Abstract
PURPOSE To assess the change in subfoveal choroidal thickness (SFCT) in central serous chorioretinopathy (CSC) following spontaneous resolution and low-fluence photodynamic therapy (PDT) using the enhanced depth imaging optical coherence tomography (EDI-OCT). METHODS A total of 36 consecutive eyes of 36 patients were included in this retrospective study: 16 eyes with spontaneously resolved CSC and 20 eyes with PDT-treated CSC. Best-corrected visual acuity and SFCT were evaluated at each visit until complete absorption of the subretinal fluid. SFCT of 32 normal subjects were also measured, as the control group. Wilcoxon's singed-rank test was used to evaluate the effects of spontaneous resolution and PDT. To compare the SFCT of the eyes with resolved CSC with that of the normal eyes, Mann-Whitney U-test with Bonferroni correction was also employed. RESULTS SFCT of patients was 459.16±77.50 μm at the baseline, and decreased to 419.31±54.49μm after a spontaneous resolution (P=0.015). However, SFCT was not normalized in comparison with that of the normal subjects (P<0.001). SFCT in PDT group was also reduced from 416.43±74.01 to 349.50±88.99 μm (P<0.001), with no significant difference with the normal value (P=0.087). CONCLUSIONS SFCT in patients with CSC decreased both after spontaneous resolution and low-fluence PDT. However, only in the PDT group, after disappearance of subretinal fluid, did it decrease to that of normal subjects.

Abstract
BACKGROUND Biological complexity leads to significant variation in the survival of patients with stage I non-small-cell lung cancer (NSCLC). DNA damage response (DDR) pathways play a critical role in maintaining genomic stability and in the progression of NSCLC. Therefore, the development of a prognostic biomarker focusing on DDR pathways is an intriguing issue. PATIENTS AND METHODS Expression of several proteins (ATM, ATMpS1981, γH2AX, 53BP1, 53BP1pS25, Chk2, Chk2pT68, MDC1, MDC1pS964, BRCA1pS1423, and ERCC1) and overall survival were investigated in 889 pathological stage I NSCLC patients. RESULTS Low expression of BRCA1pS1423 or ERCC1 was significantly associated with worse survival in the whole cohort of patients. Analysis performed based on histology revealed that low expression of γH2AX, Chk2pT68, or ERCC1 was a poor prognostic factor in squamous cell carcinoma patients [adjusted hazard ratio (aHR), Cox P: 1.544, 0.012 for γH2AX; 1.624, 0.010 for Chk2pT68; 1.569, 0.011 for ERCC1]. The analysis of the interaction between two proteins showed that this effect was more pronounced in squamous cell carcinoma patients. However, these effects were not detected in adenocarcinoma patients. CONCLUSIONS The proteins involved in DDR pathways exhibited differential expression between squamous cell carcinoma and adenocarcinoma and were important determinants of survival in stage I squamous cell carcinoma patients.

Abstract
BACKGROUND AND AIMS CpG islands of the promoter region of some genes are methylated in pancreatic cancer tissue and the detection of this methylation has been suggested to be useful in the diagnosis of various cancers. The aim of this study was to investigate whether the detection of methylated CpG islands in plasma can be used in the diagnosis of pancreatic cancer. MATERIAL AND METHODS Plasma DNA was collected from patients with pancreatic cancer, chronic pancreatitis, and healthy controls. The methylation status of six genes, UCHL1, NPTX2, SARP2, ppENK, p16, and RASSF1A, was checked by methylation-specific PCR and was subsequently confirmed by direct sequencing after bisulfite treatment. RESULTS CpG island methylation was detectable in 13 of 16 patients (81.3%) with pancreatic cancer, 1 of 29 healthy controls (3.5%), and 8 of 13 patients with chronic pancreatitis (61.5%). The mean number of genes with CpG island methylation was 1.6±1.2 in pancreatic cancer, 0.04±0.19 in healthy controls, and 1.2±1.1 in chronic pancreatitis. Among six genes, p16 was more specifically methylated in pancreatic cancer compared with chronic pancreatitis (p=0.016). The methylation status was not correlated with smoking history, tumor size, or cancer stage. CONCLUSIONS The detection of methylated genes in the plasma may have a role in differentiating between pancreatic cancers and healthy controls but not between pancreatic cancer and chronic pancreatitis.

Abstract
We performed a prospective study to examine the influence of the patient’s position on the location of the abdominal organs, to investigate the possibility of a true lateral approach for transforaminal endoscopic lumbar discectomy. Pre-operative abdominal CT scans were taken in 20 patients who underwent endoscopic lumbar discectomy. Axial images in parallel planes of each intervertebral disc from L1 to L5 were achieved in both supine and prone positions. The most horizontal approach angles possible to avoid injury to the abdominal organs were measured. The results demonstrated that the safe approach angles were significantly less (i.e., more horizontal) in the prone than in the supine position. Obstacles to a more lateral approach were mainly the liver, the spleen and the kidneys at L1/2 (39 of 40, 97.5%) and L2/3 (28 of 40, 70.0%), and the intestines at L3/4 (33 of 40, 82.5%) and L4/5 (30 of 30, 100%). A true lateral approach from each side was possible for 30 of the 40 discs at L3/4 (75%) and 23 of the 30 discs at L4/5 (76.7%). We concluded that a more horizontal approach for transforaminal endoscopic lumbar discectomy is possible in the prone position but not in the supine. Prone abdominal CT is more helpful in determining the trajectory of the endoscope. While a true lateral approach is feasible in many patients, our study shows it is not universally applicable.

Abstract
Esophageal leiomyoma is the most common benign tumor of the esophagus. Although enucleation via thoracotomy has been considered standard treatment, minimally invasive surgery is increasingly used for the treatment of this disease. We analyzed our surgical outcomes by comparing thoracotomy and the thoracoscopic approach. A retrospective review was performed of patients who underwent surgical resection of esophageal leiomyomas at the Seoul National University Hospital. Between 1982 and 2005, 63 patients were identified (male, n= 39; female, n= 24) at a mean age of 44.5 years. Thirty-two patients (51%) were symptomatic. Forty-five patients underwent thoracotomy, and 18 patients were resected using thoracoscopy. There was no mortality. The mean length of hospital stay was 10.3 days in the open group and 8.0 days in thoracoscopy group. Intraoperative mucosal repair was required in eight patients. Preoperative endoscopic mucosal biopsy within 1 month was identified as a risk factor for mucosal injury. Among the 11 patients with tumors less than 1.5 cm in size, thoracoscopic resection was attempted on four patients, and three out of the four cases required conversions to thoracotomy. Minimally invasive surgery for esophageal leiomyoma can be performed with good results. Our results suggest that the thoracoscopic approach should be considered as a standard surgical method for the treatment of esophageal leiomyoma. However, in cases of small tumors less than 1.5 cm in size, localization of the tumor may be difficult, and if asymptomatic, a regular monitoring should be considered as an alternative approach in such small tumors.

Abstract
The objectives of this study were to quantitatively estimate the distribution of arsenic with its speciation and to identify potential pathways for transformation of arsenic species from samples of water, sediments, and plants in the ecosystem affected by the Cheongog Spring, where As(V) concentration reached levels up to 0.270 mg L(-1). After flowing about 100 m downstream, the arsenic level showed a marked reduction to 0.044 mg L(-1) (about 84% removal) without noticeable changes in major water chemistry. The field study and laboratory hydroponic experiments with the dominant emergent plants along the creek (water dropwort and thunbergian smartweed) indicated that arsenic distribution, reduction, and speciation appear to be controlled by, (i) sorption onto stream sediments in exchangeable fractions, (ii) bioaccumulation by and possible release from emergent plants, and (iii) transformation of As(V) to As(III) and organic species through biological activities.

Abstract
PURPOSE To investigate clinicopathologic findings of patients with small cell carcinoma of the uterine cervix (SCCUC), and evaluate their prognosis. METHODS We retrospectively reviewed the medical records of 20 patients with histologically confirmed SCCUC treated between October 1996 and December 2004 at Asan Medical Center, Korea. The review included demographic data, pathologic findings, treatments, and outcomes. RESULTS Of 1,358 invasive cervical carcinoma, the incidence of SCCUC was 1.5%. Median age was 45.5 years. The clinical stages were Ib in 11, IIa in two, IIb in one, IIIa in one, IIIb in one, IVa in three and IVb in one. Fourteen patients underwent radical hysterectomy. Ten patients are alive and nine show no evidence of disease. Median overall survival was 77.0 months and 5-year overall survival rate was 50%. There was significant difference in overall survival with FIGO stage and tumor mass size. CONCLUSION Advanced FIGO stage and tumor mass size are poor prognostic factors for overall survival in patients with SCCUC. Even though SCCUC is a highly aggressive neoplasm, early diagnosis and combined therapeutic modalities may lead to longer survival in some patients.

Abstract
There has been no clear evidence demonstrating whether DNA hypermethylation can affect the prognosis of esophageal cancer. We collected tissue from 50 cases of squamous cell carcinoma of the esophagus and tested them for DNA hypermethylation using methylation-specific polymerase chain reaction. CpG island hypermethylations were observed in 10% for p16, 34% for RARbetaP2, 46% for adenomatosis polyposis coli (APC), 14% for RASSF1A, 84% for FHIT, and 8% for hMLH1. APC promoter hypermethylation was frequently found in patients without lymph node metastasis compared with those with lymph node metastasis (62.5% : 30.8%, P = 0.025). The number of metastatic lymph nodes were lower in patients with APC promoter hypermethylation (0.87 +/- 0.30 : 3.07 +/- 0.72, P = 0.008). Excluding operative mortalities and incomplete resections, 42 patients were analyzed for long-term outcome. During the mean follow-up period of 35 months, 17 developed recurrence and 14 died of cancer. Ten patients died of other causes. In univariable analysis, unmethylation of APC (P = 0.0015) and FHIT (P = 0.0044), as well as presence of lymph node metastasis (P = 0.0038), were risk factors for recurrence. In multivariable analysis, lymph nodes metastasis (P = 0.050) and unmethylation of APC promoter (P = 0.023) remained as significant risk factors. In conclusion, promoter hypermethylation of the APC gene is related to a lower number of metastatic lymph nodes and to superior prognosis in terms of recurrence, which suggests it might be involved in the process of lymph node metastasis in esophageal cancer.

Abstract
The objective of this study was to evaluate the validity and clinical impact of positron emission tomography (PET) or positron emission tomography/computed tomography (PET/CT) using 18-fluoro-2-deoxy-D-glucose in the posttherapy surveillance of patients with endometrial carcinoma. Eighty-eight patients previously treated for histopathologically diagnosed endometrial adenocarcinoma underwent 99 PET or PET/CT scans at follow-up visits at Asan Medical Center, Seoul, Korea, between 2001 and 2007. The standard of reference for tumor recurrence consisted of histopathologic confirmation or follow-up information at least 6 months after PET or PET/CT. Of the 88 patients, 24 underwent PET (n= 11) and/or PET/CT (n= 14) scans due to suspected disease recurrence. The sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of PET and/or PET/CT in detecting recurrence in these patients were 100%, 83.3%, 96%, 95%, and 100%, respectively. Especially, PET/CT revealed true-positive findings in three patients with elevated tumor markers but negative CT findings. The remaining 64 patients underwent PET (n= 8) and/or PET/CT (n= 66) as part of routine posttherapy surveillance; these patients were asymptomatic, with no evidence of disease. The sensitivity, specificity, accuracy, PPV, and NPV of PET and/or PET/CT in detecting recurrence in these patients were all 100%. Clinical decisions on treatment were changed in 14 (21.9%) patients by introducing PET or PET/CT into their conventional posttherapy surveillance program. PET and/or PET/CT were highly effective in discriminating true recurrence in patients with suspected recurrence, highly sensitive in detecting recurrence in asymptomatic patients, and had impacts on clinical decisions in a considerable portion of patients.

Abstract
The purpose of this study was to investigate the prognostic value of tumour-associated macrophages with a focus on micro-anatomical localisation and determine whether molecular changes of the epidermal growth factor receptor (EGFR) are related to macrophage infiltration in resected non-small cell lung cancer (NSCLC). One hundred and forty-four patients were included in this study. Immunohistochemistry was used to identify CD68+ macrophages in the tumour islet and surrounding stroma. Epidermal growth factor receptor mutations were studied by direct sequencing. The EGFR gene copy number and protein expression were analysed by fluorescence in situ hybridisation and immunohistochemistry. Patients with a high tumour islet macrophage density survived longer than did the patient with a low tumour islet macrophage density (5-year overall survival rate was 63.9 vs 38.9%, P=0.0002). A multivariate Cox proportional hazard analysis revealed that the tumour islet macrophage count was an independent prognostic factor for survival (hazard ratio 0.471, 95% confidence interval 0.300-0.740). However, EGFR mutations, gene copy number, and protein expression were not related to the macrophage infiltration. In conclusion, tumour islet macrophage infiltration was identified as a strong favourable independent prognostic marker for survival but not correlated with the molecular changes of the EGFR in patients with resected NSCLC.

Abstract
In spite of the clinical importance of epithelial ovarian cancer (EOC), little is known about the pathobiology of its precursor lesions and progression. Regulatory mechanisms of the cell cycle are mainly composed of cyclins, cyclin-dependent kinases (CDK), and CDK inhibitors. Alteration of these mechanisms results in uncontrolled cell proliferation, which is a distinctive feature of human cancers. This review describes the current state of knowledge about the alterations of cell-cycle regulations in the context of p16-cyclin D1-CDK4/6-pRb pathway, p21-p27-cyclin E-CDK2 pathway, p14-MDM2-p53 pathway, and ATM-Chk2-CDC25 pathway, respectively. Recent evidence suggests that ovarian cancer is a heterogenous group of neoplasms with several different histologic types, each with its own underlying molecular genetic mechanism. Therefore, expression of cell cycle regulatory proteins should be tested separately according to each histologic type. In serous ovarian carcinoma, high expression of p16, p53, and p27 and low expression of p21 and cyclin E were shown. In addition, this review focuses on the prognostic significance of cell cycle-regulating proteins in EOC. However, it is difficult to compare the results from different groups due to diverse methodologies and interpretations. Accordingly, researchers should establish standardized criteria for the interpretation of immunohistochemical results.

Abstract
The purpose of this study is to assess clinicopathologic features of pseudomyxoma peritonei (PMP) that has ovarian pathology and its relationship with the prognosis. From 1995 to 2004, the clinical records and follow-up data of 35 patients with PMP, which had primarily originated from the ovary, were collected from 11 institutes of gynecologic oncology in Korea and retrospectively analyzed. All patients had ovarian lesion histologically confirmed with PMP. The mean age at diagnosis was 53.7 years (range: 16-82 years). There were 25 (71.4%) patients with disseminated peritoneal adenomucinosis, 5 (14.3%) with peritoneal mucinous carcinomatosis with intermediate group, and 5 (14.3%) with peritoneal mucinous carcinomatosis. The clinical stages at diagnosis were IA in 2 patients, IIIB in 4, IIIC in 23, IV in 1, and unknown in 5. In preoperative tumor markers, the positive rates were 72% (CA125), 47.4% (CA19-9), and 84.6% (CEA). Thirty-four patients underwent surgical staging or cytoreduction, and then 27 patients (77%) received adjuvant chemotherapy that was given to patients in a nonuniform fashion. The 5-year survival for 35 patients was 87%. Survival rate was significantly lower in patients >50 years of age (P = 0.002). Our data showed that age of the patient is the only significant prognostic factor in PMP that has ovarian lesion.

Abstract
For the purpose of optimizing the design of the locomotion mechanism as well as the body shape of a self-propelled capsule endoscope, an analytical model for the prediction of frictional resistance of the capsule moving inside the small intestine was first developed. The model was developed by considering the contact geometry and viscoelasticity of the intestine, based on the experimental investigations on the material properties of the intestine and the friction of the capsule inside the small intestine. In order to verify the model and to investigate the distributions of various stress components applied to the capsule, finite element (FE) analyses were carried out. The comparison of the frictional resistance between the predicted and the experimental values suggested that the proposed model could predict the frictional force of the capsule with reasonable accuracy. Also, the FE analysis results of various stress components revealed the stress relaxation of the intestine and explained that such stress relaxation characteristics of the intestine resulted in lower frictional force as the speed of the capsule decreased. These results suggested that the frontal shape of the capsule was critical to the design of the capsule with desired frictional performance. It was shown that the proposed model can provide quantitative estimation of the frictional resistance of the capsule under various moving conditions inside the intestine. The model is expected to be useful in the design optimization of the capsule locomotion inside the intestine.

Abstract
Human papillomavirus (HPV) is a major causative agent of anogenital warts and a necessary cause of cervical cancer. This report will serve to assess the safety and immunogenicity of quadrivalent (types 6, 11, 16, and 18) HPV L1 virus-like particle (VLP) vaccine in the Korean population. We performed a randomized, double-blind, placebo-controlled study in 176 volunteers aged 9-23 years. Using a 2:1 ratio for randomization, 117 women were assigned to quadrivalent HPV (20 mug type 6, 40 mug type 11, 40 mug type 16, and 20 mug type 18) vaccine and 59 women to placebo. Individuals received vaccine at day 1, month 2, and month 6 and provided blood samples for analysis at enrollment at month 7. Analyses were done as specified in the study protocol. Quadrivalent HPV vaccine was generally well tolerated, with no vaccine-related serious adverse experiences. Quadrivalent HPV vaccine induced seroconversion for each vaccine-related HPV type. At month 7, vaccine-induced type-specific antibody titer was high. In conclusion, administration of quadrivalent HPV VLP vaccine to Korean women aged 9-23 years was generally well tolerated and highly immunogenic.

Abstract
OBJECTIVE To determine human leukocyte antigen (HLA)-G and interleukin (IL)-10 expression and the relationship between HLA-G expression and clinicopathologic features in patients with cervical cancer. METHOD Tissue samples were obtained from 40 patients with cervical cancer and 15 control patients with a normal cervix. Quantitative real-time RT-PCR for mRNA and western blot analysis for protein expression were used. RESULT Both HLA-G and IL-10 mRNA expression in cervical cancer tissues was significantly greater than normal controls (P<0.001, P=0.005). Protein expression of HLA-G and IL-10 in the cancer group was also significantly greater than in the controls (P<0.001, P=0.021). There was an inverse relationship between FIGO stage and HLA-G mRNA expression (P=0.046). CONCLUSION HLA-G and IL-10 might play an important role in cancer progression of the cervix. High HLA-G mRNA expression may be related to early carcinogenesis since it was associated with early-stage cervical cancer.

Abstract
Cerebellar Purkinje neurons have intracellular regulatory systems including Ca2+-binding proteins, intracellular Ca2+ stores, Ca2+-ATPase and Na+-Ca2+ exchanger (NCX) that keep intracellular Ca2+ concentration ([Ca2+]i) in physiological range. Among these, NCX interacts with AMPA receptors, activation of which induces cerebellar synaptic plasticity. And the activation of metabotropic glutamate receptor 1 (mGluR1) is also involved in the induction of cerebellar long-term depression. The interaction of NCX with mGluR1 is not known yet. Thus, in this study, the functional relationship between NCX and mGluR1 in modulating the [Ca2+]i in rat Purkinje neurons was investigated. The interaction between NCX and mGluR1 in Purkinje neurons was studied by measuring intracellular Ca2+ transients induced by an agonist of group I mGluRs, 3,5-dihydroxyphenylglycine (DHPG). The DHPG-induced Ca2+ transient was significantly reduced by treatments of NCX inhibitors, bepridil and KB-R7943. When cells were pretreated with antisense oligodeoxynucleotides of NCX, the DHPG-induced Ca2+ transient was also inhibited. These results suggest that NCX modulates the activity of mGluR1 in cerebellar Purkinje neurons. Therefore, NCX appears to play an important role in the physiological function of cerebellar Purkinje neurons such as synaptic plasticity.

Abstract
Emergency situations can occur anywhere and anytime in daily life. In the paper, we present an e-health system to perceive emergency situations of a patient. Using a wearable shirt (BioShirt) and a personal monitoring system (PBM), we obtain the body signals of a user. The monitoring system collects and transmits the vital signs to a personal digital assistant (PDA) via a BlueTooth communication module. To detect emergency from the received data, a simple detection algorithm is performed in the PDA. And the PDA forwards the data to an e-health central monitoring room (ECMR), if necessary. In the ECMR, several operators supervise the registered users based on incoming body signals from each user's device. If an automatic decision-making algorithm generates an emergency alarm, the operators try to contact the corresponding patient and recognize his status. Ultimately if they decide that the patient is an urgent situation, they give phone calls and messages to the emergency center and the patient's medical attendant immediately.

Abstract
OBJECTIVE To examine the effects of alpha (s1)-casein hydrolysate on females with stress-related symptoms. DESIGN Double-blind, randomized, crossover, placebo-controlled trial. SETTING The alpha (s1)-casein hydrolysate was manufactured by INGREDIA (Arras, France) and the placebo was manufactured by DIETAROMA (Bourg, France). Study was designed and performed at PROCLAIM (Rennes, France), and the statistical analyses were performed by D Desor (Nancy, France). SUBJECTS A total of 63 female volunteers suffering from at least one disorder that may be related to stress such as anxiety, sleep problems and general fatigue. INTERVENTIONS A total of 63 volunteers participated in a double-blind, randomized, crossover, placebo-controlled study. Subjects were randomly allocated to receive either tablets containing alpha (s1)-casein hydrolysate or placebo at the dose of 150 mg/day for 30 days. After a 3 weeks washout period, they were crossed over for a new 30-day period of tablets intake. The outcome measure was a questionnaire including 44 items of symptoms that may be related stress in which the severity of each sign was evaluated using a 10-degree scale. These measures were studied repeatedly at the day of 0, 15 and 30 after the start of each interventional period. RESULTS The 30-day treatment by alpha (s1)-casein hydrolysate in females with stress-related symptoms reduced their symptoms, particularly in digestion (P<0.01), cardiovascular (P<0.05), intellectual (P<0.01), emotional (P<0.05) and social problems (P<0.05). CONCLUSION This study showed that a 30-day ingestion of alpha (s1)-casein hydrolysate decreased the stress-related symptoms in females suggesting that this product may be used as an effective functional ingredient alleviating such symptoms. SPONSORSHIP This study was partially supported by the INGREDIA of France and Neurobiology Research Program from the Korea Ministry of Science and Technology (2004-01757) of Korea.

Abstract
OBJECTIVES To evaluate the clinicopathologic prognostic factors of uterine sarcoma, and determine whether overexpression of p53 and mdm-2 proteins correlate with overall survival and prognostic factors. METHODS Thirty specimens from 43 patients with uterine sarcoma were available for slide review and evaluated by immunohistochemistry at Yonsei and Ajou University Medical Centers for the expression of p53 and mdm-2. RESULTS Overall survival was found to correlate to histologic type of uterine sarcoma, surgical stage, tumor grade, and mitotic index. Whereas 63% of the sarcomas expressed p53, with a significant correlation to overall survival, 60% expressed mdm-2, with a significant correlation to the mitotic index but not to overall survival. CONCLUSION Histologic type, surgical stage, tumor grade, mitotic index, and p53 expression were prognostic factors of the overall survival of patients with uterine sarcoma.

Abstract
The objective of this study was to review the clinical outcome and prognosis of patients with primary peritoneal carcinoma (PPC) treated with cytoreductive surgery and combination chemotherapy. We retrospectively reviewed the charts of 27 patients with histologically confirmed PPC, treated between March 1990 and February 2004 at Asan Medical Center, South Korea. The review included demographic data, pathologic findings, treatments, and outcomes. The mean age of the 27 patients was 57.5 +/- 7.2 years, and the rate of optimal cytoreduction was 70.4%. Seven patients had stage IIIB, 17 had stage IIIC, and 3 had stage IV; all patients received adjuvant chemotherapy. There were 4 patients with progressive disease, 5 partial responders, and 15 complete responders; the remaining 3 patients were nonevaluable. At the time of the review, 10 patients were alive without evidence of disease, 3 were alive with disease, and 14 had died from disease. The median overall survival time was 41 months, and the overall 5-year survival rate was 18.1%. Patients who had optimal cytoreduction had a longer median survival (42 months) than those who had suboptimal cytoreduction (10 months; P < 0.05). Combination chemotherapy after optimal cytoreductive surgery may be effective in the treatment of patients with PPC.

Abstract
Although surgical lung resection could improve prognosis in some patients with multidrug-resistant tuberculosis (MDR-TB), there are no reports on the optimal candidates for this surgery. The aim of the present study was to elucidate the prognostic factors for surgery in patients with MDR-TB. Patients who underwent lung resection for the treatment of MDR-TB between March 1993 and December 2004 were included in the present study. Treatment failure was defined as greater than or equal to two of the five cultures recorded in the final 12 months of treatment being positive, any one of the final three cultures being positive, or the patient having died during treatment. The variables that affected treatment outcomes were identified through univariate and multivariate logistic regression analysis. In total, 79 patients with MDR-TB were included in the present study. The treatment outcomes of 22 (27.8%) patients were classified as failure. A body mass index <18.5 kg x m(-2), primary resistance, resistance to ofloxacin and the presence of a cavitary lesion beyond the range of the surgical resection were associated with treatment failure. Low body mass index, primary resistance, resistance to ofloxacin and cavitary lesions beyond the range of resection are possible poor prognostic factors for surgical lung resection in multidrug-resistant tuberculosis patients.
