Model-based meta-analysis of dose response is a sophisticated method to guide dose and regimen selection. In this report, the effects of paclitaxel dose and regimen (weekly or every 3 weeks) on the efficacy and safety in cancer patients were quantified by model-based meta-analysis of 29 monotherapy trials. Logistic regression models were developed to assess the relationship between dose and obj...

The impact of maintenance therapy on progression-free survival and overall survival as well as quality of life of Chinese patients with metastatic colorectal cancer has long been under discussion. Recently, some phase III clinical trials have revealed that maintenance therapy can significantly prolong the progression-free survival while maintain an acceptable safety profile. Based on this evide...

PURPOSE To examine and compare patient and oncologist preferences for advanced melanoma treatment attributes and to document their trade-offs for benefits with risks. MATERIALS AND METHODS A discrete choice experiment (DCE) was conducted among advanced melanoma patients and oncologists. Qualitative pilot testing was used to inform the DCE design. A series of scenarios asked stakeholders to ch...

BACKGROUND Although interim analysis approaches in clinical trials are widely known, information on current practice of planned monitoring is still scarce. Reports of studies rarely include details on the strategies for both data monitoring and interim analysis. The aim of this project is to investigate the forms of monitoring used in cancer clinical trials and in particular to gather informati...

BACKGROUND The role of surgery for lung metastases (LM) secondary to colorectal cancer (CRC) remains controversial. The bulk of evidence is derived from single surgical series, hampering any definitive conclusions. The aim of this study was to compare the outcomes of CRC patients with LM submitted to surgery with those who were not. PATIENTS AND METHODS Data from 409 patients with LM as the f...

Historically, phase II trials in oncology generally had a single-arm design, constructed to distinguish between a tumor response rate felt to indicate a lack of promise (often 5%) and a rate that would indicate potential benefit (often 20%), with a one-sided type I error rate of 5% to 10% and a type II error rate of 10% to 20%. The dominant use of this design was based on the premise that an ag...

Abstract Background and objectives: Leukemia is one of the most prevalent cancers worldwide. The relapse of the disease mitigates patient survival time. The convenience of explaining the results obtained from analyzing tree models have encouraged doctors and paramedics to employ them in their research. The current study is an attempt to determine the five-year survival time and factors influen...
