Abstract
PURPOSE The standard treatment of non-Hodgkin lymphoma (NHL) comprises combined modality treatment, radiotherapy (RT), and chemotherapy with rituximab which has significantly improved both disease-free survival (DFS) and overall survival (OS). However, there is no uniformity in radiation dose usage in these patients. In this retrospective study, we compared lower radiation dose with higher in patients with aggressive NHL. MATERIALS AND METHODS From 2007 to 2017, treatment records of all high-grade NHL or diffuse large B-cell lymphoma and non-central nervous system NHL were included. We compared response rates, OS and DFS of patients who received ≤30 Gy RT to those with >30 Gy. Univariate and multivariate analyses were done to determine factors affecting prognosis, i.e., age, sex, stage, International Prognostic Index (IPI), adding rituximab, and radiation dose. RESULTS A total of 184 NHL patients treated with combined modality or radiation alone having complete follow-up details were analyzed. At median follow-up of 66.8 months, 5-year OS was 72.8% in high-dose group versus 69.9% in low-dose group (p = 0.772) and 5-year DFS 64.7% versus 64.1% (p = 0.871). Patients having early-stage disease receiving low dose and those with advanced disease treated with >30 Gy had better OS and DFS though not statistically significant. Adding rituximab was associated with significantly better OS and DFS irrespective of radiation dose delivered. High IPI score and omitting rituximab were the only factors that significantly worsened both OS and DFS. Acute radiation toxicities were comparable in both groups (p = 0.82). Among late toxicities, no patient developed a second malignancy and 5% died due to cardiovascular complications (p = 0.595) though only two patients (1.1%) had received thoracic radiation. CONCLUSION The two groups had comparable response rates, acute toxicities, DFS and OS. This study suggests that RT dose reduction may be possible in high-grade NHL without compromising the DFS and OS.

Abstract
Follicular lymphoma (FL) is a mature B-cell neoplasm with a mostly indolent course. Genetic hallmark characteristics are Bcl-2 overexpression based on a t(14;18) translocation and additional secondary genetic and epigenetic aberrations. Standard treatment for early-stage patients has curative intent and usually consists of radiotherapy with or without rituximab. In the advanced stage, the main therapeutic focus is on prolonged remissions. Therefore, treatment in asymptomatic patients is usually deferred. Symptomatic patients are subject to immunochemotherapy induction followed by antibody maintenance. Importantly, about one in five patients subsequently experiences a more rapid clinical course, achieving only short remissions with multiple relapses (POD24). In those patients, there is still an urgent need for improved therapeutic options. Accordingly, a plethora of targeted and immunotherapeutic options, including immunomodulatory drugs, small molecule inhibitors, monoclonal antibodies as well as bispecific T-cell engager antibodies and CAR-T cell products have been recently evaluated in such relapsed high-risk patients.

Abstract
OBJECTIVE To evaluate the efficacy of rituximab combined with GDP regimen (gemcitabine + cisplatin + dexamethasone) in the treatment of non-Hodgkin lymphoma and its impact on the immune function of patients. METHODS Clinical data of 88 patients with non-Hodgkin lymphoma (NHL) treated in Affiliated Hospital of Yan'an University from February 2017 to February 2019 were analyzed retrospectively. Among them, 40 patients treated with the second-line regimen (gemcitabine + cisplatin + dexamethasone) were served as the control group, and 48 patients received additional rituximab were as the observation group. The therapeutic effect, incidence of adverse reactions, levels of complement (C3, C4) and immunoglobulin [immunoglobulin (Ig) G, IgM, IgA] before and after treatment were compared between the two groups. Cox regression analysis was used to analyze the prognostic factors of patients. RESULTS The total response rate of patients in observation group was higher than that in the control group (P<0.05). There was no significant difference in the incidence of adverse reactions (hair loss, nausea and vomiting, thrombocytopenia, anemia and bone marrow suppression) between the two groups (P>0.05). After treatment, the levels of C3 and C4 in both groups were lower than those before treatment, and the decrease in observation group were more evident than that in control group (P<0.05). No notable fluctuation was observed in the levels of IgG, IgM and IgA in both groups between before and after treatment (P>0.05). Cox regression analysis found that Ann Arbor stage and pretreatment disease status were the factors affecting the prognosis of patients. CONCLUSION Rituximab combined with GDP regimen has a significant effect on the treatment of non-Hodgkin lymphoma, and Ann Arbor stage and pretreatment disease state are prognostic factors for patients with NHL.

Prospective, randomized, controlled, noninferiority clinical trial to evaluate the safety and efficacy of absorbable macroporous polysaccharide composites as adjunct to hemostasis during open surgery.

Abstract
BACKGROUND To address intraoperative bleeding in cardiac surgery, reducing blood transfusion requirements, is mandatory to achieve effective hemostasis. Hemostatic agents may limit localized persistent bleeding. The introduction of carboxymethyl-chitosan component into the hemostatic agent and the application of the radiation crosslinking technique maintain its capacity for achieving intraoperative hemostasis, thus increasing the clinical utility. METHODS A prospective, noninferiority and randomized controlled clinical trial to compare the safety and efficacy of absorbable macroporous polysaccharide composites (AMPC, treatment group) with compound microporous polysaccharide hemostatic powder (CMPHP, control group) (2:1 ratio) as adjuncts to hemostasis in open surgery. The main indication was used for hemostasis in various traumatic hemorrhage areas, including cardiothoracic, vascular, and general surgery. The primary endpoint was success rate of hemostasis within 300 s (at a 10% noninferiority margin). The secondary endpoint was hemostasis time. Both endpoints were assessed in the modified intention-to-treat (MITT) population. Safety parameters were assessed. This study is fully compliant with the CONSORT statement. RESULTS Randomized patients in AMPC and CMPHP groups were 168 and 84, respectively. In MITT population, the success rates of hemostasis within 300 s were 98.8% (163 of 165) in AMPC and 94.0% (78 of 83) in CMPHP (treatment difference 4.8% [95% CI -0.57% to 10.20%]). AMPC was thus noninferior to CMPHP. Hemostasis time (median [interquartile range]) with AMPC (87 [52.5, 180] s) was better than CMPHP (110 [54.5, 181] s). Changes in laboratory parameters over time and shifts to abnormal values were typical of surgeries and similar between two groups. No noticeable adverse effects associated with AMPC or CMPHP were observed. CONCLUSIONS AMPC is well tolerated as topical hemostatic agent, noninferior to commercial CMPHP, and exhibits excellent safety. This study provides a novel hemostatic agent which appears to offer significant clinical advantage in various hemorrhage areas.
