Patient-led advocacy in ALK-positive lung cancer.

Patient-led advocacy organizations in the anaplastic lymphoma kinase (ALK)-positive lung cancer space are becoming increasingly influential. ALK Positive Inc. (hereafter "ALK Positive") is probably the most widely known among these organizations.

New equations for matching a low neck field to oblique upper neck fields with collimator rotation in a 3-field monoisocentric setup for head-and-neck cancers.

With a monoisocentric 3-field technique for treating head-and-neck cancer, collimator rotation may be needed for the upper lateral fields to avoid cephalad-positioned shoulders or to avoid unnecessary arytenoid irradiation while maintaining more anterior coverage. For patients with unilateral lymphadenopathy, lateral oblique-opposed boost fields can be used to encompass the primary tumor and ipsilateral lymph nodes without junctioning through gross disease. When initial collimated lateral fields are also rotated with a gantry angle to produce oblique boost fields, however, the resulting matchline with a low anterior neck (LAN) boost field is no longer nondivergent.

Mitomycin C eliminates the short-term intraocular pressure rise found following Molteno tube implantation.

Purpose: Molteno implants remain popular for treating recalcitrant glaucomas. This study aimed to assess the effect of mitomycin C (MMC) use with Molteno tube implantation upon intraocular pressure (IOP) control and complication rates. In particular, the study aimed to assess any change that MMC might have upon the postoperative hypertensive phase.
