Distant metastases limited to the liver occur in 15-20% of all patients initially diagnosed with colorectal cancer [ 10- 12].
In the beginning of 2012, the British Columbia large retrospective series reinforced the importance of treating the primary with the most favourable survival rates observed in subsets of patients with young age, good performance status, ER-positive disease, distant disease limited to one site, bone-only involvement, or fewer than five metastatic lesions [ 122].
However, activity for distant control was limited, with a distant metastasis rate of 29.7%.
The logistical challenges of placing skilled instructors at these distant sites limit the global dissemination of the latest best practices in patient care, and strategies are needed to expand the impact of high-quality instructors, advances in medical knowledge, and new technologies.
In fact, Bulinus populations investigated in the present study originated from geographically distant countries, limiting gene flow between them.
Patients harbouring limited distant metastases in addition to their locally advanced disease at diagnosis (n = 24) were eligible for response assessment but omitted from the RFS and DSS analysis.
Twenty-four (T3/T4) patients had limited distant metastases (Table 1); these patients were included in the response analysis but omitted from the relapse-free (RFS) and disease-specific survival (DSS) analysis.
Again, this assay has been validated in many different patient subgroups, and the prediction of (distant) recurrence was limited to 5 years after diagnosis.
For example, some workers gave out appointments for dates in the very distant future, or limited the maximum number of patients seen per day.
If distant lesions were limited to soft tissue, MST was 20 months, although it was shorter for patients with pulmonary involvement (14 months, P=0.002 in log-rank test) or other visceral lesions (7 months; P<0.001; Figure 1A).
Since sexual species of apomictic complexes are usually self-sterile (Dickinson et al., 2007; Hörandl, 2009 b ), their ability to found populations in geographically distant areas is limited by the need of mating partners and pollinators.
