Objective: To investigate the clinical features of patients with cardiac metastases from digestive system tumors. Methods: This retrospective study collected and analyzed the medical records of patients with cardiac metastases from digestive system tumors who received treatments in the Cancer Hospital, Chinese Academy of Medical Sciences between January 1999 and January 2021. Kaplan-Meier method was used for survival analysis. Results: A total of 19 patients were identified. The primary tumors were esophageal squamous cell carcinoma (n=7), gastric or gastroesophageal junction adenocarcinoma (n=6), hepatobiliary cancers (n=3) and colorectal cancers (n=3). 16 patients had pericardial metastases, 2 patients had right atrium metastases, and 1 patient had left ventricle metastasis. The most common symptom was dyspnea, which was present in 8 cases. 7 patients received locoregional treatment, while 11 patients underwent systemic therapies. The median overall survival from diagnosis of primary cancer was 31.4 months, and the median overall survival time from diagnosis of cardiac metastasis was 4.7 months. Conclusion: Cardiac metastasis from digestive system tumors is associated with low incidence and a poor prognosis. Systemic treatment remains the cornerstone of management, while novel anti-tumor drugs may improve therapeutic efficacy.

Objective: To explore the safety and effectiveness of stereotactic body radiation therapy (SBRT) for oligometastases from colorectal cancer (CRC). Methods: This is a prospective, single-arm phase Ⅱ trial. Patients who had histologically proven CRC, 1 to 5 detectable liver or lung metastatic lesions with maximum diameter of any metastases ≤5 cm were eligible. SBRT was delivered to all lesions. The primary endpoint was 3-year local control (LC). The secondary endpoints were treatment-related acute toxicities of grade 3 and above, 1-year and 3-year overall survival (OS) and progression free survival (PFS). Survival analysis was performed using the Kaplan-Meier method and Log rank test. Results: Petients from 2016 to 2019 who were treated in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Forty-eight patients with 60 lesions were enrolled, including 37 liver lesions and 23 lung lesions. Forty-six patients had 1 or 2 lesions, with median diameter of 1.3 cm, the median biologically effective dose (BED(10)) was 100.0 Gy. The median follow-up was 19.5 months for all lesions. Twenty-five lesions developed local failure, the median local progression free survival was 15 months. The 1-year LC, OS and PFS was 70.2% (95% CI, 63.7%~76.7%), 89.0% (95% CI, 84.3%~93.7%) and 40.4% (95%CI, 33.0%~47.8%). The univariate analysis revealed that planning target volume (PTV) and total dose were independent prognostic factors of LC (P<0.05). For liver and lung lesions, the 1-year LC, OS and PFS was 58.7% and 89.4% (P=0.015), 89.3% and 86.5% (P=0.732), 30.5% and 65.6% (P=0.024), respectively. No patients developed acute toxicity of grade 3 and above. Conclusion: SBRT is safe and effective treatment method for oligometastases from CRC under precise respiratory motion management and robust quality assurance.

Objective:To study the efficacy of different systemic chemotherapy regimens as first-line and second-line therapy and to determine the prognostic factors for patients with advanced biliary tract cancer.Methods:The clinical data of patients with advanced biliary tract cancer who underwent systemic chemotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from January 2011 to December 2018 were studied. The efficacy of chemotherapy on objective response rate (ORR) and disease control rate (DCR) were evaluated. Potential prognostic factors for survival were studied using the Cox proportional hazards models.Results:Of 151 patients enrolled into this study, there were 75 males and 76 females, with ages ranging from 31 to 77 years (median 58 years). Two treatment protocols were used: (1) 104 patients received a gemcitabine-based regimen (combined with platinums or fluorouracils) or a combination of platinums and fluorouracils, while (2) 47 patients received a combination of albumin-bound paclitaxel and S-1. The corresponding ORR for each group were 15.4%(16/104) and 27.6%(13/47), respectively, and the DCR were 65.4%(68/104) and 72.3%(34/47), respectively. Of 58 evaluable patients who received chemotherapy as a second-line therapy, 31 patients received the regimen containing gemcitabine, platinums or fluorouracils with an ORR of 3.2% (1/31) and a DCR of 35.5%(11/31); a total of 18 patients received the taxanes-based regimen with an ORR of 11.1%(2/18) and a DCR of 38.9%(7/18); 9 patients received the irinotecan-based regimen with an ORR of 22.2%(2/9) and a DCR of 44.4%(4/9). Univariate analysis showed positive liver metastasis and elevated carbohydrate antigen (CA)19-9 level to be significantly correlated with worse survival outcomes ( HR=1.540, 95% CI: 1.019-2.328, P=0.040 and HR=1.892, 95% CI: 1.123-3.188, P=0.017). Conclusion:For patients with advanced biliary tract cancer, in addition to the conventional regimens containing gemcitabine, platinums and fluorouracils, the combination of albumin-bound paclitaxel and S-1 was shown to be an effective chemotherapeutic regimen for these patients. Second-line chemotherapy was insufficient and ineffective, and an irinotecan-based regimen deserves to be further investigated. Liver metastasis and elevated CA19-9 level were worse prognosis after chemotherapy for patients with advanced biliary tract cancer.

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.
