Objective:To explore the clinicopathological characteristics and prognosis of patients with ovarian metastases from colorectal cancer.Methods:A total of 122 female patients with ovarian metastases from colorectal cancer underwent treatment in Cancer Hospital, Chinese Academy of Medical Sciences between 2010 and 2015 were recruited. The clinicopathological features, treatment details and survival data of these patients were retrospectively analyzed. Kaplan-Maier method was used for survival analysis, log rank test and Cox proportional hazards model were used for prognostic factor analysis.Results:The median overall survival (OS) was 19.7 months. The 1-year, 3-years and 5-years OS rates were 72.1%, 24.7% and 9.9%, respectively. A total of 99 (81.1%) patients underwent oophorectomy. The median OS of patients who underwent oophorectomy was 21.9 months, significantly longer than 10.3 months of patients without oophorectomy ( P<0.01). Ovary as the only site of metastasis, primary tumor resection, and oophorectomy were associated with improved survival (all P<0.01). Primary tumor resection and oophorectomy were independent prognostic factors for OS (both P<0.01). Conclusion:Patients with ovarian metastases from colorectal cancer might acquire a survival benefit from surgical resection of the primary tumor and ovaries.

Objective:Anlotinib is an oral multi-target tyrosine kinase inhibitor (TKI) with dual effects of anti-proliferation and anti-angiogenesis. Phase Ⅰ clinical trials showed anlotinib was well tolerated and had therapeutic effects on a variety of tumors. The aim of this study is to explore the safety and efficacy of anlotinib in the treatment of metastatic renal cell carcinoma.Methods:Between January 2014 and November 2015, a single-center data was obtained from a phase Ⅱ clinical study of anlotinib versus sunitinib on advanced renal cell carcinoma and a phase Ⅱ clinical study of anlotinib on advanced renal cell carcinoma which failed to respond to TKI treatment. Kaplan-Meier method was used for survival analysis, while Log-rank test was used to compare the survival rates.Results:A total of 36 patients with advanced renal cell carcinoma were enrolled in this study, including 19 patients without any target drug treatment, 12 patients with sunitinib treatment and 5 patients with sorafenib treatment. The median number of treatment cycle was 16. Partial response (PR) was obtained in 11 patients (30.6%) and stable disease (SD) was obtained in 24 patients (66.7%). The disease control rate (DCR) was 97.2%. The median progression free survival (PFS) was 12.6 months, the 1-year survival rate was 80.6%, and the median survival time was 22.2 months. Up to the follow-up deadline, 3 patients still received treatment, the PFSs were 52.6 months, 65.0 months, and 66.7 months. The most common treatment-related adverse events of grade 3 or 4 included hypertension (19.4%), hand-foot skin reaction (11.1%), proteinuria (5.6%) and anemia (5.6%).Conclusions:Anlotinib shows good anti-tumor activity and is generally well-tolerated in the treatment of advanced renal cell carcinoma. The adverse reactions of anlotinib are milder than sunitinib or pazopanib.

Objective: To investigate the effect of tumor deposits (TD) on the prognosis of patients with stage III colon cancer, and to explore whether TD number included into regional lymph node count can predict the prognosis more accurately. Methods: A retrospective cohort study was carried out. Case inclusion criteria: (1) primary colon cancer; (2) undergoing colon cancer radical operation; (3) definite pathological diagnosis; (4) colon cancer stage III according to AJCC 8th edition; (5) complete follow-up data; (6) without preoperative neoadjuvant treatment. Clinicopathological data of 296 patients undergoing colon cancer radical operation from January 2005 to December 2008 in the Cancer Hospital of Chinese Academy of Medical Sciences were retrospectively collected. The effect of TD and its amount on the prognosis was evaluated. Colon cancer TNM staging method based on the 8th edition of AJCC was compared with the modified TNM staging (mTNM) adjusted by the number of TD. The differences of the disease-free survival (DFS) and overall survival (OS) between groups were also examined. The Kaplan-Meier curve was used to analyze the survival, and prognostic factors were analyzed by Cox univariate and multivariate analyses. Results: Among 296 patients with stage III colon cancer, 78 patients had TD. The median number of TD was 2 (1-10). Tumor T stage, N stage, vascular tumor thrombus and preoperative carcinoembryonic antigen (CEA) were associated with TD in patients with colon cancer (all P<0.05). The right hemicolon appears likely to have TD than left hemicolon, but the difference was not statistically significant (P=0.059). The median follow-up of the whole group was 71 (6-102) months. During the follow-up period, 129 patients (43.6%) had recurrence or metastasis, and 111 patients died (37.5%). The 5-year DFS in TD group was 44.9%, which was lower than that in the non-TD group (60.6%), with statistically significant difference (P=0.003). The 5-year OS in TD group was 50.0%, which was also lower than 67.0% in the non-TD group, and the difference was statistically significant (P=0.002). According to TD number, patients were divided into 3 groups: 1 TD (25 cases), 2-3 TD (32 cases), ≥4 TD (21 cases). The 5-year DFS in these 3 groups was 68%, 56.3%, and 0, respectively (P<0.001), and 5-year OS was 76%, 59.4%, and 4.8% respectively (P<0.001). Univariate analysis showed that TD presence (95% CI: 1.234-2.694, P=0.003) and TD number (95% CI: 3.531-14.138, P<0.001) were associated with the prognosis of patients with stage III colon cancer. At the same time, age, tumor N stage, tumor location, chemotherapy, and preoperative CEA elevation were also associated with the prognosis of stage III colon cancer patients (all P<0.05). Multivariate analysis revealed that TD presence (HR=1.957, 95%CI: 1.269-3.017, P=0.002) and TD number (HR=8.020, 95% CI: 3.414-18.842, P<0.001) were still independent risk factors for the prognosis of patients with stage III colon cancer.According to the TD number counted as metastatic lymph nodes, in 78 patients with TD, 24 patients were upstaged in N stage, and 16 patients upstaged from TNM stage IIIB to stage IIIC. For 16 stage IIIB cases with staging modification, 30 unadjusted stage IIIB cases with TD, and 148 stage IIIB cases without TD, the 5-year OS was 37.5%, 73.3% and 76.4%, respectively with significant difference (P<0.001). However, for 16 patients adjusted as stage IIIC (mTNM), 32 patients with unchanged stage IIIC with TD (TNM, AJCC 8th edition), and 63 stage IIIC cases without TD, the 5-year OS was 37.5%, 36.4%, and 41.3%, respectively without significant difference (P=0.707). Conclusions TD presence and TD number are independent risk factors for prognosis of stage III colon cancerpatients. TNM staging evaluation with lymph node number including TD number can predict the prognosis of patients more accurately.

Objective Vascular endothelial growth factor receptor?tyrosine kinase inhibitors (VEGFR?TKIs) are widely used for the treatment of metastatic renal cell carcinoma (mRCC). The aim of this study was to investigate the association between treatment?related hypertension and the therapeutic efficacy of VEGFR?TKIs. Methods Clinical data of 155 mRCC patients treated with VEGFR?TKIs at the Cancer Hospital of Chinese Academy of Medical Sciences from 2006 to 2014 were retrospectively analyzed. All patients received first?line TKI therapy. Among them, 69 patients were treated with sunitinib, 14 cases with pazopanib, and 51 cases with fazotinib. Kaplan?Meier curves were used to evaluate the survival of the patients. Results The median survival for the whole group ( n=155) was 36. 2 months. Among the 98 (63.2%) patients who developed hypertension, 9 patients (5.8%) were evaluated as gradeⅠ, 54 (34.8%) as grade Ⅱ and 35 (22.6%) as gradeⅢ, and there was no patient with gradeⅣhypertension. The occurrence of TKI?related hypertension was correlated with age and MSKCC score (P<0.05), while not significantly correlated with gender, nephrectomy, T stage, number of metastases, lung metastasis or sunitinib treatment (P>0.05 for all). For the whole group (n=155), the therapeutic efficacy rate was 43.2% (67/155), the median progression?free survival (PFS) was 12.0 months, and the median overall survival (OS) was 36.2 months. The response rate (RR) was 26.3% (15/57) in patients with normal blood pressure and 53.1%(52/98) in patients with hypertension (P=0.001). The median PFS was 7.1 months in the cases with normal blood pressure and 13.8 months in patients with hypertension (P=0.032). The response rates were 33.3% (3/9), 51.9% (28/54) and 60.0% (21/35) in patients with grade Ⅰ, Ⅱ and Ⅲ hypertension (P=0.006). The median PFS was 7.1, 9.7, and 12.0 and 19.5 months in patients with normal blood pressure, and patients with grade Ⅰ, Ⅱ and Ⅲ hypertension, respectively (P=0.039). Both univariant and multivariant analyses indicated that treatment?related hypertension is an important predictive factor for the efficacy of VEGFR?TKIs therapy. Conclusions Hypertension might be an effective predictive factor for efficacy of VEGFR?TKIs therapy in mRCC patients. Large?sample studies are warranted to further prove these results.

OBJECTIVETo analyze the characteristics of recurrence in gastric cancer patients after radical gastrectomy and adjuvant chemotherapy.

METHODSThe clinicopathological data of 110 gastric cancer patients who developed recurrence or second primary malignancies after radical gastrectomy and adjuvant chemotherapy with FOLFOX4 regimen or docetaxel plus FOLFOX4 regimen were analyzed retrospectively.

RESULTSThe median time to recurrence was 13.9 months (range, 1.7 to 63.1 months), and the median overall survival was 27.4 months (range, 6.9 to 90.7 months) in the whole group. The median survival time after recurrence was 10.1 months (range, 0.3 to 73.9 months). 82 (74.5%) patients had recurrence within 2 years after gastrectomy. The modes of surgical procedure and lymph node dissection influenced significantly on the time to recurrence (P<0.05 for both). Among the 110 patients with recurrence, 46 (41.8%) patients had peritoneal metastases, 33 (30.0%) had hematogenous metastases and 32 (29.1%) had locoregional lymph node metastases. Single, double, triple and quatro recurrences were observed at the first time of relapse in 78 (70.9%), 21(19.1%), 9(8.2%) and 2 cases (1.8%), respectively. Patients who developed simultaneous quatro recurrence had the poorest prognosis with a median overall survival of 15.2 months, significantly shorter than that of patients with single recurrence (31.8 months, P=0.003). Patients with peritoneal recurrence died most quickly ( mean 5.6 months), and patients with surgical field recurrence alone survived longest (mean 17.1 months).

CONCLUSIONSPeritoneal, hematogenous and locoregional lymph node metastases are the most frequent recurrences after radical gastrectomy and adjuvant chemotherapy in patients with gastric cancer. Single recurrence occurred in most patients at the first relapse. Combination with other adjuvant treatments should be considered besides adjuvant chemotherapy in gastric cancer patients after radical gastrectomy.
