In this blog post, we will focus on learning more about how to understand a patient's disease reaction once it has started. Another significant topic to explore will be how well and how long a person survives after the commencement of the disease, says the colon cancer doctor in Kolkata.

Factors that determine prognosis and life expectancy

As with most malignancies, the prognosis and life expectancy are determined by:

·         Cancer detection stage — Localized stage 0 tumours have a better prognosis than distant stage three or four malignancies. The earlier cancer is detected, the better the prognosis and the longer the life expectancy.

·         Cancer Grade – The higher the grade, the greater the difference between normal and cancer-like cells, and the worse the prognosis.

·         Lymph nodes involvement – Cancer spreads through the lymphatic system. The prognosis becomes poorer as the number of lymph nodes implicated increases.

·         The older you are, the worse your prognosis will be.

·         Size and location of tumour – If the tumour is located or sized in such a way that it blocks the colon or causes a hole in the colon, both of these things can have a negative impact on the prognosis.

·         Individual health — The better the patient's health, the more likely they are to endure cancer therapy and emerge cancer-free.

·         Carcinoembryonic antigen (CEA) – It is a blood-borne protein molecule. When a patient has colon cancer, their blood CEA levels may rise, affecting their response to treatment.

The average age of disease onset in colon cancer patients was discovered to be about 49.1 years in a study undertaken by an Indian establishment over the course of a year. According to the best cancer doctor in Kolkata all prognosis-related numbers in India differ from those in the West, including a patient's nutritional state.

Even at the same age, each person's prognosis is different.

The percentage of people who live after being diagnosed with colon cancer is referred to as survival rates. The percentage of people living after five years of disease detection is known as the five-year survival rate. The relative survival rate is the rate of survival compared to a healthy person of the same age who does not have the disease.

 

Location-based survival rates

Colon cancer that is identified at stage 0 and well captured in the organ of origin is known as localised colon cancer. Such colon cancers have a 90 percent five-year relative survival rate.

Colon cancer that has spread to another section of the body is known as regional colon cancer (stage 2 and 3). Such colon cancers have a known five-year relative survival rate of 71%.

The one that has spread to another section of the body is called distant (stage 4). As per the colon cancer treatment specialist in Kolkata, such colon tumours have a known five-year relative survival rate of 14%.

India has one of the lowest five-year survival rates for colorectal cancer in the world, at less than 40%.
