Laparoscopic vs open surgery for gastric cancer: Assessing time, recovery, complications, and markers

BACKGROUND Gastric cancer(GC)is one of the most common cancers worldwide.Morbidity and mortality have increased in recent years,making it an urgent issue to address.La-paroscopic radical surgery(LRS)is a crucial method for treating patients with GC;However,its influence on tumor markers is still under investigation.The data of 194 patients treated at Chongqing University Cancer Hospital bet-ween January 2018 and January 2019 were retrospectively analyzed.Patients who underwent traditional open surgery and LRS were assigned to the control(n=90)and observation groups(n=104),respectively.Independent sample t-tests andχ2 tests were used to compare the two groups based on clinical efficacy,changes in tumor marker levels after treatment,clinical data,and the incidence of posto-perative complications.To investigate the association between tumor marker levels and clinical efficacy in patients with GC,three-year recurrence rates in the two groups were compared.RESULTS Patients in the observation group had a shorter duration of operation,less in-traoperative blood loss,an earlier postoperative eating time,and a shorter hospital stay than those in the control group(P<0.05).No significant difference was observed between the two groups regarding the number of lymph node dissections(P>0.05).After treatment,the overall response rate in the control group was significantly lower than that in the observation group(P=0.001).Furthermore,after treatment,the levels of carbohydrate antigen 19-9,cancer antigen 72-4,carcinoembryonic antigen,and cancer antigen 125 decreased significantly.The observation group also exhibited a significantly lower incidence rate of postoperative complications compared to the control group(P<0.001).Additionally,the two groups did not significantly differ in terms of three-year survival and recurrence rates(P>0.05).CONCLUSION LRS effectively treats early gastric cancer by reducing intraoperative bleeding,length of hospital stays,and postoperative complications.It also significantly lowers tumor marker levels,thus improving the short-term prognosis of the disease.

Clinical Efficacy of Laparoscopic Radical Colorectal Cancer Treatment for Colorectal Cancer and Its Effect on Immune Function

Objective:To explore the therapeutic effect of laparoscopic radical colorectal cancer treatment in colorectal cancer patients.Methods:A total of 50 colorectal cancer patients treated between August 2018 and August 2023 were randomly divided into two groups:Group A underwent laparoscopic radical colorectal cancer surgery,while Group B received open surgery.Clinical indicators,inflammatory factors,immune function indicators,and complications were compared between the two groups.Results:Group A showed significantly shorter operation times,faster recovery times,and reduced hospital stays compared to Group B.Additionally,Group A had less abdominal drainage and intraoperative bleeding(P<0.05).Levels of interleukin(IL)-4,IL-6,ultrasensitive C-reactive protein(hs-CRP),and tumor necrosis factor-alpha(TNF-α)were lower in Group A compared to Group B(P<0.05).Furthermore,immune function indicators,including CD3+,CD4+,CD8+,and CD4+/CD8+ratios,were better in Group A(P<0.05).The complication rate in Group A was also lower than in Group B(P<0.05).Conclusion:Laparoscopic radical treatment for colorectal cancer is efficient and feasible,causing minimal immune function impairment and inflammatory response.It also shortens postoperative recovery time.

Primary Treatment for Clinically Early Cervical Cancer with Lymph Node Metastasis:Radical Surgery or Radiation?

Objective To compare survival outcomes between primary radical surgery and primary radiation in early cervical cancer.Methods Patient information was extracted from the Surveillance,Epidemiology,and Results database.Patients diagnosed with early cervical cancer of stage T1a,T1b,and T2a(American Joint Committee on Cancer,7th edition)from 1998 to 2015 were included in this study after propensity score matching.Overall survival(OS)was analyzed using the Kaplan-Meier method.Results Among the 4964 patients included in the study,1080 patients were identified as having positive lymph nodes(N1),and 3884 patients were identified as having negative lymph nodes(N0).Patients with primary surgery had significantly longer 5-year OS than those with primary radiotherapy in both the N1 group(P<0.001)and N0 group(P<0.001).In the subgroup analysis,similar results were found in patients with positive lymph nodes of stage T1a(100.0%vs.61.1%),T1b(84.1%vs.64.3%),and T2a(74.4%vs.63.8%).In patients with T1b1 and T2a1,primary surgery resulted in longer OS than primary radiation,but not in patients with T1b2 and T2a2.In multivariate analysis,the primary treatment was identified as an independent prognostic factor in both N1 and N0 patients(HR_(N1)=2.522,95%CI=1.919–3.054,PN1<0.001;HR_(N0)=1.895,95%CI=1.689–2.126,PN0<0.001).Conclusion In early cervical cancer stage T1a,T1b1,and T2a1,primary surgery may result in longer OS than primary radiation for patients with and without lymph node metastasis.

Therapeutic effects of Buzhong Yiqi decoction in patients with spleen and stomach qi deficiency after routine surgery and chemotherapy for colorectal cancer

BACKGROUND According to the theory of traditional Chinese medicine(TCM),the spleen and stomach are the basis of acquired nature and the source of qi and blood biochemistry.After surgery and chemotherapy,patients with colorectal cancer often develop spleen and stomach qi deficiency syndrome,leading to decreased immune function.Buzhong Yiqi decoction,a classic TCM prescription,has the effect of tonifying middle-jiao and invigorating qi,boosting Yang,and suppressing immune-related inflammation.Moreover,it is widely used in the treatment of spleen and stomach qi deficiency syndrome.AIM To investigate the effect of Buzhong Yiqi decoction on spleen and stomach qi deficiency in patients with colorectal cancer.METHODS One hundred patients with colorectal cancer who underwent preoperative chemotherapy and laparoscopy at The First TCM Hospital of Changde from January 2022 to October 2023 were retrospectively analyzed.The patients were divided equally into control and observation groups.Both groups underwent conventional rehabilitation surgery,and the observation group was supplemented with Buzhong Yiqi decoction.SPSS 26.0 was used for statistical analyses.Theχ2 test was used for univariate analysis;independent sample t-tests were used in all cases.RESULTS No significant differences were observed preoperatively in the general characteristics of the two groups.Fourteen days post-surgery,the abdominal distension,emaciation,loose stool,loss of appetite,and vomiting scores were significantly lower in the observation group than in the control group(P<0.05).Immune function and interleukin(IL)-10 levels in the observation group were significantly higher than those of the control group,whereas IL-6,tumor necrosis factor-α,and C-reactive protein levels,tumor biological indexes,and adverse reactions in the observation group were significantly lower than those of the control group(P<0.05).One month after surgery,the patients’quality of life in the observation group was significantly higher than that of the patients in the control group(P<0.05).CONCLUSION Buzhong Yiqi decoction can regulate inflammatory responses and metabolic processes by enhancing immune function,thereby promoting overall immune nutrition and restoring the body’s balance.

Laparoscopic treatment for suspected gallbladder cancer confined to the wall： a 10-year study from a single institution

Objective： Although laparoscopic treatment of gallbladder cancer（GBC） has been explored in the last decade,long-term results are still rare. This study evaluates long-term results of intended laparoscopic treatment for suspected GBC confined to the gallbladder wall, based on our experience over 10 years.Methods： Between August 2006 and December 2015, 164 patients with suspected GBC confined to the wall were enrolled in the protocol for laparoscopic surgery. The process for GBC treatment was analyzed to evaluate the feasibility of computed tomography（CT） and/or magnetic resonance imaging（MRI） combined with frozen-section examination in identifying GBC confined to the wall. Of 159 patients who underwent the intended laparoscopic radical treatment, 47 with pathologically proven GBC were investigated to determine the safety and oncologic outcomes of a laparoscopic approach to GBC.Results： Among the 164 patients, 5 patients avoided further radical surgery because of unresectable disease and12 were converted to open surgery; in the remaining 147 patients, totally laparoscopic treatment was successfully accomplished. Extended cholecystectomy was performed in 37 patients and simple cholecystectomy in 10. The T stages based on final pathology were Tis（n=6）, T1 a（n=2）, T1 b（n=9）, T2（n=26）, and T3（n=4）. Recurrence was detected in 11 patients over a median follow-up of 51 months. The disease-specific 5-year survival rate of these 47 patients was 68.8%, and rose to 85% for patients with a normal cancer antigen 19-9（CA19-9） level.Conclusions： The favorable long-term outcomes demonstrate the feasibility of combined CT/MRI and frozensection examination in the selection of patients with GBC confined to the gallbladder wall, confirm the oncologic safety of laparoscopic treatment in selected GBC patients, and favor measurement of preoperative CA19-9 in the selection of GBCs suitable for laparoscopic treatment.

Development and future perspectives of natural orifice specimen extraction surgery for gastric cancer

In recent years,natural orifice specimen extraction surgery(NOSES),a novel minimally invasive surgical technique,has become a focus in the surgical field,and has been initially applied in gastric surgery in many national medical centers worldwide.In addition,this new surgical technique was launched in major hospitals in China.With an increasing number of patients who have accepted this new surgical technique,NOSES has provided new prospects for the treatment of gastric cancer(GC),which may achieve a better outcome for both patients and surgeons.More and more experts and scholars from different countries and regions are currently paying close attention to NOSES for the treatment of GC.However,there are only a few reports of its use in GC.This review focuses on the research progress in NOSES for radical gastrectomy in recent years.We also discuss the challenges and prospects of NOSES in clinical practice.

Effect of laparoscopic radical resection of colon cancer on immune function, stress response and gastrointestinal hormones in patients with colon cancer

Objective:To investigate the effect of laparoscopic radical resection of colon cancer on immune function, stress response and gastrointestinal hormones in patients with colon cancer. Method:140 patients with colon cancer admitted to a hospital from January 2016 to November 2017 were divided into control group and observation group according to the operation method, 70 cases in each group. The control group was treated with open radical resection of colon cancer, while the observation group was treated with laparoscopic radical resection of colon cancer. The changes of immune function, stress response, visceral protein and gastrointestinal hormone were compared between the two groups before and after treatment.Results:There was no significant difference in immune function, stress response, visceral protein and gastrointestinal hormone between the two groups before operation (P>0.05). The ratio of Th1 cells was decreased, while the ratio of Th2, Th17 and Treg cells was increased in the two groups (P<0.05). The proportion of Th1 cells in the observation group was higher than that in the control group,while the ratio of Th2, Th17 and Treg cells in the observation group was lower than that of the control group (P<0.05). The levels of Cor, E and NE were increased in the two groups (P<0.05). And the levels of Cor, E and NE in the observation group were lower than those in the control group (P<0.05). The levels of PA, TRF and RBP were decreased in the two groups (P<0.05). And PA, TRF and RBP levels were higher in the observation group than in the control group (P<0.05). The GAS, MTL and GIP levels were lower in the two groups (P<0.05). And the GAS, MTL and GIP levels in the observation group were higher than those in the control group (P<0.05).Conclusion: Laparoscopic radical mastectomy has little effect on the immune function of patients. It can alleviate the surgical stress response to a certain extent, which is beneficial to the recovery of gastrointestinal function and can be extended to clinical application.

目的探讨早期宫颈癌术后阴道残端复发危险因素。方法选择2018年1月至2020年3月在河南科技大学第一附属医院接受宫颈癌根治术的243例患者为研究对象,根据术后3 a内是否发生阴道残端复发分为复发组(n=21)和未复发组(n=22)。收集2组患者的年龄、病理类型、宫颈癌国际妇产科联盟(FIGO)分期、组织分化程度、手术方式、手术切缘与肿瘤距离、肌层浸润情况、确诊时有无淋巴结受累、肿瘤出芽数、有无脉管癌栓、阴道切除长度、术后放射治疗部位等临床资料。采用单因素方差分析和二元logistic回归分析早期宫颈癌术后阴道残端复发危险因素。结果早期宫颈癌患者术后3 a内阴道残端复发率为8.64%(21/243)。复发组与未复发组患者的病理类型、手术切缘与肿瘤距离、肌层浸润情况、肿瘤出芽数、阴道切除长度和术后放射治疗部位比较差异有统计学意义(P<0.05);2组患者的年龄、FIGO分期、组织分化程度、手术方式、确诊时有无淋巴结受累、有无脉管癌栓等方面比较差异无统计学意义(P>0.05)。二元logistic回归分析结果显示,手术切缘与肿瘤距离≤3.5 mm、肿瘤出芽数>5个、阴道切除长度≤2 cm是早期宫颈癌术后阴道残端复发的危险因素(P<0.05),术后盆腔放射治疗联合阴道近距离放射治疗是早期宫颈癌术后阴道残端复发的保护性因素(P<0.05)。结论早期宫颈癌术后阴道残端复发风险较高,手术切缘与肿瘤距离≤3.5 mm、肿瘤出芽数>5个、阴道切除长度≤2 cm是早期宫颈癌术后阴道残端复发的危险因素,盆腔放射治疗联合阴道近距离放射治疗可降低早期宫颈癌术后阴道残端复发风险。
