    The cyst adenoid carcinoma is a rare malignant tumor that reaches principally the salivary glands; It is characterized by a clinical aggressiveness, the presence of peri neural invasions, frequent local recurrences and a high rate of metastases dissemination at delayed distance. The treatment is surgery with a postoperative adjuvant radiotherapy. for the patients suffering of inoperable tumors, the exclusive radiotherapy gives bad results with tests of use of heavy particles. The place of a hypo fractionated treatment on a stereotactic mode has not been evaluated, especially in dose complement after three dimensional irradiation. The purpose was to answer the following question if the Cyberknife was useful to deliver a complement of hypo fractionated stereotactic dose for the inoperable head and neck tumors. The limited number of patients does not allow a definitive conclusion. however, this therapy option seems interesting for the inoperable tumors subject to the management of the toxicity induced by the treatment. The evaluation of the irradiation volumes remains the critical element for the feasibility of this kind of protocol. (N.C.)

    The authors discuss the characteristics and the radiotherapy treatment procedures of cystic adenoid carcinomas, and more precisely the treatment of two of such cases of nasopharyngeal carcinomas. The first one had an incomplete resection surgery followed by curing radiotherapy: he has then been in local-regional control situation for 8 months. The second one had lung metastases, was treated chemotherapy and radiotherapy (decompressive treatment), and died six months after diagnosis. Radiotherapy is considered to be the treatment basis, whereas chemotherapy is a matter of controversy. Short communication

    Fourier transform infrared spectroscopic study of human breast normal and carcinomal tissues has been carried out. Some distinctive spectral differences which are mainly due to nucleic acids and proteins are observed between normal and carcinomal tissues. This method of analysis results in nearly 100% diagnostic accuracy of carcinomal tissues from normal tissues. The spectral patterns of well‐differentiated carcinomal tissues exhibit marked heterogeneity, however that of poorly differentiated...

    In 1978, Pratt challenged the otolaryngology community to identify an incidence of malignancy in individuals who have previously received radium therapy to the nasopharyngeal lymphoid tissues. This case report is a direct response to that quest and presents a well documented adenoid cystic carcinoma evolving 23 years after radium applicator treatment to the fossa of Rosenmuller. Although a cause-and-effect relationship cannot be scientifically proven, the case history raises several important questions concerning the stimulating effects of radiation on the later onset of frank malignancy.

  8. Plain radiographic evaluation of children with obstructive adenoids

    Background: There are several methods of evaluating adenoidal size pre-operatively. Plain nasopharyngeal radiography is a common investigative modality: it has been advocated, and also condemned. Aim: This study was intended to assess nasopharyngeal airway obstruction by the adenoids using plain X-rays; and also to find correlation if any, with the symptomatology. Methods: This is a retrospective study carried out between January and December 2008. The case notes and plain X-rays of the nasopharynx of 34 paediatric patients with clinical features of obstructive adenoids were analyzed. Results: A total of 34 children were studied, 22 (64.7%) were males and 12 (35.3%) were females. Their ages ranged between 7 months and 10 years: mean age was 3.55 years, standard deviation 2.723. Majority (67.6%) of the children were in the age group 0-4 years. The lowest symptomatology assessment score was 0 and the highest was 3. Children 4 years and below had the highest symptomatology scores. The minimum adenoidal-nasopharyngeal ratio was 0.35 and the maximum was 0.94. There was no significant difference in the mean adenoidal-nasopharyngeal ratio of males and females (t = 0.407; p = 0.692). Many (75.0%) of the children with moderate to severe nasopharyngeal airway obstruction by the adenoids were in the age bracket 0-4 years. The lowest adenoidal-nasopharyngeal ratio score was 0 and the highest was 3. Children 4 years and below had the highest adenoidal-nasopharyngeal ratio scores. There was a very weak nonsignificant correlation between the symptomatology assessment score and the radiological assessment score (r = 0.168; p = 0.375). Conclusion: The adenoidal-nasopharyngeal ratio is reliable in assessing the nasopharyngeal airway in children with obstructive adenoids.

    Full Text Available Background /Objectives: To study 30 cases of patients of chronic adenoiditis with adenoid facies and refractory chronic rhinosinusitis managed by endoscopic assisted adenoidectomy. Materials and method: 7 cases of adenoid facies and 23 cases of chronic refractory rhinosinusitis with adenoiditis were managed by endoscopic assisted adenoidectomy during the study period of 12 months from August 2012 to July 2013. Result: endoscopic assisted adenoidectomy proves to be more effective in managing adenoid facies and chronic refractory rhinosinusitis with adenoid hyperplasia. Conclusion: visualization of the adenoid mass using endoscope helps complete removal of the diseased adenoids. Endoscopic assisted adenoidectomy is treatment of choice in adenoid facies and chronic refractory rhinosinusitis with adenoid hyperplasia and more effective than conventional adenoidectomy.

    Nous rapportons le cas d'une tumeur colloïde du sein chez un homme. Cette situation rare interpelle par son mode de découverte. Nous avons pris en charge un homme de 60 ans atteint d'une lésion rétro-aréolaire droite classée cliniquement T4b N1 M0 et suspecte radiologiquement. L'analyse histologique (microbiopsie) a conclu à un carcinome colloïde muqueux associé à une petite composante canalaire classique de grade I de SBR du sein. Les traitements complémentaires associent mastectomie, curage, chimiothérapie, radiothérapie et hormonothérapie. Le cancer du sein est rare chez l'homme. Le carcinome colloïde est exceptionnel puisqu'il représente seulement 1 à 6% de l'ensemble des cancers du sein. Il est encore plus rare chez l'homme. Ces tumeurs touchent une population spécifique et ont un meilleur pronostic que les autres types prépondérant dans les cancers du sein chez l'homme. A travers cette observation et une revue de la littérature, nous essaierons de discuter les principales caractéristiques anatomo-cliniques et évolutives de cette forme rare du cancer du sein.

    Radiograph of the nasopharynx is still the most commonly used imaging method to investigate the adenoidal tissue. Due to the variety and complexity of proposed methods to measure the adenoid size, some radiologists prefer subjective evaluation, which can, however, be imprecise and inaccurate. We review and describe several methods to determine the adenoid size, taking into account the practicity, accuracy and precision with the aim of pointing out the best methods to be applied in daily routine practice.

    2003-12-01

    We report the case of a 74-year-old woman who developed a follicular ameloblastoma of the right mandible and 22 months later developed a cribriform adenoid cystic carcinoma of the soft palate on the right maxilla. The ameloblastoma was treated by hemimandibulectomy, and the adenoid cystic carcinoma was managed by resection of the soft palate and the surrounding tissue and bone followed by a 6-week course of radiotherapy. Our review of the literature indicates that only one similar case has been previously reported where an odontogenic tumor and a salivary gland tumor involved two different anatomic locations in the same patient at nearly the same time.

    Das, Somdipto; Nayak, Umanath K; Buggavetti, Rahul; Sekhar, Shobana

    2016-05-01

    The accessory parotid gland is salivary gland tissue separated from the main gland at a variable distance. This gland is histologically similar to the main gland, but has a higher incidence of malignant neoplasms than the main gland. Regarding the various malignant neoplasms, studies have shown higher incidences of mucoepidermoid carcinoma, with less than 2% being adenoid cystic carcinoma. We present a case of swelling in the midcheek region that, after clinical examination, was diagnosed as a case of neoplasm of the accessory parotid gland. On the basis of auxiliary investigations including intraoperative frozen section, it was concluded that it was adenoid cystic carcinoma, grade I, and after wide surgical resection, the tumor was removed without undergoing superficial parotidectomy. The patient received postoperative radiotherapy (RT) and was followed for 14 months without any recurrence or substantial facial asymmetry. PMID:26851989

    Le carcinome à cellules de Merkel (CCM) est une tumeur cutanée neuroendocrinerare d’évolution imprévisible et à grand potentiel métastatique. Ce néoplasme survient habituellement chez le sujet âgé au niveau des zones photo exposées. L'avidité constante du CCM au 18 fluorodésoxyglucose (FDG) justifie l'intérêt de la tomographie par émission de positon (TEP) au cours de cette pathologie. Toutefois, aucun consensus n'est établi à ce jour. Cette étude rapporte le cas d'une patiente de 25 ans suivie pour CCM métastatique, afin d'attirer l'attention sur cette tumeur particulière et d'illustrer l'intérêt de la TEP au 18 FDG dans la prise en charge de cette entité rare.

    2015-09-01

    Full Text Available OBJECTIVES: To identify the common bacteria found in the nasopharynx of patients of serous otitis media, to study the prevalence of adenoiditis in patient of serous otitis media and to study the bacteria isolated from operated adenoid tissue of patients of serous otitis media. METHOD AND MATERIA LS : Study was carried out on clinically diagnosed 40 cases of serous otitis media. Patients were operated under general anaesthesia. At the commencement of the surgery, a sterile swab was taken with an applicator from the surface of the adenoid. Prior to surgery, the adenoid tissue was palpated and confirmed. Adenoidectomy was done by curettage method using adenoid curette and the specimen was immediately transported in normal saline to the microbiology lab in a sterile bottle along with the surface swab. RESULT: 95% culture shows bacterial growth , males are more common in serous otitis media and most bacteria isolated from nasopharyngeal swab and adenoid are Gram positive bacteria includes Streptococcus pneumoniae, Staphylococcus aureus, Enterococcus species, Streptococcus viridians, Streptococcus pyogenes and Gram negative bacteria includes Moraxella catarrhalis, Klebsiella pneumonia. CONCLUSION: T he nasopharyngeal and adenoid bacterial flora is polymicrobial in nature and there is no difference in the pathogens isolated from nasopharynx swab or adenoid culture in patients of serous otitis media.

  6. [Immunomodulators for topical application to prevent and manage chronic adenoiditis in children].

    Garashchenko, T I; Zelenkova, I V; Alferova, M V

    2011-01-01

    The authors report the results of a study on the efficacy of topical application of the immunomodulator IRS 19 in children presenting with chronic adenoiditis and grade I-III hypertrophy of adenoid vegetation. The use of this preparation is shown to faster and more efficaciously normalize the volume of the lymphoid tissue than irrigation of the nasopharynx with saline solutions. Moreover, the treatment of chronic adenoiditis with IRS 19 promoted normalization of biocenosis of the nasopharyngeal secretion and significantly decreased the abundance of pathogenic microflora. Specifically, the overall frequency of exacerbations and the frequency of exacerbations of adenoiditis decreased three- and two-fold respectively while the duration of the disease shortened. It is recommended that the topical immunomodulator IRS 19 should be included in the programs of planned seasonal treatment of children suffering chronic adenoiditis (to be applied at least 2-3 times annually).

    Full Text Available Abstract Background Tracheal tumors are often misdiagnosed as asthma and are treated with inhaled steroids and bronchodilators without resolution. Case Presentation Here, a patient with tracheal adenoid cystic carcinoma who had been previously diagnosed with difficult asthma was reported. The possibility of the presence of localized airway obstruction was raised when the flow-volume curve suggesting fixed airway obstruction, was obtained. Conclusion The presenting case report emphasizes the fact that not all wheezes are asthma. It is critical to bear in mind that if a patient does not respond to appropriate anti-asthma therapy, localized obstructions should be ruled out before establishing the diagnosis of asthma.

  8. The CT evaluation of cephalic and cervical adenoid cystic carcinoma

    Objective: To evaluate the CT manifestations of cephalic and cervical adenoid cystic carcinoma (ACC). Methods: Thirty-three cases of ACC were analyzed retrospectively. Of all cases, 22 cases underwent operation and 11 cases received radiotherapy. The manifestations of CT were evaluated and compared with the clinical and pathologic results. Results: Tumors originated from parotid gland (5 cases), floor of mouth (5 cases), nasal cavity and nasopharynx (5 cases), tongue (4 cases), palate (3 cases), tracheas (3 cases), submandibular gland (2 cases), tonsilla (2 cases), maxillary sinus (2 cases), and cheek (2 cases), respectively. The CT manifestations included: (1)ethmoid density in 21 cases, partial ethmoid density in 5 cases. (2)the morphology of ACC was irregular and the growth of the tumor was amorphous in 17 cases, and the margin of the tumor was vague in 20 cases. (3)ACC often grew along the nerve with infiltration, which caused destruction of the skull base in 5 cases and atrophy of mastication muscles and/or buccinator in 3 cases. Conclusion: (1)The characteristics of cephalic and cervical adenoid cystic carcinoma on CT scans were ethmoid density, infiltrated growth, growing along the nerve with infiltration, and submucous growth. Among them, the most important manifestation, which could lead to the histologic diagnosis on CT, was ethmoid density. (2)The range of ACC was usually underestimated on CT. (3)The manifestation of tumor growth along the nerve could be apparently displayed on MRI

    Full Text Available INTRODUCTION: There is an ongoing debate about the existence and effects of Helicobacter pylori (Hp in adenotonsillar tissue. OBJECTIVE: A clinical study was conducted to assess the existence of Hp in the adenoid and/or adenotonsillar tissues, which were surgically excised due to chronic adenotonsillitis. METHODS: Phosphoglucosamine mutase gene for the detection of Hp and cytotoxin-associated gene as virulence gene were examined in 84 adenotonsillar tissues obtained from 64 patients and patients' serum by using polymerase chain reaction. RESULTS: Hp IgG was detected in 57 (89% patients' serum. A total of seven tissue samples from 64 patients (10.9% were found positive for Hp DNA, of which five were adenoids and two were tonsil tissues. All polymerase chain reaction positive samples were also positive for the cytotoxin-associated gene, which is a virulence determinant for the organism. CONCLUSION: This study suggests that children are exposed to Hp at an early age of their life in this province. Hp may have a role in the pathogenesis of chronic adenotonsillitis, especially in endemic areas.

    2015-01-01

    Introduction:Patients with nasopharyngeal carcinoma (NPC) sporadically develop abnormal adenoids. Nasopharyngeal adenoids are usually included in the gross tumor volume (GTV) but may have different therapeutic responses than tumor tissue. Therefore, distinguishing adenoids from tumor tissue may be required for precise and efficient chemoradiotherapy and radiotherapy. We characterized nasopharyngeal adenoids and investigated the therapeutic responses of NPC and nasopharyngeal adenoids using magnetic resonance imaging (MRI). Methods:MRI data from 40 NPC patients with a coexisting adenoid mass before and after treatment were analyzed. The features of the adenoid masses, including location, striped appearance, size, interface, symmetry/asymmetry, and cysts, were evaluated. Treatment response were scored according to the World Health Organization guidelines. Results:A striped appearance was observed in 36 cases before treatment and in all cases after treatment. In these 36 cases, the average GTVs including and excluding the uninvolved adenoids were 19.8 cm3 and 14.8 cm3, respectively. The average percentage change after excluding the uninvolved adenoids from the GTV was 31.0%. Stable disease in the adenoids was identified in 27 (96.4%) of 28 patients after neoadjuvant chemotherapy, while NPC clearly regressed. Partial adenoid responses were identified in 33 (82.5%) of 40 patients at 3 months after chemoradiotherapy or radiotherapy, whereas complete tumor responses were achieved in all patients. Six months after treatment, the adenoids continued to atrophy but did not disappear, and tumor recurrence was not found. Conclusions:Nasopharyngeal adenoids and carcinoma tissue in NPC patients can be distinguished by using MRI and have different responses to chemoradiotherapy and radiotherapy. These findings contribute to better delineating the GTV of NPC, based on which spatially optimized strategies can be developed to render precise and efficient chemoradiotherapy and

    2016-01-01

    Introduction. Adenoid hypertrophy (AH) is a common childhood disorder. Adenoid plays a significant role in the pathogenesis of otitis media with effusion (OME). The aim of this study is to critically appraise the tympanometric finding among children with adenoid hypertrophy in Port Harcourt, Nigeria. Methodology. A Prospective, controlled study carried out among newly diagnosed cases of adenoid hypertrophy at the ENT clinic of the UPTH, between November 2014 and June 2015. Tympanometry was done on each child and each ear was considerably studied as a single entity. Types B and C tympanograms were used as indicators of OME. Data was collected and analyzed using SPSS version 20. Results. Sixty-eight cases of adenoid hypertrophy were seen within the study period and 136 ears were studied. Forty (29.4%) ears had type B tympanogram, while 36 (26.5%) ears had type C. The incidence of OME was 55.9%; there were 12 (17.6%) unilateral OME, while bilateral OME was 32 (47.1%). Grade 3 AH was prevalent and was statistically significant with the OME. Conclusion. This study had shown adenoidal hypertrophy as a significant risk factor for OME in children. There was more bilateral OME than unilateral. The more severe grade of AH was more prevalent and it was shown to be statistically significant with OME, thus being a significant risk factor for OME in children. This establishes the need for prompt hearing evaluation and management. PMID:27563311

    We present the case of a child with chronic adenoiditis caused by a PspK+ NESp. We tested the pneumococcal isolate, designated C144.66, for antimicrobial resistance, the presence of the pspK gene and the expression of PspK. Sequence typing and genome sequencing were performed. C144.66 was found to be resistant to erythromycin and displayed intermediate resistance to penicillin and trimethoprim/sulfamethoxazole. C144.66 has the pspK gene in place of the capsule locus. Additionally, PspK expression was confirmed by flow cytometry. NESp are a growing concern as an emerging human pathogen, as current pneumococcal vaccines do not confer immunity against them. An inability to vaccinate against NESp may result in increased carriage and associated pathology.

    Adenoid cystic carcinoma (ACC) of the breast is a rare type of tumor. Our objective was to determine the clinicopathologic features of breast ACC. We reviewed slides of breast ACC reported during 12 years. Seven cases were identified. Age ranged from 38 to 59 years (mean = 47 years). Mean tumor size was 2.3 cm (range 1.2 to 4 cm). Histologically, dominant cribriform pattern was seen in 4 cases, solid in 2 and tubular in one case. Mitotic figures ranged from 2 to 22/10 HPFs. Grades I and II were seen in 3 cases each while 1 was grade III. Post-surgical tamoxifen given in 3 cases, chemotherapy and radiotherapy in 2 and 1 case, respectively. Follow-up ranged from 12.5 - 138.5 months (mean = 61. 25 months). One patient developed vertebral metastasis. Consistent with published data, this series indicated that ACC-breast has a good prognosis. PMID:27225150

  16. Adenoid cystic carcinoma of sublingual glands. Surgery and radiotherapy combination

    The Adenoid Cystic Carcinoma (ACC) or Cilindroma is a strange entity classified by the WHO within the carcinomas of salivary glands. It represents only 1 % of all the wicked tumours of the oral and maxillofacial region although, when making reference to the salivary glands, it constitutes 5% of the parotid, submaxilar and sublingual carcinomas, and about 50% of the smallest ones. The most frequent location is in the palatine glands and its main characteristics are: slow but persistent growth, high rates of local relapse and metastasis at distance originating the death between the first 5 and 10 years in 50-70% of the cases approximately. A case of localization is presented in sublingual gland which was first treated surgically and later with radiotherapy, obtaining good results. (author)

    2012-01-01

    Full Text Available Adenoid cystic carcinoma (ACC occurs more commonly in the minor salivary glands of the palate on than the tongue. ACC is a malignant neoplasm that accounts for 1-2% of all head and neck malignancies and 10-15% of all salivary gland malignancies. ACC affects the exocrine glands at any site, but the parotid gland is the most common site in the head and neck region. Many factors should be taken into account in the prognosis of ACC, including the histological and clinical stages of the disease. The most striking feature of ACC is that it is locally aggressive, with a high recurrence level, perineural invasion and distant metastases, especially to the lungs and bones. The most common presentation histologically is the presence of cribriform appearance (Swiss cheese pattern. The present case is a rare one present on the tongue.

    2013-01-01

    Full Text Available Adenoid cystic carcinoma (ACC accounts for approximately 6-10% of all salivary gland tumors. Palatal minor salivary glands, parotid, and sub-mandibular glands are usually affected. Rarely, these lesions arising intraosseously have been reported. Mandible is commonly involved than maxilla. The present case is a giant ACC involving the right maxilla. A thorough clinical and radiographic evaluation was performed to assess the involvement of surrounding vital structures along with a meticulous metastatic work-up. Computed tomography showed a giant lesion in maxilla encroaching the left nasal fossa, antrum, buccal space, and oral cavity. No metastasis was noted. Histological evaluation from multiple sites showed both cribriform and solid patterns. Radiotherapy was given as patient did not comply for surgery. Though central ACC is extremely rare, especially in maxilla, it should be included in the differentials for lesions in maxilla. A prompt diagnosis with treatment and long-term follow-up is advised in such cases.

    Les carcinomes épidermoides du sein sont rares. Ils sont d'origine métaplasiques. Leur histogénèse est controversée. La présentation clinique et mammographique n'est pas spécifique, l'aspect kystisé des lésions et la présence de nécrose sont recherchés à l’échographie mammaire. Le diagnostic est histologique. Ce cancer est réputé être peu lymphophile et non hormonodépendant. Le traitement rejoint celui des carcinomes infiltrants canalaires et repose sur la chirurgie, la radiothérapie et la chimiothérapie. Le pronostic est péjoratif. Nous rapportons trois cas de carcinome épidermoide du sein colligés au service de Gynécologie obstétrique II au CHU Hassan II de Fès et une revue de la littérature.

    2006-07-01

    Full Text Available Background and Aim: Adenoids are normally large in children and their size starts to reduce during adolescence. Hypertrophic adenoids could be associated with allergic reactions. Enlarged adenoids result in nasal breathing difficulties and the child is forced to switch to mouth breathing. Airway obstruction causes postural alterations of jaw, tongue and head, and due to persistent obstruction, patient’s appearance changes to adenoid face. Evaluation of nasopharyngeal space in lateral cephalometic view is a simple and repeatable method for determination of the size and shape of adenoids and nasopharyngeal space which can provide a simple measurement of nasopharyngeal obstruction. The roof of nasopharyngeal space is covered by the sphenoid bone. Thus changes of nasorespiratory resistance by hypertrophic adenoids may affect the cranial base angles. In this study, the relationship between adenoid hypertrophy and cranial base angles was investigated. Materials and Methods: In this descriptive-analytic study, lateral cephalometric views of 7 to 14 y/o patients from the files of orthodontic centers in Rasht city were selected. The radiographs with proper resolution were separated for this research. Adenoid to nasorespiratory ratio (A/N Ratio was determined by Fujioka method and categorized in three groups: A (A/N 0.8, B (0.5adenoid hypertrophy (A and B groups was observed in 66% of cases whereas 34% were normal. The frequency of narrow, normal and wide cranial base angles

  3. Neutron radiotherapy for adenoid cystic carcinoma of minor salivary glands

    Purpose: To examine the efficacy of fast neutron radiotherapy for the treatment of patients with locally advanced, adenoid cystic carcinoma of minor salivary glands and to identify prognostic variables associated with local control, overall survival, and cause specific survival. Methods and Materials: Eighty-four patients having adenoid cystic carcinoma of minor salivary glands were treated with fast neutron radiotherapy during the years 1985-1994. All patients had either unresectable disease or gross disease remaining after attempted surgical extirpation. Seventeen patients had previously received conventional radiotherapy and their subsequent treatment fields and doses for neutron radiotherapy were modified for critical sites (brainstem, spinal cord, brain). Although the median doses (tumor maximum and tumor minimum) only varied by ≤10%, treatment portals were substantially smaller in these patients because of normal tissue complication considerations. Twelve patients (13%) had distant metastases at the time of treatment and were only treated palliatively with smaller treatment portals and lower median tumor doses (≤80% of the doses delivered to curatively treated patients). Seventy-two patients were treated with curative intent, with nine of these having recurrent tumors after prior full-dose radiotherapy. The median duration of follow-up at the time of analysis was 31.5 months (range 3-115). Sites of disease and number of patients treated per disease site were as follows: paranasal sinus--31; oral cavity--20; oropharynx--12; nasopharynx--11; trachea--6; and other sites in the head and neck--4. Results: The 5-year actuarial local-regional tumor control rate for all patients treated with curative intent was 47%. Patients without involvement of the cavernous sinus, base of skull, or nasopharynx (51 patients) had a 5-year actuarial local-regional control rate of 59%, whereas local-regional control was significantly lower (15%) for patients with tumors involving

  4. Radiologic evaluation of adenoids and tonsils in children with obstructive sleep apnea: Plain films and fluoroscopy

    Kreplick Fernbach, S.; Brouillette, T.; Riggs, T.W.; Hunt, C.E.

    1983-07-01

    Twenty-six children with obstructive sleep apnea were evaluated by lateral neck radiographs during wakefulness, and by polygraphic monitoring and upper airway fluoreoscopy during natural sleep. Children with craniofacial abnormalities, palatal surgery, and central nervous system disease were excluded from the study. Moderate or marked enlargement of tonsils and adenoids was noted on lateral neck radiographs of 18 of 26 patients. An objective measure of adenoidal enlargement, the adenoidal-nasopharyngeal ratio, correlated well with subjective judgment of adenoidal size but was not generally more useful than subjective estimation. Upper airway fluroescopy demonstrated the site and mechanism of obstruction in all patients. Because all children with moderate to marked adenotonsillar enlargement demonstrated obstruction at the adenoidal or tonsillar level on fluoroscopy, we now screen children with suspected sleep apnea with lateral airway radiographs and polysomnography. Fluoroscopy is reserved for children with mild adenotosillar enlargement, craniofacial dysplasia, prior cleft palate repair, or neuromuscular disorders. These results suggest that the pathogenesis of obstuctive sleep apnea in children involve anatomic factors which narrow the upper airway, sleep-related hypotonia of pharyngeal dilator musculature, and compensatory mechanisms to prevent or alleviate asphyxia.

  5. The value of radiological examination in the management of adenoidal hypertrophy in a pediatric population

    The objective of this study is to evaluate the role of radiological examination in the management of adenoidal hypertrophy. A retrospective study was carried out in the North West Armed Forces Hospital, Tabuk, Kingdom of Saudi Arabia on pediatric patients who had x-ray of lateral nasopharynx to exclude adenoidal hypertrophy, January 2001 to December 2001. The study included ; the age of patient, sex and reason for radiology examination and management rendered. A total of two hundred and ninety- seven pediatric patients were involved. Two hundred and thirteen males (71.7%) and 84(28.3%) females, age ranged between 2 months and 12 years. The reason given for radiological examination was one or more of following symptoms snoring,mouth breathing recurrent tonsillitis, runny nose, deafness and obstructive sleep apnea.Small adenoids reported in 63 patients (21.2%)and were treated for their complaints by primary physician. Two hundred and thirty four patients (78.8%) with large adenoids were referred to the otolaryngology department of these 33 patients lost follow up. One hundred and nineteen referred(40.1%) patients were treated conservatively, while 82 patients (27.6%) who showed resistance to medical treatment under went adeniodectomy with or without other related surgical procedures. It was concluded that radiological examination in the management of adenoidal hypertrophy had a limited role, increased Radiological Department workload wastage of resources in addition to unnecessary radiation exposure.

    Ben Salha, Imen; Bhide, Shree; Mourtzoukou, Despoina; Fisher, Cyril; Thway, Khin

    2016-08-01

    Adenoid cystic carcinoma (ACC) is a malignant neoplasm that mainly affects the salivary glands but has been described in many other anatomical sites. It is composed of basaloid cells with myoepithelial/basal cell differentiation and ductal epithelial cells that proliferate in a fibrous stroma, with variable amounts of myxohyaline material. Three patterns (cribriform, tubular, and solid) occur, and the solid variant is characterized by a predominant compact sheet-like and nested pattern of rounded basaloid cells lacking obvious cribriform or tubular architecture. The solid variant has significant morphological and immunohistochemical overlap with a large range of neoplasms of different lineages, including other carcinomas and sarcomas. We describe a case of solid variant ACC of the paranasal sinuses, which showed an almost entirely solid pattern of growth (in >95% of cells) and which on initial biopsy showed no features of classical ACC. This highlights the potential for diagnostic misinterpretation with a variety of other neoplasms, which is particularly important because of the significant difference in treatment for ACC and tumors in its differential diagnosis.

    Full Text Available This study presents the treatment of 68 children with secretory otitis media. Children underwent adenoid vegetations, nasal speech, conductive hearing loss, ventilation disturbance in Eustachian tube. In all children adenoidectomy was indicated.38 boys and 30 girls at the age of 3-17 were divided in two main groups: * 29 children without hypertrophic (enlarged adenoids, * 39 children with enlarged (hypertrophic adenoids.The surgical treatment included insertion of ventilation tubes and adenoidectomy where there where hypertrophic adenoids.Clinical material was analyzed according to hearing threshold, hearing level, middle ear condition estimated by pure tone audiometry and tympanometry before and after treatment. Data concerning both groups were compared.The results indicated that adenoidectomy combined with the ventilation tubes facilitates secretory otitis media heeling as well as decrease of hearing impairments. That enables prompt restoration of the hearing function as an important precondition for development of the language, social, emotional and academic development of children.

    2015-01-01

    Patient âgé de 59 ans ayant consulté pour un syndrome douloureux et fébrile de l'hypochondre droit évoluant depuis quatre jours. La palpation trouvait une défense et la biologie montrait un syndrome inflammatoire biologique associé à une cholestase anictérique. A l’échographie la vésicule biliaire était distendue, multi lithiasique, à paroi épaissie, associée à un aspect hypoéchogène du segment IV du foie et une thrombose de la branche portale gauche. L'exploration per opératoire, montrait un pyocholécyste, une vésicule biliaire enchâssée dans le foie avec une importante pédiculite et un segment IV induré sans abcès hépatique. Une cholécystectomie avec drainage étaient réalisées. L'examen anatomopathologique était en faveur d'un carcinome épidermoïde bien différencié occupant toute la vésicule biliaire et infiltrant toute la paroi en dépassant la séreuse. Cette tumeur était classée stade pT3 selon la classification TNM et la limite d'exérèse proximale était tumorale. Malgré une chimiothérapie palliative à base de Gemzar- Cisplatine l’évolution était rapidement défavorable. PMID:27047622

    Korona-Glowniak, I; Niedzielski, A; Kosikowska, U; Grzegorczyk, A; Malm, A

    2015-03-01

    Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis and Staphylococcus aureus colonization of the adenoids and nasopharynx in 103 preschool children who underwent adenoidectomy for recurrent upper respiratory tract infections was examined. Bacterial interactions and risk factors for bacterial colonization of the nasopharynx and adenoids, separately, were analysed statistically. The prevalence of simultaneous isolation from both anatomical sites was 45·6% for S. pneumoniae, 29·1% for H. influenzae, 15·5% for M. catarrhalis and 18·4% for S. aureus. Three pathogens were significantly more frequent together from adenoid samples; nasopharyngeal swabs more often yielded a single organism, but without statistical significance. M. catarrhalis and S. aureus significantly more frequently co-existed with S. pneumoniae and H. influenzae than with each other and a positive association of S. pneumoniae and H. influenzae in adenoid samples was evident. Several differences between risk factors for nasopharyngeal and adenoid colonization by the individual pathogens were observed. We conclude that the adenoids and nasopharynx appear to differ substantially in colonization by pathogenic microbes but occurrence of H. influenzae and S. pneumoniae in the nasopharynx could be predictive of upper respiratory tract infections.

    Archana Buch

    2015-01-01

    Full Text Available Adenoid cystic carcinoma (ACC is a rare neoplasm that usually arises from minor salivary glands. It is characteristically locally infiltrative, exhibiting perineural invasion, has a tendency for local recurrence and prolonged clinical course. A 60 year old male, chronic smoker presented with swelling of the left cervical lymph node since two months. Examination revealed a solitary firm, non tender, non mobile left cervical swelling measuring 2 x 1 cm. Fine Needle Aspiration Cytology (FNAC was done from the cervical lymph node. The diagnosis of metastatic deposits of ACC was given. Detail examination of the oral cavity revealed a small swelling at the floor of the mouth. Biopsy of the swelling confirmed ACC on histopathological examination. An unusual feature of adenoid cystic carcinoma is the low incidence of metastases to regional lymph nodes. The case is presented to highlight its unusual presentation and utility of FNAC in rapid diagnosis.

    Objective: To investigate the expression of epidermal growth factor receptor, a receptor tyrosine protein kinase, in the subcellular fractions of human salivary adenoid cystic carcinoma cell lines SACC-83 and SACC-LM. Methods: Low metastatic and high metastatic cells of the adenoid cystic carcinoma, SACC-83 and SACC-LM, were cultured. Their subcellular fractions were extracted. The expression of epidermal growth factor receptor was detected with Western blot method, and the results of protein expression were quantitatively analyzed by FluorChem V2.0 software. Results: The results of Western blot analysis indicated that, EGFR expression on the membrane of SACC-83 cells was significantly higher than that of SACC-LM cells, but its expression in cytoplasm was significantly less in the former than the later (P<0.01). In SACC-83 cell line, EGFR was over-expressed in membrane (P<0.01), but in SACC-LM cell line, EGFR was over-expressed in cytoplasm (P<0.01). Conclusion: The results suggest that the obtaining of metastasis ability is related to the high expression of EGFR protein in cytoplasm, so the molecular targeting therapy to EGFR may be an ideal treatment for the invasion and metastasis of salivary adenoid cystic carcinoma.

    Adherence of fimbriated and nonfimbriated variants of a single strain of Haemophilus influenzae type b to organ cultures of human adenoidal tissue was measured by three assays, two of which were quantitative. In one assay, the adherence of radioactively labeled bacteria was measured; the numbers of CFU of bacteria per gram of adenoidal tissue were 16.0 +/- 6.7 for fimbriated bacteria and 10.2 +/- 4.0 for nonfimbriated bacteria (P less than 0.05). In the second assay, adherent CFU were determi...

    2016-01-01

    We report a case of video-assisted thoracoscopic surgery (VATS) tracheal resection and carinal reconstruction in a patient with tracheal tumor. The patient presented with adenoid cystic carcinoma (ACC) of the distal trachea, extending along the right main bronchus with carinal invasion. The reconstruction procedure was assisted with cross-field ventilation. Postoperative clinical course of this case was good. The forced expiratory volume in the first second (FEV1) improved from 0.461 L (17% pred.) to 2.31 L (87% pred.) 1 month after the operation. VATS tracheal resection and carinal reconstruction is a feasible option for patients with tracheal tumor with carina involvement. PMID:26904230

  8. Adenoid basal lesions of the uterine cervix: evolving terminology and clinicopathological concepts

    2006-08-01

    Full Text Available Abstract The epithelial proliferations that are designated adenoid basal carcinoma (ABC in the current classification from the World Health Organization represent 15%. The biologic course of ABCs that are associated with separate malignancies is largely dependent on the clinicopathologic parameters of the associated malignancies. Morphologically pure lesions, in contrast, have largely been associated with favorable patient outcomes, as none of the 66 reported patients have experienced tumor recurrence, metastases or tumor-associated death, irrespective of the modality of treatment. Although the finding of genome integrated high-risk human papillomavirus (HPV types and p53 alterations in adenoid basal lesions (ABL argue in support of their neoplastic nature, we identified no lines evidence that suggest an inherent malignancy for morphologically pure lesions. The finding of morphologic transitions between ABLs and conventional malignancies and shared HPV types in these areas, suggest that ABLs have some malignant potential. However, the precise magnitude of this potential is not readily quantifiable and should not dictate the management of morphologically pure lesions that are entirely evaluable. ABLs continue to occupy a unique position in human oncology in which the term carcinoma (without an in-situ suffix is applied to a tumor that has not been shown to recur, metastasize or cause death. We concur with a previous proposal that the term ABC should be discarded and replaced with Adenoid Basal Epithelioma (ABE. In our opinion, there is insufficient evidence at present time to expose patients with morphologically pure lesions to the ominous implications – social, psychological, medical, financial – of a "carcinoma" diagnosis. Morphologically impure lesions should not be designated ABC or ABE. Furthermore, given the uncertainties regarding the frequency with which ABE are associated with separate malignancies, we suggest that the ABE

    Human bocavirus 1 (HBoV1) is associated with respiratory infections worldwide, mainly in children. Similar to other parvoviruses, it is believed that HBoV1 can persist for long periods of time in humans, probably through maintaining concatemers of the virus single-stranded DNA genome in the nuclei of infected cells. Recently, HBoV-1 was detected in high rates in adenoid and palatine tonsils samples from patients with chronic adenotonsillar diseases, but nothing is known about the virus replic...

    2004-12-01

    Metastasis and invasion, the important characteristics of malignant tumors, are closely associated with a series of changes in the expression of genes and proteins. In this study, we compare mRNA and protein expression in high and low metastasis adenoid cystic carcinoma cell lines by mRNA suppression subtractive hybridization and two-dimensional electrophoresis combined with peptide mass fingerprint analysis. 34 differentially expressed genes were obtained using suppression subtractive hybridization experiments including 6 highly expressed gene sequences in the high metastasis cell line, and 28 in the low metastasis cell line. RNA dot blot hybridization further confirmed the results after excluding false positives. For protein analysis, ten significantly different protein spots were detected using two-dimensional gel electrophoresis technique combined with matrix-assisted laser desorption/ionization time-of-flight mass spectrometer (MALDI- TOF-MS). The results then compare with the SWISS PROT database. These results suggest that high tumor metastasis of adenoid cystic carcinoma is associated with multiple genes whose function include angiogenesis, protein synthesis, signal transduction, modulation of cell cycle, molecular chaperones, and immune co-stimulating molecule. Moreover, the results of the phenotypic function-related expression mapping analysis at the mRNA and protein level revealed obvious complementarities, providing important clues for further study of the molecular mechanism of metastasis, metastasis control and possible targets for cancer gene therapy.

  11. Epithelial Cell Culture from Human Adenoids: A Functional Study Model for Ciliated and Secretory Cells

    Claudia González

    2013-01-01

    Full Text Available Background. Mucociliary transport (MCT is a defense mechanism of the airway. To study the underlying mechanisms of MCT, we have both developed an experimental model of cultures, from human adenoid tissue of ciliated and secretory cells, and characterized the response to local chemical signals that control ciliary activity and the secretion of respiratory mucins in vitro. Materials and Methods. In ciliated cell cultures, ciliary beat frequency (CBF and intracellular Ca2+ levels were measured in response to ATP, UTP, and adenosine. In secretory cultures, mucin synthesis and secretion were identified by using immunodetection. Mucin content was taken from conditioned medium and analyzed in the presence or absence of UTP. Results. Enriched ciliated cell monolayers and secretory cells were obtained. Ciliated cells showed a basal CBF of 10.7 Hz that increased significantly after exposure to ATP, UTP, or adenosine. Mature secretory cells showed active secretion of granules containing different glycoproteins, including MUC5AC. Conclusion. Culture of ciliated and secretory cells grown from adenoid epithelium is a reproducible and feasible experimental model, in which it is possible to observe ciliary and secretory activities, with a potential use as a model to understand mucociliary transport control mechanisms.

  12. Helicobacter pylori in tonsillar and adenoid tissue and its possible role in oropharyngeal carcinogenesis.

    Lukes, P; Astl, J; Pavlík, E; Potuzníková, B; Sterzl, I; Betka, J

    2008-01-01

    Helicobacter pylori is a well-known gastric pathogen. It plays a major role in the pathogenesis of chronic gastritis, duodenal and gastric ulcers, adenocarcinoma and gastric lymphoma. HP infection is one of the most common bacterial infections worldwide. Recently, the oral cavity was proposed as an extragastric reservoir of HP infection. HP was detected by culture and PCR in both dental plaque and saliva. It is supposed that HP infection can cause the same immunological changes in the oropharyngeal mucosa as in gastric mucosa and can also contribute to the progression of oropharyngeal diseases. HP can induce production of different cytokines and regulatory molecules, which are suggested to play a role in carcinogenesis of the oropharynx. Only a few studies have explored the presence of HP in tonsillar and adenoid tissue, where MALT is present similar to the gastric mucosa. The results of these studies were inconsistent. The question of persistence of HP in tonsillar and adenoid tissue and its role in the pathogenesis of oropharyngeal diseases still remains unclear. In this review, recent findings about oral HP are considered. Possibilities of diagnostics of HP in oral specimens are discussed. PMID:18498719

  13. Biological behavior and Treatment of Adenoid Cystic Carcinoma in the Head and Neck

    Biological Behavior and treatment results of 33 patients with Adenoid Cystic Carcinoma (ACC) in the Head and Neck at Yonsei Cancer Center for 10 years between 1971 and 1980 were retrospectively analyzed. Most common, primary site was minor salivary glands such as maxillary sinus, nasal cavity and base of tongue. The typical biological behavior of these tumors was very slowly in growth with long rime of duration (mean 19 months) from I month to 10 years and more frequent of nerve invasion but rare invasion of neck nodes. Local control and failure pattern in the results of treatment, 16 of 17 patients with irradiation alone were seen complete or partial response but 5 cases of loco regional recurrence, 2 cases of failure of neck node and 4 cases of distant metastasis as lung and brain. On the other hand, among 10 cases of surgery and postoperative irradiation, 2 cases of locoreginal failure and 3 cases of distant metastasis as lung and bone. 2 of 4 cases with surgery alone were recurred within primary site. Actuarial overall NED survival at 5 and 10 years were 52.6% and 42.8%, respectively. Survival rate of 10 patients with surgery and postoperative irradiation was more high than 17 patients of radiation alone. Therefore, we have known that surgery with postoperative adjunctive irradiation is most effective treatment modality of adenoid cystic carcinoma in the head and neck. Primary site, treatment modality and with or without nerve and bone invasion have influenced on prognosis

  14. Clinicopathological study of 54 cases of adenoid cystic carcinoma in the head and neck

    A retrospective analysis was performed on 54 patients with adenoid cystic carcinoma in the head and neck, treated from January 1971 to July l997 in the Kurume University Hospital. The patients consisted of 35 females and 19 males, with a mean age of 59 years. The site of the lesion was the oral cavity in 13, nasal cavity in 11, submandibular gland in 8, parotid gland in 5, paranasal sinus in 3, nasopharynx in 3, oropharynx in 3, external auditory canal in 3, orbita in 2, lip in 1, lacrimal gland in 1 and trachea in 1. The over all 5-year, 10-year and 15-year survival rates as determined by the Kaplan-Meier method were 72%, 53%, and 46%, respectively. There was no relationship between survival rate and the site of the original lesion. According to the histologic criteria reported by Szanto et al., when more than 30% of the neoplasma showed a solid pattern, its treatment outcome appeared poor. In this study, the same tendency was seen. Fifteen patients died of the tumor. Ten died of distant metastasis and 5 died of local recurrence invading the cranium. No patient died of neck metastasis. Adenoid cystic carcinoma was thought to be radioresistant, but recently some authors have reported this tumor as radiosensitive. This study also showed that postoperative radiotherapy was effective, producing an increase in the survival rate. (author)

  15. Lacrimal gland adenoid cystic carcinoma: intracranial and extracranial en bloc resection.

    Marsh, J L; Wise, D M; Smith, M; Schwartz, H

    1981-10-01

    Adenoid cystic carcinoma of the lacrimal gland is a rare tumor, although it is the malignancy most frequently arising in the gland. Treatment has been unsuccessful generally, with a 15-year survival of less than 20 percent. Our experience with this tumor in a 61-year-old woman has led to a proposal for therapeutic management based on awareness of the lesion's natural history, an understanding of regional anatomy, and familiarity with therapies reported in the literature. The feasibility of adequate tumor ablation is determined from preoperative evaluation, including CT scan, initial exploratory craniotomy, and frozen-section examination of the cranial nerves transversing the orbit. Once resectability is confirmed, "curative" intracranial and extracranial en bloc resection is performed, including the tumor, the lacrimal gland, and all contiguous structures. The defect is immediately resurfaced with and "ice cream cone" forehead flap in anticipation of adjuvant radiotherapy. An orbital prosthesis is fitted as soon as the radiation reaction subsides, and a postablative CT scan is obtained as the baseline for follow-up. It remains to be seen whether this application of the technology of CT scanning and the techniques of craniofacial surgery will improve the prognosis for adenoid cystic carcinoma arising in the lacrimal gland.

    REN Dong-dong; WANG Wu-qing

    2012-01-01

    Background Otitis media with effusion is a highly concurrent disease in young children with adenoid hypertrophy.The aim of this study was to assess the middle ear effusion and audiological characteristics in children with adenoid hypertrophy and compare the various assessment methods.@@Methods Two hundred and seven candidates who were to undergo adenoidectomy were analyzed using otoscopy,tympanometry,air-conduction auditory steady-state responses (AC-ASSR),and computerized tomography (CT) before adenoidectomy.@@Results About 73.4% (304/414) of ears were confirmed to have middle ear effusion (MEE) by otoscopy; 75.4% (312/414) of ears revealed MEE by CT.CT scan correctly predicted all the myringotomy results,giving 100% accuracy on the diagnosis of MEE.Additionally,CT revealed two children with inner ear malformations.Type B tracing tympanogram provided a sensitivity of 91.7% and a specificity of 92.2%.Type C tympanogram with peak pressure <-200 daPa indicated effusion; type C tympanogram having acoustic stapedius reflex could exclude MEE.We excluded the AC-ASSR results of the 4 ears with malformation; 54.4% (223/410) of ears were confirmed of hearing loss.Furthermore,5.2%(16/310) of the ears with MEE suffered from severe to profound hearing loss.The average threshold level in the 0.25 kHz frequency of children was found to have poorer hearing thresholds than those in the 0.5,1,2,and 4 kHz (P <0.001) frequencies; 29.7% (92/310) of ears with MEE were regarded as normal hearing level.About 55.8% (173/310) of ears with MEE were classified as having slight-mild hearing loss.@@Conclusions The practitioners should pay much attention to the middle ear condition and be aware of a possible development of severe to profound hearing loss during the course of MEE in young children with adenoid hypertrophy.CT scan is good for the assessment of MEE before ventilation tube insertion.

  19. Adenoid cystic carcinoma: A rare late presentation of the mobile tongue

    Kumar, Sanjay; Agarwal, Padmanidhi; Nimmi, V.

    2016-01-01

    Adenoid cystic carcinoma (ACC) is an infrequent malignant neoplasm of the salivary glands. We present a case of a 70-year-old male patient with a swelling over the dorsal and ventral surface of anterior two third of the tongue which was causing him difficulty in mastication since 10 months. Ultrasound and magnetic resonance imaging were done following which the surgical excision of the lesion was performed and histopathological diagnosis of ACC was achieved. It was rare to find ACC in such an old man with such a large lesion presenting so late in the rare site of the mobile tongue. ACC is a slowly growing, highly invasive cancer with a high recurrence rate and chances of metastases, so surgery is the choice of treatment with mandatory long-term follow-up. PMID:27195216

  20. Identification of acid-sensing ion channels in adenoid cystic carcinomas

    Tissue acidosis is an important feature of tumor. The response of adenoid cystic carcinoma (ACC) cells to acidic solution was studied using whole-cell patch-clamp recording in the current study. An inward, amiloride-sensitive Na+ current was identified in cultured ACC-2 cells while not in normal human salivary gland epithelial cells. Electrophysiological and pharmacological properties of the currents suggest that heteromeric acid-sensing ion channels (ASICs) containing 2a and 3 may be responsible for the proton-induced currents in the majority of ACC-2 cells. Consistent with it, analyses of RT-PCR and Western blotting demonstrated the presences of ASIC2a and 3 in ACC-2 cells. Furthermore, we observed the enhanced expression of ASIC2a and 3 in the sample of ACC tissues. These results indicate that the functional expression of ASICs is characteristic feature of ACC cells

    Adenoid cystic carcinoma (ACC) is a subtype of adenocarcinoma that is usually seen in the salivary glands. It has also been reported in other organs including the breast, skin, tracheobronchial tree, cervix, larynx, and Bartholin gland. ACC in the breast is rare, accounting for less than 0.1% of all breast cancers. Furthermore, the imaging characteristics of ACC of the breast have not been well described in the literature, especially regarding the findings with magnetic resonance imaging (MRI). Here, we report radiologic findings of a rare case of ACC in the breast by mammography, sonography, computed tomography (CT), positron emission tomography/CT, and MRI with pathologic correlation and a review of the literature.

  2. Nasal Mucociliary Clearance in Adenoid Hypertrophy and Otitis Media with Effusion.

    Yazıcı, Hasmet

    2015-12-01

    Mucociliary clearance (MCC), which exists in many systems, is the first defensive mechanism of the human body. Nasal MCC has an important role in transporting the secretions of the nasal cavity and paranasal sinuses along with the trapped inhaled pathogens to the nasopharynx. Physiologic or pathologic situations that effect nasal MCC, such as temperature, humidity, nasal obstruction, allergic rhinitis, chronic infections, etc., lead to impaired MCC and related local or circumjacent system disorders. With this perspective, when a unified airway with a multiple disease principle is considered, investigating the relationship between adenoid hypertrophy (AH), otitis media with effusion (OME) and nasal MCC is logical. In this review, histological and physiologic properties of nasal MCC and its possible role involving pathologic situations such as AH and OME is discussed together with recent literature findings.

  3. ANTIMETASTATIC EFFECT OF INTEGRIN IIb/IIIa INHIBITORS ON SALIVARY ADENOID CYSTIC CARCINOMA

    2001-01-01

    Objectives: To investigate the relation between metastatic potential of salivary adenoid cystic carcinoma (SACC) and tumor cell-platelet adhesion, and the antimetastatic effect of integrin IIb/IIIa inhibitor on SACC. Methods: Tumor cell-platelet adhesion of highly metastatic SACC-LM, non-highly metastatic SACC-83 and effect of aspirin, arginine-aspartate (RD), magnesium acetylsalicylate on adhesion were studied in vitro. Antimetastafic effect of aspirin, RD, magnesium acetysalicylate on experimental metastasis of SACC was observed in vivo. Results: The tumor cell-platelet adhesion was stronger in SACC-LM than in SACC-83. Aspirin, RD and magnesium acetylsalicylate could inhibit the adhesion of SACC-LM at the concentration of 1, 5 and 25 mg/ml. RD can inhibit experimental metastasis of SACC. Conclusion: Metastasis of SACC is related to platelet-tumor cell adhesion, RD could inhibit metastasis of SACC.

  4. A subset of prostatic basal cell carcinomas harbor the MYB rearrangement of adenoid cystic carcinoma.

    2015-08-01

    Adenoid cystic carcinoma (ACC) is a basaloid tumor consisting of myoepithelial and ductal cells typically arranged in a cribriform pattern. Adenoid cystic carcinoma is generally regarded as a form of salivary gland carcinoma, but it can arise from sites unassociated with salivary tissue. A rare form of prostate carcinoma exhibits ACC-like features; it is no longer regarded as a true ACC but rather as prostatic basal cell carcinoma (PBCC) and within the spectrum of basaloid prostatic proliferations. True ACCs often harbor MYB translocations resulting in the MYB-NFIB fusion protein. MYB analysis could clarify the true nature of prostatic carcinomas that exhibit ACC features and thus help refine the classification of prostatic basaloid proliferations. Twelve PBCCs were identified from the pathology consultation files of Johns Hopkins Hospital. The histopathologic features were reviewed, and break-apart fluorescence in situ hybridization for MYB was performed. All 12 cases exhibited prominent basaloid histology. Four were purely solid, 7 exhibited a cribriform pattern reminiscent of salivary ACC, and 1 had a mixed pattern. The MYB rearrangement was detected in 2 (29%) of 7 ACC-like carcinomas but in none (0%) of the 5 PBCCs with a prominent solid pattern. True ACCs can arise in the prostate as is evidenced by the presence of the characteristic MYB rearrangement. When dealing with malignant basaloid proliferations in the prostate, recommendations to consolidate ACCs with other tumor types may need to be reassessed, particularly in light of the rapidly advancing field of biologic therapy where the identification of tumor-specific genetic alterations presents novel therapeutic targets.

  8. Increased percentage of T cells with the expression of CD127 and CD132 in hypertrophic adenoid in children with otitis media with effusion.

    Żelazowska-Rutkowska, Beata; Wysocka, Jolanta; Ratomski, Karol; Kasprzycka, Edwina; Skotnicka, Bożena

    2012-07-01

    The hypertrophic adenoid may promote chronic suppurative otitis media in children as it fulfills its immune function. The number of lymphocytes in the adenoid and their cooperation in the immune response depend of on their proliferation and migration to the effector sites. Interleukin 7 (IL-7) is essential for the normal development and function lymphocytes. IL-7 plays pivotal role for activation and proliferation of T and B cells. The heterodimeric interleukin-7 receptor (IL-7R) is composed of the IL-7Rα (127) and the common cytokine receptor γc (CD132). The aim of this study was to evaluate the percentage of lymphocytes T (CD4(+) and CD8(+)) with IL-7R (CD127 and CD132) expression in hypertrophic adenoid in children suffering with otitis media with effusion for a duration of 3 months. Adenoid excised due to hypertrophy with or without chronic otitis media with effusion was used as study material. CD4(+) CD127(+), CD4(+)132(+), CD8(+)CD127(+) and CD8(+)CD132(+) cell subpopulations were identified using monoclonal antibodies and flow cytometry. The percentage of CD4(+) and CD8(+) T cells with CD127 receptor expression in hypertrophic adenoid of children with otitis media with effusion was statistically significantly higher than in hypertrophic adenoid group. The percentage of CD4(+) T cells with CD132 expression in the study group was statistically significantly higher than in the reference group. The percentage of CD8(+) T cells with CD132(+) expression was not statistically different in both groups. The increased percentage of T lymphocytes with IL-7R expression (CD127 and CD132) in hypertrophic adenoid seems to influence the quantity of lymphocytes and upset the immunological function of tonsils which can influence the course of otitis media with effusion.

    Full Text Available Background: As a part of pre-operative evaluation, several otolaryngologists group and cross-match blood routinely for children undergoing adenoid and tonsil surgeries. This practice has generated several debates either in support or against this practice. The aim of this study is to critically evaluate the incidence of post-tonsillectomy (with or without adenoidectomy bleeding and blood transfusions in otherwise healthy children with adenoid/tonsil pathologies conducted in the University of Port Harcourt Teaching Hospital (UPTH. Patients and Methods: A descriptive retrospective study of children who underwent adenoid and tonsil surgeries in the Department of Ear, Nose and Throat (ENT surgery of UPTH from January 2003 to December 2012. Children with family history of bleeding disorders and derangement of clotting profile as well as different co-morbidity like sickle cell disease were excluded from this study. The patients′ data were retrieved from the registers of ENT out-patient clinics, theatre registers and patients case notes. Demographic data, indications for surgery, preoperative investigations, complications and management outcomes were recorded and analyzed. Results: Out of 145 children that had adenoid and tonsil surgeries; only 100 met the criteria for this study. The study subjects included 65 males and 35 females (male: female ratio 1.9:1 belonging to 0-16 years age group (mean age: 3.46 ± 2.82 years. The age group of 3-5 years had the highest (n = 40, 40% number of surgeries. Adenotonsillectomy was the commonest (n = 85, 85% surgery performed on patients who had obstructive sleep apnea (OSA. The commonest (n = 6, 6% complication was haemorrhage, and only few (n = 3, 3% patients had blood transfusion. However, mortality was recorded in some (n = 3, 3% patients. Conclusion: This study confirms that the incidence of post adenoidectomy/tonsillectomy bleeding in otherwise healthy children is low and rarely requires blood transfusion

    2016-10-01

    A 33-year-old woman presented with an unusual subglottic bulging mass accompanied by prolonged cough and wheeze. Laryngeal endoscopy revealed a bilateral, symmetrical mass immediately below the vocal cords with marked airway obstruction. Chronic subglottic laryngitis with inflammation or another condition such as amyloidosis was initially suspected. Cervicothoracic computed tomography revealed an obvious reduction of laryngeal caliber caused by an engulfing mass extending from just under the vocal cords to the cricoid ring, which was associated with thyroid, arytenoid, and cricoid cartilage destruction. Histopathological diagnosis of a biopsy specimen collected via a tracheotomy revealed that the lesion was a cT4aN0M0 adenoid cystic carcinoma (ACC) originating from the laryngeal minor salivary glands. The patient was treated by total laryngectomy with elective bilateral neck dissection under general anesthesia. Gross inspection of resected tissue confirmed yellowish-white, solid tumor mainly circumferentially encompassing the lumina of the cricoid ring. The histopathological findings confirmed typical ACC accompanied by a predominant cribriform appearance with no evidence of lymph node metastasis. The patient remains well and free of recurrence or metastasis. We herein describe laryngeal ACC and discuss radiological images and the surgical pathology. PMID:26803452

    2009-12-01

    Adenoid cystic carcinoma (AdCC) and polymorphous low-grade adenocarcinoma (PLGA) have several common histological and clinicopathological features that may create diagnostic difficulties. In this study, 10 AdCCs, 8 PLGAs, and 5 normal minor salivary glands as a control group were selected. Sections prepared from each tumor were stained using the streptavidin-biotin system for seven marker antigens: carcinoembryonic antigen (CEA), epithelial membrane antigen (EMA), muscle-specific actin (MSA), vimentin, S100, p53, and Ki-67. Data analysis showed high expression of CEA, MSA and Ki-67 in AdCCs compared with PLGAs, although CEA expression was limited to luminal cells. Ki-67 was expressed in both luminal and non-luminal cells and MSA only in non-luminal cells. Vimentin and S100 showed stronger expression in PLGAs, the expression of vimentin was more noticeable, being focal and widespread. The immunoreactivities of EMA and P53 were not helpful for distinguishing between the two tumors, although the EMA expression pattern in AdCCs was limited to luminal cells, whereas it was present in both luminal and non-luminal cells in PLGAs. Thus, immunohistochemistry can be helpful for differential diagnosis of AdCC and PLGA, particularly that for CEA, vimentin, and Ki-67. PMID:20032601

  14. Pattern of failure and role of radiotherapy in adenoid cystic carcinoma of the head and neck

    This retrospective study reviewed 55 patients with adenoid cystic carcinoma of the head and neck who were treated with radiotherapy for primary sites between 1980 and 1998. The treatment modality consisted of radiotherapy combined with surgery in 44 patients and radiotherapy without surgery in 11. Chemotherapy was also administered to 9 operated and 6 unoperated patients. The range of prescribed doses was 25-65 Gy (median 50 Gy) for patients who underwent surgery, and 60-70 Gy (median 65 Gy) for those who did not. Local failure occurred in 16 patients (29%), and 20 (36%) developed distant metastasis, which were common types of failure. Although not statistically significant different, local relapse free rates of early stage tumors were better than those of advanced stage tumors (p=0.08). The local relapse free rates were influenced by the primary sites (major vs. minor salivary glands) (p=0.04). These factors, however, had no impact on survival. Three patients developed recurrences in the skull base probably thorough perineural spread. Neck failure was also uncommon type of recurrence, occurring in only two patients. We also discuss elective irradiation to the neck nodes and the skull base. (author)

  15. Exclusive irradiation of cyst adenoid carcinomas: contribution of a dose complement in stereotactic mode

    The cyst adenoid carcinoma is a rare malignant tumor that reaches principally the salivary glands; It is characterized by a clinical aggressiveness, the presence of peri neural invasions, frequent local recurrences and a high rate of metastases dissemination at delayed distance. The treatment is surgery with a postoperative adjuvant radiotherapy. for the patients suffering of inoperable tumors, the exclusive radiotherapy gives bad results with tests of use of heavy particles. The place of a hypo fractionated treatment on a stereotactic mode has not been evaluated, especially in dose complement after three dimensional irradiation. The purpose was to answer the following question if the Cyberknife was useful to deliver a complement of hypo fractionated stereotactic dose for the inoperable head and neck tumors. The limited number of patients does not allow a definitive conclusion. however, this therapy option seems interesting for the inoperable tumors subject to the management of the toxicity induced by the treatment. The evaluation of the irradiation volumes remains the critical element for the feasibility of this kind of protocol. (N.C.)

  16. Intracranial extension of adenoid cystic carcinoma of the palate: a case report

    Intracranial involvement by adenoid cystic carcinoma (ACC) is very rare and there is no report of intracranial extension from the palate ACC in Korea. Intracranial involvement can occur in one of three ways: direct extension, perineural spread, and hematogenous spread. A case report of a 35-year-old woman with intracranial ACC is presented. Initially she had ACC of the right palate and was treated by surgery and postoperative radiation therapy. Three years and 10 months later, the paresthesia in the distribution of ophthalmic and maxillary branch of right trigeminal nerve developed without evidence of recurrence in CT scan. Ptosis and total ophthalmoplegia developed sequentially and the second operation was performed. It was suggested that the tumor was spread perineurally along the trigeminal nerve into the Gasserian ganglion and then cavernous sinus and orbit. Seven years and 6 months after the first operation, direct intracranial extension into the right temporal lobe developed via sphenoid bone, sphenoid sinus and temporal bone and the third operation was done. And then Jung metastasis was diagnosed. She is alive for 9 years 5 months after first operation

    Full Text Available INTRODUÇÃO: a hipertrofia de adenoide é uma das principais causas da respiração bucal. Entre os métodos utilizados para o diagnóstico dessa condição, os mais precisos são a endoscopia nasal e a ressonância magnética. No entanto, o método mais utilizado, em Odontologia, é a radiografia cefalométrica lateral. OBJETIVO: determinar a eficácia dessa radiografia no diagnóstico da hipertrofia de adenoide, pela sua comparação com a endoscopia nasal. MÉTODOS: foram avaliados 30 indivíduos (7 a 12 anos. Todos fizeram exame de endoscopia nasal e radiografia cefalométrica lateral. Nas endoscopias, foi registrada a porcentagem de obstrução da nasofaringe e, nas radiografias, a menor dimensão anteroposterior livre da nasofaringe. RESULTADOS: os exames se mostraram fortemente correlacionados (r = - 0,793, p-valor INTRODUCTION: One of the most usual causes of mouth breathing is adenoids hypertrophy with reduction of the nasopharyngeal space. The most precise diagnostic methods are magnetic resonance and nasal endoscopy, because they make possible a three dimension image of the nasopharynx. However, in Dentistry, cephalometric radiography is the method used in the majority of cases. That is why it is so important the evaluation of the efficacy of this diagnostic method.

    Haemophili are pathogenic or opportunistic bacteria often colonizing the upper respiratory tract mucosa. The prevalence of Haemophilus influenzae (with serotypes distribution), and H. parainfluenzae in the nasopharynx and/or the adenoid core in children with recurrent pharyngotonsillitis undergoing adenoidectomy was assessed. Haemophili isolates were investigated for their ability to biofilm production.Nasopharyngeal swabs and the adenoid core were collected from 164 children who underwent adenoidectomy (2-5 years old). Bacteria were identified by the standard methods. Serotyping of H. influenzae was performed using polyclonal and monoclonal antisera. Biofilm formation was detected spectrophotometrically using 96-well microplates and 0.1% crystal violet.Ninety seven percent (159/164) children who underwent adenoidectomy were colonized by Haemophilus spp. The adenoid core was colonized in 99.4% (158/159) children, whereas the nasopharynx in 47.2% (75/159) children (P parainfluenzae and 14 isolates of other Haemophilus spp. were selected. In 20.1% (32/159) children 2 or 3 phenotypically different isolates of the same species (H. influenzae or H. parainfluenzae) or serotypes (H. influenzae) were identified in 1 child. 67.2% (129/192) isolates of H. influenzae, 56.3% (54/96) isolates of H. parainfluenzae and 85.7% (12/14) isolates of other Haemophilus spp. were positive for biofilm production. Statistically significant differences (P = 0.0029) among H. parainfluenzae biofilm producers and nonproducers in the adenoid core and the nasopharynx were detected.H. influenzae and H. parainfluenzae carriage rate was comparatively higher in the adenoid core than that in the nasopharynx in children undergoing adenoidectomy, suggesting that their involvement in chronic adenoiditis. The growth in the biofilm seems to be an important feature of haemophili colonizing the upper respiratory tract responsible for their persistence. PMID:25950686

    2000-01-01

    Objective To study the effects of P53, PCNA, Bcl-2 protein and their relationship in salivary adenoid cystic carcinoma(SACC). Methods These proteins were examined by immunohistochemistry. Results Overexpressions of P53 and PCNA were revealed in ACC samples, they were higher than those in (polymorphous adenomas) PA, but expression of Bcl-2 protein was not different between ACC and PA. In 3 subtypes of ACC, expressions of 3 proteins were different. Conclusion Mutations of P53, Bcl-2 may be involed in the occurrence of SACC, expression of PCNA and mutation of P53 may coexist in the development of the SACC.

  1. Management of Adenoid Cystic Carcinoma of the Breast: A Rare Cancer Network Study

    Background: Mammary adenoid cystic carcinoma (ACC) is a rare breast cancer. The aim of this retrospective study was to assess prognostic factors and patterns of failure, as well as the role of radiation therapy (RT), in ACC. Methods: Between January 1980 and December 2007, 61 women with breast ACC were treated at participating centers of the Rare Cancer Network. Surgery consisted of lumpectomy in 41 patients and mastectomy in 20 patients. There were 51(84%) stage pN0 and 10 stage cN0 (16%) patients. Postoperative RT was administered to 40 patients (35 after lumpectomy, 5 after mastectomy). Results: With a median follow-up of 79 months (range, 6–285), 5-year overall and disease-free survival rates were 94% (95% confidence interval [CI], 88%–100%) and 82% (95% CI, 71%–93%), respectively. The 5-year locoregional control (LRC) rate was 95% (95% CI, 89%–100%). Axillary lymph node dissection or sentinel node biopsy was performed in 84% of cases. All patients had stage pN0 disease. In univariate analysis, survival was not influenced by the type of surgery or the use of postoperative RT. The 5-year LRC rate was 100% in the mastectomy group versus 93% (95% CI, 83%–100%) in the breast-conserving surgery group, respectively (p = 0.16). For the breast-conserving surgery group, the use of RT significantly correlated with LRC (p = 0.03); the 5-year LRC rates were 95% (95% CI, 86%–100%) for the RT group versus 83% (95% CI, 54%–100%) for the group receiving no RT. No local failures occurred in patients with positive margins, all of whom received postoperative RT. Conclusion: Breast-conserving surgery is the treatment of choice for patients with ACC breast cancer. Axillary lymph node dissection or sentinel node biopsy might not be recommended. Postoperative RT should be proposed in the case of breast-conserving surgery.

    2010-01-01

    Full Text Available Context: Adenoid cystic carcinoma (ACC is a rare neoplasm that usually arises from the salivary, lacrimal, or other exocrine glands. It is characteristically locally infiltrative in nature and has a tendency toward local recurrence, high propensity for perineural invasion, and prolonged clinical course. Aim: To analyze the presentation and natural history of cases of adenoid cystic tumors of salivary glands in our institution; and to compare with the existing literature. Design and Setting: Retrospective study at the Department of Radiotherapy. Materials and Methods: Data on 18 patients of ACC of the salivary glands treated between 2004 and 2008 were reviewed with respect to clinical presentation, stage, and histology. Results: There were 8 cases of major salivary gland tumors (47%, of which 2 were in the submandibular and 6 were involving the parotid. Ten patients (53% had minor salivary gland involvement. Two patients had metastasis at the time of presentation. All patients underwent surgery. Radiotherapy was delivered to 16 patients and chemotherapy to 6 patients (concurrent, n = 3 and adjuvant, n = 3 and no adjuvant therapy was given to 2 patients. All patients were alive at a median follow-up of 3 years. No patient developed local or distant failure during the study duration. Conclusion: ACC has locally aggressive behavior. Radiotherapy adjuvant to surgery improves local control in locally advanced disease. Longer follow-up is mandatory in view of incidence of late metastasis.

  4. Adenoid cystic carcinoma of the parotid gland: Anastamosis of the facial nerve with the great auricular nerve after radical parotidectomy

    Bahadir Osman

    2008-01-01

    Full Text Available Adenoid cystic carcinoma of the parotid gland is a rare and slowly growing, but highly malignant tumor. Surgical resection of a malignant parotid tumor should include resection of the facial nerve when the nerve is involved in the tumor. Facial nerve reconstruction is required after nerve resection. A 14 year-old female presented with complaints of painless enlargement of the right parotid gland and facial asymmetry. Physical examination revealed a firm mass in the region of the parotid gland as well as right facial paralysis. Biopsy obtained from the mass showed an adenoid cystic carcinoma of the parotid gland. A radical parotidectomy with a modified radical neck dissection was carried out. Grafting material for the facial reconstruction was harvested from the great auricular nerve. The proximal main trunk and each distal branch of the facial nerve were coapted with the greater auricular nerve. The patient received radiotherapy after surgery and was seen to achieve grade IV facial function one year after surgery. Thus, the great auricular nerve is appropriate grafting material for coaptation of each distal branch of the facial nerve.

  5. Reactive oxygen species and autophagy associated apoptosis and limitation of clonogenic survival induced by zoledronic acid in salivary adenoid cystic carcinoma cell line SACC-83.

    Xi-Yuan Ge

    Full Text Available Salivary adenoid cystic carcinoma is an epithelial tumor in the head and neck region. Despite its slow growth, patients with salivary adenoid cystic carcinoma exhibit poor long term survival because of a high rate of distant metastasis. Lung and bone are common distant metastasis sites. Zoledronic acid, a third generation bisphosphonate, has been used for tumor-induced osteolysis due to bone metastasis and has direct antitumor activity in several human neoplasms. Here, we observed that zoledronic acid inhibited salivary adenoid cystic carcinoma cell line SACC-83 xenograft tumor growth in nude mice. In vitro, zoledronic acid induced apoptosis and reduced clonogenic survival in SACC-83. Flow cytometry and western blotting indicated that the cell cycle was arrested at G0/G1. Zoledronic acid treatment upregulated reactive oxygen species as well as the autophagy marker protein LC-3B. Reactive oxygen species scavenger N-acetylcysteine and autophagy antagonist 3-methyladenine decreased zoledronic acid-induced apoptosis and increased clonogenic survival. Silencing of the autophagy related gene Beclin-1 also decreased zoledronic acid-induced apoptosis and inhibition of clonogenic formation. In addition, isobolographic analysis revealed synergistic effects on apoptosis when zoledronic acid and paclitaxel/cisplatin were combined. Taken together, our results suggest that zoledronic acid induced apoptosis and reduced clonogenic survival via upregulation of reactive oxygen species and autophagy in the SACC-83 cell line. Thus, zoledronic acid should be considered a promising drug for the treatment of salivary adenoid cystic carcinoma.

    Background Due to the rarity of adenoid cystic carcinoma (ACC), information on outcome is based upon small retrospective case series. The aim of our study was to create a large multiinstitutional international dataset of patients with ACC in order to design predictive nomograms for outcome. Methods ACC patients managed at 10 international centers were identified. Patient, tumor, and treatment characteristics were recorded and an international collaborative dataset created. Multivariable competing risk models were then built to predict the 10 year recurrence free probability (RFP), distant recurrence free probability (DRFP), overall survival (OS) and cancer specific mortality (CSM). All predictors of interest were added in the starting full models before selection, including age, gender, tumor site, clinical T stage, perineural invasion, margin status, pathologic N-status, and M-status. Stepdown method was used in model selection to choose predictive variables. An external dataset of 99 patients from 2 other institutions was used to validate the nomograms. Findings Of 438 ACC patients, 27.2% (119/438) died from ACC and 38.8% (170/438) died of other causes. Median follow-up was 56 months (range 1–306). The nomogram for OS had 7 variables (age, gender, clinical T stage, tumor site, margin status, pathologic N-status and M-status) with a concordance index (CI) of 0.71. The nomogram for CSM had the same variables, except margin status, with a concordance index (CI) of 0.70. The nomogram for RFP had 7 variables (age, gender, clinical T stage, tumor site, margin status, pathologic N status and perineural invasion) (CI 0.66). The nomogram for DRFP had 6 variables (gender, clinical T stage, tumor site, pathologic N-status, perineural invasion and margin status) (CI 0.64). Concordance index for the external validation set were 0.76, 0.72, 0.67 and 0.70 respectively. Interpretation Using an international collaborative database we have created the first nomograms which

    Adenoid cystic carcinoma (ACC) is both invasive and clinically unpredictable, and our aim was to evaluate the factors that affect its recurrence in the palate. We retrospectively studied 38 patients who had ACC of the palate treated surgically, and the outcome measure was recurrence during the mean (SD) followup time of 55 (18) months. Age, sex, T-stage, bony involvement, duration of follow up, histological type, perineural invasion, and surgical margins were all recorded. Results showed no association between recurrence, and age or histopathological types. However, T-stage (p=0.001), sex (p=0.04), and bony and perineural involvement (p=0.01 in each case) were significantly associated with recurrent tumour. Close superior and posterior margins (< 2mm) were also associated with recurrence (p=0.001 in each case). Large tumours with bony and perineural involvement, together with close superior and posterior surgical margins, had a higher risk of recurrence. PMID:27094499

  10. An unusual presentation of adenoid cystic carcinoma of the minor salivary glands with cranial nerve palsy: a case study

    Adenoid Cystic Carcinoma (ACC) is a rare tumor entity and comprises about 1% of all malignant tumor of the oral and maxillofacial region. It is slow growing but a highly invasive cancer with a high recurrence rate. Intracranial ACC is even more infrequent and could be primary or secondary occurring either by direct invasion, hematogenous spread, or perineural spread. We report the first case of the 5th and 6th nerve palsy due to cavernous sinus invasion by adenoid cystic carcinoma. A 49-year-old African American female presented to the emergency room complaining of severe right-sided headache, photophobia, dizziness and nausea, with diplopia. The patient had a 14 year history migraine headaches, hypertension, and mild intermittent asthma. Physical examination revealed right lateral rectus muscle palsy with esotropia. There was numbness in all three divisions of the right trigeminal nerve. Motor and sensory examination of extremities was normal. An MRI of the brain/brain stem was obtained which showed a large mass in the clivus extending to involve the nasopharynx, pterygoid plate, sphenoid and right cavernous sinuses. Biopsy showed an ACC tumor with a cribriform pattern of the minor salivary glands. The patient underwent total gross surgical resection and radiation therapy. This is a case of ACC of the minor salivary glands with intracranial invasion. The patient had long history of headaches which changed in character during the past year, and symptoms of acute 5th and 6th cranial nerve involvement. Our unique case demonstrates direct invasion of cavernous sinus and could explain the 5th and 6th cranial nerve involvement as histopathology revealed no perineural invasion

  12. [The tonsils and adenoids as a site of infection and the cause of obstruction].

    Battistini, A; Siepe, F; Marvasi, R

    1998-01-01

    The failure to eradicate group A beta-hemolytic streptococci from the pharynx is partly due to a low compliance, but above all, an alteration of the oropharyngeal microbiological flora: reduction of alpha-haemolytic streptococci which inhibit group A beta-hemolytic streptococci and increase of microorganisms such as Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis. These latter act indirectly destroying the beta-lactamic ring of penicillins. However, this obstacle is overcome by the use of antibiotics which do not contain beta-lactamic rings such as macrolides or associating amoxicillin with clavulanic acid or with new cephalosporins which are more resistant to beta lactamases. To restrict the diffusion of resistance to antibiotics, it is essential to limit their use diagnosing streptococcal tonsillopharyngitis more precisely, thanks to an improved use of micro-biological diagnostic tests and by a more extended use of tonsillectomy in recurrent tonsillitis (more than 6-7 in 1-2 years). Adenoiditis is closely related to the post nasal drip syndrome, to recurrent otitis media and to otitis media with effusion. All these situations could, therefore, represent an indication, although not well defined, for adenoidectomy. Nasopharyngeal obstruction due to adeno-tonsillar hypertrophy becomes critical during sleep when the hypotony of the upper airway muscles becomes additional to the anatomical obstruction. At this point the inspiratory effort required and the consequent decrease of intra airway pressure increase the pharyngeal obstruction suctioning the pharyngeal walls toward the median line. The resulting clinical picture is defined as sleep-disordered breathing (SDB) due to adenotonsillar hypertrophy (idiopathic), to be distinguished from SDB due to cranio-facial abnormalities or neuromuscular diseases. SDB includes both the more serious sleep apnea syndrome and the less severe upper airway respiratory resistance syndrome. A combination of

  15. 125I brachytherapy alone for recurrent or locally advanced adenoid cystic carcinoma of the oral and maxillofacial region

    Background and purpose: This retrospective study was to evaluate the local control and survival of 125I brachytherapy for recurrent and/or locally advanced adenoid cystic carcinoma (ACC) of the oral and maxillofacial region. Patients and methods: A total of 38 patients with recurrent and/or locally advanced ACC of the oral and maxillofacial region received 125I brachytherapy alone from 2001-2010. Twenty-nine were recurrent cases following previous surgery and radiation therapy. The other 9 cases involved primary tumors. Overall, 12 tumors were located in the major salivary glands, 12 in the minor salivary glands, and 14 in the paranasal region, the nasal cavity or the skull base. The prescribed dose was 100-160 Gy. Results: Patients were followed for 12-122 months (median 51 months). The 2-, 5-, and 10-year local tumor control rates were 86.3, 59, and 31.5 %, respectively. The 2-, 5-, and 10-year overall survival rates were 92.1, 65 and 34.1 %, respectively. Tumors > 6 cm had significantly lower local control and survival rates. No severe complications were observed during follow-up. Conclusion: 125I brachytherapy is a feasible and effective modality for the treatment of locally advanced unresectable or recurrent ACC.

  17. Effects of 5-aza-2′deoxycytidine on RECK gene expression and tumor invasion in salivary adenoid cystic carcinoma

    Reversion-inducing cysteine-rich protein with kazal motifs (RECK), a novel tumor suppressor gene that negatively regulates matrix metalloproteinases (MMPs), is expressed in various normal human tissues but downregulated in several types of human tumors. The molecular mechanism for this downregulation and its biological significance in salivary adenoid cystic carcinoma (SACC) are unclear. In the present study, we investigated the effects of a DNA methyltransferase (DNMT) inhibitor, 5-aza-2′deoxycytidine (5-aza-dC), on the methylation status of the RECK gene and tumor invasion in SACC cell lines. Methylation-specific PCR (MSP), Western blot analysis, and quantitative real-time PCR were used to investigate the methylation status of the RECK gene and expression of RECK mRNA and protein in SACC cell lines. The invasive ability of SACC cells was examined by the Transwell migration assay. Promoter methylation was only found in the ACC-M cell line. Treatment of ACC-M cells with 5-aza-dC partially reversed the hypermethylation status of the RECK gene and significantly enhanced the expression of mRNA and protein, and 5-aza-dC significantly suppressed ACC-M cell invasive ability. Our findings showed that 5-aza-dC inhibited cancer cell invasion through the reversal of RECK gene hypermethylation, which might be a promising chemotherapy approach in SACC treatment

    Jovičić-Milentijević Maja

    2011-01-01

    Full Text Available Background. We presented an unusual case of adenoid cystic carcinoma (ACC of the breast with multinucleated stromal giant cells (MSGCs. To the best of our knowledge, the occurrence of ACC with MSGCs has not been reported previously. MSGCs should be distinguished from other multinucleated giant cells in breast tumors. The histogenesis of MSGCs still remains obscure. In hope to elucidate the histogenesis of MSGCs, we used a broad range of antibodies. Case report. A 40-year-old woman presented with a palpable lump in the subareolar location of her right breast. Excision of the tumor was performed. At gross pathologic examination the tumor was 20 × 15 × 15 mm in size, redbrown and well circumscribed. The surgical margins were positive for carcinoma and skin-sparing mastectomy with axillary dissection was complited. Eighteen lymph nodes examined were uninvolved. Patohistological examination showed ACC with numerous MSGCs scattered within tumor stroma. Immunohistochemical studies indicated that MSGCs are probably derived from stromal fibroblasts. These cells showed strong reactivity only for vimentin. Staining for histiocytic marker (CD68, as well as for epithelial marker (cytokeratin, myoepithelial markers (S-100, α- smooth muscle actin, vascular marker (CD34, hormonal receptors (ER, PR and HER2 in MSGCs were negative. Conclusion. The presence of MSGCs should not alter the prognosis of an otherwise typical breast ACC.

    Full Text Available Background: Adenoid cystic carcinoma (ACC accounts for 1% of all head and neck (HN cancers. Materials and Methods: Demographic, clinical, treatment, and survival details of 66 patients were collected (1995-2011 and analyzed. Disease-free survival (DFS was estimated by Kaplan-Meier method. Results: Primary disease sites were sinonasal (n = 27, salivary gland (n = 30, and others (n = 9. Median follow-up was 23 months (range: 12-211 months. Estimated DFS at 2- and 5-year were 75% and 67.2%, respectively. On univariate analysis, intra-cranial extension (ICE (hazard ratio [HR]: 3.59, P = 0.0071, lymph node involvement (HR: 4.05, P = 0.0065, treatment modality (others vs. surgery plus adjuvant radiotherapy, HR: 2.39, P = 0.0286 and T stage (T3/4 vs. T1/2, HR: 3.27, P = 0.007 had significant impact on DFS. Lymph node involvement (P = 0.038 and ICE (P = 0.038 continued to have significant impact on DFS on multivariate analysis. Conclusion: Surgery followed by adjuvant radiotherapy remains the treatment of choice for HN ACC. Lymph node involvement and ICE confer poor prognosis.

    Adenoid cystic carcinoma (SACC) is a rare malignancy, but a frequent subtype in minor and major salivary glands. The molecular alterations or biomarkers that underlie its development and progression as well as therapy outcomes are poorly characterized. The main study goal was to investigate reliable biomarkers and patient-related factors that may have impact on recurrence and long-term survival of SACC. The prevalence of human papilloma virus (HPV) in SACC was determined by HPV-DNA genotyping and p16 immunostaining. Epithelial growth factor receptor (EGFR), p53 and Ki-67 expression were also evaluated. Twenty-eight (42%) of 67 patients were HPV-DNA positive. Kaplan-Meier analysis indicated that SACC patients with metastases (P=0.03) had a poor overall survival (OS) and a shorter recurrence-free survival (POS while non-metastatic disease (P=0.002), HPV positivity (P=0.041) and negative resection margin predicted a better recurrence-free survival. The present study documents for the first time the positivity for HPV infection and overexpression of certain markers (p16, Ki-67, EGFR and p53) used in diagnostics in SACC as well as characterizes clinical entities. These factors might be exploited in the future as biomarkers for its prognostic value. Using the clinical and pathological basis for predicting different outcomes could significantly facilitate SACC stratification and potentially directing treatment. PMID:27279281

    Full Text Available Abstract Objectives This study consisted of two parts. One part was to analyze the survival rates of adenoid cystic carcinoma (ACC in Chinese and explain the difference between our data and the literature. The other was to analyze the relationship between the expression of CD117 and the histological grade and the prognosis. Methods A retrospective study of 80 ACC patients was performed. Clinical data were collected, and p63, CD117 were detected by immunohistochemical staining. Results Eighty patients received follow-ups 3 to 216 months after initial diagnosis. ACC occurred in the lacrimal gland (26.3%, n = 21, nasal cavity and parasinus (33.8%, n = 27 and other sites (40.0%, n = 33. The 5-year and 10-year survival rates were 66.41% and 10.16%, respectively. Over expression of CD117 was detected in p63-negative cells in 94.3% of cases and in p63-positive cells in 45.8%. The expression of CD117 in p63-positive cells was significantly associated with the histological grade (P Conclusions ACC had a good 5-year survival but poor 10-year survival in Chinese, which differed from the occidental data. More p63+/CD117+ cells were associated with a higher histological grade and poorer outcome.

The invasive ability of SACC cells was examined by the Transwell migration assay. Promoter methylation was only found in the ACC-M cell line. Treatment of ACC-M cells with 5-aza-dC partially reversed the hypermethylation status of the RECK gene and significantly enhanced the expression of mRNA and protein, and 5-aza-dC significantly suppressed ACC-M cell invasive ability. Our findings showed that 5-aza-dC inhibited cancer cell invasion through the reversal of RECK gene hypermethylation, which might be a promising chemotherapy approach in SACC treatment.

    2010-11-01

    Full Text Available Abstract Background Local control in adjuvant/definitive RT of adenoid cystic carcinoma (ACC is largely dose-dependent. However, some clinical situations do not allow application of tumouricidal doses (i.e. re-irradiation hence radiation sensitization by exploitation of high endothelial growth factor receptor (EGFR-expression in ACC seems beneficial. This is a single-institution experience of combined radioimmunotherapy (RIT with the EGFR-inhibitor cetuximab. Methods Between 2006 and 2010, 9 pts received RIT for advanced/recurrent ACC, 5/9 pts as re-irradiation. Baseline characteristics as well as treatment parameters were retrieved to evaluate efficacy and toxicity of the combination regimen were evaluated. Control rates (local/distant and overall survival were calculated using Kaplan-Meier estimation. Results Median dose was 65 Gy, pts received a median of 6 cycles cetuximab. RIT was tolerated well with only one °III mucositis/dysphagia. Overall response/remission rates were high (77,8%; 2-year estimate of local control was 80% hence reaching local control levels comparable to high-dose RT. Progression-free survival (PFS at 2 years and median overall survival were only 62,5% and 22,2 mo respectively. Conclusion While local control and treatment response in RIT seems promising, PFS and overall survival are still hampered by distant failure. The potential benefit of RIT with cetuximab warrants exploration in a prospective controlled clinical trial.

  5. Efficacy of sorafenib, a multi-tyrosine kinase inhibitor, in an adenoid cystic carcinoma metastatic to the lung: case report and review of literature

    Santos Edgardo S

    2011-09-01

    Full Text Available Abstract Introduction Treatment for squamous cell carcinoma of the head and neck has significantly improved with the addition of cetuximab, a monoclonal antibody against the epidermal growth factor receptor, to conventional cytotoxic agents. The most significant aspect of this treatment approach is the proof that head and neck cancers are suitable for targeted therapies as has been shown in other malignancies. Unfortunately, there are other rare histologic types of head and neck cancer such as adenocarcinoma and adenoid cystic carcinoma. The latter has traditionally been considered to be chemotherapy resistant and surgical resection with or without adjuvant radiation therapy has been the rule as far as treatment is concerned. The course of adenoid cystic carcinoma ranges from indolent to aggressive; however, most patients succumb to the disease as a result of distant metastases. This clinical scenario poses a challenge to oncologists. Several conventional chemotherapy regimens and novel targeted agents have been tried in this rare histologic subtype without success. Case presentation In this case report, we present a 59-year-old Caucasian female with refractory adenoid cystic carcinoma of the maxilla metastatic to the lung that responded to sorafenib, a novel multi-tyrosine kinase inhibitor, which targets angiogenesis, Raf kinase pathway, platelet-derived growth factor Ret, and c-Kit. Conclusion This case illustrates the possibility that this chemoresistant tumor may need the inhibition or blocking of several oncogenic pathways. Certainly, it is imperative that more studies are done in this special population trying to identify tumorigenesis mechanisms that may be upregulated in this malignancy and could be potential targets for therapeutic development.

  7. Bmi-1 expression predicts prognosis in salivary adenoid cystic carcinoma and correlates with epithelial-mesenchymal transition-related factors.

    Yi, Chun; Li, Bin-Bin; Zhou, Chuan-Xiang

    2016-06-01

    Salivary adenoid cystic carcinoma (AdCC) is known for its high propensity to invade and metastasize. Bmi-1 acts as an oncogene by controlling cell cycle and self-renewal of adult stem cells, and its overexpression correlates with metastasis and poor prognosis in several cancers. Epithelial-mesenchymal transition (EMT) plays a central role in cancer metastasis. A key step in EMT is the down-regulation of E-cadherin that can be repressed by the transcriptional factors, such as Snail and Slug. In the present study, we investigated Bmi-1, Snail, Slug, and E-cadherin expression by immunohistochemistry in 102 patients with AdCC and analyzed statistically whether their expression correlated with clinicopathologic factors and prognosis. Reverse transcription-polymerase chain reaction was also performed in 22 tumor tissues and the adjacent noncancerous tissues to confirm Bmi-1 status in AdCCs. Our data demonstrated significant associations between the tumor metastasis and the expression of Bmi-1, Snail, Slug, and E-cadherin. Furthermore, a high level of Bmi-1 was not only correlated with the overexpression of Snail and Slug but also indicated an unfavorable metastasis-free survival and served as a high-risk marker for AdCC. In addition, Bmi-1 messenger RNA level was found much higher in AdCC tissues than in the adjacent noncancerous salivary gland tissues. Our results suggest that Bmi-1 may play a crucial role in AdCC progression by interaction with EMT-related markers and predict poor survival. PMID:27180058

  8. Therapeutic strategies for adenoid cystic carcinoma of the nasal and paranasal sinus from the long-term treatment results

    This article presents long-term treatment results by analyzing 24 cases with adenoid cystic carcinoma (ACC) of the nasal and paranasal sinus treated from 1975 to 1995 at Akita University Hospital and Chiba University Hospital. The basic strategies for treatment for ACC of the nasal and paranasal sinuses are en bloc tumor resection, followed by primary reconstruction of the maxilla. Preoperative and postoperative radiation were combined. Cumulative 5-year and 10-year survival rates were 70.6% and 47.1% for maxillary sinus tumors, respectively. Cumulative 5-year and 10-year survival rates for nasal tumors were 100% and 75.0%, and those for sphenoid sinus tumors were 50.0% and 0%, respectively. The patient with ethomoid sinus who needed skull base surgery is alive at 8.1 years after therapy. Treatment results closely correlated with tumor extension. Cumulative 5-year survival rates for T2, T3 and, T4 patients with maxillary sinus tumors were 85.7%, 71.4%, and 33.3%, respectively. And cumulative 10-year survival rates for T2, T3, and T4 were 71.4%, 42.9%, and 0%, respectively. The histopathological effects of preoperative radiation were Shimosato II a in 6 out of 10 patients, II b in 2, and III in 2, respectively. Only fast neutron therapy reached Shimosato III. Two of the patients with Shimosato II a died of distant metastasis. The above data suggests that, although radiation therapy alone cannot cure tumors, preoperative full-dose radiation may prevent the development of distant metastasis if it can achieve histopathological effects of a higher classification than Shimosato II b. Because chemotherapy and radiation is not very effective on ACC, the role of skull base surgeries for nasal-paranasal sinus malignancies that invade the skull base is valuable, particularly in cases having a relatively small mass in the ethmoid sinus.

Primary adenoid cystic carcinoma (PACC is an uncommon neoplastic disorder; hence improvements in the description of this disease are needed. Materials and Methods: This is a retrospective clinical study based on all consecutive patients with pathological diagnoses of PACC seen at the NIRD between January 1, 2000 and December 31, 2009. Results: We identified 9 cases of PACC (67% female out of a total of 2,634 patients with lung cancer seen during the period analyzed. The mean age of those 9 patients was 41 years (IQR 36-57, and the frequency of PACC at our center was 0.3%. It is important to note that 67% of those patients had a history of smoking and that 6 of the 9 had the antecedent of previous exposure to biomass fuel smoke. Baseline arterial blood gas analyses revealed a median of 61 mmHg for pO 2 and 28.5 mmHg for pCO 2 . Median FVC was 78%, while FEV 1 was 77% with an FEV 1 /FVC ratio of 78. Death occurred in 56% of cases, and the median survival time was 17 months (IQR 6-26 after the initial diagnosis. Conclusions: The frequency of tracheobronchial PACC among patients with lung cancer was similar to that previously reported (0.3%. According to our results, lung function has no specific phenotype in this disease; however, some abnormalities could be related to potential risk factors such as tobacco use and exposure to biomass fuel smoke.

    The purpose of this study was to suggest general guidelines in the management of the N0 neck of oral cavity and oropharyngeal adenoid cystic carcinoma (AdCC) in order to improve the survival of these patients and/or reduce the risk of neck recurrences. The incidence of cervical node metastasis at diagnosis of head and neck AdCC is variable, and ranges between 3% and 16%. Metastasis to the cervical lymph nodes of intraoral and oropharyngeal AdCC varies from 2% to 43%, with the lower rates pertaining to palatal AdCC and the higher rates to base of the tongue. Neck node recurrence may happen after treatment in 0-14% of AdCC, is highly dependent on the extent of the treatment and is very rare in patients who have been treated with therapeutic or elective neck dissections, or elective neck irradiation. Lymph node involvement with or without extracapsular extension in AdCC has been shown in most reports to be independently associated with decreased overall and cause-specific survival, probably because lymph node involvement is a risk factor for subsequent distant metastasis. The overall rate of occult neck metastasis in patients with head and neck AdCC ranges from 15% to 44%, but occult neck metastasis from oral cavity and/or oropharynx seems to occur more frequently than from other locations, such as the sinonasal tract and major salivary glands. Nevertheless, the benefit of elective neck dissection (END) in AdCC is not comparable to that of squamous cell carcinoma, because the main cause of failure is not related to neck or local recurrence, but rather, to distant failure. Therefore, END should be considered in patients with a cN0 neck with AdCC in some high risk oral and oropharyngeal locations when postoperative RT is not planned, or the rare AdCC-high grade transformation.

    Full Text Available Objective: The aim of the present study was to investigate the demographic and pathological aspects of adenoid cystic carcinomas (ACC in an Iranian sample based on a 20-year archive review.Materials and Methods: In this descriptive study, tumors of the head and neck registered between 1980 and 2000 were evaluated and cases of ACC were selected. Patients’ medical records and pathology reports were reviewed. Variables such as age, sex, duration of disease,symptoms, site of tumor involvement and tumor diameter as well as pathologic features were recorded. Analysis was performed using chi-square and t-tests; P<0.05 was considered as the level of significance.Results: ACC was the most common malignant tumor followed by mucoepidermoid carcinoma and adenocarcinoma NOS. A total of 120 ACCs were found, of which 50.8% occurred in females and 49.2% in males. Patients’ ages ranged from 5 to 90 with a mean of 49.2 (SD=15.9 years. In 60.9% of cases, minor salivary glands were involved and the palate was the most common site. The greatest tumor diameter was between 2-15cm with a mean of 4.6 cm (SD=2.9. The most prevalent histologic appearance was cribriform, followed by tubular pattern. No significant relation was observed between lymph node metastasisand patients’ age, sex, disease duration, greatest tumor diameter and site of involvement.Conclusion: Our findings were relatively similar to other reports from different parts of the world. Further analytic and case-control studies are recommended to gain a better understanding of different aspects of ACC.

  12. Epithelial mesenchymal transition is required for acquisition of anoikis resistance and metastatic potential in adenoid cystic carcinoma.

    Jun Jia

    Full Text Available Human adenoid cystic carcinoma (ACC is characterized by diffused invasion of the tumor into adjacent organs and early distant metastasis. Anoikis resistance and epithelial mesenchymal transition (EMT are considered prerequisites for cancer cells to metastasize. Exploring the relationship between these processes and their underlying mechanism of action is a promising way to better understand ACC tumors. We initially established anoikis-resistant sublines of ACC cells; the variant cells revealed a mesenchymal phenotype through Slug-mediated EMT-like transformation and displayed enhanced metastatic potential both in vitro and in vivo. Suppression of EMT by knockdown of Slug significantly impaired anoikis resistance, migration, and invasion of the variant cells. With overexpression of Slug and Twist, we determined that induction of EMT in normal ACC cells could prevent anoikis, albeit partially. These findings strongly suggest that EMT is indispensable in anoikis resistance, at least in ACC cells. Furthermore, we found that the EGFR/PI3K/Akt pathway acts as the common regulator for EMT-like transformation and anoikis resistance, as confirmed by their specific inhibitors. Gefitinib and LY294003 restored the sensibilities of anoikis-resistant cells to anoikis and simultaneously impaired their metastatic potential. In addition, the results from our in vivo model of metastasis suggest that pretreatment with gefitinib promotes mouse survival by alleviating pulmonary metastasis. Most importantly, immunohistochemistry of human ACC specimens showed a correlation between the overexpression of Slug and EGFR staining. This study has demonstrated that Slug-mediated EMT-like transformation is required by human ACC cells to achieve anoikis resistance and their metastatic potential. Targeting the EGFR/PI3K/Akt pathway holds potential as a preventive strategy against distant metastasis of ACC.

  13. Interdisciplinary treatment of the patient with adenoid cystic carcinoma of the Bartholin’s gland resulting in 15 years’ survival: a case report and review of literature

    2014-11-01

    Full Text Available Carcinoma of the Bartholin’s gland is very rare, comprises below 2% of Bartholin’s gland lesions and adenoid cystic carcinoma (ADC is one of the most uncommon variants and accounts for 10-15% of Bartholin’s gland malignancies. There is no consensus on treatment of ADC of the Bartholin’s gland: reported cases were treated with local excision or vulvectomy with or without lymphadenectomy followed or not by radiotherapy. The survival of patients varies significantly, so we present a case of interdisciplinary treatment of ADC resulting in 15 years’ survival. The patient was initially treated with local excision, but the margins were not clear. Then vulvectomy, inguinal lymphadenectomy and adjuvant brachytherapy were performed resulting in 7 years free of the disease. Relapses were excised by abdominoperineal amputation of the rectum and distal part of the vagina with sigmoideostomy, excisions of local recurrences in vagina and metastasectomy of isolated lung metastases. The patient died manifesting multiple lung metastases 15 years after the initial diagnosis. Based on our experience and world literature, in cases of adenoid cystic carcinoma of the Bartholin’s gland, vulvectomy with or without lymphadenectomy should be considered as a treatment of choice and in patients with positive margin, surgery should be extended by adjuvant radiotherapy.

    2011-02-01

    Full Text Available Abstract Background Local control in adjuvant/definitive RT of adenoid cystic carcinoma (ACC is largely dose-dependent leading to the establishment of particle therapy in this indication. However, even modern techniques leave space for improvement of local control by intensification of local treatment. Radiation sensitization by exploitation of high EGFR-expression in ACC with the EGFR receptor antibody cetuximab seems promising. Methods/design The ACCEPT trial is a prospective, mono-centric, phase I/II trial evaluating toxicity (primary endpoint: acute and late effects and efficacy (secondary endpoint: local control, distant control, disease-free survival, overall survival of the combined treatment with IMRT/carbon ion boost and weekly cetuximab in 49 patients with histologically proven (≥R1-resected, inoperable or Pn+ ACC. Patients receive 18 GyE carbon ions (6 fractions and 54 Gy IMRT (2.0 Gy/fraction in combination with weekly cetuximab throughout radiotherapy. Discussion The primary objective of ACCEPT is to evaluate toxicity and feasibility of cetuximab and particle therapy in adenoid cystic carcinoma.

    2006-03-01

    Full Text Available The purpose of this research was to study the growth of the nasopharynx and adenoid development. Lateral cephalometric radiographs obtained from 320 white Brazilian subjects between 4 and 16 years of age were used. All the participants were nose breathers and none of them had previously undergone adenoidectomy. Tracings were made from the radiographs and cephalometric measurements were performed. The results showed that adenoid sagital thickness is larger in the age group 4 - 5 years and decreases progressively. There is a slight increase in the age group 10 - 11 years, but afterwards the decrease continues. However, the nasopharyngeal free airway space does not decrease in the age group 10 - 11 years, despite the increasing thickness of the adenoid. This is attributable to the downward displacement of the hard palate, resulting in an increase of the free airway space due to growth. Although the nasopharynx follows a growth pattern similar to that of the rest of the body, adenoid tissue does not. Adenoidal development seems to differ from that of other lymphatic tissues, showing a peculiar pattern that can be revealed when hypertrophy due to infections and allergies is eliminated.O objetivo da pesquisa foi estudar o crescimento da nasofaringe e o desenvolvimento da adenóide. Foram utilizadas as radiografias cefalométricas de perfil obtidas de 320 indivíduos brasileiros brancos, cujas idades variavam entre 4 e 16 anos. Todos os participantes apresentavam respiração predominantemente nasal e não haviam sido submetidos previamente à adenoidectomia. A partir das radiografias foram feitos traçados cefalométricos, sobre os quais foram realizadas medições. Os resultados revelaram que a espessura sagital da adenóide é maior na faixa etária de 4 a 5 anos, regredindo, então, progressivamente, até a faixa etária de 10 a 11 anos, quando ocorre um leve aumento, voltando a diminuir em seguida.

    Salivary gland adenoid cystic carcinoma (ACC) is a rare head and neck malignancy without molecular biomarkers that can be used to predict the chemotherapeutic response or prognosis of ACC. The regulation of gene expression of oncogenes and tumor suppressor genes (TSGs) through DNA promoter methylation may play a role in the carcinogenesis of ACC. To identify differentially methylated genes in ACC, a global demethylating agent, 5-aza-2′-deoxycytidine (5-AZA) was utilized to unmask putative TSG silencing in ACC xenograft models in mice. Fresh xenografts were passaged, implanted in triplicate in mice that were treated with 5-AZA daily for 28 days. These xenografts were then evaluated for genome-wide DNA methylation patterns using the Illumina Infinium HumanMethylation27 BeadChip array. Validation of the 32 candidate genes was performed by bisulfite sequencing (BS-seq) in a separate cohort of 6 ACC primary tumors and 6 normal control salivary gland tissues. Hypermethylation was identified in the HCN2 gene promoter in all 6 control tissues, but hypomethylation was found in all 6 ACC tumor tissues. Quantitative validation of HCN2 promoter methylation level in the region detected by BS-seq was performed in a larger cohort of primary tumors (n=32) confirming significant HCN2 hypomethylation in ACCs compared with normal samples (n=10; P=0.04). HCN2 immunohistochemical staining was performed on an ACC tissue microarray. HCN2 staining intensity and H-score, but not percentage of the positively stained cells, were significantly stronger in normal tissues than those of ACC tissues. With our novel screening and sequencing methods, we identified several gene candidates that were methylated. The most significant of these genes, HCN2, was actually hypomethylated in tumors. However, promoter methylation status does not appear to be a major determinant of HCN2 expression in normal and ACC tissues. HCN2 hypomethylation is a biomarker of ACC and may play an important role in the

    Background A20, also known as tumor necrosis factor α induced protein 3 (TNFaip3), is a cytoplasmic zinc finger protein that inhibits nuclear factor kappa-B (NF-κB) activity and prevents tumor necrosis factor (TNF)-mediated programmed cell death. NF-κB is a transcription factor that regulates expression of genes involved in cell proliferation,cell survival and anti-apoptosis. Several studies have implicated that the NF-κB signal pathway is associated with angiogenesis and clinico-pathological process of adenoid cystic carcinoma (ACC) of the salivary glands.Methods The ability of overexpression of A20 to influence the biological behavior and invasion of ACC cells was examined. The cells were stably transfected with full-length A20 cDNA. Stable gene transfer was verified by realtime-polymerase chain reaction (PCR) and Western blot analysis. The change of cell biological behavior was examined by methyl thiazolyl tetrazolium (MTT) and NF-κB luciferase reporter assay and the invasion of the cells was examined by a Matrigel invasion chamber.Results pEGPFN3-A20 gene was stably transferred into ACC-2 cells and overexpressed. When cells were treated with TNFα, the NF-κB activity of ACC-2-A20 cells could be down-regulated about 46.32% in contrast to ACC-2-GFP cells (P<0.05). A20 potently inhibited growth of A20 transfectant ACC-2-A20 compared with control vector transfected groups and the ACC-2 empty control group (P<0.05). The ACC-2-A20 cells showed significantly reduced ability to invade through Matrigei-coated filters compared to ACC-2-GFP and ACC-2 cells. The inhibition rate was up to 71.05% (P<0.05).Conclusions A20 gene transfer is associated with decreased tumor invasion, in part via the down-regulation of NF-κB expression, providing evidence for a potential application of A20 in designing a treatment modality for salivary gland cancers such as ACC.

  18. The effect of proteoglycans inhibited by RNA interference on metastatic characters of human salivary adenoid cystic carcinoma

    Salivary adenoid cystic carcinoma (SACC) is one of the most common malignancies of salivary gland. Recurrence or/and early metastasis is its biological properties. In SACC, neoplastic myoepithelial cells secrete proteoglycans unconventionally full of the cribriform or tubular and glandular structures of SACC. Literatures have demonstrated that extracellular matrix provided an essential microenvironment for the biological behavior of SACC. However, there is rare study of the effect of proteoglycans on the potential metastasis of SACC. In this study, human xylosyltransferase-I (XTLY-I) gene, which catalyzes the rate-limited step of proteoglycans biosynthesis, was knocked down by RNA interference (RNAi) to inhibit the proteoglycans biosynthesis in SACC cell line with high tendency of lung metastasis (SACC-M). The impact of down-regulated proteoglycans on the metastasis characters of SACC-M cells was analyzed and discussed. This research could provide a new idea for the clinical treatment of SACC. The eukaryotic expression vector of short hairpin RNA (shRNA) targeting XTLY-I gene was constructed and transfected into SACC-M cells. A stably transfectant cell line named SACC-M-WJ4 was isolated. The XTLY-I expression was measured by real-time PCR and Western blot; the reduction of proteoglycans was measured. The invasion and metastasis of SACC-M-WJ4 cells were detected; the effect of down-regulated proteoglycans on the potential lung metastasis of nude mice was observed, respectively. The shRNA plasmid targeting XTLY-I gene showed powerful efficiency of RNAi. The mRNA level of target gene decreased by 86.81%, the protein level was decreased by 80.10%, respectively. The silence of XTLY-I gene resulted in the reduction of proteoglycans significantly in SACC-M-WJ4 cells. The inhibitory rate of proteoglycans was 58.17% (24 h), 66.06% (48 h), 57.91% (72 h), 59.36% (96 h), and 55.65% (120 h), respectively. The reduction of proteoglycans suppressed the adhesion, invasion and

    2016-01-01

    The objective of the present retrospective study based on the analysis of 791 medical cards was to investigate microflora localized at the pharyngeal tonsil surface in the children living in the city of Chelyabinsk and presenting with exacerbation of chronic adenoiditis. 66% of the patients with this condition were 4-6 year old children. The most commonly documented were the associations composed of resident species S. alpha-haemoliticus and S. epidermidis together with pathobiontic S. aureus. S. beta-haemoliticus and S. pneumoniae occurred most frequently whereas H. influenza and some representatives of the genus Enterobacteriaceae were less numerous. Fungi of the genus Candida were identified in 25.4% of the samples at a titer above 10^4. In 23.7% of the cases, these fungi were found in the associations with S. aureus which resulted in mutual potentiation of the pathogenicity factor. PMID:26977565

    We report the case of a 63-year-old woman with adenoid cystic carcinoma of the lower trachea treated by resection of 11 of the 18 cartilaginous rings (61%) of the total length. The little remaining membranous portion of the carina was sewn up to create a margin for anastomosis. The anastomotic sites could be approximated by the mobilization of the cervical trachea and the left main bronchus, pulling across the traction sutures, and anteflexion of the neck. The patient's postoperative course was uneventful without any complications associated with anastomosis. Because both the proximal and distal margins showed microscopic tumors, radiation therapy was performed with 50 Gy 2 months after surgery. The patient has a good social life without recurrence 20 months after surgery. PMID:25261213

  3. In vitro angiogenesis and expression of nuclear factor κB and VEGF in high and low metastasis cell lines of salivary gland Adenoid Cystic Carcinoma

    Adenoid cystic carcinoma is a high malignant carcinoma characterized by intensive local invasion and high incidence of distant metastasis. Although many reports have demonstrated that angiogenesis has played an important role in tumor metastasis, the relationship between metastasis characters and angiogenesis ability in high and low metastasis cell lines of Adenoid cystic carcinoma has rarely been reported. The present study aimed to compare the angiogenesis ability of ACC-M (high metastasis) and ACC-2 (low metastasis) cell lines in vitro. Furthermore, the activity of nuclear factor κappa B and the expression of vascular endothelial growth factor (VEGF) in ACC-2 and ACC-M were also detected. Electrophoretic mobility shift assay was used to detect nuclear factor κappa B activity. Semi-quantitative RT-PCR was used to quantify the mRNA level of VEGF. Immuofluorescence double staining and semi-quantitative confocal laser scanning analysis was carried out to detect nuclear factor κappa B nuclear localization and staining intensity of VEGF. The angiogenesis ability of ACC-M and ACC-2 was compared by an in vitro three-dimensional angiogenic model assay. The vector transfection assay was performed to transfect the PCMV-IκBαM vector into ACCs cell lines expressing the phosphorylation defective IκBαM. Nuclear factor κappa B activity and the rate of nuclear factor κappa B nuclear localization in ACC-M was significantly higher than that in ACC-2. Moreover, ACC-M exhibited higher mRNA and protein levels of vascular endothelial growth factor than ACC-2. VEGF mRNA expression was effectively decreased by inhibition of nuclear factor κappa B activity. Furthermore, ACC-M could remarkably stimulate the migration and tube formation of endothelial cells and induce The umbilical vein endothelial cells sprouting into the gel matrix. These results implicated that ACCs cells with higher metastasis feature might present greater angiogenesis ability

    2007-01-01

    Adenoid cystic carcinoma is a frequently occurring malignant salivary gland neoplasm. We studied the induction of protease activity by the laminin-derived peptide, SIKVAV, in cells (CAC2) derived from this neoplasm. Laminin α1 and matrix metalloproteinases (MMPs) 2 and 9 were immunolocalized in adenoid cystic carcinoma cells in vivo and in vitro. CAC2 cells cultured on SIKVAV showed a dose-dependent increase of MMP9 as detected by zymography and colocalization of α3 and α6 integrins. Small interfering RNA (siRNA) knockdown of integrin expression in CAC2 cells resulted in decreased adhesion to the peptide. SIKVAV affinity chromatography and immunoblot analysis showed that α3, α6, and β1 integrins were eluted from the SIKVAV column, which was confirmed by mass spectrometry and a solid-phase binding assay. Small interfering RNA experiments also showed that these integrins, through extracellular signal-regulated kinase (ERK) 1/2 signaling, regulate MMP secretion induced by SIKVAV in CAC2 cells. We propose that SIKVAV increases protease activity of a human salivary gland adenoid cystic carcinoma cell line through α3β1 and α6β1 integrins and the ERK 1/2 signaling pathway. PMID:17591960

  8. The influence of positive margins and nerve invasion in adenoid cystic carcinoma of the head and neck treated with surgery and radiation

    Purpose: Surgery is the primary treatment for adenoid cystic carcinomas arising from major and minor salivary glands of the head and neck. However, local recurrence is frequent because of the infiltrative growth pattern and perineural spread associated with these tumors. At UTMDACC, we have had a long-standing policy of using postoperative radiotherapy to reduce the risk of local recurrence and to avoid the need for radical surgery; this 30-year retrospective study analyzes the results of this combined modality approach. Methods and Materials: Between 1962 and 1991, 198 patients ages 13-82 years, with adenoid cystic carcinomas of the head and neck, received postoperative radiotherapy for known or suspected microscopic residual disease following surgery. Distribution of primary sites was: parotid: 30 patients; submandibular/sublingual: 41 patients; lacrimal: 5 patients; and minor salivary glands: 122 patients. Eighty-three patients (42%) had microscopic positive margins and an additional 55 (28%) had close (≤5 mm) or uncertain margins. One hundred thirty-six patients (69%) had perineural spread with invasion of a major (named) nerve in 55 patients (28%). Using radiation techniques appropriate to the primary site, a median dose of 60 Gy (range 50-69 Gy) was delivered to the tumor bed. Follow-up ranged from 5-341 months (median, 93 months). All surviving patients had a minimum of 2 years follow-up. Results: Twenty-three patients (12%) had local recurrences with 5-, 10-, and 15-year actuarial local control rates of 95%, 86%, and 79%, respectively. Fifteen of the 83 patients (18%) with positive margins developed local recurrences, compared to 5 of 55 patients (9%) with close or uncertain margins, and 3 of 60 patients (5%) with negative margins (p 0.02). Patients with and without a major (named) nerve involved had crude failure rates of 18% (10 out of 55) and 9% (13 out of 143), respectively (p 0.02). There was a trend toward better local control with increasing dose

  9. Accuracy of methionine-PET in predicting the efficacy of heavy-particle therapy on primary adenoid cystic carcinomas of the head and neck

    We evaluated whether or not PET or PET/CT using L-methyl-[11C]-methionine (MET) can allow for the early prediction of local recurrence and metastasis, as well as the prognosis (disease-specific survival), in patients with adenoid cystic carcinoma of the head and neck treated by carbon ion beam radiotherapy. This was a retrospective cohort study of sixty-seven patients who underwent a MET-PET or PET/CT study prior to and one month after the completion of carbon ion radiotherapy (CIRT). The minimum follow-up period for survivors was 12 months. The MET accumulation of the tumor was evaluated using the semiquantitative tumor to normal tissue ratio (TNR). A univariate analysis was conducted using the log-rank method, and the Cox model was used in a multivariate survival regression analysis. The average TNR prior to and following treatment was 4.8 (±1.5) and 3.0 (±1.3), respectively, showing a significant decrease following treatment. In the univariate analysis, a high TNR prior to treatment (TNRpre) was a significant factor for predicting the occurrence of metastasis and the disease-specific survival. A high TNR following treatment (TNRpost) was a significant factor for predicting the development of local recurrence. The residual ratio of TNR changes (TNRratio) seemed to be less useful than the TNRpre. In the multivariate analysis, the TNRpost and tumor size were the factors found to significantly influence the risk of local recurrence. The TNRpre, TNRratio and tumor size were all significant factors influencing the occurrence of metastasis. Regarding the disease-specific survival, the TNRpre and age were the only factors with a significant influence on the outcome. The TNRpre was a factor that was significantly related to the occurrence of metastasis and the disease-specific survival after CIRT for adenoid cystic carcinoma of the head and neck. The TNRpost was a factor that was significantly related to the development of local recurrence. Thus, MET-PET or PET/CT can

    The authors aimed to evaluate the effects of obstructive sleep apnea in children as a result of adenoid and/or adenotonsillar hypertrophy on maternal psychologic status. The study sample comprised the mothers of 66 children aged 3 to 15 years (mean age: 7.55 ± 2.94 years) who were scheduled to undergo curette adenoidectomy or adenotonsillectomy because of airway obstruction. The mothers completed the 14-item Hospital Anxiety and Depression Scale (HADS), 20-item State-Trait Anxiety Inventory-1 (STAI-1), and 20-item State-Trait Anxiety Inventory-2 (STAI-2) questionnaires before the operation and 10 days afterwards. Mothers who were under psychiatric treatment or declined to fill the questionnaires were excluded from the study. The results obtained postoperatively by day 10, when all the children had considerable improvement in their breathing, were analyzed as control data. The mean postoperative HAD-A and HAD-D scores of the mothers were significantly lower than the mean preoperative scores (P < 0.001). Mothers' mean STAI-1 and STAI-2 scores were also significantly lower postoperatively (P < 0.001). Pediatric adenoidectomy or adenotonsillectomy to relieve airway obstruction has a beneficial effect not only on the health of pediatric patients but also on the psychologic status of their mothers.

    Objective: To explore the influence of extract of Ginkgo biloba (EGB) on the proliferation, apoptosis of ACC-2 cell and Survivin gene expression in adenoid cystic carcinoma (ACC) of lacrimal gland. Methods:ACC-2 cell in human with ACC of lacrimal gland was in vitro cultured. MTT method was used for cell proliferation detection. Annexin V/PI double-staining flow cytometer was used to detect cell apoptosis and cell cycle. Survivin gene expression was analyzed by RT-PCR and Western blotting. Results: EGB had inhibitory effect on the proliferation of ACC-2 cell with significant dose-effect relationship, and there was statistical difference when compared with the control group (P<0.01). The inhibitory concentration 50 % (IC50) is 88 mg/L. The flow cytometer test indicated that EGB can gradually increase ACC-2 cell in G0-G1 stage and decrease it in G2-M and S stage. With the increase of dose, the apoptosis rate of ACC-2 cell was obviously increased (P<0.05 or P<0.01). EGB had certain inhibitory effect on Survivin gene expression of ACC-2 cell, and Survivin gene expression was decreased with the increasing of the EGB concentration (P<0.01). Conclusions:EGB can effectively inhibit Survivin gene expression of ACC-2 cell in human with ACC of lacrimal gland, induce the apoptosis of ACC-2 cell and inhibit tumor cell proliferation.

    This study investigates whether Wnt components play a role in carcinogenesis, or the invasion and metastasis of salivary glands, also referred to as adenoid cystic carcinoma (sAdCC). Several sAdCC cell lines with low invasive potential (ACC-2), high metastatic potential (ACC-M), and higher invasive potential (T-ACC-M) were examined to determine whether Wnt components correlate with tumors' invasive and metastatic behavior. Immunohistochemistry was performed in a sAdCC tissue array. ACC-M expressed higher levels of Wnt-1, beta-catenin and lower WIF-1 compared to ACC-2 (PWIF-1 compared to ACC-2 and ACC-M. Immuno-histochemistry showed up-regulation of Wnt-1 and down-regulation of WIF-1 in sAdCC compared with normal salivary glands. Beta-catenin was found in the cytoplasm and nuclei of sAdCC. Dislocation of E-cadherin in sAdCC was observed. These results suggest that sAdCC exhibits diverse expressions of Wnt components. It has an important relationship with the invasive phenotype of these cells. PMID:26405993

    Adenoid cystic carcinoma (ACC) is an exocrine gland tumor accounting for approximately 10%-15% of all epithelial salivary neoplasms and occurs most often in the parotid and submandibular glands. Metastatic pituitary tumors are rare, and there is only 1 previously reported case of parotid ACC metastatic to the pituitary. Magnetic resonance elastography (MRE) is a dynamic magnetic resonance imaging (MRI)-based technique that measures the propagation of mechanically induced shear waves through a particular tissue to determine stiffness and offers a method to evaluate tissue consistency. We present the case of a 72-year-old woman with a remote history of parotid gland ACC and subsequent lung metastases presented after a fall that resulted in facial trauma. A non-contrast head computed tomography scan revealed a sellar/suprasellar mass, and follow-up MRI revealed a well-defined, enhancing 3.8-cm lesion. MRE showed the tumor to be firm. The tumor was resected through a transsphenoidal approach and was consistent with the MRE findings. Pathology returned as metastatic ACC. We report the second case of ACC metastatic to pituitary and the first firm pituitary tumor found by MRE and discuss the potential diagnostic value of MRE in pituitary lesions. PMID:27018011

    Beclin 1 plays a critical role in autophagy and functions as a haploinsufficient tumor suppressor. The expression and prognostic significance of beclin 1 in head and neck adenoid cystic carcinoma (ACC) are largely unexplored. Therefore, we investigated the expression of beclin 1, Bcl-2, and p53 in head and neck ACC tissue. Tissue samples from 35 cases (15 females, 20 males) of head and neck ACC were utilized for immunohistochemistry. Beclin 1 expression was observed in 32 cases (91.4%) and considered to be high in 15 cases (42.9%) and low in 20 cases (57.1%). Beclin 1 expression was significantly correlated with a histological growth pattern (P=0.046) and histological grade (P=0.037). Beclin 1 expression was inversely correlated with Bcl-2 expression (P=0.013) and significantly associated with overall survival (P=0.006). Bcl-2 and p53 expression were observed in 21 cases (60.0%) and 16 cases (45.7%). Bcl-2 expression was significantly correlated with perineural invasion (P=0.041) and not associated with overall survival (P=0.053). p53 expression was directly correlated with beclin 1 expression (P=0.044). Our results indicated that beclin 1 may be a novel, promising prognostic factor for clinical outcome in head and neck ACC patients and may play a part in the development of head and neck ACC by interacting with Bcl-2 and p53.

    Primary cutaneous adenoid cystic carcinoma (PCACC) is a rare adnexal skin tumor first described in 1975, of which merely 62 cases have so far been studied in detail and reported in the English literature. PCACC is usually regarded as apocrine in origin/differentiation, but its precise histogenesis is still not well known. PCACC has in most cases a rather indolent course but can produce local recurrences and, more rarely, regional (lymph node) and distant (pulmonary) metastases. We report herein a Greek woman with a long-standing PCACC that grew slowly over several years and produced metastasis in the regional lymph nodes, highlighting the potentially aggressive course of this tumor. The primary and metastatic tumors were studied immunohistochemically and proved to express several (sweat gland-related) antigens (such as keratin 7, epithelial membrane antigen, CD10, and CD117) but neither hormonal receptors nor p63 or Gross Cystic disease Fluid Protein 15. The salient clinicopathologic features of this rare cutaneous adnexal tumor are reviewed. PMID:23812021

  17. Treatment outcomes of particle radiotherapy using protons or carbon ions as a single-modality therapy for adenoid cystic carcinoma of the head and neck

    Background and purpose: The aim of this study was to retrospectively analyse the outcomes of cases of adenoid cystic carcinomas (ACCs) of the head and neck that were treated at a single institution with particle therapy consisting of either protons or carbon ions. Methods and materials: Between February 2002 and March 2012, 80 patients were treated with proton therapy (PT) or carbon ion therapy (CIT) alone. PT and CIT were employed in 40 (50%) patients each, and more than half of the patients received 65.0 GyE in 26 fractions (n = 47, 59%). Results: The median duration of follow-up was 38 months (range, 6–115 months). For all patients, the 5-year for overall survival (OS) rate, progression-free survival (PFS) rate, and local control (LC) rate were 63%, 39%, and 75%, respectively. No significant differences between PT and CIT were observed. The 5-year LC rates for T4 and inoperable cases were 66% and 68%, respectively. Twenty-one patients (26%) experienced grade 3 or greater late toxicities, including three patients who developed grade 5 bleeding from nasopharyngeal ulcers. Conclusions: Particle radiotherapy for ACC achieves favourable LC, and its efficacy in inoperable or T4 cases is promising. There were no significant differences between PT and CIT in terms of OS, PFS and LC

  18. c-Kit Expression is Rate-Limiting for Stem Cell Factor-Mediated Disease Progression in Adenoid Cystic Carcinoma of the Salivary Glands

    2014-10-01

    Full Text Available Adenoid cystic carcinoma (ACC is an aggressive malignant neoplasm of the salivary glands in which c-Kit is overexpressed and activated, although the mechanism for this is as yet unclear. We analyzed 27 sporadic ACC tumor specimens to examine the biologic and clinical significance of c-Kit activation. Mutational analysis revealed expression of wild-type c-Kit in all, eliminating gene mutation as a cause of activation. Because stem cell factor (SCF is c-Kit's sole ligand, we analyzed its expression in the tumor cells and their environment. Immunohistochemistry revealed its presence in c-Kit–positive tumor cells, suggesting an activation of autocrine signaling. We observed a significant induction of ERK1/2 in the cells. SCF staining was also found in other types of non-cancerous cells adjacent to tumors within salivary glands, including stromal fibroblasts, neutrophils, peripheral nerve, skeletal muscle, vascular endothelial cells, mucous acinar cells, and intercalated ducts. Quantitative PCR showed that the top quartile of c-Kit mRNA expression distinguished ACCs from normal salivary tissues and was cross-correlated with short-term poor prognosis. Expression levels of SCF and c-Kit were highly correlated in the cases with perineural invasion. These observations suggest that c-Kit is potentially activated by receptor dimerization upon stimulation by SCF in ACC, and that the highest quartile of c-Kit mRNA expression could be a predictor of poor prognosis. Our findings may support an avenue for c-Kit-targeted therapy to improve disease control in ACC patients harboring the top quartile of c-Kit mRNA expression.

  19. Adding concurrent chemotherapy to postoperative radiotherapy improves locoregional control but Not overall survival in patients with salivary gland adenoid cystic carcinoma—a propensity score matched study

    To compare the long-term outcomes in patients with salivary gland adenoid cystic carcinoma (SGACC) treated with post-operative chemoradiotherapy (POCRT) versus post-operative radiotherapy (PORT). We retrospectively reviewed the records of 91 SGACC patients treated with surgery followed by PORT (n = 58) or POCRT (n = 33) between 2000 and 2013. Treatment outcomes between groups were compared using propensity score matching (1:1 nearest neighbor). The median radiation dose was 66 Gy, and patients were followed up for a median of 71 months. Cisplatin-based concurrent regimens were the most commonly used chemotherapy schedules. In the entire study cohort, patients undergoing POCRT showed a trend toward higher locoregional control (LRC) rates than those treated with PORT alone at both 5 and 8 years (97 and 97 % versus 84 and 79 %, respectively; P = .066). Distant metastases were the most common form of treatment failure and occurred in 31 (34 %) patients (PORT, n = 17; POCRT, n = 14). After propensity score matching (33 pairs), patients receiving POCRT had 5- and 8 year LRC rates of 97 and 97 %, respectively, compared with 79 and 67 % for patients treated with PORT alone (P = .017). The two groups did not differ significantly in terms of distant metastasis-free survival (DMFS), disease-free survival (DFS), and overall survival (OS). However, a significantly better opioid-requiring pain-free survival (ORPFS) was achieved in POCRT group (P = .038). Subgroup analyses revealed that patients with stage III − IV disease (P = .040 and .017), positive surgical margins (P = .011 and .050), or perineural invasion (P = .013 and .035) had significantly higher 5- and 8 year LRC and ORPFS when treated with POCRT, respectively. In SGACC patients, adding concurrent chemotherapy to PORT may increase LRC and ORPFS rates, particularly in presence of stage III − IV disease, positive surgical margins, or perineural invasion. However, no significant differences in DMFS, DFS, and OS were

    Adenoid cystic carcinoma (ACC) is an aggressive malignant neoplasm of the secretory glands. Conventional chemotherapy has poor effectiveness against metastatic ACC. Thus, a novel effective therapy is needed against metastatic ACC. A majority of ACCs (up to 94%) express c-kit. Imatinib is monoclonal antibody with specific activity against c-kit but has not been found to be effective in treating patients with ACC in which c-kit is overexpressed and activated. The NF-κB and mTOR pathways have been shown that ubiquitously and concurrently activated, indicating that the inhibition of these pathways may represent a novel treatment approach for patients with ACC. Curcumin has been shown to inhibit NF-κB and NF-κB-related pathways. 43-year-old patient was diagnosed ACC from submandibular salivary gland. After complete resection of tumor adjuvant radiotherapy was initiated. Seven years later multiple lung metastases were detected and ACC was confirmed by re-biopsy. First-line chemotherapy failed. NF-κB and c-kit were overexpressed in the metastatic specimens. Therefore, we treated the patient with metastatic chemoresistant ACC with imatinib 400mg/day and intravenous curcumin 225mg/m(2) twice a week plus oral bioavailable curcumin Arantal(®) 2×84mg/day. At 24 months, we observed near complete anatomic and complete metabolic response. To our knowledge, this is the first report of a patient with a c-kit-positive ACC that is successfully treated with the combination of imatinib and curcumin in an integrative approach. PMID:27515884

    Adenoid cystic carcinoma (AdCC) of the breast is an uncommon but distinct neoplasm composed of a dual cell population polarized around true glandular (luminal) spaces and pseudolumina. The aim of this study was to clarify whether various immunohistochemical markers (CK7, EMA, CD117, p63, calponin, CD10, S100, CK5/6, CK14, vimentin, and type IV collagen) can distinguish between the two cell types in classical AdCC (n = 14) and in collagenous spherulosis (n = 5). The sensitivity and specificity of these 11 markers to distinguish luminal from abluminal cells were evaluated using a curve created by plotting the true-positive rate (sensitivity) against the false-positive rate (1 - specificity) at threshold settings of 0, 10, 50, and 70 %. The most sensitive and specific markers for luminal cells in AdCC were CK7 and EMA; those for abluminal cells were type IV collagen, p63, and vimentin. CD10 and S100 did not act as abluminal markers in AdCC. CK5/6, one of the basal/myoepithelial markers, was expressed more frequently in luminal than in abluminal cells of AdCC. Thus, CK5/6 immunostaining resulted in a reverse expression pattern, analogous to what we recently documented in clear cells in mammary adenomyoepithelioma. In conclusion, compared with myoepithelial/abluminal cells of normal breast or collagenous spherulosis, the neoplastic abluminal cells of classical AdCC are characterized by enhanced vimentin and attenuated CD10 and S100. Furthermore, the luminal cells of AdCC show a unique aberrant staining pattern for CK5/6 that may aid in the differential diagnosis. PMID:27240462

    Purpose To investigate the clinicopathologic features of cervical adenoid basal cell carcinoma. Methods Clinical and pathological data were analyzed in 12 cases of cervical adenoid basal cell carcinoma and the relevant literatures were reviewed. Results The age of 12 cases of with cervical adenoid basal cell cancer patients ranged from 36~70 years ( mean:53. 3 years) , with a medi-an age of 51. 5 years. Amongst 12 patients who contained no gross definite lesion, 5 patients (41. 7%) had the symptoms of vaginal bleeding. 8 cases of patients underwent hysterectomy, while the other four received cervical conization. Cervical intraepithelial neopla-sia ( CIN) lesions were observed in all 12 cases. The tumor cells were small and uniform, with dark oval nuclei without conspicuous nucleoli and scanty cytoplasm. Tumor infiltrated into the stroma in nests and cords. Glandular differentiation within tumor nests were seen in 12 cases, including two cases of squamous cell differentiation accompanied by partial and minor interstitial edema. Peripheral palisading cells around tumor nests were also found. The infiltrating depth of tumor ranged from 0. 5~10 mm with the average 4. 12 mm. Cancer embolis were available in 2 cases with no lymph node metastasis. 10 cases followed up for 3~78 months with no recur-rence and metastasis, but 2 cases were lost. Conclusion Adenoid basal cell carcinoma is a rare uterine cervical tumor found in post-menopausal women, which are often accompanied with CIN. This tumor has a favorable prognosis and should be clearly separated from adenoid cystic carcinoma and other tumors which also have infiltrative growth pattern.%目的:探讨子宫颈腺样基底细胞癌的临床病理学特征。方法回顾性分析12例子宫颈腺样基底细胞癌患者的临床病理资料、组织学特征及免疫表型,并复习相关文献。结果12例子宫颈腺样基底细胞癌患者年龄36~70岁,平均53.3岁。5例(41.7%)有阴道出血症状,12例中8

  3. The T-box transcription factor Brachyury regulates epithelial–mesenchymal transition in association with cancer stem-like cells in adenoid cystic carcinoma cells

    The high frequencies of recurrence and distant metastasis of adenoid cystic carcinoma (AdCC) emphasize the need to better understand the biological factors associated with these outcomes. To analyze the mechanisms of AdCC metastasis, we established the green fluorescence protein (GFP)-transfected subline ACCS-GFP from the AdCC parental cell line and the metastatic ACCS-M GFP line from an in vivo metastasis model. Using these cell lines, we investigated the involvement of the epithelial–mesenchymal transition (EMT) and cancer stem cell (CSCs) in AdCC metastasis by real-time RT-PCR for EMT related genes and stem cell markers. Characteristics of CSCs were also analyzed by sphere-forming ability and tumorigenicity. Short hairpin RNA (shRNA) silencing of target gene was also performed. ACCS-M GFP demonstrated characteristics of EMT and additionally displayed sphere-forming ability and high expression of EMT-related genes (Snail, Twist1, Twist2, Slug, zinc finger E-box binding homeobox 1 and 2 [Zeb1 and Zeb2], glycogen synthase kinase 3 beta [Gsk3β and transforming growth factor beta 2 [Tgf-β2]), stem cell markers (Nodal, Lefty, Oct-4, Pax6, Rex1, and Nanog), and differentiation markers (sex determining region Y [Sox2], Brachyury, and alpha fetoprotein [Afp]). These observations suggest that ACCS-M GFP shows the characteristics of CSCs and CSCs may be involved in the EMT of AdCC. Surprisingly, shRNA silencing of the T-box transcription factor Brachyury (also a differentiation marker) resulted in downregulation of the EMT and stem cell markers. In addition, sphere-forming ability, EMT characteristics, and tumorigenicity were simultaneously lost. Brachyury expression in clinical samples of AdCC was extremely high and closely related to EMT. This finding suggests that regulation of EMT by Brachyury in clinical AdCC may parallel that observed in vitro in this study. The use of a single cell line is a limitation of this study. However, parallel data from in vitro and

    tumor that contains a mixture of malignant cells with squamous and glandular differentiation. The literature points to the importance of making this diagnosis when the cellular components are still well differentiated in the sample, otherwise the tumor may be erroneously interpreted as squamous carcinoma or adenocarcinoma. This study describes an unusual presentation of a adenosquamous carcinoma in a 47 year old patient. After conflicting cytological diagnoses and a history of abnormal uterine bleeding caused by cervical endometriosis, the patient was subjected to radical hysterectomy and a final diagnosis was obtained. The tumor was diagnosed as adenosquamous carcinoma. In many aspects, however, it was similar to the adenoid basal carcinoma. Characteristic features of the adenoid basal carcinoma such as the presence of high-grade squamous intraepithelial lesion in the surface epithelium, squamous and glandular differentiation in the center of the neoplastic mass, and basaloid cells in deep areas of the tumor were observed. Therefore, the following elements usually absent from adenoid basal carcinoma were present in this case: atypia and mitotic figures in undifferentiated cells, squamous-mucinous intraepithelial lesion (SMILE in the superficial areas. Epidemiological and clinical data, such as patient age (47, race (white and presentation (a cervical mass, concurred to exclude the diagnosis of adenoid basal carcinoma. Other differential diagnoses include pure squamous carcinoma or adenocarcinoma, collision tumor, and endometrial adenocarcinoma with squamous differentiation invading the uterine cervix.

    ObjectiveTo study the correlation of children epstein-barr virus(EBV)infection and tonsils and adenoid hyper-trophy in children.MethodsSeventy children with tonsil and adenoid hypertrophy from the June 2013 to June 2014 in our hospital were included in this research. According to the children age,sex, weight,etc,they were divided into different groups. And EBV infection was evaluated and compared.ResultsIn 70 cases of children with adenoid hypertrophy were tonsils,a total of 47 cases with EBV infection. Among the EBV-DNA positive cases,the male children accounted for 66.67%(30/45),while female patients accounted for 68.00%(17/25). There was no significant difference (P 0.05). The EBV infection rate in children with a duration of disease less than 30 months was 62.50%(30/48), 78.57%(11/14) with duration of 30 to 60 months,75%(6/8)with duration>60 months . EBV infection rates among the three groups had no significant difference(P>0.05). EBV infection rate in children of body weight of 0~20 kg was 70.59%(12/17),69.05%(29.42) of 20~40 kg,54.55%(6/11)of 40~60 kg. Children with different weight had no significant difference in EBV infection(P>0.05). EBV infection in children with snoring accounted for 68.63%(35/51), 63.16%(12/51)in children without snoring. There was no significant difference(P>0.05)between the two groups.ConclusionEBV infection among children has relevance to tonsil and adenoid hypertrophy. EBV in tonsil and adenoid tissues showed no significant correlation with the patient's age,sex,weight,duration of disease.%目的研究儿童EB病毒(epstein-barr virus,EBV)感染与扁桃体腺样体肥大的相关性。方法选取2013年6月~2014年6月期间我院收治的70例扁桃体腺样体肥大患儿,根据年龄、性别、体重等分为不同组别,比较不同组别之间的EBV感染情况。结果在70例扁桃体腺样体肥大患儿中,有47例伴EBV感染。其中男性66.67%(30/45),女性68.00%(17/25),两

    Objective To investigate clinical application value of low-dose 64-slice spiral CT scanning technology in the ade-noidal hypertrophy of children. Methods 100 cases of children with adenoidal hypertrophy underwent low-dose(group A)and con-ventional-dose (group B)64-slice spiral CT scanning. The A/N ratio,Dand radiation dose in two groups were compared. Results The A/N ratio (P=0.981) and D (P=0.199) showed no significant difference between low-dose CT scanning and conventional-dose CT scanning (P=0.981). The CTDIvol of low-dose CT scanning was 6.93mGy and the CTDIvol of conventional-doses was 27. 92mGy. The CTDIvol of low-dose CT scanning decreased about 75%as compared with those of conventional dose scanning. Con-clusion The diagnostic result of image of low dose CT scanning is the same as that of conventional dose scanning,and the low-dose spiral CT scanning in children with adenoidal hypertrophy can substitute the conventional-dose spiral CT scanning.%目的:探讨低剂量64层螺旋CT扫描技术在儿童腺样体肥大中的应用。方法对100例临床疑似腺样体肥大儿童行64层螺旋CT低剂量和常规剂量扫描,将其随机分为两组,对比两种剂量扫描的鼻咽气腔前后径A/N比值和鼻咽气腔有效气道的前后径(D值)及患者的辐射剂量。结果64层螺旋CT低剂量扫描与常规剂量扫描之间鼻咽气腔前后径A/N比值无统计学差异(P=0.981);低剂量组与常规剂量组鼻咽气腔有效气道的前后径(D值)无统计学差异(P=0.199)。低剂量CT扫描显示儿童鼻咽部容积CT剂量指数CTDIvol为6.93mGy,常规剂量CTDIvol为27.92mGy。低剂量与常规剂量相比,其CTDIvol降低了约75%的辐射剂量。结论64层螺旋CT低剂量扫描对腺样体肥大的诊断结果与常规剂量均相同,故64层螺旋CT低剂量扫描临床疑似腺样体肥大的患者,完全能替代常规剂量的64层螺旋CT扫描。

    We present the main MR features of cystic lesions around the knee joint. Popliteal cysts are the most frequently seen. The usually result from extrusion of joint fluid into the gastrocnemio-semimembranosus bursa but they can have an atypical location or extension. They are most often due to a meniscal, ligamentous, degenerative or inflammatory joint disease responsible for a chronic joint effusion. Meniscal cysts are always associated with a horizontal tear. Medial meniscal cysts are larger and can extend far from the joint. Bursitis occur as a result of inflammation or infection of a bursa. Their location is stereotyped and they do not communicate with the knee joint. Ganglion cysts or ganglia are benign cystic lesions which can affect peri-articular tissues as well as subchondral bone or cruciate ligaments. MRI is now a simple and noninvasive way of obtaining etiologic diagnosis and guiding therapy. (authors). 46 refs.

    Penile tumors are the rarest male urogenital tract tumors (1%). Squamous cell carcinoma is the most common histologic type (95%). Radical surgical excision, though often mutilating, remains the best treatment for localized stages, in terms of local control (6% local recurrence). There are other therapeutic weapons and their possible indications should be adapted to the locoregional extension and at a distance from the primary tumor. We report the case of Mr AS aged 61, without particular pathological antecedents, who consulted, 6 years before, for an ulcerated burgeoning in the anterior surface of the penile bleeding on contact, which extended along the penis, without involving the glans penis. Evolution was marked by tumor progression with extension to the anterior pelvic wall. The patient went into a critical state of hemorrhagic shock. After stabilizing the hemodynamic status, a biopsy of the penis lesion confirmed the diagnosis of well-differentiated squamous cell carcinoma. An evaluation of the extent of loco-regional recurrence and distant metastasis showed pulmonary micronodules in the right lung. The case was discussed at the Multidisciplinary Consultative Meeting and patient was deemed inoperable and offered palliative chemotherapy. The prognosis of advanced stages of penis cancer is reserved; their frequency in our context is related to the modesty of patients, which explains the causes of delay in medical examination. Only socio-cultural awareness allows early diagnosis and, therefore, a better prognosis. PMID:27231503

    PURPOSE:To investigate the expression of ErbB3 binding protein ebpl, E-cadherin, ICAM-1 and matrix metalloproteinase-9 (MMP-9) in salivary adenoid cystic carcinoma (SACC), and to explore their relationship with clinical pathological features. METHODS:Two-step immunohistochemical staining method was used to detect the expression of ebpl E-cadherin, ICAM-1 and MMP-9 in 33 cases with human SACC and 33 with para-cancerous normal tissues. All data were analyzed with SPSS17.0 software package. RESULTS:Positive expression rate of ebpl in SACC was 84.85%, lower than in normal salivary tissues (96.97%). Ebpl expression was significantly correlated to pathological pattern and clinical stage (P<0.05),but not correlated to gender and age. Positive expression rate of ebpl at Ⅰ- Ⅱ stage was higher than that of SACC at Ⅲ - Ⅳ stage; in regard to pathological typing, higher expression was found in adenoid tubular type than in solid type; the positive expression rate in patients with tumor metastasis was lower than in patients without metastasis (P<0.05). Expression of ebpl had a positive relationship with E-cadherin (r=0.851 ,P<0.01), while a negative relationship was found with MMP-9 (r=-0.364,P<0.05). CONCLUSIONS:Expression of ebpl may be associated with progression of SACC. Ebpl has important role in the generation and evolution of adenoid cystic carcinoma, and can be used as a useful indicator for clinical assessment of tumor biological behavior and prognosis in patients with adenoid cystic carcinoma.

Methods 17 cases of ACC and 26 cases of BCA were observed respectively with their clinical findings, histopathology and immunohistochemical staining for CK7、 Calponin、CDl 17 and Ki-67. Results Parotid gland was predilection site of BCA, whereas others salivary glands except parotid gland were predilection sites of ACC. The immunophenotype had some differences in two groups: immunohistochemical expression of CD117 in groups of ACC and BCA had statistical significance ( P < 0. 05 ), expression of Ki-67 in groups of BCA and ACC had statistical significance ( P <0. 01 ). Conclusions The diagnosis and differential diagnosis of ACC and BCA were based on their growth patterns and morphological characteristics. The immunohistochemical staining of CD117 and Ki-67 may contribute to differentical diagnosis.%目的 观察CK7、Calponin、CD117、Ki-67在涎腺腺样囊性癌(adenoid cystic carcinoma,ACC)和基底细胞腺瘤(basal cell adenoma,BCA)中的免疫表型及其病理组织形态学差异,以提高对该类肿瘤鉴别诊断的认识.方法 对发生于涎腺的26例BCA和17例ACC进行临床和病理组织形态观察并免疫组化标记(CK7、Calponin、CD117、Ki-67).结果 临床特点为两种肿瘤的发病年龄相似,但发生部位不同,ACC好发于腮腺以外的小涎腺,BCA多数发生于腮腺;病理特点为前者表现为浸润性生长并累及周围组织;免疫组化显示两种肿瘤存在免疫表型差异:其中CD117在ACC和BCA之间的强阳性率差异有统计学意义(P<0.05);Ki-67在BCA和ACC之间的强阳性率差异有统计学意义(P<0.01).结论 ACC具有浸润性生长的生物学特征,病理特点上与BCA鉴别主要基于两者的生长方式和组织形态学检查,CD117和Ki-67免疫组化标记有助于其鉴别诊断.

  17. Skeleton scintigraphy and radiologic data at 403 patients with prostata carcinom

    In a retrospective study 403 patients with prostatic carcinoma (PC) were examined to shed light on the relation between the rate of metastases and the stage of local tumor spread as well as the histomorphologic tumor type; to establish the rate of metastases detected by bone scanning versus radiology; and to compare the contributions of bone scanning versus radiology in monitoring the response of bone metastases to treatment. Results: (1) The rate of metastases was found to increase as a function of primary tumor size and increasing dedifferentiation; however, bone metastases were also seen in highly differentiated stage O and A PC. (2) Solitary metastases were confined to the pelvic bones and lumbar vertebrae. (3) About one third of all bone metastases were radiologically silent; in sporadic cases receiving contrasexual therapy they remained silent for more than 5 years. (4) Bone scnaning showed 73.3% of patients to respond to contrasexual therapy and 26.7% to be non- responders. (6) There were some differences or even discrepancies between bone scans and radiology in documenting the results of treatment. Conclusions: Repeated bone scans are required for monitoring the course of the disease even if the primary tumor is extremely small and histologically well differentiated. Bone scans are superior to radiology in detecting metastases. While repeat X-rays during the course of a disease furnish important information, they are unsuited for monitoring the response to treatment. (Author)

    Conformal radiotherapy is a promising therapeutic strategy for hepatocellular carcinoma (HCC), producing local control rates above 90% within the radiation beam. However, survival after radiotherapy remains limited by the high frequency of intra- and extra-hepatic recurrences, which occurs in 40-50 and 20-30% of cases, respectively. Sorafenib (BAY43-9006, Nexavar; Bayer, West Haven, CT) is a small molecule inhibitor that demonstrated potent activity to target v-raf murine sarcoma oncogene homologue B1 (BRAF) and VEGFR tyrosine kinases. Sorafenib is the only drug that demonstrated effectiveness to increase overall survival in advanced or metastatic hepatocellular carcinoma. The rationale to combine radiotherapy with sorafenib is the following: (1) targeting RAS-RAF-MAPK and VEGFR signaling pathways, which are specifically activated after exposure to radiation, and responsible for radio-resistance phenomenon; (2) enhancing the oxygen effect through normalization of the surviving tumor vasculature; and (3) synchronization of the cell cycle. Sorafenib and radiotherapy represent complementary strategies, as radiotherapy may be useful to prolong the effect of sorafenib through control of the macroscopic disease, when sorafenib may target latent microscopic disease. Sorafenib and radiotherapy associations are thus based on a relevant biological and clinical rationale and are being evaluated in ongoing phase I-II trials. (authors)

  19. Small bowel obstruction caused by peritoneal immunoglobulin G4-related disease mimicking carcinomators: Case report

    We hereby report a case of diffuse pelvic peritoneal involvement by immunoglobulin G4-related disease (IgG4-RD). Numerous pelvic masses and nodules showing delayed enhancement on enhanced abdominal CT were found to congregate in the pelvic organs of a 57-year-old female presenting with intestinal subocclusion. The differentiation between peritoneal IgG4-RD and pelvic peritoneal carcinomatosis was only made by histopathology and immunohistochemistry performed after surgical resection. Autoimmune pancreatitis represents the historical prototype of IgG4-RD, but the spectrum of manifestations involving various organs has expanded during the last decade. In this report, we shortly review this clinical entity.

    The absolute iodine intake, slowly ameliorated, in a population influences the epidemiology of thyroid carcinoma (TC) and of hyperthyroidism (HT). We have retrospectively evaluated the frequencies of associated TC and HT in a pre-Alpine region over a period amounting up to more than 30 years. The iodide salt (5 - 10 - 20 mg KI/kg since 1922 - 1962 - 1980) have progressively corrected the severe iodine deficit, prevailing at the beginning of century. The patients treated for TC by surgery and/or {sup *}I in our hospital have been grouped in 3 periods: A (before 1971), B (1971 - 1983) and C (1984 - 1996), according to the diagnosis of malignity. Recorded were the number/type of associated TC (histology/or cytology) and HT (blood/clinic/scintigraphy by {sup *}I dosages). (GB = disease of Graves-Basedow, UFA/MFA = HT by uni- or multifocal functional autonomy, FC = follicular C, PC = papillary C, AC anaplas.C). On 925 TC, the FC has fallen from 64% down to 32%, the TC increased from 25% up to 60%, while the AC and other different C were of stable frequencies. The low frequency of AC has remained stable and it was not associated to HT. The associated HT (n = 97) were UFA in 60% to 13%, MFA (around {+-} 30%) and GB in 10% to 40% of cases. In conclusion, at 70 years since its introduction, the effect of iodide salt remains beneficent. Actually, the epidemiologic evolution described in 1963 by Walthard maintains. Due to the continues slope down of FC and up of PC in Berne during the period 1945 -1996 the general prognostication of TC continues to improve 16 years after the last augmentation of iodine in salt in Switzerland. The general decrease of UFA following the major correction of iodine deficit explains its less frequent association with the TC

    Most of patients with hepatocellular carcinoma (HCC) cannot benefit from surgical therapies. Among non-surgical options, only radiofrequency can challenge surgery for small size tumours. Conformal radiotherapy is likely highly efficient on solitary tumours, but controlled studies are warranted to conclude. Other options are purely palliative. Trans-arterial hepatic chemo-embolization is the goal-standard for multifocal hepatocellular carcinoma and Sorafenib for hepatocellular carcinoma with portal vein invasion, leading to modest but significant benefit on survival rates. Yttrium-90 radio-embolization is under evaluation through controlled studies, and could be of major interest for multifocal hepatocellular carcinoma with or without portal venous invasion. (authors)

    We report here the clinical history of Mrs A. (37 years old). On November 1995 Mrs A. presents stereotypical paroxysmal (2 to 3 / month) strokes of type of sensation of fast palpitations followed by very intense cephalies and sweats. The hypothesis of a pheochromocytoma has been retained, confirmed by a very important increase in the urinary metanephrines and normetanephrines and of noradrenaline. The abdominal scanner evidenced a left supra-renal tumoral lesion and also a voluminous right-renal cyst overflowing the right supra-renal. In May 1996 Mrs A. benefited by a left supra-renal-ectomy which confirmed histologically a benign pheochromocytoma. Long after the intervention the patient is totally asymptomatic but the metanephrines remains high (3000 {mu} g/24 h). The scanner applied in December 1996 finds only the voluminous right-renal cyst formation which perturbs the supra-renal exploration and rises questions about relic thymus. A scintigraphy by MIBG-{sup 131}I evidenced on the images after 24 h a hyper-fixation with hepatic projections seeming to circumscribe a voluminous right-supra-renal lacuna, confirmed by injection of 20 mCi of pertechnetate, while at 48 h this image reinforces. The diagnosis of a cystized left pheochromocytoma was established while the thymus region was normal. A scintigraphy with somatostatin labelled by indium 111 finds the anomalies superimposed on those obtained by MIBG. The patient was operated in May 1997 and a diagnosis was histologically confirmed. In conclusion, the scintigraphy by MIBG {sup 131}I must be part in the examination for suspicion of pheochromocytoma and must be interpreted together with the TDM morphological data

    [ES] El carcinoma adenoideo quístico (CAQ) es un tumor epitelial maligno de glándulas salivales, que por lo general da metástasis tardíamente, pero es persistente y muy agresivo debido a su gran capacidad de infiltrar tejido adyacente y fibras nerviosas. El CAQ de senos paranasales puede diseminarse siguiendo el trayecto de los nervios craneales; su relación cercana con estructuras vitales, impide la resección completa del tumor quedando márgenes positivos hasta en un 80% de los pacientes, pr...

    Recent technological advances allow precise and safe radiation delivery in hepatocellular carcinoma. Stereotactic body radiotherapy is a conformal external beam radiation technique that uses a small number of relatively large fractions to deliver potent doses of radiation therapy to extracranial sites. It requires stringent breathing motion control and image guidance. Selective internal radiotherapy or radio-embolization refers to the injection of radioisotopes, usually delivered to liver tumors via the hepatic artery. Clinical results for both treatments show that excellent local control is possible with acceptable toxicity. Most appropriate patient populations and when which type of radiation therapy should be best employed in the vast therapeutic armamentarium of hepatocellular carcinoma are still to be clarified.

    In spite of local treatment the local defeat is a problem in O.R.L. cancerology. It has been demonstrated that some recurrences or second cancers in beforehand irradiated area could be sterilized by a new irradiation of high dose after perfect definition of the volume to treat and the certainty that recurrence will be localized.Numerous works have allowed to underline that a part of patients, with an O.R.L. recurrence can be treated again with curative aim with survival rate about 20 to 20 % at three years. The objective of this study was to test with a phase two study, the validation of a stereotaxic type reirradiation by Cyberknife associated to Cetuximab. (N.C.)

    Six cases of supra-scapular nerve entrapment by a ganglion cyst within the spino-glenoid notch or developed from the glenoid labrum are reported. Causes of injury or entrapment of the supra-scapular nerve are described including traction or kinking of the nerve, trauma, repetitive exercise, or compression by ganglion cyst. The patients had non specific pain, weakness, and atrophy of the spinatus musculature. Electromyography showed evidence of denervation atrophy. Patients had plain radiographs, arthrography, CT-arthrography, magnetic resonance imaging (MRI) and MR-arthrography. Masses that caused supra-scapular nerve entrapment were well localized and characterized with magnetic resonance imaging, reflecting the superior soft-tissue contrast of this modality. In addition, MRI may demonstrate atrophy of the spinatus muscles. MR-arthrography allows to visualize lesions of the glenoid labrum and in some cases, demonstrates cysts filling. (authors). 35 refs.

    Pancreatitis and sinusitis as presentations of Burkitt lymphoma are uncommon and rarely described in children. We describe here the case of a child who presented with symptoms suggestive of sinusitis unresponsive to antibiotics, with subsequent development of abdominal symptoms due to pancreatitis. He was eventually diagnosed with Burkitt lymphoma.

  11. Results of fast neutron therapy of adenoid cystic carcinoma of the salivary glands

    72 consecutive patients with ACC were treated with fast neutrons, 66 after surgery, 6 for primarily unresectable disease, 43/66 for macroscopic residual disease, 23/66 for unresectable recurrent disease. 45/72 tumors were localized in the minor, 27 in the major salivary glands. T-stage was in 13 pts T2, in 33 T3, in 26 T4; positive nodes were in 10 pts. M+ in 15 pts. Mean tumor volume was 89 cm3. Neutron therapy was 15.03 Gy in 3 weeks with 1.67 Gy per fraction three times per week. Individual computer assisted treatment planning was performed based on CT and/or MRI, using bolus material if necessary. Target volume was the macroscopic tumor volume with a generous safety margin. Results: Complete response was achieved in 28 pts, partial response in 35 pts. Local control was observed in 73.4% after a mean observation period of 36 months. Overall and recurrence free survival was 85%/81% at two years, and 58%/53% at 5 years (Kaplan-Meier). In univariate analysis tumor volume (> 100 cm3), distant metastases, histologic subtype (solid) and neutron dose (<15 Gy) turned out to be significant parameters for predicting outcome, in multivariate analysis tumor volume and histologic subtype remained the only significant parameters. Acute morbidity was grade III/IV (EORTC/RTOG) in 6% for skin (desquamation), in 4% for mucosa (ulceration), late morbidity (grade III/IV) in one patient with local temporal brain necrosis. (orig.)

    Hepatocellular carcinoma is a poor prognosis tumour. The potential curative therapeutic options are ortho-topic liver transplantation, surgical resection and radiofrequency ablation. Unfortunately, only a minority of patients (around 20%) are eligible for these techniques. Thus, patients can benefit from palliative options, such as trans-arterial chemo-embolization (TACE) or sorafenib that bring only modest benefit on survival. Conformal radiotherapy allows delivering high dose radiation within a precise tumour volume while sparing the surrounding liver parenchyma. As employed in mono-therapy, conformal radiotherapy is highly efficient for small size hepatocellular carcinoma (< 5 cm). Above 5 cm, its efficacy is more limited but its association with TACE gives spectacular rates of complete responses. Controlled phase 2 or 3 trials are urgently warranted to define its indications in the therapeutic algorithm of hepatocellular carcinoma. (authors)

    The Berlin-Buch and Heidelberg centres used fast neutron therapy in bronchial carcinomas. The neutron source was a cyclotron in Berlin-Buch/Rossendorf and a d-t generator in Heidelberg. Three hundred twelve patients with inoperable bronchial carcinoma were treated with fast neutron therapy alone or in combination with photons. The results were then compared with those obtained from 594 patients treated only with photons. Altogether, 788 were treated in Berlin-Buch and 188 in Heidelberg. The results suggest that neutron therapy for bronchial carcinoma can be a good alternative in curative and palliative situations in the early stages. (author). 14 refs.

    Maxillary sinus carcinomas are rare malignancies of the face, characterized by high local relapsing rate. Modalities of treatment are without consensus and respective roles of radiation therapy and surgery remain controversial. As those malignancies are often diagnosed at locally advanced stage, radiation therapy may frequently be used for patients having unresectable advanced disease. Nevertheless, surgery remains treatment of choice for more localized malignancies, in association with systematic postoperative radiotherapy. For those patients whose prognosis remains pejorative, it is necessary to precise the role of radiotherapy in first intention for inoperable tumors, to define necessity for nodal treatment performing and evaluate the place of neo-adjuvant or concomitant chemotherapy in a multimodal strategy.

    Radiotherapy is an essential treatment for many patients with head and neck squamous cell carcinoma. Its association with molecular targeted therapies represents a real progress. Among the recent advances in the molecular targeted therapy of cancer, the applications centred on E.G.F.R. are currently the most promising and the most advanced at clinical level. Considering the set of therapeutic tools targeting E.G.F.R., there are at present two well-identified emerging categories of drugs with monoclonal antibodies, on the one hand, and tyrosine kinase inhibitors, on the other. In many preclinical studies, the combination of anti-E.G.F.R. drugs with irradiation has led to additive or supra-additive cytotoxic effects. Furthermore, anti-angiogenic agents have shown promising results in association with anti-E.G.F.R. drugs and radiotherapy. This research effort has recently produced encouraging clinical results in advanced head and neck cancer with combination of cetuximab (an anti-E.G.F.R. monoclonal antibody) with irradiation with a significant impact on patient survival. Active and efficient clinical research is currently ongoing to determine the place of molecular targeted therapies in the treatment of head and neck cancer, particularly in association with radiotherapy.

    The authors evoke some characteristics of the basal cell carcinoma (slow evolution, local morbidity) and report and discuss the case of a giant basal cell trunk carcinoma, associated with several symptoms (pain, bleeding, anaemia), already metastatic at the moment of diagnosis, and locally treated by irradiation. Due to its size and expansion, this carcinoma was considered as inoperable. An external radiotherapy has been performed and resulted in a significant clinical tumour reduction. But the metastatic risk is high in such cases. Radiotherapy is then a therapeutic option for a local treatment with a durable efficiency. Short communication

    Purpose. - To identify prognostic factors and treatment toxicity in a series of epidermoid cancers of the anal canal without evident metastasis. Patients and methods. - Between June 1972 and January 1997, 305 patients (pts) were treated with curative-intent radiation therapy (RT). The T-stages according to the 1987 UICC classification were: 26 T1, 141 T2, 104 T3, and 34 T4. There were 49 pts with nodal involvement at presentation. Pretreatment anal function scoring according to our in-house system was: 22 scored 0, 182 scored 1, 74 scored 2, 7 scored 3. 11 scored 4, and 9 not available pts. The treatment started with external beam RT (EBRT) in 303 pts (median dose: 45 Gy). After a rest period of 4 to 6 weeks, a boost of 20 Gy was delivered by EBRT in 279 pts and by interstitial {sup 192}Ir brachytherapy (Bcy) in 17 pts. Seven pts received only one course of EBRT (mean dose: 49.5 Gy) and 2 pts were treated with interstitial {sup 192}Ir Bcy alone (55 and 60 Gy, respectively). concomitant chemotherapy (5-fluoro-uracil and either mitomycin C or cisplatin) was delivered to 19 pts. Mean follow-up was 103 months. Results. - At the end of RT local tumor clinical complete response (cCR) rate was 80%. Out of 61 non responders or local progressive tumors 27 (44%) were salvaged with abdomino-perineal resection (APR). The rate of local tumor relapse (LR) was 12%. Out of 37 LTR, 20 (54%) were salvaged with APR and one with interstitial {sup 192}Ir Bcy. The overall local tumor control (LC) rate with or without salvage local treatment was 84%. LC rate with a good anal function scoring (score 0 and 1) was 56.5%0. Among 181/186 available pts who preserved their anus, 94% had a good anal function scoring. For a subgroup of 15 pts with length tumor <2 cm-N0, the LC rate after the end of RT was 100% the LC rate with or without local salvage treatment was 100%, and among 13 available pts who preserved their anus, the anal function scoring was good in 12 pts (92%). The 10-years disease-free survival was 74%. After multivariate analysis, 3 independent predicting factors significantly influenced the disease-free survival: gap duration between 2 courses of RT (>38 days vs {<=}38 days, P=0.0025), pretreatment anal function scoring (0 vs 1 vs 2 vs 3 vs 4, P =4.4 10{sup -6}), and cCR after the end of RT (no complete response vs complete response, P =2.5 10{sup -14}). Conclusion. - We confirm excellent results with RT in T1 and T2 lesions. However, chemoradiotherapy should be preferred to improves survival free. of colostomy with a good anal sphincter function for tumors more than or equal to 2 cm in length and locally advanced tumors.

    Purpose. - To assess the feasibility and efficacy of accelerated postoperative radiation therapy (RT) in patients with squamous-cell carcinoma of the head and neck (SCCHN). Patients and methods. - Between December 1997 and July 2001, 68 patients (male to female ratio: 52/16; median age: 60-years (range: 43-81)) with pT1-pT4 and/or pN0-pN3 SCCHN (24 oropharynx, 19 oral cavity, 13 hypopharynx, 5 larynx, 3 unknown primary, 2 maxillary sinus, and 2 salivary gland) were included in this prospective study. Postoperative RT was indicated because extra-capsular infiltration (ECT) was observed in 20 (29%), positive surgical margins (PSM) in 20 (29%) or both in 23 patients (34%). Treatment consisted of external beam R 66 Gy in 5 weeks and 3 days. Median follow-up was 15 months. Results. -According to CTC 2.0, acute morbidity was acceptable: grade 3 mucositis was observed in 15 (22%) patients, grade 3 dysphagia in 19 (28%) patients, grade 3 skin erythema in 21 (31%) patients with a median weight loss of 3.1 kg (range: 0-16). No grade 4 toxicity wa observed. Median time to relapse was 13 months; we observed only three (4%) local and four (6%) regional relapses, whereas eight (12%) patients developed distant metastases without any evidence of locoregional recurrence. The 2 years overall-, disease-free survival, an actuarial locoregional control rates were 85, 73 and 83% respectively. Conclusion.- The reduction of the overall treatment time using postoperative accelerated RT with weekly concomitant boost (six fraction per week) is feasible with local control rates comparable to that of published data. Acute RT related morbidity is acceptable. (author)

    As muco-epidermoid carcinomas are the most frequent tumours of salivary glands for child, the authors report the study of the role of radiotherapy. This study is based on a survey performed in 34 paediatric departments. The authors analyse the age and gender, the use of irradiation, the tumour location, the tumour grade and size, the use of surgery and of radiotherapy, and survival. Radiotherapy is beneficial for high grade tumours, but cannot be recommended for low and intermediate grades. Short communication

    Objective To study the expression of p16, cyclin D1, Rb and phosphorylated Rb(Ser795) in the esophageal squamous cell carcinoma. Methods Immunohistochemistry was performed and analysed on 34 cases of paraffin-embedded tissues. Results The expression of phosphorylated Rb(Ser795) was positively correlated to that of cyclin D1 (r=0.401, P=0.021) and inversely to that of p16 (r=-0.348, P=0.044). In stepwise regression and the best subset regression, the expression of p16 (P=0.034) and phosphorylated Rb(Ser795) (P=0.030) were the only determinants of the mitotic index. Conclusion The expression of phosphorylated Rb(Ser795) could be considered as a mark of the interaction between p16 and cyclin D1. The detection of phosphorylated Rb, p16 and cyclin D1 will be possibly helpful to the oncogenesis investigation on the esophageal carcinoma.

    The authors report a work aimed at assessing the feasibility and toxicity of a re-irradiation treatment in stereotactic conditions using CyberKnife and cetuximab in the case of local relapses of epidermoid cancers of the ORL sphere. Thirty three patients have been submitted to this treatment between June 2007 and April 2009. Although six patients died by six months, this treatment seems to be a good alternative, and presents an acceptable short-term toxicity. Further studies are needed to compare this technique to other therapeutic techniques, and to assess the risk of long term complications. Short communication

    Radio-induced tumor have been known for a long time to occur after treatment of cancer during childhood. This entity is exceptional following radiotherapy of the cavum. Skull and facial osteosarcoma were described after treatment of UCNT. We report two observations of radio-induced tumors arising respectively three and seven years after treatment of UCNT. The first one is a temporo-parietal glioblastoma and the second is a rhino- and pharyngeal myxoma. The two patients are alive after treatment of the second tumor. The delay of appearance of these tumors, their situation in the field's irradiated and dose received suggests their radioinduced nature. However, the cytogenetic study is necessary to confirm the implication of radiotherapy in the genesis of these cancers. (authors)

    The sentinel lymph node (SLN) is the first lymph node draining the tumour. Aim of the study: To determine the negative predictive value of the SLN in the NO or NI squamous cell carcinomas (SCC) of the oral cavity or the oropharynx. Materials and method: SLN localization firstly requires a lymphoscintigraphy which is realised after four injections of radiolabelled colloids around the tumour. This scintigraphy allows a cutaneous marking of the SLN. Per operative detection of the SLN is performed with a detection probe. Results: One or more SLN have been localized in 20 of the 21 patients. No SLN was found in one patient whose tumour was a recurrence. (T2 NO MO) of a SCC of the oropharynx irradiated 3 years before. The failure rate of the method is 4,8% (1 false negative in 21 patients) and the false negative rate is 12,5% (1 false negative in 8 positive patients). This false negative patient had a T3 NO MO SCC of the oropharynx with a SLN found in level III, deep lateral cervical group. The neck dissection revealed one positive node in level lb, submandibular group, and 27 other nodes, all negative. The probability for the whole neck dissection to be negative when the SLN is negative (negative predictive value), is 92,3% (12/13) in our study. Conclusion: Our patient population is too small to obtain statistically significant conclusions. A maximum of 2 % of false negative patients is necessary to apply this method and avoid complete neck dissection in NO and NI tumours of the the oral cavity and the oropharynx with a negative SLN.

    Occurrence of basal cell carcinoma (BCC) following radiotherapy for tinea capitis is well known. The aim of this study was to specify the clinical and histological features of these BCC seen in 33 patients (1995 000). Twenty seven men and six women were diagnosed with BCC. The age of onset varied between 32 an 62 years. Radiotherapy was received between 5 and 17 years of age. The interval between irradiation and the onset of carcinoma varied between 21 and 51 years. Total number of lesions was 55. Forty percent of BCC occurred on the occipital area, the number varied from 1 to 5 and the size from 2 to 45 mm. Clinically, the nodular type was found in 51% of cases. Pigment was present in 64% of cases. Histological study showed a nodular aspect in 76% and pigmentation in 63% of cases. Nodular and pigmented type were the predominant BCC occurring after radiotherapy for tinea capitis in our series. In the literature, BCC are the most frequent carcinomas occurring after radiotherapy (70-100%). Pigmentation was not described in other series. The nodular histological form was the most frequent.

    Full Text Available ACC is a rare malignant tumor that affects most commonly the major and minor salivary glands and rarely the paranasal sinuses, lacrimal gland, larynx, ear, vulva, and so forth. The maxillary sinus when affected is considered having a poor prognosis due to delayed diagnosis and delayed treatment credited to its slow spread, late symptoms, and complex anatomy which hampers surgical resection. The expressions of tumor markers too have a significant role in determining the prognosis. The treatment of choice consists of wide radical resection of the tumor followed by radiotherapy. Rehabilitation options in cases with huge maxillary defects still need further exploration.

    In the department of nuclear medicine at Ibn Sina university hospital. Thyroid carcinoma follow-up strategy has been modified and includes cervical ultrasonography and thyroglobulin measurement. The role of radio-iodine scanning in the management of differentiated thyroid carcinoma is decreasing. Papillary and follicular carcinoma have good prognosis but late metastases exist and can lead to death. A lifelong follow-up is therefore mandatory. The main goal of follow-up is to detect earlier persistent or recurrent disease. (authors)

    Purpose. - While some patients presenting with hepatocellular carcinoma (HCC) benefit from curative therapies (transplantation, surgery, percutaneous ablation), others are only candidates for palliative options such as chemo-embolization or symptomatic care. Although conventional external-beam radiotherapy of the liver is regarded as little efficient and potentially toxic in cirrhotic patients, 3-dimensional conformal radiotherapy (CRT), by decreasing the amount of normal liver included in the radiation portal, allows dose escalation to occur without increasing the risk of radiation-induced hepatitis. This trial was designed to assess the efficacy and tolerance of CRT for small-size HCC in cirrhotic patients. Patients and methods. - Prospective phase II trial including stage A/B cirrhotic patients with small-size HCC not suitable for curative treatments; CRT consisted in a standard fractionation radiation, with a total dose of 66 Gy. Results. - Twenty-seven patients were included, 15 of whom had previously been treated for HCC; mean age was 68. Among the 23 assessable patients, 18 (78%) presented with complete response, 3 (13%) with partial response, and 2 with no response. Acute complications occurred in 24 patients, and were mainly acceptable (grade 1/2: 22 patients, grade 3/4: 11 patients, 4 (15%) of whom had clinical and/or hematological toxicities). Only 2 (9%) grade 3/4 clinical and/or hematological late toxicities are reported. Conclusion. - CRT is a non-invasive curative technique highly suitable for small-size HCC in cirrhotic patients; further investigations are needed to compare it to the other available treatments, and to integrate it into the curative therapeutic algorithm of HCC.

    Patients suffering from locally advanced unresectable squamous cell carcinoma of the oropharynx and hypopharynx treated with radiotherapy alone have a poor prognosis. More than 70% of patients die within 5 years mainly due to local recurrences. The aim of this study was to evaluate retrospectively the Antoine Lacassagne Cancer Center's experience in a treatment by concomitant bid radiotherapy and chemotherapy. Evaluation was based on analysis of the toxicity, the response rates, the survival, and the clinical prognostic factors. From 1992 to 2000, 92 consecutive patients were treated in our single institution. All of them had stage IV, unresectable squamous cell carcinoma of the pharynx and they received continuous bid radiotherapy (two daily fractions of 1.2 Gy, 5 days a week, with a 6-h minimal internal between fractions). Total radiotherapy dose was 80.4 Gy on the oropharynx and 75.6 Gy on the hypopharynx. Two or three chemotherapy courses of cisplatin (CP)-5-fluorouracil (5FU) were given during radiotherapy at 21 -day intervals (third not delivered after the end of the radiotherapy). CP dose was 100 mg/m{sup 2} (day 1) and 5-FU was given as 6-day continuous infusion (750 mg/m{sup 2}/day at 1. course; 430 mg/m{sup 2}/day at 2. and 3. courses). Special attention was paid to supportive care, particularly in terms of enteral nutrition and mucositis prevention by low-level laser energy. Acute toxicity was marked and included WHO grade III/IV mucositis (89%, 16% of them being grade IV), WHO grade III dermatitis (72%) and grade III/IV neutropenia (61%). This toxicity was significant but manageable with optimised supportive care, and never led to interruption of treatment for more than 1 week, although there were two toxic deaths. Complete global response rate at 6 months was 74%. Overall global survival at 1 and 3 years was 72% and 50% respectively, with a median follow-up of 17 months. Prognostic factors for overall were the Karnofsky index (71% survival at 3 years for patients with a Karnofsky index of 90-100% versus 30% for patients with a Karnofsky index of 80% versus 0% for patients with a Karnofsky index of 60-70%, p = 0.0001) and tumor location (55% at years for oropharynx versus 37% for pan-pharynx versus 28% for hypopharynx, p=0.009). These results confirm the efficacy of concomitant bid radiotherapy and chemotherapy in advanced unresectable tumor of the pharynx. The improvement in results will essentially depend on our capacity to restore in a good nutritional status the patients before beginning this heavy treatment. (author)

    It is a prospective study in order to evaluate the feasibility and the toxicity of a chemotherapy by docetaxel, cisplatin and 5-fluoro-uracil followed by a concomitant chemoradiotherapy in the treatment of non metastatic locally evolved undifferentiated carcinomas of the cavum. The conclusion was despite the low number of patients in our series, the observed results show that this neoadjuvant chemotherapy followed by a concomitant chemoradiotherapy in the locally evolved undifferentiated carcinomas of the cavum is feasible. however, the high acute toxicity needs the use of conformal irradiation techniques. Besides, a longer follow up is necessary to evaluate the therapy efficiency and the delayed toxicity of this protocol. (N.C.)

  4. Should the pulmonary scintigraphy of pre-surgery examination of bronchial carcinomas be made at rest or under effort?; La scintigraphie pulmonaire du bilan pre-operatoire des carcinomes bronchiques doit elle etre realisee au repos ou a l`effort?

    One of the key elements in deciding whether a patient, bearing a bronchial carcinoma, should be subject to a surgery is the predicted value of the post-surgery maximal exhaled volume per second (MEVS), usually determined by means of an at-rest pulmonary perfusion scintigraphy. At the same time, this parameter remains rather badly correlated to mortality and peri-surgical morbidity. The goal of this study was to determine whether under-effort pulmonary perfusion scintigraphy, i.e. in peri-surgical conditions gives different results in this case. Twenty patients bearing bronchial carcinoma have benefited by a pulmonary scintigraphy, successively, in the end of an exercise on ergo-metric bicycle and at rest. Two mCi of Tc-labelled macro-aggregate albumin were injected after effort, then 10 mCi one hour later, at rest. The homo-lateral lung perfusion to tumor, expresses in % of total pulmonary perfusion (% TP), was reduced at rest (-8 {+-} 6%) and at effort (-10 {+-} 8%), in comparison with the normal values. On the analysis of ensemble of population (43 {+-} 7% vs 41 {+-} 9%, NS) the % TP did not changed significantly between the at-rest and under-effort acquisitions. At the same time, 4 patients presented important variation, amounting up to 20% of total pulmonary perfusion: the % TP increased in 2 cases and decreased in the other 2 cases. In conclusion, in the patients bearing bronchial carcinoma, the relative perfusion of tumoral lung varies under effort in a non-negligible number of cases (4/20). Additional studies are necessary to establish the value of under-effort pulmonary scintigraphy, in the evaluation of the post-surgery respiratory functional capacity

    The authors report a case of gastric, renal, pulmonary, and myocardial uptake of M.D.P.-Tc 99 m in a patient with parathyroid carcinoma. Parathyroid carcinoma is a rare cause of primary hyperparathyroidism which becomes complicated during its evolution by metastatic calcifications. Metastatic calcifications are frequently located in lungs and heart. If an adequate treatment is not undertaken, these calcifications progress and evolve into severe respiratory and cardiac complications. In our patient, quasi-complete disappearance of metastatic calcifications on the follow-up bone scintigraphy, performed four weeks after surgical cure of parathyroid tumour, indicates the great interest of this examination in early identification of metastatic calcifications and monitoring of their disappearance after treatment.

    Purpose. Using deformable registration methods from a phase two clinical study of air breath control during radiotherapy in patients suffering from severe respiratory insufficiency and non-small cell lung carcinoma. Patients and methods, Between April 2002 and November 2005, 22 patients with severe respiratory insufficiency were treated with curative intent by conformal therapy combined with active breathing control. Results. After a mean of follow-up of 22 months, the local control rate is 28% and the method is feasible despite the severe respiratory insufficiency. However the overall survival is still poor due to metastatic widespread. For the second part of the study, the clinical protocol was also used for two studies using deformable registration methods. In the first study, a deformable registration method has been developed in order to register several breath-hold 3D CT of the same patient acquired at several days of interval. It allowed quantifying the inter-fraction breath-hold reproducibility by analysing the resulting displacement field. For 6 patients, the breath-hold was effective, while for 2 patients, motion greater than 10 mm were detected. The second study aimed to simulate 4D images from 3D breath-hold images. Developing an ad-hoc methodology based on the interpolation of 3D dense deformation fields performed it. The approach has been validated with expert selected landmarks, with accuracy lower than 3 mm. Conclusion. ABC is feasible, even in case of severe insufficiency respiratory syndrome but metastatic widespread disease is still a major challenge even with an acceptable local control rate without serious side effects: regarding the deformable registration method. Such artificial 4D images could allow decreasing the dose need to acquire a full 4D image, to simulate irregular breathing pattern and to be used for 4D dosimetry planning. (author)

    Nasopharyngeal carcinoma (NPC) is a highly radiosensitive and chemo-sensitive. In the patient with locally advanced tumours, the results of conventional radiotherapy are unsatisfactory with significant rates of both local recurrences and distant metastases. The aim of this review is to report the innovative strategies for treatment of the nasopharyngeal carcinoma. Altered fractionation techniques can improve local control. The impact of the innovative techniques, including conformal radiation, stereotactic radiation and IMRT, on survival, must be evaluated in randomized trials. The encouraging early results obtained with concurrent (more than sequential) chemotherapy and radiotherapy must be confirmed in prospective randomized trial in endemic areas. (authors)

Results are discussed in terms of response, steadiness, advancement, grade 3 and 4 toxicity, and side effects. The therapeutic efficiency corresponds to an objective response rate of 77 per cent, and tolerance profile seems to be acceptable for patients suffering from locally advanced cardia and oesophagus cancer.

    Full Text Available RACIONAL: A escolha da forma de tratamento do carcinoma de células escamosa de esôfago ainda hoje é orientada pelo estadiamento tumoral, onde as características histopatológicas do tumor são o maior determinante. Parale-lamente, desenvolvem-se estudos para entender o comportamento da biologia tumoral por método imunoistoquímico de quantificação manual, avaliando a ati-vidade proliferativa ou apoptótica do tecido em análise. As desvantagens conti-das no modo manual fizeram surgir e desenvolver método computadorizado de análise de imagem. OBJETIVOS: Verificar as expressões dos marcadores KI-67 e Caspase-3 e correlacioná-las com as características clínico-patológicas do tumor. MÉTODOS: Foram estudados 29 blocos parafinados provenientes de pa-cientes portadores de carcinoma de células escamosas de esôfago submetidos à esofagectomia e pertencentes a acervos de laboratórios de patologia. Proce-deu-se preparo das lâminas por técnica imunoistoquímica convencional. A quantificação da imunorreatividade às proteínas Ki-67 e Caspase-3 foi realizada pelo software de análise de imagem computadorizada SAMBA (Systeme d'Analyse Microphotometrique a Balayage Automatique através do índice de marcagem encontrado. RESULTADOS: Predominaram na amostra o sexo mascu-lino (82,7%; maiores de 50 anos; tumores moderadamente diferenciados (68,98%; estágio III (72,42%; lesões >3cm e localizadas no ⅓ inferior do ór-gão. Os índices médios de marcagem identificados foram de 62,05% para o Ki-67 e 86,06% para a Caspase-3, e não mostraram correlação com as caracterís-ticas clínico-patológicas como sexo, idade, estadiamento tumoral, grau de pro-fundidade da lesão e comprometimento linfonodal. Houve significante diferença de expressão do Ki-67 entre os graus histológicos (P=0,047 e correlação entre os índices dos marcadores estudados (r=0,41 e P =0,032. CONCLUSÃO: Na presente investigação as atividades das proteínas estudadas se mostraram in-tensas sendo que a da Caspase-3 foi superior ao Ki-67 mas sem correlação com as características clínico-patológicas.BACKGROUND: The esophageal squamous cell carcinoma treatment strategy is still based on the tumor staging, where tumor histopathologic charac-teristics are the major determinants. In parallel, studies have been developed in order to better understand the tumor biology using immunohistochemical meth-ods with manual quantification evaluating the proliferative and apoptotic activi-ties of the cells. The disadvantages related to the manual method rose the de-velopment of computerized ways to do the image analysis. OBJETIVES: To verify the expressions of the markers Ki-67 (proliferative and Caspase-3 (apoptotic and to correlate them with the clinic and pathologic characteristics of the tumor. METHODS: Twenty-nine paraffin embedded blocks were studied, each one con-taining tissue samples from patients with esophageal squamous cell carcinoma submitted to esophagectomies. The clinic and pathological data were obtained from histopathologic informations and from medical records. The slides were prepared following the routine immunohistochemical method until the point to utilize the specific antibodies (MIB-1 and CPP32. Positive quantification of the immunoreactivity to the proteins Ki-67 and Caspase-3 was performed by the software for computerized image analysis SAMBA (Systeme d' Analyse Micro-photometrique a Balayage Automatique. Statistical analysis was done having P3cm; and lesions located in the lower third of the organ. The mean score indexes found were 62.05% for Ki-67 and 86.06% for Caspase-3 and there was no correlation with the clinic or pathologi-cal characteristics as gender, age and tumor staging. There was significant dif-ference of Ki-67 expression among the histological grades (P=0.047 and corre-lation between the evaluated indexes (r=0.41 and P=0.032. CONCLUSION: The protein expressions were high and the Caspase-3 protein activity was higher than the Ki-67, without correlation with clinic or pathological characteristics as gender, age, tumor staging, grade of lesion depth and lymph node invasion.

    Aim of the study: To investigate the therapeutic impact of additional cervical dedicated {sup 18}F.D.G.-PET-CT on the management of head and neck squamous cell carcinoma (H.N.S.C.C.). Materials and methods: Thirty patients with H.N.S.C.C. underwent a [{sup 18}F]-F.D.G.-PET-CT standard, whole-body scan completed by a cervical dedicated protocol. Two physicians blindly reviewed the exams and the results were discussed with surgeons to determine the therapeutic impact of the dedicated protocol. Result: Among 30 patients, only four (13%) discordant results were registered by the both observers, and two more by only one observer (k = 0.75, S.D. = 0.08). As to the four patients: 1) a N0 staged patient on whole body (W.B.) exam was upstaged to N2b in cervical PET (obese patient, whole-body exam with poor quality), 2) for a second patient, no node was described on whole-body scan, but one lymph node in each cervical chain was observed in focused PET, with low standardized uptake value (S.U.V. value), 3) in the other two cases, cervical PET scan upstaged from N2a to N2b and from N2a to N2c (S.U.V. < 3), without any influence on treatment management. Conclusion: Our results show that additional cervical dedicated PET-CT does not modify the management of patients with H.N.S.C.C. when compared to whole-body PET-CT, except for particular obese or N0 patients, allowing to reduce patient CT radiation dose and time-consuming PET acquisition.

    IntroductionAvec plus de 7000 cas diagnostiqués par an en Belgique, le cancer bronchique est l’un des cancers les plus fréquents chez l'homme. Son pronostic est très réservé, la survie à 5 ans tous stades confondus étant inférieure à 15 %. Ce faible taux de guérison s’explique en grande partie par le fait que le diagnostic se réalise généralement à un stade avancé de la maladie. Une méthode de détection précoce, l’endoscopie en autofluorescence, exploite des variations de la fluorescence bron...

    As the human papillomavirus (HPV) is at the origin of 25% of upper aero-digestive tract cancers, and as these tumours present an increased radio-sensitivity compared to other tumours, probably due to a greater transcriptional activity of p53, the authors report the study on the influence of a decrease of the expression of the APP-BP1 in these tumours which could favour a radio-induced apoptosis. By using a reverse transcriptase polymerase chain reaction (RT-PCR), they assessed the APP-BP1 expression levels as well as expression levels of transcriptions coding onco-proteins known to be over-expressed in HPV+ tumours. They compared the radio-sensitivities of HPV+ and HPV- cells, the first one appearing to be greater than the second one. Short communication

    Background Renal cell carcinoma is well known for its frequency to metastasise, particularly to lungs, liver, bones and brain. Metastasis to the skin is much less common. Presentation as a result of the skin lesion is even more unusual, with only 14 previously reported cases in the English literature. The majority of these cases have been reported in patients with recurrent disease or with other metastases. Case presentation We present only the second case of non-recurrent renal cell carcinom...

    Background It has been hypothesized that human cytomegalovirus (HCMV) may be associated with breast cancer progression. However, the role of HCMV infection in breast cancer remains controversial. We aimed to assess whether HCMV genes (UL122 and UL83) could be detected in breast carcinomas and reinvestigated their possible association with breast cancer progression. DNA from paraffin-embedded tissues was analyzed by real-time PCR. We investigated 20 fibroadenomas and 27 primary breast carcinom...

    OBJECTIVES: Our aim is to investigate the expression of kit protein (KIT) and epidermal growth factor receptor (EGFR) in parotid carcinomas in order to correlate the expression to histology and prognosis. Further we want to perform mutation analysis of KIT-positive adenoid cystic carcinomas....... PATIENTS AND METHODS: Formalin-fixed paraffin-embedded sections from 73 patients with parotid gland carcinomas were used for the study. The sections were stained with both KIT and EGFR polyclonal antibodies. Twelve KIT-positive adenoid cystic carcinomas were examined for c-kit mutation in codon 816....... RESULTS: Of all carcinomas 25% were KIT-positive and 79% were EGFR-positive. Ninety-two percentage of the adenoid cystic carcinomas were KIT-positive. None of the adenoid cystic carcinomas had mutations in codon 816 of the c-kit gene. CONCLUSION: Neither KIT- nor EGFR-expression seem to harbour...

    2009-12-01

    Full Text Available The aim of this work was to study the immunohistochemical expression of androgen receptor, estrogen receptor and progesterone receptor in pleomorphic adenomas, Warthin's tumors, mucoepidermoid carcinomas and adenoid cystic carcinomas of salivary glands. A total of 41 pleomorphic adenomas, 30 Warthin's tumors, 30 mucoepidermoid carcinomas and 30 adenoid cystic carcinomas were analyzed, and the immunohistochemical expression of these hormone receptors were assessed. It was observed that all cases were negative for estrogen and progesterone receptors. Androgen receptor was positive in 2 cases each of pleomorphic adenoma, mucoepidermoid carcinoma and adenoid cystic carcinoma. In conclusion, the results do not support a role of estrogen and progesterone in the tumorigenesis of pleomorphic adenomas, Warthin's tumors, mucoepidermoid carcinomas and adenoid cystic carcinomas. However, androgen receptors can play a role in a small set of salivary gland tumors, and this would deserve further studies.
