- Gastric cancer molecular classification and adjuvant therapy: Is there a different benefit according to the subtype?(2020) RAMOS, Marcus F. K. P.; PEREIRA, Marina A.; AMORIM, Larissa C.; MELLO, Evandro S. de; FARAJ, Sheila F.; JR, Ulysses Ribeiro; HOFF, Paulo M. G.; CECCONELLO, Ivan; CASTRIA, Tiago B. deBackground Gastric cancer (GC) has been defined in distinct molecular subtypes with different therapeutic implications. However, its clinical significance and prognosis regarding standard chemotherapy (CMT) remains unclear. This study aimed to analyze the impact of perioperative or adjuvant treatment among subtypes of GC. Methods We retrospectively evaluated all stage II/III patients with GC who underwent a curative gastrectomy. Based on immunohistochemistry and in situ hybridization techniques, GC was classified into five subtypes: Epstein-Barr virus (EBV) positive, microsatellite instability (MSI), e-cadherin aberrant, p53-aberrant, and p53-normal. Results Among the 178 CG included, 111 patients received CMT and 67 were treated with surgery alone. Survival analysis showed that p53-aberrant GC treated with CMT had better disease-free survival (DFS) compared with surgery alone (P = .001).There was no significant difference in DFS between patients who received CMT and those with surgery alone for EBV, MSI, E-cadherin, and p53-normal GC. An improvement in overall survival was observed only for E-cadherin (P = .001) and p53-aberrant (P < .001) patients who received CMT. Conclusions CMT showed different impact on the survival of CG according to the molecular subtype. No survival benefit was observed for EBV and MSI groups who received CMT. GC with p53-aberrant had a significant benefit in survival with standard therapy.
- Prognostic Value of Systemic Inflammatory Biomarkers in Patients with Metastatic Renal Cell Carcinoma(2020) MARTA, Guilherme Nader; VELHO, Pedro Isaacsson; BONADIO, Renata R. C.; NARDO, Mirella; FARAJ, Sheila F.; SOUZA, Manoel Carlos L. de Azevedo; MUNIZ, David Q. B.; BASTOS, Diogo Assed; DZIK, CarlosMetastatic renal cell carcinoma (mRCC) encompasses a heterogeneous group of neoplasms with distinct clinical behavior and prognoses. As a result of the increasing number of therapeutic options in the metastatic setting, it is crucial to improve prognostic stratification ability. We aimed to evaluate the prognostic value of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and combination platelet count and neutrophil lymphocyte ratio (COP-NLR) in patients with mRCC. We evaluated a cohort of mRCC patients treated with first-line pazopanib or sunitinib. Levels of NLR, PLR and COP-NLR were measured prior to systemic treatment and evaluated as prognostic predictors. Primary endpoint was overall survival (OS). Data from 276 patients were included, of which 54.7% received first-line pazopanib and 45.3%, sunitinib. Memorial Sloan-Kettering Cancer Center risk classification was intermediate and poor in 50% and 42.6% of patients, respectively. High NLR (> 3.5) was associated with inferior OS (median 9.6 vs 17.8 months,P < 0.001). A high PLR (> 200) was associated with inferior OS (median 10.3 vs 17 months,P = 0.002). The median OS in the COP-NLR 1, 2 and 3 groups were 19.0 months (95% CI 15.3-26.0), 13.1 months (95% CI 9.8-17.0) and 7.4 months (95% CI 3.6-11.9), respectively (P < 0.001). In the multivariate analysis, high NLR and high COP-NLR were associated with inferior OS. Both high NLR and high COP-NLR were associated with poorer OS in our cohort of patients with mRCC treated with first-line pazopanib or sunitinib.
