Randomized study of paclitaxel-cisplatin versus cisplatin-teniposide in patients with advanced non-small-cell lung cancer. The European Organization for Research and Treatment of Cancer Lung Cancer Cooperative Group

PURPOSE: To compare two cisplatin based chemotherapy schedules in patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: A total of 332 patients with advanced NSCLC were randomized to receive cisplatin 80 mg/m2 on day 1 either in combination with teniposide 100 mg/m2 on days 1, 3, and 5 (arm A) or paclitaxel 175 mg/m2 by 3-hour infusion on day 1 (arm B); cycles were repeated every 3 weeks. RESULTS: Fifteen patients were ineligible; patient characteristics were well balanced between the two arms: 71% were male, 71% had less than 5% weight loss, 89% had a World Health Organization (WHO) performance status of 0 to 1, 51% had adenocarcinoma, and 61% had stage IV disease. Hematologic toxicity was significantly more severe in arm A (leukopenia, neutropenia, and thrombocytopenia grade 3 or 4: 66% v 19%, 83% v 55%, 36% v 2% in arms A and B, respectively), which resulted in more febrile neutropenia (27% v 3% in arms A and B, respectively), dose reductions, and treatment delays. There were a total of nine toxic deaths, six due to neutropenic sepsis: five in arm A and one in arm B. In contrast, arthralgia/myalgia (grade 2 or 3, 4% v 17%), peripheral neurotoxicity (grade 2 or 3, 6% v 29%), and hypersensitivity reactions (1% v 7%, all grades) were significantly more frequent in arm B. The frequency and severity of other toxicities were comparable between the two arms. Responses were one complete and 44 partial on arm A (28%) and two complete and 61 partial (41%) on arm B (P = .018). There was no significant difference in survival, with median and 1-year survivals 9.9 versus 9.7 months and 41% versus 43%, respectively in arm A and B. Progression-free survival was 4.9 and 5.4 months in arm A and B, respectively. Selected centers participated in a quality-of-life (QoL) assessment, which was performed by the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and LC-13 administered at baseline and every 6 weeks thereafter. Arm B achieved a better score at week 6 for emotional, cognitive and social functioning, global health status, fatigue, and appetite loss, which was lost at 12 weeks. In conclusion, arm B appears superior to arm A with regard to response rate, side effects, and QoL. CONCLUSION: Although survival was not improved, arm B offers a better palliation for advanced NSCLC patients than arm A.     

Influence of sun exposures during childhood and during adulthood on melanoma risk. EPIMEL and EORTC Melanoma Cooperative Group. European Organisation for Research and Treatment of Cancer

Sun exposure in both childhood and adult life represents the main environmental risk determinant for cutaneous melanoma. However, little is known about the joint effects of sun exposure during early and later life on melanoma risk. A case-control study in Belgium, Germany and France conducted in 1991-1992 suggests that the melanoma risks attached to indicators related to sun exposure appear to combine their effects in an additive way. We therefore constructed composite indices of sun exposure during childhood and during adulthood, assuming additive combinations of melanoma risk associated with each indicator of sun exposure. Logistic regression modeling showed that the melanoma risk associated with a given level of sun exposure during adulthood increased with higher sun exposure during childhood, but the increase in risk was higher than the simple addition of melanoma risk associated with sun exposure during childhood or adulthood. In turn, high sun exposure during childhood constituted a significant risk factor for melanoma only if there was substantial sun exposure during adult life. We thus suggest that sun exposure during childhood and during adulthood would be interdependent as far as their impact on melanoma risk is concerned. Our results support the hypothesis by which the important contribution of sun exposure during childhood in melanoma occurrence is not properly assessed by retrospective epidemiologic studies. Sun avoidance during childhood would have a greater impact on melanoma risk than sun avoidance during adulthood.     

Clinical significance of minimal residual disease in childhood acute lymphoblastic leukemia. European Organization for Research and Treatment of Cancer--Childhood Leukemia Cooperative Group

Osteoclasts (OCL) resorb bone. They are essential for the development of normal bones and the repair of impaired bones. The function of OCL is presumed to be supported by cytokines and other biological mediators, including tumor necrosis factor (TNF)-alpha and nitric oxide (NO). Bacterial lipopolysaccharide (LPS) is a potent inducer of TNF-alpha and inducible nitric oxide synthase (iNOS), which is the specific enzyme for synthesizing NO from L-arginine. To obtain direct evidence on LPS-induced TNF-alpha production and iNOS expression by OCL, OCL-enriched cultures were prepared by 7-day cocultures of bone marrow cells of adult BALB/c mice and osteoblastic cells (OBs) derived from calvaria of newborn BALB/c mice, and the generation of TNF-alpha and iNOS in OCL stimulated with LPS was examined immunocytochemically. When the cultured cells were stimulated with 100 ng/ml of LPS, OCL clearly showed TNF-alpha and iNOS expression. Without LPS-stimulation, no expression was observed. TNF activity in the culture supernatants of the OCL-enriched cultures in the presence of LPS was also detected by cytotoxic assay that used TNF-sensitive L929 cells. The dentin resorption activity of OCL was estimated by area and number of pits formed on dentin slices, which were covered by the OCL fraction and cultured in the presence or absence of LPS, sodium nitroprusside (SNP; a NO generating compound), N(G)-monomethyl L-arginine acetate (L-NMMA; a competitive inhibitor of NO synthase (NOS)), or LPS plus L-NMMA. Pit formation was obviously inhibited in the presence of SNP and slightly inhibited in the presence of L-NMMA, but it was not affected in the presence of LPS or LPS plus L-NMMA. These findings indicate that OCL produces TNF and expresses iNOS in response to LPS, but the LPS-activation of OCL scarcely affects pit formation by them.

Rehabilitation following anterior cruciate ligament (ACL) reconstruction is varied. Patients are usually prescribed an independent home exercise program, although some patients may attend physical therapy for additional supervised exercise. It is not known whether additional supervised exercise provides any further benefit. The purpose of this study was to compare efficacy for two types of rehabilitation following ACL reconstruction. A randomized controlled trial of 31 ACL-reconstructed patients was used to test the hypothesis that a home program plus supervised rehabilitation (Group S) is more effective than a home program (Group H) alone. Function, activity level, anterior tibial translation, and muscle strength were measured preoperatively and at 3 and 6 months postoperatively. Improvement of function, activity level, muscle strength, and anterior tibial translation was evident in both groups, but no significant differences were found between groups even though the sample size was sufficient to detect small treatment effects. It was concluded that supervised exercise, in addition to a home program, has minimal extra benefit for patients who have undergone ACL reconstruction.     

Randomized trial of alternating versus sequential radiotherapy/chemotherapy in limited-disease patients with small-cell lung cancer: a European Organization for Research and Treatment of Cancer Lung Cancer Cooperative Group Study

PURPOSE: To evaluate the effectiveness of alternating or sequential schedules of cyclophosphamide, doxorubicin, and etoposide (CDE) chemotherapy and irradiation in patients with previously untreated small-cell lung cancer (SCLC). MATERIALS AND METHODS: A total of 335 eligible patients were randomized between five courses of CDE chemotherapy followed by thoracic irradiation 50 Gy in 20 daily fractions (S) and the same total dose of chemotherapy and irradiation split into four courses of five daily fractions delivered on days 14 to 21 of the second and subsequent chemotherapy courses (A). Patients had a median age of 61 years (range, 33 to 75); 224 (66%) were male; the Eastern Cooperative Oncology Group (ECOG) performance status (PS) was 0 or 1 in 311; and 254 had weight loss less than 10%. RESULTS: The overall median survival duration was 15 months, with 62% (95% confidence interval [CI], 57% to 67%) 1-year, 25% (95% CI, 20% to 30%) 2-year, and 14% (95% CI, 10% to 18%) 3-year survival rates. There was no significant difference between the arms. The median survival time was 14 months in A and 15 months in S. One-year survival was 60% in A (95% CI, 53% to 67%) and 64% in S (95% CI, 57% to 71%); 2-year survival was 26% in A (95% CI, 19% to 33%) and 23% in S (95% CI, 16% to 30%); and 3-year survival was 12% in A (95% CI, 6% to 18%) and 15% in S (95% CI, 9% to 21%). World Health Organization (WHO) grade 3 and 4 neutropenia occurred in 90% of A and 77% of S patients (P < .001) and WHO grade 3 and 4 thrombocytopenia in 33% of A and 20% of S patients (P < .001). Rates of other acute and late toxicities were similar in both arms. Hematologic toxicity compromised treatment dose delivery; less than 50% of A patients received greater than 95% of prescribed chemotherapy and 77% their full radiation course, compared with 60% and 93% for arm S (P < .009). Local relapse was the site of first failure in 60% of all patients and 75% of these suffered an in-field relapse; no difference could be seen between the two arms. CONCLUSION: This trial failed to confirm the superiority of an alternating schedule of delivery. For this combination of chemotherapy and irradiation, hematologic toxicity compromised treatment delivery and could have contributed to the overall result. The poor rates of local control are disappointing and require intensification of the radiation therapy strategy.     

Intraocular pressure in an unselected sample of 6- to 7-year-old Chinese children

Intraocular pressure (IOP) was measured in one-hundred-twenty-three 6- to 7-year-old Chinese children. Children who had at least one myopic parent had higher IOP's than children with two nonmyopic parents. There was a trend for myopic children to have higher IOP's than nonmyopic children.     

Adjuvant portal-vein infusion of fluorouracil and heparin in colorectal cancer: a randomised trial. European Organisation for Research and Treatment of Cancer Gastrointestinal Tract Cancer Cooperative Group, the Gruppo Interdisciplinare Valutazione Interventi in Oncologia, and the Japanese Foundation for Cancer Research

BACKGROUND: There is conflicting evidence on the efficacy of regional adjuvant chemotherapy, via portal-vein infusion (PVI), after resection of colorectal cancer. We undertook a randomised controlled multicentre trial to investigate the efficacy of PVI (500 mg/m2 fluorouracil plus 5000 IU heparin daily for 7 days). METHODS: 1235 of about 1500 potentially eligible patients were randomly assigned surgery plus PVI or surgery alone (control). The patients were followed up for a median of 63 months, with yearly screening for recurrent disease. The primary endpoint was survival; analyses were by intention to treat. FINDINGS: 619 patients in the control group and 616 in the PVI group met eligibility criteria. 164 (26%) control-group patients and 173 (28%) PVI-group patients died. 5-year survival did not differ significantly between the groups (73 vs 72%; 95% Cl for difference -6 to 4). The control and PVI groups were also similar in terms of disease-free survival at 5 years (67 vs 65%) and the number of patients with liver metastases (79 vs 77%). INTERPRETATION: PVI of fluorouracil, at a dose of 500 mg/m2 for 7 days, cannot be recommended as the sole adjuvant treatment for high-risk colorectal cancer after complete surgical excision. However, these results cannot eliminate a small benefit when PVI is used at a higher dosage or in combination with mitomycin.

Posterior laryngeal clefts (PLCs) are described in the literature as rare laryngeal abnormalities. The authors believe type I clefts are much more common than previously reported. In two busy pediatric tertiary care centers, such clefts are the second most common congenital laryngeal finding at rigid endoscopy, second only to laryngomalacia. PLCs frequently present with symptomatology that can be attributed to other common disease processes and are often undiagnosed unless the surgeon maintains a high index of suspicion and specifically examines the posterior glottis by palpation during microlaryngoscopy. This report presents a series of 41 patients with type I PLCs, reviews their subtle and often confusing presenting signs and symptoms, and describes a simple yet reliable method of diagnosis.     

Emotionality, emotion regulation, and adaptation among 5- to 8-year-old children.

This study investigated relations between emotionality, emotion regulation, and children's behavioral adaptation in a longitudinal design. Mothers rated emotionality and emotion regulation related to anger, fear, and positive emotions-exuberance for 151 children at age 5 and later at age 6 years 6 months. Emotionality and emotion regulation measures were modestly related. Preschool ratings at age 6 (n=125), maternal ratings at age 6 years 6 months (n=133), and elementary school ratings at age 8 (n=135) of problems and competence were also collected. High anger emotionality and low regulation of positive emotions and exuberance predicted externalizing problem behavior and prosocial behavior. High fear emotionality and low fear regulation predicted internalizing problem behavior. There were few interactive effects of emotionality and regulation.

Cognitive behavioral therapy for 4- to 7-year-old children with anxiety disorders: A randomized clinical trial.

Objective: To examine the efficacy of a developmentally appropriate parent–child cognitive behavioral therapy (CBT) protocol for anxiety disorders in children ages 4–7 years. Method: Design: Randomized wait-list controlled trial. Conduct: Sixty-four children (53% female, mean age 5.4 years, 80% European American) with anxiety disorders were randomized to a parent–child CBT intervention (n = 34) or a 6-month wait-list condition (n = 30). Children were assessed by interviewers blind to treatment assignment, using structured diagnostic interviews with parents, laboratory assessments of behavioral inhibition, and parent questionnaires. Analysis: Chi-square analyses of outcome rates and linear and ordinal regression of repeated measures, examining time by intervention interactions. Results: The response rate (much or very much improved on the Clinical Global Impression Scale for Anxiety) among 57 completers was 69% versus 32% (CBT vs. controls), p     

The influence of HLA-matched sibling donor availability on treatment outcome for patients with AML: an analysis of the AML 8A study of the EORTC Leukaemia Cooperative Group and GIMEMA. European Organization for Research and Treatment of Cancer. Gruppo Italiano Malattie Ematologiche Maligne dell'Adulto

To determine whether patients with a HLA-identical sibling donor have a better outcome than patients without a donor, an analysis on the basis of intention-to-treat principles was performed within the framework of the EORTC-GIMEMA randomized phase III AML 8A trial. Patients in complete remission (CR) received one intensive consolidation course. Patients with a histocompatible sibling donor were then allocated allogeneic bone marrow transplantation (alloBMT), the patients without a donor were randomized between autologous BMT (ABMT) and a second intensive consolidation (IC2). 831 patients <46 years old and alive >8 weeks from diagnosis were included. HLA typing was performed in 672 patients. AlloBMT was performed during CR1 in 180 (61%) out of 295 patients with a donor. Another 38 patients were allografted: five in resistant disease, 14 during relapse and 19 in CR2. ABMT was performed in 130 (34%) out of 377 patients without a donor in CR1, in six (2%) patients during relapse and in 38 (10%) patients during CR2. The disease-free survival (DFS) from CR for patients with a donor was significantly longer than for patients without a donor (46% v 33% at 6 years; P=0.01, RR 0.78, 95% confidence interval 0.63-0.96). The overall survival from diagnosis for patients with a donor was longer, but not statistically significant, than for patients without a donor (48% v 40% at 6 years; logrank P=0.24). When patients were stratified according to prognostic risk groups, the same trend in favour of patients with a donor was seen for survival duration and the DFS remained significantly longer for this group of patients.     

A cross-validation of the European Organization for Research and Treatment of Cancer QLQ-C30 (EORTC QLQ-C30) for Japanese with lung cancer

The EORTC QLQ-C30 was developed in English-speaking cultures. To determine if this instrument could cross a broad cultural divide and be used in Japan, the cross-cultural validity of its Japanese version was estimated. In evaluating psychometric testing, internal consistency by Cronbach's alpha, item-discrimination by multitrait scaling analysis, and validity analysis with ECOG performance score (PS) and Karnofsky Performance Status Scale (KPS) were performed. The QLQ-C30 (version 1.0) was given to 105 patients with lung cancer. Although the response rate was low in patients with PS 4, the questionnaire was well accepted by patients with PS 0-3. The Japanese QLQ-C30 has a weak scale of role functioning in terms of item discriminative validity. It also has a weak scale of cognitive functioning in items of discriminative validity and internal consistency. However, known-groups comparison showed the expected clinical validity with PS for all the scales except for financial impact, and longitudinally clinical validity with KPS was shown in scales of cognitive functioning, fatigue, and nausea and vomiting. Multitrait scaling analysis showed that the predicted scales constituting quality of life (QOL) in the English-speaking culture were extracted from the Japanese QLQ-C30, and found to be valid in Japan, indicating its possible usefulness as an instrument that is universally applicable across cultures.     

Evaluation of confluence model variables on IQ and achievement test scores in a sample of 6- to 11-year-old children.

The confluence model, proposed by R. B. Zajonc and G. B. Markus (see record 1975-09290-001) as a psychosocial model of cognitive development, was tested on a nationally representative cross-sectional sample of 7,060 male and female children born during a period of high and increasing birth rate. Family size, sibling order within family sizes, and hypothesized age-dependent effects were tested. Scores on subtests of the WISC and the Wide Range Achievement Test served as dependent variables. Findings indicate an inverse relationship between family size and the dependent measures, whereas other confluence variables failed to account for a significant proportion of the variance in test scores. Age-dependent effects were also nonsignificant. Obtaining support for family size effects in the absence of other effects predicted by confluence is viewed as a failure to support the model. The need for theoretical refinements of confluence variables is discussed. (20 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Food choices of 4 to 6-year-old overweight and nonoverweight children while role-playing as adults.

The following study compared the food choices made by overweight and non-overweight preschoolers while role-playing a mother who bought food for a family, and examined the influence of maternal restriction on food choice. After screening 619 children for height and weight, 56 overweight children (equal sex distribution, ages 4-6) and 56 non-overweight children (matched on age, sex, demographics) were selected to participate. Children's purchases of low and high caloric snacks, drinks, and dinner products in a miniature supermarket were recorded. Mother and child-reported maternal restriction were assessed using the Child Feeding Questionnaire (CFQ) and the Kid's CFQ. Compared to non-overweight children, overweight children choose more high-calorie foods when role-playing a mother. Maternal restriction did not differ between overweight and non-overweight children. Both children's and mothers' reported maternal restriction were unrelated to food choices and there were no significant interactions between restriction and weight status on food choices. In conclusion, while parental restriction seems to be unrelated to children's food choices, family food patterns might have great impact already at young ages.

Corticosteroids significantly delay the onset of docetaxel-induced fluid retention: final results of a randomized study of the European Organization for Research and Treatment of Cancer Investigational Drug Branch for Breast Cancer

PURPOSE: To confirm the efficacy of docetaxel in patients with breast cancer previously treated with one chemotherapy regimen for advanced or metastatic disease and to compare the incidence of fluid retention (FR) and skin toxicity when docetaxel is administered with and without prophylactic corticosteroids. PATIENTS AND METHODS: Eighty-three patients, pretreated with one chemotherapy regimen for metastatic breast cancer (MBC) with bidimensionally measurable and progressive disease, were eligible for this randomized trial. Docetaxel with prophylactic oral antihistamine was administered at a dose of 50 mg/m2 as a 1-hour infusion on days 1 and 8 every 21 days and patients were randomized to receive methylprednisolone (40 mg days -1, 0, 1, 7, 8, and 9 of each cycle) (arm A) or no methylprednisolone (arm B). RESULTS: Twenty-eight patients (34%, 95% confidence interval [CI], 23% to 45%) achieved on objective response. The median time to disease progression and median overall survival time were 5 and 13.5 months, respectively. In total, 415 cycles of docetaxel were administered (arm A: N = 219, median = six; arm B: N = 196, median = five). The most common toxicity observed was grade 3 or 4 neutropenia, which occurred in 79% of patients. Clinically significant nonhematologic side effects included skin reactions and asthenia. In an intent-to-treat analysis, patients who received methylprednisolone premedication had a delayed onset of FR (median time to onset of FR: arm A, 84 days; arm B, 62 days; P = .01) and received a higher median cumulative dose of docetaxel before the onset of FR (arm A, 333 mg/m2; arm B, 215 mg/m2; P = .001). There was no statistically significant difference in the incidence of skin toxicity between the two arms. CONCLUSION: Docetaxel, at this dose and schedule, has definite antitumor activity in pretreated MBC patients. Moreover, this is the first randomized trial to show that corticosteroids have a favorable impact on docetaxel-induced FR.     

Broad ability factors in 12- to 13-year-old children, the theory of fluid and crystallized intelligence, and the differentiation hypothesis.

Carried out a simple-structure factor analysis of test data from a sample of 149 6th graders in Norway. Broad factors were interpreted to represent Visualization, Speediness, and Fluency as well as Fluid and Crystallized Intelligence. The results are discussed in relation to R. B. Cattell"s (1971) and J. L. Horn"s (1968) theories of intelligence. Relating the findings to an earlier study of Norwegian 10–11 yr old 4th graders, some of the complexities and inconsistencies that characterize the evidence for and against the differentiation hypothesis are discussed.
