2.Multidisciplinary Management of the Locally Advanced Unresectable Non-Small Cell Lung Cancer.
The Journal of the Korean Society for Therapeutic Radiology and Oncology 2004;22(1):1-10
Locally advanced (Stage III) non-small cell lung cancer (NSCLC) accounts for approximately one third of all cases of NSCLC. Few patients with locally advanced NSCLC present with disease amenable to curative surgical resection. Historically, these patients were treated with primary thoracic radiation therapy (RT) and had poor long term survival rates, due to both progression of local disease and development of distant metastases. Over the last two decades, the use of multidisciplinary approach has improved the outcome for patients with locally advanced NSCLC. Combined chemoradiotherapy is the most favored approach for treatment of locally advanced unresectable NSCLC. There are two basic treatment protocols for administering combined chemotherapy and radiation, sequential versus concurrent. The rationale for using chemotherapy is to eliminate subclinical metastatic disease while improving local control. Sequential use of chemotherapy followed by radiotherapy has improved median and long term survival compared to radiation therapy alone. This approach appears to decrease the risk of distant metastases, but local failure rates remain the same as radiation alone. Concurrent chemoradiotherapy has been studied extensively. The potential advantages of this approach may include sensitization of tumor cells to radiation by the administration of chemotherapy, and reduced overall treatment time compared to sequential therapy; which is known to be important for improving local control in radiation biology. This approach improves survival primarily as a result of improved local control. However, it doesn't seem to decrease the risk of distant metastases probably because concurrent chemoradiation requires dose reductions in chemotherapy due to increased risks of acute morbidity such as acute esophageal toxicity. Although multidisciplinary therapy has led to improved survival rates compared to radiation therapy alone and has become the new standard of care, the optimal therapy of locally advanced NSCLC continues to evolve. The current issues in the multidisciplinary management of locally advanced NSCLC will be reviewed in this report.

To identify significant prognostic factors in patients undergoing simple hysterectomy in the presence of invasive cervical cancer, the records of 45 patients who had taken such a procedure between 1993 and 1997 were reviewed. Overall relapse-free survival and 5-year survival rates were 91.1 and 92.1%, respectively. Factors found to be significantly related to survival were the retrospectively determined stage(p=0.0000), the presence of residual disease(p=0.0001), and cell type(p=0.0000). By multivariate analysis, factor emerging as significantly detrimental to survival was the cell type. The presence of residual disease was a marginally significant factor(p=0.067). The expectations for survival of patients with residual tumor mass and/or with adenocarcinoma after simple hysterectomy appear to be markedly worse than those with others, so radical reoperation should be considered in those patients.

Ultrasonography is a predominantly accurate, relatively simple unique diagnsotic method of obstructive jaundice. The ultrasonographic findings of obstructive jaundice are dilated intra- and extrahepatic duct with intraluminal hyperreflective echo or mass in and/or around the bile duct. The superiority of high resolution real time ultrasonography for the diagnosis of obstructive jaundice is based on the easy detectability of extra-and intrahepatic bile ducts by its multiple sectional images in a short time, the flexibility of probe and the small crystal size. Author evaluated real time sonographic findings 46 obstructive jaundice patients confirmed by surgery or radiographical examinations. The results were: 1. Diameter of extrahepatic duct in obstructive jaundice were varied from normal to 4.0 cm, mostly 8 to 10 mm in diameter (26%). Degree of dilatation of biliary duct appeared more prominent in cancer patients than any other causes of obstruction. 2. The site of obstruction was detected in85% (39/46) and its common site was common bile duct in 63% (29/46). 3. The diagnostic accuracy of choledocholithiasis and cancer was 82% (22/27) and 44% (4/9), respectively. Diagnostic accuracy of the real time ultrasonography in obstructive jaundice was over all 75% (34/46).

This study examined the late pathological finding, clinical manifestation, and mortality in thirty-two rats with cerebral infarction induced by common carotied artery ligation. Thirty-two rats were divided into three group : Group A-a unilateral common carotid artery ligation group of twelve animals, Group B-a total common carotid artery ligation one side and partial common carotid artery ligation another side of eighteen animals, and Group C-bilateral common carotid arteries ligation of two animal. All animals surviving for 3 weeks were sacrified by intracardial injection of 2 M KCI 5cc and 2.5cc of 2% T.T.C. solution was infused into each common carotid arteries. The brain was rapidly rmoved and sectioned coronally and examined with the aid of a stereoscopic microscope for degree of T.T.C. stain and infarction. Brain was fixed and examined histologically. The results were as follows : 1) Mortality rate of each group : a unilateral common carotid artery ligation group was 16.67%, a total. Common carotid artery ligation on side and partial common carotid artery ligation another side group was 77.78%, and bilateral common arteries ligation group was 100%. 2) Clinical manifestation was showed as follows : hemiparesis, circling movement, abnormal seizure like activity, and ptosis. 3) Percent hemispheric volume infarction(%HVI) was 40%(mean value) in unilateral total common carotid artery ligation and 60% in total ligation one side and 46.25% in partial ligation another side. 4) The pathological change was signigicantly visible in bilateral ligation group.

9.Multimodal therapy for locally advanced prostate cancer: the roles of radiotherapy, androgen deprivation therapy, and their combination.
Radiation Oncology Journal 2017;35(3):189-197
Locally advanced prostate cancer (LAPC) is defined as histologically proven T3–4 prostatic adenocarcinoma. In this review, we define the individual roles of radiotherapy (RT), short-term (ST-) and long-term (LT-) androgen deprivation therapy (ADT), and their combination in multimodal therapy for LAPC. Despite limitations in comparing the clinical outcomes among published papers, in the present study, a trend of 10-year clinical outcomes was roughly estimated by calculating the average rates weighted by the cohort number. With RT alone, the following rates were estimated: 87% biochemical failure, 34% local failure (LF), 48% distant metastasis (DM), 38% overall survival (OS), and 27% disease-specific mortality (DSM). Those associated with ADT alone were 74% BCF, 54% OS, and 25% DSM, which appeared to be better than those of RT alone. The addition of ADT to RT produced a notable local and systemic effect, regardless of ST- or LT-ADT. The LF rate decreased from 34% with RT alone to 21% with ST-ADT and further to 15% with LT-ADT. The DM and DSM rates also showed a similar trend among RT alone, RT+ST-ADT, and RT+LT-ADT. The combination of RT+LT-ADT resulted in the best long-term clinical outcomes, indicating that both RT and ADT are important parts of multimodal therapy.
