ABSTRACT

@#Objective     To explore the clinical efficacy and learning curve of robot-assisted thymectomy via subxiphoid approach. Methods    The clinical data of patients with robot-assisted thymectomy surgery via subxiphoid approach performed by the same surgical team in the Department of Thoracic Surgery of Shanghai Pulmonary Hospital from February 2021 to August 2022 were retrospectively analyzed. The cumulative sum (CUSUM) analysis and best fit curve were used to analyze the learning curve of this surgery. The general information and perioperative indicators of patients at different learning stages were compared to explore the impact of different learning stages on clinical efficacy of patients. Results    A total of 67 patients were enrolled, including 31 males and 36 females, aged 57.10 (54.60, 59.60) years. The operation time was 117.00 (87.00, 150.00) min. The best fitting equation of CUSUM learning curve was y=0.021 2x3–3.192 5x2 +120.17x–84.444 (x was the number of surgical cases), which had a high R2 value of 0.977 8, and the fitting curve reached the top at the 25th case. Based on this, the learning curve was divided into a learning period and a proficiency period. The operation time and intraoperative blood loss in the proficiency stage were significantly shorter or less than those in the learning stage (P<0.001), and there was no statistical difference in thoracic drainage time and volume between the two stages (P>0.05). Conclusion    The learning process of robot-assisted thymectomy via subxiphoid approach is safe, and this technique can be skillfully mastered after 25 cases.

ABSTRACT

Treatment of stage Ⅲ NSCLC is challenging, and the best treatment strategy is still controversial. The emergence of new therapeutic agents and philosophy also continues to redefine the range of resectable/ potentially resectable NSCLC. Resectable N2-stage Ⅲ lymph nodes are usually scattered with well-defined margins and no adhesions to surrounding structures. Neoadjuvant therapy followed by surgery has lower local recurrence rate compared to radical radiotherapy. According to current guidelines, surgical treatment is not recommended for N3-stage Ⅲ NSCLC. However, for regional N3 disease with continuous response to chemotherapy, after careful selection, surgery may worth a try. The efficacy of immunotherapy in locally advanced lung cancer has been confirmed in many prospective clinical trials. Neoadjuvant immunotherapy significantly improves major pathological remission rates and pathological complete remission rates, which allows these downstaging patients have the chance to receive surgery and thus improve their long-term prognosis. For efficacy assessment of neoadjuvant immunotherapy, pathological biopsy is more reliable than CT. In conclusion, the progress in multimodality neoadjuvant therapy will provide more surgical opportunities and better long-term prognosis for patients with potentially resectable stage Ⅲ NSCLC.

ABSTRACT

Malignant pleural mesothelioma(MPM) is a kind of rare and aggressive malignant neoplasm. Surgery plays one of the most important roles in the treatment of MPM. However, due to the high morbidity and mortality reported, the survival benefit and indication of surgery are still controversial. This article will review the surgical indications, discuss and compare the roles of extrapleural pneumonectomy(EPP) and pleurectomy / decortication(P/D) which aim to achieve macroscopic complete resection(MCR) in the treatment of MPM. Finally, we summarized the progress of other treatment methods including targeted therapy and immunotherapy.

ABSTRACT

Objective:To summarize our experience in diagnosis and treatment of patients with pulmonary mucosa-associated lymphoid tissue-derived(MALT) lymphoma and to explore the role of surgery.Methods:We retrospectively analyzed the clinical and follow-up data of 86 patients with pulmonary MALT lymphoma in Shanghai Pulmonary Hospital from January 2000 to December 2018. 86 cases were identified with 44 males and 42 females. The mean age was(56.7±10.6) years old. 38(44.2%) cases had symptoms mainly presenting as cough and sputum at diagnosis. The chest CT scan of the patients showed pulmonary consolidation in 39 cases, nodule/mass shadow in 37 cases, usually with air bronchogram. Only 8(9.3%) cases could be diagnosed by non-surgical approach. 58 cases received complete resection, 10 of which followed chemotherapy. 8 of 17 cases who received incomplete resection accepted chemotherapy. The rest 11 cases who experienced surgical biopsy because of uncertain diagnosis were treated by chemotherapy or radio-chemotherapy or just watch-to-wait.Results:The median follow-up of 83 cases was 64 months, ranged from 24 to 219 months. The estimated 5-year and 10-year OS rates were 95.0% and 76.8%, while 5-year and 10-year PFS were 75.7% and 35.1% respectively. Patients who received complete resectionhad better PFS( P<0.001)but similar OS( P=0.395), compared with those received incomplete resection. There were no significant difference in OS and PFS between patients who received complete resection accepted chemotherapy or not( P>0.05). Conclusion:Pulmonary MALT lymphoma has an indolent nature with an excellent long-term survival. Diagnosis is difficult to be made by non-surgical approach. Surgery plays an important role of treatment of pulmonary MALT lymphoma, due to significant improvement of diagnosis rate and radical treatment of localized disease by complete resection.

ABSTRACT

Objective:To explore the sex-based heterogeneity in demographic and pathological trends of lung cancer during the past 30 years.Methods:Patients with primary lung cancer who received surgical treatment in the Department of thoracic surgery, Shanghai Pulmonary Hospital Tongji University from 1989 to 2018 were retrospectively analyzed. The differences between male and female patients in age, smoking history, pathological stage and type were compared. Mann- Kendall trend test was performed for trend analysis. Results:A total of 58 433 patients were included in this study, encompassing 30 729(52.6%) men and 27 , 704(47.4%) women. Compared with male patients, female patients were younger(56.0 years old vs. 59.7 years old), and had a higher proportion of non-smokers(98.3% vs. 52.3%), stage Ⅰ lung cancers(60.6% vs. 49.3%), and adenocarcinoma(93.7% vs. 56.1%, all P-values <0.001). Trend analyses revealed that the proportion of female patients increased year by year, and surpassed males in 2015, with the current ratio of male to female being 1∶1.5. After 2013, the age of onset in females was getting younger, and the average age decreased from 58.7 years old to 54.7 years old( P=0.02). The decrease in the proportion of smoking patients was mainly reflected by male patients(from 68.5% to 31.1%, P<0.01). Stage Ⅰ lung cancers in male and females outnumbered advanced stage in 2012 and 2010, respectively, with a much higher proportion in female patients. Among male patients, adenocarcinoma has replaced squamous cell carcinoma as the most common pathological type since 2012, while in female patients adenocarcinoma remained the most common pathological type of lung cancer, and its proportion continued to increase reaching over 98%. Conclusion:A dramatic change in gender distribution was noticed during the past 30 years. Female patients became the primary population in surgically-treated lung cancers, with a trend of getting younger. The proportion of smokers and squamous cell carcinoma decreased significantly in male patients, and adenocarcinoma has become the most common pathological type of lung cancer. The proportion of stage Ⅰ lung cancers was on a dramatic rise, with the popularization of CT screening for lung cancer.

ABSTRACT

Objective:To evaluate the effect of prolonged graft cold ischemia time(CIT)on outcomes of lung transplantation(LTx).Methods:Clinical data are retrospectively reviewed for 111 patients undergoing LTx at Affiliated Shanghai Pulmonary Hospital of Tongji University between January 2019 and January 2022. They are divided into two groups of prolonged CIT(8~12 h, 41 cases)and control(<8 h, 70 cases)according to CIT. Kaplan-Meier method is employed for estimating 1-year cumulative survival rate and multivariable Cox proportional hazard regression model for identifying independent risk factors of 1-year mortality.Results:No significant inter-group difference existed in the incidence of primary graft dysfunction grade Ⅲ within the first 72 h post-LTx(21.2% vs. 16.3%). The 30-day(90.2% vs. 94.3%)and 90-day(82.9% vs. 82.9%)survival rates are comparable between two groups. Similarly 1-year cumulative survival is also comparable between two groups (74.6% vs. 60.4%, Log-rank P=0.279). Multivariate Cox regression analysis indicated that prolonged CIT was not associated with an elevated risk of 1-year mortality( HR 0.691; 95% CI: 0.317~1.506). However, an absence of ECMO support during surgery( HR 3.562; 95% CI: 1.061~11.959)and postoperative mechanical ventilation for >3 days(HR 2.892; 95% CI: 1.387~6.031)elevate 1-year risk of mortality. Conclusions:Prolongation of CIT to 8~12 h has no adverse effect on the prognosis of recipients. Given a great scarcity of donor lungs and a growing number of LTx candidates, it is reasonable to accept prolonged CIT donor lungs for clinical LTx.

ABSTRACT

Objective:To explore the airway pathogen characteristics and examine the correlation between donor-derived pathogens and post-transplant outcomes in patients after lung transplantation (LT).Methods:Between January 1, 2015 and December 31, 2019, retrospective review was conducted for clinical and microbiological data of 88 LT recipients.Airway pathogen percentage of different microorganisms and evolution of drug-resistance were examined.Drug-resistant pathogen positive group (n=71) and negative group (n=17) were assigned according to whether or not drug-resistant pathogens were detected.Survival analysis was conducted by Log-rank with 3-year follow-ups.Between April 11, 2020 and September 5, 2020, prospective study was conducted in 14LT recipients.The potential pathogenic bacteria from donor lungs were detected by metagenomic next generation sequencing and the impact of those bacteria was examined on 1-year post-transplantation outcome in 2020.Microbial diversity and richness were shown with Shannon index.The outcome variables included heart rate, neutrophil count, lymphocyte count, immunoglobulin level and pulmonary spirometry.ANOVA and Pearson's correlation analysis were performed for elucidating the relationship between airway microbiota and post-LT outcomes.Results:From 2015 to 2019, 88 recipients were recruited and 992 strains of airway pathogens were isolated, including bacteria 796 strains and fungi 196 strains.Gram-negative bacteria (704 strains) accounted for 88.4% of all bacteria.The detection rates of Gram-positive bacteria, Klebsiella pneumonia (Kp), Acinetobacter baumannii (Ab), Stenotrophomonas maltophilia and Candida increased in 2019 than that in 2015 (8.2% vs. 5.3%, 13.6% vs. 13.2%, 33.2% vs. 17.5%, 6.5% vs. 5.3%, 26.6% vs. 20.2%). Drug resistance rate of Kp to imipenem was 68.18% in 2019 and drug resistance rate of Ab to imipenem 98.44%.The 3-year survival rate was 46.3% and 35.3% in drug-resistance positive and negative groups and the difference was insignificant ( P=0.410). Fourteen recipients were enrolled in 2020.Potential pathogenic bacteria could be detected in all donor samples.Five recipients carried the same bacteria and two died during 1-year follow-up.Nine recipients did not carry the donor-derived pathogens and two died during 1-year follow-up.The diversity of donor/recipient-derived airway microbiota (Shannon index) showed no correlation with the outcomes of 1-year follow-up by Pearson's correlation test. Conclusions:Gram-negative bacteria predominated in airway pathogens of recipients post-LT.The drug resistance rate to imipenem remained high.The donor/recipient-derived pathogen isolates showed no correlation with immediate outcomes post-LT.

ABSTRACT

@#Objective    To compare the clinical effects of segmentectomy and lobectomy for ≤2 cm lung adenocarcinoma with micropapillary and solid subtype negative by intraoperative frozen sections. Methods    The patients with adenocarcinoma who received segmentectomy or lobectomy in multicenter from June 2020 to March 2021 were included. They were divided into two groups according to a random number table, including a segmentectomy group (n=119, 44 males and 75 females with an average age of 56.6±8.9 years) and a lobectomy group (n=115, 43 males and 72 females with an average of 56.2±9.5 years). The clinical data of the patients were analyzed. Results    There was no significant difference in the baseline data between the two groups (P>0.05). No perioperative death was found. There was no statistical difference in the operation time (111.2±30.0 min vs. 107.3±34.3 min), blood loss (54.2±83.5 mL vs. 40.0±16.4 mL), drainage duration (2.8±0.6 d vs. 2.6±0.6 d), hospital stay time (3.9±2.3 d vs. 3.7±1.1 d) or pathology staging (P>0.05) between the two groups. The postoperative pulmonary function analysis revealed that the mean decreased values of forced vital capacity and forced expiratory volume in one second percent predicted in the segmentectomy group were significantly better than those in the lobectomy group (0.2±0.3 L vs. 0.4±0.3 L, P=0.005; 0.3%±8.1% vs. 2.9%±7.4%, P=0.041). Conclusion    Segmentectomy is effective in protecting lungs function, which is expected to improve life quality of patients.

ABSTRACT

After decades of development, thymus minimally invasive surgery has derived a variety of surgical methods. In selected cases, it can achieve equivalent therapeutic effect as open surgery. Because mediastinal disease is rare compared with other chest diseases, there is a lack of large-scale comparative study among different surgical methods, and the choice of surgical approaches is mostly based on the experience and habit of the operator. The purpose of this review is to discuss the evolution of minimally invasive thymus surgery, summarize several kinds of minimally invasive thymus surgery approaches that are widely used in and abroad, and analyze the integration and improvement strategies of minimally invasive thymus surgery in China.

ABSTRACT

Objective:To evaluate the inpatient PE incidence and thromboprophylaxis after thoracic surgery according to adjusted Caprini VTE risk assessment model.Methods:The study selected consecutively 500 patients who received thoracic surgery from first of June in consecutive three years of 2015, 2016 and 2017. We retrospectively assessed these 1 500 patients using Caprini VTE risk model and recorded baseline characteristics, postoperative prophylaxis, and PE incidence.Results:Only 19.4% of 2015-year patients received pharmacologic prophylaxis, while the rate reached up to 65.2% in 2016 and 77.2% in 2017. PE occurred on 4 cases in 2015, 1 case in 2016, and 0 case in 2017. The overall incidence of PE was 0.3%(5/1 500). The PE incidence negatively correlated with the implementation of prophylaxis( r=-0.04, P=0.07). The PE risk(odds ratio) increased 4.68 times(95% CI: 0.525-41.800) when patients did not receive prophylaxis in PE cohort. Postoperative pharmacologic prophylaxis with current dosing did not affect the drainage of chest tube after surgery. Conclusion:Implementation of an adjusted Caprini risk assessment protocol can be useful for the thoracic postoperative patients to receive appropriate thromboprophylaxis. Current pharmacologic prophylaxis protocol should be safe and enough to prevent PE after thoracic surgery.

ABSTRACT

Multiple primary lung cancer(MPLC) is defined as the simultaneous or successive occurrence of two or more primary lung cancers in the same individual, and distinguishing MPLC from intrapulmonary metastasis can be challenging. There is ambiguity in the treatment of such tumors, which can be influenced by the number, distribution of MPLC as well as patient cardiopulmonary function. This review will summarize current understanding of diagnostic criteria, stage classification, and treatment strategy for multiple primary lung cancer.

ABSTRACT

Objective:The Corona Virus Disease 2019 (COVID-19), caused by a novel virus (2019-nCoV), is a current epidemic throughout the world. Widespread discussion has been going on about the suitability of lung transplantation for critically-ill patients as an emergent treatment. So far lung transplantation has been performed sporadically in China; however, the relevant treatment and prognosis after transplantation are inconclusive. This article mainly reviews the literature in terms of transplantation and viral infection, indications of lung transplantation, postoperative complications, ethics, and health economics, to elaborate this argument and to further explore the future of lung transplantation for COVID-19.
