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.

Bladder Cancer and Current Evidence for TreatmentOccult distant micrometastasis at the time of radical cystectomy leads predominantly to distant failures in patients with locally advanced muscle-invasive transitional cell carcinoma of the bladder. Cisplatin-based combination chemotherapy enhances survival in patients with metastatic urothelial cancer. Studies evaluating adjuvant chemotherapy have been limited by inadequate statistical power. However, randomized clinical trials have demonstrated a survival benefit for neoadjvuant cisplatin-based combination chemotherapy, which should be considered a standard of care. In addition, neoadjuvant therapy may assist in the rapid development of novel systemic therapy regimens, since pathologic complete remission appears to be a powerful prognostic factor for long-term outcomes. Patients who are either unfit for or refuse radical cystectomy may benefit from neoadjuvant chemotherapy with or without radiation to enable bladder preservation.

Cancer Management Chapter 36: Depression, anxiety, and deliriumAlthough many cancer patients cope well with their disease, psychiatric disorders occur in almost 50% of patients in the setting of malignancy. Untreated psychological and neuropsychiatric disorders can compromise quality of life as well as treatment compliance. Three behavioral syndromes that are often encountered in clinical practice will be discussed here: depression, anxiety, and delirium.

Can Patient Reporting Affect Radiation Pneumonitis?Radiation therapy (RT) is an important treatment modality for multiple thoracic malignancies. Incidental irradiation of the lungs, which are particularly susceptible to injury, is unavoidable and often dose-limiting. The most radiosensitive subunit of the lung is the alveolar/capillary complex, and RT-induced lung injury is often described as diffuse alveolar damage. Reactive oxygen species generated by RT are directly toxic to parenchymal cells and initiate a cascade of molecular events that alter the cytokine milieu of the microenvironment, creating a self-sustaining cycle of inflammation and chronic oxidative stress. Replacement of normal lung parenchyma by fibrosis is the culminating event. Depending on the dose and volume of lung irradiated, acute radiation pneumonitis may develop, characterized by dry cough and dyspnea. Fibrosis of the lung, which can also cause dyspnea, is the late complication. Imaging studies and pulmonary function tests can be used to quantify the extent of lung injury. While strict dose-volume constraints to minimize the risk of injury are difficult to impose, substantial data support some general guidelines. New modalities such as intensity-modulated radiation therapy and stereotactic body radiation therapy provide new treatment options but also pose new challenges in safely delivering thoracic RT.

Do Families Understand "Do Not Resuscitate" Orders?Do not resuscitate (DNR) orders have become an integral part of the care of the terminally ill patient. Often, the decision whether or not to resuscitate a patient in the event of cardiopulmonary arrest must be made by the patient's family members. This is a difficult decision that is made at an emotionally trying time. Our study investigated the satisfaction, understanding, and feelings of families who sign DNR orders for their relatives. We are not aware of any other studies that have evaluated this aspect of the DNR order.

Role of Radiation Therapy in Retroperitoneal SarcomasSoft-tissue sarcomas arising in the retroperitoneum represent an uncommon diagnosis, with approximately 600 new cases per year in the United States. Due to this small database, an assessment of the relative merits of different treatment strategies is not available. It is known is that patients with retroperitoneal sarcomas fare worse in terms of local control and disease-free survival than do patients with soft-tissue sarcoma of an extremity. The reasons for this are unclear but may be due, in part, to the large size of these tumors at diagnosis and the difficulty in obtaining adequate surgical margins.

Primary Cutaneous and Systemic Anaplastic Large Cell LymphomaAnaplastic large cell lymphoma (ALCL) is a biologic and clinically heterogenous subtype of T-cell lymphoma. Clinically, ALCL may present as localized (primary) cutaneous disease or widespread systemic disease. These two forms of ALCL are distinct entities with different clinical and biologic features. Both types share similar histology, however, with cohesive sheets of large lymphoid cells expressing the Ki-1 (CD30) molecule. Primary cutaneous ALCL (C-ALCL) is part of the spectrum of CD30+ lymphoproliferative diseases of the skin including lymphomatoid papulosis. Using conservative measures, 5-year disease-free survival rates are>90%. The systemic ALCL type is an aggressive lymphoma that may secondarily involve the skin, in addition to other extranodal sites. Further, systemic ALCL may be divided based on the expression of anaplastic lymphoma kinase (ALK) protein, which is activated most frequently through the nonrandom t(2;5) chromosome translocation, causing the fusion of the nucleophosmin (NPM) gene located at 5q35 to 2p23 encoding the receptor tyrosine kinase ALK. Systemic ALK+ ALCLs have improved prognosis compared with ALK-negative ALCL, although both subtypes warrant treatment with polychemotherapy. Allogeneic and, to a lesser extent, autologous stem cell transplantation play a role in relapsed disease, while the benefit of upfront transplant is not clearly defined. Treatment options for relapsed patients include agents such as pralatrexate (Folotyn) and vinblastine. In addition, a multitude of novel therapeutics are being studied, including anti-CD30 antibodies, histone deacetylase inhibitors, immunomodulatory drugs, proteasome inhibitors, and inhibitors of ALK and its downstream signaling pathways. Continued clinical trial involvement by oncologists and patients is imperative to improve the outcomes for this malignancy.

Current Status of Gastroenteropancreatic Tumor ManagementGastroenteropancreatic tumors, although relatively rare, present management problems that may last many years, in comparison with the usually more aggressive adenocarcinomas whose management may encompass a far briefer span of time. In general, 50% of such tumors are insulinomas, while gastrinomas comprise 25%, and nonfunctional tumors 20% VIPomas and glucagonomas are the predominant lesions of the remaining 5%. Clinical diagnosis is usually made on the presence of the classical symptom complex. In uncertain circumstances or covert presentations, the critical diagnostic biochemical test is plasma chromogranin A as well as measurement of the specific peptide.

Prostate Cancer and African-American MenMortality from prostate cancer is two to three times greater among African-American men between the ages of 50 and 70 than among American Caucasian men of similar ages. Also, African-Americans tend to present with more advanced tumors than their American Caucasian counterparts. This article explores differences between the two races that may account for the disproportionately high mortality among African-Americans and their more advanced disease stage at presentation. These include epidemiologic and histologic features of prostate cancer; clinical, biologic, and environmental factors; and barriers to health care. Various important issues that warrant further investigation are also highlighted. [ONCOLOGY 11(5):599-605, 1997]
