Stereotactic Radiotherapy (SRT) Cost in India

Stereotactic Radiotherapy (SRT) is a highly advanced form of radiation therapy that delivers precise, high-dose radiation to tumors with millimeter-level accuracy. Unlike traditional radiotherapy, which may require several weeks of treatment, SRT targets tumors with extreme precision, allowing treatment to be completed in just 1 to 5 sessions.

Globally, SRT has become one of the most trusted radiation techniques due to its combination of accuracy, minimal side effects, and quick recovery. According to international oncology reports, over 1 million patients have been treated with stereotactic radiotherapy in the past decade.

SRT offers over 90% local tumor control in many early-stage brain and lung tumors, making it one of the most effective non-surgical cancer treatments available today. Its precision reduces damage to surrounding healthy tissues by up to 70–80% compared to conventional radiotherapy.

With its ability to deliver powerful radiation safely and accurately, SRT has become a preferred treatment option for patients seeking effective, minimally invasive cancer care with shorter recovery times.

What Is Stereotactic Radiotherapy (SRT)?

Stereotactic Radiotherapy (SRT) is an advanced form of radiation treatment that delivers highly focused, high-dose radiation to tumors with exceptional accuracy. It uses detailed 3D imaging and computer-guided planning to target cancer cells while preserving the surrounding healthy tissues.

SRT differs from conventional radiation in three essential ways:

• It uses multiple narrow radiation beams that converge precisely on the tumor.
• It delivers higher radiation doses per session.
• It requires fewer treatment sessions, often completed within 1 to 5 sessions.

This technique is especially effective for small, well-defined tumors located in areas where surgery may be risky, such as the brain, spine, lungs, liver, and prostate.

Stereotactic Radiosurgery (SRS)

Despite its name, SRS is not a surgical procedure. It is a single-session, high-dose radiation treatment primarily used for:

• Brain tumors
• Arteriovenous malformations (AVMs)
• Certain functional disorders

Stereotactic Body Radiotherapy (SBRT)

SBRT delivers radiation in 3–5 sessions and is used for tumors outside the brain, such as:

• Lung nodules
• Liver tumors
• Spine and bone lesions
• Prostate cancer

Due to its precision, SRT minimizes side effects and enables patients to resume normal activities quickly, making it a preferred option for those seeking a non-invasive yet highly effective treatment for cancer.

When Is Stereotactic Radiotherapy Recommended?

Stereotactic Radiotherapy (SRT) is recommended for small, well-defined tumors located in areas where precision is critical or where surgery may not be possible. It is commonly used when doctors need to treat cancer with high accuracy while minimizing damage to nearby healthy tissues.

SRT may be advised in the following situations:

• Brain Tumors: SRT is used for conditions such as meningiomas, acoustic neuromas, pituitary tumors, and small metastatic or primary brain tumors. It is beneficial when the cancer is close to delicate brain structures.
• Early-Stage Lung Cancer: Patients with small lung nodules or early lung cancer who cannot undergo surgery (due to age, medical conditions, or reduced lung function) often benefit from SBRT.
• Liver Tumors: SRT is suitable for liver tumors or metastases that cannot be removed surgically, primarily when located near major blood vessels or sensitive tissues.
• Spine and Bone Lesions: SRT effectively treats spinal or vertebral tumors while minimizing the risk of damaging the spinal cord and surrounding nerves.
• Prostate Cancer: In selected cases, SRT (SBRT) is used as a short-course, high-precision radiation option for managing localized prostate cancer.
• Recurrent Tumors: SRT can be considered for tumors that return after previous treatments, providing a safe option when traditional radiation cannot be repeated.

SRT is typically chosen when patients need a non-invasive, targeted treatment that offers strong tumor control with minimal recovery time.

How Is Stereotactic Radiotherapy Performed?

Stereotactic Radiotherapy (SRT) is a non-invasive, highly precise treatment delivered in a few carefully planned sessions. The entire process is designed to target the tumor accurately. Treatment is typically completed on an outpatient basis, allowing patients to return home the same day.

• Initial Planning and Imaging: The process begins with detailed imaging such as CT, MRI, or PET-CT scans. These images help the radiation oncology team determine the size, shape, and position of the tumor.
• Treatment Mapping and Positioning: A customized treatment plan is created using 3D computer-aided design (CAD) software. The patient is positioned comfortably using immobilization devices to ensure they remain still during treatment. This positioning is crucial for maintaining millimeter-level accuracy.
• Delivery of Radiation: During each session, multiple focused radiation beams are delivered at the tumor from different angles. The radiation machine (such as CyberKnife, TrueBeam, Gamma Knife, or LINAC) adjusts in real-time to follow the tumor’s position as it moves due to breathing or body shifts.
• Number of Sessions: SRT can be completed in one to five sessions, depending on the type and location of the tumor. Each session typically lasts between 20 and 60 minutes.
• After Treatment: Because it is non-surgical, SRT does not require hospital admission. Most patients receiving SRT can resume normal activities within a day, experiencing minimal side effects. Follow-up imaging is usually recommended after a few weeks or months to assess treatment response.

SRT is widely preferred because it offers strong tumor control, a short treatment schedule, and quick recovery without incisions or prolonged hospital stays.
