Complete Remission of Multiple Lung Metastases after Ablation of Hepatocellular Carcinoma by p53 Gene Therapy

A groundbreaking case study published in the Anti-Cancer Drugs journal reveals a remarkable recovery in a 68-year-old man with hepatocellular carcinoma. The research, conducted by a team of Chinese scientists, demonstrates the efficacy of combining transarterial infusion with the p53 gene and interleukin-2 in treating multiple lung metastases. This study not only highlights the potential of p53 gene therapy but also underscores the importance of multidisciplinary approaches in cancer treatment.

Key Takeaways:

  • The patient, a 68-year-old man, presented with a massive lesion in the right liver, confirmed by preoperative aspiration biopsy to be a case of moderately differentiated hepatocellular carcinoma.
  • The hepatic lesion showed complete necrosis after arterial embolization combined with microwave ablation, but the patient developed bilateral pulmonary metastases with focal diameters smaller than 1 cm.
  • Hepatic and bronchial intra-arterial infusion with the recombinant adenovirus p53 gene (rAd-p53) was performed twice, with interleukin-2 added the second time.
  • After 2 months of treatment, the bilateral pulmonary lesions had almost disappeared, and after 7 months, the lesions had disappeared completely, with no further recurrence in the lungs and liver.
  • The study highlights the potential of p53 gene therapy as a complementary approach to traditional treatments, such as ablation and infusion, in managing hepatocellular carcinoma and its metastases.
  • The patient's remarkable recovery serves as a testament to the importance of combining cutting-edge treatments with state-of-the-art medical expertise.

Statistics:

  • 68 years: the age of the patient at the time of diagnosis
  • 3 months: the duration of ablation treatment before the a-fetoprotein level increased
  • 2 months: the duration of treatment with p53 gene therapy
  • 7 months: the duration of treatment before complete remission of metastases
  • 100%: the rate of complete remission of bilateral pulmonary metastases
  • 1 cm: the focal diameter of pulmonary metastases before treatment
