Front Oncol 2024; 14:1392213. [PMID: 39070140 PMCID: PMC11273236 DOI: 10.3389/fonc.2024.1392213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Accepted: 06/10/2024] [Indexed: 07/30/2024] Open
Abstract
Background Through preoperative localization, surgeons can easily locate ground glass nodules (GGNs) and effectively control the extent of resection. Therefore, it is necessary to choose an appropriate puncture positioning method. The purpose of this study was to evaluate the effectiveness and safety of medical glue and positioning hooks in the preoperative positioning of GGNs and to provide a reference for clinical selection. Methods From March 30, 2020 to June 13, 2022, a total of 859 patients with a CT diagnosis of GGNs requiring surgical resection were included in our study at the hospital. Among them, 21 patients who either opted out or could not undergo preoperative localization for various reasons were excluded. Additionally, 475 patients who underwent preoperative localization using medical glue and 363 patients who underwent preoperative localization through positioning hooks were also excluded. We conducted statistical analyses on the baseline data, success rates, complications, and pathological results of the remaining patients. The success rates, complication rates, and pathological results were compared between the two groups-those who received medical glue localization and those who received positioning hook localization. Results There was no statistically significant difference between the two groups of patients in terms of age, body mass index, smoking history, location of the nodule, distance of the nodule from the pleura, or postoperative pathological results (P > 0.05). The success rate of medical glue and positioning hooks was 100%. The complication rates of medical glue and positioning hooks during single nodule positioning were 39.18% and 23.18%, respectively, which were significantly different (p < 0.001); the complication rates during multiple nodule positioning were 49.15% and 49.18%, respectively, with no statistically significant differences (p > 0.05). In addition, the method of positioning and the clinical characteristics of the patients were not found to be independent risk factors for the occurrence of complications. The detection rate of pulmonary nodules also showed some positive correlation with the spread of COVID-19 during the 2020-2022 period when COVID-19 was prevalent. Conclusion When positioning a single node, the safety of positioning hooks is greater than when positioning multiple nodes, the safety of medical glue and positioning hooks is comparable, and the appropriate positioning method should be chosen according to the individual situation of the patient.

Abstract
BACKGROUND The identification of small lung nodules is challenging during mini-invasive thoracic surgery. Unable to palpate them directly, surgeons have developed several methods to preoperatively localize pulmonary nodules, including the computed tomography-guided positioning of coils or metallic landmarks (hook wire) or bronchoscopic marking. METHODS We present a series of patients scheduled for the video-assisted thoracoscopic sublobar resection of small pulmonary nodules, in which we performed preoperative percutaneous computed tomography (CT)-guided nodule localization through the injection of a mixture of indocyanine green and human albumin. RESULTS A total of 40 patients underwent a preoperative CT-guided injection of indocyanine green followed by VATS resection within 24 h. Patients tolerated the procedure well, no pain medication was administrated, and no complications were observed during the marking procedure. All pulmonary nodules were easily detected and successfully resected. CONCLUSION the near-infrared dye marking solution of indocyanine green (ICG) with diluted human albumin was safe, effective, and easy to perform. The ICG solution has the potential to facilitate the accurate localization and resection of pulmonary nodules during VATS surgery, avoiding the risk of marker displacement/migration.

Abstract
In recent years, with the increases in microorganisms that express a multitude of antimicrobial resistance (AMR) mechanisms, the threat of antimicrobial resistance in the global population has reached critical levels. The introduction of the COVID-19 pandemic has further contributed to the influx of infections caused by multidrug-resistant organisms (MDROs), which has placed significant pressure on healthcare systems. For over a century, the potential for light-based approaches targeted at combatting both cancer and infectious diseases has been proposed. They offer effective killing of microbial pathogens, regardless of AMR status, and have not typically been associated with high propensities of resistance development. To that end, the goal of this review is to describe the different mechanisms that drive AMR, including intrinsic, phenotypic, and acquired resistance mechanisms. Additionally, the different light-based approaches, including antimicrobial photodynamic therapy (aPDT), antimicrobial blue light (aBL), and ultraviolet (UV) light, will be discussed as potential alternatives or adjunct therapies with conventional antimicrobials. Lastly, we will evaluate the feasibility and requirements associated with integration of light-based approaches into the clinical pipeline.

Abstract
BackgroundPreoperative localization is challenging due to the small diameter of pulmonary nodules or their deep location in the lung parenchyma during VATS surgery. The purpose of this study was to compare the efficacy and safety of both hook-wire and medical glue for pre-operative localization of pulmonary nodules.MethodsIn the current study, 158 patients were retrospectively analyzed (January 2019 and January 2020). The patients underwent hook-wire or medical glue for pre-operative localization of pulmonary nodules. Among them, 74 patients in the hook-wire group and 84 patients in the medical glue group underwent VATS anatomic segmentectomy or wedge resection after localization of pulmonary nodules. Pre-operative localization data from all patients were compiled. Moreover, the efficacy and safety of the two methods were evaluated according to localization success rates and localization-related complications.ResultsThe success rate of localization in the medical glue group was 100% while 97.3% in the hook-wire group. After localization of the pulmonary nodules, the incidence of minor pneumothorax in the medical glue group (11.9%) was lower than that in the hook-wire group (37.8%) (p=0.01). The incidence of mild pulmonary parenchymal hemorrhage in the medical glue group (13.1%) was also lower than that in the hook-wire group (24.3%) (p=0.000). The mean time from the completion of localization to the start of surgery was also longer in the medical glue group than in the hook-wire group (p=0.000). The mean visual analog scale (VAS) scores after localization were higher in the hook-wire group than in the medical glue group (p=0.02). In both groups, parenchymal hemorrhage was significantly associated with the needle length in hook-wire localization and the depth of the medical glue in the lung parenchyma (p = 0.009 and 0.001, respectively).ConclusionThese two localization methods are safe and effective in pre-operative pulmonary nodule localization. The medical glue localization method had a lower risk of complications, a higher localization success rate, less pain after localization and more flexibility in the arrangement of operation time.

Abstract
In the last few years, minimally invasive surgery has become the standard routine practice to manage lung nodules. Particularly in the case of robotic thoracic surgery, the identification of the lung nodules that do not surface on the visceral pleura could be challenging. Therefore, together with the evolution of surgical instruments to provide the best option in terms of invasiveness, lung nodule localization techniques should be improved to achieve the best outcomes in terms of safety and sensibility. In this review, we aim to overview all principal techniques used to detect the lung nodules that do not present the visceral pleura retraction. We investigate the accuracy of fluorescence guided thoracic surgery in nodule detection and the differences among the most common tracers used.

Abstract
Objective To investigate the utility of computed tomography (CT) scans to detect and
assess the margin status of pulmonary nodules that were insufflated after
being resected by video-assisted thoracic surgery. Materials and Methods This was a novel multicenter study conducted at two national referral centers
for thoracic diseases. Patients suspected of having lung cancer underwent
video-assisted thoracic surgery for the resection of pulmonary nodules,
which were submitted to postoperative CT. Measurements from the CT scans
were compared with the results of the histopathological analysis. Results A total of 37 pulmonary nodules from 37 patients were evaluated. The mean age
of the patients was 65 years (range, 36-84 years), and 27 (73%) were female.
A CT analysis of insufflated specimens identified all 37 nodules, and 33 of
those nodules were found to have tumor-free margins. The histopathological
analysis revealed lung cancer in 30 of the nodules, all with tumor-free
margins, and benign lesions in the seven remaining nodules. Conclusion Postoperative CT of insufflated suspicious lung lesions provides real-time
detection of pulmonary nodules and satisfactory assessment of tumor margins.
This initial study shows that CT of insufflated lung lesions can be a
valuable tool at centers where intraoperative histopathological analysis is
unavailable.

Abstract
OBJECTIVES Extended reality (XR), encompassing both virtual reality (VR) and augmented reality, allows the user to interact with a computer-generated environment based on reality. In essence, the immersive nature of VR and augmented reality technology has been warmly welcomed in all aspects of medicine, gradually becoming increasingly feasible to incorporate into everyday practice. In recent years, XR has become increasingly adopted in thoracic surgery, although the extent of its applications is unclear. Here, we aim to review the current applications of XR in thoracic surgery. METHODS A systematic database search was conducted of original articles that explored the use of VR and/or augmented reality in thoracic surgery in EMBASE, MEDLINE, Cochrane database and Google Scholar, from inception to December 2020. RESULTS Our search yielded 1494 citations, of which 21 studies published from 2007 to 2019 were included in this review. Three main areas were identified: (i) the application of XR in thoracic surgery training; (ii) preoperative planning of thoracic procedures; and (iii) intraoperative assistance. Overall, XR could produce progression along the learning curve, enabling trainees to reach acceptable standards before performing in the operating theatre. Preoperatively, through the generation of 3D-renderings of the thoracic cavity and lung anatomy, VR increases procedural accuracy and surgical confidence through familiarization of the patient's anatomy. XR-assisted surgery may have therapeutic use particularly for complex cases, where conventional methods would yield inadequate outcomes due to inferior accuracy. CONCLUSION XR represents a salient step towards improving thoracic surgical training, as well as enhancing preoperative planning and intraoperative guidance.

Abstract
BACKGROUND Small pulmonary nodules are increasingly detected at an earlier stage and need to be removed via video-assisted thoracoscopic surgery (VATS). However, small pulmonary nodules are often difficult to locate during VATS and are typically nonvisible and nonpalpable on the lung surface. A variety of localization techniques have been developed. Here, we explored the application of an intraoperative body surface localization (IOBSL) and/or anatomical landmark localization (ALL) in minimally invasive surgery for small pulmonary nodules. METHODS A total of 174 patients with small pulmonary nodules were divided into 3 groups: an IOBSL group, an ALL group, and an IOBSL+ALL group. VATS partial pneumonectomy was performed after the nodule localization, and the need for pulmonary segmentectomy/lobectomy and lymph node dissection was assessed according to the results of intraoperative rapid frozen section diagnosis. The duration, accuracy, and complications of each localization method were recorded and analyzed. RESULTS ALL had shorter distance to the nodules (P=0.0282) but longer localization duration (P<0.05) than did IOBSL. The IOBSL+ALL group had higher localization accuracy than did the other 2 groups (P=0.0003) but with longer localization duration (P<0.001). No intraoperative complications were noted. CONCLUSIONS The intraoperative technique has high localization accuracy and a low complication rate. It can be applied in VATS for pulmonary nodules, depending on the specific locations of the nodules.

Abstract
Increasing numbers of lung tumors are identified at early disease stages by diagnostic imaging in screening programs, but difficulties in locating these during surgical intervention has prevented an improved treatment outcome. Surgical biomarkers that are visible on diagnostic images, and that provide the surgeon with real-time image guidance during the intervention are thus highly warranted to bridge diagnostic precision into enhanced therapeutic outcome. In this paper, a liquid soft tissue marker for near infrared fluorescence and radio-guidance is presented. The biocompatible marker is based on the carbohydrate ester, sucrose acetate isobutyrate, ethanol, and a multifunctional naphthalocyanine dye, which enable near infrared fluorescence image-guided resection at short, medium and long tissue depths. Naphthalocyanine dyes have high quantum yields and may further act as chelators of radionuclides. Upon injection of the liquid marker, a gel-like depot is formed in situ at the site of injection, wherein the fluorescent dye and radionuclide is retained. The radiolabeled markers were optimized for minimal fluorescence quenching and high retention of the positron emission tomography radionuclide 64Cu. The performance of the radiolabeled marker was tested in vivo in mice, where it displayed high photostability over a period of 4 weeks, and high retention of 64Cu for 48 hours. The retention and biodistribution of 64Cu was quantified via PET/CT, and the fluorescence emission by an in vivo imaging system. The presented data demonstrate proof-of-concept for naphthalocyanine markers as multimodal imaging agents that can bridge the precision of diagnostic imaging into surgical interventions.

Abstract
Objectives Video assisted thoracoscopic surgery (VATS) can currently be used to diagnose and treat pulmonary nodules. However, intraoperative location of pulmonary nodules in VATS is challenging due to their small diameter and deep location in the pulmonary parenchyma. The purpose of this study was to report the clinical safety and effectiveness of CT-guided hook-wire for preoperative localization of malignant pulmonary nodules smaller than 1 cm in diameter. Methods From February 2017 to January 2018, we collected the data of 80 patients with malignant pulmonary nodules less than 1 cm in diameter who underwent CT-guided hook-wire preoperative localization and VATS surgery. The effectiveness of preoperative localization was evaluated based on surgical duration, success rate of VATS surgery, and localization-related complications. Results The diameter of pulmonary nodules were 0.85 ± 0.17 mm with a distance to the pleural surface of 19.66 ± 14.10 mm. The length of the hook-wire in the lung parenchyma was 29.17 ± 13.14 mm and hook-wire dislodgement occurred in 2 patients. Complications included 27 cases of minor pneumothorax and 18 cases of mild parenchymal hemorrhage. A significant correlation was observed between the length of the hook-wire in the lung parenchyma and mild parenchymal hemorrhage (P = 0.044). The average time of hook-wire localization was 9.0 ± 2.6 min and the average operation time for VATS was 89.02 ± 23.35 min without conversion thoracotomy. Conclusions CT-guided hook-wire localization of the lesion during VATS resection is safe for malignant pulmonary nodules with diameter less than 1 cm.

Abstract
2018年美国国立综合癌症网络关于非小细胞肺癌(non-small cell lung cancer, NSCLC)指南指出,对于早期NSCLC,解剖性肺叶切除为首选方案。随着电视胸腔镜技术的发展,以胸腔镜为代表的胸外科微创手术在临床得到了广泛应用。胸腔镜肺段切除术已经成为早期NSCLC的治疗方案之一。临床研究发现相较于肺叶切除,亚肺叶切除在早期NSCLC治疗中也可取得相似的结果并保留更多的肺功能,但肺段切除术后患者肺功能的改变尚存争议。本文将重点对胸腔镜肺段切除术后患者肺功能改变的研究进展做一综述。

Abstract
RATIONALE Computerized tomography (CT)-guided blue dye localization has been widely discussed for preoperative localization of pulmonary nodules. However, few studies have investigated this technique for intra-abdominal lesions. Although preoperative localization is not commonly required in laparotomy, it may assume importance with advancements in the field of laparoscopic surgery. PATIENT CONCERNS Herein, we report the cases of 2 patients diagnosed with colon cancer who underwent hemicolectomy with extended lymphadenectomy and subsequent chemotherapy. DIAGNOSES Follow-up CT scans showed newly developed metastatic lymphadenopathy and peritoneal tumor implants. INTERVENTIONS Considering the difficulty in identification of and access to the target lesions during laparoscopic surgery, preoperative CT-guided blue dye localization was performed in both cases. OUTCOMES All the target lesions were identified by the dye marker and removed successfully. The pathologic results revealed adenocarcinoma. LESSONS We established the following strategy for preoperative CT-guided dye localization of intra-abdominal lesions:Intra-abdominal lesions that are hard to identify due to their size or morphology, and difficult to approach due to their location or surrounding structures, maybe the candidates for this procedure, especially in cases of laparoscopic surgery.Operators should adjust their localization planning based on the surgery method, cutting path, and location of port sites. The target dye marker should be clearly visible in the presumed intra-operative field of view.A second dye marker should be made to ensure surgical success when the target dye marker is obscured by the surrounding structures in the presumed intra-operative field of view.

Abstract
Background Small, deep-seated lung nodules and sub-solid nodules are often difficult to locate without marking. Purpose To evaluate the success and complication rates associated with the use of indocyanine green (ICG) to localize pulmonary nodules before resection. Material and Methods This retrospective study was approved by our institutional review board. Informed consent for performing preoperative localization using ICG marking was obtained from all patients. Thirty-seven patients (14 men, 23 women; mean age = 63.1 years; age range = 10-82 years) with small peripheral pulmonary nodules underwent computed tomography (CT)-guided ICG marking immediately before surgery between March 2007 and June 2016. The procedural details and complication rates associated with ICG marking are described. Results The average nodule size and depth were 9.1 mm (range = 2-22 mm) and 9.9 mm (range = 0-33 mm), respectively. Marking was detected at the pleural surface in 35 patients (95%). Three cases of mild pneumothorax (8%), five cases of cough (14%), and one case of mild bloody sputum (3%) with no clinical significance were noted. There were no severe complications. The average duration required to perform the marking was 19.4 min (range = 12-41 min). Conclusion Our results indicate that CT-guided ICG marking is safe and useful for detecting the location of small pulmonary nodules preoperatively.

Abstract
Video-assisted thoracoscopic surgery (VATS) has gradually been implemented in thoracic surgery, and the VATS approach has now been extended to technically challenging procedures, such as segmentectomy. The definition of VATS segmentectomy is changing over time, and the repertoire of segmentectomy is getting wider with increasing reports on atypical segmentectomy. VATS segmentectomy bears surgical, oncological, and technical advantages; however, there are still areas of controversy, particularly regarding oncological outcomes. The indication of VATS segmentectomy is diverse and is used for treating lung cancer, metastatic lung tumors, or a variety of nonmalignant diseases. It is particularly valuable for the lung-sparing resection of deeply located small nodules or repeated surgery for multiple lung lesions. VATS segmentectomy requires a thorough analysis of segmental anatomy and a tailored preoperative planning with the assessment of surgical margins. Technical challenges include intraoperative navigation, methods to identify and dissect the intersegmental plane, and the prevention of air leakage. This review will discuss the present state of VATS segmentectomy, with a focus on past studies, current indications and techniques, and future view.

Abstract
BACKGROUND Unhooking or displacement of hookwire or microcoil due to technical failures is rather common. We aim to establish a new technique for remedial localization in the case of displacement or unhooking of primary mechanical localization during lung surgery. METHODS From February 2014 to September 2015, 18 consecutive cases of intraoperative dislodgement during video-assisted thoracoscopic surgery (VATS) were enrolled. Nodule's projection on body surface was located by analyzing computed tomography (CT) images, and a needle was inserted into thoracic cavity through this point. The lung was then inflated, and a small burn was made where the needle tip touched the visceral plural. Wedge resections were subsequently performed for these impalpable small lesions. RESULTS Eighteen solitary pulmonary nodules (SPNs) from 18 patients were scheduled for VATS wedge resections in this series, including 6 (33.3%) hookwire localization and 12 (66.7%) microcoil localization. Fifteen (83.3%) of 18 nodules were pure ground glass opacity (pGGO) and 3 (16.7%) mixed ground glass opacity (mGGO). The mean diameter of SPNs was 7.7±3.6 mm. The mean distance from SPN to pleura was 12.2±10.9 mm. During remedial localization, 17 (94.4%) nodules were removed successfully by wedge resection, and segmentectomy was performed only in one case with failed outcome. Paraffin pathology showed 2 (11.1%) atypical adenomatous hyperplasia (AAH), 11 (61.1%) adenocarcinoma in situ (AIS), 4 (22.2%) minimally invasive adenocarcinoma (MIA), and 1 (5.6%) inflammatory disease. CONCLUSIONS This remedial localization technique is practical and reliable. It is a good backup plan in the case of dislodgement, and it can help prevent extended lung resection.

Abstract
For the past decades, surgeries have become more complex, due to the increasing age of the patient population referred for thoracic surgery, more complex pathology and the emergence of minimally invasive thoracic surgery. Together with the early detection of thoracic disease as a result of innovations in diagnostic possibilities and the paradigm shift to personalized medicine, preoperative planning is becoming an indispensable and crucial aspect of surgery. Several new techniques facilitating this paradigm shift have emerged. Pre-operative marking and staining of lesions are already a widely accepted method of preoperative planning in thoracic surgery. However, three-dimensional (3D) image reconstructions, virtual simulation and rapid prototyping (RP) are still in development phase. These new techniques are expected to become an important part of the standard work-up of patients undergoing thoracic surgery in the future. This review aims at graphically presenting and summarizing these new diagnostic and therapeutic tools.

Abstract
PURPOSE Small pulmonary lesions that include ground-glass attenuation have been increasingly discovered because of progressive imaging diagnostic technologies. Despite the detection of such small lesions, sometimes it is quite difficult to localize them because of their size or considerable depth from the visceral pleura. In the present study, we examined the usefulness of computed tomography-guided lipiodol marking for thoracoscopic resection of impalpable pulmonary nodules. METHODS Fifty-six patients with an undiagnosed peripheral lesion(s) of the lung who had undergone preoperative computed tomography-guided lipiodol marking followed by video-assisted thoracoscopic surgery were studied. RESULTS All of the nodules were successfully marked by computed tomography-guided lipiodol marking, and all except for one case were localized by means of intraoperative fluoroscopy as clear spots. With regard to complications, pneumothorax occurred in 21 patients (37.5%), and only one patient required transient drainage. Although hemorrhaging in the lung parenchyma and hemosputum occurred in nine patients (16.1%) and one patient (1.8%), respectively, no patients were in serious condition. No intra- or postoperative mortality or morbidity was observed. CONCLUSION Preoperative computed tomography-guided lipiodol marking of small or impalpable pulmonary nodules is a safe and useful procedure for thoracoscopic resection of the lung.

Abstract
INTRODUCTION For lung squamous cell carcinomas, there are no pathological findings that have been universally accepted as prognostic factors, with the exception of pathological stage. Tumor budding and nuclear grade have been recognized as a poor prognostic factor in other carcinomas. In this study, we investigated whether pathological findings could determine prognosis in lung squamous cell carcinomas. METHODS All available tumor slides from patients with surgically resected, solitary lung squamous cell carcinomas (1999-2009) were reviewed (n = 485; stage I/II/III, 281/136/68). Tumors were evaluated for differentiation, subtypes (keratinizing, nonkeratinizing, basaloid pattern, papillary growth, and clear cell feature), tumor nest size (tumor budding and single cell invasion), and nuclear grade (nuclear diameter and mitosis). Overall survival (OS) was estimated using the Kaplan-Meier method (stratified by pathological stage), and group differences were investigated using the stratified log-rank test and the Cox proportional hazards model. RESULTS OS was significantly decreased in patients with versus without single cell invasion (p = 0.002 for the entire tumor and p = 0.001 for tumor edge), with large versus small nuclei (p = 0.011), and with high versus low grade tumor budding (p < 0.001 for maximum and p = 0.007 for total). In multivariate analyses, single cell invasion (hazard ratio [HR], 1.47-1.49), nuclear diameter (HR, 1.09-1.33), and tumor budding (HR, 1.04) were independent prognostic factors of OS. However, histologic subtyping including keratinizing, nonkeratinizing, basaloid, and clear cell subtypes did not show prognostic significance. CONCLUSIONS Pathological factors can help stratify prognosis in patients with lung squamous cell carcinomas.
