Difference of left ventricular segmental longitudinal strain in patients with lymphoma receiving anthracycline detected by three dimensional speckle tracking imaging / 中华超声影像学杂志

Objective@#To detect the changes of systolic function of left ventricle in patients with lymphoma receiving anthracycline by three dimensional speckle tracking imaging(3D-STI).@*Methods@#Thirty patients with newly diagnosed diffused large B-cell lymphoma who had received R-CHOP chemotherapy were enrolled. Left ventricular global longitudinal strain (GLS), global circumferential strain(GCS) and longitudinal strain(LS) on different left ventricular segments were measured by 3D-STI at baseline, after the completion of 2 cycles and 4 cycles of the regimen respectively.@*Results@#Compared with baseline, GLS reduced significantly after four cycles of anthracycline chemotherapy(P=0.002). Analysis of LS on different segments of the left ventricle shows: after 2 cycles of anthracycline chemotherapy, LS only on apical septum was significantly decreased(P=0.019). After 4 cycles of treatment, LS on mid anterior, mid anteroseptal, mid inferoseptal, mid anterolateral, apical anterior, apical septal walls and apex worsened (t=3.321, P=0.002; t=2.497, P=0.018; t=2.387, P=0.024; t=2.096, P=0.045; t=4.015, P=0.000; t=4.064, P=0.000; t=3.370, P=0.002, respectively).@*Conclusions@#LS deterioration emerges on some left ventricular walls in patients with lymphma underwent chemotheapy based on anthracycline in early stage of the remedy, especially on apex and mid segments. LS on apical septum manifests firstly. The segmental LS index maybe expected to be valuable for monitoring of early cardiotoxicity of antharcycline.

Efficacy and safety of rituximab combined with CHOP or combined with dose fractionated CHOP in the treatment of primary gastric diffuse large B cell lymphoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>The aim of this study was to compare the safety and efficacy profiles of R-CHOP and R-fCHOP regimes in the treatment of primary gastric diffuse large B cell lymphoma (PG-DLBCL).</p><p><b>METHODS</b>Data of PG-DLBCL patients admitted in our hospital from March 2010 to March 2014 were collected retrospectively. Differences in gastrointestinal bleeding and perforation between the R-CHOP group and R-fCHOP group were compared. The influence of the gastrointestinal complication on subsequent treatment was also analyzed. Treatment outcome of the two groups was also compared.</p><p><b>RESULTS</b>A total of 50 patients were included in this retrospective study. Forty of them were in the R-CHOP group, another ten were in the R-fCHOP group. Patients in the R-fCHOP group had a higher rate of Lugano late stage disease, and a relatively high rate of a deeper/larger ulcer. Fence occult blood test (FOBT) was positive in one (10.0%) patient in the R-fCHOP group, and 11 (31.4%) patients in the R-CHOP group, among them one had hematemesis and had to give up the subsequent chemotherapy. No perforation was observed in both groups. The response rate (RR) was 92.5% in the R-CHOP group and 90.0% in the R-fCHOP group (P > 0.05). The PFS was also comparable between the two groups (P > 0.05).</p><p><b>CONCLUSIONS</b>R-fCHOP regimen has a good safety profile in patients with Lugano late stage and deep/large ulcers, who are of high risk of gastrointestinal bleeding or perforation, and also has a comparable efficacy profile when compared with the R-CHOP regimen in short-term follow-up.</p>

Polymorphisms of DNA repair genes XRCC1 and susceptibility to non-Hodgkin lymphoma / 白血病·淋巴瘤

Objective To investigate the correlation between XRCC1 R280H,XRCCl TSS+29C/T genetic polymorphisma and susceptibility to non-Hodgkin lymphoma (NHL). Methods The MassARRAY method was applied to detect the DNA repair gene XRCC1 genetic polymorphisms in 73 cases of NHL and 540 cases of normal healthy controls. Chi-square test was performed to calculate the adjusted odds ratios (OR) and 95% confidence intervals (CI). Results For XRCCl R280H genotypes, there was a significant difference between frequencies of the G and A among patients and controls (P=0.001). However, XRCCl TSS+29C/T genotypes had no statistical difference as for the T and C frequencies between patients and controls (P = 0.383). The frequency of XRCCI R280H with at least one A genotype was lower in the NHL cases than in controls, indicating a decreased risk for NHL development (OR=0.309, 95 % CI =0.168-0.567), comparing with GG genotype. In XRCC1 TSS+29C/T genotypes, the frequeney of TC and CC genotype was higher in NHL cases than in controls and associated with an increased risk of NHL development (P=0.472, OR =1.262, 95 % CI =0.669-2.379). Conclusion DNA repair XRCCl gene possesses significant correlation with NHL.

A REPORT OF 25 CASES OF TUMORS OF BRAIN STEM / 中国医师进修杂志

Objective　To evaluate the methods of surgical treatment for tumors of brain stem and their curative effects. Methods: 25 cases of tumors of brain stem were analysed retrospectively. Results: There were 18 cases of astrocytomas, 2 cases of cavernous angioma, 1 cases of hemangioblastoma, 1 cases of dermoid cyst, 1 cases of syringopontia, 1 cases of inflammatory granuloma accompanied with hecrosis and 1 cases of AVM of brain stem in 25 cases. Four patients died after operation. Conclusion: Extrinsic tumors of brain stem could be resected totally or subtotally, resulting in good outcome.
