    Stage IV circular hypopharyngeal cancer is a disease with poor long-term survival, and the only means of cure—surgery—is associated with high morbidity. All patients admitted with circular hypopharyngeal cancer and extension to the esophagus were enrolled in a multidisciplinary treatment protocol, including circular laryngopharyngoesophagectomy with tracheostomy, neck dissection, and pull-up of a fundus rotation gastric tube that was anastomosed to the oropharynx. Five weeks postoperatively high-dose radiotherapy (60 Gy) was given to the cervical region. Altogether, 18 qualifying patients were explored cervically, were found to have resectable lesions (i.e., without carotid artery infiltration), and were included in the protocol. After laryngopharyngoesophagectomy, an elongated gastric tube was pulled up to the oropharynx. The average distance bridged with the tube was 32±4 cm. No anastomotic leaks were found on postoperative Gastrografin swallow, and oral feeding was started between days 5 and 8. Patients were discharged with normal oral feeding on day 21 (±17 days). Diarrhea, postprandial fullness, and reflux resolved within 6 months postoperatively. Five patients died during the follow-up period of 42 months (range 3-63 months): three due to cardiac events 18 and 38 months postoperatively and two within 12 months with residual disease and tumor recurrence, respectively. The estimated 5-year survival was 60%. We concluded that an aggressive multidisciplinary approach including circular laryngopharyngoesophagectomy, neck dissection, and high-dose radiotherapy ascertains good long-term survival and good functional results in patients with advanced hypopharyngeal cancer when the intestinal continuity is reconstructed with a fundus rotation gastroplast

    Analysis of the clinical relevance of histological classification of benign epithelial salivary gland tumours

    IntroductionA vast increase in knowledge of numerous aspects of malignant salivary gland tumours has emerged during the last decade and, forseveral reasons, thishas not been the case in benign epithelial salivary gland tumours. We have performed a literature review to investigate whether an accurate histological diagnosis of the 11 different types of benign epithelial salivary gland tumours is correlated to any differences in their clinical behaviour.MethodsA search was performed for histological classifications, recurrence rates and risks for malignant transformation, treatment modalities, and prognosis of these tumours. The search was performed primarily through PubMed, Google Scholar, and all versions of WHO classifications since 1972, as well as numerous textbooks on salivary gland tumours/head and neck/pathology/oncology. A large number of archival salivary tumours were also reviewed histologically.ResultsPleomorphic adenomas carry a considerable risk (5-15%) for malignant transformation but, albeit to a much lesser degree, so do basal cell adenomas and Warthin tumours, while the other eight types virtually never develop into malignancy. Pleomorphic adenoma has a rather high risk for recurrence while recurrence occurs only occasionally in sialadenoma papilliferum, oncocytoma, canalicular adenoma, myoepithelioma and the membranous type of basal cell adenoma. Papillomas, lymphadenoma, sebaceous adenoma, cystadenoma, basal cell adenoma (solid, trabecular and tubular subtypes) very rarely, if ever, recur.ConclusionsA correct histopathological diagnosis of these tumours is necessary due to (1) preventing confusion with malignant salivary gland tumours; (2) only one (pleomorphic adenoma) has a considerable risk for malignant transformation, but all four histological types ofbasal cell adenoma canoccasionally develop into malignancy, as does Warthin tumour; (3) sialadenoma papilliferum, oncocytoma, canalicular adenoma, myoepithelioma and Warthin tumour only occasionally recur; while (4) intraductal and inverted papilloma, lymphadenoma, sebaceous adenoma, cystadenoma, basal cell adenoma (apart from the membranous type) virtually never recur. No biomarker was found to be relevant for predicting recurrence or potential malignant development. Guidelines for appropriate treatment strategies are given.info:eu-repo/semantics/publishedVersio

    The controversy in the management of the N0 neck for squamous cell carcinoma of the maxillary sinus

    Get PDF
    Squamous cell carcinoma (SCC) of the maxillary sinus is a relatively rare disease. As the reported incidence of regional metastasis varies widely, controversy exists as to whether or not the N0 classified neck should be treated electively. In this review, the data from published series are analyzed to decide on a recommendation of elective treatment of the neck in maxillary SCC. The published series consist of heterogeneous populations of different subsites of the paranasal sinuses, different histological types, different staging and treatment modalities used and different ways of reporting the results. These factors do not allow for recommendations based on high levels of evidence. Given this fact, the relatively high incidence rate of regional metastasis at presentation or in follow-up in the untreated N0 neck, and the relatively low toxicity of elective neck irradiation, such irradiation in SCC of the maxillary sinus should be considered

    Is There A Role for Limited Parotid Resections for Primary Malignant Parotid Tumors?

    Get PDF
    Background: Lateral or total parotidectomy are the standard surgical treatmentsfor malignant parotid tumors. However, some authors have proposed a more limited procedure.(2) Methods: We performed a review of the literature on this topic. Studies were included that metthe following criteria: malignant parotid tumors, information about the extent of surgical resection,treated with less than a complete lateral lobectomy, and information on local control and/or survival.Nine articles fulfilled the inclusion criteria. (3) Results: Eight of the nine series reported favorableresults for the more limited approaches. Most used them for small, mobile, low-grade cancers inthe lateral parotid lobe. Most authors have used a limited partial lateral lobectomy for a presumedbenign lesion. The remaining study analyzed pediatric patients treated with enucleation with poorlocal control. (4) Conclusions: There is weak evidence for recommending less extensive proceduresthan a lateral parotid lobectomy. In the unique case of a partial lateral parotidectomy performed fora tumor initially thought to be benign but pathologically proved to be malignant, close follow-upcan be recommended for low grade T1 that has been excised with free margins and does not haveadverse prognostic factors

    No full text
    OBJECTIVE: To analyze a series of carcinoma ex pleomorphic adenoma (CXPA) and to assess the diagnostic difficulties. STUDY DESIGN: The clinical presentation of 24 CXPAs was compared with 300 pleomorphic adenomas (PAs). Furthermore, pathohistological findings and follow-up results of CXPAs were evaluated. RESULTS: Eight of 24 (33%) CXPAs versus 41 of 300 (14%) PAs were localized in the deep lobe (P < 0.05). Forty-two percent of CXPAs versus 6 percent of PAs, respectively, were greater than 4 cm (P < 0.05). The sensitivity in detecting CXPA by fine-needle aspiration cytology (FNAC) was 47 percent. The tumor was known to be malignant preoperatively in 10 (42%) patients. Six of 24 (25%) patients with CXPA developed a tumor recurrence. The overall 5-year survival rate of CXPA was 76 percent. CONCLUSION: CXPAs are difficult to identify preoperatively. FNAC has a low accuracy and sensitivity. CXPAs versus PAs are significantly more frequently localized in the deep lobe and are significantly greater in size

    Pleomorphic adenoma of the parotid gland: histopathologic analysis of the capsular characteristics of 218 tumors

    No full text
    BACKGROUND: Histopathologic features of the capsule may have an impact on the recurrence rate of pleomorphic adenomas. METHODS: Retrospective (n = 154) and prospective (n = 64) histologic analysis of the capsular characteristics such as incompleteness, tumor penetration, pseudopodia, and satellite tumors of 218 pleomorphic adenomas. RESULTS: In 160 of the 218 (73%) pleomorphic adenomas, 1 or more capsular characteristics such as incomplete capsule (33%), capsule penetration (26%), pseudopodia (40%), and satellite nodules (13%) were detected. Incomplete capsule and satellite tumors were most frequently seen in the stroma-rich (myxoid) subtype. Capsular penetration and pseudopodia were significantly more common in the prospective group than in the retrospective group (p < .05/<.05). CONCLUSION: Pseudopodia and satellite tumors were more common than reported in the literature. If left in the surrounding salivary gland tissue at surgery, they can lead to recurrences of pleomorphic adenomas of the parotid gland
