OBJECTIVES: Lung cancer is increasingly diagnosed as a second cancer. Our goal was to analyse the characteristics and outcomes of early-stage resected lung adenocarcinomas in patients with previous cancers (PC) and correlations with adenocarcinoma subtypes.METHODS: We retrospectively reviewed data of patients radically operated on for stage I-II lung adenocarcinoma in 9 thoracic surgery departments between 2014 and 2017. Overall survival (OS) and time to disease relapse were evaluated between subgroups.RESULTS: We included 700 consecutive patients. PC were present in 260 (37.1%). Breast adenocarcinoma, lung cancer and prostate cancer were the most frequent (21.5%, 11.5% and 11.2%, respectively). No significant differences in OS were observed between the PC and non-PC groups (P = 0.378), with 31 and 75 deaths, respectively. Patients with PC had smaller tumours and were more likely to receive sublobar resection and to be operated on with a minimally invasive approach. Previous gastric cancer (P = 0.042) and synchronous PC (when diagnosed up to 6 months before lung adenocarcinoma; P = 0.044) were related, with a worse OS. Colon and breast adenocarcinomas and melanomas were significantly related to a lower incidence of high grade (solid or micropapillary, P = 0.0039, P = 0.005 and P = 0.028 respectively), whereas patients affected by a previous lymphoma had a higher incidence of a micropapillary pattern (P = 0.008).CONCLUSIONS: In patients with PC, we found smaller tumours more frequently treated with minimally invasive techniques and sublobar resection, probably due to a more careful follow-up. The impact on survival is not uniform and predictable; however, breast and colon cancers and melanoma showed a lower incidence of solid or micropapillary patterns whereas patients with lymphomas had a higher incidence of a micropapillary pattern.

BackgroundAlthough the feasibility and safety of Uniportal-Video-Assisted thoracic surgery (U-VATS) has been proven, its surgical effectiveness is still debated. The aim of this study is to assess the equivalence of the U-VATS approach compared with an open technique in terms of surgical (nodal-upstaging, complications, and post-operative results) and short-term survival outcomes. MethodsThe clinical data of patients undergoing lobectomy for NSCLC at our center, from January 2014 to December 2019, were analyzed retrospectively. All patients undergoing open or U-VATS lobectomy with lymphadenectomy for early-stage lung cancer (cT1-T3N0, stages IA-IIB) were included in the study. Only 230 patients satisfied the inclusion criteria. Group bias was reduced through 1:1 propensity score matching, which resulted in 46 patients in each group (open surgery and U-VATS). ResultsThe intra- and post-operative mortality were null in both groups. There was no difference in the post-operative complications (p: 1.00) between U-VATS and open lobectomy. There was also no recorded difference in the pathological nodal up-staging [11 (23.9%) after thoracotomy vs. 8 (17.4%) after U-VATS, p: 0.440). The chest tube duration was longer in the open group (p: 0.025), with a higher post-operative pain (p: 0.001). Additionally, the 3-year overall survival (OS) was 78% after U-VATS lobectomy vs. 74% after open lobectomy (p: 0.204), while 3-year disease-specific survival (DSS) was 97 vs. 89% (p: 0.371), respectively. The 3-year disease-free survival (DFS) was 62% in the U-VATS group and 66% in the thoracotomy group, respectively (p: 0.917). ConclusionsUniportal-VATS lobectomy for the treatment of early-stage lung cancer seems to be a safe and effective technique with similar surgical and short-term survival outcomes as open surgery, but with lower post-operative pain and shorter in-hospital stay.

Background: Thymic carcinoma is a rare and highly malignant tumor with a dismal prognosis, which occasionally coexists with myasthenia gravis (MG). This study aims to investigate the MG incidence on a surgical cohort of patients with thymic carcinoma and to explore its influence on long-term survival. Methods: the prospectively collected data from the ESTS database on thymic epithelial tumors were reviewed. Clinical, pathological, and survival information on thymic carcinoma were analyzed. Results: the analysis was conducted on 203 patients, with an equal gender distribution (96 males and 107 females). MG was detected in 22 (10.8%) patients, more frequently elderly (>60 years, p = 0.048) and male (p = 0.003). Induction therapy was performed in 22 (10.8%) cases. After surgery, 120 (59.1%) patients had a Masaoka stage II-III while complete resection (R0) was achieved in 158 (77.8%). Adjuvant therapy was performed in 68 cases. Mean follow-up was 60 (SD = 14) months. The 3-year, 5-year and 10-year survival rates were 79%, 75% and 63%, respectively. MG did not seem to influence long-term survival (5-year survival in non-MG-TCs 78% vs. 50% in MG-TCs, p = ns) as age < 60 years, female gender, early Masaoka stage, and postoperative radiotherapy did, conversely. Conclusions: myasthenia occurred in about 10% of thymic carcinomas and it did not seem to affect significantly the long-term prognosis in surgically treated thymic carcinoma-patients.

Aims To explore the long-term survival in lung cancer patients with persistent mediastinal lymph nodal disease after neoadjuvant followed by surgical resection and to analyse prognostic factors in this specific subset of patients Background Surgery in non-small-cell lung cancer (NSCLC) patients with N2-disease after neoadjuvant therapy (NAD) has been debated and has been even more questioned with the advent of immunotherapy. Objective Describe long-term results of a multimodal approach in locally-advanced NSCLC patients with persistence of N2-disease and identify prognostic factors to target the strategy of care. Methods We retrospectively reviewed data of 121 consecutive Stage IIIA-N2 NSCLC patients who underwent NAD (chemoradiotherapy or chemotherapy) from 01/00 to 12/19, focusing our analysis on 37 patients with persistent N2s status after surgery. Kaplan-Meier and Cox regression analysis explored the associations between mortality and potential risk factors. Results The 5-year survival was 29.8%. Cox regression analysis suggested that young age (HR=0.98, C.I.95%: 0.97- 1.00; p=0.062), male sex (HR=3.8,C.I.95%:1.06-13.73;p=0.04), and adjuvant therapy (HR=6.81,C.I.95%:0.96-53.94;p=0.06) influenced long-term outcomes in these patients. Conclusion We herein observed suboptimal long-term results in this NSCLC patient subset, and, considering emerging results adopting immunotherapy following chemoradiotherapy, surgery should be carefully considered in very selected cases (young and clinically fit patients) and combined with adjuvant therapy after surgery.

In the last decade, the emergence of effective systemic therapies (ESTs) in the form of both targeted and immuno-based therapies has revolutionized the treatment of patients with advanced stage III and stage IV melanoma. Even though lungs represent the most frequent site of melanoma metastases, only limited data are available on the role of surgery in isolated pulmonary metastases from malignant melanoma (PmMM) in the era of ESTs. The aim of this study is to describe the outcomes of patients who underwent metastasectomy of PmMM in the era of ESTs, in order to identify prognostic factors affecting survival and to provide a framework for more informed patient selection of treatmeant with lung surgery in the future. Clinical data of 183 patients who underwent metastasectomy of PmMM between June 2008 and June 2021 were collected among four Italian Thoracic Centers. The main clinical, surgical and oncological variables reviewed were: sex, comorbidities, previous oncological history, melanoma histotypes and primary site, date of primary cancer surgical treatment, melanoma growth phase, Breslow thickness, mutation pattern disease, stage at diagnosis, metastatic sites, DFI (Disease Free Interval), characteristics of lung metastases (number, side, dimension, type of resection), adjuvant therapy after lung metastasectomy, site of recurrence, disease-free survival (DFS) and cancer-specific survival (CSS; defined as the time interval between the first melanoma resection or lung metastasectomy and death from cancer). All patients underwent surgical resection of the primary melanoma before lung metastasectomy. Twenty-six (14.2%) patients already had a synchronous lung metastasis at the time of primary melanoma diagnosis. A wedge resection was performed in 95.6% of cases to radically remove the pulmonary localizations, while an anatomical resection was necessary in the remaining cases. The incidence of major post-operative complications was null, while only 21 patients (11.5%) dev

Alveolo-pleural fistula remains a serious post-operative complication in lung cancer patients after surgery, which is associated with prolonged hospital stay and higher healthcare costs. The aim of this study is to evaluate the efficacy of a polyglycol acid (PGA)-sheet known as Neoveil in preventing post-operative air-leak in cases of detected intra-operative air-leak after lung resection. Between 11/2021 and 7/2022, a total of 329 non-small cell lung cancer (NSCLC) patients were surgically treated in two institutions. Major lung resections were performed in 251 cases. Among them, 44 patients with significant intra-operative air-leak at surgery were treated by reinforcing staple lines with Neoveil (study group). On the other hand, a historical group (selected by propensity score matched analysis) consisting of 44 lung cancer patients with significant intra-operative air leak treated by methods other than the application of sealant patches were considered as the control group. The presence of prolonged air-leak (primary endpoint), pleural drainage duration, hospital stay, and post-operative complication rates were evaluated. The results showed that prolonged air-leak (>5 days after surgery) was not observed in study group, while this event occurred in four patients (9.1%) in the control group. Additionally, a substantial reduction (despite not statistically significant) in the chest tube removal was noted in the study group with respect to the control group (3.5 vs. 4.5, p = 0.189). In addition, a significant decrease in hospital stay (4 vs. 6 days, p = 0.045) and a reduction in post-operative complications (2 vs. 10, p = 0.015) were observed in the study group when compared with the control group. Therefore, in cases associated with intra-operative air-leak after major lung resection, Neoveil was considered a safer and more effective aerostatic tool and represents a viable option during surgical procedures.

Background and Objectives The Masoka-Koga and tumor node metastases staging systems for thymoma are based on structures involved, but the prognostic role of the number of infiltrated/involved structures is still debated. We analyzed the prognostic role of involved structures and their combinations in locally advanced thymomas patients. Methods Data on 174 surgically treated locally advanced thymoma patients from 1/01/1990 to 31/12/2015 were reviewed. Clinical and pathological characteristic, involved structures, number of involved structures and different combinations were correlated to cancer specific survival (CSS) using Kaplan-Meier product-limit method. Results Five and 10-year CSS was 92% and 87%. Masaoka Stage 3 (p < 0.001), absence of pericardial involvement (p = 0.001), number of involved structures (p = 0.018), R0 (p < 0.001) and adjuvant radiotherapy (p = 0.008) were favorable prognostic CSS factors. A significant better prognosis was present in <= 2 involved structures vs >2 involved structures (5- and 10-year CSS: 95% and 93% vs. 80% and 51%). Multivariable analysis confirmed as independent prognostic factor R0 (p = 0.033, hazard ratio [HR]: 0.093, 95% confidence interval [CI] 0.010-0.827) and number of involved structures (p = 0.046, HR: 0.187, 95% CI: 0.036-0.968). In Masaoka Stage 3, patients with <= 2 involved structures had a significant better CSS than patients with >2 (10-year CSS: 98% vs. 73%, p = 0.008). Conclusions The number of involved structures and the concomitant involvement of the pericardium seems to be associated with a poor prognosis in surgically treated advanced thymoma patients.

BACKGROUND: The optimal thoracoscopic sympathetic surgery for primary palmar and/or axillary hyperhidrosis (PPAH) is still unclear because of lack of uniform technique and qualitative/quantitative scales for definition of results. The aims of this study were to compare long-term outcomes based on the surgical technique and the level of sympathetic trunk interruption by clipping and to assess postoperative compensatory sweating (CS), patients' satisfaction, and quality of life (QoL).MATERIALS AND METHODS: Between September 2009 and April 2016, 94 patients who underwent 2-stage bilateral thoracoscopic rib-oriented (R) sympathetic clipping were prospectively followed up through the administration of standardized preoperative and postoperative questionnaires.Thirty-four (36.2%) patients underwent single-port transaxillary access instead of the standard two 5-mm incisions. The level of sympathetic clipping for PPAH was R3+4(top and bottom); in patients who complained associated facial or plantar hyperhidrosis R2-bottom and R5-top were clipped, respectively. Seventy-five patients completed bilateral surgery.RESULTS: There were no significant differences between single-port and biportal video-assisted thoracoscopic surgery in terms of operative times and postoperative results. At a mean follow-up of 72 (SD: 26) months, CS was reported in 42 (56%) patients, severe only in 6 (8%). It was higher in the case of R2-bottom clipping (P=0.03). Thirty-one of 60 (51.6%) patients who had a plantar hyperhidrosis declared an improvement of feet sweating after surgery. Postoperative satisfaction was excellent (86.11% on a 0 to 100 scale) and 95.4% of patients declared an improvement in QoL, which was statistically significant in all evaluated parameters. These results were not related to the level of clipping.CONCLUSION: Thoracoscopic R3 to R4 clipping appears to be a safe and effective treatment for PPAH. Although postoperative CS was common and higher after R2-bottom clipping, this di

Background/Aims: At present, benefits of surgical resection and appropriate selection criteria in patients affected by both hepatic and pulmonary metastases of colorectal cancer (CRC) are under discussion. Our analysis focused on a surgical series of such patients and our final aim consisted in identifying potential prognostic factors. Methods: Eighty-five patients undergoing resection of both hepatic and pulmonary metastases at 2 Healthcare Institutions from January 1993 to June 2015 were retrospectively reviewed as concerned clinical information, surgical notes and pathological features. Patient, treatment, and outcome variables were analyzed by use of log-rank tests, Cox regression, and Kaplan-Meier methods. Results: Liver turned out as the first site of metastasis in 75% patients, lung in 13% patients, and both sites in 12% patients. Multiple hepatic metastases were detected in 67% patients and pulmonary metastases in 31% patients. Two hundred eighteen surgical interventions were performed (mean 2.56 for each patient). Overall survival (OS) rates at 3-, 5-, and 10-year follow-up from colorectal resection were 94, 79, and 38% respectively. Median OS was 8.31 years. Survival turned out significantly longer for patients with disease-free interval (DFI) exceeding 1 year between first metastasectomy and diagnosis of second metastases and in patients affected by metachronous pulmonary metastases. Conclusions: Surgical resection of both hepatic and pulmonary metastases of CRC represents a safe and effective treatment. It might lead to rewarding long-term survival rates in high selected patients. Shorter DFIs between first metastasectomy and diagnosis of second metastases can determine worse prognoses. In addition, poor outcomes could be predicted also for patients affected by synchronously detected pulmonary CRC metastases, although further confirmatory analyses are strongly required.
