FABP5 promotes lymph node metastasis in cervical cancer by reprogramming fatty acid metabolism

Background and Objectives: In October 2018, the International Federation of Gynecology and Obstetrics (FIGO) revised its classification of advanced stages of cervical cancer. The main points of the classification are as follows: stage IIIC is newly established; pelvic lymph node metastasis is stage IIIC1; and para-aortic lymph node metastasis is stage IIIC2. Currently, in Japan, radical hysterectomy is performed in advanced stages IA2 to IIB of FIGO2014, and concurrent chemoradiotherapy (CCRT) is recommended for patients with positive lymph nodes. However, the efficacy of CCRT is not always satisfactory. The aim of this study was to compare postoperative adjuvant chemotherapy (CT) and postoperative CCRT in stage IIIC1 patients. Materials and Methods: Of the 40 patients who had undergone a radical hysterectomy at Iwate Medical University between January 2011 and December 2016 and were pathologically diagnosed as having positive pelvic lymph nodes, 21 patients in the adjuvant CT group and 19 patients in the postoperative CCRT group were compared. Results: The 5 year survival rates were 77.9% in the CT group and 74.7% in the CCRT group, with no significant difference. There was no significant difference in overall survival or progression-free survival between the two groups. There was no significant difference between CT and CCRT in postoperative adjuvant therapy in the new classification IIIC1 stage. Conclusions: The results of the prospective Japanese Gynecologic Oncology Group (JGOG) 1082 study are pending, but the present results suggest that CT may be a treatment option in rural areas where radiotherapy facilities are limited.

(1) This study investigated the prognostic impact of tumor size in patients with metastatic cervical cancer. (2) Methods: Seventy-three cervical cancer patients in our institute were stratified into two groups based on distant metastasis: para-aortic lymph node metastasis alone (IIIC2) or spread to distant visceral organs with or without para-aortic lymph node metastasis (IVB) to identify primary tumor size and concurrent chemoradiotherapy. (3) Results: The overall survival (OS) for patients with a tumor >6.9 cm in size was significantly poorer than that for patients with a tumor ≤6.9 cm in the IVB group (p = 0.0028); the corresponding five-year OS rates in patients with a tumor ≤6.9 and >6.9 cm were 53.3% and 13.4%, respectively. In the multivariate analysis, tumor size and primary treatment were significantly associated with survival in metastatic cervical cancer. (4) Conclusions: Tumor size ≤6.9 cm and concurrent chemoradiotherapy as the primary treatment were favorable prognostic factors for patients with metastatic cervical cancer.

Abstract Background Cervical cancer is a serious disease with complicated pathogenesis and thus there is an urgent need to find novel targets for the treatment. Recently, long non-coding RNAs (lncRNAs) have emerged as critical factors in tumorigenesis. In this study, we aimed to investigate the mechanism of HAND2 antisense RNA 1 (HAND2-AS1) on the invasion and metastasis of cervical cancer cells. Methods The expression patterns of HAND2-AS1, microRNA-330-5p (miR-330-5p) and leucine zipper down-regulated in cancer 1 (LDOC1) in cervical cancer were characterized by RT-qPCR and western blot analysis. Dual luciferase reporter assay and RIP were applied to verify relationship between HAND2-AS1, miR-330-5p and LDOC1. Fluorescence in situ hybridization (FISH) was used to detect the subcellular localization of HAND2-AS1. Besides, viability, invasion and migration ability of HeLa cells were investigated by cell counting kit-8 (CCK-8) and Transwell assays respectively. Hematoxylin–eosin staining was performed for lymph node metastasis detection. In addition, the tumor growth in nude mice was evaluated. Results Low expression of HAND2-AS1 and LDOC1, and high expression of miR-330-5p were detected in cervical cancer tissues and cells. It was found that binding of HAND2-AS1 to miR-330-5p results in upregulation of LDOC1 expression. Also, overexpressed HAND2-AS1 and LDOC1 or down-regulated miR-330-5p inhibited expression of proliferation-associated proteins Ki-67, PCNA, migration-associated proteins N-cad and invasion-related proteins MMP-2, MMP-9 as well as lymph node metastasis. Moreover, HAND2-AS1 inhibited tumor formation and lymph node metastasis by binding to miR-330-5p in vivo. Conclusion HAND2-AS1 promotes LDOC1 expression by competitively binding to miR-330-5p and consequently inhibiting cervical cancer cell invasion and metastasis. This could facilitate development of therapeutic strategies against cervical cancer.
