Résumé
Objective To explore the efficiency of sunitinib in Chinese pancreatic neuroendocrine tumors (pNET) patients. Methods Advanced pNET patients who had accepted sunitinib treatment in the oncology department of PUMC Hospital from January 2009 to June 2015 after disease progression were enrolled in this study. Data collection included clinicopathological characteristics,medical therapies and outcomes. Results Eighteen pNET patients were collected. The overall response rate (ORR) was 27.7% and the disease control rate (DCR) was 83.3%. Nine patients received sunitinib as the first-line therapy and 9 as the second/post-second line. The median progression-free survival (mPFs)(12 month vs. 12 month;HR:0.92,95%CI:0.31-2.75,P=0.88),ORR (22.2% vs.33.3%;Χ(2)=0.055,P=0.98),and DCR (88.9% vs.77.8%;Χ(2)=0.4,P=0.98)showed no significant difference between first-line therapy and post-second line therapy. The mPFS of Ki-67≥10% and Ki-67<10% group patients was not significantly different (8 months vs. 13 months;HR:1.13,95% CI:0.34-3.77,P=0.845). The commonly reported adverse events included bone marrow suppression,diarrhea,roteinuria,hypertension,and rash. Conclusions First-line or second/post-second line sunitinib treatment has certain antitumor activity in Chinese patients with advanced pNET. The efficiency and commonly reported adverse events of Sunitinib are consistent with the known Western data.

<p><b>OBJECTIVE</b>To detect KLF17 expression in colorectal carcinoma (CRC) and to evaluate its effect on the prognosis of colorectal carcinoma.</p><p><b>METHODS</b>Immunohistochemistry was performed to detect the expression of KLF17 in CRC and matched pericarcinous tissue,and the relationship between KLF17 expression and disease-free survival (DFS) was analyzed.</p><p><b>RESULTS</b>Of 73 CRC patients, KLF17 expression was positive in 32 patients and negative in 41 patients. KLF17 expression rate was significantly lower in CRC tissue than in pericarcinous tissue (χ(2)=12.418, P=0.001). The DFS of KLF17-positive stage III colon cancer patients was (56.3±7.2) months (95% CI: 42-70 months), which was significantly longer than that [(32.3±5.5) months (95% CI: 22-43 months)] of KLF17-negative patients (P=0.039).</p><p><b>CONCLUSION</b>KLF17 expression decreases in CRC tissue, and a positivie KLF17 expression predicts a better prognosis in stage III CRC patients.</p>

The incidence of cancer increases with age and most elderly patients will choose chemotherapy, and the complications of cytotoxic chemotherapy will be more common in these patients. Therefore, it is particularly important to predict the chemotherapy toxicity for the elderly patients. This review article summarizes the recent chemotherapy risk assessment tools for the elderly patients.
