Multi-omics Analysis Reveals Molecular Changes During Early Progression of Precancerous Lesions to Lung Adenocarcinoma in Never-Smokers.

Lung cancer is the most common cause of cancer mortality globally, and the prevalence of lung adenocarcinoma (LUAD), the most common lung cancer subtype, has increased sharply in East Asia. Early diagnosis leads to better survival rates, but this requires an improved understanding of the molecular changes during early tumorigenesis, particularly in non-smokers. Here, we performed whole exome-sequencing and RNA-sequencing of samples from 94 East Asian patients with precancerous lesions (25 with atypical adenomatous hyperplasia [AAH]; 69 with adenocarcinoma in situ [AIS]) and 73 patients with early invasive lesions (minimally invasive adenocarcinoma [MIA]).

Outcome and survival analysis of pulmonary metastasectomy for primary sarcoma with pulmonary metastases.

Background: Sarcomas are rare malignancies, accounting for approximately 1% of all cancers. Pulmonary metastases are the most preferential site for distant metastasis in malignant soft tissue sarcomas. Despite the lack of evidence from large randomized trials to support treatment guidelines, surgical resection of resectable metastatic tumors remains the current standard of care.

Comparative Analyses of the Outcomes Between Lobectomies and Trisegmentectomies/Lingulectomies in the Surgical Management of Clinical Stage I Left Upper Lobe Non-small Cell Lung Cancer.

Background: Lobectomies are the standard surgical intervention for lung cancer; however, recently, surgeons have considered segmentectomies for smaller tumors, with their potential for favorable survival outcomes while preserving lung function. The surgical outcomes of trisegmentectomies/lingulectomies and lobectomies for clinical stage I left upper lobe (LUL) non-small cell lung cancers (NSCLCs) remain undetermined. Thus, our study aimed to assess the differences between the short-term surgical and long-term survival outcomes in patients with clinical stage I LUL NSCLC who underwent trisegmentectomies/lingulectomies and those who underwent lobectomies.

The SARS-unique domain (SUD) of SARS-CoV-2 nsp3 protein inhibits the antiviral immune responses through the NF-κB pathway.

Nuclear factor κB (NF-κB) plays a crucial role in various cellular processes, including inflammatory and immune responses. Its activation is tightly regulated by the IKK (IκB kinase) complex. Upon severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, the virus is initially recognized by the innate immune system and typically activates the NF-κB pathway, leading to a severe inflammatory response.

Plasma Cytokines Pattern as a Prognostic Marker for Esophageal Squamous Cell Carcinoma via Unsupervised Clustering Analyses.

Introduction: Cytokines such as tumor necrosis factor-alpha (TNF-α), interleukin 6 (IL6), interferon-gamma (IFN-γ), interleukin 17-alpha (IL17-α), and interleukin 33 (IL33) play critical roles in immune responses and may impact cancer prognosis in future. However, few studies have simultaneously explored the prognostic impact of these cytokines for cancer. In this study, we aim to apply the unsupervised clustering analysis to approach the correlation between the expression of these cytokines and the subsequent prognosis of patients with esophageal squamous cell carcinoma (ESCC).

Outcome and Survival Analysis of Multicenter Lung Metastasectomy for Primary Liver Tumor with Pulmonary Metastasis.

Oligopulmonary metastases from primary liver tumors are typically treated surgically. We evaluated the clinical outcomes after lung metastasectomy in patients with pulmonary metastases from primary liver tumors. We retrospectively enrolled 147 consecutive patients with lung metastases from liver cancer who had undergone pulmonary metastasectomies at three medical centers between February 2007 and December 2020.

Evaluating postoperative recovery in uniportal versus needlescopic video-assisted thoracoscopic surgery for primary spontaneous pneumothorax: a comparable study.

Objectives: Primary spontaneous pneumothorax (PSP) is a common disease in young and thin male. Operation has been regarded as definitive treatment for it. However, the operative methods for those patients are under dispute.

Prognostication and optimal criteria of circumferential margin involvement for esophageal cancer after chemoradiation and esophagectomy.

Purpose: Circumferential radial margin (CRM) involvement by tumor after resection for esophageal cancer has been suggested as a significant prognostic factor. However, the prognostic value of CRM involvement after surgery with neoadjuvant concurrent chemoradiotherapy (CCRT) is unclear. This study aimed to evaluate the prognostic value of and survival outcomes in CRM involvement as defined by the Royal College of Pathologists (RCP) and the College of American Pathologists (CAP) for patients with esophageal cancer undergoing neoadjuvant CCRT and esophagectomy.

Stripping Massage and Literature Review in Post-Thoracoscopic Chest Pain Management.

The aim of this randomized study was to investigate whether stripping massage (SM) of myofascial trigger points in the lower rhomboid muscle could alleviate chest pain in patients following thoracoscopic surgery. In addition, a literature review was conducted to assess the effectiveness of various pain management techniques. Sixty adult patients who reported a visual analog scale (VAS) score of 4 or higher were randomly assigned to receive conventional analgesics alone (conventional group) or combined with SM twice daily for 2 weeks (SM group).

Selection of minimally invasive surgical approaches for treating esophageal cancer.

Minimally invasive esophagectomy has gradually been accepted as an active treatment option for surgery of esophageal cancer. However, there is no consensus about how to perform the procedures in the thoracic and abdominal phase including anastomosis in the neck (McKeown) or chest (Ivor Lewis), VATS, robotic-assisted or reduced port approaches or various endoscopic abrasion techniques. Further studies to investigate the roles of these novel techniques are required to treat the various patient populations.

The management of postoperative upper alimentary tract fistulas: A single-center experience of endoscopic tissue glue repair and recommendations of a systematic review.

Background/purpose: The appropriate management of postoperative upper alimentary tract fistula (UATF) remains uncertain. The efficacy of esophagogastroduodenoscopy (EGD) tissue glue repair in the treatment of patients with postoperative UATF was explored. We also conducted a systematic review of the literature regarding the inpatient management of UATF.

Tracheal reconstruction with nail grafts: A novel approach.

Background: The replacement of tracheal defects has been a challenge for investigators worldwide. We aimed to develop autologous nail grafts for the reconstruction of anterior tracheal defects.

Methods: Toenail grafts were implanted to improve the structural integrity of the trachea in patients with tracheal diseases.

Drainless Thoracoscopic Lobectomy for Lung Cancer.

Objectives: Drainless video-assisted thoracoscopic (VATS) wedge resection has been demonstrated as feasible in treating various lung diseases. However, it remains unknown whether this surgical technique can be effectively applied to lobectomy. In the current study, we evaluated the perioperative outcome of drainless, minimally invasive lobectomy in patients with lung cancer.

The Long-Term Clinical Impact of Thoracic Endovascular Aortic Repair (TEVAR) for Advanced Esophageal Cancer Invading Aorta.

Background: Advanced esophageal cancer invading the aorta is considered unsuitable for surgery with definitive chemotherapy or chemoradiation as the treatments of choice. In the current study, we evaluated the long-term clinical impact of combining thoracic endovascular aortic repair (TEVAR) with multimodality treatment in caring for such patients.

Methods: We evaluated 48 patients who had advanced esophageal cancer with aortic invasion.

Comparison of perioperative outcomes between intubated and nonintubated thoracoscopic surgery in children.

Background/purpose: This study aimed to compare our experiences of nonintubated video-assisted thoracoscopic surgery (VATS) for pneumothorax and lung tumor resections with that of intubated VATS in pediatric patients.

Methods: In total, 17 nonintubated and 64 intubated pediatric VATS were performed between January 2012 and December 2018. Patient characteristics, operation period, comorbidities, precedent lung surgery, diagnosis, type of anesthesia, side and type of procedure, and perioperative outcomes were collected from medical records.
