Plaque erosion was a predictable clinical entity distinct from plaque rupture in STEMI patients, and gender-specific role of risk factors in plaque erosion should be considered.
Rationale:
Breast cancer is a common malignant tumor. The most common metastatic sites of breast cancer are the bone, brain, liver and lung, and gastrointestinal metastases are rare. Considering that the median time interval from the initial breast cancer diagnosis to stomach metastasis is 77.5 months, gastrointestinal metastases are rarely observed 10 years after primary breast cancer.
Patient concerns:
Here, we present a 63-year-old female with unusual endoscopy results that revealed scattered polyps and mucosal infiltration throughout the stomach, which were later confirmed to be metastatic lobular carcinoma of the breast that had been surgically removed 10 years earlier.
Diagnosis:
The patient was diagnosed with gastric metastases of breast cancer by immunohistochemistry.
Interventions:
The patient underwent endocrine therapy with palbociclib and tamoxifen.
Outcomes:
After 1 year of endocrine therapy, the symptoms of upper abdominal discomfort and fatigue were relieved and a new gastroscopy revealed there had been no significant progression of the gastric metastasis. According to the Response Evaluation Criteria in Solid Tumors (RECIST), the patient reached a state of stable disease.
Lessons:
Gastric metastases of breast cancer are rare in the clinical setting. However, considering the possibility of gastric metastases from breast cancer and performing an upper endoscopy are crucial for patients who present with any subtle gastric symptoms and have a past medical history of breast cancer, even if the breast cancer occurred more than 10 years ago.
BackgroundRaised hemoglobinA1c (HbA1c) is an indicator of pre-diabetes, which is associated with increased risk of coronary artery disease. However, the detailed morphological characteristics of non-culprit plaques in acute coronary syndrome (ACS) patients remain largely unknown.MethodsA total of 305 non-culprit plaques from 216 ACS patients were analyzed by intravascular optical coherence tomography. These patients were divided into three groups according to the serum glycosylated hemoglobin level: normal HbA1c (< 5.7%), pre-diabetes with raised HbA1c (5.7–6.4%) and diabetes mellitus (DM).ResultsPlaques in patients with raised HbA1c had a longer lipid length (17.0 ± 8.3 mm vs. 13.9 ± 7.2 mm, P = 0.004) and greater lipid index (2775.0 ± 1694.0 mm° vs. 1592.1 ± 981.2 mm°, P = 0.001) than those with normal HbA1c but were similar to DM. The prevalence of calcification in patients with raised HbA1c was significantly higher (38.7% vs. 26.3%, P = 0.048) than normal HbA1c but was similar to DM. The percentage of macrophage infiltration in the DM group was higher than that in the normal HbA1c group (20.5% vs. 7.4%, P = 0.005).ConclusionsCompared to patients with normal HbA1c, the non-culprit plaques in ACS patients with raised HbA1c had more typical vulnerable features but were similar to DM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
