We reviewed all studies assessing the health-related quality of life (HRQoL) in patients with hepatocellular carcinoma (HCC) between 2009 and 2018 (n = 45). Most studies assessed HRQoL as an outcome, and evaluated or compared the HRQoL of HCC patients depending on the type of treatment or stage of disease. HCC patients had a worse HRQoL than the general population, including in those with early-stage HCC. Patients commonly experienced pain, fatigue, sleep disturbance, distress, and lack of appetite, and these symptoms remained problematic even a few years after treatment. TNM classification of malignant tumors stage, tumor stage, presence of cirrhosis, being Asian, being female, living alone, or being unemployed were associated with a poor HRQoL. While recent studies have included a more diverse patient population, various topics, and different study designs, there were limited studies on supportive interventions. Given the increase in HCC cases and HCC survivors, addressing the HRQoL of HCC patients requires more attention.

This study was conducted to investigate the expression of three genes related to early embryonic development in bovine transgenic cloned embryos. To accomplish this, development of bovine transgenic somatic cell nuclear transfer (SCNT) embryos was compared with non-transgenic embryos. Next, mRNA transcription of three specific genes (DNMT1, Hsp 70.1, and Mash2) related to early embryo development in transgenic SCNT embryos was compared between transgenic and non-transgenic SCNTs, parthenogenetic embryos, and in vitro fertilization (IVF) embryos. Transgenic SCNT embryos showed significantly lower rates of development to the blastocyst stage than non-transgenic ones. To investigate normal gene expression, RNA was extracted from ten blastocysts derived from parthenogenesis, IVF, non-transgenic, and transgenic SCNT embryos and reverse-transcribed to synthesize cDNA. The cDNA was then subjected to PCR amplification and semi-quantified. More DNMT1 mRNA was detected in the transgenic SCNT group than the other three groups. Hsp 70.1 mRNA was detected in the IVF embryos, while lower levels were found in SCNT and parthenogenetic embryos. Mash2 mRNA was present at the highest levels in transgenic SCNT embryos. In conclusion, the higher levels of methylation and lower protein synthesis after heat shock in the transgenic SCNT embryos expected based on our results may cause lower embryonic development.

Purpose:
The purpose of the study was to validate the Korean version of Patient-Reported Outcomes Measurement Information System 29 Profile v2.1 (K-PROMIS-29 V2.1) among cancer survivors.
Materials and Methods:
Participants were recruited from outpatient clinics of the Comprehensive Cancer Center at the Samsung Medical Center in Seoul, South Korea, from September to October 2018. Participants completed a survey questionnaire that included the K-PROMIS-29 V2.1 and the European Organisation for Research and Treatment of Cancer Quality of Life Core Questionnaire (EORTC QLQ-C30). Principal component analysis and confirmatory factor analysis (CFA) and Pearson’s correlations were used to evaluate the reliability and validity of the K-PROMIS-29 V2.1.
Results:
The mean age of the study participants was 54.4 years, the mean time since diagnosis was 1.2 (±2.4) years, and 349 (87.3%) completed the entire questionnaire. The Cronbach’s alpha coefficients of the seven domains in the K-PROMIS-29 V2.1 ranged from 0.81 to 0.96, indicating satisfactory internal consistency. In the CFA, the goodness-of-fit indices for the K-PROMIS-29 V2.1 were high (comparative fit index, 0.91 and standardized root-mean-squared residual, 0.06). High to moderate correlations were found between comparable subscales of the K-PROMIS-29 V2.1 and subscales of the EORTC QLQ-C30 (r=0.52-0.73).
Conclusion
The K-PROMIS-29 V2.1 is a reliable and valid measure for assessing the health-related quality of life domains in a cancer population, thus supporting their use in studies and oncology trials.

Purpose:
Fear of cancer recurrence (FCR) is a common psychological issue in breast cancer (BC) survivors during early survivorship but whether the same is true among long-term survivors has yet to be empirically evaluated. This study investigated FCR level, its associated factors, and impact on quality of life (QoL) in long-term BC survivors.
Materials and Methods:
Participants included women diagnosed with BC between 2004 and 2010 at two tertiary hospitals. Survey was conducted in 2020. The study measured FCR with the Fear of Cancer Recurrence Inventory and other patient-reported outcomes, including depression and cancer-related QoL. Logistic regression was used to identify factors associated with FCR, and structural equation modeling was conducted to explore the impact of FCR on other outcomes.
Results:
Of 333 participants, the mean age at diagnosis was 45.5, and 46% experienced FCR. Age at diagnosis ≤ 45 (adjusted odds ratio [aOR], 2.64; 95% confidence interval [CI], 1.51 to 4.60), shorter time since diagnosis (aOR, 1.75, 95% CI, 1.08 to 2.89), and having a history of recurrence (aOR, 2.56; 95% CI, 1.16 to 5.65) was associated with more FCR. FCR was significantly associated with an increased risk of depression (β=0.471, p < 0.001) and negatively impacted emotional functioning (β=–0.531, p < 0.001). In addition, a higher FCR level may impair overall health-related QoL in long-term BC survivors (β=–0.108, p=0.021).
Conclusion
Ten years after diagnosis, long-term BC survivors still experienced a high level of FCR. Further, the negative impact of FCR on QoL and increased depression risk require an FCR screening and appropriate interventions to enhance long-term BC survivors' QoL.

Purpose:
The purpose of the study was to validate the Korean version of Cancer Survivors’ Unmet Needs (CaSUN) scale among non–small cell lung cancer survivors.
Materials and Methods:
Participants were recruited from outpatient clinics at the Samsung Medical Center in Seoul, South Korea, from January to October 2020. Participants completed a survey questionnaire that included the CaSUN. Exploratory and confirmatory factor analysis and Pearson’s correlations were used to evaluate the reliability and validity of the Korean version of the CaSUN (CaSUN-K). We also tested known-group validity using an independent t test or ANOVA.
Results:
In total, 949 provided informed consent and all of which completed the questionnaire. Among the 949 patients, 529 (55.7%) were male; the mean age and median time since the end of active treatment (standard deviation) was 63.4±8.8 years and the median was 18 months. Although the factor loadings were different from those for the original scale, the Cronbach’s alpha coefficients of the six domains in the CaSUN-K ranged from 0.68 to 0.95, indicating satisfactory internal consistency. In the CFA, the goodness-of-fit indices for the CaSUN-K were high. Moderate correlations demonstrated the convergent validity of CaSUN-K with the relevant questionnaire. More than 60% of the participants reported information-related unmet needs, and the CaSUN-K discriminated between the needs reported by the different subgroups that we analyzed.
Conclusion
The CaSUN-K is a reliable and valid measure for assessing the unmet needs in a cancer population, thus this tool help population to receive timely, targeted, and relevant care.
