Purpose
Targeted therapy has brought great clinical benefits for patients with multiple solid tumors, but its effects in patients with locally advanced/metastatic pancreatic cancer (LA/MPC) are disputed. This systematic evaluation compared the efficacy and safety profiles of gemcitabine combined with targeted agents (GEM + TA) versus gemcitabine administered as monotherapy or combined with placebo (GEM ± PLC) in LA/MPC patients.Methods
PubMed and EMBASE were searched for relevant randomized controlled trials published on or before April 30, 2013. The primary end points were overall survival (OS) and progression-free survival (PFS); the secondary end points were 1-year survival rate, objective response rate (ORR), and toxicity rates (TRs), defined as the prevalence of grade 3/4 adverse events. The systematic evaluation was performed by using Review Manager version 5.1.7.Findings
A total of 10 randomized controlled trials involving 3899 patients (2195 males; mean age, 63.6 years) were included in the systematic evaluation. The results reported that there was no significant difference in OS (hazard ratio [HR] = 0.97 [P = 0.85]), PFS (HR = 0.95 [P = 0.14]), or ORR (odds ratio [OR] = 0.95 [P = 0.69]) between GEM + TA and GEM ± PLC. However, a marginal difference in 1-year survival rate (OR = 0.80 [P = 0.05]) between the 2 groups was observed. The grade 3/4 TRs of anemia, diarrhea, nausea, neutropenia, thrombocytopenia, and vomiting were not significantly different between the 2 groups. However, the prevalence of grade 3/4 rash was significantly greater in the GEM + TA group (OR = 8.31 [P < 0.01]).Implications
Based on the results from this analysis, the addition of targeted agents to a regimen of gemcitabine treatment does not bring survival benefits except 1-year survival rate to patients with LA/MPC. 相似文献3.

We sought to investigate whether concurrent exposure to pulsed high-intensity focused ultrasound (HIFU) and the chemotherapeutic drug gemcitabine would enhance apoptosis in pancreatic cancer. A pancreatic cancer xenograft model was established using BALB/c nude mice and human pancreatic cancer cells (PANC-1). In the first study, mice were randomly allocated into one of four groups: control (n = 4), HIFU alone (n = 4), gemcitabine (GEM) alone (n = 28) and concurrent treatment with HIFU and gemcitabine (HIGEM) (n = 28). The GEM and HIGEM groups were subdivided into four subgroups (16 mice) according to the drug dose injected (50–200 mg/kg) and another four subgroups (16 mice) according to the time interval between drug injection and HIFU treatment (each subgroup, n = 4). Apoptosis rates were evaluated using the TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling) assay and percentage of necrosis, as evaluated with Harris' hematoxylin solution and eosin Y stain, 3 d after treatment. The second study was performed to evaluate tumor growth rates of the four groups. Each group was treated weekly for 3 wk, and tumor size was periodically measured for up to 4 wk from the beginning of treatment. In the first study, overall rates of apoptosis were significantly higher in the HIGEM group than in the GEM group (p = 0.02). In a subgroup analysis, HIGEM was superior to GEM in enhancing apoptosis at gemcitabine dosages of 150–200 mg/kg gemcitabine and intervals between gemcitabine and HIFU less than 2 h (p = 0.01). In the second study, HIGEM treatment resulted in the slowest tumor growth. However, despite a visible distinction, none of the differences found between the HIGEM and GEM groups were statistically significant (p > 0.05). Treatment with both HIFU and gemcitabine might enhance cell apoptosis and reduce tumor growth in pancreatic carcinoma. For this concurrent treatment, a high dosage of gemcitabine and a short-term delay before HIFU are recommended to maximize the therapeutic effect. 相似文献
