AI Article Synopsis
- The study aimed to assess the incidence of lymph node metastasis and the effects of systematic lymph node dissection (LND) in patients with thymomas, a type of tumor affecting the thymus gland.
- Out of 54 patients undergoing LND from 2017 to 2020, there was a significant increase in the number of lymph nodes retrieved compared to a control group that had surgery from 2015 to 2017.
- While more nodal metastases were detected in the study group, the overall occurrence was low, suggesting that LND may not be necessary in cases of small, encapsulated, and low-grade thymomas due to risks of complications.
Article Abstract
Objectives: Lymph node dissection (LND) and nodal metastases in thymomas remain controversial and understudied. The aim of our study was to evaluate the incidence of nodal metastasis and the short term outcomes of systematic LND in thymomas.
Material And Methods: From December 2017 to September 2020, we performed 54 LND conducted according to the International Thymic Malignancy Interest Group (ITMIG) lymph node map. This group was compared to a historical control group of 55 patients who underwent surgery in our center from January 2015 to November 2017.
Results: LND was performed in 72 % and in 5 % of the cases in the study cohort group and historical control group, respectively. The number of lymph nodes retrieved was significantly higher in the study cohort group (3.89 per patient vs. 1.62, p = 0.0021). In the whole population studied, nodal metastases were found in 3 patients (2.8 % of all patients) with 5.6 % in the cohort study group vs. 0 % in the control group (p = 0.12). Patients with nodal metastasis had larger tumors (> 7 cm), and a higher histology grade (B2 and B3). There was a trend towards higher risk of laryngeal nerve palsy in the cohort study group (9.3 % vs. 1.8 %, p = 0.11).
Conclusion: Systematic LND increases the number of lymph node harvested and detects more lymph node metastases, which remains infrequent in thymomas. The impact of LND and the true prognostic significance of lymph node metastases remains controversial. Given the potential complications, LND or sampling should not be perfomed in small, encapsulated and low grade thymomas.

Introduction: The core objective of this study was to precisely locate metastatic lymph nodes, identify potential areas in nasopharyngeal carcinoma patients that may not require radiotherapy, and propose a hypothesis for reduced target volume radiotherapy on the basis of these findings. Ultimately, we reassessed the differences in dosimetry of organs at risk (OARs) between reduced target volume (reduced CTV2) radiotherapy and standard radiotherapy.

Introduction: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is commonly used for diagnosing mediastinal lymphadenopathy. Despite a low complication rate, severe hemorrhage can occur which is reported in this literature, particularly in hypervascular conditions like Castleman disease.
Methods: A 54-year-old male with idiopathic multicentric Castleman disease underwent EBUS-TBNA for mediastinal lymph node sampling.

Background: Mycobacterium avium complex (MAC) is a common pathogen causing non-tuberculous mycobacterial infections, primarily affecting the lungs. Disseminated MAC disease occurs mainly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, hematological malignancies, or those positive for anti-interferon-γ antibodies. However, its occurrence in solid organ transplant recipients is uncommon.

Background: This study aimed to explore the relationship of cervical tumor lesion location (CTLL) with bilateral parametrial involvement (PI) and pelvic lymph node metastasis (LNM).
Methods: The study retrospectively analyzed the clinicopathologic and imaging data of patients with cervical squamous cell carcinoma (SCC) retrieved from multiple centers. According to the CTLL, patients were allocated to three groups: a middle one third group, a unilaterally dominant group, and the entire-region group.
