Comparison of the therapeutic effects of paclitaxel liposome-5-Fu versus paclitaxel-5-Fu on 67 patients with advanced gastric cancer / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To explore the efficacy, time to disease progression (TTP), overall survival (OS) and toxicity of paclitaxel liposome versus paclitaxel combined with 5-fluorouracil (5-Fu) for patients with advanced gastric cancer.</p><p><b>METHODS</b>The therapeutic efficacy of chemotherapy with either of the two regimens for 67 cases of naïve advanced gastric cancer was analyzed. Among them, 31 patients in the paclitaxel liposome-5-Fu group received paclitaxel liposome 175 mg/m(2) d1, CF 200 mg/m(2) d1, 5-Fu 2.6 g/m(2) civ. 46 hours, 21 days as one cycle, and 34 patients in the paclitaxel-5-Fu group received paclitaxel 175 mg/m(2) d1, CF 200 mg/m(2) d1, 5-Fu 2.6 g/m(2) civ. 46 hours, 21 days as one cycle.</p><p><b>RESULTS</b>The objective response rate was 54.8% in the paclitaxel liposome group and 44.1% in the paclitaxel group (P = 0.388). The median time to progression was 5.10 months vs. 5.20 months (P = 0.266) and the median survival time was 10.07 months vs. 8.97 months (P = 0.186). The most frequent side-effects were nausea, vomit and hematological toxicities. The rates of grade III-IV nausea and vomit were 16.1% and 50.0% (P = 0.038), muscle and joint pain were 9.7% and 29.4% (P = 0.047).</p><p><b>CONCLUSION</b>Both regimens are effective in the treatment of advanced gastric cancer. However, less adverse effects occur in the paclitaxel liposome group.</p>

The semiquantitative three-phase bone scintigraphy on hemiplegic patients with earlier complex regional pain syndrome / 中华核医学杂志

Objective To investigate the difference between the early phases and delay phase of three-phase bone scintigraphy on hemiplegic patients with earlier complex regional pain syndrome (CRPS).Methods Twenty-nine stroke patients with hemiplegia complicating CRPS received three-phase bone scintigraphy after intravenous injection of 99Tcm-methylene diphosphonate (MDP). The region of interest (ROI)technique was used to obtain the radioactive counts of involved joints and contralateral sites on wrists,metacarpophalangeal,proximal interphalangeal and distal interphalangeal joints. The total counts of these four sites in each patient were then obtained and the total uptake ratios of involved joints/contralateral joints for each phase were calculated to compare the difference among the three phases. Wilcoxon test and ANOVA were used in data analyses. Results The involved joints of hemiplegic side displayed higher tracer uptake.There were significant differences of the radioactive counts between involved joints and uninvolved ones in the perfusion,pool and delay phase (Wilcoxon test,Z:-4.73 to -2.10,P＜0.05). There was no significant difference of total uptake ratios of involved joints/contralateral joints among the three phases ( ANOVA,F = 0. 807,P ＞ 0.05 ). Conclusions Due to higher bone seeking agent accumulation on three-phase bone scintigraphy,both early phases and delay phase imaging showed similar value in stroke patients with hemiplegia complicating earlier CRPS.
