Multidisciplinary treatment, mainly chemotherapy combined with immunotherapy, is preferred in patients with advanced lung cancer who are negative for driver genes and have an Eastern Cooperative Oncology Group performance status (ECOG PS) score of 0-1; in contrast, patients with an ECOG PS score of 3-4 should be managed with supportive treatment and palliative care rather than chemotherapy or other antitumor treatments.

What is a good ECOG score?
The ECOG performance status scores also provide prognostic estimates at the lower levels of functioning. A score of 3 on the ECOG scale correlates to a survival of approximately less than 3 months, while a score of 4 correlates to an approximate survival of less than 1 month. 5
What is the ECOG score for asymptomatic status?
aPerformance status was measured by ECOG score as follows: 0, asymptomatic; 1, symptomatic, ambulatory; 2, symptomatic, in bed less than 50% of the time; 3, symptomatic, in bed more than 50% of the time; 4,100% bedridden.
What is the ECOG performance status in clinical trials?
Researchers worldwide take the ECOG Performance Status into consideration when planning trials to study a new treatment method. This numbering scale is one way to define the population of patients to be studied in the trial, so that it can be uniformly reproduced among physicians who enroll patients.
Can performance status scores predict prognosis for lung cancer?
Studies have also demonstrated a high level of agreement across different raters for both scoring systems. 1,3,4 Performance status scores are often used to help determine prognosis for lung cancer. Several studies that used the Karnofsky performance scale have determined that predicting survival is valid only for patients with scores less than 50.
What is ECOG in cancer treatment?
Determines ability of patient to tolerate therapies in serious illness, specifically for chemotherapy, simpler than the Karnofsky Scale. Patients with active cancer under treatment. The ECOG Performance Status is a simple measure of functional status.
What does ECOG 4 mean?
4. Completely disabled; cannot carry out any self-care; totally confined to bed or chair.
What is the importance of ECOG?
ECOG is as independent predictor of the response to chemotherapy, overall survival and progression-free survival in carcinoma of unknown primary site.
What is the use of ECOG and Karnofsky performance status scoring in cancer patients?
Eastern Cooperative Oncology Group (ECOG) and Karnofsky performance status (KPS) scores are commonly used for selection of appropriate patients in clinical trials or for standard cancer treatments. KPS score was first introduced by Karnofsky et al. in 1948 in patients receiving chemotherapy for lung cancer [1].
What are ECOG levels?
It describes a patient's level of functioning in terms of their ability to care for themself, daily activity, and physical ability (walking, working, etc.). Researchers worldwide consider the ECOG Performance Status Scale when planning cancer clinical trials to study new treatments.
What is performance status in oncology?
Patient PS is one of the most central factors in cancer care. 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 is a medical performance status?
General health (performance status) When describing a person's general health, trial protocols usually call it performance status. Doctors use a scale to grade how well you are. There are different versions, but the World Health Organisation (WHO) scale is the most commonly used.
What does ECOG PS stand for?
Abstract. The ECOG Scale of Performance Status (PS) is widely used to quantify the functional status of cancer patients, and is an important factor determining prognosis in a number of malignant conditions.
What does Ecog Acrin stand for?
-ACRIN Cancer Research GroupECOG-ACRIN. ECOG-ACRIN Cancer Research Group is one of the five U.S. network groups of the NCI National Clinical Trials Network (NCTN) Program. ECOG-ACRIN formed from the merger of the Eastern Cooperative Oncology Group (ECOG) and the American College of Radiology Imaging Network (ACRIN).
What is ECOG and Karnofsky?
The Karnofsky's index of performance status (KPS) and the Eastern Cooperative Oncology Group Performance Status Scale (ECOG PS) are widely used methods of assessing the functional status of cancer patients. In this study, we compare their predictive validity, and suggest a table of transformation between scales.
What is a good Karnofsky score?

What is the Karnofsky score?
A standard way of measuring the ability of cancer patients to perform ordinary tasks. The Karnofsky Performance Status scores range from 0 to 100. A higher score means the patient is better able to carry out daily activities.
What is the ECOG performance status?
The ECOG Performance Status and the Karnofsky Performance Status are two widely used methods to assess the functional status of a patient. Both scales have been in the public domain for many years as ways to classify a patient according to their functional impairment, compare the effectiveness of therapies, and assess the prognosis of a patient. The Karnofsky index, between 100 and 0, was introduced in a textbook in 1949.* Key elements of the ECOG scale first appeared in the medical literature in 1960.**
When was the ECOG scale developed?
The scale was developed by the Eastern Cooperative Oncology Group (ECOG), now part of the ECOG-ACRIN Cancer Research Group, and published in 1982. It circulates in the public domain and is therefore available for public use.
What is the meaning of "ecog"?
GRADE. ECOG PERFORMANCE STATUS. 0. Fully active, able to carry on all pre-disease performance without restriction. 1. Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature, e.g., light house work, office work. 2.
How long does it take to live with lung cancer?
Performance status scores are often used to help determine prognosis for lung cancer. Several studies that used the Karnofsky performance scale have determined that predicting survival is valid only for patients with scores less than 50. At scores of 30-40, patients had a survival time of approximately 49.8 days, while patients with scores of 10-20 had survival of approximately 16.8 days. 5
What is the score of a performance status score?
David Karnofsky and his colleagues described the first performance status scoring in a textbook published in 1948. The Karnofsky scale uses a scale between 0 and 100. A score of 100 represents normal activity, and a score of 0 occurs at death. 2
Is Karnofsky score reliable?
Several studies have determined that both the Karnofsky and ECOG performance status scores are reliable. Studies have also demonstrated a high level of agreement across different raters for both scoring systems. 1,3,4
Is there evidence for treatment benefit or harm?
As a result, evidence for treatment benefit or harm has rarely been quantified in patients with poor performance status. Research is needed to evaluate the benefits and harms of chemotherapy use among metastatic cancer patients stratified by performance status.
Does palliative chemotherapy improve QOL?
Although palliative chemotherapy is used to improve QOL for patients with end-stage cancer , its use did not improve QOD for patients with moderate or poor performance status and worsened QOD for patients with good performance status. The QOD in patients with end-stage cancer is not improved, and can be harmed, by chemotherapy use near death, ...
