Cervical cancer is a serious disease endangering the health of women, which is next only to breast cancer and colon cancer.There are nearly 130 000 new cases of cervical cancer arise in China each year, accounting for 1/5 of the total number of new cases in the world.Epidemiological survey has found that cervical cancer is related to various factors, such as human papilloma virus infection, multiple sexual partners, smoking, premature sexual life, sexually transmitted diseases, economic status and immunosuppression.Cervical cancer is pathologically characterized by cervical dysplasia cervical atypical hyperplasia (mild, moderate, severe) to carcinoma in situ and to infiltrating carcinoma.Female vagina is a relatively anoxic and unique dynamic micro ecological system colonized with a large number of bacteria.And the vaginal microflora is the kernel of maintaining vaginal micro ecological balance.The uterine cervix is directly exposed to the vagina, and is closely related to vaginal microbes.However, there are few reports on the direct relationship between cervical cancer and vaginal microbes.In this review, the roles and significance of vaginal microbial imbalance and common vaginal infections in cervical cancer will be discussed from different angles.

AIM:To study the cisplatin-sensitization effect and mechanism of tripterygium glycosides on cisplatin-resistant human epithelial ovarian cancer cells (SKOV3/DDP).METHODS:The SKOV3/DDP cells in exponential phase of growth were randomly divided into eight groups:blank control group,10 μg/mL DDP group,50 μg/mL GTW group,800 μg/mL GTW group,3 200 μg/mL GTW group,10 μg/mL DDP + 50 μg/mL GTW group,10 μg/mL DDP + 800 μg/mL GTW group and 10 μg/mL DDP + 3 200 μg/mL GTW group.Cell counting kit 8 and flow cytometry and western blot were used to detect the growth inhibiting rate and apoptosis rate and relative expression of GST-π,MDR1,STAT3,p-STAT3 of SKOV3/DDP cells of every group.RESULTS:DDP and GTW produce an additive effect when used concurrently in inhibiting growth of SKOV3/DDP cells.800 μg/mL GTW or 3 200 μg/mL GTW combined with 10 μg/mL DDP can significantly induce apoptosis of SKOV3/DDP cells and downregulate the expression of p-STAT3 (P < 0.05).CONCLUSION:GTW can significantly enhance sensitivity of SKOV3/DDP cells to DDP.The underlying mechanism may be related with down-regulating the expression of p-STAT3 in STAT3 pathway.

Objective:
QL1604 is a highly selective, humanized monoclonal antibody against programmed death protein 1. We assessed the efficacy and safety of QL1604 plus chemotherapy as first-line treatment in patients with advanced cervical cancer.
Methods:
This was a multicenter, open-label, single-arm, phase II study. Patients with advanced cervical cancer and not previously treated with systemic chemotherapy were enrolled to receive QL1604 plus paclitaxel and cisplatin/carboplatin on day 1 of each 21-day cycle for up to 6 cycles, followed by QL1604 maintenance treatment.
Results:
Forty-six patients were enrolled and the median follow-up duration was 16.5 months. An 84.8% of patients had recurrent disease and 13.0% had stage IVB disease. The objective response rate (ORR) per Response Evaluation Criteria in Advanced Solid Tumors (RECIST) v1.1 was 58.7% (27/46). The immune ORR per immune RECIST was 60.9% (28/46).The median duration of response was 9.6 months (95% confidence interval [CI]=5.5–not estimable). The median progression-free survival was 8.1 months (95% CI=5.7–14.0). Fortyfive (97.8%) patients experienced treatment-related adverse events (TRAEs). The most common grade≥3 TRAEs (>30%) were neutrophil count decrease (50.0%), anemia (32.6%), and white blood cell count decrease (30.4%).
Conclusion
QL1604 plus paclitaxel-cisplatin/carboplatin showed promising antitumor activity and manageable safety profile as first-line treatment in patients with advanced cervical cancer. Programmed cell death protein 1 inhibitor plus chemotherapy may be a potential treatment option for the patient population who have contraindications or can’t tolerate bevacizumab, which needs to be further verified in phase III confirmatory study.
