Drs. Uzair Chaudhary and GeraldHull provide a comprehensivereview of the role ofcytoreductive surgery in metastaticrenal cell carcinoma. This controversialtopic has been debated for manyyears. Metastatic renal cell carcinomacontinues to be a chemotherapyresistanttumor with a poor prognosis.About 30% of newly diagnosedpatients present with metastatic disease.In the metastatic setting, themost recognized treatment modalitiesinvolve the biologic agents interferon-alpha and interleukin-2 (IL-2,Proleukin). They produce an objectiveresponse rate of about 10% to15%, with approximately 5% of patientsachieving a durable completeresponse.

In this issue of ONCOLOGY,Chaudhary and Hull succinctlysummarize historical trends andcurrent thinking regarding the role ofcytoreductive nephrectomy in patientswith metastatic kidney cancer.Before the era of immunotherapy,there was little evidence that the naturalhistory of metastatic renal cellcarcinoma was improved by cytoreductivenephrectomy.[1] Patientswith metastatic cancer generally diefrom complications related to theirsites of tumor spread and not fromthe primary tumor; thus, on face value,it seems illogical to surgicallyremove the primary tumor in thesepatients.

Metastatic renal cell carcinoma is a devastating disease associatedwith poor survival. Immunotherapy is the mainstay of treatment, butresponse rates are low. The role of cytoreductive surgery in thepresence of metastatic disease is evolving. From both retrospective andrecently published randomized clinical trials, it is now apparent thatamong patients with metastatic renal cell carcinoma and good performancestatus, cytoreductive surgery followed by immunotherapy improvessurvival. However, this approach is likely to be detrimental inpatients with poor performance status. Clinical trials of novel agentsremain a priority in this disease.

FRAMINGHAM, Massachusetts-Genzyme Molecular Oncology has launched a phase I/II vaccine trial in advanced kidney cancer. The vaccine is made by combining the patient’s own cancer cells with dendritic cells using an electrical fusion approach. Up to 20 patients will be enrolled at Beth Israel Deaconess Medical Center and the Dana-Farber Cancer Institute, Boston.

Despite significant advances in the treatment of a variety of malignancies, highly effective therapies for most patients with metastatic renal cell carcinoma or metastatic melanoma are rare. Traditional oncologic treatment methods, such as

Interleukin-2 (IL-2, Proleukin) is one of the most effective agents in the treatment of metastatic renal cell carcinoma and metastatic melanoma. High-dose IL-2 therapy produces overall response rates of 15% to 20%;

Although high-dose interleukin-2 (IL-2, Proleukin), a highly toxic agent used in the treatment of renal cell carcinoma and melanoma, was initially associated with treatment-related mortality, it can, in the appropriate

Flavopiridol [2-(2-chlorophenyl 5 ,7-dihydroxy-8-[cis-(3-hydroxy-1-methyl-4-piperidinyl)-4H-1-benzopyran-4-one, hydrochloride] is a semisynthetic flavone with a novel structure compared with that of polyhydroxylated flavones, such as quercetin and genistein.[1] It is derived from rohitukine, an alkaloid isolated from the stem bark of Dysoxylum binectariferum, a plant indigenous to India.[2] Originally synthesized and supplied by Hoechst India Limited, flavopiridol is provided to the Division of Cancer Treatment and Diagnosis of the National Cancer Institute (NCI) by Aventis Pharmaceuticals, Inc.

Phase II studies of single-agent docetaxel (Taxotere) yielded promising results in advanced or metastatic transitional cell carcinoma (TCC) of the urothelium. Antitumor responses have been demonstrated in previously treated and chemotherapy-naive TCC patients, as well as in a subgroup of patients with renal impairment unable to receive traditional cisplatin-based regimens.

A 68-year-old man is referred for further evaluation and treatment of jaundice. He describes pruritus, intermittent mild midabdominal discomfort, and progressive weight loss. There is no history of fever. His history is significant for renal cell carcinoma with pulmonary metastasis.

ANAHEIM, California-Percutaneous radiofrequency ablation, which is FDA-approved for treating liver and soft tissue neoplasms, may also be useful in renal cell carcinoma, according to several reports from the American Urological Association annual meeting.

SAN FRANCISCO-Trials employing outpatient use of subcutaneous (SC) interleukin-2 (IL-2, Proleukin) in lower doses suggest that the overall response rate in metastatic renal cell carcinoma is adversely affected by the decrease in dose or the subcutaneous route of administration.

Preliminary results of a phase III trial of high-dose recombinant human interleukin-2 (IL-2, Proleu kin) demonstrated increased response rates with a longer median duration, compared to outpatient subcutaneous IL-2 in conjunction with

BMS-247550 is a methyl, semi-synthetic analog of the natural product epothilone B. Provided to the National Cancer Institute (NCI) by Bristol-Myers Squibb, BMS-247550 was chosen for clinical development because it demonstrated

With the understanding of the mechanism of malignant transformation has come the knowledge that oncogene products are frequently growth factors, growth factor receptors, or elements of growth factor signal-transduction pathways. Overexpression

A pilot study was performed at The University of Texas M. D. Anderson Cancer Center to determine the feasibility of using thalidomide in a population of renal-cell carcinoma patients who had progressive disease despite chemotherapy and immunotherapy. Metastatic renal-cell carcinoma patients with adequate oral function were entered onto a study after signing an internal review board-approved informed consent. There were no exclusion criteria for prior therapy. Nineteen previously treated patients and one untreated patient with progressive renal-cell carcinoma received oral thalidomide as a single agent. The starting dose was 200 mg and the dose was increased by 100 to 200 mg every week until it reached 1,200 mg/d. Response was assessed on the basis of a radiographic reduction of the metastatic sites involved. A case report describing one of the patients involved in the pilot trial is included.

Surgical resection remains the cornerstone of management for localized renal cell carcinoma. No effective postsurgical adjuvant therapy has been established for

Drs. Wolchok and Motzer provide a succinct, timely review of the diagnosis and management of renal carcinoma. The article leads us to ask a number of questions: What factors account for the major increase in the incidence of renal carcinoma? How has surgical management evolved with the advent of newer operative techniques? What role, if any, does chemotherapy play in the treatment of this disease? What is the current status of and future outlook for immunotherapeutic approaches?

BETHESDA, Md-Some kidney cancer patients in an ongoing phase II trial of an experimental antiangiogenesis monoclonal antibody have shown improvement. The randomized, three-arm study by National Cancer Institute researchers compares two different doses of the drug against a placebo.

Often 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.
