RESUMEN
Objective:To investigate the clinical characteristics and prognosis of duodenal neuroendocrine neoplasms.Methods:The clinical data of 35 patients with duodenal neuroendocrine neoplasms admitted to Union Hospital, Tongji Medical College, Huazhong University of Science & Technology from Jan 2012 to Dec 2021 were retrospectively analyzed. The differences of clinical characteristics between periampullary and non-periampullary duodenal neuroendocrine neoplasms were analyzed. Kaplan-Meier curve was used for survival analysis, and the clinical factors affecting the prognosis were analyzed.Results:Of the 35 patients, 30 underwent tumor resection, 7 (23%) developed different degree of complications after operation and were improved and discharged after intervention. A total of 5 patients died during the follow-up period. Only 1 of 30 patients who underwent tumor resection died 30 months after operation due to disease progression, and the others had no recurrence or metastasis. Univariate analysis showed that tumor size, tumor grade, and tumor location were associated with the prognosis of patients (all P<0.05), and multivariate analysis showed that patients with tumors located.Away from the ampulla had a significantly better prognosis than those located around the duodenal ampulla ( P<0.01). Conclusions:Patients with duodenal neuroendocrine neoplasms have a good prognosis after complete resection; patients with duodenal neuroendocrine neoplasms located around the ampulla of Vater have a relatively poor prognosis compared with those away from the area of ampulla.
RESUMEN
Objective:To review the incidence and treatment status of perioperative anemia in patients with gastric cancer.Methods:The clinicopathological data of gastric cancer patients who underwent surgery at Department of Gastrointestinal Surgery, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from Jan to Dec 2019 were collected. Univariate analysis and multivariate Logistic regression analysis were used to explore the risk factors of preoperative anemia in gastric cancer.Results:A total of 879 patients were included in this study. The incidence of preoperative anemia in patients with gastric cancer was 35.6%. The incidence of postoperative anemia was 63.5%. The proportion of patients with preoperative anemia receiving treatment was 17.3%, and the proportion of patients with postoperative anemia receiving treatment was 17.4%. Univariate analysis showed that age, nutritional risk screening 2002, T stage, M stage, tumor stage and lymph node metastasis were associated with preoperative anemia (all P<0.05). Multivariate Logistic regression analysis showed that age >60 years , nutritional risk screening 2002 ≥3, T 3-4 stage and M 1 stage were independent risk factors for preoperative anemia in patients with gastric cancer (all P<0.05). Conclusions:The incidence of perioperative anemia in patients with gastric cancer is high. At present, the proportion of patients with perioperative anemia receiving treatment is low. High nutritional risk, advanced age, late tumor T stage and distant metastasis are independent risk factors for preoperative anemia in patients with gastric cancer.
RESUMEN
Objective:To identify the clinical factors associated with pathological complete response (pCR) after neoadjuvant chemoradiotherapy (nCRT) in locally advanced middle and low rectal cancer and establish a scoring system.Methods:In this retrospective analysis the clinical data of patients with locally advanced middle and low rectal cancer treated with nCRT combined with surgery at Union Hospital of Tongji Medical College, Huazhong University of Science and Technology from Jan 2016 to Jan 2020 were studied. Patients were divided into pCR group and non-pCR group. Single factor analysis and Logistic multivariate regression analysis were performed to explore pCR related factors after nCRT, and a pCR prediction scoring system was established.Results:The pCR was achieved in 33 patients (20.8%). Univariate analysis showed that the maximum thickness of the tumor≤25mm before nCRT ( P=0.046), concurrent oxaliplatin-combined intensive chemotherapy ( P=0.013), the NLR≤1.65 before nCRT ( P=0.004) and the serum CEA≤5 ng/ml before nCRT ( P=0.016) were significantly associated with pCR. In multivariate analysis, concurrent oxaliplatin-combined intensive chemotherapy, the NLR before nCRT and serum CEA before nCRT were independent related factors of pCR. The probability of pCR for patients with score of 0, 1, 2, and 3 was 42% (10/24), 30% (19/63), 5% (3/57) and 7% (1/15), respectively. The probability of pCR in patients with score≤1 point was 33% (29/87), and 6% (4/72) for score?1 point ( P?0.001). The area under the curve of the scoring system is 0.729 (95% CI: 0.638-0.820, P?0.001). Conclusions:Concurrent oxaliplatin-combined intensive chemotherapy, NLR≤1.65 before nCRT and serum CEA≤5 ng/ml before nCRT are independent predictors of pCR in locally advanced middle and low rectal cancer and the scoring system constructed in combination with above indicators can effectively predict pCR.
RESUMEN
Objective:To explore the value of Caprini risk assessment scale and serum D-dimer in early prediction of postoperative lower extremities deep vein thrombosis (DVT) in patients with gastrointestinal malignant tumor.Methods:A total of 240 patients with gastrointestinal malignant tumors treated in Union Hospital of Tongji Medical College of Huazhong University of Science and Technology from Jan to Oct 2020 were analyzed retrospectively.Results:Caprini score was 4 in 8 cases, 5-7 in 217 cases, and 8 in 15 cases. Sixty-seven patients developed lower extremity DVT after operation. No patients with Caprini score of 4 had DVT, 57 cases (26.3%) with a score of 5-7 had DVT; 10 cases whose score were ≥8 points (66.7%) developed DVT. There was a higher incidence of lower extremity DVT in patients ≥8 points than those of 5-7 points after surgery ( P<0.01). The postoperative Caprini score of the DVT group was higher than that of the non-DVT group (6.37±1.01 vs. 5.80±0.94, t=4.108, P<0.001). D-dimer on the first day after operation in DVT group (4.08±2.27 vs. 2.01±1.04, t=7.715, P<0.001) and the level of serum D-dimer (2.93±1.81 vs. 2.30±1.21, t=2.631, P<0.001) on day 3 was higher than that in the non-DVT group. According to the ROC curve, the best cut-off value for serum D-dimer to predict lower extremity DVT on the first postoperative day was 2.84 mg/L, the sensitivity was 70.1%, the specificity was 87.3%, and the area under the curve (AUC) was 0.815. The best cut-off value of D-dimer for predicting lower limb DVT on day 3 after surgery was 1.67 mg/L, sensitivity was 85.1%, specificity was 34.7%, and AUC was 0.611. Conclusions:Patients with gastrointestinal malignant tumors have a high incidence of postoperative lower extremity DVT. When the serum D-dimer exceeds 2.84 mg/L on the first postoperative day, the likelihood of postoperative lower extremity DVT is higher.
RESUMEN
Objective:To explore the clinical features, diagnosis, treatment and prognosis of rectal neuroendocrine tumor with lymphatic metastasis.Method:There were 153 case who were diagnosed with RNET, among them, there were 10 patients(6.5%) with lymphatic metastasis in Affiliated Union Hospital, Tongji Medical College, Huazhong University of Science & Technology from January 2012 to December 2020, including 4 males and 6 females, aged from 32 to 71 years old, and the median age was 56.5 years.Results:Of the 10 patients, 3 had tumors < 1 cm in diameter, 4 had 1 to 2 cm, and 3 had > 2 cm. Preoperative CT examination was performed in 10 patients, of which 9 suggested lymphatic metastasis; preoperative MRI examination was performed in 7 patients, of which 6 suggested lymphatic metastasis. All patients were received radical resection, in which Miles operation was performed in 2 cases, Dixon operation in 6 cases, and additional Dixon operation after endoscopic submucosal dissection in 2 cases.All patients were followed up for 51 months (ranged from 14 to 118 months). Nine patients had no recurrence or metastasis, and one patient had abdominal metastasis 40 months after surgery and died after 31 months of comprehensive treatment.Conclusions:Lymphatic metastasis is rare in rectal neuroendocrine tumor. Imaging examination has important reference value for judging the status of lymphatic metastasis. For rectal neuroendocrine tumor with lymphatic metastasis, radical resection is effective.
RESUMEN
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.

The treatment group was intervened by moxa stick moxibustion, while the control group was given oral administration of Domperidone tablets, 7 d as a treatment course, totally for 2 courses. The DGP clinical symptoms evaluation scale, gastric emptying time and biochemical indexes (contents of glycosylated hemoglobin and serum motilin) were compared before and after the treatment, and the clinical efficacies were compared between the two groups.Result After the treatment, the DGP clinical symptoms evaluation scales, gastric emptying time, and biochemical indexes were changed significantly in both groups (P<0.05). The DGP clinical symptoms evaluation scales, gastric emptying time, and biochemical indexes in the treatment group were significantly different from those in the control group after the treatment (P<0.05).Conclusion Moxa stick moxibustion can improve the quality of life of DGP patients due to deficient cold of spleen-stomach, which is possibly related to the improvement of the glycosylated hemoglobin, serum motilin and gastric emptying time.
RESUMEN
Objective To investigate the clinical efficacy of acupuncture plus massotherapy in treating cervicogenic headache. Methods Ninety-seven patients with cervicogenic headache were randomly allocated to a treatment group of 62 cases and a control group of 35 cases. The treatment group received acupuncture plus massotherapy and the control group, massotherapy alone. The VAS score was recorded and plasma nitric oxide (NO) and endothelin (ET) levels were measured in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups. Results The total efficacy rate was 95.2% in the treatment group and 82.9% in the control group; there was a statistically significant difference between the two groups (P<0.05). There were statistically significant pre-/post-treatment differences in the VAS score, neck mobility, and plasma NO and ET levels in the two groups (P<0.05). There were statistically significant post-treatment differences in the VAS score, neck mobility, and plasma NO and ET levels in the treatment and control groups (P<0.05). Spearman’s correlation analysis showed a positive correlation between plasma NO and ET levels and the VAS score.Conclusions Acupuncture plus massotherapy is an effective way to treat cervicogenic headache. Its improving effect on headache is closely related to changes in plasma NO and ET levels.
RESUMEN
BACKGROUND:The percutaneous pedicle screw technique effectively reduces the excessive injury of screw placement on paraspinal muscles, and promotes the recovery of the function of low back muscle after surgery. Minimal y invasive technique avoids some disadvantages such as large surgical trauma and more bleeding. Folding U-shaped hol ow pedicle screw has hol ow design and good distraction effect. After fixation, stress intensity, compression time, bending stiffness and torsional mechanical properties have been verified in the clinic. OBJECTIVE:To observe the clinical effect of folding U-shaped hol ow pedicle screw fixation combined with minimal access-posterior lumbar interbody fusion for single-level lumbar disc herniation. METHODS:Between January and December 2012, folding U-shaped hol ow pedicle screw fixation with minimal access-posterior lumbar interbody fusion was performed in 30 patients with lumbar disc herniation. The mean fol ow-up period was 12 months. Lumbago Visual Analog Scale, Oswestry Disability Index and imaging indicators were utilized to evaluate clinical therapeutic effects. RESULTS AND CONCLUSION:Preoperative Visual Analog Scale pain score and Oswestry Disability Index for al patients were 7.3±0.7 and 71.4±7.1, 2.9±0.7 and 29.8±3.6 at 3 days after surgery, showing significant differences. At 12 months, no significant difference in Visual Analog Scale pain score and Oswestry Disability Index was detected. Postoperative short-period fol ow-up demonstrated that al lumbar interbody fusion was achieved in one year. There was no complication such as implant failure or infection. These findings indicated that folding U-shaped hol ow pedicle screw fixation with minimal access-posterior lumbar interbody fusion for lumbar disc herniation showed good clinical therapeutic effects, high rate of interbody fusion and a low rate of complications and smal trauma.
