Efecto de COVID-19 en el tratamiento del cáncer cervicouterino: estudio antes/después / Effect of COVID-19 pandemics in treatment of cervical cancer: pre/post study

Resumen Introducción : Hay escasa evidencia sobre el impacto de la pandemia de COVID-19 en el cumplimiento del tratamiento de cáncer cervicouterino. Métodos : Se llevó a cabo un estudio poblacional de cohorte retrospectivo. -antes/después- de las pacientes con cáncer cervicouterino diagnosticadas en estable cimientos públicos de la provincia de Jujuy (n = 140), entre 2017 y 2020. Las pacientes diagnosticadas en 2020 se consideraron expuestas a la pandemia (n = 21). Utili zamos la regresión logística multivariada para analizar la asociación entre pandemia y cumplimiento del tra tamiento de cáncer. Además, se midió la duración del tratamiento en aquellas con indicación de braquiterapia y el tiempo hasta el inicio al tratamiento según estadio. Resultados : Comparadas con las mujeres diagnosti cadas en 2017-2019 el odds ratio de incumplimiento del tratamiento fue de 1.77 (IC95% 0.59-5.81; p = 0.32) para las diagnosticadas durante 2020. Se encontró un mayor riesgo de incumplimiento en pacientes con indicación de braquiterapia (OR 4.14; IC 95%:1.95-9.11; p < 0.001). La mediana de duración del tratamiento para aquellas con indicación de braquiterapia fue de 12.8 y 15.7 sema nas en 2017-2019 y 2020 respectivamente (p = 0.33). La mediana de tiempo hasta el inicio del tratamiento para pacientes con enfermedad en estadio temprano fue de 9 y 5 semanas durante 2017-2019 y 2020 respectivamente (p = 0.06), versus una mediana de 7.2 y 9 semanas en 2017-2019 y 2020 respectivamente (p=0.36) para las pa cientes con enfermedad en estadio IIB+. Conclusiones : El bajo acceso a la braquiterapia fue un factor determinante de incumplimiento de tratamiento de cáncer cervicouterino, independientemente del efecto de la pandemia.

Abstract Introduction : Little evidence exists on the impact of the COVID-19 pandemics on the compliance with cervi cal cancer treatment. Methods : We carried out a population-based, be fore-and-after retrospective cohort study of all cervical cancer patients diagnosed in the Jujuy province public health sector (n=140), Argentina, between 2017 and 2020. Patients diagnosed in 2020 were considered exposed to the COVID-19 pandemic (n=21). We used multivariable logistic regression to assess the relationship between the pandemics and compliance with treatment. We also measured treatment duration for women who were indicated brachytherapy and time to treatment initia tion by stage. Results : Compared with women diagnosed in 2017- 2019 the odds ratio of non-complying with treatment was 1.77 (95%CI 0.59-5.81; p = 0.32) for women diagnosed during 2020. An increased risk of non-compliance was found in patients with prescribed brachytherapy (OR 4.14. 95%CI 1.95-9.11; p < 0.001). Median treatment dura tion for women with prescribed brachytherapy was 12.8 and 15.7 weeks in 2017-2019 vs. 2020 (p = 0.33); median time to treatment initiation for women with early-stage disease was 9 and 5 weeks during 2017-2019 and 2020 respectively (p = 0.06), vs 7.2 and 9 weeks in 2017-2019 and 2020 respectively (p = 0.36) for patients with stages IIB+ disease. Conclusions : Low access to brachytherapy was a major determinant of non-compliance. irrespective of the effect of the pandemics.

HPV-DNA test access based on self-collection of vaginal samples from women living with HIV/AIDS: pilot implementation in Brazil / Autocoleta vaginal por mulheres vivendo com HIV/AIDS para testagem de HPV-DNA: implantação piloto no Brasil

Introduction: Women living with HIV/AIDS have a higher frequency of anogenital neoplasms resulting from human papillomavirus (HPV) infection. The World Health Organization recommends that cervical cancer screening uses molecular tests that amplify viral genetic material, such as HPV-DNA. In addition to collection by health professionals, self-collection of vaginal samples is a useful tool for expanding access to testing. Objective: To describe the results of the pilot study that evaluated the acceptability of self-collection of vaginal samples and the applicability of offering HPV-DNA tests with self-collection of vaginal samples for women living with HIV/AIDS in Brazil. Methods: Descriptive cross-sectional study involving women living with HIV/AIDS treated in eight HIV-specialty healthcare facilities distributed in all regions of the country from May 2021 to May 2022 and a central laboratory. Vaginal self-collection was offered, and participants were interviewed about sociodemographic data and impressions of self-collection. Results: In total, 1,919 women living with HIV/AIDS with an average age of 45 years participated in the study. Some type of HPV was detected in 66% (1,267) of cases. The majority (71.9%) said they preferred self-collection to sample collection by health care professionals. Only 53.8% of participants underwent cytology at the appropriate frequency, as recommended by the protocol. Conclusion: The results may support the implementation of molecular biology tests to detect HPV in women living with HIV/AIDS, including the possibility of vaginal self-collection, promoting increased access to cervical cancer screening.

Prevention and treatment of high-risk human papilloma virus infection from the perspective of "prevention treatment of disease" based on the theory of "circular flow of Qi" / 国际中医中药杂志

The occurrence of cervical cancer in women is closely related to high-risk HPV infection, and timely and effective interruption of high-risk HPV infection is of great significance to prevent the occurrence of cervical cancer. Huang Yuanyou's theory of "circular flow of Qi" emphasizes on the harmonization of the overall Qi flow, which can explain the physiopathology of women. The occurrence of high-risk HPV infection is related to the loss of spleen and earth transportation in the middle Jiao, poor circulation of Qi, and the low resistance of the body to evil, resulting in the malfunctioning of clear and turbid. Based on the theory of "circular flow of Qi" combined with the idea of "prevention treatment of disease", the author proposes to "prevent the disease before it occurs, regulate the middle earth to preserve the correct Qi" and "prevent the disease before it occurs". The principles of prevention and treatment of high-risk HPV infection are "prevent before the disease, regulate the middle earth to preserve the righteousness", "promote and descend to dispel the poisonous evil", and "prevent recurrence after the disease, balance yin and yang and harmonize Qi and blood", in order to provide reference for clinical treatment.

Prognostic value of baseline 18F-FDG PET/CT metabolic parameters in locally advanced cervical cancer after concurrent chemoradiotherapy / 中华核医学与分子影像杂志

Objective:To explore the prognostic value of baseline 18F-FDG PET/CT metabolic parameters in locally advanced cervical cancer (LACC) after concurrent chemoradiotherapy (CCRT). Methods:From September 2015 to October 2021, the clinical data of 180 LACC patients (age: 22-76 years) who underwent 18F-FDG PET/CT before CCRT at Affiliated Cancer Hospital of Shandong First Medical University were analyzed retrospectively. The metabolic tumor volume (MTV), total lesion glycolysis (TLG), SUV max, and SUV mean were computed by using the margin threshold of 42%SUV max. The optimal threshold for predicting progression-free survival (PFS) was obtained by ROC curve analysis. The Kaplan-Meier method was applied for survival analysis, and the log-rank test was applied to compare the survival rate between groups. Multivariate Cox proportional hazard regression was used to analyze progression for PFS. Results:The median follow-up was 19.1 months, and 54 patients (30.0%, 54/180) suffered from disease progression. ROC curve analysis showed that the optimal cut-off value of MTV was 31.145 ml, with the AUC of 0.641. Para-aortic lymph node (PALN) metastasis had the highest AUC value (0.589) among the clinical factors, followed by International Federation of Gynecology and Obstetrics (FIGO) stage (0.581). The 1-year PFS rates of patients with MTV<31.145 ml ( n=88) and MTV≥31.145 ml ( n=92) were 80.68% and 59.78%, respectively ( χ2=13.72, P<0.001). Multivariate Cox analysis demonstrated that pathological type (hazard ratio ( HR)=3.075, 95% CI: 1.370-6.901, P=0.006), FIGO stage ( HR=1.955, 95% CI: 1.031-3.707, P=0.040), PALN metastasis ( HR=2.136, 95% CI: 1.202-3.796, P=0.010) and MTV ( HR=2.449, 95% CI: 1.341-4.471, P=0.004) were the significant predictors for PFS. Conclusions:Pathological type, FIGO stage, PALN metastasis and MTV are independent prognostic risk factors for PFS. MTV as the baseline 18F-FDG PET/CT metabolic parameter, can realize prognostic stratification analysis.

The effect of cuproptosis related gene methylation on the prognosis of cervical cancer / 中华检验医学杂志

To investigate the differences in methylation levels of cuproptosis related genes in cervical cancer and their effects on clinical prognosis.Methods:The methylation data of 310 cervical tissue specimens were acquired from public databases. The UALCAN database was used to analyze the methylation level differences of 12 cuproptosis-related genes and study their level in different stages or grades of cervical cancer. Genes with statistically significant differences were selected for prognosis analysis using the EWAS datahub. Finally, gene-enrichment analysis, pathway analysis, immune infiltration analysis, the mutation rate and tumor mutation burden (TMB) of the genes in cervical cancer were analyzed using the cBioportal database. Two independent samples rank-sum test was used for differences in methylation levels and immune cell infiltration; comparative analyses of overall survival were performed using KM survival curves and Log-rank two-sided tests. TMB analyses were performed using the Wilcoxon Test for statistical analyses; Pearson correlation analysis was used for assessment in GSEA and pathway analyses.Results:The methylationβvalue of Cyclin Dependent Kinase Inhibitor 2A (CDKN2A gene) in the cervical cancer tissues of patients was 0.075 which was significantly higher than the methylationβvalue of 0.049 in normal human tissues ( P=0.008). Dihydrolipoamide S-Acetyltransferase (DLAT gene) methylation with a β value of 0.102 was significantly higher than normal human tissue methylation with a β value of 0.08 ( P=0.002), and the methylation level β value of Lipoyltransferase 1 (LIPT1 gene) in cervical cancer tissues was 0.06,which was significantly lower than normal human tissue methylation value of 0.092 ( P=0.009). Patients with CDKN2A gene methylation levels≥0.199 had an overall survival of 14.75 years, which was lower than that of patients with methylation levels<0.199 (17.56 years) ( P=0.034).The results of gene enrichment analysis indicated that it mainly involves biological processes such as the response to type I interferon and DNA replication. The expression of CDKN2A gene is positively correlated with the number of neutrophils and dendritic cells in the tumor microenvironment( P<0.05), and negatively correlated with the number ofmacrophages( P<0.05). TMB was higher in the group of variants of the CDKN2A gene than in the group of non-variants ( P=0.019). Conclusion:CDKN2A methylation is a potential biomarker for predicting the prognosis of cervical cancer.

Analysis of prognostic factors for clear cell adenocarcinoma of the uterine cervix based on the Surveillance, Epidemiology and End Results database / 肿瘤研究与临床

Objective:To explore the prognostic factors associated with clear cell adenocarcinoma (CCAC) of the uterine cervix based on data in the Surveillance, Epidemiology and End Results (SEER) database.Methods:Clinical data were collected from 431 patients with confirmed CCAC in the SEER database from 1976 to 2017. Survival analysis was performed using the Kaplan-Meier method with log-rank test for comparison between subgroups. Cox proportional hazards model was used to analyze the influencing factors of overall survival (OS).Results:The median age [ M ( Q1, Q3)] of 431 patients was 54 years old (40 years old, 71 years old); there were 333 cases (77.3%) of whit. The median OS time of 431 patients was 93 months (95% CI: 47-148 months), and the 1-, 2-, and 5-year OS rates were 80.1%, 65.8% and 54.2%, respectively. The median OS time was not reached in patients with American Joint Committee on Cancer (AJCC) stage Ⅰ, 83 months (95% CI: 21-144 months) for stage Ⅱ, 32 months (95% CI: 16-47 months) for stage Ⅲ, and 9 months (95% CI: 5-13 months) for stage Ⅳ ( P < 0.001). Median OS time was not reached in patients with SEER stage of localized lesions, 46 months (95% CI: 8-83 months) for regional lesions stage, and 9 months (95% CI: 5-12 months) for distant metastases stage ( P < 0.001). Of the patients with clear AJCC staging and some with unspecified AJCC staging, 118 received surgical treatment alone and 119 received postoperative radiotherapy, the median OS time of the two groups was 443 months (95% CI: 162-723 months) and 102 months (95% CI: 75-129 months), and the difference in OS between the two groups was statistically significant ( P < 0.001). Among the patients with AJCC stage Ⅰ, the 5-year OS rates in surgery-only group and postoperative radiotherapy group were 82.5% and 78.5%, the stage Ⅱ were 80.0% and 52.3%, and the stage Ⅲ were 27.8% and 63.3%, respectively; the differences in OS between different stages were not statistically significant (all P>0.05). Among the patients with SEER localized lesions stage, the 5-year OS rates in surgery-only group and postoperative radiotherapy group were 88.9% and 73.1%, and the difference was statistically significant ( P = 0.012); the regional lesions stage were 45.5% and 60.0%, and the difference was not statistically significant ( P = 0.568). The results of multivariate Cox regression analysis showed that AJCC staging (stage Ⅰ vs. stage Ⅳ, HR = 0.281, 95% CI: 0.178-0.543, P < 0.001; stage Ⅱ vs. stage Ⅳ, HR = 0.347, 95% CI: 0.113-0.439, P < 0.001; stage Ⅲ vs. stage Ⅳ, HR = 0.399, 95% CI: 0.030-0.145, P < 0.001), SEER staging (localized lesions stage vs. distant metastases stage, HR = 0.104, 95% CI: 0.059-0.182, P < 0.001; regional lesions stage vs. distant metastases stage, HR = 0.301, 95% CI: 0.195-0.463, P < 0.001) and whether or not receive surgery (yes vs. no, HR = 0.359, 95% CI: 0.241-0.535, P < 0.001) were independent influencing factors of OS in CCAC patients. Conclusions:AJCC staging, SEER staging and surgery are independent influence factors for OS in patients with CCAC, and postoperative radiotherapy may not provide more survival benefit.

Expression of long non-coding RNA RP13-349O20.2 in cervical cancer tissues and experimental study of its effect on migration, invasion abilities and chemosensitivity of cervical cancer cells / 肿瘤研究与临床

Objective:To explore the expression of long non-coding RNA (lncRNA) RP13-349O20.2 in cervical cancer tissues and its impact on the migration, invasion abilities and chemotherapy sensitivity of cervical cancer cells in vitro and the possible mechanisms.Methods:The GEPIA.CANCER website (the data was updated in June 2023) was used to analyze the relationship between the expression level of RP13-349O20.2 and the overall survival of 253 cervical cancer patients. From January 2020 to August 2022, cancer tissues and paracancerous tissues (>2 cm from the tumor edge) from 40 cervical cancer patients in the Affiliated Tengzhou Central People's Hospital of Xuzhou Medical University were retrospectively collected. Human normal cervical epithelial cells H8 and human cervical cancer cell lines HCC94, C33A, Hela, HCC1106 and SiHa were used for cell experiments in vitro. Real-time fluorescence polymerase chain reaction (qRT-PCR) was used to detect the relative expression of RP13-349O20.2 in cervical cancer tissues, paracancerous tissues and each cell line. The C33A cells with the highest relative expression level of RP13-349O20.2 were transfected with small interfering RNA (siRNA) of RP13-349O20.2 and siRNA of its negative control sequence, and they were si-RP13-349O20.2 group and si-Con group, respectively. The scratch healing assay was used to detect the migration ability of C33A cells in the two groups, the Transwell assay was used to detect the invasion ability of C33A cells, and the CCK-8 method was used to detect the sensitivity of C33A cells to 5-fluorouracil. The absorbance value indicated the cell proliferation ability, the lower the absorbance value, the weaker the proliferation ability, the more sensitive to the drug. Dual-luciferase reporter gene assay was used to verify the targeting relationship between RP13-349O20.2 and miRNA-493-5p (miR-493-5p), miR-493-5p and Nectin-4. qRT-PCR was used to detect the relative expression of miR-493-5p and Nectin-4 mRNA in two groups of C33A cells, and Western blotting was used to detect the expressions of Nectin-4 protein and PI3K-AKT signaling pathway proteins in two groups of cells.Results:Analysis based on data from GEPIA.CANCER website shows that patients with low expression of RP13-349O20.2 had better overall survival than patients with high expression ( P < 0.01). The relative expression levels of RP13-349O20.2 in cervical cancer tissues and paracancerous tissues of 40 patients were 4.04±0.32 and 1.18±0.14, and the difference was statistically significant ( t = 8.29, P < 0.01). Compared with H8 cells, the expressions of RP13-349O20.2 in human cervical cancer cell lines HCC94, C33A, Hela, HCC1106 and SiHa were higher (all P < 0.01). The relative expression levels of RP13-349O20.2 in C33A cells in the si-Con group and si-RP13-349O20.2 group were 7.30±0.30 and 1.01±0.27, and the difference was statistically significant ( t = 15.62, P < 0.01). The scratch healing rates of C33A cells in the si-Con group and si-RP13-349O20.2 group were (32±9)% and (75±6)% ( t = 3.97, P < 0.01), and the numbers of invasive cells were (106±12) cells and (36±8) cells ( t = 4.79, P < 0.01). After the action of 5, 10, 20, 40 and 80 μmol/L 5-fluorouracil for 24 h, the absorbance value of C33A cells in the si-RP13-349O20.2 group was lower than that in the si-Con group. Dual-luciferase reporter gene assay confirmed that there was a targeting relationship between P13-349O20.2 and miR-493-5p ( P < 0.01), and there was a targeting relationship between miR-493-5p and Nectin-4 ( P < 0.01) . The relative expression levels of miR-493-5p in C33A cells in the si-Con group and si-RP13-349O20.2 group was 1.02±0.13 and 5.48±0.85 ( t = 5.21, P < 0.01). The relative expression levels of Nectin-4 mRNA were 5.65±0.33 and 0.99±0.34 ( t = 9.87, P < 0.01). The expression of Nectin-4 protein in C33A cells in the si-RP13-349O20.2 group was lower than that in the si-Con group ( t = 9.21, P = 0.001), and the expressions of PI3K-AKT signaling pathway proteins p-STAT3, p-PI3K, p-AKT and p-mTOR were lower than those in the si-Con group (all P < 0.01). Conclusions:The level of RP13-349O20.2 in cervical cancer tissues is high, and its high expression may indicate the poor prognosis of patients. Interfering with the expression of RP13-349O20.2 in vitro can inhibit the migration and invasion abilities of cervical cancer cells and promote the sensitivity of cervical cancer cells to 5-fluorouracil. The mechanism may be related to the miR-493-5p/Nectin-4 signaling pathway and the PI3K-AKT signaling pathway.

Objective:To analyze and summarize the oncological outcomes after laparoscopic radical trachelectomy (LRT) for early stage cervical cancer.Methods:The clinical data and follow-up results of 148 patients with early stage cervical cancer who underwent LRT in Renji Hospital, School of Medicine, Shanghai Jiao Tong University from July 2014 to June 2023 were collected, while tumor outcomes and postoperative pregnancy were analyzed retrospectively.Results:(1) General situation: the median age of 148 patients with LRT was 33 years (range: 19-42 years). Pathological type: 111 cases of squamous cell carcinoma, 36 cases of adenocarcinoma, 1 case of adenosquamous carcinoma. International Federation of Gynecology and Obstetrics (2018) stage: 17 cases of stage Ⅰa1 with lympho-vascular space invasion, 25 cases of stage Ⅰa2, 102 cases of stage Ⅰb1, and 4 cases of stage Ⅰb2. (2) Tumor outcomes: 148 patients were followed up regularly after LRT, and the median follow-up time was 59 months (range: 2-104 months). During the follow-up period, 5 cases of tumor recurred (including 1 death), and the median recurrence time was 10 months (range: 4-33 months). Among them, there were 3 cases of pelvic metastasis, 1 case of distant metastasis, and 1 case of both pelvic and distant metastasis. Both 3-year and 5-year disease-free survival rates of 148 patients were 94.5%, and the 5-year overall survival rate was 98.9%. (3) Postoperative pregnancy: among 148 patients with LRT, 67 patients had pregnancy requirements, followed up for 1 year, and 20 of them were pregnant, with a pregnancy rate of 29.9% (20/67). Among the 20 pregnant patients, 2 cases early abortion, 1 case mid-term abortion, and 17 cases gave birth (including 4 cases of premature birth and 13 cases of full-term birth).Conclusion:Under the condition of strict control of surgical indications, guaranteed surgical scope and tumor-free operation, LRT in patients with early cervical cancer has a good outcome.

Value of surgery combined chemotherapy and radiation therapy in locally advanced neuroendocrine carcinoma of the cervix: a single-center retrospective cohort study / 中华妇产科杂志

Objective:To evaluate the surgery combined chemotherapy and radiation in locally advanced neuroendocrine carcinoma of the cervix (NECC) .Methods:This is a single-center retrospective cohort study. Locally advanced NECC patients admitted to Peking Union Medical College Hospital, Chinese Acadmy of Medical Sciences from January 2011 to April 2022 were enrolled. They were divided into concurrent chemoradiotherapy group, and surgery combined with chemotherapy and radiation group. The Kaplan-Meier method was used to analyze the progression free survival (PFS), overall survival (OS), recurrence rate, and mortality rate.Results:(1) Forty-six cases were included, 22 in concurrent chemoradiotherapy group, 24 in surgery combined chemotherapy and radiation group. With 16 patients (35%, 16/46) received neoadjuvant chemotherapy (NACT), the NACT effective rate was 15/16. (2) The median follow-up time was 27.5 months (range: 10-106 months), with 26 (57%, 26/46) experienced recurrences. There were 4 (9%, 4/46) pelvic recurrences and 25 (54%, 25/46) distant recurrences, and 3 (7%, 3/46) both pelvic and distant recurrences. Compared with concurrent chemoradiotherapy group, surgery combined chemotherapy and radiation group had lower pelvic recurrence rate [14% (3/22) vs 4% (1/24); χ2=1.296, P=0.255] but without statistic difference. Both groups had similar distant recurrence rate [55% (12/22) vs 54% (13/24); χ2=0.001, P=0.979] and overall recurrence rate [59% (13/22) vs 54% (13/24); χ2=0.113, P=0.736]. (3) During the follow-up period, 22 cases (48%, 22/46) died, with 11 cases (50%, 11/22) in concurrent chemoradiotherapy group and 11 cases (46%, 11/24) in surgery combined chemotherapy and radiation group, without significant difference ( χ2=0.080, P=0.777). The postoperative 3-year and 5-year OS rates were 62.3% and 36.9%. Compared with concurrent chemoradiotherapy group, the patients in surgery combined chemotherapy and radiation group showed an extended trend in PFS (17.0 vs 32.0 months) and OS (37.0 vs 50.0 months) but without statistic differences ( P=0.287, P=0.125). Both groups had similar 3-year OS rate (54.2% vs 69.9%; P=0.138) and 5-year OS rate (36.1% vs 38.8%; P=0.217). Conclusions:Our study supports the multi-modality treatment strategy (including surgery, chemotherapy and radiation) as an important component in the treatment of locally advanced NECC. The combination of surgery, chemotherapy and radiation seems to have advantages in the treatment of locally advanced NECC, but needs to be confirmed by further multicenter studies.

Relationship between serum miR-501 and miR-195 levels and sensitivity to concurrent chemoradiotherapy in patients with locally advanced cervical cancer / 中华放射肿瘤学杂志

Objective:To investigate the relationship between serum miR-501 and miR-195 levels and sensitivity to concurrent chemoradiotherapy in patients with locally advanced cervical cancer (LACC).Methods:Clinical data of 96 patients with LACC admitted to Nanyang Central Hospital from January 2020 to June 2022 were retrospectively analyzed and compared with those of 96 healthy subjects during physical examination in our hospital during the same period to compare the differences of serum miR-501 and miR-195 levels. Tumor status was reviewed at 6 months after concurrent chemoradiotherapy. Patients were divided into the sensitive and resistant groups according to the evaluation criteria of solid tumor efficacy. The relationship between serum miR-501 and miR-195 levels and the sensitivity to concurrent chemoradiotherapy in LACC patients was analyzed by univariate and multivariate analyses. The receiver operating characteristic (ROC) curve was also drawn to predict differential efficacy of concurrent chemoradiotherapy sensitivity in LACC patients. Multivariate analysis was conducted by binary logistic regression analysis. P<0.05 indicated statistically significant differences. Results:In LACC patients, serum miR-501 level was significantly higher, whereas serum miR-195 level was significantly lower than those in physical examination subjects (both P<0.05). Univariate analysis showed that serum miR-501 level at admission in the resistant group was significantly higher, whereas serum miR-195 level was significantly lower than those in the sensitive group (both P<0.05). Multivariate analysis showed that serum miR-501 and miR-195 levels were significantly correlated with the sensitivity to concurrent chemoradiotherapy in LACC patients. The area under the ROC curve (AUC) was 0.736 and 0.913, respectively. Conclusions:The higher the serum miR-501 level and the lower the serum miR-195 level before treatment, the higher the probability of resistance to concurrent chemoradiotherapy in LACC patients. Serum miR-501 and miR-195 levels of LACC patients before treatment have certain predictive value for the sensitivity to concurrent chemoradiotherapy.

Tumor volume affects the short-term efficacy of cervical cancer and brachytherapy / 中华放射肿瘤学杂志

Objective:To evaluate the effect of tumor volume on the radiation dose and efficacy of locally advanced cervical cancer patients undergoing radical radiotherapy and chemotherapy.Methods:Clinical data of 126 patients who were diagnosed with cervical cancer (stage ⅡB-ⅣA) and underwent radical concurrent chemoradiotherapy in Guangxi Medical University Cancer Hospital from November 2019 to November 2022 were retrospectively analyzed. The cut-off values of tumor volume before (pre-TV) and after (post-TV) external radiotherapy and tumor volume reduction rate (TVRR) were calculated by Jamovi software. The effects of pre-TV, post-TV and TVRR on short-term efficacy, progression-free survival (PFS), brachytherapy (BT) mode , high-risk clinical target volume (HR-CTV) and organs at risk (OAR) dose were investigated by univariate and multivariate analyses.Results:Pre-TV≥67.03 cm 3 and post-TV≥14.88 cm 3 were poor prognostic factors for 6-month PFS and objective response rate (ORR) (both P<0.05), and post-TV was an independent prognostic factor. In the TVRR≥73.0% and <73.0% groups, no statistical differences were observed in the 6-month PFS and ORR. In the pre-TV≥67.03 cm 3 group, the cases number of intracavitary brachytherapy (ICBT) and intracavitary / interstitial brachytherapy (IC/IS-BT) was 36 (50.0%), while in the pre-TV<67.03 cm 3 group, the cases number of ICBT and IC/IS-BT was 41 (76%) and 13 (24%), respectively ( P=0.003). In the post-TV≥14.88 cm3 group, the cases number of ICBT and IC/IS-BT was 28 (47%) and 32 (53%), while 49 (72%) and 17 (26%) in the post-TV<14.88 cm3 group, respectively ( P=0.002). The dose of HR-CTV D 90% in the TVRR≥73.0% group was significantly higher than that in the TVRR<73.0% group ( P=0.014), but there was no significant difference in the dose of bladder D 2 cm3, rectal D 2 cm3 and small intestine D 2 cm3 (all P>0.05). The dose of HR-CTV D 90% in the post-TV<14.88 cm 3 group was significantly higher than that in post-TV≥14.88 cm 3 group ( P<0.001), and the dose of bladder D 2 cm3 in the post-TV≥14.88 cm 3 group was higher than that in the post-TV<14.88 cm 3 group ( P<0.05). There was no significant difference in the dose of rectal D 2 cm3 and small intestinal D 2 cm3 between two groups (both P>0.05). The number of concurrent chemotherapy (≥4 times vs.<4 times) had no statistical difference for 6-month PFS and TVRR. Conclusions:Pre-TV and post-TV are the influencing factors of short-term efficacy and BT mode selection for locally advanced cervical cancer. Post-TV is an independent prognostic factor and also indirectly affects the dose of HR-CTV D 90% and bladder D 2 cm3 Increasing the number of concurrent chemotherapy (≥4 times) does not improve TVRR and short-term efficacy.

Design and clinical application of intracavitary-interstitial brachytherapy applicator template in locally advanced cervical cancer / 中华放射肿瘤学杂志

Objective:To design and evaluate the application value of intracavitary-interstitial brachytherapy (IC-ISBT) applicator template for locally advanced cervical cancer.Methods:MRI data of 100 patients with ⅡB-ⅣA stage cervical cancer (International Federation of Gynecology and Obstetrics 2018 staging system) before and after external beam radiation therapy (EBRT) admitted to Sun Yat-sen University Cancer Center from March 2019 to September 2020 were collected. The range of primary cervical lesions was retrospectively analyzed and compared. Based on the residual mass of patients, the corresponding high-risk clinical target volume (HR-CTV) was delineated, and the IC-ISBT applicator template was designed and initially applied to cervical cancer patients. Dosimetry analysis and efficacy evaluation were compared between the applicator template-guided ( n=37) and free-hand implantation groups ( n=63). Chi-square test or Fisher exact test was performed for categorical variables, and t-test or U-test for continuous variables. Results:The median distance between the residual tumor margin (clockwise 3, 6, 9, 12 o'clock) and the center of 100 patients with ⅡB-ⅣA stage cervical cancer after EBRT was 16.5, 14.0, 17.0 and 13.0 mm, respectively. The corresponding HR-CTV was superimposed to reconstruct the three-dimensional diagram, and the cylindrical IC-ISBT applicator template with mushroom-like head was designed and manufactured: the longest and shortest diameter of the head was 35 and 20 mm, respectively; the central channel was adapted to the uterine tube, the C1-C12 channels was arranged in inner circle, and the peripheral B1-B5 and A1-A4 pin channels were expanded bilaterally. In terms of dose coverage, there was no significant difference between the HR-CTV D 90% [(635.12±22.65) vs. (635.80±25.84) cGy], bladder D 2 cm3 [(473.79±44.78) vs. (463.55±66.43) cGy)], rectum D 2 cm3 [(396.99±73.54) vs. (408.00±73.94) cGy] and sigmoid colon D 2 cm3 [(293.07±152.72) vs. (311.31±135.77) cGy] between the template-guided and free-hand implantation groups (all P>0.05), but the HR-CTV D 98% was significantly higher [(544.78±32.07) vs. (536.78±32.04) cGy, P=0.007] and the rectum D 1 cm3 and D 0.1 cm3 were significantly lower [(438.62±69.65) vs. (453.97±67.89) cGy, P=0.016; (519.46±70.67) vs. (543.82±81.24) cGy, P=0.001] in the template-guided implantation group. In addition, there was no significant difference in the complete response rate between two groups (86% vs. 83%, P>0.05). Conclusions:This IC-ISBT applicator template is reasonably designed, and the therapeutic efficacy of the template-guided implantation is equivalent to that of free-hand implantation. The dose coverage of the target area meets the clinical demand with a better protection of the organs at risk. The applicator template has the potential to be widely used as a conventional template in clinical practice as the applicator-guided implantation is convenient to operate and repeat.

Research on the robustness of Ethos cervical cancer online fully automatic generation of adaptive plans / 中华放射肿瘤学杂志

Objective:To evaluate the robustness of fully automated adaptive planning for Ethos online adaptive radiotherapy (ART) based on the intelligent optimization engine (IOE).Methods:Clinical data of 11 stage ⅠB cervical cancer patients admitted to Peking Union Medical College Hospital between June 2021 and June 2022 were retrospectively analyzed. Original planning images and iterative cone-beam computed tomography (iCBCT) images of each radiotherapy treatment were acquired, and all patient data were imported into the Ethos simulator. IOE-based 9-field automatic plan generation was performed for 11 patients using Ethos, and the generated plans were sent to online adaptive radiotherapy simulation to obtain each online adaptive radiotherapy plan (273 fractions in total) and complete the simulated treatment. For comparison, manual plan design was performed based on the images and contoured structures used for online adaptive radiotherapy planning, and the manually plans created with evenly divided 9 fields. Dosimetric parameters, plan complexity parameters, and Mobius quality assurance (QA) pass rates were collected to compare and evaluate the robustness of the online adaptive radiotherapy plan in terms of organs at risk (OAR), target volume dosimetric parameters, and plan complexity by using paired t-test or rank sum test. Results:The online adaptive plan of cervical cancer had comparable planning target volume (PTV) coverage compared to the manual plan. For the clinical target volume (CTV) D 99%, online adaptive plan was significantly higher than the manual plan [(45.93±0.36) vs. (45.32±0.31) Gy, P<0.001]. For hot dose area, the maximum point dose (PTV D max) of adaptive plan was significantly higher than the manual plan [(49.89±1.25) vs. (48.48±0.77) Gy, P<0.001], but the PTV D 1% of adaptive plan was significantly lower than the manual plan [(47.22±0.29) vs. (47.59±0.48) Gy, P<0.001]. There was no statistical difference in the conformal index ( P=0.967). And there was significant difference in the homogeneity index, with same medians and less dispersion in adaptive plan ( P<0.001). For OAR dose, bladder D mean, rectal V 40 Gy, small intestine D mean of adaptive plan was slightly higher than that of the manual plan; the rectal D mean, small intestine D 2 cm3 of the adaptive plan was slightly lower than that of manual plan; dosimetric parameters of right and left femoral heads, spinal cord and bone marrow of the adaptive plan were better than those of manual plan. The adaptive plan had more monitor units (MU) than the manual plan, but the complexity of the adaptive plan was significantly lower than that of the manual plan (0.135±0.012 vs. 0.151±0.015, P<0.001). For Mobius γ pass rate (5%/3 mm), both adaptive and manual plans met clinical requirements. Conclusion:Ethos cervical cancer online adaptive plan, which is based on the IOE engine, demonstrates good robustness and ensures the quality of online adaptive plans generated for each treatment fraction.

Pattern and prognosis of recurrence and metastasis of cervical cancer after radical chemoradiotherapy / 中华放射肿瘤学杂志

Objective:To explore the recurrence pattern and prognosis of cervical cancer after radical chemoradiotherapy.Methods:Clinical and follow-up data of 1 359 patients with stage Ⅰ-ⅣA (International Federation of Gynecology and Obstetrics 2009 staging) who received radical radiotherapy in Zhejiang Cancer Hospital from August 2011 to December 2017 were retrospectively analyzed. The survival and prognostic factors of 249 patients with recurrence / metastasis with detailed data were analyzed. The primary endpoint was post-recurrence / metastasis survival time. Kaplan-Meier method was used to calculate the survival rate, log-rank test was used for single factor analysis, and Cox model was used for multi-factor analysis.Results:The distant metastasis rate of 249 patients was 77.5%, and the local recurrence rate was 36.9%. According to the location of metastasis and recurrence, 56 cases with recurrence in the field of radiotherapy alone were assigned into group A, 157 cases with recurrence outside the radiation field alone were allocated into group B (56 cases with lymph node recurrence in group B1, 78 cases with blood metastasis in group B2, and 23 cases with lymph node and blood metastasis simultaneously in group B3), and 36 cases with combined recurrence and metastasis in and out of the field of radiotherapy were assigned into group C. The median survival time of patients in groups A, B1, B2, B3 and C was 13, 24, 13, 11 and 9 months, respectively (all P<0.001). According to the interval from initial diagnosis to recurrence / metastasis, 110 cases were classified in ≤1 year group, 74 cases in >1-2 years group, and 65 cases in >2 years group. The median survival time of patients in the three groups was 11, 14, and 22 months, respectively (all P<0.001). According to the management of recurrence / metastasis, 138 cases received palliative treatment, 15 cases received local treatment, 45 cases received systemic treatment, and 51 cases received combined treatment. The median survival time of patients among four groups was 9, 37, 20 and 32 months, respectively (all P<0.001). The results of multi-factor analysis showed that age, recurrence / metastatic site, retreatment methods, time interval between initial treatment and recurrence /metastasis were the independent prognostic factors affecting the survival (all P<0.05). Conclusions:Distant metastasis is the main failure pattern after radical radiotherapy. Patients with metastasis out of irradiated regions, especially those with only lymph node metastasis, have good prognosis. Active retreatment and time interval between initial diagnosis and recurrence / metastasis are important prognostic factors.

Research advances in the treatment of cervical cancer with liver metastasis / 临床肝胆病杂志

Though liver metastasis of cervical cancer has a relatively low incidence rate， it is often accompanied by metastasis in other sites and thus has a poor prognosis. For the patients with liver metastasis of cervical cancer， it is necessary to formulate individualized treatment regimens based on various factors such as general status， lesion distribution， initial treatment modality， and life expectancy， so as to prolong the overall survival of patients and improve their quality of life. With reference to related studies in China and globally， this article reviews the clinical features， treatment， and prognosis of cervical cancer with liver metastasis.
