Relative survival of patients with thyroid cancer by period of diagnosis. Included in the evaluation are 7,95 cases diagnosed between 1988 and 215. The survival results of the SEER program (Surveillance, Epidemiology, and End Results) of the American National Cancer Institute (NCI) are summarized as the period of diagnosis from 2 to 214, and are represented by colored diamonds in order to facilitate comparisons between MCR and SEER. The presented survival curves are derived from clinical records with valid follow-up informations, which means that death certificate cases (DCO) cases are omitted from the analysis. With this one restriction, the MCR has provided populationbased statistics since 1998, collecting data on all cancer cases in the region of southern Bavaria. Historical data of previous time periods can be heavily selected, therefore, univariate survival comparisons of the presented time periods must be carefully considered. Nonetheless, all calculable survival curves are depicted to facilitate the comparison of long time follow-up analyses of relative survival between particular cancers.

Conditional relative 5-year survival of patients with thyroid cancer by extent of disease for period 1988-215 (N=6,899). Conditional relative survival rates refer to the relative survival probability, in this case for 5 years after cancer diagnosis, compared to the age- and sex-matched population (= %) under the condition of being alive for a certain time period (x-axis in Figure 4e). The results illustrate to what extent the cancer induced mortality of particular subgroups declines in the subsequent years after detection of the malignancy. For instance, according to the presented survival statistics, patients in the subgroup extent of disease= Local, who are alive at least 3 years after cancer diagnosis, the conditional relative 5-year survival rate is.% (n=4,182).

Observed post-progression survival of 567 patients with thyroid cancer diagnosed between 1998 and 215. These 567 patients with documented progression events during their course of disease represent 9.2 % of the totally 6,132 evaluated cases (incl. M1, n=25, 4.1 %). Patients with cancer relapse documented via death certificates only were excluded (n=4, 1.7 %). Multiple progression types on different sites are included in the evaluation even when not occuring synchronously. The NOS (not otherwise specified) class is included under the condition, that it is the one and only progression type during the course of disease. Medical record documentation often lacks the linguistic severity to distinguish between local relapse, regional lymph node metastasis and distant spread in solid cancers. Frequently, the statement not specified is the only information in registries regarding relapse of the disease. The category Any type denotes all cases who suffered from at least one relapse during the course of disease (incl. primary M1-status). Although, the real number of relapsed patients is likely to be much higher. The accumulated percentage of patients with local relapse or distant metastasis exceeds the % value because patients are potientially considered in more than one subgroup.
