Chen YH, Wu JX, Yang SF, Wu YC, Hsiao YH. Molecular Mechanisms Underlying the Anticancer Properties of Pitavastatin against Cervical Cancer Cells. Int J Mol Sci 2024; 25:7915. [PMID: 39063157 PMCID: PMC11277542 DOI: 10.3390/ijms25147915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2024] [Revised: 06/27/2024] [Accepted: 07/10/2024] [Indexed: 07/28/2024] Open
Abstract
Cervical cancer ranks as the fourth most prevalent form of cancer and is a significant contributor to female mortality on a global scale. Pitavastatin is an anti-hyperlipidemic medication and has been demonstrated to exert anticancer and anti-inflammatory effects. Thus, the purpose of this study was to evaluate the anticancer effect of pitavastatin on cervical cancer and the underlying molecular mechanisms involved. The results showed that pitavastatin significantly inhibited cell viability by targeting cell-cycle arrest and apoptosis in Ca Ski, HeLa and C-33 A cells. Pitavastatin caused sub-G1- and G0/G1-phase arrest in Ca Ski and HeLa cells and sub-G1- and G2/M-phase arrest in C-33 A cells. Moreover, pitavastatin induced apoptosis via the activation of poly-ADP-ribose polymerase (PARP), Bax and cleaved caspase 3; inactivated the expression of Bcl-2; and increased mitochondrial membrane depolarization. Furthermore, pitavastatin induced apoptosis and slowed the migration of all three cervical cell lines, mediated by the PI3K/AKT and MAPK (JNK, p38 and ERK1/2) pathways. Pitavastatin markedly inhibited tumor growth in vivo in a cancer cell-originated xenograft mouse model. Overall, our results identified pitavastatin as an anticancer agent for cervical cancer, which might be expanded to clinical use in the future.

Locally Advanced Cervical Cancer: Neoadjuvant Treatment versus Standard Radio-Chemotherapy-An Updated Meta-Analysis. Cancers (Basel) 2024; 16:2542. [PMID: 39061182 PMCID: PMC11275180 DOI: 10.3390/cancers16142542] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2024] [Revised: 07/10/2024] [Accepted: 07/12/2024] [Indexed: 07/28/2024] Open
Abstract
BACKGROUND The treatment of choice for patients with locally advanced cervical cancer (LACC) is definitive concurrent radio chemotherapy which consists of external beam radiotherapy (EBRT) and concurrent platinum-based chemotherapy (CCRT), with the possible addition of brachytherapy (BT). However, the benefits of adjuvant surgery after neoadjuvant treatments remain a debated issue and a still open question in the literature. This meta-analysis aims to provide an updated view on the controversial topic, focusing on comparing surgery after any adjuvant treatment and standard treatment. METHODS Following the recommendations in the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement, the PubMed and Embase databases were systematically searched in April 2023 for early publications. No limitations on the country were applied. Only English articles were considered. The comparative studies containing data about disease-free survival (DFS) and/or overall survival (OS) were included in the meta-analysis. RESULTS The CCRT + surgery group showed a significantly better DFS than CCRT (RR 0.69 [95% CI 0.58-0.81] p < 0.01) and a better OS (RR 0.70 [95% CI 0.55-0.89] p < 0.01). Nine studies comparing neoadjuvant chemotherapy (NACT) plus surgery and CCRT were also enrolled. The NACT + surgery group showed a significantly better DFS than CCRT (RR 0.66 [95% CI 0.45-0.97] p < 0.01) and a better OS (RR 0.56 [95% CI 0.38-0.83] p < 0.01). In the sub-analysis of three randomized control trials, the surgery group documented a non-significantly better DFS and OS than CCRT (OR 1.10 [95% CI 0.67-1.80] p = 0.72; I2 = 69% p = 0.72; OR 1.09 [95% CI 0.63-1.91] p = 0.75; I2 = 13% p = 0.32). CONCLUSION The results provide updated findings about the efficacy of neoadjuvant treatments, indicating significantly improved DFS and OS in patients undergoing hysterectomy after CCRT or NACT compared with patients undergoing standard treatments.

J Obstet Gynaecol Res 2024.

Abstract
Radiotherapy is an effective treatment method for cervical cancer and is typically administered as external beam radiotherapy followed by intracavitary brachytherapy. In Japan, center shielding is used in external beam radiotherapy to shorten treatment time and reduce the doses delivered to the rectum or bladder. However, it has several challenges, such as uncertainties in calculating the cumulative dose. Recently, external beam radiotherapy has been increasingly performed with intensity-modulated radiotherapy, which reduces doses to the rectum or bladder without center shielding. In highly conformal radiotherapy, uncertainties in treatment delivery, such as inter-fractional anatomical structure movements, affect treatment outcomes; therefore, image-guided radiotherapy is essential for appropriate and safe performance. Regarding intracavitary brachytherapy, the use of magnetic resonance imaging-based image-guided adaptive brachytherapy is becoming increasingly widespread because it allows dose escalation to the tumor and accurately evaluates the dose delivered to the surrounding normal organs. According to current evidence, a minimal dose of D90% of the high-risk clinical target volume is significantly relevant to local control. Further improvements in target coverage have been achieved with combined interstitial and intracavity brachytherapy for massive tumors with extensive parametrical involvement. Introducing artificial intelligence will enable faster and more accurate generation of brachytherapy plans. Charged-particle therapies have biological and dosimetric advantages, and current evidence has proven their effectiveness and safety in cervical cancer treatment. Recently, radiotherapy-related technologies have advanced dramatically. This review provides an overview of technological innovations and future perspectives in radiotherapy for cervical cancer.

Reirradiation for recurrent gynecologic cancer using high-dose-rate brachytherapy in Japan: A multicenter survey on practice patterns and outcomes. Radiother Oncol 2024; 195:110269. [PMID: 38583719 DOI: 10.1016/j.radonc.2024.110269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 04/02/2024] [Accepted: 04/02/2024] [Indexed: 04/09/2024]
Abstract
BACKGROUND AND PURPOSE The aim of the study is to examine the present status of reirradiation with high-dose-rate (HDR) brachytherapy for recurrent gynecologic cancer in Japan and to determine the role of this therapy in clinical practice. MATERIALS AND METHODS A retrospective multicenter chart review was performed for reirradiation for gynecologic cancer using HDR brachytherapy. Each center provided information on patient characteristics, treatment outcomes, and complications. RESULTS The study included 165 patients treated at 9 facilities from 2000 to 2018. The analysis of outcomes included 142 patients treated with curative intent. The median follow-up time for survivors was 30 months (range 1-130 months). The 3-year overall survival (OS), progression-free survival (PFS), and local control (LC) rates were 53 % (95 %CI: 42-63 %), 44 % (35-53 %), and 61 % (50-70 %) for cervical cancer; 100 % (NA), 64 % (30-85 %), and 70 % (32-89 %) for endometrial cancer; and 54 % (13-83 %), 38 % (6-72 %), and 43 % (6-78 %) for vulvar and vaginal cancer, respectively. In multivariate analysis, interval to reirradiation (<1 year) was a significant risk factor for OS, PFS and LC; Gross Tumor Volume (≥25 cm3) was a significant risk factor for OS. Toxicities were analyzed in all enrolled patients (n = 165). Grade ≥ 3 late toxicities occurred in 49 patients (30 %). A higher cumulative EQD2 (α/β = 3) was significantly associated with severe complications. CONCLUSION Reirradiation with HDR brachytherapy for recurrent gynecologic cancer is effective, especially in cases with a long interval before reirradiation.

Abstract
INTRODUCTION Cervical cancer is a global public health concern. Despite ESGO recommendations and FIGO classification changes, management of locally advanced cervical cancer (LACC) remains debated in France. Our study aimed to review LACC treatment practices and assess adherence to ESGO recommendations among different practitioners. METHODS From February 2021 to August 2022, we conducted a survey among gynecologic oncology surgeons, radiation oncologists, and medical oncologists practicing in France and managing LACC (FIGO stages IB3-IVA) according to the 2018 FIGO classification. We analyzed responses against the 2018 ESGO recommendations as a "gold standard." RESULTS Among 115 respondents (56% radiation oncologists, 30% surgeons, 13% medical oncologists), 48.6% of gynecologic surgeons didn't perform para-aortic lymphadenectomy (PAL) with significant radiologic pelvic involvement. PAL, when indicated by PET-CT, was more common in university hospitals (66.7% of surgeons). Surgeons in university hospitals also followed ESGO recommendations more closely. Overall, compliance with all ESGO recommendations was low: 5.7% of surgeons, 21.5% of radiation oncologists, and 60% of medical oncologists. Prophylactic para-aortic irradiation, per ESGO, was more frequent in comprehensive cancer centers (52% of radiation oncologists). CONCLUSION Adherence to ESGO recommendations for LACC treatment appears low in France, particularly in surgery, with limited PAL in cases of lymph node negativity on PET-CT. However, these recommendations are more often followed by surgeons in university hospitals and radiation oncologists in cancer centers. Adherence to these recommendations may impact patient survival and warrants evaluation of care quality, justifying the organization of LACC management in expert centers.

Abstract
Cervical cancer (CC) is a common gynecological malignancy, and improving cisplatin sensitivity has become a hot topic in CC chemotherapy research. Polyphyllin I (PPI), a potent bioactive compound found in Rhizoma Paridis, known for its anticancer properties, remains underexplored in CC resistance. In this study, we evaluated PPI's impact on cisplatin-resistant CC cells and elucidated its underlying mechanism. Our findings reveal that PPI enhances the sensitivity of cisplatin-resistant CC cells to the drug, promotes apoptosis, and inhibits cell migration. Mechanistically, PPI was found to regulate p53 expression and its target genes, and suppressing p53 expression reverses PPI's sensitizing effect in drug-resistant CC cells. In conclusion, PPI showed promise in sensitizing cisplatin-resistant human CC cells to cisplatin treatment, suggesting that it could serve as a potent adjunct therapy for cervical cancer, particularly for cases that have developed resistance to cisplatin, thereby providing a promising basis for further clinical investigation into PPI for enhancing the efficacy of existing chemotherapy regimens in resistant cervical cancer.

Abstract
PURPOSE Shared decision making (SDM) is an approach where clinicians and patients make decisions together using the best available evidence. Although much studied, recognized to be ethically imperative, and recommended in international health policies, it remains poorly implemented. In the Philippines, there are limited studies on patient decision making preferences and SDM. Practical guidance on the implementation of SDM or use of patient decision aids (PtDAs) is often not detailed in existing national clinical practice guidelines in oncology. METHODS We performed a systematic search of Philippine literature on SDM in oncology and an iterative review of international literature on the philosophy and methods of SDM, the utility and effectiveness of PtDAs, and the facilitators and barriers to implementation or usage. We contextualized our review to the cervical cancer management and health service delivery in the Philippines. RESULTS Local literature is limited to five scientific publications and two registered studies. International literature encompasses patient decisional preferences, the role of PtDAs and the standards for their development and evaluation, their effectiveness, and barriers and facilitators to their use in cancer-related decision making. We discussed the implications on the management of cervical cancer in the Philippines, challenges in health service delivery and standards, and SDM research. CONCLUSION Local SDM research is limited. Our preliminary experience in a multicenter clinical trial in Manila on PtDA use in the framework of SDM in cervical cancer suggest good patient and clinician acceptability. Challenges to implementation such as unfavorable financial situations, urgency of clinical decisions, low patient or caregiver educational attainment, and poor integration of multidisciplinary and SDM in organizational workflows will be important when implementing SDM in different settings.

Abstract
Squamous cervical carcinoma (SCC) requires particular attention in diagnostic and clinical management. New diagnostic tools, such as (positron emission tomography-magnetic resonance imaging) PET-MRI, consent to ameliorate clinical staging accuracy. The availability of new technologies in radiation therapy permits to deliver higher dose lowering toxicities. In this clinical scenario, new surgical concepts could aid in general management. Lastly, new targeted therapies and immunotherapy will have more room in this setting. The aim of this narrative review is to focus both on clinical management and new therapies in the precision radiotherapy era.

Utilization and Impact of a Radiation Nursing Clinic to Address Acute Care Needs for Patients with Gynecologic Cancers. Curr Oncol 2024; 31:1645-1655. [PMID: 38534958 PMCID: PMC10969712 DOI: 10.3390/curroncol31030125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Revised: 03/14/2024] [Accepted: 03/19/2024] [Indexed: 05/26/2024] Open
Abstract
BACKGROUND The risk factors for acute care utilization in gynecologic oncology patients are poorly understood. This study aimed to evaluate risk factors for the utilization of our centre's acute care radiation nursing clinic (RNC) by gynecologic oncology patients receiving radiotherapy (RT). METHODS This was a retrospective cohort study of gynecological cancer patients treated with RT at an academic cancer centre between 1 August 2021 and 31 January 2022. Data on socio-demographics, clinical and treatment characteristics, and RNC visits were collected and summarized by descriptive statistics. The Wilcoxon rank sum test and chi-squared test/Fisher's exact test were used for comparisons of continuous and categorical variables, respectively. RESULTS RT was delivered to 180 patients, of whom 42 (23%) received concurrent chemoradiation (CCR). Compared to those receiving RT alone, patients receiving CCR had higher rates of RNC utilization (55% vs. 19%, p < 0.001). Within the CCR cohort, patients who presented to the RNC were more likely to be unpartnered (43% vs. 11%, p = 0.04), receive a referral to Psychosocial Oncology (39% vs. 5.3%, p = 0.01), and experience treatment interruptions (52% vs. 16%, p = 0.02). There were no associations between RNC visits and age, disease site, or distance from the cancer centre. CONCLUSIONS The receipt of CCR and specific psychosocial risk factors were associated with increased RNC utilization. Targeted strategies and early intervention to better meet the supportive care and psychosocial needs of this vulnerable population are needed.

Longitudinal Costs of Image-Guided Intensity-Modulated Radiation Therapy Versus Three-Dimensional Conformal Radiation: Lessons From Phase III PARCER Trial for Shaping Resource-Stratified Guidelines in Low- and Middle-Income Countries. JCO Glob Oncol 2024; 10:e2300478. [PMID: 38484193 PMCID: PMC10954061 DOI: 10.1200/go.23.00478] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 01/23/2024] [Accepted: 02/01/2024] [Indexed: 03/19/2024] Open
Abstract
PURPOSE The PARCER trial provided level I evidence for image-guided intensity-modulated radiation therapy (IG-IMRT) in patients with cervical cancer. Further information regarding long-term financial impact is imperative for adoption into the National Cancer Grid of India cervical cancer resource-stratified guidelines. METHODS Patient data from the PARCER trial were analyzed to evaluate the cost implications of transitioning to IG-IMRT. Lacking differences in outcomes between the three-dimensional conformal radiation (3D-CRT) and IG-IMRT, differences in treatment costs, adverse event incidence, and toxicity management costs were examined. The overall financial impact was estimated by adding the treatment costs, toxicity management, and wage loss. This was extrapolated nationally to determine if a transition to IG-IMRT would be feasible for the Indian health care system. RESULTS Of the 300 patients in the PARCER trial, 93 faced grades ≥2 adverse events (3D-CRT = 59, IG-IMRT = 34). Patients in the 3D-CRT and IG-IMRT arms spent an average of 2.39 years and 1.96 years in toxicity, respectively. The average toxicity management and the yearly financial impact per patient were, respectively, 1.50 and 1.44 times higher for 3D-CRT patients compared with IG-IMRT patients. Extrapolation to the national level showed that treatment with 3D-CRT led to a 2.88 times higher cost ratio when compared with treatment with IG-IMRT. CONCLUSION Although the initial costs of IG-IMRT are high, on the basis of longitudinal data, it is financially inefficient to treat with 3D-CRT. Resource-stratified guidelines should include longitudinal health intervention costs rather than solely initial costs for policy decisions to implement advanced radiation technology.

Technol Cancer Res Treat 2024; 23:15330338241263026. [PMID: 39043041 PMCID: PMC11271135 DOI: 10.1177/15330338241263026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 05/08/2024] [Accepted: 05/24/2024] [Indexed: 07/25/2024] Open
Abstract
BACKGROUND This study aims to assess the efficacy and safety of Endostar in the management of locally advanced cervical cancer. METHODS This retrospective, 2-center study enrolled 41 patients with locally advanced cervical cancer between June 2017 and December 2020. The patients were subjected to a combination of Endostar and chemoradiotherapy until they experienced disease progression or an unacceptable level of toxicity. The patients in the Endostar combined chemoradiotherapy (E + CRT) and CRT groups were matched 1:1 based on clinical features, including age, disease stage, and pathological type. The therapeutic efficacy and safety outcomes were compared between the 2 groups. RESULTS Early treatment response: the CR rates in E + CRT and CRT groups were 48.8% and 26.8%, respectively (χ2 = 4.20, P < .05). The ORR and DCR were not significantly different between the 2 groups. Long-term efficacy: there was no significant difference in the 1-year and 2-year PFS rates and OS rates between 2 groups. However, in patients with stage IIB, subgroup analyses revealed a significant difference in PFS between the 2 groups (P < .05). Prognostic factors: stage, Eastern Cooperative Oncology Group (ECOG) score, and tumor size were independent predictive factors for PFS, while ECOG score and tumor size were those of OS in patients with locally advanced cervical cancer. Safety: The incidence of grade III-IV myelosuppression was significantly lower in E + CRT group than in CRT group (P < .05). CONCLUSIONS The combination of Endostar and concurrent CRT exhibited greater efficacy in treating locally advanced cervical cancer with no severe adverse reactions, when compared to simple CRT. It is expected that this approach will evolve into a new treatment alternative for patients with locally advanced cervical cancer.

Abstract
In this article, we report the design and demonstration of a flexible coaxial wire antenna with a low profile flexible choke for delivering localized hyperthermia (HT) treatment to the cervix through a custom designed uterine tandem applicator. Resistive and magnetic materials were investigated for determining the flexible choke design suited for intracavitary HT treatment at 915 MHz. Measurements of the intracavitary antenna with the flexible choke in tissue mimicking phantom and ex-vivo bovine muscle through the non-metallic uterine tandem prototype confirm the ability to deliver localized HT to the cervix at 915 MHz and 50 mm insertion depth.

Abstract
PURPOSE To analyze the effect of cisplatin cycles on the clinical outcomes of patients with locally advanced cervical cancer (LACC) treated with concurrent chemoradiotherapy (CCRT). METHODS This study included 749 patients with LACC treated with CCRT between January 2011 and December 2015. A receiver operating characteristic (ROC) curve was used to analyze the optimal cut-off of cisplatin cycles in predicting clinical outcomes. Clinicopathological features of the patients were compared using the Chi-square test. Prognosis was assessed using log-rank tests and Cox proportional hazard models. Toxicities were compared among different cisplatin cycle groups. RESULTS Based on the ROC curve, the optimal cut-off of the cisplatin cycles was 4.5 (sensitivity, 64.3%; specificity, 54.3%). The 3-year overall, disease-free, loco-regional relapse-free, and distant metastasis-free survival for patients with low-cycles (cisplatin cycles < 5) and high-cycles (≥ 5) were 81.5% and 89.0% (P < 0.001), 73.4% and 80.1% (P = 0.024), 83.0% and 90.8% (P = 0.005), and 84.9% and 86.8% (P = 0.271), respectively. In multivariate analysis, cisplatin cycles were an independent prognostic factor for overall survival. In the subgroup analysis of high-cycle patients, patients who received over five cisplatin cycles had similar overall, disease-free, loco-regional relapse-free, and distant metastasis-free survival to patients treated with five cycles. Acute and late toxicities were not different between the two groups. CONCLUSION Cisplatin cycles were associated with overall, disease-free, and loco-regional relapse-free survival in LACC patients who received CCRT. Five cycles appeared to be the optimal number of cisplatin cycles during CCRT.

Abstract
PURPOSE In locally advanced cervical cancer (LACC), adding cisplatin to radiotherapy (RT) improves survival but increases toxicity. Among patients with cisplatin contraindications, RT compliance may be compromised by toxicity because of cisplatin or a substitute. In shared decision making, a patient decision aid (PtDA) may decrease decisional conflict and attitudinal barriers, thereby improving treatment compliance. METHODS Following International Patient Decision Aid Standards (IPDAS) guidelines, a steering committee of two radiation oncologists, a gynecologic oncologist, an oncology nurse, a clinical psychologist, a cancer survivor, and a caregiver developed the chemotherapy or exclusion in cisplatin-intolerant patients with LACC (CECIL) prototype, a PtDA for cisplatin-intolerant patients with LACC deciding about adding chemotherapy to RT. The prototype was alpha-tested using the e-Delphi method. The patient decision aid research group Ottawa Acceptability Questionnaire was used to evaluate comprehensibility, length, amount of information, neutrality, and overall suitability for decision making. The prototype was then independently evaluated by local internal, local external, and international reviewers using the IPDAS checklist version 4, which encompasses information, probabilities, values, guidance, development, evidence, disclosure, plain language, and evaluation. RESULTS Alpha testing showed high practitioner acceptability (all items with mean and median scores ≥4; overall mean score 4.70 of 5.00) and good patient acceptability (all items rated good to excellent). Content validation showed that the PtDA satisfied all IPDAS six qualifying and six certification criteria, with high overall mean score (3.63 of 4.00) for all 17 applicable quality criteria. CONCLUSION The CECIL prototype shows good practitioner and patient acceptability, and content validity on peer review. Clinical testing to determine its effectiveness in reducing decisional conflict is ongoing.

Abstract
This retrospective study identified prognostic factors to help guide the clinical treatment of elderly patients (≥ 65 years) with cervical cancer who had undergone radiotherapy. A personalized model to predict 3- and 5-years survival was developed. A review was conducted of 367 elderly women with cervical cancer (staged II-III) who had undergone radiotherapy in our hospital between January 2012 and December 2016. The Cox proportional hazards regression model was used for survival analysis that considered age, hemoglobin, squamous cell carcinoma antigen, pathologic type, stage, pelvic lymph node metastasis status, and others. A nomogram was constructed to predict the survival rates. The median follow-up time was 71 months (4-118 months). The 3- (5-) years overall, progression-free, local recurrence-free, and distant metastasis-free survival rates were, respectively, 91.0% (84.4%), 92.3% (85.9%), 99.18% (99.01%), and 99.18% (97.82%). The following were significant independent prognostic factors for overall survival: tumor size, pre-treatment hemoglobin, chemotherapy, and pelvic lymph node metastasis. The C-index of the line chart was 0.699 (95% CI 0.652-0.746). The areas under the receiver operating characteristic curves for 3- and 5-years survival were 0.751 and 0.724. The nomogram was in good concordance with the actual survival rates. The independent prognostic factors for overall survival in elderly patients with cervical cancer after radiotherapy were: tumor size, pre-treatment hemoglobin, chemotherapy, and pelvic lymph node metastasis. The novel prognostic nomogram based on these factors showed good concordance with the actual survival rates and can be used to guide personalized clinical treatment.

Abstract
BACKGROUND The European Society of Gynaecological Oncology (ESGO) has previously defined and established a list of quality indicators for the surgical treatment of cervical cancer. As a continuation of this effort to improve overall quality of care for cervical cancer patients across all aspects, ESGO and the European SocieTy for Radiotherapy and Oncology (ESTRO) initiated the development of quality indicators for radiation therapy of cervical cancer. OBJECTIVE To develop a list of quality indicators for radiation therapy of cervical cancer that can be used to audit and improve clinical practice by giving to practitioners and administrators a quantitative basis to improve care and organizational processes, notably for recognition of the increased complexity of modern external radiotherapy and brachytherapy techniques. METHODS Quality indicators were based on scientific evidence and/or expert consensus. The development process included a systematic literature search for identification of potential quality indicators and documentation of scientific evidence, consensus meetings of a group of international experts, an internal validation process, and external review by a large international panel of clinicians (n = 99). RESULTS Using a structured format, each quality indicator has a description specifying what the indicator is measuring. Measurability specifications are detailed to define how the quality indicators will be measured in practice. Targets were also defined for specifying the level which each unit or center should be aiming to achieve. Nineteen structural, process, and outcome indicators were defined. Quality indicators 1-6 are general requirements related to pretreatment workup, time to treatment, upfront radiation therapy, and overall management, including active participation in clinical research and the decision making process within a structured multidisciplinary team. Quality indicators 7-17 are related to treatment indicators. Quality indicators 18 and 19 are related to patient outcomes. DISCUSSION This set of quality indicators is a major instrument to standardize the quality of radiation therapy in cervical cancer. A scoring system combining surgical and radiotherapeutic quality indicators will be developed within an envisaged future ESGO accreditation process for the overall management of cervical cancer, in an effort to support institutional and governmental quality assurance programs.

Abstract
BACKGROUND The European Society of Gynaecological Oncology (ESGO) has previously defined and established a list of quality indicators for the surgical treatment of cervical cancer. As a continuation of this effort to improve overall quality of care for cervical cancer patients across all aspects, ESGO and the European SocieTy for Radiotherapy and Oncology (ESTRO) initiated the development of quality indicators for radiation therapy of cervical cancer. OBJECTIVE To develop a list of quality indicators for radiation therapy of cervical cancer that can be used to audit and improve clinical practice by giving to practitioners and administrators a quantitative basis to improve care and organizational processes, notably for recognition of the increased complexity of modern external radiotherapy and brachytherapy techniques.

[PMID: 37325638 PMCID: PMC10262918 DOI: 10.3389/fimmu.2023.1193222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Accepted: 05/16/2023] [Indexed: 06/17/2023] Open
Abstract
Introduction Immune checkpoint inhibitors (ICIs) are monoclonal antibodies that target immune checkpoints that suppress immune cell activity. Low efficiency and high resistance are currently the main barriers to their clinical application. As a representative technology of targeted protein degradation, proteolysis-targeting chimeras (PROTACs) are considered to have potential for addressing these limitations. Methods We synthesized a stapled peptide-based PROTAC (SP-PROTAC) that specifically targeted palmitoyltransferase ZDHHC3 and resulted in the decrease of PD-L1 in human cervical cancer cell lines. Flow cytometry, confocal microscopy, protein immunoblotting, Cellular Thermal Shift Assay (CETSA), and MTT assay analyses were conducted to evaluate the effects of the designed peptide and verify its safety in human cells. Results In cervical cancer celllines C33A and HeLa, the stapled peptide strongly downregulated PD-L1 to < 50% of baseline level at 0.1 μM. DHHC3 expression decreased in both dosedependentand time-dependent manners. MG132, the proteasome inhibitor, can alleviate the SP-PROTAC mediated degradation of PD-L1 in human cancer cells. In a co-culture model of C33A and T cells, treatment with the peptide induced IFN-γ and TNF-α release in a dose-dependent manner by degrading PD-L1. These effects were more significant than that of the PD-L1 inhibitor, BMS-8. Conclusions Cells treated with 0.1 μM of SP-PROTAC or BMS-8 for 4 h revealed that the stapled peptide decreased PD-L1 more effectively than BMS-8. DHHC3-targeting SP-PROTAC decreased PD-L1 in human cervical cancer more effectively than the inhibitor BMS-8.

Abstract
OBJECTIVE Radiotherapy plays a vital role as a treatment for malignant pelvic tumors, in which the bladder represents a significant organ at risk involved during tumor radiotherapy. Exposing the bladder wall to high doses of ionizing radiation is unavoidable and will lead to radiation cystitis (RC) because of its central position in the pelvic cavity. Radiation cystitis will result in several complications (e.g. frequent micturition, urgent urination, and nocturia) that can significantly reduce the patient's quality of life and in very severe cases become life-threatening. METHODS Existing studies on the pathophysiology, prevention, and management of radiation-induced cystitis from January 1990 to December 2021 were reviewed. PubMed was used as the main search engine. Besides the reviewed studies, citations to those studies were also included. RESULTS AND DISCUSSIONS In this review, the symptoms of radiation cystitis and the mainstream grading scales employed in clinical situations are presented. Next, preclinical and clinical research on preventing and treating radiation cystitis are summarized, and an overview of currently available prevention and treatment strategies as guidelines for clinicians is provided. Treatment options involve symptomatic treatment, vascular interventional therapy, surgery, hyperbaric oxygen therapy (HBOT), bladder irrigation, and electrocoagulation. Prevention includes filling up the bladder to remove it from the radiation field and delivering radiation based on helical tomotherapy and CT-guided 3D intracavitary brachytherapy techniques.

Abstract
BACKGROUND To evaluate the prognostic factors and oncologic outcome in patients with 2018 International Federation of Gynecology and Obstetrics (FIGO) stage IB cervical cancer (CC) after radical hysterectomy and lymphadenectomy. MATERIALS AND METHODS This study included 290 patients with type II or III radical hysterectomy + pelvic ± para-aortic lymphadenectomy and 2018 FIGO stage IB1-3 epithelial CC. Disease-free survival (DFS) estimates were determinate by using the Kaplan-Meier method. Survival curves were compared using the log-rank test. Multivariate analysis was performed using a Cox proportional hazards models. RESULTS The mean age of study cohort was 52 ± 10.25 years. Five-year DFS was 93% in entire cohort. On univariate analysis, surgical border involvement (p = 0.007), lymphovascular space invasion (LVSI) (p = 0.040), uterine involvement (p = 0.040), and depth of cervical stromal invasion (p = 0.007) were found to have statistical significance for DFS. However, none of them were independent prognostic factors for the risk of recurrence. Tumor size according to 2018 FIGO staging criteria was not related with recurrence. CONCLUSIONS Surgical border involvement, LVSI, depth of cervical stromal invasion, and uterine involvement were predictors for DFS on univariate analysis. Tumor size was not predicting to recurrence in patient with 2018 FIGO stage IB1-3 CC.

Díaz JFR. Cost analysis of three-dimensional radiation therapy versus intensity-modulated chemoradiotherapy for locally advanced cervical cancer in Peruvian citizens. Ecancermedicalscience 2023; 17:1531. [PMID: 37138970 PMCID: PMC10151083 DOI: 10.3332/ecancer.2023.1531] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Indexed: 05/05/2023] Open
Abstract
Background and objectives The standard treatment for locally advanced cervical cancer (CC) is chemoradiotherapy (CTRT) followed by high-dose-rate brachytherapy (HDRBT). The ideal scenario would be under novel intensity-modulated radiation therapy (IMRT) volumetric-modulated arc therapy (VMAT) radiation techniques over three-dimensional (3D) radiation therapy. However, radiotherapy (RT) centres in low- and middle-income countries have limited equipment for teletherapy services like HDRBT. This is why the 3D modality is still in use. The objective of this study was to analyse costs in a comparison of 3D versus IMRT versus VMAT based on clinical staging. Materials and methods From 02/01/2022 to 05/01/2023 a prospective registry of the costs for oncological management was carried out for patients with locally advanced CC who received CTRT ± HDRBT. This included the administration of radiation with chemotherapy. The cost associated with patient and family transfers and hours in the hospital was also identified. These expenses were used to project the direct and indirect costs of 3D versus IMRT versus VMAT. Results The treatment regimens for stage IIIC2, including 3D and novel techniques, are those with the highest costs. The administration of 3D RT for IIIC2 and novel IMRT or VMAT techniques, is $3,881.69, $3,374.76, and $2,862.80, respectively. The indirect cost from stage IIB to IIIC1 in descending order is IMRT, 3D and VMAT, but in IIIC2 the novel technique regimens reduce by up to 33.99% compared to 3D. Conclusion In RT centres with an available supply of RT equipment, VMAT should be preferred over IMRT/3D since it reduces costs and toxicity. However, in RT centres where demand exceeds supply in the VMAT technique planning systems, the use of 3D teletherapy over IMRT/VMAT could continue to be used in patients with stage IIB to IIIC1.

Abstract
Background Growing evidence suggests that nutritional status and inflammation are associated with survival in various cancers. This study aimed to evaluate the prognostic value of the prognostic nutritional index (PNI), geriatric nutritional risk index (GNRI), and systemic inflammatory indexes (neutrophil/lymphocyte ratio [NLR], monocyte/lymphocyte ratio [MLR], and platelet/lymphocyte ratio [PLR]) in patients with stage IIB-III cervical cancer receiving radiotherapy. Results The ideal cutoff values for the PNI, GNRI, NLR, MLR, and PLR were 48.3, 97.04, 2.8, 0.41, and 186.67, respectively. Low PNI and GNRI scores were associated with poor OS and PFS. High NLR, MLR, and PLR also predicted inferior 5-year OS and PFS rates in patients with stage IIB-III cervical cancer. Multivariate Cox regression analysis identified tumor size, histological type, stage, number of metastatic lymph nodes, PNI, GNRI, NLR, PLR, and MLR as significant prognostic factors for OS and PFS. Conclusions The current findings suggest that the PNI, GNRI, NLR, PLR, and MLR are essential parameters for predicting prognosis in patients with stage IIB-III cervical cancer receiving radiotherapy.

Abstract
Abstract
Objective: This retrospective study identified prognostic factors to help guide the clinical treatment of elderly patients (≥65 y) with cervical cancer who had undergone radiotherapy. A personalized model to predict 3- and 5-year survival was developed.
Methods: A review was conducted of 367 elderly women with cervical cancer (staged II-III) who had undergone radiotherapy in our hospital between January 2012 and December 2016. The Cox proportional hazards regression model was used for survival analysis that considered age, hemoglobin, squamous cell carcinoma antigen, pathologic type, stage, pelvic lymph node metastasis status, and others. A nomogram was constructed to predict the survival rates.
Results: The median follow-up time was 71 months (4-118 mo). The 3- (5-) year overall, progression-free, local recurrence-free, and distant metastasis-free survival rates were, respectively, 91.0% (84.4%), 92.3% (85.9%), 99.18% (99.01%), and 99.18% (97.82%). The following were significant independent prognostic factors for overall survival: tumor size, pre-treatment hemoglobin, chemotherapy, and pelvic lymph node metastasis. The C-index of the line chart was 0.699 (95% CI: 0.652-0.746). The areas under the receiver operating characteristic curves for 3- and 5-year survival were 0.751 and 0.724. The nomogram was in good concordance with the actual survival rates.
Conclusions: The independent prognostic factors for overall survival in elderly patients with cervical cancer after radiotherapy were: tumor size, pre-treatment hemoglobin, chemotherapy, and pelvic lymph node metastasis. The novel prognostic nomogram based on these factors can be an asset for personalized clinical management.

Abstract
AbstractUterine and ovarian cancers are the most common gynecologic cancers. N6−methyladenosine (m6A), an important internal RNA modification in higher eukaryotes, has recently become a hot topic in epigenetic studies. Numerous studies have revealed that the m6A-related regulatory factors regulate the occurrence and metastasis of tumors and drug resistance through various mechanisms. The m6A-related regulatory factors can also be used as therapeutic targets and biomarkers for the early diagnosis of cancers, including gynecologic cancers. This review discusses the role of m6A in gynecologic cancers and summarizes the recent advancements in m6A modification in gynecologic cancers to improve the understanding of the occurrence, diagnosis, treatment, and prognosis of gynecologic cancers.

Abstract
BACKGROUND AND PURPOSE MRI, applying dynamic contrast-enhanced (DCE) and diffusion-weighted (DW) sequences, and 18F-fluorodeoxyglucose (18F-FDG) PET/CT provide information about tumor aggressiveness that is unexploited in treatment of locally advanced cervical cancer (LACC). We investigated the potential of a multimodal combination of imaging parameters for classifying patients according to their risk of recurrence. MATERIALS AND METHODS Eighty-two LACC patients with diagnostic MRI and FDG-PET/CT, treated with chemoradiotherapy, were collected. Thirty-eight patients with MRI only were included for validation of MRI results. Endpoints were survival (disease-free, cancer-specific, overall) and tumor control (local, locoregional, distant). Ktrans, reflecting vascular function, apparent diffusion coefficient (ADC), reflecting cellularity, and standardized uptake value (SUV), reflecting glucose uptake, were extracted from DCE-MR, DW-MR and FDG-PET images, respectively. By applying an oxygen consumption and supply-based method, ADC and Ktrans parametric maps were voxel-wise combined into hypoxia images that were used to determine hypoxic fraction (HF). RESULTS HF showed a stronger association with outcome than the single modality parameters. This association was confirmed in the validation cohort. Low HF identified low-risk patients with 95% precision. Based on the 50th SUV-percentile (SUV50), patients with high HF were divided into an intermediate- and high-risk group with high and low SUV50, respectively. This defined a multimodality biomarker, HF/SUV50. HF/SUV50 increased the precision of detecting high-risk patients from 41% (HF alone) to 57% and showed prognostic significance in multivariable analysis for all endpoints. CONCLUSION Multimodal combination of MR- and FDG-PET/CT-images improves classification of LACC patients compared to single modality images and clinical factors.

Abstract
Cervical cancer (CC) is the fourth leading cause of death in women worldwide and despite the introduction of screening programs about 30% of patients presents advanced disease at diagnosis and 30-50% of them relapse in the first 5-years after treatment. According to FIGO staging system 2018, stage IB3-IVA are classified as locally advanced cervical cancer (LACC); its correct therapeutic choice remains still controversial and includes neoadjuvant chemo-radiotherapy, external beam radiotherapy, brachytherapy, hysterectomy or a combination of these modalities. In this review we focus on the most appropriated therapeutic options for LACC and imaging protocols used for its correct follow-up. We explore the imaging findings after radiotherapy and surgery and discuss the role of imaging in evaluating the response rate to treatment, selecting patients for salvage surgery and evaluating recurrence of disease. We also introduce and evaluate the advances of the emerging imaging techniques mainly represented by spectroscopy, PET-MRI, and radiomics which have improved diagnostic accuracy and are approaching to future direction.

Abstract
AIMS Patient factors affect the risk of radiotherapy toxicity, but many are poorly defined. Studies have shown that race affects cancer incidence, survival, drug response, molecular pathways and epigenetics. Effects on radiosensitivity and radiotherapy toxicity are not well studied. The aim of the present study was to identify the effects of race and ethnicity on the risk of radiotherapy toxicity. MATERIALS AND METHODS A systematic review was carried out of PubMed, Ovid Medline and Ovid Embase with no year limit. PRISMA 2020 guidelines were followed. Two independent assessors reviewed papers. RESULTS Of 607 papers screened, 46 fulfilled the inclusion criteria. Papers were published between 1996 and 2021 and involved 30-28,354 individuals (median 433). Most involved patients with prostate (33%), breast (26%) and lung (9%) cancer. Both early and late toxicities were studied. Some studies reported a higher risk of toxicity in White men with prostate cancer compared with other races and ethnicities. For breast cancer patients, some reported an increased risk of toxicity in White women compared with other race and ethnic groups. In general, it was difficult to draw conclusions due to insufficient reporting and analysis of race and ethnicity in published literature. CONCLUSIONS Reporting of race and ethnicity in radiotherapy studies must be harmonised and improved and frameworks are needed to improve the quality of reporting. Further research is needed to understand how ancestral heritage might affect radiosensitivity and risk of radiotherapy toxicity.

Abstract
Cervical cancer has a high incidence of malignant tumors and a high mortality rate, with squamous cervical carcinoma (SCC) accounting for 80% of cases. A competing-risks model is recommended as being more feasible for evaluating the prognosis and guiding clinical practice in the future compared to Cox regression. Data originating from the Surveillance, epidemiology, and end results (SEER) database during 2004 to 2013 were analyzed. Univariate analysis with the cumulative incidence function was performed to assess the potential risk of each covariate. Significant covariates (P < .05) were extracted for inclusion in a Cox regression analysis and a competing-risks model that included a cause-specific (CS) hazard function model and a sub-distribution (SD) hazard function model. A total of 5591 SCC patients met the inclusion criteria. The three methods (Cox regression analysis, CS analysis, and SD analysis) showed that age, metastasis, American Joint Committee on Cancer stage, surgery, chemotherapy, radiation sequence with surgery, lymph node dissection, tumor size, and tumor grade were prognostic factors affecting survival in patients with SCC. In contrast, race and radiation status were prognostic factors affecting survival in the Cox regression and CS analysis, but the results were different in the SD analysis. Being separated, divorced, or widowed was an independent prognostic factor in the Cox regression analysis, but the results were different in the CS and SD analyses. A competing-risks model was used as a new statistical method to more accurately identify prognostic factors than conventional Cox regression analysis leading to bias in the results. This study found that the SD model may be better suited to estimate the clinical prognosis of a patient, and that the results of an SD model analysis were close to those of a CS analysis.

Abstract
p28 is a natural bacterial product, which recently has attracted much attention as an efficient cell penetrating peptide (CPP) and a promising anticancer agent. Considering the interesting biological qualities of p28, maximizing its expression appears to be a prominent priority. The optimization of such bioprocesses might be facilitated by utilizing statistical approaches such as Design of Experiment (DoE). In this study, we aimed to maximize the expression of "biologically active" p28 in Escherichia coli BL21 (DE3) host by harnessing statistical tools and experimental methods. Using Minitab, Plackett-Burman and Box-Behnken Response Surface Methodology (RSM) designs were generated to optimize the conditions for the expression of p28. Each condition was experimentally investigated by assessing the biological activity of the purified p28 in the MCF-7 breast cancer cell line. Seven independent variables were investigated, and three of them including ethanol concentration, OD600 of the culture at the time of induction, and the post-induction temperature were demonstrated to significantly affect the p28 expression in E. coli. The cytotoxicity, penetration efficiency, and total process time were measured as dependent variables. The optimized expression conditions were validated experimentally, and the final products were investigated in terms of expression yield, solubility, and stability in vitro. Following the optimization, an 8-fold increase of the concentration of p28 expression was observed. In this study, we suggest an optimized combination of effective factors to produce soluble p28 in the E. coli host, a protocol that results in the production of a significantly high amount of the biologically active peptide with retained solubility and stability.

Vaginal 11-point and volumetric dose related to late vaginal complications in patients with cervical cancer treated with external beam radiotherapy and image-guided adaptive brachytherapy. Radiother Oncol 2022; 174:77-86. [PMID: 35839936 DOI: 10.1016/j.radonc.2022.07.009] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 07/06/2022] [Accepted: 07/07/2022] [Indexed: 10/17/2022]
Abstract
OBJECTIVE To investigate the vaginal 11-point and volumetric dose-toxicity relationships in definitive cervical cancer radiotherapy. METHODS A retrospective cohort study of patients with cervical cancer with a complete response of at least 12 months was performed. Additional per vaginal examinations and patient-scoring questionnaires on the date of patient enrolment were assessed for vaginal strictures. Retrospective dosimetric analysis of vaginal 11-point and volumetric doses was performed with descriptive and probit analyses to investigate dose-toxicity relationships. RESULTS Ninety-seven patients were included in the study, with a 20-month median follow-up. The incidence rate of grade 3 vaginal strictures was 22.7%. A comparison between patients with grade 1-3 vaginal strictures revealed significant differences in age, stage, initial tumour size, and vaginal involvement. PIBS + 2, PIBS, PIBS-2, D + 5, and D2cc were all significantly different among grade 1-3 vaginal strictures and showed significant probit coefficients. The lateral dose points were significantly higher in grade 2 strictures, but negative probit coefficients failed to establish causal inferences. Post-estimation analyses yielded effective doses (ED) for 15% and 20% probability of grade 3 vaginal strictures (ED15 and ED20) for PIBS + 2 at 57.4 and 111 Gy3, respectively. PIBS-2 yielded an ED20 of 7 Gy3. D + 5 yielded positive ED10, ED15, and ED20 values of 52.2, 66.6, and 78 Gy3, respectively. CONCLUSIONS This study showed a significant relationship between age, tumour size, and lower-third vaginal involvement with the incidence of vaginal toxicity. The goal of a cumulative radiotherapy dose of ≤ 55 Gy3 to PIBS + 2, ≤5 Gy3 to PIBS-2, and ≤ 65 Gy3 to D + 5 points may reduce the risk of grade 3 vaginal stenosis to less than 15-20%.

Abstract
The aims of this study were to investigate the short-term and long-term efficacies and chronic radiotoxicity of concurrent chemoradiotherapy (CCRT) combined with image-guided adaptive brachytherapy (IGABT) in patients with locally advanced cervical cancer (LACC) and identify prognostic factors in this patient population. The clinical data of 204 patients with cervical cancer who completed CCRT and subsequent brachytherapy in our hospital between February 2015 and March 2017 were retrospectively analyzed. Short-term and long-term outcomes, chronic radiotoxicity, and prognostic factors were assessed. The median follow-up was 61.1 months. The short-term objective response (OR) rate was 85%. Lymph node metastasis before treatment was an independent predictor of OR (HR = 6.290, 95% CI: 2.211-17.897, p = 0.001). Fifty-two patients developed recurrence, with a median recurrence-free survival of 9.9 months (range, 2.4-52.2 months) and a post-recurrence survival of 12.1 months (range, 2.9-58.1 months). At 3 years, the cumulative incidence of overall recurrence was 26% (95% CI: 17-36). Multivariate analysis showed that Stage IIIB (HR = 2.332, 95% CI: 1.195-4.551, p = 0.013; reference, Stage IIB) and lymph node metastasis (HR = 4.462, 95% CI: 2.365-8.419, p < 0.001) were significant independent predictors of recurrence. Fifty-three patients developed chronic radiation proctitis (CRP). The incidence of severe CRP was approximately 5%, and the average rectal D2cm3 accumulation in patients with severe CRP was 73.4 Gy which is 3.9 Gy higher than that in patients without CRP (p = 0.013). At 4 years, the overall survival (OS) and disease-free survival rates were 65% and 62%, respectively, and lymph node metastasis before treatment was an independent prognostic risk factor for OS. The short-term and long-term efficacies of CCRT combined with IGABT for the treatment of LACC patients were relatively satisfactory. However, the short-term and long-term efficacies of patients with lymph node metastasis before treatment were poor. For patients with lymph node metastasis before treatment, more active individualized treatment strategies should be adopted. When designing a radiotherapy plan, it is necessary to strictly limit the rectal D2cm3 accumulation to prevent serious CRP.

Outcomes with definitive radiotherapy among patients with locally advanced cervical cancer with relative or absolute contraindications to cisplatin: A systematic review and meta-analysis. Gynecol Oncol 2022; 166:614-630. [PMID: 35760651 DOI: 10.1016/j.ygyno.2022.06.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Revised: 06/16/2022] [Accepted: 06/20/2022] [Indexed: 11/04/2022]
Abstract
BACKGROUND The standard treatment for locally advanced cervical cancer (LACC) is chemoradiation (CRT) with cisplatin, followed by brachytherapy, but is less defined for cisplatin-intolerant patients. We synthesized evidence on treatment outcomes with definitive radiotherapy (RT) with or without chemotherapy (ChT) in these patients. METHODS We performed a systematic search and included 20 relevant studies. We extracted data on response, survival, compliance, and toxicity, and performed meta-analyses of outcome rates and risk ratios. Sensitivity and subgroup analyses were performed to explore sources of heterogeneity. Meta-regression was performed to examine the effects of other variables. RESULTS Due to lack of comparative data, most comparisons were indirect and derived from the proportional meta-analyses. Complete response (85%) and survival (62% 5yOS) rates are comparable to those published for LACC without contraindications to cisplatin. Survival rate is better with CRT than RT alone (5yOS, 73% vs 58%), and with nodal boost (NB) than without (5yOS, 71% vs 56%). Carboplatin CRT is associated with lower 5yOS (44%) but better ChT compliance (86%) when compared to other interventions. ChT compliance is better in renal failure than elderly cohorts (89% vs 67%). RT compliance is lower with CRT than RT alone (90% vs 96%), and higher with NB than none (96% vs 93%). NB is associated with lower RT compliance than no NB, when ChT is given. Meta-regression results affirm ChT and NB to be significant positive factors for survival, and NB, which is associated with greater use of advanced RT techniques, for RT compliance. CONCLUSION For those with relative contraindications, cisplatin CRT is effective and well-tolerated. For those with absolute contraindications, carboplatin is well-tolerated but with unclear effectiveness. Nodal boost is effective and well-tolerated, but is less tolerated when concurrent ChT is given.

Abstract
BACKGROUND The standard treatment for locally advanced cervical cancer (LACC) is concurrent chemoradiation (CRT) followed by brachytherapy (BRT). The addition of chemotherapy (ChT) to radiotherapy (RT) is associated with a 7.5% improvement in overall survival but with more grade 3-4 acute toxicities (16.4% vs 4.9%, CRT vs RT alone). The risk-benefit ratio could be less favorable in advanced disease with renal dysfunction secondary to tumor-related hydronephrosis; borderline cardiac function; and frail patients. RT alone followed by BRT achieves long-term locoregional control <62%. Hypofractionated RT (HF-RT) using older techniques result in comparable disease control and low late toxicity rates (4-8%). Dose-adapted HF-RT using intensity-modulated RT with nodal simultaneous integrated boost (nSIB) could improve tumor control and toxicity, when ChT is contraindicated. METHODS The HYACINCT study is a two-phase study to determine the effectiveness and safety of HF-RT with nSIB in LACC when ChT is contraindicated. Phase 1 is a dose-escalation study using standard 3 + 3 design, to determine the maximum tolerated dose (MTD) for nSIB in combination with pelvic HF-RT (2.67 Gy x 15 fractions). Phase 2 is a single-arm clinical trial using Simon's two-stage design, to assess the efficacy of HF-RT with nSIB in terms of tumor response. Adult women with biopsy-proven, untreated LACC, with contraindication to ChT will be included in this trial. DISCUSSION For the phase 1, the primary endpoint is dose-limiting toxicity (DLT), or any grade ?3 acute or sub-acute toxicity. The dose level at which incidence of DLT is ?33% is defined as the maximum tolerance dose (MTD). For the phase 2, the primary endpoint is complete response at 3 months post-treatment. Secondary outcomes are progression-free and overall survival, acute and late toxicity, and patient-reported outcomes (EPIC, EORTCQLQ C30 + CX24, PGIC, PCIS). Trial registration: NCT05210270.

Abstract
Cervical cancer, a common cancer in women, has become a serious social burden. Kinetochore-associated protein 1 (KNTC1) that regulates the cell cycle by regulating mitosis is related to the malignant behavior of different types of tumors. However, its role in the development of cervical cancer remains unclear. In this study, we initially explored the role of KNTC1 in cervical cancer. KNTC1 expression and relevant information were downloaded from The Cancer Genome Atlas (TCGA) and dataset GSE63514 in the Gene Expression Omnibus (GEO) database for bioinformatics analyses. Cell proliferation was detected by cell counting kit-8 (CCK8) and colony formation assays. Wound healing and Transwell assays were used to evaluate cell migration and invasion abilities. Protein expression levels of matrix metallopeptidase 2 (MMP2) and matrix metallopeptidase 9 (MMP9) were measured by western blotting. Nude mouse models of subcutaneous xenograft tumor were constructed to analyze tumor growth in vivo. CCK8 and colony formation assay results demonstrated that the proliferation rate of SiHa and C-33A cells decreased when KNTC1 was silenced. Western blot and Transwell assays indicated that KNTC1 knockdown weakened the invasion and migration abilities of SiHa and C-33A cells and decreased the expression of MMP-2 and MMP-9. In-vivo experiments suggested that the inhibition of KNTC1 reduced tumor growth. Taken together, our study showed that KNTC1 plays an important role in cervical cancer. Further, we verified the promotional effect of KNTC1 on cervical cancer through in-vivo and in-vitro experiments and speculated that KNTC1 might mediate tumor invasion via MMP9 and MMP2.

Abstract
Cervical cancer represents a significant portion of the global cancer burden for women, with low- and middle-income countries carrying the bulk of this burden. Additionally, underserved populations in countries with sufficient resources may have a higher incidence of cervical cancer and poorer outcomes. Concurrent chemoradiotherapy is the standard-of-care treatment for locally advanced cervical cancer, which includes patients with stage IB3 to IVA disease, and it is effective for many patients; however, cervical cancer-related mortality remains high. The critical nature of cervical cancer treatment is underscored by the recent launch of the World Health Organization global initiative to accelerate the elimination of cervical cancer using a triple-intervention strategy of increased vaccination, screening, and treatment. The initiative calls for 90% of all patients diagnosed with cervical cancer to receive the appropriate treatment, but to reach this global goal there are significant barriers related to radiotherapy that must be addressed. We discuss and review evidence of the lack of adherence to guideline-recommended treatment, brachytherapy underutilization, limited access to radiotherapy in low- and middle-income countries, as well as regional limitations within high-income countries, as the major barriers to radiotherapy treatment for locally advanced cervical cancer. We further review ways these barriers are currently being addressed and, in some cases, make additional recommendations to address these issues. Finally, despite receiving recommended treatments, many patients with locally advanced cervical cancer have a poor prognosis. With effective administration of current standards of care, the global community will be able to shift focus to advancing treatment efficacy for these patients. We review several types of therapies under clinical investigation that are additions to concurrent chemoradiotherapy, including immune checkpoint inhibitors, antiangiogenic agents, DNA repair inhibitors, human papillomavirus vaccines, and radiosensitizing nanoparticles.

Pre-treatment hematological parameters as a cost effective predictive marker for response to concurrent chemo radiation in locally advanced cervical cancer. Cancer Treat Res Commun 2022; 31:100539. [PMID: 35220070 DOI: 10.1016/j.ctarc.2022.100539] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Revised: 04/06/2021] [Accepted: 02/20/2022] [Indexed: 12/24/2022]
Abstract
INTRODUCTION Locally advanced cervical cancer is still a major cause of mortality in developing countries. Recently, personalized medicine has changed the treatment paradigm for many solid cancers but no robust biomarkers has yet been validated for predicting response to chemo radiation in cervical cancer patients. AIM To assess the role of hematological parameters as a cost-effective predictive marker of response to concurrent chemo radiation in cervical cancer patients. MATERIALS AND METHOD This is a retrospective analysis of 90 cervical cancer patients treated with concurrent chemo radiation in a tertiary cancer center. Clinical details of the patients were extracted from the case records. For end point evaluation, the pre-treatment levels of hemoglobin, neutrophil, lymphocyte, platelet, platelet lymphocyte ratio (PLR) and neutrophil lymphocyte ratio (NLR) were compared and statistically analyzed between responders and non-responders. The optimal cutoff values of hematological parameters were estimated by the receiver operating characteristics (ROC) curve. RESULT Out of 90 patients, 60 (66.66%) were complete responders and remaining 30 (33.33%) were non-responders. The mean value of platelet, NLR, and PLR was significantly higher in the non-responder group. ROC curve analysis showed the optimal cut-off value of pre-treatment Hb, PLT, NLR and PLR to be 11 gm/dl, 3, 177 × 109/L, and 70 respectively. CONCLUSION Our study suggests that simple hematological markers like NLR, PLT count and PLR could be used as a cost effective pretreatment predictive marker for response to chemo radiation in cervical cancer patients.

Diagnostic Framework of Pelvic Massive Necrosis with Peritonitis following Chemoradiation for Locally Advanced Cervical Cancer: When Is the Surgery Not Demandable? A Case Report and Literature Review. Diagnostics (Basel) 2022; 12:diagnostics12020440. [PMID: 35204530 PMCID: PMC8871003 DOI: 10.3390/diagnostics12020440] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Revised: 02/05/2022] [Accepted: 02/07/2022] [Indexed: 11/16/2022] Open
Abstract
Concurrent platinum-based chemoradiation (CCRT) is the established treatment for locally advanced cervical cancer and has an acceptable toxicity. Radiation-induced necrosis of the uterus and pelvic tissue is a rare and usually late potential complication. Limited data are available about its management. Here, we describe a case of a patient affected by a locally advanced cervical cancer (stage IVA) who received CCRT, obtaining a partial response with persistence of bladder and rectal infiltration. Unfortunately, after the first brachytherapy dose, the patient developed a worsening clinical picture with fever and altered laboratory data indicative of sepsis; the computed tomography revealed a massive necrosis of the uterus with pelvic abscess and peritonitis. We performed a laparoscopic emergency surgery with removal of the necrotic tissue, supracervical hysterectomy, bilateral-oophorectomy, and abscess drainage. Thereafter, once the severe inflammatory condition was resolved, the patient underwent pelvic exenteration with palliative/curative intent. The postoperative PET/CT was negative for residual disease. However, the patient needed further hospitalization for re-occurrence of peritonitis with multiple abscesses. A careful diagnosis is crucial in locally advanced cervical cancer patients who, after CCRT, present persistent pain and problematic findings at imaging and laboratory parameters. In these cases, radiation-induced necrosis of the pelvis should be suspected. This case helps to clarify the central role of surgery, especially when actinic necrosis leads to complications such as abscess, fistulae, and extensive tissue destruction that cannot be conservatively medically handled. Laparoscopy represents an ideal approach to realizing the correct diagnosis, as well as enabling the performance of important therapeutic surgical procedures.

Dose-Intense Cisplatin-Based Neoadjuvant Chemotherapy Increases Survival in Advanced Cervical Cancer: An Up-to-Date Meta-Analysis. Cancers (Basel) 2022; 14:cancers14030842. [PMID: 35159111 PMCID: PMC8834199 DOI: 10.3390/cancers14030842] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 01/31/2022] [Accepted: 02/01/2022] [Indexed: 02/04/2023] Open
Abstract
Simple Summary Although neoadjuvant chemotherapy has become standard care for many locally advanced cancer sites, the benefit of neoadjuvant chemotherapy remains unclear for the treatment of locally advanced cervical cancer. With this meta-analysis, we set out to demonstrate the benefit of using dose-intense cisplatin-based neoadjuvant chemotherapy in terms of overall survival and progression-free survival. Dose-intense cisplatin-based neoadjuvant chemotherapy followed by local therapy was significantly associated with a survival benefit in the treatment of locally advanced cervical carcinoma. Even though radiotherapy combined with weekly cisplatin-based chemotherapy remains standard of care for the treatment of locally advanced cervical cancer, our meta-analysis makes it possible to consider the use of dose-intense cisplatin-based neoadjuvant chemotherapy when local treatment is suboptimal and opens perspectives for designing new clinical trials in this setting. Abstract Purpose: We set out to demonstrate the benefit of using dose-intense cisplatin-based neoadjuvant chemotherapy in terms of overall survival and progression-free survival. Methods: We searched through MEDLINE and Cochrane Library databases up to May 2021 to identify randomized clinical trials comparing the benefit of using cisplatin-based neoadjuvant chemotherapy followed by local treatment with local treatment alone for the treatment of locally advanced cervical cancer. The PRISMA statement was applied. Results: Twenty-two randomized clinical trials were retrieved between 1991 and 2019, corresponding to 3632 women with FIGO stages IB2-IVA cervical cancer. More than 50% of the randomized clinical trials were assessed as having a low risk of bias. There was no benefit of neoadjuvant chemotherapy on overall survival, but there was significant heterogeneity across studies (I2 = 45%, p = 0.01). In contrast, dose-intense cisplatin at over 72.5 mg/m2/3 weeks was significantly associated with increased overall survival (RR = 0.87, p < 0.05) with no heterogeneity across the pooled studies (I2 = 36%, p = 0.11). The survival benefit was even greater when cisplatin was administered at a dose over 105 mg/m2/3 weeks (RR = 0.79, p < 0.05). Conclusion: Even though radiotherapy combined with weekly cisplatin-based chemotherapy remains standard of care for the treatment of locally advanced cervical cancer, our meta-analysis makes it possible to consider the use of dose-intense cisplatin-based neoadjuvant chemotherapy when local treatment is suboptimal and opens perspectives for designing new clinical trials in this setting. Neoadjuvant chemotherapy could be proposed when surgery is local treatment instead of standard chemoradiotherapy for the treatment of locally advanced cervical cancer.

Hyperthermia: A Potential Game-Changer in the Management of Cancers in Low-Middle-Income Group Countries. Cancers (Basel) 2022; 14:cancers14020315. [PMID: 35053479 PMCID: PMC8774274 DOI: 10.3390/cancers14020315] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2021] [Revised: 12/30/2021] [Accepted: 01/05/2022] [Indexed: 02/04/2023] Open
Abstract
Loco-regional hyperthermia at 40-44 °C is a multifaceted therapeutic modality with the distinct triple advantage of being a potent radiosensitizer, a chemosensitizer and an immunomodulator. Risk difference estimates from pairwise meta-analysis have shown that the local tumour control could be improved by 22.3% (p < 0.001), 22.1% (p < 0.001) and 25.5% (p < 0.001) in recurrent breast cancers, locally advanced cervix cancer (LACC) and locally advanced head and neck cancers, respectively by adding hyperthermia to radiotherapy over radiotherapy alone. Furthermore, thermochemoradiotherapy in LACC have shown to reduce the local failure rates by 10.1% (p = 0.03) and decrease deaths by 5.6% (95% CI: 0.6-11.8%) over chemoradiotherapy alone. As around one-third of the cancer cases in low-middle-income group countries belong to breast, cervix and head and neck regions, hyperthermia could be a potential game-changer and expected to augment the clinical outcomes of these patients in conjunction with radiotherapy and/or chemotherapy. Further, hyperthermia could also be a cost-effective therapeutic modality as the capital costs for setting up a hyperthermia facility is relatively low. Thus, the positive outcomes evident from various phase III randomized trials and meta-analysis with thermoradiotherapy or thermochemoradiotherapy justifies the integration of hyperthermia in the therapeutic armamentarium of clinical management of cancer, especially in low-middle-income group countries.

Abstract
Background
The incidence of cervical cancer is increasing at an alarming rate in many countries and presently, it is the most common form of malignant cancer being reported among women in India. Development of novel approach for cervical cancer therapy, sparing healthy normal cells overcoming the limitations of prevailing therapies is of prime importance. Mangroves constitute a significant repository of medicinally important plants. Thus, in this study, we aimed to determine the anticancer activity of the mangrove Excoecaria agallocha L. leaf extracts on human cervical cancer (SiHa HPV 16+) cell line with subsequent characterization of the bioactive compounds conferring the anticancer activity and studying the probable underlying mechanism of action of the purified plant extract.
Results
The plant extract was subjected to silica gel column chromatography and the fractions obtained were analyzed for cytotoxic activity against SiHa cells by MTT assay. One out of the three eluted fractions exhibited selective toxicity against SiHa cells with an IC50 value of 15.538 ± 0.577 µg/mL, while it had no cytotoxic effect on normal healthy human peripheral blood mononuclear cells. High-resolution liquid chromatography mass spectroscopy, coupled to electron spray ionization and diode array detection analysis, led to the structure elucidation and identification of a few pharmacologically important compounds, with Bergenin being present in the highest abundance. Fluorescence microscopy results revealed that the plant extract fraction induced LC3 puncta formation, in EGFP- SiHa cells indicating the onset of autophagy, with simultaneous stimulation of mitophagy. The plant extract also inhibited proliferation of the SiHa-smac-mCherry cells by second mitochondria-derived activator of caspase (SMAC)—induced cytochrome c dependent apoptosis, that was further confirmed with Caspase-3 activation by colorimetric assay. The GFP-dgn in SiHa cells was remarkably protected from proteasomal degradation that might upregulate the survivability of the cells significantly. Flow cytometry followed by Western blot analysis further asserted the ability of the plant extract fraction to cause cell cycle arrest of SiHa cells in the G2/M phase by significantly reducing protein expression levels of cyclin B1 and D1, decreasing Cdc2 level and simultaneously increasing p21 and p53 levels.
Conclusion
It could be inferred that the aqueous extract of E. agallocha successfully decreased the proliferation of SiHa cervical cancer cells through induction of autophagy and apoptosis in a concerted manner, with simultaneous stimulation of mitophagy and G2/M phase cell cycle arrest, hinting at Bergenin being the major compound conferring the anti-cancer activity of the plant extract. Thus, isolation of the identified bioactive compounds from E. agallocha and their subsequent purification for drug development might serve as a novel medicinal approach for the treatment of cervical cancer in conjugation with existing therapeutic methods.

Abstract
BACKGROUND Concurrent chemoradiotherapy has limited therapeutic efficacy for stage III-IV cervical cancer. We aimed to identify a subgroup of patients with stage III-IV cervical cancer who benefit from concurrent chemoradiotherapy with additional treatment. METHODS We retrospectively reviewed 120 patients with stage III-IV cervical cancer who were treated with concurrent chemoradiotherapy from 2002 to 2018. We compared overall survival between patients treated with concurrent chemoradiotherapy alone and those who received concurrent chemoradiotherapy with additional conventional treatments (systemic chemotherapy before and/or after concurrent chemoradiotherapy and/or extended-field radiation). Prognostic factors were statistically analysed. RESULTS Overall, 44 (36.7%) and 21 (17.5%) patients were radiologically diagnosed with pelvic and para-aortic lymph node enlargement, respectively. The median tumour diameter was 5.7 cm. A total of 69 (57.5%) patients received no additional treatment, and 51 (42.5%) received additional treatment. Cox regression analysis identified the following prognostic factors: histological non-squamous cell carcinoma (hazard ratio, 3.9; 95% confidence interval, 1.8-8.2), tumour diameter of ≥6 cm (hazard ratio, 2.1; 95% confidence interval, 1.2-3.7), radiological pelvic lymph node enlargement (hazard ratio, 2.1; 95% confidence interval, 1.1-4.0) and radiological para-aortic lymph node enlargement (hazard ratio, 2.1; 95% confidence interval, 1.1-4.1). Even in the lowest risk group (no risk factors), the 5-year overall survival rate was lower in the additional treatment group than in the concurrent chemoradiotherapy alone group (78.7% vs. 80.9%, respectively; log-rank test, P = 0.79). CONCLUSIONS Addition of conventional treatments to concurrent chemoradiotherapy might not improve survival in patients with advanced cervical cancer. Novel treatment strategies including immune checkpoint inhibitors should be considered for such patients.

Abstract
BACKGROUND Given the lack of primary and secondary prevention programs and cancer awareness in general, cervical cancer remains one of the main causes of cancer-related death in developing countries, such as Bosnia and Herzegovina. Optimization of combinations of external radiation therapy (ERT), brachytherapy and chemotherapy is still needed to improve outcomes in the treatment of advanced cervical cancer. PATIENTS AND METHODS We retrospectively analyzed 48 consecutive patients with Fédération Internationale de Gynecologie et d'Obstetrique (FIGO) 2009 stage IB2-IVA, who were treated with primary concomitant chemobrachyradiotherapy (CCBRT) and consolidation chemotherapy at the Department of Oncology, University Hospital Mostar, Bosnia and Herzegovina between December 2012 and June 2020. Patients were treated with ERT plus two cycles of concomitant chemobrachytherapy with ifosfamide and cisplatin and low-dose rate (LDR) brachytherapy followed by four cycles of consolidation chemotherapy at 3‑week intervals. We evaluated local control rate (LCR), disease-free survival (DFS), overall survival (OS), disease-specific survival (DSS) and toxicity. RESULTS After 45.5 months (interquartile range, IQR = 47 months) of median follow-up, 5‑year DFS was 72.8% (95% confidence interval. CI 59-78%), OS was 76.6% (95% CI 60-79%), and DSS was 88% (95% CI 71-86%) with acceptable toxicity. LCR was 94%. CONCLUSION Primary CCBRT and consolidation chemotherapy applied in standard clinical practice in the treatment of locally advanced cervical cancer (LACC) produce respectable outcomes.

Added-value of dynamic contrast-enhanced MRI on prediction of tumor recurrence in locally advanced cervical cancer treated with chemoradiotherapy. Eur Radiol 2021; 32:2529-2539.

Abstract
OBJECTIVES To evaluate whether the DCE-MRI derived parameters integrated into clinical and conventional imaging variables may improve the prediction of tumor recurrence for locally advanced cervical cancer (LACC) patients following concurrent chemoradiotherapy (CCRT). METHODS Between March 2014 and November 2019, 79 consecutive LACC patients who underwent pelvic MRI examinations with DCE-MRI sequence before treatment were prospectively enrolled. The primary outcome was disease-free survival (DFS). DCE-MRI derived parameters, conventional imaging, and clinical factors were collected. Univariate and multivariate Cox hazard regression analyses were performed to evaluate these parameters in the prediction of DFS. The independent and prognostic interested variables were combined to build a prediction model compared with the clinical International Federation of Gynecological (FIGO) staging system. RESULTS Lymph node metastasis (LNM) and the mean value of ve (ve_mean) were independently associated with tumor recurrence (all p < 0.05). The prediction model based on T stage, LNM, and ve_mean demonstrated a moderate predictive capability in identifying LACC patients with a high risk of tumor recurrence; the model was more accurate than the FIGO staging system alone (c-index: 0.735 vs. 0.661) and the combination of ve_mean and the FIGO staging system (c-index: 0.735 vs. 0.688). Moreover, patients were grouped into low-, medial-, and high-risk levels based on the advanced T stage, positive LNM, and ve_mean < 0.361, with which the 2-year DFS was significantly stratified (p < 0.001). CONCLUSIONS The ve_mean from DCE-MRI could be used as a useful biomarker to predict DFS in LACC patients treated with CCRT as an assistant of LNM and T stage. KEY POINTS Lower ve_mean is an independent predictor of poor prognosis for disease-free survival in locally advanced cervical cancer patients treated with concurrent chemoradiotherapy (hazard ratio [HR]: 0.016, p<0.023). A combined prediction model based on advanced T stage, LNM, and ve_mean performed better than the FIGO staging system alone.

Abstract
BACKGROUND Cervical cancer is a common malignancy of the female genital tract. Treatment options for cervical cancer patients diagnosed at FIGO (2009) stage IB2 and IIA2 remains controversial. METHODS We perform a Bayesian network meta-analysis to directly or indirectly compare various interventions for FIGO (2009) IB2 and IIA2 disease, in order to improve our understand of the optimal treatment strategy for these women. Three databases were searched for articles published between 1971 and 2020. Data on included study characteristics, outcomes, and risk of bias were abstracted by two reviewers. RESULTS Seven thousand four hundred eighty-six articles were identified. Thirteen randomized controlled trials of FIGO (2009) IB2 and IIA2 cervical cancer patients were included in the final analysis. These trials used six different interventions: concomitant chemoradiotherapy (CCRT), radical surgery (RS), radical surgery following chemoradiotherapy (CCRT+RS), neoadjuvant chemotherapy followed by radical surgery (NACT+RS), adjuvant radiotherapy followed by Radical surgery (RT + RS), radiotherapy alone (RT).SUCRA ranking of OS and Relapse identified CCRT+RS and CCRT as the best interventions, respectively. Systematic clustering analysis identified the CCRT group as a unique cluster. CONCLUSION These data suggest that CCRT may be the best approach for improving the clinical outcome of cervical cancer patients diagnosed at FIGO (2009) stage IB2/IIA2. Phase III randomized trials should be performed in order to robustly assess the relative efficacy of available treatment strategies in this disease context.

Abstract
Cervical cancer is the most common gynecologic malignancy worldwide. Methyltransferase-like 3 (METTL3) is involved in tumorigenesis; however, it is unclear whether METTL3 plays a potential role in regulating cisplatin (DDP) resistance. Therefore, the role of METTL3 in the regulation of cisplatin sensitivity in cervical cancer cells was determined. Our immunohistochemistry (IHC) data showed that METTL3 was highly expressed in para-cancerous compared with cervical cancer tissues. Furthermore, METTL3 overexpression inhibited viability and increased cisplatin sensitivity of cervical cancer cells in vitro. Overexpression of METTL3 inhibited tumor growth in vivo. IHC results showed that the receptor for advanced glycation and products (RAGE) had higher expression levels in cervical cancer tissues. RAGE downregulation increased cell sensitivity to cisplatin treatment. Moreover, the combination of FPS-ZM1 with cisplatin was more effective in inhibiting cell viability as compared with FPS-ZM1 or cisplatin only. Additionally, METTL3 reduced RAGE expression in cervical cancer cells. Overexpression of METTL3 downregulated RAGE expression and caused more sensitivity to cisplatin treatment in the SiHa-DDP cell line. METTL3 inhibited cell viability and increased apoptosis as well as enhanced the sensitivity of cisplatin via downregulating RAGE expression in cervical cancer cells.

Abstract
BACKGROUND Early prediction of response to concurrent chemoradiotherapy (cCRT) could aid to further optimize treatment regimens for locally advanced cervical cancer (LACC) in the future. PURPOSE To explore whether quantitative parameters from baseline (pre-therapy) magnetic resonance imaging (MRI) and FDG-PET/computed tomography (CT) have potential as predictors of early response to cCRT. MATERIAL AND METHODS Forty-six patients with LACC undergoing cCRT after staging with FDG-PET/CT and MRI were retrospectively analyzed. Primary tumor volumes were delineated on FDG-PET/CT, T2-weighted (T2W)-MRI and diffusion-weighted MRI (DWI) to extract the following quantitative parameters: T2W volume; T2W signalmean; DWI volume; ADCmean; ADCSD; MTV42%; and SUVmax. Outcome was the early treatment response, defined as the residual tumor volume on MRI 3-4 weeks after start of external beam radiotherapy with chemotherapy (before the start of brachytherapy): patients with a residual tumor volume <10 cm3 were classified as early responders. Imaging parameters were analyzed together with FIGO stage to assess their performance to predict early response, using multivariable logistic regression analysis with bi-directional variable selection. Leave-one-out cross-validation with bootstrapping was used to simulate performance in a new, independent dataset. RESULTS T2W volume (OR 0.94, P = 0.003) and SUVmax (OR 1.15, P = 0.18) were identified as independent predictors in multivariable analysis, rendering a model with an AUC of 0.82 in the original dataset, and AUC of 0.68 (95% CI 0.41-0.81) from cross-validation. CONCLUSION Although the predictive performance achieved in this small exploratory dataset was limited, these preliminary data suggest that parameters from baseline MRI and FDG-PET/CT (in particular pre-therapy tumor volume) may contribute to prediction of early response to cCRT in cervical cancer.

Abstract
Cervical cancer (CC) is a common malignant tumor of the female reproductive system. This study investigated the role of aplysia ras homolog I (ARHI) in resistance to CC in vitro and in patients' tissues. Hela cells were continuously treated with different concentrations of paclitaxel (1-10 nM) to construct paclitaxel-resistant cell model (Hela-TR). CC or CC-TR tissues were obtained from CC patients or CC patients who had developed paclitaxel resistance. The level of ARHI and multidrug resistance gene 1 (MDR1) in cells and tissues were detected by qRT-PCR and immunohistochemistry (IHC) staining. Cell viability, apoptosis and the number of colonies were assessed by MTT, flow cytometry and cell clone assay in Hela and Hela-TR cells after the ARHI plasmid or shARHI were transfected into cells. The autophagy and apoptosis signaling related proteins were analyzed by western blotting. The results revealed that the levels of ARHI mRNA and protein were down-regulated in CC tissues, and were further reduced in paclitaxel-resistant tissues and Hela cell model. High expression of ARHI inhibited the expression of MDR1 in Hela and Hela-TR cells. The cell viability and cell clone of Hela and Hela-TR cells were decreased by ARHI overexpression but increased by ARHI suppression. In addition, highly expressed ARHI promoted apoptosis and activated autophagy by increasing LC3-II/LC3-I through inactivating AKT/mTOR signaling pathway. In conclusion, overexpression of ARHI can increase the sensitivity of CC to paclitaxel through promoting apoptosis and autophagy in a AKT/mTOR inactivation dependent pathway.
