Phase 1 clinical trial of stereotactic body radiation therapy concomitant with neoadjuvant chemotherapy for breast cancer.

Purpose: Stereotactic body radiation therapy (SBRT) allows stereotactic irradiation of thoracic tumors. It may have a real impact on patients who may not otherwise qualify for breast-conserving surgery. We conducted a phase 1 trial that tested 5 dose levels of SBRT concomitant with neoadjuvant chemotherapy (NACT) before to surgery.

Second conservative treatment for ipsilateral breast cancer recurrence using high-dose rate interstitial brachytherapy: preliminary clinical results and evaluation of patient satisfaction.

Purpose: To assess early clinical results and evaluate patient satisfaction in case of second conservative treatment (2nd CT) combining lumpectomy plus high-dose rate (HDR) interstitial brachytherapy for patients (pts) presenting with ipsilateral breast cancer recurrence (IBCR).

Methods And Materials: From June 2005 to July 2009, 42 pts presenting with an IBCR underwent a second lumpectomy with intraoperative implantation of plastic tubes in the tumor bed. After performing the dose distribution analysis on the postimplant CT scan, a total dose of 34 Gy in 10 fractions over 5 consecutive days was delivered.

Robotic stereotactic radioablation concomitant with neo-adjuvant chemotherapy for breast tumors.

Purpose: Robotic stereotactic radioablation (RSR) allows stereotactic irradiation of thoracic tumors; however, it has never been used for breast tumors and may have a real potential. We conducted a Phase I study, including neoadjuvant chemotherapy (NACT), a two-level dose-escalation study (6.5 Gy x 3 fractions and 7.

[Purple urine bag syndrome: a case report].

The authors report a case of dark purple urine in a woman with bowel obstruction and bilateral percutaneous nephrostomy urinary diversion for 30 years. This colour was due to the presence of high urinary concentrations of 3-indoxyl sulphate due to the enzymatic activity of Providencia rettgeri. A favourable course was observed in response to antibiotics.

Partial breast irradiation as second conservative treatment for local breast cancer recurrence.

Purpose: Mastectomy is the treatment of reference for local relapse after breast cancer (BC). The aim of this study was to document the feasibility and the results of associating lumpectomy with partial breast irradiation by interstitial brachytherapy (IB) as local treatment for an isolated ipsilateral BC local recurrence (LR).

Methods And Materials: Between 1975 and 1996 at Marseille and Nice Cancer Institutes, 4026 patients received lumpectomy and radiotherapy (RT) (50-80 Gy) for a localized breast cancer of which 473 presented a LR.
