AI Article Synopsis
- - Cervical cancer is a significant health issue in Ethiopia, often leading to advanced disease when diagnosed, with ureteral involvement being common, necessitating stent placement to manage obstruction.
- - A study reviewed data from 175 patients who underwent ureteral stenting, finding an overall success rate of only 54.2%, with lower success in those needing therapeutic stenting compared to prophylactic.
- - Key factors predicting stent failure included bilateral hydronephrosis and elevated serum creatinine levels, suggesting that alternatives like percutaneous nephrostomy might be more effective for these patients.
Article Abstract
Objective: Cervical cancer is the leading gynecologic malignancy in Ethiopia. The diagnosis is often delayed and many patients present with locally advanced disease. Involvement of the ureters with or without the development of hydroureteronephrosis is a common finding. Ureteral stent placement is a modality utilized to relieve an established obstruction (therapeutic) or to prevent its early occurrence (prophylactic). However, the procedure may not be successful in all patients. The objective of this study is to assess the factors associated with low success rate of ureteral stenting in these patients with locally advanced disease.
Methods: This is a hospital based cross-sectional study of patients diagnosed with locally advanced cervical cancer for whom a retrograde ureteral stent placement is attempted from January 2019 to March 2020. Data of 175 patients were retrieved by a retrospective chart review and analyzed for factors associated with low procedural success.
Results: Socio-demographic data were similar between patients regardless of procedural success. The overall success rate of stenting was 54.2 %. In the prophylactic group (with no hydronephrosis and normal creatinine) success rate was 94 % and in the therapeutic group 42.6 %. Logistic regression analysis showed that bilateral hydronephrosis and increased serum creatinine were indicators of significant ureteral obstruction and were predictors of stent placement failure.
Conclusion: Increased serum creatinine and presence of hydronephrosis are risk factors for failed ureteral stenting. For these patients, other options of urinary diversion such as percutaneous nephrostomy should be considered from the outset.

Merkel cell carcinoma (MCC) is a rare skin cancer that mainly affects the elderly, and whose incidence is increasing. Although the exact origin of this cancer remains uncertain, research in recent years has revealed that MCC develops through two oncogenesis pathways: virally induced by the Merkel polyomavirus (80% of cases) and induced by mutations linked to ultraviolet rays (20% of cases). MCC is an aggressive cancer, with a high mortality rate and limited therapeutic options in advanced stage.

Brain tumors are classified as rare diseases, with an annual occurrence of 300,000 cases and account for an annual loss of 241,000 lives, highlighting their devastating nature. Recent advancements in diagnosis and treatment have significantly improved the management and care of brain tumors. This chapter provides an overview of the common types of primary brain tumors affecting language functions-gliomas and meningiomas.

Purpose/objective(s): Use of intensity-modulated radiation therapy (IMRT) versus three-dimensional conformal external beam radiation therapy (3D-CRT) for definitive chemoradiation therapy (CRT) in locally advanced non-small cell lung cancer (LA-NSCLC) has been associated with decreased late pneumonitis, decreased high dose to the heart (itself associated with improved overall survival), and improved patient quality of life. In a statewide radiation oncology quality consortium, we sought to evaluate the impact of IMRT versus 3D-CRT treatment technique on dosimetry and toxicity.
Materials/methods: From 2012 to 2022, 1746 LA-NSCLC patients meeting inclusion criteria underwent definitive RT (90% CRT) with either 3D-CRT (n=313) or IMRT (n=1433) and were enrolled in the [quality consortium] prospective, multicenter statewide initiative.

Based on the concept of continuous dopaminergic stimulation (CDS), Rotigotine Behenate extended-release microspheres for injection (RBEM) are currently under development. To support human clinical trials of RBEM, a 20-week repeat-dose toxicity study was conducted. SD rats intramuscularly received RBEM (60, 180, and 540 mg/kg) once every 4 weeks for 5 repeated doses followed by a 12-week recovery period, no clear sex difference was noted in the plasma exposure of rotigotine in rats, and the exposure generally increased in a dose-proportional manner.
