Publication Open Access Role of baseline Ga-68-PSMA PET/CT-derived whole-body volumetric parameters in predicting survival outcomes of metastatic castration-resistant prostate cancer patients receiving first-line treatment(2022-08-01) AKIN TELLİ, TUĞBA; ÖZGÜVEN, SALİH; FİLİZOĞLU, NUH; ÖZTÜRK, MEHMET SAADEDDİN; ARIKAN, RUKİYE; DEMİRCAN, NAZIM CAN; BAŞOĞLU TÜYLÜ, TUĞBA; ALSAN ÇETİN, İLKNUR; ÖNEŞ, TUNÇ; DANE, FAYSAL; YUMUK, PERRAN FULDEN; AKIN TELLİ T., ÖZGÜVEN S., Alan O., Filizoglu N., ÖZTÜRK M. S. , Sariyar N., Isik S., Arikan R., DEMİRCAN N. C. , BAŞOĞLU TÜYLÜ T., et al.Objective We aimed to evaluate whether baseline Ga-68-PSMA PET/CT-derived whole-body volumetric parameters could be used as predictive biomarkers for survival in metastatic castration-resistant prostate cancer (mCRPC) patients receiving first-line treatment. Materials and methods This retrospective study included 54 mCRPC patients, who underwent baseline Ga-68-PSMA PET/CT imaging within 1 month before starting first-line treatment. Pre-treatment prostate-specific antigen (PSA) levels and treatments were recorded. SUVmax, SUVmean, whole-body PSMA-derived tumor volume (wbPSMA-TV), and whole-body total lesion PSMA (wbTL-PSMA) were calculated for all patients. PSA response was defined as a decline of >= 50% from pre-treatment value at 12 weeks. Overall survival (OS) was measured from the start of the first-line treatment for mCRPC. Results Docetaxel and abiraterone/enzalutamide were administered to 32 and 22 patients in the first-line setting, respectively. wbPSMA-TV (rho = 0.582, p = 0.004) and wbTL-PSMA (rho = 0.564, p = 0.007) showed moderate positive correlations with PSA levels. Older age (p = 0.02), higher wbPSMA-TV (p = 0.007), higher PSA (p = 0.01), higher number of bone metastases (p = 0.02), and lack of PSA response (p = 0.03) were significantly associated with an increased risk of mortality. Multivariate analysis determined wbPSMA-TV (HR: 1.003, 95% CI 1.001-1.004, p = 0.001) and PSA response (HR: 2.241, 95% CI 1.189-4.222, p = 0.01) as independent predictors of OS. Conclusion The wbPSMA-TV may be a useful tool to reflect tumor burden and predict survival outcomes in patients with mCRPC.Publication Metadata only Differences in PET/CT standardized uptake values involvement and survival compared to histologic subtypes of lung adenocarcinoma(SAGE PUBLICATIONS LTD, 2021) BOZKURTLAR, EMİNE; Ercelep, Ozlem; Alan, Ozkan; Telli, Tugba A.; Tuylu, Tugba B.; Arikan, Rukiye; Demircan, Nazim Can; Simsek, Eda T.; Babacan, Nalan A.; Kaya, Serap; Dane, Faysal; Bozkurtlar, Emine; Ones, Tunc; Lacin, Tunc; Yumuk, Perran FuldenPurpose: Lung adenocarcinoma is histologically diverse but has distinct histologic growth patterns. There is no consensus on the clinical benefit of this histologic model. We aimed to evaluate the differences in the distribution of the preoperative primary tumor positron emission tomography (PET)/computed tomography (CT) standardized uptake values (SUVs) and survival in the lung adenocarcinoma subtypes. Methods: We retrospectively evaluated the data of 107 patients with resected lung adenocarcinoma who had preoperative PET/CT between 2005 and 2017 in a single center. Patients had lepidic, acinar, papillary, micropapillary, and solid histologic subtypes. We compared fluorodeoxyglucose SUVs and survival data of histologic subtypes. Results: The median age of the patients was 62 years (40-75), 76.4% were male, the median SUVmax was 9.4 (1-36.7), and the median follow-up time was 29 months (3-135 months). The median overall survival (OS) was 71 months and the median progression-free survival (PFS) was 33 months. SUVmax was significantly different in histologic subtypes: values for papillary, micropapillary, solid, acinar, and lepidic subtypes were 9.7, 8, 12, 9.1, and 3.9, respectively (p= 0.000). Solid predominant adenocarcinoma had significantly higher SUVmax than the other subtypes (p= 0.001). Lepidic predominant adenocarcinoma had significantly lower SUVmax than the other subtypes (p= 0.000). There was no significant difference in OS between histologic subtypes (p= 0.66), but PFS was significantly different between the groups (p= 0.017), and the solid subtype had a shorter PFS than the other histologic subtypes. Conclusion: Lung adenocarcinoma consists of a diverse group of diseases. Different SUVmax values are seen in different histologic subtypes of nonmetastatic lung adenocarcinoma. Solid predominant types have high SUVmax values while lepidic predominant types have lower SUVmax values. The solid subtype had a shorter PFS than the other histologic subtypes.Publication Metadata only QT interval prolongation related to afatinib treatment in a patient with metastatic non-small-cell lung cancer(MOSBY-ELSEVIER, 2020) KOCAKAYA, DERYA; Demircan, Nazim Can; Telli, Tugba Akin; Tuylu, Tugba Basoglu; Arikan, Rukiye; Kocakaya, Derya; Sahin, Ahmet Anil; Ercelep, Ozlem; Dane, Faysal; Yumuk, Perran FuldenAfatinib improves survival in metastatic non-small-cell lung cancer driven by activating epidermal growth factor receptor mutations. QT interval prolongation is a possible side effect of tar geted anticancer drugs, but this has not been reported before with afatinib. We report a case of metastatic pulmonary adenocarcinoma with epidermal growth factor receptor exon 19 deletion who was treated with first-line afatinib. The patient was started on afatinib with a total dose of 40 mg/day and experienced grade 3 (> 500 ms) QT interval prolongation in the seventh week. Dose was interrupted and then reduced to 30 mg/day after the event repeated. QT prolongation occurred only once with the reduced dose and radiologic oligoprogression was detected. Local therapy was performed and afatinib was continued as 30 mg/day. To the best of our knowledge, this case marks the first QT interval prolongation associated with afatinib. It is prudent to perform a baseline cardiologic evaluation and electrocardiogram monitoring in non-small cell lung cancer patients treated with this drug. (c) 2020 Elsevier Inc.

Breast metastasis of gastric cancer is another uncommon entity. We present a rare case of breast metastasis of gastric cancer during pregnancy. Case report A 26-year-old female was diagnosed with gastric cancer at 14 weeks of gestation and underwent total gastrectomy. She rejected adjuvant chemotherapy and continued pregnancy without any follow-up. Cancer recurred in bilateral breasts at 34th week of gestation mimicking primary inflammatory breast cancer. Management and outcome It was difficult to diagnose breast metastasis during pregnancy because of overlapping pregnancy symptoms. Following an unresponsive period to antibiotherapy, a fine needle biopsy on breast was performed and signet cell adenocarcinoma metastasis was determined. We started chemotherapy after delivery. There was a near complete response after first line of chemotherapy. Unfortunately, cancer was relapsed within three months and we started second-line chemotherapy. Discussion To our knowledge, this is the fourth case reported in medical literature of gastric cancer presented with breast metastasis during pregnancy. We will try to draw attention to diagnosis, treatment and different presentation of gastric cancer during pregnancy with review of the literature.Publication Metadata only Prognostic factors in patients with metastatic urothelial carcinoma who have treated with Atezolizumab(SPRINGER JAPAN KK, 2021) KÖSTEK, OSMAN; Tural, Deniz; Olmez, Omer Fatih; Sumbul, Ahmet Taner; Ozhan, Nail; Cakar, Burcu; Kostek, Osman; Ekenel, Meltem; Erman, Mustafa; Coskun, Hasan Senol; Selcukbiricik, Fatih; Keskin, Ozge; Turkoz, Fatma Paksoy; Oruc, Kerem; Bayram, Selami; Bilgetekin, Irem; Yildiz, Birol; Sendur, Mehmet Ali Nahit; Paksoy, Nail; Dirican, Ahmet; Erdem, Dilek; Selam, Meltem; Tanriverdi, Ozgur; Paydas, Semra; Urakci, Zuhat; Atag, Elif; Guncan, Sabri; Urun, Yuksel; Alkan, Ali; Kaya, Ali Osman; Ozyukseler, Deniz Tataroglu; Taskaynatan, Halil; Yildirim, Mustafa; Sonmez, Muge; Basoglu, Tugba; Gunduz, Seyda; Kilickap, Saadettin; Artac, MehmetBackground Atezolizumab (ATZ) has demonstrated antitumor activity and manageable safety in previous studies of patients with metastatic platinum-resistant urothelial carcinoma. However, the response rate of Atezolizumab was modest. In the current study, we evaluated the pretreatment prognostic factors for overall survival in patients with metastatic urothelial carcinoma who have progressed after first-line chemotherapy in the Expanded-Access Program of Atezolizumab. Patients and methods In this study, we present a retrospective analysis of 113 patients with urothelial cancer treated with ATZ after progression on first-line chemotherapy. Data of the patients was obtained from patient files and hospital records. Eligible patients included metastatic urothelial carcinoma patients treated with at least one course of ATZ. Univariate analysis was used to identify clinical and laboratory factors that significantly impact OS. Variables were retained for multivariate analysis if they had a statistical relationship with OS (p < 0.1), and then included a final model of p < 0.05. Results The median follow-up duration was 23.5 months. Of the patients, 98 (86.7%) were male and 13.3% were female. The median age was 65 years of age (37-86). In univariate analysis, primary tumor location in the upper tract, increasing absolute neutrophil count (ANC), increasing absolute lymphocyte count, neutrophil-to-lymphocyte ratio (NLR) > 3, liver metastases, baseline creatinine clearance less (GFR) than 60 ml/min, Eastern Cooperative Oncology Group (ECOG) performance status (1 >=), and hemoglobin levels below 10 mg/dl were all the significantly associated with OS. Three of the five adverse prognostic factors according to the Bellmunt criteria were independent of short survival: liver metastases HR 3.105; 95% CI 1.673-5.761; p < (0.001), ECOG PS (1 >=) HR 2.184; 95% CI 1.120-4.256; p = 0.022, and Hemoglobin level below 10 mg/dl HR 2.680; 95% CI 1.558-4.608; p < (0.001). In addition, NLR > 3 hazard ratio [HR] 2.092; 95% CI 1.031-4.243; p = 0.041 and GFR less than 60 ml/min HR 1.829; 95% CI 1.1-3.041; p = 0.02, maintained a significant association with OS in multivariate analysis. Conclusions This model confirms the Bellmunt model with the addition of NLR > 3 and GFR less than 60 ml/min and can be associated with clinical trials that use immunotherapy in patients with bladder cancer.Publication Open Access Prognostic Value of Tissue-Resident Memory T Cells and Tumor Microenvironmental Features in Resected Pancreatic Adenocarcinoma(2021) ÖZTÜRK, FATİH EMİN; Başoğlu, Tuğba; Akar, Kadriye Ebru; Bağcı, Pelin; Akgül Babacan, Nalan; Öztürk, Mehmet Akif; Öztürk, Fatih Emin; Demircan, Nazım Can; Arikan, Rukiye; Akın Telli, Tuğba; Ercelep, Özlem; Dane, Faysal; Yumuk, Perran FuldenBACKGROUND: Pancreatic ductal adenocarcinoma differs from other solid tumors with its unique immunosuppressive microenvironment and non-immunogenic feature. There are not many studies in the literature investigating the effect of these features on prognosis. AIM: To investigate the prognostic value of tissue-resident memory cells, tumor microenvironment features, and tumor-associated immune cells in resected pancreatic ductal adenocarcinomas. STUDY DESIGN: Retrospective cross-sectional study. METHODS: Of 138 patients diagnosed with pancreatic ductal adenocarcinoma between 2011 and 2018, 81 were included in the study. Specimens from operated patients were reassessed separately as peritumoral and intratumoral areas for tissue resident memory and tumor microenvironmental elements (tumor infiltrating lymphocytes, tumor stroma, CD204+ macrophages, PDL1+ immune cells). Disease-free survival and overall survival were defined from the date of operation to the date of recurrence and the date of first diagnosis to the date of death, respectively. If the patient was alive, the last visit date was taken into account. RESULTS: The median age at diagnosis was 63 (range: 40-78). The median follow-up period was 18.9 months (range 1.4-80.4 months). Median overall survival was 23.7 months (1.4-80.4 months) and median disease-free survival was 10.8 months (1.4-74.4 months). Patients with higher intra-tumoral tissue-resident memory cell counts had a longer survival trend than those having lower values (25.6 months vs. 18 months, respectively, P = .84). According to microenvironmental evaluations, lower stromal score (defined as stroma having less desmoplasia and rich in cells) and presence of peritumoral Crohn's-like inflammatory response were associated with higher survival (29.2 months vs. 19.7 months for low vs. high stromal scores, respectively, P = .16 and 30.2 months vs. 18.1 months for the presence of Crohn's-like inflammatory response P = .13). Decreased survival was observed in tumors with increased CD204+ tumor-associated macrophages which were immunosuppressive elements of the microenvironment (12 months vs. 26.3 months for intra-tumoral assessment, P = .29). CONCLUSION: Tissue-resident memory cells and other microenvironmental features may be prognostic in resectable pancreatic ductal adenocarcinomas. Further studies with larger cohorts are needed for validation.Publication Metadata only The real-life efficacy and safety of osimertinib in pretreated advanced non-small cell lung cancer patients with T790M mutation: a Turkish Oncology Group Study(SPRINGER) YUMUK, PERRAN FULDEN; Hizal, Mutlu; Bilgin, Burak; Paksoy, Nail; Acikgoz, Ozgur; Sezer, Ahmet; Gurbuz, Mustafa; Ak, Naziye; Yucel, Sebnem; Ayhan, Murat; Erol, Cihan; Demirkiran, Aykut; Mandel, Nil Molinas; Shbair, Abdallah; Gokmen, Ivo; Basoglu, Tugba; Paydas, Semra; Demiray, Atike Gokcen; Iriagac, Yakup; Sakalar, Teoman; Zeynelgil, Esra; Tatli, Ali Murat; Bahceci, Aykut; Guven, Deniz Can; Caner, Burcu; Can, Alper; Gulmez, Ahmet; Karakas, Yusuf; Yalcin, Bulent; Demirkazik, Ahmet; Bilici, Ahmet; Aydiner, Adnan; Yumuk, Perran Fulden; Sendur, Mehmet Ali NahitIntroduction Osimertinib, an irreversible third-generation EGFR-TKI, is the standard of care for second-line treatment of T790M-mutant advanced NSCLC patients whose disease progressed after first-line EGFR-TKI therapy. In this multicenter study, we aimed to determine the real-life efficacy and safety of Osimertinib in pretreated advanced NSCLC patients with T790M mutation. Materials and methods This retrospective trial included advanced T790M-mutant pretreated NSCLC patients who received Osimertinib from 24 different centers in Turkey. Primary endpoint was time-to-treatment discontinuation (TTD). Secondary endpoints were objective response rate (ORR), overall survival (OS), and safety. Results Of 163 patients, 68.7% had EGFR exon 19 deletion and 22.7% had exon 21 L858R mutation. Osimertinib was given as second-line treatment in 96 patients (58.9%) and third-line in 48 patients (29.4%). After median of 13-month follow-up, median TTD was 21.6 months with an 82.2% ORR. Estimated median OS was 32.1 months. Grade 3-4 adverse events were seen in 11.7% of the patients. Conclusion Osimertinib is a highly effective option in second- or third-line treatment of NSCLC patients with T790M mutation, with a favorable safety profile.Publication Open Access Real life experience of patients with locally advanced gastric and gastroesophageal junction adenocarcinoma treated with neoadjuvant chemotherapy: A Turkish oncology group study(2023-01-01) BAŞOĞLU TÜYLÜ, TUĞBA; YUMUK, PERRAN FULDEN; BAŞOĞLU TÜYLÜ T., Sakin A., Erol C., Ozden E., ÇABUK D., Cilbir E., Tataroglu ozyukseler D., Ayhan M., Sendur M. A., Dogan M., et al.Neoadjuvant 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.Publication Metadata only Worse patient-physician relationship is associated with more fear of cancer recurrence (Deimos Study): A study of the Palliative Care Working Committee of the Turkish Oncology Group (TOG)(WILEY, 2020) YUMUK, PERRAN FULDEN; Alkan, Ali; Yasar, Arzu; Guc, Zeynep Gulsum; Gurbuz, Mustafa; Basoglu, Tugba; Goksu, Sema Sezgin; Basal, Fatma Bugdayci; Turk, Haci Mehmet; Ozdemir, Ozlem; Cinkir, Havva Yesil; Guven, Deniz Can; Kus, Tulay; Turker, Sema; Koral, Lokman; Karakas, Yusuf; Ak, Naziye; Paydas, Semra; Karci, Ebru; Demiray, Atike Gokcen; Demir, Atakan; Alan, Ozkan; Keskin, Ozge; Nayir, Erdinc; Tanriverdi, Ozgur; Yavuzsen, Tugba; Yumuk, Perran Fulden; Ates, Ozturk; Coskun, Hasan Senol; Turhal, Serdar; Senler, Filiz CayObjective Fear of cancer recurrence (FCR) is an important psychological trauma associated with reduction in the quality of life, disruptions in the level of adjustment, emotional distress and anxiety. The purpose of the study was to evaluate the impact of patient-physician relationship on FCR. Methods The study was designed as a multicentre survey study. The cancer survivors, who were under remission, were evaluated with structured questionnaires. Patient-physician relationship (PPR) scale in which higher scores indicate better relationship and FCR inventory was used. Results Between January and April 2019, 1,580 patients were evaluated. The median age was 57.0 (19-88), and 66% were female. There was high level of FCR scores in 51% of participants. There was a negative correlation between PPR and FCR scores (r = -.134,p < .001). In multivariate analysis, young age, female gender, history of metastasectomy and worse PPR were associated with high levels of FCR. Conclusion It is the first data showing the adverse impact of worse PPR on FCR. The strategies to improve the PPR should be practised. In addition, the cancer survivors, who are under the risk of FCR, should be evaluated and managed.Publication Metadata only Real-world assessment of quality-of-life in patients with breast cancer treated with adjuvant endocrine therapy(2022-07-01) ARIKAN, RUKİYE; BAŞOĞLU TÜYLÜ, TUĞBA; DANE, FAYSAL; YUMUK, PERRAN FULDEN; KÖSTEK, OSMAN; AKIN TELLİ T., ÖZTÜRK M. S., Alan O., Hasanov R., KÖSTEK O., Arikan R., BAŞOĞLU TÜYLÜ T., Kaya S., Ercelep O., Babacan N. A., et al.Objective: The aim of this study was to investigate quality-of-life (QoL) in breast cancer (BC) patients treated with adjuvant endocrine therapy (AET). Methods: We designed a cross-sectional study of 233 BC patients treated with AET and used the Functional Assessment of Cancer Therapy - Breast questionnaire. Results: No significant difference was observed between endocrine agents. Duration of AET did not affect QoL. In the entire cohort, multivariate analysis determined age (p = 0.034) and switching treatment from tamoxifen to aromatase inhibitors (p = 0.049) as significant positive coefficients of QoL, while comorbidity (p = 0.072) tended to be associated with lower scores. Education level (p = 0.001) and chemotherapy (p = 0.04) were significant predictors of QoL in the tamoxifen group, while comorbidity (p = 0.04), surgery type (p = 0.02), radiotherapy (p = 0.006) and stage (p = 0.009) had a significant impact on QoL in aromatase inhibitors group. Conclusion: Evaluating the well-being of BC patients by QoL questionnaires is of great importance to identify particular subgroups that may require supportive care.
