The concomitant of non-classical stereotactic body radiotherapy with tislelizumab based on multidisciplinary modalities for leiomyosarcoma: A case report

BACKGROUND

Stereotactic body radiotherapy (SBRT) and immune checkpoint inhibitors (ICIs) could obtain a certain synergistic effect on bone and soft tissue sarcoma (BSTS). Given its low radiosensitivity, BSTS usually require an irradiation dose >65 Gy to achieve local control. Herein, we developed a non-classical SBRT technique called "onion-shaped simultaneous boost (OSB)," and reported a patient with prostatic leiomyosarcoma which received non-classical SBRT and other systemic treatments.

METHODS

In the case, a 49-year-old male patient was diagnosed with prostatic leiomyosarcoma in November 2018. In the radiotherapy plans, the maximum doses of the targets were more than 65 Gy, while the doses of the organs at risk (OARs) were strictly limited.

RESULTS

After receiving radiotherapy, ICI, and other multidisciplinary modalities, the patient achieved partial response (PR).

CONCLUSION

In this clinical case, we have observed that the OSB technique, which employs an increased per-fraction radiotherapy dose without the need to match the single-fraction doses typical of conventional SBRT, effectively enhances the therapeutic impact on leiomyosarcoma without an increase in radiotherapy-related side effects. By integrating the OSB technique with a multidisciplinary array of antineoplastic strategies, we can more effectively manage sarcomas in clinical practice.

Research trend of lung cancer epigenetics research: Bibliometric and visual analysis of top-100 cited documents

Background

Lung cancer is a highly prevalent cancer on a global scale and its oncogenic process is driven by the accumulation of multiple pathological events. Epigenetics has gained significant recognition in recent years as a crucial contributor to the development of lung cancer. Epigenetics include processes such as DNA methylation, histone modification, chromatin remodeling, and RNA modification. These pathways lead to enduring alterations in genetic phenotypes, which are crucial in the advancement and growth of lung cancer. However, the specific mechanisms and roles of epigenetics in lung cancer still need to be further elucidated.

Methods

We obtained publications from the Web of Science databases and applied a rigorous search method to filter them. Ultimately, we gathered high-quality publications that had received the highest 100 number of citations. The data were processed and visualized by various bibliometric tools.

Results

The 100 papers had varying numbers of citations, with the lowest being 491 and the most being 6316. On average, each work received 1119 citations. A total of 1056 co-authors were involved in publishing these papers in 59 journals from 185 institutions in 27 countries. The majority of high-caliber research in the subject of lung cancer epigenetics is conducted in advanced countries, with the United States taking the lead in terms of both the quantity of articles produced and their academic influence. The study of DNA methylation has been a longstanding research priority in the discipline. With the development of next-generation sequencing technology in recent years, research related to non-coding RNA has become a research hotspot. Future research directions may focus more on exploring the mechanisms of action of messenger RNA and circular RNA and developing targeted treatment strategies based on non-coding RNA drugs.

Conclusion

We analyzed 100 top lung cancer and epigenetics documents through various bibliometric analysis tools. This study provides a concise overview of the findings from prior research, anticipates future research directions, and offers potential avenues for additional investigation.
