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.

Gastrointestinal stromal tumor(GIST) originates from interstitial cells of Cajal(ICCs). Tyrosine kinase inhibitors(TKI) such as imatinib and sunitinib, are effective agents besides surgery. However some GIST can become primarily or secondarily resistant to those drugs. The difference in gene mutation types and secondary gene mutation is the main cause. When the GIST is proved to be drug resistance, reasonable personal treatment strategies based on individualized medicine should be made to improve outcomes and quality of life.

Objective: To evaluate the safety and efficacy of anlotinib plus irinotecan in the second-line treatment of patients with metastatic colorectal cancer (mCRC). Methods: This prospective phase 1/2 study was conducted in 2 centers in China (Cancer Hospital of Chinese Academy of Medical Sciences and Jiangsu Province Hospital). We enrolled patients with mCRC whose disease had progressed after first-line systemic therapy and had not previously treated with irinotecan to receive anlotinib plus irinotecan. In the phase 1 of the trial, patients received anlotinib (8 mg, 10 mg or 12 mg, po, 2 weeks on/1 week off) in combination with fixed-dose irinotecan (180 mg/m(2), iv, q2w) to define the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D). In the phase 2, patients were treated with the RP2D of anlotinib and irinotecan. The primary endpoints were MTD and objective response rate (ORR). Results: From May 2018 to January 2020, a total of 31 patients with mCRC were enrolled. Anlotinib was well tolerated in combination with irinotecan with no MTD identified in the phase 1, and the RP2D was 12 mg. Thirty patients were evaluable for efficacy analysis. Eight patients achieved partial response, and 21 had stable disease, 1 had progressive disease. The ORR was 25.8% and the disease control rate was 93.5%. With a median follow-up duration of 29.5 months, the median progression-free survival and overall survival were 6.9 months (95% CI: 3.7, 9.3) and 17.6 months (95% CI: 12.4, not evaluated), respectively. The most common grade 3 treatment-related adverse events (≥10%) were neutropenia (25.8%) and diarrhea (16.1%). There was no treatment-related death. Conclusion: The combination of anlotinib and irinotecan has promising anti-tumor activity in the second-line treatment of mCRC with a manageable safety profile.

Sporadic malignant pheochromocytoma, a rare disease with poor prognosis, is always difficult to treat due in part to lack of effective agents. We presented three patients with advanced malignant pheochromocytoma treated by sunitinib, which indicates that sunitinib is an effective agent for this malignancy.

Anlotinib hydrochloride is the only anti-angiogenic, multi-targeted tyrosine kinase inhibitor, which has been approved for non-small cell lung cancer and small cell lung cancer in China. In order to provide guidance for clinical practitioners to use anlotinib hydrochloride safely and efficiently, the Chinese Association for Clinical Oncologists, the Expert Committee of Vascular Targeted Therapy of Chinese Society of Clincal Oncology and the Cancer Targeted Therapy Professional Committee of China Anti-Cancer Association co-organized experts and integrated multiple evidences of Anlotinib Hydrochloride, from both clinical trial, post-marketed clinical data and the associated experiences of experts accumulated in clinical practice, etc. The present consensus covers the clinical data of anlotinib hydrochloride applied in advanced non-small cell lung cancer and small cell lung cancer, and the safety management recommendations.

OBJECTIVETo investigate the efficacy and safety of sunitinib on the management of gastrointestinal stromal tumors (GIST) patients with imatinib resistance.

METHODSClinical data of 48 patients with imatinib-resistant GIST received sunitinib therapy from May 2008 to April 2012 in the Union Hospital of Fujian Medical University were analyzed retrospectively. Eighteen patients received 50 mg/d of sunitinib in a protocol of 4/2 (4 weeks on and 2 weeks off) [50 mg/d (4/2)], and 30 patients received a protocol of 37.5 mg of sunitinib continuous daily dose (37.5 mg/d CDD).

RESULTSThe median duration of sunitinib administration of all the 48 patients was 56 weeks, and the short-term efficacy was evaluated at 24 weeks after the initial treatment according to the Choi criteria. The response rate was 27.1% (13/48), including 1 case with complete response (CR), 12 cases with partial response (PR), and 21 cases with stationary disease (SD). The disease control rate was 70.8% (34/48). The mean follow-up time of 48 patients was 89 weeks. The median progression-free survival (PFS) and overall survival (OS) were 48 weeks and 92 weeks respectively. Stratified analyses indicated that the median PFS of patients previously treated by imatinib 400 mg/d and >400 mg/d were 53 weeks and 35 weeks respectively (P=0.018), and the median OS of these two groups were 157 weeks and 71 weeks respectively (P=0.003). Patients with exon 11 mutations had a significantly shorter OS compared with those with exon 9 mutations (71 weeks vs 157 weeks, P=0.008). Hand-foot syndrome was the most common adverse effect (25/48, 52.1%), followed by nausea (24/48, 50.0%), fatigue (23/48, 47.9%), neutropenia(21/48, 41.7%). The sub-group analysis of two protocols of sunitinib administration showed that the incidence of diarrhea and hand-foot syndrome were higher in 50 mg/d (4/2) group than those in 37.5 mg/d CDD group (P=0.027, P=0.048).

CONCLUSIONSSunitinib is effective for the patients with imatinib-resistant GIST. After 400 mg/d imatinib treatment failure, sunitinib should be prescribed instead of increased dosage of imatinib. Patients with KIT exon 9 mutations present better prognosis than those with KIT exon 11 mutations. The protocol of sunitinib 37.5 mg/d CDD possesses better safety.
