Impact of age at diagnosis of head and neck cancer on incidence of metachronous cancer.

BACKGROUND: Metachronous cancer in patients with head and neck cancer (HNC) is common and is associated with a poor prognosis. We aimed to evaluate the incidence of metachronous cancer at different sites according to age at diagnosis of index HNC. METHODS: We collected data on 2011 patients with oral cancer, oropharynx cancer, hypopharyngeal cancer, and laryngeal cancer as index cancers using the Osaka International Cancer Institute Cancer Registry database between 2005 and 2016. Among these, we analyzed 1953 patients after excluding 5 patients who were not followed-up and 53 patients with simultaneous multiple index cancers. We evaluated the cumulative incidence of metachronous cancer in the esophagus, lung, and other sites according to age at diagnosis of the index HNC using the Kaplan-Meier method. Multivariate logistic regression analysis was performed to identify factors that influenced the incidence of metachronous cancers following HNC. RESULTS: The cumulative incidence of metachronous esophageal cancer in young patients (< 65 years) was significantly higher than that in old patients (≥ 65 years) (12.1% vs 8.5% at 5 years, and 16.5% vs 11.2% at 10 years; p = 0.015). On the other hand, the cumulative incidence of the other cancers in young patients was significantly lower than that in old patients (7.8% vs 12.2% at 5 years, and 13.9% vs 15.3% at 10 years; p = 0.017). The cumulative incidence of lung cancer was not significance according to age at diagnosis of the index HNC. In the multivariate analysis, histological type (squamous cell carcinoma) and lesion location (hypopharynx and larynx) were independently associated with metachronous cancers. Moreover, age at diagnosis of the index HNC (< 65 years), histological type (squamous cell carcinoma) and lesion location (hypopharynx) were significant predictors of metachronous esophageal cancer incidence and lesion location (hypopharynx) was a significant predictor of metachronous lung cancer incidence. CONCLUSION: Risk stratification of metachronous cancers with age and other predictors may help to properly manage patients with HNC. TRIAL REGISTRATION: The present study is a non-intervention trial.

Economic Analysis of a Three-Arm RCT Exploring the Delivery of Intensive, Prophylactic Swallowing Therapy to Patients with Head and Neck Cancer During (Chemo)Radiotherapy.

Research advocates for the use of intensive, prophylactic swallowing therapy to help reduce the severity of dysphagia in patients receiving (chemo)radiotherapy ([C]RT) for head/neck cancer (HNC). Unfortunately, the intensity of this therapy, coupled with growing patient numbers and limited clinical resources, provides challenges to many international cancer facilities. Telepractice has been proposed as a potential method to provide patients with greater support in home-practice, whilst minimising burden to the health service. This study investigated the clinical and patient-attributable costs of delivering an intensive, prophylactic swallowing therapy protocol via a new telepractice application "SwallowIT" as compared to clinician-directed FTF therapy and independent patient self-directed therapy. Patients (n = 79) with oropharyngeal HNC receiving definitive (C)RT were randomised to receive therapy via a: clinician-directed (n = 26), patient-directed (n = 27), or SwallowIT-assisted (n = 26) model of care. Data pertaining to health service costs (service time, consumables, therapy resources), patient-attributable costs (travel and wages) and patient-reported health-related quality of life (QoL) (AQoL-6D) were collected. SwallowIT provided a cost-efficient model of care when compared to the clinician-directed model, with significant cost savings to both the health service and to HNC consumers (total saving of $1901.10 AUD per patient; p < 0.001). The SwallowIT model also proved more cost-effective than the patient-directed model, yielding clinically significantly superior QoL at the end of (C)RT, for comparable costs. Overall, when compared to the alternate methods of service-delivery, SwallowIT provided a financially viable and cost-effective method for the delivery of intensive, prophylactic swallowing therapy to patients with HNC during (C)RT.

Tumor volume as a prognostic marker in p16-positive and p16-negative oropharyngeal cancer patients treated with definitive intensity-modulated radiotherapy.

PURPOSE: To investigate the impact of primary gross tumor volume (pGTV) and nodal gross tumor volume (nGTV) in oropharyngeal squamous cell carcinoma (OPSCC) and the difference in their role between human papillomavirus (HPV)-positive and HPV-negative patients. METHODS: The patient cohort consists of 91 OPSCC patients treated with definitive radiochemotherapy or radiotherapy using intensity-modulated radiotherapy (IMRT). All patients had a minimum follow-up of 31 months. Volume measurements were made from computer tomography (CT) scans and HPV status was assessed by p16 immunohistochemistry. The end points were as follows: overall survival (OS), disease-free survival (DFS) and locoregional control (LRC). RESULTS: pGTV was a significant independent prognostic factor for overall survival (OS; p = 0.020) in p16-negative patients. nGTV of p16-negative tumors had significant prognostic value in all end points in multivariate analyses. High-stage (III-IVc) p16-negative tumors were only associated with significantly poorer OS (p = 0.046) but not with poorer LRC or DFS when compared with the low-stage (I-II) tumors. nGTV of p16-positive tumors was an independent prognostic factor for DFS (p = 0.005) and LRC (p = 0.007) in multivariate analyses. CONCLUSION: pGTV may serve as an independent prognostic factor in p16-negative patients and nGTV may serve as an independent prognostic factor both in p16-positive and p16-negative patients treated with radiochemotherapy or radiotherapy using IMRT. Tumor volume may have an impact on selecting patients for de-escalation protocols in the future, both in p16-positive and p16-negative patients.

Optimizing Outcomes following Total and Subtotal Tongue Reconstruction: A Systematic Review of the Contemporary Literature.

Background More than 45,000 Americans are diagnosed with oropharyngeal cancer annually and multimodal treatment often requires wide excision, lymphadenectomy, chemotherapy, and radiation. Total and subtotal lingual resection severely impairs speech, swallow, and quality of life (QoL). This study investigates functional outcomes and QoL following subtotal and total tongue resection with free tissue transfer reconstruction. Materials and Methods A systematic review of the English language literature was performed using PubMed, Ovid, Embase, and Cochrane databases based on predetermined inclusion/exclusion criteria. Included studies were reviewed for surgical technique, adjuvant treatment, surgical and functional outcomes, and QoL. Results From an initial search yield of 1,467 articles, 22 studies were included for final analysis. Speech intelligibility was correlated with the volume and degree of protuberance of the neotongue. Adjuvant therapy (radiation) and large tumor size were associated with worse speech and swallow recovery. At 1 year follow-up, despite 14 to 20% rates of silent aspiration, 82 to 97% of patients resumed oral feeding. Neurotized flaps have been demonstrated to improve flap sensation but have not yet demonstrated any significant impact on speech or swallow recovery. Finally, many patients continue to experience pain after surgery, but patient motivation, family support with physician, and speech therapist follow-up are associated with improved QoL scores. Conclusion Tongue reconstruction is dictated by the amount of soft tissue resection. Taking into consideration the most common factors involved after tongue resection and reconstruction, further studies should focus on more objective measurements to offer solutions and maximize final outcomes.

[A clinical observation of an extensive chondroma of oro- and laryngopharynx]. / Klinicheskoe nabliudenie obshirnoi khondromy roto- i gortanoglotki.

This article was designed to report a rare case of oropharyngeal chondroma in a 31 year-old male patient. Computed tomography revealed an encapsulated cystic-solid tissue mass having the clear-cut contours with multiple diffuse foci of calcification in the tissue thickness. The neoplasm was morphologically characterized as a chondroma. The tumour was removed with the use of the modified Lauers-Balon procedure with the dissection of the lower jaw.

Functional swallowing outcomes following treatment for oropharyngeal carcinoma: a systematic review of the evidence comparing trans-oral surgery versus non-surgical management.

BACKGROUND: Trans-oral surgical and non-surgical management options for oropharyngeal squamous cell carcinoma (OPSCC) appear to offer similar survival outcomes. Functional outcomes, in particular swallowing, have become of increasing interest in the debate regarding treatment options. Contemporary reviews on function following treatment frequently include surrogate markers and limit the value of comparative analysis. OBJECTIVES OF REVIEW: A systematic review was performed to establish whether direct comparisons of swallowing outcomes could be made between trans-oral surgical approaches (trans-oral laser microsurgery (TLM)/trans-oral robotic surgery (TORS)) and (chemo)radiotherapy ((C)RT). TYPE OF REVIEW: Systematic review. SEARCH STRATEGY: MEDLINE, Embase and Cochrane databases were interrogated using the following MeSH terms: antineoplastic protocols, chemotherapy, radiotherapy, deglutition disorders, swallowing, lasers, and trans-oral surgery. EVALUATION METHOD: Two authors performed independent systematic reviews and consensus was sought if opinions differed. The WHO ICF classification was applied to generate analysis based around body functions and structure, activity limitations and participation restriction. RESULTS: Thirty-seven citations were included in the analysis. Twenty-six papers reported the outcomes for OPSCC treatment following primary (C)RT in 1377 patients, and 15 papers following contemporary trans-oral approaches in 768 patients. Meta-analysis was not feasible due to varying methodology and heterogeneity of outcome measures. Instrumental swallowing assessments were presented in 13/26 (C)RT versus 2/15 TLM/TORS papers. However, reporting methods of these studies were not standardised. This variety of outcome measures and the wide-ranging intentions of authors applying the measures in individual studies limit any practical direct comparisons of the effects of treatment on swallowing outcomes between interventions. CONCLUSIONS: From the current evidence, no direct comparisons could be made of swallowing outcomes between the surgical and non-surgical modalities. Swallowing is a multidimensional construct, and the range of assessments utilised by authors reflects the variety of available reporting methods. The MD Anderson Dysphagia Inventory is a subjective measure that allows limited comparison between the currently available heterogeneous data, and is explored in detail. The findings highlight that further research may identify the most appropriate tools for measuring swallowing in patients with OPSCC. Consensus should allow their standardised integration into future studies and randomised control trials.

A Comparison of Clinical Outcomes Between HPV Positive and HPV Negative Squamous Cell Carcinomas of the Oropharynx.

Human papilloma virus (HPV) infection is now recognized as a major risk factor for the development of oropharyngeal head and neck cancers, specifically HPV type 16. HPV-16 positive oropharyngeal cancer may in fact represent a distinct disease entity which is associated with improved prognosis and survival (National Cancer Institute, 2016). In this study, we examined the characteristics of patients with early stage HPV-16 positive oropharyngeal squamous cell carcinoma and their post-operative course contrasting the findings to patients with HPV-16 negative tumors. Overall, it was noted that 30-day readmissions and surgical site infections are not affected by the HPV status of the tumor. Robotic surgery is used more frequently with patients who were positive for the HPV infection, and the data suggest that there is a trend toward shorter length of hospital stays as well as a difference in postoperative complications.

Validity of patient-reported swallowing and speech outcomes in relation to objectively measured oral function among patients treated for oral or oropharyngeal cancer.

The objective of this study was to test the construct validity of the patient-reported outcomes Swallowing Quality of Life Questionnaire (SWAL-QOL) and Speech Handicap Index (SHI) in relation to objectively measured oral function among patients treated for oral or oropharyngeal cancer. The study sample consisted of patients treated for oral or oropharyngeal cancer. Outcome measures were the SWAL-QOL and the SHI, and the Functional Rehabilitation Outcomes Grade (FROG), a test to measure oral and shoulder function. Spearman's rank correlation coefficient was used to test associations between the SHI and SWAL-QOL scales, and the FROG scales. During a study period of 3 months, 38 patients (21 males, 17 females; mean age 54 years) were included who visited the outpatient clinic for follow-up care 6-155 months after surgical treatment (n = 14) or combined surgery and radiotherapy (n = 24) for oral (n = 21) or oropharyngeal cancer (n = 17). Most SWAL-QOL and SHI scales (except the SWAL-QOL Fatigue scale) correlated significantly with one or more FROG oral function scales. None of the SWAL-QOL and SHI scales correlated significantly with the FROG shoulder function scale. These results support the construct validity of the SWAL-QOL and SHI questionnaires for assessing speech and swallowing problems in daily life that are moderately but significantly related to oral function. A multidimensional assessment protocol is recommended for use in clinical practice and for research purposes for measuring oral function and swallowing- and speech-related problems in daily life among head and neck cancer patients.

Functional outcomes after TORS for oropharyngeal cancer: a systematic review.

Summarize functional outcomes after transoral robotic surgery (TORS) ± adjuvant therapy for oropharyngeal cancer (OPC). A systematic review was conducted. The MEDLINE database was searched (MeSH terms: TORS, pharyngeal neoplasms, oropharyngeal neoplasms). Peer-reviewed human subject papers published through December 2013 were included. Exclusion criteria were as follows: (1) case report design (n < 10), (2) review article, or (3) technical, animal, or cadaver studies. Functional outcomes extracted included feeding tube dependence, swallow examination findings, speech ratings, velopharyngeal insufficiency, pneumonia, and oral intake measures. Twelve papers comprising 441 patients with OPC treated with TORS ± adjuvant therapy were included. Feeding tube rates were the most commonly reported functional outcome. Excluding prophylactic placement, 18-39% of patients required gastrostomy placement, typically during adjuvant therapy. Chronic gastrostomy dependence ranged from 0 to 7% (mean follow-up 11-26 months), regardless of disease stage. Composite MD Anderson Dysphagia Inventory (MDADI) scores ranged from 65.2 to 78 (89 patients, 3 series, mean follow-up 12-13 months). Videofluoroscopic swallowing studies were not systematically reported. Incidence of postoperative pneumonia was 0-7%. Predictors of swallowing function included baseline function, T-stage, N-stage, tongue base primary tumors, and adjuvant chemoradiation. Rates of transient hypernasality were 4-9%. A single study suggested dose-dependent effects of adjuvant therapy (none, radiation alone, chemoradiation) on diet scores at 6 and 12 months. Crude end points of functional recovery after TORS ± adjuvant therapy suggest promising swallowing outcomes, depending on the functional measure reported.

Functional outcomes after transoral robotic surgery for squamous cell carcinoma of the oropharynx.

Over the past decade, the development of transoral robotic surgery (TORS) brought a new opportunity in the treatment of early T-stage oropharyngeal squamous cell carcinoma (OPSCC). The objective of this study is to review the functional outcomes after TORS. Indeed, dysphagia is among the most commonly cited functional impairments in OPSCC survivors treated by surgeries with an open approach or conventional radiotherapy. We performed a review of the literature and analysed functional outcomes after TORS. Althought the technique is very recent, early functional and oncologic outcome data are promising and the major studies analysing these parameters support that TORS is feasible and safe as well as oncologically and functionally efficacious.

[New Combination Therapy to Improve the Functional Preservation Rate of the Larynx in Laryngeal, Oropharyngeal, and Hypopharyngeal Cancers].

A new combination therapy has been developed to achieve high overall survival and functional laryngeal preservation rates in head and neck cancers, which require laryngectomy. In order to treat the primary site without resection, superselective intra-arterial infusions with DCF anterogradely and 60 mg/m2 of DOC and 60 mg/m2 of CDDP via the femoral artery on day 1 were administered, followed by continuous intravenous instillation of 750 mg/m2/day of 5-FU for 5 days from day 2. The 5- year survival rate was 70.4% in laryngeal cancer, 72.8% in oropharyngeal cancer, and 68.5% in hypopharyngeal cancer. The 5-year functional laryngeal preservation rate was 71.0% in laryngeal cancer, 63.4% in oropharyngeal cancer, and 65.2% in hypopharyngeal cancer. In addition to regional lymph node control, a thorough neck dissection was performed. Good overall survival and functional laryngeal preservation rates were achieved.

What is the best treatment for patients with human papillomavirus-positive and -negative oropharyngeal cancer?

The discovery that the human papilloma virus (HPV) is associated with a high and increasing percentage of oropharyngeal squamous cell carcinomas (SCCs) is among the most significant advances in the field of head and neck oncology. HPV-positive oropharyngeal cancer (HPVOPC) has clinical, etiologic, pathologic, and molecular features that distinguish it from HPV-negative disease. Increasingly, HPVOPC is being diagnosed in clinical practice because of the easy availability of p16 immunohistochemistry, a surrogate marker of HPV. The superior prognosis of HPVOPC has led to a reexamination of treatment approaches, and clinical trials are currently investigating strategies to deintensify treatment to reduce acute and late toxicity while preserving efficacy. This is of particular interest in low-risk patients. Unfortunately, patients with HPV-negative tumors still have high rates of locoregional failure and more efficacious treatments are required. This review of oropharyngeal SCC focuses on current and investigational treatment strategies in patients with both HPV-positive and HPV-negative oropharyngeal SCC.

Associations between voice quality and swallowing function in patients treated for oral or oropharyngeal cancer.

PURPOSE: The purpose of this study was to investigate associations between voice quality and swallowing function in patients treated for oral or oropharyngeal cancer. METHODS: Recordings of speech and videofluoroscopy of 51 patients after treatment for oral or oropharyngeal cancer were analysed. Acoustic voice parameters (fundamental frequency (F0), perturbation (jitter %, shimmer %), harmonics-to-noise ratio (HNR), and intensity (extracted from the vowels /a/, /i/, and /u/)) were compared to swallowing function parameters as assessed via videofluoroscopy (oral, oropharyngeal, and total transit time; estimated percent of oral, oropharyngeal, and total residue; oropharyngeal swallowing efficiency (OPSE), and the penetration/aspiration (PA-) scale). RESULTS: Stepwise multivariate regression analyses revealed that jitter, shimmer, and HNR were not associated with swallowing function. Higher voice intensity in all three vowels /a/, /i/, and /u/ was significantly associated with a higher score on the PA-scale (more penetration and aspiration). Higher voice intensity and F0 were significantly associated with lower OPSE. CONCLUSION: Higher voice intensity was significantly associated with higher amount of penetration/aspiration, and higher voice intensity and fundamental frequency were significantly associated with swallowing inefficiency. Possible explanations may be found in overcompensation by increased laryngeal muscular strength resulting in increased intensity and pitch during phonation. However, the physiology of associated voice and swallowing function is yet unclear, and more research is recommended.

Applications of medial sural perforator free flap for head and neck reconstructions.

Oropharyngeal defects left after tumor resection are usually reconstructed with radial forearm or anterolateral thigh (ALT) perforator free flaps, but these flaps can be too thin or too thick. In this study, medial sural perforator free flaps with intermediate volumes were used for oropharyngeal reconstruction. Of the 243 patients with oropharyngeal cancer who underwent head and neck reconstruction between October 2006 and October 2011, the medial sural perforator free flap was used 20 times. The number and locations of the main sizable perforators, the dimensions and thickness of the flap, and the length of the pedicle were recorded. Satisfactory results were achieved in 18 patients. The flaps in the two remaining cases failed. The vertical locations of the main sizable medial sural perforators were 6 to 15 cm away from the popliteal crease. The medial sural perforator free flaps ranged from 4 to 10 mm in thickness. Medial sural perforator free flaps may be an alternative for medium-sized defects that cannot be properly reconstructed with radial forearm or ALT perforator free flaps because of their inappropriate flap volume.

[Evaluation of quality of life and swallowing in patients with cancer of the oropharynx treated with assisted transoral robotic surgery]. / Evaluation de la qualité de vie et de la déglutition des patients atteints d'un cancer de l'oropharynx traités par chirurgie transorale assistée par robot.

OBJECTIVES: To present the preliminary results of the qualiit of life and quality of swallowing in a series of 15 patien! treated with oropharyngectomy by transoral robotic-assisted (CTAR) (robot da Vinci, Intuitive Surgical ). MATERIALS AND METHODS: A prospective monocentric non-randomized study of 15 patients with cancer of the oropharynx. Were analyzed: demographics, quality of life questionnaires (QLQ-C30 and H&N 35 EORTC) and quality of swallowing questionnairex (MDADI, DHI and EAT 10) with an average of 1 year after the end of the treatment. RESULTS: Fifteen patients (10 males and 5 females), mean age of 65 years (47-73 years) were included. The tumours were classified as: cT1: 4; cT2: 10 cT3: 1. Five of the 15 patients received postoperative chemoradiotherapy as histo-pathological studies showed multiple metastatic cervical lymph nodes +/- capsular rupture. For the analysis of the quality of life and quality of swallowing, the patients were divided into two groups. Group A included patients who underwent CTARs and group B, patients operated by CTAR with adjuvant chemoradiotherapy. At 12 months of the procedure, all patients had a deglutition considered as normal without feeding tube nor tracheostomy. With the three scales used, the quality of swallowing was satisfactory for all patients. It was better for patients in group A than for patients in group B. In terms of quality of life, the EORTC QLQ-C30 scale showed our patients had a high rate of satisfaction scale in "health and overall quality of life". For the EORTC H&N35 questionnaire, mean scores for "specific symptoms" were also low except for the following three items "dry mouths", "sticky saliva" and "sexuality problem". The first two items were statistically more frequent (p = 0.02 and p = 0.001) in group B patients. CONCLUSION: After transoral robotic-assisted oropharyngectomy, patients have a good quality of life and swallowing. Postoperative chemoradio-therapy compromises the quality of swallowing. Multicentric studies are required to confirm these preliminary results.

Evaluation of swallowing by Sydney Swallow Questionnaire (SSQ) in oral and oropharyngeal cancer patients treated with primary surgery.

This work aimed at evaluating patients' swallowing functions by a newly validated swallow-specific questionnaire, the Sydney Swallow Questionnaire (SSQ), in a cohort of oral and oropharyngeal cancer patients. Mean/median SSQ scores were calculated and compared with study variables using the Mann-Whitney U test and Kruskal-Wallis test. The mean composite SSQ scores (SD) for the base of tongue, oral tongue, and tonsillar cancer patients were 663.8 (382.8), 456.2 (407.6), and 283.0 (243.1), respectively (p = 0.005); for advanced vs. early T stage disease they were 918.1 (319.5) vs. 344.8 (292.1) (p ≤ 0.001); for patients <60 years vs. ≥60 years they were 549.3 (415.1) vs. 314.0 (247.3) (p = 0.02); and for patients with reconstruction vs. without reconstruction they were 676.5 (410.5) vs. 331.9 (286.5) (p = 0.002). SSQ is a useful tool for evaluation of swallowing in head and neck cancer patients. Site of cancer, T stage, patient's age, and reconstruction directly affect post-treatment swallow outcome.

Cine MRI of swallowing in patients with advanced oral or oropharyngeal carcinoma: a feasibility study.

Treatment of oral and oropharyngeal cancer may cause dysphagia. Purpose is to examine whether cine magnetic resonance imaging (MRI) yields additional information compared to standard examination in the evaluation of posttreatment dysphagia and mobility of oral and oropharyngeal structures. Thirty-four cine MRIs were made in 23 patients with advanced oral and oropharyngeal cancer, consisting of an MR image every 800 ms during swallowing which is compared to videofluoroscopy and quality of life questionnaires. A scoring system was applied to assess mobility on cine MR and videofluoroscopy leading to a score ranging from 9 to 17. Cine MRI of the swallowing in a midsagittal plane visualized the tumor (if located in the same plane), important anatomic structures and surgical reconstructions. Posttreatment mobility on cine MRI and videofluoroscopy was significantly diminished compared to pretreatment, mean pretreatment cine MRI score was 10.8 and posttreatment 12.4 (p = 0.017). Impaired mobility on cine MRI was significantly correlated to more swallowing problems (Spearman's correlation coefficient 0.73, p = 0.04), on videofluoroscopy not. Cine MRI is a promising new technique as an adjunct to standard examinations for evaluation of swallowing in patients with oral and oropharyngeal cancer. Cine MRI directly visualizes the dynamics of swallowing and allows evaluation of pre- and posttreatment differences. Abnormal findings are significantly correlated with subjective swallowing complaints of patients.

An exploratory study of the influence of clinico-demographic variables on swallowing and swallowing-related quality of life in a cohort of oral and oropharyngeal cancer patients treated with primary surgery.

There are insufficient data on swallowing and the consequences of its dysfunction in patients with cancers of the oral cavity (OC) and oropharynx (OP) that are treated with primary surgery. The study attempts to explore the effect of important clinico-demographic variables on post-treatment swallowing and related quality of life (QOL) in post-surgical OC and OP cancer patients. Sixty-two consecutive OC and OP cancer patients completed the MD Anderson Dysphagia Inventory (MDADI) questionnaire. Mean scores were computed. Comparison of scores based on mean ranks were performed using Mann-Whitney U test or Kruskal-Wallis test. Level of significance was set at P ≤ 0.02. Adjustments were made for multiple comparisons. Significantly worse mean (SD) QOL scores were observed in late T-stage (T3/T4) versus early T-stage (T1/T2) patients for global domain, physical domain, functional domain and emotional domains [44.4 (21.9) vs. 78.7 (22.7) (P < 0.001); 50.0 (9.4) vs. 75.9 (16.3), (P < 0.0001); 57.8 (20.6) vs. 84.1 (16.7), (P < 0.001) and 55.2 (18.0) vs. 78.5 (16.3), (P < 0.001)], respectively. Patients undergoing reconstruction versus without reconstruction had worse QOL scores; 58.8 (26.9) versus 79.5 (22.8), (P < 0.01); 61.2 (15.1) versus 76.4 (17.5), (P = 0.002); 65.4 (20.5) versus 86.3 (15.9), (P < 0.0001) and 63.3 (18.8) versus 79.8 (16.3), (P < 0.01), respectively, for global, physical, functional and emotional domains. Advanced T-stage, reconstruction, younger age and base of tongue tumours have a negative impact on post-treatment swallow function and related QOL in these patients.

Probable Change of Sleep Parameters after Resection and Reconstruction Surgeries in Patients with Oral Cavity or Oropharyngeal Cancers.

In patients of oral cavity or oropharyngeal cancers, resection of the tumor and reconstruction of the defect may reduce the framework, add a bulky flap, alter the tissue flexibility, and contribute to postoperative obstructive sleep apnea (OSA). Postoperative OSA and the potential consequences may decrease the survival rate and reduce patients' quality of life. It is unclear whether the surgery is associated with postoperative OSA. Here, we compared the polysomnographies (PSGs) before and after the surgery in 15 patients of oral cavity or oropharyngeal cancers (out of 68 patients of head and neck cancers) without a chemo- or radio-therapy. Each patient received the second PSG before the start of any indicated adjuvant therapy to prevent its interference. There were 14 men and 1 woman, with a mean age and a standard deviation (SD, same in the following) of 56.2 ± 12.8 years. There were 6 tongue cancers, 5 buccal cancers, 2 tonsil cancer, 1 lower gum cancer, and 1 trigone cancer. The results show that the surgery changed sleep parameters insignificantly in apnea-hypopnea index (AHI), mean oxyhemoglobin saturation of pulse oximetry (SpO2), minimum SpO2, mean desaturation, and desaturation index but increased mean heart rate in the patients with free flaps. These results hint that the effect of surgery on developing OSA was small in this sample, with a longer plate or a larger framework for a bulkier free flap. It needs future studies with a large sample size to generalize this first observation.

Communicative Participation and Quality of Life in Pretreatment Oral and Oropharyngeal Head and Neck Cancer.

OBJECTIVE: To determine how communicative participation is affected in patients with oral and oropharyngeal head and neck cancers (HNCs) pretreatment and whether communication function predicts HNC-specific quality of life (QOL) before treatment, beyond known demographic, medical, psychosocial, and swallowing predictors. STUDY DESIGN: Cross-sectional study. SETTING: Tertiary care academic medical center. METHODS: Eighty-seven patients with primary oral (40.2%) or oropharyngeal (59.8%) HNC were recruited prior to treatment. T stage, tumor site, and p16 status were extracted from medical records. Demographic and patient-reported measures were obtained. Communicative participation was measured using the Communicative Participation Item Bank (CPIB) General short form. A hierarchical regression analysis included demographic, medical, psychosocial, and functional measures of swallowing and communication as predictors; the University of Washington Quality of Life (UW-QOL v4) composite score was the predicted variable. RESULTS: Median (SD) baseline CPIB scores were 71.0 (11.83); patients with oral cancers reported worse scores. A final sequential hierarchical regression model that included all variables explained 71% of variance in QOL scores. Tumor site, T stage, and p16 status accounted for 28% of variance (P < .001). Perceived depression predicted an additional 28% of the variance (P < .001). Swallowing and communicative participation together predicted an additional 12% of variance (P = .005). Tumor site, perceived depression, swallowing, and communication measures were unique predictors in the final model. Finally, communicative participation uniquely predicted QOL, above and beyond other predictors. CONCLUSION: Pretreatment communication predicted QOL and was negatively affected in some oral and oropharyngeal patients with HNC.
