Association of lung and heart dose with survival in patients with non-small cell lung cancer underwent volumetric modulated arc therapy.

Background: Controversial conclusions had been reported in studies trying to confirm the impact of heart dose on overall survival (OS) reported in RTOG 0167 for non-small cell lung cancer (NSCLC) patients who underwent radiotherapy (RT). The purpose of this study is to investigate the association of lung and heart dosimetric parameters with OS in NSCLC patients treated by volumetric modulated arc therapy (VMAT).

Methods: Inoperable NSCLC patients treated by VMAT from March 2012 to December 2015 were retrospectively reviewed.

Safety and outcomes of volumetric modulated arc therapy in the treatment of patients with inoperable lung cancer.

: Published data on the effects and toxicities of volumetric modulated arc therapy (VMAT) in the management of inoperable lung cancer are scarce. : The clinical outcomes and pulmonary toxicities of 134 patients with consecutive inoperable lung cancer who underwent VMAT from March 2011 to September 2016 were retrospectively reviewed. The dosimetric and characteristic factors associated with acute radiation pneumonitis (RP) and pulmonary fibrosis were evaluated with univariate and multivariate analysis.

The effect of the primary tumor location on the survival of colorectal cancer patients after radical surgery.

Colorectal cancer is one of the most common cancers and the leading cause of cancer-related death worldwide. The impact of the primary tumor location on the prognosis of patients with colorectal cancer has long been a concern, but studies have led to conflicting conclusions. In total, 465 colorectal cancer patients who received radical surgery were reviewed in this study.

Induction chemotherapy plus concurrent chemoradiotherapy versus induction chemotherapy plus volumetric modulated arc therapy alone in the treatment of stage II-IVB nasopharyngeal carcinoma patients: a retrospective controlled study.

Background: In the era of intensity-modulated radiotherapy (IMRT), the role of additional concurrent chemotherapy (CC) to radiotherapy (RT) after induction chemotherapy (IC) compared to IC followed by RT alone remains unclear for stage II-IVB nasopharyngeal carcinoma (NPC) patients. The aim of this study was to evaluate the efficacy and toxicities of IC/RT and IC/CCRT in the treatment of NPC with volumetric modulated arc therapy (VMAT).

Methods: From January 2012 to March 2016, a total of 217 NPC patients were retrospectively assessed.

A type II first branchial cleft cyst masquerading as an infected parotid Warthin's tumor.

The diagnosis of a parotid mass usually depends on thorough history taking and physical examination. Diagnostic modalities, including ultrasonographic examinations, computed tomography and magnetic resonance images, may also provide substantial information but their accuracy for diagnosis is sometimes questionable, especially in differentiating some rare neoplasms. First branchial cleft cysts (FBCCs) are rare causes of parotid swelling and comprise less than 1% of all branchial anomalies.
