[Validation of the French version of the Princess Margaret Hospital Patient Satisfaction with their Doctor Questionnaire].
BACKGROUND: The evaluation of patient satisfaction receives increasing attention partly due to pressure from state agencies involved in the administration of health care. Outpatients' satisfaction with their doctor is a major component of total patient satisfaction. However, a validated instrument for assessing this has not previously been available in French. PATIENTS AND METHODS: The Princess Margaret Hospital Patient Satisfaction with Doctor Questionnaire (PMH/PSQ-MD) is a recently validated tool available in English for this purpose. A three-step procedure was conducted to obtain a validated French translation of the PMH/PSQ-MD. Subsequently, outpatients receiving chemotherapy, symptomatic treatment or attending a follow-up clinic were approached to participate in the study and complete the questionnaire. Acceptability and reliability (Cronbach's alpha score), as well as internal and external (Pearson correlation coefficient with the Patient Satisfaction Questionnaire IV) validities were studied. RESULTS: 137 patients were approached and 116 fully completed the study. The PMH/PSQ-MD's acceptability was high (<10% of non-responders). Internal validity was also high (Cronbach's alpha score > 0.7 for each dimension). External validity in comparison with the PSQ IV was high as well. Women demonstrated higher satisfaction scores, while age had no influence on patient satisfaction. CONCLUSIONS: The F-PMH/PSQ-MD is a questionnaire which addresses outpatients' satisfaction with their doctor, and is now available for research purpose as well as for daily practice.

Late pulmonary artery stump thrombosis with post embolic pulmonary hypertension after pneumonectomy.
Ten years after right pneumonectomy for primary lung cancer, a 51 year old man developed a pulmonary artery stump thrombosis which produced microemboli in the remaining lung and, in turn, led to chronic pulmonary hypertension. This case strongly suggests that prolonged postoperative thromboembolic prophylaxis should be considered in patients undergoing right pneumonectomy.

[Quality of life: attitudes and perspectives of doctors in a thoracic oncology regional care network].
BACKGROUND: The evaluation of health-related quality of life (HRQOL) of lung cancer patients is significant given their poor prognosis. Consequently, HRQOL is often currently assessed throughout clinical trials and sometimes in daily medical practice. The objective here was to determine physicians' perspectives on evaluating HRQOL. MATERIAL AND METHODS: The team carried out a prospective study of physicians belonging to a thoracic oncology network using an original questionnaire of 33 items. RESULTS: 102 physicians were questioned and 51 responded. Physicians' knowledge on HRQOL was frequently of a low level and incomplete, but most of them considered HRQOL as important HRQOL assessment in daily practice was often done intuitively. Many physicians noted that they lacked adequate time to explore and integrate all of the fields which should be covered by HRQOL in their clinical practice, but they felt overall that the HRQOL study improved doctor/patient communication and interaction. Physicians described an "ideal" HRQOL questionnaire as one containing 10-15 items within 6 domains (physical, psychological, general health, respiratory symptoms, family and social) and which could be completed in 5-8 minutes. In addition, such a questionnaire might integrate an opportunity for patients to isolate and identify items and issues that they consider to be most important to them. CONCLUSIONS: Physicians' will to consider and integrate the evaluation of HRQOL in the management of lung cancer patients is strong but meets some structural challenges (related to HRQOL assessment and interpretation of data) but also conjectural difficulties (with respect to a lack of knowledge). Training efforts are needed as well as the development of easier tools to facilitate the evaluation of HRQOL.

[Bronchoscopy in the diagnosis of lung cancer: an evaluation of current practice].
INTRODUCTION: Bronchoscopy is frequently practised by respiratory physicians, particularly when there is a suspicion of lung cancer. However, few guidelines are available and practice varies widely. BACKGROUND: Studies of current practice are few and unstandardised. Few data are available regarding equipment or procedure (information, prior investigations, environment, standardised reporting etc.). The evaluation of new techniques such as endobronchial ultrasound, autofluorescence bronchoscopy, transbronchial needle aspiration (TBNA) has been covered in recent publications. These evaluations are often undertaken without rigourous methodology (retrospective studies) but underline the feasibility of these techniques. Some, especially TBNA are nevertheless underused in practice. In the published studies evaluating practice the results of these investigations are often similar to those obtained in clinical trials even if a learning period is necessary. Complications are rare. Few studies of cost effectiveness are available but they support the use of these new techniques. VIEWPOINT: A national study under the aegis of the SLPF (French Respiratory Society) is necessary to obtain comprehensive and reliable data on the practice of bronchoscopy in the investigation of lung cancer. CONCLUSIONS: Studies evaluating current practices are few and unstandardised, and probably give only a partial survey of the success achieved and the difficulties encountered by respiratory physicians in their clinical routine.

Positive thyroid transcription factor 1 staining strongly correlates with survival of patients with adenocarcinoma of the lung.
This study investigated the relation between positive thyroid transcription factor 1 (TTF1) staining and survival of patients affected by primary adenocarcinoma (ADC) of the lung. Pathological tissue from consecutive ADC patients was collected from 2002 to 2004. The anti-TTF1 antibody (8G7G3/1, dilution of 1/200) was used. Thyroid transcription factor 1 staining was assessed for each tumour as positive or negative. Probability of survival was estimated by Kaplan-Meier and difference tested by log-rank test. A Cox's regression multivariate analysis was carried out. In all, 106 patients were studied (66% male, 69% PS0-1, 83% with stage III or IV). Tumours expressed positive TTF1 staining in 66% of cases. Multivariate analysis demonstrated an independent lower risk of death for patients whose tumour expresses positive TTF1 staining (HR = 0.51, 95% CI 0.30-0.85; P = 0.01) and higher grade of differentiation (HR = 0.40, 95% CI 0.24-0.68; P = 0.001). In conclusion, positive TTF1 staining strongly and independently correlates with survival of patients with primary ADC of the lung.

CYFRA 21-1 level predicts survival in non-small-cell lung cancer patients receiving gefitinib as third-line therapy.
Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) as gefitinib emerged as an accepted treatment in second- or third-line setting in NSCLC. However, clinical surrogate markers of EGFR-TKI activity in NSCLC patients remain to be identified and we studied the prognostic value of CYFRA 21-1 in this setting. Serum samples from 53 patients with NSCLC receiving gefitinib after failure of at least a platinum-containing regimen were prospectively collected from January 2002 to December 2003. Multivariate analysis demonstrated an independent negative impact on survival for a level of CYFRA 21-1 higher than 3.5 ng ml(-1) (HR=2.45, 95% CI 1.13-5.29; P=0.02). In conclusion, CYFRA 21-1 is a tool available to predict the survival of NSCLC patients receiving gefitinib as third-line therapy in an independent manner. In case of a CYFRA 21-1 level higher than 3.5 ng ml(-1), treatment with gefitinib needs further evaluation giving its relative poor effect on survival.

[Acute respiratory distress syndrome following inhalation of barium sulfate].
INTRODUCTION: Barium sulfate (BS) is chosen to explore swallowing disorders because of its reduced osmolality allowing no adverse reaction if aspirated in the bronchial tree. CASE REPORT: A 66-years old man treated for an advanced stage mesothelioma experienced a BS aspiration during an esophagography. He developed 3 days after an acute respiratory distress syndrome (ARDS) and deceased. The post-mortem examination revealed a diffuse alveolar damage (DAD). CONCLUSION: Whereas BS aspiration is generally well tolerated, serious adverse event as a DAD would exceptionally occurs. Thus, a close watch over respiratory symptoms has to be kept after BS administration, especially in debilitated and elderly patients.

[Prognostic indicators in stage I non-small cell lung cancer].
INTRODUCTION: Determinating the prognosis of patients with stage I non-small cell lung cancer (NSCLC) is a challenge. Since up to 30% of patients who have undergone surgical resection experience recurrence, generally in distant organs, it is reasonable to postulate that neo-adjuvant or adjuvant treatments might be useful. Better knowledge of prognostic factors could perhaps define which patient populations should be targeted with such treatments. STATE OF THE ART: Numerous potential prognostic factors, relating to the disease (TNM classification, histology, tumor size, blood vessels invasion, micro-metastasis, serum or molecular markers), the patient (gender, age, co-morbidity) as well as the treatment (delay, resection, lymph node dissection, neo-adjuvant and adjuvant treatments), are discussed. PERSPECTIVES: These prognostic factors should be integrated into the design of future clinical trials of chemotherapy and/or radiotherapy attempting to evaluate the effectiveness of various combinations of neo-adjuvant or adjuvant therapies. CONCLUSIONS: These factors may offer the opportunity to clinically and biologically characterize the different subgroups of patients, leading to a more rational, and perhaps individualized, choice of therapy.

[Disordered higher functions in a smoker].
INTRODUCTION: Paraneoplastic syndromes sometimes lead to the discovery of an intrathoracic tumour, notably small cell lung cancer (SCLC). MATERIALS AND METHODS: We report the case of a patient presenting with a paraneoplastic syndrome characterised by disordered higher functions and convulsions, representing a paraneoplastic encephalo-myelitis (PEM). This PEM led to the diagnosis of SCLC. The diagnostic features and progress of the PEM are discussed. CONCLUSION: Recognition of PEM allows the diagnosis and early treatment of the underlying cancer, strongly influencing the prognosis, particularly in SCLC.

[Acute pulmonary toxicity due to gemcitabine: a role for asbestos exposure?].
INTRODUCTION: Gemcitabine is an important drug in the treatment of non-small cell lung cancer. Myelosuppression is the most common toxic effect but its use sometimes leads to severe pulmonary toxicity by means of diffuse alveolar damage or sub-acute interstitial pneumonitis. METHODS: A retrospective study was made of all the patients treated in our department with this drug, alone or in combination. Episodes of acute dyspnoea during the course of chemotherapy were identified, and data were collected concerning the past history, the illness and the treatment in patients who had developed a respiratory failure attributable to gemcitabine. RESULTS: 312 patients had been treated with gemcitabine over a 5 year period and 18 had developed episodes of acute dyspnoea, of which 6 (1.9%) were attributed to the drug itself. Of these patients 4 had notifiable industrial disease (no. 30bis) secondary to asbestos exposure (odds ratio=85, 95% confidence interval 13-546) and 5 were active smokers. The possible role of intracellular ATP pool depletion secondary to asbestos exposure or smoking as a predisposing factor in the development of gemcitabine pulmonary toxicity is discussed. CONCLUSION: Smoking and asbestos exposure should be taken into account in future studies of gemcitabine pulmonary toxicity.

[Tolerance of fiberoptic bronchoscopy by self-administered questionnaire: in the words of the patients].
INTRODUCTION: Fibreoptic bronchoscopy is currently undertaken by the majority of respiratory physicians, but under varying conditions. Though complications are rare the tolerance of this examination is sometimes poor, particularly when it is performed under local anaesthesia. The undesirable effects may reduce the value of the examination as well as causing discomfort for the patient. METHODS: A prospective study of the tolerance of the endoscopic examination was made on 100 consecutive patients by self-administered questionnaire. RESULTS: There were no major and 7 minor complications (7%). 45% of the patients were anxious but the experience of the operator tended to reassure them (p=0.07). 30% of the patients reported some pain, which tended to be exacerbated by anxiety (44% vs 18%, p=0.008) and the supine position (57% vs 43%, p=0.047). 37% of patients reported nausea, and 50% dyspnoea, without any significant predictive factor. 79% would agree to a repeat examination under the same conditions and 92% said that they had received information appropriate to the examination undergone. CONCLUSION: The tolerance of fibreoptic bronchoscopy under local anaesthesia is poor and perhaps overestimated by respiratory physicians. Patient information is essential. A national enquiry could lead to the standardisation of techniques.

[Multiple pulmonary leiomyomatous nodules: benign metastasing leiomyoma?].
Pulmonary smooth muscle lesions are rare explaining their imperfect understanding. Two cases of multiple pulmonary leiomyomatous lesions in patients who previously underwent surgery for benign uterine leiomyoma are reported. Literature was reviewed to know if the controversial question of benign metastasising leiomyomas could be resolved. Therapeutic possibilities of this pathology are also discussed.
