BACKGROUND Nasopharyngeal carcinoma (NPC) is an endemic neoplasm in southern China. Although NPC sufferers are sensitive to radiotherapy, 20-30% of patients finally progress with recurrence and metastases. Elevated lymphocyte-to-monocyte ratio (LMR) has been reported to be associated with favorable prognosis in some hematology malignancies, but has not been(More)
BACKGROUND Concurrent chemoradiotherapy (CCRT) has been shown to improve outcomes for stage III-IV nasopharyngeal carcinoma (NPC) patients compared with radiotherapy (RT) alone, but the effectiveness of the combined therapy for stage II NPC patients is unknown. METHODS Patients with Chinese 1992 stage II NPC were randomly assigned to receive either RT(More)
PURPOSE To evaluate which patients with nasopharyngeal carcinoma (NPC) obtained the greatest benefits from the detection of distant metastasis with [(18)F]fluorodeoxyglucose positron emission tomography and computed tomography (PET/CT) combined with plasma Epstein-Barr virus (EBV) DNA levels. PATIENTS AND METHODS Consecutive patients with NPC were(More)
BACKGROUND This study aimed to establish an effective prognostic nomogram with or without plasma Epstein-Barr virus DNA (EBV DNA) for nondisseminated nasopharyngeal carcinoma (NPC). METHODS The nomogram was based on a retrospective study of 4630 patients who underwent radiotherapy with or without chemotherapy at Sun Yat-sen University Cancer Center from(More)
This paper presents an odometer architecture which combines a monocular camera and an inertial measurement unit (IMU). The trifocal tensor geometry relationship between three images is used as camera measurement information, which makes the proposed method without estimating the 3D position of feature point. In other words, the proposed method does not have(More)
BACKGROUND To evaluate the survival benefit of intensity-modulated radiotherapy (IMRT) compared with conventional two-dimensional radiotherapy (2D-CRT) in nasopharyngeal carcinoma (NPC) using a large cohort with long follow-up. METHODS We retrospectively analysed 7081 non-metastatic NPC patients who received curative IMRT or 2D-CRT from February 2002 to(More)
PURPOSE This study was focused on the serial changes in magnetic resonance images (MRI) of the skull-base bone that occur after endoscopic nasopharyngectomy in patients with local recurrent nasopharyngeal carcinoma (rNPC). MATERIALS AND METHODS Nine patients with histologically proven rNPC were enrolled in this study. Two experienced radiologists(More)
BACKGROUND Salvage ENPG and IMRT are more effective treatments for rNPC than traditional 2-dimensional radiotherapy. However, compared with IMRT, the benefits of ENPG have not yet been clearly described. METHODS We defined a resectable area in which the disease could be radically removed using ENPG and our imaging specialists selected eligible patients(More)
BACKGROUND Intracavitary brachytherapy (ICBT) is usually applied as boost radiotherapy for superficial residual of nasopharyngeal carcinoma (NPC) after primary extern-beam radiptherapy (ERT). Here, we evaluated the outcome of endoscope-guided interstitial intensity-modulated brachytherapy (IMBT) boost radiation for deep-seated residual NPC. (More)
The impact of cumulative dose of cisplatin on clinical outcomes of nasopharyngeal carcinoma (NPC) patients who received intensity-modulated radiotherapy (IMRT) was evaluated. This study included 491 consecutive patients with histologically confirmed NPC who were treated with concurrent chemoradiotherapy with IMRT. The patients were divided into three(More)
