Validation of the FACT-BRM with interferon-alpha treated melanoma patients.

The somatic, neurocognitive, and psychiatric side effects of biological response modifiers (BRMs) have been documented in specific patient samples. Although these side effects likely have a predictable impact on patients quality of life (QOL), no instrument currently measures the cumulative effect of the various complaints patients' report. The current study investigated the reliability and validity of the Functional Assessment of Cancer Treatment-Biological Response Modifier (FACT-BRM) scale for measuring QOL in a sample of melanoma patients receiving interferon. Measures of distress, depression, and fatigue were also obtained using standardized, well-validated instruments. Results indicate increased symptom burden, depression, and fatigue, and decreased quality of life over 4 months of IFN therapy. The FACT-BRM demonstrated good psychometrics and sensitivity to change, and thus appears to be a good instrument for measuring QOL in patients receiving BRMs.

Symptom clusters in advanced illness.

OBJECTIVES: To review the four sets of symptom clusters commonly seen in patients with advanced illness, and their definitions, associated symptomatology, and management. DATA SOURCES: Research and review articles and textbooks. CONCLUSION: Symptoms of patients with advanced illness tend to occur not isolation, but in symptom clusters. The ability to cluster symptoms in both assessment and management reduces the use of polypharmacy, systemic toxicities, and improves the patient's quality of life. IMPLICATIONS FOR NURSING PRACTICE: It is important that the nurse providing symptom management for the oncology patient understand the importance of clustering certain symptoms together.

Combined-modality therapy with gemcitabine and radiotherapy as a bladder preservation strategy: results of a phase I trial.

PURPOSE: We conducted a phase I trial of gemcitabine given twice weekly with concurrent radiotherapy in patients with muscle-invasive bladder cancer. PATIENTS AND METHODS: Eligible patients underwent maximal transurethral resection of their bladder tumors followed by twice-weekly infusion of gemcitabine with 2 Gy/d concurrent radiotherapy to the bladder, for a total of 60 Gy over 6 weeks. The starting dose of gemcitabine was 10 mg/m(2) with subsequent dose levels of 20, 27, 30, and 33 mg/m(2). The primary end point was the determination of the maximum-tolerated dose (MTD) of twice weekly gemcitabine with concurrent radiotherapy. Secondary end points included assessment of toxicity associated with combined-modality therapy and initial assessment of the rate of bladder preservation. RESULTS: Twenty-four patients were enrolled and 23 were assessable for toxicity and response. No significant toxicity was demonstrated at the 10 or 20 mg/m(2) twice-weekly doses. Dose-limiting toxicity (DLT) occurred in two of three patients treated at 33 mg/m(2). Intermediate dose levels of 27 and 30 mg/m(2) were then evaluated. The MTD of gemcitabine was 27 mg/m(2). The DLT was systemic, manifested as an elevation in liver function tests, malaise, and edema. Fifteen of 23 patients (65%) are alive with bladders intact and no evidence of recurrent disease at a median follow-up of 43 months. CONCLUSION: Twice-weekly gemcitabine with concurrent radiotherapy at 2 Gy/d to a total dose of 60 Gy is well-tolerated. The MTD of gemcitabine is 27 mg/m(2). There is a high rate of bladder preservation in this selected group of patients.

Longitudinal course of depression, fatigue, and quality of life in patients with high risk melanoma receiving adjuvant interferon.

PURPOSE: Treatment of malignant melanoma with interferon-alpha has been associated with a variety of side effects ranging from fatigue to depression, and a concomitant impact on quality of life (QOL), in a variety of case reports and cross-sectional clinical trials. Few, if any, studies have been conducted with the express purpose of assessing the longitudinal course of depression, fatigue, and QOL before and during interferon therapy. DESCRIPTION OF STUDY: The current study reports on 16 patients who were assessed at 6 points in time: baseline, post high dose, and 1, 2, 3, and 6 months post high dose treatment with interferon-alpha with the Brief Symptom Inventory, Beck Depression Inventory, Revised Piper Fatigue Scale, and Functional Assessment of Cancer Therapy-Biological Response Modifiers. RESULTS: Results revealed consistent changes from baseline through 6 month assessment. Specifically, increased somatic complaints, depression, and fatigue were observed on the BSI, BDI, and RPFS, respectively. Additional reductions in QOL on the FACT-BRM were also identified. CLINICAL IMPLICATIONS: The findings suggest that IFN has a significant effect on QOL, but that it may be the somatic symptoms of fatigue that contribute to changes on measures of mood. Limiting the amount of fatigue and depression would appear to be significant if individuals are to successfully complete IFN therapy.

Phase II trial of oral cyclophosphamide, prednisone, and diethylstilbestrol for androgen-independent prostate carcinoma.

BACKGROUND: The authors evaluated the combination of oral cyclophosphamide, oral prednisone, and diethylstilbestrol (DES) in patients with androgen-independent prostate carcinoma (AIPC). METHODS: Thirty-seven patients with prostate carcinoma refractory to androgen ablation who had undergone antiandrogen withdrawal (if previously treated with an antiandrogen) were enrolled in the current study. They were treated with oral cyclophosphamide 100 mg per day on Days 1-20, prednisone 10 mg per day continuously, and DES 1 mg continuously, on a 30-day cycle. Warfarin 1 mg per day was given as prophylaxis for thrombosis. Patient levels of prostate-specific antigen (PSA) were monitored on a monthly basis, with imaging studies every 3 months. Patients continued to receive therapy until disease progression or the occurrence of significant toxicity. The effect of therapy on the patient's quality of life was assessed using the Functional Assessment of Cancer Therapy-Prostate. RESULTS: Thirty-six patients were evaluable for response. Of the 36 patients, 15 (42%) had a 50% or greater decline in PSA levels from pretreatment levels and 1 patient (6%) with measurable disease had a partial response to therapy. The median duration of response was 4.5 months (range, 4-18 months). The overall median survival period was 16.4 months. The treatment was well tolerated, with only three patients removed from the study for toxicities associated with treatment. One patient, who had been treated for more than 24 months, developed acute leukemia. Quality of life evaluation in 17 patients showed a significant improvement in responders, whereas nonresponders had no deterioration while receiving therapy. CONCLUSIONS: Cyclophosphamide, prednisone, and DES represent a well tolerated, low-cost combination therapy with significant activity in the treatment of patients with AIPC.

Phase II trial of paclitaxel, estramustine, etoposide, and carboplatin in the treatment of patients with hormone-refractory prostate carcinoma.

BACKGROUND: Preclinical data suggest that the combination of intravenous (i.v.) paclitaxel, carboplatin, oral etoposide, and oral estramustine (TEEC) has significant activity in patients with advanced, hormone-refractory prostate carcinoma. The authors conducted this clinical trial to evaluate the addition of carboplatin to the three-drug combination of paclitaxel, estramustine, and etoposide (TEE). METHODS: Twenty patients with carcinoma of the prostate that was progressing despite hormone therapy were enrolled on this Phase II trial. Patients were treated with oral estramustine, 280 mg three times daily, and oral etoposide, 50 mg/m2, once daily on Days 1-7, with i.v. paclitaxel, 135 mg/m2, over 1 hour followed by carboplatin (area under the curve, 5) on Day 2 of each 21-day treatment cycle. Patients were evaluated for response after three cycles, and three additional cycles were given to responding or stable patients. RESULTS: Nineteen patients were evaluable for response, and 12 patients had measurable disease at baseline. The measurable response rate was 58% (7 of 12 patients; 95% confidence interval [95% CI], 28-85%), and all of those were partial responses. Eleven patients had decreases >50% from their baseline prostate specific antigen levels during therapy, for a response rate of 58% (95% CI, 34-80%) by this criterion. The median time to disease progression was 5.5 months, with a median survival of 14.2 months. Major toxicities included Grade (according to version 2 of the National Cancer Institute Common Toxicity Criteria) 4 neutropenia in 4 patients, Grade 4 thrombocytopenia in 4 patients, and anemia > or = Grade 3 in 4 patients. One patient had a deep vein thrombosis. CONCLUSIONS: The combination of TEEC was active in patients with hormone-refractory prostate carcinoma. The regimen was tolerable, with primarily hematologic toxicity. The addition of carboplatin to TEE did not appear to add to the efficacy of the three-drug combination of antimicrotubule agents.

Placental metastasis of maternal melanoma.

Metastasis of maternal malignant tumor to the products of conception is a rare event. Melanoma is the most common maternal malignant tumor to metastasize to the placenta and the fetus. We report the case of a 28-year-old woman with melanoma during pregnancy. At parturition, histologic evaluation of the placenta revealed metastatic melanoma, and multiple organ metastasis developed. The infant was free of disease. Metastasis to products of conception portends a poor prognosis for the mother. To our knowledge, this report is the first of a patient with melanoma metastasis to the placenta to survive more than 7 months after parturition. As caretakers of patients with melanoma, dermatologists are in a position to coordinate and direct the care and follow-up treatment of affected patients.

Phase II trial of tetrathiomolybdate in patients with advanced kidney cancer.

PURPOSE: Tetrathiomolybdate (TM), a copper-lowering agent, has been shown in preclinical murine tumor models to be antiangiogenic. We evaluated the antitumor activity of TM in patients with advanced kidney cancer in a Phase II trial. EXPERIMENTAL DESIGN: Fifteen patients with advanced kidney cancer were eligible to participate in this trial. TM was initiated p.o. at 40 mg three times a day with meals and 60 mg at bedtime to deplete copper. A target serum ceruloplasmin (CP) level of 5-15 mg/dl was defined as copper depletion. Doses of TM were reduced for grade 3-4 toxicity and to maintain a CP level in the target range. Once copper depletion was attained, patients underwent baseline tumor measurements and then again every 12 weeks for response assessment. Patients not exhibiting progressive disease at 12 weeks after copper depletion continued on treatment. Serum levels of Interleukin (IL)-6, IL-8, vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) were assayed pretreatment and at various time points on treatment. Dynamic contrast enhanced-magnetic resonance imaging (DCE-MRI) was performed on selected patients in an attempt to assess changes in tumor vascularity. RESULTS: All of the patients rapidly became copper depleted. Thirteen patients were evaluable for response. No patient had a complete response or PR. Four patients (31%) had stable disease for at least 6 months during copper depletion (median, 34.5 weeks). TM was well tolerated, with dose reductions most commonly occurring for grade 3-4 granulocytopenia of short duration not associated with febrile episodes. Serum levels of IL-6, IL-8, VEGF, and bFGF did not correlate with clinical activity. Serial DCE-MRI was performed only in four patients, and a decrease in vascularity seemed to correlate with necrosis of a tumor mass associated with tumor growth. CONCLUSIONS: TM is well tolerated and consistently depletes copper as measured by the serum CP level. Clinical activity was limited to stable disease for a median of 34.5 weeks in this Phase II trial in patients with advanced kidney cancer. Serum levels of proangiogenic factors IL-6, IL-8, VEGF, and bFGF may correlate with copper depletion but not with disease stability in this small cohort. TM may have a role in the treatment of kidney cancer in combination with other antiangiogenic therapies.

Strengthening end-of-life care through specialty nursing certification.

The purpose of this study was to determine the adequacy of content related to end-of-life (EOL) care in materials used in the nursing certification process across clinical nursing specialties. Thirty-eight certification examination blueprints, 18 specialty nursing scope and standards of practice documents, and 28 specialty nursing core curriculum text books were analyzed by using descriptive statistics to determine the quantity and quality of content related to nine critical areas of EOL content contained in them. Fifteen (38 per cent) of the certification examination blueprints contained at least one of the critical EOL content areas. Eight (44 per cent) of the scope and standards of practice documents contained at least one sentence on EOL care. Seven (25 per cent) of the 28 textbooks contained at least one chapter dedicated to EOL care content, and 129.5 (0.8 per cent) of the 15,706 textbook pages reviewed were dedicated to EOL care content. Expert ratings regarding the overall accuracy, currency, and comprehensiveness of EOL content found in the textbooks were poor to good. An increased focus on EOL care in the nursing specialty certification process is warranted. The content of nursing specialty certification examinations has a direct influence on nursing education as well as a significant impact on nursing practice in clinical specialty areas.
