According to global cancer statistics published in 2024, over 60% of all cancer patients now require radiation treatment at some point during therapy planning. With cancer rates continuing to rise, patients are increasingly seeking treatments that are faster, more precise and associated with fewer side effects. One major answer to this need is the growing field of latest IORT technology, and at the forefront of this advancement is Dr. Mathangi, Senior Radiation Oncologist and In-charge at Gleneagles Cancer Institute, Bangalore. She has not only trained across Germany and Denmark in advanced intraoperative radiation procedures, but also pioneered next-generation clinical adoption in India for multiple tumour categories.
This article explores everything patients must know about modern intraoperative radiation therapy (IORT), why its adoption is accelerating globally, and how Dr. Mathangi’s specialised training and implementation strategies are transforming cancer outcomes in South India and beyond. Her ability to combine clinical wisdom with cutting-edge systems like TrueBeam STx and advanced stereotactic platforms gives patients access to treatments usually available only in elite global centres.
Intraoperative radiation therapy (IORT) is a radiation treatment technique delivered directly to a tumour bed during surgery, while the surgical site remains open. By enabling clinicians to bypass surrounding tissue structures, IORT offers extremely targeted dose delivery that significantly reduces long-term radiation-related complications.
The therapy benefits include:
Patients in Bangalore and across India are increasingly choosing IORT because it combines the precision of surgical removal with real-time radiation application. For cancers such as breast cancer, brain tumours, spine tumours, cervix cancer, prostate cancer and lung cancer, the approach allows immediate microscopic disease control.
IORT delivers a concentrated radiation dose precisely to the tumour bed immediately after surgical excision. This direct approach ensures the cancer cell environment is neutralized before healthy tissues have the chance to shift or regenerate around the area. For tumour types notorious for local recurrence—such as breast, colorectal, esophageal and prostate cancers—this method is a game-changer.
With systems like mobile IORT machines, it is now possible to bring specialised radiation equipment directly into the operating theatre instead of shifting patients to a separate bunker. This development has exponentially expanded treatment access across regions that previously had no physical space for large radiation bunkers.
Patients treated under the care of Dr Mathangi benefit from surgical collaboration models that integrate oncology, medical physics, radiation oncology and precision imaging into a single procedural workflow. This reduces postoperative costs, complications, wound healing delays and treatment anxiety.
TrueBeam STx represents one of the most advanced radiation delivery platforms in global cancer practice. What sets it apart is its ability to integrate imaging, motion verification and beam modulation into one real-time system. Dr Mathangi installed the first TrueBeam STx machine in the entire Asia Pacific region, establishing Bangalore as a reference point for high-end radiation oncology innovation.
Benefits include:
Patients under her care undergoing advanced stereotactic radiation planning experience unparalleled cancer control outcomes and faster recovery timelines. TrueBeam STx complements IORT application by enabling precision radiotherapy before or after surgery if needed.
The integration of mobile IORT machines has reshaped cancer service delivery patterns worldwide by reducing infrastructural reliance. These compact systems can be wheeled from room to room, allowing surgeons and oncologists to deliver radiation exposure directly in the theatre.
This advancement eliminates:
Bangalore’s Gleneagles Cancer Institute, under the direction of Dr Mathangi, is among the few oncology centres bringing global intraoperative machines into Indian oncology practice—bridging gaps between advanced Western medical technologies and local patient needs.
IORT has demonstrated strong results in cancer groups where surgical tumour removal leaves behind microscopic residual risk. Dr Mathangi regularly employs advanced radiation strategies for:
Because IORT delivers radiation at the operative field, it is particularly useful where surgical removal borders vital organs or nerves.
Image guided radiotherapy (IGRT) helps oncologists adjust tumour position imaging in real-time depending on body motion, breathing patterns and tumour shifts during treatment. When used in combination with IORT, the precision output is amplified further.
These techniques allow:
Dr Mathangi’s training from Copenhagen University Hospital in IGRT procedures forms a massive advantage for patients seeking accurate and predictable clinical outcomes.
Few clinicians in India possess the pedigree, case experience and academic background of Dr Mathangi. Her advancement in innovation in oncology is rooted in diverse international research exposure and strong clinical volume.
She has:
Her leadership ensures that Bangalore receives radiation strategies identical to Western oncology benchmarks.
Radiation devices used for intraoperative precision must meet stringent accuracy, safety and integration standards. At Gleneagles Cancer Institute, treatment planning software, onboard imaging detectors, dosimetric verification systems and surgical theatre compatibility frameworks allow seamless radiation delivery during operations.
These technology layers work together to ensure that radiation exposure distributes uniformly across tumour cells without physically affecting skin layers or neighbouring muscle tissue.
Patients who choose IORT under Dr Mathangi experience:
The difference lies not only in machine availability but in clinical judgment, surgical navigation, scientific decision-making and radiation customisation—skills that can only come from decades of hands-on practice.
Those who do not access these therapies early may miss windows of curative control. Every month of surgical delay raises recurrence chances and increases radiotherapy toxicity probability.
