Cancer survival rates

What is the cancer survival rate?

Cancer survival rate or survival statistics tell you the percentage of people who survive a certain type of cancer during a specific period of time. Cancer statistics often use an overall survival rate of five years.

The cancer survival rate is usually expressed in percentages. For example, the overall 5-year survival rate for bladder cancer is 77 percent. That means that of all the people who have bladder cancer, 77 out of 100 live five years after diagnosis. In contrast, 23 out of 100 die within five years of being diagnosed with bladder cancer.

Cancer survival rates are founded on research information calm on hundreds or thousands of people with specific cancer. An overall survival rate includes people of all ages and health conditions who have been diagnosed with their cancer, including those diagnosed too early and those diagnosed too late.

Your physician may be able to provide you with more specific statistics based on the stage of cancer. For example, 56 percentages, or just over half, of people diagnosed with early-stage lung cancer live at least five years after diagnosis. The five-year survival rate for people diagnosed with advanced-stage lung cancer that has spread (metastasized) to other areas of the body is 5 percent.

Overall survival rates do not specify whether cancer survivors are still in treatment at five years or whether they no longer have cancer (achieved remission). Other types of cancer survival rates that provide more specific information include:

  • Disease-free survival rate. This is the number of people who have no indication of cancer after treatment.
  • Progression-free survival rate. This is the number of people who have been treated for cancer and have no signs of cancer recurrence or who have cancer that has been stable without growing.

Cancer survival rates regularly use a five-year survival rate. That does not mean that cancer cannot come back after five years. Certain cancers can come back many years after they are first found and treated. For some cancers, if it hasn’t come back five years after the initial diagnosis, the chance that it will come back later is very small. Deliberately increase the risk of cancer coming back with your doctor.

How are cancer survival rates used?

You and your doctor can use cancer survival statistics to:

  • Understand your forecast. The experience of other people in the same situation can give you and your doctor an idea of ​​your prognosis – the chance that your cancer will be cured. Other factors include age and general health. Your doctor uses these factors to help her understand the severity of your condition.
  • Develop a treatment plan. Statistics can also show how people with the same type and stage of cancer respond to treatment. You can use this information, along with your treatment goals, to weigh the pros and cons of each treatment option.

For example, if two treatments give you similar chances of remission, but one has more side effects, you can choose the option with the fewest side effects.

In another example, a treatment may offer a chance for a cure, but only for 1 or 2 people out of 100. For some, these chances are promising enough to withstand the side effects. For others, the possibility of a cure does not outweigh the side effects of treatment.

Your physician can help you recognize the benefits and risks of each treatment.

Cancer survival rates in India is amongst the lowest in the world

The study by an international team of physicians followed cancer patients from 67 countries, including India, between 1995 and 2009. It was recently published in The Lancet medical journal.

The number of people who survive five years after being diagnosed with cancers of the digestive system appears to be particularly low in India compared to more advanced countries. Survival rates are only 19% for stomach cancer compared to 25-30% in most countries, and 58% survive in South Korea. In India, the colon cancer survival rate is 37%, while in most countries it is 50% to 59% and reaches 65% in the US. Only 4% of patients with liver cancer survive for five years in India compared to 10-20% elsewhere. Survival rates have been reduced for rectal cancer in India.

Even in breast and prostate cancers, where medical early payment has ensured that more than 80% of patients survive in advanced countries, only about 60% of Indian patients survive. Survival rates for ovarian cancer have decreased in India from 23% in 1995-99 to 14% in 2005-09. Cervical cancer survival rates are 46% compared to the global figure of 50%, but there is a slight decrease in India from 47% in 2005.

Michael Coleman, a lecturer at the London School of Hygiene and Tropical Medicine, and one of the study’s lead authors, told TOI that one of the explanations for the low survival rates in India could be that equitable access is not yet available. to early diagnosis and optimal treatment. for all the people of India.

Coleman said that out of 27 population-based cancer registries in India, only four participated in the study. These represent approximately 59 lakh population, which is approximately 0.5% of the population of India in 2009. However, this is not a small population sample and accurately represents the trajectory of cancer incidence and survival in these regions.

The study highlights a troubling question: Is India losing the fight against cancer? Coleman says Indian politicians should reflect on whether enough is being done for India’s growing number of cancer patients. It also emphasizes the importance of cancer registries because only then can a valid picture of the disease emerge.

“The total rate of the entire cancer registration process per listed patient, including the staff and equipment for data collection, analysis, and reporting, is probably less than the cost of a single chest X-ray. One thing is very clear: without cancer registries that are politically supported, operationally stable, and adequately funded and staffed to publish good data on a regular basis, any politician trying to make rational cancer rule is simply flying blind,” he claimed.

Poor and good cancer survivals  among the male population of northeast India

The Northeast region of India has an overall high incidence, mortality, and lowest cancer survival rate in the country; Cancer is expected to be diagnosed annually in this region of about 40,000 people a year. The cancer death rate in Northeast India is increasing mainly due to difficulties in accessing facilities for cancer diagnosis and treatment, socio-economic conditions, lack of awareness, taboo, misconceptions, and wide difference in both cancer diagnosis and treatment among the eight different states (regions) within Northeast India. Also, the affordability of cancer care remains a major challenge in this part of India for effective cancer control.

Objective: This study was conducted with the vision to provide insight into the cancer survival pattern of 45 million people living in the Northeast region of India with correlation with time in diagnosis and treatment competence status. Methods: All registered cases with a history of cancer between calendar years 2010-2014. The observed five-year survival was calculated based on the entire follow-up until 2017.

Three categories were made for the analysis of survival by treatment, 1) those who completed cancer treatment 2) those who did not complete treatment 3) those who did not take any targeted cancer treatment. The 5-year survival rates were generated using SPSS V19 software. The Kaplan-Meier method was used to generate the statistics. Results: The overall 5-year survival for all cancers in men is 24.3%, with an earlier stage at diagnosis and better survival (stage I, 52.1%) than at the later stage (stage IV, 18.8%) at the time of diagnosis. The full course of targeted cancer treatment was found to play an important role in improving the survival of patients.

Five-year survival for complete cancer-targeted therapy is 27.5%, followed by 12.5% ​​for incomplete therapy, and 8.5% for those without a cancer-targeted therapy group. The disparity in survival was seen between different cancer sites, as some cancers harm younger persons more than others. The 5-year survival observed for all sites ranged from 0% to 75.8%. Cancer of the liver (0%), pancreas (0%), lung (2.4%), gallbladder (7.9%), and stomach (10.3%) is considered more lethal than other cancers since Five-year survival was in the range of 0% -10%. Hodgkin lymphoma cancer (75.8%) has the highest five-year cancer survival rate, followed by testis (60.1%), male breast cancer (55.3%), penis (49, 7%), and skin cancer (49.1%).

The rate of prostate cancer (19.0%) is very low associated with other parts of the world where it reaches around 100% in many countries. Advances in early detection and treatment can improve cancer survival rates in these regions. Conclusion: The 5-year cancer survival showed an increase in survival with a decrease in stage at diagnosis and a decrease in the percentage decrease in the number of treatments among the Northeast population.
