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.

Introduction: Langerhans' cell histiocytosis (LCH) is a proliferative disorder of Langerhans cells, which is seen extremely rarely in adults. Conventional imaging modalities, such as skeletal surveys and bone scans, were accepted to be standard methods for diagnosis; however, 18-fluorodeoxyglucose positron emission tomography (PET-CT) has been increasingly used., Methods: We report on a 33-year-old female patient with disseminated LCH treated with radiotherapy and systemic chemotherapy where PET-CT has been used for defining the extent of the disease, RT planning and assessment of treatment response during follow-up., Results: The patient was treated with 24 Gy 3-dimensional conformal radiotherapy (RT), given as 2 Gy a day, 5 days a week. The patient was also treated with systemic prednisolone 20 mg/m(2), concurrently. The chemotherapeutic regimen switched to cytosine-arabinoside with a dose of 100 mg/m(2) subcutaneously daily for 4 days, vincristine 1.5 mg/m(2) given on the 1st day and prednisolone 20 mg/m(2) for 4 cycles. After local RT with adjuvant chemotherapy, the patient was alive for 54 months and remained disease-free at last visit., Conclusion: RT is a treatment choice in multi-system LCH as well as solitary lesions. Low-dose RT is adequate to control large masses of LCH including soft tissue and lymph nodes.

The aim of our study was to determine the perspective of non-oncologist physicians regarding their attitudes and beliefs associated with palliative care for patients with metastatic cancer. The study was planned as a cross-sectional survey, and non-oncologist physicians were reached via e-mail and social networking sites. The first part of the questionnaire involved demographic properties, the second part inquired as to the perspectives of participants regarding metastatic disease, and the third part was used to determine beliefs and attitudes about palliative care. All of the questions were five-point Likert-type questions. A total of 1734 physicians completed the questionnaire. The majority of participants were general surgeons or internal medicine specialists (21 and 18%, respectively), were male (61%), were younger than 50 years of age (54%), worked in the town center (67%), had more than 11 years of professional experience (57%), and worked in a hospital without an active oncology service (86%). A total of 71% of participants identified all patients with metastatic cancer as being terminal stage, 62% were unaware of palliative care techniques, 64% did not know about common supportive care options, 59% were against hospice, and 63% had no opinion on resuscitation. We determined that non-oncologist physicians believed that all patients with metastatic cancer are at the terminal stage and that palliative/supportive care is the oncologist's task. These data suggest that non-oncologist physicians would benefit from additional graduate and postgraduate courses on these topics.

Defensive medicine occasionally indulges unnecessary treatment requests to defend against lawsuits for medical errors and the use of unapproved medical applications. This study determines the attitudes and orientations of medical oncologists on defensive medicine. A cross-sectional survey was sent by e-mail to medical oncologists. The survey was designed to determine the participants' demographic characteristics and defensive medicine practices. The survey measured the attitudes about defensive medicine practices of the oncologists based on a five-point Likert scale (never, rarely, sometimes, often, and always). One hundred and forty-six of a total of 402 physicians serving in oncology were fully filled, and the rate of return invitation was 36 %. The majority of participants were male, with a duration of between 7 and 9 years of work as university hospital officials, and the mean age was 46 ± 9 (years). International guidelines were followed in the most common is NCCN, and the majority of respondents felt that the application of these guidelines improves their defensive medicine. All participants of defensive medicine who stand on the basis of the definition were found to be more afraid of complaints by patients' relatives. Physicians of 45 % was noted that applying defensive medicine. Among the participants were the most frequent checkups of positive defensive approach is defined as increasing or shortening the follow-up period, while avoiding high-risk patients were detected as described in the definition of negative defensive medicine. Both professional groups in both the positive and negative defensive medicine approach defensive medicine approach, academic tasks, work experience and job time, there was a significant correlation between the location. Made in single- and multi-variable analyses, positions were identified both positive and negative defensive medicine is an independent risk factor for direction. Improving the working conditions of young physicians to protect against medical error may require additional educational opportunities.

The relationship between thyroid disease and cancer (and cancer therapies) has been under investigation for years. Factors that increase the risk for thyroid disease include iodine deficiency, autoimmune disorders, old age, and pregnancy. The screening policy for thyroid disease in the healthy population is not precisely defined, and the frequency of thyroid dysfunction in untreated cancer patients has not been investigated in any great detail. This study was designed to compare the prevalence of thyroid dysfunction in 457 untreated cancer patients at the time of initial diagnosis to that of 373 age- and sex-matched subjects who were healthy and cancer-free (control group). Thyroid dysfunction was found in 29.5 % (135/457) of the cancer patients, while only 15.4 % (56/373) of the control group had thyroid dysfunction (p = 0.0001). The most prevalent abnormality was euthyroid sick syndrome (14.0 %, 64/457). Overt and subclinical hyperthyroidism and overt hypothyroidism were observed more frequently in cancer patients than the control group, and these differences were all statistically significant. Thyroid dysfunction was more frequent in patients with poor performance scores and those over the age of 50 years. These data indicate that alterations in thyroid hormone metabolism are twice as common in patients with untreated cancer than in control subjects. Those alterations may lead to delayed diagnosis, suboptimal treatment, and a poorer prognosis. In all, this study suggests that screening with thyroid function tests is strongly recommended in all newly diagnosed cancer patients.
