RESUMO

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has decreased surgical activity, particularly in the field of oncology, because of the suspicion of a higher risk of COVID-19-related severe events. This study aimed to investigate the feasibility and safety of thoracic cancer surgery in the most severely affected European and Canadian regions during the COVID-19 pandemic. METHODS: The study investigators prospectively collected data on surgical procedures for malignant thoracic diseases from January 1 to April 30, 2020. The study included patients from 6 high-volume thoracic surgery departments: Nancy and Strasbourg (France), Freiburg (Germany), Milan and Turin (Italy), and Montreal (Canada). The centers involved in this research are all located in the most severely affected regions of those countries. An assessment of COVID-19-related symptoms, polymerase chain reaction (PCR)-confirmed COVID-19 infection, rates of hospital and intensive care unit admissions, and death was performed for each patient. Every deceased patient was tested for COVID-19 by PCR. RESULTS: In the study period, 731 patients who underwent 734 surgical procedures were included. In the whole cohort, 9 cases (1.2%) of COVID-19 were confirmed by PCR, including 5 in-hospital contaminants. Four patients (0.5%) needed readmission for oxygen requirements. In this subgroup, 2 patients (0.3%) needed intensive care unit and mechanical ventilatory support. The total number of deaths in the whole cohort was 22 (3%). A single death was related to COVID-19 (0.14%). CONCLUSIONS: Maintaining surgical oncologic activity in the era of the COVID-19 pandemic seems safe and feasible, with very low postoperative morbidity or mortality. To continue to offer the best care to patients who do not have COVID-19, reports on other diseases are urgently needed.

RESUMO

Cadaveric lobar lung transplantation is an alternative for patients whose chest cavities have small dimensions. We present here a case where 1 donor was used for bilateral lobar transplantations in 2 high-risk patients. Coordination between the graft preparation at the back table and the 2 concomitant lung transplant teams was necessary to minimize the ischemic injury of the grafts and to plan for adequate vascular and bronchial cuffs for both implantations.

RESUMO

BACKGROUND: Emerging data highlight different clinical behaviors according to KRAS amino acid substitutions (AASs) in patients with non-small-cell lung cancer (NSCLC). We aimed to evaluate whether different KRAS AASs were associated with different responses to chemotherapy. PATIENTS AND METHODS: We retrospectively reviewed data from 1190 patients with KRAS mutations who underwent first-line platinum-based chemotherapy for stage IV NSCLC. The response to different chemotherapy regimens was evaluated using the Response Evaluation Criteria In Solid Tumors criteria (v 1.1). Overall survival and time to progression (TTP) were secondary endpoints. RESULTS: Taxane was associated with the best response in the entire cohort (odds ratio, 2.52; 95% confidence interval [CI], 1.82-3.48; P < .001), especially in G12V patients (odds ratio, 2.15; 95% CI, 1.05-4.41; P = .036). Taxane was associated with improved TTP in the entire cohort (hazard ratio [HR], 0.31; 95% CI, 0.26-0.38; P < .001), especially in G13D patients (HR, 0.47; 95% CI, 0.22-1.01; P = .054). Pemetrexed was associated with the worst TTP in the entire cohort, particularly in G12V patients, who had the worst response rates (HR, 0.55; 95% CI, 0.30-0.99; P = .049). No impact on overall survival was observed according to different chemotherapy regimens and AASs. CONCLUSION: KRAS-specific AAS appears to induce different responses to chemotherapy regimens after first-line platinum-based chemotherapy in advanced NSCLC.

RESUMO

BACKGROUND: The prognostic value of exon 19 and 21 EGFR mutations in stage IV non-small cell lung cancer (NSCLC) is well established. OBJECTIVE: We aimed to evaluate the prognostic value of the mutations in surgically resected NSCLC. METHODS: We retrospectively reviewed data from 1798 surgically resected NSCLC adenocarcinomas between 2007 and 2017 in three departments of thoracic surgery (Nancy/Strasbourg, France, and Torino, Italy) for whom mutational status was known. Overall survival (OS) was evaluated using log-rank and Cox proportional hazard models. RESULTS: EGFR exon 19 deletion was observed in 108 patients (55.1%) and exon 21 L858R mutations were observed in 88 patients (44.9%). In stage I, the median OS was not significantly different between exons 19 and 21 (p = 0.54), while, in stage II, the median OS reached 65 months [95% confidence interval (CI) 41.67-88.33] for exon 19 mutations and decreased to 48 months for exon 21 mutations (95% CI 44.21-51.79; p = 0.027). In multivariate analysis, exon 19 deletion remained a favorable prognostic factor [hazard ratio (HR) 0.314, 95% CI 0.098-0.997; p = 0.05]. In stage III, the median OS reached 66 months (95% CI 44.67-87.32) for exon 19 mutations and decreased to 32 months for exon 21 mutations (95% CI 29.86-34.14; p = 0.03). In multivariate analysis, exon 19 deletion remained a significantly favorable prognostic factor (HR 0.165, 95% CI 0.027-0.999; p = 0.05). CONCLUSION: The prognostic value of EGFR exon 19 and 21 mutations appears to be different according to disease stage in surgically resected NSCLC.

RESUMO

Clamshell (bilateral anterolateral thoracotomy combined to transverse sternotomy) is an invasive surgical approach that is helpful in particular situations, especially bilateral lung transplantation. The closure technique remains challenging because clamshell incision can end with override, separation, or sternal pseudarthrosis complications. We describe the use of new absorbable sternal pins to stabilize the sternal closure and to help avoid additional sternal complications.

RESUMO

OBJECTIVES: The role of perioperative chemotherapy (POC) and targeted therapies in lung metastasectomy for colorectal cancer (CRC) is still subject to debate. We aimed to evaluate whether POC and targeted therapies were associated with different outcomes according to the mutational status. METHODS: We reviewed data from 223 patients who underwent pulmonary metastasectomy for CRC from 1998 to 2015 and for whom the V-Ki-ras2 Kirsten sarcoma viral oncogene homologue (KRAS) and V-raf Murine sarcoma viral oncogene homologue B1 (BRAF) mutational statuses were known. RESULTS: A total of 167 patients (74%) underwent POC: 62 (37%) received neoadjuvant therapy, 59 (35%) were in the adjuvant setting and 46 (28%) were in both the neoadjuvant and adjuvant settings. POC did not significantly influence either the loco-regional recurrence free survival (LRRFS) (P = 0.21) or the overall survival (OS) (P = 0.29). Furthermore, in cases of adjuvant chemotherapy, outcomes were not significantly different in cases of neoadjuvant chemotherapy or both neoadjuvant and adjuvant treatment (P = 0.26 for OS, P = 0.14 for LRRFS). For patients with KRAS mutation, perioperative bevacizumab was associated with a significant improvement in both LRRFS [70 months (41.58­98.42) vs 24 months (1.15­46.86), P = 0.001] and OS [101 vs 55 months (49.77­60.23), P = 0.004]. However, this benefit was only significant in cases of KRAS exon 2 codon 12 mutations [median OS: 101 months (83.97­118.02) vs 60 months (53­66.99), P < 0.001; median LRRFS: 76 months (64.62­87.38) vs 44 months (35.27­52.73), P < 0.001]. CONCLUSION: Perioperative bevacizumab appears to be beneficial in patients with exon 2 codon 12 KRAS mutations who have undergone lung metastasectomy for CRC.

RESUMO

BACKGROUND: Postpneumonectomy acute respiratory distress syndrome (ppARDS) is a life-threatening condition with a disastrous prognosis. This study assessed the efficacy of venovenous extracorporeal membrane oxygenation (VV-ECMO) in adult patients with unresponsive severe ppARDS. METHODS: We retrospectively reviewed data of all patients treated with VV-ECMO for ppARDS from January 2009 to December 2015. We calculated the Sequential Organ Failure Assessment score before ECMO insertion and monitored the subsequent mechanical ventilation settings. The primary end point was hospital survival. The secondary end point was the ability to achieve a protective ventilatory strategy allowing lung recovery on ECMO. RESULTS: VV-ECMO was indicated in 8 ppARDS patients for refractory hypoxemia (median partial pressure of arterial oxygen/fraction of inspired oxygen: 68 [range, 60 to 75] mm Hg). Median Sequential Organ Failure Assessment before ECMO was 15 (range, 12 to 17), predicting a mortality rate greater than 80%. Median duration of ECMO was 9.5 (range, 5 to 16) days. Tidal volumes and plateau pressures both decreased on ECMO (pre-ECMO tidal volume: 412 [range, 250 to 450 mL] vs ECMO tidal volume: 277 [range, 105 to 367 mL], p = 0.0156; pre-ECMO plateau pressure: 34 [range, 32 to 40] cm H2O vs ECMO plateau pressure: 24.5 [range, 23.3 to 27.3] cm H2O, p = 0.0195). ECMO could be weaned in 7 patients (87.5%). Hospital survival was 50%. CONCLUSIONS: Hospital survival was better than predicted before ECMO insertion. In severe and refractory ppARDS, VV-ECMO allows lung recovery and therefore increased survival.

RESUMO

BACKGROUND: Lobectomy for benign lung disease is renowned to be technically complex and to be subjected to an increased complication rate. The objective of this study was to evaluate whether the results obtained with video-assisted surgery (VATS) in benign disease are comparable to those obtained in oncologic surgery, where VATS has been validated. METHODS: We have reviewed the files of 246 consecutive patients who underwent VATS lobectomy from January 2012 to August 2015. The cohort was divided into two groups according to pathology (benign or malignant). Outcome parameters on scrutiny were demographics, pathology, duration of air leak, drainage and hospital stay, conversion, and perioperative complication rate. Comparisons were made with the χ 2 test and Student's t test; any p value ≤0.05 was considered as significant. RESULTS: Group 1 (36 patients) included patients who underwent lobectomy for benign disease and group 2 (210 patients) patients affected by lung cancer or pulmonary metastases. The two groups differed with reference to age (p < 0.001), history of cancer (p < 0.001), history of stroke (p = 0.05), and the presence of pleural adhesions (p = 0.03). There was no difference for duration of air leaks, chest tube drainage and hospital stay, conversion rate, and perioperative complication rate. CONCLUSIONS: We conclude that pathology did not impact on outcomes after VATS lobectomy. This study suggests that VATS is as a safe option in selected patients with benign disease requiring lobectomy, despite a more complex technical context.

RESUMO

Management of stage IIIA-N2 non-small cell lung cancer is still matter of ongoing controversy. The debate is flawed by the heterogeneity of this group of patients, lack of strong evidence from controlled trials, diverging treatment strategies, and hesitating estimation of prognosis. Surgery is credited a survival advantage in a trimodality setting. For many teams, N2 is by principle managed with induction chemotherapy, followed by surgery if the patient is down-staged. However, surgery remains a suitable option even in case of persistent N2. On the other hand, outcomes are comparable, regardless whether chemotherapy has been given as induction or adjuvant treatment. Hence, upfront surgery without invasive staging, followed by adjuvant therapies, appears reasonable in resectable single station N2 disease, simplifying patient care and reducing cost. We expect that molecular biomarkers will improve estimation of prognosis and patient selection in the future.

RESUMO

OBJECTIVES: Epidermal growth factor receptor (mEGFR) and v-Ki-ras2 Kirsten rat sarcoma viral oncogen homologue (mKRAS) mutations are the two main oncogenic drivers in resected non-small-cell lung cancer (NSCLC). We aimed to evaluate the correlation between histopathological prognostic factors and these mutations in resected NSCLC. METHODS: We retrospectively reviewed data from 841 patients who underwent a surgical resection with a curative intent for NSCLC between 2007 and 2012. RESULTS: KRAS mutations were observed in 255 patients (32%) and mEGFR in 103 patients (12%). A correlation was observed between mKRAS patients and lymph node involvement [Cramer's V: 0.451, P < 0.001, OR: 7.5 (95% CI: 5.3-10.7), P < 0.001]. Otherwise, a correlation was observed between mKRAS and the risk of harbouring 2 N2 stations [Cramer's V: 0.235, P = 0.02, OR: 3.04 (95% CI: 1.5-6.3), P = 0.004]. High lymph node ratio and angioinvasion were also significantly more frequent in mKRAS [Cramer's V: 0.373, P < 0.001, OR: 6.37 (95% CI: 3.9-10.5), P < 0.001; and Cramer's V: 0.269, P < 0.001, OR: 3.25 (95% CI: 2.4-4.4), P < 0.001, respectively]. Skip N2 and microscopic N2 were significantly more frequent in mEGFR [Cramer's V: 0.459, P < 0.001, OR: 18 (95% CI: 5.6-57.8), P < 0.001; and (Cramer's V: 0.45, P < 0.001 OR: 21.14 (95% CI: 9.2-48.3), P < 0.001, respectively]. CONCLUSIONS: We observed a correlation between mKRAS and negative histopathological prognostic factors and between mEGFR and positive prognostic factors. One can wonder whether histopathological prognostic factors are only clinical reflections of molecular alterations.

RESUMO

In thoracic surgery, extracorporeal life support (ECLS) techniques are performed to (I) provide a short to mid term extracorporeal mechanical support; (II) realize the gas exchanges; and (III)-depending the configuration of the circuit-substitute the failed heart function. The objective of this review is to describe the rational of the different ECLS techniques used in thoracic surgery and lung transplantation (LTx) with a specific attention to the vascular access. Venovenous extracorporeal membrane oxygenation (VV ECMO) is the most common ECLS technique used in thoracic surgery and represents the best strategy to support the lung function. VV ECMO needs peripheral vascular access. The selection between his double-site or single-site configuration should be decided according the level of O2 requirements, the nosological context, and the interest to perform an ECLS ambulatory strategy. Venoarterial (VA) ECMO uses peripheral and/or central cannulation sites. Central VA ECMO is mainly used in LTx instead a conventional cardiopulmonary bypass (CPB) to decrease the risk of hemorrhagic issues and the rate of primary graft dysfunction (PGD). Peripheral VA ECMO is traditionally realized in a femoro-femoral configuration. Femoro-femoral VA ECMO allows a cardiocirculatory support but does not provide an appropriate oxygenation of the brain and the heart. The isolated hypercapnic failure is currently supported by extracorporeal CO2 removal (ECCO2R) devices inserted in jugular or subclavian veins. The interest of the Novalung (Novalung GmbH, Hechingen, Germany) persists due to his central configuration indicated to bridge to LTx patients suffering from pulmonary hypertension. The increasing panel of ECLS technologies available in thoracic surgery is the results of a century of clinical practices, engineering progress, and improvements of physiological knowledges. The selection of the ECLS technique-and therefore the vascular access to implant the device-for a given nosological context trends to be defined according an evidence-based medicine.

RESUMO

BACKGROUND: Identifying patients who will experience lung cancer recurrence after surgery remains a challenge. We aimed to evaluate whether mutant forms of epidermal growth factor receptor (EGFR) and Kirsten rat sarcoma viral oncogene homolog (KRAS) (mEGFR and mKRAS) are useful biomarkers in resected non-small cell lung cancer (NSCLC). METHODS: We retrospectively reviewed data from 841 patients who underwent surgery and molecular testing for NSCLC between 2007 and 2012. RESULTS: mEGFR was observed in 103 patients (12.2%), and mKRAS in 265 (31.5%). The median overall survival (OS) and time to recurrence (TTR) were significantly lower for mKRAS (OS: 43 months; TTR: 19 months) compared with mEGFR (OS: 67 months; TTR: 24 months) and wild-type patients (OS: 55 months; disease-free survival (DFS): 24 months). Patients with KRAS G12V exhibited worse OS and TTR compared with the entire cohort (OS: KRAS G12V: 26 months vs COHORT: 60 months; DFS: KRAS G12V: 15 months vs COHORT: 24 months). These results were confirmed using multivariate analyses (non-G12V status, hazard ratio (HR): 0.43 (confidence interval: 0.28-0.65), P<0.0001 for OS; HR: 0.67 (0.48-0.92), P=0.01 for TTR). Risk of recurrence was significantly lower for non-KRAS G12V (HR: 0.01, (0.001-0.08), P<0.0001). CONCLUSIONS: mKRAS and mEGFR may predict survival and recurrence in early stages of NSCLC. Patients with KRAS G12V exhibited worse OS and higher recurrence incidences.

RESUMO

We report a case of partial anomalous pulmonary venous return from the left upper lobe in a donor lung discovered during lung transplantation. The upper lobe vein could be implanted successfully into the donor atrial cuff to restore physiologic venous drainage. The abnormality was retrospectively identified on the donor's chest computed tomographic scan. Cardiac magnetic resonance imaging performed in the recipient 6 months after transplantation demonstrated patent left pulmonary venous drainage. This is the third reported case of partial anomalous pulmonary venous return in a donor lung, but the first description of direct ex vivo suture into the donor cuff.

RESUMO

OBJECTIVES: Multimodal management of N2 non-small-cell lung cancer is still a matter of debate. In particular, the place of surgery for persistent N2 after induction treatment is controversial and surgery is usually reserved for patients experiencing a mediastinal downstaging (pN1 and pN0). We aimed to evaluate whether there might exist subgroups of pN2 according to the lymph node ratio (LNR). METHODS: Between 1996 and 2012, we retrospectively reviewed the data from 152 potentially resectable cN2 patients who underwent an induction treatment before surgery. RESULTS: The median follow-up time was 32 months (2-112). The average age at the time of diagnosis was 58.52 ± 10.47 years. In univariate analysis, overall survival (OS) was significantly influenced by extracapsular spread (32 ± 5.33 vs 24 ± 12.73 months, P = 0.01), pN after surgery (65 ± 2.45 months for pN0, 44 ± 2.14 months for pN1 and 19 ± 1.72 months for pN2, P <0.0001) and LNR ≥ 1/3 (30 ± 3.77 months vs 16 ± 1.39 months, P <0.0001). When pN0 and pN1 patients were staged according to the LNR, the OS was divided by two for pN1 patients with an LNR ≥ 1/3 (48 ± 2.64 months vs 26 ± 5.65 months, P <0.001), whereas it decreased from 26 ± 0.87 to 15 ± 1.85 months (P <0.0001) for pN2 patients. OS was significantly better with adjuvant radio-chemotherapy than with chemotherapy or radiation therapy alone (P <0.0001). In multivariate analysis, mediastinal downstaging {Hazard Ratio (HR): 0.184 (95% confidence interval (CI): 0.084-0.403), P <0.0001} and LNR [HR: 0.359 (95% CI: 0.194-0.665], P = 0.001) remained significantly independent prognostic factors. CONCLUSIONS: The LNR may potentially identify subgroups of pN+ patients and allow enhancement of adjuvant treatments. Because pN2 with a low LNR had an equivalent survival to pN1 with a high LNR, mediastinal downstaging does not seem to be a sufficient prognostic factor to exclude patients after induction treatment from surgery.

OBJECTIVES: Data on thoracic lymph node involvement (LNI) in lung metastasis of colorectal cancer (CRC) are conflicting, with a 5-year overall survival (OS) ranging from 6 to 40%. We aimed to evaluate whether there are subgroups of patients according to the lymph node ratio (LNR). METHODS: We retrospectively reviewed the data from 106 patients who underwent a thoracic procedure for CRC lung metastasis with pathologically proven thoracic LNI. RESULTS: In the univariate analysis, the median OS was significantly poorer for a pN2 location of LNI (26 vs 16 months, P = 0.04), LNR ≥50% (30 vs 17 months, P = 0.005), high preoperative CEA (32 vs 16 months, P = 0.02), hepatic metastases (27 vs 11 months, P <0.0001) and disease-free survival < 24 months (32 vs 17 months, P = 0.05). When pN1 and pN2 patients were staged according to the LNR, the median OS was significantly better for an LNR <50% (27 vs 17 months for pN1, 32 vs 12 months for pN2, P = 0.01). In the multivariate analysis, a high preoperative CEA [hazard ratio (HR): 2.256 (1.051-4.841), P = 0.04], pN1 status [HR: 0.337 (0.162-0.7), P = 0.004] and the absence of hepatic metastases [HR: 0.395 (0.180-0.687), P = 0.02] remained significant prognostic factors. There was an upward trend for patients with LNR <50% [HR: 0.565 (0.296-1.082), P = 0.08]. Otherwise, low LNR was significantly associated with a decreased risk of loco-regional recurrence (HR: 0.36, 95% confidence intervals: 0.14-0.96, P = 0.04). CONCLUSIONS: The LNR seems to be a more reliable prognostic factor than LNI for CRC lung metastasis. Prospective studies are necessary.

RESUMO

A best evidence topic was constructed according to a structured protocol. The question addressed was whether daily routine (DR) chest radiographs (CXRs) are necessary after pulmonary surgery in adult patients. Of the 66 papers found using a report search, seven presented the best evidence to answer the clinical question. Four of these seven studies specifically addressed post-cardiothoracic adult patients. Three of these seven studies addressed intensive care unit (ICU) patients and included post-cardiothoracic adult patients in well-designed studies. Six of these seven studies compared the DR CXRs strategy to the clinically indicated, on-demand (OD) CXRs strategy. Another study analysed the clinical impact of ceasing to perform the DR, postoperative, post-chest tubes removal CXRs. The authors, journal, date and country of publication, study type, group studied, relevant outcomes and results of these papers are given. We conclude that, on the whole, the seven studies are unanimously in favour of forgoing DR CXRs after lung resection and advocate OD CXRs. One study suggested that hypoxic patients could benefit from a DR CXRs strategy, while other studies failed to identify any subgroup for whom performing DR CXRs was beneficial. Indeed, DR CXRs, commonly taken after thoracic surgery, have poor diagnostic and therapeutic value. Eliminating them for adult patients having undergone thoracic surgery significantly decreases the number of CXRs per patient without increasing mortality rates, length of hospital stays (LOSs), readmission rates and adverse events. Hence, current evidence shows that DR CXRs could be forgone after lung resection because OD CXRs, recommended by clinical monitoring, have a better impact on management and have not been proved to negatively affect patient outcomes. Moreover, an OD CXRs strategy lowers the cost of care. Nevertheless, an OD CXRs strategy requires close clinical monitoring by experienced surgeons and dedicated intensivists. However, given the published studies' low level of evidence, prospective and randomized trials, specifically after thoracic surgery, are necessary in order to confirm these results.

RESUMO

Extracorporeal membrane oxygenation (ECMO) is used for refractory respiratory failure. Normally, ECMO is implanted in intubated patients as a last resort. We report the case of a non-intubated patient who benefited from veno-venous (VV) ECMO. A 35-year old cystic fibrosis man presented a severe respiratory decompensation with refractory hypercapnia. We opted for an ECMO instead of mechanical ventilation (MV). We implanted a double lumen bi-cava cannula (DLC) (Avalon Elite(TM)) in the right jugular vein. Before ECMO implantation, the patient presented refractory respiratory failure (pH = 7.1, PaO(2) = 83 mmHg, PaCO(2 )= 103 mmHg). We proposed that the patient be placed on the high emergency lung transplantation waiting list after failure to wean him from ECMO. This registration was effective 10 days after ECMO implantation. The patient was grafted the next day. Under ECMO, mean PaO(2), PaCO(2) and TCA were 80.6 ± 14.2, 53.8 ± 6.4 mmHg and 56.2 ± 9.7 s, respectively. The patient could eat, drink, talk and practice chest physiotherapy. The evolution was uneventful under ECMO. Weaning from ECMO was done in the operating theatre after transplantation. VV ECMO with DLC is safe and feasible in non-intubated patients. It avoids potential complications of MV, and allows respiratory assistance as bridge to transplantation.
