Perfusion volume correlates, percentage of involution, and clinical efficacy at diverse follow-up survey times after MR-guided focused ultrasound surgery in uterine fibroids: first report in a Mexican mestizo population.

Objectives: To evaluate the clinical efficacy of magnetic resonance-guided focused ultrasound surgery in a Mexican mestizo population.

Methods: This retrospective study included 159 women (mean age 37 ± 6.4 years, range 22-53 years) from 2008 to 2010.

[Principles and technique of magnetic resonance guided focused ultrasound surgery (MRgFUS) in the treatment of uterine fibroids].

Uterine fibroids are a significant source of morbidity for women of reproductive age, and can result in substantial symptoms affecting their quality of life. Definitive treatment has traditionally been a myomectomy, but increasingly women are not prepared to undergo such an invasive procedure for a benign and usually self-limiting condition. Focused ultrasound ablation is one of the least invasive treatment options outside medical therapy and does not require an anesthetic.

Radiofrequency ablation of invasive breast carcinomas: a phase II trial.

Background: Local ablative therapy of breast cancer represents the next frontier in the minimally invasive breast-conservation treatment. We conducted a phase II trial to evaluate radiofrequency ablation (RFA) of invasive breast carcinomas.

Methods: Consecutive patients from two Mexican Institutions with invasive breast cancers < 4 cm, with no multicentric tumors and no previous chemotherapy were included in this trial.

Radioguided occult lesion localization (ROLL) versus wire-guided lumpectomy for non-palpable breast lesions: a randomized prospective evaluation.

Background: It is important to optimize the localization technique for non-palpable breast lesions.

Methods: One hundred consecutive women with non-palpable breast lesions were randomized to radioguided occult lesion localization (ROLL) or wire localization (WL). For ROLL technique (99m)Tc-labeled particles of human serum albumin were injected under breast-imaging control.
