ABSTRACT

To evaluate the postoperative swallowing function in head and neck cancer patients, videofluoroscopic examination of swallowing (VF) proved useful as a qualitative evaluation, but was complex as a quantitative evaluation. We made use of the AsR score which consisted of a 10-point scale as a quantitative evaluation of VF. To identify the usefulness of the AsR score, 146 patients who had undergone extensive resection and reconstruction with free flaps or pedicle grafts were reviewed. The AsR score of VF for the first time after surgery was defined as "first score", and at the last time in the hospital was defined as "last score". The correlations between the first score and continuity of direct therapy, and between the last score and way of nutrition at the time of discharge were examined. Using the ROC (receiver operator characteristic) analysis and the AUC (area under the curve) the cut-off values of the AsR score were estimated. One hundred and thirty one patients could continue direct therapy after the first time of VF. The first score detected continuity of direct therapy with high accuracy (AUC = 0.946), furthermore using a cut-off of 5, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were about 96.2%, 86.6%, 98.4%, and 72.2%, respectively. At the time of discharge, 138 patients had no limitation of oral intake and 8 patients had a limitation e.g. PEG (n = 7) and a total laryngectomy for preventing aspiration (n = 1). The last score detected oral intake ability with no limitation with high accuracy (AUC = 0.925). Using a cut-off of 6, the sensitivity, specificity, PPV and NPV were about 82.6%, 87.5%, 99.1% and 22.6%, respectively. The AsR score is useful as a quantitative evaluation of postoperative swallowing function in oral cancer patients.

ABSTRACT

BACKGROUND AND AIMS: Although endoscopic submucosal dissection (ESD) has been applied for superficial pharyngeal cancer, no prospective trials have been reported. To investigate the efficacy and safety of ESD for superficial pharyngeal cancer, we conducted a prospective phase II trial. METHODS: Fifty-four patients with 73 lesions were enrolled from September 2010 to August 2014, and ESD was performed. The primary endpoint was the complete resection rate. Secondary endpoints were safety, recurrence-free survival, overall survival, and incidence of metachronous pharyngeal cancer. RESULTS: Fifty-four patients had stage 0-III cancer: stage 0, n = 22; stage I, n = 14; stage II, n = 17; and stage III, n = 1. The en bloc resection rate was 100%, and the complete resection rate was 79.5% (58/73 lesions; 95% confidence interval, 68%-88%). No serious adverse events related to ESD were encountered. Four patients required nasogastric intubation and feeding. No patients required percutaneous endoscopic gastrostomy and tracheotomy. Swallowing, speech, and airway functions were preserved in all patients. One of the 54 patients died of an unrelated illness. Median follow-up was 27 months (range 6-55 months). Local cervical lymph node metastasis was observed in 1 patient, and the case was salvaged successfully with lymph node dissection. The 3-year overall and recurrence-free survival rates were 97.7% and 98.1%, respectively. Cumulative development of multiple cancers of the pharynx at 3 years was 18.4%. CONCLUSIONS: ESD appears to be a safe and effective minimally invasive treatment in patients with superficial pharyngeal cancer. ( CLINICAL TRIAL REGISTRATION NUMBER: UMIN000003623.).

ABSTRACT

A retrospective analysis of 263 patients with previously untreated squamous cell carcinoma of the tongue between 2000 and 2010 was performed. Those patients, who received preoperative chemotherapy, had a history of head and neck cancer or had previously received radiotherapy for the other disease, were excluded. All patients underwent a surgical procedure as a part of the initial treatment. Patients with close or microscopically involved margins of resection, INF (Infiltrative growth pattern) gamma or at least two involved nodes were classified as high risk patients. Postoperative radiotherapy (PORT) was undertaken for the high risk patients. After a median follow-up of 72 months, the 5-year overall survival and 5-year cause-specific survival were as follows: 79.1%, 85.0% in all stages, 82.7%, 91.2% in Stage I (n = 76), 86.7%, 89.0% in Stage II (n = 98), 71.5%, 78.6% in Stage III (n = 57), and 61.5%, 69.1% in Stage IV (n = 32). Patients without high risk features had significantly higher overall survival rate than those in the case of high risk patients, despite receiving no PORT. For high risk patients, PORT significantly improved the locoreginal control rate, but the overall survival rate did not improve.
