Surgery-alone, preoperative short course, preoperative long course, and post-operative radiotherapy groups were defined. The overall and sitespecific SPM incidence rates were compared among the radiotherapy groups by multivariate Cox regression, taking chemotherapy and comorbidities into account. Sensitivity tests were performed for attained-year adjustment and long-term survivors analysis. RESULTS A total of 28220 patients were analyzed. The 10-year cumulative SPM incidence was 7.8% [95% confidence interval(CI): 7.2%-8.2%] using a competing risk model. The most common sites of SPM were the lung, liver, and prostate. Radiotherapy was not associated with increased SPM risk in multi-variate Cox model(hazard ratio = 1.05, 95%CI: 0.91-1.21, P = 0.494). The SPM hazard remained unchanged in 10-yearsurvivors. In addition, no SPM risk difference was found between the preoperative radiotherapy and postoperative radiotherapy groups.CONCLUSION In this large population-based cohort study, we demonstrated that radiotherapy had no increase in SPM.展开更多

In 2004, a study revealed thatchemoradiotherapy (CRT) resulted in better local control when performedpreoperatively rather than postoperatively, thus neoadjuvant treatment wasestablished as a standard treatment. Subsequently, the Polish study and the Trans-Tasman Radiation Oncology Group showed no statistically significant differencebetween concomitant CRT over 5 wk vs short-course radiotherapy (RT).Therefore, both were established as standard neoadjuvant treatments. Later, theStockholm III study demonstrated that short-course RT had a higher completepathological response than long-course RT. It also showed that a delay betweenRT and surgery presented fewer complications. This opened a window of time toprovide an early and effective systemic treatment to prevent distant metastases.Studies show that short-course RT plus oxaliplatin-based chemotherapy couldachieve this. When comparing this total neoadjuvant treatment (TNT) vsconcomitant CRT, the former showed greater complete pathological response andlower acute toxicity. Studies presented during 2020 have also shown the benefitsof TNT in terms of complete pathological response, as well as disease andmetastasis-free survival. Our review suggests that probably TNT should be thenew standard treatment for these patients. However, we will have to wait for thefull text publications of these studies to confirm this statement.展开更多

Methods: A large-scale, multi-center, double-blinded, and randomized controlled trial was conducted in 18 sentinel hospitals in China from December 2012 to December 2016. A total of 312 MDR-PTB patients were randomly assigned to BFJD Granules or placebo groups(1:1) using a stratified randomization method, which both received the long-course chemotherapy regimen for 18 months(6 Am-Lfx-P-Z-Pto, 12 Lfx-P-Z-Pto). Meanwhile, patients in both groups also received BFJD Granules or placebo twice a day for a total of 18 months, respectively. The primary outcome was cure rate. The secondary outcomes included time to sputum-culture conversion, changes in lung cavities and quality of life(QoL) of patients. Adverse reactions were monitored during and after the trial. Results: A total of 216 cases completed the trial, 111 in the BFJD Granules group and 105 in the placebo group. BFJD Granules, as adjuvant treatment, increased the cure rate by 13.6% at the end of treatment, compared with the placebo(58.4% vs. 44.8%, P=0.02), and accelerated the median time to sputum-culture conversion(5 months vs. 11 months). The cavity closure rate of the BFJD Granules group(50.6%, 43/85) was higher than that of the placebo group(32.1%, 26/81;P=0.02) in patients who completed the treatment. At the end of the intensive treatment, according to the 36-item Short Form, the BFJD Granules significantly improved physical functioning, general health, and vitality of patients relative to the placebo group(all P<0.01). Overall, the death rates in the two groups were not significantly different;5.1%(8/156) in the BFJD Granules group and 2.6%(4/156) in the placebo group. Conclusions: Supplementing BFJD Granules with the long-course chemotherapy regimen significantly increased the cure rate and cavity closure rate, and rapidly improved QoL of patients with MDR-PTB(Registration No. ChiCTR-TRC-12002850)展开更多
