Use of complementary and alternative medicine by lymphoma survivors in South Korea.

PURPOSE: We aimed to examine the experience of complementary and alternative medicine (CAM) use and its association with health-related quality of life (HRQOL) in lymphoma survivors in South Korea. METHODS: The participants were 869 lymphoma survivors from three hospitals in South Korea, all diagnosed with lymphoma at least 24 months prior to participation. Self-reported questionnaires were used to assess CAM use. The questionnaire addressed types of CAM used, sources of information about CAM, reason for CAM use, satisfaction with CAM use, discussion of CAM use with doctors, experience of side effects, costs of CAM use, and intentions to continue using CAM. HRQOL was measured with the EORTC QLQ-C30. RESULTS: Of the 869 participants, 42.2% had experience using CAM, and there were statistically significant differences among CAM users and non-users in terms of sex, religion, and time since diagnosis. A special diet (e.g., ginseng, chitosan, mixed cereals) was the most commonly used type of CAM, and most CAM users (82.1%) were satisfied with their CAM use. Most CAM users (77.5%) did not discuss the use of CAM with their doctors, and only 9.2% reported any side effects from CAM. CAM users showed significantly lower HRQOL scores than did non-users. CONCLUSION: A significant number of lymphoma survivors in Korea have used CAM, and most CAM users are satisfied with their CAM use. Oncology nurses should be aware of the range of CAM use among patients and reflect their responses in their treatment and/or follow-up care.

A prospective randomized controlled trial of hydrating nail solution for prevention or treatment of onycholysis in breast cancer patients who received neoadjuvant/adjuvant docetaxel chemotherapy.

PURPOSE: Onycholysis and other nail toxicities occur in approximately 20-30% of breast cancer (BC) patients receiving docetaxel chemotherapy. Onycholysis is often associated with painful paronychia, decreasing patients' quality of life. In this study, we aimed to evaluate the efficacy of hydrating nail solution (HNS) (EVONAIL® solution, Evaux Laboratories, France) for the prevention and treatment of docetaxel-induced onycholysis and nail toxicities. METHODS: This study was a prospective, randomized, controlled study of HNS for the prevention or treatment of onycholysis in patients with docetaxel after doxorubicin plus cyclophosphamide. In the experimental arm, patients painted HNS on nails and periungual areas once a day till developing onycholysis grade 2. After grade 2 onycholysis development, patients applied HNS twice a day regardless of treatment arm. The primary endpoints were the incidence of onycholysis grade 2 and recovery rate from grade 2 onycholysis. RESULTS: From August 2015 to May 2016, 103 patients were enrolled and completed this study. Of these, 25 cases of grade 1 and 22 of grade 2 onycholysis were observed. Prophylactic application of HNS resulted in a statistically significant reduction of grade 2 onycholysis compared to controls (P = 0.001) and all grade onycholysis was also significantly lower in the experimental arm (P = 0.034). Multivariate analysis showed that HNS decreased grade 2 onycholysis (Hazard ratio (HR) 0.366, 95% confidence interval (CI) 0.148, 0.902; P = 0.029) and all grade onycholysis (HR 0.372, 95% CI 0.201-0.687, P = 0.002). CONCLUSIONS: Hydrating nail solution significantly reduced the incidence of docetaxel-induced onycholysis in BC patients (NCT02670603).

Sexual problems in male vs. female non-Hodgkin lymphoma survivors: prevalence, correlates, and associations with health-related quality of life.

The objective of this study was to examine the prevalence and factors associated with sexual problems and their relationship to health-related quality of life (HRQOL) in male and female non-Hodgkin lymphoma (NHL) survivors. In this cross-sectional study, 738 NHL survivors (425 men and 313 women; mean time since diagnosis, 6.2 years) in South Korea completed the six-item instrument of adult sexual behavior used by the National Health and Social Life Survey in the United States. HRQOL was measured by two subscales of the EORTC QLQ-C30. Sexual problems were reported by a greater proportion of women (range, 31.9 to 64.4%) than men (range, 23.3 to 49.1%). Among four items common to both sexes, three (lacking interest in sex, unable to achieve orgasm, sex not pleasurable) were significantly more prevalent in women. Significant factors associated with multiple sexual problems in men were older age and being unemployed; in women, they were marital status and comorbidity. Lastly, more significant associations between sexual problems and HRQOL were observed in men than in women. Male and female NHL survivors differ in the prevalence of sexual problems and the factors associated with them as well as their associations with HRQOL. These findings can be used to develop sex-specific interventions to improve sexual function in this population.

Unmet needs of non-Hodgkin lymphoma survivors in Korea: prevalence, correlates, and associations with health-related quality of life.

OBJECTIVE: We aimed to describe the prevalence and correlates of unmet needs among non-Hodgkin lymphoma (NHL) survivors in Korea and to identify their association with health-related quality of life (HRQOL). METHODS: Participants were 826 NHL survivors from three hospitals in South Korea diagnosed at least 24 months prior to participating (mean, 6.3 years; range, 2.1-20.9 years). We used self-reported questionnaires, including the Need Scale for Cancer Patients Undergoing Follow-up Care (NS-C) developed in Korea and the EORTC QLQ-C30. We defined an unmet need as a moderate to high level of unmet need in the NS-C response scale. RESULTS: Among six domains, unmet need prevalence ranged from 1.7% to 38.3%. Most commonly reported domains with unmet needs were 'treatment and prognosis' (38.3%) and 'keeping mind under control' (30.5%). The three most frequently reported individual unmet needs were 'being informed about prevention of recurrence' (50.7%), 'being informed about prevention of metastasis' (49.7%), and 'having self-confidence of overcoming cancer' (42.7%). Multivariate logistic analyses revealed that younger age, being unmarried, and low monthly income were associated with unmet needs of multiple domains. Participants with unmet needs demonstrated significantly poorer HRQOL, and the most clinically meaningful differences were found in social function and emotional function. CONCLUSIONS: Korean NHL survivors have substantial unmet needs, especially those who are younger, unmarried, and have a lower income. Initiating supportive care programs for meeting unmet needs may enhance their HRQOL. Copyright © 2016 John Wiley & Sons, Ltd.

A risk stratification by hormonal receptors (ER, PgR) and HER-2 status in small (< or = 1 cm) invasive breast cancer: who might be possible candidates for adjuvant treatment?

As the use of screening mammography expands, the proportion of invasive breast cancer > or = 1 cm is increasing. The aims of this study were: (1) to identify risk factors for systemic metastases in patients with > or = 1 cm invasive breast cancer and (2) to investigate the patient groups at the greatest risk for metastases with such small tumors. Data were collected retrospectively from the breast cancer registry of our institution for patients with invasive breast cancer from October 1994 to December 2004. Of 4,036 patients who received curative breast cancer surgery, we identified 427 patients who had T1a or T1b breast cancer excluding 39 patients who received neoadjuvant chemotherapy. Ipsilateral axillary lymph node involvement was found in 13% (57/427) of patients at the time of surgery. A multivariate analysis was conducted in 370 (T1aN0, T1bN0) patients without lymph node involvement. In a Cox-regression model, HER-2 positive and triple negative (TN) groups were identified as independent risk factors to predict distant relapse-free survival (DRFS) [Hazard ratio (HR) 8.8, P = 0.003 for HER-2 positive group; HR 5.1, P = 0.026 for TN group] in T1bN0 tumors. Statistical significance was not maintained when the analysis was limited to T1aN0 tumors. Even though T1aN0 and T1bN0 tumors have a relatively low risk of systemic failure, antiHER-2-directed therapy for HER-2 group and new innovative adjuvant systemic treatment for TNBC patients with T1bN0 tumors should be considered. Prospective adjuvant trials are warranted in these subgroups of patients.
