Background: Acute normovolemic hemodilution (ANH) has been widely used to prevent the massive blood loss during hepatic carcinoma. The influences of ANH on coagulation function are still controversy, especially in elderly patients. The study observed ANH effects on coagulation function and fibrinolysis in elderly patients undergoing the disease. Materials and Methods: Thirty elderly patients (aged 60-70 yr) with liver cancer (ASA I or II) taken hepatic carcinectomy from February 2007 to February 2008 were randomly divided into ANH group (n=15) and control group (n=15). After tracheal intubation, patients in ANH group and control group were infused with 6% hydroxyethyl starch (130/0.4) and Ringer's solution, respectively. Blood samples were drawn from patients in both groups at five different time points: before anesthesia induction (T1), 30 min after ANH (T2), 1 h after start of operation (T3), immediately after operation (T4), and 24 h after operation (T5). Then coagulation function, soluble fibrin monomer complex (SFMC), prothrombin fragment (F1+2), and platelet membrane glycoprotein (CD62P and activated GP IIb/GP IIIa) were measured. Results: The perioperative blood loss and allogeneic blood transfusion were recorded during the surgery. The perioperative blood loss was not significantly different between two groups (p>0.05), but the volume of allogeneic blood transfusion in ANH group was significantly less than in control group ($350.0{\pm}70.7$) mL vs. ($457.0{\pm}181.3$) mL (p<0.01). Compared with the data of T1, the prothrombin time (PT) and activated partial thromboplastin time (APTT) measured after T3 were significantly longer (p<0.05) in both groups, but within normal range. There were no significant changes of thrombin time (TT) and D-dimer between two groups at different time points (p>0.05). SFMC and F1+2 increased in both groups, but were not statistically significant. PAC-1-positive cells and CD62P expressions in patients of ANH group were significantly lower than those at T1 (p<0.05) and T2-T5 (p>0.05). Conclusions: ANH has no obvious impact on fibrinolysis and coagulation function in elderly patients undergoing resection of liver cancer. The study suggested that ANH is safe to use in elderly patients and it could reduce allogeneic blood transfusion.

Background: Helicobacter pylori (H. pylori) is one of the risk factors for gastric cancer (GC). Any prognostic effect of HER-2 status in gastric lymph node metastasis in H. pylori positive cases is unknown. Materials and Methods: A total of 74 patients, 47 (64%) male, and 27 (34%) female, who had subtotal or total gastrectomy and also positive lymph nodes, were included in the study. Age range was 29-87 years, and median age was 58 years. HER-2 expression was assessed in both gastric resection samples and lymph node material with carcinoma metastasis of the same patient by immunohistochemistry (IHC) and silver in situ hybridization (SISH) methods. H. pylori status was examined in gastric materials of all patients. Relationships between HER-2 status in gastric cancers and lymph nodes and H. pylori status were investigated. Results: H. pylori was positive in 40 cases (54%), and negative in 34 (46%). While in the primary tissues of H. pylori positive cases, SISH positivity for HER-2 was observed in 13 cases (86%), SISH negativity was observed in 2 (14%), in metastatic lymph nodes 21 cases (72%) were SISH positive and 8 cases (28%) were SISH negative (P=0.005 and P=0.019, respectively). Initial CEA values were high in 18 cases (78%) with positive H. pylori and in 5 cases (22%) with negative H. pylori (P=0.009). While SISH data of patients were negative in 59 cases (80%) and positive in 15 cases (20%) in primary tissues, they were negative in 56 cases (75%) and positive in 18 cases (25%) in lymph nodes. Discrepancy between primary tissue and lymph node results was detected in 3 cases, in which SISH was negative in the primary tissue and HER-2 expression was positive in the lymph nodes. Conclusions: Clinical progression was poor in H. pylori positive cases with HER-2 negativity in primary gastric tissue, but HER-2 positivity in the lymph nodes. SISH positivity can be expected in H. pylori positive cases, and it may be predicted that these cases can benefit from trastuzumab treatment.

Purpose: To investigate the patterns of recurrence in patients with neuroblastoma treated with radiation therapy to the primary tumor site. Materials and Methods: We retrospectively analyzed patients with high-risk neuroblastoma managed with definitive treatment with radiation therapy to the primary tumor site between January 2003 and June 2017. These patients underwent three-dimensional conformal radiation therapy or intensity-modulated radiation therapy. A total of 14-36 Gy was delivered to the planning target volume, which included the primary tumor bed and the selected metastatic site. The disease stage was determined according to the International Neuroblastoma Staging System (INSS). We evaluated the recurrence pattern (i.e., local or systemic), progression-free survival, and overall survival. Results: A total of 40 patients with high-risk neuroblastoma were included in this study. The median patient age was 4 years (range, 1 to 11 years). Thirty patients (75%) had INSS stage 4 neuroblastoma. At the median follow-up of 58 months, there were 6 cases of local recurrence and 10 cases of systemic recurrence. Among the 6 local failure cases, 4 relapsed adjacent to the radiation field. The other 2 relapsed in the radiation field (i.e., para-aortic and retroperitoneal areas). The main sites of distant metastasis were the bone, lymph nodes, and bone marrow. The 5-year progression-free survival was 70.9% and the 5-year overall survival was 74.3%. Conclusion: Radiation therapy directed at the primary tumor site provides good local control. It seems to be adequate for disease control in patients with high-risk neuroblastoma after chemotherapy and surgical resection.

Thyroid carcinoma ranks low in incidence and as a cause of death when compared to carcinomas arising in the other site. With adequate surgical treatment, the prognosis of operable thyroid carcinoma is good. However, the extent of surgical resection in treatment of thyroid cancer remains still controversy. The aim of this study was to assess the results of thyroid cancer patients treated surgically and to analyze the prognostic factors affecting survival and to improve the survival rate. We retrospectively analyzed the outcome of a total of 278 thyroid cancer patients treated surgically at Inje University Paik Hospital from 1980 to 1995 and followed for 1 to 16 years. There were man in 47 and woman in 231 patients with age range of 14 to 79 years(mean 42 years). Histopathologic findings were papillary carcinoma in 233, follicular carcinoma in 33, mixed carcinoma in 7, medullary carcinoma in 2, and undifferentiated carcinoma in 3 patients, respectively. Operative procedures were unilateral lobectomy in 111, subtotal thyroidectomy in 100, and total thyroidectomy in 67 patients. Central node dissection was performed in 92, modified neck disseciton in 62, radical neck dissection in 28, and no node dissection in 96 patients. Thyroid hormone was administered for the period of 3 to 5 years to suppress endogenous TSH production. Overall 5-year survival rate according to Kaplan-Meier method was 91.1%. Independently, significant factors affecting the prognosis were age at diagnosis, tumor size, pathologic type, tumor stage, lymph node metastasis, angioinvasion, extrathyroidal extension, and 'risk' group category. but, the prognosis were not influenced by sex and capsular invasion. Patients at low risk or with small size carcinomas had long survival over 5 years with only lobectomy. Lymph node dissection was carried out with a limited type in no jugular metastasis, radical neck dissection was performed only therapeutically in proved jugular node metastasis. Fifteen patients were dead of tumor recurrence after surviving for three months to two and half years, and the cause of death was local recurrence in nine, bone metastasis in four and lung metastasis in two patients. In conclusion, more extensive surgery including total thyroidecotmy and systematic compartment-oriented dissection of the lymph node metastases in patient at high-risk group will results in better survival and lower recurrence rate.

Purpose : To evaluate the functional and radiographic outcome of the modified Bosworth method in the surgical treatment of acute type V acromioclavicular joint dislocation. Materials and Methods: From June 1995 to May 1998, 20 patients were operated on for acute and complete acromioclavicular dislocation(Rockwood type V). The operative technique includes fixation of the coracoclavicular joint with Bosworth screw or 6.5mm cancellous screw and imbrication of trapezius and deltoid muscles. The average age was 34 years(range, 19 to 51 years). These 20 patients with an average follow-up of 18months, were evaluated clinically using the UCLA scoring system. Additional radiographical assessment was performed with stress radiographs. Results: Excellent or good clinical results were obtained in 95%(19 cases). And the average coracoclavicular interval ratio was decreased from 3.31(2.2-6.0) to 1.13(1-1.4) in stress radiographs. There were 4 cases of hetero­topic calcification postoperatively but there was no correlation with clinical result. Posttraumatic A-C joint arthritis was developed in one case. In that case, the distal clavicular resection was done under the arthroscopic technique. Conclusion: The severe displacement observed with type V injuries is incompatible with normal shoulder function if the shoulder is left in its displaced position. In type V injuries, significant damage to the deltoid and trapezius musculature and overlying fascia occurs, therefore open reduction and good fixation must be obtained with imbrication of trapezius and deltoid muscles. In our type V acute complete acromioclavicular dislocation, the modified Bosworth technique provides excellent results with a low complication rate.

Background/Objectives: Papillary thyroid carcinoma (PTC) has generally an indolent character with a good prognosis. However, recurrence remains a major concern for the patients during their lifetime. Despite the slowly progressing character of PTC, recurrence can occur within a short period after initial surgery. This study aimed to determine the clinical findings and cause of recurrence in patients who underwent re-operative surgery due to neck node recurrence by reviewing the CT (computed tomographic) scan imaging of the recurrence of PTC retrospectively. Materials & Methods: We reviewed the medical records of patients referred to Ajou University Hospital from January 2002 to January 2018. All patients had re-operative surgery due to neck node recurrence and CT scan results of preoperative evaluation and postoperative follow up. Over this period, 110 patients who underwent re-operation due to neck node recurrence with a CT scan were included in our cohort, resulting in a total of 220 re-operations. Results: The time from initial operation to first re-operation was examined in 110 patients. The median time to re-operation was 28 months, with a range of 4 months to 186 months. Most re-operations (82.7%) occurred within the first five years, 43.6% were in the first two years from the initial surgery. The result of the retrospective CT review showed newly developed cases (21,19.1%), missed diagnosis cases (42,38.2%), real recur cases after surgery (33,30.0%), and remnant lymph nodes (LNs) cases (14,12.7%). We further sub-analyzed 14 cases with remnant LNs. Reasons for remnant LNs included insufficient operation (N=5) and beyond general surgical extent. (N=9). Conclusion: Re-operation due to cervical lymph node recurrence is mostly a persistent disease. They included a missed diagnosis and incomplete operation. These finding may reduce the reoperation of cervical lymph node recurrence by accurate preoperative evaluation and complete surgical resection at the initial surgery.
