This is a real world study aiming to observe the efficacy and safety of Anlotinib capsules in patients with advanced medullary thyroid carcinoma, and to summarize the treatment experience in a broad population of patients.
Patients voluntarily joined the study, signed the informed consent, and had good compliance;
Patients ≥18 years of age (at the time of signing the informed consent); Eastern Cooperative Oncology Group Performance Status (ECOG-PS) score: 0-2; Expected survival of more than 3 months;
Patients were pathologically confirmed as inoperable locally advanced or metastatic medullary thyroid carcinoma (MTC), possessing imaging or clinical evidence of disease progression within the first 14 months of enrollment;
Having at least one measurable lesion (assessed by Response Evaluation Criteria In Solid Tumors (RECIST) 1.1);
Patients currently have or had other malignancies within 3 years. Patients with the following two conditions can be included in the group: Continuous 5-year disease-free survival (DFS) was achieved for other malignancies treated with a single operation. Cured cervical carcinoma in situ, non-melanoma skin cancer, and superficial bladder tumors [Ta (non-invasive tumor), Tis (carcinoma in situ) and T1 (the tumor infiltrates the basal membrane)];
Major surgical treatment, open biopsy, or significant traumatic injury were received within 28 days before the beginning of the treatment;
Having ≥ grade 2 myocardial ischemia or myocardial infarction or arrhythmia (including QTc ≥450ms (male), QTc ≥470ms (female) and ≥ grade 2 congestive heart failure (classified by New York heart association, NYHA));
Active or uncontrolled severe infection (≥ Common Terminology Criteria for Adverse Events (CTC AE) 2 grade of infection);
