Several small pilot studies demonstrated low relapse rates in the range of 3 5% using 1 2 courses of carboplatin (Oliver and Ong, 1996; Krege et al, 1997; Dieckmann et al, 2000).
Mp-MRI after RP is currently indicated to detect small locoregional relapse and also to discriminate between residual glandular healthy tissue, fibrotic tissue, granulation tissue, and nodule recurrence.
However, bone grafting patients with smaller tumors relapsed more often compared to the cement group, which further suggests that bone cement is an effective adjuvant to treat GCT of the long bone, even for larger tumors.
For ER positive vs. negative, grade 1&2 vs. grade 3, grade 1 vs. 2, tumor size large vs. small, and relapse vs. non-relapse Support Vector Machine (SVM) based classifiers were trained and accuracy on out-of-bag samples were established.
Cross-sectional imaging modalities (ultrasound, computed tomography, and morphologic MRI) have previously been evaluated in the detection of local recurrence following RP, but each of them is poorly sensitive for detecting a small-sized relapse and is unable to distinguish between local recurrence and postsurgical scarring [ 50– 50].
The worse association for overall survival in our study is not surprising, since the number of death events is smaller compared to relapse events and several further factors may influence the length of the time period between relapse and death.
Patients with Luminal A subtype generally have the most favorable outcome and have a smaller chance of relapse when treated early [ 78, 79].
The worse association for overall survival is not surprising, since (i) the number of death events is smaller compared to relapse events (Table 1) and (ii) several further factors like differences in the treatment of relapsed disease may influence the length of the time period between relapse and death.In a next step DFS and MFS time as well as OS time were visualized by Kaplan-Meier plots.
Conversely, tumours with a slow growth, typically with a low level of inflammation and a small risk of early relapse, could have a smaller benefit of NSAIDs.
However, clinical examination detected a smaller proportion of relapses in these studies than in the mastectomy studies, with less than one-third of relapses detected this way.
