The rate of cancer recurrence is determined by many factors, including age, sex, cancer type, treatment duration, stage of advancement, grade of original tumor, and cancer-specific risk factors. [2] [3] [4] If recurrent cancer has already moved to other body parts or has developed chemo-resistance then it may be more aggressive than original ...
Relapse within the first 18 months of diagnosis is considered as functional high-risk multiple myeloma. [81] Depending on the person's condition, the prior treatment modalities used, and the duration of remission, options for relapsed disease include retreatment with the original agent, use of other agents (such as melphalan, cyclophosphamide ...
Biochemical recurrence is a rise in the blood level of prostate-specific antigen (PSA) in prostate cancer patients after treatment with surgery or radiation. Biochemical recurrence may occur in patients who do not have symptoms. It may mean that the cancer has come back. Also called PSA failure and biochemical relapse. [1]
Relapse is a term to describe returning symptoms of the disease after a period of remission. In cancer-treatment, doctors usually avoid the term "cured" and instead prefer the term " no evidence of disease " ( NED ) to refer to a complete remission of cancer, which does not rule out the possibility of relapse.
Minimal residual disease (MRD), also known as Molecular residual disease, is the name given to small numbers of cancer cells that remain in a person either during or after treatment when the patient is in remission (no symptoms or signs of disease). Sensitive molecular tests are either in development or available to test for MRD.
Recurrent event analysis is a branch of survival analysis that analyzes the time until recurrences occur, such as recurrences of traits or diseases. Recurrent events are often analyzed in social sciences and medical studies, for example recurring infections, depressions or cancer recurrences.
Recrudescence is the recurrence of an undesirable condition. In medicine, it is usually defined as the recurrence of symptoms after a period of remission or quiescence, [1] [2] [3] in which sense it can sometimes be synonymous with relapse. In a narrower sense, it can also be such a recurrence with higher severity than before the remission. [3 ...
Response evaluation criteria in solid tumors (RECIST) is a set of published rules that define when tumors in cancer patients improve ("respond"), stay the same ("stabilize"), or worsen ("progress") during treatment.
