What is hyperfractionated radiation?
(HY-per-FRAK-shuh-NAY-ted RAY-dee-AY-shun THAYR-uh-pee) Radiation treatment in which the total dose of radiation is divided into small doses and treatments are given more than once a day. Hyperfractionated radiation therapy is given over the same period of time (days or weeks) as standard radiation therapy.
What is the meaning of neo adjuvant?
: of, relating to, or being treatment (such as chemotherapy or hormone therapy) administered before primary cancer treatment (such as surgery) to enhance the outcome of primary treatment In certain breast cancer, neoadjuvant therapies reduce recurrences by 50 percent in some situations.—
When is neoadjuvant therapy used?
Neoadjuvant therapy is the pre-operative treatment of tumours with chemotherapy, radiation therapy, and endocrine therapy. It was originally used for its impact on surgery, downstaging tumours, and allowing breast-conserving surgery rather than mastectomy.
What is adjuvant radiation?
Listen to pronunciation. (A-joo-vunt THAYR-uh-pee) Additional cancer treatment given after the primary treatment to lower the risk that the cancer will come back. Adjuvant therapy may include chemotherapy, radiation therapy, hormone therapy, targeted therapy, or biological therapy.
What is Hypofractionation radiation?
Listen to pronunciation. (HY-poh-FRAK-shuh-NAY-ted RAY-dee-AY-shun THAYR-uh-pee) Radiation treatment in which the total dose of radiation is divided into large doses and treatments are given once a day or less often.
What is accelerated radiotherapy?
Listen to pronunciation. (ak-SEH-leh-ray-ted RAY-dee-AY-shun THAYR-uh-pee) Radiation treatment in which the total dose of radiation is given over a shorter period of time (fewer days) compared to standard radiation therapy.
What is neoadjuvant hormone therapy?
Neoadjuvant hormonal therapy (NHT) is, in general, considered to be a suitable option for hormone receptor (HR)-positive patients who are unfit for chemotherapy or surgery, and is increasingly being utilized to achieve tumor downsizing before surgery in postmenopausal women.
What is the difference between salvage radiation and adjuvant radiation?
Two postoperative approaches to reduce risk for relapse are commonly used: Adjuvant radiotherapy (ART), which should be performed within 4 months after surgery, triggered mainly by tumor size and surgical margins, and salvage radiotherapy (SRT), which is performed when prostate-specific antigen (PSA) levels increase …
What is rapid radiation?
RapidArc radiotherapy technology, produced by Varian Medical Systems, is an extremely fast and precise form of image-guided, intensity-modulated radiation therapy (IMRT). Image guidance improves tumor targeting. IMRT shapes the radiation dose so that it conforms closely to the 3D shape of your tumor.

What are adjuvants and example?
Adjuvants augment, stimulate, potentiate, enhance, activate, or modulate the immune response at either cellular or humoral level. Best known examples include Freund’s adjuvant, Bacillus Calmette–Guérin (BCG), Corynebacterium parvum; all of which contain bacterial antigen.
What is neoadjuvant ADT?
Neoadjuvant androgen deprivation therapy (NADT) is systemic therapy administered after the diagnosis of prostate cancer but before locoregional therapy such as radical prostatectomy (RP) or radiation.

What is ADT prostate?
Prostate cancer needs testosterone to grow. Reducing how much testosterone your body makes may slow the cancer’s growth or shrink the cancer temporarily. Testosterone is an androgen (male sex hormone), so this treatment is called androgen deprivation therapy (ADT). It is also known as hormone therapy.
What is arc radiation?
What is RapidArc® radiation therapy? RapidArc® radiation therapy is a technique that combines intensity modulated radiation therapy (IMRT) with rotational arc delivery on the linear accelerator. The treatment consists of 360-degree rotation of the accelerators gantry with the beam focused on the target.
What is IGRT and IMRT?
IGRT uses imaging with the therapy to increase the efficiency by improving the precision and accuracy of the treatment procedure. The IMRT therapy uses high-edged software and sophisticated hardware to vary the intensity and shape of radiation used for different parts of the treatment area.
