Only the prostate gland releases PSA, so your numbers should drop to almost zero within 4 weeks after your surgery. A test result above 0.2 ng/mL a few months after your procedure could be a sign that yourprostate cancerhas come back. This is called a biochemical recurrence. If your numbe...
Your doctor will also consider other things, including what your PSA levels were before you had cancer, your overall health, and whether you've had radiation therapy. After radiation therapy it may take 1-2 years for your PSA to drop to its lowest level. ...
【29】How is the PSA test used in men who have been treated for prostate cancer? The PSA test is used to monitor men after surgery or radiation therapy for prostate cancer to see if their cancer has recurred (com...
After surgery or radiation, medical providers watch for a cancer relapse with PSA and PSADT test results. Those numbers plus your original risk category are considered together when deciding what treatment course to follow—the faster the PSADT and the higher your risk category, the more aggressive...
On univariate analysis, preferential hormone therapy (PHT) (p=0.022), higher PSA at SRT (p=0.005), and higher PSA after surgery (p=0.003) were related to a shorter biochemical survival period. On multivariate analysis, lower PSA at SRT (p=0.016), higher radiation dose (p=0.007), and ...
After radiation, patients were followed every 6 months by a radiation oncologist and a urologist with physical examination and PSA analysis. Imaging to exclude metastastic disease was performed at the physician's discretion, as was the prescription of hormone therapy for biochemical or clinical failu...
After sterilization with 100% Ethanol and UV radiation (20 min both sides), mPCL scaffolds were seeded with osteoprogenitor cells (800,000 cells/scaffold) in a 5 µL drop in the centre of the scaffolds. After attachment (4 h), scaffolds were cultured in growth media (GM) (MEM-...
However, because of the small patient numbers, these results will need to be validated with longer follow up. Radiat. Oncol. Invest. 7:106–110, 1999. © 1999 Wiley-Liss, Inc.Özer AlganDepartment of Radiation OncologyWayne H. Pinover...
Cells at the indicated numbers were implanted subcutaneously or orthotopically (in the dorsal prostate) in 50% Matrigel in the three types of hosts. All tumors were harvested in ∼2 months. d The triple marker-positive and -negative LAPC9 cells were purified from the xenograft tumors that ...
Moreover, the bounce in PSA invariably occurs after the isotope has effectively decayed (Figure 2) and the radiation effect cannot by itself explain this phenomenon. It is also possible to show intuitively that a model with two equations that account for tumour growth, PSA production and the ...
