Introduction Our aim was to determine the relationship between surgical compliance and survival outcomes in patients with stage T1-2 non-small-cell lung cancer (NSCLC). Methods Patients with T1-2 NSCLC who were diagnosed between 2004 and 2015 were identified from the SEER database. Multivariate logistic regression was used to analyse factors associated with surgical compliance. Kaplan-Meier curves and Cox regression were used to analyse the effects of surgical compliance on overall survival (OS) and cancer-specific survival (CSS). Results Of the 221,704 eligible T1-2 NSCLC patients, 106,668 patients recommended surgery. Among them, 99,672 (93.4%) patients were surgical compliance group, and 6996 (6.6%) were surgical noncompliance group. Poor surgical compliance was associated with earlier diagnosis time, old age, male, black race, unmarried status, main bronchus site, poor grade/stage, and lower household income. Patients' compliance was an independent prognostic factor for OS and CSS of T1-2 NSCLC patients. Multivariate Cox regression showed that surgical noncompliance individuals showed lower OS (hazard ratio [HR] 2.494; 95% confidence interval [CI] 2.423-2.566, p less then 0.001) and lower CSS (HR 2.877; 95% CI 2.782-2.974, p less then 0.001) compared with surgical compliance patients. In addition, results in the non-surgical group were observed to be similar to those of the surgical noncompliance group. Conclusion We found that patients' compliance was an independent prognostic factor for survival in T1-2 NSCLC patients. Poor surgical compliance was associated with earlier diagnosis time, old age, male, black race, unmarried status, main bronchus site, poor grade/stage, and lower household income.Purpose Collecting duct carcinoma (CDC) is extremely rare and has high malignancy and poor prognosis. The purpose of this research is to explore the clinical characteristic, imaging, pathological diagnosis, treatment and prognostic outcome of CDCs. Materials and methods The clinical data of 12 CDC cases who had been surgically treated between August 2007 and August 2017 and verified the diagnosis of CDC by postoperative pathological and/or immunohistochemical staining (IHC) results were retrospectively analyzed, and related works of literature were reviewed. And Kaplan-Meier survival analysis was used to draw the survival curve and to calculate the survival rate and the median survival time. Results According to the TNM stage system, 4 cases were in stage I, 2 in stage II,3 in stage III, and 3 in stage IV. On the computed tomograph and magnetic resonance imaging, CDC displayed that various shapes, unclear boundary and invasive growth into the renal parenchyma. Compared with small CDCs which did not changbest way to treat CDC suspected by imaging examinations is radical surgery which can contribute to confirm the correct histopathological type. And post-operation follow-up is necessary.Background With a high frequency of 30%, KRAS mutations in patients with non-small cell lung cancer (NSCLC) often lead to their poor response to most anti-cancer therapies. As a multi-target tyrosine kinase inhibitor, Anlotinib shows clinical efficacy against several types of cancer. However, its effects on KRAS mutant NSCLC and the underlying molecular mechanisms remain unclear. Materials and methods Cell counting Kit-8 assay, colony formation assay, flow cytometry analysis, wound healing scratch assay, Transwell assay and xenograft mouse model were used to evaluate the anti-cancer effects of Anlotinib. The potential molecular mechanisms were determined by immunohistochemistry (IHC) and Western blotting. Results Anlotinib inhibited proliferation of KRAS mutant lung cancer cells and induced apoptosis in vitro. In addition, the migration and invasion abilities of these cells were also decreased after treatment with Anlotinib. Prednisolone F IL Receptor modulator It significantly suppressed tumor growth in vivo and prolonged the survival of the xenograft-bearing mice, which correlated to lower expression levels of Ki67 in the tumor tissues. Mechanistically, Anlotinib downregulated MEK and ERK as well as their phosphorylated forms in the KRAS mutant lung cancer cells. Conclusion Anlotinib inhibits the growth of KRAS mutant lung cancer cells partly via the suppression of the MEK/ERK pathway. Our findings provide novel insights into treating recalcitrant KRAS mutated NSCLC.Purpose Metastatic spinal cord compression (SCC) secondary to small cell lung cancer (SCLC) is a disastrous oncological emergency, but it is poorly understood due to the small numbers of patients and their short survival times. Whether patients suffered from SCC caused by metastatic SCLC benefit from spinal surgery remains unknown. The aim of this study was to evaluate the role of surgical treatment and prognostic factors in patients with SCC caused by metastatic SCLC. Methods From 2009 to 2019, 30 consecutive patients surgically treated for metastatic SCC from SCLC were enrolled in this retrospective analysis. Kaplan-Meier method and Cox regression analysis were used to estimate overall survival (OS) and identify prognostic factors. Quality of life (QoL) was assessed by the three-level EuroQol-five-Dimensions (EQ-5D-3L) instrument and compared using Student's t test. Results The median OS time was 9 months in our series. Relief of pain, preservation of neurological function, and improvement of performance status were achieved after surgical intervention. The mean EQ-5D-3L utility score showed a significant improvement after surgery (0.3394 preoperatively vs 0.5884 postoperatively). According to Cox regression analysis, postoperative ECOG-PS and immunotherapy were identified to be independent prognostic factors for patients with SCC caused by metastatic SCLC. Conclusion Despite the short life expectancy, prompt surgical decompression is extremely necessary for patients with SCC caused by SCLC, for surgery played a critical role in improving patients' QoL. Better performance status after surgery and receiving immunotherapy were associated with a longer OS.Background Cancer metastasis is the main obstacle to increasing the lifespan of cancer patients. Epithelial-to-mesenchymal transition (EMT) plays a significant role in oncogenic processes, including tumor invasion, intravasation, and micrometastasis formation, and is especially critical for cancer invasion and metastasis. The extracellular matrix (ECM) plays a crucial role in the occurrence of EMT corresponding to the change in adhesion between cells and matrices. Conclusion SPOCK1 is a critical regulator of the ECM and mediates EMT in cancer cells. This suggests an important role for SPOCK1 in tumorigenesis, migration and invasion. SPOCK1 is a critical regulator of some processes involved in cancer progression, including cancer cell proliferation, apoptosis and migration. Herein, the functions of SPOCK1 in cancer progression are expounded, revealing the association between SPOCK1 and EMT in cancer metastasis. SPOCK1 is a positive downstream regulator of transforming growth factor-β, and SPOCK1-mediated EMT regulates invasion and metastasis through the Wnt/β-catenin pathway and PI3K/Akt signaling pathway.
