Cervical Cancer Radiotherapy

Introduction

Radiotherapy for cervical cancer is a mainstay in the treatment of cervical cancer, particularly when surgery is not an option or the disease is advanced. Radiotherapy involves the use of high-energy radiation to kill and destroy cancer cells, usually in combination with chemotherapy for better results. It is a critical component in curative and palliative treatment regimens, enhancing survival and quality of life.

About Cervical Cancer

Cervical cancer starts in the cervix, which is the lower portion of the uterus that leads into the vagina. The majority are due to chronic infection with high-risk HPV types. It tends to advance slowly, so early detection by Pap tests and HPV testing is feasible. Symptoms such as irregular vaginal bleeding, pain with intercourse, or pelvic pain do not appear until later stages.

Worldwide, cervical cancer is the fourth most prevalent female cancer and disproportionately affects women in low- and middle-income countries.

Indications for Cervical Cancer Radiotherapy

Radiotherapy is indicated in:

• Locally advanced cervical cancer (Stages IB2 to IVA)

• Post-operative treatment in high-risk cases (positive margins, lymph node involvement)

• Palliative treatment for symptom control in metastatic or recurrent cases

• When surgery is not possible due to medical or anatomical reasons

Treatment Details

Cervical cancer radiotherapy is usually delivered in one or both of the following forms:

External Beam Radiotherapy (EBRT)

• Delivered from outside the body using a linear accelerator

• Administered 5 days a week over 5-6 weeks

• Targets the cervix, uterus, parametrium, lymph nodes

Brachytherapy (Internal Radiation)

• Radioactive sources placed directly in or near the tumor

• High-dose rate (HDR) or low-dose rate (LDR) options

• Usually follows EBRT to boost the local dose to the cervix

• Delivered over 3-5 sessions (HDR), usually 1-2 times per week

Concurrent Chemoradiation

• Weekly low-dose cisplatin (40 mg/m²) enhances radiation effects

• Improves local control and overall survival in locally advanced cases

Medicines Used

During concurrent chemoradiation, the following drugs are commonly used:

• Cisplatin: Radiosensitizer and standard of care in chemoradiation

• Carboplatin: Used in patients unable to tolerate cisplatin

• 5-Fluorouracil (5-FU): Sometimes used with cisplatin in more aggressive cases

• Anti-emetics and hydration: To manage side effects of chemotherapy

Effectiveness of Cervical Cancer Radiotherapy

• Five-year survival rates range from 60% to 80% in locally advanced cases

• Radiotherapy combined with chemotherapy improves survival by 30-40%

• Effective even in cases where surgery is not feasible

• Helps reduce recurrence and controls symptoms in advanced stages

Risks and Side Effects

Radiotherapy for cervical cancer is generally safe but may have short-term and long-term side effects.

Short-term side effects:

• Fatigue

• Diarrhea

• Nausea

• Bladder irritation (cystitis)

• Skin irritation in pelvic area

Long-term side effects:

• Vaginal stenosis

• Premature menopause

• Chronic bowel/bladder issues

• Lymphedema

• Secondary cancers (rare)

Side effects can often be managed with medications and support from the care team.

Recovery and Aftercare

During treatment:

• Regular hydration and a balanced diet

• Skincare and hygiene for irradiated area

• Use of medications for side effects

After treatment:

• Follow-up with imaging and pelvic exams every 3-6 months for 2 years

• Use of vaginal dilators and lubricants to prevent stenosis

• Psychosocial counseling and support groups

• Pelvic floor rehabilitation in case of urinary or sexual dysfunction

Most patients can return to normal activities a few weeks after completing treatment, depending on the intensity of side effects.

Cost and Availability

Radiotherapy for cervical cancer is widely available in cancer centers across the globe. However, the cost may vary depending on:

• Stage and extent of the disease

• Type of radiotherapy used (EBRT, IMRT, or brachytherapy)

• Combined use of chemotherapy

• Duration of treatment and follow-up

In general, radiotherapy is more affordable in countries like India, China, and Thailand compared to the US or Western Europe.

Patient Experiences

Many patients report a positive outcome with radiotherapy, especially in cases where surgery was not an option. Common experiences include:

• Reduction in bleeding and pain within weeks

• Gradual return of energy levels post-treatment

• Mixed feelings about side effects, especially fatigue and vaginal changes

• Emphasis on the importance of counseling, family support, and regular follow-up

Patient testimonials often highlight the importance of early diagnosis and personalized treatment planning.

• Cost-effective packages for domestic and international patients

Ongoing Clinical Trials in China for Cervical Cancer Radiotherapy

Some ongoing and recent trials in China include:

• Trial of image-guided adaptive brachytherapy: Investigating improved targeting with reduced toxicity

• Phase II/III trial of IMRT with cisplatin vs 3D-CRT: Evaluating outcomes in locally advanced cervical cancer

• Trial combining immunotherapy with radiotherapy: Aimed at enhancing anti-tumor response

• Use of AI in radiotherapy planning: Testing machine learning for dose optimization

FAQ

Is radiotherapy alone enough for cervical cancer?

In early stages, surgery is preferred, but in locally advanced cases, chemoradiotherapy is the gold standard.

How painful is radiotherapy for cervical cancer?

The procedure itself is painless. Side effects like fatigue and diarrhea may cause discomfort but are manageable.

How many sessions are required?

Typically 25–30 EBRT sessions followed by 3–5 brachytherapy sessions.

Can I have children after radiotherapy?

Radiotherapy usually affects fertility. Fertility preservation options should be discussed before treatment.

Does radiotherapy cure cervical cancer?

Yes, in many cases of localized or locally advanced disease, radiotherapy offers curative potential.

What precautions should I take during treatment?

Hydrate well, avoid spicy food, use gentle skincare, and follow medical advice.

Is it safe to travel during radiotherapy?

Short trips may be fine, but regular sessions are critical, so extended travel should be postponed.

What is the success rate?

Five-year survival is 60–80% for locally advanced cervical cancer with proper treatment.
