Quality of life in lung cancer: does disclosure of the diagnosis have an impact?

BACKGROUND: Quality of life (QOL) is an important component of evaluation in oncology. Usually, QOL is used in phase III studies to compare two treatments. The aim of this trial was to evaluate the impact of the disclosure of the diagnosis of cancer on QOL by using the European Organisation for Research and Treatment of Cancer core Quality of Life Questionnaire (EORTC QLQ)-C30 questionnaire and the supplemental lung cancer-specific module QLQ-LC13. PATIENTS AND METHODS: Patients hospitalised for exploration of an abnormal chest X-ray, with no previous history of cancer, a performance status < or =2, and able to fulfil the questionnaire were eligible. The patients answered the questionnaire two times: before (Q1) and after (Q2) the disclosure of the diagnosis. RESULTS: Seventy patients answered at Q1 and Q2. After the disclosure, some scores deteriorated: arm pain (P=0.009), physical functioning (P=0.01), role functioning (P=0.008), emotional functioning (P=0.0001) and social functioning (P=0.012), whereas the patients' own assessment of global QOL (item global QOL in functioning scales) did not show the same evolution. CONCLUSION: Disclosure of the diagnosis had an impact on social and emotional QOL. Patients with lung cancer need psychological support at the beginning of their disease.

Detection of circulating cells expressing chromogranin A gene transcripts in patients with lung neuroendocrine carcinoma.

High grade lung neuroendocrine carcinomas, like small and large cell neuroendocrine carcinomas, pose therapeutic problems. Most initially respond to chemotherapeutic agents, but early relapses are frequent and are resistant to the presently available treatments. Our study reports for the first time the development and evaluation of a test for detecting the presence of circulating tumour cells by measuring chromogranin A gene transcripts with reverse transcriptase-polymerase chain reaction (RT-PCR) and Southern blotting. The test is specific and sensitive (detection of 10 cancer cells/ml blood), and only minimally invasive. Positivity is statistically correlated to high grade neuroendocrine carcinomas and to a poor prognosis with a 3-fold higher lethal risk. The test now needs to be assessed for its usefulness as a tool in the initial staging procedures and follow-up by comparison with the recent immunoradiometric assay (RIA) for detection of chromogranin A in the serum.

[Impact of smoking habits on the every day life of asthmatic adolescents]. / Influence du tabagisme sur la vie quotidienne des adolescents asthmatiques.

The impact of asthma on every day life is an important consideration in asthma management. Tobacco use often starts during adolescence, but little is known about its effect on the asthmatic process. The aim of this study is to describe the impact of smoking habits on the every day life of adolescents with asthma. A survey of respiratory symptoms in children aged 13-14 years was conducted in Bordeaux France as part of the International Study of Asthma and Allergies in Childhood (ISAAC). 494 out of the 3.302 adolescents surveyed had a diagnosis of asthma. They filled in a further questionnaire on smoking habits and on the impact asthma had on their every day life. Respiratory symptoms were more frequent among current smoking asthmatic adolescents than non-smoking asthmatic adolescents. The impact of asthma on daily life, with implications for performance at school, family life, psychological status and future job prospects were different for smokers and non-smokers, with problems more prevalent for active smoking asthmatic adolescents. In a multiple regression analysis with confounding factors adjustment, school absence was reported more often in active smokers. Active smoking has an important impact on the every day life of asthmatic adolescents.

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.

Phase I trial of gemcitabine and carboplatin in metastatic non-small-cell lung cancer: a Groupe Français de Pneumo-Cancérologie Study.

BACKGROUND: The purpose of this study was to determine the maximum-tolerated dose (MTD) and the dose-limiting toxicity (DLT) of the 21 days carboplatin plus gemcitabine regimen in previously untreated patients with stage IV non small-cell lung cancer (NSCLC). METHODS: At least three patients were entered at each dose level. The starting dose was carboplatin AUC 4 mg/ml per min (Area Under the Curve; Calvert formula) on day 1 and gemcitabine 750 mg/m(2) on days 1 and 8. Carboplatin was increased to AUC 5 (level 3, 4) then to AUC 6 (level 5-7). Gemcitabine was increased to 875 (level 2, 3), 1000 (level 4, 5), 1250 (level 6) and finally 1500 mg/m(2) (level 7). Twenty-nine patients were entered into this phase I study. RESULTS: At dose level 6, a DLT (grade 4 thrombocytopenia) was observed in one out of six patients. At dose level 7, no DLT was observed during the first course, so the MTD was not reached. During the second course, two out of four patients presented grade 4 thrombocytopenia. None of the five patients receiving two courses at level 6 presented a DLT, so this level was retained for further phase II studies. Of the 25 patients assessable for response, five achieved partial responses with a response rate of 20% (95% CI, 7 to 41%). The median survival time was 7 months and the 1-year survival rate was 24% (95% CI, 9 to 45%). CONCLUSION: The combination of carboplatin given on day 1 and gemcitabine given on days 1 and 8 every 3 weeks seems to be an acceptable regimen. The DLT consists exclusively of severe thrombocytopenia. Despite the MTD was not reached with carboplatin AUC 6 mg/ml per min and gemcitabine 1500 mg/m(2), the recommended dose for further phase II studies is carboplatin AUC 6 mg/ml per min and gemcitabine 1250 mg/m(2).

Spontaneous pneumothorax: pragmatic management and long-term outcome.

We prospectively considered 65 patients admitted for a spontaneous pneumothorax (SP) to describe the pragmatic management of SP, the first recurrence-free interval after medical therapeutic procedure and to specify the first recurrence risk factors over a 7-year period in these patients treated medically. The treatment options were observation alone (9%), needle aspiration (6%), small calibre chest tube (Pleurocatheter) drainage (28%) or thoracic tube drainage (49%), and pleurodesis with video-assisted thoracic surgery procedure (8%). Duration of the drainage and length of hospital stay were shorter in the Pleurocatheter group than in the thoracic tube group (P < 0.01). Among the 47 patients (72%) with a first SP and treated medically, nine patients (19%) had a first homolateral recurrence (FHR) during a mean follow-up of 84+/-13 months. Recurrence-free intervals ranged from 1 to 24 months (mean +/- SD: 9.3+/-8.4 months). FHR cases were more frequent in the Pleurocatheter group (P < 0 04). Analysis of potential risk factors showed that the patient's height and a previous homolateral SP episode are independent recurrence risk factors.

CT-guided transthoracic needle biopsy of pulmonary nodules smaller than 20 mm: results with an automated 20-gauge coaxial cutting needle.

AIMS: To evaluate the efficacy and the complication rate of CT-guided percutaneous lung biopsy of pulmonary nodules smaller than 20 mm in diameter using a 20-gauge coaxial automated biopsy device. MATERIAL AND METHODS: A prospective study was undertaken of 200 patients who underwent 202 consecutive biopsies of pulmonary nodules, performed with a single type of automated biopsy device. Sixty-seven biopsies of nodules smaller than 20 mm in diameter were performed in 66 patients (group A). One hundred and thirty-five biopsies of lesions of 20 mm or greater in size were performed in 134 patients (group B). Patient characteristics, lesion and procedure variables, the accuracy and complication rates were compared. RESULTS: In group A, the final diagnosis of the nodules was malignant in 47 and benign in 19 cases (prevalence of malignancy 71. 2%). In group B, there were 111 malignant and 21 benign diagnoses (prevalence of malignancy 82.2%). In group A, the sensitivity and specificity for a diagnosis of malignancy were 89.5 and 100%, respectively (positive predictive value 100%, negative predictive value 76%). A specific diagnosis of benignity was obtained in nine out of 19 (47%) biopsies. The pneumothorax rate was 15% (10 patients) of which two (3%) required drainage. CT signs thought to reflect alveolar haemorrhage were noted in 28 (43%) and haemoptysis occurred in five patients (5.9%). In group B, the sensitivity and specificity for a diagnosis of malignancy were 95.5% and 100%, respectively (positive predictive value 100%, negative predictive value 82.7%). A specific diagnosis of benignity was made in 14 cases (58.3%). Complications included pneumothoraces in 22 cases (16.2%) requiring drainage in one (0.7%). Presumed alveolar haemorrhage was recorded in 19 cases (14.1%) and haemoptysis occurred in seven (5. 2%). There were no significant differences between group A and group B, except for alveolar haemorrhage (P < 0.001). CONCLUSION: The accuracy and complication rate of percutaneous CT-guided biopsy of nodules smaller than 20 mm, performed using an automated 20-gauge coaxial biopsy device, are comparable to those for larger lesions.

[High-dose ifosfamide in patients with stage IV non-small cell lung cancer: phase II trial from the Groupe français de pneumo-cancérologie (GFPC)]. / Ifosfamide à forte dose chez des patients porteurs de cancers bronchiques non à petites cellules de stade IV: essai de phase II du Groupe français de pneumo-cancérologie (GFPC).

PURPOSE: To assess the toxicity and efficacy of high dose ifosfamide in stage IV NSCLC. METHODS: In a previous trial, we have determined maximum tolerated dose for 3-days ifosfamide treatment by 3-weeks schedule as 9 g/m2 according to hematologic tolerance. We therefore set up a phase II to study the toxicity and efficacy of this schedule in chemotherapy naive metastatic NSCLC. Ifosfamide (+ mesna 1 g/m2) was administered by a two hour infusion (3 g/m2) for three days every three weeks. Patients received three mesna bolus infusions (1 g/m2) at 4, 8 and 12 hours after the end of ifosfamide infusion. Antitumoral efficacy was performed after 2 cycles and treatment could be pursued for responding patients until disease progression. From september 1995 to January 1997, 31 patients have been included in this study. Median age was 60.7 years +/- 1.33 (41-70) for 27 males and 4 females. Patients (pts) presented metastases in lung for 10 pts, bone for 10 pts, liver for 6 pts, adrenal for 4 pts and multiorgan metastatic localisation for 1 patient. Seven patients were unassessable: 1 lost for follow-up, 1 sudden death, 5 treatment interruptions before evaluation time and 3 toxic deaths (9.6%). TOXICITY: neutropenia grade 4 (10 pts and 1 death), cardiotoxicity grade 4 (1 pt) and 2 deaths following neurotoxicity grade 4. We achieve 4 partial responses (13%, 95CI: 3.6-29.8), 10 progressive diseases (32.3%, 95CI: 16.7-51.4) and 10 stabilizations (32.3%, 95CI: 16.7-51.4). Median response duration was 91 days +/- 55 d. Median survival was 9.3 months, e.g. 280 days (8-863). Overall survival at one year is 48%. CONCLUSION: This modality of high dose ifosfamide is as effective as standard monotherapy schedules in stage IV NSCLC. Unexpected toxicities particularly hematological ones could be due to a short duration of fractionated treatment. Results in term of survival leads us to further evaluate ifosfamide monotherapy treatment on a 5-day schedule basis.

[Osmolarity of solutions used in nebulization]. / Osmolarité des solutions utilisées en nébulisation.

Inhaled medications are widely used in patients suffering from bronchial diseases. Beside their pharmacological properties, nebulised solutions have physico-chemical characteristics that can alter bronchial reactivity. Non-isotonic solutions can induce a bronchial hyperresponsiveness and/or a severe bronchonconstriction. Nevertheless, multiple drugs are used for nebulisation despite their unknown osmolarity. The aim of this study was to measure the tonicity of drug solutions commonly used for nebulisation in patients suffering from bronchial disease. Drug solutions were prepared either according to manufacturer recommendations or by diluting the stock in 5 ml of NaCl (0.9%) or H2CO3 (0.14%). Although bronchodilatator solutions (i.e. salbutamol, terbulatine, ipratropium bromide) were nearly isotonic, some drugs prepared for nebulisation had either a very high (e.g. mesna, netilmicine) or a very low (e.g. gomenol, sodium cromoglycate) tonicity. These values may be responsible for bronchoconstriction. Some hypertonic solutions, prepared with drugs such as acetylcytein or netilmycin, are not commercialised for nebulisation but are commonly used for aerosol therapy. In addition, solutions initially isotonic could become significantly hypertonic towards the end of nebulisation. Taken together, these results suggest that non-isotonic solutions should be used with caution specially in patients with bronchial hyperresponsiveness, even when aerosol therapy is prescribed for upper airways.

[Presumed transudative pleural effusion?]. / Vous avez dit transsudat?

We report a case of recurrent transudative pleural effusion. The initial cardiovascular investigations failed to determine its cause. The catheterization showed a "dip-plateau" suggesting a restrictive cardiomyopathy. Endomyocardial biopsy finally proved a cardiac amyloidosis.

[Isolated pulmonary choriocarcinoma]. / Choriocarcinome pulmonaire isolé.

The author report a case of isolated choriocarcinoma of the lung revealed in a young woman by a tumoral syndrome of the right base with haematoma. The diagnosis of isolated pulmonary choriocarcinoma was based on the lack of previous gynaecological history and tumour, on the singleness of the lung tumour at CT, and on the high initial beta-CGH level (3,300 ng/ml) in the absence of pregnancy. Surgical resection confirmed the diagnosis and lowered the beta-CGH level to 7 ng/ml. The various aetiopathogenic theories put forward and their relations with the prognosis disparity found in the literature are reviewed. The authors compare the prognosis of isolated pulmonary choriocarcinoma in a non-nulliparous woman to that of placental choriocarcinoma.
