The covariates were primary tumour characteristics (T, N and hormone receptor status) and patient characteristics at recurrence (menopause, performance status and age).
The treatment of locoregional recurrent tumors can be challenging, since many factors should be included such as histology type, stage of tumor, metastatic disease status, previous treatment, the interval time between primary treatment and locoregional recurrence, and performance status.
The average scores for patients' ages were calculated using a t-test, and the clinicopathological items, such as sex, location, local recurrence, and performance of FS, were studied using Fisher's exact test.
Follow-up of these patients until 2005 provided information concerning recurrence rate and performance state.
Published data indicate an emerging role for mp-MRI in the depiction of locoregional recurrence, while the performance of PET/CT still remains unclear.
Because the studied populations in our meta-analysis comprised patients who had both local and distant recurrence, the diagnostic performance of CT can be influenced by the fact that local recurrence detection is difficult with CT (Fig. 6).
The studies had similar eligibility criteria: histologically or cytologically unresectable pancreatic cancer, within 8 weeks of diagnosis or disease recurrence and Karnofsky performance status of ⩾50% (BB128) or ⩾60% (BB193).
FDG-PET/CT demonsuperiorsuperior diagnostic performance for recurrence in lymph nodes whilst recurrences in the skeleton and liver are more reliably depicted by MRI (Fig. 1).
Although a little rusty after his recent hamstring problem, no sign of a recurrence and reasonably assured performance.
It was designed in 3,880 m2 contribution area based on 10 years recurrence interval and the performance in peak flow reduction was up to 60%%.
It is also shown that, in PBWE, minimum cost design can be guided by assigning same target reliability, but different mean recurrence intervals for different performance levels.
