bronchiectasis.
Treatment with bronchodilators such as LAMA or LABA was effective in improving lung function in patients with bronchiectasis, regardless of concurrent treatments that also improve lung function. These data may support the use of LAMA and LABA in patients with bronchiectasis.
Esophageal cancer surgery has historically been associated with high levels of postoperative morbidity and mortality. Post-esophagectomy diaphragmatic hernia (PEDH) represents a potentially life-threatening surgical complication, with incidence and risk factors not clearly demonstrated. This study evaluates presenting characteristics and repair outcomes in PEDH after Ivor Lewis esophagectomy for cancer.

All consecutive patients who underwent esophageal cancer surgery between March 1997 and April 2018 at two high-volume centers were included. The patients underwent Ivor Lewis esophagectomy and were managed according to a standardized follow-up care plan. The primary outcomes included PEDH incidence, risk factor identification, and surgical results after hernia repair. Patient characteristics and perioperative data were collected and a multivariate analysis was performed to identify risk factors for PEDH.

A total of 414 patients were enrolled and 22 (5.3%) were diagnosed with PEDH during a median follow-u requiring surgical repair. Pathological complete response and lymph node harvest were found to be independent risk factors for PEDH, independently of the esophagectomy technique.

The decision for administering adjuvant chemotherapy (AC) in completely resected node-negative non-small cell lung cancer (NSCLC) is guided by likelihood of disease recurrence or death based on tumor, node, metastasis (TNM) stage. However, within each TNM stage are sub-groups of patients that are more or less likely to relapse than stage alone predicts.

In this retrospective cohort study, prospective data from 394 consecutive patients who underwent complete resection of node-negative NSCLC without adjuvant therapies, between 2002 and 2019 was retrospectively analyzed. Independent tumor and host risk factors for recurrence were subjected to multivariate analysis to develop a predictive risk model distributing patients into low-risk or high-risk categories.

Recurrence risk was independently predicted by a neutrophillymphocyte ratio (NLR) of ≥3.5 [hazard ratio (HR), 1.9; 95% confidence interval (CI), 1.1-3.5], visceral pleural invasion (HR, 2.2; 95% CI, 1.3-3.8), histopathology other than adenocarcinoma or squamous cell (HR, 2.6; 95% CI, 1.2-5.5) and tumor size >33 mm (HR, 3.9; 95% CI, 2.3-6.7). The specific combination of risk factors contributed to a score for a risk model which classified 9% of Stage I and 69% of Stage ≥II patients as high-risk. The predicted 5-year disease-free survival (DFS) for high-risk and low-risk patients as scored by the predictive model was 30% and 85%, respectively.

Our readily reproducible, low-technology model, developed from individually validated tumor/host risk factors, identified sub-groups of resected node-negative NSCLC patients at significantly discordant risk of recurrence to their TNM stage category.

Complete tumor removal via esophagectomy or endoscopic excision has been associated with the greatest survival in early-stage esophageal cancer. However, patient health, anatomy, or goals of care may render patients ineligible for excision or resection. In this setting, chemoradiation (CRT) may be considered as a nonsurgical approach, however the outcomes associated with CRT in early-stage esophageal cancer are incompletely understood.

The National Cancer Database was queried for treatment-naïve cT1/T2, N0, M0 esophageal cancer patients managed with concurrent multi-agent CRT (≥50 Gy) between 2004 and 2015. https://www.selleckchem.com/products/CP-690550.html Medically inoperable patients were excluded. Kaplan-Meier curves were generated to estimate 5-year overall survival (OS) from diagnosis in both stages.

Of the 828 patients identified, 279 were cT1 and 549 were cT2. For cases after 2010, cT1 (N=124) was further stratified in cT1a (N=32, 25.8%) and cT1b (N=46, 37.1%). Kaplan-Meier estimates demonstrated a 5-year survival of 21.7% for cT1 and 25.9% for cT2. Sensitivity analyses were performed to mitigate competing survival risk from poor health. Among 589 comorbidity-free patients (i.e., Charlson = score zero), the 5-year survival with CRT was 23.4% for cT1 and 27.8% for cT2. Finally, a subset of patients who refused a recommended surgery were evaluated with 5-year survival cT1 =33.5% and cT2 =33.4%).

Up to a third of selected patients with early-stage esophageal cancer may be cured after CRT as definitive non-surgical treatment. However, cure rates may be underestimated in this setting, secondary to persistent health-related bias.

Esophagectomy via transcervical incision inflatable single-port mediastinoscope combined with laparoscopy as a safe and feasible minimally invasive technique has gained attention recently. But the occurrence of Intraoperative events is inevitable. It's necessary to investigate and discuss the intraoperative events and countermeasures during operation.

Intraoperative events were retrospectively reviewed in 60 patients who underwent esophagectomy via transcervical incision inflatable single-port mediastinoscope combined with laparoscopy in the recent 3 years.

There was no perioperative death and no aortic or bronchial injury. Bronchial artery injury occurred in 2 cases (3.34%), bronchial artery combined with azygos vein hemorrhage occurred in 1 case (1.67%). The pleura were injured in 3 cases (5%). Recurrent laryngeal nerve injury was noticed in 7 cases (11.67%). Thoracic duct injury occurred in 1 case (1.67%).

As a new surgical method, esophagectomy via transcervical incision inflatable single-port mediastinoscope combined with laparoscopy is considered safe and feasible, but requires improvement when compared with traditional surgical methods.
