BACKGROUND: Comorbidity has a great impact on lung cancer survival. Renal function status may affect treatment decisions and drug toxicity. The survival outcome in lung cancer patients with coexisting chronic kidney disease (CKD) has not been fully evaluated. We hypothesized that CKD is an independent risk factor for mortality in patients with lung cancer. METHODS: A retrospective, propensity-matched study of 434 patients diagnosed between June 2004 and May 2012 was conducted...

Curcumin has high potential in suppressing many types of cancer and overcoming multi-drug resistance in a multi-faceted manner by targeting diverse molecular targets. However, the rather low systemic bioavailability resulted from its extremely low aqueous solubility and rapid metabolism and excretion in vivo has hampered its application in cancer therapy. With the primary aim to increase the aqueous solubility of curcumin while retaining its stability in the blood circulation before it accesses the tumor site, here we report preparation of curcumin-loaded N-(tert-butoxycarbonyl)-L-phenylalanine end-capped methoxy-poly(ethylene glycol)-block-poly(ε-caprolactone) (mPEG-PCL-Phe(Boc)) micelles with high stability both in vitro and in vivo and anti-tumor efficacy...

BACKGROUND: Prostate-specific membrane antigen (PSMA) is highly over-expressed in advanced prostate cancers. (68)Ga-labeled PSMA inhibitors (iPSMA) are currently used for prostate cancer detection by PET imaging. The availability of simple, efficient and reproducible radiolabeling procedures is essential for developing new SPECT radiopharmaceuticals for clinical translation. The aim of this research was to prepare (99m)Tc-EDDA/HYNIC-Lys(Nal)-Urea-Glu ((99m)Tc-EDDA/HYNIC-iPSMA) obtained from lyophilized kit formulations and evaluate the in vitro and in vivo radiopharmaceutical binding to prostate cancer cells over-expressing PSMA, as well as the (99m)Tc-EDDA/HYNIC-iPSMA normal biodistribution in humans and the preliminary uptake in patients with prostate cancer...

Metal-based drugs have shown early promise as anticancer agents suggesting the potential application of silver(I) complexes as apoptosis-inducing agents. The ability of a silver(I) cyanide containing phosphine complex to induce cell death was evaluated in both a malignant (SNO esophageal cancer) and non-malignant (HDF-a skin and HEK293 kidney) cell lines. A dose-dependent decrease in cell viability was observed in the SNO cells. Light microscopy revealed morphological features indicative of apoptotic cell death...

Cardenolides are cardiac glycosides, mostly obtained from natural sources. They are well known for their inhibitory action on the Na,K-ATPase, an effect that regulates cardiovascular alterations such as congestive heart failure and atrial arrhythmias. In recent years, they have also sparked new interest in their anticancer potential. In the present study, the cytotoxic effects of the natural cardenolide convallatoxin (CON) were evaluated on non-small cell lung cancer (A549 cells). It was found that CON induced cytostatic and cytotoxic effects in A549 cells, showing essentially apoptotic cell death, as detected by annexin V-propidium iodide double-staining, as well as changes in cell form...

BACKGROUND: While (68)Ga-PSMA PET-MRI might be superior to PET-CT with regard to soft tissue assessment in prostate cancer evaluation, it is also known to potentially introduce additional PET image artefacts. Therefore, the impact of PET acquisition duration and attenuation data on artefact occurrence, lesion detectability, and quantification was investigated. To this end, whole-body PET list mode data from 12 patients with prostate cancer were acquired 1 h after injection of 2 MBq/kg [(68)Ga]HBED-CC-PSMA on a hybrid PET-MRI system...

BACKGROUND: Angiomyolipoma (AML), typically composed of smooth muscle, vessels, and fat, is generally a benign tumor in the kidneys. However, it occasionally occurs in extrarenal sites and behaves like a malignant tumor. AML is uncommonly encountered in fine-needle aspiration (FNA) samples and can cause diagnostic difficulty. METHODS: We searched our pathology database for FNA cases diagnosed between 2003 and 2015 that were subsequently confirmed to be AML in the same lesion by surgical pathologic evaluation...

High overexpression of sigma (σ) receptors (σ1 and σ2 subtypes) in a variety of human solid tumors has prompted the development of σ receptor-targeting radioligands, as imaging agents for tumor detection. A majority of these radioligands to date, target the σ2 receptor, a potential marker of tumor proliferative status. The identification of approximately equal proportions of both σ receptor subtypes in prostate tumors, suggests that a high affinity, dual σ receptor-targeting radioligand could potentially provide enhanced tumor targeting efficacy in prostate cancer...
