The distal end of parotid duct is often inevitably resected en-block with the buccal mucosa cancer to obtain safety margin and prevent local recurrence. Ligation of duct frequently causes complications like cheek swelling, fistula and gland function loss. The authors describe a novel procedure of combined use of autologous vein graft and vascular coupler to reconstruct the parotid duct defect for buccal mucosa cancer patients who undergo radical neck dissection and free-flap reconstruction, no lumen-stent or cannula is needed. Case examples are shown to illustrate the operative details and different outcomes for two kinds of orifice site choices. Key factors for success include the proper use of Coupler device, right choice of new orifice location and maintenance of lumen patency. For buccal mucosa cancer patients, this novel method for parotid duct reconstruction could effectively reduce postoperative complications and preserve the parotid gland function.

Purpose: Boron neutron capture therapy (BNCT) perform as a treatment option for locally advanced or recurrent unresectable head and neck cancers since June 2020 in Japan. The effect of BNCT on parotid carcinoma, which presents a variety of histologic types, remains unclear. The object of this study was to investigate the antitumor efficacy of BNCT against parotid gland carcinoma by focusing on LAT1, which is involved in the uptake of L-BPA, the boron compound used in BNCT.

Background: Salivary duct carcinoma (SDC) is a highly aggressive salivary gland malignancy with poor prognosis. The aim was to investigate the prognostic factors and survival outcomes in a cohort of SDC patients.
Materials And Methods: This study retrospectively analyzed the clinicopathological data of 61 SDC patients treated at the First Medical Center of the PLA General Hospital between January 2010 and December 2020.

Backgroud: Salivary duct carcinoma (SDC) is a rare and aggressive malignancy with a generally dismal prognosis and no standard of care established, despite a known association with epidermal growth factor receptor 2 (HER2) and androgen receptor (AR) over-expression.
Case: We report the case of a 64-year-old female with extra- and intracranial metastases of SDC with evidence of AR and HER2 overexpression. After progression on first line chemotherapy, was administered neratinib, a pan-Erb2 receptor tyrosine kinase inhibitor.
