Complete response to treatment (CR) is the term used for the absence of all detectable cancer after your treatment is complete. Complete response doesn't necessarily mean that you are cured, but it is the best result that can be reported. It means the cancerous tumor is now gone and there is no evidence of disease.

The addition of anti-PD-L1, anti-PD-1 or anti-CTLA-4 checkpoint inhibitors to a single dose of the Triplet improved complete response rates over either mRNA or antibody treatment alone.
What is partial response?
Partial response (PR) – Monoclonal IgM protein is detectable, equal to or greater than 50% but less than 90% reduction in serum IgM level from baseline, reduction in the size of enlarged lymph nodes and enlarged spleen if present at baseline, no new signs or symptoms of active disease.
What is the term for the period after treatment for WM?
The period after treatment when a WM patient has experienced either stabilization of disease, an improvement in disease status, or even, unfortunately, disease progression is called a “response”. While an improvement in disease status is sometimes commonly referred to as a “remission”, the preferred scientific terminology is “response”.

What are the three categories of response criteria?
These are divided into three categories: strong, intermediate, and weak endpoints. See the Levels of Evidence page and individual page's response criteria sections for more details.
What is a weak surrogate endpoint?
The most frequently reported weak surrogate endpoint in non-randomized trials is the objective response rate (ORR), usually using the RECIST criteria . Note that many of these weak surrogate endpoints have been correlated with survival endpoints, with the general maxim being patients who respond to therapy are more likely to achieve remission, remain in remission, and therefore have a longer cancer-specific and overall survival. Regardless, we annotate RCTs by their stated primary endpoint, unless the primary endpoint is positive AND a stronger secondary endpoint has a statistically significant finding.
What is the response to treatment?
Response to treatment supposes that the therapeutic targets that have been defined a priori - either symptoms or a syndrome - have been significantly modified by treatment . If rating scales are used, it is generally accepted that a change of less than 50% in the initial score is significant. Changes below that threshold will be considered as cases of nonresponse or insufficient response. Insufficient response or nonresponse does not always reflect the lack of efficacy of the drug treatment that was chosen; it may be caused by other factors, including the patient's constitution, concomitant somatic illness, pharmacogenetics (fast or slow drug metabolism), or environment (food or drug interactions).
What is considered nonresponse to treatment?
Overall, nonresponse to treatment can be considered if the patient's objective condition and subjective experience do not evolve favorably after a therapeutic trial that was coherent with Axis I and Axis II diagnoses, provided adequate pharmacological doses were used, initial physical disorders were controlled, and detrimental extraneous influences were eliminated.
What is the significance of a placebo response?
The existence of a placebo response leads to the adoption of strict criteria for genuine response, hence the requirement of a 50% improvement in rating scale scores. Placebo response is linked to the patient's emotional ties with the treatment, the clinician's charisma, or the nursing care in hospital. Placebo response wears off or is less significant when the disorder is protracted, severe, or chronic.

What is response assessment?
In daily practice, response assessment is combined with other indicators of the patient's condition to contribute to the decision-making process. In clinical trials, it is widely used to identify and quantify the anti-tumour activity of new agents.
Can oncologists assess biological response?
Over the next decade, oncologists will be able to assess the biological response before the clinical response, and a lot of work and energy will have to be dedicated to assess the predictive and, possibly, the prognostic value of the biological response with regard to the clinical response, as well as more definitive measures of clinical benefit.
Is clinical response an indicator of therapeutic efficacy?
Clinical response is also used as an indicator of therapeutic efficacy in combination with other indicators. Its value as a surrogate indicator of a survival benefit remains unclear in most instances and can hardly be established within the framework of a single randomised trial.
