Solitary Extramedullary Plasmacytoma of the BladderPlasmacytoma is a rare B-lymphocyte neoplastic disorder that usually presents as the generalized disease multiple myeloma. Less than 5% of the cases present as a solitary mass of monoclonal plasma cells in the bone or soft tissue. Although solitary extramedullary plasmacytoma (SEP) may arise in any organ, it rarely involves the urinary bladder. A 67-year-old male without a history of multiple myeloma presented with urinary frequency and nocturia; he was later diagnosed with SEP of the bladder. The patient was initially treated with a course of radiation therapy without symptomatic improvement; therefore a chemotherapy regimen consisting of lenalidomide and dexamethasone was subsequently given for six cycles. SEP usually carries a better prognosis and higher cure rate than solitary plasmacytoma of bone, as SEP is radiation sensitive. The role of adjuvant chemotherapy in the treatment of SEP that is resistant to radiation therapy is not clear, since most of the recommendations have been derived from the experience of head and neck SEP. The literature also lacks recommendations for choice of a chemotherapy regimen and surveillance of isolated bladder plasmacytoma. Here we present the first case of a radiation-resistant solitary plasmacytoma of the bladder that was successfully treated with lenalidomide and dexamethasone with successful clinical remission.

Response of the Normal Eye to High Dose RadiotherapyRadiation therapy of tumors near the eye or optic nerves often requires incidental irradiation of these structures, even when they are not clinically involved by tumor. Depending on the radiation treatment volume and dose required, radiation injury to the lens, lacrimal apparatus, retina, or optic nerve may result. The time to expression and severity of injury are dose-dependent. This paper reviews the results of 157 patients who were followed for a minimum of 3 years after radiotherapy for primary extracranial tumors at the University of Florida, in which the lacrimal gland, lens, retina, and/or optic nerve(s) received irradiation. This review shows that, after treatment at approximately 1.8 to 2.0 Gy per fraction, the incidence of severe dry-eye syndrome, retinopathy, and optic neuropathy appears to increase steeply after doses of 40, 50, and 60 Gy, respectively.

Management of Hepatocellular CarcinomaThe article, “Management of Hepatocellular Carcinoma,” by Drs. Nakakura and Choti, is an excellent, comprehensive overview of the treatment modalities used for one of the most challenging cancers. The thoroughness of this review underscores the current frustration of the clinician in the management of this disease and the inadequacies of available therapies. The authors list more than 17 treatments for the various stages of this disease. However, if any one of the therapies mentioned offered cure to a majority of patients, there would be little need for more review articles or randomized controlled trials. There are few cancers that command such a vast array of differing therapies from so many different specialties.

Synergizing Radiation Therapy and Immunotherapy for Curing Incurable CancersRadiation is often considered immunosuppressive, an activity that is most likely a result of the complex interplay of hormesis and the abscopal effect. The abscopal effect, also called the “distant bystander” effect, is a paradoxical effect of radiation on cellular systems whereby local radiation may have an antitumor effect on tumors distant from the site of radiation.

Management of Congenital Vascular Lesions of the Head and NeckCongenital vascular lesions are often misdiagnosed and, for the most part, left untreated.

The Prostate Cancer Intervention Versus Observation Trial (PIVOT)The Prostate Cancer Intervention Versus Observation Trial (PIVOT) is a randomized trial designed to determine whether radical prostatectomy or expectant management provides superior length and quality of life for men with clinically localized prostate cancer. Conducted at Department of Veterans Affairs and National Cancer Institute medical centers, PIVOT will enroll over 1,000 individuals less than 75 years of age. The primary study end point is all-cause mortality. Secondary outcomes include prostate cancer- and treatment-specific morbidity and mortality, health status, predictors of disease-specific outcomes, and cost-effectiveness. Within the first 3 years of enrollment, over 400 men have been randomized. Early analysis of participants' baseline characteristics indicate that enrollees are representative of men diagnosed with clinically localized prostate cancer throughout the United States. Therefore, results of PIVOT will be generalizable. These results are necessary in order to determine the preferred therapy for clinically localized prostate cancer. [ONCOLOGY 11(8):1133-1143, 1997]

EGFR Inhibitors in Lung CancerTargeted therapies inhibiting the epidermal growth factor receptor(EGFR) have been introduced in the treatment of patients with advancednon–small-cell lung cancer (NSCLC). Many inhibitors of theEGFR have been developed, targeting either the extracellular receptordomain with antibodies or the intracellular tyrosine kinase bindingdomain with small molecules. The tyrosine kinase inhibitor (TKI)gefitinib (Iressa) was the first targeted drug to be registered for thetreatment of NSCLC after failure of chemotherapy. Given concurrentlytogether with platinum combination chemotherapy both TKIs gefitiniband erlotinib (Tarceva) failed to increase activity. Sequential targetedtherapy after chemotherapy is currently being investigated further. Studieswith the monoclonal antibody cetuximab (Erbitux) combined withchemotherapy are ongoing. Side effects of the small molecules aremainly skin rash and diarrhea, whereas the antibodies do not give diarrhea.Selection of patients, based on molecular markers and patientcharacteristics, has become an important issue for the further developmentof these drugs, given there is activity in a relatively small group ofpatients with NSCLC. Newer drugs inhibiting more than one receptorpathway are being investigated in order to find activity in a broadergroup of patients.
