How Do Patients Value the Benefit of Minimally Invasive Surgery in Cancer Treatment?

OBJECTIVES: Due to the increasing cost of cancer treatment, the demand for value-based healthcare is increasing. Although several value frameworks have been developed recently in the field of oncology, the nononcological benefits of minimally invasive surgery have not been addressed. This study aimed to estimate how patients value nononcological benefits in minimally invasive cancer surgery. METHODS: The value that patients placed on various benefits of cancer surgery was termed throughout the study as patient value (PV). To quantize PVs for the benefits of cancer surgery, a one-tiered analytic hierarchy process model was constructed. The model includes 6 well-known surgical outcomes, including nononcological benefits. The study participants included 303 patients with cancer and family caregivers who participated in a questionnaire survey. RESULTS: The PVs for "decreased operation time," "reduced length of hospital stay," and "improved cosmetic results" were 0.050, 0.044, and 0.045, respectively, whereas the PVs for "increased survival," "prevention of disease recurrence," and "avoidance of complications" were 0.366, 0.292, and 0.203, respectively. The PV placed on nononcological benefits from minimally invasive surgery was one-tenth (10.2%) of the total value. CONCLUSIONS: Nononcological benefits arising from minimally invasive surgery were relatively small but nonnegligible. This value should be considered in the process of developing a value framework for cancer surgery and shared decision making.

Is Korean society prepared for the financial burden of novel anticancer drugs? A survey of willingness to pay among National Health Insurance beneficiaries.

PURPOSE: Since South Korea's 5-year policy of increasing National Health Insurance (NHI) coverage began in 2017, related pharmaceutical expenditures have increased by 41%. Thus, there is a critical need to examine society's willingness to pay (WTP) for increased premiums to include new anticancer drugs in NHI coverage. METHODS: Participants aged 20-65 were invited to a web-based online survey. The acceptable effectiveness threshold for a new anticancer drug to be included in NHI coverage and the WTP for an anticancer drug with modest effectiveness were determined by open-ended questions. RESULTS: A total of 1817 respondents completed the survey. Participants with a family history of cancer or a higher perceived risk of getting cancer had significantly higher WTPs (RR [relative risk] = 1.17 and 1.21, both P = 0.012). Participants who agreed on adding coverage for new anticancer drugs with a life gain of 3 months had a higher WTP (RR = 1.70, P < 0.0001). These associations were greater among the employed and low-income groups. The adjusted mean of acceptable effectiveness for a new anticancer drug was 21.5 months (interquartile range [IQR] = 19.3 to 24.0, median = 21.9). The WTP for a new anticancer drug with a life gain of 3 months was $5.2 (IQR = 4.0 to 6.0, median = 4.6). CONCLUSION: The unrealistic expectations in Korean society for new anticancer agents may provoke challenging issues of fairness and equity. Although Korean society is willing to accept premium increases, our data suggest that such increases would benefit only a small proportion of advanced cancer patients.

The impact of depressive symptoms on health value in patients with gynecologic cancer: A comparison with physical symptoms and performance status.

OBJECTIVE: The importance of managing depressive symptoms is frequently underestimated in the clinic. In this study, the effects of depressive symptoms on health utility value (HUV) in gynecologic cancer patients are evaluated. In addition, the effects were compared with those of performance status and physical symptoms. METHODS: Patient-reported outcome data from 274 gynecologic cancer patients were prospectively collected. HUV was measured using the 3-level version of the EuroQoL 5-dimension descriptive system (EQ-5D-3L) and the EuroQoL visual analog scale (EQ-VAS). The Patient Health Questionnaire-9 (PHQ-9) was used to measure the severity of depressive symptoms. The impact of depressive symptoms on HUV was analyzed using the generalized linear model. RESULTS: Moderate-severe depressive symptoms were significantly associated with a decrease in HUV in gynecologic cancer patients (p < 0.0001 for the EQ-5D-3L and EQ-VAS). Severe fatigue and severe pain were also associated with a decrease in HUV (p = 0.018 and p < 0.0001 for the EQ-5D-3L and EQ-VAS; p < 0.0001 for the EQ-5D-3L, respectively), and the effect sizes were comparable to that of moderate-severe depressive symptoms. In addition to the patients with moderate-severe depressive symptoms, the patients with mild depressive symptoms also experienced a significant decrease in HUV (p < 0.0001 for the EQ-5D-3L and EQ-VAS). The effect size for mild depressive symptoms was comparable to those for mild fatigue or mild pain. CONCLUSIONS: Even mild depressive symptoms may significantly compromise HUV in gynecologic cancer patients, and the effect is comparable to that of performance status or physical symptoms. Gynecologic oncologists should put more effort into properly preventing, detecting, and managing depressive symptoms.

Association of Blood Mercury Level with the Risk of Depression According to Fish Intake Level in the General Korean Population: Findings from the Korean National Health and Nutrition Examination Survey (KNHANES) 2008-2013.

Mercury is a cumulative neurotoxic agent, exposure to high levels of which may increase the risk of psychiatric symptoms. The purpose of this study was to examine the associations between blood mercury and depression risk in Korean adults. We analyzed the Korean National Health and Nutrition Examination Survey (KNHANES) with 11,754 participants (male: 5834 female: 5920) aged ≥19 years from 2008 to 2013. The associations of blood mercury with risk of depression were estimated using multivariate logistic regression after adjustment for potential confounders. We found a significantly increased risk of depression in the highest quintile for blood mercury (multivariate OR = 2.05; 95% CI = 1.20-3.48; P trend = 0.03) among female, but not male. A stratification analysis by fish intake showed that the association between depression and blood mercury was strengthened (OR = 4.00; 95% CI = 1.51-10.6; P trend = 0.015) among females with the lowest tertile of fish intake. The results of this study suggest that higher levels of blood mercury, especially in cases of lower fish intake, are positively associated with the risk of depression in Korean women.

Incidence and costs of cervical intraepithelial neoplasia in the Korean population.

OBJECTIVE: The purpose of this study was to assess the incidence rate of cervical intraepithelial neoplasia (CIN) and cervical cancer, and their costs according to age. METHODS: We collected data on annual incidence and medical costs of CIN and cervical cancer from 2010 until the end of 2014 from the Health Insurance Review and Assessment (HIRA) service. The CIN was classified into CIN3 (high-grade) requiring conization and CIN1/2 (low-grade) requiring observation. RESULTS: Incidence rates of CIN3 and cervical cancer are reducing over time, whereas CIN1/2 is increasing significantly (p for trend: <0.001). The peak ages of incidence were 25-29, 30-34, and 70-74 years old for CIN1/2, CIN3, and cervical cancer, respectively. The crude incidence of CIN1/2 increased by approximately 30% in 2014 compared to 5 years ago and demonstrated an increasing trend in all age groups. The CIN3 showed a significantly increasing trend in the age group of 30-39 years old, the cervical cancer was significantly reduced in all ages, except the 35-39 years old. The treatment for cervical cancer costs $3,342 per year, whereas the treatment for CIN3 and CIN1/2 cost $467 and $83, respectively. CONCLUSION: The crude incidence rate of cervical cancer is currently decreasing among Korean women, but the incidence rates and medical costs of CIN and cervical cancer are increasing in women in their 30s in Korea. These findings suggest that different strategies by age will be required for prevention of cervical cancer in Korea.

High Prevalence of Leptotrichia amnionii, Atopobium vaginae, Sneathia sanguinegens, and Factor 1 Microbes and Association of Spontaneous Abortion among Korean Women.

Objective. The purpose of this study was to (i) determine the cervical microbial composition in different abortion samples and to (ii) investigate the correlation between spontaneous abortion and cervical microbes in Korean women. Methods. We collected cervical swabs from women who had never undergone abortion (N = 36), had spontaneous abortion (N = 23), and had undergone induced abortion (N = 88) and subjected those samples to 16S rRNA pyrosequencing. Further, factor analysis and correlation between cervical microbiota and spontaneous abortion were evaluated by logistic regression analysis. Results. In spontaneous abortion women, 16 S rRNA gene sequences showed significant increases in Atopobium vaginae, Megasphaera spp., Gardnerella vaginalis, Leptotrichia amnionii, and Sneathia sanguinegens compared to women in nonabortion group. In multivariate logistic regression analysis, A. vaginae (OD = 11.27; 95% = 1.57-81), L. amnionii (OD = 11.47; 95% = 1.22-107.94), S. sanguinegens (OD = 6.89; 95% = 1.07-44.33), and factor 1 microbes (OD = 16.4; 95% = 1.88-42.5) were strongly associated with spontaneous abortion. Conclusions. This study showed a high prevalence of L. amnionii, A. vaginae, S. sanguinegens, and factor 1 microbes in spontaneous abortion and association with spontaneous abortion in Korean women.
