Summary
Bladder cancer primarily affects older adults with poor outcomes. This study explores targeted therapies for cisplatin-ineligible patients, analyzing genomic alterations for new treatment strategies.
Area of Science:
- Oncology
- Genetics
- Geriatric Medicine
Background:
- Bladder cancer predominantly affects elderly patients with comorbidities.
- Cisplatin chemotherapy is standard but has poor outcomes and limited eligibility.
- Genomic sequencing reveals actionable alterations in high-grade urothelial carcinoma.
Purpose of the Study:
- To investigate targeted therapy potential in bladder cancer.
- To address treatment limitations in cisplatin-ineligible patients, particularly older adults.
- To confirm if genomic alterations represent true oncogenic vulnerabilities.
Main Methods:
- Analysis of comprehensive genome sequencing data from high-grade urothelial carcinoma.
- Evaluation of demographic and genetic factors in bladder cancer patients.
- Proposal for bladder cancer as a model for targeted therapy research.
Main Results:
- High prevalence of potentially actionable genomic alterations identified.
- Confirmation of genomic events as oncogenic vulnerabilities is pending.
- Limited treatment options exist for cisplatin-ineligible bladder cancer patients.
Conclusions:
- Bladder cancer presents an ideal model for studying targeted therapies.
- Targeted therapies offer a promising avenue for older patients ineligible for cisplatin.
- Novel treatment strategies are critically needed for this patient population.

01:21Nursing Assessment of the Genitourinary System I: Health History
813
The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1. Gathering Patient InformationA complete health history includes the patient’s personal,...

01:23Urinary Bladder
4.7K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

3.6K
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
857
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

827
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

01:20The Retinoblastoma Gene
3.7K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
