Disease Failure Rate Within Radiation Fields
Defined as disease that recurs in the initially involved nodal region within the field of irradiation. The disease failure rate within the radiation fields will be estimated with a 95% confidence interval using appropriate methods (e.g., estimate cumulative incidence in the presence of competing risks).
Local and Distant Failure for Children Treated With Tailored-field Radiation
The cumulative incidence of local and distant failure will be estimated. Effect of competing risks will be taken into account. Local failure is defined as in-field, and distant failure is defined as out-of-field.
Prognostic Factors for Treatment Failure: Age
Age was examined for the association with event-free survival (EFS) which was defined as the interval between date on study and date of relapse/disease progression, second malignant tumor, death, or last contact, whichever came first. Given only 11 events, the investigators used univariate Cox model with Score test to compute the p value for the statistical significance.

Toxicities With Grade >1
Comparison of the toxicities of intermediate risk patients treated with Stanford V chemotherapy low dose tailored-field radiation (current HOD05 protocol) to those patients on HOD99 (NCT00145600). Grading of toxicities for HOD05 and HOD99 used the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 3.0.
Prognostic Factors for Treatment Failure: Gender
Event-free survival (EFS) was calculated for the 80 eligible patients. EFS was defined as the interval between on study to relapse, second malignant tumor, or last contact (all alive) whichever came first. For those who had multiple relapses, the first one was counted. Given only 11 events, we examined individually age, gender, histology and stage for its association with EFS using Cox model. P values from Score test were computed for the statistical significance.
Prognostic Factors for Treatment Failure: Histology
Event-free survival (EFS) was calculated for the 80 eligible patients. EFS was defined as the interval between on study to relapse, second malignant tumor, or last contact (all alive) whichever came first. For those who had multiple relapses, the first one was counted. Given only 11 events, we examined individually age, gender, histology and stage for its association with EFS using Cox model. P values from Score test were computed for the statistical significance.
Prognostic Factors for Treatment Failure: Stage
Ann Arbor staging classification was used to stage all patients. Stage was examined (I/II versus III) for the association with event-free survival (EFS), defined as the interval between date on study and of relapse/disease progression, second malignancy, death, or last contact, whichever came first. Given only 11 events, the investigators used univariate Cox model with Score test to compute the p value for the statistical significance. Stage <III showed a better outcome but was not statistically significant.
