Colorectal Cancer Radiation Therapy
Steps Involved in IVF:
Procedure Description
Radiation therapy for colorectal cancer involves the use of high-energy radiation to target and destroy cancer cells. This form of therapy is particularly effective for rectal cancers, where it is often used before or after surgery to shrink tumors or eradicate remaining cancer cells. There are different types of radiation therapy used for colorectal cancer, each tailored to the patient’s condition and stage of cancer.
1. External Beam Radiation Therapy (EBRT)
This is the most common type of radiation therapy for colorectal cancer. It involves directing radiation beams at the cancerous area from outside the body. Advanced techniques like Intensity-Modulated Radiation Therapy (IMRT) or Volumetric Modulated Arc Therapy (VMAT) allow for precise targeting, minimizing damage to healthy tissues around the tumor.
2. Brachytherapy
Brachytherapy involves placing a small radioactive source directly inside or near the tumor in the rectum. This internal radiation allows for a higher dose of radiation in a localized area, making it ideal for cases where the tumor is very close to sensitive structures. This approach is less commonly used but can be highly effective in certain circumstances.
3. Intraoperative Radiation Therapy (IORT)
This technique is used during surgery. Once the surgeon has removed most of the tumor, radiation is delivered directly to the area, minimizing exposure to surrounding healthy tissues. IORT is particularly useful in cases of locally advanced rectal cancer, where achieving clean surgical margins may be challenging.
Radiation therapy can be combined with chemotherapy to enhance the cancer-killing effect, a combination known as chemoradiation. The choice of therapy depends on various factors, including the stage of cancer, location of the tumor, and the patient's overall health.
Procedure Duration
Radiation therapy for colorectal cancer varies in duration depending on the specific approach and treatment goals. Understanding the phases and expected recovery time can help patients plan for their treatment journey.
1. Treatment Planning and Simulation
Before the first radiation session, a thorough planning process takes place. This typically involves CT or MRI scans to map the precise location of the tumor and surrounding tissues. The radiation oncologist will then create a tailored treatment plan. This planning phase may take 1-2 weeks but is crucial for the accuracy of the therapy.
2. Treatment Sessions
For external beam radiation therapy, the actual treatment sessions usually take place over several weeks. A standard course of radiation involves daily treatments (Monday through Friday) for 5 to 6 weeks, with each session lasting about 15 to 30 minutes. Brachytherapy, on the other hand, may require fewer sessions since the radiation is more concentrated, while intraoperative radiation is delivered in a single dose during surgery.
3. Recovery and Side Effects
Recovery from radiation therapy is gradual, with most patients experiencing side effects that peak towards the end of the treatment course and begin to resolve a few weeks after therapy concludes. Common side effects include fatigue, skin irritation, and gastrointestinal symptoms like diarrhea or cramping. Long-term recovery can take a few months, especially if combined with surgery.
Benefits
Radiation therapy offers several critical advantages in the treatment of colorectal cancer:
- Effective Tumor Shrinkage: Reduces the size of the tumor, making surgical removal easier and more successful.
- Increased Survival Rates: When combined with surgery and chemotherapy, radiation therapy significantly improves survival rates in colorectal cancer patients.
- Symptom Control: Helps manage symptoms such as pain, bleeding, or bowel obstruction, improving the patient’s quality of life.
- Targeted Treatment: Modern radiation techniques like IMRT minimize damage to surrounding healthy tissues.
- Prevention of Recurrence: Postoperative radiation can help eradicate microscopic cancer cells, reducing the risk of cancer returning.

Risks & Considerations
While radiation therapy is a highly effective treatment option, there are several risks and considerations that patients should be aware of:
- Radiation-Induced Side Effects: Common side effects include fatigue, diarrhea, skin irritation, and abdominal discomfort. These symptoms are usually temporary but can be distressing.
- Long-term Effects: In some cases, radiation therapy may cause long-term damage to nearby organs, leading to bowel or bladder issues, especially if the radiation is delivered near sensitive tissues.
- Fertility Concerns: Radiation therapy targeting the pelvic area can affect reproductive organs, potentially leading to infertility.
- Risk of Secondary Cancers: Although rare, radiation therapy can increase the risk of developing secondary cancers due to the exposure of healthy tissues to radiation.
- Complications with Other Treatments: Combining radiation therapy with chemotherapy or surgery may increase the likelihood of complications, requiring careful coordination between treatment teams.
How to Choose the Right Doctor and Hospital
Selecting the right medical team is crucial for the success of colorectal cancer radiation therapy. Patients should prioritize healthcare providers with a strong track record in oncology and advanced radiation technologies.
When considering a destination for treatment, research the experience and credentials of the radiation oncologists and the technology available at the facility. Ensure that the hospital offers comprehensive cancer care, including access to other necessary treatments such as chemotherapy or surgery.
Patients should also consider hospitals accredited by international health organizations to ensure quality standards. However, it is equally important to read reviews and testimonials from previous patients to get a better understanding of the care provided.

Frequently Asked Questions
What actually happens during hyperstimulation of the ovaries?
The patient will take injectable FSH (follicle stimulating hormone) for eight to eleven days, depending on how long the follicles take to mature. This hormone is produced naturally in a woman’s body causing one egg to develop per cycle. Taking the injectable FSH causes several follicles to develop at once, at approximately the same rate. The development is monitored with vaginal ultrasounds and following the patient’s levels of estradiol and progesterone. FSH brand names include Repronex, Follistim, Menopur, Gonal-F and Bravelle. The patient injects herself daily.
What happens during egg retrieval?
When the follicles have developed enough to be harvested, the patient attends an appointment where she is anesthetized and prepared for the procedure. Next, the doctor uses an ultrasound probe to guide a needle through the vaginal wall and into the follicle of the ovary. The thin needle draws the follicle fluid, which is then examined by an embryologist to find the eggs. The whole process takes about 20 minutes.
What happens to the eggs?
In the next step, the harvested eggs are then fertilized. If the sperm from the potential father, or in some cases, anonymous donor, has normal functionality, the eggs and sperm are placed together in a dish with a nutrient fluid, then incubated overnight to fertilize normally. If the sperm functionality is suboptimal, an embryologist uses Intracytoplasmic Sperm Injection to inject a single sperm into a single egg with an extremely precise glass needle. Once fertilization is complete, the embryos are assessed and prepared to be transferred to the patient’s uterus.
How are the embryos transferred back to the uterus?
The doctor and the patient will discuss the number of embryos to be transferred. The number of successfully fertilized eggs usually determines the number of eggs to be placed in the uterus. Embryos are transferred to the uterus with transabdominal ultrasound guidance. This process does not require anesthesia, but it can cause minor cervical or uterine discomfort. Following transfer, the patient is advised to take at least one days bed rest and two or three additional days of rest, then 10 to 12 days later, two pregnancy tests are scheduled to confirm success. Once two positive tests are completed, an obstetrical ultrasound is ordered to show the sac, fetal pole, yolk sac and fetal heart rate.
Embryoscope©
Built into this technology there is a microscope with a powerful camera that allows the uninterrupted monitoring of the embryo during its first hours of life. In this way, we can keep a close eye on the embryo, from the moment when the oocyte is inseminated and begins to divide into smaller and smaller cells, until it can be transferred to the uterus.
