Correlation between pre-anesthesia anxiety and emergence agitation in non-small cell lung cancer surgery patients

BACKGROUND Preoperative anxiety is a common emotional problem during the perioperative period and may adversely affect postoperative recovery.Emergence agitation(EA)is a common complication of general anesthesia that may increase patient discomfort and hospital stay and may be associated with the development of postoperative complications.Pre-anesthetic anxiety may be associated with the development of EA,but studies in this area are lacking.AIM To determine the relationship between pre-anesthetic anxiety and EA after radical surgery in patients with non-small cell lung cancer(NSCLC).METHODS Eighty patients with NSCLC undergoing surgical treatment between June 2020 and June 2023 were conveniently sampled.We used the Hospital Anxiety and Depression Scale’s(HADS)anxiety subscale(HADS-A)to determine patients’anxiety at four time points(T1-T4):Patients’preoperative visit,waiting period in the surgical waiting room,after entering the operating room,and before anesthesia induction,respectively.The Riker Sedation-Agitation Scale(RSAS)examined EA after surgery.Scatter plots of HADS-A and RSAS scores assessed the correlation between patients’pre-anesthesia anxiety status and EA.We performed a partial correlation analysis of HADS-A scores with RSAS scores.RESULTS NSCLC patients’HADS-A scores gradually increased at the four time points:7.33±2.03 at T1,7.99±2.22 at T2,8.05±2.81 at T3,and 8.36±4.17 at T4.The patients’postoperative RSAS score was 4.49±1.18,and 27 patients scored≥5,indicating that 33.75%patients had EA.HADS-A scores at T3 and T4 were significantly higher in patients with EA(9.67±3.02 vs 7.23±2.31,12.56±4.10 vs 6.23±2.05,P<0.001).Scatter plots showed the highest correlation between HADS-A and RSAS scores at T3 and T4.Partial correlation analysis showed a strong positive correlation between HADS-A and RSAS scores at T3 and T4(r=0.296,0.314,P<0.01).CONCLUSION Agitation during anesthesia recovery in patients undergoing radical resection for NSCLC correlated with anxiety at the time of entering the operating room and before anesthesia induction.

Expert Consensus on the Diagnosis and Treatment of Anticancer Drug-Induced Interstitial Lung Disease

Drug-induced interstitial lung disease(DILD)is the most common pulmonary adverse event of anticancer drugs.In recent years,the incidence of anticancer DILD has gradually increased with the rapid development of novel anticancer agents.Due to the diverse clinical manifestations and the lack of specific diagnostic criteria,DILD is difficult to diagnose and may even become fatal if not treated properly.Herein,a multidisciplinary group of experts from oncology,respiratory,imaging,pharmacology,pathology,and radiology departments in China has reached the“expert consensus on the diagnosis and treatment of anticancer DILD”after several rounds of a comprehensive investigation.This consensus aims to improve the awareness of clinicians and provide recommendations for the early screening,diagnosis,and treatment of anticancer DILD.This consensus also emphasizes the importance of multidisciplinary collaboration while managing DILD.

The results and prognosis of different treatment modalities for solitary metastatic lung tumor from nasopharyngeal carcinoma:a retrospective study of 105 cases

Background and Objective:Nasopharyngeal carcinoma (NPC) is known for its propensity for distant metastases.Lung metastasis is one of the most important causes of death for patients with NPC.Solitary metastatic lung tumor from NPC is a distinctive group associated with a better survival.This study was to find a more effective treatment modality and prognostic factors for the group.Methods:Clinical data of 105 cases of solitary metastatic lung tumor from NPC were retrospectively analyzed.Survival rate was calculated by the Kaplan-Meier method.The difference of survival between the patients treated by different modalities was evaluated by the log-rank test.The Cox univariate and multivariate analyses of gender, age, pathologic type, stage, adjuvant chemotherapy, evaluation of treatment for NPC, disease-free interval, size of metastatic tumor, pulmonary hilar and/or mediastinal lymph node metastasis, treatment modalities, recurrent distant metastases and/or relapse of NPC were conducted.Results:The local control rate was 53.8% in chemotherapy group, 88.0% in radiotherapy +/-chemotherapy group, and 96.4% in operation +/-chemotherapy group (P<0.01).The most promising progression-free survival (PFS) and overall survival (OS) were obtained with operation +/-chemotherapy and followed by radiotherapy +/-chemotherapy.Both of them showed much better efficacy than chemotherapy (P<0.001).The Cox multivariate analysis showed that recurrent distant metastases and/or relapse of NPC affected the survival (OR=2.087, 95% CI=1.277-3.410, P=0.003).The T stage of NPC, size of metastatic tumor, hilar and/or mediastinal lymph node metastasis, and the treatment modality were independent prognostic factors.Conclusions:Operation +/-chemotherapy and radiotherapy +/-chemotherapy are better treatment of solitary metastatic lung tumor from NPC, which could improve the local control and prolong the PFS and OS.Chemotherapy is recommended for patients with higher T stage of NPC, size of metastatic tumor ≥3 cm, pulmonary hilar and/or mediastinal lymph node metastasis.

Anlotinib in combination with Envolizumab plus Etoposide for the treatment of EX-SCLC:a case report

Background:Small cell lung cancer(SCLC)is an aggressive malignant tumor with strong immunosuppressive effects,characterized by rapid doubling time and poor prognosis.Currently,effective therapeutic options are urgently needed for Extensive-stage small-cell lung Cancer.Case description:In the present case,a combination therapy of anlotinib,envolizumab,and etoposide was administered to treat an 80-year-old female patient with extensive-stage SCLC accompanied by mediastinal lymph node and bone metastasis.After two cycles of treatment,the tumor lesions in the right lungs decreased from 5.04*3.44 cm to 1.65*1.42 cm.As of now,no significant mass is seen there and no serious adverse reactions in this patient.Until September 2023,she has survived for 18 months with no disease progression.Conclusions:Research shows that Alectinib,in combination with evolocumab plus etoposide,could be an original,viable therapeutic option for the treatment option of patients with extensive-stage SCLC.

Identification of lncRNAs associated with T cells as potentialbiomarkers and therapeutic targets in lung adenocarcinoma

Lung adenocarcinoma (LUAD) is the most common and deadliest subtype of lung cancer. To select moretargeted and effective treatments for individuals, further advances in classifying LUAD are urgently needed. Thenumber, type, and function of T cells in the tumor microenvironment (TME) determine the progression andtreatment response of LUAD. Long noncoding RNAs (lncRNAs), may regulate T cell differentiation, development,and activation. Thus, our aim was to identify T cell-related lncRNAs (T cell-Lncs) in LUAD and to investigatewhether T cell-Lncs could serve as potential stratifiers and therapeutic targets. Seven T cell-Lncs were identified tofurther establish the T cell-related lncRNA risk score (TRS) in LUAD. Low TRS individuals were characterized byrobust immune status, fewer genomic alterations, and remarkably longer survival than high TRS individuals. Theexcellent accuracy of TRS in predicting overall survival (OS) was validated in the TCGA-LUAD training cohort andthe GEO-LUAD validation cohort. Our data demonstrated the favorable predictive power of the TRS-basednomogram, which had important clinical significance in estimating the survival probability for individuals. Inaddition, individuals with low TRS could respond better to chemotherapy and immunotherapy than those with highTRS. LINC00525 was identified as a valuable study target, and the ability of LUAD to proliferate or invade wassignificantly attenuated by downregulation of LINC00525. In conclusion, the TRS established by T cell-Lncs couldunambiguously classify LUAD patients, predict their prognosis and guide their management. Moreover, our identifiedT cell-Lncs could provide potential therapeutic targets for LUAD.

Cone beam computed tomography-guided differences among registration methods for lung cancer and the effects of tumor position,treatment model,and tumor size on positioning errors

Objective To explore the differences in three different registration methods of cone beam computed tomography(CBCT)-guided down-regulated intense radiation therapy for lung cancer as well as the effects of tumor location,treatment mode,and tumor size on registration.Methods This retrospective analysis included 80 lung cancer patients undergoing radiotherapy in our hospital from November 2017 to October 2019 and compared automatic bone registration,automatic grayscale(t+r)registration,and automatic grayscale(t)positioning error on the X-,Y-,and Z-axes under three types of registration methods.The patients were also grouped according to tumor position,treatment mode,and tumor size to compare positioning errors.Results On the X-,Y-,and Z-axes,automatic grayscale(t+r)and automatic grayscale(t)registration showed a better trend.Analysis of the different treatment modes showed differences in the three registration methods;however,these were not statistically significant.Analysis according to tumor sizes showed significant differences between the three registration methods(P<0.05).Analysis according to tumor positions showed differences in the X-and Y-axes that were not significant(P>0.05),while the autopsy registration in the Z-axis showed the largest difference in the mediastinal and hilar lymph nodes(P<0.05).Conclusion The treatment mode was not the main factor affecting registration error in lung cancer.Three registration methods are available for tumors in the upper and lower lungs measuring<3 cm;among these,automatic gray registration is recommended,while any gray registration method is recommended for tumors located in the mediastinal hilar site measuring<3 cm and in the upper and lower lungs≥3 cm.

Discussion on the treatment of Alzheimer's disease from the spleen based on intestinal flora

Alzheimer's disease(AD)is a clinically common degenerative disease of the central nervous system with a complex pathogenesis,which seriously endangers the physical and mental health of the elderly.In recent years,a large number of studies have shown that the intestinal flora can regulate the central nervous system through the brain-gut axis,thereby participating in the occurrence and development of AD.AD belongs to the category of"dementia"and"forgetfulness"in traditional Chinese medicine.It is caused by internal injury of seven emotions,old age and chronic illness,which can cause insufficient blood,deficiency of kidney essence,and blockage of phlegm and blood.To use,treat more from the heart,liver and kidney.We believe that phlegm turbidity blocking the orifice is the key to the pathogenesis of AD.It should be treated from the spleen,and according to the characteristics of the pathogenesis,the method of warming the spleen and dredging the collaterals and resuscitation is proposed to prevent AD.This article takes the intestinal flora as the starting point to discuss the research progress of treating AD from the spleen.

Liver fire invading the lung: Theoretical basis, identification and treatment

Liver fire invading the lung (also called wood-fire torturing metal) is widely seen in various respiratory diseases.In order to understand this pattern well,from the perspective of the five elements theory and zang-fu theory in Chinese Medicine,we systematically reviewed and discussed the physiological and functional characteristics of the liver and lung,the liver -lung relationship,the pathogenesis and identification of the pattern,as well as the commonly used basic formulas for the treatment of this pattern,including White-Draining Powder (Xiè Bái Sǎn,泻白散),Liver Heat-Dissolving Decoction (Huà Gān Jiān,化肝煎),Indigo and Clam Shell Powder (Dài Ge Sǎn,黛蛤散)and Hemoptysis-Relieving Formula(KéXuè Fāng,咳血方).Two examples of clinical modifications of these formulas in the treatment of hemoptysis and asthma are provided in this article.It should be noted that in the treatment of pulmonary diseases,these formulas should be used flexibly,and modified in accordance to the condition of the patient.

Comparison of the dose to lung volume between supine and prone position during treatment planning

Objective The aim of the study was to compare the dose to lung volume in the supine and prone position while designing Cyber Knife treatment plans to treat metastatic tumors in the spinous processes of the thoracic vertebrae, and offer a reference for reducing damage to normal tissues. Methods Nine cases of metastatic tumors in the spinous processes of the thoracic vertebrae were selected, and then we designed treatment plans based on the supine and prone positions and compared the results. Results In contrast with the treatment plan based on the prone position, the one for the supine position required 14862–36337 MU more; the lung D5% was 5.20–7.90 Gy higher; and the lung D20% was 2.61–5.73 Gy higher. The difference of dose to spine volume between the two plans was –2.21–2.67 Gy; to the skin volume was –3.93–7.85 Gy; and to the esophagus was 0.28–6.39 Gy. Conclusion The treatment plan based on the prone position of patients can better protect lung tissues than the one based on the supine position, and can also improve the availability of beams.

Expert Consensus on Prevention and Treatment of COVID-19 Infection in Patients with Lung Cancer

Corona virus disease 2019(COVID-19)infection has become a major public health issue affecting human health.The main goal of epidemic prevention and control at the current stage in China is to“protect people’s health and prevent severe cases”.Patients with lung cancer who receive antitumor therapy have low immunity,and the risk of severe illness and death once infected is much higher than healthy people,so they are vulnerable to COVID-19 infection.At present,less attention has been paid to the prevention and treatment of COVID-19 infection in patients with lung cancer in domestic guidelines and consensus.Based on the published data in China and abroad,we proposed recommendations and formed expert consensus on the vaccination of COVID-19,the use of neutralizing antibodies and small molecule antiviral drugs for patients with lung cancer,for physician’s reference.

Mucoepidermoid carcinoma of the lung with hemoptysis as initial symptom: A case report

BACKGROUND Mucoepidermoid carcinoma of the lung is a rare malignant tumor,accounting for 0.1%–0.2%of all lung malignancies.It is a primary salivary gland tumor of the lung.Surgical resection is the primary treatment for pulmonary mucoepidermoid carcinoma,for which there has been no standardized treatment strategy.This article reports a case of a young woman with pulmonary mucoepidermoid carcinoma with hemoptysis as the first symptom.CASE SUMMARY A 24-year-old female patient presented with"4 d of hemoptysis"as the chief complaint.She had no special history and denied any smoking or drinking history.Physical examination revealed that the vital signs were stable and scattered small wet rales were heard in the left lung.After admission,the lung tumor markers were checked,and no abnormalities were found.After completing the bronchoscopy,a spherical lesion was observed at the main bronchus 1.5 cm away from the protubercle,with obvious pulsation and little blood seepage on the surface,and histopathological biopsy results showed acute and chronic inflammation.She was transferred to the Department of Thoracic Surgery for surgical treatment on the 16th day after admission.After exclusion of surgical conjunctures,the patient underwent resection of the tumor in the left main bronchus with single-pore video-assisted thoracic surgery on the 19th day after admission.The postoperative histopathological biopsy results showed mucoepidermoid carcinoma of the lung.The patient and her family refused to complete genetic testing and she was discharged from the hospital on the 8th day after surgery.During the follow-up period,the patient experienced shortness of breath after feeling active and had no special discomfort.CONCLUSION We have documented a case of moderately differentiated mucoepidermoid lung cancer with hemoptysis as the first symptom to improve clinicians'understanding of the disease and provide a new dimension of thinking for its future diagnosis and treatment.

Review of the treatment of metastatic non small cell lung carcinoma:A practical approach

In recent years,as we have a better knowledge and understanding of the biology of non small cell lung carcinoma(NSCLC),which leads us to targeting biomarkers driving the NSCLC carcinogenesis and metastatic potential,we now have an increased number of options to offer our patients with NSCLC.We also realize the importance of distinguishing squamous and non squamous histology to guide our treatment decisions of NSCLC.The palliative care concomitant with therapies from the very start of the treatment also showed an impact on survival.This review examines the treatment options in all lines of therapy for metastatic NSCLC that have been approved in Canada,the United States,or Europe.

Multisegmental Lobe Bronchoplasty for the Treatment of Non-small-cell Lung Cancer

Bronchoplasty was extended to the segmental level and the effect of the multi-segmental surgery for the central non-small lung cancer was observed. The involved lobular bronchi and part of main bronchi were resected and single-layer continuous suture with 5-0 Prolene was used for suturing of the carina of the reconstructed segmental bronchi to form lobular bronchi. Then, single-layer continuous suture with 4-0 Prolene was employed to anastomose the ＂lobular bronchi＂ with main bronchi Our results showed that the 15 bronchoplasties were successfully performed. The tumors were completely removed and postoperatively, the pulmonary functions of the patients were substantially improved. No broncho-pleural fistula and stomal stenosis took place in all the cases. The quality of life of the patients were obviously improved. It is concluded that multisegmental bronchoplasty can completely remove the tumor of central non-small-cell lung cancer and conserve more non-involved lung. The procedure is especially suitable for those patients with severely impaired lung functions and it expands the indications of surgical resection of lung cancer.

Application of Pulmonary Venoplasty in the Surgical Treatment of Lung Cancer

Presented in this study were three cases of lung cancer undergoing pulmonary venoplasty. In the 3 patients with central type of carcinoma of lung involving pulmonary vein, the main branch of right superior pulmonary vein and the distal end of the superior-lobe vein were occluded. The root part of the vein of right-middle lobe, plus part of vessel of of right superior vein was resected. The right superior vein was reconstructed by continuous 6-0 Prolene sutures. After the operation, the reconstructed was patent and the surgical margin was tumor-free. Postoperatively, clinical manifestations and plain chest films did not show any signs of venous blockade. The patients were discharged healed 3 weeks after the operation. The technical details of the surgery were presented, the improvements on the basis of traditional methods were discussed and its clinical application was evaluated. It is concluded that pulmonary venoplasty is a safe and feasible operation. Further improvement of the surgery will help conserve more lung tissue and benefit more patients because of expanded indications.

Safety and Efficacy of Racotumomab-Alum Vaccine as Second-Line Therapy for Advanced Non-Small Cell Lung Cancer

Despite extensive clinical research in non-small cell lung cancer (NSCLC), overall survival is still poor. Racotumomab-alum is an anti-idiotypic cancer vaccine that targets NeuGcGM3 tumor associated ganglioside. The aim of this study was to evaluate safety and efficacy of racotumomab-alum in advanced NSCLC patients with progressive disease. This expanded access program included 86 histologically confirmed NSCLC patients, 18 years or older age, with advanced disease and without therapeutic option, with ECOG performance status ≤3, adequate organ functions and signed informed consent. The primary endpoint was overall survival and toxicity was measure assessed treatment-related toxicity according CTCAEv3. The study was approved by ethical review boards of participant institutions. Racotumomab-alum treatment consisted in 5 biweekly intradermal doses (1 mg/mL) during the induction phase of treatment (2 months). The maintenance phase consisted in monthly re-immunizations until unacceptable toxicity or PS worsening. The median overall survival time of all patients treated with racotumomab-alum was 8.96 months. The survival rates at 12 and 24 months were 42.8% and 28.0%, respectively. Patients that completed the induction phase of treatment (five doses or more) reached a median OS of 12.1 months. The most common adverse events were injection site reaction, bone pain, cough and asthenia. Racotumomab-alum cancer vaccine could be considered an effective and safe treatment option as second-line therapy for advanced NSCLC. Further clinical studies should be conducted to confirm this result.

Effects of recombinant human endostatin on therapeutic effect, angiogenesis, tumor cell proliferation and migration in patients with non-small cell lung cancer

Objective:To investigate the effects of recombinant human endostatin on therapeutic effect, angiogenesis, tumor cell proliferation and migration in patients with non-small cell lung cancer.Methods: A total of 100 patients with non-small cell lung cancer treated in our hospital from September 2015 to March 2018 were selected as research subjects.They were randomly divided into observation group and control group, 50 cases in each group.The control group was treated with gemcitabine plus cisplatin, while the observation group was combined with Endostar treatment on the basis of the control group. Observed and compared the expression of the therapeutic effect[including cytokeratin 19 fragment (CYFRA21-1), carcinoembryonic antigen (CEA) and carbohydrate antigen (CA50)], angiogenesis[including vascular endothelial growth factor (VEGF) and hypoxia inducible factor (HIF-1 alpha)], tumor cell proliferation[including insulin-like growth factor (IGF-1) and insulin-like growth factor receptor -7 (IGFBP-7)] and migration[including high mobility group protein AT-hook2 (HMGA2) and high mobility group protein B1 (HMGB1)]in two groups.Results: The two groups showed significant changes in the therapeutic effect, angiogenesis, proliferation and migration of tumor cells. Before treatment, there was no significant difference in all levels between the two groups. After treatment, the levels of CYFRA21-1, CEA, CA50, VEGF, HIF-1a, IGF-1, HMGA2 and HMGB1 in the two groups were significantly lower than those before treatment, while the levels of IGFBP-7 were significantly higher than those before treatment. After treatment, the levels of CYFRA21-1, CEA, CA50, VEGF, HIF-1a, IGF-1, HMGA2 and HMGB1 in the observation group were significantly lower than those in the control group, while the levels of IGFBP-7 were significantly higher than those in the control group. Conclusions: Recombinant human endostatin can enhance the therapeutic effect of non-small cell lung cancer patients, reduce angiogenesis, inhibit tumor cell proliferation and migration.

Water metabolism from lung,spleen and kidney

Water and liquid are the material basis of human metabolism.Traditional Chinese medicine believes that water and liquid metabolism is a very complex process that requires the synergy of the internal organs,but mainly the physiological functions of the lungs,spleen and kidneys.If the function or structure of the spleen,lungs,kidneys,or triple-burner is abnormal,it is easy to cause abnormalities in the body's water metabolism,which in turn leads to the production of pathological products such as damp phlegm.

Effect of Breathing on Exposed Lung Volumes and Doses in Patients with Breast Carcinoma Receiving Radiotherapy

Introduction: This study evaluates the changes in the lung volume (LV) exposed radiation during the breath cycle and whether these volume differences have an effect on both lung and target doses in breast carcinoma patients. Material and Methods: Ten patients with left breast carcinoma underwent breast conservative surgery or mastectomy receiving radiotherapy (RT) (breast or chest wall and regional lymph nodes) were included. For this study, planning computerized tomography (CT) images were obtained during deep inspiration (DI) and end of expiration (EE), besides free breathing (FB) to simulate breath cycles. Three-dimensional conformal or intensity-modulated RT planning was done to obtain dose-volume information using CT series taken FB, DI and EE. The treatment plan was done with FB images and exported to the DI and EE scans and re-calculated. Volume changes and calculated dose differences according to breath cycles were compared. Results: There were significant differences in the whole LV, ipsilateral LV and contralateral LV between FB-DI and EE-DI while no significant difference was seen between FB and EE. V20 was lower during DI than FB and EE but the difference was not significant. There was no significant variation in whole breast dose although significant dose variations were observed in mean MI, supraclaviculary and level III axillary lymph node doses between breath cycles. Conclusion: Breath cycle had no significant effect on whole breast dose although significantly changed regional lymph node doses in patients with breast carcinoma receiving whole breast and regional lymph nodes radio-therapy. V20 dose was lower during DI than FB and EE, but the difference was not significant.
