In this study, we analyzed clinical and pathological features of male breast cancer cases, which had been followed up and treated at our institution.Material and Method: The data regarding the main clinicopathological features of the male breast cancer patients were retrieved from the patients' records retrospectively.Results: A total of 16 patients were included in the analysis with a median age of 60 (41-75). The most common cell type was infiltrating ductal carcinoma, comprising 81.3 % of all cases. Most patients were staged as locally advanced (50% - stage 3) at the time of diagnosis. Estrogen and/or progesterone receptor positivity were found in 13 patients (81.3%). HER2 status could be examined in 9 patients, and 4 patients (25%) found to be positive for HER2 overexpression. Overall survival was 3(1-12) years and disease-free survival was 2 (1-8) years.Discussion: Despite the increasing knowledge about breast cancer in women, little is known in case of male breast cancer management. Therefore, there is a strong need to perform randomized studies for the treatment of male breast cancer.Publication Real-life experience with chemotherapy plus biologics in first-line treatment of right-sided, ras wild-type, metastatic colon cancer: A multicenter onco-colon Turkey study(Elsevier, 2021-07-03) Arslan, C.; Kefeli, U.; Yildirim, E.; Isikdogan, A.; Karadurmus, N.; Karabulut, B.; Cicin, I.; Bilir, C.; Ozcelik, M.; Cil, T.; Celik, S.; Bozkurt, O.; Harputluoglu, H.; Oven, B.; Geredeli, C.; Tural, D.; Sakin, A.; Cevik, D.; Gumus, M.; Yalcin, S.; Çubukcu, E.; ÇUBUKÇU, ERDEM; Bursa Uludağ Üniversitesi/Tıp Fakültesi.; 0000-0002-7584-3868; 0000-0002-1372-4791; 0000-0001-6906-7500; 0000-0002-3982-7465; 0000-0003-3550-9993; 0000-0002-1618-1147; HTO-4176-2023; I-1932-2016; A-2491-2017Publication Trastuzumab ± capecitabine maintenance after the first-line treatment of HER2-positive advanced gastric cancer: Retrospective observational real-life data of Turkish oncology group(Springer, 2021-01-24) Gürbüz, Mustafa; Akkuş, Erman; Sakin, Abdullah; Urvay, Semiha; Demiray, Atike Gökçen; Şahin, Süleyman; Sakalar, Teoman; Erol, Cihan; Şendur, Mehmet Ali Nahit; Şahin, Ahmet Bilgehan; Çubukcu, Erdem; Guven, Deniz Can; Kılıçkap, Saadettin; Ergün, Yakup; Uncu, Doğan; Turhal, Nazim Serdar; Uskent, Necdet; Çınkır, Havva Yeşil; Demir, Atakan; Acar, Ramazan; Karadurmuş, Nuri; Türker, Sema; Altınbaş, Mustafa; Karaoğlan, Mert; Şenler, Filiz Çay; ŞAHİN, AHMET BİLGEHAN; ÇUBUKÇU, ERDEM; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Onkoloji Anabilim Dalı.; 0000-0002-7846-0870 ; 0000-0002-0070-0889; AAM-4927-2020 ; JGT-4101-2023Purpose In the ToGA trial for HER2-positive advanced gastric cancer, cisplatin plus fluoropyrimidine was given for 6 cycles; trastuzumab was given until disease progression. However, there is a lack of real-life data about trastuzumab maintenance after 6 cycle chemotherapy. This study aims to present real-life data of trastuzumab +/- capecitabine maintenance after 6 cycles of platinum, fluoropyrimidine, and trastuzumab in non-progressive patients. Methods This is a retrospective multicenter study of the Turkish Oncology Group. A total of 35 HER2-positive, inoperable locally advanced, recurrent, or metastatic gastric adenocarcinoma patients being non-progressive at the end of 6 cycle chemotherapy and being given trastuzumab +/- capecitabine as maintenance treatment were included from sixteen oncology centers. Baseline characteristics, objective tumor responses, progression free and overall survival data, and toxicities were determined. Results About 68% of the patients were given CF, and 32% were given FOLFOX with trastuzumab as the first-line treatment. The best response in 6 cycle chemotherapy was complete 8 (22%), partial 24 (68%), and stable disease 3 (8%). All patients had trastuzumab maintenance (median cycle 13; range 7-51), and 49% of the patients had capecitabine with trastuzumab (median capecitabine cycle 6; range 2-30). The median PFS of the patients was 12.0 months (95% CI 10.3-13.7), and median OS was 17.4 months (95% CI 15.2-19.5). There were 2 patients with grade 1 cardiotoxicity. Conclusion Trastuzumab maintenance +/- capecitabine after 6 cycles of trastuzumab plus combined chemotherapy treatment revealed efficacy and safety in non-progressive HER2-positive advanced gastric cancer.Publication Efficacy of sunitinib in patients with imatinib-resistant gastrointestinal stromal tumors(Derman Medical Publ, 2014-07-01) Çubukcu, Sinem; Kanat, Özkan; Çubukcu, Erdem; Ölmez, Ömer Fatih; Canhoroz, Mustafa; Avcı, Nilüfer; Hartavi, Mustafa; Deligönül, Adem; Seyhan, Serdar; Ayyıldız, Aylin; Taşdemir, Ünal; Manavoğlu, Osman; ÇUBUKÇU, SİNEM; Kanat, Özkan; ÇUBUKÇU, ERDEM; Ölmez, Ömer Fatih; Canhoroz, Mustafa; Avcı, Nilüfer; Hartavi, Mustafa; DELİGÖNÜL, ADEM; Seyhan, Serdar; Ayyıldız, Aylin; Taşdemir, Ünal; Manavoğlu, Osman; Uludağ Üniversitesi/Tıp Fakultesi/İç Hastalıkları Anabilim Dalı,; Uludağ Üniversitesi/Tıp Fakultesi//Tıbbi Onkoloji Bilim Dalı.; JJB-0254-2023; JRU-4028-2023; JGT-4101-2023; DJG-4827-2022; CJW-6018-2022; CCT-7946-2022; CUI-5353-2022; JHC-1731-2023; DSI-5869-2022; KGG-2754-2024; KBV-2934-2024; FLP-9613-2022Aim: In this study, the efficacy of sunitinib in patients with imatinib-resistant gastrointestinal stromal tumors (GISTs) was investigated. Material and Method: A total of 11 imatinib-resistant GIST patients who have sufficient information about their medical treatment and outcome were retrospectively analyzed. Results: Partial response was observed in only two patients, and five patients achieved stable disease. Progression free survival and overall time was 8.8 months and 12 months, respectively. Sunitinib was relatively well tolerated. Almost all patients experienced one or more treatment-related adverse event. Discussion: Based on our limited experience, we concluded that sunitinib is reasonable treatment option for patients with imatinibresistant GIST.Publication Clinical and laboratory outcomes of solid cancer patients reinfected with sars-cov-2(Elsevier, 2021-09-21) Yazici, O.; Unsal, O.; Ozdemir, N.; Uner, A.; Ozet, A.; Cubukcu, E.; ÇUBUKÇU, ERDEM; Ocak, B.; OCAK, BİROL; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Onkoloji Anabilim Dalı.; 0000-0001-7537-1699; 0000-0001-8731-9636; ABC-9831-2021Publication Treatment efficacy of ribociclib or palbociclib plus letrozole in hormone receptor-positive/HER2-negative metastatic breast cancer(Future Medicine Ltd, 2023-05-03) Kahraman, Seda; Erul, Enes; Seyyar, Mustafa; Gumusay, Ozge; Bayram, Ertugrul; Demirel, Burcin Cakan; Acar, Omer; Aksoy, Sercan; Baytemur, Naziyet Kose; Sahin, Elif; Cabuk, Devrim; Basaran, Gul; Paydas, Semra; Yaren, Arzu; Guven, Deniz Can; Erdogan, Atike Pinar; Demirci, Umut; Yasar, Alper; Bayoglu, Ibrahim Vedat; Hizal, Mutlu; Gulbagci, Burcu; Paksoy, Nail; Davarci, Sena Ece; Yilmaz, Funda; Dogan, Ozlem; Orhan, Sibel Oyucu; Kayikcioglu, Erkan; Aytac, Ali; Keskinkilic, Merve; Mocan, Eda Eylemer; Unal, Olcun Umit; Aydin, Esra; Yucel, Hakan; Isik, Deniz; Eren, Onder; Uluc, Basak Oyan; Ozcelik, Melike; Hacibekiroglu, Ilhan; Aydiner, Adnan; Demir, Hacer; Oksuzoglu, Berna; Cilbir, Ebru; Cubukcu, Erdem; Cetin, Bulent; Oktay, Esin; Erol, Cihan; Okutur, Sadi Kerem; Yildirim, Nilgun; Alkan, Ali; Selcukbiricik, Fatih; Aksoy, Asude; Karakas, Yusuf; Ozkanli, Gulhan; Duman, Berna Bozkurt; Aydin, Dincer; Dulgar, Ozgecan; Er, Muhammed Muhiddin; Teker, Fatih; Yavuzsen, Tugba; Aykan, Musa Baris; Inal, Ali; Iriagac, Yakup; Kalkan, Nurhan Onal; Keser, Murat; Sakalar, Teoman; Menekse, Serkan; Kut, Engin; Bilgin, Burak; Karaoglanoglu, Muge; Sunar, Veli; Ozdemir, Ozlem; Turhal, Nazim Serdar; Karadurmus, Nuri; Yalcin, Bulent; Sendur, Mehmet Ali Nahit; OYUCU ORHAN, SİBEL; ÇUBUKÇU, ERDEM; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Onkoloji Anabilim Dalı.; 0000-0001-8217-3471 ; ETP-1691-2022; AAJ-8314-2021Background: Ribociclib, palbociclib and abemaciclib are currently approved CDK4/6 inhibitors along with aromatase inhibitors as the first-line standard-of-care for patients with hormone receptor-positive, HER2-negative metastatic breast cancer. Methods: The authors report retrospective real-life data for 600 patients with estrogen receptor- and/or progesterone receptor-positive and HER2-negative metastatic breast cancer who were treated with ribociclib and palbociclib in combination with letrozole. Results & conclusion: The results demonstrated that the combination of palbociclib or ribociclib with letrozole has similar progression-free survival and overall survival benefit in real life for the patient group with similar clinical features. Specifically, endocrine sensitivity may be a factor to be considered in the treatment preference.Publication Retrospective comparison of the efficacy of therapeutic agents in metastatic soft-tissue sarcomas(Kare Yayınevi, 2023-03-02) Caner, Burcu; Ocak, Birol; Şahin, Ahmet Bilgehan; Salı, Seda; Çoban, Eyüp; Deligönul, Adem; Çubukçu, Erdem; Evrensel, Türkkan; CANER, BURCU; SALİ, SEDA; ÇOBAN, EYÜP; DELİGÖNÜL, ADEM; ÇUBUKÇU, ERDEM; EVRENSEL, TÜRKKAN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Onkoloji Anabilim Dalı.; 0000-0003-1591-3323 ; HJH-6371-2023; DPO-3759-2022; JIS-1916-2023; JHC-1731-2023; JGT-4101-2023; EXZ-0745-2022OBJECTIVEThere are few agents used in soft-tissue sarcoma treatment. We compared the efficacy of therapies, aiming to identify the best therapy sequence, and reveal the factors affecting the risk of progression or death.METHODSFifty-five patients were included in the study. Data such as age, gender, tumor primary site, histological type, tumor grade, the Ki67 percentage score, treatments, radiotherapy, and metastasectomy history, the dates of diagnosis, metastasis, progression, and death were retrospectively evaluated. Progression-free survival (PFS) and overall survival (OS) for therapies, and the risk factors for the progression or death were analyzed.RESULTSIn the first-line, gemcitabine-docetaxel provided longer PFS than the doxorubicin-ifosfamide combination (7.4 months vs. 4.8 months, p=0.035), although this did not result in OS difference. In the second line, the efficacy of trabectedin and pazopanib were similar, whereas trabectedin showed less activity in liposarcomas. In the third-line and beyond, trabectedin, pazopanib and eribulin showed similar PFS and OS. The only factor that affected the risk of death was metastasectomy (HR for death: 0.35, 95% CI: 0.18-0.66, p=0.001). CONCLUSIONWe found that agents used in soft-tissue sarcoma have similar efficacy, which is not affected by the previous therapies. However, it should be noted that soft-tissue sarcomas include many histological types, and to choose the optimal drug, the histological type must be one of the major factors considered. Furthermore, all patients should be evaluated for possible metastasectomy, which came out as the only factor reducing the risk of death in our study.Publication DPYD c.1905+1G>A promotes fluoropyrimidine-induced anemia, a prognostic factor in disease-free survival, in colorectal cancer(Mary Ann Liebert, Inc, 2021-04-01) Deligönül, Adem; Aksoy, Seçil; Tezcan, Gülçin; Tunca, Berrin; Kanat, Özkan; Çubukcu, Erdem; Yılmazlar, Tuncay; Öztürk, Ersin; Egeli, Ünal; Çeçener, Gülşah; Alemdar, Adem; Evrensel, Türkkan; DELİGÖNÜL, ADEM; AKSOY, SEÇİL; TEZCAN, GÜLÇİN; TUNCA, BERRİN; Kanat, Özka; ÇUBUKÇU, ERDEM; YILMAZLAR, AHMET TUNCAY; EGELİ, ÜNAL; ÇEÇENER, GÜLŞAH; ALEMDAR, ADEM; EVRENSEL, TÜRKKAN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Onkoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Diş Hekimliği Fakültesi/Temel Bilimler Bölümü.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Biyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Onkoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Genel Cerrahi Anabilim Dalı.; Bursa Uludağ Üniversitesi/Sağlık Bilimleri Enstitüsü.; 0000-0002-6400-4911; 0000-0002-5956-8755; 0000-0002-1619-6680; 0000-0001-8593-5101; 0000-0001-7904-883X; 0000-0002-3820-424X; HIZ-7332-2022; AAH-1420-2021; AAH-3843-2020; ESM-4544-2022; JDG-0330-2023; ABI-6078-2020; CYM-0930-2022; ETP-1691-2022; CKK-3621-2022; AAP-9988-2020; EXZ-0745-2022Background and Aim: In 10-30% of colorectal cancer (CRC) patients, toxic reactions occur after fluoropyrimidine-based chemotherapy. A dihydropyridine dehydrogenase (DPYD) gene variant, c.1905 + 1G>A, leads to intolerance to fluoropyrimidines. Due to the low frequency of this variant in many populations, the prevalence of fluoropyrimidine-induced hematologic side effects in CRC patients with the c.1905 + 1G>A variant is unclear. In this study, we investigated the prevalence of the DPYD c.1905 + 1 variants in a Turkish CRC cohort and the potential effects of these variants on fluoropyrimidine-induced hematologic side effects.Materials and Methods: The DPYD c.1905 + 1 variant was genotyped using polymerase chain reaction-restriction fragment length polymorphism analysis and confirmed by Sanger sequencing in peripheral blood samples of 100 CRC patients who received fluoropyrimidine-based chemotherapy and 60 healthy volunteers. The association of c.1905 + 1 variants with susceptibility to hematologic side effects was evaluated.Results: The DPYD c.1905 + 1G>A variant was more common in the CRC group than in the healthy control group (p = 0.001). The presence of the c.1905 + 1G>A variant was associated with thrombocytopenia (p = 0.039) and anemia (p = 0.035). CRC patients with fluoropyrimidine-induced anemia had shorter disease-free survival than CRC patients without fluoropyrimidine-induced anemia (p = 0.0009).Conclusions: Before administering fluoropyrimidine-based chemotherapy, genetic screening for the DPYD c.1905 + 1G>A variant should be performed with the aim of preventing anemia and anemia-induced complications in CRC patients.Publication Investigation of FGFR4 (Gly388Arg) gene Polymorphism in primary lung cancer Patients(Kamla-Raj Enterprises, 2015-03-01) Türe, Mehmet; Yakut, Tahsin; Deligönül, Adem; Karkucak, Mutlu; Sağ, Şebnem Özemri; Hartavi, Mustafa; Çubukcu, Erdem; Gülten, Tuna; Evrensel, Türkkan; Türe, Mehmet; Yakut, Tahsin; DELİGÖNÜL, ADEM; ÖZEMRİ SAĞ, ŞEBNEM; Hartavi, Mustafa; ÇUBUKÇU, ERDEM; Gülten, Tuna; EVRENSEL, TÜRKKAN; Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Genetik Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Onkoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/İç Hastalıkları Anabilim Dalı.; 0000-0002-9732-5340; AAJ-1027-2021; AAH-8355-2021; ECY-8582-2022; GIS-1493-2022; ESM-4544-2022; CUI-5353-2022; ETP-1691-2022; EYU-9227-2022Several studies have shown relationships between predisposition to various types of cancer and polymorphisms of the fibroblast growth factor receptor 4 (FGFR4) gene. In the present study, researchers investigated the relationship between primary lung cancer and (PLC) FGFR4 Gly388Arg polymorphism in regard to tendency, histopathologic sub-type, early onset, and metastatic status. The present study included 124 PLC patients and 100 healthy controls. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to identify gene polymorphism of FGFR4 Gly388Arg. Statistical significance was considered when p < 0.05, and a statistically significant difference was not found in FGFR-4 polymorphism between the patient group and control group in regard to tendency, histopathologic sub-type, early onset, and metastatic status (p > 0.05). The findings in this study demonstrated that there was no relationship between polymorphism of FGFR4 Gly388Arg gene and PLC. However, these results should be confirmed in larger studies and in specific histopathological sub-types of PLC.Publication Impact of systemic inflammatory markers in patients with alk -positive non-small cell lung cancer treated with crizotinib(Elsevier, 2023-11-01) Ölmez, O. F.; Bilici, A.; Gürsoy, P.; Sakin, A.; Korkmaz, T.; Çil, I.; Çakar, B.; Menekse, S.; Demir, T.; Acıkgöz, O.; Hamdard, J.; Çubukcu, Erdem; ÇUBUKÇU, ERDEM; Bursa Uludağ Üniversitesi/Tıp Fakültesi/İç Hastalıkları Anabilim Dalı.Objectives: To evaluate the prognostic utility of inflammation-based prognostic scores in patients with ALK-positive metastatic or non-resectable non-small-cell lung cancer (NSCLC) treated with crizotinib.Patients and Methods: A total of 82 patients with ALK-positive metastatic or non-resectable NSCLC who received ALK TKI crizotinib were included. Pre-treatment modified Glasgow prognostic score (mGPS), prognostic nutritional index (PNI), and systemic immune-inflammation index (SII) were calculated. Multivariable logistic regression and Cox proportional hazards models were used to assess the impact of pretreatment mGPS, PNI, and SII on overall survival (OS), progression-free survival (PFS), and objective response rate (ORR).Results: The ORR was 77.2%, while 1-year OS and PFS rates were 95.0% and 93.5%, respectively. The univariate analysis revealed significantly higher 1-year PFS (89.4 vs. 64.4%, p=0.043) and OS (92.0 vs. 83.3%, p=0.01) rates in patients with low (<934.7) vs. high (>= 934.7) SII scores. Multivariate analysis revealed that PNI >= 0.09 was a significant determinant of poorer 1-year OS rates (hazard ratio [HR]: 2.46, 95% confidence interval [CI] 0.88-4.85, p=0.035). No significant difference was observed in survival rates according to gender, age, smoking status, prior lines of therapy, or mGPS scores, while higher mGPS scores (odds ratio [OR]: 0.1, 95%CI 0.16-1.04; p=0.009) and higher PNI scores (OR: 0.16, 95% CI 0.02-0.55; p=0.035) were associated with poorer ORR.Conclusion: Our findings indicate the prognostic significance of PNI and SII in terms of survival outcome and the impact of mGPS and PNI on treatment response in patients with ALK-positive NSCLC treated with crizotinib.
