Dr. Schuchter's article explores the theoretical and practical aspects underlying the concept of cytoprotection, which has been recently introduced into the therapeutic armamentarium. Cytoprotection is contrasted with the related strategy of rescue, which has been widely applied since the cytokines granulocyte colony-stimulating factor (G-CSF, filgrastim [Neupogen]) and granulocyte-macrophage colony-stimulating factor (GM-CSF, sargramostim [Leukine, Prokine]) obtained FDA approval.

Ferrell and Hassey Dow summarize research on the domains of quality of life (QOL) most important to the adaptation of survivors, and offer insights about possible interventions to support and promote this adaptation. In addition, they note that the field is poised to make great progress in understanding the concerns and needs of survivors, due, in part, to the establishment of the Office of Cancer Survivorship, an institutional home at the National Cancer Institute (NCI) that will coordinate and promote research on this critical topic.

Small intestinal epithelial cells are remarkably resistant to the development of benign or malignant neoplasms. Why small-bowel adenocarcinomas are so rare compared to colorectal adenocarcinomas is unknown. Thus, the work of Neugut et al is important, as they provide an excellent overview of the current knowledge of this unique tumor, and the problems and limitations encountered in such research.

Thanks to advances in cancer diagnosis and treatment, there are now more than 10 million cancer survivors in the United States. Successful treatment of cancer has resulted in increased demands on survivors and has had diverse effects on the quality of life (QOL) of patients and their families. A model of QOL encompassing dimensions of physical, psychological, social, and spiritual well-being has been applied to illustrate the multidimensional needs of cancer survivors and the necessity of comprehensive care extending over the long term. Data from a recent survey of members of the National Coalition of Cancer Survivorship (NCCS) is presented, along with a summary of issues compiled by the NCCS that merit future attention.

For the sake of the 7.4 million Americans alive today who have a history of cancer, Ferrell and Hassey Dow's paper is important. Understanding more about the problems and issues faced by these individuals and their families, as well as identifying effective ways to ensure that they experience a high quality of survival, are significant issues for cancer care and research.

Of all the digestive tract tumors, small-bowel cancers are the least common. Why should we study these rare tumors, and what, if anything, can we learn from them? Sometimes the absence of an important event can provide the answer to a difficult problem. For example, consider the famous Sherlock Holmes mystery story, "Silver Blaze," in which the master sleuth solved a challenging case, simply because the watchdog didn't bark when he should have, implying that the murderer was well known to the dog.[1]

Even though the small intestine contains 90% of the gastrointestinal tract mucosa and is located between the stomach and large intestine, two organs with a high cancer incidence, adenocarcinoma of the small intestine is 1/50th as common as adenocarcinoma of the large bowel. In several other respects, small-intestinal adenocarcinoma resembles large bowel adenocarcinoma; eg, it arises from adenomatous polyps, co-occurs in the same individuals, and has a similar pattern of incidence rates by country. Small-intestinal adenocarcinoma is diagnosed prior to surgery in only about 50% of cases and often occurs in conjunction with small bowel obstruction. The mainstay of treatment is surgery; prognosis depends on stage at presentation. Little is known about the use of radiotherapy and chemotherapy in this malignancy, but most physicians utilize therapeutic strategies modeled on the management of large-intestinal adenocarcinoma. Clarification of the reason for the low incidence of small-intestinal adenocarcinoma could lead to new interventions for the prevention of colorectal cancer. [ONCOLOGY 11(4):529-536, 1997]

Dr. DeAntoni has carefully reviewed the literature on age-specific reference ranges for prostate-specific antigen (PSA) in the diagnosis of prostate cancer and the controversy surrounding their use. Key to understanding of this debate are two fundamental concepts: (1) the definition of "clinically significant prostate cancer" and (2) the use of sensitivity and specificity, which is frequently obscured by the surrounding rhetoric. The assumption that all readers uniformly interpret the meaning of clinically significant prostate cancer and wish to achieve the same results by manipulating sensitivity and specificity is probably incorrect.

As the number of cases of newly diagnosed prostate cancer has risen dramatically in the United States during the past decade, the management of a rising prostate-specific antigen (PSA) level following definitive therapy has become an increasingly common dilemma. Waxman and associates provide a concise, focused review of many of the key issues and controversies surrounding this dilemma. Several of these issues warrant particular attention.

This article addresses an increasingly common dilemma: the finding of a rising prostate-specific antigen (PSA) level in an asymptomatic patient following radical surgery or radiation therapy for prostate cancer. The incidence of prostate cancer has skyrocketed, and the number of men being treated with radiation or radical prosta-tectomy has similarly increased. The most common basis for the initial diagnosis of prostate cancer is an elevated PSA. For the patient who is already sensitized to PSA as a diagnostic marker, it is extremely distressing to learn that his PSA is rising following radical treatment. This is particularly true for the patient who has experienced a treatment-related adverse effect on quality of life. For the treating physician, this all-too common scenario is disappointing and even guilt-laden.

Dr. DeAntoni provides a timely, critical review of the concept of age-specific prostate-specific antigen (PSA) ranges, as well as other frequently used attempts to improve the accuracy of serum PSA testing in the diagnosis of unsuspected prostate cancer. His review is complete, and his assessments of each of the modalities reflect not only the majority view but also realistic appraisals of the limitations of this less-than-perfect test.
