Purpose: To retrospectively report the outcome of head and neck cancer patients following re-irradiation. Patients and Methods: A total of 51 patients with recurrent or second primary head and neck cancer received re-irradiation at Leuven University Hospital. Survival and locoregional control were calculated. Doses to organs at risk were retrieved from dose-volume histograms. Radiation-related toxicities were reported. Results: The 2-year actuarial overall survival rate was 30%. On univariate analysis, surgery before re-irradiation and high radiation dose were associated with superior survival. Grade 3 acute and grade 3 or more late toxicity occurred in respectively 29.4% and 35.3% of the patients. Conclusion: Re-irradiation in head and neck cancer patients is feasible with acceptable late toxicity, although the survival remains poor. (orig.)

Late complications of head and neck cancer survivors include neck muscle atrophy and soft-tissue fibrosis. We present an autopsy case of neck muscle atrophy and soft-tissue fibrosis (sternocleidomastoid, omohyoid, digastric, sternohyoid, sternothyroid, and platysma muscles) within the radiation field after modified radical neck dissection type I and postoperative radiotherapy for floor of mouth cancer. A 70-year-old man underwent primary tumor resection of the left floor of mouth, left marginal mandibulectomy, left modified radical neck dissection type I, and reconstruction with a radial forearm free flap. The patient received adjuvant radiotherapy. The dose to the primary tumor bed and involved neck nodes was 63 Gy in 35 fractions over 7 weeks. Areas of subclinical disease (left lower neck) received 50 Gy in 25 fractions over 5 weeks. Adjuvant chemotherapy was not administered.

Objective Pain is a strong contributor to cancer patients’ quality of life. The objective of this study was to determine predictors of pain 1 year after the diagnosis of head and neck cancer. Design Prospective, multi-site cohort study. Setting Three academically-affiliated medical centers. Patients Previously untreated patients with carcinoma of the upper aerodigestive tract (n=374). Main Outcome Measures Participants were surveyed pre-treatment and 1 year thereafter. Multivariate analyses were conducted to determine predictors of the SF-36 bodily pain score 1 year after diagnosis. Results The mean SF-36 bodily pain score at 1 year was 65, compared to 61 at diagnosis (p=.004), compared to 75 among population norms (lower scores indicate worse pain). Variables independently associated with pain included pre-treatment pain score (p<0.001), less education (p=0.02), neck dissection (p=0.001), feeding tube (p=0.05), xerostomia (p<0.001), depressive symptoms (p<0.001), taking more pain medication (p<0.001), less physical activity (p=.02), and poor sleep quality (p=0.006). Current smoking and problem drinking were marginally significant (p=0.07 and 0.08, respectively). Conclusions Aggressive pain management may be indicated for head and neck cancer patients who undergo neck dissections, complain of xerostomia, require feeding tubes, and have medical comorbidities. Treatment of modifiable risk factors such as depression, poor sleep quality, tobacco and alcohol abuse may also reduce pain and improve quality of life among head and neck cancer patients.

Following the increasing desire of many patients to keep the form and function of speech and swallowing, interstitial brachytherapy has become the main treatment for head and neck cancer. In addition, aged and physically handicapped patients who are refused general anesthesia have come to be referred to our clinic to receive less invasive and curative treatment. In the field of brachytherapy for head and neck cancers, less complicated and more superior treatment results have been achieved following the introduction of spacers, computer dosimetry and so on. As a result of these efforts, treatment results have come to fulfill the desire of patients and their families. During the past 43 years from 1962 to 2005, we have treated over 2, 100 patients of head and neck cancer including 850 with stage I·II oral tongue carcinoma by brachytherapy and acquired a lot of important and precious data including the treatment results, multiple primary cancers as well as radiation-induced cancers.

The optimal method of screening for thyroid cancer in survivors of childhood and young adult cancer exposed to neck radiation remains controversial. Outcome data for a physical exam-based screening approach are lacking. We conducted a retrospective review of adult survivors of childhood and young adult cancer with a history of neck radiation followed in the Adult Long-Term Follow-Up Clinic at Memorial Sloan Kettering between November 2005 and August 2014. Eligible patients underwent a physical exam of the thyroid and were followed for at least 1 year afterwards. Ineligible patients were those with prior diagnosis of benign or malignant thyroid nodules. During a median follow-up of 3.1 years (range 0-9.4 years), 106 ultrasounds and 2277 physical exams were performed among 585 patients. Forty survivors had an abnormal thyroid physical exam median of 21 years from radiotherapy; 50% of those with an abnormal exam were survivors of Hodgkin lymphoma, 60% had radiation at ages 10-19, and 53% were female. Ultimately, 24 underwent fine needle aspiration (FNA). Surgery revealed papillary carcinoma in seven survivors; six are currently free of disease and one with active disease is undergoing watchful waiting. Among those with one or more annual visits, representing 1732 person-years of follow-up, no cases of thyroid cancer were diagnosed within a year of normal physical exam. These findings support the application of annual physical exam without routine ultrasound for thyroid cancer screening among survivors with a history of neck radiation. Survivors with a history of neck radiation may not require routine thyroid ultrasound for thyroid cancer screening. Among adult survivors of childhood and young adult cancer with a history of radiation therapy to the neck, annual physical exam is an acceptable thyroid cancer screening strategy.

Data on smoking and second cancer risk among cancer survivors are limited. We assessed associations between smoking before first cancer diagnosis and risk of second primary smoking-associated cancers among survivors of lung (stage I), bladder, kidney, and head/neck cancers. Data were pooled from 2,552 patients with stage I lung cancer, 6,386 with bladder cancer, 3,179 with kidney cancer, and 2,967 with head/neck cancer from five cohort studies. We assessed the association between prediagnostic smoking and second smoking-associated cancer risk with proportional hazards regression, and compared these estimates to those for first smoking-associated cancers in all cohort participants. Compared with never smoking, current smoking of ≥ 20 cigarettes per day was associated with increased second smoking-associated cancer risk among survivors of stage I lung (hazard ratio [HR] = 3.26; 95% CI, 0.92 to 11.6), bladder (HR = 3.67; 95% CI, 2.25 to 5.99), head/neck (HR = 4.45; 95% CI, 2.56 to 7.73), and kidney cancers (HR = 5.33; 95% CI, 2.55 to 11.1). These estimates were similar to those for first smoking-associated cancer among all cohort participants (HR = 5.41; 95% CI, 5.23 to 5.61). The 5-year cumulative incidence of second smoking-associated cancers ranged from 3% to 8% in this group of cancer survivors. Understanding risk factors for second cancers among cancer survivors is crucial. Our data indicate that cigarette smoking before first cancer diagnosis increases second cancer risk among cancer survivors, and elevated cancer risk in these survivors is likely due to increased smoking prevalence. The high 5-year cumulative risks of smoking-associated cancers among current smoking survivors of stage I lung, bladder, kidney, and head/neck cancers highlight the importance of smoking cessation in patients with cancer. © 2014 by American Society of Clinical Oncology.

Human papillomavirus (HPV) is one of the most widely publicized and researched pathogenic DNA viruses. For decades, HPV research has focused on transforming viral activities in cervical cancer. During the past 15 years, however, HPV has also emerged as a major etiological agent in cancers of the head and neck, in particular squamous cell carcinoma. Even with significant strides achieved towards the screening and treatment of cervical cancer, and preventive vaccines, cervical cancer remains the leading cause of cancer-associated deaths for women in developing countries. Furthermore, routine screens are not available for those at risk of head and neck cancer. The current expectation is that HPV vaccination will prevent not only cervical, but also head and neck cancers. In order to determine if previous cervical cancer models for HPV infection and transformation are directly applicable to head and neck cancer, clinical and molecular disease aspects must be carefully compared. In this review, we briefly discuss the cervical and head and neck cancer literature to highlight clinical and genomic commonalities. Differences in prognosis, staging and treatment, as well as comparisons of mutational profiles, viral integration patterns, and alterations in gene expression will be addressed.

1988-01-01

The role of precautionary radiotherapy of the neck in laryngeal cancers (exept T1-T2 glottic and some T1 supraglottic cancers) NO at the clinical staging was investigated. Two-hundred and fifty-three patients were examined: 143 were irradiated only on T, and 110 also on the neck. Radiotherapy of the neck in the latter group was performed either by means of two large opposed fields of photon beams including T and N, or by means of fields of photon beams on T and electron beams (8x12 cm 2 average) on the neck, to quite exclude any risks for the spinal cord. The dose was 45-50 Gy (2 Gy/fraction/day; 5 fraction/week) in 4-5 weeks. A comparison of the results obtained in the two groups, in terms of survival-rate and relapse-free time, indicates that radiotherapy reduces the change of relapses on N (6.1% vs. 14.62% at 3 years; p=0.04) and improves the patient's survival chances (82.5% vs. 68.4% at 3 years; and 80.8% vs. 63.4% at 5 years). Our data were then compared with literature data on the importance of N field size in radiation treatment. As a rule, some authors enlarge the field to be treated to a total nodal neck irradiation, but their results are not significally different from those we obtained with 8x12 cm 2 field size

Full Text Available Objective: Cancer affects the head and neck region frequently and leads to significant morbidity and mortality. Oncolytic viral therapy has the potential to make a big impact in cancers that affect the head and neck. We intend to review the current state of oncolytic viruses in the treatment of cancers that affect the head and neck region. Method: Data sources are from National clinical trials database, literature, and current research. Results: There are many past and active trials for oncolytic viruses that show promise for treating cancers of the head and neck. The first oncolytic virus was approved by the FDA October 2015 (T-VEC, Amgen for the treatment of melanoma. Active translational research continues for this and many other oncolytic viruses. Conclusion: The evolving field of oncolytic viruses is impacting the treatment of head and neck cancer and further trials and agents are moving forward in the coming years.

Several trials have shown that cupping might be an effective treatment for chronic nonspecific neck pain, but little is known about the long-term effectiveness. This study aimed to investigate long-term effects of a short series of cupping; therefore additional follow-up measurements were conducted 2 years after completion of 3 studies. Participants from 3 randomized waitlist controlled trials on cupping for chronic nonspecific neck pain were followed 2 years after treatment. Outcome measures included neck pain intensity (100 mm Visual Analog Scale; VAS), functional disability (Neck Disability Index, NDI), and health-related quality of life (Short Form 36 Health Survey Questionnaire; SF-36). 133 of 150 patients had received cupping treatment and were contacted; 82 of them (61.7%) returned the follow-up questionnaires. No effect was found for neck pain intensity, but for physical function (∆ NDI: -3.15; 95% CI: -5.89; -0.41; p = 0.025) and quality of life (∆ physical component summary: 2.97; 95% CI: 0.97; 4.97; p = 0.004; ∆ bodily pain: 14.53; 95 % CI: 9.67; 19.39; p cupping effect was 8.9 ± 8.7 months with 16 patients reporting that neck pain had not yet reached the level before cupping. The majority of the patients did not continue cupping therapy, mostly due to lack of providers, costs or loss of interest. A series of cupping treatments did not influence neck pain intensity on the longer term, however significant increases were found for physical function and quality of life in patients with chronic nonspecific neck pain. Due to the considerable drop-out rate conclusions are limited. There is evidence suggesting that cupping treatment might have sustainable effects in some patients. Further randomized controlled trials with long-term follow-up are urgently needed for conclusive judgment of long-term effectiveness. © 2013 S. Karger GmbH, Freiburg.

2010-04-01

Studies show 60% of patients with newly diagnosed Head & Neck Squamous Cell Cancer in Ireland, present with advanced disease. A poor level of knowledge and awareness among the public of Head & Neck Cancer, is an important consideration in the often delayed presentation for medical attention in many of these cases. Our study surveyed 200 members of the public to assess their knowledge and awareness of Head & Neck Cancer. One hundred and forty (70%) of respondents had never encountered the term "Head & Neck Cancer". One hundred and forty six (73%) failed to identify excessive alcohol consumption as a risk factor. Less than 100 (50%) would have concern about persisting hoarseness or a prolonged oral ulcer. An urgent need exists to raise awareness of Head & Neck Cancer among the public in Ireland.

Regional lymph node metastases significantly influence the prognosis of patients with parotid cancer. To assess our indications of elective neck dissection and postoperative radiotherapy for parotid cancer, a retrospective chart review was performed. Between 2001 and 2009, 35 patients with parotid cancer were initially treated at our department. The median follow-up was 30 months (range, 10-90 months). Out of all patients, 31 (89%) patients were preoperatively diagnosed as malignant, while 4 (11%) patients were initially diagnosed as benign. Mucoepidermoid carcinoma was the most common histological type (10 patients). Twenty-two tumors (63%) were pathologically diagnosed as high-grade. The numbers of patients with Stages I, II, III, and IVA were 3, 10, 7, and 15, respectively. Ipsilateral neck dissection (Level II-V) was performed in seven patients with clinically positive neck metastasis (cN+), and in ten patients without lymph node metastasis who had T4 disease, high-grade malignancy, or positive neck (Level II) metastasis during intraoperative evaluation. Postoperative radiotherapy was performed in 24 patients with pathological T4, high-grade malignancy, positive surgical margin, multiple neck metastasis and/or extranodal extension (ENI). Seven of 28 (25%) patients with clinically N0 had pathologically positive neck metastasis (pN+). Regional recurrence developed in one patient with high-grade malignancy and ENI (T4N2b). Disease-specific survival rates for Stages I, II, III, and IVA at 3 years were 100%, 73%, 100%, and 37%, respectively. Loco-regional control rates for pN0 (21 patients) and pN+ (14 patients) at 3 years were 90% and 95%, respectively. Our present favorable loco-regional control supported our current indications of elective neck dissection and postoperative radiotherapy. We also recommend intraoperative biopsy of level IIB nodes to study the need for elective neck dissection. (author)

Validity and QOL of neck dissection preceding radiation therapy for hypopharyngeal cancer

Uemura, Hirokazu; Yoshino, Kunitoshi; Fujii, Takashi; Suzuki, Motoyuki

2009-01-01

Thirty-one cases of hypopharyngeal cancer with neck dissection preceding radiation and 16 cases of hypopharyngeal cancer with neck dissection for locoregional recurrences after radiation were reviewed in order to make comparative evaluations of difficulty in surgical operation, postoperative complications, laryngeal preservation rate, and cause specific 5-year survival rate retrospectively. And quality of life (QOL) after neck dissection was additionally evaluated through the questionnaire. Since neck dissection preceding radiation for hypopharyngeal cancer may be superior to neck dissection for radiation failure, with easy surgical approach an non-lymphoid tissue preservation, that modality can be a reasonable choice of treatment for patients with nodal lesions, which are probably difficult to treat with radiation alone. Even though further investigation on QOL questionnaire is necessary, this modality can make a contribution to the neck and shoulder condition after neck dissection. (author)

Cetuximab And The Head And Neck Squamous Cell Cancer.

2018-01-12

The head and neck squamous cell cancer (HNSCC) is the most common type of head and neck cancer (more than 90%), and all over the world more than a half million people have been developing this cancer in the last years. This type of cancer is usually marked by a poor prognosis with a really significant morbidity and mortality. Cetuximab received early favor as an exciting and promising new therapy with relatively mild side effect, and due to this received authorization in the 2004 from the European Medicines Agency (EMA) and in the 2006 from the Food and Drug Association (FDA) for the treatment of patients with squamous cell cancer of the head and neck in combination with radiation therapy for locally advanced disease. In this work we will review the application and the efficacy of the Cetuximab in the treatment of the HNSCC.

Head and neck cancer: Radiotherapeutic precepts in the management of the neck

International Nuclear Information System (INIS)

Million, R.R.; Cassisi, N.J.; Parsons, J.T.; Mendenhall, W.M.

1986-01-01

The authors provide a series of statements regarding the use of radiotherapy and surgery for metastatic squamous cancer to the neck. Some of these precepts are established facts requiring no additional documentation - for example, the combination of radiation and neck dissection for effective treatment of N2B neck disease or for subclinical disease, depending on extracapsular spread. Other precepts of the authors are not as generally accepted by head and neck surgeons, such as the mandatory staging of neck dissections following curative radiation therapy or the routine use of computerized tomography (CT) to confirm pathologic adenopathy. Most of the authors' precepts are supported by a combination of their personal clinical experience and hard data from the University of Florida, Gainesville

Extracellular matrix metalloproteinase inducer (EMMPRIN), a plasma membrane protein of the immunoglobulin (Ig) superfamily, has been reported to promote cancer cell invasion and metastasis in several human malignancies. However, the roles of the different EMMPRIN isoforms and their associated mechanisms in head and neck cancer progression remain unknown. Using quantitative real-time PCR, we found that EMMPRIN isoform 2 (EMMPRIN-2) was the only isoform that was overexpressed in both head and n...

''Watch-and-see'' policy for the clinically positive neck in head and neck cancer treated with chemoradiotherapy

2006-01-01

Chemoradiotherapy (CRT) is becoming more widely used for head and neck cancer. However, there are conflicting theories regarding the best management options for patients with advanced nodal disease. From 1990 to 1999, we treated 96 patients with N1-N2 neck disease by concomitant CRT for organ preservation, using weekly carboplatin or a low daily dose of cisplatin, followed by a ''watch-and-see'' policy for the neck. In the present study, we retrospectively analyzed the treatment outcome in 63 of these patients who received definitive CRT for primary and neck diseases and were monitored for neck disease for more than 2 years. In 12 of the 22 (55%) N1 patients, CRT successfully controlled the neck disease. CRT was successful in 18 of the 41(44%) patients with N2 disease. In 6 (60%) of 10 patients with residual or recurrent N1 disease, salvage surgery was successful. Of the 23 patients with residual or recurrent N2 disease, salvage surgery was successful in 8 patients (35%). The group of patients who showed a clinical complete response (CCR) to CRT had an overall survival rate of 62.4% (33 patients), whereas for those with a less than complete response (< CCR), the figure was 13.3% (30 patients; P<0.001). Among the < CCR-neck group, patients who underwent neck dissection (ND) as well (n=20) did not have a significantly better overall survival than those who did not undergo ND (n=10; P=0.069). We propose a treatment plan for neck disease that involves observing the neck closely following CRT. ND should be planned only when there is evidence that neck disease exists. (author)

Pocket Proteins Suppress Head and Neck Cancer

Shin, Myeong-Kyun; Pitot, Henry C.; Lambert, Paul F.

2012-01-01

Head and neck squamous cell carcinomas (HNSCC) is a common cancer in humans long known to be caused by tobacco and alcohol use, but now an increasing percentage of HNSCC is recognized to be caused by the same human papillomaviruses (HPVs) that cause cervical and other anogenital cancers. HPV-positive HNSCCs differ remarkably from HPV-negative HNSCCs in their clinical response and molecular properties. From studies in mice, we know that E7 is the dominant HPV oncoprotein in head and neck cancer. E7 is best known for its ability to inactivate pRb, the product of the retinoblastoma tumor susceptibility gene. However loss of pRb function does not fully account for E7’s potency in causing head and neck cancer. In this study, we characterized the cancer susceptibility of mice deficient in the expression of pRb and either of two related “pocket” proteins, p107 and p130, that are also inactivated by E7. pRb/p107 deficient mice developed head and neck cancer as frequently as do HPV16 E7 transgenic mice. The head and neck epithelia of the pRb/p107 deficient mice also displayed the same acute phenotypes and biomarker readouts as observed in the epithelia of E7 transgenic mice. Mice deficient for pRb and p130 in their head and neck epithelia showed intermediate acute and tumor phenotypes. We conclude that pRb and p107 act together to efficiently suppress head and neck cancer, and are therefore highly relevant targets of HPV16 E7 in its contribution to HPV-positive HNSCC.

Amin, Mohamed

2010-08-01

The objectives of the study were: first, to determine the prevalence of traditional medicine (TM) and complementary and alternative medicine (CAM) use in head and neck cancer patients in Ireland; second, to educate ourselves on the plethora of CAM\\/TM options available to patients outside the dominion of conventional medicine. The study design consisted of a cross-sectional survey carried out in three head and neck cancer centres. Self-administered questionnaires were distributed to 110 head and neck cancer patients attending the three cancer centres and data were collected for statistical analysis. A total of 106 patients completed the questionnaire; 21.7% of the participants used CAM\\/TM since their diagnosis with head and neck cancer. CAM\\/TM usage was higher in female (34.3%) than in male patients (16.2%). CAM\\/TM use was more common in the 41-50-year age group, in patients with higher educational levels and those holding strong religious beliefs, and also in married than single patients. The most common types of CAM\\/TM used were spiritual and laying on of hands. The most common reasons reported for using CAM\\/TM were to counteract the ill effects of treatment and increase the body\\'s ability to fight cancer. Sources of information on CAM\\/TM were friends (65%), family (48%) and media (21%). This survey reveals a high prevalence of CAM\\/TM use in head and neck cancer patients, hence emphasising the need for otolaryngologists to educate themselves on the various therapies available to be able to provide informative advice. There is an urgent need for evidence-based investigation of various CAM\\/TM therapies currently offered to patients.

Head and neck cancer, for which the diagnosis and treatment are often surgical, comprises a substantial proportion of the burden of disease in South Asia. Further, estimates of surgical volume suggest this region faces a critical shortage of surgical capacity. We aimed to estimate the total economic welfare losses due to the morbidity and mortality of head and neck cancer in India, Pakistan, and Bangladesh for 1 year (2010). We used publicly available estimates from the Institute for Health Metrics and Evaluation regarding the morbidity and mortality of head and neck cancer in India, Pakistan, and Bangladesh, along with an economic concept termed the value of a statistical life, to estimate total economic welfare losses due to head and neck cancer in the aforementioned countries in the year 2010. The counterfactual scenario is absence of disease. Sensitivity analyses were done with regard to how the value of a statistical life changes with income. In 2010, the most conservative estimate of economic welfare losses due to head and neck cancer in the three studied countries is US$16·9 billion (2010 USD, PPP), equivalent to 0·26% of their combined gross domestic product (GDP). The welfare losses experienced by the population younger than 70 years of age accounted for US$15·2 billion (90% of the total losses). When adjusted for the size of their respective economies, Bangladesh, the poorest of the three countries, incurred the greatest loss (US$930 million), equivalent to 0·29% of its GDP. India and Pakistan experienced welfare losses of US$14·1 billion and US$1·9 billion, respectively. These figures are equivalent to 0·26% of the GDP for both countries. Oropharyngeal and hypopharyngeal cancer made up the largest share of the total burden at 39% (US$6·6 billion), followed closely by oral cavity cancer at 34% (US$5·7 billion). The burden of non-communicable diseases, to which cancer contributes greatly, is growing at a rapid pace in South Asia. Head and neck

A speech therapist performs swallowing rehabilitation in this hospital because concurrent chemoradiotherapy (CCRT) for head and neck cancer is commonly associated with, dysphagia. An evaluation of oral mucositis and dysphagia after CCRT was conducted to determine the relationship between swallowing rehabilitation and swallowing disability. A total of 51 patients (44 males and 7 females) with a mean age of 63 years (range, 39 to 80), underwent CCRT with or without neck dissection between April 2008 and November 2009. Oral mucositis and dysphagia were graded at the end of CCRT according to Common Terminology Criteria for Adverse Events (CTCAE), version 4.0. Seventeen of 51 patients underwent swallowing rehabilitation, exercise and education on muscle strengthening programs before and during CCRT. The average grades of oral mucositis of patients with nasopharyngeal, oropharyngeal, hypopharyngeal, and laryngeal cancer patients were 1.8, 2.1, 1.8, and 0.8, respectively. There was a lower incidence of oral mucositis in patients with laryngeal cancer than in those with oropharyngeal or hypopharyngeal cancer. The average grades of dysphagia of patients with nasopharyngeal, oropharyngeal, hypopharyngeal, and laryngeal cancer were 2.4, 2.7, 2.2, and 1.2. Dysphagia was most severe in the patients with oropharyngeal cancer, while it was minimal in those with laryngeal cancer. Seventeen diligent patients that underwent swallowing rehabilitation every day rarely developed severe dysphagia. (author)

We established the level of awareness of risk factors and early symptoms of head and neck cancer among American Indians in South Dakota and determined whether head and neck cancer screening detected clinical findings in this population. We used the European About Face survey. We added questions about human papillomavirus, a risk factor for head and neck cancer, and demographics. Surveys were administered at 2 public events in 2011. Participants could partake in a head and neck cancer screening at the time of survey administration. Of the 205 American Indians who completed the survey, 114 participated in the screening. Mean head and neck cancer knowledge scores were 26 out of 44. Level of education was the only factor that predicted higher head and neck cancer knowledge (b = 0.90; P = .01). Nine (8%) people had positive head and neck cancer screening examination results. All abnormal clinical findings were in current or past smokers (P = .06). There are gaps in American Indian knowledge of head and neck cancer risk factors and symptoms. Community-based head and neck cancer screening in this population is feasible and may be a way to identify early abnormal clinical findings in smokers.

Chronic exposure to heavy metals has long been recognized as being capable to increase head and neck cancer incidence among exposed human populations. Head and neck cancer is a significant public health issue in Tunisia. The aim of the present study was to evaluate the concentrations of As, Cd, Cr and Ni in healthy and tumor tissues of head and neck cancer patients. Metal concentrations were determined in tumor and healthy tissues of 101 head and neck cancer patients, using Atomic Absorption Spectrometry. The As, Cd, Cr, and Ni levels in tumor tissues were 3.4, 2.5, 1.3 and 1.5 times higher than those of healthy tissues (p 60 years) in both never-smokers and ever-smokers (< 20 and ≥ 20 pack per year). Healthy tissue Cd levels were negatively associated with age in those three groups of smokers. The highest Cd and Cr concentrations among both workers and non-workers were observed in tumor tissues. The Cd and Cr in tissues of farmers, bricklayers and painters were all significantly higher among the workers as compared with the non-workers group. Tissue metal levels have increased due to smoking and occupational exposure. Heavy metal exposure via tobacco smoking and occupational exposures may increase the risk of head and neck in the Tunisian population. - Highlights: ► Heavy metal levels in tumor tissues were higher than those in healthy tissues. ► Tumor tissue Cd levels were positively associated with age in smokers. ► Tumor tissue metal levels were higher in men than in women. ► The highest Cd and Cr concentrations among workers were observed in tumor tissues. ► Heavy metal exposure via occupational exposures may increase the risk of HNC

Purpose: this study was undertaken to evaluate the efficacy of two regimens of chemoradiotherapy in the treatment of locally advanced head and neck cancer. Methods: from 1992 to 1997, 127 patients with locally advanced head and neck cancer (stage III-IV) were randomized. Sixty-six patients (group a), 42 male and 24 female, with a median age of 48 years (range 40-72) received during radiotherapy two courses (1.-6. week) of chemotherapy with carbo-platin (300 mg/m{sup 2} day 1) and etoposide (60 mg/m{sup 2} days 1 to 3). Sixty-one patients (group b), 40 male and 21 female, with a median age of 51 years (range 42-69) received two cycles of chemotherapy with 5 FU (750 mg/m{sup 2} days 1 to 5) and MIT C ( 10 mg/m{sup 2} day 1). The median dose of radiotherapy was 60 Gy (range 55-66 Gy) 180 cGy /d 5w. Results: the actuarial five-year survival rate(Kaplan-Meier) was 38 % for group a (CBDCA+etoposide+RT) and 25 % for group b (5FU+MIT C+RT). The difference was statistically significant (p = 0.036). Toxicity group a: mucositis G III in 41 patients and G IV in 16; dysphagia G III in 46 patients and IV in 5; leukopenia in 24 patients; 28 patients required nutritional therapy. Toxicity group b: mucositis G III in 38 patients and G IV in 17; dysphagia G III in 48 patients and G IV in 3; leukopenia in 23 patients; 25 patients needed nutritional therapy. Conclusions: the data of the actuarial survival five-year rate suggest that concomitant chemotherapy in group a (CBDCA+etoposide+RT) is better than the concomitant chemotherapy in group b (5FU+MIT C+RT).

Survivors of head and neck squamous cell carcinoma (HNSCC) face excess mortality from multiple causes. We used the population-based Surveillance, Epidemiology, and End Results (SEER) cancer registry data to evaluate the causes of death in patients with nonmetastatic HNSCC diagnosed between 1992 and 2005 who survived at least 3 years from diagnosis (long-term survivors). We used competing-risks proportional hazards regression to estimate probabilities of death from causes: HNSCC, second primary malignancy (SPM) excluding HNSCC, cardiovascular disease, and other causes. We identified 35,958 three-year survivors of HNSCC with a median age at diagnosis of 60 years (range = 18-100 years) and a median follow-up of 7.7 years (range = 3-18 years). There were 13,120 deaths during the study period. Death from any cause at 5 and 10 years was 15.4% (95% confidence interval [CI] = 15.0%-15.8%) and 41.0% (95% CI = 40.4%-41.6%), respectively. There were 3852 HNSCC deaths including both primary and subsequent head and neck tumors. The risk of death from HNSCC was greater in patients with nasopharynx or hypopharynx cancer and in patients with locally advanced disease. SPM was the leading cause of non-HNSCC death, and the most common sites of SPM death were lung (53%), esophagus (10%), and colorectal (5%) cancer. Many long-term HNSCC survivors die from cancers other than HNSCC and from noncancer causes. Routine follow-up care for HNSCC survivors should expand beyond surveillance for recurrent and new head and neck cancers. © 2014 American Cancer Society.

The aim of this study was to investigate whether there is an association between text neck and neck pain in young adults. Observational cross-sectional study with 150 18-21-year-old young adults from a public high school in the state of Rio de Janeiro was performed. In the self-report questionnaire, the participants answered questions on sociodemographic factors, anthropometric factors, time spent texting or playing on a mobile phone, visual impairments, and concern with the body posture. The neck posture was assessed by participants' self-perception and physiotherapists' judgment during a mobile phone texting message task. The Young Spine Questionnaire was used to evaluate the neck pain. Four multivariate logistic regression models were fitted to investigate the association between neck posture during mobile phone texting and neck pain, considering potential confounding factors. There is no association between neck posture, assessed by self-perception, and neck pain (OR = 1.66, p = 0.29), nor between neck posture, assessed by physiotherapists' judgment, and neck pain (OR = 1.23, p = 0.61). There was also no association between neck posture, assessed by self-perception, and frequency of neck pain (OR = 2.19, p = 0.09), nor between neck posture, assessed by physiotherapists' judgment, and frequency of neck pain (OR = 1.17, p = 0.68). This study did not show an association between text neck and neck pain in 18-21-year-old young adults. The findings challenge the belief that neck posture during mobile phone texting is associated to the growing prevalence of neck pain.

Full Text Available Second primary malignancy (SPM is the major long-term cause of patient mortality with head and neck squamous cell carcinoma (HNSCC. As the incidence of high-risk human papillomavirus (HPV-related HNSCC is increasing globally, we analyzed the patterns of SPM occurrence, the effect of the index tumor site along with attributes to HPV, and the effect of SPM on survival in South Korean patients with head and neck cancer (HNC. Data were retrieved from the Korea Central Cancer Registry, a nationwide population-based cancer registry, from 1993 to 2010. Standardized incidence ratios were analyzed and compared between index tumor sites, particularly oropharyngeal vs. non-oropharyngeal sites. After adjustment for competing risks, 3- and 5-year SPM rates were calculated using the cumulative incidence function. The effects of SPM occurrence on overall survival (OS were then analyzed. SPM rates were significantly lower for HPV-attributable oropharyngeal sites than for non-oropharyngeal sites, such as the larynx and hypopharynx (p<0.001. SPM rates were also lower for oral cavity first primary sites than for non-oropharyngeal first primary sites (p<0.001. SPMs typically occurred in the esophagus, lungs and the head and neck. Uterine cervical cancers occurred significantly more frequently after index oropharyngeal cancer in women. The 5-year and 10-year OS rates were 57.8 and 45.7% in all HNC patients, respectively. The OS after SPM occurrence was poor (5-year, 31.8%; 10-year, 20.8% compared to after index HNC occurrence (5-year, 68.4%; 10-year, 41.2%. SPM occurrence in the esophagus and lung/bronchus showed a worse OS than SPM localized to the head and neck. South Korean HNC patient, the first primary cancer site affected SPM risk and distribution. The 5- and 10-year OS rates deteriorated after SPM occurrence, particularly in the esophagus and lungs. Further optimization of follow-up strategies for effective surveillance of SPM, particularly in the esophagus

Full Text Available The association of education, tobacco smoking, alcohol consumption, and interleukin-2 (IL-2 +114 and -384 and -6 (IL-6 -174 DNA polymorphisms with head and neck squamous cell carcinoma (HNSCC was investigated in a cohort study of 445 subjects. IL-2 and IL-6 genotypes were determined by real-time PCR. Cox regression was used to estimate hazard ratios (HR and 95% confidence intervals (95%CI of disease-specific survival according to anatomical sites of the head and neck. Mean age was 56 years and most patients were males (87.6%. Subjects with 5 or more years of schooling had better survival in larynx cancer. Smoking had no effect on HNSCC survival, but alcohol consumption had a statistically significant effect on larynx cancer. IL-2 gene +114 G/T (HR = 0.52; 95%CI = 0.15-1.81 and T/T (HR = 0.22; 95%CI = 0.02-3.19 genotypes were associated with better survival in hypopharynx cancer. IL-2 +114 G/T was a predictor of poor survival in oral cavity/oropharynx cancer and larynx cancer (HR = 1.32; 95%CI = 0.61-2.85. IL-2 -384 G/T was associated with better survival in oral cavity/oropharynx cancer (HR = 0.80; 95%CI = 0.45-1.42 and hypopharynx cancer (HR = 0.68; 95%CI = 0.21-2.20, but an inverse relationship was observed for larynx cancer. IL-6 -174 G/C was associated with better survival in hypopharynx cancer (HR = 0.68; 95%CI = 0.26-1.78 and larynx cancer (HR = 0.93; 95%CI = 0.42-2.07, and C/C reduced mortality in larynx cancer. In general, our results are similar to previous reports on the value of education, smoking, alcohol consumption, and IL-2 and IL-6 genetic polymorphisms for the prognosis of HNSCC, but the risks due to these variables are small and estimates imprecise.

Patients with head and neck (H&N) cancer are commonly treated with surgery and/or radiotherapy, which can increase the risk of oral infection, dental caries, and periodontal disease. The present study investigated dental care consumption and costs in patient with H&N cancer before and after the cancer diagnosis. Data from Swedish regional and national registers were used to follow up dental care utilization and dental procedure costs. The analysis included 2,754 patients who had been diagnosed with H&N cancer (exposed cohort) in Stockholm County, Sweden, during 2000-2012 and 13,036 matched persons without cancer (unexposed cohort). The exposed cohort was sub-grouped into irradiated and non-irradiated patients for analysis. The exposed cohort underwent a moderately higher number of dental procedures per year than the unexposed cohort in both the year of the cancer diagnosis and the year after cancer diagnosis; in addition, these numbers were higher in the irradiated than in the non-irradiated subgroup of the exposed cohort. Dental care consumption and costs in the exposed cohort declined over time but remained at a slightly higher level than in the unexposed cohort over the long term (more than two years). Examinations and preventive procedures accounted for most of the higher consumption in the short term (2 years) and at the longer term follow-up. Swedish national insurance subsidized costs for dental treatment, which were highest in the irradiated subgroup and lowest in the unexposed cohort. Direct costs to the patient, however, were similar among the groups. Swedish national health insurance protects patients with H&N cancer from high dental expenditures. Further studies on the cost-effectiveness of preventive dental care for patients are needed.

Full Text Available Eugenia Allegra, Serena TrapassoOtolaryngology – Head and Neck Surgery, University Magna Graecia of Catanzaro, Catanzaro, ItalyAbstract: Cancer stem cells (CSCs, also called "cells that start the tumor," represent in themselves one of the most topical and controversial issues in the field of cancer research. Tumor stem cells are able to self-propagate in vitro (self-renewal, giving rise both to other tumor stem cells and most advanced cells in the line of differentiation (asymmetric division. A final characteristic is tumorigenicity, a fundamental property, which outlines the tumor stem cell as the only cell able to initiate the formation of a tumor when implanted in immune-deficient mice. The hypothesis of a hierarchical organization of tumor cells dates back more than 40 years, but only in 1997, thanks to the work of John Dick and Dominique Bonnet, was there the formal proof of such an organization in acute myeloid leukemia. Following this, many other research groups were able to isolate CSCs, by appropriate selection markers, in various malignancies, such as breast, brain, colon, pancreas, and liver cancers and in melanoma. To date, however, it is not possible to isolate stem cells from all types of neoplasia, particularly in solid tumors. From a therapeutic point of view, the concept of tumor stem cells implies a complete revision of conventional antineoplastic treatment. Conventional cytotoxic agents are designed to target actively proliferating cells. In the majority of cases, this is not sufficient to eliminate the CSCs, which thanks to their reduced proliferative activity and/or the presence of proteins capable of extruding chemotherapeutics from the cell are not targeted. Therefore, the theory of cancer stem cells can pose new paradigms in terms of cancer treatment. Potential approaches, even in the very early experimental stages, relate to the selective inhibition of pathways connected with self-renewal, or more specifically based on

Full Text Available Head and neck cancers are the most common cancers in developing countries, especially in Southeast Asia. Head and neck cancers are more common in males compared to females. This is mainly attributed to tobacco, areca nut, alcohol, etc. Oral cancers are most common amongst all head and neck squamous cell cancers (HNSCC. HNSCC in the developing world differ from those in the Western world in terms of age, site of disease, etiology, and molecular biology. Poverty, illiteracy, advanced stage at presentation, lack of access to health care, and poor treatment infrastructure pose a major challenge in management of these cancers. The annual GDP (gross domestic product spent on health care is very low in developing countries compared to the developed countries. Cancer treatment leads to a significant financial burden on the cancer patients and their families. Several health programs have been implemented to curb this rising burden of disease. The main aims of these health programs are to increase awareness among people regarding tobacco and to improve access to health care facilities, early diagnosis, treatment, and palliative care.

The effects of hyperfractionation radiation therapy, such as the failure pattern and survival, on the treatment results in advanced stage head and neck cancer were studied. Between September 1990 and October 1998, 24 patients with advanced stage (III, IV) head and neck cancers, were treated using hyperfractionation radiation therapy in the Department at Radiation Oncology at the Keimyung University Dongsan Medical Center. The male to female ratio was 7 ; 1, and the age range from 38 to 71 years with the median of 56 years. With regard to the TNM stage, 11 patients were stage III and 13 were stage IV. The sites of primary cancer were the nasopharynx in six, the hypopharynx in 6, the larynx in five, the oropharynx in three, the maxillary sinus in three, and the oral cavity in one patient. The radiotherapy was delivered by 6 MV X-ray, with a fraction size of 1.2 Gy at two fractions a day, with at least 6 hours inter-fractional interval. The mean total radiation doses was 72 Gy, (ranging from 64.4 to 76.8 Gy). Fallow-up periods ranged between 3 and 136 months, with the median of 52 months. The overall survival rates at 3 and 5 years in all patients were 66.7% and 52.4%. The disease-free survival rates at 3 and 5 years (3YDFS, 5YDFS) in all patients Were 66.7% and 47.6%. The 3YDFS and 5YDFS in stage III patients were 81.8% and 63.6%, and those in stage IV patients were 53.8% and 32.3%. Ten patients were alive with no local nor distant failures at the time of analyses. Six patients (25%) died due to distant metastasis and 12.5% died due to local failure. Distant metastasis was the major cause of failure, but 2 patients died due to unknown failures and 3 of other diseases. The distant metastasis sites were the lung (3 patients), the bone (1 patient), and the liver (2 patients). One patient died of second esophageal cancer. There were no severe late complications, with the exception of 1 osteoradionecrosis of the mandible 58 months after treatment. Although this study was

The aim of this study is to assign dose-response relationship for subclinical neck metastases of squamous cell head and neck cancer based on extensive survey of 24 data sets collected from the literature. Neck relapse rates (NRR) without and after elective (ENI) or preoperative irradiation were estimated for each site and stage of primary tumor and the reduction in neck relapse rate was calculated. An average NRR without ENI was 22% (12-35% ) and only 2.5% (0-1 0%) after the ENI with total dose of 46- 50 Gy which gives high reduction rate in the risk of neck recurrences being on the average 89% and 42% (0-46%) after preoperative irradiation using 22-30 Gy. Dose response curve for elective and preoperative irradiation have shown that 50 Gy in 2 Gy fraction reduces the incidence of neck relapses in the NO patients by more than 90% and only by less than 50% after total doses lower than 30 Gy. No correlation between the risk of neck metastases without ENI and the reduction in neck relapses after ENI was found. (authors)

The 18 F-fluorodeoxyglucose positron emission tomography-computed tomography ( 18 F-FDG-PET/CT) procedure is a cornerstone in the diagnostics of head and neck cancers. Several years ago PET-magnetic resonance imaging (PET/MRI) also became available as an alternative hybrid multimodal imaging method. Does PET/MRI have advantages over PET/CT in the diagnostics of head and neck cancers ?The diagnostic accuracy of the standard imaging methods CT, MRI and PET/CT is depicted according to currently available meta-analyses and studies concerning the use of PET/MRI for these indications are summarized. In all studies published up to now PET/MRI did not show superiority regarding the diagnostic accuracy in head and neck cancers; however, there is some evidence that in the future PET/MRI can contribute to tumor characterization and possibly be used to predict tumor response to therapy with the use of multiparametric imaging. Currently, 18 F-FDG-PET/CT is not outperformed by PET/MRI in the diagnostics of head and neck cancers. The additive value of PET/MRI due to the use of multiparametric imaging needs to be investigated in future research. (orig.) [de

Full Text Available INTRODUCTION Mortality and morbidity associated with head and neck cancers have decreased to a great extent in many developed countries of the world due to early diagnosis and treatment with advances in surgical techniques and better availability of radiotherapist and oncologists. But the situation in developing countries like India is quite different. AIMS AND OBJECTIVES This study was conducted amongst the patients attending the Otolaryngology department of a teaching hospital in Kolkata to find the incidence of various types and sites of head and neck cancer, to assess time delay from the date of onset of symptom to the final disease confirmation in relation to patients’ demographic profile, to assess time delay in histopathological diagnosis after reaching a tertiary care setup and also to correlate tobacco consumption and alcohol intake as risk factors for head and neck cancer and to note the reasons for late presentation, as described by the patient. MATERIALS AND METHODS The descriptive study was conducted at a tertiary level teaching hospital, in the Department of Otorhinolaryngology for a period from August 2013 to August 2015 with a study population of 133.  OBSERVATIONS  An average time lag from the onset of symptom to final diagnosis as malignancy was found to be 6 months to one year in nearly 72% of cases. Most of the patients were uneducated males of more than 50 years of age, hailing from rural areas. Cancer larynx was found to be the commonest of all head and neck cancers (31.6%. More than 65% of the patients were addicted to tobacco chewing or smoking or consumption of alcohol.  DISCUSSION  Poverty, lack of education, poor communication, lack of health care infrastructure in rural areas, community awareness about various risk factors, lack of effective health policy to achieve early diagnosis of head neck cancer were common factors related to delay in diagnosis.  CONCLUSION  Tobacco use and alcohol intake are the

Current and future state of chemoradiotherapy for head and neck cancer

Radiation therapy was the conventional treatment for locally advanced, nonresectable head and neck cancer. However, therapeutic results were poor with this treatment modality, and chemoradiotherapy has been used in an effort to improve therapeutic results. Improved local-regional control and disease-free or overall survival have been shown in several randomized trials using a concurrent or alternative approach. Induction chemotherapy (neoadjuvant chemotherapy), however, has not been shown to improve local-regional control or survival. Induction chemotherapy followed by definitive radiotherapy may be useful in the selection of patients who are likely to benefit from non-surgical organ preservation treatment schemes. Further clinical trials are needed to clarify the most suitable combination of chemotherapy and radiation. Intraarterial chemotherapy combined with radiation therapy for head and neck cancer has been attempted for many years. However, the indications, clinical significance, and selection of suitable anti-cancer drugs remain unclarified. The modern superselective intraarterial approach should be re-evaluated. Many head and neck cancers have been found to overexpress the receptor to epidermal growth factor (EGFR). Antibodies such as IMC-C225 that specifically target EGF receptors with radiotherapy and/or chemotherapy may prove to be valuable contributors to the treatment of advanced head and neck cancer.

Full Text Available Background : The spectrum of head and neck tumors in children continues to be the cause of diverse, diagnostically challenging issues. Aims : To demonstrate and compare the unique clinicopathological features in our study population and their correlations with the final histopathological diagnosis. Methods : Fifty-three children with head and neck cancer were examined thoroughly at the Otorhinolaryngology department in a tertiary care teaching hospital followed by histopathological studies. Results : Lymphomas were the most common malignant lesions seen followed by rhabdomyosarcomas, nasopharyngeal carcinomas, and others like thyroid carcinomas and eosinophilic granulomas. In the neck, the commonest cause of primary malignant disease was lymphoma; however, the most frequent lesion was reactive lymphadenitis. In the sinonasal region, the commonest malignancy was rhabdomyosarcoma, which often had extension to the orbit and the face. Recurrent epistaxis was found universally in the malignant cases of this region. In the facial region, disfiguring swelling with proptosis was mainly caused by rhabdomyosarcoma. The only case of tonsillar malignancy was due to non-Hodgkin lymphoma. The duration of disease was less than 1 year. Conclusion : The most common manifestation of the malignant lesions in the pediatric age group was with a history of an enlarging, painless neck swelling. Still, an insignificant lump in the neck or recurrent bleeding from nose may be the manifestation of an underlying cancer.

Radiation therapy in combination with surgery has an important role in the therapy of the head and neck cancer. We conducted a prospective study for patients with head and neck cancer treated with surgery and radiation to evaluate the effect of therapies on the thyroid gland, and to identify the factors that might influence the development of hypothyroidism. From September 1986 through December 1994, 71 patients with head and cancer treated with surgery and radiation were included in this prospective study. Patients' age ranged from 32 to 73 years with a median age of 58 years. There were 12 women and 59 men. Total laryngectomy with neck dissection was carried out in 45 patients and neck dissection alone in 26 patients. All patients were serially monitored for thyroid function before and after radiation therapy. Radiation dose to the thyroid gland ranged from 40.6Gy to 60Gy with a median dose of 50Gy. The follow-up duration was 3 to 80 months. The overall incidence of hypothyroidism was 56.3% (40/71); 7 out of 71 patients (9.9%) developed clinical hypothyroidism and 33 patients (46.4%) developed subclinical hypothyroidism. No thyroid nodules, thyroid cancers, or hyperthyroidism was detected. The risk factor that significantly influenced the incidence of hypothyroidism was a combination of surgery (total laryngectomy with neck dissection) and radiation therapy (P=0.0000). Four of 26 patients (15.4%) with neck dissection alone developed hypothyroidism while 36 of 45 patients (80%) with laryngectomy and neck dissection developed hypothyroidism. The hypothyroidism following surgery and radiation therapy was a relatively common complication. The factor that significantly influenced the incidence of hypothyroidism was combination of surgery and radiation therapy. Evaluation of thyroid function before and after radiation therapy with periodic thyroid function tests is recommended for an early detection of hypothyroidism and thyroid hormone replacement therapy is

To assess the impact of intensity modulated radiotherapy (IMRT) versus conventional radiation on late xerostomia and Quality of Life aspects in head and neck cancer patients. Questionnaires on xerostomia in rest and during meals were sent to all patients treated between January 1999 and December 2003 with a T1-4, N0-2 M0 head and neck cancer, with parotid gland sparing IMRT or conventional bilateral neck irradiation to a dose of at least 60 Gy, who were progression free and had no disseminated disease (n = 192). Overall response was 85% (n = 163); 97% in the IMRT group (n = 75) and 77% in the control group (n = 88) the median follow-up was 2.6 years. The prevalence of complaints was compared between the two groups, correcting for all relevant factors at multivariate ordinal regression analysis. Patients treated with IMRT reported significantly less difficulty transporting and swallowing their food and needed less water for a dry mouth during day, night and meals. They also experienced fewer problems with speech and eating in public. Laryngeal cancer patients in general had fewer complaints than oropharynx cancer patients but both groups benefited from IMRT. Within the IMRT group the xerostomia scores were better for those patients with a mean parotid dose to the 'spared' parotid below 26 Gy. Parotid gland sparing IMRT for head and neck cancer patients improves xerostomia related quality of life compared to conventional radiation both in rest and during meals. Laryngeal cancer patients had fewer complaints but benefited equally compared to oropharyngeal cancer patients from IMRT

To improve the local control rate in radiotherapy for hand and neck cancer, several prospected twice-a-day fractionated radiotherapy (TDRF) were conducted in Tokyo Women`s Medical College. T2 glottic cancer was irradiated with 1.5 Gy/fraction, 2 fraction/day to a total dose of 72 Gy. Five cumulative local control rate was 88.2%. Locally advanced head and neck cancer was treated with TDFR and systemic chemotherapy. Response rate was 100%. Palliative radiotherapy with TDFR was done to relive from the pain and other symptoms for advanced and recurrent cases. Nine cases of 11 were relieved from the symptoms. These results was suggested the TDFR was useful to improve the local control rate. (author)

Head and neck cancer constitutes a substantial portion of the burden of disease in South Asia, and there is an undersupply of surgical capacity in this region. The purpose of this study was to estimate the economic welfare losses due to head and neck cancer in India, Pakistan, and Bangladesh in 2010. We used publicly available estimates of head and neck cancer morbidity and mortality along with a concept termed the value of a statistical life to estimate economic welfare losses in the aforementioned countries in 2010. Economic losses because of head and neck cancer in India, Pakistan, and Bangladesh totaled $16.9 billion (2010 US dollars [USD]), equivalent to 0.26% of the region's economic output. Bangladesh, the poorest country, experienced the greatest proportional losses. The economic consequences of head and neck cancer in South Asia are significant, and building surgical capacity is essential to begin to address this burden. © 2016 Wiley Periodicals, Inc.

The management of patients with recurrent neck cancer invading the carotid artery is controversial. The purpose of this study was to evaluate overall survival rate, primary patency of vascular reconstructions, and quality-adjusted life-years (QALYs) after en bloc resection of the carotid artery and tumor with in-line polytetrafluoroethylene (PTFE) carotid grafting, followed by radiotherapy. From 2000 to 2014, 31 consecutive patients with recurrent neck cancer invading the carotid artery underwent en bloc resection and simultaneous carotid artery reconstruction with a PTFE graft, which was associated in 18 cases with a myocutaneous flap. The primary tumor was a squamous cell carcinoma of the larynx in 17 patients and of the hypopharynx in 7, an undifferentiated carcinoma of unknown origin in 4, and an anaplastic carcinoma of the thyroid in 3. All of the patients underwent postoperative radiotherapy (50-70 Gy), and 10 of them also underwent chemotherapy (doxorubicin and cisplatin). None of the patients died or sustained a stroke during the first 30 days after the index procedure. Postoperative morbidity consisted of 6 transitory dysphagias, 3 vocal cord palsies, 2 wound dehiscences, 1 transitory mandibular claudication, and 1 partial myocutaneous flap necrosis. No graft infection occurred during follow-up. Fifteen patients (48%) died from metastatic cancer during a mean follow-up of 45.4 months (range, 8-175 months). None of the patients showed evidence of local recurrence, stroke, or thrombosis of the carotid reconstruction. The 5-year survival rate was 49 ± 10%. The overall number of QALYs was 3.12 (95% confidence interval, 1.87-4.37) with a significant difference between patients without metastasis at the time of redo surgery (n = 26; QALYs, 3.74) and those with metastasis (n = 5; QALYs, 0.56; P = .005). QALYs were also significantly improved in patients with cancer of the larynx (n = 17; QALYs, 4.69) compared to patients presenting with other types of

Different site specificity of second primary cancer following treatment for early stage squamous cell carcinoma of the head and neck was found in the analysis of post-treatment long-term follow up cases. The highest risk of second primary cancer was observed in the oro-hypo-pharynx cancer groups, and the lowest risks were observed in the epi-pharynx cancer and maxillary sinus cancer groups. Squamous cell carcinoma in the irradiated head and neck region with long latency periods could be included in the radiation induced cancer from comparison with post-irradiation cases for malignant lymphoma, benign diseases as well as breast cancers.

Chronic exposure to heavy metals has long been recognized as being capable to increase head and neck cancer incidence among exposed human populations. Head and neck cancer is a significant public health issue in Tunisia. The aim of the present study was to evaluate the concentrations of As, Cd, Cr and Ni in healthy and tumor tissues of head and neck cancer patients. Metal concentrations were determined in tumor and healthy tissues of 101 head and neck cancer patients, using Atomic Absorption Spectrometry. The As, Cd, Cr, and Ni levels in tumor tissues were 3.4, 2.5, 1.3 and 1.5 times higher than those of healthy tissues (p < 0.05), respectively. Tumor tissue metal levels were higher in men than in women. As and Cd levels in tumor and healthy tissue samples of patients smokers are significantly higher than those of non-smokers (p < 0.05). A strong effect of cumulative smoking as expressed in the number of pack per year, and tumor tissue Cd levels were positively associated with three groups of age (< 40, 51–60 and > 60 years) in both never-smokers and ever-smokers (< 20 and ≥ 20 pack per year). Healthy tissue Cd levels were negatively associated with age in those three groups of smokers. The highest Cd and Cr concentrations among both workers and non-workers were observed in tumor tissues. The Cd and Cr in tissues of farmers, bricklayers and painters were all significantly higher among the workers as compared with the non-workers group. Tissue metal levels have increased due to smoking and occupational exposure. Heavy metal exposure via tobacco smoking and occupational exposures may increase the risk of head and neck in the Tunisian population. - Highlights: ► Heavy metal levels in tumor tissues were higher than those in healthy tissues. ► Tumor tissue Cd levels were positively associated with age in smokers. ► Tumor tissue metal levels were higher in men than in women. ► The highest Cd and Cr concentrations among workers were observed in tumor tissues

The care of head and neck squamous cell carcinoma has greatly evolved over the past 30 years. From single modality to a multidisciplinary care, there has also been a concurrent increase in treatment intensity, resulting, at many times, in more zealous regimens that patients must endure. In this article, we apply Porter's value model as a framework to balance survival, toxicities, cost, and trade-offs from a patient's perspective in head and neck cancer. This model defines value as the health outcome per dollar achieved. Domains and outcomes that are important to patients, including not only survival or short-term quality of life, but also functional outcomes, recovery, sustainability of recovery, and the lasting consequences of therapy are included in this framework. Other outcomes that are seldom measured in head and neck cancer, such as work disability and financial toxicities, are also included and further discussed. Within this value model and based on evidence, we further discuss de-escalation of care, intensity-modulated radiation therapy, newer surgical methods, and enhancements in the process of care as potential approaches to add value for patients. Finally, we argue that knowing the patient's preferences is essential in the value discussion, as the attribute that will ultimately provide the most value to the individual patient with head and neck cancer.

Reactive cervical lymphadenopathy is common in children and may demonstrate increased 18 F-fluoro-deoxyglucose ( 18 F-FDG) uptake on positron emission tomography/computed tomography (PET/CT). We sought to evaluate the frequency and significance of 18 F-FDG uptake by neck lymph nodes in children with no history of head and neck cancer. The charts of 244 patients (114 female, mean age: 10.4 years) with a variety of tumors such as lymphoma and post-transplant lymphoproliferative diseases (PTLD), but no head and neck cancers, who had undergone 18 F-FDG PET/CT were reviewed retrospectively. Using the maximum standardized uptake value (SUVmax), increased 18 F-FDG uptake by neck lymph nodes was recorded and compared with the final diagnosis based on follow-up studies or biopsy results. Neck lymph node uptake was identified in 70/244 (28.6%) of the patients. In 38 patients, the lymph nodes were benign. In eight patients, the lymph nodes were malignant (seven PTLD and one lymphoma). In 24 patients, we were not able to confirm the final diagnosis. Seven out of the eight malignant lymph nodes were positive for PTLD. The mean SUVmax was significantly higher in malignant lesions (4.2) compared with benign lesions (2.1) (P = 0.00049). 18 F-FDG uptake in neck lymph nodes is common in children and is frequently due to reactive lymph nodes, especially when the SUVmax is cervical lymph nodes is higher in PTLD patients compared with other groups.

The authors discuss the case of radiation-induced skin cancer of the neck in a 76-year-old woman who had undergone irradiation of tubercular lymphadenitis of the cervix while in her low teens. Some fifty years later, a squamous cell carcinoma developed in the irradiated region and in due course deeply invaded the sternocleidomastoidous muscle. Thus, a radical neck dissection was performed and the tumor and the lymph tissue removed en bloc, after which reconstruction was accomplished by using a latissimus dorsi musculocutaneous flap. With regard to the lessons learned from treating this case, three points are considered important and are listed below. When treating radiation-induced skin cancer patients, the head and neck regions should be examined in detail for the presence of other tumors. The excision of the skin surrounding the tumor should be as wide as possible, so as to remove skin that may have been also over-subjected to irradiation. The remaining skin surrounding the defect left by the excision is atrophic and thin. (author)

Leiomyosarcoma is a rare neoplasm of the head and neck. The purpose of this study was to present our single-institution case series of head and neck leiomyosarcoma and a review of cases in the National Cancer Data Base (NCDB). Patients with head and neck leiomyosarcoma at the University of Pennsylvania and in the NCDB were identified. Demographic characteristics, tumor factors, treatment paradigms, and outcomes were evaluated for prognostic significance. Nine patients with head and neck leiomyosarcoma from the institution were identified; a majority had high-grade disease and cutaneous leiomyosarcoma, with a 5-year survival rate of 50%. Two hundred fifty-nine patients with leiomyosarcoma were found in the NCDB; macroscopic positive margins and high-grade disease were associated with poor prognosis (P < .01), and positive surgical margins were related to adjuvant radiation (P < .001). Head and neck leiomyosarcoma presents at a high grade and is preferentially treated with surgery. Several demographic and tumor-specific factors are associated with outcomes and prognosis. © 2017 Wiley Periodicals, Inc.

The limitation of concurrent chemo-radiotherapy (CCRT) in head and neck cancer (HNC) as the primary treatment is described based on recent findings. Limits in the application/indication involve factors of age, performance status (PS) and renal function. The first is that, as deaths in >71 years old patients are derived from other causes (41%) than HNC, CCRT is only useful for younger population; the second, patients with PS 0-1 or Karnofsky performance score >60-70 can be indicated; and third, contraindicated are those with creatinine clearance (CCr) <60 mL/min as the key drug cisplatin in CCRT has a high renal toxicity. It should be recognized that completion rates of chemotherapy and RT are as low as 66-85% and 84-92%, respectively, in CCRT. CCRT has such limiting adverse events as mucitis, dry mouth, dysohagia, weight loss, neutropenia, sepsis, etc., which are most important in CCRT application. CCRT is recommended for the primary cancers of larynx and hypopharynx because they are significantly better conserved than middle pharyngeal, oral and upper jaw cancers. Evidence of CCRT is poor for cancers in paranasal sinuses. Planned neck dissection (PND) is for the cervical metastatic lymph nodes and conducted 6-12 weeks after CCRT regardless to its outcome. In fluorodeoxyglucose-positron emission tomography (FDG-PET) negative cases, PND can be omitted. Necessity of PND is possibly inversely proportional to CCRT intensity performed. For control of remote metastasis, CCRT has obvious limits and inductive chemotherapy before it is currently considered. Salvage surgery post CCRT does not always yield a relief because of complication. Patients with advanced laryngeal cancer can be selected either to surgery or CCRT depending on results of the inductive chemotherapy. To predict the sensitivity to CCRT, some biomarkers like HPV, EGFR and VEGF have been suggested to be useful by retrospective studies. Understanding the limitation is as important as knowing the usefulness in

Overall response was 85% (n = 163); 97% in the IMRT group (n = 75) and 77% in the control group (n = 88) the median follow-up was 2.6 years. The prevalence of complaints was compared between the two groups, correcting for all relevant factors at multivariate ordinal regression analysis. Results Patients treated with IMRT reported significantly less difficulty transporting and swallowing their food and needed less water for a dry mouth during day, night and meals. They also experienced fewer problems with speech and eating in public. Laryngeal cancer patients in general had fewer complaints than oropharynx cancer patients but both groups benefited from IMRT. Within the IMRT group the xerostomia scores were better for those patients with a mean parotid dose to the "spared" parotid below 26 Gy. Conclusion Parotid gland sparing IMRT for head and neck cancer patients improves xerostomia related quality of life compared to conventional radiation both in rest and during meals.

Recently, the use of chemoradiotherapy for preserving organs in the treatment of head and neck cancer is increasing. However, there is controversy about advanced neck node management in post-chemoradiation cases. We retrospectively analyzed our 119 cases of chemoradiotherapy for oropharyngeal and hypopharyngeal cancer to examine the effectiveness and indications of planned neck dissection. Regional control rate and survival rate were superior in the neck dissection group. If the cases did not achieve complete response (CR) in imaging, planned neck dissection improved the regional control rate significantly. We should perform planned neck dissection immediately rather than 'wait and see' for this persistent disease. However, in the cases achieving radiological CR, it is possible to omit planned neck dissection because of the high salvage rate of neck disease. However, in these cases, careful observation is essential. We clarified that the presence of pathologically positive lymph node is a prognostic factor. For evaluating persistent disease of cervical lymph nodes, positron emission tomography (PET)-CT was the most accurate method of imaging. (author)

Thirty-five FA patients were diagnosed with HNSCC at a mean age of 32 years. The most common site of primary cancer was the oral cavity (26 of 35, 74%). Thirty patients underwent surgical resection of the cancer. Sixteen patients received radiation therapy with an average radiation dose of 5,050 cGy. The most common toxicities were high-grade mucositis (9 of 16, 56%), hematologic abnormalities (8 of 16, 50%), and dysphagia (8 of 16, 50%). Three patients received conventional chemotherapy and had significant complications, whereas three patients who received targeted chemotherapy with cetuximab had fewer toxicities. The 5-year overall survival rate was 39%, with a cause-specific survival rate of 47%. Fanconi anemia patients have a high risk of developing aggressive HNSCC at an early age. Fanconi anemia patients can tolerate complex ablative and reconstructive surgeries, but careful postoperative care is required to reduce morbidity. The treatment of FA-associated HNSCC is difficult secondary to the poor tolerance of radiation and chemotherapy. However, radiation should be used for high-risk cancers due to the poor survival in these patients. 4. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

Postoperative radiation for advanced head and neck cancers

International Nuclear Information System (INIS)

Purpose: To discuss both general and specific indications for radiation following surgery for patients with cancers of the head and neck. Patients with advanced cancers of the head and neck are often not suitable candidates for treatment with definitive radiation, and are treated with surgery. Frequently these patients fail by recurring in either the primary sites or in the necks. Adjuvant radiation is therefore often a critical component in the management of these patients. While radiation can be done either prior to or after surgery, most centers prefer the postoperative setting. This refresher course will review general concepts of postoperative irradiation for the patient with head and neck cancer and apply these concepts to specific situations. The course will begin with a broad review of the indications for postoperative irradiation as not all patients undergoing surgery for cancers of the head and neck require additional treatment. We will also review the concept of using postoperative radiation to allow for more conservative surgery with preservation of function. The second portion of the course will focus on general techniques of postoperative irradiation. We will review concepts of patient setup and treatment portal design and describe how specific techniques are practiced at MDACC. Controversial topics, including field matching, total dose and fractionation, and the timing of postoperative radiation will be discussed. The final section of the course will review the results of postoperative irradiation as applied to the head and neck in general as well as to specific subsites. In addition to results for the common scenarios of squamous cell carcinomas of the oral cavity, pharynx and larynx, we will review results of postoperative irradiation for skin cancers of the head and neck, paranasal sinuses, and salivary glands

The illnesses of celebrity patients always receive more attention from the general public than those of ordinary patients. With regard to cancer, this fact has helped to spread information about the four major malignancies: breast cancer, prostatic cancer, lung cancer and colorectal cancer. Head and neck cancer, on the other hand, is still not well recognised by the lay public, although the risk factors are similar to those of lung cancer. It was the objective of this analysis to identify cases of celebrity patients, the description of which could help to increase awareness of head and neck cancer, its symptoms and risk factors. The Internet and medical literature databases were searched for celebrity patients who had suffered from head and neck cancer. The search revealed numerous famous head and neck cancer patients. However, only seven cases were documented well in the medical literature. Among the identified persons were one emperor, two United States presidents, a legendary composer, a world-renowned medical doctor, an outstanding athlete and an extraordinary entertainer. In spite of their exclusive position in society, these patients did not have a better prognosis compared with ordinary patients of their time. Only two of the group experienced long term survival and only one was cured. None of these influential figures used their influence to fund research or to promote knowledge about their respective diseases. The identified cases could help increase public awareness of head and neck cancer. Similar to activities in other oncologic fields, current celebrity head and neck cancer patients should be encouraged to discuss their diseases openly, which could have a positive effect on public health.

Full Text Available 18F-FDG PET plays an increasing role in diagnosis and management planning of head and neck cancer. Hybrid PET/CT has promoted the field of molecular imaging in head and neck cancer. This modality is particular relevant in the head and neck region, given the complex anatomy and variable physiologic FDG uptake patterns. The vast majority of 18F-FDG PET and PET/CT applications in head and neck cancer related to head and neck squamous cell carcinoma. Clinical applications of 18F-FDG PET and PET/CT in head and neck cancer include diagnosis of distant metastases, identification of synchronous 2nd primaries, detection of carcinoma of unknown primary and detection of residual or recurrent disease. Emerging applications are precise delineation of the tumor volume for radiation treatment planning, monitoring treatment, and providing prognostic information. The clinical role of 18F-FDG PET/CT in N0 disease is limited which is in line with findings of other imaging modalities. MRI is usually used for T staging with an intense discussion concerning the preferable imaging modality for regional lymph node staging as PET/CT, MRI, and multi-slice spiral CT are all improving rapidly. Is this review, we summarize recent literature on 18F-FDG PET and PET/CT imaging of head and neck cancer.

This paper discusses twenty patients with radiation-induced cancers of the head and neck treated in the Department of Otorhinolaryngology, the Center for Adult Diseases, Osaka, from January 1979 to December 1985. The most common site of radiation-induced cancers was the hypopharynx and cervical esophagus (70%). We found synchronous double cancers in 2 out of the 20 patients (10%). One patient had hypopharyngeal cancer and thyroid cancer, and the other had oropharyngeal cancer and thyroid cancer. All of the laryngeal cancers were in the supraglottic area. Cancer of the hypopharynx and cervical esophagus occurred more frequently in females (1:3.7 males-females ratio). Half of the patients (10/20) had received irradiation for tuberculous cervical adenitis and 8 patients had been irradiated for malignant tumors. The averaged latent period in the patients who had irradiated for benign conditions was 37.4 years, and that for malignant diseases was 16.0 years. Therefore the latent period of the former was 2.3 times as long as that of the latter. The incidence of radiation-induced cancers in all the patients who had the cancer of the hypopharynx and cervical esophagus was 9% and that of the laryngeal cancer was 0.7%. The incidence of radiation-induced cancers in the hypopharynx and cervical esophagus remarkably differed from that in the larynx. However, it was suggested that the larynx was as resistant to radiation induction as the hypopharynx. Six of the 20 patients (30%) had radiation-induced thyroid tumors. Among them, the incidence of cancers was 33%. (author)

Smell and taste disorders, sicca symptoms, can be detected in patients with head and neck cancer. The purpose of this study was to assess the utility of local liposomal application in the treatment of patients with head and neck cancers. Ninety-eight patients with head and neck cancer were included in this study. The groups were defined as: group 1 = only surgery; group 2 = surgery + adjuvant radiochemotherapy; and group 3 = primarily radiochemotherapy. All patients had finished cancer treatment and received liposomal sprays for the nose and mouth for 2 months (LipoNasal, LipoSaliva; Optima Pharmaceutical GmbH, Germany) and suffered from taste and smell disorders. We performed tests with "Sniffin' Sticks," "Taste Strips," and a xerostomia questionnaire before and after treatment. After application of liposomes, patients demonstrated a statistically significant increase in smell and taste, and reduced xerostomia. Our results demonstrate that using nonpharmaceutical liposomal sprays improve smell, taste, and symptoms of xerostomia in patients with head and neck cancer. © 2015 Wiley Periodicals, Inc.

Birkeland, Andrew C; Ludwig, Megan L; Spector, Matthew E; Brenner, J Chad

2016-01-01

Head and neck squamous cell carcinoma remains a highly morbid and fatal disease. Importantly, genomic sequencing of head and neck cancers has identified frequent mutations in tumor suppressor genes. While targeted therapeutics increasingly are being investigated in head and neck cancer, the majority of these agents are against overactive/overexpressed oncogenes. Therapy to restore lost tumor suppressor gene function remains a key and under-addressed niche in trials for head and neck cancer. Recent advances in gene editing have captured the interest of both the scientific community and the public. As our technology for gene editing and gene expression modulation improves, addressing lost tumor suppressor gene function in head and neck cancers is becoming a reality. This review will summarize new techniques, challenges to implementation, future directions, and ethical ramifications of gene therapy in head and neck cancer.

Full Text Available Abstract Background survivors of non-Hodgkin's lymphoma (NHL are well known to be at an increased risk of second malignancies. In this study, we evaluated the incidence and clinical features of head and neck cancer (HNC occurring after radiotherapy (RT for NHL. Materials and methods We investigated the clinical records of 322 patients who had received RT for early-stage NHL of the head and neck at our institute between 1952 and 2000. Results There were 4 patients with a second HNC developing in the irradiated field, consisting of 2 patients with gum cancer, 1 case with tongue cancer and 1 case with maxillary sinus cancer. The pathological diagnosis in all the 4 patients was squamous cell carcinoma (SCC. Two of the patients (one with gum cancer and one with maxillary sinus cancer died of the second HNC, while the remaining 2 patients are still living at the time of writing after therapy for the second HNC, with neither recurrence of the second tumor nor relapse of the primary tumor. The ratio of the observed to the expected number (O/E ratio of a second HNC was calculated to be 12.7 (95%CI, 4.07–35.0, and the absolute excess risk (AER per 10,000 person-years was 13.3. The median interval between the RT and the diagnosis of the second HNC was 17.0 years (range, 8.7 to 22.7 years. Conlusion The risk of HNC significantly increased after RT for early-stage NHL. These results suggest that second HNC can be regarded as one of the late complications of RT for NHL of the head and neck.

Since 1995, we have conducted intra-arterial chemotherapy for advanced head and neck cancer to improve prognosis and to preserve significant organs. Novel approaches have increased the organ preservation rate in spite of frequent distant metastasis. Cimetidine, a kind of H2-blocker, inhibits the development of E-selectin on vascular endothelial cells, and contributes to a decrease in distant metastasis and improvement in prognosis for digestive cancer. To evaluate the decrease in distant metastasis and its relation to the administration of Cimetidine when used concurrently with intra-arterial chemotherapy for advanced head and neck cancer. 153 patients treated by intra-arterial chemotherapy for stage IV head and neck cancer from May 2000 to December 2008 were divided into two groups: the Cimetidine group (114 patients) and the non-Cimetidine group (39 patients). Analysis of distant metastasis between the two groups was performed retrospectively. Intra-arterial chemotherapy was administered at 150 mg/m 2 of cisplatin (CDDP) four times per week. In the Cimetidine group, 800 mg of Cimetidine was administered for a period of more than one year prior to treatment. Fluorodeoxyglucose positron emission tomography (FDG-PET) was performed 2 months after the treatment. Pulmonary CT was performed every 6 months, and chest X-ray examination was conducted every three months. The median period of observation was 45 months for the Cimetidine group and 64 months for the non-Cimetidine group (p<0.05). Distant metastasis was detected in 10 out of the 39 cases in the non-Cimetidine group and in 6 out of the 114 cases in the Cimetidine group (p<0.05). Metastatic organs consisted of: 8 cases in lungs, 5 cases in bones, 2 cases in brain, and 1 case in retroperitoneum. The mean time of distant metastasis after treatment was 6.9 months (2-20). Combined intra-arterial chemotherapy and Cimetidine is useful for the treatment of advanced head and neck cancer due to increased loco

Surgery and/or radiotherapy have been the standard therapies for locally advanced squamous cell carcinoma of the head and neck region. Despite major improvement in these therapeutic techniques, the control rate in cases of advanced cancer remains poor. More recently, induction chemotherapy as initial treatment has been used in previously untreated squamous cell carcinoma of the head and neck. For the last 6 years at the Boston Veterans Administration (V.A.) Medical Center, initial induction chemotherapy followed by surgery and/or radiotherapy has been employed in the treatment of advanced head and neck cancer. The use of chemotherapy and radiotherapy has allowed the authors to monitor and correlate sequential response patterns produced by each modality of treatment. The authors have observed that responders to chemotherapy can be predicted to have further response to subsequent radiotherapy

Head and neck cancer is one of the most frequent malignances worldwide. Despite the site-specific multimodality therapy, up to half of the patients will develop recurrence. Treatment selection based on a multidisciplinary tumor board represents the cornerstone of head and neck cancer, as it is essential for achieving the best results, not only in terms of outcome, but also in terms of organ-function preservation and quality of life. Evidence-based international and national clinical practice guidelines for head and neck cancer not always provide answers in terms of decision-making that specialists must deal with in their daily practice. This is the first Expert Consensus on the Multidisciplinary Approach for Head and Neck Squamous Cell Carcinoma (HNSCC) elaborated by the Spanish Society for Head and Neck Cancer and based on a Delphi methodology. It offers several specific recommendations based on the available evidence and the expertise of our specialists to facilitate decision-making of all health-care specialists involved.

2016-01-01

Full Text Available We report a constellation of cervical polyneuropathies in a patient treated with concurrent bortezomib, cetuximab, and cisplatin alongside intensity modulated radiotherapy for carcinoma of the tonsil with neck metastasis. The described deficits include brachial plexopathy, cervical sensory neuropathy, and oculosympathetic, recurrent laryngeal, and phrenic nerve palsies within the ipsilateral radiation field. Radiation neuropathy involving the brachial plexus is typically associated with treatment of breast or lung cancer; however, increased awareness of this entity in the context of investigational agents with potential neuropathic effects in head and neck cancer has recently emerged. With this report, we highlight radiation neuropathy in the setting of investigational therapy for head and neck cancer, particularly since these sequelae may present years after therapy and entail significant and often irreversible morbidity.

To report a single-institutional experience using magnetic resonance imaging (MRI) guided radiation therapy for the reirradiation of recurrent and second cancers of the head and neck. Between October 2014 and August 2016, 13 consecutive patients with recurrent or new primary cancers of the head and neck that occurred in a previously irradiated field were prospectively enrolled in an institutional registry trial to investigate the feasibility and efficacy of MRI guided radiation therapy using a 0.35-T MRI scanner with a cobalt-60 radiation therapy source called the ViewRay system (ViewRay Inc., Cleveland, OH). Eligibility criteria included biopsy-proven evidence of recurrent or new primary squamous cell carcinoma of the head and neck, measurable disease, and previous radiation to >60 Gy. MRI guided reirradiation was delivered either using intensity modulated radiation therapy with conventional fractionation to a median dose of 66 Gy or stereotactic body radiation therapy (SBRT) using 7 to 8 Gy fractions on nonconsecutive days to a median dose of 40 Gy. Two patients (17%) received concurrent chemotherapy. The 1- and 2-year estimates of in-field control were 72% and 72%, respectively. A total of 227 daily MRI scans were obtained to guide reirradiation. The 2-year estimates of overall survival and progression-free survival were 53% and 59%, respectively. There were no treatment-related fatalities or hospitalizations. Complications included skin desquamation, odynophagia, otitis externa, keratitis and/or conjunctivitis, and 1 case of aspiration pneumonia. Our preliminary findings show that reirradiation with MRI guided radiation therapy results in effective disease control with relatively low morbidity for patients with recurrent and second primary cancers of the head and neck. The superior soft tissue resolution of the MRI scans that were used for planning and delivery has the potential to improve the therapeutic ratio.

Today, the cell phone is the most widespread technology globally. However, the outcome of cell-phone radiofrequency on head and neck cancer progression has not yet been explored. The chorioallantoic membrane (CAM) and human head and neck cancer cell lines, FaDu and SCC25, were used to explore the outcome of cell-phone radiofrequency on angiogenesis, cell invasion, and colony formation of head and neck cancer cells, respectively. Western blot analysis was used to investigate the impact of the cell phone on the regulation of E-cadherin and Erk1/Erk2 genes. Our data revealed that cell-phone radiofrequency promotes angiogenesis of the CAM. In addition, the cell phone enhances cell invasion and colony formation of human head and neck cancer cells; this is accompanied by a downregulation of E-cadherin expression. More significantly, we found that the cell phone can activate Erk1/Erk2 in our experimental models. Our investigation reveals that cell-phone radiofrequency could enhance head and neck cancer by stimulating angiogenesis and cell invasion via Erk1/Erk2 activation. © 2018 Wiley Periodicals, Inc.

Positron emission tomography-computed tomography protocol considerations for head and neck cancer imaging.

Science.gov (United States)

Escott, Edward J

2008-08-01

Positron emission tomographic-computed tomographic (PET-CT) imaging of patients with primary head and neck cancers has become an established approach for staging and restaging, as well as radiation therapy planning. The inherent co-registration of PET and CT images made possible by the integrated PET-CT scanner is particularly valuable in head and neck cancer imaging due to the complex and closely situated anatomy in this part of the body, the varied sources of physiologic and benign 2-deoxy-2-[F-18]fluoro-D-glucose (FDG) tracer uptake that occurs in the neck, and the varied and complex posttreatment appearance of the neck. Careful optimization of both the CT and the PET portion of the examination is essential to insure the most accurate and clinically valuable interpretation of these examinations.

Intensity-Modulated Radiotherapy is Associated With Improved Global Quality of Life Among Long-term Survivors of Head-and-Neck Cancer

Chen, Allen M.; Farwell, D. Gregory; Luu, Quang; Vazquez, Esther G.; Lau, Derick H.; Purdy, James A.

2012-01-01

Purpose: To compare the long-term quality of life among patients treated with and without intensity-modulated radiotherapy (IMRT) for head-and-neck cancer. Methods and Materials: University of Washington Quality of Life instrument scores were reviewed for 155 patients previously treated with radiation therapy for locally advanced head-and-neck cancer. All patients were disease free and had at least 2 years of follow-up. Eighty-four patients (54%) were treated with IMRT. The remaining 71 patients (46%) were treated with three-dimensional conformal radiotherapy (3D CRT) by use of initial opposed lateral fields matched to a low anterior neck field. Results: The mean global quality of life scores were 67.5 and 80.1 for the IMRT patients at 1 and 2 years, respectively, compared with 55.4 and 57.0 for the 3D CRT patients, respectively (p < 0.001). At 1 year after the completion of radiation therapy, the proportion of patients who rated their global quality of life as “very good” or “outstanding” was 51% and 41% among patients treated by IMRT and 3DCRT, respectively (p = 0.11). At 2 years, the corresponding percentages increased to 73% and 49%, respectively (p < 0.001). On multivariate analysis accounting for sex, age, radiation intent (definitive vs. postoperative), radiation dose, T stage, primary site, use of concurrent chemotherapy, and neck dissection, the use of IMRT was the only variable independently associated with improved quality of life (p = 0.01). Conclusion: The early quality of life improvements associated with IMRT not only are maintained but apparently become more magnified over time. These data provide powerful evidence attesting to the long-term benefits of IMRT for head-and-neck cancer.

Emotions and coping of patients with head and neck cancers after diagnosis: A qualitative content analysis.

Science.gov (United States)

Jagannathan, A; Juvva, S

2016-01-01

Patients suffering with head and neck cancers are observed to have a relatively high risk of developing emotional disturbances after diagnosis and treatment. These emotional concerns can be best understood and explored through the method of content analysis or qualitative data. Though a number of qualitative studies have been conducted in the last few years in the field of psychosocial oncology, none have looked at the emotions experienced and the coping by head and neck cancer patients. Seventy-five new cases of postsurgery patients of head and neck cancers were qualitatively interviewed regarding the emotions experienced and coping strategies after diagnosis. Qualitative content analysis of the in-depth interviews brought out that patients experienced varied emotions on realizing that they were suffering from cancer, the cause of which could be mainly attributed to three themes: 1) knowledge of their illness; 2) duration of untreated illness; and 3) object of blame. They coped with their emotions by either: 1) inculcating a positive attitude and faith in the doctor/treatment, 2) ventilating their emotions with family and friends, or 3) indulging in activities to divert attention. The results brought out a conceptual framework, which showed that an in-depth understanding of the emotions - Their root cause, coping strategies, and spiritual and cultural orientations of the cancer survivor - Is essential to develop any effective intervention program in India.

2007-01-01

To evaluate the frequency of short-term pulmonary complications in the patients undergoing various head and neck cancer surgeries in our setup and to assess possible risk factors responsible for these complications. Seventy patients of age group 20 to 80 years, regardless of gender, treated surgically for head and neck cancers were enrolled. Main outcome measures included development of pulmonary complications following 15 days of oncological surgery. The complications studied were pneumothorax, bronchopneumonia, atelectasis, pulmonary embolism and cardiopulmonary arrest. A total of 24.28% patients suffered from postoperative pulmonary complications; 17.14% developed bronchopneumonia, 5.71% pulmonary embolism, and 1.42% went into cardiopulmonary arrest, none developed pneumothorax or pulmonary atelectasis. A significant correlation of postoperative bronchopneumonia was seen with heavy smoking and assisted ventilation. Pulmonary embolism was associated with extended assisted ventilation and prolonged surgery. Cardiopulmonary arrest was associated with comorbidity and assisted ventilation after surgery. The frequency of bronchopneumonia supersedes all of the postoperative pulmonary complications in head and neck oncological surgery. Patients at risk of developing postoperative complications are heavy smokers, diabetics, those undergoing prolonged surgery, tracheostomy, and extended assisted ventilation. (author)

The protective role of carotenoids and polyphenols in patients with head and neck cancer

Directory of Open Access Journals (Sweden)

Hui-Ping Chang

2015-02-01

Full Text Available Head and neck cancer is a critical global health problem and approximately 650,000 patients per year are diagnosed with this type of cancer. In addition, head and neck cancer exhibits a high recurrence rate, readily causing second primary cancers in other locations, often yielding a poor prognosis. Current medical and surgical treatment options result in considerable impairment of speaking and swallowing functions, with side effects such as nausea, vomiting, bone marrow suppression, and renal damage, thereby impairing patients' quality of life. Thus, developing a prevention and therapeutic intervention strategy for head and neck cancer is vital. Phytochemicals have been shown to have a unique ability to protect cells from damage and modulation of cell repair. The chemopreventive activities of phytochemicals have also been demonstrated to be associated with their antioxidant properties and the induction and stimulation of intercellular communication via gap junctions, which play a role in the regulation of cancer cell cycle, differentiation, apoptosis, and stagnate cancer cell growth. Phytochemicals can also regulate cancer cell signaling pathways, reduce the invasion and metastasis of cancer cells, and protect normal cells during treatment, thus reducing the damage caused by chemotherapy and radiotherapy. The most studied of the chemopreventive effects of phytochemicals are the carotenoids and phenolics. In this review, we investigated the multiple mechanisms of carotenoids and polyphenols (PPs for use in preventing head and neck cancer, reducing the side effects of chemotherapy and radiotherapy, improving patient survival rates, and reducing the occurrence rate of second primary cancers.

Lhermitte's Sign Developing after IMRT for Head and Neck Cancer

Dong C. Lim

2010-01-01

Full Text Available Background. Lhermitte's sign (LS is a benign form of myelopathy with neck flexion producing an unpleasant electric-shock sensation radiating down the extremities. Although rare, it can occur after head and neck radiotherapy. Results. We report a case of Lhermitte's developing after curative intensity-modulated radiotherapy (IMRT for a patient with locoregionally advanced oropharyngeal cancer. IMRT delivers a conformal dose of radiation in head and neck cancer resulting in a gradient of radiation dose throughout the spinal cord. Using IMRT, more dose is delivered to the anterior spinal cord than the posterior cord. Conclusions. Lhermitte's sign can develop after IMRT for head and neck cancer. We propose an anterior spinal cord structure, the spinothalamic tract to be the target of IMRT-caused LS.

Purpose: The purpose of this study was to measure the effect of megestrol acetate (MA) on weight loss and quality of life (QOL) in patients with cancer of the lung or head and neck undergoing curative radiation therapy. Methods and Materials: This was a Phase III, placebo-controlled, double-blind randomized study. Patients received either 800 mg/day of MA (20 milliliters po qAM) or placebo over a 12-week period. Patients received radiation of the head and neck or thorax using a dose of at least 50 Gy, either alone or with chemotherapy. Weight was assessed weekly, whereas QOL was assessed at baseline and at 4, 8, and 12 weeks. Results: Patient characteristics on the MA arm (16 lung, 12 head/neck; mean age: 60 years) were similar to those on the placebo arm (17 lung, 11 head/neck; mean age: 65.8 years). Patients in the MA group had a mean weight loss over 12 weeks of 2.7 pounds, whereas the placebo group had a mean weight loss of 10.6 pounds. There was a significant time by treatment interaction (p=0.001), with the difference in weight between treatment groups being most pronounced after 6 weeks. Although overall QOL was similar in both arms of the study, several QOL subscale items did differ significantly. Compared to the placebo-treated patients, head-and-neck cancer patients in the MA arm reported the ability to eat as much as they liked (p=0.02 at 12 weeks), and lung cancer patients in the MA arm reported significantly better appetite at 4 weeks (p=0.03) and 8 weeks (p=0.001). Conclusion: MA used prophylactically is useful as an appetite stimulant; it can help patients maintain weight over the course of curative radiotherapy of the head and neck or lung and can improve specific aspects of QOL

There is considerable debate within the literature about the significance of human papilloma virus in head and neck squamous cell carcinoma, and its potential influence on the prevention, diagnosis, grading, treatment and prognosis of these cancers. Cigarette smoking and alcohol consumption have traditionally been cited as the main risk factors for head and neck cancers. However, human papilloma virus, normally associated with cervical and other genital carcinomas, has emerged as a possible key aetiological factor in head and neck squamous cell carcinoma, especially oropharyngeal cancers. These cancers pose a significant financial burden on health resources and are increasing in incidence. The recent introduction of vaccines targeted against human papilloma virus types 16 and 18, to prevent cervical cancer, has highlighted the need for ongoing research into the importance of human papilloma virus in head and neck squamous cell carcinoma.

Purpose: To present a retrospective review of treatment outcomes for recurrent head and neck (HN) cancer patients treated with re-irradiation (re-RT) at a single medical center. Methods and Materials: From July 1996-September 2005, 105 patients with recurrent HN cancer underwent re-RT at our institution. Sites included were: the neck (n = 21), nasopharynx (n 21), paranasal sinus (n = 18), oropharynx (n = 16), oral cavity (n = 9), larynx (n = 10), parotid (n = 6), and hypopharynx (n = 4). The median prior RT dose was 62 Gy. Seventy-five patients received chemotherapy with their re-RT (platinum-based in the majority of cases). The median re-RT dose was 59.4 Gy. In 74 (70%), re-RT utilized intensity-modulated radiation therapy (IMRT). Results: With a median follow-up of 35 months, 18 patients were alive with no evidence of disease. The 2-year loco-regional progression-free survival (LRPFS) and overall survival rates were 42% and 37%, respectively. Patients who underwent IMRT, compared to those who did not, had a better 2-year LRPF (52% vs. 20%, p < 0.001). On multivariate analysis, non-nasopharynx and non-IMRT were associated with an increased risk of loco-regional (LR) failure. Patients with LR progression-free disease had better 2-year overall survival vs. those with LR failure (56% vs. 21%, p < 0.001). Acute and late Grade 3-4 toxicities were reported in 23% and 15% of patients. Severe Grade 3-4 late complications were observed in 12 patients, with a median time to development of 6 months after re-RT. Conclusions: Based on our data, achieving LR control is crucial for improved overall survival in this patient population. The use of IMRT predicted better LR tumor control. Future aggressive efforts in maximizing tumor control in the recurrent setting, including dose escalation with IMRT and improved chemotherapy, are warranted

Patients with head and neck cancer can report reduced health-related quality of life several years after treatment. The aim of this study was to identify risk factors for reduced quality of life in patients up to 5 years following neck dissection. This cross-sectional study was conducted at two hospitals in Brisbane, Australia. Patients completed two measures of quality of life: the Neck Dissection Impairment Index (NDII), a region- and disease-specific tool, and the Assessment of Quality of Life-4 Domains, a general tool. Generalised linear modelling was used to determine which demographic and clinical variables were associated with quality of life. The cohort included n = 129 patients (71% male, median age 61, median 3 years since surgery). Positive nodal disease was associated with better quality of life on the NDII [e.g. N2 vs N0 coeff (95% CI) = 22.84 (7.33, 38.37)]. Worse quality of life was associated with adjuvant treatment [e.g. Independent Living domain model: surgery with chemoradiation vs surgery only coeff (95% CI) = -0.11 (-0.22, -0.01)]. Positive nodal disease was associated with better quality of life, which may be a reflection of response shift. Multimodality treatment leads to worse quality of life compared with surgery only.

The five-year survival rates for head and neck squamous cell carcinoma (HNSCC) patients are less than 50%, and the prognosis has not improved, despite advancements in standard multi-modality therapies. Hence major emphasis is being laid on identification of novel molecular targets and development of multi-targeted therapies. 14-3-3 zeta, a multifunctional phospho-serine/phospho-threonine binding protein, is emerging as an effector of pro-survival signaling by binding to several proteins involved in apoptosis (Bad, FKHRL1 and ASK1) and may serve as an appropriate target for head and neck cancer therapy. Herein, we determined effect of guggulsterone (GS), a farnesoid X receptor antagonist, on 14-3-3 zeta associated molecular pathways for abrogation of apoptosis in head and neck cancer cells. Head and neck cancer cells were treated with guggulsterone (GS). Effect of GS-treatment was evaluated using cell viability (MTT) assay and apoptosis was verified by annexin V, DNA fragmentation and M30 CytoDeath antibody assay. Mechanism of GS-induced apoptosis was determined by western blotting and co-IP assays using specific antibodies. Using in vitro models of head and neck cancer, we showed 14-3-3 zeta as a key player regulating apoptosis in GS treated SCC4 cells. Treatment with GS releases BAD from the inhibitory action of 14-3-3 zeta in proliferating HNSCC cells by activating protein phosphatase 2A (PP2A). These events initiate the intrinsic mitochondrial pathway of apoptosis, as revealed by increased levels of cytochrome c in cytoplasmic extracts of GS-treated SCC4 cells. In addition, GS treatment significantly reduced the expression of anti-apoptotic proteins, Bcl-2, xIAP, Mcl1, survivin, cyclin D1 and c-myc, thus committing cells to apoptosis. These events were followed by activation of caspase 9, caspase 8 and caspase 3 leading to cleavage of its downstream target, poly-ADP-ribose phosphate (PARP). GS targets 14-3-3 zeta associated cellular pathways for reducing

Oral and neck examination for early detection of oral cancer--a practical guide.

MacCarthy, Denise

2011-08-01

Cancer of the head and neck region presents a challenge since, unlike other areas of the body, the boundaries are not always easy to delineate. The functional morbidity associated with head and neck cancer and its treatment are considerable. Head and neck cancer is described as cancer of the lip, mouth, tongue, tonsil, pharynx (unspecified), salivary gland, hypopharynx, larynx and other. Oral cancer refers to cancers of the lip, tongue, gingivae, floor of the mouth, palate (hard and soft), maxilla, vestibule and retromolar area up to the anterior pillar of the fauces (tonsil). When patients present with oral cancer, over 60% of them have regional (lymph node) and sometimes distant (metastatic) spread. The overall five-year survival rates for oral cancer average at between 50 and 80%, depending on the stage of the disease, varying from 86% for stage I to 12-16% for stage IV. The incidence of \\'field cancerisation\\'\\/unstable oral epithelium is high (17%), and even after successful treatment our patients need to be monitored for dental care and further disease. Unlike other areas in the body, the oral epithelium is readily accessible for examination and even self-examination. Dentists and dental hygienists are effective clinicians in the examination of the oral cavity for mouth cancer. An oral and neck examination must be part of every dental examination. An examination protocol is suggested here, which is similar to, but more detailed than, the standardised oral examination method recommended by the World Health Organisation, and consistent with those protocols followed by the Centres for Disease Control and Prevention and the National Institutes of Health.

Central and South America comprise one of the areas characterized by high incidence rates for head and neck cancer. We describe the geographical and temporal trends in incidence and mortality of head and neck cancers in the Central and South American region in order to identify opportunities for intervention on the major identified risk factors: tobacco control, alcohol use and viral infections. We obtained regional- and national-level incidence data from 48 population-based cancer registries in 13 countries and cancer deaths from the WHO mortality database for 18 countries. Age-standardized incidence (ASR) and mortality (ASMR) rates per 100,000 person-years were estimated. Brazil had the highest incidence rates for oral and pharyngeal cancer in the region for both sexes, followed by Cuba, Uruguay and Argentina. Cuba had the highest incidence and mortality rates of laryngeal cancer in the region for males and females. Overall, males had rates about four times higher than those in females. Most countries in the region have implemented WHO recommendations for both tobacco and alcohol public policy control. Head and neck squamous-cell cancer (HNSCC) incidence and mortality rates in the Central and South America region vary considerably across countries, with Brazil, Cuba, French Guyana, Uruguay and Argentina experiencing the highest rates in the region. Males carry most of the HNSCC burden. Improvement and implementation of comprehensive tobacco and alcohol control policies as well as the monitoring of these factors are fundamental to prevention of head and neck cancers in the region.

Poor oral hygiene has been proposed to contribute to head and neck cancer (HNC) risk, although causality and independency of some indicators are uncertain. This study investigates the relationship of five oral hygiene indicators with incident HNCs. In a pooled analysis of 8925 HNC cases and 12 527 controls from 13 studies participating in the International Head and Neck Cancer Epidemiology Consortium, comparable data on good oral hygiene indicators were harmonized. These included: no denture wear, no gum disease (or bleeding), oral hygiene indicator and cumulative score on HNC risk, adjusting for tobacco smoking and alcohol consumption. Inverse associations with any HNC, in the hypothesized direction, were observed for cancer sites, especially for tooth brushing and dentist visits. The population attributable fraction for ≤ 2 out of 5 good oral hygiene indicators was 8.9% (95% CI 3.3%, 14%) for oral cavity cancer. Good oral hygiene, as characterized by few missing teeth, annual dentist visits, and daily tooth brushing, may modestly reduce the risk of HNC. © The Author 2016.

Epidemiological and clinical analysis of lymphoid tissue neoplasms in the neck region over a 15-year period. There was performed retrospective analysis of 97 patients, aged 17 to 88 years, mean age of 60.3 years. The analysis included data from subjective study, physical examination, image and histopathological studies Results: Almost all cases were lymphoid neoplasms - 95 patients (98%). B cell lymphoma was the most commonly diagnosed lymphoma - 74 cases (76%), followed by Hodgkin's lymphoma- 19 cases (20%). Only two patients had T-cell lymphoma (2%). There was observed prevalence among women, K: M ratio for the whole group was 51: 46, while male predominance was reported in Hodgkin's lymphoma patients (K: M = 7: 12). Over the 15-year period, there was an increase in the number of lymphoid tumors. The most common location on the neck were lymph nodes - 71 (73.2%). Extranodal localizations (26.8%) were most often associated with salivary glands: parotid and submandibular involvement and with the dominant lymphoma of the marginal zone MALT (14 cases). In 57% of patients the fine needle aspiration biopsy (FNAB) results were false, with positive results only in 32% of patients. Tumors from lymphoid tissue in the neck region are most commonly B-cell lymphomas or Hodgkin,s lymphomas. Non-specific clinical signs and non-specific radiological images, as well as non-diagnostic results o FNAB, make it difficult to effectively differentiate lymphomas with cancer metastasis in neck lymph nodes. Histopathology results of the excised lymph nodes remains a standard for lymphoma diagnosis.

To investigate the feasibility, and safety of {sup 125}I seed permanent implantation for recurrent head and neck carcinoma under CT-guidance. A retrospective study on 14 patients with recurrent head and neck cancers undergone {sup 125}I seed implantation with different seed activities. The post-plan showed that the actuarial D90 of {sup 125}I seeds ranged from 90 to 218 Gy (median, 157.5 Gy). The follow-up was 3 to 60 months (median, 13 months). The median local control was 18 months (95% CI, 6.1-29.9 months), and the 1-, 2-, 3-, and 5- year local controls were 52%, 39%, 39%, and 39%, respectively. The 1-, 2-, 3-, and 5- survival rates were 65%, 39%, 39% and 39%, respectively, with a median survival time of 20 months (95% CI, 8.7-31.3 months). Of all patients, 28.6% (4/14) died of local recurrence, 7.1% (1/14) died of metastases, one patient died of hepatocirrhosis, and 8 patients are still alive to the date of data analysis. CT-guided {sup 125}I seed implantation is feasible and safe as a salvage or palliative treatment for patients with recurrent head and neck cancers.

Studies for head and neck cancer have primarily relied on cell lines or in vivo animal studies. However, a technique that combines the benefits of high-throughput in vitro studies with a complex, physiologically relevant microenvironment would be advantageous for understanding drug effects. Organoids provide a unique platform that fulfills these goals. Organoids are generated from excised and digested tumor tissue and are grown in culture. Fluorescence microscopy provides high-resolution images on a similar spatial scale as organoids. In particular, autofluorescence imaging of the metabolic cofactors NAD(P)H and FAD can provide insight into response to anti-cancer treatment. The optical redox ratio reflects relative amounts of NAD(P)H and FAD, and the fluorescence lifetime reflects enzyme activity of NAD(P)H and FAD. This study optimizes and characterizes the generation and culture of organoids grown from head and neck cancer tissue. Additionally, organoids were treated for 24 hours with a standard chemotherapy, and metabolic response in the organoids was measured using optical metabolic imaging. Ultimately, combining head and neck cancer organoids with optical metabolic imaging could be applied to test drug sensitivity for drug development studies as well as treatment planning for cancer patients.

The purpose of this study is to demonstrate dental problems such as changes of saliva flow rates (ml/min), taste sensation and DMF-teeth (D: decay, M: missing, F: filling) after radiation therapy for the patients with head and neck cancer. Between January 1990 and April 1995, a total of 56 patients with head and neck cancer after radiation therapy was reviewed to demonstrate dental problems at the Department of Oral Radiology, Osaka Dental University Hospital. The results were as follows. In the case of 7 inpatients with head and neck cancer (nasopharynx: 3, mouth floor: 2, tongue: 2), non-stimulating saliva flow rates for 5 minutes was nearly equal to 0 ml at the level of 60 Gy/6 weeks to 80 Gy/8 weeks. In the scoring system of the taste sensation after radiation therapy for 23 patients with oral cancer (tongue: 18, mouth floor: 5), distribution of the patients with 3 points (3 points stand for patients feel good as well as pretreatment) was 91% for sweetness, 78% for sharpness, 96% for bitterness and 96% for acidity, respectively. Concerning DMF-teeth after radiation therapy for 26 patients with head and neck cancer (nasopharynx: 10, oropharynx: 8, tongue: 8), changes of DMF-Teeth of the group of nasopharynx and oropharynx was more higher than that of the group of tongue comparing to report on the survey of dental diseases in Japan, 1993 as control. We emphasize that these data are more effective to improve their oral environments and to up their recognition for oral cavity in the patients with head and neck cancer pre or post-irradiation.

2017-12-01

Up to 80% of patients with head and neck cancers are malnourished because of their lifestyle and the risk factors associated with this disease. Unfortunately, nutrition management systems are not implemented in most head and neck cancer clinics. Even worse, many head and neck surgeons as well as hospital management authorities disregard the importance of nutrition management in head and neck cancer patients. In addition, the often extensive resection and reconstruction required for tumors in the upper aerodigestive tract pose special challenges for swallowing and sufficient food intake, placing special demands on nutrition management. This article presents the basics of perioperative metabolism and nutrition management of head and neck cancer patients and makes recommendations for clinical practice. Implementing a nutrition management system in head and neck cancer clinics will improve the clinical outcome and the survival of the patients. Copyright © 2017 Elsevier Inc. All rights reserved.

Nguyen, N.P.; Chi, A.; Vock, J.

2012-01-01

Purpose: In this work, the treatment tolerance of elderly patients (≥ 70 years) undergoing intensity-modulated radiotherapy (IMRT) and image-guided radiotherapy (IGRT) and chemotherapy for locally advanced head and neck cancer was assessed. Patients and methods: A retrospective review of 112 patients undergoing concurrent chemoradiation for locally advanced head and neck cancer was performed. Treatment toxicity, protocol violations, long-term complications, and survival were compared between 85 younger patients (< 70 years) and 27 older patients (≥ 70 years). Results: Grade 3-4 treatment toxicity was observed in 88.2% and 88.8% for younger and older patients, respectively. Mean weight loss and treatment break were 5.9 and 3.9 kg (p = 0.03) and 7.3 and 7.8 days (p = 0.8) for younger and older patients, respectively. Seven patients (8.2%) did not complete treatment in the younger group compared to 1 patient (3.7%) in the older group (p = 0.6). No significant differences in protocol violations and survival were found between the two groups. Conclusion: Compared to younger patients, elderly patients with locally advanced head and neck cancer tolerated chemoradiation with IMRT and IGRT well, and should not be denied curative treatment based solely on age.

The purpose of the study was to evaluate [{sup 18}F]fluoromisonidazole (FMISO) PET in advanced head and neck cancer during hypoxia-targeting therapy. Fifteen of 16 patients in a phase I trial of chemoradiation plus tirapazamine (specific cytotoxin for hypoxic cells) in advanced (T3/4 and/or N2/3) head and neck cancer underwent serial [{sup 18}F]fluorodeoxyglucose (FDG) and FMISO PET. We have previously reported excellent early clinical outcome of these patients and now review FMISO PET results in the context of longer follow-up of this patient cohort. Based on blinded qualitative scoring by two readers, FMISO PET was positive in 13/15 patients at baseline: 12/15 of primary sites and 8/13 neck nodes were scored as positive. All sites of corresponding FDG and FMISO abnormality at baseline showed marked qualitative reduction of uptake within 4 weeks of commencing therapy, consistent with effective hypoxia-targeted therapy. With a median follow-up of 6.9 years, there have been only four locoregional failures, while three other patients have died of metachronous lung cancer. The 5-year overall survival was 50% (95% CI 27-73%), the 5-year failure-free survival was 44% (95% CI 22-68%) and the 5-year freedom from locoregional failure was 68% (95% CI 38-88%). The high prevalence of hypoxia demonstrated on FMISO PET imaging is consistent with the advanced disease stage of these patients and would be expected to predict an adverse prognosis. Evidence of the early resolution of FMISO abnormality during treatment, associated with excellent locoregional control in this patient cohort, supports further investigation of hypoxia-targeting agents in advanced head and neck cancer.

Purpose: To compare the long-term outcome of treatment with concomitant cisplatin and hyperfractionated radiotherapy versus treatment with hyperfractionated radiotherapy alone in patients with locally advanced head and neck cancer. Methods and Materials: From July 1994 to July 2000, a total of 224 patients with squamous cell carcinoma of the head and neck were randomized to receive either hyperfractionated radiotherapy alone (median total dose, 74.4 Gy; 1.2 Gy twice daily; 5 days per week) or the same radiotherapy combined with two cycles of cisplatin (20 mg/m 2 for 5 consecutive days during weeks 1 and 5). The primary endpoint was the time to any treatment failure; secondary endpoints were locoregional failure, metastatic failure, overall survival, and late toxicity assessed according to Radiation Therapy Oncology Group criteria. Results: Median follow-up was 9.5 years (range, 0.1–15.4 years). Median time to any treatment failure was not significantly different between treatment arms (hazard ratio [HR], 1.2 [95% confidence interval {CI}, 0.9–1.7; p = 0.17]). Rates of locoregional failure-free survival (HR, 1.5 [95% CI, 1.1–2.1; p = 0.02]), distant metastasis-free survival (HR, 1.6 [95% CI, 1.1–2.5; p = 0.02]), and cancer-specific survival (HR, 1.6 [95% CI, 1.0–2.5; p = 0.03]) were significantly improved in the combined-treatment arm, with no difference in major late toxicity between treatment arms. However, overall survival was not significantly different (HR, 1.3 [95% CI, 0.9–1.8; p = 0.11]). Conclusions: After long-term follow-up, combined-treatment with cisplatin and hyperfractionated radiotherapy maintained improved rates of locoregional control, distant metastasis-free survival, and cancer-specific survival compared to that of hyperfractionated radiotherapy alone, with no difference in major late toxicity.

Purpose: The objective of this study was to determine regional control of local regional advanced head and neck squamous cell carcinoma (HNSCC) treated with intensity-modulated radiotherapy (IMRT), along with the role and selection criteria for neck dissection after IMRT. Methods and Materials: A total of 90 patients with stage N2A or greater HNSCC were treated with definitive IMRT from December 1999 to July 2005. Three clinical target volumes were defined and were treated to 70 to 74 Gy, 60 Gy, and 54 Gy, respectively. Neck dissection was performed for selected patients after IMRT. Selection criteria evolved during this period with emphasis on post-IMRT [ 18 F] fluorodeoxyglucose positron emission tomography in recent years. Results: Median follow-up for all patients was 29 months (range, 0.2-74 months). All living patients were followed at least 9 months after completing treatment. Thirteen patients underwent neck dissection after IMRT because of residual lymphadenopathy. Of these, 6 contained residual viable tumor. Three patients with persistent adenopathy did not undergo neck dissection: 2 refused and 1 had lung metastasis. Among the remaining 74 patients who were observed without neck dissection, there was only 1 case of regional failure. Among all 90 patients in this study, the 3-year local and regional control was 96.3% and 95.4%, respectively. Conclusions: Appropriately delivered IMRT has excellent dose coverage for cervical lymph nodes. A high radiation dose can be safely delivered to the abnormal lymph nodes. There is a high complete response rate. Routine planned neck dissection for patients with N2A and higher stage after IMRT is not necessary. Post-IMRT [ 18 F] fluorodeoxyglucose positron emission tomography is a useful tool in selecting patients appropriate for neck dissection

Purpose: To investigate the association of pretreatment body mass index (preT BMI) with outcomes of head-and-neck cancer in patients treated with radiotherapy (RT). Methods and Materials: All 1,562 patients diagnosed with head-and-neck cancer and treated with curative-intent RT to a dose of 60 Gy or higher were retrospectively studied. Body weight was measured both at entry and at the end of RT. Cancer-specific survival (CSS), overall survival (OS), locoregional control (LRC), and distant metastasis (DM) were analyzed by preT BMI ( 2 vs. ≥25 kg/m 2 ). The median follow-up was 8.6 years. Results: Patients with lower preT BMI were statistically significantly associated with poorer CSS and OS than those with higher preT BMI. There was no significant difference between preT BMI groups in terms of LRC and DM. Body weight loss (BWL) during radiation did not influence survival outcomes. However, in the group with higher preT BMI, CSS, OS, and DM-free survival of patients with less BWL during radiation were statistically longer when compared with greater BWL. Conclusion: This study demonstrates that higher preT BMI positively influenced survival outcomes for patients with head-and-neck cancer. Patients with higher preT BMI who were able to maintain their weight during radiation had significantly better survival than patients with greater BWL.

Full Text Available Abstract This review concentrates on tumours that are anatomically localised in head and neck regions. Brain cancers and head and neck cancers together account for more than 873,000 cases annually worldwide, with an increasing incidence each year. With poor survival rates at late stages, brain and head and neck cancers represent serious conditions. Carcinogenesis is a multi-step process and the role of infectious agents in this progression has not been fully identified. A major problem with such research is that the role of many infectious agents may be underestimated due to the lack of or inconsistency in experimental data obtained globally. In the case of brain cancer, no infection has been accepted as directly oncogenic, although a number of viruses and parasites are associated with the malignancy. Our analysis of the literature showed the presence of human cytomegalovirus (HCMV in distinct types of brain tumour, namely glioblastoma multiforme (GBM and medulloblastoma. In particular, there are reports of viral protein in up to 100% of GBM specimens. Several epidemiological studies reported associations of brain cancer and toxoplasmosis seropositivity. In head and neck cancers, there is a distinct correlation between Epstein-Barr virus (EBV and nasopharyngeal carcinoma (NPC. Considering that almost every undifferentiated NPC is EBV-positive, virus titer levels can be measured to screen high-risk populations. In addition there is an apparent association between human papilloma virus (HPV and head and neck squamous cell carcinoma (HNSCC; specifically, 26% of HNSCCs are positive for HPV. HPV type 16 was the most common type detected in HNSCCs (90% and its dominance is even greater than that reported in cervical carcinoma. Although there are many studies showing an association of infectious agents with cancer, with various levels of involvement and either a direct or indirect causative effect, there is a scarcity of articles covering the role of

Post-operative radiation therapy for advanced head and neck cancers

Ang, Kian K.; Garden, Adam S.

Purpose: To discuss both general and specific indications for radiation following surgery for patients with cancers of the head and neck. Patients with advanced cancers of the head and neck are often not suitable candidates for treatment with definitive radiation, and are treated with surgery. Frequently these patients fail by recurring in either the primary sites or in the necks. Adjuvant radiation is therefore often a critical component in the management of these patients. While radiation can be done either prior to or after surgery, most centers prefer the postoperative setting. This refresher course will review general concepts of postoperative irradiation for the patient with head and neck cancer and apply these concepts to specific situations. The course will begin with a broad review of the indications for postoperative irradiation as not all patients undergoing surgery for cancers of the head and neck require additional treatment. We will also review the concept of using postoperative radiation to allow for more conservative surgery with preservation of function. The second portion of the course will focus on general techniques of postoperative irradiation. We will review concepts of patient setup and treatment portal design and describe how specific techniques are practiced at MDACC. Controversial topics, including field matching, total dose and fractionation, and the timing of postoperative radiation will be discussed. The final section of the course will review the results of postoperative irradiation as applied to the head and neck in general as well as to specific subsites. In addition to results for the common scenarios of squamous cell carcinomas of the oral cavity, pharynx and larynx, we will review results of postoperative irradiation for skin cancers of the head and neck, paranasal sinuses, and salivary glands

[Managment of head and neck cancers during pregnancy].

The coincidence of malignant disease during pregnancy is uncommon. The incidence of cancer in pregnancy has increased, due to the tendency to postpone childbirth to an older age. Cancer complicates approximately 0.1% of all pregnancies. Managing head and neck cancers during pregnancy requires additional pregnancy-related understanding of the aetiological effect of pregnancy on cancer, knowledge of the direct and indirect effects of cancer on pregnancy, and the effect of diagnostic and treatment modalities on pregnancy. The timing of treatment is an important determinant on foetal wellbeing. A multidisciplinary approach should be adopted to enable parents and clinicians to make the best clinical decision. Clinicians must be cognizant with the ethical dilemmas of treatment. In head and neck cancers, pregnancy has no effect on maternal prognosis when compared to non-pregnant patients matched by age, cancer stage and treatment.

2014-01-01

To investigate predictors affecting the development of hypothyroidism after radiotherapy for head and neck cancer, focusing on radiation dose-volumetric parameters, and to determine the appropriate radiation dose-volumetric threshold of radiation-induced hypothyroidism. A total of 114 patients with head and neck cancer whose radiotherapy fields included the thyroid gland were analysed. The purpose of the radiotherapy was either definitive (n=81) or post-operative (n=33). Thyroid function was monitored before starting radiotherapy and after completion of radiotherapy at 1 month, 6 months, 1 year and 2 years. A diagnosis of hypothyroidism was based on a thyroid stimulating hormone value greater than the maximum value of laboratory range, regardless of symptoms. In all patients, dose volumetric parameters were analysed. Median follow-up duration was 25 months (range; 6-38). Forty-six percent of the patients were diagnosed as hypothyroidism after a median time of 8 months (range; 1-24). There were no significant differences in the distribution of age, gender, surgery, radiotherapy technique and chemotherapy between the euthyroid group and the hypothyroid group. In univariate analysis, the mean dose and V35-V50 results were significantly associated with hypothyroidism. The V45 is the only variable that independently contributes to the prediction of hypothyroidism in multivariate analysis and V45 of 50% was a threshold value. If V45 was <50%, the cumulative incidence of hypothyroidism at 1 year was 22.8%, whereas the incidence was 56.1% if V45 was ≥50%. (P=0.034). The V45 may predict risk of developing hypothyroidism after radiotherapy for head and neck cancer, and a V45 of 50% can be a useful dose-volumetric threshold of radiation-induced hypothyroidism.

The purpose of this study was to evaluate the efficacy of CyberKnife for recurrent previously irradiated head and neck cancer. Thirty-one patients with recurrent previously irradiated head and neck cancer were treated with a CyberKnife from July 1999 to March 2002 at Okayama Kyokuto Hospital were retrospectively studied. The accumulated dose was 28-80 Gy (median 60 Gy). The interval between CyberKnife treatment and previous radiotherapy was 0.4-429.5 months (median 16.3 months). Primary lesions were nasopharynx: 7, maxillary sinus: 6, tongue: 5, ethmoid sinus: 3, and others: 1. The pathology was squamous cell carcinoma: 25, adenoid cystic carcinoma: 4, and others: 2. Symptoms were pain: 8, and nasal bleeding: 2. The prescribed dose was 15.0-40.3 Gy (median 32.3 Gy) as for the marginal dose. The response rate (complete response (CR)+partial response (PR)) and local control rate (CR+PR+no change (NC)) was 74% and 94% respectively. Pain disappeared for 4 cases, relief was obtained for 4 cases and no change for 2 cases and nasal bleeding disappeared for 2 cases for an improvement of symptoms. An adverse effects were observed as mucositis in 5 cases and neck swelling in one case. Prognosis of recurrent previously irradiated head and neck cancer was estimated as poor. Our early experience shows that CyberKnife is expected to be feasible treatment for recurrent previously irradiated head and neck cancer, and for the reduction adverse effects and maintenance of useful quality of life (QOL) for patients.

Treatment results of neck dissection with the preservation of cervical nerves for hypopharyngeal cancer were analyzed retrospectively by comparing neck dissection with the preservation of cervical nerves and that with the resection of cervical nerves. Pharyngolaryngectomy or pharyngolaryngoesophagectomy with bilateral neck dissection was performed in 76 hypopharyngeal cancer cases between January 1992 and November 2001. Neck dissection with the resection of cervical nerves was performed on 42 sides of the neck in 21 cases (the cervical nerve-resected group). In 55 cases we attempted to employ neck dissection with the preservation of cervical nerves, but in 9 cases the cervical nerves were resected because of their nodal adhesion or involvement Neck dissection with the preservation of cervical nerves was performed on 92 sides of the neck in 46 cases (the cervical nerve-preserved group). There were significant differences between background factors of two groups about age, sex, induction chemotherapy, preservation of accessory nerve, and pN classification. The 5-year cumulative control rates of cervical lymph nodes were 81.3% for the cervical nerve-resected group and 79.7% for the cervical nerve-preserved group. There was no significant difference between the two groups. It was suggested that neck dissection with the preservation of cervical nerves for cases whose cervical nerves were able to be preserved from metastatic lymph nodes under induction chemotherapy and post-operative irradiation was as effective to control cervical lymph nodes as neck dissection with the resection of cervical nerves.

Full Text Available AIM: To evaluate the role of palliative radiotherapy for symptom control in patients with locally advanced head and neck cancer. MATERIALS AND METHODS: 25 patients with stage 3 and stage 4 head and neck cancer were treated with a short course of palliative radiotherapy (30 Gray (Gy in 10 fractions over 2 weeks. Baseline symptoms were assessed using a 11 point numerical scale for pain, dysphagia, cough, insomnia and dyspnoea. The primary end point was relief of symptoms in the fourth week after radiotherapy. Percentage symptom relief was quantified by the patient using a rupee scale. RESULTS: All 22 patients with pain and 90% of patients with dysphagia, dyspnoea and disturbed sleep had greater than 50% relief in symptoms after radiotherapy. Cough was relieved in sixty percent of cases. CONCLUSION: A short course of radiation can be an effective method of symptom palliation in head and neck cancers.

Targeted therapies and radiation for the treatment of head and neck cancer

The purpose of this review is to provide an update on novel radiation treatments for head and neck cancer. Despite the remarkable advances in chemotherapy and radiotherapy techniques, the management of advanced head and neck cancer remains challenging. Epidermal growth factor receptor (EGFR) is an appealing target for novel therapies in head and neck cancer because not only EGFR activation stimulates many important signaling pathways associated with cancer development and progression, and importantly, resistance to radiation. Furthermore, EGFR overexpression is known to be portended for a worse outcome in patients with advanced head and neck cancer. Two categories of compounds designed to abrogate EGFR signaling, such as monoclonal antibodies (Cetuximab) and tyrosine kinase inhibitors (ZD1839 and OSI-774) have been assessed and have been most extensively studied in preclinical models and clinical trials. Additional TKIs in clinical trials include a reversible agent, Cl-1033, which blocks activation of all erbB receptors. Encouraging preclinical data for head and neck cancers resulted in rapid translation into the clinic. Results from initial clinical trials show rather surprisingly that only minority of patients benefited from EGFR inhibition as monotherapy or in combination with chemotherapy. In this review, we begin with a brief summary of erbB-mediated signal transduction. Subsequently, we present data on prognostic-predictive value of erbB receptor expression in HNC followed by preclinical and clinical data on the role of EGFR antagonists alone or in combination with radiation in the treatment of HNC. Finally, we discuss the emerging thoughts on resistance to EGFR blockade and efforts in the development of multiple-targeted therapy for combination with chemotherapy or radiation. Current challenges for investigators are to determine (1) who will benefit from targeted agents and which agents are most appropriate to combine with radiation and/or chemotherapy, (2

Objective: To evaluate 18 F-deoxyglucose-positron emission tomography (FDG-PET) in the detection of suspicious recurrence in head and neck cancers, as compared with CT/MRI imaging. Methods: Thirty-seven patients with clinically suspicious recurrences in head and neck cancers underwent FDG-PET, with 34 checked with CT/MRI imaging. The final diagnosis of recurrence were proved by pathology or clinical following-up. Results: FDG-PET detected recurrence successfully in 32 of 37 (86.5%) patients with 3 false positives and 2 false negatives. The FDG-PET sensitivity, specificity and accuracy in defining local recurrence were 91.7%, 76.9%, 86.5%, respectively; and those of CT/MRI were 68.2%, 75.0%, 61.8%, respectively. Conclusion: In comparison with CT/MRI, FDG-PET possesses a high accuracy in detecting recurrence in head and neck cancers

To explore the effect that treatment-related commuting has on carers of patients with head and neck cancer. Semi-structured interviews, thematically analysed, with 31 carers. Treatment-related commuting had a considerable impact on carers of patients with head and neck cancer, both in practical terms (economic costs, disruption) and also in psychological terms. Many carers of patients with head and neck cancer described becoming distressed by their commute. Some carers from large urban cities appeared to have hidden commuting burdens. Some carers respond to commuting stress by 'zoning out' or becoming 'like zombies'. Treatment-related travel for head and neck cancer can have significant practical and psychological impacts. Health professionals should be aware of the impacts that commuting can have on head and neck caregivers. Health services may be able to take practical steps, such as providing subsidized parking, to address head and neck carergivers' difficulties. Copyright © 2017 Elsevier Ltd. All rights reserved.

Swing of the Surgical Pendulum: A Return to Surgery for Treatment of Head and Neck Cancer in the 21st Century?

Holsinger, F. Christopher; Weber, Randal S.

2007-01-01

Treatment for head and neck cancer has evolved significantly during the past 100 years. Beginning with Bilroth's total laryngectomy on New Year's Day in 1873, 'radical' surgery remained the only accepted treatment for head and neck cancer when optimal local and regional control was the goal. Bigger was still better when it came to managing the primary tumor and the neck. The 'commando' procedure and radical neck dissection were the hallmarks of this first generation of treatments of head-and-neck cancer. With the advent of microvascular reconstructive techniques, larger and more comprehensive resections could be performed. Despite these large resections and their 'mutilating' sequelae, overall survival did not improve. Even for intermediate-stage disease in head-and-neck cancer, the 5-year survival rate did not improve >50%. Many concluded that more than the scalpel was needed for optimal local and regional control, especially for intermediate- and advanced-stage disease. Most important, the multidisciplinary teams must identify and correlate biomarkers in the tumor and host that predict for a response to therapy and for optimal functional recovery. As the pendulum swings back, a scientific approach using tissue biomarkers for the response to treatment in the setting of multidisciplinary trials must emerge as the new paradigm. In the postgenomic era, treatment decisions should be made based on functional and oncologic parameters-not just to avoid perceived morbidity

To investigate the feasibility of the bipaddled split pectoralis major myocutaneous flap for immediate reconstruction of oral mucosal defects and neck defects after resection of recurrent oral cancer. Six patients with oral mucosal defects combined with neck defects after recurrent oral cancer resection were treated with bipaddled split pectoralis major myocutaneous flap between September 2013 and September 2014. There were 5 males and 1 female with an average age of 54.7 years (range, 45-62 years), including 4 cases of recurrent tongue cancer, 1 case of recurrent mandibular gingival cancer, and 1 case of mouth floor carcinoma. All patients underwent local recurrence at 8 to 14 months after first operation, with no distant metastasis. The defects of the intraoral mucosa was 4.0 cm x 2.5 cm to 6.5 cm x 3.5 cm and the defect of the neck skin was 5.5 cm x 3.5 cm to 7.5 cm x 5.0 cm. The pectoralis major myocutaneous flaps (14.0 cm x 3.5 cm to 17.0 cm x 5.5 cm) were incised at the level of the 3rd to the 4th rib, and then split down along the muscle fiber till about 2 cm away from the thoracoacromial vessels, forming 2 independent skin paddles with 1-2 branch vessels to the pedicles of the distal ones. The distal skin paddles were used for oral reconstruction while the proximal paddles for repair of neck defects. The chest donor sites were sutured directly. Cervical haematoma and infection happened in 1 patient respectively after operation, and were cured after symptomatic treatment. All 6 split pectoralis major myocutaneous flaps with 12 skin paddles completely survived. All patients were followed up 6 to 18 months (mean, 11 months). One patient died of pulmonary metastasis at 8 months after operation and the other 5 survived without relapse or metastasis during follow-up. The intraoral paddles showed good shape with satisfactory speech function and swallowing recovery. The paddles also healed perfectly on the neck with flat outlooks, and all patients obtained full

Over the last 20 years, there has been increasing awareness of a subset of squamous cell carcinomas of the head and neck (HNSCC), i.e. HPV-positive HNSCC. These cancers seem to differ somewhat from HPV-negative HNSCC. Patients with HPV-positive HNSCC tend to be younger and have a lower intake of ......-negative HNSCC, and this seems to be related to the immune system. Whether the new vaccines for HPV will protect not only against cervical cancer but also against HPV-positive HNSCC remains unknown....

Metastases to regional lymph nodes of the neck in patients with larynx cancer are a more frequent cause of death in comparison to local recurrence. Thus it is necessary to thoroughly examine the treatment and after the treatment. The ultrasound examination introduced significant diagnostic value in the diagnosis of malignant cancers. Ultrasound monitoring of the lymphatic system after surgical treatment or radiation allows to diagnose early metastases which are not visible in palpation examination. In over 200 patients after surgical treatment of larynx cancer several ultrasound examinations of the neck were carried out. The time following the end of the treatment was 4 months to l 8 years. In the ultrasound examination of the neck changes in the lymphatic system were observed, which were not clinically manifested in 10 patients. Metastases to regional lymph nodes of the neck were most frequently observed in the first year after the operation. Patients who were diagnosed with metastases before operation and patients with supraglottic cancers were at more risk of having metastases. The ultrasound examination of the neck should be a routine, systematically repeated examination in the observation of patients after larynx cancer operation. (author)

Preoperative lymph node screening of all neck compartments is favored by clinicians for the management of the neck. The presence of a metastatic node on one side of the neck reduces the 5-year survival rate to 50%, and the presence of a metastatic node on both sides of the neck reduces the 5-year survival rate to 25%. This study compared the evaluation of lymph node metastases by ultrasonography (USG) and computed tomography (CT) in patients with squamous cell cancer of the head and neck region. Five hundred and eighty-four patients with squamous cell cancer of the head and neck were prospectively evaluated for the presence of cervical lymph node metastases. All patients underwent clinical examination (palpation), USG and CT imaging. Neck dissection was performed in all the patients, and the results of the preoperative evaluation were correlated with the surgical and histopathological findings. Metastases in neck nodes were identified in 148 patients by histopathological examination. Doppler USG correctly identified 136 node-positive patients (n=148; sensitivity 91.8%, specificity 97%). CT imaging correctly identified 122 patients with metastatic lymph nodes (n=148; sensitivity 83%, specificity 93%). Positive predictive values of USG and CT imaging were 95.6% and 91.3%, respectively, whereas the negative predictive values of these two imaging studies were 95.4% and 89.6%, respectively. The accuracy and sensitivity of USG in detection of cervical lymph node metastases make it a potentially promising and cheap preoperative tool for staging neck node metastases and optimizing the treatment plan for surgeons, especially in countries such as India.

Purpose: To compare the patterns of care for elderly head-and-neck cancer patients with those of younger patients. Methods and Materials: A retrospective review was conducted of all new mucosal head-and-neck cancer referrals to radiation oncology between July 1, 2003 and December 31, 2007 at our institution. The clinical characteristics, treatment pattern, tolerance, and outcomes were compared between the elderly (aged ≥75 years) and younger (aged <75 years) cohorts. Results: A total of 2,312 patients, including 452 (20%) elderly and 1,860 (80%) younger patients, were studied. The elderly patients were more likely to be women (36% vs. 27%, p <.01) and to have other malignancies (23% vs. 13%, p <.01), Stage I or II disease (38% vs. 32%, p <.01), and N0 status (56% vs. 42%, p <.01). Treatment was less often curative in intent (79% vs. 93%, p <.01). For the 1,487 patients who received definitive radiotherapy (RT), no differences were found between the elderly (n = 238) and younger (n = 1,249) patients in treatment interruption, completion, or treatment-related death. Within the subset of 760 patients who received intensified treatment (concurrent chemoradiotherapy or hyperfractionated accelerated RT), no difference was seen between the elderly (n = 46) and younger (n = 714) patients in treatment interruption, completion, or treatment-related death. After a median follow-up of 2.5 years, the 2-year cause-specific survival rate after definitive RT was 72% (range, 65-78%) for the elderly vs. 86% (range, 84-88%) for the younger patients (p <.01). Conclusion: Elderly head-and-neck cancer patients exhibited different clinical characteristics and experienced different patterns of care from younger patients. Although age itself was an adverse predictor of cause-specific survival, its effect was modest. Elderly patients selected for definitive RT or intensified RT showed no evidence of impaired treatment tolerance.

Full Text Available Abstract Background This study evaluated the feasibility, toxicity, response rate and survival of neoadjuvant superselective intra-arterial infusion of high dose carboplatin in advanced head and neck cancer. Methods Forty-six patients with primary head and neck squamous cell carcinoma received 3 cycles of intra-arterial carboplatin (300 to 350 mg/m2 per cycle every 2 weeks, followed by radiotherapy or surgery plus radiotherapy. Results No complications or severe toxicity occurred. Sixteen patients (35% were complete responders, 20 (43% partial responders while 10 (22% did not respond to treatment. After completion of the multimodality treatment, 38/46 patients (83% were complete responders. After a 5-year follow-up period, 18/46 patients (39% are alive and disease-free, 3 (6,5% have died of a second primary tumor and 25 (54,5% have died of the disease. Conclusion Intra-arterial carboplatin induction chemotherapy is a safe, well-tolerated technique that discriminates between responders and non-responders and so may have prognostic significance in planning further integrated treatments aimed to organ preservation for advanced head and neck carcinomas.

Background: Tumor hypoxia has proven prognostic impact in head and neck cancers and is associated with poor response to radiotherapy. Hyperbaric oxygenation (HBO) offers an approach to overcome hypoxia. We have performed pO 2 measurements in selected patients with head and neck cancers under HBO to determine in how far changes in the oxygenation occur and whether a possible improvement of oxygenation parameters is maintained after HBO. Patients and Methods: Seven patients (five male, two female, age 51-63 years) with squamous cell cancers of the head and neck were investigated (six primaries, one local recurrence). The median pO 2 prior to HBO was determined with the Eppendorf histograph. Sites of measurement were enlarged cervical lymph nodes (n = 5), the primary tumor (n = 1) and local recurrence (n = 1). Patients then underwent HBO (100% O 2 at 240 kPa for 30 minutes) and the continuous changes in the oxygenation during HBO were determined with a Licox probe. Patients had HBO for 30 minutes (n = 6) to 40 minutes (n = 1). HBO was continued because the pO 2 had not reached a steady state after 30 minutes. After decompression, patients ventilated pure oxygen under normobaric conditions and the course of the pO 2 was further measured over about 15 minutes. Results: Prior to HBO, the median tumor pO 2 in the Eppendorf histography was 8.6 ± 5.4 mm Hg (range 3-19 mm Hg) and the pO 2 measured with the Licox probe was 17.3 ± 25.5 mm Hg (range 0-73 mm Hg). The pO 2 increased significantly during HBO to 550 ± 333 mm Hg (range 85-984 mm Hg, p = 0.018). All patients showed a marked increase irrespective of the oxygenation prior to HBO. The maximum pO 2 in the tumor was reached after 10-33 minutes (mean 17 minutes). After leaving the hyperbaric chamber, the pO 2 was 282 ± 196 mm Hg. All patients maintained an elevated pO 2 for further 5-25 minutes (138 ± 128 mm Hg, range 42-334 mm Hg, p = 0.028 vs the pO 2 prior to HBO). Conclusions: Hyperbaric oxygenation resulted in a

We examined the association of ABO blood groups with the different types of head and neck cancers. 195 diagnosed cases and 801 controls were selected from a Greek tertiary cancer center. Information regarding type of head and neck cancer and ABO blood group was collected and registered. The O blood group was found to be most prevalent followed by A, B and AB among the controls, whereas blood group A followed by O, B and AB was most prevalent among cancer patients. The difference among the distribution between the cases and controls was statistically significant in blood group A (pblood group A had 1.52-fold higher risk of developing head and neck cancer compared to people of other blood groups. Blood group A was found to be a potential risk factor for the development of head and neck cancers.

Purpose: The role of neck dissection after definitive radiation for head-and-neck cancer is controversial. We select patients for neck dissection based on postradiation therapy (post-RT), computed tomography (CT), and [ 18 F] fluorodeoxyglucose positron emission tomography (FDG PET). We summarize the clinical outcomes of patients treated with this policy to further elucidate the role of FDG PET in decision making for neck dissection after primary radiotherapy. Methods and Materials: Between December 1999 and February 2004, 53 eligible patients were identified. These patients had stage N2A or higher head-and-neck squamous cell carcinoma and had complete response of the primary tumor after definitive radiation with or without chemotherapy. PET or computed tomography (CT) scans were performed within 6 months after treatment. Neck dissection was performed in patients with residual lymphadenopathy (identified by clinical examination or CT) and a positive PET scan. Those without residual lymph nodes and a negative PET were observed without neck dissection. For patients with residual lymphadenopathy, but a negative PET scan, neck dissection was performed at the discretion of the attending surgeon and decision of the patient. There was a total of 70 heminecks available for analysis (17 patients had bilateral neck disease). Results: There were 21 heminecks with residual lymphadenopathy identified on CT imaging or clinical examination and negative PET. Of these, 4 had neck dissection and were pathologically negative. The remaining 17 were observed without neck dissection. There was a total of 42 heminecks without residual lymph nodes on post-RT CT imaging or clinical examination with a negative PET. They were also observed without neck dissection. Seven heminecks had a positive PET scan and residual lymphadenopathy. Six of them had neck dissection and 1 had fine-needle aspiration of a residual node; 3 contained residual viable cancer and 4 were pathologically negative. At

Purpose: Intravenous amifostine 200 mg/m 2 reduces xerostomia in head-and-neck cancer patients. This Phase II study evaluated subcutaneous (s.c.) amifostine in a similar patient population. Patients and Methods: Patients received amifostine 500 mg, administered as two 250-mg s.c. injections 60 min before once-daily radiation for head-and-neck cancer (50-70 Gy in 5-7 weeks). The primary endpoint was the incidence of ≥Grade 2 acute xerostomia. Results: Fifty-four patients received s.c. amifostine and radiotherapy. The incidence of ≥Grade 2 acute xerostomia was 56% (95% CI, 43-69%) and the incidence of ≥Grade 2 late xerostomia at 1 year was 45% (95% CI, 29-61%). The incidence of acute xerostomia was lower than reported previously with no amifostine in a controlled study; rates of acute xerostomia were similar between s.c. and i.v. amifostine in the two studies. The rate of late xerostomia with s.c. amifostine was intermediate between rates for i.v. amifostine and no amifostine, and not statistically significantly different from either historical control. Grades 1-2 nausea and emesis were the most common amifostine-related adverse events. Grade 3 amifostine-related adverse events reported by >1 patient included: dehydration (11%); rash (6%); and weight decrease, mucositis, dyspnea, and allergic reaction (each 4%). Seven patients (13%) had serious cutaneous adverse events outside the injection site. One-year rates of locoregional control, progression-free survival, and overall survival were 78%, 75%, and 85%, respectively. Conclusions: Subcutaneous amifostine provides a well-tolerated yet simpler alternative to i.v. amifostine for reducing acute xerostomia in head-and-neck cancer patients

DNA repair genes play critical roles in response to carcinogen-induced and anticancer therapy-induced DNA damage. Benzo[a]pyrene (BaP), the most carcinogenic polycyclic aromatic hydrocarbon (PAH), is classified as a group 1 carcinogen by International Agency for Research on Cancer. The aims of this study were to (1) evaluate the effects of BaP on DNA repair activity and expression of DNA repair genes in vitro and (2) examine the role of xeroderma pigmentosum, complementation group D (XPD) mRNA expression in human head and neck cancers. Host cell reactivation assay showed that BaP inhibited nucleotide excision repair in H1299 lung cancer cells. DNA repair through the non-homologous end-joining pathway was not affected by BaP. Real-time quantitative reverse-transcription polymerase chain reaction (RT-PCR) and Western blot demonstrated that XPD was downregulated by BaP treatment. BaP exposure did not apparently affect expression of another 11 DNA repair genes. BaP treatment increased the DNA damage marker γ-H2AX and ultraviolet (UV) sensitivity, supporting an impairment of DNA repair in BaP-treated cells. XPD expression was also examined by quantitative RT-PCR in 68 head and neck cancers, and a lower XPD mRNA level was found in smokers' cancer specimens. Importantly, reduced XPD expression was correlated with patient 5-year overall survival rate (35 vs. 56%) and was an independent prognostic factor (hazard ratio: 2.27). Data demonstrated that XPD downregulation was correlated with BaP exposure and human head and neck cancer survival.

Background and purpose: Post-operative radiotherapy is indicated for the treatment of head and neck cancers. In vitro, chemotherapy potentiates the cytotoxic effects of radiation. We report the results of a randomized trial testing post-operative radiotherapy alone versus concomitant carboplatin and radiotherapy for head and neck cancers with lymph node involvement. Materials and methods: The study involved patients undergoing curative-intent surgery for head and neck cancers with histological evidence of lymph node involvement. Patients were randomly assigned to receive radiotherapy alone (54-72 Gy, 30-40 fractions, 6-8 weeks) or identical treatment plus concomitant Carboplatin (50 mg/m 2 administered by IV infusion twice weekly). Results: Between February 1994 and June 2002, 144 patients were included. With a median follow-up of 106 months (95% confidence interval (CI) [92-119]), the 2-year rate of loco-regional control was 73% (95% CI: 0.61-0.84) in the combined treatment group and 68% (95% CI: 0.57-0.80) in the radiotherapy group (p = 0.26). Overall survival did not differ significantly between groups (hazard ratio for death, 1.05; 95% CI: 0.69-1.60; p = 0.81). Conclusions: Twice-weekly administration of carboplatin concomitant to post-operative radiotherapy did not improve local control or overall survival rates in this population of patients with node-positive head and neck cancers

Purpose: We previously demonstrated the efficacy of concurrent gemcitabine, paclitaxel, and 5-fluorouracil in conjunction with twice-daily (1.5-Gy) radiotherapy delivered on alternating weeks (TFGX 2 ) in locally advanced head-and-neck cancer. Here, we report the clinical outcome and late toxicity of TFGX 2 in a subset of patients previously irradiated to the head and neck. Methods and materials: Twenty-nine previously irradiated patients, presenting with recurrent or second primary head-and-neck cancer, underwent TFGX 2 . Twelve patients underwent attempted surgical resection before chemoradiotherapy, 10 of whom were left with no measurable disease. Patients with measurable disease received a median radiation dose of 72 Gy; those with no measurable disease received a median dose of 61 Gy. The cumulative dose ranged from 74.4 to 156.4 Gy (mean, 125.7 Gy; median, 131.0 Gy). Results: The median follow-up was 19.1 months (50.9 months for living patients). The 5-year overall survival rate was 34.5%, and the locoregional control rate was 54.5%. In patients with measurable disease at treatment, the 5-year overall survival and locoregional control rate was 26.3% and 45.1%, respectively, compared with 50.0% (p = 0.14) and 70% (p = 0.31), respectively, for those with no measurable disease. Measurable disease and radiation dose were highly statistically significant for overall survival and locoregional control on multivariate analysis. Of 14 patients assessable for late toxicity, 3 developed Grade 4-5, 8 Grade 2-3, and 3 Grade 0-1 toxicity. Conclusion: Aggressive reirradiation with chemotherapy in locally advanced head-and-neck cancer provides a chance for long-term cure at the expense of toxicity. Attempted surgical resection before chemoradiotherapy improved disease control and survival

The National Quality Forum has endorsed quality-improvement measures for multiple cancer types that are being developed into actionable tools to improve cancer care. No nationally endorsed quality metrics currently exist for head and neck cancer. The authors identified patients with surgically treated, invasive, head and neck squamous cell carcinoma in the National Cancer Data Base from 2004 to 2014 and compared the rate of adherence to 5 different quality metrics and whether compliance with these quality metrics impacted overall survival. The metrics examined included negative surgical margins, neck dissection lymph node (LN) yield ≥ 18, appropriate adjuvant radiation, appropriate adjuvant chemoradiation, adjuvant therapy within 6 weeks, as well as overall quality. In total, 76,853 eligible patients were identified. There was substantial variability in patient-level adherence, which was 80% for negative surgical margins, 73.1% for neck dissection LN yield, 69% for adjuvant radiation, 42.6% for adjuvant chemoradiation, and 44.5% for adjuvant therapy within 6 weeks. Risk-adjusted Cox proportional-hazard models indicated that all metrics were associated with a reduced risk of death: negative margins (hazard ratio [HR] 0.73; 95% confidence interval [CI], 0.71-0.76), LN yield ≥ 18 (HR, 0.93; 95% CI, 0.89-0.96), adjuvant radiation (HR, 0.67; 95% CI, 0.64-0.70), adjuvant chemoradiation (HR, 0.84; 95% CI, 0.79-0.88), and adjuvant therapy ≤6 weeks (HR, 0.92; 95% CI, 0.89-0.96). Patients who received high-quality care had a 19% reduced adjusted hazard of mortality (HR, 0.81; 95% CI, 0.79-0.83). Five head and neck cancer quality metrics were identified that have substantial variability in adherence and meaningfully impact overall survival. These metrics are appropriate candidates for national adoption. Cancer 2017;123:4372-81. © 2017 American Cancer Society. © 2017 American Cancer Society.

Objective: To investigate the prevalence and psychosocial characteristics in inpatients with head and neck cancer before surgery. Method: From September 2015 to December 2016, 237 consecutive inpatients with head and neck cancer who had been scheduled for surgery were prospectively enrolled in Department of Head and Neck Surgery of Shanxi Provincial Tumor Hospital. Mental health symptoms were systematically investigated using three psychological instruments: symptom checklist-90 (SCL-90), Zung self-rating anxiety scale (SAS) and Zung self-rating depression scale (SDS). SPSS 17.0 software was used to analyze the data. And he results of SCL-90, SAS and SDS were compared with the Chinese norm. For all statistical analyses, a P value psychological status in inpatients with head and neck cancer before surgery. Identifying these patients using proper screening instrument is of great important clinical implications for the early detection, management, and reduction of the distress associated with head and neck cancer.

Seven cases of delayed airway stenosis after radiotherapy for early staged head and neck cancers during 1989 and 1999 were evaluated (aged 54-77 yrs, 6 male and a female). The cases included five glottic laryngeal cancers (T1a, T1b, and three T2), a subglottic laryngeal cancer, and an unknown origin, but strongly suspected laryngeal cancer, with neck metastasis. Radio injury was found from 3 months to 47 months after radiotherapy. {sup 60}Co for radiotherapy was used in all seven cases, although {sup 60}Co radionuclide was changed to Liniac in 1997. The total dose was 60 Gy for 3 cases, and 70 Gy for 4 cases. Tracheostomy was performed in 3 cases due to bilateral vocal cord impairment. Background, treatment, and response to radiotherapy were compared to those of 90 patients of a control group with early staged laryngeal cancer who did not fail radiation injury during the same period. As a result, radionuclide ({sup 60}Co), total dose, cervical surgery, antiinflammatory drugs, laryngeal edema during radiotherapy were risk factors. The intensity and the period of mucositis by radiotherapy was important for indicating delayed airway stenosis. (author)

Head and neck cancer patients treated with surgery often experience significant postoperative morbidities. Administering preoperative nutritional intervention may improve surgical outcomes, but there is currently a paucity of data reviewing the association between preoperative nutritional status and postoperative outcome. It is therefore of importance to investigate this association among head and neck cancer patients. To assess the association between preoperative nutritional status and postoperative outcome in head and neck cancer patients treated with surgery, a retrospective study of 70 head and neck cancer patients who were surgically treated between 2013 and 2014 in a tertiary referral head and neck surgery center in Hong Kong was conducted. Clinical data regarding preoperative nutritional status and postoperative outcome were retrieved from a computer record system. Logistic and linear regressions were used to analyze the appropriate parameters. A higher preoperative albumin level was associated with lower rates of postoperative complications and better wound healing (P cancer patients, preoperative intervention strategies that boost albumin levels could be considered for improving surgical outcome.

1995-06-15

Purpose: To retrospectively assess a protocol of split-course accelerated radiation therapy (SCAT) for selected head and neck cancers. Methods and Materials: SCAT consisted of 1.8 Gy per fraction administered twice daily with a minimum gap between fractions of 6 h. The treatment protocol prescribed an initial 16 fractions followed by a planned 5 to 12 day break, and then a further 20 to 22 fractions for a total dose ranging from 64.8 to 72 Gy delivered in 5 to 6 weeks. Results: Twenty-eight patients received SCAT for histologically confirmed head and neck cancer between January 1987 and August 1991. All patients were followed up until December 1, 1993. The mean potential follow-up time was 4.2 years (range: 2.9-6.2 years). All patients completed the treatment protocol. Thirteen tumors were laryngeal in origin, eight hypopharyngeal, four paranasal sinus, and three oropharyngeal. There were no Stage I, three Stage II, nine Stage III, and 12 Stage IV tumors. Four tumors were not staged (two paranasal sinus cancers and two surgical recurrences). Early and late toxicities were moderate to severe. Confluent mucositis was experienced by 27 of the 28 patients (96%). One patient required a prolonged midtreatment break of 24 days. Nine patients (32%) required narcotic analgesia for pain relief. Eleven patients (39%) required hospitalization for nasogastric feeding or pain control. The median length of hospital stay was 14 days (range 7-98 days). The actuarial rate of severe late toxicity at 3 years was 47% (standard error (SE) = 13%). A complete tumor response was achieved in 86% of patients. The actuarial local control rate at 3 years was 43% (SE = 11%) and the actuarial survival rate at 3 years was 25% (SE = 8%). Conclusion: Given the encouraging complete response rate and local control for such advanced tumors, SCAT for locoregionally advanced tumors merits further investigation. However, because of the significant late toxicity observed, the total dose, interfraction

Purpose/Objective: The role of chemotherapy in the management of squamous cell carcinoma of the upper aerodigestive tract is undergoing rapid evolution. Historically, the use of chemotherapy was limited to patients with incurable disease who had exhausted all surgical and radiation therapy options. The results of recent randomized trials, however, suggest an increasing role for chemotherapy as part of primary management in patients with unresectable disease; advanced larynx or hypopharynx cancer with the intent of larynx preservation, or advanced nasopharynx cancer. This refresher course will provide a comprehensive overview of the current indications for chemotherapy in the management of these malignancies, and will highlight areas of controversy and future directions of investigation. More specifically, the following areas will be emphasized. 1. The identification of drugs commonly used in the management of head and neck cancer, their customary dosing and side effects. 2. The impact of induction and/or adjuvant chemotherapy combined with surgery and radiation therapy as defined by randomized trials, including a discussion of the Head and Neck Contracts program and the Intergroup adjuvant trial. 3. The development of larynx/function preservation treatment programs, including a review of the Veterans Administration and EORTC larynx preservation studies. 4. The evolving role of chemotherapy as part of innovative combined modality programs, especially in patients with unresectable disease. The rationale and utility of sequential versus concomitant/alternating chemotherapy-radiation strategies, and relevant randomized clinical trials comparing the different strategies will be discussed. 5. The appropriate application of chemotherapy in the palliative setting, including a discussion of the relative merits of single-agent versus combination chemotherapy

Background and purpose: We would like to assess the prevalence of aspiration before and following chemoradiation for head and neck cancer. Patients and methods: We reviewed retrospectively the Modified Barium Swallow (MBS) in 63 patients who underwent concurrent chemotherapy and radiation for head and neck cancer. MBS was performed prior to treatment to determine the need for immediate gastrostomy tube placement. MBS was repeated following treatment to assess the safety of oral feeding prior to removal of tube feeding. All patients were cancer free at the time of the swallowing study. No patient had surgery. Dysphagia severity was graded on a scale of 1-7. Tube feedings were continued if patients were diagnosed to have severe aspiration (grade 6-7) or continued weight loss. Patients with abnormal swallow (grade 3-7) received swallowing therapy following MBS. Results: Before treatment, there were 18 grade 1, 18 grade 2, 9 grade 3, 8 grade 4, 3 grade 5, 3 grade 6, and 4 grade 7. Following chemoradiation, at a median follow-up of 2 months (1-10 months), one patient had grade 1, eight patients had grade 2, nine patients had grade 3, eight patients had grade 4, 13 patients had grade 5, seven patients had grade 6, and 11 patients had grade 7. Six patients died from aspiration pneumonia (one before, three during, and two post-treatment), and did not have the second MBS. Overall, 37/63 (59%) patients developed aspiration, six of them (9%) fatal. If we excluded the 10 patients who had severe aspiration at diagnosis and the six patients who died from pneumonia, the prevalence of severe aspiration was 33% (21/63). Conclusions: Aspiration remained a significant morbidity following chemoradiation for head and neck cancer. Its prevalence is underreported in the literature because of its often silent nature. Diagnostic studies such as MBS should be part of future head and neck cancer prospective studies to assess the prevalence of aspiration, and for rehabilitation

We investigated the safety and efficacy of alternative and concurrent chemoradiotherapy with 5-fluorouracil (FU)/nedaplatin (CDGP) for head and neck cancer. From January 2003 to August 2005, 19 patients with head and neck squamous cell carcinoma were treated in our institution. Alternative chemoradiotherapy (ACRT) was performed for 8 cases of nasopharyngeal cancer. Concurrent chemoradiotherapy (CCRT) was performed for 11 cases of other head and neck cancer. Median total dose of radiotherapy was 63 Gy. ACRT consisted of 5-FU at a dose of 500 mg/m 2 on days 1-5 and 28-32 and CDGP at a dose of 60 mg/m 2 on days 6 and 33. CCRT consisted of 5-FU at a dose of 500 mg/m 2 on days 1-4 and 28-31 and CDGP at a dose of 60 mg/m 2 on days 5 and 32. Median follow-up period was 13 months. CR+PR was admitted in five cases (63%) with ACRT, and in 9 cases (82%) with CCRT. Non-hematological adverse effects of grade 3 were admitted in eight cases (100%) of ACRT, and in 9 cases (82%) of CCRT. Chemoradiotherapy attained good results and non-hematological adverse effects were able to be managed by preserved treatment. (author)

Postoperative delirium is common after extensive surgery. This study aimed to collate and synthesize published literature on risk factors for delirium in patients with head and neck cancer surgery. Three databases were searched (MEDLINE, Embase, and Cochrane Library) between January 1987 and July 2016. The Newcastle Ottawa Scale (NOS) was adopted to evaluate the study quality. Pooled odds ratios or mean differences for individual risk factors were estimated using the Mantel-Haenszel and inverse-variance methods. They provided a total of 1940 patients (286 with delirium and 1654 without), and predominantly included patients undergoing head and neck cancer surgery. The incidence of postoperative delirium ranged from 11.50% to 36.11%. Ten statistically significant risk factors were identified in pooled analysis. Old age, age >70 years, male sex, duration of surgery, history of hypertension, blood transfusions, tracheotomy, American Society of Anesthesiologists physical status grade at least III, flap reconstruction and neck dissection were more likely to sustain delirium after head and neck cancer surgery. Delirium is common in patients undergoing major head neck cancer surgery. Several risk factors were consistently associated with postoperative delirium. These factors help to highlight patients at risk of developing delirium and are suitable for preventive action. © The Author 2017. Published by Oxford University Press. All rights reserved.

Purpose: To assess the benefit of intensity-modulated radiotherapy (IMRT) compared with conventional RT for the quality of life (QOL) of head and neck cancer survivors. Methods and Materials: Cross-sectional QOL measures (European Organization for Research and Treatment of Cancer QOL questionnaire C30 and head and neck cancer module) were used with a French multicenter cohort of patients cured of head and neck cancer (follow-up ≥ 1 year) who had received bilateral neck RT (≥ 45 Gy) as a part of their initial treatment. We compared the QOL mean scores regarding RT modality (conventional RT vs. IMRT). The patients of the two groups were matched (one to one) according to the delay between the end of RT and the timing of the QOL evaluation and the T stage. Each QOL item was divided into two relevant levels of severity: 'not severe' (responses, 'not at all' and 'a little') vs. 'severe' (responses 'quite a bit' and 'very much'). The association between the type of RT and the prevalence of severe symptoms was approximated, through multivariate analysis using the prevalence odds ratio. Results: Two comparable groups (67 pairs) were available. Better scores were observed on the head and neck cancer module QOL questionnaire for the IMRT group, especially for dry mouth and sticky saliva (p < 0.0001). Severe symptoms were more frequent with conventional RT concerning saliva modifications and oral discomfort. The adjusted prevalence odds ratios were 3.17 (p = 0.04) for dry mouth, 3.16 (p = 0.02) for sticky saliva, 3.58 (p = 0.02) for pain in the mouth, 3.35 (p = 0.04) for pain in the jaw, 2.60 (p = 0.02) for difficulties opening the mouth, 2.76 (p = 0.02) for difficulties with swallowing, and 2.68 (p = 0.03) for trouble with eating. Conclusion: The QOL assessment of head and neck cancer survivors demonstrated the benefit of IMRT, particularly in the areas of salivary dysfunction and oral discomfort

Head and neck cancers are associated with high rates of depression, which may increase the risk for poorer immediate and long-term outcomes. Here it was hypothesized that greater depressive symptoms would predict earlier mortality, and behavioral (treatment interruption) and biological (treatment response) mediators were examined. Patients (n = 134) reported depressive symptomatology at treatment planning. Clinical data were reviewed at the 2-year follow-up. Greater depressive symptoms were associated with significantly shorter survival (hazard ratio, 0.868; 95% confidence interval [CI], 0.819-0.921; P ratio, 0.865; 95% CI, 0.774-0.966; P = .010), and poorer treatment response (odds ratio, 0.879; 95% CI, 0.803-0.963; P = .005). The poorer treatment response partially explained the depression-survival relation. Other known prognostic indicators did not challenge these results. Depressive symptoms at the time of treatment planning predict overall 2-year mortality. Effects are partly influenced by the treatment response. Depression screening and intervention may be beneficial. Future studies should examine parallel biological pathways linking depression to cancer survival, including endocrine disruption and inflammation.

Fractionation schedules for cancers of the head and neck

International Nuclear Information System (INIS)

Harari, Paul M.

1995-01-01

Purpose/Objective: This refresher course reviews current research activity and treatment results in the field of radiation therapy fractionation. The presentation emphasizes worldwide studies of altered fractionation, highlighting head and neck cancer as the primary teaching model. Basic radiobiological principles guiding the development of altered fractionation regimens, and advancing the understanding of fractionation effects on normal and tumor tissue are reviewed. A 'standard' prescription of 2 Gy x 35 fractions = 70 Gy may not provide the optimal balance between primary tumor control and late normal tissue effects for all patients with squamous cell carcinoma of the head and neck. The last decade has witnessed the treatment of thousands of head and neck cancer patients with curative radiotherapy using altered fractination schedules designed to improve overall treatment results. Although the number of different fractionation regimens currently being investigated continues to increase, the common guiding principles behind their design are relatively simple. Common fractionation terminology (i.e., accelerated hyperfractionation) will be reviewed, as well as a brief summary of radiobiological concepts pertaining to tumor potential doubling time, tumor proliferation kinetics, overall treatment time and fraction size-dependence of acute and late tissue effects. Several well known head and neck fractionation schedules from around the world (Manchester Christie Hospital-United Kingdom, Princess Margaret Hospital-Canada, Massachusetts General Hospital-USA, MD Anderson Hospital-USA, University of Florida-USA, Mount Vernon Hospital CHART-United Kingdom, RTOG and EORTC trials-USA and Europe) will be summarized with regard to design-rationale, treatment technique and results. The design of several current cooperative group trials investigating altered head and neck fractionation will be presented, as well as concepts prompting the pilot evaluation of several brand new

Sexually transmitted oral cancer/head and neck cancer is increasing rapidly. Human papilloma virus (HPV) is playing a role in the pathogenesis of a subset of squamous cell carcinoma of head and neck (SCCHN). Paclitaxel is a widely used anticancer drug for breast, ovarian, testicular, cervical, non-small cell lung, head and neck cancer. However, it is water insoluble and orally inactive. We report the synthesis of water soluble nanosize conjugates of paclitaxel, branched PEG, and EGFR-targeting peptide by employing native chemical ligation. We performed a native chemical ligation between the N-hydroxy succinimide (NHS) ester of paclitaxel succinate and cysteine at pH 6.5 to give the cysteine-conjugated paclitaxel derivative. The thiol functionality of cysteine was activated and subsequently conjugated to multiarm thiol-PEG to obtain the paclitaxel branched PEG conjugate. Finally, we conjugated an EGFR-targeting peptide to obtain conjugates of paclitaxel, branched PEG, and EGFR-targeting peptide. These conjugates show anticancer activity against squamous cell carcinoma of head and neck cells (SCCHN, Tu212).

The purpose of this study was to examine the relationship between physical impairments, quality of life and disability in patients following neck dissection, with consideration of patient and clinical characteristics. Cross-sectional study of patients < 5 years after neck dissection for head and neck cancer. Quality of life and self-reported disability were measured with the Neck Dissection Impairment Index, Quick Disabilities of the Arm, Shoulder and Hand, and Neck Disability Index. Active neck and shoulder range of motion and isometric muscle strength were also assessed. Generalised linear modelling was used to explore relationships between variables. Eighty-four participants (68% male, median age 61 years) demonstrated reduced quality of life (median (interquartile range) score = 76 (49, 93) from 0 (worst) to 100 (best)), and mild levels of upper limb (14 (2, 32)) and neck disability (14 (6, 28)) (from 0 (best) to 100 (worst)). Bilateral neck dissection was associated with reduced quality of life (coeff (95% CI) = - 12.49 (- 24.69, - 0.29)). Post-operative chemoradiation therapy was associated with reduced quality of life (- 21.46 (- 37.57, - 5.35)) and neck disability (0.71 (0.10, 1.32)). Measures of shoulder flexibility or strength were associated with quality of life and self-reported disability. Quality of life and musculoskeletal disability after neck dissection are associated with factors from multiple domains including physical motor function and treatment modality. Having reduced shoulder flexibility or strength is related to functional deficits and quality of life after neck dissection for head and neck cancer.

Objective: The purpose of the study is to evaluate dysphagia severity following chemoradiation and postoperative radiation for head and neck cancer, and particularly the aspiration risk because of its potential life-threatening consequence. Materials and methods: We reviewed retrospectively the modified barium swallow (MBS) results in 110 patients who complained of dysphagia following chemoradiation (57) and postoperative radiation (53) of their head and neck cancer. Patients were selected if they were cancer free at the time of the swallowing study. Dysphagia severity was graded on a scale of 1-7. Patients were grouped according to the dysphagia severity: mild (grades 2-3), moderate (grades 4-5), and severe (grades 6-7). Results: Mean and median dysphagia grades were 4.84/5 and 4.12/4 for chemoradiation and postoperative radiation respectively. The mean difference between the two groups is statistically significant (p = 0.02). Mild dysphagia occurred in 13 patients (22%) of the chemoradiation group and 17 (32%) of the postoperative group. Corresponding number for the moderate group was 25 (43%) and 25 (48%), respectively. Severe dysphagia was significant in the chemoradiation group (34%) compared to the postoperative group (19%). However, the difference was not statistically significant (p = 0.29). There was a higher proportion of patients with large tumor (T3-T4) in the chemoradiation group who developed severe dysphagia. Conclusion: Dysphagia remained a significant morbidity of chemoradiation and postoperative radiation for head and neck cancer. Dysphagia may be more severe in the chemoradiation group because of the higher proportion of patients with large tumor, the high radiation dose, and a high number of oropharyngeal tumors. Aspiration occurred in both groups. Diagnostic studies such as MBS should be part of future head and neck cancer prospective studies to assess the prevalence of aspiration, as it may be silent.

To determine the prevalence and profile of patients who use complementary and alternative medicine, within a cohort of head and neck cancer patients. Cross-sectional survey. Ninety-three consecutive head and neck cancer patients being followed up at the department of otolaryngology head and neck surgery were surveyed using an interviewer-administered questionnaire. The prevalence of complementary and alternative medicine use was 67.8 per cent. Patients who used complementary and alternative medicine were more likely to be female, better educated and younger, compared with non-users. A total of 82.5 per cent (52/63) perceived complementary and alternative medicine to be effective, even though they were aware of the lack of research and endorsement by their physician regarding such medicine. The use of complementary and alternative medicine by head and neck cancer patients is common, regardless of efficacy or cost. Clinicians should routinely ask patients about their use of complementary and alternative medicine, to facilitate communication and enable appropriate use of such medicine.

This study is to determine the impact of virus in surgical outcomes among patients of head and neck cancer with N3 lymph node metastasis. A retrospective analysis was conducted for 32 patients with operable N3 neck metastasis undergoing surgical treatment between January 1987 and October 2006. The nuclei of the tumor cells were investigated for the presence of human papillomavirus (HPV) and Epstein-Barr virus (EBV) DNAs and were taken into account as the variable for survival analysis. The primary sites were oropharynx in 11 patients, tongue in 3, buccal mucosa in 1, hypopharynx in 8 and unknown primary in 9. The five-year cumulative overall survival rate was 40.7% and 5-year cumulative regional control rate was 55.8%. The 5-year cumulative overall survival rate of patients with unknown primary site (72.9%) and HPV or EBV positive in the tumor (77.8%) were significantly higher than those patients with known primary site (31.3%) and HPV or EBV negative in the tumor (27.4%), respectively (P = 0.0335 and P = 0.0348, log rank test). In conclusion, surgery with adjuvant therapy offers reasonable outcomes for operable N3 node in head and neck cancer in our cohort. In addition, patients with HPV or EBV positive in the tumor have a better survival.

Purpose: To identify clinical and treatment-related predictors of brachial plexus–associated neuropathies after radiation therapy for head-and-neck cancer. Methods and Materials: Three hundred thirty patients who had previously completed radiation therapy for head-and-neck cancer were prospectively screened using a standardized instrument for symptoms of neuropathy thought to be related to brachial plexus injury. All patients were disease-free at the time of screening. The median time from completion of radiation therapy was 56 months (range, 6–135 months). One-hundred fifty-five patients (47%) were treated by definitive radiation therapy, and 175 (53%) were treated postoperatively. Radiation doses ranged from 50 to 74 Gy (median, 66 Gy). Intensity-modulated radiation therapy was used in 62% of cases, and 133 patients (40%) received concurrent chemotherapy. Results: Forty patients (12%) reported neuropathic symptoms, with the most common being ipsilateral pain (50%), numbness/tingling (40%), motor weakness, and/or muscle atrophy (25%). When patients with <5 years of follow-up were excluded, the rate of positive symptoms increased to 22%. On univariate analysis, the following factors were significantly associated with brachial plexus symptoms: prior neck dissection (p = 0.01), concurrent chemotherapy (p = 0.01), and radiation maximum dose (p < 0.001). Cox regression analysis confirmed that both neck dissection (p < 0.001) and radiation maximum dose (p < 0.001) were independently predictive of symptoms. Conclusion: The incidence of brachial plexus–associated neuropathies after radiation therapy for head-and-neck cancer may be underreported. In view of the dose–response relationship identified, limiting radiation dose to the brachial plexus should be considered when possible.

Over the last 20 years, there has been increasing awareness of a subset of squamous cell carcinomas of the head and neck (HNSCC), i.e. HPV-positive HNSCC. These cancers seem to differ somewhat from HPV-negative HNSCC. Patients with HPV-positive HNSCC tend to be younger and have a lower intake...... of tobacco and alcohol. Distinct molecular profiles separate them from HPV-negative cancers and show similarities with HPV-positive cervical SCC. There is evidence that HPV-positive HNSCC is a sexually transmitted disease. Patients with HPV-positive HNSCC are often diagnosed at a late stage with large cystic......-negative HNSCC, and this seems to be related to the immune system. Whether the new vaccines for HPV will protect not only against cervical cancer but also against HPV-positive HNSCC remains unknown....

Small oropharyngeal carcinomas with advanced neck metastases (stage N2 or greater) are common. Patients with small T with large N oropharyngeal carcinoma have high rates of local control but lower rates of regional control when treated with chemoradiotherapy. Clinical assessment after chemoradiotherapy cannot ensure the absence of neck disease. In the last 5 years, we have treated patients with T1-2 with N2-3 oropharyngeal carcinoma with weekly docetaxel radiotherapy followed by planned neck dissection (PND). Our objectives were to clarify the pathologically complete response (CR) rate of neck metastasis after weekly docetaxel radiotherapy, to identify the clinical predictor of residual neck disease, and to determine the mobidity of planned neck dissection. After chemoradiotherapy, all 12 patients had a complete response at the primary site. We conducted 15 neck dissections. Of these, 6 (40%) had positive nodes. The pathological CR rate of neck metastasis was 58.3%, whereas overall 2-year neck control rate was 91.7%. These findings lend support to the role of PND after chemoradiotherapy in N2-3 neck disease. After chemoradiotherapy, clinical parameters including TN status, feasibility of chemoradiotherapy, largest lymph node size or size reduction in MRI, did not identify patients with residual neck disease. We conducted selective neck dissection (SND) in 80% of patients. SND as PND appears to be appropriate in this group of patients because of the low incidence of complications. A further cohort study including the comparison of PND nonenforcement group is necessary to clarify the validity of the addition of PND in weekly docetaxel radiotherapy. (author)

In general, use of the internet by patients in their healthcare is increasing. However, its use specifically among those with head and neck cancer in the UK has not been reported. The aims of this study were to report access to the internet by survivors of head and neck cancer, to indicate where it fits within their information sources, how they have used it, and how they might use it in future. A question on its use has been included in annual surveys of patients since 2006. Patient-reported access to the internet increased from 32% in 2006 to 54% in 2010. There were considerable differences in access by age; currently (2010) 83% of those under 55 years, and 40% of those aged 65-84 years. Binary logistic regression modelling involving age at survey (peducation (psex (p=0.01), gave all three as independent predictors of access. In the 2010 survey 49% (234/473) never used the internet, 10% (49/473) used it rarely, 15% (70/473) used it occasionally, and 25% (120/473) used it often. The main reasons for its use for head and neck cancer were to find information, learn about treatment, side effects, and medication, and obtain advice from members of multidisciplinary teams. The findings of this study show that the internet has an important role for patients in providing information and support about their cancer, although other sources are still very important. Data from the study will help inform those promoting e-health about the type of resource that is wanted by patients. Copyright © 2011 The British Association of Oral and Maxillofacial Surgeons.

Assess impact of sequential chemoradiation therapy (SCRT) for advanced head and neck cancer (HNCA) on swallowing, nutrition, and quality of life. Prospective cohort study of 59 patients undergoing SCRT for advanced head and neck cancer. Follow-up median was 47.5 months. Regional Cancer Center. Median time to gastrostomy tube removal was 21 weeks. Eighteen of 23 patients who underwent modified barium swallow demonstrated aspiration; none developed pneumonia. Six of 7 with pharyngoesophageal stricture underwent successful dilatation. Functional Assessment of Cancer Therapy-Head and Neck Scale questionnaires at median 6 months after treatment revealed "somewhat" satisfaction with swallowing. At the time of analysis, 97% have the gastronomy tube removed and take soft/regular diet. Early after treatment dysphagia adversely affected weight, modified barium swallow results, and quality of life. Diligent swallow therapy, and dilation as needed, allowed nearly all patients to have their gastronomy tubes removed and return to a soft/regular diet. Dysphagia is significant after SCRT but generally slowly recovers 6 to 12 months after SCRT. C-4.

Full Text Available Purpose: Based on Portuguese experience, current practice does not focus sufficiently on the caregiver needs through caring of the cancer patient. Understanding the impact of different tumor types on caregiver burden, quality of life, and distress may help with organizing resources more efficiently to provide enhanced support for patients and caregivers. Methods: Ninety main caregivers of patients with cervix, rectal and head and neck cancer were interviewed at Instituto Português de Oncologia de Lisboa Francisco Gentil. The Portuguese versions of Zarit Burden Interview, Caregiver Quality of Life Index - Cancer (CQOLC Scale and the distress thermometer were used. Results: The majority of caregivers were female (76.7%, median age was 45.5years (20-79, 40% were spouses and 38.7% sons/daughters. Zarit Burden Interview average score was 25.2 ± 11.6, higher on head and neck cancer group. 59.5% of caregivers had moderate burden and no cases of severe burden. Mean quality of life score was 64.8 ± 15.8 which was lower in the head and neck group. Average distress score across the three groups was seven and rectal group presented a lower score than the other two groups. A subgroup analysis (gender, kinship relation, employment status and cohabitation before starting care of caregivers characteristics showed no statistical differences. Conclusion: There were little differences in the experience of caring within caregivers based on the three different cancer groups, although caregivers of patients with head and neck cancer scored consistently worse in the three scales studied. More efforts should be taken to optimize coping strategies for these caregivers, as well as non-cohabitant and active caregivers, who had a worse caring experience.

Recent evidence has suggested links between obesity and outcomes for various types of cancer. This study investigates the impact that body composition has on survival in patients with head and neck cancer. Data prospectively collected from 578 patients were analyzed using Cox regression models to determine independent associations that pretreatment body mass index (BMI) and 3-month weight change have on observed survival. Higher BMIs were associated with better survival (p < .001). Five-year rates ranged from 33.8% for underweight to 75.3% for overweight/obese patients. Patients with stable weight had the highest 5-year rate (72.6%; p = .019), whereas patients who gained ≥5% had worse survival (45.8%) than those who lost ≥5% (65.8%). BMI independently predicted survival, whereas weight change was not an independent predictor. This demonstrated association between BMI and survival provides useful information when offering prognoses and investigating optimal treatments © 2015 Wiley Periodicals, Inc.

From 1967 through 1985, 86 patients with cancer of the paranasal sinuses and 6 patients with cancer of the nasal cavity (excluding sarcoma) were treated by irradiation at the Department of Radiology, Kumamoto National Hospital. The mean age was 60.7. The rate of men to women was 1.2 : 1. The results were as follows ; 1) Fifty-nine patients (51 cases of maxillary sinus carcinoma, 4 of ethmoid sinus carcinoma, and 4 of cancer of the nasal cavity) were treated with antrostomy followed by radiotherapy and regional arterial infusion of 5-fluorouracil alone or a combination of 5-fluorouracil and bleomycin. In 11 cases of these, salvage with total maxillectomy was performed and 10 % of which were controlled for more than five years. In 9 cases of these, no case was salvaged with radiotherapy. An overall five-year survival rate was 32 %. 2) The survival rate of the postoperative irradiation (11 cases of maxillary sinus carcinoma, 1 of cancer of the nasal cavity) was 42 % at 2 and 4 years after the operations. 3) Twelve patients with cancer of the paranasal sinuses (11 cases of maxillary sinus carcinoma, 1 of ethmoid sinus carcinoma) survived more than five years. All of them were irradiated curatively with doses more than 40 Gy. In our series, there was no difference in long-term survival between 5-fluorouracil alone and a combination of 5-fluorouracil and bleomycin. (author)

Objective: To evaluate the role of PET/CT in the approach to patients with head and neck cancer. Materials and Methods: Retrospective study of medical records and PET/CT images of 63 patients with head and neck cancer. Results: Alterations were observed in 76% of the cases. Out of these cases, 7 (11%) were considered as false-positive, with SUV < 5.0. PET/CT demonstrated negative results in 15 cases (24%). Among the 14 cases where the method was utilized for staging, 3 (22%) had their stages changed. Conclusion: PET/CT has shown to be of potential value in the routine evaluation of patients with head and neck cancer, but further studies of a higher number of cases are required to define a protocol for utilization of the method.

Purpose: To evaluate the effect of continued cigarette smoking among patients undergoing radiation therapy for head-and-neck cancer by comparing the clinical outcomes among active smokers and quitters. Methods and Materials: A review of medical records identified 101 patients with newly diagnosed squamous cell carcinoma of the head and neck who continued to smoke during radiation therapy. Each active smoker was matched to a control patient who had quit smoking before initiation of radiation therapy. Matching was based on tobacco history (pack-years), primary site, age, sex, Karnofsky Performance Status, disease stage, radiation dose, chemotherapy use, year of treatment, and whether surgical resection was performed. Outcomes were compared by use of Kaplan-Meier analysis. Normal tissue effects were graded according to the Radiation Therapy Oncology Group/European Organization for the Treatment of Cancer toxicity criteria. Results: With a median follow-up of 49 months, active smokers had significantly inferior 5-year overall survival (23% vs. 55%), locoregional control (58% vs. 69%), and disease-free survival (42% vs. 65%) compared with the former smokers who had quit before radiation therapy (p < 0.05 for all). These differences remained statistically significant when patients treated by postoperative or definitive radiation therapy were analyzed separately. The incidence of Grade 3 or greater late complications was also significantly increased among active smokers compared with former smokers (49% vs. 31%, p = 0.01). Conclusions: Tobacco smoking during radiation therapy for head-and-neck cancer is associated with unfavorable outcomes. Further studies analyzing the biologic and molecular reasons underlying these differences are planned.

Full Text Available Introduction: Pain in advanced head and neck cancer is intractable and many a times difficult to manage with pharmacological agents. Sphenopalatine ganglion (SPG block provides excellent pain relief in patients who are suffering from various types of orofacial pain. Role of radiofrequency ablation (RFA of SPG is described for orofacial cancer pain. Aim: The aim of the study was to observe efficacy and duration of pain relief by RFA of SPG in advanced head and neck cancer patients. Materials and Methods: Thirty-three patients suffering from advanced head and neck cancer were enrolled in this study between September 2013 and February 2016. All patients underwent RFA of SPG, under fluoroscopy guidance following a successful diagnostic block of SPG with local anesthetic. Pain was assessed before the procedure, immediately after the procedure, and during each follow-up visit. Follow-up visits were weekly for 4 weeks and then monthly till the end of life. Patients were continued on oral morphine, but the dose was reduced to one-third of total dose and was adjusted according to patients' requirement during each follow-up. Duration of analgesia, morphine requirements, and incidence of complications were noted. Results: There were 32 males and one female. Mean age of patients was 43.24 ± 13.52 (mean ± standard deviation [SD], ranging from 19 to 58 years. Three patients did not undergo RFA due to cheek hematoma formation during the procedure. Visual analog score was reduced from 8.43 ± 1.10 (preprocedure to 1.36 ± 1.61 (postprocedure (mean ± SD. Mean duration of analgesia was 17.55 ± 26.12 (mean ± SD weeks. Mean reduction in the dose of morphine was from 124.65 ± 46.78 to 40.00 ± 18.05 mg (mean ± SD immediately after the procedure. One patient was followed up for 30 months. Sixteen patients died within 3 months and had good pain relief. None of the patients had any serious complications. Conclusion: RFA of SPG is a good adjuvant method of pain

The importance of quality-of-life (QoL) research has been recognised over the past two decades in patients with head and neck (H&N) cancer. The aims of this systematic review are to evaluate the QoL status of H&N cancer survivors one year after treatment and to identify the determinants affecting their QoL. Pubmed, Medline, Scopus, Sciencedirect and CINAHL (2000-2011) were searched for relevant studies, and two of the present authors assessed their methodological quality. The characteristics and main findings of the studies were extracted and reported. Thirty-seven studies met the inclusion criteria, and the methodological quality of the majority was moderate to high. While patients of the group in question recover their global QoL by 12 months after treatment, a number of outstanding issues persist - deterioration in physical functioning, fatigue, xerostomia and sticky saliva. Age, cancer site, stage of disease, social support, smoking, feeding tube placement and alcohol consumption are the significant determinants of QoL at 12 months, while gender has little or no influence. Regular assessments should be carried out to monitor physical functioning, degree of fatigue, xerostomia and sticky saliva. Further research is required to develop appropriate and effective interventions to deal with these issues, and thus to promote the patients' QoL. Copyright © 2012 Elsevier Ltd. All rights reserved.

Background: Cancer is a unique disease characterized by abnormal growth of cells which have the ability to invade the adjacent tissues and sometimes even distant organs. The limited and contrasting evidence regarding the association of ABO blood groups with the different types of head and neck cancers in the Indian population warrants the need for the present study. Aim and Objective: To assess the relative risk of various Head & Neck cancers among different blood groups. Materials and Method: Three hundred sixty two diagnosed cases of different type of head and neck cancers and 400 controls were selected from four hospitals of New Delhi, India. The information regarding the type of head and neck cancer was obtained from the case sheets of the patients regarding their socio demographic profile, dietary history using a structured performa. The information regarding type of cancer (cases only), ABO blood group was collected. Statistical Tests: The data was analysed using the SPSS 19 version. Chi square test and odd ratios were calculated. The level of significance was fixed at 5%. Results: The O blood group was found to be most prevalent followed by B, A and AB among the cases as well as the controls. Oral cancer patients showed maximum number in blood group O followed by B, A and AB. Significant pattern of distribution was seen among the patients of esophageal cancer, laryngeal cancer and salivary gland cancer as well (p= 0.003, p=0.000 p=0.112 respectively. Conclusion: The present study reveals that there is an inherited element in the susceptibility or protection against different types of head and neck cancers. Blood group A was found to be a potential risk factor for the development of oral cancers, esophageal cancers and salivary gland cancers while blood group B was found to be a potential risk factor for laryngeal cancers.

To determine the impact of pretreatment psychosocial distress on compliance to radiation therapy (RT) and clinical outcomes for patients with head and neck cancer STUDY DESIGN: Self-reported responses to the mood and anxiety domains of the University of Washington Quality of Life instrument were reviewed among 133 patients with newly diagnosed head and neck cancer prior to initiating RT. Varying definitions were used (total number of unexpectedly missed RT days, >5 days continuous interruption of RT outside of weekends, >10 days continuous interruption of RT, and failure to complete prescribed course of RT) to analyze the effect of psychosocial disruption on compliance. Survival was determined using the Kaplan-Meier method. The prevalence of pretreatment depression and anxiety was 23% and 47%, respectively. Continuous RT breaks >5 days occurred in 46%, 33%, 10%, 9%, and 0% of patients whose mood was rated as "extremely depressed," "somewhat depressed," "neither in a good mood or depressed," "generally good," and "excellent," respectively (P = .0016). The corresponding proportion of patients who did not complete their planned RT was 23%, 11%, 5%, and 3%, and 0%, respectively (P = .043). The 2-year overall survival of patients who were "extremely depressed" or "somewhat depressed" at baseline was 71% versus 86% for all others (P = .026). Depression was independently associated with decreased overall survival on logistical regression analysis. Pretreatment depression predicted for decreased RT compliance and inferior survival for head and neck cancer. Additional research to overcome potential barriers to treatment in this setting may be warranted. 4.

The immediate and permanent frequency of injury to the marginal mandibular branch of the facial nerve (MMN) after neck dissection has only scarcely been addressed in the medical literature. We investigated the risk of injury in 159 consecutive patients after neck dissection for various reasons...... in level I B and level II A, respectively. In 95 patients with oral cancer 13 (14%) of the cases had malfunction of the lower lip domain 2 weeks after neck dissection in level I B indicating paresis to the MMN. Follow-up analyses 1-2 years after the operation showed permanent paralysis in 4 to 7......% of the cases in whom two of them had the nerve sacrificed for oncologic reasons during the operation. In 18 patients with parotic cancer the corresponding permanent frequency of MMN paralysis was 11.1%. In 46 patients with neck dissection in level II A but not in level I B, no paresis of the MMN was registered...

Full Text Available Radiation therapy for head and neck cancer frequently caused severe salivary gland dysfunction. The salivary gland dysfunction possibly decreased the protective function of saliva and caused dental caries. The purpose of this study was to obtain an illustration about DMF-T index in patient undergoing radiation therapy with LINAC X-ray radiation for head and neck cancer at Department of Radiotherapy, Dr. Hasan Sadikin Hospital in January-February 2007. The study was a simple descriptive. The study was conducted on 7 males and 9 females undergoing radiation therapy with LINAC X-ray radiation for head and neck cancer. The ages of patient are between 37 years and 77 years. The severity of caries was measured by DMF-T index. DMF-T index in 16 patient undergoing radiation therapy with LINAC X-ray radiation for head and neck cancer at Dr. Hasan Sadikin Hospital is 10.6 as the result of this study. The conclusion of this study showed that the DMF-T index in 16 patient undergoing radiation therapy with LINAC X-ray radiation for head and neck cancer at Dr. Hasan Sadikin Hospital had very high grade based on WHO classification, which the value was over 6.6.

Chemotherapy and radiotherapy for elderly head and neck cancer patients

Among head and neck cancers, cases affecting elderly people are increasing. Radical treatment is sometimes difficult in advanced cases of elderly patients. With progressive cancer, because radical surgery is often difficult, radiotherapy is chosen and may be used together with chemotherapy when overall status is good. However, according to the meta-analysis of Pignon et al., the chemoradiotherapy for elderly patients 71 years old or older, the hazard ratio becomes approximately 0.95, and there is little chemotherapy combined effect. In terms of 5-year survival rate, chemotherapy combined effect is -0.7%. Chemotherapy effect in elderly patients is not clear in past clinical trials. We examined 50 cases 75 years or older treated mainly by radiotherapy at Tokyo Medical Center between February, 2003 and August, 2011. In all, 21 of the 50 patients died, including four who died due to other cancers, while pneumonia accounted for five other deaths. These results suggested that various complications are often present and multiple primary cancers often occur in elderly people. With chemotherapy for elderly people, the effect of radiotherapy treatment and quality of life of the patients should be considered fully based on characteristics of elderly people, and a treatment plan devised accordingly. It is also necessary to undertake care after treatment. (author)

Reduction of xerostomia in head and neck cancer patients. A critical review of the literature

International Nuclear Information System (INIS)

Hanley, O.; Leech, M.

2016-01-01

Background: Radical radiotherapy given with or without concurrent chemotherapy is the main treatment modality in non-surgical patients for the management of squamous cell carcinoma in the head and neck. Xerostomia, which results from reduced salivary production is a debilitating side-effect of radiation therapy to these patients. Xerostomia may greatly impact on quality of life for head and neck cancer patients for up to 24 months post-radiation therapy. Such effects include difficulties in fundamental daily activities such as speech, mastication and swallowing. It is believed that modulated techniques provide better sparing to surrounding salivary glands. The aim of this critical review of the literature is to investigate what advantage intensity modulated radiotherapy (IMRT) can provide over 3 dimensional conformal radiation therapy (3DCRT) in reducing xerostomia in this subset of patients. Search methodology: An extensive literature search was undertaken to compare the incidence of grade 2 or worse xerostomia in HNSCC patients treated with IMRT or 3DCRT (±chemotherapy). Results: Studies reported a lower incidence of grade 2 or worse xerostomia with IMRT over patients treated with 3DCRT. The highest incidence of xerostomia was reported at 6 months following the completion of radiotherapy treatment. The incidence of xerostomia in patients declined with time, in both patients treated with IMRT and those of the 3DCRT cohort. The incidence of xerostomia was greater in the acute setting than in the late. Conclusion: An IMRT technique can consistently reduce grade 2 or worse xerostomia in head and neck cancer patients over conformal techniques. This will not compromise dose homogeneity or dose coverage. IMRT should remain the standard of care for head and neck patients. - Highlights: • IMRT technique can consistently reduce grade 2 or worse xerostomia in head and neck cancer patients over 3DCRT. • IMRT does not compromise the treatment's dose homogeneity or

Purpose: To determine whether a course of hyperfractionated radiation therapy concomitant with escalated radiosensitizing platinum compounds can be administered with acceptable morbidity and achieve a high rate of loco-regional control for Stage III and IV head and neck cancer and whether the patients can be tumor free at the primary site after initial therapy and cured by the additional chemoradiation without radical resection of the primary tumor. Methods and Materials: Patients with Stage III/IV head and neck cancer were treated in this multicenter Phase II Study with 1.8 Gy fraction radiotherapy for 2 weeks, with escalation to 1.2 Gy b.i.d. hyperfractionation to 46.8 Gy. Concomitant continuous infusion cisplatinum (CDDP) 20 mg per meter square on day 1 to 4 and 22 to 25 was given. Reassessment by biopsy of primary and nodes was done. Patients with a complete response continued with hyperfractionated radiotherapy to 75.6 Gy with simultaneous carboplatinum (Carbo), 25 mg per meter square b.i.d. for 12 consecutive treatment days. Patients with residual disease at 46.8 Gy required curative surgery. Seventy-four patients were treated at the three institutions; 20 were Stage III and 54 were Stage IV. All patients had daily mouth care, nutritional, and psychosocial support. Results: This regime was well tolerated. Eighty-five percent of toxicities were Grade 1 or 2 and there was only one Grade 4 hematologic toxicity. Late toxicities included xerostomia in 25 patients, dysplasia in 18, and mild speech impediment in 11. Biopsies of primary site were done after the first course of treatment in 59 patients. Neck dissections were performed in 35 patients. Forty-four of 59 (75%) primary sites and 16 of 35 (46%) lymph nodes had pathologically complete response (CR). Of the 74 patients, only 12 required surgical resection of the primary site. Thirty-five of the 50 node positive patients had neck dissections, 16 of these were CRs at surgery. At 4 years (median follow-up of 26

Head and neck cancer of unknown primary (HNCUP) is rare and prospective studies are lacking. The impact of different prognostic factors such as age and N stage is not completely known, the optimal treatment is not yet established, and the reported survival rates vary. In the last decade, human papilloma virus (HPV) has been identified as a common cause of and important prognostic factor in oropharyngeal cancer, and there is now growing interest in the importance of HPV for HNCUP. The aim of the present study on curatively treated HNCUP was to investigate the prognostic importance of different factors, including HPV status, treatment, and overall survival. A search for HNCUP was performed in the Swedish Cancer Registry, Western health district, between the years 1992-2009. The medical records were reviewed, and only patients with squamous cell carcinoma or undifferentiated carcinoma treated with curative intent were included. The tumor specimens were retrospectively analyzed for HPV with p16 immunostaining. Sixty-eight patients were included. The mean age was 59 years. The majority were males, and had N2 tumors. Sixty-nine percent of the tumors were HPV positive using p16 staining. Patients who were older than 70 years, patients with N3-stage tumors, and patients with tumors that were p16 negative had a significantly worse prognosis. The overall 5-year survival rate for patients with p16-positive tumors was 88% vs 61% for p16-negative tumors. Treatment with neck dissection and postoperative radiation or (chemo) radiation had 81 and 88% 5-year survival rates, respectively. The overall and disease-free 5-year survival rates for all patients in the study were 82 and 74%. Curatively treated HNCUP had good survival. HPV infection was common. Independent prognostic factors for survival were age over 70 years, HPV status and N3 stage. We recommend that HPV analysis should be performed routinely for HNCUP. Treatment with neck dissection and postoperative radiation or

Previous studies have established that a subset of head and neck tumors contains human papillomavirus (HPV) sequences and that HPV-driven head and neck cancers display distinct biological and clinical features. HPV is known to drive cancer by the actions of the E6 and E7 oncoproteins, but the molecular architecture of HPV infection and its interaction with the host genome in head and neck cancers have not been comprehensively described. We profiled a cohort of 279 head and neck cancers with next generation RNA and DNA sequencing and show that 35 (12.5%) tumors displayed evidence of high-risk HPV types 16, 33, or 35. Twenty-five cases had integration of the viral genome into one or more locations in the human genome with statistical enrichment for genic regions. Integrations had a marked impact on the human genome and were associated with alterations in DNA copy number, mRNA transcript abundance and splicing, and both inter- and intrachromosomal rearrangements. Many of these events involved genes with documented roles in cancer. Cancers with integrated vs. nonintegrated HPV displayed different patterns of DNA methylation and both human and viral gene expressions. Together, these data provide insight into the mechanisms by which HPV interacts with the human genome beyond expression of viral oncoproteins and suggest that specific integration events are an integral component of viral oncogenesis.

Computed tomography (CT), combined positron emitted tomography and CT (PET/CT), and magnetic resonance imaging (MRI) are commonly used in head and neck radiation planning. Hybrid PET/MRI has garnered attention for potential added value in cancer staging and treatment planning. Herein, we compare PET/MRI vs. planning CT for head and neck cancer gross tumor volume (GTV) delineation. We prospectively enrolled patients with head and neck cancer treated with definitive chemoradiation to 60-70 Gy using IMRT. We performed pretreatment contrast-enhanced planning CT and gadolinium-enhanced PET/MRI. Primary and nodal volumes were delineated on planning CT (GTV-CT) prospectively before treatment and PET/MRI (GTV-PET/MRI) retrospectively after treatment. GTV-PET/MRI was compared to GTV-CT using separate rigid registrations for each tumor volume. The Dice similarity coefficient (DSC) metric evaluating spatial overlap and modified Hausdorff distance (mHD) evaluating mean orthogonal distance difference were calculated. Minimum dose to 95% of GTVs (D95) was compared. Eleven patients were evaluable (10 oropharynx, 1 larynx). Nine patients had evaluable primary tumor GTVs and seven patients had evaluable nodal GTVs. Mean primary GTV-CT and GTV-PET/MRI size were 13.2 and 14.3 cc, with mean intersection 8.7 cc, DSC 0.63, and mHD 1.6 mm. D95 was 65.3 Gy for primary GTV-CT vs. 65.2 Gy for primary GTV-PET/MRI. Mean nodal GTV-CT and GTV-PET/MRI size were 19.0 and 23.0 cc, with mean intersection 14.4 cc, DSC 0.69, and mHD 2.3 mm. D95 was 62.3 Gy for both nodal GTV-CT and GTV-PET/MRI. In this series of patients with head and neck (primarily oropharynx) cancer, PET/MRI and CT-GTVs had similar volumes (though there were individual cases with larger differences) with overall small discrepancies in spatial overlap, small mean orthogonal distance differences, and similar radiation doses.

Oral mucositis in head and neck cancer: risk, biology, and management.

Sonis, Stephen T

Of the toxicities associated with conventional forms of treatment for head and neck cancers, probably none has such a consistent legacy as oral mucositis.1 Despite the fact that mucosal injury was noted as far back as Marie Curie's first forays into therapeutic radiation, an effective intervention has yet to be developed. In addition to its historic link to radiation, new therapeutic strategies including induction chemotherapy often produce mucositis, and targeted therapies appear to alter mucositis risk and its severity and course.2 The symptomatic effect of oral mucositis is profound. Disabling oral and oropharyngeal pain prevents patients from eating normally, requires opiate analgesics, and in some cases results in alteration or discontinuation of anticancer therapy.3 Furthermore, the health and economic consequences of oral mucositis are far from trivial. The incremental cost of oral mucositis in patients with head and neck cancer exceeds $17,000 (USD).4.

The purpose of this study is to systematically explore the motives for patients with head and neck cancer to contact a specialist nurse during two years postdiagnosis. Research focusing on the role of specialist nurses in cancer care almost exclusively concern cancers other than head and neck cancer. Qualitative, descriptive study based on the contacts between patients with head and neck cancer and a specialist nurse. Patients were invited to contact a specialist nurse by telephone. The specialist nurse took systematic field notes, that is, she registered who contacted her, the nature of the call and the outcome. Sixty patients were included. In descending order, the motives for contact were questions about practical and uncomplicated matters, consultations about medical troubles/worries, presenting a report of the patient's situation, requests for additional information about the treatment plan and requests for medical information. The pattern of the patients' motivations for calling was not related to medical or social factors, suggesting that the initiative to make contact is very much a question of the complexity of individual life circumstances. Very few referrals were sent from the specialist nurse to other professionals. The specialist nurse turned out to be more than just a coordinator of health-care resources. The findings bring up questions about the potential of the nurse's function as a coordinator, but also as a potential attachment figure, and questions about the nurse's relationships to other professionals. When implementing a specialist nurse function, it is important to decide whether the function should be inspired by a broader relational perspective. In addition to the indispensible competence and experience in the clinical field of head and neck cancer, training in counselling and acquaintance with object-relational psychology will then be desirable. © 2016 John Wiley & Sons Ltd.

Purpose: To review our 15-year institutional experience using intensity modulated radiation therapy (IMRT) to reirradiate patients with head and neck squamous cell carcinomas (HNSCC) and identify predictors of outcomes and toxicity. Methods and Materials: We retrospectively reviewed the records of 227 patients who received head and neck reirradiation using IMRT from 1999 to 2014. Patients treated with noncurative intent were excluded. Radiation-related acute and late toxicities were recorded. Prognostic variables included performance status, disease site, disease-free interval, chemotherapy, and RT dose and volume. Correlative analyses were performed separately for surgery and nonsurgery patients. Results: Two hundred six patients (91%) were retreated with curative intent, and 173 had HNSCC histology; 104 (50%) underwent salvage resection, and 135 (66%) received chemotherapy. Median follow-up after reirradiation was 24.7 months. Clinical outcomes were worse for HNSCC patients, with 5-year locoregional control, progression-free survival, and overall survival rates of 53%, 22%, and 32%, respectively, compared with 74%, 59%, and 79%, respectively, for non-HNSCC patients. On multivariate analysis, concurrent chemotherapy and retreatment site were associated with tumor control, whereas performance status was associated with survival. Favorable prognostic factors specific to surgery patients were neck retreatment and lack of extracapsular extension, whereas for nonsurgery patients, these were a nasopharynx subsite and complete response to induction chemotherapy. Actuarial rates of grade ≥3 toxicity were 32% at 2 years and 48% at 5 years, with dysphagia or odynophagia being most common. Increased grade ≥3 toxicity was associated with retreatment volume >50 cm{sup 3} and concurrent chemotherapy. Conclusions: Reirradiation with IMRT either definitively or after salvage surgery can produce promising local control and survival in selected patients with head and neck

To evaluate the radial displacement of clinical target volume in the patients with node negative head and neck (H and N) cancer and to quantify the relative positional changes compared to that of normal healthy volunteers. Three node-negative H and N cancer patients and fi ve healthy volunteers were enrolled in this study. For setup accuracy, neck thermoplastic masks and laser alignment were used in each of the acquired computed tomography (CT) images. Both groups had total three sequential CT images in every two weeks. The lymph node (LN) level of the neck was delineated based on the Radiation Therapy Oncology Group (RTOG) consensus guideline by one physician. We use the second cervical vertebra body as a reference point to match each CT image set. Each of the sequential CT images and delineated neck LN levels were fused with the primary image, then maximal radial displacement was measured at 1.5 cm intervals from skull base (SB) to caudal margin of LN level V, and the volume differences at each node level were quantified. The mean radial displacements were 2.26 (±1.03) mm in the control group and 3.05 (±1.97) in the H and N cancer patients. There was a statistically significant difference between the groups in terms of the mean radial displacement (p = 0.03). In addition, the mean radial displacement increased with the distance from SB. As for the mean volume differences, there was no statistical significance between the two groups. This study suggests that a more generous radial margin should be applied to the lower part of the neck LN for better clinical target coverage and dose delivery.

The present study aimed to establish exercise preferences, barriers, and perceived benefits among head and neck cancer survivors, as well as their level of interest in participating in an exercise program. Patients treated for primary squamous cell carcinoma of the head and neck between 2010 and 2014 were identified from the hospital database and sent a postal questionnaire pack to establish exercise preferences, barriers, perceived benefits, current physical activity levels, and quality of life. A postal reminder was sent to non-responders 4 weeks later. The survey comprised 1021 eligible patients of which 437 (43%) responded [74% male, median (interquartile range) age, 66 (60-73) years]. Of the respondents, 30% said 'Yes' they would be interested in participating in an exercise program and 34% said 'Maybe'. The most common exercise preferences were a frequency of three times per week, moderate-intensity, and 15-29 min per bout. The most popular exercise types were walking (68%), flexibility exercises (35%), water activites/swimming (33%), cycling (31%), and weight machines (19%). Home (55%), outdoors (46%) and health club/gym (33%) were the most common preferred choices for where to regularly exercise. Percieved exercise benefits relating to improved physical attributes were commonly cited, whereas potential social and work-related benefits were less well-acknowledged. The most commonly cited exercise barriers were dry mouth or throat (40%), fatigue (37%), shortness of breath (30%), muscle weakness (28%) difficulty swallowing (25%), and shoulder weakness and pain (24%). The present findings inform the design of exercise programs for head and neck cancer survivors.

Encouraging data for targeted therapy in head-and-neck squamous cell carcinoma are opening new options for treatment. Phase III trials of cetuximab, an antibody directed against the epidermal growth factor receptor (egfr) have demonstrated benefit in the locally advanced and metastatic settings. Recognizing the importance of emerging therapies, Cancer Care Ontario published guideline recommendations for egfr-targeted therapy in stage iii and iv head-and-neck cancer. The present paper takes a further look at the population for whom an offer of cetuximab therapy may be appropriate. PMID:20697514

Life-threatening diseases, such as head and neck cancer (HNCa), can stimulate the emergence of a new disease-specific self-concept. We hypothesized that (i) negative cancer-stereotypes invoke distancing, which inhibits the adoption of a disease-specific self-concept and (ii) patient characteristics, disease and treatment factors, and cancer-related stressors moderate the phenomenon. Head and neck cancer outpatients (N = 522) completed a semantic-differential measure of disease-specific self-concept (perceived similarity to the 'cancer patient') and other self-report measures in structured interviews. Negative cancer-stereotypes were represented by the number of semantic-differential dimensions (0-3) along which respondents evaluated the stereotypic 'cancer patient' negatively (i.e., negative valence). We tested the two-way interactions between negative valence and hypothesized moderator variables. We observed significant negative valence × moderator interactions for the following: (i) patient characteristics (education, employment, social networks); (ii) disease and treatment factors (cancer-symptom burden); and (iii) cancer-related stressors (uncertainty, lack of information, and existential threats). Negative cancer stereotypes were consistently associated with distancing of self from the stereotypic 'cancer patient,' but the effect varied across moderator variables. All significant moderators (except employment and social networks) were associated with increasing perceived similarity to the 'cancer patient' when respondents maintained negative stereotypes; perceived similarity decreased when people were employed or had extensive social networks. Moderator effects were less pronounced when respondents did not endorse negative cancer stereotypes. When they hold negative stereotypes, people with HNCa distance themselves from a 'cancer patient' identity to preserve self-esteem or social status, but exposure to cancer-related stressors and adaptive demands may

Concurrent chemoradiotherapy (CCRT) is one of the recent emerging modalities for advanced squamous cell carcinoma of the head and neck (HNSCC). However some of the patients treated by CCRT have residual or recurrent cervical lymph nodes. In these cases, neck dissection is considered to be useful in the point of locolegional control and disease free survival. This study aims to analyze neck control rate by CCRT and usefulness of the neck dissection after CCRT for HNSCC. The medical records of 69 consecutive patients (stage III: 4%, stage IV: 96%) treated with CCRT for SCCHN (hypopharynx: 40, oropharynx: 25, larynx: 4) from 2003 through 2007 were reviewed. Clinical complete response (CR) rates of N1, N2a, N2b, N2c and N3 were 75%, 100%, 71%, 74% and 43% respectively. Among the patients with complete neck response, only 2 patients (5%) had an isolated neck recurrence. Eleven patients underwent surgical neck procedures including 7 planned neck dissections and 4 salvage neck dissections. All the 11 patients with neck dissections had good regional control except 1 case. There were a few minor complications such as wound infection and laryngeal edema. Patients who have a complete clinical regional response to CCRT have a low probability of an isolated recurrence in the neck. Planned and salvage neck dissections can be safely performed and considered to be useful in the point of regional control after intensive CCRT. (author)

Purpose: To determine the optimal clinical target volume margins around the gross nodal tumor volume in head-and-neck cancer by assessing microscopic tumor extension beyond cervical lymph node capsules. Methods and Materials: Histologic sections of 96 dissected cervical lymph nodes with extracapsular extension (ECE) from 48 patients with head-and-neck squamous cell carcinoma were examined. The maximum linear distance from the external capsule border to the farthest extent of the tumor or tumoral reaction was measured. The trends of ECE as a function of the distance from the capsule and lymph node size were analyzed. Results: The median diameter of all lymph nodes was 11.0 mm (range: 3.0-30.0 mm). The mean and median ECE extent was 2.2 mm and 1.6 mm, respectively (range: 0.4-9.0 mm). The ECE was <5 mm from the capsule in 96% of the nodes. As the distance from the capsule increased, the probability of tumor extension declined. No significant difference between the extent of ECE and lymph node size was observed. Conclusion: For N1 nodes that are at high risk for ECE but not grossly infiltrating musculature, 1 cm clinical target volume margins around the nodal gross tumor volume are recommended to cover microscopic nodal extension in head-and-neck cancer

To describe long-term changes in time of quality of life (QOL) and the relation with parotid salivary output in patients with head-and-neck cancer treated with radiotherapy. Forty-four patients completed the EORTC-QLQ-C30(+3) and the EORTC-QLQ-H&N35 questionnaires before treatment, 6 weeks, 6 months, 12 months, and at least 3.5 years after treatment. At the same time points, stimulated bilateral parotid flow rates were measured. There was a deterioration of most QOL items after radiotherapy compared with baseline, with gradual improvement during 5 years follow-up. The specific xerostomia-related items showed improvement in time, but did not return to baseline. Global QOL did not alter significantly in time, although 41% of patients complained of moderate or severe xerostomia at 5 years follow-up. Five years after radiotherapy the mean cumulated parotid flow ratio returned to baseline but 20% of patients had a flow ratio <25%. The change in time of xerostomia was significantly related with the change in flow ratio (p = 0.01). Most of the xerostomia-related QOL scores improved in time after radiotherapy without altering the global QOL, which remained high. The recovery of the dry mouth feeling was significantly correlated with the recovery in parotid flow ratio

The effects of radiotherapy on the oral hard and soft tissues may range from a mild mucositis to severe caries and osteoradionecrosis. It is the responsibility of the dentist to treat and prevent the severe sequelae which may arise. This paper outlines the effects of radiotherapy on the oral structures and discusses the dental treatment of the patient during radiotherapy. Emphasis is placed on the prevention of complications. The head and neck cancer patient must be thoroughly examined by the dentist and treatment planning may then be divided into pre-irradiaton treatment, treatment during irradiation and post-irradiation treatment.

Purpose: Interindividual variability in normal tissue toxicity during radiation therapy is a limiting factor for successful treatment. Predicting the risk of developing acute reactions before initiation of radiation therapy may have the benefit of opting for altered radiation therapy regimens to achieve minimal adverse effects with improved tumor cure. Methods and Materials: DNA double-strand break (DSB) induction and its repair kinetics in lymphocytes of head-and-neck cancer patients undergoing chemoradiation therapy was analyzed by counting {gamma}-H2AX foci, neutral comet assay, and a modified version of neutral filter elution assay. Acute normal tissue reactions were assessed by Radiation Therapy Oncology Group criteria. Results: The correlation between residual DSBs and the severity of acute reactions demonstrated that residual {gamma}-H2AX foci in head-and-neck cancer patients increased with the severity of oral mucositis and skin reaction. Conclusions: Our results suggest that {gamma}-H2AX analysis may have predictive implications for identifying the overreactors to mucositis and skin reactions among head-and-neck cancer patients prior to initiation of radiation therapy.

Single-modality radiotherapy is considered a standard-of-care option for certain stage III, T1-2N1 head and neck squamous cell carcinomas (HNSCCs). The role of concomitant chemoradiation is not well established because there have been no studies comparing chemoradiation with radiation alone in this population. This study analyzed patients in the National Cancer Data Base with cT1-2N1M0 invasive squamous cell carcinomas of the oropharynx, larynx, and hypopharynx who were diagnosed between 2004 and 2012 and were undergoing definitive radiation. Patients who were undergoing surgery before radiation with unknown follow-up or for whom either the receipt or timing of chemotherapy was unknown were excluded. In all, 5030 patients with T1-2N1 oropharyngeal, laryngeal, or hypopharyngeal cancer were included. The median follow-up was 56.8 months (95% confidence interval [CI], 55.7-58.6 months). Overall, 68% of the patients received concomitant chemoradiation (CCRT). The use of CCRT significantly increased during the time period of this study from 53% in 2004 to 78% in 2012 (P cancer (HR, 0.74; 95% CI, 0.65-0.85; P Cancer 2017;123:1555-1565. © 2017 American Cancer Society. © 2016 American Cancer Society.

Moving Toward Bioadjuvant Approaches to Head and Neck Cancer Prevention

Saba, Nabil F.; Hammond, Anthea; Shin, Dong M.; Khuri, Fadlo R.

2007-01-01

Head and neck squamous cell carcinoma affects >45,000 Americans annually. Patients who are successfully treated for their primary tumor are at high risk of developing a second primary tumor, making effective preventive strategies highly desirable for this disease. Although a landmark study in 1990 suggested some benefit of high-dose retinoids in head and neck cancer prevention, subsequent trials using more tolerable doses have shown limited clinical success. Newer preventive strategies have included bioadjuvant therapy combining retinoids with interferon and α-tocopherol, combinations of molecularly targeted agents, and oncolytic viruses. Furthermore, considerable evidence has supported a cancer protective role for several nutrients, including green tea and curcumin analogs. Natural compounds such as these with favorable long-term safety profiles might be particularly suited to the cancer prevention setting, in which patients will usually tolerate only moderate risk and toxicity

Palliative radiotherapy in head and neck cancers: Evidence based review

Full Text Available Squamous cell carcinoma of head and neck (SCCHN is one of the commonest cancers seen in India, constituting up to 25% of their overall cancer burden. Advanced SCCHN is a bad disease with a poor prognosis and patients usually die of uncontrolled loco-regional disease. Curative intent management of loco-regionally advanced SCCHN has become more evidence-based with active clinical research in the form of large prospective randomized controlled trials and meta-analyses. However, little has been written about palliative radiotherapy (PRT in head and neck cancers. It is widely recognized that PRT provides effective palliation and improved quality-of-life in advanced incurable malignancies. It is in this context that this study proposes to review the existing literature on palliative radiotherapy in advanced incurable SCCHN to help formulate consensus guidelines and recommendations.

Comparison between Japanese and French interstitial brachytherapy for head and neck cancer

Interstitial brachytherapy is the optimal radiotherapy modality for head and neck cancer because the highest dose conformity can be achieved, and implanted tubes can move synchronously with the tumor movement. Compared with radical surgery, interstitial brachytherapy can achieve equivalent local control with less morbidity and less functional deficit. In Japan, because of technical limitations, interstitial brachytherapy has been confined to treatment of small tongue cancers. To improve our head and neck cancer treatment, technical limitations should be eliminated and a wider indication for interstitial brachytherapy should be achieved. In France, interstitial brachytherapy has been technically more developed and widely indicated than in Japan. We analyzed the differences between Japanese (Osaka) and French (Lyon and Nancy) techniques, to improve our interstitial brachytherapy. Implant devices and techniques: French applicators (Longcip 1) are more flexible and more suitable for loop techniques of the soft palate, the base of the tongue, and the vallecula, than applicators available in Japan. Various implant techniques are established especially for the oropharynx in France. Mandibular protection: Lead blocks used in France can more effectively shield the mandible than our silicone spacers. We showed the dosimetric results in an experimental treatment setting. Dose specification: The five-mm dose specification method used in Japan can work only for easy cases, such as small oral tongue cancers and mouth floor cancers. For complicated implants, such as for the oropharynx, the CTV-based dose specification method used in France is essential for sufficient irradiation. Indications: The indication for head and neck interstitial brachytherapy in Japan is limited mostly to small oral tongue cancers. The indication in France is wider, including the oral cavity, the oropharynx, and postoperative cases. We can refine our head and neck cancer treatment if we combine French

The treatment of head and neck cancer is associated with significant dysphagia and morbidity. Prescribing a safe oral diet in this population is challenging. Data from 116 consecutive patients having 189 fiber-optic endoscopic evaluation of swallowing (FEES) examinations over a 3-year period were analyzed. All patients had been treated for head and neck cancer and subsequently were assessed by FEES. The primary outcome was the incidence of swallowing-related adverse events resulting from the FEES-based dietary recommendations. There were 10 episodes of aspiration pneumonia, 4 episodes of airway obstruction, 3 unanticipated insertions of gastrostomy tubes, and 2 unexplained deaths within the study period. The overall rate of adverse events was 10.1%. The only statistically significant predictor of adverse events was the Rosenbek score (p = .03). Our experience is that FEES guides appropriate and safe diet recommendations in this population. Copyright © 2012 Wiley Periodicals, Inc.

Delayed damage after radiation therapy for head and neck cancer

I investigated radiation damage, including osteoradionecrosis, arising from tooth extraction in fields that had received radiation therapy for head and neck cancer, and evaluated the effectiveness of pilocarpine for xerostomia. Between January 1990 and April 1996, I examined 30 patients for bone changes after tooth extraction in fields irradiated at the Department of Oral Radiology, Osaka Dental University Hospital. Nineteen of the patients had been treated for nasopharyngeal cancer and 11 for oropharyngeal cancer. Between January and April 1996, 4 additional patients were given pilocarpine hydrochloride (3-mg, 6-mg and 9-mg of KSS-694 orally three times a day) for 12 weeks and evaluated every 4 weeks as a base line. One had been treated for nasopharyngeal carcinoma, two for cancer of the cheek and one for an unknown carcinoma. Eighteen of the patients (11 with nasopharyngeal carcinoma and 7 with oropharyngeal carcinoma) had extractions. Use of preoperative and postoperative radiographs indicated that damage to the bone following tooth extraction after radiation exposure was related to whether antibiotics were administered the day before the extraction, whether forceps or elevators were used, and whether the tooth was in the field of radiation. Xerostomia improved in all 4 of the patients who received 6-mg or 9-mg of pilocarpine. It improved saliva production and relieved the symptoms of xerostomia after radiation therapy for head and neck cancer, although there were minor side effects such as fever. This information can be used to improve the oral environment of patients who have received radiation therapy for head and neck cancer, and to better understand their oral environment. (author)

Purpose: Elevated expression of eukaryotic protein synthesis initiation factor 4E (eIF4E) in histologically cancer-free margins of resected head and neck squamous cell carcinomas (HNSCCs) is mediated by mammalian target of rapamycin complex 1 (mTORC1) and has been associated with increased risk of disease recurrence. Preclinically, inhibition of mTORC1 with everolimus sensitizes cancer cells to cisplatin and radiation. Methods and Materials: This was single-institution phase 1 study to establish the maximum tolerated dose of daily everolimus given with fixed dose cisplatin (30 mg/m{sup 2} weekly × 6) and concurrent intensity modulated radiation therapy for patients with locally and/or regionally advanced head-and-neck cancer. The study had a standard 3 + 3 dose-escalation design. Results: Tumor primary sites were oral cavity (4), salivary gland (4), oropharynx (2), nasopharynx (1), scalp (1), and neck node with occult primary (1). In 4 of 4 cases in which resected HNSCC surgical pathology specimens were available for immunohistochemistry, elevated expression of eIF4E was observed in the cancer-free margins. The most common grade ≥3 treatment-related adverse event was lymphopenia (92%), and dose-limiting toxicities (DLTs) were mucositis (n=2) and failure to thrive (n=1). With a median follow up of 19.4 months, 2 patients have experienced recurrent disease. The maximum tolerated dose was everolimus 5 mg/day. Conclusions: Head-and-neck cancer patients tolerated everolimus at therapeutic doses (5 mg/day) given with weekly cisplatin and intensity modulated radiation therapy. The regimen merits further evaluation, especially among patients who are status post resection of HNSCCs that harbor mTORC1-mediated activation of eIF4E in histologically negative surgical margins.

The aim of this study was to assess the value of nutritional risk screening-2002 (NRS-2002) as a nutritional risk screening and status assessment method and to compare it with nutritional status assessed by subjective and objective methods in the screening of head and neck cancer patients. Sixty-five consecutive patients (50 male), with a median age of 61 years (range, 33-77), with head and neck squamous cell carcinoma (HNSCC) were enrolled prior to cancer therapy. Nutritional status was assessed by NRS-2002, patient-generated subjective global assessment (PG-SGA), handgrip strength (HGS) and mid-arm muscle area (MAMA). Twenty-eight percent of patients were at nutritional risk based on NRS-2002, and 34 % were malnourished according to PG-SGA, while 43 % had low HGS. NRS-2002 cut-off score of ≥3 compared with the nutritional status according to PG-SGA showed 77 % specificity and 98 % sensitivity (K = 0.78). NRS-2002 was able to predict malnutrition (PG-SGA BC) both in men (p nutrition screening in head and neck cancer patients prior to oncological treatment.

Dynamic intensity-modulated non-coplanar arc radiotherapy (INCA) for head and neck cancer

International Nuclear Information System (INIS)

Krayenbuehl, Jerome; Davis, J. Bernard; Ciernik, I. Frank

2006-01-01

Background and purpose: To define the potential advantages of intensity-modulated radiotherapy (IMRT) applied using a non-coplanar dynamic arc technique for the treatment of head and neck cancer. Materials and methods: External beam radiotherapy (EBRT) was planned in ten patients with head and neck cancer using coplanar IMRT and non-coplanar arc techniques, termed intensity modulated non-coplanar arc EBRT (INCA). Planning target volumes (PTV1) of first order covered the gross tumor volume and surrounding clinical target volume treated with 68-70 Gy, whereas PTV2 covered the elective lymph nodes with 54-55 Gy using a simultaneous internal boost. Treatment plan comparison between IMRT and INCA was carried out using dose-volume histogram and 'equivalent uniform dose' (EUD). Results: INCA resulted in better dose coverage and homogeneity of the PTV1, PTV2, and reduced dose delivered to most of the organs at risk (OAR). For the parotid glands, a reduction of the mean dose of 2.9 (±2.0) Gy was observed (p 0.002), the mean dose to the larynx was reduced by 6.9 (±2.9) Gy (p 0.003), the oral mucosa by 2.4 (±1.1) Gy (p < 0.001), and the maximal dose to the spinal cord by 3.2 (±1.7) Gy (p = 0.004). The mean dose to the brain was increased by 3.0 (±1.4) Gy (p = 0.002) and the mean lung dose increased by 0.2 (±0.4) Gy (p = 0.87). The EUD suggested better avoidance of the OAR, except for the lung, and better coverage and dose uniformity were achieved with INCA compared to IMRT. Conclusion: Dose delivery accuracy with IMRT using a non-coplanar dynamic arc beam geometry potentially improves treatment of head and neck cancer

Acetylsalicylic acid (aspirin) and non-steroidal anti-inflammatory drugs (NSAIDs) have been associated with reduced risks for certain human cancers. However, the effects of aspirin and NSAIDs on head and neck squamous cell carcinoma (HNSCC) remain controversial, and the prognostic effects of these drugs in patients with HNSCC are largely unknown. This study examined the clinical impact of aspirin and NSAIDs on disease recurrence and survival in patients with HNSCC. This study analysed a cohort of 1392 consecutive patients who received definitive treatment for previously untreated HNSCC at our tertiary referral center. Aspirin or NSAID use was considered positive if the patients were receiving aspirin or NSAID medication from HNSCC diagnosis to at least 1 year after treatment initiation. Cox proportional hazard models were utilised to determine the association of aspirin and/or NSAID use with recurrence, survival, and second primary cancer occurrence. Of 1392 patients, 81 (5.8%) and 89 (6.4%) received post-diagnosis treatment with aspirin and NSAIDs, respectively. After controlling for clinical factors, aspirin and NSAIDs were not significantly associated with recurrence, survival, or second cancer occurrence (P > 0.05). The cumulative dose of aspirin or NSAIDs did not alter survival outcomes (P > 0.05). Our data illustrated that the use of aspirin or NSAIDs has no effect on survival or recurrence in patients with HNSCC.

Head and neck cancer due to heavy metal exposure via tobacco smoking and professional exposure: A review

Khlifi, Rim; Hamza-Chaffai, Amel

2010-01-01

Chronic exposures to heavy metals via tobacco smoking and professional exposure may increase the risk of head and neck cancer, although the epidemiologic evidence is limited by problems of low study power and inadequate adjustment for tobacco and professional exposure use. Numerous scientific reviews have examined the association of various heavy metals exposure with respiratory cancer as well as other cancer types, but few have been published on head and neck cancer. The purpose of this paper, therefore, is to review the head and neck tract cancer-related data on exposure to heavy metals via smoking and working exposure and to study the major mechanisms underlying some toxic metals carcinogenesis.

Singham, S.; Iyer, G.; Clark, J.

2009-01-01

Full text:Introduction: Pre-treatment evaluation of the presence of cervical nodal metastases is important in head and neck cancers and has major prognostic implications. In this study, we aim to determine the accuracy of CT/PET as a tool for identifying such metastases. Methods: All patients from Royal Prince Alfred and Liverpool Hospitals, who underwent CT/PET for any cancer arising from the head and neck, and who underwent subsequent surgery (which included a neck dissection) within 8 weeks of the CT/PET were included. Nodal staging was undertaken by utilising imaging-based nodal classification, and comparison with pathologic data from the surgical specimen was made. PET was considered positive if the SUV was greater than 2. Results: We identified 111 patients from the above criteria. 80 of such patients were treated for squamous cell carcinoma (SCC). CT/PET identified unsuspected metastatic disease in 6 patients. Correlation of CT/PET findings and the presence of disease at the primary site: sensitivity: 98%, specificity: 93%, positive predictive value (PPV): 98% and negative predictive value (NPV): 93%. Correlating CT/PET findings with the presence of nodal disease at any level: sensitivity: 95%, specificity: 88%, PPV: 95% and NPV: 88%. CT/PET was anatomically accurate in predicting the site of metastases in 62/74 (84%). Conclusion: PET is accurate in predicting both presence of nodal metastases and the level of involvement. CT/PET should be undertaken as a pre-operative tool to assist in planning the extent of surgery required in head and neck cancers.

Improving Therapeutic Ratio in Head and Neck Cancer with Adjuvant and Cisplatin-Based Treatments

Directory of Open Access Journals (Sweden)

Loredana G. Marcu

2013-01-01

Full Text Available Advanced head and neck cancers are difficult to manage despite the large treatment arsenal currently available. The multidisciplinary effort to increase disease-free survival and diminish normal tissue toxicity was rewarded with better locoregional control and sometimes fewer side effects. Nevertheless, locoregional recurrence is still one of the main reasons for treatment failure. Today, the standard of care in head and neck cancer management is represented by altered fractionation radiotherapy combined with platinum-based chemotherapy. Targeted therapies as well as chronotherapy were trialled with more or less success. The aim of the current work is to review the available techniques, which could contribute towards a higher therapeutic ratio in the treatment of advanced head and neck cancer patients.

End-stage head and neck cancer coping mechanisms

Directory of Open Access Journals (Sweden)

Bogdan Popescu

2017-10-01

Full Text Available Coping mechanisms are patients’ means of adapting to stressful situations and involve psychological and physical changes in behavior. Patients adapt to head and neck cancer in a variety of ways. Head and neck cancers are extremely debilitating, especially in advanced stages of the disease or in end-of-life situations. While an oncology team needs to address the needs of all oncology patients, the advanced terminal patients require special attention. Most of these patients do not cope well with their situation and have a tendency to cease social interactions. Pain is the most frequentlyexperienced medical disability in patients having an end-stage illness experience, and thus an important medical endeavor is to afford dignity to the dying patient facingan incurable disease. In such cases, the medical community should never refuse therapy or to assist a dying patient.In some instances, the patient and family may derive benefit from their religious beliefs.

2011-01-01

To study the long-term survival of dental implants placed in native or grafted bone in irradiated bone in subjects who had received radiation for head and neck cancer. A retrospective chart review was conducted for all patients who received dental implants following radiation treatment for head and neck cancer between May 1, 1987 and July 1, 2008. Only patients irradiated with a radiation dose of 50 Gy or greater and those who received dental implants in the irradiated field after head and neck radiation were included in the study. The associations between implant survival and patient/implant characteristics were estimated by fitting univariate marginal Cox proportional hazards models. A total of 48 patients who had prior head and neck radiation had 271 dental implants placed during May 1987-July 2008. There was no statistically significant difference between implant failure in native and grafted bone (P=0.76). Survival of implants in grafted bone was 82.3% and 98.1% in maxilla and mandible, respectively, after 3 years. Survival of implants in native bone in maxilla and mandible was 79.8% and 100%, respectively, after 3 years. For implants placed in the native bone, there was a higher likelihood of failure in the maxilla compared to the mandible and there was also a tendency for implants placed in the posterior region to fail compared to those placed in the anterior region. There was no significant difference in survival when implants were placed in native or grafted bone in irradiated head and neck cancer patients. For implants placed in native bone, survival was significantly influenced by the location of the implant (maxilla or mandible, anterior or posterior).

One hundred and nine patients with advanced head and neck cancers (oral cavity: 50, oropharynx: 11, hypopharynx: 18, larynx: 30) received preoperative radiotherapy from 1987 through 1997 in our institute. The median age was 66 years (20-83). Almost all patients had advanced disease (stage II: 17, III: 34, IV: 58). The median dose of preoperative radiotherapy was 40 Gy (20-50). Seventy patients received chemotherapy. The median follow-up time was 30 months. The 5-year overall and disease-free survival rates of all patients were 66% and 56%, respectively. The 5-year locoregional and distant failure rates were 36% and 10%, respectively. The locoregional failure rate of oral cavity cancer (54%) was worse than those of other sites (13-28%) (p=0.0015). The locoregional failure rates of oral cavity cancers according to clinical stage were 59% (II), 57% (III) and 48% (IV), respectively. Incidentally those of other sites were 0% (II), 16% (III) and 30% (IV), respectively. Thirty-eight patients had major complication after surgery. The locoregional failure rates of preoperative radiotherapy following surgery for oral cavity cancers of all stages and other sites of stage IV were high. Preoperative radiotherapy should be stopped and postoperative radiotherapy for these patients should be considered. (author)

We retrospectively review outcomes of applying boron neutron capture therapy (BNCT) to unresectable advanced or recurrent head and neck cancers. Patients who were treated with BNCT for either local recurrent or newly diagnosed unresectable head or neck cancers between December 2001 and September 2007 were included. Clinicopathological characteristics and clinical outcomes were retrieved from hospital records. Either a combination of borocaptate sodium and boronophenylalanine (BPA) or BPA alone were used as boron compounds. In all the treatment cases, the dose constraint was set to deliver a dose <10–12 Gy-eq to the skin or oral mucosa. There was a patient cohort of 62, with a median follow-up of 18.7 months (range, 0.7–40.8). A total of 87 BNCT procedures were performed. The overall response rate was 58% within 6 months after BNCT. The median survival time was 10.1 months from the time of BNCT. The 1- and 2-year overall survival (OS) rates were 43.1% and 24.2%, respectively. The major acute Grade 3 or 4 toxicities were hyperamylasemia (38.6%), fatigue (6.5%), mucositis/stomatitis (9.7%) and pain (9.7%), all of which were manageable. Three patients died of treatment-related toxicity. Three patients experienced carotid artery hemorrhage, two of whom had coexistent infection of the carotid artery. This study confirmed the feasibility of our dose-estimation method and that controlled trials are warranted. (author)

Ewing's sarcoma accounts for 4-6% of primary malignant bone tumors and it affects the head and neck in only 1-4% of cases. The purpose of this study was to review the NCI experience with Ewing's sarcoma of the head and neck in children. Patients and Methods: A retrospective analysis of patient files with head and neck Ewing's sarcoma treated at the National Cancer Institute, Cairo University, Egypt, during the period from 1997 to 2008 was done. Files were reviewed and data for patients, tumor and treatment profile were extracted. Results: Twenty patients out of 280 with Ewing's sarcoma were identified during an 11 -year period. Patients had a median age of 11.5 years (range 5 months - 22 years) with a male to female ratio of 1:1. The most common tumor site was in the mandible (9/20, 45%) followed by a neck mass (4/20, 20%) and a clavicular mass (3/20, 15%). Six patients (30%) were metastatic at presentation. Most of the patients (19/20, 95%) received chemotherapy. Local therapy was in the form of radical radiotherapy for 8 patients (40%), 2 patients (10%) had surgery alone, while five patients (25%) had surgical resection and postoperative radiotherapy. Overall survival ranged from 1 to 128 months, with a median of 36 months. At the end of the study, 9 patients (45%) were alive in CR, 6 (30%) were lost to FU in disease progression, while 5 patients died from disease progression. Conclusion: Ewing's sarcoma of the head and neck is a disease of a rare incidence with debate about the optimum local therapy. Small non-metastatic tumors with good response to chemotherapy have abetter outcome.

Purpose: Hemoglobin levels are currently the focus of interest as prognostic factors in patients with head and neck cancer. Most published clinical trials have confirmed hemoglobin to process a significant influence on survival in patients treated with radiotherapy. In our study we have investigated the prognostic value of hemoglobin in a combined modality schedule. Patients and Methods: Forty-three patients with advanced head and neck tumors were treated with combined radiochemotherapy. The therapy comprised 2 courses of induction chemotherapy with ifosfamide (1,500 mg/m 2 , day 1 to 5) and cisplatin (60 mg/m 2 , day 5) followed by hyperfractionated accelerated radiotherapy with a total dose of only 30 Gy. Surgery involved tumor resection and neck dissection. Results: The 1-year overall survival rate and the 2-year survival rate were 79% and 56%, respectively. The 1- and 2-year recurrence-free survival rates were 68% and 49%, respectively. Prognostic factors with an impact on survival were seen in tumor size (T3 vs T4, p=0.0088), response to radio-chemotherapy at the primary site (no vital tumor rest vs vital tumor rest, p=0.045), response to lymph node radio-chemotherapy (no vital tumor cells vs vital tumor cells, p=0.013) and level of hemoglobin after radio-chemotherapy (Hb≥11.5 g/dl vs [de

Full Text Available Introduction: Radiomics extracts and mines large number of medical imaging features in a non-invasive and cost-effective way. The underlying assumption of radiomics is that these imaging features quantify phenotypic characteristics of entire tumor. In order to enhance applicability of radiomics in clinical oncology, highly accurate and reliable machine learning approaches are required. In this radiomic study, thirteen feature selection methods and eleven machine learning classification methods were evaluated in terms of their performance and stability for predicting overall survival in head and neck cancer patients. Methods: Two independent head and neck cancer cohorts were investigated. Training cohort HN1 consisted 101 HNSCC patients. Cohort HN2 (n=95 was used for validation. A total of 440 radiomic features were extracted from the segmented tumor regions in CT images. Feature selection and classification methods were compared using an unbiased evaluation framework. Results: We observed that the three feature selection methods MRMR (AUC = 0.69, Stability = 0.66, MIFS (AUC = 0.66, Stability = 0.69, and CIFE (AUC = 0.68, Stability = 0.7 had high prognostic performance and stability. The three classifiers BY (AUC = 0.67, RSD = 11.28, RF (AUC = 0.61, RSD = 7.36, and NN (AUC = 0.62, RSD = 10.52 also showed high prognostic performance and stability. Analysis investigating performance variability indicated that the choice of classification method is the major factor driving the performance variation (29.02% of total variance. Conclusions: Our study identified prognostic and reliable machine learning methods for the prediction of overall survival of head and neck cancer patients. Identification of optimal machine-learning methods for radiomics based prognostic analyses could broaden the scope of radiomics in precision oncology and cancer care.

Purpose. - To report preliminary results of a prospective study of intensity-modulated radiotherapy (IMRT) for head and neck squamous cell carcinoma (HNC) with bilateral irradiation of the neck. Patients and methods. - At the Alexis Vautrin Cancer Center, 23 patients have been treated with IMRT for HNC since January 2002-August 2003. The first 10 patients with a minimum follow-up of 3 months were analyzed. All tumors were oropharyngeal. There were four females and six males, with a mean age of 50 years (range 39-66). Stages were I-II in eight and III-IV in two. CTV1 was microscopic disease and N0 neck (prescribed dose: 50 Gy) and CTV2 was macroscopic disease and the volume at risk (prescribed dose: 66-70 Gy). PTV were CTV + 5 mm. Patient's immobilization consisted of a five-point head neck shoulder thermoplastic mask. Set-up verifications were done by semi-automatically matching portal images and digitized reconstructed radiographs. IMRT used dynamic multi-leaf collimation. Five patients (group A) received 50 Gy IMRT (two post-operative and three with a brachytherapy boost with a mean dose: 27.5 Gy), and five patients (group B) received 66-70 Gy IMRT (four post-operative). Acute and late normal tissue effects were graded according to the RTOG-EORTC radiation morbidity scoring criteria. Results. - With a median follow-up of 7.4 months (range 3-18.5), no patient died or had loco-regional relapse. The displacements were <4 mm in 98% cases. CTV1 and 2 received 95% of the prescribed dose in 100% of the volume. On average the mean dose to the contralateral parotid was 25.5 Gy for group A vs. 31 Gy for group B (P = 0.09). Mean doses <26 Gy were obtained in three of five patients in group A vs. zero of five patients in group B (P = 0.04). Acute skin toxicities were grade 1 in five patients, grade 2 in four and grade 3 in one. Acute mucositis cases were grade 1 in three patients, grade 2 in five and localized grade 3 in two. At 3 months, 50% of the patients had a grade 0

Objective: To assess the diagnostic value of PET/MR (positron emission tomography/magnetic resonance imaging) with FDG (18F-fluorodeoxyglucose) for lymph node staging in head and neck cancer. Materials and methods: This prospective study was approved by the local ethics committee; all patients signed informed consent. Thirty-eight patients with squamous cell carcinoma of the head and neck region underwent a PET scan on a conventional scanner and a subsequent PET/MR on a whole-body hybrid system after a single intravenous injection of FDG. The accuracy of PET, MR and PET/MR for lymph node metastases were compared using receiver operating characteristic (ROC) analysis. Histology served as the reference standard. Results: Metastatic disease was confirmed in 16 (42.1%) of 38 patients and 38 (9.7%) of 391 dissected lymph node levels. There were no significant differences between PET/MR, MR and PET and MR (p > 0.05) regarding accuracy for cervical metastatic disease. Based on lymph node levels, sensitivity and specificity for metastatic involvement were 65.8% and 97.2% for MR, 86.8% and 97.0% for PET and 89.5% and 95.2% for PET/MR. Conclusions: In head and neck cancer, FDG PET/MR does not significantly improve accuracy for cervical lymph node metastases in comparison to MR or PET.

We report a case of upper airway obstruction after extubation in a 69-year-old female patient who underwent transurethral ureterolithotripsy (TUL). She had underwent bilateral modified radical neck dissection 7 years previously. TUL went smoothly in Trenderenburg position, and the extubation was performed after antagonism of neuromuscular block. The patient was closely observed in the operating theater, but about 10 minutes after extubation, she was noted to have dyspnea and tracheal tug. Dexamathasone 2 mg IV was given but was unsuccessful. Although we could support the airway with bag-mask ventilation, continuous stridor required re-intubation. Direct laryngoscopy revealed severe obstruction caused by laryngeal edema. An otolaryngologist was consulted and he performed tracheostomy. We transferred the patient to the intensive care unit for observation. Flexible fiberoptic scope examination performed on postoperative day (POD) 1 showed the decrease of the laryngeal edema. Tacheal tube was removed on POD 7 and she was discharged from the hospital POD 10 without further complications. Patients after a neck dissection may be at elevated risk for postoperative laryngeal edema caused by lymphatic destruction or venous congestion of the neck.

To investigate oral candidiasis in patients with head and neck cancer before, during, and after radiation therapy, and to explore its association with clinical oropharyngeal symptoms. A cohort study. University hospital. Subjects who received radiation therapy (RT) for the treatment of head and neck cancer were divided into two groups: an oral cavity irradiated group (OIRR group, n = 29) and an oral cavity nonirradiated group (ONIRR group, n = 17). A control group consisted of 18 healthy subjects. Patients were examined for signs of oral candidiasis before, during, immediately after, and one month after RT. Mouth and throat soreness (MTS), dysphagia, and xerostomia were evaluated by self-reported questionnaires, and associations between oral candidiasis and these symptoms were analyzed. The incidence of oral candidiasis during RT was significantly higher in the OIRR group (55.2%) than in the ONIRR group (11.8%). Similarly, the occurrence of xerostomia during RT was significantly higher in the OIRR group (86.2%) than in the ONIRR group (52.9%). In the OIRR group, the mean MTS score at the 20th fraction of RT was significantly higher in patients with candidiasis (mean +/- SD, 5.8 +/- 2.1) than in those with RT-induced mucositis without candidiasis (3.7 +/- 2.0). In the OIRR group, 65.2 percent of patients who experienced dysphagia developed oral candidiasis, compared with only 10 percent in the ONIRR group. Oral candidiasis concurrent with oral mucositis due to RT may increase oropharyngeal discomfort during RT. Copyright (c) 2010 American Academy of Otolaryngology-Head and Neck Surgery Foundation.

Health related quality of life information gives patients and carers an indication of how they will be affected following treatment. Such knowledge can promote realistic expectations and help patients come to terms with their outcome. The aim of this paper is to describe the background development of patient information sheets produced at our unit. The data were compiled using a common head and neck cancer specific quality of life questionnaire (University of Washington Quality of Life [UW-QOL]). There are 12 domains comprising activity, appearance, anxiety, chewing, mood, pain, recreation, saliva, shoulder, speech, swallowing and taste. The data were collected over 19 years at our unit and focus on follow-up records at around 2 years as this gives a good indication of health related quality of life in survivorship. UW-QOL questionnaires were available from 1,511 patients treated following primary diagnosis of head and neck cancer, and there were 24 subgroups based on cancer site, stage and treatment. There were 2 other subgroups: 132 having transoral laser resection and 176 having laryngectomy. The patient and carer research forum helped to design the information sheets, which display overall quality of life, percentages with 'good' outcome and 'significant problem' by domain, and the most important domains. Three examples are included in this paper: early stage oral cancer treated by surgery alone, early laryngeal cancer treated by surgery alone, and late stage oropharyngeal cancer treated by surgery and postoperative radiotherapy. All 26 subgroup information sheets are available in booklet form and on the internet. How the surgical community best utilises this type of resource needs further research.

To evaluate the feasibility of PET/MRI (positron emission tomography/magnetic resonance imaging) with FDG ({sup 18}F-fluorodeoxyglucose) for initial staging of head and neck cancer. The study group comprised 20 patients (16 men, 4 women) aged between 52 and 81 years (median 64 years) with histologically proven squamous cell carcinoma of the head and neck region. The patients underwent a PET scan on a conventional scanner and a subsequent PET/MRI examination on a whole-body hybrid system. FDG was administered intravenously prior to the conventional PET scan (267-395 MBq FDG, 348 MBq on average). The maximum standardized uptake values (SUV{sub max}) of the tumour and of both cerebellar hemispheres were determined for both PET datasets. The numbers of lymph nodes with increased FDG uptake were compared between the two PET datasets. No MRI-induced artefacts where observed in the PET images. The tumour was detected by PET/MRI in 17 of the 20 patients, by PET in 16 and by MRI in 14. The PET/MRI examination yielded significantly higher SUV{sub max} than the conventional PET scanner for both the tumour (p < 0.0001) and the cerebellum (p = 0.0009). The number of lymph nodes with increased FDG uptake detected using the PET dataset from the PET/MRI system was significantly higher the number detected by the stand-alone PET system (64 vs. 39, p = 0.001). The current study demonstrated that PET/MRI of the whole head and neck region is feasible with a whole-body PET/MRI system without impairment of PET or MR image quality. (orig.)

In cases of head and neck cancer, surgical advances in combination with radiotherapy (RT) have brought an increase in patients' probability of cure. RT is widely used and aims to destroy cancer cells in order to reduce or eliminate a malignant tumor. However, RT also causes major changes in patients' quality of life during and after treatment. The current study aims to evaluate the side effects of RT in patients with head and neck cancer and its influence on quality of life. The study population included head and neck cancer patients submitted to RT at the University of Sao Paulo Hospital in Ribeirao Preto, Brazil. Data were collected with the FACT H and N instrument and McMaster University's Questionnaire for head and neck RT and submitted to quantitative statistical analysis using SPSS (Statistical Package for the Social Sciences). The main side effects of RT that affected physical quality of life were related to salivation and nutritional problems, while the predominant emotional problems were depression and anxiety. (author)

The aim of this study was to investigate the risk factors for dysphagia induced by chemoradiotherapy for head and neck cancers. Forty-seven patients with head and neck cancers who underwent definitive chemoradiotherapy from December 1998 to March 2006 were reviewed retrospectively. Median age was 63 years (range, 16-81). The locations of the primary lesion were as follows: larynx in 18 patients, oropharynx in 11, nasopharynx in 7, hypopharynx in 7 and others in 4. Clinical stages were as follows: Stage II in 20 and Stages III-IV in 27. Almost all patients underwent platinum-based concomitant chemoradiotherapy. The median cumulative dose of cisplatin was 100 mg/m 2 (range, 80-300) and median radiation dose was 70 Gy (range, 50-70). Severe dysphagia (Grade 3-4) was observed in 22 patients (47%) as an acute toxic event. One patient required tube feeding even at 12-month follow-up. In univariate analysis, clinical stage (III-IV) (P=0.017), primary site (oro-hypopharynx) (P=0.041) and radiation portal size (>11 cm) (P<0.001) were found to be associated with severe dysphagia. In multivariate analysis, only radiation portal size was found to have a significant relationship with severe dysphagia (P=0.048). Larger radiation portal field was associated with severe dysphagia induced by chemoradiotherapy. (author)

Purpose: To determine if the addition of fluorodeoxyglucose positron emission tomography (FDG-PET) data changes primary site gross tumor volumes (GTVs) in head and neck cancers. Methods and Materials: Computed tomography (CT), contrast-enhanced CT, and FDG-PET-CT scans were obtained in 10 patients with head and neck cancers. Eight experienced observers (6 head and neck oncologists and 2 neuro-radiologists) with access to clinical and radiologic reports outlined primary site GTVs on each modality. Three cases were recontoured twice to assess intraobserver variability. The magnitudes of the GTVs were compared. Intra- and interobserver variability was assessed by a two-way repeated measures analysis of variance. Inter- and intraobserver reliability were calculated. Results: There were no significant differences in the GTVs across the image modalities when compared as ensemble averages; the Wilcoxon matched-pairs signed-rank test showed that CT volumes were larger than PET-CT. Observers demonstrated the greatest consistency and were most interchangeable on contrast-enhanced CT; they performed less reliably on PET-CT. Conclusions: The addition of PET-CT to primary site GTV delineation of head and neck cancers does not change the volume of the GTV defined by this group of expert observers in this patient sample. An FDG-PET may demonstrate differences in neck node delineation and in other disease sites

Purpose: Head and neck carcinomas that recur locally after conventional irradiation pose a difficult therapeutic problem. We evaluated safety and efficacy of boron neutron capture therapy (BNCT) in the treatment of such cancers. Methods and Materials: Twelve patients with inoperable, recurred, locally advanced (rT3, rT4, or rN2) head and neck cancer were treated with BNCT in a prospective, single-center Phase I-II study. Prior treatments consisted of surgery and conventionally fractionated photon irradiation to a cumulative dose of 56-74 Gy administered with or without concomitant chemotherapy. Tumor responses were assessed using the RECIST (Response Evaluation Criteria in Solid Tumors) criteria and adverse effects using the National Cancer Institute common toxicity grading v3.0. Intravenously administered boronophenylalanine-fructose (BPA-F, 400 mg/kg) was used as the boron carrier. Each patient was scheduled to be treated twice with BNCT. Results: Ten patients received BNCT twice; 2 were treated once. Ten (83%) patients responded to BNCT, and 2 (17%) had tumor growth stabilization for 5.5 and 7.6 months. The median duration of response was 12.1 months; six responses were ongoing at the time of analysis or death (range, 4.9-19.2 months). Four (33%) patients were alive without recurrence with a median follow-up of 14.0 months (range, 12.8-19.2 months). The most common acute adverse effects were mucositis, fatigue, and local pain; 2 patients had a severe (Grade 3) late adverse effect (xerostomia, 1; dysphagia, 1). Conclusions: Boron neutron capture therapy is effective and safe in the treatment of inoperable, locally advanced head and neck carcinomas that recur at previously irradiated sites

In this study, we investigated the consensus gene modules in head and neck cancer (HNC) and cervical cancer (CC). We used a publicly available gene expression dataset, GSE6791, which included 42 HNC, 14 normal head and neck, 20 CC and 8 normal cervical tissue samples. To exclude bias because of different human papilloma virus (HPV) types, we analyzed HPV16-positive samples only. We identified 3824 genes common to HNC and CC samples. Among these, 977 genes showed high connectivity and were used to construct consensus modules. We demonstrated eight consensus gene modules for HNC and CC using the dissimilarity measure and average linkage hierarchical clustering methods. These consensus modules included genes with significant biological functions, including ATP binding and extracellular exosome. Eigengen network analysis revealed the consensus modules were highly preserved with high connectivity. These findings demonstrate that HPV16-positive head and neck and cervical cancers share highly preserved consensus gene modules with common potentially therapeutic targets.

Prospective analysis was performed of self-reported and biochemically confirmed tobacco use in 50 head and neck cancer patients during treatment. With 93.5% compliance to complete weekly self-report and biochemical confirmatory tests, 29.4% of smokers required biochemical assessment for identification. Accuracy increased by 14.9% with weekly vs. baseline self-reported assessments. Data confirm that head and neck cancer patients misrepresent true tobacco use during treatment.

Copy number variations (CNSs) of large genomic regions are an important mechanism implicated in the development of head and neck cancer, however, for most changes their exact role is not well understood. The aim of this study was to find possible associations between gains/losses of genomic regions and clinically distinct subgroups of head and neck cancer patients. Array comparative genomic hybridization (aCGH) analysis was performed on DNA samples in 64 patients with cancer in oral cavity, oropharynx or hypopharynx. Overlapping genomic regions created from gains and losses were used for statistical analysis. Following regions were overrepresented: in tumors with stage I or II a gain of 2.98 Mb on 6p21.2-p11 and a gain of 7.4 Mb on 8q11.1-q11.23; in tumors with grade I histology a gain of 1.1 Mb on 8q24.13, a loss of a large part of p arm of chromosome 3, a loss of a 1.24 Mb on 6q14.3, and a loss of terminal 32 Mb region of 8p23.3; in cases with affected lymph nodes a gain of 0.75 Mb on 3q24, and a gain of 0.9 Mb on 3q26.32-q26.33; in cases with unaffected lymph nodes a gain of 1.1 Mb on 8q23.3, in patients not treated with surgery a gain of 12.2 Mb on 7q21.3-q22.3 and a gain of 0.33 Mb on 20q11.22. Our study identified several genomic regions of interest which appear to be associated with various clinically distinct subgroups of head and neck cancer. They represent a potentially important source of biomarkers useful for the clinical management of head and neck cancer. In particular, the PIK3CA and AGTR1 genes could be singled out to predict the lymph node involvement.

Full Text Available Aim: To study the long-term survival of dental implants placed in native or grafted bone in irradiated bone in subjects who had received radiation for head and neck cancer. Materials and Methods: A retrospective chart review was conducted for all patients who received dental implants following radiation treatment for head and neck cancer between May 1, 1987 and July 1, 2008. Only patients irradiated with a radiation dose of 50 Gy or greater and those who received dental implants in the irradiated field after head and neck radiation were included in the study. The associations between implant survival and patient/implant characteristics were estimated by fitting univariate marginal Cox proportional hazards models. Results: A total of 48 patients who had prior head and neck radiation had 271 dental implants placed during May 1987-July 2008. There was no statistically significant difference between implant failure in native and grafted bone (P=0.76. Survival of implants in grafted bone was 82.3% and 98.1% in maxilla and mandible, respectively, after 3 years. Survival of implants in native bone in maxilla and mandible was 79.8% and 100%, respectively, after 3 years. For implants placed in the native bone, there was a higher likelihood of failure in the maxilla compared to the mandible and there was also a tendency for implants placed in the posterior region to fail compared to those placed in the anterior region. Conclusion: There was no significant difference in survival when implants were placed in native or grafted bone in irradiated head and neck cancer patients. For implants placed in native bone, survival was significantly influenced by the location of the implant (maxilla or mandible, anterior or posterior.

It is very difficult to treat postoperative fistulas of head and neck cancer by irradiation and other preoperative therapy. We reviewed 179 patients with oral cancer, mesopharyngeal and hypopharyngeal cancer underwent reconstruction between 1994 and 2003. Our analysis reveals that the incidence of fistula is 18.4% and exposure dose is predisposing factor for fistula formation. We observed many fistulas in posterior of oral floor and pedicle flap more than free flap. There are 14 patients of surgical repair, we detected pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus (MRSA) in them. (author)

A total of 99 patients with head and neck cancer who were to undergo surgery were randomized in a prospective comparative study of sulbactam-ampicillin (1:2 ratio; four doses of 3 g of ampicillin and 1.5 g of sulbactam intravenously [i.v.] every 6 h) versus clindamycin (four doses of 600 mg i.v. every 6 h)-amikacin (two doses of 500 mg i.v. every 12 h) as prophylaxis starting at the induction of anesthesia. The two groups of evaluable patients (43 in the clindamycin-amikacin treatment group and 42 in the sulbactam-ampicillin treatment group) were comparable as far as age (mean, 57 years; range, 21 to 84 years), sex ratio (71 males, 28 females), weight (mean, 66 kg; range, 40 to 69 kg), indication for surgery (first surgery, 48 patients; recurrence, 37 patients), previous anticancer treatment (surgery, radiation therapy, chemotherapy), type of surgery, and stage of cancer. The overall infection rate (wound, bacteremia, and bronchopneumonia) within 20 days after surgery was 20 patients in each group. Wound infections occurred in 14 (33%) sulbactam-ampicillin-treated patients and 9 (21%) clindamycin-amikacin-treated patients (P = 0.19; not significant). The rates of bacteremia were 2 and 4%, respectively. The rates of bronchopneumonia were 14.3 and 23.2%, respectively (P was not significant). Most infections were polymicrobial, but strict anaerobes were recovered only from patients who received sulbactam-ampicillin. Antimicrobial treatment was required within 20 days after surgery for 42% of the sulbactam-ampicillin-treated patients and 44% of the clindamycin-amikacin-treated patients. By comparison with previous studies, we observed a decreased efficacy of antimicrobial prophylaxis in patients with head and neck cancer undergoing surgery because of the increased proportion of patients who were at very high risk for infection (extensive excision and plastic reconstruction in patients with recurrent stage III and IV cancers) and because of the longer duration of

Purpose Head and neck squamous cell carcinoma (HNSCC) is commonly treated with radiotherapy, and local failure after treatment remains the major cause of disease-related mortality. To date human papillomavirus (HPV) is the only known clinically validated, targetable biomarkers of response to radiation in HNSCC. Experimental Design We performed proteomic and transcriptomic analysis of targetable biomarkers of radioresistance in HPV-negative HNSCC cell lines in vitro, and tested whether pharmacologic blockade of candidate biomarkers sensitized cells to radiotherapy. Candidate biomarkers were then investigated in several independent cohorts of patients with HNSCC. Results Increased expression of several targets was associated with radioresistance, including FGFR, ERK1, EGFR, and focal adhesion kinase (FAK), also known as PTK2. Chemical inhibition of PTK2/FAK, but not FGFR, led to significant radiosensitization with increased G2/M arrest and potentiated DNA damage. PTK2/FAK overexpression was associated with gene amplification in HPV-negative HNSCC cell lines and clinical tumors. In two independent cohorts of patients with locally advanced HPV-negative HNSCC, PTK2/FAK amplification was highly associated with poorer disease-free survival (DFS) (P=0.012 and P=0.034). PTK2/FAK mRNA expression was also associated with worse DFS (P=0.03). Moreover, both PTK2/FAK mRNA (P=0.021) and copy number (P=0.063) were associated with DFS in the Head and Neck Cancer subgroup of The Cancer Genome Atlas. Conclusion Proteomic analysis identified PTK2/FAK overexpression is a biomarker of radioresistance in locally advanced HNSCC, and PTK2/FAK inhibition radiosensitized HNSCC cells. Combinations of PTK2/FAK inhibition with radiotherapy merit further evaluation as a therapeutic strategy for improving local control in HPV-negative HNSCC. PMID:27036135

Case-control studies show a possible relationship between oral bacteria and head and neck squamous cell cancer (HNSCC). Prospective studies are needed to examine the temporal relationship between oral microbiome and subsequent risk of HNSCC. To prospectively examine associations between the oral microbiome and incident HNSCC. This nested case-control study was carried out in 2 prospective cohort studies: the American Cancer Society Cancer Prevention Study II Nutrition Cohort (CPS-II) and the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO). Among 122 004 participants, 129 incident patient cases of HNSCC were identified during an average 3.9 years of follow-up. Two controls per patient case (n = 254) were selected through incidence density sampling, matched on age, sex, race/ethnicity, and time since mouthwash collection. All participants provided mouthwash samples and were cancer-free at baseline. Oral microbiome composition and specific bacterial abundances were determined through bacterial 16S rRNA gene sequencing. Overall oral microbiome composition and specific taxa abundances were compared for the case group and the control group, using PERMANOVA and negative binomial generalized linear models, respectively, controlling for age, sex, race, cohort, smoking, alcohol, and oral human papillomavirus-16 status. Taxa with a 2-sided false discovery rate (FDR)-adjusted P-value (q-value) <.10 were considered significant. Incident HNSCC. The study included 58 patient cases from CPS-II (mean [SD] age, 71.0 [6.4] years; 16 [27.6%] women) and 71 patient cases from PLCO (mean [SD] age, 62.7 [4.8] years; 13 [18.3%] women). Two controls per patient case (n = 254) were selected through incidence density sampling, matched on age, sex, race/ethnicity, and time since mouthwash collection. Head and neck squamous cell cancer cases and controls were similar with respect to age, sex, and race. Patients in the case group were more often current tobacco

The artifacts not only blur the CT images and lead to inaccuracies in diagnosis, but also make the delineation of anatomical structures intractable, which is important in image-guided intervention procedures. These artifacts obscure the underlying anatomy, leading to uncertainty in the delineation of the target volumes and compromising the integrity of the density representation that is crucial for accurate dose calculation. Because head and neck cancer patients tend to be over the age of 50 years, they constitute a group likely to have dental prostheses. This kind of side effects considerably disturbs the therapeutic procedure. Radiation scatter from high atomic number (Z) materials is established to cause both soft tissue and bony complications in the oral cavity, making scattered radiation an important factor in head and neck region radiotherapy planning. In this study, we carried out theoretical analysis of the metal artifact, that is, streak artifact and dark artifact, and also critical analysis of dosimetric effect which cause by dental implants in CT images of head and neck cancer patients with the genuine teeth and implants inserted humanoid phantom. The phantom provides a unique and useful tool in head and neck dosimetry research. It can be used in the development of new imaging instrumentation, image acquisition strategies, and image processing and reconstruction methods.

We analyzed 15 cases of head and neck cancer (13 out of 15 were squqmous cell cancer.) by Southern blotting to identify the possible tumor suppressor gene. Firstly we searched the chromosome 17p with pYNZ22, pMCT35.1 and p144D6. 5 out of 7 informative cases showed loss of heterozygosity implying the loss of tumor suppressor gene near those loci. Afterwards analysis of these 5 cases is needed to identify the presence of tumor suppressor genes and the oncogenetic mechanism. (Author)

From a cohort of 2400 patients who had been irradiated 19 to 48 years previously for benign diseases in the head and neck region a randomly selected group of 605 patients was selected and traced back. From the 360 patients alive, 257 were examined clinically and 49 were examined by questionnaire for radiation-induced skin tumors and radiodermatitis. In 21 patients, a total of 30 skin tumors were diagnosed. In 8 of 21 patients, 10 skin carcinomas were detected at recall. A dose-effect relationship of 40 carcinomas/10(4) persons/Gy for a median follow-up period of 41 years for the area exposed was calculated. The severity of radiodermatitis is associated with a higher prevalence of skin cancer. The number of radiation-induced skin cancers rises with the post-treatment time. Because of these late radiation effects, radiotherapy of benign skin lesions is contraindicated, especially now that other therapy modalities are available

The role of dentistry other than oral care in patients undergoing radiotherapy for head and neck cancer

Directory of Open Access Journals (Sweden)

2017-05-01

Full Text Available The usefulness of dental approaches, such as oral management, has gained recognition among patients treated for head and neck cancer. In particular, oral management plays a very important role before, during, and after treatment in patients undergoing radiotherapy, chemotherapy, or a combination of both. However, specialized dentistry knowledge and techniques that are useful for patients undergoing radiotherapy for head and neck cancer have yet to be reported. Therefore, in this review article, our aim is to introduce dental approaches in radiotherapy for patients with head and neck cancer that have been developed and are currently being used at our institute.

Although active tobacco smoking has been considered a major risk factor for head and neck cancer, few studies have evaluated environmental tobacco smoke (ETS) and its interaction with mutagen sensitivity on the risk of head and neck cancer. We investigated the relationship between ETS and head and neck cancer in a case-control study of 173 previously untreated cases with pathologically confirmed diagnoses of squamous cell carcinoma of the head and neck and 176 cancer-free controls at Memorial Sloan-Kettering Cancer Center between 1992 and 1994. A structured questionnaire was used to collect ETS exposure and other covariates including a history of active tobacco smoking and alcohol use. ETS measures include a history of ETS exposure at home and at workplace. The associations between passive smoking and head and neck cancer were analyzed by Mantel-Haenszel methods and logistic regression models. Additive and multiplicative models were used to evaluate effect modifications between ETS and mutagen sensitivity. The crude odds ratio (OR) for ETS exposure was 2.8 [95% confidence intervals (CI), 1.3-6.0]. Controlling for age, sex, race, education, alcohol consumption, pack-years of cigarette smoking, and marijuana use, the risk of squamous cell carcinoma of the head and neck was increased with ETS (adjusted OR, 2.4; 95% CI, 0.9-6.8). Dose-response relationships were observed for the degree of ETS exposure; the adjusted ORs were 2.1 (95% CI, 0.7-6.1) for those with moderate exposure and 3.6 (95% CI, 1.1-11.5) for individuals with heavy exposure (P for trend = 0.025), in comparison with those who never had ETS exposures. These associations and the dose-response relationships were still present when the analysis was restricted to nonactive smoking cases and controls (crude OR, 2.2; 95% CI, 0.6-8.4). Crude odds ratios were 1.8 for those with moderate ETS exposure and 4.3 for individuals with heavy ETS exposure among nonsmoking cases and controls (P for trend = 0.008). More

As nutrition support for head and neck cancer patients who receive chemoradiotherapy (CRT) and whose oral cavity or pharynx is exposed to radiation, we perform percutaneous endoscopic gastrostomy (PEG) tube placement. We examined 235 patients who underwent PEG in our division between January 2003 and December 2009. For 64% of them, the purpose of performing PEG was nutrition support for CRT, of whom 74% actually used the tube. However, the situation varied according to the primary sites of patients. Forty-four percent of laryngeal cancer patients who underwent PEG actually used the tube, which was a significantly lower rate than others. Also, 81% of them removed the PEG tube within one year. These findings suggest that PEG-tube placement for nutrition support is not indispensable for all CRT cases. Therefore, we recommend performing PEG for oral, oropharyngeal, and hypopharyngeal cancer patients. (author)

We have been providing oral care for patients with head and neck cancer in Hokkaido University Hospital since 2007. In this paper, we report clinical statistics of the 254 head and neck cancer patients who received oral care. About 80 percent of these patients were treated with radiation therapy, so it is important to cope with adverse events related to such therapy. Oral care is helpful for cancer patients when it is started as soon as possible (at least 1 week before radiation therapy is started). The percentage of patients who could start oral care 4 days before radiation therapy gradually increased to about 60 percent by fiscal 2009. In fiscal 2010, the percentage decreased to its lowest level of 37.9 percent. To start oral care for all patients 7 days before irradiation, we are going to change our system and start oral care in the outpatient period. In their hometowns, oral care was continued for only 19 (27.0 percent) of the 74 patients who could not visit our hospital. An important task for our project is to establish a medical cooperation system for discharged patients treated for head and neck cancer. (author)

Purpose: To analyze outcomes after radiation therapy for head-and-neck cancer among a cohort of patients with human immunodeficiency virus (HIV). Methods and Materials: The medical records of 12 patients with serologic evidence of HIV who subsequently underwent radiation therapy to a median dose of 68 Gy (range, 64-72 Gy) for newly diagnosed squamous cell carcinoma of the head and neck were reviewed. Six patients (50%) received concurrent chemotherapy. Intensity-modulated radiotherapy was used in 6 cases (50%). All patients had a Karnofsky performance status of 80 or 90. Nine patients (75%) were receiving antiretroviral therapies at the time of treatment, and the median CD4 count was 460 (range, 266-800). Toxicity was graded according to the Radiation Therapy Oncology Group / European Organization for the Treatment of Cancer toxicity criteria. Results: The 3-year estimates of overall survival and local-regional control were 78% and 92%, respectively. Acute Grade 3+ toxicity occurred in 7 patients (58%), the most common being confluent mucositis (5 patients) and moist skin desquamation (4 patients). Two patients experienced greater than 10% weight loss, and none experienced more than 15% weight loss from baseline. Five patients (42%) experienced treatment breaks in excess of 10 cumulative days, although none required hospitalization. There were no treatment-related fatalities. Conclusions: Radiation therapy for head-and-neck cancer seems to be relatively well tolerated among appropriately selected patients with HIV. The observed rates of toxicity were comparable to historical controls without HIV.

1999-01-01

Purpose: To address outcomes in clinically asymptomatic patients in whom the unexpected finding of microscopic perineural invasion is noted at the time of surgery. Methods and Materials: The 35 patients included in this study had skin cancers of the head and neck treated with curative intent between January 1965 and April 1995 at the University of Florida. All patients were without clinical or radiographic evidence of perineural invasion but, at the time of biopsy or surgical excision, had the incidental finding of microscopic perineural invasion. Definitive therapy consisted of radiotherapy alone after lesion biopsy (3 patients) or surgical excision preceded (2 patients) or followed (30 patients) by radiotherapy. All patients had follow-up for at least 1 year, 13 patients (37%) had follow-up for at least 5 years. Results: The 5-year local control rate was 78%. The 5-year local control rate for the few patients treated with radiotherapy alone was statistically similar to that for patients treated with surgery and radiotherapy (100% vs. 77%, p = 0.4). Multivariate analysis for factors affecting local control included sex, histology, age, treatment group, clinical T stage, initial histologic differentiation, and previously untreated vs. recurrent tumors, none of which was found to be significant. Conclusions: Both surgery plus radiotherapy and radiotherapy alone provide a relatively high rate of local control for patients with incidentally discovered perineural invasion secondary to skin cancer

Photodynamic therapy in head and neck cancer

Directory of Open Access Journals (Sweden)

Kamil H Nelke

2014-02-01

Full Text Available Photodynamic therapy (PDT is a special type of treatment involving the use of a photosensitizer or a photosensitizing agent along with a special type of light, which, combined together, induces production of a form of oxygen that is used to kill surrounding cells in different areas of the human body. Specification of the head and neck region requires different approaches due to the surrounding of vital structures. PDT can also be used to treat cells invaded with infections such as fungi, bacteria and viruses. The light beam placed in tumor sites activates locally applied drugs and kills the cancer cells. Many studies are taking place in order to invent better photosensitizers, working on a larger scale and to treat deeply placed and larger tumors. It seems that PDT could be used as an alternative surgical treatment in some tumor types; however, all clinicians should be aware that the surgical approach is still the treatment of choice. PDT is a very accurate and effective therapy, especially in early stages of head and neck squamous cell carcinomas (HNSCC, and can greatly affect surgical outcomes in cancerous patients. We present a detailed review about photosensitizers, their use, and therapeutic advantages and disadvantages.

1999-01-01

Background: In patients with loco-regionally advanced head and neck cancer conventionally fractionated radiotherapy alone results in poor loco-regional control and survival rates. Treatment intensification by simultaneous administration of cytotoxic drugs produces higher acute morbidity. Therefore chemical radioprotection of normal tissues may be of clinical benefit. Patients and Methods: In a pilot study patients with advanced nonresectable head neck cancer treated with conventionally fractionated radical radiotherapy (60 to 66 Gy total doses) and concomitantly given 5-fluorouracil as protracted venous infusion, 250 mg/sqm/24 h over the entire treatment period were given amifostine 300 mg absolutely before each fraction. Acute treatment related mobidity was scored according to CTC classification and loco-regional control and survival rates were estimated. Comparison was made with a historical control group of identical chemoradiation but without amifostine application. Results: Chemoradiation induced oral mucositis was delayed and showed significant lower degrees at all 10 Gy increments (p 0.05). No significant toxicity was recorded with respect to blood pressure, serum calcium, potassium, hematologic parameters, emesis, nausea or body weight loss. Progression free survival and overall survival probability at 2 years were not statistically different in both cohorts. Conclusion: Amifostine given before each fraction of radiotherapy over 6 weeks has no cumulative toxicity, was well tolerated and may reduce treatment induced oral mucositis. No tumor protective effect was observed. (orig.) [de

A 52-year-old man presenting with progressive tetraplegia and dysesthsia over a period of 2 weeks was initially diagnosed as cervical myelitis. However, MRI taken 10 days later revealed bilateral paramedian medullary infarction. CT angiography showed calcification of bilateral vertebral arteries located within the field irradiated for superior pharyngeal cancer 14 years previously. Radiation therapy can facilitate atherosclerotic changes and the incidences of cerebral infarction increase after head and neck irradiation. Clinicians need to be aware that bilateral paramedian medullary infarction can occur after irradiation of the head and neck. Clinical manifestations can be similar to cervical myelitis with subacute progressive course. (author)

The aim of this study was to evaluate nutritional status, food intake, and dysphagia in long-term head and neck cancer survivors. Thirty-two patients with stage III-IV head and neck cancer treated by chemoradiotherapy were invited to evaluate nutritional status (malnutrition, relative weight loss), food intake (food modification; quality), and dysphagia. At a median follow up of 44 months, 6 of 32 patients were at risk for malnutrition. Women (p = .049) and patients with high body mass index before treatment (p = .024) showed more weight loss. None of the 32 patients could eat a "full diet." Six patients used nutritional supplements/tube feeding. Low dysphagia-related quality of life scores were significantly correlated to increased food modification (r = 0.405; p = .024). Nutritional advice in patients with head and neck cancer is still necessary years after chemoradiation and should focus on nutritional status, food modification, and quality, in accord with recommended food groups.

Analysis of the frequency and degree of temporomandibular disorder in patients with head and neck cancer undergoing radiotherapy

Directory of Open Access Journals (Sweden)

Douglas Roberto Pegoraro

Full Text Available Abstract Introduction: Head and neck cancer is responsible for an increasing incidence of primary malignant neoplasm cases worldwide. Radiotherapy is one of the treatments of choice for this type of cancer, but it can cause adverse effects, such as temporomandibular disorder. The objective of this study was to characterize the degree and frequency of temporomandibular disorder in patients with head and neck cancer undergoing radiotherapy. Method: This research was quantitative, descriptive and exploratory. The sample consisted of 22 patients that answered assessment questions and the Helkimo anamnestic questionnaire, modified by Fonseca (1992. The data were collected from May to October 2014, and statistically analyzed using the Chi-square test, with a significance level of p ≤ 0.05. Results: Of the 22 patients, 86.4 % were male, with a mean age of 58.86 ± 9.41 years. Temporomandibular disorder was present in 31.8% of the subjects, based on the assessment prior to radiotherapy, and in 59.1% in the post-treatment assessment. Among all questions, the most frequent was "Do you use only one side of the mouth to chew?" with 22.7% "yes" answers, both at the first assessment and at the post treatment. Conclusion: According to the results of this study, temporomandibular disorder is a disease that is present with a high prevalence in people diagnosed with head and neck cancer undergoing radiotherapy.

Introduction: The purpose of this study was to evaluate the clinical efficacy in our daily practice, outside clinical trials, of cetuximab plus radiotherapy in a majority of treatment-naive patients with locoregionally advanced head and neck squamous cell carcinomas. Methods: A retrospective study was performed to evaluate outcomes in patients who were treated definitively with cetuximab and radiotherapy (ExRT). Patients with stage III or IV, nonmetastatic, measurable squamous cell carcinoma of the head and neck (SCCHN) were eligible. Results: There were 18 males and two females. The median age was 61 years (range from 49 to 87 years old). Concurrent radiotherapy and cetuximab was used, in first line, in 17 patients with locally advanced disease; two patients with recurrent SCCHN, who were intolerant of Cisplatin-based regimens, were treated with radiotherapy combined with weekly cetuximab; and 1 patient received cetuximab and radiotherapy postoperatively. The median time of response was 10 months (range from 2 to 24 months). A partial response was observed in 11 cases; a complete response in nine cases. The occurrence of grade 2–3 skin toxicity was observed in 11 cases. Skin toxicity was clearly correlated with a better response and the duration of the response to the treatment. The use of cetuximab in combination with radiotherapy does not increase the side effects of radiotherapy. At the end of the follow-up, 17 patients died. Conclusion: Cetuximab, with its highly targeted mechanism of action and synergistic activity with current treatment modalities, is a valuable treatment option in head and neck patients. The effect of the epidermal growth factor receptor antagonist occurs without any change in the pattern and the severity of toxicity usually associated with head and neck radiation. Cetuximab seems not to provide the most benefit for patients with oropharyngeal cancers but will in patients with T4 tumors. However, the median duration of local control was

This study is a systematic analysis of the literature on psychosocial aspects in head and neck cancer patients. Patients with head and neck cancer experience a variety of physical as well as psychosocial problems. Physical problems include swallowing or chewing, speech and physical appearance. Psychosocial problems include anxiety, depression, loss of self-esteem and uncertainty about the future. Because of these problems, isolation from friends typically occurs, re-employment is difficult, and there are social and sexual tensions within families. Information and support by professionals, partners and/or fellow patients are related to positive rehabilitation outcomes such as the acquisition of speech, increases in constructive social functioning and decreases in depression.

The concept of using tumor genomic profiling information has revolutionized personalized cancer treatment. Head and neck (HN) cancer management is being influenced by recent discoveries of activating mutations in epidermal growth factor receptor and related targeted therapies with tyrosine kinase inhibitors, targeted therapies for Kristen Rat Sarcoma, and MET proto-oncogenes. Molecular imaging using PET plays an important role in assessing the biologic behavior of HN cancer with the goal of delivering individualized cancer treatment. This review summarizes recent genomic discoveries in HN cancer and their implications for functional PET imaging in assessing response to targeted therapies, and drug resistance mechanisms.

Cetuximab: its unique place in head and neck cancer treatment

Full Text Available Pol Specenier, Jan B Vermorken Department of Medical Oncology, Antwerp University Hospital, Edegem, Belgium Abstract: Head and neck cancer is the sixth most common cancer worldwide. At present, globally about 650,000 new cases of squamous cell carcinoma of the head and neck (SCCHN are diagnosed each year. The epidermal growth factor receptor (EGFR is almost invariably expressed in SCCHN. Overexpression of the EGFR is a strong and independent unfavorable prognostic factor in SCCHN. Cetuximab is a chimeric monoclonal antibody, which binds with high affinity to the extracellular domain of the human EGFR, blocking ligand binding, resulting in inhibition of the receptor function. It also targets cytotoxic immune effector cells towards EGFR-expressing tumor cells (antibody dependent cell-mediated cytotoxicity. The addition of cetuximab to radiotherapy (RT improves locoregional control and survival when compared to RT alone. The addition of cetuximab to platinum-based chemoradiation (CRT is feasible but does not lead to an improved outcome. Cetuximab plus RT has never been compared prospectively to CRT, which therefore remains the standard treatment for patients with locoregionally advanced SCCHN for whom surgery is not considered the optimal treatment, provided they can tolerate CRT. The addition of cetuximab to platinum-based chemotherapy prolongs survival in patients with recurrent or metastatic SCCHN. The combination of a platinum-based regimen and cetuximab should be considered as the standard first line regimen for patients who can tolerate this treatment.

To study protective role of pomegranate extract on radiation induced dermatitis and mucositis in head and neck cancer patients, a prospective, clinical, double blind case control study was carried out. 60 patients (30 active and controls) undergoing radiotherapy for head and neck cancer were studied for 12 months. Patients in study group were given whole fruit pomegranate extract. Each capsule contained 300 mg of whole fruit extract, each capsule contains 40% polyphenols and 27% punicalagin. Each patient was given 2 capsules every day for a period of 6 to 7 weeks. The skin and mucosal changes was graded according to the Acute Radiation Morbidity Scoring criteria (RTOG) for skin and mucous membrane. Among the 30 patients who received the pomegranate extract, 27 had grade 1, 2 had grade 2 and 1 had grade 3 dermatitis. Whereas those who did not receive the extract, 20 had grade 2 dermatitis, 7 had grade 3 dermatitis and 3 had grade 4 dermatitis. Among the 30 patients who received the pomegranate extract, 10 had grade 0, 17 had grade 1 and 3 had grade 2 mucositis. Whereas of those who did not receive the extract, 21 had grade 2 mucositis, 9 had grade 3 mucositis. The results were statistically significant. Our study is one of the first study in humans to demonstrate the effectiveness of pomegranate extract in preventing radiation dermatitis and mucositis. (author)

The purpose of this exploratory and descriptive study is to contribute to the sparse return-to-work literature on head and neck cancer (HNC) survivors. Interview participants were asked to reflect upon their work-related experience with cancer by answering two specific questions: (1) What advice would you give someone who has been newly diagnosed with head and neck cancer? (2) What advice would you give to employers of these people? Data were gathered through 10 individual semi-structured in-depth interviews with HNC clinic patients at a regional cancer center's head and neck clinic in Ontario, Canada. A constant comparative method of theme development was used. Codes identified in and derived from the data were discussed by research team members until consensus was reached. Codes with similar characteristics were grouped together and used to develop overarching themes. Work-related advice for peers focused on personal self-care and interactions within workplaces. Work-related advice to employers focused on demonstrating basic human values as well as the importance of communication. The study results suggest HNC clinic patients should be proactive with employers and help to set reasonable expectations and provide a realistic plan for work to be successfully completed. HNC clinic patients should develop communication skills to effectively disclose their cancer and treatment to employers. In this exploratory study, HNC clinic patients' advice was solution-focused underscoring the importance of self-care and pro-active communication and planning with employers. Employers were advised to demonstrate core human values throughout all phases of the work disability episode beginning at diagnosis.

2016-09-01

Full Text Available Background Hypomagnesemia is a common adverse event during cetuximab (Cmab treatment. However, few reports have investigated the incidence and risk factors of hypomagnesemia in head and neck cancer patients treated with Cmab. Methods We retrospectively reviewed 131 head and neck cancer patients who received Cmab-containing therapy. Main eligibility criteria were ≥3 Cmab administrations, no prior EGFR-directed therapy, and no prophylactic Mg supplementation.Results Median baseline serum Mg level and number of Cmab administrations were 2.2 mg/dl and eight, respectively. Overall incidence of hypomagnesemia was 50.4% (grade 1, 46.6%; grade 2, 3.1%; grade 3, 0%; grade 4, 0.8% and differed between patients treated with palliative chemotherapy and bioradiation (Cmab and radiation (63% vs. 24%; p<0.01. Independent risk factors were low baseline serum Mg [Odds ratio (OR 161.988, 95% confidence interval (CI 9.436-2780.895], ≥7 Cmab administrations (OR 3.56, 95% CI 1.16-13.98, and concurrent administration of platinum (cisplatin; OR 23.695, 95% CI 5.219-107.574, carboplatin; OR 5.487, 95% CI 1.831-16.439. Respective incidence of hypomagnesemia in patients in high- (concurrent platinum and ≥7 Cmab administrations and low-risk (no concurrent platinum and <7 Cmab administrations groups was 66.0% and 6.6% (P<0.001, OR 28.0. Conclusion Cmab is associated with a significant risk of hypomagnesemia in patients with head and neck cancer with longer term administration and concurrent platinum therapy. High-risk patients should be treated with particular care.

Femoral neck stress fractures are rare in healthy children, with only 9 cases previously reported. The present article reviews our institutional experience with femoral neck stress fractures in children younger than 10 years of age, to highlight the unique features of this condition. We undertook a retrospective review of clinical records of patients who had been treated at our institution for an idiopathic femoral neck stress fracture between 2000 and 2014. To focus on children rather than adolescents, the World Health Organization's definition of adolescent as a person between 10 and 19 years of age was used; we thereby limited our analysis to patients younger than 10 years of age. The study included 6 patients (3 males, 3 females) treated for an idiopathic femoral neck stress fracture, with a mean age at diagnosis of 7.7 years (range, 5.2 to 8.9 y). All patients presented with a limp, which worsened with activity and had persisted for a mean of 5 weeks (range, 2 to 9 wk). None of the patients had experienced an increase in activity level or sporting volume before symptom onset. On examination, 3 patients experienced pain with terminal hip flexion and 3 patients demonstrated pain-free hip range of motion. Plain radiography demonstrated inferior femoral neck cortical disruption, suggesting a compression-type stress fracture mechanism. The diagnosis was confirmed by cross-sectional imaging in all cases. All patients were initially treated with 6 to 8 weeks of non-weight-bearing followed by 4 to 6 weeks of partial weight-bearing, leading to complete healing in 4 patients. Two patients demonstrated incomplete healing and were managed with spica casting for an additional 6 weeks. Our case series illustrates the unique features of this rare condition in children, with a history and examination profile distinct from those of adolescents and adults. Compliance with weight-bearing restrictions is difficult in this population and hip spica casting may be required to permit

The purpose of this study was to analyze whether diffusion-weighted imaging (DWI) adds significant information to positron emission tomography/magnetic resonance imaging (PET/MRI) on lesion detection and characterization in head and neck cancers. Seventy patients with different head and neck cancers were enrolled in this prospective study. All patients underwent sequential contrast-enhanced (ce) PET/computed tomography (CT) and cePET/MRI using a tri-modality PET/CT-MR setup either for staging or re-staging. First, the DWI alone was evaluated, followed by the PET/MRI with conventional sequences, and in a third step, the PET/MRI with DWI was evaluated. McNemar's test was used to evaluate differences in the accuracy of PET/MRI with and without DWI compared to the standard of reference. One hundred eighty-eight (188) lesions were found, and of those, 118 (62.8 %) were malignant and 70 (37.2 %) were benign. PET/MRI without DWI had a higher accuracy in detecting malignant lesions than DWI alone (86.8 % vs. 60.6 %, p < 0.001). PET/MRI combined with DWI detected 120 concurrent lesions (89 malignant and 31 benign), PET/MRI alone identified 48 additional lesions (20 malignant and 28 benign), and DWI alone detected 20 different lesions (nine malignant and 11 benign). However, lesions detected on DWI did not change overall staging. SUV maximum and mean were significantly higher in malignant lesions than in benign lesions. DWI parameters between malignant and benign lesions were not statistically different. The use of DWI as part of PET/MRI to evaluate head and neck cancers does not provide remarkable information. Thus, the use of DWI might not be needed in clinical PET/MRI protocols for the staging or restaging of head and neck cancers. (orig.)

To investigate the long-term follow-up (5 years) of implementing patient-reported outcome measures (PROMs) in clinical practice to monitor health-related quality of life (HRQOL) in head and neck cancer (HNC) patients. A mixed method design was used. The usage rate of OncoQuest (a touch screen computer system to monitor HRQOL) and the subsequent nurse consultation was calculated among HNC patients who visited the outpatient clinic for regular follow-up, as well as differences between ever users and never users (sociodemographic and clinical characteristics). The content of the nurse consultation was investigated. Reasons for not using (barriers) or using (facilitators) OncoQuest and the nurse consultation were explored from the perspective of HNC patients, and of head and neck surgeons. Usage rate of OncoQuest was 67% and of the nurse consultation 79%. Usage of OncoQuest was significantly related to tumor subsite and tumor stage. Topics most frequently (>40%) discussed during the nurse consultation were global quality of life (97%), head and neck cancer related symptoms (82%), other physical symptoms such as pain (61%), and psychological problems such as anxiety (44%). Several barriers and facilitators to implement PROMs in clinical practice were reported by both patients and head and neck surgeons. Usage of PROMs in clinical practice and a nurse consultation is durable, even 5 years after the introduction. This study contributes to better insight into long-term follow-up of implementation, thereby guiding future research and projects that aim to implement PROMs in clinical practice to monitor HRQOL among (head and neck) cancer patients.

Purpose: Minimal literature exists with 10-year data on neck control in advanced head and neck cancer. The purpose of this study is to determine long-term regional control for base of tongue carcinoma patients treated with primary radiation therapy plus neck dissection. Methods and Materials: Between 1981-1996, primary radiation therapy was used to treat 68 patients with squamous cell carcinoma of the base of tongue. Neck dissection was added for those who presented with palpable lymph node metastases. The T-stage distribution was T1, 17; T2, 32; T3, 17; and T4, 2. The N-stage distribution was N0, 10; N1, 24; N2a, 6; N2b, 11, N2c, 8; N3, 7; and Nx, 2. Ages ranged from 35 to 77 (median 55 years) among the 59 males and nine females. Therapy generally consisted of initial external beam irradiation to the primary site (54 Gy) and neck (50 Gy). Clinically positive necks were boosted to 60 Gy with external beam irradiation. Three weeks later, the base of tongue was boosted with an Ir-192 interstitial implant (20-30 Gy). A neck dissection was done at the same anesthesia for those who presented with clinically positive necks, even if a complete clinical neck response was achieved with external beam irradiation. Neoadjuvant cisplatin-based chemotherapy was administered to nine patients who would have required a total laryngectomy if their primary tumors had been surgically managed. The median follow-up was 36 months with a range from 1 to 151 months. Eleven patients were followed for over 8 years. No patients were lost to follow-up. Results: Actuarial 5- and 10-year neck control was 96% overall, 86% after radiation alone, and 100% after radiation plus neck dissection. Pathologically negative neck specimens were observed in 70% of necks dissected after external beam irradiation. The remaining 30% of dissected necks were pathologically positive. These specimens contained multiple positive nodes in 83% despite a 56% overall complete clinical neck response rate to irradiation

We evaluated the usefulness of simultaneous intra-arterial chemotherapy and radiotherapy for oropharyngeal cancer without neck metastasis. Fifty eight cases without neck metastasis out of previously untreated 117 patients with oropharyngeal cancer treated at National Kyushu Cancer Center from 1972 to 1995 were examined. Seventeen patients were in T1, 27 in T2, 10 in T3, 4 in T4. Fourteen patients of 58 patients were treated by simultaneous intra-arterial chemotherapy and radiation therapy. The 5-year survival rate by Kaplan-Meier method for intra-arterial infusion group and non intra-arterial infusion group were 86% and 71%, respectively. Thirty one patients were treated with irradiation without surgery. In 31 cases without surgery, the 5-year survival rate for intra-arterial infusion group (13 cases) was 85%, while that for non intra-arterial infusion group (18 cases) was 60%, and the local control rate for intra-arterial infusion group is 92%, while that for non intra-arterial infusion group was 56%. Simultaneous intra-arterial chemotherapy and radiotherapy for oropharyngeal cancer without neck metastasis is useful to improve the prognosis with preserving the function. (author)

2012-01-01

Background: This analysis was undertaken to assess the need for planned neck dissection in patients with a complete response (CR) of involved nodes after irradiation and to determine the benefit of a neck dissection in those with less than CR by tumor site. Methods: Our cohort included 880 patients with T1-4, N1-3M0 squamous cell carcinoma of the oropharynx, larynx, or hypopharynx who received treatment between 1994 and 2004. Survival curves were calculated by the Kaplan-Meier Method, comparisons of rates with the log–rank test and prognostic factors by Cox's proportional hazard model. Results: Nodal CR occurred in 377 (43%) patients, of whom 365 patients did not undergo nodal dissection. The 5-year actuarial regional control rate of patients with CR was 92%. Two hundred sixty-eight of the remaining patients (53%) underwent neck dissections. The 5-year actuarial regional control rate for patients without a CR was 84%. Those who had a neck dissection fared better with 5-year actuarial regional control rates of 90% and 76% for those operated and those not operated (p < 0.001). Variables associated with poorer regional control rates included higher T and N stage, non-oropharynx cancers, non-CR, both clinical and pathological. Conclusions: With 92% 5-year neck control rate without neck dissection after CR, there is little justification for systematic neck dissection. The addition of a neck dissection resulted in higher neck control after partial response though patients with viable tumor on pathology specimens had poorer outcomes. The identification of that subgroup that benefits from additional treatment remains a challenge.

The glutathione (GSH), thioredoxin (Trx), and Nrf2 systems represent a major defense against reactive oxygen species (ROS), the cellular imbalance of which in cancer promotes growth and therapeutic resistance. This study investigated whether targeting the GSH, Trx, and Nrf2 antioxidant systems effectively eliminated head and neck cancer (HNC). At high concentrations, auranofin, but not buthionine sulfoximine (BSO) alone, decreased the viability of HNC, whereas even at low concentrations, auranofin plus BSO synergized to kill HNC cells. Dual silencing of the genes for GCLM and TrxR1 induced GSH depletion, Trx activity inhibition, and ROS accumulation, synergistically killing HNC cells. Inhibition of the GSH and Trx systems resulted in activation of the Nrf2-antioxidant response element (ARE) pathway, which may result in suboptimal GSH and Trx inhibition where HNC is resistant. Genetic inhibition of Nrf2 and/or HO-1 or trigonelline enhanced growth suppression, ROS accumulation, and cell death from GSH and Trx inhibition. The in vivo effects of GSH, Trx, and Nrf2 system inhibition were confirmed in a mouse HNC xenograft model by achieving growth inhibition >60% compared with those of control. Innovations: This study is the first to show that triple inhibition of GSH, Trx, and Nrf2 pathways could be an effective method to overcome the resistance of HNC. Inhibition of the Nrf2-ARE pathway in addition to dual inhibition of the GSH and Trx antioxidant systems can effectively eliminate resistant HNC. Antioxid. Redox Signal. 27, 106-114.

Pinatti, L M; Walline, H M; Carey, T E

2018-06-01

We conducted a critical review of human papillomavirus (HPV) integration into the host genome in oral/oropharyngeal cancer, reviewed the literature for HPV-induced cancers, and obtained current data for HPV-related oral and oropharyngeal cancers. In addition, we performed studies to identify HPV integration sites and the relationship of integration to viral-host fusion transcripts and whether integration is required for HPV-associated oncogenesis. Viral integration of HPV into the host genome is not required for the viral life cycle and might not be necessary for cellular transformation, yet HPV integration is frequently reported in cervical and head and neck cancer specimens. Studies of large numbers of early cervical lesions revealed frequent viral integration into gene-poor regions of the host genome with comparatively rare integration into cellular genes, suggesting that integration is a stochastic event and that site of integration may be largely a function of chance. However, more recent studies of head and neck squamous cell carcinomas (HNSCCs) suggest that integration may represent an additional oncogenic mechanism through direct effects on cancer-related gene expression and generation of hybrid viral-host fusion transcripts. In HNSCC cell lines as well as primary tumors, integration into cancer-related genes leading to gene disruption has been reported. The studies have shown that integration-induced altered gene expression may be associated with tumor recurrence. Evidence from several studies indicates that viral integration into genic regions is accompanied by local amplification, increased expression in some cases, interruption of gene expression, and likely additional oncogenic effects. Similarly, reported examples of viral integration near microRNAs suggest that altered expression of these regulatory molecules may also contribute to oncogenesis. Future work is indicated to identify the mechanisms of these events on cancer cell behavior.

Background and purpose: Anorexia is a common problem in cancer patients who receive radiotherapy. In this current study, we attempt to determine the effect of megestrol acetate and prepulsid on appetite and nutritional improvement in patients with head and neck cancers undergoing radiotherapy. Materials and Methods: One hundred twenty-nine consecutive patients with head and neck cancers treated between July 1993 and June 1994 were prospectively randomized to receive either megestrol acetate, 40 mg qid (megace group), prepulsid, 5 mg tid (cisapride group), or a placebo treatment (control group) during radiotherapy. Before radiotherapy, body weight (kg), appetite score, performance status, biochemical parameters and hematological parameters were evaluated, and the above-noted clinical and biochemical parameters were assessed and recorded every other week. All patients received 6- 10 MV X-rays or Co-60 γ-ray to head and neck region for a full course of radiotherapy, 61.2-75.6 Gy/7-9 weeks. Results: Forty-eight patients were enrolled in the megace group, 41 patients in the cisapride group, and 40 patients in the control group. At the 2nd, 4th, 6th and 8th week, as the radiation dose escalated, the megace group had significantly less body weight loss than did the cisapride and control groups (P = 0.045, 0.024, 0.006, 0.003, respectively). The appetite scores of the megace group were significantly higher than those of the cisapride and control groups (P 0.0001). However, there were no statistically significant differences in the change of albumin level among these three groups at the 2nd, 4th, 6th and 8th week (P > 0.05, respectively). Conclusions: Megestrol acetate can significantly decrease the degree of body weight loss, and can prevent the deterioration of appetite in patients with head and neck cancers receiving radiotherapy. However, prepulsid lacks the above-mentioned clinical benefits

Evidence suggests that rehabilitation interventions can improve function and quality of life in survivors of head and neck cancer (HNC), but there is a lack of coordinated, integrated services, and those offered are inconsistent. To address these gaps, we will develop and conduct preliminary evaluation of a rehabilitation consult, built on the theoretical foundations of goal setting and self-management, and composed of a brief functional evaluation, a resource compendium, and collaborative goal-setting and action planning processes. The development of the rehabilitation consult will be guided by intervention mapping, which consists of six steps: 1. Needs assessment; 2. Definition of program objectives; 3. Selection of theory-based intervention methods; 4. Production and pretesting; 5. Adoption, implementation and sustainability planning; 6. Process and effect evaluation. Within the intervention mapping framework, an iterative process of constructing drafts and mini-evaluations with consumers and experts will be used, modifying the rehabilitation consult intervention until a version suitable for formal evaluation is established. The rehabilitation consult will then be evaluated using a prospective, mixed method, single group design with 30 survivors of head and neck cancer. Outcomes will be assessed pre- and post-intervention and at 6-month follow-up. Survivors of head and neck cancer have among the most complex rehabilitation needs of all cancer patients. The rehabilitation consult is expected to improve knowledge and uptake of rehabilitation resources and strategies in survivors of head and neck cancer and thereby improve long-term function and quality of life. If the rehabilitation consult is effective in cancer patients with such high and diverse needs, this project will produce a toolkit that will be adaptable for other types of cancer in other jurisdictions.

EVIDENCE OF EPSTEIN-BARR VIRUS ASSOCIATION WITH HEAD AND NECK CANCERS: A REVIEW.

Science.gov (United States)

Prabhu, Soorebettu R; Wilson, David F

2016-01-01

Epstein-Barr virus (EBV) is ubiquitous: over 90% of the adult population is infected with this virus. EBV is capable of infecting both B lymphocytes and epithelial cells throughout the body including the head and neck region. Transmission occurs mainly by exchange of saliva. The infection is asymptomatic or mild in children but, in adolescents and young adults, it causes infectious mononucleosis, a self-limiting disease characterized by lethargy, sore throat, fever and lymphadenopathy. Once established, the virus often remains latent and people become lifelong carriers without experiencing disease. However, in some people, the latent virus is capable of causing malignant tumours, such as nasopharyngeal carcinoma and various B- and T-cell lymphomas, at sites including the head, neck and oropharyngeal region. As lymphoma is the second-most common malignant disease of the head, neck and oral region after squamous cell carcinoma, oral health care workers including dentists and specialists have a responsibility to carry out a thorough clinical examination of this anatomical region with a view to identifying and diagnosing lesions that may represent lymphomas. Early detection allows early treatment resulting in better prognosis. The focus of this review is on the morphology, transmission and carcinogenic properties of EBV and clinical and diagnostic aspects of a range of EBV-associated malignancies occurring in the head, neck and oral region. As carcinogenic agents, viruses contribute to a significant proportion of the global cancer burden: approximately 15% of all human cancers, worldwide, are attributable to viruses.1,2 Serologic and epidemiologic studies are providing mounting evidence of an etiologic association between viruses and head and neck malignancies.3 To update oral and maxillofacial surgeons and oral medicine specialists and raise awareness of this association, we recently reviewed the evidence of the etiologic role of human papillomavirus in oral disease.4

125 I seeds either individually placed or inserted into absorbable Vicryl suture carriers were utilized in conjunction with surgery and external beam radiotherapy in an attempt to increase local control rates in patients with advanced oropharyngeal and laryngopharyngeal cancers (T3-T4, N2-N3), massive cervical lymphadenopathy (N3) and an unknown primary site and locally recurrent head and neck cancers. Forty-eight patients were treated with 55 implants. The carotid artery was implanted in 15 patients, while seven patients had seeds inserted into the base of the skull region, and another three patients had implants near cranial nerves. Eighteen of the 48 patients were treated for cure. The actuarial survival at five years in this subgroup was 50%. The overall local control in the head and neck area was 58%. In this group no patients to date have had a local failure in the implanted volume. Seventeen patients with comparable stage of disease treated prior to 1974 with curative intent without 125 I implants were analyzed retrospectively for comparison with the implanted patients. The actuarial survival of these patients was 18% and the overall head and neck control was 21%. These differences are statistically significant at a P value of 0.01 and 0.007, respectively. Seventeen patients received implants for local recurrence. The local control in the head and neck area was 50%; however, the 2.5 year actuarial survival was only 17%. The complication rate was 11% (six of 55 implants). The improved survival, the high local control, and the minimal complication rates in this series makes the intraoperative implantation of 125 I seeds and effective adjunctive treatment to surgery and external beam irradiation

Cancer immunotherapy with NKT cells is a potential new treatment strategy for advanced head and neck cancer. NKT cell therapy is promising due to its unique anti-tumor activity and higher degree of safety compared to current therapies. Radiotherapy is indispensable as a standard treatment for advanced head and neck cancer. To elucidate the possibility of using NKT cells as an adjuvant immunotherapy with radiotherapy, we examined the effect of radiotherapy on NKT cells in patients with head and neck cancer. The number, IFN-gamma production and proliferation capacity of NKT cells were analyzed before and after 50 Gy radiation therapy in 12 patients with stage IV head and neck squamous cell carcinoma. The cytotoxic activity of NKT cells was examined in vitro. The number of NKT cells in the blood varied widely between patients. After radiation therapy, the population of CD3 T cells decreased significantly, while the NKT cell population remained stable. The number of NKT cells was the same after radiation therapy as before. IFN-gamma production from NKT cells collected just after radiotherapy was impaired after stimulation with exogenous ligand, but the proliferative responses of these NKT cells was enhanced in comparison to those collected before radiation therapy. Furthermore, the proliferated NKT cells displayed a significant level of anti-tumor activity. NKT cells are relatively resistant to radiation and might therefore be suitable for adjuvant immunotherapy to eradicate remnant cancer cells in patients who have undergone radiation therapy.

Mouth and pharyngeal cancers account for approximately 6% of cancers worldwide. Radiotherapy is one of the means of treatment of head and neck cancer. Consultation with a dental team experienced in caring for patients undergoing treatment for head and neck cancer will improve the quality of life of such patients. To evaluate the attitude of oncologists toward dental consultation to patients planning for/prior to/undergoing/post radiation therapy for head and neck cancers and to evaluate the number of radiation oncologists who encounter oral complaints and consider worth referring to a dentist. A questionnaire-based study was carried out following mailing of covering letter and self-administered questionnaire comprising 11 items, to 25 radiation oncology centers selected in India based on convenient sampling. Out of the 25 centers, we received response from 20 centers with 60 completely filled questionnaires. Five centers did not respond for further correspondences. The study indicated a need for awareness and education among radiation oncologists regarding dental consultation in patients planned/undergoing /post radiation therapy for head and neck cancer.

The emotional status of cancer patients is associated with disease course and treatment outcomes. In this study, the authors evaluated associations between the presence of pretreatment depression and pretreatment quality of life (QOL), nutritional status, and survival outcomes in patients with head and neck squamous cell carcinoma (HNSCC). For this prospective study, 241 patients with previously untreated HNSCC who underwent curative treatments were enrolled. Patients completed the Beck Depression Inventory (BDI)-II, the European Organization for Research and Treatment of Cancer (EORTC) 30-item Core QOL Questionnaire (QLQ-C30), and the EORTC QLQ Head and Neck Cancer module (QLQ-H&N35). EORTC QLQ scores were compared between depressive and nondepressive patients, as determined according to pretreatment BDI-II scores ≥ 14 and nutritional status and laboratory data. Pretreatment depression was present in 60 patients (24.9%). In depressive and nondepressive patients, the 3-year overall survival rates were 70.8% and 82.7%, respectively (P = .045), and the 3-year DFS rates were 63.5% and 79.1%, respectively (P = .015). After controlling for clinical factors, the presence of depression was predictive of 3-year DFS (P = .032). EORTC QLQ-C30 and QLQ-HN35 scores on all items except feeding tube, nutritional supplement, and problem with mouth opening differed between depressive and nondepressive patients (P nutritional status, and survival outcomes in patients with HNSCC. © 2015 American Cancer Society.

Purpose/Objective: To determine if intensity conformal modulated radiotherapy could diminish the radiation dose to the parotid gland in the treatment of primary head and neck cancer. Materials and Methods: The NOMOS Peacock treatment system was utilized in the planning and delivery of conformal radiotherapy for the following diseases: 1) an oropharyngeal cancer that extends from the soft palate to the tonsillar fossa without nodal disease, 2) laryngeal hypopharyngeal cancer without nodal disease, 3) and adenocystic carcinoma, that originated in the hard palate. Patients were treated to areas suspicious for microscopic disease (nodal disease in 1 and 2, perineural spread in 3) at 2 Gy per fraction for a tc of 50 Gy in five weeks. The primary disease was treated at 2.4 Gy per fraction for a total of 60 Gy over five weeks. The percent of the volume of each parotid gland receiving < 20 Gy, <25 Gy and <30 Gy retrospectively was determined for each of the above mentioned optimized plans. The patients were observed for the clinical development of xerostomia. Results: No patient developed clinically apparent xerostomia within one month of completion of radiotherapy. Conclusion: IMBXRT could reduce the volume to parotid glands receiving high radiation doses. Sparing of the parotid glands appear to be most easily accomplished when irradiating head and neck tumors that do not require regional nodal treatment. For head and neck cancer that requires nodal treatment it is possible to spare a significant portion of the parotid glands if the disease originates below the hyoid bone where the primary site is not in close proximity to the parotid glands. Objective salivary flow data are being obtained pre ar post treatment, to confirm the subjective impression of lack of clinical xerostomia. IMBXRT is potentially beneficial in decreasing the morbidity of xerostomia related to head and neck irradiation

Survivors of squamous cell carcinoma of the head and neck (HNSCC) are more severely affected in regard to affiliation to the work market than other cancer survivors. Few studies have investigated associations between socioeconomic and disease-related factors and work market affiliation after curative treatment of HNSCC. We investigated the factors for early retirement pension due to disability and unemployment in patients who had been available for work one year before diagnosis. In a nationwide, population-based cohort study, data on 2436 HNSCC patients treated curatively in 1992-2008 were obtained from the Danish Head and Neck Cancer Group database and linked to Danish administrative population-based registries to obtain demographic and socioeconomic variables. We used multivariate logistic regression models to assess associations between socioeconomic factors (education, income and cohabitating status), cancer-specific variables such as tumour site and stage, comorbidity, early retirement pension and unemployment, with adjustment for age, gender and year of diagnosis. Short education [odds ratio (OR) 4.8; 95% confidence interval (CI) 2.2-10.4], low income (OR 3.2; 95% CI 1.8-5.8), living alone (OR 3.0; 95% CI 2.1-4.4) and having a Charlson comorbidity index score of 3 or more (OR 5.9; 95% CI 3.1-11) were significantly associated with early retirement overall and in all site groups. For the subgroup of patients who were employed before diagnosis, the risk pattern was similar. Tumour stage was not associated with early retirement or unemployment. Cancer-related factors were less strongly associated with early retirement and unemployment than socioeconomic factors and comorbidity. Clinicians treating HNSCC patients should be aware of the socioeconomic factors related to work market affiliation in order to provide more intensive social support or targeted rehabilitation for this patient group.

Marijuana is the most commonly used illegal drug in the United States. In some subcultures, it is widely perceived to be harmless. Although the carcinogenic properties of marijuana smoke are similar to those of tobacco, no epidemiological studies of the relationship between marijuana use and head and neck cancer have been published. The relationship between marijuana use and head and neck cancer was investigated by a case-control study of 173 previously untreated cases with pathologically confirmed diagnoses of squamous cell carcinoma of the head and neck and 176 cancer-free controls at Memorial Sloan-Kettering Cancer Center between 1992 and 1994. Epidemiological data were collected by using a structured questionnaire, which included history of tobacco smoking, alcohol use, and marijuana use. The associations between marijuana use and head and neck cancer were analyzed by Mantel-Haenszel methods and logistic regression models. Controlling for age, sex, race, education, alcohol consumption, pack-years of cigarette smoking, and passive smoking, the risk of squamous cell carcinoma of the head and neck was increased with marijuana use [odds ratio (OR) comparing ever with never users, 2.6; 95% confidence interval (CI), 1.1-6.6]. Dose-response relationships were observed for frequency of marijuana use/day (P for trend marijuana use (P for trend marijuana use were observed with cigarette smoking, mutagen sensitivity, and to a lesser extent, alcohol use. Our results suggest that marijuana use may increase the risk of head and neck cancer with a strong dose-response pattern. Our analysis indicated that marijuana use may interact with mutagen sensitivity and other risk factors to increase the risk of head and neck cancer. The results need to be interpreted with some caution in drawing causal inferences because of certain methodological limitations, especially with regard to interactions.

It is estimated that more than 90% of head and neck cancer (HNC) survivors who underwent chemoradiotherapy experience one or more nutrition impact symptoms (NIS) in the months or years thereafter. Despite the high prevalence, there is limited research addressing long-term impact of NIS on outcomes such as nutrition and quality of life in HNC survivors treated with chemoradiotherapy. To conduct a systematic review of the literature pertaining to the presence of nutrition impact symptoms and their associated outcomes in post-chemoradiotherapy head and neck cancer survivors. A systematic review was conducted across three databases according to PRISMA guidelines and used to identify current literature regarding NIS in HNC survivors. A keyword search was conducted in PubMed, Scopus, and Web of Science from 2007 to 2017. Studies that met all of the following criteria were included in the review: (1) studies must include human subjects with a HNC diagnosis; (2) study participants must have received chemoradiotherapy; (3) study participants must have been post-treatment for a minimum of 3 months at the time of data collection; (4) full-text articles must have appeared in peer-reviewed journals; (5) papers must have been published in English; (6) studies must be quantitative in nature; (7) studies must have reported at least one NIS; and (8) studies must address at least one of the following outcomes: nutrition, functional status, or quality of life. Two independent reviewers assessed study quality using a predefined set of criteria. A systematic search yielded 1119 papers, of which 15 met the inclusion criteria. The study reviewed existing evidence of NIS in a variety of HNC survivors ranging from 3 months to greater than 10 years post-chemoradiotherapy treatment. Eight hundred forty-nine study participants were included in the review. Of the 15 studies, 10 were designed as prospective cohort studies, 4 were cross-sectional studies, and 1 was a retrospective cohort

Human papilloma virus: a new risk factor in a subset of head and neck cancers.

Bisht, Manisha; Bist, Sampan Singh

2011-01-01

Head and neck cancer is the sixth most common malignancy worldwide. Tobacco smoking and alcohol consumption are two well known behavioral risk factors associated with head and neck cancer. Recently, evidence is mounting that infection with human papilloma virus, most commonly human papilloma virus-16 is responsible for a subset of head and neck squamous cell carcinoma especially tumors of tonsillar origin. The molecular pathway used by human papilloma virus to trigger malignant transformation of tissue is different from that of other well known risk factors, i.e. smoking and alcohol, associated with squamous cell carcinoma. Apparently, these subsets of patients with human papilloma virus positive tumor are more likely to have a better prognosis than human papilloma virus negative tumor. Considering this fact, the human papilloma virus infection should be determined in all oropharyngeal cancers since it can have a major impact on the decision making process of the treatment.

We compared diagnostic accuracy of FDG PET and CT/MRI for regional lymph node metastasis of head and neck cancer according to the level of cervical lymph node. Thirty-two patients (M/F=27/5, 56±10yr) with head and neck cancer (glottic cancer; 16, tongue cancer; 9, others; 7) uncerwent FDG PET and CT/MRI (29/3) within 1 month before elective surgery with neck dissection (bilateral in 21, unilateral in 11). Whole body and additional regional neck images were acquired 1 hr after injection of FDG (555 MBq). PET images were visually interpreted according to the cervical lymph node level by 2 nuclear physicians independently without CT/MRI information. The findings of PET and CT/MRI were confirmed by the surgical pathology(153 levels of 43 neck dissections). There were 32 positive levels and 121 negative levels for metastatic lymph node lesions in pathology. The diagnostic sensitivity of PET [88%(28/32)] was significantly higher than that of CT/MRI [63%(20/32)] (p=0.021), whereas the specificity of PET [93%(113/121)] was similar to that of CT/MRI [92%(111/121)] (p>0.05). FDG PET was more sensitive than conventional CT/MRI in detecting metastatic lymph node of head and neck cancer

Purpose: Head and neck radiotherapy planning with positron emission tomography/computed tomography (PET/CT) requires the images to be reliably registered with treatment planning CT. Acquiring PET/CT in treatment position is problematic, and in practice for some patients it may be beneficial to use diagnostic PET/CT for radiotherapy planning. Therefore, the aim of this study was first to quantify the image registration accuracy of PET/CT to radiotherapy CT and, second, to assess whether PET/CT acquired in diagnostic position can be registered to planning CT. Methods and Materials: Positron emission tomography/CT acquired in diagnostic and treatment position for five patients with head and neck cancer was registered to radiotherapy planning CT using both rigid and nonrigid image registration. The root mean squared error for each method was calculated from a set of anatomic landmarks marked by four independent observers. Results: Nonrigid and rigid registration errors for treatment position PET/CT to planning CT were 2.77 ± 0.80 mm and 4.96 ± 2.38 mm, respectively, p = 0.001. Applying the nonrigid registration to diagnostic position PET/CT produced a more accurate match to the planning CT than rigid registration of treatment position PET/CT (3.20 ± 1.22 mm and 4.96 ± 2.38 mm, respectively, p = 0.012). Conclusions: Nonrigid registration provides a more accurate registration of head and neck PET/CT to treatment planning CT than rigid registration. In addition, nonrigid registration of PET/CT acquired with patients in a standardized, diagnostic position can provide images registered to planning CT with greater accuracy than a rigid registration of PET/CT images acquired in treatment position. This may allow greater flexibility in the timing of PET/CT for head and neck cancer patients due to undergo radiotherapy

Tumor Hypoxia is Independent of Hemoglobin and Prognostic for Loco-regional Tumor Control after Primary Radiotherapy in Advanced Head and Neck Cancer

Nordsmark, Marianne; Overgaard, Jens

2004-01-01

There is evidence that tumor hypoxia adversely affects loco-regional tumor control and survival in head and neck cancer. The aim of the current study was to compare pretreatment tumor oxygenation measured by Eppendorf pO2 electrodes with known prognostic factors in advanced head and neck tumors after definitive radiotherapy, and to evaluate the prognostic significance of these parameters on loco-regional tumor control. Sixty-seven patients, median age 56 years (22-82), all with primary stage III-IV squamous cell carcinoma were available for survival analysis. Tumor oxygenation was described as the fraction of pO2 values=2.5 mmHg (HP2.5) and the median tumor pO2. By regression analysis HP2.5 was independent of known prognostic factors including stage, pretreatment hemoglobin (Hb) and the largest tumor diameter at the site of pO2 measurement. By Kaplan-Meier analysis loco-regional tumor control at 5 years was in favor of less hypoxic tumors using either HP2.5 or median tumor pO2 as descriptors and stratifying by the median values. Also, Hb was prognostic of loco-regional tumor control at 5 years using the median value as cut off. HP2.5 as continuous parameter was highly significant for loco-regional tumor control in a multivariate analysis. In conclusion both HP2.5 and total Hb were prognostic for loco-regional tumor control, but HP2.5 as continuous variable was independently the strongest prognostic indicator for loco-regional tumor control after definitive primary radiotherapy in advanced head and neck tumors

The purpose of this study was to analyze the long-term success and factors potentially influencing the success of dental implants placed in patients with head and neck cancer who underwent radiation therapy with a minimum total dose of 50Gy during the years 1995-2010. Thirty-five patients (169 dental implants) were included in this study. Data on demographic characteristics, tumour type, radiation therapy, implant sites, implant dimensions, and hyperbaric oxygen therapy (HBOT) were obtained from the medical records and analyzed. Implant survival was estimated using Kaplan-Meier survival curves. Seventy-nine dental implants were placed in the maxilla and 90 in the mandible. The mean follow-up after implant installation was 7.4 years (range 0.3-14.7 years). The overall 5-year survival rate for all implants was 92.9%. Sex (Pradiation therapy delivery (P=0.005) had a statistically significant influence on implant survival. Age, time of implantation after irradiation, implant brand and dimensions, and HBOT had no statistically significant influence on implant survival. Osseointegrated dental implants can be used successfully in the oral rehabilitation of patients with head and neck cancer with a history of radiation therapy. Risk factors such as sex and the mode of radiation therapy delivery can affect implant survival. Copyright © 2018 International Association of Oral and Maxillofacial Surgeons.

The new modality of an integrated positron emission tomography/magnetic resonance imaging (PET/MRI) has recently been introduced but not validated. Our objective was to evaluate clinical performance of 18 F-fluoro-2-deoxyglucose ( 18 F-FDG) PET/MRI in patients with head and neck cancer. This retrospective study was conducted between January 2013 and February 2013. Ten patients (eight men, two women; mean age, 61.4±13.4 years) with histologically proven head and neck tumors were enrolled.Whole-body PET/MRI and regional positron emission tomography (PET) with dedicated MRI were sequentially obtained. Maximum standardized uptake value (SUVmax), SUVmean, metabolic tumor volume, total lesion glycolysis and contrast enhancement were analyzed. A total of ten whole-body positron emission tomography (PET), ten regional positron emission tomography (PET), ten dedicated MRI and ten regional PET/gadolinium-enhanced T1-weighted (Gd)-MRI images were analyzed for initial staging. Two nuclear medicine physicians analyzed positron emission tomography (PET) and PET/MRI with a consensus. One radiologist analyzed dedicated MRI. The primary lesions and number of metastatic lymph nodes analyzed from each image were compared. Eight patients were diagnosed with head and neck cancer (one tongue cancer, four tonsillar cancers, one nasopharyngeal cancer and two hypopharyngeal cancers) by histological diagnosis. Two benign tumors (pleomorphic adenoma and Warthin tumor) were diagnosed with surgical operation. Whole-body positron emission tomography (PET) and regional positron emission tomography (PET) attenuated by MRI showed good image quality for the lesion detection. Whole-body positron emission tomography (PET) and regional positron emission tomography (PET) detected ten primary sites and compensated for a missed lesion on dedicated MRI. A discordant number of suspicious lymph node metastases was noted according to the different images; 22, 16, 39 and 40 in the whole-body positron

Background and purpose: Although patients with early stage (T1/T2) laryngeal cancer (LC) are thought to have a low incidence of malnutrition, severe weight loss is observed in a subgroup of these patients during radiotherapy (RT). The objective of this study was to evaluate weight loss and nutrition-related symptoms in patients with T1/T2 LC during RT and to select predictive factors for early identification of malnourished patients. Methods: Of all patients with T1/T2 LC, who received primary RT between 1999 and 2007, the following characteristics were recorded: sex, age, TNM classification, tumour location, radiation schedule, performance status, quality of life, weight loss, and nutrition-related symptoms. The association between baseline characteristics and malnutrition (>5% weight loss during RT) was investigated by Cox regression analysis. Results: The study population consisted of 238 patients. During RT, 44% of patients developed malnutrition. Tumour location, TNM classification, RT on the neck nodes, RT dose, nausea/vomiting, pain, swallowing, senses problems, trouble with social eating, dry mouth and the use of painkillers were all significantly associated with malnutrition. In the multivariate analysis, RTs on both the neck nodes (HR 4.16, 95% CI 2.62-6.60) and dry mouth (HR 1.72, 95% CI 1.14-2.60) remained predictive. Nevertheless, RT on the neck nodes alone resulted in the best predictive model for malnutrition scores. Conclusions: Patients with early stage laryngeal cancer are at risk of malnutrition during radiotherapy. Radiotherapy on the neck nodes is the best predictor of malnutrition during radiotherapy. Therefore, we suggest to offer nutritional counselling to all the patients who receive nodal irradiation.

Information about recurrence and prognostic factors is important for patients and practitioners to set realistic expectations about the chances of full recovery and to reduce patient anxiety and uncertainty. Therefore, the purpose of this study was to assess recurrence and prognostic factors for neck pain in a chiropractic patient population at 1 year from the start of the current episode. Within a prospective cohort study, 642 neck pain patients were recruited by chiropractors in Switzerland. After a course of chiropractic therapy, patients were followed up for 1 year regarding recurrence of neck pain. A logistic regression analysis was used to assess prognostic factors for recurrent neck pain. The independent variables age, pain medication usage, sex, work status, duration of complaint, previous episodes of neck pain and trauma onset, numerical rating scale, and Bournemouth questionnaire for neck pain were analyzed. Prognostic factors that have been identified in previous studies to influence recovery of neck pain are psychologic distress, poor general health at baseline, and a previous history of pain elsewhere. Five hundred forty five patients (341 females), with a mean age of 42.1 years (SD, 13.1) completed the 1-year follow-up period. Fifty-four participants (11%) were identified as "recurrent." Prognostic factors associated with recurrent neck pain were previous episodes of neck pain and increasing age. The results of this study suggest that recurrence of neck pain within 1 year after chiropractic intervention in Swiss chiropractic patients presenting from varied onsets is low. This study found preliminary findings that older age and a previous episode of neck may be useful predictors of neck pain recurrence within 1 year.

We retrospectively examined the effect of Cepharanthin to prevent radiation xerostomia in 37 cases of head and neck cancer. In the Cepharanthin group, the degree of xerostomia was milder than in the non-Cepharanthin group in spite of higher normal tissue complication probability (NTCP) and mean dose (MD) of parotid glands. In the non-Cepharanthin group, the degree of xerostomia was significantly correlated with NTCP and MD of parotid glands. MD of parotid glands and use of Cepharanthin were significantly related to more severe xerostomia by multivariate analysis with logistic regression. Cepharanthin may prevent radiation xerostomia after radiotherapy for head and neck cancer. (author)

Enhanced CAR T cell therapy: A novel approach for head and neck cancers.

Head and neck cancer that presents in locally advanced stages often results in a bad prognosis with an increased recurrence rate even after curative resections. Radiation therapy is then applied, with multiple side effects, as adjuvant regional therapy. Because of the high rate of recurrence and mortality, new therapies are needed for patients suffering from head and neck malignant tumors.CAR (chimeric antigen receptor) T cell therapy, which was first devised about 25 years ago, causes the killing or apoptosis of target tumor cells through inducing the secretion of cytokines and granzymes by T cells (Cheadle et al., 2014). CARs are comprised of three canonical domains for antigen recognition, T cell activation, and co-stimulation, and are synthetic receptors that reprogram immune cells for therapeutic treatment of multiple tumors (Sadelain, 2017).

Taste disorders caused by radiation therapy for head and neck cancer are common. This prospective study of 40 patients with head and neck cancer assessed changes in taste sensations during radiation therapy. The relationship between the time course and the degree of taste disorder was studied. The taste recognition threshold and supra-threshold taste intensity performance for the four basic tastes were measured using the whole-mouth taste method before, during, and after radiation therapy. Bitter taste was affected most. An increase in threshold for sweet taste depended upon whether the tip of tongue was included within the radiation field. The slope of the taste intensity performance did not change during or after radiotherapy. The pattern of salivary dysfunction was different from that of taste dysfunction. The main cause of taste disorders during radiation support the hypothesis that taste dysfunction is due to damage to the taste buds in the radiation field. (author)
