    Advancing hepatocellular carcinoma treatment with hepatic arterial infusion chemotherapy
    (Baishideng Publishing Group Inc, 2024) Yildirim, Eda Caliskan; Ergun, Yakup
    Hepatocellular carcinoma (HCC) remains a major challenge in oncology, being a leading cause of cancer-related mortality worldwide. Early-stage HCC is typically treated with surgical resection, transplantation, or ablation, while advanced-stage HCC relies on systemic therapies like sorafenib and newer combinations such as atezolizumab-bevacizumab. Despite these advancements, there is still a need for effective treatments for unresectable HCC, especially in cases with macroscopic vascular invasion. Hepatic arterial infusion chemotherapy (HAIC) has demonstrated promising outcomes in Asia for the treatment of unresectable HCC, yet its application in Western countries has been relatively limited. This letter reviews the recent meta-analysis by Zhou et al published in the World Journal of Gastrointestinal Oncology, which demonstrates the efficacy and safety of HAIC vs sorafenib. The analysis includes 9 randomized controlled trials and 35 cohort studies, highlighting significant improvements in overall survival, progression-free survival, and objective response rates with HAIC and its combinations. The editorial explores the reasons behind the limited use of HAIC in Western countries. It underscores the potential of HAIC to enhance treatment outcomes for advanced HCC and calls for more research and broader adoption of HAIC in clinical practice globally.

    KRAS codon 12 and 13 mutations may guide the selection of irinotecan or oxaliplatin in first-line treatment of metastatic colorectal cancer
    (Taylor & Francis As, 2019) Ergun, Yakup; Acikgoz, Yusuf; Bal, Oznur; Ucar, Gokhan; Dirikoc, Merve; Yildirim, Eda Caliskan; Akdeniz, Nadiye
    Background: In this study, we aimed to investigate the frequency, prognostic effect of codon, and amino acid-specific KRAS mutations in patients with metastatic colorectal cancer (mCRC) and their predictive effect on irinotecan and oxaliplatin during first-line treatment. Methods: The data of 304 mCRC patients were retrospectively evaluated between 2010 and 2018. Patients were categorized according to the most prominent codon and amino acid mutation and their prognostic features were analyzed. Results: In total, 274 patients were included in the study and 128 patients (47%) revealed KRAS mutation. Median follow-up time was 19.8 months (range; 1.6-96). The median overall survival rates for patients with codons 12 and 13 mutations were 25.4 and 22.2 months, respectively (p = 0.4). Moreover, the median overall survival for the codon 12 mutant patients who received irinotecan-based chemotherapy in the first-line treatment was 42.7 months, whereas for the codon 13 mutant and KRAS wild-type patients, it was 18.3 and 23.9 months, respectively (codon 12 vs. codon 13; HR: 0.31, p = 0.03, codon 12 vs. wild-type; HR: 0.45, p = 0.03). Conclusion: The significant survival advantage was observed in patients with codon 12 mutations who received irinotecan-based chemotherapy as a first-line treatment.
