Services

Our 24 x 7 in-hospital specialty services include: 

  • Internal Radiation Therapy (Brachytherapy) 
    Internal Radiation Therapy uses sealed radioactive sources for cancer treatment. The sources can be in the form of needles, wires, seeds, etc. With the availability of HDR (High Dose Rate) brachytherapy, treatment can now be done on an outpatient basis and takes less than an hour. There are two methods of delivery: 
  • IMRT (Intensity Modulated Radiation Therapy) 
    IMRT is a cutting-edge form of radiation therapy that delivers high doses of radiation to localized tumours from multiple angles. Using numerous fine beams with varying intensity, IMRT targets the tumour while minimizing exposure to surrounding healthy tissue, reducing side effects and increasing the chances of eradicating the tumour. 
  • Three-dimensional conformal radiation therapy (3DCRT) 
    The Department of Radiation Oncology utilises advanced technology to achieve successful treatment outcomes. 3D treatment planning allows for better accuracy in targeting tumours and minimizing exposure of normal tissues to radiation.  
  • Intracavitary/Intraluminal Radiation Therapy - the sources are delivered near the tumour through tubes inserted into body cavities and passages. It is commonly used in the treatment of cancer of uterus cervix, vagina, oesophagus trachea and bronchus (wind pipes in the neck and lungs), and gall bladder. 
  •  Interstitial Radiation Therapy - the sources are directly inserted into the tumour. It is used to treat tumours of the head and neck, cervix, breast, limbs, perianal and pelvic regions. 
  • Stereotactic Radiosurgery and Radiotherapy (SRS and SRT) 
     
    Stereotactic radiosurgery is a non-invasive procedure that uses a single high dose of radiation to treat a small target area in the head with high precision. Stereotactic radiation delivered in multiple fractions spread over several days is called stereotactic radiotherapy. The most common conditions treated are: 
    • Arteriovenous/vascular malformations 
    • Trigeminal Neuralgia 
    • Malignant and benign brain tumors 
    • Intracranial metastases 
    • Meningioma 
    • Acoustic tumors 
    • Pituitary tumours 

       
  • Total Body Radiation (TBI) 
     
    Total Body Irradiation (TBI) is a procedure that delivers a dose of radiation to the entire body. It is used for patients undergoing bone marrow or stem cell transplant to destroy any remaining cancer cells and also to suppress the immune system in organ transplant patients to prevent rejection of the donor's cells 
     
  • Total Skin Radiation 
     
    This technique permits the delivery of high doses of radiation to the skin without treatment to the underlying tissues and organs. It is especially useful in the treatment of mycosis fungicides (coetaneous T-cell lymphoma) and other rare lymphomas of the skin.  
  • Strontium Therapy for Ocular Tumors 
     
    The department is equipped with strontium 90 ophthalmic applicator which is used to treat eye tumours (both benign and malignant). This applicator treats other eye conditions like superficial conjunctival tumours. 

Facilities

Linear Accelerators with Multi-leaf collimators and a Si Panel 

The Elekta Precise digital linear accelerators are medical devices used for external beam radiation therapy. They are equipped with advanced features such as triple photon and multiple electron capabilities, 3Dimensional conformal therapy (3D CRT), Intensity Modulated Radio Therapy (IMRT), and Stereotactic Radio Surgery, as well as an amorphous portal imaging system for treatment field verification. 

Stereotactic Radiosurgery and Radiotherapy (SRS and SRT) 
Stereotactic radiosurgery is a non-invasive procedure that uses a single high dose of    radiation to treat a small target area in the head with high precision. Stereotactic radiation delivered in multiple fractions spread over several days is called stereotactic radiotherapy. The most common conditions treated are: 

  • 3D Line ERGO++ treatment planning system is used for Stereotactic Radiosurgery (SRS) and Stereotactic Radiation Therapy (SRT). 
  • The advantage is small tumour can be completely controlled without a major Neuro Surgical Procedure. 
  • SRS Frames help localize the target. 
  • Micro MLC s are used to define the treatment field. 

Nucletron / Micro Selection HDR Brachytherapy 

The Micro Selectron and Plato system from Nucletron, Netherlands, is a high dose rate after loading system for cancer treatment. It uses CT scan images to plan the treatment and delivers a high dose to the tumor while minimizing the dose to surrounding healthy tissue.  

Radiation Oncology Treatment Planning System 

The high-end computer system and software programs used in radiation therapy treatment planning and localization of tumour targets utilises the latest tools and robust dose calculation algorithms to generate precise treatment plans quickly and accurately. This system is critical for the delivery of high-dose radiation therapy.

Dedicated CT Simulator- Siemens / Somatom Emotion 

CT Simulator is a CT scanner with special software and moving laser beams. These CT scans are used to localize the tumor and other critical organs around the tumor. They help to ensure delivery of adequate dose to target volume with minimum possible dose to critical structures. 

Conventional Simulator- Nucletron / Evolution

An X-ray machine called a ‘simulator’ is used to plan and verify treatment ports for radiotherapy treatment.  

Multidisciplinary Tumour Boards 

The multi-disciplinary approach to treating patients with tumours is facilitated by having all relevant departments under one roof. This makes the management of most malignancies easier for both the patient and physician. 

Clinic Day Details 
Leukemia and Lymphoma Tumour Board Monday The doctors from Pathology, Radiation Oncology and Medical Oncology involve in this tumour board and the cases are discussed for management with the best outcome. 
Neuro Oncology Multidisciplinary meeting Tuesday  
A team of neuro surgeons, radiation oncologists and medical oncologists discuss all brain tumour cases. The clinical information and scans and other investigation results are reviewed and the best treatment strategy for each patient is formulated through these combined discussions. 
Urology Tumour Board Alternate Tuesdays Urological cancers are discussed in this tumour board comprising of Urologist, radiation oncologist and medical oncologist and the best treatment strategy is decided for each patient. 
Chest Tumour Board Alternate Tuesdays Lung cancers are discussed in this tumour board comprised of a pulmonologist, cardiothoracic surgeon, radiation oncologist, and medical oncologist and the best treatment strategy is decided for each patient. 
Head and Neck Oncology Multidisciplinary meeting Wednesday A panel of head and neck oncology surgeons, plastic and reconstructive surgeons, radiation oncologists, medical oncologists, and pathologists discuss every head and neck case and the best treatment modality for each patient is decided. 
Breast and Gynaecology Tumour Board Wednesday All breast cancer cases, and gynaecology related cases are discussed by gynaecologists, surgical oncologists, radiation oncologists and medical oncologists. All relevant case records and investigations are reviewed before arriving at the best possible treatment plan. 
GI Tumour Board Thursday All cases of gastrointestinal cancers are discussed by a surgical gastroenterologist, radiation oncologist and a medical oncologist. The optimal sequencing of each modality of treatment for each individual patient is discussed and planned in this meeting.
