BACKGROUND: Fine-needle aspiration (FNA) cytology is well accepted as a safe, reliable, minimally invasive, and cost-effective method for the diagnosis of salivary gland lesions. Salivary gland neoplasms are often difficult to diagnose because of morphologic heterogeneity and a variety of epithelial metaplastic changes. Hence, a number of salivary gland FNA specimens yield indeterminate results. For indeterminate FNA specimens, the suspicious-for-malignancy (SFM) category is used when a specific neoplasm falls short in quantity or quality for the criteria for malignancy...

Previous studies have reported that inhibitor of DNA binding 1 (ID1) exerts an oncogenic role in a number of tumors. In the present study, the role of ID1 in the growth, invasion and migration of salivary adenoid cystic carcinoma (SACC) cells was investigated. ID1 expression in clinical SACC samples was compared with that in normal salivary tissues using immunohistochemical staining, and the correlation between ID1 expression and clinical pathological characteristics was then determined. Subsequently, ID1 was overexpressed or silenced to investigate the effects of ID1 expression on SACC cell proliferation, invasion and migration...

INTRODUCTION: Whole body PET CT is an important investigation tool in malignancy patients and helps in ascertaining the metabolic activity and exact stage of the disease. However, like any other investigation, false positive results do exist and certain diseases other than cancer may show increased uptake. Hence, a careful evaluation of PET CT and clinical correlation in malignancy patients is a must to accomplish the suitable treatment. METHODS: In this retrospective observational study, seven cases of cancer with concomitant tuberculosis were included...

Prostate-specific membrane antigen (PSMA), is a transmembrane glycoprotein that is highly expressed on prostate adenocarcinomas, exhibits only limited expression in benign and extra-prostatic tissues, and thus represents an ideal target for the diagnosis and management of prostate cancer. Since its discovery over 30 years ago, significant effort has been made to develop clinical technology targeting PSMA. The last 5 years have seen an explosion of development of new agents targeting PSMA for diagnostic and therapeutic use...

Salivary gland cancers are a complex group of tumours with variations in location, type and grade, all of which influence their biological behaviour. The understanding of salivary gland pathology has evolved at the molecular level in the last decade leading to identification of distinct entities, development of improved methods of diagnosis as well as identifying therapeutic targets for selected high-grade tumours. This article focuses on these advances and their impact on the management of primary salivary gland cancers...

Radioactive iodine therapy (RAIT) is one of the important treatment modalities in the management of differentiated thyroid cancer (DTC). RAIT with iodine-131 has long been used in the management of DTC for the ablation of residual thyroid or treatment of its metastases. Despite being reasonably safe, radioiodine therapy is not always without side effects. Even relatively low administered activities of RAIT used for remnant ablation have been associated with the more clinically significant side effects of sialadenitis, xerostomia, salivary gland pain and swelling, dry eyes, excessive tearing, or alterations in taste in as many as 25% of patients...

Oral cancer is a malignant neoplasm that occurs in the oral cavity. Squamous cell carcinoma accounts for over 90%of the oral cancers, and others include adenocarcinoma derived from minor salivary gland, sarcoma, malignant lymphoma and metastatic cancer. The number of oral cancer patients in Japan is about 3-times higher than the current number. Age-adjusted male-to-female ratio is 3:2, which is higher in males than in females. Of oral cancers, tongue carcinomas accounts is the most common and accounts for 40%of oral cancers...

BACKGROUND: Epithelial-mesenchymal transition (EMT) is a complicated process that has been implicated in cancer progression and metastasis as well as the formation of many tissues and organs. BTB/POZ domain-containing protein 7 (BTBD7) is reported to regulate transcriptional factors and involved in the process of invasion and metastasis of some malignant tumors. Additionally, our preliminary studies have confirmed that BTBD7 expression was significantly correlated with Slug expression and poor prognosis of primary salivary adenoid cystic carcinoma (SACC)...

Peri/post-operative antibiotic prophylaxis (POABP) has become standard practice for preventing surgical site infections (SSI) in head and neck cancer patients undergoing microvascular reconstruction, but few data exist on optimal POABP regimens. Current surgical prophylaxis guideline recommendations fail to account for the complexity of microvascular reconstruction relative to other head and neck procedures, specifically regarding wound classification and antibiotic duration. Selection of POABP spectrum is also controversial, and must balance the choice between too narrow, risking subsequent infection, or too broad, and possible unwanted effects (e...

BACKGROUND: The ability of thyroid follicular cells to take up iodine enables the use of radioactive iodine (RAI) for imaging and targeted killing of RAI-avid thyroid cancer following thyroidectomy. To facilitate identifying novel strategies to improve (131)I therapeutic efficacy for patients with RAI refractory disease, it is desired to optimize image acquisition and analysis for preclinical mouse models of thyroid cancer. METHODS: A customized mouse cradle was designed and used for microSPECT/CT image acquisition at 1 hour (t1) and 24 hours (t24) post injection of (123)I, which mainly reflect RAI influx/efflux equilibrium and RAI retention in the thyroid, respectively...
