ObjectiveTo explore the safety-related factors for total thyroidectomy in differentiated thyroid carcinoma. MethodsThe clinical data of 72 patients with differentiated thyroid carcinoma treated by total thyroidectomy from January 2002 to January 2010 were retrospectively analyzed, the laryngeal recurrent nerve injury and hypoparathyroidism were observed. ResultsThe incidences of hypoparathyroidism and laryngeal recurrent nerve injury were 15.28% （11/72) and 4.17%（3/72）, respectively. The hypoparathyroidism was significantly related to the thyroid reoperation, the lymph nodes metastases of central compartment, or the extraglandular invasion of the primary tumor (Plt;0.05), but not to the dissection of neck lymph nodes (Pgt;0.05). The laryngeal recurrent nerve injury was not relative to those factors (Pgt;0.05). ConclusionThe safetyrelated factors of total thyroidectomy in differentiated thyroid carcinoma include thyroid reoperation, the lymph node metastasis of central compartment, and the extraglandular invasion of the primary tumor.
Objective To explore the value of dual-channel anastomosis of residual stomach and jejunum in radical resection of the upper gastric cancer. Methods Forty patients with upper gastric cancer had undergone proximal gastrectomy and dualchannel digestive tract reconstruction, including esophagus-jejunum side to side anastomosis, residual stomachjejunum anastomosis, and jejunum-jejunum anastomosis. Results The cutting margin away from tumor in all the cases was more than 5 cm and no carcinoma residual. The number of lymph nodes dissection was 21±6, reaching the requirement of D2 radical surgery. There was no case appearing complications such as anastomotic leakage, obstruction or bleeding. Barium meal examination after operation showed that most of barium was directly into the jejunum, the remaining went through the duodenum into the jejunum without gastroesophageal reflux. Followed up 6-30 months with average 18 months, there were no visible reflux esophagitis in all the cases, and only 1 case appeared minor dumping syndrome. The hemoglobin increased and the quality of life was satisfactory after operation. Conclusions In regard to dual-channel anastomosis of residual stomach and jejunum, resection range is reasonable, dissection scope accords with the protocol and residual stomach has a certain pouch effect. The anastomosis has a favorable prevention from reflux esophagitis and dumping syndrome and retains the duodenum pathway, so that improves the quality of patients’ life and is a relatively ideal digestive tract reconstruction.
Objective To explore clinicopathologic features and prognostic factors of different pathological types of advanced gastric cancer. Methods The clinicopathologic data of 98 patients with advanced gastric cancer who underwent radical gastrectomy in Suqian People’s Hospital, Nanjing Drum Tower Hospital Group, Affiliated to Nanjing University Medical School in 2011 were analyzed retrospectively. There were 53 cases of gastric adenocar-cinoma, 30 cases of mucinous adenocarcinoma, and 15 cases of signet ring cell carcinoma among them. The differences of clinicopathologic characteristics and prognosis were compared among different pathological types of advanced gastric cancer. Results ① There were no significant differences in terms of the gender, age, nerve invasion, and degree of differentiation among the three groups (P>0.05), there were significant differences in terms of the tumor diameter, tumor location, radical surgery type, regional lymph node metastasis, lymphatic cancer embolus, depth of invasion, and pTNM stage among the three groups (P<0.05). ② The results of the univariate analysis showed that the prognosis of gastric adenocarcinoma was associated with the tumor diameter, tumor location, radical surgery type, regional lymph node metastasis, depth of invasion, or pTNM stage (P<0.05); the prognosis of mucinous adenocarcinoma was associated with the radical surgery type, regional lymph node metastasis, or pTNM stage (P<0.05); the prognosis of signet ring cell carcinoma was associated with the regional lymph node metastasis, depth of invasion, and pTNM stage (P<0.05). ③ The results of the Cox multivariate analysis showed that the tumor location (P=0.016), regional lymph node metastasis (P=0.042), invasion depth (P=0.021), and pTNM stage (P=0.009) were the independent risk factors of prognosis for the gastric adenocarcinoma; the regional lymph node metastasis was the independent risk factor of prognosis for gastric mucinous adenocarcinoma (P=0.000); the tumor invasion depth (P=0.032) and regional lymph node metastasis (P=0.002) were the independent risk factors of prognosis for signet ring cell carcinoma. ④ The follow-up time was 60 months. The median follow-up time was 32 months in the gastric adenocarcinoma, 43 months in the mucinous adenocarcinoma, 23 months in the signet ring cell carcinoma, the 5-year accumulated survival rate was 30.2%, 23.3%, and 26.7% respectively. The comparison of survival curves of these three different pathological types of gastric cancer had no significant difference (P=0.131). Conclusion Clinical and pathological features of patients with different pathological types of advance gastric cancer present some differences, and prognostic factors are also different, but regional lymph node metastasis is a common prognostic factor for different pathological types of advanced gastric cancer.
Objective To explore the feasibility of clinical application of hepatic artery （HA） or proper hepatic artery （PHA） anastomosing with superior mesenteric artery （SMA） and internal iliac vein （IIV） anastomosing with superior mesenteric vein （SMV） or portal vein （PV） in the extended pancreaticoduodenectomy combined with vascular resection．Methods The HA，PHA，SMA， SMV， PV， and IIV were dissected on 20 adult corpses， and the length， thickness，and lumen diameter of blood vessels were measured and compared with the results of multislice spiral CT scan，magnetic resonance angiography，or color Doppler in 25 patients with pancreatic head carcinoma．The extended pancreaticoduodenectomy was carried out on 5 patients of pancreatic head carcinoma with vascular invasion according to the mathcing results，and the reconstructions of HA or PHA with SMA and IIV with SMV or PV were performed．Results According to autopsy，HA-PHA was （5.50±1.50） cm in length，（0.20±0.01） mm in thickness，（5.02±1.32） mm in lumen diameter；and SMA was （4.00±1.00） cm in length，（0.21±0.01） mm in thickness，（6.05±1.06） mm in lumen diameter．The lumen diameter of left IIV，right IIV，and PV or SMV was （11.06±0.16） mm，（11.10±0.13） mm，and （11.56±0.20） mm，respectively．The thickness of left IIV，right IIV，and PV or SMV was （0.10±0.01） mm，（0.10±0.02） mm，and （0.10±0.02） mm，respectively．The multislice spiral CT scan，magnetic resonance angiography，color Doppler，and selective arteriography in vivo showed that the thickness and lumen diameter of HA-PHA and SMA were wider （0.1 mm and 0.3 mm） than those of the autopsy results，and there were no statistic significances （P＞0.05），but the length of HA-PHA was longer （1－2 cm） than that of SMA，and there was statistic significance （P＜0.05）. The survival of 5 patients with extended pancreaticoduodenectomy combined with PHA or SMA and IIV-PV/SMV resection and reconstruction was longer than that of palliative surgery patients or giving-up patients at the same period，and no long-term complications occurred．Conclusions The vascular invasion of pancreatic head carcinoma is not an absolute contraindication of radical pancreaticoduodenectomy．The survival of 5 patients with vascular invasion of pancreatic head carcinoma in this group is prolonged by extended pancreaticoduodenectomy combined with vascular resection and reconstruction as compared with palliative surgery group at the same period．HA，PHA，and IIV are the best autologous vascular alternative materials without more complications． Being familiar with regional anatomy will guide the surgeons in extended pancreaticoduodenectomy.
ObjectiveTo explore the expressions of survivin, p53, and Ki67 in recurrence or metastasis breast cancer tissue, and explore their correlations and clinical significance. MethodsEighty-six patients with the chest wall local recurrence, axillary or supraclavicular lymph node metastases get treated in this hospital between January 2005 and January 2010 were excised and the expressions of survivin, p53, and Ki67 were detected by immunohistochemistry test, then compared them between the recurrence and metastasis breast cancer tissues and the primary breast cancer tissues. ResultsThe positive expression rate of survivin, p53, and Ki67 in the recurrence and metastasis breast cancer tissues were significantly higher than those in the primary breast cancer tissues, survivin: 90.70% (78/86) versus 61.63% (53/86), χ2=20.014 895, Plt;0.001; p53: 68.60% (59/86) versus 52.33% (45/86), χ2=4.766 968, Plt;0.05; Ki67: 62.79% (54/86) versus 46.51% (40/86), χ2=4.597 927，Plt;0.05. The positive expression rates of survivin in the recurrence and metastasis patients with p53, Ki67 negative expression were significantly higher than those of the primary breast cancer tissue (70.37% versus 24.39%, χ2=14.071 113, Plt;0.05; 75.00% versus 39.13%, χ2=6.540 373, Plt;0.05). The correlation coefficient of survivin with p53 and Ki67 positive expressions in the recurrence and metastasis breast cancer tissue and the primary breast cancer tissue were 0.876 214, 0.773 643 and 0.725 164, 0.698 112, respectively, Plt;0.05. ConclusionThe positive expression rates of survivin, p53, and Ki67 which increase in recurrence and metastasis breast cancer tissue indicate bad prognosis.
ObjectiveTo explore the clinical significance of hepatectomy combined with vascular reconstruction in hilar cholangiocarcinoma with vascular invasion. MethodsThe clinical data of 62 cases of hilar cholangiocarcinoma with vascular invasion in Suqian People's Hospital of Nanjing Drum-Tower Hospital Group from January 2006 to January 2014 were analyzed retrospectively. All cases were divided into two groups according to assessment of surgical trauma tolerance, nutritional status, and family's wishes. Thirty-three cases underwent hilar cholangiocarcinoma radical operation and hepatic artery combined with portal vein resection and reconstruction (combined resection group), while 29 cases of hilar cholangiocarcinoma underwent palliative surgery for treating jaundice in synchronization (palliative operation group). ResultsThe median survivals in combined resection group and palliative operation group was 26.3 and 9.6 months, respectively. The survival rates of 1-year, 2-year, and 3-year between combined resection group and palliative operation group were 84.85% vs. 26.32%, 66.67% vs. 15.79%, and 42.42% vs. 0, respectively, there were significant differences between both groups in survival time and survival rate (t=4.470, P=0.000; χ2=28.338, 20.348, and 15.891, P=0.000). Among of 33 cases in combined resection group, postoperative complications occurred in 9 cases, the rate of complications was 27.27% and the mortality rate in perioperative period was 3.03%; while postoperative complications in palliative operation group occurred in 5 cases, the rate of complications was 17.24%, no case died in the perioperative period. There were no significant difference between both groups in the rate of postoperative complications and the mortality rate in perioperative period (χ2=0.888, P=0.346; χ2=0.893, P=0.345). ConclusionsHepatectomy combined with vascular resection and reconstruction can significantly improve the radical resection (R0) rate of HCCA, and greatly increase the 1-year, 2-year, and 3-year survival rates of patients. Furthermore, complications can be controlled, and the mortality rate in perioperative period does not increase.
