Objective: To analyze the retroperitoneal lymph node metastasis in epithelial cancer of the ovary and offer scientific indications for lymph node radical dissection.
Methods: Fifty-eight patients with ovarian cancer treated from January 1990 to December 2000 were retrospectively reviewed. Single-factor and multifactor analysis with Logistic regression model were performed by SPSS 10.0 statistic software.
Results: The metastasis rates of overall lymph nodes, pelvic nodes and para-aortic nodes were 48.3%, 37.9% and 25.9% respectively, among which no significant difference was noted (P > 0.05). Single-factor analysis showed that tumor location, ascitic condition, clinical stage and the size of residual tumor were associated with retroperitoneal lymph node metastasis. Multifactor analysis revealed that clinical stage and size of residual tumor were independent risk factors for metastasis of retroperitoneal lymph nodes.
Conclusion: For early ovarian cancer patients, it is extremely important to perform radical dissection of the retroperitoneal lymph nodes. For advanced or residual lesions, radical dissection of pelvic nodes and para-aortic nodes could be considered in the second exploration.

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.
