Social Well-Being and Cancer SurvivorshipBill, 53 years old and a 3-year survivor of non-Hodgkin’s lymphoma, reflects on his ongoing journey as a cancer survivor: “I was very sick and treatment was very rough, complete with a severe allergic reaction that was difficult to diagnose for a long time. But I made it through to the other shore…remission. Since then, I’ve been trying to rebuild a new life…Living with an 18-year-old [son], I can see how in some ways I’m in a parallel universe…Both of us are looking out at the world before us, at all the many possible options...trying to figure out what we want tomorrow to look like.

Novel Concepts in Radioimmunotherapy for Non-Hodgkin's LymphomaTositumomab/iodine-131 tositumomab (Bexxar) and ibritumomab tiuxetan (Zevalin) are radioimmunoconjugates targeting the CD20 antigen. Both agents are approved in the United States for use in relapsed or refractory, indolent or transformed, B-cell lymphoma. These agents are well tolerated and have the highest levels of single-agent activity observed in these histologies. This review will summarize the key trials that led to approval of both I-131 tositumomab and ibritumomab tiuxetan, and then focus on four novel therapeutic concepts in radioimmunotherapy: retreatment, therapy of de novo indolent lymphoma, therapy of aggressive histologies, and incorporation in high-dose therapy programs utilizing autologous stem cell support.

MRI and Breast Cancer: Role in Detection, Diagnosis, and StagingIncreasing experience with magnetic resonance imaging (MRI) has raised important questions about how it should be used in breast cancer screening, and for presurgical evaluation and posttherapy follow-up of women with this disease. Overall, the availability of MRI as an adjunct to mammography and ultrasound offers clear clinical benefit to women at increased risk of breast cancer development due to BRCA1 and BRCA2 mutations, and to women presenting with axillary adenopathy and an occult primary breast tumor. In contrast, its benefit for routine selection of breast conservation or further assessment of lobular carcinoma in women of average risk has not been demonstrated.This article reviews the use of MRI in these settings, with an emphasis on the clinical outcomes that have been observed to date.

Commentary (Boxer): Management of Sexual Dysfunction After Prostate BrachytherapyThe current ONCOLOGY articleby Drs. Merrick, Wallner,and Butler is a valuable additionto the literature. An estimated189,000 American men were diagnosedwith prostate cancer in 2002,and 30,200 died of the disease, makingit the most common cancer amongmen, and the second most commoncause of cancer death.[1] The treatmentshave led to a high rate of cure,but the results of treatment oftencause a reduction in quality of life.

Targeting the Proapoptotic Factor Bcl-2 in Non-Hodgkin's LymphomaBcl-2 functions as a key survival factor for lymphocytes and is highlyexpressed in a majority of non-Hodgkin's lymphomas. The ability ofoblimersen sodium (Genasense, previously known as G3139) to targetbcl-2 messenger RNA and decrease Bcl-2 protein levels has the potentialto enhance the activity of cytotoxic chemotherapy. Pretreatmentwith oblimersen followed by cyclophosphamide (Cytoxan, Neosar)markedly improved survival relative to single-agent cyclophosphamidein a murine xenograft model. Oblimersen has also enhanced the cytotoxicityof a variety of other agents against non-Hodgkin's lymphoma,including etoposide, rituximab (Rituxan), and alemtuzumab (Campath).An initial phase I study of oblimersen in non-Hodgkin's lymphomademonstrated modest single-agent activity. Recent reports suggest thatoblimersen may add to the activity of R-CHOP (rituximab-cyclophosphamide/doxorubicin/vincristine/prednisone) in previously untreatedmantle cell lymphoma and to rituximab alone in a variety of subtypesof relapsed non-Hodgkin's lymphoma. Additional studies in both treatment-naive and relapsed patients will define the role of oblimersen inthe treatment of non-Hodgkin's lymphoma.

BMT for Severe Autoimmune Diseases: An Idea Whose Time Has ComeMost patients with autoimmune diseases are thought to have a a normal life expectancy, and thus are treated conservatively. However, these diseases have a diverse clinical course. A small subset of patients have "severe autoimmune diseases," or SADS, which are rapidly progressive and are associated with early mortality. If patients with SADS can be identified before they develop irreversible organ damage, aggressive intervention would be indicated. Consequently, patients with SADS are now being enrolled in experimental protocols of immune ablation and hematopoietic stem-cell rescue (ie, bone marrow transplantation [BMT]) at several US institutions. For various reasons, including the high cost of BMT, it will probably be years before the benefits, if any, of this procedure are known. [ONCOLOGY 11(7):1001-1017, 1997]

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]

Current Management of Unusual Genitourinary Cancers: Part IIOften overshadowed by more common genitourinary cancers, such as prostate, testicular, and kidney cancers, penile and urethral cancers nonetheless represent difficult treatment challenges for the clinician. The management of these cancers is slowly evolving. In the past, surgery, often extensive, was the treatment of choice. Recently, however, radiation and chemotherapy have begun to play larger roles as initial therapies, with surgery being reserved for salvage. With these modalities in their treatment armamentarium, oncologists may now be able to spare patients some of the physical and psychological sequelae that often follow surgical intervention without compromising local control and survival. Part 1 of this two-part article, published in last month’s issue, dealt with cancer of the penis. This second part focuses on cancer of the urethra in both females and males.

Bone Biology and the Role of the RANK Ligand PathwayBone renewal is essential for bone strength. During childhood and early adulthood, bone formation prevails over bone resorption, as bones increase in size and strength. Peak bone mass is achieved during the third decade in life, with a higher peak bone mass being protective against osteoporosis later in life.[1] Bone loss is most prominent in women at menopause due to the effects of a natural decline in estrogen levels. However, bone mass begins to decrease with age, and bone loss is most prominent in women at menopause due to the effects of a natural decline in estrogen levels.[2]

Her excellent article summarizes four important studies, identifies the research design problems and questions raised by these and other studies, and proposes a model for how chemohormonal therapy might affect cognitive functioning and quality of life (see Figure 1 of her article). Finally, she identifies how actual, as well as potential, cognitive impairment might influence patient decisions and care (the author’s Table 1).
