Laparoscopic versus open radical hysterectomy in women with early stage cervical cancer: A systematic review and meta-analysis

This review aimed to evaluate the short term and long-term outcomes of laparoscopic radical hysterectomy (LRH) versus abdominal radical hysterectomy (ARH) for early-stage cervical cancer. A search of PubMed, Medline and Scopus databased from 2000 to 2018 was conducted. Thirty studies were retrieved including 22 retrospective cohort studies and 8 prospective cohort studies. LRH was comparable with ARH in 5-year overall survival (RR = 1.0. 95%CI 0.98–1.03; p = 0.33) and 5-year disease-free survival (RR = 1.02 95%CI 0.97–1.06; p = 0.98). The majority of included studies reported the negative cancer factors which drive adjuvant therapy were similar between two approaches. LRH was associated with lower blood loss and blood transfusion, less postoperative complication, shorter hospital stays and similar intraoperative complication rate compared to ARH. Our data suggested LRH for early-stage cervical cancer was as safe and effective in terms of long-term outcomes, but with lower surgical morbidities.

Neoadjuvant chemotherapy increases the 5-year overall survival of patients with resectable cervical cancer: A systematic review and meta-analysis

Cervical cancer is a global health challenge in women. Neoadjuvant chemotherapy (NACT) is a recent prospect for alternative cervical cancer treatments. This study investigated the efficacy of NACT against resectable cervical cancer based on the medium and long-term survival of patients with the disease. We searched through PubMed, Web of Science, EBSCO and Cochrane Library for relevant reports published by June 2020. The primary outcomes were 3-year and 5-year progression-free survival (PFS) and overall survival (OS) of patients with resectable cervical cancer. Overall, 22 publications encompassing 5627 patients fulfilled the inclusion criteria. We found NACT not to affect both 3-year PFS and OS as well as 5-year PFS of patients with resectable cervical cancer. However, NACT significantly improves the 5-year OS of patients with resectable cervical cancer (HR = 0.83, 95% CI: 0.73–0.94, p = 0.013). Subgroup analysis (RCTs, non-RCTs, NACT + surgery + AT vs. surgery + AT, NACT + surgery + AT vs. CCRT/RT/CRT) further revealed NACT had no significant effect on 5-year PFS of patients with resectable cervical cancer, converse to the 5-year OS subgroup analysis, which validated the beneficial effect of NACT in patients with resectable cervical cancer. In addition, the effect of NACT was most significant in the non-RCTs subgroup (p = 0.012). NACT may improve the long-term prognosis of patients with resectable cervical cancer. However, further large-scale multicenter studies are needed to validate this finding.

Abstract：

Objective To study the relationship between nitric oxide within cervical microenvironment and different HPV types as well as the effect of sodium nitroprusside( SNP), a nitric oxide donor, on the proliferation and apoptosis of cervical cancer cell lines. Methods HPV typing test was assessed from 115 women by using high-risk HPV (HR-HPV) 21 typing test and the release of cervical nitric oxide(NO) was assessed as nitrate, nitrite in cervical fluid. Cervical NO was then compared between women showing different HPV types. Proliferation of Caski and HeLa cervical cells was determined by methyl thiazolyl tetrazolium (MTT) assay, cell apoptosis was detected by flow cytometry after 24 hours treated by different final concentration of SNP (0. 125,0. 25,0. 5,1.0 and 2. 0 mmol/L, respectively). The expressions of HPV E6,E7 gene mRNA and p53 protein were detected by SYBR Green Ⅰ quantitative real-time PCR and western blot. Results ( 1 ) The cervical NO release of women with HR-HPV was higher compared to that in HPV negative women [ (47. 6 ± 1.4) μmol/L vs ( 22. 8 ± 0. 3 ) μmol/L; P ＜ 0. 05 ]; but there was no statistical difference between low-risk HPV (LR-HPV) group [ (24. 1 ± 1.2 ) μmol/L] and control group (P ＞0. 05 ). (2)After 24 hours treated by different final concentration of SNP, the results shown that SNP could inhibited the proliferation and increased apoptosis rate in Caski and HeLa cells, in which the concentration of SNP ≥ 1.0 mmol/L , there were significantly different ( P ＜ 0. 05 ), while when SNP ≥2. 0mmol/L, the proliferation of cells inhibited seriously. Treated by SNP ( 1.0 mmol/L ) 24 hours, the expressions of HPV18 E6, E7 mRNA in HeLa cells were reduced from 27. 362 ±0. 191,22. 962 ±0. 053 to19. 181 ±0. 360, 17. 571 ±0. 010 and the protein expression of p53 increased from 1. 17 ±0. 03 to 0. 23 ±0. 05, there were statistically significant differences between adding SNP group and the control group ( P ＜0. 05); but there were no statistically significant differences in HPV16 E6, E7 mRNA and that of p53 in Caski cells( P ＞ 0. 05 ). Conclusions The presence of HR-HPV is associated with an increased release of NO in the human uterine cervix; NO could inhibit the growth and proliferation and enhance the apoptosis of cervical cancer cells, inhibit the expression of HPV18 E6, E7 mRNA in HeLa cells and activate the expression of p53 protein, the mechanism may be due to higher sensitivity of HeLa cells (cervical adenocarcinoma cell) to SNP. The increasing release of NO may play a role in regulating the elimination of HPV in cervical microenvironment, which is a part of mucous membrane immunity.

腹腔镜下保留盆腔植物神经的解剖性广泛性子宫切除术37例临床分析

Objective To investigate feasibility of laparoscopic anatomical nerve sparing radical hysterectomy (LANSRH) used for locally advanced cervical cancer treatment and evaluate early recovery of bladder function postoperatively. Methods From October 2006 to September 2007, 37 cervical cancer patients with stage Ⅰb1 to Ⅱ a underwent LANSRH(LANSRH group) with pelvic lymphadenectomy matched 25 patients with cervical cancer treated by general laparoscopic radical hysterectomy (LRH,LRH group) with pelvic lymphadenectomy. The data of operating time, blood loss, numbers of lymph node, the length of resected vaginal and paracervix tissue were collected and compared. In the mean time, postoperative recovery of bladder function was evaluated. Results The laparoscopic anatomic nerve-sparing procedure was performed successfully and safely among all patients. (1) There was no remarkable difference in the following clinical parameters between LANSRH and LRH group: median operating time [(175±41) min vs. (178±30) min, P=0.72 ], blood loss [(233±104)ml vs. (218±77) ml, P=0.06], numbers of lymph nodes (13±4 vs. 15±6, P=0.16), resected length of paracervix tissue [(3.6±0.5)cm vs. (3.7±0.6) cm, P=0.43], resected length of vaginal tissue [(3.5±1.0)cm vs. (3.5±0.8) cm, P=0.80]. (2) The mean time of the Foley catheter removed was (10.6±2.7)days(7-17 days)in LANSRH group and (17.2±4.2)days(9-25 days)in LRH group (P=0.02). After Foley catheter removed, 95% (35/37) presented bladder fulfilling sense, 86% (32/37) presented automatic micturition and urination emptying in LANSRH group. However, In LRH group, 88% (22/25) presented bladder fulfilling sense, 76% (19/25) presented automatic micturition and urination emptying. The bladder void function recovery were 68% (25/37) in class 0 and 3% (1/37) in class Ⅱ in LANSRH group, when compared with 40% (10/25) in class 0 and 12% (3/25) in class Ⅱ in LRH group, it reached statistical difference (P<0.05). In the mean time, there was no significant difference in Class Ⅰ bladder void function recovery, which were 24% (9/37) and 48% (12/25). (3) No surgery complications and blood transfusion were observed in LANSRH and LRH group. Postoperative pathology suggested that no tumor cell invasion occurred in paracervix tissue and lymph nodes. During the range of 11 to 19 months follow-up, all patients were alive without tumor recurrence and metastasis. Conclusion LANSRH is safe and feasible surgical management for cervical cancer at early stage and would improve the recovery of bladder voiding function postoperatively by sparing anatomical nerve.

During the range of 11 to 19 months follow-up, all patients were alive without tumor recurrence and metastasis. Conclusion LANSRH is safe and feasible surgical management for cervical cancer at early stage and would improve the recovery of bladder voiding function postoperatively by sparing anatomical nerve.     

腹腔镜下保留盆腔植物神经的解剖性广泛性子宫切除术37例临床分析

Objective To investigate feasibility of laparoscopic anatomical nerve sparing radical hysterectomy (LANSRH) used for locally advanced cervical cancer treatment and evaluate early recovery of bladder function postoperatively. Methods From October 2006 to September 2007, 37 cervical cancer patients with stage Ⅰb1 to Ⅱ a underwent LANSRH(LANSRH group) with pelvic lymphadenectomy matched 25 patients with cervical cancer treated by general laparoscopic radical hysterectomy (LRH,LRH group) with pelvic lymphadenectomy. The data of operating time, blood loss, numbers of lymph node, the length of resected vaginal and paracervix tissue were collected and compared. In the mean time, postoperative recovery of bladder function was evaluated. Results The laparoscopic anatomic nerve-sparing procedure was performed successfully and safely among all patients. (1) There was no remarkable difference in the following clinical parameters between LANSRH and LRH group: median operating time [(175±41) min vs. (178±30) min, P=0.72 ], blood loss [(233±104)ml vs. (218±77) ml, P=0.06], numbers of lymph nodes (13±4 vs. 15±6, P=0.16), resected length of paracervix tissue [(3.6±0.5)cm vs. (3.7±0.6) cm, P=0.43], resected length of vaginal tissue [(3.5±1.0)cm vs. (3.5±0.8) cm, P=0.80]. (2) The mean time of the Foley catheter removed was (10.6±2.7)days(7-17 days)in LANSRH group and (17.2±4.2)days(9-25 days)in LRH group (P=0.02). After Foley catheter removed, 95% (35/37) presented bladder fulfilling sense, 86% (32/37) presented automatic micturition and urination emptying in LANSRH group. However, In LRH group, 88% (22/25) presented bladder fulfilling sense, 76% (19/25) presented automatic micturition and urination emptying. The bladder void function recovery were 68% (25/37) in class 0 and 3% (1/37) in class Ⅱ in LANSRH group, when compared with 40% (10/25) in class 0 and 12% (3/25) in class Ⅱ in LRH group, it reached statistical difference (P<0.05). In the mean time, there was no significant difference in Class Ⅰ bladder void function recovery, which were 24% (9/37) and 48% (12/25). (3) No surgery complications and blood transfusion were observed in LANSRH and LRH group. Postoperative pathology suggested that no tumor cell invasion occurred in paracervix tissue and lymph nodes.
