Background: Primary liver cancer, of which around 75–85% is hepatocellular carcinoma in China, is the fourth most common malignancy and the second leading cause of tumor-related death, thereby posing a significant threat to the life and health of the Chinese people. Summary: Since the publication of Guidelines for Diagnosis and Treatment of Primary Liver Cancer in China in June 2017, which were updated by the National Health Commission in December 2019, additional high-quality evidence has emerged from researchers worldwide regarding the diagnosis, staging, and treatment of liver cancer, that requires the guidelines to be updated again. The new edition (2022 Edition) was written by more than 100 experts in the field of liver cancer in China, which not only reflects the real-world situation in China but also may reshape the nationwide diagnosis and treatment of liver cancer. Key Messages: The new guideline aims to encourage the implementation of evidence-based practice and improve the national average 5-year survival rate for patients with liver cancer, as proposed in the “Health China 2030 Blueprint.”

PURPOSE: 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/m², once a day] on day 1 and capecitabine [1,000 mg/m², 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.

Purpose: 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.
