Before medication, the patient’s CT scan revealed squamous cell carcinoma of the left tonsil. Postoperative pathological report diagnosed it as well-differentiated squamous cell carcinoma. The patient began using CHA for injection alone. During this period, anticoagulant drugs were used to treat thrombosis, but due to significant side effects, they were used no longer after two uses. Subsequently, the patient continued using CHA for injection exclusively. A follow-up examination after a 4-month medication showed no clear signs of thrombosis. Postoperative CT showed no abnormalities. Since then, multiple reexaminations showed no recurrence and metastasis. After 4 years and 8 months of medication, there was no abnormal enhancement in the lesion. Up to now, the patient is still treated with the CHA and is in good condition, just like a normal healthy person.
