Only patients with successful ANC engraftment were evaluated for aGVHD and cGVHD was evaluated only in patients with a minimum follow-up of 100 days. The CI of relapse was calculated from the date of allo-HSCT or the date of getting CR after transplantation until relapse. Nonrelapse mortality (NRM) was defined as death without evidence of disease relapse. GvHD-free, relapse-free survival (GRFS) events were defined according to the original report as the first event among grades III and IV aGvHD, severe cGvHD, relapse, and death [26 (link)]. All statistical tests were two-sided and P value < 0.05 was considered significant. The statistical analyses were performed using IBM SPSS 17.0 statistical software (IBM, North Harbour, Portsmouth, UK).

Data were presented as mean ± standard error of mean unless otherwise indicated. Differences in the continuous quantitative variables of demographics, operative data were analyzed using analysis of variance. Kaplan–Meier estimates of survival were plotted, and survival differences were analyzed using the log-rank test. Univariate and multivariate analyses were used to explore the effects of several prognostic factors by the cox regression proportional hazards model. Differences with two-sided P value <0.05 was considered statistically significant. Statistical analyses were performed using IBM SPSS17.0 statistical software.

Data were presented as mean ± standard error of mean or median for quantitative variables, or as numbers and their frequencies as proportions (%) for categorical variables unless otherwise indicated, which were then compared by Student t tests, analysis of variance or χ² tests according to variable distribution wherever possible. We performed analyses of survival with Kaplan-Meier curves and comparisons among factors using log-rank test. Univariate and multivariate analyses were finally applied to assess the prognostic value of the new WHO 2010 grading classifications and the AJCC seventh staging manual for p-NETs by Cox regression proportional hazards model. Statistics was considered significant when P value of two sides was below 0.05. Statistical analyses were performed by IBM SPSS 17.0 statistical software.
