The Relationship of GATA3 and Ki-67 With Histopathological Prognostic Parameters, Locoregional Recurrence and Disease-free Survival in Invasive Ductal Carcinoma of the Breast

Background: The aim of this study was to investigate the immunohistochemical expression of ribosomal protein (RP) S6-pS240 in non-special type invasive breast cancer in relation to other prognostic markers and gain new insights to facilitate more individualized treatment. Methods: The following clinical and histopathological parameters of 120 patients were determined: S6-pS240 expression, age, menopausal status, tumor size and grade, TNM stage, Nottingham Prognostic Index (NPI), lymph node stage, estrogen and progesterone receptor (ER/PR) expression, HER2/neu amplification, lymphovascular invasion, and proliferative index as measured by Ki-67. Treatment protocol and disease-free survival were evaluated accordingly. Results: Significant positive correlations were seen between S6-pS240 expression and Ki-67 values (rho = 0.530, p < 0.001), and NPI (rho = 0.370, p < 0.001) and HER2/neu amplification (rho = 0.368, p < 0.001). A negative correlation was found between S6-pS240 and ER/PR expression (rho = 0.362, p < 0.001). Patients with negative RP S6-pS240 expression had significantly longer disease-free survival (log-rank test, p = 0.005). Conclusion: Immunohistochemical analysis of RP S6-pS240 is a valuable additional prognostic marker in patients with invasive breast cancer. Routine use of S6-pS240 immunohistochemistry is recommended.

L1cam Expression

Introduction: Endometrial adenocarcinoma is characterized by a good prognosis. However, the disease response shows a significant heterogeneity. Treatment of endometrial cancer (EC) is still based on clinico-pathological parameters, which have limited role in risk stratification. There is a need for more determinant markers, such as L1 Cell Adhesion Molecule (L1CAM), to identify patients at higher risk of relapse and tailor a more convenient treatment. L1CAM has a capacity to enhance cell motility and promote tumor invasion in different malignancies. In Egypt, the incidence rate of EC is growing over time. Especially in Elgharbiah governorate (home of this study). L1CAM expression and Ki-67 was reported and compared with other clinico-pathological criteria. Method: Seventy-six female patients of endometrial carcinomas were involved in this prospective study. The patients were treated and followed up at Tanta University Hospitals in the period between January 2015 to April 2019. L1CAM expression and Ki-67 was detected by immuno-histochemical exam and compared with other clinico-pathological criteria. Survival was assessed and compared by Kaplan-Meier curves and log-rank test. Results: Positive L1CAM expression was detected in 17 patients (22.4%) and was significantly correlated with unfavorable prognostic factors such as higher stage and grade ( P= 0.021 and P =0.001 respectively), lympo-vascular invasion ( P <0.001), non-endometroid type ( P <0.027) and Ki-67 ( P= 0.003). Univariate analysis revealed that: positive L1CAM; higher tumor grade; high stage; and non-endometrioid type were significantly associated with shorter disease-free survival (DFS) but no significant correlation was detected between Ki-67 and DFS. In multivariate analysis, positive L1CAM remained statistically significant with DFS [P =0.045; 95%CI (1.028:11.17); HR=3.38]. Conclusion: Our study indicates that L1CAM expression and Ki-67 are significantly associated with poor tumor characteristics. L1CAM is significantly associated with shorter disease-free survival and may be a helpful tool as a part of a simple clinical molecular classification for EC.

PURPOSE In addition to tumor size, grade, location, and the presence of metastases, other factors may be useful in prognostication for adults with soft tissue sarcoma (STS). This study examines the relationship of MDR-1 mRNA, p-glycoprotein (P-gp), Ki-67 expression, and DNA content expression to clinical outcome in adults with STS. PATIENTS AND METHODS Snap-frozen STS specimens from 65 patients were analyzed and compared with clinical outcomes. Immunohistochemistry was performed for the Ki-67 antigen and P-gp. DNA content was determined using the Feulgen reaction and quantitated using image analysis. MDR-1 mRNA expression was determined using a reverse-transcriptase polymerase chain reaction (RT-PCR)-based assay. RESULTS P-glycoprotein expression was found by immunohistochemistry in 48% of cases with 5-year overall (54% v 14%, P = .07) and disease-free survival rates (32% v 18%, P = .039) higher in high-grade tumors that did not express P-gp. MDR-1 mRNA was detected in 51% of cases and no patient with high levels of MDR-1 mRNA expression was a long-term survivor. Patients with diploid tumors had significantly better survival than those with nondiploid tumors (51% v 31%, P = .03). High levels of Ki-67 were associated with poorer overall survival (46% v 31%, P = .04). On multivariate analysis, American Joint Committee on Cancer (AJCC) staging, DNA content, Ki-67, and P-gp staining were significant prognostic factors for 5-year overall and disease-free survival. CONCLUSION P-gp expression, high-level Ki-67 expression, and nondiploid DNA content are independent prognostic indicators that correlate with poor outcomes in STS patients. However, MDR-1 mRNA was not found to be predictive of survival. These newer markers are useful additions to AJCC staging for prognostication for patients with STS. Such markers may be useful in selecting high-risk STS patients who could benefit from systemic adjuvant therapy.
