Does the benefit of sentinel node frozen section vary between patients with invasive duct, invasive lobular, and favorable histologic subtypes of breast cancer?
For patients with ID and IL cancers, the overall sensitivity of FS is>50%, but the yield of FS is<10% for individuals>or =60 years of age with T1a/b tumors. Intraoperative FS may not be worthwhile for this low-yield subset, especially for patients with invasive breast cancer of favorable type.
The intraocular silicone implant as an alternative long-term treatment of chronic ocular hypotony might offer a new option for clinical ophthalmological practice. In vivo studies need to be performed to collect more data on the implant's long-term mechanical and optical properties, as well as long-term biocompatibility.
