Perspective of turkish medicine students on cancer, cancer treatments, palliative care, and oncologists (ares study): A study of the palliative care working committee of the turkish oncology group (TOG)

Cancer is one of the most common causes of death all over the World (Rahib et al. in Cancer Res 74(11):2913–2921, 2014; Silbermann et al. in Ann Oncol 23(Suppl 3):iii15–iii28, 2012). It is crucial to diagnose this disease early by effective screening methods and also it is very important to acknowledge the community on various aspects of this disease such as the treatment methods and palliative care. Not only the oncologists but every medical doctor should be educated well in dealing with cancer patients. Previous studies suggested various opinions on the level of oncology education in medical schools (Pavlidis et al. in Ann Oncol 16(5):840–841, 2005). In this study, the perspectives of medical students on cancer, its treatment, palliative care, and the oncologists were analyzed in relation to their educational status. A multicenter survey analysis was performed on a total of 4224 medical school students that accepted to enter this study in Turkey. After the questions about the demographical characteristics of the students, their perspectives on the definition, diagnosis, screening, and treatment methods of cancer and their way of understanding metastatic disease as well as palliative care were analyzed. The questionnaire includes questions with answers and a scoring system of Likert type 5 (absolutely disagree = 1, completely agree = 5). In the last part of the questionnaire, there were some words to detect what the words “cancer” and “oncologist” meant for the students. The participant students were analyzed in two study groups; “group 1” (n = 1.255) were phases I and II students that had never attended an oncology lesson, and “group 2” (n = 2.969) were phases III to VI students that had attended oncology lessons in the medical school. SPSS v17 was used for the database and statistical analyses. A value of p < 0.05 was noted as statistically significant. Group 1 defined cancer as a contagious disease (p = 0.00025), they believed that early diagnosis was never possible (p = 0.042), all people with a diagnosis of cancer would certainly die (p = 0.044), and chemotherapy was not successful in a metastatic disease (p = 0.003) as compared to group 2. The rate of the students that believed gastric cancer screening was a part of the national screening policy was significantly more in group 1 than in group 2 (p = 0.00014). Group 2 had a higher anxiety level for themselves or their family members to become a cancer patient. Most of the students in both groups defined medical oncologists as warriors (57% in group 1 and 40% in group 2; p = 0.097), and cancer was reminding them of “death” (54% in group 1 and 48% in group 2; p = 0.102). This study suggested that oncology education was useful for the students’ understanding of cancer and related issues; however, the level of oncology education should be improved in medical schools in Turkey. This would be helpful for medical doctors to cope with many aspects of cancer as a major health care problem in this country. © 2018, American Association for Cancer Education

NF-KappaB expression correlates with apoptosis and angiogenesis in clear cell renal cell carcinoma tissues

<p>Abstract</p> <p>Background</p> <p>Clear cell renal cell carcinoma (ccRCC) is the most frequently encountered tumor in the adult kidney. Many factors are known to take part in the development and progression of this tumor. Nuclear factor kappa B (NF-κB) is a family of the genes that includes five members acting in events such as inflammation and apoptosis. In this study, the role of NF-κB (p50 subunit) in ccRCC and its relation to angiogenesis and apoptosis were investigated.</p> <p>Methods</p> <p>Formalin-fixed and paraffin embedded tissue blocks from 40 patients with ccRCC were studied. Expressions of NF-κB (p50), VEGF, EGFR, bc1-2 and p53 were detected immunohistochemically. The relationship of NF-κB with these markers and clinicopathological findings were evaluated.</p> <p>Results</p> <p>The expression of NF-κB was detected in 35 (85%), VEGF in 37 (92.5%), EGFR in 38 (95%), bc1-2 in 33 (82.5%) and p53 in 13 (32.5%) of 40 ccRCC patients. Statistical analyses revealed a significant relation between NF-κB expression and VEGF (p = 0.001), EGFR (p = 0.004), bc1-2 (p = 0.010) and p53 (p = 0.037). There was no significant correlation between NF-κB and such parameters as tumor grade, stage, age and sex.</p> <p>Conclusion</p> <p>The results of this study indicated that in ccRCC cases NF-κB was associated with markers of angiogenesis and apoptosis such as VEGF, EGFR, bc1-2 and p53. In addition, the results did not only suggest a close relationship between NF-κB and VEGF, EGFR, bc1-2 and p53 in ccRCC, but also indicate that NF-κB was a potential therapeutic target in the treatment of ccRCC resistant to chemotherapy.</p

Cancer therapy and cardiotoxicity: The need of serial Doppler echocardiography

Cancer therapy has shown terrific progress leading to important reduction of morbidity and mortality of several kinds of cancer. The therapeutic management of oncologic patients includes combinations of drugs, radiation therapy and surgery. Many of these therapies produce adverse cardiovascular complications which may negatively affect both the quality of life and the prognosis. For several years the most common noninvasive method of monitoring cardiotoxicity has been represented by radionuclide ventriculography while other tests as effort EKG and stress myocardial perfusion imaging may detect ischemic complications, and 24-hour Holter monitoring unmask suspected arrhythmias. Also biomarkers such as troponine I and T and B-type natriuretic peptide may be useful for early detection of cardiotoxicity. Today, the widely used non-invasive method of monitoring cardiotoxicity of cancer therapy is, however, represented by Doppler-echocardiography which allows to identify the main forms of cardiac complications of cancer therapy: left ventricular (systolic and diastolic) dysfunction, valve heart disease, pericarditis and pericardial effusion, carotid artery lesions. Advanced ultrasound tools, as Integrated Backscatter and Tissue Doppler, but also simple ultrasound detection of "lung comet" on the anterior and lateral chest can be helpful for early, subclinical diagnosis of cardiac involvement. Serial Doppler echocardiographic evaluation has to be encouraged in the oncologic patients, before, during and even late after therapy completion. This is crucial when using anthracyclines, which have early but, most importantly, late, cumulative cardiac toxicity. The echocardiographic monitoring appears even indispensable after radiation therapy, whose detrimental effects may appear several years after the end of irradiation

Pretreatment serum albumin level is an independent prognostic factor in patients with stage IIIB non-small cell lung cancer: A study of the Turkish descriptive oncological researches group

PubMed ID: 26320482Background: Several prognostic factors have been studied in NSCLC, although it is unknown which is most useful. In this study, we aimed to investigate whether pre-treatment serum albumin level has prognostic value in patients with Stage IIIB NSCLC. Materials and Methods: This cross-sectional study included a total of 204 patients with Stage IIIB NSCLC who met the inclusion criteria. Pre-treatment serum albumin levels and demographic, clinical, and histological characteristics, as well as laboratory variables were recorded. A cut-off value was defined for serum albumin level and the patients were stratified into four groups on thios basis. Results: The majority of the patients was males and smokers, with a history of weight loss, and squamous histological type of lung cancer. The mean serum albumin level was 3.2±1.7 g/dL (range, 2.11-4.36 g/dL). A cut-off value 3.11 g/dL was set and among the patients with a lower level, 68% had adenocarcinoma and 82% were smokers. The patients with low serum albumin levels had a lower response rate to e first-line chemotherapy with a shorter progression-free survival and overall survival. Multivariate analysis showed that low serum albumin level was an independent poor prognostic factor for NSCLC. Conclusions: This study results suggest that low serum albumin level is an independent poor prognostic factor in patients with Stage IIIB NSCLC, associated with reduction in the response rate to first-line therapy and survival rates

Treatment of malignant insulinoma with fluocortolone and high-dose folinic acid and 5-fluorouracil: Case report and review of the literature

Insulinoma is a rare islet cell tumor with typical clinical and biochemical characteristics caused by excessive insulin secretion. The malignant form is characterized by metastases for which a curative resection is rarely possible. Chemotherapy is usually ineffective. We achieved control of serum glucose levels with fluocortolone in a patient with malignant insulinoma and hypoglycemia. We then administered high dose folinic acid and 5-fluorouracil (5-FU) bolus, then 5-FU by continuous in, fusion for 2 consecutive days every 2 weeks (this method is abbreviated as HDLV5FU). The plasma insulin and C-peptide levels remained unchanged and the neoplasm was stable for 4 months with this therapy. According to the authors' literature review, this is the first malignant insulinoma case treated with both fluocortolone and HDLV5FU. Prospective studies are needed to determine more effective treatment modalities for malignant insulinoma

Cardiotoxicity of de Gramont's regimen: Incidence, clinical characteristics and long-term follow-up

Background: The incidence of 5-fluorouracil (5-FU)-related cardiotoxicity seems to be dosage and schedule dependent. It was reported as 1.6-3% with earlier bolus regimens whereas this increased up to 7.6-18% with prolonged (4-5 days) infusion regimens. Knowledge of the cardiotoxicity incidence in patients treated with the widely used de Gramont's regimen (2 days infusional 5-FU) and the long-term follow-up of affected patients is still limited

Role of increased mean platelet volume (MPV) and decreased MPV/platelet count ratio as poor prognostic factors in lung cancer

Objectives: In this study, they investigated whether mean thrombocyte volume (MPV) and MPV/platelet count ratio have a prognostic significance in advanced NSCLC or not. Methods: A total of 496 NSCLC patients at stage IIIB/IV and did not meet exclusion criteria were included in the study. The demographic features (age, gender, smoking habit), clinical characteristics (performance status, weight loss, disease stage, first-line treatment regimen), laboratory tests (levels of hemoglobin, lactate dehydrogenase and calcium as well as MPV, MPV/platelet count ratio and counts of white blood cell, platelet), and histological features (histologic type, tumor grade) were recorded. Results: The MPV levels of all patients were determined as 10.2 {plus minus} 3.4 (range, 6.4-14.1 fL). With ROC curve analysis, the MPV/PC ratio was associated with a sensitivity of 67.8% and a specificity of 84.8% at a cutoff value of 0.47424 for presence of brain metastasis at the time of diagnosis. Univariate analysis showed that OS was significantly shorter in the group with an increased MPV level than in the other group (median OS time 6.8 months vs. 11.5 months, log-rank, P =.032). Multivariate analysis confirmed that an increased MPV level was an independent poor prognostic factor for OS (HR: 1.704, 95% CI: 1.274-3.415, P =.014). Conclusions: Unlike results of previous studies, the study showed that increased MPV was an important prognostic factor in patients with NSCLC. Hence, an increased MPV level may be used as a prognostic biomarker to estimate for poor overall survival in patients with NSCLC. © 2017 John Wiley & Sons Lt
