    Abstract: To ascertain if preoperative short-term radiotherapy followed by chemotherapy is not inferior to a standard schedule of long-term chemoradiotherapy in patients with locally advanced rectal cancer. MATERIALS AND METHODS Patients with distal or middle-third, clinical primary tumor stage 3-4 and/or regional lymph node–positive rectal cancer were randomly assigned (1:1) to short-term radiotherapy (25 Gy in five fractions over 1 week) followed by four cycles of chemotherapy (total neoadjuvant therapy [TNT]) or chemoradiotherapy (50 Gy in 25 fractions over 5 weeks, concurrently with capecitabine [chemoradiotherapy; CRT] ). Total mesorectal excision was undertaken 6-8 weeks after preoperative treatment, with two additional cycles of CAPOX (intravenous oxaliplatin [130 mg/m 2 , once a day] on day 1 and capecitabine [1,000 mg/m 2 , twice a day] from days 1 to 14) in the TNT group and six cycles of CAPOX in the CRT group. The primary end point was 3-year disease-free survival (DFS). RESULTS Between August 2015 and August 2018, a total of 599 patients were randomly assigned to receive TNT (n = 302) or CRT (n = 297). At a median follow-up of 35.0 months, 3-year DFS was 64.5% and 62.3% in TNT and CRT groups, respectively (hazard ratio, 0.883; one-sided 95% CI, not applicable to 1.11; P 〈 .001 for noninferiority). There was no significant difference in metastasis-free survival or locoregional recurrence, but the TNT group had better 3-year overall survival than the CRT group (86.5% v 75.1%; P = .033). Treatment effects on DFS and overall survival were similar regardless of prognostic factors. The prevalence of acute grade III-V toxicities during preoperative treatment was 26.5% in the TNT group versus 12.6% in the CRT group ( P 〈 .001). CONCLUSION Short-term radiotherapy with preoperative chemotherapy followed by surgery was efficacious with acceptable toxicity and could be used as an alternative to CRT for locally advanced rectal cancer.

    Abstract: No randomized trials have compared hypofractionated radiotherapy (HFRT) with conventional fractionated radiotherapy (CFRT) after breast-conserving surgery in the Asian population. This study aimed to determine whether a 3.5-week schedule of HFRT is noninferior to a standard 6-week schedule of CFRT in China. PATIENTS AND METHODS Patients from 4 Chinese institutions who had undergone breast-conserving surgery and had T1-2N0-3 invasive breast cancers participated this study. Patients were randomly assigned (1:1) using a computer-generated central randomization schedule, without stratification, to receive whole-breast irradiation with or without nodal irradiation, followed by tumor-bed boost, either at a dose of 50 Gy in 25 fractions over 5 weeks with a boost of 10 Gy in five fractions over 1 week (CFRT) or 43.5 Gy in 15 fractions over 3 weeks with a boost of 8.7 Gy in three daily fractions (HFRT). The primary endpoint was 5-year local recurrence (LR), and a 5% margin of 5-year LR was used to establish noninferiority. RESULTS Between August 2010 and November 2015, 734 patients were assigned to the HFRT (n = 368) or CFRT (n = 366) group. At a median follow-up of 73.5 months (interquartile range, 60.5-91.4 months), the 5-year cumulative incidence of LR was 1.2% in the HFRT group and 2.0% in the CFRT group (hazard ratio, 0.62; 95% CI, 0.20 to 1.88; P = .017 for noninferiority). There were no significant differences in acute and late toxicities, except that the HFRT group had less grade 2-3 acute skin toxicity than the CFRT group ( P = .019). CONCLUSION CFRT and HFRT with a tumor-bed boost may have similar low LR and toxicity.

    Abstract: e20041 Background: Few studies focused on the risk-adapted therapy for advanced-stage natural killer/T-cell lymphoma (NKTCL) due to poor prognosis. Methods: Data of 406 patients with advanced-stage NKTCL from 20 Chinese institutions between 2000 and 2015 were retrospectively analyzed. To develop a prognosis index model for advanced-stage NKTCL, all patients were divided into the primary cohort from South China (n = 198) and the validation cohort from North China (n = 208). Clinical factors related to survival in the primary cohort were identified to construct a new prognosis index model. An external validation for the prognosis index model was performed in the validation cohort. Stratified by the prognosis index model, survival benefit for treatment models was assessed. Results: The median age was 42 years with the ratio of male/female of 2.5:1. Extra-nodal involvement was observed in 72.4% of patients. More than one third of patients received asparaginase (Asp)–containing chemotherapy. In addition, radiotherapy was administrated in 135 (33.3%) patients. The overall response rate (ORR) and complete remission (CR) rate were 59.3% and 38.3% in 337 available patients. The expected 3-year progression-free survival (PFS) and overall survival (OS) rates were 26.9% and 37.3%, respectively. Based on 3 clinical variables including ECOG-PS 〉 1, elevated LDH and solid organs involvement, a new prognosis index model (ASPRIN) was developed and showed superior discrimination than current models including IPI, KPI and PINK in this particular population. The expected 3-year OS rates in the primary and validation cohort were 54.8% and 52.9% in the low risk group (with 0-1 risk factor), 34.4% and 38.0% in the intermediate risk group (with 2 risk factors), 13.8% and 10.6% in the high risk group (with 3-4 risk factors), respectively. Stratified by ASPRIN model, combined radio-chemotherapy provided better survival benefit than chemotherapy alone regardless of chemotherapy regimens in the low risk group (3-year PFS 52.6% vs. 22.6%, P 〈 0.001; 3-year OS 72.8% vs. 35.8%, P 〈 0.001), while Asp–containing chemotherapy improved survival with an increase of about 10%-15% in PFS and OS compared with non–Asp–containing chemotherapy in the intermediate and high risk groups. Conclusions: The outcome of advanced-stage NKTCL is still poor and heterogeneous even in the era of Asp–containing chemotherapy, which highlighted the need of establishing more effective risk-adapted therapeutic strategies.

    Abstract: e15006 Background: To present an interim analysis of a phase III trial comparing short-course radiotherapy followed by chemotherapy with long-course chemoradiotherapy in locally advanced rectal cancer. Methods: Patients with distal or middle third, MRI diagnosed cT3-T4 or N+ rectal adenocarcinomas were randomized to either 5 x 5 Gy and 4 courses of CAPOX (experimental group) or 50 Gy delivered in 25 fractions given concurrently with capecitabine (control group). Total mesorectal excision (TME) in both groups was performed 6-8 weeks after neoadjuvant treatment. This is an interim analysis of acute toxicities for the first 127 patients who finished neoadjuvant therapy, as well as the pCR and surgical complications for the first 100 patients who received surgery. Results: From 08/30/2015 to 12/11/2016, 63 patients in experimental group and 64 in control group from 10 Chinese hospitals were analyzed. During preoperative treatment, any acute toxicities were 100% in both groups and grade III-IV 19.0% vs. 6.3% ( p= 0.03) in experimental group and control group, respectively. Full-dose completion rates of planned neoadjuvant treatment were 88.9% and 93.7% in each group ( p= 0.33), respectively. After median duration of 7 weeks and 9 weeks in experimental group and control group, TME was performed. Among the 100 patients who have finished surgery, 94.1% and 89.8% in experimental and control group had R0 resection ( p= 0.426), while 21.6% and 6.1% of them achieved pCR ( p= 0.026), respectively. There were 8 patients in experimental group diagnosed as clinical CR and refused to further radical surgery, while, none in control group ( p= 0.003). The incidences of surgical complications were similar between two groups (experimental 29.1% vs. control 26.5%; p= 0.748), with perineal healing delay as the main reason. Conclusions: The acute toxicity and surgical complication were acceptable and comparable in both groups, however, the people in experimental group showed a significantly clinical and pathological response. The short-course irradiation and consolidation chemotherapy maybe an alternative standard of care, though the final result is in prospect. Clinical trial information: NCT02533271.

    Abstract: The optimal therapy remains unclear for nasal natural killer (NK)/T–cell lymphoma. The purpose of this study is to analyze the outcome of radiotherapy as the primary treatment for localized stage IE and IIE diseases. Patients and Methods One hundred five patient cases were reviewed. There were 83 stage IE and 22 stage IIE patients. All except three patients received radiotherapy (RT) alone or RT combined with chemotherapy (CT; combined-modality therapy [CMT]). Overall, 31 patients were treated with RT alone, 34 with RT followed by CT, 37 with CT followed by RT, and three with CT alone. Results Five-year overall survival (OS) and progression-free survival (PFS) for all patients were 71% and 59%, respectively. The 5-year OS and PFS were 78% and 63% for stage IE, and 46% and 40% for stage IIE, respectively. Complete response (CR) was achieved in 91 patients (87%) after RT and/or CT. Initial RT resulted in a superior CR as compared with initial CT, with 54 (83%) of 65 patients achieving CR with initial RT, versus only eight (20%) of 40 after initial CT. For 102 patients who received RT with or without CT, the outcome of primary treatment with RT alone was compared with that of CMT. Five-year OS and PFS was 66% and 61% for RT alone, and 76% and 61%% for CMT, respectively (OS, P = .6433; PFS, P = .8391). Conclusion RT as primary therapy resulted in good outcome in early-stage disease, and the addition of CT to RT was not accompanied by an improvement in survival.

    Abstract: 3510 Background: It’s presented the results of a phase III trial of short-term radiotherapy (SCRT) combined with chemotherapy versus long-term chemoradiotherapy (LCRT) in patients with locally advanced rectal cancer (LARC). Methods: Patients with distal or middle third, T3-T4 and/or N+ rectal adenocarcinomas diagnosed by MRI, were randomly assigned to experimental group or control group. In experimental group, patients received SCRT (25 Gy / 5 fractions / 5 days), followed by four courses of CAPOX. In control group, patients received LCRT (50 Gy / 25 fractions / 35 days with concurrent capecitabine). Surgery was recommended in both groups and performed 6-8 weeks after preoperative treatment. Two or six courses of CAPOX was prescribed as the postoperative chemotherapy in experimental group and control group, respectively. This trial was a multicenter, open-label, randomized, noninferior, phase III study, and all the patients were from 16 hospitals of China. The primary endpoint for this study was 3-year disease-free survival (DFS). Results: From Aug 30, 2015 to Aug 27, 2018, 599 patients were enrolled and entered random. Finally, 591 intention-to-treat (ITT) populations were included in the analysis, 298 patients assigned to SCRT followed by chemotherapy and 293 to CRT. For the experimental group and control group, cT3 and cT4 accounted for 82.3% vs. 84.6% and 15.4% vs. 12.3%, respectively, and approximately 85% were mrN positive (85.6% vs. 84.0%). As a whole, the completion and full-dose completion rates of preoperative treatment were 82.6% vs. 95.2% (p<0.001) and 74.8% vs 93.2% (p<0.001) in the experimental and control groups, respectively. Among the 465 patients who received surgery, 16.6% and 11.8% of them achieved pCR (p=0.134), respectively. Accounting for cCR after preoperative treatment, the total rate of pCR+cCR in experimental group was 22.5% and significantly higher than control group (12.6%, p=0.001). With median follow-up 35.0 months, the HR between experimental and control of DFS was 0.883, with 1-sided noninferiority p-value 〈 0.001, so the noninferiority hypothesis was confirmed. The probability of DFS and OS at 3 years was 64.5% and 86.5% in the experimental group compared with 62.3% and 75.1% in control group. It’s observed the OS rate of the experimental group was significantly higher than that of the control group (p=0.036) and no significant difference in metastasis-free survival or loco-regional recurrence was observed. Conclusions: For LARC with high risk factors, SCRT combined with sequential chemotherapy was noninferior to CRT and could be used as an alternative to LCRT. Meanwhile, SCRT combined with chemotherapy presented a higher cCR+pCR and 3-year overall survival rates as compared with CRT. However, the long term results need to be further followed up. (ClinicalTrails No.: NCT02533271 ). Clinical trial information: NCT00833131.

    Abstract: e16195 Background: Immune checkpoint inhibitor monotherapy has emerged as a breakthrough therapy in the treatment of various cancer. However, programmed cell death (PD-1) inhibitors alone as secondary line treatment yield uncertain response in liver cancer in different studies. Despite encouraging preclinical findings that radiation primes the immune system and produces a synergistic anti-tumor immunity for durable disease control, few clinical data is published so far. To investigate the efficacy and safety of the combination of radiation and PD-1 inhibitors in metastatic and recurrent liver cancer, we proposed this study. Methods: Patients diagnosed with stage IV (American Joint Committee on Cancer Staging System 8th) or recurrent liver cancer, received radiotherapy followed by PD-1 inhibitors or concurrent radiation and PD-1 inhibitors were enrolled. Data regarding clinicopathologic characteristics, treatment protocols, response rates, toxicities, and survival were collected. Survivals were calculated from the date of the first delivery of immunotherapy using Kaplan-Meier method. Results: From April 2017 to December 2020, 34 patients were eligible. Twenty-nine (85.3%) patients were male and 5(14.7%) were female. The median age was 58 years old. Twenty-three patients (67.6%) had hepatocellular carcinoma. Totally, radiotherapy was delivered to 92 lesions (28 liver, 28 venous tumor emboli, 13 lymph nodes, 18 bone, 5 others) of these patients. The radiation dose ranged from 40Gy to 60Gy (2-5Gy per fraction). Sixteen patients, 15 patients, 5 patients, 1 patient and 1 patient received toripalimab, sintilimab, camrelizumab, nivolumab and pembrolizumab, respectively (Four patients received multiple- drugs in different time ). PD-1 inhibitors were administered very 3 weeks until progression or limiting toxicities. After treatment, 3,18 and 11 patients achieved complete response, partial response and stable disease. The response rate and disease control rate were 61.8% and 94.1%, respectively. Grade 3 adverse events were observed in 11 patients (32.4%), including 6 patients with thrombocytopenia (2 with grade 4, 4 with grade 3), 2 patients with gastrointestinal events and 3 with others. No grade 5 adverse event was recorded. The median follow up time was 16.5 months. The median overall survival (OS) time and progression free survival (PFS) time were 15.4 months and 11.3 months. One-year OS and PFS were 62.9% and 46.5%, respectively. Two-year OS and PFS were 31.8% and 11.3%, respectively. Conclusions: The combination of immunotherapy and radiotherapy was safe and tolerable. The application of radiation before or during PD-1 inhibitors delivery fostered the immune response and enhance the efficacy of immunotherapy with prolonged PFS and OS in recurrent and metastatic liver cancer. A phase II prospective trial is ongoing.

    Abstract: e16142 Background: This study aimed to assess the efficacy and safety of radiotherapy (RT) combined with regorafenib as a second or further-line treatment for advanced hepatocellular carcinoma (HCC). Methods: Patients diagnosed with advanced HCC who had received RT combined with concurrent or sequential regorafenib treatment or regorafenib plus anti-PD-1 or anti-PD-L1 immune checkpoint inhibitors (ICIs) in our hospital from April 2018 to August 2022 were reviewed. Progression-free survival (PFS) was the primary endpoint. Overall survival (OS), objective response rate (ORR), disease control rate (DCR) and toxicity were the secondary endpoints. Results: Fifty-four patients were included with a median age of 56 (38-73). Forty-six patients (85.2%) were in Barcelona Clinic Liver Cancer (BCLC) stage C. Thirty-seven patients (68.5%) had portal vein tumor thrombosis and 15 (27.8%) had extrahepatic metastasis. All patients received intensity modulated radiation therapy, while 26 patients were concurrently treated with regorafenib and 28 patients were sequentially treated with regorafenib. The median dose of radiotherapy was 57.2Gy (30-69.8Gy). Anti-PD-1/anti-PD-L1 agents were applied to 31 patients at the use of regorafenib. The median PFS was 11.3 months. The 3-year PFS and OS were 23.8% and 51.9%, respectively. Treatment response after RT was shown. For tumor in in-field of RT, ORR was 75.9% and 92.6% according to RECIST and mRECIST criteria, respectively. No progression was found in in-field of RT. Out-field recurrence in liver and distance metastasis was the main failure pattern. For all lesions, the ORR was 40.7% and DCR was 55.6%, respectively. There was no significant difference of PFS and OS between patients with and without ICIs ( p 〉 0.05). Univariate analysis showed that alpha-fetoprotein tumor marker level ≥ 1000 ng/ml ( p = 0.049), Albumin-Bilirubin grade ≥ 2 ( p = 0.012) and multiple intrahepatic tumors ( p = 0.031) were the risk factors of lower PFS. Patients were well tolerated to the treatments. The most common grade 3 toxicities were hand-foot syndrome (11.1%), fatigue (3.7%) and hypertension (1.9%). Classical or non-classical radiation-induced liver disease was not noted. Conclusions: Radiotherapy concurrently or sequentially with regorafinib treatment is an effective, well tolerated, and promising regimen in advanced HCC patients. [Table: see text]
