Abstract
Since the National Cancer Institute (NCI) alert of concurrent chemoradiotherapy, radiotherapy has been changed from external beam radiotherapy plus brachytherapy to platinum-based concurrent chemoradiotherapy. Therefore, concurrent chemoradiotherapy plus brachytherapy has become a standard treatment for locally advanced cervical cancer. Simultaneously, definitive radiotherapy has been changed gradually from external beam radiotherapy plus low-dose-rate intracavitary brachytherapy to external beam radiotherapy plus high-dose-rate intracavitary brachytherapy. Cervix cancer is uncommon in developed countries; hence, international collaborations have been critical in large-scale clinical trials. The Cervical Cancer Research Network (CCRN), created from the Gynecologic Cancer InterGroup (GCIG), has investigated various concurrent chemotherapy regimens and sequential methods of radiation and chemotherapy. Most recently, many clinical trials of combining immune checkpoint inhibitors with radiotherapy have been ongoing for sequential or concurrent settings. During the last decade, the method of standard radiation therapy has changed from three-dimensional conformal radiation therapy to intensity-modulated radiation therapy for external beam radiotherapy and from two-dimensional to three-dimensional image-guided approaches for brachytherapy. Recent improvements include stereotactic ablative body radiotherapy and MRI-guided linear accelerator (MRI-LINAC) using adaptive radiotherapy. Here we review the current progress of radiation therapy during the last two decades.

Abstract
Background Since the GOG125 study, treating radically patients with positive para-aortic lymph nodes has been a valid approach. Nevertheless, literature lacks data on how to better treat these patients since they are usually excluded from trials. In this study, we aimed to report the outcomes of patients with advanced cervical cancer and positive para-aortic lymph nodes (PAN) treated in a single tertiary/academic institution and try to identify variables that may impact survival. Materials and methods We retrospectively reviewed patients with positive para-aortic lymph nodes treated in our institution. Demographic variables and treatment options were assessed and their impact on overall survival (OS), locorregional control, distant metastasis free survival, and para-aortic lymph node progression was analyzed. Results We assessed 65 patients treated from April 2010 to May 2017. Median OS was 38.7 months. Median locorregional and para-aortic progression free survivals were not reached. Median distant metastasis progression-free survival was 64.3 months. Better ECOG performance status (p > 0.001), concurrent chemotherapy (p = 0.031), and brachytherapy (p = 0.02) were independently related to better overall survival. Conclusion Patients with current stage IIIC2 cervix cancer may present long term survival. Treating positive PAN cervical cancer patients with concurrent chemoradiation including brachytherapy with curative intent should be standard. Poor PS and more advanced pelvic disease may represent a higher risk for worse outcomes. Distant metastases are still a challenge for disease control.

Abstract
Cervical cancer is the fourth most common malignant tumor globally in terms of morbidity and mortality. The presence of lymph node metastasis (LNM) is an independent prognostic factor for progression-free survival (PFS) and overall survival (OS) in cervical cancer patients. The International Federation of Gynecology and Obstetrics (FIGO) staging system was revised in 2018. An important revision designates patients with regional LNM as stage IIIC, pelvic LNM only as stage IIIC1, and para-aortic LNM as stage IIIC2. However, the current staging system is only based on the anatomical location of metastatic lymph nodes (LNs). It does not consider other LN status parameters, which may limit its prognostic significance to a certain extent and needs further exploration and confirmation in the future. The purpose of this review is to summarize the choice of treatment for stage IIIC cervical cancer and the effect of different LN status parameters on prognosis.

Abstract
Locally advanced cervical cancer with the involvement of para-aortic lymph nodes (PALN) is a common occurrence in low-income and low-middle-income countries. With the incorporation of PALN in the recent FIGO staging, therapeutic management becomes crucial. There are varied presentations of this group which may range from microscopic involvement to extensive lymphadenopathy. Various imaging modalities have been studied to accurately diagnose PALN metastases without surgical intervention, while some investigators have studied the survival benefit of para-aortic lymph node dissection for accurate staging and guiding extent of radiation. With recent advances in radiation therapy, its application to treat bulky nodal metastases and the role of prophylactic irradiation have been reported. In this review, the available evidence and the scope of further interventions is presented.

Adjuvant Systemic Therapy after Chemoradiation and Brachytherapy for Locally Advanced Cervical Cancer: A Systematic Review and Meta-Analysis. Cancers (Basel) 2021; 13:1880.

Abstract
BACKGROUND Standard of care for locally advanced cervical cancer is chemoradiation and brachytherapy. The addition of adjuvant systemic treatment may improve overall survival. A systematic review and meta-analysis was conducted to summarize evidence on survival outcomes, treatment completion and toxicity. METHODS PubMed, EMBASE and Web of Science were systematically searched for relevant prospective and retrospective studies. Two authors independently selected studies, extracted data and assessed study quality. Pooled hazard ratios for survival endpoints were estimated using random effect models. Weighted averages of treatment completion and toxicity rates were calculated and compared by the Fisher exact test. RESULTS The search returned 612 articles; 35 articles reporting on 29 different studies on adjuvant chemotherapy or immunotherapy were selected for systematic review. Twelve studies on an adjuvant platinum-pyrimidine antagonist or platinum-taxane were included for meta-analysis. The pooled hazard ratios for overall survival were 0.76 (99%CI: 0.43-1.34, p = 0.22) and 0.47 (99%CI: 0.12-1.86, p = 0.16) for the addition of, respectively, a platinum-pyrimidine antagonist or platinum-taxane to chemoradiation and brachytherapy. Completion rates were 82% (95%CI: 76-87%) for platinum-pyrimidine antagonist and 74% (95%CI: 63-85%) for platinum-taxane. Severe acute hematological and gastro-intestinal toxicities were significantly increased by adding adjuvant chemotherapy to chemoradiation and brachytherapy. CONCLUSIONS The addition of adjuvant platinum-pyrimidine antagonist or platinum-taxane after chemoradiation and brachytherapy does not significantly improve overall survival, while acute toxicity is significantly increased. These adjuvant treatment strategies can therefore not be recommended for unselected patients with locally advanced cervical cancer.

Abstract
The clinical, molecular, and genetic heterogeneity of uterine cervix cancers makes the discovery of effective therapies a challenge. Optimal evaluation of effective radiotherapy-agent combinations requires sophisticated trial strategies from the United States National Cancer Institute and its pharmaceutical collaborators. One strategy involves the phase 0 trial, which falls under the United States Food and Drug Administration Exploratory Investigational New Drug Guidance, or xIND. As currently envisioned for radiotherapy-based trials, the phase 0 trial provides a platform for study of pharmacodynamic effects linked to pharmacokinetic exposures, designed to screen a new experimental agent's dose or schedule, in combination with standard radiotherapy regimens, in a very small number (10-15) of subjects. In the phase 0 trial, radiotherapy-agent combinations are intended to be biologically active, but a new experimental agent's low dose or infrequent schedule is considered nontoxic and nonbeneficial. The phase 0 trial primary endpoint is an individual subject's pharmacodynamic response. Regimens move on from phase 0 trial development if and when a predetermined all-subject pharmacodynamic response rate is crossed. An initial safety experience during and after the radiotherapy-agent combination determines future feasibility. For this article, the clinical example of women with abdominopelvic lymph node-positive uterine cervix cancer is used to elaborate the phase 0 trial approach to the discovery of novel radiosensitizing oncological agents. It is expected that phase 0 radiotherapy-agent trials will become more prevalent in near-term clinical development.

Abstract
Dihydroartemisinin (DHA) is a potent anti-cancer drug that has limited clinical applications due to poor water solubility and low bioavailability. We designed a biodegradable poly(ethylene glycol) methyl ether-poly(ε-caprolactone) (MPEG-PCL) micelle carrier for DHA using the self-assembly method. The DHA/MPEG-PCL nanoparticles were spherical with an average particle size of 30.28 ± 0.27 nm, and released the drug in a sustained manner in aqueous solution. The drug-loaded nanoparticles showed dose-dependent toxicity in HeLa cells by inducing cycle arrest and apoptosis. Furthermore, compared to free DHA, the DHA/MPEG-PCL nanoparticles showed higher therapeutic efficacy and lower toxicity in vivo, and significantly inhibited tumor growth and prolonged the survival of tumor-bearing nude mice. In addition, the tumor tissues of the DHA/MPEG-PCL-treated mice showed a marked decline in the in situ expression of proliferation and angiogenesis markers. Taken together, the self-assembled DHA/MPEG-PCL nanoparticles are a highly promising delivery system for targeted cancer treatment.

Abstract
OBJECTIVES It is important to develop effective therapies in minorities to ensure equity in cancer care. Underrepresentation of minorities in early phase trials may cause therapies that are effective only in majority populations. We evaluated minority participation in gynecologic oncology phase 1 clinical trials. METHODS In peer-reviewed published articles of gynecologic oncology phase 1 clinical trials from years 1985 to 2018, we manually abstracted racial distribution of enrolled participants, cancer type, and year published. We calculated expected and observed ratios of racial participation on the basis of age-adjusted cancer incidence for race from the United States Centers for Disease Control and Prevention. RESULTS We identified 357 articles of phase 1 trials (total, 9492 participants), including 213 articles on ovarian cancer (60%). Racial distribution of participants was available in 84 articles (23%) that included 2483 participants (26%): 1950 white (79%), 140 black (5%), and 393 other participants (16%). Other nonwhite races exceeded black enrollment in 46 of 84 trials (55%) that listed race. Enrollment of black participants was less than expected from disease incidence for ovarian (incidence-to-enrollment ratio, 18.5; P < .001), endometrial (3.6; P < .001), and cervical cancer (6.8; P < .001). No phase 1 study met expected enrollment for black participants. Frequency of black participants decreased 1.8-fold from 1995 to 1999 (8 of 70 participants [11%]) to 2015-2018 (55 of 892 participants [6%]; P < .025). CONCLUSIONS Major racial underrepresentation exists in gynecologic oncology phase 1 clinical trials. Enrollment of more black participants is needed to achieve racial equity.

Abstract
PURPOSE Cervical cancer is a recalcitrant disease. To help overcome this problem, we previously established a patient-derived orthotopic xenograft (PDOX) model of cervical cancer. In the previous study, we found the tumor to be resistant to nab-paclitaxal (nab-PTX). We also previously developed the tumor-targeting bacteria Salmonella typhimurium A1-R (S. typhimurium A1-R). The aim of the present study was to investigate the efficacy of S. typhimurium A1-R to overcome nab-PTX resistance in the cervical cancer PDOX model. METHODS Cervical-cancer tumor fragments were implanted orthotopically into the neck of the uterus of nude mice. The cervical-cancer PDOX models were randomized into the following four groups after the tumor volume reached 60 mm3: G1: untreated group; G2: nab-PTX (i.v., 10 mg/kg, biweekly, 3 weeks); G3: Salmonella typhimurium A1-R (i.v., 5 × 107 CFU/body, weekly, 3 weeks); G4: nab-PTX combined with Salmonella typhimurium A1-R (nab-PTX, 10 mg/kg, i.v., biweekly, 3 weeks; S. typhimurium A1-R, 5 × 107 CFU/body, i.v., weekly, 3 weeks). Each group comprised eight mice. All mice were sacrificed on day 22. Tumor volume was measured on day 0 and day 22. Body weight was measured twice a week. RESULTS Nab-PTX and Salmonella typhimurium A1-R did not show significant efficacy as monotherapy compared to the control group (P = 0.564 and P = 0.120, respectively). In contrast, nab-PTX combined with Salmonella typhimurium A1-R significantly suppressed tumor growth compared to the untreated control group and nab-PTX group (P < 0.001 and P = 0.026, respectively). CONCLUSIONS Salmonella typhimurium A1-R has potential future clinical application to overcome drug resistance in cervical cancer.

Abstract
OBJECTIVE Tumor volume and regression after external beam radiotherapy have been shown to be accurate parameters to assess treatment response via magnetic resonance imaging (MRI). The aim of the study was to evaluate the prognostic value of tumor size reduction rate after external beam radiotherapy and chemotherapy prior to brachytherapy. METHODS Patients with locally advanced cervical cancer treated at two French comprehensive cancer centers between 1998 and 2010 were included. Treatment was pelvic external beam radiotherapy with platinum based chemotherapy followed by brachytherapy. Records were reviewed for demographic, clinical, imaging, treatment, and follow-up data. Anonymized linked data were used to ascertain the association between pre-external and post-external beam radiotherapy MRI results, and survival data. RESULTS 185 patients were included in the study. Median age at diagnosis was 45 years (range 26-72). 77 patients (41.6%) were International Federation of Gynecology and Obstetrics stage IB2-IIA disease and 108 patients (58.4%) were stage IIB-IVA. Median tumor size after external beam radiotherapy and chemotherapy was 2.0 cm (range 0.0-8.0) and median tumor size reduction rate was 62.4% (range 0.0-100.0%). Tumor size and tumor reduction rate at 45 Gy external beam radiotherapy MRI were significantly associated with local recurrence free survival (P<0.001), disease free survival, and overall survival (P<0.05). Tumor reduction rate ≥60% was significantly associated with a decreased risk of relapse and death (HR (95% CI) 0.21 (0.09 to 0.50), P=0.001 for local recurrence free survival; 0.48 (0.30 to 0.77) P=0.002 for disease free survival; and 0.51 (0.29 to 0.88), P=0.014 for overall survival). CONCLUSIONS Tumor size reduction rate >60% between pre-therapeutic and post-therapeutic 45 Gy external beam radiotherapy with concurrent chemotherapy was associated with improved survival. Future studies may help to identify patients who may ultimately benefit from completion surgery, adjuvant chemotherapy, and closer follow-up.
