Outbreaks of contaminated broncho-alveolar lavage related to intrinsically defective bronchoscopes.

From 5 March 2001 to 19 October 2001, outbreaks of broncho-alveolar lavage (BAL) contamination with Enterobacteraceae were detected in our 700-bed institution. We report the investigation of these outbreaks. A case was defined as the occurrence of pairs of specific Enterobacteraceae in BAL specimens among any patients who underwent bronchoscopy in the respiratory unit during the period of the outbreak. Contamination was identified in 117 BAL samples during three outbreaks among 418 patients, and was associated with bronchoscopes 11 and 12 (P<0.001). The other five devices in use were not linked with the outbreaks. During the first outbreak, particular pairs of micro-organisms were associated with a specific bronchoscope (Klebsiella pneumoniae/Proteus vulgaris with bronchoscope 11, and Morganella morganii/Proteus mirabilis with bronchoscope 12). Cultures of sputa from two patients also yielded M. morganii some days after bronchoscopic examination. Isolates from contaminated BAL samples and bronchoscope 11 had similar patterns by pulsed-field gel electrophoresis. No further cases occurred after removal of the implicated bronchoscopes. No deficiencies in disinfection procedures were detected and the source of contamination was found to be a loose port of the biopsy channel of the bronchoscope. Our findings underscore the urgent need to test bronchoscopic samples regularly and to improve the design and structure of bronchoscopes.

Docetaxel and concurrent radiotherapy after two cycles of induction chemotherapy with cisplatin and vinorelbine in patients with locally advanced non-small-cell lung cancer. A phase II trial conducted by the Groupe Francais de Pneumo-Cancerologie (GFPC).

CONTEXT: The most satisfactory treatment for patients with locally advanced non-small-cell lung cancer (NSCLC) is combination chemotherapy-radiotherapy (CT-RT). The optimal treatment modalities remain to be determined. OBJECTIVE: We conducted a multicenter phase II trial of the docetaxel-radiotherapy combination after induction chemotherapy with cisplatin-vinorelbine. The main endpoint was the objective response rate. PATIENTS AND METHODS: Patient with inoperable stage locally advanced NSCLC received induction chemotherapy consisting of two cycles of cisplatin 100 mg/m2 on D1 and vinorelbine 25 mg/m2 on D1, D8, D15 and D22. Patients with responses or stable disease then received concurrent RT-CT consisting of 25 mg/m2/week docetaxel and single-fraction radiotherapy (66 grays (Gy) in 33 fractions) over 6.5 weeks. RESULTS: Fifty-six patients were enrolled from 1 July 2000 to 31 December 2001. Sixteen patients left the trial after induction chemotherapy, eight for progression, five for toxicity, and two for intercurrent events. One patient underwent surgery after induction chemotherapy. In total, 40 of the 56 patients received RT-CT. Twelve (30%) of these 40 patients experienced grade III or IV pulmonary or esophageal toxicity. In the intention-to-treat analysis, the objective response rate was 46.4% (95% CI 33.0-60.2). The median time to progression was 6.2 months [1.1-26.0]. The median survival time was 13 months [0.3-44.9 months]. Nine patients progressed during RT-CT, six with brain metastases. CONCLUSION: Weekly docetaxel with concurrent radiotherapy, following chemotherapy is acceptable. The tumor response rate is moderate. Further trials are required to determine the risk-benefit relationship of this treatment schedule, and the possible benefit of adding other cytotoxic drugs.

[Chemotherapy for metastatic non-small cell lung cancer].

Treatment of stage IV non-small cell lung cancer (NSCLC) is based upon chemotherapy, with several meta-analyses showing an improvement of survival compared to supportive care alone. For first-line chemotherapy, the development of new third generation drugs (vinorelbine, gemcitabine, paclitaxel, docétaxel) with a better therapeutic index has led to the definition of 4 to 6 cycles of a platinum-based dual agent regime as standard therapy for performance stage (PS) 0-1 patients, producing a 1-year survival in the region of 35%. The choice of agents is based upon the differences in the toxicity profile of platinum-based combinations and on patient co-morbidities. For frail patients (PS>2 and elderly patients), single-agent chemotherapy seems more appropriate than cisplatin-based combinations; carboplatin or non-platinum combinations might be more effective. Third generation cytotoxic agents have modestly improved survival for patients with stage IV NSCLC but should probably provide an increased number of long-term survivors.

[The role of meta-analysis in assessing the treatment of advanced non-small cell lung cancer].

Meta-analysis is a statistical method allowing an evaluation of the direction and quantitative importance of a treatment effect observed in randomized trials which have tested the treatment but have not provided a definitive conclusion. In the present review, we discuss the methodology and the contribution of meta-analyses to the treatment of advanced-stage or metastatic non-small-cell lung cancer. In this area of cancerology, meta-analyses have provided determining information demonstrating the impact of chemotherapy on patient survival. They have also helped define a two-drug regimen based on cisplatin as the gold standard treatment for patients with a satisfactory general status. Recently, the meta-analysis method was used to measure the influence of gemcitabin in combination with platinium salts and demonstrated a small but significant benefit in survival, confirming that gemcitabin remains the gold standard treatment in combination with cisplatin.

[First-line treatment of metastatic non-small cell lung cancers].

The first-line treatment of non-small cell bronchial cancers at the metastatic stage relies on chemotherapy, the impact of which, in terms of survival in comparison with palliative care alone, has been confirmed by several meta-analyses. The recent development of new drugs (vinorelbine, gemcitabine, paclitaxel, docetaxel) that benefit from an improved efficacy-toxicity ratio, has led to the individualisation, as treatment standard in patients in a general state of good health, of bitherapies based on the combination of a platinum salt and recent active drugs. The latter exhibit similar efficacy, in terms of response and survival, providing PS 0 or 1 patients with a median survival of around 8 months and, at 1 year, nearing 35%. The choice of the first-line therapy in a given patient will be based essentially on the differences in toxicity profiles among the therapeutic regimens, taking into account the frequent co-morbidities in this population, the modalities of administration and the perspectives of second-line therapy. The patients with an altered general state of health (PS 2) will benefit from adapted treatment based on active monotherapy or bitherapy without cisplatin. The prolongation of the first-line therapy over and above 4 cycles following maximal reduction of the tumour does not provide enhanced survival and considerably increases toxicity. The recent cytotoxic agents appear to provide a real progress, although modest in the treatment of metastatic NSCBC, progress which is visible considering the proportion of patients still living in the long term.

Phase II randomized multicenter study evaluating a treatment regimen alternating docetaxel and cisplatin-vinorelbine with a cisplatin-vinorelbine control group in patients with stage IV non-small-cell lung cancer: GFPC 97.01 study.

BACKGROUND: The potential absence of cross-resistance between cisplatin and docetaxel in non-small-cell lung cancer (NSCLC) suggests that alternating regimens of cisplatin-based chemotherapy and docetaxel might increase the activity of chemotherapy in stage IV NSCLC. PATIENTS AND METHODS: Randomized, multicenter, non-comparative phase II study in patients with stage IV NSCLC (Eastern Cooperative Oncology Group performance status of 0-2). Patients randomized to alternating treatment group (A) received docetaxel 100 mg/m2 on days (D) 1 and 43 alternating with cisplatin 100 mg/m2 on D22 and vinorelbine 30 mg/m2 on D22, D29 and D36. Those randomized to the control group (B) received cisplatin 80 mg/m2 on D1, D22 and D43 and vinorelbine 30 mg/m2 once a week from D1 to D57. Treatment was continued for a further 6 weeks in the event of objective response or stabilization. RESULTS: Seventy patients were enrolled (group A: 38, group B: 32). More premature treatment discontinuations due to toxicity were observed in group A (median number of cycles: 3) than in group B (median number of cycles: 5). The intention-to-treat objective response rate was 10.8% [95% confidence interval (CI) 0.8% to 20.8%] in group A compared with 25% (95% CI 10% to 40%) in group B, the median time to treatment failure being 10.2 weeks and 17.3 weeks, respectively. The median survival and 1-year survival were 29.1 weeks and 39% in group A compared with 41.6 weeks and 42% in group B. Febrile neutropenia occurred in 5.9 and 4.9% of the cycles in group A and group B, respectively. Non-hematological toxicity was moderate in the two groups. CONCLUSIONS: The addition of docetaxel alternating with cisplatin-vinorelbine did not enhance the activity of this combination. The development of sequential regimens might be a more promising way of exploiting the absence of cross-resistance between these two drugs.

Results of a phase III study of early versus delayed whole brain radiotherapy with concurrent cisplatin and vinorelbine combination in inoperable brain metastasis of non-small-cell lung cancer: Groupe Français de Pneumo-Cancérologie (GFPC) Protocol 95-1.

PURPOSE: To determine if the timing of whole brain radiotherapy (WBRT) with respect to chemotherapy with cisplatin and vinorelbine would influence survival in patients with non-small-cell lung cancer (NSCLC) and concurrent brain metastasis. PATIENTS AND METHODS: One hundred seventy-six patients with brain metastasis from NSCLC were included in the study between July 1995 and October 1997. All patients received chemotherapy with cisplatin 100 mg/m2 on day 1 and vinorelbine 30 mg/m2 on days 1, 8, 15, 22. Cycles were repeated every four weeks. Evaluation of response was performed after two, four or six cycles. After two cycles, chemotherapy was administered to the responders to a maximum of six cycles. Patients were randomised to receive WBRT 30 Gy/10 fx/12 days and delayed corticosteroids. (arm A) for the intracranial nonresponders, or early on day 1 to 12 during the first cycle of chemotherapy (arm B). RESULTS: One hundred seventy-one patients were eligible: eighty-six in arm A and eighty-five in arm B; none had received prior chemotherapy; seventy-six and seventy-three, respectively, were assessable for response. There was a 21% overall objective response rate (OR) (with 1 complete response and 17 partial responses) after two cycles of chemotherapy alone (arm A) and a 20% OR (with 17 partial responses) to chemotherapy and early WBRT (arm B). The intracranial OR was 27% and 33%, respectively (P = 0.12). The six months survival rate (46% and 40%) and the median survival duration (24 and 21 weeks, respectively) were not significantly different between the two arms (P = 0.83, log-rank test). The major toxicity was severe or life-threatening neutropenia (grade 4), which occurred in 35% of arm A patients and 36% of arm B patients. There were thirteen treatment-related deaths (six in arm A and seven in arm B). There was no difference between the arms for haematological and neuro-toxicities. CONCLUSIONS: These results confirm the efficacy of chemotherapy in brain metastases of NSCLC and suggest that the timing (early or delayed) of WBRT did not influence survival of NSCLC with brain metastasis treated with concurrent chemotherapy.

[Efficacy of docetaxel in non-small cell lung cancer patients previously treated with platinum-containing chemotherapy. French Group of Pneumo-Cancerology].

PURPOSE: Determine the response to, and toxicity of docetaxel (Taxotere) in patients (pts) with inoperable non-small-cell lung cancer (NSCLC) previously treated with platinum-containing chemotherapy. PATIENTS AND METHODS: Twenty-seven patients with stage IIIB or IV NSCLC, having received one platinum-containing regimen were treated with 100 mg/m2/3 weeks of docetaxel until tumor progression or severe toxicity. Premedication with prednisolone and diosmin was given in all patients. Antitumoral activity was assessable in 21/27 pts. Median age: 52 years; WHO performance status 0-1: 77% pts, stage IV disease: 63% pts. RESULTS: 6/21 eligible pts (24%) achieved a partial response to treatment [C.I 95%: 5.6-42]. Median time to progression: 2.9 months, median survival: 8.5 months with a median follow-up of 23.7 months (range: 13.5-27). Hematologic toxicity: grade 3-4 neutropenia: 75% pts, febrile neutropenia: 11% cycles. Non hematologic toxicities: fluid retention, rash, alopecia, sensory neuropathy, asthenia, and nail changes. CONCLUSION: Docetaxel (Taxotere) administered at 100 mg/m2/3 weeks has relevant clinical activity against platinum treated NSCLC pts. Neutropenia is the main toxicity.

[Phase II study of docetaxel in inoperable advanced non small cell lung cancer].

The purpose is to determine the response to, and toxicity of docetaxel (Taxotère) in patients with inoperable non small cell lung cancer (NSCLC), previously untreated. Seventy patients with stage IIIB or IV NSCLC were treated by 100 mg/m2/ 3 weeks of docetaxel until tumor progression or severe toxicity. Premedication with diosmine and prednisolone was given in all patients: 66/70 were eligible and 55/70 were assessable for antitumoral activity. Median age: 63 years, WHO performans status 0-1: 83%, stage IV: 96%. For eligible patients, 17/66 (26%) achieved an objective response: 1 complete response and 16 partial response (IC 95% = 15-36). With a median follow-up of 23.4 months (range 14.9-28.7), for evaluable patients, the median response duration was 8 months, the median time to progression 4 months, and the median survival time 10 months. The median number of administered cycles is 5 (range 1-12). The estimate one year survival rate was 47%. Seventy-six patients presented neutropenia (grade 3-4); febrile neutropenia was observed in 7% of cycles. Non haematological toxicities are: fluid retention related to docetaxel (2.9%), diarrhea (6%), nausea-vomiting (4%), asthenia (3%), nail changes (6%). Docetaxel (Taxotère) administered at 100 mg/m2/3 weeks has relevant clinical activity in previously untreated NSCLC with a acceptable toxicity.

[Fortuitous discovery of infiltration of the lung bases].

We report a case of interstitial pneumonia found by a woman who suffered from a gastroesophageal reflux unamenable to usual treatments. The HR-tomographic discovery of a tone esophagus lead to a manometric study. The association of high autoantibodies levels and radiographic and manometric data were characteristic of esophageal and pulmonary scleroderma.

[Acute diffuse interstitial pneumopathy following docetaxel (Taxotère). Apropos of 2 cases].

Docetaxel, a new chemotherapeutic agent, has demonstrated activity in non-small cell lung cancer and breast cancer. Toxicities associated with treatment using docetaxel include hypersensitivity reactions and fluid retention, which can be prevented by pretreatment with corticosteroids. We describe herein two cases of acute interstitial pneumonitis after administration of docetaxel to patients suffering from metastatic non-small cell lung cancer. A pulmonary toxicity of docetaxel from an hypersensitivity reaction is likely because of symptoms course, radiological demonstration of an interstitial pneumonitis, lack of an infectious etiology and of clinical response to antibiotic treatment, and rapid recovery with corticosteroids. This unusual pulmonary toxicity has been rarely described with docetaxel, as transient pulmonary infiltrates have been observed during treatment with paclitaxel. The possibility of an hypersensitivity pneumonitis must be taken into account when a patient with docetaxel treatment presents pulmonary infiltrates.

[Peripheral venous catheter embolism].

The accidental embolization of peripheral venous catheter fragments seems to be a rare event. Removal of the catheter embolus is usually recommended, because of the high morbidity and mortality rates from sepsis, perforation, thrombosis and arrhythmias. We report a case, in which the diagnosis was made 17 years after the embolization by the means of a systematic chest X-ray. The use of spiral CT scan with computerized post-processing 3D reconstruction confirmed the diagnosis. Because of good tolerance during this very long term, a not-to-treat decision was taken.
