Racial and Ethnic Variations in Pre-Diagnosis Comorbidity Burden and Health-Related Quality of Life Among Older Women with Breast Cancer

BACKGROUND

This study examined racial/ethnic differences in comorbidity burden and health-related quality of life (HRQOL) among older women before breast cancer diagnosis.

METHODS

From Surveillance, Epidemiology, and End Results-Medicare Health Outcomes Survey (SEER-MHOS) linked data resource, 2513 women diagnosed with breast cancer at ≥ 65 years between 1998 and 2012 were identified and grouped based on comorbidity burden using latent class analysis. Pre-diagnosis HRQOL was measured using SF-36/VR-12 and summarized to physical (PCS) and mental component summary (MCS) scores. The adjusted least-square means and 95% confidence intervals were obtained according to comorbidity burden and race/ethnicity. The interactions were examined with 2-way ANOVA.

RESULTS

The latent class analysis revealed four comorbid burden classes, with Class 1 being the most healthy and Class 4 being the least healthy. African American (AA) and Hispanic women were more likely to be in Class 4 than non-Hispanic white (NHW) women (18.6%, 14.8%, and 8.3%, respectively). The mean PCS was 39.3 and differed by comorbidity burden and race/ethnicity (Pinteraction < 0.001). There were no racial/ethnic differences in Classes 1 and 2, while NHW women reported significantly lower PCS scores than AA women in Classes 3 and 4. The mean MCS was 51.4 and differed by comorbidity burden and race/ethnicity (Pinteraction < 0.001). There was no racial/ethnic difference in Class 3; however, AA women reported lower MCS scores than Asian/Pacific Islander women in Class 1, and AA and Hispanic women reported lower MCS scores than NHW women in Classes 2 and 4.

CONCLUSION

Comorbidity burden negatively affected HRQOL but differentially for racial/ethnic groups. As the comorbidity burden increases, NHW women are more concerned with physical HRQOL, while AA and Hispanic women are more concerned with mental HRQOL.

Perceived Risk of Solitary Death and Depressive Symptoms Among Older Adults Living Alone in Seoul: Can Structural and Functional Social Support Buffer the Impact?

Although older adults living alone are at a greater risk of solitary death, there is a dearth of literature in this area. Using the 2018 Seoul Elderly Survey, we investigated the extent to which older adults living alone in Seoul perceive the risk of solitary death and examined the association between the perceived risk of solitary death and depressive symptoms. Additionally, we explored the role of structural and functional support in that association as a buffering factor. Results showed that more than half of the older adults living alone in Seoul perceived that they could be victims of solitary death. The perceived risk of solitary death among older adults living alone was independently associated with depressive symptoms. Additionally, the structural aspect of social support moderated the impact of the perceived risk of solitary death on depressive symptoms. Interventions that enhance the structural aspect of social support should be primarily considered.

Exploring Service Use Disparities among Suicidal Black Youth in a Suicide Prevention Care Coordination Intervention

OBJECTIVE

The aim of this study is to examine service utilization disparities among Black youth participating in Linking Individuals Needing Care (LINC), a 90-day research-informed suicide care coordination intervention.

METHODS

An open trial pilot was conducted to examine the effectiveness of LINC in increasing access to and engagement in mental health and non-mental health services among suicidal youth (N = 587). Other variables of interest included service use facilitators and service use barriers. Generalized linear mixed models with binomial distribution and logit link were performed to ascertain if service use facilitators and barriers were associated with service utilization and if disparities in service use and engagement existed between Black and White suicidal youth through a comparative analysis.

RESULTS

Service utilization differences were found between Black and White youth. While Black and White youth were both likely to engage in individual therapy (OR = 1.398, p < .001) and non-mental health services (OR = 1.289, p < .001), utilization rates for mental health and medication management services were lower for Black (55.1% to 60.6%) youth compared to White (66.0% to 71.0%) youth. Specifically, Black youth were significantly less likely than Whites to receive medication management (OR = .466, p = .002). Systemic barriers such long waitlists for care (OR = 1.860, p = .039) and poor relationship with providers (OR = 7.680, p = .028) increased odds of engagement in non-mental health services. Clinical disorders and engagement in suicide-related behaviors increased the likelihood of obtaining care from both medication management and non-mental health services.

CONCLUSION

Care coordination services for suicidal youth can increase access and engagement in mental health and non-mental health services. Culturally adapted models attending to cultural and social assets of Black families are needed to reduce disparities and suicide risk among Black youth.

Caring Transitions - A Care Coordination Intervention to Reduce Suicide Risk Among Youth Discharged From Inpatient Psychiatric Hospitalization

Background: Suicide risk following youth psychiatric hospitalization is of significant concern. This study evaluated Linking Individuals Needing Care (LINC), a theory-driven, comprehensive care coordination approach for youth discharged from crisis services. Aims: To pilot LINC's potential effectiveness in increasing service utilization and decreasing suicide risk. Method: Participants were 460 youth patients who received LINC for approximately 90 days following discharge from crisis services. Service utilization, depressive symptoms, and suicide-related variables were measured at baseline and 30, 60, and 90 days after baseline. Results: Patients significantly increased the use of various beneficial, least restrictive services (individual therapy, medication management, and non-mental health supports) over the 90-day intervention. Significant decreases were observed in depressive symptoms, suicide ideation, and engagement in suicide-related behaviors. Limitations: Absence of a comparison group and nonparticipating families limit causal conclusions and generalizability. Conclusions: LINC may be a promising new approach following inpatient hospitalization that can engage and retain youth in services, likely resulting in improved treatment outcomes. This approach was designed emphasizing patient engagement, suicide risk assessment and management, safety planning, community networking, referral/linkage monitoring, coping and motivational strategies, and linguistic/culturally responsive practices to meet service and support needs of high-risk suicidal youth.

Community welfare resources and late-life depression among older adults in Seoul: A multi-level analysis

OBJECTIVES

This study aimed to examine whether community welfare resources in neighborhoods (recreational facilities, healthcare access, and public welfare expenditure) are associated with late-life depression among older adults in Seoul, South Korea.

METHODS

Data for this study were obtained by merging two different data sources: the 2018 Seoul Elderly Survey for individual-level variables and publicly available administrative data for neighborhood-level variables. The sample included 3036 older adults (unweighted n = 3034) living in 25 neighborhoods (Gu) in Seoul. Multilevel regression models examined the effects of neighborhood-level variables on late-life depression while controlling for individual-level variables. We also explored the extent to which individual characteristics moderate the main effects of neighborhood characteristics on late-life depression.

RESULTS

The results indicated that recreational facilities, health care centers, and public welfare expenditure in the neighborhoods were associated with late-life depression among older adults beyond individuals' predisposing conditions. Also, the effects of recreational facilities and public welfare expenditure on depressive symptoms were larger for those with higher education level.

CONCLUSIONS

Older adults living in neighborhoods with more recreational facilities, more health care centers, and high public welfare expenditure were less likely to experience late-life depression. Of note is that the effects of neighborhoods' recreational facilities and public welfare expenditure varied by certain individual characteristics. Hence, local governments should introduce neighborhood-based health promotion policies to prevent depression among older adults. In doing so, local governments should also consider ways to improve access to community welfare resources for underprivileged older adults.

10-Year Trends of Emergency Department Visits, Wait Time, and Length of Stay among Adults with Mental Health and Substance use Disorders in the United States

This study examined if there was a change in the number of Emergency Department (ED) visits, wait time, and length of stay among adults with mental health and substance use disorders (MHSUD) in the United States from 2006 to 2015. From the National Hospital Ambulatory Medical Care Survey, a total of 17,488 ED visits by adults with MHSUD were identified. Linear regression and negative binomial regression analyses were conducted to assess statistically significant changes in trends of ED visits, wait time, and length of stay. Results indicated that ED visits by adults with MHSUD increased by 30.6% from 2006 to 2015. Wait time of ED visits by adults with MHSUD decreased for the same time period; however, length of stay did not change. Also, there were some differences in trends of wait time and length of stay by diagnosis. Specifically, wait time of ED visits by adults with psychotic disorders did not decrease. Length of stay of ED visits by adults with anxiety disorders statistically significantly increased from 2006 to 2015. More effort is needed to improve the quality of ED care for adults with MHSUD. In such an effort, diagnoses should be taken into consideration.

Characteristics of Emergency Department Visits by Homeless Young Adults in the U.S

PURPOSE

Homeless young adults often seek health care at emergency departments (EDs) after they are no longer able to ignore a pressing health problem. However, a dearth of literature examines homeless young adults' ED visits. This study aimed to increase understanding of ED visits among homeless young adults within the U.S.

METHODS

Data for this study were obtained from the 2011-2015 National Hospital Ambulatory Medical Care Survey. The sample for this study included all ED visits made by homeless and housed young adults aged 18-29 years (unweighted N = 25,068).

RESULTS

ED visits by homeless young adults were distinguished in terms of gender, region, payment sources, and triage level. Furthermore, ED visits made by homeless young adults were more likely related to mental health and suicide. Homeless young adults' ED visits were characterized by a longer average length of stay and were less likely to be referred to a physician or clinic for follow-up, given medication, or have a procedure performed in the ED.

CONCLUSIONS

This study highlighted differences in ED utilization for homeless young adults. The findings of this study suggest a need to further examine the characteristics of ED services received by homeless young adults to better understand differences in ED service receipt related to housing status. This knowledge can inform efforts to reduce costs through improving access to housing and outpatient mental health care and reducing stigma among health care professionals to ensure continuity of care.

Effects of Radiation Therapy and Comorbidity on Health-Related Quality of Life and Mortality Among Older Women With Low-Risk Breast Cancer: Protocol for a Retrospective Cohort Study

Background

The National Comprehensive Cancer Network Breast Cancer Guidelines Committee suggests that the omission of adjuvant radiation therapy (RT) after breast-conserving surgery can be a reasonable option among older women with low-risk breast cancer (early-stage, estrogen receptor-positive, and node-negative) if they are treated with endocrine therapy. However, RT usage in this group of women still exceeds 50%. Conversely, older women tend to forego RT (even when necessary) due to cost, inconvenience, and potential adverse responses associated with RT. Understanding health-related quality of life (HRQOL) change with receipt of RT among older women in the modern era is limited due to the under-representation of this population in clinical trials.

Objective

The proposed study aims to examine the associations of RT with HRQOL trajectories as well as survival outcomes among older women with 5-10 years of follow-up. We will also assess whether prediagnosis comorbidity burden influences receipt of RT and whether the associations between RT and HRQOL trajectory and survival outcomes are modified by the comorbidity burden.

Methods

We will use a retrospective cohort study design with the population-based Surveillance, Epidemiology, and End-Results database linked to the Medicare Health Outcomes Survey (SEER-MHOS). Older women (≥65 years) who were diagnosed with low-risk breast cancer in 1998-2014, received breast-conserving surgery, and participated in MHOS 1998-2016 are eligible for this analysis. The latent class analysis clustering method will be used to identify each patient’s prediagnosis comorbidity burden, and HRQOL will be evaluated using the Short Form 36/Veterans RAND 12-Item Health Survey scales. The inverse-weighted estimates of the probability of treatment will be included to control for treatment selection bias and confounding effects in subsequent analysis. The association of RT with HRQOL trajectory will be evaluated using inverse-weighted multilevel growth mixture models. The inverse-weighted Cox regression model will be used to obtain hazard ratios with 95% CIs for the association of RT with survival outcomes. Differential effects of RT on both outcomes according to comorbidity burden class will also be evaluated.

Results

As of October 2020, the study was approved by the institutional review board, and SEER-MHOS data were obtained from the National Cancer Institute. Women with low-risk breast cancer who met inclusion and exclusion criteria have been identified, and prediagnosis comorbidity burden class has been characterized using latent class analysis. Further data analysis will begin in November 2020, and the first manuscript will be submitted in a peer-reviewed journal in February 2021.

Conclusions

This research can potentially improve clinical outcomes of older women with low-risk breast cancer by providing them additional information on the HRQOL trajectories when they make RT treatment decisions. It will facilitate informed, shared treatment decision making and cancer care planning to ultimately improve the HRQOL of older women with breast cancer.

Abstract 4631: Pre-diagnosis comorbidity class, health-related quality of life, and treatment selection among older women with breast cancer

Purpose of the study: The NCCN guidelines state that adjuvant radiotherapy (RT) can be omitted in older women with estrogen receptor (ER)-positive, node-negative early-stage (i.e., Tis and T1) breast cancer (ESBC). However, there is no specific algorithm to select a subgroup of women who can safely forgo RT. Older women commonly present with multiple comorbid conditions with different levels of functional limitations and health-related quality of life (HRQOL), which challenge the RT-decision process. This study aimed to understand pre-diagnosis comorbidity burdens in this patient group and to examine its relationship with HRQOL and treatment selection in a retrospective cohort study design.

Methods: From the SEER-MHOS database, we included 985 older women who were diagnosed at age ≥ 70 years, with ER-positive, node-negative ESBC between 1998 and 2013. SEER provides primary treatments (surgery and radiation), and MHOS provides self-reported comorbidity, functionality, and HRQOL. We used latent class analysis (LCA) to identify clinically distinct comorbidity burden classes. The associations between the comorbidity burdens with HRQOL and treatment selection (lumpectomy only, lumpectomy + RT, mastectomy, mastectomy + RT) were examined using generalized linear models.

Results: A mean age at diagnosis was 77 years, 81 % of patients were whites, and 43 % were married. A majority had stage I disease (80 %) with 20 % stage 0. About one fourth (26 %) had ≤ 1 comorbid condition, whereas 28 % had ≥ 4 comorbidities. LCA identified four distinct comorbidity burden classes; healthy (n=577, 58 %), low comorbidity with limited functionality (n=64, 7 %), moderate comorbidity with symptoms (n=247, n=25 %), and high comorbidity with highly limited functionality and symptoms (n=97, 10 %). Classes were distinguished by the presence or absence of comorbid conditions and functional limitations as well as symptoms. Comorbidity burdens were independently associated with HRQOL mental component summary (MCS-12) score (p &lt; .0001) and physical component summary (PCS-12) score (p &lt; .0001) but not with treatment selection (p = 0.096). In stage 0, age (p=0.025) and education level (p=0.024) were the independent predictors of treatment selection while age (p&lt;.0001), education level (p=0.0013), income (p=0.044), and obesity (p=0.026) determined the treatment selection in stage I.

Conclusions: Older women with ESBC can be described by four distinct comorbidity burdens that are independent predictors of HRQOL. However, it seems that the comorbidity burdens were not considered in the treatment selection process. Future studies need to address treatment outcomes (such as changes in HRQOL and survival) by comorbidity burdens to better guide treatment decisions.

The predictors of perceived social support among former foster youth

Based on a 5-wave panel survey of 732 foster youth, the current study examined the respective relationships between foster youths' individual characteristics, youths' social connections with individuals and formal institutions, and the development of perceived social support across the transition to adulthood. Several youth characteristics - including self-reported delinquency and attachment insecurity - were found to be statistically significantly associated with perceived social support. Attachment insecurity also appeared to mediate the relationships between social support and several other youth-level characteristics, including prior placement disruptions and placement with relatives. Social connections with different types of individuals - including caregivers, relatives, natural mentors, and romantic partners - were found to be associated with additive increases in perceived social support. However, some types of connections (e.g., romantic partners, natural mentors) appeared to be associated with much larger increases in social support than other connections (e.g., school or employment). Collectively, the findings help inform agencies' efforts to bolster foster youths' social connections as they transition to adulthood.

Tobacco, Alcohol, and Drug Use of People With Mood and Anxiety Disorders: Differential Impact of Family and Friends

OBJECTIVE

Substance use among people with mood and anxiety disorders is highly prevalent. The literature suggests that substance use among people with mood and anxiety disorders is linked to social relational factors, yet it has rarely been the case that studies explicitly examine the differential impact of family and friends. This study investigated the association among family relationships, friendships, and substance use among people with mood and anxiety disorders.

METHODS

Using the National Survey of American Life, structural equation modeling tested the unique effects of family relationships and friendships on tobacco, alcohol, and drug use (n = 1,076). The quality of family relationships was assessed using 12 items on the frequency of contact with family, received help from family, closeness in feeling toward family, and emotional support from family. The quality of friendships was assessed using four items on the frequency of contact with friends, received and given help, and closeness in feeling toward friends. Substance use was measured using self-reported use of tobacco, alcohol, and drugs.

RESULTS

Findings indicated that family relationships (β = -.101, p = .031) and friendships (β = .142, p = .004) were associated with drug use among people with mood and anxiety disorders, controlling for gender, age, race, education level, employment status, income, and family substance use history. Yet, family relationships and friendships were not significantly associated with tobacco and alcohol use.

CONCLUSIONS

People with mood and anxiety disorders who had better family relationships were less likely to use drugs, while those who had better friendships were more likely to use drugs. Practitioners should be attentive to the differential impact of family and friends when working with people with mood and anxiety disorders to reduce the risk of drug use. Family interventions promoting and maintaining quality relationships with family will be helpful. However, friendships may facilitate drug use of people with mood and anxiety disorders. Practitioners should be cognizant of the potential risks of friendship networks for people with mood and anxiety disorders.

Racial/Ethnic Differences in Contemporaneous Use of Mental Health and Substance Use Treatment Among Individuals Experiencing Both Mental Illness and Substance Use Disorders

This study examined whether the well-established racial/ethnic differences in mental health service utilization among individuals with mental illness are reflected in the treatment utilization patterns of individuals experiencing both mental illness and substance use disorders, particularly in regards to the use of contemporaneous mental health and substance abuse treatment. Using pooled data from the National Survey on Drug Use and Health (2009-2013), the patterns of mental health and substance use treatment utilization of 8748 White, Black, or Latino individuals experiencing both mental illness and substance use disorders were analyzed. Multinomial logistic regression was conducted to test the relationships among racial/ethnic groups and the receipt of contemporaneous treatment, mental health treatment alone, and substance use treatment alone as compared with no treatment utilization. Results indicated that Black and Latino respondents were less likely to receive contemporaneous treatment than Whites respondents. Also, significantly associated with outcomes were several interactions between race/ethnicity and predisposing, need and enabling factors known to be associated with service utilization. The findings suggest that an underlying mechanism of racial/ethnic differences among individuals with co-occurring mental illness and substance use disorders in the treatment utilization may differ by the specific types of treatment and between Blacks and Latinos. Therefore, efforts to reduce these disparities should consider specialty in each treatment settings and heterogeneity within diverse racial/ethnic groups.

Criminal Justice Contact and Treatment Utilization Among People With Mental Illness and Substance Use Disorders

OBJECTIVE

This study examined whether a history of criminal justice involvement is related to the use of contemporaneous mental health and substance abuse treatment among adults experiencing co-occurring disorders.

METHODS

Pooled 2009-2013 data from the National Survey on Drug Use and Health were used to analyze patterns of mental health and substance abuse treatment utilization of 8,740 adults with past-year co-occurring disorders.

RESULTS

Individuals with a criminal history were more likely than those without a criminal history to receive both types of treatment or substance abuse treatment alone.

CONCLUSIONS

The criminal justice system appears to be facilitating mental health and substance abuse treatment among people experiencing co-occurring disorders but may also be overreliant on substance abuse treatment alone.

Predictive and prognostic functions of microtubule-associated protein-tau and topoisomerase IIα protein in early breast cancer

e22169

Background: Topoisomerase IIα protein(topo II) is the molecular target of topo II inhibitors such as anthracyclines and Microtubule-Associated Protein(MAP)-tau protein is associated with taxane sensitivity. Anthracyclins and taxanes are major cytotoxic agents of breast cancer in the adjuvant setting. The aim of this study was to evaluate the predictive and prognostic functions of MAP-tau and topo II in early breast cancers. Methods: Representative breast tumor sections were constructed from paraffin embedded specimens from 78 node positive breast cancer patients. MAP-tau and topo II protein were assessed by immunochemistry using antibody clone 4F1(Affinity BioReagents,USA) and clone Ki-S1 antibody(Dakocytomation,USA). MAP-tau staining of tumor cells was semiquantatively scored as 0, 1+, 2+, 3+ and cases with 0 or 1+ staining intensity were considered MAP-tau negative. Topo II protein over- expression was defined as the detection of nuclear staining in more than median value of evaluated cells. Results: Thirty- four cases (43.6%) of 78 samples showed topo II overexpression and 35 cases(44.9%) showed MAP-tau overexpression in node positive breast cancers. HER2 overexpression was noted in 28 samples (35.9%) and 56 cases (71.8%) were compatible with the luminal type. In 43 patients (55.1%), anthracyclin and taxane were used as adjuvant therapy and in this group, both MAP-tau and topo II overexpression showed lower disease-free survival (DFS) than the others, but statistically not significant. In luminal type, MAP-tau overexpression was poor prognostic factor on DFS in Cox regression.(HR 5.644, 95% CI 1.14–28.07, p=0.034) Conclusions: Topo II overexpression and MAP-tau overexpression in node positive breast cancers were not significant predictive factors for anthracyclin and taxane therapies. As several investigators reported, MAP-tau is associated endocrine therapy sensitivity in patients without chemotherapy, but higher MAP-tau in luminal type was a strong poor prognostic factor in patients who were given chemotherapy and hormonal therapy.

A case of placenta increta presenting as delayed postabortal intraperitoneal bleeding in the first trimester

Placenta increta is an uncommon and life-threatening complication of pregnancy characterized by complete or partial absence of the decidua basalis. Placenta increta usually presents with vaginal bleeding during difficult placental removal in the third-trimester. Although placenta increta may complicate first and early second-trimester pregnancy loss, the diagnosis can be very difficult during early pregnancy and thus the lesion is difficult to identify. We encountered with a woman who was diagnosed with placenta increta after receiving emergency hysterectomy due to intraperitoneal bleeding 2 months after an uncomplicated dilatation and curettage in the first trimester. Therefore, we report this case with a brief review of the literature.

Endometrial stromal sarcomas: A retrospective analysis of 28 patients, single center experience for 20 years

16053

Background: Little is known about the pathogenesis, risk factors, optimal therapy or outcomes of endometrial stromal sarcoma (ESS). The aim of this study is to evaluate the behavior of ESS in relation to its clinical and pathogenic features and to find the better treatment strategy. Methods: A retrospective analysis was performed of 28 patients with histologically proven ESS treated at our institution between 1987 and 2006. Results: The median follow-up time was 54.7±63.1 months and 5-year survival rate was 82.0%. 16 (57.1%) patients were referred to our institution from private clinics for further treatment of the ESS. They were previously undergone either hysterectomy, myomectomy, or hysteroscopy for presumed benign gynecological conditions. 22 patients (81.5%) showed low grade and 5 patients (18.5%) showed high grade disease. A univariate analysis revealed that histologic grade according to mitotic count is associated with longer survival (p=0.004). However, among those with low grade tumor, 5/20 patients (25%) had recurrence and 2/21 (9.5%) had distant metastasis during the follow-up period. Except for 2 cases, 26 patients with ESS had hysterectomy for their primary treatment. Adjuvant treatment after surgery was performed in 14/26 cases (53.8%). Hormone therapy by progesterone, chemotherapy and/or radiotherapy individually did not influence the overall survival of the patients. However, postoperative adjuvant therapy group regardless of the treatment modality was associated with relatively increased overall survival when compared to the surgery only group (p=0.054). Conclusions: Differential diagnosis of ESS from other benign gynecologic diseases before surgery is a difficult problem. Furthermore, it is advised that postoperative adjuvant therapy should be performed after hysterectomy to prevent recurrence or distant metastasis.

Clinical analysis of multiple primary cancers

19639

Background: Multiple primary cancers are defined as two or more abnormal growths of tissue occurring simultaneously or abnormal growths of tissues that follow a previous neoplasm but are not metastases of the latter in the same individual. The primary objective of this study was to determine the occurrence, clinical characteristics and prognosis of multiple primary cancers in single institution, respectively. Methods: Between January 1995 and June 2006, patients with multiple primary cancers were selected from a review of patients who had been treated and followed-up in our Ewha Womans University Hospital. Demographic data were obtained from medical records. Results: Two hundred seven patients were selected and patients with multiple primary cancers constituted 1.95% of all malignancies. Male to female ratio was 1.84. (male 134 vs. female 73 patients) The median age first cancer diagnosis was 67 years old in male, 57 in female. The incidence of synchronous cancers is higher than metachronous. (108 vs. 99) and the median time to additional cancers in metachronous group was 35 months. The most frequent cancers was gastrointestinal cancers in both sex synchronously and metachronously. In male, colorectal cancer followed by gastric cancer methchronously (9.1%), genitourinary cancer with another genitourinary cancer synchronously (12.7%) were frequently observed. In female, breast cancer followed by colorectal cancer metachronously (6.8%), gastric cancer with colorectal cancer (6.9%) were frequently observed. The median survival duration was 14.4 months totally from the index diagnosis and synchronous cancers showed lower survival duration than metachronous cancers. (7.4 vs. 26.1 months, p=0.017) Conclusions: Adequate investigations including G-I tract should focus in the first 3 years after initial diagnosis to detect second primary cancers earlier.

Methylation of p16INK4a is a non-rare event in cervical intraepithelial neoplasia

The cell cycle inhibitor, p16INK4a may be a useful surrogate biomarker of cervical intraepithelial neoplasia (CIN); however, there is currently no consensus of p16INK4a genetic alterations throughout the multiple step process of CIN. Our goal was to identify the methylation frequency of p16INK4a in each step of CIN that is associated with human papillomavirus (HPV) infection, using several different detection methods of p16INK4a methylation to correlate the data. The present study included a total of 43 patients, including 38 with CIN, and 5 normal patients. Three different methods were used to detect hypermethylation of CpG islands, methylation-specific PCR (MSP) amplification of different primer sets of M1, M2, and M3, pyrosequencing of each forward primer region, and immunohistochemistry of p16INK4a. Analysis of MSP showed that 20 of the 38 CIN patients (52.6%) revealed hypermethylation in at least 1 primer set of the p16INK4a promoter. A complete loss of p16INK4a protein expression was observed in 11 cases (28.9%). There was no observed association of methylation of the p16INK4a gene with either CIN grading (P=0.0698) or HPV status (P=0.2811): specifically 42.9% (3/7) was found in CIN 1, 57.1% (8/14) in CIN 2, and 52.9% (9/17) in CIN 3. In concordance with immunohistochemistry results, hypermethylation of the p16INK4a promoter was significantly correlated with a lack of p16 protein expression (P=0.0145). All positive peaks from pyrosequencing matched the MSP results, which ranged from 6.3% to 24.5%. In conclusion, p16INK4a gene silencing during CIN was not determined to be a particularly rare event; however, it does not correlate with either HPV status or CIN grading.

Reducing whole-body vibration and musculoskeletal injury with a new car seat design

A new car seat design, which allows the back part of the seat (BPS) to lower down while a protruded cushion supports the lumbar spine, was quantitatively tested to determine its effectiveness and potentials in reducing whole-body vibration (WBV) and musculoskeletal disorders in automobile drivers. Nine subjects were tested to drive with the seat in: 1) the conventional seating arrangement (Normal posture); and 2) the new seating design (without BPS (WO-BPS) posture). By reducing contact between the seat and the ischial tuberosities (ITs), the new seating design reduced both contact pressure and amplitude of vibrations transmitted through the body. Root-mean-squared values for acceleration along the z-axis at the lumbar spine and ITs significantly decreased 31.6% (p < 0.01) and 19.8% (p < 0.05), respectively, by using the WO-BPS posture. At the same time, vibration dose values significantly decreased along the z-axis of the lumbar spine and ITs by 43.0% (p < 0.05) and 34.5% (p < 0.01). This reduction in WBV allows more sustained driving than permitted by conventional seating devices, by several hours, before sustaining unacceptable WBV levels. Such seating devices, implemented in large trucks and other high-vibration vehicles, may reduce the risk of WBV-related musculoskeletal disorders among drivers.

Capecitabine Monotherapy in Patients with Anthracycline- and Taxane-Pretreated Metastatic Breast Cancer

The selection of chemotherapeutic regimens is challenging for metastatic breast cancer (MBC) patients whose diseases have failed to respond to anthracyline and taxane. Capecitabine has advantages of oral administration and favorable toxicity profiles. This study was conducted to evaluate the efficacy of capecitabine and to identify the subgroup of patients who would potentially have benefit from capecitabine monotherapy in patients with anthracycline- and taxane-pretreated MBC. Female patients with MBC who had been previously treated with anthracycline and taxane received oral capecitabine 2500 mg/m(2) divided in two doses daily for 2 wk with 1-wk rest period. Between September, 1999, and December, 2002, a total of 38 patients were enrolled. Among the 36 evaluable patients, one patient achieved a complete response (CR), 9 patients had partial responses (PRs), and 13 patients had stable diseases (SDs). Response rate was 26% [95% confidence interval (CI), 12-40%] and the tumor control rate (TCR, CR+PR+SD) was 61% (95% CI, 45-77%). The median follow-up duration was 27.8 mo. The median duration of response was 8.9 mo, the median time to progression was 4.6 mo, and the median overall survival was 18.1 mo. The major toxicities were hand-foot syndrome, diarrhea, and emesis. There was no treatment-related death. The predictors of better overall survival were positivity of hormone receptor, disease-free survival longer than 1 yr, non-refractoriness to anthracycline, and fewer number (<or= 3) of involved organs. Capecitabine monotherapy is effective and well tolerated for MBC patients who had previously been treated with anthracycline and taxane. The TCR could predict overall survival as well as the objective response in this study, suggesting a possible role of TCR as a surrogate marker for survival in MBC patients on salvage chemotherapy. The patients who have relatively slow growing tumor and less tumor burden could have benefit from capecitabine monotherapy following anthracycline- and taxane-based chemotherapy.

Adult T-cell leukemia/lymphoma with features of CD30-positive anaplastic large cell lymphoma--a case report

We experienced a 58-year-old Korean man with adult T-cell leukemia/lymphoma with features of histologically anaplastic large cell lymphoma involving the skin and testis. The patient had cutaneous nodules in both extremities and a palpable right testicular mass. Right orchiectomy was performed and specimens of removed testicle and skin nodules showed immunohistologically anaplastic large cell lymphoma with T-cell phenotype, and CD30 antigen was positive. A human T-cell lymphotropic virus type 1 (HTLV-1) antibody titer was over 1 : 256 and integration of HTLV-1 proviral DNA pX gene was identified in the peripheral blood mononuclear cells and lymphoma tissue by polymerase chain reaction. Peripheral blood and bone marrow did not show any evidence of characteristic neoplastic T-cells.
