RESUMO

BACKGROUND AND AIMS: Liver fibrosis is common in children with NAFLD and is an important determinant of outcomes. High-performing noninvasive models to assess fibrosis in children are needed. The objectives of this study were to evaluate the performance of existing pediatric and adult fibrosis prediction models and to develop a clinical prediction rule for identifying moderate-to-severe fibrosis in children with NAFLD. APPROACH AND RESULTS: We enrolled children with biopsy-proven NAFLD in the Nonalcoholic Steatohepatitis Clinical Research Network within 90 days of liver biopsy. We staged liver fibrosis in consensus using the Nonalcoholic Steatohepatitis Clinical Research Network scoring system. We evaluated existing pediatric and adult models for fibrosis and developed a new pediatric model using the least absolute shrinkage and selection operator with linear and spline terms for discriminating moderate-to-severe fibrosis from none or mild fibrosis. The model was internally validated with 10-fold cross-validation. We evaluated 1055 children with NAFLD, of whom 26% had moderate-to-severe fibrosis. Existing models performed poorly in classifying fibrosis in children, with area under the receiver operator curves (AUC) ranging from 0.57 to 0.64. In contrast, our new model, fibrosis in pediatric NAFLD was derived from fourteen common clinical variables and had an AUC of 0.79 (95% CI: 0.77-0.81) with 72% sensitivity and 76% specificity for identifying moderate-to-severe fibrosis. CONCLUSION: Existing fibrosis prediction models have limited clinical utility in children with NAFLD. Fibrosis in pediatric NAFLD offers improved performance characteristics for risk stratification by identifying moderate-to-severe fibrosis in children with NAFLD.

RESUMO

BACKGROUND: Cancer antigen 19-9 (CA19-9) is widely used as a marker of pancreatic cancer tumor burden and response to therapy. Synthesis of CA19-9 and its circulating levels are determined by variants encoding the fucosyltransferases, FUT2 and FUT3. Individuals can be grouped into one of four functional FUT groups (FUT3-null, FUT-low, FUT-intermediate, FUT-high), each with its own CA19-9 reference range based on its predicted capacity to produce CA19-9. The authors hypothesized that a FUT variant-based CA19-9 tumor marker gene test could improve the prognostic performance of CA19-9. METHODS: Preoperative and pre-treatment CA19-9 levels were measured, and FUT variants were determined in 449 patients who underwent surgery for pancreatic ductal adenocarcinoma (PDAC) at Johns Hopkins Hospital between 2010 and 2020, including 270 patients who underwent neoadjuvant therapy. Factors associated with recurrence-free and overall survival were determined in Cox proportional hazards models. RESULTS: Higher preoperative CA19-9 levels were associated with recurrence and mortality for patients in the higher-FUT groups (FUT-intermediate, FUT-high for mortality, with adjustment for other prognostic factors; hazard ratio [HR], 1.34 and 1.58, respectively; P < 0.001), but not for those in the lower-FUT groups (FUT3-null, FUT-low). As a tumor marker, CA19-9 levels of 100 U/ml or lower after neoadjuvant therapy and normalization of CA19-9 based on FUT group were more sensitive but less specific predictors of evidence for a major pathologic response to therapy (little/no residual tumor) and of early recurrence (within 6 months). CONCLUSION: Among patients undergoing pancreatic cancer resection, a CA19-9 tumor marker gene test modestly improved the prognostic performance of CA19-9.

RESUMO

Substantial gaps in national healthcare spending and disparities in cancer mortality rates are noted across counties in the US. In this cross-sectional analysis, we investigated whether differences in local county-level social vulnerability impacts cancer-related mortality. We linked county-level age-adjusted mortality rates (AAMR) from the Centers for Disease Control and Prevention (CDC) Wide-ranging Online Data for Epidemiologic Research database, to county-level Social Vulnerability Index (SVI) from the CDC Agency for Toxic Substances and Disease Registry. SVI is a metric comprising 15 social factors including socioeconomic status, household composition and disability, minority status and language, and housing type and transportation. AAMRs were compared between least and most vulnerable counties using robust linear regression models. There were 4 107 273 deaths with an overall AAMR of 173 per 100 000 individuals. Highest AAMRs were noted in older adults, men, non-Hispanic Black individuals, and rural and Southern counties. Highest mortality risk increases between least and most vulnerable counties were noted in Southern and rural counties, individuals aged 45-65, and lung and colorectal cancers, suggesting that these groups may face highest risk for health inequity. These findings inform ongoing deliberations in public health policy at the state and federal level and encourage increased investment into socially disadvantaged counties.

RESUMO

We performed a secondary analysis of the Moving To Opportunity (MTO) social experiment to investigate the impact of different types of housing assistance and neighborhood environments on long-term patterns of health care use for specific conditions and across different types of health care services. MTO participants, who were randomized at baseline, were linked to up to 21 years of all-payer hospital discharge and Medicaid data. Among the 9,170 children at the time of randomization, those who received a voucher had subsequent hospital admissions rates that were 36% lower for asthma and 30% lower for mental health disorders compared to the control group; rates of psychiatric services, outpatient hospital services, clinic services and durable medical equipment were also lower among the voucher groups. Findings for adults were not statistically significant. The results suggest that housing policies that reduce neighborhood poverty exposure as a child are associated with lower subsequent healthcare use for specific clinical conditions and types of services.

RESUMO

BACKGROUND AND AIMS: Serum diagnostic markers of early-stage pancreatic ductal adenocarcinoma (PDAC) are needed, especially for stage I disease. As tumors grow and cause pancreatic atrophy, markers derived from pancreatic parenchyma such as serum carboxypeptidase A (CPA) activity lose diagnostic performance. We evaluated, with CA19-9, serum CPA as a marker of early pancreatic cancer. METHODS: Serum CPA activity levels were measured in 345 controls undergoing pancreatic surveillance, divided into 2 sets, set 1 being used to establish a reference range. Variants within the CPA1 locus were sought for their association with pancreatic CPA1 expression to determine if such variants associated with serum CPA levels. A total of 190 patients with resectable PDAC were evaluated. RESULTS: Among controls, those having 1 or more minor alleles of CPA1 variants rs6955723 or rs2284682 had significantly higher serum CPA levels than did those without (P = .001). None of the PDAC cases with pancreatic atrophy had an elevated CPA. Among 122 PDAC cases without atrophy, defining serum CPA diagnostic cutoffs by a subject's CPA1 variants yielded a diagnostic sensitivity of 18% at 99% specificity (95% confidence interval [CI], 11.7-26) (vs 11.1% sensitivity using a uniform diagnostic cutoff); combining CPA with variant-stratified CA19-9 yielded a sensitivity of 68.0% (95% CI, 59.0-76.2) vs 63.1% (95% CI, 53.9- 71.7) for CA19-9 alone; and among stage I PDAC cases, diagnostic sensitivity was 51.9% (95% CI, 31.9-71.3) vs 37.0% (95% CI, 19.4-57.6) for CA19-9 alone. In the validation control set, the variant-stratified diagnostic cutoff yielded a specificity of 98.2%. CONCLUSION: Serum CPA activity has diagnostic utility before the emergence of pancreatic atrophy as a marker of localized PDAC, including stage I disease.

RESUMO

PURPOSE: Sexual function problems are common but under-reported among women receiving adjuvant endocrine therapy for breast cancer. Worsening scores on patient-reported outcomes (PROs) may identify those at risk for sexual function problems during treatment. We performed a secondary analysis of prospectively collected PROs in women receiving adjuvant endocrine therapy to identify factors associated with worsening sexual function. METHODS: Women with stage 0-III breast cancer initiating adjuvant endocrine therapy participating in a prospective cohort completed PROs at baseline, 3, 6, 12, 24, 36, 48, and 60 months. Sexual function was evaluated by the MOS-SP measure. Other measures included PROMIS pain interference, fatigue, depression, anxiety, physical function, and sleep disturbance and the Endocrine Symptom Subscale of the FACT-ES. We evaluated associations between score worsening of at least the minimal important difference (MID) in PROMIS T-scores (4 points) and FACT-ES scores (5 points) with score worsening of at least the MID in MOS-SP scores (8 points) using logistic regression. RESULTS: Among 300 participants, 45.7% experienced ≥ 8-point worsening of MOS-SP score at any time point compared to baseline. Worsening endocrine symptoms (OR 1.34, 95% CI 1.22-1.49, p < 0.001), worsening physical function (OR 1.09, 95% CI 1.00-1.18, p = 0.06), and prior mastectomy (OR 1.45, 95% CI 0.94-2.23, p = 0.09) were associated with MOS-SP score worsening by at least the MID. CONCLUSION: Worsening endocrine symptoms and physical function identified on PROs are associated with worsening sexual function during adjuvant endocrine therapy. Routine assessment of these domains with PROs may identify women at risk for sexual function problems. TRIAL REGISTRATION NUMBER: NCT01937052; Date of Registration: 09/09/2013.

RESUMO

PURPOSE: Models used to predict the probability of an individual having a pathogenic homozygous or heterozygous variant in a mismatch repair gene, such as MMRpro, are widely used. Recently, MMRpro was updated with new colorectal cancer penetrance estimates. The purpose of this study was to evaluate the predictive performance of MMRpro and other models for individuals with a family history of colorectal cancer. METHODS: We performed a validation study of 4 models, Leiden, MMRpredict, PREMM5, and MMRpro, using 784 members of clinic-based families from the United States. Predicted probabilities were compared with germline testing results and evaluated for discrimination, calibration, and predictive accuracy. We analyzed several strategies to combine models and improve predictive performance. RESULTS: MMRpro with additional tumor information (MMRpro+) and PREMM5 outperformed the other models in discrimination and predictive accuracy. MMRpro+ was the best calibrated with an observed to expected ratio of 0.98 (95% CI = 0.89-1.08). The combination models showed improvement over PREMM5 and performed similar to MMRpro+. CONCLUSION: MMRpro+ and PREMM5 performed well in predicting the probability of having a pathogenic homozygous or heterozygous variant in a mismatch repair gene. They serve as useful clinical decision tools for identifying individuals who would benefit greatly from screening and prevention strategies.

RESUMO

Short telomeres have been linked to cancer risk, yet other evidence supports them being tumor suppressive. Here, we report cancer outcomes in individuals with germline mutations in telomerase and other telomere-maintenance genes. Among 180 individuals evaluated in a hospital-based setting, 12.8% had cancer. Solid tumors were rare (2.8%); nearly all were young male DKC1 mutation carriers, and they were generally resectable with good short-term outcomes. Myelodysplastic syndrome (MDS) was most common, followed by acute myeloid leukemia (AML); they accounted for 75% of cancers. Age over 50 years was the biggest risk factor, and MDS/AML usually manifested with marrow hypoplasia and monosomy 7, but the somatic mutation landscape was indistinct from unselected patients. One- and 2-year survival were 61% and 39%, respectively, and two-thirds of MDS/AML patients died of pulmonary fibrosis and/or hepatopulmonary syndrome. In one-half of the cases, MDS/AML patients showed a recurrent peripheral blood pattern of acquired, granulocyte-specific telomere shortening. This attrition was absent in age-matched mutation carriers who did not have MDS/AML. We tested whether adult short telomere patients without MDS/AML also had evidence of clonal hematopoiesis of indeterminate potential-related mutations and found that 30% were affected. These patients also primarily suffered morbidity from pulmonary fibrosis during follow-up. Our data show that the Mendelian short telomere syndromes are associated with a relatively narrow cancer spectrum, primarily MDS and AML. They suggest that short telomere length is sufficient to drive premature age-related clonal hematopoiesis in these inherited disorders.

RESUMO

BACKGROUND: Survivorship care plans (SCP) should outline pertinent information about cancer treatment and follow-up. METHODS: We descriptively analyzed the content of 74 colorectal cancer SCPs completed as part of a randomized, controlled trial of SCPs at an academic and community cancer center. Surveillance recommendations were compared with American Cancer Society, American Society of Clinical Oncology and National Comprehensive Cancer Network guidelines. RESULTS: SCP information provided in >80% of the plans included participant age, cancer diagnosis, details, and side-effects of treatment (surgery, chemotherapy, radiation) and health promotion recommendations. SCP content documented less frequently included predisposing conditions, genetic counseling/testing information and staging. Posttreatment surveillance recommendations were documented in >90% SCPs. For stage 2-3 cancer, rates of guideline concordant recommendations were 100% for colonoscopy surveillance (Year 1 only), 87% for imaging surveillance, 65% for carcinoembryonic antigen surveillance, and 33% for follow-up visits. Excluding colonoscopy, >15 unique recommendations were listed for each modality across stages and sites, with more variation at the academic site. CONCLUSIONS: SCPs consistently recorded information about cancer diagnosis and treatment but omitted critical information about cancer-specific details denoting risk. Surveillance recommendations varied considerably between cancer centers. Future work to improve the consistency of surveillance recommendations documented in SCPs may be needed.

RESUMO

PURPOSE: PRO-cision medicine refers to personalizing care using patient-reported outcomes (PROs). We developed and feasibility-tested a PRO-cision Medicine remote PRO monitoring intervention designed to identify symptoms and reduce the frequency of routine in-person visits. METHODS: We conducted focus groups and one-on-one interviews with metastatic breast (n = 15) and prostate (n = 15) cancer patients and clinicians (n = 10) to elicit their perspectives on a PRO-cision Medicine intervention's design, value, and concerns. We then feasibility-tested the intervention in 24 patients with metastatic breast cancer over 6-months. We obtained feedback via end-of-study surveys (patients) and interviews (clinicians). RESULTS: Focus group and interview participants reported that remote PRO symptom reporting could alert clinicians to issues and avoid unneeded/unwanted visits. However, some patients did not perceive avoiding visits as beneficial. Clinicians were concerned about workflow. In the feasibility-test, 24/236 screened patients (10%) enrolled. Many patients were already being seen less frequently than monthly (n = 97) or clinicians did not feel comfortable seeing them less frequently than monthly (n = 31). Over the 6-month study, there were 75 total alerts from 392 PRO symptom assessments (average 0.19 alert/assessment). Patients had an average of 4 in-person visits (vs. expected 6.5 without the intervention). Patients (n = 19/24) reported high support on the end-of-study survey, with more than 80% agreeing with positive statements about the intervention. Clinician end-of-study interviews (n = 11/14) suggested that PRO symptom monitoring be added to clinic visits, rather than replacing them, and noted the increasing role of telemedicine. CONCLUSIONS: Future research should explore combining remote PRO symptom monitoring with telemedicine and in-person visits.

RESUMO

BACKGROUND: Vitamin D supplementation may prevent falls in older persons, but evidence is inconsistent, possibly because of dosage differences. OBJECTIVE: To compare the effects of 4 doses of vitamin D3 supplements on falls. DESIGN: 2-stage Bayesian, response-adaptive, randomized trial. (ClinicalTrials.gov: NCT02166333). SETTING: 2 community-based research units. PARTICIPANTS: 688 participants, aged 70 years and older, with elevated fall risk and a serum 25-hydroxyvitamin D [25-(OH)D] level of 25 to 72.5 nmol/L. INTERVENTION: 200 (control), 1000, 2000, or 4000 IU of vitamin D3 per day. During the dose-finding stage, participants were randomly assigned to 1 of the 4 vitamin D3 doses, and the best noncontrol dose for preventing falls was determined. After dose finding, participants previously assigned to receive noncontrol doses received the best dose, and new enrollees were randomly assigned to receive 200 IU/d or the best dose. MEASUREMENTS: Time to first fall or death over 2 years (primary outcome). RESULTS: During the dose-finding stage, the primary outcome rates were higher for the 2000- and 4000-IU/d doses than for the 1000-IU/d dose, which was selected as the best dose (posterior probability of being best, 0.90). In the confirmatory stage, event rates were not significantly different between participants with experience receiving the best dose (events and observation time limited to the period they were receiving 1000 IU/d; n = 308) and those randomly assigned to receive 200 IU/d (n = 339) (hazard ratio [HR], 0.94 [95% CI, 0.76 to 1.15]; P = 0.54). Analysis of falls with adverse outcomes suggested greater risk in the experience-with-best-dose group versus the 200-IU/d group (serious fall: HR, 1.87 [CI, 1.03 to 3.41]; fall with hospitalization: HR, 2.48 [CI, 1.13 to 5.46]). LIMITATIONS: The control group received 200 IU of vitamin D3 per day, not a placebo. Dose finding ended before the prespecified thresholds for dose suspension and dose selection were reached. CONCLUSION: In older persons with elevated fall risk and low serum 25-(OH)D levels, vitamin D3 supplementation at doses of 1000 IU/d or higher did not prevent falls compared with 200 IU/d. Several analyses raised safety concerns about vitamin D3 doses of 1000 IU/d or higher. PRIMARY FUNDING SOURCE: National Institute on Aging.

RESUMO

BACKGROUND: Survivorship care plans contain important information for patients and primary care physicians regarding appropriate care for cancer survivors after treatment. We describe the completeness of prostate cancer survivorship care plans and evaluate the concordance of follow-up recommendations with guidelines. METHODS: We analyzed 119 prostate cancer survivorship care plans from one academic and one community cancer center, abstracting demographics, cancer/treatment details, and follow-up recommendations. Follow-up recommendations were compared with the American Cancer Society (ACS), American Society of Clinical Oncology (ASCO), and National Comprehensive Cancer Network (NCCN) guidelines. RESULTS: Content in >90% of plans included cancer TNM stage; prostate-specific antigen (PSA) at diagnosis; radiation treatment details (98% of men received radiation); and PSA monitoring recommendations. Potential treatment-specific side effects were listed for 82% of men who had surgery, 86% who received androgen deprivation therapy (ADT), and 97% who underwent radiation. The presence of posttreatment symptoms was noted in 71% of plans. Regarding surveillance follow-up, all guidelines recommend an annual digital rectal exam (DRE). No plans specified DRE. However, all 71 plans at the community site recommended at least annual follow-up visits with urology, radiation oncology, and primary care. Only 2/48 plans at the academic site specified follow-up visits. All guidelines recommend PSA testing every 6-12 months for 5 years, then annually. For the first 5 years, 90% of plans were guideline-concordant, 8% suggested oversurveillance, and 2% were incomplete. In men receiving ADT, ACS and ASCO recommend bone density imaging and NCCN recommends testosterone levels. Of 77 men on ADT, 1% were recommended bone density imaging and 16% testosterone level testing. CONCLUSIONS: While care plan content is more complete for demographic and treatment summary information, both sites had gaps in reporting posttreatment symptoms and ADT-related testing recommendations. These findings highlight the need to improve the quality of information in care plans, which are important in communicating appropriate follow-up recommendations to patients and primary care physicians.

RESUMO

INTRODUCTION: Identifying families with an underlying inherited cancer predisposition is a major goal of cancer prevention efforts. Mendelian risk models have been developed to better predict the risk associated with a pathogenic variant of developing breast/ovarian cancer (with BRCAPRO) and the risk of developing pancreatic cancer (PANCPRO). Given that pathogenic variants involving BRCA2 and BRCA1 predispose to all three of these cancers, we developed a joint risk model to capture shared susceptibility. METHODS: We expanded the existing framework for PANCPRO and BRCAPRO to jointly model risk of pancreatic, breast, and ovarian cancer and validated this new model, BRCAPANCPRO on three data sets each reflecting the common target populations. RESULTS: BRCAPANCPRO outperformed the prior BRCAPRO and PANCPRO models and yielded good discrimination for differentiating BRCA1 and BRCA2 carriers from non-carriers (AUCs 0.79, 95% CI: 0.73-0.84 and 0.70, 95% CI: 0.60-0.80) in families seen in high-risk clinics and pancreatic cancer family registries, respectively. In addition, BRCAPANCPRO was reasonably well calibrated for predicting future risk of pancreatic cancer (observed-to-expected (O/E) ratio = 0.81 [0.69, 0.94]). DISCUSSION: The BRCAPANCPRO model provides improved risk assessment over our previous risk models, particularly for pedigrees with a co-occurrence of pancreatic cancer and breast and/or ovarian cancer.

RESUMO

BACKGROUND: Patients participating in phase I trials represent a population with advanced cancer and symptoms, with quality-of-life implications arising from both disease and treatment. Transitions to end-of-life care for these patients have received little attention. Good empirical data are needed to better understand the role of advance care planning and palliative care during phase I trial transitions. We investigated how physician-patient communication at the time of disease progression, patient characteristics, and patterns of care were associated with end-of-life care. METHODS: We conducted a retrospective chart review of all patients with solid tumors enrolled in phase I trials at a comprehensive cancer center from January 2015 to December 2017. We captured physician-patient communication during disease progression. Among patients who died, we assessed palliative care referral, advance care planning, place of death, healthcare use in the final month of life, hospice enrollment, and hospice length of stay (LOS). Factors independently associated with a short hospice LOS (defined as ≤3 days) were estimated from a multivariable model building approach. RESULTS: Among 207 participants enrolled in phase I intervention studies at Johns Hopkins Hospital, the median age was 61 years (range, 31-91 years), 48% were women, 21% were members of racial minority groups, and 41.5% were referred from an outside institution. At the time of disease progression, 53% had goals of care documented, 47% were previously referred to palliative care, and 41% discussed hospice with their oncologist. A total of 82% of decedents died within 1 year of study enrollment, and 85% enrolled in hospice. Among the 147 participants who enrolled in hospice, 22 (15%) had a short LOS (≤3 days). Factors independently associated with an increased risk of short hospice LOS in the multivariable model included age >65 years (odds ratio [OR], 1.12; 95% CI, 1.01-1.24; P=.04), whereas remaining at the same institution (OR, 0.72; 95% CI, 0.65-0.80; P<.001) and referral to palliative care before progression (OR, 0.83; 95% CI, 0.75-0.92; P<.001) were associated with a decreased risk of short hospice LOS. CONCLUSIONS: Reported data support the benefit of palliative care for patients in phase I trials and the risks associated with healthcare transitions for all patients, particularly older adults, regardless of care received. Leaving a clinical trial is a time when clear communication is paramount. Phase I studies will continue to be vital in advancing cancer treatment. It is equally important to advance the support provided to patients who transition off these trials.

RESUMO

BACKGROUND: The prevalence of survivors of oropharyngeal cancer (OPC) is increasing due to improved survival for individuals with human papillomavirus (HPV)-related disease. Although elderly survivors of OPC are known to have a high burden of comorbidities, to the authors' knowledge it is unknown how this compares with a similar cohort without a history of cancer. METHODS: The current retrospective, cross-sectional study included individuals with a first incident primary diagnosis of OPC from 2004 through 2011 from the Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked databases and matched controls. The baseline prevalence and subsequent incidence of comorbid conditions were identified. The association between comorbidity and overall survival was evaluated. RESULTS: A total of 2497 eligible patients with OPC were matched to 4994 noncancer controls. Baseline comorbidity was higher in cases (Charlson Comorbidity Index >0 for 48.5% of cases vs 35.8% of controls). At 5 years, cases were more likely than controls to develop comorbidities. Survivors of OPC were at high risk (≥20% cumulative prevalence by 5 years) of developing several comorbidities, including cardiovascular diseases, cerebrovascular disease, chronic obstructive pulmonary disease, and tobacco abuse, and were at moderately high risk (10%-19% cumulative prevalence) of developing other conditions including carotid artery occlusive stroke, alcohol abuse, depression, and anxiety. In both cases and controls, the presence of the majority of comorbidities either at the time of diagnosis or during the follow-up period was associated with worse survival. CONCLUSIONS: Patients with OPC have a higher comorbidity burden compared with matched controls, both at baseline and during survivorship, the majority of which are associated with decreased survival. Oncologic surveillance of survivors of OPC should include screening for highly prevalent conditions.

RESUMO

PURPOSE: A delay in breast cancer treatment is associated with inferior survival outcomes; however, no clear guidelines exist defining the appropriate time frame from diagnosis to definitive treatment of breast cancer. A multidisciplinary approach for breast cancer treatment can minimize the time from diagnosis to first treatment. We hypothesized single-day multidisciplinary clinic (MDC) may accelerate the time to first treatment on complex breast cancer cases at our institution. METHODS: We identified patients who were treated at Johns Hopkins for stage II or III breast cancer, who were at least 18 years of age, and were seen in a new single-day MDC with coordination between two or three specialties or by specialists from varying disciplines on different days (IDC). Patients who initiated treatment between May 2015 (initiation of MDC clinic) and December 2017 were included in our study. RESULTS: A total of 296 patient records were reviewed independently. The mean (SD) patient age was 55 (13) years. The median time to first neoadjuvant chemotherapy (NACT) was significantly reduced for patients seen in the MDC (12.7 days), compared to those seen at the IDC (24.4 days, logrank p < 0.001). The median time to definitive surgery was similar between groups (31 and 32 days for the MDC and IDC cohorts, respectively). CONCLUSIONS: A single-day MDC visit is associated with a reduced time from diagnosis to NACT. Further studies are needed to determine if a shorter interval can improve the management and the outcome of complex breast cancer cases.

RESUMO

PURPOSE: Survivorship care plans (SCPs) provide key information about cancer treatment history and follow-up recommendations. We describe the completeness of breast cancer SCPs and evaluate guideline concordance of follow-up recommendations. METHODS: We analyzed 149 breast cancer SCPs from two sites, abstracting demographics, cancer/treatment details, surveillance plans, and health promotion advice. SCP recommendations and provided information were compared to American Cancer Society/American Society of Clinical Oncology and National Comprehensive Cancer Network guidelines. RESULTS: SCP information provided in > 90% of the plans included patient age; relevant providers; cancer stage; treatment details; and physical exam, mammogram, and health promotion recommendations. SCP components completed less frequently included post-treatment symptoms/side effects (67%). All SCPs at the community site were uniform but had the potential for oversurveillance if visits occurred every 3 months in years 1-2 or every 6 months in years 3-5 with multiple cancer providers. The academic site recommended three predominant patterns of follow-up: (1) primary care provider every 6-12 months; (2) cancer team every 3-6 months (year 1), every 6-12 months (years 4-5); and (3) alternating oncology providers every 3-6 months (years 1-2) then every 6 months. Compared to guidelines, these patterns recommend under- and oversurveillance at various times. Mammography recommendations showed guideline concordance (annual) for 84%, oversurveillance for 10%, and were incomplete for 6%. SCPs of only 12/79 (15%) women on aromatase inhibitors recommended guideline-concordant bone density testing. CONCLUSIONS: SCP content is more complete for demographic and treatment summary information but has follow-up recommendation gaps. Efforts to improve follow-up recommendations are needed.

RESUMO

Inflammatory cytokines released by activated lymphocytes and innate cells in the context of cellular therapy can cause fever, vasodilatation, and end-organ damage, collectively known as cytokine release syndrome (CRS). CRS can occur after allogeneic blood or marrow transplantation, but is especially prevalent after HLA-haploidentical (haplo) peripheral blood transplantation (PBT). We reviewed charts of all patients who underwent haplo-PBT between October 1, 2013, and September 1, 2017 and graded CRS in these patients. A total of 146 consecutive patients who underwent related haplo-PBT were analyzed. CRS occurred in 130 patients (89%), with most cases of mild severity (grade 0 to 2). Severe CRS (grade 3 to 5) occurred in 25 patients (17%). In this group with severe CRS, 13 patients had encephalopathy, 12 required hemodialysis, and 11 were intubated. Death from the immediate complications of CRS occurred in 6 patients (24% of the severe CRS group and 4% of the entire haplo-PBT cohort). The cumulative probability of nonrelapse mortality (NRM) was 38% at 6 months for the patients with severe CRS and 8% (121 of 146) in patients without severe CRS. In conclusion, CRS occurs in nearly 90% of haplo-PBTs. Older haplo-PBT recipients (odds ratio [OR], 2.4; 95% confidence interval [CI], .83 to 6.75; P = .11) and those with a history of radiation therapy (OR, 3.85; 95% CI, 1.32 to 11.24; P = .01) are at increased risk of developing severe CRS. Although most recipients of haplo-PBT develop CRS, <20% experience severe complications. The development of severe CRS is associated with a significantly increased risk of NRM.

RESUMO

BACKGROUND: The increasing incidence of human papillomavirus (HPV)-related head and neck cancer (HNC) has led to the increasing prevalence of survivors, yet to the best of the authors' knowledge the prevalence of comorbidities during the survivorship period and their effects on survival are relatively unknown. METHODS: In this retrospective cross-sectional study, individuals with a first incident primary diagnosis of HNC from 2004 through 2011 from the Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked databases were included in the analysis and classified as patients with HPV-related or HPV-unrelated HNC. The presence of 30 comorbid conditions of interest was identified. Associations between comorbidity and treatment group as well as overall survival were evaluated. RESULTS: The study population consisted of 8025 patients with HPV-unrelated HNC and 2499 patients with HPV-related HNC. Hypertension, congestive heart failure, cerebrovascular disease, and chronic obstructive pulmonary disease all were found to be highly prevalent at the time of the cancer diagnosis and increased over time for both groups. These comorbidities were found at significantly lower rates in the HPV-related HNC population, yet were associated with an increased risk of death in both groups. The probabilities of developing cancer-related comorbidities such as pneumonia, dysphagia, weight loss, malnutrition, and dental issues rose significantly in both groups after treatment but were more likely in patients with HPV-related HNC. In both groups of patients, the presence of each comorbidity either at the time of diagnosis or during survivorship was associated with a significantly increased risk of death. CONCLUSIONS: There is a large burden of comorbidities in both patients with HPV-related and HPV-unrelated HNC, both of which are associated with decreased survival. Oncologic surveillance should not be limited to the evaluation of disease status, but also should include screening for the highly prevalent conditions associated with the risk of death.

RESUMO

BACKGROUND: Long-term treatment with supplemental oxygen has unknown efficacy in patients with stable chronic obstructive pulmonary disease (COPD) and resting or exercise-induced moderate desaturation. METHODS: We originally designed the trial to test whether long-term treatment with supplemental oxygen would result in a longer time to death than no use of supplemental oxygen among patients who had stable COPD with moderate resting desaturation (oxyhemoglobin saturation as measured by pulse oximetry [Spo2], 89 to 93%). After 7 months and the randomization of 34 patients, the trial was redesigned to also include patients who had stable COPD with moderate exercise-induced desaturation (during the 6-minute walk test, Spo2 ≥80% for ≥5 minutes and <90% for ≥10 seconds) and to incorporate the time to the first hospitalization for any cause into the new composite primary outcome. Patients were randomly assigned, in a 1:1 ratio, to receive long-term supplemental oxygen (supplemental-oxygen group) or no long-term supplemental oxygen (no-supplemental-oxygen group). In the supplemental-oxygen group, patients with resting desaturation were prescribed 24-hour oxygen, and those with desaturation only during exercise were prescribed oxygen during exercise and sleep. The trial-group assignment was not masked. RESULTS: A total of 738 patients at 42 centers were followed for 1 to 6 years. In a time-to-event analysis, we found no significant difference between the supplemental-oxygen group and the no-supplemental-oxygen group in the time to death or first hospitalization (hazard ratio, 0.94; 95% confidence interval [CI], 0.79 to 1.12; P=0.52), nor in the rates of all hospitalizations (rate ratio, 1.01; 95% CI, 0.91 to 1.13), COPD exacerbations (rate ratio, 1.08; 95% CI, 0.98 to 1.19), and COPD-related hospitalizations (rate ratio, 0.99; 95% CI, 0.83 to 1.17). We found no consistent between-group differences in measures of quality of life, lung function, and the distance walked in 6 minutes. CONCLUSIONS: In patients with stable COPD and resting or exercise-induced moderate desaturation, the prescription of long-term supplemental oxygen did not result in a longer time to death or first hospitalization than no long-term supplemental oxygen, nor did it provide sustained benefit with regard to any of the other measured outcomes.
