Item Coronaphobia: A barrier to ongoing cancer treatment?(WILEY, 2022-01-01) Sonmez, Ozlem; Tezcanli, Evrim; Tasci, Elif Senocak; Kazanci, Hande Busra; Altinok, Ayse; Toklucu, Elvan; Tasci, Yusuf; Aydogdu, Cise; Aydin, Aysegul Bakir; Yuce, Sabiha; Oyan, BasakIntroduction Increased stress levels caused by the pandemic might cause delays in cancer treatment. We conducted a survey among cancer patients undergoing treatment to evaluate their psychological wellbeing and treatment adherence during Coronavirus disease 19 (COVID-19) pandemic. Material and Methods Patients receiving active chemotherapy at a private oncology center between January and May 2021 were included. Healthy volunteers were employees of a district health directorate with no history of cancer or chronic disease. Treatment adherence was described as compliant if the prescribed treatment was received within a week and the information was gained from patient charts. Hospital anxiety and depression scale (HADS) and COVID-19 phobia scale (CP19-S) were administered to participants. Results 402 participants were includedItem Intramural Component of Venous, Lymphatic, and Perineural Invasion in Colon Cancer: A Threat or an Illusion?(GALENOS PUBL HOUSE, 2022-01-01) Ozer, Leyla; Tasci, Elif Senocak; Mutlu, Arda Ulas; Piyade, Betul; Ramoglu, Nur; Ajredini, Mirac; Gurleyik, Damla; Cecen, Recep; Dincer, Sena Nur; Musevitoglu, Turan; Goksel, Suha; Ince, Umit; Kayhan, Cavit Kerem; Erdamar, Sibel; Yildiz, Ibrahim; Aytac, ErmanBackground: Extramural venous invasion is an independent predictor of poor outcome in colorectal cancer, whereas the significance of the intramural component of venous and lymphatic and perineural invasion is unclear. Aims: To evaluate the prognostic impact of intramural components for venous, lymphatic, and perineural invasions and the relation of these invasion patterns with clinicopathological features in patients with colon cancer. Study Design: A retrospective cross-sectional study. Methods: The analysis included 626 patients with colon cancer in stages II and III. All patients were divided into four categories (no invasion, intramural invasion only, extramural invasion only, or both intramural and extramural invasions) for vascular invasion, lymphatic invasion and perineural invasion. The primary outcomes were 5-year disease-free and overall survival. Results: Right-sided (for vascular invasion, 24.7\% vs. 33.9\%, p = 0.007Item Real life experience of patients with locally advanced gastric and gastroesophageal junction adenocarcinoma treated with neoadjuvant chemotherapy: a Turkish oncology group study(TAYLOR \& FRANCIS LTD, 2022-01-01) Basoglu, Tugba; Sakin, Abdullah; Erol, Cihan; Ozden, Ercan; cabuk, Devrim; Cilbir, Ebru; Tataroglu ozyukseler, Deniz; Ayhan, Murat; Sendur, Mehmet Ali; Dogan, Mutlu; Oksuzoglu, Berna; Eryilmaz, Melek Karakurt; Er, Ozlem; Tasci, Elif Senocak; Ozyurt, Neslihan; Dulgar, Ozgecan; Ozen, Mirac; Hacibekiroglu, Ilhan; Oner, Irem; Bekmez, Esma Turkmen; Cagri Yildirim, Hasan; Yalcin, Suayib; Paydas, Semra; Yekeduz, Emre; Aksoy, Asude; Ozcelik, Melike; Oyman, Abdilkerim; Almuradova, Elvina; Karabulut, Bulent; Demir, Nazan; Dincer, Murat; Ozdemir, Nuriye; Erdem, Dilek; Ak, Naziye; Inal, Ali; Salim, Derya Kivrak; Deniz, Gulhan Ipek; Sakalar, Teoman; Gulmez, Ahmet; Kacan, Turgut; Ozdemir, Ozlem; Alan, Ozkan; Unal, Caglar; Karakas, Yusuf; Turhal, Serdar; Yumuk, Perran FuldenNeoadjuvant chemotherapy (NACT) in gastroesophageal junction (GEJ) and gastric cancer (GC) was shown to improve survival in recent studies. We aimed to share our real-life experience of patients who received NACT to compare the efficacy and toxicity profile of different chemotherapy regimens in our country. This retrospective multicentre study included locally advanced GC and GEJ cancer patients who received NACT between 2007 and 2021. Relation between CT regimens and pathological evaluation were analysed. A total of 794 patients from 45 oncology centers in Turkey were included. Median age at the time of diagnosis was 60 (range: 18-86). Most frequent NACT regimens used were FLOT (65.4\%), DCF (17.4\%) and ECF (8.1\%), respectively. In the total study group, pathological complete remission (pCR) rate was 7.2\%, R0 resection rate 86.4\%, and D2 dissection rate was 66.8\%. Rate of pCR and near-CR (24\%), and R0 resection (84\%) were numerically higher in FLOT arm (p > 0.05). Patients who received FLOT had also higher chemotherapy-related toxicity rate compared to patients who received other regimens (p > 0.05). Median follow-up time was 16 months (range: 1-154 months). Estimated median overall survival (OS) was 58.4months (95\% CI: 35.2-85.7) and disease-free survival (DFS) was 50.7 months (95\% CI: 25.4-75.9). The highest 3-year estimated OS rate was also shown in FLOT arm (68\%). We still do not know which NACT regimen is the best choice for daily practice. Clinicians should tailor treatment regimens according to patients' multifactorial status and comorbidities for to obtain best outcomes. Longer follow-up period needs to validate our results.Item The Relationship between the Sydney Classification and the First-Line Treatment Efficacy in Helicobacter-Associated Gastritis(KARGER, 2020-01-01) Tasci, Elif Senocak; Akbas, TurkayObjective: Helicobacter pyloriis responsible for a wide spectrum of diseases. Due to ease of use and access, the standard triple therapy is being used as first-line eradication in many areas. Intestinal metaplasia (IM) is a precancerous lesion that requires eradication therapy. Our aim is to investigate the effect of IM on the standard triple therapy success in H. pylori-positive patients. Subjects and Methods: The patients who were referred to Duzce University Hospital and Avrasya Hospital Gastroenterohepatology clinic between January 2014 and December 2016 and diagnosed with H. pylori-positive gastritis and underwent first-line eradication were evaluated retrospectively. Biopsy specimens were evaluated according to the updated Sydney system. All patients diagnosed with H. pylori started treatment with pantoprazole 40 mg b.i.d., amoxicillin 1 g b.i.d. and clarithromycin 500 mg b.i.d. for 14 days. Results: The mean age of 181 patients included in the study was 55.5 +/- 7.8. The success rate of H. pylori eradication was found to be low in severe chronic inflammation (p = 0.001). The success rate was found to be high among patients with no neutrophil activity (p = 0.009). As the intensity of IM increased, density of H. pylori was found to be decreased (p = 0.019). There was no correlation between glandular atrophy, IM, and H. pylori eradication success rate (p = 0.390 and p = 0.812). Conclusion: The severity of chronic inflammation is the most effective Sydney criteria for success of eradication, while the presence on IM does not have any effect.
