Partial Breast Reirradiation for Patients With Ipsilateral Breast Tumor Recurrence After Initial Treatment With Breast Conservation for Early Stage Breast Cancer.

Purpose: Accelerated partial breast irradiation (APBI), including intraoperative radiation therapy (IORT), is an evidence-based treatment option in patients undergoing breast conserving surgery (BCS) for early-stage breast cancer. However, literature regarding reirradiation for patients with ipsilateral breast tumor recurrences (IBTR) is limited. This prospective study assessed the feasibility and efficacy of using APBI in patients who had prior whole breast irradiation.

Emerging radiation techniques for early-stage breast cancer after breast-conserving surgery.

Standard whole-breast irradiation consisting of a dose of 45-50 Gy over 5 weeks with or without the addition of a boost to the tumor bed has equivalent survival to mastectomy and is considered to be the standard of care for most patients with early-stage breast cancer. Newer techniques have been developed to shorten the course of radiation or limit normal tissue exposure in an attempt to increase accessibility to and tolerance of radiation therapy. This article will review some of the newer regimens and techniques for treating early-stage breast cancer after breast-conserving surgery.

A phase II study of radiotherapy and concurrent paclitaxel chemotherapy in breast-conserving treatment for node-positive breast cancer.

Purpose: Administering adjuvant chemotherapy before breast radiotherapy decreases the risk of systemic recurrence, but delays in radiotherapy could yield higher local failure. We assessed the feasibility and efficacy of placing radiotherapy earlier in the breast-conserving treatment course for lymph node-positive breast cancer.

Methods And Materials: Between June 2000 and December 2004, 44 women with node-positive Stage II and III breast cancer were entered into this trial.
