Commentary (Broaddus/Lu): Gynecologic Manifestations of Hereditary Nonpolyposis Colorectal CancerTraditionally, most hereditarynonpolyposis colorectal cancer(HNPCC) syndrome patientshave been identified and cared for bygastroenterologists, colorectal surgeons,and gastrointestinal medicaloncologists. Hence, the realization thatgynecologic tumors actually play amajor role in HNPCC has come relativelylate. Consequently, much of theclinical and basic science focus ofresearch in HNPCC has concentratedon colorectal cancer.

Modulation of Dose Intensity in Aerodigestive Tract Cancers: Strategies to Reduce ToxicityDr. Rich and colleagues present a compelling argument for the manipulation of temporal and spatial treatment parameters in chemoradiation programs. In essence, the authors address the shielding of normal tissues from the effects of cytotoxic agents. With respect to radiotherapy, this can be achieved via physical shielding by computer-generated dose algorithms using elaborate new planning technology (eg, intensity-modulated radiation therapy [IMRT]), chemical shielding with radioprotectants (eg, amifostine [Ethyol]), or temporal shielding by altered-fractionation schemes that exploit the differential alpha/beta ratios between tumor and normal tissue (eg, hyperfractionation).

Commentary (Malkowicz): Organ Preservation in Muscle-Invasive Bladder CancerThe most effective form of therapyfor muscle-invasive bladdercancer is radical surgery andurinary diversion. Numerous clinicalseries demonstrate stage-for-stage 5-and 10-year survival data that are betterthan that seen for other treatmentmodalities.[1] The widespread applicationof continent urinary diversionover the past 2 decades has furtheredthe acceptance of radical surgery, asit provides for the lost function ofvolitional storage and emptying ofurine. Even patients who undergo astandard ileal loop diversion generallytolerate it well and adapt to thealtered body image.[2]

Distant Effects of Cancer on the Nervous SystemParaneoplastic disorders of the nervous system are important to the practicing oncologist, because these syndromes, although uncommon, produce significant neurologic dysfunction and disability. The neurologic disorder may be the first manifestation of an unrecognized systemic malignancy, and appropriate diagnosis of the paraneoplastic disorder can lead to a focused search for an underlying cancer. Paraneoplastic disorders may involve any component of the central or peripheral nervous system, and diagnosis requires careful neurologic assessment. The diagnosis is made by recognition of clinical neurologic syndromes and the use of selected laboratory studies as indicated by the clinical picture. Over the past 10 years, the application of molecular biologic techniques to the study of these disorders has elucidated much about the mechanisms that cause neurologic injury. In most cases, disordered humoral and cellular immunity has been demonstrated, and the role of novel targets for autoimmune attack is being clarified. For some paraneoplastic disorders, treatment of the underlying tumor may lead to improvement of the neurologic disorder. For others, various forms of immunosuppressive therapy may be indicated. Unfortunately, for several of the more common paraneoplastic syndromes such as paraneoplastic cerebellar degeneration or limbic encephalitis, treatment is still unsatisfactory, and further research into the exact pathophysiology is clearly needed.

Treatment of Metastatic Colorectal Cancer: From Cytotoxic Agents to Molecular Agents and Multitargeted StrategiesColorectal cancer (CRC) is the third most common cancer and the second leading cause of cancer-related death in United States. For nearly 50 years, fluorouracil has been the only anticancer drug proven to benefit patients with metastatic CRC (mCRC), and it continues to be the backbone on which most treatment regimens are built. In the past 10 years, development of the topoisomerase I inhibitor irinotecan (Camptosar), the third-generation platinum analog oxaliplatin (Eloxatin), and the oral fluoropyrimidine capecitabine (Xeloda) advanced mCRC treatment and opened up an era of combination chemotherapy. More recently, monoclonal antibodies such as bevacizumab (Avastin), cetuximab (Erbitux), and panitumumab (Vectibix) have become available for use in mCRC treatment in combination with cytotoxic agents and as monotherapies. The addition of these targeted agents to the mCRC treatment armamentarium has resulted in more therapeutic options and improved treatment outcomes for the patients. The prospect of mCRC treatment is ever promising as more targeted agents such as vatalanib are being introduced and as intelligent combination regimens are being designed based upon a better understanding of pharmacokinetics. In this article we review various treatment options, including cytotoxic and targeted agents, currently available for patients with mCRC.
