The Prognostic Significance of Tumor Budding and Tumor-Infiltrating Lymphocytes in Patients Diagnosed With Malignant Melanoma.

The tumor microenvironment plays a critical role in malignant melanoma, influencing progression and patient outcomes, particularly through tumor budding (TB) and tumor-infiltrating lymphocytes (TILs). Despite the importance of TB, its detailed impact still needs to be explored, especially its interaction with TILs. This study evaluates the prognostic significance of TB and TILs in malignant melanoma, assessing their potential as indicators for disease progression and survival.

Prognostic significance of tumor budding, desmoplastic reaction, and lymphocytic infiltration in patients with gastric adenocarcinoma.

Background: Recent studies have shown that the tumor microenvironment significantly influences the behavior of solid tumors. In this context, Accumulated data suggests that pathological evaluation of tumor budding (TB), desmoplastic reaction (DR), and tumor-infiltrating lymphocytes (TILs) may be crucial in determining tumor behavior in the gastrointestinal tract. Regarding gastric adenocarcinoma (GAC), although some results suggest that TB and TILs may be effective in determining the course of the disease, the data do not agree.

Clinicopathologic Evaluation of CD80, CD86, and PD-L1 Expressions with Immunohistochemical Methods in Malignant Melanoma Patients.

Objective: Diagnostic and prognostic biomarkers for malignant melanoma are crucial for treatment and for developing targeted therapies. Malignant melanoma is a highly immunogenic tumor, and its regression, treatment, and prognostic evaluation are directly related to escape from immune destruction. Therefore, we aimed to determine the expression levels of CD80, CD86, and PD -L1 in malignant melanoma tissue samples by immunohistochemistry and to investigate the possible relationship between these proteins and the clinicopathological features in this study.
