Unlike
other cancer treatments, brachytherapy has a history that spans over a
century. In 1901, Pierre Curie, a
physicist from France, first suggested that radiation could be used to treat
cancer to one of his colleagues, a doctor named Henri-Alexandre Danlos. Dr.
Danlos tested the idea and found that radiation caused tumors to shrink. Early
techniques of brachytherapy were first performed at the Curie institute by Dr.
Danlos. Over the next fifty years, doctors around the globe (through trial and
error) expanded clinical applications of brachytherapy to include cervical,
prostate and breast.
Towards
the end of the 20th century, brachytherapy received a huge stimulation from
imaging technologies such as magnetic resonance imaging (MRI), computer
tomography (CT) and ultrasound. This allowed doctors to place the radioactive
materials in precise locations in the body. RTi may be broken down into
permanent and temporary modalities.
Cryoablation
is the use of freezing temperatures to erode and destroy specific tissue cells.
What is known as modern cryoablation therapy began in the early 1960s when
cryosurgical probes cooled by liquid nitrogen were introduced. In the 1970s,
handheld cryoablation devices were developed for cardiac purposes. As time went
on, cryoablation has evolved into an exact science. Modern cryoablation can be
described in four stages: freeze, thaw, hemorrhage and inflammation and
replacement fibrosis. The theory claims that, during the initial phase, the
cellular metabolism of the tissue is slowed and the area experiences
progressive hypothermia. Once the thaw begins, the tissue experiences cellular
damage, which culminates in vascular obliteration and ischemic cellular
necrosis. Cryoablation uses compressed argon gas as a coolant. As the gas
progresses through the needle, the end of the needle develops an ice ball that
is then used to “ablate” the desired tissue.
The
market for cryoablation is a little bit different from other ablations. Of all
procedures performed in 2015, half of them originated from capital units that
were already installed and the other half came from rentals. As such, the
cryoablation models in this chapter are split into rentals (which include
disposables), disposables used by an existing installed base and the machines
themselves. When a hospital needs to perform a cryo procedure that does not own
the capital equipment, they can have it dropped off (complete with the
disposables) for a fee. For hospitals that do not have the funds or lack a
sufficient customer base, this arrangement can be desirable.
Internal
radiation therapy (RTi), also known as brachytherapy, is a form or RT that puts
the radioactive material inside the patient either via a catheter or a needle.
In terms of its placement, RTi may be administered as intracavitary or
interstitial. In the case of intracavitary, the radioactive material is placed
inside a cavity in the body such as in the rectum or uterus; in the case of
interstitial, the radioactive material is placed on/near the cancer but not
inside a body cavity. The most common form of brachytherapy involves the
placement of “seeds” inside the body involving differing durations and
radioactivity. Each seed is approximately the size and shape of a small grain
of rice.
