Impact of interstitial lung disease on short-term and long-term survival of patients undergoing surgery for non-small-cell lung cancer: analysis of risk factors

OBJECTIVES The study aimed to determine the impact of interstitial lung disease (ILD) on postoperative morbidity, mortality and long-term survival of patients with non-small-cell lung cancer (NSCLC) undergoing pulmonary resection. METHODS We performed a retrospective chart review of 775 consecutive patients who had undergone lung resection for NSCLC between 2000 and 2009. ILD, defined by medical history, physical examination and abnormalities compatible with bilateral lung fibrosis on high-resolution computed tomography, was diagnosed in 37 (4.8%) patients (ILD group). The remaining 738 patients were classified as non-ILD (control group). We also attempted to identify the predictive factors for early and late survival in patients with ILD following pulmonary resection. RESULTS There was no significant difference between the two groups in terms of age (69 vs 66 years), sex (79 vs 72% male), smoking history (93 vs 90% smokers), forced expiratory volume in 1 s % of predicted (89 vs 84%), predicted values of forced vital capacity (FVC)% (92 vs 94%), types of surgical resection and histology. Patients with ILD had a higher incidence of postoperative acute respiratory distress syndrome (ARDS; 13 vs 1.8%, P < 0.01) and higher postoperative mortality (8 vs 1.4%, P < 0.01). The overall 5-year survival rate was 52% in the ILD and 65% in the non-ILD patients, respectively (P = 0.019). In the ILD group, at the median follow-up of 26 months (range 4-119), 19 (51%) patients were still alive and 18 (49%) had died in the ILD group. The major cause of late death was respiratory failure due to the progression of fibrosis (n = 7, 39%). In the ILD group, lower preoperative FVC% (mean 77 vs 93%, P < 0.01) and lower diffusing capacity of the lung for carbon monoxide (DLCO%; 47 vs 62%; P < 0.01) were significantly associated with postoperative ARDS. CONCLUSIONS In conclusion, major lung resection in patients with NSCLC and ILD is associated with an increased postoperative morbidity and mortality. Patients with a low preoperative FVC% should be carefully assessed prior to undergoing surgery, particularly in the presence of a lower DLCO%. Long-term survival is significantly lower when compared with patients without ILD, but still achievable in a substantial subgroup. Thus, surgery can be offered to properly selected patients with lung cancer and ILD, keeping in mind the risk of respiratory failure during the evaluation of such patients.

Uniportal thoracoscopic decortication for pleural empyema and the role of ultrasonographic preoperative staging

Objectives The surgical approach to chronic pleural empyema is still controversial. Video-assisted thoracic surgery (VATS) debridement and decortication has shown favourable outcomes, while the uniportal VATS (U-VATS) approach is still anecdotal. We report our experience with ultrasonographic (US) preoperative staging followed by U-VATS decortication for pleural empyema. Methods We performed a retrospective analysis of patients who underwent surgical treatment of stage II and stage III pleural empyema from 2012 to 2015. Pre-, intra- and postoperative data were investigated to evaluate outcomes including postoperative complications and disease recurrence. Results were analysed according to preoperative US appearance of pleural space (stages A-E) and surgical approach (thoracotomy vs U-VATS). Results We performed 30 (47%) uniportal thoracoscopic pleural decortication and 34 (53%) open decortication for empyema in stage II (40%) or III (60%) obtaining a complete debridement and decortication in all patients. In-hospital mortality was zero and overall morbidity was 29%. U-VATS was associated with lower blood loss (118 ±  80 ml vs 247  ±  140 ml P  < 0.001), lower chest tubes duration (5.6 ±  1.4 vs 10.6  ±  4.4 days P  < 0.001), shorter hospital stay (6.7  ±  1.9 vs 12.2  ± 4.7 days, P  < 0.001) and lower complications (10% vs 16%, P  < 0.001). Elevated US patterns (D-E) are associated with thoracotomy, higher blood loss, operative time and a significant incidence of complications. Conclusions Uniportal thoracoscopic decortication for pleural empyema is a safe and effective approach for selected patients based on a combination of clinical and imaging staging. US patterns well corresponded with intraoperative pleural findings and showed a prognostic value.

Afatinib with subsequent surgery in stage III NSCLC with EGFR mutation: Lessons learned from two clinical experiences:

Afatinib, a second-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, is effective as first-line treatment in patients with EGFR-mutated non-small cell lung cancer (NSCLC). We report 2 cases of EGFR-mutated locally advanced NSCLC treated in neoadjuvant setting with EGFR tyrosine kinase inhibitor at University of Florence/Careggi Hospital. In both cases, afatinib was used for up to 3 months, until 1 week before surgery. Both patients achieved significant reduction (downstaging) of the pulmonary mass and lymphadenopathies and after surgery, it was decided for both cases to restore afatinib treatment up to a further 4 months. Both patients experienced local and distant disease relapses after 9 and 10 months, respectively, and then we restored the afatinib treatment.

Fissureless fissure-last video assisted thoracoscopic lobectomy: always? never? sometimes

Lung surgery has changed during the last decade and video-assisted thoracic surgery (VATS) techniques have been introduced and implemented with the aim to reduce hospital stay, perioperative complications, and to obtain a faster recovery to habitual activities. However, one of the commonest complications after lung surgery still remains prolonged air leak (PAL), reported in 8–15% of cases and leading to a longer chest tube duration, length of stay (LOS), and consequently to higher costs and more risks of pleural infections (1,2).

Long-term results after surgical treatment of the dominant lung adenocarcinoma associated with ground-glass opacities

Background To evaluate the effect of first-time and eventual reiterative surgery on overall survival (OS) and disease-free survival (DFS) in Caucasian patients affected by an invasive adenocarcinoma (ADC) with at least another ground-glass opacity (GGO). Methods We analysed 47 patients operated on for lung ADC, identified as main cancer (MC), with at least one synchronous GGO, from January 2003 to March 2017. Characteristics associated with the evolution of GGOs were investigated with logistic regression and overall and DFS were evaluated with Kaplan-Meier method. Results Forty-two (89%) patients received an anatomic resection of the MC, 5 patients were treated by a single or multiple wedge resections. In total, 9 (19.1%) patients had all the lesions resected undergoing simultaneous resection of ipsilateral GGOs at first surgery while the remaining 38 (80.9%) patients still had at least one GGO that was followed up by serial CT scan. At the median follow-up of 41 months, GGO evolved in 16 (42.1%) patients. The presence of solid component at the initial CT scan was the only risk factor for evolution of the GGO. Thirteen patients underwent surgical resection showing an invasive ADC in 9 patients, MIA in 3 and AIS in 1. New GGOs developed in 7 (14.9%) patients, in which three underwent surgery showing the presence of solid ADC, MIA and AAH. OS rate at 5 years was 97.4%. DFS at 3 years was 82% and was significantly influenced by the stage of MC. Conclusions Patients affected by an invasive ADC with at least another GGO nodule enjoy good OS and DFS with a surgical reiterative approach. Part-solid GGO is associated with GGO progression requiring treatment, but OS is not influenced by the new onset or evolution of GGOs. DFS is affected by the stage of the MC which dictates the treatment strategy.

Venous outlet syndrome caused by capillary hemangioma of the subclavian vein

We report a case of intravenous lobular capillary hemangioma in the subclavian vein, causing venous thoracic outlet syndrome. A 32-year-old woman was referred to our unit with facial and left arm oedema. Ultrasound evaluation, computed tomography and magnetic resonance imaging showed a hypervascular mass in the middle portion of the subclavian vein, with arrest of venous flow. Through an infraclavicular approach, we excised the venous axis with the endovascular palpable tumour that extended from the axillary-subclavian junction to the jugular-subclavian junction, without reconstruction. The postoperative period was uneventful. The patient recovered well without recurrence at one year from surgery.

Thoracoscopic lobectomy for locally advanced-stage non-small cell lung cancer is a feasible and safe approach: analysis from multi-institutional national database

Background Video-assisted thoracoscopic lobectomy (VATS-L) is a well-established approach for early-stage non-small cell lung cancer (NSCLC) with functional and oncological outcomes similar to thoracotomy. The role of VATS-L in locally advanced stage of NSCLC has not been well standardized. The objective of this study was to evaluate the state of the art in Italy of VATS-L for NSCLC advanced stages using the data from the Italian VATS Group Database. Methods Between 1st January 2014 and 31th May 2017, 3,720 patients underwent VATS-L at VATS Group participating centres and included in the VATS Group database. Patients were divided into two groups: (A) early stages and (B) locally-advanced stages (tumours with dimension >5 cm (cT2b), cT3, cT4 and/or tumours that received neo-adjuvant chemotherapy). A retrospective study was performed, to evaluate the safety and the oncological adequacy of VATS-L comparing peri-operative outcomes and pathological data. Results A total of 3,266 (87.7%) patients were included into the group A, while 454 (13.3%) patients formed the group B. VATS-L for locally advanced-stage NSCLC is associated with a longer procedure, a higher estimated blood loss, an increased incidence of conversion (9.3% vs. 13.0%, P=0.018) and a significant higher number of total, hilar and mediastinal dissected lymph nodes. The mortality rate (1.6% vs. 1.5%), the proportion of patients who suffered any complication (24.8% vs. 29.1%) and the hospitalization were not statistically different between the two groups (P=0.880, 0.057 and 0.660, respectively); the overall complication rate was statistically higher in group B (30.4% vs. 37.0%; P=0.04). Patients of group B who required conversion had a statistically significantly higher operative time (P<0.01), blood loss (P<0.01) and hospital stay (P<0.01), but not significantly higher overall morbidity rate (35.5% vs. 28.0%) compared with patients completely operated by VATS. Conclusions VATS-L for locally advanced-stage NSCLC in Italy is a safe and effective procedure when performed in appropriately selected patients, ensuring peri-operative results similar to those obtained in early-stage tumours.

Short and long-term results of sternectomy for sternal tumours

Background We analyzed our experience in sternal resections (SRs) for primary or secondary neoplasm focusing on technical aspects of reconstruction, post-operative outcomes and long term survival. Methods From January 2005 to December 2015, 36 patients (24 males, 67%) underwent surgical excision of primary (chondrosarcoma n=18 patients, 50%; osteosarcoma n=2, 6%; Ewing sarcoma n=1, 3%; other n=2, 6%) or secondary (breast cancer n=7, 19%; kidney carcinoma n=2, 6%) sternal tumour. We performed n=30 partial sternectomy and n=6 total sternectomy with en-bloc resection of the sternocostal cartilages in all patient and extended resection in 7 patients. Stability was obtained with prosthetic material, rigid and non-rigid and a muscular flap: rigid material [Strasbourg Thoracic Osteosynthesis System (STRATOS), MedXpert GmbH] and muscle flap n=11 (30.6%); polytetrafluoroethylene patch and muscle flap n=6 (16.7%); muscle flap alone n=19 (52.8%). Results The 30-day mortality rate was 0, overall complication rate was 19%. The median ICU stay was 1.5 days and mean hospital stay was 10.6±5.9 days. We obtained a complete (R0) resection in all patients. Overall survival (OS) at 5 and 10 years were 59% and 40%; in the group of primary neoplasm OS rate at 5 and 10 years was 79% and 54%. Disease free survival (DFS) rate at 5 years was 61%. Higher grading was identified as negative prognostic factor. Conclusions Wide radical resections of anterior chest wall are basilar in a multimodality treatment for primary or metastatic neoplasm of the sternum. Stabilization with titanium bars and clips provides rigidity of chest wall with good functional results.
