RESUMEN
Metastatic renal cell carcinoma (mRCC) is tumor resistant to all cytotoxic agents. During the last decade, effective targeted therapies emerged including sunitinib, pazopanib and the combination of bevacizumab with IFN-α. The use of bevacizumab plus IFN-α combination in mRCC is supported by the AVOREN trial. Although the primary end point of the AVOREN trial was overall survival, progression-free survival was used to evaluate efficacy and served as the basis of regulatory submission owing to the advent of targeted agents that probably resulted in the prolongation of overall survival in both experimental and control arms. The doubling of median progression-free survival in the AVOREN trials (from 5.4 to 10.2 months) is remarkably similar compared with the results of Phase III trials with sunitinib and pazopanib. Bevacizumab plus IFN-α is the only combined regimen currently used in mRCC and serves as a comparator in the trials combining bevacizumab with other agents.

Metastases of esophageal carcinoma to the skeletal muscle are rare, but the incidence may be increasing because of better diagnosis resulting from widespread use of positron emission tomography/computed tomography (PET/CT). A cohort of 205 patients with esophageal carcinoma treated at our center who had PET/CT between 2006 and 2010 was retrospectively evaluated for the presence of skeletal muscle metastases. Four patients had skeletal muscle metastases of esophageal carcinoma, including two patients with squamous cell carcinoma. In another patient with squamous cell carcinoma of the esophagus and synchronous skeletal muscle metastases, muscle metastases were subsequently shown to be related to second primary pancreatic adenocarcinoma. In all cases, skeletal muscle metastases were the first manifestation of systemic disease. In three patients palliation was obtained with the combination of external beam radiation therapy, systemic chemotherapy or surgical resection. Skeletal muscle metastases are a rare complication of esophageal carcinoma.

AIM: To investigate the relation between intima-media thickness (IMT) and laboratory parameters of atherosclerosis risk in patients with breast carcinoma. PATIENTS AND METHODS: IMT and a panel of laboratory parameters associated with the risk of atherosclerosis were studied in 192 patients with histologically-verified breast carcinoma. RESULTS: Patients with metastatic disease had significantly higher fibrinogen, C-reactive protein (CRP), urinary neopterin and mean IMT, and significantly lower serum albumin and hemoglobin concentrations. Significant correlations were observed between CRP, urinary neopterin, mean IMT and other parameters of cardiovascular risk. Age was an independent predictor of the presence of sonographic signs of atherosclerosis using logistic regression, and age, glucose, time from start of chemotherapy, high-density lipoprotein cholesterol, D-dimers were independently associated with IMT in stepwise regression models. CONCLUSION: In addition to the associations between IMT and laboratory or clinical parameters of the risk of atherosclerosis, IMT may also be associated with the time from chemotherapy.
