Cancer is a disease of aging and, as the world's population ages, the number of older persons with cancer is increasing and will make up a growing share of the oncology population in virtually every ...country. Despite this, older patients remain vastly underrepresented in research that sets the standards for cancer treatments. Consequently, most of what we know about cancer therapeutics is based on clinical trials conducted in younger, healthier patients, and effective strategies to improve clinical trial participation of older adults with cancer remain sparse. For this systematic review, the authors evaluated published studies regarding barriers to participation and interventions to improve participation of older adults in cancer trials. The quality of the available evidence was low and, despite a literature describing multifaceted barriers, only one intervention study aimed to increase enrollment of older adults in trials. The findings starkly amplify the paucity of evidence‐based, effective strategies to improve participation of this underrepresented population in cancer trials. Within these limitations, the authors provide their opinion on how the current cancer research infrastructure must be modified to accommodate the needs of older patients. Several underused solutions are offered to expand clinical trials to include older adults with cancer. However, as currently constructed, these recommendations alone will not solve the evidence gap in geriatric oncology, and efforts are needed to meet older and frail adults where they are by expanding clinical trials designed specifically for this population and leveraging real‐world data.
Based on a systematic literature review, the screening tools task force of SIOG states that screening tools do not replace geriatric assessment in older cancer patients. However, in a busy clinical ...practice the use of such a tool is recommended to identify those patients in need of further evaluation and multidisciplinary approach. Further research remains necessary.
Screening tools are proposed to identify those older cancer patients in need of geriatric assessment (GA) and multidisciplinary approach. We aimed to update the International Society of Geriatric Oncology (SIOG) 2005 recommendations on the use of screening tools.
SIOG composed a task group to review, interpret and discuss evidence on the use of screening tools in older cancer patients. A systematic review was carried out and discussed by an expert panel, leading to a consensus statement on their use.
Forty-four studies reporting on the use of 17 different screening tools in older cancer patients were identified. The tools most studied in older cancer patients are G8, Flemish version of the Triage Risk Screening Tool (fTRST) and Vulnerable Elders Survey-13 (VES-13). Across all studies, the highest sensitivity was observed for: G8, fTRST, Oncogeriatric screen, Study of Osteoporotic Fractures, Eastern Cooperative Oncology Group-Performance Status, Senior Adult Oncology Program (SAOP) 2 screening and Gerhematolim. In 11 direct comparisons for detecting problems on a full GA, the G8 was more or equally sensitive than other instruments in all six comparisons, whereas results were mixed for the VES-13 in seven comparisons. In addition, different tools have demonstrated associations with outcome measures, including G8 and VES-13.
Screening tools do not replace GA but are recommended in a busy practice in order to identify those patients in need of full GA. If abnormal, screening should be followed by GA and guided multidisciplinary interventions. Several tools are available with different performance for various parameters (including sensitivity for addressing the need for further GA). Further research should focus on the ability of screening tools to build clinical pathways and to predict different outcome parameters.
Behavioral pain management interventions are efficacious for reducing pain in patients with cancer. However, optimal dosing of behavioral pain interventions for pain reduction is unknown, and this ...hinders routine clinical use. A Sequential Multiple Assignment Randomized Trial (SMART) was used to evaluate whether varying doses of Pain Coping Skills Training (PCST) and response-based dose adaptation can improve pain management in women with breast cancer. Participants (N = 327) had stage I-IIIC breast cancer and a worst pain score of > 5/10. Pain severity (a priori primary outcome) was assessed before initial randomization (1:1 allocation) to PCST-Full (5 sessions) or PCST-Brief (1 session) and 5 to 8 weeks later. Responders ( > 30% pain reduction) were rerandomized to a maintenance dose or no dose and nonresponders (<30% pain reduction) to an increased or maintenance dose. Pain severity was assessed again 5 to 8 weeks later (assessment 3) and 6 months later (assessment 4). As hypothesized, PCST-Full resulted in greater mean percent pain reduction than PCST-Brief (M SD = -28.5% 39.6% vs M SD= -14.8% 71.8%; P = 0.041). At assessment 3 after second dosing, all intervention sequences evidenced pain reduction from assessment 1 with no differences between sequences. At assessment 4, all sequences evidenced pain reduction from assessment 1 with differences between sequences ( P = 0.027). Participants initially receiving PCST-Full had greater pain reduction at assessment 4 ( P = 0.056). Varying PCST doses led to pain reduction over time. Intervention sequences demonstrating the most durable decreases in pain reduction included PCST-Full. Pain Coping Skills Training with intervention adjustment based on response can produce sustainable pain reduction.
Abstract
Background. To evaluate the safety and efficacy of moderate-to-high intensity aerobic training in breast cancer patients receiving neoadjuvant chemotherapy. Methods. Twenty patients with ...stage IIB-IIIC operable breast cancer were randomly assigned to receive doxorubicin plus cyclophosphamide (AC) or AC in combination with aerobic training (AC + AET) (n = 10/group) for 12 weeks. The AC+ AET group performed three supervised aerobic cycle ergometry sessions per week at 60%-100% of exercise capacity (VO2peak). Safety outcomes included exercise testing as well as treatment- and exercise training-related adverse events (AEs), whereas efficacy outcomes included cardiopulmonary function and patient-reported outcomes (PROs) as measured by a cardiopulmonary exercise test (CPET) and Functional Assessment of Cancer Therapy-Breast (FACT-B) scale. Results. Twelve non-significant ECG abnormalities and three non-life threatening events occurred during CPET procedures. One AE was reported during aerobic training. There were no significant between group differences for clinician-documented events (e.g. pain, nausea) or hematological parameters (p's > 0.05). Attendance and adherence rates to aerobic training were 82% and 66%, respectively. Intention-to-treat analysis indicated that VO2peak increased by 2.6 ± 3.5 ml/kg/min (+ 13.3%) in the AC + AET group and decreased by 1.5 ± 2.2 ml/kg/min (−8.6%) in the AC group (between group difference, p = 0.001). FACT-B increased 11.1 points in the AC + AET group compared to a 1.5 point decrease in the AC group (between group difference, p = 0.685). Conclusion. Moderate-to-high intensity aerobic training when conducted with one-on-one supervision is a safe adjunct therapy associated with improvements in cardiopulmonary function and select PROs during neoadjuvant chemotherapy.
Background
This study explores the incidence of patient‐reported major toxicity—symptoms rated “moderate,” “severe,” or “very severe”—for chemotherapy regimens commonly used in early breast cancer.
...Patients and Methods
Female patients aged 21 years or older completed a validated Patient‐Reported Symptom Monitoring instrument and rated 17 symptoms throughout adjuvant or neoadjuvant chemotherapy. Fisher's exact tests compared differences in percentages in symptom ratings, and general linear regression was used to model the incidence of patient‐reported major toxicity.
Results
In 152 patients, the mean age was 54 years (range, 24–77), and 112 (74%) were white; 51% received an anthracycline‐based regimen. The proportion of patients rating fatigue, constipation, myalgia, diarrhea, nausea, peripheral neuropathy, and swelling of arms or legs as a major toxicity at any time during chemotherapy varied significantly among four chemotherapy regimens (p < .05). The mean (SD) number of symptoms rated major toxicities was 6.3 (3.6) for anthracycline‐based and 4.4 (3.5) for non‐anthracycline‐based regimens (p = .001; possible range, 0–17 symptoms). Baseline higher body mass index (p = .03), patient‐reported Karnofsky performance status ≤80 (p = .0003), and anthracycline‐based regimens (p = .0003) were associated with greater total number of symptoms rated major toxicities (alternative model: chemotherapy duration, p < .0001). Twenty‐six percent of dose reductions (26 of 40), 75% of hospitalizations (15 of 20), and 94% of treatment discontinuations (15 of 16) were in anthracycline‐based regimens.
Conclusion
Capturing multiple toxicity outcomes throughout chemotherapy enables oncologists and patients to understand the range of side effects as they discuss treatment efficacies. Continuous symptom monitoring may aid in the timely development of interventions that minimize toxicity and improve outcomes.
Implications for Practice
This study investigated patient‐reported toxicities for 17 symptoms recorded prospectively during adjuvant and neoadjuvant chemotherapy regimens for early breast cancer. An analysis of four commonly used chemotherapy regimens identified significant differences among regimens in both individual symptoms and total number of symptoms rated moderate, severe, or very severe. Longer chemotherapy regimens, such as anthracycline‐based regimens followed by paclitaxel, had higher proportions of symptoms rated major toxicities. The inclusion of patient perspectives on multiple toxicity outcomes at the same time at multiple time points during chemotherapy has the potential for improving patient‐provider communication regarding symptom management, patient satisfaction, and long‐term clinical outcomes.
摘要
背景。本研究探索了在常用于治疗早期乳腺癌的化疗方案中患者报告的主要毒性(即被评为“中度”、“重度”或“极重度”的症状)的发生率。
患者和方法。年满 21 岁或以上的女性患者填写一份经验证的患者报告的症状监测文件并对辅助或新辅助化疗期间的 17 个症状进行评级。Fisher's精确检验对症状评级百分比之间的差异进行比较，一般线性回归用于模拟患者报告的主要毒性的发生率。
结果。在 152 名患者中，平均年龄为 54 岁(范围介于 24–77 岁之间)，112 名患者 (74%) 为白种人；51% 的患者接受蒽环类方案治疗。在化疗期间的任何时间将疲劳、便秘、肌痛、腹泻、恶心、周围神经病变以及手臂或腿部肿胀评为主要毒性的患者的比例在 4 个化疗方案中显著不同 (p < 0.05)。在蒽环类方案和非蒽环类方案中，被评为主要毒性的症状的平均数 (SD) 分别为 6.3 (3.6) 和 4.4 (3.5)(p = 0.001；可能的范围，0–17 个症状)。基线较高的体质量指数 (p = 0.03)、患者报告的 Karnofsky 体力状态 ≤80 (p = 0.000 3) 以及蒽环类方案 (p = 0.000 3) 与被评为主要毒性的症状的总数较高相关(替代模式:化疗持续时间，p < 0.000 1)。在蒽环类方案中，剂量减少占 26%(40 名患者中的 26 名患者)，住院治疗占 75%(20 名患者中的 15 名患者)，治疗中断占 94%(16 名患者中的 15 名患者)。
结论。获取化疗过程中的多种毒性结果，可令肿瘤学家和患者在讨论治疗有效性时了解副作用的范围。持续的症状监测可能有助于及时地制定可以最大限度地减少毒性并改进预后的干预措施。
《肿瘤学家》
实践意义:本研究调查了患者报告的早期乳腺癌辅助和新辅助化疗方案中前瞻性记录的 17 个症状的毒性。针对 4 个常用化疗方案的分析在单项症状和被评为“中度”、“重度”或“极重度”的症状的总数方面确定了方案之间的显著差异。在较长的化疗方案中，如后续采用紫杉醇治疗的蒽环类方案，被评为主要毒性的症状占有较高的比例。同时，在化疗期间的多个时间点加入患者关于多种毒性结果的看法，这可能会改进患者和医疗服务提供者之间有关症状管理、患者满意度以及长期临床预后的沟通。
This article focuses on the incidence of patient‐reported major toxicity for chemotherapy regimens commonly used in breast cancer, especially considering the need for patient‐centered assessments of treatment tolerability as an important complement to the NCI's CTCAE.
For breast cancer, guidelines direct the delivery of adjuvant systemic therapy on the basis of lymph node status, histology, tumor size, grade, and hormonal receptor status. We explored how ...race/ethnicity, insurance, census tract-level poverty and education, and hospital Commission on Cancer (CoC) status were associated with the receipt of guideline-concordant adjuvant systemic therapy.
Locoregional breast cancers diagnosed in 2004 (n = 6,734) were from the National Program of Cancer Registries-funded seven-state Patterns of Care study of the Centers for Disease Control and Prevention. Predictors of guideline-concordant (receiving/not receiving) adjuvant systemic therapy, according to National Comprehensive Cancer Network Guidelines, were explored by logistic regression.
Overall, 35% of women received nonguideline chemotherapy, 12% received nonguideline regimens, and 20% received nonguideline hormonal therapy. Significant predictors of nonguideline chemotherapy included Medicaid insurance (odds ratio OR, 0.66; 95% CI, 0.50 to 0.86), high-poverty areas (OR, 0.77; 95% CI, 0.62 to 0.96), and treatment at non-CoC hospitals (OR, 0.69; 95% CI, 0.56 to 0.85), with adjustment for age, registry, and clinical variables. Predictors of nonguideline regimens among chemotherapy recipients included lack of insurance (OR, 0.47; 95% CI, 0.25 to 0.92), high-poverty areas (OR, 0.71; 95% CI, 0.51 to 0.97), and low-education areas (OR, 0.65; 95% CI, 0.48 to 0.89) after adjustment. Living in high-poverty areas (OR, 0.78; 95% CI, 0.64 to 0.96) and treatment at non-CoC hospitals (OR, 0.68; 95% CI, 0.55 to 0.83) predicted nonguideline hormonal therapy after adjustment. ORs for poverty, education, and insurance were attenuated in the full models.
Sociodemographic and hospital factors are associated with guideline-concordant use of systemic therapy for breast cancer. The identification of modifiable factors that lead to nonguideline treatment may reduce disparities in breast cancer survival.
Purpose
We examined acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) events among 9679 women treated for breast cancer on four adjuvant Alliance for Clinical Trials in Oncology trials ...with >90 months of follow-up in order to better characterize the risk for AML/MDS in older patients receiving anthracyclines.
Methods
We used multivariable Cox regression to examine factors associated with AML/MDS, adjusting for age (≥65 vs. <65 years; separately for ≥70 vs. <70 years), race/ethnicity, insurance, performance status, and anthracycline receipt. We also examined the effect of cyclophosphamide, the interaction of anthracycline and age, and outcomes for those developing AML/MDS.
Results
On Cancer and Leukemia Group B (CALGB) 40101, 49907, 9344, and 9741, 7290 received anthracyclines; 15% were in the age ≥65 and 7% were ≥70. Overall, 47 patients developed AML/MDS (30 AML 0.3%, 17 MDS 0.2%); 83% of events occurred within 5 years of study registration. Among those age ≥65 and ≥70, 0.8 and 1.0% developed AML/MDS (vs. 0.4% for age <65), respectively. In adjusted analyses, older age and anthracycline receipt were significantly associated with AML/MDS (adjusted hazard ratio HR for age ≥65 vs. <65 = 3.13, 95% confidence interval CI 1.18–8.33; HR for anthracycline receipt vs. no anthracycline = 5.16, 95% CI 1.47–18.19). There was no interaction between age and anthracycline use. Deaths occurred in 70% of those developing AML/MDS.
Conclusions
We observed an increased risk for AML/MDS for older patients
and
those receiving anthracyclines, though these events were rare. Our results help inform discussions surrounding anticipated toxicities of adjuvant chemotherapy in older patients.
Background
This study investigates whether high body mass index (BMI) in women diagnosed with early breast cancer (BC) is associated with patient-reported symptom severity during chemotherapy.
...Methods
Women with Stage I–III BC completed toxicity reports for 17 side effects throughout regularly scheduled chemotherapy infusions. Toxicity reports were compared in women with obesity (BMI > = 30) versus no obesity (BMI < 30). Fisher’s exact tests and 2-sample
t
-tests compared baseline patient characteristics. Risk ratios (RR) for women with obesity as compared to no obesity were estimated for individual symptoms that were patient-rated as moderate, severe or very severe (MSVS) severity, adjusting for marital status and race.
Results
In a sample of 286 patients, Black women comprised 23% of the sample. The obesity rate was 76% among Black patients and 31% among White patients (
p
< .0001). Women with obesity rated an average of 6.9 side effects (standard deviation, SD 4.2) as MSVS vs 5.5 side effects (SD 3.7) among women with no obesity (
p
= .003). In adjusted analysis, women with obesity had significantly greater risk for MSVS fatigue (RR 1.18, 95% CI 1.01–1.36), dyspnea (RR 1.71, 95% CI 1.09–2.69), arthralgia (RR 1.47, 95% CI 1.10–1.97), peripheral neuropathy (RR 1.45, 95% CI 1.01–2.08), edema of limbs (RR 1.84, 95% CI 1.18–2.88), and abdominal pain (RR 1.75, 95% CI 1.07–2.87). There were no inter-group differences in BC stage or phenotype, chemotherapy treatment modifications, or hospitalizations.
Conclusions
Among women with early BC, patients with obesity reported higher chemotherapy toxicity as compared to patients without obesity; however, this did not result in differences in treatment completion.

Nearly half of all women diagnosed with breast or ovarian cancer are age 65 years or older with the number of women diagnosed expected to increase as the population ages and life expectancy improves. ...Older women are less likely to be offered standard cancer treatments, are more likely to develop higher toxicity, and have higher mortality. Chronologic age should not be the only factor used for making treatment decisions. Functional dependence, organ function, comorbidity, polypharmacy, social support, cognitive and/or psychosocial factors, overall life expectancy, and patient's goals of care are equally vital and should be assessed before and during treatment. In this review, current evidence and treatment guidelines for older women with breast or ovarian cancer are outlined.
