Purpose: Advancements in breast radiation therapy offer innumerable benefits to patients and the health care system. Despite promising outcomes, clinicians remain hesitant about long-term side effects and disease control with accelerated partial breast radiation therapy (APBI). Herein, we review the long-term outcomes of patients with early-stage breast cancer treated with adjuvant stereotactic partial breast irradiation (SAPBI). Methods and Materials: This retrospective study examined outcomes of patients who received diagnoses of early-stage breast cancer treated with adjuvant robotic SAPBI. All patients were eligible for standard ABPI and underwent lumpectomy, followed by fiducial placement in preparation for SAPBI. Using fiducial and respiratory tracking to maintain a precise dose distribution throughout the course of treatment, patients received 30 Gy in 5 fractions on consecutive days. Follow-up occurred at routine intervals to evaluate disease control, toxicity, and cosmesis. Toxicity and cosmesis were characterized using the Common Terminology Criteria for Adverse Events version 5.0 and Harvard Cosmesis Scale, respectively.
Result(s): Patients (N = 50) were a median age of 68.5 years at the time of treatment. The median tumor size was 7.2 mm, 60% had an invasive cell type, and 90% were estrogen receptor positive, progesterone receptor positive, or both. Patients (n = 49) were followed for a median of 4.68 years for disease control and 1.25 years for cosmesis and toxicity. One patient experienced local recurrence, 1 patient experienced grade 3+ late toxicity, and 44 patients demonstrated excellent cosmesis.
Conclusion(s): To our knowledge, this is the largest retrospective analysis with the longest follow-up time for disease control among patients with early breast cancer treated with robotic SAPBI. With follow-up time for cosmesis and toxicity comparable to that of previous studies, results of the present cohort advance our understanding of the excellent disease control, excellent cosmesis, and limited toxicity that can be achieved by treating select patients with early-stage breast cancer with robotic SAPBI.

A case of tracheal injury after emergent endotracheal intubation: a review of the literature and causalities [Case Report]

Chen, E H; Logman, Z M; Glass, P S; Bilfinger, T V
IMPLICATIONS/CONCLUSIONS:Tracheal lacerations are rare, but potentially fatal, complications of intubations. Diagnosis of such conditions is difficult, and thus a high level of suspicion must be kept. We present a case and review the literature for factors that indicate high-risk patients.
