Summary
Urologists are nearly 5 times more likely to prescribe enzalutamide over abiraterone for advanced prostate cancer. Understanding these prescribing differences between urologists and medical oncologists is crucial for patient care.
Area of Science:
- Oncology
- Urology
- Pharmacology
Background:
- Oral therapies enable continued patient care for advanced prostate cancer with castration resistance.
- Prescribing patterns for these advanced prostate cancer oral therapies vary between specialties.
Purpose of the Study:
- To compare the prescribing practices of urologists and medical oncologists for oral advanced prostate cancer therapies.
- To identify factors influencing prescribing preferences between enzalutamide and abiraterone.
Main Methods:
- Utilized Medicare Part D Prescribers data (2013-2019).
- Classified physicians as enzalutamide or abiraterone prescribers based on prescription volume.
- Employed generalized linear regression to analyze prescribing determinants.
Main Results:
- In 2019, urologists were significantly more likely to prescribe enzalutamide (OR 4.91).
- Urologists were more likely to prescribe generic abiraterone (37.9%) compared to medical oncologists (62.5%).
Conclusions:
- Significant prescribing differences exist between urologists and medical oncologists in advanced prostate cancer treatment.
- Further understanding of these disparities is essential for healthcare.
- These findings highlight potential variations in treatment selection and generic drug utilization.

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
