Cancers are a group of diseases associated with abnormal growth of cells. Without
any check, the disease may keep on progressing ultimately leading to pre-mature
death. They can arise anywhere in the body and can affect people from all age groups,
socio-economic strata and race. Cancer is the leading cause of morbidity and mortality
in the world. According to data by International Agency for Research on Cancer,
there were 141 lakh new cancer cases, 82 lakh cancer deaths and 326 lakh people
living with cancer in 2012 worldwide. In our own country, about 4.7 lakh new cases
of cancer are detected annually. Cancer is responsible for death of about 3.5 lakh
people annually in India itself.
There are several major types of cancers: carcinomas form in the cells that cover
the skin or line the mouth, throat, lungs and organs; sarcomas are found in the
bones, muscles, fibrous tissues and some organs; leukemia is found in the blood,
the bone marrow, and the spleen; and lymphomas are found in the lymphatic system.
Radiation therapy is the use of ionizing radiation for treatment of diseases and
the specialized field of using ionizing radiation for the treatment of cancers is
known as Radiation Oncology Approximately. 2/3rd of all cancer patients require
radiation therapy as the sole treatment modality or in combination with surgery
or anticancer drugs (Chemotherapy). Radiotherapy plays a very important role in
curing early stage cancer and in relieving symptoms and possibly prolonging life
for patients with advanced cancers.
Our efforts in the department will be to offer optimal radiotherapy and comprehensive
patient care. Optimal & efficient delivery of treatment not only requires the appropriate
infrastructure but also well trained and motivated personnel. The will facilities
offer modern sophisticated, state-of-the-art treatments like 3-D conformal radiotherapy
(3-D CRT), intensity modulated radiotherapy & radiosurgery (IMRT & IMRS), Stereotactic
radiotherapy/ radiosurgery, Image Guided Radiation therapy (IGRT) and Respiratory
Gating apart from conventional radiotherapy. Intra-cranial Stereotactic Radiotherapy
and Radiosurgery are delivered using the "Brain-Lab" system comprising of micro-multileaf
collimator (mMLC) and a dedicated planning system. Apart from the usual features
it has additional features like image fusion using MRI/ PET/ CT images. The PLATO-TPS
is used for both High Dose Rate (HDR) and Low Dose Rate (LDR) Brachytherapy Planning.
Oncentra Planning System is used for Brachytherapy Contouring. A stringent quality
assurance (QA) program and features like the "Online Portal Imaging" ensures efficient
and accurate radiotherapy treatment are also available. With newer Linear Accelerators,
Cone Beam CT and Mega Voltage CT can be done for patients being treated on Trilogy
and Tomotherapy Hi-Art machines.
The current infrastructure will be available for external beam therapy includes
three Linear Accelerators with 6 to 15 MV photon energy and multiple electron energies
from 6 to 20 MeV.
Modern anticancer drugs have helped to mount a major attack against cancer. Many
cancers like blood cancer (leukemias), lymphomas and other childhood cancers which
were uniformly fatal twenty-five years ago can now be completely cured or effectively
contained by these drugs.
A combined treatment using anticancer drugs along with surgery and/or radiotherapy
achieves a greater therapeutic effect. The expert team of medical oncologists at

Chemotherapy (also called chemo) is a type of cancer treatment that uses drugs to
destroy cancer cells. Chemotherapy works by stopping or slowing the growth of cancer
cells, which grow and divide quickly. But it can also harm healthy cells that divide
quickly, such as those that line the mouth and intestines or cause hair to grow.
Damage to healthy cells may cause side effects.
Often, side effects get better or go away after chemotherapy is over. This can be
given before surgery or radiotherapy called neoadjuvant therapy or after called
adjuvant chemotherapy. Chemotherapy may be used to destroy cancer cells that have
come back (recurrent cancer) or spread to other parts of the body (metastatic cancer).
Earlier there used to be less number of chemotherapy drugs but today we have several
options of giving 1st, 2nd and 3rd line drugs. Low dose metronomic chemotherapy
is also showing some promising results and could be used to treat the cancer as
a chronic disease.
