Objective To assess the prevalence of malnutrition in patients with advanced non-small cell lung cancer (NSCLC) using the Global Leadership Initiative on Malnutrition (GLIM) criteria, analyze its associated factors, and explore the adverse effects of malnutrition on advanced NSCLC patients in multiple aspects. Methods Patients with NSCLC who were hospitalized for the first time in the Department of Oncology, Shangjin Hospital, West China Hospital, Sichuan University between January and December 2021 were retrospectively selected as the study objects. Malnutrition assessment was carried out in all patients according to GLIM criteria, and the current situation and related factors of malnutrition were analyzed. The Barthel index scale was used to compare the daily activity ability between the malnourished group and the non-malnourished group, the Quality-of-Life Questionnaire-Core 30 scale was used to compare the quality of life between the two groups, and the adverse reactions of the two groups were compared by the hospital information system course records. Results According to GLIM diagnostic criteria, 134 of 285 patients (47.0%) were diagnosed with malnutrition. The results of binary multiple logistic regression analysis showed that age [60-69 vs. <60 years old: odds ratio (OR)=2.323, 95% confidence interval (CI) (1.277, 4.397); ≥70 vs. <60 years old: OR=10.816, 95%CI (4.185, 27.959)], previous medical history [OR=2.740, 95%CI (1.313, 5.717)], and albumin level [OR=0.905, 95%CI (0.848, 0.965)] were associated with malnutrition in patients with advanced NSCLC (P<0.05). The daily activity ability and quality of life in the malnourished group were significantly worse than those in the non-malnourished group (87.57±12.48 vs. 91.82±6.77, P<0.05; 76.22±11.52 vs. 83.96±9.75, P<0.05), and the incidence of adverse reactions in the malnourished group was higher than that of the non-malnourished group (50.7% vs. 31.8%, P<0.05). Conclusions The prevalence of malnutrition in patients with advanced NSCLC is high, and advanced age, previous medical history and albumin are related factors of malnutrition in patients with advanced NSCLC. Combined malnutrition may have adverse effects on mobility, quality of life and adverse effects of anti-tumor therapy in advanced NSCLC patients.
ObjectiveTo analyze the factors influencing the total number of harvested lymph nodes in laparoscopic radical gastrectomy for advanced gastric cancer.MethodsThe clinicopathologic data of patients who underwent laparoscopic D2 radical resection of gastric cancer in this hospital for advanced gastric cancer from January 2018 to July 2020 were retrospectively analyzed. The statistical analysis was conducted to analyze the influence factors (age, gender, tumor size, tumor site, body mass index, infiltration depth, lymph node metastasis, HER-2 gene amplification status, presence or absence of vascular tumor thrombus, presence or absence of nerve infiltration, differentiation type, pTNM, Borrmann type, and type of gastrectomy) on the number of harvested lymph nodes.ResultsA total of 536 patients met the inclusion and exclusion criteria were included. The results of univariate analysis showed that the total number of harvested lymph nodes during laparoscopic radical gastrectomy for advanced gastric cancer was correlated with age, tumor size, tumor infiltration depth, lymph node metastasis, pTNM stage, Borrmann type, and type of gastrectomy. That was, the younger the patient was (≤ 54 years old), the larger the tumor was (long diameter >3.5 cm), the later the Borrmann classification was (type Ⅲ, Ⅳ), the deeper the tumor invasion was, the more the number of lymph node metastasis was, the later the pTNM stage was, and the more the number of lymph nodes was detected in patients undergoing total gastrectomy (all P<0.05). The multiple linear regression analysis showed that the age, lymph node metastasis, and PTNM stage had significant effects on the number of harvested lymph nodes. The multiple linear regression model was statistically significant (F=6.754, P<0.001). 11.2% of the variation in the number of harvested lymph nodes could be explained by the age, lymph node metastasis, and pTNM stage (adjusted R2=11.2%). ConclusionsNumber of harvested lymph nodes in laparoscopic radical gastrectomy for advanced gastric cancer is greatly affected by the age of patients, lymph node metastasis, and pTNM stage. So patients should be evaluated objectively and individually according to their age so as to harvest sufficient number of lymph nodes, which is conducive to accurately judge pTNM stage, formulate accurate adjuvant treatment scheme, and improve prognosis of patients.
ObjectiveTo assess the outcomes of laparoscopy-assisted surgery for treatment of advanced gastric cancer.MethodsA total of 115 patients with advanced gastric cancer were included between January 2014 and December 2018 were analyzed retroprospectively, the patients were divided into two groups: open surgery group (OS group, n=63) and laparoscopy-assisted surgery group (LAS group, n=52). Baseline characteristics, intraoperative parameters and postoperative items, and long-term efficacy were compared between the two groups.ResultsThere was no significant difference in preoperative baseline data including gender, age and preoperative serum parameters between the two groups (P>0.05). Intraoperative blood loss in the LAS group was significantly less than that in the OS group (P<0.05). In addition, the first feeding time after operation and postoperative hospital stay in the LAS group were significantly shorter than the OS group (P<0.05). Furthermore, numbers of white blood cells and neutrophils in the LAS group were fewer than that in the OS group at postoperative 2 days (P<0.05); the level of serum albumin in the LAS group was higher than that OS group (P<0.05). The number of lymph nodes detected during operation in the LAS group was more than that in the OS group (P<0.05). Operative time and occurrence of postoperative complications were not statistically significant between the two groups (P>0.05). One hundred and ten of 115 patients were followed- up, the follow-up rate was 95.7%. The follow-up time ranged from 6 to 48 months, with a median follow-up time of 12.4 months. The disease-free survival time of the OS group was 12.2±6.5 months, while that of the LAS group was 13.5±7.4 months. There was no significant difference between the two groups (P>0.05).ConclusionsLaparoscopic technique in treatment of advanced gastric cancer has the minimally invasive advantage, less intraoperative blood loss, less surgical trauma, and faster postoperative recovery in comparing to the traditional open surgery. Also the lymph node dissection is superior to open surgery. The curative effect is comparable to that of open surgery.
ObjectiveTo compare the clinical recovery and immune response between laparoscopic-assisted and open D2 gastrectomy for advanced gastric cancer. MethodsThe clinical data of 53 patients with advanced gastric cancer from January 2012 to October 2013 were studied prospectively. According to random number table, patients were randomly divided into laparoscopic-assisted group(LA group, n=27) and open operation group(OO group, n=26). Operative time, blood loss, time to passage of flatus, time to resume soft diet, after bed time, postoperative hospital stay, and number of retrieved lymph nodes were compared respectively between the two groups. The changes in CD3, CD4+, CD8+, IgG, IgA, IgM, and CRP were examined respectively by using flow cytometry and immunoturbidimetric assays on the preoperative day 1, and on the postoperative day 1 and 7. ResultsThe operative time was longer significantly in LA group than that in OO group(P < 0.05). The mean blood loss, the first flatus time, after bed time, and postoperative hospital stay in the two groups were all different statistically(P < 0.05), and all were better in LA group. However, the mean number of retrieved lymph nodes and the time to resume soft diet were not significantly different in the two groups(P > 0.05). On the day 1 and 7 after operation, the CD3, CD4+, and CD8+ significantly decreased as compared with those preoperatively in two groups(P < 0.01, P < 0.05). On the day 1 after operation, the levels of IgG, IgA, and IgM significantly decreased as compared with those preoperatively in two groups(P < 0.05). Those immunoglobulin in LA group recovered to close to the level before surgery, but in OO group sustained lower level(P < 0.05). On the day 1 and 7 after operation, CRP level significantly increased as compared with those preoperatively in two groups(P < 0.01, P < 0.05). Those changes of above index were not significantly different between the LA group and OO group on the day 1 after operation(P > 0.05). All index recovered gradually in the two groups on the day 7 after operation and were better in LA group(P < 0.05, except IgA). ConclusionLaparoscopic radical gastrectomy for advanced gastric cancer resulted in a quicker clinical recovery and a lesser depression to the perioperative cellular and humoral immune function.
ObjectiveTo evaluate the therapeutic effect and adverse reaction of paclitaxel liposome combined with continuous infusion of large-dose 5-fluorouracil(5-fu) in treatment for advance gastric cancer(AGC). MethodsFrom May 2009 to August 2012, 63 consecutive patients with AGC in this hospital were enrolled in this study. All the patients were given chemotherapy including paclitaxel liposome and continuous infusion of large-dose(2.5 g/m2) 5-fu. The efficacy and toxicity of this regimen were observed. ResultsThere was no patient who could not tolerate adverse reaction related to such regimen. Five cases achieved complete response and 31 cases achieved partial response, the overall response rate was 57.1%(36/63). Hematologic toxicity included gradeⅢ/Ⅳleucopenia 8 cases(12.7%) and neutropenia 10 cases(15.9%), while there was no occurrence of gradeⅢ/Ⅳanemia or thrombopenia. Non-hematologic toxicity was fairly mild. ConclusionsPaclitaxel liposome is safe, well tolerated, highly targeted, and has long duration of effect. Paclitaxel liposome combined with continuous infusion of large-dose 5-fu is safe and effective in treatment for patients with AGC.
ObjectiveTo study value of long noncoding RNA H19 and HOTTIP in plasma in predicting efficacy of neoadjuvant chemotherapy (NAC) for resectable locally advanced gastric cancer. MethodsForty patients with T3–4aN+M0 gastric cancer and 40 patients with benign gastric diseases treated in the Yantai Yuhuangding Hospital Affiliated to Qingdao University from August 2020 to May 2021 were prospectively included. The expressions of H19 and HOTTIP in the plasma of gastric cancer and benign gastric diseases patients without any treatment after admission were detected before treatment (CAPEOX regimen was used in the patients with gastric cancer), then which were detected after 2 NAC courses for patients with gastric cancer. Meanwhile, some clinical items were detected and the efficacy of NAC was evaluated. The complete remission (CR) and partial remission (PR) were classified as objective remission, CR, PR, and disease stability were classified as disease control. The expressions of H19 and HOTTIP between the different patients were compared and the receiver operating characteristic (ROC) curve was used to evaluate their values in the diagnosis of resectable locally advanced gastric cancer. ResultsThere were 13 cases of T downstaging and 27 cases of T non-downstaging and 25 cases of objective remission and 35 disease control after NAC. The median relative expression levels of H19 and HOTTIP before NAC in the patients with gastric cancer were higher than those in the patients with benign gastric diseases (H19: 1.42 versus 0.98, Z=–3.835, P<0.001; HOTTIP: 2.15 versus 1.04, Z=–5.062, P<0.001), and which were in the patients with T downstaging and disease control were lower than those in the patients with T non-downstaging and 5 cases of disease progression (For T staging, H19: 1.12 versus 1.54, Z=–2.960, P=0.002; HOTTIP: 1.49 versus 2.30, Z=–2.310, P=0.019. For efficacy of NAC, H19: 1.39 versus 2.48, Z=–3.211, P<0.001; HOTTIP: 1.96 versus 3.25, Z=–2.393, P=0.014). The median relative expressions of H19 and HOTTIP after NAC were lower than those before NAC in the patients with gastric cancer (H19: 1.12 versus 1.42, Z=–3.965, P<0.001; HOTTIP: 1.30 versus 2.15, Z=–4.839, P<0.001). There were no significant differences in the changes of H19 and HOTTIP before and after NAC between the patients with T downstaging and T non-downstaging, and between disease control and disease progression (P>0.05). The areas of ROC curve of H19, HOTTIP, and combination of H19 and HOTTIP in diagnosis of resectable locally advanced gastric cancer were higher than 0.7. ConclusionsLncRNA H19 and HOTTIP might be potential tumor markers in gastric cancer, and their diagnostic values for resectable locally advanced gastric cancer are higher. Gastric cancer patients with low expressions of H19 and HOTTIP in plasma might be more sensitive to NAC.
Objective To investigate the clinical effects and safety differences of open surgery and laparoscopy primary lesion resection combined with D2 lymph node dissection in the treatment of elderly patients with advanced gastric cancer. Methods One hundred and forty elderly patients with advanced gastric cancer were chosen and randomly divided into two group including open operative group (70 patients) with primary lesion resection combined with D2 lymph node dissection by open operation and laparoscopic surgery group (70 patients) with primary lesion resection combined with D2 lymph node dissection by laparoscopy; and the operative time, intraoperative bleeding amount, the levels of PaCO2 in operation, liquid diet eating time, postoperative anal exhaust time, postoperative gastric tube indwelling time, postoperative ambulation time, the level of haemoglobin (Hb) after operation, the hospitalization time, the number of lymph node dissection, the survival rate with followed-up and postoperative complication incidence of both groups were compared. Results There was no significant difference in the operative time between 2 groups (P>0.05). The intraoperative bleeding amount, the level of PaCO2 in operation, liquid diet eating time, postoperative anal exhaust time, postoperative gastric tube indwelling time, postoperative ambulation time, the level of Hb after operation and the hospitalization time of laparoscopic surgery group were significantly better than open operative group (P<0.05). The level of PaCO2 in operation of laparoscopic surgery group was significantly higher than open operative group (P<0.05). There were no significant difference in the gastric lymph node dissection number and the peripheral lymph node dissection number of gastric artery between 2 groups (P>0.05). There were no significant difference in the survival rates between the 2 groups after 3-year followed-up (P>0.05). The complication incidence after operation of laparoscopic surgery group was significantly lower than open operative group (P<0.05). The quality of life scores of patients in laparoscopic surgery group were significantly higher than those in open operative group on 7 days and in 3 months after operation, and the difference were statistically significant (P<0.05). Conclusion Compared with open operation, primary lesion resection combined with D2 lymph node dissection by laparoscopy in the treatment of elderly patients with advanced gastric cancer can efficiently possess the advantages including minimally invasive, shorter recovery time and less postoperative complications.
Objectives To evaluate the clinical effectiveness and safety of combined induction therapy of interferon (IFN) with chemotherapy for survival of the patients with advanced non-small cell lung cancer (NSCLC) by meta-analysis. Methods All clinical trials of addition of IFN plus chemotherapy versus chemotherapy alone for induction therapy to advanced NSCLC patients in MEDLINE (1966-2006), EMBASE (1984-2006.1) and The Cochrane Library (Issue 1,2006) were identified. The references of related studies and Education Books of ASCO and ESMO meeting were handsearched. The quality of included trials was evaluated. Data were extracted by two reviewers independently with a designed extraction form. RevMan 4.2.7 software was used for data analysis. Results Five randomized controlled trials involving 360 patients were included. The pooled result of 3 studies showed that IFN plus chemotherapy induction treatment did not improve 1-year survival rate with RR 0.76, 95%CI 0.46 to 1.26. The pooled result of 5 studies showed that IFN plus chemotherapy induction treatment did not improve response rate with RR 1.40, (0.83 2.34). The pooled result showed that IFN plus chemotherapy induction treatment might significantly increase leukopenia and thrombocytopenia with RR 2.61,95%CI1.70 to 3.99) and RR 4.78,95%CI 1.87 to 12.19 respectively . Conclusion Insufficient data exists to state whether IFN plus chemotherapy induction treatment can improve 1-year survival rate and response rate. IFN plus chemotherapy may increase occurrence of leucopenia and thrombocytopenia. Further studies are warranted.
Objective To explore the clinical value, latest research progress, and clinical controversy of total neoadjuvant therapy (TNT) in locally advanced rectal cancer (LARC). Method We searched and reviewed on the latest literatures about studies of the clinical research of TNT in LARC. Results TNT could make the tumor downstage rapidly and improve the patients’ treatment compliance. In terms of organ preservation rate, 3-year disease-free survival and pathological complete remission rate, TNT had advantages and was a especial potential treatment strategy compared with traditional methods. Conclusions TNT decreases local recurrence rate and improves the long-term survival. For LARC patients with strong desire for organ preservation, TNT is a good treatment choice and has the value of clinical promotion.
ObjectiveTo summarize the research progress of preoperative regional-arterial chemotherapy in advanced gastric cancer. MethodThe literatures about the research progress of preoperative regional-arterial chemotherapy in the advanced gastric cancer were reviewed. ResultsThe preoperative regional-arterial chemotherapy in the advanced gastric cancer could decrease the tumour stage, improve the R0 resection rate and the long-term survival rate, effectively improve the drug concentrations of tumor and portal vein, and not only kill or damage cancer cells directly, but also prevent the metastasis of liver and lymph nodes effectively, and reduce the side effects, cause the nuclear pyknosis and fracture of cancer cells in a short time. The course of preoperative regional-arterial chemotherapy in the advanced gastric cancer generally was 4-9 weeks, and then whether the surgery treatment was decided to undergo according to the results of the curative effect evaluation. ConclusionsThe preoperative regional-arterial chemotherapy in the advanced gastric cancer has more advantages than intravenous chemotherapy, further research of multicenter and large clinical trials, would inaugurate a wider application prospects.
