Abstract
BACKGROUND ABVD (doxorubicin, bleomycin, vinblastine (Vb) and dacarbazine) is the standard regimen in Hodgkin's lymphoma (HL).Vincristine (O) is a mitotic spindle agent like Vb. We aimed to evaluate the efficacy and safety of O as a part of ABOD in HL. MATERIALS AND METHODS Patients who had ABOD were enrolled. Stage I-II HL were evaluated for unfavorable risk factors according to NCCN. National Cancer Institute Common Toxicity Criteria was used for toxicity. RESULTS Seventy-nine HL patients in our center between 2003 and 2007 were evaluated retrospectively. Median follow-up was 54 months. Most of the patients were male in their third decade. Median ABOD cycles were 6 (2-8). Primary refractory disease rate was 17.7% whereas it was 5.1% for early relapse and 5.1% for late relapse disease. Response rates were as 82.3% for complete response, 11.4% for partial response, 5.1% for stable disease and 1.3% for progressive disease. Half of relapsed patients had autologous stem cell transplantation. Estimated 5-year failure-free survival was 71% and significantly longer in early stage patients without risk factors, bulky disease or radiotherapy (RT) (p=0.05, p<0.0001, p=0.02; respectively). Estimated 5-year overall survival was 74% and significantly longer in those who had no RT (p=0.001). Dose modification rate was 5.1% and chemotherapy delay rate was 19%. There were no toxicity- related deaths. CONCLUSIONS ABOD seems to be effective with managable toxicity in HL, even in those with poor prognostic factors.

Abstract
AIMS The aim of the present study was to obtain the first data for the phosphatidylinositol-4,5-bisphosphate 3-kinase (PIK3CA) mutation frequency among nonsmall-cell lung cancer (NSCLC) patients in Turkey. All exons of the PIK3CA gene were investigated by sequence analysis in 40 NSCLC tumor tissue samples. RESULTS The 1634A>C mutation, which has previously been identified in many cancers including NSCLC, was identified in three tumor tissue samples in the present study. Interestingly, a second mutation (1658_1659delGTinsC) was also identified in these patients. The concurrence of these two mutations has been reported as the Cowden syndrome, which is known to be a cancer predisposition syndrome. This finding is important since it may be an indicator of the underlying cancer predisposition syndrome in NSCLC patients. Moreover, four novel mutations were identified in the present study. However, in vitro studies are required to evaluate the effects of these mutations on kinase activation. CONCLUSIONS The high frequency of PIK3CA mutations exerts important clinical implications for targeted therapy. This finding indicates that therapeutic agents targeting the phosphatidylinositol 3-kinase (PI3K) would be beneficial in the NSCLC subpopulation.

Abstract
BACKGROUND For HER2 positive metastatic breast cancer (MBC), continuing anti-HER2 therapy beyond progression is associated with improved outcome. However retreatment with trastuzumab after lapatinib progression is controversial. We retrospectively analyzed the efficacy of trastuzumab-based chemotherapy in HER2+ metastatic breast cancer patients whose disease progressed after lapatinib. MATERIALS AND METHODS Between October 2010 and May 2013, 54 patients whose disease progressed after lapatinib were retreated with trastuzumab-based chemotherapy. Efficacy and toxicity results were evaluated retrospectively. RESULTS The median age of patients was 46 (range 27-67). Fourteen patients (26%) had metastases at the time of diagnosis. All of the patients had received trastuzumab in an adjuvant or metastatic setting, while 16 (30%) had received two lines of trastuzumab. All patients had received lapatinib plus capecitabine. The median chemotherapy line for the metastatic setting was 2 (range 1-7). Cranial metastases were identified in 27 (50%) patients. 53 patients received trastuzumab-based chemotherapy following lapatinib progression while one patient received trastuzumab monotherapy. Combination chemotherapy consisted of navelbin (n=33), taxane (n=10), gemcitabine (n=2), platinum (n=2) and platinum with taxane (n=6). The median treatment cycle was 5 (range 1-44). Among 49 patients assessed for response 2 (4%) showed CR, 12 (25%) PR, 11 (22%) SD and 24 (49%) disease progression. Asymptomatic cardiotoxicity was reported in 2 (4%) of the patients. At a median follow-up of 9 months (1-39), median progression-free survival was 5 months (95% CI 4.1-5.9) and median overall survival was 10 months (95% CI 6.9-13.0). PFS and OS were not affected by the absence/presence of cranial metastases. CONCLUSIONS Retreatment with trastuzumab-based therapy after lapatinib progression showed efficacy in heavily treated MBC patients.

Abstract
BACKGROUND/AIMS The association between platelet-lymphocyte ratio (PLR), neutrophil-lymphocyte ratio (NLR), and survival with response rates were evaluated in metastatic gastric cancer (MGC). PATIENTS AND METHODS MGC patients on firstline modified docetaxel/cisplatinum/5-fluorourasil [mDCF; docetaxel 60 mg/m2 (days 1-5), cisplatin 60 mg/m2 (day 1), 5FU 600 mg/m2 (days 1-5), q3w] were evaluated retrospectively. The cutoff values were 160 for PLR and 2.5 for NLR. Progression-free survival (PFS) and overall survival (OS) were estimated for group I (PLR >160), group II (PLR ≤ 160), group III (NLR ≥ 2.5), group IV (NLR < 2.5), group V (PLR > 160 and NLR ≥ 2.5), group VI (PLR ≤ 160 and NLR <2.5), and group VII [VIIa (PLR > 160 and NLR < 2.5) and VIIb (PLR ≤160 and NLR ≥ 2.5)]. RESULTS One hundred and nine MGC patients were evaluated for basal hematological parameters and survival analysis, retrospectively. Most of the patients were male in their fifties with grade III adenocarcinoma (62.9%) and liver metastasis (46.7%). Patients with PLR > 160 and/or NLR ≥ 2.5 had significantly shorter PFS and OS (P = 0.04, 0.01, 0.019, and P = 0.003, 0.002, 0.000, respectively). CONCLUSION High PLR (> 160) and/or NLR (≥ 2.5) seem to be poor prognostic factors in MGC.

Abstract
The present study aimed to compare the effects of sevoflurane (a commonly used inhalation anesthetic) and intravenous propofol on middle ear pressure (MEP) and determine the more appropriate option for middle ear operations. Fifty-seven American Society of Anesthesiologists risk class I-II patients aged 18-65 years who were not scheduled for ear or tympanic membrane operations were included in the study. The patients were randomly divided into two groups using the sealed envelope method. Propofol (0.2-0.5 mg/kg; Group P) and sevoflurane (1-2%; Group S) were used to maintain anesthesia. Baseline tympanometry was conducted on both ears and recorded before anesthesia was induced. Four additional measurements were performed and recorded at 5, 10, 15, and 30 minutes after induction. All post-induction MEP values were significantly higher than baseline measurements in Group S (P < 0.05 for all); there were no differences between post-induction and baseline measurements in Group P. At 10, 15, and 30 min post-induction, MEP values were significantly higher in Group S than in Group P (P < 0.05). Sevoflurane increased MEP values significantly compared with propofol anesthesia. We conclude that propofol can be used more reliably than sevoflurane in middle ear operations.

Abstract
OBJECTIVES It has been demonstrated that decreased left ventricular ejection fraction (LVEF) is associated with an increased risk of contrast-induced nephropathy (CIN). In this study, we aimed to assess whether there is a relationship between left ventricular (LV) diastolic dysfunction and renal function decline after coronary angiography (CAG). PATIENTS AND METHODS The study consisted of two groups: group I, patients with normal diastolic function; group II, patients with cardiac symptoms and abnormal diastolic function. Serum creatinine (Crea) and glomerular filtration rates (GFR) were measured before and after 48 h of CAG. RESULTS After the procedure, serum Crea values were higher in group II compared with group I (p = 0.051). Postprocedural 48-h GFR values determined by Cockcroft-Gault and Modification of Diet in Renal Disease (MDRD) equations were lower in group II compared with group I (p = 0.016 and p = 0.003, respectively). Delta (Δ) ΔCrea and ΔGFR determined by the Cockcroft-Gault and MDRD equations were statistically higher in group II than in group I (p = 0.005, p = 0.052, p = 0.030). The presence of higher age (p = 0.025), E/E' lateral ratio (p = 0.030), and left atrial volume index (p = 0.05) were independent predictors of worsening renal function. CONCLUSION The presence of diastolic dysfunction may play a role in determining the risk of CIN in patients with normal LVEF.

Abstract
The purpose of this investigation was to compare the efficacy of colistin-based therapies in extremely drug-resistant Acinetobacter spp. bloodstream infections (XDR-ABSI). A retrospective study was conducted in 27 tertiary-care centers from January 2009 to August 2012. The primary end-point was 14-day survival, and the secondary end-points were clinical and microbiological outcomes. Thirty-six and 214 patients [102 (47.7%): colistin-carbapenem (CC), 69 (32.2%): colistin-sulbactam (CS), and 43 (20.1%: tigecycline): colistin with other agent (CO)] received colistin monotherapy and colistin-based combinations, respectively. Rates of complete response/cure and 14-day survival were relatively higher, and microbiological eradication was significantly higher in the combination group. Also, the in-hospital mortality rate was significantly lower in the combination group. No significant difference was found in the clinical (p = 0.97) and microbiological (p = 0.92) outcomes and 14-day survival rates (p = 0.79) between the three combination groups. Neither the timing of initial effective treatment nor the presence of any concomitant infection was significant between the three groups (p > 0.05) and also for 14-day survival (p > 0.05). Higher Pitt bacteremia score (PBS), Acute Physiology and Chronic Health Evaluation II (APACHE II) score, Charlson comorbidity index (CCI), and prolonged hospital and intensive care unit (ICU) stay before XDR-ABSI were significant risk factors for 14-day mortality (p = 0.02, p = 0.0001, p = 0.0001, p = 0.02, and p = 0.01, respectively). In the multivariable analysis, PBS, age, and duration of ICU stay were independent risk factors for 14-day mortality (p < 0.0001, p < 0.0001, and p = 0.001, respectively). Colistin-based combination therapy resulted in significantly higher microbiological eradication rates, relatively higher cure and 14-day survival rates, and lower in-hospital mortality compared to colistin monotherapy. CC, CS, and CO combinations for XDR-ABSI did not reveal significant differences with respect to 14-day survival and clinical or microbiological outcome before and after propensity score matching (PSM). PBS, age, and length of ICU stay were independent risk factors for 14-day mortality.

Abstract
BACKGROUND Whether to perform colorectal cancer and liver metastasis resections simultaneously or in separate procedures is controversial. The aim of the present study was to investigate the effect of the Pringle manoeuvre on the healing of left-sided colonic anastomoses in rats. METHODS Sixteen rats were randomly separated into two groups. In Groups 1 and 2, 1 cm of descending colon was resected and a primary anastomosis was performed. In Group 2, an intermittent pedicle clamp (the Pringle manoeuvre) was performed. On postoperative day 5, laparotomy was performed and the bursting pressures of all colon anastomoses were determined. Tissues were sampled for assay of hydroxyproline levels. Cultures of intraperitoneal swabs were also performed. RESULTS Clostridium was twice as abundant in the Pringle manoeuvre group as in the control group (p < 0.05). Anastomosis-bursting pressures and tissue hydroxyproline levels were significantly lower in the Pringle manoeuvre group than in the control group (p < 0.05). CONCLUSIONS The Pringle manoeuvre may compromise the viability of colonic anastomoses.

Abstract
AIM Facioscapulohumeral muscular dystrophy (FSHD) is an autosomally inherited neuromuscular disorder and may be associated with increased cancer risk. PATIENT A 69-year old female admitted to hospital with complaint of left axillary mass who had diagnosis of FSHD in her adulthood period. RESULTS Bilateral breast cancer diagnosis was made and the patient underwent bilateral mastectomy. Following the operation, adjuvant chemotherapy and radiotherapy performed and hormonal therapy started. CONCLUSION The patients with congenital muscular dystrophy might have an increased risk of malignancy. We consider that some genetic alterations in FSHD might have contributed to the development of bilateral breast cancer in our patient.
