RESUMO
INTRODUCTION: The 'surgically performed' continuous superficial serratus anterior plane block (continuous s-SAPB) was never described before in uniportal video-assisted thoracic surgery (uniportal VATS) surgery. The aim of the study was to evaluate the safety and efficacy of the technique. PATIENTS AND METHODS: Between March 2022 and April 2023, 50 patients, undergone uniportal VATS surgery at our thoracic surgery department, were scheduled for a surgically performed continuous s-SAPB as post-operative analgesia protocol. RESULTS: The mean execution time for the block was 3.92 ± 2.56 min. Ten patients (20%) required morphine for a visual analogue scale (VAS) score >4 immediately after surgery. The recorded VAS score at chest tube removal was 1.87 ± 1.41, whereas 2 h after the manoeuvre was 0.42 ± 0.72. No complication related to block insertion was recorded. The onset of chronic pain was observed in a total of 2 patients (4%). CONCLUSIONS: The surgically performed continuous s-SAPB in uniportal VATS seems to be safe and easy to perform, and it provides a satisfactory analgesic effect.
RESUMO
OBJECTIVES: The study aimed to assess the feasibility of radical surgical treatment for selected bone-oligometastatic non-small cell lung cancer (NSCLC) patients and to identify prognostic factors associated with survival. MATERIALS AND METHODS: The clinical records of 27 patients with bone synchronous oligometastatic NSCLC were retrospectively analyzed. RESULTS: Thirteen (48.1%) bone metastases were treated by surgery and 14 (51.9%) by local radiotherapy. Eighteen (66.7%) patients underwent induction chemotherapy before lung surgery, and 3 (11.1%) concurrent radiotherapy. Pulmonary surgery was a major lung resection in 23 (85.2%) cases. Intraoperative and 30-days mortality was null. Only one major (ARDS) and 10 (37.04%) mild complications (like air leakage, arrhythmia, and mucus retention) were recorded. 1-year and 5-years OS from the diagnosis and 1-year, 3- years disease-free survival (DFS) were 96%, 38%, and 66%, 30%, respectively. After stepwise Cox regression analysis, local recurrence (p = 0.05) and metachronous metastases (p = 0.04) maintained their independent prognostic value as overall survival negative determinants. Nodal upstaging (p = 0.04) and nonsurgical treatment of bone lesion (p = 0.03) turned out to be independent risk factors for shorter DFS; the vertebral localization of bone metastases showed only a remarkable trend towards significance (p = 0.06) as a risk factor for a worse DFS. CONCLUSIONS: In selected patients, surgical treatment of primary NSCLC and bone synchronous metastasis seems to be safe and feasible and rewarding survivals may be expected.

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: Data on high-flow nasal oxygen after thoracic surgery are limited and confined to the comparison with low-flow oxygen. Different from low-flow oxygen, Venturi masks provide higher gas flow at a predetermined fraction of inspired oxygen (FiO2). We conducted a randomized trial to determine whether preemptive high-flow nasal oxygen reduces the incidence of postoperative hypoxemia after lung resection, as compared to Venturi mask oxygen therapy. METHODS: In this single-center, randomized trial conducted in a teaching hospital in Italy, consecutive adult patients undergoing thoracotomic lung resection, who were not on long-term oxygen therapy, were randomly assigned to receive high-flow nasal or Venturi mask oxygen after extubation continuously for two postoperative days. The primary outcome was the incidence of postoperative hypoxemia (i.e., ratio of the partial pressure of arterial oxygen to FiO2 (PaO2/FiO2) lower than 300 mmHg) within four postoperative days. RESULTS: Between September 2015 and April 2018, 96 patients were enrolled; 95 patients were analyzed (47 in high-flow group and 48 in Venturi mask group). In both groups, 38 patients (81% in the high-flow group and 79% in the Venturi mask group) developed postoperative hypoxemia, with an unadjusted odds ratio (OR) for the high-flow group of 1.11 [95% confidence interval (CI) 0.41-3] (p = 0.84). No inter-group differences were found in the degree of dyspnea nor in the proportion of patients needing oxygen therapy after treatment discontinuation (OR 1.34 [95% CI 0.60-3]), experiencing pulmonary complications (OR 1.29 [95% CI 0.51-3.25]) or requiring ventilatory support (OR 0.67 [95% CI 0.11-4.18]). Post hoc analyses revealed that PaO2/FiO2 during the study was not different between groups (p = 0.92), but patients receiving high-flow nasal oxygen had lower arterial pressure of carbon dioxide, with a mean inter-group difference of 2 mmHg [95% CI 0.5-3.4] (p = 0.009), and were burdened by a lower risk of postoperative hypercapnia (adjusted OR 0.18 [95% CI 0.06-0.54], p = 0.002). CONCLUSIONS: When compared to Venturi mask after thoracotomic lung resection, preemptive high-flow nasal oxygen did not reduce the incidence of postoperative hypoxemia nor improved other analyzed outcomes. Further adequately powered investigations in this setting are warranted to establish whether high-flow nasal oxygen may yield clinical benefit on carbon dioxide clearance.

BACKGROUND: The aim of this study was to identify prognostic factors in patients affected by non-small cell lung cancer (NSCLC) with chest wall (CW) involvement, analyzing different strategies of treatment and surgical approaches. METHODS: Records of 59 patients affected by NSCLC with CW involvement underwent surgery were retrospectively reviewed, from January 2000 to March 2013. RESULTS: Induction therapy was administered to 18 (30.5%) patients while adjuvant treatment to 36 (61.0%). In 36 (61%) patients, lung resection was associated only with a parietal pleural resection while in 23 (39%) with CW en-bloc resection. Overall 5-year survival was 34%. Prognostic factors were evaluated in the 51 (86.4%) completely resected (R0) patients.Five-year survival was 60% in patients undergoing induction therapy followed by surgery and 24% in those who underwent surgery as first treatment (p = 0.11). Five-year survival was better in the neoadjuvant group than that in the surgery group in IIB (T3N0) p-stage (100 vs 28%, p = 0.03), while in the IIIA (T3N1-2,T4N0) p-stage it was of 25 vs 0%, respectively (p = 0.53).No 5-year survival difference was found in case of parietal pleural resection versus CW en-bloc resection (p = 0.27) and in case of only parietal pleural involvement versus soft tissue (p = 0.78).In case of incomplete resection (R1), patients undergoing adjuvant radiotherapy had better 2-year survival than patients untreated: 60% vs 0% (p = 0.025). CONCLUSIONS: Type of surgical resection and the deep of infiltration of disease do not influence survival in this subset of patients. Integrated treatments seem to be suitable: neoadjuvant therapies ensure a better survival rate than surgery alone in IIB and IIIA patients, instead adjuvant radiotherapy proves a fundamental option in incomplete resections.

BACKGROUND: Digital devices could help clinical practice measuring the air leak, but their role is still debated. Aim of this study is to test advantages using these devices. METHODS: From June 2012 to May 2015, we enrolled 95 patients undergoing lobectomy or wedge resection in a prospective randomized trial. Patients were divided into two groups: group D (digital, 50 patients) evaluated with digital device and group E (empirical, 45 patients) evaluated with water seal. Logistic regression analysis and receiver operating characteristic (ROC) curve analysis were used to select and assess predictors of persistent air leak. In group D, chest drain was removed if the air leak was absent or < 0.5 L/h for 12 consecutive hours and in group E if clinical signs of air leak were absent. RESULTS: Mean hospitalization and mean chest tube stay was 6.0 ± 3.3 and 4.4 ± 3.2 days, respectively, prolonged air leak occurred in nine (8%). Hospitalization was 5.8 ± 2.5 versus 6.2 ± 4.2 days (p = 0.5), while mean chest tube stay was 4.1 ± 2.0 versus 4.6 ± 3.5 days (p = 0.4) in group D and group E, respectively. Clamping test was needed in one patient in group D and in seven in group E (p = 0.019). At multivariate analysis, heart disease (p < 0.0001), lobectomy (p < 0.0001), fused fissure (p < 0.0001), and air leakage in first postoperative (p.o.) day were predictors of persistent air leak (AUC on the ROC curve of 69.7%, sensibility: 77.8%). In group D, an air leak value > 0.2 L/h with spikes over 0.5 L/h in third p.o. was predictive of persistent air leak, with chest tube duration of 7.73 ± 5.20 versus 4.32 ± 1.33 days (AUC: 83%, sensitivity: 80%, p < 0.0001). CONCLUSION: In our experience, digital devices reduced observer variability and mistakes in chest tube management, thus identifying patients at risk for prolonged air leak.

BACKGROUND: We report our experience and outcomes about the management of Askin's tumors [AT], which are rare primitive neuroectodermal tumors (PNETs) that develop within the soft tissue of the thoracopulmonary region, typically in children and adolescents. METHODS: We retrospectively analyzed the charts of 9 patients affected by AT (aged 6-15 years), treated at the Paediatric Oncology Unit of Gemelli University Hospital in Rome between January 2001 and December 2016. RESULTS: All nine patients underwent to biopsy followed by neoadjuvant chemotherapy. At the end of the neoadjuvant chemotherapy, they underwent to surgical removal of the residual tumor. Five patients with positive tumor margins and/or necrosis< 90% received local radiotherapy. Two patients with metastasis received an intensified treatment, with the addition of high dose adjuvant chemotherapy followed by peripheral blood stem cells rescue. No statistically significant correlation was found between outcome and gender; the presence of any metastasis and the radiotherapy. The overall survival was 65.14 months (95% confidence interval [95%CI], 45.81-84.48), and the 5 years survival was 60%, at a median follow-up of 53.1 months. CONCLUSION: Our study confirms that a multimodal treatment with surgery, chemotherapy, and radiotherapy may increase the survival in AT pediatric patients.

RESUMO
Teratomas are rare germ cell tumors derived from multiple germinal cell layers. Thyroid teratomas, specifically, are exceptionally uncommon and present unique diagnostic and therapeutic challenges. Here, we report a case of cervico-mediastinal thyroid teratoma, highlighting diagnostic difficulties and surgical management. A 37-year-old woman presented with right lateral cervical swelling, leading to radiological imaging suggesting a thymic teratoma. However, cytology indicated a colloid cyst. Surgical removal was performed, revealing a mixed-type teratoma originating from the thyroid gland. Thyroid teratomas pose diagnostic and therapeutic challenges due to their rarity and complex nature. Further research is needed to establish standardized guidelines for their management.
RESUMO
OBJECTIVES: Aim of this study is to identify the factors that may influence the lymphadenectomy during VATS anatomical lung resection with particular interest on operator experience. MATERIALS AND METHODS: Clinical and pathological data from the prospective VATS Italian nationwide registry were reviewed and analysed. Patients with incomplete data regarding tumor and surgical characteristics, GGO, or with distant metastases were excluded. Patients clinical data, tumor characteristics, operation information and surgeon experience were collected and compared to resected lymph nodes number (#RN), resected N2 nodes number (#N2RN) and resected N2 stations number. A multivariable model was built using logistic regression analysis. Surgeon experience was categorized considering the number of VATS major anatomical resection and years after residency. RESULTS: The final analysis was conducted on 3727 patients. The median #RN and #N2RN were 11 (1-51) and 5 (0-41). Regarding the analysed outcomes, #N2RN > 6 resulted in 1812 (48.8%)cases, #RN > 10 in 2124 (57.0%)cases and more than 3 N2 stations were harvested in 1447 (38.8%)patients. First operator experience with number of VATS lobectomies>50 (p < 0.001), operator seniority after residency5-10years (p < 0.001), cTNM II/III(p = 0.017), lobectomy/bilobectomy vs segmentectomy (p < 0.001), and upper/middle lobe tumor location (p < 0.005)resulted significantly associated to #N2RN > 6 at the multivariable analysis. First operator experience with number of VATS lobectomies>50 (p < 0.001), operator seniority after residency5-10years (p < 0.001) and lobectomy/bilobectomy (p < 0.001) resulted significantly associated to #RN > 10 at the multivariable analysis. CONCLUSIONS: Our study showed that lymphadenectomy during VATS lobectomy is influenced by tumor factors such as cTstage and tumor location but also by operator experience, with a higher number of resected lymph nodes in surgeons with a high number of VATS procedures and years after residency compared to surgeons with less experience.

BACKGROUND: Despite recent improvement in preoperative staging, nodal and mediastinal upstaging occur in about 5% to 15% of cN0 patients. Different clinical and tumor characteristics are associated with upstaging, whereas the role of the surgeon's experience is not well evaluated. This study aimed to investigate if operator experience might influence nodal upstaging during video-assisted thoracic surgery anatomical lung resection. METHODS: Clinical and pathological data from the prospective video-assisted thoracic surgery Italian nationwide registry were reviewed and analyzed. Patients with incomplete data about tumor and surgical characteristics, ground glass opacities tumors, cN2 to 3, and M+ were excluded. Clinical data, tumor characteristics, and surgeon experience were correlated to nodal and mediastinal (N2) upstaging using Pearson's χ2 statistic or Fisher exact test for categorical variables and Mann-Whitney U and t tests for quantitative variables. A multivariable model was built using logistic regression analysis. Surgeon experience was categorized considering the number of video-assisted thoracic surgery major anatomical resections and years after residency. RESULTS: Final analysis was conducted on 3,319 cN0 patients for nodal upstaging and 3,471 cN0N1 patients for N2 upstaging. Clinical tumor-nodes-metastasis stage was stage I in 2,846 (81.9%) patients, stage II in 533 (15.3%), and stage III (cT3N1) in 92 (2.8%). Nodal upstaging occurred in 489 (13.1%) patients, whereas N2 upstaging occurred in 229 (6.1%) patients. Years after residency (P = .60 for nodal, P = .13 for N2 upstaging) and a number of video-assisted thoracic surgery procedures(P = .49 for nodal, P = .72 for nodal upstaging) did not correlate with upstaging. Multivariable analysis confirmed cT-dimension (P = .001), solid nodules (P < .001), clinical tumor-nodes-metastasis (P < .001) and maximum standardized uptake values (P < .001) as factors independently correlated to nodal upstaging, whereas cT-dimension (P = .005), clinical tumor-nodes-metastasis (P < .001) and maximum standardized uptake values (P = .028) resulted independently correlated to N2 upstaging. CONCLUSION: Our study showed that surgeon experience did not influence nodal and mediastinal upstaging during -assisted thoracic surgery anatomical resection, whereas cT-dimension, clinical tumor-nodes-metastasis, and maximum standardized uptake values resulted independently correlated to nodal and mediastinal upstaging.

Thymic cysts are rare, radiological diagnosis is often incidental, and cysts seldom assume clinical relevance for symptoms of compression. Thymoma were occasionally found inside both complex and simple thymic cysts. Given the challenges in accurately clinical diagnosing and since the occasionally discovering of thymoma inside both complex and simple thymic cysts, the management of thymic cysts remains controversial. Advancements in surgical tools such as robotics, applied to thymic conditions, could potentially transform the approach to thymic cysts. We report one the largest multicentric series of thymic cysts surgically treated with robotic approach, focusing on preoperative findings and surgical results. Cases were gathered from three Italian thoracic surgery centers with homogeneous clinical practice, significant experience in thymic neoplasms, and thoracic robotic skilled. Surgical intervention was indicated for patients with radiological diagnosis of thymic cysts under the following circumstances: the presence of symptoms, concurrent myasthenia gravis, cysts growing in follow-up, and the complexity of the cyst with suspicion of neoplasm. Data were collected and matched according to postoperative and pathological features to identify potential prognostic factors. Population include 57 patients, 29/28 male/female ratio with mean age of 59.46 ± 11.67 years. The average size of the thymic cysts was 29.14 ± 24.53 ranged between 3 and 150 mm. All patients undergone CT scan and mean of values of density was 25.82 ± 11-82 Hounsfield. Surgical procedures were robotic approach in all case including total/extended thymectomy 35 (61.4%) and cyst resection/partial thymectomy 22 (38.6%). There were no mortality or recurrence. Major complications rate was 5.3%. No correlations were observed between preoperative features and complication. Pathological examination revealed microfoci of thymic tumor in four cases. Robot-assisted surgery for thymic cysts showed excellent early clinical outcomes with low rate of postoperative complications also in case of large lesion. Thymic cysts should not be underestimated due to the risk of coexistent thymic neoplasm.
RESUMO
To increase the neurological results in patients older than 65 years with myasthenia gravis after thymectomy, we retrospectively analysed this outcome in a large bicentric cohort of patients with myasthenia gravis (MG)years, for which surgery was indicated for a concurrent thymoma. From 1/2000 to 2/2022, 502 patients underwent thymectomy for thymic epithelial tumours (TETs) in two high-volume Institutions (167aged more than 65 years). Among them, 66 patients were affected by TET and MG, representing our final study group. The mean age for MG onset was 68.3 ± 6 years.At surgery, the Osserman score 2 was the most diffuse in our cohort (43, 65.1%), followed by 1 (20, 30.3%). In 11 cases, the MG diagnosis coincided with thymoma diagnosis. In the other cases, the interval between MG diagnosis and surgery was 1.7 years ± 1.9. The most common surgical approach was sternotomy (41,62.1%), followed by RATS (14,21.2%). The most frequent TNM stage was T1N0 (75.7%) and most patients had WHO type-B tumour. After radical thymectomy, 58 patients (88%) reported a significant neurological improvement. According to MGFA-PIS, after surgery we had 4 (6%) complete stable remission, 11 (16.7%) pharmacological remission, 43 (65.2%) minimal manifestation, 2 (3%) worsening/death for MG, and 5 (7.6%) unchanged. No association was found between neurological outcome and age of MG onset, kind of pharmacological therapy before surgery, surgical approach (sternotomy vs others), tumour dimension, the ITMIG stage and the preoperative Osserman score. For MG and thymoma-afftected patients over 65 years, thymectomy seems to be an effective treatment to improve neurological symptoms. We suggest to set up clinical trials to explore the neurological efficacy of mini-invasive thymectomy in clinically selected MG patients aged over 65 years.
RESUMO
BACKGROUND: The advantages of video-assisted thoracic surgery (VATS) are well-recognized in several studies. However, in the cases of advanced lung cancer after neoadjuvant chemotherapy (nCT), the role of VATS is still questionable, with concerns about safety, technical feasibility, and oncological completeness. The aim of this study was to assess the impact of nCT on patients who had undergone uniportal VATS (U-VATS) anatomic lung resections for lung cancer, by comparing the short-term outcomes of patients after nCT with case-matched counterparts (treated by surgery alone). METHODS: We performed a retrospective, comparative study enrolling 927 patients (nCT: 60; non-nCT:867) who underwent U-VATS anatomic lung resections from 2014 to 2020 in two centers. Data were collected in a shared database with standardized variables' definition. Propensity score matching using 15 baseline preoperative patients' characteristics was performed in order to minimize selection-confounding factors between the two groups, which then were directly compared in terms of perioperative outcomes. RESULTS: After propensity score matching, two groups of 60 patients had been defined. The nCT-group had a higher conversion rate compared to the control group (13.3% vs. 0%, p = 0.003) without an increase in operation time or cardiopulmonary complications. In addition, no differences between the two groups were recorded in terms of prolonged air leaks, length of stay, and readmission. CONCLUSIONS: U-VATS after nCT is a feasible approach, showing a similar rate of cardiopulmonary complications and length of stay when compared with the control group. However, it remains a challenging surgery due to its great technical complexity as well as the clinical status of the patients.
RESUMO
OBJECTIVE: The aim of this study is to describe characteristics and survival outcome of patients who underwent surgical treatment for distant thymoma relapse according to the definition of the International Thymic Malignancy Interest Group. METHODS: Data of patients affected by thymoma recurrence from four different institutions were collected and retrospectively reviewed. Patients with locoregional metastases who underwent nonsurgical therapies and with incomplete data on follow-up were excluded. According to the International Thymic Malignancy Interest Group distant recurrence definition, patients with recurrence due to hematogenic localization were included. Clinical and pathologic characteristics were described using descriptive statistics, whereas survival outcome was calculated using Kaplan-Meier curves and Cox regression analysis. RESULTS: The analysis was conducted on 40 patients. A single localization was present in 13 patients, the relapse was intrathoracic in 28 cases (70%), and lung involvement was found in 26 cases. The liver was operated in seven cases, whereas other kinds of abdominal involvement were detected in eight cases. Adjuvant treatment was administered in 22 cases (55%).Five- and 10-year overall survival (OS) were 67% and 30%, respectively. Univariable analysis identified as significant favorable factor a low-grade histology (A, B1, B2): five-year OS at 92.3% versus 53.3% in high-grade (B3-C) (p = 0.035). Site of recurrence and number of localization did not influence the prognosis, but in patients with adjuvant therapy administration, there was a survival advantage also if not statistically significant: five-year OS 84.8% versus 54.5% in patients without adjuvant therapy (p = 0.101).Multivariable analysis confirmed as independent prognostic factor low-grade histology: hazard ratio = 0.176, 95% confidence interval 0.042-0.744, p = 0.018. CONCLUSIONS: Our study revealed a good survival outcome in patients who underwent surgery for distant thymoma recurrence, independently from the number and site of the relapse localization. Patients with A, B1, or B2 histology presented a significantly better survival than patients with B3-C.

BACKGROUND: To evaluate the analgesic efficacy of continuous erector spinae plane block(c-ESPB) and serratus anterior plane block(c-SAPB) versus the intercostal nerve block (ICNB) in Uniportal-VATS in terms of pain control, drug consumption, and complications. METHODS: Ninety-three consecutive patients, undergone one of the three peripheral nerve blocks after Uniportal-VATS, were prospectively enrolled. A 1:1 propensity score matching was used to minimize bias. RESULTS: C-ESPB and c-SAPB groups had no difference in morphine request upon awakening compared to ICNB. A higher VAS-score was recorded in c-ESPB compared to ICNB in the first 12 h after surgery. A significantly lower consumption of paracetamol in II postoperative day (p.o.d.) and tramadol in I and II p.o.d. was recorded in the c-ESPB group compared to the ICNB group. A higher dynamic VAS score was recorded at 24 h and 48 h in the ICNB group compared to the c-SAPB. No difference was found in safety, VAS-score and drug consumption between c-ESPB and c-SAPB at any given time, except for a higher tramadol request in c-SAPB in II p.o.d. CONCLUSIONS: C-ESPB and c-SAPB appear to have the same safety and analgesic efficacy when compared between them and to ICNB in Uniportal-VATS approach. C-ESPB showed a delayed onset of analgesic effect and a lower postoperative drug consumption compared to ICNB.
RESUMO
Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related mortality worldwide. Notably, the incidence of lung cancer among never-smokers, predominantly women, has been rising in recent years. Among the various implicated risk factors, human papilloma virus (HPV) may play a role in the development of NSCLC in a certain subset of patients. The prevalence of high-risk HPV-DNA within human neoplastic lung cells varies across the world; however, the carcinogenetic role of HPV in NSCLC has not been completely understood. Bloodstream could be one of the routes of transmission from infected sites to the lungs, along with oral (through unprotected oral sex) and airborne transmission. Previous studies reported an elevated risk of NSCLC in patients with prior HPV-related tumors, such as cervical, laryngeal, or oropharyngeal cancer, with better prognosis for HPV-positive lung cancers compared to negative forms. On the other hand, 16% of NSCLC patients present circulating HPV-DNA in peripheral blood along with miRNAs expression. Typically, these patients have a poorly differentiated NSCLC, often diagnosed at an advanced stage. However, HPV-positive lung cancers seem to have a better response to target therapies (EGFR) and immune checkpoint inhibitors and show an increased sensitivity to platinum-based treatments. This review summarizes the current evidence regarding the role of HPV in NSCLC development, especially among patients with a history of HPV-related cancers. It also examines the diagnostic and prognostic significance of HPV, investigating new future perspectives to enhance cancer screening, diagnostic protocols, and the development of more targeted therapies tailored to specific cohorts of NSCLC patients with confirmed HPV infection.
RESUMO
OBJECTIVES: The aim of this study is to evaluate if the efficacy and safety of chest tube placement are influenced by the level of intercostal space insertion (uniportal VATS vs. biportal VATS) or by the type of drain employed (standard vs. smart coaxial drain). METHODS: Data on patients who underwent either uniportal or biportal VATS upper lobectomies with lymphadenectomy were prospectively collected in three European centers. The uniportal VATS group with a 28 Fr standard chest tube (U-VATS standard) was compared with the uniportal VATS group with a 28 Fr smart drain (U-VATS smart), and U-VATS smart was also compared with biportal VATS with a 28 Fr smart drain inserted in the VIII intercostal space (Bi-VATS smart). RESULTS: When comparing the U-VATS standard group with the U-VATS smart, a higher fluid output was recorded in the U-VATS smart (p: 0.004) in the III post-operative day (p.o.) and overall (p: 0.027), with a lower 90-day re-admission in the U-VATS smart (p: 0.04). The Bi-VATS smart group compared to U-VATS smart showed a higher fluid output in the I p.o. (p < 0.001), with no difference in total fluid amount or hospitalization. The Bi-VATS smart recorded a lower incidence (p < 0.001) of residual pleural space or effusion (p: 0.004) at chest X-rays prior to drain removal but a higher level of pain and chronic intercostal neuralgia (p: 0.03). CONCLUSIONS: Chest tube insertion through the same incision space in uniportal VATS seems to be safe and effective. Smart drains can improve the fluid output in uniportal VATS, as if the drainage were inserted in a lower space (i.e., biportal VATS), but with less discomfort.
RESUMO
BACKGROUND: Completion lobectomy (CL) following a prior resection in the same lobe may be complicated by severe pleural or hilar adhesions. The role of uniportal video-assisted thoracoscopic surgery (U-VATS) has never been evaluated in this setting. METHODS: Data were collected from two Italian centers. Between 2015 and 2022, 122 patients (60 men and 62 women, median age 67.7 ± 8.913) underwent U-VATS CL at least 4 weeks after previous lung surgery. RESULTS: Twenty-eight (22.9%) patients were affected by chronic obstructive pulmonary disease (COPD) and twenty-five (20.4%) were active smokers. Among the cohort, the initial surgery was performed using U-VATS in 103 (84.4%) patients, triportal-VATS in 8 (6.6%), and thoracotomy in 11 (9.0%). Anatomical segmentectomy was the initial surgery in 46 (37.7%) patients, while hilar lymphadenectomy was performed in 16 (13.1%) cases. CL was performed on 110 (90.2%) patients, segmentectomy on 10 (8.2%), and completion pneumonectomy on 2 (1.6%). Upon reoperation, moderate pleural adhesions were observed in 38 (31.1%) patients, with 2 (1.6%) exhibiting strong adhesions. Moderate hilar adhesions were found in 18 (14.8%) patients and strong adhesions in 11 (9.0%). The median operative time was 203.93 ± 74.4 min. In four (3.3%) patients, PA taping was performed. One patient experienced intraoperative bleeding that did not require conversion to thoracotomy. Conversion to thoracotomy was necessary in three (2.5%) patients. The median postoperative drainage stay and postoperative hospital stay were 5.67 ± 4.44 and 5.52 ± 2.66 days, respectively. Postoperative complications occurred in 34 (27.9%) patients. Thirty-day mortality was null. Histology was the only factor found to negatively influence intraoperative outcomes (p = 0.000). Factors identified as negatively impacting postoperative outcomes at univariate analyses were male sex (p = 0.003), age > 60 years (p = 0.003), COPD (p = 0.014), previous thoracotomy (p = 0.000), previous S2 segmentectomy (p = 0.001), previous S8 segmentectomy (p = 0.008), and interval between operations > 5 weeks (p= 0.005). In multivariate analysis, only COPD confirmed its role as an independent risk factor for postoperative complications (HR: 5.12, 95% CI (1.07-24.50), p = 0.04). CONCLUSIONS: U-VATS CL seems feasible and safe after wedge resection and anatomical segmentectomy.
