Lonidamine, an anticancer drug that acts on mitochondria, has poor water solubility. Mitochondria are the primary source of cellular reactive oxygen species (ROS), which are necessary for photodynamic therapy. Hence, a mitochondria-targeting drug delivery system loaded with Lonidamine and a ROS-produced photosensitizer could improve the bioavailability of Lonidamine and maximize photodynamic therapeutic efficiency. Here we report, for the first time, new IR-780 and Lonidamine encapsulated mitochondria-targeting thermosensitive liposomes (IL-TTSL)...

Primary lung sarcoma (PLS) is an extremely rare, very aggressive malignancy. Surgical removal is considered the treatment of choice, and patients who have been given conventional radiotherapy have had inferior outcomes. This study is the first describing a case of PLS treated with stereotactic ablative radiotherapy (SABR), which precisely targets a small tumor with a markedly higher biologically effective dose than conventional radiotherapy. The patient was an 82-year-old man who was diagnosed with primary lung leiomyosarcoma based on radiology, pathology, and immunohistochemical examinations...

AIMS: The National Institute for Healthcare Excellence recommends continuous hyperfractionated, accelerated radiotherapy (CHART), concurrent chemoradiation (cCRT) and stereotactic ablative radiotherapy (SABR) for appropriate patients with non-small cell lung cancer (NSCLC), but these are not universally available in all UK radiotherapy centres. Reduced access to these treatments may be contributing to reduced survival, with the concern that elderly patients are less likely to receive guideline-recommended therapy (GRT)...

The lysyl oxidase-like protein LOXL2 has been suggested to contribute to tumor progression and metastasis, but in vivo evidence has been lacking. Here we provide functional evidence that LOXL2 is a key driver of breast cancer metastasis in two conditional transgenic mouse models of PyMT-induced breast cancer. LOXL2 ablation in mammary tumor cells dramatically decreased lung metastasis, whereas LOXL2 overexpression promoted metastatic tumor growth. LOXL2 depletion or overexpression in tumor cells does not affect extracellular matrix stiffness or organization in primary and metastatic tumors, implying a function for LOXL2 independent of its conventional role in extracellular matrix remodeling...

PURPOSE: Although stereotactic ablative body radiotherapy (SABR) is widely used therapeutic technique, predictive factors of radiation pneumonitis (RP) after SABR remain undefined. We aimed to investigate the predictive factors affecting RP in patients with primary or metastatic lung tumors who received SABR. MATERIALS AND METHODS: From 2012 to 2015, we reviewed 59 patients with 72 primary or metastatic lung tumors treated with SABR, and performed analyses of clinical and dosimetric variables related to symptomatic RP...

BACKGROUND: Treatment of adrenal metastasis from lung carcinoma may prolong survival in the selected patients. However, not all patients can undergo surgery; thus, minimally invasive ablation procedures such as radiofrequency ablation (RFA) and microwave ablation (MWA) have gained acceptance as alternative treatment methods. This study summarized a 5-year single-center experience regarding the evaluation of safety and efficacy of computed tomography (CT)-guided thermal ablation in the management of adrenal metastasis originating from non-small cell lung cancer (NSCLC)...

Methadone maintenance treatment (MMT) is the major tapering therapy for morphine addictive patients. There have gender differences reported in response to MMT. This study discovered that the estrogen-response element single nucleotide polymorphism (ERE-SNP; rs16974799, C/T) of cytochrome 2B6 gene (cyp2b6; methadone catabolic enzyme) responded differently to MMT dosing. Oestradiol was associated with high MMT dosing, high enantiomer (R- or S-) of 2-ethylidene-1,5-dimethyl-3,3-dipheny-pyrrolidine (EDDP; methadone metabolite) to methadone ratio and increased drug-seeking behaviour, implicating oestradiol-CYP-EDDP/methadone axis decreasing MMT efficacy...

Attaching affinity ligands to nanoparticles (NPs) increases selectivity for targeting cells and tissues, and can result in improved sensitivity and reduced off-target toxicity in diagnostic and therapeutic systems. The decision over key features - NP size, shape, coating strategies and targeting ligands for clinical translation is often hampered by a lack of quantitative in vivo NP homing assays. Sensitive, internally controlled assays are needed which allow for quantitative comparisons (auditions) among various formulations of targeted NPs...

We have recently developed a flexible catheter electrode used for bronchoscopic radiofrequency ablation (RFA). Two patients with nonsurgical stage IA peripheral lung cancer and 1 with lung metastasis underwent treatment with flexible catheter RFA utilizing navigation bronchoscopy. Chest computed tomography (CT) and positron emission tomography/CT (PET/CT) were performed before and after RFA to assess the ablation response of the patients. One patient's tumor had no prior PET uptake and therefore no follow-up PET was obtained...

In recent years, there have been many reports about the efficacy of stenting for central bronchial stenosis. When central bronchial stenosis is due to metastasis of a malignant tumor to the trachea and/or bronchi (endobronchial metastasis: EM), it is classified as "narrow EM" and "broad EM." [1] We managed two patients in whom bilateral stent placement was required for narrow and broad EM arising from colorectal cancer. Case 1: In September 2011, a 66-year-old man underwent low anterior resection for advanced colorectal cancer associated with unresectable liver metastasis...

PURPOSE: Stereotactic ablative radiation therapy (SABR) is an established treatment for selected lung tumors. Sinoatrial node (SAN) toxicity after thoracic SABR has not been reported in the literature. We sought to understand the risk of SAN toxicity owing to incidental dose to the SAN from SABR. METHODS AND MATERIALS: We conducted a retrospective review of patients with early-stage lung cancer or limited pulmonary metastases who underwent thoracic SABR to a right-sided central lung tumor (within 2 cm of the mainstem bronchus or other mediastinal structures) between January 2008 and December 2014, analyzed a subset whose treatment imparted dose to the SAN exceeding 10% of the prescription dose, and examined patient and treatment dosimetric characteristics...

Intrauterine or fetal growth restriction (IUGR) is a major complication of pregnancy and leads to significant perinatal morbidities and mortality. Typically, induction of IUGR in animals involves the complete occlusion or ablation of vessels to the uterus or placenta, acutely impairing blood flow and fetal growth, usually with high fetal loss. We aimed to produce a model of reduced fetal growth in the spiny mouse with minimal fetal loss. At 27 days gestational age (term is 38-39 days), a piece of silastic tubing was placed around the left uterine artery to prevent the further increase of uterine blood flow with advancing gestation to induce IUGR (occluded)...

PURPOSE: Assess the dosimetric impact of multi-leaf collimator (MLC) tracking and mid-ventilation (midV) planning compared with the internal target volume (ITV)-based planning approach for lung Stereotactic Ablative Body Radiotherapy (SABR). METHOD: Ten lung SABR patients originally treated with an ITV-based plan were re-planned according to MLC tracking and midV planning schemes. All plans were delivered on a linac to a motion phantom in a simulated treatment with real lung motions...

BACKGROUND: Stereotactic body radiotherapy (SBRT) or stereotactic ablative radiotherapy (SABR) has been reported to be a comparable alternative therapy to surgery for patients with T1-3N0M0 non-small cell lung cancer (NSCLC). However, it has not been clarified whether SBRT/SABR is as effective as surgery. We conducted this study to compare the efficacy of SBRT/SABR and surgery in the treatment of T1-3N0M0 NSCLC. MATERIALS AND METHODS: An electronic and a manual search of the literature was conducted in PubMed, Embase, and the Wiley Online Library in all published data before January 1, 2017...

A 46-year-old woman with a history of papillary thyroid cancer status post total thyroidectomy underwent the second I radioiodine ablation therapy for lung metastases. Posttherapeutic whole-body I planar images showed diffuse uptake in the lungs and intense focal activity in both sides of the upper abdomen. SPECT/CT of the abdomen localized the uptake in the upper pole of the left kidney and the lower pole of the right kidney. The patient received bilateral partial nephrectomy with pathology demonstrating that these 2 renal lesions were renal hamartomas...
