Imaging in Cardio-Oncology: Where Are We and Where Should We Be Going?

Rationale and proposed framework for shared decision making in cardio-oncology

Physicians have a duty to present diagnostic and therapeutic choices with rational guidance that respects patient values and realizes patient goals. In cardio-oncology, we commonly encounter patients who understandably feel overwhelmed or feel that they have no favorable options, particularly in the context of advanced malignancy. Accordingly, a longitudinal multidisciplinary commitment to shared decision making (SDM) ensures that physicians and patients actively participate in this process to promote the best possible outcomes from the patient perspective. We propose a practical framework for approaching these difficult decisions in cardio-oncology drawing upon our experience in clinical practice.

Sarcoma of the Heart Treated with Stereotactic MR-Guided Online Adaptive Radiation Therapy

We present the first case in the literature of a patient with a histology-proven intimal sarcoma of the heart, recurrent after surgery, treated with stereotactic MR-guided online adaptive radiation therapy on an MR-Linac machine. The treatment was feasible and well tolerated. The CT scan 6 months after the last treatment showed stable disease.

Risk Profiling of Cancer Treatment-Related Cardiovascular Disorders in Breast Cancer Patients Who Received Adjuvant Chemotherapy With Trastuzumab

Background: The prognosis of cancer survivors has dramatically improved, but effective strategies for cancer treatment-related cardiovascular disorders (CTRCD) remain to be elucidated in the emerging field of cardio-oncology. In this study, we investigated risk factors for CTRCD in breast cancer patients treated with trastuzumab. Methods and Results: We performed a retrospective analysis of 141 consecutive women who received adjuvant trastuzumab, and underwent baseline (BL) and follow-up (FU) echocardiography at Juntendo University between April 2010 and December 2016. The major concomitant treatment was anthracyclines in 94% and radiotherapy in 53%. During the median treatment period of 11 months, there were 22 (15.6%) cardiology consultations, 3 (2.1%) treatment interruptions with irreversible CTRCD, and no deaths. Left ventricular ejection fraction (LVEF) was decreased from a median 67.5% (BL) to 63.4% (FU; P<0.0001), with reduced LVEF noted in 26.2% at FU<90%BL, in 13.5% at FU Collapse
