Radiation Oncology

The department of Radiation Oncology at MMHRC has been in existence for over two decades, and deals with cancer patients who require Radiation Therapy for their treatment. Almost 70% of the cancer patients require radiation as a part of their treatment. Patients are managed only after incisive discussions with the tumour board which comprises of surgical oncologists, medical oncologists, pathology oncologists and radiation oncologists. The statistics are alarming:

  • By 2010 the number of newly diagnosed cancer patients has risen to eight million in developing countries as compared to five million patients in the developed countries.
  • The crude incidence rate of cancer in India is 44 to 96 per 1,00,000 of the population.
  •  A global comparison shows that India has a high incidence rate of cancers of the uterine cervix & head and neck.
  • The etiology of malignancy is multifactorial ranging from diet, life style genetics, radiation, chemicals etc. cancer is considered to be the final result of interplay of several factors or stimulus. It is likely that there has been a shift in the etiological factors and mechanism of carcinogenesis due to change in life styles with time.
  • The last two decades have witnessed considerable advances in the treatment of cancer, with cure now being a realistic therapeutic objective in over 50% of newly diagnosed patients.

This is where the department of Radiation Oncology, MMHRC, plays a vital role in managing, treating and curing cancers. Radiation Oncology is non-invasive, fast and accurate, often performed as an out-patient procedure. Our department adheres to international standards of quality with top of the line equipment, quality facilities backed by an experienced team of doctors.

Facilities & Equipment

Radiation therapy has been extraordinarily exciting in the past few years. Development in confirming the high dose radiation to the tumour with advanced techniques for planning plus evidence supporting the integration of cytotoxic chemotherapy and hormones with radiation therapy are widely available. The availability and potential use of molecular therapeutics are also on the horizon. Most of the cancers are tackled only in a multimodal approach.

The department is equipped with:

  • Mould Room
    To make the Immobilizing device, which helps in administering precise treatment. These Immobilizers are made for each patient.
  • Telecobalt-60
    The Theratron Phoenix Cobalt unit produces stable, dischromatic beam for treatment of tumours.

  • Linear Accelerator
    The Linear Accelerator has the advantage of greater penetration with reduced side effects, because of its higher beam energy and sharper beam characteristics.
The equipment also offers greater flexibility in treatment delivery option. This is possible because it provides the necessary clearance to perform a wider range of relative gantry (table position). It also has the capability of delivering photon energy at increased adjustable dose rates while lowering the dose to the skin. It is useful for treating all types of tumours.

Advantages:

  • Very high energy beams can be created with a machine that is not very bulky or cumbersome to use.
  • The edges of the beams are sharply defined, allowing additional precision in dose delivery.
  • Electron beams can be created with high energy LINACS. This is of particular value in treating superficial lesions.
  • The dose rate per minute is variable and can be increased to a high degree. This allows the patient to be located at a substantial distance from the machine. It’s also possible to create large fields for total body irradiation while maintaining adequate dose rate.

HDR Brachytherapy (Microselectron)

The department offers HDR Brachytherapy, which is a method of delivering radiation to tumours by placing radioactive sources either within or immediately adjacent to the tumour tissue. Because the radiation source is very close to the tumour, radiation can go directly to the tumour without travelling through normal tissue. Brachytherapy can be given by low dose rate or high dose rate techniques, depending on the length of time the radioactive sources remain in place.

At MMHRC, the brachytherapy team includes a radiation oncologist, physicist, and an Oncology trained nurse. Our excellent staff members work together to provide the best care possible. We offer High Dose Rate (HDR) Brachytherapy for a variety of sites including head and neck, oesophagus, breast, gynaecological and other soft tissue tumours.

Progress

The year 2010 – 2011 has been a remarkable year for this Department in two aspects.

  • We have procured a Linear Accelerator Equipment with the provision for upgradability to three dimensional conformal Radiation Therapy (3D – CRT) and Intensity Modulated Radiation Therapy (IMRT) and Image Guided Radiation Therapy (IGRT).It has the advantages of greater penetration with less amount of undesirable side effects, because of higher beam energy and sharp beam characteristics.
  • Research Activities (Clinical Trials): As a leading Research Institution, MMHRC is a part of many clinical trials which are conducted across the globe. Research activities are being taken up in a big way and the numbers of clinical trials in this department are increasing steadily. There are several advantages of these clinical trials, the most important one being, that newer drugs are available for the unfortunate patients suffering with recurrent cancer, even before they are available in the market. These facilities were available earlier only in western countries, but today MMHRC is not far behind.
