Survival curves were constructed by the Kaplan-Meier method, and Cox regression models were used to identify independent prognostic factors.Results: Of the included patients, 1,375(53.5%) were male, and the patient age range was 18 to 95(median, 58)years. The tumors were mostly found in the stomach(64.5%), small intestine(25.1%) and colorectal region(5.1%).At the time of diagnosis, the median tumor size was 4.0(range: 0.1–55.0) cm, and the median mitotic index per 50 high power fields(HPFs) was 3(range: 0–254). Of the 2,168 resected patients, 2,009(92.7%) received curative resection. According to the modified National Institutes of Health(NIH) classification, 21.9%, 28.9%, 14.1% and35.1% were very low-, low-, intermediate-and high-risk tumors, respectively. The rate of positivity was 96.4% for c-Kit, 87.1% for CD34, 96.9% for delay of germination 1(DOG-1), 8.0% for S-100, 31.0% for smooth muscle actin(SMA) and 5.1% for desmin. However, the prognostic value of each was limited. Multivariate analysis showed that age, tumor size, mitotic index, tumor site, occurrence of curative resection and postoperative imatinib were independent prognostic factors. Furthermore, we found that high-risk patients benefited significantly from postoperative imatinib(P〈0.001), whereas intermediate-risk patients did not(P=0.954).Conclusions: Age, tumor size, mitotic index, tumor site, occurrence of curative resection and postoperative imatinib were independent prognostic factors in patients with GISTs. Moreover, determining whether intermediate-risk patients can benefit from adjuvant imatinib would be of considerable interest in future studies.展开更多

Methods: We analyzed the outcome of 451 HCC patients underwent liver resection, transcatheter arterial chemoembolization and radiofrequency ablation, respectively. Then risk factors for aged and younger patients' survival were evaluated by multivariate analysis, respectively. Results: The patients who were older lhan 55 years old were defined as the older group. The overall survival for aged patients was significantly worse than those younger patients. The younger patients had similar liver fhnctional reserve but more aggressive tumor Paclors than aged patients. Cox regression analysis showed that tile elevated levels ofaspartate aminotransferase (AST) (Waldx2= 3.963, P = 0.047, hazard ratio [HR] -1.453, 95% confidence interval [CI]: 1.006-2.098), lower albumin (Wald X2 = 12.213, P 〈 0.001, HR 1.982, q5% CI: 1.351 2.910), tumor size (Wald X2 = 8.179, P- 0,004, HR - 1.841,95% CI: 1.212-2.797), and higher alpha-fetoprotein level (Wald X2=4.044, P = 0.044, HR = 1,465, 95% (CI: 1.010 2.126) were independent prognostic factors for aged patients, while only elevated levelsofAST(WaldZ= 14.491,P〈0.001,HR 2.285, 95%CI: 1.493-3.496)andtumorsize(WaldX2= 21.662, P〈0.001,HR= 2.928, 95% CI: 1.863-4.604) were independent prognostic factors for younger patients. Conclusions: Age is a risk factor to determine the prognosis of patients with HCC. Aged patients who have good liver lhnctional reserve are still encouraged to receive curative therapy.展开更多
