The ADT medical abbreviation usually means androgen deprivation therapy, a hormone treatment that lowers testosterone and is used mainly for prostate cancer. In hospital operations and health records, the same three letters can also mean admission, discharge and transfer, the tracking of when patients arrive, move and leave.
Patients tend to meet the first meaning in an oncology or urology note, a medication list, or a lab order for a PSA check. Records staff, coders and IT teams meet the second one in census reports and data feeds. This page covers each meaning in turn, with sample chart lines and the hints that reveal which one is meant.

ADT medical abbreviation cancer meaning
Most prostate cancers use male hormones, called androgens, as fuel. Androgen deprivation therapy cuts the supply. It may be given by injection or implant that tells the body to stop making testosterone, by pills that block androgens from acting on cancer cells, or, less often today, by surgery to remove the testicles. Many teams call the goal castrate levels of testosterone, a medical phrase for very low.
ADT is used for cancer that has spread, for cancer that returns after surgery or radiation, and together with radiation for some higher risk cancers that have not spread. It controls the disease for a time rather than removing it. The length of treatment varies a great deal, from several months to years, and is set by the cancer team.
Reading ADT in an oncology note
An oncology plan line can hold a whole treatment story. Each piece of this sample gets its own row.
| Text in the note | Plain meaning |
|---|---|
| mHSPC | Metastatic hormone sensitive prostate cancer: spread, still responding to hormone treatment |
| on ADT | Currently receiving androgen deprivation therapy |
| leuprolide q3 months | A generic injectable hormone medicine, given every three months |
| PSA 0.4, T <20 | PSA level and testosterone level at the last check |
Other generic names you may see near ADT include goserelin, degarelix, relugolix and bicalutamide. Some plans pair ADT with a newer oral hormone medicine or with chemotherapy. The PSA page explains the blood marker that teams watch most closely.
What patients often notice during hormone therapy
Lowering testosterone affects the whole body, so side effects are common and are a regular topic at follow up visits. People on ADT often describe hot flashes, tiredness, lower sex drive, erection problems, weight gain around the middle, loss of muscle and mood changes. Over longer periods, bones can thin and the risk of diabetes and heart problems can rise.
For that reason, care teams may order bone density scans, check blood sugar and cholesterol, and encourage regular activity. Some side effects ease if therapy is paused, which some plans do on purpose. Any changes to the schedule are a decision for the treating team.
Clinic handoff: "Pt on ADT x 2 yrs, c/o hot flashes, DEXA ordered." This means the patient has been on androgen deprivation therapy for two years, is reporting hot flashes, and has a bone density scan ordered to check for thinning.
Admission, discharge and transfer in hospital records
In the business side of health care, ADT names the events that move a patient through a hospital stay: being admitted, being moved to another unit or bed, and being discharged. Electronic records send ADT messages, standard data notices that tell the lab, pharmacy, billing and other systems where each patient is right now.
Bed boards, census lists and staffing reports are built from these events. A records clerk might say "the ADT feed is down" when the systems stop sharing location updates. This meaning almost never appears in a medication list or a cancer plan, so the setting usually settles it.
ADT acronym medical clues for the right meaning
A strict acronym is said as a word, while ADT is spoken letter by letter, but people search for it both ways. Use the surrounding words to decide which one you are reading.
| Clue in the text | Likely meaning |
|---|---|
| Prostate, PSA, testosterone, injection, oncology | Androgen deprivation therapy |
| Census, bed, unit, interface, registration, feed | Admission, discharge and transfer |
| Medication list or care plan | Androgen deprivation therapy |
| IT ticket or data report | Admission, discharge and transfer |

Frequently asked questions
What does ADT mean for prostate cancer?
It means androgen deprivation therapy, a treatment that lowers testosterone or blocks its effect. Since most prostate cancers rely on these hormones to grow, lowering them can shrink or slow the cancer for a time.
Is ADT the same as chemotherapy?
No. ADT is hormone therapy, which works by changing hormone levels, while chemotherapy uses drugs that kill fast dividing cells. Some treatment plans use both together.
What is an ADT message in a hospital?
It is an electronic notice that a patient was admitted, moved or discharged. These messages keep the lab, pharmacy, billing and bed systems in step with where each patient is.
How long do people stay on ADT?
It varies widely. Some plans use it for several months alongside radiation, while others continue it for years when cancer has spread. The cancer team sets the length based on the situation.
