ABSTRACT
Objective To observe the clinical efficacy of irinotecan combined with capecitabine or tegafur-gimeracil-oteracil potassium in the second-line treatment of advanced colorectal cancer. Methods The clinical data of 19 patients with advanced colorectal cancer who were admitted to the Cancer Hospital of Chinese Academy of Medical Sciences and Peking Union Medical College from October 2014 to December 2017 were retrospectively analyzed, and these patients failed the first-line chemotherapy regimen. All patients were treated with irinotecan plus capecitabine or tegafur-gimeracil-oteracil potassium. The patient's short-term efficacy, adverse reactions, progression-free survival, and overall survival were analyzed. Results After treatment, the efficacy in 18 of the 19 patients with advanced colorectal cancer was evaluable, including partial remission in 3 patients, stable disease in 13 patients, and disease progression in 2 patients. The objective remission rate was 16.7％ (3/18), the disease control rate was 88.9％ (16/18), the median progression-free survival time was 7.6 months, and the median overall survival time was 23.3 months. All of the patients were well tolerated , and the grade 4 adverse reaction was presented as grade 4 neutropenia (1 case), grade 3 leukopenia (2 cases) and thrombocytopenia (1 case), grade 2 diarrhea (1 case), and grade 1 diarrhea (3 cases), and grade 1-2 liver injury (3 cases) and nephrotoxicity (2 cases). Conclusion Irinotecan combined with capecitabine or tegafur-gimeracil-oteracil potassium in the treatment of advanced colorectal cancer is effective and safe, which is worthy of clinical promotion.
ABSTRACT
Objective To evaluate the clinical value and toxicities of docetaxel plus capecitabine in the first-line treatment of metastatic breast cancer (MBC),and compare the outcomes among different molecular subtypes.Methods A total of 108 patients with MBC who received docetaxel plus capecitabine combination treatment between January 1,2012 and December 31,2015 in Bejing Chaoyang District Sanhuan Cancer Hospital were retrospectively analyzed,and 104 cases were available for evaluation.The clinicopathological characteristics,clinical value and toxicities of these patients were evaluated.Results The patients were divided into 3 molecular subtypes,among 104 patients,85 patients in Luminal subtype,14 patients in triple negative breast cancer (TNBC) subtype,and 5 patients in human epidermal growth factor receptor-2 (HER-2) over expression subtype.The treatment achieved objective responses (OR) in 55 patients (52.9％),and the disease control rate (DCR) was 88.5％,including complete response (CR) in 4 patients,partial response (PR) in 51 patients,stable disease (SD) in 37 patients,and progressive disease (PD) in 12 patients.In Luminal subtype,4 patients achieved CR,43 PR,33 SD,and 5 PD.In TNBC subtype,6 patients achieved PR,3 SD,5 PD.In the HER-2 over expression subtype,2 patients achieved PR,1 SD,2 PD.There was no significant difference in the short-term therapeutic effect among 3 molecular subtypes (x2 =4.429,P =0.106).As a result,the progression-free survival (PFS) of the 104 patients was 1.5-121.0 months,and the median PFS was 10.0 months.The median PFS was 11.0 months in Luminal subtype,4.0 months in TNBC subtype and 10.3 months in HER-2 over expression subtype,with a significant difference (x2 =7.510,P =0.006).The most common adverse events were hand-foot syndrome (HFS),nausea or vomiting,neutropenia,anaemia,diarrhea and so on.The incidence of grade 2/3 HFS was 44.2％ (46/104),and the grade 3/4 neutropenia was 39.4％ (41/104).Conclusion The first-line treatment of MBC using docetaxel plus capecitabine is effective,and the toxicities can be tolerable,especially in the Luminal subtype.
