Eye tumors can be benign or malignant. They can affect any part of the eye. Malignant tumors can arise primarily in the eye or orbit or can manifest as secondaries from a pre-existing malignancy elsewhere in the body. The malignant tumors can affect any age group. The common tumors are Retinoblastoma, Lymphomas, Lacrimal Gland cancer, Melanomas, Optic Pathway gliomas etc.

Dr. Kakkar has been fortunate enough to work under Dr VA Reddy, Director Apollo Cancer Hospitals, Hyderabad who started Ocular Oncology department in association with LV Prasad Eye Institute Hyderabad in 2001 and has pioneered the field of Ocular Oncology. In his six years association, the doctor got exposure to a variety of common and rare eye tumors, participated in the Ocular Oncology multidisciplinary discussions and was very closely involved in the radiation planning and treatment delivery of ocular tumors under guidance of Dr Vijayanand Reddy.

A brain tumor is an abnormal, uncontrolled growth of cells in the brain. Brain tumors can be benign i.e. non-cancerous, which grows slowly like pituitary adenoma, meningioma, acoustic neuroma etc and malignant which are high grade, aggressive tumors with high risk of relapse like malignant gliomas etc. The management of brain tumors involve surgery, radiotherapy, chemotherapy and medical decompression including steroids.

Dr. Sajal Kakkar has a rich experience of treating both malignant and non-malignant brain tumors. He has been trained in various aspects of Neurooncology at prestigious Tata Memorial Hospital Mumbai, Institut Gustave Roussy France, a pioneering cancer centre in Europe and participated in Ist BrainLab Academy for Stereotactic Radiosurgery (SRS) in Hong Kong.

During his stint at Apollo Cancer Hospitals, Hyderabad, Dr. Kakkar was fortunate enough to work on Novalis Tx linear accelerator with SRS/SRT capabilities and one of its kind to be introduced in our country in 2010. He was actively involved in the radiosurgery program there, has many years of experience treating brain tumors like Acoustic Neuroma, AVM, Meningioma, brain metastases etc with SRS and has presented the data in several national and international forums. He has particular interest in treating high grade tumors like Glioblastomas (GBM), Medulloblastoma and brain metastases.

Breast cancer is one of the commonest malignancies diagnosed in Indian females. It can occur in both men and women, but it’s far more common in women. Lump/thickening in the breast is the usual presentation, though changes in the size, shape of the breast or changes in overlying skin are other common presenting symptoms.

Dr. Kakkar gained immense experience in various aspects of breast radiotherapy and brachytherapy at prestigious Tata Memorial Hospital, Mumbai and during his fellowship at Institut Gustave Roussy France, a leading comprehensive cancer centre in Europe.

He is well versed in conventional and advanced radiotherapy planning and delivery techniques as well as motion management strategies in breast cancer radiotherapy. During his stint at Apollo Cancer Hospitals, Hyderabad, he along with Dr VA Reddy (Director) worked on ‘Hypofractionation ’in breast radiotherapy, where overall treatment duration is shortened by three weeks with similar results as traditional long course radiotherapy. Dr. Kakkar has presented this work in major international forums too.

Head and Neck cancers (HNC) broadly include malignant tumors of oral cavity, nasopharynx, tonsil, larynx and pharynx. They are one of the commonest cancers in our country owing to the excessive use of tobacco. These tumors generally present in advanced stage in India because of ignorance, fear of the disease and expenses involved in the overall treatment.

Dr. Sajal Kakkar underwent rigorous training in management of Head and Neck cancers during his training at Tata Memorial Hospital, Mumbai. He also worked as UICC Fellow under his mentor Dr. Avraham Eisbruch, who is a doyen of Head and Neck Cancer radiotherapy, at prestigious University of Michigan, Ann Arbor USA and learned the finer aspects of head and neck cancer radiotherapy.

Dr. Kakkar is well versed in various aspects of high precision radiotherapy like Intensity Modulated Radiotherapy (IMRT), Image Guided Radiotherapy (IGRT) and Rapid Arc (VMAT) to deliver high dose to the target and to save the adjacent critical structures at same time, hence to reduce long term radiation sequelae. He has a particular interest in salivary gland sparing and dysphagia related structures sparing IMRT to improve the quality of life of the patients who undergo radiotherapy for head and neck cancers. HNC management being a successful example of team work, he is associated with a highly qualified and dedicated team of Surgical Oncologist, Medical Oncologist, Radiologist and Oncopathologist.

Prostate cancer is one of the leading cancers to be diagnosed in elderly males in our country. It’s one of the few cancers where an effective screening tool i.e. Serum PSA is available for early diagnosis. Still the patients present in advanced stages as the symptoms of this cancer is similar to age related prostate enlargement and continue to receive the symptomatic treatment for a long time. Hence timely consultation with an Urologist or Oncologist is imperative to catch this disease in early stages. The management involves Observation or Active Surveillance in Early Prostate cancer to Surgery or Radiotherapy with or without Hormone manipulation in early and advanced prostate cancer.

External Beam Radiotherapy planning and treatment delivery underwent lot of innovations since last decade especially in prostate cancer. As prostate is sandwiched between urinary bladder and rectum, it’s critical to deliver tumoricidal doses to the tumor and save the adjacent normal tissues from early and delayed radiation induced toxicities. Dr. Kakkar has a rich experience of treating such tumors by high precision radiotherapy techniques like Intensity Modulated Radiotherapy (IMRT), Image Guided Radiotherapy (IGRT) and Rapid Arc (VMAT), which helps in reducing long term side effects of prostate radiotherapy. He is well versed with another innovation i.e. ‘Hypofractionated Radiotherapy’ where the overall treatment duration is shortened and the dose delivered per day is increased.

The doctor also underwent training in prostate cancer radiotherapy/brachytherapy at prestigious Institut Gustav Roussy, Villejuif, France, where pioneering work is being done in this field.
