Abstract
Sternal resection and reconstruction is a rare but sometimes challenging procedure due to its profound anatomical and functional implications. For these reasons, an adequate preoperative evaluation is crucial in each patient, especially when we are faced with malignant lesions that sometimes require extensive radical resections, thus demanding an integrated reconstructive strategy that allows stabilizing the chest wall, protecting the underlying mediastinum and minimize resulting deformity. The large number of available reconstruction techniques and the lack of quality studies for their analysis mean that sternal reconstruction depends to a great extent on the consensus of experts or, more frequently, on the simple preference of each surgical team. This article aims to provide an overview of sternal resection and reconstruction. Indications for partial versus total or subtotal sternectomy are suggested and their surgical and oncological outcomes are presented. The use of rigid or semi-rigid prostheses is an ongoing debate, although recent functional data advise reserving rigid reconstructions for extensive defects. Sternectomy for primary tumors or local tumor involvement has a good prognosis with an overall survival of 5 and 10 years: 67% and 58%, respectively, provided that a radical resection with free surgical margins is performed. Breast cancer is the most common secondary sternal tumor, and surgery can offer 5-year overall survival ranging from 20% to 50% provided an R0 resection is achieved, although radical surgery does not appear to decrease rates. of recurrence. Metastases of origin other than the breast give the worst results (less than 40% at 36 months and 0% at 5 years) and although the data available on these cases are limited, the radicality of the resection does not seem to modify the survival or recurrence rates, so a conservative approach is probably more appropriate.

Asia Pac J Clin Oncol 2023; 19:706-714. [PMID: 36707405 DOI: 10.1111/ajco.13934] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Revised: 12/02/2022] [Accepted: 01/07/2023] [Indexed: 01/29/2023]
Abstract
AIM This study was performed to evaluate concordance between clinical and pathologic staging of non-small cell lung cancer (NSCLC) in our hospital network. METHODS We retrospectively reviewed records of 417 patients with NSCLC who received curative surgery and whose pathology was evaluated in our hospital between 2016 and 2021. Cytology, tissue pathology, and associated clinical, surgical, and imaging information were retrieved from hospital digital records. RESULTS The cohort included 214 female and 203 male patients aged 20.6-85.8 years. Median times among staging computed tomography and surgery (105 days [interquartile range (IQR) 77.0-143.0]), positron emission tomography and surgery (78.5 days [IQR 56.0-109.0]), and endobronchial ultrasound-guided transbronchial needle aspiration and surgery (59 days [IQR 42-94]) indicated that Australian guidelines of <42 days between original referral and commencement of treatment were not being met in the majority of cases. Discordance between clinical TNM (cTNM) and pathologic TNM staging was 25.9%, including 18.4% cases that were clinically understaged and two patients with undetected stage IVA disease. cTNM understaging was significantly associated with time between the final staging investigation and surgery (p = .023), pleural (p < .05) and vessel (p < .05) invasion, and diagnosis of high-grade adenocarcinoma (p = .001). CONCLUSION Discordance between clinical and pathologic staging of NSCLC is associated with tumor histopathologic characteristics and treatment delays. Although tumor factors that lead to discordant staging cannot be controlled, reduced time to surgery may have resulted in better outcomes for some patients in this potentially curable lung cancer cohort.

Abstract
AIM To examine the diagnostic performance of different models based on computed tomography (CT) imaging features in differentiating the invasiveness of non-small-cell lung cancer (NSCLC) with multiple pleural contact types. MATERIALS AND METHODS A total of 1,573 patients with NSCLC (tumour size ≤3 cm) were included retrospectively. The clinical and pathological data and preoperative imaging features of these patients were investigated and their relationships with visceral pleural invasion (VPI) were compared statistically. Multivariate logistic regression was used to eliminate confounding factors and establish different predictive models. RESULTS By univariate analysis and multivariable adjustment, surgical history, tumour marker (TM), number of pleural tags, length of solid contact and obstructive inflammation were identified as independent risk predictors of pleural invasiveness (p=0.014, 0.003, <0.001, <0.001, and 0.017, respectively). In the training group, comparison of the diagnostic efficacy between the combined model including these five independent predictors and the image feature model involving the latter three imaging predictors were as follows: sensitivity of 88.9% versus 77% and specificity of 73.5% versus 84.1%, with AUC of 0.868 (95% CI: 0.848-0.886) versus 0.862 (95% CI: 0.842-0.880; p=0.377). In the validation group, the sensitivity and specificity of these two models were as follow: the combined model, 93.5% and 74.3%, the imaging feature model, 77.4% and 81.3%, and their areas under the curve (AUCs) were both 0.884 (95% CI: 0.842-0.919). The best cut-off value of length of solid contact was 7.5 mm (sensitivity 68.9%, specificity 75.5%). CONCLUSIONS The image feature model showed great potential in predicting pleural invasiveness, and had comparable diagnostic efficacy compared with the combined model containing clinical data.

Difference in failure patterns after stereotactic body radiotherapy for lung cancer according to clinical T stage based on 4D computed tomography. Strahlenther Onkol 2022; 199:465-476. [PMID: 36477250 DOI: 10.1007/s00066-022-02030-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 11/08/2022] [Indexed: 12/12/2022]
Abstract
PURPOSE Stereotactic body radiotherapy (SBRT) is a treatment option for early-stage lung cancer. We aimed to examine the differences in failure patterns after SBRT according to the clinical T stage. METHODS A total of 120 patients with early-stage lung cancer (T1-3N0M0) who underwent SBRT were analysed. The clinical stage in patients whose tumours were in contact with the chest wall was confirmed using four-dimensional computed tomography (4D-CT). Local failure, regional node metastasis, and distant metastasis were confirmed from clinical charts. RESULTS Median follow-up time was 27.5 months (range 7-122) after SBRT. Thirteen patients were restaged from clinical T2 with visceral pleural invasion to T3 with chest wall invasion using 4D-CT analysis. Thirty-seven patients developed recurrences. The median progression-free survival (PFS) and overall survival (OS) were 38.1 and 53.8 months, respectively. The 3‑year PFS and OS rates were 50.7% and 60.3%, respectively. A significant difference was observed in PFS according to the clinical T stage (p = 0.001). No significant differences were observed in OS according to the clinical T stage (p = 0.213). The proportion of locoregional failures relative to distant metastasis decreased with progression from T1 to T3. The pleural dissemination rate was significantly higher in T3 tumours than in T1 and T2 tumours (p = 0.010). CONCLUSION Clinical T stage is associated with PFS after SBRT for lung cancer. There were differences in the failure patterns according to T stage. 4D-CT might provide significant information for assessing chest wall invasion associated with unfavourable PFS.

Imaging Assessment of Visceral Pleural Surface Invasion by Lung Cancer: Comparison of CT and Contrast-Enhanced Radial T1-Weighted Gradient Echo 3-Tesla MRI. Korean J Radiol 2021; 22:829-839. [PMID: 33686817 PMCID: PMC8076827 DOI: 10.3348/kjr.2020.0955] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 11/10/2020] [Accepted: 11/28/2020] [Indexed: 12/25/2022] Open
Abstract
Objective To compare the diagnostic performance of contrast-enhanced radial T1-weighted gradient-echo 3-tesla (3T) magnetic resonance imaging (MRI) and computed tomography (CT) for the detection of visceral pleural surface invasion (VPSI). Visceral pleural invasion by non-small-cell lung cancer (NSCLC) can be classified into two types: PL1 (without VPSI), invasion of the elastic layer of the visceral pleura without reaching the visceral pleural surface, and PL2 (with VPSI), full invasion of the visceral pleura. Materials and Methods Thirty-three patients with pathologically confirmed VPSI by NSCLC were retrospectively reviewed. Multidetector CT and contrast-enhanced 3T MRI with a free-breathing radial three-dimensional fat-suppressed volumetric interpolated breath-hold examination (VIBE) pulse sequence were compared in terms of the length of contact, angle of mass margin, and arch distance-to-maximum tumor diameter ratio. Supplemental evaluation of the tumor-pleura interface (smooth versus irregular) could only be performed with MRI (not discernible on CT). Results At the tumor-pleura interface, radial VIBE MRI revealed a smooth margin in 20 of 21 patients without VPSI and an irregular margin in 10 of 12 patients with VPSI, yielding an accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and F-score for VPSI detection of 91%, 83%, 95%, 91%, 91%, and 87%, respectively. The McNemar test and receiver operating characteristics curve analysis revealed no significant differences between the diagnostic accuracies of CT and MRI for evaluating the contact length, angle of mass margin, or arch distance-to-maximum tumor diameter ratio as predictors of VPSI. Conclusion The diagnostic performance of contrast-enhanced radial T1-weighted gradient-echo 3T MRI and CT were equal in terms of the contact length, angle of mass margin, and arch distance-to-maximum tumor diameter ratio. The advantage of MRI is its clear depiction of the tumor-pleura interface margin, facilitating VPSI detection.

Abstract
Background The risk factors for the development of chest wall invasion (CWI) in non-small cell lung cancer (NSCLC) patients are unclear. If the risk factors for the development of CWI can be clarified, surgical treatment might be able to be performed before CWI development, thus improving the prognosis. Methods In the present study, we enrolled patients who received surgery for NSCLC between January 2008 and December 2019 with available data on the maximum standardized uptake value (SUVmax) on positron emission tomography (PET) with lesions adjacent to the visceral pleura. Furthermore, the preoperative white blood cell (WBC) count, the preoperative neutrophil-to-lymphocyte ratio (NLR), platelet (Plt) count, levels of lactate dehydrogenase (LDH) and C-reactive protein (CRP) were analyzed as predictive factors of CWI. Results The relationships between CWI and clinicopathological variables were analyzed, and there were significant differences between patients with and without CWI in the age (P=0.02), maximum tumor diameter on computed tomography (CT) (P<0.01), diameter of tumors adjacent to the visceral pleura (Pmax) (P<0.01), SUVmax (P<0.01), maximum tumor diameter on a pathological examination (P<0.01), WBC count (P=0.03), Plt count (P=0.04), and levels of LDH (P<0.01) and CRP (P=0.01). Logistic regression analyses of the risk factors related to CWI showed that the age (P=0.02), Pmax (P=0.02), SUVmax (P=0.01), and LDH (P<0.01) were significant risk factors. Conclusions The age, Pmax, SUVmax, and LDH levels might be associated with CWI.

Abstract
BACKGROUND Although the use of the uniportal thoracoscopic technique has spread exponentially recently, a comparison of nonintubated and intubated uniportal thoracoscopic segmentectomies for lung tumors has not been reported. We aimed to compare the feasibility, safety, and short-term postoperative outcomes between the 2 methods. METHODS From January 2014 to June 2019 we retrospectively reviewed 185 consecutive patients with lung tumors who underwent uniportal thoracoscopic segmentectomy at our institute. A body mass index of ≥25 kg/m2 was considered a contraindication for the nonintubated anesthetic approach. For the remaining cases the anesthetic approach was made at the discretion of each individual anesthesiologist. A propensity-matched analysis incorporating sex and body mass index was used to compare the clinical outcomes of the nonintubated and intubated groups. RESULTS Fifty patients (27.0%) underwent the procedure with the nonintubated anesthetic approach. The nonintubated group was more likely to be female (P < .001) and with a lower body mass index (P < .001). Other clinical features showed no significant difference. There was no significant difference between the 2 groups in the type of segmentectomy according to the difficulty classification system. After propensity matching 43 matched patients in each group were included. Anesthetic induction duration (12.0 vs 15.3 minutes, P = .014) was shorter in the nonintubated group. No other significant differences in perioperative, postoperative, and anesthetic results were noted between the 2 matched groups. CONCLUSIONS The nonintubated anesthetic approach can be a safe and feasible alternative to intubated uniportal thoracoscopic segmentectomy.

Abstract
Introduction. Preoperative detection of pleural invasion in lung cancer patients is key to curative surgical treatment. We tried to predict pleural invasion in non-small-cell lung cancer patients with <100 ml pleural fluid. Methods Patients admitted from August 1, 2011, to December 31, 2018, were retrospectively retrieved. Records of serum and imaging markers were analyzed. Results Among 7004 patients who received surgery, 43 cases with <100 ml pleural fluid who had pleural invasion were included, and another 108 cases without pleural invasion were enrolled as controls. There were no differences in squamous cell carcinoma antigen (SCC) or neuron-specific enolase (NSE) values between the pleural invasion and noninvasion groups (p = 0.30 and 0.14, respectively), but there were significant differences in carcinoembryonic antigen (CEA) and cytokeratin 19 fragment (CYFRA21-1) values (p = 0.30 and 0.14, respectively), but there were significant differences in carcinoembryonic antigen (CEA) and cytokeratin 19 fragment (CYFRA21-1) values (p = 0.30 and 0.14, respectively), but there were significant differences in carcinoembryonic antigen (CEA) and cytokeratin 19 fragment (CYFRA21-1) values (p = 0.30 and 0.14, respectively), but there were significant differences in carcinoembryonic antigen (CEA) and cytokeratin 19 fragment (CYFRA21-1) values (p = 0.30 and 0.14, respectively), but there were significant differences in carcinoembryonic antigen (CEA) and cytokeratin 19 fragment (CYFRA21-1) values (p = 0.30 and 0.14, respectively), but there were significant differences in carcinoembryonic antigen (CEA) and cytokeratin 19 fragment (CYFRA21-1) values (p = 0.30 and 0.14, respectively), but there were significant differences in carcinoembryonic antigen (CEA) and cytokeratin 19 fragment (CYFRA21-1) values (. Conclusions Serum CEA and CYFRA21-1, location of original lung cancer (right mid lobe), maximum diameter, CT-detectable pleural fluid, pleural sign by CT, and PET/CT-predicted pleural invasion were good markers for the prediction of pleural invasion in non-small-cell lung cancer patients.

Ann Surg Oncol 2019; 27:703-715.

Abstract
BACKGROUND The optimal surgical method for cT1N0 lung adenocarcinoma remains controversial. OBJECTIVE The aim of this study was to evaluate the differences in clinical outcomes of sublobar resection and lobectomy for cT1N0 lung adenocarcinoma patients. METHODS We included 1035 consecutive patients with cT1N0 lung adenocarcinoma who underwent surgery at our institute from January 2011 to December 2016. The surgical approach, either sublobar resection or lobectomy, was determined at the discretion of each surgeon. A propensity-matched analysis incorporating total tumor diameter, solid component diameter, consolidation-to-tumor (C/T) ratio, and performance status was used to compare the clinical outcomes of the sublobar resection and lobectomy groups. RESULTS Sublobar resection and lobectomy were performed for 604 (58.4%; wedge resection/segmentectomy: 470/134) and 431 (41.6%) patients, respectively. Patients in the sublobar resection group had smaller total tumor diameters, smaller solid component diameters, lower C/T ratios, and better performance status. More lymph nodes were dissected in the lobectomy group. Patients in the sublobar resection group had better perioperative outcomes. A multivariable analysis revealed that the solid component diameter and serum carcinoembryonic antigen level are independent risk factors for tumor recurrence. After propensity matching, 284 paired patients in each group were included. No differences in overall survival (OS; p = 0.424) or disease-free survival (DFS; p = 0.296) were noted between the two matched groups. CONCLUSIONS Sublobar resection is not inferior to lobectomy regarding both DFS and OS for cT1N0 lung adenocarcinoma patients. Sublobar resection may be a feasible surgical method for cT1N0 lung adenocarcinoma.
