What are the performance scales for cancer?
Two primary performance scales are used to measure performance status for those living with cancer: The Eastern Co-operative Oncology Group (ECOG)/WHO system, 4 and the Karnofsky performance score. 5 The first of these ranks performance status on a scale of 0 to 5, and the second on a scale of 0 to 100. Note that these scales differ in whether a lower number or a higher number means better performance status. With the ECOG/WHO performance status, the ideal score zero, whereas with the Karnofsky performance status the ideal number is 100.
What is performance status?
Performance status is a measure of how well a person is able to carry on ordinary daily activities while living with cancer, and provides an estimate of what treatments a person may tolerate. 1 Performance status is most often mentioned in the setting of clinical trials, as many trials are designed for people who have ...
Why is performance status important?
Understanding performance status can help people with cancer and their oncologists weigh the potential benefits and risks of different options. This is even more important now that there are many more treatment choices than in the past.
Why do oncologists ask questions?
These questions are asked as a way to determine how well you are doing with your activities of daily living, or "ADLs." 2 By evaluating these activities your healthcare provider can figure out your "performance status" and this measure of performance status can be helpful in many ways:
What does 0 mean in ECOG?
ECOG/WHO Performance Status. 0: Fully active, no restrictions on activities. A performance status of 0 means no restrictions in the sense that someone is able to do everything they were able to do prior to their diagnosis. 1: Unable to do strenuous activities, but able to carry out light housework and sedentary activities.
What are some myths about clinical trials?
The popular comment about "being a guinea pig" is often said in jest, yet many people do not understand exactly what clinical trials involve or their importance in cancer research. It may help to realize that every cancer treatment available—every drug and every procedure—was once only used in clinical trials, and at that time, the only people who could stand to benefit from these trials were those who participated in the trials.
What is clinical trial selection criteria?
As selection criteria for clinical trials. Many clinical trials require patients to have a good performance status before trying an experimental treatment. To evaluate an individual's response to treatment. 3 . To see if/how the cancer is progressing. To estimate prognosis. 3 .

Is chemo hard on the body?
Doctors don’t prescribe chemo lightly or any other systemic therapy for that matter. The stage of the tumor matters; chemotherapy guidelines almost always specify cancer stage with suggested regimens. The overall physical condition and health of the patient is another big factor as chemo is hard on the body.
What is the scale for asymptomatic cancer?
The most commonly used is typically referred to as the Zubrod or ECOG (Eastern Cooperative Oncology Group) scale. This scale ranges from 0 to 4, with 0 being fully functional and asymptomatic, and 4 being bedridden. The other scale sometimes used is the Karnofsky scale.
What is the role of PS in cancer?
It plays a role both in shaping prognosis and in determining the best treatment for a patient with cancer. Performance status is a score that estimates the patient’s ability to perform certain activities of daily living (ADLs) without the help of others.
What does it mean when a patient has a worse PS?
Patients who have a worse PS and limited functional capacity tend to have more difficulty tolerating rigorous cancer treatments . These patients have less favorable outcomes than more fit patients with better PS, regardless of the treatments given.
What are the factors that affect prognosis?
There are many factors that can predict whether someone is likely to do well or poorly with their disease. Age, the stage of a cancer, and other illnesses all affect prognosis, but PS is one of the most important variables. It is more important than a patient’s actual age in predicting how a patient is likely to do.
Does PS change with cancer?
Patient PS can and usually does change over time. Patients can experience a gradual worsening of their PS as their cancer progresses, both from the cancer itself and from the cumulative adverse effects of treatments. On the other hand, effective treatment can lead to an improvement in PS if a patient is limited by cancer-related symptoms (as opposed to other chronic medical conditions unrelated to cancer) that improve as the cancer responds to treatment.

How long does bladder cancer last?
The 5-year relative survival rate for localized bladder cancer varies by the type of cancer. Around 25% of bladder cancers invade the muscle wall of the bladder. The 5-year relative survival rate is 47% for localized, muscle-invasive bladder cancer, and 81% for localized bladder cancer that is not muscle-invasive.
Why is survival rate important?
However, it is essential to remember that a range of factors influence s survival rates and chemotherapy success rates. Many of these factors vary from person to person.

Why do people need chemotherapy?
Fromme, M.D., MCR, FAAHPM, both of Oregon Health and Science University, wrote, “In reality, only two major reasons exist for administering chemotherapy to most patients with metastatic cancer: to help them live longer and/or to help them live better. In exchange for treatment-related toxic effects (as well as substantial time, expense, and inconvenience), chemotherapy can prolong survival for patients with a variety of -- though not all -- solid tumors. Chemotherapy may also improve quality of life for patients by reducing symptoms caused by a malignancy. In this issue of JAMA Oncology, Prigerson and colleagues report some troubling trial results: chemotherapy administered to patients with cancer near the end of life achieved neither goal.

Does palliative chemo affect quality of life?
For people who were in relatively good health and had better quality of life when the study started, more than half (56%) had worse quality of life in their final week of life after receiving palliative chemotherapy. To compare, 31% of people who had better quality of life when the study started who didn’t receive palliative chemotherapy had worse quality of life in their final week of life. So palliative chemotherapy seemed to decrease quality of life for people who were in relatively good health at the beginning of the study.

How does palliative care improve QOL?
Palliative care is aimed at providing comprehensive support and comfort via a multidisciplinary team approach to enhance QOL when cure is not an option [ 12 ]. Some research has shown that stoppage of intensive medical treatments and providing palliative care have improved both QOL and length of survival of advanced cancer patients [ 13 ]. Further, the incorporation of early specialized palliative care may reduce the risk of receiving CT during the final two weeks of life [ 14 ]. Many patients who have good performance status, however, receive palliative CT as they near end of life with the aim of increasing survival length and even to improve QOL [ 10 ].
What are the factors that affect QOL at the end of life?
Factors that were most associated with lower QOL at end of life included death in intensive care and receipt of life-prolonging therapies [ 2 ]. Better patient QOL was associated with positive relationships with their physician and pastoral spiritual care provision [ 2 ]. Other factors that improved QOL at death included personal religious activities, caregiver health, and better perceived mental health [ 2 ].

Does palliative CT help with cancer?
In a study from Sweden, Nappa and his colleagues (2011) evaluated characteristics associated with use of palliative CT in patients with advanced stage epithelial cancers in the last month of life. Of 374 patients, 87 (23%) received palliative CT in the last month of life [ 24 ]. Use of palliative CT was associated with shorter survival, increased hospital admissions, and less likelihood of dying at home. Further, there was less documented evidence of discussion about ceasing treatment with patients who received palliative CT during the last month of life.
