Although some evidence exists to support the use of clinical factors such as performance status and weight loss to predict response and toxicity to therapy in non-small cell lung cancer (NSCLC) patients, researchers have shown little prospective data on the use of molecular markers to facilitate selection of specific chemotherapy or new molecularly targeted agents in this patient population. Breast cancer exemplifies the growing role that molecular markers are playing, not only as prognostic factors, but also in predicting response to targeted treatments such as hormonal therapy, and more recently, trastuzumab (Herceptin). Although several studies have examinedmolecular markers in lung cancer and have shown promising potential value, these studies were retrospective and require prospective validation. To identify molecular markers that reliably predict response and to be able to individualize cytotoxic and targeted therapy for NSCLC patients are the ultimate goals of future trials. This article focuses on a selected number of promising markers under study in lung cancer, including those thought to play roles in response to DNA damaging chemotherapy (excision repair cross-complementing [ERCC1], xeroderma pigmentosum group D [XPD]), taxane resistance (-tubulin III), antimetabolite therapy (RRM1), irinotecan metabolism (UGT1A1) and epidermal growth factor receptor (EGFR) pathway inhibition. To date, none of these markers can be recommended for routine use in clinical practice.

The NCCN Guidelines for Prostate Cancer provide multidisciplinary recommendations on the clinical management of patients with prostate cancer. This report highlights notable recent updates. Radium-223 dichloride is a first-in-class radiopharmaceutical that recently received approval for the treatment of patients with symptomatic bone metastases and no known visceral disease. It received a category 1 recommendation as both a first-line and second-line option. The NCCN Prostate Cancer Panel also revised recommendations on the choice of intermittent or continuous androgen deprivation therapy based on recent phase III clinical data comparing the 2 strategies in the nonmetastatic and metastatic settings.

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Prostate Cancer provide multidisciplinary recommendations for the clinical management of patients with prostate cancer. These NCCN Guidelines Insights highlight notable recent updates. Abiraterone acetate is a first-in-class hormonal agent that represents a new standard of care for patients with metastatic castration-recurrent prostate cancer who have previously received docetaxel (category 1 recommendation). Abiraterone acetate also received category 2B recommendations in the prechemotherapy setting for asymptomatic patients or symptomatic patients who are not candidates for docetaxel. The NCCN Prostate Cancer Panel also added new indications for existing agents, including the option of sipuleucel-T as second-line therapy. In addition, brachytherapy in combination with external beam radiation therapy with or without androgen deprivation therapy is now an alternative for patients with high-risk localized tumors or locally advanced disease.
