EGFR and K-Ras mutations in women with lung adenocarcinoma: implications for treatment strategy definition.

Background: We aimed at investigating the outcomes of female patients with stage IIIB-IV adenocarcinoma of the lung according to EGFR and K-Ras mutational status.

Methods: One hundred and three consecutive female patients genotyped at a single Italian Institution were analyzed. Patients were planned to receive first-line platinum-based chemotherapy (CT) and a salvage treatment with anti-EGFR tyrosine-kinase inhibitors (TKIs) was proposed irrespective of tumor mutational status.

Bevacizumab in the pre-operative treatment of locally advanced rectal cancer: a systematic review.

Despite advances in the management of patients with locally advanced, non-metastatic rectal adenocarcinoma (LARC), prognosis remains largely unsatisfactory due to a high rate of distant relapse. In fact, currently available neoadjuvant protocols, represented by fluoropyrimidine-based chemo-radiotherapy (CT-RT) or short-course RT, together with improved surgical techniques, have largely reduced the risk of local relapse, with limited impact on distant recurrence. Available results of phase III trials with additional cytotoxic agents combined with standard CT-RT are disappointing, as no significant reduction in the risk of recurrence has been demonstrated.

Dissecting signaling pathways in hepatocellular carcinoma: new perspectives in medical therapy.

Prognosis of patients with advanced hepatocellular carcinoma (HCC) is poor and is largely influenced by associated liver comorbidities. Moreover, effective treatment alternatives are limited; with the exception of the multitargeted inhibitor sorafenib, established options in the treatment of advanced HCC no longer amenable with ablative or locoregional procedures are lacking. In light of the limited efficacy of chemotherapy in this setting, great efforts have been made in the definition of targetable molecular pathways with a central role in the progression of HCC.

From clinical trials to clinical practice: predictors of response to erlotinib in advanced non-small cell lung cancer patients pretreated with chemotherapy.

Background: Inhibition of the epidermal growth factor receptor pathway with tyrosine kinase inhibitors can improve outcome of patients with advanced non-small cell lung cancer after first-line chemotherapy. The use of clinical characteristics and molecular markers may permit the identification of patients who are more likely to benefit from erlotinib.

Patients And Methods: Retrospective analysis of unselected patients with metastatic non-small cell lung cancer who had previously failed on at least one line of chemotherapy and treated at our institution with erlotinib (150 mg/day orally) until disease progression.

Targeted delivery of albumin bound paclitaxel in the treatment of advanced breast cancer.

Taxanes are chemotherapeutic agents with a large spectrum of antitumor activity when used as monotherapy or in combination regimens. Paclitaxel and docetaxel have poor solubility and require a complex solvent system for their commercial formulation, Cremophor EL(R) (CrEL) and Tween 80(R) respectively. Both these biological surfactants have recently been implicated as contributing not only to the hypersensitivity reactions, but also to the degree of peripheral neurotoxicity and myelosuppression, and may antagonize the cytotoxicity.
