Big Data: Not Really the Same as Level 1 Data

January 15, 2015

The problem with large sets of data is the risk of the “GIGO” principle-viz. garbage in, garbage out-and it requires a very careful and thoughtful investigator to rule out the many errors of large-scale data capture.

In Germ Cell Cancer, Are We at the End of the Chemotherapy Era? No-Targeted Therapies Have Not Heralded Its Demise

November 15, 2013

Germ cell tumors (GCT) are an exemplar of the successful use of chemotherapy and of the successful interplay of phase II and phase III trials. The biggest contributor to cure in metastatic GCT is cisplatin-based chemotherapy, unchallenged after more than 30 years.

Remembering Old Lessons in Prostate Cancer: Avoiding Errors 'in PARPituity'

July 15, 2013

The “experts” should maintain a stringent standard regarding what merits further development and reconsider carefully and critically the available data before committing to PARP inhibition, attacks on the PI3K pathway, and vasoactive agents in prostate cancer.

Prostate Cancer: What Did We Learn From the 2012 Annual Scientific Meeting of ASCO?

December 19, 2012

This review summarizes recent findings in clinical prostate cancer research reported at the 2012 Annual Scientific Meeting of the American Society of Clinical Oncology (ASCO) and addresses their relevance to clinical practice.

Spiraling Costs: Who Will Address the Role of Medicolegal Drivers?

June 29, 2012

I think it is a real shame that inside the Beltway, both sides of the political arena have had neither the wisdom nor the courage to recognize and address the fact that medicolegal drivers will continue to push costs upward until someone takes the lead in tackling this issue.

Controversies in the Management of Localized Prostate Cancer: After the Rhetoric

September 11, 2009

For the September and October issues of ­ONCOLOGY, we have assembled a team of experts in the diagnosis and management of early-stage prostate cancer-ie, disease that has not clinically metastasized at first presentation, and which is theoretically curable-and have asked them to take a position on optimal patterns of care.

Wealth of Riches in RCC Treatment: How Do We Avoid 'Devaluing the Dollar'?

September 01, 2007

The treatment of metastatic renal cell carcinoma (RCC) has changed dramatically over the past few years. An improved understanding of the biology of RCC has resulted in the development of novel targeted therapeutic agents that have altered the natural history of this disease. In particular, the hypoxia-inducible factor (HIF)/vascular endothelial growth factor (VEGF) pathway and the mammalian target of rapamycin (mTOR) signal transduction pathway have been exploited. Sunitinib malate (Sutent), sorafenib tosylate (Nexavar), bevacizumab (Avastin)/interferon alfa, and temsirolimus (Torisel) have improved clinical outcomes in randomized trials by inhibiting these tumorigenic pathways. Combinations and sequences of these agents are being evaluated. Other novel multitargeted tyrosine kinase inhibitors (pazopanib and axitinib) and mTOR inhibitors (everolimus) are in clinical development. Recently reported and ongoing clinical trials will help further define the role of these agents as therapy for metastatic RCC.

Disparities in Cancer Care: Challenges and Solutions

April 01, 2007

There is an increased incidence of cancer in minority populations, accompanied by reduced survival. This review will address specific areas of disparity in cancer care, including prevention, diagnosis, treatment, and outcomes, and will consider steps toward resolving these issues.
