RESUMO

OBJECTIVES: According to a nation-based study, we intend to report the data of the patients operated on for lung cancer invading the chest wall, taking into consideration the completion of induction chemotherapy (Ind_CT), induction radiochemotherapy (Ind_RCT) or no induction therapy (0_Ind). MATERIALS AND METHODS: All patients with a primary lung cancer invading the chest wall who underwent radical resection from 2004 to 2019 were included. Superior sulcus tumors were excluded. RESULTS: Overall, 688 patients were included: 522 operated without induction therapy, 101 with Ind_CT and 65 with Ind_RCT. Postoperative 90-day mortality was 10.7% in the 0_Ind group, 5.0% in the Ind_CT group, 7.7% in the Ind_RCT group (p = 0.17). Incomplete resection rate was 14.0% in the 0_Ind group, 6.9% in the Ind_CT group, 6.2% in the Ind_RCT group (p = 0.04). In the 0_Ind group, 70% of the patients received adjuvant therapies. Overall survival (OS) analysis disclosed the best long-term outcomes in the Ind_RCT group (5-year OS probability: 56.5% versus 40.0% and 40.5% for 0_Ind and Ind_CT groups, respectively; p = 0.035). At multivariable analysis, Ind_RCT (HR = 0.571; p = 0.008), age > 60 years old (HR = 1,373; p = 0.005), male sex (HR = 1.710; p < 0.001), pneumonectomy (HR = 1.368; p = 0.025), pN2 status (HR = 1.981; p < 0.001), ≥3 resected ribs (HR = 1.329; p = 0.019), incomplete resection (HR = 2.284; p < 0.001) and lack of adjuvant therapy (HR = 1.959; p < 0.001) were associated with OS. Ind_CT was not associated with survival (HR = 0.848; p = 0.257). CONCLUSION: Induction chemoradiation therapy seems to improve survival. Therefore, the present results should be confirmed by a prospective randomized trial testing the benefit of induction radiochemotherapy for NSCLC invading the chest wall.

RESUMO

INTRODUCTION: Stage III NSCLC comprises a heterogeneous population. Different treatment strategies are available, including surgery, radiotherapy, and chemotherapy. The PACIFIC trial results represented a significant change and improvement in the therapeutic strategy for these patients. We aimed to compare the different treatment strategies employed in Stage III NSCLC patients within our institution. METHODS: All Stage III NSCLC patients discussed during the weekly thoracic oncology multidisciplinary team meetings at the University hospital Grenoble Alpes (France) between January 2010 and January 2017 were included. Patients' overall survival (OS) according to treatment strategies along with their respective changes were compared. RESULTS: Overall, 476 patients were identified. Among patients initially scheduled to receive neoadjuvant chemotherapy followed by surgery (n = 60), only 37 (62%) actually underwent surgery. Median OS of the cohort was 21.3 months [IQR 25%-75%: 9.6-48.3]. Patients who received neoadjuvant chemotherapy followed by surgery displayed better survival than those treated by CT-RT: 53.2 months [IQR 25%-75%: 16.1-87.3] versus 23.9 [IQR 25%-75%, 13.3-48.1]. Survival was slightly superior for patients treated by upfront CT-RT than for those planned for neoadjuvant chemotherapy followed by surgery who eventually converted to CT-RT (concurrent or sequential): 23.9 months [IQR 25%-75%: 13.3-48.1] versus 20.4 [IQR 25%-75%:10.8-36], respectively. CONCLUSION: While patients who underwent neoadjuvant chemotherapy followed by surgery displayed a better survival than those treated using CT-RT, switch from surgery to CT-RT actually shortened survival. These results stress the relevance of the tumor board in deciding which is the best therapeutic strategy for Stage III disease patients.

RESUMO

OBJECTIVES: To report our experience on the management of superior vena cava graft infection. METHODS: Between 2001 and 2018, patients with superior vena cava synthetic graft or patch reconstruction after resection of intrathoracic tumours or benign disease were selected retrospectively from the French EPITHOR database and participating thoracic centres. Our study population includes patients with superior vena cava graft infection, defined according to the MAGIC consensus. Superior vena cava synthetic grafts in an empyema or mediastinitis were considered as infected. RESULTS: Of 111 eligible patients, superior vena cava graft infection occurred in 12 (11.9%) patients with a polytetrafluoroethylene graft secondary to contiguous contamination. Management consisted of either conservative treatment with chest tube drainage and antibiotics (n = 3) or a surgical graft-sparing strategy (n = 9). Recurrence of infection appears in 6 patients. Graft removal was performed in 2 patients among the 5 reoperated patients. The operative mortality rate was 25%. CONCLUSIONS: Superior vena cava graft infection may develop as a surgical site infection secondary to early mediastinitis or empyema. Graft removal is not always mandatory but should be considered in late or recurrent graft infection or in infections caused by aggressive microorganisms (virulent or multidrug resistant bacteria or fungi).

RESUMO

Sarcomas are rare tumours that represent less than 1% of all malignant tumours in adults. Liposarcomas are among the most common malignant mesenchymal tumours. They are preferentially located in the limbs and the retroperitoneum. Liposarcomas primarily arising in the digestive tract are exceptional with a few cases reported in the literature. Their clinical presentation is variable and the symptoms are not specific. Anatomopathological examination remains the gold standard for the diagnosis and the classification of these tumours, which are divided into 5 histological types according to the 5th edition of the WHO classification of soft tissue tumours. We report two observations of unusual digestive liposarcomas, located in the oesophagus and the colon, emphasizing the variability of the diagnostic challenges, depending on the clinical presentation, the histological type and the analysed material.

RESUMO

INTRODUCTION: Surgical management of Diaphragmatic and thoracic endometriosis (DTE) is still controversial, a thoracic or an abdominal approach can be proposed. METHODS: We conducted a multicentric retrospective study in 8 thoracic, gynecology or digestive surgery units in 5 French university hospitals. The main objective was to review the current management of DTE. RESULTS: 50 patients operated for DTE from 2010 to 2017 were included: 26 with a thoracic approach and 24 with an abdominal approach. Preoperative pelvic endometriosis (PE) concerned 25 patients. In 38 patients, DTE diagnosis was made on clinical symptoms (pneumothorax (n = 19), chronic or catamenial chest pain (n = 18) or hemopneumothorax (n = 1)). Median time from onset of symptoms to diagnosis was 47 months (0-212). PE surgery concurrently occurred in 22 patients. We report diaphragmatic nodules, pleuropulmonary nodules and diaphragmatic perforations in 42, 5 and 22 women respectively. Lesions were right-sided in 45 patients. Nodules were destructed in 12 cases and resected in 38 cases. When a diaphragmatic reconstruction was needed (n = 31), a simple suture was performed in 26 patients, while 5 patients needed a mesh repair. Pleural symphysis was performed for all patients who received a thoracic approach. DTE resection was considered complete in 46 patients. Three patients had severe 30-days complications of DTE surgery. Median follow-up was 20 months (range 1-69). Recurrence occurred in 10 patients. CONCLUSION: The results emphasize the importance of systematically looking for chest pain in patients suffering from PE and underline the lack of a standardized procedure and treatment in DTE.

RESUMO

OBJECTIVES: Home-based rehabilitation programmes (H-RPs) could facilitate the implementation of pulmonary rehabilitation prior to resection for non-small cell lung cancer (NSCLC), but their feasibility has not been evaluated. The aim of this study was to identify determinants of non-completion of an H-RP and the factors associated with medical events occurring 30 days after hospital discharge. DESIGN: A prospective observational study. INTERVENTION: All patients with confirmed or suspected NSCLC were enrolled in a four-component H-RP prior to surgery: (i) smoking cessation, (ii) nutritional support, (iii) physiotherapy (at least one session/week) and (iv) home cycle-ergometry (at least three times/week). OUTCOMES: The H-RP was defined as 'completed' if the four components were performed before surgery. RESULTS: Out of 50 patients included, 42 underwent surgery (80% men; median age: 69 (IQR 25%-75%; 60-74) years; 64% Chronic Obstructive Pulmonary Disease (COPD); 29% type 2 diabetes). Twenty patients (48%) completed 100% of the programme. The median (IQR) duration of the H-RP was 32 (19; 46) days. Multivariate analysis showed polypharmacy (n=24) OR=12.2 (95% CI 2.0 to 74.2), living alone (n=8) (single vs couple) OR=21.5 (95% CI 1.4 to >100) and a long delay before starting the H-RP (n=18) OR=6.24 (95% CI 1.1 to 36.6) were independently associated with a risk of non-completion. In univariate analyses, factors associated with medical events at 30 days were H-RP non-completion, diabetes, polypharmacy, social precariousness and female sex. CONCLUSION: Facing multiple comorbidities, living alone and a long delay before starting the rehabilitation increase the risk of not completing preoperative H-RP. TRIAL REGISTRATION NUMBER: NCT03530059.

RESUMO

We describe a patient with polytrauma that included anterior chest flail caused by a fall while climbing. As the situation was similar to a pectus excavatum, we attempted to stabilize the depressed chest wall by using a vacuum bell. Deep breath, peak flow, and pectus index were increased when the patient used the vacuum bell. Conservative treatment with a vacuum bell during the day and continuous positive airway pressure during the night was undertaken for 6 weeks. This report documents stabilization of an anterior flail chest using a vacuum bell.

RESUMO

The esophagus traverses three body compartments (neck, thorax, and abdomen) and is surrounded at each level by vital organs. Injuries to the esophagus may be classified as foreign body ingestion, caustic ingestion, esophageal perforation, and esophageal trauma. These lesions can be life-threatening either by digestive contamination of surrounding structures in case of esophageal wall breach or concomitant damage of surrounding organs. Early diagnosis and timely therapeutic intervention are the keys of successful management.

RESUMO

BACKGROUND: Stage IV non-small cell lung cancer (NSCLC) is considered incurable; however, some patients with only few metastases may benefit from treatment with a curative intent. We aimed to identify the prognostic factors for stage IV NSCLC with synchronous solitary M1. METHODS: A database constructed from our weekly multidisciplinary thoracic oncology meetings was retrospectively screened from 1993 to 2012. Consecutive patients with NSCLC stages I to IV were included. RESULTS: Of the 6,760 patients found, 4,832 patients were studied. Among the 1,592 patients (33%) with stage IV NSCLC, 109 (7%) had a synchronous solitary M1. Metastasis involved the brain in 64% of patients. Median overall survival was significantly longer in synchronous solitary M1 than in other stage IV (18.9 months, interquartile range [IQR]: 9.9 to 34.6 months versus 6.1 months, IQR: 2.3 to 13.7 months], respectively, p < 10-4). Among patients with synchronous solitary M1, 90 (83%) received a local treatment with curative intent at the primary and metastatic sites. Factors independently associated with survival were age older than 63 years (hazard ratio [HR] 1.63, 95% confidence interval [CI]: 1.01 to 2.63), Performance status of 3 or 4 (HR 7.91, 95% CI: 2.23 to 28.03), use of chemotherapy (HR 0.38, 95% CI: 0.23 to 0.64), and operation conducted at both sites (HR 0.35, 95% CI: 0.19 to 0.65). CONCLUSIONS: Synchronous solitary M1 treated with chemotherapy and operation at both sites resulted in better survival. Survival of NSCLC with synchronous solitary M1 was more similar to stage III than other stage IV NSCLCs. The eighth TNM classification takes this into account by distinguishing between stages M1b and M1c.

RESUMO

PURPOSE: Surgical esophagectomy is the gold standard treatment of early-stage esophageal cancer. The procedure is complicated with significant morbidity; the most severe complication being the anastomotic leakage. Anastomotic fistulas are reported in 5-25% of cases and are mainly due to gastric transplant ischemia. Here, we report our experience of ischemic pre-conditioning using preoperative arterial embolization (PreopAE) before esophagectomy. MATERIALS AND METHODS: The medical records of all patients who underwent oncologic esophagectomy from 2008 to 2015 were retrospectively reviewed. Patients were divided into two groups: patients who received PreopAE, and a control group of patients who did not benefit from ischemic pre-conditioning. The target arteries selected for PreopAE were the splenic artery, left gastric artery, and right gastric artery. Evaluation of the results was based on anastomotic leakage, postoperative mortality, technical success of PreopAE, and complications related to the embolization procedure. RESULTS: Forty-six patients underwent oncologic esophagectomy with PreopAE and 13 patients did not receive ischemic conditioning before surgery. Thirty-eight PreopAE were successfully performed (83%), but right gastric artery embolization failed for 8 patients. Anastomotic leakage occurred in 6 PreopAE patients (13%) and in 6 patients (46%) in the control group (p = 0.02). The mortality rate was 2% in the PreopAE group and 23% in the control group (p = 0.03). Eighteen patients suffered from partial splenic infarction after PreopAE, all treated conservatively. CONCLUSION: Preoperative ischemic conditioning by arterial embolization before oncologic esophagectomy seems to be effective in preventing anastomotic leakage.

RESUMO

OBJECTIVE: The objective of this study was to determine the efficacy of alginate staple-line reinforcement of fissure openings as compared with stapling alone, with or without tissue sealant or glue, in reducing the incidence and duration of air leakage after pulmonary lobectomy for malignancy. SUMMARY BACKGROUND DATA: No randomized trial evaluating alginate staple-line reinforcement has been performed to date. METHODS: The Staple-line Reinforcement for Prevention of Pulmonary Air Leakage study was a multicenter randomized trial, with blinded evaluation of endpoints. Patients over 18 years of age scheduled for elective open lobectomy or bilobectomy for malignancy were eligible for enrollment. At thoracotomy, patients were deemed ineligible if an unanticipated pneumonectomy was indicated, or if air leakage occurred after the liberation of pleural adhesions. Otherwise, if the fissure was incomplete or the lung had an emphysematous appearance, patients were randomized to either standard management or interventional procedure consisting of fissure opening with linear cutting staplers buttressed with paired alginate sleeves (FOREseal). The number of eligible patients necessary in each randomization arm was estimated to be 190, and an outcomes analysis was performed on an intention-to-treat basis. RESULTS: Of the 611 patients consented to study enrollment, 380 met the inclusion criteria and were randomized. Based on an intention-to-treat analysis, the primary endpoint of air leak duration was not different between the 2 groups: 1 day (range: 0-2 d) in the FOREseal group and 1 day (range: 0-3 d) in the control group (P = 0.8357). In addition, the 2 groups were similar in terms of the proportion of patients presenting with prolonged air leakage (7.8% in the FOREseal group vs 11.3% in the control group, P = 0.264) and the average duration of chest drainage (P = 0.107). Procedure costs were comparable for both groups. CONCLUSIONS: FOREseal did not demonstrate a significant advantage over standard treatment alone.

RESUMO

We report the first case of endovascular covered stent implantation for the treatment of a large pulmonary artery pseudoaneurysm (PAPA) following a right thoracic gunshot wound. After resuscitation and hemodynamic stabilization, a CT angiography was performed to analyze the neck size of the PAPA and its position relative to the branches of the parent artery. Covered stent implantation with additional coil embolization was successfully performed. At the 4-year follow-up, the stents remained patent and there was neither pseudoaneurysm recurrence nor treatment-related complication.

RESUMO

We present a case of a giant (13-cm length) purely polypoid esophageal leiomyoma without any intramural development. This form of leiomyoma is rare and develops due to proliferation originating from the muscularis mucosae, although the intramural type originates in the muscularis propria. This should not be confused with giant fibrovascular polyps, which are postulated to arise at the pharyngoesophageal junction when a flap of mobile, redundant submucosa prolapses distally and may cause asphyxia when protruding into the mouth. Our case was successfully removed by a right thoracotomy.

RESUMO

OBJECTIVES: The high mortality rate observed on the regular waiting list (RWL) before lung transplantation (LTx) prompted the French organ transplantation authorities to set up in 2007 a dedicated graft allocation strategy, the so-called 'high-emergency waiting list' (HEWL), for patients with an abrupt worsening of their respiratory function. This study reports on the early results of this new allocation system. METHODS: Among 11 active French LTx programmes, 7 were able to provide full outcome data by 31 December 2011. The medical records of 101 patients who were listed on the HEWL from July 2007 to December 2011 were reviewed for an intention-to-treat analysis. RESULTS: Ninety-five patients received LTx within a median waiting time on the HEWL of 4 days (range 1-26), and 6 died before transplantation. Conditions were cystic fibrosis (65.2%), pulmonary fibrosis (24.8%), emphysema (5%) and miscellaneous (5%). The median age of the recipient was 30 years (range 16-66). Patients listed on the HEWL came from the RWL in 48.5% of the cases and were new patients in 51.5%. Forty-nine were placed under invasive ventilation and, in 26 cases, extracorporeal membrane oxygenation (ECMO) prior to transplantation was necessary as a complementary treatment. ECMO for non-intubated patients was performed in 6 cases. Eighty-one bilateral and 14 single LTx were performed, with an overall in-hospital mortality rate of 29.4%. One- and 3-year survival rates were 67.5 and 59%, respectively. Multivariate analysis shows that the use of ECMO prior to transplantation was the sole independent mortality risk factor (hazard ratio = 2.77 [95% CI 1.26-6.11]). CONCLUSIONS: The new allocation system aimed at lowering mortality on the RWL, but also offered an access to LTx for new patients with end-stage respiratory failure. The HEWL increased the likelihood of mortality after LTx, but permitted acceptable mid-term survival rates. The high mortality associated with the use of ECMO should be interpreted cautiously.

RESUMO

Activation of normally silent tissue-specific genes and the resulting cell "identity crisis" are the unexplored consequences of malignant epigenetic reprogramming. We designed a strategy for investigating this reprogramming, which consisted of identifying a large number of tissue-restricted genes that are epigenetically silenced in normal somatic cells and then detecting their expression in cancer. This approach led to the demonstration that large-scale "off-context" gene activations systematically occur in a variety of cancer types. In our series of 293 lung tumors, we identified an ectopic gene expression signature associated with a subset of highly aggressive tumors, which predicted poor prognosis independently of the TNM (tumor size, node positivity, and metastasis) stage or histological subtype. The ability to isolate these tumors allowed us to reveal their common molecular features characterized by the acquisition of embryonic stem cell/germ cell gene expression profiles and the down-regulation of immune response genes. The methodical recognition of ectopic gene activations in cancer cells could serve as a basis for gene signature-guided tumor stratification, as well as for the discovery of oncogenic mechanisms, and expand the understanding of the biology of very aggressive tumors.

RESUMO

A 41-year-old woman had a jeopardizing air leak from an alveolar-pleural and transdiaphragmatic fistula with pulmonary cavitation, secondary to a severe postoperative abdominal sepsis. Her condition dramatically improved by introduction, in the lower bronchus, of a one-way endobronchial valve, leading to immediate cessation of air leakage and removal of extracorporeal membrane oxygenation, and thus avoiding a lower left lobectomy with myoplasty. Furthermore, removal of the valve nine weeks later led to near-complete recovery of the left lower lobe.

RESUMO

The extraction by cervicotomy of substernal goitres may be impossible and sometimes requires the enlargement of the thoracic inlet with at least a sternal-split. We present the extraction of a posterior mediastinal substernal goitre with the application of an innovative vacuum-based suction device, previously used for the control of bleeding from the heart and great vessels in clinical and experimental conditions.
