A Case of Huge Cutaneous Verrucous Carcinoma of the Neck.

Verrucous carcinoma (VC) is a rare subtype of squamous cell carcinoma. VC commonly occurs in the mucosa, but rarely occurs in the skin. The treatment for VC is surgical removal of the tumor. Because lymph node metastasis of VC is rare, the indications for prophylactic neck dissection for cutaneous VC of the neck are controversial. Here, we present the case of a 68-year-old man with a huge cutaneous VC of the neck and the long-term clinical course. The tumor occupied the entire right cervical skin, with suspected lymph node metastasis in the affected neck. Tumor resection and neck lymph node dissection were performed. Pathological examination revealed cutaneous VC with invasion to the adjacent tissues and no lymph node metastasis. Cutaneous VC of the neck is likely to grow locally without regional lymph node metastasis regardless of the long-term course and the size of the tumor.

Indications for and extent of elective neck dissection for lymph node metastasis from external auditory canal carcinoma.

OBJECTIVES: We aim to clarify the frequency of lymph node metastasis of external auditory canal (EAC) carcinoma, including susceptible locations, adequate extent of elective neck dissection, and the relationship between the tumor infiltration site and lymph node metastasis. PATIENTS AND METHODS: From 2003 to 2018, 63 patients with EAC carcinoma at Tokyo Medical and Dental University Hospital were enrolled in this study. The T and N stages, locations of clinically positive lymph nodes, prognoses, and anatomic site of tumor infiltration were analyzed after treatment. RESULTS: Clinically positive lymph node metastasis (cN+) was detected in 18 patients (28.6%), consisting of T1, T2, T3, and T4 disease in 1 (6%), 2 (22%), 8 (38%), and 7 (41%) patients, respectively. The metastatic locations were at level II in 10 patients, parotid gland nodes in 7, preauricular nodes in 5, level Ib in 3, level Va in 3, level III in 1, and superficial cervical nodes in 1. Neck recurrence was determined in two of 45 patients with clinically negative lymph nodes (cN0), with the metastatic locations being levels II, Ib, and III. Among 18 cN+ cases, neck recurrence was noted in 2 of 9 patients who underwent neck dissection. Neck lesions were found to be manageable in all five patients who underwent docetaxel, cisplatin, 5-fluorouracil, and radiation therapy (TPF-RT). No relationship was noted between the tumor infiltration site and lymph node metastasis among T3/4 canrcinoma patients. CONCLUSIONS: Elective neck dissection could be indicated only in T3/4 patients with free flap reconstruction. Levels Ib to III are considered appropriate for elective neck dissection in cN0 cases. Levels Ib to III and Va indicated favorable sites, even in cases with metastasis in the parotid gland or preauricular area. Furthermore, TPF-RT could be a useful option even in cN+ cases.

Endoscopy-Aided Combined Intraoral and Cervical Approach for a Huge Parapharyngeal Benign Tumor.

We introduce here our surgical approach for the removal of a huge parapharyngeal tumor in 3 cases. Surgery was done under general anesthesia using transnasal intubation. Transoral manipulation was performed first. Using a tongue retractor and an angle widener, a wide surgical field was provided. Incision was made on the palate around the tumor. Tumor was separated from the surrounding tissue, preserving the tumor capsule. Then, a 5-cm small skin incision was made. Both parotid and submandibular glands were pushed upward, and the parapharyngeal space was opened. The tumor was also separated from the surrounding tissue. These manipulations were done under endoscopic observation. Finally, the tumor was pushed laterally and safely removed intraorally. After removal of the tumor, the wounds were closed, and vacuum drainage was settled for a few days. No apparent problems, such as malocclusion and facial palsy, occurred, and the patients were free from disease for more than 10 years. For the removal of a large parapharyngeal tumor, the mandibular swing approach is usually used; however, this approach is invasive, and certain sequelae, such as facial wound and malocclusion, may occur. Our technique enables the safe and less invasive removal of such a huge parapharyngeal benign lesion.

Otitis Media With Effusion Caused by a Parapharyngeal Tumor Showing Normal Nasopharyngeal Findings.

The objective of this study is to evaluate otitis media with effusion (OME) among patients with parapharyngeal tumor. We have experienced 82 parapharyngeal tumor cases and encountered 14 patients complaining of hearing loss due to OME as the initial symptom. These patients showed normal nasopharyngeal findings and the presence of tumor had been detected long time after the beginning of their hearing symptoms (4 months to 13 years: median 2.5 years). Six patients had undergone ventilation tube insertion on the affected ear, which may lead to delay in diagnosis. Pathological examination was performed in 76 of 82 patients. Among these 76 patients, 13 showed OME. Seven patients had malignant lesions, whereas 6 had benign lesions. Therefore, malignant lesions are prone to occur with OME and its relative risk was 2.26 (95% confidence intervals, 1.16-4.42). This difference was statistically significant (P = .044, Fisher test). Otitis media with effusion is a very common disease and is well-known as a primary symptom of nasopharyngeal carcinoma. Therefore, nasopharyngeal observation is necessary for patients with intractable middle ear effusion. However, present 14 patients with OME showed normal nasopharyngeal findings and finally found after an imaging study. From our data, OME is an important but go-by symptom of parapharyngeal tumors. Imaging studies are potently useful for such patients with intractable OME.

Improving the Quality of Life of Patients With Severe Dysphagia by Surgically Closing the Larynx.

OBJECTIVES:: The aim of this study was to elucidate the utility of the Kano method with surgical closure of the larynx by cricoid cartilage removal in improving quality of life in patients with severe dysphagia and their caregivers. METHODS:: Nine patients with severe dysphagia who underwent the Kano method were evaluated for oral intake and activities of daily living using the functional oral intake scale and the Barthel index, respectively, as indices of quality of life. Additionally, nutritional status, inflammation, and postoperative complications were assessed. Furthermore, 7 family caregivers were queried regarding frequency of sputum suction, mood of family caregivers, and postoperative satisfaction. RESULTS:: Functional oral intake scale and Barthel index scores as well as inflammation improved significantly after surgery ( P < .05). There were no severe complications or other complications requiring surgical intervention. The frequency of sputum suction was reduced postoperatively ( P < .05). The mood of family caregivers was significantly improved and satisfaction level was high postoperatively. CONCLUSIONS:: Surgical closure of the larynx is an appropriate choice for patients with irreversible severe dysphagia and impaired articulation or vocal function because quality of life is improved for both patients and family caregivers and the satisfaction of family caregivers is sufficient.

Maxillary Swing Approach for Removal of Palatal Carcinoma: A Modified Procedure.

INTRODUCTION: We report a modification of the maxillary swing approach to remove a palatal tumor while preserving the anterior alveolar area. METHODS: Case report using clinical records. RESULTS: The patient was a 54-year-old male. TNM grade was T4bN0M0, and invasion to the base of the pterygoid process was seen. Two courses of induction chemotherapy were administered prior to the operation. Because there was no evidence of anterior maxillary invasion, the maxillary swing approach was chosen. The left anterior maxilla was cut and swung laterally, preserving the blood supply. After removal of the palatal tumor, the maxilla was repositioned and the defect was restored with an anterior lateral thigh flap. Postoperative course was typical, and facial appearance, speech, and masticatory function were satisfactory. CONCLUSIONS: This technique is particularly useful for preserving appearance as well as speech and mastication.

An Unusual Invasive Ectopic Thymoma in the Thyroid and Anterior Mediastinum.

An 81-year-old woman with a 2-year history of dysphagia detected a cervical mass. Computed tomography showed a thyroid tumor extending through the superior and anterior mediastinum. Analysis of an incisional biopsy specimen revealed a thymoma. Total resection of the thyroid and mediastinal tumor was performed. The thymoma invaded the anterior tracheal wall and left brachiocephalic vein. Pathologic examination revealed thymoma type B1 concomitant with B2 and B3 (World Health Organization classification), Masaoka IVb, and T3 N2 M0-IVb, with cervical lymph node metastasis. Clinicians must be cautious during radical operations for invasive ectopic thymomas.

A new method for selecting auricle positions in skull base reconstruction for temporal bone cancer.

OBJECTIVE: In advanced temporal bone carcinoma cases, we attempted to preserve as much of the auricle as possible from a cosmetic and functional perspective. Difficulties are associated with selecting an adequate position for reconstructed auricles intraoperatively. We improved the surgical procedure to achieve a good postoperative auricle position. METHODS: Nine patients were included in this study. All patients underwent subtotal removal of the temporal bone and resection of the external auditory canal while preserving most of the external ear, and lateral skull base reconstruction was performed with anterolateral thigh flaps. We invented a new device, the auricle localizer, to select the correct position for the replaced external ear. The head skin incision line and two points of three-point pin fixation were used as criteria, and a Kirschner wire was shaped as a basic line to match these criteria. Another Kirschner wire was shaped by wrapping it around the inferior edge of the external ear as the positioning line, and these two lines were then combined. To evaluate the postoperative auricle position, the auricle inclination angle was measured using head frontal cephalogram imaging. RESULTS: The external ear on the affected side clearly drooped postoperatively in nonlocalizer cases, whereas this was not obvious in localizer cases. Auricle inclination angles 1 year after surgery significantly differed between these two cases (P = 0.018). CONCLUSION: The surgical device, the auricle localizer, is useful for selecting intraoperative accurate auricle positions. The assessment index, the auricle inclination angle, is useful for quantitatively evaluating postoperative results. LEVEL OF EVIDENCE: 4 Laryngoscope, 2605-2610, 2018.

Patterns of stress coping and depression among patients with head and neck cancer: A Japanese cross-sectional study.

OBJECTIVE: Patients with head and neck cancer (HNC) experience many stressful problems with breathing, eating, swallowing, and/or speaking. The aim of this study was to (a) identify the clusters of HNC patients based on their stress coping strategies and (b) evaluate the differences in clinical data and depression among the identified HNC patients' coping clusters. METHODS: We conducted a single-center, cross-sectional study with self-completed questionnaires for patients with HNC between April and August 2013. We measured stress coping (an abbreviated version of the COPE Inventory: Brief COPE) and depression (the Japanese version of the Beck Depression Inventory-II: BDI-II). RESULTS: Of the 116 patients who completed all the questionnaires, 81 (69.8%) participants were 60 to 79 years old and 105 (90.5%) were men. Cluster analysis based on the standardized z score of Brief COPE showed that patients were classified into 3 clusters, labeled "dependent coping," "problem-focused coping," and "resigned coping." The ANOVA revealed that depression (BDI score) was significantly higher in the dependent-coping cluster compared with the problem-focused coping. CONCLUSIONS: This study indicates that patients with a dependent-coping pattern may account for the largest HNC population and are likely to suffer from depression. Dependent coping includes smoking, drinking, seeking support, or engaging self-distraction. In the future, we should develop psychological intervention programs focused on coping strategies and enhancement of the support system for patients with HNC.

Right dominance in the incidence of external auditory canal squamous cell carcinoma in the Japanese population: Does handedness affect carcinogenesis?

OBJECTIVES/HYPOTHESIS: To investigate the relationship between handedness and the incidence of squamous cell carcinoma in the external auditory canal (EACSCC). MATERIALS AND METHODS: Sixty-eight cases of EACSCC were enrolled in this study, and their affected side was checked. Handedness and ear-picking habits were also investigated in 34 EACSCC cases. Handedness was judged based on self-categorization, and the relationship between handedness and the affected side was investigated. RESULTS: Fifty-two cases occurred on the right side, and 16 cases occurred on the left side of patients with EACSCC. The incidence of laterality in EACSCC showed a statistically significant right dominance. Concerning handedness, 29 cases were right-handed, 4 cases were left-handed, and 1 case was ambidextrous. Twenty-seven out of the 29 right-handed cases and 1 ambidextrous case suffered from carcinoma on the right side, whereas 3 left-handed cases suffered from carcinoma on the left side. That is, most of the cases suffered from EACSCC on the same side as their handedness, and this tendency showed a statistically significant difference. Most of the patients with EACSCC experienced itching and habitual ear-picking in the affected side. CONCLUSION: Mechanical stimulations to the EAC, such as ear picking, may plausibly cause EACSCC. In Japan, ear picking, also called "mimikaki," is a popular habit and an established unique culture. Because ear picking requires delicate handling and manipulation, this tends to occur on the same side as the handedness in the Japanese population. This is the first report about the relationship between handedness and carcinogenesis. LEVEL OF EVIDENCE: N/A.

Japanese Clinical Practice Guideline for Head and Neck Cancer.

OBJECTIVE: The first revision of "Japanese Clinical Practice Guideline for Head and Neck Cancer" was made in 2013 by the clinical practice guideline committee of Japan Society for Head and Neck Cancer, in response to the revision of the TNM classification. METHODS: 34 CQs (Clinical Questions) were newly adopted to describe the diagnosis and treatment methods currently considered most appropriate, and offered recommendation grade made by the consensus of the committee. A comprehensive literature search was performed for studies published between 2001 and 2012 using PubMed. Qualified studies were analyzed and the results were evaluated, consolidated and codified by all the committee members. RESULTS: Elective neck dissection (ND) does contribute to improvement in survival and should be performed for patients with high-risk tongue cancer. At present, no research has clearly demonstrated the utility of superselective arterial infusion chemotherapy. However, depending on the site and stage of the cancer, combination with radiotherapy may be useful for preserving organ function or improving survival rate. Concurrent CDDP chemotherapy and adjuvant radiotherapy contributes to improvement of survival rate as an adjuvant therapy for advanced squamous cell carcinoma of the head and neck in patients at high risk of recurrence. The anti-EGFR antibody cetuximab (Cmab) has an additive effect with radiotherapy. However, the indication must be carefully considered since this treatment has not been compared with the standard treatment of chemoradiotherapy. Cmab has been shown to have an additive effect with chemotherapy (CDDP/5-FU) in patients with unresectable metastatic or recurrent cancer. Preoperative and postoperative oral care may reduce the risk of postoperative complications such as surgical wound infection and pneumonia in head and neck cancers. Rehabilitation soon after ND for cervical lymph node metastasis is recommended for maintaining and restoring shoulder function. CONCLUSIONS: In this article, we described most relevant guidelines and CQs for the diagnosis and treatment of head and neck cancer in Japan. These guidelines are not intended to govern therapies that are not shown here, but rather aim to be used as a guide in searching for the most appropriate treatment for individual patient.

Indication for and Limitation of the Facial Dismasking Flap Approach for Skull Base Surgery to Achieve the Best Esthetical and Functional Results.

BACKGROUND: The facial dismasking flap (FDF) approach to operations on the deep skull base region consists of a coronal incision and a circumpalpebral incision. This approach provides a wide surgical field for extirpation of deep extended craniofacial tumors without leaving any undesirable scars on the face. Therefore, the FDF approach can provide satisfactory esthetical and functional results. Meanwhile, in some cases, especially in patients with a history of skull base surgery or orbital extension, patients are not fully satisfied even when the FDF approach is used. In this study, we evaluated the indication for and limitation of the FDF approach. METHODS: We reviewed 26 patients who underwent the FDF approach for skull base surgery. The patients were 16 men and 10 women, and average age was 37 years. Of these patients, 21 were treated using a hemi-FDF approach, and the remaining 5 were subjected to a bilateral FDF approach. Patients were divided into 2 groups in this study: group A (11 patients), patients with no history of skull base surgery and orbital extension; and group B (15 patients), patients with a history of skull base surgery and/or orbital extension. RESULTS: There was no FDF loss or facial palsy in either group A or group B. In group A, there was no lagophthalmos or scar contracture of the eyelid. In group B, there were 5 cases (33%) of ectropion and lagophthalmos and 7 of eyelid scar contracture (46%). As for esthetical evaluation, group B showed a significantly higher rate of facial asymmetry than group A. Moreover, in group A, the total ratings for above average reached 90.9%, whereas in group B, nearly half of the patients (48.9%) gave ratings of fair and poor. CONCLUSIONS: The FDF approach could be a good option for skull base surgery. In particular, patients without a history of skull base surgery and orbital extension could obtain satisfactory esthetical and functional outcomes. However, the procedure had limited effectiveness for patients with a history of skull base surgery or orbital extension because esthetical and functional outcomes inevitably became worse.

Feasibility and Advantage of a Muscle-Sparing Laterally Based Pericranial Flap.

BACKGROUND: For a safe and reliable middle skull base reconstruction, the temporalis muscle flaps or pericranial-temporalis muscle flaps have usually been used as the first-choice in clinical practice. But these flaps have an inevitable disadvantage, namely, temporal hollowing. To address this problem, in this study, the authors describe the feasibility and advantages of using a muscle-sparing laterally based pericranial flap. METHOD: The authors reviewed 19 patients who had undergone middle skull base reconstruction using laterally based pericranial flaps. There were two types of these flaps. One was the conventional type: a laterally based pericranial flap combined with the temporoparietal fascia and temporal muscle, that is a conventional laterally based pericranial flap (C-PCF). The other was the muscle-sparing type: a laterally based pericranial flap combined with the temporoparietal fascia, but sparing and preserving the temporal muscle (MS-PCF). The first 9 patients were reconstructed with a C-PCF and the latter 10 patients were reconstructed with an MS-PCF. RESULTS: There was no significant difference between C-PCF and MS-PCF as regards reconstructive time and postoperative hospital stay. In addition, there was no significant difference between C-PCF and MS-PCF in regard to perioperative complications. The rate of temporal hollowing did not reach a significant difference; MS-PCF patients tended to have less temporal hollowing (10%) compared with C-PCF patients (55.6%). DISCUSSION: An MS-PCF could provide safe and reliable skull base reconstruction without lengthening reconstructive time or increasing complications. Moreover, an MS-PCF improves the esthetical results of surgery on skull base patients and provides an extra option for other reconstructive procedures by preserving the temporal muscle.

Persistence of psychological distress and correlated factors among patients with head and neck cancer.

OBJECTIVE: Many patients with head and neck cancer (HNC) suffer from psychological distress associated with dysfunction and/or disfigurement. Our aim was to evaluate the ratio of patients with persistence of psychological distress during hospitalization and identify the predictors of persistence or change in psychological distress among HNC patients. METHOD: We conducted a single-center longitudinal study with self-completed questionnaires. We evaluated psychological distress (the Hospital Anxiety and Depression Scale; HADS) and functional level (the Functional Assessment of Cancer Therapy-Head and Neck Scale; FACT-H&N) among patients during hospitalization at the Medical Hospital of Tokyo Medical and Dental University. RESULTS: Of 160 patients, 117 (73.1%) completed the questionnaire at both admission and discharge. Some 42 (52.5%) patients reported persistent psychological distress. The physical well-being of patients with continued distress was significantly lower than that of other patients (21.7 ± 4.7, 19.4 ± 6.1, 19.5 ± 5.4; p < 0.01), and the emotional well-being of patients with continued distress was significantly lower than that in patients with no distress and reduced distress (22.3 ± 3.5, 20.5 ± 2.5; p < 0.01). Significant of results: Impaired physical and emotional function appears to be associated with persistent psychological distress among HNC patients. Psychological interventions focused on relaxation, cognition, or behavior may be efficacious in preventing such persistent distress.

Use of Intraoperative Fluorescent Indocyanine Green Angiography for Real-Time Vascular Evaluation of Pericranial Flaps.

BACKGROUND: Pericranial flaps (PCFs) have been widely used for skull base reconstruction. The key to successful skull base reconstruction using PCF depends on flap vascularity, but there have been no reports describing the real-time vascularity of PCF. In this study, we performed intraoperative fluorescent indocyanine green angiography to evaluate the real-time vascularity and viability of PCF and to estimate the reliability of this flap. METHODS: Eleven anteriorly based PCF (with a bilateral pedicle, ipsilateral pedicle, and random-pattern flap) and 11 laterally based PCF (with and without temporal muscle) were included in this study. The flap vascularity of each flap type considering the patients' background was evaluated using indocyanine green angiography intraoperatively. RESULTS: Anteriorly based PCF had significantly better vascularity compared to laterally based PCF. In anteriorly based PCF, there was no significant difference in vascularity between PCF with bilateral pedicles and an ipsilateral pedicle. In laterally based PCF, PCF without temporal muscle showed a wider vascular area compared to PCF with temporal muscle. As for the patient background, those older than 45 years, body mass index more than 25, and who were smokers tended to have lower vascularity. Preoperative radiation therapy did not show any significant differences in terms of flap vascularity. CONCLUSIONS: Anteriorly based PCF had significantly better vascularity compared to laterally based PCF and seemed safer to harvest regardless of flap pedicle type. Also, the feasibility of harvesting muscle sparing laterally based PCF was indicated. Finally, being older than 45 years, a body mass index more than 25, or being a smoker might increase the risk of reducing flap vascularity.

[Combined Anterior Craniofacial Resection for Locally Advanced Ethmoid Carcinomas].

OBJECTIVE: Carcinoma of the ethmoid sinus is very rare, and treatment for locally advanced tumors remains as a formidable challenge to the clinician. We reviewed cases of ethmoid carcinoma in which anterior craniofacial resection had been undertaken and evaluated the safety and validity of the operative methods. METHODS: We retrospectively reviewed 13 patients with ethmoid carcinoma who underwent combined anterior craniofacial resection. We evaluated the surgical procedures, complications, outcomes, local recurrence, and the survival rate. RESULTS: Coronal incision and anterior craniotomy were performed in all cases. Four out of 13 cases underwent ipsilateral orbital exenteration due to involvement of the orbital contents. There were no potentially fatal complications, except for two cases of epidural abscesses which were successfully cured. Positive surgical margins were observed in 6 patients, and they received postoperative radiotherapy and/or chemotherapy. Local recurrences occurred in 4 cases, and 3 died at 9, 11, and 49 months after the surgery. Distant metastasis was not observed during the observation period. The overall 5-year survival rate was 75.2% (Kaplan-Meier method). CONCLUSION: These tumors were safely removed without severe complications and postoperative mortality. Combined anterior craniofacial resection is an effective and safe option for treatment of locally advanced ethmoid carcinomas after various preoperative treatments.

Risk factors for cervical lymph node metastasis in superficial head and neck squamous cell carcinoma.

INTRODUCTION: The necessity of transoral surgery for head and neck carcinoma is increasing, but its indications for the treatment of superficial head and neck carcinomas have not yet been established. This study was intended to help establish the standard indications for transoral surgery and additional therapy in patients with superficial head and neck carcinoma. METHODS: Sixty-two patients with 83 superficial head and neck carcinoma underwent transoral tumor resection at the Cancer Institute Hospital between June 2006 and September 2011. We measured the tumor size and thickness, examined the gross appearance, permeation of vessels, and droplet infiltration, and analyzed the correlations between each parameter. RESULTS: Sessile type of tumor on gross appearance showed a significantly higher incidence of thickness≥1000 µm than the other types. Tumor thickness≥1000 µm was associated with higher incidences of permeation of vessels, droplet infiltration, and cervical lymph node metastasis. CONCLUSIONS: In superficial head and neck carcinoma, if the endoscopic gross appearance is the sessile type, tumor thickness is likely to be ≥1000 µm and risk of cervical lymph node metastasis is increased.

Extended orbital exenteration for sinonasal malignancy with orbital apex extension: surgical technique and clinical analysis.

OBJECT: The majority of sinonasal malignancies present with advanced disease, and cure rates are generally poor. Surgical extirpation remains the mainstay of treatment. In cases of sinonasal malignancy with orbital apex extension, gross-total tumor resection requires orbital exenteration and bony skull base resection around the orbital apex to provide sufficient margins. In this retrospective study, the authors describe their surgical strategy in and technique for orbital exenteration with orbital apex resection in patients at Tokyo Medical and Dental University who had sinonasal malignancy with orbital apex extension. They also analyzed the clinical features of and the results in these patients. METHODS: Between February 2001 and August 2012 at the authors' institution, sinonasal malignancy with orbital apex extension was treated using craniofacial tumor resection with orbital exenteration including skull base bone around the orbital apex. The authors describe this technique and analyze the surgical indications, extent of resection, primary tumor location, outcome, pathological findings, and neoadjuvant and adjuvant therapies of the patients who underwent the technique. RESULTS: The patients consisted of 12 men and 3 women with a mean age of 47.7 years (range 14-79 years). The longest postoperative follow-up was 9.5 years, and the shortest was 0.67 year (mean 3.0 years). Tumor originated at the ethmoid sinus in 6 patients (40%), maxillary sinus in 5 (33%), nasal cavity in 2 (13%), and orbital cavity and maxillary bone in 1 patient each (7%). Histological analysis of tumor specimens revealed squamous cell carcinoma in 9 patients (60%), rhabdomyosarcoma in 2 (13%), and small cell carcinoma, mucoepidermoid carcinoma, adenoid cystic carcinoma, and Ewing sarcoma in 1 patient each (7%). Two patients experienced recurrences at 1 and 5 months after treatment; these patients died at 5 and 10 months after surgery, respectively. Estimated 5-year recurrence-free survival (RFS) was 86.7%, and estimated 5-year overall survival (OS) was 86.2%; there was no perioperative mortality. None of the patients had new neurological deficits as a result of the surgery, but 5 patients suffered infectious complications from the graft transplanted into the cavity after resection. There were no other perioperative complications. CONCLUSIONS: These authors are the first to describe a technique for extended orbital exenteration with orbital apex skull base resection. The technique provided sufficient margins for gross-total resection of the sinonasal malignancy with orbital apex extension. The estimated 5-year OS and RFS rates were high, and the perioperative complication rate was acceptably low, demonstrating the safety and efficacy of this technique.

Reliability and validity of the Head and Neck Cancer Inventory (HNCI) in Japanese patients.

OBJECTIVE: This project evaluated the psychometric properties of a translated version of the Head and Neck Cancer Inventory (HNCI) for use with Japanese patients. The HNCI is a measure for assessing the quality of life (QoL) of head and neck cancer patients and survivors. The present study was aimed at investigating the reliability and validity of this translated instrument. METHOD: Some 165 patients with head and neck cancer (HNC) were enrolled at the Tokyo Medical and Dental University Hospital. The instrument's internal consistency and test-retest reliability were evaluated. Criterion-related validity was assessed by correlations between the HNCI and the Functional Assessment of Cancer Therapy-Head and Neck (FACT-H&N) scales. RESULTS: Some 29 of the 30 items in the original version were selected to comprise the Japanese version of the HNCI (Japanese HNCI). Investigation of criterion-related validity using the FACT-H&N demonstrated significant correlations (Spearman's ρ = 0.47-0.63). The value of Cronbach's α for each subscale ranged from 0.84 to 0.87. Test-retest reliability showed an intraclass correlation coefficient (ICC) of 0.62-0.79. SIGNIFICANCE OF RESULTS: The reliability and validity of the Japanese HNCI were evaluated. Although its classification is different from the original U.S. version, the Japanese HNCI is a self-administered questionnaire that can assess quality of life (QoL) in patients with head and neck cancer.
