Adenoid cystic carcinoma is a rare cancer that arises from secretory glands. Metastases are mainly seen in the lungs and bones. Cardiac metastases are extremely rare; only 1 case has previously been described. In this patient, cardiac metastases were suspected based on CT imaging. Tumor imaging by Ga-prostate-specific membrane antigen (PSMA)-11 PET is mainly used in prostate cancer patients but is also of interest in adenoid cystic carcinoma patients because of high PSMA-ligand uptake in salivary glands. Ga-PSMA-11 PET imaging supported the suspicion of cardiac metastases, because the cardiac lesions showed similar tracer uptake compared with other metastases.

Article Synopsis
  • Mammary carcinoma consists of different cell types with varying abilities to spread, and a specific type of cell (4T1) was identified as highly metastatic, influenced by TGF-β and BMP-1.
  • Researchers found that inhibiting BMP-1 not only reduced cancer cell growth but also improved the effectiveness of the chemotherapy drug doxorubicin.
  • This study highlights the potential of targeting BMP-1 as a promising therapeutic strategy for treating aggressive metastatic breast cancer.

Cardiac metastases are the most frequent cardiac tumors. They can cause dysrhythmia, myocardial dysfunction, pericardial effusion, and heart failure. In decreasing order, the major primary malignancies associated with cardiac metastases are pleural mesothelioma, lung adenocarcinoma, undifferentiated carcinomas, lung squamous cell carcinoma, and breast carcinoma.

The field of cardio-oncology has traditionally focused on the impact of cancer and its therapies on cardiovascular health. Mounting clinical and preclinical evidence, however, indicates that the reverse may also be true: cardiovascular disease can itself influence tumor growth and metastasis. Numerous epidemiological studies have reported that individuals with prevalent cardiovascular disease have an increased incidence of cancer.
