Early enteral nutrition and mobilization following head and neck surgery with free flap reconstruction.

BACKGROUND: Perioperative management methods that reduce surgery-associated invasiveness and improve the quality of postoperative recovery are being promoted as enhanced recovery after surgery programs in various areas. Early enteral nutrition and mobilization are essential elements for enhanced recovery after surgery; however, their safety and feasibility are unclear in head and neck surgery with free tissue transfer reconstruction. This study aimed to clarify these uncertainties. METHODS: This is a retrospective before-after study. From 2018 to 2022, 187 and 173 patients received conventional management on or before April 2020 and early management on or after May 2020, respectively. The conventional management and early management groups received enteral nutrition and mobilization on postoperative days 2 and 1, respectively. The primary outcome for safety assessment was the incidence of complications. The secondary outcome was the compliance rate of conventional management or early management for feasibility assessment and the length of hospital stay. RESULTS: The clinical tumour-node-metastasis stage and American Society of Anesthesiologists physical status showed significant differences between the groups. In multivariable analysis, the early management group demonstrated a significantly lower incidence of treatment-required complication classified Clavien-Dindo Grade 2 and above (odds ratio = 0.57; 95% confidence interval = 0.31-0.92) and lower wound infection (odds ratio = 0.53; 95% confidence interval = 0.31-0.92). The early management group had lower compliance rate than the conventional management group; however, no statistically significant difference was observed (79.8% vs. 85.0%, P = 0.21). CONCLUSION: Early management is safe and feasible following head and neck surgery with free tissue transfer reconstruction. It could reduce the complication rate and is considered a useful postoperative management method.

Nasopharyngeal Carcinoma Treated With Photoimmunotherapy.

Photoimmunotherapy is a new treatment modality in which a tumor-targeting monoclonal antibody is combined with a photoactivated dye and a laser is applied to destroy tumor cells. In Japan, insurance reimbursement for this treatment started in January 2021 for unresectable locally advanced or locally recurrent head and neck cancer. We used photoimmunotherapy to treat two patients with recurrent nasopharyngeal squamous cell carcinoma (NPSCC). The first patient was diagnosed with NPSCC (T1N0M0) and treated with definitive radiotherapy, leading complete response. A local recurrence was observed and treated with photoimmunotherapy. Seven months have passed, complete response is archived. The second patient was diagnosed with NPSCC (cT2N1M1). Multimodal therapy led to a complete response for all lesions. A local recurrent lesion appeared, and photoimmunotherapy has been repeatedly performed. The lesion was controlled as a stable disease for about one year. Photoimmunotherapy could be an effective treatment for local recurrence of NPSCC after radiotherapy.
