Do bone Mets still exist with no bone met?
reviewing the CT scan showed that the chemo was not effective, spinal bone mets still exist and... with no bone met. And thereafter sometime, you have bone mets. Did you notice pain on the bone...
Can you have metastasized PC with no PSA?
John T gave the best answer..Some, rare, forms of metastasized PC produce little or no PSA....Some forms of localized PC, usually Gleason 9 and 10, produce very little PSA, fooling doctors. The DRE spots it, and biopsy confirms it.. I once had excruciating hip pain.
Are bone Mets active or just scar tissue?
The bone mets seem mostly inactive and just scar tissue. Aggressive variants don't have Just one lytic lesion.. ( and that might in reality probably misread) IMO...He is responding beautifully to Lupron and the proof is his PSA is 0.06 and ALP 88.
What do you think about PSA in prostate cancer?
PSA is also currently the most useful marker for assessing the level of bone involvement in prostate cancer. Diagnosis of bone metastases is accomplished by a bone scan. This thread just shows how unpredictable PC can be.
How long can you live after prostate cancer recurrence?
Approximately 20 to 30 percent of patients with prostate cancer will show signs of recurrence at some point in their lives. However, the relative survival rates remain high; 94 percent of patients live at least 15 years after their original diagnoses.
What is the success rate of radiation therapy for recurrent prostate cancer?
In contrast with the results of primary radiotherapy for localized prostate cancer,8,9 the reported success rates of salvage radiotherapy range between 10% and 50%, suggesting that the majority of unselected patients with an increasing PSA level have occult metastases and do not benefit from salvage radiotherapy.
What is a worrisome PSA doubling time?
For patients with relatively constant PSA, such as a change from 6 to 6.1 ng/ml over the course of a year, doubling time become rather unstable and such patients are normally categorized in terms of “doubling time > 10 years” or similar.
What is the expected PSA after radiation therapy?
Recent studies have shown that for optimal results, PSA levels should be lower than 1 ng/ml, and even lower than 0.5 ng/ml. Levels that are above 1 or 2 ng/ml 12 to 18 months following completion of radiation treatments are very worrisome, because they indicate that the cancer may not have been eradicated.
Does prostate cancer come back after radiation treatment?
Prostate cancer can come back, even after you've had treatment and your doctor declared you cancer-free. Prostate cancer that returns after treatment is called recurrent prostate cancer. Prostate cancer returns for a couple of reasons: Some cancer cells were left behind after surgery or radiation therapy.
What is the average number of radiation treatments for prostate cancer?
Only five treatment sessions are needed. Each one is about three to four minutes long. The entire course can be completed in a little over a week. By comparison, standard radiation requires close to 45-50 sessions over nine to ten weeks.
Can PSA double in 2 months?
We can definitely correlate post-treatment relapses with pretreatment PSA velocity, or how quickly the PSA rises. We did a study showing that a pretreatment PSA that increased by more than 2 ng/ml in a year is the strongest predictor that the PSA will double in less than three months after surgery.
How quickly do PSA levels rise?
In the overall study population, the mean change in PSA levels was 2.9% per year and the rate of change in PSA increased modestly with age (P < . 001). Overall, men who developed prostate cancer experienced a more rapid percent change in PSA per year than men who did not (P < . 001).
What should PSA be 2 years after radiation?
Summary: Prostate cancer patients who have a prostate-specific antigen value of less than or equal to 1.5 at two years after external beam radiation therapy are less likely to have a cancer recurrence and cancer-related death, according to a new study.
What should PSA levels be 3 months after radiation?
Patients were characterized by 3-month post-RT PSA values: <0.10 ng/mL, 0.10 to 0.49 ng/mL, and ≥0.50 ng/mL. The researchers found that a higher 3-month PSA level was strongly associated with biochemical progression-free survival (bPFS), prostate cancer-specific survival (PCSS), and overall survival (OS).
What should PSA be 6 months after radiation?
The median PSA 6 months after EBRT was 0.1 ng/mL (range, 0-19 ng/mL), and 310 patients (58.3%) had a 6-month PSA ≤0.1 ng/mL. Multivariable analysis (MVA) demonstrated that a 6-month post-EBRT PSA of >0.1 ng/mL was an independent predictor of worse bRFS (hazard ratio [HR] = 2.518; P<. 0001), DMFS (HR=3.743; P<.
What is the average PSA for a 70 year old?
3.5-4.5: Normal for a man 60-70 yrs. 4.5-5.5: Normal for a man 70-80 yrs.
