AI Article Synopsis
- The study evaluates the accuracy of EBUS-TBNA combined with EUS-FNA or EUS-B-FNA in staging non-small cell lung cancer, stressing the need for mediastinoscopy validation when results are negative despite imaging indications.
- A retrospective analysis of 47 patients revealed that 12.8% were upstaged to N2 after surgery, with station 7 being the most frequently involved, highlighting the limitations of current imaging techniques.
- The findings suggest that upstaging was unaffected by various factors analyzed, and only two patients with negative EBUS/EUS results were considered for mediastinoscopy, indicating a need for improved noninvasive diagnostic methods.
Article Abstract
Objective: Although EBUS-TBNA combined with EUS-FNA or EUS-B-FNA stands as the primary approach for mediastinal staging in lung cancer, guidelines recommend mediastinoscopy confirmation if a lymph node identified on chest CT or showing increased PET scan uptake yields negativity on these techniques. This study aimed to assess the staging precision of EBUS/EUS.
Methods: We conducted a retrospective study comparing the clinical staging of non-small cell lung cancer patients undergoing EBUS/EUS with their post-surgery pathological staging. We analyzed the influence of histology, location, tumor size, and the time lapse between EBUS and surgery. Patients with N0/N1 staging on EBUS/EUS, undergoing surgery, and with at least one station approached in both procedures were selected. Post-surgery, patients were categorized into N0/N1 and N2 groups.
Results: Among the included patients (n = 47), pathological upstaging to N2 occurred in 6 (12.8%). Of these, 4 (66.7%) had a single N2 station, and 2 (33.3%) had multiple N2 stations. The adenopathy most frequently associated with upstaging was station 7. None of the analyzed variables demonstrated a statistically significant difference in the occurrence of upstaging. PET scan indicated increased uptake in only one of these adenopathies, and only one was visualized on chest CT.
Conclusions: Upstaging proved independent of the studied variables, and only 2 patients with negative EBUS/EUS would warrant referral for mediastinoscopy. Exploring other noninvasive methods with even greater sensitivity for detecting micrometastatic lymph node disease is crucial.

Pulmonary embolism (PE), a form of venous thromboembolism, is a frequently observed complication in malignancies, with a notably high incidence in individuals with lung cancer. The presence of PE markedly reduces the quality of life and has a significant impact on the prognosis of those diagnosed with both lung cancer and PE. As a result, timely diagnosis and intervention are of paramount importance.

Objective: Rapid on-site evaluation (ROSE) of respiratory cytology specimens is a critical technique for accurate and timely diagnosis of lung cancer. However, in China, limited familiarity with the Diff-Quik staining method and a shortage of trained cytopathologists hamper utilization of ROSE. Therefore, developing an improved deep learning model to assist clinicians in promptly and accurately evaluating Diff-Quik stained cytology samples during ROSE has important clinical value.

Background: To date, there remains a paucity of comparative investigations pertaining to preoperative immunochemotherapy and conventional chemotherapy in the context of limited-stage small-cell lung cancer (LS-SCLC) patients. This study conducted a comprehensive comparative assessment concerning the safety and efficacy profiles of preoperative immunochemotherapy and chemotherapy in individuals diagnosed with stage I-IIIB SCLC.
Methods: This investigation collected 53 consecutive patients diagnosed with LS-SCLC spanning stage I to IIIB who underwent preoperative immunochemotherapy or conventional chemotherapy at our hospital from January 2019 to July 2021.

Background: There is a need to expand eligibility criteria for lung cancer screening beyond age and smoking history. In this study, we sought to assess whether light-or-never-smokers and heavy smokers differ in molecular and immunologic markers based on conventional lung cancer screening criteria.
Methods: We conducted a retrospective review of lung cancer cases from 2005 to 2018 at a tertiary Canadian institution.
