Abstract
Prospective randomized studies have demonstrated a survival benefit of immunotherapy in stage IV cutaneous melanoma. Some retrospective studies have hypothesized a synergistic effect of radiation and immunotherapy. Our objective was to identify whether there is a survival benefit for patients treated with radiation and immunotherapy in stage IV cutaneous melanoma of the head and neck (CMHN). The National Cancer Database was used to identify patients with stage IV CMHN between 2012 and 2014. These patients were stratified based on receipt of radiation and immunotherapy. Adjusted Cox regression was used to analyze overall survival. A total of 542 patients were identified with stage IV CMHN, of whom 153 (28%) patients received immunotherapy. Receipt of immunotherapy (hazard ratio [HR] 0.69, P = 0.02) and negative LNs (HR 0.50, P = 0.002) were independently associated with improved survival, whereas radiation conferred no survival benefit (HR 1.17, P = 0.26). Patients who received immunotherapy without radiation were associated with significantly improved survival compared with those who received immunotherapy with radiation (P < 0.0001). However, of patients who received radiation, the addition of immunotherapy did not seem to improve survival (P = 0.979). In stage IV CMHN, immunotherapy confers a 32 per cent survival benefit. The use of immunotherapy in patients who require radiation, however, is not associated with improved survival.

Abstract
INTRODUCTION:
Contouring has become an increasingly important aspect of radiation therapy due to inverse planning, and yet is extremely time-consuming. To improve contouring efficiency and reduce potential inter-observer variation, the atlas-based auto-segmentation (ABAS) function in Velocity was introduced to ICON cancer centres (ICC) throughout Australia as a solution for automatic contouring.

METHODS:
This paper described the implementation process of the ABAS function and the construction of user-defined atlas sets and compared the contouring efficiency before and after the introduction of ABAS.

RESULTS:
The results indicate that the main limitation to the ABAS performance was Velocity's sub-optimal atlas selection method. Three user-defined atlas sets were constructed. Results suggested that the introduction of the ABAS saved at least 5 minutes of manual contouring time (P < 0.05), although further verification was required due to limitations in the data collection method. The pilot rollout adopting a 'champion' approach was successful and provided an opportunity to improve the user-defined atlases prior to the national implementation.

CONCLUSION:
The implementation of user-defined ABAS for head and neck (H&N) and female thorax patients at ICCs was successful, which achieved at least 5 minutes of efficiency gain.

Abstract
BACKGROUND:
The scapular system free flap has been increasing in popularity to reconstruct short segment mandibular bony defects. It is important to assess donor site morbidities systematically.

METHODS:
Prospective cohort study using objective measures of range of motion (ROM) and shoulder strength were measured. Subjective disability was evaluated with validated questionnaires-Neck Disability Impairment Index and Shoulder Pain and Disability Index.

RESULTS:
Twenty-six patients were recruited-19 with scapular tip and 7 with lateral border scapular free flap. Decreased ROM on the operated side was noted for shoulder abduction, shoulder flexion, and external rotation. No significant difference was noted for shoulder extension. Strength was reduced for shoulder flexion, shoulder abduction, and external rotation. Subjective measurements did not indicate significant shoulder function disruption.

CONCLUSION:
Patients with scapular free flap reconstruction did not experience significant shoulder morbidity. Measures of shoulder ROM and power were objectively affected; however, subjective measures of shoulder disability were not significantly affected.

Abstract
BACKGROUND:
The mechanistic target of rapamycin (MTOR) plays a key role in regulating cell growth and metabolism and is commonly overexpressed in head and neck cancer (HNSCC). This study investigated the association of MTOR with clinical outcome in human papilloma virus (HPV) positive and negative HNSCC patients treated by chemoradiation.

METHODS:
A tissue microarray (TMA) consisting of cores from 109 HNSCC patients treated by definitive chemoradiation was constructed and stained with antibodies against p16 and MTOR and expression correlated with clinicopathological features and clinical outcome.

RESULTS:
MTOR varied widely between tumor cores and was not associated with HPV status or clinicopathological features. There was a positive correlation with pre-treatment FDG uptake. (P = .01). In HPV negative patients, MTOR predicted for shorter locoregional control (P = .02), diseases free survival (P = .02), and overall survival (P = .04). MTOR expression was not associated with outcome in HPV positive patients.

CONCLUSIONS:
Prognostic significance of MTOR expression depends on HPV status.

Abstract
OBJECTIVES:
To report our institutional experience, management, and outcomes of cutaneous periauricular squamous cell carcinoma (SCC).

STUDY DESIGN:
Retrospective chart review.

SETTING:
Tertiary academic center.

SUBJECTS:
Patients undergoing treatment of cutaneous periauricular SCC from 2000 to 2016.

RESULTS:
A total of 112 patients had a median follow-up of 24.5 months, a mean ± SD age of 75.7 ± 10.6 years, and a strong male predominance (93.8%). Site distribution shows 87 (77.7%) auricular, 26 (23.2%) preauricular, and 10 (8.8%) postauricular lesions. Of auricular lesions, tumors involved the tragus (n = 3, 3.4%), helix/antihelix (n = 47, 54.0%), conchal bowl (n = 31, 35.6%), external auditory canal (n = 18, 16.1%), and lobule (n = 3, 3.4%). Most patients presented at stage I (52.7%) versus stages II (28.6%), III (6.3%), and IV (12.5%). Patients were largely treated surgically with primary tumor resection ranging from wide local excision to lateral temporal bone resection (± parotidectomy and neck dissection), with 17.0% and 5.4% receiving adjuvant radiation and chemoradiation, respectively. Metastatic spread was seen to the parotid (25.9%) and neck (26.8%), with most common cervical spread to level II. Overall survival, disease-specific survival, and disease-free survival at 3 years were 62%, 89%, and 56%, respectively. Nodal disease was associated with worse disease-specific survival (P < .001) and disease-free survival (P = .042). Pre- and postauricular sites were associated with worse overall survival (P = .007) relative to auricular sites.

CONCLUSION:
Among cutaneous SCC, periauricular subsites pose treatment challenges related to surrounding anatomy and represent a unique tumor population. The reported propensity toward recurrence and patterns of metastasis may better guide treatment of aggressive tumors to include regional nodal dissection.

Abstract
Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous neuroendocrine neoplasia. Surgical resection is the first-line therapeutic option, and radiation therapy is an alternative treatment for inoperable cases. Herein, we report a case of primary MCC (cT2N0M0, stage IIA) of the head and neck region. This case was misdiagnosed as a metastatic tumor and referred to the department of radiation oncology for palliative irradiation. Additional immunohistochemical analysis confirmed the diagnosis of MCC, and the tumor was treated with definitive radiation therapy (66 Gy in 33 fractions), leading to complete in-field control. This case indicates that even in patients with suspected metastatic tumors referred for palliative treatment, patient characteristics and pathology should be carefully examined to avoid missing potentially controllable primary tumors. In such cases, MCC, although rare, should be included in the differential diagnosis of head and neck lesions.

Abstract
In order to investigate the genetic causes of hearing loss in a Chinese proband (in Family A) with enlarged vestibular aqueduct (EVA) and to investigate the genotype of two Chinese probands with SLC26A4 singe-allelic mutation and normal hearing (in Families B and C, respectively), the three probands and their parents were clinically and genetically evaluated. Twenty exons and flanking splice sites of the SLC26A4 gene were screened for pathogenic mutations via amplification with PCR and bidirectional sequencing. As controls, a group of 400 healthy newborns from the same ethnic background underwent SLC26A4 gene screening using the same method. The three probands all harbored two mutations in the SLC26A4 gene in the form of compound heterozygosity. The genotypes of mutations in Families A, B, and C are c.1211C>A/c.919-2A>G, c.1729G>A/c.919-2A>G, and c.1286C>A/c.919-2A>G, respectively. The missense mutations c.1211C>A (p.T430Q) in exon 10 and c.1729G>A (p.V577I) in exon 16 are both reported for the first time and were absent in 400 healthy newborns. c.1211C>A has Glutamine (Gln) at amino acid 430 instead of Threonine (Thr), and c.1729G>A has Isoleucine (Ile) at amino acid 577 instead of Valine (Val). c.1286C>A, a mutation previously reported in DVD and HGMD, was associated with Mondini deformity, but a proband with the c.1286C>A mutation in this study was normal. This study has demonstrated that the novel missense mutation c.1211C>A in compound heterozygosity with c.919-2A>G in the SLC26A4 gene is likely to be the cause of deafness in Family A. A novel variant, c.1729G>A, was identified and is likely benign. The pathogenicity of the c.1286C>A mutation warrants more in-depth study. These findings will broaden the spectrum of known SLC26A4 mutations in the Chinese population, providing more information for genetic counseling and diagnosis of hearing loss with EVA.

Abstract
Composite scaffolds can improve regenerative capacities of scaffolds in various tissue-engineering approaches. In order to generate a 3D printable scaffold that is capable of cartilage regeneration, decellularized extracellular matrix (DECM) of porcine nasal cartilage was added to 3D printed polycaprolactone (PCL) scaffolds. Subsequently, scaffolds (PCL, PCL/DECM and DECM) were seeded with human primary nasoseptal chondrocytes and differentiated with cartilage inductive medium for up to 42 days in vitro. Afterwards samples were analyzed with scanning electron microscopy, histology, biochemical assays and gene expression analysis. In short, results showed cell attachment and proliferation on all scaffolds. There was a trend towards ossification on pure PCL scaffolds, whereas we found evidence for cartilage tissue formation on DECM scaffolds as well as on PCL/DECM scaffolds. Moreover, biochemical analysis indicated an enhanced differentiation on novel PCL/DECM scaffolds. In conclusion, the addition of DECM to 3D printable PCL scaffolds may yield a new composite material for regenerative approaches in cartilage for facial reconstructive surgery. Further research will be necessary to evaluate these findings in vivo.

Abstract
PURPOSE:
Aspirin-exacerbated respiratory disease (AERD) is a severe form of chronic rhinosinusitis with nasal polyps (CRSwNP) accompanied by asthma and an aspirin intolerance. The underlying pathomechanism of AERD still remains unclear, recent data suggest a complex inflammatory imbalance. In the present study, we investigated the cytokine patterns in AERD, CRSwNP and healthy control patients. Furthermore, we describe the change in cytokine level in the course of aspirin desensitization (AD) with continuous intake of aspirin.

METHODS:
The study included a total of 104 participants, 48 healthy controls, 45 patients with nasal polyps and 11 patients with AERD undergoing AD. Nasal secretions were analyzed for IL-1β, IL-4, IL-5, IL-10, IL-12, IL-13, IL-17, THF-α, IFN-γ, eotaxin and ECP using Bio-Plex Human Cytokine Assay and Uni-CAP FEIA. Baseline measurements of cytokine levels were performed in all 104 patients; in patients with AERD, follow-up was performed 1-6 and 6-24 months after the initiation of AD.

RESULTS:
Our preliminary results show a TH2 dominated, eosinophilic milieu in AERD patients, which decreased in the first weeks of AD. However, after 6 months of AD, proinflammatory cytokines show a tendency to increase again. Also, TH1 as well as Treg associated cytokine seem to increase over time.

CONCLUSIONS:
For the first time, the present work shows the cytokine pattern in nasal secretions of AERD patients before and during AD. Further investigation of the complex interaction of inflammatory cytokines during AD might reveal important insights into the disease entity of AERD and open up new horizons for a targeted therapy.

Abstract
BACKGROUND:
The aim of the present work was to evaluate the impact of xerostomia on the quality of life of patients who underwent radiotherapy in the head and neck region.

MATERIAL AND METHODS:
This was a cross-sectional, quantitative study. The sample comprised 40 patients whose xerostomia was classified through the xerostomia inventory and the quality of life evaluated through the oral health impact profile questionnaire (OHIP).

RESULTS:
The majority of participants were male (75%), mean age 58.7 years. According to the degree of severity of the xerostomia, the average score among the participants was 36 points, this being considered moderate xerostomia. A significant impact was observed, with the median score 11 points, with the highest scores in the domains related to functional limitation, physical pain and physical disability. The majority of the participants (97.5%) had reduced salivary flow after the end of radiotherapy. There was a significant positive correlation between the degree of xerostomia and reduced quality of life, Pearson correlation 0.5421, (p<0.05).

CONCLUSION:
Based upon the results it is concluded that xerostomia has a negative impact on the quality of life of patients who undergo radiotherapy in the head and neck region.

Abstract
BACKGROUND:
Oral and pharynx cancer represent a serious global problem, reaching an incidence of half a million cases annually. The role of tobacco and alcohol have been studied and proven to be one of its risk factors. We also know that mouthwashes contain a variable percentage of alcohol, so there is a reasonable concern about their role in carcinogenesis.

MATERIALS AND METHODS:
To answer the PICOS (Population; Intervention; Comparison; Outcomes; Study) question: "Do patients (Population) who use alcohol-based mouthwashes (Intervention) compared to those who do not use them (Comparison) have higher acetaldehyde levels in saliva or higher risk of oral cancer development? (Outcomes)" Meta-analyses, systematic reviews, randomized and non-randomized clinical trials, case-control studies, and prospective and retrospective cohort studies were included (Study). Two independent authors conducted literature screening through MEDLINE, Scopus and the Cochrane Library, and they also conducted article and data extraction to undertake quality analyses. The main outcome measures were salivary acetaldehyde levels or the risk of oral cancer development. The most relevant data was extracted and the risk of bias from the studies included was also evaluated.

RESULTS:
497 references were obtained in the initial search. After eliminating the duplicates and evaluating titles and abstracts, a total of 26 articles were chosen to analyze the full text. 18 of these articles were excluded and finally 8 studies were included in the qualitative analysis: two meta-analyses, a clinical trial, three case-control studies and two cohort studies.

CONCLUSIONS:
It cannot be guaranteed that the use of mouthwash represents an independent risk factor for the development of head and neck cancer. However, the risk does increase when it occurs in association with other carcinogenic risk factors.

Abstract
PURPOSE:
Intensity Modulated Radiotherapy (IMRT) has changed the practice of radiotherapy since its implementation in the 1990s. The purpose of this study is to review current practice of IMRT in Malaysia.

METHODS:
A survey on medical physics aspects of IMRT is conducted on radiotherapy departments across Malaysia to assess the usage, experience and QA in IMRT, which is done for the first time in this country. A set of questionnaires was designed and sent to the physicist in charge for their responses. The questionnaire consisted of four sections; (i) Experience and qualification of medical physicists, (ii) CT simulation techniques (iii) Treatment planning and treatment unit, (iv) IMRT process, delivery and QA procedure.

RESULTS:
A total of 26 responses were collected, representing 26 departments out of 33 radiotherapy departments in operation across Malaysia (79% response rate). Results showed that the medical physics aspects of IMRT practice in Malaysia are homogenous, with some variations in certain areas of practices. Thirteen centres (52%) performed measurement-based QA using 2D array detector and analysed using gamma index criteria of 3%, 3 mm with variation confidence range. In relation to the IMRT delivery, 44% of Malaysia's physicist takes more than 8 h to plan a head and neck case compared to the UK study possibly due to the lack of professional training.

CONCLUSIONS:
This survey provides a picture of medical physics aspects of IMRT in Malaysia where the results/data can be used by radiotherapy departments to benchmark their local policies and practice.

Abstract
Sounds delivered to the ear move the tympanic membrane (TM), which drives the middle-ear (ME) ossicles and transfers the acoustic energy to the cochlea. Perforations of the TM result in hearing loss because of less efficient sound conduction through the ME. The patterns of TM motions, and thus ME sound transmission, vary with frequency and depend on many factors, including the TM thickness. In this study, we measured TM thickness, auditory brainstem responses (ABR), and ME transmission immediately following a controlled pars tensa perforation and after 4 weeks of spontaneous recovery in a gerbil model. It is found that after recovery, the hearing thresholds showed a sloping pattern across frequencies: almost back to normal levels at frequencies between 2 and 8 kHz, sloping loss in the low (<2 kHz) and mid-frequency (8-30 kHz) range, and little restoration at frequencies above 30 kHz. This pattern was confirmed by the measured ME pressure gains. The thickness of the healed TM did not return to normal but was 2-3 times thicker over a significant portion of the membrane. The increased thickness was not limited to the perforated area but expanded into intact regions adjacent to the perforation, which led to an increased thickness in general. Combined, these results suggest that TM thickness is an important factor in determining its vibration patterns and efficiency to transfer sounds to the ossicles and thus influencing ME sound transmission, especially for high-frequency sounds. The results provided both structural and functional observations to explain the conductive hearing loss seen in patients with abnormal TMs, e.g., caused by otitis media, spontaneously healed post-perforation, or repaired via tympanoplasty in the clinic.

Abstract
PURPOSE:
To systematically review the literature for articles evaluating differences in polysomnography (PSG) data when patients are on primarily daytime hemodialysis (conventional hemodialysis or continuous ambulatory peritoneal dialysis) versus nocturnal hemodialysis (nocturnal hemodialysis or nocturnal peritoneal dialysis). Then to perform a meta-analysis on the available PSG data, specifically evaluating differences in apnea hypopnea index (AHI) and mean saturation of oxygen (SpO2) between these two groups.

METHODS:
Two authors systematically searched MEDLINE/Pubmed, Scopus, EMBASE, CINAHL, and Cochrane. Searches were performed through December 6, 2018.

RESULTS:
A total of four adult crossover studies (91 patients, age 50.4 ± 12.4, BMI 25.1 ± 5.3) reported PSG data. The daytime hemodialysis (DHD) and nocturnal hemodialysis (NHD) AHI decreased from 24.6 ± 18.2 to 12.6 ± 11.8 (events/hour) with a mean difference of -11.9 [95% CI -13.47, -10.37], Z score of 15.07 (P < 0.00001). The standardized mean difference was -1.35 [95% CI -2.70, 0.01]. Two studies reported mean SpO2 changes during PSG. The DHD and NHD SpO2 increased from 92.7 ± 2.4 to 94.7 ± 2.2 with a mean difference of 2.26 [95% CI -0.18, 4.71], Z score 1.82 (P = 0.07).

CONCLUSION:
In the current literature, nocturnal hemodialysis improves AHI more than daytime hemodialysis. A trend towards improvement in mean SpO2 with nocturnal dialysis was noted, but did not reach statistical significance. Consideration can be given for transitioning patients who have end stage renal disease and sleep apnea from daytime to nocturnal hemodialysis as an adjunct to other treatment modalities.

Abstract
PURPOSE:
We evaluated the prognostic value of various grades of radiologic extranodal extension (rENE) and their potential roles in N-classification refinement for nasopharyngeal carcinoma (NPC).

METHODS AND MATERIALS:
All NPC patients treated with IMRT in our institution between 2005 and 2011 were included. Pre-treatment MR of cN+ cases were reviewed and rENE was recorded asG0: lymph nodes (LNs) without rENE; G1: tumor infiltrating beyond individual nodal capsule(s) into the surrounding fat plane; G2: coalescent nodal mass with unequivocal evidence of rENE; G3: tumor infiltrating beyond nodal capsule into adjacent structures. Multivariable analysis (MVA) assessed prognostic value of rENE for distant metastasis (DM) and death adjusted for age, gender, LDH, T-classification, N-classification, and chemotherapy cycles.

RESULTS:
A total of 1390 of 1616 (86%) NPC were cN+, and rENE was detected in 826/1390 (59%) patients: 256 (18.4%) G1-rENE, 487 (35%) G2-rENE, and 83 (6%) G3-rENE. MVA confirmed that G2-/G3-rENE had increased risk of DM (HR: 2.05/3.18, both p < 0.001) and death (HR: 1.62/2.39, p = 0.002/p < 0.001), while G1-rENE was non-prognostic (DM: p = 0.172; death: p = 0.320). We propose a refined N: New-N1: N1/N2 without G2-/G3-rENE; New-N2: N1_G2-rENE; New-N3: N2_G2-rENE, N1/N2_G3-rENE, or N3. The New-N classification had a lower AIC and higher c-index for DM (AIC: 3809.6 vs 3830.9; c-index: 0.700 vs. 0.677) and death (AIC: 3693.8 vs. 3705.9; c-index: 0.735 vs. 0.725) versus TNM-8 N.

CONCLUSIONS:
G2- and G3-rENE are independently prognostic for DM and death in NPC. Compared to the TNM8 N-classification, a refined N-classification incorporating G2- and G3-rENE improves prognostication of DM and mortality risk.

Abstract
Human papilloma virus (HPV) has emerged as the key etiologic driver in the majority of cancers at head and neck mucosal sites. First described in the uterine cervix and subsequently in oropharyngeal squamous cell carcinomas, the morphologic and clinical spectrum of HPV-related neoplasia has continued to expand and now includes a newly described entity in the sinonasal tract. A recent study has also suggested a role of HPV in some ocular adnexal sebaceous carcinomas. Herein, we review and concisely summarize the spectrum of HPV-driven neoplasia in the head and neck, with a focus on variant morphologies and newly-described entities including key differential diagnoses and clinical implications.

Abstract
The treatment of chronic migraine headache is quite challenging and new alternatives are still being explored for its management. Onabotulinum toxin A (BoNT-A) applied into extracranial muscles has been shown to inhibit the release of acetylcholine and local nociceptive peptides at the sensory nerve endings. As the highest concentration of extracranial pain fibers are located at/nearby the sutures, extracranial applications of BoTN-A are suggested to be performed to sutures rather than into the head and neck muscles in the treatment of chronic migraine. Moreover, in an animal study, BoTN-A is found to be more effective for decreasing the chemosensitivity of meningeal nociceptors when the total dose is injected along the sutures in comparison to being divided into sutures and cranial muscles. Of note, since BoNT-A injections performed with the blind/nontargeted technique have lower effectivity and several complications (muscle weakness, ptosis, facial paresis, etc.), the use of ultrasound guidance for targeting the cranial sutures is definitely expected to provide technical ease, better pain relief and toxin tolerance in chronic migraine.

Abstract
OBJECTIVE:
Morbidity from head and neck cancers (HNCs) and their treatment is significant, given their proximity to anatomical sites impacting facial appearance and function. Assessing the needs of HNC patients throughout their cancer journey is critical to informing quality care and improving quality of life. We aimed to identify available unmet needs measures in the HNC setting and appraise their content and psychometric properties.

METHODS:
We conducted a systematic search of five electronic databases (July 2007-July 2019) to identify studies of unmet needs in patients with HNC. In addition, three web-based patient-reported outcome measures (PROMs) databases were searched for unmet needs measures. Citations were screened for eligibility and identified measures reviewed for content coverage and psychometric properties. From identified measures and literature, a conceptual framework with 12 clinically relevant aspects of unmet needs was developed and used to assess the conceptual coverage of available unmet needs measures.

RESULTS:
Literature search identified 273 records of which 28 studies assessing unmet needs in HNC cancer met eligibility criteria. Seven unmet needs measures were identified from retrieved studies and seven additional measures from PROM databases. Thus 14 measures in total were reviewed. Content mapping revealed that three measures demonstrated excellent content validity (> 80% conceptual coverage): Patient Concerns Inventory (PCI), Needs Assessment for Advanced Cancer Patients (NA-ACP), and James Supportive Care Screening (JSCS).

CONCLUSION:
We recommend PCI be used to measure unmet needs in the HNC setting considering the importance of content validity over quantitative psychometric properties.

Abstract
BACKGROUND This study aimed to investigate the effects of xanthoxyletin, a plant-derived coumarin, on human oral squamous cancer cells in vitro and in mouse xenografts in vivo. MATERIAL AND METHODS The study included SCC-1 human oral cancer cells and EBTr normal embryonic bovine tracheal epithelial cells, which were treated with 0 µM, 5 µM, 10 µM, and 20 µM of xanthoxyletin for 24 hours. The MTT assay assessed cell viability, and autophagy was detected by electron microscopy. Cell apoptosis was investigated using 4',6-diamidino-2-phenylindole (DAPI), annexin V, and propidium iodide (PI) fluorescence flow cytometry, which was also used to investigate the cell cycle. Protein expression was measured by Western blot. Mouse xenografts were used for the in vivo evaluation of the effects of xanthoxyletin. RESULTS Xanthoxyletin significantly inhibited the proliferation of oral cancer cells (IC₅₀, 10-30 µM) with lower cytotoxicity for normal cells. Xanthoxyletin treatment was associated with G2/M arrest of the cell cycle and with increased apoptosis and autophagy of SCC-1 cells. Apoptosis and autophagy induced by xanthoxyletin were also associated with changes in expression of the apoptosis-associated proteins, Bax and Bcl-2, and the autophagy-associated proteins, LC3I, LC3II, Beclin 1, p62, and VSp34. Xanthoxyletin inhibited the expression of components of the signaling cascade of the MEK/ERK pathway in the SCC-1 oral cancer cells. The in vivo effects of xanthoxyletin showed inhibition of growth of mouse xenografts. CONCLUSIONS Xanthoxyletin inhibited the proliferation of human oral squamous carcinoma cells and induced apoptosis, autophagy, and cell cycle arrest by modulation of the MEK/ERK signaling pathway.
