Introduction
The aim of study is comparing the haemostatic properties of conventional monopolar resection (TURP) and bipolar transurethral resection in saline (TURIS) of the prostate in patients under chronic oral anticoagulants.Material and methods
Out of a cohort group of 550 endoscopic resections for bladder outlet obstruction, 176 patients on chronic oral anticoagulant therapy required endoscopic resection either by monopolar TURP or bipolar TURIS technology. Changes in haemoglobin, blood transfusion, and clot retention were compared between both groups.Results
Mean postoperative change in haemoglobin level was –1.21 ±0.92 mg/dl in the TURP group compared to –1.29 ±0.99 mg/dl in the TURIS group (p = 0.603). The need for blood transfusions and the mean numbers of units transfused did not significantly differ between the 2 groups. Clot retention appeared in 12 patients (15%) in the TURP group compared to 13 patients (13%) in the TURIS group (p = 0.828).Conclusions
Despite promising experimental results of better haemostasis and deeper coagulation depth, bipolar technology does not permit one to reduce the amount of blood loss when compared to patients treated by conventional monopolar technology in this study group of patients on oral anticoagulation therapy. Patients on oral anticoagulants suffer more incidents of clot retention, which sometimes results in re-hospitalisation. 相似文献2.
Purpose
To report the 5-year follow-up results of a randomized controlled trial comparing bipolar transurethral resection of the prostate (TURP) with standard monopolar TURP for the treatment of benign prostatic obstruction (BPO).Materials and Methods
A total of 220 patients were randomized to bipolar plasmakinetic TURP (PK-TURP) or monopolar TURP (M-TURP). Catheterization time was the primary endpoint of this study. Secondary outcomes included operation time, hospital stay, as well as decline in postoperative serum sodium and hemoglobin levels. All patients were assessed preoperatively and followed-up at 1, 6, 12, 24, 36, 48, and 60 months postoperatively. Parameters assessed included quality of life, transrectal ultrasound, serum prostate-specific antigen level, postvoid residual urine volume, maximum urinary flow rates (Qmax), and International Prostate Symptom Score. Patient baseline characteristics, perioperative data including complications, and postoperative outcomes were compared. Complication occurrence was graded according to the modified Clavien classification system.Results
PK-TURP was significantly superior to M-TURP in terms of operation time, intraoperative irrigation volume, resected tissue weight, decreases in hemoglobin and sodium, postoperative irrigation volume and time, catheterization time, and hospital stay. At 5 years postoperatively, efficacy was comparable between arms. No differences were detected in safety outcomes except that the clot retention rate was significantly greater after M-TURP.Conclusion
Our results indicate that PK-TURP is equally as effective in the treatment of BPO, but has a more favorable safety profile in comparison to M-TURP. The clinical efficacy of PK-TURP is long-lasting and comparable with M-TURP. 相似文献3.
Purpose
To determine the added value of dynamic subtraction magnetic resonance (MR) imaging for the localization of prostate cancer.Materials and Methods
We examined 21 consecutive patients who underwent MR imaging in 3T unit with a phased-array body coil and then had radical prostatectomy. After T2-weighted fast spin-echo imaging, we performed a contrast-enhanced dynamic 3D gradient-echo imaging consisting of pre-contrast, 2 successive early-phased (first imaging was started just after the appearance of contrast material in the aortic bifurcation followed by second imaging 35 seconds after the initiation of first imaging) and one 5-minute delayed post-contrast series. Subtraction of pre-contrast images from corresponding post-contrast images of each phase was performed on the console.Results
On ROC analysis, the overall accuracy (Az value) of dynamic imaging combined with subtraction imaging was higher than T2-weighted imaging (p = 0.001) or conventional dynamic imaging alone (p = 0.074) for localization of cancer foci regardless of their zonal locations. Among pathologically verified 81 lesions, the mean volume of detected lesions with the subtraction images (n = 49, 0.69 cm3) was smaller than with T2-weighted images (n = 14, 1.05 cm3) or conventional dynamic images (n = 43, 0.71 cm3).Conclusion
For localization of small prostate cancer, additional subtraction for the dynamic imaging could be superior to both T2-weighted imaging and un-subtracted dynamic imaging. 相似文献4.

Purpose
To evaluate the effectiveness of digital rectal-compression immediately after transrectal prostate biopsy (P-bx) for improving the accuracy of prostate cancer (PCa) staging.Materials and Methods
Between July 2008 and June 2010, 94 consecutive patients who had a radical prostatectomy were included in our retrospective analysis. The exclusion criteria included a history of previous P-bx and surgery, a biopsy performed in another hospital, a number of biopsy cores different from 12, or a condition interfering with bleeding assessment. The subjects were divided into two groups, compression and non-compression. All enrolled patients took magnetic resonance imaging (MRI) for PCa staging.Results
The compression and non-compression groups were comparable with respect to several baseline characteristics. However, the total hemorrhage score of intraprostatic bleeding was significantly different between the groups, even with adjustment for the time from biopsy to MRI (compression:15.4±2.32, non-compression: 24.9±2.43, p<0.001). The intra-prostatic cancer location matching rate was higher in the compression group (78.0%) than in the non-compression group (70.2%) (p=0.011). Overall accuracy of staging in compression and non-compression groups was 84.7% and 77.3%, respectively.Conclusion
Our results demonstrate that digital rectal compression performed immediately after prostate biopsy to reduce intraprostatic hemorrhage improves the accuracy for detection of PCa using MRI. 相似文献5.
Objectives
To determine the relative frequency of prostate cancer among surgical specimens, and among prostate specimens received at the pathology department ,University Hospital Calabar.Methods
Histology records were reviewed for the following: total number of histology specimens received; total number of prostate specimens; total number of prostate cancer; and the total number of cancers in males during the study period. Histology sections 4–5microns thick were cut from paraffin blocks and stained by Haematoxylin and Eosin (H&E). Histopathologic specimens were classified using the grading system of tumour differentiation described by Gleason and associates.Results
One hundred and twenty three cancers of the prostate were received, constituting 2% of the total surgical specimens and 31% of prostate specimens. Thirty three cases (27%) could not be analyzed; therefore the study is based on 90 prostate cancer specimens. Eighty nine (99%) cases were epithelial tumours (adenocarcinoma.) There was a single mesenchymal tumour (rhabdomyosarcoma) (1%). The commonest grade in this study was the high grade (Gleason grade IV).Conclusions
We observed that prostate cancer is a common among males (all sites) diagnosed at the University Hospital Calabar, with a peak incidence between the ages of 61 – 70 years (seventh decade). 相似文献6.
Background:
There is limited information on population-based cancer survival data in Latin America.Objetive:
To obtain estimates of survival for some cancers recognized as a public health priority in Colombia using data from the Cancer Registry of Cali for 1995-2004.Methods:
All cancer cases for residents of Cali were included for the following sites: breast (3,984), cervix uteri (2,469), prostate (3,999), stomach (3,442) and lung (2,170). Five-year relative survival estimates were calculated using the approach described by Estève.Results:
Five-year relative survival was 79% in patients with prostate cancer and 68% and 60% in women with breast or cervix uteri cancer, respectively. The cure fraction was close to zero in subjects with lung cancer and less than 10% in those with stomach cancer. The probability of dying from breast or prostate cancer in people in the lower socio-economic strata (SES) was 1.8 and 2.6 times, respectively, when compared to upper SES, p <0.001. Excess mortality associated with cancer was independent of age in prostate or breast cancer. After adjusting for age, sex and SES, the risk of dying from breast, cervix uteri, prostate and lung cancer during the 2000-2004 period decreased 19%, 13%, 48% and 16%, respectively, when compared with the period of 1995-1999. There was no change in the prognosis for patients with stomach cancer.Conclusions:
Survival for some kinds of cancer improved through the 1995-2004 period, however health care programs for cancer patients in Cali are inequitable. People from lower SES are the most vulnerable and the least likely to survive. 相似文献7.

Introduction
The aim of the study was to evaluate the expression of CtBP2 in prostate cancer and to determine its relationship with clinicopathologic parameters.Material and methods
The expression of CtBP2 in 119 prostate cancer tissues and 41 normal tissues was examined by qPCR and Western blot analysis, and the results were correlated with clinicopathologic parameters.Results
CtBP2 expression in prostate cancer tissues was higher than that in normal samples. CtBP2 overexpression was closely correlated with serum prostatic specific antigen (PSA) (p = 0.018), advanced tumor stage (T3) (p = 0.025), higher Gleason scores (p = 0.019), positive extraprostatic extension (p = 0.012), positive vascular invasion (p = 0.011) and perineural invasion (p = 0.035). However, no significant association was found between CtBP2 abnormal expression and other parameters, including age (p = 0.776), positive lymph node (p = 0.872) and positive surgical margin (p = 0.37). Moreover, CtBP2 overexpression was significantly associated with poor clinical outcome of prostate cancer (p = 0.0168).Conclusions
CtBP2 is overexpressed in prostate cancer, and its increased expression is closely associated with tumor progression and the outcome of prostate cancer. 相似文献8.

Purpose
These are the clinical experiences of Korean incidental prostate cancer patients detected by transurethral resection of the prostate according to initial treatment: active surveillance (AS), radical prostatectomy (RP) and hormone therapy (HT).Materials and Methods
We retrospectively reviewed the records of 156 incidental prostate cancer patients between 2001 and 2012. The clinicopathologic outcomes were reviewed and follow-up results were obtained.Results
Among 156 patients, 97 (62.2%) had T1a and 59 (37.8%) had T1b. Forty-six (29.5%) received AS, 67 (42.9%) underwent RP, 34 (21.8%) received HT, 4 (2.6%) received radiotherapy, and 5 (3.2%) chose watchful waiting. Of 46 patients on AS, prostate-specific antigen (PSA) progression occurred in 12 (26.1%) patients. Among them, 3 patients refused treatment despite PSA progression. Five patients, who underwent RP as an intervention, all had organ-confined Gleason score ≤6 disease. In 67 patients who underwent RP, 50 (74.6%) patients had insignificant prostate cancer and 8 (11.9%) patients showed unfavorable features. During follow-up, biochemical recurrence occurred in 2 patients. Among 34 patients who received HT, 3 (8.8%) patients had PSA progression. Among 156 patients, 6 patients died due to other causes during follow-up. There were no patients who died due to prostate cancer.Conclusion
The clinical outcomes of incidental prostate cancer were satisfactory regardless of the initial treatment. However, according to recent researches and guidelines, immediate definite therapy should be avoided without a careful assessment. We also believe that improved clinical staging is needed for these patients. 相似文献9.
Objective
The cytochrome P450 17α-hydroxylase (CYP17) plays a vital role in androgen biosynthesis. A T-to-C polymorphism in the 5′ promoter region of CYP17 has been implicated as a risk factor for prostate cancer, but the results of individual studies are inconclusive or controversial. To derive a more precise estimation of the relationship, we performed an updated meta-analysis from 31 studies based on 27 publications.Methods
A comprehensive search was conducted to examine all the eligible studies of CYP17 polymorphism and prostate cancer risk. We used odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of the association.Results
Overall, individuals with CC/CT genotype were not associated with prostate cancer risk (CC vs. TT: OR = 1.03, 95% CI = 0.86-1.24, P = 0.72, Pheterogeneity < 0.0001; CT vs. TT: OR = 0.99, 95% CI = 0.87-1.12, P = 0.88, Pheterogeneity = 0.0006). In the stratified analysis by ethnicity, there was a significantly increased risk of prostate cancer among individuals of African descent under the recessive model (OR = 1.56, 95% CI = 1.01-2.39, P = 0.04, Pheterogeneity = 0.65).Conclusion
This meta-analysis suggested that CYP17 polymorphism might be associated with prostate cancer risk among individuals of African descent. 相似文献10.

Objective
The association between ribonuclease L (RNASEL) gene polymorphisms and prostate cancer risk has been widely reported, but the results of these studies remained controversial and underpowered. We performed a meta-analysis of 28 studies to evaluate the association between Arg462Gln and Asp541Glu polymorphisms in the RNASEL gene and prostate cancer risk.Methods
Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated to assess the association between RNASEL polymorphisms and prostate cancer risk.Results
A significantly increased prostate cancer risk was found for the Arg462Gln polymorphism in Africans (Gln/Gln vs Arg/Arg: OR = 2.50, 95%CI = 1.28-4.87; Gln/Gln vs Gln/Arg + Arg/Arg: OR = 2.54, 95%CI = 1.30-4.95), but not in Europeans and Asians. Additionally, the Asp541Glu polymorphism was associated with increased total prostate cancer risk (Glu-allele vs Asp-allele: OR = 1.04, 95%CI = 1.01-1.07; Glu/Glu vs Asp/Asp: OR = 1.22, 95%CI = 1.03-1.46; Glu/Glu vs Glu/Asp + Asp/Asp: OR = 1.09, 95%CI = 1.02-1.16). In the stratified analysis for the Asp541Glu polymorphism, there was a significantly increased prostate cancer risk in Africans and Europeans, and in hospital-based prostate cancer cases.Conclusion
The meta-analysis results showed evidence that RNASEL Arg462Gln and Asp541Glu polymorphisms are associated with prostate cancer risk and could be low-penetrance prostate cancer susceptibility biomarkers. 相似文献11.

Introduction
The aim was to examine the effect of a sedative or analgesic supplement to periprostatic nerve blockage (PNB) on pain reduction during probe insertion and needle penetration in patients undergoing transrectal ultrasound (TRUS)-guided prostate biopsy. We also investigated the effects of this procedure on the positive response rate in re-biopsy.Material and methods
One hundred TRUS-guided prostate biopsy patients due to prostate-specific antigen (PSA) levels higher than 2.5 ng/ml and/or abnormal rectal examination findings were evaluated. Group 1 (PNB) was given periprostatic lidocaine injection before the procedure. Group 2 (analgesic) was given tramadol and PNB. Group 3 (sedative) was given midazolam and PNB. Group 4 (control) was not given any anaesthesia or analgesics. Pain scores were assessed during probe insertion and needle penetration by a visual analogue scale.Results
During probe insertion, the mean pain score of the sedative group was lower than that of the control, analgesic and PNB groups (p < 0.001, p = 0.009, and p < 0.001, respectively). During needle penetration, the mean pain score of the control group was higher than that of the other groups (p < 0.001). The rate of positive response to re-biopsy was found to be 56% in the control group and between 92% and 100% in the other three groups (p < 0.001).Conclusion
According to our results, it can be concluded that midazolam, given supplementary to PNB, contributes as an effective and safe alternative for pain control during both probe insertion and penetration of the biopsy needle into the prostate capsule; however, tramadol supplement does not provide any additional contributions. 相似文献12.

Purpose
Liver resection with colorectal liver metastasis widely accepted and has been considered safe and effective therapeutic option. However, the role of liver resection in breast cancer with liver metastasis is still controversial. Therefore, we reviewed the outcome of liver resection in breast cancer patients with liver metastases in a single hospital experiences.Materials and Methods
Between January 1991 and December 2006, 2176 patients underwent breast cancer surgery in Gangnam Severance Hospital. Among these patients, 110 cases of liver metastases were observed during follow-up and 13 of these patients received liver resection with potential feasibility to achieve an R0 resection.Results
The median time interval between initial breast cancer and detection of liver metastasis was 62.5 months (range, 13-121 months). The 1-year and 3-year overall survival rates of the 13 patients with liver resection were 83.1% and 49.2%, respectively. The 1-year and 3-year overall survival rates of patients without extrahepatic metastasis were 83.3% and 66.7% and those of patients with extrahepatic metastasis were 80.0% and 0.0%, respectively (p=0.001).Conclusion
Liver resection for metastatic breast cancer results in improved patient survival, particularly in patients with solitary liver metastasis and good general condition. 相似文献13.

Introduction
The aim of the present study was to analyse patients’ knowledge in the field of neoplastic prophylaxis.Material and methods
The research was carried out between 2007 and 2008 in the Provincial Hospital in Bydgoszcz (i.e. general surgery, gynaecology and obstetrics, urology, breast surgery and thoracic surgery). Altogether 300 patients (of whom 250 were hospitalized) as well as 50 healthy subjects forming the control group were invited to participate in the study. A proprietary questionnaire containing eight multiple choice and another twelve open-ended questions was used for the purpose of the study.Results
Prostate and lung cancer patients were more aware of their diseases compared to the control group, but the differences were not significant (p = 0.85 and p = 0.53 respectively). In the field of screening the patients’ knowledge, it was significantly higher in breast cancer subjects (p = 0.0008) while there was no difference compared to the control group in the remaining groups of cancer patients (i.e. colorectal, prostate or uterus cancer). Those most aware of their condition were patients from small towns (below 50,000), while subjects living in villages were the least aware.Conclusions
Patients showed the greatest amount of knowledge regarding breast cancer and the least amount regarding prostate cancer. Oncological awareness in cancer patients was found to be related to variables such as education, age and residence. No difference was found between patients and controls, comparing their knowledge of disease symptoms as well as screening possibilities. 相似文献14.

Purpose
Endoscopic papillectomy (EP) is currently employed for the treatment of ampullary adenoma. This study aimed to evaluate the clinical, endoscopic, and histologic characteristics related to complications and long-term outcomes of EP.Materials and Methods
Thirty-nine patients underwent EP for ampullary adenoma. Patients were grouped according to the occurrence of procedure-related complications: no complication group (n=28) and complication group (n=11).Results
The overall complication rate was 28.2%. The most common complication was EP-related pancreatitis (n=7). Amylase (p=0.006) and lipase levels (p=0.007), 24 hours after EP, were significantly higher in the complication group, however, these levels did not differ at earlier times. As the tumor progressed from adenoma to cancer, the complete resection was significantly lessened (p=0.032). The duration of antiprotease injection during the hospital stay was significantly longer (p=0.017) and the transfusion requirements were significantly higher (p=0.018) in the complication group. During a median follow-up of 15 months, three lesions (10.3%) recurred among patients with complete resection (n=29) and five lesions (12.8%) recurred among enrolled patients. One patient with progressive recurrence from low-grade dysplasia to adenocarcinoma was noted during a follow-up of 22 months.Conclusion
If symptoms are present, amylase and lipase levels, 24 hours after EP, could help predict possible EP-related pancreatitis. Histologic diagnosis through resected specimens may result in complete resection. Patients with complications need a longer duration of antiprotease injection during their hospital stay and more transfusions. The recurrence rate was not significantly high in completely resected cases, however, there was a possibility of progressive recurrence. 相似文献15.

Background
Benign diseases of the prostate are common in the general male population, and prostate cancer is the most common cancer in men. Uncertaintyastothe nature of the association between benign and malignant disease is a source of concern for patients and clinicians.Aim
To determine the likelihood of men with benign prostate disease developing prostate cancer compared with men without disease.Design
Incident matched case-control studyMethod
All incident cases of prostate cancer (n = 984) were identified in a nationally representative community-based population, and each was matched by age with two controls with no prostate cancer (n = 1968). Participants'' records of the previous 5 years were searched for diagnoses of benign prostate disease. Analyses investigated an a priori hypothesis that clinicians may record disease as benign until proven to be malignant, causing misleading significant associations between benign and malignant diagnoses.Results
There was a significant association between a diagnosis of prostate cancer and a benign diagnosis at any time in the previous 5 years: odds ratio (OR) 1.57 (95% confidence interval [CI] = 1.32 to 1.88). However, there was no significant association when benign diagnoses within 6 months and within 12 months of cancer diagnoses were excluded: OR 1.19 (95% CI = 0.97 to 1.46) and OR 1.00 (95% CI = 0.79 to 1.27) respectively.Conclusion
Findings from this study suggest that unless prostate cancer is detected within 6 months, men diagnosed for the first time with benign disease are at no greater risk of prostate cancer than those with no recorded prostate disease. 相似文献16.

Background
Currently, there is no standardised screening for prostate cancer in Europe. Assessment of risk is opportunistically undertaken in consultation with the GP or urologist. Evaluation of the prostate gland consists of a prostate-specific antigen (PSA) serum level and a digital rectal examination (DRE) of the gland. DRE is an essential part of the assessment that can independently predict prostate cancer in the setting of a normal PSA level.Aim
To evaluate the clinical usefulness of the DRE in general practice and urology clinics, and to ascertain its positive predictive value and sensitivity.Design and setting
A retrospective analysis study of a cohort of Irish men who underwent TRUS guided biopsy of the prostate in a single Irish tertiary referral centre, despite a normal PSA level. Patients were identified from a Rapid Access Prostate Clinic patient database. Pathological biopsy results were correlated with clinical DRE findings.Method
Patient demographics, PSA levels, and DRE findings from a prospectively established database and hospital data systems from May 2009 to October 2013 were analysed.Results
Of 103 men referred over a 53-month period with a normal age-adjusted PSA level, 67% were referred on the basis of an abnormal DRE alone. Thirty-five per cent of males with a normal PSA had prostate cancer. DRE alone had a sensitivity and specificity of 81% and 40% respectively in diagnosing prostate cancer, with a positive predictive value of 42%. Seventy-six per cent of these men had high-grade disease.Conclusion
DRE is a key part of the assessment for prostate cancer. It can independently identify patients at risk of prostate cancer, with a substantial proportion of these having clinically significant disease requiring treatment. This study reinforces the importance of DRE in the primary care setting in the assessment for prostate cancer. An abnormal DRE, even in the setting of a normal PSA level, necessitates referral. 相似文献17.

Purpose
The aim of this study was to evaluate the recent changes in the clinicopathologic features of prostate cancer in Korea and to compare these features with those of Western populations.Materials and Methods
We retrospectively reviewed the data of 1582 men undergoing radical prostatectomy for clinically localized prostate cancer between 1995 and 2007 at 10 institutions in Korea for comparison with Western studies. The patients were divided into two groups in order to evaluate the recent clinicopathological changes in prostate cancer: Group 1 had surgery between 1995 and 2003 (n=280) and Group 2 had surgery between 2004 and 2007 (n=1302). The mean follow-up period was 24 months.Results
Group 1 had a higher prostate-specific antigen level than Group 2 (10.0 ng/mL vs. 7.5 ng/mL, respectively; p<0.001) and a lower proportion of biopsy Gleason scores ≤6 (35.0% vs. 48.1%, respectively; p<0.001). The proportion of patients with clinical T1 stage was higher in Group 2 than in Group 1. Group 1 had a lower proportion of organ-confined disease (59.6% vs. 68.6%; p<0.001) and a lower proportion of Gleason scores ≤6 (21.3% vs. 33.0%; p<0.001), compared to Group 2. However, the relatively higher proportion of pathologic Gleason scores ≤6 in Group 2 was still lower than those of Western men, even though the proportion of organ-confined disease reached to that of Western series.Conclusion
Korean men with prostate cancer currently present better clinicopathologic parameters. However, in comparison, Korean men still show relatively worse pathologic Gleason scores than Western men. 相似文献18.

INTRODUCTION
Testosterone is needed for normal male development, muscle strength, bone mineralization, hematopoietic function, and sexual and reproductive functions. The main purpose of androgen deprivation therapy in prostate cancer is to reduce tumor progression, but therapy is often accompanied by significant adverse effects.OBJECTIVE
This study aimed to determine the effects of androgen deprivation therapy on body composition and resting metabolic rate in patients with prostate cancer.PATIENTS AND METHODS
A prospective study was performed to evaluate the body composition of 16 elderly males (aged 63–96; median age 71) with prostate cancer scheduled for orchiectomy, one year before and after surgery. Body composition was measured by DEXA, and energy expenditure, fat and carbohydrate oxidation were measured by indirect calorimetry.RESULTS
Body weight (p=0.01), lean mass (p=0.004), and lipid oxidation (p=0.001) decreased significantly. Carbohydrate oxidation (p=0.02), FSH (p=0.0001) and LH (p=0.0001) levels increased significantly. Changes in fat mass (p=0.06) and bone mineral density (p=0.48) were not significant.CONCLUSIONS
After 12 months of androgen deprivation therapy, elderly men with metastatic prostate cancer exhibit a decline in lean body mass and lipid oxidation, together with increased carbohydrate oxidation. 相似文献19.

Purpose
Circumferential resection margin (CRM) involvement is a well-known predictor for poor prognosis in rectal cancer. However, the significance is controversial in some studies. Accordingly, this study attempted to examine the prognostic impact of CRM involvement in stage III rectal cancer.Materials and Methods
Between January 1990 and December 2007, a total of 449 patients who underwent curative resection followed by complete adjuvant chemoradiotherapy for stage III rectal cancer located within 12 cm from the anal verge were selected. Patients were divided into a CRM-positive group (n=79, 17.6%) and a CRM-negative group (n=370, 82.4%).Results
With a median follow-up of 56.6 months, recurrent disease was seen in 53.2 and 43.5% of the CRM-positive and CRM-negative group, respectively. CRM involvement was an independent prognostic factor for 5-year systemic recurrence-free survival (HR: 1.5, CI: 1.0-2.2, p=0.017). However, no significant difference was observed for local recurrence rate between the two groups (13.0 and 13.5%, respectively, p=0.677).Conclusion
In this study, local recurrence rate did not differ according to CRM involvement status in stage III rectal cancer patients, although CRM involvement was shown to be an independent poor prognostic factor. Accordingly, validation of the results of this study by further large prospective randomized trials is warranted. 相似文献20.
