Estrogen Inhibits Epithelial Progesterone Receptor-Dependent Progestin Therapy Efficacy in a Mouse Model of Cervical Cancer

Antitumor progestins activity: Cytostatic effect and immune response

Progestins are used to treat some hormone-sensitive tumors. This review discusses the mechanisms of progestins' effects on tumor cells, the differences in the effects of progesterone and its analogs on different tumor types, and the influence of progestins on the antitumor immune response. Progestins cause a cytostatic effect, but at the same time they can suppress the antitumor immune response, and this can promote the proliferation and metastasis of tumor cells. Such progestins as dienogest, megestrol acetate and levonorgestrel increase the activity of NK-cells, which play a major role in the body's fight against tumor cells. The use of existing progestins and the development of new drugs with gestagenic activity may hold promise in oncotherapy.

Crosstalk between ferroptosis and steroid hormone signaling in gynecologic cancers

Ferroptosis is a novel types of regulated cell death and is widely studied in cancers and many other diseases in recent years. It is characterized by iron accumulation and intense lipid peroxidation that ultimately inducing oxidative damage. So far, signaling pathways related to ferroptosis are involved in all aspects of determining cell fate, including oxidative phosphorylation, metal-ion transport, energy metabolism and cholesterol synthesis progress, et al. Recently, accumulated studies have demonstrated that ferroptosis is associated with gynecological oncology related to steroid hormone signaling. This review trends to summarize the mechanisms and applications of ferroptosis in cancers related to estrogen and progesterone, which is expected to provide a theoretical basis for the prevention and treatment of gynecologic cancers.

Construction of Nursing Practice Model in Case Management of Concurrent Chemotherapy and Radiochemotherapy Treatment in Cervical Cancer

Objective

To construct a case management model of synchronous radiotherapy and concurrent chemotherapy and radiochemotherapy (CRR) for cervical cancer led by nurses and carry out preliminary implementation and evaluation, so as to explore a new model of nursing practice.

Methods

Totally 80 cervical cancer patients were included in this study, 43 patients were in the experimental group, and 37 patients were in the control group. The clinical data, side effects, psychological reactions, and nutritional indexes were collected before and after the intervention.

Results

The results of Hospital Anxiety and Depression Scale (HADs) showed that anxiety and depression scores decreased after intervention in the experimental group, and the difference between two groups had significant after intervention (P < 0.05). Serum fatty acids, albumin, and cholesterol in the experimental group were decreased after the intervention. Moreover, the incidence of radiation vaginitis and radiation dermatitis had significant differences between the two groups (P < 0.05).

Conclusion

The case management nursing practice mode of concurrent radiotherapy and chemotherapy for cervical cancer can effectively promote the self-management of risk factors, reduce the occurrence of complications, and improve the ability of self-care.
