For • Disease-free [or relapse-free] survival (DFS) – example, if both randomisations are done at the this is a standard outcome measure in trials time of study entry with a planned intent to of adjuvant therapy for solid tumours, but in treat analysis, then the inevitable (and antici- AML trials, DFS refers to the survival time pated) large patient drop-out can substantially spent free of disease. Thus, DFS is applicable complicate evaluation of the second therapeutic only to patients who achieve a CR. Since patients OUTCOME MEASURES who fail to achieve a CR are excluded, this measure is unsuitable as an overall assessment There are various choices for outcome measures of therapy. However, it is useful for compar- in clinical trials involving AML patients. The ing two or more post-remission therapies as primary ones are: long as it is recognised that the distribution of DFS is not representative of the result to be • Response rate – the proportion of patients who expected for all patients. This measure suffers from the same are sometimes included in Phase II trials where problems as DFS and, in addition, the usual 146 TEXTBOOK OF CLINICAL TRIALS Kaplan–Meier estimation is no longer valid which treats other risks as independent censoring (see discussion below on competing risks). One way to • Overall survival (OS) – the time from the start properly account for the dependence is through of study to death is an obviously critical out- the use of the cumulative incidence curve, a come measure for any generally fatal disease topic that has been extensively explored in recent like AML in older adults. However, there STATISTICAL MODELS are often difficulties in interpretation, partic- ularly if multiple therapies are given, or if Statistical models are heavily used in AML patients cross over to the alternative therapy trials. Nevertheless, the importance of DFS, OS) are often handled non-parametrically overall survival is so fundamental that it should in the primary analysis (e.

A couple of days after surgery order 30mg nimotop amex, patients are allowed to leave The laminae are then cut at the midline with a diamond bed without wearing a collar. When a patient complains of burr and bone grafts from the spinous processes or ilium neck pain, a collar is recommended until the patient can are shaped to fit the spaces. If a patient does not feel pain, a gentle ac- quired, a long bone block is positioned to connect the de- tive ROM exercise of the neck is recommended. A ceramic spacer can also be sub- weeks after surgery, isometric neck muscle exercises are stituted for an autogenous bone graft [5, 10, 22]. When spinal fusion is required, immobilization of the neck with the collar should last until consolidation of the graft is confirmed roentgenographically.
