Prognostic Factors in Operated Early Stage Lung Cancer Patients- Retrospective Single Center Data

Aim: Non-small cell lung cancer (NSCLC) accounts for 85% of all lung cancers. Although curative treatment is surgery in the early stages, disease relapse is common. In this study, we retrospectively evaluated the prognostic factors and outcomes of operated NSCLC cases.Materials and Methods: Retrospective analysis of data from 166 patients with early stage NSCLC who presented after surgery and treated and followed in our clinic between 2006-2018 was performed. Histopathologic features and clinical findings were investigated as prognostic factors.The findings were analyzed using SPSS.Results: At the time of diagnosis, median age was 61 (39-82) and 84% of the patients were male. Most common pathologic subtype was adenocarcinoma. Median disease free survival (DFS) and overall survival (OS) were 76 months (%95CI:32.1-110.0) and 87 months (95%CI:59.8-114.1). ). In multivariate analysis, presence of vascular invasion was found to be independent prognostic factors for both DFS and OS (HR:2.5 and 2.3, respectively). Adenocarcinoma solid pattern was only associated with worse disease-free survival (HR: 1.7).Conclusion: In our study, we showed that the presence of vascular invasion and solid-type adenocarcinoma is associated with poor survival

Prognostic significance of ADAM17 expression in patients with gastric cancer who underwent curative gastrectomy

WOS: 000358156300004PubMed ID: 25786367A disintegrin and metalloproteinase (ADAM) 17 has been indicated to be an indispensable regulator of cellular events from proliferation to migration. Although prognostic importance of ADAM17 expression has been investigated in several tumours, its clinical utility as a useful prognostic molecular marker remains unclear in gastric cancer. In the current study, we evaluated the expression of ADAM17 and its prognostic significance in gastric cancer patients after curative gastrectomy. The prognostic significance of ADAM17 expression was analysed immunohistochemically in 156 patients with gastric cancer who had undergone curative gastrectomy, and the relationship between its expression and clinicopathological factors was also evaluated. High ADAM17 expression was detected in 79 patients (51 %), whereas low expression was found in 77 cases (49 %). There was significant correlation between gender, histology, lymph node metastasis, vascular invasion, the presence of recurrence and high ADAM17 expression. Recurrence in patients with high ADAM17 expression was significantly higher than that for patients with low ADAM17 expression (p = 0.032). The median disease-free survival (DFS) time for patients with tumours with high ADAM17 expression was worse than that of patients with tumours with low ADAM17 expression (16.6 vs. 44.2 months, p = 0.004). In addition, patients with low ADAM17 expression had a higher median overall survival (OS) (49.6 vs. 26.9 months, p = 0.019) compared to those with high ADAM17 expression. Multivariate analysis indicated that the rate of ADAM17 expression was an independent prognostic factor for DFS, in addition to the already known important clinicopathological prognostic indicator. But the prognostic importance of ADAM17 expression could not be proved by multivariate analysis for OS. The potential value of ADAM17 expression as a useful molecular marker in gastric cancer progression should be evaluated comprehensively; it may predict recurrence and poor prognosis in patients with gastric cancer after curative resection
