Hepatocellular carcinoma (HCC) is one of the world’s most common cancers. It is closely associated with cirrhosis, especially that due to viral hepatitis. The incidences of viral hepatitis and HCC are rising steadily in the United
Kaposi’s sarcoma (KS) is the most common malignancy associated with the acquired immunodeficiency syndrome (AIDS). Recent years have witnessed a decline in the overall incidence of AIDS-related KS, as well as a greater
The article by Damjanov and Meropol elegantly outlines the rationale behind the preclinical development of several potential new oral chemotherapy options for patients with advanced colorectal carcinoma and the available data from clinical trials in advanced colorectal cancer that evaluated the activity and safety of these agents. The authors relate the history of fluorinated pyrimidine therapy in colorectal cancer and the pharmacologic challenges to delivering effective oral therapy in a such a way that the chemistry behind the processes becomes readily intelligible. They note that the erratic absorption and blood levels associated with orally administered fluorouracil (5-FU) led to the current approaches to oral therapy.
Cross-sectional imaging of the abdomen in oncology patients presents unique challenges and opportunities. A close working relationship between the oncologist and radiologist is essential for the exchange of the clinical and

In this short review, we describe two new liver-specific contrast agents for MRI that are in clinical development. The main differences among the liver-specific contrast agents available at present are also discussed briefly.
The criteria for successfully resecting pulmonary metastasis have not changed since they were originally described by Ehrenhaft in 1958. They are (1) that the primary tumor site has been removed without evidence of local recurrence, (2) that no extrathoracic organ metastasis exists, and (3) that pulmonary disease has been completely removed without compromising pulmonary function.

Heidelberger and associates synthesized fluorouracil (5-FU) in 1957 after observing that rat hepatomas utilized radiolabeled uracil more avidly than malignant tissues. For the past 40 years, 5-FU has been extensively investigated in various schedules, in combination with biochemical modulators, and for a variety of malignancies.
Total laryngectomy is the surgical procedure traditionally used to treat patients with advanced-stage cancer of the larynx. The impairments resulting from removal of such a small organ are, indeed, profound. They include

The borderline category of ovarian tumors is one of the most controversial topics in gynecologic oncology and pathology, and is confusing to both clinicians and patients. Although numerous reviews have appeared in the literature, most of them rehash the prevailing views on borderline tumors without critically evaluating the published data that allegedly validate some rather puzzling and perplexing notions. For example, although these tumors are considered to be a subset of carcinoma, most patients are cured even when they have “metastatic” disease that has been inadequately treated. In addition, reports cite recurrence and death as late as 39 years after the diagnosis of tumors that appear histologically bland and noninvasive.
Dr. Mitsuyasu has been doing clinical research in patients with AIDS-related Kaposi’s sarcoma (KS) since the beginning of the AIDS epidemic, and his review reflects this breadth of experience. It provides a well-rounded and up-to-date assessment of the pathophysiology, evaluation, and treatment of AIDS-related KS that should be a useful guide for practicing physicians.

In his excellent review, Dr. Mitsuyasu correctly highlights the three most important ingredients that play a role in the pathogenesis of acquired immunodeficiency syndrome (AIDS)-related Kaposi’s sarcoma (KS)—Kaposi’s sarcoma herpesvirus/human herpesvirus type 8 (KSHV/HHV-8); altered expression and response to cytokines; and stimulation of KS growth by the human immunodeficiency virus (HIV)-1 trans-activating protein, Tat. Recent studies have provided tremendous insight into the process whereby KSHV/HHV-8 creates the inflammatory-angiogenic state that characterizes KS.

In their article, Chao and Goldberg provide a concise overview of the literature on pulmonary metastasectomy for sarcoma, including a brief history of the procedure, guidelines for preoperative evaluation, conduct of the operation, and probable outcomes achieved. Several points that they review deserve further discussion.

Drs. Mark Singer and Eric Blom revolutionized the process of speech rehabilitation following total laryngectomy with their introduction of the tracheoesophageal puncture and insertion of a duck bill prosthesis.[1-5] The physiologic principles of the procedure are obvious, the surgical technique is simple, and the results in terms of fluent speech production are immediate and quite satisfactory. Dr. Blom is to be complimented for providing in this article, a succinct summary of the “current methods” available for speech rehabilitation for a patient facing total laryngectomy.

In his article, Dr. Mitsuyasu concisely reviews a large body of data concerning the etiology, pathogenesis, epidemiology, and treatment of Kaposi’s sarcoma (KS) in the setting of the human immunodeficiency virus (HIV) infection. As he correctly points out, effective highly active antiretroviral therapy (HAART), with its consequent improvements in immune function and decrease in production of viral and cytokine cofactors that promote KS growth, has been partly responsible for the decline of KS incidence in areas with ready access to HIV therapy.

Damjanov and Meropol review the status of several oral fluoropyrimidine drugs that are currently undergoing clinical testing for the treatment of colorectal cancer. Meta-analysis indicates an 8% improvement in the overall response rate and a survival advantage of 0.8 months with infusional vs bolus fluorouracil (5-FU)—arguably small differences.

Ovarian tumors of low malignant potential (LMP) would benefit from a new name, not to mention a deeper understanding of their biology, effective treatment, and a framework within which they can be studied. Fortunately, for a pathologic entity that is poorly understood and also is unresponsive to current therapy, most LMP ovarian tumors carry a benign prognosis.
With worldwide use of cellular phones rising exponentially, a team of Swedish medical investigators is raising renewed concerns about the link between brain tumors and cell phones in a new, peer-reviewed article posted on the Medscape
In their literature survey, Drs. Chao and Goldberg reach the conclusion that surgical metastasectomy is the clear treatment of choice and should be the standard of care for patients with pulmonary recurrences of soft-tissue sarcoma. It is assumed that survival without this operation is negligible, even while there are no survival statistics for sarcoma patients who are eligible for metastasectomy and who choose to forgo this option.
