RESUMO
Objectives: The aim of present study was to evaluate the clinical efficacy of hyperbaric oxygen therapy (HBOT) as a primary therapy combined with standard systemic corticosteroid treatment for sudden sensorineural hearing loss (SSNHL) compared to treatment without the use of HBOT (non-HBOT) through clinical data and advanced analytical approaches. Study Design: Case-control study. Methods: Conducted across three Japanese medical centers involving 298 SSNHL patients diagnosed between 2020 and 2023. Inclusion criteria encompassed first onset and treatment, WHO grade 3 or 4 initial hearing impairment, receipt of systemic corticosteroid therapy within 14 days of symptom onset, and initiation of HBOT within the same timeframe for the case group. The primary outcome measure was the difference in hearing improvement (mean hearing level in decibels, dB) between the two groups, assessed by pure-tone audiometry at baseline and 3 months post-treatment, using the inverse probability of treatment weighting (IPTW) method adjusted for covariate differences. Results: The study included 67 patients in the HBOT group and 68 in the non-HBOT group. The HBOT group exhibited significantly greater hearing improvement (IPTW-adjusted difference: 7.6 dB, 95% CI 0.4-14.7; p = 0.038). Patients without vertigo in the HBOT group demonstrated substantial hearing improvement (11.5 dB, 95% CI 2.3-20.6; p = 0.014), whereas those with vertigo showed no significant improvement (-1.8 dB, 95% CI -11.8-8.3; p = 0.729). The HBOT group also had a significantly higher association with complete recovery (IPTW-adjusted odds ratio: 2.57, 95% CI 1.13-5.85; p = 0.025). Conclusion: In SSHNL, HBOT combination therapy yielded slightly but significantly improved hearing outcomes compared to non-HBOT treatment. Level of Evidence: 4.
RESUMO
BACKGROUND: Pembrolizumab alone or combined with chemotherapy is the standard of care for first-line treatment of patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) with positive programmed death-ligand 1 combined positive scores. However, data on second-line chemotherapy following pembrolizumab are scarce. METHODS: A single-center, retrospective study was conducted to determine the efficacies of pembrolizumab and pembrolizumab plus chemotherapy as first-line treatments and the efficacy of second-line chemotherapy for patients with R/M HNSCC who were refractory or intolerant to first-line treatment. RESULTS: Fifty-four patients were treated with pembrolizumab, and 29 received second-line therapy, with 27 opting for cetuximab-containing regimens. The median progression-free survival (PFS), overall survival (OS), and PFS on next-line therapy for first-line treatment were 4.7 (95% confidence interval [CI], 2.1-8.7), 22.1 (95% CI, 12.6-not reached), and 15.6 months (95% CI, 9.7-not reached) in the pembrolizumab group and 5.4 (95% CI, 3.3-6.8), 15.8 (95% CI, 8.6-not reached), and 13.7 months (95% CI, 8.1-not reached) in the pembrolizumab plus chemotherapy group, respectively. The overall response rate and median PFS for second-line treatment were 48.3% (95% CI, 30.4-67.0) and 6.1 months (95% CI, 2.30-8.84). The median OS for patients who received second-line treatment was 18.4 months, which was superior to the median OS of 6.0 months for patients who received the best supportive care (log-rank p = 0.10). CONCLUSION: This study indicates that cetuximab-containing second-line chemotherapy can improve outcomes in R/M HNSCC, even after first-line therapy failure or intolerance.

BACKGROUND/AIM: Although gemcitabine plus cisplatin (GC) prolongs survival in patients with recurrent or metastatic nasopharyngeal carcinoma (R/M NPC) compared with fluorouracil plus cisplatin, no study has evaluated the efficacy and safety of GC in nonendemic regions, including Japan, yet. Therefore, we assessed the safety and efficacy of GC in Japanese patients with R/M NPC. PATIENTS AND METHODS: We retrospectively reviewed patients with R/M NPC who received GC treatment at the Aichi Cancer Center Hospital from January 2017 to March 2020. The main eligibility criteria were histologically confirmed NPC, Eastern Cooperative Oncology Group performance status (ECOG PS) of 0-2, and locally recurrent disease unsuitable for local treatment or metastatic disease. The regimen was administered every 3 weeks (gemcitabine, 1,000 mg/m2 on days 1 and 8; cisplatin, 80 mg/m2 on day 1). RESULTS: Fourteen patients (median age, 58 years) were included in the study. Two patients had an ECOG PS of 2 and 11 exhibited nonkeratinizing histology. Of the eight patients with measurable lesions, one exhibited complete response and seven exhibited partial response, with an objective response rate of 75%. Median progression-free survival and overall survival were 7.7 and 24.2 months, respectively. Common grade 3 or 4 adverse events included neutropenia (64%), thrombocytopenia (14%), and febrile neutropenia (14%). The median relative dose intensity of gemcitabine and cisplatin was 62% and 60%, respectively. No treatment-related deaths occurred. CONCLUSION: The GC regimen demonstrates promising activity and is tolerable in Japanese patients with R/M NPC.

BACKGROUND: It is unclear witch regimen is optimal as salvage chemotherapy (SCT) after immune checkpoint inhibitor (ICI) monotherapy for recurrent or metastatic head and neck cancer (RM-HNC). METHODS: This study enrolled 109 patients. Overall survival (OS) and progression-free survival 2 (PFS2) were compared between patients stratified by SCT regimen. RESULTS: Of the 109 patients, 55 underwent SCT after the failure of ICI monotherapy. The OS of these 55 patients was longer than that of patients who did not undergo SCT. The OS and PFS2 were similar between patients treated with paclitaxel (PTX) and cetuximab (Cmab) combination and those treated with PTX monotherapy. The occurrence of irAEs did not impact PFS2 nor OS. CONCLUSIONS: SCT can improve the survival outcomes of patients with RM-HNC. In addition to PTX and Cmab, PTX monotherapy is also considered an effective SCT regimen. SCT is effective regardless of the presence or absence of irAEs.

Fluorouracil (FU) exerts its antitumor activity by inhibiting folate-mediated one-carbon metabolism. Evidence that folate may play a role in the carcinogenic process via folate-mediated one-carbon metabolism has given rise to the hypothesis that pre-diagnostic folate intake may induce heterogeneous chemosensitivity to FU-containing induction chemotherapy (IC) in head and neck cancer. To assess this hypothesis, we conducted a cohort study to investigate whether the association between prediagnostic dietary folate intake and cancer survival differed between treatment regimens with and without FU-containing IC in 504 cases of locally advanced (stage III/IV) HNSCC, using an epidemiologic database combined with clinical data. In total, 240 patients were treated with FU-containing IC followed by definitive treatment, and 264 patients were treated with definitive treatment alone. Definitive treatment is defined as (1) the surgical excision of a tumor with clear margins, with or without neck lymph node dissection; or (2) radiotherapy with or without chemotherapy. In the overall cohort of the FU-containing IC group, a higher folate intake was significantly associated with better overall survival (adjusted hazard ratios (HRs) for the highest compared to the lowest folate tertiles (HRT3-T1) = 0.42, 95%CI, 0.25-0.76, Ptrend = 0.003). Conversely, no apparent association between prediagnostic folate intake and survival was observed with definitive treatment alone (HRT3-T1: 0.83, 95%CI, 0.49-1.42, Ptrend = 0.491)). A consideration of the cumulative dose of FU-containing IC showed that the survival impact of prediagnostic folate intake differed statistically significantly by treatment regimen (Pinteraction = 0.012). In conclusion, an association between prediagnostic folate intake and HNSCC survival significantly differed by FU-containing IC. This finding indicates that in the carcinogenic process, folate status causes HNSCC to be heterogenous in terms of one-carbon metabolism.
RESUMO
BACKGROUND/AIM: The Warburg effect of cancer has been applied to detect various carcinomas though the 18F-fluorodeoxyglucose (18F-FDG) uptake on positron emission tomography with computed tomography (PET/CT). 18F-FDG-PET/CT in lung cancer predicted the mutation status of epidermoid growth factor receptor (EGFR). This study aimed to investigate whether 18F-FDG uptake parameters were significantly related to EGFR mutation status in patients with sinonasal tract squamous cell carcinoma (STSCC). PATIENTS AND METHODS: Twenty-nine tumor specimens of primary STSCC from patients with definitive treatment were collected. RESULTS: The 18F-FDG uptake from primary tumors was not different between mutant- and wild-status of EGFR on either Mann-Whitney U-test or the receiver operating curve. A metabolic tumor volume of ≥25 with the minimum p-value from the log-rank test for STSCC-specific survival was associated with a significantly shorter STSCC-specific, disease-free, local recurrence-free survival on the univariate and multivariate analyses adjusted for the clinical stage, treatment, and EGFR status. CONCLUSION: 18F-FDG-PET/CT did not predict mutation of the EGFR status in STSCC.

This sentinel node (SN) biopsy trial aimed to assess its effectiveness in identifying predictive factors of micrometastases and to determine whether elective neck dissection is necessary in oral squamous cell carcinoma. This retrospective study included 55 patients from three previous trials, with positive SNs. The relationship between the sizes of the metastatic focus and metastasis in non-sentinel node (NSN) was investigated. Four of the 55 largest metastatic focus were isolated tumor cells, and the remaining 51 were ranged from 0.2 to 15 mm, with a median of 2.6 mm. The difference of prevalence between 46 negative- and 9 positive-NSN was statistically significant with regard to age, long diameter of primary site and number of cases with regional recurrence. In comparing the size of largest metastatic focus dividing the number of positive SN, with metastaic focus range of < 3.0 mm in one-positive SN group, there were 18 (33%) negative-NSN and no positive-NSN. Regarding prognosis, 3-year overall survival rate of this group (n = 18) and other (n = 37) were 94% and 73% (p = 0.04), and 3-year recurrence free survival rate of this group and other were 94% and 51% (p = 0.03), respectively. Absolutely a further prospective clinical trial would be needed, micrometastases may be defined as solitary SN metastasis with < 3.0 mm of metastatic focus, and approximately 33% of neck dissections could be avoided using these criteria.

BACKGROUND: Transoral robotic surgery (TORS) for tongue base lesions located above the operative field is predominantly an upward procedure, which makes surgery difficult. METHODS: To illustrate our technique for this procedure, we report the case of an 82-year-old male with a p16-negative oropharyngeal carcinoma of the tongue base who underwent TORS. The field of view was turned upside down, and the operation switched the typical left- and right-arm functions. The daVinci Xi was docked, the 0° endoscope was rotated 180°, and the first arm was switched to the right hand and the third arm to the left hand. RESULTS: Although the lesion extended from the tongue base to the soft palate and mobile tongue, the planned resection line was followed. CONCLUSIONS: This technique improves operability by allowing downward manipulation and preventing the left and right arms from crossing. Further validation of the technique's effectiveness and safety is needed.

BACKGROUND: Photoimmunotherapy (PIT) is a new cancer treatment based on a different mechanism from conventional treatments that combines the administration of a photoabsorber and laser illumination. PIT has two characteristics: a high selectivity of target cells and the possibility of effects beyond the illuminated area. It is thus a potentially effective treatment for a wide variety of cancers. CASE PRESENTATION: We herein report a patient with oropharyngeal squamous cell carcinoma with superficial cervical lymph node recurrence. Intraoperative ultrasound confirmed the localization of the lesion and major vessels near the tumor. We punctured the tumor with catheters of laser illumination under ultrasound guidance. Laser illumination was able to be performed safely without causing serious adverse events, and the effect on the illuminated site was fully exhibited. CONCLUSIONS: Ultrasound allows for the intraoperative monitoring of each localized area and the puncture status easily in real-time. Accurate utilization of ultrasound is extremely important in PIT.
RESUMO
This study aimed to investigate the relationship between the lymph node ratio (LNR) and survival results of patients with head and neck squamous cell carcinoma (HNSCC) reconstructed by a submental artery flap (SMAF) to limit tumor size. This study retrospectively recruited 49 patients with HNSCC who underwent both primary resection and neck dissection with SMAF reconstruction. The LNR was the ratio of the number of metastatic lymph nodes to the sum number of examined lymph nodes. A LNR of 0.04 was the best cut-off value for HNSCC-specific death on receiver operating curve analysis. Patients with LNRs > 0.04 were univariately related to cancer-specific, disease-free, distant metastasis-free, and locoregional recurrence-free survival than those with LNRs ≤ 0.04 by log-rank test. In a Cox's proportional hazards model with hazard ratio (HR) and 95% confidence interval (CI) adjusting for pathological stage, extranodal extension and or surgical margins, the LNR (>0.04/≤0.04) predicted multivariate shorter cancer-specific (HR = 9.24, 95% CI = 1.49−176), disease-free (HR = 3.44, 95% CI = 1.23−10.3), and distant metastasis-free (HR = 9.76, 95% CI = 1.57−187) survival. In conclusion, LNR for patients of HNSCC with SMAF reconstruction for limited tumor size was a prognostic factor for survival outcomes.
RESUMO
Human papillomavirus (HPV)-associated oropharyngeal cancer has a better prognosis than other head and neck cancers. However, rates of recurrence and metastasis are similar and the prognosis of recurrent or metastatic HPV-associated oropharyngeal cancer is poor. Near-infrared photoimmunotherapy (NIR-PIT) is a treatment involving administration of a photosensitizer (IRDye®700DX) conjugated to a monoclonal antibody followed by activation with near-infrared light illumination. It is a highly tumor-specific therapy with minimal toxicity in normal tissues. Moreover, NIR-PIT is expected to have not only direct effects on a treated lesion but also immune responses on untreated distant lesions. NIR-PIT with cetuximab-IR700 (AlluminoxTM) has been in routine clinical use since January 2021 for unresectable locally advanced or locally recurrent head and neck cancer in patients that have previously undergone radiotherapy in Japan. NIR-PIT for head and neck cancer (HN-PIT) is expected to provide a curative treatment option for the locoregional recurrent or metastatic disease after radiotherapy and surgery. This article reviews the mechanism underlying the effect of NIR-PIT and recent clinical trials of NIR-PIT for head and neck cancers, treatment-specific adverse events, combination treatment with immune checkpoint inhibitors, illumination approach and posttreatment quality of life, and provides a case of series of two patients who receive NIR-PIT for oropharyngeal cancer at our institution.
RESUMO
BACKGROUND: During the COVID-19 pandemic, pedicle flaps instead of free flap transfer were recommended for head and neck reconstruction to reduce infection risk. Boron neutron-capture therapy in Japan was clinically approved in 2020 as a salvage radiotherapy for recurrent head and neck cancer following chemoradiotherapy. The efficacy and safety of salvage surgery following boron neutron-capture therapy remain unclear. CASE REPORT: We describe a 57-year-old male with crT4aN0M0 oral cancer after three different forms of radiotherapy including boron neutron-capture therapy, treated by salvage partial maxillectomy with both buccal fat pad and nasoseptal flaps. His postsurgical course was successful, without tracheostomy, and he had no Clavien- Dindo grade 3 or 4 complications. The pathological diagnosis was T4a squamous cell carcinoma with a negative surgical margin. No recurrence or metastasis had occurred at 113 days postoperatively. No opioid consumption was needed postoperatively. CONCLUSION: Pathological negative margins were achieved in this case and there were no severe complications. Further accrual of cases salvage surgery following boron neutron-capture therapy is required to clarify treatment strategies for recurrent head and neck cancer.

BACKGROUND: High uptake of F18-fluorodeoxyglucose parameters for glucose metabolism is related to shorter survival in sinonasal tract cancer with various histological classifications. We investigated whether F18-fluorodeoxyglucose uptake parameters are associated with survival outcomes for patients with only squamous cell carcinoma (SCC) in the sinonasal tract that are treated either with surgery or nonsurgery. METHODS: We retrospectively observed F18-fluorodeoxyglucose uptake parameters on positron emission tomography with computed tomography for the primary tumour of SCC in 39 patients. Log-rank test or a Cox regression model with 95% confidence interval (95%CI) and hazard ratio (HR) were used for monovariable or multivariable analysis, respectively. We determined cut-off values of the F18-fluorodeoxyglucose uptake parameters using the lowest p value for monovariable sinonasal tract cancer-specific survival analysis. RESULTS: Monovariable analysis showed that patients with metabolic tumour volume (MTV) ≥ 21.8 had a shorter cancer-specific, disease-free and local recurrence-free survival than those with MTV < 21.8. After adjusting for age, gender, clinical stage and treatment group in the multivariable analysis, MTV (≥21.8/<21.8) was related to shorter cancer-specific (HR: 3.69, 95%CI: 1.17-12.0), disease-free (HR: 3.38, 95%CI: 1.19-9.71) and local recurrence-free (HR: 5.42, 95%CI: 1.59-20.3) survivals. CONCLUSIONS: MTV as advances in diagnostics of sinonasal tract SCC is a predictor.
RESUMO
OBJECTIVE: To present a new procedure for inserting a secondary voice prosthesis from the inside to the outside, which improves on the method previously reported by Fukuhara et al. METHODS: A flexible nasopharyngoscope was used to puncture pharynx (or transplanted jejunum) from the inside to the outside. In this method, it was possible to use the PROVOX® VegaTM Puncture Set as it is used for the placement of the voice prosthesis. RESULTS: We were able to place the PROVOX® VegaTM in all cases we experienced. Most of the cases had a history of radiation therapy. The time required for surgery ranged from 11-59 minutes (mean: 29 minutes) and there was no measurable amount of bleeding. CONCLUSION: This new method using the PROVOX® VegaTM Puncture Set, which is designed for the original purpose of voice prosthesis implantation, was therefore found to be safe and effective.

Primary squamous cell carcinoma of the thyroid (PSCCT) is a rare disease with a poor prognosis. Because of its rarity, there is no established therapeutic regimen in unresectable cases. We report a case of PSCCT treated with weekly paclitaxel (wPTX) for more than 2 years. A 59-year-old woman presented to our hospital with a progressively enlarging neck mass. CT and MRI scans showed a tumor arising from the right lobe of the thyroid, invading the esophagus and trachea, as well as partially surrounding and invading the right common carotid artery. It was deemed unresectable. Biopsy revealed poorly differentiated squamous cell carcinoma. wPTX therapy was initiated. The patient achieved a partial response and is still undergoing treatment 28 months later. Adverse events included grade 3 neutropenia and grade 2 peripheral sensory neuropathy, which were manageable. Long-term wPTX therapy has been effective in this case of unresectable PSCCT.

BACKGROUND: We investigate whether pathological continuous variables of lymph nodes were related with survival results of carcinomas of minor salivary gland carcinoma in head and neck. METHODS: Forty-four cases with minor salivary gland carcinoma who underwent both primary resection and neck dissection were retrospectively enrolled. The pathological continuous variables were evaluated by the number of positive lymph nodes, lymph node ratio, and log odds of positive lymph nodes. Receiver operating curve analysis was used for the cut-off values of the carcinoma-specific death. Log-rank test and Cox's proportional hazards model were used for uni-/multi-variate survival analyses adjusting for pathological stage, respectively. RESULTS: Lymph node ratio = 0.05 as well as log odds of positive lymph nodes = - 2.73 predicted the carcinoma-specific death. Both lymph node ratio and log odds of positive lymph nodes were significantly related with survival outcomes by the univariate analysis. Lymph node ratio ≥ 0.05 was associated with shorter disease-specific (hazard ratio = 7.90, 95% confidence interval = 1.54-57.1), disease-free (hazard ratio = 4.15, 95% confidence interval = 1.48-11.2) and overall (hazard ratio = 4.84, 95% confidence interval = 1.05-24.8) survival in the multivariate analysis. CONCLUSION: A higher lymph node ratio of minor salivary gland carcinoma is a predictor of shorter survival results.

ABSTRACT: The purpose of the present study is to investigate whether the 18F-fluorodeoxyglucose (18F-FDG) uptake parameter is related to survival outcomes for patients with clinical T3-T4a laryngeal cancer with various definitive treatments including total laryngectomy (TL). Parameters of 18F-FDG uptake in the primary tumors of 46 cases which were assessed by positron emission tomography with computed tomography were enrolled in the present observation study. Monovariate or multivariate survival analyses were performed with log-rank test or Cox regression model, with the hazard ratio (HR) and 95% confidence interval (CI), respectively. Cutoff values of the 18F-FDG uptake parameters were determined by the lowest P-value for monovariate overall survival. In the monovariate analysis, both metabolic tumor volume ≥13.1 and total lesion glycolysis (TLG) ≥46.5 were significantly associated with shorter overall survival, and TLG ≥46.5 was also related to a reduction in distant metastasis-free survival. In the multivariate analysis adjusting for clinical T classification (cT4/cT3) and treatment group (TL/non-TL), TLG (≥46.5/<46.5) was associated with both poorer overall (HR: 3.16, 95% CI: 1.10-9.49) and distant metastasis-free (HR: 8.91, 95% CI: 1.93-62.6) survival. In conclusion, TLG is a predictor for survival in laryngeal cancer.

BACKGROUND: During the coronavirus disease 2019 (COVID19) pandemic, pedicle flaps (instead of free flaps) were recommended for reconstruction following wide resection for patients with head and neck cancer, in order to reduce the use of medical resources. Currently, there are no established treatment guidelines for patients with head and neck cancer with synchronous esophageal cancer. CASE REPORT: We present a 68-year-old male with cT4aN2cM0 oral floor and synchronous cT1bN1M0 esophageal cancers who had defective reconstruction following oral tumor resection before esophagectomy during the pandemic. At the initial surgery, the oral resected defect was reconstructed using supraclavicular artery flap. The subsequent esophagectomy was reconstructed by gastric tube reconstruction. Both postoperative courses were successful, without the need for postoperative ventilator use. The days from initial or second surgery to discharge were 14 or 16 days, respectively. CONCLUSION: This case had achieved negative surgical margins and recovered oral intake with tracheostomy decannulation. Further case accruement using supraclavicular artery flap is required for patients with head and neck cancer and synchronous esophageal cancer.

BACKGROUND: Until the emergence of immune checkpoint inhibitors, the EXTREME regimen comprising platinum-based chemotherapy plus cetuximab was the standard of care for recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC). Recent reports suggest the usefulness of regimens including taxanes in combination with cetuximab as treatment options for R/M HNSCC patients with contraindications for platinum. However, comparisons of weekly paclitaxel plus cetuximab (wPTX-Cmab) to the EXTREME regimen are limited. MATERIALS AND METHODS: We compared the clinical impact of wPTX-Cmab to EXTREME as first line treatment for R/M HNSCC in Aichi Cancer Center Hospital. The primary outcome was overall survival (OS) and secondary outcomes were progression-free survival (PFS), overall response rate (ORR) and disease control rate (DCR). Propensity score-adjusted Cox proportional hazard models were used to determine hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: From 2012 to 2018, 77 patients, including 55 treated with EXTREME and 22 refractory or intolerant to platinum treated with wPTX-Cmab, were analyzed. wPTX-Cmab was comparable to EXTREME on OS [adjusted HR 0.82 (95% CI 0.39-1.48)], PFS [adjusted HR 0.90 (95% CI 0.49-1.65)], ORR [wPTX-Cmab 34.7% (12-43), EXTREME 30.9% (18-43), p = 0.877] and DCR [wPTX-Cmab 72.7% (52-92), EXTREME 65.4% (52-78), p = 0.337]. Survival trends remained similar after stratification by platinum-refractory or intolerance status. Disease control with wPTX-Cmab was significantly associated with better OS [adjusted HR 0.18 (0.05-0.57)]. CONCLUSION: wPTX-Cmab may be a suitable treatment option for R/M HNSCC patients with contraindications for platinum.

The objective of our study was to clarify the clinical features of EGFR-mutated sinonasal squamous cell carcinoma (SNSCC) and human papilloma virus (HPV)-related SNSCC. Patients with SNSCC treated from April 2008 to June 2019 at our institution were retrospectively reviewed. We examined EGFR mutation and HPV status for all patients. Main outcomes were overall survival, recurrence, and outcome of each treatment modality. A total of 85 patients with SNSCC were enrolled in this study. EGFR mutations and HPV DNA were detected in 24 (28%) and 7 (8%) patients, respectively. Patients with EGFR-mutated SNSCC showed a worse overall survival (OS) than those with EGFR wild-type in the multivariate analysis (p = 0.037). No death was observed in HPV-positive SNSCC. The cumulative incidence of local recurrence was significantly higher in EGFR mutant than EGFR wild-type tumors (p = 0.03). In patients with EGFR mutations, treatment with induction chemotherapy significantly improved OS (p = 0.01). EGFR-mutated SNSCC have a high-risk feature for recurrence and requires intensive attention for treatment and observation. A new treatment approach, such as EGFR tyrosine kinase inhibitors, may be needed.
