14548 Background: Despite several studies have evaluated the role of prognostic factors (PF) in metastatic colorectal cancer, results are controversial. The aim of the present study was to assess PF in a homogeneous population with MCCID treated with biochemical modulation of 5- Fluorouracil-based regimens. Methods: Analyses were based on individual data of 318 patients (P) with MCCID treated in different prospective trials at GOCS Institutions since May 1984 to Jun 2001. The following variables (V) were considered: a) Clinical variables (CV): age, sex, family history of CC, hypertension, diabetes, tabaquism, weight loss, and performance status (PS), b) Tumor variables (TV): histologic grade, size and location of primary tumor; number of metastatic sites, number and size of liver metastases, uni- bilateral liver involvement; and c) Laboratory variables (LV): CEA, lactate dehydrogenase (LDH), alkaline phosphatase, ALT, AST, and hemoglobin. Overall survival (OS) was analyzed since date of diagnosis by means of Kaplan-Meier and the Log-rank test was used to assess the differences. A Cox’s proportional hazard modeling was used for multivariate analyses. Results: The OS for the entire group was 18.1 months (IC95, 15.0–22.7). Univariate analysis showed statistical significance in the following; a) CV: family history CC (p=0.001), PS (p=0.04), diabetes (P=0.003); b) TV: histologic grade (p=0.01), uni-bilateral liver involvement (p<0.0001), number of liver metastases (p<0.0001) and size of liver metastases (p<0.0001); and c) LV: hemoglobin (p=0.05), ALT (P=0.0006), AST (p<0.0001), alkaline phosphatase (p<0.0001), LDH (p=0.0004); Cox’s analyses showed statistical significance only for PS and alkaline phosphatase (p= 0.01 and p=0.0001, respectively). Conclusions: In this setting of P with MCCID the PS remains the most important PF for OS. High value of alkaline phosphatase may reflect liver involvement. No others PF considered in the analyses had prognostic influence. No significant financial relationships to disclose.

Background: In the last 10 years, the management of patients with gastric cancer liver metastases (GCLM) has changed from chemotherapy alone, towards a multidisciplinary treatment with liver surgery playing a leading role. The aim of this systematic review and meta-analysis is to assess the efficacy of hepatectomy for GCLM and to analyze the impact of related prognostic factors on long-term outcomes. Methods: The databases PubMed (Medline), EMBASE, and Google Scholar were searched for relevant articles from January 2010 to September 2020. We included prospective and retrospective studies that reported the outcomes after hepatectomy for GCLM. A systematic review of the literature and meta-analysis of prognostic factors was performed. Results: We included 40 studies, including 1573 participants who underwent hepatic resection for GCLM. Post-operative morbidity and 30-day mortality rates were 24.7% and 1.6%, respectively. One-year, 3-years, and 5-years overall survival (OS) were 72%, 37%, and 26%, respectively. The 1-year, 3-years, and 5-years disease-free survival (DFS) were 44%, 24%, and 22%, respectively. Well-moderately differentiated tumors, pT1–2 and pN0–1 adenocarcinoma, R0 resection, the presence of solitary metastasis, unilobar metastases, metachronous metastasis, and chemotherapy were all strongly positively associated to better OS and DFS. Conclusion: In the present study, we demonstrated that hepatectomy for GCLM is feasible and provides benefits in terms of long-term survival. Identification of patient subgroups that could benefit from surgical treatment is mandatory in a multidisciplinary setting.

CONTEXT: Search of tumors markers that allow treatment with higher survival rates, and indicate the response to treatment and recurrence of cancer OBJECTIVE: To analyze the immunoexpression of the proteins p53, bcl-2 and Ki-67 in colorectal adenocarcinoma and correlate them with the clinical-pathological prognostic factors. METHOD: Tissue microarray paraffin blocks were made from colorectal adenocarcinoma tissue resected from 82 patients who had undergone surgery but not chemotherapy or radiotherapy, at "Hospital São Paulo", São Paulo, SP, Brazil, between 2002 and 2005. Thin sections (4 µm) were subjected to immunohistochemical reactions, and immunoexpression staining scores were obtained. The scores were correlated with the degree of cell differentiation, staging, disease-free interval, recurrence, survival and specific mortality. The study variables were analyzed using the chi-square and Kaplan-Meier tests to investigate associations with the markers. The significance of the differences between the curves of the disease-free interval and survival was analyzed using the Logrank and Wilcoxon tests. RESULTS: The immunohistochemical expression of p53 was positive in 70 tumors (85.4%) and negative in 12 (14.6%). The expression of bcl-2 was positive in 26 (31.7%) and negative in 56 (68.3%). The expression of Ki-67 was positive in 62 (75.6%) and negative in 20 (24.4%). There was no statistically significant correlation between the expressions of these markers separately or in conjunction, in relation to the degree of cell differentiation, staging, disease-free interval, survival and specific mortality. In relation to recurrence, there was a statistically significant correlation with positive expression of Ki-67 (P = 0.035). CONCLUSION: The immunohistochemical expression of Ki-67 in colorectal cancer is associated with recurrence of this disease.

Context: Breast cancer (BC) is the most common cancer in women worldwide. Hereditary susceptibility created by mutations in autosomal dominant genes is responsible for 5 to 10% of all BC cases in women. Recent studies have identified genes associated with increased risk for aggressive BC, providing the basis for better risk management. Evidence Acquisition: The latest information in National Center for Biotechnology Information (NCBI), Google Scholar, ScienceDirect, and Scopus were the main databases for finding articles. A combination of keywords of ‘metastasis’, ‘invasion’, ‘aggressive breast cancer’, ‘prognostic factor’, ‘mutation’, and ‘cancer treatment’ was searched in the databases to identify related articles. Titles and abstracts of the articles were studied to choose the right articles. Results: Mutations in breast cancer type 1 susceptibility protein (BRCA1) and breast cancer type 2 susceptibility protein (BRCA2) genes are two central players related to the high risk of BC. Mutation in tumor protein p53 (TP53) is another important mutation that leads to triple-negative BC. Although the majority of BC types are not associated with high-throughput mutant genes such as BRCA1, BRCA2, and TP53, they are associated with low-throughput genes, including DNA repair protein Rad50 (RAD50), Nijmegen breakage syndrome gene (NBS1), checkpoint kinase 2 (CHEK2), BRCA1-interacting protein 1 (BRIP1), E-cadherin gene (CDH1) and PALB2, UCHL1, aldehydedehydrogenase1A3 (ALDH1A3), androgen receptor (AR), 5-bisphosphate 3-kinase (PIK3CA), phosphatidylinositol-4, and luminal gene expression that are generally mutated in the global population. High tumor mutational burden (TMB) was associated with improved progression-free survival. Conclusions: The lymph node status, early tumor size, ER, PR, human epidermal growth factor receptor-2 (HER2), and Ki-67 are conventional prognostic factors for BC. However, these factors cannot exactly predict the aggressive behavior of BC. Hence, in this review, we discussed new prognostic factors of aggressive BCs that are useful for the treatment of patients with BC.

Background:Well-differentiated pancreatic neuroendocrine tumors (pNETs) represent a group of rare epithelial neoplasms with a highly variable clinical course. AKT1 is one of the most frequently activated protein kinases in pNETs, which promotes the tumor growth and is of interest as a prognostic factor and a target for new treatment approaches.Aim:To study the expression of the phosphorylated variant of AKT1-kinase (p-AKT1) in primary pNETs and their liver metastases and to correlate the results with various clinical and pathological parameters and the disease prognosis.Materials and methods:P-AKT1 expression was studied by the immunohistochemical analysis of the primary lesions and liver metastases in 52 pNETs patients.Results:A high level of cytoplasmic and/or nuclear immunoreactivity was detected in 24/52 of the primary pNETs (46.2%) and in 16/27 of their liver metastases (59.3%). p-AKT1 expression was observed in 3 (21.4%) of NET grade (G) 1, in 14 (46.7%) of NET G2, and in 7 (87.5%) of NET G3. p-AKT1 expression was more frequently identified in pNET G3 category and increased during the tumor progression in metachronous liver metastases, as compared to the corresponding primary tumor. In addition, p-AKT1 positivity was significantly associated with an increase of grade from G1 to G3 (p = 0.004), the Ki-67 index (p = 0.029), the pTNM stage (p = 0.0008), perineural invasion (p = 0.031) and a decrease in disease-free survival (p = 0.05).Conclusion:The results suggest that p-АКТ1 plays an important role in the pathogenesis of pNETs and may be an additional criterion for assessment of the prognosis and treatment effectiveness in this type of tumors.
