Our Summary
This research paper compares the findings of three different methods used to detect prostate cancer: multiparametric magnetic resonance imaging (mpMRI), fusion prostate biopsy, and histopathology after radical prostatectomy.
From 2018 to 2020, 259 patients had an mpMRI scan, and any suspicious areas were graded on a scale of 3-5. All of these patients then underwent a fusion biopsy. Prostate cancer was diagnosed in 186 of these patients. Just over half of these patients then had a surgical procedure to remove the prostate, while the rest opted for radiotherapy or active surveillance.
The researchers found that in about 55% of the cases where the prostate was removed, there were additional cancerous lesions that hadn’t been detected by the mpMRI. In around 23% of these cases, the undetected lesions had a Gleason score of 7 or higher, indicating a more aggressive form of cancer.
The conclusion was that up to 10% of clinically significant prostate cancers might be missed by mpMRI. After surgery, some patients’ cancer was found to be more serious than initially thought, with many additional findings being intermediate or high-risk tumors.
In simpler terms, the paper suggests that while mpMRI is a useful tool for diagnosing prostate cancer, it may not catch every case, and some tumors might be more aggressive than they first appear.

Doctor’s Tip
Therefore, it is important for patients to understand the limitations of mpMRI and to discuss all treatment options with their healthcare provider. Additionally, patients should be aware that a prostate biopsy may still be necessary to accurately determine the extent and aggressiveness of the cancer. It is always best to be informed and proactive about your health, so don’t hesitate to ask your doctor any questions or voice any concerns you may have about your prostate biopsy procedure.
Suitable For
As a result, prostate biopsy is typically recommended for patients who have suspicious findings on an mpMRI scan, especially those with a high Gleason score or other risk factors for aggressive prostate cancer. Additionally, patients with elevated prostate-specific antigen (PSA) levels or other symptoms suggestive of prostate cancer may also be recommended for a biopsy. Overall, prostate biopsy is recommended for patients who are at risk of prostate cancer or who have abnormal findings on imaging or blood tests.
Timeline
Before the prostate biopsy, a patient typically undergoes a series of tests, including a physical examination, blood tests, and a digital rectal exam. If the results suggest a potential issue with the prostate, the patient may then undergo a multiparametric magnetic resonance imaging (mpMRI) scan to identify any suspicious areas. If abnormalities are detected, the patient will then undergo a fusion biopsy, where a needle is used to collect tissue samples from the prostate for further analysis.
After the biopsy, the patient may experience some discomfort or minor bleeding, which usually subsides within a few days. The tissue samples collected during the biopsy are then examined by a pathologist to determine if cancer is present and to assess the grade and aggressiveness of the tumor.
Depending on the results of the biopsy, the patient and their healthcare team will discuss treatment options, which may include surgery, radiation therapy, or active surveillance. If surgery is chosen, the patient will undergo a radical prostatectomy to remove the prostate gland. After surgery, the removed tissue is examined to confirm the presence of cancer and to identify any additional cancerous lesions that may not have been detected by the initial mpMRI scan.
Overall, the timeline for a patient before and after a prostate biopsy involves a series of tests, procedures, and consultations with healthcare providers to diagnose and treat prostate cancer effectively.
What to Ask Your Doctor
Some questions a patient should ask their doctor about prostate biopsy based on the information presented in the research paper include:
- What is the accuracy rate of multiparametric magnetic resonance imaging (mpMRI) in detecting prostate cancer?
- How common is it for mpMRI to miss clinically significant prostate cancers?
- What are the potential risks or limitations of relying solely on mpMRI for prostate cancer detection?
- What additional diagnostic tests or procedures may be recommended if a prostate cancer is suspected but not detected by mpMRI?
- How does fusion biopsy compare to mpMRI in terms of detecting prostate cancer?
- What are the potential benefits of undergoing a fusion biopsy in addition to mpMRI?
- How often do undetected cancerous lesions with high Gleason scores (7 or higher) occur in patients who have undergone mpMRI and fusion biopsy?
- How might the presence of undetected high-risk tumors impact treatment options or recommendations?
- What are the implications of the findings that some prostate cancers may be more aggressive than initially thought after surgery?
- How can patients ensure they are receiving comprehensive and accurate information about their prostate cancer diagnosis and treatment options?
