RESUMEN
Objective:To compare the efficacy and safety of pegylated liposomal Doxorubicin(PLD)and Epirubicin(EPI)as first-line chemotherapy for diffuse large B-cell lymphoma(DLBCL).Methods:Clinical data of DLBCL patients treated at Zhejiang Cancer Hospital from March 2013 to April 2018 were retrospectively collected.A total of 411 patients who had received first-line chemotherapy were included.Based on age, sex, Ann Arbor staging and other parameters and using the PSM method for 1∶1 matching, 151 patients were assigned into each of the PLD group and the EPI group.Efficacy and adverse events were compared between the PLD group and the EPI group.All patients were followed up for 3 years after treatment to monitor survival.Results:The complete response(CR)rate in the PLD group was 81.5%, and the CR rate in the EPI group was 72.2%.The objective response rate(ORR)of the PLD group was 98%, and the ORR of the EPI group was 96.7%.There was no significant difference in CR rate( χ2=0.478, P=0.489)or ORR between the two groups( χ2=0.007, P=0.934). In the PLD group, myelosuppression occurred in 25 cases(16.6%)and cardiotoxicity-related events in 21 cases(13.9%); in the EPI group, there were 24 cases(15.9%)of myelosuppression and the same number of cases of cardiotoxicity-related events, and there were no significant differences in myelosuppression( χ2=0.018, P=0.895)or cardiotoxicity( χ2=0.174, P=0.677)between the two groups.During the 3-year follow-up, the progression free survival(PFS)rates of the PLD group and the EPI group were 79.1% and 69.6%, respectively, with a statistically significant difference between the two groups( χ2=3.930, P=0.047). Both the PLD group and the EPI group had a 3-year OS rate of 85.2%, with no statistically significant difference between the two groups( χ2=0.402, P=0.538). Conclusions:The 3-year progression-free survival of DLBCL patients with PLD as first-line chemotherapy is significantly better than with EPI, and the 3-year overall survival, short-term efficacy and myelosuppression are comparable to those with EPI.
RESUMEN
Objective To compare the efficacy of trimodality therapy and chemoradiation therapy (CRT) alone in patients with locally advanced resectable esophageal squamous cell carcinoma (SCC).Methods A total of 124 cases with locally advanced resectable esophageal SCC were retrospectively analyzed and classified into 2 groups.Fifty-four cases in trimodality group were treated with surgery and preoperative chemoradiation,while 70 cases in CRT alone group only received radiation and chemotherapy.Local tumor control,3-year survival and treatment-related mortality were assessed.Results The local recurrent rate of the resected patients was 18.5％ in trimodality group and 35.7％ in CRT alone group,respectively(x2 =4.445,P ＜ 0.05).The 3-year progression-free survival (PFS) was 65.3％ (95％ CI 50.7-80.5) in trimodality group and31.9％ (95％CI 19.6-44.2) in CRT alone group (P＜0.05),while the overall survival (OS) 66.3％ (95％ CI43.0-89.6) and 34.4％ (95％ CI 21.1-47.7),respectively(P ＜ 0.05).Treatment-related mortality was 1.9％ in trimodality group and 2.9％ in CRT alone group (P ＞ 0.05).For CRT alone group,the sub-group analysis showed that there was no statistically significant difference in the 3-year OS between patients who received 50-50.4 Gy and those who received the dose over 50.4 Gy (39.9％ 95％ CI 18.5-61.3 vs.31.5％ 95％ CI 14.8-48.2,P ＞0.05).Conclusions Compared with CRT alone,trimodality therapy showed the superior local control,PFS and OS,with similar treatment-related mortality in the treatment of patients with SCC of esophagus.The role of surgery could not be replaced by CRT alone even with the augment of radiation dose.
RESUMEN
At present,the treatment for non-small cell lung cancer (NSCLC) consists of surgery,radiation,chemotherapy,targeted therapy,etc.The epidermal growth factor receptor (EGFR) gene mutation opened a new era of individualized treatment.Multidisciplinary treatment come next after the combination of different treatment approaches,and the modality of targeted therapy like epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) in combination with radiation was included.The present work reviews clinical progress for the EGFR-TKI combined with radiotherapy in advanced NSCLC.
