    Purpose: After failure of the first-line sorafenib treatment in advanced or metastatic stage hepatocellular carcinoma (HCC), regorafenib is one of the newly-approved targeted agents. We aimed to evaluate the efficacy of regorafenib in patients with advanced HCC treated in the secondor third-line setting. Methods: In this retrospective and multicenter study, advanced HCC patients not eligible for local therapies, who received a secondor third-line regorafenib therapy after progression on the first-line sorafenib or sequential therapy with chemotherapy (CT) followed by sorafenib, were included. Results: In the first-line setting, 28 (28.9%) patients received CT and 69 (71.1%) patients received sorafenib. There were 24 (24.7%) patients who were intolerant to sorafenib. Disease control rate (DCR) was 53.6% for all patients treated with regorafenib, 62.3% in patients who received regorafenib in the second-line, and 32.1% for those receiving regorafenib in the third-line (p=0.007). Median progression-free survival (PFS) and overall survival (OS) were 5.6 (range; 4.3-6.9) and 8.8 (range, 6.3-11.3) months for all patients treated with regorafenib vs. 7.1 months and 10.3 months for patients who received regorafenib in the second-line vs. 5.1 and 8.7 months for patients who received regorafenib in the third-line, respectively; however, there was no statistically significant difference (p(PFS)=0.22 and p(OS)=0.85). Conclusion: Although receiving CT as a first-line therapy in advanced HCC patients did not affect the survival rates of subsequent regorafenib therapy, it might diminish the DCR of regorafenib.

    Major and minor salivary gland cancers: A multicenter retrospective study
    (Wiley, 2023) Hacioglu, Muhammet Bekir; Erdogan, Bulent; Bardakci, Murat; Algin, Efnan; Gulbagci, Burcu; Hacibekiroglu, Ilhan; Hamdard, Jamshid
    BackgroundMost of the studies on salivary gland cancers are limited for various reasons such as being single-center, small number of patients, including only major or minor SGCs, or only including epidemiological data. MethodsA total of 37 medical oncology clinics from different regions of Turkey participated in this retrospective-multicenter study. The analyzed data included clinical and demographical features, primary treatment, metastasis localizations, and treatments and includes certain pathologic features. ResultsThe study included data from a total of 443 SGCs. 56.7% was in major salivary glands and 43.3% was in minor salivary glands. Distant metastasis in the major SGCs was statistically significantly more common than in the minor SGCs, locoregional recurrence was statistically significantly more common in the minor SGCs than in the major SGCs (p = 0.003). ConclusionsEpidemiological information, metastasis and recurrence patterns, treatment modalities, and survival analysis of the patients over 20 years of follow-up are presented.
