RESUMEN

OBJECTIVE: Surgical resection of asymptomatic primary colorectal cancer in patients presenting with synchronous unresectable metastatic disease is controversial. Concerns and controversies remain over combining cytotoxic chemotherapy with bevacizumab in this patient population. METHODS: We identified medical records of 99 patients with synchronous metastatic primary colorectal cancer who received chemotherapy with bevacizumab as their initial treatment. The incidence of subsequent use of surgery and surgical outcomes were recorded. Patients were also assessed for overall survival. RESULTS: Patients who received bevacizumab-containing chemotherapy for synchronous metastatic primary colorectal cancer were divided into the non-surgery and surgery groups according to the resection status of their asymptomatic primary tumor. In the non-surgery group, two patients (4.4%) underwent additional surgery, while three patients (5.7%) required surgery for rectovesical fistula in the surgery group. The median overall survival was 17 months for the non-surgery group (95% CI: 10.6-23.3 months) and 23 months for the surgery group (95% CI: 21.3-24.6 months; P = 0.322). CONCLUSIONS: This study utilizing chemotherapy with bevacizumab did not result in an increased rate of morbidity related to the unresected primary tumor. Survival is not compromised by leaving the primary colon tumor intact.

RESUMEN

BACKGROUND/AIMS: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasm of the gastrointestinal tract. In an attempt to survey the approximate incidence, clinicopathological characteristics, and immunophenotypic features of GISTs in Turkey, we conducted a clinicopathological and immunohistochemical analysis of GISTs. METHODOLOGY: Three hundred and thirty-three patients with GIST from nine institutions in Turkey were retrospectively evaluated. RESULTS: Between January 2001 and March 2011, a total of 333 patients with GISTs were included; of these, 204 (61.2%) were male and 129 (38.8%) were female. The median age was 55 years (range; 22-102 years). At the median follow-up of 26 months (range; 4-166 months), the 1-, 3- and 5-year OS rates of the 333 patients were 96.9%, 85.8% and 78.5%, respectively. The 5-year DFS rate was 40%. The 5-year OS rate and median OS time for the patients with R0 resection were significantly higher than for patients with metastatic diseases (79.7 vs. 75.7% and not reached vs. 115 months, respectively, p=0.04). CONCLUSION: Although our results should be confirmed by prospective studies, we believe that they contribute to the literature because the study included both resectable and metastatic or unresectable GIST patients and multicenter findings from Turkey.

RESUMEN

BACKGROUND/AIMS: The aims of this study were to report the clinical outcomes of adjuvant chemo-radiotherapy after curative resection in 637 patients with gastric cancer. METHODOLOGY: The retrospective analysis included 637 patients with resectable gastric cancer and stage IB-IV (M0) from 8 medical centers between 2003 and 2010. The patients were treated with 5FU-leucovorin and radiotherapy according to Schema for INT-0116. RESULTS: Of the 637 patients, the median of overall survival (OS) was 43.7 months and relapse free survival (RFS) was 36.6 months. OS rates were 84%, 45%, 40% while RFS rates were 81%, 45% and 35% at 1, 3 and 5-years, respectively. Hematological and gastrointestinal toxicities (grade 1-4) were observed in 35% and 36.5% of patients, respectively. In univariate analysis, according to the Lauren classification, tumor grade, T stage, N stage, type of operation (total gastrectomy or subtotal) and surgery resection margin (R0 or R1) were found as prognostic factors on RFS and OS (p<0.05). In multivariate analysis, T stage, N stage and surgical margins were found as effective factors on OS. T stage, N stage and Lauren classification were factors affecting RFS. CONCLUSIONS: Adjuvant chemo-radiotherapy after curative resection of gastric cancer was feasible, with acceptable toxicities in the Turkish population.

RESUMEN

BACKGROUND: Malignant pleural mesothelioma (MPM) has a poor prognosis. OBJECTIVES: Only few studies in literature investigated the presence of pleural fluid and radiographic findings for the prognosis of MPM. METHODS: We retrospectively investigated the hospital charts of 363 MPM patients who were diagnosed from January 1989 to March 2010. Survival time was calculated by the Kaplan-Meier method. Pretreatment clinical, laboratory and radiographic features of each patient at the time of diagnosis were obtained from patients' charts. RESULTS: The mean age of 363 patients (217 men, 146 women) was 50.6 ± 11.2 years (range 19-85) and the mean survival time was 11.7 ± 8.6 months (range 1-53). Histological types of MPM were epithelial (71.2%), mixed (15.9%) and sarcomatous type (4.9%). The frequency of disease stages were 31.4% for stage 1, 24.2% for stage 2, 28.6% for stage 3 and 15.8% for stage 4. The most frequent symptoms were dyspnea (82.1%), chest pain (68.3%) and weight loss (58.9%). Results of univariate and multivariate analyses revealed that a Karnofsky performance score ≤60, a pleural fluid glucose level ≤40 mg/dl, a C-reactive protein level >50 mg/l, a serum lactate dehydrogenase level >500 U/l, the presence of pleural fluid, pleural thickening >1 cm and a platelet count of >420 × 10(3)/µl were found to be associated with poor prognosis in MPM. CONCLUSIONS: Our data suggest that low pleural fluid glucose and high C-reactive protein, the presence of pleural fluid and pleural thickening were associated with poor MPM prognosis. Further prospective studies are needed to highlight prognostic factors more clearly.

RESUMEN

BACKGROUND: The most common age at which gastric cancer is diagnosed is 70 years, and the majority of patients diagnosed are at the metastatic stage. However, although gastric cancer is a geriatric disease, there is no suggestion to discriminate treatment for the general geriatric patient population. Here, we evaluated patients receiving palliative chemotherapy for gastric cancer owing to advanced age. PATIENTS AND METHODS: Multicenter data of geriatric patients receiving palliative chemotherapy because of metastatic gastric cancer were retrospectively reviewed. RESULTS: In total, 262 geriatric patients with gastric cancer were included in the study. Of these, 167 patients, including 134 (51.8%) patients with metastasis at diagnosis and 33 patients with relapse after surgery, were evaluated for palliative therapy. Chemotherapy was started in 87 (52.1%) of 167 patients. The overall median survival of the patients receiving chemotherapy was 9.3 months. There was no difference in overall survival (OS) between patients aged >70 and <70 years. However, a significant difference was detected in OS of patients depending on their Eastern Cooperative Oncology Group (ECOG) performance status (PS) before treatment; survival was 15 months in the group with PS 0-1 and 7 months in the group with PS ≥2. CONCLUSION: Advanced age chemotherapy receiving rates in patients with metastatic gastric cancer is decreasing. Survival is not associated with age, but pretreatment ECOG PS is important. Therefore, ECOG PS and comorbidities should be evaluated in detail, and combination therapies could contribute to patient survival.

RESUMEN

Background: The synthesis of CDK4/6 inhibitors with endocrine treatment in two series of treatment has been widely accepted as the standard for patients with estrogen receptor-positive metastatic breast cancer. In spite of this, the activity of CDK4/6 inhibitors in patients with metastatic breast cancer who have progressed despite receiving multiple lines of treatment is not well understood. Aims: To report the activity and safety of a CDK4/6 inhibitor (palbociclib) in patients in whom at least three lines of treatment for ER+ metastatic breast cancer had failed. Study Design: Multicenter retrospective observational cohort study. Methods: In this retrospective observational cohort study, we included 43 patients who received palbociclib after at least three lines of systemic treatment for ER+/HER2− metastatic breast cancer. Results: The median progression-free survival in our population was 7 months (25th-75th percentile, 4-10), and the median overall survival was 11 months (25th-75th percentile, 6-19). Although there were some adverse events, palbociclib was generally well tolerated, so dose reduction was needed for only six patients (14%). Conclusion: The efficacy of palbociclib among heavily treated hormone receptor-positive/HER2− patients with advanced breast cancer was acceptable in terms of clinical benefit, and it was generally well tolerated among this population.

RESUMEN

BACKGROUND/AIMS: Acute pancreatitis (AP) is characterized by acute inflammation of the pancreas and it has a highly variable clinical course. The aim of our study was to evaluate the value of acoustic radiation force impulse (ARFI) elastography in the diagnosis and clinical course of AP. MATERIALS AND METHODS: Consecutive patients with a diagnosis of AP (patients group) and healthy subject (control group) were prospectively enrolled to the study. Demographic features and clinical, laboratory, and radiological data were recorded. Virtual Touch Tissue Quantification (VTQ) was used to implement ARFI elastography. The tissue elasticity is proportional to the square of the wave velocity (SWV). RESULTS: A total of 108 patients (age, 57±1.8 y) and 79 healthy subjects (age, 53.6±1.81 y) were included in the study. There were 100 (92.5%) edematous and 8 (7.4%) necrotizing AP. The mean SWV was significantly higher in the patient group than in the control group (2.43±0.08 vs. 1.27±0.025 m/s, p < 0.001). There was not significant difference between patient and control group regarding age and gender. SWV cutoff value of 1.63 m/s was associated with 100% sensitivity and 98% specificity for the diagnosis of AP. There was not significant difference between patients with and without complications and patients with edematous and necrotizing AP regarding mean SWV value. There was also not significant correlation between mean SWV value and age, mean length of hospital stay, and mean amylase level. CONCLUSION: ARFI elastography may be a feasible method for the diagnosis of AP, but it has no value for the prediction of clinical course of AP.

RESUMEN

AIM: The goal of this study is to evaluate possible factors affecting the survival of patients treated with gonadotropin-releasing hormone (GnRH) analogues. METHODS: Demographic characteristics, treatment modalities, overall survival (OS) and the possible factors affecting the survival a total of 554 premenopausal breast cancer patients in Turkey evaluated retrospectively. RESULTS: The median duration of GnRH analogues use was 22 ± 13.6 (range, 1-87) months. Patients were divided into three groups according to the duration of GNRH analogues use; 4-12 months (Group A), 13-24 months (Group B) and ≥25 months (Group C). Overall, 530 patients were analyzed; 23.2%, 45.8%, 30.9% of the patients were in Group A, B and C, respectively. The median follow-up duration was 34 ± 30.3 (range, 4-188) months. The OS in patients ≤35 years of age was found to be significantly longer than that of patients >35 years of age in Group B (log rank, P = 0.023). The disease-free survival of the patients in Group A was significantly shorter than that of patients in Group C (log rank, P = 0.003). The OS of Group A patients was significantly shorter in comparison to that of Group B and Group C patients (log rank, P = 0.000) and the OS of Group B patients was significantly shorter than Group C (log rank, P = 0,000). CONCLUSION: There is currently no definite data on the optimal duration of GnRH analogues use. One of the important results of this study that will provide an insight to the future studies is the improvement gained in OS by the increase in the duration of GnRH analogues use.

RESUMEN

BACKGROUND AND AIMS: Splenic artery aneurysm (SAA) rarely occurs in the general population. Its increased incidence has been reported in cirrhosis. The aim of this retrospective study was to identify prevalence and predictive factor development of SAA in patients with cirrhosis. METHODS: All patients with cirrhosis who were treated in our clinics between 2010 and 2014 were included in the study. Demographic features and clinical and laboratory findings were reviewed. Four-phase computerized tomography (CT) was used for identifying SAA. Imaging was reviewed for the presence of SAA as well as hepatic artery, portal vein, splenic artery, splenic vein, liver parenchyma, and intraabdominal cavity were evaluated. RESULTS: A total of 171 patients (age 55±13.9, 109 men) were included in the study. There was SAA in 27 (15.7 %) patients. Mean diameter of aneurysm was 11.66 (range, 6.06-27.1) mm. Aneurysm was located in the distal part of splenic artery in 20 (74 %) patients and solitary in 24 (88.8 %), and asymptomatic in all patients. Patients with SAA had larger portal vein and splenic vein compared to patients without SAA (15.3±3.9 vs. 13.1±2.9 mm, p=0.001; and 12.5±4.4 vs. 9.6±2.7 mm, p<0.001, respectively). We identified positive correlation between development of SAA and splenic vein diameter [hazard ratio (HR) =1.23; 95 % confidence interval (CI) 0.97-1.57; p = 0.009] and negative correlation between hepatic artery diameter and development of SAA HR = 0.46; 95 % CI 0.25-0.85; p = 0.002). CONCLUSION: SAA occurred in a significant proportion of patients with cirrhosis, and enlargement of the splenic vein seemed to be a predictive factor for the development of SAA.

RESUMEN

INTRODUCTION: The present study aimed to establish the epidemiological and clinical characteristics of patients who were histopathologically diagnosed with malignant melanoma (MM). METHODS: The present study retrospectively analyzed the data of 78 patients who were histopathologically diagnosed with MM in Dicle University Medical Faculty, Dermatology and Medical Oncology departments between 2005 and 2014. RESULTS: The study included 78 patients in total with 44 (56.4%) male and 34 (43.6%) female. Median age of the patients was 62.50 years (range: 27 - 84 years). Of the patients, 78.2% (n = 61) had cutaneous melanoma, 8.9% had solid organ melanoma, and 2.5% had ocular and mucosal melanoma. The most common tumor localization among the patients was the lower extremities with 29.4% (n = 23). The most common histopathological type was nodular malignant melanoma with 35.8% (n = 28). Based on TNM, Clark and Breslow classifications, 26.9% (n = 21) of the patients were stage 4, 26.9% (n = 21) were Clark stage 4, and 37.1% (n = 29) were Breslow stage 4. Median overall survival in all patients was 14.9 months (95% CI 10.9 - 18.8 months). In the multivariate Cox analysis, only stage statistically significantly affecting survival [odds ratio (OR): 0.54; (95% CI 0.16-1.82, p = 0.02)]. CONCLUSION: Malignant melanoma data are also important for the optimal utilization of effective methods and healthcare resources to prevent the disease. In order to minimize MM mortality and morbidity, not only the society but also physicians from primary and secondary care hospitals should become familiar with melanoma.

RESUMEN

BACKGROUND: Elevated serum alpha-fetoprotein (AFP) levels in adults are considered abnormal. This parameter is used mostly in the diagnosis and follow-up of hepatocellular carcinomas and yolk sac tumors. Among the other rare tumors accompanied with elevated serum AFP levels, gastric cancer is the most common. In this study, we evaluated the follow-up and comparison of the treatment and marker response of patients with metastatic gastric cancer who had elevated serum AFP levels. MATERIALS AND METHODS: We performed a retrospective study, including all consecutive patients with advanced gastric cancer, who received systemic chemotherapy with elevated AFP level. RESULTS: Seventeen metastatic gastric cancer patients with elevated AFP levels at the time of diagnosis were evaluated. Fourteen (82.4%) were males and three (17.6%) were females. The primary tumor localization was the gastric body in 8 (76.4%), cardia in 7 (41.2%), and antrum in 2 (11.8%). Hepatic metastasis was observed in 13 (76.4%) at the time of diagnosis. When the relationship of AFP levels and carcinoembryonic antigen (CEA) response of the patients with their radiologic responses was evaluated, it was found that the radiologic response was compatible with AFP response in 16 (94.1%) patients and with CEA response in 12 (70.6%); however, in 5 (29.4%) patients no accordance was observed between radiological and CEA responses. CONCLUSIONS: Follow-up of AFP levels in metastatic gastric cancer patients with elevated AFP levels may allow prediction of early treatment response and could be more useful than the CEA marker for follow-up in response evaluation.

RESUMEN

AIM: This study aimed to assess the clinical efficacy and toxicity of sunitinib, a targeted-agent, for non-clear cell renal cell carcinoma. PATIENTS AND METHODS: Sixty-three patients with complete clinical data from 13 oncology Centers were retrospectively evaluated. Outcomes analyzed were objective response rate (ORR), progression-free survival (PFS), overall survival (OS) and adverse events. RESULTS: The median age of all patients, 38 men (60.3%) and 25 women (39.7%), was 63 years (range=25-82 years). Histological subtypes included 46 (88%) cases of papillary RCC, 10 of chromophobe, and 7 unclassified cases. Median treatment duration was seven months (range=2-86 months). At the time of this analysis, 52 patients had discontinued treatment, 33 of whom had died. Treatment discontinuation was due to disease progression in 43 patients, and toxicity in nine. Dose interruption was necessary in 22 (34.9%) patients, and dose reduction in 27 (42.9%). The objective response rate and disease control rate were 11.1% and 63.5%, respectively. The median PFS and OS were 7.6 months (95% confidence interval (CI)=5.5-9.7 months) and 22.0 months (95% CI=13.4-30.6 months), respectively, with 1-year rates of 64.7% and 33.7%, respectively. CONCLUSION: Clinical outcome of the metastatic non-clear cell RCC patients with sunitinib treatment seemed to be worse than the historical data of clear cell RCC patients, in terms of PFS, OS and objective response. New and more effective targeted-therapies and better understanding of the underlying molecular processes are necessary to improve survival outcome for these patients.

RESUMEN

Lapatinib is the first dual tyrosine kinase inhibitor of human epidermal growth factor receptor type 2 (HER2/neu) and epidermal growth factor receptor (EGFR). The present study evaluated the efficacy and tolerability of the combination of lapatinib and capecitabine in patients with metastatic breast cancer (MBC) who progressed after therapy with trastuzumab, a taxane and/or anthracycline. A total of 203 patients with a median age of 48 years (range: 25-82 years) were evaluated retrospectively in 11 centres between September 2007 and May 2011. All the patients had HER2-positive MBC progressing after trastuzumab and chemotherapy including an anthracycline and/or taxane. All patients were treated with the combination of lapatinib (1250 mg/day, continuously) and capecitabine (2000 mg/m(2) on days 1 through 14 of a 21-day cycle). Data on demographics, clinical outcome, and toxicity were collected for descriptive analyses. The median follow-up was 10·7 months (range: 1-40 months). An overall response rate (ORR) of 33·4% was achieved including 7 complete responses (CR, 3·4%), 61 partial responses (PR, 30·0%), and 44 stable disease (37·9%). Clinical benefit rate of 71·3% was achieved. Median progression-free survival (PFS) was 7 months (95% CI: 6-10 months), with a median overall survival (OS) of 15 months (95% CI: 12-18 months). The most common side effects were hand-foot syndrome (46·8%), nausea (42·3%), fatigue (42·2%), anorexia (38·5%), diarrhea (31·5%), and rash (29·6%). Grade 3-4 toxicities were identified as hand foot syndrome (7·9%), diarrhea (6·9%), fatigue (5·9%), and rash (5·4%). There were no symptomatic cardiac events. Lapatinib and capecitabine combination therapy is effective and well tolerated in patients with MBC who had progressive disease after trastuzumab, taxane, and/or anthracycline therapy, as evidenced by this retrospective evaluation. Toxicity was mild to moderate with low grade 3-4 toxicity.

RESUMEN

BACKGROUND: The development of brain metastases (BMs) was associated with poor prognosis in melanoma patients. Patients with BMs have a median survival of <6 months. Melanoma is the third most common tumor to metastasize to the brain with a reported incidence of 10-40 %. Our aim was to identify factors predicting development of BMs and survival. PATIENTS AND METHODS: We performed a retrospective analysis of 470 melanoma patients between 2000 and 2012. The logistic regression analyses were used to identify the clinicopathological features of primary melanoma that are predictive of BMs development and survival after a diagnosis of brain metastases. RESULTS: There were 52 patients (11.1 %) who developed melanoma BMs during the study period. The analysis of post-BMs with Kaplan-Meier curves has resulted in a median survival rate of 4.1 months (range 2.9-5.1 months). On logistic regression analysis site of the primary tumor on the head and neck (p = 0.002), primary tumor thickness (Breslow >4 mm) (p = 0.008), ulceration (p = 0.007), and pathologically N2 and N3 diseases (p = 0.001) were found to be significantly associated with the development of BMs. In univariate analysis, tumor thickness and performance status had a significant influence on post-BMs survival. In multivariate analysis, these clinicopathologic factors were not remained as significant predictive factors. CONCLUSIONS: Our results revealed the importance of primary tumor characteristics associated with the development of BMs. Ulceration, primary tumor thickness, anatomic site, and pathologic ≥N2 disease were found to be significant predictors of BMs development.

RESUMEN

OBJECTIVE: In sero-diagnosis of parasitic infection, it is essential to inspect cross-reactivity between the target parasite and other parasites in order to assess diagnostic performance. The aim of this study was to determine the cut-off value of antibody titer for diagnosis of F. hepatica (FH) infection by using the micro-ELISA and diagnostic performance of this test. METHODS: The study population consisted of the following groups: FH group (n=42), Echinococcus granulosus (EG) group (n=27) and control group (n=33). The micro-ELISA test for detection of anti-F. hepatica antibody was performed in all groups. RESULTS: The test was positive in all patients with FH, in 3 out of 27 (11%) patients with EG and in none of the control group. Mean antibody titer was significantly higher in the FH group compared to the EG group (23.8 ± 0.9 DU vs. 5.7 ± 1.2 DU; p < 0.001) and compared to the control group (23.8 ± 0.9 DU vs. 2.4 ± 0.2 DU; p < 0.001). When we used 11,5 DU as a cut-off value for sero-diagnosis of FH, the positive predictive value was 93.3%, negative predictive value was 100%, sensitivity was 100%, and specificity was 95%. CONCLUSION: Cross-reactions are an important issue in serological diagnosis of parasitic infections. The micro-ELISA test for FH antibody can not definitely discriminate fascioliasis from hydatid disease.

RESUMEN

AIM: To determine the relationship between non-alcoholic steatohepatitis (NASH) and bone mineral density (BMD). METHODS: A total of 38 patients (25 males) with a diagnosis of histologically proven NASH and 42 healthy controls (24 males) were enrolled in the study. Demographic features, clinical findings, complete blood count and routine biochemical analysis, as well as adrenal, thyroid and gonadal functions, were recorded. Additionally, intact parathormone, 25-OH-vitamin-D3, tumor necrosis factor-α, interleukin-6, interleukin-1, insulin-like growth factor-1 and insulin-like growth factor binding protein-3 levels were measured in both groups. Furthermore, lumbar spine and femoral neck BMD of both groups were measured by the dual-energy X-ray absorptiometry (DXA) method. RESULTS: The mean age was 41 ± 12 years in the NASH group and 43 ± 11 years in the control group. Among demographic features, waist circumference was significantly larger in the NASH group compared to the control group (P < 0.019). Among laboratory parameters, serum triglyceride (P < 0.008), alanine transaminase (P < 0.0001), aspartate transaminase (P < 0.001), alkaline phosphatase (P < 0.016), gamma glutamyl transferase (P < 0.0001), ferritin (P < 0.001) and 25-OH-vitamin-D3 levels (P < 0.0001) were significantly higher in the NASH group compared to the control group. Lumbar BMD was significantly higher in the NASH group compared to the control group (1.057 ± 0.119 g/cm(2) vs 0.941 ± 0.133 g/cm(2); P < 0.001, respectively). In the NASH group, there was no significant relationship between BMD and fibrosis stage in liver biopsy. CONCLUSION: NASH increases BMD and may be related to an elevated serum 25-OH-vitamin D3 level.

RESUMEN

BACKGROUND: Tyrosine kinase inhibitor is a standard treatment for mRCC. The NLR, an index of systemic inflammation, is associated with outcome in several cancer types. To study the association of pretreatment NLR with PFS and overall survival (OS) of patients treated with VEGF-targeted therapy. PATIENTS AND METHODS: We retrospectively studied an unselected cohort of patients with mRCC, who were treated with TKIs. Kaplan-Meier and log-rank analyses were employed on PFS and OS and multivariate Cox proportional hazard model analyzed clinical parameters for their prognostic relevance. RESULTS: A total of 100 patients with mRCC who had early progressed after first-line therapy with interferon-α were included in this retrospective multicenter study conducted at 4 centers between February 2008 and December 2011. The median of the NLR was 3.04 and patients were divided into 2 higher and lower NLR groups according to median of NLR. Median PFS was 9 versus 11 months in patients with baseline NLR > 3.04 versus ≤ 3.04 (P = .009). The median OS was 16 months versus 29 months, in patients with NLR > 3.04 versus ≤ 3.04, respectively (P = .004). In the whole group OS was independently associated with higher NLR (hazard ratio [HR], 2.406; P = .004), PFS more than 6 months (HR, 4.081; P = .0001), and sex (HR, 2.342; P = .040). On the other hand in the higher NLR group (HR, 1.107; P = .009) Memorial Sloan-Kettering Cancer Center score (HR, 3.398; P = .0001) was associated with PFS. CONCLUSION: In patients with mRCC treated with VEGF-targeted therapy, pretreatment NLR, the duration of PFS might be associated with OS. This should be investigated prospectively.

RESUMEN

BACKGROUND: Inoperable and metastatic hepatocellular carcinoma (HCC) is associated with a poor prognosis and low chemotherapeutic efficiency. Sorafenib is an oral multi-kinase inhibitor exerting its effects via the RAF/ MEK/ERK pathway, vascular endothelial growth factor receptor (VEGFR) and platelet derived growth factor receptor beta (PDGFR-ß) tyrosine kinases. Randomized studies have shown a significant contribution of sorafenib to life expectancy and quality of life of cancer patients. The aim of the present study is to evaluate the efficacy and side effects of sorafenib therapy in Turkey. MATERIALS AND METHODS: Data for 103 patients (82 males, 21 females) receiving sorafenib therapy in 13 centers from February 2008 to December 2012 were evaluated. Median age was 61 years and median ECOG performance status was 1 (range: 0-2). 60 patients (58%) had hepatitis B, 15 patients (15%) had hepatitis C infection and 12 patients (12%) had a history of alcohol consumption. All of the patients had Child scores meeting the utilization permit of the drug in our country (Child A). RESULTS: A total of 571 cycles of sorafenib therapy were administered with a median of four per patient. Among the evaluable cases, there was partial response in 15 (15%), stable disease in 52 (50%), and progressive disease in 36 (35%). Median progression-free survival was 18 weeks and median overall survival was 48 weeks. The dose was reduced only in 6 patients and discontinued in 2 patients due to grade 3-4 toxicity, 18 patients (17%) suffering hand-foot syndrome, 7 (7%) diarrhea, and 2 (2%) vomiting. CONCLUSIONS: This retrospective study demonstrated better efficacy of sorafenib therapy in patients with advanced HCC compared to the literature while progression-free survival and overall survival findings were comparable. The side effect rates indicate that the drug was tolerated well. In conclusion, among the available treatment options, sorafenib is an efficient and tolerable agent in patients with inoperable or metastatic HCC.

RESUMEN

BACKGROUND/AIMS: Parasitic helminths express some antigen, which often accounts for serological cross-reactions. The aim of this study was to determine the prevalence of anti-Echinococcus granulosus antibody in patients with Fasciola hepatica infection using indirect immunofluorescence assay. MATERIALS AND METHODS: The study population consisted of the following groups: Fasciola hepatica group (n=22), hydatid disease group (n=22) and healthy control group (n=24). Indirect immunofluorescence assay for Echinococcus granulosus was performed in all groups. RESULTS: Indirect immunofluorescence assay was positive in all patients with hydatid disease, in 13 of 22 (59%) patients with fascioliasis and in 2 of 24 (8%) healthy subjects. The positivity rate of indirect immunofluorescence assay was significantly higher in the hydatid disease group compared to the fascioliasis group (p<0.001) and compared to the control group (p<0.001), and it was significantly higher in the fascioliasis group compared to the control group (p=0.001). Antibody titer was 1/100 in 7 patients, 1/320 in 12 patients and 1/1000 in 3 patients with hydatid disease. Indirect immunofluorescence assay was positive in 10 of 15 patients with hepatic phase and in 3 of 7 patients with biliary phase of fascioliasis. The antibody titer was 1/100 in 6 and 1/320 in 7 patients with fascioliasis. The antibody titer was 1/100 in both healthy subjects. CONCLUSIONS: Indirect immunofluorescence assay for Echinococcus granulosus may be positive in a majority of patients with Fasciola hepatica infection and in some healthy subjects.

RESUMEN

AIM: To identify the frequency of bacterial growth, the most commonly grown bacteria and their antibiotic susceptibility, and risk factors for bacterial colonization in bile collected from patients with different biliary diseases. METHODS: This prospective study was conducted between April 2010 and August 2011. Patients with various biliary disorders were included. Bile was aspirated by placing a single-use, 5F, standard sphincterotome catheter into the bile duct before the injection of contrast agent during endoscopic retrograde cholangiopancreaticography (ERCP). Bile specimens were transported to the microbiology laboratory in blood culture bottles within an anaerobic transport system. Bacteria were cultured and identified according to the standard protocol used in our clinical microbiology laboratory. The susceptibilities of the organisms recovered were identified using antimicrobial disks, chosen according to the initial gram stain of the positive cultures. RESULTS: Ninety-one patients (27% male, mean age 53.7 ± 17.5 years, range: 17-86 years) were included in the study. The main indication for ERCP was benign biliary disease in 79 patients and malignant disease in 12 patients. The bile culture was positive for bacterial growth in 46 out of 91 (50.5%) patients. The most frequently encountered organisms were Gram-negative bacteria including Escherichia coli (28.2%), Pseudomonas (17.3%) and Stenotrophomonas maltophilia (15.2%). There were no significant differences between patients with malignant and benign disease (58% vs 49%, P = 0.474), patients with acute cholangitis and without acute cholangitis (52.9% vs 50%, P = 0.827), patients who were empirically administered antibiotics before intervention and not administered (51.4% vs 60.7%, P = 0.384), with regard to the bacteriobilia. We observed a large covering spectrum or low resistance to meropenem, amikacin and imipenem. CONCLUSION: We did not find a significant risk factor for bacteriobilia in patients with biliary obstruction. A bile sample for microbiological analysis may become a valuable diagnostic tool as it leads to more accurate selection of antibiotics for the treatment of cholangitis.
