Is it possible to refine the indication for sentinel node biopsy in high-risk ductal carcinoma in situ?
The relevance of SNB positivity cannot be overlooked in high-risk DCIS patients, however, because SNB is not free from morbidity and cost, more studies are needed to refine its final indication.
Patients with large creatinine increases (> or = 50%) after CABG surgery have a higher 90-day mortality compared with patients with small increases. Efforts to identify patients with impaired renal function and to preserve renal function before cardiac surgery may yield benefits for patients in the future.
