Advantages of intraoperative implant for interstitial brachytherapy for accelerated partial breast irradiation either frail patients with early-stage disease or in locally recurrent breast cancer.

Purpose: To describe the intraoperative multicatheter implantation technique for accelerated partial breast irradiation (APBI) delivered with high-dose-rate brachytherapy (HDR-BT). Secondarily, to evaluate outcomes and toxicity in a series of 83 patients treated with this technique at our institution.

Material And Methods: Retrospective analysis of a series of patients treated with HDR-BT APBI after intraoperative multicatheter interstitial implant between November 2006 and June 2017 at our institution.

Exeresis and brachytherapy as salvage treatment for local recurrence after conservative treatment for breast cancer: results of a ten-year pilot study.

Purpose: To analyze the long-term results of a pilot study assessing excision and brachytherapy as salvage treatment for local recurrence after conservative treatment of breast cancer.

Methods And Materials: Between December 1990 and March 2001, 36 patients with breast-only recurrence less than 3 cm in diameter after conservative treatment for Stage I or II breast carcinoma were treated with local excision followed by high-dose rate brachytherapy implants (30 Gy in 12 fractions over a period of 5 days). No patient was lost to follow-up.

[Comparative study of sentinel node biopsy in patients with multifocal breast carcinoma versus in those with unifocal breast carcinoma.].

Objective: To evaluate the results for sentinel node biopsy (SNB) in patients with multifocal breast cancer (MBC) in comparison to in those with unifocal breast cancer (UBC).

Patients And Methods: A total of 1535 prospective SNB (174 on patients with MBC) were performed at 9 hospitals. In most patients, Tc-99m albumin colloids were injected intraparenchymally into each tumoral focus for SNB.
