Abstract： Objective: The current treatment for early-stage neuroendocrine carcinoma of the cervix (NECC) mainly relies on operation and chemotherapy. We want to evaluate values of postoperative radiation in early-stage NECC.
Methods: Retrospective cohort study. Early-stage NECC patients from 2006 to 2022 in our hospital were included. Depending on whether received postoperative radiation, the patients were divided into Postoperative non-radiation group (Group A) and Postoperative radiation group (Group B). We use Kaplan-Meier method to analyze the progression-free survival (PFS), overall survival (OS), recurrence and OS rate.
Results: Sixty-six cases were included, 32 (48.5%) in Group A and 34 (51.5%) in Group B. After 35 (range 12-116) months follow-up, 26 (39.4%) had recurrence. Compared with Group A, Group B had lower pelvic recurrence rate (12.5% vs 2.9%, p = 0.142), higher distant recurrence rate (28.1% vs 44.1%, p = 0.177), and similar mortality rate (29.4% vs 31.3%, p = 0.871). Cervical stromal invasion ≥1/2 was more common in Group B (28.0% vs 63.0%, p = 0.012). Postoperative radiation in patients with cervical stromal invasion ≥1/2 showed an extended trend in PFS (33.9 months vs 47.9 months) and OS (40.7 months vs 70.0 months) but without statistical difference (p = 0.963, p = 0.636). Lymph-vascular space invasion (LVSI) is a high-risk factor for tumor recurrence (HR 9.13, p = 0.005), but radiation after surgery did not improve the PFS (51.5 months vs 48.8 months, p = 0.942) and OS (53.9 months vs 60.6 months, p = 0.715) in patients with LVSI.

Abstract： [Purpose/Significance] The technical patent in the field of library is an important representation of the technical development of library. It is used as the unit of measurement to form one of the important dimensions to observe the overall development and reform of library. By combing the evolution of patents in the field of library, we can better explore and grasp the law of library development.[Method/Process] This paper analyzed the time, patentee, subject distribution and change law of patents in the field of library, and compared them with the multiple dimensions of library development policies and library research literatures.[Result/Conclusion] Based on the analysis of library related patents, it is found that the related technologies are mainly oriented to "physical books" and "convenient librarians' daily application". In recent years, more and more attention has been paid to the "user" scenario, and the artificial intelligence technology has also increased rapidly in recent years. In the multi-dimensional comparison of library development, themes in related fields at the levels of technology, research and policy show asynchrony.
