RESUMO

BACKGROUND: As previous studies showed significant hospital variation in curative treatment of esophagogastric cancer, this study assesses the association between this variation and overall, cancer-specific and recurrence-free survival, and Health-Related Quality of Life (HRQoL). METHODS: Patients diagnosed with potentially curable esophageal or gastric cancer between 2015 and 2018 as registered in the Netherlands Cancer Registry were included. Data on overall survival was available for all patients, data on cancer-specific and recurrence-free survival and HRQoL was available for subgroups. Patients were classified according to diagnosis in hospitals with low, medium or high probability of treatment with curative intent (LP, MP or HP). Multivariable models were used to assess the association between LP, MP and HP hospitals and HRQoL and survival. RESULTS: This study includes 7,199 patients with esophageal, and 2,407 with gastric cancer. Overall and cancer-specific survival was better for patients diagnosed in HP versus LP hospitals for both esophageal (HR = 0.82, 95%CI:0.77-0.88 and HR = 0.82, 95%CI:0.75-0.91, respectively), and gastric cancer (HR = 0.82, 95%CI:0.73-0.92 and HR = 0.74, 95%CI:0.64-0.87, respectively). These differences disappeared after adjustments for treatment. Recurrence-free survival was worse for gastric cancer patients diagnosed in HP hospitals (HR = 1.50, 95%CI:1.14-1.96), which disappeared after adjustment for radicality of surgery. Minor, but no clinically relevant, differences in HRQoL were observed. CONCLUSIONS: Patients diagnosed in hospitals with a high probability of treatment with curative intent have a better overall and cancer-specific but not recurrence-free survival, while minor differences in HRQoL were observed.

RESUMO

PURPOSE: Involved internal iliac and obturator lateral lymph nodes (LLNs) are a known risk factor for the occurrence of ipsilateral local recurrences (LLR) in rectal cancer. This study examined coverage of LLNs with routine radiation therapy practice in the Netherlands and associated LLR rates. METHODS AND MATERIALS: Patients with a primary tumor ≤8 cm of the anorectal junction, cT3-4 stage, and at least 1 internal iliac or obturator LLN with short axis ≥5 mm who received neoadjuvant (chemo)radiation therapy, were selected from a national, cross-sectional study of patients with rectal cancer treated in the Netherlands in 2016. Magnetic resonance images and radiation therapy treatment plans were reviewed regarding segmented LLNs as gross tumor volume (GTV), location of LLNs within clinical target volume (CTV), and received proportion of the planned radiation therapy dose. RESULTS: A total of 223 out of 3057 patients with at least 1 LLN ≥5 mm were selected. Of those, 180 (80.7%) LLNs were inside the CTV, of which 60 (33.3%) were segmented as GTV. Overall, 202 LLNs (90.6%) received ≥95% of the planned dose. Four-year LLR rates were not significantly higher for LLNs situated outside the CTV compared with those inside (4.0% vs 12.5%, P = .092) or when receiving <95% versus ≥95% of the planned radiation therapy dose (7.1% vs 11.3%, P = .843), respectively. Two of 7 patients who received a dose escalation of 60 Gy developed an LLR (4-year LLR rate of 28.6%). CONCLUSIONS: This evaluation of routine radiation therapy practice showed that adequate coverage of LLNs was still associated with considerable 4-year LLR rates. Techniques resulting in better local control for patients with involved LLNs need to be explored further.

RESUMO

PURPOSE: Although various studies have reported that stereotactic body radiation therapy (SBRT) for liver metastases has high local control rates and relatively low toxicity, most series included a small number of patients. We aimed to validate these outcomes in a large multi-institution patient cohort treated in accordance with a common protocol. METHODS AND MATERIALS: A shared web-based registry of patients with liver metastases treated with SBRT was developed by 13 centers (12 in the Netherlands and 1 in Belgium). All the centers had previously agreed on the items to be collected, the fractionation schemes, and the organs-at-risk constraints to be applied. Follow-up was performed at the discretion of the centers. Patient, tumor, and treatment characteristics were entered in the registry. Only liver metastases treated individually as independent targets and with at least 1 radiologic follow-up examination were considered for local control analysis. Toxicity of grade 3 or greater was scored according to the Common Terminology Criteria of Adverse Events (v4.03). RESULTS: Between January 1, 2013, and July 31, 2019, a total of 515 patients were entered in the web-based registry. The median age was 71 years. In total, 668 liver metastases were registered, and 447 were included for local control analysis. The most common primary tumor origin was colorectal cancer (80.3%), followed by lung cancer (8.9%) and breast cancer (4%). The most-used fractionation scheme was 3x18-20 Gy (36.0%), followed by 8x7.5 Gy (31.8%), 5x11-12 Gy (25.5%), and 12x5 Gy (6.7%). The median follow-up time was 1.1 years for local control and 2.3 years for survival. Actuarial 1-year local control was 87%; 1-year overall survival was 84%. Toxicity of grade 3 or greater was found in 3.9% of the patients. CONCLUSIONS: This multi-institutional study confirms the high rates of local control and limited toxicity in a large patient cohort. Stereotactic body radiation therapy should be considered a valuable part of the multidisciplinary approach to treating liver metastases.

RESUMO

Objective: Advanced non-small cell lung cancer (NSCLC) is common, deadly, and associated with impairing anxiety for patients and caregivers who often co-experience similar symptoms that can vary together over time. We aimed to discover themes as to how NSCLC patients and caregivers express and cope with anxiety. Design: Semi-structured interviews of patient-caregiver dyads (N = 21), coded using NVivo Software. Main Outcome Measures: Open-ended questions on anxiety mutuality, giving or receiving care, communication, and the most difficult aspects of having or caring for someone with Stage IV NSCLC. Results: Analyses revealed that patients and caregivers were linked psychologically, co-experiencing symptoms of distress or coping, rising and falling together. Shared patient and caregiver themes emerged of cognitive, behavioural and physiological manifestations of anxiety and coping mechanisms. Conclusions: Patient and caregiver expressions of anxiety and coping methods mapped onto the cognitive-behavioural model, implying potential use of cognitive behavioural therapy (CBT) to address these issues. This expands understanding of symptoms and coping strategies in NSCLC, explores patient-caregiver interaction, and confirms the need for future clinical intervention. Future research should focus on development and dissemination of CBT-based dyadic interventions addressing anxiety in NSCLC patients and caregivers.

RESUMO

BACKGROUND AND OBJECTIVES: Minimally invasive esophagectomy is emerging with comparable short-term outcomes as open esophagectomies. Neoadjuvant chemoradiotherapy followed by surgery is considered standard of care in the Netherlands for patients with esophageal cancer. The aim of this study was to analyze the long-term oncologic outcome after neoadjuvant chemoradiotherapy followed by totally minimally invasive esophagectomy. METHODS: Neoadjuvant carboplatin and paclitaxel based chemotherapy was concomitantly given with 41.4 Gy radiotherapy. Six weeks after neoadjuvant treatment, totally minimally invasive esophagectomy was performed. RESULTS: From December 2010 until December 2015 161 patients received this combination of treatment. In 128 male and 33 female patients with median age of 65 years (58-71), 88 minimally invasive esophagectomies with intrathoracic anastomosis and 73 minimally invasive esophagectomies with cervical anastomosis were carried out. Radical (R0) resection was confirmed in 156 patients (97%). In hospital mortality occurred in 6 patients (3.7%). Overall survival was 79% and 51% at 1 and 5 years, respectively, with a median follow-up of 24.5 months (13-38). Disease-free survival was, respectively, 76% and 55%. CONCLUSIONS: Totally minimally invasive esophagectomy after neoadjuvant chemoradiotherapy for esophageal cancer is a safe treatment with low postoperative mortality rates and favorable overall and disease-free survival.

RESUMO

An important problem in minimally invasive photoacoustic (PA) imaging of brachytherapy seeds is reflection artifacts caused by the high signal from the optical fiber/needle tip reflecting off the seed. The presence of these artifacts confounds interpretation of images. In this letter, we demonstrate a recently developed concept called photoacoustic-guided focused ultrasound (PAFUSion) for the first time in the context of interstitial illumination PA imaging to identify and remove reflection artifacts. In this method, ultrasound (US) from the transducer is focused on the region of the optical fiber/needle tip identified in a first step using PA imaging. The image developed from the US diverging from the focus zone at the tip region visualizes only the reflections from seeds and other acoustic inhomogeneities, allowing identification of the reflection artifacts of the first step. These artifacts can then be removed from the PA image. Using PAFUSion, we demonstrate reduction of reflection artifacts and thereby improved interstitial PA visualization of brachytherapy seeds in phantom and

RESUMO

Although studies consistently report high rates of comorbid posttraumatic stress disorder (PTSD) and HIV infection, development and testing of PTSD treatment interventions in HIV-infected adults is limited. As such, the purpose of this review was twofold. First, this review augments the three existing reviews of research for PTSD in HIV-infected adults conducted within the past 10 years. We found two empirically supported cognitive-behavioral therapy-based interventions for the treatment of trauma-related symptoms in HIV-infected adults. Due to the continued limited number of effective interventions for this population, a second aim of our review was to draw from the expansive field of effective PTSD interventions for the general population to propose ways that future clinical intervention research may be tailored for HIV-infected adults. Therefore, in addition to a review, we conceptualized this paper as an opportunity to generate an ideal preview of the field of intervention research in this population.

RESUMO

PURPOSE OF REVIEW: Existential distress is well documented among patients at end of life (EOL) and increasingly recognized among informal caregivers. However, less information is known about existential concerns among healthcare providers working with patients at EOL, and the impact that such concerns may have on professionals. RECENT FINDINGS: Recent literature documents five key existential themes for professionals working in EOL care: (1) opportunity for introspection; (2) death anxiety and potential to compromise patient care; (3) risk factors and negative impact of existential distress; (4) positive effects such as enhanced meaning and personal growth; and (5) the importance of interventions and self-care. SUMMARY: EOL work can be taxing, yet also highly rewarding. It is critical for healthcare providers to make time for reflection and prioritize self-care in order to effectively cope with the emotional, physical, and existential demands that EOL care precipitates.

RESUMO

PURPOSE: Anxiety is prevalent, distressing, and understudied among patients with advanced lung cancer and their family caregivers. Preliminary evidence suggests that anxiety is not only present in both patients and caregivers but shared by the dyad. Few studies have examined the nature of shared anxiety and its impact on patient-caregiver dyads. METHODS: This study was developed to identify shared causes and manifestations of anxiety experienced by patients with stage IV non-small cell lung cancer (NSCLC) and their primary caregivers. Data were collected through in-depth semi-structured interviews with ten matched patient-caregiver dyads and one unmatched patient (N = 21) recruited from two comprehensive cancer care centers. RESULTS: Using grounded theory, eight themes emerged characterizing shared causes and manifestations of anxiety: (1) uncertainty, (2) loss and impending loss, (3) changing roles, (4) conflict outside the dyad, (5) finances, (6) physical symptoms, (7) fears of decline and dying, and (8) life after the patient's passing. All themes were shared by patients and caregivers. CONCLUSIONS: Implications for future research include the development and evaluation of interventions to reduce anxiety in cancer patient-caregiver dyads.

RESUMO

INTRODUCTION: Patients with terminal cancer often experience marked anxiety that is associated with poor quality of life. Although cognitive-behavioral therapy (CBT) is an evidence-based treatment for anxiety disorders, the approach needs to be adapted to address realistic concerns related to having cancer, such as worries about disease progression, disability, and death. In this pilot randomized controlled trial (clinicaltrials.gov identifier NCT00706290), we examined the feasibility and potential efficacy of brief CBT to reduce anxiety in patients with terminal cancer. METHODS: We adapted CBT by developing treatment modules targeting skills for relaxation, coping with cancer worries, and activity pacing. Adults with incurable malignancies and elevated anxiety based on the Hamilton Anxiety Rating Scale (HAM-A) were randomly assigned to individual CBT or a waitlist control group. Primary outcomes included the number of completed CBT visits and the change in HAM-A scores from baseline to 8-week follow-up per a treatment-blind evaluator. The feasibility criterion was 75% adherence to the intervention. RESULTS: We randomized 40 patients with terminal cancers to CBT (n = 20) or waitlist control (n = 20) groups; 70% completed posttreatment assessments. Most patients who received CBT (80%) participated in at least five of the required six therapy sessions. Analysis of covariance models, adjusted for baseline scores, showed that those assigned to CBT had greater improvements in HAM-A scores compared to the control group, with an adjusted mean difference of -5.41 (95% confidence interval: -10.78 to -0.04) and a large effect size for the intervention (Cohen's d = 0.80). CONCLUSION: Providing brief CBT tailored to the concerns of patients with terminal cancer was not only feasible but also led to significant improvements in anxiety.

RESUMO

As Antiretroviral Therapy (ART) is scaled up in low- and middle-income countries, it is important to understand Quality of Life (QOL) correlates including disease severity and person characteristics and to determine the extent of between-country differences among those with HIV. QOL and medical data were collected from 1,563 of the 1,571 participants at entry into a randomized clinical trial of ART conducted in the U.S. (n = 203) and 8 resource-limited countries (n = 1,360) in the Caribbean, South America, Asia, and Africa. Participants were interviewed prior to initiation of ART using a modified version of the ACTG SF-21, a health-related QOL measure including 8 subscales: general health perception, physical functioning, role functioning, social functioning, cognitive functioning, pain, mental health, and energy/fatigue. Other measures included demographics, CD4+ lymphocyte count, plasma HIV-1 RNA viral load. Higher quality of life in each of the 8 QOL subscales was associated with higher CD4+ lymphocyte category. General health perception, physical functioning, role functioning, and energy/fatigue varied by plasma HIV-1 RNA viral load categories. Each QOL subscale included significant variation by country. Only the social functioning subscale varied by sex, with men having greater impairments than women, and only the physical functioning subscale varied by age category. This was the first large-scale international ART trial to conduct a standardized assessment of QOL in diverse international settings, thus demonstrating that implementation of the behavioral assessment was feasible. QOL indicators at study entry varied with disease severity, demographics, and country. The relationship of these measures to treatment outcomes can and should be examined in clinical trials of ART in resource-limited settings using similar methodologies.

RESUMO

BACKGROUND: As each HIV-infected individual represents a breakdown of HIV primary prevention measures, formative data from representative individuals living with HIV can help shape future primary prevention interventions. Little is known about sexual behaviours and other transmission risk factors of high-risk group members who are already HIV-infected in Chennai, India. METHODS: Semi-structured qualitative interviews were conducted with 27 HIV-infected individuals representing each high-risk group in Chennai (five men who have sex with men (MSM), five female commercial sex workers (CSW), four truckers and other men who travel for business, four injecting drug users (IDU), five married male clients of CSW, and four wives of CSW clients, MSM, truckers, and IDU). RESULTS: Themes relevant to HIV primary prevention included: (1) HIV diagnosis as the entry into HIV education and risk reduction, (2) reluctance to undergo voluntary counselling and testing, (3) gender and sexual roles as determinants of condom use, (4) misconceptions about HIV transmission, and (5) framing and accessibility of HIV education messages. CONCLUSIONS: These qualitative data can be used to develop hypotheses about sexual risk taking in HIV-infected individuals in South India, inform primary prevention intervention programs, and improve primary prevention efforts overall.

RESUMO

Childhood sexual abuse (CSA) is related to poorer health outcomes, associated with increased risk for HIV acquisition, and prevalent among HIV risk groups. Links between CSA and health behavior are an important health concern. We examined the relationship between CSA and transmission risk behavior and medication adherence in 119 HIV-infected individuals with an injection drug use history. 47% reported CSA, with no gender difference. Individuals who experienced CSA were more likely to report sexual HIV transmission risk behavior in the past 6 months, more sexual partners, use of heroin in the past 30 days, and worse adherence to HIV medication than those who did not. These findings confirm that rates of CSA are high in this population, and suggest that a history of CSA may place people managing both HIV and opioid dependence at increased risk for HIV transmission, poor adherence to medication, and vulnerability to substance use relapse.

RESUMO

Informal, interpersonal communication within a community about HIV and AIDS, or lack of such communication, may influence community members' uptake of voluntary counseling and testing. Drawing from Noelle-Neumann's spiral of silence theory, this study examined the association between communication about HIV/AIDS and prior HIV testing in communities in Tanzania, Zimbabwe, South Africa, and Thailand. Participants (N = 14,818) in 48 communities across five sites throughout the four countries completed a behavioral survey assessing communication, prior voluntary counseling and testing (VCT) uptake, social norms, stigma, and sexual risk. Site-specific logistic regression models demonstrated that frequent conversations about HIV were significantly associated with prior HIV testing at every site. Odds ratios for each site ranged from 1.885 to 3.085, indicating a roughly doubled or tripled chance of past VCT uptake. Results indicate that verbal communication may be an important mechanism for increasing health behaviors and inclusion in future interventions should be considered.

RESUMO

Latinos maintain an AIDS case rate more than 3 times higher than whites, a greater rate of progression to AIDS, and a higher rate of HIV/AIDS-related deaths. Three broad areas are reviewed related to these disparities: (1) relevant demographic, socioeconomic, and socio-cultural factors among Latinos; (2) drug abuse and mental health problems in Latinos relevant to HIV/AIDS outcomes; and (3) opportunities for psychosocial intervention. Latinos living with HIV are a rapidly growing group, are more severely impacted by HIV than whites, and confront unique challenges in coping with HIV/AIDS. A body of research suggests that depression, substance abuse, treatment adherence, health literacy, and access to healthcare may be fruitful targets for intervention research in this population. Though limited, the current literature suggests that psychosocial interventions that target these factors could help reduce HIV/AIDS disparities between Latinos and whites and could have important public health value.

RESUMO

Formative data on the sexual behaviors of HIV-infected individuals in regions disproportionately affected by the epidemic can help generate hypotheses about sexual risk taking in HIV-infected individuals and shape interventions to prevent further transmission. India is home to the highest number of HIV-infected individuals in the world, and very little information is available about the sexual behaviors of HIV-infected Indians. The present qualitative study presents themes from individual in-depth interviews with 30 HIV-infected individuals in South India. The sample included individuals from demographic groups that may experience different risk factors (five individuals each: from men who have sex with men, sex workers, married men, married women, injection drug users, and truck drivers ormen who travel for work). Across the groups, the three most frequently discussed themes involved (a) sexual behavior change (sexual risk reduction after HIV diagnosis, sexual behavior remaining safe after initiation of ART treatment), (b) motivations to reduce risk (motivation to protect one's self against further infection, to protect others from infection), and (c) barriers to reduce risk (complexity and stigma associated with condom negotiation, perception of HIV-infected peers being less concerned about protecting others, condom use as linked to gender and sexual roles, condom use as inconvenient or unappealing). This qualitative data can be used to generate hypotheses about sexual risk taking in HIV-infected individuals in South India, to inform models of risky behaviors of HIV-infected individuals for quantitative studies, and to lay the groundwork for secondary prevention intervention efforts that enhance facilitators and reduce barriers of safer sex articulated by the interviewees.

RESUMO

OBJECTIVES: We examined correlates of condom use among a national random probability sample of sexually experienced young adults aged 15 to 24 years (n = 7686) in South Africa. METHODS: Using data from the Reproductive Health and HIV Research Unit National Youth Survey, we conducted gender-stratified bivariate and multivariate logistic regression analyses to determine predictors of whether respondents had used a condom during their most recent sexual intercourse. RESULTS: Condom use at sexual debut and talking with one's first sexual partner about condoms were the most significant predictors of condom use at most recent intercourse. Other significant predictors included high condom use self-efficacy, optimism about the future, and reported behavior change attributable to HIV/AIDS. Young adults who were married or had been involved in a relationship for 6 months or more were significantly less likely to have used a condom during their most recent sexual intercourse. CONCLUSIONS: Our findings point to the importance of exposing youths to sexuality education before their sexual debut as well as voluntary counseling and testing and programming that supports young adults, particularly young women, in making informed decisions about sexual intercourse and condoms.

RESUMO

OBJECTIVES: To use logistic regression modeling to identify factors associated with high self-efficacy for sexual negotiation and condom use in a sample of South African youth. METHODS: The Reproductive Health and HIV Research Unit (RHRU) National Youth Survey examined a nationally representative sample of 7409 sexually active South African youth aged 15 to 24 years. We used logistic regression modeling in this sample to identify factors associated with the main outcome of high self-efficacy. RESULTS: Among female respondents (n = 3890), factors associated with high self-efficacy in the adjusted model were knowing how to avoid HIV (odds ratio [OR] = 2.30, 95% confidence interval [CI]: 1.05 to 5.00), having spoken with someone other than a parent or guardian about HIV/AIDS (OR = 1.46, 95% CI: 1.01 to 2.10), and having life goals (OR = 1.28, 95% CI: 1.10 to 1.48). Not using condoms during their first sexual encounter (OR = 0.61, 95% CI: 0.50 to 0.76), a history of unwanted sex (OR = 0.66, 95% CI: 0.51 to 0.86), and believing that condom use implies distrust in one's partner (OR = 0.57, 95% CI: 0.51 to 0.86) were factors associated with low self-efficacy among female respondents. Male respondents (n = 3519) with high self-efficacy were more likely to take HIV seriously (OR = 4.03, 95% CI: 1.55 to 10.52), to believe they are not at risk for HIV (OR = 1.38, 95% CI: 1.12 to 1.70), to report that getting condoms is easy (OR = 1.85, 95% CI: 1.23 to 2.77), and to have life goals (OR = 1.30, 95% CI: 1.10 to 1.54). Not using condoms during their first sexual experience (OR = 0.51, 95% CI: 0.39 to 0.67), a history of having unwanted sex (OR = 0.47, 95% CI: 0.34 to 0.64), believing condom use is a sign of not trusting one's partner (OR = 0.63, 95% CI: 0.46 to 0.87), and refusing to be friends with HIV-infected persons (OR = 0.52, 95% CI: 0.32 to 0.85) were factors associated with low self-efficacy among male respondents in the fully adjusted model. CONCLUSIONS: We used the social cognitive model (SCM) to identify factors associated with self-efficacy for condom use and sexual negotiation. Many of these factors are modifiable and suggest potential ways to improve self-efficacy and reduce HIV sexual risk behavior in South African youth.

RESUMO

The present study examined the frequency and correlates of self-reported symptoms of posttraumatic stress among patients with HIV and medication adherence problems. Self-report data revealed that more than half of participants met diagnostic criteria for posttraumatic stress disorder (PTSD) according to the Posttraumatic Diagnostic Scale PDS. Death anxiety was associated with overall PTSD symptom severity scores as well as severity scores for reexperiencing, avoidance, and arousal symptoms. The association between death anxiety and total PTSD severity, reexperiencing and avoidance symptom scores remained after controlling for depression and satisfaction with social support. Anxiety, as manifested by PTSD symptoms should be routinely assessed among patients with HIV, and variables such as death anxiety, social support, and depression are appropriate targets for mental health interventions.
