Transluminal sternotomy approach lumpectomy-assisted radical thyroid cancer treatment for papillary thyroid cancer in cN0 According to the report of Shanghai CDC, the incidence of thyroid cancer in women in Shanghai has been ranked fifth in the incidence of all tumors in women. According to our hospital, close to 50% of patients admitted in recent years are papillary microcarcinoma (<1cm), and such patients have a better prognosis and longer survival period. For these patients, except for high-risk patients (multiple carcinomas, etc.) and patients with metastases in the lateral neck area, the scope of surgery is often limited to one lobe + isthmus + lymph node dissection in VI. This group of patients also has certain cosmetic requirements due to their better prognosis. How to take into account the cosmetic needs of patients without compromising the outcome of radical thyroid cancer (Figure 1) is a new proposition for surgeons. In terms of the principles of surgical oncology, the surgical field should be restricted to the neck in order to avoid the dissemination of surgical operations, and the available surgical options are more limited. Since Miccoli et al. proposed Minimally Invasive Video Assisted Thyroidectomy (MIVAT), this procedure has been used for the treatment of thyroid diseases with the advantages of short learning curve, aesthetics, minimal invasiveness, few complications and rapid postoperative recovery. In 2000, Miccoli et al. applied the MIVAT technique to papillary thyroid carcinoma (PTC), and radical lumpectomy for thyroid cancer was gradually developed and achieved certain development. The traditional MIVAT incision is located 1-2 cm above the sternal notch (Figure 2), but most national people have more obvious neck scar, so the cosmetic effect of such high access is poor. In order to further reduce the impact of the surgical incision on the patient's aesthetics, the head and neck surgery department adopted a modified sternotomy approach to MIVAT for strictly screened cN0 thyroid cancer patients undergoing radical thyroid cancer surgery, which can meet part of the patients' cosmetic needs without affecting the outcome of radical treatment. It is important to emphasize that not every patient with cN0 thyroid cancer will have the opportunity to undergo MIVAT. It is important to emphasize that not every patient is suitable for a certain type of surgery, and surgical oncology must be the first goal of radical treatment.
