    Curie-therapy conventionally comes before surgery in the treatment of cervical cancer, either alone or after a concomitant chemotherapy. The authors report a study of the impact of a reverse sequence (surgery before curie-therapy) on the exeresis quality and on the evolution of operable tumours. Among women treated between 2004 and 2009, 40 have been identified who had surgery before curie-therapy. Ages, tumour stages, average doses, and treatment procedures are discussed. The notably high rate of vaginal sections could be reduced or avoided by using the conventional protocol (curie-therapy before surgery). Short communication

    Conservative treatment has become a valid alternative to radical surgery in most cases of cancer of the anal canal and in selected cases of cancer of the low rectum. In this strategy interstitial curietherapy has an appreciable role to play. The results of a series of 369 patients followed more than 3 years indicate that implantation of Iridium-192 is effective not as sole treatment but as a booster dose 2 months after a course of external beam or intracavitary irradiation. The dose delivered did not exceed 20 to 30 Gy and the implantations were always performed in one plane using either a plastic template or a steel fork. Three groups of cases must be considered: (a) among 221 patients with epidermoid carcinoma of the anal canal, the rate of death related to treatment failures was 20% and among the patients cured more than 90% retained normal sphincter function. (b) In 90 patients with T1-T2 invasive adenocarcinoma of the rectum, Iridium-192 was carried out after four applications of contact X ray therapy. The rate of control was 84%. (c) In 62 elderly, poor risk patients with T2-T3 tumor of the low rectum initially suitable for an abdomino-perineal resection, a tentative extension of the field of conservation was made using a split-course protocol combining a short course of external beam irradiation at a dose of 30-35 Gy in 10 fractions over 12 days and an Iridium-192 implant. The rate of death due to treatment failures was 14.5% and among the patients controlled 97% had a normal anal function. These results show that implantations of Iridium-192 may contribute to the control of anal and rectal cancers and may spare many patients a permanent colostomy, but the treatment requires great care in patient selection, treatment protocol, technical details, and follow-up. This treatment policy must be conceived as a team work of radiation oncologists and surgeons.

    The authors report the assessment of the feasibility of a dose escalation when using MRI-guided pulsed rate intracavitary curietherapy with manual optimization of dwell times on 25 patients treated for an invasive cervical carcinoma. A first group of patients comprised 5 women with a stage Ib2 cancer who had only one curietherapy before surgical intervention. The second group comprises eleven women presenting limited stage Ib2 or IIa or IIb cancers who have been treated by a concomitant association of radiotherapy and chemotherapy followed by MRI-guided pulsed rate intracavitary curietherapy and later by surgical intervention. The third group comprised nine women presenting a locally advanced cancer who have been treated by chemotherapy followed by a MRI-guided pulsed rate intracavitary curietherapy. It appears that MRI-guided pulsed rate intracavitary curietherapy could be an efficient mean to increase the dose in the pelvic central part. Short communication

    Deep neck space abscesses are common otolaryngological emergencies, and prompt incision and drainage is the treatment of choice. Head and neck cancers often present with cervical metastases that may become secondarily infected. Clinical presentation is similar to a deep neck abscess. Surgical drainage of such collections has implications on subsequent treatment. In this case series, we describe six cases with this unusual presentation that were subsequently found to have a head and neck malignancy, and where three patients had their abscesses treated surgically. We aim to raise awareness of this unusual presentation of a head and neck carcinoma, and to avoid a potential pitfall in the management of deep neck abscess.

    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.

    Lymphatic metastasis is the most commonly seen route for the spread of malignant epithelial tumors. Oral cancers derived from epithelial tissue occur more often in the head and neck regions with a high lymphatic metastasis rate. According to reports from Chinese researchers, the lymphatic metastasis rate of oral cancer could be as high as 40%, and clearing those involved lymph nodes in neck is one of the most important methods to treat the disease.

    Over the past two decades, brachytherapy has played an ever expanding role in the definitive radiotherapy of prostate cancer. Brachytherapy surpasses external beam radiotherapy in its ability to deliver intense intra-prostatic dose escalation. Although initially low dose rate permanent seed brachytherapy was favored for favorable risk prostate cancers, and high dose rate temporary brachytherapy for intermediate and advanced disease, both types of brachytherapy now have a place across all the risk groups of localized prostate cancer. This article will review indications and patient selection, planning and technical aspects, toxicity and efficacy for both low and high dose rate prostate brachytherapy. (author)

    2017-02-01

    Objective Complementary and alternative medicine, or integrative medicine, has become increasingly popular among patients with head and neck cancer. Despite its increasing prevalence, many patients feel uncomfortable discussing such therapies with their physicians, and many physicians are unaware and underequipped to evaluate or discuss their use with patients. The aim of this article is to use recent data to outline the decision making inherent to integrative medicine utilization among patients with head and neck cancer, to discuss the ethical implications inherent to balancing integrative and conventional approaches to treatment, and to highlight available resources to enhance head and neck cancer providers' understanding of integrative medicine. Data Sources Randomized controlled trials involving integrative medicine or complementary and alternative medicine treatment for cancer patients. Review Methods Trials were drawn from a systematic PubMed database search categorized into cancer prevention, treatment, and symptom management. Conclusions Integrative medicine is gaining popularity for the management of cancer and is most commonly used for symptom management. A number of randomized controlled trials provide data to support integrative therapies, yet physicians who treat head and neck cancer may be faced with ethical dilemmas and practical barriers surrounding incorporation of integrative medicine. Implications for Practice In the management of head and neck cancer, there is an increasing demand for awareness of, dialogue about, and research evaluating integrative medicine therapies. It is important for otolaryngologists to become aware of integrative therapy options, their risks and benefits, and resources for further information to effectively counsel their patients.

    Brachytherapy plays an important role in the treatment of patients with cervical carcinoma. Technical modalities have evolved during the last years and have benefited from imaging modalities development, specially MRI. Imaging modalities contribute to a better knowledge of tumoral extension and critical organs. Ultrasound during brachytherapy has led to the almost complete eradication of uterine perforation. In the future, a more systematic use of systems allowing optimization may induce a better dose distribution in the tumor as well as in the critical organs. Recent data provided information in favor of a better analysis in the relative role of dose-rate, total dose and treated volume and their influence on the local control and complication incidence. Concomitant radio-chemotherapy represents a standard in the treatment of patients with tumoral size exceeding 4 cm. Some questions still remain: is concomitant chemotherapy of benefit during brachytherapy? Is there any place for complementary surgery, specially in patients with complete response after external irradiation with concomitant chemotherapy and brachytherapy? In order to answer the former question, a phase III randomized trial is going to start, with the Federation Nationale des Centres de Lutte Contre le Cancer as a promoter. (authors)

    Purpose. - This study aimed at analyzing the evolution and type of recurrence in patients treated for stage I endometrial carcinomas, in order to define the respective roles of adjuvant radiotherapy and brachytherapy. Patients and methods. - This mono-centric retrospective study was conducted at Centre Alexis-Vautrin, Nancy, France, between January 1995 and December 2000 on all the patients surgically treated for an endometrial cancer, and then treated with high dose rate vaginal brachytherapy. The brachytherapy was delivered in two or three fractions of 7 Gy at 5 mm from the applicator. Results. - In the good prognosis group, the specific and overall survivals at 5 years were respectively 96.5 and 94.2% with no local recurrence demonstrated. In the intermediate prognostic group, the specific and overall survivals at 5 years were respectively 88 and 85%, with six locoregional recurrences observed among those who did not undergo lymphadenectomy; the overall survival at 5 years was significantly decreased in the absence of external radiation. In the group of poor prognosis (stages II and III), the specific survival at 5 years was respectively 72.8 and 67 %, and the overall survival at 5 years 66.7 and 56.4%. Conclusion. - Results for local control and survival as well as for tolerance were good. So we have decided to deliver high rate brachytherapy for all intermediate or poor prognosis patients and we have abandoned pelvic radiotherapy for good prognosis tumours (stages IA: no myometrium invasion with grade 3 and >50% of myometrium invasion with grades 1 and 2), whatever the lymph nodes surgery they had. We now propose pelvic radiotherapy only for intermediate prognosis tumours (such as IA > 50% of myometrium invasion with grade 3 and IB stages), if patients did not have any lymphatic surgery, or for bad prognosis tumours.

    Full Text Available Cancerous patients, under the chemotherapy or radiotherapy, are at high risk of malnutrition due to the associated complications with the treatment procedures such as chewing problems, dysphagia, nausea etc. Considering the patients’ history of alcohol consumption, smoking or any other diseases and performing several physical examinations are essential in early identification of high-risk patients for nutritional complications, losing unintentional weight and fat free mass. In this review, we tried to briefly explain the risk of malnutrition in patients with head and neck cancers who are undergoing surgery, chemotherapy and radiotherapy. Oral nutrition, nasogastric tube and percutaneous endoscopic gastrostomy  are different methods of nutritional interventions, which have been compared due to their efficacy in maintaining the patients’ weight. In this study, we reviewed the results obtained in clinical trials about the efficacy of intense nutritional intervention on limiting the chemoradiotherapy-associated complications in patients with head and neck cancers.

    We aim to review the technique and clinical applications of perfusion CT (PCT) of head and neck cancer. The clinical value of PCT in the head and neck includes detection of head and neck squamous cell carcinoma (HNSCC) as it allows differentiation of HNSCC from normal muscles, demarcation of tumor boundaries and tumor local extension, evaluation of metastatic cervical lymph nodes as well as determination of the viable tumor portions as target for imaging-guided biopsy. PCT has been used for prediction of treatment outcome, differentiation between post-therapeutic changes and tumor recurrence as well as monitoring patient after radiotherapy and/or chemotherapy. PCT has a role in cervical lymphoma as it may help in detection of response to chemotherapy and early diagnosis of relapsing tumors.

    Although the functional merits of preserving cervical nerves in neck dissection for head and neck cancer have been reported, the oncologic safety has not yet been determined. Therefore, the purpose of this study was to evaluate the safety of cervical nerve preservation. A retrospective chart review was performed on patients with head and neck cancer who had been treated by neck dissection between 2009 and 2014 at Kyoto Medical Center. Management of cervical nerves and clinical results were analyzed. A total of 335 sides of neck dissection had been performed in 222 patients. Cervical nerves were preserved in 175 neck sides and resected in 160 sides. The 5-year overall survival (OS) rate calculated by the Kaplan-Meier method was 71%. The 5-year neck control rate was 95% in cervical nerve preserved sides and 89% in cervical nerve resected sides. Preserving cervical nerves in neck dissection is oncologically safe in selected cases. © 2017 Wiley Periodicals, Inc.

    The management of patients with recurrent head and neck cancers is complex. Concerns over toxicity with re-irradiation have limited its use in the clinical setting. Stereotactic Body Radiation Therapy (SBRT) has emerged as a highly conformal and precise type of radiotherapy and has the advantage of sparing normal tissue. Although SBRT is an attractive treatment modality, its use in the clinic is limited, given the technically challenging nature of the procedure. In this review, we attempt to provide a comprehensive overview of the role of re-irradiation in patients with recurrent head and neck cancers, with particular attention to the advent of SBRT and its use with systemic therapies such as cetuximab.

    A critical review of the head and neck cancer research highlights of the American Society of Clinical Oncology (ASCO) meeting 2016, held in June 2016 in Chicago, is presented in this podcast. Considering the most interesting and practice-changing trials reported at the meeting, the key trial comparing gemcitabine plus cisplatin against 5-FU (5-fluorouracil) plus cisplatin in the treatment of nasopharyngeal carcinoma is highlighted. The GORTEC2007-02 trial comparing induction docetaxel/platinum/5-FU followed by cetuximab-radiotherapy against concurrent chemo-radiotherapy for N2b/c-N3 non operated stage III-IV squamous cell cancer of the head and neck is also discussed. An overview of the research reported using immunotherapy in head and neck cancer is also given, considering maturing data and particularly in relapsing patients, where response rates, though low, are better than with current therapies, and the responses are long lasting. Future developments are also considered, again with a focus on immunotherapy, but also considering combination with radiotherapy and chemoradiation.

    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.

    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.

    Full Text Available Head and neck cancer (HNC is the sixth most common malignancy world-wide, however the survival rate has not improved for the past 20 years. In recent years, the cancer stem cell (CSC hypothesis has gained ground in several malignancies and there is mounting evidence suggesting CSCs mediate tumor resistance to chemotherapy and radiation therapy. However, the CSC theory is also challenged at least in certain types of cancer. Here we review the progress of CSC studies in HNC, which suggest that HNC conforms to the CSC model. The identified CSC markers and their tumor initiation properties provide a framework for the development of novel therapeutic strategies for HNC.

    Patients with head and neck cancer are seeking improved surgical procedures to avoid severe defects that result from head and neck cancer resection. Free flap reconstruction provides vascularized tissue that has been transferred from a distant donor site on a patient's body to a recipient site, markedly improving wound closure and protecting structures of the head and neck. This article discusses free flap procedures for reconstruction after head and neck cancer resection, including the following procedure phases: airway protection and neck dissections, tumor resection, flap harvest, microvascular anastomosis of the flap, and reconstruction and closure. The article also explains specific risk factors for patients undergoing free flap procedures that have been identified in the literature and include procedure length, hypothermia, and pressure injuries. Each of these factors is discussed regarding its specific effect on this patient population, and the nursing interventions to reduce these risks are identified.

    Head and neck cancer typically refers to epithelial malignancies of the upper aerodigestive tract and may include neoplasms of the thyroid, salivary glands, and soft tissue, bone sarcomas, and skin cancers. Two-thirds of patients present with advanced disease involving regional lymph nodes at the time of diagnosis. A thorough history and detailed examination are integral to oncologic staging and treatment planning. This article begins with an overview of the head and neck examination (with special attention to detailed findings with clinical implications), followed by a discussion of the major head and neck subsites, and clinical pearls surrounding the examination.

    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. PMID:20628529

    Head and neck cancers (HNCs) are a highly heterogeneous group of tumours that are associated with diverse clinical outcomes. Recent evidence has demonstrated that human papillomavirus (HPV) is involved in up to 25% of HNCs; particularly in the oropharyngeal carcinoma (OPC) subtype where it can account for up to 60% of such cases. HPVs are double-stranded DNA viruses that infect epithelial cells; numerous HPV subtypes, including 16, 18, 31, 33, and 35, drive epithelial cell transformation and tumourigenesis. HPV positive (HPV+) HNC represents a distinct molecular and clinical entity from HPV negative (HPV-) disease; the biological basis for which remains to be fully elucidated. HPV positivity is strongly correlated with a significantly superior outcome; indicating that such tumours should have a distinct management approach. This review focuses on the recent scientific and clinical investigation of HPV+ HNC. In particular, we discuss the importance of molecular and clinical evidence for defining the role of HPV in HNC, and the clinical impact of HPV status as a biomarker for HNC.

    The aim of the present study was to retrospectively evaluate the incidence of hypothyroidism in locally advanced head and neck cancer patients who received radiotherapy (RT) either with or without neck dissection. From January 2000 to December 2005, 115 patients with locally advanced head and neck cancer and who received definitive RT or postoperative RT including standard anterior low-neck field were recruited to be part of this study. Nineteen patients had undergone ipsilateral neck dissection, whereas, 18 patients underwent bilateral neck dissection, and 78 patients were received RT alone. Patients' ages ranged from 28 to 85 years (median, 59 years) and there were a total of 73 male and 42 female patients. The primary tumor sites were the oral cavity, oropharynx, hypopharynx, larynx, and other sites in 18, 40, 28, 22 and 7 patients, respectively. Radiation dose to the thyroid gland ranged from 44 Gy to 66 Gy with a median dose of 50 Gy. Follow-up time ranged from 2 to 91 months, with a median of 29 months. The 1- and 3- year incidence of hypothyroidism was 28.7% (33 patients) and 33.0% (38 patients), respectively. The median time to detection of hypothyroidism was 8.5 months (range, 0 to 36 months). A univariate analysis revealed that neck node dissection was a risk factor for hypothyroidism (p=0.037). However, no factor was statistically significant from the results of a multivariate analysis. Patients treated for advanced head and neck cancer with radiotherapy with or without neck dissection will develop hypothyroidism. It is important to check the thyroid function periodically in these patients especially with the risk factor of neck node dissection.

    Since 1993, ten multidisciplinary symposia were organized at The Netherlands Cancer Institute on the diagnosis and treatment of malignancies of the head and neck. The symposia are meant to provide up-to-date teaching for physicians by world-renowned speakers. The previous symposia dealt with sarcomas, reconstruction, cancer in young patients, salivary glands, melanoma, unknown primaries, as well as several other topics. This 10th symposium focused on skin cancer of the head and neck. There are many types of skin cancer and the differential diagnosis can often be difficult. In this symposium, diagnosis, molecular biology, epidemiology, staging and the treatment of various skin cancers were discussed by leaders in the field. There were over 200 participants from many different countries in Europe and overseas, representing specialties in the fields of dermatology, maxillofacial surgery, otolaryngology, head and neck surgery, general surgery, plastic and reconstructive surgery, and radiotherapy.

    Surgery and combinations of traditional treatments are not successful enough particularly for advanced stage head and neck cancer. The major disadvantages of chemotherapy and radiation therapy are the lack of specificity for the target tissue and toxicity to the patient. As a result, gene therapy may offer a more specific approach. The aim of gene therapy is to present therapeutic genes into cancer cells which selectively eliminate malignant cells with no systemic toxicity to the patient. This article reviews the genetic basis of head and neck cancers and important concepts in cancer gene therapy: (i) inhibition of oncogenes; (ii) tumor suppressor gene replacement; (iii) regulation of immune response against malignant cells; (iv) genetic prodrug activation; and (v) antiangiogenic gene therapy. Currently, gene therapy is not sufficient to replace the traditional treatments of head and neck cancers, however there is no doubt that it will have an important role in the near future.

    Full Text Available Abstract Background Reconstruction of the head and neck after adequate resection of primary tumor and neck dissection is a challenge. It should be performed at one sitting in advanced tumors. Defects caused by the resection should be closed with flaps which match in color, texture and hair bearing characteristics with the face. Cervicopectoral flap is a one such flap from chest and neck skin mainly used to cover the cheek defects. Methods This study included twelve patients presenting with cancer of the head and neck to Izmir Ataturk Training Hospital and Adnan Menderes University Hospital. Tumor resection and neck dissection was performed in one session by the same surgeon. A single incision was made and a medially based cervicopectoral fascio-cutaneous flap was used for surgical exposure in neck dissection and for closure of defects after tumor resection. Results There was no major complication. Two flaps had partial superficial epidermolysis at the suture line. Good aesthetic and functional results were achieved. Conclusion The cervicopectoral flap is an excellent alternative for the reconstruction of head and neck. Harvesting and application of the flap is rapid and safe. Only a single incision is sufficient for dissection and flap elevation. This flap achieves perfect surgical exposure, makes neck dissection easy and allows one to perform both tumor resection and neck dissection in one session.

    The idea, and subsequent construction, of a dose rate meter for measuring linear exposure dose originated in those pilot centres of Curietherapie which wished to replace radium by the artificial radionucleides, Irdium-192, Caesium-137 etc. The aparatus makes it possible to measure, directly and quickly, the activity of a specified length of a linear source, a measurement which has only been possible until now by dividing the exposure dose by the length whose activity it is desired to know. If the dose-rate obtained by these two methods agrees, this apparatus shortens the time for which the sources need to be handled, thereby reducing the danger of irradiation to staff and technicians. The apparatus is thus able to reveal heterogeneity of activity along the length of a line-source. In the specific case of Iridium, our experience shows that wires which have been used in several applications may develop mechanical bends and constrictions, which can lead to fluctuation in dose rate along their length. The apparatus was first constructed in 1967, after preliminary experiments in 1965. As Curietherapy has become more widely used, the apparatus has undergone many modifications which is more precise and specific than it was initially. At the present time it can only be used with Iridium as wire, and with Caesium in the form of trains of seeds (corresponding to the AGS sources) or needles. Nevertheless, a third scale is under consideration, for use with newer radioelements, which may be used in future.

    OBJECTIVE To determine predictors of pain 1 year after the diagnosis of head and neck cancer. DESIGN Prospective, multisite cohort study. SETTING Three academically affiliated medical centers. PATIENTS The study population comprised 374 previously untreated patients with carcinoma of the upper aerodigestive tract. MAIN OUTCOME MEASURES Participants were surveyed before treatment and 1 year thereafter. Multivariate analyses were conducted to determine predictors of the 36-Item Short-Form Instrument (SF-36) bodily pain score 1 year after diagnosis. RESULTS The mean SF-36 bodily pain score at 1 year was 65, compared with 61 at the time of diagnosis (P = .004), and 75, the population norm (lower scores indicate worse pain). Variables independently associated with pain included pretreatment pain score (P neck dissection (P = .001), feeding tube (P = .05), xerostomia (P pain medication (P neck cancer pain and current smoking and problem drinking did not reach significance (P = .07 and P = .08, respectively). CONCLUSIONS Aggressive pain management may be indicated for patients with head and neck cancer 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 use, and alcohol abuse may also reduce pain and improve quality of life among patients with head and neck cancer.

    Based on a cohort of 150 patients treated by curie-therapy for a prostate cancer, the authors report the analysis of the influence of some technical modifications (use of an automatic stepper at the beginning of a second period, and of a high frequency echographic probe during a third period) on the urinary toxicity. This toxicity has been assessed by using the urinary retention rate, and the difference between the maximum and initial International Prostate Symptom Score (IPPS). Rectal morbidity has been scaled according to a modified Radiation Therapy Oncology Group (RTOG) scale. It appears that the occurrence of urinary retention after prostate radiotherapy decreases with practice and use of the automatic stepper. It seems that there is no impact on urinary morbidity (urinary retention excluded) nor on rectal morbidity. Short communication

    Purpose: The aim of this retrospective analysis was to analyze the results of radiotherapy administered to patients with neck node metastases from an unknown primary cancer, with or without neck dissection. Materials and Methods: From January 1986 to December 2005, 88 patients with neck node metastases from an unknown primary cancer were treated with curative intent. The age of the patients ranged from 35 to 74 years (median age, 59 years). There were 74 male and 14 female patients. Distribution of patients by N status was as follows: N1, 4 patients; N2a, 10 patients; N2b, 48 patients; N2c, 8 patients; N3, 18 patients. Fifty-one patients underwent neck dissection and 37 patients had only a biopsy (31 patients had fine-needle aspiration and 6 patients had an excisional biopsy). All patients received radiotherapy. The follow-up time ranged from 1 to 154 months, with a median time of 32 months. Results: The overall survival (OS) and disease-free survival (DFS) rate at 5 years were 43.9% and 41.7%, respectively. The factors associated with the OS rate were neck dissection, and a subsequent primary tumor. Factors associated with the DFS rate were N stage, neck dissection, and a subsequent primary tumor. Neck failure was noted in 15 patients, distant metastases in 18 patients, and a subsequent primary tumor in 8 patients. Conclusion: With comprehensive radiotherapy given to the bilateral neck and the potential mucosal sites, good survival rates can be obtained in patients with neck node metastases from an unknown primary cancer. However, considering the side effects, a randomized trial is required to determine the optimal radiotherapy volume.

    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.

    2013-12-13

    Head and neck surgery is one of the basic principles of head and neck cancer therapy. Surgical errors and malpractice can have fatal consequences for the treated patients. It can lead to functional impairment and has impact in future chances for disease related survival. There are many risks for head and neck surgeons that can cause errors and malpractice. To avoid surgical mistakes, thorough preoperative management of patients is mandatory. As there are ensuring operability, cautious evaluation of preoperative diagnostics and operative planning. Moreover knowledge of anatomical structures of the head and neck, of the medical studies and data as well as qualification in modern surgical techniques and the surgeons ability for critical self assessment are basic and important prerequisites for head and neck surgeons in order to make out risks and to prevent from mistakes. Additionally it is important to have profound knowledge in nutrition management of cancer patients, wound healing and to realize and to be able to deal with complications, when they occur. Despite all precaution and surgical care, errors and mistakes cannot always be avoided. For that it is important to be able to deal with mistakes and to establish an appropriate and clear communication and management for such events. The manuscript comments on recognition and prevention of risks and mistakes in the preoperative, operative and postoperative phase of head and neck cancer surgery.

    Full Text Available Purpose: To identify the occurrence of clinical and subclinical hypothyroidism among head and neck cancer patients receiving radiation to the neck and to justify routine performing of thyroid function tests during follow-up. Materials and Methods: This is a prospective nonrandomized study of 45 patients of head and neck cancer, receiving radiotherapy (RT. Thyroid stimulating hormone and T4 estimations were done at baseline and at 4 months and 9 months following RT. Results: Of the 45 patients, 37(82.2 % were males and eight (17.8 % were females. All patients received radiation to the neck to a dose of >40Gy. 35.6% received concurrent chemotherapy. Two patients underwent prior neck dissection. Fourteen patients (31.1% were found to have clinical hypothyroidism (P value of 0.01. Five (11.1% patients were found to have subclinical hypothyroidism with a total 19 of 45 (42.2% patients developing radiation-induced hypothyroidism. Nine of 14 patients with clinical hypothyroidism were in the age group of 51 to 60 years (P=0.0522. Five of 16 patients who received chemoradiation and nine of 29 who received RT alone developed clinical hypothyroidism. Above 40 Gy radiation dose was not a relevant risk factor for hypothyroidism. Conclusion: Hypothyroidism (clinical or subclinical is an under-recognized morbidity of external radiation to the neck which is seen following a minimum dose of 40 Gy to neck. Recognizing hypothyroidism (clinical or subclinical early and treating it prevents associated complications. Hence, thyroid function tests should be made routine during follow-up.

    Treatments for head and neck cancers are generally complex and debilitating. Surgery, often mutilating, profoundly affects the relationship between oneself and others and causes verbal communication, breathing and swallowing difficulties. The functional and aesthetic sequelae are a constant reminder to the patient of the disease and make them conscious of their appearance. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Full Text Available In this century, cancer incidence has become one of the most significant problems concerning human. Conventional radiotherapy damage healthy tissue and in some cases may cause new primary cancers. This problem can be partially solved by hadron therapy which would be more effective and less harmful compared to other forms of radiotherapies used to treat some cancers. Although carbon ion and proton therapy both are effective treatments, they have serious differences which are mentioned in this paper and compared between the two methods. Furthermore, various treatments have been performed on head and neck cancer with hadrons so far will be discussed.

    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.

    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.

    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.

    Approximately 15,000 cases of early stage prostate cancer T1 and T2 are diagnosed every year in France by testing for PSA and performing prostatic biopsies. The treatment of these localized forms is based in most cases on radical prostatectomy or nn external beam radiotherapy. Although the ontological results obtained by these two therapeutic methods are satisfactory and equivalent in the long term, the side effects can be important. For a number of years, trans-perineal brachytherapy using permanent implants of iodine -125 or palladium-103 has proved itself as an alternative therapy with equivalent medium to long-term results. The low urinary, digestive and sexual side effects of prostate brachytherapy are important reasons for the enthusiasm among patients and the medical community for this therapy and the growing number of applications and centres which practice it. In September 1998 we started the prostate brachytherapy programmes- in Marseilles with close collaboration between the department of urology of the Hopital Salvator, and the departments of radiotherapy, medical imaging and medical physics of the Institut Paoli-Calmettes. To date, around 250 patients with localized adenocarcinoma of the prostate have benefited from this alternative therapy in our centre. Preliminary results, with a 3 year-follow-up, are comparable to results published in the literature by pioneer teams. (authors)

    Concurrent chemoradiotherapy were performed for 18 patients with unresectable head and neck squamous cell cancer. Chemotherapy, consisting of CDDP (40 mg/m{sup 2}, Day 1 and 8) and 5-FU (200 mg/m{sup 2}, 24-h continuous infusion through Day 1-5 and 8-12), with concurrent radiotherapy (2 Gy/day, 5 days/w) were administered and repeated 2-3 courses in every 5 weeks. Mucositis and myelo-suppression were the main side effects observed, but all of them were tolerable. Total response rate and complete response rate was 94.4% and 55.6%, respectively. Out of six patients requiring tracheotomy for airway obstruction due to bulky tumor, four achieved sufficient tumor shrinkage by the treatment and could obtain closure of the stoma. Two patients whose neck lymph nodes were still remaining after chemoradiotherapy, could obtain local control by supplemental neck dissection surgery. These regimen is feasible and effective for locally advanced head and neck cancer. (author)

    2008-09-01

    The aim of treating head and neck cancer is to eliminate the tumor and save functions as much as possible. Despite all efforts the vital (swallowing) and communicative (phonation, articulation) functions can be injured. The treatment of dysphagia is the most important in the rehabilitation, because it can lead to fatal complications: aspiration pneumonia (for example aspiration of saliva), dehydration, malnutrition. According to the localization of the lesion we distinguish oropharyngeal and esophageal dysphagia. The aspiration may be pre-, intra- and post-deglutition. The aspiration without coughing is called silent aspiration which is mainly seen in neurogenic dysphagia, but can also happen in head and neck cancer patients. There are different possibilities to compensate the failing functions in the phoniatric rehabilitation. The swallowing therapy includes causal, compensatory and dietary strategies. In addition to the swallowing therapy the treatment of communicative dysfunctions with articulation exercises will also improve the quality of life of the patients.

    In patients with locally unresectable head and neck cancer with large nodal involvement, the expected five-year survival is as low as 1-2%. To improve the prognosis of these patients, we studied the usefulness of concurrent chemoradiotherapy in a phase 11 trial. Between September 1996 and May 1999, thirty-five patients with locally unresectable head and neck cancer were administered concurrent chemoradiotherapy consisting of low-dose and long-term treatment with cisplatin (CDDP) plus 5-fluorouracil (5FU), or (L-CF); the L-CF regimen consisted of CDDP, 3 mg/m{sup 2} on 5 days of the week and 5FU, 150 mg/m{sup 2} as a 24-hour infunsion on 5 days of the week. Concurrently, conventional radiotherapy was given up to total dose of around 60 Gy. In the 33 patients evaluable for response, 17 complete and 9 partial responses were noted, with an overall response rate of 79%. Oral mucositis and myelosuppression were the major side effects and mucositis was a dose limiting toxicity. This study demonstrates increase in survival among the responders (complete+partial) in the concurrent chemoradiotherapy setting. However 8 local relapses were eventually noted in the 17 complete responders. We concluded that this treatment strategy was beneficial in patients with locally unresectable head and neck cancer.

    Abstract Background: Multimodality therapy constitutes the standard treatment of advanced and recurrent head and neck cancer. Since locoregional recurrence comprises a major obstacle in attaining cure, the role of intraoperative radiation therapy (IORT) as an add-on in improving survival and local control of the disease has been investigated. IORT allows delivery of a single tumoricidal dose of radiation to areas of potential residual microscopic disease while minimizing doses to normal tissues. Advantages of IORT include the conformal delivery of a large dose of radiation in an exposed and precisely defined tumor bed, minimizing the risk of a geographic miss creating the potential for subsequent dose reduction of external beam radiation therapy (EBRT). This strategy allows for shortening overall treatment time and dose escalation. The aim of this review is to summarize recent published work on the use of IORT as an adjuvant modality to treat common head and neck cancer in the primary or recurrent setting. Methods: We searched the Medline, Scopus, Ovid, Cochrane, Embase, and ISI Web of Science databases for articles published from 1980 up to March 2016. Results: Based on relevant publications it appears that including IORT in the multimodal treatment may contribute to improved local control. However, the benefit in overall survival is not so clear. Conclusion: IORT seems to be a safe, promising adjunct in the management of head and neck cancer and yet further well organized clinical trials are required to determine its role more precisely.

    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)

    Background 18F-fluoro-2-deoxy-D-glucose (18F-FDG) accumulations are commonly seen in the neck-related muscles of the surgical and non-surgical sides after surgery with neck dissection (ND) for oral cancers, which leads to radiologists having difficulty in diagnosing the lesions. To examine the alterations in 18F-FDG accumulation in neck-related muscles of patients after ND for oral cancer. Material and Methods 18F-FDG accumulations on positron emission tomography (PET)-computed tomography (CT) in neck-related muscles were retrospectively analyzed after surgical dissection of cervical lymph nodes in oral cancers. Results According to the extent of ND of cervical lymph nodes, the rate of patients with 18F-FDG-PET-positive areas increased in the trapezius, sternocleidomastoid, and posterior neck muscles of the surgical and/or non-surgical sides. In addition, SUVmax of 18F-FDG-PET-positive areas in the trapezius and sternocleidomastoid muscles were increased according to the extent of the ND. Conclusions In evaluating 18F-FDG accumulations after ND for oral cancers, we should pay attention to the 18F-FDG distributions in neck-related muscles including the non-surgical side as false-positive findings.

    2011-08-01

    Salvage surgery is the mainstay of treatment for recurrences or secondary primary tumors in areas that were irradiated earlier. However, locoregional recurrence remains the main cause of death after surgery. Adjuvant reirradiation dramatically reduces locoregional recurrences but the risk-benefit ratio seems to be advantageous mostly for residual microscopic disease. In contrast, the rate of distant metastasis among reirradiated patients indicates that the local treatment alone is not sufficient. Full-dose exclusive chemo-reirradiation (over 60 Gy) can cure a subset of patients when surgery is not feasible. However, reirradiation is associated with a significant rate of severe toxicity and should, therefore, be compared with chemotherapy in randomized trials. Accrual may be difficult because of selection biases such as tumor volume, small volumes (largest axis less than 3-4 cm) being more likely to be irradiated. In addition, patients in poor general condition with severe comorbidities, organ dysfunction, or incomplete healing after salvage surgery, are unlikely to benefit from reirradiation. Noteworthy volumes to be reirradiated must be established between the head and neck surgeon and the radiation oncologist: the definition of the clinical target volume should be taken into account, the natural history of recurrent tumors, especially with regard to extension modalities, and the absence of strict correlation between imaging and histological real extension. This is even more critical with the advent of new irradiation techniques. Chemotherapy associations and new radiosensitizing agents are also under investigation. Comparison between reirradiation modalities is difficult because most trials are phase 2 mono-institutional trials. As selection of patients is a key issue, only phase 3 multiinstitutional trials can provide definitive results.

    The aim of this preliminary study was to determine the prevalence of trismus in head and neck cancer patients treated with radiotherapy with or without concomitant chemotherapy and surgery. Patients with malignant lesions in the head and neck treated with curative intent were comprehensively evaluated for trismus using subjective and objective measures. A large proportion of the 70 patients recruited demonstrated moderate to severe subjective trismus (45.7%). Similarly, the vast majority of patients showed slight to severe trismus (91.4%) according to objective secondary outcome measures. Of these patients, 21 (65.6%) were also treated with concurrent chemoradiotherapy. When the radiation field involved the pterygoid muscles, 30 (93.8%) patients reported subjective trismus. Similarly, bilateral pterygoid muscle inclusion resulted in 28 (87.5%) patients with trismus. Trismus is a significantly prevalent consequence of treatment for head and neck cancer. Predictive factors include treatment with concurrent chemoradiotherapy and bilateral inclusion of the structures of mastication in the high-dose radiotherapy volume.

    Radiation and chemotherapy that are commonly used to treat human cancers damage cellular DNA. DNA damage appears to be more toxic to cancer cells than normal cells, most likely due to deregulated checkpoint activation and/or deficiency in DNA repair pathways that are characteristics of many tumors. However, unwanted side effects arise as a result of DNA damage to normal cells during the treatment.Here, we show that roscovitine, a cyclin-dependent kinase (CDK) inhibitor that inhibits CDK-1, CDK-2, CDK-5, CDK-7, and CDK-9 due to competitive binding to the ATP site on the kinases, causes significant DNA damage followed by p53-dependent cell death in human papilloma virus (HPV)-positive, but not in HPV-negative, head and neck cancer cells. Since HPV positivity was a molecular marker for increased sensitivity of cells to roscovitine, we reasoned that systemic roscovitine administration would not be toxic to healthy HPV-negative tissue. Indeed, low roscovitine doses significantly inhibited the growth of HPV-associated xenografted tumors in mice without causing any detectable side effects.Given that inhibition of CDKs has been shown to inhibit replication of several viruses, we suggest that roscovitine treatment may represent a selective and safe targeted therapeutic option against HPV-positive head and neck cancer.

    IMPORTANCE There is an immediate need to develop local intraoperative adjuvant treatment strategies to improve outcomes in patients with cancer who undergo head and neck surgery. OBJECTIVES To determine the safety of photodynamic therapy with 2-(1-hexyloxyethyl)-2-devinyl pyropheophorbide-a (HPPH) in combination with surgery in patients with head and neck squamous cell carcinoma. DESIGN, SETTING, AND PARTICIPANTS Nonrandomized, single-arm, single-site, phase 1 study at a comprehensive cancer center among 16 adult patients (median age, 65 years) with biopsy-proved primary or recurrent resectable head and neck squamous cell carcinoma. INTERVENTIONS Intravenous injection of HPPH (4.0 mg/m2), followed by activation with 665-nm laser light in the surgical bed immediately after tumor resection. MAIN OUTCOMES AND MEASURES Adverse events and highest laser light dose. RESULTS Fifteen patients received the full course of treatment, and 1 patient received HPPH without intraoperative laser light because of an unrelated myocardial infarction. Disease sites included larynx (7 patients), oral cavity (6 patients), skin (1 patient), ear canal (1 patient), and oropharynx (1 patient, who received HPPH only). The most frequent adverse events related to photodynamic therapy were mild to moderate edema (9 patients) and pain (3 patients). One patient developed a grade 3 fistula after salvage laryngectomy, and another patient developed a grade 3 wound infection and mandibular fracture. Phototoxicity reactions included 1 moderate photophobia and 2 mild to moderate skin burns (2 due to operating room spotlights and 1 due to the pulse oximeter). The highest laser light dose was 75 J/cm2. CONCLUSIONS AND RELEVANCE The adjuvant use of HPPH-photodynamic therapy and surgery for head and neck squamous cell carcinoma seems safe and deserves further study. PMID:23868427

    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.

    Food and nutrition play an important role in head and neck cancer (HNC) etiology; however, the role of carotenoids remains largely undefined. We explored the relation of HNC risk with the intake of carotenoids within the International Head and Neck Cancer Epidemiology Consortium. We pooled individual-level data from 10 case-control studies conducted in Europe, North America, and Japan. The analysis included 18,207 subjects (4414 with oral and pharyngeal cancer, 1545 with laryngeal cancer, and 12,248 controls), categorized by quintiles of carotenoid intake from natural sources. Comparing the highest with the lowest quintile, the risk reduction associated with total carotenoid intake was 39 % (95 % CI 29-47 %) for oral/pharyngeal cancer and 39 % (95 % CI 24-50 %) for laryngeal cancer. Intakes of β-carotene equivalents, β-cryptoxanthin, lycopene, and lutein plus zeaxanthin were associated with at least 18 % reduction in the rate of oral and pharyngeal cancer (95 % CI 6-29 %) and 17 % reduction in the rate of laryngeal cancer (95 % CI 0-32 %). The overall protective effect of carotenoids on HNC was stronger for subjects reporting greater alcohol consumption (p < 0.05). The odds ratio for the combined effect of low carotenoid intake and high alcohol or tobacco consumption versus high carotenoid intake and low alcohol or tobacco consumption ranged from 7 (95 % CI 5-9) to 33 (95 % CI 23-49). A diet rich in carotenoids may protect against HNC. Persons with both low carotenoid intake and high tobacco or alcohol are at substantially higher risk of HNC.

    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

    A robotic approach for thyroid surgery was developed to overcome the limitations of endoscopic thyroidectomy and provide many technical advantages. This approach facilitates the surgeon's control through a magnified three-dimensional view, decreased tremor, and freedom of motion with articulated instruments. Robotic thyroidectomy is safe and technically feasible in patients with well-differentiated, low-risk thyroid cancer. Furthermore, robotic thyroidectomy may become a good surgical alternative option for patients with more advanced thyroid cancer. Our modified bilateral axillo-breast approach (BABA) for central and lateral cervical neck lymph node (LN) dissection has yielded excellent surgical outcomes as an open procedure. The incorporation of robotics in thyroid cancer surgery will continue to evolve, and the surgical indications for robotic thyroidectomy will continue to expand. Further analyses that include long-term outcomes and randomized comparative trials remain important.

    Head and neck squamous cell carcinomas (HNSCCs) are the sixth most common cancer in the world. Despite significant advances in the treatment modalities involving surgery, radiotherapy, and concomitant chemoradiotherapy, the 5-year survival rate remained below 50% for the past 30 years. The worse prognosis of these cancers must certainly be link to the fact that HNSCCs strongly influence the host immune system. We present a critical review of our understanding of the HNSCC escape to the antitumor immune response such as a downregulation of HLA class I and/or components of APM. Antitumor responses of HNSCC patients are compromised in the presence of functional defects or apoptosis of T-cells, both circulating and tumor-infiltrating. Langerhans cells are increased in the first steps of the carcinogenesis but decreased in invasive carcinomas. The accumulation of macrophages in the peritumoral areas seems to play a protumoral role by secreting VEGF and stimulating the neoangiogenesis. PMID:21437225

    Irradiation mucositis is defined as an inflammatory-like process of the oropharyngeal mucosa following therapeutic irradiation of patients who have head and neck cancer. Clinically, it is a serious side effect because severe mucositis can cause generalized problems (weight loss, nasogastic tube feedings) and interferes with the well-being of the patient seriously. Grading mucositis is important for the evaluation of preventive and therapeutic measures. The object of this study was to develop a scoring method based on local mucositis signs only. Four clinical local signs of mucositis were used in this score: white discoloration, erythema, pseudomembranes and ulceration. Mucositis of the oral cavity was calcualted during conventional irradiation protocol for 8 distinguishable areas using the 4 signs and their extent. A prospective evaluation of this method in 15 irradiated head and neck cancer patients displayed an S-curve reflecting a symptomless first irradiation week, followed by a rapid and steady increase of white discoloration, erythema and pseudomembranes during the second and third week. Oral candidiasis, generalized symptoms such as weight loss and the highest mucositis scores were seen after 3 weeks irradiation. The novel mucositis scoring method may be of value in studying the effect of hygiene programs, topical application of disinfectans or antibiotics on oral mucositis. (author).

    Several questionnaires have been used to evaluate shoulder disability after neck dissection. The purpose of this study was to review these measures and highlight their strengths and weaknesses. A literature review was performed to identify measures of shoulder disability after head and neck cancer surgery. These measures were evaluated in terms of their methods of development and assessment of their psychometric properties. Seven questionnaires were identified. Several of the other questionnaires have been well developed but have not had their psychometric properties assessed in the head and neck cancer population. Each questionnaire has its strengths and weaknesses. The strengths and weaknesses of the shoulder disability questionnaires should be considered when deciding which questionnaire to use. Efforts should be focused on using well-designed questionnaires that have been assessed in this patient population rather than developing or using other questionnaires. © 2013 Wiley Periodicals, Inc.

    Most mouthwashes contain alcohol, a known cause of head and neck cancer (oral cavity, pharynx, larynx), likely through the carcinogenic activity of acetaldehyde, formed in the oral cavity from alcohol. We carried out a pooled analysis of 8981 cases of head and neck cancer and 10 090 controls from 12 case-control studies with comparable information on mouthwash use in the International Head and Neck Cancer Epidemiology Consortium. Logistic regression was used to assess the association of mouthwash use with cancers of the oral cavity, oropharynx, hypopharynx, and larynx, adjusting for study, age, sex, pack-years of tobacco smoking, number of alcoholic drinks/day, and education. Compared with never users of mouthwash, the odds ratio (OR) of all head and neck cancers was 1.01 [95% confidence interval (CI): 0.94-1.08] for ever users, based on 12 studies. The corresponding ORs of cancer of the oral cavity and oropharynx were 1.11 (95% CI: 1.00-1.23) and 1.28 (95% CI: 1.06-1.56), respectively. OR for all head and neck cancer was 1.15 (95% CI: 1.01-1.30) for use for more than 35 years, based on seven studies (P for linear trend=0.01), and OR 1.31 (95% CI: 1.09-1.58) for use more than one per day, based on five studies (P for linear trend <0.001). Although limited by the retrospective nature of the study and the limited ability to assess risks of mouthwash use in nonusers of tobacco and alcohol, this large investigation shows potential risks for head and neck cancer subsites and in long-term and frequent users of mouthwash. This pooled analysis provides the most precise estimate of the association between mouthwash use and head and neck cancer.

    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), <5 missing teeth, tooth brushing at least daily, and visiting a dentist ≥once a year. Logistic regression was used to estimate the effects of each 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 <5 missing teeth [odds ratio (OR) = 0.78; 95% confidence interval (CI) 0.74, 0.82], annual dentist visit (OR = 0.82; 95% CI 0.78, 0.87), daily tooth brushing (OR = 0.83, 95% CI 0.79, 0.88), and no gum disease (OR = 0.94; 95% CI 0.89, 0.99), and no association was observed for wearing dentures. These associations were relatively consistent across specific 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.

  6. Genome Stability Pathways in Head and Neck Cancers

    2013-01-01

    Full Text Available Genomic instability underlies the transformation of host cells toward malignancy, promotes development of invasion and metastasis and shapes the response of established cancer to treatment. In this review, we discuss recent advances in our understanding of genomic stability in squamous cell carcinoma of the head and neck (HNSCC, with an emphasis on DNA repair pathways. HNSCC is characterized by distinct profiles in genome stability between similarly staged cancers that are reflected in risk, treatment response and outcomes. Defective DNA repair generates chromosomal derangement that can cause subsequent alterations in gene expression, and is a hallmark of progression toward carcinoma. Variable functionality of an increasing spectrum of repair gene polymorphisms is associated with increased cancer risk, while aetiological factors such as human papillomavirus, tobacco and alcohol induce significantly different behaviour in induced malignancy, underpinned by differences in genomic stability. Targeted inhibition of signalling receptors has proven to be a clinically-validated therapy, and protein expression of other DNA repair and signalling molecules associated with cancer behaviour could potentially provide a more refined clinical model for prognosis and treatment prediction. Development and expansion of current genomic stability models is furthering our understanding of HNSCC pathophysiology and uncovering new, promising treatment strategies.

    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.)

    Cachexia is a profoundly debilitating wasting syndrome that affects patients with head and neck cancer and often contributes to their demise. A comprehensive literature search was performed up to April 2013 using PubMed, the Cochrane Library, CINAHL, and the Google search engine. For the meta-analyses, pooled prevalence estimates were calculated with a confidence interval of 95% (95% CI) by using random effects modeling. In this review, we outlined the unique challenges of cancer cachexia among patients with head and neck cancer by reviewing its impacts on quality of life (QOL), morbidity, and mortality. We explored the prevalence of different clinical markers of cachexia at the time of diagnosis and before and after treatment. Finally, we present updates regarding the diagnosis of cancer cachexia and recent findings, such as cardiac dysfunction that warrant clinical attention to more carefully identify patients at risk and potentially lead to better outcomes.

    Patients who underwent surgery for head and neck malignant neoplasms are problematic because dysphagia, pain and postoperative secuelaes. Nutritional support is necessary in more than 90% of all patients with head and neck cancer. The purpose of this study is to determine nutritional support in these patients and problems related to nutrition. Fifty-four patients with oral and pharyngolaryngeal carcinomas underwent surgery were studied prospectively. We studied nutritional support (oral nutrition, enteral nutrition or parenteral nutrition) and problems related to nutrition: aspiration neumoniae and pharyngostoma. The 7% of the patients underwent oral feeding after surgery, 87% enteral nutrition with nasogastric tube and 6% parenteral nutrition. We identified neumoniae in 6% of patients and faringocutaneous fistula in 19%. When patients leaved the hospital, 98% of the patients underwent oral feeding and one patient had nasopharyngeal tube for enteral nutrition. 1. Artificial nutrition was necessary in 93% patients with oropharyngolaryngealcancer; 2. Enteral nutrition was the most useful modality of alimentation (87%); 3.25% of patients had postoperative complications: (18% pharyngostoma, 6% neumoniae); 4. Oral feeding was possible in 98% of patients out of hospital.

    Individuals treated for head and neck cancer are at risk of sexual problems, particularly given the probability for disfigurement, body image disturbance, depressive symptoms, and functional difficulties that result from treatment. Because oncology nurses are an important source of information and support for patients, it is important that they be familiar with the current literature as well as opportunities for research. The aim of this study was to present a review of the literature on head and neck cancer and sexuality. PubMed, PsycINFO, CINAHL, and Ovid databases were searched using the terms "head and neck cancer" and "sexuality." Publications had to be peer-reviewed, empirical studies, written in English, and published within the last 10 years. Selected publications were compared based on study aims, leading investigator, study location, conceptual framework, study design, sample, instruments, and study findings. Nine publications were analyzed in this review. Incidence of individuals reporting a negative effect of head and neck cancer on sexuality varied from 24% to 100% depending on the study. There is a paucity of data regarding sexuality among patients with head and neck cancer. Existing studies indicate that sexuality is of considerable significance, particularly after treatment for head and neck cancer. Holistic care includes information about sexuality during and after treatment for head and neck cancer. Oncology nurses should be aware that this topic is of importance to many patients, and they should familiarize themselves with available resources. It is also important that nurse scientists facilitate research in the area of sexuality.

    From 1975 to 1985, 161 patients affected by head and neck cancer (58 oropharynx, 67 oral cavity, 36 paranasal sinuses) were treated with radiotherapy using an accelerated fractionation (AF) schedule at the University and Hospital Radiotherapy Departments of Florence. Five-year actuarial local control and survival was 38% for the oropharynx, 18% and 20% for the oral cavity, and 38% and 31% for the paranasal sinuses. Results were analysed according to T and N stage as well. Severe late sequelae were evaluated in 53 patients without local disease and with a minimum follow-up of one year: 8 patients developed osteonecrosis; there were 3 cases of trismus, 2 cases of laryngeal oedema, one case of blindness and one case of opththalmitis.

    Outcomes research is defined as clinical and population-based research that investigates the results of healthcare practices or interventions through the filter of the benefit to the patient and other stakeholders. Outcomes research is an increasingly important field or research, because of the pressing need for evidence-based information that can be used to make better informed health and healthcare decisions, and define desired health care practices in the current era of healthcare reform. This article will review the head and neck cancer (HNCA) outcomes literature published in the past year, with a focus on studies evaluating treatment and survival, short-term and long-term complications, and quality of life (QOL).

    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.

    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.

    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.

    Full Text Available BACKGROUND: The current study evaluated the association between tea consumption and head and neck cancer (HNC in Taiwan, where tea is a major agricultural product and a popular beverage. METHODS: Interviews regarding tea consumption (frequency, duration, and types were conducted with 396 HNC cases and 413 controls. Unconditional logistic regression was performed to estimate the odds ratio (OR and 95% confidence interval (CI of HNC risk associated with tea drinking, adjusted for sex, age, education, cigarette smoking, betel quid chewing, and alcohol drinking. RESULTS: A reduced HNC risk associated with tea drinking (OR for every cup per day = 0.96, 95% CI: 0.93-0.99; OR for ≧5 cups per day = 0.60, 95% CI: 0.39-0.94 was observed. The association was especially significant for pharyngeal cancer (OR for every cup per day = 0.93, 95% CI: 0.88-0.98; OR for ≧5 cups per day = 0.32, 95% CI: 0.16-0.66. A significant inverse association between HNC and tea consumption was observed particularly for green tea. CONCLUSIONS: This study suggests that tea drinking may reduce the risk of HNC. The anticancer property of tea, if proven, may offer a natural chemopreventive measure to reduce the occurrence of HNC.

    Nutrition-related complications of radiotherapy were evaluated in 74 head and neck cancer patients. Subjective changes of mouth dryness, taste, dysphagia, appetite, and food preferences were determined by questionnaire before and at weekly intervals during curative radiotherapy. Changes in body weight during therapy were also recorded. In addition, 24-hour dietary histories were taken from eight patients at the beginning and end of treatment. Results of the study indicate that patients were subjectively aware of nutritional problems prior to therapy and that therapy exacerbated these problems. As many as 25% of the patients experienced oral complications such as taste loss and/or dry mouth prior to initiation of radiotherapy. By the end of radiotherapy, over 80% of the patients were aware of oral and nutritional problems. Patients had an average weight loss of 5 kg prior to therapy; this loss of weight did not change during therapy. Diet histories of eight patients indicate significant caloric deficiencies early and late in radiotherapy. The oral and nutritional problems experienced by patients, even prior to therapy, support the idea that nutritional evaluation and maintenance are important not only during therapy, but prior to radiotherapy as well. Nutritional evaluation should be made a routine, integral part of therapy for every cancer patient.

    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.

    Head and neck cancers are one of the most frequent cancers worldwide. This paper attempts to evaluate disturbances of homeostasis of the necessary elements (calcium, magnesium, zinc, copper, iron, manganese) and changes in the levels of toxic metals (lead, cadmium, cobalt, chromium VI) in hair of patients with head and neck cancers, as well as people without a diagnosed neoplastic disease. In order to quantify the necessary elements and toxic metals, a method using ICP-MS and ICP-OES techniques had been developed and validated. The studies have shown that patients with head and neck cancer used to drink alcohol and smoked much more frequently than healthy individuals, both in the past and presently. Statistically significant differences in concentrations of average metal content in the group of patients with head and neck cancers compared to the control group were confirmed. Significant differences in metal content between the group of patients with head and neck cancers and healthy individuals were found which enabled distinguishing between the study groups. To this end, a more advanced statistical tool, i.e. chemometrics, was used. The conducted research analyses and the use of advanced statistical techniques confirm the benefits of using alternative material to distinguish the patients with head and neck cancers from the healthy individuals.

    Sinonasal cancers are rare and no high-level evidence exists to determine their optimal management. Prophylactic neck treatment issue remains controversial. The aim of this study was to analyze the pattern of neck failure and to identify any prognostic factors that may influence neck control. A retrospective review of 155 consecutive patients treated for sinonasal malignancy, without prophylactic neck treatment, between 1995 and 2005 at tertiary cancer center was performed. Demographic, clinical, morphological and pathological parameters were correlated with oncologic outcomes. Eight out of 155 patients (5%) presented initially with neck node metastasis. Complete remission was obtained for 133 patients after treatment completion. During follow up, 16 out of 133 patients (12%) were affected with regional recurrence. Neck failure occurred in 8 out of 51 patients with local failure and in 8 out of 82 patients locally controlled. Isolated nodal failure was observed in 5 patients initially cN0 out of 133 (3.8%) representing 7.3% of all recurrences and 3 of them underwent successful salvage therapy. None of the tested factors were significantly associated with neck control (p>0.05). Lymph node at diagnosis time was significantly and independently associated with poor survival (p=0.0012). Isolated neck relapse, when local control is achieved, is rare and salvage treatment is effective. Routine prophylactic neck treatment has little interest. However, this approach could be profitable to few selected patients, who remain to be defined. Further investigations are needed. Copyright © 2012 Elsevier Ltd. All rights reserved.

    The patient journey with head and neck cancer (HNC) is particularly challenging given the physical and functional impact of the cancer and treatment. The ability to perform activities of daily living can be severely compromised and have a profound impact on psychosocial well-being. These complex and long-lasting effects can affect patient quality of life for months to years and the literature shows that information for HNC patients is often insufficient. This observational cross-sectional study utilized survey methodology to investigate the informational needs of HNC patients and the preferred modalities for delivery. This was done to inform the development of resources for HNC patients. Four hundred fifty surveys were analyzed. The median age was 61 years and 58% of the cohort was born in Canada. Most were Caucasian (72%), Chinese being the next largest ethnicity (12%). A third had less than high school education and most had cancer of the oral cavity (28%) and were in long-term follow-up (41%). Comparison of the percentage of items to which a patient responded "very important" across the six domains shows variation of importance by domain (overall mixed effects regression model p < 0.0001). Additionally, each domain was compared to the medical domain and all had significantly lower mean scores (all p < 0.0001) with the medical domain scoring highest (mean score 64.6). The top preferred education modalities were teaching with a healthcare professional and pamphlets. This study highlights the type of information that HNC patients want and the format they wish to receive it in. The design provides a comprehensive way to consult with patients toward building education that responds to their specific needs.

    Head and neck squamous cell carcinoma(HNSCC) is the sixth most common cancer worldwide, and is responsible for a quarter of a million deaths annually. The survival rate for HNSCC patients is poor, showing only minor improvement in the last three decades. Despite new surgical techniques and chemotherapy protocols, tumor resistance to chemotherapy remains a significant challenge for HNSCC patients. Numerous mechanisms underlie chemoresistance, including genetic and epigenetic alterations in cancer cells that may be acquired during treatment and activation of mitogenic signaling pathways, such as nuclear factor kappa-light-chain-enhancer-of activated B cell, that cause reduced apoptosis. In addition to dysfunctional molecular signaling, emerging evidence reveals involvement of cancer stem cells(CSCs) in tumor development and in tumor resistance to chemotherapy and radiotherapy. These observations have sparked interest in understanding the mechanisms involved in the control of CSC function and fate. Post-translational modifications of histones dynamically influence gene expression independent of alterations to the DNA sequence. Recent findings from our group have shown that pharmacological induction of posttranslational modifications of tumor histones dynamically modulates CSC plasticity. These findings suggest that a better understanding of the biology of CSCs in response to epigenetic switches and pharmacological inhibitors of histone function may directly translate to the development of a mechanism-based strategy to disrupt CSCs. In this review, we present and discuss current knowledge on epigenetic modifications of HNSCC and CSC response to DNA methylation and histone modifications. In addition, we discuss chromatin modifications and their role in tumor resistance to therapy.

    Most studies, primarily conducted in populations of European ancestry, reported increased risk of head and neck cancer (HNC) associated with leanness (body mass index [BMI] 30 kg/m(2), respectively), compared with normal weight (18.5 to Cancer Epidemiology Study is a population-based, racially diverse case-control study of 1289 incident HNC cases (330 African Americans) and 1361 controls (261 African Americans). Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated for associations between BMI 1 year prediagnosis and HNC risk stratified by race and adjusted for age, sex, smoking, alcohol, and education. Multiplicative interaction between BMI and race was evident (Pint = .00007). Compared with normal weight, ORs for leanness were increased for African Americans (OR, 3.91; 95% CI, 0.72-21.17) and whites (OR, 1.48; 95% CI, 0.60-3.65). For overweight and obesity, ORs were decreased in African Americans (OR, 0.51; 95% CI, 0.32-0.83 and OR, 0.47; 95% CI, 0.28-0.79, respectively) but in not whites. The increased risk associated with leanness was greater for smokers than nonsmokers (Pint = .02). These data, which require replication, suggest that leanness is associated with increased HNC risk among African Americans to a greater extent than whites and overweight and obesity is associated with decreased HNC risk only among African Americans.

    Patients undergoing radiotherapy or chemoradiotherapy treatment for head and neck cancer have an increased risk of malnutrition, and may require enteral feeding via nasogastric or gastrostomy tube. The aim of this audit was to examine current enteral feeding practice, mortality, morbidity and 6-month outcome data of head and neck cancer patients receiving radical (chemo)radiotherapy at a regional cancer centre and to compare the results with a regional head and neck cancer gastrostomy audit. A 2-year audit was conducted (2006-2008). Inclusion criteria were all adult patients diagnosed with squamous cell carcinoma of the head and neck, receiving radical radiotherapy or chemoradiotherapy treatment. The first-year data were collected retrospectively, and the second-year data were collected prospectively. Data were collected on all patients requiring enteral feeding with 6-month outcome data relating to route of nutrition. Approximately 14% (n = 32/223) of patients were admitted for nasogastric feeding as a result of inadequate oral alimentation. On admission, 94% were at risk of refeeding syndrome, taking a mean (SD) of 11 (4.9) days to reach full nutritional requirements. Mean (SD) length of hospital stay was 13 (5.1) days. No major complications from nasogastric tube insertion were found. The mean (SD) length of nasogastric feeding was 72 (20.1) days with 89.6% managing full nutritional requirements orally at 6 months. Patients requiring enteral feeding during treatment were fed via a nasogastric tube, rather than via a prophylactic gastrostomy tube. Compared with the regional gastrostomy audit results, our patients had a lower clinical risk/complication rate, with a greater proportion tolerating full oral intake at 6 months. Therefore, nasogastric feeding, rather than prophylactic gastrostomy tube feeding, could be a more appropriate method of enteral feeding in this patient group. © 2013 University Hospital Southampton Journal of Human Nutrition and Dietetics

    2009-01-01

    Full Text Available Patients with head and neck squamous cell carcinoma (HNSCC are at considerable risk for death, with 5-year relative survival rates of approximately 60%. The profound multifaceted deficiencies in cell-mediated immunity that persist in most patients after treatment may be related to the high rates of treatment failure and second primary malignancies. Radiotherapy and chemoradiotherapy commonly have severe acute and long-term side effects on immune responses. The development of immunotherapies reflects growing awareness that certain immune system deficiencies specific to HNSCC and some other cancers may contribute to the poor long-term outcomes. Systemic cell-mediated immunotherapy is intended to activate the entire immune system and mount a systemic and/or locoregional antitumor response. The delivery of cytokines, either by single cytokines, for example, interleukin-2, interleukin-12, interferon-, interferon-, or by a biologic mix of multiple cytokines, such as IRX-2, may result in tumor rejection and durable immune responses. Targeted immunotherapy makes use of monoclonal antibodies or vaccines. All immunotherapies for HNSCC except cetuximab remain investigational, but a number of agents whose efficacy and tolerability are promising have entered phase 2 or phase 3 development.

    From May 1994 to May 1997, 52 patients with locally advanced head and neck cancer were treated with accelerated hyperfractionated irradiation (1.6 Gy, twice daily, 10 times a week, with minimum interval of 6 hours between fractions and the total dose to 67.2-70.4 Gy) and concomitant use of daily low-dose Carboplatin. The median follow-up period was 19.8 months with a range of 2-44 months. Complete response rate was 73% (38/52). Cumulative survival rate at 3 years was 46.7% and the relapse rate was 21.1% (8/38). The relapse sites were as follows, primary site; 2 cases, lymphnodes; 4 cases and distant metastases; 2 cases. The major acute toxicity was stomatitis. Grade 3-4 late sequelae was observed in 7 cases. Grade 3 xerostomia was observed in 2 cases, esophageal stenosis was observed in 2 cases and arytenoid necrosis was observed in 2 cases. There were no fatal sequelae. Acute sequelae are very variable and it will be necessary to individualize the treatment time according to the state of their stomatitis. (author)

    Full Text Available Head and neck cancer is the commonest cancer in India and consists of about one-third of all cancers. Among viral infections, Epstein Barr virus (EBV has been implicated in the association of many head and neck cancers. Role of EBV as etiological factor in our population remains unknown. AIMS & OBJECTIVES: To determine the EBV related etiology of mucosal Head and Neck Squamous Cell Carcinoma (HNSCC in Kashmir Valley and if positive to define sub-typing of EBV and to find a correlation between the burden of EBV and disease status. MATERIAL METHODS: Observational single centre retrospective –prospective study. The study included 53 tissue samples from patients with Squamous Cell carcinoma of Head and Neck region. An equal number of blood samples were taken from healthy volunteers as a control for the reaction process. Sample collection and storage was done as per standard protocol. DNA amplification was done by Polymerase chain reaction. RESULTS: We did not observe any sample which tested positive for EBV. All samples were negative for EBV DNA. CONCLUSION: EBV has no role in the pathogenesis of Head and Neck Cancers in Kashmiri ethnic population of India. Different Genetic makeup of our population may be responsible for it. Further studies are needed to elucidate the etiology of head and neck Carcinoma in our population.

    Full Text Available Background: Head and Neck cancers are basically squamous cell carcinomas. It is the fifth most common cancer and the sixth most common cause of cancer mortality in the world. Incidence of cancer as a whole for all sites is fourth highest in Kamrup Urban District (KUD in males (AAR 185.2 and second highest (AAR 156.3 in females out of all Population Based Cancer Registries (PBCR in India. Incidence of head and neck cancers in KUD is quite high both nationally and internationally. This retrospective study was carried out to assess the incidence pattern of head and neck cancers in Kamrup Urban District of Assam, India for the period of 2009-2011. Methods: Cancer is not notifiable in India, so method of collecting information on cancer was active in PBCR Guwahati. A total of 4416 cases were registered during the three years (1st January 2009- 31st December 2011 of which 2508 were male and 1908 female. Statistical analysis used: Age Adjusted Rate (AAR, Crude Rate (CR and Population pyramids are provided by NCRP-ICMR. Results: The relative proportion of head and neck cancers of total cancer cases registered in KUD constitutes 26% (654/2508 and 12% (225/1908 in male and female respectively. In males cancer of hypopharynx (AAR 14.7 was most common followed by tongue (AAR 9.4 and mouth (AAR 7.7. In females cancer of mouth (AAR 7.6 is most common followed by cancer of tongue (AAR 3.2. Conclusion: The pattern and incidence of various head and neck cancers is of utmost importance for primary prevention and early detection to adequately manage these cancers comprehensively in the community.

    The pathophysiology of cancer cachexia remains complex. A comprehensive literature search was performed up to April 2013 using PubMed, the Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, and the Google search engine. In this review, we focus on the different mediators of impaired anabolism and upregulated catabolism that alter the skeletal muscle homeostasis resulting in the wasting of cancer cachexia. We present recent evidence of targeted treatment modalities from clinical trials along with their potential mechanisms of action. We also report on the most current evidence from randomized clinical trials using multimodal treatments in patients with cancer cachexia, but also the evidence from head and neck cancer-specific trials. A more complete understanding of the pathophysiology of the syndrome may lead to more effective targeted therapies and improved outcomes for patients.

    2017-07-01

    The main purpose of the TNM system is to provide an anatomic-based classification to adequately depict cancer prognosis. Accurate cancer staging is important for treatment selection and outcome prediction, research design, and cancer control activities. To maintain clinical relevance, periodical updates to TNM are necessary. The recently published 8th edition TNM classification institutes the following changes to the staging of head and neck (excluding thyroid cancer): new stage classifications [HPV-related oropharyngeal cancer (HPV+ OPC) and soft tissue sarcoma of the head and neck (HN-STS)] and modification of T and N categories [T and N categories for nasopharyngeal cancer (NPC), T categories for oral cavity squamous cell carcinomas (OSCC), N categories for non-viral related head and neck cancer and unknown primary (CUP), and T categories for head and neck cutaneous carcinoma]. These changes reflect better understanding tumor biology and clinical behavior (e.g., HPV+ OPC and HN-STS), improved outcomes associated with technical advances in diagnosis and treatment (e.g., NPC), evolving knowledge about additional prognostic factors and risk stratification from research and observation (e.g., inclusion of depth of invasion variable for OSCC, inclusion of extranodal extension variable for all non-viral head and neck cancer, and reintroduction of size criteria for non-Merkel cell cutaneous carcinoma of the head and neck). This review summarizes the changes and potential advantages and limitations/caveats associated with them. Further evidence is needed to evaluate whether these changes would result in improvement in TNM stage performance to better serve the needs for clinical care, research, and cancer control.

    The goal of this work was to evaluate the efficacy and toxicity of hyperfractionated stereotactic reirradiation (re-RT) as a treatment for inoperable, recurrent, or second primary head and neck squamous cell cancer (HNSCC) that is not suitable for systemic treatment. Forty patients with recurrent or second primary HNSCC were included in this study. The patients had a median gross tumor volume of 76 ml (range 14-193 ml) and a previous radiotherapy dose greater than 60 Gy. Treatment was designed to cover 95 % of the planning target volume (PTV, defined as gross tumor volume [GTV] + 3 mm to account for microscopic spreading, with no additional set-up margin) with the prescribed dose (48 Gy in 16 fractions b.i.d.). Treatment was administered twice daily with a minimum 6 h gap. Uninvolved lymph nodes were not irradiated. Treatment was completed as planned for all patients (with median duration of 11 days, range 9-14 days). Acute toxicity was evaluated using the RTOG/EORTC scale. A 37 % incidence of grade 3 mucositis was observed, with recovery time of ≤ 4 weeks for all of these patients. Acute skin toxicity was never observed to be higher than grade 2. Late toxicity was also evaluated according to the RTOG/EORTC scale. Mandible radionecrosis was seen in 4 cases (10 %); however, neither carotid blowout syndrome nor other grade 4 late toxicity occurred. One-year overall survival (OS) and local progression-free survival (L-PFS) were found to be 33 and 44 %, respectively. Performance status and GTV proved to be significant prognostic factors regarding local control and survival. Hyperfractionated stereotactic re-RT is a reasonable treatment option for patients with recurrent/second primary HNSCC who were previously exposed to high-dose irradiation and who are not candidates for systemic treatment or hypofractionation.

    Full Text Available Abstract Head and neck (HN cancer represents one of the most challenging diseases because the mortality remains high despite advances in early diagnosis and treatment. Although vaccine-based approaches for the treatment of advanced squamous cell carcinoma of the head and neck have achieved limited clinical success, advances in cancer immunology provide a strong foundation and powerful new tools to guide current attempts to develop effective cancer vaccines. This article reviews what has to be rather what has been done in the field for the development of future vaccines in HN tumours.

  12. EXTRACAPSULAR SPREAD IN IPSILATERAL NECK METASTASIS: AN IMPORTANT PROGNOSTIC FACTOR IN LARYNGEAL CANCER

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    Objective To evaluate the impact of extracapsular spread (ECS) in ipsilateral neck metastasis on prognosis and its related factors in laryngeal cancer.Methods The study included 184 patients who underwent laryngectomy and simultaneous radical or modified radical neck dissection between January 1994 and December 1997 for laryngeal cancer. All of them had a complete 5-year follow-up. We used transparent lymph node detection and continuous slicing method on all neck dissection specimens.Kaplan-Meier model was used for survival analysis and the log-rank test was used to assess significance.Results We found pathological neck metastases in 80 patients. Among them, 26 cases (32.5%) had ECS in ipsilateral neck. ECS incidence increased with advanced pathological N (pN) stages (pN1 3.7%, pN2a 25.0%, pN2b 50. 0%, and pN2c 55.6%; P=0.001). ECS incidence also increased with number of positive nodes ( 1 positive node 8.6%, 2 positive nodes 33.3%, 3 and more positive nodes 66. 7%; P<0.001). Incidences of contralateral neck metastases and ipsilateral neck recurrence in patients with ECS were higher than those in patients without ECS (46.2%vs.24. 1%, P=0 046; 34. 6% vs. 7.4%, P =0. 002). The 5-year survival rate of patients with ECS was significantly lower than that of patients without ECS (23.1% vs. 57.4%,P=0.013).Conclusion ECS is an important prognostic factor in laryngeal cancer. Patients with ECS have a higher incidence of contralateral neck metastasis, so bilateral neck dissection should be selected.

  13. The Role of Prophylactic Central Neck Dissection in the Treatment of Differentiated Thyroid Cancer

    2016-01-01

    Full Text Available The utility and efficacy of prophylactic central neck dissection with total thyroidectomy for the treatment of differentiated thyroid cancer has been debated in the literature over the past few decades. Proponents of prophylactic central neck dissection support its routine use with the notion that it reduces local recurrence, increases accuracy in TNM staging, and reduces surgical morbidity associated with reoperation. Conversely, those against the use of routine prophylactic central neck dissection argue there is no clear evidence which shows a reduction in recurrence or added benefit to survival, while the procedure increases the risk for complications and morbidity. This article discusses the role of prophylactic central neck dissection in the setting of thyroid cancer and reviews recently published literature to evaluate efficacy and safety of this procedure.

    1993-10-01

    To establish a genetic model of the progression of head and neck squamous carcinoma we have defined the incidence and timing of p53 mutations in this type of cancer. We sequenced the conserved regions of the p53 gene in 102 head and neck squamous carcinoma lesions. These included 65 primary invasive carcinomas and 37 noninvasive archival specimens consisting of 13 severe dysplasias and 24 carcinoma in situ lesions. The incidence of p53 mutations in noninvasive lesions was 19% (7/37) and increased to 43% (28/65) in invasive carcinomas. These data suggest that p53 mutations can precede invasion in primary head and neck cancer. Furthermore, the spectrum of codon hotspots is similar to that seen in squamous carcinoma of the lung and 64% of mutations are at G nucleotides, implicating carcinogens from tobacco smoke in the etiology of head and neck squamous carcinoma.

    1996-07-01

    From October 1990 to March 1994, 90 patients entered a prospectively randomised trial in head and neck cancer. All patients had verified squamous cell carcinoma and were referred for primary radiation therapy. Tumours originated in the oral cavity in 25, oropharynx in 37, larynx in 15 and hypopharynx in 13 cases. Patients' stages were predominantely T3 and T4 (71/90) and had lymph node metastases (60/90). Seventy-nine male patients and 11 female patients, with a median age of 57 years (range 37-76 years) were treated. Patients were randomised to one of three treatment options: conventional fractionation (CF) consisting of 70 Gy in 35 fractions over 7 weeks or continuous hyperfractionated accelerated radiation therapy (Vienna-CHART) or Vienna-CHART with administration of a single dose of mitomycin C on day 5 of treatment (V-CHART + MMC). By the accelerated regimen a total dose of 55.3 Gy was given in 33 fractions within 17 consecutive days. Acute mucositis was the main toxicity recorded in those patients treated by accelerated fractionation, although the overall duration of mucosal reaction did not differ in the three treatment groups. There was no influence on local toxicity if MMC was added to radiation therapy or not. Those patients treated with additional MMC experienced a grade III/IV haematological toxicity in 4/28 cases. Complete remission (CR) was recorded in 48% following CF, 79% after Vienna-CHART (P < 0.05) and 71% after Vienna-CHART + MMC. The overall local failure rates were 73%, 59% and 42% (P = NS) for patients treated by CF, Vienna-CHART and Vienna-CHART + MMC respectively.

    The possible role of dietary fiber in the etiology of head neck cancers (HNCs) is unclear. We used individual-level pooled data from ten case-control studies (5959 cases and 12,248 controls) participating in the International Head and Neck Cancer Epidemiology (INHANCE) consortium, to examine the association between fiber intake and cancer of the oral cavity/pharynx and larynx. Odds Ratios (ORs) and their 95% Confidence Intervals (CIs) were estimated using unconditional multiple logistic regression applied to quintile categories of non-alcohol energy-adjusted fiber intake and adjusted for tobacco and alcohol use and other known or putative confounders. Fiber intake was inversely associated with oral and pharyngeal cancer combined (OR for 5th vs. 1st quintile category = 0.49, 95% CI: 0.40-0.59; p for trend <0.001) and with laryngeal cancer (OR = 0.66, 95% CI: 0.54-0.82, p for trend <0.001). There was, however, appreciable heterogeneity of the estimated effect across studies for oral and pharyngeal cancer combined. Nonetheless, inverse associations were consistently observed for the subsites of oral and pharyngeal cancers and within most strata of the considered covariates, for both cancer sites. Our findings from a multicenter large-scale pooled analysis suggest that, although in the presence of between-study heterogeneity, a greater intake of fiber may lower HNC risk. © 2017 UICC.

    Recent advances have permitted successful therapeutic targeting of the immune system in head and neck squamous cell carcinoma (HNSCC). These new immunotherapeutic targets and agents are being rapidly adopted by the oncologic community and hold considerable promise. The National Cancer Institute sponsored a Clinical Trials Planning Meeting to address the issue of how to further investigate the use of immunotherapy in patients with HNSCC. The goals of the meeting were to consider phase 2 or 3 trial designs primarily in 3 different patient populations: those with previously untreated, human papillomavirus-initiated oropharyngeal cancers; those with previously untreated, human papillomavirus-negative HNSCC; and those with recurrent/metastatic HNSCC. In addition, a separate committee was formed to develop integrative biomarkers for the clinical trials. The meeting started with an overview of key immune components and principles related to HNSCC, including immunosurveillance and immune escape. Four clinical trial concepts were developed at the meeting integrating different immunotherapies with existing standards of care. These designs were presented for implementation by the head and neck committees of the National Cancer Institute-funded National Clinical Trials Network. This article summarizes the proceedings of this Clinical Trials Planning Meeting, the purpose of which was to facilitate the rigorous development and design of randomized phase 2 and 3 immunotherapeutic trials in patients with HNSCC. Although reviews usually are published immediately after the meeting is held, this report is unique because there are now tangible clinical trial designs that have been funded and put into practice and the studies are being activated to accrual.

    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.

    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.

    The IGF system has been shown to have either negative or negligible impact on clinical outcomes of tumor development depending on specific tumor sites or stages. This review focuses on the clinical impact of IGF signaling in head and neck cancer, the effects of IGF targeted therapies, and the multi-dimensional role of IRS 1/2 signaling as a potential mechanism in resistance to targeted therapies. Similar to other tumor sites, both negative and positive correlations between levels of IGF-1/IGF-1-R and clinical outcomes in head and neck cancer have been reported. In addition, utilization of IGF targeted therapies has not demonstrated significant clinical benefit; therefore the prognostic impact of the IGF system on head and neck cancer remains uncertain.

    Chemical carcinogens derived from cigarettes and other tobacco products, as well as betel quid, paan, and alcohol consumption, are commonly associated with head and neck cancer risk. This is a particularly debilitating cancer, with a high recurrence rate and long-term treatment comorbidities affecting health and lifestyle. Controlling tobacco access or use may be an ideal prevention strategy but may also be challenging or undesired. Individuals, however, may be able to reduce their risk through simple and focused dietary change. Results from epidemiologic studies, basic research, and clinical investigations suggest that a diet rich in cruciferous vegetables may increase carcinogen metabolism, induce apoptosis, and reduce the risk of developing a primary head and neck tumor. This review briefly summarizes head and neck cancer nutritional epidemiology, and then describes the biochemical and epidemiologic literature describing the effects of crucifer consumption on head and neck carcinogenesis. To translate these findings, the strengths and limitations of specific intervention models are discussed, including differences in target populations and the choice of a food-based or pill-based approach for intervention. Addressing these factors in a future intervention may define a low-cost and non-toxic approach to reduce the burden of head and neck cancer.

    Evidence for the possible effect of vitamin E on head and neck cancers (HNCs) is limited. We used individual-level pooled data from 10 case-control studies (5959 cases and 12 248 controls) participating in the International Head and Neck Cancer Epidemiology (INHANCE) consortium to assess the association between vitamin E intake from natural sources and cancer of the oral cavity/pharynx and larynx. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using unconditional logistic regression models applied to quintile categories of non-alcohol energy-adjusted vitamin E intake. Intake of vitamin E was inversely related to oral/pharyngeal cancer (OR for the fifth vs the first quintile category=0.59, 95% CI: 0.49-0.71; P for trend <0.001) and to laryngeal cancer (OR=0.67, 95% CI: 0.54-0.83, P for trend <0.001). There was, however, appreciable heterogeneity of the estimated effect across studies for oral/pharyngeal cancer. Inverse associations were generally observed for the anatomical subsites of oral and pharyngeal cancer and within covariate strata for both sites. Our findings suggest that greater vitamin E intake from foods may lower HNC risk, although we were not able to explain the heterogeneity observed across studies or rule out certain sources of bias.

    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.

    This paper attempts to chart the history of head and neck cancers and their surgical treatment, starting from ancient Egypt and concluding with Galen. The ancient Egyptians appear to have treated head and neck cancers with local applications. The ancient Greek corpus contains a reference to treating pharyngeal carcinoma with cautery, but the description is too vague to establish the diagnosis conclusively. The ancient Romans moved away from surgical treatments, with Galen establishing a prejudice against surgery that would last through the Middle Ages.

    Head-and-neck cancer is a major form of the disease worldwide. Treatment consists of surgery, radiation therapy and chemotherapy, but these have not resulted in improved survival rates over the past few decades. Versatile nanoparticles, with selective tumor targeting, are considered to have the potential to improve these poor outcomes. Application of nanoparticle-based targeted therapeutics has extended into many areas, including gene silencing, chemotherapeutic drug delivery, radiosensitization, photothermal therapy, and has shown much promise. In this review, we discuss recent advances in the field of nanoparticle-mediated targeted therapeutics for head-and-neck cancer, with an emphasis on the description of targeting points, including future perspectives.

    Full Text Available In this study, magnetic iron oxide nanoparticle induced hyperthermia is applied for treatment of head and neck cancer using a mouse xenograft model of human head and neck cancer (Tu212 cell line. A hyperthermia system for heating iron oxide nanoparticles was developed by using alternating magnetic fields. Both theoretical simulation and experimental studies were performed to verify the thermotherapy effect. Experimental results showed that the temperature of the tumor center has dramatically elevated from around the room temperature to about 40oC within the first 5-10 minutes. Pathological studies demonstrate epithelial tumor cell destruction associated with the hyperthermia treatment.

    Cigar and pipe smoking are considered risk factors for head and neck cancers, but the magnitude of effect estimates for these products has been imprecisely estimated. By using pooled data from the International Head and Neck Cancer Epidemiology (INHANCE) Consortium (comprising 13,935 cases and 18,691 controls in 19 studies from 1981 to 2007), we applied hierarchical logistic regression to more precisely estimate odds ratios and 95% confidence intervals for cigarette, cigar, and pipe smoking separately, compared with reference groups of those who had never smoked each single product. Odds ratios for cigar and pipe smoking were stratified by ever cigarette smoking. We also considered effect estimates of smoking a single product exclusively versus never having smoked any product (reference group). Among never cigarette smokers, the odds ratio for ever cigar smoking was 2.54 (95% confidence interval (CI): 1.93, 3.34), and the odds ratio for ever pipe smoking was 2.08 (95% CI: 1.55, 2.81). These odds ratios increased with increasing frequency and duration of smoking (Ptrend ≤ 0.0001). Odds ratios for cigar and pipe smoking were not elevated among ever cigarette smokers. Head and neck cancer risk was elevated for those who reported exclusive cigar smoking (odds ratio = 3.49, 95% CI: 2.58, 4.73) or exclusive pipe smoking (odds ratio = 3.71, 95% CI: 2.59, 5.33). These results suggest that cigar and pipe smoking are independently associated with increased risk of head and neck cancers. PMID:23817919

    Background Sexual contact may be the means by which head and neck cancer patients are exposed to human papillomavirus (HPV). Methods We undertook a pooled analysis of four population-based and four hospital-based case–control studies from the International Head and Neck Cancer Epidemiology (INHANCE) consortium, with participants from Argentina, Australia, Brazil, Canada, Cuba, India, Italy, Spain, Poland, Puerto Rico, Russia and the USA. The study included 5642 head and neck cancer cases and 6069 controls. We calculated odds ratios (ORs) of associations between cancer and specific sexual behaviours, including practice of oral sex, number of lifetime sexual partners and oral sex partners, age at sexual debut, a history of same-sex contact and a history of oral–anal contact. Findings were stratified by sex and disease subsite. Results Cancer of the oropharynx was associated with having a history of six or more lifetime sexual partners [OR = 1.25, 95% confidence interval (CI) 1.01, 1.54] and four or more lifetime oral sex partners (OR = 2.25, 95% CI 1.42, 3.58). Cancer of the tonsil was associated with four or more lifetime oral sex partners (OR = 3.36, 95 % CI 1.32, 8.53), and, among men, with ever having oral sex (OR = 1.59, 95% CI 1.09, 2.33) and with an earlier age at sexual debut (OR = 2.36, 95% CI 1.37, 5.05). Cancer of the base of the tongue was associated with ever having oral sex among women (OR = 4.32, 95% CI 1.06, 17.6), having two sexual partners in comparison with only one (OR = 2.02, 95% CI 1.19, 3.46) and, among men, with a history of same-sex sexual contact (OR = 8.89, 95% CI 2.14, 36.8). Conclusions Sexual behaviours are associated with cancer risk at the head and neck cancer subsites that have previously been associated with HPV infection. PMID:20022926

    To characterize the safety profile and effectiveness of esophageal dilation in head and neck cancer patients. A systematic review was undertaken for articles reporting outcomes of esophageal dilation in head and neck cancer patients. The Medline, Scopus, Web of Science, and Cochrane databases were searched in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Complications related to esophageal dilation in head and neck cancer patients was the primary outcome of interest. Success rates, demographic data, cancer staging, and treatment data were assessed secondarily. Statistical analyses included both qualitative and quantitative assessments. A limited meta-analysis and pooling of the data was performed using a random effects model. Of the collective 8,243 initial candidate articles, 15 retrospective studies containing data for a collective 449 patients were ultimately included in the analysis. There was significant heterogeneity in the outcomes data. With an overall complication rate of 10.6% (95% confidence interval [CI]: 4.1%,17%) and a pooled success rate of 72.9% (95% CI: 65.7%,80.1%) per patient, the articles generally supported the use of dilation. Head and neck cancer patients experience a higher rate of complications following dilation compared to patients with other causes of benign stricture. Esophageal dilation is effective in improving dysphagia, but these benefits are often transient and thus necessitate repeat interventions.

    2016-10-01

    Full Text Available Background: Head and neck cancer severely affects the voice and compromises a patient’s vocal independence. In the present study we have investigated the difference in three vital components of the voice - pitch, jitter, and shimmer in head and neck cancer patients and compared the findings with age matched healthy volunteers. Methods: Voice parameters were ascertained in newly diagnosed head and neck cancer patients and controls using voice analysis software (PRAAT and a Dynamic Unidirectional AUD-59 XLR microphone in a sound proof voice recording laboratory. Results: We observed considerable changes in the three voice indices of pitch, jitter and shimmer. According to gender, there were significant changes in all three indices for men (P<0.015 to 0.0001, whereas only pitch significantly changed in women (P=0.0001. Conclusion: The results have suggested that individuals with any form of head and neck cancer will have a degree of voice problems even before the initiation of cancer treatments. Voice assessment is a vital aspect to be considered before initiation of treatment.

    Metals are known for playing essential roles in human physiology. Copper and zinc are trace elements closely dependent on one another and are involved in cell proliferation, growth, gene expression, apoptosis and other processes. Their homeostasis is crucial and tightly controlled by a resourceful system of transporters and transport proteins which deliver copper and zinc ions to their target sites. Abnormal zinc and copper homeostasis can be seen in a number of malignancies and also in head and neck cancer. Imbalance in this homeostasis is observed as an elevation or decrease of copper and zinc ions in serum or tissue levels in patients with cancer. In head and neck cancer these altered levels stand out from those of other malignancies which makes them an object of interest and therefore zinc and copper ions might be a good target for further research of head and neck cancer development and progression. This review aims to summarize the physiological roles of copper and zinc, its binding and transport mechanisms, and based on those, its role in head and neck cancer. To provide stronger evidence, dysregulation of levels is analysed by a meta-analytical approach.

    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.

    2015-05-01

    The purpose of this study was to determine the actual degree of shoulder muscle change and its relation to symptoms after neck dissection for head and neck cancers. Forty-two patients who underwent unilateral neck dissection were selected. Data obtained from each subject were trapezius muscle volume ratio and a Shoulder Disability Questionnaire (SDQ) score. Patients who had undergone neck dissection with spinal accessory nerve (SAN) preservation were compared with those who had received radical neck dissection. The preservation group was further separated into subgroups by the extent of neck dissection. Trapezius muscle volume ratio was higher and SDQ score was significantly lower in the SAN preservation group compared to the radical neck dissection group. However, the SAN preservation subgroups did not differ from each other. In addition, a good correlation between the muscle volume ratio and SDQ score was observed. With trapezius muscle volume ratio, clinicians may be able to diagnose shoulder dysfunction after neck dissection. Further research on the subject is warranted. This suggests a novel strategy for assessing the degree of shoulder dysfunction. © 2014 Wiley Periodicals, Inc.

    Full Text Available Didier Dequanter, Mohammad Shahla, Pascal Paulus, Philippe H LothaireDepartment of Surgery, CHU Charleroi (Hopital Andre Vésale, Montigny le Tilleul, BelgiumAbstract: With its targeted mechanism of action and synergistic activity with current treatment modalities, cetuximab is a potentially valuable treatment option for patients with recurrent and/or metastatic squamous cell cancer of the head and neck who have progressed on cisplatin-based chemotherapy. The use of cetuximab in combination with radiotherapy as definitive treatment for locoregionally advanced squamous cell cancer of the head and neck is generally restricted to patients unfit to receive cisplatin-based chemoradiation, which is still considered the standard of care. The effect of this epidermal growth factor receptor antagonist occurs without any change in the pattern and the severity of toxicity usually associated with head and neck radiation.Keywords: cetuximab, SCCHN, radiotherapy

    Full Text Available Background: Reconstruction with microvascular free flaps is considered the reconstructive option of choice in cancer of the head and neck regions and breast. Rarely, there is paucity of vessels, especially the veins, at the recipient site. The cephalic vein with its good caliber and constant anatomy is a reliable recipient vein available in such situations. Materials and Methods: It is a retrospective study from January 2010 to July 2012 and includes 26 patients in whom cephalic vein was used for free-flap reconstruction in head and neck (3 cases and breast cancers (23 cases. Results: All flaps in which cephalic vein was used survived completely. Conclusion: Cephalic vein can be considered as a reliable source of venous drainage when there is a non-availability/unusable of veins during free-flap reconstruction in the head and neck region and breast and also when additional source of venous drainage is required in these cases.

    Our aim was to survey the factors affecting access to cancer care in patients with head and neck cancer after Hurricane Katrina. In this cross-sectional survey, 207 patients with head and neck cancer were identified post-Hurricane Katrina, but only 83 patients completed the questionnaires and were analyzed. Clinical, demographic, and socioeconomic data were recorded. Chi-square test and t test were used for comparisons. Patients who felt that there was a lack of access to cancer care would have sought treatment earlier had they had better access to cancer care (chi-square[1] = 32; p Hurricane Katrina would have sought treatment earlier with better access to cancer care. These patients also reported difficulty obtaining cancer treatment. Availability of transportation affected access to cancer care in patients with early-stage cancers. Clinical, demographic, and socioeconomic factors did not influence access to cancer care. © 2010 Wiley Periodicals, Inc. Head Neck, 2011.

    The authors report a comparison of different techniques for an additional irradiation of the tumour bed, in terms of local control and aesthetic result in the case of a breast cancer. This additional irradiation has been delivered by electron beam in five fractions, high dose rate curie-therapy in two fractions, photon beam in five or six fractions, and low dose rate curie-therapy. The dose increase in the tumour bed allows the local control rate to be increased without compromising aesthetic results. However, the comparison of the different boost techniques does not reveal significant differences. Short communication

    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.

    2004-06-15

    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

    2011-12-01

    In 2002, International Agency for Research on Cancer launched a multicentric case-control study of head and neck cancer in 15 centres in 11 European countries, Croatia included. The Alcohol-related Cancers and Genetic Susceptibility in Europe (ARCAGE) study database with approximately 2500 case-control pairs is currently the largest head and neck cancer patients database in Europe. The aim of the present study was to estimate the risk of smoking and alcohol consumption in head and neck cancer patients from Zagreb region recruited in scope of the ARCAGE study. The cases (45 males, 9 females) and the controls (37 males, 9 females) were recruited from University Hospital Dubrava and Merkur University Hospital. A blood sample and a lifestyle questionnaire were collected from all study subjects. Data were analysed by logistic regression analysis. The distribution of cases was: 43 oral, 9 pharyngeal and 2 laryngeal cancer cases. Ever-smokers had a 4-fold higher cancer risk (adjusted OR 4.3 (CI 1.20-15.4)) compared to never-smokers. The adjusted odds ratio for alcohol consumption more than once a week was 4.1 (CI 1.5-11.2). The results are in keeping with previously published data from other countries.

    For patients with head and neck cancer (HNC), communication difficulties often create substantial barriers in daily life, affecting a person's ability to return to work, establish or maintain relationships, or participate in everyday activities. To examine variables significantly associated with communication in everyday activities, or communicative participation, in adult survivors of HNC. In a cross-sectional study, from November 1, 2008, through March 18, 2011, participants completed questionnaires about specific experiences and symptoms associated with their health and communication. Seventeen variables were considered in association with communicative participation. Data were collected from adult survivors of HNC residing in a community. Participants completed questionnaires, in English, either online or using paper forms according to their preference. Participants were recruited through support groups, professional email lists, and professional contacts. Communicative participation and predictor variables were measured using a variety of validated patient-report scales and demographic information. Multiple linear regression analysis was conducted with variables entered using a backward stepwise regression procedure. Variables with significant regression coefficients were retained in the model and reported as change in R2. One hundred ninety-seven adults (121 males and 76 females; mean age, 61.5 years) participated, all at least 6 months posttreatment of HNC with no additional medical conditions affecting speech. The final model contained 4 significant variables (R2 = 0.462): self-rated speech severity, cognitive function, laryngectomy status, and time since diagnosis. Better communicative participation was associated with less severe speech and cognitive problems; together, these 2 variables explained 42% of the variance in the model (self-rated speech severity, R2 = 0.227, and cognitive function, R2 = 0.193 [0.227 + 0.193 = 0.420 = 42

    This is the official guideline endorsed by the specialty associations involved in the care of head and neck cancer patients in the UK. The disease itself and the treatment can have far reaching effects on speech and swallow function, which are consistently prioritised by survivors as an area of concern. This paper provides recommendations on the assessments and interventions for speech and swallow rehabilitation in this patient group. Recommendations • All multidisciplinary teams should have rehabilitation patient pathways covering all stages of the patient's journey including multidisciplinary and pre-treatment clinics. (G) • Clinicians treating head and neck cancer patients should consult the National Cancer Rehabilitation Pathway for head and neck cancers. (G) • All head and neck cancer patients should have a pre-treatment assessment of speech and swallowing. (G) • A programme of prophylactic exercises and the teaching of swallowing manoeuvres can reduce impairments, maintain function and enable a speedier recovery. (R) • Continued speech and language therapist input is important in maintaining voice and safe and effective swallow function following head and neck cancer treatment. (R) • Disease recurrence must be ruled out in the management of stricture and/or stenosis. (R) • Continuous radial expansion balloons offer a safe, effective dilation method with advantages over gum elastic bougies. (R) • Site, length and completeness of strictures as well as whether they are in the presence of the larynx or not, need to be assessed when establishing the likelihood of surgically improved outcome. (G) • Primary surgical voice restoration should be offered to all patients undergoing laryngectomy. (R) • Attention to surgical detail and long-term speech and language therapist input is required to optimise speech and swallowing after laryngectomy. (G) • Patients should commence wearing heat and moisture exchange devices as soon as possible after

  16. Role of infectious agents in the carcinogenesis of brain and head and neck cancers

    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

    Background Lymphedema may disrupt local function and affect quality of life (QOL) in patients with head and neck cancer. The study aim was to examine the associations among severity of internal and external lymphedema, symptoms, functional status, and QOL in patients with head and neck cancer. Methods The sample included 103 patients who were ≥3 months post head and neck cancer treatment. Variables assessed included severity of internal and external lymphedema, physical/psychological symptoms, functional status, and QOL. Results Severity of internal and external lymphedema was associated with physical symptoms and psychological symptoms. Patients with more severe external lymphedema were more likely to have a decrease in neck left/right rotation. The combined effects of external and internal lymphedema severity were associated with hearing impairment and decreased QOL. Conclusions Lymphedema severity correlates with symptom burden, functional status, and QOL in patients post head and neck cancer treatment. PMID:22791550

    The purpose of this study was to objectively assess this widely recognised problem of the bulky adipocutaneous Anterolateral thigh flap in the European population that may have implications in the reconstruction of head and neck cancer patients. We report 50 cases that underwent specific prospective thigh skinfold thickness assessment as part of assessment of suitability for ALT flap reconstruction following cancer ablation. The null hypothesis was that thigh skinfold thickness and circumference in an oral cancer population do not differ significantly from published sino-Asian norms. This study confirms anthropometrically the suspicion that European thigh skinfold thickness in a head and neck cancer population is greater than sino-Asian comparators.

    Objective: To investigate the number and level of occult neck lymphatic metastasis for squamous cell carcinoma of tongue in clinical stage Ⅰ/Ⅱ, and the relationship between cell differentiation and occult neck lymphatic metastasis. Methods: A total of 101 cases diagnosed preoperatively as having squamous cell carcinoma of tongue in clinical stage Ⅰ/Ⅱ (cT1/T2N0M0) between January 2005 and April 2015 were analysed retrospectively. Whether presence of occult neck lymphatic metastasis in these cases was studied. Results: Occult neck lymphatic metastases were found in 22 (21.78%) of 101 cases, 10 men and 12 women, with an age range of 22 to 83 years. There was not statistically significant association between tumor size or cell differentiation and occult neck lymphatic metastasis (P>0.05). The metastasis occurred most commonly in level Ⅱ, followed by levelsⅠ, Ⅲ and Ⅳ. There was no lymph node metastasis in Level Ⅴ. There were total 20 cases with occult neck lymphatic metastasis in at least one of levelⅠ, Ⅱ, Ⅲ(90.9%), One of these case was skipping metastasis in level Ⅲ(4.6%). Conclusion: The early tongue cancer has a high rate of occult lymph metastasis, which occurs commonly in levels Ⅱ, Ⅰ and Ⅲ, but there is not significant association between the metastasis and tumor size or cell differentiation.

    Background The association between dietary patterns and head and neck cancer has rarely been addressed. Patients and methods We used individual-level pooled data from five case–control studies (2452 cases and 5013 controls) participating in the International Head and Neck Cancer Epidemiology consortium. A posteriori dietary patterns were identified through a principal component factor analysis carried out on 24 nutrients derived from study-specific food-frequency questionnaires. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were estimated using unconditional logistic regression models on quintiles of factor scores. Results We identified three major dietary patterns named ‘animal products and cereals’, ‘antioxidant vitamins and fiber’, and ‘fats’. The ‘antioxidant vitamins and fiber’ pattern was inversely related to oral and pharyngeal cancer (OR = 0.57, 95% CI 0.43–0.76 for the highest versus the lowest score quintile). The ‘animal products and cereals’ pattern was positively associated with laryngeal cancer (OR = 1.54, 95% CI 1.12–2.11), whereas the ‘fats’ pattern was inversely associated with oral and pharyngeal cancer (OR = 0.78, 95% CI 0.63–0.97) and positively associated with laryngeal cancer (OR = 1.69, 95% CI 1.22–2.34). Conclusions These findings suggest that diets rich in animal products, cereals, and fats are positively related to laryngeal cancer, and those rich in fruit and vegetables inversely related to oral and pharyngeal cancer.

    Tobacco exposure is a key risk factor for head and neck cancer, and continued smoking after diagnosis negatively affects outcomes. The present study examined tobacco smoking, nicotine dependence, alcohol use, and depression in survivors of head and neck cancer. Subjects at least 6 months post-initial diagnosis of head and neck cancer (N=694) drawn from three VA otolaryngology clinics (n=309, VA patients) and a university-based otolaryngology clinic (n=385, non-VA patients) were administered questionnaires and standardized rating instruments for nicotine and alcohol dependence and for depression. Additional clinical information was extracted from chart reviews. Despite high rates of prior smoking, less than one-quarter of all subjects continued to smoke. After controlling for significant confounding variables, we found that VA patients were more likely to be current smokers (OR=1.9, 95% CI=1.3-3.0), but current VA smokers did not differ significantly from non-VA smokers on the Fagerström Test for Nicotine Dependence criterion (p=.69). The VA patients were more likely to screen positive for problem drinking on the Alcohol Use Disorder Identification Test (OR=2.1, 95% CI=1.3-3.7). After adjusting for other variables, we found no statistical difference between the groups in depression scores on the Geriatric Depression Scale-Short Form. The study provides data on smoking, alcohol use, and depression in head and neck cancer survivors indicating that VA patients are at increased risk for continued smoking and problem drinking relative to non-VA patients. Head and neck cancer patients benefit from aggressive smoking cessation efforts by the VA, but many patients need specialized services that integrate smoking interventions with treatment of comorbid alcoholism.

    Postdischarge care fragmentation, readmission to a hospital other than the one performing the surgery, has not been described in head and neck cancer patients. We sought to determine the frequency, risk factors, and outcomes for head and neck cancer patients experiencing postdischarge care fragmentation. Retrospective cohort study. We analyzed patients in the 2008 to 2010 California State Inpatient Database with a 30-day unplanned readmission following head and neck cancer surgery. The frequency of postdischarge care fragmentation, patient- and hospital-level risk factors for care fragmentation, readmission diagnosis, and readmission outcomes were determined. Of 561 patients with a 30-day unplanned readmission, 210 (37.4%) were readmitted to a hospital other than the one performing the surgery. Surgical hospitalization length of stay ≥15 days (odds ratio [OR]: 1.87, 95% confidence interval [CI]: 1.13-3.10) and discharge to a care facility (OR: 2.85, 95% CI: 1.77-4.58) were associated with care fragmentation. Overall, 39.8% of unplanned 30-day readmissions (223/561) were treatment complications, and 30.9% of treatment complication readmissions (69/223) occurred at a nonindex hospital. Patients with postdischarge care fragmentation had a 2.1-fold increased risk of in-hospital mortality within 30 days of readmission compared to patients readmitted to the index hospital (95% CI: 1.04-4.26). Postdischarge care fragmentation following head an neck cancer surgery is common, as 37% of readmitted patients and 31% of patients readmitted with a treatment complication are readmitted to a hospital other than the surgical hospital. Head and neck cancer patients experiencing care fragmentation are at increased risk of in-hospital mortality within 30 days of readmission. 4.

    Background The magnitude of risk conferred by the interaction between tobacco and alcohol use on the risk of head and neck cancers is not clear, since studies have used various methods to quantify the excess head and neck cancer burden. Methods We analyzed individual-level pooled data from 17 European and American case-control studies (11,221 cases and 16,168 controls) participating in the International Head and Neck Cancer Epidemiology (INHANCE) consortium. We estimated the multiplicative interaction parameter (ψ) and population attributable risks (PAR). Results A greater than multiplicative joint effect between ever tobacco and alcohol use was observed for head and neck cancer risk (ψ=2.15, 95%CI=1.53–3.04). The PAR for tobacco or alcohol was 72% (95%CI=61%–79%) for head and neck cancer, of which 4% was due to alcohol alone, 33% was due tobacco alone and 35% was due to tobacco and alcohol combined. The total PAR differed by subsite (64% for oral cavity cancer, 72% for pharyngeal cancer, 89% for laryngeal cancer), by sex (74% for men, 57% for women) by age (33% for cases 60 years) and by region (84% in Europe, 51% in North America, 83% in Latin America). Conclusions Our results confirm that the joint effect between tobacco and alcohol use is greater than multiplicative on head and neck cancer risk. However, a substantial proportion of head and neck cancers cannot be attributed to tobacco or alcohol use, particularly for oral cavity cancer, for head and neck cancer among women and among young onset cases.

    Full Text Available Abstract Background and purpose 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. Patients and nethods 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. 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. Laryngeal cancer patients had fewer complaints but benefited equally compared to oropharyngeal cancer patients from IMRT.

    Evidence of associations between single nutrients and head and neck cancer (HNC) is still more limited and less consistent than that for fruit and vegetables. However, clarification of the protective mechanisms of fruit and vegetables is important to our understanding of HNC etiology. We investigated the association between vitamin C intake from natural sources and cancer of the oral cavity/pharynx and larynx using individual-level pooled data from ten case-control studies (5959 cases and 12248 controls) participating in the International Head and Neck Cancer Epidemiology (INHANCE) consortium. After harmonization of study-specific exposure information via the residual method, adjusted odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were estimated using unconditional multiple logistic regression models on quintile categories of ’non-alcohol energy-adjusted’ vitamin C intake. In the presence of heterogeneity of the estimated ORs among studies, we derived those estimates from generalized linear mixed models. Higher intakes of vitamin C were inversely related to oral and pharyngeal (OR=0.54, 95% CI: 0.45–0.65, for the fifth quintile category versus the first one, p for trend<0.001) and laryngeal cancers (OR=0.52, 95% CI: 0.40–0.68, p for trend=0.006), although in the presence of heterogeneity among studies for both sites. Inverse associations were consistently observed for the anatomical subsites of oral and pharyngeal cancer, and across strata of age, sex, education, body mass index, tobacco, and alcohol, for both cancer sites. The inverse association of vitamin C intake from foods with HNC may reflect a protective effect on these cancers; however, we cannot rule out other explanations. PMID:25627906

    The safety and success of microvascular transfer have been well documented in the general population, but the good results achieved with the use of free flaps in elderly patients have received little attention. This study sought to identify differences in complications, morbidity and functional outcomes between elderly (≥ 75 years) and younger (patients treated surgically for advanced head and neck cancer using the Head and Neck 35 module of the European Organisation for Research and Treatment of Cancer quality of life questionnaire. Patient treatment consisted of composite resection, including excision of the primary tumour with ipsilateral or bilateral neck dissection and microvascular reconstruction. Eighty-five microvascular tissue transfers were performed to reconstruct major surgical defects. Postoperative radiation therapy was performed when indicated. Total flap loss occurred in three cases in elderly patients and two cases in younger patients. The rates of major surgical complication were 9% in young patients and 11% in elderly patients. No significant difference was observed between the two groups in the rates of major and minor flap complications, morbidity or long-term functional outcome. The results of the present analysis indicate that free-flap microvascular reconstruction can be considered a safe procedure in elderly patients with head and neck cancer.

    In recent years, our knowledge and understanding of head and neck squamous cell carcinoma (HNSCC) has expanded dramatically. New high-throughput sequencing technologies have accelerated these discoveries since the first reports of whole-exome sequencing of HNSCC tumors in 2011. In addition, the discovery of human papillomavirus in relationship with oropharyngeal squamous cell carcinoma has shifted our molecular understanding of the disease. New investigation into the role of immune evasion in HNSCC has also led to potential novel therapies based on immune-specific systemic therapies.

    Purpose This study examined the psychosocial adjustment and needs of family caregivers of head and neck cancer survivors at 6–24 months post-treatment. Methods Family caregivers of head and neck cancer survivors (N = 89) completed mailed questionnaires that assessed demographic variables, mental health, quality of life, and practical and informational needs. Results Thirty-eight percent of caregivers reported moderate to high distress. However, quality of life scores for the entire sample (N = 89) were better than the scores reported in initial validation studies on caregivers of patients undergoing active cancer treatment. Greater time spent caregiving was associated with worse psychological well-being, but also more positive adaptation to caregiving. In addition, 39% of caregivers reported that all of their practical and informational needs were being met. Conclusions Findings suggest that research and clinical efforts are needed to address the psychosocial concerns of this population. PMID:19390870

    Full Text Available Abstract Background and aims To report our experience and review the literature of thyroid cancer obstructing the great veins in the neck, highlighting clinical aspects and response to treatment. Methods Clinical data were collected from the thyroid cancer register and from follow-up clinic visits of patients referred to the Thyroid Unit at the Royal Marsden Hospital. A Medline literature search was conducted between 1980 and 2007. Results Of 1448 patients with thyroid cancer on our cancer register and treated in our unit over the last 60 years, we identified five patients, four women and one man, aged 43 – 81 years with a median follow up of 28 (24–78 months in whom tumour had occluded the great veins in the neck. All patients underwent total thyroidectomy and all subsequently received ablative 131I with the exception of patient 3 whose post-operative isotope scan shown no significant 131I uptake. External beam radiotherapy to the neck and upper mediastinum was used for residual disease control in the 5 patients. The median survival was 28 months and the disease-free survival was 24 months. One patient remains asymptomatic but with disease 53 months after initial presentation. Survival in this small series is significantly better than that previously reported for this condition. Conclusion A multimodality therapeutic approach comprising surgery, radioiodine and external beam radiotherapy may give the best results for patients in whom thyroid cancer is occluding the great veins.

    Summary Prophylactic central neck dissection in papillary thyroid cancer is controversial. In this retrospective cohort study, the aim was to assess possible advantages of prophylactic central neck dissection with total thyroidectomy in cN0 papillary thyroid cancer. A total of 244 consecutive patients with papillary thyroid cancer, without clinical and ultrasound nodal metastases (cN0), were evaluated out of 1373 patients operated for a thyroid disease at the Istituto Europeo di Oncologia, Milan, Italy from 1994 to 2006. Of these 244 patients, 126 (Group A) underwent thyroidectomy with central neck dissection, while 118 (Group B) underwent thyroidectomy alone. Demographic, clinical and pathological features were analysed. Overall recurrence rate was 6.3% (8/126) in Group A and 7.7% (9/118) in Group B, with a mean follow-up of 47 (Group A) and 64 (Group B) months. In Group A patients, 47% were pN1a and all patients with recurrence had nodal involvement (p = 0.002). Survival rate did not differ in the two groups. Nine patients were lost to follow-up. Group A patients were older and their tumours were larger in size; according to the pT distribution, a higher extra-capsular invasion rate was observed. The two groups were equivalent as far as concerns histological high risk variants and multifocality. Nodal metastases correlated with stage: pT1-2 vs. pT3-T4a, p = 0.0036. A lower risk of nodal metastases was related to thyroiditis (p = 0.0034). In conclusion, central neck metastases were predictive of recurrence without influencing prognosis. From data obtained, possible greatest efficacy of central neck dissection in pT3-4 papillary thyroid cancer without thyroiditis is suggested. PMID:20111614

    Full Text Available BACKGROUND : The changes in lipid profile have long been associated with cancer because lipids play a key role in maintenance of cell integrity. AIMS : The present study evaluated alterations in plasma lipid profile in untreated head and neck cancer patients as well as patients with oral precancerous conditions (OPC and its association with habit of tobacco consumption. MATERIAL AND METHODS : This hospital-based case control study included 184 head and neck cancer patients, 153 patients with OPC and 52 controls. Plasma lipids including: (i Total cholesterol, (ii LDL cholesterol (LDLC, (iii HDL cholesterol (HDLC (iv VLDL cholesterol (VLDLC and (v triglycerides were analysed by spectrophotometric kits. STATISTICAL ANALYSIS USED : Student′s t-test was performed to compare mean values of the parameters. RESULTS : A significant decrease in plasma total cholesterol and HDLC was observed in cancer patients (P=0.008 and P=0.000 respectively as well as in patients with OPC (P=0.014 and P=0.000, respectively as compared to the controls. The plasma VLDL and triglycerides levels were significantly lower in cancer patients as compared to the patients with OPC (P=0.04 and controls (P=0.059. The tobacco habituates showed lower plasma lipid levels than the non-habituates. Our data strengthen the evidence of an inverse relationship between plasma lipid levels and head and neck malignancies as well as OPC. CONCLUSION :The lower levels of plasma cholesterol and other lipid constituents in patients might be due to their increased utilization by neoplastic cells for new membrane biogenesis. The findings strongly warrant an in-depth study of alterations in plasma lipid profile in head neck cancer patients.

  2. Image-guided radiotherapy for locally advanced head and neck cancer

    Directory of Open Access Journals (Sweden)

    Nam Phong Nguyen

    2013-07-01

    Full Text Available Treatment of locally advanced head and neck cancer remains a challenge because of the head and neck complex anatomy and the tumor invasion to the adjacent organs and/or metastases to the cervical nodes. Postoperative irradiation or concurrent chemoradiation may lead to damage of radiosensitive structures such as the salivary glands, mandible, cochlea, larynx, and pharyngeal muscles. Xerostomia, osteoradionecrosis, deafness, hoarseness of the voice, dysphagia, and aspiration remain serious complications of head and neck irradiation and impair patient quality of life. Intensity-modulated and image-guided radiotherapy by virtue of steep dose gradient and daily imaging may allow for decreased radiation of the organs at risk for complication while preserving loco-regional control.

    Evidence of associations between single nutrients and head and neck cancer (HNC) is still more limited and less consistent than that for fruit and vegetables. However, clarification of the protective mechanisms of fruit and vegetables is important to our understanding of HNC etiology. We investigated the association between vitamin C intake from natural sources and cancer of the oral cavity/pharynx and larynx using individual-level pooled data from ten case-control studies (5,959 cases and 12,248 controls) participating in the International Head and Neck Cancer Epidemiology (INHANCE) consortium. After harmonization of study-specific exposure information via the residual method, adjusted odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were estimated using unconditional multiple logistic regression models on quintile categories of 'non-alcohol energy-adjusted' vitamin C intake. In the presence of heterogeneity of the estimated ORs among studies, we derived those estimates from generalized linear mixed models. Higher intakes of vitamin C were inversely related to oral and pharyngeal (OR = 0.54, 95% CI: 0.45-0.65, for the fifth quintile category versus the first one, p for trendcancers (OR = 0.52, 95% CI: 0.40-0.68, p for trend = 0.006), although in the presence of heterogeneity among studies for both sites. Inverse associations were consistently observed for the anatomical subsites of oral and pharyngeal cancer, and across strata of age, sex, education, body mass index, tobacco, and alcohol, for both cancer sites. The inverse association of vitamin C intake from foods with HNC may reflect a protective effect on these cancers; however, we cannot rule out other explanations.

    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.

    Extracellular matrix degradation by matrix metalloproteinases (MMPs) plays a pivotal role in cancer progression by promoting motility, invasion and angiogenesis. Studies have shown that MMP expression is increased in head and neck squamous cell carcinomas (HNSCCs), one of the most common cancers in the world, and contributes to poor outcome. In this review, we examine the expression pattern of MMPs in HNSCC by microarray datasets and summarize the current knowledge of MMPs, specifically MMP-1, -3, -7 -10, -12, -13, 14 and -19, that are highly expressed in HNSCCs and involved cancer invasion and angiogenesis.

    Full Text Available The aim of the study was to investigate cancer stem signaling during the repopulation response of a head and neck squamous cell cancer (HNSCC xenograft after radiation treatment. Xenografts were generated from low passage HNSCC cells and were treated with either sham radiation or 15 Gy in one fraction. At different time points, days 0, 3, and 10 for controls and days 4, 7, 12, and 21, after irradiation, 3 tumors per group were harvested for global gene expression, pathway analysis, and immunohistochemical evaluation. 316 genes were identified that were associated with a series of stem cell-related genes and were differentially expressed (p≤0.01 and 1.5-fold at a minimum of one time point in UT-SCC-14 xenografts after radiation. The largest network of genes that showed significant changes after irradiation was associated with CD44, NOTCH1, and MET. c-MET and ALDH1A3 staining correlated with the changes in gene expression. A clear pattern emerged that was consistent with the growth inhibition data in that genes associated with stem cell pathways were most active at day 7 and day 12 after irradiation. The MET/CD44 axis seemed to be an important component of the repopulation response.

    The objective of present study was to classify oral mucositis according to the Common Toxicity Criterion (CTC) international parameters in head and neck tumor patients simultaneously treated with radio and chemotherapy, and characterize a patient profile in our area, observing the individuals' habits, tumor characteristics, treatment protocol and acute reaction intensity. Fifty patients undergoing simultaneous 66 to 70 Gy megavoltage radiotherapy and cisplatin/carboplatin chemotherapy were evaluated in this study. Weekly evaluations of the degree of mucositis were perfoemed according to CTC, a four-degree ordinal scale; 36% of all patients and 100% of those with diabetes discontinued treatment due to mucositis, showing that this pathology contributes to the severity of mucositis.

    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 (pinternet, 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.

    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.

    Receptors for interleukin-13 (IL-13R) are overexpressed on several types of solid cancers including gliobastoma, renal cell carcinoma, AIDS Kaposi's sarcoma, and head and neck cancer. Recombinant fusion proteins IL-13 cytotoxin (IL13-PE38QQR or IL13-PE38) have been developed to directly target IL-13R-expressing cancer cells. Although it has been found that IL-13 cytotoxin has a direct potent antitumor activity in vivo in nude mice models of human cancers, the involvement of indirect antitumor effecter molecules such as nitric oxide (NO) is unknown. To address this issue, we assessed the effect of NO inhibiter N(omega)-monomethyl-l-arginine on IL-13 cytotoxin-mediated cytotoxicity and NO2/NO3 production in HN12 head and neck cancer cells. In addition, antitumor effects and NO levels in HN12 and KCCT873 head and neck tumors xenografted s.c. in nude mice when treated with IL-13 cytotoxin were evaluated by tumor measurement, Western blot, and immunohistochemistry analyses. Pretreatment of animals with N(omega)-monomethyl-l-arginine significantly decreased the NO levels and IL-13 cytotoxin-mediated antitumor effects. In addition, depletion of macrophages, known to produce NO, also decreased antitumor activity of IL-13 cytotoxin. Based on these studies, we concluded that NO accelerates antitumor effect of IL-13 cytotoxin on head and neck tumor cells. Because IL-13 cytotoxin is currently being tested in the clinic for the treatment of patients with recurrent glioblastoma maltiforme, our current findings suggest maintaining macrophage and NO-producing cellular function for optimal therapeutic effect of this targeted agent.

    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.

    Full Text Available Lymph node metastasis (LNM in many solid cancers is a well-known prognostic factor; however, it has been debated whether regional LNM simply reflects tumor aggressiveness or is a source for further tumor dissemination. Similarly, the metastatic process in head and neck cancer (HNC has not been fully evaluated. Thus, we aimed to investigate the relative significance of LNM in metastatic cascade of HNC using functional imaging of HNC patients and molecular imaging in in vivo models. First, we analyzed 18Fluorodeoxyglucose positron emission tomography (PET parameters of 117 patients with oral cancer. The primary tumor and nodal PET parameters were measured separately, and survival analyses were conducted on the basis of clinical and PET variables to identify significant prognostic factors. In multivariate analyses, we found that only the metastatic node PET values were significant. Next, we compared the relative frequency of lung metastasis in primary ear tumors versus lymph node (LN tumors, and we tested the rate of lung metastasis in another animal model, in which each animal had both primary and LN tumors that were expressing different colors. As a result, LN tumors showed higher frequencies of lung metastasis compared to orthotopic primary tumors. In color-matched comparisons, the relative contribution to lung metastasis was higher in LN tumors than in primary tumors, although both primary and LN tumors caused lung metastases. In summary, tumors growing in the LN microenvironment spread to systemic sites more commonly than primary tumors in HNC, suggesting that the adequate management of LNM can reduce further systemic metastasis.

    Pain in head and neck cancer represents a major issue, before, during and after the oncological treatments. The most frequent cause of pain is chemo/radiation related oral mucositis, which involves 80% of the patients and worsens their quality of life inhibiting speaking, eating, drinking or swallowing and sometimes reducing the treatment compliance, the maximum dose intensity and thus the potential efficacy of treatment. Nevertheless pain is still often under estimated and undertreated. An Italian multidisciplinary group of head and neck cancer specialists met with the aim of reaching a consensus on pain management in this setting. The Delphi Appropriateness method was used for the consensus. External expert reviewers evaluated the final statements. The paper contains 30 consensus-reached statements about pain management in HNC patients and offers a review of recent literature in these topics.

    Twenty-nine patients with locally advanced head and neck cancer were treated with twice-a-day fractionated radiotherapy (TDFR) for a total dose of 72 Gy to 82 Gy combined with Neo-adjuvant chemotherapy (NAC) of CDDP+5FU and concurrent chemotherapy of low dose CBDCA between 1994 and 1997. Twenty-one cases (72%) had complete response and sixteen cases recurred. The relapse-free rate at 2 years was 23.4% and the actual 2-year survival rate was 42.0%. No severe toxicity has been observed. Based on this investigation, it was concluded that TDFR with chemotherapy is a promising modality for locally advanced head and neck cancer and toxicity is acceptable. (author)

    2011-08-15

    There is a strong rationale for potential benefits from proton therapy (PT) for selected cancers of the head and neck because of the opportunity to improve the therapeutic ratio by improving radiation dose distributions and because of the significant differences in radiation dose distribution achievable with x-ray-based radiation therapy (RT) and PT. Comparisons of dose distributions between x-ray-based and PT plans in selected cases show specific benefits in dose distribution likely to translate into improved clinical outcomes. However, the use of PT in head and neck cancers requires special considerations in the simulation and treatment planning process, and currently available PT technology may not permit realization of the maximum potential benefits of PT. To date, few clinical data are available, but early clinical experiences in sinonasal tumors in particular suggest significant improvements in both disease control and radiation-related toxicity

    To evaluate a single-institutional experience with the use of re-irradiation for recurrent and new primary cancers of the head and neck. The medical charts of 80 consecutive patients who underwent re-irradiation for local-regionally recurrent or second primary head and neck cancer between November 1998 and December 2015 were analyzed. Multivariate analysis was performed using Cox proportional hazard and logistic regression to determine predictors of clinical outcomes. Seventy-six of the 80 patients were evaluable. The median age was 57.5 (range 26.6-84.9); Intensity-modulated radiotherapy (IMRT) was used in 71 (93.4%) patients with a median dose of 60Gy. Thirty-one patients (40.8%) underwent salvage surgery before re-irradiation and 47 (61.8%) received concurrent systemic therapy. The median time interval between radiation courses was 25.3months (range 2-322months). The 2-year estimates of overall survival, progression free survival, locoregional control, and distant control were 51.0%, 31.3%, 36.8% and 68.3%, respectively. Patients who underwent salvage surgery prior to re-irradiation had significantly improved locoregional control, progression free survival, and overall survival (p<0.05, for all). On multivariate analysis, gross tumor volume (GTV) at re-irradiation and interval between radiation courses were associated with improved overall survival. Severe (grade⩾3) late complications were observed in 25 patients (32.8%). Re-irradiation for recurrent or second primary head and neck cancer is feasible and effective in select patients with head and neck cancer. The high observed rate of treatment-related morbidity highlights the continue challenges that accompany this approach. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Head and neck squamous cell cancer (HNSCC) is the 7th most common cancer worldwide. Despite the development of new therapeutic agents such as monoclonal antibodies, prognosis did not change for the last decades. Cold atmospheric plasma (CAP) presents the most promising new technology in cancer treatment. In this study the efficacy of a surface micro discharging (SMD) plasma device against two head and neck cancer cell lines was proved. Effects on the cell viability, DNA fragmentation and apoptosis induction were evaluated with the MTT assay, alkaline microgel electrophoresis (comet assay) and Annexin-V/PI staining. MTT assay revealed that the CAP treatment markedly decreases the cell viability for all tested treatment times (30, 60, 90, 120 and 180 s). IC 50 was reached within maximal 120 seconds of CAP treatment. Comet assay analysis showed a dose dependent high DNA fragmentation being one of the key players in anti-cancer activity of CAP. Annexin-V/PI staining revealed induction of apoptosis in CAP treated HNSCC cell lines but no significant dose dependency was seen. Thus, we confirmed that SMD Plasma technology is definitely a promising new approach on cancer treatment.

    NOTCH1 mutations have been reported to occur in 10% to 15% of head and neck squamous cell carcinomas (HNSCC). To determine the significance of these mutations, we embarked upon a comprehensive study of NOTCH signaling in a cohort of 44 HNSCC tumors and 25 normal mucosal samples through a set of expression, copy number, methylation, and mutation analyses. Copy number increases were identified in NOTCH pathway genes, including the NOTCH ligand JAG1. Gene set analysis defined a differential expression of the NOTCH signaling pathway in HNSCC relative to normal tissues. Analysis of individual pathway-related genes revealed overexpression of ligands JAG1 and JAG2 and receptor NOTCH3. In 32% of the HNSCC examined, activation of the downstream NOTCH effectors HES1/HEY1 was documented. Notably, exomic sequencing identified 5 novel inactivating NOTCH1 mutations in 4 of the 37 tumors analyzed, with none of these tumors exhibiting HES1/HEY1 overexpression. Our results revealed a bimodal pattern of NOTCH pathway alterations in HNSCC, with a smaller subset exhibiting inactivating NOTCH1 receptor mutations but a larger subset exhibiting other NOTCH1 pathway alterations, including increases in expression or gene copy number of the receptor or ligands as well as downstream pathway activation. Our results imply that therapies that target the NOTCH pathway may be more widely suitable for HNSCC treatment than appreciated currently.

    The aims of this study were to investigate the following in patients with head and neck cancer (HNC): (1) factors related to trismus that predict the development of trismus, (2) factors affecting quality of life and measurements of these factors, and (3) comparison of these findings in patients with and without trismus to evaluate the effects of trismus on quality of life. This cross-sectional study included the questionnaires: the Hospital Anxiety and Depression Scale (HADS) - Depression Subscale, the Chewing Function Questionnaire (CFQ), and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Head and Neck Cancer Module (EORTC QLQ-HN35). A scaled ruler was used to measure maximal intercisal opening (MIO). Of the 104 patients in the study, 8.7% had clinical depression. The average MIO was 35.81 mm, and 47.1% of patients had trismus. Moderate levels of chewing dysfunction with regard to different types of food were noted. Lower body mass index, chemoradiotherapy treatment, longer time since treatment completion, and higher radiation dose were significantly associated with trismus. Such patients had significantly lower head and neck-specific quality of life in terms of social contact, sexuality, teeth, mouth opening, dry mouth, feeling ill, nutritional supplement, and weight loss. Patients with trismus should be provided mouth opening exercises after treatment and programs to improve trismus and quality of life. Copyright © 2015 Elsevier Inc. All rights reserved.

    To improve the local control rate and the prognosis of locally unresectable head and neck cancer patients, we studied the concurrent chemoradiotherapy. Between September 1996 and September 2000, thirty-eight patients with locally unresectable head and neck cancer were administered concurrent chemoradiotherapy consisting of low-dose and long-term treatment with cisplatin (CDDP) plus 5-fluorouracil (5FU), or (L-CF); the L-CF regimen consisted of CDDP, 3 mg/m{sup 2} on 5 days of the week and 5FU, 150 mg/m{sup 2} as a 24-hour infusion on 5 days of the week. Concurrently, conventional radiotherapy was given up to total dose of around 60 Gy. In the 36 patients evaluable for response, 19 complete and 10 partial responses were noted, with an overall response rate of 81%. Oral mucositis and myelosuppression were the major side effects and dose limiting toxicity. This study demonstrates increase in survival among the responders (complete+partial) in the concurrent chemoradiotherapy setting. We concluded that this treatment strategy was beneficial. Further studies for patients with locally unresectable head and neck cancer are warranted. (author)

    Pain is common in head and neck cancer patients. Regardless of the cause, pain management is essential in supportive care. Recent research has suggested that opioid receptors on peripheral nerve terminals may play an important role in pain modulation. A number of publications have reported the use of topical morphine for painful ulcers that occur because of a variety of medical conditions. To the best of our knowledge, there are no reports in the literature regarding the use of morphine gel in head and neck cancer patients. We present two cases treated with morphine gel therapy for cutaneous pain resulting from radiation-induced dermatitis and tumor infiltration. We obtained good pain control in both cases without side effects. In one case, the use of the gel allowed a decrease in systemic opioid medication, and adverse effects of systemic opioid administration were resolved. Our experience suggests that this treatment presents great potential for selected head and neck cancer patients, especially those with prominent pain limited to the body surface.

    Given the dramatic changes in global head and neck cancer epidemiology, the purpose of this study was to present the findings of our investigation on patterns of head and neck cancer incidence/survival within the province of Ontario, Canada. Temporal variations in age/sex adjusted incidence and survival were analyzed for all incident head and neck cancer cases (n = 20 781) managed within Ontario from 1993-2010. From 1993-2010, the incidence of oropharyngeal (average annual percentage change [AAPC] 4.56%; P < .001) and salivary gland (AAPC 4.99%; P < .001) carcinomas increased, whereas oral cavity (AAPC -1.44%; P < .001) and laryngeal/hypopharyngeal (AAPC -3.20%; P < .001) carcinomas declined, and nasopharyngeal carcinoma (NPC) remained static (AAPC 0.28%; P = .72). A general trend for improved 5-year overall survival (OS), was observed for all tumor sites. Consistent with previous studies, our results suggest a simultaneous decline in tobacco-associated and increase in human papillomavirus (HPV)-mediated carcinomas. The rising incidence of salivary malignancy and improvement in 5-year OS are novel findings, in need of future investigation. © 2017 Wiley Periodicals, Inc.

    This study aimed to determine the type, accuracy and content of information available on the internet regarding head and neck cancer. The search engine Google was used to generate a list of the top 100 websites about head and neck cancer. The websites were evaluated using the DISCERN instrument and the JAMA benchmarks and whether the site displayed the Health on the Net seal was also recorded. The search yielded 1,650,000 sites on the Google website. Of the top 100 sites, a total of 33 sites were suitable for analysis due to duplicate links, non-functioning links and irrelevant website. 45% achieved all four JAMA benchmarks and 18% achieved only 1 benchmark. No website receiving the maximum mark on the overall score and four websites received the lowest overall score regarding the DISCERN instrument. The question with the poorest response score was \\'Does it describe how the treatment choices affect overall quality of life?\\' 39% of the websites displayed the Health on the Net (HON) seal. A wide variety of types of information are available on the internet regarding head and neck cancer with variable accuracy levels based on both Journal of the American Medical Association (JAMA) benchmarks and DISCERN. The onus lies with the practitioner to guide the patient regarding scientific reliability of information and to direct the patient in filtering the information sourced. The inclusion of quality of life related information is currently lacking and should be addressed to ensure a more comprehensive understanding for patients of treatment options.

    To update the outcomes of an institutional clinical management approach using ipsilateral neck radiotherapy in the treatment of node-positive squamous cell carcinoma of the tonsil with a well-lateralized primary lesion. Between August 2003 and April 2014, 61 consecutive patients with ipsilateral node-positive squamous cell carcinoma of the tonsil without involvement of the base of the tongue or midline soft palate were treated at a community hospital-based cancer center with radiotherapy to the primary site and ipsilateral neck. Overall survival, disease-free survival and freedom from contralateral failure were calculated. Median follow up was 37.2months (range 4-121months). Freedom from contralateral nodal failure at 5years was 98% with one contralateral nodal failure noted. The patient underwent a salvage neck dissection and was treated with post-operative radiotherapy with no evidence of disease to date. 5-year overall survival (OS) was 92.4% and 5year disease-free survival (DFS) was 86.7%. This represents the single largest series reported from a community hospital-based cancer center in which lateralized tonsil cancers with N+ disease were treated with ipsilateral neck radiotherapy. In this carefully selected cohort of patients with well-lateralized tonsil cancers, the risk of contralateral nodal failure appears to be <5%, suggesting that prophylactic radiation of the contralateral neck may not be necessary. Future planned studies will focus on prospectively selecting subgroups of patients eligible for treatment de-intensification as survivorship issues in excellent prognosis HPV positive patients are increasingly becoming relevant.

    The aim of this study was to determine how patients with head and neck cancer experience changes within their intimate relationships at the end of treatment and detect detrimental and facilitating factors in the process of resuming intimate relationships. Interviews were conducted with 131 patients. A core category - "being open versus not sharing the cancer journey" - emerged from the patients' narratives and was based on the experiences of engagement/disengagement, openness/fear, and patronizing attitudes/sharing the burden. The findings point to the necessity of patients being open about the disease trajectory and might be understood in the light of theories about potential changes in identity and self-concept.

    The management of patients with cervical lymph node metastases from an unknown primary cancer (CUP) remains a matter of controversy. Although new advanced diagnostic tools, such as positron emission tomography, have recently been introduced in oncology, the frequency of this tumour entity in clinical practice means it is still relevant. Recently introduced molecular profiling platforms may provide biological classification for the primary tissue of origin as well as insights into the pathophysiology of this clinical entity, including the characterisation of the Epstein-Barr virus and human papilloma virus genomas in the metastatic cervical nodes. Due to the lack of randomised trials, a standard therapy has not been identified yet. Although neck dissection followed by post-operative radiotherapy is the most generally accepted approach, there are other curative options that can be used in some patients: neck dissection alone, nodal excision followed by post-operative radiotherapy or radiotherapy alone. A major controversy remains in the target radiation volumes that range from ipsilateral neck irradiation to prophylactic irradiation of all potential mucosal sites and both sides of the neck. Finally, the administration of concurrent chemotherapy is currently being advised for patients with adverse prognostic factors.

    2012-05-01

    We assessed the sensitivity of positron emission tomography (PET) for detecting synchronous multiple primary cancers, particularly synchronous esophageal cancers in head and neck cancer patients. We retrospectively reviewed 230 head and neck cancer patients. All the patients routinely underwent the following examinations: urinalysis, occult blood, tumor marker detection [squamous cell carcinoma (SCC), cytokeratin fragment (CYFRA), and carcinoembryonic antigen (CEA)], esophagogastroduodenoscopy, colonoscopy (when CEA was high or occult blood was positive), abdominal ultrasonography, plain chest computed tomography (CT), and PET. Bronchoscopy was performed when CT revealed lung shadow of central region. Synchronous multiple primary cancers were detected in 42 (18.2%) patients. The diagnostic sensitivity of PET for synchronous primary cancers was as follows: esophagus, 7.6% (1/13); stomach, 25.0% (2/8); lung, 66.7% (4/6); head and neck, 75.0% (3/4); colon, 0% (0/1); kidney, 0% (0/1); and subcutaneous, 100% (1/1). The sensitivity of PET for detecting synchronous esophageal cancers is low because these are early-stage cancers (almost stage 0-I). Therefore, it is necessary to perform esophagogastroduodenoscopy for detecting synchronous esophageal cancers. PET is an important additional tool for detecting synchronous multiple primary cancers because the diagnostic sensitivity of PET in synchronous head and neck cancer and lung cancer is high. But PET has the limitation of sensitivity for synchronous multiple primary cancers because the diagnostic sensitivity of PET in synchronous esophageal cancer is very low.

    The head and neck cancer in Michoacán, Mexico, ranks as the third most common cancer and accounts for 12% of deaths. The increase in malnutrition in a patient with this disease has been associated with increased mortality. We studied prospectively 30 patients of both sexes, aged 18 years with head and neck cancer in the Cancer Care Center of Michoacan. In the evaluation period since August 2010 to August 2011. Formats were used VGS-Oncology (Subjective Global Assessment), NRS 2002 (Nutritional risk screen) and Guss (Gugging Swallowing Screen), through which nutritional risk was determined, and established the swallowing capacity of the study population. In our study, 53.3% of the population had moderate malnutrition according to the VGS Oncology, 33% weight loss record. The NRS 2002 show that 43.3% is at risk of malnutrition. The degree of dysphagia is shown more often in older patients, cancer type and stage of illness. Nutritional risk scales relate directly proportional to tumor location and stage, as well, there are other different oncological factors involved in the patient's nutritional deterioration. Therefore it is of vital importance to have a nutritionist as part of the multidisciplinary team, to detect the nutritional risk and to be able to handle it in an opportune way.

    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.

  9. The Role of HPV in Head and Neck Cancer Stem Cell Formation and Tumorigenesis

    Directory of Open Access Journals (Sweden)

    Mark S. Swanson

    2016-02-01

    Full Text Available The cancer stem cell (CSC theory proposes that a minority of tumor cells are capable of self-replication and tumorigenesis. It is these minority of cells that are responsible for cancer metastasis and recurrence in head and neck squamous cell cancers (HNSCC. Human papilloma virus (HPV-related cancer of the oropharynx is becoming more prevalent, which makes understanding of the relationship between HPV and CSCs more important than ever. This relationship is critical because CSC behavior can be predicted based on cell surface markers, which makes them a suitable candidate for targeted therapy. New therapies are an exciting opportunity to advance past the stalled outcomes in HNSCC that have plagued patients and clinicians for several decades.

  10. Stress-triggered atavistic reprogramming (STAR) addiction: driving force behind head and neck cancer?

    2016-01-01

    Recent results of the Cancer Genome Atlas on head and neck squamous cell carcinoma (HNSCC) revealed that HNSCC lacked predominant gain-of-function mutations in oncogenes, whereas an essential role for epigenetics in oncogenesis has become apparent. In parallel, it has gained general acceptance that cancer is considered as complex adaptive system, which evolves responding environmental selective pressures. This somatic evolution appears to proceed concurrently with the acquisition of an atavistic pluripotent state (i.e., "stemness"), which is inducible by intrinsic epigenetic reprogramming program as demonstrated by induced pluripotent stem (iPS) cells. This Nobel prize-winning discovery has markedly accelerated and expanded cancer stem cell research from the point of epigenetic reprogramming. Taken together, we hypothesize that stress-triggered atavistic reprogramming (STAR) may be the major driving force of HNSCC evolution. In this perspective, we discuss the possible mechanisms of STAR in HNSCC, focusing on recent topics of epigenetic reprogramming in developmental and cancer cell biology.

    The use of induction chemotherapy (CT) is controversial. We compared the survival of head and neck cancer patients receiving docetaxel- or platinum-based induction CT before concomitant chemoradiotherapy (CCRT) with the survival of those receiving upfront CCRT alone. Data from the National Health Insurance and cancer registry databases in Taiwan were linked and analyzed. We enrolled patients who had head and neck cancer between January 1, 2002 and December 31, 2011. Follow-up was from the index date to December 31, 2013. We included head and neck patients diagnosed according to the International Classification of Diseases, Ninth Revision, Clinical Modification codes 140.0-148.9 who were aged >20 years, at American Joint Committee on Cancer clinical cancer stage III or IV, and receiving induction CT or platinum-based CCRT. The exclusion criteria were a cancer history before head and neck cancer diagnosis, distant metastasis, AJCC clinical cancer stage I or II, receipt of platinum and docetaxel before radiotherapy, an age induction CT for >8 weeks before RT, induction CT alone before RT, cetuximab use, adjuvant CT within 90 days after RT completion, an RT dose cancer surgery before RT, nasopharyngeal cancer, in situ carcinoma, sarcoma, and head and neck cancer recurrence. We enrolled 10,721 stage III-IV head and neck cancer patients, with a median follow-up of 4.18 years (interquartile range, 3.25 years). The CCRT (arm 1), docetaxel-based induction CT (arm 2), and platinum-based CCRT (arm 3; control arm) groups comprised 7968, 503, and 2232 patients, respectively. Arm 3 was used to investigate mortality risk after induction CT. After adjustment for age, sex, clinical stage, and comorbidities, the adjusted hazard ratios (aHRs) (95% confidence interval [CI]) for overall death were 1.37 (1.22-1.53) and 1.44 (1.36-1.52) in arms 2 and 3, respectively. In a disease-specific survival rate analysis, aHRs (95% CI) of head and neck cancer-related death were 1.29 (1

    Traditionally, prescription and treatment planning in intracavitary brachytherapy for cervix cancer have used either reference points (mainly points A and B) or reference isodoses (60 Gy according to ICRU recommendations) to report doses to the target volume. Doses to critical organs were reported at bladder and rectum ICRU points. This practice has been supported by a long-standing clinical experience that has yielded an acceptable therapeutic ratio. The recent development of imaging has contributed to the improvement in target and organs at risk knowledge. In 2005 and 2006, the European group of brachytherapy -European Society for therapeutic radiology and oncology (GEC-E.S.T.R.O.) recommendations publications on 3-D based image brachytherapy have defined the different volumes of interest. These recommendations have been validated with intercomparison delineation studies. With the concomitant development of remote after-loading projectors, provided with miniaturized sources, it is now possible to plan radiation doses by adjusting dwell positions and relative dwell time values. These procedures allow better coverage of the targets while sparing O.A.R.. The recent literature data evidence a significant improvement in local control with no increase in complications. Further studies are needed to better define the dose recommended in both tumour and organs at risk. This is one of the goals of the European study on MRI-guided brachytherapy in locally advanced cervical cancer (E.M.B.R.A.C.E.) protocol (meaning of acronym: an international study on MRI-guided brachytherapy in locally advanced cervical cancer).

    Full-Field OCT (FFOCT) produces optical slices of tissue using white light interferometry providing in-depth 2D images, with an isotropic resolution around 1 micrometer. These optical biopsy images are similar to those obtained with established histological procedures, but without tissue preparation and within few minutes. This technology could be useful when diagnosing a lesion or at the time of its surgical management. Here we evaluate the clinical value of FFOCT imaging in the management of patients with Head and Neck cancers by assessing the accuracy of the diagnosis done on FFOCT images from resected specimen. FFOCT images from Head and Neck samples were first compared to the gold standard (HES-conventional histology). An image atlas dedicated to the training of pathologists was built and diagnosis criteria were identified. Then, we performed a morphological correlative study: both healthy and cancerous samples from patients who undergo Head and Neck surgery of oral cavity, pharynx, and larynx were imaged. Images were interpreted in a random way by two pathologists and the FFOCT based diagnostics were compared with HES (gold standard) of the same samples. Here we present preliminary results showing that FFOCT provides a quick assessment of tissue architecture at microscopic level that could guide surgeons for tumor margin delineation during intraoperative procedure.

    Purpose. To analyze the patterns and associations of adjunctive service visits by head and neck cancer patients receiving primary, concurrent chemoradiation therapy. Methods. Retrospective chart review of patients receiving adjunctive support during a uniform chemoradiation regimen for stages III-IV head and neck squamous cell carcinoma. Univariate and multivariate models for each outcome were obtained from simple and multivariate linear regression analyses. Results. Fifty-two consecutive patients were assessed. Female gender, single marital status, and nonprivate insurance were factors associated with an increased number of social work visits. In a multivariate analysis, female gender and marital status were related to increased social work services. Female gender and stage IV disease were significant for increased nursing visits. In a multivariate analysis for nursing visits, living greater than 20 miles between home and hospital was a negative predictive factor. Conclusion. Treatment of advanced stage head and neck cancer with concurrent chemoradiation warrants a multidisciplinary approach. Female gender, single marital status, and stage IV disease were correlated with increased utilization of social work and nursing services. Distance over 20 miles from the center was a negative factor. This information may help guide the treatment team to allocate resources for the comprehensive care of patients. PMID:23118755

    Sulforaphane is a naturally occurring compound found in broccoli and other cruciferous vegetables. Recently it gained attention because of its antiproliferative properties in many cancer cell lines. The aim of this study was to investigate whether sulforaphane could act as a radiosensitizer in head and neck squamous cell carcinoma cell lines. Four head and neck squamous cell carcinoma cell lines (i.e., (HNSCC) SCC9, SCC25, CAL27, and FADU) were treated with sulforaphane and subsequently irradiated. Then proliferation and clonogenic assays were performed. Apoptosis was detected by flow cytometry. Possible regulation of Akt and Mcl-1 was investigated by western blotting. Sulforaphane and radiation in combination leads to stronger inhibition of cell proliferation and of clonogenic survival than each treatment method alone. Western blot analysis of Akt and Mcl-1 showed no changed expression. Sulforaphane is a promising agent in the treatment of head and neck cancer due to its antiproliferative and radio-sensitizing properties. A combination of sulforaphane and radiation decreases clonogenic survival. Apoptosis is not regulated through Akt or the Mcl-1 protein. (orig.)

    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.

  19. Proton Radiation Therapy for Head and Neck Cancer: A Review of the Clinical Experience to Date

    Proton beam radiation has been used for cancer treatment since the 1950s, but recent increasing interest in this form of therapy and the construction of hospital-based and clinic-based facilities for its delivery have greatly increased both the number of patients and the variety of tumors being treated with proton therapy. The mass of proton particles and their unique physical properties (ie, the Bragg peak) allow proton therapy to spare normal tissues distal to the tumor target from incidental irradiation. Initial observations show that proton therapy is particularly useful for treating tumors in challenging locations close to nontarget critical structures. Specifically, improvements in local control outcomes for patients with chordoma, chonodrosarcoma, and tumors in the sinonasal regions have been reported in series using proton. Improved local control and survival outcomes for patients with cancer of the head and neck region have also been seen with the advent of improvements in better imaging and multimodality therapy comprising surgery, radiation therapy, and chemotherapy. However, aggressive local therapy in the proximity of critical normal structures to tumors in the head and neck region may produce debilitating early and late toxic effects. Great interest has been expressed in evaluating whether proton therapy can improve outcomes, especially early and late toxicity, when used in the treatment of head and neck malignancies. This review summarizes the progress made to date in addressing this question.

    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.

    Patients undergoing radiotherapy for head and neck cancer are at increased risk of developing oral candidiasis. The objective of this study was to investigate the clinical Candida mucositis and interruptions in radiotherapy in patients suffering from head and neck cancer, receiving fluconazole in comparison with a control group without specific prophylaxis. Eighty consecutive patients were randomized in a prospective double-blind trial of prophylactic oral fluconazole or treatment with the same drug when mycotic infections appeared. Adult head and neck cancer patients who were undergoing treatment with radiotherapy and/or chemotherapy, radiotherapeutic coverage of the entire oropharynx and oral cavity at least 3 cm anterior to the retromolar trigone and receiving a total dose of more than 6000 cGy and Karnofsky Performance Status (KPS) >70 were included in the study. Group A received radiation therapy plus fluconazole (Fluzole 100 mg/day) starting from the sixth irradiation session throughout the treatment; 40 patients in group B received the same baseline treatment, but were given fluconazole only when mycotic infections appeared. We evaluated 37 patients in group A and the first 37 patients were evaluated in group B. Three of the patients in group A (8.1%) and 14 of the patients in group B (37.8%) demonstrated clinical candidasis. Radiotherapy was interrupted in all of these patients. The differences between the two groups were statistically significant with respect to clinical candidiasis (P=0.005). The median discontinuation time was 5 days (range, 3-7 days) in group A and 7 days (range, 4-10 days) in group B. The median dose resulting in clinical candidiasis was 3200 cGy (range, 2200-5800 cGy) in all groups. In the fluconazole group it was 4200 cGy and in the control group 2800 cGy. These results suggest that patients undergoing head and neck radiation therapy are at risk of developing candidiasis and that fluconazole may be used to reduce the frequency of

    The impact of ablative oral cancer surgery was studied, with particular reference to recurrence and nodal metastasis, to assess survival probability and prognostic indicators and to elucidate if ethnicity influences the survival of patients. Patients who underwent major ablative surgery of the head and neck region with neck dissection were identified and clinical records were assessed. Inclusion criteria were stage I-IV oral and oropharyngeal malignancies necessitating resection with or without radiotherapy from 2004 to 2009. All individuals had a pre-operative assessment prior to the surgery. The post operative assessment period ranged from 1 year to 5 years. Survival distributions were analyzed using Kaplan-Meier curves. 87 patients (males:38%; females:62%) were included in this study, with an age range of 21-85 years. Some 78% underwent neck dissections while 63% had surgery and radiotherapy. Nodal recurrence was detected in 5.7% while 20.5% had primary site recurrence within the study period. Kaplan-Meier survival analysis revealed that the median survival time was 57 months. One year overall survival (OS) rate was 72.7% and three year overall survival rate dropped to 61.5%. On OS analysis, the log-rank test showed a significant difference of survival between Malay and Chinese patients (Bonferroni correction p=0.033). Recurrence-free survival (RFS) analysis revealed that 25% of the patients have reached the event of recurrence at 46 months. One year RFS rate was 85.2% and the three year survival rate was 76.1%. In the RFS analysis, the log-rank test showed a significant difference in the event of recurrence and nodal metastasis (p<0.001). Conservative neck is effective, in conjunction with postoperative radiotherapy, for control of neck metastases. Ethnicity appears to influence the survival of the patients, but a prospective trial is required to validate this.

    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.

    Several epidemiological studies have shown a positive association between adult height and cancer incidence. The only study conducted among women on mouth and pharynx cancer risk, however, reported an inverse association. This study aims to investigate the association between height and the risk of head and neck cancer (HNC) within a large international consortium of HNC. We analyzed pooled individual-level data from 24 case-control studies participating in the International Head and Neck Cancer Epidemiology Consortium. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated separately for men and women for associations between height and HNC risk. Educational level, tobacco smoking, and alcohol consumption were included in all regression models. Stratified analyses by HNC subsites were performed. This project included 17,666 cases and 28,198 controls. We found an inverse association between height and HNC (adjusted OR per 10 cm height = 0.91, 95% CI 0.86-0.95 for men; adjusted OR = 0.86, 95% CI 0.79-0.93 for women). In men, the estimated OR did vary by educational level, smoking status, geographic area, and control source. No differences by subsites were detected. Adult height is inversely associated with HNC risk. As height can be considered a marker of childhood illness and low energy intake, the inverse association is consistent with prior studies showing that HNC occur more frequently among deprived individuals. Further studies designed to elucidate the mechanism of such association would be warranted.

Response options were complete (CR), partial (PR), and no (NR) response. Posttreatment biopsies were performed in all patients with persistent and recurrent visible lesions. Results Thirty patients were enrolled, and 26 were evaluable. Mean follow-up was 15 months (range, 7–52 months). Twenty-four patients had a CR, 1 had a PR, and 1 had NR. Three patients with oral dysplasia with an initial CR experienced recurrence in the treatment field. All the patients with NR, a PR, or recurrence after an initial CR underwent salvage treatment. Temporary morbidities included edema, pain, hoarseness, and skin phototoxicity. Conclusion Photodynamic therapy with porfimer sodium is an effective treatment alternative, with no permanent sequelae, for oral and laryngeal dysplasia and early carcinoma. PMID:19687399

  8. HPV in Head and Neck Cancer-30 Years of History.

    Science.gov (United States)

    Syrjänen, Stina; Rautava, Jaana; Syrjänen, Kari

    The interesting history of papillomavirus (PV) research has been reviewed before. The history of human papillomavirus (HPV) in head and neck region starts in 1901 when the contagious transmission of warty lesions into the mouth via oral sex was described, although the confirmation of their viral etiology had to wait until 1907. Ullman was the first to associate the human wart virus with laryngeal warts. Parsons and Kidd described the natural history of oral PV infections in rabbits already in 1942, but these findings were corroborated in humans only recently. Koilocytotic atypia described by Koss and Durfee in 1956 was recognized as a sign of HPV infection in cervical precancer lesions only in 1976-1977 (Meisels and Fortin; Purola and Savia). This prompted systematic surveys of head and neck lesions for the detection of koilocytosis since the late 1970s, and the authors of this communication were the first to propose the HPV involvement in a subgroup of head and neck cancers. Brandsma and Abramson demonstrated HPV16 DNA in tonsillar SCCs in 1989. Since the early 2000s, HPV research of head and neck squamous cell carcinomas (HNSCC) has made impressive progress, confirming that the specific anatomic site plays a key role in determining the susceptibility to HPV infection. The most likely cancer sites associated with HPV are the base of the tongue and palatine tonsils, followed by oral cavity, larynx, and sinonasal mucosa. There is substantial geographic variation in HPV association with HNSCC. Patients with HPV-associated HNSCC are younger, and survival is better than in the absence of HPV.

    To examine the influence of smoking on observer based morbidity scores and patient assessed health related quality of life after treatment for head and neck cancer. The results of EORTC C30 and H&N35 questionnaires and DAHANCA morbidity scores were studied according to smoking status in 114...... recurrence free head and neck cancer patients. In contrast to observer based toxicity scoring, smoking had a significantly negative influence on 20 of the 33 quality of life scales. Previous smokers had quality of life scores in between never smokers and continuous smokers. Smoking after treatment of head...... and neck cancer adversely influenced a wide range of quality of life endpoints. Quitters had better quality of life than patients who continued to smoke after treatment, suggesting that smoking cessation may improve quality of life in addition to reducing the risk of new cancer.

  14. Image-guided adaptive radiotherapy for prostate and head-and-neck cancers

    Science.gov (United States)

    O'Daniel, Jennifer C.

    In the current practice of radiation therapy, daily patient alignments have been based on external skin marks or on bone. However, internal organ variation (both motion and volumetric changes) between treatment fractions can displace the treatment target, causing target underdosage and normal tissue overdosage. In order to deliver the radiation treatment as planned, more accurate knowledge of the daily internal anatomy was needed. Additionally, treatments needed to adapt to these variations by either shifting the patient to account for the daily target position or by altering the treatment plan. In this dissertation, the question of whether inter-fractional variations in internal patient anatomy combined with external set-up uncertainties produced measurable differences between planned and delivered doses for prostate and head-and-neck cancer patients was investigated. Image-guided adaptive treatment strategies to improve tumor coverage and/or reduce normal tissue dose were examined. Treatment deliveries utilizing various alignment procedures for ten prostate cancer patients and eleven head-and-neck cancer patients, each of whom received multiple CT scans over the course of treatment, were simulated. The largest prostate dose losses between planning and delivery were correlated with anterior/posterior and superior/inferior prostate displacement. Daily bone alignment sufficiently maintained target coverage for 70% of patients, ultrasound for 90%, and CT for 100%. A no-action-level correction protocol, which corrected the daily bone alignment for the systematic internal displacement of the prostate based on a pre-determined number of CT image sets, successfully improved the prostate and seminal vesicle dosimetric coverage. Three CT image sets were sufficient to accurately correct the bone alignment scheme for the prostate internal systematic shifts. For head-and-neck cancer patient treatment, setup uncertainties and internal organ variations did not greatly affect

    The risk of surgical site infection (SSI) remains high after major reconstructive surgery of the head and neck. Clinical data regarding SSI in microsurgical tongue reconstruction are described at National Cancer Hospital in Japan, including discussions of unfavorable representative cases, the relationship between SSI and preoperative irradiation at Okayama University Hospital in Japan, and strategies for SSI control in head and neck reconstruction. Local complications are inevitable in patients undergoing reconstruction in the head and neck areas. The frequency of major complications can be decreased, and late postoperative complications can be prevented with the help of appropriate methods.

    Surgery for maxilofacial cancer is often radical and disfiguring, and therefore can have an influence on patient's interpersonal relationship and social activities. However, little is known about self-presentation of disfigured patients during rehabilitation. This is an inductive and qualitative study based on 26 extensive interviews. The results demonstrate that patients with disfigurement cope actively with problems in their interpersonal relationship and even go through the empowerment process. Self-presentation of the disfigured patients consisted of four dimensions: (1)self-evaluation: (2)judgment of others' reactions; (3)intention of personal relations and style of self-presentation; and (4) concrete self-presentation using six "strategies". Each of the dimensions 1-3 included several processes that were generally taken in sequence according to time after surgery, but also strongly influenced by behaviors of family members or medical staff. "Strategies" chosen in dimension 4 depending upon the situations in dimensions 1-3 corresponded to the five type of "self-presentation" reported by Goffman (1959), except for "letting others be used to the patients", which was one of the continuous efforts to overcome their chronic disfigurement. Importantly, the patients became confident by focusing upon their chronic disfigurement. Importantly, the patients became confident by focusing upon their healthy parts such as maxiofacial functions recovered to some degree, and this confidence led to the acceptance of disfigurement and further to the expansion of their social behaviors.

    Full Text Available Treatment of cancer is race against time! Following radical excision, breathing, speech, mastication and swallowing are hampered. Face is invariably involved. Beside functional normalcy, excellent cosmetic restoration is necessary for patient′s life quality. Primary wound healing, quick resumption of adequate oral intake, prompt initiation of chemo-radiotherapy has direct bearing on cure. Primary reconstruction with pedicle or free flap is the choice of treatment in most protocols. Composite defects are requiring bone, muscle and skin restrict choice of donor site and may have shortfalls in aesthetic and functional requirements. To improve further newer, and newer modalities are being developed and used to give best aesthetic and functions. Navigation, use of three-dimensional imaging, stereo lithic model and custom made implant for reconstruction are recommended as they promise improvement in aesthetics. Robotic surgeries allow access for resection of tumours and reconstruction with free flap in deep oropharynx obviating need of doing mandibulotomy. Researchers in stem cell and tissue engineering are looking forward to regenerating tissues and avoid the need of autologous tissue flaps. Desired tissue combination across counter may be available in the future. Excellent immunosuppressant drugs have made it possible to reconstruct composite facial anatomical units with allotransplant in a single surgery, along sensory and motor recovery! Mythological heterogenic head transplant like clone Ganesha, will be a reality in the near future!!

    E-cadherin expression in the head and neck epithelium is essential for the morphogenesis and homeostasis of epithelial tissues. The cadherin-mediated cell-cell contacts are required for the anchorage-dependent growth of epithelial cells. Further, survival and proliferation require physical tethering created by proper cell-cell adhesion. Otherwise, the squamous epithelial cells will undergo programmed cell death.

    The biology of head and neck squamous cell carcinomas (HNSCC) and other cancers have been related to cancer stem-like cells (CSC). Specific markers, which vary considerably depending on tumor type or tissue of origin, characterize CSC. CSC are cancer initiating, sustaining and mostly quiescent. Compared to bulk tumors, CSC are less sensitive to chemo- and radiotherapy and may have low immunogenicity. Therapeutic targeting of CSC may improve clinical outcome. HNSCC has two main etiologies: human papillomavirus, a virus infecting epithelial stem cells, and tobacco and alcohol abuse. Here, current knowledge of HNSCC-CSC biology is reviewed and parallels to CSC of other origin are drawn where necessary for a comprehensive picture.

    The quality of life of patients treated for head and neck cancers and their carers is part of the current concerns of health care teams. Assessment tools were created and helped to highlight the severe physical effects (pain, mucositis…) and chronic (mutilation, post-radiation complications…) related to the disease or to different treatments but also to consider the psychosocial impact of this disease. Improving the quality of life through a thoughtful and comprehensive support that must be associated with somatic care, mental health care, rehabilitation and inclusion of social difficulties and suffering relatives. Supportive care shall ensure a good quality of life for patients treated and their families but also reduce the physical effects associated with the disease and treatment. They rely on coordination of care including the cancer networks established in the cancer plan to ensure comprehensive and continuous care for these patients.

    Lugol's iodine dye indicates the presence of unsuspected early oesophageal cancers during endoscopy at which such cancers fail to show the characteristic black colour change. We evaluated Lugol's iodine dye-enhanced endoscopy in 17 patients with oesophageal cancer. In a further 37 patients with head and neck cancer we examined the use of Lugol's iodine since these patients have a 29% risk of synchronous oesophageal cancer. The oesophagus was sprayed with Lugol's iodine (1.5%) during endoscopy. Any areas not turning black were biopsied. In 13 patients with oesophageal cancer discrete areas beyond the macroscopically obvious primary tumour showed no change in colour. Biopsy revealed cancer in all cases. Six synchronous cancers were found in the head and neck group, one of which was identified only by the use of Lugol's iodine. Lugol's iodine augmented the information gained about the oesophageal mucosa during endoscopy. It revealed unsuspected cancer which altered the management of patients with primary oesophageal cancer as well as those with head and neck cancer. We recommend the routine use of Lugol's iodine-enhanced endoscopy for surveillance of all 'at risk' oesophageal cases.

    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

  4. Comparison of acute toxicities of two chemotherapy schedules for head and neck cancers

    Full Text Available Background: Chemo-radiotherapy has become the standard of care for loco-regionally advanced head and neck cancers. Platinum based regimens are the most effective. Although benefits are proven with chemo-radiation, acute toxicities are markedly increased. The dose and delivery schedules of Cisplatin have ranged from intermittent higher dose [100 mg/m2] every 3 weeks to low dose [6 mg/m2] daily administration. At present there is no data indicating which regimen is superior. Purpose: To compare acute toxicities of two chemotherapy schedules for head and neck cancers. Materials and Methods: A total of 83 head and neck cancer patients treated with two schedules of concurrent chemo RT were analyzed, retrospectively, for treatment toxicity. In group A [51 patients], chemotherapy [CT] was administered on week 1, 4 and 7 [cisplatin 100 mg/m2] over a period of 2-3 days. In group B [32 patients], CT was delivered weekly [cisplatin 40 mg/m2]. Radiotherapy dose was 7000 cGy in 35 fractions for definitive concurrent chemo-radiation and 6600 cGy in 33 fractions for adjuvant treatment. Results: Group B patients had increased grade III skin and hematological toxicity, where as patients in group A had more pharyngeal toxicity. Treatment interruptions and percentage of weight loss were higher in group B. Weekly CT schedule had higher rate of severe mucositis, which was statistically significant on both univariate [ P =0.005] and multivariate [ P =0.007] analysis. Conclusions: Three weekly CT is less toxic than weekly. Weekly CT can be made more acceptable by reducing the dose and using feeding tubes for nutrition.

    Head and neck cancer patients treated with high-dose cisplatin and radiotherapy will suffer from hearing deficits. The current low-dose regimen seldom causes hearing threshold decrease. Tinnitus in this patient population has not been investigated earlier. We aimed to evaluate the possible ototoxicity of low-dose (40 mg/m(2)) weekly administered cisplatin with concomitant radiotherapy. Twenty-two patients with locally advanced head and neck cancer were prospectively recruited to participate the study after treatment recommendation for chemoradiotherapy with low-dose cisplatin and intensity-modulated radiotherapy. They filled in a Tinnitus Handicap Inventory and undertook audiologic evaluations before and after treatment. Ototoxicity was determined by >10 dB threshold shift at frequencies 4 and 8 kHz or in pure tone average. A historical cohort of nine patients treated with high-dose (100 mg/m(2)) cisplatin and radiotherapy was used for comparison. After treatment, study patients demonstrated no significant changes in their hearing over frequencies 0.5-4 kHz, and the threshold shifts were minor at 4 and 8 kHz. More than 50 % of patients reported no tinnitus after treatment and the remainder only had slight to moderate tinnitus causing no interference with their daily activities. In contrast, five of the nine patients having received high-dose cisplatin reported disturbing tinnitus. Further, changes in pure tone averages were exhibited in three of these patients and six had significant threshold shifts at 4 and 8 kHz. Head and neck cancer patients treated with concomitant intensity-modulated radiotherapy and low-dose cisplatin seem to experience only minor audiological sequelae and therefore, these patients appear to require no routine audiological monitoring. Such evaluation could be performed only when needed.

    Purpose: To present a novel method of tumor radiosensitization through Hsp27 knockdown using locked nucleic acid (LNA) and to investigate the role of Hsp27 in DNA double strand break (DSB) repair. Methods and Materials: Clonogenic survival assays, immunoblotting, the proximity ligation assay, and γH2AX foci analysis were conducted in SQ20B and FaDu human head-and-neck cancer cell lines treated with Hsp27 LNA and Hsp27 short hairpin RNA (shRNA). Additionally, nude mice with FaDu flank tumors were treated with fractionated radiation therapy after pretreatment with Hsp27 LNA and monitored for tumor growth. Results: Hsp27 LNA and Hsp27 shRNA radiosensitized head-and-neck cancer cell lines in an Hsp27-dependent manner. Ataxia-Telangectasia Mutated-mediated DNA repair signaling was impaired in irradiated cells with Hsp27 knockdown. ATM kinase inhibition abrogated the radiosensitizing effect of Hsp27. Furthermore, Hsp27 LNA and shRNA both attenuated DNA repair kinetics after radiation, and Hsp27 was found to colocalize with ATM in both untreated and irradiated cells. Last, combined radiation and Hsp27 LNA treatment in tumor xenografts in nude mice suppressed tumor growth compared with either treatment alone. Conclusions: These results support a radiosensitizing property of Hsp27 LNA in vitro and in vivo, implicate Hsp27 in double strand break repair, and suggest that Hsp27 LNA might eventually serve as an effective clinical agent in the radiotherapy of head-and-neck cancer.

    Exosomes are nanometer-sized extracellular vesicles that are believed to function as intercellular communicators. Here, we report that exosomes are able to modify the radiation response of the head and neck cancer cell lines BHY and FaDu. Exosomes were isolated from the conditioned medium of irradiated as well as non-irradiated head and neck cancer cells by serial centrifugation. Quantification using NanoSight technology indicated an increased exosome release from irradiated compared to non-irradiated cells 24 hours after treatment. To test whether the released exosomes influence the radiation response of other cells the exosomes were transferred to non-irradiated and irradiated recipient cells. We found an enhanced uptake of exosomes isolated from both irradiated and non-irradiated cells by irradiated recipient cells compared to non-irradiated recipient cells. Functional analyses by exosome transfer indicated that all exosomes (from non-irradiated and irradiated donor cells) increase the proliferation of non-irradiated recipient cells and the survival of irradiated recipient cells. The survival-promoting effects are more pronounced when exosomes isolated from irradiated compared to non-irradiated donor cells are transferred. A possible mechanism for the increased survival after irradiation could be the increase in DNA double-strand break repair monitored at 6, 8 and 10 h after the transfer of exosomes isolated from irradiated cells. This is abrogated by the destabilization of the exosomes. Our results demonstrate that radiation influences both the abundance and action of exosomes on recipient cells. Exosomes transmit prosurvival effects by promoting the proliferation and radioresistance of head and neck cancer cells. Taken together, this study indicates a functional role of exosomes in the response of tumor cells to radiation exposure within a therapeutic dose range and encourages that exosomes are useful objects of study for a better understanding of tumor

    Head and neck squamous cell carcinoma (HNSCC) is a leading cause of cancer-related deaths, with increasingly more cases arising due to high-risk human papillomavirus (HPV) infection. Cisplatin-based chemoradiotherapy is a standard-of-care for locally advanced head and neck cancer but is frequently ineffective. Research into enhancing radiation responses as a means of improving treatment outcomes represents a high priority. Here, we evaluated a CHK1 inhibitor (CCT244747) as a radiosensitiser and investigated whether a mechanistically rational triple combination of radiation/paclitaxel/CHK1 inhibitor delivered according to an optimized schedule would provide added benefit. CCT244747 abrogated radiation-induced G2 arrest in the p53-deficient HNSCC cell lines, HN4 and HN5, causing cells to enter mitosis with unrepaired DNA damage. The addition of paclitaxel further increased cell kill and significantly reduced tumor growth in an HN5 xenograft model. Importantly, a lower dose of paclitaxel could be used when CCT244747 was included, therefore potentially limiting toxicity. Triple therapy reduced the expression of several markers of radioresistance. Moreover, the more radioresistant HN5 cell line exhibited greater radiation-mediated CHK1 activation and was more sensitive to triple therapy than HN4 cells. We analyzed CHK1 expression in a panel of head and neck tumors and observed that primary tumors from HPV(+) patients, who went on to recur postradiotherapy, exhibited significantly stronger expression of total, and activated CHK1. CHK1 may serve as a biomarker for identifying tumors likely to recur and, therefore, patients who may benefit from concomitant treatment with a CHK1 inhibitor and paclitaxel during radiotherapy. Clinical translation of this strategy is under development. Mol Cancer Ther; 15(9); 2042-54. ©2016 AACR.

    Full Text Available Despite the development of more advanced medical therapies, cancer management remains a problem. Head and neck squamous cell carcinoma (HNSCC is a particularly challenging malignancy and requires more effective treatment strategies and a reduction in the debilitating morbidities associated with the therapies. Phytochemicals have long been used in ancient systems of medicine, and non-toxic phytochemicals are being considered as new options for the effective management of cancer. Here, we discuss the growth inhibitory and anti-cell migratory actions of proanthocyanidins from grape seeds (GSPs, polyphenols in green tea and honokiol, derived from the Magnolia species. Studies of these phytochemicals using human HNSCC cell lines from different sub-sites have demonstrated significant protective effects against HNSCC in both in vitro and in vivo models. Treatment of human HNSCC cell lines with GSPs, (−-epigallocatechin-3-gallate (EGCG, a polyphenolic component of green tea or honokiol reduced cell viability and induced apoptosis. These effects have been associated with inhibitory effects of the phytochemicals on the epidermal growth factor receptor (EGFR, and cell cycle regulatory proteins, as well as other major tumor-associated pathways. Similarly, the cell migration capacity of HNSCC cell lines was inhibited. Thus, GSPs, honokiol and EGCG appear to be promising bioactive phytochemicals for the management of head and neck cancer.

    We would like to assess the evolution of chronic dysphagia (1 year or more) following treatment for head and neck cancer. Modified barium swallow (MBS) examinations were performed in cancer-free patients who complained of dysphagia following treatment for head and neck cancer. The severity of the dysphagia was graded on a scale of 1-7. Each patient had at least 2 MBS. Severity of dysphagia was compared between the first and last MBS study to determine whether the swallowing dysfunction had returned to normal. Patients with complaint of dysphagia and normal MBS also underwent a regular barium swallow to assess the structural integrity of the pharynx and esophagus. Between 1996 and 2001, 25 patients with dysphagia underwent repeat MBS following treatment. Swallowing dysfunction did not return to normal in the majority of the patients. At a median time of 26 months following treatment (range 15-82 months), only two patient (8%) had normalization of the swallowing. The severity of dysphagia decreased in eight patients (32%), remained unchanged in 12 patients (48%), and worsened in five patients (20%). Eight patients (32%) still had aspiration problems at 12-83 months following treatment. Six patients (24%) required dilation because of pharyngeal stenosis. Three patients who required dilation had improvement of the dysphagia severity. Chronic dysphagia is a relentless process possibly due to excessive scarring. Patients with chronic dysphagia are at risk of malnutrition, and aspiration. Management of chronic dysphagia requires a team approach with nutritional support, psychological counseling, dilation, and tube feedings when indicated.

  12. Nutritional Interventions in Head and Neck Cancer Patients Undergoing Chemoradiotherapy: A Narrative Review

    2015-01-01

    Full Text Available The present review aimed to define the role of nutritional interventions in the prevention and treatment of malnutrition in HNC patients undergoing CRT as well as their impact on CRT-related toxicity and survival. Head and neck cancer patients are frequently malnourished at the time of diagnosis and prior to the beginning of treatment. In addition, chemo-radiotherapy (CRT causes or exacerbates symptoms, such as alteration or loss of taste, mucositis, xerostomia, fatigue, nausea and vomiting, with consequent worsening of malnutrition. Nutritional counseling (NC and oral nutritional supplements (ONS should be used to increase dietary intake and to prevent therapy-associated weight loss and interruption of radiation therapy. If obstructing cancer and/or mucositis interfere with swallowing, enteral nutrition should be delivered by tube. However, it seems that there is not sufficient evidence to determine the optimal method of enteral feeding. Prophylactic feeding through nasogastric tube or percutaneous gastrostomy to prevent weight loss, reduce dehydration and hospitalizations, and avoid treatment breaks has become relatively common. Compared to reactive feeding (patients are supported with oral nutritional supplements and when it is impossible to maintain nutritional requirements enteral feeding via a NGT or PEG is started, prophylactic feeding does not offer advantages in terms of nutritional outcomes, interruptions of radiotherapy and survival. Overall, it seems that further adequate prospective, randomized studies are needed to define the better nutritional intervention in head and neck cancer patients undergoing chemoradiotherapy.

    Our aim was to establish the incidence of trismus over time, together with risk factors (including quality of life (QoL)) for the prediction of trismus after treatment in patients with cancer of the head and neck. It was a longitudinal study of 152 patients accepted for primary operation who attended the head and neck cancer clinic of a tertiary referral cancer centre in the United Kingdom. A total of 87 patients was studied prospectively. Our results showed that 41/87 (47%) of patients presented with trismus, 57/80 (71%) had postoperative trismus, and 41/52 (79%) had trismus 6 months after operation or radiotherapy (trismus defined as a maximum mouth opening of ≤ 35 mm). Men and those who drank a lot of alcohol were less likely to have trismus after treatment. QoL variables showed that pain, eating, chewing, taste, saliva, social functioning, social contact, and dry mouth were significantly more impaired in the trismus group than among those without trismus. Postoperative differences in QoL between the two groups highlighted problems with social function and role-playing, fatigue, activity, recreation, and overall reduction in QoL. Women, and those who do not drink alcohol, are at particularly high risk of developing trismus, and, to prevent it and treat it, patients may benefit from multidisciplinary management at an early stage during treatment.

    Previous studies suggest that productivity losses associated with head and neck cancer (HNC) are higher than in other cancers. These studies have only assessed a single aspect of productivity loss, such as temporary absenteeism or premature mortality, and have only used the Human Capital Approach (HCA). The Friction Cost Approach (FCA) is increasingly recommended, although has not previously been used to assess lost production from HNC. The aim of this study was to estimate the lost productivity associated with HNC due to different types of absenteeism and premature mortality, using both the HCA and FCA. Survey data on employment status were collected from 251 HNC survivors in Ireland and combined with population-level survival estimates and national wage data. The cost of temporary and permanent time off work, reduced working hours and premature mortality using both the HCA and FCA were calculated. Estimated total productivity losses per employed person of working age were EUR253,800 using HCA and EUR6800 using FCA. The main driver of HCA costs was premature mortality (38% of total) while for FCA it was temporary time off (73% of total). The productivity losses associated with head and neck cancer are substantial, and return to work assistance could form an important part of rehabilitation. Use of both the HCA and FCA approaches allowed different drivers of productivity losses to be identified, due to the different assumptions of the two methods. For future estimates of productivity losses, the use of both approaches may be pragmatic.

    The aim of this study was to determine whether PET scans after radiotherapy (RT), visually interpreted as equivocal regarding metabolic neck node response can be used to accurately categorize patients as responders or nonresponders using a Likert scale and/or maximum standardized uptake value (SUVmax). Other aims were to determine the performance of different methods for assessing post-RT PET scans (visual inspection, a Likert scale and SUVmax) and to establish whether any method is superior in predicting regional control (RC) and overall survival (OS). In 105 patients with neck node-positive head and neck cancer, the neck node response was evaluated by FDG PET/CT 6 weeks after RT. The scans were clinically assessed by visual inspection and, for the purposes of this analysis, re-evaluated using the Deauville criteria, a five-point Likert scale previously used in lymphoma studies. In addition, SUVmax was determined. All assessment methods were able to significantly predict RC but not OS. The methods were also able to significantly predict remission of tumour after completion of RT. Of the 105 PET scans, 19 were judged as equivocal on visual inspection. The Likert scale was preferable to SUVmax for grouping patients as responders or nonresponders. All methods (visual inspection, SUVmax and the Likert scale) identified responders and nonresponders and predicted RC. A Likert scale is a promising tool to reduce to a minimum the problem of PET scans judged as equivocal. Consensus regarding qualitative assessment would facilitate PET reporting in clinical practice.

    and purpose of the study: The frequency of lung nodules in the head and neck cancer population is unknown, currently the only guidance available recommends following local policy. The aim of this study was to determine the incidence of pulmonary nodules in our head and neck cancer group and interpret the recently updated British Thoracic Society (BTS) Lung Nodule Guidelines in a head and neck cancer setting. 100 patients were diagnosed with head and neck cancer between July 2013-March 2014, clinico-pathological, demographic and radiological data was extracted from the electronic records. Images with lung findings were re-reviewed by a single consultant radiologist for patients with lung pathology on the initial staging CT report. Twenty patients (20%) had discreet pulmonary findings on CT. Eleven (11%) had lung nodules, 6 (6%) had lesions suspicious for metastasis and 3 (3%) had co-incidental bronchogenic primary cancers. These patients were re-imaged between 6 and 18 months and in 1 patient the previously identified 7 mm nodule had progressed to 16 mm at 1 year. There was no set follow up imaging protocol used. The MDT in NHS Lothian has reviewed the BTS guidance and now has a local policy for the management of lung nodules in head and neck cancer patients. Lung Nodules in the head and neck cancer population are common >10%. Higher risk patients with larger nodules should be risk assessed with validated assessment tools. PET-CT has a place in the assessment of lung nodules when risk of malignancy is high.

    2015-01-01

    This study investigated the contribution of patient and caregiver illness perceptions to the quality of life of head and neck cancer (HNC) patients. Ninety-eight patients and their caregivers (n = 80) completed questionnaires at diagnosis. Caregivers' illness perceptions were significantly more negative than patients with respect to consequences, timeline, treatment, concern, and the emotional impact of HNC. The interaction between some patient and caregiver illness perceptions explained additional variance in patient quality of life, above and beyond patients' own illness perceptions. These findings suggest that caregivers should be included in psychological interventions to improve HNC patient quality of life.

    Facial nerve paralysis can occasionally result from the treatment of head and neck cancer. The treatment of paralysis is patient specific, and requires an assessment of the remaining nerve segments, musculature, functional deficits, anticipated recovery, and patient factors. When feasible, reinnervation of the remaining musculature can provide the most natural outcome. However, the complex and topographic nature of facial innervation often prevents complete and meaningful movement. In these instances, a wide variety of procedures can be used to combat the functional and cosmetic sequella of facial paralysis.

    The objective of this study was to evaluate the impact of matched CT and MRI information on target delineation in radiotherapy planning for head and neck tumors. MRI images of eight patients with head and neck cancer in supine position, not necessarily obtained in radiotherapy treatment position were matched to the CT scans made in radiotherapy position using automatic three-dimensional chamfer-matching of bony structures. Four independent observers delineated the Gross Tumor Volume (GTV) in CT scans and axial and sagittal MR scans. The GTV`s were compared, overlapping volumes and non-overlapping volumes between the different datasets and observers were determined. In all patients a good match of CT and MRI information was accomplished in the head region. The combined information provided a better visualisation of the GTV, oedema and normal tissues compared with CT or MRI alone. Determination of overlapping and non-overlapping volumes proved to be a valuable tool to measure uncertainties in the determination of the GTV. CT-MRI matching in patients with head and neck tumors is feasible and makes a more accurate irradiation with higher tumor doses and less normal tissue complications possible. Remaining uncertainties in the determination of the GTV can be quantified using the combined information of MRI and CT.

    Given the complexities of multimodality treatment for patients with head and neck cancer, the rationale for the use of multidisciplinary teams (MDTs) to define individual optimal treatment strategies on a per-patient basis is apparent. Increased use of guideline-directed approaches, reduced time to treatment and improved outcomes, which result from use of an MDT approach in head and neck cancer, have been documented. A discussion of these recent advances, as well as presentation of available country-specific guidance on the roles and responsibilities of team members, supports the creation of similar local-language recommendations for the treatment of patients with head and neck cancer. Finally, expert practical advice on the implementation of MDTs may enable the establishment of the MDT approach more universally around the world.

    Full Text Available E-cadherin expression in the head and neck epithelium is essential for the morphogenesis and homeostasis of epithelial tissues. The cadherin-mediated cell-cell contacts are required for the anchorage-dependent growth of epithelial cells. Further, survival and proliferation require physical tethering created by proper cell-cell adhesion. Otherwise, the squamous epithelial cells will undergo programmed cell death. Head and neck cancers can escape from anoikis and enter into the epithelial-mesenchymal transition stages via the modulation of E-cadherin expression with epigenetic mechanisms. At epigenetic level, gene expression control is not dependent on the DNA sequence. In the context of E-cadherin regulation in head and neck cancers, 2 major mechanisms including de novo promoter hypermethylation and microRNA dysregulation are most extensively studied. Both of them control E-cadherin expression at transcription level and subsequently hinder the overall E-cadherin protein level in the head and neck cancer cells. Increasing evidence suggested that microRNA mediated E-cadherin expression in the head and neck cancers by directly/indirectly targeting the transcription suppressors of E-cadherin, ZEB1 and ZEB2.

    Sex hormones may play an important role in the tumorigenic process of the head and neck. The aim of our work was to investigate whether the androgen receptor (AR) CAG repeat polymorphism is associated with an increased relative risk for head and neck cancer. Genomic DNA from 103 male patients with head and neck carcinomas and 100 male controls were analyzed for the AR CAG polymorphism by PCR amplification and direct sequencing or denaturing polyacrilamide gel electrophoresis. Logistic regression analysis showed a significant association between CAG repeat length and risk of head and neck cancer in individuals with more than 20 CAG repeats [OR=2.54 (95% CI, 1.3-4.8)]. For the group of individuals with oral and laryngeal cancer the estimated relative risk was increased to 2.79 (95% CI, 1.2-6.3) and 3.06 (95% CI, 1.0-9.6), respectively, in men with CAG repeat length >20. These results suggest, for the first time, that shorter AR CAG repeat alleles have a protective effect for head and neck cancer development.

    Multidisciplinary team (MDT) meetings have an important role in the management of head and neck cancer. Increasing incidence of the disease and a drive towards centralised meetings on large numbers of patients mean that effective discussions are pertinent. We aimed to evaluate new cases within a single high volume head and neck cancer MDT and to explore the relation between the time taken to discuss each case, the number of discussants, and type of case. A total of 105 patients with a new diagnosis of head and neck malignancy or complex benign tumour were discussed at 10 head and neck cancer MDT meetings. A single observer timed each discussion using a stopwatch, and recorded the number of discussants and the diagnosis and characteristics of each patient. Timings ranged from 15 to 480 s (8 min) with a mean of 119 s (2 min), and the duration of discussion correlated closely with the number of discussants (rs=0.63, pmultidisciplinary input. Further studies may highlight extended discussions on patients with head and neck cancer, which may prompt a review of protocols and current evidence.

    Optical probes to identify tumor margins in vivo would greatly reduce the time, effort and complexity in the surgical removal of malignant tissue in head and neck cancers. Current approaches involve visual microscopy of stained tissue samples to determine cancer margins, which results in the excision of excess of tissue to assure complete removal of the cancer. Such surgical procedures and follow-on chemotherapy can adversely affect the patient's recovery and subsequent quality of life. In order to reduce the complexity of the process and minimize adverse effects on the patient, we investigate ex vivo tissue samples (stained and unstained) using digital holographic microscopy in conjunction with spectroscopic analyses (reflectance and transmission spectroscopy) in order to determine label-free, optically identifiable characteristic features that may ultimately be used for in vivo processing of cancerous tissues. The tissue samples studied were squamous cell carcinomas and associated controls from patients of varying age, gender and race. Holographic microscopic imaging scans across both cancerous and non-cancerous tissue samples yielded amplitude and phase reconstructions that were correlated with spectral signatures. Though the holographic reconstructions and measured spectra indicate variations even among the same class of tissue, preliminary results indicate the existence of some discriminating features. Further analyses are presently underway to further this work and extract additional information from the imaging and spectral data that may prove useful for in vivo surgical identification.

    Determine the incremental costs associated with head and neck cancer (HNCa) and compare the costs with other common cancers. Cross-sectional analysis of a healthcare expenditure database. The Medical Expenditure Panel Survey is a national survey of US households. All cases of HNCa were extracted for 2006, 2008, and 2010. The incremental expenditures associated with HNCa were determined by comparing the healthcare expenditures of individuals with HNCa to the population without cancer, controlling for age, sex, education, insurance status, marital status, geographic region, and comorbidities. Healthcare expenditures for HNCa were then compared to individuals with lung cancer and colon cancer to determine relative healthcare expenditures. An estimated 264,713 patients (annualized) with HNCa were identified. The mean annual healthcare expenditures per individual for HNCa were $23,408 ± $3,397 versus $3,860 ± $52 for those without cancer. The mean adjusted incremental cost associated with HNCa was $15,852 ± $3,297 per individual (P incremental cost, there was an increased incremental outpatient services cost of $3,495 ± $1,044 (P = .001) and an increased incremental hospital inpatient cost of $6,783 ± $2,894 (P = .020) associated with HNCa. The annual healthcare expenditures per individual fell in between those for lung cancer ($25,267 ± $2,375, P = .607) and colon cancer ($16,975 ± $1,291, P = .055). Despite its lower relative incidence, HNCa is associated with a significant incremental increase in annual healthcare expenditures per individual, which is comparable to or higher than other common cancers. In aggregate, the estimated annual costs associated with HNCa are $4.20 billion. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    This paper aims at studying the influence of single-nucleotide polymorphisms (SNPs) on cancer risk, tumor recurrence, and survival in head and neck (H&N) cancer patients. A total of 45 SNPs in 41 genes were investigated. A total of 174 Caucasian H&N cancer patients and 245 healthy blood donors were enrolled in the study. Ten SNPs were associated with H&N cancer risk, but the identified SNPs differed among males and females. Some of the SNPs were related to immune response genes. The immune response gene SNPs were also related to survival. In particular, we noted that the tumor necrosis factor alpha (TNFα) rs1800629 could have an influence on cancer risk, tumor recurrence as well as survival. Genetic variation of the TNFα rs1800629 might be useful as a biomarker in clinical decision-making since it was found to be related to cancer risk, tumor recurrence, and survival of H&N cancer patients. © 2016 S.

    Full Text Available Background: Chemoradiotherapy is an established strategy for organ preservation in head-neck cancer. These protocols are associated with added toxicity and need support infrastructure. Practice setup and availability of resources vary at the community level in developing countries. Aim: To evaluate the feasibility of organ-preservation strategies in different settings in developing countries. Settings and Design : Survey. Materials and Methods: In a questionnaire-based study, questions were directed to clinicians with varied practice setups to gather information regarding infrastructure, finance, and feasibility of organ-preservation protocols and their current practice trends. Statistical Analysis: Descriptive. Results: Responses from 100 clinicians with focused practice in head-neck oncology were analyzed. Sixty-one percent clinicians were practicing organ preservation for advanced head-neck cancers in their practice. However, 65% centers lacked sufficient infrastructure to support organ-preservation protocols. Forty percent patients were treated on cobalt-radiotherapy machine. Fifty-nine percent of clinicians suggested that less than third of their patients were fit to undergo chemoradiation and 67% believed that adherence to treatment protocol was observed in less than two-thirds of cases. Based on their experience 82% clinicians felt that only one-third patients requiring salvage would actually undergo treatment. The majority of the patients (68% used personal funds for treatment and less than one-third of the patients could afford complete treatment. Conclusions: The infrastructure needed to support organ-preservation protocols varies significantly between centers in developing countries. It may not be feasible to perform organ-preservation strategies in certain centers and feasibility guidelines should be made for their judicious use in developing countries.

    Background: The TNM classification system of tumor stage does not always reflect the actual tumor mass present at diagnosis. This study aimed at evaluating the prognostic value of volumetric data regarding survival in head and neck cancer patients being treated with either cisplatin or carboplatin administered concomitantly with radiotherapy. Patients and Methods: We retrospectively analyzed 107 patients suffering from squamous cell carcinoma of the head and neck in a Greek-German cooperational study (see Table 1). All patients were treated by radiotherapy and concomitant chemotherapy. 65 patients received chemotherapy with carboplatin and 42 with cisplatin. More than 6,200 CT scans were analyzed by digitalization of contours which subsequently led to the computation of the tumor volume (primary and macroscopic lymph node metastases). Results: Median follow-up was 43 months and median survival 30 months. Median initial tumor volume was 32.5 ml (range 2.1-220.1 ml) in the carboplatin and 44.4 ml (range 3.2-202.5 ml) in the cisplatin group (see Figure 1). After treatment, tumor volumes did not differ significantly (median of 3.1 ml [range 0.0-167.1 ml] and 3.5 ml [range 0.0-166.0 ml], respectively). 41 patients (63.1%) died in the carboplatin group and 22 patients (52.4%) in the cisplatin group (see Figure 2). Pretherapeutic tumor volume was prognostic with respect to survival while TNM classification and age were not. Pretherapeutic tumor volume was negatively and percent decrease in tumor volume positively associated with survival (see Tables 2 and 3). Conclusion: Knowledge of the initial tumor volume adds valuable information in terms of prognosis. Initial tumor volume should be included in all future clinical trials regarding head and neck cancer patients. (orig.)

    Diffuse optical tomography using near-infrared light in a wavelength range from 700 to 1000 nm has the potential to enable non-invasive diagnoses of thyroid cancers; some of which are difficult to detect by conventional methods such as ultrasound tomography. Diffuse optical tomography needs to be based on a physically accurate model of light propagation in the neck, because it reconstructs tomographic images of the optical properties in the human neck by inverse analysis. Our objective here was to investigate the effects of three factors on light propagation in the neck using the 2D time-dependent radiative transfer equation: (1) the presence of the trachea, (2) the refractive-index mismatch at the trachea-tissue interface, and (3) the effect of neck organs other than the trachea (spine, spinal cord, and blood vessels). There was a significant influence of reflection and refraction at the trachea-tissue interface on the light intensities in the region between the trachea and the front of the neck surface. Organs other than the trachea showed little effect on the light intensities measured at the front of the neck surface although these organs affected the light intensities locally. These results indicated the necessity of modeling the refractive-index mismatch at the trachea-tissue interface and the possibility of modeling other neck organs simply as a homogeneous medium when the source and detectors were far from large blood vessels.

    Late oral mucosa changes after radiotherapy for head and neck cancer have been poorly studied. This study aimed to determine long-term effects of radiotherapy on oral mucosa using exfoliative oral cytology. Fifty patients with cancer were enrolled, five of whom in order to validate microscopic analysis. Smears were collected at programmed visit; a score was used to rank possible cytological alterations. Presence of inflammation was also microscopically described and compared to blood count tests. Epithelial cells revealed a peculiar 'folding' phenotype, not related to chemotherapy, total dose, or to the effective dose delivered to mucosa. Inflammation described was related to the score for 'folding' cells; moreover, score decreased in the presence of a higher lymphocyte count, while it was not altered by neutrophil count. We suggest application of exfoliative cytology to study radiation injury and the variability of individual response of oral mucosa to radiation.

    We investigated the association between diet and head and neck cancer (HNC) risk using data from the International Head and Neck Cancer Epidemiology (INHANCE) consortium. The INHANCE pooled data included 22 case-control studies with 14,520 cases and 22,737 controls. Center-specific quartiles among the controls were used for food groups, and frequencies per week were used for single food items. A dietary pattern score combining high fruit and vegetable intake and low red meat intake was created. Odds ratios (OR) and 95% confidence intervals (CI) for the dietary items on the risk of HNC were estimated with a two-stage random-effects logistic regression model. An inverse association was observed for higher-frequency intake of fruit (4th vs. 1st quartile OR = 0.52, 95% CI = 0.43-0.62, p (trend) < 0.01) and vegetables (OR = 0.66, 95% CI = 0.49-0.90, p (trend) = 0.01). Intake of red meat (OR = 1.40, 95% CI = 1.13-1.74, p (trend) = 0.13) and processed meat (OR = 1.37, 95% CI = 1.14-1.65, p (trend) < 0.01) was positively associated with HNC risk. Higher dietary pattern scores, reflecting high fruit\\/vegetable and low red meat intake, were associated with reduced HNC risk (per score increment OR = 0.90, 95% CI = 0.84-0.97).

    The use of small antimicrobial peptides or bacteriocins, like nisin, to treat cancer is a new approach that holds great promise. Nisin exemplifies this new approach because it has been used safely in humans for many years as a food preservative, and recent laboratory studies support its anti-tumor potential in head and neck cancer. Previously, we showed that nisin (2.5%, low content) has antitumor potential in head and neck squamous cell carcinoma (HNSCC) in vitro and in vivo. The current studies explored a naturally occurring variant of nisin (nisin ZP; 95%, high content) for its antitumor effects in vitro and in vivo. Nisin ZP induced the greatest level of apoptosis in HNSCC cells compared to low content nisin. HNSCC cells treated with increasing concentrations of nisin ZP exhibited increasing levels of apoptosis and decreasing levels of cell proliferation, clonogenic capacity, and sphere formation. Nisin ZP induced apoptosis through a calpain-dependent pathway in HNSCC cells but not in human oral keratinocytes. Nisin ZP also induced apoptosis dose-dependently in human umbilical vein endothelial cells (HUVEC) with concomitant decreases in vascular sprout formation in vitro and reduced intratumoral microvessel density in vivo. Nisin ZP reduced tumorigenesis in vivo and long-term treatment with nisin ZP extended survival. In addition, nisin treated mice exhibited normal organ histology with no evidence of inflammation, fibrosis or necrosis. In summary, nisin ZP exhibits greater antitumor effects than low content nisin, and thus has the potential to serve as a novel therapeutic for HNSCC.

  6. Epigenetic Modifications and Head and Neck Cancer: Implications for Tumor Progression and Resistance to Therapy

    Full Text Available Head and neck squamous carcinoma (HNSCC is the sixth most prevalent cancer and one of the most aggressive malignancies worldwide. Despite continuous efforts to identify molecular markers for early detection, and to develop efficient treatments, the overall survival and prognosis of HNSCC patients remain poor. Accumulated scientific evidences suggest that epigenetic alterations, including DNA methylation, histone covalent modifications, chromatin remodeling and non-coding RNAs, are frequently involved in oral carcinogenesis, tumor progression, and resistance to therapy. Epigenetic alterations occur in an unsystematic manner or as part of the aberrant transcriptional machinery, which promotes selective advantage to the tumor cells. Epigenetic modifications also contribute to cellular plasticity during tumor progression and to the formation of cancer stem cells (CSCs, a small subset of tumor cells with self-renewal ability. CSCs are involved in the development of intrinsic or acquired therapy resistance, and tumor recurrences or relapse. Therefore, the understanding and characterization of epigenetic modifications associated with head and neck carcinogenesis, and the prospective identification of epigenetic markers associated with CSCs, hold the promise for novel therapeutic strategies to fight tumors. In this review, we focus on the current knowledge on epigenetic modifications observed in HNSCC and emerging Epi-drugs capable of sensitizing HNSCC to therapy.

    Full Text Available Abstract Background To report about early clinical experience in radiation treatment of head and neck cancer of different sites and histology by volumetric modulated arcs with the RapidArc technology. Methods During 2009, 45 patients were treated at Istituto Clinico Humanitas with RapidArc (28 males and 17 females, median age 65 years. Of these, 78% received concomitant chemotherapy. Thirty-six patients were treated as exclusive curative intent (group A, three as postoperative curative intent (group B and six with sinonasal tumours (group C. Dose prescription was at Planning Target Volumes (PTV with simultaneous integrated boost: 54.45Gy and 69.96Gy in 33 fractions (group A; 54.45Gy and 66Gy in 33 fractions (group B and 55Gy in 25 fractions (group C. Results Concerning planning optimization strategies and constraints, as per PTV coverage, for all groups, D98% > 95% and V95% > 99%. As regards organs at risk, all planning objectives were respected, and this was correlated with observed acute toxicity rates. Only 28% of patients experienced G3 mucositis, 14% G3 dermitis 44% had G2 dysphagia. Nobody required feeding tubes to be placed during treatment. Acute toxicity is also related to chemotherapy. Two patients interrupted the course of radiotherapy because of a quick worsening of general clinical condition. Conclusions These preliminary results stated that volumetric modulated arc therapy in locally advanced head and neck cancers is feasible and effective, with acceptable toxicities.

    Full Text Available Introduction: Inspite of various strategies adopted to protect the sensitive structures during organ preservation strategies, radiation damage can occur from the pharyngotympanic tube to the brain stem auditory pathway causing hearing loss. The purpose of this study is to evaluate the audiometric abnormalities and characterize them among the patients of head and neck cancers who have undergone radiotherapy (RT and chemoradiation therapy (CT+RT. Materials and Methods: Sixty-six histopathologically proven head and neck cancer patients receiving RT and 34 patients receiving concomitant CT + RT underwent evaluation for audiometric abnormalities from 1 st September 2010 to 31 st August 2012. Results: Hearing losses were predominately of sensorineural type and mild. Patients who received concomitant CT+RT experienced greater sensorineural hearing loss compared with patients treated with RT alone. A paired sample t-test was conducted to compare the hearing losses before therapy and 6 and 12 months after therapy and was found to be significant ( P < 0.05. It was found that hearing loss was persistent. Significant difference was found in the proportion of hearing loss after RT and RT+CT ( P < 0.05 after 1 month. In addition, mixed hearing loss occurred due to damage to the middle ear contents and can be improved if intervened appropriately.

  9. Hypoxia in Head and Neck Cancer in Theory and Practice: A PET-Based Imaging Approach

    Loredana G. Marcu

    2014-01-01

    Full Text Available Hypoxia plays an important role in tumour recurrence among head and neck cancer patients. The identification and quantification of hypoxic regions are therefore an essential aspect of disease management. Several predictive assays for tumour oxygenation status have been developed in the past with varying degrees of success. To date, functional imaging techniques employing positron emission tomography (PET have been shown to be an important tool for both pretreatment assessment and tumour response evaluation during therapy. Hypoxia-specific PET markers have been implemented in several clinics to quantify hypoxic tumour subvolumes for dose painting and personalized treatment planning and delivery. Several new radiotracers are under investigation. PET-derived functional parameters and tracer pharmacokinetics serve as valuable input data for computational models aiming at simulating or interpreting PET acquired data, for the purposes of input into treatment planning or radio/chemotherapy response prediction programs. The present paper aims to cover the current status of hypoxia imaging in head and neck cancer together with the justification for the need and the role of computer models based on PET parameters in understanding patient-specific tumour behaviour.

    Full Text Available The aim of this study was to evaluate the effectiveness of acupuncture in minimizing the severity of radiation-induced xerostomia in patients with head and neck cancer. A total of 24 consecutive patients receiving > 5000 cGy radiotherapy (RT involving the major salivary glands bilaterally were assigned to either the preventive acupuncture group (PA, n = 12, treated with acupuncture before and during RT, or the control group (CT, n = 12, treated with RT and not receiving acupuncture. After RT completion, clinical response was assessed in all patients by syalometry, measuring the resting (RSFR and stimulated (SSFR salivary flow rates, and by the visual analogue scale (VAS regarding dry mouth-related symptoms. Statistical analyses were performed with repeated-measures using a mixed-effect modeling procedure and analysis of variance. An alpha level of 0.05 was accepted for statistical significance. Although all patients exhibited some degree of impairment in salivary gland functioning after RT, significant differences were found between the groups. Patients in the PA group showed improved salivary flow rates (RSFR, SSFR; p < 0.001 and decreased xerostomia-related symptoms (VAS, p < 0.05 compared with patients in the CT group. Although PA treatment did not prevent the oral sequelae of RT completely, it significantly minimized the severity of radiation-induced xerostomia. The results suggest that acupuncture focused in a preventive approach can be a useful therapy in the management of patients with head and neck cancer undergoing RT.

    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. PMID:23955053

  12. Piezoresistive Membrane Surface Stress Sensors for Characterization of Breath Samples of Head and Neck Cancer Patients

    Directory of Open Access Journals (Sweden)

    Hans Peter Lang

    2016-07-01

    Full Text Available For many diseases, where a particular organ is affected, chemical by-products can be found in the patient’s exhaled breath. Breath analysis is often done using gas chromatography and mass spectrometry, but interpretation of results is difficult and time-consuming. We performed characterization of patients’ exhaled breath samples by an electronic nose technique based on an array of nanomechanical membrane sensors. Each membrane is coated with a different thin polymer layer. By pumping the exhaled breath into a measurement chamber, volatile organic compounds present in patients’ breath diffuse into the polymer layers and deform the membranes by changes in surface stress. The bending of the membranes is measured piezoresistively and the signals are converted into voltages. The sensor deflection pattern allows one to characterize the condition of the patient. In a clinical pilot study, we investigated breath samples from head and neck cancer patients and healthy control persons. Evaluation using principal component analysis (PCA allowed a clear distinction between the two groups. As head and neck cancer can be completely removed by surgery, the breath of cured patients was investigated after surgery again and the results were similar to those of the healthy control group, indicating that surgery was successful.

    One third of the patients had cachexia with an association of significantly shorter survival. These results suggest that combining HGS and MAMA seems to be a practical method to screen cachexia in patients with head and neck cancer and may also be used when assessing their prognosis. The aim of this study was to analyze the hypothesis that cachexia defined as both low mid-arm muscle area (MAMA) and handgrip strength (HGS) is associated with decreased survival in patients with head and neck squamous cell carcinoma (HNSCC). Sixty-five consecutive patients with primary HNSCC were enrolled prior to cancer therapy. Cachexia was defined as low handgrip strength (HGS) and low mid-arm muscle area (MAMA). Nutritional status was assessed by patient-generated subjective global assessment (PG-SGA) and sarcopenia by low MAMA. Biochemical parameters reflecting nutritional status and S-25-OHD were measured. Cachexia was seen in 31% and sarcopenia in 46% of patients. Altogether, 34% of patients were malnourished. Disease-free survival was 13 months (3-62) in cachectic patients, compared with 66 months (31-78) in non-cachectic patients (p = 0.009). S-25-OHD was 28 nmol/l in cachectic patients, compared with 46 nmol/l in non-cachectic patients (p = 0.009) and prealbumin 187 mg/l and 269 mg/l, respectively (p < 0.001).

  15. Basics of tumor development and importance of human papilloma virus (HPV for head and neck cancer [

    Full Text Available [english] Head and Neck Squamous Cell Carcinomas (HNSCC are the 6 most common cancers worldwide. While incidence rates for cancer of the hypopharynx and larynx are decreasing, a significant increase in cancer of the oropharynx (OSCC is observed. Classical risk factors for HNSCC are smoking and alcohol. It has been shown for 25 to 60% of OSCC to be associated with an infection by oncogenic human papilloma viruses (HPV. The development of “common” cancer of the head and neck is substantially enhanced by an accumulation of genetic changes, which lead to an inactivation of tumor suppressor genes or activation of proto-oncogenes. A more or less uniform sequence of different DNA-damages leads to genetic instability. In this context, an early and frequent event is deletion on the short arm of chromosome 9, which results in inactivation of the p16-gene. In contrast, for HPV-induced carcinogenesis, expression of the viral proteins E6 and E7 is most important, since they lead to inactivation of the cellular tumor-suppressor-proteins p53 and Rb. The natural route of transoral infection is a matter of debate; peroral HPV-infections might be frequent and disappear uneventfully in most cases. Smoking seems to increase the probability for developing an HPV-associated OSCC. The association of HNSCC with HPV can be proven with established methods in clinical diagnostics. In addition to classical prognostic factors, diagnosis of HPV-association may become important for selection of future therapies. Prognostic relevance of HPV probably surmounts many known risk-factors, for example regional metastasis. Until now, no other molecular markers are established in clinical routine. Future therapy concepts may vary for the two subgroups of patients, particularly patients with HPV-associated OSCC may take advantage of less aggressive treatments. Finally, an outlook will be given on possible targeted therapies.

    Low body mass index (BMI) has been associated with risk of head-neck cancer (HNC), but prospective data are scarce. We investigated the association between BMI, BMI at age 20 years and change in BMI during adulthood with risk of HNC and HNC subtypes. 120,852 participants completed a questionnaire on diet and other cancer risk factors, including anthropometric measurements, at baseline in 1986. After 20.3 years of follow-up, 411 HNC (127 oral cavity cancer (OCC), 84 oro-/hypopharyngeal cancer (OHPC), and 197 laryngeal cancer (LC)) cases and 3,980 subcohort members were available for case-cohort analysis using Cox proportional hazards models. BMI at baseline was inversely associated with risk of HNC overall, with a multivariate rate ratio of 3.31 (95% CI 1.40–7.82) for subjects with a BMI < 18.5 kg/m2, compared to participants with a BMI of 18.5 to 25 kg/m2. Among HNC subtypes, this association was strongest for OCC and OHPC. The association between BMI at age 20 and HNC risk appeared to be positive. In this large prospective cohort study, we found an inverse association between BMI at baseline and HNC risk. For BMI at age 20, however, a positive rather than inverse association was found.

    Highlights: • Simultaneous PET/MRI is a suitable tool for head/neck T-staging. • No significant differences have been found for PET measures get by both PET/CT and PET/MRI. • SUV 2D and 3D measures in HN lesion offer comparable estimations. • Multiparametric evaluation allows a complete characterization of HN lesions. - Abstract: Purpose: To evaluate the role of simultaneous hybrid PET/MR imaging and to correlate metabolic PET data with morpho-functional parameters derived by MRI in patients with head–neck cancer. Methods: Forty-four patients, with histologically confirmed head and neck malignancy (22 primary tumors and 22 follow-up) were studied. Patients initially received a clinical exam and endoscopy with direct biopsy. Next patients underwent whole body PET/CT followed by PET/MR of the head/neck region. PET and MRI studies were separately evaluated by two blinded groups (both included one radiologist and one nuclear physician) in order to define the presence or absence of lesions/recurrences. Regions of interest (ROIs) analysis was conducted on the primary lesion at the level of maximum size on metabolic (SUV and MTV), diffusion (ADC) and perfusion (K{sup trans}, V{sub e}, k{sub ep} and iAUC) parameters. Results: PET/MR examinations were successfully performed on all 44 patients. Agreement between the two blinded groups was found in anatomic allocation of lesions by PET/MR (Primary tumors: Cohen's kappa 0.93; Follow-up: Cohen's kappa 0.89). There was a significant correlation between CT-SUV measures and MR (e.g., CT-SUV VOI vs. MR-SUV VOI: ρ = 0.97, p < 0.001 for the entire sample). There was also significant positive correlations between the ROI area, SUV measures, and the metabolic parameters (SUV and MTV) obtained during both PET/CT and PET/MR. A significant negative correlation was observed between ADC and K{sup trans} values in the primary tumors. In addition, a significant negative correlation existed between MR SUV and ADC in

    Patients undergoing treatment for head and neck cancer may develop myofascial pain syndrome as sequelae. The purpose of this study was to determine the prevalence, risk factors, and quality of life (QOL) related to myofascial pain syndrome. This was a prospective study including patients with head and neck cancer with at least a 1-year disease-free interval. One hundred sixty-seven patients were analyzed, and myofascial pain syndrome was diagnosed in 20 (11.9%). In the multivariate analysis, hypopharyngeal tumors (odds ratio [OR] = 6.35; 95% confidence interval [CI] = 1.58-25.56) and neck dissection (OR = 3.43; 95% CI = 1.16-10.17) were independent factors for myofascial pain syndrome.

    Treatment options for head and neck cancer are limited, and can cause an impaired ability to eat, talk, and breathe. Therefore, optimized and personalized therapies could reduce unnecessary toxicities from ineffective treatments. Organoids are generated from primary tumor tissue and provide a physiologically-relevant in vitro model to measure drug response. Additionally, multiphoton fluorescence lifetime imaging (FLIM) of the metabolic cofactors NAD(P)H and FAD can resolve dynamic cellular response to anti-cancer treatment. This study applies FLIM of NAD(P)H and FAD to head and neck cancer organoids. Head and neck cancer tissue was digested and grown in culture as three-dimensional organoids. Gold standard measures of therapeutic response in vivo indicate stable disease after treatment with cetuximab (antibody therapy) or cisplatin (chemotherapy), and treatment response after combination treatment. In parallel, organoids were treated with cetuximab, cisplatin, or combination therapy for 24 hours. Treated organoids exhibit decreased NAD(P)H lifetime (pquality of life and treatment outcomes for head and neck cancer patients.

    Estimation of attributable fractions for tobacco and alcohol, and investigation of the association between body mass index (BMI) and head and neck cancer risk have largely been in case-control studies. These aspects and physical activity need to be assessed as possible head and neck cancer risk/protective factors in a cohort study. In the Prostate, Lung, Colorectal, and Ovarian (PLCO) cancer screening trial, of the 101,182 study subjects, 177 individuals developed head and neck cancer. The proportion of head and neck cancer cases attributed to tobacco and/or alcohol was 66% (50.5% tobacco alone, 14.7% alcohol alone, 0.9% tobacco and alcohol combined). BMI was not associated with head and neck cancer risk, but increasing hours of physical activity per week was associated with a reduced head and neck cancer risk (odds ratio [OR] = 0.58; 95% confidence interval [CI] = 0.35-0.96). Cigarette smoking is clearly the most important head and neck cancer risk factor in this population. The reduced cancer risk due to physical activity was consistent with results from a pooled analysis of case-control studies. Copyright © 2012 Wiley Periodicals, Inc.

    Endometrial adenocarcinomas rank third as tumoral sites en France. The tumors are confined to the uterus in 80% of the cases. Brachytherapy has a large place in the therapeutic strategy. The gold standard treatment remains extra-fascial hysterectomy with bilateral annexiectomy and bilateral internal iliac lymph node dissection. However, after surgery alone, the rate of locoregional relapses reaches 4-20%, which is reduced to 0-5% after postoperative brachytherapy of the vaginal cuff. This postoperative brachytherapy is delivered as outpatients treatment, by 3 or 4 fractions, at high dose rate. The utero-vaginal preoperative brachytherapy remains well adapted to the tumors which involve the uterine cervix. Patients presenting a localized tumor but not operable for general reasons (< 10%) can be treated with success by exclusive irradiation, which associates a pelvic irradiation followed by an utero-vaginal brachytherapy. A high local control of about 80-90% is obtained, a little lower than surgery, with a higher risk of late complications. Last but not least, local relapses in the vaginal cuff, or in the perimeatic area, can be treated by interstitial salvage brachytherapy, associated if possible with external beam irradiation. The local control is reached in half of the patients, but metastatic dissemination is frequent. We conclude that brachytherapy has a major role in the treatment of endometrial adenocarcinomas, in combination with surgery, or with external beam irradiation for not operable patients or in case of local relapses. It should use new technologies now available including computerized after-loaders and 3D dose calculation. (authors)

    Trismus is one of the common late side effects of radiotherapy (RT) of head and neck cancers. It occurs in about 30% of patients treated by telecobalt. It, in turn, leads to significant morbidity, including malnutrition, difficulty in speaking, and compromised oral hygiene with severe psychosocial, and economic impacts. To determine the prevalence of trismus and its progression in patients who have received radical concurrent chemoradiation for head and neck cancer by telecobalt at our institution. To note the effect of early rehabilitative measures on the severity of trismus and to assess its impact on the quality of life (QOL). A total of 47 evaluable patients of head and neck cancer patients treated by telecobalt with radical intent between January 2012 and December 2013 were analyzed and baseline maximal inter-incisal opening (MIO) and MIO at the completion of RT, after 3 months, 6 months, and 1 year, after completion of RT were noted. Grading of trismus was done using Modified Common Toxicity Criteria (CTCAE Version 3.0). QOL assessment was done using European Organization for Research and Treatment of Cancer QLQ-HN35. The time when the rehabilitative measures were started were also noted. Chi-square test with Fisher exact probability test and Students t-test. Radiation-induced trismus (RIT) was seen in 31.9%, 34.04%, and 38.39% of cases at 3, 6, and 12 months after completion of RT. Grade II and III trismus accounted for 17.02% and 6.38% at the end of 1 year. Patients who started regular rehabilitative exercises soon, after completion of RT had a better mean MIO as compared to those who were not compliant (32 mm vs. 24 mm at 1 year), and there was a trend toward delayed progression in them. Trismus was also seen to adversely affect QOL of the patients. RIT is a major cause for late morbidity in patients treated with conventional RT leading to poor QOL. Early rehabilitative measures are useful in preventing progression of trismus.

    This study investigates cutoff scores for the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30-questions (EORTC QLQ-C30) and head and neck cancer-specific module (QLQ-H&N35) to identify patients with head and neck cancer who may require clinical attention. Ninety-six patients with head and neck cancer completed the EORTC QLQ-C30/H&N35 and questions on supportive care needs. For all EORTC domains with the ability to discriminate between patients with and without unmet needs (area under the receiver operating characteristic curve [AUC] ≥0.70), the accuracy (eg, sensitivity and specificity) of potential cutoff scores were calculated. Cutoff scores (sensitivity ≥0.80 and specificity ≥0.60) of 90 (functioning domains) and 5 to 10 (symptom domains) were found on 7 of 28 continuous EORTC QLQ-C30/H&N35 domains. Borderline cutoff scores (sensitivity ≥0.70 and specificity ≥0.60 or sensitivity ≥0.80 and specificity ≥0.50) were found on 5 other domains. This study provided cutoff scores on the EORTC QLQ-C30 and H&N35 based on patients' perceptions of their needs for supportive care. Future research is needed on the replicability of these cutoff scores. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1493-E1500, 2016. © 2015 Wiley Periodicals, Inc.

    Cigarette smoking and excessive alcohol drinking result in the rise of numbers of patients suffering from the head and neck cancer. Addiction to any of these stimulants carry a risk of developing a cancerogenesis process. Using them simultaniously lead not to a summary of each of those risks but multiplies them. Scientific research also indicates the important difference in the incidence of cancer in people who have never smoked cigarettes or drunk alcohol in comparison to those, whose exposure to these stimulatns was longterm - in such case, the former group had a lower percentage of developing the disease. Human body burdened with the ongoing cancer shows disturbances on various levels of the system. One of such disturbances is change of the concetration levels of physiological metals, such as calcium, magnesium, iron, copper, zinc or mangenese. They play key roles in maintaing the hormonal and ionic stability, they act as cofactors in many enzymes in metabolic processes. Diagnostic research of any deviations in levels of those essential elements enables a full estimation of a patient condition. The aim of this study was physiological metal levels evaluation in different kinds of biological material in patients with tumors of larynx, salivary glands and oral cavity and tongue. Hair and nail samples were used as examples of alternative material, beside the serum samples, which is a standard material and often used. Subjects were patients of Otolaryngology and Laryngological Oncology Clinic of Poznan University of Medical Sciences (Samodzielny Publiczny Szpital Kliniczny nr 2 im.

    Recent clinical trials have demonstrated a clear survival advantage in advanced head and neck squamous cell carcinoma (HNSCC) patients treated with immune checkpoint blockade. These emerging results reveal that HNSCC is one of the most promising frontiers for immunotherapy research. However, further progress in head and neck immuno-oncology will require a detailed understanding of the immune infiltrative landscape found in these tumors. We leveraged transcriptome data from 280 tumors profiled by The Cancer Genome Atlas (TCGA) to comprehensively characterize the immune landscape of HNSCC in order to develop a rationale for immunotherapeutic strategies in HNSCC and guide clinical investigation. We find that both HPV+ and HPV– HNSCC tumors are among the most highly immune-infiltrated cancer types. Strikingly, HNSCC had the highest median Treg/CD8+ T cell ratio and the highest levels of CD56dim NK cell infiltration, in our pan-cancer analysis of the most immune-infiltrated tumors. CD8+ T cell infiltration and CD56dim NK cell infiltration each correlated with superior survival in HNSCC. Tumors harboring genetic smoking signatures had lower immune infiltration and were associated with poorer survival, suggesting these patients may benefit from immune agonist therapy. These findings illuminate the immune landscape of HPV+ and HPV– HNSCC. Additionally, this landscape provides a potentially novel rationale for investigation of agents targeting modulators of Tregs (e.g., CTLA-4, GITR, ICOS, IDO, and VEGFA) and NK cells (e.g., KIR, TIGIT, and 4-1BB) as adjuncts to anti–PD-1 in the treatment of advanced HNSCC.

    This study aims to describe the prevalence of alcohol consumption in patients diagnosed with an upper aerodigestive tract cancer (UADTC) and evaluate the clinical impact of head and neck surgeons' recommendations on alcohol intake. An observational, retrospective, and cross-sectional study was conducted. Socio-demographic data, type of cancer, psychiatric history, substance-use history, and DSM-IV-TR criteria for alcohol dependence were recorded. Patients were asked to report their alcohol consumption before UADTC diagnosis and during their follow-up. All patients were asked if they had received from the specialist any recommendation to reduce or stop their alcohol consumption. One hundred ninety-one patients were included. Laryngeal cancer was the most frequent. 85.3% of patients were alcohol consumers before being diagnosed, 39.8% were risky drinkers, and 13.1% had alcohol dependence. The prevalence of alcohol use decreased by 16.7% after the UADTC was diagnosed. The proportion of risky drinkers decreased from 46.6% to 24.5%. Almost half of the patients did not recall having received any recommendation regarding alcohol consumption. Receiving a recommendation was independently associated with a positive response (reduced or stopped alcohol consumption) with an Odds Ratio 3.7; p < 0.001. Prevalence of alcohol dependence and risky drinking (39.8%) is high in UADTC patients, compared to the general population. Otorhinolaryngologists and head and neck surgeons frequently provide recommendations about alcohol consumption, which has a relevant impact on the reduction of alcohol intake. Further prospective studies focused on brief advice should be performed in order to demonstrate effectiveness in this population.

    Full Text Available Abstract Background Head and neck squamous cell carcinoma (HNSCC is a highly lethal cancer that contains cellular and functional heterogeneity. Previously, we enriched a subpopulation of highly tumorigenic head and neck cancer initiating cells (HN-CICs from HNSCC. However, the molecular mechanisms by which to govern the characteristics of HN-CICs remain unclear. GRP78, a stress-inducible endoplasmic reticulum chaperone, has been reported to play a crucial role in the maintenance of embryonic stem cells, but the role of GRP78 in CICs has not been elucidated. Results Initially, we recognized GRP78 as a putative candidate on mediating the stemness and tumorigenic properties of HN-CICs by differential systemic analyses. Subsequently, cells with GRP78 anchored at the plasma membrane (memGRP78+ exerted cancer stemness properties of self-renewal, differentiation and radioresistance. Of note, xenotransplantation assay indicated merely 100 memGRP78+ HNSCCs resulted in tumor growth. Moreover, knockdown of GRP78 significantly reduced the self-renewal ability, side population cells and expression of stemness genes, but inversely promoted cell differentiation and apoptosis in HN-CICs. Targeting GRP78 also lessened tumorigenicity of HN-CICs both in vitro and in vivo. Clinically, co-expression of GRP78 and Nanog predicted the worse survival prognosis of HNSCC patients by immunohistochemical analyses. Finally, depletion of GRP78 in HN-CICs induced the expression of Bax, Caspase 3, and PTEN. Conclusions In summary, memGRP78 should be a novel surface marker for isolation of HN-CICs, and targeting GRP78 signaling might be a potential therapeutic strategy for HNSCC through eliminating HN-CICs.

    Full Text Available Introduction: Causes of head and neck cancers (HNCs are multifactorial, and few studies have investigated the association between chemical exposure and HNCs. The objective of this study was to investigate associations between HNCs, agricultural occupations, and pesticide exposure. The potential for the accumulation of pesticides in the adipose tissue of patients was also investigated.   Materials and Methods: A structured questionnaire was used to collect information on demographics, occupation, and exposure to pesticides in a hospital-based case-control study. Pesticide residue in the adipose tissue of the neck in both cases and controls was also monitored via gas chromatography–mass spectroscopy.   Results: Thirty-one HNC cases were included in this study as well as 32 gender-, age-, and smoking-matched controls. An agricultural occupation was associated with HNC (odds ratio [OR], 3.26; 95% confidence interval [CI], 1.13–9.43 after controlling for age, sex, and smoking. Pesticide exposure was associated with total HNC cases (OR, 7.45; 95% CI, 1.78–3.07 and larynx cancer (OR, 9.33; 95% CI, 1.65–52.68. A dose-response pattern was observed for HNC cases (P=0.06 and larynx cancer (P=0.01. In tracing the pesticide residue, five chlorinated pesticides, namely dichlorodiphenyltrichloroethane (DDT, dichlorodipheny-ldichloroethane (DDD, dichlorodiphenyldichloroethylene (DDE, dieldrin, and lindane, were identified in the adipose tissue. Chlorinated pesticide detection was significantly associated with HNC (OR, 3.91; 95% CI 0.9–0.16.9.   Conclusion: HNCs were found to be associated with pesticide exposure after controlling for confounders. A high education level was identified as a modifying factor decreasing the risk of HNCs. Further studies with larger number of subjects are recommended to assess these relationships in greater detail.

    Recent results of the Cancer Genome Atlas on head and neck squamous cell carcinoma (HNSCC) revealed that HNSCC lacked predominant gain-of-function mutations in oncogenes, whereas an essential role for epigenetics in oncogenesis has become apparent. In parallel, it has gained general acceptance that cancer is considered as complex adaptive system, which evolves responding environmental selective pressures. This somatic evolution appears to proceed concurrently with the acquisition of an atavistic pluripotent state (i.e., “stemness”), which is inducible by intrinsic epigenetic reprogramming program as demonstrated by induced pluripotent stem (iPS) cells. This Nobel prize-winning discovery has markedly accelerated and expanded cancer stem cell research from the point of epigenetic reprogramming. Taken together, we hypothesize that stress-triggered atavistic reprogramming (STAR) may be the major driving force of HNSCC evolution. In this perspective, we discuss the possible mechanisms of STAR in HNSCC, focusing on recent topics of epigenetic reprogramming in developmental and cancer cell biology. PMID:27429838

    The mouth and oropharynx cancer is the 6{sup th} most common type of cancer in the world. The treatment may involve surgery, chemotherapy and radiotherapy. More than 50% of drugs against cancer were isolated from natural sources, such as Catharanthus roseus and epipodophyllotoxin, isolated from Podophyllum. The biggest challenge is to maximize the control of the disease, while minimizing morbidity and toxicity to the surrounding normal tissues. The Erythroxylum suberosum is a common plant in the Brazilian Cerrado biome and is popularly known as 'cabelo-de-negro'. The objective of this study was to evaluate the cytotoxic activity of Erythroxylum suberosum plant extracts of the Brazilian Cerrado biome associated with radiotherapy in human cell lines of oral and hypopharynx carcinomas. Cells were treated with aqueous, ethanolic and hexanic extracts of Erythroxylum suberosum and irradiated at 4 Gy, 6 Gy and 8 Gy. Cytotoxicity was evaluated by MTT assay and the absorbance was measured at 570 nm in a Beckman Counter reader. Cisplatin, standard chemotherapy, was used as positive control. The use of Erythroxylum suberosum extracts showed a possible radiosensitizing effect in vitro for head and neck cancer. The cytotoxicity effect in the cell lines was not selective and it is very similar to the effect of standard chemotherapy. The aqueous extract of Erythroxylum suberosum, combined with radiotherapy was the most cytotoxic extract to oral and hypopharynx carcinomas. (author)

    Full Text Available Aim: The aim was to identify the literature and to assess the association between quality-of-life (QoL and head and neck cancer (HNC related outcomes systemically. Materials and Methods: The full articles published in English language bio-medical journals between 1992 and December 2014 were searched using Medline database. The keywords used for searching the articles include the combination of "health-related of QoL," "QoL," "HNC." The search limited only to the observational studies using questionnaires European Organization for Research and Treatment of Cancer (EORTC QLQ C 30 and EORTC QLQ H and N 35. Purely psychological studies were excluded. Results: A total of 5055 articles were retrieved, and 16 articles were selected for this review. Of 16 observational studies, 13 (81.25% were prospective cohort studies while remaining 3 (18.75% were cross-sectional studies. The main findings of the studies revealed that the treatment of HNC had a statistically significant influence on QoL. Others associated factors like age, female sex, duration of treatment, advance tumor, and site of the tumor has also the impact on QoL on patients suffering from HNC. Conclusion: This review provides evidence for a positive relationship between cancer-related outcomes and QoL. Assessment of QoL in relation to HNC with proper methodology and validated instruments is lacking hence there is a need for further evidence to support the relation between cancer and QoL.

    The aim was to retrospectively investigate trismus (reduced mandible mobility) development in specified head and neck (H&N) cancer diagnosis according to different radiotherapy dosage regimens. Sixty-nine out of 246 patients with different H&N cancer diagnoses and available maximum interincisal opening (MIO) measurements before and after treatment were analyzed according to age, gender, radiation dose, tumor site and stage, and Karnofsky Performance Status Scale index. MIO was measured over time (range: 3-48 months), with a cutoff criterion for trismus of 35 mm. Overall, 42% of the patients had post-treatment MIO trismus incidence was highest in patients treated for parotid gland tumors followed by those treated for nasopharyngeal cancers. The mean MIO values at baseline were significantly different (p=0.0078) between patients who developed trismus (i.e. MIO trismus patients also had significantly larger tumors (p=0.0437), poorer physical function before start of treatment (p=0.0344), and had more often received a higher total tumor radiation dose (p=0.0418). This study reports a high incidence of trismus in H&N cancer patients after treatment. Furthermore, it was found that poor physical function before the start of treatment and high external beam radiation therapy (EBRT) dosages (>50 Gy) were related to significantly more trismus. Future prospective studies are needed to provide a better understanding of different risk factors associated with trismus development, the impact on health-related quality of life, and the effects of early treatment.

    The aim of this study was to investigate the impact of structured exercise with jaw mobilizing devices on trismus and its effect on trismus symptomatology and health-related quality of life (HRQL) in head and neck (H&N) cancer patients. Fifty patients with H&N cancer and trismus, i.e. maximum interincisal opening (MIO) ≤ 35 mm participated in a structured intervention program with jaw exercise. The patients in the intervention group underwent a 10-week exercise program with regular follow-up. A control group comprising of 50 patients with trismus and H&N cancer were matched to the intervention group according to gender, tumor location, tumor stage, comorbidity and age. HRQL and trismus-related symptoms were assessed. The mean MIO improvement was 6.4 mm (4.8-8.0) and 0.7 (-0.3-1.7) mm in the intervention group and control group respectively, three months post-intervention commencement (p Trismus Questionnaire (GTQ) domains, i.e. jaw-related problems (p trismus (MIO) was also reflected in the patient-reported outcome questionnaires where the patients who underwent the structured exercise program after cancer treatment reported improvements in HRQL and less trismus-related symptoms compared to the control group.

    Most solid cancers including head and neck squamous carcinoma (HNSC) are believed to be initiated from and maintained by cancer stem cells (CSCs) that are responsible for treatment resistance, resulting in tumour relapse. Epigallocatechin-3-gallate (EGCG), the most abundant polyphenol in green tea, can potently inhibit cancer growth and induce apoptosis in various cancers, including HNSC. However, its effect on HNSC CSCs is not well elucidated. In this study, we examined the anti-tumour effect of EGCG on HNSC CSCs. We demonstrated that EGCG inhibits the self-renewal capacity of HNSC CSCs by suppressing their sphere forming capacity, and attenuates the expression of stem cell markers, such as Oct4, Sox2, Nanog and CD44. EGCG treatment augmented cisplatin-mediated chemosensitivity by suppressing ABCC2 and ABCG2 transporter genes, which are putative molecules of treatment resistance of CSC. In addition, the combination treatment of EGCG and cisplatin inhibited tumour formation and induced apoptosis in a xenograft model. As one of mechanisms of suppression of HNSC CSC traits, EGCG decreased the transcriptional level of Notch, resulting in the inhibition of Notch signalling. Collectively, our data suggest that EGCG in combination with cisplatin can be used for the management of HNSC CSCs.

  18. Receptor-Tyrosine-Kinase-Targeted Therapies for Head and Neck Cancer

    Full Text Available Molecular therapeutics for treating epidermal growth factor receptor-(EGFR- expressing cancers are a specific method for treating cancers compared to general cell loss with standard cytotoxic therapeutics. However, the finding that resistance to such therapy is common in clinical trials now dampens the initial enthusiasm over this targeted treatment. Yet an improved molecular understanding of other receptor tyrosine kinases known to be active in cancer has revealed a rich network of cross-talk between receptor pathways with a key finding of common downstream signaling pathways. Such cross talk may represent a key mechanism for resistance to EGFR-directed therapy. Here we review the interplay between EGFR and Met and the type 1 insulin-like growth factor receptor (IGF-1R tyrosine kinases, as well as their contribution to anti-EGFR therapeutic resistance in the context of squamous cell cancer of the head and neck, a tumor known to be primarily driven by EGFR-related oncogenic signals.

    2007-09-15

    Purpose: To assess the feasibility and acute/delayed toxicity of pulsed-dose-rate brachytherapy (PDR BT) in head-and-neck tumors. Patients and Methods: 45 head and neck cancer patients underwent interstitial or contact PDR BT at a dose of 10.2-70 Gy (median, 70 Gy) and 0.6 or 1.0 Gy/pulse/h. 42 patients were administered BT as part of their curative treatment; 32 of them had sole BT. Three reirradiated patients with recurrent tumor had palliative BT. Results: PDR BT was well tolerated. Intense bleeding was the only complication associated with catheter removal from the tongue and bucca. 44 patients who completed BT experienced acute mucositis. Grade 3 toxicity of skin and oral mucosa occurred in three (6.8%) and six patients (13.6%), respectively. At a median follow-up of 22 months (range, 2-67 months), late serious toxicity (grade 4, for soft tissue and bone) was seen in seven patients (15.9%). Among the parameters analyzed, only dental care performed before BT had a significant impact on mucosal side effects. Acute severe mucositis was observed in 23% of patients without dental care compared to 0% of those with dental care (p = 0.044). Late severe mucositis occurred in 17.7% and 26.9% of the respective patients (p = 0.035), overall in 23%. The larger the volume encompassed by the reference isodose, the more late (p = 0.004) mucosal reactions were observed. Conclusion: PDR BT continued over a few days is a feasible and safe approach in head-and-neck tumors; however, it is accompanied by some toxicity. Dental care should precede isotope application.

    Tobacco smoking is one of the major risk factors in pathogenesis of head and neck squamous cell carcinomas (HNSCC). Many of the chemical compounds present in tobacco are well-known carcinogens which form adducts with DNA. Cells remove these adducts mainly by the nucleotide excision repair pathway (NER). NER also eliminates a broad spectrum of pyrimidine dimers (CPD) and photo-products (6-4PP) induced by UV-radiation or DNA cross-links after cisplatin anti-cancer treatment. In this study DNA damage and repair was examined in peripheral blood lymphocytes obtained from 20 HNSCC patients and 20 healthy controls as well as HTB-43 larynx and SSC-25 tongue cancer cell lines. DNA repair kinetics in the examined cells after cisplatin or UV-radiation treatment were investigated using alkaline comet assay during 240 min of post-treatment incubation. MTT assay was used to analyse cell viability and the Annexin V-FITC kit specific for kinase-3 was employed to determine apoptosis after treating the cells with UV-radiation at dose range from 0.5 to 60 J/m{sup 2}. NER capability was assessed in vitro with cell extracts by the use of a bacterial plasmid irradiated with UV-light as a substrate for the repair. The results show that lymphocytes from HNSCC patients and HTB-43 or SSC-25 cancer cells were more sensitive to genotoxic treatment with UV-radiation and displayed impaired DNA repair. Also evidenced was a higher rate of apoptosis induction after UV-radiation treatment of lymphocytes from the HNSCC patients and the HTB-43 cancer cells than after treatment of those from healthy donors. Finally, our results showed that there was a significant decrease in NER capacity in HTB-43 or SSC-25 cancer cells as well as in peripheral blood lymphocytes of HNSCC patients compared to controls. In conclusion, we suggest that the impaired NER pathway might be a critical factor in pathogenesis of head and neck cancer.

    Full Text Available Head and neck squamous cell carcinoma (HNSCC is a highly lethal cancer. Previously, we identify head and neck cancer initiating cells (HN-CICs, which are highly tumorigenic and resistant to conventional therapy. Therefore, development of drug candidates that effectively target HN-CICs would benefit future head and neck cancer therapy. In this study, we first successfully screened for an active component, named YMGKI-1, from natural products of Antrodia cinnamomea Mycelia (ACM, which can target the stemness properties of HNSCC. Treatment of YMGKI-1 significantly downregulated the aldehyde dehydrogenase (ALDH activity, one of the characteristics of CIC in HNSCC cells. Additionally, the tumorigenic properties of HNSCC cells were attenuated by YMGKI-1 treatment in vivo. Further, the stemness properties of HN-CICs, which are responsible for the malignancy of HNSCC, were also diminished by YMGKI-1 treatment. Strikingly, YMGKI-1 also effectively suppressed the cell viability of HN-CICs but not normal stem cells. Finally, YMGKI-1 induces the cell death of HN-CICs by dysregulating the exaggerated autophagic signaling pathways. Together, our results indicate that YMGKI-1 successfully lessens stemness properties and tumorigenicity of HN-CICs. These findings provide a new drug candidate from purified components of ACM as an alternative therapy for head and neck cancer in the future.

    The management of pulmonary nodules is challenging; unfortunately, little is known about the incidence and significance of pulmonary nodules in patients with head and neck cancer. A review was conducted of 400 consecutive patients with head and neck cancer. Imaging was reviewed to identify the incidence of nodules and patient, tumor, and radiological factors associated with the risk of malignancy. Nodules were found in 58% of patients, with a malignant rate of 6%. Age was the only predictor of having a nodule and advanced-stage III + IV was a predictor of malignancy (P = .023; odds ratio [OR] 10.64; confidence interval 1.33-84.98). Patients presenting with head and neck cancer have a higher incidence of pulmonary nodules and a higher risk of malignancy. In contrast to the British Thoracic Society (BTS) guidelines, which use size to guide the need for serial scans, we would recommend follow-up imaging in all patients with head and neck cancer with nodules, irrespective of size. © 2017 Wiley Periodicals, Inc.

    Purpose To explore the prognostic value of metabolic tumor volume measured on post-radiation 18F-fluorodeoxyglucose positron emission tomography (PET) imaging in head-and-neck cancer patients. Methods and Materials Forty-seven head-and-neck cancer patients who received pre- and post-treatment PET/CT imaging along with definitive chemoradiotherapy were included in this study. PET/CT parameters evaluated include the maximum standardized uptake value, metabolic tumor volume (MTV2.0-MTV4.0; where MTV2.0 refers to the volume above an SUV threshold of 2.0), and integrated tumor volume. Kaplan-Meier and Cox-regression models were used to test for association between PET endpoints and disease-free survival (DFS) and overall survival (OS). Results Multiple post-radiation PET endpoints correlated significantly with outcome, however the most robust predictor of disease progression and death was MTV2.0. An increase in MTV2.0 of 21cm3 (difference between 75th and 25th percentile) was associated with an increased risk of disease progression (hazard ratio [HR]=2.5, p=0.0001) and death (HR=2.0, p=0.003). In patients with non-nasopharyngeal carcinoma (non-NPC) histology (n=34), MTV2.0<18cm3 and MTV2.0≥18cm3 yielded 2-year DFS rates of 100% and 63%, respectively (p=0.006) and 2-year OS rates of 100% and 81%, respectively (p=0.009). There was no correlation between MTV2.0 and DFS or OS with NPC histology (n=13). On multivariate analysis only post-radiation MTV2.0 was predictive of DFS (HR=2.47, p=0.0001) and OS (HR=1.98, p=0.003). Conclusions Post-radiation metabolic tumor volume is an adverse prognostic factor in head-and-neck cancer. Biomarkers such as MTV are important for risk stratification, and will be valuable in the future with risk-adapted therapies. PMID:20646870

  2. The role of head and neck squamous cell carcinoma cancer stem cells in tumorigenesis, metastasis, and treatment failure

    2012-01-01

    Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide. Despite advances in diagnostic and therapeutic methods, survival of HNSCC remains unchanged over the last 30 years with treatment failure and metastases being the strongest indicators of poor outcome. Cancer stem cells (CSC) have been identified in multiple other solid tumors, including breast, prostate, and pancreatic carcinoma. Recently, a subpopulation of tumor cells has been identified in HNSCC based ...

    The purpose of this study is to evaluate the effect of arterial input selection on perfusion CT parameters of head and neck tumors. Perfusion calculations were done for 50 cases using deconvolution-based software. Peak enhancement values of the ipsilateral internal carotid artery (ICA) and external carotid artery (ECA) were recorded. Blood flow (BF), blood volume (BV), mean transit time (MTT), and permeability surface area product were calculated using ipsilateral ECA, ipsilateral ICA, and contralateral ICA as input arteries. Values were compared using Wilcoxon's matched pair test and Pearson's correlation coefficients (r). A highly significant correlation was observed between peak enhancement values of the ICA and ECA (r = 0.97; p 0.05). Arterial input selection has no significant effect on perfusion CT calculation of head and neck cancer. For standardization and simplification of postprocessing, we recommend the use of the ICA instead of the ECA as the arterial input because of its better visualization, perpendicular course, and larger caliber, all of which decrease partial volume effects.

    Purpose: The purpose of this study was to examine factors associated with the presence of secondary external and internal lymphedema in patients with head-and-neck cancer (HNC). Methods and Materials: The sample included 81 patients {>=}3 months after HNC treatment. Physical and endoscopic examinations were conducted to determine if participants had external, internal, and/or combined head-and-neck lymphedema. Logistic regression analysis was used to examine the factors associated with the presence of lymphedema. Results: The following factors were statistically significantly associated with presence of lymphedema: (1) location of tumor associated with presence of external (P=.009) and combined lymphedema (P=.032); (2) time since end of HNC treatment associated with presence of external (P=.004) and combined lymphedema (P=.005); (3) total dosage of radiation therapy (P=.010) and days of radiation (P=.017) associated with the presence of combined lymphedema; (4) radiation status of surgical bed was associated with the presence of internal lymphedema, including surgery with postoperative radiation (P=.030) and (salvage) surgery in the irradiated field (P=.008); and (5) number of treatment modalities associated with external (P=.002), internal (P=.039), and combined lymphedema (P=.004). No demographic, health behavior-related, or comorbidity factors were associated with the presence of lymphedema in the sample. Conclusions: Select tumor and treatment parameters are associated with increased occurrence of lymphedema in patients with HNC. Larger and longitudinal studies are needed to identify adjusted effects and causative risk factors contributing to the development of lymphedema in patients with HNC.

    We retrospectively analyzed 54 patients who died of head and neck squamous cell caricinoma regarding the process and duration of cachexia using the modified Glasgow Prognostic Score (mGPS). The patients were classified as having cachexia when the serum albumin level was less than 3.5 mg/dL and the C-reactive protein (CRP) level was more than 0.5 mg/dL. The number of patients with cachexia was eight (8%) at the first visit and 50 (93%) at the time of death. In the 50 patients, the median and average time of having cachexia was 59 and 95 days, respectively. Thirty-two of the 50 patients (64%) died within three months after the presence of cachexia was confirmed. In this study, the time of having cachexia was so short, then the policy of care should be converted from aggressive into supportive in patients classified as having cachexia. mGPS would be an accurate assessment tool for cachexia and ascertain the end stage of head and neck cancer patients.

    Low-grade extraskeletal osteosarcoma is a rare tumor that may arise de novo or following radiation therapy. Because of the low-grade histology, it may be misdiagnosed as a benign lesion. We present a case of a 59-year-old man with a past history of radiotherapy for papillary carcinoma of the thyroid, presenting 16 years later with a low-grade extraskeletal osteosarcoma of the neck. The patient was treated with surgical excision and is disease free after 12 months of follow-up. The prognosis for patients with low-grade extraskeletal osteosarcoma is relatively good when compared with high-grade sarcomas. While there is a report of a low-grade extraskeletal osteosarcoma arising following radiotherapy for a benign condition, to the best of our knowledge this is the first reported case of a low-grade extraskeletal osteosarcoma occurring following radiotherapy for thyroid cancer, and the only case reported in the soft tissue of the head and neck region. © The Author(s) 2015.

    Full Text Available Objective. To elucidate the incidence of cisplatin induced ototoxicity in adult patients, with a focus on an adult population. Study Design. IRB approved retrospective study. Methods. The charts of patients who underwent cisplatin therapy from 1995 to present were reviewed. Inclusion criteria were (1 cisplatin as the primary chemotherapeutic agent and (2 hearing evaluation performed prior to and after treatment. Audiometric thresholds were measured by presenting pure-tone stimuli at 0.25 to 10.0 kHz. Criteria for hearing loss were based on the Chang criteria. Cochlear radiation doses were also calculated in patients with primary tumors in their head and neck or brain. Results. There were 1565 patients that had undergone therapy with cisplatin from 1995 to 2014, which 30 met inclusion criteria. Eight were patients treated for head and neck or brain cancer. Evaluation with ANOVA testing identified statistically significant decline in audiometric scores for WRS and pure tone frequencies 500, 2000, 4000, 6000, and 8000 Hz in the right ear. Overall, hearing loss was noted with 63% incidence and in patients who received radiation to their cochlea and cisplatin. Conclusion. The incidence of cisplatin induced ototoxicity was significant and even more prevalent in those patients receiving both cisplatin and radiation to their cochlea.

    Full Text Available Human papillomavirus (HPV was recently recognized as a new risk factor for head and neck squamous cell carcinoma. For oropharyngeal cancers, an HPV+ status is associated with better prognosis in a subgroup of nonsmokers and nondrinkers. However, HPV infection is also involved in the biology of head and neck carcinoma (HNC in patients with a history of tobacco use and/or alcohol consumption. Thus, the involvement of HPV infection in HN carcinogenesis remains unclear, and further studies are needed to identify and analyze HPV-specific pathways that are involved in this process. Using a quantitative proteomics-based approach, we compared the protein expression profiles of two HPV+ HNC cell lines and one HPV− HNC cell line. We identified 155 proteins that are differentially expressed (P<0.01 in these three lines. Among the identified proteins, prostate stem cell antigen (PSCA was upregulated and eukaryotic elongation factor 1 alpha (EEF1α was downregulated in the HPV+ cell lines. Immunofluorescence and western blotting analyses confirmed these results. Moreover, PSCA and EEF1α were differentially expressed in two clinical series of 50 HPV+ and 50 HPV− oral cavity carcinomas. Thus, our study reveals for the first time that PSCA and EEF1α are associated with the HPV-status, suggesting that these proteins could be involved in HPV-associated carcinogenesis.

    HSP-90 is an intracellular protein that protects the cell from environmental stress situations. The overexpression of HSP-90 isoforms could serve as a mechanism of resistance to radiotherapy for tumour cells. We studied this effect in a sample of head and neck tumours. We included 87 patients diagnosed with oral cavity, oropharynx, larynx and hypopharynx tumours. We studied the expression of the HSP-90 isoforms by real-time PCR on pre-treatment biopsy samples. We analysed the relationship between HSP-90 expression levels and local relapse of the tumour with CRT decision trees. The expression levels of the inducible citosolic isoform (HSP90AA) allowed the definition of 2 groups of patients with different rates of local relapse. The group with a low expression level showed a 2.9% local relapse rate, while the group with a high expression level showed a 38.2% rate. Survival curves showed differences in time to local relapse for both groups of patients. These differences did not reach statistical significance. Radiotherapy response was related to expression levels of HSP-90 in a sample of head and neck cancer patients. This result could prove useful in the selection of treatments for this group of patients.

    Until now, there is no optimal technique for repairing oronasal fistula in patients with prior head and neck radiotherapy and trismus. Use of the silicone button is a safe, office-based, and validated method in this situation. The indications of this procedure are also clarified in this study. This is a retrospective study of four patients who underwent a newly designed endoscopic repair of oronasal fistula with silicone button under local anesthesia from July 2012 to August 2012. Data on the size of the defect, length of operation, symptom relief, and post-operative complications were collected. Four patients underwent endoscopic repair of oronasal fistula with silicone button under local anesthesia. The diagnoses were benign palate lesion s/p operation, oral cancer s/p operation and radiotherapy. The defect diameter varied from 1 to 1.5 cm. The operation durations were between 20 and 30 min. In all cases, nasal regurgitation symptoms were relieved. The hypernasality of one case improved, while another had decreased nasal crusting and foul odors. No major complications were noted. There was a minor complication in one case, which exhibited frequent crusting around the silicone button. Silicon button can act as a temporary obturator to improve quality of life of patients. The indications for this procedure include patient undergone head and neck radiotherapy with (1) chronic fistula (>6 months); (2) small defect (1-2 cm); and (3) trismus. 4.

    2010-02-01

    Full Text Available Vascular endothelial growth factor (VEGF is one of the most potent endothelial cell mitogens and plays a critical role in angiogenesis. Polymorphisms in this gene have been evaluated in patients with several types of cancer. The objectives of this study were to determine if there was an association of the -1154G/A polymorphism of the VEGF gene with head and neck cancer and the interaction of this polymorphism with lifestyle and demographic factors. Additionally, the distribution of the VEGF genotype was investigated with respect to the clinicopathological features of head and neck cancer patients. The study included 100 patients with histopathological diagnosis of head and neck squamous cell carcinoma. Patients with treated tumors were excluded. A total of 176 individuals 40 years or older were included in the control group and individuals with a family history of neoplasias were excluded. Analysis was performed after extraction of genomic DNA using the real-time PCR technique. No statistically significant differences between allelic and genotype frequencies of -1154G/A VEGF polymorphism were identified between healthy individuals and patients. The real-time PCR analyses showed a G allele frequency of 0.72 and 0.74 for patients and the control group, respectively. The A allele showed a frequency of 0.28 for head and neck cancer patients and 0.26 for the control group. However, analysis of the clinicopathological features showed a decreased frequency of the A allele polymorphism in patients with advanced (T3 and T4 tumors (OR = 0.36; 95%CI = 0.14-0.93; P = 0.0345. The -1154A allele of the VEGF gene may decrease the risk of tumor growth and be a possible biomarker for head and neck cancer. This polymorphism is associated with increased VEGF production and may have a prognostic importance.

  16. The STAT3 pathway as a therapeutic target in head and neck cancer: Barriers and innovations.

    2016-05-01

    Proteins of the signal transducer and activator of transcription (STAT) family mediate cellular responses to cytokines and growth factors. Aberrant regulation of the STAT3 oncogene contributes to tumor formation and progression in many cancers, including head and neck squamous cell carcinoma (HNSCC), where hyperactivation of STAT3 is implicated in both treatment resistance and immune escape. There are no oncogenic gain-of-function mutations in HNSCC. Rather, aberrant STAT3 signaling is primarily driven by upstream growth factor receptors, such as Janus kinase (JAK) and epidermal growth factor receptor (EGFR). Moreover, genomic silencing of select protein tyrosine phosphatase receptors (PTPRs), tumor suppressors that dephosphorylate STAT3, may lead to prolonged phosphorylation and activation of STAT3. This review will summarize current knowledge of the STAT3 pathway and its contribution to HNSCC growth, survival, and resistance to standard therapies, and discuss STAT3-targeting agents in various phases of clinical development.

    Dean, Jamie A; Harrington, Kevin J; Nutting, Christopher M; Gulliford, Sarah L

    2014-01-01

    In radiotherapy for head and neck cancer, the radiation dose delivered to the pharyngeal mucosa (mucosal lining of the throat) is thought to be a major contributing factor to dysphagia (swallowing dysfunction), the most commonly reported severe toxicity. There is a variation in the severity of dysphagia experienced by patients. Understanding the role of the dose distribution in dysphagia would allow improvements in the radiotherapy technique to be explored. The 3D dose distributions delivered to the pharyngeal mucosa of 249 patients treated as part of clinical trials were reconstructed. Pydicom was used to extract DICOM (digital imaging and communications in medicine) data (the standard file formats for medical imaging and radiotherapy data). NumPy and SciPy were used to manipulate the data to generate 3D maps of the dose distribution delivered to the pharyngeal mucosa and calculate metrics describing the dose distribution. Multivariate predictive modelling of severe dysphagia, including descriptions of the d...

    2016-01-01

    A major problem in the treatment of head and neck cancer today is the resistance of tumors to traditional radiation therapy, which results in 40% local failure, despite aggressive treatment. The main objective of this study was to develop a technique which will overcome tumor radioresistance by increasing the radiation absorbed in the tumor using cetuximab targeted gold nanoparticles (GNPs), in clinically relevant energies and radiation dosage. In addition, we have investigated the biological mechanisms underlying tumor shrinkage and the in vivo toxicity of GNP. The results showed that targeted GNP enhanced the radiation effect and had a significant impact on tumor growth (P < 0.001). The mechanism of radiation enhancement was found to be related to earlier and greater apoptosis (TUNEL assay), angiogenesis inhibition (by CD34 level) and diminished repair mechanism (PCNA staining). Additionally, GNPs have been proven to be safe as no evidence of toxicity has been observed.

    2012-01-01

    There is no standardized dysphagia therapy for head and neck cancer patients and scant evidence to support any particular protocol, leaving institutions and individual speech language pathologists (SLPs) to determine their own protocols based on “typical” practices or anecdotal evidence. To gain an understanding of current usual practices, a national internet-based survey was developed and disseminated to SLPs who treat HNC patients. From a random sample of 4,000 ASHA SID 13 members, 1,931 fit the inclusion criteria, and 759 complete responses were recorded for a 39.3% response rate. Results were analyzed by institution type as well as by individual clinical experience. While some interesting trends emerged from the data, a lack of uniformity and consensus regarding best practices was apparent. This is undoubtedly due to a paucity of research adequately addressing the efficacy of any one therapy for dysphagia in the HNC population. PMID:22456699

    The recent emergence of a clinically distinct subset of head and neck cancers (HNC) caused by infection with the human papillomavirus (HPV) necessitates critical reevaluation of the existing counseling paradigm for patients with newly diagnosed HNC. Herein we propose a structural framework for patient counseling in which HPV testing is incorporated and the impact of HPV-status is discussed in the context of multiple medical and psychosocial domains. We strive to maintain a balance between making recommendations based on the best available scientific evidence and acknowledgment of uncertainty for both patients and providers. We anticipate that both the standard-of-care diagnostic workup and treatment, and counseling guidelines for these patients will change rapidly in the years ahead, as data from ongoing and planned prospective clinical trials become available.

    Full Text Available Most of the current radiation therapy planning systems, which are based on pre-treatment Computer Tomography (CT images, assume that the tumor geometry does not change during the course of treatment. However, tumor geometry is shown to be changing over time. We propose a methodology to monitor and predict daily size changes of head and neck cancer tumors during the entire radiation therapy period. Using collected patients' CT scan data, MATLAB routines are developed to quantify the progressive geometric changes occurring in patients during radiation therapy. Regression analysis is implemented to develop predictive models for tumor size changes through entire period. The generated models are validated using leave-one-out cross validation. The proposed method will increase the accuracy of therapy and improve patient's safety and quality of life by reducing the number of harmful unnecessary CT scans.

    Full Text Available The use of PET/CT as an adjunct in radiotherapy planning is an attractive option in head and neck cancer (HNC for several reasons. First, with potentially better identification of the disease extent i.e. staging, the risk of geographical miss of radiation delivery to the gross tumour volume (GTV is reduced. Second, in characterising the biological behaviour of the disease for example, areas of hypoxia, rich or poor vascularity or high cell proliferation, PET/CT can identify biological target volumes (BTVs either for escalation of radiation dose or to predict the requirement for the addition of a radiosensitiser or alternative treatment strategies. 18F-FDG is the most common tracer used in oncology studies, but many other tracers have been investigated with several entering clinical practice, although these remain predominantly in the research domain in HNC. These issues will be discussed in this review.

    The role of art in medicine is complex, varied and uncertain. To examine one aspect of the relationship between art and medicine, investigators analysed the interactions between a professional artist and five adult patients with head and neck cancer as they cocreated portraits in a clinical setting. The artist and four members of an interdisciplinary team analysed the portraits as well as journal entries, transcripts of portrait sessions and semistructured interviews. Over the course of 5 months, 24 artworks evolved from sittings that allowed both the patients and the artist to collaborate around stories of illness, suffering and recovery. Using narrative inquiry and qualitative arts-based research techniques five emergent themes were identified: embracing uncertainties; developing trusting relationships; engaging in reflective practices; creating shared stories; and empowerment. Similar themes are found in successful physician-patient relationships. This paper will discuss these findings and potential implications for healthcare and medical education.

    Concurrent chemoradiation (CCR) therapy is a standard treatment for patients with locally advanced head and neck cancer (HNC). It is well documented that CCR causes profound acute and late toxicities. Xerostomia (the symptom of dry mouth) and hyposalivation (decreased salivary flow) are among the most common treatment side effects in this cohort of patients during and following treatment. They are the result of radiation-induced damage to the salivary glands. Patients with chronic hyposalivation are at risk for demineralization and dental cavitation (dental caries), often presenting as a severe form of rapidly developing decay that results in loss of dentition. Usual post-radiation oral care which includes the use of fluoride, may decrease, but does not eliminate dental caries associated with radiation-induced hyposalivation. The authors conducted a narrative literature review regarding dental caries in HNC population based on MEDLINE, PubMed, CLNAHL, Cochrane database, EMBASE, and PsycINFO from 1985 to 2014. Primary search terms included head and/or neck cancer, dental caries, dental decay, risk factor, physical symptom, physical sequellea, body image, quality of life, measurement, assessment, cost, prevention, and treatment. The authors also reviewed information from National Institute of Dental and Craniofacial Research (NIDCR), American Dental Association (ADA), and other related healthcare professional association web sites. This literature review focuses on critical issues related to dental caries in patients with HNC: potential mechanisms and contributing factors, clinical assessment, physical sequellea, negative impact on body image and quality of life, potential preventative strategies, and recommendations for practice and research in this area.

    To assess clinical success and safety of endoscopic pharyngoesophageal dilation after chemoradiation or radiation for head and neck cancer and to identify variables associated with dilation failure. Case series with chart review. Between 2000 and 2008, a total of 111 patients treated with chemoradiation or radiation for head and neck cancer with subsequent pharyngoesophageal stenosis requiring endoscopic dilation were identified. Patients were evaluated for endoscopic dilation technique, severity of stenosis, technical and clinical success, and intra- and postoperative complications. The Diet/GT score (range, 1-5) was utilized to measure swallow success. Variables associated with dilation failure were analyzed by univariate and multivariate logistic regression. There were 271 dilations analyzed, with 42 combined antegrade retrograde dilations, 208 dilations over a guidewire, and 21 dilations without guidewire. Intraoperative patency and successful dilation of the stenotic segment was achieved in 95% of patients. A Diet/GT score of 5 (gastrostomy tube removed and soft/regular diet) was attained in 84 of 111 (76%) patients. Safety analysis showed complications occurred in 9% of all dilations. Perforations were noted in 4% of all procedures, with only two esophageal perforations requiring significant intervention. Multiple dilations were associated with an increased risk for perforations. Further logistic regression analyses revealed that the number of dilations was indicating a poor outcome and low Diet/GT score. Pharyngoesophageal stenosis, occurring after chemoradiation and radiation treatment, can be successfully and safely treated with endoscopic dilation techniques. Patients with restenosis, requiring multiple dilations, have a higher risk of persistent dysphagia. Copyright © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

    Prognostic factors (e.g., gender, tumor stage, and hypoxia) have an impact on survival in patients with head and neck cancer. Thus, the impact of physical status and comorbidities on treatment decision and survival were evaluated. A total of 169 primary, inoperable patients with squamous cell cancer of the head and neck were retrospectively investigated. Patients were treated with hyperfractionated accelerated radio(chemo)therapy (HARcT) or hypofractionated radio(chemo)therapy (HypoRcT). Depending on the individual patient's situation (Karnofsky Performance Index, KPI), treatment for patients with a KPI of 80-100% was generally radiochemotherapy and for patients with a KPI ≤ 70% treatment was radiotherapy alone. In addition, all comorbidities were evaluated. Uni- and multivariate proportional hazards model were used, and overall survival (OS) was estimated by the Kaplan-Meier method. Treatment consisted of HARcT for 76 patients (45%), HART for 28 patients (17%), HypoRcT for 14 patients(8%), and HypoRT for 51 patients (30%). Of the patients, 107 patients (63%) presented with a KPI of 80-100%. OS (20%) was significantly better for patients with a KPI of 80-100%, while the OS for patients with a KPI ≤ 70% was 8% (p KPI, total irradiation dose (> 70 Gy), and chemotherapy were significant prognostic factors for better OS. Our retrospective analysis shows that performance status with dependency on comorbidities was an independent risk factor for OS.

  12. Nisin ZP, a Bacteriocin and Food Preservative, Inhibits Head and Neck Cancer Tumorigenesis and Prolongs Survival.

    Full Text Available The use of small antimicrobial peptides or bacteriocins, like nisin, to treat cancer is a new approach that holds great promise. Nisin exemplifies this new approach because it has been used safely in humans for many years as a food preservative, and recent laboratory studies support its anti-tumor potential in head and neck cancer. Previously, we showed that nisin (2.5%, low content has antitumor potential in head and neck squamous cell carcinoma (HNSCC in vitro and in vivo. The current studies explored a naturally occurring variant of nisin (nisin ZP; 95%, high content for its antitumor effects in vitro and in vivo. Nisin ZP induced the greatest level of apoptosis in HNSCC cells compared to low content nisin. HNSCC cells treated with increasing concentrations of nisin ZP exhibited increasing levels of apoptosis and decreasing levels of cell proliferation, clonogenic capacity, and sphere formation. Nisin ZP induced apoptosis through a calpain-dependent pathway in HNSCC cells but not in human oral keratinocytes. Nisin ZP also induced apoptosis dose-dependently in human umbilical vein endothelial cells (HUVEC with concomitant decreases in vascular sprout formation in vitro and reduced intratumoral microvessel density in vivo. Nisin ZP reduced tumorigenesis in vivo and long-term treatment with nisin ZP extended survival. In addition, nisin treated mice exhibited normal organ histology with no evidence of inflammation, fibrosis or necrosis. In summary, nisin ZP exhibits greater antitumor effects than low content nisin, and thus has the potential to serve as a novel therapeutic for HNSCC.

    Eighteen patients with 25 unresectable advanced or recurrent head and neck cancers (squamous cell carcinomas) received thermochemotherapy in combination with radiotherapy. The total radiation dose ranged from 50 to 82 Gy (mean, 65.6 Gy). Patients received thermochemotherapy twice a week, for a total number of 8.8 sessions, on average. The temperature in the tumor, as a result of the hyperthermia, was over 42 deg C in 185 (84.5%) of the 219 treatments. Three kinds of heating systems were used: a 13.56-MHz radiofrequency system, a 2450-MHz microwave system, and a radiofrequency interstitial system. The total amount of administered CDDP ranged from 40 to 300 mg (mean, 110 mg), combined with PEP and/or 5FU. Background factors (tumor factors and treatment factors) were investigated in detail, and the clinical results (tumor response and the 5-year cumulative focal control rate) were evaluated. The relationship between these two results was then analyzed using univariate and multivariate statistics. The clinical results of patients with a WHO histological classification of grade 3 were poor compared with patients with a classification of grade 1 or 2. The difference between these two results was significant when analyzed using univariate statistics, but not significant when analyzed using multivariate statistics. The clinical results of patients with primary lesions surrounded by bony tissues were slightly poor compared with those of patients whose lesions were surrounded by soft tissues, but the difference between these two results was not significant. Successful treatment of refractory recurrent tumors, large tumor masses, and diffuse invasive carcinomas was not affected by the treatment factors (heating systems, heating sessions, radiation dose, and CDDP dose and drug combination). These results suggest that refractory recurrence, proximity to bony tissues, tumor size, and histological malignancy might not be prognostic variables for thermochemoradiotherapy strategy

    To propose a novel measure, namely the 'asphericity' (ASP), of spatial irregularity of FDG uptake in the primary tumour as a prognostic marker in head-and-neck cancer. PET/CT was performed in 52 patients (first presentation, n = 36; recurrence, n = 16). The primary tumour was segmented based on thresholding at the volume-reproducible intensity threshold after subtraction of the local background. ASP was used to characterise the deviation of the tumour's shape from sphere symmetry. Tumour stage, tumour localisation, lymph node metastases, distant metastases, SUV{sub max}, SUV{sub mean}, metabolic tumour volume (MTV) and total lesion glycolysis (TLG) were also considered. The association of overall (OAS) and progression-free survival (PFS) with these parameters was analysed. Cox regression revealed high SUV{sub max} [hazard ratio (HR) = 4.4/7.4], MTV (HR = 4.6/5.7), TLG (HR = 4.8/8.9) and ASP (HR = 7.8/7.4) as significant predictors with respect to PFS/OAS in case of first tumour manifestation. The combination of high MTV and ASP showed very high HRs of 22.7 for PFS and 13.2 for OAS. In case of recurrence, MTV (HR = 3.7) and the combination of MTV/ASP (HR = 4.2) were significant predictors of PFS. ASP of pretherapeutic FDG uptake in the primary tumour improves the prediction of tumour progression in head-and-neck cancer at first tumour presentation. (orig.)

    Radiation therapy is often used as the preferred clinical treatment for control of localized head and neck cancer. However, during the course of treatment (6-8 weeks), feedback about functional and/or physiological changes within impacted tissue are not obtained, given the onerous financial and/or logistical burdens of scheduling MRI, PET or CT scans. Diffuse optical sensing is well suited to address this problem since the instrumentation can be made low-cost and portable while still being able to non-invasively provide information about vascular oxygenation in vivo. Here we report results from studies that employed an optical fiber-based portable diffuse reflectance spectroscopy (DRS) system to longitudinally monitor changes in tumor vasculature within two head and neck cancer cell lines (SCC-15 and FaDu) xenografted in the flanks of nude mice, in two separate experiments. Once the tumor volumes were 100mm3, 67% of animals received localized (electron beam) radiation therapy in five fractions (8Gy/day, for 5 days) while 33% of the animals served as controls. DRS measurements were obtained from each animal on each day of treatment and then for two weeks post-treatment. Reflectance spectra were parametrized to extract total hemoglobin concentration and blood oxygen-saturation and the resulting time-trends of optical parameters appear to be dissimilar for the two cell-lines. These findings are also compared to previous animal experiments (using the FaDu line) that were irradiated using a photon beam radiotherapy protocol. These results and implications for the use of fiber-based DRS measurements made at local (irradiated) tumor site as a basis for identifying early radiotherapy-response are presented and discussed.

  16. Cisplatin Induces Bmi-1 and Enhances the Stem Cell Fraction in Head and Neck Cancer

    Full Text Available Recent evidence has unveiled a subpopulation of highly tumorigenic, multipotent cells capable of self-renewal in head and neck squamous cell carcinomas (HNSCCs. These unique cells, named here cancer stem cells (CSCs, proliferate slowly and might be involved in resistance to conventional chemotherapy. We have shown that CSCs are found in perivascular niches and rely on endothelial cell-secreted factors [particularly interleukin-6 (IL-6] for their survival and self-renewal in HNSCC. Here, we hypothesized that cisplatin enhances the stem cell fraction in HNSCC. To address this hypothesis, we generated xenograft HNSCC tumors with University of Michigan-squamous cell carcinoma 22B (UM-SCC-22B cells and observed that cisplatin treatment increased (P = .0013 the fraction of CSCs [i.e., aldehyde dehydrogenase activity high and cluster of differentiation 44 high (ALDHhighCD44high]. Cisplatin promoted self-renewal and survival of CSCs in vitro, as seen by an increase in the number of orospheres in ultralow attachment plates and induction in B lymphoma Mo-MLV insertion region 1 homolog (Bmi-1 and octamer-binding transcription factor 4 expression. Cisplatin-resistant cells expressed more Bmi-1 than cisplatinsensitive cells. IL-6 potentiated cisplatin-induced orosphere formation generated when primary human HNSCC cells were sorted for ALDHhighCD44high immediately after surgery and plated onto ultralow attachment plates. IL-6-induced signal transducer and activator of transcription 3 (STAT3 phosphorylation (indicative of stemness was unaffected by treatment with cisplatin in UM-SCC-22B cells, whereas IL-6-induced extracellular signal-regulated kinase (ERK phosphorylation (indicative of differentiation processes was partially inhibited by cisplatin. Notably, cisplatin-induced Bmi-1 was inhibited by interleukin-6 receptor blockade in parental and cisplatin-resistant cells. Taken together, these results demonstrate that cisplatin enhances the fraction of CSCs

    The objective was to investigate the feasibility of using buccal iontophoresis for the simultaneous delivery of chemotherapeutic agents with a view to developing a new approach to treat head and neck cancers. Short duration cathodal iontophoresis of 5-fluorouracil (5-FU; 20mM) and leucovorin (LV; 10 mM) at 1 mA/cm(2) for 10 or 20 min from aqueous solution and a 2% hydroxyethyl cellulose gel at pH 7.6 was evaluated using bovine mucosa in vitro. Iontophoresis resulted in a statistically significant increase in the mucosal deposition of both drugs as compared to passive diffusion (Student's t-test, α=0.05); in each case, drug delivery was selective for deposition with no permeation being observed. After 20 min of iontophoresis, there was an ~ 8-fold enhancement for 5-FU (1.46 ± 0.86 and 11.93 ± 3.81 μg/cm(2), respectively) and a 3-fold increase for LV (8.31 ± 2.44 and 25.08 ± 6.89 μg/cm(2), respectively) when using aqueous solutions. The same trend was observed when the gel was applied for 10 min; passive delivery of 5-FU from the gel resulted in non-detectable levels in the mucosa, while 4.62 ± 1.76 μg/cm(2) were deposited in the mucosa following iontophoresis. Similarly, iontophoretic delivery of LV from the gel resulted in ~ 3-fold higher deposition as compared to passive diffusion (6.71 ± 1.36 and 21.12 ± 9.94 μg/cm(2), respectively). No drug permeation was observed in either case. In conclusion, iontophoresis can be used for targeted topical delivery of chemotherapeutics to the buccal mucosa and may enable less invasive local therapy of head and neck cancers.

    Saliva, a biological fluid, is a promising candidate for novel approaches to prognosis, clinical diagnosis, monitoring and management of patients with both oral and systemic diseases. However, to date, saliva has not been widely investigated as a biomarker for radiation exposure. Since white blood cells are also present in saliva, it should theoretically be possible to investigate the transcriptional biomarkers of radiation exposure classically studied in whole blood. Therefore, we collected whole blood and saliva samples from eight head and neck cancer patients before the start of radiation treatment, at mid-treatment and after treatment. We then used a panel of five genes: BAX, BBC3, CDKN1A, DDB2 and MDM2, designated for assessing radiation dose in whole blood to evaluate gene expression changes that can occur during radiotherapy. The results revealed that the expression of the five genes did not change in whole blood. However, in saliva, CDKN1A and DDB2 were significantly overexpressed at the end, compared to the start, of radiotherapy, and MDM2 was significantly underexpressed between mid-treatment and at the end of treatment. Interestingly, CDKN1A and DDB2 expressions also showed an increasing monotonic relationship with total radiation dose received during radiotherapy. To our knowledge, these results show for the first time the ability to detect gene expression changes in saliva after head and neck cancer radiotherapy, and pave the way for further promising studies validating saliva as a minimally invasive means of biofluid collection to directly measure radiation dose escalation during treatment.

    Purpose: To use Normal Tissue Complication Probability (NTCP) models and comparative planning studies to explore the (cost-)effectiveness of swallowing sparing intensity modulated proton radiotherapy (IMPT) compared with swallowing sparing intensity modulated radiotherapy with photons (IMRT) in head and neck cancer (HNC). Methods and Materials: A Markov model was constructed to examine and compare the costs and quality-adjusted life years (QALYs) of the following strategies: (1) IMPT for all patients; (2) IMRT for all patients; and (3) IMPT if efficient. The assumption of equal survival for IMPT and IMRT in the base case analysis was relaxed in a sensitivity analysis. Results: Intensity modulated proton radiation therapy and IMRT for all patients yielded 6.620 and 6.520 QALYs and cost €50,989 and €41,038, respectively. Intensity modulated proton radiation therapy if efficient yielded 6.563 QALYs and cost €43,650. The incremental cost-effectiveness ratio of IMPT if efficient versus IMRT for all patients was €60,278 per QALY gained. In the sensitivity analysis, IMRT was more effective (0.967 QALYs) and less expensive (€8218) and thus dominated IMPT for all patients. Conclusions: Cost-effectiveness analysis based on normal tissue complication probability models and planning studies proved feasible and informative and enables the analysis of individualized strategies. The increased effectiveness of IMPT does not seem to outweigh the higher costs for all head-and-neck cancer patients. However, when assuming equal survival among both modalities, there seems to be value in identifying those patients for whom IMPT is cost-effective.

    Full Text Available Introduction Radiotherapy or chemoradiotherapy can result in severe swallowing disorders with potential risk for aspiration and can negatively impact the patient's quality of life (QOL. Objective To assess swallowing-related QOL in patients who underwent radiotherapy/chemoradiotherapy for head and neck cancer. Methods We interviewed 110 patients (85 men and 25 women who had undergone exclusive radiotherapy (25.5% or concomitant chemoradiotherapy (74.5% from 6 to 12 months before the study. The Quality of Life in Swallowing Disorders (SWAL-QOL questionnaire was employed to evaluate dysphagia-related QOL. Results The QOL was reduced in all domains for all patients. The scores were worse among men. There was a relationship between oral cavity as the primary cancer site and the fatigue domain and also between advanced cancer stage and the impact of food selection, communication, and social function domains. Chemoradiotherapy association, the presence of nasogastric tube and tracheotomy, and the persistence of alcoholism and smoking had also a negative effect on the QOL. Conclusions According to the SWAL-QOL questionnaire, the dysphagia-related impact on QOL was observed 6 to 12 months after the treatment ended.

    Head and neck cancers (HNCs) are aggressive tumors that typically demonstrate a high glycolytic rate, which results in resistance to cytotoxic therapy and poor prognosis. Due to their location these tumors specifically impair food intake and quality of life, so that prevention of weight loss through nutrition support becomes an important treatment goal. Dietary restriction of carbohydrates (CHOs) and their replacement with fat, mostly in form of a ketogenic diet (KD), have been suggested to accommodate for both the altered tumor cell metabolism and cancer-associated weight loss. In this review, I present three specific rationales for CHO restriction and nutritional ketosis as supportive treatment options for the HNC patient. These are (1) targeting the origin and specific aspects of tumor glycolysis; (2) protecting normal tissue from but sensitizing tumor tissue to radiation- and chemotherapy induced cell kill; (3) supporting body and muscle mass maintenance. While most of these benefits of CHO restriction apply to cancer in general, specific aspects of implementation are discussed in relation to HNC patients. While CHO restriction seems feasible in HNC patients the available evidence indicates that its role may extend beyond fighting malnutrition to fighting HNC itself.

    Full Text Available BACKGROUND: Runt-related transcription factor 3 (RUNX3 is a tumor suppressor of cancer and appears to be an important component of the transforming growth factor-beta (TGF-ss-induced tumor suppression pathway. Surprisingly, we found that RUNX3 expression level in head and neck squamous cell carcinoma (HNSCC tissues, which is one of the most common types of human cancer, was higher than that in normal tissues by a previously published microarray dataset in our preliminary study. Therefore, here we examined the oncogenic role of RUNX3 in HNSCC. PRINCIPAL FINDINGS: Frequent RUNX3 expression and its correlation with malignant behavior were observed in HNSCC. Ectopic RUNX3 overexpression promoted cell growth and inhibited serum starvation-induced apoptosis and chemotherapeutic drug induced apoptosis in HNSCC cells. These findings were confirmed by RUNX3 knockdown. Moreover, RUNX3 overexpression enhanced tumorsphere formation. RUNX3 expression level was well correlated with the methylation status in HNSCC cells. Moreover, RUNX3 expression was low due to the methylation of its promoter in normal oral epithelial cells. CONCLUSIONS/SIGNIFICANCE: Our findings suggest that i RUNX3 has an oncogenic role in HNSCC, ii RUNX3 expression observed in HNSCC may be caused in part by demethylation during cancer development, and iii RUNX3 expression can be a useful marker for predicting malignant behavior and the effect of chemotherapeutic drugs in HNSCC.

    Full Text Available Background/Aims: Head and neck squamous cell carcinoma (HNSCC ranks sixth worldwide for tumor-related mortality. A subpopulation of tumor cells, termed cancer stem cells (CSCs, has the ability to support cancer growth. Therefore, profiling CSC-enriched populations could be a reliable tool to study cancer biology. Methods: We performed phenotypic characterization of 7 HNSCC cell lines and evaluated the presence of CSCs. CSCs from Hep-2 cell line and HNSCC primary cultures were enriched through sphere formation and sphere-forming cells have been characterized both in vitro and in vivo. In addition, we investigated the expression levels of Nicotinamide N-methyltransferase (NNMT, an enzyme overexpressed in several malignancies. Results: CSC markers were markedly expressed in Hep-2 cell line, which was found to be highly tumorigenic. CSC-enriched populations displayed increased expression of CSC markers and a strong capability to form tumors in vivo. We also found an overexpression of CSC markers in tumor formed by CSC-enriched populations. Interestingly, NNMT levels were significantly higher in CSC-enriched populations compared with parental cells. Conclusion: Our study provides an useful procedure for CSC identification and enrichment in HNSCC. Moreover, results obtained seem to suggest that CSCs may represent a promising target for an anticancer therapy.

    Cetuximab is a monoclonal antibody against epidermal growth factor receptor useful in the treatment of patients with Head and Neck Squamous Cell Carcinoma combined with radiotherapy or chemotherapy. Its pharmacokinetics are not influenced by hepatic status and there are no specific warnings concerning its indication in patients with impaired hepatic function. Patients with a previous liver transplant are at risk for hepatic toxicity and use immunosupressants to avoid rejection that can interact with other drugs. We present two cases of patients with a previous liver transplant in which cetuximab was administered to treat head and neck cancer.

    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 {sup 18}F-fluoro-2-deoxyglucose ({sup 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

    The aim of this interview study was to ask patients with head and neck cancer in the Mersey region about their need for financial benefits, the advice they were given about benefits and financial matters, and the financial burden of the disease. Stratified quota sampling was by employment status, whether work had been affected by the cancer, and by sex. Of 51 interviewees (mean (SD) age 61(8) years) 20 were retired, 11 were unemployed, 13 worked full-time, and 7 worked part-time. Cancer had affected the work status of 24. Since diagnosis 57% had suffered financially; this was particularly high in those who had retired (65%), and in those whose work had been affected by cancer (79%). Quality of life had decreased in 53% as a result of the financial impact of the disease. This was most common in the unemployed (64%), and in those whose work was affected by cancer (83%). Only a quarter had been given adequate help and information about finance; this was lowest in the unemployed (18%) and highest in those who were fully employed (39%). One third (17/51) had never claimed benefits. The most common benefits were Disability Living Allowance and Incapacity Benefit. Two-thirds (21/31) had applied for benefits after diagnosis, 18 of these were directly as a result of the disease. The median (IQR) weekly income from benefits was £88 (£60-170). Patients and carers need better access to financial advice. We suggest that each multidisciplinary team should have a designated benefits or financial advisor who is readily available to patients in the clinic and on the ward.

    Poly (ADP-ribose) polymerase inhibitors (PARPi) have shown single agent activity against tumors with deficiencies in the DNA repair mechanism homologous recombination including, but not limited to those harboring BRCA mutations. We hypothesized that, in the context of homologous recombination deficiency (HRD), PARPi could have an effect in head and neck cancer (HNC). We evaluated TCGA data for evidence of HRD using a copy number data signature established for breast cancer. The comparative potency of three PARPi was evaluated using cell viability assays in a panel of HNC cell lines and response was compared to BRCA-deficient breast cancer cell lines. The change in foci formation of γH2AX and RAD51 was assessed with immunofluorescent staining after exposure to a PARPi. Baseline gene expression was analyzed using microarray data. We found a subgroup in the TCGA HNC cohort harboring genomic aberrations consistent with HRD in breast cancer. Rucaparib activity was superior to olaparib and veliparib and showed single agent activity in a subset of HNC cell lines that was comparable to BRCA-deficient breast cancer cell lines. Rucaparib-sensitive and rucaparib-resistant groups showed significant differences in γH2AX and RAD51 foci formation after rucaparib exposure. Expression of genes involved in chromosome structure was strongly associated with rucaparib resistance. We demonstrate that PARPi are effective in a subset of HNC cell lines and propose that HRD may be present in HNC in vivo suggesting that these compounds could play a role in the treatment of HNC.

    Purpose: a retrospective analysis of conservative treatment of anal canal cancers with external radiation therapy and interstitial brachytherapy with or without chemotherapy. Patients and methods: from 1986 to 1996, 69 patients were treated with external radiotherapy (40 Gy/20 fractions) and interstitial brachytherapy (20 Gy) after a mean interval of six weeks for a localized epidermoid carcinoma of the anal canal. Patients who did not complete the whole therapeutic sequence were not included. Forty-five patients received additional 5-fluorouracil- and/or mitomycin C-based chemotherapy regimen. Results: acute toxicity was acceptable. Complete response rate was 81%. Actuarial local control rate was at two and five years, 65% and 59% respectively (median follow-up: eight years). At two, five and ten years, actuarial colostomy rate was 26%, 33% and 33% respectively, and colostomy-free survival rates 61%, 47% and 37%. Overall survival at two, five and ten years was 81%, 65% and 53% respectively. Distant metastases occurred in 11 patients (16%). Prognostic factors for overall survival were performance status (PS) (79% survival at five years for patients with PS 0 versus 50% for patients with PS 1-3, P = 0.04) and tumor stage (80% at five years for T1-T2 versus 53% for T3-T4, P = 0.03). Overall treatment time less than 12 weeks and time interval between external radiotherapy and brachytherapy inferior than six weeks were associated with a better local control (P = 0.05). In multivariate analysis, these prognostic factors were not significant. Conclusion: these results confirm the efficacy of external radiotherapy and brachytherapy in the treatment of small anal canal cancers, and point out the need for improving treatment outcome of larger tumors.

  11. Anti-Tumor Immunity in Head and Neck Cancer: Understanding the Evidence, How Tumors Escape and Immunotherapeutic Approaches

    Directory of Open Access Journals (Sweden)

    Clint T. Allen

    2015-12-01

    Full Text Available Many carcinogen- and human papilloma virus (HPV-associated head and neck cancers (HNSCC display a hematopoietic cell infiltrate indicative of a T-cell inflamed phenotype and an underlying anti-tumor immune response. However, by definition, these tumors have escaped immune elimination and formed a clinically significant malignancy. A number of both genetic and environmental mechanisms may allow such immune escape, including selection of poorly antigenic cancer cell subsets, tumor produced proinflammatory and immunosuppressive cytokines, recruitment of immunosuppressive immune cell subsets into the tumor and expression of checkpoint pathway components that limit T-cell responses. Here, we explore concepts of antigenicity and immunogenicity in solid tumors, summarize the scientific and clinical data that supports the use of immunotherapeutic approaches in patients with head and neck cancer, and discuss immune-based treatment approaches currently in clinical trials.

    In treating head and neck cancer, it is very important to irradiate uniform dose on the junction of the bilateral irradiation field of the upper head and neck and the anterior irradiation field of the lower neck. In order to improve dose distribution on the junction, this study attempted to correct non uniform dose resulting from under dose and over dose using the field-in-field technique in treating the anterior irradiation field of the lower neck and to apply the technique to the treatment of head and neck cancer through comparison with conventional treatment. In order to examine dose difference between the entry point and the exit point where beam diffusion happens in bilateral irradiation on the upper head and neck, we used an anthropomorphic phantom. Computer Tomography was applied to the anthropomorphic phantom, the dose of interest points was compared in radiation treatment planning, and it was corrected by calculating the dose ratio at the junction of the lower neck. Dose distribution on the junction of the irradiated field was determined by placing low-sensitivity film on the junction of the lower neck and measuring dose distribution on the conventional bilateral irradiation of the upper head and neck and on the anterior irradiation of the lower neck. In addition, using the field-in-field technique, which takes into account beam diffusion resulting from the bilateral irradiation of the upper head and neck, we measured difference in dose distribution on the junction in the anterior irradiation of the lower neck. In order to examine the dose at interest points on the junction, we compared and analyzed the change of dose at the interest points on the anthropomorphic phantom using a thermoluminescence dosimeter. In case of dose sum with the bilateral irradiation of the upper head and neck when the field-in-field technique is applied to the junction of the lower neck in radiation treatment planning, The dose of under dose areas increased by 4.7-8.65%.

    Smoking cessation among cancer patients is critical for improving outcomes. Understanding factors associated with smoking abstinence after the diagnosis of cancer can provide direction to develop and test interventions to enhance cessation rates. The purpose of this study was to identify determinants of smoking outcomes among cancer patients. Standardized questionnaires were used to collect data from 163 smokers or recent-quitters (quit≤6 months) at study entry of which 132 and 121 had data collected at 3 and 6 months. Biochemical verification was conducted with urinary cotinine and carbon monoxide. Descriptive statistics, Cronbach alpha coefficients, Pearson correlations, Fisher's exact test, and multivariable logistic regression were used for analyses. Seven-day-point-prevalence-abstinence (PPA) rates were 90/132 (68%) at 3 months; 46/71 (65%) among lung and 44/61 (72%) among head and neck cancer patients, whereas 7-day-PPA rates were 74/121 (61%) at 6 months; 31/58 (53%) among lung and 43/63 (68%) among head and neck cancer patients. Continuous abstinence rates were 63/89 (71%) at 3 months; 32/45 (71%) among lung and 31/44 (70%) among head and neck cancer patients, whereas continuous abstinence rates were 46/89 (52%) at 6 months; 18/45 (40%) among lung and 28/44 (64%) among head and neck cancer patients. Lower cancer-related, psychological and nicotine withdrawal symptoms were associated with increased 7-D-PPA abstinence rates at 3 and 6 months in univariate models. In multivariable models, however, decreased craving was significantly related with 7-day-PPA at 3 months and decreased craving and increased self-efficacy were associated with 7-D-PPA at 6 months. Decreased craving was the only factor associated with continuous abstinence at 6 months. Smoking outcomes among lung and head and neck cancer patients appear to have remained the same over the last two decades despite the availability of an increased number of pharmacotherapy options to treat tobacco

    Lymph nodal involvement is very common in differentiated thyroid cancer, and in addition, cervical lymph node micrometastases are observed in up to 80 % of papillary thyroid cancers. During the last decades, the role of routine central lymph node dissection (RCLD) in the treatment of papillary thyroid cancer (PTC) has been an object of research, and it is now still controversial. Nevertheless, many scientific societies and referral authors have definitely stated that even if in expert hands, RCLD is not associated to higher morbidity; it should be indicated only in selected cases. In order to better analyze the current role of prophylactic neck dissection in the surgical treatment of papillary thyroid cancers, an analysis of the most recent literature data was performed. Prophylactic or therapeutic lymph node dissection, selective, lateral or central lymph node dissection, modified radical neck dissection, and papillary thyroid cancer were used by the authors as keywords performing a PubMed database research. Literature reviews, PTCs large clinical series and the most recent guidelines of different referral endocrine societies, inhering neck dissection for papillary thyroid cancers, were also specifically evaluated. A higher PTC incidence was nowadays reported in differentiated thyroid cancer (DTC) clinical series. In addition, ultrasound guided fine-needle aspiration citology allowed a more precocious diagnosis in the early phases of disease. The role of prophylactic neck dissection in papillary thyroid cancer management remains controversial especially regarding indications, approach, and surgical extension. Even if morbidity rates seem to be similar to those reported after total thyroidectomy alone, RCLD impact on local recurrence and long-term survival is still a matter of research. Nevertheless, only a selective use in high-risk cases is supported by more and more scientific data. In the last years, higher papillary thyroid cancer incidence and more

    In the field of radiotherapy, there is very little scientific data on the management of nonagenarians, especially in patients aged 90 years or more and with head and neck cancer (HNC). We made one of the first retrospective study of the feasibility and safety of radiotherapy in this population with HNC. Records of radiotherapy coming from four health facilities were studied to include all nonagenarian patients with HNC in the last 10 years and who received radiation therapy. We analyzed patient characteristics and primary cancers, as well as objective of the treatment (curative or palliative), efficacy and toxicity. Twenty patients receiving radiotherapy were identified; mean age was 93.2 years (standard deviation 2.8). Treatment was given with curative and palliative intent in 40 and 60 % of cases, respectively. The most common primary tumors were tumors of the salivary glands (30 % of cases), oral cavity tumors (25 % of cases) and thyroid tumors (15 % of cases). Median total prescribed dose was 47.5 Gy (12-70 Gy). Median number of delivered fractions was 18.5 (2-35 fractions). All patients received intensive supportive care during radiotherapy. Toxicities were mild to moderate. Radiotherapy could not be completed for four patients (20 % of cases). One patient developed grade 1-2 delayed toxicities. At the last follow-up, only four patients (20 % of cases) were alive. Cancer was cause of death in most cases. Radiotherapy may be performed for the nonagenarians with HNC. The total dose and fractionation must be adjusted to optimize the tolerance. However, the prognosis remains very poor, cancer being the main cause of death. Research of geriatric vulnerabilities prior to any treatment, in the context of a comprehensive geriatric assessment, is still recommended to select patients for radiotherapy.

    Human papillomavirus (HPV) is a risk factor for head and neck squamous cell carcinoma (HNSCC) as well as esophageal squamous cell carcinoma (ESCC). We aimed to investigate whether HPV infection underlies the field cancerization phenomenon over upper aerodigestive tract to develop synchronous multiple cancers. A case control study. The presence and subtype of HPV-DNA sequence in cancers were examined by polymerase chain reaction and sequencing in a prospective cohort with 100 HNSCCs, 50 of which had synchronous ESCCs. The clinicopathologic characteristics were further analyzed according to the presence of HPV. Twelve patients were HPV-positive, of which 11 were positive for HPV-16. The prevalence of HPV infection were not different between the synchronous and HNSCC alone groups (P = 0.357). Testing for HPV in paired HNSCC and ESCC tissues from the same patient revealed that none were concomitantly HPV-positive. Multivariate logistic regression showed drinking alcohol (odds ratio [OR], 18.75; P = 0.030), alcohol flushing (OR, 2.53; P = 0.041), and body mass index (OR, 0.77; P = 0.001) but not HPV infection were independent risk factors for synchronous phenotype. The patients with synchronous ESCCs had significantly poorer survival than those with HNSCC alone (5-year overall survival: 30% vs. 70%; log-rank P infection plays little role in field cancerization phenomenon to initiate synchronous SCC. The synchronous HNSCC and ESCC from the same patients had no clonal relationship. Routine endoscopic examination of the esophagus should be recommended for patients with risk factors identified. NA.

    Full Text Available Background: In a large and diverse country like India, there is a wide variation in the availability of infrastructure and expertise to treat head-neck cancer patients. Lack of consistent adherence to evidence-based management is the biggest problem. Aims: There is an unmet need to evaluate the existing treatment practices to form the basis for development of effective and uniform treatment policies. Settings and Designs: Prospective case series. Materials and Methods: A group of previously treated, potentially curable patients presenting to our institution (from April 2009 to March 2011 were evaluated for appropriateness of initial treatment based on National Comprehensive Cancer Network or Tata Memorial Hospital guidelines. Data regarding treatment center, protocol and accuracy of delivered treatment and their eventual outcome were analyzed. Statistical Analysis: Descriptive. Results: Amongst 450 newly registered patients, 77(17% were previously treated with curative intent and 69(89% of them were inappropriately treated. Seventeen (25% patients were treated in clinics while 12(17% in cancer centers and 34(50% in corporate hospitals. Fourteen (20% patients received chemotherapy, 22(32% received radiotherapy and 14(20% underwent surgery while 19(28% patients received multimodality treatment. Disease stage changed to more advanced stage in 40(58% patients and curative intent treatment could be offered only to 33(48% patients. Amongst 56 patients available for outcome review, 18(32% patients were alive disease-free, 20(36% had died and 18(32% were alive with disease. Conclusion: Large numbers of potentially curable patients are inappropriately treated and their outcome is significantly affected. Many initiatives have been taken in the existing National Cancer Control Program but formulation of a uniform national treatment guideline should be prioritized.

    Head and neck cancer (HNC) encompasses a diverse group of tumors, and thus providing appropriate and tailored information to patients before, during, and after treatment is a challenge. The objective of the current study was to characterize the experience and unmet needs of patients with HNC with regard to information and support provision. A 28-question, cross-sectional survey was completed by patients treated for HNC at 1 of 4 institutions in New South Wales, Australia (Chris O'Brien Lifehouse and Liverpool, Westmead, and Wollongong hospitals). It consisted of the adapted Kessler Psychological Distress Scale and questions assessing information quality, quantity, and format. A total of 597 patients responded. The mean age of the patients was 58 years (range, 21-94 years) with 284 men and 313 women (1:1.1). The majority of patients reported information concerning the disease process (76%), prognosis (67%), and treatment (77%) was sufficient, and approximately 50% reporting having received little or no information regarding coping with stress and anxiety. A substantial percentage of patients reported receiving minimal information concerning psychosexual health (56%) or the availability of patient support groups (56%). The majority of patients preferred access to multiple modes of information delivery (72%), with the preferred modality being one-on-one meetings with a health educator (37%) followed by internet-based written information (19%). Patients with HNC are a diverse group, with complex educational and support needs. Patients appear to be given information regarding survivorship topics such as psychological well-being, patient support groups, and psychosexual health less frequently than information concerning disease and treatment. Verbal communication needs to be reinforced by accessible, well-constructed, written and multimedia resources appropriate to the patient's educational level.

    To compare simultaneous integrated boost plans for intensity-modulated proton therapy (IMPT), helical tomotherapy (HT), and RapidArc therapy (RA) for patients with head and neck cancer. A total of 20 patients with squamous cell carcinoma of the head and neck received definitive chemoradiation with bilateral (n = 14) or unilateral (n = 6) neck irradiation and were planned using IMPT, HT, and RA with 54.4, 60.8, and 70.4 GyE/Gy in 32 fractions. Dose distributions, coverage, conformity, homogeneity to planning target volumes (PTV)s and sparing of organs at risk and normal tissue were compared. All unilateral and bilateral plans showed excellent PTV coverage and acceptable dose conformity. For unilateral treatment, IMPT delivered substantially lower mean doses to contralateral salivary glands (< 0.001-1.1 Gy) than both rotational techniques did (parotid gland: 6-10 Gy; submandibular gland: 15-20 Gy). Regarding the sparing of classical organs at risk for bilateral treatment, IMPT and HT were similarly excellent and RA was satisfactory. For unilateral neck irradiation, IMPT may minimize the dry mouth risk in this subgroup but showed no advantage over HT for bilateral neck treatment regarding classical organ-at-risk sparing. All methods satisfied modern standards regarding toxicity and excellent target coverage for unilateral and bilateral treatment of head and neck cancer at the planning level. (orig.)

    Epithelial-mesenchymal transition (EMT) is a key process involved in the invasion and metastasis of cancer cells. Furthermore, EMT can induce a cancer stem cell (CSC)-like phenotype in a number of tumor types. We demonstrated that Snail is one of the master regulators that promotes EMT and mediates cancer cell migration and invasion in many types of malignancies including head and neck squamous cell carcinoma (HNSCC). In the present study, we investigated the role of Snail in inducing and maintaining CSC-like properties through EMT in HNSCC. We established HNSCC cell lines transfected with Snail. Stem cell markers were evaluated with real-time RT-PCR and western blot analysis. CSC properties were assessed using sphere formation and WST-8 assays as well as chemosensitivity and chick chorioallantoic membrane in vivo invasion assays. Introduction of Snail induced EMT properties in HNSCC cells. Moreover, Snail-induced EMT maintained the CSC-like phenotype, and enhanced sphere formation capability, chemoresistance and invasive ability. These data suggest that Snail could be one of the critical molecular targets for the development of therapeutic strategies for HNSCC.

They were assessed for psychiatric morbidities using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, fourth edition. Their HRQL was simultaneously evaluated using the quality of life questionnaire of the European Organisation for Research and Treatment of Cancer with a specific module for head and neck cancer; and depressed and nondepressed HNC patients were compared by using the generalized mixed-effect model for repeated measurements.Results: A total of 106 patients were recruited into this study. High rates of anxiety were found at pretreatment, but steadily declined over time (from 27.3% to 6.4%, and later 3.3%. A skew pattern of depression was observed, with prevalence rates from 8.5% at pretreatment to 24.5% and 14% at 3 and 6 months, respectively, after treatment. We found that loss of sense (P=0.001, loss of speech (P<0.001, low libido (P=0.001, dry mouth (P<0.001, and weight loss (P=0.001 were related to depression over time. The depressed patients had a higher consumption of painkillers (P=0.001 and nutrition supplements (P<0.001. The results showed that depression was predicted by sticky saliva (P<0.001 and trouble with

    Full Text Available Oral mucositis (OM is among the most undesirable, painful, and expensive toxicities of cytotoxic cancer therapy, and is disheartening for patients and frustrating for caregivers. Accurate assessment of the incidence of OM has been elusive, but accumulating data suggests that reported OM frequency is significantly less than its actual occurrence. It has been suggested that over 90% of head and neck cancer (HNC patients receiving radiotherapy (RT with concurrent cisplatin experience severe OM with symptoms of extreme pain, mucosal ulceration and consequent limitations in swallowing and achieving adequate nutritional intake. This panoply of symptoms inevitably impacts a patients’ quality of life and their willingness to continue treatment. In spite of all the advances made in understanding the pathophysiology of OM, there is still no prophylactic therapy with proven efficacy. Strategies to limit the extent of OM and to manage its symptomatology include basic oral care, supportive medications, nutritional support and targeting aggressive treatments to high-risk patients. This review focuses on OM recognition, preventive measurements, and symptom-management strategies.

    Full Text Available Cancer radiotherapy (RT induces response of the whole patient’s body that could be detected at the blood level. We aimed to identify changes induced in serum lipidome during RT and characterize their association with doses and volumes of irradiated tissue. Sixty-six patients treated with conformal RT because of head and neck cancer were enrolled in the study. Blood samples were collected before, during and about one month after the end of RT. Lipid extracts were analyzed using MALDI-oa-ToF mass spectrometry in positive ionization mode. The major changes were observed when pre-treatment and within-treatment samples were compared. Levels of several identified phosphatidylcholines, including (PC34, (PC36 and (PC38 variants, and lysophosphatidylcholines, including (LPC16 and (LPC18 variants, were first significantly decreased and then increased in post-treatment samples. Intensities of changes were correlated with doses of radiation received by patients. Of note, such correlations were more frequent when low-to-medium doses of radiation delivered during conformal RT to large volumes of normal tissues were analyzed. Additionally, some radiation-induced changes in serum lipidome were associated with toxicity of the treatment. Obtained results indicated the involvement of choline-related signaling and potential biological importance of exposure to clinically low/medium doses of radiation in patient’s body response to radiation.

    Body weight loss is common in cancer patients, and is often associated with poor prognosis, it greatly impairs quality of life (QOL). Radiation therapy (RT) is used in head and neck cancers (HNC) either as a primary treatment or as an adjuvant therapy to surgery. Patients with HNC are most susceptible to malnutrition especially due to anorexia, which is aggravated by RT. Multiple pro-inflammatory cytokines, such as interleukin-6 (IL-6), interleukin-1beta (IL-1beta), interferon (IFN)-gamma and tumor necrosis factor-alpha(TNF-alpha), have been all associated with the development of both anorexia and oral mucositis. Radiation-induced mucositis occurs in almost all patients, who are treated for HNC, it could also cause weight loss. Ghrelin is a novel 28-amino acid peptide, which up-regulates body weight through appetite control, increase food intake, down-regulate energy expenditure and induces adiposity. Furthermore, ghrelin inhibits pro-inflammatory cytokines such as IL-1alpha, IL-1beta, TNF-alpha which may cause oral mucositis and aneroxia, which are the results of weight loss. Thus weight loss during RT is an early indicator of nutritional decline, we propose that recombinant ghrelin used prophylactically could be useful as an appetite stimulant; and preventive of mucositis because of its anti-inflammatory effect, it might help patients maintain weight over the course of curative RT of the HNC and can improve specific aspects of QOL. This issue warrants further studies.

    Between 1985 and 1990, 99 head and neck cancer patients were treated at Mount Vernon Centre for Cancer Treatment in a CHART pilot study. The aims of this retrospective review were to obtain baseline data for this population on their pretreatment dental status and to determine the extent to which our conservative policy of teeth preservation is being realised. This is of particular interest because of the believed sparing of late normal tissue effects by CHART compared with conventional fractionation. Prior to treatment, 40% of patients were edentulous, and prophylactic dental clearance was avoided in 59% of the remaining (dentate) patients. Following radiotherapy, only 21% of dentate patients subsequently lost all their remaining teeth. The proportion of patients with full or partial upper dentures increased from 61% pretreatment to 76% post-treatment; the corresponding increase in lower dentures was 46% to 66%. However, actual usage of dentures decreased somewhat. There was only one documented case of (minor) osteo-radionecrosis of the mandible which resolved with conservative care. The greater use in our patients of prophylactic measures, in particular, chlorhexidine and fluoride mouthwashes seemed indicated.

    Full Text Available Head and neck squamous cell cancer (HNSCC is one of the top ten cancers in the United States. The survival rate of HNSCC has only marginally improved over the last two decades. In addition, African-American men bear a disproportionate burden of this preventable disease. Therefore, a critical challenge of preventive health approaches is warranted. Salvianolic acid B (Sal-B isolated from Salvia miltiorrhiza Bge, which is a well-know Chinese medicines has been safely used to treat and prevent aging diseases for thousand of years. Recently, the anticancer properties of Sal-B have received more attention. Sal-B significantly inhibits or delays the growth of HNSCC in both cultured HNSCC cells and HNSCC xenograft animal models. The following anticancer mechanisms have been proposed: the inhibition of COX-2/PGE-2 pathway, the promotion of apoptosis, and the modulation of angiogenesis. In conclusion, Sal-B is a potential HNSCC chemopreventive agent working through antioxidation and anti-inflammation mechanisms.

    Head and neck squamous cell carcinomas (HNSCC) exhibiting resistance to the EGFR-targeting drug cetuximab poses a challenge to their effective clinical management. Here, we report a specific mechanism of resistance in this setting based upon the presence of a single nucleotide polymorphism encoding EGFR-K521 (K-allele), which is expressed in >40% of HNSCC cases. Patients expressing the K-allele showed significantly shorter progression-free survival upon palliative treatment with cetuximab plus chemotherapy or radiation. In several EGFR-mediated cancer models, cetuximab failed to inhibit downstream signaling or to kill cells harboring a high K-allele frequency. Cetuximab affinity for EGFR-K521 was reduced slightly, but ligand-mediated EGFR activation was intact. We found a lack of glycan sialyation on EGFR-K521 that associated with reduced protein stability, suggesting a structural basis for reduced cetuximab efficacy. CetuGEX, an antibody with optimized Fc glycosylation targeting the same epitope as cetuximab, restored HNSCC sensitivity in a manner associated with antibody-dependent cellular cytotoxicity rather than EGFR pathway inhibition. Overall, our results highlight EGFR-K521 expression as a key mechanism of cetuximab resistance to evaluate prospectively as a predictive biomarker in HNSCC patients. Further, they offer a preclinical rationale for the use of ADCC-optimized antibodies to treat tumors harboring thi
