Abstract Background The treatment strategy for metastatic lesions of primary malignant melanoma of the esophagus (PMME) is currently determined on a case-by-case basis, based on the National Comprehensive Cancer Network (NCCN) guidelines for cutaneous melanoma. The NCCN guidelines state that resection should be considered in patients with resectable metastatic recurrence. Herein, we report a case of long-term survival treated with three metastasectomies and two subsequent adjuvant nivolumab therapies for the metastatic recurrence of PMME. Case presentation A 65-year-old female patient with PMME underwent thoracoscopic subtotal esophagectomy, gastric tube reconstruction via the posterior mediastinal route, and cervical esophagogastric anastomosis. Histopathological examination of the resected specimen revealed that the tumor was PMME with tumor invasion into the muscularis propria and no lymph node metastasis. At the age of 68 years, she developed intestinal invagination due to jejunal metastasis of malignant melanoma and underwent resection of the jejunum. Histopathological examination of the resected specimen revealed two metastases of malignant melanoma in the jejunum and one metastasis to the mesenteric lymph node. At the age of 75 years, a recurrence of malignant melanoma was found in the cervical esophagus. She underwent thoracoscopic mobilization of the gastric tube and esophagus followed by cervical esophagectomy and reconstruction with a free jejunum flap. She received 24 courses of nivolumab therapy for 1 year as a postoperative adjuvant therapy. Subsequently, at the age of 78 years, an enlarged left cervical lymph node and a mass in the right lower lobe of the lung were found. She underwent left cervical lymph node dissection and thoracoscopic wedge resection of the right lung. Histopathological examination of the resected specimens revealed that both tumors were metastases of malignant melanoma. At age 79 years, she received eight courses of nivolumab therapy as a second postoperative adjuvant therapy, with no sign of recurrence in a 9-month follow-up period after the third metastasectomy. Conclusion In cases of metastatic recurrence of PMME, aggressive resection of oligometastasis with postoperative adjuvant nivolumab therapy may result in long-term survival.

Introduction: Revision framework surgeries might be required for unilateral vocal fold paralyses. However, outcomes and indications of revision surgeries have not been adequately documented. For a better understanding of indications for the procedure and to help in achieving better vocal outcomes, we performed a retrospective chart review of patients who underwent revision framework surgeries for unilateral vocal fold paralysis. Objectives: This study aimed to present clinical features of patients who underwent revision framework surgeries for the treatment of unilateral vocal fold paralysis. Methods: Of the 149 framework surgeries performed between October 2004 and October 2019, 21 revision framework surgeries were performed in 19 patients. Self-assessments by patients using the voice handicap index-10 questionnaire, and objective aerodynamic and acoustic assessments performed pre- and post-operatively were analyzed using the Wilcoxon’s signed-rank test for paired comparisons. Results: Undercorrection was indicated as reasons for revision surgeries in all cases. The revision techniques included type I thyroplasty, type IV thyroplasty, and arytenoid adduction, and revision surgeries were completed without any severe complication in all cases. Pre- and post-operative voice handicap index-10 scores were obtained in 12 cases, and other parameters were evaluated in 18 cases. Significant improvements were observed in voice handicap index-10 scores, maximum phonation time, mean flow rate, Current/Direct Current ratio, and pitch perturbation quotient. Conclusion: Undercorrection was observed in all patients who underwent revision framework surgeries for unilateral vocal fold paralysis, and the initial assessment and planning are thought to be important in order to avoid revision surgeries. Revision surgeries were performed safely in all cases, and significantly improved vocal outcomes were observed, even after multiple procedures. Revision surgery should be considered for patients with unsatisfactory vocal functions after primary framework surgeries for unilateral vocal fold paralysis.

Purpose: Auditory-perceptual evaluation is essential for the assessment of voice quality. The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) provides a standardized protocol and assessment form for clinicians to analyze the voice quality and has been adapted into several different languages. The aims of this study were to develop the Japanese version of the CAPE-V and to investigate its reliability and validity. Method: The Japanese CAPE-V consisted of the same three speech contexts (vowels, sentences, and conversation) as developed in the original English version. The sentences were designed according to the concepts of the original version and reviewed by Japanese phoneticians. To validate the usefulness of the Japanese CAPE-V, voices of 173 Japanese-speaking subjects (76 subjects with dysphonia and 97 without voice complaints) were evaluated by five experienced judges, according to the Japanese CAPE-V as well as the GRBAS (Grade, Roughness, Breathiness, Asthenia, Strain) scale. Results: The Japanese CAPE-V provided a high interrater reliability (intraclass correlation coefficients [ICCs] > .85 for all the parameters) as well as a high intrarater reliability (ICCs > .85 for all the parameters). In addition, overall severity, roughness, and breathiness in the Japanese CAPE-V were highly correlated with the corresponding dimensions in the GRBAS scale, having Spearman correlation coefficients greater than .8. Conclusion: This study demonstrated the reliability and validity of the newly developed Japanese CAPE-V as an auditory-perceptual evaluation instrument. [ABSTRACT FROM AUTHOR]
