Abstract PDF PubReader ePub: Although the efficacy of surgery followed by taxane- and platinum-based systemic chemotherapy has been clearly demonstrated in the standard first-line treatment of epithelial ovarian cancer, the role of radiation therapy for distant lymph node metastasis in patients with epithelial ovarian cancer is not well-established due to a lack of reported studies. We identified four patients who underwent selective adjuvant radiation therapy for neck and para-aortic lymph node lesions after primary debulking surgery between 2020 and 2022, followed by platinum-based chemotherapy for stage 4B high-grade serous ovarian cancer. Through a retrospective review of medical records, we analyzed patient clinicopathologic features, treatment course, and imaging findings. The median age was 49.25 years (range, 46–54 years). All patients had the International Federation of Gynecology and Obstetrics stage 4B disease. Following primary debulking surgery, all patients received weekly paclitaxel-carboplatin chemotherapy and maintenance treatment with poly(ADP-ribose) polymerase (PARP) inhibitors. All patients received selective adjuvant radiation therapy for neck and para-aortic lymph node metastasis before PARP inhibitor maintenance. The median follow-up time was 36.75 months (range, 19–45 months). All patients achieved a complete response. None of the patients experienced disease recurrence or died during the follow-up period. The management of distant lymph node metastasis in patients with epithelial ovarian cancer remains a matter of debate. Selective adjuvant radiation therapy in first-line treatment for ovarian cancer appears to be a feasible approach with maintenance therapy for stage 4B epithelial ovarian cancer.

Abstract Objective

The imbalance between pro-inflammatory and anti-inflammatory cytokines may underlie different pain states. Although ascorbic acid is the most important physiological antioxidant that affects host defense mechanisms and immune homeostasis, there is limited information on the effects of ascorbic acid on the production of cytokines.

Methods

In this study, we investigated the in vitro effect of L-ascorbic acid (AA) on the production of pro-inflammatory and anti-inflammatory cytokines by stimulating C57BL/6 mouse splenocytes with the polyclonal activators lipopolysaccharide or concanavalin A.

Results

AA significantly downregulated the expression of IL-6, IL-12, and TNF-α at 48 h and 72 h in mouse splenocytes treated with a combination of polyclonal activators and AA. AA treatment also resulted in upregulation of IL-4 and IL-10 at 72 h. These findings demonstrated that AA significantly potentiated production of anti-inflammatory cytokines whereas there was an inverse association between AA and expression of pro-inflammatory cytokines in mouse splenocytes.

Conclusion

AA may have potential applications in the reduction of inflammatory pain because of its function in modulating the production of cytokines. However, further in vivo investigations are necessary to elucidate the mechanisms involved.
