NEOADJUVANT THERAPY IN INDIA

neoadjuvant-therapy-treatmentNeoadjuvant Therapy refers to the administration of therapeutic agents prior to the main treatment. e.g. neo adjuvant hormone therapy prior to radical radiotherapy for adenocarcinoma of the prostate. The aim is to reduce the size or extent of the cancer before employing radical treatment intervention, thus making procedures easier and more likely to be successful, and reducing the consequences of a more extensive treatment technique that would have to be done if the tumor wasn’t reduced in size or extent.

This systemic therapy (chemotherapy, immunotherapy or hormone therapy) or radiation therapy is commonly used in cancers that are locally advanced – where an operation is technically planned at a later stage. The use of such therapy can effectively reduce the difficulty and morbidity of more extensive procedures.

The use of therapy is to turn the tumour from untreatable to treatable by shrinking the volume down. Often it can be unclear which surrounding structures are directly involved in the disease and which are just showing signs of inflammation. By administering therapy a distinction can often be made. Some doctors give the therapy in the hope that a response will be seen so that they can then decide what is the best course of action. Unfortunately not everyone is suitable for therapy in this way as it can be extremely toxic. In some cases reactions are so severe that further treatments, especially surgery are precluded as the patient is rendered unfit for anaesthetic.

Common tumors that use this concept:

  • Breast Cancer
  • Colorectal Cancer
  • Lung Cancer

Neoadjuvant Therapy

Refers to a therapy that is given before the primary treatment in the hopes of making the treatment more effective. In the case of prostate, neoadjuvant hormone therapy, is commonly given to patients with enlarged prostate glands in order to decrease the organ’s volume. Prostate cancer treatments are generally most effective to those with small prostate glands. A large prostate gland may cause complications during the prostatectomy or cause the surrounding organs to be damaged during external beam radiation therapy. An enlarged gland could also cause the prostate to be ineffectively treated during cryotherapy or brachytherapy.
