OBJECTIVES: This study aimed to examine the radioprotective effect of vitamin E on salivary glands after radioactive iodine (I) therapy in patients with differentiated thyroid cancer. PATIENTS AND METHODS: Eighty-two patients with differentiated thyroid cancer were enrolled in this study. They were divided randomly into four groups (control group: 22 cases, group A: 23 cases, group B: 22 cases, and group C: 15 cases) before postsurgical ablation therapy with 100 mCi I...

OBJECTIVES: Mucoepidermoid carcinoma (MEC) is an uncommon malignancy that most commonly occurs in the parotid gland followed by the minor salivary glands of the upper aerodigestive tract, most notably in the oral cavity (OC) and oropharynx (OP). Because of its rarity, few studies have been performed that are specific to MEC within the OC and OP. The objective of this study is to describe the tumor characteristics and prognostic features for MEC of the OC and OP. MATERIALS AND METHODS: The National Cancer Database (NCDB) was used for this study...

PURPOSE: This study evaluates the performance and planning efficacy of the Auto-Planning (AP) module in the clinical version of Pinnacle 9.10 (Philips Radiation Oncology Systems, Fitchburg, WI, USA). METHODS AND MATERIALS: Twenty automated intensity-modulated radiotherapy (IMRT) plans were compared with the original manually planned clinical IMRT plans from patients with oropharyngeal cancer. RESULTS: Auto-Planning with IMRT offers similar coverage of the planning target volume as the original manually planned clinical plans, as well as better sparing of the contralateral parotid gland, contralateral submandibular gland, larynx, mandible, and brainstem...

Two patients diagnosed with advanced head and neck cancer were treated with cetuximab 400 mg/m(2) intravenously for one loading dose followed by 250 mg/m(2) IV on days 1, 8, and 15 along with paclitaxel 80 mg/m(2) and cisplatin 30 mg/m(2) intravenously on days 1 and 8 repeated every 21 days for three cycles (CPP). Maintenance cetuximab 250 mg/m(2) intravenously weekly was continued following the aforementioned regimen for one year or until disease progression. Patient A was diagnosed with squamous cell carcinoma of the parotid gland treated initially with parotidectomy and radiation therapy...

There is a steady rise in incidence of malignant salivary gland tumors in the United States, with mucoepidermoid carcinoma (MEC) the most frequent. Although 40% of MECs are found in the parotid gland, these lesions possess the capacity to develop anywhere along the aerodigestive tract. Here, we present a case of recurrent tongue MEC in a young adult female patient with history of lung malignancy and multiple brain metastases. Without a universally accepted management protocol for recurrent MECs, the current clinical practice uses tumor grade, location, and clinical progression to determine both prognosis and goals of care...

BACKGROUND AND PURPOSE: The aim is to determine the radiobiological parameters of four popular normal tissue complication probability (NTCP) models that describe the dose-response relations of salivary glands and pharyngeal constrictors to the severity of patient reported xerostomia and dysphagia, respectively 6 and 12months post chemo-radiotherapy, furthermore, to evaluate the goodness-of-fit of the NTCP models for different combinations of glands and constrictors. MATERIAL AND METHODS: Forty-three patients were treated on a prospective multi-institutional phase II study (ClinicalTrials...

Radioligand therapy (RLT) with Lu-177-labeled PSMA-ligands is a new therapy option for prostate cancer. Biodistribution in normal tissues is of interest for therapy planning. We evaluated if the biodistribution of Ga-68-PSMA-11 is influenced by tumor load. RESULTS: In patients with high tumor load, SUVmean was reduced to 61.5% in the lacrimal glands, to 56.6% in the parotid glands, to 63.7% in the submandibular glands, to 61.3% in the sublingual glands and to 55.4% in the kidneys (p < 0...

Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL), a member of the TNF superfamily, has garnered interest as it is relatively non-toxic to normal cells, but selectively induces apoptotic cell death in multiple types of transformed or malignant cells. Bufalin is the major digoxin-like immunoreactive component of Sum Su, which is obtained from the skin and parotid venom gland of the toad. Bufalin is known to inhibit cell proliferation and induce apoptosis in a variety of cancer cells. The present study investigated whether bufalin promoted TRAIL-induced apoptotic cell death...

BACKGROUND: The aim of this study was to investigate if the flattening filter free (FFF) irradiation mode of a linear accelerator (linac) is advantageous as compared to the flat beam (FF) irradiation mode in intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) for carcinoma of the hypopharynx / larynx. METHODS: Four treatment plans were created for each of 10 patients for an Elekta Synergy linac with Agility collimating device, a dual arc VMAT and a nine field step and shoot IMRT each with and without flattening filter...

BACKGROUND: Adaptive radiotherapy is being used in few institutions in patients with head and neck cancer having bulky disease using periodic computed tomography imaging accounting for volumetric changes in tumor volume and/or weight loss. Limited data are available on ART in the postoperative setting. We aim to identify parameters that would predict the need for ART in patients with head and neck cancer and whether ART should be applied in postoperative setting. MATERIALS AND METHODS: Twenty patients with stage III-IV head and neck cancer were prospectively accrued...

Primary epithelial tumours of the salivary glands are very rare in paediatric patients. The aim of this study was to evaluate the clinical course, treatment, and outcomes of these uncommon neoplasms based on the authors' experience and the recent literature. The medical charts of 12 female patients and seven male patients with primary epithelial salivary gland tumours were reviewed. All were under 19 years of age and underwent surgical treatment between 1994 and 2016. The results of this group of paediatric patients were compared with those of 621 adult patients...

The aim of this study was to evaluate the effects of the first radioactive iodine (I) therapy on functions of salivary glands in patients with differentiated thyroid carcinoma (DTC).There were 36 consented patients with DTC enrolled in this study, who received 3.7 GBq (100mCi) I for ablation after total thyroidectomy. Salivary gland function was assessed using salivary gland scintigraphy in two phases, one 4 hours before and the other 6 months after I therapy (both under thyrotropin stimulation condition)...

OBJECTIVES: The aberrant expression of mucins and mucin-type carbohydrates has been described in many types of cancer, including mucoepidermoid carcinoma (MEC), a malignant salivary gland tumor. In this study, we examined the aberrant expression patterns of mucins (MUC1, MUC4, MUC5AC and MUC5B), simple mucin-type carbohydrate antigens (Tn, sialyl-Tn and T) and mature carbohydrate antigens (Lewis(a) and sulfo-Lewis(a) antigens) in MEC originating from the parotid gland, which normally does not secrete mucins...

OBJECTIVE: The aim of the study was to estimate the radiation-absorbed doses and to study the in vivo and in vitro stability as well as pharmacokinetic characteristics of lutetium-177 (Lu-177) prostate-specific membrane antigen (PSMA)-617. METHODS: For this purpose, 7 patients who underwent Lu-177-PSMA therapy were included into the study. The injected Lu-177-PSMA-617 activity ranged from 3.6 to 7.4 GBq with a mean of 5.2±1.8 GBq. The stability of radiotracer in saline was calculated up to 48 h...
