Vemurafenib-induced bilateral facial palsy.

The United States Food and Drug Administration (FDA) approved Vemurafenib in August 2011, for treatment of melanoma with BRAF V600 mutation. It has shown improvement in the median overall survival of melanoma patients. The most common adverse effects of vermurafenib are arthralgia, rash, alopecia, photosensitivity and fatigue. Other infrequent and severe adverse reactions reported in patients include keratocanthomas, hypersensitivity, Stevens Johnson Syndrome, toxic epidermal necrolysis, uveitis, QT prolongation, and hepatotoxicity. We hereby present a case of bilateral facial palsy as an adverse effect of vemurafenib therapy, seen after six weeks of commencement of the drug. Complete resolution of the symptoms was seen when the patient was taken off vemurafenib.

Celiac crisis in a patient with chronic lymphocytic leukemia and hypogammaglobulinemia.

Celiac crisis is an acute, fulminant form of celiac disease manifesting with severe diarrhea, metabolic and electrolyte abnormalities, and weight loss. It is mostly seen in children, and there are very few reports in adults. We present a 67-year-old patient with chronic lymphocytic leukemia (CLL) who presented with weight loss of 40 pounds, severe diarrhea, hypoalbuminemia and hypokalemia. The patient was immunosuppressed with hypogammaglobulinemia, which is common in CLL. Thus, the patient had negative serological studies for celiac disease. An endoscopic evaluation and HLA typing supported the diagnosis of celiac disease. Although the differential diagnosis was broad, exclusion of other etiologies for diarrhea, prompt diagnosis of celiac disease and initiation of gluten-free diet resolved the crisis. This is the first such report of a patient presenting with celiac crisis on a background of hypogammaglobulinemia.

Randomized phase III study of docetaxel compared with paclitaxel in metastatic breast cancer.

PURPOSE: This randomized, controlled, multicenter, open-label, phase III study compared docetaxel versus paclitaxel in patients with advanced breast cancer that had progressed after an anthracycline-containing chemotherapy regimen. PATIENTS AND METHODS: Patients (n = 449) were randomly assigned to receive either docetaxel 100 mg/m2 (n = 225) or paclitaxel 175 mg/m2 (n = 224) on day 1, every 21 days until tumor progression, unacceptable toxicity, or withdrawal of consent. RESULTS: In the intent-to-treat population, both the median overall survival (OS, 15.4 v 12.7 months; hazard ratio [HR], 1.41; 95% CI, 1.15 to 1.73; P = .03) and the median time to progression (TTP, 5.7 months v 3.6 months; HR, 1.64; 95% CI, 1.33 to 2.02; P < .0001) for docetaxel were significantly longer than for paclitaxel, and the overall response rate (ORR, 32% v 25%; P = .10) was higher for docetaxel. These results were confirmed by multivariate analyses. The incidence of treatment-related hematologic and nonhematologic toxicities was greater for docetaxel than for paclitaxel; however, quality-of-life scores were not statistically different between treatment groups over time. CONCLUSION: Docetaxel was superior to paclitaxel in terms of OS and TTP. ORR was higher for docetaxel. Hematologic and nonhematologic toxicities occurred more frequently in the docetaxel group. The global quality-of-life scores were similar for both agents over time.

Polymorphisms in glutathione S-transferases (GSTM1 and GSTT1) and survival after treatment for breast cancer.

The response to treatment for breast cancer is likely predicted by a number of disease and tumor tissue characteristics, many of which are under active investigation. One area that has received little attention is that of endogenous capabilities to respond to reactive oxygen species and subsequent byproducts resulting from radiation therapy and a number of chemotherapeutic agents, preventing cytotoxicity toward tumor cells. The glutathione S-transferases are key conjugating enzymes in this response, and GSTM1 and GSTT1 have deletion polymorphisms that result in no enzyme activity. In this retrospective study, we evaluated the role of GSTM1- and GSTT1-null genotypes on disease-free and overall survival among 251 women who received treatment for incident, primary breast cancer. Women were identified through Tumor Registry records and normal archived tissue retrieved for genotyping. Adjusting for age, race, and stage at diagnosis, women with null genotypes for GSTM1 and GSTT1 had reduced hazard of death [adjusted hazard ratio (HR), 0.59; 95% confidence interval (CI), 0.36-0.97; and HR, 0.51; CI, 0.29-0.90, respectively] in relation to those with alleles present. Furthermore, women who were null for both GSTM1 and GSTT1 had one-third the hazard of death of those with alleles for both genes present (adjusted HR, 0.28; 95% CI, 0.11-0.70). Similar relationships were noted for risk of recurrence. These data indicate that interindividual differences in activity of enzymes that prevent therapy-generated reactive oxidant damage may have an important impact on disease recurrence and overall survival.

Intrathecal cytotoxic T-cell immunotherapy for metastatic leptomeningeal melanoma.

A 49-year-old patient with primary, recurrent melanoma on the lower extremity developed metastatic leptomeningeal melanoma that did not respond to treatment with radiation therapy or intrathecal interleukin 2 (IL-2). Disease was characterized by neurological symptoms, including loss of hearing, loss of short-term memory, and gait disturbance. CD8+ CTLs were generated in vitro using autologous dendritic cells pulsed with peptides from the melanoma-associated antigens tyrosinase (145-156), Melan-A/MART-1 (26-35), and gp100/Pmel 17 (209-217). The CTLs exhibited up to 74% specific lysis against peptide-pulsed autologous EBV-transformed B cells, with Melan-A-specific CTLs yielding the greatest lytic activity. CD8+ CTLs possessed a type 1 cytokine profile, expressing tumor necrosis factor alpha and IFNgamma but not IL-4. Infusions of CTLs were supported with systemic low-dose IL-2 administration. 111In labeling and computerized gamma imaging were used to monitor the distribution of CTLs up to 48 h after infusion. Intra-arterial delivery via the right carotid artery was followed by redistribution of the CTLs to the lungs, liver, and spleen within 16 h. In contrast, delivery via an indwelling Ommaya reservoir resulted in prolonged retention of CTLs within the brain for at least 48 h after infusion. Marked but transient elevations in tumor necrosis factor alpha, IFN-gamma, and IL-6 in the cerebrospinal fluid were observed within 4 h of CTL infusion. There was no evidence of tumor progression throughout the treatment period, and clinically the patient showed some resolution of neurological symptoms.

Preoperative computed tomography scans for parotid tumor evaluation.

OBJECTIVE: We sought to determine whether an advantage is obtained in the routine use of computed tomography (CT) scans in preoperative assessments of parotid tumors. METHODS: A prospective study of 32 consecutive cases of patients who underwent evaluation for parotidectomies was performed. Twenty-nine received preoperative CT scans. The scans were systematically reviewed to see if they correlated with the clinical findings. Specifically, we compared clinical and CT assessments of tumor size, location, density, and malignancy. Further comparisons were performed based on postoperative tissue pathology. RESULTS: In our series of patients, routine preoperative CT scans resulted in the discovery of details not revealed on clinical examination: some masses were found to be extra-parotid rather than primary parotid tumors, some tumors deemed to be deep were superficial, tumor density was more clearly identified, and certain pathology correlates were clarified. Most importantly, there were instances of detection of additional tumors in the same lobe, and in one instance in the opposite lobe, that were not otherwise noticed. CONCLUSIONS: To reduce errors of omission in the treatment of suspected parotid tumors, it would seem appropriate to consider the inclusion of CT scans for the routine preoperative evaluation of all parotid masses.

Association between survival after treatment for breast cancer and glutathione S-transferase P1 Ile105Val polymorphism.

A glutathione S-transferase (GST) P1 polymorphism results in an amino acid substitution, Ile105Val; the Val-containing enzyme has reduced activity toward alkylating agents. Cancer patients with the variant enzyme may differ in removal of treatment agents and in outcomes of therapy. We evaluated survival according to GSTP1 genotype among women (n = 240) treated for breast cancer. Women with the low-activity Val/Val genotype had better survival. Compared with Ile/Ile, hazard ratios for overall survival were 0.8 (95% confidence interval, 0.5-1.3) for Ile/Val and 0.3 (95% confidence interval, 0.1-1.0) for Val/Val (P for trend = 0.04). Inherited metabolic variability may influence treatment outcomes.

Clinical and immune responses in advanced melanoma patients immunized with an anti-idiotype antibody mimicking disialoganglioside GD2.

PURPOSE: To determine immune responses and toxicity to the anti-idiotype vaccine, as well as clinical responses and survival, we initiated a clinical trial for patients with advanced melanoma treated with an anti-idiotype antibody (TriGem) that mimics the disialoganglioside GD2. PATIENTS AND METHODS: Forty-seven patients with advanced melanoma received either 1-, 2-, 4-, or 8-mg doses of TriGem (Titan Pharmaceuticals Inc, South San Francisco, CA) mixed with QS-21 adjuvant (Aquila Biopharmaceuticals, Inc, Worcester, MA) 100 microg subcutaneously weekly for 4 weeks and then monthly until disease progression. Median age was 57 years, there were 32 men and 15 women, 43% of patients had undergone prior therapy for metastatic disease, 55% had disease confined to soft tissue, and 45% had visceral metastasis. RESULTS: Hyperimmune sera from 40 of 47 patients showed an anti-anti-idiotype (Ab3) response. Patient Ab3 was truly Ab1' because it specifically bound purified disialoganglioside GD2. The isotypic specificity of the Ab3 antibody consisted of predominantly immunoglobulin (Ig)G, and all IgG subclasses were represented. One patient had a complete response that persisted at 24 months, and 12 patients were stable from 14+ to 37+ months (median, 18+ months). Disease progression occurred in 32 patients on study from 1 to 17 months (median, 5.5 months), and 21 have died at 1 to 16 months (median, 6 months). The Kaplan-Meier-derived overall median survival has not been reached. Median survival has not been reached for the 26 patients with soft tissue disease only and was 13 months for 21 patients with visceral metastasis. Toxicity consisted of local reaction at the site of injection and mild fever and chills. CONCLUSION: TriGem has minimal toxicity and generates robust and specific IgG immune responses against GD2. Objective responses were minimal, but there may be a favorable impact on disease progression and survival that will require prospective randomized trials.

Underrepresentation of patients 65 years of age or older in cancer-treatment trials.

BACKGROUND: Studies have documented the underrepresentation of women and blacks in clinical trials, and their recruitment is now federally mandated. However, little is known about the level of participation of elderly patients. We determined the rates of enrollment of patients 65 years of age or older in trials of treatment for cancer. METHODS: We analyzed data on 16,396 patients consecutively enrolled in 164 Southwest Oncology Group treatment trials between 1993 and 1996 according to sex, race (black or white), and age under 65 years or 65 or older. These rates were compared with the corresponding rates in the general population of patients with cancer, derived from the 1990 U.S. Census and from the National Cancer Institute's Surveillance, Epidemiology, and End Results Program for the period from 1992 through 1994. Fifteen types of cancer were included in the analysis. RESULTS: The overall proportions of women and blacks enrolled in Southwest Oncology Group trials were similar to or the same as the estimated proportions in the U.S. population of patients with cancer (women, 41 percent and 43 percent; blacks, 10 percent and 10 percent, respectively). In contrast, patients 65 years of age or older were underrepresented overall (25 percent vs. 63 percent, P<0.001) and in trials involving all 15 types of cancer except lymphoma. The underrepresentation was particularly notable in trials of treatment for breast cancer (9 percent vs. 49 percent, P<0.001). The findings were similar when data on patients who were 70 years of age or older were analyzed, when 15 trials that excluded older patients were eliminated from the analysis, and when community-based enrollment was analyzed separately from enrollment at academic centers. CONCLUSIONS: There is substantial underrepresentation of patients 65 years of age or older in studies of treatment for cancer. The reasons should be clarified, and policies adopted to correct this underrepresentation.

Intractable hypercalcemia due to a metastatic carcinoid secreting parathyroid hormone-related peptide and interleukin-6: response to octreotide.

We describe a patient with a malignant carcinoid tumor who presented with severe, intractable hypercalcemia that would not respond to conventional therapy with fluids and pamidronate. His plasma concentrations of parathyroid-hormone-related peptide (PTHrP) and interleukin-6 (IL-6) were elevated. The patient was treated with subcutaneous injections of octreotide with a good response, resulting in normocalcemia. Plasma PTHrP and IL-6 fell with the octreotide but remained elevated above the upper limit of normal. We conclude that although rare, hypercalcemia may be associated with carcinoid tumors and may be mediated through the secretion of cytokines and or PTHrP. Treatment with octreotide may be effective in treating hypercalcemia in such patients.

Phase II trial of biochemotherapy with interferon alpha, dacarbazine, cisplatin and tamoxifen in metastatic melanoma: a Southwest Oncology Group trial.

The therapeutic benefit of adding interferon alpha (IFNalpha) to established single-agent and combination chemotherapy regimens for the treatment of metastatic melanoma has not been proven. We designed the present study to estimate the response rate of IFNalpha, dacarbazine, cisplatin and tamoxifen in patients who had not been treated with systemic therapy for advanced disease. Using a schedule similar to that which had previously been shown to favor IFNalpha plus dacarbazine over dacarbazine alone, we treated patients with an "induction" regimen of IFNalpha, 15 mU m(-2) day(-1) intravenously 5 days/week for 3 weeks. Following induction, schedules of IFNalpha, 5 mU m(-2) day(-1) subcutaneously three times a week, and tamoxifen, 10 mg orally twice a day, were begun. Dacarbazine, 250 mg m(-2) day(-1) and cisplatin 33 mg m(-2) day(-1) for 3 consecutive days were repeated every 4 weeks, and subcutaneous IFNalpha and oral tamoxifen were continued until the discontinuation of chemotherapy. We treated 25 patients (18 men and 7 women, median age 52 years) and observed only 1 objective response (response rate 4%, 95% confidence interval 0.1%-20%). The toxicities of the regimen consisted of moderate myelosuppression and constitutional side-effects. On the basis of the low antitumor activity of this regimen, we do not recommend it for further study or for use as standard therapy of metastatic melanoma.

Antibody responses in melanoma patients immunized with an anti-idiotype antibody mimicking disialoganglioside GD2.

We initiated a clinical trial for patients with advanced malignant melanoma treated with an anti-idiotype antibody that mimics the disialoganglioside GD2. We report the clinical and immune responses of the first 12 patients entered into this trial. Patients received 1-, 2-, 4-, or 8-mg doses of the anti-idiotype antibody mixed with 100 microg of QS-21 adjuvant every other week, four times, and then monthly. Twelve patients have been on trial for 2-23 months, and all of them have generated immune responses. Patients were removed from the study if they demonstrated disease progression. Hyperimmune sera from all 12 patients revealed an anti-anti-idiotypic Ab3 response, as demonstrated by the inhibition of Ab2 binding to Ab1 by patients' immune sera. To further test the anti-anti-idiotypic response, patients' Ab3 antibodies were affinity purified on Sepharose 4B columns containing adsorbed immunizing anti-idiotype immunoglobulin. Purified Ab3 of all patients studied inhibited binding of Ab1 to a GD2-positive cell line. Purified Ab3 also inhibited binding of Ab1 to purified GD2, in a manner comparable to equal quantities of purified Ab1. The patient Ab3 was truly an Ab1' because it specifically bound to purified disialoganglioside GD2. The isotypic specificity of the Ab3 antibody was predominantly IgG, with only minimal IgM. The predominant IgG subclass was IgG1, with approximately equal quantities of IgG2, IgG3, and IgG4. These Ab3 antibodies reacted specifically with tumor cells expressing GD2 by immune flow cytometry and immunoperoxidase assays. Five patients' Ab3 antibodies studied for antibody-dependent cellular cytotoxicity were positive. One patient had a complete clinical response, with resolution of soft tissue disease, and six patients had stable disease, ranging from 9 to 23 months, and are being continued on vaccine therapy. Toxicity consisted of local reaction at the site of the injection, including induration and pain that generally resolved within a few days. Mild fever and chills were observed in 75% of the patients but rarely required acetaminophen. There was no additional toxicity, including abdominal pain that was previously seen with infusion of murine monoclonal anti-GD2 antibody. Current trials include patients with stage III melanoma and small cell lung cancer. Future trials will attempt to enhance the antitumor response by the addition of interleukin 2, granulocyte macrophage colony-stimulating factor, and other cytokines, together with the 1A7 vaccine.

Effect of glutamine on methotrexate efficacy and toxicity.

OBJECTIVE: To examine the effect of oral glutamine (GLN) on the efficacy and toxicity of methotrexate (MTX). SUMMARY BACKGROUND DATA: The use of high-dose chemotherapy regimens is limited by the severity of their toxicities. Oral GLN has been shown to decrease the gut toxicity seen with MTX treatment while enhancing its tumoricidal effect. METHODS AND RESULTS: Studies were done in laboratory rats and in breast cancer outpatients. Fischer 344 rats were randomized to 48 hours of prefeeding with GLN (1 g/kg/day) or an isonitrogenous amount of glycine. Rats were killed 24 hours after receiving a 20-mg/kg intraperitoneal dose of MTX. In the GLN group, there was a threefold increase in total MTX in the tumor as compared with the control group, and this increase was in both the diglutamated and pentaglutamated MTX. Inversely, there was a significant decrease in the total polyglutamated MTX in the gut in the GLN group. Given the results of this preclinical study, the authors performed a phase I trial. Nine patients diagnosed with inflammatory breast cancer received GLN (0.5 g/kg/day) during MTX neoadjuvant therapy, escalating from doses of 40 mg/m2 to 100 mg/m2 weekly for 3 weeks, followed by a doxorubicin-based regimen. No toxicity of oral GLN was detected. No patient showed any sign of chemotherapy-related toxicity. One patient had a grade I mucositis. Except for one, all patients responded to the chemotherapy regimen. Median survival was 35 months. CONCLUSIONS: These studies suggest that GLN supplementation is safe in its administration to the tumor-bearing host receiving MTX. By preferentially increasing tumor retention of MTX over that of normal host tissue, GLN may serve to increase the therapeutic window of this chemotherapeutic age.

Investigation of the mechanisms underlying the hypophagic effects of the 5-HT and noradrenaline reuptake inhibitor, sibutramine, in the rat.

1. Sibutramine is a novel 5-hydroxytryptamine (5-HT) and noradrenaline reuptake inhibitor (serotonin-noradrenaline reuptake inhibitor, SNRI) which is currently being developed as a treatment for obesity. Sibutramine has been shown to decrease food intake in the rat. In this study we have used a variety of monoamine receptor antagonists to examine the pharmacological mechanisms underlying sibutramine-induced hypophagia. 2. Individually-housed male Sprague-Dawley rats were maintained on reversed phase lighting with free access to food and water. Drugs were administered at 09 h 00 min and food intake was monitored over the following 8 h dark period. 3. Sibutramine (10 mg kg-1, p.o.) produced a significant decrease in food intake during the 8 h following drug administration. This hypophagic response was fully antagonized by the alpha 1-adrenoceptor antagonist, prazosin (0.3 and 1 mg kg-1, i.p.), and partially antagonized by the beta 1-adrenoceptor antagonist, metoprolol (3 and 10 mg kg-1, i.p.) and the 5-HT receptor antagonists, metergoline (non-selective; 0.3 mg kg-1, i.p.); ritanserin (5-HT2A/2C; 0.1 and 0.5 mg kg-1, i.p.) and SB200646 (5-HT2B/2C; 20 and 40 mg kg-1, p.o.). 4. By contrast, the alpha 2-adrenoceptor antagonist, RX821002 (0.3 and 1 mg kg-1, i.p.) and the beta 2-adrenoceptor antagonist, ICI 118,551 (3 and 10 mg kg-1, i.p.) did not reduce the decrease in food intake induced by sibutramine. 5. These results demonstrate that beta 1-adrenoceptors, 5-HT2A/2C-receptors and particularly alpha 1-adrenoceptors, are involved in the effects of sibutramine on food intake and are consistent with the hypothesis that sibutramine-induced hypophagia is related to its ability to inhibit the reuptake of both noradrenaline and 5-HT, with the subsequent activation of a variety of noradrenaline and 5-HT receptor systems.

Comparison of the effects of sibutramine and other monoamine reuptake inhibitors on food intake in the rat.

1. The effects of the potent 5-hydroxytryptamine (5-HT) and noradrenaline reuptake inhibitor (serotonin-noradrenaline reuptake inhibitor, SNRI), sibutramine, on the cumulative food intake of freely-feeding male Sprague-Dawley rats during an 8 h dark period were investigated and compared to those of the selective 5-HT reuptake inhibitor (selective serotonin reuptake inhibitor, SSRI), fluoxetine; the selective noradrenaline reuptake inhibitor, nisoxetine; the 5-HT and noradrenaline reuptake inhibitors, venlafaxine and duloxetine; and the 5-HT releaser and 5-HT reuptake inhibitor, (+)-fenfluramine. 2. Sibutramine (3 and 10 mg kg-1, p.o.) and (+)-fenfluramine (1 and 3 mg kg-1, p.o.) produced a significant, dose-dependent decrease in food intake over the 8 h dark period. These responses became apparent within the first 2 h following drug administration. 3. Fluoxetine (3, 10 and 30 mg kg-1, p.o.), and nisoxetine (3, 10 and 30 mg kg-1, p.o.) had no significant effect on food intake during the 8 h dark period. However, a combination of fluoxetine and nisoxetine (30 mg kg-1, p.o., of each) significantly decreased food intake 2 and 8 h after drug administration. 4. Venlafaxine (100 and 300 mg kg-1, p.o.) and duloxetine (30 mg kg-1, p.o.) also significantly decreased food intake in the 2 and 8 h following drug administration. 5. The results of this study demonstrate that inhibition of 5-HT and noradrenaline reuptake by sibutramine, venlafaxine, duloxetine, or by a combination of fluoxetine and nisoxetine, markedly reduces food intake in freely-feeding rats and suggest that this may be a novel approach for the treatment of obesity.

Influence of patient characteristics, socioeconomic factors, geography, and systemic risk on the use of breast-sparing treatment in women enrolled in adjuvant breast cancer studies: an analysis of two intergroup trials.

PURPOSE: To investigate the frequency of breast-sparing treatment among breast cancer patients subsequently enrolled in national cooperative group studies of adjuvant chemotherapy. PATIENTS AND METHODS: A data base was formed of 5,172 patients randomized onto two intergroup trials. Lumpectomy rates were analyzed within study-defined risk strata and across geographic regions. Significant predictors of lower lumpectomy usage were determined in multivariate analyses with variables that described patient and disease characteristics, systemic risk strata, geographic region, and socioeconomic indicators based on zip code of residence. RESULTS: Breast-conservation rates were 30% in the node-negative and 15% in the node-positive trials, with a wide geographic variation within each study (range, 14% to 49% and 9% to 31%, respectively). Lumpectomy use declined with increasing tumor size and did not exceed 40% even for tumors < or = 1 cm with negative nodes. With increasing risk of systemic relapse, frequency of lumpectomy declined (rates for five strata in order of increasing systemic risk: 41%, 33%, 24%, 18%, and 11%), even though these strata were not known at the time of the surgical decision. A logistic model confirmed the joint significance of geographic region and systemic risk. An exploratory model that adjusted for all important variables identified the following significant predictors of lower lumpectomy use: positive nodes; many positive nodes, increased systemic risk; tumor size > or = 2.0 cm; older age; South, Central or non-New England regions; and either lack of college degree or lower income levels. CONCLUSION: Breast-sparing therapy was used in the minority of women subsequently accrued to two national adjuvant breast cancer studies, even though this cohort and their referring surgeons represented a select population. Although multiple concrete factors were independent predictors of lower lumpectomy rates, prospective research is needed into how patients and their physicians approach the mastectomy versus lumpectomy decision.

Evaluation of multimodality treatment of locoregional esophageal carcinoma by Southwest Oncology Group 9060.

BACKGROUND: Continuous infusion 5-fluorouracil (CI5-FU) has been utilized concurrently with radiotherapy to improve tumor control. In this pilot trial, cisplatin, CI5FU, and radiotherapy were utilized for the treatment of locoregional esophageal carcinoma. It was postulated that the combination would be well tolerated and associated with high response rate and survival duration. METHODS: Thirty-two eligible patients with locoregional squamous cell carcinoma and adenocarcinoma of the esophagus received a regimen consisting of the following: radiotherapy, 50 Gray (Gy) (30 Gy anteroposterior/posteroanterior regional with 20 Gy AP/LPO/RPO boost) over 5 weeks, with CI5-FU 250 mg/m2/d for the duration of radiotherapy and cisplatin 25 mg/m2/day on Days 1-3 during Weeks 1 and 4 of the radiotherapy cycle. Upon completion of radiotherapy, two additional course, of cisplatin 75 mg/m2 on Days 1 and 29 and CI5-FU 300 mg/m2/day on Days 1-21 and 29-50 were delivered. Following imaging and endoscopic reassessment, patients with no evidence of disease received more chemotherapy. Surgery was suggested only for patients with residual local disease. RESULTS: Complete response was demonstrated in 44% of patients, clinically in 12 patients, and during surgery in 2 others. The median survival was 20 months, and the 1-year survival rate was 59%. Toxicity was severe, comprised of esophagitis, infection, and gastrointestinal complications. Dose delays and reductions occurred in the majority of patients. Four early deaths were noted. CONCLUSIONS: The regimen that was the focus of this trial has been active in the treatment of esophageal carcinoma. However, compared with existing regimens, its complexity and toxicity preclude its future use without modifications.
