RESUMEN

PURPOSES: Being diagnosed with oral cancer is a life-threatening life event. It often induces social, emotional and psychological consequences and may cause depressive disorders. The primary aim of this study was to identify and quantify the personal and clinical characteristics involved in depression for patients who have been treated for oral cavity malignancies, with a 5-year follow-up period after treatment. The secondary aim of this study was to identify the clinical factors that increase a patient's risk of experiencing depression 5 years after treatment. METHODS: Patients with primary oral cancer were assessed for up to 5 years after primary treatment. A mixed-model analysis was performed, with depression measured by the Center for Epidemiologic Studies Depression Scale as outcome measure. RESULTS: A total of 141 patients were included in the study. Factors associated with depression were gender, tumour location and having an emotion-oriented coping style. The occurrence of depression within 5 years after treatment could be reliably predicted by a patient's gender, the location of their tumour and the extent to which they had an emotion-oriented coping style. CONCLUSIONS: This study revealed that being female, having a maxillary tumour and having an emotion-oriented coping style are associated with higher levels of depressive symptoms in patients treated for oral cancer up to 5 years post-treatment. A substantial proportion of the patients with oral cancer experienced high levels of depression both before and after their treatment, suggesting that adequate diagnostics and care are needed to try to prevent severe depression in these patients.

RESUMEN

Evaluation of relevant clinical outcomes in patients with bilateral cleft lip and palate (BCLP) after secondary aveolar bone grafting (SABG) and premaxilla osteotomy (PMO), through the use of a new scoring system. Data were collected retrospectively from all patients with BCLP who were operated on between 2004 and 2014, at the end of follow-up. The treatment protocol consisted of SABG + PMO in patients aged between 9 and 13 years. At the end of follow-up, the following parameters were scored: (un)interrupted dental arch, skeletal sagittal relationship, bone height using the Bergland/Abyholm criteria, and the presence of postoperative fistula. These parameters were combined to produce a dento-maxillary scoring system, giving a final score between 1 and 10. For statistical analysis, the independent t-test was used. Of 55 children, 45 were suitable for analysis. The mean age at time of surgery was 12.0 years (8.9-16.4 yrs), and the mean follow-up time was 11.7 years (5.8-15.8 yrs). The average number of surgeries executed under general anesthesia was 6 (range: 3-11). The average dento-maxillary score in this patient cohort was 7.6 (1-10; median: 8). Among these patients, 31 had an uninterrupted dental arch; the average Bergland/Abyholm score was 2.07; 30 patients exhibited an Angle class I incisor relationship; and, in 38 cases, the oronasal communication was closed after SABG + PMO treatment. A significant effect of fistulas was seen on dento-maxillary score (p = 0.001). Specifically, a significant effect of fistulas was seen on interrupted dental arch (p = 0.002) and on Bergland/Abyholm score (p = 0.037). The proposed dento-maxillary scoring system is a straightforward tool that can be used to describe and analyze the amount of dento-maxillary rehabilitation at the end of the treatment. Persistence of oronasal fistulas in patients with BCLP has a significant impact on interruption of the dental arch, and can influence dental results at the end of the second decade.

RESUMEN

OBJECTIVE: To evaluate factors affecting incidence of complications after secondary alveolar bone grafting with premaxillary osteotomy (SABG + PO) in children with complete bilateral cleft of lip and palate (BCLP). MATERIALS AND METHODS: Data were collected from children with BCLP treated with SABG + PO from 2004 to 2014 at our institute. Preoperative parameters included age, donor site, race, gingival health, bone quality around cleft-related teeth, premaxilla position, graft timing, presence of canines in the cleft, and presence of deciduous teeth around the cleft area. Logistic regression and the chi-squared test were used to assess correlations and the incidence of complications. RESULTS: In the 64 patients, a significant correlation was found between complication rate and timing of bone grafting with respect to early versus late SABG + PO (p = 0.041), age > 12 years (p = 0.011; odds ratio (OR) 5.9; 95% confidence interval (CI) 1.49-23.93), malposition of the premaxilla (p = 0.042; OR 3.3; 95% CI 1.04-10.13), and preoperative bone quality around cleft-related teeth (p = 0.005; OR 5.3; 95% CI 1.6-17.2). CONCLUSIONS: The timing of SABG + PO is essential, as early SABG + PO is associated with fewer complications. A malpositioned premaxilla and poor bone quality around cleft-related teeth are associated with more complications. Therefore, preoperative orthodontic repositioning of the malpositioned premaxilla before SABG + PO should be considered. CLINICAL RELEVANCE: Analysis of treatment protocols and complications for BCLP patients underscores that proper timing of SABG + PO and correct premaxilla repositioning help reduce complications.

RESUMEN

BACKGROUND: The aim of this study was to identify factors influencing shoulder and/or neck function in patients up to five years after treatment. MATERIALS AND METHODS: Lateral flexion of the neck, ipsilateral forward flexion, and abduction of the shoulder were measured. Potential factors were entered into a linear mixed model analysis to create a multivariate model for describing the results. RESULTS: Predicted neck and shoulder function was negatively influenced by higher age before intervention. Contralateral flexion of the neck was lower for patients undergoing surgery and radiotherapy compared to surgery. Ipsilateral flexion of the neck is influenced by a higher age at baseline. Ipsilateral shoulder abduction is lower for female gender, bone graft/flap reconstruction, and more extensive neck dissection. Ipsilateral forward flexion of the shoulder is lower for bone graft/flap reconstruction and better for patients with a T2 tumor in comparison to T3 and T4 tumors, as predicted. CONCLUSION: By our five-year follow-up outcomes of this study, neck and/or shoulder impairments can be found for high-risk patients by physiotherapists.

RESUMEN

OBJECTIVE: To evaluate midfacial growth and dental arch relationships in patients treated for bilateral cleft lip and palate (BCLP). MATERIALS AND METHODS: Data were collected from all patients with BCLP treated at our hospital between 2004 and 2014, with or without premaxillary osteotomy (PO). Dental casts for pre-secondary alveolar bone grafting with PO (SABG + PO) and end-point dental casts were analyzed using the BAURU yardstick scoring system. Pre-SABG + PO, post-SABG + PO, and end-point SABG + PO lateral cephalograms were analyzed. The correlation between both scoring systems was calculated. RESULTS: There were no significant differences between the BAURU scores for centers in a previous study and those collected here. A negative correlation was found between the pre-SABG + PO ANB (Angle between A-point, Nasion and B-point) angle and pre-SABG + PO BAURU scores (R = -0.58; p = 0.000), the long-term post-SABG + PO ANB and mean end-point BAURU (R = -0.50; p = 0.000), and the pre-SABG + PO ANB and mean end-point BAURU (R = -0.51; p = 0.000). CONCLUSION: We found no significant difference between pre-SABG + PO and end-point BAURU scores. There was a decrease in the SNA (Angle between Sella, Nasion and A-point) and ANB angle over time, indicating delayed growth of the maxilla. We found a negative correlation between the pre-SABG ANB and end-point BAURU scores. Pre-SABG ANB can be used to predict the need for Le Fort I osteotomy at age 18.

RESUMEN

BACKGROUND AND OBJECTIVES: Evaluation of mandibular reconstructions with free fibula flaps. Identification of factors associated with major recipient site complications, that is, necessitating surgical intervention under general anaesthesia. METHODS: Seventy-nine reconstructions were included. The following factors were analyzed: fixation type, number of osteotomies, site of defect (bilateral/unilateral), surgeon, sex, ASA classification, continuous smoking, pathological N-stage, age, defect size, flap ischemic time, and postoperative radiotherapy. Proportional hazards regression was used to test the effect on the time between reconstruction and intervention. RESULTS: Sixty-nine (87%) of the 79 fibula flaps were successful at the last follow-up. Forty-eight major recipient site complications occurred in 41 reconstructions. Nineteen complications required surgical intervention within six weeks and were mostly vascular problems, necessitating immediate intervention. These early complications were associated with defects crossing the midline, with an estimated relative risk of 5.3 (CI 1.1-20, P = 0.01). Twenty-nine complications required surgical intervention more than 6 weeks after the reconstruction. These late complications generally occurred after months or years, and were associated with smoking, with an estimated relative risk of 2.8 (CI 1.0-8.3, P = 0.05). CONCLUSIONS: Fibula flaps crossing the midline have a higher risk of early major recipient site complications than unilateral reconstructions. Smoking increases the risk of late complications.

RESUMEN

OBJECTIVES: To investigate the feasibility of an intervention using the National Comprehensive Cancer Network Distress Thermometer and Problem List with nurse-guided follow-up and the effect on depressive symptoms, health-related quality of life, and worry of cancer in patients with head and neck cancer.
. SAMPLE & SETTING: 110 patients with head and neck cancer in a two-arm randomized, controlled trial in an outpatient clinic of a university hospital. 
. METHODS & VARIABLES: Patients were randomized to usual care (n = 57) or the intervention group (n = 53), which consisted of screening with the Distress Thermometer and Problem List plus nurse-guided follow-up lasting about 20 minutes three to four times during 12 months. Intention-to-treat analysis was performed using linear mixed models with outcomes at 6 and 12 months and baseline adjustment.
. RESULTS: The intervention showed moderate compliance and acceptable session duration. Intervention participants were satisfied with nurses' care. Depressive symptoms, health-related quality of life, and worry of cancer were not significantly different in the two treatment groups. The intervention seemed feasible in clinical practice, but no effects on patient outcomes were seen.
. IMPLICATIONS FOR NURSING: Patients with head and neck cancer appreciated the opportunity to discuss their problems and challenges with a nurse. Nurses supported patients with basic psychosocial care, minor interventions, and referral possibilities.

RESUMEN

BACKGROUND: No consensus exists on the optimal treatment protocol for orofacial clefts or the optimal timing of cleft palate closure. This study investigated factors influencing speech outcomes after two-stage palate repair in adults with a non-syndromal complete unilateral cleft lip and palate (UCLP). METHODS: This was a retrospective analysis of adult patients with a UCLP who underwent two-stage palate closure and were treated at our tertiary cleft centre. Patients ≥17 years of age were invited for a final speech assessment. Their medical history was obtained from their medical files, and speech outcomes were assessed by a speech pathologist during the follow-up consultation. RESULTS: Forty-eight patients were included in the analysis, with a mean age of 21 years (standard deviation, 3.4 years). Their mean age at the time of hard and soft palate closure was 3 years and 8.0 months, respectively. In 40% of the patients, a pharyngoplasty was performed. On a 5-point intelligibility scale, 84.4% received a score of 1 or 2; meaning that their speech was intelligible. We observed a significant correlation between intelligibility scores and the incidence of articulation errors (P<0.001). In total, 36% showed mild to moderate hypernasality during the speech assessment, and 11%-17% of the patients exhibited increased nasalance scores, assessed through nasometry. CONCLUSIONS: The present study describes long-term speech outcomes after two-stage palatoplasty with hard palate closure at a mean age of 3 years old. We observed moderate long-term intelligibility scores, a relatively high incidence of persistent hypernasality, and a high pharyngoplasty incidence.

RESUMEN

OBJECTIVES: The aim of this study was to compare costs and clinical outcomes of two protocols for implant placement in edentulous oral cancer patients: implant placement during ablative surgery and postponed implant placement. MATERIAL AND METHODS: All edentulous patients who underwent curative tumor surgery between 2007 and 2009 at the Radboud university medical center (Radboudumc) and UMC Utrecht, both in the Netherlands, were included retrospectively. At the Radboudumc, 79 of 98 patients received implants during ablative surgery. At the UMC Utrecht, 18 of 95 patients received implants after a disease-free period of at least 6 months, because satisfying conventional dentures could not be made. Costs, implant details and clinical outcomes were recorded retrospectively up to 5 years after tumor surgery. RESULTS: Individual costs of implant placement were lower in the during-ablative-surgery protocol (€2235 vs. €4152), while implant failure and loading were comparable to the postponed-placement protocol. In the during-ablative-surgery protocol, more patients received implant-retained overdentures (62% vs. 17%) and more patients had functioning dentures (65% vs. 47%), which were placed at an earlier stage (291 vs. 389 days after surgery). Overall costs of the during-ablative-surgery protocol were higher, as more patients received implants and functioning implant-retained dentures, which were more expensive than conventional dentures. CONCLUSIONS: Placing implants during ablative surgery lowered the individual costs of implant placement and led to more patients with functioning dentures, while implant failure and loading were comparable to postponed placement.

RESUMEN

INTRODUCTION: Fibroblast growth factor receptor family member proteins (FGFR1-4) have been identified as promising novel therapeutic targets and prognostic markers in a wide spectrum of solid tumors. The present study investigates the expression and prognostic value of four FGFR family member proteins in a large multicenter oral cavity squamous cell carcinoma (OCSCC) and oropharyngeal squamous cell carcinoma (OPSCC) cohort. METHODS: Protein expression of FGFR1-4 was determined by immunohistochemistry on tissue microarrays containing 951 formalin-fixed paraffin embedded OCSCC and OPSCC tissues from the University Medical Center Utrecht and University Medical Center Groningen. Protein expression was correlated to overall survival using Cox regression models, and bootstrapping was performed as internal validation. RESULTS: FGFR proteins were highly expressed in 39-64 % of OCSCC and 63-79 % of OPSCC. Seventy-three percent (299/412) of OCSCC and 85 % (305/357) of OPSCC highly co-expressed two or more FGFR family member proteins. FGFR1 protein was more frequently highly expressed in human papillomavirus (HPV)-negative OPSCC than HPV-positive OPSCC (82 vs. 65 %; p = 0.008). Furthermore, protein expression of FGFR family members was not related to overall survival in OCSCC or OPSCC (p > 0.05). CONCLUSION: FGFR family members are frequently highly expressed in OCSCC and OPSCC. These FGFR family member proteins are therefore potential targets for novel therapies that are urgently required to improve survival of OCSCC and OPSCC patients.

RESUMEN

BACKGROUND: The timing of placement as well as the functional benefit of interforaminal implants in edentulous patients treated for oral cancer is unclear. METHODS: Fifty-six patients were recruited at 2 institutions. In 1 institution, interforaminal implants were placed during ablative surgery, the other institution used conventional prosthodontics with optional placement of implants postsurgery (postponed-placement). Masticatory performance, bite force, and subjective masticatory function were assessed before and 6 months, 1 year, and 5 years after surgery. RESULTS: Implant-retained overdentures (IODs) demonstrated the highest bite force and the least problems with solid food and food choice. Masticatory performance was equal for IODs and conventional dentures. After 5 years, IODs from patients in the during-ablative-surgery cohort tend to have higher bite force and masticatory performance than those from patients in the postponed-placement cohort. CONCLUSION: IODs produce the highest overall masticatory function. Implant placement during ablative surgery seems to be functionally beneficial. © 2016 Wiley Periodicals, Inc.

RESUMEN

BACKGROUND: Since head and neck cancer is characterized by poor survival rates, there is a demand for novel therapeutic targets and prognostic biomarkers. An upcoming therapeutic target is the fibroblast growth factor receptor (FGFR) family. However, their prognostic role in head and neck cancer remains unclear. OBJECTIVE: To systematically review current evidence on the prognostic value of FGFR family members in head and neck squamous cell carcinoma (HNSCC). METHODS: A systematic search of PubMed, Embase, and the Cochrane Library was performed for publications up to 14 May 2014. Two reviewers screened all articles and included prognostic studies on the molecular biomarkers FGFR1-5 in any type of HNSCC. Relevant studies were assessed on risk of bias using the Quality in Prognostic Studies (QUIPS) tool. Data on FGFR aberrations and survival outcome were extracted from relevant studies. The prognostic value of FGFR aberrations was compared among studies. RESULTS: The initial search yielded 1568 publications of which 12 fulfilled the inclusion criteria. Four studies reported FGFR1 gene amplification (9.3-17.4 %) and FGFR1 protein overexpression (11.8 %) in HNSCC. FGFR1 protein expression by cancer-associated fibroblasts correlated with poor survival outcome in one study (p < 0.01). Eight studies reported high rates of FGFR4 Gly388Arg polymorphisms (32.5-54.2 %) and FGFR4 protein overexpression (16-35 %), with varying correlations with survival. So far, no studies assessed the prognostic role of FGFR2, FGFR3, or FGFR5 in HNSCC. LIMITATIONS: Significant risk of bias has been identified among included studies. Therefore, cautious interpretation of the results is recommended. CONCLUSION: In conclusion, evidence was found for prognostic value of FGFR1 expression in cancer-associated fibroblasts in HNSCC. Prognostic evidence on the other FGFR family members in HNSCC is limited and conflicting. This emphasizes the need for future well-conducted prognostic studies.

RESUMEN

Fibroblast growth factor receptor 3 (FGFR3) is a member of the fibroblast growth factor receptor tyrosine kinase family. It has been identified as a promising therapeutic target in multiple types of cancer. We have investigated FGFR3 protein expression and FGFR3 gene copy-numbers in a single well-documented cohort of oral and oropharyngeal squamous cell carcinoma. Tissue microarray sets containing 452 formalin-fixed paraffin-embedded tissues were immunohistochemically stained with an anti-FGFR3 antibody and hybridized with a FGFR3 fluorescence in situ hybridization probe. FGFR3 protein expression was correlated with clinicopathological and survival data, which were retrieved from electronic medical records. FGFR3 mRNA data of 522 head and neck squamous cell carcinoma (HNSCC) were retrieved from The Cancer Genome Atlas (TCGA). Fibroblast growth factor receptor 3 (FGFR3) protein was overexpressed in 48% (89/185) of oral and 59% (124/211) of oropharyngeal squamous cell carcinoma. Overexpression of FGFR3 protein was not related to overall survival or disease-free survival in oral (HR[hazard ratio]: 0.94; 95% CI: 0.64-1.39; P = 0.77, HR: 0.94; 95% CI: 0.65-1.36; P = 0.75) and oropharyngeal squamous cell carcinoma (HR: 1.21; 95% CI: 0.81-1.80; P = 0.36, HR: 0.42; 95% CI: 0.79-1.77; P = 0.42). FGFR3 mRNA was upregulated in 3% (18/522) of HNSCC from the TCGA. The FGFR3 gene was gained in 0.6% (1/179) of oral squamous cell carcinoma but no amplification was found in oral and oropharyngeal squamous cell carcinoma. In conclusion, FGFR3 protein is frequently overexpressed in oral and oropharyngeal squamous cell carcinoma. Therefore, it may serve as a potential therapeutic target for FGFR3-directed therapies in oral and oropharyngeal squamous cell carcinoma.

RESUMEN

OBJECTIVE: The aim of this study was to investigate whether fibroblast growth factor receptor 4 (FGFR4) could serve as a potential therapeutic target, prognostic biomarker or biomarker predicting radiotherapy sensitivity in oral squamous cell carcinoma (OSCC) and oropharyngeal squamous cell carcinoma (OPSCC). METHODS: FGFR4 immunohistochemistry and FGFR4/CEN5q FISH were performed on tissue microarrays from 212 OSCC and 238 OPSCC patients. FGFR4 genotypes were determined by PCR and DNA sequencing in 76 random OPSCC samples. The response to radiotherapy was evaluated 3 months after the last radiotherapy treatment session by a head and neck radiation oncologist and/or surgeon during clinic visits. The results were correlated to overall survival and response to radiotherapy. RESULTS: The FGFR4 protein was overexpressed in 64% (153/238) of OPSCCs and 41% (87/212) of OSCCs. The FGFR4 gene was amplified in 0.47% (1/212) of OSCCs and 0.42% (1/238) of OPSCCs, and the FGFR4 Gly388Arg polymorphism was detected in 62% (47/76) of OPSCCs. FGFR4 protein expression, FGFR4 gene copy numbers and FGFR4 genotypes were not related to overall survival or response to radiotherapy in OSCC or OPSCC. CONCLUSION: FGFR4 is frequently overexpressed in OSCC and OPSCC in the absence of gene amplification, and may serve as a potential predictive marker for FGFR4-directed targeted therapy in OSCC and OPSCC.

RESUMEN

BACKGROUND: In Juvenile Idiopathic Arthritis (JIA) the temporomandibular joint (TMJ) can be involved leading to pain, dysfunction and growth disturbances of the mandible and associated structures. There may be value to a three minute screening protocol allowing the rheumatologist to detect TMJ involvement systematically. Reliability and validity of the TMJ protocol for detecting TMJ co-morbidity were determined in 74 consecutive JIA patients. METHODS: The assessments of the rheumatologist and of a reference examiner (RE) were compared and validity of the TMJ protocol was established using the disease activity (JADAS-27) as an external reference. RESULTS: The internal consistency of the protocol was 0.73 (Cronbach's alpha). The inter-examiner agreement between the rheumatologist and the RE varied between 0.25 and 0.87 (Cohen's Kappa). Sensitivity and specificity, with the JADAS "3.8" indicating minimal disease activity, were 0.57 and 0.77 respectively. The area under the curve (AUC) was 0.70. A cut-off value of two positive items was found to be an optimal threshold to select the patients with likely TMJ involvement. CONCLUSIONS: The use of the protocol is feasible in everyday clinical practice. Reliability and validity aspects were satisfactory. The screening protocol for TMJ involvement provides the rheumatologist with systematic and focused TMJ information which relates to the JIA disease activity (JADAS-27).

RESUMEN

OBJECTIVES: Segmental resection of the mandible causes functional, aesthetic and social problems affecting health-related quality of life (HRQoL). It is often assumed that reconstruction with composite free flaps guarantees better function and aesthetics than bridging the defect with reconstruction plates. METHODS: Using the European Organization for Research and Treatment of Cancer questionnaires (EORTC QLQ-C30 version 3.0 and EORTC QLQ-H&N35), we compared HRQoL in patients who received free fibula flaps versus reconstruction plates after segmental resection of the lateral mandible. RESULTS: Thirty-seven completed questionnaires (18 fibula reconstructions and 19 patients with reconstruction plates) were available. Reconstruction with a free fibula flap did not provide clear additional benefit to bridging the defect with a reconstruction plate after segmental resection of the lateral mandible. In particular aspects known to have the most impact on HRQoL like swallowing, speech and chewing were not influenced by the type of reconstruction. CONCLUSIONS: Reconstruction of segmental defects of the lateral mandible with free fibula flap and reconstruction plate resulted in comparable HRQoL. If dental rehabilitation by means of dental implants is not anticipated in the fibula, then plate reconstruction with adequate soft tissue remains a suitable technique for the reconstruction of segmental defects of the lateral mandible.

RESUMEN

Despite improvements in both diagnostic and therapeutic strategies, the prognosis of oral squamous cell carcinoma (OSCC) has not changed significantly over the last decades. Prognosis of OSCC particularly depends on the presence of nodal metastasis in the neck. Therefore, proper determination of the nodal status is pivotal for appropriate treatment. Unfortunately, current available imaging techniques (magnetic resonance imaging or ultrasound even with fine needle aspiration of suspected lymph nodes (LNs)) fail to detect occult nodal disease accurately. Clinicians in head and neck oncology urgently need new diagnostic tools to reliably determine the presence of nodal metastasis of the neck. Gain of the chromosomal region 11q13 is one of the most prominent genetic alterations in head and neck cancer and is associated with poor prognosis and metastasis. The aim of this systematic review and meta-analysis was to determine the diagnostic value of either 11q13 amplification or amplification/protein overexpression of individual genes located on 11q13 to detect nodal metastasis in OSCC. A search was conducted in Pubmed, EMBASE, and Cochrane, and 947 unique citations were retrieved. Two researchers independently screened all articles and only 18 were found to meet our inclusion criteria and were considered of sufficient quality for meta-analysis. Pooled results of those show that both amplification of CCND1 and protein overexpression of cyclin D1 significantly correlate with lymph node metastasis (LNM) in OSCC. In addition, amplification of CCND1 shows a negative predictive value of 80 % in the detection of LNM in early stage OSCCs which are clinically lymph node negative although this evidence is sparse and should be validated in a larger homogeneous cohort of T1-2 OSCC.

RESUMEN

PURPOSE: Little is known about the variables that moderate the response to psychosocial interventions to decrease depressive symptoms in cancer patients. The purpose of this study was to determine whether variables associated with depressive symptoms in cancer patients in general moderate the response to a nurse-led psychosocial intervention in patients with head and neck cancer. METHODS: This study is a secondary analysis of a randomized controlled trial evaluating the effect of the nurse counseling and after intervention (NUCAI) on depressive symptoms 12 months after cancer treatment in patients with head and neck cancer. Of 205 patients, 103 received the NUCAI and 102 care as usual. Twenty-one variables were selected for analysis and a linear regression analyses including interaction terms was performed for each variable separately. Significant moderators were post hoc probed. RESULTS: Four moderators were found: marital status, global quality of life, emotional functioning, and social functioning. Patients who were married/living together or had low scores for global quality of life, and emotional or social functioning at baseline benefited more from the NUCAI than patients who were single or with high scores for global quality of life and emotional or social functioning. CONCLUSIONS: Marital status, global quality of life, and emotional and social functioning of head and neck cancer patients should be evaluated to determine whether they might benefit from a psychosocial intervention to combat depressive symptoms. Further research is necessary to replicate results and to contribute to the knowledge needed to make screening and personalized patient care possible.

RESUMEN

OBJECTIVES: Can a synthetic bone substitute be used to repair the alveolar cleft to bypass donor site morbidity as well as to shorten the operating time? In earlier experimental studies, micro-structured beta-tricalcium phosphate (ß-TCP) provided similar bone healing when compared with grafting with iliac crest bone. This justifies the clinical evaluation of this bone substitute in the human alveolar cleft situation. DESIGN: Prospective clinical study. SETTING: University clinic. PARTICIPANTS: Seven patients, all with unilateral alveolar cleft, were randomly included for alveolar cleft repair with ß-TCP in 2010 and 2011. MAIN OUTCOME MEASURES: In all patients, the alveolar cleft was repaired by micro-structured ß-TCP grafting. Our assessments were distilled from cone beam computed tomography scans taken preoperatively, 1 week postoperatively, and 6 months postoperatively. A volumetric outcome could be realized. RESULTS: Six months after the operative grafting of micro-structured ß-TCP into the alveolar cleft, the bone volume thus acquired was satisfactory. We found an average bone volume percentage of 73% ± 6% compared with the original cleft volume. CONCLUSIONS: Previous experimental and clinical studies and the initial findings of this pilot study now elucidate a path toward the clinical use of micro-structured ß-TCP bone substitute for repair of the alveolar cleft.

RESUMEN

BACKGROUND: Patients with oral cancer can develop restricted mouth opening (trismus) because of the oncologic treatment. METHODS: Maximum mouth opening (MMO) was measured in 143 patients shortly before treatment and 0, 6, and 12 months posttreatment, and the results were analyzed using a linear mixed-effects model. RESULTS: In every patient, MMO decreased after treatment. The patients who underwent surgery, recovered partially by 6 and 12 months after treatment, whereas the patients who received both surgery and radiotherapy or primary radiotherapy did not recover. Tumor location, tumor size, and alcohol consumption had independent effects on MMO. Having trismus (MMO <35 mm) 1 year after treatment was associated most strongly with pretreatment MMO, receiving both surgery and radiotherapy, and maxillary or mandibular tumor involvement. CONCLUSION: Postoperative radiotherapy and maxillary or mandibular tumor involvement are the highest contributing risk factors to decreasing MMO and the subsequent development of trismus after oral cancer treatment.
