ObjectiveThe objective of this study was to assess prospectively the clinical outcomes of low-dose prophylactic extended-field, intensity-modulated radiotherapy (IMRT) plus concurrent weekly cisplatin for patients with stage IB2-IIIB cervical cancer, positive pelvic lymph nodes (PLNs), and negative para-aortic lymph nodes (PALNs).MethodsThirty-two patients with stage IB2-IIIB cervical cancer with positive PLN and negative PALN were included prospectively. All lymph nodes were assessed with positron emission tomography. The PALN field, including lymphatics from the superior border of L1 to the L4-L5 interphase, was irradiated concurrently with pelvic IMRT with a prescribed dose of 40 Gy in 25 fractions. Chemotherapy consisted of cisplatin delivered weekly at a dose of 40 mg/m2. Using historical controls treated with pelvic radiotherapy, the survival curves were compared to assess the difference between the 2 treatment periods.ResultsThirty-one patients completed the allocated extended-field IMRT, and all finished the planned pelvic IMRT and brachytherapy. Acute ≥ grade 3 gastrointestinal, genitourinary, and hematologic toxicities were seen in 2, 1, and 18 patients, respectively. During a median follow-up of 33 months, 5 patients developed out-field distant recurrences. One patient had a late grade 3 gastrointestinal complication, and 1 patient had genitourinary toxicity. The 3-year actuarial overall survival, disease-free survival, and distant metastasis–free survival for the study cohort and historic controls were 87% versus 62% (P = 0.02), 82% versus 54% (P = 0.02), and 79% versus 57% (P = 0.01), respectively.ConclusionsExtended-field IMRT of 40 Gy to the PALN plus concurrent cisplatin can effectively eradicate subclinical disease at the PALN and improve the outcome for patients with PLN-positive stage IB2-IIIB cervical cancer.

ObjectiveRetrospectively, to assess the toxicity of delivering postoperative extended-field intensity-modulated radiotherapy (EF-IMRT) and concurrent cisplatin chemotherapy for patients with cervical cancer with a pathologically confirmed positive common iliac node and/or a para-aortic node.MethodsEach patient received postoperative EF-IMRT and concurrent cisplatin chemotherapy. The clinical target volume included regional lymph node regions (obturator; common, internal, and external iliac nodal regions; presacral region; and para-aortic regions) and the upper 2.0 cm of the vagina and paravaginal soft tissue lateral to the vagina. The acute and late toxicity were scored using the Common Terminology Criteria for Adverse Events (CTCAE) and the Radiation Therapy Oncology Group late radiation morbidity scoring criteria, respectively.ResultsFifty-eight patients were treated with postoperative EF-IMRT and concurrent cisplatin chemotherapy. The median follow-up was 34 months. Eighteen patients (31%) had recurrence. The region of recurrence was in-field in 2 patients (3.4%) and out-field in 16 patients (27.6%). Acute grade 3 or higher gastrointestinal, genitourinary, and hematologic toxicity occurred in 2, 1, and 11patients, respectively. Three patients (5.1%) had late grade 3 toxicities. Thirteen patients experienced ovarian transposition; of these, 10 patients (77%) maintained ovarian function. Forty-one patients (71%) were alive at the last follow-up.ConclusionsConcurrent cisplatin chemotherapy with postoperative EF-IMRT was safe and well tolerated. The acute and late toxicities are acceptable. The locoregional control rates are hopeful, although distant metastases continue to be the primary mode of failure. Postoperative EF-IMRT provides an opportunity to preserve endocrine function for patients with ovarian transposition.

Abstract Objective This study was conducted to evaluate the efficacy and toxicity of extended-field intensity-modulated radiation therapy combined with concurrent chemotherapy in patients with cervical cancer with positive para-aortic lymph nodes (PALN). Methods From September 2007 to December 2014, a total of 59 patients who had cervical cancer with para-aortic lymph node metastasis were treated with concurrent chemoradiotherapy at our institution. A dose of 45–50.4 Gy in 25–28 fractions with extended-field intensity-modulated radiation therapy was prescribed to planning target volume, and a dose of 30–36 Gy in 5–6 fractions was prescribed to Point A with high-dose-rate brachytherapy. A concurrent first-line cisplatin-based chemotherapy regimen was used. Results The median duration of follow-up was 32.1 months (range, 3.2–103.7 months). The 2- and 3-year overall survival, disease-free survival and local control rates were 69.0 and 52.8%, 45.0 and 41.3% and 83.4 and 81.0%, respectively. Distant metastasis was the major pattern of treatment failure, which occurred in 26 patients (44.1%). The incidence of Grade 3 or greater acute hematologic, gastrointestinal and genitourinary toxicity was 50.9, 1.7 and 3.4%, respectively. Only one patient had both Grade 3 late gastrointestinal and genitourinary toxicity. Conclusions The study found that extended-field intensity-modulated radiation therapy combined with concurrent chemotherapy was safe and effective in patients who had cervical cancer with positive PALN.

Abstract Background: This study aimed to evaluate the therapeutic efficacy of extended-field intensity-modulated radiotherapy (EF-IMRT) and dosage boost for positive lymph nodes, prognostic factors, treatment failure, and toxicity for Federation of Gynecology and Obstetrics (FIGO) stage IIICr and IVA cervical cancer patients with positive regional lymph nodes.Methods: We retrospectively evaluated 34 patients with stage IIICr and IVA who had received treatment in our institute between 2013 and 2016. Patients with stage IVA cervical cancer who had been enrolled in the analysis all had positive regional lymph nodes (pelvic or/and para-aortic). All 34 patients were treated with EF-IMRT and simultaneously integrated boost-IMRT (SIB-IMRT) for lymph node metastasis with concurrent chemotherapy and brachytherapy. Positive regional lymph nodes (short-axis diameter ≥5 mm in computed tomography [CT] or magnetic resonance imaging [MRI]) remaining after SIB-IMRT were then treated with sequential boost-IMRT (SeB-IMRT). The prognostic factors for overall survival (OS); disease-free survival (DFS); local control rate (LCR); regional control rate (RCR); distant metastasis-free survival (DMFS), including age, FIGO stage, pretreatment hemoglobin (HB) level, tumor size, para-aortic lymph node (PALN) metastasis, point A equivalent dose in 2-Gy fractions (EQD2 dose), concurrent chemotherapy, and adjuvant chemotherapy cycles, were analyzed.Results: Complete response (CR) was achieved in 31 (91.2%) patients with acceptable adverse effects. Notably, the three-year OS, DFS, LCR, RCR, DMFS for these patients were 73.5%, 70.6%, 88.1%, 87.9%, and 81.6%, respectively. In particular, the three-year OS, DFS, LCR, RCR, and DMFS of patients with positive PALNs was 41.7%, 33.3%, 65.6%, 72.2%, and 60.2%, respectively. The corresponding values in patients without positive PALNs were 90.9%, 90.9%, 100%, 95.5%, and 90.9%, respectively.Conclusions: Our study suggested that the EF-IMRT and nodal dosage boost decreased regional node failure and that patients with stage IIIC1r and IVA cervical cancer without PALN metastasis who received EF-IMRT and SIB-IMRT with or without SeB-IMRT had a significant survival advantage in terms of the DFS and OS.

Abstract Background Although the prognosis of locally advanced cervical cancer has improved dramatically, survival for those with stage ⅢB-ⅣA disease or lymph nodes metastasis remains poor. It is believed that the incorporation of intensity-modulated radiotherapy into the treatment of cervical cancer might yield an improved loco-regional control, whereas more cycles of more potent chemotherapy after the completion of concurrent chemotherapy was associated with a diminished distant metastasis. We therefore initiated a non-randomized prospective phaseⅡ study to evaluate the feasibility of incorporating both these two treatment modality into the treatment of high risk locally advanced cervical cancer. Objectives to determine whether the incorporation of intensity-modulated radiotherapy and the addition of adjuvant paclitaxel plus cisplatin regimen into the treatment policy for patients with high risk locally advanced cervical cancer might improve their oncologic outcomes. Study Design: Patients were enrolled if they had biopsy proven stage ⅢA-ⅣA squamous cervical cancer or stage ⅡB disease with metastatic regional nodes. Intensity-modulated radiotherapy was delivered with dynamic multi-leaf collimators using 6MV photon beams. Prescription for PTV ranged from 45.0 ~ 50.0Gy at 1.8Gy ~ 2.0Gy/fraction in 25 fractions. Enlarged nodes were contoured separately and PTV-nodes were boosted simultaneously to a total dose of 50.0–65 Gy at 2.0- 2.6Gy/fraction in 25 fractions. A total dose of 28 ~ 35Gy high-dose- rate brachytherapy was prescribed to point A in 4 ~ 5 weekly fractions using an iridium- 192 source. Concurrent weekly intravenous cisplatin at 30mg/m2 was initiated on the first day of radiotherapy for over 1-hour during external-beam radiotherapy. Adjuvant chemotherapy was scheduled within 4 weeks after the completion of concurrent chemo-radiotherapy and repeated 3 weeks later. Paclitaxel 150 mg/m2 was given as a 3-hour infusion on day1, followed by cisplatin 35 mg/m2 with 1-hour infusion on day1-2 (70 mg/m2 in total). Results Fifty patients achieved complete response 4 weeks after the completion of the treatment protocol, whereas 2 patients had persistent disease. After a median follow-up period of 66 months, loco-regional (including 2 persistent disease), distant, and synchronous treatment failure occurred in 4 ,5, and 1, respectively. The 5-year disease-free survival, loco-regional recurrence-free survival, distant-metastasis recurrence-free survival was 80.5%, 90.3%, and 88.0%, respectively. Four of the patients died of the disease, and the 5-year overall survival was 92.1%. Most of the toxicities reported during concurrent chemo-radiotherapy were mild and transient. The occurrence of hematological toxicities elevated mildly during adjuvant chemotherapy, as 32% (16/50) and 4% (2/50) patients experienced grade 3–4 leukopenia and thrombocytopenia, respectively. Grade 3–4 late toxicities were reported in 3 patients. Conclusions The incorporation of intensity-modulated radiotherapy and adjuvant paclitaxel plus cisplatin chemotherapy were highly effective and well-tolerated in the treatment of high-risk locally advanced cervical cancer. The former yields an improved loco-regional control, whereas distant metastases could be effectively eradicated with mild toxicities when adjuvant regimen was prescribed.

ObjectiveTo evaluate disease outcomes and toxicity in patients with cervical cancer treated with extended-field intensity-modulated radiotherapy.Materials and MethodsWe included all patients treated with extended-field intensity-modulated radiotherapy and concurrent weekly cisplatin from 2003 to 2010 at 2 institutions. Overall survival and disease-free survival were estimated using Kaplan-Meier method. Locoregional failure (LRF), distant failure, and competing mortality were calculated using cumulative incidence functions. Acute and late toxicity were graded using Common Terminology Criteria for Adverse Events (CTCAE) and Radiation Therapy Oncology Group late radiation morbidity scoring criteria, respectively.ResultsThe study included 21 patients, 14 and 20 of which had positive para-aortic and pelvic nodes, respectively. The median follow-up was 22 months. Eighteen-month overall survival and disease-free survival were 59.7% (95% confidence interval [CI], 41.2%–86.4%) and 42.9% (95% CI, 26.2%–70.2%). Eighteen-month cumulative incidences of LRF, distant failure, and competing mortality were 9.5% (95% CI, 1.5–26.8%), 42.9% (95% CI, 21.3–62.9%), and 4.8% (95% CI, 0.3–20.2%), respectively. Eighteen-month cumulative incidences of late grade 3 or higher-grade genitourinary and gastrointestinal toxicity were 4.8% (95% CI, 0.2%–20.3%) and 0%, respectively.ConclusionsIntensity-modulated extended-field radiotherapy was associated with low rates of late toxicity and LRF. High rates of distant failure indicate that this group of patients could benefit from intensified systemic therapy.
