ABSTRACT
Objective:To evaluate the safety and feasibility of neoadjuvant chemotherapy (NACT) combined with radical surgery for elderly patients with locally advanced gastric cancer (LAGC).Methods:One hundred and fourty eight patients with LAGC after NACT and gastrectomy between 2012 and 2020 were retrospectively reviewed. They were divided into two groups: (1) <65 years old (111 cases) and (2) ≥65 years old (37 cases) and their clinicopathological and prognostic data were compared.Results:There was no significant difference between the two groups in the incidence of hematological complications such as anemia ( χ2=0.235, P=0.628), leukopenia ( χ2=0.613, P=0.434), neutropenia ( χ2=0.011, P=0.918) and thrombocytopenia ( χ2=0.253, P=0.615) and non-hematological complications such as nausea ( χ2=0.092, P=0.762), vomiting ( χ2=0.166, P=0.683), diarrhea ( χ2=0.015, P=0.902) and mucositis ( χ2=0.199, P=0.766) due to NACT. There were no statistical differences between the older patients and the younger in operation duration ( t=0.270, P=0.604), intraoperative bleeding ( t=1.140, P=0.250) and R 0 resection rate ( χ2=0.105, P=0.750). The incidence of postoperative complications was 25.2% and 37.8% in the younger patients and the olders ( χ2=2.172, P=0.141). Pleural effusion ( χ2=7.007, P=0.008) and pulmonary infection ( χ2=10.204, P=0.001) was significantly higher in the older patients than in the youngers. The 3-year progression-free survival rate ( t=0.494, P=0.482) and 3-year overall survival rate ( t=0.013, P=0.908) were comparable between the two groups. Conclusions:NACT combined with radical surgery is safe and effective in elderly patients with LAGC, except for higher perioperative pulmonary-related complications.
ABSTRACT
Objective:To investigate the clinicopathological features and prognosis of patients with gastric gastrointestinal stromal tumor (GIST) combined with digestive tract cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 1 163 patients with gastric GIST who were admitted to the Union Hospital admitted to Tongji Medical College of Huazhong University of Science and Technology from January 2002 to December 2021 were collected. There were 606 males and 557 females, aged 59(range,20?94)years. Of the 1 163 patients, 129 cases with gastric GIST combined with other digestive tract cancer were divided into the combined group, and 1 034 cases with only gastric GIST were divided into the non-combined group. Observation indicators: (1) clinicopathological features of patients; (2) surgical situations and postoperative complications; (3) follow-up and survival of patients; (4) analysis of prognosis associated affecting factors. Follow-up was conducted using outpatient examination, telephone and online interview to detect survival of patients up to January 2022. The overall survival time was defined as the time from surgery to the last tine of follow-up or the outcome events, such as death of patient, loss of follow-up, etc. Measurement data with normal distribution were represented as Mean± SD, and measure-ment data with skewed distribution were represented as M(range). Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Com-parison of ordinal data was conducted using the non-parameter Mann-Whitney U test. Kaplan-Meier method was used to draw survival curves and calculate survival rates, and Log-Rank test was used to conduct survival analysis. The COX proportional hazard model was used for univariate and multivariate analyses. Results:(1) Clinicopathological features of patients. Of the 129 patients in the combined group, there were 81 cases combined with gastric cancer, 39 cases combined with esophageal cancer, 8 cases combined with colon cancer and 1 case combined with rectal cancer. Gender (male, female), cases with age ≤60 years or>60 years, cases without or with clinical symp-toms before surgery, cases with tumor diameter of gastric GIST as<2 cm, 2?5 cm, 5?10 cm,>10 cm, cases with mitotic index as <5/50× high power field, 5?10/50× high power field, >10/50× high power field, cases with cell proliferation index of Ki-67 as ≤5% or >5%, cases classified as extremely low risk, low risk, medium risk and high risk of the modified national institutes of health (NIH) risk classification, cases with or without tumor necrosis of the gastric GIST, cases without or with adjuvant imatinib therapy, cases with the expression of DOG-1 detected by immunohistochemical staining as positive or negative, cases with the expression of CD34 as positive or negative were 92, 37, 30, 99, 9, 120, 114, 10, 3, 2, 126, 1, 2, 122, 2, 112, 8, 5, 4, 129, 0, 121, 8, 118, 3, 117, 12 in the combined group, versus 514, 520, 585, 449, 194, 840, 383, 360,201, 90, 799, 155, 80, 851, 143, 337, 308, 192, 197, 960, 74, 769, 265, 850, 80, 990, 44 in the non-combined group, showing significant differences in the above indicators between the two groups ( χ2=21.46, 51.11, 11.06, Z=?10.27, ?5.34, χ2=15.94, Z=?10.61, χ2=9.86, 24.10, 5.52, 6.37, P<0.05). Of the 1 163 patients, there were 12 cases of the combined group suspected diagnosed as gastric GIST before surgery and 1 case of the combined group dia-gnosed as gastric GIST by gastroscopy and pathological examination before surgery. The rest of 1 150 patients were diagnosed as gastric GIST by intraoperative exploration or postoperative pathological examination. (2) Surgical situations and postoperative complications. Of the 129 patients in the combined group, 72 cases underwent open surgery and 57 cases underwent laparoscopic or thoracoscopic surgery including 3 cases converted to open surgery. Of the 1 034 patients in the non-combined group,207 cases underwent endoscopic surgery, 371 cases underwent open surgery, and 456 cases underwent laparoscopic or thoracoscopic surgery including 8 cases converted to open surgery. Incidence of postoperative complications was 10.078%(13/129) in the combined group, versus 2.321%(24/1 034) in the non-combined group, showing a significant difference between the two groups ( χ2=22.40, P<0.05). (3) Follow-up and survival of patients. Of the 1 163 patients, 1 046 cases were followed up for 44(range, 1?220)months, with the postoperative 5-year overall survival rate as 87.2%. The postoperative 5-year overall survival rate was 51.2% in the combined group, versus 91.4% in the non-combined group, showing a significant difference between the two groups ( χ2=169.07, P<0.05). (4) Analysis of prognosis associated affecting factors. Results of univariate analysis showed that gender, age, tumor diameter of gastric GIST as 2?5 cm, 5?10 cm and >10 cm, combined with other digestive tract cancer, mitotic index as >10/50× high power field and tumor necrosis of the gastric GIST were related factors affecting the postoperative 5-year overall survival rate of patients with gastric GIST ( hazard ratio=2.16, 2.27, 0.46, 0.57, 1.75, 7.58, 2.70, 1.80, 95% confidence intervals as 1.52?3.07, 1.60?3.22, 0.29?0.71, 0.34?0.94, 1.11?2.77, 5.29?10.85, 1.67?4.38, 1.08?2.98, P<0.05). Results of multivariate analysis showed that gender, age, tumor diameter of gastric GIST, combined with other digestive tract cancer and mitotic index were independent factors affecting the post-operative 5-year overall survival rate of patients with gastric GIST ( hazard ratio=1.91, 1.82, 2.10, 7.11, 2.75, 95% confidence intervals as 1.33?2.75, 1.27?2.62, 1.14?3.87, 4.58?11.04, 1.50?5.03, P<0.05). Conclusions:The tumor diameter of gastric GIST is short in patients combined with other digestive tract cancer, and the risk grade of modified NIH risk classification is lower. Gender, age, tumor diameter of gastric GIST, combined with other digestive tract cancer and mitotic index are independent factors affecting the postoperative 5-year overall survival rate of patients with gastric GIST.
ABSTRACT
Leucine rich glioma inactivated 1 (LGI1) is a protein which is identified as the target involving in autoimmune encephalitis. Seizures and cognitive declines are two main symptoms of LGI1-antibody encephalitis. However, autonomic dysfunction symptoms are not prominent as seizures and cognitive defection and are easily overlooked by physicians. We reported a case with LGI1-antibody encephalitis whose onset symptoms were autonomic dysfunction including sweating, orthostatic hypotension. The features of this case was described in detail and the related literatures were reviewed in order to enhance the knowledge of the disease.
ABSTRACT
Objective@#To investigate the morbidity and treatment of early postoperative complications after laparoscopic D2 radical gastrectomy for gastric cancer, and to explore the risk factors.@*Methods@#A case-control study was performed to retrospectively collect clinicopathological data of 764 patients undergoing laparoscopic D2 radical gastrectomy for gastric cancer at our department between January 2015 and December 2017. Patient inclusion criteria: (1) gastric cancer diagnosed by preoperative electronic gastroscopy and biopsy, and confirmed by postoperative pathology; (2) without invasion into adjacent organs by preoperative evaluation of tumors; (3) tumors without definite liver and distant metastasis; (4) R0 resection of gastric cancer and standard D2 lymph node dissection; (5) patients with informed consent. Exclusion criteria: (1) unperformed laparoscopic D2 radical resection; (2) other types of gastric tumor confirmed by pathology; (3) cases with incomplete clinical data. Complication occurring within two weeks after laparoscopic D2 gastrectomy was defined as early postoperative complication. Patients were divided into two groups: non-complication group (693 cases) and complication group (71 cases) according to the occurrence of complications after operation. The clinicopathological data of two groups were analyzed and compared with t test and χ2 test, and the factors of P < 0.2 were included in the multivariate logistic regression model to analyze the risk factors of postoperative complications.@*Results@#Of 764 patients, 71 (9.3%) developed early postoperative complications, with median onset time of 3 (1 to 11) days. Surgical complications accounted for 7.9% (60/764), including 13 cases (1.7%) of abdominal hemorrhage, 12 cases (1.6%) of anastomotic leakage, 10 cases (1.3%) of incision infection, 8 cases (1.0%) of anastomotic bleeding, 7 cases (0.9%) of gastric stump weakness, 4 cases (0.5%) of abdominal infection, 4 cases (0.5%) of duodenal stump leakage and 2 cases (0.3%) of small intestinal obstruction. Non-surgical complications accounted for 1.4% (11/764), including 6 cases (0.8%) of pulmonary infection and 5 cases (0.7%) of cardiovascular disease. Two cases (0.3%) died of sepsis caused by severe abdominal infection; 9 cases (1.2%) recovered after receiving the second operation, among whom 5 cases were abdominal hemorrhage, 2 cases were anastomotic leakage and 2 cases were duodenal stump leakage; the remaining patients were healed with conservative treatment. Compared with patients without complications, patients with complications had higher proportions of BMI ≥24 kg/m2 [42.3% (30/71) vs. 24.2%(168/693), χ2=10.881, P=0.001], comorbity [64.8% (46/71) vs. 33.5% (232/693), χ2=27.277, P<0.001], combined organ resection [70.4% (50/71) vs. 20.5% (142/693), χ2=85.338, P<0.001], and pTNM stage of III [70.4% (50/71) vs. 40.1% (278/693), χ2=24.196, P<0.001], meanwhile had longer time to postoperative flatus [(4.2±2.1) days vs. (2.9±1.2) days, t=4.621, P=0.023], longer hospital stay [(34.6±12.6) days vs. (14.2±6.2) days, t=9.862, P<0.001] and higher hospitalization cost [(126.8±64.5) thousand yuan vs. (85.2±35.8) thousand yuan, t=11.235, P<0.001]. Multivariate analysis showed that BMI ≥24 kg/m2 (OR=3.762, 95% CI: 1.960-8.783, P=0.035), accompanying disease (OR=8.620, 95% CI: 1.862-29.752, P<0.001), combined organ resection (OR=6.210, 95% CI: 1.357-21.568, P=0.026), and pTNM stage (OR=4.752, 95% CI: 1.214-12.658, P<0.001) were the independent risk factors of postoperative complications.@*Conclusions@#Laparoscopic D2 radical gastrectomy is a safe and effective approach for gastric cancer. Most early postoperative complications can obtain satisfactory efficacy after conservative treatment. Perioperative management should be strengthened for those patients with high BMI, accompanying diseases, combined organ resection, and advanced pTNM stage.
ABSTRACT
Objective@#To explore the features of imatinib mesylate (IM) plasma concentration during adjuvant therapy and clinical factors associated with IM plasma concentration in patients with high risk gastrointestinal stromal tumors (GIST), and to determine whether IM plasma concentration <1100 μg/L influences the efficacy of adjuvant therapy.@*Methods@#A retrospective case control study method was used. Case inclusion criteria: (1) complete resection of lesion and GIST confirmed by pathology; (2) high risk classified according to modified National Institutes of Health classification system (2008); (3) administration of IM 400 mg/d for at least 1 month; (4) not taking the medication likely affecting IM pharmacokinetic, such as rifampicin, dilantin, and carbamazepine, within 1 month before blood collection. Data of GIST patients who visited GIST Disease - Oriented Outpatient, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology between January 2015 to December 2018 were retrospectively analyzed. After taking IM for 22-26 hours, 5 ml of peripheral venous blood was collected into EDTA anticoagulant tube. IM plasma concentration was detected by using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Patients were divided into <1100 μg/L group and ≥1100 μg/L group according to plasma concentration. Linear regression was used to analyze the relevance between clinical features and IM plasma concentration. Parameters with normal distribution were analyzed by Pearson correlation coefficient, and parameters with non-normal distribution were analyzed by Spearman correlation. Kaplan-Meier survival curves and COX regression model were used for survival analysis.@*Results@#Among the 85 patients enrolled in the study, 49 patients (57.6%) were male and 36 (42.4%) were female, with mean age of (51.9±11.0) years. The body mass index was (22.5±2.9) kg/m2 and body surface area was (1.6±0.2) m2. Thirty patients received gene test, including 23 patients with c-Kit exon 11 mutation, 4 with c-Kit exon 9 mutation, 1 with c-Kit exon 11 and 17 mutation and 2 without c-Kit or PDGFRA gene mutation. The mean IM plasma concentration was (1391.4±631.3) μg/L, and there were 32 patients with plasma concentration <1100 μg/L and 53 patients with plasma concentration ≥1100 μg/L. There were no statistically significant differences between the two groups in gender, age, body mass index, body surface area, hematological examination (white blood cells, albumin, alanine aminotransferase, aspartate aminotransferase and serum creatinine), tumor location, tumor size, mitotic counts, duration of adjuvant therapy and methods of operation (all P>0.05). Positive correlation between IM plasma concentration and serum creatinine was observed in linear regression analysis (r=0.297, P=0.007), but there were no correlations between IM plasma concentration and age (r=0.044, P=0.686), body mass index (r=0.066, P=0.547), body surface area (r=-0.010, P=0.924), white blood cells (r=-0.080, P=0.478), albumin (r=-0.065, P=0.563), alanine aminotransferase (r=0.114, P=0.308), aspartate aminotransferase (r=0.170, P=0.127) and duration of adjuvant therapy (ρ=0.060, P=0.586). There was no statistically significant difference in IM plasma concentration between patients with different genders (t=0.336, P=0.738) and patients with different surgical methods (F=0.888, P=0.451). Up to March 1, 2019. the median follow-up time was 30 (range 4-49) months. Tumor recurrence was detected in two patients with plasma concentration <1100 μg/L and two with plasma concentration ≥1100 μg/L. One recurrent patient with plasma concentration <1100 μg/L was detected to harbor c-Kit exon 11 and exon 17 mutations, and the other did not receive gene detection. Two recurrent patients with plasma concentration ≥1100 μg/L were both detected to harbor c-Kit exon 9 mutation. The 3-year relapse-free survival rate was 96.4% in the cohort, 96.2% in patients with plasma concentration <1100 μg/L, and 96.6% in patients with plasma concentration ≥1100 μg/L. No significant difference in relapse-free survival was observed between the two groups (P=0.204). Univariate Cox analysis showed that IM plasma concentration <1100 μg/L was not a risk factor for patients with high risk GIST (HR=0.238, 95% CI: 0.022-2.637, P=0.242).@*Conclusions@#IM plasma concentration of adjuvant therapy in patients with high risk GIST varies with individual. Patients with higher level of serum creatinine are more likely to have a higher plasma concentration. A blood drug concentration standard of less than 1100 μg/L for advanced GIST patients may not influence the prognosis of patients with high risk GIST.
ABSTRACT
Objective To explore the clinical prognosis and efficacy of adjuvant therapy with imatinib of postoperative patients with gastric intermediate-risk gastrointestinal stromal tumor (GIST).Methods The clinicopathological data and follow-up data of 93 gastric intermediate-risk GIST cases from Jan 2005 to Dec 2016 at Union Hospital were analyzed retrospectively.Univariate and multivariate analysis were performed to assess the prognostic factors.Results There were 93 patients undergoing complete GIST resection with 42(45％) cases receiving post-op imatinib 400 mg/d for targeted therapy.The median target therapy period was 12 (6-72) months.86％ (80 cases) patients were followed up for 46 (6-120) months.The 1-,3-,5-year recurrence-free survival rate (RFS) of the whole group were 100％,91.5％,88.5％ respectively.Multivariate analysis revealed that mitotic count (P =0.040,RR =6.078,95％ CI:0.541-68.274) and neutrophil-lymphocyte ratio (NLR) (P =0.036,RR =6.102,95％ CI:0.782-47.632) were prognostic risk factors of RFS.For those mitotic count ＞ 2/50 HPF and NLR ＞ 2.3,adjuvant therapy with imatinib significantly increases RFS.Conclusion Mitotic count and NLR were independent risk factors of RFS in gastric intermediate-risk GIST.For those with mitotic count ＞ 2/50 HPF and NLR ＞ 2.3,postoperative adjuvant therapy with imatinib helps improve the prognosis.
ABSTRACT
Objective To investigate the clinical efficacy and safety of domestic imatinib in the treatment of gastrointestinal stromal tumor (GIST). Methods Clinicopathological and follow-up data of GIST patients who received domestic imatinib treatment from January 2014 to December 2017 in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were analyzed retrospectively. The treatment efficacy and adverse reactions were analyzed. Results A total of 35 patients included 20 males and 15 females with a median age of 53 years old (28-79 years old). Among all the patients, 25 with primary GIST underwent complete resection, in which 20 cases were classified as high risk and 5 as moderate risk according to the risk stratification. Of the remaining 10 recurrent/metastatic or unresectable GIST patients, 6 cases had metastasis in liver, 2 cases had metastasis in peritoneum, 1 case had extensive abdominal and pelvic metastasis, and the other 1 case was initially unresectable. The follow-up data of all the 35 patients were available, with a median follow-up time of 25 months (4-49 months). Twenty-five primary patients with complete resection received adjuvant therapy with a median time of 14 months (4-44 months). The median time of follow-up was 25 months (4-49 months), and none of the primary patients was detected with recurrence or metastasis of GIST. Meanwhile, of the 10 patients with recurrent/metastatic or unresectableGIST, the median time of medicine-taking was 24 months (3-49 months). Seven of 10 patients received imatinib monotherapy, including 5 cases of partial remission and 2 cases of stable disease. The other 3 patients with localized progression received complete resection along with imatinib therapy. All the 10 patients achieved durable clinical benefit. Twenty-seven patients (77.1％) experienced adverse events, and only 1 case (2.9 ％) had grade 3 adverse events. Conclusion Domestic imatinib is effective and safe for patients who received adjuvant therapy after complete resection of primary GIST as well as those with recurrent/metastatic or unresectable GIST, but it remains to be further confirmed by large samples of prospective studies.
ABSTRACT
Objective To investigate the clinical characteristics,treatment strategies and curative effect of recurrence and metastasis of primary gastrointestinal stromal tumor (GIST) after complete resection along with adjuvant therapy with imatinib,and to analyze the risk factors of recurrence and metastasis after adjuvant therapy.Methods The demographic data,clinicopathological characteristics and follow-up data of 80 primary GIST patients who received adjuvant therapy with imatinib for at least 1-year duration and had already stopped taking imatinib from January 2005 to December 2017 in Union Hospital,Tongji Medical College,Huazhong University of Science and Technology were analyzed retrospectively.The survival analysis was performed using Kaplan-Meier approach.Univariate analysis was conducted using log-rank test.Multivariate analysis was produced by Cox regression model.Results Of the enrolled 80 patients,recurrence and metastasis were detected in 17 cases after completion of postoperative adjuvant therapy with imatinib,with a median recurrence time of 12 months.All the 17 patients showed no specific clinical manifestations.Liver metastasis,peritoneum metastasis and local recurrence were found in 9,5 and 3 cases,respectively.In the 17 patients with recurrence and metastasis,9 patients received imatinib monotherapy.Among the 9 patients,6 achieved partial responses,while 3 demonstrated stable disease,and secondary drug resistance was found in 7 patients during the follow-up period,with a median progression-free survival of 35 months (95％ CI:15-55 months) and median overall survival of 49 months (95％ CI:30-68 months).A total of 7 patients with recurrence and metastasis were treated with imatinib after operation and achieved satisfying tumor control,and secondary drug resistance was found in 4 patients during the follow-up period,with a median progression-free survival of 31 months (95％ CI:6-56 months) and fell short of median overall survival.The remaining 1 patient gave up treatment.Univariate analysis showed that tumor location (x2 =4.120,P =0.042),preoperative neutrophil-to-lymphocyte ratio (NLR) (x2 =7.513,P =0.006) and preoperative platelet-to-lymphocyte ratio (PLR) (x2 =6.575,P =0.010) were associated with recurrence and metastasis of GIST patients after completion of adjuvant therapy.Multivariate analysis revealed that tumor location (HR =3.787,95％ CI:1.126-12.732,x2 =4.631,P =0.031) was an independent prognostic factor for those patients.Conclusion GIST patients who are identified recurrence and metastasis after completion of adjuvant imatinib treatment show no specific clinical manifestations after stopping andjuvant therapy with imatinib.Compared with gastric GIST,non-gastric origin GIST has a higher risk of recurrence.Imatinib monotherapy and surgery combined with imatinib therapy are both effective in treating this subgroup of patients.
ABSTRACT
One hundred patients with Parkinson's disease (PD) aged 60 and above treated with levodopa were enrolled in this cross section study.The general conditions,medication,unified Parkinson's disease rating scale (UPDRS) scores and the incidence of levodopa-induced dyskinesia (LID) were documented.The incidence rate of LID in this group of PD patients was 37.0％ (37/100).The incidence was significantly higher in patients with levodopa treatment ≥ 4 years than that in patients with levodopa treatment ＜ 4 years (55％ vs.26％,x2 =8.770,P =0.003).The incidence rate ofpeak dosage dyskinesia in tremor-dominant PD patients was lower than that in rigidity-dominant PD patients(x2 =4.399,P =0.036).The incidence rate of LID was correlated with the duration of levodopa therapy.Amantadine may reduce the incidence of off dystonia.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the clinical characteristics, diagnosis and treatment as well as prognostic factors of the giant gastrointestinal stromal tumor (GIST).</p><p><b>METHODS</b>Clinical data of 235 patients with high risk GIST treated in the Union Hospital, Tongi Medical College, Huazhong University of Science and Technology between January 2005 and July 2015 were retrospectively analyzed. Patients were divided into giant GIST group (diameter equal to or larger than 10 cm, 119 cases) and high risk group (diameter less than 10 cm, 116 cases) according to tumor size. Clinical characteristics and prognosis of two groups were compared and the clinical features of giant GIST were summarized. Multivariate analysis was performed to evaluate the prognostic factors of giant GIST with Cox regression model.</p><p><b>RESULTS</b>Of the 119 patients with giant GIST, which accounted for 50.6%(119/235) of all the high risk patients, there were 63 male and 56 female patients with a median age of 53(20-82) years. Primary giant GIST of 43(36.1%) located in the stomach, of 39(32.8%) in the small intestine, 5(4.2%) in the colon and rectum, and of 32 (26.9%) outside the gastrointestinal tract (mesentery, retroperitoneum, abdominal cavity, etc) and pelvic. Compared to high risk group, age of onset was younger [ratio of ≤50 years, 44.5%(53/119) vs. 31.9%(37/116), P = 0.046] and incidence of outside the gastrointestinal tract was significantly higher [26.9%(32/119) vs. 9.5%(11/116), P=0.000] in giant GIST group. All the giant GIST patients underwent surgical resection, including 115 cases(96.6%) of R0 resection, 3 cases(2.5%) of R1 resection and 1 case(0.9%) of R2 resection, besides, 32 cases(26.9%) underwent expanded resection (namely, underwent lymphadenectomy or combined organ resection simultaneously). Thirty-nine giant GIST cases(32.8%)accepted imatinib 400 mg/d for targeted therapy after operations, which was not significantly different with high risk group (46 cases, 39.6%, P=0.232). Relapse and metastasis occurred in 8 cases in giant GIST group. The 1-, 3-, 5-year overall survival rates of giant GIST group were 94.5%, 89.3%, 79.4% respectively and of high risk group were 99.1%, 92.9%, 85.1% respectively, and no significant difference was found (P=0.788). The 1-, 3-, 5-year recurrence-free survival rates of giant GIST group were 93.6%, 85.1%, 72.8% respectively and of high risk group were 99.1%, 91.7%, 84.2% respectively, and no significant difference was found as well (P=0.932). Multivariate analysis revealed that gender (P=0.047, RR=0.383, 95%CI:0.149-0.987), mitotic count (P=0.001, RR=0.216, 95%CI:0.087-0.538) and targeted therapy(P=0.019, RR=5.719, 95%CI:1.324-24.695) were prognostic risk factors of overall survival (OS), moreover, tumor size (P=0.024, RR=0.368, 95%CI:0.155-0.875) and mitotic count(P=0.007, RR=0.357, 95%CI:0.169-0.755) were prognostic risk factors of RFS.</p><p><b>CONCLUSIONS</b>Giant GIST is not unusual in GIST and more likely occurs outside gastrointestinal tract. Complete surgical excision combined with targeted therapy can improve the prognosis significantly. The prognosis of giant GIST and common high risk GIST is similar. Mitotic count is the most important prognostic factor.</p>

To explore the safety of ropinirole in the treatment of Parkinson′s disease( PD).A total of 221 PD patients participated in a multi-center,12-week randomized,bromocriptine-controlled,double-blind, double-dummy and parallel-group trial.The safety was assessed on the basis of adverse reactions , blood pressure,pulse,laboratory parameters and electrocardiography recordings.The incidence of adverse reaction was 34.9%in ropinirole group and 34.8% in bromocriptine group.And the frequency of adverse reactions had no inter-group statistical significance (χ2 =0.000,P=0.995).Ropinirole has an excellent profile of safety in the treatment of Chinese PD patients.
ABSTRACT
BACKGROUND: Essential tremor is a kind of dyskinesia disease with a tendency to heredity. β-adnephrin receptor blocker is mainly used for treatment, but the dosage was great, patients could not persist in treatment. Hydrochloric-acid arotinolol, which characterizes by little side effect, is a β-receptor blocking agent combined with blocking effect of α receptor, and is an ideal drug to treat essential tremor in Japan.OBJECTIVE: To observe the reliability and curative effect of hydrochloric-acid arotinolol on essential tremor among Chinese people.DESIGN: Case analysis.SETTING: Neurological Departments of Beijing Hospital of Ministry of Public Health and General Hospital of Beijing Military Area Command of Chinese PLA.PARTICIPANTS: Totally 30 patients with essential tremor, 19 males and 11 females, aged from 21 to 74 years, with course of 1-40 years, average of (15.8±12.6) years, were selected from Neurological Departments of Beijing Hospital of Ministry of Public Health and General Hospital of Beijing Military Area Command of Chinese PLA from April 1999 to December 2000.METHODS: Tremor degree of upper limb, caput and lower limb, degree of dysfunction of hand, tremor degree of hand during writing and circling, and chief complaint of pain caused by tremor were scored before medication and 2, 4 and 6 weeks after medication. Scores were determined as 1 point, 2 points and 3 points according to mild, moderate and severe degree respectively. Evaluated criteria: ① Obviously effective: Differences were more than 7 points before and after treatment. ② Effective: Differences were 6.5-3 points before and after treatment. ③ A little effective: Differences were 3-1.5 points before and after treatment. ④ No changes: Differences were from 1 to -1 points before and after treatment. ⑤ Worse: Differences were less than -1.5 points before and after treatment. Meanwhile, blood pressure and heart rate of patients and side effect of drug were observed.MAIN OUTCOME MEASURES: ① Results of effective evaluation; ②Blood pressure and heart rate before and after treatment; ③ Adverse events and side effect.RESULTS: Totally 30 patients entered the final analysis. ① Among 30 patients with essential tremor, 6 had obvious effect, 11 had effect, 5 had a little effect, 7 had no effect, and 1 was worse. ② Average of blood pressure before treatment was (138.5±14.6)/(84.2±6.4) mm Hg (1 mm Hg=0.133 kPa), and was (130±10)/(79.7±6.3) mm Hg after 1 course. Average heart rate was (77.5±6.4) times/minute before treatment and (75±6.4) times/minute after treatment. The difference was not significant. ③ Among 30 patients, 4 had side effect at various degrees which was accounted for 13.4%; 1 had distress after medication, 1 had agrypnia, 2 had fullness in head and dizziness, and 1 gave up the treatment because of deteriorated tremor.CONCLUSION: Hydrochloric-acid arotinolol can improve tremor symptom of patients obviously and is an effective drug to treat essential tremor with convenient and safe medication.
ABSTRACT
@# Objective To assess the clinical efficacy and safety of amantadine monotherapy and concomitant amantadine with salvia miltiorrhiza compound or selegiline of the treatment of Parkinson's disease.Methods The clinical trial was performed in the multicenter, open label study. Amantadine group: 35 cases, amantadine plus salvia miltiorrhiza compound group: 34 cases and amantadine plus selegiline group: 29 cases. The clinical efficacy had been assessed with modified Webster scale (WR) and motor dysfunction rating scale for Parkinson's disease (MDRSPD) with interval of two months for one year. The safety data included blood glucose, hepatic and renal function tests, blood and urine routine tests.Results The clinical improved rates were 42.9% (WR) and 37.1% (MDRSPD) in amantadine group, respectively. The clinical score was improved in 34.2% (WR) and 26.5% (MDRSPD) in amantadine plus salvia miltiorrhiza compound group, respectively. The clinical improvement was 51.1% (WR)and 48.3% (MDRSPD) in amantadine plus selegiline group, respectively. There were no significant differences among these three groups (t-test,P>0.05). The clinical marked efficacy rates in assessment of MDRSPD were 2.8% in amantadine group, 11.8% in amantadine plus salvia miltiorrhiza compound group and 27.6% in amantadine plus selegiline group, respectively. There was significant difference between amantadine group and amantadine plus selegiline group, but no significant difference between amantadine group and amantadine plus salvia miltiorrhiza compound group. The adverse event rates were 27.8% in amantadine group, 8.8% in amantadine plus salvia miltiorrhiza compound group and 31.0% in amantadine plus selegiline group, respectively. All these events were mild, of short duration and resolved without treatment. Conclusion There was some efficacy rate in all three groups. Comparing with amantadine group, there was higher marked efficacy rate in amantadine plus selegiline group.
ABSTRACT
Objective The clinical efficacy and safety of L dopa monotherapy and concomitant L dopa therapy with dopamine agonists (bromocriptine or pergolide) of the treatment of Parkinson's disease Methods The clinical trial was performed in the multicentre,open label study L dopa group: 47 cases,L dopa plus bromocriptine group: 43 cases and L dopa plus pergolide group: 48 cases The clinical efficacy was assessed with modified Webster's scale and motor dysfunction rating scale for Parkinson's disease ( MDRSPD ),and safety data included blood hepatic and renal function tests,blood and urine routine tests,arterial blood pressure,heart rate measurements and electrocardiogram were also analyzed at the beginning and end of study The average daily dose of L dopa in levedopa group was (523 3?235 9) mg,The average daily dose of L dopa and bromocriptine were (526 7?241 3) mg and (7 3?1 5) mg in L dopa plus bromocriptine group,respectively The average daily dose of L dopa and pergolide were (558 3?192 9)mg and (0 235?0 045) mg in L dopa plus pergolide group separately Result The clinical improvement was about 74 5%both in assessment of modified Webster's scale and MDRSPD in L dopa group The clinical score was improved in 69 8% (Webster's scale) and 79 1% (MDRSPD) in L dopa plus bromocriptine group,respectively The clinical improved rates were 77 9%( Webster's scale ) and 81 3%( MDRSPD ) in L dopa plus bergolide group The incidence rates of side effects were 27 7%in L dopa group,39 5%in L dopa plus bromocriptine and 18 8%in L dopa plus pergolide groups Conclusion There was an efficacy in treatment of Parkinson's disease in either L dopa monotherapy or combination with bromocriptine or pergolide The treatment of L dopa alone was more effective in the early stage of Parkinson's disease and concomitant L dopa therapy with dopamine agonists were more effective in the advanced stage of Parkinson's disease,pergolide was not only more effective,safe and tolerable,but also fewer adverse events than Bromocriptine was in this short term trial
