PURPOSE: This study aimed to quantitatively measure the movement of tumors in real-time and evaluate the treatment accuracy, during the treatment of a liver tumor patient, who underwent radiosurgery with a Synchrony Respiratory motion tracking system of a robot CyberKnife. MATERIALS AND METHODS: The study subjects included 24 liver tumor patients who underwent CyberKnife treatment, which included 64 times of treatment with the Synchrony Respiratory motion tracking system (Synchrony(TM)). The treatment involved inserting 4 to 6 acupuncture needles into the vicinity of the liver tumor in all the patients using ultrasonography as a guide. A treatment plan was set up using the CT images for treatment planning uses. The position of the acupuncture needle was identified for every treatment time by Digitally Reconstructed Radiography (DRR) prepared at the time of treatment planning and X-ray images photographed in real-time. Subsequent results were stored through a Motion Tracking System (MTS) using the Mtsmain.log treatment file. In this way, movement of the tumor was measured. Besides, the accuracy of radiosurgery using CyberKnife was evaluated by the correlation errors between the real-time positions of the acupuncture needles and the predicted coordinates. RESULTS: The maximum and the average translational movement of the liver tumor were measured 23.5 mm and 13.9+/-5.5 mm, respectively from the superior to the inferior direction, 3.9 mm and 1.9+/-0.9 mm, respectively from left to right, and 8.3 mm and 4.9+/-1.9 mm, respectively from the anterior to the posterior direction. The maximum and the average rotational movement of the liver tumor were measured to be 3.3degrees and 2.6+/-1.3degrees, respectively for X (Left-Right) axis rotation, 4.8degrees and 2.3+/-1.0degrees, respectively for Y (Cranio-Caudal) axis rotation, 3.9degrees and 2.8+/-1.1degrees, respectively for Z (Anterior-Posterior) axis rotation. In addition, the average correlation error, which represents the treatment's accuracy was 1.1+/-0.7 mm. CONCLUSION: In this study real-time movement of a liver tumor during the radiosurgery could be verified quantitatively and the accuracy of the radiosurgery with the Synchrony Respiratory motion tracking system of robot could be evaluated. On this basis, the decision of treatment volume in radiosurgery or conventional radiotherapy and useful information on the movement of liver tumor are supposed to be provided.

This study was designed to evaluate the usefulness of pudendal nerve block in the dorsal approach under EMG monitoring. The patient is placed in the prone position. The location of pudendal nerve is identified using the both ischial tuberosities and greater trochanter. We have performed the pudenal nerve block with 5% phenol solution, under the EMG monitoring. The patient was able to void with percussion method. There has been no impairment in urinary continence. We experienced an excellent effect of bilateral pudendal nerve block in the dorsal approach, under EMG montoring, using 5% phenol solution in detrusor sphincter dyssynergia of neurogenic bladder.

PURPOSE: The E-cadherin gene, located on chromosome 16q22, may play principal roles in cell adhesion with the loss of E-cadherin expression leading to a propensity for a great number of malignant properties. The loss of heterozygosity (LOH) on 16q22 has rarely been studied in invasive ductal carcinomas. Our objectives were to evaluate the LOH of E-cadherin and the protein expression in invasive ductal carcinomas and their correlation with various clinicopathological factors. METHODS: The LOH analysis was performed using polymerase chain reactions with three polymorphic microsatellite markers (D16S419, D16S3106 and D16S498) in 50 surgically resected tumors and their non-tumorous counterparts. The E-cadherin protein expression was studied using immunohistochemistry. RESULTS: The LOH and loss of protein expression were detected in 54% and 46% of the tumors, respectively. There was no LOH or protein loss detected in the non-tumor lesions. The LOH results were well correlated with the tumor size and lymph node metastasis. The protein loss results were well correlated with tumor histological grade. No correlation was found between LOH and protein loss. CONCLUSION: These results suggest that the LOH of E-cadherin may be associated with tumor metastasis and tumor progression and E-cadherin protein loss may be related with the dedifferentiation in some portions of invasive ductal carcinomas. We propose the LOH of E-cadherin and protein loss may contribute to tumor progression by independent mechanism.

Coarctation of aorta is a rare vascular disorder which is one of causes of secondary hypertension. Since the early 1990s stenting in the coarctation of aorta has been introduced as an alternative treatment method, there were a few cases which were treated by stent implantation for the coarctation of the aorta in Korea. But the case which was treated using stent in congestive heart failure with pulmonary edema has never been reported. We report on successful management of a 64-year-old female patient, who presented with acute heart failure and pulmonary edema due to severe aortic coarctation. After endotracheal intubation, aortogram was performed, which revealed a severe narrowing in the distal thoracic aorta with a peak systolic pressure gradient of 100 mmHg across the lesion. Stent implantation was performed with 24x100 mm self-expandable Nitinol-S stent after predilation with 10x40 mm balloon. After stenting, patient's symptom and sign of congestive heart failure were remarkably improved and endotracheal intubation tube was able to be removed. And no significant adverse cardiac events observed during a nine-month clinical follow-up.

In the 2021 series, we not only summarized the major clinical research advances in gynecologic oncology but also added discussions to every part, based on communications at the conference. A review of cervical cancer included adjuvant treatments such as radiation and chemoradiation (concurrent or sequential) after radical hysterectomy in early cervical cancer, and immune checkpoint inhibitors in advanced, recurrent, and metastatic disease. Ovarian cancer research included studies of secondary cytoreductive surgery in platinum-sensitive recurrent ovarian cancer, and various trials of immune checkpoint inhibitors with or without vascular endothelial growth factor inhibitors and conventional chemotherapy. The rechallenge of poly (ADP-ribose) polymerase inhibitor maintenance in heavily pretreated ovarian cancer were also addressed. For uterine corpus cancer, dostarlimab (anti-programmed cell death protein 1 antibody) alone, or a tyrosine kinase inhibitor in combination with pembrolizumab for advanced, metastatic, or recurrent endometrial cancer were reviewed. The survival differences between the intensive and minimalist follow-up protocols were also described. In this review, we compared salpingectomy with delayed oophorectomy and salpingo-oophorectomy in terms of quality of life in BRCA 1 and 2 pathogenic variant carriers.

BACKGROUND AND OBJECTIVES: The level of cardiac specific troponin (cTn) may be important in patients with acute coronary syndrome (ACS), but with normal electrocardiography (ECG). SUBJECTS AND METHODS: Three hundred and nineteen patients (61+/-11 years, M:F=212:107), with ACS and normal ECG, who underwent a diagnostic coronary angiogram (CAG), between July 2000 and June 2001, were analyzed according to their cTn level. The clinical characteristics, initial CAG findings and major adverse cardiac events (MACE), during a one-year clinical follow-up, were compared between positive and negative cTn groups. RESULTS: Of the enrolled patients, 191 had a negative cTn (group A, 61+/-10 years, M:F=131:60), and 128 a positive cTn (group B, 60+/-11 years, M:F=81:47), and 176 (55.2%) were shown to have significant coronary artery stenosis on CAG. There were no significant differences in risk factors between the two groups. The mean left ventricular ejection fraction was 64+/-9%, and was lower in group B than in group A (59+/-10% vs. 67+/-7%, p<0.05). cTn positivity was associated with the percentage of significant coronary artery stenosis present (88% vs. 32%, p<0.05), a smaller minimal luminal diameter (1.09+/-0.44 mm vs. 2.68+/-0.33 mm, p<0.05) and a larger diameter of stenosis (68+/-6% vs. 44+/-6%, p<0.05). A multi-vessel lesion was more common in group B than in group A (58.3% vs. 30.3%, p<0.05). During the one-year follow-up period, 36 patients developed MACE, resulting in 3 deaths, 7 acute myocardial infarctions and 34 patients with restenosis. MACE was observed in 9 patients of group A and in 27 of group B (4.7% vs. 21.1%, p<0.05). CONCLUSION: The troponin levels are valuable for the early diagnosis, and prediction of the long-term prognosis, in patients with ACS and a normal ECG.

A 55-year old male presented with chest and abdominal pain for four hours. One day prior to admission he had received chemotherapeutic agents comprising 130 mg cisplatin and 5,200 mg 5-Fluorouracil for nasopharyngeal carcinoma. EKG showed ST elevations in the leads II, III and aVF. The levels of cardiac enzymes were elevated [creatine kinase (CK) 1129 U/L, CK-MB 180 U/L, troponin T 1.23 ng/mL and troponin I 23.29 ng/mL]. Urokinase was administered at the emergency room, but the patient's chest pain continued with persistent ST segment elevations. Urgent coronary and renal angiograms revealed thrombotic occlusive lesions in the distal right coronary and right renal arteries. Percutaneous transluminal renal angioplasty using 6.0x20 mm balloon was performed for the renal artery. However, filling defects and distal renal flow were not improved and so Abciximab (ReoPro(r)) was administered. Follow-up coronary and renal angiograms on the fifth hospital day showed no filling defects with good distal flow in both right coronary and renal arteries.

A 28-year old male presented with chest pain of two hours duration. He had histories of 10 years smoking and 2 years of nephrotic syndrome, due to minimal change disease. His EKG showed marked ST segment elevations in the V3-6, I, II, III and aVF leads. The levels of cardiac enzymes were increased (CK: 481 U/l, CK-MB: 96 U/l and Troponin I: 4.8 ng/mL). The prothrombin and activated partial promboplastin times were normal. Accelerated tissue type plasminogen activator (100 mg) was administered at the emergency room, but his chest pain continued, with persistent ST segment elevations. An urgent coronary angiograph revealed huge multiple filling defects, suggestive of thrombi in the proximal left anterior descending artery (LAD), with thrombolysis in the myocardial infarction (TIMI) flow. A rescue percutaneous coronary intervention was performed using repeated angioplasties with a 3.0 mm balloon. However, the filling defects and distal LAD flow did not improve. We administered Abciximab (ReoPro(r)), and the LAD flow improved to a TIMI III flow, with resolution of the thrombus in the LAD. His clinical course was uneventful after discharge, and a left coronary angiogram, at the 6-month follow-up, showed no filling defects, with the TIMI III flow maintained.
