Predictors of disease recurrence after radical resection and adjuvant chemotherapy in patients with stage IIb-IIIa squamous cell lung cancer:A retrospective analysis

BACKGROUND Lung cancer(LC)is a global medical,social and economic problem and is one of the most common cancers and the leading cause of mortality from malignant neoplasms.LC is characterized by an aggressive course,and in the presence of disease recurrence risk factors,patients,even at an early stage,may be indicated for adjuvant therapy to improve survival.However,combined treatment does not always guarantee a favorable prognosis.In this regard,establishing predictors of LC recurrence is highly important both for determining the optimal treatment plan for the patients and for evaluating its effectiveness.AIM To establish predictors of disease recurrence after radical resection and adjuvant chemotherapy in patients with stage IIb-IIIa lung squamous cell carcinoma(LSCC).METHODS A retrospective case-control cohort study included 69 patients with LSCC who underwent radical surgery at the Orenburg Regional Clinical Oncology Center from 2009 to 2018.Postoperatively,all patients received adjuvant chemotherapy.Histological samples of the resected lung were stained with Mayer's hematoxylin and eosin and examined under a light microscope.Univariate and multivariate analyses were used to identify predictors associated with the risk of disease recurrence.Receiver operating characteristic curves were constructed to discriminate between patients with a high risk of disease recurrence and those with a low risk of disease recurrence.Survival was analyzed using the Kaplan-Meier method.The log-rank test was used to compare survival curves between patient subgroups.Differences were considered to be significant at P<0.05.RESULTS The following predictors of a high risk of disease recurrence in patients with stage IIb-IIa LSCC were established:a low degree of tumor differentiation[odds ratio(OR)=7.94,95%CI=1.08-135.81,P=0.049];metastases in regional lymph nodes(OR=5.67,95%CI=1.09-36.54,P=0.048);the presence of loose,fine-fiber connective tissue in the tumor stroma(OR=21.70,95%CI=4.27-110.38,P=0.0002);and fragmentation of the tumor solid component(OR=2.53,95%CI=1.01-12.23,P=0.049).The area under the curve of the predictive model was 0.846(95%CI=0.73-0.96,P<0.0001).The sensitivity,accuracy and specificity of the method were 91.8%,86.9%and 75.0%,respectively.In the group of patients with a low risk of LSCC recurrence,the 1-,2-and 5-year disease-free survival(DFS)rates were 84.2%,84.2%and 75.8%,respectively,while in the group with a high risk of LSCC recurrence the DFS rates were 71.7%,40.1%and 8.2%,respectively(P<0.00001).Accordingly,in the first group of patients,the 1-,2-and 5-year overall survival(OS)rates were 94.7%,82.5%and 82.5%,respectively,while in the second group of patients,the OS rates were 89.8%,80.1%and 10.3%,respectively(P<0.00001).CONCLUSION The developed method allows us to identify a group of patients at high risk of disease recurrence and to adjust to ongoing treatment.

Radical cholecystectomy without liver resection for peritoneal side early incidental gallbladder cancer

Gallbladder cancer(GBC)is a rare disease with a poor prognosis.Simple cholecystectomy may be an adequate treatment only for very early disease(Tis,T1a),whereas reoperation is recommended for more advanced disease(T1b and T2).Radical cholecystectomy should have two fundamental objectives:To radically resect the liver parenchyma and to achieve adequate clearance of the lymph nodes.However,recent studies have shown that compared with lymph node dissection alone,liver resection does not improve survival outcomes.The oncological roles of lymphadenectomy and liver resection is distinct.Therefore,for patients with incidental GBC without liver invasion,hepatic resection is not always mandatory.

Impact of thoracic paravertebral block and sufentanil on outcomes and postoperative cognitive dysfunction in thoracoscopic lung cancer surgery

BACKGROUND Postoperative pain management and cognitive function preservation are crucial for patients undergoing thoracoscopic surgery for lung cancer(LC).This is achieved using either a thoracic paravertebral block(TPVB)or sufentanil(SUF)-based multimodal analgesia.However,the efficacy and impact of their combined use on postoperative pain and postoperative cognitive dysfunction(POCD)remain unclear.AIM To explore the analgesic effect and the influence on POCD of TPVB combined with SUF-based multimodal analgesia in patients undergoing thoracoscopic radical resection for LC to help optimize postoperative pain management and improve patient outcomes.METHODS This retrospective analysis included 107 patients undergoing thoracoscopic radical resection for LC at The Affiliated Cancer Hospital of Zhengzhou University and Henan Cancer Hospital between May 2021 and January 2023.Patients receiving SUF-based multimodal analgesia(n=50)and patients receiving TPVB+SUF-based multimodal analgesia(n=57)were assigned to the control group and TPVB group,respectively.We compared the Ramsay Sedation Scale and visual analog scale(VAS)scores at rest and with cough between the two groups at 2,12,and 24 h after surgery.Serum levels of epinephrine(E),angio-tensin Ⅱ(Ang Ⅱ),norepinephrine(NE),superoxide dismutase(SOD),vascular endothelial growth factor(VEGF),transforming growth factor-β1(TGF-β1),tumor necrosis factor-α(TNF-α),and S-100 calcium-binding proteinβ(S-100β)were measured before and 24 h after surgery.The Mini-Mental State Examination(MMSE)was administered 1 day before surgery and at 3 and 5 days after surgery,and the occurrence of POCD was monitored for 5 days after surgery.Adverse reactions were also recorded.RESULTS There were no significant time point,between-group,and interaction effects in Ramsay sedation scores between the two groups(P>0.05).Significantly,there were notable time point effects,between-group differences,and interaction effects observed in VAS scores both at rest and with cough(P<0.05).The VAS scores at rest and with cough at 12 and 24 h after surgery were lower than those at 2 h after surgery and gradually decreased as postoperative time increased(P<0.05).The TPVB group had lower VAS scores than the control group at 2,12,and 24 h after surgery(P<0.05).The MMSE scores at postoperative days 1 and 3 were markedly higher in the TPVB group than in the control group(P<0.05).The incidence of POCD was significantly lower in the TPVB group than in the control group within 5 days after surgery(P<0.05).Both groups had elevated serum E,Ang Ⅱ,and NE and decreased serum SOD levels at 24 h after surgery compared with the preoperative levels,with better indices in the TPVB group(P<0.05).Marked elevations in serum levels of VEGF,TGF-β1,TNF-α,and S-100β were observed in both groups at 24 h after surgery,with lower levels in the TPVB group than in the control group(P<0.05).CONCLUSION TPVB combined with SUF-based multimodal analgesia further relieves pain in patients undergoing thoracoscopic radical surgery for LC,enhances analgesic effects,reduces postoperative stress response,and inhibits postoperative increases in serum VEGF,TGF-β1,TNF-α,and S-100β levels.This scheme also reduced POCD and had a high safety profile.

Effect of dexmedetomidine on immune function, hemodynamics and stress response in elderly patients undergoing thoracoscopic radical resection of lung cancer

Objective:To investigate the effects of dexmedetomidine on immune function, hemodynamics and stress response in elderly patients undergoing thoracoscopic radical resection of lung cancer Methods: 80 elderly patients who was underwent radical thoracoscopic lung cancer surgery from September 2016 to February 2018 were selected. According to the anesthesia method, it was divided into the conventional group and the observation group, 40 cases in each group. The conventional group was anesthetized with propofol, midazolam, sufentanil, and atracurium sulfonate. The observation group was anesthetized with dexmedetomidine on the basis of the conventional group. The changes of vascular dynamics were compared between the two groups before induction (T0), induction 5 min (T1), surgery (T2), extubation immediately (T3) and 5 min after extubation (T4). The changes of immune function, inflammation and stress index in T0, T2 and 24h (T5) were compared between the two groups.Results: There were no significant differences in T0 vascular kinetics, immune function and inflammation stress between the two groups (P<0.05). Compared with T0, MAP, HR and CVP were significantly increased in the conventional group at T3 and T4 (P<0.05), and MAP, HR and CVP were significantly increased in the observation group at T3 (P<0.05). Compared with the conventional group in T3, T4, the MAP, HR, and CVP levels in the observation group at T3 and T4 were significantly lower than the conventional group (P<0.05). Compared with T0, the levels of immune function IgG, IgA, IgM and NK in T2 and T5 were significantly lower in the two groups (P<0.05). There was no significant difference in IgG, IgA, IgM and NK levels between T2 and T5 in the two groups (P>0.05). Compared with T0, the stress levels of NE and E were significantly increased at T2, and the levels of inflammatory factors TNF-αand Cor were significantly increased at T2 and T5 (P<0.05). Compared with the conventional group at T2, the NE and E levels in the observation group were significantly lower than those in the conventional group (P<0.05), and the levels of TNF-α and Cor in the observation group were significantly lower than those in the conventional group at T2 and T5 (P<0.05).Conclusions: Dexmedetomidine anesthesia has little effect on perioperative hemodynamics in elderly patients undergoing thoracoscopic lung cancer radical resection, and can relieve stress response, so it is worthy of clinical application.

Analysis of factors related to postoperative pulmonary infection in lung cancer patients after recovery from COVID-19

Objective:To explore factors related to postoperative pulmonary infection in lung cancer patients after recovery from COVID-19 and to provide methods for preventing and reducing the incidence of postoperative lung infection in patients with lung cancer.Methods:A total of 92 patients who underwent lung cancer surgery in the Department of Thoracic and Cardiac Surgery of Yichang Central People’s Hospital from January 28,2023,to March 3,2023,were selected.They were divided into a pulmonary infection group(47 cases)and a nonpulmonary infection group(45 cases)according to whether pulmonary infection occurred.General clinical data of patients were collected and collated to analyse the related influencing factors of pulmonary infection in lung cancer patients after recovery from COVID-19.Results:Univariate analysis showed that patient age(≥60 years),fever after COVID-19 infection,oral and laryngeal symptoms,digestive tract symptoms,neurological symptoms,long-term smoking history,hypertension history,and operation time(≥3 h)were correlated with pulmonary infection(all P<0.05).There was no significant correlation between postoperative pulmonary infection and sex,ocular,nasal and tongue symptoms,systemic symptoms,duration of COVID-19,COPD,lobectomy site,incision pain,mechanical ventilation time(≥6 h),drainage tube retention time(3 d),surgical method(P>0.05).Logistic multivariate analysis showed that age(≥60 years old),long operation time(≥3 h)and long-term smoking history were independent influencing factors for postoperative pulmonary infection in patients with radical resection of lung cancer(P>0.05).Conclusion:In this study,older age(≥60 years old),long-term smoking history,and long operation time(≥3 h)were risk factors for pulmonary infection after lung cancer surgery.In the future,active treatment measures can be taken to address these risk factors during the perioperative period to reduce the incidence of postoperative pulmonary infection.

Advances and controversies in the management of early stage nonsmall cell lung cancer

Complete resection continues to be the gold standard for the treatment of earlystage lung cancer.The landmark Lung Cancer Study Group trial in 1995 established lobectomy as the minimum intervention necessary for the management of early-stage non-small cell lung cancer,as it was associated with lower recurrence and metastasis rates than sublobar resection and lower postoperative morbidity and mortality than pneumonectomy.There is a growing tendency to perform sublobar resection in selected cases,as,depending on factors such as tumor size,histologic subtype,lymph node involvement,and resection margins,it can produce similar oncological results to lobectomy.Alternative treatments such as stereotactic body radiotherapy and radiofrequency ablation can also produce good outcomes in inoperable patients or patients who refuse surgery.

Results: Intra group level comparison, compared with the levels of two groups at the T0 moment, the levels of TNF-α, CRPand NE of theT1 and T2 moment were significantly increased, the level of PaO2 were significantly decreased, and T2 moment levels were significantly higher than that of T1 moment, the difference was statistical significance;There were no significant differences between the two groups of the levels of TNF-α, CRP, PaO2, E and NE of the T0 moment, the levels of TNF-α, CRP, E and NE of the observation group at the T1 and T2 moment were significantly lower than the control group, at the same time the PaO2 level was significantly higher than the control group, the difference was statistically significant;There were no statistically significant differences in PaCO2 levels between groups and at any time. Conclusion: Dexmedetomidine combined with parecoxib sodium can effectively relieve the inflammatory stress, improve the levels of the blood gas analysis index and stress hormone during one lung ventilation, has an important clinical value.

Clinical Observation of Breast Conserving Surgery and Modified Radical Mastectomy in the Treatment of Early Breast Cancer

The purpose of the study was to compare the clinical efficacy of breast conserving surgery and modified radical mastectomy in the treatment of early breast cancer.Firstly,the clinical data of 74 patients with early breast cancer treated in our hospital from June 2015 to June 2016 were retrospectively analyzed.Among them,37 patients treated with breast-conserving surgery were set as the study group,and 37 patients treated with modified radical surgery were set as the control group,and the therapeutic effects of the two groups were compared.The results showed that compared with the control group,the incision length,intraoperative blood loss,operation time and hospital stay time were better in the study group,and the excellent and good rate of postoperative breast beauty was higher,with statistically significant differences(P<0.05).There were no statistically significant differences in distant metastasis rate,local recurrence rate,axillary lymph node recurrence rate and fatality rate between the two groups(P>0.05).Therefore,breast-conserving surgery and modified radical surgery have better efficacy in the treatment of early breast cancer,but breast-conserving surgery has more advantages,such as smaller incision,less intraoperative blood loss,shorter operative time and hospital stay,and better postoperative aesthetic effect,which can be used as the first choice for early breast cancer.

Effect of Goal-Directed Fluid Therapy on Lung Function, Cognitive Function and Inflammatory Response in Patients Undergoing Radical Esophageal Cancer Surgery under One-Lung Ventilation

Objective: To explore the effects of goal-directed fluid therapy (GDFT) on lung function, cognitive function and inflammatory response in patients undergoing radical esophageal cancer surgery under one-lung ventilation. Methods: Sixty-seven patients undergoing radical esophageal cancer surgery were divided into GDFT group (GDFT therapy) and control group (conventional liquid therapy). The changes in patients’ pulmonary function, cognitive function and inflammatory response were evaluated. Results: Both alveolar-arterial oxygen partial pressure difference [P(A-a)O2] and respiratory index (RI) increased at one-lung ventilation for 30 minutes (T2) and decreased at one-lung ventilation for 60 minutes (T3), and after surgery (T4) in the two groups, and the GDFT group was lower than the control group (P < 0.05);theoxygenation index (OI) of the two groups decreased at T2, T3, and T4 compared with that at T1 (before one-lung ventilation), and the GDFT group was higher than the control group (P < 0.05). At T4 and T5, the tumor necrosis factor α (TNF-α), interleukin 6 (IL-6), central nervous system specific protein (S100β), and neuron specific enolase (NSE) in the GDFT group were lower compared to the control group (P < 0.05), while interleukin-10 (IL-10) was higher compared to the control group (P < 0.05);the incidence of perioperative neurocognitive disorder (PND) in the GDFT group was lower than that in the control group (P < 0.05). Conclusion: GDFT can help prevent lung injury during radical esophageal cancer surgery under one-lung ventilation, reduce the body’s inflammatory response, and reduce the incidence of perioperative cognitive disorder to a certain extent.

早期直肠癌的诊治现状与全程监测

早期直肠癌是指浸润深度局限于黏膜及黏膜下层的任意大小的直肠上皮性肿瘤,无论有无淋巴结转移。不伴局部淋巴结转移的早期直肠癌,局部切除是主要治疗方式之一。内镜黏膜切除术(EMR)、内镜黏膜下剥离术(ESD)、经肛门内镜显微手术(TEM)和经肛门微创手术(TAMIS)等技术的发展,给早期直肠癌的治疗带来了更多的选择。8%~12%的早期直肠癌病人存在局部淋巴结转移,因此仍需接受全直肠系膜切除术(TME)。现行指南推荐,具有高危病理特征的早期直肠癌需追加补救性根治手术。各种微创、低位保肛手术如经自然腔道取标本手术(NOSES)、经肛门全直肠系膜切除术(TaTME)、经括约肌间切除术(ISR)、适形切除功能保肛手术(CSPO)更好地实现了保肛保功能的目标。早期直肠癌总体预后良好,但其全程监测随诊同样重要。早期直肠癌的早诊早治及全程监测理念的革新,内镜技术及外科技术的发展,必将进一步提高早期直肠癌诊疗的规范化。
