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.

Commentary (Sachelarie et al): Optimizing Adjuvant Chemotherapy in Early-Stage Breast CancerDrs. Perez and Muss provide acomprehensive review of therole of adjuvant chemotherapyin the management of breast cancerpatients. The benefits of anthracyclinevs nonanthracycline regimens are discussed,the taxanes are reviewed indetail, and data regarding dose intensity,dose density, and optimal numberof chemotherapy cycles areexplored. Data on newer agents andbiologic agents also are presented.Debate continues regarding the subsetsof patients who will derive thegreatest benefit from chemotherapyand which regimen is most appropriate.While the review indicates theefficacy of several regimens as definedby randomized clinical trials, itdoes not emphasize patient-specificfactors in determining the optimaltherapy for a given patient.

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]

Everyone's Guide to Cancer Supportive CareAs an oncologist, I am always on the lookout for good patient education material. This book, which is based on the experience of the Stanford Integrative Medicine Clinic Cancer Supportive Care Program, is a good choice for a highly literate, print-oriented patient or family member. The book is divided into five parts: (1) Cancer: Diagnosis, Information, and Treatment, (2) The Role of the Mind, (3) The Care of the Body, (4) Supportive and Social Services for Life and Death Issues, (5) Planning for the Future, and (6) Resources. These five parts are divided into 50 individual chapters covering specific topics, and the chapters are focused, concise, and practical.

Small-Cell Lung CancerSmall-cell lung carcinoma (SCLC) accounts for 20% to 25% of all new cases of lung cancer in the United States. It is estimated that approximately 42,000 new cases will occur in the United States in 1995 [1,2]. Of the various histologic types of lung cancer, small-cell is the most sensitive to chemotherapy and radiotherapy, yet overall outcome is poor, with only 5% to 10% of patients surviving 5 years from diagnosis.

Rare PTCLs: Treatment Lagging Behind Pathobiologic AdvancesPeripheral T-cell lymphomas, or PTCLs, represent an uncommon and biologically heterogeneous group of hematologic malignancies, accounting for less than 10% of all non-Hodgkin lymphomas worldwide, with marked geographic differences. Due to their low prevalence, variable clinical presentation and phenotypic heterogeneity, these lymphomas have historically been difficult to diagnose and categorize. Since the introduction of immunophenotyping and molecular genetic methods, as well as the development of comprehensive classification systems, there have been significant advances in diagnostic accuracy, classification, and our understanding of the biologic behavior of different PTCL subtypes. However, the molecular pathogenesis of most subtypes of PTCL remains incompletely understood, and treatment outcomes with conventional anthracycline-based chemotherapy regimens are generally significantly inferior to those in aggressive B-cell lymphomas.
