RESUMEN

Acute myeloid leukemia (AML) in older patients has a poor prognosis, low complete remission (CR) rates, and poor overall survival (OS). Preclinical studies have shown synergistic effects of epigenetic priming with hypomethylating agents followed by cytarabine. Based on these data, we hypothesized that an induction regimen using epigenetic priming with decitabine, followed by cytarabine would be effective and safe in older patients with previously untreated AML. Here, we conducted a phase 2 trial in which older patients with previously untreated AML received an induction regimen consisting of 1 or 2 courses of decitabine 20 mg/m2 intravenously (IV) for 5 days followed by cytarabine 100 mg/m2 continuous IV infusion for 5 days. Forty-four patients (median age 76 years) were enrolled, and CR/CRi was achieved by 26 patients (59% of all patients, 66.7% of evaluable patients). Fourteen of 21 (66.7%) patients with adverse cytogenetics achieved CR including six out of seven evaluable patients with TP53 mutations. The 4- and 8-week mortality rates were 2.3% and 9.1%, respectively, with median OS of 10.7 months. These results suggest epigenetic priming with decitabine followed by cytarabine should be considered as an option for first-line therapy in older patients with AML. This trial was registered at www.clinicaltrials.gov as # NCT01829503.

RESUMEN

PURPOSE: Disparities in cancer care persist between patients living in rural versus urban areas. The COVID-19 pandemic may have impacted concerns related to care and personal health differently in rural cancer patients. Using survey data collected from cancer patients in western Pennsylvania, we examined pandemic-related distress, concerns related to cancer care, impact on personal health, and the extent to which these differed by urban-rural residence. METHODS: Patients filled out an initial survey in August-December 2020; a second survey was completed in March 2021. The following patient concerns related to the pandemic were evaluated: threat of COVID-19 to their health, pandemic-related distress, perceptions of cancer care, and vaccine hesitancy. Multivariable logistic regression models were used to examine relationships between these outcomes and urban-rural residence as well as patient-related factors, including anxiety symptoms and social support. RESULTS: The study sample included 1,980 patients, 17% resided in rural areas. COVID-19 represented a major or catastrophic threat to personal health for 39.7% of rural and 49.0% of urban patients (p = 0.0017). Patients with high general anxiety were 10-times more likely to experience pandemic-related distress (p < 0.001). In the follow-up survey (n = 983), vaccine hesitancy was twice as prevalent among rural patients compared to urban (p = 0.012). CONCLUSIONS: The extent to which perceptions of the threat of COVD-19 to personal health and vaccine hesitancy exacerbates rural-urban disparities in cancer care and prognosis warrants further study. Cancer patients may be vulnerable to heightened anxiety and distress triggered by the pandemic.

RESUMEN

BACKGROUND: Cancer-related cognitive impairment (CRCI) has long-term effects on survivor quality of life, but CRCI research on patients with gastrointestinal stromal tumor (GIST) is lacking. The aims of this study were to investigate CRCI and concomitant quality of life among patients with GIST. METHODS: An online survey was used to assess CRCI in adult patients with GIST using the validated Functional Assessment of Cancer Therapy-Cognitive-v.3. Age, education, demographically indexed IQ, general health, and quality of life factors (e.g., fatigue, emotional distress) were also assessed. The online survey was administered through five international GIST and sarcoma support organizations. RESULTS: Over the 3-month recruitment period, the survey was completed by 485 participants: mean age, 57.80 (SD, 11.51), median 5 years after diagnosis. A majority (63.91%) reported experiencing cognitive symptoms with a significant negative quality of life impact. Controlling for age, patients with GIST ≥5 years after diagnosis reported worse cognitive function than those <5 years after diagnosis (p < .05) but did not differ in educational level or IQ. Whereas longer term survivors were more likely to have been treated with tyrosine kinase inhibitor (TKI) therapies, there was no observed association of TKI therapy with self-reported cognitive impairments. CONCLUSIONS: A majority of GIST patients report cognitive symptoms that have a negative impact on quality of life, with longer term survivors (≥5 years) tending to report more cognitive impairments. Given the success of TKI therapy to substantially increase overall survival of patients with GIST, addressing CRCI in clinical practice may improve long-term GIST survivor function and quality of life.

RESUMEN

PURPOSE: Central venous catheters (CVCs) are widely used in acute myeloid leukemia (AML) patients. Complications associated with CVCs are frequently encountered and contribute to morbidity and mortality. Prospective studies investigating and comparing complications of different types of CVCs in AML patients and their effects on the quality of life are limited. METHODS: We conducted a prospective observational study and evaluated the complications associated with the use of CVCs in adult AML patients during induction chemotherapy and evaluated quality of life outcomes as reported by the patients during and after their hospitalization. RESULTS: Fifty newly diagnosed patients with AML (median age, 59 years) who received intensive induction chemotherapy were enrolled in the study. Twenty-nine patients (58%) had a peripherally inserted central catheters (PICCs) placed and 21 (42%) patients received a Hickmann tunneled central catheter (TCC). Three percent of cases developed catheter-related thrombosis in PICCs and no thrombosis in TCCs. Catheter-related bloodstream infection was diagnosed in 8% of patients. CVC occlusion occurred in 44 patients (88%). The total number of occlusion events was 128; 97% of patients with PICCs and 76% of patients with TCCs (p = 0.003). All patients reported that the use of CVC simplified their course of treatment. Most patients reported similar restrictions in activity associated with TCCs and PICCs. CONCLUSION: The present study demonstrates that thrombosis and catheter-related bloodstream infections remain important complications of CVCs in AML patients. Occlusion rates were higher with the use of PICCs and the use of CVCs impacted the quality of life.

RESUMEN

OBJECTIVES: This study examines the associations of cancer death and aspects of the 24-h circadian rest-activity rhythm (RAR) on depression symptoms in older spouses. METHODS: Participants included 46 adults aged 60-94 years (M = 73 years) who experienced the death of a spouse. We tested a multivariate model using cancer death (vs. non-cancer death) and RAR variables as correlates of depression symptoms while controlling for age, sex, physical illness burden, and preparedness for death. We also present a case example to describe the behavioral activity patterns of a participant bereaved by cancer. RESULTS: Cancer death was associated with elevated levels of depression symptoms. However, the timing of the RAR moderated this association. Cancer bereavement was associated with depression symptoms when participants "settled-down" after 11:00 PM. The case example illustrates how intrusive thoughts about death quality impacts a widower's drive to stay busy with daily activities. CONCLUSIONS: Settling down earlier in the evening is important for older spouses bereaved by cancer, in terms of fewer symptoms of depression. CLINICAL IMPLICATIONS: Objectively specifying the activity patterns of older spouses bereaved by cancer is a promising avenue for interventions that aim to reduce depression symptoms.

RESUMEN

OBJECTIVE: Survivors of multiple primary cancers (MPC) are at increased risk for poor health outcomes compared with survivors of single cancers. Using an adapted psychobehavioral stress-response model, the study purpose was to identify pathways and individual risk factors associated with poor health outcomes in adults with MPC. METHODS: Adult MPC survivors (N = 211) with first cancers (stages I-III) diagnosed within 1 to 10 years were recruited via tumor registry. Employing a cross-sectional design, established questionnaires were used to operationalize patient characteristics and theoretical constructs including perceived stress, psychological and behavioral responses, financial hardship, social role function, and physical health. Disease and treatment data were obtained via registry and medical records. Structural equation modeling (SEM) was performed to fit, test, and modify the hypothesized psychobehavioral model. RESULTS: Following measurement model refinement, an SEM linking self-management behaviors, distress, financial hardship, and functional health demonstrated a good fit: χ2 (200, N = 206) = 332.06, P < .01; Tucker-Lewis index (TLI) = .95, comparative fit index (CFI) = .96, standardized root mean residual (SRMR) = .06, root-mean-square error of approximation (RMSEA) = .06. Less use of self-management behaviors predicted higher distress which, in turn, predicted higher financial hardship; higher distress and financial hardship predicted poorer functional health. Several sociodemographic and personal factors predicted self-management behaviors and distress. CONCLUSIONS: The hypothesized stress-response model was partially supported. Data supported pathways among self-management behaviors, distress, financial hardship, and functional health. Self-management and distress may represent modifiable intervention targets for MPC survivors. High body mass index (BMI), less education, greater neuroticism, and lower social support were associated with less use of self-management behaviors and higher distress and should be further evaluated as potential markers of vulnerability.

RESUMEN

Background: Persistent breast pain (PBP) is prevalent among breast cancer survivors and has powerful negative psychological consequences. The present study provided a first test of the hypothesis that: (a) pain catastrophizing, (b) heightened perceived risk of cancer, and (c) worry that pain indicates cancer may be independent mediating links between breast cancer survivors' experiences of PBP and heightened emotional distress. Methodology: We assessed levels of PBP and psychological factors in breast cancer survivors (Survivor Group: n = 417; Stages I-IIIA; White = 88.7%; Age M = 59.4 years) at their first surveillance mammogram post-surgery (6-15 months). A comparison group of women without histories of breast surgery or cancer (Non-cancer Group: n = 587; White = 78.7%; Age M = 57.4 years) was similarly assessed at the time of a routine screening mammogram. All women completed measures of breast pain, pain catastrophizing, perceived breast cancer risk, and worry that breast pain indicates cancer, as well as measures of emotional distress (symptoms of anxiety, symptoms of depression, and mammography-specific distress). Analyses included race, age, BMI, education, and menopausal status as covariates, with significance set at 0.05. Results: As expected, PBP prevalence was significantly higher in the Survivor Group than in the Non-cancer Group (50.6% vs. 17.5%). PBP+ survivors also had significantly higher levels of emotional distress, pain catastrophizing, mammography-specific distress, and worry that breast pain indicates cancer, compared to PBP- survivors. Structural equation modeling results were significant for all hypothesized mediational pathways. Interestingly, comparisons of PBP+ to PBP- women in the Non-cancer Group showed similar results. Conclusion: These findings suggest the importance of (a) pain catastrophizing, (b) perceived breast cancer risk and, (c) worry that breast pain may indicate cancer, as potential targets for interventions aimed at reducing the negative psychological impact of PBP in post-surgery breast cancer survivors, as well as in unaffected women with PBP due to unknown reasons.

RESUMEN

PURPOSE: Given the complexities and risks of allogeneic HCT, patients and their family caregivers may experience elevated psychological distress, including symptoms of anxiety and depression, in anticipation of the procedure. Patients and caregivers also bring with them their pre-HCT experiences of diagnosis, prior treatment, and associated burdens, thus potentially compounding their acute distress. Identification of clinical, psychosocial, and sociodemographic factors related to pre-HCT distress would allow targeting of patients and caregivers who may require assistance during the HCT process. METHODS: Consecutive patients (n = 111) and their caregivers (n = 110) completed measures of anxiety, depression, cancer distress, perceived threat, perceived control, self-efficacy, relationship quality, and physical quality of life in the week before HCT. Multivariate linear regression analysis was used to identify factors associated with patient and caregiver anxiety or depression, including disease type, donor type, and patient and caregiver sociodemographic, health-related, and psychosocial factors. RESULTS: Family caregivers had higher levels of anxiety and depression symptoms than patients. Thirty percent of caregivers vs. 17% of patients met criteria for clinically significant anxiety and a lesser amount (5% for both) met criteria for clinically significant depression. Patient anxiety was related to younger age (b = - 0.22, p = 0.005) and greater cancer-related distress (b = 0.59, p < 0.001), while caregiver anxiety was related to lower self-efficacy (b = - 0.19, p = 0.011) and greater cancer-related distress (b = 0.58, p < 0.001). Similarly, patient depression was related to lower perceived control (b = - 0.17, p = 0.050), greater cancer-related distress (b = 0.34, p = 0.005), and lower physical functioning (b = - 0.26, p = 0.008), while caregiver depression was related to greater cancer-related distress (b = 0.46, p < 0.001). CONCLUSIONS: Family caregivers may be more emotionally vulnerable than patients before HCT and in need of additional assistance. Cancer-related distress was the strongest correlate of anxiety and depression in both patients and caregivers, suggesting that distress related to their cancer experience and its consequences plays a major role in their emotional functioning prior to HCT.

RESUMEN

BACKGROUND: The aim of this study was to examine predictors of health behaviors over time and the link between health behaviors and survival after a diagnosis of advanced cancer. METHODS: Patients with a diagnosis of advanced cancer were administered a battery of questionnaires measuring optimism, depressive symptoms, physical activity, intake of fruits and vegetables, and alcohol and tobacco use over an 18-month period. Analyses included generalized linear mixed models and Cox regression survival analyses. RESULTS: Of the 334 patients enrolled in the study, the mean age at cancer diagnosis was 62 years; the majority were male (62.3%) and white (91%). Twenty percent of the patients reported using alcohol, 19% reported using tobacco, 19% reported eating fewer fruits and vegetables than recommended by the Centers for Disease Control and Prevention and 28% reported physical inactivity after the diagnosis of advanced cancer. Clinical levels of depressive symptoms were associated with lower intake of fruits and vegetables (t = 2.67, P = .007) and physical inactivity (t = 2.11, P = .035). Dispositional optimism was positively associated with physical activity (t = -2.16, P = .031) and a lower frequency of tobacco use (Z = -2.42, P = .015). Multivariate analyses revealed that after adjusting for demographic variables (age and sex), depressive symptoms, and disease-specific factors (diagnosis, tumor size, cirrhosis, vascular invasion, and number of lesions), alcohol use (χ2 = 4.1186, P = .042) and physical inactivity (χ2 = 5.6050, P = .018) were linked to an poorer survival. CONCLUSIONS: Greater dissemination and implementation of effective interventions to reduce alcohol use and increase physical activity in cancer patients are recommended.

RESUMEN

Background: Postoperative ambulation is encouraged to promote timely recovery but is rarely monitored objectively or examined as a predictor of clinical outcomes, despite growing availability of wearable devices that allow passive quantification and remote real-time monitoring of the number of steps taken during recovery. Purpose: To determine whether the number of steps taken during inpatient recovery predicts 30- and 60-day readmission risk after metastatic cancer surgery. Methods: Patients diagnosed with metastatic peritoneal cancer and scheduled for surgical resection were enrolled in this observational cohort study at their preoperative clinic visit. Fitbits were placed on patients' wrists upon transfer from the ICU following surgery and worn for the duration of their inpatient stay. Information about hospital readmission was extracted from electronic medical records. Results: Seventy-one patients participated in the study (mean age = 57.14, range = 31-80 years; 42% female; 51% diagnosed with appendiceal cancer). Mean steps per day were calculated for each participant over the entire inpatient recovery period (mean stay = 12.12 days, 4-37 days). Readmission within 30 and 60 days was medically indicated for 34% and 39% of patients, respectively. After statistically adjusting for age, body mass index, comorbidity, and length of postoperative stay, higher mean steps per day predicted lower 30-day and 60-day readmission risk. Conclusions: Higher Fitbit step counts during inpatient recovery predicted lower risk of 30- and 60-day readmission after surgery for metastatic peritoneal cancer. Results suggest that passively monitoring perioperative ambulation may identify patients at risk for readmission and highlight opportunities for behavioral intervention.

RESUMEN

OBJECTIVES: The purpose of this study was to evaluate the consistency of the circadian patterns of blood pressure (BP) and heart rate (HR) variation over a three-month time frame in women employed outside the home. METHODS: The subjects were 157 healthy women of varying ethnicity (age = 38.2 ± 8.9) who all worked in similar positions at two major medical centers in New York City. Each wore an ambulatory BP monitor during the course of three mid-week work days approximately one month apart. Hourly BPs and HRs were calculated from 9 am to 6 am the following morning and compared among the three days using anova and t tests. RESULTS: The results indicate that there were virtually no differences in the mean hourly levels of any parameter during the waking period across the three days of assessment. However, mean hourly levels of systolic BP significantly declined from 12 pm to 4 am (P < .04, P = .001, P < .001, P = .001, P = .009, respectively) on the third assessment day compared to the first. CONCLUSIONS: Because BP and HR respond to environmental demands in an allostatic fashion, the consistency in the waking patterns of BP and HR variation suggest that the patterns of demands on a workday are reasonably stable in this sample of women. The decline in systolic pressures from 12 pm to 4 am over the three assessments may indicate an improving ability to sleep with the monitor over time.

RESUMEN

Activation of the sympathetic nervous system (e.g., due to stress) has been implicated in cancer progression and recurrence, but its cancer-promoting effects have been variable between different studies. Here, we report that although catecholamines, mediators of systemic sympathetic activity, display only weak immunosuppressive impact on their own, their combination with inflammatory signals leads to the induction of COX-2 and multiple COX-2-dependent suppressive factors in human myeloid cells and cancer tissues. Human macrophages exposed to epinephrine and TNFα, or macrophages generated in 6day cultures in the presence of epinephrine, expressed high levels of COX-2, IDO and IL-10, and strongly suppressed both the proliferation and IFNγ production of CD8+ T cells. These suppressive effects of epinephrine were counteracted by celecoxib, a selective inhibitor of COX-2 activity, which inhibited the induction of immunosuppressive factors (including the elevated expression of COX-2 itself) and the ability of epinephrine-exposed macrophages to suppress CD8+ T cell responses. The activation of the COX-2/PGE2 system and COX-2-dependent suppressive events were also observed in ex vivo human breast and colon cancer explant cultures and were similarly counteracted by celecoxib. Our preliminary data also indicate elevated COX-2 expression in mammary tumors of chronic stress-exposed mice. The current demonstration of the interplay between inflammation and the induction of immunosuppressive factors by catecholamines suggest a contextual impact of stress, helping to explain variable results of epidemiologic studies of the link between sympathetic activity and cancer progression, and implicating COX-2 blockade as a potential means to mitigate stress-related immune suppression.

RESUMEN

OBJECTIVE: Obesity has been strongly linked to endometrial cancer (EC) risk. A number of potential EC risk biomarkers have been proposed, including heightened pro-inflammatory cytokines and adipokines. To evaluate if bariatric surgery can serve as a means for altering levels of such EC risk biomarkers, we investigated changes in these biomarkers after weight loss. METHODS: Blood samples were collected pre-operatively and 6months post-operatively in 107 female bariatric surgery patients aged 18-72years. Wilcoxon signed-rank tests were used to compare biomarker levels (measured using xMAP immunoassays) pre- and post-surgery. Normative comparisons were implemented to contrast 6-month post-surgery biomarker levels to levels in a sample of 74 age-matched non-obese women. Linear regression was used to evaluate the relationship between biomarker expression at baseline and 6months post-surgery and the relationship between race and biomarker levels. RESULTS: On average, participants lost 30.15kg (SD: 12.26) after the bariatric intervention. Levels of C-peptide, insulin, CRP, leptin, IL-1Rα, and IL-6 significantly decreased, while levels of SHBG, IGFBP1, and adiponectin significantly increased with weight loss. Normative comparisons showed the levels of SHBG, C-peptide, insulin, IGFBP1, adiponectin, CRP, and TNFα after bariatric intervention approached the level of markers in comparison group. Multiple regression analyses revealed significant relationships between changes in BMI and changes in biomarker levels. The changes in IL-1Rα were significantly associated with race. CONCLUSIONS: Our findings demonstrate that normalization of EC risk biomarkers can be achieved with bariatric surgery. Improved understanding of biological mechanisms associated with weight loss may inform preventive strategies for EC.

RESUMEN

OBJECTIVE: To explore risk factors associated with sampling failure in women who underwent Pipelle biopsy. METHODS: A consecutive sample of 201 patient records was selected from women who underwent Pipelle biopsy procedures for suspected uterine pathology in a large healthcare system over a 6-month period (January 2013 through June 2013). Personal and medical data including age, BMI, gravidity and parity, and previous history of Pipelle biopsy were abstracted from medical records for each patient. Logistic regression analyses were used to determine factors associated with biopsy sampling failure. RESULTS: Pipelle biopsy sampling failed in 46 out 201 women (22.89%), where 8 (17.39%) were due to inability to access the endometrium, 37 (80.43%) were inadequate samples, and 1 (2.18%) was due to unknown reasons. Personal and medical factors found to be related to sampling failure included: postmenopausal bleeding as biopsy indication (OR 7.41, 95% CI 2.27-24.14); history of prior biopsy failure (OR 23.87, 95% CI 3.76-151.61); and provider type (physician vs. midlevel provider) (OR 9.152, 95% CI 2.49-33.69). CONCLUSION: We identified several risk factors for biopsy failure that suggest the need for particular care with Pipelle sampling procedures among women with certain characteristics, including postmenopausal bleeding and a history of prior failed Pipelle biopsy. Our finding of a significantly higher risk of sampling failure based on personal and clinical data suggests that providers must take into account additional considerations to improve sampling success.

RESUMEN

PURPOSE: Postoperative nausea and vomiting (PONV) and post-discharge nausea and vomiting (PDNV) continue to be common and disturbing complications experienced after surgery, particularly in women and especially in women undergoing breast cancer surgery. The purpose of this study was to assess the incidence and risk factors associated with PONV and PDNV from preoperative to 48 hours postoperatively in 97 women scheduled for breast cancer surgery. DESIGN: Prospective, comparative design. METHODS: After informed consent was obtained, women scheduled for breast cancer surgery were evaluated for incidence of vomiting, as well as the presence and severity of nausea from the preoperative holding area for 48 hours following surgery. Vomiting was assessed as both a nominally scaled, binary variable (Yes/No) and as a continuous variable to measure separate emetic events. Nausea was measured on an 11point verbal numeric scale with 0 being the absence of nausea and 10 representing the highest level of nausea ever experienced. RESULTS: Twenty-nine (29.8%) women experienced nausea, and nine (9%) women experienced nausea and vomiting while in the post-anesthesia care unit despite close attention to the need for prophylactic antiemetic medications. Women who experienced PONV had higher levels of pain and received more opioids than those women who did not experience PONV. Women who received intravenous acetaminophen did not experience less PONV in this study. PDNV occurred more frequently than PONV, with 34 women (35%) reporting occurrence after discharge. About 13 women who did not experience PONV while in the PACU subsequently experienced PDNV after leaving the hospital, evidence for the importance of patient discharge teaching regarding these symptoms. Although clinical guidelines are necessary, our observation is that nurses in the PACU setting continuously challenge themselves to individualize the combination of medications and activities for each patient to reduce PONV after surgery.

RESUMEN

Non-adherence to adjuvant endocrine therapy (ET) for breast cancer (BC) is common. Our goal was to determine the associations between psychosocial factors and ET non-persistence. We recruited women with BC receiving care in an integrated healthcare system between 2006 and 2010. Using a subset of patients treated with ET, we investigated factors related to ET non-persistence (discontinuation) based on pharmacy records (≥90 days gap). Serial interviews were conducted at baseline and every 6 months. The Functional Assessment of Cancer Therapy (FACT), Medical Outcomes Survey, Treatment Satisfaction Questionnaire (TSQM), Impact of Events Scale (IES), Interpersonal Processes of Care measure, and Decision-making beliefs and concerns were measured. Multivariate models assessed factors associated with non-persistence. Of the 523 women in our final cohort who initiated ET and had a subsequent evaluation, 94 (18 %) were non-persistent over a 2-year follow-up. The cohort was primarily white (74.4 %), stage 1 (60.6 %), and on an aromatase inhibitor (68.1 %). Women in the highest income category had a lower odds of being non-persistent (OR 0.43, 95 % CI 0.23-0.81). Quality of life and attitudes toward ET at baseline were associated with non-persistence. At follow-up, the FACT, TSQM, and IES were associated with non-persistence (p < 0.001). Most women continued ET. Women who reported a better attitude toward ET, better quality of life, and more treatment satisfaction, were less likely to be non-persistent and those who reported intrusive/avoidant thoughts were more likely to be non-persistent. Interventions to enhance the psychosocial well-being of patients should be evaluated to increase adherence.

RESUMEN

For many women with non-metastatic breast cancer, adjuvant chemotherapy prevents recurrence and extends survival. Women who discontinue chemotherapy early may reduce those benefits, but little is known about what predicts early discontinuation. We sought to determine prospectively the rate and reasons for early discontinuation of adjuvant chemotherapy in women with breast cancer. We conducted a prospective cohort study among three U.S. health care organizations. Of 1158 women with newly diagnosed non-metastatic breast cancer, 2006-2010, we analyzed 445 (38.4 %) patients who initiated standard adjuvant chemotherapy as defined by accepted guidelines. We interviewed patients at baseline and twice during treatment regarding sociodemographic/psychosocial factors and treatment decision-making and collected clinical data. They were categorized according to the number of cycles required by the chemotherapy regimen they had initiated. The outcome was early discontinuation (<80 % of planned cycles). Of patients analyzed, 392 (88.1 %) completed the prescribed therapy. The strongest predictor was receipt of a regimen entailing >4 cycles of therapy (18.1 % for longer regimens, 7.4 % for 4 cycles) (odds ratio [OR] 2.59, 95 % CI 1.32-5.08), controlling for race, age, stage, hormone receptor status, social support, optimism, spirituality, stress, and physical symptoms. Higher levels of psychological symptoms on the Memorial symptom assessment scale also increased the odds of early discontinuation (OR 1.92, 95 % CI 0.998-3.68). The large majority of patients who initiated adjuvant chemotherapy for breast cancer completed their prescribed regimens, but early discontinuation was associated with lengthier regimens and, with borderline statistical significance, for those with psychological side effects.

RESUMEN

PURPOSE: Invasive ductal carcinoma (IDC) is diagnosed with or without a ductal carcinoma in situ (DCIS) component. Previous analyses have found significant differences in tumor characteristics between pure IDC lacking DCIS and mixed IDC with DCIS. We will test our hypothesis that pure IDC represents a form of breast cancer with etiology and risk factors distinct from mixed IDC/DCIS. METHODS: We compared reproductive risk factors for breast cancer risk, as well as family and smoking history between 831 women with mixed IDC/DCIS (n = 650) or pure IDC (n = 181), and 1,620 controls, in the context of the Women's Circle of Health Study (WCHS), a case-control study of breast cancer in African-American and European-American women. Data on reproductive and lifestyle factors were collected during interviews, and tumor characteristics were abstracted from pathology reports. Case-control and case-case analyses were conducted using unconditional logistic regression. RESULTS: Most risk factors were similarly associated with pure IDC and mixed IDC/DCIS. However, among postmenopausal women, risk of pure IDC was lower in women with body mass index (BMI) 25 to <30 [odds ratio (OR) 0.66; 95 % confidence interval (CI) 0.35-1.23] and BMI ≥ 30 (OR 0.33; 95 % CI 0.18-0.67) compared to women with BMI < 25, with no associations with mixed IDC/DCIS. In case-case analyses, women who breastfed up to 12 months (OR 0.55; 95 % CI 0.32-0.94) or longer (OR 0.47; 95 % CI 0.26-0.87) showed decreased odds of pure IDC than mixed IDC/DCIS compared to those who did not breastfeed. CONCLUSIONS: Associations with some breast cancer risk factors differed between mixed IDC/DCIS and pure IDC, potentially suggesting differential developmental pathways. These findings, if confirmed in a larger study, will provide a better understanding of the developmental patterns of breast cancer and the influence of modifiable risk factors, which in turn could lead to better preventive measures for pure IDC, which have worse disease prognosis compared to mixed IDC/DCIS.

RESUMEN

PURPOSE: Nausea is a common and potentially serious effect of cytotoxic chemotherapy for recurrent ovarian cancer and may function as a sentinel symptom reflecting adverse effects on the gut-brain axis (GBA) more generally, but research is scant. As a first exploratory test of this GBA hypothesis, we compared women reporting nausea to women not reporting nausea with regard to the severity of other commonly reported symptoms in this patient population. METHODS: A secondary analysis of data systematically collected from women in active chemotherapy treatment for recurrent ovarian cancer (n = 158) was conducted. The Symptom Representation Questionnaire (SRQ) provided severity ratings for 22 common symptoms related to cancer and chemotherapy. Independent sample t tests and regression analyses were used to compare women with and without nausea with regard to their experience of other symptoms. RESULTS: Nausea was reported by 89 (56.2 %) women. Symptoms that were significantly associated with nausea in bivariate and regression analyses included abdominal bloating, bowel disturbances, dizziness, depression, drowsiness, fatigue, headache, lack of appetite, memory problems, mood swings, shortness of breath, pain, sleep disturbance, urinary problems, vomiting, and weight loss. Symptoms that were not associated with nausea included hair loss, numbness and tingling, sexuality concerns, and weight gain. CONCLUSIONS: Nausea experienced during chemotherapy for recurrent ovarian cancer may be an indicator of broader effects on the gut-brain axis. A better understanding of the mechanisms underlying these effects could lead to the development of novel supportive therapies to increase the tolerability and effectiveness of cancer treatment.
