Abstract Background With the popularization of HRCT and VATS, the incidence of early stage lung cancer is increasing recent years. About 63% of small pulmonary nodules can not be accurately identified in VATS. We use 3-D reconstruction combined with dial positioning to analyze its accuracy and impact on patients undergoing VATS in our hospital. Method All patients underwent HRCT scanning and 3-D reconstruction preoperatively to determine the scope of surgery. The precise positional relationship between the nodule and the nearest rib must be recorded. Locate the plane of pulmonary nodule on CT, rotate the plane to make the affected side upwards, take the highest point of pleura as 12 o'clock on the dial, record the corresponding point of the nodule meticulously, mark the pulmonary nodule on the skin of the patient. A 18G indwelling needle was used to puncture through the marker into the visceral pleura. Electrocautery mark was made on the bleeding point of the lung surface. Then wedge resection or segmental resection was made. Materials and result From September 2019 to December 2020, 74 patients underwent VATS pulmonary nodule resection in our institute, with an average age of (56.4 ± 11.7) years old. A total of 83 nodules were resected in 74 patients, 23 nodules received segmentectomy and 60 nodules received wedge resection with 16 benign nodules and 67 malignant nodules. The distance between the nodules and pleura was (0–25) mm, with an average of (8.0 ± 3.9) mm. The target nodules were found in all patients, the positioning accuracy was 97.6%. All patients were satisfied with the positioning method, and there was no scar left at the skin puncture point after operation. Conclusion 3-D reconstruction combined with dial positioning method can reduce patients' anxiety preoperatively, avoid various complications, reduce hospitalization expenses, and has an acceptable accuracy and short learning curve, which can be further promoted and applied in clinic.

Context.— Optimal management of the patient with a solitary pulmonary nodule entails early diagnosis and appropriate treatment for patients with malignant tumors, and minimization of unnecessary interventions and procedures for those with ultimately benign nodules. With the growing number of high-resolution imaging modalities and studies available, incidentally found solitary pulmonary nodules are an increasingly common occurrence. Objective.— To provide guidance to clinicians involved in the management of patients with a solitary pulmonary nodule, including aspects of risk stratification, workup, diagnosis, and management. Data Sources.— Data for this review were gathered from an extensive literature review on the topic. Conclusions.— Logical evaluation and management pathways for a patient with a solitary pulmonary nodule will allow providers to diagnose and treat individuals with early stage lung cancer and minimize morbidity from invasive procedures for patients with benign lesions.

Abstract Background Pulmonary segmentectomy can be challenging when thoracic surgeons encounter anatomical anomalies. A displaced left apicoposterior bronchus is a rare bronchial anomaly that makes lung anatomical resection challenging. We herein present a case of successful left apicoposterior segmentectomy for lung cancer in a patient with an anomalous segmental bronchus. Case presentation A 70-year-old man was clinically diagnosed with early-stage lung cancer for which segmentectomy was indicated. A preoperative image revealed a displaced left apicoposterior bronchus that branched behind the left main pulmonary artery. With the aid of three-dimensional reconstruction imaging and systemic indocyanine green injection, we successfully performed left apicoposterior segmentectomy under complete video-assisted thoracic surgery. The pathological diagnosis was adenocarcinoma. The patient was alive without recurrence 8 months after segmentectomy. Conclusion Preoperative three-dimensional imaging and systemic indocyanine green injection enabled us to successfully conduct challenging segmentectomy in a patient with an anomalous bronchus.

Early Stage Lung Cancer

Not infrequently, a patient with newly diagnosed head and neck cancer is noted on preoperative chest radiography to have a solitary pulmonary nodule. It is initially unclear whether the pulmonary nodule is a benign lesion or a metastatic or primary lung malignancy. Considerable controversy exists regarding the evaluation of such patients as well as the treatment, assuming that the pulmonary lesion is malignant. We have reviewed the UCLA experience with patients who had head and neck cancers and pulmonary cancers no more than 5 years apart, and reviewed the literature on early stage lung cancer. We present a rational approach to the workup and treatment of patients with head and neck cancer and a pulmonary nodule on chest radiography.

Fact Sheet

IntroductionThe utilisation of chest CT for the evaluation of pulmonary disorders, including low-dose CT for lung cancer screening, is increasing in the USA. As a result, the discovery of both screening-detected and incidental pulmonary nodules has become more frequent. Despite an overall low risk of malignancy, pulmonary nodules are a common cause of emotional distress among adult patients.MethodsWe conducted a multi-institutional quality improvement (QI) initiative involving 101 participants to determine the effect of a pulmonary nodule fact sheet on patient knowledge and anxiety. Males and females aged 35 years or older, who had a history of either screening-detected or incidental solid pulmonary nodule(s) sized 3–8 mm, were included. Prior to an internal medicine or pulmonary medicine clinic visit, participants were given a packet containing a pre-fact sheet survey, a pulmonary nodule fact sheet and a post-fact sheet survey.ResultsOf 101 patients, 61 (60.4%) worried about their pulmonary nodule at least once per month with 18 (17.8%) worrying daily. The majority 67/101 (66.3%) selected chemotherapy, chemotherapy and radiation, or radiation as the best method to cure early-stage lung cancer. Despite ongoing radiographic surveillance, 16/101 (15.8%) stated they would not be interested in an intervention if lung cancer was diagnosed. Following review of the pulmonary nodule fact sheet, 84/101 (83.2%) reported improved anxiety and 96/101 (95.0%) reported an improved understanding of their health situation. Patient understanding significantly improved from 4.2/10.0 to 8.1/10.0 (p<0.01).ConclusionThe incorporation of a standardised fact sheet for subcentimeter solid pulmonary nodules improves patient understanding and alleviates anxiety. We plan to implement pulmonary nodule fact sheets into the care of our patients with low-risk subcentimeter pulmonary nodules.

Spatial Pyramid

Lung cancer mortality is currently the highest among all kinds of fatal cancers. With the help of computer-aided detection systems, a timely detection of malignant pulmonary nodule at early stage could improve the patient survival rate efficiently. However, the sizes of the pulmonary nodules are usually various, and it is more difficult to detect small diameter nodules. The traditional convolution neural network uses pooling layers to reduce the resolution progressively, but it hampers the network’s ability to capture the tiny but vital features of the pulmonary nodules. To tackle this problem, we propose a novel 3D spatial pyramid dilated convolution network to classify the malignancy of the pulmonary nodules. Instead of using the pooling layers, we use 3D dilated convolution to learn the detailed characteristic information of the pulmonary nodules. Furthermore, we show that the fusion of multiple receptive fields from different dilated convolutions could further improve the classification performance of the model. Extensive experimental results demonstrate that our model achieves a better result with an accuracy of 88 . 6 % , which outperforms other state-of-the- art methods.
