Clinical analysis of prophylactic para-aortic intensity-modulated radiation in cervical cancer. Clin Radiol 2023; 78:e77-e84. [PMID: 36195500 DOI: 10.1016/j.crad.2022.08.137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 08/19/2022] [Accepted: 08/22/2022] [Indexed: 01/18/2023]
Abstract
AIM This study aimed to compare the survival and toxicity of patients with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IB1-IIIC cervical cancer without common iliac node metastasis treated with extended-field intensity-modulated radiotherapy (EF-IMRT) or pelvic IMRT (P-IMRT). MATERIALS AND METHODS Thirty-one patients treated with EF-IMRT and 37 patients who underwent P-IMRT were analysed retrospectively. Both groups were treated with high-dose-rate 192Ir two-dimensional brachytherapy and concurrent chemotherapy. The chi-square test and Kaplan-Meier method were used to compare toxicity and survival between the two groups. RESULTS The median follow-up time of EF-IMRT group and P-IMRT group was 22 and 30 months, respectively. The 3-year overall survival (OS), progression-free survival (PFS), and para-aortic lymph node metastasis-free survival (PAMFS) in the EF-IMRT group and P-IMRT group were 87% versus 74.6%, 83.6% versus 61.7%, and 96% versus 80.5%, respectively. Treatment regimens, tumour size, and radiation time were independent prognostic factors of OS and PFS. Treatment regimens, tumour size, and total equivalent dose in 2 Gy/f (EQD2) of point A were independent prognostic factors of PAMFS. Five patients in the EF-IMRT group and 14 patients in P-IMET group experienced treatment failure. The cumulative incidence of grade 3 and 4 acute leukopenia in the EF-IMRT group was 51.6%, in comparison with 27.03% in the pelvic group. No difference was found in thrombocytopenia between two groups. CONCLUSIONS Patients with FIGO 2009 stage IB1-IIIC cervical cancer without common iliac node metastases may be benefit from EF-IMRT. Notably, EF-IMRT exhibits increased toxicity incidence; however, this remains within an acceptable range.

The impact of para-aortic lymph node irradiation on disease-free survival in patients with cervical cancer: a systematic review and meta-analysis. Clin Transl Radiat Oncol 2022; 35:97-103. [PMID: 35669003 PMCID: PMC9166370 DOI: 10.1016/j.ctro.2022.05.006] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 05/24/2022] [Accepted: 05/27/2022] [Indexed: 11/28/2022] Open
Abstract
Standard of care of locally advanced cervical cancer is based on concurrent chemoradiotherapy. Para-aortic radiotherapy (PAO-RT) has become controversial in the chemotherapy era. Systematic review on impact of PAO-RT on disease-free survival yielded 11 studies. Meta-analysis of 3 studies showed pooled adjusted HR of 0.87 (95% CI: 0.79–0.97). Findings support further investigation in prospective controlled trials.
Background Patients with locally advanced cervical cancer without para-aortic lymph node metastases (PAO-LNM) at diagnosis who undergo concurrent chemoradiotherapy are at 4–11% risk of developing PAO-LNM during follow-up. Some studies suggest a beneficial influence of elective para-aortic radiotherapy (PAO-RT) on disease-free survival (DFS) in these patients. The aim of this study was to systematically review and meta-analyse literature on the impact of PAO-RT on DFS in cervical cancer patients. Methods A systematic search of PubMed/MEDLINE and EMBASE databases was performed. The analysis included intervention studies that reported on DFS in patients with cervical cancer who received chemotherapy and pelvic radiotherapy with or without PAO-RT. From each included study, relevant study characteristics and outcome data including the hazard ratio (HR) adjusted for potential confounders were extracted. An overall pooled adjusted hazard ratio (aHR) for DFS after PAO-RT versus no PAO-RT was calculated using a random-effects model. Results A total of 2,016 articles were evaluated. Eleven articles were included in the systematic review, of which 3 were appropriate for quantitative meta-analysis. Pooling of these 3 cohorts (including 1,113 patients) demonstrated a statistically significant association between PAO-RT and DFS (pooled aHR 0.87, 95% confidence interval: 0.79–0.97). No significant heterogeneity among reported aHRs was observed (I2 = 0.0%). Conclusions This meta-analysis suggests a modest but significant beneficial impact of elective para-aortic radiotherapy on DFS in patients with locally advanced cervical cancer who undergo concurrent chemoradiotherapy. This finding based on non-randomized studies provides an imperative for further investigation in prospective controlled trials.

[PMID: 35410240 PMCID: PMC9003999 DOI: 10.1186/s12905-021-01588-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Accepted: 12/29/2021] [Indexed: 11/18/2022] Open
Abstract
Background Cervical adenosquamous carcinoma (ASC) was previously thought to be a subtype of cervical adenocarcinoma, but recent studies have found that the clinical features of the two diseases are different. Moreover, the pathological characteristics, survival, prognosis, and optimal ASC therapy remain unknown. This study aims to retrospectively analyze the postoperative survival of patients with early-stage ASC and to evaluate their condition after treatment with postoperative concurrent chemoradiotherapy (CCRT) and prophylactic irradiation of the para-aortic lymphatic drainage area. Methods This study enrolled 131 patients with pathologically confirmed ASC screened from 3502 patients with confirmed stage I–II cervical cancer diagnosis who had completed surgical treatments in our hospital. Among the 131 enrolled patients, 75 patients received CCRT, 33 patients received chemotherapy (CT), and 23 patients did not receive adjuvant treatment (named surgery alone (S alone). Of the 75 patients CCRT, 43 patients received prophylactic irradiation of the para-aortic lymphatic drainage area. The efficacy of the postoperative treatments of patients among groups (CCRT, CT, and S alone) was compared. Results The median follow-up time, age, and overall survival (OS) were 76 months, 43 years, and 74 months, respectively. The 3- and 5-year survival rates were 82% and 71.4%, respectively. The median disease-free survival (DFS) was 64 months. Cox regression analysis showed that postoperative adjuvant treatment modalities and positive lymph node metastases were associated with OS and DFS. Patients who received CCRT treatment had higher OS and DFS than those with CT and S alone. Prophylactic irradiation of the para-aortic lymphatic drainage area did not improve the OS and DFS of patients with CCRT treatment. However, further subgroup analysis suggested that it might improve survival rates in patients who had positive pelvic lymph nodes as confirmed by postoperative pathology. Conclusion Postoperative CCRT improved the survival rates in patients with early-stage ASC. The value of prophylactic irradiation of the para-aortic lymphatic drainage area remains debatable, but it may benefit patients with pelvic lymph node involvement.

Abstract
The management of advanced cervical cancer has evolved with time. Combined modality treatments for cervical cancer have been shown to improve clinical outcomes for these patients. The role of surgery is reviewed in this article for specific situations such as the treatment of bulky lymph nodes and even in the metastatic setting. External beam radiotherapy and brachytherapy techniques have improved which has decreased patient toxicity. Systemic therapy such as chemotherapy, immunotherapy, and novel sensitizing agents have been extensively studied and have shown promising results. The combination of these three different modalities of treatment can be tailored to each specific patient to achieve the best outcomes. We review the recent advances and various international guidelines for the management of cervical cancer in this article.

Abstract
BACKGROUND We aimed to evaluate the value of prophylactic extended-field intensity-modulated radiation therapy (IMRT) in the treatment of locally advanced cervical cancer with multiple pelvic lymph node metastases (≥2) and negative common iliac and paraaortic lymph nodes. MATERIAL AND METHODS Thirty-four patient with newly diagnosed cervical cancer (IB1-IVA) and multiple pelvic lymph node metastases (≥2) confirmed by computed tomography and magnetic resonance imaging were randomly divided into an extended-field group (17 patients) and a pelvic-field group (17 patients). In the extended-field group, we added the drainage area of paraaortic lymph nodes on the pelvic field. The pelvic field was administered Dt 45.0 to 50.4 Gy, while the drainage area of paraaortic lymph nodes was administered Dt 40.0 to 45.0 Gy. Both groups were given Irl92 intracavitary radiotherapy after 3 weeks of external irradiation. The total dose of point A was 25.0 to 30.0 Gy, fractional 6.0 to 7.0 Gy. All patients had concurrent platinum-based chemotherapy once weekly until the end of radiotherapy. RESULTS No paraaortic lymph node metastasis was found in the extended-field group (P=0.0184), and disease-free survival (DFS) was prolonged (P=0.0286). Adverse effects in patients with III-IV degree myelosuppression were increased in the extended-field group (P=0.0324). However, all patients recovered after symptomatic treatment. CONCLUSIONS Prophylactic extended-field IMRT with chemotherapy reduced the metastasis rate of paraaortic lymph nodes and prolonged the DFS in patients with locally advanced cervical cancer and multiple pelvic lymph node metastases (≥2), while the toxic adverse effects were tolerated.

Risk factors for nodal failure after radiochemotherapy and image guided brachytherapy in locally advanced cervical cancer: An EMBRACE analysis. Radiother Oncol 2021; 163:150-158. [PMID: 34480958 DOI: 10.1016/j.radonc.2021.08.020] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Revised: 07/22/2021] [Accepted: 08/26/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE To assess risk factors for nodal failure (NF) after definitive (chemo)radiotherapy and image-guided brachytherapy for locally advanced cervical cancer (LACC) for patients treated in the EMBRACE I study. MATERIALS AND METHODS Data for pelvic NF and para-aortic (PAO) NF (NFPAO) were analysed. After multiple imputation, univariable and multivariable Cox-regression was performed for clinical and treatment-related variables. For patients with affected pelvic nodes but no PAO nodes at diagnosis, additional analyses were performed for two subgroups: 1. 'small pelvis' nodes in internal and external iliac, obturator, parametrial, presacral and/or common iliac (CI) region and 2. any CI nodes (subgroup of 1). RESULTS 1338 patients with 152 NF and 104 NFPAO events were analysed with a median follow-up of 34.2 months (IQR 16.4-52.7). For the entire group, larger tumour width, nodal risk groups (in particular any CI nodes without PAO nodes), local failure, and lower Hb-nadir increased the risk of NF. Elective PAO-irradiation was independently associated with a decreased risk of NFPAO (HR 0.53, 95%-CI 0.28-1.00, p = 0.05). For subgroup 1, having 'any CI nodes without PAO nodes' and local failure significantly increased NF risk. Additionally, elective PAO-irradiation was associated with less risk of NFPAO (HR 0.38, 95%-CI 0.17-0.86, p = 0.02). For subgroup 2 only local failure was associated with higher risk of NF. CONCLUSION In this patient cohort, nodal disease and tumour width at diagnosis, as well as local failure, are risk factors for NF after definitive treatment. Having either 'any PAO nodes' (with or without pelvic nodes) or 'any CI nodes' (without PAO nodes) are stronger risk factors than involvement of nodes in the small pelvis alone. Elective PAO-irradiation was associated with significantly less NFPAO, particularly in patients with nodal disease in the 'small pelvis' and/or CI region at time of diagnosis.

Abstract
PURPOSE To compare the volumes of interest and doses to the organs at risk on contrast and noncontrast scans in patients with cervical cancer who underwent prophylactic extended-field radiation therapy (EFRT). METHODS AND MATERIALS We reviewed twenty cervical cancer patients treated with prophylactic EFRT at Peking Union Medical College Hospital between March 2021 and April 2021. Each patient underwent noncontrast and contrast scans during simulation. All structures were contoured, and radiation therapy plans were created based on both scans. Student t test and Pearson correlation coefficient test were performed. RESULTS Compared with the noncontrast scan, on the contrast scan, the mean volume of the inferior vena cava expanded by 44% (P ≤ .001), and the mean volume of the para-aortic nodal clinical target volume increased by 17% (P ≤ .001). For the second portion of the duodenum, the V30 (38.2% vs 43.8%, P = .038), V35 (27.6% vs 35.1%, P = .002), V40 (18.3% vs 26.3%, P = .014), V45 (11.2% vs 18.5%, P = .008), and V50 (4.2% vs 9.1%, P = .005) were significantly lower on the noncontrast scan than on the contrast scan. For the third portion of the duodenum, the V45 (78.4% vs 81.6%, P = .03) and V50 (59.7% vs 67%, P ≤ .001) were significantly lower on the noncontrast scan than on the contrast scan. For the right kidney, the V5, V10, V15, V20, and V25 on the contrast and noncontrast scans were 85.4% versus 79.8% (P = .013), 52.5% versus 45.6% (P = .021), 25.6% versus 20.1% (P = .003), 11.1% versus 7.5% (P = .001), and 3.8% versus 2.3% (P = .027), respectively. CONCLUSIONS Compared with the noncontrast scan, expansion of the inferior vena cava on the contrast scan can lead to excessive contouring and an overdose to the duodenum and right kidney in cervical cancer patients treated with prophylactic EFRT.

Abstract
Objective The Korean Radiation Oncology Group conducted a nationwide questionnaire survey to evaluate the patterns of clinical practice for patients with cervical cancer receiving definitive radiation therapy (RT) in South Korea. Methods Practicing radiation oncologists from 93 centers in South Korea were administered a questionnaire survey via e-mail. The survey focused on demographic characteristics, diagnostic evaluation, indications for definitive RT, RT techniques, RT field and dose prescription, lymph node (LN) boost RT, brachytherapy, and chemotherapy. Results The response rate was 62.4% (58/93 institutions). Of the 2,134 patients treated at the radiation oncology department in 2019, 48.8% underwent definitive RT. The selection of patients for definitive concurrent chemoradiation therapy and RT field, and RT dose prescription varied greatly. The upper border of the pelvis was commonly used as the bony landmark for external beam RT (81%–88% of respondents). Most (96.6%) centers performed LN boost RT with median total doses of 59 Gy and 59.2 Gy for pelvic and retroperitoneal LN, respectively. With 50% of the centers offering brachytherapy, image-guided brachytherapy and volume-based prescription were applied in 48.3% and 37.9%, respectively. Upfront concurrent chemoradiation therapy with varying prescription doses was considered by 60.4% respondents in cases of supraclavicular LN metastasis. Conclusion Most differences were noted in the indications for treatment, RT field, and prescription dose. This finding can serve as a reference for establishing practical RT guidelines for the management of locally advanced cervical cancer.

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.

J Cancer 2020; 11:5099-5105. [PMID: 32742457 PMCID: PMC7378915 DOI: 10.7150/jca.45520] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2020] [Accepted: 06/14/2020] [Indexed: 12/24/2022] Open
Abstract
Objective: Previous studies have shown that prophylactic extended-field irradiation can reduce para-aortic lymph node failure (PALNF) rates in patients with cervical cancer. As such, this type of irradiation may particularly benefit patients with a high risk of PALNF. In the present study, we analyzed the risk factors for PALNF in patients with cervical cancer treated with pelvic irradiation in order to identify potential indications of prophylactic extended-field irradiation. Methods: We evaluated patients with 2018 FIGO stage IB3-IIIC1 cervical cancer who were treated with definitive pelvic radiotherapy or concurrent chemoradiotherapy at our institution between 2011 and 2014. Univariate and multivariate analyses were performed to identify risk factors for PALNF. Results: We included 572 patients in the study. The median follow-up period was 37.9 months. Eighteen patients (3.1%) first site of tumor relapse was the para-aortic lymph nodes, and thus showed PALNF. Using multivariate Cox regression analysis, we identified two significant risk factors for PALNF: tumor extension to the pelvic wall (hazard ratio, HR 3.60, p=0.026) and ≥ 2 pelvic MLNs (HR 5.30, p=0.005). For patients with and without risk factors, the 3-year overall survival, disease-free survival, and PALNF rates were 77.3% and 90.1% (p<0.001), 56.4% and 83.1% (p<0.001), and 12.0% and 2.3% (p<0.001), respectively. Conclusion: Tumor extension to the pelvic wall and ≥ 2 pelvic MLNs are positively associated with PALNF after pelvic irradiation in patients with cervical cancer. Further trials will be required to validate whether patients with these two risk factors may benefit from prophylactic extended-field irradiation.

Abstract
Supplemental digital content is available in the text. Objective The aim of the study was to evaluate the efficacy and toxicity of prophylactic extended-field radiation therapy (RT) for cervical cancer patients treated with concurrent chemoradiotherapy (CCRT). Methods Records of patients with cervical cancer without para-aortic metastatic lymph nodes who were treated with definitive RT or CCRT between January 2011 and December 2014 were reviewed. Patients were classified into the pelvic RT and extended-field RT groups. An additional dose of 50.4 Gy in 28 fractions was delivered to para-aortic lymph node regions for patients in the extended-field RT group. Cox regression and propensity-score matching (1:1) were used to compare the overall survival (OS), disease-free survival (DFS), distant failure, and para-aortic lymph node failure (PALNF) between the pelvic RT and extended-field RT groups. Results A total of 778 patients were analyzed. Of them, 624 patients were treated with pelvic RT and 154 patients received extended-field RT. The median follow-up period was 37.5 months. In multivariate analysis, extended-field RT was an independent prognostic factor of distant failure (hazard ratio [HR] = 0.49, 95% confidence interval [CI] = 0.26–0.90, P = 0.023) and PALNF (HR = 0.012, 95% CI = 0.00–0.49, P = 0.019). However, it was not significant in predicting OS (P = 0.546) and DFS (P = 0.187). With propensity-score matching, 108 pairs of patients were selected. The 3-year OS, DFS, local control, distant failure, and PALNF rates in the pelvic RT and extended-field RT groups were 87.1% and 85.7% (P = 0.681), 71.0% and 80.6% (P = 0.199), 86.6% and 85.0% (P = 0.695), 21.7% and 7.0% (P = 0.016), and 6.6% and 0% (P = 0.014), respectively. The incidences of grade 3 or greater chronic toxicities were 3.5% and 6.5% in the pelvic RT and extended-field RT groups, respectively (P = 0.097). Conclusions Prophylactic extended-field RT was associated with decreased distant failure and PALNF and showed a trend in improving DFS in patients with cervical cancer treated with CCRT.

Abstract
The current standard of care for locally advanced cervical cancer is whole pelvis and para-aortic radiation when indicated, delivered concomitantly with chemotherapy and brachytherapy. Para-aortic node involvement is a predictor of survival in locally advanced disease but presence of metastases is difficult to determine because the currently available imaging methods lack enough sensitivity to be able to detect accurately para-aortic metastases when surgical staging is not feasible. The objective of this review is to describe the current status of para-aortic lymph node irradiation in locally advanced cervical cancer. It includes analysis of the diagnostic imaging and surgical approaches for assessment of para-aortic lymph node dissemination, together with indications for radiotherapy and radiotherapeutic techniques.

Abstract
Cervical cancer remains a prevalent and deadly disease in low-income countries, especially among young and otherwise healthy women. Multimodality treatment has led to a significant improvement in outcomes for patients with locally advanced disease, and this is mainly because of the incorporation of platinum-based chemoradiotherapy in current treatment protocols. However, locally advanced tumors are associated with a greater risk for para-aortic lymph node (PALN) involvement, which is an important adverse prognostic factor. Most staging techniques have low accuracy for detection of disease in this area, which could lead to understaging and undertreatment. Meanwhile, patients with PALN disease are underrepresented in trials addressing the treatment of advanced cervical cancer and a few studies have been directed at this population. The aim of this review is to analyze the current data regarding staging and treatment of cervical cancer with PALN disease to determine which strategy is best when managing these patients.

Abstract
Purpose This study aimed to evaluate whether prophylactic extended-field pelvic radiotherapy (EF-PRT) yields better results than standard whole pelvic radiotherapy (WPRT) in patients with pelvic lymph node-positive cervical cancer treated with concurrent chemoradiotherapy (CCRT). Materials and Methods A total of 126 cases of stage IB-IVA cervical cancer that had pelvic lymph node involvement in magnetic resonance imaging and were treated with CCRT between 2000 and 2016 were reviewed. None of the patients had paraaortic lymph node (PALN) metastases. The patients were classified to two groups, namely, those treated with EF-PRT, including prophylactic para-aortic radiotherapy, and those treated only with WPRT. The median dose to the PALN area in patients treated with EF-PRT was 45 Gy. All patients received concurrent cisplatin-based chemotherapy. Results Overall, 52 and 74 patients underwent EF-PRT and WPRT, respectively. Patient characteristics and irradiated dose were not significantly different, except the dose to the para-aortic area, between the two groups. The median follow-up period was 75.5 months (range, 5 to 195 months). The 10-year cumulative recurrence rate of PALN for EF-PRT vs. WPRT was 6.9% and 10.1% (p = 0.421), respectively. The 10-year disease-free survival and overall survival for EF-PRT vs. WPRT were 69.7% vs. 66.1% (p = 0.748) and 71.7% vs. 72.3% (p = 0.845), respectively. Acute gastrointestinal complications were significantly higher in EF-PRT (n = 21; 40.4%) than WPRT (n = 26; 35.1%) (p = 0.046). Late toxicities were not significantly different in both groups. Conclusion In this study, prophylactic radiotherapy for PALN does not have an additional benefit in patients with pelvic lymph node-positive cervical cancer treated with CCRT.

Abstract
Purpose The purpose of this study was to determine optimal extent of prophylactic irradiation of paraaortic lymph nodes (PALN) in patients with uterine cervical cancer who had metastatic pelvic LNs. Methods and Materials We retrospectively evaluated 103 patients with cervical cancer and pelvic lymph node metastasis who were treated with prophylactic semi-extended field radiotherapy (SEFRT) between 1990 and 2012. The semi-extended field included PALN below the second lumbar spine with prescribed doses of 45 to 50 Gy. Survival outcomes were calculated using the Kaplan-Meier method, and acute and late toxicities were scored using the Radiation Therapy Oncology Group and European Organisation for Research and Treatment of Cancer toxicity criteria. Results The median follow-up after SEFRT was 61 (range 5–296) months. Overall, 28 patients (27.2%) experienced treatment failures, which were classified as local in 8 patients (7.8%), regional in 8 patients (7.8%), and distant in 13 patients (12.6%). Of the regional failures, only two involved PALN failure around the renal artery or the renal hilum area at the upper margin of the semi-extended field. At 5 years, the overall survival was 82%. Grade 3 or higher acute gastrointestinal and genitourinary toxicities occurred in one and two patients, respectively. As a late toxicity, one patient developed grade 3 small bowel obstruction. Conclusion Prophylactic SEFRT provided favorable outcomes with little acute or late gastrointestinal toxicity. For prophylaxis of PALN recurrences, upper part of PALN might not need to be included in patients with uterine cervical cancer and metastatic pelvic LNs.
