RESUMO
Objective@#To investigate the incidence and clinical characteristics of urothelial carcinoma (UC) accompanied with multiple primary carcinoma (MPC).@*Methods@#The clinical data of 121 UC patients with MPC in Peking University Third Hospital from January 2010 to May 2018 were retrospectly analyzed.@*Results@#UC patients with MPC accounted for 9.74% (121/1 242) of all the UC patients. The ratio of male to female patients was 2.10∶1 in the total MPC patients, but it was 1∶1 in the upper urinary tract MPC subgroup. The MPC patients were more common in elderly people, whose medium age was 68 (32-93) years old. Of all the location (131 person-time) of other tumors besides UC, the digestive system tumors occurred most frequently, accounting for 41.98% (55/131), followed by the urinary and male reproductive system tumors (20.61%, 27/131) and the female reproductive system (12.21%, 16/131). The proportion of the digestive system tumors (47.37%, 9/19) was the highest in the upper urinary tract MPC, with a total number of the other primary cancer of 19 person-time. However, the proportion of the urinary and male reproductive system tumors (37.14%, 13/35) was higher in the synchronous MPC group, with a total number of the other primary cancer of 35 person-time. Some patients had a history of radiotherapy and/or chemotherapy before UC was diagnosed. We also observed 2 cases of genetically confirmed Lynch syndrome. The median overall survival (mOS) of UC patients with MPC was 132 months, and the mOS of patients with UC as the first malignancy (including synchronous MPC and UC as the first malignancy in metachronous MPC) was 120 months. The mOS of the synchronous MPC group was 84 months, which was significantly shorter than 178 months of metachronous MPC group (χ2 =14.029, P<0.001).@*Conclusions@#The incidence of UC accompanied with MPC is not low, and the most common sites of MPC are the digestive system and reproductive system. Therefore, screening for MPC in UC patients, especially those with personal or family history of tumors, as well as elderly patients, may help early diagnosis and treatment of MPC patients and improve their prognoses.
RESUMO
Objective: Testicular mixed germ cell tumor is mixed with embryonal carcinoma, choriocarcinoma, yolk sac tumor, teratoma, seminoma and other two or more components of the testicular tumor, the clinical is relatively rare and high degree of malignancy, this article will summarize its clinical features and optimize its treatment.Methods: A retrospective analysis of the clinical data of 22 patients with testicular tumor mixed germ cell in Peking University Third Hospital from May 1994 to November 2016 was conducted using a combination of statistical analysis and discussion of the relevant literature.Results: The mean age of the 22 patients was (30.8±10.4) years and the rate of cryptorchidism was 13.6%.The maximum diameter of the tumor was (5.1±2.7) cm.The pathological results suggested that 12 cases (54.5%) contained two different germ cell tumor components, 7 cases (31.8%) contained 3 different tumor components, 2 cases (9.2%) contained 4 different tumor components, and 1 case (4.5%) contained 5 different tumor components.Tumor constituent analysis included yolk sac tumors(16 cases, 72.7%), mature teratoma (7 cases, 31.8%), immature teratoma (5 cases, 22.7%), embryonal carcinoma (17 cases, 77.3%) , choriocarcinoma (4 cases, 18.1%) and seminoma (6 cases, 27.3%).American Joint Committee of Cancer tumor staging indicated 19 cases of stage Ⅰ a tumor, 2 cases of stage Ⅱa tumor and 1 case of stage Ⅲa tumor.The mean values of human chorionic gonadotropin, alpha-fetoprotein and lactate dehydrogenase were 414.50 MIU/mL, 242.95 μg/L, 196.95 U/L (preoperative) and 17.20 MIU /mL, 90.20 μg/L, 183.70 U/L (postoperative within a year), and the comparison of the P values between the preoperative and the postoperative within a year were 0.079, 0.043 and 0.624.Fourteen patients underwent retroperitoneal lymph nodes dissection.Most patients lived with long-term survival (94.4%) after operation.Conclusion: Comprehensive treatment of radical orchiectomy with retroperitoneal lymphadenectomy combined with necessary radiotherapy or chemotherapy might help to control the tumor and achieve long-term survival for most patients with testicular mixed germ cell tumor.
RESUMO
Upper urinary tract calculi with infection is a quite difficult acute urologic emergency.And what is more, upper urinary tract obstruction after radical cystectomy following urinary diversion may be fatal in the vulnerable patients with this kind of situation.Postoperative anatomy and other factors affect the upper urinary tract calculi, and urinary tract infection greatly increased the risk.But it is particularly difficult to handle with patients with poor general condition and septic shock treatment, so how to optimize the selection program is worth further studying.A 65-year-old man was admitted to hospital for combining with renal and ureteral calculi after radical cystectomy (Bricker) in March 2017.The patient underwent transurethral resection of bladder tumor in the outer court because of the discovery of bladder tumor one year before, The postoperative pathology was high-grade papillary urothelial carcinoma and he underwent regular irrigation of the bladder.Because of tumor recurrence, he came to Peking University Third Hospital for further treatment in August 2016, and the examination of urinary tract CT indicated bladder can-cer;for bilateral multiple renal pelvis and renal calices calculi, he was given laparoscopic radical cystecto-my.After four months, due to sudden chill fever, he was hospitalized.After definite diagnosis, anti-inflammatory treatment combined with left nephrostomy was given.The two-stage lithotripsy was performed.After expansion of the original left renal fistula to 24 F(1 F=0.33 mm), 24 F sheath was inducted into the kidney.We introduced a flexible ureteroscopy into the channel down to the ureteral obstruction, where we found a 1 cm oval black brown stone obstructed.A guide wire was inducted through the stones down to ileal conduit in the right lower quadrant.Through the ureteroscopy, we made ureteral calculi broken into powder, and replaced the residual stones into the renal pelvis.Then we used the nephroscopy for lithotropsy in the pelvis, and finally we introduced a flexible cystoscopy for the residual stone.The operation was successful, the operation time was 181 min, and intraoperative bleeding was 10 mL.After operation, no residual stones were found in kidney, ureter, bladder (KUB) plain films.No operation complications were related to the urinary tract.Therefore, multiple endoscopy with combination therapy of upper urinary tract calculi following urinary diversion is safe and effective, and the reasonable choice with the advantages of each instrument can improve the stone clearance rate and shorten the operation time.This can be used as a useful complement to traditional treatment.
RESUMO
Objective To investigate the use of protective agent of gastric mucosa of helicobacter pylori quadraple therapy with pantoprazole based plus (Hp) positive duodenal ulcer intestinal microflora influence.Methods One hundred and twenty cases patients with Hp positive duodenal ulcer who were treated in Fuzhou University Hospital from September 2015 to September 2016 were selected and randomly divided into triplet group,quadruplet group,quadruplet + protective agent group.Triplet group were treated with pantoprazole 40 mg,oral amoxicillin 1 000 mg and oral clarithromycin 500 mg,2 times one day,for 14 d treatment.Quadruplet group were given triple group therapy plus bismuth potassium citrate 220 mg,2 times one day,oral treatment,for 14 d treatment.Quadruplet+protective agent group was given quadruple group therapy plus oral rebamipide 200 mg,3 times one day.The effect of Hp eradication and the distribution of intestinal microflora after treatment were compared.Results The eradication rate of Hp in triple group was 65.00％(26/40),in quadruplet was 82.50％(33/40),in quadruplet+protective agent group was 87.50％ (35/40),Hp eradication rate in quadruplet +protective agent group was higher than the triple group and quadruplet group (P ＜ 0.05).Overall symptom improvement rate in quadruplet + protective agent group(95.00％) was better than quadruple group(80.00％)and triplet Group (75.00％),the difference was significant (P＜ 0.05).After the eradication of gastric antrum,gastric body was higher than the number of Lactobacillus((1.7424±0.162) vs.(1.6796±0.223),t=4.023,P＜0.05).Ggastric acid bacillus,clostridium,and number of enterobacteriaceae were higher than the before eradication((1.742±0.162) lg cfu/mg vs.(1.505±0.250) lg cfu/mg,(2.106±0.083) lg cfu/mg vs.(2.010± ±0.131) lg cfu/mg,(2.030±0.119)lg cfu/mg vs.(1.609±0.399) lg cfu/mg),the differences were significant (t =3.225,3.174,3.571,P ＜ 0.05).The number of clostridium quasiballs lower than before eradication((1.654± 0.177) lg cfu/mg vs.(1.808 ± 0.300) lg cfu/mg),the difference was significant (t=2.896,P＜0.05).The body of the stomach Lactobacillus number was higher than before eradication((1.680± ±0.223) lg cfu/mg vs.(1.524±0.294) lg cfu/mg),the difference was significant(t =2.974,P ＜0.05).Clostridium quasiballs quantity was lower than before eradication ((1.694±0.216) lg cfu/mg vs,(1.8526± ±0.1193) lg cfu/mg),the difference was significant(t =1.332,P＜0.05).The number of fecal lactobacillus was higher than that before treatment ((40.406 ± 3.242) lg cfu/mg vs.(38.2034 + 3.036) lg cfu/mg),the difference was significant (t =3.115,P ＜ 0.05).Conclusion Pantoprazole based quadruple therapy plus the eradication rate of gastric mucosal protective agent can improve the use of Hp positive duodenal ulcer Hp,improve the overall symptoms,and it is more conducive to the balance of intestinal micro flora after Hp eradication.
RESUMO
Objective To evaluate the application of multi-slice computed tomographic coronary angiography in diagnosis of chronic total occlusion (CTO) of coronary artery.Methods Six hundred and thirty eight patients were diagnosed as CTO disease with coronary angiography (CAG) from June 2011 to December 2012 in Zhongshan Hospital;236 of them received multi-slice computed tomographic coronary angiography in 60 days before.Results In total 708 vessels of the 236 patients,244 vessels were proved totally occluded,128 (52.5％) of which were located in left anterior descending artery,31 (12.7％) were located in left circumflex coronary artery and 85 (34.8％) located in right coronary artery.Multi-slice computed tomographic coronary angiography was superior to CAG in judgment of stump anatomy (64.3％ vs.52.5％,F =7.09,P =0.010),plaque calcification (40.2％ vs.26.2％,F =10.68,P =0.001) and distal vessel interpretability (93.9％ vs.74.6％,F =34.06,P ＜ 0.001).There was no significant difference in judging side branch,tortuosity and lesion length between multi-slice computed tomographic coronary angiography and CAG (all P ＞ 0.05).Conclusion Multi-slice computed tomographic coronary angiography provides more detailed anatomy information of CTO lesions and is of value in diagnosis and treatment of CTO lesions.
RESUMO
Objective:To describe a feasible surgical technique for patients with renal cell carcinoma associated with a supradiaphragmatic tumor thrombus that avoids cardiopulmonary bypass procedure. Methods:We retrospectively analyzed 2 cases with right kidney tumor and tumor thrombus above the dia-phragm treated in April and August,2015.The two patients were both female,aged 73 and 67 years. The tumor sizes of right kidneys were 7.0 cm ×6.3 cm ×5.7 cm and 8.7 cm ×7.0 cm ×5.2 cm,and the tumor thrombuses were 1.3 cm and 1.8 cm above the diaphragm.The second patient had synchro-nous metastasis in right adrenal gland ,and the tumor thrombus arose from the adrenal vein but not the renal vein.Intraoperative transesophageal echocardiography (TEE)was used to assess real-time mobility of the thrombus.A modified chevron incision was used,the right kidney was mobilized laterally and pos-teriorly,and the renal artery was identified,ligated,and divided.The infradiaphragmatic inferior vena cava (IVC)was exposed and isolated by mobilizing the liver off the diaphragm or to the left (piggyback liver mobilization,case 2).The central diaphragm tendon was dissected or incised in the midline until the supradiaphragmatic intrapericardial IVC was identified and gently pulled beneath the diaphragm and into the abdomen.The tumor thrombus was then “milked”downward out of the intrapericardial IVC un-der the guidance of TEE.The distal and proximal IVC to the tumor thrombus,porta hepatis,and left re-nal vein were clamped.Tumor thrombus was removed from the IVC.The IVC was sutured and vascular clamps were placed below the major hepatic veins.Pringle’s maneuver was then released and hepatic blood drainage was permitted during closure of the remaining IVC.Related literature was reviewed.Re-sults:Complete resection was successful through the transabdominal approach without CBP in both pa-tients.Estimated blood loss was 1 500 mL and 2 000 mL,and 1 200 mL and 800 mL of blood were trans-fused.The postoperative courses were uneventful.Both patients subsequently underwent tyrosine-kinase inhibitor therapy.Both patients were alive without tumor recurrence or new metastasis during the follow-up of 6 months and 9 months.Conclusion:In selected cases,renal cell carcinoma extending into the IVC above the diaphragm can be resected without sternotomy,CBP or DHCA.
RESUMO
Objective To evaluate the effectiveness, safety and feasibility of the application of trans-radial thrombus aspiration in patient with heavy burden of thrombus receiving primary coronary interventional therapy. Methods 56 patients with acute coronary syndrome receiving primary coronary interventional therapy were enrolled and randomized to two groups. 31 patients received therapy of thrombus aspiration by Thrombuster II, while 25 patients received routine coronary interventional therapy. We compared the rate of major adverse cardiac event (MACE) in hospital, left ventricular ejection fraction (LVEF) one week post procedure and left ventricular end diastolic diameter (LVEDD), TIMI frame before and after procedure between two groups. Results The rate of MACE was signiifcantly (P<0.05) lower in patients receiving thrombus aspiration (3.3%) compared with routine PCI group (12.0%). LVEF and the rate of patients with TIMI Ⅲafter procedure were signiifcantly (P < 0.05) higher in patients receiving thrombus aspiration. There’s no significant difference in LVEDD between two groups. Conclusions There lies good safety and feasibility for applying thrombus aspiration combining direct PCI in patient with heavy burden of thrombus.
