Abstract
Patients with aortic arch malformations may present with recurrent inferior laryngeal nerve abnormalities that require special attention. Herein, we reported a case of thyroid surgery in a patient with a right aortic arch. The left inferior laryngeal nerve was presumed to be the right inferior laryngeal nerve by confirming the location of the aortic arch and subclavian artery, and the presence of the ductus arteriosus on preoperative computed tomography. Continuous intraoperative nerve monitoring is useful for safe surgery in patients with possible inferior laryngeal nerve abnormalities. Laryngoscope, 134:1986-1988, 2024.

Abstract
BACKGROUND It is controversial whether transoral resection for early pharyngolaryngeal cancer preserves swallowing function and quality of life. We investigated swallowing function and quality of life before and after transoral videolaryngoscopic surgery (TOVS). METHODS Seventy-three patients with pharyngolaryngeal cancer who underwent TOVS between July 2012 and July 2022 were enrolled in this prospective analysis. The Hyodo score and European Organization for Research and Treatment of Cancer Quality of Life Questionnaires were recorded preoperatively and at three, six, and 12 months postoperatively, in addition to the postoperative functional outcome swallowing scale (FOSS) at six months postoperatively. RESULTS Although most patients could consume food orally without restrictions with a preferable FOSS score, 23 patients showed impaired Hyodo scores. Age ≥65 years significantly predicted impaired swallowing. Sub-scores of the impaired patient group showed worsening for the glottal closure reflex when the endoscope touched the epiglottis or arytenoid, as well as a reduction in the extent of pharyngeal clearance following the ingestion of blue-dyed water. CONCLUSION After TOVS, swallowing function is generally well preserved. Elderly patients, especially those with laryngeal hypoesthesia and poor clearance, are at risk of swallowing dysfunction.

Abstract
BACKGROUND The abscopal effect is a rare phenomenon in which localized radiation therapy triggers tumor reduction in nontargeted areas. Although this phenomenon has been observed in various cancer types, it remains infrequent and not fully understood. CASE Two patients with maxillary sinus cancer with distant metastases were treated with radiotherapy after immune checkpoint inhibitor (ICI) therapy. The patients demonstrated abscopal effects following ICI therapy and radiotherapy, showing shrinkage in metastatic areas not directly targeted by radiation. CONCLUSION This report was reviewed to examine the synergistic effects of ICI and radiotherapy and to identify optimal strategies to enhance the abscopal effect in clinical practice. It has also touched on various ongoing debates and clinical trials aimed at understanding and exploiting this effect to improve cancer treatment. The exact mechanisms and optimal treatment protocols remain areas for future research.

Abstract
BACKGROUND Transoral videolaryngoscopic surgery (TOVS) is widely used in Japan, and conventional two-dimensional (2D) endoscopic methods have been established. Three-dimensional (3D) endoscopic surgery offers superior distance perception because it provides stereoscopic views. Recently, we have developed 3D endoscopy for TOVS (3D TOVS). METHODS This study included 46 patients with pharyngeal cancer who underwent 3D TOVS. The perioperative complications and survival curves were retrospectively analyzed. RESULTS One patient with oropharyngeal cancer who underwent neck dissection and transoral resection simultaneously experienced postoperative hemorrhage of the neck. Another patient with oropharyngeal cancer underwent hemostasis for postoperative pharyngeal hemorrhage. There was one case of aspiration pneumonia. One patient developed cervical lymph node recurrence; however, there was no local recurrence or primary mortality. The 2-year overall survival, disease-specific survival, local control rates, locoregional control rate, and invasive disease-free survival were 90.9%, 100%, 100%, 97.4%, and 79.9%, respectively. CONCLUSIONS Three-dimensional endoscopy can be safely applied to TOVS.

Abstract
BACKGROUND Shoulder syndrome can be reduced by preserving the spinal accessory nerve (SAN). However, it is unclear whether performing level IIb preservation will decrease the risk of SAN injury and shoulder syndrome. AIMS/OBJECTIVES We investigated whether neck dissection with level IIb preservation can reduce shoulder dysfunction and postoperative quality of life (QOL) in head and neck cancer patients. MATERIAL AND METHODS This prospective observational study enrolled patients who underwent neck dissection from 2011 to 2014. Patients were divided into three groups (level IIb preservation group [group 1], IIb dissection group [group 2], and IIb and V dissection group [group 3]). Postoperative shoulder function and QOL were evaluated among the three groups. RESULTS There were a total of 35 neck sides in three groups, with nine neck sides in group 1, 16 neck sides in group 2, and 10 neck sides in group 3. Although the results showed less shoulder dysfunction in group 1 at early postoperative period. The QOL in group 1 was preserved in the early postoperative period. CONCLUSIONS AND SIGNIFICANCE Neck dissection with level IIb preservation may help reduce shoulder syndrome and maintain QOL in the early postoperative period.

Abstract
OBJECTIVE This study aimed to evaluate the clinical effectiveness of chemotherapy following immune checkpoint inhibitors (ICI). The association between inflammatory and nutritional factors and prognosis has also been investigated. METHODS We retrospectively reviewed the medical records of recurrent or metastatic head and neck squamous cell carcinoma (RMHNSCC) patients who received chemotherapy following ICI therapy. The response rate and survival after chemotherapy, and nutritional and inflammatory factors, were examined. RESULTS The ICI before chemotherapy was nivolumab in 36 patients (70.6%) and pembrolizumab in 15 patients (29.4%). The chemotherapy regimens consisted of PTX in 32 patients (62.7%), PTX + Cmab in 9 (17.6%), and S1 in 10 (19.6%). The median overall survival (OS) was 20 months (95% CI 12-25), the estimated 12-month OS rate was 63.3%, the median progression-free survival (PFS) was 5 months (CI 4-6), and the 12-month PFS estimate was 8.9%. Univariate analysis significantly correlated Neutrophil-to-Lymphocyte Ratio (NLR), platelet-to-lymphocyte ratio (PLR), controlling nutritional status score (CONUT), and prognostic nutrition index (PNI) with OS and PFS. Additionally, these factors were significantly correlated with OS and PFS in the log-rank tests. CONCLUSIONS Chemotherapy following ICI is highly effective. There were no significant differences in the chemotherapy regimens. Inflammatory and nutritional factors may associate with patient prognosis after chemotherapy.

Abstract
Background Transoral salvage surgery has the potential to preserve a patient's quality of life. Therefore, we investigated the outcomes, safety, and risk factors for postoperative complications of salvage transoral videolaryngoscopic surgery (TOVS) for recurrent hypopharyngeal carcinoma after radiotherapy (RT) or chemoradiotherapy (CRT). Methods This retrospective analysis enrolled patients with hypopharyngeal cancer who had a history of RT or CRT and underwent TOVS from January 2008 to June 2021. The factors related to postoperative complications, postoperative swallowing functions and survival rates were analyzed. Results Seven patients (36.8%) of the 19 patients developed complications. Severe dysphagia was the primary complication, and post-cricoid resection was a complication risk factor. The FOSS score was significantly lower in the salvage treatment group. The survival rates were: 3-year overall survival: 94.4%; disease-specific survival: 94.4%; 5-year overall survival: 62.3%; and disease-specific survival: 86.6%. Conclusions Salvage TOVS for hypopharyngeal cancer was feasible, and oncologically and functionally reasonable. Level of Evidence: 2b.

Abstract
Magnetic resonance imaging (MRI) is a more useful diagnostic modality for detecting paranasal tumors compared with computed tomography (CT). We encountered a case of malignant lymphoma of the maxillary sinus. Although CT findings suggested malignancy, MRI findings indicated an inflammatory disease. The patient was a 51-year-old man with a chief complaint of right maxillary toothache. Edema in the right middle meatus and bloody rhinorrhea were observed. CT revealed r ight maxillary s inus shadow with partial bone loss, suggesting malignancy. However, MRI performed two weeks later showed an internal homogeneous lesion with neither contrast effect, nor invasion outside the maxillary sinus. The patient also had no fever, weight loss, or night sweats. Additionally, no palpable cervical lymphadenopathy was observed. Endoscopic sinus surgery was performed to confirm the diagnosis. Upon opening the maxillary sinus, highly viscous retention and a large amount of yellowish-white debris were observed. Allergic fungal rhinosinusitis was suspected. However, histopathological analysis of the debris established a diagnosis of malignant lymphoma. The debris exhibited pathological findings of necrosis. The patient remained in remission after undergoing radiochemotherapy. Malignant lymphomas of the paranasal sinuses, which have a minimal tendency for invasion but with considerable predominance of necrosis, may be diagnosed as an inflammatory disease, based on MRI findings. In cases in which a thorough physical examination could not rule out malignant lymphomas, an endoscopic biopsy should be immediately considered.

Abstract
This study aimed to determine the prognostic value of inflammatory and nutritional biomarkers of immune checkpoint inhibitor (ICI) therapy for recurrent or metastatic squamous cell carcinoma of the head and neck (RMHNSCC) and to identify the most useful factor for prognosis assessment. We retrospectively reviewed the medical records of patients with RMHNSCC who received ICI therapy. The response rate for ICI therapy and the relationship between inflammatory and nutritional biomarkers and overall survival were examined. The included biomarkers did not correlate with an objective response rate but were associated with a disease control rate. Univariate analysis showed significant correlations between the serum albumin level, C-reactive protein level, platelet to lymphocyte ratio, neutrophil to lymphocyte ratio, lymphocyte to monocyte ratio (LMR), systemic immune-inflammation index, and controlling the nutritional status score and overall survival; multivariate analysis showed that LMR was significantly correlated with overall survival. LMR was the most important biomarker according to the machine learning model. This study suggests that LMR may be the most useful biomarker for predicting the prognosis of ICI treatment for RMHNSCC.

Abstract
BACKGROUND/AIM In December 2019, pembrolizumab was approved in Japan for the treatment of head and neck cancer with recurrence or distant metastasis, making it a new option for first-line treatment. However, there are still many unanswered questions about Overall survival (OS), Progression free survival (PFS), adverse events including immune-related adverse events (irAEs), and biomarkers. AIMS/OBJECTIVES The aim of this study was to retrospectively review first-line treatment of head and neck cancer with recurrence or distant metastasis treated with pembrolizumab and to determine whether Combined positive score (CPS) is still useful as a biomarker in the clinical practice. MATERIAL AND METHODS We retrospectively reviewed clinical records of 20 patients who received pembrolizumab as first-line treatment for head and neck cancer with recurrence or distant metastasis between December 2019 and March 2021. RESULTS Age ranged from 45 to 83 years (median 66 years), 17 male patients and 3 female patients. The response rate was 40%, and the disease control rate was 60%. OS and PFS in patients with CPS < 1 were significantly worse than those with CPS ≤ 1 (CPS-positive patients). The OS and PFS of patients with CPS < 1 were s ignificantly worse than those of p atients with 1 < = CPS (CPS-positive p atients), and there was no significant difference between the group with CPS between 1 and 20 and the group with CPS over 20. And we experiences several CR cases with high CPS. CONCLUSION CPS is a useful biomarker for pembrolizumab. SIGNIFICANCE There are no reported cases of CR after two courses of pembrolizumab in head and neck cancer. There are no reports of pembrolizumab in patients with head and neck cancer in Japan.

Abstract
OBJECTIVES With the advent of new optical technologies, early pharyngolaryngeal cancerous lesions can be better visualized. Although the conventional transnasal approach offers great views of the hypopharynx and larynx, the visualization of the oropharynx and palatine tonsils is limited. Through the transoral insertion of a flexible video-laryngoscope, direct views of the oropharynx and oral cavity can be obtained. Thus, transoral examination may contribute to primary detection of cancers of unknown primary (CUP). METHODS Eighty-five CUP patients from Tokai University were included retrospectively in this study, from 2006 to 2017. Starting in 2010, we employed the transoral examination in addition to our conventional method. The primary detection rates were compared before and after 2010. Oropharyngeal primaries were further analyzed for tumor subsite and p16 status. RESULTS The overall primary detection rate did not improve with the addition of transoral examination. However, greater numbers of oropharyngeal primaries were detected. The oropharyngeal lesions detected by transoral examination were mainly p16 positive, located on the palatine tonsil. CONCLUSION Transoral examination is a noninvasive, easy method to adopt in an outpatient setting, and a promising technique to improve tumor detection in this era of human papillomavirus-associated head and neck cancers. LEVEL OF EVIDENCE 3.

Abstract
BACKGROUND The correlation between genomic mutations (or the overexpression of abnormal proteins) and prognosis in temporal bone squamous cell carcinoma (TBSCC) is not clear. We investigated the overexpression of EGFR and p53 as a pathological biomarker for predicting the clinical course of patients with TBSCC. METHODS We performed a retrospective review of 22 TBSCC cases treated in Tokai University Hospital between January 2005 and October 2016. We assessed the overexpression of EGFR and p53 in TBSCC patients through immunohistochemical staining. We also evaluated the association between the overexpression of these proteins and clinicopathological variables, including survival outcomes. RESULTS The primary lesion in all patients was the external auditory canal. Nine (40.9%) patients were EGFR positive, and 9 (40.9%) were p53 positive. The 5-year overall survival rate for EGFR-positive patients (55.6%) was significantly lower (p = 0.043) than that of the EGFR-negative patients (92.3%). CONCLUSION EGFR overexpression in TBSCC patients may be a prognostic biomarker.

Abstract
METHODS A 42-year-old woman presented to our clinic with tongue pain and dysarthria. She had a smoking history of 22 pack-years and no history of alcohol consumption. A deep ulcer at the left side of the tongue and induration across the whole tongue were observed. The bilateral cervical lymph nodes were palpable. A biopsy from the ulcer revealed squamous cell carcinoma. PET/CT showed sternal bone metastasis resulting in the final diagnosis of left-sided oral tongue cancer (cT4aN2cM1). Systemic chemotherapy treatment involving 6 courses of the EXTREME regimen followed by weekly cetuximab administration was indicated. RESULTS After the first two courses, diminished tongue pain and improved dysarthria were observed; complete response was obtained after 6 courses. Re-examination of the biopsy specimen showed that the tumor was p16 positive. The p16 protein is a surrogate marker for HPV, but in this case HPV in-situ hybridization was negative. Locoregional or distant failure were not observed during the 5-year follow-up period. CONCLUSIONS The treatment regimen unexpectedly proved successful. It may be beneficial to examine p16 expression in oral tongue cancer to identify patients that are more likely to benefit from the EXTREME treatment regimen.

Abstract
Chemical burns of the paranasal sinus are rare; therefore, assessment methods for treatment of and prognoses for the exposure site are unknown. We experienced a case in which a hydrochloric acid burn of the paranasal sinuses caused irreversible tissue damage. Computed tomography is useful for identifying the exposure site and assessing tissue damage over time. Identification of the exposure site and proactive washing are recommended for patients with chemical burns of the paranasal sinuses. Laryngoscope, 131:E2490-E2493, 2021.

Abstract
BACKGROUND Induction chemotherapy (IC) in locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN) often compromises compliance with subsequent chemoradiotherapy (CRT), which negatively affects outcomes. Here, we assessed the combination of paclitaxel (PTX), carboplatin (CBDCA), and cetuximab (Cmab) as IC for unresectable LA-SCCHN. METHODS Induction chemotherapy consisted of weekly CBDCA area under the plasma concentration-time curve = 1.5, PTX 80 mg/m2 and Cmab with an initial dose of 400 mg/m2 followed by 250 mg/m2 for 8 weeks. Following IC, CDDP (20 mg/m2 , 4 days × 3 cycles) and concurrent radiotherapy (70 Gy/35 fr) were started. Primary endpoint was the proportion of CRT completion (%CRT completion). PCE was planned to be deemed effective if the Bayesian posterior probability (PP), defined as the probability that %CRT completion was larger than the threshold value of 65%, exceeded 84%. RESULTS Thirty-five patients were enrolled. Cases were hypopharynx/oropharynx/larynx in 17/17/1 patients, all at Stage IV. Of 35 patients, 34 (97%) completed IC and 32 received CRT and met the criteria of full analysis set (FAS). In FAS, the %CRT completion was 96.9%, and PP was 99.9%, exceeding the prespecified boundary of 84%. Mean cumulative dose and relative to dose intensity of CDDP in CRT was 232.5 mg/m2 and 100%, respectively. Response rate was 88.6% by IC and 93.8% in the CRT phase. Three year overall survival was 83.5%. Main grade 3 toxicities included neutropenia (11.4%) and skin rash (5.7%) during IC; and oral mucositis (31.3%) and neutropenia (12.5%) during CRT. No grade 4 toxicity or treatment-related death was seen. CONCLUSIONS PCE as IC was feasible, with promising efficacy and no effect on compliance with subsequent CRT in unresectable LA-SCCHN.

Abstract
Lacrimal sac tumors are rare and difficult to diagnose. We present a case of coexisting lacrimal sac adenocarcinoma and transitional cell carcinoma in a 73-year-old woman who presented with swelling of the inner canthus. Biopsy identified the growth as an adenocarcinoma. After dissection of the lacrimal carcinoma via a lateral rhinotomy, histopathologic examination confirmed the adenocarcinoma and identified a coexisting transitional cell carcinoma. A recurrence developed, but only of the adenocarcinoma component. For the recurrence, the patient was treated with wide resection, including the orbital contents, and subsequent irradiation. At 49 months postoperatively, the patient remained alive but with a lung metastasis. Wide resection was the key to treatment.

Abstract
Chiral 3-oxocycloalkanecarbonitriles were prepared by fractional crystallization and crystallization-induced diastereomer transformation (CIDT) of diastereomeric ketals with (1R,2R)-1,2-diphenylethane-1,2-diol. Investigation of the crystal structures by X-ray diffraction analysis revealed that the difference in hydrogen bonds caused the discrepancy of the solubilities between (R) and (S) diastereomers. Furthermore, CIDT to afford the (R)-diastereomer in good yield (95% yield) and with high diastereoselectivity (97% de) was accomplished, which is the first example of CIDT of neutral compounds via formation of the diastereomeric ketal with (1R,2R)-1,2-diphenylethane-1,2-diol. Chiral 3-oxocyclopentanecarbonitrile was prepared in good yield and with high diastereoselectivity by crystallization-induced diastereomer transformation of the corresponding diastereomeric ketal.![]()

Abstract
Hybrid transplantation of skeletal muscle-derived multipotent stem cells (Sk-MSCs) and bioabsorbable polyglyconate (PGA) felt was studied as a novel regeneration therapy for the transected recurrent laryngeal nerve (RLN). Sk-MSCs were isolated from green fluorescence protein transgenic mice and then expanded and transplanted with PGA felt for the hybrid transplantation (HY group) into the RLN transected mouse model. Transplantation of culture medium (M group) and PGA + medium (PGA group) were examined as controls. After eight weeks, trans-oral video laryngoscopy demonstrated 80% recovery of spontaneous vocal-fold movement during breathing in the HY group, whereas the M and PGA groups showed wholly no recoveries. The Sk-MSCs showed active engraftment confined to the damaged RLN portion, representing favorable prevention of cell diffusion on PGA, with an enhanced expression of nerve growth factor mRNAs. Axonal re-connection in the HY group was confirmed by histological serial sections. Immunohistochemical analysis revealed the differentiation of Sk-MSCs into Schwann cells and perineurial/endoneurial cells and axonal growth supportive of perineurium/endoneurium. The number of axons recovered was over 86%. These results showed that the stem cell and cytokine delivery system using hybrid transplantation of Sk-MSCs/PGA-felt is a potentially practical and useful approach for the recovery of transected RLN.

Abstract
The prognosis of advanced temporal bone cancer is poor, because complete surgical resection is difficult to achieve. Chemoradiotherapy is one of the available curative treatment options; however, its systemic effects on the patient restrict the use of this treatment. A 69-year-old female (who needed peritoneal dialysis) presented at our clinic with T4 left external auditory canal cancer and was treated with cetuximab plus radiotherapy (RT). The primary lesion showed complete response. The patient is currently alive with no evidence of disease two years after completion of the treatment and does not show any late toxicity. This is the first advanced temporal bone cancer patient treated with RT plus cetuximab. Cetuximab plus RT might be a treatment alternative for patients with advanced temporal bone cancer.

Abstract
BACKGROUND Several reports have suggested that selected patients with human papillomavirus-related oropharyngeal cancer can be managed with surgery alone. We retrospectively reviewed tonsillar cancer cases to analyze treatment de-intensification after transoral resection. METHODS Eighteen patients with tonsillar cancer who had undergone transoral resection were included. The patients' characteristics, p16 status, adverse features, clinical course, overall survival, and relapse-free survival according to p16 status were retrospectively examined. RESULTS Four lesions showed positive surgical margins and one lesion showed close surgical margin; these patients were treated with postoperative irradiation. Seven p16-positive patients had multiple node metastases and two had extracapsular spread. No p16-positive patients agreed to postoperative irradiation, and recurrence within the surgical field was not observed. The five-year overall and relapse-free survival rates were 89% and 74%, respectively. The five-year relapse-free survival rates of p16-positive and p16-negative patients were 81% and 50%, respectively (p = .075). CONCLUSIONS Postoperative irradiation for cervical lymph node metastases might be avoidable in selected patients with human papillomavirus-related tonsillar cancer. LEVEL OF EVIDENCE 4.

Abstract
The glass dosemeter, which is a component of the glass badge (GB), is used on the basis of radiophotoluminescence phenomenon. Chiyoda Technol Corporation has been providing it for personal monitoring services since the year 2000. Through the experience acquired over 15 y, Chiyoda Technol Corporation has developed the New GB, which was brought into service in Japan for radiation monitoring in January 2014. The New GB was developed with the aim of improving radiation measurement methods, streamlining the provision of GB monitoring services and realising a user-friendly dosemeter. As the result, in this study, the measurable energy range covered for beta rays was expanded to include those emitted from 147Pm, the directional dependency was improved, a film was designed to remove secondary electrons arising from interactions between incident photons and the metallic filters, and the arrangement of the metallic filters was optimised.

Abstract
Adult rhabdomyosarcoma (RMS) is a highly aggressive tumor. Multidisciplinary treatment is important. However, the role of surgery is controversial. The purpose of this study was to reveal the role of a delayed primary excision (DPE) after induction chemotherapy (IC) in localized nonmetastatic adult head and neck RMS. We retrospectively reviewed 24 adult head and neck RMS. Treatment was classified into the following two groups: the DPE group, who received IC followed by surgery, postoperative radiotherapy, and adjuvant chemotherapy (17 patients); the chemoradiotherapy (CRT) group, who received IC followed by chemoradiotherapy (seven patients). We analyzed the efficacy of IC, local control rate (LCR), and overall survival (OS). In the DPE group, 10 patients (59%) underwent complete surgical resection. In the evaluation of the surgical specimens, 14 patients (82%) had residual viable tumors after IC. The response to IC was significantly associated with the 3‐year LCR (CR/PR vs. SD/PD: 100% vs. 33%, P = 0.0014). In patients with good response to chemotherapy, the DPE group had a significantly better 3‐year LCR compared with that of the CRT group (DPE group vs. CRT group, 100% vs. 44%, P = 0.018). However, the treatment modalities were not associated with OS (DPE group vs. CRT group, 65% vs. 57%: P = 0.98). The recurrence patterns differed according to treatments, and distant metastases were more frequent in the DPE group. DPE may impact local control of localized nonmetastatic adult head and neck RMS. Poor response to IC is a risk factor for local recurrence.

Abstract
BACKGROUND AND STUDY AIMS Early detection of superficial pharyngeal squamous cell carcinoma (SPSCC) using narrow-band imaging as well as the increasing use of ER for gastrointestinal cancers may increase the number of ER for SPSCC. The aims of this study were to clarify the feasibility of ER for SPSCC and its long-term outcomes. PATIENTS AND METHODS In total, 84 patients with 115 lesions were treated by endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) between March 2004 and August 2012. We retrospectively assessed the en bloc and R0 resection rates, complications, lymph node metastasis (LNM), local recurrence, metachronous pharyngeal and esophageal SCC, 5-year overall and cause-specific survival rates. RESULTS Higher proportions of en bloc and R0 resection were achieved with ESD compared to EMR (en bloc 100 % vs. 60 %, P < 0.001; R0 59 % vs. 26 %, P < 0.005). There were no significant complications in both groups. None of the patients died from primary SPSCC during the median follow-up of 34 months (range, 3 - 115). LNM occurred in three patients and local recurrence was detected in seven patients (8.3 %) with eight lesions. Tumor thickness over 1000 μm (P < 0.005) and positive or inconclusive horizontal margins (P < 0.05) were significant risk factors for LNM and local recurrence, respectively. Twelve patients died because of co-existing clinical conditions. The 5-year overall and cause-specific survival rates were 80.7 % and 100 %, respectively. CONCLUSIONS ER for SPSCC is a feasible treatment with promising results. Tumor thickness over 1000 μm is a significant risk factor for LNM and positive or inconclusive horizontal margin is a risk factor for local recurrence.

Abstract
BACKGROUND This study evaluated cervical lymph node metastases at level IIb in cases of hypopharyngeal cancer and analyzed the possibility of preservation of level IIb during neck dissection. METHODS In total, 34 patients (51 neck sides) with hypopharyngeal cancer that underwent neck dissection from April 2008 to April 2011 were retrospectively analyzed. We evaluated the distribution of metastatic lymph nodes at various levels (particularly level IIb) in cases treated with therapeutic neck dissection and elective neck dissection. RESULTS The incidence of metastases in level IIb was 13.3% (4 of 30 patients) for therapeutic neck dissection and 0% (0 of 21 patients) for elective neck dissection. All the level IIb metastases were found on the ipsilateral side in the cases treated with therapeutic neck dissection. CONCLUSIONS The results suggest that preservation of level IIb during neck dissection was possible in N0 cases of hypopharyngeal cancer.

Abstract
BACKGROUND The objective of this study was to evaluate the efficacy and safety of minimally invasive transoral en bloc resection of superficial pharyngeal and laryngeal cancers. METHODS Forty-one superficial lesions (from 35 patients) were resected transorally under a surgical microscope using a monopolar cautery. Quality of life (QOL) was assessed using a questionnaire European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Cancer Module (EORTC QLQ-H&N35) 1 year after the surgery. RESULTS Twenty-eight hypopharyngeal, 5 oropharyngeal, and 8 laryngeal cancers were operated on using this method. The surgical field was widely exposed with a wide-caliber scope or extending laryngoscope. A bimanual procedure under a surgical microscope enabled us to achieve en bloc resection. The local control rate was 98%. No postoperative dyspnea or dysphagia was observed. Postoperative QOL scores were favorable. CONCLUSIONS Our transoral en bloc resection technique can be easily adopted, and it effectively maintained QOL after treatment.

Abstract
CONCLUSIONS We successfully reduced the incidence of pharyngocutaneous fistulas (PCFs) in high-risk patients undergoing surgery by using pectoralis major myocutaneous flaps (PMMCFs) and deltopectoral flaps (DPFs) to cover suture lines. OBJECTIVES We used coverage of suture lines with PMMCFs and DPFs in patients with high risk of PCFs undergoing total laryngectomy (TL) or total pharyngolaryngectomy (TPL) to determine whether coverage of suture lines during salvage surgery can reduce the incidence of PCFs. METHODS This retrospective study was based on a review of 52 patients who underwent salvage TL or TPL between 2001 and 2011; we have been using PMMCFs or DPFs during salvage surgery since 2008. Details of postoperative complications including PCFs were analyzed. RESULTS The incidence rate of PCF was lower in the flap group (7.7%) than that in the non-flap group (30.1%). No carotid ruptures were observed in the flap group (0%) as contrasted with patients in the non-flap group (7.7%).

Abstract
Objective: Evaluate the efficacy and safety of the transoral en bloc resection of superficial pharyngeal and laryngeal cancers. Transoral tumor resection is one option of minimally invasive surgery. Method: From 2008 to 2010, 34 lesions (from 31 patients) were resected transorally under microscope with monopolar cautery. Results: Twenty-four hypopharyngeal, 4 oropharyngeal, and 6 laryngeal cancers were operated on using this method. Operation field was widely exposed with wide caliber scope or extending laryngoscope. Bimanual procedure under microscope enabled us to achieve en bloc resection. Radical neck dissection was done simultaneously in one case. Local control rate was 97%. No postoperative dyspnea or dysphagia was observed. Two-thirds of the patients had no symptoms, which were detected by screening of the esophageal cancer patients. Narrow Band Imaging (NBI) system was very useful for detection of the superficial lesions. Conclusion: Transoral robotic surgery is now applied for minimally invasive surgery, which is not applicable yet in Japan. Our technique of en bloc resection can be easily introduced and was effective in maintaining the quality of life after treatment.

Abstract
A confocal laser microscope system was developed for the measurement of radiophotoluminescence (RPL) photons emitted from a minute alpha-ray-irradiated area in an RPL glass dosemeter. The system was composed mainly of an inverted-type microscope, an ultraviolet laser, an XY movable stage and photon-counting circuits. The photon-counting circuits were effective in the reduction of the background noise level in the measurement of RPL photons. The performance of this microscope system was examined by the observation of standard RPL glass samples irradiated using (241)Am alpha rays. The spatial resolution of this system was ∼ 3 μm, and with regard to the sensitivity of this system, a hit of more than four to five alpha rays in unit area produced enough amount of RPL photons to construct the image.

Abstract
New radiophotoluminescence (RPL) phosphate glass containing (6)Li was successfully made from the powder of NaPO(3), Al(PO(3))(3), LiOH, HPO(3) and AgCl. The ternary diagram of NaPO(3)-Al(PO(3))(3)-LiPO(3) has clarified the region where satisfactory RPL characteristics of the glass are kept up. The synthesised phosphate glass indicated good RPL characteristics on the condition that the content of LiPO(3) was below 10 wt%. Gamma-ray irradiation experiments showed that the newly synthesised phosphate glass had satisfactory linearity and wide dynamic range in dose measurement and low variation in sensitivity. It was confirmed from thermal neutron irradiation experiments that a pair of the newly synthesised phosphate glass containing enriched (6)Li and (7)Li, or (n)Li and enriched (7)Li could be effectively used for the evaluation of thermal neutron dosimetry.
