Pros And Cons Of Radiation Therapy

How Does Radiotherapy Work

PROS & CONS: Prostate Cancer Radiation vs Surgery – Dr. David Samadi

Radiotherapy aims to destroy prostate cancer cells without causing too much damage to healthy cells. External beam radiotherapy is high-energy X-ray beams targeted at the prostate from outside the body. These X-ray beams damage the cancer cells and stop them from growing and spreading to other parts of the body . Radiotherapy permanently damages and kills the cancer cells, but healthy cells can repair themselves and recover more easily.

Radiotherapy treats the whole prostate. It aims to treat all the cancer cells, including any that have spread to the area just outside the prostate. The treatment itself is painless but it can cause side effects that may cause you problems.

You may have radiotherapy to a wider area, including the nearby lymph nodes, if there is a risk that the cancer has spread there. Lymph nodes are part of your immune system and are found throughout your body. The lymph nodes in your pelvic area are a common place for prostate cancer to spread to. If you do have radiotherapy to a wider area, you will be more likely to get side effects.

Proton Therapy Versus Carbon Ion Therapy

Carbon ion radiotherapy is similar to proton therapy, except it uses carbon ions instead of protons. Carbon ions are heavier than protons, so they can deliver more radiation to the tumor and cause more damage to cancer cells. International research shows promising results in cancer survival rates with carbon ion therapy. However, there are presently no centers in the U.S. that offer CIRT.

Da Vinci Robotic Prostatectomy/robotic

Surgery is performed by a trained and skilled surgeon through the use of a computer-enhanced robotic surgical system positioned near the operating table. The Da Vinci Robotic surgical system is made up of three major components, which include a vision system with high magnification and resolution, robotic arms and instruments, and a console to provide the surgeon with a view of the operative field and control the instruments.

With many advantages, the disadvantages can follow up always. Indeed, breast cancer has side effects to a large extent. So, as radiation therapy is targeted to the affected part of the skin, it is natural for the skin to change its color. Even, swelling in the skin becomes quite common. To add on, uneasiness as well as pain forms in the best after being treated with radiation therapy.

Sometimes, stiffness in the breast after breast cancer due to radiation is mostly common among women. The patient also feels tired most of the time after being given radiation therapy. They turn out to be irritating and feel the victim of sore throat as well. The main traumatic side effect can be the shape change of the breast. Here women face sleepless nights as they become much concerned after their treatment. Other problems that can show up include having heart diseases as well as certain lung ailments as well.

Thus, breast cancer in itself is a big disease and on top of that, having the side effects after treating it with radiation can be really heartbreaking.

Going Through Radiation Therapy

Radiation therapy can harm normal tissue, so its carefully planned and precisely delivered. This helps ensure the radiation kills as many cancer cells as possible while doing as little harm as possible to other parts of your body.

Radiation therapy is planned specifically for your breast cancer, the shape of your body and your internal anatomy. This is why sessions cant be split between different treatment centers.

Your treatment plan is based on:

  • The tumor size, type and location
  • The number of lymph nodes with cancer
  • The type of breast surgery you had
  • The shape of your breast or chest wall, and the shape and location of nearby organs

Crucial Pros And Cons Of Radiation Oncology That One Should Know About

Radiation oncology pertains to the scientific study and development of radiation therapies to kill cancer cells and prevent their reoccurrence. Radiation therapy is one of the most sought cancer treatment methodologies. However, as with any other medical treatments, there are certain pros and cons of radiation therapy. One of the biggest research projects that are currently being worked upon in the field of radiation oncology are related to addressing some of the disadvantages of radiation therapy.

There was a time when cancer was considered to be a terminal disease. However, nowadays, due to massive leap in the technological advancements in the field of medical research and innovation of newer medical therapies, cancer, if detected in early stages, can be cured completely. Several cancer treatments such as chemotherapy, immunotherapy, cryoablation, radiation therapy, etc. have been developed which have made this possible.

Advantages And Disadvantages Of Radiation Therapy

The Pros and Cons of Proton Therapy | Mark Scholz, MD | PCRI

The advantages of radiation therapy include:

  • death of a large proportion of cancer cells within the entire tumor
  • death of microscopic disease at the periphery of the tumor that would not be visible to the naked eye
  • ability to shrink tumors
  • relative safety for the patient
  • synergy with systemic therapy
  • organ preservation (e.g. not removing a breast, larynx, or part of the gastrointestinal tract, which would have significant negative impact on a patients quality of life
  • possible stimulation of an immune response against the tumor

The disadvantages of radiation therapy include:

  • damage to surrounding tissues , depending on how close the area of interest is located to the tumor
  • inability to kill tumor cells that cannot be seen on imaging scans and are therefore not always included on the 3D models of radiation planning
  • inability to kill the all cancer cells in tumors
  • inability to relieve mass effect in certain parts of the body , thereby requiring surgery
  • poor killing of cancer cells in areas that do not have a good supply of oxygen
  • increased incidence in wound complication and poor healing
  • inconvenience of radiation therapy
  • contraindications to radiation therapy

What Types Of Radiotherapy Are There

There are two common types of external beam radiotherapy:

  • intensity-modulated radiotherapy
  • 3-dimensional conformal radiotherapy .

You may also hear about image guided radiotherapy . This is part of all radiotherapy treatments. Taking images of the prostate before each treatment allows your radiographer to make small changes to the area that is going to be treated, in case the prostate has moved slightly since your last treatment session. This makes sure the surrounding healthy tissue gets as little radiation as possible. It also makes sure the whole prostate is treated.

Intensity-modulated radiotherapy

This is the most common type of external beam radiotherapy in the UK. A computer uses the scans from your radiotherapy planning session to map the location, size and shape of your prostate. The radiotherapy machine gives beams of radiation that match the shape of the prostate as closely as possible. This helps to avoid damaging the healthy tissue around it, reducing the risk of side effects.

The strength of the radiation can be controlled so that different areas get a different dose. This means a higher dose of radiation can be given to the prostate without causing too much damage to surrounding tissue.

3D conformal radiotherapy

As with IMRT, the radiation beams are mapped to the size, shape and position of the prostate. But the strength of the radiation cant be controlled in 3D-CRT, so all areas are treated with the same dose.

Other types of radiotherapy

Proton beam therapy

Proton Beam Radiation Therapy

Proton beam radiation uses beams of protons instead of X-rays. A proton is a particle with a positive electric charge that is in the nuclei of all atoms.

X-rays release energy both before and after they hit their target. But protons release their energy only after traveling a certain distance. So doctors think protons may be able to deliver more radiation directly to the treatment area while possibly doing less damage to nearby healthy tissue. But this is still being studied.

Right now, proton beam radiation is only being used in clinical trials to treat breast cancer. The machines needed to deliver protons are very expensive and are not widely available.

If youre interested in being treated with proton beam therapy, talk to your doctor to find a clinical trial that would be a good fit for your unique situation.

How Are Photon And Proton Beam Therapies Different From Each Other

Although both photon and proton therapies are forms of radiation therapy, there are 2 main differences.a) The type of particle that is aimed at the tumor: Photons such as X-rays are delivered as waves which do not have any charge. They pass through the body and release energy all along the way. A proton is an invisibly-small positively-charged particle. How deeply a proton travels into the body depends on the speed of the proton when it leaves the machine. 15

b) The effect of radiation on cells surrounding the tumor: The energy in photon beams gets absorbed gradually as the beams pass through tissues. Because of this, they cause damage to the tissues they pass through as they travel towards the targeted tumor. If the remaining energy of the beam is not fully absorbed by the tumor, a photon beam can continue to pass through and damage or kill more healthy cells until it exits the patients body.15

Protons release their energy all at once. They do not damage cells they pass through until they release their energy in a single burst. The distance that a proton travels before it releases its energy is determined by how fast it is moving. Proton beams are delivered at speeds that cause almost all of the energy to be released inside the tumor. Because all the radiation energy is targeted at the tumor, little energy is released into the tissues beyond the tumor. This saves the surrounding tissue from any damage.16

What Does External Beam Radiotherapy Involve

You will have your treatment at a hospital radiotherapy department. Youll see a specialist doctor who treats cancer with radiotherapy, known as a clinical oncologist. You may also see a specialist nurse and a specialist radiographer. Theyll talk to you about your treatment plan and ways to manage any side effects.

Before your radiotherapy treatment

Radiotherapy planning session

A week or two before your treatment, youll have a planning session. This is to make sure the radiographers know the exact position, size and shape of your prostate. It will help them make sure the radiotherapy is aimed at your prostate and that the surrounding areas get as little radiation as possible.

During your radiotherapy treatment

You will have one treatment at the hospital five days a week, with a rest over the weekend. You can go home after each treatment.

If you have localised prostate cancer, the course of radiotherapy usually involves 20 treatment sessions over four weeks. You might hear this called hypo-fractionated radiotherapy.

At some hospitals, youll have 37 sessions over seven or eight weeks instead. If you have 37 sessions, youll receive a slightly larger overall dose of radiotherapy but the dose you receive at each session will be lower than if you have 20 sessions.

Its safe for you to be around other people, including children and pregnant women, during your course of radiotherapy. The radiation doesnt stay in your body so you wont give off any radiation.

Radiation Therapy Career: Pros and Cons

The certainty of killing cancer cells following the administration of radiation therapy is always there. Based on the nature of the radiation, it is able to destroy a significant fraction of cancer cells. Some of the cells are destroyed instantly depending on the amount of radiation they have absorbed. On the other hand, some cells are destroyed over time. Those that die after some time usually do so without causing any harm to the body.
