Abstract: Objective: Combined treatment modality, e.g., definitive surgery followed by radiotherapy (RT) and definitive RT with concurrent chemotherapy, has been applied for advanced maxillary sinus squamous cell carcinoma (MSSCC) patients to obtain a better survival with organ preservation in Japan. Methods: The outcome of 40 patients with MSSCC between 1991 and 2007 in our institute was analyzed retrospectively. There were 36 males and 4 females, the average age being 59.5 years (ranging from 34 to 81 years). The median follow-up time was 66.1 months. All the patients had received a combined treatment consisting of definitive surgery, RT, and intra-arterial or systemic chemotherapy. The chemotherapeutic regimen was different depending on the performance status and/or complications of the patients. Since 1998, concurrent chemoradiotherapy with cisplatin, 5-fluorouracil, methotrexate and leucovorin regimen (CCRT–PFML) instead of neo-adjuvant chemotherapy has been applied. Results: The overall 5-year survival rate was 59.2%, the 5-year disease-specific survival rate was 71.7%, and the 5-year organ preservation survival rate was 42.4%. In the group receiving CCRT–PFML, the overall 5-year survival rate was 60.0%, the 5-year disease-specific survival rate was 76.0%, and the 5-year organ preservation survival rate was 60.3%. Conclusion: CCRT–PFML for advanced MSSCC patients is feasible to preserve the organs without reducing the survival rate. [Copyright &y& Elsevier]

To evaluate the feasibility of narrow-field supracricoid partial laryngectomy with cricohyoidoepiglottopexy (NF-SCPL-CHEP). Between 2019 and 2020, five patients with glottic cancers underwent NF-SCPL-CHEP. The mean durations of surgical drains, tracheostomy canula, and nasogastric tube use were evaluated. Length of stay following NF-SCPL-CHEP was compared with that of our open SCPL historical controls. A case summary is provided for the first patients, with detailed information about postoperative management and function. All five patients achieved uneventful postoperative recoveries without major complications. The average time for surgical drains, tracheostomy canula, and nasogastric tube use were 2, 15, and 46 days, respectively. The mean overall hospitalization period was 36 days for NF-SCPL-CHEP patients. The mean period of hospitalization based on our early experiences between 1997 and 2005 with classical open SCPL was 72 days. All patients were fully functional and local recurrences or distant metastases were not encountered during a mean observation period of 39 months. NF-SCPL-CHEP with 6 cm cervical access appeared technically feasible and oncologically sound in this initial clinical experience. An extra 2 cm incision, which enabled lateral neck dissection, was not felt to detract from the overall minimally invasive basis of NF-SCPL-CHEP. The clinical results were encouraging with limited complications and predictable postoperative recovery. The length of stay for patients undergoing NF-SCPL was half that of open SCPL historical controls. Less damages to local circulation may associate with the positive influences. Further study with a large patient sample across multiple institutions are needed to carefully evaluate long-term functional and oncological outcomes. [ABSTRACT FROM AUTHOR]

Objective: In this study, we examine the relationship between developmental insufficiency of mastoid air cells and abnormal morphology of the paranasal sinuses in patients with chronic otitis media (COM) and acquired middle ear cholesteatoma (AMEC) using precise image assessment, in order to evaluate whether the anatomical features of paranasal sinuses has any impact on the pathogenesis in COM and AMEC.Methods: A total of 127 patients, including 45 COM patients and 82 AMEC patients, were enrolled for this study. The existence of nasal septal deviation, the existence of paranasal sinus opacification, the modified Lund-Mackay score, the diameters of the paranasal sinuses, the Vidic classification, mastoid development, and cranial size were assessed by CT examination. A further 76 adult patients who underwent high-resolution CT imaging of their skull bone for other diseases were enrolled as the control.Results: The AMEC group showed a significantly shorter sphenoid length (P < 0.01) and lower Vidic classification score (P < 0.01) compared to the control group in this study. In addition, we observed that patients with AMEC had less pneumatization of the mastoid air cells compared to the control individuals, and that the sphenoid length of the poor MC score group was significantly shorter than that of the good MC score group.Conclusion: Our results suggested that the developmental deficiency in sphenoid length caused by long-standing pediatric rhinosinusitis might indicate the potential of chronic middle ear inflammation in childhood and impact the pneumatization of mastoid air cells. Therefore, chronic rhinosinusitis during the childhood and adolescence might play a role in the pathophysiology of AMEC. [ABSTRACT FROM AUTHOR]- Published

Objective: The Hyodo scoring system during the endoscopic procedure has been proposed as a new tool for evaluating oral intake feasibility. However, the effectiveness of the information obtained from this procedure in predicting aspiration is not fully elucidated. The aim of this study was to assess the significance of clinical factors, including Hyodo scores, for predicting the risk of aspiration.Methods: Five hundred and twenty-eight endoscopic swallowing examinations were performed. Clinical factors, including age, sex, disease type, history of aspiration pneumonia, cognitive function, presence of tracheostomy, presence of vocal cord paralysis, consciousness level on the Japan Coma Scale, ECOG Performance Status, serum albumin level and Hyodo score, were obtained for each examination. The relationship between each of these factors and the presence of aspiration during endoscopic procedure was evaluated.Results: Three hundred and thirty-two patients (62.9%) were scored less than 5, 153 (29.0%) were scored between 5 and 8, and 43 (8.1%) were scored above 8. The number of patients with aspiration was 133 (25.2%). ROC analysis revealed that a cut-off point of 6 for Hyodo score was effective for predicting aspiration, with a sensitivity of 0.65 and a specificity of 0.86. History of aspiration pneumonia (OR 1.87, P<0.001), vocal cord paralysis (OR 2.23, P<0.001), PS≥3 (OR 2.47, P<0.001) and Hyodo score>6 (OR 9.08, P<0.001) were found to be independent predictive factors for aspiration.Conclusion: The Hyodo scoring method was easy for otolaryngologists to perform and the scores were useful for predicting aspiration with moderate sensitivity and high specificity. Hyodo score>6, history of aspiration pneumonia, vocal cord paralysis, and PS≥3 were independent predictive factors for aspiration and that a Hyodo score above 6 was the statistically strongest predictor for aspiration.

Objective The purpose of this study is to validate the concept of lymph node ratio (LNR) in head and neck squamous cell carcinoma (HNSCC). Methods A total of 63 patients with HNSCC who underwent resection of the primary tumor combined with neck dissection in our institution were analyzed in this study. LNR was defined as the number of positive lymph nodes divided by the total number of lymph nodes excised. LNR was categorized into two groups (<0.068 and ≥0.068) according to the results of receiver-operating characteristic plots for determination of the cut-off value. Results LNR ≥ 0.068 was associated with poor overall survival (OS), progression-free survival (PFS) and locoregional recurrence-free survival (LRFS) after resection of the primary tumor combined with neck dissection in patients with HNSCC. Univariate and multivariate data analysis showed that LNR ≥ 0.068 was an independent prognostic factor for OS, PFS and LRFS. Both pathological T stage status (pT3 or 4) and ≥3 positive LNs were also an independent prognostic factors for PFS in patients with HNSCC in our univariate and multivariate analysis. Conclusion These results suggested that LNR could be useful tools in identifying HNSCC patients with poor outcomes. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study is to validate the applicability of new TNM classification for human papillomavirus (HPV)-related oropharyngeal cancer (OPC) in the 8th edition of the American Joint Committee on Cancer (AJCC)/Union for International Cancer Control (UICC) TNM staging system in Japan.Methods: A total of 91 OPC patients treated with radiation-based therapy between November 2001 and July 2015 were analyzed retrospectively in this study. HPV infection status was evaluated using tumor p16 expression.Results: 40 OPC patients (44.0%) had HPV-positive disease in this study. The distribution of disease stage of HPV-positive OPC patients dramatically changed from the 7th edition to the 8th edition of AJCC/UICC TNM classification. However, neither the 8th edition nor the 7th edition of the AJCC/UICC TNM staging system could adequately predict outcomes of HPV-positive OPC patients in our patient series. On the other hand, our multivariate analysis indicated that matted nodes and age ≥63 were independent prognostic factors for progression-free survival. In addition, HPV-positive OPC patients with stage I without matted nodes showed significantly better overall and progression-free survival compared with those with stage I with matted nodes and stages II and III in the 8th edition of the AJCC/UICC TNM staging system (P=0.008, and P=0.043, respectively).Conclusion: Our results suggested that matted nodes of HPV-positive OPC patients might be additionally examined to apply the 8th edition of AJCC/UICC TNM classification for more adequate predicting outcomes of HPV-positive OPC patients.

Abstract: Objective: This study evaluates the utility of fluorodeoxyglucose-positron emission tomography (FDG-PET) in patients with head and neck squamous cell carcinoma (HNSCC) who received concurrent chemoradiotherapy (CCRT). Methods: Sixty-five patients were recruited for this study between November 2002 and April 2007. The FDG-PET scan was performed before treatment and 4–6 weeks after treatment. Results: The mean of maximum standardized uptake value (SUVmax) before treatment at the primary tumor site was 8.1 (range, 2–22). The sensitivity of FDG-PET for the diagnosis of primary tumor site was 98%. The mean of SUVmax after treatment was 2.6 (range, 2–5). The sensitivity, specificity, and accuracy of FDG-PET for the diagnosis of primary tumor site after treatment were 100%, 40%, and 46%, respectively. The mean of SUVmax before treatment at the nodal site was 4.7 (range, 2–16). The mean of SUVmax after treatment was 2.0 (range, 2–6.7). The pre-treatment SUVmax of T2, T3, and T4 stages were significantly higher than that of the T1 stage. The N stage had no correlation in terms of the pre-treatment nodal site SUVmax. Conclusion: Our results indicate that FDG-PET is a useful imaging method for evaluating the response of CCRT in patients with HNSCC. However, performing FDG-PET 4–6 weeks after treatment may be too early as it may give false-positive results due to fibrosis and scarring. [Copyright &y& Elsevier]

Abstract: Objective: To review our experience in the treatment of concurrent chemoradiotherapy (CCR) for patients with advanced squamous cell carcinoma of the head and neck (SCCHN) and to evaluate the different factors affecting survival and primary organ preservation. Methods: We reviewed the records of 101 patients with SCCHN treated with CCR between February 1998 and April 2004. Of 101 patients, 76 were treated with a cisplatin, 5-fluorouracil, methotrexate, and leucovorin (PFML) regimen and 25 were treated with a carboplatin and uracil-tegafur (CBDCA-UFT) regimen. Overall survival (OS), disease-specific survival (DSS) and DSS with primary organ preservation were estimated using Kaplan-Meier methods. The log-rank test and Cox proportional hazards regression were employed to identify significant prognostic factors for OS, DSS, and DSS with primary organ preservation. Results: The 5-year OS and DSS for all patients were 51.6 and 67.4%, respectively. On multivariate analysis, resectability of the tumor and degree of histological differentiation were significant predictors of survival for patients undergoing CCR; T stage and differentiation were significant prognostic factors for primary organ preservation. Conclusion: In the treatment of CCR for advanced SCCHN, the survival rate of the patients with resectable tumors was excellent and significantly greater compared with the patients with unresectable tumors. T1 to T3 disease in patients with advanced resectable SCCHN is a good predictor of organ preservation. CCR may improve not only primary organ preservation (local control) but also survival in patients with poorly differentiated tumors. [Copyright &y& Elsevier]

Objectives: The aim of this study is to assess the utility of FDG-PET in the evaluation of therapeutic effects at 4 weeks after the completion of the concurrent chemoradiotherapy (CCR) in patients with head and neck squamous cell carcinoma (HNSCC).Methods: Thirty-one patients with previously untreated HNSCC were retrospectively investigated about FDG-PET, CT, MRI and biopsies of the carcinoma before and 4 weeks after the treatment.Results: The results of pathological examinations after CCR showed 6 residual cases and 25 ones with a pathologically complete response (pCR). The specificity of FDG-PET was 80%, although the sensitivity was limited to 67%.Conclusions: FDG-PET has a high specificity but limited sensitivity to discriminate residual cancer from fibrosis or scar at 4 weeks after CCR. FDG-PET at 4 weeks after CCR was too early to perform because of limited sensitivity. [ABSTRACT FROM AUTHOR]- Published
