Coexisting pulmonary nodules in operable lung cancer: prevalence and probability of malignancy.

INTRODUCTION: Coexistence of pulmonary nodules in operable non small cell lung cancer (NSCLC) may influence the therapeutic indication. The aim of this study was to evaluate prospectively the prevalence and the probability of malignancy of pulmonary nodules in operable lung cancer. METHODS: From a prospective database, all surgically treated patients diagnosed with NSCLC from 1998 to 2003 were retrospectively reviewed. Patients presenting pulmonary nodule(s) were identified. RESULTS: Two hundred thirty nine patients had a complete resection for a NSCLC and 56 patients (24%) presented altogether 88 nodules on thoracic CT. Twenty-four of these nodules (27%) were malignant, 28 (32%) benign and 36 (41%) of undetermined nature. Five factors associated with nodule's malignancy were identified: tumour histology (non-squamous (non-SCC) 44% vs. SCC 7%, p=0.001), localization of the nodules in an upper lobe (vs. other lobe, p=0.004), co localization in the same lobe as the NSCLC (vs. another lobe, p=0.03), nodule size (p=0.05) and shape (speculated vs. non spiculated, p=0.02). From these factors, a probability score was assessed with a malignancy rate in SCC of 0% in nodules presenting ≤ 1 feature, 33% with 2 features and 100% with ≥ 3 features and in non-SCC of 40% with 1 feature, 82% with 2 features and 100% with 3 ≥ features. CONCLUSION: Diagnosis of satellite nodules associated with early stage NSCLC is common. We developed a predictive score to estimate the probability of malignancy which may be a precious aid in the management of pulmonary nodules associated to a NSCLC.

[Very late malignant complications of Hodgkin lymphoma]. / Complications malignes très tardives d'un lymphome de Hodgkin.

Overall survival of patients with Hodgkin lymphoma has dramatically increased in recent years, with an increased rate of malignant complications. We report here a 54-year-old man who presented with concomitant relapse of classical Hodgkin's lymphoma and lung adenocarcinoma 20 years after initial treatment with chemotherapy and mantle radiotherapy. Pathogenic mechanisms of these malignant complications are discussed. A prolonged follow-up of patients with Hodgkin's lymphoma is required.

[Oral erosive lichen planus associated with Good syndrome]. / Lichen plan buccal érosif associé à un syndrome de Good.

INTRODUCTION: Good syndrome is characterized by thymoma, hypogammaglobulinemia, low number of peripheral B cells, and variably, peripheral CD4 T cell lymphopenia and inverted CD4/CD8 T cell ratio, associated with infections and autoimmune diseases. CASE REPORT: We report an 85-year-old woman who presented with oral erosive lichen planus and thymic tumor. Improvement of oral erosive lichen planus was observed after resection of a benign thymoma, but was ineffective on the immunodeficiency syndrome. Only 11 patients with Good syndrome and lichen planus have been previously reported and are reviewed. CONCLUSION: The association of oral erosive lichen planus with Good syndrome is rare, but does not seem to be fortuitous.

[Bevacizumab and invasive procedures: practical recommendations]. / Bevacizumab et actes invasifs: recommandations pratiques.

As first line chemotherapy Bevacizumab, associated with a platinum based regime, improves survival in patients with metastatic, non small cell, non epidermoid bronchial carcinoma. Marketing authorization for this indication was obtained in 2007. This treatment produces specific secondary effects related to its anti-angiogenic action. Physiologically, vascular endothelial growth factor (VEGF) is important in the process of scar formation. Bevacizumab inhibits scar formation and may encourage bleeding. The aim of this article is to analyse the specific risks associated with invasive procedures and to produce practical recommendations. Unfortunately there are few data in the literature. We depend, therefore, principally on studies of neo-adjuvant chemotherapy in metastatic colo-rectal cancer prior to excision of hepatic metastases and on our own experience of excision of pulmonary metastases from solid tumours treated with bevacizumab. We recommend a delay of 2 days between implantation of an intravenous device and the initiation of bevacizumab, a delay of at least 5 weeks between the last injection of bevacizumab and invasive surgery and a delay of 4 weeks between surgery and the initiation of bevacizumab treatment. Obviously, referral to a medico-surgical team experienced in the management of these patients is strongly recommended.

[Bronchopulmonary aspergillosis infections in the non-immunocompromised patient]. / Infections aspergillaires broncho-pulmonaires du sujet non immunodéprimé.

The definition of broncho-pulmonary aspergillosis infections in non-immunocompromised patients remains vague and a wide range of clinical, radiological and pathological entities have been described with a variety of names, i.e. simple aspergilloma, complex aspergilloma, semi-invasive aspergillosis, chronic necrotizing pulmonary aspergillosis, chronic cavitary and fibrosing pulmonary and pleural aspergillosis, pseudomembranous tracheobronchitis caused by Aspergillus, and invasive aspergillosis. However, these disease entities share common characteristics suggesting that they belong to the same group of pulmonary aspergillosis infectious disorders: 1- a specific diathesis responsible for the deterioration in local or systemic defenses against infection (alcohol, tobacco abuse, or diabetes); 2- an underlying bronchopulmonary disease responsible or not for the presence of a residual pleural or bronchopulmonary cavity (active tuberculosis or tuberculosis sequelae, bronchial dilatation, sarcoidosis, COPD); 3- generally, the prolonged use of low-dose oral or inhaled corticosteroids and 4- little or no vascular invasion, a granulomatous reaction and a low tendency for metastasis. There are no established treatment guidelines for broncho-pulmonary aspergillosis infection in non-immunocompromised patients, except for invasive aspergillosis. Bronchial artery embolization may stop hemoptysis in certain cases. Surgery is generally impossible because of impaired respiratory function or the severity of the comorbidity and when it is possible morbidity and mortality are very high. Numerous clinical cases and short retrospective series have reported the effect over time of the various antifungal agents available. Oral triazoles, i.e. itraconazole, and in particular voriconazole, appear to provide suitable treatment for broncho-pulmonary aspergillosis infections in non-immunocompromised patients.

[Management of severe hemoptysis: experience in a specialized center]. / Prise en charge des hémoptysies graves: expérience d'un centre spécialisé

Bronchiectasis, cancer and tuberculosis account for the majority of haemoptysis requiring intensive care unit admission. Bedside evaluation (volume and bronchoscopic active bleeding) is safe to screen patients for arteriography and bronchial artery embolisation (BAE). First-line interventional arteriography should be favour over surgery in patients with non traumatic life-threatening hemoptysis. Surgery must be reserved in cases of failure or recurrence of bleeding after BAE.

[Tracheal replacement using the abdominal aorta. Comments on a case report]. / Remplacement de la trachée par l'aorte. Réflexions à propos d'un cas.

Tracheal replacement is an uncommon option because of the very limited number of indications and the large number of possibilities for resection anastomosis. There may nevertheless be situations were extensive resection leaves only one solution, tracheal replacement. To date, no prosthesis has provided long-term satisfaction. For tracheal replacement, the prosthesis must provide a large caliber airway which does not collapse during expiration and which enables the development of a ciliary lining, in addition to tolerance without rejection. Recent experimental work, then several clinical cases, would suggest that the abdominal aorta can be successfully transformed into a neotrachea. A temporary endoprosthesis is however necessary to prevent collapse until new tracheal rings develop. Experimental and early clinical work has provided promising results but with problems concerning the endoprosthesis. In our patient, we used the abdominal aorta as a tracheal substitute but replaced the endoprosthesis with an exoprosthesis leaving the aortic lumen free. The result was also encouraging, but the absence of integration of the aortic tissue did not confirm the observations reported by others. Other hypotheses concerning the regeneration of the neotrachea should be put forward.

[Exogenous lipoid pneumonia associated with pulmonary and hepatic sarcoidosis]. / Pneumopathie lipidique exogène associée à une sarcoïdose systémique avec atteinte hépatique nodulaire.

INTRODUCTION: In a patient with basal alveolar shadowing the diagnosis of exogenous lipoid pneumonia (ELP) requires a past history of chronic ingestion of liquid paraffin and the presence of numerous macrophages containing oil droplets in the bronchial lavage (BL). Additional radiological abnormalities suggest an associated disease, notably infection or cancer, as has been described in the literature. CASE REPORT: We report the case of a 50 year old woman presenting with alveolar shadowing in the left lung associated with ipsilateral mediastinal nodes and a pleural effusion in addition to two hepatic nodules. As the diagnosis of ELP did not explain the radiological features a thoracotomy and liver biopsies were performed. Histological examination of the hepatic, pulmonary and lymph node biopsies excluded cancer and mycobacterial disease and showed a florid granulomatous foreign body reaction associated with pulmonary and hepatic sarcoidosis. After a 3 month course of oral corticosteroids the mediastinal lymphadenopathy, pleural effusion and hepatic nodules resolved. The patient has maintained her recovery without further treatment for 4 years. CONCLUSION: The final diagnosis was ELP and systemic sarcoidosis with nodular hepatic involvement.

[Spontaneous hemothorax: a rare but serious complication of intralobular pulmonary sequestration]. / Un hémothorax spontané: complication rare mais grave d'une séquestration pulmonaire intra-lobaire.

Pulmonary sequestration is a rare congenital malformation characterized by a non-functional portion of pulmonary parenchyma devoid of any connection with the bronchial tree and pulmonary artery. If not identified antenatally or at birth, the sequestration may not be discovered until complications, mainly repeated infections, arise. Hemorrhage is another but much rarer complication which is generally severe. We report a new case of intralobular pulmonary sequestration revealed by hemoptysis then massive hemothroax with shock requiring emergency thoracotomy for hemostasis.

[Left strangulated diaphragmatic hernia: an unusual complication of gastric bypass]. / L'anneau gastrique: cause inhabituelle de hernie diaphragmatique gauche étranglée.

The appearance of left strangulated diaphragmatic hernia doesn't seem to have been described in the past as a progressive complication after gastric bypass surgery. The authors describe the case of a 54 year old patient suffering from a strangulated gastric hernia pushing through a diaphragm defect located next to the gastric band. The gastric band had been placed two years previously in this patient suffering from morbid obesity. Strangulation of the hernia resulted in the sphacelation of the entire stomach fundus. Therefore a partial gastrectomy and removal of the band was necessary. Recovery from procedure was without complications. The past history of a major spinal trauma in this patient, could have led to a discussion regarding the etiology of this hernia, however the delay between the two events (28 years) makes this unlikely. It seems, therefore, that the placement of a gastric band was the responsible factor. The authors emphasize the importance of pre-procedure pulmonary X-ray, prior to any general anesthesia, as well as a post procedure cliché following any intervention that might have lead to diaphragmatic lesion.

[An exceptional but serious complication of benign intercostal schwannoma: hemothorax]. / Une complication exceptionnelle mais grave du schwannome intercostal bénin: l'hémothorax.

Spontaneous serious hemothorax has not been described previously as an inaugural signor secondary complication of benign intercostal schwannoma. We report a case in a 45-year-old woman who was hospitalized in an emergency setting after development of massive left hemothorax. After evacuation of the effusion, imaging demonstrated a voluminous apparently neurogenic tumor in an intercostal position. Thoracotomy was required for hemostasis due to persistent bleeding. Tumor resection was performed. At histology, the surgical specimen was found to be a benign schwannoma presenting hemorrhagic remodeling. Resection provided complete cure with no sequelae. This secondary complication favors resection of benign intercostal schwannoma.

[Moderately abundant hemoptysis revealing endobronchial hamartochondroma]. / Une hémoptysie de moyenne abondance révélant un hamartochondrome endobronchique.

Hemoptysis is rarely the inaugural sign of endobronchial hamartoma. Abundance may range from moderate to massive, and may be life-threatening. We report the case of a 44-year-old woman who was referred to our center with moderate and persistent hemoptysis. A left upper lobe lobectomy was performed. We discuss the therapeutic options in such cases.

[Intrapulmonary rupture of a dermoid cyst: MRI findings]. / Rupture intra-pulmonaire d'un kyste dermoïde du médiastin: aspect IRM.

We report a case of dermoid cyst of the mediastinum ruptured into the lung. Only a few reports of ruptured mediastinal dermoid cyst have appeared in the literature. A 18-year-old female patient developed a tumor in the anterior mediastinum, which was coincidentally detected by a conventional chest X-ray. CT and MRI demonstrated two components: a cystic mediastinal mass and adjacent parenchymatous condensation. The cystic mass (no enhancement during or after injection) had a fatty structure: high-intensity T1 signal and low-intensity T2 signal. The thin wall (low-intensity signal on T1 and T2) was strongly enhanced during the systemic time and was ruptured. The parenchymatous condensation included a fatty effusion and an inflammatory reaction with the same T1 signal as the cyst, remaining slightly hyperintense on T2 with enhancement after injection. Cine-MRI demonstrated that the mass and the compressed right atrium were independent.

[Retrotracheal cystic mass in the mediastinum]. / Masse médiastinale kystique rétro-trachéale.

We describe a case of retro-tracheal mass of the visceral compartment of the mediastinun in a 79-year-old woman revealed by signs of tracheal compression. Visualization of a vascular image coming from the cervical zone on reconstructed injected CT, and biological demonstration of a primary hyperparathyroidism led to the diagnosis of ectopic parathyroid adenoma, in spite of the cystic aspect of that tissular mass. Surgery by cervical approach was able to remove this mass without any problem. Pathological examination confirmed that it was a parathyroid adenoma with necrotic modifications. Follow up show a clinical and a biological improvement.

[Standards, Options and Recommendations for the management of stage I or II primary bronchial cancers treated exclusively with radiotherapy]. / Standards, Options et Recommandations pour la prise en charge des patients atteints d'un cancer bronchique primitif de stade I ou II traités par irradiation exclusive.

CONTEXT: The 'Standards, Options and Recommendations' (SOR) project, started in 1993, is a collaboration between the Federation of the French Cancer Centres (FNCLCC), the 20 French cancer centres and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and outcome for cancer patients. The methodology is based on literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. OBJECTIVES: To develop clinical practice guidelines according to the definitions of the Standards, Options and Recommendations project for the management of stage I and II non small cell lung carcinoma treated by radiotherapy alone. METHODS: Data were identified by searching Medline and personal reference lists of members of the expert groups. Once the guidelines were defined, the document was submitted for review to independent reviewers, and to the medical committees of the 20 French cancer centres. RESULTS: The main recommendations for the management of stage I and II non small cell lung carcinoma treated by radiotherapy alone are: 1) The curative external irradiation with a continual course is an alternative to surgery only in the case of medically inoperable tumors or because the patient refuses surgery; 2) The external irradiation of the primary tumor only without the mediastinum could be proposed in peripheral stage IA. In proximal stage IA and IB, external irradiation should be carried out only as part of prospective randomised controlled trials comparing a localised irradiation of the primary tumor with a large irradiation of the mediastinum and the primary tumor. The treated volume must include the macroscopic tumoral volume with or without the microscopic tumoral volume and with a security margin from 1.5 to 2 cm; 3) There is a benefit to delivering a total dose in the primary tumor higher than 60 Gy in so far as the proposed irradiation, taking into account the respiratory function, does not increase the likelihood of severe adverse events due to radiation; and 4) The change in fractionation, the radiochemotherapy combination, the endobronchial brachytherapy with high dose rate alone or with external irradiation could be proposed only as part of prospective controlled trials for tumors classified as stage IB or II.

[Standards, options and recommendations for the management of locally advanced non small cell lung carcinoma]. / Standards, otions et recommandationspour la prise en charge thérapeutique des patients atteints d'un cancer bronchopulmonaire primitif non à petites cellules localement avancé.

CONTEXT: The "Standards, Options and Recommendations" (SOR) project, started in 1993, is a collaboration between the Federation of the French Cancer Centres (FNCLCC), the 20 French Cancer Centres and specialists from French Public Universities, General Hospitals and Private Clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and outcome for cancer patients. The methodology is based on literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. OBJECTIVES: To develop clinical practice guidelines according to the definitions of the Standards, Options and Recommendations project for the management of locally advanced non small cell lung carcinoma. METHODS: Data were identified by searching Medline and the personal reference lists of members of the expert groups. Once the guidelines were defined, the document was submitted for review to independent reviewers and to the medical committees of the 20 French Cancer Centres. RESULTS: The main recommendations are: 1) The management of the locally advanced non small cell lung carcinoma has two main goals: firstly to obtain local control of the disease (or to at least delay local progression in order to improve the survival or relapse free survival), and secondly to prevent the development of metastases. 2) There is a consensus that locally advanced non small cell lung carcinoma should be irradiated. External beam radiotherapy should be of optimal quality and delivered at a minimal dose of 60 Gy by standard fractionation. For patients with a poor life expectancy, this can be delivered as a split-course or hypofractionated scheme. 3) Treatment for patients with a performance status of 0-1 should consist of short duration induction chemotherapy (with a least two drugs one of which must be cisplatin), combined sequentially with conventional radiotherapy. 4) Surgery is contraindicated in extensive N3 disease. Combined radio-chemotherapy (adjuvant or neoadjuvant) is not indicated outside clinical trials. Surgery is justified in stage N2 disease as good local control can be achieved. T4-N0 disease should be treated surgically with curative intent.
