Photodynamic therapy (PDT) is a minimally invasive and controllable local cancer treatment for cholangiocarcinoma (CCA). However, the efficacy of PDT is hindered by intratumoral hypoxia and the presence of an antioxidant microenvironment. To address these limitations, combining PDT with gas therapy may be a promising strategy to enhance tumor oxygenation. Moreover, the augmentation of oxidative damage induced by PDT and gas therapy can be achieved by inhibiting NRF2, a core regulatory molecule involved in the antioxidant response. In this study, an integrated nanotherapeutic platform called CMArg@Lip, incorporating PDT and gas therapies using ROS‐responsive liposomes encapsulating the photosensitizer Ce6, the NO gas‐generating agent L‐arginine, and the NRF2 inhibitor ML385, is successfully developed. The utilization of CMArg@Lip effectively deals with challenges posed by tumor hypoxia and antioxidant microenvironment, resulting in elevated levels of oxidative damage and subsequent induction of ferroptosis in CCA. Additionally, these findings suggest that CMArg@Lip exhibits notable immunomodulatory effects, including the promotion of immunogenic cell death and facilitation of dendritic cell maturation. Furthermore, it contributes to the anti‐tumor function of cytotoxic T lymphocytes through the downregulation of PD‐L1 expression in tumor cells and the activation of the STING signaling pathway in myeloid‐derived suppressor cells, thereby reprogramming the immunosuppressive microenvironment via various mechanisms.

Context: Anaplastic thyroid cancer (ATC) is a relatively rare and extensively malignant kind of thyroid carcinoma. The poor prognosis and high mortality rate of ATC can be attributed to its invasive features and undifferentiated phenotype. At present, there is a lack of efficacious therapeutic options. In light of the elevated fatality rate, it is vital to possess a comprehensive comprehension of the scientific terrain pertaining to ATC. To gather the perspectives of different researchers about the topic of ATC treatment, we did a bibliometric network analysis, which offers a comprehensive view of the scholarly literature.Methodology: A systematic search was conducted on the WoSCC database to identify publications pertaining to ATC treatment between the years 2000 and 2023. In this bibliometric investigation, the tools VOSviewers, CiteSpace, and the R package “bibliometrix” were employed to investigate the general attributes, developmental framework, and academic frontiers of the subject matter.Results: 1223 publications in total, written by 6937 scholars from 53 areas and 1402 institutions and published in 358 scholarly journals, were analyzed. There has been a gradual increase in the quantity of publications pertaining to ATC treatment. The United States and China emerged as the most prominent nations. The University of Texas MD Anderson Cancer Center and Memorial Sloan Kettering Cancer Counseling Center are prominent research institutions in highly productive countries. The journal Thyroid holds a prominent position within its discipline, being widely recognized as both the most popular and highly co-cited publication. According to the available data, Maria Cabanillas has authored the highest number of published articles, while RC Smallridge has received the highest number of co-citations. It turned out that the prevailing keywords encompassed expression, therapy, apoptosis, survival, activation, proliferation, metastasis, and other related terms. Immunotherapy, targeted therapy, and prognostic factors are the emerging research hotspots and trends.Conclusions: This paper presents a complete overview of research trends and advancements in the treatment of ATC using bibliometric analysis. The acquisition of information will offer vital insights for funding and potential creative strategies in researching the treatment of ATC, which indicates the research frontiers as well as prevalent directions in recent years.

Burkitt's lymphoma of the breast is a rare kind of malignancy, which usually occurs among women during pregnancy or breastfeeding. A rapid diffuse swelling of bilateral breasts is the most common mode of presentation. This article reports a rare case of Burkitt's lymphoma of the breast during pregnancy. The patient presented with diffuse enlargement of both breasts with skin erythema, and increased skin temperature, which brought difficulty in distinguishing it from inflammatory breast cancer and gestational mastitis. The rare clinical manifestations pose a challenge for early diagnosis, only by a series of imaging tests. Until the fine needle aspiration of breast revealed lymphoma cells and a subsequent bone marrow biopsy revealed a translocation of chromosome No.8 and No.14, the final diagnosis was ensured. Meanwhile, imaging examination indicated a huge retroperitoneal mass at a maximum diameter about 10 centimetre. It was significantly reduced together with breast lesion during the standardized chemotherapy. For a rapid progression and poor prognosis, an early diagnosis and prompt therapy are especially important for this very disease. This article provides a patient with an atypical presentation accompanied by a massive retroperitoneal neoplasm, to alert clinicians and help them learn more about this rare disease.
