After surgical castration triptorelin does not induce any further decrease in serum testosterone levels
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
After surgical castration, the testicles are removed, resulting in a significant decrease in testosterone production. Triptorelin is a medication that works by suppressing the production of testosterone in the body. Since surgical castration already eliminates testosterone production, triptorelin would not have any further effect on reducing serum testosterone levels. Therefore, the statement that triptorelin does not induce any further decrease in serum testosterone levels after surgical castration is true.Rate this question:

Risk Factors of prostate cancer all are true except:
- A.
More common before 40 years old
- B.
More common after 50 years old
- C.
Higher risk for African American
- D.
More common in north America and north western Europe
Correct Answer
A. More common before 40 years oldExplanation
Prostate cancer is generally more common in older individuals, with the risk increasing as age advances. This is because prostate cells tend to undergo changes over time, making them more susceptible to cancer development. Therefore, it is less common for prostate cancer to occur before the age of 40.Rate this question:

Prostate cancer initial detection signs all are true except
- A.
Acute urine retention.
- B.
Lower right quadrant abdominal pain.
- C.
Nodule on digital rectal examination.
- D.
Elevated PSA levels
Correct Answer
B. Lower right quadrant abdominal pain.Explanation
Lower right quadrant abdominal pain is not a typical initial detection sign of prostate cancer. Prostate cancer is a condition that primarily affects the prostate gland, which is located in the pelvis, not the lower right quadrant of the abdomen. Therefore, this symptom is not associated with prostate cancer and is not considered a reliable indicator for its initial detection. On the other hand, acute urine retention, nodule on digital rectal examination, and elevated PSA levels are all potential signs that can be observed in the early stages of prostate cancer.Rate this question:

The most common test used for Prostate cancer diagnosis is:
- A.
MRI
- B.
CAT scan
- C.
DRE and PSA test
- D.
Ultrasound
Correct Answer
C. DRE and PSA testExplanation
The most common test used for Prostate cancer diagnosis is DRE (Digital Rectal Exam) and PSA (Prostate-Specific Antigen) test. DRE involves a doctor manually examining the prostate gland through the rectum to check for any abnormalities. PSA test measures the levels of PSA, a protein produced by the prostate gland, in the blood. Elevated PSA levels can indicate the presence of prostate cancer. These tests are commonly used together as they provide valuable information for diagnosing prostate cancer and determining the need for further investigations or treatment.Rate this question:

The Grading system followed for prostate cancer histological evaluation is:
- A.
Glasco Grading system
- B.
TNM Grading System
- C.
RECIST Grading System
- D.
Gleason Grading system
Correct Answer
D. Gleason Grading systemExplanation
The Gleason Grading system is used for histological evaluation of prostate cancer. It is a method of grading the tumor based on its microscopic appearance. The system assigns a score ranging from 2 to 10, with higher scores indicating a more aggressive and poorly differentiated tumor. The Gleason score is determined by evaluating the two most prevalent patterns observed in the tumor sample. This grading system helps in predicting the prognosis and guiding treatment decisions for prostate cancer patients.Rate this question:

RTOG and EORTC data indicate that there is an advantage to start immediately after diagnosis hormonal treatment for cancer of prostate with metastases
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The explanation for the given correct answer is that both RTOG (Radiation Therapy Oncology Group) and EORTC (European Organisation for Research and Treatment of Cancer) have provided data that shows starting hormonal treatment immediately after diagnosis for prostate cancer with metastases has an advantage. This suggests that early hormonal treatment can be beneficial in managing the cancer and its spread.Rate this question:

In castration resistance Prostate cancer, all are true except
- A.
Occurs usually after 18 to 24 months after starting androgen deprivation therapy.
- B.
PSA levels are increased
- C.
Increase testosterone level >50% ng/dl.
- D.
Androgenic treatment should be stopped.
- E.
Androgen treatment should be continued
Correct Answer(s)
C. Increase testosterone level >50% ng/dl.
D. Androgenic treatment should be stopped.Explanation
In castration-resistant prostate cancer, all the given options are true except for "Increase testosterone level >50% ng/dl" and "Androgenic treatment should be stopped." In castration-resistant prostate cancer, the cancer cells have become resistant to the effects of androgen deprivation therapy (ADT). This means that despite the reduction in testosterone levels, the cancer cells continue to grow. Therefore, PSA levels are increased and androgenic treatment should be continued, rather than stopped. Additionally, the increase in testosterone level >50% ng/dl is not a characteristic feature of castration-resistant prostate cancer.Rate this question:

Traditional and recommended castrate levels of testosterone is:
- A.
32
- B.
<50
- C.
15
- D.
<20
Correct Answer
B. <50Explanation
The traditional and recommended castrate levels of testosterone are indicated by the value "<50". This means that the testosterone level should be below 50 units in order to achieve castration. This is a commonly accepted threshold for testosterone suppression in medical practice.Rate this question:

Lower levels of castrate testosterone are associated with an increase in progression-free survival (PFS)
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Lower levels of castrate testosterone are associated with an increase in progression-free survival (PFS) because testosterone plays a crucial role in the growth and proliferation of prostate cancer cells. By reducing the levels of testosterone through castration or hormone therapy, the growth of cancer cells can be slowed down or halted, leading to an increase in progression-free survival. This association has been supported by various studies and is an important factor to consider in the management of prostate cancer.Rate this question:

50 ng/dL testosterone lcut-off is associated with increased time to CRPC
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
A testosterone cut-off of 50 ng/dL is not associated with increased time to CRPC. This means that having a testosterone level below 50 ng/dL does not necessarily lead to a longer time before developing castration-resistant prostate cancer (CRPC). The statement implies that there is no correlation between the testosterone cut-off and the time it takes for CRPC to develop.Rate this question:

Failure to maintain castration levels of testosterone is generally low across GnRH agonists
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
GnRH agonists are medications used to lower testosterone levels in individuals, often as a treatment for conditions such as prostate cancer or endometriosis. These medications work by suppressing the production of testosterone in the body. Therefore, it is expected that the failure to maintain castration levels of testosterone would be low across GnRH agonists. In other words, these medications are generally effective in reducing testosterone levels to the desired castration levels. Hence, the statement "Failure to maintain castration levels of testosterone is generally low across GnRH agonists" is true.Rate this question:
