ABSTRACT
Objective To explore the efficacy and toxicities of gemcitabine combined with S-1 in treating locally advanced and metastatic pancreatic ductal adenocarcinoma and prognostic factors. Methods We retrospectively analyzed the clinical data of patients with locally advanced and metastatic pancreatic cancer receiving gemcitabine and S-1 as first-line therapy in the Department of Medical Oncology,Peking Union Medical College Hospital from January 2014 to January 2017.Gemcitabine was administered at a dose of 1000 mg/mover 30 min-utes on days 1 and 8,and oral S-1 at a dose of 40-60 mg twice daily from days 1 to 14,repeated every 3 weeks.All patients received at least two cycles of chemotherapy. Results A total of 60 patients were included,13(22%) achieved partial remission,37(61%) had stable disease,and 10(17%) experienced progressive disease.The median progression-free survival was 7 months(95% CI=6-10 months) and the median overall survival was 12 months(95% CI=9-20 months).Both univariate and multivariate analyses of prognostic factors showed primary resection was significant in predicting shorter progression-free survival and lung metastasis was significant for shorter overall survival.The most common grade 3-4 toxicities were neutropenia(27%) and leukopenia(18%). Conclusion Gemcitabine combined with S-1 is an effective regimen with manageable toxicities in the treatment of advanced pancreatic cancer and can be used as first-line therapy.
ABSTRACT
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 investigate the clinical treatment modality and prognosis of small cell lung cancer(SCLC).</p><p><b>METHOD</b>We retrospectively analyzed the clinical data of 77 SCLC patients who were admitted to our department after 2002.</p><p><b>RESULTS</b>The disease was limited in 43 patients and extensive in 34 patients. For patients with limited SCLC, the 1-year, 2-year, and 5-year survival rate was 80%, 56%, and 21%, respectively. Four patients who had undergone surgical resection were all alive. Among patients who underwent adjuvant chemotherapy followed by radiotherapy, salvage chemotherapy, and salvage chemotherapy followed by radiotherapy, the median of survival period was 51 months, 12 months, and 28 months, respectively. For patients with extensive SCLC, the 1-year and 2-year survival rate was 56% and 25%, respectively. The median of survival period was 14.3 months. Stage was an independent factor in multifactor COX regression. Monofactor COX regression showed that radiotherapy and resection were factors correlated with survival. Brain metastasis had no impact on survival.</p><p><b>CONCLUSIONS</b>Chemotherapy followed by radiotherapy is preferred for limited SCLC, while surgical resection remains questionable for early-stage patients. For extensive SCLC, multi-line chemotherapy may be helpful to improve the overall survival. Stage is an independent factor for predicting the prognosis.</p>
