Circulating microRNAs can predict chemotherapy-induced toxicities in patients being treated for primary breast cancer.

PURPOSE: Prescribing NAC for breast cancer is a pragmatic treatment strategy for several reasons; however, certain patients suffer chemotherapy-induced toxicities. Unfortunately, identifying patients at risk of toxicity often proves challenging. MiRNAs are small non-coding RNA molecules which modulate genetic expression. The aim of this study was to determine whether circulating miRNAs are sensitive biomarkers that can identify the patients likely to suffer treatment-related toxicities to neoadjuvant chemotherapy (NAC) for primary breast cancer. METHODS: This secondary exploratory from the prospective, multicentre translational research trial (CTRIAL ICORG10/11-NCT01722851) recruited 101 patients treated with NAC for breast cancer, from eight treatment sites across Ireland. A predetermined five miRNAs panel was quantified using RQ-PCR from patient bloods at diagnosis. MiRNA expression was correlated with chemotherapy-induced toxicities. Regression analyses was performed using SPSS v26.0. RESULTS: One hundred and one patients with median age of 55 years were recruited (range: 25-76). The mean tumour size was 36 mm and 60.4% had nodal involvement (n = 61) Overall, 33.7% of patients developed peripheral neuropathies (n = 34), 28.7% developed neutropenia (n = 29), and 5.9% developed anaemia (n = 6). Reduced miR-195 predicted patients likely to develop neutropenia (P = 0.048), while increased miR-10b predicted those likely to develop anaemia (P = 0.049). Increased miR-145 predicted those experiencing nausea and vomiting (P = 0.019), while decreased miR-21 predicted the development of mucositis (P = 0.008). CONCLUSION: This is the first study which illustrates the value of measuring circulatory miRNA to predict patient-specific toxicities to NAC. These results support the ideology that circulatory miRNAs are biomarkers with utility in predicting chemotherapy toxicity as well as treatment response.

Long-term outcomes in Hodgkin lymphoma survivors. Temporary trends and comparison with general population.

The high cure rates of Hodgkin lymphoma (HL) make this oncological disease among those with the greatest number of long-term survivors. This single-institution study including 383 HL patients with up to 45 years of follow-up, analyses the morbidity and mortality of this population after treatments in comparison with the overall Spanish population, and investigates whether it has changed over time stratifying by periods of time, as a consequence of therapeutic optimization. The median age was 34.8 years (range 15-87) with median overall survival of 30 years, significantly higher in women (HR 0.58, 95% CI 0.42-0.79) (p = 0.0002). 185 late-stage diseases were noted (35% patients), cardiovascular disease (CVD) being the most frequent (23.2%). 30% of patients developed at least one second malignant neoplasm (SMN) to give a total of 174 SMNs. 20.9% of the patients died from HL and 67.0% died from non-HL causes (32.2% from SMN, 17% from CVD). The overall standardized mortality ratio (SMR) was 3.57 (95% CI: 3.0-4.2), with striking values of 7.73 (95% CI: 5.02-8.69) and of 14.75 (95% CI: 11.38-19.12) for women and patients <30 years at diagnosis, respectively. Excluding HL as the cause of death, the SMRs of those diagnosed before 2000 and from 2000 were proved to be similar (3.88 vs 2.73), maintaining in this last period an unacceptable excess of mortality due to secondary toxicity in patients cured of HL. Our study confirm that HL treatment substantially reduces the life expectancy of patients cured of HL. In recent periods, despite therapeutic optimization, deaths from toxicity continue to occur, mainly from CVD and SMN. Risk-factor monitoring should be intensified, prevention programs developed, and therapeutic optimization of LH investigated, especially in two vulnerable groups: those aged <30 years at diagnosis, and women.

Feasibility and Effectiveness of Self-Management Education and Coaching on Patient Activation for Managing Cancer Treatment Toxicities.

BACKGROUND: Poorly managed cancer treatment toxicities negatively impact quality of life, but little research has examined patient activation in self-management (SM) early in cancer treatment. METHODS: We undertook a pilot randomized trial to evaluate the feasibility, acceptability, and preliminary effectiveness of the SMARTCare (Self-Management and Activation to Reduce Treatment Toxicities) intervention. This intervention included an online SM education program (I-Can Manage) plus 5 sessions of telephone cancer coaching in patients initiating systemic therapy for lymphoma or colorectal or lung cancer at 3 centers in Ontario, Canada, relative to a usual care control group. Patient-reported outcomes included patient activation (Patient Activation Measure [PAM]), symptom or emotional distress, self-efficacy, and quality of life. Descriptive statistics and Wilcoxon rank-sum tests were used to examine changes over time (baseline and at 2, 4, and 6 months) within and between groups. We used general estimating equations to compare outcomes between groups over time. The intervention group completed an acceptability survey and qualitative interviews. RESULTS: Of 90 patients approached, 62 (68.9%) were enrolled. Mean age of the sample was 60.5 years. Most patients were married (77.1%), were university educated (71%), had colorectal cancer (41.9%) or lymphoma (42.0%), and had stage III or IV disease (75.8%). Attrition was higher in the intervention group than among control subjects (36.7% vs 25%, respectively). Adherence to I-Can Manage was low; 30% of intervention patients completed all 5 coaching calls, but 87% completed ≥1. Both the continuous PAM total score (P<.001) and categorical PAM levels (3/4 vs 1/2) (P=.002) were significantly improved in the intervention group. CONCLUSIONS: SM education and coaching early during cancer treatment may improve patient activation, but a larger trial is needed. CLINICALTRIALS: gov Identifier: NCT03849950.

Reliability of patient-reported toxicities during adjuvant chemotherapy.

BACKGROUND: Patient-reported outcomes (PROs) are validated tools to assess the impact of efficacy and toxicities of cancer treatments on patients' health status. Because of the demonstrated little reliability of humans in reporting memories of painful experiences, this work explores the reliability of cancer patients in reporting chemotherapy-related toxicities. AIM: This study aims to evaluate the concordance between toxicities experienced by the patients during chemotherapy and toxicities reported to the doctor at the end of the cycles. METHODS: Questionnaires concerning chemotherapy-related toxicities were administered on days 2, 5, 8, 11, 14, and 17 of each chemo cycle and at the end of the same cycle to patients undergoing adjuvant chemotherapy. The co-primary end-points were Lins's concordance correlation coefficient (CCC) and mean difference between real-time and retrospective toxicity assessments. RESULTS: In total, 7182 toxicity assessments were collected from 1096 questionnaires. Concordance was observed between the retrospective evaluations and the toxicity assessments at early (day 2), peak (maximum toxicity), late (day 14 or 17), and mean real-time evaluations for each chemotherapy cycle (CCC for mean ranging from 0.52 to 0.77). No systematic discrepancy was found between real-time and retrospective evaluations, except for peak, which was systematically underestimated retrospectively. CONCLUSIONS: Toxicities reported by the patients to the doctor at the end of each chemotherapy cycle reflect what they actually experienced without any substantial distortion. This result is very relevant both for the clinical implications in daily patients' management and in the light of the current growing impact on digital monitoring of PROs.

A Geriatric Assessment Intervention to Reduce Treatment Toxicity Among Older Adults With Advanced Lung Cancer: A Subgroup Analysis From a Cluster Randomized Controlled Trial.

Introduction: More older adults die from lung cancer worldwide than breast, prostate, and colorectal cancers combined. Current lung cancer treatments may prolong life, but can also cause considerable treatment-related toxicity. Objective: This study is a secondary analysis of a cluster-randomized clinical trial which evaluated whether providing a geriatric assessment (GA) summary and GA-guided management recommendations can improve grade 3-5 toxicity among older adults with advanced lung cancer. Methods: We analyzed participants aged ≥70 years(y) with stage III & IV (advanced) lung cancer and ≥1 GA domain impairment starting a new cancer treatment with high-risk of toxicity within the National Cancer Institute's Community Oncology Research Program. Community practices were randomized to the intervention arm (oncologists received GA summary & recommendations) versus usual care (UC: no summary or recommendations given). The primary outcome was grade 3-5 toxicity through 3 months post-treatment initiation. Secondary outcomes included 6-month (mo) and 1-year overall survival (OS), treatment modifications, and unplanned hospitalizations. Outcomes were analyzed using generalized linear mixed and Cox proportional hazards models with practice site as a random effect. Trial Registration: NCT02054741. Results & Conclusion: Among 180 participants with advanced lung cancer, the mean age was 76.3y (SD 5.1), 39.4% were female and 82.2% had stage IV disease. The proportion of patients who experienced grade 3-5 toxicity was significantly lower in the intervention arm vs UC (53.1% vs 71.6%, P=0.01). More participants in the intervention arm received lower intensity treatment at cycle 1 (56.3% vs 35.3%; P<0.01). Even with a cycle 1 dose reduction, OS at 6mo and 1 year was not significantly different (adjusted hazard ratio [HR] intervention vs. UC: 6mo HR=0.90, 95% CI: 0.52-1.57, P=0.72; 1 year HR=0.89, 95% CI: 0.58-1.36, P=0.57). Frequent toxicity checks, providing education and counseling materials, and initiating direct communication with the patient's primary care physician were among the most common GA-guided management recommendations. Providing a GA summary and management recommendations can significantly improve tolerability of cancer treatment among older adults with advanced lung cancer.

Rate of Curative Surgery in Real-world Patients with Unresectable Metastatic Colorectal Cancer Treated with FOLFOXIRI ± Bevacizumab: A Western Canadian Province Experience.

BACKGROUND: Recent evidence from randomized trials suggests that FOLFOXIRI (fluorouracil, oxaliplatin, and irinotecan) ± bevacizumab is associated with higher response rates, with the potential for conversion of unresectable to resectable disease in metastatic colorectal cancer (mCRC). However, limited evidence is available on the efficacy and safety of this regimen in real-world patients with mCRC. The current study aims to evaluate the conversion rate and safety of FOLFOXIRI ± bevacizumab in real-world patients with unresectable mCRC. METHODS: In this retrospective multicenter population-based cohort study, patients who were diagnosed with unresectable mCRC between January 2015 and December 2018 in Saskatchewan and received FOLFOXIRI ± bevacizumab were assessed. Kaplan-Meier survival methods and the log-rank test were performed. RESULTS: A total of 28 eligible patients with a median age of 51 years (interquartile range 39-60) and a male:female ratio of 11:17 were identified; 39% had rectal cancer, 46% had extrahepatic disease, and 46% had bilobar liver metastases. Overall, 63% of the patients had a positive response to FOLFOXIRI ± bevacizumab and 53% underwent metastasectomy. Of all patients 60% had grade 3/4 toxicity and 32% required hospital admission. No treatment-related mortality was noted. After 4 years, 50% of the patients were alive. Median progression-free survival of patients who underwent surgery was 18 months (95% CI 11.3-24.7) versus 11 months (4-18.1) without surgery (p = 0.28). Median overall survival of patients with surgery was 33 months (17.5-48.5) versus 16 months (8.3-23.7) without surgery (p = 0.03). CONCLUSION: The current study suggests that FOLFOXIRI ± bevacizumab therapy in real-world patients with mCRC is associated with a high rate of conversion from unresectable to resectable metastatic disease. Patients with metastasectomy had better survival.

Novel Therapies in Oncology: An Individualized Approach.

For decades, oncology treatments revolved around chemotherapeutic regimens that have been relatively nonspecific in their approach to cancer cell death. With advancements in genomics and personalized medicine, however, knowledge of the immune system has dramatically increased and methods for treating cancers have become much more individualized. With this increase in knowledge, vast arrays of novel therapies have entered the oncology realm. Nurses are expected to administer these therapies and ultimately manage the resulting toxicities and side effects. Such effects sometimes lead to severe illness, which may require intensive care unit admission. This article reviews novel therapies in oncology and nursing considerations pertaining to these treatment approaches as they relate to solid tumors.

Long-term outcomes of moderately hypofractionated radiotherapy (67.5 Gy in 25 fractions) for prostate cancer confined to the pelvis: a single center retrospective analysis.

BACKGROUND: There is an increasing application of moderately hypofractionated radiotherapy for prostate cancer. We presented our outcomes and treatment-related toxicities with moderately hypofractionated (67.5 Gy in 25 fractions) radiotherapy for a group of advanced prostate cancer patients from China. METHODS: From November 2006 to December 2018, 246 consecutive patients with prostate cancer confined to the pelvis were treated with moderately hypofractionated radiotherapy (67.5 Gy in 25 fractions). 97.6% of the patients received a different duration of androgen deprivation therapy. Failure-free survival (FFS), prostate cancer-specific survival (PCSS), overall survival (OS), and cumulative grade ≥ 2 late toxicity were evaluated using the Kaplan-Meier actuarial method. Prognostic factors for FFS, PCSS, and OS were analyzed. RESULTS: The median follow-up time was 74 months (range: 6-150 months). For all patients, the 5- and 10-year FFS rates were 80.0% (95% CI: 74.7-85.7%) and 63.5% (95% CI 55.4-72.8%). The failure rates for the intermediate, high-risk, locally advanced, and N1 groups were 6.1%, 13.0%, 18.4%, and 35.7%, respectively (P = 0.003). Overall, 5- and 10-year PCSS rates were 95.7% (95% CI 93.0-98.5%) and 88.2% (95% CI 82.8-93.8%). Prostate cancer-specific mortality rates for the high-risk, locally advanced, and N1 groups were 4.0%, 8.2%, and 23.8%, respectively (P < 0.001). Overall, 5- and 10-year actuarial OS rates were 92.4% (95% CI 88.8-96.1%) and 72.7% (95% CI 64.8-81.5%). High level prostate-specific antigen and positive N stage were significantly associated with worse FFS (P < 0.05). Advanced T stage and positive N stage emerged as worse predictors of PCSS (P < 0.05). Advanced age, T stage, and positive N stage were the only factors that were significantly associated with worse OS (P < 0.05). The 5-year cumulative incidence rate of grade ≥ 2 late GU and GI toxicity was 17.8% (95% CI 12.5-22.7%) and 23.4% (95% CI 17.7-28.7%), respectively. CONCLUSIONS: Moderately hypofractionated radiotherapy (67.5 Gy in 25 fractions) for this predominantly high-risk, locally advanced, or N1 in Chinese patients demonstrates encouraging long-term outcomes and acceptable toxicity. This fractionation schedule deserves further evaluation in similar populations.

Adjuvant Chemotherapy Use in Patients With Locally Advanced Rectal Cancer: A Single-Institution Experience.

BACKGROUND: National Comprehensive Cancer Network guidelines for the treatment of locally advanced rectal cancer advocate neoadjuvant chemoradiotherapy followed by total mesorectal excision and adjuvant chemotherapy (AC). The aim of this retrospective study was to determine our local patterns of AC use and to examine factors that influenced initiation and completion of AC among patients with stage II/III rectal cancer. PATIENTS AND METHODS: The study population consisted of stage II/III rectal cancer patients who were treated at the University of Rochester from 2011 to 2014. Chart reviews were conducted to determine rates of AC initiation and completion. The documented reasons for failure to initiate or complete AC were examined. A multivariate analysis was also completed to evaluate factors that may have influenced the initiation and use of AC. RESULTS: Eighty-one patients were included in the analysis. Median age was 62 years, and 53 (65.4%) were male. Median time from surgery to initiation of AC in those who received AC was 8.0 weeks. Forty-seven patients (58.0%) completed their prescribed AC course. Twenty-four patients (29.6%) did not start AC and 9 patients (11.1%) were unable to complete their course of AC. Primary reasons for not undergoing AC were patient preference (37.5%) and prolonged surgical recovery (33.3%). Primary reasons for not completing AC were treatment toxicities (55.5%) and patient preference (22.2%). Multivariate analysis identified a positive association between clinical stage III disease at diagnosis and initiation of AC. There was no independent association between pathologic response to neoadjuvant therapy at time of surgery and receipt of AC. CONCLUSION: A large proportion of patients at a single academic center did not start or complete their prescribed postoperative AC for locally advanced rectal cancer. Ongoing studies are investigating a total neoadjuvant approach, which may result in better chemotherapy adherence and further improve the pathologic downstaging rate.

Head and Neck Dystonia Following Chimeric-Antigen Receptor T-Cell Immunotherapy: A Case Report.

Chimeric antigen receptor T-cell therapy (CAR-T) is a novel immunotherapy used for the treatment of refractory B-cell leukemias and lymphoma. As clinical trials continue to expand, multiple treatment toxicities have been documented. Treatment-associated toxicities are typically systemic, however, focal manifestations have been described. We present a unique case of a 55-year-old female who developed oropharyngeal and laryngeal dystonia following CAR-T therapy. This case points to a possible association between CAR-T therapy and focal head and neck dystonia. Laryngoscope, 2020.

Consensus-Building efforts to identify best tools for screening and assessment for supportive services in oncology.

Purpose: To build consensus around an optimal patient-reported outcome measure of cancer symptoms and patient needs to facilitate patient-provider communication and trigger referrals to supportive services.Methods and materials: The Grid-Enabled Measures platform was used to crowdsource and facilitate collaboration to achieve consensus. Respondents were invited to nominate and independently rate the usefulness of measures that: (1) have been actively used at a healthcare institution, (2) have a multiple choice or yes/no type format, (3) are applicable to adults with cancer, (4) are patient-reported, and 5) have psychometric data if possible. Discussion boards within the GEM workspace allowed respondents to identify barriers to implementing patient assessment and referral systems.Results: 166 individuals from various disciplines from 25 organizations participated. Six instruments were nominated, and 553 rating surveys were submitted. The three most highly-rated overall instruments were the Distress Thermometer, the James Supportive Case Screening, and the Functional Assessment of Cancer Therapy-General. Participants noted that wide-scale implementation of this process requires both identifying problems and providing clinicians with algorithms to facilitate appropriate referrals.Conclusions: Consensus reported three most highly-related measures as optimal for comprehensive screening and identification for referral by assessing multiple domains of functioning and quality of life.Implications for RehabilitationGaining consensus on the best patient reported outcome measures is an important step towards improving access to cancer rehabilitation services.A consensus agreed on several measures to use for cancer rehabilitation screening. Functional Assessment of Cancer Therapy-General, National Comprehensive Cancer. Network Distress Thermometer and the James Instrument.The selected measures do not put undue burden on clinicians and patients.

National treatment trends in human papillomavirus-positive oropharyngeal squamous cell carcinoma.

BACKGROUND: Human papillomavirus (HPV)-mediated oropharyngeal cancer (OPC) is associated with dramatically improved survival in comparison with HPV-negative OPC and can be successfully treated with surgical and nonsurgical approaches. National treatment trends for OPC were investigated with the National Cancer Data Base (NCDB). METHODS: The NCDB was reviewed for primary HPV-mediated OPC in 2010-2014. Multivariable regression was used to identify predictors of both nonsurgical therapy and receipt of adjuvant chemoradiation (CRT). RESULTS: There were 13,363 patients identified with a median age at diagnosis of 58 years. The incidence of triple-modality treatment (surgery with adjuvant chemotherapy) decreased from 23.7% in 2010 to 16.9% in 2014 (R2  = 0.96), whereas the incidence of nonsurgical treatment increased from 63.9% to 68.7% (R2  = 0.89). Hospitals in the top treatment volume quartile (quartile 1 [Q1]; n = 29) had a lower rate of positive margins (16.3%) than bottom-quartile centers (n = 741; rate of positive margins, 36.4%; P < .001); Q1 hospitals used surgical therapy significantly more. Independent predictors of nonsurgical therapy included older age, advanced disease, lower hospital volume, and living closer to the hospital or outside the Pacific United States. In surgically treated patients, younger age, lower hospital volume, nodal disease, positive surgical margins, and extranodal extension (ENE) also predicted more adjuvant CRT use. CONCLUSIONS: The use of upfront surgical treatment decreased from 2010 to 2014. Hospital volume shows a strong, inverse correlation with the rate of positive surgical margins. The upfront treatment strategy is predicted not only by staging but also by patient-, geographic-, and hospital-specific factors. Lower hospital volume remains independently associated with increased triple-modality therapy after adjustments for positive margins, ENE, and pathologic staging.

Tumor safety and side effects of photobiomodulation therapy used for prevention and management of cancer treatment toxicities. A systematic review.

Photobiomodulation therapy (PBMT), also known as low-level laser therapy (LLLT), has been increasingly used for the treatment of toxicities related to cancer treatment. One of the challenges for the universal acceptance of PBMT use in cancer patients is whether or not there is a potential for the light to stimulate the growth of residual malignant cells that evaded oncologic treatment, increasing the risk for tumor recurrences and development of a second primary tumor. Current science suggests promising effects of PBMT in the prevention and treatment of breast cancer-related lymphedema and oral mucositis, among other cancer treatment toxicities. Nevertheless, this seems to be the first systematic review to analyze the safety of the use of PBMT for the management of cancer-related toxicities. Scopus, MEDLINE/PubMed, and Embase were searched electronically. A total of 27 articles met the search criteria. Selected studies included the use of PBMT for prevention and treatment of oral mucositis, lymphedema, radiodermatitis, and peripheral neuropathy. Most studies showed that no side effects were observed with the use of PBMT. The results of this systematic review, based on current literature, suggest that the use of PBMT in the prevention and management of cancer treatment toxicities does not lead to the development of tumor safety issues.

Symptom Trajectories in Children Receiving Treatment for Leukemia: A Latent Class Growth Analysis With Multitrajectory Modeling.

CONTEXT: Cancer treatment symptoms play a major role in determining the health of children with cancer. Symptom toxicity often results in complications, treatment delays, and therapy dose reductions that can compromise leukemia therapy and jeopardize chances for long-term survival. Critical to understanding symptom experiences during treatment is the need for exploration of "why" inter-individual symptom differences occur; this will determine who may be most susceptible to treatment toxicities. OBJECTIVES: This study examined specific symptom trajectories during the first 18 months of childhood leukemia treatment. Symptom measures included fatigue, sleep disturbances, pain, nausea, and depression. METHODS: Symptom trajectories of 236 children with leukemia three to 18 years old were explored prospectively over four periods: initiation of post-induction therapy, four and eight post-induction therapy, and the last time point was at the beginning of maintenance/continuation therapy. Latent class growth analysis was used to classify patients into distinctive groups with similar symptom trajectories based on patients' response patterns on the symptom measures over time. RESULTS: Three latent classes of symptom trajectories were identified and classified into mild, moderate, and severe symptom trajectories. The only demographic characteristic with a significant relationship to membership in the latent class symptom trajectories was race/ethnicity. All other demographic characteristics including leukemia risk levels showed no significant relationships. CONCLUSION: This study is unique in that groups of patients with similar symptoms were identified rather than groups of symptoms. Further research using latent class growth analysis is needed.

Supportive care during treatment for breast cancer: resource allocations in low- and middle-income countries. A Breast Health Global Initiative 2013 consensus statement.

Breast cancer patients may have unmet supportive care needs during treatment, including symptom management of treatment-related toxicities, and educational, psychosocial, and spiritual needs. Delivery of supportive care is often a low priority in low- and middle-income settings, and is also dependent on resources available. This consensus statement describes twelve key recommendations for supportive care during treatment in low- and middle-income countries, identified by an expert international panel as part of the 5th Breast Health Global Initiative (BHGI) Global Summit for Supportive Care, which was held in October 2012, in Vienna, Austria. Panel recommendations are presented in a 4-tier resource-stratified table to illustrate how health systems can provide supportive care services during treatment to breast cancer patients, starting at a basic level of resource allocation and incrementally adding program resources as they become available. These recommendations include: health professional and patient and family education; management of treatment related toxicities, management of treatment-related symptoms of fatigue, insomnia and non-specific pain, and management of psychosocial and spiritual issues related to breast cancer treatment. Establishing supportive care during breast cancer treatment will help ensure that breast cancer patients receive comprehensive care that can help 1) improve adherence to treatment recommendations, 2) manage treatment-related toxicities and other treatment related symptoms, and 3) address the psychosocial and spiritual aspects of breast cancer and breast cancer treatments.
