This case study looks at 9 patients who developed cardiac metastases, a tricky situation on which very little data is currently available. We hope that by describing 9 cases, this will provide an easily accessible road map for clinicians around the world when this difficult situation arises. In many cases, the combination of limited ‘palliative’ radiation with immune therapy proved beneficial.
AIM
Merkel cell carcinoma (MCC) is a rare neuroendocrine, cutaneous malignancy with poor prognosis once metastasized. The aim of this study was to conduct a systematic literature review to assess clinical outcomes associated with chemotherapy regimens in metastatic MCC.
MATERIALS & METHODS
Embase®, MEDLINE®, MEDLINE®-In-Process and CENTRAL were searched for studies published in January 2016.
RESULTS & CONCLUSION
Overall, the literature on chemotherapy in patients with metastatic MCC is sparse, with most studies being case series/reports. Across all studies, response rates ranged from 20 to 61%, with higher response rates in first-line setting (53-61%) versus second-line setting (23-45%). Among responders, duration of response was short (≤8 months) in both first- and second-line settings. There is a need for novel agents that can induce durable responses in metastatic MCC.
