There's no single survival percentage for "chemo patients"; it varies immensely by cancer type, stage, patient health, and treatment combinations, but chemotherapy significantly improves outcomes for many, with some cancers seeing 5-year survival rates above 90% (like breast, prostate) and others lower (like lung cancer at ~19%). While chemotherapy is vital and can extend life for many, particularly in early stages or with certain cancers (testicular, Hodgkin's), some studies suggest its overall impact on total adult cancer survival is modest (around 2-3%) compared to other factors.

Based on the overall cohort, that included 905 chemotherapy-exposed vs 3390 chemotherapy-naïve patients, overall survival rates at 18 and 30 months were 76.3 vs 69.3% and 61.6 vs 54.3%, favoring chemotherapy-exposed patients ( Figure 1A ).
You might have physical changes like hair loss, skin changes or new scars, ostomies, weight changes, or loss of limbs. Cancer and treatment might also cause changes to your sex organs, sexual health, fertility, or mental health. Some of the changes may be temporary, while others are permanent.
An individual is considered a cancer survivor from the time of diagnosis through the rest of life.
This is called acquired resistance. In this case, the chemo does its job initially, wiping out the most vulnerable cancer cells. But a few tougher, more resilient cells manage to survive. These survivors then multiply, creating a whole new army of cancer cells that are no longer fazed by the original drug.
Chemotherapy is unlikely to have much of an effect on Stage IV (metastatic) cancers, whereas it can add months or even years to a person's life if they have been diagnosed with Stage I – III cancer.
For most patients, a switch to palliative care that does not include chemotherapy should happen when the performance status is 3 or greater, defined as more than 50% of time in a bed or chair (not bed alone). In our practice, if the patient has difficulty walking to the clinic, it is time to make the transition.
Most cancers that are going to come back will do so in the first 2 years or so after treatment. After 5 years, you are even less likely to get a recurrence. For some types of cancer, after 10 years your doctor might say that you are cured. Some types of cancer can come back many years after they were first diagnosed.
Estimates for loss in expectation of life vary widely by age at diagnosis for all cancers except for melanoma and breast cancer. For example, those who were diagnosed at the age of 50 with lung cancer lose nearly 30 years of remaining life, whereas patients above 80 years of age lose <10 years.
Which types of cancer are more likely to come back?
Can chemo brain affect personality? Some studies suggest chemo brain can contribute to depression, frustration or irritability. This can make everyday tasks feel harder than they used to. It's normal to feel discouraged, but recognizing these changes can help you find effective coping strategies.
Signs of improvement can show up early in chemotherapy. These signs include tumor shrinkage on scans, lowered tumor marker levels in blood tests, and better blood counts. Healthline says these signs help doctors see if treatment is working.
86% of patients alive at 3 months completed the Decision Regret Scale. Results combined the 2 top categories indicating the greatest extent of regret. By this criterion, 13% of patients (95% CI: 7.4% - 19.2%) expressed regret at the 3-month timepoint after starting chemotherapy.
If there's a high likelihood that chemotherapy may get rid of your cancer, that benefit may outweigh possible side effects. Some patients say they actually feel better and have more energy soon after starting chemotherapy because the symptoms of their cancer regress.
You'll need follow-up care to watch for a recurrence or secondary cancers. If chemotherapy marks the end of your cancer treatment, the next step is to map out when and how often you'll need to be monitored for a recurrence or secondary cancer. This may involve scans, blood tests, and regular in-person check-ups.
Patients who died under palliative care service had longer median survival (120 days) after last chemotherapy as compared to other patients [120 and 43 days respectively, P < 0.001, Figure 2].
The Median Duration of Response tells you how long your cancer can be expected to respond to the chemotherapy, before the cancer starts growing again. For most cancers where palliative chemotherapy is used, this number ranges from 3-12 months. The longer the response, the longer you can expect to live.
Brain and pancreatic cancers have much lower median survival rates which have not improved as dramatically over the last forty years. Indeed, pancreatic cancer has one of the worst survival rates of all cancers. Small cell lung cancer has a five-year survival rate of 4% according to Cancer Centers of America's Website.
Approximately 80% of patients living with metastatic cancer will die of their diagnosed cancer, while 20% will die of competing causes (heart disease, COPD, stroke, subsequent cancer deaths in >50% of these patients). This has remained consistent for 30 years.
The 62-day rule for cancer, primarily in the UK's NHS system, is a key waiting time target: patients who receive an urgent referral for suspected cancer should begin their first cancer treatment within 62 days from the date the hospital gets that referral. It's part of broader standards that also include a 28-day "Faster Diagnosis" goal (diagnosis or ruling out cancer within 28 days of urgent referral) and a 31-day "Decision to Treat" standard (treatment within 31 days of the agreed-upon plan).
Key Takeaways. Some cancers can spread during chemotherapy because the drugs might not work or cancer cells develop resistance.
Your oncologist takes information about cancer survival rates into account when thinking about your prognosis. But they consider much more than data: They consider everything that they know about you, from the type of cancer that you have and the cancer stage to your age and overall health.
A study that evaluated the quality of life of 140 cancer patients who had refused, discontinued, or completed chemotherapy revealed that the quality of life of patients who refused or discontinued chemotherapy was no different than that of patients who completed treatment [10].
Age was of less importance, with patients aged 70–79 years versus those aged ≥80 years. Treatment of elderly NSCLC patients with chemotherapy is feasible if they have a good PS and appears to prolong survival. In this study, we found no significant differences in survival either between age groups or genders.
“Hydration is important, even before you start chemo.” “Always remember, chemo is our weapon, not our enemy.” “Find your breasties—they're a wonderful bunch. Drink lots of water, rest when needed, and try to get out for walks when you can.
