China emerges as a major country in nuclear energy development and the application of nuclear and radiologic technology. The diagnosis and treatment of acute radiation syndrom (ARS) caused by external irradiation represent a core function in the country′s medical rescue of nuclear and radiological emergencies. Clinically, ARS manifests hematopoietic, gastrointestinal, cutaneous, and central nervous system syndromes, with specific clinical manifestations, signs, severity, and prognosis strongly correlated with radiation dose. China has established a number of national and provincial centers for treating radiation-induced damage. Nevertheless, most medical staff have limited experience in ARS treatment. This consensus presents a summary of recent experience in treating ARS of China. In combination with recommendations from international organizations such as the World Health Organization (WHO), this consensus proposes key evidence of critical clinical issues of ARS, covering all links in the rescue of external irradiation-induced ARS. Initially, clinical diagnosis, syndromes, and severe degrees should be determined based on clinical symptoms and dose estimates. It is necessary to normalize clinical treatment measures for hematopoietic recovery, gastrointestinal injury treatment, infection control, symptomatic treatment, and multi-organ function preservation. To this end, this consensus offers cautions. This consensus provides principles of treatment with traditional Chinese medicine, psychological intervention, and follow-up. Additionally, it highlights multidisciplinary collaboration. It is recommended that this consensus be applied in relevant treatment centers.

Upper tract urothelial carcinoma (UTUC) patients have high recurrent rate and poor survival. Most of the previous studies of adjuvant chemotherapy in UTUC were retrospective and the results were controversial. Recent clinical trials support that adjuvant chemotherapy can improve disease-free survival of patients with locally advanced UTUC and platinum based regimens are standard adjuvant treatment. Currently the clinical trials results about effect comparison between adjuvant treatment and neoadjuvant treatment are limited. With the development of targeted therapy and immunotherapy, combinations with novel agents in the adjuvant setting might further improve the prognosis for locally advanced UTUC.

Objective: To investigate the incidence and clinical characteristics of urothelial carcinoma (UC) accompanied with multiple primary carcinoma (MPC). Methods: The clinical data of 121 UC patients with MPC in Peking University Third Hospital from January 2010 to May 2018 were retrospectly analyzed. Results: UC patients with MPC accounted for 9.74% (121/1 242) of all the UC patients. The ratio of male to female patients was 2.10∶1 in the total MPC patients, but it was 1∶1 in the upper urinary tract MPC subgroup. The MPC patients were more common in elderly people, whose medium age was 68 (32-93) years old. Of all the location (131 person-time) of other tumors besides UC, the digestive system tumors occurred most frequently, accounting for 41.98% (55/131), followed by the urinary and male reproductive system tumors (20.61%, 27/131) and the female reproductive system (12.21%, 16/131). The proportion of the digestive system tumors (47.37%, 9/19) was the highest in the upper urinary tract MPC, with a total number of the other primary cancer of 19 person-time. However, the proportion of the urinary and male reproductive system tumors (37.14%, 13/35) was higher in the synchronous MPC group, with a total number of the other primary cancer of 35 person-time. Some patients had a history of radiotherapy and/or chemotherapy before UC was diagnosed. We also observed 2 cases of genetically confirmed Lynch syndrome. The median overall survival (mOS) of UC patients with MPC was 132 months, and the mOS of patients with UC as the first malignancy (including synchronous MPC and UC as the first malignancy in metachronous MPC) was 120 months. The mOS of the synchronous MPC group was 84 months, which was significantly shorter than 178 months of metachronous MPC group (χ² =14.029, P<0.001). Conclusions The incidence of UC accompanied with MPC is not low, and the most common sites of MPC are the digestive system and reproductive system. Therefore, screening for MPC in UC patients, especially those with personal or family history of tumors, as well as elderly patients, may help early diagnosis and treatment of MPC patients and improve their prognoses.
