Randomized Controlled Trial Multicenter Study
Impact of axillary dissection in women with invasive breast cancer who do not fit the Z0011 ACOSOG trial because of three or more metastatic sentinel lymph nodes.
The objective of this study was to determine the effects of axillary lymph node dissection (ALND) versus sentinel lymph node biopsy alone (SLNB) on the survival of patients with 3 or more metastatic lymph nodes (MLN) in invasive breast cancer. ⋯ In conclusion, patients with a T1-T2 invasive breast cancer and at least 3 MLN do not benefit from ALND after SLNB for specific and overall survival, thus limiting ALND to a staging procedure. A subgroup of patients with 3 MLN had a better SS with ALND, possibly due to an under-staging of the SLNB-alone group.

Multicenter Study Comparative Study
Effect of preoperative treatment strategies on the outcome of patients with clinical T3, non-metastasized rectal cancer: A comparison between Dutch and Canadian expert centers.
High-dose-rate brachytherapy (HDRBT) appears to be associated with less treatment-related toxicity compared with external beam radiotherapy in patients with rectal cancer. The present study compared the effect of preoperative treatment strategies on overall survival, cancer-specific deaths, and local recurrences between a Dutch and Canadian expert center with different preoperative treatment strategies. ⋯ We did not detect statistically significant differences in overall survival between a Dutch and Canadian expert center with different treatment strategies. This finding needs to be further investigated in a randomized controlled trial.
