Brain metastases are a rare finding in patients with primary gynecologic malignancies having a poor outcome despite treatment. We sought to use the National Cancer Database (NCDB) to characterize the incidence of brain metastases and types of treatment administered. We queried the NCDB from 2010-16 for patients with endometrial, cervical, and ovarian primaries with brain metastases at diagnosis treated with radiation-whole brain radiation (WBRT) or stereotactic radiosurgery (SRS).

Intensity-modulated radiation therapy (IMRT) has emerged as the standard treatment technique for advanced head and neck cancers, whereas three-dimensional conformal radiotherapy (3D-CRT) has remained standard for early glottic cancers. We used the National Cancer Database (NCDB) to identify predictors of IMRT use and effect on outcome in these patients.

Purpose: This study examined the effects of preoperative incentive spirometry (IS) education (POISE) on postoperative outcomes for knee and hip total joint replacement patients.

Design: In this prospective study, 140 patients were randomized to Group 1 (POISE intervention = 50 completing) or Group 2 (no intervention = 56 completing) (34 dropped).

Methods: The Group 1 intervention consisted of formal instruction preoperatively for IS home use, postoperative use, and IS volumes documentation.
