Oncologist decodes cancer staging and its role in treatment: How it’s done and why it’s critical

From stage 0 to stage IV, here’s why cancer staging is essential for determining treatment, explained the oncologist.

Cancer staging is the process of determining what stage the cancer is in; this helps in guiding treatment decisions and predict prognosis. In an interview with HT Lifestyle, Dr Pushpinder Gulia, director, surgical oncology and robotic surgery, CK Birla Hospital, Gurugram said, “First step in any cancer management is establishing a diagnosis which is usually done with a biopsy. Second step is step is staging of the disease which helps the patient to make informed decision and oncologist to select the most appropriate treatment approach and prognosticate the disease.”

What is cancer staging?

“Staging of any cancer indicates the size and its relation to adjacent structures, involvement of lymph nodes or involvement of distant organs. Staging is a complex procedure which includes examination by the treating oncologist, biopsy of the lesion, Radiological investigations like (USG, CT, MRI, PET/CT) and sometimes endoscopies and laparoscopy to delineate the extent of the cancer and it is a blueprint for treatment decision making and prognostic,” the oncologist explained.

How is cancer stage determined?

Dr Pushpinder Gulia said that TNM staging is one of the most common staging systems that offers a standardised system for evaluation of the disease and followed worldwide.

• T (Tumour, T0-T4): Size of the tumour and involvement of surrounding structures
• N (Node, N0-N3): Surrounding lymph nodes involved or not
• M (Metastasis, M0- M1): Spread to distant organs

“Stages are arranged from stage 0 (precancerous) to Stage IV (Metastatic), depending upon the various permutations and arrangements of all the three factors,” the doctor added.

How cancer staging helps treatment:

• Standardised system of evaluation.
• Clinical decision making by treating oncologist, about the type and intent of the treatment.
• Informed decision can be taken by patient and relatives.
• Actual treatment planning and individualised approach.
• Prognostication of the disease.
• Staging is a dynamic process as it keeps on adding the changes depending upon the trials, diagnostic and technological advancements.
