The prophylactic conversion to an extended infusion schedule and use of premedication to prevent hypersensitivity reactions in ovarian cancer patients during carboplatin retreatment.
Repeated exposure to carboplatin can lead to hypersensitivity reactions during retreatment with carboplatin. This may prevent its further use in platinum-sensitive ovarian cancer patients. At our institution, an increasing proportion of patients are prophylactically converted to an extended schedule of infusion after 8 cycles of carboplatin. We sought to determine whether an incrementally increasing, extended 3-hour infusion of carboplatin with appropriate premedication was associated with a lower rate of hypersensitivity reactions compared to the standard 30-minute schedule in sequentially treated patients. ⋯ Our data suggest appropriate premedication and prophylactic conversion to an extended infusion during carboplatin retreatment may reduce hypersensitivity reactions.

ReviewNIH and NCI support for development of novel therapeutics in gynecologic cancer: a user's guide.
The development of novel therapeutics is a lengthy and often tortuous process. It frequently spans the identification of new targets, preclinical validation, discovery and refinement of novel therapies, safety studies, phase O, 1, 2, and 3 trials, and reverse translation. NIH and NCI provide via web sites a variety of resources and research tools of great value to investigators. ⋯ The NCI's effective partnership with industry and academia, as well as the ongoing NCI-supported clinical trials network, facilitates clinical development of novel therapeutics. Specialized NCI programs focused on cancer imaging, radiation research, and complementary and alternative medicine, also assist the development of novel agents. Finally, the NIH and the NCI sponsor a variety of grant mechanisms, supporting institutions, consortia, and individuals, which investigators seeking to develop novel therapeutics should make themselves familiar.

The vast number of novel targeted therapies available for testing in the United States dictates that a more efficient system aimed at identifying promising agents for phase III testing needs to be developed. Alternatives to traditional phase II trial design including alternative end points, randomized designs, biomarkers, and imaging tools are discussed. ⋯ Alternatives to traditional phase II trial design including alternative end points, randomized designs, biomarkers, and imaging tools should allow ineffective agents to be discarded and promising agents to undergo further investigation.

Adenocarcinoma of the cervix constitutes only approximately 20% of all cervical carcinomas; therefore, specific Level 1 evidence to guide patient management is lacking. Most trials have included this histologic subtype but in insufficient numbers to do more than generate hypotheses from subset analyses. ⋯ The purpose of this review was to give an overview of the current knowledge on adenocarcinoma of the cervix and its differences from squamous cell carcinoma with regard to risk factors, prognosis, survival rates, patterns of recurrence, and response to treatment. This article will focus on possible specific therapeutic directions to explore in the management of locally advanced adenocarcinomas.

Long-term persistence of anti-HPV-16 and -18 antibodies induced by vaccination with the AS04-adjuvanted cervical cancer vaccine: modeling of sustained antibody responses.
Strong and sustained HPV-16 and -18 antibody responses have been observed in previously unexposed women aged 15-25 years vaccinated with the AS04-adjuvanted HPV-16/18 L1 virus-like particle vaccine. While awaiting the extended results of ongoing trials, our objective was to predict the long-term persistence of anti-HPV-16/18 antibodies in vaccinees by applying three statistical models using immunogenicity data from vaccinated women with serum samples collected up to 6.4 years after first vaccination. Two different data lock-points (up to 5.5 years and up to 6.4 years) were used to assess the robustness of the models. ⋯ Vaccination with the AS04-adjuvanted HPV-16/18 vaccine is predicted to provide long-term persistence for both HPV-16 and -18 antibodies, independent of the statistical model applied. Model predictions are based on conservative mathematical assumptions. Since the input of longer term data of up to 6.4 years showed an improved profile compared with that for data up to 5.5 years, the predictions of antibody persistence based on population means are conservative when predicting that antibody levels will remain well above levels induced by natural infection for 20 years.
