RESUMEN
Objective:To investigate the effect of the duration of preoperative biliary drainage on postoperative complications after pancreaticoduodenectomy.Methods:The clinical data of 102 patients with benign and malignant hepatopancreatic ductal periampullary tumors who underwent pancreaticoduodenectomy and preoperative biliary drainage in Beijing Friendship Hospital, Capital Medical University from January 2016 to July 2020 were retrospectively analyzed. According to the median duration of preoperative biliary drainage, the patients were divided into short-term drainage group (≤ the median duration of biliary drainage) and long-term drainage group (> the median duration of biliary drainage). The general data, the effect of biliary drainage, inflammation-related indicators and postoperative complications were compared between the two groups. Multivariate logistic regression was used to screen the risk factors related to the postoperative severe complications.Results:Of the 102 patients, 68 (66.7%) were males and 34 (33.3%) were females, with a median age of 63 years (43-80 years). The median duration of preoperative biliary drainage was 14 d. There were 68 patients in short-term drainage group and 34 patients in long-term drainage group. There were no statistically significant differences in age, gender, body mass index (BMI), hypertension, diabetes mellitus, surgery history of upper abdominal, American Society of Anesthesiologists (ASA) grade, carcinoembryonic antigen, carbohydrate antigen 125, alpha-fetoprotein, prothrombin time, pancreaticojejunostomy method, operation time, and pathological type between the two groups (all P > 0.05). However, patients in long-term drainage group had higher conversion rate, more blood loss and longer hospital stay compared with those in short-term drainage group (all P < 0.05). Before biliary drainage, alanine aminotransferase (ALT) level in short-term drainage group was higher than that in long-term drainage group ( Z = -2.59, P = 0.009), and there were no statistically significant differences in aspartate aminotransferase (AST), albumin (ALB), total bilirubin (TB) and direct bilirubin (DB) levels between the two groups before biliary drainage (all P > 0.05). After biliary drainage, DB in short-term drainage group was higher than that in long-term drainage group ( Z = -3.34, P = 0.001), and there was no statistically significant difference in ALT, AST, ALB, TB levels between the two groups (all P > 0.05). There were no statistically significant differences in the levels of white blood cells, neutrophils, lymphocytes and the ratio of neutrophils to lymphocytes between the two groups on the 1st and 3rd day after the operation (all P > 0.05). The total incidence of postoperative related complications in short-term drainage group and long-term drainage group was 63.2% (43/68), 70.6% (24/34), respectively, and the difference was statistically significant ( χ2 = 0.54, P = 0.461); the incidences of bile leakage, abdominal or gastrointestinal bleeding, intra-abdominal infection, delayed gastric emptying, all grades of pancreatic leakage, grade B and C pancreatic leakage were not statistically different between the two groups (all P > 0.05); the incidence of severe postoperative related complications in short-term drainage group was higher than that in long-term drainage group [27.9% (19/68) vs. 8.8% (3/34), χ2 = 4.90, P = 0.027]. Multivariate logistic regression analysis showed that the long-term preoperative biliary drainage was an independent protective factor for postoperative severe complications (long-term drainage vs. short-term drainage: OR = 0.253, 95% CI 0.066-0.975, P = 0.046), while BMI ( OR = 1.174, 95% CI 0.986-1.398, P = 0.071) and pathological type (benign or borderline vs. malignant tumor: OR = 0.247, 95% CI 0.043-1.419, P = 0.117) were not independent influencing factors for postoperative severe complications. Conclusions:Short-term biliary drainage (≤14 d) is a risk factor for postoperative severe complications in patients with hepatopancreatic ductal periampullary tumor undergoing preoperative biliary drainage. Preoperative biliary drainage time is not associated with postoperative total complications, pancreatic leakage, bile leakage, abdominal or gastrointestinal bleeding, intra-abdominal infection, delayed gastric emptying.
RESUMEN
Objective:To explore the relationship between the occurrence and development of colorectal cancer and the risk of BRCA1 and BRCA2 gene mutations. Methods:Sixty-one patients with colorectal adenocarcinoma admitted to Beijing Friendship Hospital Affiliated to Capital Medical University from January 2022 to March 2022 were tested by second-generation sequencing. Information such as age of onset, gender, histological grade and TNM stage were collected. According to whether the BRCA1 and BRCA2 gene had systemic mutation, the patients were divided into BRCA1 and BRCA2 gene system mutation group and unmutated group. There were 8 cases in the BRCA1 and BRCA2 gene system mutant group and 53 cases in the non-mutant group. The main outcome measures were the relationship between pathogenic or likely pathogenic germline mutations in colorectal cancer and clinicopathological data of patients, including age of onset, gender, tumor location, TNM stage, histological differentiation, and family history. The secondary outcome was the relationship between BRCA1 and BRCA2 gene system mutations and clinicopathological data. Measurement data with normal distribution were expressed as mean±standard deviation ( ± s), and comparison between groups was analyzed using the t-test. Measurement data with non-normal distribution were represented as M ( Q1, Q3), and comparison between groups was analyzed using the Mann-Whitney U test. Measurement data were expressed as the number of cases or percentage (%), and Chi-square test was used for comparison between groups. Results:Among 61 colorectal adenocarcinoma patients, the frequency of pathogenic or potentially pathogenic germ line mutations in colorectal cancer was 13.1% (8/61), and the frequency of BRCA1 and BRCA2 mutations was 3.3% (2/61). The frequency of BRCA1 and BRCA2 mutations was 13.1% (8/61). Women with BRCA1 and BRCA2 mutations (75.0% vs 37.7%, χ2=3.947, P=0.047) and right colon cancer (75.0% vs 26.4%, χ2=7.889, P=0.019) were significantly higher than those without mutation. Conclusions:The frequency of BRCA1 and BRCA2 gene mutation is higher in colorectal cancer patients. BRCA1 and BRCA2 gene mutations are recommended for colorectal cancer patients with a family history of breast or ovarian cancer.
RESUMEN
Objective:To investigate the association between cancer fatalism and optimistic attitudes among colorectal cancer patients, and how the above linkage is moderated by the involvement of patients′ opinions, the family members′ opinions and the physicians′ opinions in treatment decision-making.Methods:A cross-sectional survey was conducted on 64 patients diagnosed with colorectal cancer and awaiting radical colorectal cancer surgery in the Department of General Surgery of Beijing Friendship Hospital Affiliated to Capital Medical University, from January 2021 to December 2021. There were 38 males and 26 females, aged (61.2±13.0) years from 30 to 84 years. Cancer fatalism, optimism attitudes, and the involvement of patients′ opinions, the family members′ opinions and the physicians′ opinions in treatment decision-making were assessed. The patients′ cancer fatalism beliefs were measured by the " Chance" subscale of the Form C of the Multidimensional Health Locus of Control (MHLC-C), optimism attitudes were assessed by the Chinese version of the revised Life Orientation Test (CLOT-R), and the influence of patients′, family members′, and physicians′ opinions in the medical decision-making process was measured by a self-designed single factor scale. Measurement data of normal distribution were expressed as mean±standard deviation ( ± s). Measurement data of skewed distribution were expressed as M( Q1, Q3). Spearman correlation analysis and Chi-square test was used to examine the association between the main outcome variable (patients′ optimistic attitudes) and demographic and clinical characteristics. Interaction was examined by hierarchical linear regression analysis combined with simple slope tests. Results:Cancer fatalism was negatively associated with patients′ optimistic attitudes ( r=-0.35, P<0.01). Optimistic attitude of patients was significantly and negatively correlated with the influence of family members′ opinions on medical decision-making ( r=-0.25, P<0.05). There were significant positive correlations between the influence of patients′ and family members′ opinions ( r=0.50, P<0.01), family members′ and physicians′ opinions ( r=0.67, P<0.01), and physicians′ and patients′ opinions ( r=0.38, P<0.01) in medical decision making. Hierarchical linear regression analysis showed a negative association between cancer fatalism and optimism ( β=-0.32, P=0.01). This association was further moderated by the involvement of family members′ opinions ( β=-0.56, P<0.01) and the involvement of physicians′ opinions ( β=-0.36, P=0.04) in medical decision-making. Simple slope tests revealed that the negative impact of fatalistic attitudes on patients′ optimism attitudes may be potentiated when family members′ opinions have high influence on medical decision-making, while the negative impact may be buffered to some extent when physicians′ opinions have high influence on medical decision-making. Conclusions:Cancer fatalism had a negative effect on patients′ optimism. The high influence of physicians in treatment decision-making buffered the negative effect of cancer fatalism on optimism; the high influence of family members in treatment decision-making potentiated the negative effect of cancer fatalism on optimism. In the process of doctor-patient communication and shared decision-making, for patients with strong fatalistic attitudes, consideration should be given to appropriately increasing direct informational communication between physicians and patients and reducing excessive family intervention in medical decision-making, so as to enhance patients′ autonomy for treatment, promote optimism, and reduce the negative effects of cancer fatalism.
RESUMEN
Objective:To investigate the influencing of preoperative biliary drainage on surgery-related complications after pancreaticoduodenectomy.Methods:The retrospective case-control study was conducted. The clinical data of 267 patients with periampullary space-occupying lesion who were admitted to Beijing Friendship Hospital of Capital Medical University from January 2016 to July 2020 were collected. There were 166 males and 101 females, aged 61 (range, 54?84)years. Observation indicators: (1) comparison of preoperative situations in patients with and without preoperative biliary drainage; (2) comparison of intraoperative and postoperative situations in patients with and without preoperative biliary drainage; (3) methods and efficacy of preoperative biliary drainage; (4) factors influencing surgery-related complications after pancreaticoduodenec-tomy. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(rang) or M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was conducted using the corresponding statistical methods based on data type. Multivariate analysis was conducted using the Logistic stepwise regression model. Results:(1) Comparison of preoperative situations in patients with and without preoperative biliary drainage. Of the 267 patients, there were 104 cases with preoperative biliary drainage and 163 cases without preoperative biliary drainage. Cases with malignant tumor, cases with borderline tumor, cases with chronic pancreatitis were 89, 13, 2 in patients with preoperative biliary drainage, versus 111, 41, 11 in patients without preoperative biliary drainage, showing significant differences in pathology type between them ( χ2=10.652, P<0.05). (2) Comparison of intraoperative and postoperative situations in patients with and without preoperative biliary drainage. There was no significant difference in operation time, volume of intra-operative blood loss, postoperative complications, grade B pancreatic fistula, grade C pancreatic fistula, biliary leakage, abdominal or gastrointestinal bleeding, incidence of abdominal infection, white blood cell count at postoperative day 1, white blood cell count at postoperative day 3, neutrophil-to-lymphocyte ratio at postoperative day 1, neutrophil-to-lymphocyte ratio at postoperative day 3, C-reactive protein-albumin ratio at postoperative day 1, C-reactive protein-albumin ratio at post-operative day 3, duration of hospital stay between the 104 patients with preoperative biliary drainage and the 163 patients without preoperative biliary drainage ( P>0.05). (3) Methods and efficacy of preoperative biliary drainage. Of the 104 patients with preoperative biliary drainage, there were 40 cases receiving endoscopic nasobiliary drainage with drainage time as (12±2)days, there were 38 cases receiving percutaneous transhepatic cholangial drainage with drainage time as (7±1)days, and there were 26 cases receiving endoscopic retrograde biliary drainage with drainage time as (19±2)days. The total bilirubin, direct bilirubin, aspartate transaminase, alanine aminotrans-ferase in 104 patients were (223±18)μmol/L, (134±11)μmol/L, (112±10)U/L, (160±16)U/L before biliary drainage and (144±13)μmol/L, (84±8)μmol/L, (79±8)U/L, (109±12)U/L after biliary drainage, showing significant differences in the above indicators ( t=3.544, 3.608, 2.523, 2.509, P<0.05). (4) Factors influencing surgery-related complications after pancreatocoduodenectomy. Results of multi-variate analysis showed that operation time was an independent factor influencing surgery-related complications after pancreaticoduodenectomy ( odds ratio=1.005, 95% confidence interval as 1.002?1.008, P<0.05). Conclusions:Preoperative biliary drainage does not increase the incidence of complications related to pancreaticoduodenectomy in patients with periampullary space-occupying lesion. Operation time is an independent factor influencing postoperative surgery-related complications.
RESUMEN
Objective:To explore the risk factors associated with liver metastasis in T 1 stage colorectal neoplasms patients and establish a prognostic model. Methods:Clinicopathological data of T 1 stage colorectal neoplasms patients from the Surveillance, Epidemiology, and End Results (SEER) database between January 1, 2004, and December 31, 2019 were included. The differences in clinicopathological characteristics between patients with and without liver metastasis were compared using Chi-square test, Wilcoxon rank-sum test, and multivariate Logistic regression analysis. Survival curves were plotted using Kaplan-Meier method, and the Log-Rank test was used to compare survival differences between the two groups. Univariate and multivariate analysis of prognostic factors were performed using the proportional Cox regression hazards regression model. Patients were randomly divided into training set and validation set at a ratio of 6∶4 using simple random sampling method. A nomogram model was established based on independent prognostic factors based on the results of the multivariate Cox regression analysis. The predictive ability of the model was evaluated using time-dependent receiver operating characteristic (ROC) curves and calibration curves. Results:A total of 28 258 T 1 stage colorectal neoplasms patients were included in the study. The multivariate Logistic regression analysis for liver metastasis occurrence indicated that the neuroendocrine neoplasms, elevated carcinoembryonic antigen (CEA) levels, larger neoplasms size, positive lymph node metastasis, and presence of cancer nodules were statistically significant differences ( P<0.05). For T 1 stage colorectal neoplasms patients with liver metastasis, the results of the multivariate Cox regression analysis showed that age, primary site, ethnicity, chemotherapy, and surgical treatment were independent prognostic factors ( P<0.05). The nomogram constructed based on these five prognostic factors had time-dependent ROC areas under the curve of 0.758, 0.797 and 0.729 for 1-year, 3-year, and 5-year survival rates, respectively, 0.749, 0.857, 0.871 in the validation set. The calibration curves of the nomogram in the training and validation sets were close to the 45-degree diagonal line. Conclusions:Neuroendocrine neoplasms, elevated CEA levels, larger neoplasms size, positive lymph node metastasis, and presence of cancer nodules are independent risk factors for liver metastasis in T 1 stage colorectal neoplasms. Age, primary site, ethnicity, chemotherapy, and surgical treatment are independent prognostic factors. The nomogram constructed based on these clinical characteristics has good discrimination and calibration abilities.
RESUMEN
Objective:To explore the practical application and clinical significance of modified grading system for Gastrointestinal Symptom Rating Scale (GSRS) scores in evaluating long-term postoperative gastrointestinal dysfunction (PGID) in patients after colon cancer surgery.Methods:A retrospective analysis was conducted on the case data of 122 patients who underwent right hemicolectomy for colorectal cancer at Beijing Friendship Hospital, Capital Medical University from September 2021 to September 2022. Among these patients, 69 were males (56.6%), and 53 were females (43.4%). The median age was 66.5 years, and the body mass index was (24.4±3.3) kg/m 2. The main observe indiator was GSRS scores of patients. The measurement data of normal distribution were represented as mean±standard deviation( ± s), and intergroup comparisons were conducted using ANOVA. The measurement data of non-normal distribution were expressed as the median (interquartile distance) [ M( Q1, Q3)], the Kruskal-Wallis H test was employed. Unordered count data comparisons were performed using the χ2 test, while comparisons for ordered count data between groups were conducted using the Kruskal-Wallis H test. GSRS scores were represented using density plots, and the scores were categorized into five symptom groups, presented using radar charts to illustrate the distribution of each symptom group. Results:Among the 122 patients, the most common long-term PGID syndromes was dyspepsia, followed by abdominal pain, diarrhea, and constipation. GSRS score data in the study population exhibited a nearly trimodal trend. Based on the overall data trend, the GSRS scale was refined, with cut-off values of 20 and 30, categorizing patients with right-sided colon cancer into low-risk, moderate-risk, and high-risk groups for quantifying the severity of long-term PGID. In terms of gender distribution, the differences among the three groups was statistically significant ( P=0.031), suggesting that males may be more susceptible to long-term PGID. However, there were no significant differences among the three groups concerning age, tumor location, surgical approach, anastomotic technique, lymph node dissection, pathological staging, adjuvant chemotherapy, and other factors. Conclusions:The modified grading system for GSRS scores aligns with the distribution characteristics of postoperative gastrointestinal function in colorectal cancer patients. It can quantify the risk of long-term PGID, allowing for a graded management approach to improve the postoperative quality of life for patients.
RESUMEN
Objective:To explore whether there are gender differences in clinical and pathological characteristics and prognosis of young patients with rectal cancer (under 50 years old), and to analyze the risk factors affecting the prognosis of young patients with rectal cancer.Methods:The medical records of 85 young rectal cancer patients admitted to Beijing Friendship Hospital Affiliated to Capital Medical University from January 2015 to December 2020 were retrospectively collected. According to gender, they were divided into male group ( n=50) and female group ( n=35). The age was (43.67±5.50) years old, ranging from 26 to 50 years old. Primary outcome measures were sex, disease-free survival, and overall survival. Secondary outcomes were family history, body mass index (BMI), clinical stage, anemia, whether the female patient was menopausal, whether the female patient took oral estrogen, the location of the primary lesion, whether neoadjuvant therapy was performed, pathological stage, whether accompanied with vascular nerve invasion, and whether postoperative adjuvant therapy was performed. R4.0.2 software was used for statistical analysis. The measurement data with normal distribution in the collected data were expressed as mean±standard deviation ( ± s), and the comparison between groups was analyzed by t test. Count data were expressed as constituent ratio, and analyzed using the chi-square test or Fisher′s exact test. The survival curve was drawn by Kaplan-Meier method, and the difference in survival rate was tested by Log-rank test. Factors with statistical significance in univariate analysis were included in COX proportional regression model for multivariate analysis to screen independent risk factors affecting overall survival. Results:Compared with male patients, a higher proportion of young female patients with rectal cancer were diagnosed with anemia before surgery (42.9% vs 22.0%, P=0.040). The 1-year, 3-year and 5-year overall survival rates were 94.3%, 80.0% and 68.6% in young female patients, and 98.0%, 90.0% and 90.0% in young male patients, respectively. The median disease-free surival was 31.6 months for women and 34.4 months for men. Multivariate analysis showed that female( HR=3.799, 95% CI: 1.312-11.002, P=0.014)and BMI( HR=0.846, 95% CI: 0.724-0.989, P=0.036)were independent risk factors affecting the prognosis of young patients with rectal cancer. Conclusions:Young female patients have a worse prognosis than male patients. Female and BMI are independent risk factors for the prognosis of young rectal cancer patients, and gender should be the key research object of observation in young rectal cancer patients.
