Testicular cancer is the most common malignancy in young men with seminomas comprising almost half of all germ cell tumours. Benign ganglioneuromas are rare tumours derived from the sympathetic nervous system. They usually occur in aldolescents and young adults and are predominantly located in the mediastinum and retroperitoneum. We report a case of a patient with synchronous metastatic testicular seminoma with retroperitoneal lymph node involvement and a benign retroperitoneal ganglioneuroma (RGN) which caused diagnostic and management challenges. The patient had a complete response following combination chemotherapy for his seminoma and subsequently underwent complete resection of his ganglioneuroma.

Introduction: Immune checkpoint inhibitors (ICIs) have revolutionized cancer therapy by enhancing the antitumor immune response. This case describes an 80-year-old male with synchronous multiple primary malignancies (MPMs), including lung metastatic hepatocellular carcinoma (HCC), and non-small cell lung carcinoma (NSCLC), and brain metastatic urothelial carcinoma, who was treated with dual ICI therapy.

Case Presentation: The patient, with a history of diabetes, hypertension, dyslipidaemia, well-differentiated neuroendocrine duodenal tumors and micronodular exogenous cirrhosis (Child-Pugh class A), presented with a non-invasive bladder carcinoma (pT1N0M0) resected endoscopically in December 2022.

Traditional Chinese Medicine Nursing for Gastrointestinal Function Recovery in Patients with Uterine Fibroids After High-Intensity Focused Ultrasound Treatment.

J Multidiscip Healthc

December 2024

Department of Nursing, Shanghai Key Laboratory of Maternal Fetal Medicine, Shanghai Institute of Maternal-Fetal Medicine and Gynecologic Oncology, Shanghai First Maternity and Infant Hospital, School of Medicine, Tongji University, Shanghai, 200092, People's Republic of China.

Objective: To investigate the effect of traditional Chinese medicine nursing scheme on gastrointestinal function recovery in patients with uterine fibroids after high-intensity focused ultrasound treatment.

Methods: By convenient sampling method, 110 patients who received high-intensity focused ultrasound treatment for uterine fibroids from January 2023 to December 2023 in HIFU Treatment Center, a Grade-III obstetrics and gynecology hospital in Shanghai were selected as the study objects and were divided into a control group (n = 54) and experimental group (n = 56) by non-synchronous control study. The control group was treated with conventional nursing mode, and the experimental group was treated with traditional Chinese medicine nursing plan for gastrointestinal function recovery of patients with uterine fibroids after sea aid treatment.

Objectives: To investigate the association between venous tumor thrombus (VTT) and the risk of pulmonary metastases in patients with clear cell renal cell carcinoma (ccRCC).

Methods: We queried our institutional registry for ccRCC patients undergoing radical nephrectomy (1970-2019). Cox proportional hazards regression models, adjusting for factors associated with ccRCC progression, were used to determine whether VTT was associated with pulmonary metastases.

This study aimed to investigate the correlation between baseline MRI features and baseline carcinoembryonic antigen (CEA) expression status in rectal cancer patients. A training cohort of 168 rectal cancer patients from Center 1 and an external validation cohort of 75 rectal cancer patients from Center 2 were collected. A nomogram was constructed based on the training cohort and validated using the external validation cohort to predict high baseline CEA expression in rectal cancer patients.
