Prophylactic irradiation of retropharyngeal lymph nodes with IMRT or IGRT provides effective regional control for individuals at risk for recurrence in these nodes.
The test later classified her as low risk for recurrence.
† Relative risk for recurrence = 1.
However, in some situations (scenario B),the results from the CR model should be interpreted with caution since the CR model may show that the experimental group is non-inferior to the control for local recurrence, but at the expense of increased distant recurrence or death, which are clinically worse outcomes.
This is reflected in population distribution, spread, control, and recurrence.
For gene signatures obtained from a two-class comparison, the short name generally takes the form of "case vs. control", such as recurrence group vs. recurrence-free group, tumor vs. non-tumor, and tumor vs. normal liver.
The commentary shows that by adhering to the principles developed for the analysis of studies of the efficacy of screening for the presence of a given cancer in persons with no history of this disease, a case-control study of screening for recurrence will improve its chances of obtaining valid findings.
In addition, in a randomised control trial, radiotherapy conferred significantly smaller improvements in recurrence control for patients with ER-negative tumours than for patients with ER-positive tumours [ 42].
The frequency of gains (Additional file 3 S3andand losses (Additional file 3 S3B) along the length of each chromosome was plotted for each analysis group (control group, local recurrence group, distant recurrence group, and local & distant recurrence group).
