ÖZ: Amaç: Bu çalışmada, evre 3-5 Kronik böbrek hastalarında (KBH) vitamin D replasmanının CD3+, CD4+, CD8+ ve CD14+ hematopoietik hücre alt gruplarındaki vitamin D reseptör (VDR) yüzdesi ile inflamatuar belirteçlerle ilişkisini değerlendirmeyi amaçladık. Yöntem: Bu prospektif çalışmada evre 3-5 KBH’sı olan; tahmini glomerüler filtrasyon hızı (tGFH) ≤60ml/dk/1,73m2 olan 81 hasta katıldı. Serum kreatinin, tGFH, intakt parathormon (iPTH), 25 OH vitamin D düzeyleri, CRP, nötrofil, lenfosit değerleri ve CD3+, CD4+, CD8+, CD14+ hematopoietik hücrelerde VDR yüzdeleri hesaplandı. Hastalar, 25 OH VD3 düzeylerine göre Vitamin D eksikliği tanısıyla (<20 ve ≥20 ng/dl) iki gruba, KBH evrelerine göre (evre 3-5) üç gruba, D vitamini kullanımı durumuna göre (kullanmıyor, kalsitriol veya 25 OH vitamin D) üç gruba ayrıldı. Bulgular: Vitamin D eksikliği tanısıyla iki gruba ayrılan hastalarda aktif D vitamini kullanımı, kreatinin, tGFH ve iPTH düzeyleri arasında istatistiksel anlamda fark tespit edildi (p:0,04, p:0,008, p:0,02 ve p:0,002). CRP ve nötrofil /lenfosit oranı arasında istatistiksel fark tespit edilmedi (p:0,95, p:0,63). Hastaları KBH evrelerine göre gruplandırdığımızda iPTH düzeylerinde istatistiksel fark tespit edildi (p:0,001). Hastaları D vitamini kullanımı durumuna göre üç gruba ayırdığımızda kreatinin, tGFH, iPTH ve 25 OH vitamin D3 düzeyleri arasında istatistiksel fark tespit edildi (p:0,00, p:0,00, p: 0,02 ve p:0,006). CD3 +, CD4 +, CD8 +, CD14 + hematopoietik hücrelerde VDR yüzdeleri arasında bir fark tespit edilmedi (p:0,17, p:0,15, p:0,14, p:0,31). Lenfosit düzeyleriyle tGFH değerleri arasında istatistiksel bir korelasyon vardı (r:0,28, p:0,011). Lenfosit düzeyleriyle CD8+ hücrelerin VDR yüzdesi değerleri arasında istatistiksel bir korelasyon vardı (r:0,224, p:0,046). Sonuç: Replasman tedavileri ile VDR yüzdelerinin tüm evrelerde benzer oranlarda tutulabileceği, inflamasyonda azalma sağlanmış olabileceğinden kaynaklı olabilir. ANAHTAR KELİMELER: İnflamasyon, Kronik Böbrek Hastalığı, Vitamin D, Vitamin D Reseptör Düzeyi

We present a case of concomitant c-ros oncogene 1 (ROS1) and anaplastic lymphoma kinase (ALK) and fusion in non small cell lung cancer (NSCLC) in a 59-year-old patient and review the treatment efficacy of co-mutations. The choice of the treatment and its effectiveness with rare co-mutations is a subject of considerable interest. This review will provide clues to the optimal treatment approach to NSCLC patients with more than one driver mutations. However, randomized studies are needed to clarify which patients with concurrent mutations may benefit from chemotherapy or related tki.

202 Background: The optimal treatment for metastatic colorectal cancer (mCRC) after the second line is still controversial. Regorafenib (Reg) revealed promising results by improving overall survival compared to best supportive care. However, in real-world practice rechallenge chemotherapy (CTr) is often preferred even though supporting evidence is not enough. We aim to compare the efficacy of regorafenib and 5-fluorouracil-based (5-FU) rechallenge treatment in the third line setting of mCRC. Methods: In this retrospective multi-institutional trial, mCRC patients from 21 centers in Turkey progressing after 2 lines of chemotherapy between 2012-2020 were analyzed. Patients who were treated with Reg or rechallenge therapy in the third-line setting were eligible. Rechallenge chemotherapy was identified as the re-use of the 5-FU based regimen which was administered in one of the previous treatment lines. Overall survival (OS), objective response rate (ORR), progression free survival (PFS) and toxicity were analyzed. Chi-square, Kaplan-Meier method and Cox regression analysis were used for analysis. Results: The clinical data of 441 mCRC patients were analyzed. Of these, 284 received regorafenib while 156 received rechallenge chemotherapy. The mean age was 57 and 56% was male. Median OS since the diagnosis was better with CTr than with Reg (48 months (95% CI, 43.4–52.6) vs. 39 months (95% CI, 35.4–42.5), p<0.001). Median OS after the third-line treatment was 12.0 (95% CI, 9.9–14) and 9.0 months (95% CI, 7.5–10.4) for CTr and Reg groups, respectively (p<0.001). PFS was 6 months for patients receiving CTr and 4 months for those treated with Reg (p = 0.139). ORR was significantly higher in CTr group than Reg (p<0.001). BRAF status, MSI status and treatment type (CTr vs. Reg) are factors found associated with OS in Cox regression analysis (p<0.001, p=0.021 and p<0.001, respectively). Adverse effects were seen in 82% and 68.2% of patients receiving Reg and CTr, respectively. Discontinuation of treatment due to adverse effects was higher in patients treated with Reg (10% vs. 2.5%). Conclusions: Our analysis revealed that rechallenge is an appreciated option, in both efficacy and toxicity, when the limited treatment options for mCRC is considered. Although regorafenib treatment contributes to survival, CTr shows better disease control. Our study has the highest number of patients in the literature. Still, prospective studies are mandatory for validation of CTr in the third-line treatment of mCRC.
