Recurrence of colorectal cancer after apparently curative resection remains common, with reported relapse rates of up to 40%. Because complete resection of solitary metastases or local recurrence may improve long-term survival, surgical management of such cases has become increasingly aggressive but has led to only modest survival benefit. The limitations of current approaches based on structural imaging are well documented, with over half of the patients who are thought suitable for curative surgery being found to have unresectable disease at operation. Therefore, better preoperative assessment is crucial. The increasing use of FDG-PET as an oncologic staging investigation has significantly improved the assessment of patients with suspected colorectal cancer recurrence. Several studios show that substantial and largely appropriate changes in patient management occur, often soaring patients the significant morbidity and mortality associated with aggressive but futile therapies while also saving scarce community resources. Nevertheless, the clinical relevance of these findings has still been questioned. The utility of PET in routine clinical practice will likely depend on its ability to provide incremental information compared with CT in selected patients rather than to serve as a replacement for CT. In conclusion, in patients with suspected recurrent or metastatic colorectal carcinoma, FDG-PET should be performed (1) when there is rising carcinoembryonic antigen levels in the absence of a known source, (2) to increase the specificity of structural imaging when there is an equivocal lesion, and (3) as a screening method for the entire body in the preoperative staging before curative resection of recurrent disease.
Background: The majority of patients with pancreatic cancer present with advanced disease. Systemic chemotherapy has limited impact on overall survival (OS) so that eligible patients should be selected carefully. The aim of this study was to analyze prognostic factors for survival in Turkish advanced pancreatic cancer patients who survived more than one year from the diagnosis of recurrent and/or metastatic disease and receiving gemcitabine (Gem) alone or gemcitabine plus cisplatin (GemCis). Methods: This retrospective evaluation was performed for patients who survived more than one year from the diagnosis of recurrent and/or metastatic disease and who received gemcitabine between December 2005 and August 2011. Twenty-seven potential prognostic variables were chosen for univariate and multivariate analyses to identify prognostic factors associated with survival. Results: Among the 27 variables in univariate analysis, three were identified to have prognostic significance: sex (p = 0.04), peritoneal dissemination (p =0.02) and serum creatinine level (p=0.05). Multivariate analysis by Cox proportional hazard model showed only peritoneal dissemination to be an independent prognostic factor for survival. Conclusion: In conclusion, peritoneal metastasis was identified as an important prognostic factor in metastatic pancreatic cancer patients who survived more than one year from the diagnosis of recurrent and/or metastatic disease and receiving Gem or GemCis. The findings should facilitate pretreatment prediction of survival and can be used for selecting patients for treatment.
Background: To explore mRNA expression and clinical significance of ERCC1, BRCA1, RRM1, TYMS and TUBB3 genes in tumor tissue of postoperative patients with non-small cell lung cancer (NSCLC). Materials and Methods: Sixty NSCLC patients undergoing radical operation in our hospital from Nov., 2011 to Jun., 2012 were selected. Plasmid standards of ERCC1, BRCA1, RRM1, TYMS and TUBB3 were established and standard curves were prepared by SYBR fluorescent real-time quantitative PCR analysis. Samples from tumor centers were taken to detect mRNA expression of ERCC1, BRCA1, RRM1, TYMS and TUBB3 genes in cancerous tissue during operation. The total mRNA expression quantities were compared according to different clinical characteristics. Results: The total expression quantities of 5 genotypes from high to low were ERCC1>RRM1>TUBB3>TYMS>BRCA1 in turn. By pairwise comparisons, other differences showed statistical significance (p<0.05 or p<0.01) except for TYMS and TUBB3 (p>0.05); the low expression rates from high to low were ERCC1>TYMS>TUBB3>TUBB3>RRM1>BRCA1 in turn. The expression quantities of BRCA1, RRM1 and TYMS in males, smokers and patients without adenocarcinoma were all significantly higher than that in females, non-smokers and patients with adenocarcinoma, and significant differences were present (p<0.05 or p<0.01). In terms of pathological staging, the expression quantities of BRCA1, RRM1 and TYMS in phases IIa~IIb and IIIa~IIIb had a tendency to be greater than in phases I and IV. Conclusions: Resistance to chemotherapy and sensitivity to targeted therapy differ among patients with NSCLC. Differences in gene expression in different individuals were also revealed. Only according to personalized detection results can individualized therapeutic regimens be worked out, which is a new direction for oncotherapy.
Objective: Giant invasive pituitary adenoma looks histologically benign, but these tumors have an aggressive clinical course. The authors review 10 cases and discuss the results obtained and the strategy to use for the management of giant invasive pituitary adenoma. Methods: Out of a series of 155 pituitary adenomas treated surgically between 1994 and 2002, ten patients with giant invasive pituitary adenoma were selected and their clinical problems, radiologic findings, extent and invasiveness, hormonal and histologic findings and surgical results were analyzed retrospectively. Results: There were 4 male and 6 female patients, with an average age of 47 years and an average follow-up period of 42 months. The average size of tumor was 50.7mm. These tumors revealed severe invasions into surrounding structures. 8 patients underwent transsphenoidal approach(TSA) operations, 1 patient with transcranial operation and 1 patient with combined TSA and transcranial operation. In all cases, subtotal resection was performed. The histologic findings were 2 prolactinomas and 3 hormonal non-function adenomas. The therapies administered after surgical removal consisted of conventional fractionated radiotherapy (2 patients), treatment with dopamine agonists to control hyperprolactinemia (2 patients), and treatment with hormone replacement (2 patients). Conclusion: Giant invasive pituitary adenomas are characterized by different forms of expansion and invasiveness and variable clinical problems. Because of their aggressive expansion and invasiveness, there are many different strategies which can be considered for their management. The authors obtain good results by choosing conservative surgical removal and multidisciplinary treatments with serial radiological and hormonal follow-up.

Objective: The purpose of this prospective study was to evaluate the efficacy and safety of screw fixation without bone fusion for unstable thoracolumbar and lumbar burst fracture. Methods: Nine patients younger than 40 years underwent screw fixation without bone fusion, following postural reduction using a soft roll at the involved vertebra, in cases of burst fracture. Their motor power was intact in spite of severe canal compromise. The surgical procedure included postural reduction for 3 days and screw fixations at one level above, one level below and at the fractured level itself. The patients underwent removal of implants 12 months after the initial operation, due to possibility of implant failure. Imaging and clinical findings, including canal encroachment, vertebral height, clinical outcome, and complications were analyzed. Results: Prior to surgery, the mean pain score (visual analogue scale) was 8.2, which decreased to 2.2 at 12 months after screw fixation. None of the patients complained of worsening of pain during 6 months after implant removal. All patients were graded as having excellent or good outcomes at 6 months after implant removal. The proportion of canal compromise at the fractured level improved from 55% to 35% at 12 months after surgery. The mean preoperative vertebral height loss was 45.3%, which improved to 20.6% at 6 months after implant removal. There were no neurological deficits related to neural injury. The improved vertebral height and canal compromise were maintained at 6 months after implant removal. Conclusion: Short segment pedicle screw fixation, including fractured level itself, without bone fusion following postural reduction can be an effective and safe operative technique in the management of selected young patients suffering from unstable burst fracture.
Objective : We evaluated the validity of bone cement-augmented percutaneous screw fixation for treating malignant spinal metastases. Methods : Between 2011 and 2015, 14 patients (eight men and six women) who underwent bone cement-augmented percutaneous screw fixation for malignant spinal metastases were enrolled in this study. Their life expectancy was considered to be more than one month and less than one year, based on the revised Tokuhashi scoring system. Clinical findings including the back pain scale score, functional outcome, procedure related complications, and survival were assessed preoperatively, postoperatively, and then six months after the procedure. Results : Twelve of the patients (86%) survived up to six months after the procedure. Three required mini-open decompressive laminectomy for severe epidural compression. Bone cement-augmented percutaneous screw fixation was performed one level above, one level below, and at the pathologic level itself. The mean operation time was 60 minutes (45-180) and blood loss was less than 100 mL. Prior to surgery, the mean pain score on the visual analogue scale was 8.8, while one month after the procedure, it had reduced to 3.0; this improvement was maintained until the six-month assessment in the surviving patients. All patients were able to sit within the first two days after surgery, and no patient experienced neurological deterioration at the one-month follow up after the surgery. No patient experienced screw loosening during the six months of follow-up. Asymptomatic cement leakage into the epidural space was observed in two patients, but no major complications were observed. Conclusion : For selected patients with malignant spinal metastases, bone cement-augmented percutaneous screw fixation can provide significant pain relief and improve quality of life.
The purpose of this study was to elucidate the effects of music therapy on the preoperative anxiety of surgerial patients. The research design was a nonequivalent control, group non-synch-ronized design. The data were collected during the period from January 4 to March 17, 1999 at C-University hospital in Seoul. The subjects were sixty patients who had surgery under general anesthesia and had undergone laparotomy. They were assigned to two groups, thirty to the experimental group and thirty to the control group. They also did not have any complication, were alert enough to be interviewed and agreed willingly to participate in this study. The tool of Trait Anxiety Inventory was used to measure trait-anxiety on all patients and the Visual Analogue Scale(VAS) was used to measure state-anxiety on all patients. And systolic and diastolic blood pressure, pulse rate, and blood sugar levels were collected a the day before surgery and the preoperative period. The experimental group received music therapy with self-selected music tapes after choosing from a Music Preference Questionnaire, while the control group didn't receive music therapy. Data were analyzed by ${\chi}^2$-test, t-test, paired t-test. The results of this study are summarized as follows: 1. The preoperative state anxiety of the experimental group was re-markably lower than that of the control group. 2. Decreasing rate in the vital signs of the experimental group was remarkably lower than that of the control group. 3. The preoperative blood sugar of the experimental group was remarkably lower than that of the control group. According to these results, Music Therapy can be regarded as an effective nursing intervention that relieves preoperative anxiety of surgical patients and helper stabilize vital signs. From this study, the following recommendations can be made: 1. In order to decrease surgical patient's preoperative anxiety, I suggest the nursing intervention should go side by side with music therapy.
The purpose of this study was to examine the effects of hand massage as a nursing intervention on the anxiety of the hysterectomy patients in immediately prior to surgery. The method of this study was Nonequivalent Control Group Non-Synchronized Design. The data were selected from at K university hospital in Pusan, and they consisted of Experimental group-25 patients, Control group -24 patients. The data were collected from Jan. 4 to Jan. 30 in 1999. The subjects′ self-reports of anxiety (measured by the Spielberger Trait-State anxiety Inventory and Visual Analogue Scale developed by Cline et al.) were recorded before and immediately after the intervention. The objective physiologic measures of blood pressure and pulse rate. The collected data were analysed by means of frequency, percentage, standard deviation, chi- square test, t-test, ANCOVA with SPSS program. The results of this study were as following; 1. Hypothesis 1: The 1st hypothesis that "There will be significant difference of the state anxiety level just before surgery in the experimental group and control group" was supported(P= .000). 2. Hypothesis 2: The 2nd hypothesis that "There will be significant difference of the visual analogue scale score just before surgery in the experimental group and control group"was supported(P= .000). 3. Hypothesis 3: The 3rd hypothesis that "There will be significant difference of the systolic and diastolic blood pressure level just before surgery in the experimental group and control group"was supported (P= .003, P= .041). 4. Hypothesis 4: The 4th hypothesis that "There will be significant difference of the pulse rate just before surgery in the experimental group and control group"was supported(P= .004). In conclusion, hand massage is a benefical nursing intervention that alleviates the psychological, physiological anxiety of the hysterectomy patients in immediately prior to surgery. therefore it is recomended to use the hand massage as a nursing intervention for patients undergoing anxiety. The results of this study appear promising, additional research is recomended to further the appropriate uses of hand massage in nursing practice for this and other patient population.

Introduction: The characteristics of oral tongue squamous cell carcinomas (SCC) and the treatment results were reviewed to determine the appropriate treatment strategies. Materials and Methods: The medical records of 140 patients diagnosed and treated for oral tongue SCC at Yonsei University Health System from January 1995 to December 2004 were reviewed. For statistic analysis, the survival rate was determined using the Kaplan-Meier method with SPSS version 12.0, and the difference in survival rates was evaluated using a log-rank test. Results: The mean age of the patients with oral tongue SCC patients was 55 (19-85 years old). According to the T, N and pathologic stage, the patients were distributed from a higher to a lower incidence of cases, as follows: T2 (46.4%), T1 (37.9%), T4 (8.5%), and T3 (7.1%); N0 (65%), N1 (20.7%), N2 (13.6%), and N3 (0.7%); and stage I (31.4%), stage II(25.7%), stage IV (22.2%), and stage III (20.7%). Local and regional recurrence and distant metastasis was present in 13.6%, 5% and 4.2% of patients, respectively. The five-year survival rate was 72.2%, and the prognostic factors for oral tongue SCC included neck metastasis, pathologic stage of the disease, cell differentiation, treatment modality, neck dissection as part of the treatment plan, and neck node recurrence. Discussion: It is suggested that ipsilateral neck dissection or bilateral neck dissection should be selected as a treatment of tongue SCC patients with advanced stage.

Objectives: The purpose of this study is to find out the relationship between lumbar lordotic angle and low back pain patterns. Methods: We randomly selected the 1191 patients (595 males, 596 females) who have visited Bu-Chun Jaseng Hospital of Korean Medicine with low back pain. We have taken lumbar x-ray films and measured their lumbar lordotic angle, the angle formed between L1 superior margin and S1 superior margin. We investigated 1191 patients' low back pain patterns(date of occurence, existence of radiating pain, trend of increasing pain with lumbar extention and flexion, trend of increasing pain with standing and sitting positions) and analysed the relationship between lumbar lordotic angle and low back pain patterns. Results: 1. The lumbar lordotic angle of the acute phase patient is more straight than the chronic one. 2. The lumbar lordotic angle of the patients with radiating pain is more straight than the patients without radiating pain. 3. At acute phase, the lumbar lordotic angle of the patients with increasing pain from lumbar extention is more straight than those with increasing pain from lumbar flexion. 4. At chronic phase, the lumbar lordotic angle of the patients with increasing pain from lumbar flexion is more straight than those with increasing pain from lumbar extention. Conclusions: There was a significant correlation between lumbar lordotic angle and low back pain.
