[Phase II trial evaluating the effect of megestrol acetate-prednisolone combination in the treatment of anorexia during the palliative-care phase of lung cancer].

OBJECTIVES: Anorexia is one of the most frequent complaints in patients who have reached the palliative-care phase of lung cancer. Megestrol acetate (or medroxyprogesterone acetate) and corticosteroids have been used with success, but the effect of their combination remains unknown. We conducted a phase II trial to assess the impact of combination therapy. PATIENTS AND METHODS: Patients with lung cancer given palliative care and who developed anorexia with or without weight loss were given 320 mg/d megestrol acetate in 2 doses and 40 mg/d prednisolone in one dose in the morning for 1 month. The principal outcome criterion was anorexia assessed on a visual analog scale prior to treatment and then at day 15 and day 30. Variation in daily calorie intake and weight were also recorded. We used an Armitage sequential plan to determine the number of inclusions necessary and the preference method (closed schema) to evaluate the principal outcome criterion. RESULTS: Inclusions were stopped after the eighth patient (giving p<0.05) as we observed a significant improvement in patient appetite. Daily calorie intake improved significantly (p<0.0001), by 39.18% the first 15 days and 16.57% more the next 15 days. Body weight improved significantly by 5.4% in one month (p=0.5). No treatment-related complication occurred during the study period or during the six consecutive months. CONCLUSIONS: The megestrol acetate-prednisolone combination was found to improve anorexia in patients with lung cancer in the palliative-care phase and allowed a significant improvement in calorie intake and body weight.

[Endodermal pulmonary tumor resembling a fetal lung].

We report a case of a 56-year-old man who developed a flu-like syndrome associated with weight loss. Chest X-ray revealed a homogeneous round lesion of the lung with sharply defined margins in the central lobe. At pathology, the tumor was found to be an endodermal pulmonary tumor resembling a fetal lung. This uncommon tumor is generally a fortuitous chest X-ray finding seen as a rounded peripheral opacity. Diagnosis is based on pathology examination of the surgical specimen. Complementary investigations are not contributory. Unlike blastoma, a differential diagnosis, prognosis is generally good.

[Severe pneumonia with a pneumococcal aspect during an ornithosis outbreak].

OBJECTIVES: To describe the clinical, radiological and biological features of Chlamydia psittaci pneumonia. METHODS: A pneumonia outbreak occurred in a healthy middle-aged population working in a poultry slaughterhouse. Systematic serology (2 samples at 5 weeks intervals) provided the diagnosis of Chlamydia psittaci pneumonia in 6 patients. Patient files were analyzed retrospectively. RESULTS: The clinical presentations in this series of pneumonia were particularly homogeneous with a pneumococcal profile in all 6 cases: sudden onset, temperature above 39 degrees C, lobar alveolar involvement, hypoxemia, hyperleukocytosis and liver dysfunction. One case of hallucinatory delirium was observed. The patients were given spiramycin (9 million units per day for 3 weeks) and all recovered rapidly with no complications. CONCLUSION: The unusual virulence of the Chlamydia psittaci and very important inoculum were probably involved in this outbreak because of the severity of the pulmonary features and the short exposure of some patients to the bacteria. These cases suggest that the prevention of ornithosis in poultry slaughterhouses should be reinforced.

[Angiosarcoma of the thoracic wall revealed by hemothorax].

Angiosarcoma is an uncommon tumor accounting for approximately 1% of all soft tissue tumors which, themselves account for 0.7% of all malignant tumors. Thoracic parietal localizations are reported exceptionally and prognosis is poor. We report the case of a 79-year-old woman who developed an angiosarcoma of the thoracic wall. The inaugural symptom was a hemothorax. Besides the localization, this case was particularly exceptional since the patient has remained asymptomatic three years after treatment by wide resection followed by radiotherapy.

[Relieving the obstruction caused by malignant tracheobronchial tumors under flexible endoscopy].

OBJECTIVES: We evaluate the feasibility and the efficiency of electrosurgery in the treatment of the symptomatic malignant tracheobronchial tree obstructions (MTTO) when it is used with flexible fiberoptic bronchoscopy without general anesthesia. METHODS: The aim of electrosurgery was to restore the permeability of the tracheobronchial tree to suppress symptoms. The operation lasted no more than 60 minutes, and a second operation was performed 8 days later if symptoms persisted. The patients received local anesthesia and light sedation (midazolm). PATIENTS: 28 patients have been treated from june 1995 to june 1996 for following symptoms: dyspnea (22 cases), cough (1 case), dyspnea and cough (5 cases). All patients had malignant disease palliatively treated. RESULTS: The protocol has failed in one case, needing general anesthesia. 27 patients have had one session, 6 a second one week later. After the first session, dyspnea was improved in 22/27 cases (81.5%) and cough in 5/6 cases (83%). After the second session, dyspnea was globally improved in 26/27 cases (96%), without change for cough. CONCLUSION: Electrosurgery is a feasible and safe treatment which can implement immediately without general anesthesia, in MTTO. Its result are highly effective on dyspnea but less on cough, with reproducible effects and a well-tolerated procedure. Further investigations need to compare the different techniques.

[Anorexia associated with bronchial cancer].

Anorexia is a frequent complaint in patients suffering from bronchial cancer. It is linked to multiple factors, organic, biological and psychological. The treatment of anorexia implies an involvement with all these factors. If it persists, it may be improved by corticosteroids or by derivatives of progesterone independently of the control of the tumour process.

[Prognostic value of flow cytometry in squamous cell bronchogenic cancer. A retrospective study of 61 cases].

To assess the prognostic value of flow cytometric analysis, 61 cases of operated squamous cell lung carcinoma were studied in terms of desoxyribonucleic acid (DNA) nuclear content and percentage of cells in DNA synthesis phase (% S). These parameters were determined on a fresh surgical sample. The S % was obtained in 25 cases. DNA index (DI) and % S were compared with survival and usual clinicopathologic characteristics for the prediction of survival. DNA content classified as DNA-diploid and DNA-aneuploid is not a prognostic factor for survival. DI higher than 2 seems to be predictive but needs confirmation. The % S and multiploidy are not predictive factors for survival.

[Surgical vein reconstruction in patients with tumor invasiveness of the superior caval system. Retrospective study of 7 cases].

We studied retrospectively all patients who underwent vascular reconstruction after tumor invasion of the superior vena cava in order to assess the surgical procedure. Seven patients were operated including 5 with compression of the superior vena cava. Compression regressed within 24 hours without recurrence. Reconstruction had no effect on morbidity and mortality. One patient is still alive after a 5 year follow-up. Invasion of the superior vena cava is not a contraindication for resection of a tumor localized in the thorax and may contribute to cure as it improved patient comfort in all cases.

[Evolvements in the presentation of primary bronchial adenocarcinomas observed in a pneumology service over an 11-year period].

The evolution of the clinical presentation, endoscopy and radiology in a consecutive series of 121 cases of primary bronchial adenocarcinoma has been studied in a retrospective manner over a period of 11 years. The mean age was 60 +/- 12 and 16.5% of the patients were women. The frequency of smoking and the quantity smoked in packed years was significantly higher in men than in women. The frequency of the presenting signs and the endoscopic features did not change over the period. On the other hand, the peripheral and mediastinal-hilar forms were more frequent from 1990 in a significant manner so that the hilar form became rarer. The result seems to confirm an increase in the frequency of a new radio-clinical expression of primary bronchial adenocarcinoma. These mediastinal-hilar adenocarcinomas do not have specific characteristics but are associated with a higher mortality.

[Prognostic evaluation of small cell lung carcinoma by flow cytometry. A retrospective study from bronchial brushing samples].

The authors determined the desoxyribonucleic acid (DNA) content of 45 small-cell lung cancers, by flow-cytometry (FC), from bronchial brushings to asses the prognostic meaning of the DNA index, the percentage of cells in DNA synthesis phase (% S) and the ploidy. Moreover, the value of this tumorous cells brushing was assessed for Flow-cytometric analysis. Bronchial brushing offers some advantages opposite to biopsies, but the low quantity of collected cells reduces the number of tumors analysable by FC. The output is low (39%) for determination of DNA index, and moreover low (22%) for determination of % S. In regard to the flow-cytometry analysis, the DNA content does not show any significant difference of survival where as the % S is related to survival, but it seems to be paradoxical in this study. Indeed, patients with small-cell lung cancer associated to high cells' percentage in DNA synthesis phase have the longest survival.

[Can outcome of varicella pneumonia be predicted in a non-immunosuppressed patient?].

Varicella rarely occurs in the adult but can cause multi-organ complications. The most frequent (15 to 30% involve varicella pneumonia of unpredictable outcome. In the healthy adult, outcome can be favourable in 5 days or inversely lead to respiratory distress and death in 10 to 20% of the cases. An analysis of the published cases does not reveal any factor predicting unfavourable outcome. A register of varicella pneumonia would help identify potential predictive factors.

[Contribution of flow cytometry in the prognostic evaluation of non-small-cell lung cancers. Review of the literature].

The flow-cytometry (FCM) is a method of quickly determining the desoxyribonucleic acid (DNA) content of tumoral cells. This provides us with two results: the DNA-ploidy which characterizes quantitatively the DNA, and the percentage of cells in DNA synthesis phase (%S). The contribution of FCM in evaluation of the prognosis of non-small cell lung cancer remains disputable. The absence of standardization between laboratories makes it difficult to compare the different studies to define the place of FCM analysis. However, for epidermoid carcinomas, the most actively studied, a DNA diploidy and a weak %S have a favourable impact on survival. No conclusion can be drawn from the studies on adenocarcinomas. Large cell carcinomas have never been studied in an isolated manner, due to the lack of numbers.
