Significant variables then entered a second stage, grouping variables into abdominal symptoms, other symptoms and investigations.

According to the AJCC 6th edition stage grouping criteria [ 40], 33 cases (14.7%) were stage I-II, and 192 (85.3%) were stage III-IV.
The latter authors concluded that the effects of occupation or income are likely to be intertwined with other household characteristics, primarily life stage grouping [ 42].
The most appropriate age threshold for stage grouping of WDTC is debatable.
The objective of this study was to evaluate the best age threshold for stage grouping by comparing multivariable models designed to evaluate the independent impact of various prognostic factors, including age based stage grouping, on the disease specific survival (DSS) of our population-based cohort.
Muscular vessel invasion (P=0.001), tumor (T) stage by European Neuroendocrine Tumors Society ENETSS) classification (P<0.001), ENETS stage grouping (P<0.001), and stage grouping by the American Joint Committee on Cancer AJCCC stage, P<0.001) were important predictors of disease-specific survival in patients with SPN.
Reflecting these facts, patients with advanced tumor have poor prognosis: Five-year survival rates for stages I, II, and III are 98, 81, and 56%, respectively, according to the tumor, node, and metastasis stage grouping [11].
However, expression was not correlated to parameters such as tumor differentiation or stage grouping.
Also, angptl4 mRNA expression level was not statistically associated with tumor size (p = 0.09), and 2002 AJCC TNM stage grouping (p = 0.17).
As a result stage grouping is also altered.
