A better definition of the characteristics of the tumors in terms of progression regarding various parameters, that is, clinical stage, PSA serum value, tumor differentiation, has resulted, despite the heterogeneity of the disease, in the determination of subgroups of tumors with different prognosis, which would lead to an improved therapeutic strategy.
Clinical examination and a CT scan in February 2010, revealed further progression, notably regarding the right cervical adenopathy (2.2 × 1.5 cm) and the right pectoral lesion (8.5 × 4.2 cm).

More research is needed on the true relationship between prognostic factors for symptomatic knee OA progression, especially regarding factors where conflicting, limited or inconclusive evidence was presented.
Overall, syndecan-4 is a versatile molecule regarding tumor progression and more studies on its roles in cell physiology and the changes that accompany an invasive phenotype are needed for further advances in this field.
Death was regarded as a progression event in those subjects who died before disease progression.
Exercising on a Bobath ball is regarded as a progression in training programs to gain control of the spine [ 28], where the aim of the exercise is, through a moveable support, to increase the degree of demand in the stabilization training.
The occurrence of other malignancies and death without progression was regarded as events not related to progression.
Furthermore, an independent prognostic value regarding progression free survival was reported by multivariate analysis[ 13, 16].
Within a standard evolutionary perspective, tumor progression is regarded as intrinsic to the relative fitness of cancer cells based upon stochastic tumor mutations, of which aneuploidy is one variety.
Disease progression was regarded if there was more than 25% increase in the area of enhancement, appearance of a new lesion, or deterioration in the patient's clinical status that was thought to be related to tumor progression.
