Circulating Tumor Cells in Right- and Left-Sided Colorectal Cancer.

Molecular alterations are not randomly distributed in colorectal cancer (CRC), but rather clustered on the basis of primary tumor location underlying the importance of colorectal cancer sidedness. We aimed to investigate whether circulating tumor cells (CTC) characterization might help clarify how different the patterns of dissemination might be relative to the behavior of left- (LCC) compared to right-sided (RCC) cancers. We retrospectively analyzed patients with metastatic CRC who had undergone standard baseline CTC evaluation before starting any first-line systemic treatment.

Palbociclib plus endocrine therapy in HER2 negative, hormonal receptor-positive, advanced breast cancer: A real-world experience.

Data from 423 human epidermal growth factor receptor 2-negative (HER2-), hormone receptor-positive (HR+) advanced breast cancer (aBC) patients treated with palbociclib and endocrine therapy (ET) were provided by 35 Italian cancer centers and analyzed for treatment outcomes. Overall, 158 patients were treated in first line and 265 in second/later lines. We observed 19 complete responses and 112 partial responses.

N-Palmitoyl Ethanol Amide Pharmacological Treatment in Patients With Nonsurgical Lumbar Radiculopathy.

Palmitoyl ethanol amide (PEA) is an endogenous substance that plays a role in neuropathic pain. In this article, we evaluated both the safety and the efficacy of ultramicronized PEA (um-PEA) in the treatment of low back pain related to nonsurgical lumbar radiculopathy. In this prospective single-blind study, patients with low back pain related to nonsurgical lumbar radiculopathy received the fixed combination acetaminophen/codeine (500 mg + 30 mg/d) for 7 days, and then it was stopped and changed to um-PEA (1200 mg/d) for 30 days.

Drug-Drug Interactions in Cocaine-users and their Clinical Implications.

Background: Drug-Drug Interactions (DDIs) represent a common problem in clinical practice during drug treatments. DDIs can both induce the development of adverse drug reactions or reduce the clinical efficacy of each drug.

Objectives: The main objective of this review was to analyze the pharmacokinetic and pharmacodynamic DDIs in cocaine consumers, focusing the interest on their clinical implications.

Vascular Endothelial Growth Factor Inhibitor Therapy and Cardiovascular and Renal Damage in Renal Cell Carcinoma.

Background: Sunitinib, a tyrosine kinase inhibitor of vascular endothelial growth factor (VEGF), is approved for first and second line treatment of advanced renal cell carcinoma (RCC). Knowledge on the effects of sunitinib on cardiovascular (CV) risk and renal damage is limited.

Aim: To evaluate possible renal and CV damage in patients with RCC treated with sunitinib.
