ObjectiveTo investigate the quality of life (QOL) and its influencing factors of patients with human epidermal growth factor receptor 2 (HER2) positive breast cancer returning to social life after treatment.MethodsFunctional assessment of cancer therapy-breast scale (FACT-B Scale) was adopted to investigate the QOL of the HER2 positive breast cancer survivors, who were admitted and treated during January 2015 and October 2019 in Fujian Provincial Hospital. The demographic, social and economic data, as well as the clinical information of the responded survivors were collected. Logistic regression model was adopted to analyze factors associated with the QOL of the responded survivors.ResultsA total of 117 responded survivors were included. The median of the FACT-B scale was 106.0 (91.0, 121.3) points out of 148 points (71.6%). With the control of the demographic, social and economic status of the responded survivors, as well as the time from diagnosis and treatment to responding to the follow-up, we found that "having other chronic conditions" was the risk factor for the HER2 positive breast cancer survivors to have higher QOL in the social life after treatment (OR=4.17, 95%CI 1.33 to 15.37, P=0.01).ConclusionsThe overall QOL of the HER2 positive breast cancer survivors in the social life after treatment was low. "Having other chronic conditions" was the risk factor for the HER2 positive breast cancer survivors to have higher QOL in the social life after treatment.
ObjectiveTo systematically evaluate the correlation of amplification of human epidermal growth factor receptor 2 (HER2) with the clinicopathological characteristics and prognosis of colorectal cancer patients.MethodsPubMed, EMbase, Cochrane Library, Chinese Biomedical Literature Database (CBM), Wanfang, and other databases were searched, and cohort studies focused on the relationship between HER2 amplification and clinicopathological characteristics and prognosis of colorectal cancer patients were included. The retrieval time limit was from October 2020, and RevMan 5.4 software was used for meta-analysis.ResultsA total of 9 studies (11 cohorts) were included for meta-analysis of 7 209 patients with colorectal cancer. Results of the meta-analysis showed that HER2 amplification was not associated with overall survival [HR=1.10, 95%CI (0.98, 1.24), P=0.11]. HER2 amplification was not correlated with gender [OR=0.98, 95%C1 (0.74, 1.31), P=0.90] and tumor differentiation [OR=0.80, 95%C1 (0.49, 1.32), P=0.39], but correlated with the tumor location [OR=1.85, 95%C1 (1.01, 3.37), P=0.04], RAS wild-type gene [OR=6.36, 95%C1 (3.41, 11.87), P<0.000 01], TNM stage [OR=0.45, 95%C1 (0.32, 0.64), P<0.000 01], lymph node metastasis [OR=1.54, 95%C1 (1.12, 2.13), P=0.008], and the depth of tumor invasion [OR=0.17, 95%C1 (0.05, 0.55), P=0.003].ConclusionCurrent evidence shows that HER2 amplification is not associated with OS in patients with colorectal cancer, but associated with tumor infiltration, lymph node metastasis, TNM stage, tumor site, and RAS genotype.
