Why do some people not respond to chemo?

Resistance can occur when cancer cells—even a small group of cells within a tumor—contain molecular changes that make them insensitive to a particular drug before treatment even begins. Because cancer cells within the same tumor often have a variety of molecular changes, this so-called intrinsic resistance is common.

How many rounds of chemo can a person have?

During a course of treatment, you usually have around 4 to 8 cycles of treatment. A cycle is the time between one round of treatment until the start of the next. After each round of treatment you have a break, to allow your body to recover.

What is the life expectancy after chemotherapy?

During the 3 decades, the proportion of survivors treated with chemotherapy alone increased from 18% in 1970-1979 to 54% in 1990-1999, and the life expectancy gap in this chemotherapy-alone group decreased from 11.0 years (95% UI, 9.0-13.1 years) to 6.0 years (95% UI, 4.5-7.6 years).

Is chemotherapy the last stage?

What is second line chemotherapy?

Second-line treatment is treatment for a disease or condition after the initial treatment (first-line treatment) has failed, stopped working, or has side effects that aren't tolerated.

What is palliative chemotherapy?

Clarification regarding the term palliative chemotherapy is critical: palliative chemotherapy is defined as chemotherapy that is given in the non-curative setting to optimize symptom control, improve quality of life (QoL) and, ideally, to improve survival.


Does chemo get worse with each cycle?

Each chemo experience is unique. Don't plan your chemo response until you've gone through your first infusion. The effects of chemo are cumulative. They get worse with each cycle.

How long can palliative chemo keep you alive?

The increasing effectiveness and lessened toxicity of palliative chemotherapy is well supported by randomized trial data. First-line chemotherapy for patients with non–small cell lung cancer improves survival by 2 to 3 months, relieves symptoms, and improves quality of life compared with best supportive care.

Does 5 year survival rate mean you have 5 years to live?

The percentage of people in a study or treatment group who are alive five years after they were diagnosed with or started treatment for a disease, such as cancer. The disease may or may not have come back.

  • certain breast cancers, such as inflammatory breast cancer (IBC) and triple-negative breast cancer (TNBC)
  • large B-cell lymphoma.
  • lung cancer.
  • rare prostate cancers such as small-cell carcinomas or lymphomas.


Do all cancers eventually come back?

Does cancer always come back? While cancer doesn't always return, recurrence is common for some hard-to-treat forms of cancer. These recurrences usually follow certain patterns that patients may be aware of in order to catch things as early as possible. There's no way to guarantee that cancer won't return.
