RESUMO

OBJECTIVE: The aim of this study was to compare the surgical outcomes of robotic-assisted radical hysterectomy (RRH) with traditional laparoscopic radical hysterectomy (TLRH) for the treatment of early-stage cervical cancer in a large retrospective cohort of a total of 933 patients. METHODS: We have enrolled 100 patients into the RRH and 833 patients into the TLRH group. The surgical outcomes include operating time, blood loss, transfusion rate, pelvic lymph node yield, hospitalization days, duration of bowel function recovery, catheter removal before and after 3 weeks, conversion to laparotomy, and intraoperative and postoperative complications. Follow-up results were also analyzed for all patients. RESULTS: Both groups have similar patient and tumor characteristics but patients with a larger lesion size were preferably enrolled in the TLRH treatment group. The treatment with RRH was generally superior to TLRH with respect to operating time, blood loss, length of hospitalization, duration of bowel function recovery, and postoperative complications. On follow-up of patients, there were no relapses reported in the RRH group compared with 4% of relapse cases and 2.9% of deaths because of metastasis in the TLRH group. No conversion of laparotomy occurred in the RRH group. No significant difference was found with respect to intraoperative complications and blood transfusion between both groups. CONCLUSIONS: The results from this study suggest that RRH is superior to TLRH with regard to surgical outcome and may pose a safe and feasible alternative to TLRH. The operating time and lymph node yield is acceptable. Our study is one of the largest single-center studies of surgical outcomes comparing RRH with TLRH during cervical cancer treatment and will significantly contribute to the safety of alternative treatment options for patients. Furthermore, the difference detected between TLRH and RRH group is further strengthened by the great expertise of the surgeon performing laparoscopic surgeries.

RESUMO

Vascular smooth muscle cell (VSMC) senescence is a major driver of neointimal formation. We have demonstrated that circ-Sirt1 derived from the SIRT1 gene suppressed VSMC inflammation and neointimal formation. However, the effect of circ-Sirt1 inhibiting inflammation on VSMC senescence during neointimal hyperplasia remains to be elucidated. Here, we showed that circ-Sirt1 was highly expressed in young and healthy arteries, which was decreased in aged arteries and neointima of humans and mice. Overexpression of circ-Sirt1 delayed Ang II-induced VSMC senescence in vitro and ameliorated neointimal hyperplasia in vivo. Mechanically, circ-Sirt1 inhibited p53 activity at the levels of transcription and post-translation modulation. In detail, circ-Sirt1, on the one hand, interacted with and held p53 to block its nuclear translocation, and on the other hand, promoted SIRT1-mediated p53 deacetylation and inactivation. In conclusion, our data suggest that circ-Sirt1 is a novel p53 repressor in response senescence-inducing stimuli, and targeting circ-Sirt1 may be a promising approach to ameliorating aging-related vascular disease.

RESUMO

Placental site trophoblastic tumor (PSTT) is a rare type of gestational trophoblastic neoplasia (GTN). It is rising from the abnormal proliferation of intermediate trophoblastic cells with occasional multinuclear giant cells, with the potential for local invasion and metastasis. For its untypical and changeable clinical characteristics, the diagnosis and management are still poorly understood. Here we documented a case of PSTT with vaginal lesion as her unique presentation. After surgery and adjuvant chemotherapy, the patient was cured.
