Background: EBT and EBT3 radioChromic films have been used in radiotherapy dosimetry for years.Objective: The aim of the current study is to compare EBT and EBT3 radioChromic films in dosimetry of radiotherapy fields for treatment of parotid cancer.Methods: Calibrations of EBT and EBT3 films were performed with identical setups using a 6 MV photon beam of a Siemens Primus linac. Skin dose was m...

Parotid gland and cerebellum metastasis in lung cancer are extremely rare; very few cases have been reported. Here we present a case of a 56-year-old Chinese female patient who presented with a swelling in the right parotid gland. We diagnosed metastatic squamous-cell carcinoma from advanced lung cancer. The patient received 1 cycle nimustine (100 mg/m2 IV Day 1) and nedaplatin (80 mg/m2 IV Day...

Xerostomia (dry mouth), resulting from radiation damage to the parotid glands, is one of the most common and distressing side effects of head-and-neck cancer radiotherapy. Recent MRI studies have demonstrated that the volume reduction of parotid glands is an important indicator for radiation damage and xerostomia. In the clinic, parotid-volume evaluation is exclusively based on physicians' manu...

BACKGROUND Parotid gland metastasis in lung cancer is extremely rare, very few cases have been reported. CASE PRESENTATION We report on the case of a 61-year-old Chinese male patient who presented with parotid swelling metastasizing from advanced lung cancer. We therefore performed an operation of partial parotidectomy with preservation of the facial nerve and advised the patient receive chem...

OBJECTIVES/HYPOTHESIS Additional intraoperative guidance could reduce the risk of iatrogenic injury during parotid gland cancer surgery. We evaluated the intraoperative use of fluorescently labeled nerve binding peptide NP41 to aid facial nerve identification and preservation during parotidectomy in an orthotopic model of murine parotid gland cancer. We also quantified the accuracy of intraoper...

BACKGROUND: Parotid gland metastasis in breast cancer is extremely rare, and only 14 cases have been reported between 1982 and 2010. CASE REPORT: A 67-year-old female patient was diagnosed with invasive lobular carcinoma of the left breast. Although clinical staging was T1N3M1 (stage IV), the tumor experienced a complete response to chemotherapy. We therefore performed a mastectomy followed by...

BACKGROUND Robot-assisted neck dissection in patients with head and neck cancer has been demonstrated to be feasible. We conceived a surgical technique of surgery for parotid cancer with the robotic system via a gasless modified facelift (MFL) approach. A detailed surgical technique is provided. METHODS In a 28-year-old female patient with parotid cancer, the disease was treated with primary ...

Purpose: Parotid cancer is a rare malignancy characterized by a heterogeneous histologic subtype and distinct biologic behavior. The present study aimed to externally validate and compare the performances of the American Joint Committee on Cancer (AJCC) staging system (7th Edition), Carrillo score, and Vander Poorten score in the prediction of tumor relapse probability in a large cohort of Asia...

SUMMARY: BACKGROUND: Metastases to the parotid and thyroid glands from breast cancer are rare and have a poor prognosis. CASE REPORT: We present the case of a patient with breast carcinoma and synchronous involvement of both the parotid and thyroid gland, and review the literature on this subject. CONCLUSION: Metastatic malignancy in clinically suspect thyroid and parotid nodules could be detec...

Manual assessment of parotid gland status from magnetic resonance imaging is a subjective, time consuming and error prone process. Automatic image analysis methods offer the possibility to get consistent, objective rapid diagnoses tumor. In this kind cancer, large variety in their characteristics, that brings various difficulties for traditional methods. paper, we propose an automatic method pe...
