Article Enhancement of Paclitaxel Therapeutic Effect by Aptamer Targeted Delivery in Plga Nanoparticles(2021) Dursun, Ali; Dursun, Ali Doğan; Ucak, Samet; Özalp, Veli Cengiz; Poyraz, Fatma Sayan; Yilmaz, Elif; Mansuroglu, Banu; Ozalp, Veli Cengiz; Dursun, Ali Doğan; Özalp, Veli Cengiz; Basic Sciences; Basic SciencesObjectives: Paclitaxel is a drug molecule used in the therapy of various cancer types, including breast cancer. It is one of the preferred chemotherapy agent due to its high efficacy. However, many side effects have been observed associ- ated with paclitaxel use such as allergy, hair loss, diarrhea and pain. Methods: We evaluated therapeutic efficacy of paclitaxel when it is actively targeted to breast cancer tumours inside a polymeric nanoparticle. Targeted delivery of paclitaxel to tumour sites has been reported as an improved cytotoxicity strategy with a variety of nanoparticles. In this study, poly Lactic-co-Glycolic Acid (PLGA) nanoparticles were used as drug carrier and nucleolin aptamers as affinity targeting agents. Results: Paclitaxel molecules were entrapped during the synthesis of PLGA nanoparticles of 238 nm in diameter. The encapsulation and loading efficiencies of paclitaxel was 97% and 21% respectively. The paclitaxel loaded PLGA nanoparticles were functionalized with nucleolin aptamers and their targeting ability to cultured mouse cancer cells was determined for two cell lines (E0771 and 4T1). E0771 cell line was chosen for the preparation of allograph breast cancer mouse models. Evaluations of the targeted paclitaxel in PLGA nanoparticles showed 38% better performance in inhibiting tumour growth compared to free paclitaxel treatment groups of mouse models. Conclusion: The chemotherapeutic effect of cancer drugs like paclitaxel can be increased by loading inside tumour targeted polymeric nanoparticlesArticle Herpes Zoster Hastalarının Demografik ve Klinik Özelliklerinin Değerlendirilmesi(Selcuk University, 2023) Demirci Saadet, E.; Hasanbeyzade, S.; Hasanbeyzade, Sabir; Saadet, Elif DemırcıBackground: Herpes zoster is a disease that is more frequently seen in people aged over 50 years and negatively affects the quality of life due to the development of post-herpetic neuralgia. This study aimed to investigate the demographic and clinical characteristics of patients diagnosed with herpes zoster. Methods: In this cross-sectional study, the data of patients who were followed up with a diagnosis of herpes zoster at the dermatology department between 2013 and 2020 were retrospectively examined. Results: Of 440 patients, 252 (57.3%) were female and 188 (42.7%) were male. The mean age was 48.9±18 (4-94) years. The most common localization was the thoracic region at a rate of 35.5% and the lumbar region at a rate of 21.4%. Disseminated and ophthalmic zoster were more common in elderly patients (p<0.001). The most common comorbidities were hypertension (HT)+coronary artery disease (CAD) (12.6%), cancer (10.3%), and diabetes+HT (5.9%). Severe pain was observed in 19.7% of the patients and was more common in women (p=0.016). The rate of moderate and severe pain was high in the patients with HT+CAD and cancer (p˂0.001). Post-herpetic neuralgia was observed in 15.3% of the patients aged over 50. Conclusions: Herpes zoster is especially common in adults. Since it causes acute pain and can lead to postherpetic neuralgia development, risky patient groups should be more carefully followed up and treated. © 2023, Selcuk University.

FIN-PED II was translated into Turkish and then back-translated and then evaluated by three experts for face validity. For construct validity, exploratory factor analysis was applied andfor reliability, internal consistency analysis was employed.RESULTSAs a result of exploratory factor analysis, it was observed that percentages of explaining total variancewere 74.787%, 68.649%, and 72.746% for sections of the importance of care needs, the need fulfilment,and the need for further information, respectively. As a result of Cronbach’s Alpha reliability analysis,the reliabilities of the sections on the importance of care needs, need fulfilment, and the need for furtherinformation for FIN-PED II was 0.814, 0.906, and 0.915.CONCLUSIONAlthough the Turkish version of FIN-PED II needs further psychometric testing, it is an effective, validand reliable tool to find out the care needs of parents of children with cancer.Article Citation - WoS: 2Citation - Scopus: 2Role of Surveillance Screening in Detecting Tumor Recurrence After Treatment of Childhood Cancers(Aves, 2021) Kısa, Pelin Teke; Emir, Suna; Teke Kısa, PelinObjective: As the survival rates in children with cancer reach up to 80%, this improvement in survival increases the number of patients under follow-up. After cancer treatment is completed, patients are taken to follow-up surveillance to ensure the early detection of recurrence and the late effects of treatments. The frequency and necessity of surveillance screening tests are controversial. This study aimed to assess the efficacy of surveillance screening in the detection of recurrence. Material and methods: The files of 533 children who were diagnosed as having cancer at our pediatric oncology clinic between 2004 and 2013 were retrospectively evaluated. We looked at outcomes after recurrence, the timing and pattern of recurrence, the presence of symptoms during recurrence, physical examination findings, tumor marker levels, laboratory findings, and radiologic tests. Results: Of the 63 patients with recurrence, 23 were symptomatic and 40 were asymptomatic at the time of the recurrence. Tumor location and time of the recurrence did not affect the post recurrence survival. The median post-recurrence survival for patients was 13 (range, 1-98) months. The median post-relapse survival was 10 (range, 1-73) months in patients with symp-tomatic recurrence, and 16 (range, 1-98) months in patients with asymptomatic recurrence. It was determined that patients in whom recurrence was identified with surveillance tests had longer post-relapse survival time. The 5-year survival rate of 23 patients with symptomatic recurrence was 12.2%; this rate was 49.5% in asymptomatic patients (p<0.05).Conclusions: It should be considered that surveillance testing offers the benefit of prolonging post recurrence survival.Article Citation - WoS: 14Citation - Scopus: 12The Randomized Controlled Study of Low-Level Laser Therapy, Kinesio-Taping and Manual Lymphatic Drainage in Patients With Stage Ii Breast Cancer-Related Lymphedema(Galenos Publ House, 2023) Yılmaz, Sedef Selçuk; Ayhan, Fikriye FigenObjective: To compare the effects of low-level laser therapy, kinesio-taping and manual lymphatic drainage (MLD) on the affected arm volume, quality of life, arm function, neuropathic pain and shoulder mobility in patients with stage II breast cancer-related lymphedema. Materials and Methods: Forty-five breast cancer patients with stage II lymphedema were included. The patients were randomized to three groups and treated with MLD, kinesio-taping or low-level laser therapy. After these different therapeutic modalities, all patients received multilayer compression bandaging, lymphedema remedial exercises, skin care, and a patient education program by the same lymphedema therapist. All treatments were applied 5-days a week for three weeks. The lymphedema compression garments were prescribed to all patients and follow-up visits were planned at the end of the treatment, and at four and 12 weeks. The efficacy of the treatments was evaluated by volumetric calculations based on circumferential measurements using the formula for a truncated cone, in addition to goniometric assessments for shoulder joint ROM, and questionnaires: Quick-disability of arm, shoulder and hand for arm disability; pain-detect for neuropathic pain; and quality of life for arm lymphedema (LYMQOL-arm). Results: The baseline patient and disease characteristics, and outcome measures were similar between groups. All treatment modalities were found to be effective in decreasing arm volume, and improving quality of life, upper extremity disability and neuropathic pain. The percentage of decreased arm volume or treatment success was better in kinesio-taping group than in the MLD group at the end of the treatment, and at four and 12 weeks after treatment (p = 0.009, p = 0.039, and p = 0.042, respectively). Conclusion: Kinesio-taping led to better results than MLD and was similarly effective compared with low-level laser in stage II breast cancer-related lymphedema at the twelfth week of follow-up. Kinesio-taping and low-level laser should be considered as alternative treatments in early-moderate stages of lymphedema. After these modalities, multi-layer compression and compression bandaging remain cornerstones of lymphedema treatment.Article Efficacy of Gamma-Knife Radiosurgery in Grade 2 and Grade 3meningioma: a Single-Center, Long-Term Follow-Up Study(2021) Bulduk, Erkut Baha; Demirci, Harun; Karaaslan, Burak; Demirtaş, Oğuz Kağan; Emmez, Ömer Hakan; Kurt, GökhanObjectives: Gamma-Knife Radiosurgery (GKR) is a safe and effective treatment option in patients who have a high riskof complications in skull base and eloquent area-based tumors, in those to whom total surgery cannot be applied. Thepurpose was to analyze the results of radiosurgery in patients who underwent GKR for the residues or recurrent tumorsin high grade meningiomas. Methods: A retrospective screening was performed on patients who underwent GKR at Gazi University between 2004and 2018. The gender, mean age, location, volume, complications, size changes after GKR were noted. Results: A total of 35 (79.5%) patients were treated with Grade 2, and 9 (20.5%) were treated with Grade 3 meningio mas. The mean follow-up period was 48 months (3-108). The mean volume was noted as 9339 mm3 . The tumor controlrates after GKR were determined as 94% in Grade 2 and 55% in Grade 3 meningiomas. Conclusion: GKR can be applied as a safe and effective method for postoperative tumor control in high grade meningiomas.Article Effects of Total and Subtotal Glial Tumor Resection on Survival(2020) Ercan, Serdar; Ataizi, Zeki S; Ataizi, Fulya; Bulduk, Erkut BahaObjectives: Glial tumors are treated with a multidisciplinary team approach including specialists in brain surgery, radiology, pathology, radiation oncology and medical oncology. Surgery is one of the main treatment options. However,the effect of resection volume on prognosis is still uncertain. The aim of this study is to investigate the relationshipbetween the residual tumor volume and survival of the patients who were operated with the diagnosis of intracranialglial tumor in the last 5 years.Methods: Of 49 patients, 30 underwent total resection and 19 underwent subtotal resection.Results: The average surveys of total resection were 13.6 (6-32 months) months. 4 of 6 patients with anaplastic astrocytoma survived and the mean survey was 26.5 (4-45) months. The survey of subtotal resection group was significantlyshorter than the other TR group.Conclusion: As a result, recovery was inversely increased with residual tumor volumeArticle Retrospective Evaluation of Childhood Central Nervous System Tumors Followed in a Pediatric Hematology Oncology Center: a Single Center Experience(Akad Doktorlar Yayinevi, 2024) Erdem, Arzu Yazal; Emır, Suna; Özyörük, Derya; Genç, Aslı; Yazal Erdem, ArzuCentral nervous system (CNS) tumors are one of the main causes of cancer-related deaths in childhood. Although approximately 60% of all patients are alive 5 years after diagnosis, a sequela due to the disease and treatments are common. In this study, we aimed to evaluate the demographic, clinical characteristics, and outcomes of the childhood CNS tumors in our center. A total of 141 patients between 0-18 years who were followed up and completed their treatment in our pediatric oncology center were included. The files were reviewed retrospectively. The median age of patients was 7 years (range 1 month-17.6 years). The male/female ratio was 1.1: 1. The most common presenting symptom was headache. The median time from the first symptom to diagnosis was 1.4 months. Medulloblastoma was the most common diagnosis (n= 28, 19.9%), followed by pilocytic astrocytoma (18.4%, n= 26) respectively. Out of 141 patients, a sequela was seen in 55 (39%) patients. The relationship between high-dose radiotherapy and the development of short stature was statistically significant (p= 0.009). The patients with metastatic disease were likely to have lower survival rates than nonmetastatic disease (p= 0.001). The presence of metastasis increased the death status 6.482 times (OR: 6,482, p= 0.001). The overall 5-year survival rate of all patients was found 80%. There was an association between the histopathological subtypes and overall survival rates (p= 0.001). In the multivariate analysis, metastasis was the most important factor in survival. According to Cox regression analysis, the two most important factors affecting overall survival were the histopathological subtype and the presence of metastasis.Article Factors Affecting the Burden and Quality of Life of Caregivers For\rgynecological Cancer Patients(AVES, 2022) Yaşar, Beril Nisa; Terzioğlu, FüsunObjective: The aim of this study is to evaluate the care burden and quality of life of caregivers of patients with gynecologic cancer.\rMaterial and Methods: This descriptive study was conducted with 251 individuals who provided care to patients with gynecologic cancer in gynecologic oncology\rservices of a university hospital and a state oncology hospital. The data were collected by a semi-structured questionnaire form, Caregiver Burden Inventory (CBI),\rand Quality of Life Family Version.\rResults: The mean age of the participants was 39.76 ± 14.20; 79.3% of them were female, 65.3% were married, 28.7% were high school graduates, 57.4% were\remployed and 56.2% were unemployed before starting care, 91.2% had health insurance, 58.6% perceived their income as moderate, and 57% had relatives of the\rpatient receiving care. Care burden was statistically significant in terms of gender, marital status, educational level, and degree of affinity with the patient (P < .005).\rThe correlation between caregivers’ quality of life, gender, health insurance, income status, and the degree of affinity with the patient was statistically significant\r(P < .005).\rConclusion: As a result of this study, it was determined that some socio-demographic characteristics of the caregivers of patients with gynecologic cancer affected\rthe care burden and quality of life.
