[A Case of Laparoscopic Low Anterior Resection after TNT for Rectal Cancer with Seminal Vesicle Invasion].

Local control is important in the treatment of locally advanced rectal cancer. Recently, an increasing number of centers are offering total neoadjuvant therapy(TNT)for local and systemic control. A 71-year-old man with Ra rectal cancer was referred to our department, and was diagnosed as cT4b(seminal vesicle)N2aM0, cStage Ⅲc by CT and MRI. The diagnosis of locally advanced rectal cancer led to the decision to perform TNT. Laparoscopic low anterior resection, combined vasectomy, and ileostomy were performed, with an operating time of 549 minutes and blood loss of 130 mL. Histopathological diagnosis was ypT3N0M0, ypStage Ⅱa. The histological response to treatment was Grade 2. One year after surgery, the patient is alive and with no recurrent cancer.
