Several studies have found that the computation of this scalar inference may be associated with a processing cost (e.g., Bott & Noveck, 2004; De Neys & Schaeken, 2007), which seems to argue in favour of theories according to which pragmatic inferencing is cognitively demanding (e.g., Sperber & Wilson, 1986). This argument holds on the premise that findings for 'some' can be generalised across the entire family of scalar words, which has been called into question by recent work highlighting the diversity within the class of scalar words (e.g., van Tiel, v...

We analyzed a lexicon based on a corpus of Dutch reading materials for primary school children to gain insight into the frequency distribution of different word types, i.e. words with similar word characteristics, both per grade and across grades. The frequencies of monomorphemic, concrete words and of polysemous words remained relatively stable, whereas that of multimorphemic and monomorphemic abstract words increased across grades.

Publication date: Available online 15 December 2018Source: Speech CommunicationAuthor(s): Hynek HermanskyAbstractThis paper postulates that linguistic message in speech is coded redundantly in both the time and the frequency domains. Such redundant coding of the message in the signal evolved over millennia of human evolution so that relevant spectral and temporal properties of human hearing can be used to extract these messages in the presence of noise. This view of human speech suggests a particular architecture of an automatic recognition (ASR) system in which longer temporal segments of spectrally-smoothed temporal trajectories of spectral energies in individual frequency bands of speech are used to derive estimates of the posterior probabilities of speech sounds.

Cytomegalovirus (CMV) is one of the largest and most complex of all known viruses, with a genome encoding approximately 165 genes. CMV is widely prevalent globally, but is immunologically controlled in healthy individuals with an intact immune system. The immune effector mechanisms involved do not eliminate the virus or preclude transmission, but can control viral replication and prevent disease. High frequencies of CMV specific CD8 T cells are detectable in the peripheral blood of healthy individuals [1]. (Source: Biology of Blood and Marrow Transplantation)

The recent article by Hegab et al., titled "MRI-based determination of occlusal splint thickness for temporomandibular joint disk derangement: a randomized controlled clinical trial", attempted to use MRI to assess the most effective vertical thickness of the occlusal splint for the management of TMJ internal derangement1. The authors drew a conclusion that an increase in splint thickness was associated with an increase in anteroposterior condylar movements, anteroposterior disk movements, and vertical condylar movements, and led to improved clinical outcomes.

Authors: Türkoğlu G, Berkem R, Karakoç AE Abstract Antinuclear antibodies (ANA) are the autoantibodies that are produced against nuclear antigens in the cell nucleus and/or cytoplasm, and are one of the important diagnostic criteria in systemic autoimmune rheumatic diseases (SARD). Until today, several methods have been developed for detecting ANA's. However, indirect immunofluorescence (IIF) technique, that is also known as one of the oldest methods, is still the most commonly used one. Typically, anti-dense fine speckled 70/Lens epithelium derived growth factor p75 (anti-DFS70/LEDGF p75) autoantibody can be detected via IIF method where in HEp-2 (human larynx carcinoma) cells are used. The dense fine speckled (DFS) pattern method can be masked and remain unnoticed by the IIF m...

TIM-3 expression is supposedly up-regulated in tumor-bearing individuals via chronic antigenic stimulation of T cells. Considering the immunosuppressive nature of the tumor microenvironment, we investigated whether tumor-secreted molecules might enhance TIM-3 expression in Jurkat T cells. We observed that TIM-3 expression was increased by the activation of prostaglandin (PG) E2 and cyclic AMP (cAMP) signaling pathways.

In conclusion, this study compared the potential for reproduction of E.intestinalis in three human cell lines and monkey originated VERO cell line. This study demonstrated that cells derived from the tissues or organs where Microsporidia species causes disseminated infections could be infected by the parasitic spores in vitro. Additionally, the parasite can survive and propagate longer than six weeks. The authors believe that the results of this study will contribute to the further studies related to the parasite in the area of genetics, pharmacology, biochemistry, immunology and eradication studies.

We read with interest the article by Dr. Henderson "Updated guidelines on complex regional pain syndrome in adults." 1 The article provides an elegant summary of the Royal College of Physicians (RCP) current guidelines in the diagnosis and treatment of complex regional pain syndrome (CRPS) and recommends surgical intervention for the treatment of Type 2 CRPS (i.e. CRPS with a recognized nerve injury). However, it fails to identify the timing of such interventions. This is important considering the emerging paradigm shift in concepts of nerve pain, specifically 'centralization' of pain in neuroma patients with delayed presentations.

Burn scars are usually characterised by a combination of hypertrophic and keloid scars that are often very challenging to treat. They are a consequence of abnormal collagen deposition by fibroblasts exhibiting a hypersensitive response to growth factors.1 These scars can have a profound effect on patients both functionally and psychologically due to their poor cosmesis and debilitating symptoms.2 Currently there is no reliable or satisfactory treatment available to address the long-term sequelae of burns, however, more recently the use of laser-based treatments has been attributed to a paradigm shift in the management of burn scarring.

The authors need to be congratulated for their fine study on the use of Laser Speckle Contrast Imaging (LSCI) to predict flap necrosis in an experimental setting with a porcine pedicled flap model. LSCI has been repeatedly described for perfusion analysis in flap surgery. There has always been a demand to simplify or optimize intra- and postoperative flap monitoring, especially in free flap surgery. However, the individual techniques to postoperatively monitor free flaps vary considerably. In former studies from the early 1990ies with questionnaires ninety percent of microsurgeons reported to routinely use monitoring devices, with external and laser doppler having achieved greatest popularity.

Sanjuan-Cervero et al. 1 report that patients undergoing collagenase injections for the treatment of Dupuytren's contracture report less pain if a wrist block is performed first. Unfortunately the authors did not account for the pain of 10mls of mepivacaine being injected through two injections at the wrist.

We read with interest the article by Dr. Henderson "Updated guidelines on complex regional pain syndrome in adults." 1 The article provides an elegant summary of the Royal College of Physicians (RCP) current guidelines in the diagnosis and treatment of complex regional pain syndrome (CRPS) and recommends surgical intervention for the treatment of Type 2 CRPS (i.e. CRPS with a recognized nerve injury). However, it fails to identify the timing of such interventions. This is important considering the emerging paradigm shift in concepts of nerve pain, specifically 'centralization' of pain in neuroma patients with delayed presentations.

Several operative approaches and various implants for osseous fixation have been described to achieve four-corner fusion of the wrist. Given the discordance and to aid in further standardizing the technique, this study directly compares the outcomes of K-wire-, fusion-plate, and headless retrograde compressive screw-fixation to achieve four-corner arthrodesis.

Body contouring surgery following massive weight loss positively affects patient quality of life. However, the procedure is prone to complications. Here, we stratified complications time-wise. Furthermore, we examined whether the weight loss method — bariatric surgery or lifestyle changes — affected the frequency or severity of complications. In this single-centre retrospective analysis, we included 158 massive weight loss patients undergoing body contouring surgery between 2009 and 2015. We recorded 96 complications in 80 patients, with an overall rate of 51%.

I thank Drs Zeiderman and Pereira for their kind words and constructive comments. The Royal College of Physicians guidelines do not absolutely recommend surgery for all cases of type II CRPS, but recognize that it might be appropriate where nerve injury or entrapment are confidently diagnosed (e.g. with nerve conduction tests).

Burn scars are usually characterised by a combination of hypertrophic and keloid scars that are often very challenging to treat. They are a consequence of abnormal collagen deposition by fibroblasts exhibiting a hypersensitive response to growth factors.1 These scars can have a profound effect on patients both functionally and psychologically due to their poor cosmesis and debilitating symptoms.2 Currently there is no reliable or satisfactory treatment available to address the long-term sequelae of burns, however, more recently the use of laser-based treatments has been attributed to a paradigm shift in the management of burn scarring.

The authors need to be congratulated for their fine study on the use of Laser Speckle Contrast Imaging (LSCI) to predict flap necrosis in an experimental setting with a porcine pedicled flap model. LSCI has been repeatedly described for perfusion analysis in flap surgery. There has always been a demand to simplify or optimize intra- and postoperative flap monitoring, especially in free flap surgery. However, the individual techniques to postoperatively monitor free flaps vary considerably.

Nuclear theranostics functions as a bridge which connects targeted diagnosis to targeted therapy, just like Turkey functions as a geographical bridge which connects Asia to Europe. This unique geographical site of the country plays an important role with regard to introduction of novel scientific and technologic improvements, which originate from one continent to another, in the era of accelerated information. The first nuclear medicine practice in Turkey started in the beginning of 1950s with the first radioiodine treatment, which actually was a debut for nuclear theranostics in Turkey, years before many other countries in the world. For the time being, along with radioiodine treatment, many other theranostic applications such as I-131 MIBG treatment, Lu-177/Y-90 DOTA peptide treatment, Lu-177 PSMA treatment, Y-90 microsphere treatment, and bone palliative treatment are being performed in many centers countrywide. As science and technology improves, novel theranostic applications are eagerly awaited to be introduced in near future. This paper summarizes the story of nuclear theranostics in Turkey and aims to give an overview on the current status of theranostic applications in Turkey.
Targeted radionuclide therapy (TRT) is unique because of its efficacy and its theranostic feature in the era of precision medicine. So far, introduction of new TRT has not been going well in Japan due to several reasons including strict regulations, shortage of facilities for TRT, and insufficient reimbursement for TRT in clinic. Japanese community had several strategies to develop TRT in these 10 years, including the establishment of the National Conference for Nuclear Medicine Theranostics in which physicians, scientists, patients, people supporting patients, and industrial people gather. To promote TRT with supports from the government, the preparatory committee for the establishment of Japan Foundation of Medical Isotope Development (JAFMID) was launched. I would like to call TRT "Precision Nuclear Medicine." When we can add genomic information here, we can put it to new stage of cancer therapy. It is time for us.
Chloramine‐T (CAS no. 7080‐50‐4, syn. sodium p‐toluenesulfonchloramide) is a crystalline powder on a chlorine basis, commonly used as a sterilizer, antiseptic, disinfectant and chemical reagent. Sensitization is often work related. We report a case of an anaphylactic reaction to chloramine‐T.
Skin biopsies represent the gold standard for investigating skin immunology and biomarkers.1 However, biopsies cause discomfort, bleeding, minor scarring and, rarely, skin infections. Accordingly, non‐invasive techniques are increasingly popular in dermatological research.2,3 Among these, the tape‐strip method is commonly used for obtaining skin cells, but validation showing how many cell layers are removed with this sampling method has not yet adequately been performed. In this study, we determined the number of epidermal cell layers that is removed when tape‐stripping skin using two different adhesive materials.

Saliva is a bodily fluid transuded from gingival crevice fluid and blood and contains many proteins. Proteins in saliva have been studied as markers for periodontal diseases. Mass spectrometric analysis is applied to investigate biomarker proteins that are related to periodontitis.
Saliva samples were collected from 207 participants including 36 pairs matched for age, sex, and smoking who joined Yangpyeong health cohort. Periodontitis was defined by 2005 5th European guideline. Shotgun proteomics was applied to detect proteins from saliva samples. Principal component analysis and Ingenuity Pathway Analysis for canonical pathway and protein pathway were applied. Protein-protein interaction was also applied. Enzyme-linked immunosorbent assay (ELISA) was used to verify the candidate protein markers among another matched participants (n = 80).
Shotgun proteomics indicated that salivary S100A8 and S100A9 were candidate biomarkers for periodontitis. ELISA confirmed that both salivary S100A8 and S100A9 were higher in those with periodontitis compared to those without periodontitis (paired-t test, p < 0.05).
Our proteomics data showed that S100A8 and S100A9 in saliva could be candidate biomarkers for periodontitis. The rapid-test-kit using salivary S100A8 and S100A9 will be a practical tool for reducing the risk of periodontitis and promotion of periodontal health.
A rapid-test-kit using salivary biomarkers, S100A8 and S100A9, could be utilized by clinicians and individuals for screening periodontitis, which might reduce the morbidity of periodontitis and promote periodontal health.

Salivary gland cancers represent a rare group of tumors composed by over 20 histological subtypes. Initially treated as one single disease, its diagnosis, prognosis, and treatment are currently being stratified based on morphology. More recently, insight has been provided on the molecular characterization of each subtype, further improving diagnostic accuracy and paving the way for personalized therapy. In this article, we provide a comprehensive review of recent breakthroughs, preliminary results of novel therapy, and future directions on the treatment of these complex malignancies.
Progress in radiation treatment of head and neck squamous cell carcinoma (HNSCC) deserves the studies focused on molecular predictors that would help to enhance individually tailored treatment.
p16/epidermal growth factor receptor (EGFR)/cluster of differentiation‐44 (CD44) was immunohistochemically analyzed in 165 HNSCC patients.
In the entire group and the p16 negative cohort, better 3‐year overall survival and locoregional control correlated with p16 positivity, CD44, and EGFR negativity were observed. Combined analysis revealed the worst results in the CD44+/p16−, EGFR+/p16−, and EGFR+/CD44+ groups and in the EGFR+/CD44+ within p16 negative cohort. Multivariate analysis found tumor stage, Karnofsky index, p16, and CD44 as prognostic factors of overall survival and clinical stage, and p16 as a prognostic factor for locoregional control. Clinical stage and Karnofsky index affected overall survival and tumor stage. EGFR affected locoregional control in the p16 negative subgroup.
Our study confirmed the negative effect of CD44 and EGFR and the positive effect of p16 on radiotherapy results.
The radiotherapy can directly affect the bond strength of the adhesive materials, interfering in the prognosis of restorative treatments, which may be caused by chemical changes in dentin structure.
Twenty inferior homologues premolars were distributed in 2 groups (in vitro study) (n = 10): nonirradiated and irradiated. The specimens were submitted to the analysis of phosphate (ν1PO43−;ν2PO43−;ν4PO43−), carbonate (ν3CO32−), amide I, CH2, amide III, and amide I/III ratio by confocal Raman spectroscopy. Data were submitted to statistical analysis (T test, P < .05).
In intracanal dentin, the irradiated group had lower ν4PO43− values (1.23 ± 0.06) compared to nonirradiated group (1.40 ± 0.18) (P < .05), with no difference for ν1PO43− and ν2PO43 peaks (P > .05). The irradiated (1.56 ± 0.06) had lower carbonate, amide III (1.05 ± 0.19), and amide I/III ratio values (0.19 ± 0.06) compared to nonirradiated group (1.42 ± 0.10, 1.28 ± 0.24, and 0.31 ± 0.10, respectively) (P < .05). For medium dentin irradiated group (1.30 ± 0.12) had lower phosphate values compared to nonirradiated group (1.48 ± 0.22) (P < .05). In cementum, there was no statistical difference between the groups.
The radiotherapy was able to cause changes in ν4PO43−, carbonate, and amide III peaks of root dentin.
Transoral robotic surgery (TORS) has been utilized to deintensify treatment. No studies have measured swallow safety and efficiency, nor assessed the functional impact of TORS alone.
This prospective cohort underwent baseline and 1‐month postsurgery assessments including modified barium swallow evaluation, using the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) rating system, tongue range of motion assessment, the Performance Status Scale (PSS), and quality of life with the MD Anderson Dysphagia Inventory (MDADI).
All DIGEST safety scores were 0 (normal) at both time points. DIGEST efficiency scores were mildly impaired in 2 of 10 patients postsurgery. PSS scores revealed all patients were on regular diets, were 100% understandable, and were eating in public at both time points. Tongue Range of Motion scores were 100 of 100 at both time points. MDADI scores were not significantly different across time points.
Careful identification of patients can result in excellent outcomes following TORS. Future studies will examine longer follow‐up of speech, swallowing, and tongue function in patients undergoing TORS surgery.
Electrochemotherapy is an established treatment for cutaneous tumors. This study aimed at determining efficacy of electrochemotherapy in recurrent head and neck cancer.
Phase II clinical trial in patients with recurrent head and neck carcinomas with no curative treatment options. Electrochemotherapy was performed under general anesthesia. Primary endpoint was tumor response (CT scanning) evaluated at week 8. Secondary endpoints included biopsy results, MRI and fluorodeoxyglucose‐positron emission tomography scanning, safety, toxicity, pain score, and quality‐of‐life questionnaires.
Of 26 patients treated, 5 (19%) achieved complete response, 10 (39%) partial response, resulting in an objective response of 58%. Two responders remain without recurrence. No serious adverse events occurred during treatment. Four events occurred posttreatment: one bleeding episode, two episodes with mucosal swelling, and one patient died due to disease progression.
Electrochemotherapy is efficient against local recurrence of head and neck cancer with an overall response rate of 58%.
Kaposi's sarcoma (KS) is the most prevalent malignant neoplasia in human immunodeficiency virus positive (HIV+) patients for which the primary mode of management was chemotherapy.
We have presented the case of a newly diagnosed HIV+ male patient who was diagnosed with a pedunculated nodule in the anterior region of the hard palate, measuring 3.5 cm in diameter and with 2 months of evolution.
Histopathological examination confirmed the clinical hypothesis of KS. Soon after the diagnosis, the patient started using combined antiretroviral therapy (Biovir and Kaletra), presenting a significant reduction of the lesion after 4 weeks. With 1.5 cm in diameter, the lesion was surgically removed. The patient was followed‐up for 10 years without any recurrence.
In antiretroviral‐naive patients with a well‐preserved immune system, the use of cART may be efficient in reducing the progression of the KS lesions, thus avoiding the use of chemotherapeutic agents.
To develop and validate practical prognostic indexes (PIs) for predicting the prognosis and response to postoperative adjuvant therapy in patients with oral squamous cell carcinoma (OSCC).
A large cohort of 1071 OSCC patients were randomized to either training set (N = 708) or validation set (N = 363). Three types of PIs were developed according to the nomogram scores, β coefficients and excess hazard ratios, respectively. Restricted cubic spline was used to demonstrate the relationship between PIs and the risks of death.
First, a nomogram was developed incorporating age at diagnosis, smoking status, clinical stage, tumor differentiation, lymph node status, comorbidity, and neutrophil to lymphocyte ratio levels. Then, three PIs were established with high survival predictive ability, and were superior to AJCC staging system (all P < .05). The risks of death were escalated continuously with the increasing number of PIs. Interestingly, adjuvant chemoradiotherapy was positively associated with poor overall survival in patients with low PIs, but exerted a beneficial effect on patients with high PIs.
Combined nomogram with further established PIs not only predicts the survival probability of OSCC patients, but also continuously quantifies the risk of death. High PIs could predict a beneficial response to adjuvant chemoradiotherapy, whereas low PIs indicate an unfavorable response.
The updated AJCC Cancer Staging Manual groups all p16‐positive oropharyngeal squamous cell carcinoma (OPSCC) with unilateral nodal involvement within 6 cm into the new clinical N1 classification, consolidating a heterogeneous group of disease with varying radiographic findings.
A central radiological review was conducted identifying 233 patients with stage I node‐positive (cT1‐2N1) disease who underwent definitive concurrent chemoradiation. Factors evaluated included lymph node size, low‐neck lymphadenopathy, retropharyngeal lymphadenopathy, overt radiographic extracapsular extension, and matted lymphadenopathy.
On multivariate analysis adjusted for age, smoking history, and chemotherapy regimen, low‐neck lymphadenopathy (hazard ratio (HR) = 6.55; P < .001) and retropharyngeal lymphadenopathy (HR = 3.36; P = .009) predicted for inferior progression‐free survival (PFS). low‐neck lymphadenopathy (HR = 6.38; P = .001) and retropharyngeal lymphadenopathy (HR = 3.32; P = .02) also predicted for inferior overall survival (OS). All other radiographic characteristics showed no prognostic impact for PFS or OS.
This analysis suggests that caution should be advised against de‐intensification efforts among patients with stage I node‐positive p16‐positive OPSCC with low‐neck lymphadenopathy or retropharyngeal lymphadenopathy.
We investigated the survival of patients with a p16‐positive N3 oropharyngeal squamous cell carcinoma (OPSCC) and the prognostic significance of patient, tumor, and treatment characteristics.
We retrospectively reviewed the data of patients treated at our Cancer Center for a p16‐positive N3 OPSCC between 2003 and 2016. End points were overall survival (OS) and progression‐free survival (PFS).
A total of 29 patients were included. The 5‐year OS and PFS were 67.5% and 59.1%, respectively. Smoking history above 10 pack‐years and the absence of human papillomavirus DNA were associated with worse OS (P = .02 and P = .03, respectively) and PFS (P = .02 and P = .02, respectively). Induction chemotherapy or radical neck dissection were not associated with different treatment outcomes.
Patients with an N3 p16‐positive oropharyngeal cancer in our series had a 5‐year OS rate of 67.5%. Smoking history and viral DNA were prognostic factors associated with survival.
High prevalence of comorbidity in head and neck squamous cell carcinoma (HNSCC) often lead to suboptimal treatment. The presence study aims to evaluate the presence of comorbidity, its impact on therapeutic decision making, treatment compliance, and overall survival in HNSCC.
Five hundred eighteen patients with nonmetastatic HNSCC, elder than 18 years of age, without any prior history of cancer or anticancer treatment in the last 5 years were evaluated using Adult Comorbidity Evaluation 27 (ACE 27) index.
Two hundred ninety three (56.6%) patients had comorbidity, and 20.6% had deviation from the ideal treatment plan. Higher grade of comorbidity led to less likely completion of guideline‐concordant therapy (moderate ACE 27 vs none: odds ratio [OR] 0.46, 95% confidence interval [CI] 0.26‐0.82, P < .01*; severe ACE 27 vs none: OR 0.23, 95% CI 0.08‐0.57, P < .01*). Patients who completed guideline‐concordant treatment had the best outcomes as compared to those who could not (median survival: not reached vs 9.56 months, hazard ratio 3.66, 95% CI: 2.8‐4.79; P < .01*).
Presence of increasing severity of comorbidity in HNSCC influences therapeutic decision making. Survival outcomes are poorer in patients receiving guideline‐discordant treatment.
Chewing ability is often compromised in patients with oral cancer. The aim of this study was to identify which factors affect masticatory performance in these patients.
Patients with primary oral cancer were assessed for up to 5 years after primary treatment. Healthy controls were assessed once. A mixed‐model analysis was performed, with masticatory performance as outcome measure.
A total of 123 patients were included in the study. Factors positively associated with masticatory performance were number of occlusal units (OU), having functional dentures, and maximum mouth opening (MMO). The impact of tumor location and maximum bite force (MBF) differed per assessment moment. Masticatory performance declined for up to 1 year but recovered at 5 years after treatment.
Masticatory performance in patients treated for oral cancer is affected by MBF, MMO, number of OU, and dental status. These should be the focus of posttreatment therapy.
Transoral robotic surgery (TORS) has been utilized to deintensify treatment. No studies have measured swallow safety and efficiency, nor assessed the functional impact of TORS alone.
This prospective cohort underwent baseline and 1‐month postsurgery assessments including modified barium swallow evaluation, using the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) rating system, tongue range of motion assessment, the Performance Status Scale (PSS), and quality of life with the MD Anderson Dysphagia Inventory (MDADI).
All DIGEST safety scores were 0 (normal) at both time points. DIGEST efficiency scores were mildly impaired in 2 of 10 patients postsurgery. PSS scores revealed all patients were on regular diets, were 100% understandable, and were eating in public at both time points. Tongue Range of Motion scores were 100 of 100 at both time points. MDADI scores were not significantly different across time points.
Careful identification of patients can result in excellent outcomes following TORS. Future studies will examine longer follow‐up of speech, swallowing, and tongue function in patients undergoing TORS surgery.
The C‐reactive protein/albumin (CRP/Alb) ratio has been recently established as a prognostic indicator in various cancer types. However, few reports regarding the prognostic value of the CRP/Alb ratio in head and neck cancer exist. This study aimed to investigate the significance of the CRP/Alb ratio in clinical outcomes after invasive surgery involving laryngectomy for hypopharyngeal and laryngeal cancer.
We evaluated 56 patients who underwent total laryngectomy or total pharyngolaryngectomy between 2003 and 2012. Univariate and multivariate analyses were retrospectively performed to examine the prognostic value of the CRP/Alb ratio in these patients.
The optimal cutoff value of the CRP/Alb ratio was 0.32. Multivariate analysis showed that the CRP/Alb ratio was a significant and independent predictor of poor overall and disease‐free survival.
The CRP/Alb ratio may be a novel and useful indicator for predicting postoperative outcomes in patients with hypopharyngeal and laryngeal cancer.
Progress in radiation treatment of head and neck squamous cell carcinoma (HNSCC) deserves the studies focused on molecular predictors that would help to enhance individually tailored treatment.
p16/epidermal growth factor receptor (EGFR)/cluster of differentiation‐44 (CD44) was immunohistochemically analyzed in 165 HNSCC patients.
In the entire group and the p16 negative cohort, better 3‐year overall survival and locoregional control correlated with p16 positivity, CD44, and EGFR negativity were observed. Combined analysis revealed the worst results in the CD44+/p16−, EGFR+/p16−, and EGFR+/CD44+ groups and in the EGFR+/CD44+ within p16 negative cohort. Multivariate analysis found tumor stage, Karnofsky index, p16, and CD44 as prognostic factors of overall survival and clinical stage, and p16 as a prognostic factor for locoregional control. Clinical stage and Karnofsky index affected overall survival and tumor stage. EGFR affected locoregional control in the p16 negative subgroup.
Our study confirmed the negative effect of CD44 and EGFR and the positive effect of p16 on radiotherapy results.
We investigated the survival of patients with a p16‐positive N3 oropharyngeal squamous cell carcinoma (OPSCC) and the prognostic significance of patient, tumor, and treatment characteristics.
We retrospectively reviewed the data of patients treated at our Cancer Center for a p16‐positive N3 OPSCC between 2003 and 2016. End points were overall survival (OS) and progression‐free survival (PFS).
A total of 29 patients were included. The 5‐year OS and PFS were 67.5% and 59.1%, respectively. Smoking history above 10 pack‐years and the absence of human papillomavirus DNA were associated with worse OS (P = .02 and P = .03, respectively) and PFS (P = .02 and P = .02, respectively). Induction chemotherapy or radical neck dissection were not associated with different treatment outcomes.
Patients with an N3 p16‐positive oropharyngeal cancer in our series had a 5‐year OS rate of 67.5%. Smoking history and viral DNA were prognostic factors associated with survival.
