No significant differences in cardiopulmonary bypass time, aortic cross-clamp time, overall operative time, perioperative mortality, or complications were observed between two-port and three-port totally thoracoscopic mitral valve replacement. Two-port totally thoracoscopic mitral valve replacement is a safe, effective, and feasible procedure for mitral valve replacement.
Permanent pacemaker implantation (PPI) is widely used for the treatment of chronic arrhythmia. The aim of the present study was to investigate the incidence of postoperative complications and the risk factors in patients with PPI.

The clinical data of 124 patients who underwent PPI in our hospital from January 2014 to January 2018 were collected and analyzed retrospectively. Data on sex, age, status of disease, and related complications of all patients were recorded, and differences were compared. The factors affecting postoperative complications in patients with PPI were analyzed.

The incidence of postoperative complications in 124 patients with PPI was 8.06% (10/124), including 4 cases with capsular hematoma (3.23%), 2 cases with capsular rupture (1.61%), 3 cases with capsular infection (2.42%) and 1 case with venous thrombosis (0.81%). Unconditional single-factor logistic regression model showed that the incidence of postoperative complications in patients with PPI was significantly greater with oldeostoperative complications in patients with PPI.
Esophageal cancer represents a major health threat in China. Esophagectomy is the standard treatment for respectable esophageal cancer. This study aimed to investigate the costs of hospitalization in esophageal cancer patients undergoing esophagectomy, and to analyze the factors influencing these costs.

A retrospective observational study which enrolled 196 patients who underwent esophagectomy from September, 2018, to April, 2019, in the Affiliated Cancer Hospital of Zhengzhou University were conducted.

The median inpatient cost was ￥72,772 (range, ￥49,796-128,771). Materials accounted for 39.7% of the direct medical costs, which was the highest proportion for any of the cost components. Minimally invasive esophagectomy (MIE, OR 0.031; 95% CI 0.005-0.209), cardiopathy comorbidity (OR 0.344; 95% CI 0.136-0.872), and anastomotic leak (OR 0.012; 95% CI 0.001-0.131) were risk factors for higher cost, while early oral feeding (OR 3.979; 95% CI 1.430-11.067) was a protective factor.

Understanding the factors associated with high hospitalization costs will help to reduce healthcare expenditure. By controlling complications and promoting early oral feeding, the economic burden on esophagectomy patients can be relieved. Further research based on a longitudinal design is needed to investigate the full costs of hospitalization associated with esophageal cancer.

Cough is one of the shared complications after lung surgery. In this study, a prospective analysis was conducted for exploring the risk factors of persistent cough after uniportal video-assisted thoracoscopic pulmonary resection.

One hundred thirty-five patients with pulmonary nodules who underwent surgical treatment in the same surgical group from November 2019 to January 2020 were enrolled in this prospective study. The severity of cough and its impact on patients' quality of life before and after surgery were assessed by the Mandarin Chinese version of the Leicester cough questionnaire (LCQ-MC), and postoperative cough was tested by the cough visual analog scale (VAS) and cough symptom score (CSS). Risk factors of cough after pulmonary resection (CAP) were determined by univariate and multivariate logistic regression analysis.

The incidence of postoperative cough was 24.4% (33 of 135 patients). Univariate analysis showed that gender (female), the surgical site (upper right), the resection (lobectomy)was registered on ClinicalTrials.gov (NCT04204148).
Esophageal squamous cell carcinoma (ESCC) is among the leading causes of cancer mortality, especially in China. Advances in technology have resulted in significant clinical gains in the treatment of ESCC, with more precise radiotherapy now considered an integral part of standard patient care, either alone or in combination with chemotherapy. Though, a better understanding of tumoral radiosensitivity is still needed in order to develop strategies and further personalize radiation treatments.

We carried out whole-exome sequencing (WES) on paired tumors collected before and after radiotherapy from 11 patients with ESCC. A comprehensive analysis was performed to compare the somatic mutations, the driver genes mutations, the copy number variations (CNVs), the mutational signatures, the tumor's clonal composition, and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway between pre- and post-radiotherapy samples in this cohort.

According to the analysis of WES results, more insertion/deletion mutations (indels) were discovered in the post-radiotherapy samples than in the pre-radiotherapy samples (Wilcoxon rank-sum test, P=0.014). The mutation rate of driver gene Ephrin-A2 (
) was significantly reduced after radiotherapy (Fisher's exact test, P=0.035). However, comparison between the pre- and post-radiotherapy groups reveals no significant differences in other content.

Our study revealed the overall genomic profile of ESCC before and after radiotherapy and determined that a loss of
mutations might make cancer cells resistance to radiotherapy.

Surgery and stereotactic body radiotherapy (SBRT) are both suitable treatment options for early stage Non-small cell lung cancer (NSCLC), which accounts for the majority of lung cancer. This study compared the outcomes of sublobar resection (SLR) and SBRT in patients with stage T1-2N0M0 NSCLC with tumor size ≤5 cm.

Patients with T1-2N0M0 lung cancer who underwent SLR or SBRT between January, 2012 and December, 2016 were included in this retrospective study. The survival outcomes and toxicity of the SLR and SBRT cohorts were compared using Kaplan-Meier survival plots. In a second exploratory analysis, propensity score matching (PSM) was applied to reduce selection bias between the two groups of patients.

A total of 121 SLR and 109 SBRT cases were included. The average follow-up was 49.4 months. Prior to PSM, the 5-year overall survival (OS) and cancer-specific survival (CSS) rates in the SLR group (82.8% and 89.0%, respectively) were superior to those in the SBRT group (67.0% and 75.3%; P=0.001 and P=0.013, respectively). There were no statistically significant differences in the five-year locoregional control and disease-free survival (DFS) rates between the groups. PSM identified 40 patients from each treatment group who shared similar characteristics. At 5 years, the OS rates in the SLR and SBRT groups were comparable (79.9%
66.5%, respectively; P=0.154). After PSM, the rates of CSS, locoregional control, and DFS were also similar between the groups (P=0.458, 0.369, and 0.698, respectively).

Current practice guidelines recommend the following criteria for segmentectomy for non-small cell lung cancer (NSCLC) size ≤2 cm, margins ≥2 cm and no lymph node involvement. We sought to further stratify the selection criteria for segmentectomy for small peripheral high-grade tumors.

This retrospective database study was conducted using the Surveillance, Epidemiology and End Results (SEER) database. We queried for patients with high-grade (poorly differentiated/undifferentiated) pathological (p)T1a/b peripheral NSCLC (tumor size ≤2 cm), who underwent either lobectomy or segmentectomy between 2004 and 2015. Patients with node-positive disease or those who received any form of induction or adjuvant treatments were excluded.

A total of 4,332 patients met the inclusion criteria, with 3,977 patients (91.8%) treated with lobectomy and 355 patients (8.2%) who underwent segmentectomy. In a propensity matched pair analysis of 640 patients, lobectomy (n=320) showed significantly improved 5-year survival of 45.9%on for segmentectomy.
Lung cancer remains the leading cause of cancer deaths in the United States, and lung cancer screening has been shown to decrease this mortality. Adherence to lung cancer screening is paramount to realize the mortality benefit, and reported adherence rates vary widely. Few reports address non-adherence to screening, and our study sought to understand the non-compliant patients in our military population.

This Institutional Review Board approved retrospective review of patients enrolled in our screening program from 2013-2019 identified patients who failed to obtain a subsequent Low Dose CT scan (LDCT) within 15 months of their prior scan. Attempts were made to contact these patients and elucidate motivations for non-adherence via telephone.

Of the 242 patients enrolled, 183 (76%) patients were adherent to the protocol. Significant predictors of non-adherence versus adherence were younger age (P=0.008), female sex (P=0.005), and enlisted officer rank (P=0.03). There was no difference with regards to raceprogram. Compliance is critical to the efficacy of any screening modality, and adherence rates to lung cancer screening may be increased through improved contact with patients via multiple avenues (i.e., phone, email, and letter). There is benefit in contacting non-adherent patients as high rates of re-enrollment are possible.
Micropapillary-predominant adenocarcinoma (MPA) of the lung is associated with extensive lymph node involvement and rapid terminal metastasis. However, this subtype has been recognized for only a few years, and there have been few studies of the molecular mechanisms associated with its highly invasive behaviors.

The present study utilized immunohistochemical staining of surgically resected tissue blocks of MPA and lepidic-predominant lung adenocarcinoma to quantify the expression of specific biological markers in the WNT/β-catenin pathway and evaluate their influence on the lymph nodes invasion of these two types of lung adenocarcinomas.

Our findings revealed that disruption of the cell membrane cadherin-catenin complex, which weakens the tumor cell adherence of MPA, was caused by the dissociation of β-catenin from the cadherin-catenin complex and the subsequent accumulation of β-catenin in the cytoplasm. This caused abnormal activation of the WNT/β-catenin pathway. We also found that Wnt-1-specific overexpression and Axin1 inhibition in MPA could explain the redistribution and cytoplasmic retention of β-catenin.
