2010 has been another prolific year in breast cancer research with a number of original observations bringing us closer to personalized care. Studies with novel targeted agents in defined breast cancer subgroups have revealed exciting developments and highlight the importance of patient selection.
2010 was not a year of survival breakthroughs in hematologic malignancies. However, in Hodgkin's disease and multiple myeloma new therapies emerged as the standard of care and nilotinib may be considered the treatment choice for newly diagnosed chronic myeloid leukemia.
Advances in non-small-cell lung cancer over the past decade have resulted in new treatments with minimal toxic effects and dramatic clinical benefits. 2010 saw continued advancement in our understanding of the molecular genetics of lung cancer and of specific targeted inhibitors with remarkable clinical benefit in selected populations.
Randomized phase III trials have established new standards of care for advanced biliary cancer, HER2-positive advanced gastric or gastro-esophageal junction cancer, and preliminarily, for metastatic pancreatic cancer. There is now a validated predictive biomarker to guide use of adjuvant chemotherapy in patients with stage II colon cancer.
Outcomes for patients with oropharyngeal cancer are determined by their tumor characteristics and associated demographics. The role of human papilloma virus-related disease for prognosis and outcomes with chemoradiotherapy is being more clearly defined. EGFR inhibitors are used in conjunction with radiotherapy, and the importance of optimizing radiation quality and minimizing toxicity is the focus of ongoing studies.
MicroRNAs (MiRNAs) can act as oncogenes or tumor-suppressor genes and have differential expression in tumor progression and metastasis. MiRNAs are involved in a number of pathways that contribute to metastasis, including migration, invasion, cell proliferation, epithelial-to-mesenchymal transition, angiogenesis and apoptosis. This Review provides a summary of the existing data documenting these functions and describes the clinical utility of miRNAs as prognostic and predictive biomarkers and their potential therapeutic applications in advanced cancer.
A personalized treatment approach for lymphoma has potential to improve treatment responses. In this Review, Anas Younes summarizes the current development status of novel agents for lymphoma and discusses strategies to move the field forward.
Selectively targeting cancer stem cells with novel therapeutics is gaining importance because disease recurrence after treatment-induced remissions is a major cause of morbidity and mortality. This Review discusses the pathways that are active during development, specifically the Wnt, Notch, and Hedgehog pathways, and the clinical development of therapeutic agents that target these pathways.
Men with locally advanced or high-risk prostate cancer may benefit from combined modality strategies. This Review discusses the approaches and rational for preoperative and intraoperative radiotherapy and compares them with the utility of postoperative radiotherapy. The urgent need for novel biomarkers for selection purposes is highlighted.
Radio-embolization using radioactive microspheres allows the delivery of high-dose internal radiotherapy to malignant tumors of the liver. The surrogate for measuring flow dynamics for radio-embolization planning does not best represent treatment efficacy. Therefore, Morgan et al. propose that imaging protocols sensitive to changes in vasculature are likely to represent useful predictive markers of malignant lesions that could benefit from radio-embolization.
