Article Synopsis
  • The study investigates the reliability of standardised uptake value (SUVmax) and other semi-quantitative parameters in assessing the staging of non-small-cell lung cancer (NSCLC) using PET/CT imaging.
  • It involved 319 patients diagnosed with NSCLC between 2014 and 2019, analyzing various factors like tumour size, SUVmax, metabolic tumour volume (MTV), and total lesion glycolysis (TLG) related to lymph node (LN) metastasis.
  • The researchers developed a new scoring system indicating that LNs scoring ≥3 significantly increased the risk of metastasis, suggesting these parameters can aid in improving cancer staging accuracy.

Background: It is difficult to select patients who will benefit from endobronchial treatment (ET) in malignant central airway obstruction (MCAO). We aimed to determine the tumor-related factors that affect the success of MCAO treatment.

Methods: ETs for MCAO between March 2019 and June 2021 were analyzed retrospectively.

Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) can be performed in a wide range, from minimal sedation to general anesthesia. Advanced age increases perioperative risks related to anesthesia and is also associated with many pathological processes that further increase morbidity and mortality. The ideal sedation protocol for EBUS-TBNA has yet to be determined in geriatric patients.

Article Synopsis
  • * Two patient groups were identified: one treated with chemoradiotherapy (G1) and the other with radical surgery (G2).
  • * Results showed that EBUS-TBNA was highly effective, with G1 showing a 50% malignant detection rate and G2 achieving perfect diagnostic values for sensitivity, specificity, and accuracy, suggesting it is a reliable rebiopsy method.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected millions of people worlwide and caused a pandemic that is still ongoing. The virus can cause a disease named as COVID-19, which is composed of multi systemic manifestations with a pulmonary system predominance. As the time passes, we are dealing more and more with a wide variety of effects and complications of the disease in survivors as far as with concerns about the clinical outcome and the timeline of symptoms in different patients.

Background: CoronaVac, an inactivated whole-virion SARS-CoV-2 vaccine, has been shown to be well tolerated with a good safety profile in individuals aged 18 years and older in phase 1/2 trials, and provided a good humoral response against SARS-CoV-2. We present the interim efficacy and safety results of a phase 3 clinical trial of CoronaVac in Turkey.

Methods: This was a double-blind, randomised, placebo-controlled phase 3 trial.

Aims: This study aimed to investigate the clinical and chest computed tomography (CT) features associated with clinical parameters for coronavirus disease (COVID-19) in the capital of Turkey, Ankara.

Materials And Methods: Epidemiological, clinical features, laboratory findings and radiological characteristics of 1563 hospitalised patients with COVID-19 in Ankara were collected, reviewed and analysed in this study. The risk factors associated with disease severity were investigated.

Background: Globally, coronavirus disease-2019 (COVID-19) is a new, highly contagious, and life-threatening virus. We aimed to demonstrate how we proceeded with bronchoscopic procedures without published guidelines at the inception of the pandemic period.

Materials And Methods: All bronchoscopic procedures applied from the first case seen in Turkey (11 March-15 May) were evaluated retrospectively.

COVID-19 pneumonia has high mortality rates. The symptoms are undiagnostic, the results of viral nucleic acid detection method (PCR) can delay, so that chest computerized tomography is often key diagnostic test in patients with possible COVID-19 pneumonia. In this review, we discussed the main radiological findings of this infection.

Introduction: Malignant central airway obstruction around the main carina often requires placement of Y‑shaped stents. In this study, we aimed to determine the safety of silicone Y stents placed around the main carina in the malignant airway obstruction by examining the long term complications, emergence times and treatment approaches of complications.

Materials And Methods: Between May 2012 and July 2015, 47 silicone Y stents were placed in 46 patients with malignant external compression or mixed type stenosis around the main carina.

Introduction: Recently, treatment of endobronchial hamartomas with interventional bronchoscopic methods has become possible. Although there are several reports of therapeutic benefits, the protocol of administration varies between centers and high recurrence rates continue to be a problem. In this study, we aimed to show that cryotherapy applied to the root of the bronchial wall after removal of the intraluminal portion of endobronchial hamartoma with interventional bronchoscopic methods can prevent recurrences.

Objective: Convex probe endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) is a minimally invasive technique with high sensitivity in the mediastinal staging of non-small cell carcinoma (NSCLC). In recent years, molecular testing has been developed to study genetic mutations in NSCLC. There are studies revealing improved survival in advanced NSCLC using targeted therapy as the first-line treatment in these patients.

Background/aim: This study aimed to analyze EGFR, KRAS, and BRAF mutations in females with micropapillary predominant invasive lung adenocarcinoma and their relationships with immunohistochemical and clinicopathological patterns.Materials and methods: A total of 15 females with micropapillary lung adenocarcinoma were selected. Mutational analysis of the EGFR, KRAS, and BRAF genes was carried out.

Relapsing polychondritis (RP) is a rare autoimmune disease, characterized by episodic inflammatory attacks on cartilaginous tissue. Elastic cartilage of the ears and nose, hyaline cartilage of the peripheral joints, vertebral fibrocartilage, tracheobronchial cartilage, and tissues rich in proteoglycan such as those in the eyes, heart, blood vessels, and inner ear are more likely to be affected. A 35-year-old male presented with complaints of hoarseness, tinnitus and dyspnea for 19 years, with a history of several diagnostic and therapeutic interventions for laryngeal and respiratory tract.

Background: The development of central airway obstruction during malignant diseases is an important cause of morbidity and mortality. Endobronchial therapies can decrease the patient's symptoms and improve quality of life. Here, we compare airway recanalization methods: argon plasma coagulation with mechanical tumor resection (APC + MTR) and cryorecanalization (CR efficiency, complications, restenosis rate, and time to restenosis) in patients with malignant exophytic endobronchial airway obstruction.

An ectopic thyroid gland results from the abnormal migration of the thyroid in the course of its development. Primary ectopic mediastinal thyroid is very rare and occurs in less than 1% of all goiters that can be surgically excised. Ectopic thyroid tissue has a characteristic sonographic appearance as smooth-bordered, homogeneous, hypoechoic tissue with fine specular echoes.

Background: Small cell lung cancer (SCLC) commonly presents as hilar/mediastinal masses. In some occasions, conventional flexible bronchoscopy fails and a substantial amount of time is lost until establishing the diagnosis.

Objective: The aim of the study was to demonstrate the superiority of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) compared to conventional methods in establishing the diagnosis as an initial modality as well as to point out the saved time until the diagnosis.

Lung metastases from extrapulmonary malignancies are common however endobronchial metastases (EBM) from nonpulmonary neoplasms are rare. A variety of extrathoracic tumors have a tendency to EBM especially breast, colon, and renal carcinomas are most frequent reported tumors however EBM of germ cell tumors are extremely rare. A 39-year-old and a 27-year-old male patient were admitted to our hospital with hemoptysis and dyspnea at different times.

Background: Cryobiopsy, which provides larger specimens without crush artifact, is a good option for the diagnosis of visible endobronchial tumors. While there are several papers on diagnostic performance, application protocols vary between centers. In this study, we aimed to find the optimal number of cryobiopsies in endobronchial tumors.
