Radiofrequency Ablation Versus Stereotactic Body Radiotherapy for Recurrent Small Hepatocellular Carcinoma: A Randomized, Open-Label, Controlled Trial.

J Clin Oncol

December 2024

State Key Laboratory of Oncology in South China, Collaborative Innovation Centre for Cancer Medicine, Guangdong Provincial Clinical Research Center for Cancer, Guangdong Esophageal Cancer Institute, Guangzhou, China.

Purpose: To assess the efficacy and safety of radiofrequency ablation (RFA) versus stereotactic body radiotherapy (SBRT) in treating recurrent small hepatocellular carcinoma (HCC).

Methods: In this trial, patients with recurrent small HCC (single lesion ≤5 cm) were randomly assigned to receive either SBRT or RFA. The primary end point was local progression-free survival (LPFS), and secondary end points were progression-free survival (PFS), overall survival (OS), local control rate, and safety.

Background: Previous results of our trial demonstrated that the addition of induction chemotherapy (IC) prior to definitive chemoradiotherapy (CRT) failed to significantly improve the response rate or 3-year survival in patients with locally advanced esophageal squamous cell carcinoma (ESCC). Here, we report long-term results and exploratory analyses to further evaluate the therapeutic value of IC.

Methods: Patients with previously untreated, unresectable, stage II-IVA ESCC were randomly assigned to receive IC followed by CRT or CRT alone.

Article Synopsis
  • The study introduces a new dual-aware computed tomography ventilation imaging (CTVI) method that combines anatomical data from CT scans with motion data from Jacobian maps to enhance the accuracy of lung ventilation images used in functional lung avoidance radiotherapy (FLART).
  • Researchers utilized a dataset from 66 patients with four-dimensional CT (4DCT) images to develop a dual-path fusion network (DPFN) that processes these two types of data through specialized pathways for effective feature extraction.
  • Results indicated that the DPFN method achieved a mean Spearman's correlation coefficient of 0.70 when compared to reference ventilation images, significantly outperforming several other CTVI methods.

Electronic address:

Article Synopsis
  • The standard treatment for anal squamous cell carcinoma (ASCC) is concurrent chemoradiotherapy (CRT), but about 33% of patients still face treatment failure.
  • A study involving 100 nonmetastatic ASCC patients compared outcomes of surgery, CRT alone, and CRT with immunotherapy (CRT-I) over a median follow-up of 30.7 months, finding that CRT-I provided the best survival rates.
  • Although 26% of patients experienced severe side effects, those receiving CRT-I had the highest overall survival, with ongoing research into combining CRT with immunotherapy further improving treatment options for ASCC.

Article Synopsis
  • The EC-CRT-001 phase II study showed that combining toripalimab with chemoradiotherapy can effectively treat patients with locally advanced esophageal squamous cell carcinoma (ESCC), with a follow-up showing 3-year overall survival (OS) and progression-free survival (PFS) rates of 44.8% and 35.7%, respectively.
  • Among the 42 patients, those who did not achieve a complete clinical response (CR) had significantly worse outcomes compared to those who did, indicating the importance of achieving CR in treatment success.
  • The study also found that patients experiencing immune-related adverse events (irAEs) had higher CR rates and better PFS, suggesting a potential link between these events

The diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) is challenging due to nonspecific early symptoms, complex diagnostic processes, and small lesion sizes. This study aims to develop an automatic diagnosis method for CTEPH using non-contrasted computed tomography (NCCT) scans, enabling automated diagnosis without precise lesion annotation.A novel cascade network (CN) with multiple instance learning (CNMIL) framework was developed to improve the diagnosis of CTEPH.

Prognostic significance of PET/CT and its association with immuno-genomic profiling in oesophageal squamous cell carcinoma treated with immunotherapy plus chemoradiotherapy: results from a phase II study.

Br J Cancer

September 2024

State Key Laboratory of Oncology in South China, Collaborative Innovation Centre for Cancer Medicine, Guangdong Provincial Clinical Research Center for Cancer, Guangdong Esophageal Cancer Institute, Guangzhou, China.

Article Synopsis
  • A phase II trial showed that combining toripalimab (an anti-PD-1 antibody) with chemoradiotherapy is promising for treating locally advanced esophageal squamous cell carcinoma (ESCC), emphasizing the need for biomarkers to identify suitable patients.
  • In an analysis of 37 patients, high baseline PET/CT parameters, specifically SUV and TLG, correlated with lower treatment response and overall survival, while also indicating an immunosuppressive tumor microenvironment (TME).
  • The study suggests that monitoring these PET/CT metrics could help predict treatment outcomes and encourage further investigation into the relationship between metabolic activity and immune cell infiltration in ESCC.

Department of Thoracic Surgery and Oncology, The First Affiliated Hospital of Guangzhou Medical University, China State Key Laboratory of Respiratory Disease & National Clinical Research Center for Respiratory Disease, Guangzhou 510120, China. Electronic address:

In invasive lung adenocarcinoma (LUAD), patients with micropapillary (MIP) or solid (SOL) components had a significantly poorer prognosis than those with only lepidic (LEP), acinar (ACI) or papillary (PAP) components. It is interesting to explore the genetic features of different histologic subtypes, especially the highly aggressive components. Based on a cohort of 5,933 patients, this study observed that in different tumor size groups, LUAD with MIP/SOL components showed a different prevalence, and patients with ALK alteration or TP53 mutations had a higher probability of developing MIP/SOL components.

Epigenetic deregulation is strongly associated with tumor progression. The identification of natural tumor suppressors to overcome cancer metastasis is urgent for cancer therapy. We investigate whether myeloid/lymphoid or mixed-lineage leukemia translocated (MLLT) family members contribute to breast cancer progression and found that high MLLT6 expression predicted a better prognosis and that gradually decreased MLLT6 expression was accompanied by breast cancer malignancy.
