RESUMO

BACKGROUND: In pediatric intensive care units (PICUs), parents and healthcare professionals attend to children who verbally and non-verbally express their pain and suffering, fears, anxieties, desires, and wishes in complex intensive care situations. What can we learn from these experiences to improve the way we can take care of and support children? OBJECTIVES: The main objective of this clinical ethics study was to focus on the experience stories of parents during their child's hospitalization in a PICU, to analyze their discourse, and to propose an ethical perspective. METHOD: The current research collects the experience reports of parents during their child's hospitalization in a PICU and those of the caregivers who treated them. A total of 17 semi-directive interviews were conducted in the PICU of the Nantes University Hospital from November 2017 to June 2019. Each interview lasted around 1 h. The main results of our study are analyzed and informed by the four ethical principles of T. Beauchamp and J. Childress: autonomy, beneficence, non-maleficence, and justice. RESULTS: The interviews highlighted the difficulties encountered by parents during the hospitalization of their children, such as the distance between their home and the hospital, the technicality of PICU environment, and the difficulty in finding their place as parents. For medical and paramedical teams, their main concerns are undoubtedly to improve the coherence and continuity of their stand toward parents, to promote parental autonomy, and to remain fully aware of the profound existential changes that the child's illness brings about for parents: It is the caregivers' duty to take this into account and to respect the parents' rhythm as much as possible. CONCLUSIONS: The main disagreements between healthcare teams and parents, where they exist, are communication problems that are easily controlled, for the most part, by caregivers.

RESUMO

The injection of hematoporphyrin derivative (5 mg/kg i.v.) followed 24 hr later by a neodymium-yttrium aluminium garnet laser irradiation shows the destruction of CX1 tumors grafted on nude mice. This acidophilic necrosis occurred with a significantly increased frequency in tumors treated by hematoporphyrin derivative injection and irradiated with the neodymium-yttrium aluminium garnet laser as compared with noninjected but irradiated tumors or with injected tumors irradiated with sunlight. On the basis of our data, it seems difficult to maintain the hypothesis of singlet oxygen production as the only mechanism of the phenomenon. Further studies will be necessary to explain the necrosis that we observed.

RESUMO

PURPOSE: A randomized trial was conducted in patients with small-cell lung cancer (SCLC) to determine if survival can be improved by a weekly chemotherapy regimen combining various drugs. PATIENTS AND METHODS: Two hundred twenty-three patients were randomized to receive either six courses of a multiple-drug combination (MDC) regimen (Adriamycin [ADR; doxorubicin; Farmitalia Carlo Erba, Milan, Italy] 25 mg/m2 intravenously [i.v.] on day 1; etoposide [VP16] 120 mg/m2 i.v. on day 1; cyclophosphamide [CPA] 500 mg/m2 i.v. on day 1; cisplatin 60 mg/m2 i.v. on day 8; vindesine [VDS] 3 mg/m2 i.v. on day 8; vincristine [VCR] 2 mg i.v. on day 15; methotrexate [MTX] 100 mg/m2 i.v. on day 15), or a standard chemotherapy (SC) regimen (ADR 50 mg/m2 i.v. on day 1; CPA 1 g/m2 i.v. on day 1; VP16 80 mg/m2 i.v. on days 1 to 3). RESULTS: In 98 MDC-treated and 101 SC-treated assessable patients, we observed 69% and 62% objective responses rates, respectively. There was no significant difference in survival, with median durations and 2-year overall survival rates of 49 and 43 weeks and 8.5% and 7.9%, respectively. There was a significant increase in response rate in favor of MDC patients with limited disease (84% v 62%). Toxicity was tolerable, although SC was more hematotoxic, with 76% (v 59%) experiencing leukopenia and 17% (v 7%) experiencing thrombocytopenia (grades III and IV). If the cumulative doses received were nearly equal to the scheduled cumulative doses in both arms, the total relative dose-intensity (RDI) was significantly higher in the SC arm. The difference was due to increased treatment delays in the MDC arm. CONCLUSION: Weekly MDC failed to improve survival rates in patients with SCLC.

RESUMO

The European Organization for Research and Treatment of Cancer (EORTC) Lung Cancer Working Party conducted a randomized trial comparing cisplatin (CDDP; 120 mg/m2, day 1) and carboplatin (CBDCA; 325 mg/m2, day 1) in combination with etoposide (VP16; 100 mg/m2, days 1, 2, and 3) in advanced non-small-cell lung cancer (NSCLC). Two hundred twenty-eight patients were eligible for survival and 202 assessable for response. We obtained 27 of 100 objective responses (ORs; 27%) in the CDDP arm and 16 of 102 (16%) in the CBDCA arm (P = .07). There was no significant difference in survival. Toxicity, consisting mainly of myelosuppression and renal function impairment, was significantly increased in the patients receiving the CDDP treatment. We conclude that CDDP plus VP16 was more active but also more toxic than CBDCA plus VP16 in advanced NSCLC.

RESUMO

We conducted a randomized study comparing the survival after treatment with cisplatin (120 mg/m2) or cisplatin plus etoposide (100 mg/m2 on days 1, 2, and 3) in 162 evaluable patients with advanced non-small-cell lung cancer (NSCLC). No statistically significant difference in survival was detected; the median survival was 26 and 22 weeks, respectively, for patients receiving cisplatin and for those receiving cisplatin plus etoposide. The objective response rate was 19% for cisplatin and 26% for the combination; the corresponding response rates were 17% and 43% in patients with limited disease. No significant differences were detected between the two study arms as far as toxicity was concerned, except for alopecia and granulocytopenia, which occurred more frequently in patients treated with cisplatin plus etoposide.

RESUMO

PURPOSE: This study attempted to determine the prognostic value for survival of various pretreatment characteristics in patients with nonresectable non-small-cell lung cancer in the context of more than 10 years of experience of a European Cooperative Group. PATIENTS AND METHODS: We included in the analysis all eligible patients (N = 1,052) with advanced non-small-cell lung cancer registered onto one of seven trials conducted by the European Lung Cancer Working Party (ELCWP) during one decade. The patients were treated by chemotherapy regimens based on platinum derivatives. We prospectively collected 23 variables and analyzed them by univariate and multivariate methods. RESULTS: The global estimated median survival time was 29 weeks, with a 95% confidence interval of 27 to 30 weeks. After univariate analysis, we applied two multivariate statistical techniques. In a Cox regression model, the selected explanatory variables were disease extent, Karnofsky performance status, WBC and neutrophil counts, metastatic involvement of skin, serum calcium level, age, and sex. These results were confirmed by application of recursive partitioning and amalgamation algorithms (RECPAM), which led to classification of the patients into four homogeneous subgroups. CONCLUSION: We confirmed by our analysis the role of well-known independent prognostic factors for survival, but also identified the effect of the neutrophil count, rarely studied, with the use of two methods: a classical Cox regression model and a RECPAM analysis. The classification of patients into the four subgroups we obtained needs to be validated in other series.

RESUMO

PURPOSE: A phase II randomized trial was conducted in patients with advanced non-small-cell lung cancer (NSCLC) to determine if the combination of moderate-dose cisplatin and carboplatin was active (primary end point) and could avoid the long-term limiting (renal, auditive, neurologic) toxicity of high-dose cisplatin, which prevents prolonged administration (secondary end point). PATIENTS AND METHODS: One hundred twenty-one patients, registered between April 1990 and September 1991, were randomized to receive high-dose cisplatin (120 mg/m2 intravenously [IV] on day 1) or a combination of moderate-dose carboplatin (200 mg/m2 IV on day 1 and moderate-dose cisplatin (30 mg/m2 IV on days 2 and 3). One hundred nine patients were eligible: 56 in the cisplatin arm and 53 in the combined arm; 52 and 47, respectively, were assessable for response. All had stage IV disease (or stage IIIB with pleural effusion) and none had received prior chemotherapy. RESULTS: There was a 23% objective response rate to cisplatin (23% of the eligible patients) and a 22% response rate to cisplatin plus carboplatin (21% of the eligible patients). The overall survival rate was not significantly different between the two study arms, but responders in the combined arm survived significantly longer than those in the high-dose cisplatin arm (respective median survival durations, 66 and 30 weeks). Although there was no difference between the arms for alopecia, emesis, and leukopenia, the combined arm was significantly associated with more thrombocytopenia (although rarely severe) and, more importantly, with less renal (19% v 36%), auditive (4% v 16%), and neurologic (0% v 16%) toxicity of any grade. CONCLUSION: The regimen combining moderate-dose cisplatin and carboplatin was active against advanced NSCLC and significantly less toxic than high-dose cisplatin.

RESUMO

The study set out to determine the rate of long-term survivors (LTS) in patients treated with platinum-containing chemotherapy for advanced non-small cell lung cancer (NSCLC), to identify prognostic factors predicting long-term survival (> or = 2 years) and to report the LTS natural history. Eligible patients with advanced NSCLC treated by chemotherapy in one of seven trials conducted by the European Lung Cancer Working Party from December 1980 to August 1991 were included. All patients received cisplatin and/or carboplatin. Of these, 1052 patients were eligible and 24 variables were analysed as potential prognostic factors. Actuarial 2-year and 5-year survival rates were, respectively, 7.4 and 1.8%. All patients surviving for > or = 5 years had limited disease and were treated by complementary chest irradiation and/or surgery. Univariate prognostic factor analysis for LTS identified as significant no major weight loss, limited disease, no liver metastases, normal white blood cells and neutrophils and normal lactic dehydrogenase levels. By multivariate analysis, the only significant factor was limited disease. Objective response to chemotherapy was also found to be, as disease extent, a highly significant predictor for LTS. Thus, the two best prognostic factors for LTS were non-metastatic disease and response to chemotherapy.

RESUMO

The aim of this study was the assessment of the predictive value for survival of an antitumoral response to three courses of chemotherapy in association with various pretreatment characteristics in patients with non-resectable non-small cell lung cancer treated by cisplatin- (or carboplatin)-based combination regimens. Patients considered for this study were eligible patients with advanced non-small cell lung cancer registered in one of the seven trials conducted by the European Lung Cancer Working Party from December 1980 to August 1991. All these trials tested chemotherapy regimens with platinum derivatives (cisplatin and/or carboplatin). In this population of 1052 eligible patients, 752 were assessed in this analysis. Data were prospectively collected on 23 pretherapeutic variables and objective response after three chemotherapy cycles. The predictive value of response to chemotherapy on survival (measured from the time of response assessment i.e. 12 weeks after registration in the trial) was studied by univariate analysis as well as by multivariate methods (adjustment of the impact of several covariates simultaneously on the dependent variable) with adjustment for the pretreatment prognostic variables. After three cycles of chemotherapy, the global estimated median survival time was 24 weeks with a 95% confidence interval of 22-25 weeks. By univariate analysis, we identified an objective response to chemotherapy as a highly significant discriminant marker (P < 0.0001) for further survival with estimated median survival times of 41 weeks (95% CI: 38-46) and 19 weeks (95% CI: 17-20), respectively, for the responding and non-responding patients. In a Cox regression model fitted to the data using a forward stepwise procedure, this variable was the first selected explanatory variable. Its effect was adjusted by the introduction in the model of initial disease extent, Karnofsky performance status, serum calcium level and white blood cell count. These results were consistent with those obtained by application of recursive partitioning and amalgamation algorithms (RECPAM) which led to a classification of the patients into three homogeneous subgroups. Our results, using a classical Cox regression model consistent with those highlighted by application of a RECPAM analysis, found an objective response to chemotherapy to be a predominant predictive factor for further survival, although it did not allow any conclusion about a causal relationship. The RECPAM results led to a classification of the patients into three subgroups which needs to be validated in other series.

RESUMO

Sixty-six patients with advanced non-small cell lung cancer have been entered into a phase I/II study of a combination of gemcitabine and cisplatin. An initial phase I portion of the study has been completed, and 16 patients have been entered using a fixed dose of gemcitabine 1,000 mg/m2 as a 30-minute intravenous infusion weekly for 3 weeks. Cisplatin was administered on day 15 following gemcitabine with appropriate prehydration and posthydration. The study was designed to allow for sequential groups of three patients to receive three dose levels of cisplatin (60 mg/m2, 75 mg/ m2, and 100 mg/m2). Dose modification and patient numbers were to be increased at any dose level if significant toxicity was observed. The regimen was well tolerated at all doses, and the final level of cisplatin 100 mg/m2 was expanded to 10 patients before the phase II portion was opened. Neutropenia (World Health Organization grade 4 in three patients) and thrombocytopenia (grade 3 or 4 in five patients) were the main hematologic toxicities recorded. These episodes were brief and uncomplicated. Grade 3 nausea and vomiting occurred in 12 patients, but was no worse than would be expected from cisplatin alone. Alopecia, when it occurred, was minimal (no hair loss in 10 patients and grade 1 or 2 in six patients). No significant renal toxicity or neurotoxicity was seen. A phase II study with cisplatin 100 mg/m2 and gemcitabine 1,000 mg/m2 has been opened, and to date 43 patients are evaluable for response. Eighteen (42%) patients have achieved partial remissions. The study will close when 50 evaluable patients have been entered.

RESUMO

A randomized study with cisplatin (120 mg/m2) or carboplatin (325 mg/m2) plus etoposide (100 mg/m2, days 1 to 3) in 162 evaluable patients with advanced non-small cell lung cancer (NSCLC) compared response and survival after treatment. No statistically significant difference in survival rates was detected; median survival was 25 weeks for patients receiving cisplatin and 24 weeks for those receiving carboplatin. The objective response rate was 25% for cisplatin plus etoposide and 20% for carboplatin plus etoposide. Granulocytopenia, diarrhea, and nephrotoxicity were significantly more frequent with cisplatin plus etoposide than with carboplatin plus etoposide. Severe nausea and/or vomiting occurred during 59 of 77 courses (77%) with cisplatin and 48 of 75 (64%) with carboplatin (P = .13). Unlike cisplatin plus etoposide, carboplatin plus etoposide was administered on an outpatient basis. At the dose used in the present study, carboplatin plus etoposide was as effective as but less toxic than cisplatin plus etoposide for NSCLC and could be given more easily.

RESUMO

The existence of large shipyards accounts for the particular frequency of pleural mesothelioma in the Nantes-St. Nazaire region of France. From 1955 to 1985, 167 cases were diagnosed. Occupational exposure to asbestos was involved in 131 cases (88 percent). There was a great predominance of epithelial types (135) over mixed (25) and fibrosarcomatous (7) types. Survival, estimated by the actuarial method, was 54 percent at one year from first symptoms and 39 percent from histologic diagnosis. No subject was alive four years after diagnosis. Histologic type and asbestos exposure had no predictive value in our series. Survival was longer in patients under 60 years of age and when mesothelioma originated on the left side. Overall, treated patients had significantly longer survival than untreated patients. However, there was no significant difference in survival with respect to the type of treatment given: surgery, chemotherapy, talc poudrage or their combination.

RESUMO

The purpose of this study was to determine the activity of a 4-drug combination chemotherapy: cisplatin, mitomycin C, vindesine and 5-fluorouracil (5-FU) in patients with advanced non-small cell lung cancer (NSCLC). Chemotherapy consisted of the administration of cisplatin (30 mg/m2 d 1-4), mitomycin C (10 mg/m2 d 1), vindesine (3 mg/m2 d 1) and 5-FU (1 g/m2 d 1-4 by continuous intravenous infusion). In patients older than 70 years, and in those who received prior irradiation or chemotherapy, cisplatin and 5-FU were omitted on day 4. Courses were repeated every 4 weeks and evaluation of response was performed after the first 2 courses. In case of response, treatment was continued until best response or untolerable toxicity. Among 182 eligible patients, 75% had received no prior therapy; 41% had locoregional disease and 59% metastatic disease; 41% lost more than 5% of their pretherapy body weight. A 34% objective response rate was observed in the 164 evaluable patients (31% in all the eligible patients) including 4 complete and 52 partial responses. Patients with locoregional disease had a significantly better response rate than those with metastases (44% vs 27%). The overall median survival was 26 weeks. Significant hematological toxicity was documented but the most serious adverse event was the occurrence of 18 (10%) cardiac or sudden deaths. These toxic deaths were significantly associated with a 5% loss of body weight prior to therapy. The addition of 5-FU to combination of cisplatin, mitomycin C and vindesine does not improve antitumoral effect but results in very significant cardiac toxicity.

RESUMO

The purpose of this study was to evaluate the efficacy and safety of docetaxel as first- and second-line chemotherapy for advanced non-small cell lung cancer (NSCLC) under routine clinical conditions. Two hundred and three patients with advanced NSCLC received docetaxel 100 mg/m2 (1-h intravenous infusion) every 3 weeks, with oral corticosteroid pre-medication, of whom 173 were eligible. Median age was 60 (29-78) years and median Karnofsky performance status was 80% (60-100). A total of 77% of patients had metastatic disease, 33% had bone metastases and 18% had liver metastases. The treatment was second-line or more for 72 patients (35%). Overall response rates in the eligible population were 19.7% [95% CI, 12.5-23.0] for both treatments, 22.6% for first-line treatment and 13.8% for second-line treatment. Median survival was 8.3 months and 1-year survival was 35% for the overall population (8.7 months and 38%, respectively, for patients receiving first-line treatment and 7.2 months and 27%, respectively, for patients receiving second-line treatment). Neutropenia, grade 3 and 4, occurred in 57% of the cycles and 5% of patients experienced febrile neutropenia. Alopecia (62% of patients), neuro-sensory symptoms (32%), asthenia (28%), diarrhea (22%), nausea (22%) and nail disorders (20%) were the most common non-hematological adverse effects. A total of 33% of patients suffered fluid retention, despite the use of corticosteroid pre-medication, but this was only severe in 1.5% of patients. It was possible to confirm the efficacy of docetaxel as a single agent for first- and second-line chemotherapy in a large patient population treated in a community setting.

RESUMO

PURPOSE: To identify pretreatment variables predicting response to platinum derivatives containing chemotherapy in patients with unresectable non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Eligible patients included in one of the 7 consecutive clinical trials conducted by the European Lung Cancer Working Party between December 1980 and August 1991. All patients received a cisplatin or carboplatin containing chemotherapy. We analyzed 22 potential prognostic factors including sex, age, histology, performance status, weight loss, type of lesions, extent of disease, main metastatic sites and several biological parameters, namely white blood cell count (WBC), neutrophil count, platelet count, hemoglobinemia, creatininemia, serum alkaline phosphatases and LDH. RESULTS: On 1052 eligible patients. 107 were not assessable for response. The objective response rate was 26% (95% C.I.: 23, 29%). Univariate analysis identified as statistically significantly associated with a higher objective antitumoral response rate the following characteristics: a normal platelet count, the absence of skin metastasis, the absence of adrenal metastasis, a higher creatininemia, a normal hemoglobinemia, an older age and a normal WBC count. On a restricted set of variables including data from 777 patients, a multivariate logistic regression model disclosed age and platelet count as significantly and independently related to response rate. CONCLUSION: Clinical and demographic characteristics of patients with unresectable NSCLC, as well as routine laboratory parameters, could not accurately predict response to chemotherapy in a population of patients selected for a clinical trial. Future studies on this subject should include more sophisticated variables as new biomolecular makers.

RESUMO

We studied the pharmacomodulating effects of a marine substance, bistramide D, which is capable of inducing terminal differentiation on the expression of the c-erb-B1, ras, src, myc and p53 genes in the NSCLC-N6 cell line established from a non-small cell lung carcinoma. Analysis (subsequent to treatment) demonstrated that among the genes for which it was possible to detect expression, namely c-erb-B1, c-myc and p53, only the expression of the p53 gene varied significantly. The increase of the expression rate of the p53 gene underlines its prominent role in the control of cell proliferation and differentiation.

RESUMO

The correlation between the degree of expression of the multidrug resistance-1 (MDR-1) gene and the process of differentiation into non-small-cell, bronchopulmonary carcinoma was studied in vitro and in vivo. For this purpose, a technique for the quantitative analysis of MDR-1 gene expression was developed by competitive reverse-transcriptase polymerase chain reaction. The study of 9 epidermoid carcinomas with various degrees of differentiation did not enable us to establish a correlation in vivo in the patient. However, an in vitro study performed on a non-small-cell lung carcinoma cell line and two of its clones showed that MDR-1 gene expression increased with the degree of differentiation, which was confirmed in vivo when this line was xenografted into nude mice.

RESUMO

Non-small-cell lung carcinoma (NSCLC) is a particularly serious disease because of its chemoresistance to current treatments. To investigate the nature of his generally innate resistance, we cloned an established cell line (NSCLC-N6) derived from a non-small cell bronchopulmonary carcinoma. Four cell subpopulations (C15, C65, C92 and C98) were isolated from the mother line. These four clones were studied in comparison with each other for cell doubling time in vitro, ploidy, chemosensitivity in vitro, cytogenetic, expression of the oncogene erb-B2 and other tumor markers (Kr, CEA and Chr A). Each clone shows a distinct biologic pattern for various biological parameters. Our results indicated hat cell doubling time (in vitro) increased when the hyperploid population was prevailing. The clones differ in their chemosensitivity to therapeutic agents. This cellular diversity might help to explain why these tumors are chemoresistant. This heterogeneity within NSCLC tumors should be taken into consideration in the choice of treatment.

RESUMO

Navelbine (vinorelbine, NVB) is the first semisynthetic 5'-nor-vinca-alkaloid selected for clinical trial. NVB has been shown to have a good level of activity against different experimental solid tumors in animals, with low neurotoxicity. In the phase II study, 78 patients with an inoperable non-small-cell lung cancer (NSCLC) were treated with NVB at a weekly dose of 30 mg/m2. No patient had previously received chemotherapy. Twenty-three of the 78 eligible patients showed a partial response (29.4% with a 95% confidence limits: 19.5-39.5). Eight patients were not evaluable and the percentage of partial response were 32.8% in the evaluable patients group. The median response duration was 34 weeks, and the median survival time for the overall population reached 33 weeks. Grade 3-4 leukopenia was seen in 12.5% of cycles. No thrombocytopenia occurred. At the dosage schedule used, NVB seems a very promising agent in the treatment of NSCLC.

RESUMO

We initiated prospective study testing efficacy of multidrug chemotherapy (cisplatin, ifosfamide, mitomycin) with irradiation in brain metastases of non small cell lung cancer at first diagnosis. Among 22 patients we obtained ten objective local responses (45%). Median survival was 7 months. Toxicity was mild (> 2 - OMS): hematologic = five patients; gastrointestinal = one patient. Among 11 patients who received chemotherapy before radiotherapy we had seven objective responses (patients evaluated after three courses of chemotherapy and before radiotherapy). This result indicates the interest of this protocol of chemotherapy in brain metastases. The association of this protocol of chemotherapy and radiotherapy appears effective, well tolerated and few toxic.
