Endocavitary Right Ventricular Cardiac Metastasis of a Lung Adenocarcinoma Treated by Surgery: A Case Report About a Novel Multimodal Therapeutic Approach.

Introduction: Cardiac metastasis (CM) is a rare lung cancer location. It often remains clinically silent but may cause life-threatening complications. Better survival rates thanks to the immunotherapy revolution and the improving performance of imaging lead to an increasing number of CM diagnosis. Case Presentation: We report a case of a 54-year-old woman who was diagnosed with a stage IIIa non-small cell lung cancer. She developed a right ventricular CM without symptoms during treatment by immunotherapy after concurrent chemoradiotherapy. Cardiac magnetic resonance imaging confirmed the presence of an endocavitary lesion in the right ventricle apex. Complete surgical resection through a right ventriculotomy was performed. Conclusion: The diagnosis of similar cases has become more frequent due to immunotherapy and more advanced imaging technology. Our case report also highlights the fact that CM surgery has to be considered as a successful therapeutic option in those oligo-progression situations. Guidelines on the management and treatment of lung cancer CM are needed as well as larger studies to evaluate the survival benefit from surgical treatment.

Long-term effectiveness and treatment sequences in patients with extensive stage small cell lung cancer receiving atezolizumab plus chemotherapy: Results of the IFCT-1905 CLINATEZO real-world study.

BACKGROUND: Small cell lung cancer (SCLC) has a tendency towards recurrence and limited survival. Standard-of-care in 1st-line is platinum-etoposide chemotherapy plus atezolizumab or durvalumab,based on landmarkclinical trials. METHODS: IFCT-1905 CLINATEZO is a nationwide, non-interventional, retrospectivestudy of patients with extensive-SCLC receivingatezolizumab plus chemotherapy as part of French Early Access Program. Objectives were to analyse effectiveness,safetyand subsequent treatments. RESULTS: The population analyzed included 518 patients who received atezolizumabin 65 participating centers. There were 66.2% male,mean age was 65.7 years; 89.1% had a performance status (PS) 0/1 and 26.6% brain metastases. Almost all(95.9%) were smokers. Fifty-five (10.6%) received at least 1 previous treatment. Median number of atezolizumab injections was 7.0 (range [1.0-48.0]) for a median duration of 4.9 months (95% CI 4.5-5.1). Atezolizumab was continued beyond progression in 122 patients (23.6%) for a median duration of 1.9 months (95% CI: [1.4-2.3]). Best objective response was complete and partialin 19 (3.9%) and 378 (77.1%)patients. Stable diseasewas observed in 50 patients (10.2%). Median follow-up was30.8 months (95% CI: [29.9-31.5]). Median overall survival (OS), 12-, 24-month OS rates were 11.3 months (95% CI: [10.1-12.4]), 46.7% (95% CI [42.3-50.9]) and 21.2% (95% CI [17.7-24.8]). Median real-world progression-free survival, 6-, 12-month rates were 5.2 months (95% CI [5.0-5.4]), 37.5% (95% CI [33.3-41.7]) and 15.2% (95% CI [12.2-18.6]). For patients with PS 0/1, median OS was 12.2 months (95% CI [11.0-13.5]). For patients with previous treatment, median OS was 14.9 months (95% CI [10.1-21.5]). Three-hundred-and-twenty-six patients(66.4%) received subsequent treatment and27 (5.2%) were still underatezolizumabat date of last news. CONCLUSIONS: IFCT-1905 CLINATEZO shows reproductibility, in real-life,ofIMpower-133survival outcomes, possibly attributed to selection of patients fit for this regimen, adoption of pragmatic approaches,including concurrent radiotherapy and treatment beyond progression.

FRESC: French Real world Extensive stage SCLC Cohorts: A retrospective study on patient characteristics and treatment strategy based on KBP-2010.

OBJECTIVES: FRESC reanalyzed extensive-stage small-cell lung cancer (ES-SCLC) patient data from the French KBP-2010 cohort to describe the characteristics and therapeutic management of ES-SCLC and provide real-world estimates of survival. METHODS: A target population of first line (1L) ES-SCLC was identified at initial diagnosis in KBP-2010 (KBP population, N = 796). A KBP-2010 subpopulation was defined as patients who also met the IMpower133 clinicaltrial PS ≤ 1 inclusion criteria (KBP-PS_0/1 population, N = 394). Subgroups were defined according to the 1L ES-SCLC chemotherapy regimens: carboplatin or cisplatin with etoposide (Carb-E or Cisp-E subgroups). RESULTS: The vast majority of KBP populations exhibited stage IV ES-SCLC (84.9%) at initial diagnosis. Median age was 66 years; patients were mostly male and smokers. Patients receiving Cisp + Eto were younger (median age 61 years [55.0-67.0]) and fitter (25.5% had PS ≥ 2) than those receiving Carb + Eto (71 years [62.5-77.5]; 44.1%had PS ≥ 2). Median overall survival (OS) of chemotherapy-treated 1L ES-SCLC patients varied from 7.0 months [95% CI, 6.1; 7.8] in the KBPCarb-Esubgroups to 9.6 months [95% CI, 8.4;10.8] in the KBP Cisp-E subgroup. KBP-PS_0/1 population showed better median OS, especially for the Cisp-E subgroup (10 months [95% CI, 8.7; 11.3]). CONCLUSION: In the KBP-PS_0/1 population, median OS was close to the one that was found in the IMpower133 control arm. Although this needs to be confirmed by further research, it suggests the transposability of the IMpower133 results to real-life conditions.

Orai3-Mediates Cisplatin-Resistance in Non-Small Cell Lung Cancer Cells by Enriching Cancer Stem Cell Population through PI3K/AKT Pathway.

The development of the resistance to platinum salts is a major obstacle in the treatment of non-small cell lung cancer (NSCLC). Among the reasons underlying this resistance is the enrichment of cancer stem cells (CSCs) populations. Several studies have reported the involvement of calcium channels in chemoresistance. The Orai3 channel is overexpressed and constitutes a predictive marker of metastasis in NSCLC tumors. Here, we investigated its role in CSCs populations induced by Cisplatin (CDDP) in two NSCLC cell lines. We found that CDDP treatment increased Orai3 expression, but not Orai1 or STIM1 expression, as well as an enhancement of CSCs markers. Moreover, Orai3 silencing or the reduction of extracellular calcium concentration sensitized the cells to CDDP and led to a reduction in the expression of Nanog and SOX-2. Orai3 contributed to SOCE (Store-operated Calcium entry) in both CDDP-treated and CD133+ subpopulation cells that overexpress Nanog and SOX-2. Interestingly, the ectopic overexpression of Orai3, in the two NSCLC cell lines, lead to an increase of SOCE and expression of CSCs markers. Furthermore, CD133+ cells were unable to overexpress neither Nanog nor SOX-2 when incubated with PI3K inhibitor. Finally, Orai3 silencing reduced Akt phosphorylation. Our work reveals a link between Orai3, CSCs and resistance to CDDP in NSCLC cells.

Primary meningococcal arthritis in a COVID-19 18-year-old man: a case report and review of the literature.

BACKGROUND: SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection is associated with various complications. PMA (primary meningococcal arthritis) is a rare meningococcus-associated disease causing arthritis of the knee usually, without any signs of invasive meningococcal disease. No case of PMA in a COVID-19 (coronavirus disease, 2019) patient has yet been described. PMA mainly strikes young adults. PMA is not associated with any immunocompromising condition. It has a better outcome than usual septic arthritis CASE PRESENTATION: Herein, we report an 18-year-old man diagnosed with COVID-19, later admitted with persistent fever, right knee arthralgia and maculopapular rash. Due to family history, psoriasis and Henoch-Schönlein purpura were hypothesized and ruled out. Finally, synovial fluid culture confirmed Neisseria meningitidis serogroup B arthritis without any other symptoms of invasive meningococcal disease. Healing was achieved quickly with surgery and antibiotics. We concluded in a PMA. CONCLUSION: We describe here the first primary meningococcal arthritis in a COVID-19 patient and we hope to shine a light on this rare but serious complication.

Weekly paclitaxel plus bevacizumab versus docetaxel as second- or third-line treatment in advanced non-squamous non-small-cell lung cancer: Results of the IFCT-1103 ULTIMATE study.

PURPOSE: Second-line chemotherapy regimens have demonstrated poor benefit after failure of platinum-based chemotherapy in advanced non-squamous non-small-cell lung cancer (nsNSCLC). METHODS: In this multicentre, open-label phase III trial, patients with advanced nsNSCLC treated with one or two prior lines, including one platinum-based doublet, were centrally randomised to receive 90 mg/m2 of paclitaxel (D1, D8, D15) plus 10 mg/kg of bevacizumab (D1, D15) every 28 days or docetaxel (75 mg/m2) every 21 days; crossover was allowed after disease progression. Primary end-point was progression-free survival (PFS). ClinicalTrials.gov registration number: NCT01763671. RESULTS: One hundred sixty six patients were randomised (paclitaxel plus bevacizumab: 111, docetaxel: 55). The median PFS was longer in patients receiving paclitaxel plus bevacizumab than in patients receveing docetaxel [5·4 months versus 3·9 months, adjusted hazard ratio (HR) 0·61 (95% confidence interval [CI]: 0·44-0·86); p = 0·005]. Objective response rates (ORRs) were 22·5% (95% CI: 14·8-30·3) and 5·5% (95% CI: 0·0-11·5) (p = 0·006), respectively. Median overall survivals were similar (adjusted HR 1·17; p = 0·50). Crossover occurred in 21 of 55 (38·2%) docetaxel-treated patients. Grade III-IV adverse events (AEs) were reported in 45·9% and 54·5% of patients treated with paclitaxel and bevacizumab or docetaxel, respectively (p = NS), including neutropenia (19·3% versus 45·4%), neuropathy (8·3% versus 0·0%) and hypertension (7·3% versus 0·0%). Three patients died due to treatment-related AEs (1·8% in each group). CONCLUSION: Weekly paclitaxel plus bevacizumab as second- or third-line improves PFS and ORR compared with docetaxel in patients with nsNSCLC, with an acceptable safety profile. These results place weekly paclitaxel plus bevacizumab as a valid option in this population. CLINICAL TRIALS REGISTRATION NUMBER: ClinicalTrials.gov Identifier: NCT01763671.

Increased frequency of anti-Ma2 encephalitis associated with immune checkpoint inhibitors.

OBJECTIVE: To report the induction of anti-Ma2 antibody-associated paraneoplastic neurologic syndrome (Ma2-PNS) in 6 patients after treatment with immune checkpoint inhibitors (ICIs). We also analyzed (1) patient clinical features compared with a cohort of 44 patients who developed Ma2-PNS without receiving ICI treatment and (2) the frequency of neuronal antibody detection before and after ICI implementation. METHODS: Retrospective nationwide study of all patients with Ma2-PNS developed during ICI treatment between 2017 and 2018. RESULTS: Our series of patients included 5 men and 1 woman (median age, 63 years). The patients were receiving nivolumab (n = 3), pembrolizumab (n = 2), or a combination of nivolumab and ipilimumab (n = 1) for treatment of neoplasms that included lung (n = 4) and kidney (n = 1) cancers and pleural mesothelioma (n = 1). Clinical syndromes comprised a combination of limbic encephalitis and diencephalitis (n = 3), isolated limbic encephalitis (n = 2), and a syndrome characterized by ophthalmoplegia and head drop (n = 1). No significant clinical difference was observed between our 6 patients and the overall cohort of Ma2-PNS cases. Post-ICI Ma2-PNS accounted for 35% of the total 17 Ma2-PNS diagnosed in our center over the 2017-2018 biennium. Eight cases had been detected in the preceding biennium 2015-2016, corresponding to a 112% increase of Ma2-PNS frequency since the implementation of ICIs in France. Despite ICI withdrawal and immunotherapy, 4/6 patients died, and the remaining 2 showed a moderate to severe disability. CONCLUSIONS: We show a clear association between ICI use and increased diagnosis of Ma2-PNS. Physicians need to be aware that ICIs can trigger Ma2-PNS because clinical presentation can be challenging.

Circulating free tumor-derived DNA to detect EGFR mutations in patients with advanced NSCLC: French subset analysis of the ASSESS study.

BACKGROUND: The non-interventional ASSESS study (NCT01785888) evaluated the utility of circulating free tumor-derived DNA (ctDNA) from plasma for epidermal growth factor receptor (EGFR) mutation testing in patients with advanced non-small-cell lung cancer (NSCLC), in a real-world setting across 56 centers in Europe and Japan. The high mutation status concordance between 1162 matched tissue/cytology and plasma samples (89%, sensitivity =46%, specificity =97%) suggested that ctDNA is a feasible sample for EGFR mutation analysis. We report data for the French subset of patients (pre-planned analysis). METHODS: Eligible patients (stage IIIA/B/IV locally advanced/metastatic treatment-naive advanced NSCLC) provided diagnostic tissue/cytology and plasma samples. DNA extracted from tissue/cytology samples was subjected to EGFR mutation testing as per local practice; a designated laboratory performed ctDNA extraction/mutation testing of plasma samples. The primary outcome was EGFR mutation status concordance between matched tumor and plasma samples. RESULTS: Of the 1,311 patients enrolled in the ASSESS trial, 145 were recruited from 9 centers in France. Tumor samples from 130 patients were collected and 126 were evaluable for EGFR mutation analysis. Activating EGFR mutations were identified in 13 of the 126 patient tumor samples (EGFR mutation frequency 10.3%). For plasma testing, 10 of the 145 samples tested were positive for EGFR mutations (EGFR mutation frequency 6.9%). EGFR mutation rate was significantly higher in never- versus ever-smokers (stepwise logistic regression: tumor, P<0.0001; plasma, P=0.0008). Mutation status concordance between 126 matched patient samples was 96.0% [121/126; 95% confidence intervals (CI), 91.0-98.7]. Of the 113 EGFR mutation-negative patient tissue samples, one tested plasma-positive; reanalysis of plasma via two different techniques confirmed the presence of a L858R mutation, indicating a tissue false-negative result. Based on these data, sensitivity of plasma testing was 64.3% (9/14; 95% CI, 35.1-87.2%) and its specificity was 100.0% (112/112; 95% CI, 96.8-100.0%). CONCLUSIONS: Data confirm ctDNA as an alternative sample for EGFR mutation analysis in patients with advanced NSCLC.

Evidence of slight improvement in five-year survival in non-small-cell lung cancer over the last 10 years: Results of the French KBP-CPHG real-world studies.

BACKGROUND: Although improved during the last decades, the prognosis of lung cancer is poor. In 2000, the French College of general hospital respiratory physicians, conducted KBP-2000-CPHG, a prospective multicenter epidemiological study including all volunteer adult patients diagnosed for primary lung cancer; with the five-year survival as primary endpoint. The primary objective of KBP-2010-CPHG was to compare overall five-year survival data with KBP-2000-CPHG ones. MATERIAL AND METHODS: All consecutive patients≥18 years of age with primary lung cancer diagnosed between 1st January and 31st December 2010 were included. The KBP-2010-CPHG protocol was approved by the advisory committee on research information processing in the health field (CCTIRS) on November 19, 2009. RESULTS: Respectively, 5667 and 7051 patients were included in KBP-2000-CPHG and KBP-2010-CPHG. Five-year survival was improved: 12.7% [11.9%-13.5%] in 2010 versus 10.0% [9.2%-10.9%] in 2000 (P<0.001). Non-small-cell lung cancer showed improvement (13.8% [13.0%-14.8%] in 2010 versus 11.4% [10.5%-12.4%] in 2000; P<0.001); but not small-cell lung cancer (5.7% [4.4%-7.4%] in 2010 versus 3.3% [2.3%-4.7%] in 2000; P=0.56). The KBP-2010-CPHG study showed an overall 6% reduction in risk of death (HR=0.94 [0.89-0.98]; P=0.004). CONCLUSIONS: Survival of patients with lung cancer improved over a 10-year period. This improvement was slight and limited to non-small-cell lung cancer, possibly partly because of 2010 advances in diagnosis and targeted therapy.

Clinical efficacy and cost-effectiveness of endobronchial ultrasound-guided transbronchial needle aspiration for preoperative staging of non-small-cell lung cancer: Results of a French prospective multicenter trial (EVIEPEB).

This two-step study evaluated the cost-effectiveness of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for presurgery staging of non-small cell lung cancer (NSCLC) in France (EVIEPEB; ClinicalTrial.gov identifier NCT00960271). Step 1 consisted of a high-benchmark EBUS-TBNA-training program in participating hospital centers. Step 2 was a prospective, national, multicenter study on patients with confirmed or suspected NSCLC and an indication for mediastinal staging with at least one lymph node > 1 cm in diameter. Patients with negative or uninformative EBUS-TBNA and positron-emission tomography-positive or -negative nodes, respectively, underwent either mediastinoscopy or surgery. Direct costs related to final diagnosis of node status were prospectively recorded. Sixteen of 22 participating centers were certified by the EBUS-TBNA-training program and enrolled 163 patients in Step 2. EBUS-TBNA was informative for 149 (91%) patients (75 malignant, 74 non-malignant) and uninformative for 14 (9%). Mediastinoscopy was avoided for 80% of the patients. With a 52% malignant-node rate, EBUS-TBNA positive- and negative-predictive values, respectively, were 100% and 90%. EBUS-TBNA was cost-effective, with expected savings of €1,450 per patient, and would have remained cost-effective even if all EBUS-TBNAs had been performed under general anesthesia or the cost of the procedure had been 30% higher (expected cost-saving of €994 and €1,427 per patient, respectively). After EBUS-TBNA training and certification of participating centers, the results of this prospective multicenter study confirmed EBUS-TBNA cost-effectiveness for NSCLC staging.

Symptom and Quality of Life Improvement in LUX-Lung 8, an Open-Label Phase III Study of Second-Line Afatinib Versus Erlotinib in Patients With Advanced Squamous Cell Carcinoma of the Lung After First-Line Platinum-Based Chemotherapy.

INTRODUCTION: In the phase III LUX-Lung 8 trial, afatinib significantly improved progression-free survival (PFS) and overall survival (OS) versus erlotinib in patients with squamous cell carcinoma (SCC) of the lung progressing during or after platinum-based chemotherapy. Patient-reported outcomes (PROs) and health-related quality of life (QoL) in these patients are presented. PATIENTS AND METHODS: Patients (n = 795) were randomized 1:1 to oral afatinib (40 mg/d) or erlotinib (150 mg/d). PROs were collected (baseline, every 28 days until progression, 28 days after discontinuation) using the European Organization for Research and Treatment of Cancer QoL questionnaire and lung cancer-specific module. The percentage of patients improved during therapy, time to deterioration (TTD), and changes over time were analyzed for prespecified lung cancer-related symptoms and global health status (GHS)/QoL. RESULTS: Questionnaire compliance was 77.3% to 99.0% and 68.7% to 99.0% with afatinib and erlotinib, respectively. Significantly more patients who received afatinib versus erlotinib experienced improved scores for GHS/QoL (36% vs. 28%; P = .041) and cough (43% vs. 35%; P = .029). Afatinib significantly delayed TTD in dyspnea (P = .008) versus erlotinib, but not cough (P = .256) or pain (P = .869). Changes in mean scores favored afatinib for cough (P = .0022), dyspnea (P = .0007), pain (P = .0224), GHS/QoL (P = .0320), and all functional scales. Differences in adverse events between afatinib and erlotinib, specifically diarrhea, did not affect GHS/QoL. CONCLUSION: In patients with SCC of the lung, second-line afatinib was associated with improved prespecified disease-related symptoms and GHS/QoL versus erlotinib, complementing PFS and OS benefits with afatinib.

New insights into stage and prognosis in small cell lung cancer: an analysis of 968 cases.

BACKGROUND: The French College of General Hospital Respiratory Physicians conducted two studies that consecutively included all patients followed in participating general hospitals for primary small cell (SCLC) or non-small cell (NSCLC) lung cancer diagnosed in 2000 and 2010. These studies allow descriptive statistics and outcome assessment for SCLC and NSCLC separately and comparison over a 10-year period. METHODS: A standardised form was completed for each patient at inclusion. Then, vital status was collected. RESULTS: In 2000 and 2010, 948 (15.5% female) and 968 (23.3%) SCLC patients, mainly heavy active- or former-smoker seniors, participated in these studies. One-year survival rate was 35.8% for SCLC vs. 44.8% for NSCLC in 2010 and 33.1% for SCLC in 2000. In 2010, in reference to stage 0-IIB (4.1% of SCLCs), the hazard ratio was 0.92 [95% confidence interval (CI): 0.6-1.5; P=0.76], 1.8 (95% CI: 1.1-2.8; P=0.019), and 3.4 (95% CI: 2.2-5.3; P<0.001) for stage IIIA (10.2%), IIIB (14.5%), and IV (71.2%). Positron emission tomography (PET)-scan use, which has increased in 10 years, was frequent in patients with limited disease. CONCLUSIONS: One-year survival in SCLC patients was poor in 2010 and dependent of SCLC stage. TNM classification reintroduction and new diagnostic techniques (e.g., PET-scan) should allow lung oncologists to tailor treatment based on disease stage at diagnosis.

Major changes in lung cancer over the last ten years in France: the KBP-CPHG studies.

The incidence of lung cancer has dramatically increased in ten years, being now the most commonly diagnosed cancer in males and the fourth most commonly diagnosed cancer in females. Considering social and scientific evolution, the aim of the present study conducted by the French College of General Hospital Respiratory Physicians (CPHG) was to compare patient and lung cancer characteristics at a ten-year interval. Two epidemiological studies, KBP-2000-CPHG and KBP-2010-CPHG, were conducted at a ten-year interval. These prospective multicentre studies included all patients ≥ 18 years of age with primary lung cancer diagnosed between 1st January and 31st December 2000 or 2010, and managed in the respiratory departments of one of the participating general hospitals. A standardised form was completed for each patient. A steering committee checked recruitment exhaustiveness. Respectively, in 2000 and 2010, 137 and 104 centres included 5667 and 7051 patients. Compared to 2000, patients in 2010 were significantly older (65.5 ± 11.3 vs. 64.3 ± 11.5 years, p < 0.0001), more frequently women (24.3% vs. 16.0%, p < 0.0001) and never-smokers (10.9% vs. 7.2%, p < 0.0001). In 2010, adenocarcinoma was the most common tumour (45.4%, vs. 29.0% in 2000, p < 0.0001). The adenocarcinoma rate increased irrespective of sex, age, or smoking status (relative risk [RR] before and after adjustment, RR = 2.07 [1.92-2.24], p < 0.0001 and 2.06 [1.90-2.23], p < 0.0001). In ten years, lung cancer characteristics have therefore changed: more women, more never-smokers, and more adenocarcinomas. The particular high increase in adenocarcinoma rate deserves further analysis.

Bacterial infection profiles in lung cancer patients with febrile neutropenia.

BACKGROUND: The chemotherapy used to treat lung cancer causes febrile neutropenia in 10 to 40% of patients. Although most episodes are of undetermined origin, an infectious etiology can be suspected in 30% of cases. In view of the scarcity of data on lung cancer patients with febrile neutropenia, we performed a retrospective study of the microbiological characteristics of cases recorded in three medical centers in the Picardy region of northern France. METHODS: We analyzed the medical records of lung cancer patients with neutropenia (neutrophil count < 500/mm(3)) and fever (temperature > 38.3°C). RESULTS: The study included 87 lung cancer patients with febrile neutropenia (mean age: 64.2). Two thirds of the patients had metastases and half had poor performance status. Thirty-three of the 87 cases were microbiologically documented. Gram-negative bacteria (mainly enterobacteriaceae from the urinary and digestive tracts) were identified in 59% of these cases. Staphylococcus species (mainly S. aureus) accounted for a high proportion of the identified Gram-positive bacteria. Bacteremia accounted for 60% of the microbiologically documented cases of fever. 23% of the blood cultures were positive. 14% of the infections were probably hospital-acquired and 14% were caused by multidrug-resistant strains. The overall mortality rate at day 30 was 33% and the infection-related mortality rate was 16.1%. Treatment with antibiotics was successful in 82.8% of cases. In a multivariate analysis, predictive factors for treatment failure were age >60 and thrombocytopenia < 20000/mm(3). CONCLUSION: Gram-negative species were the most frequently identified bacteria in lung cancer patients with febrile neutropenia. Despite the success of antibiotic treatment and a low-risk neutropenic patient group, mortality is high in this particular population.

Aortic endostent followed by extended pneumonectomy for T4 lung cancer.

Pulmonary and aortic en bloc resection may be performed with cardiopulmonary bypass support, but is associated with high surgical morbidity and mortality. A 59-year-old man with left lower lobe cancer invading the aorta was considered to be unsuitable for such an extended operation because of previous myocardial infarction, coronary bypass grafts, and subsequent multiple coronary artery stenting. Pneumonectomy with en bloc resection of aortic adventitia and media was accomplished after thoracic aorta endovascular stent graft placement. The aortic defect was reinforced with an extrathoracic muscle flap. The postoperative course was uneventful, and the patient was faring well at the 23-month follow-up. An endovascular stent may be an alternative in selected patients with aortic involvement, avoiding the need for cardiopulmonary bypass.

Bronchial fistula associated with sunitinib in a patient previously treated with radiation therapy.

OBJECTIVE: To report a case of bronchial fistula associated with sunitinib in a patient previously treated with radiation therapy. CASE SUMMARY: A 40-year-old man with renal cell cancer diagnosed in 2005 and initially treated by radical nephrectomy presented in March 2007 with a recurrence with cerebral, mediastinal, and lung metastases. A thoracic computed tomography (CT) scan showed a subcarinal tumor obstructing the bronchus intermedius. The patient was initially treated with cerebral and thoracic radiotherapy and then with sunitinib 50 mg/day (4 weeks on, 2 weeks off). Two months after the beginning of treatment, a CT scan revealed a dramatic reduction in the size of the tumor, associated with a bronchial fistula. This was confirmed by flexible bronchoscopy, which showed complete necrosis of the tumor and a large perforation of the bronchus intermedius. Sunitinib was immediately withdrawn and antibiotic prophylaxis was instituted. It was not possible to place an endobronchial stent. Two weeks later, flexible bronchoscopy revealed the reappearance of a yellowish mass protruding into the bronchus intermedius (40% obstruction). A few months later, the obstruction of the bronchus intermedius progressed to 90% and was associated with a contralateral obstruction of the left mainstem bronchus (20%). A rigid bronchoscopy was then performed to clear the obstruction and an endobronchial stent was placed, with satisfactory initial results. In February 2008, the patient presented with new bronchial obstruction under the endobronchial stent but refused a rigid bronchoscopy and died in March 2008. DISCUSSION: Sunitinib, a multitarget tyrosine kinase inhibitor with antiangiogenic and antitumoral activities, has been approved for the treatment of advanced renal cell carcinoma. This treatment is generally well tolerated. Serious complications may occur, however. According to the Naranjo probability scale, the bronchial fistula was possibly related to sunitinib treatment. CONCLUSIONS: This is a rare case of a bronchial perforation leading to a fistula associated with sunitinib treatment after mediastinal radiation therapy. Clinicians may consider strict follow-up of patients with proximal lung metastases treated with sunitinib (CT scan and, if appropriate, placement of an endobronchial stent).

Paecilomyces variotii fungemia in a patient with multiple myeloma: case report and literature review.

Infectious complications are common in patient with multiple myeloma. However, Paecilomyces variotii, a common saprophytic fungus, rarely causes human infection. We report the first case of P. variotii fungemia in this illness with good response with adapted anti-mycotic treatment.

[Lemierre syndrome: unusual, but still possible]. / Le syndrome de Lemierre: exceptionnel, mais encore possible.

Lemierre syndrome is a rare disease, which was life-threatening before the antibiotics era. We report here two cases with favorable outcome. Clinical features are stereotypic: tonsillis, cervical pain revealing deep vein thrombosis, and pulmonary septic metastasis. The most frequent causal germ on blood cultures is Fusobacterium necrophorum but other anaerobial bacteries can be found. Cervical Doppler-ultrasonography, and thoracic tomodensitometry are useful. Medical treatment is antibiotic therapy and anticoagulation.
