumor Budding is an Independent Prognostic Factor to Predict Overall Survival in Endometrial Endometrioid Carcinoma: A Retrospective Study

Abstract

Objective. Tumor budding defined as a tumor cell nest away from the main tumor, has been found to be associated with prognostic parameters in many cancer types. We aimed to investigate the relationship between tumor budding and clinicopathological parameters in endometrioid endometrial carcinomas, as well as its prognostic importance. Materials and Methods. One hundred four patients who underwent surgical resection with diagnosis of endometrioid endometrial carcinomas between June 2011 and May 2020 were included. The area where tumor budding was the most prominent was determined, and tumor budding was counted from hematoxylin and eosin-stained section at one high power field (X 200). By performing ROC analysis, the cut off value was obtained in order to divide the patients into low and high tumor budding groups. Results. The cut off value was determined as 1/0.95 mm2 according to the ROC analysis. Tumor budding was observed in 24 (23%) patients. Tumor budding significantly associated with poor overall survival ( P < .001), distant metastasis ( P = .001), presence of angiolymphatic invasion ( P < .001), lymph node metastasis ( P = .024), cervical invasion ( P < .001), high FIGO grade ( P < .001), large tumor size ( P = .004). In multivarate analysis, tumor budding and age were found to be an independent risk factor for overall survival ( P = .003, P = .014 respectively). Conclusion. Tumor budding is a significant morphological parameter independent of other prognostic parameters in endometrioid endometrial carcinomas. Standardizing the assesment and scoring of tumor budding, as well as including this entity in routine pathology reports could light the way for ideas in the risk analysis of patients.

New Tumor Budding Evaluation in Head and Neck Squamous Cell Carcinomas

“…TB has already been investigated in many tumors (colon carcinoma, gastric cancer, urothelial carcinoma, pancreatic carcinoma, breast cancer, endometrial carcinoma, lung cancer, esophageal cancer, liver cancer) [4][5][6][7][8][9][10][11][12]. In many tumors, the TB score is associated with a worse prognosis [13][14][15][16][17][18].…”

“…Furthermore, while Qi et al analyzed a grading scheme composed of TB and the "microcystic, elongated, fragmented" (MELF) pattern and obtained the worst outcomes for patients whose tumors show both TB and MELF; analysis was conducted irrespective of TCGA-defined molecular subgroups [20]. The same issue is a limitation of a recent study by Okcu et al [21].…”
