RESUMO

Cancers of the liver are one of the commonest cancers that occur in the world, the commonest of which is the hepatocellular carcinoma (HCC). It is considered to be the 5th commonest cancer in the world. In the areas that are endemic for hepatitis B and C, it is extremely common. Unfortunately, India which is an endemic zone for hepatitis B, there has been no comprehensive analyzed data for HCC. Incidence of HCC in India occurs at two peaks, one at a young age between 40 to 55 years and another above 60 years. Eighty per cent of all HCCs occurring in India occur with cirrhosis of liver in the background and 60% of all these cases are hepatitis B positive carriers. Symptoms are reflective of late presentation with advanced disease. Surgery, the only curative modulus available, unfortunately is not possible in 95% of HCC patients. Majority of the patients are treated with palliative and supportive care and life spans are limited. Sorafenib is used in a small section of patients. Characterization of HCC with molecular sub-typing is the need of the hour.

RESUMO

AIMS: Paclitaxel is extensively used in the treatment of advanced carcinomas of the breast, ovary and non-small cell lung cancer. In clinical use it is formulated in the non-ionic surfactant polyethoxylated castor oil (Cremophor) and dehydrated alcohol to enhance drug solubility. Cremophor adds to toxic effects of paclitaxel by producing or contributing to the well-described hypersensitivity reactions that commonly occur during its infusion, affecting a large number of patients. This randomized trial was conducted to evaluate efficacy and safety of novel nanoparticle-based paclitaxel in the treatment of patients with advanced breast cancer. METHOD: Patients were randomized to receive either nanoparticle paclitaxel (NP) 300 mg/m(2) , (NP300) or NP220 mg/m(2) or Cremophor paclitaxel 175 mg/m(2) (CP 175). NP was administered as a 1-h infusion without premedication and CP as a 3-h infusion with premedication every 3 weeks. RESULTS: In total, 194 patients who had been administered at least one dose were included for safety analysis and 170 patients who completed at least two cycles of therapy were analyzed for efficacy. NP showed an overall response rate (complete response + partial response) of 40% in the NP220 and NP300 arms as compared to 31% in the CP arm. The incidence of neutropenia (all grades) was lowest in the NP220 arm (39.4%) compared to the NP300 (55%) and CP arm (50%). CONCLUSION: NP is well tolerated and can be safely administered without any premedication in comparison to conventional paclitaxel, which requires the use of premedication before administration. NP demonstrates promising efficacy with a favorable safety profile.

RESUMO

PURPOSE: Vandetanib is a once-daily, oral inhibitor of vascular endothelial growth factor receptor and epidermal growth factor receptor signaling. The antitumor activity of vandetanib monotherapy or vandetanib with paclitaxel and carboplatin (VPC) was compared with paclitaxel and carboplatin (PC) in previously untreated patients with non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: All NSCLC histologies and previously treated CNS metastases were permitted in this partially blinded, placebo-controlled, randomized phase II study. Patients were randomly assigned 2:1:1 to receive vandetanib, VPC, or PC. Progression-free survival (PFS) was the primary end point, and the study was powered to detect a reduced risk of progression with VPC versus PC (hazard ratio = 0.70; one-sided P < .2) and to demonstrate noninferiority for vandetanib versus PC. Overall survival was a secondary assessment. RESULTS: The risk of progression was reduced for patients receiving VPC (n = 56) versus PC (n = 52; hazard ratio = 0.76, one-sided P = .098); median PFS was 24 weeks (VPC) and 23 weeks (PC). The vandetanib monotherapy arm (n = 73) was discontinued after a planned interim PFS analysis met the criterion for discontinuation (hazard ratio > 1.33 v PC). Overall survival was not significantly different between patients receiving VPC or PC. Rash, diarrhea, and hypertension were common adverse events; no pulmonary or CNS hemorrhage events required intervention. CONCLUSION: VPC could be safely administered to patients with NSCLC, including those with squamous cell histology and treated brain metastases. Compared with the PC control arm, patients receiving VPC had longer PFS, meeting the prespecified study end point, whereas those receiving vandetanib monotherapy had shorter PFS.
