    (2022) Ekinci, Ferhat; Erdogan, Atike Pinar; Yildirim, Serkan; Bulut, Gulcan; Yilmaz, Cengiz; Barutca, Sabri; 36205273
    Objective: To evaluate the utility of inflammatory prognostic index (IPI), albumin, c-reactive protein (CRP), and lactate dehydrogenase (LDH) as predictive biomarkers of oncologic outcome in metastatic renal cell cancer (mRCC) patients treated with nivolumab. Methodology: Seventy-five mRCC patients treated with nivolumab between January 2017 and June 2020 were enrolled. Several factors were retrospectively investigated, including IPI, CRP, LDH, and albumin level, for their association with progression-free survival (PFS) and overall survival (OS). The IPI was calculated as CRP x NLR/albumin. Univariate and multivariate analyses were performed to assess the prognostic value of relevant factors.Results: When analysed according to the calculated IPI score, it is seen that the group with <2.153 has an OS duration of 96.3 months, while the group with >= 2.153 has a shorter time of 42.9 months (p=0.02). In the analysis performed according to albumin level, it was reported that those with low levels (22.8 months) had worse median OS than those with high levels (92.8 months) (p=0.004). According to the cox regression analysis results, it was determined that those with a high IPI score significantly increased the risk of death compared to those with a low score (HR:2.4, p=0.023). However, this significance could not be confirmed in the multivariate analysis. It was analysed that those with low albumin levels significantly increased the risk of death compared to both Conclusion: Those with high IPI scores and low albumin levels were associated with worse median OS. However, only the multivariate analysis analysed albumin level as an independent prognostic variable. Prospective and more extensive research is needed to consolidate the potential prognostic power of these markers.

    Tyrosine kinase inhibitors in the treatment of metastatic renal cell cancer patients with early cytokine intolerance: TURCOS, a Turkish national, prospective observational study
    (2020) Benekli, Mustafa; Gumus, Mahmut; Ozkan, Metin; Dane, Faysal; Elkiran, Emin T.; Cicin, Irfan; Sevinc, Alper; Aliustaoglu, Mehmet; Isikdogan, Abdurrahman; Meydan, Nezih; Oksuzoglu, Berna; Ozyilkan, Ozgur; Artac, Mehmet; Ozdemir, Feyyaz; Kilickap, Sadettin; 0000-0001-8825-4918; 33050804; AAD-2817-2021
    Objective Cytokines have been the mainstay of treatment in metastatic renal cell cancer (mRCC) for decades before the introduction of tyrosine kinase inhibitors (TKIs), which dramatically changed the therapeutic landscape in these patients. This observational study was designed to evaluate use of TKIs in the treatment of cytokine-intolerant mRCC patients. Methods A total of 151 cytokine-intolerant mRCC patients who were treated with TKIs (sunitinib, pazopanib and sorafenib) were enrolled in this prospective, non-interventional, multi-center observational study at 16 oncology centers across Turkey. Mean (SD) age was 61.3 (11.1) years and 74.8% were males. Data on duration of TKI treatment was the primary outcome measure. Additionally, overall response rate (ORR), progression free survival (PFS), overall survival (OS) and safety data were recorded. Results Median duration of treatment was 8.2 months at a median follow up of 17.9 months. ORR and disease control rate were 12.5% and 70.8%, respectively. Median PFS and OS were 7.5 months (95%CI: 6.4-10.4) and 27.3 months (95%CI: 17.6-27.3) with no significant difference among three TKI agents in terms of treatment duration, ORR, PFS and OS. The most common adverse events excluding progression-which was the protocol requirement were diarrhea (13.6%), asthenia (13.6%) and hand-foot syndrome (12.6%). Dose modifications were required in 30.5% of the patients and 15% discontinued TKIs because of toxicity. Conclusions Our findings confirm the efficacy and safety profile of TKIs in the first-line treatment of mRCC patients intolerant to cytokine treatment. There was no significant difference among three TKI agents in terms of treatment duration, ORR, PFS and OS.

    A national, multicenter, non-interventional, observational study on treatment patterns in patients with metastatic renal cell carcinoma in Turkey - NOTES study
    (2018) Ozyilkan, Ozgur; Yalcin, Suayib; Yildiz, Ramazan; Dane, Faysal; Karaoglu, Aziz; Oksuzoglu, Berna; Sevinc, Alper; Ozdemir, Feyyaz; Turna, Hande; Uslu, Ruchan; Ulay, Esat; 0000-0001-8825-4918; 29551901; AAD-2817-2021
    Introduction: The introduction of targeted therapies in renal cell carcinoma has significantly improved its prognosis and treatment outcomes in recent years. Such treatment options are targeted therapies of the vascular endothelial growth factor (VEGF) pathway and the mammalian target of the rapamycin pathway. With the use of tyrosine kinase inhibitors (TKIs) and mammalian target of the rapamycin inhibitors, overall survival has increased up to 2 years. In Turkey, due to applicable reimbursement conditions for patients with metastatic renal cell carcinoma (mRCC), interferon use is mandated as a first-line treatment, thus providing information on the use of everolimus only after initial interferon and second-line VEGF-targeted treatments such as VEGF-TKI. Patients and methods: To provide a first real-life data set in Turkey, we conducted a prospective, non-interventional, observational study and assessed the efficacy and safety of everolimus after two lines of treatment including interferon. A total of 100 patients with histologically confirmed mRCC were enrolled in the study from 11 centers between June 2012 and March 2014 (70 males and 30 females). Efficacy was assessed on the basis of progression-free survival and overall survival; safety of everolimus was assessed on the basis of adverse event occurrence. Results: The study results showed that the median progression-free survival with everolimus treatment was 8.1 months (95% CI: 5.1-11.1) and the median overall survival was 17.6 months (95% CI: 10.1-25.1), thus indicating a better overall response based on survival durations than those from the randomized Phase III REnal Cell cancer treatment with Oral RAD001 given Daily study results (4.9 and 14.8 months, respectively). Conclusion: The study showed that everolimus treatment is a safe and effective treatment option in the treatment of mRCC after VEGF-TKI, with an acceptable safety and tolerability profile in real-life settings.
