Objective: To evaluate the effect of postoperative radiotherapy and high-risk pathological factors on the prognosis of early-stage neuroendocrine carcinoma of cervix (NECC). Methods: A single-center retrospective cohort study of early-stage NECC in Peking Union Medical College Hospital from January 2011 to April 2022 were enrolled. The patients were treated with radical hysterectomy±adjuvant treatment. They were divided into postoperative non-radiation group and postoperative radiation group. The possible postoperative recurrence risk factors identified by univariate analysis were assessed using multivariate logistic regression. The Kaplan-Meier method was used to analyze the progression free survival (PFS), overall survival (OS), recurrence rate, and mortality rate. Results: (1) Sixty-two cases were included in the study, including 33 cases in postoperative non-radiation group and 29 cases in postoperative radiation group. (2) The median follow-up time was 37 months (ranged 12-116 months), with 23 cases (37%) experienced recurrences. There were 7 cases (11%) pelvic recurrences and 20 cases (32%) distant recurrences, in which including 4 cases (6%) both pelvic and distant recurrences. Compared with postoperative non-radiation group, the postoperative radiation group had a lower pelvic recurrence rate (18% vs 3%; P=0.074) but without statistic difference, a slightly elevated distant recurrence rate (24% vs 41%; P=0.150) and overall recurrence rate (33% vs 41%; P=0.513) without statistically significances. Univariate analysis showed that lymph-vascular space invasion and the depth of cervical stromal invasion≥1/2 were risk factors for postoperative recurrence (all P<0.05). Multivariate analysis showed lymph-vascular space invasion was an independent predictor for postoperative recurrence (OR=23.03, 95%CI: 3.55-149.39, P=0.001). (3) During the follow-up period, 18 cases (29%, 18/62) died with tumor, with 10 cases (30%, 10/33) in postoperative non-radiation group and 8 cases (28%, 8/29) in postoperative radiation group, without significant difference (P=0.814). The postoperative 3-year and 5-year survival rate was 79.2%, 60.8%. The depth of cervical stromal invasion≥1/2 was more common in postoperative radiation group (27% vs 64%; P=0.011), and postoperative radiation in such patients showed an extended trend in PFS (32.3 vs 53.9 months) and OS (39.4 vs 73.4 months) but without statistic differences (P=0.704, P=0.371). Compared with postoperative non-radiation group, the postoperative radiation did not improve PFS (54.5 vs 37.3 months; P=0.860) and OS (56.2 vs 62.4 months; P=0.550) in patients with lymph-vascular space invasion. Conclusions: Postoperative radiation in early-stage NECC patients has a trend to reduce pelvic recurrence but not appear to decrease distant recurrence and overall recurrence, and has not improved mortality. For patients with the depth of cervical stromal invasion≥1/2, postoperative radiation has a trend of prolonging OS and PFS but without statistic difference. Lymph-vascular space invasion is an independent predictor for postoperative recurrence, but postoperative radiation in such patients does not seem to have any survival benefits.

Cervical cancer is the most common gynecological malignant carcinoma in Chinese women, which seriously threatens women's health. Lymph node metastasis is the most important factor affecting the prognosis and adjuvant treatment of patients with early cervical cancer. Conventional systematic lymphadenectomy has always been a reliable method to detect lymph node metastasis. However, this procedure may affect the quality of life of patients because of high risks of complications. Recently, sentinel lymph node biopsy (SLNB) has been researched aiming to assess the status of pelvic lymph node metastasis intraoperatively, avoid unnecessary lymphadenectomy and achieve the goal of individualized diagnosis and treatment. Exploring efficient tracing methods and pathological ultra-staging is the key to the clinical application of SLNB for cervical cancer, and understanding the latest relevant clinical research progress will help SLNB to be applied in the clinic as soon as possible to benefit patients with cervical cancer.

CT image based organ segmentation is essential for radiotherapy treatment planning, and it is laborious and time consuming to outline the endangered organs and target areas before making radiation treatment plans. This study proposes a fully automated segmentation method based on fusion convolutional neural network to improve the efficiency of physicians in outlining the endangered organs and target areas. The CT images of 170 postoperative cervical cancer stage IB and IIA patients were selected for network training and automatic outlining of bladder, rectum, femoral head and CTV, and the neural network was used to localize easily distinguishable vessels around the target area to achieve more accurate outlining of CTV.

Cervical cancer is a common gynecologic malignancy. Most patients with early-stage cervical cancer received unnecessary systemic pelvic lymphadenectomy, which increased the risk of surgical complications. At present, sentinel lymph node biopsy has been applied in the clinical practice of cervical cancer abroad, however it is still at the starting stage in China in need of application and promotion. The Obstetrics and Gynecology Committee of Chinese Research Hospital Association invited domestic experts in the field of gynecologic oncology to discuss the application value, patient evaluation, technical methods, operation steps, pathological examination and many other key points of sentinel lymph node biopsy based on the current research status, and reached the consensus of clinical application on sentinel lymph node biopsy in cervical cancer to guide the standardized application of the technique in China.

Cervical cancer is the most common gynecologic malignancy. Radical hysterectomy for early-stage cervical cancer could cause damage to pelvic autonomic nerves, leading to postoperative urination, defecation and sexual dysfunction. In order to improve the postoperative quality of life, the international Querleu-Morrow (Q-M) surgical classification system recommends the nerve-sparing radical hysterectomy (type-C1) as the mainstay operation. The Gynecologic Oncology Group affiliated to Chinese Obstetricians and Gynecologists Association has invited a number of domestic specialists and conducted in-depth discussions on key issues such as anatomical basis, surgical indications, techniques, postoperative evaluation for nerve-sparing radical hysterectomy. Finally, the specialists reach a consensus to guide the standardized application of this procedure in China.

BackgroundPelvic exenteration (PE) for primary and recurrent cervical cancer has resulted in favorable survival outcomes, but there are controversies about specific prognosis factors, and up to now, there have been no published reports from China. This study aimed to share our experiences of PE, which were performed in a single institution.

MethodsFrom January 2009 to January 2016, 38 patients with recurrent or persistent cervical cancer were included in the study, and they were followed up until January 2017. Epidemiological and clinicopathological characteristics of patients were compared for survival outcomes in univariate and Cox hazard regression analysis.

ResultsThere were thirty-one and seven patients with recurrent and persistent cervical cancer, respectively. The median age of patients was 45 years (range 29-65 years). Total, anterior, and posterior PE consisted of 52.6%, 28.9%, and 18.4% of cases, respectively. Early and late complications occurred in 21 (55.3%) patients and 15 (39.5%) patients, respectively. Two (5.3%) patients died due to complications related to surgeries within 3 months after PE. The median overall survival (OS) and disease-free survival (DFS) were 28.5 months (range 9-96 months) and 23 months (range 4-96 months), respectively, and 5-year OS and DFS were 48% and 40%, respectively. Cox hazard regression analysis showed that, the margin status of the incision and mesorectal lymph node status were independent risk factors for OS and DFS.

ConclusionIn our patients with recurrent and persistent cervical cancer, the practice of PE might achieve favorable survival outcomes.

OBJECTIVE: This study was conducted using the human papillomavirus (HPV) DNA chip test (HDC), in order to determine whether the HPV genotype is a predictor of residual disease in a subsequent hysterectomy following a loop electrosurgical excision procedure (LEEP) for cervical intraepithelial neoplasia (CIN) 3. METHODS: Between January 2002 and February 2015, a total of 189 patients who underwent a hysterectomy within 6 months of LEEP caused by CIN 3 were included in this study. We analyzed their epidemiological data, pathological parameters, high-risk HPV (HR-HPV) load as measured by the hybrid capture II assay, and HR-HPV genotype as measured by the HDC. A logistic regression model was used to analyze the relationship between covariates and the probability of residual disease in subsequent hysterectomy specimens. RESULTS: Of the 189 patients, 92 (48.7%) had residual disease in the hysterectomy specimen, CIN 2 in seven patients, CIN 3 in 79 patients, IA1 cancer in five patients, and IA2 cancer in one patient. Using multivariate analysis, the results were as follows: cone margin positivity (odds ratio [OR], 2.43; 95% CI, 1.18 to 5.29; p<0.05), HPV viral load > or =220 relative light unit (OR, 2.98; 95% CI, 1.38 to 6.43; p<0.01), positive endocervical cytology (OR, 8.97; 95% CI, 3.81 to 21.13; p<0.001), and HPV-16 or HPV-18 positivity (OR, 9.07; 95% CI, 3.86 to 21.30; p<0.001). CONCLUSION: The HPV-16 or HPV-18 genotype is a reliable predictive factor of residual disease in a subsequent hysterectomy following a LEEP for CIN 3.

OBJECTIVE: We conducted a pooled analysis of published studies to compare the performance of human papillomavirus (HPV) testing and cytology in detecting residual or recurrent diseases after treatment for cervical intraepithelial neoplasia grade 2 or 3 (CIN 2/3). METHODS: Source articles presenting data on posttreatment HPV testing were identified from the National Library of Medicine (PubMed) database. We included 5,319 cases from 33 articles published between 1996 and 2013. RESULTS: The pooled sensitivity of high-risk HPV testing (0.92; 95% confidence interval [CI], 0.90 to 0.94) for detecting posttreatment CIN 2 or worse (CIN 2+) was much higher than that of cytology (0.76; 95% CI, 0.71 to 0.80). Co-testing of HPV testing and cytology maximized the sensitivity (0.93; 95% CI, 0.87 to 0.96), while HPV genotyping (detection of the same genotype between pre- and posttreatments) did not improve the sensitivity (0.89; 95% CI, 0.82 to 0.94) compared with high-risk HPV testing alone. The specificity of high-risk HPV testing (0.83; 95% CI, 0.82 to 0.84) was similar to that of cytology (0.85; 95% CI, 0.84 to 0.87) and HPV genotyping (0.83; 95% CI, 0.81 to 0.85), while co-testing had reduced specificity (0.76; 95% CI, 0.75 to 0.78). For women with positive surgical margins, high-risk HPV testing provided remarkable risk discrimination between test-positives and test-negatives (absolute risk of residual CIN 2+ 74.4% [95% CI, 64.0 to 82.6] vs. 0.8% [95% CI, 0.15 to 4.6]; p<0.001). CONCLUSION: Our findings recommend the addition of high-risk HPV testing, either alone or in conjunction with cytology, to posttreatment surveillance strategies. HPV testing can identify populations at greatest risk of posttreatment CIN 2+ lesions, especially among women with positive section margins.
