• surgical
  • Early-stage low-grade malignant salivary gland tumors are usually curable by adequate surgical resection alone. (healthlinkbc.ca)
  • Large bulky tumors or high-grade tumors carry a poorer prognosis and may best be treated by surgical resection combined with postoperative radiation therapy. (healthlinkbc.ca)
  • Tumour is at surgical margins . (blogspot.com)
  • Conclusion: Magnetic resonance imaging especially done at higher tesla systems like 1.5T & 3T with the use of contrast and advanced sequences is highly useful in the evaluation of spinal tumors not only for diagnosis but for surgical planning also. (ijrhs.org)
  • The swollen masses of Küttner's tumor are generally painful, and patients are advised surgical resection (known as 'sialadenectomy') of a part or whole of the glandular tissue upon suspicion of possible malignancy. (wikipedia.org)
  • Overall, the mainstay of the treatment for salivary gland tumor is surgical resection. (wikipedia.org)
  • More detailed surgical technique and the support for additional adjuvant radiotherapy depends on whether the tumor is malignant or benign. (wikipedia.org)
  • Surgical treatment of parotid gland tumors is sometimes difficult, partly because of the anatomical relationship of the facial nerve and the parotid lodge, but also through the increased potential for postoperative relapse. (wikipedia.org)
  • Ductal
  • Abnormalities of the salivary gland ducts leading to excessive accumulation or retention of ductal secretions, which can excite chronic inflammations. (wikipedia.org)
  • Recurrent
  • 20 ][ Level of evidence: 3iiiDii ] Unresectable or recurrent tumors may respond to chemotherapy. (uni-bonn.de)
  • The most common subtype of malignant PA is CXPA which develops in primary or recurrent PA. (semanticscholar.org)
  • It is also helpful to consider the presenting symptoms in terms of either single or multi-gland involvement, and the type of swelling present (recurrent swelling, diffuse swelling or a well-defined lump - see table 1), as this information helps differentiation between the five diagnostic categories of disease. (pulsetoday.co.uk)
  • tissue
  • Perhaps the most widely used currently is that system proposed by the World Health Organization in 2004, which classifies salivary neoplasms as primary or secondary, benign or malignant, and also by tissue of origin. (wikipedia.org)
  • Superior soft tissue contrast is possible with MRI leading to better delineation between tumor and adjacent musculature, especially in the tongue and floor of mouth where relatively little fat is present between tissue planes. (ucsd.edu)
  • Eventual periductal and interlobular (inside the gland) sclerosis (replacement of regular tissue with hard connective tissue). (wikipedia.org)
  • Carcinoma is a term for malignant neoplasms derived from cells of epithelial lineage, and/or that exhibit cytological or tissue architectural features characteristically found in epithelial cells. (wikipedia.org)
  • Although it is "benign" the tumor is aneuploid, it can recur after resection, it invades normal adjacent tissue and distant metastases have been reported after long (+10 years) time intervals. (wikipedia.org)
  • The diagnosis of salivary gland tumors utilize both tissue sampling and radiographic studies. (wikipedia.org)
  • CT allows direct, bilateral visualization of the salivary gland tumor and provides information about overall dimension and tissue invasion. (wikipedia.org)
  • Diagnosis
  • Given the difficulties of a definitive pre-operative diagnosis, the clinical entity of Küttner's tumor has so far remained significantly under-reported and under-recognized. (wikipedia.org)
  • In recent times, armed with a better understanding of the occurrences and observable features of this condition, surgeons are increasingly depending upon pre-operative ultrasonography along with Fine-needle aspiration cytological (FNAC) examinations to make an accurate presumptive diagnosis, and according to one estimate, about 44% of patients undergoing submandibular resection are found to have this condition. (wikipedia.org)
  • neck
  • Salivary gland neoplasms make up 6% of all head and neck tumors. (medscape.com)
  • The usual clinical presentation of a salivary gland tumor is a progressive head and neck region mass, with quite variable pace from one patient to another, and clinical signs associated with tumor location and size. (renalandurologynews.com)
  • Salivary gland tumors make up about 5% of all head and neck neoplasms, and causation is largely unknown. (renalandurologynews.com)
  • There has been an association of these tumors with radiation exposure in Japan, after therapeutic head and neck radiotherapy, and in children treated with whole brain radiotherapy for acute lymphocytic leukemia. (renalandurologynews.com)
  • Imaging of the head and neck has developed significantly with the advent of CT and MR. These modalities greatly compliment the physical and endoscopic examinations by revealing possible blind areas, such as subtle extension of neoplasms from the lower face and/or salivary glands to deep spaces, nonpalpable adenopathy, bone marrow invasion, and distant metastasis. (ucsd.edu)
  • duct
  • The symptoms are unmistakable, with all the features of infection (swollen, red tender gland), and pus may be milked from the duct orifice. (pulsetoday.co.uk)
  • Several factors have been postulated: Formation of a hard salivary calculus or sialolith by accumulation of calcium salts in the duct of the salivary gland (a process known as Sialolithiasis). (wikipedia.org)
  • classification
  • Due to the diverse nature of salivary gland tumours, many different terms and classification systems have been used. (wikipedia.org)
  • The 2005 World Health Organization (WHO) classification of SGTs is complex and comprises 10 benign and 23 malignant entities of epithelial origin. (atlasgeneticsoncology.org)
  • However, since different forms of malignant tumors generally exhibit diverse genetic, biological, and clinical properties - including response to treatment - accurate classification of lung cancer cases are critical to assuring that patients with lung cancer receive optimum management. (wikipedia.org)
  • Clinical
  • Materials & Methods: Forty- nine patients who were admitted in the Dept. of Neurosurgery with clinical suspicion of spinal tumor were evaluated on a GE Medical System, Sigma 1.5 T, Sys # GEMSOW scanner. (ijrhs.org)
