    (Asian Pacific Organization for Cancer Prevention, 2011) Goker A.; Guvenal T.; Yanikkerem E.; Turhan A.; Koyuncu F.M.
    Aim: The management of gynecological cancer patients mainly aims at prolonging survival but modern therapy focuses on good survival combined with a good quality of life (QoL). The aim of this study was to evaluate QoL and identify its associated factors in Turkish women with gynecologic cancer. Method: The study included 119 women diagnosed with endometrial, cervical, ovarian or vulvar cancer and treated at the Gynecologic Oncology Department of Celal Bayar University Faculty of Medicine. The data were collected between January and June 2011. QoL was measured with EORTC QLQ-C30 version 3.0. Relationships between clinical and socio-demographic characteristics and QoL scores were analyzed using the Mann-Whitney U, Kruskal Wallis and t-tests. Result: Global health status, physical and role function scores were found higher in women under the age of 60 years. Role function scores were found lower, and emotional and social scores were found to be higher in single women than in married women. Physical scores were found higher in women who had graduated from secondary school or above. Women with ovarian cancer had the highest while women with cervical cancer had the lowest global health score (65.3 ±24.7 and 43.0±24.1, respectively). Women with endometrial cancer were found to have better role function, and social well being than those with vulvar, cervical or ovarian cancer. Global, physical, role function, cognitive and social scores were found higher in women who had been treated with surgery. Conclusion: Gynecological cancer and treatment processes cause significant problems that have negative effects on physical, emotional, social and role function aspects of QoL. Health care providers play a key role in the identification and treatment of the complications of cancer therapy. Minimizing the effect of the symptoms of gynecologic cancer may positively impact on patient QoL.

    Effects of verteporfin-mediated photodynamic therapy in breast cancer cells
    (National Institute of Science Communication and Information Resources, 2020) Sönmez P.K.; Turhan A.; Öztatlıcı M.; Özbilgin K.
    Photodynamic therapy works with a photosensitizer that is stimulated when exposed to a light source of a specific wavelength and produces a form of oxygen that can be used in cancer treatments. In this study, we investigated the effect of laser on apoptosis on breast cancer cell lines (MDA-MB-231) treated with verteporfin in cell culture media. Verteporfin added MDA-MB-231 cells were incubated without light for 24 hours after applying laser light at a wavelength of 695 nm at an intensity of 50 J/cm2 at various times. Anti-proliferative effects were evaluated by immunoreactivity of anti-Bcl-2 and anti-Bax antibodies by immunocytochemical staining. When anti-Bax/Anti-Bcl-2 ratio are compared, the ratio of 1.5 in the control group cells decreases in short-term laser applications, while it approaches normal values in the 7th min after long-term laser application and reaches a very high value in the 9th min. Therefore, our results suggest that verteporfin-mediated PDT may be a potential combined therapy strategy against breast carcinoma by increasing apoptosis. © 2020, National Institute of Science Communication and Information Resources (NISCAIR).

    Background: Appendicitis is the most prevalent surgical emergency. The negative appendicectomy rate and diagnostic uncertainty are important concerns. This study aimed to assess the effectiveness of current appendicitis risk prediction models in patients with acute right iliac fossa pain. Methods: A nationwide prospective observational study was conducted, including all consecutive adult patients who presented with right iliac fossa pain. Diagnostic, clinical and negative appendicectomy rate data were recorded. The Alvarado score, Appendicitis Inflammatory Response (AIR), Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) and Adult Appendicitis Score systems were calculated with collected data to classify patients into risk categories. Diagnostic value and categorization performance were evaluated, with use of risk category-based metrics including 'true positive rate' (percentage of appendicitis patients in the highest risk category), 'failure rate' (percentage of patients with appendicitis in the lowest risk category) and 'categorization resolution' (true positive rate/failure rate). Results: A total of 3358 patients from 84 centres were included. Female patients were less likely to undergo surgery than men (71.5% versus 82.5% respectively; relative risk 0.866, 95% c.i. 0.834 to 0.901, P < 0.001); with a three-fold higher negative appendicectomy rate (11.3% versus 4.1% respectively; relative risk 2.744, 95% c.i. 2.047 to 3.677, P < 0.001). Ultrasonography was utilized in 56.8% and computed tomography in 75.2% of all patients. The Adult Appendicitis Score had the best diagnostic performance for the whole population; however, only RIPASA was significant in men. All scoring systems were successful in females patients, but Adult Appendicitis Score had the highest area under the receiver operating characteristic curve value. The RIPASA and the Adult Appendicitis Score had the best categorization resolution values, complemented by their exceedingly low failure rates in both male and female patients. Alvarado and AIR had extremely high failure rates in men. Conclusion: The negative appendicectomy rate was low overall, but women had an almost three-fold higher negative appendicectomy rate despite lower likelihood to undergo surgery. The overuse of imaging tests, best exemplified by the 75.2% frequency of patients undergoing computed tomography, may lead to increased costs. Risk-scoring systems such as RIPASA and Adult Appendicitis Score appear to be superior to Alvarado and AIR. © 2024 The Author(s). Published by Oxford University Press on behalf of BJS Foundation Ltd.
