    2010-01-01

    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. PMID:21047402

    André Del Negro

    Full Text Available CONTEXT: Adenoid cystic carcinomas are malignant tumors that occur in both the major and the minor salivary glands. A laryngeal location is rare because of the paucity of accessory salivary glands in this area. Adenoid cystic carcinomas account for less than 1% of all malignant tumors in the larynx, and only about 120 cases have been reported in the literature. These tumors have a slight female predisposition, and their peak incidence is in the fifth and sixth decades of life. In this article, we describe a case of laryngeal adenoid cystic carcinoma and discuss its clinical characteristics and treatment. CASE REPORT: We report on a case of laryngeal adenoid cystic carcinoma in a 55 year-old female patient who presented with dyspnea and hoarseness. Features of the diagnostic and therapeutic evaluation are described and the clinical management of such cases is outlined. The clinical course, definitive treatment strategy and surgical procedure, and also adjuvant treatment with irradiation are discussed. Although the tumor is radiosensitive, it is not radiocurable.

    Adenoid cystic carcinoma of the breast is a rare neoplasm, accounting for only 0.1% of all malignant breast tumours. It is more common in women in the sixth decade of their lives and often in the sub areolar area. The clinical criteria is not specific and the radiographic examination showed a benign-appearing tumour. The preoperative diagnosis is possible with fine-needle aspiration cytology. The diagnosis is made by histological examination, presented a difficult differential diagnosis with cribriform carcinoma; so it is necessary to use histochemical or immunohistochemical techniques. The treatment is not well established. It consists of lumpectomy with radiation or mastectomy. Compared to other locations, adenoid cystic carcinoma of the breast has a favorable prognosis. Lymph node involvement or distant metastases seldom occur. The aim of our study is to describe the epidemiological, clinico pathological characteristics, the treatment and the prognosis of this rare type of breast tumour. (authors)

    Malignant tumors of the larynx are extremely rare in children and adolescents. Adenoid cystic carcinoma accounts for less than 1% of all malignant tumors in the larynx. We presented a 16-year-old girl with subglottic adenoid cystic carcinoma, whose symptoms of prolonged and exacerbating dyspnea had been attributed to asthma at another medical center. Indirect flexible and rigid laryngoscopy revealed a smooth mass in the subglottic region occupying 80% of the airway passage. The lesion was also confirmed by both CT and MRI. There was no lymphadenopathy in the neck. The patient was successfully treated by surgery and postoperative radiotherapy. Pathological staging was T4N0M0 according to the AJCC, 2003. During six years of follow-up, there was no evidence for local recurrence or regional and distant metastasis.

    Adenoid cystic carcinoma (ACC) are uncommon tumors, representing about 10% to 15% of head and neck tumors. We compare the survival and control rates at our institution with those reported in the literature, and examine putative predictors of outcome. All patients registered with the tumor registry as having had ACC were identified. Demographic and survival variables were retrieved from the database. Additionally, a chart review of all patients was done to obtain specific information. Minor gland tumors were staged using the American Joint Committee on Cancer's criteria for squamous cell carcinomas in identical sites. Histopathologic variables retrieved included grade of the tumor, margins, and perineural invasion. Treatment modalities, field sizes, and radiation doses were recorded in applicable cases. An effort to retrieve archival tumor specimens for immunohistochemical analysis was undertaken. A total of 69 patients were treated for ACC from 1955 to 1999. One patient, who presented with fatal brain metastasis, was excluded from further analysis. Of the remaining 68 patients, 30 were men and 38 were women. The average age at diagnosis was 52 years, and mean follow-up was 13.2 years. Mean survival was 7.7 years. Overall survival (OS) rates at 5, 10, and 15 years were 72%, 44%, and 34%, and cause-specific survival was 83%, 71%, and 55%, respectively. Recurrence-free survival rates were 65%, 52%, and 30% at 5, 10, and 15 years, with a total of 29 of 68 (43%) eventually suffering a recurrence. Overall survival was adversely affected by advancing T and AJCC stage. Higher tumor grades were also associated with decreased OS, although the numbers compared were small. Primaries of the nasosinal region fared poorly when compared with other locations. Total recurrence-free survival, local and distant recurrence rates were distinctly better in primaries of the oral cavity/oropharynx when compared with those in other locations. Reduced distant recurrence-free survival was

    Full Text Available Introcuction: Adenoid cystic carcinoma (ACC is the second most common salivary glands tumor and the most common malignant tumor of minor salivary glands and also submandibular glands; however ACC of the larynx and trachea is rare. These tumors generally present in subglottic region as smooth submucosal solid mass without ulceration. Their primary symptoms are often as respiratory problems. Materials and Methods: This study was done on a woman, 54 years, with subglottic ACC that presented with exertional dyspnea, stridor, cough and hoarseness. After confirmation of diagnosis with biopsy, the patient underwent a total laryngectomy and then postoperative radiotherapy. Conclusion: During one year follow up, the patient did not show any evidence of local recurrence or distant metastasis. Surgery with free margins in combination with postoperative radiotherapy was recommended to treat laryngeal ACC in order to obtain better survival.

    Adenoid cystic carcinoma is a malignant minor salivary gland tumor that represents laryngeal tumors. The submucosal location of laryngeal adenoid cystic carcinoma (LACC) results in delayed presentation. Here, we present the first systematic review of reported cases of LACC to determine trends in presentation, diagnostic and treatment modalities, and patient outcome. PubMed, Web of Science, MEDLINE, and EMBASE databases. A search of the above databases was done to identify articles reporting cases of LACC. The variables included in the analysis were patient demographics, presenting symptoms, tumor location, imaging, treatment, follow-up time, recurrence, and outcome. A total of 50 articles and 120 cases were included in the review. The most common presenting symptom was dyspnea (48.8%), followed by hoarseness (43.9%). LACC arose most frequently from the subglottis (56.7%). At presentation, 14.6% (13 of 89) of patients had regional disease. The average follow-up time was 54.0 months. At follow-up, distant metastasis was reported in 30 cases (33.3%). Surgery alone (43.3%) and surgery with radiotherapy (43.3%) were used most frequently and resulted in 57.1% and 55.3% of patients alive with no evidence disease at follow-up, respectively. LACC was most often located in the subglottis. Patients commonly presented with dyspnea and hoarseness. In this systematic review, surgery with radiotherapy and surgery alone were the most commonly employed treatment modalities, and both resulted in slightly more than 50% of patients alive with no evidence of disease at follow-up. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    The authors retrospectively assessed the usefulness of postoperative radiation therapy after local resection of adenoid cystic carcinoma, with emphasis on organ-conserving treatment and the cosmetic results. Between 1985 and 1995, 32 patients underwent local resection followed by postoperative radiation therapy with curative and organ-conserving intent. None of patients received any form of chemotherapy as part of their initial treatment. Radiation therapy was carried out by techniques that were appropriate for the site and extension of each tumor. The 5-year local control, disease-free, and overall survival rates of all patients were 76%, 68%, and 86%, respectively. The 5-year local control rate and disease-free survival rate of patients with microscopically positive margins were 89% and 75%, respectively, and higher than in patients with macroscopically residual disease, but no significant difference in 5-year overall survival rate was observed. The postoperative cosmetic results in 29 patients with head and neck lesions were evaluated. No difference was documented between the cosmetic results postoperatively setting and after postoperative radiotherapy, and no significant differences in cosmetic results were observed according to radiation dose. The combination of local resection with organ-conserving intent and postoperative radiation therapy provided good cosmetic results in patients with T1 or T2 lesions. Postoperative radiation therapy with smaller fractions is useful, because good local control can be achieved in patients with adenoid cystic carcinoma having microscopically positive margins without inducing any late adverse reactions. However, the number of patients was too small and the follow-up period was too short to draw any definite conclusion in regard to fraction size. A much longer follow-up study with a larger number patients will be required to accurately determine the optimal treatment intensity and duration of treatment. (K.H.)

    Full Text Available Adenoid cystic carcinoma of uterine cervix is a rare tumor. Its origin is debatable. It has a high incidence in postmenopausal women but rarely can develop in patients under 40. An association with squamous cell carcinoma has been described. We report a case of adenoid cystic carcinoma of the endocervical canal with foci of squamous cell carcinoma in a 34-year-old suffering from menorrhagia associated with blood-stained vaginal discharge. Per vaginum and per speculum examination revealed a growth. Cervical biopsy showed bits of tissue, suggesting adenoid cystic carcinoma. Patient was operated upon and uterus with cervix sent for histopathological examination. We report this case because of its rarity, particularly in young patients, with description of illustrative pathology and discussion on the histological diagnosis.

    Multilocular cystic renal cell carcinoma (MCRCC) is a subtype of clear cell renal cell carcinoma and has mild clinical symptoms and a favorable prognosis. Accordingly, nephron-sparing surgery is recommended as a therapeutic strategy. If histologic subtype of MCRCC can be predicted preoperatively with an acceptable level of accuracy, it may be important in predicting prognosis and make clinical management. Most MCRCCs show characteristic cross-sectional imaging findings and permit accurate diagnosis before the treatment. Cross -sectional imaging of MCRCC reveals a well -defined multilocular cystic mass with irregularly enhanced thickened septa and without enhanced intracystic solid nodule. It is often classified as Bosniak classification Ⅲ , which is significantly different from that of other renal cystic masses. The clinical, pathologic, and radiologic features of MCRCC were discussed and illustrated in this article. The role of the imaging preoperative evaluation for MCRCC, and management implications were emphasized. (authors)

    Adenoid cystic carcinoma is a malignant salivary gland tumor with typical histologic patterns. The majority of the se tumors occurs in the minor salivary glands, especially mucosa of the hard palate. The authors experienced the patients, who complained the tumor-like soft tissue masses on the palatal and mouth floor area. After careful analysis of clinical, radiological and histopathological findings, we diagnosed them as adenoid cystic carcinomas in the minor salivary glands, obtained results were as follows : 1. Main clinical symptoms were a slow growing soft tissue mass with normal intact mucosa on the palatal area, and soft tissue mass with mild pain on the mouth floor area. 2. In the radiographic examinations, soft tissue masses were observed with invasion to adjacent structures, and moderate defined, heterogeneous soft tissue mass with enhanced margin, respectively. 3. In the histopathologic examinations, dark-stained, small uniform ballad's cells in the hyaline or fibrous stroma were observed as solid and cribriform patterns, respectively.

    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) [es

    Adenoid cystic carcinoma (ACC) of the sublingual gland is an extremely rare neoplasm. The clinicopathological characteristics of ACC are slow-growing swelling with or without ulceration, perineural spread, local recurrence, and distant metastasis. This report describes a 58-year-old male who had a slowly growing swelling without ulceration on the right side of the mouth floor that had been present for 1 month. In a radiological examination, the mass showed multilocular cystic features and no bony or tongue muscle invasion. No enlarged cervical lymph nodes were detected. Excisional biopsy and histological analysis showed that the lesion was ACC. In addition to reporting a rare case of ACC, this report also discusses the differential diagnosis and treatment of ACC with a review of the relevant literature.

    Early diagnosis and treatment of the respiratory and gastrointestinal complications of cystic fibrosis (CF) have led to improved survival with many patients living beyond the fourth decade. Along with this increased life expectancy is the risk of further disease associated with the chronic manifestations of their condition. We report a patient with documented CF related liver disease for which he was under routine surveillance that presented with histologically proven hepatocellular carcinoma (HCC). It is important that physicians are aware of this association as increased vigilance may lead to earlier diagnosis and perhaps, a better outcome.

    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.

    2000-01-01

    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

  12. Mitochondrial mutations in adenoid cystic carcinoma of the salivary glands.

    Suhail K Mithani

    Full Text Available BACKGROUND: The MitoChip v2.0 resequencing array is an array-based technique allowing for accurate and complete sequencing of the mitochondrial genome. No studies have investigated mitochondrial mutation in salivary gland adenoid cystic carcinomas. METHODOLOGY: The entire mitochondrial genome of 22 salivary gland adenoid cystic carcinomas (ACC of salivary glands and matched leukocyte DNA was sequenced to determine the frequency and distribution of mitochondrial mutations in ACC tumors. PRINCIPAL FINDINGS: Seventeen of 22 ACCs (77% carried mitochondrial mutations, ranging in number from 1 to 37 mutations. A disproportionate number of mutations occurred in the D-loop. Twelve of 17 tumors (70.6% carried mutations resulting in amino acid changes of translated proteins. Nine of 17 tumors (52.9% with a mutation carried an amino acid changing mutation in the nicotinamide adenine dinucleotide dehydrogenase (NADH complex. CONCLUSIONS/SIGNIFICANCE: Mitochondrial mutation is frequent in salivary ACCs. The high incidence of amino acid changing mutations implicates alterations in aerobic respiration in ACC carcinogenesis. D-loop mutations are of unclear significance, but may be associated with alterations in transcription or replication.

    Full Text Available Adenoid cystic carcinoma is rare and usually arises in the salivary glands. It grows slowly, but is characterized by easy perineural invasion with local infiltration and distant metastasis. In metastatic setting, the efficacy of intravenous chemotherapy is limited. Herein, we report one male patient who had a advanced, inoperable adenoid cystic carcinoma with lung metastasis, presenting with right buccal unhealed ulcer, pain and poor intake, whose loco-regional tumors responded dramatically after intra-arterial chemotherapy and his symptoms were almost completely relieved. We also make a literature review for treatment of adenoid cystic carcinoma.

    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.

    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

    Full Text Available A 37-year-old male athlete was diagnosed with primary tracheal adenoid cystic carcinoma following investigation for dyspnea, wheeze, and eventual stridor. Preoperative bronchoscopy revealed a highly vascular tumor 4 cm distal to the cricoid with no gross disease extending to the carina. Imaging revealed circumferential tracheal irregularity immediately inferior to the cricoid, with no definite cricoid invasion. Locoregional extension of disease was noted invading the thyroid and abutment of the carotid approximately 180°. Intraoperative findings identified tracheal mucosal disease extending distal to the carina and proximally at the cricothyroid joints where bilateral functional recurrent nerves were preserved. A decision made to preserve the larynx given the inability to fully resect distal tracheal disease. A 5 cm sleeve resection of the trachea was made with a cricotracheal anastomosis following suprahyoidal muscle release and laryngeal drop-down. The patient was treated with adjuvant radiotherapy including platinum based chemotherapy in an effort to maximise local control. PET scanning three months after therapy revealed no FDG uptake locally or distally.

    2013-09-01

    Full Text Available Background: High-grade transformation or dedifferentiation in carcinoma is progression of a low-grade malignant neoplasm to a high-grade carcinoma or poorly differentiated adenocarcinoma. This is rarely observed in adenoid cystic carcinoma of the salivary glands. Case Report: A 39 year-old woman presented with a painless mass at the left submandibulary region that had been growing slowly for 5 years. Submandibulary mass resection revealed a mass with peripheral adenoid cystic carcinoma and a central high-grade tumor delineated with a fibrous rim, raising the possibility of a hybrid or composite carcinoma, requiring differential diagnosis depending upon morphology and immunohistochemistry findings. The final histopathological diagnosis was high-grade transformation of adenoid cystic carcinoma. After surgical therapy, the patient was irradiated to the neck and submandibulary region. No sign of tumor recurrence has been evident for 36 months. Conclusion: This present case seems to be another rare case with high-grade transformation of adenoid cystic carcinoma and the fibrous rim may be a histopathological feature of such cases, which should be kept in mind.

    Adenoid cystic carcinomas (ACC) and, to a lesser extent, cutaneous squamous cell carcinomas and basal cell carcinomas may exhibit perineural invasion (PNI). A subset of patients have tumors with extensive PNI tracking to the skull base that are incompletely resectable and are treated with definitive radiotherapy (RT). RT may be administered with intensity-modulated RT or proton RT. Patients with ACC may also be considered for neutron RT, although the number of available neutron facilities is ...

    Metastatic carcinoma to the pancreas is uncommon and head and neck squamous carcinoma metastatic to the pancreas is extremely rare. Metastatic squamous cell carcinoma to the pancreas presents a unique diagnostic challenge: in addition to mimicking the rare primary squamous cell carcinoma of the pancreas based on cytologic, histologic, and immunohistochemical features, it may be mistaken for a cystic neoplasm of the pancreas because of its high predilection for cystic degeneration in metastatic sites. Herein, we report a case of tonsillar squamous cell carcinoma with a cystic pancreatic metastasis diagnosed by ultrasound-guided fine needle aspiration biopsy (EUS-FNA). This represents a third reported case of metastatic squamous cell carcinoma to the pancreas from the head and neck region. Metastatic squamous cell carcinoma should be considered in the differential diagnosis of EUS-FNA during evaluation of pancreatic cystic lesion. © 2017 Wiley Periodicals, Inc.

    The incidence of an adenoid cystic carcinoma on major salivary glands is low, constituting only about 10% to 15% of all parotid malignancies. Cases of delayed metastasis have been reported, but reports of specific renal involvement have not been extensively found. We present the case of a 21-year-old woman with a left renal metastasis from an adenoid cystic carcinoma of the parotid gland that had been surgically treated 7 years previously. The patient underwent successful left radical nephrectomy. During follow-up, the patient developed pulmonary nodules that were metastatic adenoid cystic carcinoma and were surgically excised. At last follow-up, the patient was doing well with no evidence of disease.

    2008-01-01

    Purpose: To analyze the recent experience of patients with adenoid cystic carcinoma treated with radiation therapy at Memorial Sloan-Kettering Cancer Center. Methods and Materials: From 1990 to 2004, a total of 59 patients with a diagnosis of primary adenoid cystic carcinoma of the head and neck received radiation therapy at our institution. The subsite distribution was oral cavity, 28% (n = 17); paranasal sinuses, 22% (n = 13); parotid, 14% (n = 8); submandibular, 14% (n = 8); oropharynx, 10% (n = 6); sublingual, 3% (n = 2); nasopharynx, 3% (n = 2); and other, 5% (n = 3). T Stage distribution was T1, 34% (n = 20); T2, 19% (n = 11); T3, 14% (n = 8); and T4, 34% (n = 20). Twenty-nine percent of patients (n = 17) were treated with intensity-modulated radiation therapy; 25% (n =15), with three-dimensional conformal therapy, and the remainder, with conventional techniques. Ninety percent (n = 53) of patients received treatment including the base of skull. Results: Median follow-up for surviving patients was 5.9 years. Five-year and 10-year rates of local control and distant metastases-free survival were 91%/81% and 81%/49%, respectively. Five-year and 10-year rates of disease-free and overall survival were 76%/40% and 87%/65%, respectively. On univariate analysis, stage T4 (p = 0.004) and gross/clinical nerve involvement (p = 0.002) were associated with decreased progression free survival, whereas stage T4 and lymph node involvement were associated with decreased overall survival (p = 0.046 and p < 0.001, respectively). Conclusions: Radiation therapy in combination with surgery produces excellent rates of local control, although distant metastases account for a high proportion of failures. Routine treatment to the base of skull reduces the significance of histologic perineural invasion, but major nerve involvement remains an adverse prognostic factor

    Full Text Available Background: Cystic papillary thyroid carcinoma (CPTC is a variant of papillary carcinoma that has many mimickers in cytological grounds. Aim: To study the cytomorphologic features of CPTC and compare them to those of other cystic thyroid lesions using fine-needle aspiration cytology (FNAC. We also aimed to identify the cytomorphologic features that distinguish CPTC from other cystic thyroid lesions. Materials and Methods: Seventy-three cases of CPTC were included in the study. The cytomorphologic features of these cases were analyzed. The FNA smears of other thyroid lesions with cystic changes (300 colloid goiters, 290 adenomatoid nodules, 11 follicular neoplasms, and 9 hurtle cell neoplasm were also studied. Results: The smears in CPTC revealed isolated follicular cells, small groups of cells with scalloped margins, cell swirls, small clusters with a cartwheel pattern, papillary clusters, intranuclear inclusions, nuclear grooves, sticky colloid, intracellular colloids, psammoma bodies, multinucleated giant cells, and foamy and hemosiderin laden macrophages. Small groups of cells with scalloped borders, cellular swirls, and small clusters with a cartwheel pattern were seen in CPTC, but not in other cystic lesions. Interestingly, mesothelial-like cells and hemophagocytic cells were seen in five and three cases of CPTC, respectively, but not in other cystic lesions. Conclusion: Mesothelial-like cells and hemophagocytic cells were observed in five and three cases of CPTC, respectively. Similar finding have not been previously reported in the literature.

    2013-01-01

    Background Malignant tumours of minor salivary glands are uncommon, representing only 2-4% of all head and neck cancers. In the larynx, minor salivary gland tumours rarely occur and constitute less than 1% of laryngeal neoplasm. Most of the minor salivary gland tumours arise in the subglottis; however, they can also occur in the supraglottis, in the false vocal cords, aryepiglottic folds and caudal portion of the epiglottis. The most common type of malignant minor salivary gland tumour is adenoid cystic carcinoma. Methods We present a unusual case of adenoid cystic carcinoma of glottic-subglottic region in a 61-year-old woman. Follow-up endoscopy and laryngeal magnetic resonance imaging (MRI) at three years after treatment showed no recurrence of the tumour. Results The diagnosis of glottic-subglottic adenoid cystic carcinoma should be considered in patients who are characterized by dyspnea, cough and stridor, but do not respond to pharmacologic approach. Conclusions Adenoid cystic carcinoma is usually a very slow growing cancer, invested by an apparently normal laryngeal mucosa, so that it can show no clear symptoms for a long time. For these reasons the increasing number of diagnostic mistakes or late diagnosis that may be fatal in some cases. PMID:24427787

    Adenoid cystic carcinoma is among the most frequent malignancies in the salivary and lacrimal glands and has a grave prognosis characterized by frequent local recurrences, distant metastases, and tumor-related mortality. Conversely, adenoid cystic carcinoma of the breast is a rare type of triple-negative (estrogen and progesterone receptor, HER2) and basal-like carcinoma, which in contrast to other triple-negative and basal-like breast carcinomas has a very favorable prognosis. Irrespective of site, adenoid cystic carcinoma is characterized by gene fusions involving MYB, MYBL1, and NFIB, and the reason for the different clinical outcomes is unknown. In order to identify the molecular mechanisms underlying the discrepancy in clinical outcome, we characterized the phenotypic profiles, pattern of gene rearrangements, and global microRNA expression profiles of 64 salivary gland, 9 lacrimal gland, and 11 breast adenoid cystic carcinomas. All breast and lacrimal gland adenoid cystic carcinomas had triple-negative and basal-like phenotypes, while salivary gland tumors were indeterminate in 13% of cases. Aberrations in MYB and/or NFIB were found in the majority of cases in all three locations, whereas MYBL1 involvement was restricted to tumors in the salivary gland. Global microRNA expression profiling separated salivary and lacrimal gland adenoid cystic carcinoma from their respective normal glands but could not distinguish normal breast adenoid cystic carcinoma from normal breast tissue. Hierarchical clustering separated adenoid cystic carcinomas of salivary gland origin from those of the breast and placed lacrimal gland carcinomas in between these. Functional annotation of the microRNAs differentially expressed between salivary gland and breast adenoid cystic carcinoma showed these as regulating genes involved in metabolism, signal transduction, and genes involved in other cancers. In conclusion, microRNA dysregulation is the first class of molecules separating adenoid

    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.

    Full Text Available Adenoid cystic carcinoma (ACC is a rare malignant tumor that affects the head and neck region. It is a malignant tumor arising from minor salivary glands, palate being the most common intraoral location, usually affecting individuals of the fifth decade. This tumor generally has a slow growth rate, and it is often present for several years before the patient seeks treatment. We report a case of extensive ACC involving palate, extending to a maxillary sinus in a young lady.

    Full Text Available A 60-year-old male patient came to ENT OPD with complaints of left nasal obstruction from the last 5 years and moderate quantity of epistaxis from the last 4 months. It was associated with foul smelling mucopurulent rhinorrhea. On clinical examination, a fleshy mass was seen occupying the posterior part of left nasal cavity and displacing the septum on the right side. The mass was relatively painful, soft, and bleeding on touch. The provisional diagnosis of "vascular-tumor-like" angiofibroma was suspected. Diagnostic nasal endoscopy and CT scan PNS were done which revealed a mass occupying the left nasal cavity arising from the posterior part of septum along the choanae till the anterior part of sphenoid sinus. Biopsy of the same revealed an adenoid cystic carcinoma. Adenoid cystic carcinoma is uncommon and that too of the nasal cavity. The cases of the adenoid cystic carcinoma involving the nasal cavity usually involves the lateral wall and the involvement of the posterior part of nasal septum is extremely rare. Thus the presentation of this uncommon disease is discussed here.

    Hyperthyroidism is rarely associated with malignancy, but it cannot rule out thyroid cancer. Although there is published data describing this coexistence, thyroid carcinomas inside autonomously functioning nodules are uncommon. A 49-year-old woman presented with a cervical mass, unexplained weight loss and anxiousness, sweating and insomnia. On physical examination, she had a palpable left thyroid nodule. Thyroid function tests showed suppressed TSH (nodule. 99mTC thyroid scintigraphy showed a hyperfunctioning nodule with suppression of the remainder parenchyma. Fine-needle aspiration cytology was nondiagnostic (cystic fluid). The patient was started on thiamazole 5 mg daily with subsequent normalization of thyroid function, but she developed cervical foreign body sensation and a left hemithyroidectomy was performed. Histology showed a 4 cm cystic nodule with a follicular variant papillary carcinoma and the patient underwent completion thyroidectomy, followed by radio-iodine ablation. Published literature showed an increased prevalence of autonomously functioning nodules, harbouring thyroid carcinomas in adults. Papillary carcinoma is the most frequently described but the follicular variant is rare. Although rare, thyroid cancer is not definitively excluded in hyperthyroid patients and it should always be considered as differential diagnosis. Copyright © 2018. Published by Elsevier Ltd.

    Purpose: This study sought to review a single-institution experience with the management of adenoid cystic carcinoma of the head and neck. Methods and Materials: Between 1960 and 2004, 140 patients with adenoid cystic carcinoma of the head and neck were treated with definitive surgery. Ninety patients (64%) received postoperative radiation to a median dose of 64 Gy (range, 54-71 Gy). Distribution of T stage was: 26% T1, 28% T2, 20% T3, and 26% T4. Seventy-eight patients (56%) had microscopically positive margins. Median follow-up was 66 months (range, 7-267 months). Results: The 5- and 10-year rate estimates of local control were 88% and 77%, respectively. A Cox proportional hazards model identified T4 disease (p = 0.0001), perineural invasion (p = 0.008), omission of postoperative radiation (p = 0.007), and major nerve involvement (p = 0.02) as independent predictors of local recurrence. Radiation dose lower than 60 Gy (p = 0.0004), T4 disease (p 0.005), and major nerve involvement (p = 0.02) were predictors of local recurrence among those treated with surgery and postoperative radiation. The 10-year overall survival and distant metastasis-free survival were 64% and 66%, respectively. Conclusion: Combined-modality therapy with surgery followed by radiation to doses in excess of 60 Gy should be considered the standard of care for adenoid cystic carcinoma of the head and neck

    The patient is a previously healthy 52-year-old woman who presented with dyspepsia for two months. Multiple imaging modalities including ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) showed diffuse bile duct dilatation with an obstructive lesion of the distal extrahepatic biliary duct (EHD) as well as two masses in the peripancreatic area. The peripancreatic masses appeared cystic with posterior acoustic enhancement on ultrasound, low density on CT imaging, and high signal intensity on T2-weighted MRI. The lesion in the distal EHD exhibited similar characteristics on CT and MRI. A Whipple procedure was performed and histological specimens showed malignant cells with large mucin pools that was consistent with a diagnosis of colloid carcinoma of the EHD with metastatic lymphadenopathies. Colloid carcinoma, also called mucinous carcinoma, is classified as a histologic variant of adenocarcinoma. Because the colloid carcinoma of the biliary tree is exceedingly rare, the imaging characteristics and the clinical features of colloid carcinoma remain relatively unknown. We report a case of colloid carcinoma of the common bile duct and its accompanied metastatic lymphadenopathies with characteristic imaging findings reflecting abundant intratumoral mucin pools

    Adenoid cystic carcinoma is a rare malignancy, usually found in the salivary glands, although this unusual tumor can be found at other sites of the body. In particular, regarding adenoid cystic carcinoma of the cervix (ACCC) most frequently reports are given for postmenopausal women. In this respect, our work is one among very few in the literature that considers a cytologic picture of this uncommon cervix carcinoma. The case of 74 year old patient with postmenopausal bleeding is described. Both Pap smear and air dried smear of the uterine cervix were analyzed. The cytologic findings revealed very few small clusters of abnormal glandular cells, as well as some amorphous eosinophilic globule-like material, with granulomatous and necrotic background. The latter includes a lot of histiocytes, multinucleated giant cells, large aggregates of epitheloid cells and lymphocytes. Histology revealed the diagnosis of ACCC. We emphasize the importance of careful screening of Pap smear that might be crucial in the case of suspicious clinical findings in postmenopausal women, when the possibility of ACCC has to be considered.

    Most metastatic lymph nodes from head and neck malignancy are solid. Cystic nodes are found in 33% - 61% of carcinomas arise from Waldeyer's ring, of which only 1.8% - 8% originate are from the nasopharynx. Some cystic cervical metastases were initially presumed to be branchial cleft cyst. This case report aims to highlight the unusual presentation of cystic cervical metastasis secondary to nasopharyngeal carcinoma in a young adult. The histopathology, radiological features and management strategy were discussed. A 36-year-old man presented with a solitary cystic cervical swelling, initially diagnosed as branchial cleft cyst. Fine needle aspiration yielded 18 ml of straw-coloured fluid. During cytological examination no atypical cells were observed. Computed tomography of the neck showed a heterogeneous mass with multiseptation medial to the sternocleidomastoid muscle. Histopathological examination of the mass, post excision, revealed a metastatic lymph node. A suspicious mucosal lesion at the nasopharynx was detected after repeated thorough head and neck examinations and the biopsy result confirmed undifferentiated nasopharyngeal carcinoma. Cystic cervical metastasis may occur in young patients under 40 years. The primary tumour may not be obvious during initial presentation because it mimicks benign branchial cleft cyst clinically. Retrospective review of the computed tomography images revealed features that were not characteristic of simple branchial cleft cyst. The inadequacy of assessment and interpretation had lead to the error in diagnosis and subsequent management. Metastatic head and neck lesion must be considered in a young adult with a cystic neck mass.

    Adenoid cystic carcinoma (AdCC) is a malignant salivary gland tumor. To date, no cases of AdCC in first-degree relatives have been reported in the literature. We present a 50-year-old female (Case 1) and this patients' father (Case 2), both of whom were diagnosed with AdCC of the minor salivary...... 18 germline variants in common between Case 1 and Case 2. However, none of the variants were associated with AdCC or other head and neck cancers. To our knowledge, we present the first potential case of familial AdCC. The presented genetic data may contribute to further investigations...

    Two cases of severe tracheal stenosis due to advanced nonresectable adenoid cystic carcinoma of the trachea were reported. Case 1 was a 38-year-old male who underwent emergency {sup 60}Co irradiation following endoscopic YAG laser irradiation. This approach was quite effective. Proton irradiation was effective against tumor recurrence. Case 2 was a 28-year-old female in whom emergency treatment for tracheal obstruction due to edema after laser therapy necessitated transient tracheal intubation. The tracheal stenosis due to recurrent tumor after {sup 60}Co irradiation was improved by insertion of an intraluminal permanent stent. (author).

    Full Text Available Adenoid Cystic Carcinoma (ACC is uncommonly found outside the major or minor salivary glands and is especially rare when located in nasal cavity. A case report of 13 year old boy who presented with mass in nasal cavity and epistaxis is presented here. Endoscopic removal of mass was done and histopathology revealed ACC. ACCs are slow growing tumours with a propensity for frequent local recurrence and early perineural and haematogenous spread. Early diagnosis requires a high index of suspicion for this rare pathology.

    The initial and follow-up CT and MRI images of ten patients with hepatic metastases from ovarian tumors were retrospectively analyzed to establish their features and sequential changes in appearance. Ten patients with hepatic metastasis from ovarian tumors received initial and follow-up CT and MRI examinations. Six patients were followed up every two to three weeks before surgical tumor resection. Both CT and MR images were analyzed by two radiologists. A total of fourteen lesions were detected by CT and MRI in 10 patients. All 14 lesions were demonstrated as areas of marked hyperintensity on T2-weighted MRI. Eleven cyst-like tumors were demonstrated as round or oval low density lesions on CT and as areas of hypointensity on T1-weighted imaging. Three lesions were shown as solid masses with slightly low attenuation at the initial CT examination and slightly low or iso-intensity areas on T1-weighted imaging, and these lesions showed early peripheral globular enhancement and delayed enhancement on contrast-enhanced CT and MR imaging. Cystic formation was observed two to three weeks later after initial study in all the 3 solid lesions. Rapid subcapsular effusion, which showed obvious enhancement on delayed Gd-DTPA enhanced MR imaging, was observed in two patients. The hepatic metastatic tumor from cystic ovarian carcinoma may manifest as a well-defined cystic lesion or as a solid mass, and the solid mass shows delayed enhancement on contrast-enhanced CT and MR imaging. Furthermore, rapid cystic formation and rapid subcapsular extension is frequently seen. (author)

    Spindle cell carcinoma of the breast is a rare tumor. This tumor can proliferate rapidly and cause cystic changes because of internal tissue necrosis. We evaluated a 54-year-old woman with right breast lump. Mammography showed a category four mass with a diameter of 2.5 cm. Ultrasonography (US) revealed a complex cystic lesion, and fine-needle aspiration (FNA) cytology demonstrated bloody fluid and malignant cells. Partial breast resection and sentinel lymph node biopsy were performed. Immunohistology revealed spindle cells with positive results for cytokeratin (AE1/AE3) and vimentin, partially positive results for s-100, and negative results for desmin and α-actin. The pathological stage was IIA, and biochemical characterization showed that the tumor was triple negative. Six courses of FEC-100 chemotherapy (5-fluorouracil 500 mg/m 2 , epirubicin 100 mg/m 2 , and cyclophosphamide 500 mg/m 2 ) were administered. Radiotherapy was performed. This case is discussed with reference to the literature

    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

    Translocation events are frequent in cancer and may create chimeric fusions or ‘regulatory rearrangements’ that drive oncogene overexpression. Here we identify super-enhancer translocations that drive overexpression of the oncogenic transcription factor MYB as a recurrent theme in adenoid cystic carcinoma (ACC). Whole-genome sequencing data and chromatin maps reveal distinct chromosomal rearrangements that juxtapose super-enhancers to the MYB locus. Chromosome conformation capture confirms that the translocated enhancers interact with the MYB promoter. Remarkably, MYB protein binds to the translocated enhancers, creating a positive feedback loop that sustains its expression. MYB also binds enhancers that drive different regulatory programs in alternate cell lineages in ACC, cooperating with TP63 in myoepithelial cells and a Notch program in luminal epithelial cells. Bromodomain inhibitors slow tumor growth in ACC primagraft models in vivo. Thus, our study identifies super-enhancer translocations that drive MYB expression and provides insight into downstream MYB functions in the alternate ACC lineages. PMID:26829750

    Adenoid cystic carcinoma (AdCC) of the salivary glands is characterized by MYB-NFIB or MYBL1-NFIB fusion, prolonged but relentlessly progressive clinical course with frequent recurrences, and development of distant metastasis resulting in high long-term mortality. Currently, no effective therapy...... is available for patients with advanced non-resectable and/or metastatic disease. Complicating the clinical management of this patient group is the lack of prognostic markers. The purpose of this study is to investigate the prognostic value of 1p36 loss in patients with AdCC. The presence of 1p36 deletion...... and gene fusions involving the MYB, NFIB, and MYBL1 genes in a cohort of 93 salivary gland AdCCs was studied using fluorescence in situ hybridization. These results were statistically correlated with clinical data and outcome. Deletion of 1p36 in AdCC was identified in 13 of 85 analyzable cases (15...

    Extracellular matrix metalloproteinase inducer (EMMPRIN) is a transmembrane glycoprotein that is involved in tumor invasion by stimulating matrix metalloproteinase (MMP) expression. Our previous immunohistochemical study found that the expression of EMMPRIN in salivary adenoid cystic carcinoma (SACC) was positively correlated with tumor perineural and perivascular invasion. The present study was designed to further investigate the role of EMMPRIN in the invasion of SACC. Western blot results showed that EMMPRIN was upregulated in the highly metastatic SACC cell line SACC-LM, compared to SACC-83, a SACC cell line with low metastatic ability. Blocking of EMMPRIN by its antibody significantly decreased the adhesion, secretion of MMP-2 and MMP-9, and invasion activity of SACC-LM cells in vitro (PEMMPRIN may play an important role in the invasion of SACC by stimulating the expression of MMP-2 and MMP-9 in tumor and stromal 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.

    To investigate the expression of ErbB-3 binding protein-1 (EBP-1), matrix metalloproteinase 9 (MMP-9) and E-cadherin (E-cad) in adenoid cystic carcinoma and their correlation. Immunohistochemistry(PV6000 method) was used to detect EBP-1, MMP-9 and E-cad expression in 66 cases of adenoid cystic carcinoma tissues and matched para-cancerous normal tissues. In this study all cases were successfully followed up. The positive expression rate of EBP-1 in adenoid cystic carcinoma tissues was 85%. EBP-1 expression was significantly correlated to pathological pattern and clinical stage (P correlation between EBP-1 and E-cad expression, and positive correlation between EBP-1 and MMP-9. EBP-1 and its correlation with MMP-9 and E-cad may be used as useful indicators for clinical assessment of tumor biological behavior and prognosis in patients with adenoid cystic carcinoma.

    The separation of branchial cleft cysts from metastatic cystic squamous cell carcinomas in adults can be clinically and cytologically challenging. Diagnostic accuracy for separation is reported to be as low as 75% prompting some authors to recommend frozen section evaluation of suspected branchial cleft cysts before resection. We evaluated 19 cytologic features to determine which were useful in this distinction. Thirty-three cases (21 squamous carcinoma and 12 branchial cysts) of histologically confirmed cystic lesions of the lateral neck were graded for the presence or absence of 19 cytologic features by two cytopathologists. The cytologic features were analyzed for agreement between observers and underwent multivariate analysis for correlation with the diagnosis of carcinoma. Interobserver agreement was greatest for increased nuclear/cytoplasmic (N/C) ratio, pyknotic nuclei, and irregular nuclear membranes. Recursive partitioning analysis showed increased N/C ratio, small clusters of cells, and irregular nuclear membranes were the best discriminators. The distinction of branchial cleft cysts from cystic squamous cell carcinoma is cytologically difficult. Both digital image analysis and p16 testing have been suggested as aids in this separation, but analysis of cytologic features remains the main method for diagnosis. In an analysis of 19 cytologic features, we found that high nuclear cytoplasmic ratio, irregular nuclear membranes, and small cell clusters were most helpful in their distinction. Diagn.

    Adenoid cystic carcinoma (ACC) of the breast is a rare type of breast cancer, which presents inconsistencies in the optimal management strategy. A retrospective review of prospectively collected data, spanning the last 20 years, was performed using the cancer registry database at our institution. Six patients were diagnosed with ACC of the breast, out of 5,813 total patients diagnosed with breast cancer (0.1%). Our identified patients had a median age of 66, all with the early stage cancer (Stage I/II). The average size of the breast lesion was 1.62 cm, and nodal status was negative for all cases. All patients had resection as primary therapy (partial or total mastectomy), with one patient also undergoing external beam radiation and tamoxifen hormonal therapy. Median follow-up was 85 months, with all patients being disease-free at last follow-up. ACC of the breast has an indolent course, despite triple negative status. Our study suggests that radiation may not be warranted and confirms the rarity of axillary node metastases, indicating that sentinel node excision may also not be necessary. Ultimately, the hope is that our findings along with the reviewed literature will aid in determining the most appropriate options for management of ACC of the breast.

    Adenoid cystic carcinoma is among the most frequent malignancies in the salivary and lacrimal glands and has a grave prognosis characterized by frequent local recurrences, distant metastases, and tumor-related mortality. Conversely, adenoid cystic carcinoma of the breast is a rare type of triple......-negative (estrogen and progesterone receptor, HER2) and basal-like carcinoma, which in contrast to other triple-negative and basal-like breast carcinomas has a very favorable prognosis. Irrespective of site, adenoid cystic carcinoma is characterized by gene fusions involving MYB, MYBL1, and NFIB, and the reason...... for the different clinical outcomes is unknown. In order to identify the molecular mechanisms underlying the discrepancy in clinical outcome, we characterized the phenotypic profiles, pattern of gene rearrangements, and global microRNA expression profiles of 64 salivary gland, 9 lacrimal gland, and 11 breast...

    Full Text Available Adenoid cystic carcinoma (ACC is one of the most common salivary gland malignant tumors with a high risk of recurrence and metastasis. Current studies on cancer stem cells (CSCs have verified that CSCs are the driving force behind tumor initiation and progression, suggesting that new cancer therapies may be established by effectively targeting and killing the CSCs. The primary goal of this study is to investigate the expression patterns of ABCG2, CD133, and podoplanin in ACC of minor salivary glands by immunohistochemistry analysis. We found that ABCG2 was weakly expressed in normal looking salivary gland tissues. A significant upregulation of ABCG2 expression in ACC was observed with a similar expression pattern of Ki-67. CD133 was detected in apical membrane of epithelial cells and podoplanin was expressed positively in myoepithelial cells of both normal looking tissue and ACC. However, no significant difference was found of the expression pattern of CD133 and podoplanin between normal looking tissues and ACC. Our observations suggest that CSCs may exist in quiescent cells with ABCG2 positive staining, which are surrounded by cells with positive expression of ABCG2 and Ki-67 in ACC, and costaining with ABCG2 and Ki-67 may help predict the location of CSCs.

    Adenoid cystic carcinoma (ACC) in the larynx is an extremely rare entity. Although the 5-year disease-specific survival rates for laryngeal ACC are high, distant metastasis might occur up to more than 5 years post treatment. Therefore patients with ACC require long-term follow-up. To summarize the characteristics of laryngeal ACC by analyzing six cases in a single center. This was a retrospective analysis of six patients with laryngeal ACC who were treated in Beijing Tongren Hospital between 1998 and 2013. The mean age at diagnosis was 44 years, ranging from 15 to 61 years. Dyspnea was the most common complaint. All patients underwent combined-modality treatment with surgical resection and external beam radiation. The range of follow-up time varied from 1 to 7 years (median 5 years). Follow-up inspections indicated that none of them had local or regional recurrence. Distant metastasis occurred in 33.7% (2/6) of the patients, with one lung metastasis 5 years after operation and one liver metastasis 4 years after operation.

    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.

    Vorinostat is a histone deacetylase inhibitor (HDACi). Based on a confirmed partial response (PR) in an adenoid cystic carcinoma (ACC) patient treated with vorinostat in a prior phase 1 trial, we initiated this phase 2 trial. Vorinostat was administered orally 400 mg daily, 28 day cycles. The primary objective was to evaluate response rate (RR). Exploratory studies included whole exome sequencing (WES) of selected patients. Thirty patients were enrolled. Median age of patients was 53 years (range 21-73). Median number of cycles was 5 (range 1-66). Lymphopenia (n = 5), hypertension (n = 3), oral pain (n = 2), thromboembolic events (n = 2) and fatigue (n = 2) were the only grade 3 adverse events (AEs) that occurred in more than 1 patient. Eleven patients were dose reduced secondary to drug-related AEs. Two patients had a partial response (PR), with response durations of 53 and 7.2 months. One patient had a minor response with a decrease in ascites (for 19 cycles). Stable disease was the best response in 27 patients. Targeted and WES of 8 patients in this trial identified mutations in chromatin remodeling genes highlighting the role of the epigenome in ACC. Vorinostat demonstrated efficacy in patients with ACC supporting the inclusion of HDACi in future studies to treat ACC.

    Full Text Available Background : Mexico′s National Institute of Respiratory Diseases (NIRD is a third-level national reference center. 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.

    Purpose: To examine the efficacy of fast neutron radiotherapy for the treatment of locally advanced and/or recurrent adenoid cystic carcinoma of the head and neck and to identify prognostic variables associated with local-regional control and survival. Methods and Materials: One hundred fifty-nine patients with nonmetastatic, previously unirradiated, locally advanced, and/or recurrent adenoid cystic carcinoma (ACC) of the head and neck region were treated with fast neutron radiotherapy during the years 1985-1997. One hundred fifty-one patients had either unresectable disease, or gross residual disease (GRD) after an attempted surgical extirpation. Eight patients had microscopic residual disease and were analyzed separately. Sixty-two percent of patients had tumors arising in minor salivary glands, 29% in major salivary glands, and 9% in other sites such as the lacrimal glands, tracheal-bronchial tree, etc. Fifty-five percent of patients were treated for postsurgical recurrent disease and 13% of patients had lymph node involvement at the time of treatment. The median duration of follow-up was 32 months (range 3-142 months). Actuarial curves for survival, cause-specific survival, local-regional control, and the development of distant metastases are presented for times out to 11 years. Results: The 5-year actuarial local-regional tumor control rate for the 151 patients with GRD was 57%; the 5-year actuarial overall survival rate was 72%; and the 5-year actuarial cause-specific survival rate was 77%. Variables associated with decreased local-regional control in the patients with GRD as determined by multivariate analysis included base of skull involvement (p < 0.01) and biopsy only versus an attempted surgical resection prior to treatment (p = 0.03). Patients without these negative factors had an actuarial local-regional control rate of 80% at 5 years. Patients with microscopic residual disease (n = 8) had a 5-year actuarial local-regional control rate of 100%. Base of

    Objective: To describe the cytologic features of adenoid cystic carcinoma (ADCC) of salivary glands, and to identify distinguishing cytologic features of ADCC and basal cell adenoma (BCA). Methods: A retrospective review of cytology smears of 30 cases of ADCC and 12 cases of BCA of salivary glands were performed. All cases were collected from Beijing Tongren Hospital, Capital Medical University from January 2010 to January 2017. Except for 2 aspirate smears of ADCC, all were touch imprint smears. All cases had further histological confirmation. Results: Neoplastic ductal cells of ADCC were arranged in three-dimensional clusters, sheets and singles. Hyaline globules were found in most cases (20/30, 66.7%). The nuclei were round to oval, showing varying degrees of nuclear atypia. These included (1) the nuclei were hyperchromatic, demonstrating coarse or slightly coarse, irregularly distributed chromatin; (2) the nuclei were slightly large and vary in size; (3) appearance of the nuclei had a different degree of irregularity (often mild). Nucleoli were common seen (21/30, 70.0%), and were prominent in some cases. Mitosis and necrosis were rare. Cytologically, BCA showed cell arrangements and nuclear features overlapped with those of ADCC. The cytologic difference between these two tumors included: (1) the tumor cells presented rarely in singles; (2) hyaline globules were very uncommon (1/12) in BCA; (3) nuclei of BCA were hypochromatic or slightly hyperchromatic, homogeneous and uniform in appearance and size, overall without nuclear atypia and they were smaller and slender then those of ADCC and (4) individual cells of BCA showed relatively abundant cytoplasm. Conclusions: The cytologic features of ADCC and BCA both overlap and different from each other. Most cases can be diagnosed by cytologic examination. The presence of hyaline globules is an important diagnostic clue of ADCC, although not pathognomonic. Nuclear atypia of neoplastic ductal cells is an essential

    Salivary adenoid cystic carcinoma (SACC) is the most frequent salivary gland malignancy with a unique characteristic that has been named perineural invasion (PNI). EMMPRIN is a transmembrane glycoprotein that has been demonstrated to promote PNI in SACC. Slug, one of the most effective promoters of the epithelial-to-mesenchymal transition (EMT), has been found to be associated with PNI in SACC. The aim of the present study was to investigate the roles and relationships of Slug, EMMPRIN, and E-cadherin in the PNI process of SACC. The expression levels of Slug, EMMPRIN, and E-cadherin in 115 primary SACC cases were statistically analyzed by immunohistochemistry. Simultaneously, the SACC cell line SACC-83 was transfected with recombinant plasmids of silencing Slug (si-Slug) and/or silencing EMMPRIN (si-EMMPRIN). The functions of Slug and EMMPRIN in the EMT and PNI process were assessed by reverse transcription PCR (RT-PCR), western blotting, morphological observation, scratch test, migration assay, and in vitro perineural invasion assay. The immunohistochemical statistics revealed that the high expression of Slug and EMMPRIN and the low expression of E-cadherin were significantly associated with the PNI of SACC (P EMMPRIN expression (P EMMPRIN expression were both significantly negatively associated with E-cadherin expression (P EMMPRIN silencing both significantly inhibited EMMPRIN expression but promoted E-cadherin expression in SACC-83 cells (P EMMPRIN, or both induced cell morphology changes and inhibited tumor cell motility and PNI ability in SACC-83 cells (P EMMPRIN and then upregulating E-cadherin in the PNI process of SACC. The present study indicated that Slug and EMMPRIN are potential biomarkers and therapeutic targets for the diagnosis and treatment of PNI in human SACC.

    Provirus integration site for Moloney murine leukemia virus 1 (Pim-1) has proved to be an oncogene and it is known that to depress Pim-1 activity may be a novel oncological treatment strategy. SGI-1776, a small molecule, is the first clinically tested inhibitor of the Pim kinase family. Here, we aimed to explore the effect of SGI-1776 on salivary adenoid cystic carcinoma (SACC). Expression of Pim-1 was confirmed in SACC and control tissues by qRT-PCR. After SGI-1776 treatment, the Pim-1 expressions and Pim-1 kinase activity in both SACC-83 and SACC-LM cell lines were measured. Cell proliferation, cell invasion, cell cycle, apoptosis and mitochondrial membrane potential were analyzed. Also, the expression of FOXO3a, p-FOXO3a, RUNX3, Bcl-2, BAD, p-BAD, Bim and p-Bim were detected by Western blot. The results showed that Pim-1 was significantly overexpressed in SACC tissues. SGI-1776 down-regulated the Pim-1 expression, inhibited Pim-1 kinase activity, reduced cell proliferation, decreased invasive ability, increased caspase-3 activity and induced apoptosis, cell cycle arrest and mitochondrial depolarization. Reduced expression was also seen in p-FOXO3a, RUNX3, Bcl-2, p-BAD and p-Bim, whereas no significant changes were observed from FOXO3a, BAD and Bim. These results confirm the pivotal role of Pim-1 in SACC and suggest that targeting Pim-1 kinase signal pathway by SGI-1776 might be a promising therapeutic modality for SACC.

    Full Text Available BackgroundPulmonary mucoepidermoid carcinoma (PMEC and pulmonary adenoid cystic carcinoma (PACC are the two major types of primary salivary gland-type (PSGT lung cancers. The demographic profile, clinicopathological features, and predictors of survival as an overall group have not been described for PSGT cancers of lung.MethodsIn this study, we analyzed demographic, clinical, and survival data from 1,032 patients (546 PMEC and 486 PACC who were diagnosed of PSGT lung cancer in the Surveillance, Epidemiology and End Results database from 1973 to 2014.ResultsThe PSGT constituted 0.09% of all lung cancers with age-adjusted incidence rate of 0.07 per 100,000 person-years and change of −32% from 1973 to 2014. The incidence of PMEC was slightly higher than PACC but there were no differences in the age and sex distribution. PACCs (55% were significantly higher at trachea and main bronchus while PMECs were more common at peripheral lungs (85%. Most of the tumors were diagnosed at an early stage and were low grade irrespective of histology. As compared to PMEC, significantly higher number of patients with PACC underwent radical surgery and received adjuvant radiation. The 1- and 5-year cause-specific survival was 76.6 and 62.8%, respectively. On multivariate analysis, the survival was affected by age at diagnosis, tumor stage, histological grade, period of diagnosis, and surgical resection. The histology showed strong interaction with time and hazard ratio of patients with PACC was significantly worse than patients with PMEC only after 5 years.ConclusionThe incidence of pulmonary PSGT cancer is 7 cases per 10 million population in the United States and is decreasing. There was no difference between demographic profile of patients with PMEC and PACC but pathological features were diverse. The difference in the survival of patients with the two histological types surfaced only after 5 years when survival of patients with PMEC was better than PACC.

    In this study, we retrospectively compared the usefulness of cone beam CT (CBCT) with that of digital subtraction angiography (DSA) in the identification of the origin of the cystic artery during arterial embolization for hepatocellular carcinoma. Subjects were sixty-four patients who underwent transcatheter arterial embolization (TAE) for hepatocellular carcinoma, in whom both CBCT and DSA were performed. Two radiologists independently examined CBCT and DSA images, and attempted to identify the origin of the cystic artery in each image. For DSA, en face views were reviewed on the monitor. For CBCT, 5 mm thick horizontal sections were generated using Workstation software, and the MPR (multi-planner reconstruction) method was used for coronary sections. These were then investigated with OsiriX. Of the sixty-four patients, the cystic arterial origin could be identified using DSA in 21 (32.8%) and CBCT in 62 (96.8%). The cystic artery was shown to originate in the proper, right, middle, and left hepatic artery in one, 58, two, and one patient, respectively. These results show that CBCT was more useful than DSA for identifying cystic arterial origin. Therefore CBCT should be positively applied during TAE. (author)

  9. Nedaplatin as a Single-Agent Chemotherapy May Support Palliative Therapy for Patients with Adenoid Cystic Carcinoma: A Case Report

    Hiroyuki Hirakawa

    2017-08-01

    Full Text Available Adenoid cystic carcinoma (ACC is a rare form of adenocarcinoma, which is a broad term describing any cancer that begins in the glandular tissues. It can be found in the head and neck. We report a patient with recurrent ACC arising from the submandibular gland, treated with 100 mg/m2 nedaplatin every 4 weeks. Although our patient’s lactate dehydrogenase levels, which is produced by ACC, showed a rising trend throughout the treatment, the level decreased for approximately 2 weeks immediately after administration of nedaplatin every 4 weeks. Thus, there is a possibility that the agent may be effective. Complications such as anorexia and nausea were observed, but they were tolerated and manageable. Nedaplatin may be considered as a supportive agent during palliative therapy for patients with ACC. More clinical trials regarding nedaplatin are necessary, as this study may indicate that a medical approach works well for ACC.

    Adenoid cystic carcinoma of the salivary glands has a propensity for perineural invasion, which could favor spread along the major cranial nerves, sometimes to the skull base and through the foramina to the brain parenchyma. This study evaluated the relationship between neural spread and relapse in the skull base. During surgery, we performed multiple biopsies with extemporaneous examination of the major nerves close to the tumor to guide the surgical resection. The percentage of actuarial local control at 5 years for patients with a positive named nerve and skull base infiltration was 12.5%, compared with 90.0% in patients who were named nerve-negative and without infiltration of the skull base (P = .001). Our study shows that local control of disease for patients who are named nerve-positive with skull base infiltration is significantly more complex compared with patients who are named nerve-negative without infiltration of the skull base.

    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 5 th and 6 th 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 5 th and 6 th cranial nerve involvement. Our unique case demonstrates direct invasion of cavernous sinus and could explain the 5 th and 6 th cranial nerve involvement as histopathology revealed no perineural invasion

    2017-05-01

    Full Text Available Adenoid cystic carcinoma (ACC is an uncommon malignancy of the salivary glands that is characterized by local recurrence and distant metastasis due to its resistance to conventional therapy. Platinum-based therapies have been extensively explored as a treatment for ACC, but they show little effectiveness. Studies have shown that a specific group of tumor cells, harboring characteristics of cancer stem cells (CSCs, are involved in chemoresistance of myeloid leukemias, breast, colorectal and pancreatic carcinomas. Therapeutic strategies that target CSCs improve the survival of patients by decreasing the rates of tumor relapse, and epigenetic drugs, such as histone deacetylase inhibitors (HDACi, have shown promising results in targeting CSCs. In this study, we investigated the effect of the HDACi Suberoylanilide hydroxamic acid (Vorinostat, and cisplatin, alone or in combination, on CSCs and non-CSCs from ACC. We used CSCs as a biological marker for tumor resistance to therapy in patient-derived xenograft (PDX samples and ACC primary cells. We found that cisplatin reduced tumor viability, but enriched the population of CSCs. Systemic administration of Vorinostat reduced the number of detectable CSCs in vivo and in vitro, and a low dose of Vorinostat decreased tumor cell viability. However, the combination of Vorinostat and cisplatin was extremely effective in depleting CSCs and reducing tumor viability in all ACC primary cells by activating cellular senescence. These observations suggest that HDACi and intercalating agents act more efficiently in combination to destroy tumor cells and their stem cells.

Consideration should be given to thyroidectomy followed by total-body scanning and serum studies for foci of thyroid carcinoma and adjuvant therapy with thyroidectomy and radioablation if residual disease is identified (a. Additionally, extrapolating from data for mucinous adenocarcinomas, consideration could be given to adjuvant chemotherapy after appropriate staging (b. Strumal carcinoid tumors should be treated as tumors of low malignant potential. Observation is appropriate if after complete staging, no invasive implants are noted (c.

    The type II alveolar epithelial cell is one of two pluripotential stem cell phenotypes in normal mammalian lung morphogenesis; cells manifesting this phenotype have been found to constitute bronchioloalveolar regions of canine adenocarcinomas. We now studied type II cell expression in canine acinar adenocarcinomas and adenoid cystic (bronchial gland) carcinomas, using the same bronchogenic carcinoma model (subcutaneous bronchial autografts treated with 3-methylcholanthrene). Distinctive features of type II cells are the approximately cuboid cell shape, large and roundish nucleus, immunofluorescent staining of the cytoplasm for the surfactant protein SP-A, and presence of multilamellar bodies or their precursory forms. Cells with these type II cell characteristics were found in the basal epithelial layer of all tumor lesions and in upper layers as far as the lumen, singly or in clusters; they were also found in early invasive carcinomatous lesions but not in bronchial glands or bronchial epithelium before carcinogen exposure. Immunoblots of tumor homogenates showed reactive proteins within size classes of SP-A (28 to 36 kd) or its dimeric form (56 to 72 kd). These findings and those previously reported are consistent with the concept that chemical carcinogenesis in the adult bronchial epithelium may lead to type II cell carcinomas of varying glandular (acinar, adenoidcystic or bronchioloalveolar) growth patterns.

Materials and methods: This article screened the abstract and full-text papers that investigated salivary gland primary ACC of head and neck. Two independent reviewers searched for articles published before October 2017 in three databases (Web of Science, PubMed, and Ovid, having no limits in date and language. Statistical data were analyzed statistically by Review Manager 5.3. Results: In total, 18 studies involving 2993 patients were included in the analysis. Of the 2993 patients, 473 patients had cervical lymph node metastasis, with a merge frequency of 16% (95% CI: 13–19. Among included articles, only 4 involved cervical lymph node occult metastases, with a merge frequency of 14% (95% CI: 9–20. There were 5 articles containing minor salivary glands (MiSGs involving 370 patients of which 92 patients had cervical lymph node metastases and the merge frequency was 25% (95% CI: 11–38. Moreover, there were 4 studies on major salivary glands involving 904 patients of which 158 patients had cervical lymph node metastases and the merge frequency was 17% (95% CI: 15–20. Conclusion: Elective neck dissection is unnecessary for all patients with salivary gland ACC of head and neck. Moreover, compared with major salivary glands, MiSGs have a higher cervical lymph node metastases rate in ACC. The overall cervical lymph node metastases rate of MiSGs is 25%, which is enough to attract our attention. Therefore, we suggest that neck dissection might be

    The aim of this study was to determine the clinicopathological features and surgical outcomes of mucinous cystic neoplasm of the liver (MCN) and mucin-producing intraductal papillary neoplasm of the intrahepatic bile duct (M-IPNB). We performed a multi-institutional, retrospective study of patients with MCN or M-IPNB pathologically defined by the presence or absence of an ovarian-like stroma. The M-IPNB and MCN were diagnosed in 119 and nine patients, respectively. MCN was observed in female patients, while M-IPNB produced symptoms of cholangitis. M-IPNBs were classed as low or intermediate grade in 53 cases, high grade in 23 and invasive carcinoma in 43. Fifty-one of the M-IPNBs were the pancreatobiliary type (PT), 33 were the intestinal type (IT), 23 were the oncocytic type (OT), and 12 were the gastric type (GT). The 1-, 5- and 10-year survival rates for the 105 patients with M-IPNB were 96%, 84% and 81%, respectively, while the 5-year survival rate for patients with MCN was 100%. OT and GT M-IPNB had better 10-year survival rates than PT and IT M-IPNB. Although MCN has different features from M-IPNB, both diseases have a good prognosis after resection.

    Adenoid cystic carcinoma (ACC) is the most common malignant epithelial cancer of the lacrimal gland. Despite a slow rate of growth, ACCs are ultimately associated with poor clinical outcome. Given the rarity of this disease, most recommendations regarding therapy are guided by expert opinion and retrospective data rather than level 1 evidence. Surgery and postoperative radiation therapy are commonly used as initial local treatment. In patients at high risk of recurrence, concomitant platinum-based chemotherapy may be added to postoperative radiotherapy in an attempt to enhance radio-sensitivity. While encouraging responses have been reported with intra-arterial neoadjuvant chemotherapy, this strategy is associated with substantial toxicity and should be considered investigational. For patients with metastatic disease not amenable to surgery or radiotherapy, chemotherapy may have a role based on its modest efficacy in non-lacrimal ACC. Similarly, molecular targeted agents may have a role, although the agents tested to date in non-lacrimal ACC have been disappointing. A better understanding of the biology of ACC will be crucial to the future success of developing targeted agents for this disease.

    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.

    Thymidylate synthase (TS) is an important target for chemotherapeutic treatment of cancer and high expression of TS has been associated with poor prognosis or refractory disease in several cancers including colorectal and head and neck cancer. Although TS is known to regulate cell cycles and transcription factors, its potency as a therapeutic target has not been fully explored in adenoid cystic carcinoma (ACC). An ACC cell line (ACC3) was transfected with siRNA targeting the TS gene and inhibition of cell growth and induction of apoptosis-associated molecules were evaluated in vitro. In addition, the in vivo effect of TS siRNA on tumor progression was assessed using a xenograft model. Our results demonstrated that ACC3 cells showed significantly higher TS expression than non-cancer cell lines and the induction of TS siRNA led to inhibition of cell proliferation. The effect was associated with an increase in p53, p21, and active caspase-3 and S-phase accumulation. We also found up-regulation of spermidine/spermine N1-acetyltransferase (SSAT), a polyamine metabolic enzyme. Furthermore, treatment with TS siRNA delivered by atelocollagen showed a significant cytostatic effect through the induction of apoptosis in a xenograft model.

    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

    Adenoid cystic carcinoma (AdCC) of the head and neck is an uncommon malignant epithelial tumour of the secretory glands. Many patients develop slowly growing local recurrence and/or distant metastasis, for which treatment options are limited. A retrospective analysis of 9 AdCC patients was conducted to analyse the visualization of AdCC on PSMA PET/CT and to investigate the expression of PSMA on primary, recurrent and metastatic AdCC tumour tissue using immunohistochemistry. Local recurrence occurred in six patients and eight developed distant metastasis. All PET/CTs depicted PSMA-ligand uptake. Four PSMA PET/CTs showed suspected residual disease, eight scans depicted uptake in areas suspected of distant metastasis. Median Maximum Standardized Uptake Value (SUV{sub max}) in local recurrent and distant metastatic AdCC was 2.52 (IQR 2.41-5.95) and 4.01 (IQR 2.66-8.71), respectively. All primary tumours showed PSMA expression on immunohistochemistry (5-90% expression), as well as all available specimens of local recurrence and distant metastases. PSMA PET/CT is able to detect and visualize local recurrent and distant metastatic AdCC. PSMA-specific targeting is supported by PSMA expression on immunohistochemistry. (orig.)

    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.

    In this pictorial essay we present the typical appearances of cystic pancreatic tumours, the wide spectrum of their features, and differential features among cystic pancreatic masses with an emphasis on CT. Pseudocysts are the most common cystic lesion in the pancreas and can be induced by pancreatitis, trauma or surgery. Pseudocysts appear as a round cystic mass with a definite wall. However, they can mimic cystic tumours associated with internal septation and/or necrotic mass of various shapes. Conversely, cystic tumours can appear as a simple cyst lacking any thickening of wall, septation or mural nodule. Pancreatic carcinoma not infrequently induces secondary cysts upstream of the obstructed pancreatic duct. The cysts are pseudocysts or retention cysts in nature. When cysts are formed in the pancreatic parenchyma or adjacent to pancreatic carcinoma they may mimic cystic tumour. (orig./VHE)

    We report the treatment outcomes of 195 patients with hypopharyngeal carcinoma treated at our institute during the nine-year period between 2001 and 2009. The five-year overall survival rate and cause-specific survival rate of all patients except for M1 cases were 47.7% and 56.8%. The five-year cause-specific survival rates of patients with Stage I, II, III, IV A and IV B were 80.2%, 86.9%, 66.8%, 45.5 and 0.0%, respectively. We consider that TPLE and concurrent chemoradiotherapy (CCRT) are standard treatments. We select CCRT for patients of complete response (CR) or partial response (PR) after induction chemotherapy. The five-year cause-specific survival rate of the induction chemotherapy (ICT) good response (CCRT) group, good response (TPLE) group, poor response (CCRT) group, and poor response (TPLE) group were 68.7%, 65.6%, 53.6%, and 32.9%, respectively. Patients of the good response (CCRT) group had a good prognosis, but patients of the poor response (TPLE) group had a poor prognosis. (author)

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

    Directory of Open Access Journals (Sweden)

    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.

    Forty eight patients with adenoid cystic carcinoma(ACC) in the head and beck treated between 1979 and 1990 were reviewed according to treatment modalities and clinical courses. The common site of origin was minor salivary gland (69%), mostly had palate and maxillary sinus. 11 patients received radiation therapy(RT) alone and 37 patients received combined surgery and radiation therapy. The follow-up period of the survivors ranged from 4 to 118 months (median 49.5 months). The 5 year local control rate was 69.3%, 67.3% and 83.9% in RT alone, conservative operation(OP)+RT and radical OP+RT group, respectively(p>0.05). The control of local disease was best achieved with radical OP+RT. In postoperative RT, high dose (≥60 Gy) and generous field size (>64cm 2 ) yielded a better local control rate. Actuarial overall survival rate was 79.0%, at 5 years and 19.2% at 10 years. Distant metastases (DM) developed in 40% of patients, mostly in the lung. Disease-free(NED) survival rate was 45.8%, at 5 years and significant differences did not exist according to primary sites and treatment options. Survival rate after the onset of DM was 19.5% at 5 years. Occurrence of DM tends to lower survival significantly. In an effort to find the role of RT in the treatment of ACC, our data suggest that a well-planned postoperative RT employing a high dose and generous field size can produce high local control rate and remaining urgent problem of distant metastasis demands more effective chemotherapy for the purpose of improving survival of ACC patients

    To investigate the inhibitory effect and underlying mechanism of total saponins from Paris polyphylla var. yunnanensis on the proliferation of salivary adenoid cystic carcinoma ACC-83 cells. In vitro cell culture was performed. The proliferation of ACC-83 cells treated with different concentrations (5, 10, 20, 40, 60, 80, 100 μg·mL⁻¹) of total saponins from Paris polyphylla var. yunnanensis was observed using CCK-8 assay. Meanwhile, the apoptosis of ACC-83 cells treated with different concentrations (25, 50, 100 μg·mL⁻¹) of the total saponins was observed using flow cytometry. The expression levels of macrophage migration inhibitory factor (MIF) and CD74 were measured using Western blot and reverse transcription-polymerase chain reaction. The total saponins from Paris polyphylla var. yunnanensis induced apoptosis and expressed dose-effect relationship. ACC-83 cells expressed MIF and CD74, and the total saponins suppressed MIF and CD74 expression in ACC-83 cells. The total saponins from Paris polyphylla var. yunnanensis can significantly inhibit the proliferation, suppress MIF and CD74 expression, and promote apoptosis in ACC-83 cells. This study provides a theoretical basis for the treatment of salivary adenoid cystic carcinoma using Paris polyphylla var. yunnanensis.

Fluorescence microscopy and transmission electron microscopy were used to observe the autophagic process. Western blot was performed to detect the expression of microtube-related protein 1 light-chain 3 (LC3. An experimental adenoid cystic carcinoma (ACC lung metastasis model was established in nude mice to detect the impacts of SIL on lung weight and lung cancer nodules. Immunohistochemistry was used to detect the expressions of LC3 in human ACC samples and normal salivary gland tissue samples.Results: SIL inhibited the proliferation of ACC-M cells in a dose- and time-dependent manner, and inductively increased the autophagic bodies in ACC-M cells. Furthermore, SIL could increase the expression of LC3 in ACC-M cells and promote the conversion of LC3-I into LC3-II in a dose- and time-dependent manner. In the ACC lung metastasis model, the lung weight and left and right lung nodules in the SIL-treated group were significantly less than those in the control group (P<0.05. The expressions of LC3-I and LC3-II as well as the positive expression rate of LC3 (80% significantly increased, but the positive expression of LC3 in human ACC (42.22% reduced significantly.Conclusion: SIL could inhibit the proliferation and lung metastasis of ACC-M cells by possibly inducing tumor cells autophagy.

    To seek for the ultrasound (US) findings of partially cystic thyroid nodules that are associated with malignancy. We reviewed the US characteristics of 22 surgically confirmed partially cystic papillary carcinomas, and compared them with those of 80 benign partially cystic nodules. The review cases were selected in a random order from a total of 1029 partially cystic nodules that were diagnosed with an US-guided fine needle aspiration biopsy over a period of 8 years (June 2003 to October 2010) at our institution. In partially cystic thyroid nodules, a taller-than-wide shape (100%, p<0.001) and spiculated or microlobulated margin (58.3%, p 0.003) were significantly associated with malignancy. In terms of internal solid portion of the nodule, eccentric configuration (68.0%, p<0.001), non-smooth margin (81.3%, p<0.001), hypoechogenecity (30.0%, p<0.042), and microcalcification (89.5%, p<0.001) were more frequently demonstrated in malignant nodules than benign ones. In partially cystic thyroid nodules, understanding the characteristics of US findings is important to make a precise diagnosis of malignant nodules.

    We reviewed treatment outcomes and prognostic factors for patients with salivary ductal carcinoma (SDC) treated with surgery and postoperative radiotherapy from 2005 to 2012. A total of 16 patients were identified and 15 eligible patients were included in analysis. Median age was 61 years (range, 40 to 71 years) and 12 patients (80%) were men. Twelve patients (80%) had a tumor in the parotid gland, 9 (60%) had T3 or T4 disease, and 9 (60%) had positive nodal disease. All patients underwent surgery and postoperative radiotherapy. Postoperative radiotherapy was delivered using 3-dimensional conformal radiotherapy or intensity-modulated radiotherapy. Locoregional failure-free survival (LRFFS), distant failure-free survival (DFFS), progression-free survival (PFS), and overall survival (OS) were calculated using the Kaplan-Meier method. Differences in survival based on risk factors were tested using a log-rank test. Median total radiotherapy dose was 60 Gy (range, 52.5 to 63.6 Gy). Four patients received concurrent weekly chemotherapy with cisplatin. Among 10 patients who underwent surgery with neck dissection, 7 received modified radical neck dissection. With a median follow-up time of 38 months (range, 24 to 105 months), 4-year rates were 86% for LRFFS, 51% for DFFS, 46% for PFS, and 93% for OS. Local failure was observed in 2 patients (13%), and distant failure was observed in 7 (47%). The lung was the most common involved site of distant metastasis. Surgery and postoperative radiotherapy in SDC patients resulted in good local control, but high distant metastasis remained a major challenge.

    Purpose: To assess the role of Gamma Knife radiosurgery (GKRS) in the treatment of nonsurgical cystic brain metastasis, and to determine predictors of response to GKRS. Methods: We reviewed a prospectively maintained database of brain metastases patients treated at our institution between 2006 and 2010. All lesions with a cystic component were identified, and volumetric analysis was done to measure percentage of cystic volume on day of treatment and consecutive follow-up MRI scans. Clinical, radiologic, and dosimetry parameters were reviewed to establish the overall response of cystic metastases to GKRS as well as identify potential predictive factors of response. Results: A total of 111 lesions in 73 patients were analyzed; 57% of lesions received prior whole-brain radiation therapy (WBRT). Lung carcinoma was the primary cancer in 51% of patients, 10% breast, 10% colorectal, 4% melanoma, and 26% other. Fifty-seven percent of the patients were recursive partitioning analysis class 1, the remainder class 2. Mean target volume was 3.3 mL (range, 0.1-23 mL). Median prescription dose was 21 Gy (range, 15-24 Gy). Local control rates were 91%, 63%, and 37% at 6, 12, and 18 months, respectively. Local control was improved in lung primary and worse in patients with prior WBRT (univariate). Only lung primary predicted local control in multivariate analysis, whereas age and tumor volume did not. Lesions with a large cystic component did not show a poorer response compared with those with a small cystic component. Conclusions: This study supports the use of GKRS in the management of nonsurgical cystic metastases, despite a traditionally perceived poorer response. Our local control rates are comparable to a matched cohort of noncystic brain metastases, and therefore the presence of a large cystic component should not deter the use of GKRS. Predictors of response included tumor subtype. Prior WBRT decreased effectiveness of SRS for local control rates.

    Purpose: To assess the role of Gamma Knife radiosurgery (GKRS) in the treatment of nonsurgical cystic brain metastasis, and to determine predictors of response to GKRS. Methods: We reviewed a prospectively maintained database of brain metastases patients treated at our institution between 2006 and 2010. All lesions with a cystic component were identified, and volumetric analysis was done to measure percentage of cystic volume on day of treatment and consecutive follow-up MRI scans. Clinical, radiologic, and dosimetry parameters were reviewed to establish the overall response of cystic metastases to GKRS as well as identify potential predictive factors of response. Results: A total of 111 lesions in 73 patients were analyzed; 57% of lesions received prior whole-brain radiation therapy (WBRT). Lung carcinoma was the primary cancer in 51% of patients, 10% breast, 10% colorectal, 4% melanoma, and 26% other. Fifty-seven percent of the patients were recursive partitioning analysis class 1, the remainder class 2. Mean target volume was 3.3 mL (range, 0.1-23 mL). Median prescription dose was 21 Gy (range, 15-24 Gy). Local control rates were 91%, 63%, and 37% at 6, 12, and 18 months, respectively. Local control was improved in lung primary and worse in patients with prior WBRT (univariate). Only lung primary predicted local control in multivariate analysis, whereas age and tumor volume did not. Lesions with a large cystic component did not show a poorer response compared with those with a small cystic component. Conclusions: This study supports the use of GKRS in the management of nonsurgical cystic metastases, despite a traditionally perceived poorer response. Our local control rates are comparable to a matched cohort of noncystic brain metastases, and therefore the presence of a large cystic component should not deter the use of GKRS. Predictors of response included tumor subtype. Prior WBRT decreased effectiveness of SRS for local control rates

    In children medulloblastoma is a commonly encountered posterior fossa midline tumour in which cystic degeneration is not uncommon. A cystic medulloblastoma without solid component has, however, not been described. We report a 12-year-old boy with a posterior fossa midline cystic lesion on CT with surgical and histological confirmation of the diagnosis. (orig.)

    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

    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.

    Full Text Available A 61-year-old female patient with adenoid cystic carcinoma (ACC of the right maxilla and Angle class II division 1 malocclusion had received a subtotal maxillectomy in right side and used a conventional clasp-retained obturator. After implants placement, a maxillary interim immediate obturator (IIO and then a definitive obturator using six endosseous implants were fabricated. During one-year follow-up, the patient was completely satisfied. Ideally, after implants placement in edentulous patients suffering from hemimaxillectomy, an implant-supported obturator (ISO is designed in order to prevent nasal reflux and to improve speech and swallowing. However, in the following case, because of skeletal class II division 1 malocclusion and implants insertion in the premaxilla, using an ISO was impossible because it would cause excessive upper lip protrusion and lack of anterior teeth contact. Therefore, a five-unit implant-supported fixed partial denture (FPD was fabricated in the maxillary anterior segment so that anterior teeth contacts were possible and the patient’s normal lip support was achieved. A bar and three ball attachments were used in the maxillary posterior segment. A closed-hollow-bulb ISO was preferred. Conventional ISO in these patients results in several problems. Using a maxillary anterior FPD along with ISO caused satisfactory results in the current patient.

    Full Text Available Salivary adenoid cystic carcinoma (ACC is a rare relentlessly progressive malignant tumor. The molecular events associated with ACC tumorigenesis are poorly understood. Variable microRNAs (miRNA have been correlated with tumorigenesis of several solid tumors but not in ACC. To investigate the association of miRNAs with the development and/or progression of ACC, we performed a comparative analysis of primary ACC specimens and matched normal samples and a pooled salivary gland standard and correlated the results with clinicopathologic factors and validated selected miRNAs in a separate set of 30 tumors.MiRNA array platform was used for the identification of target miRNAs and the data was subjected to informatics and statistical interrelations. The results were also collected with the MYB-NFIB fusion status and the clinicopathologic features.Differentially dysregulated miRNAs in ACC were characterized in comparison to normal expression. No significant differences in miRNA expression were found between the MYB-NFIB fusion positive and -negative ACCs. Of the highly dysregulated miRNA in ACC, overexpression of the miR-17 and miR-20a were significantly associated with poor outcome in the screening and validation sets.Our study indicates that the upregulation of miR-17-92 may play a role in the biology of ACC and could be potentially targeted in future therapeutic studies.

  10. Genetic profiling reveals cross-contamination and misidentification of 6 adenoid cystic carcinoma cell lines: ACC2, ACC3, ACCM, ACCNS, ACCS and CAC2.

    Full Text Available Adenoid cystic carcinoma (ACC is the second most common malignant neoplasm of the salivary glands. Most patients survive more than 5 years after surgery and postoperative radiation therapy. The 10 year survival rate, however, drops to 40%, due to locoregional recurrences and distant metastases. Improving long-term survival in ACC requires the development of more effective systemic therapies based on a better understanding of the biologic behavior of ACC. Much preclinical research in this field involves the use of cultured cells and, to date, several ACC cell lines have been established. Authentication of these cell lines, however, has not been reported. We performed DNA fingerprint analysis on six ACC cell lines using short tandem repeat (STR examinations and found that all six cell lines had been contaminated with other cells. ACC2, ACC3, and ACCM were determined to be cervical cancer cells (HeLa cells, whereas the ACCS cell line was composed of T24 urinary bladder cancer cells. ACCNS and CAC2 cells were contaminated with cells derived from non-human mammalian species: the cells labeled ACCNS were mouse cells and the CAC2 cells were rat cells. These observations suggest that future studies using ACC cell lines should include cell line authentication to avoid the use of contaminated or non-human cells.

    Merkel cell carcinoma (MCC) is a rare cutaneous malignancy occurring mostly in older immunocompromised Caucasian males. A growing incidence of MCC has been reported in epidemiological studies. Treatment of MCC usually consists of surgical excision, pathological lymph node evaluation, and adjuvant radiotherapy. This paper reports the experience of a single tertiary center institution with 17 head and neck Merkel cell carcinoma patients. Median followup for the cohort was 37.5 months. After five years, recurrence-free survival, disease specific survival, and overall survival were 85%, 90%, and 83%, respectively. Our limited data support the use of adjuvant radiotherapy. We also report two cases of MCC located at the vestibule of the nose and two cases of spontaneous regression after diagnostic biopsy. About 40% of our patients were referred to our center for surgical revision and pathological lymph node evaluation. Increased awareness of MCC and an interdisciplinary approach are essential in the management of MCC.

None of the investigated structures was in itself an ideal marker......Controversy centres on the role and identification of myoepithelial (MEC) and basal cells in salivary gland tumours, and recent studies suggest that both basal cells and myoepithelial cells participate in the formation of salivary gland tumours.

    The aim of this study was to evaluate the disease outcomes of patients treated with definitive and adjuvant radiotherapy for squamous cell carcinomas of the nasal cavity and paranasal sinuses in a single institution. Between 2007–2012 patients were retrospectively identified from electronic databases who had undergone surgery and adjuvant radiotherapy or definitive radiotherapy for sinonasal squamous cell carcinomas with curative intent. Fourty three patients with sinonasal squamous cell carcinoma were identified (22 nasal cavity, 21 paranasal sinuses). 31/43 (72 %) had T3 or T4 disease; nodal stage was N0 in 38, N1 in 4, Na/b in 0 and N2c in 1 patient. Median age was 67 years (range 41–86). 18 (42 %) received definitive and 25 (58 %) adjuvant radiotherapy. Radiotherapy was delivered using either conventional radiotherapy (n = 39) or intensity modulated radiotherapy (n = 4). Elective neck radiotherapy was delivered to two patients. Chemotherapy was delivered to 6/43 (14 %) of patients. Two-year local control, regional control, distant metastases free survival, progression free survival, cause specific survival and overall survival were 81 %, 90 %, 95 %, 71 %, 84 % and 80 % respectively. There was no significant difference in outcome comparing patients who underwent surgery and adjuvant radiotherapy with patients receiving definitive radiotherapy (2 year locoregional disease free survival 75 % and 70 % respectively, p = 0.98). Pooly differentiated tumours were significantly associated with inferior disease outcomes. Local, regional, combined local and regional, and distant failure occurred in 7 (16 %), 3 (7 %), 1 (2 %) and 2 (5 %) of patients; all 3 regional recurrences were in patients with nasal cavity squamous cell carcinomas who had not undergone elective neck treatment. Definitive or adjuvant radiotherapy provides an effective treatment for sinonasal malignancies. The main pattern of failure remains local, suggesting the need for investigation of

    Purpose: To report on our experience in the treatment of nasopharyngeal carcinoma (NPC) by radical radiotherapy alone in our institution during the last decade. Methods and Materials: From January 1990 to May 1999, 905 NPC patients were treated and were studied retrospectively. Radical radiotherapy was given to this cohort by conventional technique in a routine dose of 70-72 Gy to the primary tumor and metastatic lymph nodes. In case of residual primary lesion, a boost dose of 8-24 Gy was delivered by either 192 Ir afterloading brachytherapy, fractionated stereotactic radiotherapy, conformal radiotherapy, or small external-beam fields. Results: The 5-year and 10-year local-regional control, overall survival, and disease-free survival rates were 81.7% and 76.7%, 76.1% and 66.5%, 58.4% and 52.1%, respectively. In case of residual primary lesions after a dose of 70-72 Gy of conventional external-beam radiotherapy (EBRT), an additional boost was able to achieve a local control of 80.8%, similar to that obtained with primary lesions that completely disappeared at 70-72 Gy (82.6%, p = 0.892). Conclusions: The treatment results of radical EBRT followed by a boost dose to the residual primary tumor for nasopharyngeal carcinoma in our institution are promising

    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.

    To assess the epidemiological and clinico-pathological features, surgical and reconstructive techniques, adjuvant treatments and clinical outcome of breast carcinoma in males (BCM) at the Egyptian National Cancer Institute (NCI). Patients and methods: Thirty-two males with breast carcinoma presented to NCI between January 2000 and December 2002. They were evaluated by complete history, physical examination, laboratory and radiological investigations. Results: Median age was 59 years. Left sided and retroareolar breast lumps were the commonest presentations. Grade 11 tumors positive for hormone receptors were very common. Stage I, II, 111 and IV disease were encountered in 6.2%, 34.4%, 34.4% and 25.0% of patients, respectively. Curative surgery was done in 22 patients; they received adjuvant hormonal therapy, chemotherapy and radiotherapy in 22,16 and 10 patients, respectively. Eight metastatic patients were treated with palliative measures. Surgery was done in 25 patients; the most common procedure was modified radical mastectomy (40.6%). Primary closure was feasible in 17 patients (68%), local flaps were needed in 4 cases (16%), while myocutaneous flap was done in 3 cases (12%). The commonest complication was development of seroma (9 cases). The overall survival (OS) at 5 years was 65.4%. The disease free survival (DPS) at 5 years was 53.9%. Stage and curative surgery significantly affected OS, while type of surgery was the only variable significantly affecting DPS. Conclusion: Male breast carcinoma occurs at older ages than females, usually in advanced stage. This necessitates directing attention of males and awareness on the prevalence and risk factors for this disease.needed in 4 cases (16%), while myocutaneous flap was done in 3 cases (12%).

    To evaluate the clinical features, treatment results, prognostic factors and late toxicities of nasopharyngeal carcinoma in children and adolescents. Between January 1990 and January 2011, 158 NPC patients younger than 20 years old were treated in our institution, and the patient’s clinical characteristics, treatment modalities, outcomes and prognostic factors were retrospectively analyzed. There were 9 (5.7%) patients in stage II, 60 (38.0%) in stage III and 89 (56.3%) in stage IV according to the UICC2002 staging system. Neck mass (32.3%), headache (21.5%) and nasal obstruction (15.2%) were the most common chief complaints. With a median follow-up time of 62.5 months (range 2.0-225.0 months), the 5-year overall survival (OS) rate, local-regional control (LRC) rate and distant metastasis-free survival (DMFS) rate were 82.6%, 94.9% and 76.4%, respectively. There were 43 (27.2%) patients failed during the follow up, with seven local-regional recurrences and 38 distant metastases. In univariate analysis, the 5-year OS of T4 and T1-3 were 75% and 87.9%, p = 0.01, stage IV and stage II-III were 77.1% and 90%, p = 0.04, respectively. In multivariate analysis, T4 (p = 0.02) and stage IV (p = 0.04) were the independent adverse prognostic factors for OS. Significant reduction in trismus (27.3% v 3.6%, p = 0.03) and G2 xerostomia (37.9% v 10.3%, p = 0.02) was observed in patients treated by IMRT. Most childhood and adolescence nasopharyngeal carcinoma patients were locally advanced diseases at first diagnosed. The treatment results of radiotherapy, with or without chemotherapy, are excellent in our institution. Reducing distant metastasis with new strategies and late toxicities with intensity-modulated radiotherapy are the future directions for the treatment of adolescent nasopharyngeal carcinoma

    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

    Background: Treatment of local relapse in adenoid cystic carcinoma (ACC) following prior radiation remains a challenge: without the possibility of surgical salvage patients face the choice between palliative chemotherapy and re-irradiation. Chemotherapy yields response rates around 30% and application of tumouricidal doses is difficult due to proximity of critical structures. Carbon ion therapy (C12) is a promising method to minimize side-effects and maximize re-treatment dose in this indication. We describe our initial results for re-irradiation in heavily pre-treated ACC patients. Methods: Patients treated with carbon ion therapy between 04/2010 and 05/2013 (N = 52 pts, median age: 54 a) were retrospectively evaluated regarding toxicity (NCI CTC v.4), tumour response (RECIST) and control rates. 48 pts (92.3%) received carbon ions only, 4 pts received IMRT plus C12. Results: 4 pts were treated following R1-resection, 43 pts for inoperable local relapse. Most common tumour sites were paranasal sinus (36.5%), parotid (19.2%), and base of skull (17.3%). Pts received a median dose of 51 GyE C12/63 Gy BED and cumulative dose of 128 Gy BED [67–182 Gy] after a median RT-interval of 61 months. Median target volume was 93 ml [9–618 ml]. No higher-grade (>°II) acute reactions were observed, 7 pts showed blood–brain-barrier changes (°I/II: 8 pts; °III: 2 pts), 1 pt corneal ulceration, xerophthalmia 7 pts, °IV bleeding 1 pt, tissue necrosis 2 pts, otherwise no significant late reactions. Objective response rate (CR/PR) was 56.6%. With a median follow-up of 14 months [1–39 months] local control and distant control at 1a are 70.3% and 72.6% respectively. Of the 18 pts with local relapse, 13 pts have recurred in-field, 1 pt at the field edge, 3 pts out of field, and one in the dose gradient. Conclusion: Despite high applied doses, C12 re-irradiation shows moderate side-effects, response rates even in these heavily pre-treated patients are encouraging and present a

This study aimed to evaluate the therapeutic outcome of NPC with CN palsy and to analyze the prognostic factors.Patients and methods: A total of 104 NPC patients with CN palsy curatively treated by conventional (n=44 or conformal (n=60 radiotherapy (RT were enrolled. Upper CN palsy was present in 81 patients, lower CN palsy in four patients, and both upper and lower CN palsy in 19 patients. Forty-one patients had CN palsy for >2 months before diagnosis.Results: Complete recovery of CN palsy was observed in 74 patients. The actuarial 5-year locoregional control (LRC, distant metastasis-free survival (DMFS, and overall survival (OS rates were 58.2%, 62.2%, and 38.4%, respectively. No significant difference was observed in CN recovery, LRC, DMFS, or OS for patients treated by conventional versus conformal technique. However, significant reduction of grade 3 or greater toxicities was found in those treated by the conformal technique (odds ratio =0.28.Conclusion: Patients with CN palsy presenting >2 months before diagnosis were hard to recover from palsy. The LRC, OS, and recovery from CN palsy did not significantly change with the treatment evolution. Patients with complete recovery from CN palsy had longer OS.

    We used data management software to compare pathology report data concerning regional lymph node sampling for colorectal carcinoma from 2 institutions using different dissection methods. Data were retrieved from 2 disparate anatomic pathology information systems for all cases of colorectal carcinoma in 2003 involving the ascending and descending colon. Initial sorting of the data included overall lymph node recovery to assess differences between the dissection methods at the 2 institutions. Additional segregation of the data was used to challenge the application's capability of accurately addressing the complexity of the process. This software approach can be used to evaluate data from disparate computer systems, and we demonstrate how an automated function can enable institutions to compare internal pathologic assessment processes and the results of those comparisons. The use of this process has future implications for pathology quality assurance in other areas.

    CT and US were carried out on 81 patients with hepatocellular carcinoma, 20 patients with cholangiocellular carcinoma and 94 patients with metastatic liver cancer. 1) Cystic degeneration was observed in one with hepatocellular carcinoma (1.2%), one with cholangiocellular carcinoma (5.0%) and 12 with metastatic liver cancer (12.8%) by US, but this change was observed in only 5 by CT (1,0,4, respectively). Metastatic liver cancer showed the highest incidence among these tumors. 2) The characteristics of cystic degeneration of the liver tumors were thickened wall and irregularity of the inner surface of the wall. 3) Judging from macroscopic and histopathological findings, liquefactive necrosis in the tumors was shown as ''echoluent'' area. We concluded that cystic degeneration was one of the important findings in metastatic liver cancer and that careful observation by US and CT avoided the confusion with other hepatic cystic diseases.

    Purpose: To analyze the outcomes of patients with early hypopharyngeal cancer treated with radical radiotherapy (RT). Methods and Materials: Ten institutions combined the data from 115 patients with Stage I-II hypopharyngeal squamous cell carcinoma treated with definitive RT between 1990 and 2001. The median patient age was 67 years; 99 patients were men and 16 were women. Of the 115 patients, 39 had Stage I and 76 had Stage II disease. Conventional fractionation was used in 98 patients and twice-daily RT in 17 patients; chemotherapy was combined with RT in 57 patients. The median follow-up period was 47 months. Results: The overall and disease-specific 5-year survival rate for 95 patients without synchronous malignancies was 66.0% and 77.4%, respectively. The 5-year disease-specific survival rate by T stage was 95.8% for patients with T1 disease and 70.1% for patients with T2 disease (p = 0.02). Of the 115 patients, local control with laryngeal voice preservation was achieved in 34 of 39 patients with T1 lesions, including 7 patients successfully salvaged, and in 56 of 76 patients with T2 lesions. Sixty-five patients (56.5%) had synchronous or metachronous cancers. Of the 115 patients, 19 died of hypopharyngeal cancer, 10 died of second primary cancers, and 14 died of other causes during the study and follow-up periods. Conclusions: Patients with early hypopharyngeal cancer tended to have a good prognosis after RT. However, second malignancies had an adverse effect on the overall outcomes of patients with early hypopharyngeal cancer

    Cystic fibrosis is an autosomal recessive genetic disease. Among Caucasians, it is the most common cause of pulmonary insufficiency during the first three decades of life. The prevalence of cystic fibrosis varies according to ethnic origin: it is common among Caucasians but rare among Asians. We report a case in which cystic fibrosis with bronchiectasis and hyperaeration was revealed by high-resolution CT, and mutation of the cystic fibrosis conductance transmembrane regulator gene (CFTR) by DNA analysis

    To report the results of combined chemoradiation (CCRT) with cisplatin versus carboplatin in locally advanced cervical carcinoma. From 2009 to 2013, 255 patients with stage IIB-IVA cervical carcinoma, according to FIGO staging were prospectively assigned to be treated with pelvic radiotherapy followed by brachytherapy given concurrently with cisplatin or carboplatin in the treatment of locally advanced cervical cancer. Treatment outcomes and toxicitiy were evaluated. Two-hundred and thirteen patients could be evaluated. At a median follow-up time of 43 months (6–69 months), the 3-year local control, disease-free survival, metastasis-free survival and overall survival rates were 93, 80.8, 85.0 and 87.3 %, respectively. No statistical difference in terms of local control, disease-free survival, metastasis-free survival and overall survival rates between cisplatin and carboplatin treatments was observed in this study. Eighty-six percents of the patients in the carboplatin group could receive more than 4 cycles, while there were only 72 % in the cisplatin group who completed more than 4 cycles (p = 0. 02). In terms of acute toxicity, cisplatin caused significantly more anemia (p = 0.026), neutropenia (p = 0. 044) and nephrotoxicity (p = 0. 031) than carboplatin. No difference in late toxicity was observed in this study. Carboplatin yielded comparable results to cisplatin in concurrent chemo-radiation for locally advanced cervical cancer. In addition, carboplatin was associated with a better compliance rate and was associated with less of anemia, neutropenia and nephrotoxicity

    A phase II study of chemoradiotherapy for advanced squamous cell carcinoma of the thoracic esophagus was carried out cooperatively by nine Japanese institutions. Forty-five patients with thoracic advanced squamous cell carcinoma, who had T4 tumor or distant lymph node metastasis (M1{sub (LYM)}), were enrolled in the study for treatment with cisplatin (70 mg/m{sup 2}) on days 1 and 36, and 5-fluorouracil infusion (700 mg/m{sup 2}) on days 1-4 and 36-39 sandwiched around external beam irradiation (60 Gy over 6 weeks). Of the 45 evaluable patients, 37 (84.1%) completed the treatment. The overall response rate was 64.4%, and the complete response rate 8.9%. The median duration of response was 125.0 days for patients who achieved complete and partial response. The 50% median survival time was 215 days. There was one toxicity-related death due to radiation pneumonitis. The major form of toxicity exceeding grade 2 was myelosuppression and anorexia, but grade 4 toxicity was also observed (2 pulmonary, 1 severe hypoxemia, 1 severe cardiac failure and 1 mental disturbance). The results showed that this form of chemoradiotherapy had a satisfactory effect and might be useful for treatment of inoperable advanced esophageal cancer. (author)

    Multiple primaries in a single patient are uncommon, though not very rare. The existence of such cancers in two un-related, non-paired organs is even more un-common. Here, we present a case of 55 years old male who presented to us with a mucoepidermoid carcinoma of the parotid gland and was operated. Later on, he presented with a large cystic swelling in the pelvis which turned out to be pseudomyxoma peritonei. A review of slides and immunohistochemistry indicated it to be adenocarcinoma colon. He presented again with recurrent mucoepidermoid carcinoma of the parotid which was operated successfully with the use of myocutaneous flap for wound closure. He is currently undergoing chemotherapy. In order to establish a separate mono-clonal etiology of both tumours, immunohistochemistry was performed. To the best of our knowledge, carcinoma multiplex in the colon and the parotid has never been reported before. (author)

    The incidence of invasive cancer within a mucinous cystic neoplasm of the pancreas varies between 6 and 36%. Polycystic ovarian syndrome is a disorder characterized by hyperandrogenism and anovulatory infertility. One surgical treatment that can restore endocrine balance and ovulation in polycystic ovarian syndrome is partial ovarian destruction. Successful pregnancies following preconception pancreaticoduodenectomies (Whipple procedures) and chemoradiation to treat pancreatic neoplasms have been reported rarely but none were diagnosed with pre-cancer polycystic ovarian syndrome-associated infertility. Gemcitabine is an antimetabolite drug used for the treatment of pancreatic cancer that can have profound detrimental effects on oogenesis and ovarian function. Whether the ovarian destructive property of gemcitabine could act as a method to restore ovulation potential in polycystic ovarian syndrome is unknown. A 40-year-old white American woman with a history of pancreatic cancer treatment with a Whipple procedure and chemoradiation with gemcitabine had a successful pregnancy after years of pre-cancerous anovulatory infertility and polycystic ovarian syndrome. She received no fertility agents and delivered full term via a spontaneous vaginal delivery with no pregnancy complications. Gemcitabine treatment for pancreatic cancer may result in resumption of ovulation in women with polycystic ovarian syndrome and these women should be counseled accordingly.

    Mucinous tubular and spindle cell carcinoma (MTSCC) of the kidney is a recently identified renal malignancy. Diagnosis of this rare subtype of renal tumour can be challenging for pathologists, and as such, any additional data would be helpful to improve diagnostic reliability. As imaging features of this new and rare sub-type have not yet been clearly described, the purpose of this study was to describe the main radiologic features on computed tomography (CT) and magnetic resonance imaging (MRI), based jointly on the literature and findings from a multi-institutional retrospective review of pathology and imaging databases. Using a combination of CT/MRI features, diagnosis of MTSCC could be suggested in many cases. A combination of slow enhancement with plateau on dynamic contrast-enhanced CT/MRI, intermediate to high T2 signal intensity contrasting with low apparent diffusion coefficient values on MRI appeared evocative of this diagnosis.

    Mucoepidermoid carcinoma is the most common salivary gland tumor with varying behavior among different histopathological grades. The objective of this study was to determine the expression of Bcl-2 protein in mucoepidermoid carcinoma (MEC) and to correlate with histological grades. The records of 40 cases of MEC were collected from the histopathology department. Fresh slides were prepared and fresh diagnoses were made using the grading criteria for MEC. Immunohistochemical markers for Bcl-2 were applied and the results analyzed using the chi-square test. Of 40 cases, 20 were males and 20 were females. The range in age of the patients was 6 to 67 years mean (SD) was 42.6 (1.85) years. Twenty-two were low grade (55%), 11 high grade (27.5%) and 7 (17.5%) were intermediate grade MEC. Among these 40 cases, Bcl-2 expression was positive in 24 cases and negative in 16 cases. In 22 cases of low-grade MEC, 19 were positive while only 3 were negative. In high-grade tumors, all 11 cases were found to have a negative expression of Bcl-2 protein. In intermediate-grade MEC, 5 cases showed positive expression while only 2 cases showed negative expression. Bcl-2 protein expression showed positive expression in low-grade and negative expression in high-grade MEC. Intermediate grade showed more than 50% positive results for Bcl-2. Correlation between grades of MEC and expression of Bcl-2 is statistically significant and can be used for the depicting the prognosis of MEC along with other prognostic and clinico-pathological parameters.

    Nasopharyngeal Carcinoma (NPC) is a common malignant neoplasm of the head and neck that occurs most commonly in people in the South Eastern Asia but its condition in Iran is not much clear. In this retrospective study, we evaluated the treatment characteristics determining the outcome in patients with NPC. In this retrospective study, we reviewed the records of one hundred and seven patients with biopsy proven diagnosis of NPC who were referred to the radiation oncology department, Nemazee Hospital, Shiraz University of Medical Sciences, Iran, during the time period from January 1985 to December 2000. Eightyfive patients (79.4%) received 60-70Gy radiation (1.8- 2Gy/fraction, one fraction per day, and 5 fractions per week). Sixty-two patients (57.5%) received radiotherapy combined with adjuvant chemotherapy which consisted of cisplatin and 5-fluorouracil. Eighty-six patients (80.4%) had WHO II-III histopathologic diagnosis. According to the AJCC 1997 staging system, 4 (3.6%), 3 (2.7%), 33 (30.8%) and 67 (62%) patients were in stages I, II, III and IV, respectively. With a median follow-up of 12 months, the 2-year overall and disease-free survival rates were 35% and 21%, respectively. According to the multivariate analysis for overall survival, patients under 40 years had a better prognosis (p=0.041). Node stage and stage of disease were significant prognostic factors (p=0.0001). On multivariate analysis for disease-free survival, age and node stage were significant prognostic factors. The patients who received more than 60Gy radiation had a better prognosis (p=0.02), however; sequential adjuvant chemotherapy had no impact on survival and response (p=0.6). Our experience confirmed earlier reports showing poor outcomes for locoregionally advanced nasopharyngeal carcinomas. This study failed to demonstrate improvement in the outcome regarding overall and disease-free survival by adding sequential adjuvant chemotherapy after radiotherapy for patients with advanced NPC.

    Renal cell carcinoma (RCC) is more common in renal transplant and dialysis patients than the general population. However, RCC in transplanted kidneys is rare, and treatment has previously consisted of nephrectomy with a return to dialysis. There has been recent interest in nephron-sparing procedures as a treatment option for RCC in allograft kidneys in an effort to retain allograft function. Four patients with RCC in allograft kidneys were treated with nephrectomy, partial nephrectomy, or radiofrequency ablation. All of the patients are without evidence of recurrence of RCC after treatment. We found nephron-sparing procedures to be reasonable initial options in managing incidental RCCs diagnosed in functioning allografts to maintain an improved quality of life and avoid immediate dialysis compared with radical nephrectomy of a functioning allograft. However, in non-functioning renal allografts, radical nephrectomy may allow for a higher chance of cure without the loss of transplant function. Consequently, radical nephrectomy should be utilized whenever the allograft is non-functioning and the patient's surgical risk is not prohibitive. © 2013 John Wiley & Sons A/S.

    Full Text Available Objective: The purpose of the study was to identify trends in incidence rates of oral squamous cell carcinoma (OSCC at specific anatomic sites or within specific age or sex groups in the Western Uttar Pradesh population. Materials and Methods: The study covers the period from January 2004 through April 2009. OSCC cases were retrospectively analysed for site, age, gender and habits and the findings were formulated to chart the trends in Western U.P. Results: The study revealed a male to female ratio of 2.2:1 with the largest number of OSCCs developing in the fourth and fifth decades of life. Overall, the most common site was the buccal mucosa (63.75%, followed by retromolar area (15%, floor of the mouth (11.25%, lateral border of the tongue (3.75%, labial mucosa (3.75%, and palate (2.5%. Smokeless tobacco habit was more prevalent than smoking tobacco in both men as well as women. Karl - Pearson′s correlation coefficient was calculated to find the degree of association between the two variables i.e. between gender to buccal mucosa and gender to smokeless and smoking tobacco habits, which were found to be positively correlated with respect to the age. Conclusion: Oral cancer is an important cause of morbidity and mortality worldwide with an incidence rate that varies widely by geographic location. Even within one geographic location, the incidence varies among groups categorized by age, sex, site or habit.

    To evaluate the efficacy and safety of ureteroscopic thulium laser (TL) treatment of upper urinary tract carcinoma (UTUC). Forty-two consecutive patients underwent conservative TL treatment for UTUC at two referral institutions. All patients underwent preliminary biopsy and then laser vaporization. A 272 μm and 365 μm laser fibers were used with a flexible and semirigid scope, respectively. Ablation was carried out with a 10 to 20 W power. Mean age at surgery was 68 years (SD 10.7). Mean tumor size was 14.3 mm (range 2-30 mm). Preliminary biopsy revealed the presence of low-grade disease in 29 (69.1%) patients, high-grade disease in 4 (9.5%) and 1 carcinoma in situ 1 (2.4%), whereas it was not conclusive in 8 (19%) cases. Final stage was pTa and pTis in 41 (97.6%) and 1 (2.4%) patients, respectively. Thirty eight percent (16) experienced Clavien-Dindo grade I complication, 47.6% (20) grade II, and 2.4% (1) grade III. Five (12%) patients underwent a second-look procedure due to residual disease. Eight (19%) patients experienced clinical recurrence. The median estimated recurrence-free survival was 44 months (SE 3.68). Four patients (9.5%) underwent a nephroureterectomy. Final pathological stage was pTis, pT3 high grade, pTa low grade, and pT0. Median follow-up was 26.3 months (range 2-54 months), and no progression or upstaging of disease occurred. TL management of UTUC is a safe and efficacious conservative treatment. Our experience shows optimal vaporization and hemostatic control in the absence of major complications.

    Extrapulmonary small-cell carcinoma (EPSCC) is clinically underrecognized and optimal management remains illusive. Although head and neck EPSCC tends to involve early widespread dissemination and poor prognosis, recently reported favorable outcomes have used concurrent chemoradiotherapy in limited-stage disease. We report an EPSCC case of arising in the hypopharynx successfully treated by induction chemotherapy followed by concurrent chemoradiotherapy. To clarify EPSCC clinically, we retrospectively reviewed clinical courses of all EPSCC records between 1999 and 2008 in a single-institution series. The 14 subjects identified had primary sites at the gastrointestinal tract in 5, uterine cervix in 3, genitourinary system in 2 and at the gallbladder, liver, hypopharynx, and an unidentified primary lymph node in one case each. Of the 14, 2 cases had stage I, 2 cases had stage II, 4 cases had stage III, 5 cases had stage IV in tumor-node-metastasis (TNM) classification. Stage IV subjects usually underwent platinum-based chemotherapy, to which 25% showed partial response (PR) and 75% progressive disease (PD) with median overall survival (OS) of 114.0 days, or 16 weeks. Of stage III or lower subjects, 75% underwent surgery and 62.5% chemotherapy. OS was 1244.0 days or 3.7 years and 2-year survival rates was estimated at 87.5%. Survival duration differed significantly between those in stage III or lower and those in group IV. Age significantly affected survival time in the Cox proportional hazard regression model. Brain metastasis was uncommon in this series, despite the absence of prophylactic cranial radiation. Further studies are needed to improve and clarify the clinical EPSCC course. (author)

    Previously, no therapeutic agent has been known to improve the overall survival compared with placebo in patients with hepatocellular carcinoma (HCC), who have progressed after sorafenib. In this patient population, regorafenib was first demonstrated to confer a survival benefit in the RESORCE trial, and subsequently it was approved as a second-line treatment for patients with advanced HCC. An open-label expanded access program (EAP) of regorafenib was implemented for compassionate use. We investigated the efficacy and safety of regorafenib based on our experience of the RESORCE trial and the EAP. Data from 5 patients from the RESORCE trial and 6 from the EAP were analyzed retrospectively. All patients had tolerated prior sorafenib and were progressing during sorafenib treatment. The median progression-free survival was 9.2 months (95% CI 2.3-16.1). One patient achieved a partial response and 7 achieved stable disease. The objective response rate was 9.1%, and the disease control rate was 72.7%. No treatment-associated mortalities were observed. Grade 3 hypophosphatemia was observed in 2 patients, grade 2 anorexia was observed in 5 patients, and grade 3 neutropenia was observed in 2 patients. Grade 2 and grade 3 thrombocytopenia were observed in 2 and 3 patients, respectively. All treatment-related adverse events were improved by reduction or interruption of regorafenib. Five patients showed decreased serum albumin levels. Sorafenib and regorafenib sequential therapy presents a safe and effective treatment option for patients with advanced HCC. © 2017 S.

    Background To report location and management of atypical metastases from renal cell carcinoma (RCC) in the Instituto Nacional de Ciencias Medicas e Investigacion Salvador Zubiran (INCMNSZ) in Mexico City. Methods Between 1987 to 2009, 545 patients with RCC were retrospectively identified at the INCMNSZ. Patients with unusual metastases confirmed by histopathology were analyzed. Epidemiological, clinical, diagnosis, treatment and outcome data were reviewed. Results Sixty patients developed 98 unusual metastases secondary to RCC. The group was comprised of 35 men (58.3%), with a median age of 60 years at diagnosis. Metachronous unusual metastases with primary renal cancer were observed in 37 individuals (61.7%). Median time from primary RCC diagnosis to the first unusual metastasis was 16.5 months. Median survival from diagnosis of the first unusual metastasis to death was 5.0 months (CI 95%: 2.8-7.2 months). Patients with an initial solitary metastatic lesion in an unusual site (28.3%) had a better survival compared to patients who primarily presented with multiple metastases, 17.0 (CI 95%: 6.1-27.9) Vs 3.0 months (CI 95%: 0.9-5.1), p = 0.001. Unusual metastasis resection (21 patients) improved survival, 25.0 (CI 95%: 5.1-44.9) Vs 3.0 months (CI 95%: 0.8-5.2), p < 0.0001. No survival difference was observed between localization of unsual metastases (p = 0.72). Conclusions In patients with advanced RCC we suggest an individual diagnostic and surgical approach to achieve complete resection with disease-free margins, even in the presence of unusual metastatic sites, multifocality, or history of metastasectomy. These strategy might provide not only palliation for symptoms, but an opportunity for meaningful disease free and overall survival. PMID:29147198

    We reviewed the treatment outcomes and prognostic factors for patients with anal canal carcinoma who were treated with curative intent chemoradiotherapy (CRT) at Severance Hospital from 2005 to 2011. Data for 38 eligible patients treated during this period were reviewed. All patients were treated with curative intent using radiotherapy (RT) with (n = 35) or without concomitant chemotherapy (n = 3). Among 35 patients who received CRT, most of the chemotherapeutic regimens were either 5-fluorouracil (5-FU) plus mitomycin C (23 patients) or 5-FU plus cisplatin (10 patients). Recurrence-free survival (RFS), colostomy-free survival (CFS), overall survival (OS), and locoregional control (LRC) rates were calculated using the Kaplan-Meier method and survival between subgroups were compared using the log-rank test. Cox's proportional hazard model was used for multivariate analysis. Over a median follow-up period of 44 months (range, 11 to 96 months), 3-year RF S, Cfs, OS, and LRC were 80%, 79%, 85%, and 92%, respectively. In multivariate analysis, tumor size >4 cm was an independent predicting factor for poorer RFS (hazard ratio [HR], 6.35; 95% confidence interval [CI], 1.42 to 28.5; p = 0.006) and CFS (HR, 6.25; 95% CI, 1.39-28.0; p = 0.017), while the presence of external iliac lymph node metastasis was an independent prognosticator for poorer OS (HR, 9.32; 95% CI, 1.24 to 70.3; p 0.030). No treatment-related colostomies or deaths occurred during or after treatment. Curative intent CRT resulted in excellent outcomes that were comparable to outcomes in previous randomized trials. No severe treatment-related toxicities were observed.

    Full Text Available Although the adrenal glands are not common sites of metastasis from hepatocellular carcinoma (HCC, this metastasis can be met in patients with advanced HCC in some clinical settings. However, the effectiveness of radiotherapy against such metastases is unclear. Therefore, we performed the present multi-institutional study to investigate tumor response, overall survival (OS, treatment-related toxicity, and prognostic factors after radiotherapy. We retrospectively reviewed 134 patients who completed a planned radiotherapy for their adrenal metastases. Complete response was noted in 6 (4.3%, partial response in 48 (34.0%, and stable disease in 78 patients (55.3%. The median OS was 12.8 months, and the 1-, 2-, and 5-year OS rates were 53.1%, 23.9%, and 9.3%, respectively. Grade 3 anorexia occurred in 2 patients, grade 3 diarrhea in 1, and grade 3 fatigue in 1. Multivariate analyses revealed that the following factors had significant effects on OS: controlled intrahepatic tumor; controlled extrahepatic metastasis; and Child-Pugh class A. Although patients with adrenal metastasis from HCC had poor OS, radiotherapy provided an objective response rate of 38.3% and disease stability of 93.6%, with minimal adverse events. Therefore, radiotherapy for these patients could represent a good treatment modality, especially for patients with controlled intrahepatic tumors, controlled extrahepatic metastasis, and good hepatic function.

    To examine the influence of smoking history on the diagnosis and other tumor characteristics of upper tract urothelial carcinoma in Japan. A total of 1509 patients with upper tract urothelial carcinoma who were diagnosed in 2005 from 348 Japanese institutions were registered using the multi-institutional national database of the Japanese Urological Association and included in this analysis. Clinical data of the patients were collected in 2011. The associations between the patients' self-reported smoking history and their age at the diagnosis of upper tract urothelial carcinoma, sex, pathological T stage and tumor grade were analyzed. The mean age at the diagnosis of upper tract urothelial carcinoma was approximately 5 years earlier for the 238 current smokers than for the 618 current non-smokers (P smokers, the age at diagnosis for the smoking ≥ 20 cigarettes per day group was 6.5 years lower than that of the perspective of both healthcare and medical economies. © 2015 The Japanese Urological Association.

    The incidence of ductal carcinoma in situ (DCIS) has increased markedly in recent decades. In the past, mastectomy was the primary treatment for patients with DCIS, but as with invasive cancer, breast-conserving surgery followed by radiation therapy (RT) has become the standard approach. We present the final results of a multi-institutional retrospective study of an Italian Radiation Oncology Group for the study of conservative treatment of DCIS, characterized by a very long period of accrual, from February 1985 to March 2000, and a median follow-up longer than 11 years. A collaborative multi-institutional study was conducted in Italy in 10 Radiation Oncology Departments. A consecutive series of 586 women with DCIS histologically confirmed, treated between February 1985 and March 2000, was retrospectively evaluated. Median age at diagnosis was 55 years (range: 29–84); 32 patients were 40 years old or younger. All women underwent conservative surgery followed by whole breast RT. Irradiation was delivered to the entire breast, for a median total dose of 50 Gy; the tumour bed was boosted in 295 cases (50%) at a median dose of 10 Gy. After a median follow-up of 136 months (range: 16–292 months), 59/586 patients (10%) experienced a local recurrence: invasive in 37 cases, intraductal in 20 and not specified in two. Salvage mastectomy was the treatment of choice in 46 recurrent patients; conservative surgery in 10 and it was unknown in three patients. The incidence of local recurrence was significantly higher in women younger than 40 years (31.3%) (p= 0.0009). Five patients developed distant metastases. Furthermore 40 patients developed a contralateral breast cancer and 31 a second primary tumour in a different site. The 10-year actuarial overall survival (OS) was 95.5% and the 10-year actuarial disease-specific survival (DSS) was 99%. Our results are consistent with those reported in the literature. In particular it has been defined the importance of young age (40

    Stage IIIC endometrial carcinoma (EC) represents pathologically heterogenous patients with single/multiple pelvic (stage IIIC1) or paraaortic (stage IIIC2) lymph nodes (LNs). There is an increasing trend to offer adjuvant chemotherapy (CT) +/- radiation (RT) uniformly to these patients, regardless of substage. We investigate the prognostic significance of positive LN (pLN) number, ratio (%pLN), location (IIC1 vs. IIC2), and adjuvant treatment on patterns of failure and survival in a large collaborative multi-institutional series. Clinical data for stage III EC patients such as patient characteristics, surgery/pathologic details, adjuvant therapies (including CT, RT, and chemotherapy and radiation), and outcomes (including pelvic control [PC], disease-free survival [DFS], distant DFS, and overall survival [OS]) were collected from 3 academic institutions. Log-rank analyses, Cox regression univariate and multivariate analyses were performed. Of the 264 patients queried for stage III disease, 237 (73%) had pLN, and complete LN sampling for analysis. The mean number of pLN in the combined data were 3.9, with 26.1% of all LN sampled positive; 121 patients (51%) staged IIIC1, and 116 patients (49%) staged IIIC2. There was a significant difference in number of pLN (P=0.0006) and total LN sampled by institution (range, 13 to 35; P=0.0004), without a difference in %pLN (P=0.35). Ninety-seven of 220 (44.1%) have ≥20% pLN. While controlling for substage and institution, a decrease in DFS (hazard ratio [HR], 1.1; P=0.007), and OS (HR, 1.1; P=0.01) was observed with every increase of 10% in the pLN ratio. There was a significant difference in DFS (HR, 1.8; P=0.003), PC (HR, 1.9; P=0.004), and distant DFS (HR, 1.6; P=0.03), as well as a trend for decreased OS (HR, 1.6; P=0.08) for substage IIIC2 versus IIIC1 disease; 5 years DFS 40% versus 45%, OS 50% versus 57%. Patients received no adjuvant therapy (10%), CT alone (27%), RT alone (16%), or chemotherapy and radiation (47

    Lobular neoplasia (LN) represents a spectrum of atypical proliferative lesions, including atypical lobular hyperplasia and lobular carcinoma-in-situ. The need for excision for LN found on core biopsy (CB) is controversial. We conducted a prospective multi-institutional trial (TBCRC 20) to determine the rate of upgrade to cancer after excision for pure LN on CB. Patients with a CB diagnosis of pure LN were prospectively identified and consented to excision. Cases with discordant imaging and those with additional lesions requiring excision were excluded. Upgrade rates to cancer were quantified on the basis of local and central pathology review. Confidence intervals and sample size were based on exact binomial calculations. A total of 77 of 79 registered patients underwent excision (median age 51 years, range 27-82 years). Two cases (3%; 95% confidence interval 0.3-9) were upgraded to cancer (one tubular carcinoma, one ductal carcinoma-in-situ) at excision per local pathology. Central pathology review of 76 cases confirmed pure LN in the CB in all but two cases. In one case, the tubular carcinoma identified at excision was also found in the CB specimen, and in the other, LN was not identified, yielding an upgrade rate of one case (1%; 95% CI 0.01-7) by central pathology review. In this prospective study of 77 patients with pure LN on CB, the upgrade rate was 3% by local pathology and 1% by central pathology review, demonstrating that routine excision is not indicated for patients with pure LN on CB and concordant imaging findings.

    Full Text Available Cystic nephroma is a rare, benign multicystic lesion of the kidney. This tumor occurs both in children and in adults. In children, it is highly prevalent in males; in adults, it is more frequent in women. The term “cystic nephroma” represents two apparently different entities: pediatric cystic nephroma, a benign form thought to originate from metanephric tissue, and adult cystic nephroma, considered as a lesion of mixed epithelial stromal tumor. The clinical presentation may be a palpable mass or nonspecific symptoms such as abdominal pain, hematuria, and urinary tract infections. In this review, we summarize the ultrasound imaging features of cystic nephroma and describe the characteristics of the most common renal cystic lesions and the differential diagnosis of cystic nephroma with other renal cystic lesions.

    Teratomas are rare germline tumors that originate from one or more embryonic germ cell layers. Teratoma of the kidney is extremely rare, and less than 30 cases of primary intrarenal teratomas have been published to date. We report the main radiologic features of an unusual case of mature cystic teratoma arising from the left kidney in a two-year-old boy. A left-sided abdominal mass was detected on physical examination and B-Mod Ultrasound (US) examination revealed a heterogeneous mass with central cystic component. Computed tomography (CT) demonstrated a lobulated, heterogeneous, hypodense mass extending craniocaudally from the splenic hilum to the level of the left iliac fossa. Nephrectomy was performed and a large, fatty mass arising from the left kidney was excised. The final pathologic diagnosis was confirmed as cystic renal teratoma

    We herein describe a case of cystic lymphangioma in the greater omentum of the remnant stomach, which is thought it to be related with subtotal gastrectomy 10 yr ago for early gastric cancer. A 76-yr-old man was admitted to our department with postprandial abdominal discomfort and bowel habit change. Intraabdominal multilocular cystic mass was detected by ultrasonography and computed tomography. We performed a complete En-bloc tumor resection including spleen and distal pancreas, and histological examination confirmed cystic lymphangioma originated from the greater omentum of the remnant stomach. Although the etiology of omental lymphangioma remains largely unclear, these findings suggested strongly that obstruction of the lymphatic vessels after gastric resection for gastric carcinoma might be the most plausible cause. The surgical extirpation with resection of organs involved appears to be a treatment of choice for such unusual case.

    To determine the rate of subsequent primary site failure in patients with head and neck squamous cell carcinoma of unknown primary (UKP HNSCC) in a region with a high prevalence of cutaneous squamous cell carcinoma, according to a pre-determined institutional policy. Secondary aims included regional and distant control, and overall survival. Patients presenting between April 2005 and June 2016 to the Princess Alexandra Hospital Head and Neck Multidisciplinary Meeting with UKP HNSCC from either presumed mucosal or cutaneous sites treated with curative intent were eligible. Patients with presumed mucosal origin were treated with radiation therapy (RT) with or without chemotherapy, while patients with presumed cutaneous SCC were treated with surgery and post-operative RT with or without chemotherapy. A total of 63 patients met the inclusion criteria. Median follow up duration was 3.9 years (IQR 2.07-5.14). There were no subsequent primary site failures. The rate of nodal failure among presumed mucosal patients was 11.5%, and 8.1% among presumed cutaneous patients. The rate of distant metastatic failure was 11.1% among all patients. The estimated 5 year overall survival was 71.2% (95% CI 59.2-85.7%). Treatment according to our pre-defined institutional policy for UKP HNSCC in a region with a high prevalence of cutaneous SCC appears to be safe and effective with low rates of mucosal primary emergence and nodal failure.

    Full Text Available Abstract Background The pathogenesis of salivary gland carcinomas is very complex and prognostic markers are difficult to find in these carcinomas of which the different subtypes have varying malignant potential. The study was conducted to examine the cellular distribution of maspin and MCM2 in salivary gland carcinomas and their value to predict lymph node metastasis. Materials and methods Fifty three paraffin blocks of different lesions (15 muco-epidermoid carcinoma, 14 adenoid cystic carcinoma, 3 epi-myoepithelial carcinoma, 5 salivary duct carcinoma, 5 malignant pleomorphic adenoma, 6 polymorphous low grade adenocarcinoma and 5 acinic cell carcinoma were prepared for immunohistochemical staining with maspin and MCM2 antibodies. ANOVA and Pearson correlation tests were used for the statistical analysis of the results. Results All salivary gland carcinomas express maspin and MCM2 with variable cellular localization. There was a significant difference in the expression of each antibody between mucoepidermoid carcinoma, adenoid cystic carcinoma and polymorphous low grade adenocarcinoma. No association was found between examined markers and lymph node metastasis. Conclusions Salivary gland carcinomas express maspin and MCM2 with variable levels and cellular localization, consisting important markers of biological behavior in these tumors. The level of MCM2 expression can be used in the differential diagnosis of adenoid cystic carcinoma and polymorphous low grade adenocarcinoma. Further study with large sample size is recommended to assess their value in prediction of lymph node metastasis.

    The prevalence and etiology of the cystic components within gallbladder carcinomas as seen on MR images were evaluated. A retrospective review of MR images was performed for 35 proven gallbladder carcinomas in search of radiologically detectable intratumoral cystic components. The pathologic specimens were meticulously reviewed to determine the etiology. MR images of 31 adenomyomatoses were also reviewed for comparison to clarify the difference in MR features between these two entities. Three cases out of 35 proven gallbladder carcinomas were found to have intratumoral cystic components. They were all well-differentiated adenocarcinomas, and the cystic components consisted of dilated neoplastic glands filled with abundant mucin pool. Adenomyomatosis tended to have more and rounded cystic components (Rokitansky-Aschoff sinuses) lined in a linear fashion and were flat-elevated in shape, smaller in size and had a regular surface, as compared to the three carcinomas. Although rare, radiologists need to be aware that well-differentiated gallbladder carcinoma with mucin production can have cystic components, which may mimic adenomyomatosis. Careful interpretation of MR images may provide useful information in the differentiation of these two entities. (orig.)

Methods: Between Jan 1990 and Dec 2009, totally 148 pathological confirmed nasopharyngeal carcinoma (NPC) patients with age ≤20 years were treated in our hospital, including stage II 8, stage III 58, stage IV 81, and unknown 1 when restaged by TNM system (UICC 2002), ninety-four (63.5%) patients were treated with radiotherapy alone, 54 (36.5%)patients were treated with radiotherapy combined with cisplatin-based chemotherapy. Results: The median follow-up time for all patients was 44.5 months. The 5-year overall survival (OS), local-regional control (LRC) and distant metastasis-free survival (DMFS) rates were 82.9%, 85.1% and 78.6%. There were 42 patients (28.4%) failed with 16 regional recurrence and 29 distant metastasis, and 3 with both; bone metastasis was the most common site of distant metastasis(22/29). In univariate analysis,the adverse prognostic factors for OS were stage T 4 (χ 2 =5.61, P=0.018), radiation dose 2 =5.30, P=0.021), for LRC was radiation dose 2 =4.24, P=0.039). In multivariate analysis, radiation dose 4 were the independent prognostic factors for OS (χ 2 =5.73, 5.56, P=0.017, 0.018), for LRC was radiation dose 2 =5.81, P=0.016). Conclusions: The outcome of the present series was excellent, total nasopharyngeal radiation dose less than 70 Gy is inappropriate. Reduce the distant metastasis and late toxicities were the future direction for the treatment of adolescent nasopharyngeal carcinoma. (authors)

    The goal of this study was to determine the risk of malignancy of thyroid nodules with minimal cystic changes. A total of consecutive 1,000 thyroid nodules (≥1 cm) with final diagnoses from two institutions were included in this study. The risk of malignancy of thyroid nodules was analyzed according to the internal content, which was categorized as purely solid, minimally cystic (cystic changes ≤10%), and partially cystic (cystic changes >10%). We also assessed the risk of malignancy of nodules with minimal cystic changes depending on echogenicity and presence of any suspicious ultrasonografic (US) features. The overall frequency of purely solid, minimally cystic, and partially cystic nodules was 730/1,000 (73%), 61/1,000 (6.1%), and 209/1,000 (20.9%), respectively, with risks of malignancy of 14.8% (108/730), 3.3% (2/61), and 3.3% (7/209), respectively. The risk of malignancy of nodules with minimal cystic changes was significantly lower than that of purely solid nodules (P=0.013). The risk of malignancy of nodules with minimal cystic changes was also lower than that of purely solid nodules in the group of hypoechoic nodules (P=0.063) and in the group of nodules with suspicious US features (P=0.028), but was not significantly different from that of partially cystic nodules regardless of echogenicity or the presence of suspicious US features (P≥0.652). Thyroid nodules with minimal cystic changes have a low risk of malignancy, similar to that of partially cystic nodules regardless of echogenicity or the presence of suspicious US features. The US lexicon could define solid nodules as nodules with purely solid internal content in order to enhance the accuracy of estimated risks of malignancy

    Purpose: The aim of the study concerning congenital cystic lung malformations was to evaluate prenatal diagnoses postnatally to determine prognostic factors as well as to define optimized perinatal management. Materials and Methods: The study is based on 45 prenatal ultrasound examinations depicting fetal cystic lung lesions. 32 of the mothers had follow-up examinations. 5 pregnancies were terminated due to CCAM and additional malformations. Complete regression of the lesions was seen prenatally in 8 cases and postnatally in 5 children. Results: Surgical intervention due to respiratory insufficiency was necessary in 4 neonates. According to the imaging results, CCAM was present in 4 cases and sequestration in 7 patients. No correlation between the imaging findings and the surgical results was found in 3 children: One child suffered from rhadomyoid dysplasia, and in the case of the second child, a left-sided hernia of the diaphragm and additional sequestration were detected. The third child showed AV malformation. The cystic lesions of the 14 children operated upon were proven histologically. The degree of accuracy in the present study was high. Conclusion: Precise perinatal management is warranted in order to determine according to the clinical relevance surgical intervention and to prevent complications after the first year of life. This is performed during the neonatal period for respiratory insufficient neonates and within the first year of life for clinically stable children. (orig.)

    Early glottic carcinomas (T1 and T2) constitute only 2% of all laryngeal cancers in our data. Seventy patients were seen between 1985 and 1992. All patients were treated by cobalt-60 small field radiotherapy using a beam directed shell. The total dose delivered was 60-65Gy in 31 patients and 66-70Gy in 39 patients. The follow-up period ranged from 5 to 126 months, with a mean follow up of 37 months overall and 55 months in the surgical salvage group. Radiation therapy controlled disease in 71% (50 of 70) of patients overall; 75% with T1 and 67% with T2 lesions. Total laryngectomy as salvage surgery was performed in 70% (14 of 20) of patients whose disease recurred. Ultimate control including surgical salvage occurred in 64 (91 %) of 70 patients in the present study. The actuarial 5 year survival was 83 and 80% in T1 and T2 tumours, respectively (statistically insignificant). This report supports the policy of definitive irradiation, reserving surgical salvage for radiation failures in early laryngeal cancers. 17 refs., 2 tabs

    The purpose of this study was to retrospectively evaluate the volume doubling time (VDT) and growth rate of renal cell carcinomas (RCC) on a serial computed tomography (CT) scan. Thirty pathologically proven RCCs were reviewed with helical CT. Each tumor underwent at least two CT scans. Tumor volume was determined using an area measuring tool and the summation-of-areas technique. Growth rate was evaluated in terms of diameter and volume changes. VDT and volume growth rate were compared in relation to several factors (initial diameter, initial volume, diameter growth rate, volume growth rate, tumor grade, tumor subtype, sex or age). Mean VDT of RCCs was 505 days. Mean diameter and volume growth rate were 0.59 cm/year and 19.1 cm 3 /year, respectively. For volume and diameter growth rate, tumors ≤4 cm showed lower rates than those >4 cm (P 0.05). Volume growth rate was moderately to strongly positively correlated with initial diameter, initial volume and diameter growth rate (P < 0.05). In conclusion, small RCCs grew at a slow rate both diametrically and volumetrically. More accurate assessment of tumor growth rate and VDT may be helpful to understand the natural history of RCC.

    From January 1967 through November 1991, a total of 135 patients with carcinoma of the major salivary glands (parotid: 95; submandibular: 39, sublingual: 1) were treated at our department. 40 patients had adenocarcinoma, 29 adenoid cystic carcinoma, 24 mucoepidermoid carcinoma and 16 squamous cell carcinoma. 100 patients were irradiated postoperatively and the remaining 35 were treated with radiation alone. Total radiation doses delivered were 50 Gy for the postoperative group and 50 to 66 Gy for the group receiving only radiation using a [sup 60]Co single portal with or without wedged paired or single electron portal boost. Actuarial five-year survivals after radiation therapy were 55% for the postoperative group and 26% for radiation only group (p=0.0004). The local control rates for the postoperative group were 83% for adenocarcinoma, 81% for adenoid cystic carcinoma, 83% for mucoepidermoid carcinoma and 62% for squamous cell carcinoma. Corresponding figures for the radiation only group were 40% for adenocarcinoma, 38% for adenoid cystic carcinoma and 33% for mucoepidermoid carcinoma. Conventional irradiation techniques continue to play an important role because they offer superior local control for postoperative patients with carcinoma of the major salivary glands. However, the local control rates for the radiation only group were only 30 to 40%, so that new irradiation modalities such as provided by a high LET machine are needed for these patients. (orig.)

    The use of complementary/alternative medicine (CAM) has recently received considerable attention throughout the world. We evaluated the prevalence and predictors of CAM use among Japanese patients with localized prostate cancer. A total of 177 patients with localized prostate carcinoma underwent radical retropubic prostatecotomy or external beam radiation therapy between January 1994 and January 2001. Of them, 138 (78%) answered a self-administered questionnaire on CAM use and were eligible for this study. The overall prevalence, types of CAM used, and costs of CAM were assessed. The effects of age, prostate-specific antigen (PSA) level, clinical stage, pretreatment Gleason score, patients' income, patients' final educational status, and general health-related quality of life at baseline and 1 year after treatment, as estimated using the European Organization for Research and Treatment of Cancer Prostate Cancer Quality of Life Questionnaire on the prevalence of CAM use, were evaluated. Twenty-seven patients (20%) had once used or had been using some types of CAM. Herbal medicine and vitamins were the most common types of CAM used. Preoperative Gleason score was significantly associated with CAM use, as determined by the {chi}''2 test (P0.0198), and PSA level and posttreatment physical function domain were marginally associated with CAM use, as determined by the Mann-Whitney U-test (P=0.0734 and P=0.0597, respectively). Patient age, income, and final educational status had no impact on CAM use. A relatively small proportion of Japanese patients with localized prostate cancer have tried CAM compared with the proportions of patients described in previous reports from Western countries.

    Cystic fibrosis (CF) is the most frequent metabolic disorder with autosomal recessive inheritance in the Caucasian population. The gene defect is located on the long arm of chromosome 7. In Germany today, the actual median survival is 37 years. The genetic defect caused by chloride anion disturbances affects multiple body systems but the morbidity and mortality is due to lung disease. The secretion of highly viscous mucus promotes viral and bacterial pulmonary infections leading to airway obstruction and consecutive destruction of the lung parenchyma. This article will review and discuss both the clinical aspects of the disease and the diagnostic methods, referring in particular to new imaging strategies. (orig.)

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two

    2008-01-01

    Cystic lesions of the pancreas encompass a broad spectrum of benign, premalignant, and malignant tumors which are primarily cystic or result from cystic necroses of solid neoplasms. Because of the wide use of cross-sectional imaging techniques they are increasingly being identified in asymptomatic patients as well as in patients presenting with abdominal pain, jaundice or pancreatitis. Among these lesions, intraductal papillary mucinous neoplasms, serous cystic neoplasms and mucinous cystic neoplasms represent the majority of cases. With increasing experience with these tumors, a refinement of our understanding of their morphology and of their natural course has emerged. It is important to be familiar with the CT and MR imaging features of these lesions to differentiate these tumors and to orient the diagnosis towards benign or malignant forms. Because characterization of cystic tumors of the pancreas can sometimes be difficult due to overlapping imaging features, additional criteria such as clinical symptoms, localization, age and gender have to be taken into account. If appropriately treated, these tumors can usually be cured by resection and the decreasing risk of pancreatic surgery has led to an increasing number of resections of pancreatic tumors. The management of cystic tumors of the pancreas has not yet been standardized and the correct evaluation and subsequent management of the disease in asymptomatic patients have not been fully defined.

    To describe CT findings and differential points of cystic thymic lesions. We evaluated retrospectively total 19 masses with well marginated cystic lesions at thymic area on CT scans. They were 10 teratomas, 3 congenital thymic cysts, 2 multilocular thymic cysts(associated with thymoma and myasthenia gravis in each), 2 cysts Assciated with thymic Hodgkin's lymphomas an ectopic parathyroid cyst, and an infected thymic cyst. The radiological abnormalities evaluated were thickness of the wall, presence or abscene of septa, mural nodule, solid component, calcification and fat component. All three cases of congenital thymic cysts and an ectopic parathyroid cyst appeared as thin-walled unilocular cyst with homogeneous internal density and without identifiable solid component. In multilocular thymic cyst, there were thick wall and solid components(n =2), thick internal septa and calcifications(n = 1). The cysts of teratomas manifested thick walls(n = 9), internal septa(n = 4), calcifications(n = 6), fat components(n = 4), and solid components(n = 4). Cysts in Hodgkin's diseases appeared as multilocular or unilocular and had thick wall and septa without calcification. Infected thymic cyst presented with multilocular cystic mass with identifiable wall and septa, calcification, and solid components. The thymic diseases with cystic lesion include teratomas, congenital thymic cysts, multilocular thymic cysts, parathyroid cyst, and Hodgkin's disease. Congenital thymic cyst and ectopic parathyroid cyst are thin-walled unilocular cystic lesions. Cystic lesions associated with teratoma, Hodgkin's disease, and multilocular thymic cyst are thick-walled cystic lesions with or without solid component

    Purpose: To study the CT appearances of thyroid carcinoma and its cervical metastatic lymphadenopathy, as well as to evaluate the diagnostic criteria of tumor invasion of adjacent structures. Methods: CT findings of surgery and pathology proved thyroid carcinoma in 52 patients were analyzed. Results: All of the primary tumor were heterogeneous in density, 32 tumors (82.5%) were ill-defined. Fine granular calcifications were revealed in 11 primary tumors and metastatic lymph nodes in 5 cases. Cystic formation with intracystic high density papillary-like nodules were found in 4 primary tumors and metastatic lymphadenopathy in 5 cases. Trachea, esophagus and carotic artery invasion were proved by surgery in 22, 21 and 10 cases respectively. Serrated inner wall and tumor nodule protrusion into tracheal lumen were the definite signs of trachea invasion. Use tumor encasement over 1/2 of the circumference of esophagus and 1/3 of the circumference of carotid artery as the diagnostic criterion of invasion, sensitivity was 71.4%, 100.0% specificity was 96.3%, 95.2% respectively. Conclusion: Fine granular calcification and cystic formation with high attenuation intracystic papillary-like nodules were characteristic manifestations of primary thyroid carcinoma (especially papillary carcinoma) and its metastatic lymphadenopathy as well. Contrast enhanced CT scan is helpful in the diagnosis of thyroid carcinoma and the delineation of tumor extent, which is very important in surgical planning

More than half of salivary gland carcinomas are located in the parotid gland with adenoid cystic carcinoma being the most frequent...

  3. Gastrointestinal Manifestations of Cystic Fibrosis

    Science.gov (United States)

    2016-01-01

    Cystic fibrosis has historically been considered a pulmonary disease, but with the increasing life expectancy of these patients, gastrointestinal manifestations are becoming more important. Furthermore, nutritional status is closely linked to pulmonary function and, thus, overall mortality. This article discusses gastrointestinal manifestations (which involve nutritional, pancreatic, hepatobiliary, and, in particular, gastrointestinal tract issues) of cystic fibrosis as well as management of the disease. In addition, the article discusses studies that have been critical to our understanding of gastrointestinal manifestations of cystic fibrosis. PMID:27330503

    We aimed to evaluate the effect of sarcopenia, a condition of low muscle mass, on the survival among patients who were undergoing radical nephroureterectomy (RNU) for urothelial carcinoma of the upper urinary tract (UCUT). We retrospectively reviewed consecutive patients with UCUT (cT[any]N0M0) who underwent RNU between 2003 and 2013 at our department and its affiliated institutions. Preoperative computed tomography images were used to calculate each patient's skeletal muscle index, an indicator of whole-body muscle mass. Sarcopenia was defined according to the sex-specific consensus definitions, based on the patient's skeletal muscle and body mass indexes. We analyzed the relapse-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) after RNU to identify factors that predicted patient survival. A total of 137 patients were included, and 90 patients (65.7 %) were diagnosed with sarcopenia. Compared to the non-sarcopenic patients, the sarcopenic patients had a significant inferior 5-year RFS (48.8 vs. 79.6 %, p = 0.0002), CSS (57.1 vs. 92.6 %, p sarcopenia was an independent predictor of shorter RFS, CSS, and OS (all, p Sarcopenia was an independent predictor of survival among patients with UCUT who were undergoing RNU.

    Purpose: Given the paucity of data on racial disparities in ductal carcinoma in situ (DCIS), the data from a multi-institutional cohort of DCIS patients treated with breast-conserving surgery and whole breast radiation therapy (RT) were analyzed to determine whether racial disparities or differences exist. Methods and Materials: A total of 533 white and 76 black DCIS patients from 3 university-based cancer centers were uniformly treated with breast-conserving surgery and RT. All patient data were collected and analyzed as a function of race. Results: The median follow-up was 5.2 years. No significant racial differences were seen in tumor size, age at diagnosis, estrogen receptor status, necrosis, or grade (all P>.05). Of the treatment parameters, the RT dose delivered, boost, positive margin rates, frequency of hormone receptor status assessment, and receipt of hormonal therapy for the 2 cohorts did not significantly differ (all P>.05). The local relapse-free survival was similar at 5 years (96.1% and 98.1%, P=.399) and 10 years (92.8% vs 95.8%, P=.360), with no significant overall survival difference at 10 years (94.0% vs 88.9%, P=.290) between the white and black patients, respectively. On multivariate analysis, race was not an independent predictor of local relapse-free survival or overall survival when accounting for age, grade, and margin status. Conclusion: In our large cohort of DCIS patients uniformly treated at 3 institutions with breast conservation without any apparent differences in treatment delivery parameters, we demonstrated that the clinical and pathologic features and local survival outcomes did not differ as a function of race. Our results suggest that when black patients with DCIS are appropriately selected for breast conservation and receive adjuvant RT without racial disparities in the treatment parameters, differences in the outcomes as a function of race do not exist.

    Full Text Available Background/introductionEarly reports of stereotactic body radiation therapy (SBRT for pancreatic ductal adenocarcinoma (PDAC used single fraction, but eventually shifted to multifraction regimens. We conducted a single institution review of our patients treated with single- or multifraction SBRT to determine whether any outcome differences existed.Methods and materialsPatients treated with SBRT in any setting for PDAC at our facility were included, from 2004 to 2014. Overall survival (OS, local control (LC, regional control (RC, distant metastasis (DM, and late grade 3 or greater radiation toxicities from the time of SBRT were calculated using Kaplan–Meier estimation to either the date of last follow-up/death or local/regional/distant failure.ResultsWe identified 289 patients (291 lesions with pathologically confirmed PDAC.

    With the advent of gray scale ultrasonographic equipment, the parenchymal disease of liver is more easily evaluated. Ultrasonography is a non-invasive technique, different from angiography, and performed without discomfort to patient. And also ultrasonography can be used in assessing the liver in cases showing equivocal scintigraphy and in differentiation of solid and cystic masses, first detected on scintigrams. Therefore, the complementary use of ultrasonography, Tc-99m-sulfur colloid scan and angiography provides better diagnostic accuracy for the detection of hepatocellular carcinoma, and moreover, sequential ultrasonographic studies in the same patient are valuable of following the course of hepatocellular carcinoma and monitoring the effectiveness of therapy for hepatocellular carcinoma. In thirty patients with histologically proven hepatocellular carcinoma, an analysis of ultrasound manifestation is made and the results are as follows; 1. Ultrasound manifestation of hepatocellular carcinoma by gray scale showed four different sonographic patterns including discrete echo free, discrete echogenic, ill defined echogenic and mixed patterns. 2. The size of hepatocellular carcinoma by ultrasonographic measurement was larger than 5 cm in diameter in 28 cases. 3. In 7 cases performed with angiography, all echogenicities of hepatocellualr carcinoma were correlated with the findings of vascularity of angiography. 4. In cases combined with liver cirrhosis, the sonographic pattern of hepatocellular carcinoma appeared to be discrete or ill defined echogenic patterns.

    Three cases of giant cystic craniopharyngiomas with large areas of extension beyond the suprasellar area are presented. The magnetic resonance (MR) appearance in one case is described. These giant tumors had large, multilobulated cysts that comprised the bulk of the tumors. In one case, there was an unusual extension of the large tumor cyst into the lateral ventricle. In two cases, the tumors extended to the level of the foramen magnum. On CT, the cyst contents of these two tumors were hyperdense and became hypodense postoperatively. All three tumors harbored calcifications in the form of clumps in the suprasellar region and rim calcifications around the cysts. None of the tumors exhibited contrast enhancement. A literature review of the radiographic features of craniopharyngiomas is discussed. (orig.)

    Full Text Available It was generally believed that Cystic fibrosis (CF is rare among Arabs; however, the few studies available from Egypt and other Arabic countries suggested the presence of many undiagnosed patients. The aim of the present study was to determine the frequency of CF patients out of the referred cases in a single referral hospital in Egypt. A total of 100 patients clinically suspected of having CF were recruited from the CF clinic of the Allergy and Pulmonology Unit, Children’s Hospital, Cairo University, Egypt, throughout a 2 year period. Sweat chloride testing was done for all patients using the Wescor macroduct system for collection of sweat. Quantitative analysis for chloride was then done by the thiocyanate colorimetric method. Patients positive for sweat chloride (⩾60 mmol/L were tested for the ΔF508 mutation using primer specific PCR for cystic fibrosis transmembrane conductance regulator (CFTR gene. Thirty-six patients (36% had a positive sweat chloride test. The main clinical presentations in patients were chronic cough in 32 (88.9%, failure to thrive in 27 (75%, steatorrhea in 24 (66.7%, and hepatobiliary involvement in 5 (13.9%. Positive consanguinity was reported in 50% of CF patients. Thirty-two patients were screened for ΔF508 mutation. Positive ΔF508 mutation was detected in 22 (68.8% patients, 8 (25% were homozygous, 14 (43.8% were heterozygous, and 10 (31.3% tested were negative. CF was diagnosed in more than third of patients suspected of having the disease on clinical grounds. This high frequency of CF among referred patients indicates that a high index of suspicion and an increasing availability of diagnostic tests lead to the identification of a higher number of affected individuals.

    The association of juvenile papillomatosis with carcinoma is proven, but very rare, as there exist several reported cases. A 15-year-old girl with no family history of breast cancer presented with two masses in the left breast. The excisional biopsy on both lumps revealed juvenile fibroadenoma and juvenile papillomatosis epithelial proliferation multiple cystic expanded channels. In some of these channels, cytological features of intraductal carcinoma were observed. We performed a full immunohistochemical examination of the juvenile papillomatosis. The patient refused any further surgical or adjuvant treatment. There are no signs of recurrence in the 15 year follow-up. This case is a diagnostic and therapeutic challenge, taking into account the patient's age and the controversial treatment recommendations. Good collaboration between surgeons and pathologists is essential for an accurate diagnostic process and aims to avoid under- or overtreatment.

    Objective: To evaluate the contribution of single shot fast spin echo (SSFSE) in the diagnosis of cystic lesions in the pancreas, and their relation to Wirsung's duct. Material and methods: In 66 patients (33 women and 33 men; mean age: 66 years) cystic pancreatic lesions were retrospectively analyzed. The SSFSE technique was used, including an evaluation of Wirsung's duct. Conventional pancreatic sequences were added. The following lesion features were assessed: location, number, size, relation to Wirsung's duct, nature of the cystic image and signal intensity of the neoplasm or tumor-like condition. Surgical and anatomopathological correlation was obtained in 31/66 cases (47%). Results: The cystic lesions were divided in 2 groups: A) cystic lesions related to Wirsung's duct, 30 patients: all lesions measured less than 30 mm in size. Seven patients underwent surgical treatment; in 22 cases surgery was not indicated. One patient refused surgery. A mucinous papilliferous intraductal tumor was diagnosed in 3 cases, ampullar carcinoma in 1 case, pancreatic carcinoma, 1 case, autoimmune pancreatitis, 1 case, and cystic duct dilatation due to benign fibrous stenosis, 1 case. B) Cystic lesions not related to Wirsung's duct (36 patients): 7 serous cystadenomas, 7 adenocarcinomas with a cystic component, 1 mucinous cystadenoma, 1 duodenal diverticulum, 7 pseudocysts and 1 neuroendocrine tumor. In 12 patients surgery was not carried out due to clinical contraindication or patient's refusal. Conclusion: SSFSE allowed a clear differentiation between cystic lesions related (Group A) and non-related (Group B) to Wirsung's duct. The diagnosis could not be achieved by usual MRI sequences. However, benign and malignant lesions were observed in both groups. In all cases SSFSE afforded useful data either for surgical treatment or clinical follow-up. (author)

    Curative treatment for base-of-tongue squamous cell carcinoma (BOT SCC) has evolved over time; however, comparative outcomes analysis for various treatment strategies is lacking. The authors reviewed the evolution of treatment modality and radiotherapy (RT) technique for 231 consecutive BOT SCC patients at our institution between 1981 and 2011. Treatment modalities included definitive chemoradiotherapy (chemoRT) (42%), definitive RT (33%), surgery followed by RT (20%), and surgery alone (5%). RT techniques included external beam plus interstitial brachytherapy (EBRT + IB) (37%), conventional EBRT (29%), intensity-modulated radiation therapy ± simultaneous integrated boost (IMRT ± SIB) (34%). Clinical characteristics and outcomes were stratified by modality or RT technique. Treatment modality evolved from definitive RT (1980s–1990s) to definitive chemoRT (1990s–2000s). RT technique evolved from EBRT + IB (1980s–1990s) to conventional EBRT (1990s–2000s) to IMRT + SIB (2000s). With median alive follow-up of 6 years (0.3–28 years), the 5-year LC, LRC, and OS rates were 80%, 73%, and 51%. There was no difference in distribution of gender, age, stage among treatment modalities. Definitive chemoRT had improved LRC (HR 1.6) and OS (HR 1.7) compared to definitive RT. IMRT + SIB had improved LRC (HR 3.2), DFS (HR 3.4), and OS (HR 3.0) compared to conventional EBRT. Over the past 30 years, BOT SCC treatment has undergone major paradigm shifts that incorporate nonsurgical functional preservation, concurrent chemotherapy, and advanced RT techniques. Excellent locoregional control and survival outcomes are associated with accelerated IMRT with chemotherapy

    Breast cancer is a major health problem in Egypt. Her-2/Neu gene is routinely assessed for all breast cancer patients primarily by immunohistochemistry. At National Cancer Institute (NCI), Cairo University, Flourescence In Situ hybridization (FISH) analysis of Her-2/Neu gene is carried out for Her-2/Neu score 2 and for some cases of score 3 (particularly those assessed outside NCI). The test is performed essentially on the primary tumor. However, some situations require testing on corresponding lymph node metastases. There is a debate about the concordance between Her-2/Neu status in the primary tumor and synchronous lymph node metastases in various studies. The aim of this study was to test for the concordance between Her-2/Neu status in the primary breast tumor and corresponding axillary nodal metastases. This is a retrospective study in which FISH analysis of Her-2/Neu was carried out simultaneously on archived material of 50 cases previously diagnosed as invasive duct carcinoma and the corresponding nodal metastases from the Pathology Department, NCI. There was complete concordance between Her-2 status in the primary tumor and the corresponding axillary lymph node metastatic deposits in which Her-2 was amplified in 44% of the studied cohort of Egyptian patients. Her-2/Neu gene assessed by FISH analysis on synchronous lymph node metastases is strongly correlated with the primary tumor. Hence, it is justified to carry out the Her-2/Neu test on synchronous lymph nodes to decide on whether to carry out anti-Her-2/Neu target therapy. Further studies on other metastatic sites is recommended.

    Purpose: To evaluate the treatment results of patients (pts) with Figo stage IB2, IIA, IIB cervical carcinoma (C.C.) treated with preoperative radio chemotherapy, followed by extended radical hysterectomy. Patients and methods: Retrospective study of 148 women treated to the Curie Institute for operable Figo Stage IB2 to IIB, biopsy proved C.C.. Among them, 70 pts, median age 46 years, were treated using the same regimen associating primary radio cis-platinum based chemotherapy,intracavitary LDR brachytherapy, followed by extended radical hysterectomy. Kaplan-Meier estimates were used to draw survival curves. Comparisons of survival distribution were assessed by the log-rank test. Results: Complete histological local-regional response was obtained in 56% of the pts (n = 39). Residual macroscopic or microscopic disease in the cervix was observed in 28 pts (40%). All but one had in situ microscopic residual C.C.. Lateral residual disease in the parametria was also present in nine pts, all with residual C.C.. Pelvic lymph nodes were free from microscopic disease in 56 pts (80%). Eight of 55 (11%) radiological N0 patients had microscopic nodal involvement, as compared to 6/15 (40%) radiological N1 (p = 0.03). Seventeen pts (25%) had residual cervix disease but negative nodes. After median follow-up of 40 months (range, 8-141), 38/70 patients (54.1%) are still alive and free of disease, six (8.6%) alive with disease, and 11 (15.8%) patients were lost for follow-up but free of disease. Conclusion: The treatment of locally advanced C.C. needs a new multidisciplinary diagnostic and treatment approach using new therapeutic arms to improve the survival and treatment tolerance among women presenting this disease.

    To describe CT findings and differential points of cystic thymic lesions. We evaluated retrospectively total 19 masses with well marginated cystic lesions at thymic area on CT scans. They were 10 teratomas, 3 congenital thymic cysts, 2 multilocular thymic cysts(associated with thymoma and myasthenia gravis in each), 2 cysts Assciated with thymic Hodgkin's lymphomas an ectopic parathyroid cyst, and an infected thymic cyst. The radiological abnormalities evaluated were thickness of the wall, presence or abscene of septa, mural nodule, solid component, calcification and fat component. All three cases of congenital thymic cysts and an ectopic parathyroid cyst appeared as thin-walled unilocular cyst with homogeneous internal density and without identifiable solid component. In multilocular thymic cyst, there were thick wall and solid components(n =2), thick internal septa and calcifications(n = 1). The cysts of teratomas manifested thick walls(n = 9), internal septa(n = 4), calcifications(n = 6), fat components(n = 4), and solid components(n = 4). Cysts in Hodgkin's diseases appeared as multilocular or unilocular and had thick wall and septa without calcification. Infected thymic cyst presented with multilocular cystic mass with identifiable wall and septa, calcification, and solid components. The thymic diseases with cystic lesion include teratomas, congenital thymic cysts, multilocular thymic cysts, parathyroid cyst, and Hodgkin's disease. Congenital thymic cyst and ectopic parathyroid cyst are thin-walled unilocular cystic lesions. Cystic lesions associated with teratoma, Hodgkin's disease, and multilocular thymic cyst are thick-walled cystic lesions with or without solid component.

    Purpose/Objective(s): This study aimed to analyze outcomes in a multi-institutional cohort of patients with advanced or recurrent renal cell carcinoma (RCC) who were treated with intraoperative radiation therapy (IORT). Methods and Materials: Between 1985 and 2010, 98 patients received IORT for advanced or locally recurrent RCC at 9 institutions. The median follow-up time for surviving patients was 3.5 years. Overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS) were estimated with the Kaplan-Meier method. Chained imputation accounted for missing data, and multivariate Cox hazards regression tested significance. Results: IORT was delivered during nephrectomy for advanced disease (28%) or during resection of locally recurrent RCC in the renal fossa (72%). Sixty-nine percent of the patients were male, and the median age was 58 years. At the time of primary resection, the T stages were as follows: 17% T1, 12% T2, 55% T3, and 16% T4. Eighty-seven percent of the patients had a visibly complete resection of tumor. Preoperative or postoperative external beam radiation therapy was administered to 27% and 35% of patients, respectively. The 5-year OS was 37% for advanced disease and 55% for locally recurrent disease. The respective 5-year DSS was 41% and 60%. The respective 5-year DFS was 39% and 52%. Initial nodal involvement (hazard ratio [HR] 2.9-3.6, P<.01), presence of sarcomatoid features (HR 3.7-6.9, P<.05), and higher IORT dose (HR 1.3, P<.001) were statistically significantly associated with decreased survival. Adjuvant systemic therapy was associated with decreased DSS (HR 2.4, P=.03). For locally recurrent tumors, positive margin status (HR 2.6, P=.01) was associated with decreased OS. Conclusions: We report the largest known cohort of patients with RCC managed by IORT and have identified several factors associated with survival. The outcomes for patients receiving IORT in the setting of local recurrence compare favorably to

    The goal of this study was to perform a retrospective analysis of the ultrasonographic findings associated with low-grade endometrial stromal sarcoma. Ten pathologically confirmed cases of low-grade endometrial stromal sarcoma at our institution from January 2007 to April 2014 were retrospectively reviewed. All patients underwent a preoperative transvaginal ultrasound. Two radiologists came to a consensus regarding the location, size, margin, and echogenicity of the tumor, as well as the presence of intratumoral cystic degeneration and its extent and configuration. Low-grade endometrial stromal sarcoma manifested as an intramural mass protruding into the endometrial cavity (n=6) or as a purely intramural mass (n=4). The maximal diameter of the lesion ranged from 4 to 9.1 cm (mean, 6.2 cm). The imaging features of low-grade endometrial stromal sarcoma were variable: six cases involved predominantly solid masses containing cystic degeneration, one was a predominantly unilocular cystic mass, two were ill-defined infiltrative solid masses, and one was a well-defined solid mass. Among the seven cases with internal cystic degeneration, five patients showed a multiseptated cystic area or a cystic area with multiple small clusters, while a unilocular cystic area within the tumor was found in two patients. Low-grade endometrial stromal sarcoma is associated with variable ultrasonographic findings with regard to the location, margin, and configuration of the lesion. Multiseptated cystic areas and multiple small areas of cystic degeneration are common.

    Full Text Available Autoimmune pancreatitis (AIP can be chronic or recurrent, but frequently completely reversible after steroid treatment. A cystic lesion in AIP is a rare finding, and it can mimic a pancreatic cystic neoplasm. Difficulties in an exact diagnosis interfere with treatment, and surgery cannot be avoided in some cases. We report the history of a 63-year-old male presenting with jaundice and pruritus. AIP was confirmed by imaging and elevated IgG4 blood levels, and the patient completely recovered after corticosteroid therapy. One year later, he presented with a recurrent episode of AIP with elevated IgG4 levels, accompanied by the appearance of multiple intrapancreatic cystic lesions. All but 1 of these cysts disappeared after steroid treatment, but the remaining cyst in the pancreatic head was even somewhat larger 1 year later. Pancreatoduodenectomy was finally performed. Histology showed the wall of the cystic lesion to be fibrotic; the surrounding pancreatic tissue presented fibrosis, atrophy and lymphoplasmacytic infiltration by IgG4-positive cells, without malignant elements. Our case illustrates the rare possibility that cystic lesions can be part of AIP. These pseudocysts appear in the pancreatic segments involved in the autoimmune disease and can be a consequence of the local inflammation or related to ductal strictures. Steroid treatment should be initiated, after which these cysts can completely disappear with recovery from AIP. Surgical intervention may be necessary in some exceptional cases.

    Full Text Available A Miniature Pinscher developed acute blindness and behavioral changes. On magnetic resonance imaging (MRI, there were multiple small intra-axial cystic lesions, and primary differential diagnoses included primary or metastatic neoplasia and neurocysticercosis. These cystic lesions were subsequently diagnosed histopathologically as disseminated choroid plexus carcinoma. This is only the second documented description of this diagnosis in a dog, but both patients had very similar MRI findings. This patient adds to the literature about the MRI characteristics of choroid plexus tumors and indicates that choroid plexus tumor should be considered as a possible cause of small multifocal intra-axial cystic brain lesions in dogs, regardless of whether a primary intraventricular lesion is visible.

    Fibroadenomas with a predominant cystic change are called cystic fibroadenomas. These are extremely rare forms of fibroadenomas and only one case has been reported so far. They are classified under the category of complex fibroadenomas. Complex fibroadenomas are a rare variant of fibroadenomas occurring in elderly females. They are characterized by presence of one of the complex features along with the usual patterns of fibroadenoma such as cysts more than 3 mm, papillary apocrine metaplasia, or sclerosing adenosis. Patients with these lesions have higher chances of developing carcinoma of breast.

    We retrospectively reviewed MRI findings of 17 patients with 3 histologically proven cystic pituitary tumors. They consisted of 10 cystic pituitary adenomas, 4 craniopharyngiomas and 3 Rathke`s cleft cysts. We analyzed the following MRI parameters such as cyst wall appearance, enhancement pattern of cyst wall, location of residual pituitary gland and location of tumor. They were clinically significant parameters for histological differentiation. Even though combinations of such MRI parameters helped for more accurate preoperative diagnosis, the differentiation between craniopharyngioma and Rathke`s cleft cyst was difficult in some cases.

    Two dogs with signs of forebrain disease had hypodense lesions on computed tomography evaluation. Magnetic resonance imaging of the first dog showed a hypointense lesion on the T1-weighted scan and a hyperintense lesion on T2-weighted scanning. At surgery, both dogs had a primary cystic intracranial lesion, and the abnormal tissue adjacent to the cyst had histological features of meningioma. Each dog underwent whole brain irradiation after surgery, and 1 dog lived for 3 years after treatment. While uncommon, meningioma should be considered as a differential diagnosis in dogs with cystic intracranial lesions

    Neuroblastoma is the most common neonatal malignant tumor. Hemorrhage and necrosis are usual features of this lesion, but it rarely presents a totally cyst form. We report a case of cystic neuroblastoma detected on prenatal ultrasound and stress the need to include it in the differential diagnosis of cystic abdominal masses in the newborn. Ultrasound is the method of choice for assessing abdominal masses in children. However, magnetic resonance has been shown to be more advantageous for the study and follow-up of neuroblastomas.

    Beger, Hans G; Schwarz, Michael; Poch, Bertram

    2012-11-01

    Cystic neoplasms of the pancreas are diagnosed frequently due to early use of abdominal imaging techniques. Intraductal papillary mucinous neoplasm, mucinous cystic neoplasm, and serous pseudopapillary neoplasia are considered pre-cancerous lesions because of frequent transformation to cancer. Complete surgical resection of the benign lesion is a pancreatic cancer preventive treatment. The application for a limited surgical resection for the benign lesions is increasingly used to reduce the surgical trauma with a short- and long-term benefit compared to major surgical procedures. Duodenum-preserving total pancreatic head resection introduced for inflammatory tumors in the pancreatic head transfers to the patient with a benign cystic lesion located in the pancreatic head, the advantages of a minimalized surgical treatment. Based on the experience of 17 patients treated for cystic neoplastic lesions with duodenum-preserving total pancreatic head resection, the surgical technique of total pancreatic head resection for adenoma, borderline tumors, and carcinoma in situ of cystic neoplasm is presented. A segmental resection of the peripapillary duodenum is recommended in case of suspected tissue ischemia of the peripapillary duodenum. In 305 patients, collected from the literature by PubMed search, in about 40% of the patients a segmental resection of the duodenum and 60% a duodenum and common bile duct-preserving total pancreatic head resection has been performed. Hospital mortality of the 17 patients was 0%. In 305 patients collected, the hospital mortality was 0.65%, 13.2% experienced a delay of gastric emptying and a pancreatic fistula in 18.2%. Recurrence of the disease was 1.5%. Thirty-two of 175 patients had carcinoma in situ. Duodenum-preserving total pancreatic head resection for benign cystic neoplastic lesions is a safe surgical procedure with low post-operative morbidity and mortality.

    To evaluate the efficacy and safety of high-dose, hypofractionated proton beam therapy for hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). In this single-arm, phase II, multi-institutional study, 92 patients with biopsy-confirmed HCC or ICC, determined to be unresectable by multidisciplinary review, with a Child-Turcotte-Pugh score (CTP) of A or B, ECOG performance status of 0 to 2, no extrahepatic disease, and no prior radiation received 15 fractions of proton therapy to a maximum total dose of 67.5 Gy equivalent. Sample size was calculated to demonstrate > 80% local control (LC) defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.0 criteria at 2 years for HCC patients, with the parallel goal of obtaining acceptable precision for estimating outcomes for ICC. Eighty-three patients were evaluable: 44 with HCC, 37 with ICC, and two with mixed HCC/ICC. The CTP score was A for 79.5% of patients and B for 15.7%; 4.8% of patients had no cirrhosis. Prior treatment had been given to 31.8% of HCC patients and 61.5% of ICC patients. The median maximum dimension was 5.0 cm (range, 1.9 to 12.0 cm) for HCC patients and 6.0 cm (range, 2.2 to 10.9 cm) for ICC patients. Multiple tumors were present in 27.3% of HCC patients and in 12.8% of ICC patients. Tumor vascular thrombosis was present in 29.5% of HCC patients and in 28.2% of ICC patients. The median dose delivered to both HCC and ICC patients was 58.0 Gy. With a median follow-up among survivors of 19.5 months, the LC rate at 2 years was 94.8% for HCC and 94.1% for ICC. The overall survival rate at 2 years was 63.2% for HCC and 46.5% ICC. High-dose hypofractionated proton therapy demonstrated high LC rates for HCC and ICC safely, supporting ongoing phase III trials of radiation in HCC and ICC. © 2015 by American Society of Clinical Oncology.

    The aim of this study was to assess the characteristics of papillary thyroid carcinoma (PTC) in patients aged 65 and older in order to predict postoperative recurrence based on the results of ultrasonographic surveillance. Among 1,494 patients (200 male and 1,294 female; mean age, 46.6±11.3 years) who underwent surgery for thyroid cancer at our institution between 2006 and 2015, we retrospectively enrolled 150 PTC patients (29 male and 121 female; mean age, 69.4±4.2 years). To identify the risk factors for recurrence, we analyzed age, gender, multiplicity, size, number, extrathyroidal extension (ETE) of the tumor, lymph node metastasis (LNM), type of surgery, and the dose of radioactive ablation using a Cox regression model to identify hazard ratios (HRs). Among the 115 asymptomatic patients with PTCs detected by screening ultrasonography (n=86), other cross-sectional imaging modalities (computed tomography or positron emission tomography-computed tomography, n=13), or incidentally through a surgical specimen (n=16), 78 patients were confirmed to have papillary thyroid microcarcinomas (PTMCs). The other 35 patients presented with palpable neck masses (n=25), vocal cord palsy (n=9) or blood-tinged sputum (n=1). During the follow-up period (mean, 43.6 months), 17 patients (12.5%) experienced recurrence in the neck. None of the patients died due to PTC-related recurrence or distant metastasis during the follow-up period. Cox regression analysis demonstrated that tumor size (HR, 2.12; P<0.001) and LNM (central LNM: HR, 9.08; P=0.004; lateral LNM: HR, 14.71; P=0.002; both central and lateral LNM: HR, 58.41; P<0.001) significantly increased the recurrence rate. ETE, LNM, and recurrence were significantly less frequent in PTMCs than in non-PTMC (all P<0.001). PTCs of small size and absent LNM showed significantly better prognoses in patients 65 years and older.

    Objective: To analyze the CT findings of pelvic cystic echinococcosis, and to assess the value of CT examination. Methods: Twenty-one cases of pelvic cystic echinococcosis, confirmed by clinical and pathological results, underwent CT scanning. CT characters were analyzed and compared with pathology. Results: Simple cystic echinococcosis appeared as single or multiple cystic lesions with round or oval shape, smooth boundary, and no enhancement after contrast medium administration in 3 cases; Different number and size of daughter cysts were detected inside the lesion in 17 cases; Ruptured lesions showed 'double wall', 'water snake', or 'flow ribbon' signs in 4 cases; Increase density of contents and enhanced cystic wall were demonstrated in 2 cases with companied infections. In 8 cases, calcification occurred on the cystic wall or extended inside the content. Conclusion: CT could accurately demonstrate the location, appearance, internal structure, and adjacent situation of the cystic echinococcosis, providing valuable information for correct diagnosis and treatment

    The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyma and renal collecting systems are invaded simultaneously. We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renal contour bulging or reinform shape, location of mass center, intact parenchyma overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cell carcinoma, where a and nine of 12 cases of transitional cell carcinoma maintained the reinform appearance. This is significant statiscal difference between the two(P<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(P<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, where as 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(P<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(P<0.05). CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reinform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change

    Genetic counseling is an important part of health care in patients with cystic fibrosis or respiratory diseases associated with the CFTR (cystic fibrosis transmembrane conductance regulator) gene, including certain types of allergic bronchopulmonary aspergilloses or bronchial diseases (diffuse bronchiectasia). The basic goal is to provide patients with information on the transmission of cystic fibrosis and to asses the risk of recurrence. This risk is determined from molecular biology analyses examining the CFTR gene. Genotyping is the only means of screening for the heterozygous state, frequent in the French population (about 1/30). Because of the large number of mutated alleles not covered entirely by the genetic tests, there remains a question of probability expressed as a residual risk of a heterozygous state. A prenatal genotype diagnosis should be proposed to heterozygous couples who have a 25% risk of having a diseased child. Technically, this is almost always possible and the results are highly reliable. Nevertheless, there remains the risks related to sample taking and the ethical issue about which the patients must be informed. Management of these at risk couples who desire a child must be based on a multidisciplinary approach, particularly important when one of the parents has overt cystic fibrosis.

    Thyroid follicular carcinoma is able to produce metastatic lesions before the vanishing of the primary lesion. We present a case of a woman with a lytic, solitary, asymptomatic parietal bone lesion of 2 years of evolution. Autopsy revealed a thyroid gland with two small cystic areas and renal metastasis. Thyroid carcinoma should be included in the differential diagnosis in cases of lytic bone lesions with long evolution in patients 60 years of age or older.

    2012-05-01

    Despite the inclusion of extra vitamin D in their regimen of fat-soluble vitamin supplementation, cystic fibrosis patients remain chronically depleted of vitamin D. The persistence of suboptimal vitamin D status is often blamed on the maldigestion and malabsorption of fat. However, the mitigated success of recent clinical trials with high-dose vitamin D supplementation suggests that vitamin D bioavailability might be impaired in these patients. Given the growing understanding of the importance of this vitamin in the regulation of multiple biological functions beyond skeletal health, the present review analyzes the current literature by addressing each step of vitamin D metabolism and action in the context of this life-limiting pathology. In addition, it highlights the importance of vitamin D in relation to organs and or conditions affected by cystic fibrosis. © 2012 International Life Sciences Institute.

    1988-10-01

    A nonerosive form of rheumatoid arthritis (R.A.) was found in 62 patients out of 660 patients with R.A.. These 62 patients exhibit slowly progressive cystic changes in about the same joints in which usually erosions develop in classic R.A.. The E.S.R. is often low, half of the patients remained seronegative and there are 35 males and 27 females in the group. A smaller group of 15 out of these patients could be followed from a stage wherein the radiographs were normal to a stage of extensive cystic changes, over a period of at least 6 years. An attempt is made to delineate this group within the rheumatoid arthritis disease entity.

    Cystic fibrosis (CF) is a multi-systemic disease with major impact on the lungs. Pulmonary manifestation is crucial for the prognosis and life expectancy of patients. Imaging modalities and lung function tests reflect the pulmonary status in these patients. The standard imaging modality for diagnosis and follow-up of pulmonary changes is chest x-ray. The gold standard for the detection of parenchymal lung changes remains high resolution computed tomography (HRCT), but this is not used routinely for CF-patients due to radiation exposure. Magnetic resonance imaging (MRI) used to be of no importance in monitoring cystic fibrosis lung disease, as shown in studies from the 1980s and early 1990s. The continuing improvement of MRI techniques, however, has allowed for an adequate application of this non-radiation method in diagnosing the major pulmonary findings in CF, in addition to the assessment of lung function.

    Cystic fibrosis is the most common life-shortening recessively inherited disorder in the Caucasian population. The genetic mutation that most frequently provokes cystic fibrosis (ΔF508) appeared at least 53,000years ago. For many centuries, the disease was thought to be related to witchcraft and the "evil eye" and it was only in 1938 that Dorothy H. Andersen characterized this disorder and suspected its genetic origin. The present article reviews the pathological discoveries and diagnostic and therapeutic advances made in the last 75 years. The review ends with some considerations for the future. Copyright © 2015 Elsevier España, S.L.U. and AEEH y AEG. All rights reserved.

    Urethral carcinoma in 2 females has been treated with irradiation together with adjunct chemotherapy. In case 1, a 73-year-old female with squamous cell carcinoma was successfully treated with irradiation of 4,000 rad and peplomycin of 60 mg intravenously given. She has been free from the disease for the past 43 months. In case 2, a 61-year-old female with transitional cell carcinoma was initially treated with irradiation of 5,000 rad together with peplomycin 90 mg, which was followed by another 5,000 rad irradiation. The tumor recurred and the patient was operated on for cystourethrectomy and partial resection of the vagina. A further chemotherapy of cisplatin, peplomycin, and mitomycin C was instituted. She died of the tumor recurrence 23 months after the first visit to our clinic. Diagnosis and treatment modalities on the female urethral carcinoma are briefly discussed. (author)

    2007-01-01

    Purpose: To compare clinical outcomes of patients with carcinomas of the paranasal sinuses and nasal cavity according to decade of radiation treatment. Methods and Materials: Between 1960 and 2005, 127 patients with sinonasal carcinoma underwent radiotherapy with planning and delivery techniques available at the time of treatment. Fifty-nine patients were treated by conventional radiotherapy; 45 patients by three-dimensional conformal radiotherapy; and 23 patients by intensity-modulated radiotherapy. Eighty-two patients (65%) were treated with radiotherapy after gross total tumor resection. Nineteen patients (15%) received chemotherapy. The most common histology was squamous cell carcinoma (83 patients). Results: The 5-year estimates of overall survival, local control, and disease-free survival for the entire patient population were 52%, 62%, and 54%, respectively. There were no significant differences in any of these endpoints with respect to decade of treatment or radiotherapy technique (p > 0.05, for all). The 5-year overall survival rate for patients treated in the 1960s, 1970s, 1980s, 1990s, and 2000s was 46%, 56%, 51%, 53%, and 49%, respectively (p = 0.23). The observed incidence of severe (Grade 3 or 4) late toxicity was 53%, 45%, 39%, 28%, and 16% among patients treated in the 1960s, 1970s, 1980s, 1990s, and 2000s, respectively (p = 0.01). Conclusion: Although we did not detect improvements in disease control or overall survival for patients treated over time, the incidence of complications has significantly declined, thereby resulting in an improved therapeutic ratio for patients with carcinomas of the paranasal sinuses and nasal cavity

    Full Text Available Introduction: Cystic Fibrosis is the most common recessive autosomic genetic disease among Caucasians. It's caused by mutations in the gene that decodes regulatory protein for transmembrane conductance, resulting in defective transport of chlorine. Objective: Review the literature about Cystic Fibrosis, with emphasis on otorhinolaryngologic manifestations. Method: The online Pub Med databases were researched and we applied the following search terms Fibrosis Cystic and Sinusitis, and Mucoviscidosis and Sinusitis. Conclusions: Although it is not the main cause of death, the otorhinolaryngologic manifestations of the Cystic Fibrosis bring important morbidity to these patients.

    Purpose: Controversies exist regarding the use of radiation therapy in the treatment of vulvar carcinoma. A retrospective review was performed to evaluate our institution's experience with surgery and radiation for this disease. Methods and Materials: The medical records of 47 patients treated for squamous cell carcinoma of the vulva at our institution (1974-1992) were reviewed for TNM stage (AJCC criteria), treatment modality, and associated 5-year local control and survival based on Kaplan-Meier analysis. Results: Twenty-eight patients (60%) presented with Stage I and II disease and their 5-year survival was 69%. Stage III patients accounted for 12 (25%) of the patients and their 5-year survival was 73%. Seven patients presented with Stage IV disease and five died within 13 months of diagnosis after predominantly palliative therapy. The 40 patients with Stages I, II, and III disease were treated aggressively and were further evaluated for treatment-modality-associated survival and local control. Radiation therapy was used as primary treatment in nine patients, of whom seven were treated with radiation alone and two were treated postoperatively after wide excision. Surgery alone was performed in 31 patients consisting of either radical vulvectomy (20 patients) or wide excision (11 patients). When comparing outcomes of radical vulvectomy vs. radiation therapy, we noted that the 5-year actuarial survivals were comparable (74% for either modality), despite the presence of more favorable prognostic factors in the group treated with radical vulvectomy. Patients treated with wide excision alone had a trend for a poorer 5-year actuarial survival (51%) and local control (50%). Conclusions: Radical vulvectomy offers good locoregional control and survival. This retrospective review further supports the use of radiation therapy with conservative surgery as an alternative treatment option for patients with vulvar carcinoma treated with curative intent. In contrast, the use of

    The benign cystic peritoneal mesothelioma (BCPM) is a rare neoplasm affecting mainly females at reproductive age. The natural history and physiopathology of the BCPM are not entirely known. It is mainly characterized by the lack of malignant elements, no tendency to metastasis and by a pervasive tendency to generate local recurrences after surgical removal. The clinical manifestations are insidious, uncharacteristic; the benign cystic peritoneal mesothelioma is often discovered during a surgical procedure addressing another condition. Imaging tests can raise the suspicion of BCPM but the diagnostic can only be confirmed by histopathological examination corroborated with an immunohistochemical analysis. There are no long term studies dictating a single therapeutic attitude but a high risk of local recurrences and the possibility of transformation into malignant mesothelioma have lead to the current tendency towards an aggressive treatment of the tumor. We present the case of a recurrent benign cystic peritoneal mesothelioma in a 40 years old female patient, emphasizing the therapeutic approach and the role of radical surgery in the treatment of BPCM.

    Full Text Available Cystic fibrosis (CF is the most common autosomal recessive disorder in Caucasian populations. Individuals with CF have seen significant increases in life expectancy in the last 60 years. As a result, previously rare complications are now coming to light. The most common of these is cystic fibrosis-related diabetes (CFRD, which affects 40–50% of CF adults. CFRD significantly impacts the pulmonary function and longevity of CF patients, yet a lack of consensus on the best methods to diagnose and treat CFRD remains. We begin by reviewing our understanding of the pathogenesis of CFRD, as emerging evidence shows the cystic fibrosis transmembrane conductance regulator (CFTR also has important roles in the release of insulin and glucagon and in the protection of β cells from oxidative stress. We then discuss how current recommended methods of CFRD diagnosis are not appropriate, as continuous glucose monitoring becomes more effective, practical, and cost-effective. Finally, we evaluate emerging treatments which have narrowed the mortality gap within the CF patient group. In the future, pharmacological potentiators and correctors directly targeting CFTR show huge promise for both CFRD and the wider CF patient groups.

    Full Text Available BACKGROUND Mass lesions of the breast require sonological evaluation in women of any age group. It is difficult to reach a diagnosis of the cause of the mass lesion without ultrasonographic correlation. This study aims at evaluating subjects who underwent ultrasonography for evaluation of cystic mass lesion of the breast. Objective- To evaluate subjects presented with cystic lesions of the breast using ultrasonography and to understand the management of different types of cystic lesions of breast. MATERIALS AND METHODS 80 sonologically detected cystic lesions of the breast were enrolled in the study and were followed up for a minimum period of 6 months. Study was conducted after IEC approval and written informed consent was obtained from each study participant. RESULTS Majority of the study subjects (36.25% were in the age range of 41-50 years. 53.75% of the study subjects had simple cysts. 88.3% of the study subjects with simple cysts underwent needle aspiration and 5 cysts required excision. 3 subjects with simple cysts required aspiration more than once. Two of the three subjects with galactocoele underwent aspiration and one subject developed infection which required antibiotics and excision. Intracystic papillary carcinoma were detected in 21.25% and invasive ductal carcinoma were seen in 20% of the study subjects. CONCLUSION The age group of patients presented with cystic lesions of breasts indicate probable lower awareness regarding self-examination of the breasts after 30 years of age. This is a matter of concern. Breast cysts are usually benign though some radiologically complex masses may be malignant. Another differential diagnosis could be tuberculosis which has to be kept in mind.

    We herein present a case of a left cervical cystic mass, for which the initial pathological diagnosis was branchial cleft cyst carcinoma (following complete mass excision). Thorough postoperative examinations, including with FDG positron emission tomography/computed tomography (PET/CT), revealed a primary tumor in the retromolar region of the left mandible. A 52-year-old female presented with a 2-month history of a painless, progressively enlarged left-sided neck mass. Fine-needle aspiration biopsy suggested a branchial cleft cyst. Physical examination revealed a 3 × 3-cm smooth, tender mass in the upper-left neck and anterior border of the sternocleidomastoid muscle. Examination using nasendoscopy and a strobolaryngoscope revealed no abnormalities of the nasal cavity, nasopharynx, oropharynx, hypopharynx or larynx. MRI of the neck revealed a solitary, round, cystic mass under the left parotid gland. The mass was excised completely. Pathologic results indicated a branchial cleft cyst carcinoma. According to the diagnostic criteria for a branchial cleft cystic carcinoma, PET/CT was performed to detect the occult primary site. PET/CT revealed high FDG uptake in the tooth root of the left mandible. Frozen sections of the mass were indicative of moderate, differentiated squamous cell carcinoma. The carcinoma in the retromolar region of the left mandible was locally excised under general anesthesia. A partial left maxillectomy, partial mandibulectomy, and left radical neck dissection were performed. The patient received postoperative concurrent chemoradiotherapy, and was disease-free at the 8-month follow-up. True branchial cleft cyst carcinoma is rare: once diagnosed, it should be distinguished from metastatic cystic cervical lymph and occult primary carcinoma. FDG PET/CT is useful in the identification of occult primary tumor.

    Aim: To report the magnetic resonance imaging (MRI) features of intracranial cystic meningiomas and compare these features in intra- and peritumoural cyst groups. Materials and methods: Fourteen cases of peritumoural cystic meningiomas were compared with 18 cases of intratumoural cystic meningiomas. All patients were examined using non-enhanced and contrast-enhanced MRI. Tumour location, tumour size, signal intensity, enhancement characteristics, and cystic changes were assessed. The MRI features were compared between the intra- and peritumoural cyst groups. Results: Most cystic meningiomas comprised two or more cysts. The solid parts of the tumours showed moderate or marked enhancement after the injection of contrast material. An enhanced cyst wall was found in six out of 14 cases in the peritumoural cyst group, but not in the intratumoural cyst group. Peritumoural cystic meningiomas were predominately located in the cerebral falx, whereas the intratumoural cystic meningiomas were predominantly found in frontal convexity (X 2 = 7.434, p = 0.024). The cysts were larger in the peritumoural cyst group than in the intratumoural cyst group (t = 5.274, p = 0.0258). Peritumoural oedema was more commonly found in the intratumoural cyst group (X 2 = 6.863, p = 0.008). Cystic meningiomas with solid parts located inside the cyst are reported for the first time. Conclusion: Cystic meningiomas, although uncommon, should be differentiated from other cystic intracranial lesions. Peri- and intratumoural cystic meningiomas have distinct MRI features. The present study provides the first report of two lesions with solid parts located inside the cyst, as well as one lesion with a calcified solid nodule and haemorrhage within the cyst.

    A 69-year-old man with multiple skin lesions on his face, neck and upper torso, which first appeared in the 3rd decade of his life, was admitted to our hospital. He had cystic changes in his lungs noted on chest computed tomography (CT) scanning, as well as a left kidney mass. This patient exhibited a rare complex of renal, cutaneous and pulmonary manifestations, eponymously named Birt-Hogg-Dube syndrome, with characteristic skin features (fibrofolliculomas, trichodiscomas and acrochordons). This syndrome is due to an autosomal dominant germ-line mutation of the folliculin (FLCN) gene located at chromosome 17p11.2. Diagnosis and differentiation from other disease complexes including the skin, kidneys and lungs are important in prognostication and management of potentially life-threatening complications such as renal cell carcinoma and pneumothoraces.

    Evidence suggests that cystic fibrosis liver disease (CFLD) does not affect mortality or morbidity in patients with cystic fibrosis (CF). The importance of gender and age in outcome in CF makes selection of an appropriate comparison group central to the interpretation of any differences in mortality and morbidity in patients with CFLD.

    Cystic follicles are a significant cause of infertility in women, dairy cattle and sheep. Sheep were used as a model to identify factors that may elicit formation of cystic follicles. Insulin resistance and elevated LH activity were tested in overweight ewes because of associations among these factors and the formation of cystic follicles. Sheep were synchronized using a progesterone-releasing pessary and insulin resistance was induced during the synchronization period through administration of bovine somatotropin. Following removal of pessaries follicular growth was stimulated by treatment with eCG or eCG and hCG (PG-600). Follicular growth was monitored via daily transrectal ultrasonography and blood samples were collected for hormonal analyses. Six of 18 ewes had a subnormal or absent preovulatory gonadotropin surge and developed cystic follicles. Neither insulin resistance nor elevated LH activity were associated with formation of cystic follicles. Ewes that developed cystic follicles were heavier (93 +/- 4 kg) than ewes that ovulated (81 +/- 3 kg; P = 0.02). Furthermore, following pessary removal and initiation of daily ultrasonography, ewes that developed cystic follicles lost body weight (-3 +/- 1%), while ovulatory ewes continued to gain body weight (1 +/- 1%; P = 0.005). It is speculated that in heavy ewes metabolic factors associated with acute body weight loss inhibit the positive feedback of estradiol and thereby suppress the preovulatory gonadotropin surge leading to formation of cystic follicles.

    The most common cystic malformations of the neck are the result of abnormal embryogenesis involving the thyroglossal duct (TGD), lymphatic primordia and the branchial apparatus. When the basic embryology of these structures is considered, a reasonable differential diagnosis - and in some cases a definitive diagnosis - can be achieved based on the location and the imaging characteristics of the cystic mass.

    Full Text Available Metastasis to the thyroid gland is very rare. Recently, we experienced a case of thyroid metastasis from breast cancer accompanying a papillary thyroid. A 51-year-old female patient presented with a palpated lymph node on her left lateral neck. The patient had undergone a left modified radical mastectomy followed by chemotherapy and hormonal therapy 12 years prior. Ultrasonography of the neck revealed a malignant looking nodule at the left thyroid lobe, measuring 0.9 × 0.9 cm, and several cystic nodules at the right thyroid lobe. Ultrasonography of the neck additionally revealed a malignant looking lymph node at the right level VI. Fine-needle aspiration of the left thyroid lobe resulted in a diagnosis of papillary thyroid carcinoma and that of the right level VI in Hurthle cell lesion. The patient had a total thyroidectomy with selective dissection of the left neck node. Pathologic assessment of the specimen revealed metastatic carcinoma from the breast carcinoma and papillary thyroid carcinoma. Although the thyroid gland is highly vascularized, metastasis of malignant tumors to the thyroid is relatively rare and detection of metastasis shows a low frequency. So a careful evaluation of thyroid tumor should be considered in a patient with a history of other malignancy.

    Full Text Available Abstract Background Hydatidosis is a zoonosis caused by Echinococcus granulosus, and ingesting eggs released through the faeces from infected dogs infects humans. The location of the hydatid cysts is mostly hepatic and/or pulmonary, whereas musculoskeletal hydatidosis is very rare. Case presentation We report an unusual case of primary muscular hydatidosis in proximity of the big adductor in a young Sicilian man. The patient, 34 years old, was admitted to the Department of Infectious and Tropical Diseases for ultrasonographic detection, with successive confirmation by magnetic resonance imaging, of an ovular mass (13 × 8 cm in the big adductor of the left thigh, cyst-like, and containing several small cystic formations. Serological tests for hydatidosis gave negative results. A second drawing of blood was done 10 days after the first one and showed an increase in the antibody titer for hydatidosis. The patient was submitted to surgical excision of the lesion with perioperatory prophylaxis with albendazole. The histopathological examination of the bioptic material was not diriment in the diagnosis, therefore further tests were performed: additional serological tests for hydatidosis for the evaluation of IgE and IgG serotype (Western Blot and REAST, and molecular analysis of the excised material. These more specific serological tests gave positive results for hydatidosis, and the sequencing of the polymerase chain reaction products from the cyst evidenced E. granulosus DNA, genotype G1. Any post-surgery complications was observed during 6 following months. Conclusion Cystic hydatidosis should always be considered in the differential diagnosis of any cystic mass, regardless of its location, also in epidemiological contests less suggestive of the disease. The diagnosis should be achieved by taking into consideration the clinical aspects, the epidemiology of the disease, the imaging and immunological tests but, as demonstrated in this case, without

    Internal irradiation with P-32 chromic phosphate and Au-198 colloid was used to treat cystic craniopharyngioma. A newly developed dosimetric formula, by which the radiation dose can be calculated simultaneously at the cyst wall and at a point far from the radioactive source and the untoward effect of irradiation on surrounding brain tissue can be eliminated, especially in cases in which the wall is thin and can be penetrated by beta emission, was used. Radioactive phosphate or gold was injected into eight craniopharyngioma cysts throught the Ommaya reservoir and a tube inserted at the first craniotomy. All cysts were effectively treated for 3 to 33 months, to eliminate fluid retention or collapse. A collapsed cyst was removed at the second craniotomy and irradiation was histologically shown to be effective. Oculomotor palsy, a side effect of irradiation, occurred 10 days after the injection of 5 mc of P-32 chromic phosphate only in a case of small cysts (5.0 ml) in the supra- and intracellular regions. The thickness of the cyst wall was less than 0.5 mm and the oculomotor nerves were thought to adhere to the wall. Not only the amount of wall dose but also the thickness of the wall and localization of the cyst are important factors in internal irradiation. Sufficient and safer doses which kill tumor cells in the wall and have no side effects, are 9,000 to 30,000 rad. Internal irradiation can be used to treat large cysts of more than 10 ml which are supposedly difficult to remove radically and or multiple cysts. It is effective not only for cystic craniopharyngioma but also for intracrania cystic tumors other than craniopharyngioma, if dosimetry is accurate. (J.P.N.)

    The life expectancy of patients with cystic fibrosis (CF) has steadily increased over recent decades with a corresponding increase in the frequency of complications of the disease. Radiologists are increasingly involved with managing and identifying the pulmonary complications of CF. This article reviews the common manifestations of CF lung disease as well as updating radiologists with a number of less well-known complications of the condition. Early and accurate detection of the pulmonary effects of CF are increasingly important to prevent irreversible lung damage and give patients the greatest possibility of benefiting from the new therapies becoming available, which correct the underlying defect causing CF

    Chronic liver disease is one of the major complications of cystic fibrosis (CF). Significant liver disease is seen in 13-25% of children with CF. Improved life expectancy and prolonged follow-up have favored better characterization of the hepatic manifestations of CF and allowed direct observation of an increasing number of liver-related events. Liver disease typically develops in the first decade of life, with the incidence dropping rapidly after the age of 10 years. The wide spectrum of liver disease ranging from asymptomatic gallbladder abnormalities to biliary cirrhosis will be reviewed in this article

    2016-08-01

    Cystic fibrosis is frequently complicated by endocrine disorders. Diabetes can be expected to affect most with CF and pancreatic insufficiency and varies widely in age of onset, but early identification and treatment improve morbidity and mortality. Short stature can be exacerbated by relative delay of puberty and by use of inhaled corticosteroids. Bone disease in CF causes fragility fractures and should be assessed by monitoring bone mineral density and optimizing vitamin D status. Detecting and managing endocrine complications in CF can reduce morbidity and mortality in CF. These complications can be expected to become more common as the CF population ages.

  20. Gut-associated Lymphoid Tissue (GALT) Carcinoma or Dome Carcinoma?

    Rubio, Carlos A; Schmidt, Peter T

    2016-10-01

    The vast majority of colorectal carcinomas (CRCs) evolve from mucosa not associated to lymphoid tissues aggregates via the adenoma-carcinoma sequence or via the serrated pathway. Rarely CRCs evolve from gut mucosa associated to lymphoid tissue (GALT). Based on the presence of a circumscribed elevation in the colorectal mucosa, GALT carcinomas are also referred to as dome carcinomas (DC). Descriptions of the surface mucosa covering 21 GALT-CRCs appearing in pathological reports were reviewed. Three of the 21 GALT-CRCs fulfilled the criteria of dome carcinoma. Of the remaining 18 GALT-CRCs, nine were described as polypoid lesions, five as plaque-like lesions, two as sessile elevated lesions or mass, one as ulcerated and one as histological finding. Hence, only 14.3% (n=3) of the 21 GALT-CRCs displayed a dome configuration, whereas the majority, 85.7% (n=18), exhibited structures other than dome shapes at gross or at histologic examination. It becomes apparent that by using "dome" in addressing carcinomas in the colorectal mucosa, many cases of GALT carcinomas might be overlooked. Another drawback of using the "dome" nomenclature is that dome-like outlines may be detected in small metastatic tumors in the submucosa or in small colorectal carcinomas not arising from GALT mucosa. Instead, by using "GALT carcinoma", that is the histologic diagnosis in addressing these neoplasias, all cases of GALT-CRCs will be included.

    OBJECTIVE In 1999, the World Health Organization categorized large cell neuroendocrine carcinoma (LCNEC) of the lung as a variant of large cell carcinoma, and LCNEC now accounts for 3% of all lung cancers. Although LCNEC is categorized among the non-small cell lung cancers, its biological behavior has recently been suggested to be very similar to that of a small cell pulmonary malignancy. The clinical outcome for patients with LCNEC is generally poor, and the optimal treatment for this malignancy has not yet been established. Little information is available regarding management of LCNEC patients with brain metastases (METs). This study aimed to evaluate the efficacy of Gamma Knife radiosurgery (GKRS) for patients with brain METs from LCNEC. METHODS The Japanese Leksell Gamma Knife Society planned this retrospective study in which 21 Gamma Knife centers in Japan participated. Data from 101 patients were reviewed for this study. Most of the patients with LCNEC were men (80%), and the mean age was 67 years (range 39-84 years). Primary lung tumors were reported as well controlled in one-third of the patients. More than half of the patients had extracranial METs. Brain metastasis and lung cancer had been detected simultaneously in 25% of the patients. Before GKRS, brain METs had manifested with neurological symptoms in 37 patients. Additionally, prior to GKRS, resection was performed in 17 patients and radiation therapy in 10. A small cell lung carcinoma-based chemotherapy regimen was chosen for 48 patients. The median lesion number was 3 (range 1-33). The median cumulative tumor volume was 3.5 cm 3 , and the median radiation dose was 20.0 Gy. For statistical analysis, the standard Kaplan-Meier method was used to determine post-GKRS survival. Competing risk analysis was applied to estimate GKRS cumulative incidences of maintenance of neurological function and death, local recurrence, appearance of new lesions, and complications.

    After statistical analysis of the results of treatment (drawn from case reports and data collected over 31 years, which were investigated for histological findings, five-year survival rates, sex and age distributions, formation of metastases), the author came to the following conclusions: 1) Total strumectomy was the most succesful method of treatment. 2) In papillary tumours, 131-radioiodine led to the best results that were quite independent of the patient's age. It is of particular note that no further metastases appeared in those cases where metastatisation could be kept under control for the first two years. 3) Controversial findings were revealed as to the therapeutic success in follicular carcinomas. 4) Huethle's oncocytoma rather appears to be of a benign nature, major therapeutic problems are posed by anaplastic tumours. Further surgical measures are recommended to be taken especially in tumours showing structural differentiation. (TRV) [de

    Between 1969 and 1985, 73 patients with maxillary sinus cancers underwent surgical excision and postoperative radiotherapy. The clinical stage distribution by the AJC system was 3T 1 , 16T 2 , 32T 3 and 22 T 4 . Six patients had palpable lymphadenopathy at diagnosis. Surgery for the primary tumor consisted of partial or radical maxillectomy, and if disease stage indicated it, ipsilateral orbital exenteration. This was followed by radiation treatment delivered through a wedge-pair or three-field technique. All but 3 patients received 50-60 Gy in 2 Gy fractions to an isodose line defining the target volume. Elective neck irradiation (ENI) was nor routinely given. Clinically involved nodes were treated with definitive radiotherapy (5 patients) or combined treatment (1 patient). Forty-five patients had no evidence of disease at the last follow-up. The 5-year relapse-free survival for the whole group was 51 percent. The overall local control rate was 78 percent, Patients with larger tumors, particularly if they also had histological signs of nerve invasion, had a higher recurrence rate than others. The overall nodal recurrence rate without ENI was 38 percent for squamous and undifferen-tiated carcinoma, and only 5 for adenoid cystic carcinomas. Therefore, the current recommendation is to deliver elective nodal irradiation routinely to patients with squamous or undifferentiated carcinoma, except for those who have T 1 lesions. Treatment complications were vision impairment, brain and bone necrosis, trismus, hearing loss, and pituitary insufficiency. The incidence of major side effects was determined by disease extent and treatment technique. Many technical refinements were introduced in order to limit the dose to normal tissues in an attempt to reduce the complication rate. To what extent such practice influences the outcome will be determined from subsequent analysis. (author). 23 refs.; 2 figs.; 5 tabs

    Full Text Available Purpose: To study pattern of failure, locoregional control rates (LCR and disease free survival (DFS in post-operative patients of carcinoma oral tongue, and to study the impact of nodal dissection on DFS in stage I and II patients.Methods: 102 patients of carcinoma oral tongue treated between January 2009 and December 2013 were analyzed. All patients were operated for primary disease, but neck dissection was done in 78 (76.5% patients only. However, radiation to primary site along with neck region was received by all patients. Pattern of failure, LCR and DFS were estimated.Results: At median follow up of 12 months, 10.8% patients failed locally, 10.8% in nodal region, 2.9% both at local and nodal site, and 5.9% patients failed distally. 2 year LCR and DFS was 71.2%, 90.9%, 79.5%, 0% and 55.2%, 64.4%, 57.8%, 0% in stage I, II, III, IV respectively. 2 year DFS in stage I patients, who underwent nodal dissection and post-operative radiation (14 patients was 64.3% and in whom only neck irradiation was done (15 patients, it was 45.8%, however difference was not significant (p = 0.5. But in stage II patients, 33 patients who underwent nodal dissection and post-operative radiation, 2 year DFS was 85.4% and it was 21.4% in 7 patients who underwent neck radiation only, and difference showed trend towards significance (p = 0.05. 2 or more positive lymph nodes post dissection was the only poor prognostic factor that correlated with DFS (p = 0.02Conclusion: While in stage I, neck irradiation alone can be a possible alternative to neck dissection and post-operative radiation; for stage II, neck dissection is mandatory.

    Full Text Available Background: Accurate clinical staging is important for patient counseling, treatment planning, prognostication, and rational design of clinical trials. In head and neck squamous cell carcinoma, discrepancy between clinical and pathological staging has been reported. Objective: To evaluate any disparity between clinical and pathological tumor-node-metastasis (TNM staging in oral cavity squamous cell carcinoma (OCSCC patients and any impact of the same on survival. Materials and Methods: Retrospective chart review from year 2007 to 2013, at a tertiary care center. Statistical Analysis: All survival analyses were performed using SPSS for Windows version 15 (Chicago, IL, USA. Disease-free survival curves were generated using Kaplan-Meier algorithm. Results: One hundred and twenty-seven patients with OCSCC were analyzed. Seventy-nine (62.2% were males and 48 (37.8% females with a mean age at presentation 43.6 years (29-79 years. The highest congruence between clinical and pathological T-staging seen for clinical stage T1 and T4 at 76.9% and 73.4% with pathological T-stage. Similarly, the highest congruence between clinical and pathological N-stage seen for clinical N0 and N3 at 86.4% and 91.7% with pathological N-stage. Of clinically early stage patients, 67.5% remained early stage, and 32.5% were upstaged to advanced stage following pathological analysis. Of the clinically advanced stage patients, 75% remained advanced, and 25% were pathologically downstaged. This staging discrepancy did not significantly alter the survival. Conclusion: Some disparity exists in clinical and pathological TNM staging of OCSCC, which could affect treatment planning and survival of patients. Hence, more unified and even system of staging for the disease is required for proper decision-making.

    Purpose: To retrospectively assess the efficacy, toxicity, and prognostic factors of weekly low-dose docetaxel-based chemoradiotherapy for Stage III/IV oropharyngeal or hypopharyngeal carcinoma. Methods and Materials: Between 2001 and 2005, 72 consecutive patients with locally advanced oropharyngeal or hypopharyngeal carcinoma were treated with concurrent chemoradiotherapy (CCR; radiation at 60 Gy plus weekly docetaxel [10 mg/m 2 ]). Thirty of these patients also received neoadjuvant chemotherapy (NAC; docetaxel, cisplatin, and 5-fluorouracil) before concurrent chemoradiotherapy. Survival was calculated according to the Kaplan-Meier method. The prognostic factors were evaluated by univariate and multivariate analyses. Results: The median follow-up was 33 months, with overall survival, disease-free survival, and locoregional control rates at 3 years of 59%, 45%, and 52%, respectively. Thirty-six patients (50%) experienced more than one Grade 3 to 4 acute toxicity. Grade 3 mucositis occurred in 32 patients (44%), Grade 4 laryngeal edema in 1 (1%). Grade ≥3 severe hematologic toxicity was observed in only 2 patients (3%). Grade 3 dysphagia occurred as a late complication in 2 patients (3%). Multivariate analyses identified age, T stage, hemoglobin level, and completion of weekly docetaxel, but not NAC, as significant factors determining disease-free survival. Conclusions: Docetaxel is an active agent used in both concurrent and sequential chemoradiotherapy regimens. Mucositis was the major acute toxicity, but this was well tolerated in most subjects. Anemia was the most significant prognostic factor determining survival. Further studies are warranted to investigate the optimal protocol for integrating docetaxel into first-line chemoradiotherapy regimens, as well as the potential additive impact of NAC.

    Cystic lesions of the pancreas consist of a broad range of pathological entities. With the exception of the pancreatic pseudocyst, these are usually caused by pancreatic cystic neoplasms. Non-neoplastic pancreatic cystic and cystic-like lesions are extremely rare. In the present article, the surgical experience with these unusual entities over a 14-year period is reported. Between 1991 and 2004, all patients who underwent surgical exploration for a cystic lesion of the pancreas were retrospectively reviewed. Patients with a pancreatic pseudocyst were excluded. There were 106 patients of whom 8 (7.5%) had a final pathological diagnosis consistent with a non-neoplastic pancreatic cystic or cystic-like lesion, including 3 patients with a benign epithelial cyst, 2 with a pancreatic abscess (one tuberculous and one foreign body), 2 with mucous retention cysts and 1 with a mucinous non-neoplastic cyst. These eight patients are the focus of this study. There were six female and two male patients with a median age of 61.5 years (range, 41-71 years). All the patients were of Asian origin including seven Chinese and one Indian. Four of the patients were asymptomatic and their pancreatic cysts were discovered incidentally on radiological imaging for other indications. All the patients underwent preoperative radiological investigations, including ultrasonography, computed tomography or magnetic resonance imaging, which showed a cystic lesion of the pancreas. Three patients, all of whom were symptomatic, were diagnosed preoperatively with a malignant cystic neoplasm on the basis of radiological imaging. Two patients were eventually found to have a pancreatic abscess, one tuberculous and the other, secondary to foreign body perforation. The third patient was found on final histology to have chronic pancreatitis with retention cysts. The remaining five patients had a preoperative diagnosis of an indeterminate cyst; on pathological examination, they were found to have a benign

  10. Internal irradiation for cystic craniopharyngioma

    The authors report the results of internal irradiation with labeled chromic phosphate (32P) and gold-198 (198Au) colloid in eight cases of cystic craniopharyngiomas. They used a newly developed dosimetric formula, by which the radiation dose at the cyst wall and at any point far from the radioactive source can be calculated. Ten courses of irradiation in eight patients were carried out by injection of either 32P or 198Au colloid into the cyst through an Ommaya drainage system that had been placed at craniotomy. Follow-up studies ranging from 13 to 156 months revealed that all cysts were effectively treated, with elimination of fluid or collapse of the cyst. This was confirmed by Conray cystography and/or computerized tomography. Not only the dose delivered to the wall but also the thickness of the cyst wall and the location of the cyst are important factors in planning internal irradiation. A safe and adequate dose to the cyst wall could range between 9000 to 30,000 rads for craniopharyngioma. This treatment is suitable for large cysts that are thought to be difficult to remove radically, recurrent cysts resistant to previous treatment, or multiple cysts. Internal irradiation may also be applicable in other cystic intracranial tumors if dosimetry is calculated accurately

    Full Text Available We present a case of cystic lymphangioma of the mediastinum complicated with situs inversus totalis. The 70-year-old man underwent thoracoscopic resection of a mediastinal cystic tumor, which was diagnosed as cystic lymphangioma. Cystic lymphangiomas are congenital cystic abnormalities of the lymphatic system. The head and neck area is often involved while the mediastinum is rarely affected. The rarity of this case is further attributed to the coexistence of situs inversus totalis.

    Perinatal detection of neonatal suprarenal masses has increased. Here, we report an unusual case of an adrenal cystic neuroblastoma that presented as a purely cystic lesion upon initial postnatal ultrasonography (US) and showed rapid evolution to a mixed cystic and solid mass during follow-up US and MRI. We suggest a short-term (two weeks) follow-up US for neonatal adrenal cystic lesions, even if they appear as purely cystic.

    We describe a 24-year-old man with a cystic hygroma of the left side of the lower neck that led to sudden death. Cystic hygroma (cystic lymphangioma) is a congenital malformation of the lymphatic system. The patient, who had a tracheostomy because of airway obstruction from the cystic hygroma, was found dead with his tracheostomy tube on the floor next to him. Complications of cystic hygroma include infiltration of the neck causing airway obstruction, dysphagia, pain, and obstructive sleep apnea.

    People with cystic fibrosis and pancreatic insufficiency are at risk of fat soluble vitamin deficiency as these vitamins (A, D, E and K) are co-absorbed with fat. Thus, some cystic fibrosis centres routinely administer these vitamins as supplements but the centres vary in their approach of addressing the possible development of deficiencies in these vitamins. Vitamin A deficiency causes predominantly eye and skin problems while supplementation of vitamin A to excessive levels may cause harm to the respiratory and skeletal systems in children. Thus a systematic review on vitamin A supplementation in people with cystic fibrosis would help guide clinical practice. To determine if vitamin A supplementation in children and adults with cystic fibrosis:1. reduces the frequency of vitamin A deficiency disorders;2. improves general and respiratory health;3. increases the frequency of vitamin A toxicity. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises of references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of the most recent search of the Group's Cystic Fibrosis Trials Register: 07 April 2014. All randomised or quasi-randomised controlled trials comparing all preparations of oral vitamin A used as a supplement compared to either no supplementation (or placebo) at any dose and for any duration, in children or adults with cystic fibrosis (defined by sweat tests or genetic testing) with and without pancreatic insufficiency. No relevant studies for inclusion were identified in the search. No studies were included in this review. As there were no randomised or quasi-randomised controlled trials identified, we cannot draw any conclusions on the benefits (or otherwise) of regular administration of vitamin A in people with cystic fibrosis. Until further data are available, country or region specific guidelines on the use of

    Cystic fibrosis is a common autosomal recessive disorder with drastic respiratory symptoms, including shortness of breath and chronic cough. While most of cystic fibrosis treatment is dedicated to mitigating the effects of respiratory dysfunction, the potential effects of this disease on vocal parameters have not been systematically studied. We hypothesized that cystic fibrosis patients, given their characteristic respiratory disorders, would also present dysphonic symptoms. Given that voice disorders can severely impair quality of life, the identification of a potential cystic fibrosis-related dysphonia could be of great value for the clinical evaluation and treatment of this disease. We tested our hypothesis by measuring vocal parameters, using both objective physical measures and the GRBAS subjective evaluation method, in male and female cystic fibrosis patients undergoing conventional treatment and compared them to age and sex matched controls. We found that cystic fibrosis patients had a significantly lower vocal intensity and harmonic to noise ratio, as well as increased levels of jitter and shimmer. In addition, cystic fibrosis patients also showed higher scores of roughness, breathiness and asthenia, as well as a significantly altered general grade of dysphonia. When we segregated the results according to sex, we observed that, as a group, only female cystic fibrosis patients had significantly lower values of harmonic to noise ratio and an abnormal general grade of dysphonia in relation to matched controls, suggesting that cystic fibrosis exerts a more pronounced effect on vocal parameters of women in relation to men. Overall, the dysphonic characteristics of CF patients can be explained by dysfunctions in vocal fold movement and partial upper airway obstruction, potentially caused by the accumulation of mucus and chronic cough characteristic of CF symptomatology. Our results show that CF patients exhibit significant dysphonia and suggest they may

    2007-01-01

    Objective: To study the CT manifestations of carcinoma of ovary and the CT findings that mimic the carcinoma of ovary. Methods: CT findings were retrospectively studied in 47 cases of pelvic masses including 42 cases of carcinoma of ovary and 5 misdiagnosed as carcinoma of ovary. Misdiagnosis was made in 8 of the 42 cases of carcinoma of ovary. Non-contrast and enhanced CT scan were performed in all cases. Results: Pelvic or abdominal-pelvic masses were demonstrated in 92.4% cases. The lesions were parenchymatous, cystic, or cystic-parenchymatous masses, in which the parenchyma and septum were remarkably enhanced after the contrast agent was given intravenously. No mass was found in 7.6% cases, in which the ascites and thickening of the omentum were noted on CT images. Ascites was shown in 57.2% cases. Calicification was manifested in 19.0% cases. Abscess or tuberculosis located in pelvis could have the similar CT findings with cystic carcinoma of ovary, while these infectious lesions presented with regular or smooth wall and septum, instead of mural nodule. Another characteristic sign of abscess or tuberculosis was air density identified within the cavity of the cysts. Chocolate cysts with recent hemorrhage or subserous leiomyoma uteri with cystic degeneration were cystic-parenchymatous mass during the non-contrast enhanced scan. No enhancement could be revealed in parenchyma of the former and slight enhancement could be identified in the parenchymatous component of the latter. Conclusion: Contrast enhanced CT scan can demonstrate the structure of the mass and the adjacent organs, and reveal the enhancement of the lesions, which plays a valuable role in diagnosis or differential diagnosis of carcinoma of ovary with atypical CT findings.

    CT was undertaken and CT numbers were measured in 47 patients with cystic ovarian lesions. CT features particularly for chocolate cyst revealed the uniform thickness of the whole cystic wall, findings suggesting adhesion to the surrounding organs, circular or oval shape, and higher CT numbers within the cyst than those in the other cystic ovarian lesions. However, because these features are not always observed in cases of chocolate cyst, one should not rely solely on CT findings in the diagnosis of chocolate cyst. (Namekawa, K.)

    A 48-year-old woman was admitted to our hospital with a palpable mass in her lower abdomen. A left ovarian, cystic mass containing multiple mobile globules was seen on CT and MR images. The outer portion of the globules showed fat components on CT and fat-saturated T1-weighted MR images. Ultrasonography showed multiple echogenic, mobile globules with some sound attenuation and hyper echoic lines and dots within the cystic mass, which corresponded with the presence of lipid globules and hair shafts of ovarian mature cystic teratoma, respectively

    Several agents are used to clear secretions from the airways of people with cystic fibrosis. Mannitol increases mucociliary clearance, but its exact mechanism of action is unknown. The dry powder formulation of mannitol may be more convenient and easier to use compared with established agents which require delivery via a nebuliser. Phase III trials of inhaled dry powder mannitol for the treatment of cystic fibrosis have been completed and it is now available in Australia and some countries in Europe. This is an update of a previous review. To assess whether inhaled dry powder mannitol is well tolerated, whether it improves the quality of life and respiratory function in people with cystic fibrosis and which adverse events are associated with the treatment. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises references identified from comprehensive electronic databases, handsearching relevant journals and abstracts from conferences.Date of last search: 28 September 2017. All randomised controlled studies comparing mannitol with placebo, active inhaled comparators (for example, hypertonic saline or dornase alfa) or with no treatment. Authors independently assessed studies for inclusion, carried out data extraction and assessed the risk of bias in included studies. The quality of the evidence was assessed using GRADE. Six studies (reported in 50 publications) were included with a total of 784 participants.Duration of treatment in the included studies ranged from 12 days to six months, with open-label treatment for an additional six months in two of the studies. Five studies compared mannitol with control (a very low dose of mannitol or non-respirable mannitol) and the final study compared mannitol to dornase alfa alone and to mannitol plus dornase alfa. Two large studies had a similar parallel design and provided data for 600 participants, which could be pooled where data for a particular outcome and time point were

    It is generally believed that patients with Hürthle cell thyroid carcinoma (HCTC) have a poor prognosis. Furthermore, distant metastases represent the most frequent cause of thyroid cancer-related death of patients with HCTC. The aim of this study was to report the treatment and outcomes of patients with distant metastases. Altogether 108 patients were treated for HCTC from 1972 to 2011 in our tertiary center and 32 patients (19 females, 13 males; median age 64.5 years) had either initially proven metastatic disease (N = 12) or distant progression of HCTC after initial treatment (N = 20). Patients with metastases were followed for 1–226 (median 77) months. Data were collected on the patients’ gender and age, extent of their disease, morphologic characteristics, therapy, outcome, and survival rate. Statistical correlation between possible prognostic factors and cause-specific survival from time of detection of metastases was analyzed by univariate analysis and log-rank test. The most common were lung metastases, followed by bone, mediastinum, kidney, and liver in 24, 8, 2, 1, and 1 case, respectively. Total thyroidectomy, lobectomy, subtotal thyroidectomy and neck dissection were performed in 19, 10, 3, and 7 patients, respectively. Radioiodine (RAI) ablation of thyroid remnant was performed in 30 patients, while 20 of them had RAI therapy (median 4 times). RAI uptake in metastases was present in 16 patients and ranged from 0.05 % to 12 %. Chemotherapy was used in 13 patients and external beam radiotherapy in 19 patients. Locoregional control of disease was achieved in 19/21 (90 %) cases who succumbed due to HCTC. Estimated 10-year disease-specific survival for all patients was 60 %. 10-year disease-specific survival for patients with pulmonary metastases and other sites metastases was 60 % and 62 %, respectively. 10-year disease-specific survival for patients with single organ and multiple organ metastases was 52 %, and 100 %, respectively. Estimated median

    We examined the roles of Ultrasonography conductors by analyzing the results of tissue biopsy of complex cystic masse under the guidance of breast US. This study was performed to a group of 178 who showed breast US indicating complex cystic masses among 342 patients who were definitely diagnosed by tissue biopsies and operations in our hospital from June 30th, 2003 to June 30th, 2007. The evaluation of tissues around, calcification, the distribution state of blood flow were excluded from the analysis subjects and logic 200 made by GE corporation and gun for core biopsy(Kimal corp., K7/MBD23) were used in this study. The biopsy results of 178 subjects showed FCC (fibrocystic change)(n=56 : 31.4%), Fibrosis (n=41 : 23.0%), Fibroadenoma (n=20 : 11.2%), Epithelial hyperplasia (n=17 : 9.6%), Carcinoma (n=15 : 8.4%), Fibroadipose (n=8 : 4.5%), Sclerosing adenosis (n=7 : 3.9%), Duct ectasia (n=5 : 2.8%), Papiloma (n=5 : 2.8%), and Fat necrosis (n=1 : 0.6%), Hemangioma (n=1 : 0.6%), Abscess (n=1 : 0.6%), Dystrophic calcification(n=1 : 0.6%). The US showed that the results of the tissue biopsy of complex cystic masses were mostly carcinoma(8.4%). Most of them were benign and only 9.6% of epithelial hyperplasia which has high progression rate into malignant tumors epidemically showed malignancy. Most of them were included in the spectrum of fibrous cystic nodule. Even though these results are confirmed, further studies are required. As a result, a nodule which is not certified by US should be right to take the tissue biopsy, but if it's difficult due to patients or another reasons, re-check tests in three months are required. And systemic ultrasonography evaluation should be well recognized to conduct more careful and specific tests.

    Parathyroid carcinoma (PC) is a very rare endocrine tumour, usually characterized by symptoms such as a neck mass, dysphonia, severe hypercalcemia exceeding 140 mg/L and elevated serum parathyroid hormone levels, even more than 5 times the upper limit of normal. Non-functioning parathyroid cancer is extremely rare and, in this case, its pre-operative diagnosis is often difficult. A 54-year old female patient, referring dysphagia and dysphonia, underwent neck ultrasound and neck CT. A left thyroid nodule, probably cystic, was found. It presented caudal extent on anterior mediastinum causing compression of the left lateral wall of the trachea. The preoperative calcemia was into the normal range. The patient underwent left thyroid lobectomy. Histological exam showed a cystic lesion, immunohistochemically originating from parathyroid that oriented for carcinoma. The 18 months follow-up did not show a residual-recurrent disease. The parathyroid origin of a neck lesion could not be suspected before surgery when specific laboratory tests are not available and clinical effects of hyperparathyroidism syndrome are not present. Histological features are not always sufficient for the differential diagnosis between the parathyroid adenoma and carcinoma. The immunohistochemistry is an useful tool that can aid to reach the definite diagnosis.

    Objective: To evaluate real-time qualitative ultrasound elastography for focal thyroid masses undergoing fine-needle aspiration in a routine thyroid ultrasound clinic. Materials and methods: Ninety-four thyroid nodules scheduled for fine-needle aspiration cytology in a thyroid ultrasound clinic also underwent real-time freehand elastography. Colour-scaled elastograms were graded visually on the stiffness of the solid component of nodules relative to thyroid parenchyma using an elastography score (ES) scale from 1 (soft) to 4 (stiff). The ES for benign and malignant nodules and the influence of cystic change on ES were analysed using Chi-square with trend and Fishers exact tests, with a p < 0.05 used to indicate statistical significance. Results: There were 19 papillary carcinomas, five metastases, 57 hyperplastic nodules, and four follicular adenomas based on definitive cytology (n = 54) or histology (n = 31). Nine nodules were excluded due to indeterminate cytology and no histology. Of malignancies (all solid), two were ES = 1, four were ES = 2, eight were ES = 3, and 10 were ES = 4. Of benign nodules, 17 were ES = 1, 17 were ES = 2, 16 were ES = 3, and 11 were ES = 4. An ES > 2 was more common in benign nodules with predominant cystic components (17/18) than mildly cystic (3/12) or completely solid (7/31) benign nodules (p = 0.0004, p < 0.0001). The ES was not significantly different between benign and malignant nodules (p = 0.09) unless partially cystic nodules were excluded (p = 0.005). For solid nodules, an ES > 2 optimally predicted malignancy, achieving 74% sensitivity, 77% specificity, and 76% accuracy. Conclusion: Qualitative real-time thyroid elastography predicts malignancy only if predominantly cystic nodules are excluded, which may limit its utility in routine clinical practice.

  11. Pyelo-cystic Reflux in F-18 FDG PET Scan Due to Ureteral Obstruction

    2013-09-15

    A 72-year-old woman with a history of cervical cancer was treated with brachytherapy and chemotherapy. Combined F-18 FDG PET/CT performed for restaging demonstrated increased FDG uptake in a hypodense cystic lesion at the posterior part of the right renal cortex and a hypermetabolic soft tissue mass at the right parailiac region suggestive of a metastatic lymph node causing ureteral obstruction. There had been no FDG uptake in the cystic lesion on the FDG PET/CT study performed 1 year before. These findings suggest that the increased FDG uptake in the cystic lesion was caused by pyelocystic reflux due to ureteral obstruction secondary to parailiac lymph node metastasis (Figs. 1 and 2). Several renal lesions may have increased metabolism, such as renal cell carcinoma, lymphoma, oncocytoma, adult Wilms' tumor, angiomyolipoma, metastatic lesions, xanthogranulo-matous pyelonephritis and infected cyst. Most of these lesions are solid. Some infected renal cysts may be FDG avid, but in this situation increased FDG uptake is observed on the wall of the cyst. In our case, FDG uptake was seen in the entire cystic lesion. The patient had no symptoms or laboratory findings related to infection. Cysts are the most common space-occupying lesions of the kidney. The vast majority of these are simple cysts that are usually unilateral and solitary. Simple cysts are asymptomatic, except when complications exist such as hemorrhage, infection or rupture. There have been a few reports on spontaneous communications between renal cysts and the pyelocaliceal system, in most cases involving ruptures of the cysts into the pyelocaliceal system due to increased intracystic pressure caused by bleeding or infection of the cyst. In the present case, the cause of the connection between the cystic cavity and the pyelocaliceal system is the increased pressure in the renal pelvic cavity due to the ureteral obstruction secondary to parailiac lymph node metastasis.

    A 48-year-old man presented with a 3-month history of weight loss and progressive right lower quadrant abdominal pain. His medical history was notable for appendectomy at age 17. Ultrasonography and computed tomography of the abdomen revealed a 12 cm multicystic mass in the right paracolic space. At laparotomy a large serous cyst was found arising from the lateral wall of the cecum, and four additional small cysts were found on the small bowel mesentery, greater omentum, liver capsule, and right hemi-diaphragm. Complete removal of the tumor was accomplished by right colectomy with extraperitoneal dissection of the large cyst and simple excision of the four smaller cysts. Final pathology with immunohistochemical staining confirmed cystic mesothelioma of the peritoneum. In this report we discuss the diagnostic workup and treatment of this rare disease.

    Full Text Available Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts, the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

    Children with cystic fibrosis liver disease and portal hypertension are at risk of developing acute hepatic encephalopathy. Even in the presence of normal synthetic liver function these children may have porto-systemic shunting. We report a case of an adolosecent who had cystic fibrosis liver disease and presented with life threatening hepatinc encephalopathy. This case illustrates that it is necessary to consider an appropriate dietary regimen in adolosecents with liver disease to prevent hepatic decompensation. Copyright © 2012 Wiley Periodicals, Inc.

    The congenital cystic adenomatoid malformation (CCAM) of the newborn is a particular form among the cystic disorders of the lung. The clinical findings, illustrated by four cases, and especially the roentgenographic symptoms are typical. Different radiologic examinations, including the computertomography, are discussed. The differential diagnosis of the disease is various, and therefore a correct and on time diagnosis is necessary, because the prognosis of the patient depends on an adequate therapy. (orig.) [de

    Lower lip squamous cell carcinoma (LLSCC) is a common malignancy of the head and neck, being mainly a consequence of a chronic exposure to ultraviolet (UV) light solar radiation. Here, we evaluated the clinicopathological profile of patients with photosensitive disorders (xeroderma pigmentosum, lupus erythematosus and albinism) that developed LLSCC. Data from patients who had a diagnosed LLSCC with a prior xeroderma pigmentosum, lupus erythematosus or albinism diagnosis that were treated at INCA from 1999 to 2012 were collected from patients medical records (n=16). The control group was composed of 68 patients with LLSCC without a medical history of photosensitivity. The clinicopathological data of this study population were collected and the association between these variables was analyzed by Fisher's exact test. Survival curves were constructed using the Kaplan-Meier method and compared by log-rank test. All statistical analyses were performed using SPSS statistics package. The mean age of patients in the photosensitive and non-photosensitive groups was 42 years and 67 years, respectively (p<0.0001). A previous history of malignant diseases was more common in the photosensitive group (p=0.001). In both groups, most tumors showed a pathological stage I/II disease. Overall and cancer-specific survival were not statistically different. However, disease-free interval showed a significant difference (p=0.01) between the photosensitive and non-photosensitive patients. Photosensitive patients presented LLSCC at earlier age but it usually was not the primary tumor in these patients. Furthermore, a more aggressive pathological behavior was not seen when compared with tumors from non-photosensitive patients. The disease-free interval was lower in photosensitive patients, as expected.

    Purpose: To evaluate the CT findings of skeletal cystic echinococcosis. Material and Methods: CT findings of 7 patients with pathologically confirmed skeletal cystic echinococcosis were evaluated. Results: There were 4 men and 3 women, aged 36-75 years. Hydatid cysts were located in the spine (n=2), a rib (n=3), the pelvis and a vertebra (n=1), the pelvis and the left femur (n=1). The size of the lesions varied from 1 cm to 15 cm. CT showed well defined, single or multiple cystic lesions with no contrast enhancement, no calcification, no daughter cysts, and no germinal membrane detachment. The cystic lesion had a honeycomb appearance in 2 cases, there was pathologic fracture in 2 cases, bone expansion in 5 cases, cortical thinning in 6 cases, cortical destruction in 6 cases, bone sclerosis in 1 case, and soft tissue extension in 6 cases. Conclusion: Preoperative differential diagnosis of skeletal cystic lesions should include cystic echinococcosis, especially in endemic areas, since this diagnosis may easily be missed unless kept in mind.

    1987-01-01

    Renal cystic disease includes a group of lesions with extremely diverse clinical, radiographic, and pathologic findings. The recent development of multiple imaging systems to study renal cystic disease has resulted in considerable interest in correlating the images obtained by different modalities with each other and with the underlying gross pathology. A thorough knowledge of the disturbed morphology and natural history of these diseases will lead to a better understanding of their appearance on radiologic imaging. This refresher course correlates disturbed morphology with appearances on diagnostic imaging, urography, US, angiography, CT, and MR imaging. The advantages and limitations of each imaging method are detailed. A practical classification emphasizing differential features is presented. The presentation is divided into two parts. In the first part typical and atypical cystic masses, including acquired cystic disease (from dialysis), Von Hippel-Lindau disease, and the cystic disease of tuberous sclerosis are discussed. In the second part, polycystic kidney disease (dominant and recessive), medullary cystic disease, medullary sponge kidney, multicycle-dysplastic kidney, renal sinus cysts (peripelvic), and pluricystic kidney disease are discussed

    Full Text Available Cystic trophoblastic tumor (CTT is a rare testicular germ cell tumor (GCT predominantly seen in post-chemotherapy patients. It is prognostically similar to teratoma and requires no additional chemotherapy in the absence of a nonteratomatous GCT component. We report a case of metastatic CTT in a patient with primary testicular teratoma without prior chemotherapy. Retroperitoneal lymph node metastases contained teratoma, embryonal carcinoma, and CTT. The CTT was β-hCG positive and SALL4 negative by immunohistochemistry (IHC. CTT can arise in metastatic testicular GCT in treatment naïve patients. An important differential diagnosis is choriocarcinoma due to treatment implications, and SALL4 IHC may help.

    2013-07-01

    Low-grade salivary duct carcinoma (LG-SDC) is a rare neoplasm characterized by predominant intraductal growth, luminal ductal phenotype, bland microscopic features, and favorable clinical behavior with an appearance reminiscent of florid to atypical ductal hyperplasia to low grade intraductal breast carcinoma. LG-SDC is composed of multiple cysts, cribriform architecture with "Roman Bridges", "pseudocribriform" proliferations with floppy fenestrations or irregular slits, micropapillae with epithelial tufts, fibrovascular cores, and solid areas. Most of the tumor cells are small to medium sized with pale eosinophilic cytoplasm, and round to oval nuclei, which may contain finely dispersed or dark condensed chromatin. Foci of intermediate to high grade atypia, and invasive carcinoma or micro-invasion have been reported in up to 23 % of cases. The neoplastic cells have a ductal phenotype with coexpression of keratins and S100 protein and are surrounded by a layer of myoepithelial cells in non-invasive cases. The main differential diagnosis of LG-SDC includes cystadenoma, cystadenocarcinoma, sclerosing polycystic adenosis, salivary duct carcinoma in situ/high-grade intraductal carcinoma, and papillary-cystic variant of acinic cell carcinoma. There is no published data supporting the continuous classification of LG-SDC as a variant of cystadenocarcinoma. Given that most LG-SDC are non-invasive neoplasms; the terms "cribriform cystadenocarcinoma" and LG-SDC should be replaced by "low-grade intraductal carcinoma" (LG-IDC) of salivary gland or "low-grade intraductal carcinoma with areas of invasive carcinoma" in those cases with evidence of invasive carcinoma.

    Yttrium-90 transarterial radioembolization (TARE) is a locoregional therapy (LRT) for hepatocellular carcinoma (HCC). In this study, we present overall survival (OS) outcomes in a 1,000-patient cohort acquired over a 15-year period. Between December 1, 2003 and March 31, 2017, 1,000 patients with HCC were treated with TARE as part of a prospective cohort study. A comprehensive review of toxicity and survival outcomes was performed. Outcomes were stratified by baseline Child-Pugh (CP) class, United Network for Organ Sharing (UNOS), and Barcelona Clinic Liver Cancer (BCLC) staging systems. Albumin and bilirubin laboratory toxicities were compared to baseline. OS outcomes were reported using censoring and intention-to-treat methodologies. All treatments were outpatient, with a median one treatment per patient. Five hundred six (51%) were CP A, 450 (45%) CP B, and 44 (4%) CP C. Two hundred sixty-three (26%) patients were BCLC A, 152 (15%) B, 541 (54%) C, and 44 (4%) D. Three hundred sixty-eight (37%) were UNOS T1/T2, 169 (17%) T3, 147 (15%) T4a, 223 (22%) T4b, and 93 (9%) N/M. In CP A patients, censored OS for BCLC A was 47.3 (confidence interval [CI], 39.5-80.3) months, BCLC B 25.0 (CI, 17.3-30.5) months, and BCLC C 15.0 (CI, 13.8-17.7) months. In CP B patients, censored OS for BCLC A was 27 (CI, 21-30.2) months, BCLC B 15.0 (CI, 12.3-19.0) months, and BCLC C 8.0 (CI, 6.8-9.5) months. Forty-nine (5%) and 110 (11%) patients developed grade 3/4 albumin and bilirubin toxicities, respectively. Based on our experience with 1,000 patients over 15 years, we have made a decision to adopt TARE as the first-line transarterial LRT for patients with HCC. Our decision was informed by prospective data and incrementally reported demonstrating outcomes stratified by BCLC, applied as either neoadjuvant or definitive treatment.

    Theoretically, cystic fibrosis transmembrane conductance regulator (CFTR) gene replacement during the neonatal period can decrease morbidity and mortality from cystic fibrosis (CF). In vivo gene transfers have been accomplished in CF patients. Choice of vector, mode of delivery to airways, translocation of genetic information, and sufficient expression level of the normalized CFTR gene are issues that currently are being addressed in the field. The advantages and limitations of viral vectors are a function of the parent virus. Viral vectors used in this setting include adenovirus (Ad) and adeno-associated virus (AAV). Initial studies with Ad vectors resulted in a vector that was efficient for gene transfer with dose-limiting inflammatory effects due to the large amount of viral protein delivered. The next generation of Ad vectors, with more viral coding sequence deletions, has a longer duration of activity and elicits a lesser degree of cell-mediated immunity in mice. A more recent generation of Ad vectors has no viral genes remaining. Despite these changes, the problem of humoral immunity remains with Ad vectors. A variety of strategies such as vector systems requiring single, or widely spaced, administrations, pharmacologic immunosuppression at administration, creation of a stealth vector, modification of immunogenic epitopes, or tolerance induction are being considered to circumvent humoral immunity. AAV vectors have been studied in animal and human models. They do not appear to induce inflammatory changes over a wide range of doses. The level of CFTR messenger RNA expression is difficult to ascertain with AAV vectors since the small size of the vector relative to the CFTR gene leaves no space for vector-specific sequences on which to base assays to distinguish endogenous from vector-expressed messenger RNA. In general, AAV vectors appear to be safe and have superior duration profiles. Cationic liposomes are lipid-DNA complexes. These vectors generally have been

    We investigated the ultrasonographic (US) appearance of metapIastic squamous breast carcinoma with the pathologic correlation. During an 8-year period, the US appearances of 10 patients with metaplastic squamous breast carcinoma were retrospectively analyzed on the basis of the Breast Imaging and Reporting Data System (BI-RADS) - US lexicon. These 10 patients included 9 patients having invasive adenocarcinomas of the breast with more than 30% squamous metaplasia, and one patient had pure primary squamous cell carcinoma. We correlated the US findings with the pathologic findings. On US, the majority of the tumors showed ovaI shapes (70%), indistinct margins (50%), parallel orientation (80%), echogenic halos (60%), complex echogenicity with solid and cystic components (60%), and posterior enhancement (70%). The findings of calcifications (20%) and metastatic axillary lymph nodes (10%) were rare. On pathologic examination, half of the tumors showed infiltrative microscopic margins. All six cases showing complex echogenicity with solid and cystic components on US were pathologically related to the cystic or necrotic portion, and three of these cases had hemorrhage. On US, metapIastic squamous breast carcinoma mainly manifested as oval, complex, echoic masses with indistinct margins and posterior enhancement that was pathologically related to the cystic or necrotic portions

    Purpose: The Dutch Head and Neck Oncology Cooperative Group, in which head and neck groups of all University hospitals and the two cancer institutes are represented, initiated a retrospective study concerning salivary gland carcinomas. A majority of Dutch patients with head and neck carcinomas are treated in the participating centres, and the follow-up is precise. Prognostic factors for local control and survival were studied, with special interest in the role of treatment and the role of histologic type. Methods and materials: Results were obtained of 568 patients with a mean follow-up time of 5 years. The parotid gland was involved in 59%, the submandibular gland in 14%, oral cavity in 24% and 3% was located elsewhere. Mean age was 59 years (range 8-100 yr), 48% was female. T-stage was T 1 in 27%, T 2 in 44%, T 3 in 19% and T 4 in 11%. Positive necknodes were seen in 15%, 3% was initially M 1 . Histologic type was acinic cell carcinoma in 12%, mucoepidermoid ca. in 16%, adenoid cystic ca. in 26%, adenoca. in 24%, carcinoma in pleomorphic adenoma in 8%, squamous cell ca. in 6% and undifferentiated ca. in 7%. Resection margins were radical in 37%, close in 20% and irradical in 40% (3% unknown). Surgery was the primary treatment in 501 patients, combined with postoperative radiotherapy (50-70 Gy, mean dose 62 Gy) in 389 patients. Radiotherapy was the primary treatment in 40 patients (18 M 1 , 30% N+), 20 patients were not treated and 7 patients were treated otherwise. For statistical analysis the Cox PH regression analysis was used (SPSS-PC+). Results: Actuarial local control after 8 years was 80% for surgery alone and 92% for the combined modality (in which more advanced cases prevaled). Independent factors for local control in the surgery±radiotherapy group were: I:T-stage (T 3 vs T 1-2 : RR 3.7; T 4 vs T 1-2 : RR 11.7), II: anatomic site (oral cavity vs parotid and submandibular gland: RR 0.2) and III: treatment modality (surgery alone vs surgery

    Shared Pathology Informatics Network (SPIN) is a tissue resource initiative that utilizes clinical reports of the vast amount of paraffin-embedded tissues routinely stored by medical centers. SPIN has an informatics component (sending tissue-related queries to multiple institutions via the internet) and a service component (providing histopathologically annotated tissue specimens for medical research). This paper examines if tissue blocks, identified by localized computer searches at participating institutions, can be retrieved in adequate quantity and quality to support medical researchers. Four centers evaluated pathology reports (1990–2005) for common and rare tumors to determine the percentage of cases where suitable tissue blocks with tumor were available. Each site generated a list of 100 common tumor cases (25 cases each of breast adenocarcinoma, colonic adenocarcinoma, lung squamous carcinoma, and prostate adenocarcinoma) and 100 rare tumor cases (25 cases each of adrenal cortical carcinoma, gastro-intestinal stromal tumor [GIST], adenoid cystic carcinoma, and mycosis fungoides) using a combination of Tumor Registry, laboratory information system (LIS) and/or SPIN-related tools. Pathologists identified the slides/blocks with tumor and noted first 3 slides with largest tumor and availability of the corresponding block. Common tumors cases (n = 400), the institutional retrieval rates (all blocks) were 83% (A), 95% (B), 80% (C), and 98% (D). Retrieval rate (tumor blocks) from all centers for common tumors was 73% with mean largest tumor size of 1.49 cm; retrieval (tumor blocks) was highest-lung (84%) and lowest-prostate (54%). Rare tumors cases (n = 400), each institution's retrieval rates (all blocks) were 78% (A), 73% (B), 67% (C), and 84% (D). Retrieval rate (tumor blocks) from all centers for rare tumors was 66% with mean largest tumor size of 1.56 cm; retrieval (tumor blocks) was highest for GIST (72%) and lowest for adenoid cystic carcinoma (58

    Infertility rates among males with cystic fibrosis (CF) approximate 97%. No information is currently available within Ireland determining an understanding of fertility issues and the best methods of information provision to this specialized group. This study aimed to determine understanding and preferred approaches to information provision on fertility issues to Irish CF males. A Descriptive Study utilizing prospective coded questionnaires was mailed to a male CF cohort (n=50). Sections included demographics, fertility knowledge & investigation. Response rate was 16\\/50 (32%). All were aware that CF affected their fertility. More than two-thirds (n=11) were able to provide explanations whilst only one-third (n=5) provided the correct explanation. Significant numbers stated thoughts of marriage and a future family. Half have discussed fertility with a healthcare professional (HCP). Mean age of discussion was 21.9 years. One third preferred an earlier discussion. The commonest first source for information was written material which was also the preferred source. Three-quarters requested further information preferring again, written material. Significant gaps in sex education of Irish CF males exist. Discussion should be initiated by HCPs and centre-directed written material devised to address deficiencies.

    Full Text Available AbstractIntroduction: Craniopharyngioma of childhood are commonly cystic in nature. An intracystic catheter insertion and subsequent instillation of substances inducing cyst shrinkage seems a beneficial strategy avoiding additional morbidity in a highly vulnerable brain location. Methods: A systematic review of the medical literature was performed to identify potentially relevant, all languages articles using Ovid MEDLINE and EMBASE from inception to July 2011 and Cochrane Central Register of Controlled Trials to 3rd quarter 2011. All references were examined for relevancy. Results: Of 142 unique references x referred to substances used for intracystic craniopharyngioma treatment. General aspects of intracystic catheter insertion as well as response rates, risks and outcomes of children treated with intracystic radio-isotopes, bleomycin and interferon are critically reviewed and an outline for potential future endeavours provided. Conclusions: Interferon seems currently the intracystic substance with the best benefit risk ratio. The authors advocate for consensus on prospective data collection and standardized intracystic treatment strategies to allow reliable comparisons and herewith optimize treatment and outcome.

  16. Cystic fibrosis: a clinical view.

    Cystic fibrosis (CF), a monogenic disease caused by mutations in the CFTR gene on chromosome 7, is complex and greatly variable in clinical expression. Airways, pancreas, male genital system, intestine, liver, bone, and kidney are involved. The lack of CFTR or its impaired function causes fat malabsorption and chronic pulmonary infections leading to bronchiectasis and progressive lung damage. Previously considered lethal in infancy and childhood, CF has now attained median survivals of 50 years of age, mainly thanks to the early diagnosis through neonatal screening, recognition of mild forms, and an aggressive therapeutic attitude. Classical treatment includes pancreatic enzyme replacement, respiratory physiotherapy, mucolitics, and aggressive antibiotic therapy. A significant proportion of patients with severe symptoms still requires lung or, less frequently, liver transplantation. The great number of mutations and their diverse effects on the CFTR protein account only partially for CF clinical variability, and modifier genes have a role in modulating the clinical expression of the disease. Despite the increasing understanding of CFTR functioning, several aspects of CF need still to be clarified, e.g., the worse outcome in females, the risk of malignancies, the pathophysiology, and best treatment of comorbidities, such as CF-related diabetes or CF-related bone disorder. Research is focusing on new drugs restoring CFTR function, some already available and with good clinical impact, others showing promising preliminary results that need to be confirmed in phase III clinical trials.

    Parathyroid adenoma with cystic degeneration is a rare cause of primary hyperparathyroidism. The clinical and biochemical presentation may mimic parathyroid carcinoma. We report the case of a 55 year old lady, who had longstanding history of depression and acid peptic disease. Serum calcium eight months prior to presentation was slightly high, but she was never worked up. She was found to be Vitamin D deficient while being investigated for generalized body aches. A month after she was replaced with Vitamin D, she presented to us with parathyroid crisis. Her corrected serum calcium was 23.0 mg/dL. She had severe gastrointestinal symptoms and acute kidney injury. She had unexplained consistent hypokalemia until surgery. Neck ultrasound and CT scan revealed giant parathyroid cyst extending into the mediastinum. After initial medical management for parathyroid crisis, parathyroid cystic adenoma was surgically excised. Her serum calcium, intact parathyroid hormone, creatinine and potassium levels normalized after surgery. This case of parathyroid crisis, with very high serum calcium and parathyroid hormone levels, is a rare presentation of parathyroid adenoma with cystic degeneration. This case also highlights that Vitamin D replacement may unmask subclinical hyperparathyroidism. Consistent hypokalemia until surgery merits research into its association with hypercalcemia.

    To investigate the feasibility of magnetization transfer contrast (MTC) in characterization of pelvic cystic masses and ascites, in vitro studies were performed. Cystic fluids were taken from operative specimens of ten ovarian cystic masses (five mucinous cystadenomas, one cystadenocarcinoma, two serous cystadenocarcinomas, two clear cell carcinomas) and three non-ovarian pelvic cysts (one paraovarian cyst, one pseudomyxoma peritonei, one pelvic abscess). Samples of ascitic flied were drawn by peritoneal puncture in twenty patients (thirteen with peritonitis carcinomatosa, five with liver dysfunction, two with renal dysfunction). Total protein content in ascitic fluids was measured. Magnetization transfer ratio (MTR) was calculated by the signal intensities under the gradient echo sequence with and without the application of off-resonance pulses. The relative signal intensities (RSI) relative to water in T{sub 1} and T{sub 2} weighted images were obtained using spin echo sequence. There was no correlation between histological type of pelvic mass and MTR and RSI. Good correlation (R{sup 2}=0.761) was obtained between MTR and protein content in ascitic fluids, whereas no correlation was noted between RSI and protein content in ascitic fluids. These results suggest that MTC is not useful in the characterization of pelvic masses but is applicable in the differentiation between exudative ascites and transudative ascites. (author)

    The intracystic papillary carcinoma is a rare form of mamma cancer, with an incidence of 0.5-1 % of all mamma cancers. It is a tumor predominantly affecting women in advanced age. Although it was believed that this rare entity was a variant of ductal carcinoma in situ, some lesions might be tumors of low risk invasiveness. The tumor has an excellent prognosis despite being in situ or invasive one. Therefore, the precise diagnosis plays an important role in the management of patients with this entity. We report the case of an intracystic papillary carcinoma in a woman aged 75 years. Among other pathological findings, the tumor was 2 cm and was located in the low external quadrant of the right mamma. In the carried out ultrasonography, it was informed an echo lucid image, of well defined edges, and the mammography showed the presence of a nodular image with irregular edges. The histopathologic diagnosis was non-invasive papillary carcinoma, inside a 1 cm cystic lesion, with an 0,5 cm solid nodule inside of low nuclear grade. A wide tumorectomy was carried out. Currently it is controlled. For the elaboration of the current paper we consulted 17 materials of journals and Surgery textbooks. The aim was reporting an intracystic papillary carcinoma case, showing how rare this pathology is for the specialists on the theme. (author)

    Thyroid carcinoma (TC) is a slow growing tumor with an indolent course and has an excellent prognosis. However, a sharp contrast exists in the biological behavior of TC, which in its well-differentiated form is associated with long-term survival, but in its undifferentiated form is one of the most lethal neoplasms known. The anaplastic carcinoma (ANC) form has a fulminanat course with poor prognosis and almost invariably, a fatal outcome

    To determine the effects of respiration on the size of lung cysts by comparing inspiratory and expiratory high-resolution CT (HRCT) scans. The authors evaluated the size of cystic lesions, as seen on paired inspiratory and expiratory HRCT scans, in 54 patients with Langerhans cell histiocytosis (n = 3), pulmonary lymphangiomyomatosis (n = 4), confluent centrilobular emphysema (n = 9), paraseptal emphysema and bullae (n = 16), cystic bronchiectasis (n = 13), and honeycombing (n = 9). Using paired inspiratory and expiratory HRCT scans obtained at the corresponding anatomic level, a total of 270 cystic lesions were selected simultaneously on the basis of five lesions per lung disease. Changes in lung cyst size observed during respiration were assessed by two radiologists. In a limited number of cases (n = 11), pathologic specimens were obtained by open lung biopsy or lobectomy. All cystic lesions in patients with Langerhans cell histiocytosis, lymphangiomyomatosis, cystic bronchiectasis, honeycombing, and confluent centrilobular emphysema became smaller on expiration, but in two cases of paraseptal emphysema and bullae there was no change. In cases in which expiratory CT scans indicate that cysts have become smaller, cystic lesions may communicate with the airways. To determine whether, for cysts and cystic lesions, this connection does in fact exist, paired inspiratory and expiratory HRCT scans are necessary

    To determine the frequency and profile of carcinoma in multi-nodular goiter and solitary thyroid nodule. Study Design: Case series. Place and Duration of Study: Surgical Unit-I, Ward-3 of Jinnah Postgraduate Medical Centre, Karachi, from January 1999 to January 2009. Methodology: Cases with solitary thyroid nodules and multi-nodular goiter were included. Patients under 12 years of age, cystic benign lesion in solitary thyroid nodules or those multi-nodular goiters which were not causing pressure symptoms, cosmetic problems or sign of malignancy were excluded. In solitary thyroid nodule, hemithyroidectomy was done and if histopathology examination revealed carcinoma thyroid then completion thyroidectomy was done. In multi-nodular goiter sub-total thyroidectomy done. Results were described as frequency percentages and mean. Results: Out of 397 patients of multi-nodular goiter only one patient was found to be papillary carcinoma (0.25%). In 220 patients of solitary thyroid nodules, 93 patients were diagnosed as carcinoma of thyroid (42.27%). Others diagnosed in solitary thyroid nodule were thyroid adenoma, colloid goiter, thyroiditis and multi-nodular goiter. The frequency of papillary carcinoma in 65.95% occurring females of 12-30 years of age and being multifocal in 6.45%, follicular carcinoma in 23.40%, medullary carcinoma in 7.44%, anaplastic carcinoma in 2.12% and lymphoma in 1.01%. Female were predominantly involved and papillary carcinoma was common in 12-30 years of age (71.63%) and follicular was common in 30-40 years of age (68.18%). 6.45% of papillary carcinoma was found to be multifocal in nature. Conclusion: Frequency of carcinoma of thyroid is very high in solitary thyroid nodule (42.27%), but markedly low in multi nodular goiter. Papillary carcinoma is the most common variety, most of in younger female. (author)

    The prognosis of locally advanced cervix cancers is poor with metastatic and local recurrence risks. Recent publications reported that concurrent chemotherapy and pelvic radiation increased local control compared to radiotherapy alone. Chemotherapy could also decrease metastatic recurrences. We report 92 cases of patients with locally advanced cervix cancer treated between 1986 and 1998 at the Institut Curie. Patients and methods. - Concurrent chemo-radiation was exclusive in 51 cases and added to surgery in 41 cases. Chemotherapy with 5FU -Cisplatin-Mitomycin C-Vindesin (protocol A) was performed for 43% of patients and 57% of them received 5FU-Cisplatin alone (protocol B). Results. -Median follow-up was 64 months (6-149 months). Five-year disease-free survival rate was 47% and local control rate was 70%. Disease-free survival was correlated with therapeutic response. After exclusive chemo-radiation, the good responsive patients had a better DFS (54% vs 26%, p=0.018). In the surgery group, those patients with sterilized lymph nodes and tumours had also a higher DFS (76% vs 47%, p=0.036). Toxicity was higher with protocol A. Conclusion. - From our study, it appears that local control of advanced cervix cancers is better with combined chemoradiotherapy but disease-free survival stays low according to the metastatic evolution. Metastasis without local recurrence remained frequent in our study. 5FU-CDDP chemotherapy has a lower toxicity and is as effective as 5FU-CDDP-Mitomycin C-Vindesin protocol, in association with radiotherapy.

    Full Text Available The calcifying cystic odontogenic tumor normally presents as apainless, slow-growing mass, involving both maxilla and mandible,primarily the anterior segment (incisor/canine area. It generallyaffects young adults in the third to fourth decades, with no genderpredilection. Computerized tomography images revealed importantcharacteristics that were not detected by panoramic radiography,such as fenestration, calcification and tooth-like structures. Thetypical microscopic feature of this lesion is the presence of variableamounts of aberrant epithelial cells, without nuclei, which arenamed “ghost cells”. In addition, dysplastic dentine can be foundand occasionally the cyst can be associated with an area of dentalhard tissue formation resembling an odontoma. The treatment forcalcifying cystic odontogenic tumor involves simple enucleationand curettage. The purpose of this article is to present two differentmanifestation of calcifying cystic odontogenic tumor in whichcomputerized tomography, associated to clinical features, servedas an important tool for diagnosis, adequate surgical planning andfollow-up of patients.

    A cystic lesion in the lung is defined as a well-demarcated epithel-lined cavity, that can be mostly filled with air, water, as well as solid material content. This definition includes a wide variety of diseases such as bronchogenic cyst, abscess formation, lymphangioleiomyomatosis, Langerhans cell histiocytosis, emphysema, bronchiectasis, and pneumatoceles. Despite the difficulties in differential diagnosis, there are some diagnostic criteria for CT-scanning helping the radiologist to differentiate between these cystic entities. Moreover, clinical informations are extremely important. The most important clinical parameters include age, sex, clinical history and symptoms. Thus, a better understanding of classic CT appearance of cystic lung disease will allow more definitive diagnosis and could, in some cases, avoid biopsy. (orig.)

    We retrospectively analysed CT findings of 47 cystic brain lesions of 44 patients, in which operation, biopsy or follow-up study was needed for their final diagnosis. The results were as follows: 1. The etiologic diseases of cystic brain lesions were 15 cases of brain abscess, 9 cases of astrocytoma, 5 cases of glioblastoma multiforme, 3 cases of meningioma, 5 cases of craniopharyngioma, 1 case of hemangioblastoma, 2 cases of dermoid cyst and 4 cases of metastasis. 2. We analyses the cystic lesions in view of their number, location, shape, perifocal edema, mass effect, wall and its thickness, evenness and characteristics of their inner and outer surfaces, mural nodule, calcification and contrast enhancement. a. 13.3% of brain abscess and 75% of metastases were multiple in number, but the remainder showed single lesion. b. The shape of cystic lesions were round or ovoid in 68%, lobulated in 8.5% and irregular in 23.5%, and no demonstrable difference of shape were noticed in different disease. c. In brain abscess, the wall of cystic lesions tend to be thin, even and smooth in inner surface, but the outer surfaces were equally smooth or irregular. d. Mural nodules were found in nearly half of the cases of astrocytoma, glioblastoma multiforme, metastasis and hemangioblastoma, but the brain abscess and dermoid cyst contained no mural nodule. e. Meningiomas were found to be attached to dura mater and showed thickening of the inner table of adjacent skull or of the falx. f. The presence of preceding infectious disease may be helpful in the diagnosis of brain abscess, but in 20% there were no demonstrable preceding infection. g. Lung cancer was confirmed as primary site in two of the cystic metastatic disease, but other 2 cases showed no demonstrable primary malignancy

    Context Cystic fibrosis (CF) is the most widespread autosomal recessive genetic disorder that limits life expectation amongst the Caucasian population. As the median survival has increased related to early multidisciplinary intervention, other manifestations of CF have emergedespecially for the broad spectrum of hepatobiliary involvement. The present study reviews the existing literature on liver disease in cystic fibrosis and describes the key issues for an adequate clinical evaluation and management of patients, with a focus on the pathogenetic, clinical and diagnostic-therapeutic aspects of liver disease in CF. Evidence Acquisition A literature search of electronic databases was undertaken for relevant studies published from 1990 about liver disease in cystic fibrosis. The databases searched were: EMBASE, PubMed and Cochrane Library. Results CF is due to mutations in the gene on chromosome 7 that encodes an amino acidic polypeptide named CFTR (cystic fibrosis transmembrane regulator). The hepatic manifestations include particular changes referring to the basic CFTR defect, iatrogenic lesions or consequences of the multisystem disease. Even though hepatobiliary disease is the most common non-pulmonary cause ofmortalityin CF (the third after pulmonary disease and transplant complications), only about the 33%ofCF patients presents clinically significant hepatobiliary disease. Conclusions Liver disease will have a growing impact on survival and quality of life of cystic fibrosis patients because a longer life expectancy and for this it is important its early recognition and a correct clinical management aimed atdelaying the onset of complications. This review could represent an opportunity to encourage researchers to better investigate genotype-phenotype correlation associated with the development of cystic fibrosis liver disease, especially for non-CFTR genetic polymorphisms, and detect predisposed individuals. Therapeutic trials are needed to find strategies of

    Nasopharyngeal cystic lesions are commonly encountered on magnetic resonance imaging with significantly overlapped imaging characteristics. The purpose of this study was to determine the prevalence and distinguishing imaging features of cystic lesions in the nasopharynx in the largest patient series to date. After institutional review board approval, consecutive head magnetic resonance images of 3000 patients performed at 1.5 T between June 2010 and April 2011 were retrospectively reviewed for cystic nasopharyngeal lesions. Location, size, and signal characteristic of cystic lesions were recorded. Electronic medical records were reviewed for patient demographics, symptoms, and underlying conditions. Among 3000 patients, 6% had Tornwaldt cysts (peak prevalence, 51-60 years old) and 10% had mucous retention cysts (peak prevalence, 41-50 years old). A significant correlation between human immunodeficiency virus infection and mucous retention cysts was observed (P cysts was slightly higher than previously described in the literature. Additionally, younger and older patients had the lowest prevalence of Tornwaldt cyst, suggesting these lesions are acquired and subsequently involute with time. A significant correlation was observed between human immunodeficiency virus infection and mucous retention cysts.

    The primary goal of mass screening programs for cystic fibrosis carriers should be to allow people to make more informed reproductive decisions. However, previous experience with genetic screening programs, including those for phenylketonuria and sickle cell disease, have revealed complex problems including error, confusion, and stigmatization. These problems could be greater with cystic fibrosis, since more than 8 million Americans may be carriers and entrepreneurial interests can be expected to promote screening in what could become a billion-dollar industry. The present frequency of the detectable mutation ({Delta}F{sub 508}), 75%, will complicate the counseling process. The sensitivity of the test to detect at-risk couples would be 56%. The cost of screening could be as much as $2.2 million for each cystic fibrosis birth avoided. Regardless of improvements in the detection rate, implementation of population screening should be delayed until pilot studies that demonstrate its safety and effectiveness are completed. While studies are in progress, preconception testing should be offered to adult relatives of cystic fibrosis patients as part of a comprehensive program following institutional review board approval for compassionate use.

    Full Text Available Introduction. Solid and cystic pseudopapillary tumor of the pancreas is a rare tumor of the pancreas, for the first time described by Frantz et al. in 1959. The majority of patients are young females and most of them are asymptomatic. Case Outline. We report a case of 25-year old woman who was admitted to our institution with abdominal pain and a palpable mass in the left hypochondrial area. US and CT scan revealed a solid and cystic pseudopapillary tumor in the head of the pancreas. The patient was treated by Whipple procedure, modification Longmire-Traverso. There was no metastatic disease either in the liver or peritoneum. Histologically the tumor was diagnosed as a solid and cystic pseudopapillary tumor of the pancreas. Conclusion. The unclear pre-operative diagnoses, together with incidence of potential malignancy as well as good outcome with resection, suggest that all suspected cystic tumors of the pancreas should be resected. The exact diagnosis is based on histological findings. [Projekat Ministarstva nauke Republike Srbije, br. III41007 i br. III41010

    The authors describe the case of a pregnant woman referred to the institution to be evaluated for an adnexal mass. Ultrasonography showed a voluminous solid-cystic lesion suggestive of ovarian neoplasm. Magnetic resonance imaging demonstrated that the lesion was located within the uterine serosa, suggesting the presence of a degenerated leiomyoma. A correct diagnosis of pelvic masses in pregnancy is essential for the definition of a therapeutic approach. Magnetic resonance imaging represents a relevant tool in the diagnosis of these abnormalities. (author)

    Full Text Available Objective: To understand the pathologic basis for sonographic features of complex cystic lesions. Methods: From 2 646 female patients underwent breast sonography at King Chulalongkorn Memorial Hospital from January 2005 through December 2010, 103 cystic lesions were included. Pathologic confirmation was performed by fine-needle aspiration (n=42, core needle biopsy (n=6, excision (n=54 and mastectomy (n=1. Complex cystic breast masses were classified into 3 types as followings; thick outer wall and/or thick internal septa (type I; thick septation and thick wall were defined as equal or more than 0.5 cm, masses containing mixed cystic and solid components (at least 50% of cystic component (type II, predominantly solid with eccentric cystic foci (at least 50% of solid component (type III. Results: In 103 complex cystic masses, there are 27 lesions (26% classified as type I cystic breast masses, 37 lesions (36% as type II cystic breast masses and 39 lesions (38% type III cystic breast masses, 26 lesions (25.2% are proved to be malignant. All of type I cystic breast masses in our study are benign, and 14 (38% of type II cystic breast masses and 12 lesions (31% of type III cystic breast lesions are proved to be malignant. Conclusions: Type II and III lesions should suggest possibility of malignancy and biopsy should be performed in all lesions. All type I lesion in this study are benign. None of other parameters we included in this study (size or margin can effectively differentiate between benign or malignant cystic breast lesions. Also, grading of the malignant lesions by using type of cystic breast mass cannot be applied.

    Chronic loss of appetite in cystic fibrosis concerns both individuals and families. Appetite stimulants have been used to help cystic fibrosis patients with chronic anorexia attain optimal body mass index and nutritional status. However, these may have adverse effects on clinical status. The aim of this review is to systematically search for and evaluate evidence on the beneficial effects of appetite stimulants in the management of CF-related anorexia and synthesize reports of any side-effects. Trials were identified by searching the Cochrane Cystic Fibrosis and Genetic Disorders Group's Cystic Fibrosis Trials Register, MEDLINE, Embase, CINAHL, handsearching reference lists and contacting local and international experts.Last search of online databases: 01 April 2014.Last search of the Cystic Fibrosis Trials Register: 08 April 2014. Randomised and quasi-randomised controlled trials of appetite stimulants, compared to placebo or no treatment for at least one month in adults and children with cystic fibrosis. Authors independently extracted data and assessed the risk of bias within eligible trials. Meta-analyses were performed. Three trials (total of 47 recruited patients) comparing appetite stimulants (cyproheptadine hydrochloride and megesterol acetate) to placebo were included; the numbers of adults or children within each trial were not always reported. The risk of bias of the included trials was graded as moderate.A meta-analysis of all three trials showed appetite stimulants produced a larger increase in weight z score at three months compared to placebo, mean difference 0.61 (95% confidence interval 0.29 to 0.93) (P children, appetite stimulants improved only two of the outcomes in this review - weight (or weight z score) and appetite; and side effects were insufficiently reported to determine the full extent of their impact. Whilst the data may suggest the potential use of appetite stimulants in treating anorexia in adults and children with cystic fibrosis

    The Italian Cystic Fibrosis Registry (ICFR) is based on a new agreement about the data flow towards the Registry signed on October, 4th 2016 by the Centre for Rare Diseases of the Italian National Institute of Health (NIH), the clinicians of the Italian National Referral and Support Centres for Cystic Fibrosis, the Paediatric Hospital "Bambino Gesù" (Rome), the Italian Cystic Fibrosis Society, and the Italian League for Cystic Fibrosis. The aim of the present Report is to improve the knowledge on cystic fibrosis (CF) through the epidemiological description of Italian patients. The members of the Scientific and Technical Committee have to write a report on data collected by ICFR, in order to contribute to achieve the aims of ICFR itself, i.e., to improve the care of CF patients. In particular, the Report should contribute to the following objectives: - to analyze the medium and long-term clinical and epidemiological trends of the disease; - to identify the main healthcare needs at regional and national level in order to contribute to the healthcare programmes and to the distribution of resources; - to compare Italian data with the international ones. Analyses and results described in the present Report are referred to patients in charge to the Italian National Referral and Support Centres for Cystic Fibrosis in the period 2011-2014. Data were sent by Centres by means of a specific software (Camilla, Ibis Informatica) and has undergone a double quality control (QC): the first by NIH and the second at a European level (before the inclusion of the Italian data within the European Cystic Fibrosis Registry). These QCs assure the completeness and accuracy of data as well as their consistency with European core data. A total of 29 different CF centres (referral, support, and Paediatric Hospital "Bambino Gesù") sent their data to ICFR; data referred to the period 2011-2014.

  10. Cystic fibroepithelioma of Pinkus: two new cases and cystic changes in classical fibroepithelioma of Pinkus

    Directory of Open Access Journals (Sweden)

    Zlatko Marusic

    2014-09-01

    Full Text Available We report two new cases of cystic fibroepithelioma of Pinkus together with immunohistochemical features and analyze the presence of cystic changes in a series of 16 classical fibroepitheliomas of Pinkus. Our findings show that the formation of cystic spaces is most probably caused by ischemic degeneration of stromal fenestrations, rather than by central tumor cell necrosis. This finding is supported by lack of CD34 positive blood vessels in edematous and hyalinized stromal fenestrations undergoing transformation into cystic spaces, as opposed to the uninvolved stromal fenestrations. Therefore, it is probably more accurate to refer to this process as pseudocystic stromal degeneration rather than true cyst formation. Also, two out of 16 classical Pinkus fibroepitheliomas exhibited focal pseudocystic changes in 50% and 10% of the tumor, respectively, demonstrating that this degenerative process can be found, rarely and focally, in classical cases as well.

    Background and purpose: To assess whether consensus guideline-based atlas-based auto-segmentation (ABAS) reduces interobserver variation and improves dosimetric parameter consistency for organs at risk (OARs) in nasopharyngeal carcinoma (NPC). Materials and methods: Eight radiation oncologists from 8 institutes contoured 20 OARs on planning CT images of 16 patients via manual contouring and manually-edited ABAS contouring. Interobserver variation [volume coefficient of variation (CV), Dice similarity coefficient (DSC), three-dimensional isocenter difference (3D-ICD)] and dosimetric parameters were compared between the two methods of contouring for each OAR. Results: Interobserver variation was significant for all OARs in manual contouring, resulting in significant dosimetric parameter variation (P < 0.05). Edited ABAS significantly improved multiple metrics and reduced dosimetric parameter variation for most OARs; brainstem, spinal cord, cochleae, temporomandibular joint (TMJ), larynx and pharyngeal constrictor muscle (PCM) obtained most benefit (range of mean DSC, volume CV and main ICD values was 0.36–0.83, 12.1–84.3%, 2.2–5.0 mm for manual contouring and 0.42–0.86, 7.2–70.6%, 1.2–3.5 mm for edited ABAS contouring, respectively; range of dose CV reduction: 1.0–3.0%). Conclusion: Substantial objective interobserver differences occur during manual contouring, resulting in significant dosimetric parameter variation. Edited ABAS reduced interobserver variation and improved dosimetric parameter consistency, particularly for brainstem, spinal cord, cochleae, TMJ, larynx and PCM

Psychological interventions are largely concerned with emotional and social adjustments, adherence to treatment and quality of life, however no systematic review of such interventions has been undertaken for this disease. To describe the extent and quality of effectiveness studies utilising psychological interventions for CF and whether these interventions provide significant psychosocial and physical benefits in addition to standard care. Relevant trials were identified from searches of Ovid MEDLINE, the Cochrane trial registers for CF and Depression, Anxiety and Neurosis Groups and PsychINFO; unpublished trials were located through professional networks and Listserves. Most recent search: April 2003. This review included RCTs and quasi-randomised trials. Study participants were children and adults diagnosed with CF, and their immediate family members. Psychological interventions were from a broad range of modalities and outcomes were primarily psychosocial, although physical outcomes and cost effectiveness were also considered. Two reviewers independently selected relevant trials and assessed their methodological quality. For binary and continuous outcomes a pooled estimate of treatment effect was calculated for each outcome. This review is based on the findings of eight studies, representing data from a total of 358 participants. Studies fell into four conceptually similar groups: (1) gene pre-test education counselling for relatives of those with CF (one study); (2) biofeedback, massage and music therapy to assist physiotherapy (three studies); (3) behavioural intervention to improve dietary intake in children up to 12 years (three studies); and (4) self-administration of treatments to improve quality of life in adults (one study). Interventions were largely educational or behavioural, targeted at specific treatment concerns

    This article presents a narrative review of cystic lesions around the hip and primarily consists of 5 sections: Radiological examination, prevalence, pathogenesis, symptoms, and treatment. Cystic lesions around the hip are usually asymptomatic but may be observed incidentally on imaging examinations, such as computed tomography and magnetic resonance imaging. Some cysts may enlarge because of various pathological factors, such as trauma, osteoarthritis, rheumatoid arthritis, or total hip arthroplasty (THA), and may become symptomatic because of compression of surrounding structures, including the femoral, obturator, or sciatic nerves, external iliac or common femoral artery, femoral or external iliac vein, sigmoid colon, cecum, small bowel, ureters, and bladder. Treatment for symptomatic cystic lesions around the hip joint includes rest, nonsteroidal anti-inflammatory drug administration, needle aspiration, and surgical excision. Furthermore, when these cysts are associated with osteoarthritis, rheumatoid arthritis, and THA, primary or revision THA surgery will be necessary concurrent with cyst excision. Knowledge of the characteristic clinical appearance of cystic masses around the hip will be useful for determining specific diagnoses and treatments. PMID:26495246

    Immunoreactive trypsin (IRT) was measured in dried blood spots from 160.822 five-day-old babies as a part of a regionwide neonatal screening program for cystic fibrosis. A second test was performed for 492 babies in whom blood IRT levels were found greater than 900 μg/l; retesting revealed persistent elevation in 55. Sweat testing confirmed cystic fibrosis in 43 babies, but results were normal in 12. During the course of this study, a total of 51 cystic fibrosis babies were identified: 43 by newborn screening, 6 because they had meconium ileus; so, early diagnosis was achieved in 49 cases out of 51. Two newborn babies did not have elevated IRT and they were missed by the screening test. Our results confirm that elevated blood IRT is characteristic of newborn babies with cystic fibrosis and show that this test has an excellent specificity (99.7%) and a good sensitivity (95%) when used as a neonatal screening test [fr

    Background and purpose: To examine control rates for predominantly cystic craniopharyngiomas treated with intracavitary phosphorus-32 (P-32). Material and methods: 22 patients with predominantly cystic craniopharyngiomas were treated at Indiana University between October 1997 and December 2006. Nineteen patients with follow-up of at least 6 months were evaluated. The median patient age was 11 years, median cyst volume was 9 ml, a median dose of 300 Gy was prescribed to the cyst wall, and median follow-up was 62 months. Results: Overall cyst control rate after the initial P-32 treatment was 67%. Complete tumor control after P-32 was 42%. Kaplan-Meier 1-, 3-, and 5-year initial freedom-from-progression rates were 68%, 49%, and 31%, respectively. Following salvage therapy, the Kaplan-Meier 1-, 3-, and 5-year ultimate freedom-from-progression rates were 95%, 95%, and 86%, respectively. All patients were alive at the last follow-up. Visual function was stable or improved in 81% when compared prior to P-32 therapy. Pituitary function remained stable in 74% of patients following P-32 therapy. Conclusions: Intracystic P-32 can be an effective and tolerable treatment for controlling cystic components of craniopharyngiomas as a primary treatment or after prior therapies, but frequently allows for progression of solid tumor components. Disease progression in the form of solid tumor progression, re-accumulation of cystic fluid, or development of new cysts may require further radiotherapy or surgical intervention for optimal long-term disease control.

    Improved therapy has substantially increased survival of persons with cystic fibrosis (CF). But the risk of colorectal cancer (CRC) in adults with CF is 5-10 times greater compared to the general population, and 25-30 times greater in CF patients after an organ transplantation. To address this risk, the CF Foundation convened a multi-stakeholder task force to develop CRC screening recommendations. The 18-member task force consisted of experts including pulmonologists, gastroenterologists, a social worker, nurse coordinator, surgeon, epidemiologist, statistician, CF adult, and a parent. The committee comprised 3 workgroups: Cancer Risk, Transplant, and Procedure and Preparation. A guidelines specialist at the CF Foundation conducted an evidence synthesis February-March 2016 based on PubMed literature searches. Task force members conducted additional independent searches. A total of 1159 articles were retrieved. After initial screening, the committee read 198 articles in full and analyzed 123 articles to develop recommendation statements. An independent decision analysis evaluating the benefits of screening relative to harms and resources required was conducted by the Department of Public Health at Erasmus Medical Center, Netherlands using the Microsimulation Screening Analysis model from the Cancer Innervation and Surveillance Modeling Network. The task force included recommendation statements in the final guideline only if they reached an 80% acceptance threshold. The task force makes 10 CRC screening recommendations that emphasize shared, individualized decision-making and familiarity with CF-specific gastrointestinal challenges. We recommend colonoscopy as the preferred screening method, initiation of screening at age 40 years, 5-year re-screening and 3-year surveillance intervals (unless shorter interval is indicated by individual findings), and a CF-specific intensive bowel preparation. Organ transplant recipients with CF should initiate CRC screening

    Genzyme is developing therapies to replace the defective forms of the cystic fibrosis (CF) transmembrane conductance regulator (CFTR) protein in CF patients. The company is developing a gene therapy, as well as a recombinant production of CFTR for protein replacement therapy. Both approaches have been granted orphan drug status by the FDA [156348]. The results of several clinical trials were discussed at the first annual meeting of the American Society of Gene Therapy in May 1998. A single dose nasal administration was well tolerated by volunteers, but had disappointing efficacy. In a study completed at the Royal Brompton Hospital, London, a single dose aerosol application of GL-67:DOPE was administered to eight patients, while another eight received GL-67:DOPE plus pCF1-CFTR. In the second group, a moderate increase in the potential difference in the lung was observed, with a slight trend towards bacterial adherence normalization in the airway cells. Seven of the patients in the second group, and three patients who received lipid alone, developed, flu-like symptoms within 24 h. A trial at the University of Alabama, using the same formulation, showed that flu-like symptoms developed in six of eight patients by day two, and in all patients by day seven [290120]. In 1995, the company began a clinical safety trial involving delivery of a normal CF gene to the patient's lungs via an adenovirus vector. The administration involves the inhalation of an aerosol containing the vector or, separately, delivery to one lobe of the patient's lung via a bronchoscope [191678]. To evaluate additional delivery methods for the gene, Genzyme has an exclusive research agreement for the use of Vical's cytofectins as non-viral delivery vectors for CFTR. Also under investigation are delivery systems for the nasal epithelium using liposomes or lipid-DNA complexes. These protocols are being developed in collaboration with the National Heart & Lung Institute, London, and an undisclosed

    Follicular thyroid carcinoma (FTC) is considered as a disease of the elderly with a higher incidence in females as compared to papillary thyroid carcinoma (PTC). Some studies have reported its occurrence at an early age, which may be attributed to early diagnosis because of the availability of advanced techniques. The prognosis of the disease is considered poor as compared to that of PTC. The conclusions drawn in this review are based on 663 cases in whom adequate data was available for meaningful analysis followed for a mean period of 9.2 years, median, 7.8 years; range, 1-32 years

    Full Text Available Hydatic cyst is an illness that appears in consequence of the cystic form of small strap-shaped worm Echinococcus granulosis. Frequently, cysts exist in the lungs and liver. Peritoneal involvement is rare, and generally occurs as a result of second inoculation from rupture of a liver-located hydatic cyst. Primary ovarian hydatic cyst is very rare. A 56-year-old female patient was admitted to Emergency Service with the complaint of stomachache and swollen abdomen. From ultrasonographic examination, a right ovarian 52 × 45-mm heterogeneous semi-solid cystic mass and right hydronephrosis were detected. As a result of the tomographic examination, the right ovarian growth was judged to be a 60 × 45-mm lobule contoured, septal, heterogeneously cystic mass (ovarian carcinoma. Depending on these indicators and with the diagnosis of ovarian carcinoma, laparotomy was planned. During the observation, a mass that compressed on the right ureter and dilatation in the right ureter were determined. The mass was approximately 6 cm long and smoothly contoured, including widespread adhesions, and also obliteration of the pouch of Douglas. The mass was excised and total abdominal hysterectomy and bilateral salpingo-oopherectomy performed. After a pathological examination, hydatid cyst was diagnosed. Although pointing at the issue of the distinctive diagnosis of pelvic and peritoneal mass, it should be realized that the existence of primary peritoneal and pelvic involvement of the hydatic cyst is generally a result of the second inoculation, and is also more common in regions in which Echinococcus granulosa is endemic and livestock production is prevalent.

    Nutrition is thought to influence disease status in patients with cystic fibrosis (CF). This cross-sectional study sought to evaluate nutrient intake and anthropometric data from 64 adult outpatients with cystic fibrosis. Nutrient intake from food and supplements was compared with the Dietary Reference Intakes for 16 nutrients and outcomes influenced by nutritional status. Attention was given to vitamin D and calcium given potential skeletal implications due to cystic fibrosis. Measurements included weight, height, body composition, pulmonary function, and serum metabolic parameters. Participants were interviewed about dietary intake, supplement use, pulmonary function, sunlight exposure, and pain. The participants’ mean body mass index (±standard deviation) was 21.8±4.9 and pulmonary function tests were normal. Seventy-eight percent used pancreatic enzyme replacement for malabsorption. Vitamin D deficiency [25-hydroxyvitamin D (25OHD)<37.5 nmol/L] was common: 25 (39%) were deficient despite adequate vitamin D intake. Lipid profiles were normal in the majority, even though total and saturated fat consumption represented 33.0% and 16.8% of energy intake, respectively. Reported protein intake represented 16.9% of total energy intake (range 10%–25%). For several nutrients, including vitamin D and calcium, intake from food and supplements in many participants exceeded recommended Tolerable Upper Intake Levels. Among adults with cystic fibrosis, vitamin D deficiency was common despite reported adequate intake, and lipid profiles were normal despite a relatively high fat intake. Mean protein consumption was adequate, but the range of intake was concerning, as both inadequate or excessive intake may have deleterious skeletal effects. These findings call into question the applicability of established nutrient thresholds for patients with cystic fibrosis. PMID:18060897

    Purpose: To clarify if the portal venous phase is helpful for the differential diagnosis of groove pancreatic carcinomas and groove pancreatitis. Materials and methods: MDCT and MRI of groove pancreatic carcinomas (n = 7) and groove pancreatitis (n = 15) were retrospectively reviewed by two radiologists independently. The signal intensity on T2-weighted images was subjectively assessed. The presence or absence of common bile duct (CBD) and main pancreatic duct (MPD) strictures, calcifications, and cystic lesions was evaluated. Additionally, the appearance of groove pancreatic carcinoma and that of groove pancreatitis in the portal venous phase on dynamic MDCT and MRI were compared. Results: There were no significant differences in the signal intensity on T2-weighted images and in the presence or absence of CBD and MPD strictures, calcifications, and cystic lesions between groove pancreatic carcinomas and groove pancreatitis. However, patchy focal enhancement in the portal venous phase was more commonly observed in groove pancreatitis than groove pancreatic carcinoma (Reviewers 1 and 2: 14/15 [93.3%] vs. 1/7 [14.3%], P < 0.0001). In addition, peripheral enhancement was only seen in groove pancreatic carcinomas (Reviewer 1: 4/7 [57.1%] vs. 0/15 [0%], P < 0.005, and Reviewer 2: 3/7 [42.9%] vs. 0/15 [0%], P < 0.05). Conclusion: The portal venous phase may be helpful for the differential diagnosis of groove pancreatic carcinomas and groove pancreatitis.

    The aim is to present the variety of signs and symptoms from the diagnostic imaging methods of atypical neoplasms of the pancreas, presented as a type of cystic lesions. This often leads to unnecessary surgery or inappropriate tracking. In 115 patients (85 men and 30 women) with cystic lesions of the pancreas ultrasonic (US),computer tomography (CT) and magnetic resonance imaging (MRI) were performed and verified through histological and macroscopic pathology preparations. The ultrasound machines equipped with linear and convex transducers, MDCT and MRI imaging systems were used. In 14 of 115 patients atypical neoplasms of the pancreas were diagnosed: two cases with macroscopic serous cystic neoplasms, two nonmucinous cystic neoplasms, two hemorrhagic mucinous neoplasms, two ductal adenocarcinomas with cystic changes, one islet cell cystic tumor, two lymphoepithetial cysts, one lymphangioma, one solid papillary epithelial neoplasm and one mucinous adenocarcinoma. The authors take into consideration and overlapping of clinical symptoms and laboratory tests. Although much of the imaging features and morphological characteristics of cystic neoplasms of the pancreas are well known, should be known about the atypical unusual images in so-called 'typical' cystic neoplasms, cystic images in solid neoplasms and various atypical tumors with cystic lesions.

    Nasal polyposis is often found in patients with cystic fibrosis. To assess the incidence of nasal polyposis, the response to medical treatment, recurrence and the need for surgical intervention in children and adolescents with cystic fibrosis during a three-year follow-up. Clinical symptoms (pulmonary, pancreatic insufficiency, malnutrition, nasal obstruction), two positive sweat chloride tests, and genotype findings in 23 patients with cystic fibrosis were analyzed. All patients underwent nasal endoscopy every 12 months from January 2005 to December 2007, to assess the presence and grade of Nasal Polyps. Nasal polyposis, when present, were treated with topical corticosteroids for 6-12 months, with progress being evaluated within the 3 years of follow-up. In the first evaluation, nasal polyposis was diagnosed in 30.43% of patients (3 bilateral and 4 unilateral), recurrent pneumonia in 82.6%, pancreatic insufficiency in 87%, and malnutrition in 74%. The presence of nasal polyposis was not associated with chloride values in the sweat, genotype, clinical signs of severity of cystic fibrosis, or nasal symptoms. In the three-year period of follow up, 13 patients (56.52%) had at least one event of polyposis, with the youngest being diagnosed at 32 months of age. Only one patient underwent surgery (polypectomy), and there was one diagnosis of nasopharyngeal carcinoma. The study showed a high incidence of nasal polyposis. Monitoring through routine endoscopy in patients with cystic fibrosis, even in the absence of nasal symptoms, is highly recommended. The therapy with topical corticosteroids achieved good results. Thus, an interaction between pediatricians and otolaryngologists is necessary. Copyright © 2016 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

    To determine the changes in indications for orbital exenteration over 20 years and to assess its impact on patient survival. Evolving techniques of rehabilitation of the orbit in our institution were also evaluated. This was a retrospective review of hospital records of patients who underwent orbital exenteration from 1995 to 2015 in a tertiary care center. Data extracted included primary location of the tumor, preoperative treatments, interval between initial diagnosis and exenteration, status of surgical margins, presence of metastatic disease, and postoperative survival. The types of prosthesis utilized over the years were also reviewed. Cox regression analysis was performed for categorical variables. Kaplan-Meier analysis was used to estimate post-exenteration survival. Over a 20-year period, orbital exenteration was performed on 100 orbits of 100 patients. The mean age was 39.4 years (range: 2 months to 90 years). The most common indications among 98 malignant causes were retinoblastoma, squamous cell carcinoma, basal cell carcinoma, extraocular extension of uveal melanoma, and conjunctival melanoma. Postoperative survival was significantly related to age and tumor location but independent from gender, surgical margin, histopathological diagnosis, previous treatment modality, and preoperative interval. In the whole cohort, 1-year and 5-year survival rates were 97% and 84%, respectively. Exenteration appears to be life-saving in children with orbital extension of retinoblastoma. While patients exenterated for malignant eyelid tumors have the best chance of survival, those with orbital extension of uveal melanoma and adenoid cystic carcinoma of the lacrimal gland have the worst prognosis.

    Physical exercise training may form an important part of regular care for people with cystic fibrosis. This is an update of a previously published review. To assess the effects of physical exercise training on exercise capacity by peak oxygen consumption, pulmonary function by forced expiratory volume in one second, health-related quality of life and further important patient-relevant outcomes in people with cystic fibrosis. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of the most recent search: 04 May 2017.We searched ongoing trials registers (clinicaltrials.gov and the WHO ICTRP). Date of most recent search: 10 August 2017. All randomised and quasi-randomised controlled clinical trials comparing exercise training of any type and a minimum duration of two weeks with conventional care (no training) in people with cystic fibrosis. Two authors independently selected studies for inclusion, assessed methodological quality and extracted data. The quality of the evidence was assessed using the GRADE system. Of the 83 studies identified, 15 studies which included 487 participants, met the inclusion criteria. The numbers in each study ranged from nine up to 72 participants; two studies were in adults, seven were in children and adolescents and six studies included all age ranges. Four studies of hospitalised participants lasted less than one month and 11 studies were outpatient-based, lasting between two months and three years. The studies included participants with a wide range of disease severity and employed differing levels of supervision with a mixture of types of training. There was also wide variation in the quality of the included studies.This systematic review shows very low- to low-quality evidence from both short- and long-term studies that in people

    Human papillomavirus-related oropharyngeal squamous cell carcinoma is associated with cystic lymph nodes on CT and has a favorable prognosis. A subset of patients with aggressive disease experience treatment failure. Our aim was to determine whether the extent of cystic lymph node burden on staging CT can serve as an imaging biomarker to predict treatment failure in human papillomavirus-related oropharyngeal squamous cell carcinoma. We identified patients with human papilloma virus-related oropharyngeal squamous cell carcinoma and staging neck CTs. Demographic and clinical variables were recorded. We retrospectively classified the metastatic lymph node burden on CT as cystic or solid and assessed radiologic extracapsular spread. Biopsy, subsequent imaging, or clinical follow-up was the reference standard for treatment failure. The primary end point was disease-free survival. Cox proportional hazard regression analyses of clinical, demographic, and anatomic variables for treatment failure were performed. One hundred eighty-three patients were included with a mean follow-up of 38 months. In univariate analysis, the following variables had a statistically significant association with treatment failure: solid-versus-cystic lymph nodes, clinical T-stage, clinical N-stage, and radiologic evidence of extracapsular spread. The multivariate Cox proportional hazard model resulted in a model that included solid-versus-cystic lymph nodes, T-stage, and radiologic evidence of extracapsular spread as independent predictors of treatment failure. Patients with cystic nodal metastasis at staging had significantly better disease-free survival than patients with solid lymph nodes. In human papilloma virus-related oropharyngeal squamous cell carcinoma, patients with solid lymph node metastases are at higher risk for treatment failure with worse disease-free survival. Solid lymph nodes may serve as an imaging biomarker to tailor individual treatment regimens. © 2017 by American Journal

    Over the previous 50 years survival of patients with cystic fibrosis has progressively increased. As a result of improvements in health care, increasing numbers of patients with cystic fibrosis are now considering starting families of their own. For the health care professionals who look after these patients, the assessment of the potential risks, and the process of guiding prospective parents through pregnancy and beyond can be both challenging and rewarding. To facilitate appropriate discussions about pregnancy, health care workers must have a detailed understanding of the various important issues that will ultimately need to be considered for any patient with cystic fibrosis considering parenthood. This review will address these issues. In particular, it will outline pregnancy outcomes for mothers with cystic fibrosis, issues that need to be taken into account when planning a pregnancy and the management of pregnancy for mothers with cystic fibrosis or mothers who have undergone organ transplantation as a result of cystic fibrosis.

    Intraabdominal cystic lymphangiomas are rare and are located in retroperitoneum, mesentery, omentum and other visceral organs. Lymphangiomas of the ovary are rare and are usually unilateral. Cases with bilateral cystic lymphangiomas of the ovary are reported very rarely in literature. We report a rare case of bilateral cystic lymphangioma of ovary associated with chylous ascites in a 35-year-old lady who presented with complaints of severe dysmenorrhoea and oligomenorrhoea since 6 months with history of chyluria for the past 3 years.

    Congenital cystic adnomatoid malformation (CCAM) is rare pulmonary cystic disease. CCAM has been detected on prematurity, stillborn and respiratory distress infant or child by chest X-ray film and CT scan. One case of CCAM diagnosed in utero at gestational age 22 weeks is reported with sonographic findings and autopsy findings. Ultrasonographic findings are large cystic lesion in fetal thorax and fetal hydrops without hydramnios. The survival of these infants is very poor despite accurate prenatal diagnosis and maximal postnatal care

    A nonerosive form of rheumatoid arthritis (R.A.) was found in 62 patients out of 660 patients with R.A.. These 62 patients exhibit slowly progressive cystic changes in about the same joints in which usually erosions develop in classic R.A.. The E.S.R. is often low, half of the patients remained seronegative and there are 35 males and 27 females in the group. A smaller group of 15 out of these patients could be followed from a stage wherein the radiographs were normal to a stage of extensive cystic changes, over a period of at least 6 years. An attempt is made to delineate this group within the rheumatoid arthritis disease entity. (orig.) [de

    Cystic fibrosis is the most common autosomal recessive disease in white populations, and causes respiratory dysfunction in the majority of individuals. Numerous types of respiratory muscle training to improve respiratory function and health-related quality of life in people with cystic fibrosis have been reported in the literature. Hence a systematic review of the literature is needed to establish the effectiveness of respiratory muscle training (either inspiratory or expiratory muscle training) on clinical outcomes in cystic fibrosis. This is an update of a previously published review. To determine the effectiveness of respiratory muscle training on clinical outcomes in people with cystic fibrosis. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials register comprising of references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of most recent search: 17 April 2018.A hand search of the Journal of Cystic Fibrosis and Pediatric Pulmonology was performed, along with an electronic search of online trial databases up until 07 May 2018. Randomised controlled studies comparing respiratory muscle training with a control group in people with cystic fibrosis. Review authors independently selected articles for inclusion, evaluated the methodological quality of the studies, and extracted data. Additional information was sought from trial authors where necessary. The quality of the evidence was assessed using the GRADE system MAIN RESULTS: Authors identified 19 studies, of which nine studies with 202 participants met the review's inclusion criteria. There was wide variation in the methodological and written quality of the included studies. Four of the nine included studies were published as abstracts only and lacking concise details, thus limiting the information available. Seven studies were parallel studies and two of a cross-over design. Respiratory

    1999-01-01

    Papillary carcinoma of the thyroid (PTC) constitutes a major proportion of all thyroid cancers and is generally believed to be a slow growing tumor with an indolent course. The diagnosis of PTC often makes the physician overly optimistic and complacent and yet this tumor can be aggressive in a subset of patients leading to death in a few months. The fundamental but subtle differences underlying the extremes in biologic behaviour of this complex and fascinating tumor remain poorly understood. Although there is a general agreement among the investigators regarding prognostic factors, controversy exists about the management of the disease. There is divided opinion with respect to the type and extent of surgery and the need for radioiodine (1 31 I) treatment in case of PTC. The experiences at Radiation Medicine Centre (RMC) of 1904 cases of differentiated thyroid carcinoma (DTC) registered during the period 1963-1990 are reviewed

    In this document the case of a 66-year old woman is presented, with record of multi nodular goiter of 5 year of evolution, which is derived to scan ultrasound office to make a puncture-aspiration with thin needle because of the growth of nodular thyroid injuries. The ultrasound scan examination made before the puncture determine multiple dominant nodules of hyperplasia aspect between 15 and 25 mm of diameter and a small nodule of 6 mm suspected proliferate process. Despite its size, it was decided to include small nodule in injuries to a biopsy. The cytological study reveals nodular hyperplasia with carcinoma in the small nodule of 6 mm. A thyroidectomy is practiced on the patient. The deferred histological study of the thyroid gland confirms the finding of multi-nodular goiter with a small focus of papillar carcinoma.

    The pancreatic regions of 18 patients with cystic fibrosis were analyzed with a 1.5 Tesla MR unit. Signal intensity of the pancreas was correlated with clinical data and ultrasound. A hyperintense pancreas on T1-weighted image was consistent with fatty replacement of pancreatic insufficiency. A pancreas of normal soft tissue intensity was found in two asymptomatic and one symptomatic patient. A very hypointense pancreas on any pulse sequence was considered to be an intermediate stage of pancreatic degeneration. (orig.)

    Chemical dissolution and extracorporeal shock wave lithotripsy are promising new methods for the treatment of cholelithiasis without cholecystectomy. Nonsurgical defunctionalization of the gallbladder is now required to prevent recurrent stone formation. The authors consider cystic duct occlusion to be the first step. Ten domestic pigs underwent transcatheter electrocoagulation of the cystic duct via a cholecystostomy under fluoroscopic control. Stricture formation was followed by complete cystic duct occlusion in all ten cases. After a follow-up period ranging from 2 to 17 weeks (mean, 13 weeks), the animals were killed. Histologic studies demonstrated that complete obliteration of the cystic duct lumen was due to fibrous scar formation

    Cystic fibrosis transmembrane conductance regulator (CFTR) functions as a channel that regulates the transport of ions and the movement of water across the epithelial barrier. Mutations in CFTR, which form the basis for the clinical manifestations of cystic fibrosis, affect the epithelial innate immune function in the lung, resulting in exaggerated and ineffective airway inflammation that fails to eradicate pulmonary pathogens. Compounding the effects of excessive neutrophil recruitment, the mutant CFTR channel does not transport antioxidants to counteract neutrophil-associated oxidative stress. Whereas mutant CFTR expression in leukocytes outside of the lung does not markedly impair their function, the expected regulation of inflammation in the airways is clearly deficient in cystic fibrosis. The resulting bacterial infections, which are caused by organisms that have substantial genetic and metabolic flexibility, can resist multiple classes of antibiotics and evade phagocytic clearance. The development of animal models that approximate the human pulmonary phenotypes—airway inflammation and spontaneous infection—may provide the much-needed tools to establish how CFTR regulates mucosal immunity and to test directly the effect of pharmacologic potentiation and correction of mutant CFTR function on bacterial clearance.

    Since the 20 last years, the median age of survival has dramatically improved in children suffering from cystic fibrosis and complications such as growth retardation, pubertal delay and low bone mineral density are now more often than not observed in affected adolescents. The severity of the disease and the poor nutritional status due to pancreatic insufficiency and malabsorption are commonly implicated but recent data suggest that the disease could also play a role though the alteration of the chlore chanel (CFTR). Furthermore an increase prevalence of glucose intolerance and diabetes due to the progressive β cells destruction is observed in these children that make the life sometimes difficult for these adolescents already affected by an heavy chronic disease. The monitoring of the children should thus now become pluridisciplinary and include regular clinical evaluation of height and pubertal status, mineral bone density by DEXA and OGTT every two years since 10 years of age. Therefore, in addition to the standard treatment of cystic fibrosis is now added the vitamin D supplementation, the subcutaneous insulin therapy and may be the growth hormone that could be a new therapeutic demonstrating beneficial effects in these chronic disease. However further studies need to be performed to improve the management of these new endocrine complications more and more frequent in children and adolescents suffering from cystic fibrosis.

    Purpose: The aim of the study concerning congenital cystic lung malformations was to evaluate prenatal diagnoses postnatally to determine prognostic factors as well as to define optimized perinatal management. Materials and Methods: The study is based on 45 prenatal ultrasound examinations depicting fetal cystic lung lesions. 32 of the mothers had follow-up examinations. 5 pregnancies were terminated due to CCAM and additional malformations. Complete regression of the lesions was seen prenatally in 8 cases and postnatally in 5 children. Results: Surgical intervention due to respiratory insufficiency was necessary in 4 neonates. According to the imaging results, CCAM was present in 4 cases and sequestration in 7 patients. No correlation between the imaging findings and the surgical results was found in 3 children: One child suffered from rhadomyoid dysplasia, and in the case of the second child, a left-sided hernia of the diaphragm and additional sequestration were detected. The third child showed AV malformation. The cystic lesions of the 14 children operated upon were proven histologically. The degree of accuracy in the present study was high. Conclusion: Precise perinatal management is warranted in order to determine according to the clinical relevance surgical intervention and to prevent complications after the first year of life. This is performed during the neonatal period for respiratory insufficient neonates and within the first year of life for clinically stable children. (orig.)

    Thirty-one patients with malignant tumors of the middle ear and external auditory canal (EAC) were observed at the University of Virginia Hospital from 1956 through 1980. Of 27 patients with carcinoma, 21 had squamous cell carcinoma, 4 had basal cell carcinoma and 2 had adenoid cystic carcinoma. The 27 patients with carcinoma are reviewed with regard to clinical presentation, treatment modality, results and complications. The majority (67%) of patients had a history of chronic ear drainage, 22% had a previous mastoidectomy or polypectomy and 7% had an associated cholesteatoma. Eighty percent of patients with carcinoma limited to EAC were alive and well at 5 years, compared to 43% of patients with involvement of the middle ear. Fifty-six percent of patients without invasion of the petrous bone were alive at 5 years compared to only 20% of patients with petrous bone involvement. The data strongly suggest that survival depends on the extent of disease. The corrected disease free 5 year survival rates were 14% for patients who had surgery alone and 50% for those who had surgery and radiotherapy. Of the three patients with advanced disease who received radiotherapy alone, none survived five years

    Poor nutrition occurs frequently in people with cystic fibrosis and is associated with other adverse outcomes. Oral calorie supplements are used to increase total daily calorie intake and improve weight gain. However, they are expensive and there are concerns they may reduce the amount of food eaten and not improve overall energy intake. This is an update of a previously published review. To establish whether in people with cystic fibrosis, oral calorie supplements: increase daily calorie intake; and improve overall nutritional intake, nutritional indices, lung function, survival and quality of life. To assess adverse effects associated with using these supplements. We searched the Cochrane Cystic Fibrosis Trials Register comprising references from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. We contacted companies marketing oral calorie supplements.Last search: 18 October 2016. Randomised or quasi-randomised controlled trials comparing use of oral calorie supplements for at least one month to increase calorie intake with no specific intervention or additional nutritional advice in people with cystic fibrosis. We independently selected the included trials, assessed risk of bias and extracted data. We contacted the authors of included trials and obtained additional information for two trials. We identified 21 trials and included three, reporting results from 131 participants lasting between three months and one year. Two trials compared supplements to additional nutritional advice and one to no intervention. Two of the included trials recruited only children. In one trial the risk of bias was low across all domains, in a second trial the risk of bias was largely unclear and in the third mainly low. Blinding of participants was unclear in two of the trials. Also, in one trial the clinical condition of groups appeared to be unevenly balanced at baseline and in another trial there were

    Objective: To assess the usefulness of computerized tomography (CT) in the characterization of renal masses, in order to stage them, determine their prognosis and their appropriate clinical and/or surgical management. Material and Methods: Between 1988 and 2001, we selected 63 patients with renal tumors that had been examined by pathology. Patient's ages ranged from 16 to 88 years (25 women, 38 men). The studies were performed with a sequential helical CT, using 5 mm thickness sections every 5mm evaluating the cortico medullar and nephrographic phases. Renal tumors were characterized and staged without any knowledge about the pathological findings; subsequently the tomographic characteristics were compared to such findings. The following characteristics were evaluated: 1) mixed solid-cystic nature; 2) size; 3) borders; 4) enhancement; 5) necrosis; 6) hemorrhage; 7) central scar; 8) presence of fat; 9) collecting system; 10) capsular invasion; 11) perirenal fat invasion; 12) vessels; 13) Gerota's fascia; 14) lymph nodes; and 15) local and/or distant metastases. Results: Of the 63 tumors, 2 were complicated cysts; of the 61 remaining tumors, 10 were angiomyolipomas, 1 was a renal lymphoma, 1 was a focal xantogranulomatose pyelonephritis, 1 was a metanephric adenoma, 3 papillary renal cell carcinoma (RCC), 4 transitional cell tumors, 4 oncocytomas, 37 clear cell renal carcinoma. The CT could correctly characterize the 2 cystic tumors as such, as well as the 9 angiomyolipomas and the 4 transitional cell tumors. The 48 other tumors (1 angiomyolipoma, 1 lymphoma, 1 focal xantogranulomatose pyelonephritis, 1 metanephric adenoma, 3 papillary RCC, 4 oncocytomas, and 37 cell renal carcinomas) remaining were characterized as renal adenocarcinomas and CT staged. Conclusion: CT is a useful method to characterize renal masses since it determines their solid-cystic or fatty structure; aiding in many cases to define a surgical treatment. For the CT staging of renal tumors, the

    Allogenic bone grafts have been used after various processing in each institute was made by lyophilized allogenic bone and used for maxillofacial reconstruction. Three types of lyophilized allogenic bone grafts as powder, chip and block form were performed to reconstruct the following defects: 1) maxillectomy, 2) mandiblectomy, 3) cystectomy, 4) cleft alveolus, 5) gap in orthognathic osteotomy, 6) peri-implant defect, 7) extraction socket, and 8) facial contouring. Above defects can be classified as cystic and discontinuity defects of the maxilia and the mandible. Because discontinuity defects have more difficult problems to reconstruct considering mechanical strength of the allogenic bone. We performed allogenic bone grafts on 50 cystic defects and 12 discontinuity defects of the jaws. Among them, 3 cases were removed due to infection, and the others had no complications. In reconstruction of cystic defects, the defects were filled with allogenic chip which were made from allogenic block bone at the surgery, which later were changed to host bone. Three cases of them showed tooth eruption through the allogenic bone grafting site, changing the eruption pathway, which was interrupted by the lesion. in reconstruction of discontinuity defects, usually allogenic bone has been used as a tray, in which PMCB or demineralized bone chips were filled. But we tried to reconstruct this discontinuity defect using allogeneic bone block without inside filling of PMCB different from tray type. We will present the results of allogenic bone grafts using cranial bone, costochondral graft, and the mandible

    To investigate a computed tomographic (CT) protocol with iterative reconstruction at conventional radiography dose levels for the assessment of structural lung abnormalities in patients with cystic fibrosis ( CF cystic fibrosis ). In this institutional review board-approved study, 38 patients with CF cystic fibrosis (age range, 6-58 years; 21 patients 18 years) underwent investigative CT (at minimal exposure settings combined with iterative reconstruction) as a replacement of yearly follow-up posteroanterior chest radiography. Verbal informed consent was obtained from all patients or their parents. CT images were randomized and rated independently by two radiologists with use of the Bhalla scoring system. In addition, mosaic perfusion was evaluated. As reference, the previous available conventional chest CT scan was used. Differences in Bhalla scores were assessed with the χ(2) test and intraclass correlation coefficients ( ICC intraclass correlation coefficient s). Radiation doses for CT and radiography were assessed for adults (>18 years) and children (chest CT protocol can replace the two yearly follow-up chest radiographic examinations without major dose penalty and with similar diagnostic quality compared with conventional CT.

    Hepatocellular carcinoma (HCC) is a common cause of cancer mortality. Hepatitis B and C viruses, aflatoxin and alga toxin in the contaminated drinking water are the major etiological factors. Rapidly progressing medical imaging has resulted in the improved treatment results. Surgical resection has a major role for influencing prognosis of HCC. Local cancer therapies based on the advances in early diagnosis are progressing rapidly. Multimodality combination and sequential treatment has proved effective, unfortunately systemic chemotherapy for HCC remains disappointed. All of these have resulted in the improved prognosis of HCC.

    Purpose: We evaluated the sonographic findings that can help differentiate widely invasive follicular thyroid carcinomas (WIFTC) from minimally invasive follicular thyroid carcinomas (MIFTC). Methods: We retrospectively compared the sonographic and clinical findings of 24 patients (M:F = 5:19) with 24 MIFTCs and 12 patients (M:F = 1:11) with 13 WIFTCs that were confirmed pathologically and available in sonography at our institution between 1995 and 2007. Results: WIFTC was more common in elderly patients than MIFTC (p < 0.0001). WIFTC was seen with a larger size than MIFTC (p = 0.0092). The best cut-off values for age and size were 49 years and 5.6 cm, respectively. On sonography, all tumors were seen as a well-defined oval or round mass. Heterogeneous mulberry-like echotexture was more common for WIFTC than for MIFTC (77% vs. 25%) (p = 0.0046). The presence of calcifications was more frequent in WIFTC than in MIFTC (54% vs. 8%) (p = 0.0041). Ring calcifications (86%) were the most common type for WIFTC. WIFTC was commonly hypoechoic (70%) and rarely cystic change (8%), but without statistical differences. When WIFTCs represented tumors with two or more findings with a statistical difference, the specificity was 96%. Conclusion: WIFTC is distinguishable from MIFTC by sonography for patients with an age ≥49 years, a tumor ≥5.6 cm, a heterogeneous mulberry-like echotexure, or the presence of calcifications. The sonographic impression of a WIFTC can support a preoperative or intraoperative diagnosis of a difficult case as determined by FNA or with a frozen section.

    To evaluate radiological findings in patients submitted to surgical treatment for medullary breast cancer at Instituto Nacional de Cancer (INCa), Rio de Janeiro, RJ, Brazil, correlating them with histological results. A retrospective descriptive study was developed with patients submitted to surgery at INCa, in the period from January 1997 to December 2006, for identifying the presence of medullary breast carcinoma and analyzing radiological findings. Among 21,287 patients diagnosed with carcinoma, 76 (0.357%) had typical medullary breast carcinoma. The age range of these patients was 32-81 years (mean = 59.1 years). Mammography demonstrated lesions in 19 of these patients, 17 (89.5%) of them with masses, and 2 with focal asymmetry. Among the patients with masses, 15 (88.1%) presented with high density and 2 (11.9%) with isodensity. Twelve patients presented sonographic findings, 11 (91.6%) of them with hypoechoic masses, and one with an anechoic mass with areas of cystic degeneration. Nodular mass was the predominant radiological finding (89.5%), 88.1% of them corresponding to masses with high density and circumscribed margins. Despite the radiological characteristics of benignity, a solid, fast growing, highly dense mass with circumscribed margins should be further investigated to confirm the diagnosis. (author)

    Full Text Available To probe the magnetic resonance imaging (MRI features of ovarian clear cell carcinoma (OCCC.This study retrospectively collected MRI data for 21 pathology-confirmed OCCCs from 19 female patients. The MRI findings were analyzed to determine the tumor size, shape/edge, shape and number of protrusions within the cyst, cystic or necrotic components, signal intensity (SI and enhancement features.The age of the 19 patients ranged from 28 to 63 years (mean age: 53 years. Unilateral tumors were found in 17 patients (17/19, 89%; the average size of all tumors was 10.8 cm. The tumors on MRI were classified into two categories: (a "cystic adnexal mass with solid protrusions" in 12 (57% and (b "solid adnexal mass with cystic areas or necrosis" in 9 (43%. For group a, high to very high SI was observed for most tumors (10/12, 83% on T1-weighted images (T1WIs, and very high SI was observed on T2-weighted images (T2WIs for all 12 tumors. Most solid protrusions were irregular and few in number and exhibited heterogeneous intermediate SI on T1WIs and T2WIs and prolonged enhanced SI in the contrast study. All 9 OCCCs in group b were predominantly solid masses with unequally sized necrotic or cystic areas in which some cysts were located at the periphery of the tumor (4/9, 44%. The solid components in all 9 tumors showed iso- or slightly high SI on T1WIs, heterogeneous iso-high SI on T2WIs and heterogeneous prolonged enhancement. According to FIGO classification, 14 tumors (14/19, 74% were stages I-II, and 5 (5/19, 26% were stages III-IV.On MRI, OCCCs present as large unilateral multilocular or unilocular cystic masses with irregular intermediate SI solid protrusions or predominantly solid masses with cysts or necrosis at an early FIGO stage.

    2011-04-01

    Full Text Available Mucinous cystic neoplasms (MCNs make up a morphologic family of similar appearing tumors arising in the ovary and various extraovarian organs such as pancreas, hepatobiliary tract and mesentery. MCNs of the pancreas occur almost exclusively in women. Here, we report a rare case of MCN in a male patient. A 39-year-old man was admitted to our hospital with the chief complaint of back pain. Abdominal computed tomography revealed a multilocular cyctic mass 6.3 cm in diameter in the pancreatic tail. In addition, the outer wall and septae with calcification were demonstrated in the cystic lesion. On magnetic resonance imaging , the cystic fluid had low intensity on T1-weighted imaging and high intensity on T2-weighted imaging. Endoscopic retrograde cholangio-pancreatography (ERCP showed neither communication between the cystic lesion and the main pancreatic duct nor encasement of the main pancreatic duct. Endoscopic ultrasonography revealed neither solid component nor thickness of the septae in the cystic lesion. Consequently, we performed distal pancreatectomy with splenectomy under the diagnosis of cystic neoplasia of the pancreas. Histopathologically, the cystic lesion showed two distinct component: an inner epithelial layer and an outer densely cellular ovarian-type stromal layer. Based on these findings, the cystic lesion was diagnosed as MCN.

    2018-03-20

    We characterize and apply the modified Bosniak classification system to a cohort of children with cystic renal lesions and known surgical pathology. We identified all patients at our institution with cystic renal masses who also underwent surgery for these lesions. Patients without available preoperative imaging or pathology were excluded. All radiological imaging was independently reviewed by a pediatric radiologist blinded to pathological findings. Imaging characteristics (size, border, septations, calcifications, solid components, vascularity) were recorded from the most recent preoperative ultrasounds and computerized tomograms. The modified Bosniak classification system was applied to these scans and then correlated with final pathology. A total of 22 patients met study criteria. Median age at surgery was 6.1 years (range 11 months to 16.8 years). Of the patients 12 (54.5%) underwent open nephrectomy, 6 (27.3%) open partial nephrectomy, 2 (9.1%) laparoscopic cyst decortication, 1 (4.5%) open renal biopsy and 1 (4.5%) laparoscopic partial nephrectomy. Final pathology was benign in 9 cases (41%), intermediate in 6 (27%) and malignant in 7 (32%). All malignant lesions were modified Bosniak class 4, all intermediate lesions were modified class 3 or 4 and 8 of 9 benign lesions (89%) were modified class 1 or 2. Cystic renal lesions in children with a modified Bosniak class of 1 or 2 were most often benign, while class 3 or 4 lesions warranted surgical excision since more than 90% of masses harbored intermediate or malignant pathology. The modified Bosniak classification system appears to allow for a reasonable clinical risk stratification of pediatric cystic renal masses.

    Full Text Available Objective: To observe the protective effect of Nigella sativa on number of cystic follicles in Letrozole induced polycystic ovaries in mice. Study Design: Laboratory based randomized control trial. Place and Duration of Study: Department of Anatomy, Army Medical College in collaboration with National Institute of Health from Nov 2014 to Nov 2015. Material and Methods: Forty female BALB/c mice were selected and divided in four groups, each having 10 animals. Group A served as control and was given normal diet. Group B was given Letrozole at a dose of 1milligram/kilogram body weight. Group C was treated with Letrozole for eight weeks at a dose of 1milligram/kilogram body weight and Nigella sativa seeds powder at a dose of 10grams/kilogram body weight once daily starting at 22 day and continued up to eight weeks. Group D was treated with Letrozole for eight weeks at a dose of 1milligram/kilogram body weight and Nigella sativa oil at a dose of 4milliliter/kilogram body weight once daily starting at 22 day and continued up to eight weeks. Animals were dissected a day after last dose. Size, shape, color and consistency of ovary was observed. Right ovary was processed, embedded and stained for histological study. Number of cystic follicles were counted and noted. Results: Significant number of cystic follicles was observed in ovaries of animals of group B as compared to group A. While their number decreased significantly in group C and D as compared to group B. Conclusion: Nigella sativa seeds powder and its oil, both have a similar protective effect on histomorphology of ovary of polycystic ovarian syndrome (PCOS in mice by decreasing the number of cystic follicles.

  6. Carcinoma gallbladder.

    Biswas, P K

    2010-07-01

    Carcinoma gallbladder (CaGb) is a rare disease. The aetiology of CaGb is yet not known. However the risk of CaGb is increased in anomalous pancreaticobiliary duct junction (APBDJ), gall stones, xanthogranulomatus cholecystitis, calcified or porcelain gallbladder, cholelithiasis with typhoid carriers, gallbladder adenoma, red meat consumption and tobacco uses. There are protective effects of vegetables on CaGb. Most of the cases present with advanced disease. In early carcinoma of a gallbladder sign and symptoms mimic benign disease. The diagnosis is established by ultrasonography, computerized tomography and guided fine needle aspiration cytology (FNAC). Biochemical tests are of very little value in making a diagnosis. The treatment depends on the clinical stage at presentation. Surgery offers the best chance of cure. In stage T1a, laparoscopic or open cholecystectomy alone is curative, and in T1b, cholecystectomy with hepatoduodenal lymph node dissection without combined resection of an adjacent organ is required. Segment S4a+5 hepatectomy combined with extrahepatic bile duct resection (BDR) and D2 lymph node dissection is a highly recommended operation for the treatment of T2 and T3 CaGb. The dye injection method is useful in determining the appropriate extent of hepatic resection for advanced CaGb. Resurgery is required only in those cases where tumour has invaded the serosa and/ or adjacent structures when diagnosed postoperatively. Biliary bypass is required for palliation. Prognosis depends on early diagnosis and appropriate surgical excision.

    Full Text Available Pulmonary infections in patients with cystic fibrosis (CF, are a major cause of morbidity and mortality. Prevention, diagnosis and therapy in cystic fibrosis, lead to the necessary collaboration between clinical and laboratory to identify effective strategies and appropriate solutions to address the problems inherent isolation micro-organisms, antibiotic strategies, overcoming of bacterial resistance and other problems management of these patients. The task of the microbiology laboratory and research in quickly and accurately, the agents responsible for these infectious processes, in order to isolate them from material, identify and determine their sensitivity antibiotics. A microbiological surveillance on 34 patients (13 males and 21 females with CF and related to the “Support Services Provincial Trento for the treatment of cystic fibrosis “in the period July 2005 - August 2008, was carried out. 180 Gram positive and 278 of Gram negative bacteria as well as 235 fungi wre collected. Staphylococcus aureus was the most frequently organism found in patients with CF with an incidence of 23% on 156 strains isolated, Pseudomonas aeruginosa was collected 19% of all microorganisms isolated corresponding to 131 strains, Candida albicans is the yeast often isolated with a frequency 22% equal to 149 isolates, Aspergillus fumigatus was isolated at a rate of 8%. From the data we collected and processed has been noted that the local epidemiology of CF patients reflects as reported in the scientific literature and national international consulting, both as a type microorganisms that frequency also isolated compared to age groups. Considering the score of Bartlett as discriminating respiratory fitness of the material, it has been observed that only 32 samples over 327 total (10% would materials insignificant.

    2011-02-01

    Full Text Available OBJECTIVE: To assess whether the cystic craniopharyngiomas can be controlled with the use of intratumoral applications of interferon alpha. METHOD: Nineteen patients with the diagnosis of cystic craniopharyngioma were treated with intratumoral chemotherapy with interferon alpha from January 2002 to April 2006. All patients underwent placement of an intracystic catheter connected to an Ommaya reservoir. Through this reservoir were made applications during chemotherapy cycles. Each cycle corresponded to application of 3,000,000 units of interferon alpha three times per week on alternate days totalizing 36,000,000 units. Response to treatment was evaluated by calculating the tumor volume on MRI control after one, three and six months after the end of each cycle. Patients who developed worsening of symptoms or who had insignificant reduction in tumor volume during follow-up underwent repeat cycle chemotherapy. RESULTS: Four patients received four cycles of chemotherapy, three patients received three cycles, six patients received two cycles and six patients received one. The lower percentage of reduction in tumor volume was 60% and the bigger reduction was 98.37%. Eleven patients had a reduction greater than 90%. Five patients had a tumor reduction between 75 and 90% and in three patients the tumors were reduced by less than 75%. No deaths occurred during treatment and side effects of interferon alpha were well tolerated. No treatment was discontinued. Follow-up after the last application ranged from one year and five months to three years and nine months. CONCLUSION: The intratumoral chemotherapy with interferon alpha decreases the volume of cystic craniopharyngiomas and so far can be considered a new therapeutic alternative.

    Even though laparoscopic cholecystectomy (LC) emerged over 20 years ago, controversies persist with regard to the best method to ligate the cystic duct and artery. We proposed to assess the effectiveness and safety of electrocoagulation to seal the cystic artery and cystic duct after their occlusion with only one absorbable clip. We retrospectively compared the clinical data for 635 patients undergoing LC using electrocoagulation to seal the cystic artery and cystic duct that were occluded with only one absorbable clip (Group 1) and 728 patients undergoing LC using titanium clips (Group 2). In parallel, 30 rabbits randomized into six groups underwent cholecystectomy. After cystic duct ligation with absorbable or titanium clips, the animals were sacrificed 1, 3, or 6 months later, and intraabdominal adhesions were assessed after celiotomy. The mean operative time was significantly shorter (41.6 versus 58.9 minutes, PElectrocoagulation of the cystic artery and cystic duct that were occluded with only one absorbable clip is safe and effective during LC. This approach is associated with shortened operative times and reduced leakage, compared with the standard method using metal clips.

    2017-08-22

    Cystic fibrosis is a genetic disorder which can lead to multiorgan dysfunction. Malabsorption of fat and fat-soluble vitamins (A, D, E, K) may occur and can cause subclinical deficiencies of some of these vitamins. Vitamin K is known to play an important role in both blood coagulation and bone formation. Supplementation with vitamin K appears to be one way of addressing the deficiency, but there is very limited agreement on the appropriate dose and frequency of use of these supplements. This is an updated version of the review. To assess the effects of vitamin K supplementation in people with cystic fibrosis and to determine the optimal dose and route of administration of vitamin K for both routine and therapeutic use. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Most recent search: 30 January 2017. Randomised and quasi-randomised controlled trials of all preparations of vitamin K used as a supplement compared to either no supplementation (or placebo) at any dose or route and for any duration, in children or adults diagnosed with cystic fibrosis (by sweat test or genetic testing). Two authors independently screened papers, extracted trial details and assessed their risk of bias. Two trials (total of 32 participants) each lasting one month were included in the review and were assessed as having a moderate risk of bias. One was a dose-ranging parallel group trial in children (aged 8 to 18 years); and the other (with an older cohort) had a cross-over design comparing supplements to no treatment, but no separate data were reported for the first intervention period. Neither of the trials addressed any of the primary outcomes (coagulation, bone formation and quality of life). Both trials reported the restoration of serum vitamin K and undercarboxylated osteocalcin

    Full Text Available Benign cystic mesothelioma (BCM is a rare benign disease that forms multicystic masses in the abdomen, pelvis, and retroperitoneum. It occurs predominantly in young to middle-aged women. The majority of cases were associated with a history of abdominal or pelvic operation, a history of endometriosis, and pelvic inflammatory disease. We present a unique case of BCM which is different to the previous cases. The patient was a 52-year-old man showing features of peritoneal carcinomatosis accompanied by ascites on abdominal computed tomography scans. We herein report a case of BCM misdiagnosed with peritoneal carcinomatosis.

    2007-01-01

    Over the past 20 years, there has been tremendous progress in the area of patient-reported outcomes (PROs). A PRO instrument is defined as any measure of a patient's health status that is elicited directly from the patient and assesses how the patient “feels or functions with respect to his or her health condition.” The advances seen in clinical research regarding PROs has been mirrored in research in cystic fibrosis (CF). A large number of instruments have been used for both therapeutic and ...

    Intestinal volvulus is a life-threatening emergency requiring prompt surgical management. Prenatal intestinal volvulus is rare, and most are secondary to intestinal atresia, mesenteric defect or without any underlying cause. Cystic fibrosis (CF) is known to cause digestive tract disorders. After birth, 10-15% of newborns with CF may develop intestinal obstruction within a few days of birth because of meconial ileus. 1 This obstruction is a result of dehydrated thickened meconium obstructing the intestinal lumen. We report two cases of fetuses with prenatal diagnosis of segmental volvulus in whom CF was diagnosed. 2016 BMJ Publishing Group Ltd.

    Cystic fibrosis, the most common inherited disease of white population, is a disease of CFTR channels, in which mucosal function of many organs especially respiratory tract is impaired. Decreased mucociliary clearance and accumulation of mucus in airways facilitates colonization of infectious microorganisms, followed by infection. Following chronic infection, persistent inflammation ensues, which results in airway remodeling and deterioration of mucociliary clearance and result in a vicious cycle. Here, it is hypothesized that cholera toxin (CT) could ameliorate symptoms of cystic fibrosis as CT could dilute the thickened mucus, improve mucociliary clearance and alleviate airway obstruction. CT strengthens immunity of airway mucosa and it could attenuates bacterial growth and reduce persistency of infection. CT also modulates cellular immune response and it could decrease airway inflammation, hinder airway remodeling and prevent respiratory deterioration. Thereby it is hypothesized that CT could target and ameliorate many of pathophysiologic steps of the disease and it explores new horizons in treatment of CF. Copyright © 2015 Elsevier Ltd.

    Lobular carcinoma in situ (LCIS) is a known risk factor for invasive breast carcinoma, but there is increasing data indicating a possible precursor relationship. This study investigates the incidence of lobular carcinoma in situ that occurs with invasive lobular carcinoma (ILC). Women diagnosed with ILC or LCIS from 2000 to 2010 were retrospectively identified and reviewed after institutional review board approval. This group was divided into two cohorts: ILC alone, and LCIS and ILC (ILC/LCIS). Patient demographics, disease characteristics, and treatment modalities were captured. p invasive ductal carcinoma at ∼40%. The association of pre-invasive and invasive lobular lesions should be further studied in a large scale prospective study to assess for a precursor relationship. Copyright © 2014 Elsevier Ltd.

    Bringing new therapies to patients with rare diseases depends in part on optimizing clinical trial conduct through efficient study start-up processes and rapid enrollment. Suboptimal execution of clinical trials in academic medical centers not only results in high cost to institutions and sponsors, but also delays the availability of new therapies. Addressing the factors that contribute to poor outcomes requires novel, systematic approaches tailored to the institution and disease under study. To use clinical trial performance metrics data analysis to select high-performing cystic fibrosis (CF) clinical research teams and then identify factors contributing to their success. Mixed-methods research, including semi-structured qualitative interviews of high-performing research teams. CF research teams at nine clinical centers from the CF Foundation Therapeutics Development Network. Survey of site characteristics, direct observation of team meetings and facilities, and semi-structured interviews with clinical research team members and institutional program managers and leaders in clinical research. Critical success factors noted at all nine high-performing centers were: 1) strong leadership, 2) established and effective communication within the research team and with the clinical care team, and 3) adequate staff. Other frequent characteristics included a mature culture of research, customer service orientation in interactions with study participants, shared efficient processes, continuous process improvement activities, and a businesslike approach to clinical research. Clinical research metrics allowed identification of high-performing clinical research teams. Site visits identified several critical factors leading to highly successful teams that may help other clinical research teams improve clinical trial performance.

    Renal cystic lesions are usually diagnosed in the radiologists' practice and therefore their characterization is crucial to determine the clinical approach to be adopted and prognosis. The Bosniak classification based on computed tomography findings has allowed for standardization and categorization of lesions in increasing order of malignancy (I, II, IIF, III and IV) in a simple and accurate way. The present iconographic essay developed with multidetector computed tomography images of selected cases from the archives of the authors' institution, is aimed at describing imaging findings that can help in the diagnosis of renal cysts.

    Nevoid basal cell carcinoma syndrome (NBCCS) is rare in black persons. We describe an 11-year-old black boy with NBCCS who presented with exotropia and a painful, expanding, cystic mass in the left posterior alveolar ridge. Further examination revealed odontogenic keratocysts with palmar and plantar pitting. Less than 5% of reported patients with NBCCS are black. To our knowledge, this is the first report of a black patient with NBCCS presenting with exotropia and an impacted molar displaced into the orbit by an odontogenic keratocyst.

    Background and Purpose: In a retrospective study the role of radiation therapy for the treatment of primary tracheal carcinoma was investigated. Patients and Methods: Between 1984 and 1997, 25 patients with primary tracheal carcinoma were treated with external beam radiotherapy (17 squamous-cell carcinoma [SCC], 8 adenoid cystic carcinoma [ACC], median dose SCC 60 Gy, ACC 55 Gy). An additional brachytherapy boost was carried out in 10/25 patients (median dose SCC 18 Gy, ACC 15 Gy). Ten patients underwent operative treatment. Results: The median survival (Kaplan-Meier) for patients with SCC was 33 months (ACC 94.2). The 1-, 2- and 5-year survival rates (Kaplan-Meier) for patients with SCC were 64.7% (ACC 85.7%), 64.7% (ACC 85.7%), and 26% (ACC 85.7%). Patients with ACC and patients with a complete remission after treatment had a significantly better survival probability (log rank test, p [de

    From June 1993 through October 1996, nineteen oropharynx cancer patients (squamous cell carcinoma T1; 1, T2; 10, T3; 6, T4; 1, and adenocarcinoma T2; 1) were treated with high dose rate interstitial radiotherapy combined with moderate external radiotherapy. Fourteen patients (T1; 1, T2; 10 and T3; 3) were controlled locally and five patients (T3; 3, T4; 1 and adenocarcinoma; 1) were not. Temporary soft tissue necrosis were experienced among four patients. With short follow-up period xerostomia and dysgeusia were less than definitive external radiotherapy as clinical impression. In addition with markedly increased tumor dose the local control rate can be improved. This treatment method can be an alternative to definitive external radiotherapy to gain better QOL and higher control rate. (author)

    The purpose of this article is to report the outcome of neoadjuvant radiochemotherapy (N-RCT) + surgery in patients with squamous cell carcinoma of the esophagus at a single institution. We retrospectively reviewed data from patients who were referred to our department for N-RCT. From 1988-2011, 103 patients were treated with N-RCT with cisplatin and/or 5-fluorouracil (5-FU). Group 1: (n = 55) from 1988-2006 with 39.6-40 Gy and 5-FU with (n = 17) or without cisplatin (n = 38). Group 2: from 2003-2010 with 44-45 Gy and 5-FU with (n = 40) or without cisplatin (n = 8). All patients underwent radical resection with reconstruction according to tumor location and 2-field lymph node dissection. The degree of histomorphologic regression was defined as grade 1a (pCR, 0 % residual tumor), grade 1b (pSTR, < 10 % residual tumor), grade 2 (10-50 % residual tumor), and grade 3 (> 50 % residual tumor). Median follow-up time from the start of N-RCT was 100 months (range 2-213 months). The median overall survival (OS) for the whole cohort was 42 months and the 5-year OS was 45 ± 5 %. In the multivariate analysis, worse ECOG performance status (p < 0.001), weight loss > 10 % before the start of the N-RCT (p = 0.025), higher pT category (p = 0.001), and grade 2/3 pathologic remission (p < 0.001) were significantly associated with a poor OS. PCR and pSTR rates for group 1 were 36 % and 18 % compared to 53 % and 22 % for group 2 (p = 0.011). There was a tendency for a better outcome in group 2 patients without statistical significance. The 5-year OS, disease-free survival and recurrent-free survival were 36 ± 7 %, 35 ± 6, and 36 ± 7 % for group 1 and 55 ± 7, 49 ± 7, and 53 ± 7 in group 2 (p = 0.117, p = 0.124, and p = 0.087). There was no significant difference between the two groups considering the postoperative morbidity and mortality. Higher radiation doses and more use of simultaneous cisplatin lead to higher pathologic response rates to N-RCT and may be associated with

  10. Genetic basis of calcifying cystic odontogenic tumors.

    Directory of Open Access Journals (Sweden)

    Akane Yukimori

    Full Text Available Calcifying cystic odontogenic tumors (CCOTs are benign cystic tumors that form abnormally keratinized ghost cells. Mutations in CTNNB1, which encodes beta-catenin, have been implicated in the development of these tumors, but a causal relationship has not been definitively established. Thus, mutational hot spots in 50 cancer genes were examined by targeted next-generation sequencing in 11 samples of CCOT. Mutations in CTNNB1, but not in other genes, were observed in 10 of 11 cases. These mutations constitutively activate beta-catenin signaling by abolishing the phosphorylation sites Asp32, Ser33, or Ser37, and are similar to those reported in pilomatrixoma and adamantinomatous craniopharyngioma. In contrast, BRAF or NRAS mutations were observed in 12 and two control samples of ameloblastoma, respectively. In HEK293 cells, overexpression of mutated CTNNB1 also upregulated hair keratin, a marker of ghost cells. Furthermore, ghost cells were present in two cases of ameloblastoma with BRAF and CTNNB1 mutations, indicating that ghost cells form due to mutations in CTNNB1. The data suggest that mutations in CTNNB1 are the major driver mutations of CCOT, and that CCOT is the genetic analog of pilomatrixoma and adamantinomatous craniopharyngioma in odontogenic tissue.

    Full Text Available Cystic fibrosis (CF is a multisystem disease with a range of abdominal manifestations including those involving the liver, pancreas, and kidneys. Recent advances in management of the respiratory complications of the disease has led to a greater life expectancy in patients with CF. Subsequently, there is increasing focus on the impact of abdominal disease on quality of life and survival. Liver cirrhosis is the most important extrapulmonary cause of death in CF, yet significant challenges remain in the diagnosis of CF related liver disease. The capacity to predict those patients at risk of developing cirrhosis remains a significant challenge. We review representative abdominal imaging findings in patients with CF selected from the records of two academic health centres, with a view to increasing familiarity with the abdominal manifestations of the disease. We review their presentation and expected imaging findings, with a focus on the challenges facing diagnosis of the hepatic manifestations of the disease. An increased familiarity with these abdominal manifestations will facilitate timely diagnosis and management, which is paramount to further improving outcomes for patients with cystic fibrosis.

    Stereotaxic intracavitary irradiation with instillation of phosphorus-32 ( 32 P) colloidal chromic phosphate was performed in nine patients with cystic craniopharyngiomas. Serial neurological, ophthalmological, neuroendocrinological, and radiological examinations were performed before and after treatment. Dosimetry was determined based on a computerized tomography (CT) estimation of tumor volume, and was calculated to provide a tumoricidal dose (200 to 300 Gy) to the cyst wall. The follow-up period ranged from 14 to 45 months (mean 27 months). After treatment, all nine patients showed improvement of symptoms and radiological evidence of cyst regression. Because of an expanding solid component producing recurrent symptoms, one patient required a craniotomy 14 months after isotope instillation. Three of five patients with impaired visual acuity before surgery had significant improvement in acuity after treatment. Preoperative visual field defects in eight patients improved in four after 32 P therapy. Of seven patients with preoperative endocrine abnormalities, one individual showed almost complete normalization and another had improvement in endocrine function. Patients who exhibited residual neuroendocrine function before isotope instillation developed no significant deterioration in endocrine status during the follow-up period. The findings suggest that stereotaxic intracavitary irradiation is a safe and effective treatment which should be considered as the initial surgery for cystic craniopharyngiomas

    To understand variation in the aetiology, microbiology and burden of bronchiectasis and cystic fibrosis across different global healthcare systems.; Bronchiectasis is the term used to refer to dilatation of the bronchi that is usually permanent and is associated with a clinical syndrome of cough, sputum production and recurrent respiratory infections. It can be caused by a range of inherited and acquired disorders, or may be idiopathic in nature. The most well recognised inherited disorder in Western countries is cystic fibrosis (CF, an autosomal recessive condition that leads to progressive bronchiectasis, bacterial infection and premature mortality. Both bronchiectasis due to CF and bronchiectasis due to other conditions are placing an increasing burden on healthcare systems internationally. Treatments for CF are becoming more effective leading to more adult patients with complex healthcare needs. Bronchiectasis not due to CF is becoming increasingly recognised, particularly in the elderly population. Recognition is important and can lead to identification of the underlying cause, appropriate treatment and improved quality of life. The disease is highly diverse in its presentation, requiring all respiratory physicians to have knowledge of the different “bronchiectasis syndromes”. The most common aetiologies and presenting syndromes vary depending on geography, with nontuberculous mycobacterial disease predominating in some parts of North America, post-infectious and idiopathic disease predominating in Western Europe, and post-tuberculosis bronchiectasis dominating in South Asia and Eastern Europe. Ongoing global collaborative studies will greatly advance our understanding of the international impact of bronchiectasis and CF.

    Chaaban, Mohamad R.; Kejner, Alexandra; Rowe, Steven M.

    2013-01-01

    Background: Advances in the care of patients with cystic fibrosis (CF) have improved pulmonary outcomes and survival. In addition, rapid developments regarding the underlying genetic and molecular basis of the disease have led to numerous novel targets for treatment. However, clinical and basic scientific research focusing on therapeutic strategies for CF-associated chronic rhinosinusitis (CRS) lags behind the evidence-based approaches currently used for pulmonary disease. Methods: This review evaluates the available literature and provides an update concerning the pathophysiology, current treatment approaches, and future pharmaceutical tactics in the management of CRS in patients with CF. Results: Optimal medical and surgical strategies for CF CRS are lacking because of a dearth of well-performed clinical trials. Medical and surgical interventions are supported primarily by level 2 or 3 evidence and are aimed at improving clearance of mucus, infection, and inflammation. A number of novel therapeutics that target the basic defect in the cystic fibrosis transmembrane conductance regulator channel are currently under investigation. Ivacaftor, a corrector of the G551D mutation, was recently approved by the Food and Drug Administration. However, sinonasal outcomes using this and other novel drugs are pending. Conclusion: CRS is a lifelong disease in CF patients that can lead to substantial morbidity and decreased quality of life. A multidisciplinary approach will be necessary to develop consistent and evidence-based treatment paradigms. PMID:24119602

    2016-01-01

    Owing to evolution in treatment, the average life expectancy of patients with cystic fibrosis (CF) has increased. This has been followed by an increase in urological complications such as urinary incontinence. As stress incontinence occurs during exercise, it may have a negative effect on the implementation of respiratory physiotherapy. The purpose of this study is to determine the prevalence of urinary incontinence and its effect on the quality of life and physiotherapy in a population with CF. Questionnaires were used to determine the prevalence of incontinence in patients of the Cystic Fibrosis Clinic of the University Hospital in Brussels. Two different surveys were used, depending on the age of the patients (incontinence were emphasized. Questionnaires were completed by 122 participants aged 6-59 years, showing an overall prevalence of 27% for urinary incontinence. Mainly adults reported urinary incontinence, with a prevalence of 11% in men and 68% in women aged 12 and above. The amount of urinary leakage was usually only a few drops and it was mainly triggered by coughing. Many of the participants had never mentioned this symptom to anyone. Doctors' and physical therapists' attention should be drawn to the fact that urinary incontinence is part of the complication spectrum of CF. A quarter of the study population refrained from coughing up phlegm and from physiotherapy. It is important to actively question and inform about this problem, to enable its detection and treatment.

    2014-01-15

    Diffuse cystic lung disease represents a diverse group of uncommon disorders with characteristic appearance on high resolution CT imaging. The combination of imaging appearance with clinical features and genetic testing where appropriate permits a confident and accurate diagnosis in the majority of the diseases without recourse for open lung biopsy. The mechanism of cyst development disease is unclear but in some disorders appears to be related to small airways obstruction. These diseases are incurable, with the exception of Langerhans cell histiocytosis which may spontaneously remit or resolve on smoking cessation. Disease progression is unpredictable; in general older patients have a more benign disease, while young patients may progress rapidly to respiratory failure. An understanding of the complications of cystic lung disease and the appearance of disease progression is essential for the management of these patients. A number of these disorders are associated with malignancy, recognition of the potential tumors permits appropriate imaging surveillance. Due to the widespread use of CT, pulmonary cysts are increasingly discovered incidentally in an asymptomatic individual. The diagnostic challenge is to determine whether these cysts represent an early feature of a progressive disease or have no clinical significance. In the elderly population the cysts are unlikely to represent a progressive disease. In individuals <50 years further evaluation is recommended.

    A study was performed to assess the values of magnetic resonance (MR) imaging in evaluation and the follow up of patients with cystic periventricular leukomalacia. Ten patients selected for MR imaging were diagnosed as having periventricular cystic lesions based on US scans. The range of gestational ages was 27 to 32 weeks, and the range of birth weights was 927 to 2,046 g. Twenty MR examinations were carried out using a 0.5 T superconducting system (Resona; Yokogawa). On the first MR examinations, taken by 6 months of age, low signal intensity lesions within the periventricular white matter, moderate ventriculomegaly with irregularity of the ventricular wall and delayed myelination were observed. These were the MR findings observed in the subacute stage of PVL. On the second or the third MR examinations, taken after 12 months of age, increased signal intensity in periventricular white matter on T 2 weighted images decreased volume of periventricular white matter and centrum semiovale and the ventriculomagaly with irregularity of ventricular wall were observed. However, progressions of myelination were proved to be not delayed in comparison with age matched controls. These were thought to be the MR findings of late stage of PVL. As the US findings of PVL have good correlation with pathologic changes revealed at autopsy, MR imaging can depict myelination and detect PVL lesion beyond the neonatal period. These observations demonstrate the value of the MR imaging for the follow up of the patients with PVL beyond the time of fontanel closure. (author)

    Mammography has proven to be an effective modality for the detection of early breast carcinoma. However, 4-34 percent of breast cancers may be missed at mammography. Delayed diagnosis of breast carcinoma results in an unfavourable prognosis. The objective of this study was to determine the causes and characteristics of breast carcinomas missed by mammography at our institution, with the aim of reducing the rate of missed carcinoma. We reviewed the reports of 13,191 mammograms performed over a five-year period. Breast Imaging Reporting and Data Systems (BI-RADS) were used for the mammographical assessment, and reports were cross-referenced with the histological diagnosis of breast carcinoma. Causes of missed carcinomas were classified. Of 344 patients who had breast carcinoma and had mammograms done prior to surgery, 18 (5.2 percent) failed to be diagnosed by mammography. Of these, five were caused by dense breast parenchyma obscuring the lesions, 11 were due to perception and interpretation errors, and one each from unusual lesion characteristics and poor positioning. Several factors, including dense breast parenchyma obscuring a lesion, perception error, interpretation error, unusual lesion characteristics, and poor technique or positioning, are possible causes of missed breast cancers.

    Objective was to determine the utility of tissue harmonic imaging inevaluating cystic renal lesions and to compare these findings withconventional ultrasound guidance (USG) and CT. Thirty patients, detected withcystic renal lesions on routine USG (over a period of 18 months from July2004 to December 2005) at the Postgraduate Institute of Medical Education andResearch Chandigarh, Chandigarh, India) were included in this study. Allpatients underwent a conventional gray scale ultrasound study (GSI), followedby tissue harmonic imaging (THI) sonography on the same machine (advancetechnology limited high definition imaging 5000). Computed tomography ofabdomen was carried out within one week of the ultrasound examinations. Allimages were evaluated for size, number and location of lesions. The findingsof THI sonography, conventional USG and CT of abdomen were recorded in theirrespective proformas. The images obtained by GSI, THI and contrast enhancedCT were also evaluated for image, quality, lesion conspicuity and fluid-soliddifferentiation. Tissue harmonic imaging showed better image quality in 27 of34 lesions, improvement in lesion conspicuity was found in 27 of 34 cysticlesions and an improved solid-fluid differentiation in 30 of 34 lesions whencompared to GSI. The THI provided additional information as compared to GSIin 8 patients. The grading of CT scan was significantly higher in overallimage quality (p=0.007) and lesion conspicuity (p=0.004), but wasnon-significant for fluid-solid differentiation (p=0.23). Tissue harmonicimaging provides better image quality, lesion delineation and superiorcharacterization than conventional gray scale sonography. (author)

    Recognition of the congenital cystic masses of the face and neck is important because they are usually benign, and can be completely cured by surgical excision. We retrospective analyzed CT scan of 18 surgically proven congenital cystic masses of the face and neck. The cases included 5 thyroglossal duct cysts, 4 cystic hygromas, 5 dermoid cysts, 1 branchial cleft cyst, and 3 fissural cysts of the face. Of five cases of thyroglossal duct cysts, CT showed either a well-marginated, rim enhancing unilocular cystic mass (n=3), or a diffuse but heterogeneous highly enhancing soft tissue mass (n=2). The latter two cases were confirmed later as infected thyroglossal duct cysts. Four cases of cystic hygromas were seen as either an irregularly-marginated (n=3) or a well-marginated (n=1) rim enhancing multiseptated cystic mass with a fluid-fluid level. Five cases of dermoid cysts appeared as well-marginated rim enhancing unilocular ovoid masses. The content of each mass was predominantly fluid in four cases, of which additional solid components were found in two, and interspersed fat globules in one. One case was composed of a homogeneous fatty density. One case of branchial cleft cyst was in the anterior triangle near the left mandibular angle, and appeared as a well-marginated enhancing cystic mass with a thick rim. In this case displacement of the adjacent structures was noted also. All three cases of fissural cysts of the face were seen as a well-marginated, rim enhancing cystic mass, causing a smooth pressure erosion of the adjacent bones. We conclude that CT is useful for the evaluation of the congenital cystic masses of the face and neck, because it can differentiate various forms of the congenital lesions and is able to clearly reveal the relation of the mass to the adjacent structures

    Full Text Available Cystic meningioma is a relatively rare condition, radiological appearance of the cystic-solid components of the mass may create a diagnostic dilemma. The presence of a cyst is not a common imaging feature and this makes it difficult to differentiate it from hemangioblastoma, craniopharyngioma, metastasis and gliomas. Cystic meningiomas are present more commonly in children. We present a 60 year old male who presented with seizures and frontal lobe signs. The lesion was suspected as glioma however, postoperative histopathological examination demonstrated as meningioma. Patient showed remarkable recovery after surgery. Complete cyst resection should be considered if it is technically feasible and safe.

    Surgery has been the classic treatment of choice for benign cystic diseases, including lymphatic malformation, ranula, branchial cleft cyst, thyroglossal duct cyst, thyroid cyst, parathyroid cyst, and lymphocele. However, surgery is associated with a tendency toward recurrence and may be accompanied by various complications, such as nerve injuries, vascular injuries, and scar formation. Therefore, sclerotherapy using various agents has been applied successfully to treatment of benign cystic diseases in the neck. This editorial reviews the use of various sclerotic agents and application of sclerotherapy to benign cystic diseases in the neck.

    Five cystic mass lesions of the pancreas were exemined by MRI. Multiplocular fluid components were demonstrated as areas of various signal intensity in mucinous cystadenoma and cystadenocarcinoma. Gas within the cystic mass was noted in ductectatic mucinous cystadenocarcinoma. Honeycomb pattern and classification were not depicted in serous cystadenoma. Necrotic matter was demonstrated as area of lower signal than liver in pseudocyst. These results were then compared with CT and ultrasound and at present enhanced CT combined with ultrasound is more diagnostic than MRI for cystic mass lesions of the pancreas. (author)

    Cystic adventitial degeneration is a rare non-atherosclerotic cause of peripheral arterial occlusive disease, mainly seen in young men without other evidence of vascular disease. Diagnosis will be established by clinical findings and by ultrasound or angiography and can be treated by excision or enucleation of the affected arterial segment or by percutaneous ultrasound-guided aspiration. However, the etiology of adventitial cysts remains unknown. We report a case of cystic adventitial degeneration showing a connection between the joint capsule and the adventitial cyst, supporting the theory that cystic adventitial degeneration may represent ectopic ganglia from adjacent joint capsules.

    Quantitative immunoprecipitation and immunoradiometric assays have been developed for a protein present in the serum of cystic fibrosis homozygotes, and to a lesser extent in the serum of heterozygotes. When tested on a panel of sera from 14 cystic fibrosis patients, 29 heterozygotes and 23 controls, the immunoprecipitation assay allowed correct assignments to be made on 94% of occasions with one batch of antiserum and 95% with another. With the same panel of sera, the immunoradiometric assay allowed 94% correct assignments. It is suggested that such accuracy is the maximum that can be expected in the present state of knowledge of cystic fibrosis. (author)

    Laparoscopic surgical procedures are increasing in scope and in variety. The benefits of decreased wound morbidity and pain have been well documented for multiple procedures that have traditionally required laparotomy. Although there are few controlled studies to document them, these benefits may be evident from simple clinical observation. Cystic disease of the liver is a condition that is treated largely for symptomatic reasons. The so-called noninvasive or radiographic guided methods of treatment for cystic disease of the liver are fraught with high recurrence rates. We present four cases of cystic disease of the liver treated laparoscopically, followed with pertinent discussion.

    A case of a surgically confirmed cystic lymphangioma of the spleen is presented. Preoperative imaging consisted of US, contrast-enhanced CT and MRI, all showing a multiloculated lesion with small cystic cavities divided by thin septa, corresponding to dilated lymphatic spaces. Preoperative studies correlated well with the pathologic findings. Cystic lymphangioma of the spleen is a very rare condition and is usually solitary and asymptomatic. Large lymphangiomas may be an indication for splenectomy, since the risk of rupture is high even from minor abdominal trauma. Preoperative diagnosis may be achieved with correlated noninvasive imaging. (orig.)

    Surgical removal plays an important role in treating children's craniopharyngioma. For a safe and minimally invasive craniotomy, a reformed surgical modality was proposed in this paper by combining the insertion of an Ommaya reservoir system (ORS) by stereotactic puncture, aspiration of cystic fluid in 2-day interval for consecutive 7-10 days, and the delayed tumor resection. Eleven patients (aged from 5 to 9 years old) with giant cystic craniopharyngiomas who had undergone the reformed surgical modality during November 2014 and December 2015 were collected as group A. In contrast, seven patients (aged from 5 to 11 years old) who had undergone the traditional directed operation without any prior management from January 2014 to October 2014 were collected into group B. A retrospective analysis was performed for both groups at one institution. The preoperative and postoperative clinical presentations, neuroimaging, early postoperative outcome, and the surgery-related complications of both groups were reviewed. For group A, the mean value of the maximum tumor diameters shank from 52.36 to 23.82 mm after implementing aspiration of the cystic fluid in 1-day interval for consecutive 8.23 days. Eight patients (72.73%) in group A underwent a gross total resection (GTR), while two (28.57%) patients underwent GTR in group B. The postoperative electrolyte disturbance rate and endocrine disorder rate of group B were significantly higher than those of group A (42.86 vs 36.36%; 71.43 vs 45.45%). Postoperative long-term diabetes insipidus only occurred in one patient of group B, and postoperative visual deterioration occurred in two patients of group B. Besides, one patient of group B died of severe postoperative hypothalamus dysfunction. Patients with residual tumors were applied with additional adjuvant radiotherapy, and no recurrence was observed in follow-up examinations. A favorable outcome can be achieved by combining the insertion of an ORS by stereotactic puncture

    The imaging findings of two children with acinic cell carcinoma of the parotid gland are presented. Ultrasonic and computed tomography features are emphasized. One of these children, a 6 year old boy, suffers from the oculocerebrorenal syndrome of Lowe, a rare congenital, inherited condition manifested by defects of the nervous system (mental retardation, hypotonia), eyes (cataracts, glaucoma) and kidneys. To date, no known association exists between these two rare entities. The other child, a 10 year old girl, was otherwise well. The ultrasound findings of both cases demonstrate features more classic for a benign intraparotid mass than for a potentially malignant lesion. The possibility of acinic cell carcinoma should be considered if a well-defined, relatively homogeneously hypo-echoic intraparotid mass is encountered in a child, especially if cystic spaces are present. It was estimated that computed tomography findings reflected features already demonstrated by ultrasound and added little to characterization of the primary mass in this case. 12 refs.,5 figs.

    Full Text Available An extra-adrenal pheochromocytoma is also known as a paraganglioma. We are reporting the case of a 68-year-old female patient with an extremely rare primary nonfunctioning hepatic paraganglioma without any clinical signs and symptoms. A CECT scan of whole abdomen was done which showed a huge well defined peripherally enhancing fluid density cystic lesion measuring 14 cm × 14 cm × 12 cm with internal enhancing septations and few foci of calcification involving V to VIII segments of right lobe of liver which was compressing and displacing portal vein, its right branch, common bile duct, gall bladder. Mass was also compressing and displacing right kidney inferiorly. Laparotomy was done and sample of cyst wall sent for histopathology. After immunohistochemistry a diagnosis of paraganglioma was confirmed.

  17. Diabetes mellitus in childhood cystic fibrosis.

    Since 1984, five patients in the cystic fibrosis (CF) clinic at Cork Regional Hospital have developed diabetes mellitus (DM) and were treated with Insulin. None had received systemic corticosteroids but two had high calorie naso-gastric feeding regimes. Two died from lung disease. A fifteen year old boy developed bilateral cataracts. In nine other paediatric CF clinics in the Republic of Ireland (total: 420 patients), three patients have DM, two receiving Insulin. Abnormal glucose tolerance is becoming more common in CF as patients survive longer. The possible role of corticosteroid treatment and intensive carbohydrate feeding regimes in development of glucose intolerance must be considered. DM in CF differs from the usual childhood DM. Regular screening and early Insulin supplementation may be beneficial.

    Poly Cystic Ovarian Syndrome (PCOS) is one of the most common metabolic and reproductive disorders among women of reproductive age. Women suffering from PCOS present with a constellation of symptoms associated with menstrual dysfunction and androgen excess, which significantly impacts their quality of life. They may be at increased risk of multiple morbidities, including obesity, insulin resistance, type II diabetes mellitus, cardiovascular disease (CVD), infertility, cancer, and psychological disorders. This review summarizes what the literature has so far provided from guidelines to diagnosis of PCOS. It will also present a general overview about the morbidities associated with this disease, specifically with its more severe classic form. Finally, the review will stress on the various aspects of treatment and screening recommendations currently used in the management of this condition. PMID:27092084

    The persistence of chronic Pseudomonas aeruginosa lung infections in cystic fibrosis (CF) patients is due to biofilm-growing mucoid (alginate-producing) strains. A biofilm is a structured consortium of bacteria, embedded in a self-produced polymer matrix consisting of polysaccharide, protein...... and DNA. In CF lungs, the polysaccharide alginate is the major part of the P. aeruginosa biofilm matrix. Bacterial biofilms cause chronic infections because they show increased tolerance to antibiotics and resist phagocytosis, as well as other components of the innate and the adaptive immune system....... As a consequence, a pronounced antibody response develops, leading to immune complex-mediated chronic inflammation, dominated by polymorphonuclear leukocytes. The chronic inflammation is the major cause of the lung tissue damage in CF. Biofilm growth in CF lungs is associated with an increased frequency...
