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.

Abstract Background To compare irradiation dose to the second and third portions of duodenum (Duo2 and Duo3) with a new refined and old delineation method of para-aortic region for patients with locally advanced cervical cancer (LACC) receiving prophylactic extended-field radiotherapy (EFRT). Methods Twenty consecutive patients with LACC were treated with prophylactic EFRT from January 2016 to January 2017 at our institute. Two delineation methods of para-aortic region were designed for each patient, the old delineation method ensured a full coverage of aortic and inferior vena cava, while the right paracaval region above L3 was omitted from CTV in the new delineation method. Patients received a dose of 50.4Gy in 28 fractions for PCTV and a dose of 60.2Gy in 28 fractions for PGTV with volumetric-modulated arc therapy (VMRT). The dose delivered to Duo2 and Duo3 with these two delineation methods were compared. Results All treatment plans achieved excellent target volume coverage with 95% of PCTV receiving 50.4Gy and 95% of PGTV receiving 60.2Gy. There was no difference between delineation methods in low dose level (V5, V10, V15, V20, V25) for Duo2 and Duo3. The V30, V35, V40, V45, V50, Dmax, Dmean and D2cc for Duo2 with the new and old delineation methods were 55.76% vs 80.54% (P = 0.009), 34.72% vs 70.91% (P < 0.001), 18.69% vs 55.46% (P < 0.001), 8.20% vs 41.49% (P < 0.001), 1.86% vs 21.60% (P < 0.001), 49.58Gy vs 52.91Gy (P = 0.002), 30.38Gy vs 39.22Gy (P = 0.001) and 37.90Gy vs 48.64Gy (P < 0.001) respectively. For Duo3, the new delineation method achieved significant advantages in V30, V35, V40, V45, V50 and Dmean over the old one (96.82% vs 99.25%, P = 0.021; 89.65% vs 97.21%, P = 0.001; 79.50% vs 93.18%, P < 0.001; 65.63% vs 82.93%, P < 0.001; 43.39% vs 65.60%, P < 0.001; 46.09Gy vs 49.24Gy, P < 0.001), no deference was observed regarding D2cc and Dmax with these two delineation methods. Conclusion With the new delineation method of para-aortic area in prophylactic EFRT, significant reduction of irradiation dose to the second and third portions of duodenum in high dose area was obtained. This may further lower the incidence of duodenal toxicity when performing prophylactic EFRT for patients with LACC.

TPS5116 Background: Cervical cancer is a global health problem and the most common cause of cancer-related death among women in developing nations. Despite the recently developed cervical cancer vaccine, many women will continue to die from cervical cancer for many decades unless existing treatments can be improved. Unscreened women often present with locally-advanced disease that has a 5 year overall survival (OS) rate of 60% or less following standard chemo-radiation. Although some evidence suggests that adjuvant chemotherapy following chemo-radiation may be of value, its role remains controversial. Methods: OUTBACK is a randomized phase III Gynecologic Cancer InterGroup (GCIG) trial designed and led by the Australia New Zealand Gynaecological Oncology Group (ANZGOG) in collaboration with the NHMRC Clinical Trials Centre. Participating countries (groups) include Australia and New Zealand (ANZGOG), India, the USA and Canada (GOG, RTOG). OUTBACK is suitable for women with locally advanced cervical cancer (FIGO stage IB1 and node positive, IB2, II, IIIB or IVA). The primary objective is to determine if the addition of adjuvant chemotherapy to standard cisplatin-based chemo-radiation improves OS. Women are randomized to either A) standard cisplatin-based chemo-radiation or B) standard cisplatin-based chemo-radiation followed by 4 cycles of carboplatin and paclitaxel chemotherapy. Secondary objectives are to compare progression-free survival, treatment-related toxicity, patterns of disease recurrence, quality of life and psycho-sexual health, and the association between radiation protocol compliance and outcomes. Blood and tumour samples are collected from consenting patients for future translational studies. 780 women will be enrolled to determine if the addition of adjuvant chemotherapy can improve the 5-year OS rate by ≥ 10%. OUTBACK opened in Australia and New Zealand in 2011. In early 2012 the trial opened in the USA and activation of GOG sites is ongoing. 15 patients have been randomized. It is expected that RTOG and India will open the trial later this year with recruitment increasing substantially once all sites are activated.
