RESUMO

PURPOSE: The aim of this retrospective study was to compare the different treatment options of patients with advanced biliary tract carcinoma (BTC) who were treated with platinum-gemcitabine (CG) or platinum-5-fluorouracil (CF) or 5-Fluorouracil-oxaliplatin-irinotecan (FOLFIRINOX) chemotherapy. METHODS: We included the patients with advanced BTC who were registered at the Department of Oncology in Gaziantep University between January 2008 and January 2016. The following data were analyzed: disease control rate (DCR), progression free survival (PFS) of first and second-line of chemotherapy, and overall survival (OS). Kaplan-Meier method and Log-rank test was used to compare two survival curves, and hazard regression model was used to evaluate risk factors for PFS. RESULT: Ninety-two patients were recruited. 53 (57.6 %), 27 (29.3 %), and 12 (13 %) patients received CG, CF, and FOLFIRINOX regimen as first-line chemotherapy, respectively. Median PFS and DCR of CG group were 22 weeks and 56.6 %, and these were 12 weeks and 44.4 % for CF group, and 9 weeks and 41.7 % for FOLFIRINOX group. Median OS of CG, CF, and FOLFIRINOX groups was 28, 21,and 23.5 weeks, respectively (p = 0.497). Second-line PFS of fluoropyrimidine-based chemotherapy group and gemcitabine-based chemotherapy group was 12 vs. 14 weeks (p = 0.988). Second-line PFS of FOLFIRINOX was 20 weeks, whereas it was 14 weeks for other fuoropyrimidine-based chemotherapies (p = 0.190). CONCLUSIONS: This was the first study evaluating the FOLFIRINOX regimen in BTC. Cisplatin-gemcitabine therapy still provides better survival in BCT. However, FOLFIRINOX can be an option in the second-line treatment of BTC patients who are eligible for chemotherapy.

RESUMO

PURPOSE: The aim of this study is to clarify the relationship between recurrence risk of breast cancer and methylenetetrahydrofolate reductase (MTHFR) C677T polymorphisms. PATIENTS AND METHODS: Breast cancer patients who had undergone surgery in Gaziantep University Oncology Hospital between June 2005 and June 2012 were followed-up and retrospectively enrolled in this study. Blood samples were collected from all patients to assess MTHFR C677T polymorphisms. Stage according to tumor-node-metastasis system, estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2 status, grade of disease, menopausal status, and administered chemotherapy or hormonal therapy were recorded. Effects of these parameters on recurrence risk were evaluated using univariate analysis and multivariate binary logistic regression model. RESULTS: Association of MTHFR C677T polymorphisms with recurrence risk was evaluated in 298 patients whose median age was 47 years (range: 21-79 years). In all patients, age (odds ratio [OR] =0.953, P=0.005) and N3 lymph node status (OR =6.293, P=0.001) were found to affect the recurrence risk. While MTHFR homozygote genotype did not have an effect on recurrence risk in all patients, increased risk was observed in lymph node-positive subgroup (OR =4.271; 95% CI 1.515-12.023; P=0.006). Adjusting for age, tumor size (T), and node status (N), MTHFR homozygote genotype had more statistically significant risk for recurrence (OR =3.255; 95% CI 1.047-10.125; P=0.041). CONCLUSION: MTHFR TT genotype was found to be associated with increased recurrence risk in patients with lymph node-positive breast cancer.

RESUMO

BACKGROUND: Interindividual variability of pharmacogenetics may account for unpredictable neurotoxicities of taxanes. METHODS: From March 2011 to June 2015, female patients with operable breast cancer who had received docetaxel- or paclitaxel-containing adjuvant chemotherapy were included in this study. All patients were treated with single-agent paclitaxel intravenously (IV) 175 mg/m(2) every 3 weeks for four cycles, or IV 80 mg/m(2) weekly for 12 cycles, and IV 100 mg/m(2) docetaxel for four cycles as adjuvant treatment. We evaluated the relationship between neurotoxicity of taxanes and single-nucleotide polymorphisms of ABCB1, CYP3A4, ERCC1, ERCC2, FGFR4, TP53, ERBB2, and CYP2C8 genes. Taxane-induced neurotoxicity during the treatment was evaluated according to the National Cancer Institute Common Toxicity Criteria version 4.03 prior to each cycle. Chi-squared tests were used to compare the two groups, and multivariate binary logistic regression models were used for determining possible risk factors of neuropathy. RESULTS: Pharmacogenetic analysis was performed in 219 females. ABCB1 3435 TT genotype had significantly higher risk for grade ≥2 neurotoxicity (odds ratio [OR]: 2.759, 95% confidence interval [CI]: 1.172-6.493, P: 0.017) compared to TC and CC genotype, and also CYP3A4 392 AA and AG genotype had significantly higher risk for grade ≥2 neurotoxicity (OR: 2.259, 95% CI: 1.033-4.941, P: 0.038) compared to GG genotype. For FDGF4 gene with AG and GG genotype, OR was 1.879 (95% CI: 1.001-3.525, P: 0.048) compared to AA genotype with regard to any grade of neuropathy risk. We could not find any other association of other genotypes with neurotoxicity grades. CONCLUSION: ABCB1 3435 TT genotype and CYP3A4 392 AA/AG genotypes may be used as predictors of neurotoxicity during taxane chemotherapy.

RESUMO

The present study reports the case of a collision tumor consisting of follicular lymphoma (FL) and adenocarcinoma in the cecum of a 73-year-old man. To the best of our knowledge, the present study is the 11th case of a collision tumor consisting of colon adenocarcinoma and lymphoma to be reported in the literature, and the first case of cecum adenocarcinoma with low grade FL in the same segment of the cecum and the same regional lymph node to be reported. The present study reviewed the literature to determine treatment options for patients with collision tumors. The present patient was administered with adjuvant chemotherapy for T3N1M0 colon cancer following surgery, due to the dominance of colon adenocarcinoma in the collision tumor. Following the completion of treatment, progression of the untreated FL was observed. In the literature, patients with collision tumors are administered with chemotherapy for stage IV FL, and following the completion of treatment patients have presented with a recurrence of early stage colon adenocarcinoma. The recommended treatment for collision tumors is dependent on the dominant tumor; however, the treatment options for collision tumors in the literature appeared to exacerbate the other tumor. The characteristics of the tumors altered following chemotherapy, and immunological alterations in the tumors due to chemotherapy appear to have contributed to the exacerbation of the tumors. Therefore, patients with early-stage tumors should be considered at risk of recurrence of other malignancies, which are present in collision tumors.

RESUMO

PURPOSE: The number of patients who make it to receive third-line chemotherapy is increasing owing to the improvements in adverse-event management of chemotherapy for small-cell lung cancer (SCLC). Sequencing of optimal treatment for SCLC is still a challenge for oncologists. In this paper, we aim to present a different approach to the treatment of SCLC. METHODS: Between January 2008 and July 2014, all patients diagnosed with extensive-stage SCLC and treated with third-line chemotherapy at Gaziantep University Oncology Hospital were analyzed retrospectively. Disease control rates and progression-free survival (PFS) for first-, second-, and third-line chemotherapy, and overall survival (OS) were recorded. Survival analysis was calculated by using Kaplan-Meier method. RESULTS: A total of 255 SCLC patients were screened, and 25 of those patients who received third-line chemotherapy were included in this study. Median age was 57±10.131 years (range: 39-74 years). Disease control rates at first-, second-, and third-line chemotherapy were 92%, 68%, and 44%, respectively. Fourteen patients received irinotecan followed by topotecan, and eleven patients received topotecan followed by irinotecan. Second-line median PFS was statistically better in patients treated with irinotecan at second-line compared with those treated with topotecan (21 vs 12 weeks, P=0.018). Comparison of third-line median PFS of the two groups was not statistically significant (14 vs 12 weeks, P=0.986). Median OS was not statistically significant in patients who received irinotecan followed by topotecan vs those who received topotecan followed by irinotecan (18 vs 14 months, P=0.112). CONCLUSION: Sequential monotherapy with topotecan and irinotecan provides a considerable contribution to OS, and second-line irinotecan showed a better PFS, despite a similar OS, compared with topotecan.

RESUMO

Mammalian Sirtuins have been shown to perform distinct cellular functions and deregulated expression of these genes was reported to be involved in the development of various malignancies including breast cancer. An increasing number of evidence indicates that Sirtuins have both tumor promoter and tumor suppressor functions. However, the roles of Sirtuins have not been well-reported in breast cancer. In the present study, quantitative expression levels of Sirtuins (SIRT1-7) in breast cancer patients and breast cancer cell lines (MCF-7 and SKBR3) and control cell line (CRL-4010) were assessed by using a high-throughput real-time PCR method. As a result, Sirtuins were found to be differentially expressed in breast cancer tissues and cancer cell lines. Particularly, expressions of SIRT1 and SIRT4 were found to be significantly down-regulated in breast cancer tissues and SKBR3 breast cancer cells. In contrast, SIRT2, SIRT3, and SIRT5 genes were shown to be up-regulated in our study. Although SIRT6 and SIRT7 were also up-regulated in breast cancer tissues, these expression changes were statistically insignificant. Additionally, SIRT2, SIRT3, SIRT5, SIRT6 and SIRT7 were found to be differentially expressed in breast cancer cell lines. Yet, these changes were not well-correlated with tissue expression levels. In conclusion, Sirtuin family of genes shows differential expressions in breast cancer tissues and cells and SIRT1 and SIRT4 seem to play key tumor suppressor roles in breast cancer development. Herein, we report expression levels of Sirtuin family of genes in both breast cancer tissues and cancer cell lines simultaneously.

RESUMO

Hepatocellular carcinoma (HCC) and renal cell cancer (RCC) are malignancies, which are chemotherapy resistant and fatal at the advanced stages. Previously developed tyrosine kinase inhibitors are used in the treatment of advanced stage disease. In the present case study, a patient using sunitinib for stage IV RCC presented with HCC following 2 years of treatment. A patient who exhibited Child-Pugh class C cirrhosis initially, exhibited a marked improvement of hepatocellular parenchyma findings following treatment with sunitinib. Sunitinib is suggested to have preventive effects on the pathogenesis of liver fibrosis and cirrhosis in vitro, via an anti-vascular endothelial growth factor and anti-platelet-derived growth factor mechanism. However, no clinical supportive study has been performed until now. Improvement of liver functions may be explained in this manner. Therefore, investigations are required with different doses of sunitinib and other tyrosine kinase inhibitors in order to evaluate the efficacy on treatment of cirrhosis progression.

RESUMO

BACKGROUND: Oxaliplatin and taxane-induced neurosensory toxicity is dose-limiting and mostly presents with acute symptoms that affect the activities of daily living and overall quality of life. The objective of the present study is to assess the relief of acute neuropathy with venlafaxine treatment during the chemotherapy period. PATIENTS AND METHODS: In this retrospective case-control study, from January 2010 to February 2015, patients who experienced treatment with oxaliplatin and taxane-induced acute neurotoxicity were evaluated according to the NCI-CTCAE v. 4.03 grading scale. Neurotoxicity was evaluated using a numeric rating scale (NRS) for pain intensity and experienced relief under the treatment of venlafaxine and using a neuropathic pain symptom inventory scale (NPSI) for the style of complaints. Patients who were diagnosed as mildly depressed according to the HOST anxiety and depression scale and who had grade 1 to 3 sensory neurotoxicity based on the NCI-CTCAE v. 4.03 grading scale, and who also reported ≥ 4/10 on a NRS were eligible. The primary end point was the rate of more than 75 % symptomatic relief under venlafaxine treatment. RESULTS: Two hundred six patients were included (82 % female, median age: 52.7 years). Most patients had breast, gynecologic, and colon cancer (93.4 %). Ninety-one patients who received venlafaxine and 115 patients as the control group were assessed for neurotoxicity every 3 weeks. Based on the NRS, a rate of more than 75 % symptomatic relief was 53.5, 58.3, and 45.2 % in venlafaxine arm versus 0, 0, and 0 % in the control arm in the first, second, and third visits, respectively. Side-effects of venlafaxine (n = 7) were grade 1-2 nausea/vomiting (3.2 %) and asthenia/somnolence (3.2 %) without grade 3-4 events. CONCLUSION: Venlafaxine has a significant clinical activity against taxane-oxaliplatin-induced acute neurosensory toxicity.

RESUMO

PURPOSE: The purpose of this study was to determine whether the presence of diabetes mellitus (DM) influences the incidence and severity of peripheral sensory neuropathy (PSN) in patients using taxane therapy. METHODS: A retrospective single-center analysis was conducted: Patients with PSN at baseline were excluded. The incidence of PSN was evaluated retrospectively in patient subgroups who received taxane arm and taxane-plus-platinum-agents combination arm with or without known DM at baseline. RESULTS: Three hundred seventy-four patients were enrolled in this study, 81 (21.6%) of patients had DM at baseline. The incidence of grade 1 PSN (non-DM/DM) in patients receiving taxane-based chemotherapy was 33.4/25.9% and more than grade 2 PSN (non-DM/DM) was 15/34.6%. The rate of neuropathy of non-diabetic patients was 48.8%, while the rate of diabetic patients was 52.8 and 75% in DM duration below 5 years and above 5 years group, respectively. CONCLUSIONS: This retrospective analysis indicates that taxane-based therapy in DM patients whose disease duration is above 5 years appears to affect the incidence and severity of PSN without known baseline neuropathy. The probability of PSN with taxane-based therapy was similar in DM duration below 5 years and non-DM patients.

RESUMO

Erlotinib, an epidermal growth factor receptor and tyrosine kinase inhibitor, is a targeted drug that was approved for the treatment of non-small-cell lung cancers and pancreatic cancers. Targeted tyrosine kinase inhibitors are known to have cardiotoxic effects. However, erlotinib does not have a statistically proven effect of increasing acute cardiovascular event (ACE) risk. Preclinical studies showed that beta agonist stimulation among rats that were administered erlotinib led to cardiovascular damage. Thus, there would be an aggregate effect of erlotinib on ACE, although it is not thought to be a cardiotoxic drug itself. In this paper, we present two non-small-cell lung cancer cases that developed ACE under erlotinib treatment.

RESUMO

CONTEXT: Cancer is a prothrombotic state and anticancer therapies are often complicated by vascular events. The risk of developing thromboembolic events is substantially increased in patients with pancreatic cancer. One possible presentation of vascular events in pancreatic cancer is disseminated intravascular coagulation (DIC). CASE REPORT: In our case a patient with a diagnosis of pancreatic cancer initially presented with thrombosis and received low molecular weight heparin (LMWH) in addition to standard chemotherapy regimen. He was thought to have DIC by assessment of clinical and laboratory findings. CONCLUSION: Clinically, thrombosis was first located in the left femoral vein and encountered at right femoral artery after three weeks. This pattern was an unusual presentation of DIC. Subclinical DIC is common in patients presenting with pancreatic cancer and is considered a 'poor' prognostic factor. Acute DIC, on the other hand is a potentially mortal condition.

RESUMO

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.

RESUMO

Vitiligo-like lesions, although rare, are believed to be a prognostic factor in malignant melanoma. While a predictive role for such lesions was shown with immunomodulatory therapies, this relation was not demonstrated with temozolomide. We present 3 patients with metastatic malignant melanoma who developed vitiligo-like skin lesions accompanying good response to treatment and prolonged survival. Onset of vitiligo-like lesions with temozolomide in metastatic malignant melanoma may predict long-term response for this treatment.

RESUMO

The present case report defines a rare case of a liposarcoma with bone metastasis resulting in a complete remission (CR) following trabectedin treatment. The patient was referred with abdominal swelling and pain. A retroperitoneal mass was detected and described as dedifferentiated liposarcoma (DDLS). The mass was surgically removed and consequently adjuvant chemotherapy was administered. Three months after the completion of chemotherapy, patient presented with bone metastasis in thoracic and lumbar vertebrae. Vertebroplasty and radiotherapy (RT) was performed. After these therapies, bone pain persisted and bone scintigraphy showed increased activity in L4, T11, and T12 vertebrae. Zoledronic acid was added to trabectedin treatment. CR has been detected on bone scintigraphy and positron emission tomography-computed tomography (PET-CT) after 18 weeks. Previous cases about liposarcoma treated with trabectedin were mostly about the myxoid/round cell type (former name, currently known as myxoid liposarcoma (MLS)) and mostly reported partial responses. In this study, trabectedin was used for the treatment of a metastatic retroperitoneal DDLS and a CR was achieved.

RESUMO

PURPOSE: To investigate whether the initial maximum standardized uptake value (SUVmax) on fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) has a prognostic significance in metastatic lung adenocarcinoma. PATIENTS AND METHODS: Sixty patients (24 females, mean age: 57.9±12 years) with metastatic stage lung adenocarcinoma who used erlotinib and underwent (18)F-FDG PET/CT at the time of diagnosis between May 2010 and May 2014 were enrolled in this retrospective study. The patients were stratified according to the median SUVmax value, which was found as 11. Progression-free survival (PFS) rates for 3, 6, and 12 months were examined for SUVmax values and epidermal growth factor receptor (EGFR) mutation status. RESULTS: The number of EGFR-sensitizing mutation positive/negative/unknown was 26/17/17, respectively, and the number of patients using erlotinib at first-line, second-line, and third-line therapy was 15, 31, and 14 consecutively. The PFS rates of EGFR mutation positive, negative, and unknown patients for 3 months were 73.1%, 35.3%, and 41.2% (P=0.026, odds ratio [OR]=4.39; 95% confidence interval [CI]: 1.45-13.26), respectively. The PFS rates of EGFR positive, negative, and unknown patients for 6 months were 50%, 29.4%, and 29.4% (P=0.267, OR: 2.4; 95% CI: 0.82-6.96), respectively. The PFS rates of EGFR positive, negative, and unknown patients for 12 months were 42.3%, 29.4%, 23.5% (P=0.408, OR: 2.0; 95% CI: 0.42-5.26), respectively. Thirty-one of 60 patients had SUVmax values ≤11. The PFS rates for 3, 6, and 12 months were 70.5%/28% (P=0.001, OR=9.0; 95% CI: 2.79-29.04), 61.7%/8% (P<0.001, OR=28.35; 95% CI: 5.5-143), and 52.9%/8% (P<0.001, OR=18.69; 95% CI: 3.76-92.9) for low SUVmax (≤11) group/high SUVmax (>11) group, respectively. CONCLUSION: Initial SUVmax value on (18)F-FDG PET/CT is found to be a prognostic factor anticipating the response to erlotinib for 3, 6, and 12-month rates of PFS in both EGFR-sensitizing mutation and wild-type tumor group.

RESUMO

BACKGROUND: Urotensin II is a vasoactive polypeptide. It is known that some vasoactive polypeptides are produced and secreted by tumor cells, and act as a paracrine growth stimulant. The aim of this study was to examine the relationship between urotensin II and its receptor's messenger RNA expression in breast cancer. MATERIAL/METHODS: Fifty-nine women with breast cancer were included in this study. The median age was 48 years. The relationships between urotensin II and urotensin II receptor mRNA expressions, which were derived from fresh breast cancer tissues and adjacent normal breast tissues, and clinical and pathological parameters, were assessed. RESULTS: We found expressions of urotensin II mRNA and its receptor in 55 of 59 breast cancer tissues and in 55 of 59 normal breast tissues. We found a positive significant correlation between urotensin II and its receptor (p=0.001, r=0.632), and found a negative, but insignificant, correlation between urotensin II and age (p=0.038, r=-0.281). Urotensin II levels were higher in the premenopausal group compared to the postmenopausal group (p<0.05). The mean urotensin II receptor expression was higher in the premenopausal group (p<0.05) compared to the postmenopausal group, and its expression was also higher in the group without extra-nodal invasion compared to that of the group with extra-nodal invasion (p=0.001). Urotensin II levels were higher in the group without lymphatic invasion compared to the group with lymphatic invasion (p=0.048). CONCLUSIONS: This study is the first in the English medical literature to determine the urotensin II and its receptor mRNA expressions in breast cancer tissues. Consequently, urotensin II seems be associated with menopausal status, and extra-nodal and lymphatic invasion.

RESUMO

Gastric cancer is one of most common types of cancers. Metastatic gastric cancer has a poor prognosis and is accepted as incurable at this stage. Treatment of metastatic gastric cancer did not progress substantially until new targeted agents have come out. Recently published ToGA trial showed promising results in HER2 overexpressing metastatic gastric cancer. In this case we present a case with an excellent complete response with anti-HER2 treatment. Most importantly, we wanted to emphasize (1) the importance of early determination of HER2 overexpression, and (2) to draw attention of anti-HER2 agents in the first line treatment even in patients with a poor performance status.

RESUMO

Stiff person syndrome (SPS) is a rare condition that causes rigidity in the muscles of the body and extremities, difficulty in walking, episodic spasms and progressive disability. SPS is generally seen together with autoimmune disorders such as diabetes mellitus, thyroiditis, vitiligo and pernicious anaemia. Rarely, it may develop as a paraneoplastic condition. SPS cases associated with breast cancer, small cell lung carcinoma, thymoma, Hodgkin's lymphoma and colorectal cancer have been reported in the literature. We present a case of a 58-year-old female patient who had malignant mesothelioma-associated SPS. Patients who have muscle spasms and difficulty in movement of joints should be evaluated for SPS before diagnosis of Parkinson's or other neurological disorders, and possible underlying malignancies should be excluded.

RESUMO

BACKGROUND AND AIM: Breast cancer is the most common type of cancer amongst women today. The aim of this study was to examine the association between complementary and alternative medicine (CAM) and the quality of life (QoL), anxiety and depression and demographic characteristics of women with breast cancer. MATERIALS AND METHODS: QoL was measured by the European Organization for Treatment and Research of Cancer quality of life core questionnaire (QLQ-C30, version 3.0) and anxiety and depression was measured by the hospital anxiety and depression scale. RESULTS: In total, 122 patients with breast cancer were enrolled in the study and 50% (n=61) of them reported that they were using CAM. The most commonly used CAM methods were stinging nettle (57%) and prayer and spiritual healing (49%). No relationship was found between the use of CAM and the patient's age, time to diagnosis, cancer stage, chemotherapy use, smoking and residence. However, the analyses showed a positive association between CAM and role functioning (P=0.014) and financial difficulties (P=0.011); and a negative association between CAM and emotional functioning (P=0.033). CONCLUSIONS: Based on the previous studies, 20-83.3% of breast cancer patients among different countries and cultures used CAM. Our results suggested that the use of CAM among women is quite popular, but they showed no correlation between CAM usage and anxiety and depression. In addition, CAM usage was more common in breast cancer patients with a poor emotional and financial status.

RESUMO

Glioblastoma multiforme (GBM) is the most common and the most aggressive primary malignant tumor of the brain. Prognostic factors in GBM can be sorted as age, tumor localization, tumor diameter, symptom period and type, the extent of surgery, postoperative tumor volume, and adjuvant radiotherapy and/or chemotherapy status. Besides the interactions between actin microfilaments, microtubules, and intermediate filaments, environmental factors and intracellular signals which regulate them affect the cell invasion. Rho proteins and therefore Rho-kinase activation play important role at these changes. The aim of this study is to evaluate the relationship between the Rho-kinase pathway gene expressions and prognosis in GBM. Ninety-eight patients diagnosed as GBM between 2001 and 2010 were enrolled into the study. RNA was obtained from the paraffinized tumor tissue of the patients with formalin-fixed, paraffin-embedded RNA isolation kit and the mRNA expressions of 26 genes were investigated. There was a statistically significant negative correlation between the ages at the diagnosis and survival. There was a significant relationship between the overexpression of Rho-kinase pathway-related genes LIMK1, CFL1, CFL2, and BCL2 and low expression of MAPK1 gene and the survival of the patients. These results demonstrate for the first time that there is a marked contribution of Rho-kinase pathway-related genes to the progression and survival of the GBM. The expression of these genes may be related to response of multimodal therapy or these parameters could be used to determine possible unresponsive patients before treatment.
