Management of Anal Cancer in the HIV-Positive PopulationSquamous cell anal cancer remains an uncommon entity; however,the incidence appears to be increasing in at-risk populations, especiallythose infected with human papillomavirus (HPV) and human immunodeficiencyvirus (HIV). Given the ability to cure this cancer using synchronouschemoradiotherapy, management practices of this disease arecritical. This article considers treatment strategies for HIV-positive patientswith anal cancer, including the impact on chemoradiation-inducedtoxicities and the role of highly active antiretroviral therapy in the treatmentof this patient population. The standard treatment has beenfluorouracil (5-FU) and mitomycin (or cisplatin) as chemotherapy agentsplus radiation. Consideration to modifying the standard treatment regimeis based on the fact that patients with HIV tend to experience greatertoxicity, especially when CD4 counts are below 200; these patients alsorequire longer treatment breaks. Additional changes to the chemotherapydosing, such as giving 5-FU continuously and decreasing mitomycin dose,are evaluated and considered in relation to radiation field sizes in an effortto reduce toxicity, maintain local tumor control, and limit need forcolostomy. The opportunity for decreasing the radiation field size andusing intensity-modulated radiation therapy (IMRT) is also considered,particularly in light of the fact that IMRT provides dose-sparing whilemaximizing target volume dose to involved areas. The impact of the immunesystem in patients with HIV and squamous cell carcinoma of theanus and the associated response to therapy remains unknown. Continuedstudies and phase III trials will be needed to test new treatment strategiesin HIV-infected patients with squamous cell cancer of the anus todetermine which treatment protocols provide the greatest benefits.

Commentary (Shuster): Delirium in Palliative CareMiriam Friedlander, YanaBrayman, and WilliamBreitbart have produced anexcellent review of delirium in thepalliative care setting. Their paper isthorough, readable, and thoughtful,and will be helpful to oncologists caringfor patients with advanced illness.I particularly like the fact that theauthors make it clear that delirium isnot only a very common complicationof advanced cancer, but that it isalso a major source of suffering anddistress for both patients and families.In view of the problems deliriumpresents and the frequency with whichdelirium arises as death approaches,this complication of advanced and terminalillness has received inadequateattention. My thanks and congratulationsgo to the authors for providingsuch a clear and helpful review of thischallenging clinical problem.

GM-CSF and IL-2 Combination as Adjuvant Therapy in Cutaneous MelanomaCytokines have been used in the treatment of patients with cutaneousmelanoma. Granulocyte-macrophage colony-stimulating factor(GM-CSF, sargramostim [Leukine]) leads to dendritic cell/macrophagepriming and activation, and also increases interleukin-2 (IL-2)receptor expression on T lymphocytes. IL-2 creates lymphokineactivatedkiller cells and tumor-infiltrating lymphocyte cells. In thisopen-label, single-arm study of 16 high-risk patients, we combined thesetwo agents to take advantage of their different but complementary functions.All patients underwent potentially curative surgery. Postoperatively,each patient received GM-CSF at 125 μg/m2/d subcutaneously(SC) for 14 days; this was followed by IL-2 at 9 million IU/m2/d SC for4 days, and then 10 to 12 days of no treatment. In addition, patientswho had large tumors that could yield over 100 million live tumor cellsreceived autologous melanoma vaccines. The duration of follow-upranged from 21 to 42 months (median: 27 months). During follow-up,five patients developed metastases. This program was carried out on anoutpatient basis, and no hospitalization was required. It was well toleratedwith minimal side effects. The combination treatment regimen ofGM-CSF and IL-2 with or without autologous vaccine used adjuvantlyappears to benefit high-risk melanoma patients; further clinical testingof this regimen is warranted.

Pituitary Adenomas: Current Methods of Diagnosis and TreatmentPituitary adenomas are benign neoplasms that can be effectively managed by a variety of therapeutic options. The clinician's goal in managing patients with these tumors should be to minimize the morbidity of each intervention used in diagnosis and treatment. Standard diagnostic interventions include MRI, hormonal assessment, and tissue diagnosis. Therapies include transsphenoidal surgery, external-beam radiotherapy, newer stereotactic irradiation techniques, and medical management. Appropriate treatment selection requires detailed knowledge of the expected outcomes and side effects of each option. Newer and perhaps less toxic treatment techniques are evolving and require further evaluation. [ONCOLOGY 11(6):791-796, 1997]

Historical and Methodological Perspectives on Cancer Outcomes ResearchOutcomes research is the study of the net effects of the health care process on the health and well-being of individuals and populations. It encompasses a wide breadth of issues, including measurement of patient preferences and health status, broadly referred to as quality of life. Evaluation of health-related quality of life in research studies has been facilitated by the development of a number of measurement tools. In addition to general health tools, cancer-related tools are available, some of which include cancer site-specific or symptom-specific measures. Preference assessment, from the perspective of the patient or general population, is necessary to incorporate quality of life into economic analyses. Various techniques are available to assign preference values to outcomes; metrics such as quality-adjusted life-years (QALYs) are then used to combine quality and quantity of life into a usable value for economic analyses. In the future, quality of life and economic measurements should be incorporated into phase III trials, effectiveness trials, and observational studies. [ONCOLOGY 9(Suppl):23-32, 1995]

Squamous Cell Carcinoma of the Anal MarginThis paper consists of a review of the literature on carcinoma of the anal margin, as well as the authors' institutional experience with this uncommon malignancy. The authors offer recommendations for treatment based on the size of the tumor, which correlates with the T-stage from the TNM or Union Internationale Contre le Cancer (UICC) staging systems. They recommend radiation alone or local excision for T1 lesions, radiation and elective nodal irradiation for T2 lesions, and chemoradiation, including irradiation of the primary tumor and inguinal and pelvic nodes, for T3 and T4 lesions.

Nonmyeloablative Preparative Regimens for Allogeneic Hematopoietic TransplantationHigh-dose myeloablative therapy with allogeneic hematopoietictransplantation is an effective treatment for hematologic malignancies,but this approach is associated with a high risk of complications.The use of relatively nontoxic, nonmyeloablative, or reduced-intensitypreparative regimens still allows engraftment and the generation ofgraft-vs-malignancy effects, is potentially curative for susceptiblemalignancies, and reduces the risk of treatment-related morbidity.Two general strategies along these lines have emerged, based on theuse of (1) immunosuppressive chemotherapeutic drugs, usually apurine analog in combination with an alkylating agent, and (2) lowdosetotal body irradiation, alone or in combination with fludarabine(Fludara).
