Department of Radiation Oncology, Jinling Hospital, Medical School of Nanjing University, Nanjing, China.

Purpose: This study aimed to evaluate the efficacy and safety of trans-arterial chemoembolization (TACE) followed by stereotactic body radiation therapy (SBRT) in treating Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC) not amenable to resection and radiofrequency ablation (RFA).

Methods: From February 2012 to January 2017, a total of 57 BCLC stage B HCC patients who were unsuitable candidates for resection and RFA treated with TACE combined with CyberKnife SBRT were included in this retrospective study. Patients underwent TACE for a median of two times (1-5 times) before SBRT. SBRT prescription doses ranged from 30 Gy to 50 Gy in 3-5 fractions.

Results: The median follow-up time was 42 months. The objective response rate (CR + PR) was 85.9%, and the disease control rate (CR + PR + SD) was 96.5%. The local control (LC) rates were 91.1% and 84.3% at 1 and 2 years, respectively. The 1-, 2-, 3-year overall survival (OS) and the median survival time were 73.2%, 51.4%, 32.4% and 26.6 months, respectively. The 1-, 2-, and 3-year progression-free survival (PFS) were 34.2%, 21.6%, and 9%, respectively, with a median PFS time of 9.7 months. A subgroup analysis was conducted in 32 patients with AFP ≥ 200 ng/ml before TACE. OS was significantly prolonged in those with AFP that decreased by more than 75% than those with AFP that decreased by less than 75% (P = 0.018) after SBRT. The treatment was well tolerated with only one patient (1.8%) developed grade 3 gastrointestinal toxicity, and another patient developed non-classical RILD. In multivariate analysis, tumor length ≥ 10 cm and AFP ≥ 200 ng/ml were independent poor prognostic factors for OS.

Conclusion: The combination of TACE and Cyberknife SBRT showed optimal efficacy with acceptable toxicity for BCLC stage B HCC.

Combined inhibition of AURKA and HSF1 suppresses proliferation and promotes apoptosis in hepatocellular carcinoma by activating endoplasmic reticulum stress.

Cell Oncol (Dordr) 2021 Jun 26. Epub 2021 Jun 26.

The Affiliated Cancer Hospital of Nanjing Medical University, Jiangsu Cancer Hospital, Jiangsu Institute of Cancer Research, 42 Baiziting, Nanjing, Jiangsu, 210009, China.

Purpose: In this study we aimed to assess the anti-tumor effect of co-inhibition of Aurora kinase A (AURKA) and heat shock transcription factor 1 (HSF1) on hepatocellular carcinoma (HCC), as well as to explore the mechanism involved.

Methods: Expression of AURKA and HSF1 in primary HCC tissues and cell lines was detected by immunohistochemistry (IHC), qRT-PCR and Western blotting. AURKA was knocked down in HepG2 and BEL-7402 HCC cells using lentivirus-mediated RNA interference. Next, CCK-8, clone formation, transwell and flow cytometry assays were used to assess their viability, migration, invasion and apoptosis, respectively. The expression of proteins related to cell cycle progression, apoptosis and endoplasmic reticulum stress (ERS) was analyzed using Western blotting. In addition, in vivo tumor growth of HCC cells was assessed using a nude mouse xenograft model, and the resulting tumors were evaluated using HE staining and IHC.

Results: Both AURKA and HSF1 were highly expressed in HCC tissues and cells, while being negatively related to HCC prognosis. Knockdown of AURKA significantly inhibited the colony forming and migrating capacities of HCC cells. In addition, we found that treatment with an AURKA inhibitor (Danusertib) led to marked reductions in the proliferation and migration capacities of the HCC cells, and promoted their apoptosis. Notably, combined inhibition of AURKA and HSF1 induced HCC cell apoptosis, while increasing the expression of ERS-associated proteins, including p-eIF2α, ATF4 and CHOP. Finally, we found that co-inhibition of AURKA and HSF1 elicited an excellent in vivo antitumor effect in a HCC mouse model with a relatively low cytotoxicity.

Conclusions: Combined inhibition of AURKA and HSF1 shows an excellent anti-tumor effect on HCC cells in vitro and in vivo, which may be mediated by ERS. These findings suggest that both AURKA and HSF1 may serve as targets for HCC treatment.

Concurrent chemoradiotherapy with raltitrexed and nedaplatin regimen for esophageal squamous cell carcinoma.

Medicine (Baltimore) 2020 Jan;99(4):e18732

Department of Radiation Oncology, Jinling Hospital, Medical School of Nanjing University, Nanjing, PR China.

Background: The aim of the study reported here was to evaluate the feasibility and safety of raltitrexed and nedaplatin with concurrent radiotherapy in patients with unresectable, locally advanced esophageal squamous cell carcinoma (ESCC).

Methods: Eligible patients were adults with newly diagnosed untreated, unresectable esophageal cancer in stages I to IV with lymph node metastases or cervical esophageal cancer. Patients received nedaplatin 25 mg/m per day on day 1-3, raltitrexed 3 mg/m on days 1 repeated every 21 days for 2 cycles, and combined concurrent radiotherapy (2 Gy/fraction, total dose of 60 Gy).

Result: Thirty patients were included with squamous cell carcinoma. The median follow-up duration was 24 months. The overall response rate was 90%. The 1-year and 2-year overall survival rates for all patients were 70.4% and 55.7% with a median survival time of 30 months, and the median progression free survival was 20 month. The major toxicities were leukopenia and thrombopenia, with grade 3 to 4 leukopenia and thrombopenia were 50% and 30% of patients.

Conclusion: Concurrent chemoradiotherapy with raltitrexed and nedaplatin agents frequently caused myelosuppression but was highly active and suggested to be a promising treatment option for locally advanced ESCC.
