BIOMOLECULES & BIOMEDICINE 2024; 24:1463-1469. [PMID: 38814195 PMCID: PMC11496866 DOI: 10.17305/bb.2024.10591] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/11/2024] [Revised: 05/27/2024] [Accepted: 05/27/2024] [Indexed: 05/31/2024]
Abstract
The effectiveness of removing lymph nodes before initial treatment in patients with locally advanced cervical cancer is still debated. This article presents a meta-analysis that systematically evaluates the impact of this approach on oncological outcomes. A systematic literature search of PubMed, Embase, Science Direct, and the Cochrane Database of Systematic Reviews (up to December 2023) was performed to obtain relevant studies. The findings were combined using fixed-effects models to address potential differences. Combined risk ratios (HR) and 95% confidence intervals (CI) were calculated. Egger's test was used to assess publication bias. Out of 1025 screened articles, four studies (involving 838 women) met the inclusion criteria. The results showed that lymph node dissection before initial treatment did not affect overall survival (OS) in patients with locally advanced cervical cancer compared to concurrent radiotherapy (HR = 1.11, 95% CI = 0.91-1.36, P = 0.30). It also did not increase the incidence of postoperative complications or cause delays in radiotherapy. In particular, removing larger lymph nodes (>2cm) aided in defining the radiation field and decreasing radiotherapy-related complications. The surgical technique also had some impact on postoperative complications. In summary, in order to obtain the best therapeutic outcomes, personalized plans should be developed for each patient, accounting for their individual circumstances to achieve precise treatment and enhance their quality of life.

Abstract
Purpose PET-CT has recently been included in the NCCN staging recommendations for cervical cancer stages II–IV and is already routinely applied to radiotherapy planning for other malignancies, as it is expected to provide higher accuracy for the detection of areas with tumor cell spread. In this study, we report on our first experiences of PET-based radiotherapy planning for cervical cancer. Methods 19 patients with cervical cancer that underwent pre-therapeutic PET imaging treated at our institution between January 2016 and April 2019 were included in the study. Information on the primary tumor, lymph node involvement, metastatic spread and changes in the radiotherapy procedure based on the PET findings are described. Results A previously unknown primary tumor extension that was detected by PET imaging in one patient. In patients who underwent a PET before the systematic pelvic and paraaortic lymphonodectomy (n = 2), PET was false negative for pelvic lymph node metastases in 50%. In patients who underwent a PET after the systematic LNE (n = 13), additional lymph node metastases were detected in seven patients (53.80%). Distant metastases were suspected in three patients (15.7%) based on PET imaging. The suspicion was confirmed in one patient (peritoneal spread) and excluded in two patients (supra-diaphragmatic lymph nodes). In 13 patients (68.4%), RT procedures were altered due to findings in PET imaging. Conclusion PET-based radiochemotherapy planning may improve control rates by identifying areas of tumor cell spread eligible for dose escalation. False positivity, however, should be excluded in patients with findings that lead to major modifications of the therapeutic strategy.

Eur J Obstet Gynecol Reprod Biol 2021; 264:36-40. [PMID: 34273752 DOI: 10.1016/j.ejogrb.2021.06.046] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2021] [Revised: 05/06/2021] [Accepted: 06/27/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVE In women with cervical cancer (CC), treatment with radiation causes changes in vaginal biomechanical properties, anatomy and function. The aims of the current study were to objectively assess effects of radiotherapy (RT) on vaginal elasticity, wall mobility and contraction strength; and to evaluate associations of these changes with sexual function. STUDY DESIGN This prospective cohort study was approved by our Institutional Review Board. Between May 2018 and June 2020, women with CC who were candidates for RT were eligible to participate. Participants underwent vaginal tactile imaging (VTI) evaluation and were asked to fill the Female Sexual Function Index (FSFI) questionnaire at the time of first RT session and at a 6-month post-treatment follow up visit. Women who underwent radical hysterectomy, or had pelvic side-wall, pelvic or distant organ metastasis were not included. RESULTS A total of 25 women with locally advanced CC were included in the final analysis. The mean age was 39 ± 2.7 years, the mean BMI was 24.8 ± 2.2 kg/m2 and the median parity was 2 (range: 1-5). Following RT, the mean scores for vaginal elasticity and vaginal tightening were significantly lower than at pre-treatment: 11.3 ± 2.5 vs. 28.3 ± 9, P < 0.0001 and 2.6 ± 0.7 vs. 16.7 ± 3, P < 0.0001, respectively. Following RT, significant decreases were demonstrated in vaginal wall mobility and pelvic muscle contraction strength: from 1.77 ± 0.34 to 0.36 ± 0.15, P < 0.0001 and from 2.55 ± 0.48 to 0.52 ± 0.23, P < 0.0001, respectively. Compared to pre-treatment, post-RT vaginal length was significantly shorter (3.30 ± 0.22 vs. 7.64 ± 0.63, P = 0.0023) and sexual intercourse frequency significantly lower: 1 (range 1-2) vs. 2 (range 1-4), P = 0.014). The mean total FSFI score was significantly lower following RT (6.7 ± 1 vs. 14.5 ± 2.7, P < 0.0001). CONCLUSIONS Women with locally advanced CC who have been treated with RT exhibit persistent vaginal biomechanical changes that compromise sexual activity and result in considerable distress.

Current Updates on Cancer-Causing Types of Human Papillomaviruses (HPVs) in East, Southeast, and South Asia. Cancers (Basel) 2021; 13:cancers13112691. [PMID: 34070706 PMCID: PMC8198295 DOI: 10.3390/cancers13112691] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 05/23/2021] [Accepted: 05/25/2021] [Indexed: 12/13/2022] Open
Abstract
Simple Summary Among the over 200 human papillomavirus (HPV) genotypes identified, approximately 15 of them can cause human cancers. In this review, we provided an updated overview of the distribution of cancer-causing HPV genotypes by countries in East, Southeast and South Asia. Besides the standard screening and treatment methods employed in these regions, we unravel HPV detection methods and therapeutics utilised in certain countries that differ from other part of the world. The discrepancies may be partly due to health infrastructure, socio-economy and cultural diversities. Additionally, we highlighted the area lack of study, particularly on the oncogenicity of HPV genotype variants of high prevalence in these regions. Abstract Human papillomavirus (HPV) infection remains one of the most prominent cancer-causing DNA viruses, contributing to approximately 5% of human cancers. While association between HPV and cervical cancers has been well-established, evidence on the attribution of head and neck cancers (HNC) to HPV have been increasing in recent years. Among the cancer-causing HPV genotypes, HPV16 and 18 remain the major contributors to cancers across the globe. Nonetheless, the distribution of HPV genotypes in ethnically, geographically, and socio-economically diverse East, Southeast, and South Asia may differ from other parts of the world. In this review, we garner and provide updated insight into various aspects of HPV reported in recent years (2015–2021) in these regions. We included: (i) the HPV genotypes detected in normal cancers of the uterine cervix and head and neck, as well as the distribution of the HPV genotypes by geography and age groups; (ii) the laboratory diagnostic methods and treatment regimens used within these regions; and (iii) the oncogenic properties of HPV prototypes and their variants contributing to carcinogenesis. More importantly, we also unveil the similarities and discrepancies between these aspects, the areas lacking study, and the challenges faced in HPV studies.

Abstract
PURPOSE To evaluate the treatment related acute and delayed toxicities of extended field Volumetric modulated arc therapy (VMAT) with concurrent chemotherapy in patients of locally advanced cervical cancer with pelvic lymph nodes. MATERIAL AND METHODS From 2014 to 2016, 15 patients of locally advanced cervical cancer with Fluoro-deoxyglucose positron emission tomography (FDG-PET) positive pelvic lymph nodes were treated with extended field Simultaneous integrated boost (SIB)-VMAT 45 Gy/55 Gy/25#/5weeks and concurrent cisplatin. Acute toxicities were documented according to common terminology criteria for adverse events version 4 (CTCAE v.4). Dose volume parameters and patient characteristics were analyzed for association with toxicities. RESULTS Median age of patients at diagnosis was 48 years. 40% (6 patients) were stage IIB & 60% (9 patients) were stage IIIB. Median number of involved pelvic lymph nodes was 2 (range, 1-4), commonest location was external iliac lymph node region (86%). Median number of concurrent chemotherapy cycles received was five. Treatment was well tolerated and there were no grade ≥ 3 acute toxicities. Commonest acute toxicities observed were vomiting (≥grade2 -13.3%) followed by & nausea (grade ≥ 2 in 6%) and were associated with volume of bowel bag receiving 45 Gy. Constitutional symptoms (≥grade 2) were observed in 6% patients and had no dosimetric associations. At a median follow up of 43 months, delayed ≥ grade1, 2, 3 toxicity were observed in 80%, 0%, and 0% respectively with diarrhea being the commonest. CONCLUSION Prophylactic para aortic extended field VMAT with concurrent chemotherapy for locally advanced cervical cancer is well tolerated with acceptable acute toxicity profile. Significant grade 3 acute/delayed toxicities were not observed in this cohort of patients.

Abstract
BACKGROUND Cervical squamous cell carcinoma (CSCC) is the most common histological subtype of cervical cancer. The purpose of this study was to assess prognostic factors and establish personalized risk assessment nomograms to predict overall survival (OS) and cancer-specific survival (CSS) in CSCC patients. METHODS CSCC patients diagnosed between 1988 and 2015 were identified in the Surveillance, Epidemiology, and End Results (SEER) database. Univariate and multivariate Cox proportional hazard regression models were applied to select meaningful independent predictors and construct predictive nomogram models for OS and CSS. The concordance index (C-index), calibration curve, and receiver operating characteristic (ROC) curve were used to determine the predictive accuracy and discriminability of the nomogram. RESULTS A total cohort (n=17962) was randomly divided into a training cohort (n=11974) and a validation cohort (n=5988). Age, race, histologic grade, clinical stage, tumor size, chemotherapy and historic stage were assessed as common independent predictors of OS and CSS. The C-index value of the nomograms for predicting OS and CSS was 0.771 (95% confidence interval 0.762-0.780) and 0.786 (95% confidence interval 0.777-0.795), respectively. Calibration curves of the nomograms indicated satisfactory consistency between nomogram prediction and actual survival for both 3-year and 5-year OS and CSS. CONCLUSION We constructed nomograms that could predict 3- and 5-year OS and CSS of CSCC patients. These nomograms showed good performance in prognostic prediction and can be used as an effective tool to evaluate the prognosis of CSCC patients, thus contributing to clinical decision making and individualized treatment planning.

Abstract
Surgery, including minimally invasive surgery, and radiotherapy are key modalities in the treatment of gynecological malignancies. The aim of this review is to offer the multidisciplinary care team a comprehensive summary of the intersections of surgery and radiotherapy in the local treatment of gynecological malignancies. Recent advances in radiotherapy are highlighted. Relevant publications were identified through a review of the published literature. Ovarian, endometrial, cervical, vaginal, and vulvar cancer were included in the search. Current guidelines are summarized. The role of radiotherapy in adjuvant as well as definitive treatment of these entities is synthesized and put into context with surgery, focusing on survival and quality of life. Although these outcomes have improved recently, further research must be focused on the number of life years lost, and the potential morbidity encountered by patients.

Abstract
Currently, the standard radiation field for locally advanced cervical cancer patients without evidence of para-aortic lymph node (PALN) metastasis is the pelvis. Due to the low accuracy of imaging in the diagnosis of PALN metastasis and the high incidence of PALN failure after pelvic radiotherapy, prophylactic pelvic and para-aortic irradiation, also called extended-field irradiation (EFI), is performed for patients with cervical cancer. In the era of concurrent chemoradiotherapy, randomized controlled trials are limited, and whether patients with cervical cancer can benefit from prophylactic EFI is still controversial. With conformal or intensity-modulated radiation therapy, patients tolerate prophylactic EFI very well. The severe toxicities of prophylactic EFI are not significantly higher than those of pelvic radiotherapy. We recommend delivering prophylactic EFI to cervical cancer patients with common iliac lymph nodes metastasis. Clinical trials are needed to investigate whether patients with ≥3 positive pelvic lymph nodes and FIGO stage IIIB disease can benefit from prophylactic EFI. According to the distribution of PALNs, it is reasonable to use the renal vein as the upper border of the radiation therapy field for patients treated with prophylactic EFI. The clinical target volume expansion of the node from the vessel should be smaller in the right para-caval region than in the left lateral para-aortic region. The right para-caval region above L2 or L3 may be omitted from the PALN target volume to reduce the dose to the duodenum. More clinical trials on prophylactic EFI in cervical cancer are needed.

Abstract
PURPOSE To assess the impact of laparoscopic extraperitoneal paraaortic staging in therapeutic planning and prognosis of patients with locally advanced cervical cancer (LACC) as compared with imaging staging. METHODS Retrospective multicenter study of stage IB2 and IIA2 to IVA (FIGO 2009) LACC patients who were candidates for primary chemoradiotherapy. The study (surgical) group included 634 patients undergoing laparoscopic/robotic extraperitoneal paraaortic staging treated with extended-field radiotherapy (EFRT) if lymph node involvement was confirmed. The control (imaging) group included 288 patients treated with EFRT when lymph node involvement was suspected on positron emission tomography-computed tomography scans and/or magnetic resonance imaging. RESULTS In the study group, a median of 13 (range 9-17) lymph nodes were removed, with a rate of positive paraaortic nodes of 18%, with metastatic size ≤ 5 mm in 20.4% of cases. Paraaortic EFRT was administered to 18% of patients in the study group and in 58% of controls. In 34% of patients from the surgical group, EFRT was modified according to surgical findings with respect to imaging staging. The median follow-up in the study and control groups was 3.7 and 4.8 years, respectively. In both groups, the overall survival and cancer-specific disease-free survival were similar. The time interval between diagnosis and starting EFRT was 18 days longer in the study group, without differences in overall survival as compared with controls (hazard ratio 1.00, 95% confidence interval 0.998-1.005; p = 0.307). CONCLUSIONS Laparoscopic extraperitoneal paraaortic staging in LACC patients is safe and modified therapeutic planning, allowing better selection of candidates for EFRT.

Background The new staging system of cervical cancer issued in 2018 by the International Federation of Gynecology and Obstetrics (FIGO), calls for a new evaluation of the efficacy of prophylactic extended field irradiation (EFI) in the concomitant chemoradiotherapy/brachytherapy treatment of locally advanced cervical cancer patients (stage IIIB). Methods We performed a retrospective study consisting of 133 FIGO IIIB cervical cancer patients treated in the Peking Union Medical College Hospital from 2002 to 2010. The patients were distributed in two groups depending whether they were treated with EFI or pelvic only irradiation. The therapeutic efficacy, toxicity and prognostic factors of EFI were evaluated in the frame of the new FIGO staging system. Results When compared to patients who received pelvic only irradiation, patients who received prophylactic EFI showed significantly less distant metastasis and a significant improvement in their 5 years overall survival (OS), disease free survival (DFS), out of field recurrence free survival (OFRFS) and para-aortic lymph node metastasis free survival (PALNMFS). Multivariate analysis revealed that EFI is an independent prognosis factor for DFS, OFRFS and PALNMFS. Finally, although more acute complications were observed in the EFI group, there is no significantly worst acute toxicity in the EFI group. Conclusion Our retrospective analysis supports the prophylactic effect of EFI in the concomitant chemoradiotherapy treatment of IIIB patients and suggests that this prophylactic effect is associated with a clear improvement in 5-years OS, DFS, OFRFS and PALNMFS. Consequently, EFI appears to be a very valid treatment option for FIGO IIIB cervical cancer patients.

Abstract
BACKGROUND The para-aortic lymph nodes (located along the major vessels in the mid and upper abdomen) are a common place for disease recurrence after treatment for locally advanced cervical cancer. The para-aortic area is not covered by standard pelvic radiotherapy fields and so treatment to the pelvis alone is inadequate for women at a high risk of occult cancer within para-aortic lymph nodes. Extended-field radiotherapy (RT) widens the pelvic RT field to include the para-aortic lymph node area. Extended-field RT may improve outcomes in women with locally advanced cervical cancer by treating occult disease in para-aortic nodes not identified at pretreatment imaging. However, RT treatment of the para-aortic area can cause severe adverse effects, so may increase harms.Studies of pelvic chemoradiotherapy (CRT) demonstrated improved survival rates compared to pelvic RT alone. CRT is now the standard of care in the treatment of locally advanced cervical cancer. Studies comparing pelvic RT alone (without concurrent chemotherapy) with extended-field RT should therefore be viewed with caution, since they compare treatments against what is now substandard treatment (pelvic RT alone). This review should therefore be read with this in mind and comparisons with pelvic RT cannot be extrapolated to pelvic CRT. OBJECTIVES To evaluate the effectiveness and toxicity of extended-field radiotherapy in women undergoing first-line treatment for locally advanced cervical cancer. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 7), MEDLINE via Ovid (1946 to August week 4, 2018), and Embase via Ovid (1980 to 2018, week 35). We checked registers of clinical trials, grey literature, conference reports, and citation lists of included studies to August 2018. SELECTION CRITERIA We included randomised controlled trials (RCTs) evaluating the effectiveness and toxicity of extended-field RT for locally advanced cervical cancer. DATA COLLECTION AND ANALYSIS Two review authors independently selected potentially relevant RCTs, extracted data, assessed risk of bias, compared results, and made judgements on the quality and certainty of the evidence for each outcome. Any disagreements were resolved by discussion or consultation with a third review author. MAIN RESULTS Five studies met the inclusion criteria. Three included studies compared extended-field RT versus pelvic RT, one included study compared extended-field RT with pelvic CRT, and one study compared extended-field CRT versus pelvic CRT.Extended-field radiotherapy versus pelvic radiotherapy aloneCompared to pelvic RT, extended-field RT probably reduces the risk of death (hazard ratio (HR) 0.67, 95% confidence interval (CI) 0.48 to 0.94; 1 study; 337 participants; moderate-certainty evidence) and para-aortic lymph node recurrence (risk ratio (RR) 0.36, 95% CI 0.18 to 0.70; 2 studies; 477 participants; moderate-certainty evidence), although there may or may not have been improvement in the risk of disease progression (HR 0.92, 95% CI 0.69 to 1.22; 1 study; 337 participants; moderate-certainty evidence) and severe adverse events (RR 1.05, 95% CI 0.79 to 1.41; 2 studies; 776 participants; moderate-certainty evidence).Extended-field radiotherapy versus pelvic chemoradiotherapyIn a comparison of extended-field RT versus pelvic CRT, women given pelvic CRT probably had a lower risk of death (HR 0.50, 95% CI 0.39 to 0.64; 1 study; 389 participants; moderate-certainty evidence) and disease progression (HR 0.52, 95% CI 0.37 to 0.72; 1 study; 389 participants; moderate-certainty evidence). Participants given extended-field RT may or may not have had a lower risk of para-aortic lymph node recurrence (HR 0.44, 95% CI 0.20 to 0.99; 1 study; 389 participants; low-certainty evidence) and acute severe adverse events (RR 0.05, 95% CI 0.02 to 0.11; 1 study; 388 participants; moderate-certainty evidence). There were no clear differences in terms of late severe adverse events among the comparison groups (RR 1.06, 95% CI 0.69 to 1.62; 1 study; 386 participants; moderate-certainty evidence).Extended-field chemoradiotherapy versus pelvic chemoradiotherapyVery low-certainty evidence obtained from one small study (74 participants) showed that, compared to pelvic CRT, extended-field CRT may or may not have reduced risk of death (HR 0.37, 95% CI 0.14 to 0.96) and disease progression (HR 0.25, 95% CI 0.07 to 0.87). There were no clear differences between the groups in the risks of para-aortic lymph node recurrence (RR 0.19, 95% CI 0.02 to 1.54; very low-certainty evidence) and severe adverse events (acute: RR 0.95, 95% CI 0.20 to 4.39; late: RR 0.95, 95% CI 0.06 to 14.59; very low-certainty evidence). AUTHORS' CONCLUSIONS Moderate-certainty evidence shows that, compared with pelvic RT alone, extended-field RT probably improves overall survival and reduces risk of para-aortic lymph node recurrence. However, pelvic RT alone would now be considered substandard treatment, so this result cannot be extrapolated to modern standards of care. Low- to moderate-certainty evidence suggests that pelvic CRT may increase overall and progression-free survival compared to extended-field RT, although there may or may not be a higher rate of para-aortic recurrence and acute adverse events. Extended-field CRT versus pelvic CRT may improve overall or progression-free survival, but these findings should be interpreted with caution due to very low-certainty evidence.High-quality RCTs, comparing modern treatment techniques in CRT, are needed to more fully inform treatment for locally advanced cervical cancer without obvious para-aortic node involvement.
