Re-evaluation of 6th edition of AJCC staging system for nasopharyngeal carcinoma and proposed improvement based on magnetic resonance imaging.
To use magnetic resonance imaging to re-evaluate and improve the 6th edition of the International Union Against Cancer/American Joint Committee on Cancer staging system for nasopharyngeal carcinoma. ⋯ Using the 6th American Joint Committee on Cancer staging system produces an acceptable distribution of patient numbers and segregation of survival curves among the different stage groups. The prognostic accuracy of the staging system could be improved by recategorizing the T, N, and group stage criteria.

There is no correlation between erectile dysfunction and dose to penile bulb and neurovascular bundles following real-time low-dose-rate prostate brachytherapy.
We evaluated the relationship between the onset of erectile dysfunction and dose to the penile bulb and neurovascular bundles (NVBs) after real-time ultrasound-guided prostate brachytherapy. ⋯ Penile bulb doses are low after real-time ultrasound-guided prostate brachytherapy. We found no correlation between dose to either the penile bulb or NVBs and the development of postimplantation impotency.

Comparison of biochemical relapse-free survival between primary Gleason score 3 and primary Gleason score 4 for biopsy Gleason score 7 prostate cancer.
To determine whether the primary grade (PG) of biopsy Gleason score (GS) 7 prostate cancer (CaP) was predictive for biochemical relapse-free survival (bRFS). Most of the present data regarding the PG of GS7 CaP refer to surgical specimens. Our goal was to determine whether the biopsy GS used at the time of medical decision making predicted for the biochemical outcome. ⋯ Biopsy GS7 PG4 CaP carries a worse bRFS than biopsy GS7 PG3 CaP.

Multicenter StudyHealth-related quality of life in cervical cancer survivors: a population-based survey.
In a population-based sample of cervical cancer survivors, health-related quality of life (HRQoL) was assessed 2-10 years postdiagnosis. ⋯ Most cervical cancer survivors were coping well, although their mental health was worse than in the reference population. Even after 2-10 years, radiotherapy was associated with an increased frequency of treatment-related side effects.

Tolerance and acceptance results of a palladium-103 permanent breast seed implant Phase I/II study.
To test, in a prospective Phase I/II trial, a partial breast irradiation technique using a 103Pd permanent breast seed implant (PBSI) realized in a single 1-h procedure under sedation and local freezing. ⋯ The feasibility, safety, and tolerability of PBSI compares favorably with that of external beam and other partial breast irradiation techniques.
