Chemotherapy-induced peripheral neuropathy in the detroit research on cancer survivors (ROCS) cohort.

ABSTRACT:

Purpose

Improved life expectancy has increased the likelihood for long-term complications from chemotherapy among cancer survivors. One burdensome complication is chemotherapy-induced peripheral neuropathy (CIPN). We evaluated rates of CIPN outcomes in the Detroit Research on Cancer Survivorship (ROCS) cohort.

Methods

The population included 1,034 African American (AA) survivors who received chemotherapy for breast, colorectal, lung or prostate cancer. CIPN prevalence was based on initial occurrence of worsening of self-reported pain, numbness or tingling after chemotherapy. Current CIPN included symptoms still present at the time of the survey, and persistent CIPN symptoms were present 12 or more months post-chemotherapy. CIPN severity was ranked as mild, moderate or severe. Logistic regression was utilized to evaluate sociodemographic and clinical factors associated with the various categories of CIPN.

Results

CIPN prevalence was 68%, with 53% current and 52% persistent. The symptom severity distribution based on prevalent CIPN included 32.2% mild, 30.8% moderate, and 36.9% severe. Factors associated with prevalent CIPN (odds ratio, 95% confidence interval) included primary cancer site (breast: 3.88, 2.02-7.46); and (colorectal: 5.37, 2.69-10.73), lower risk for older age at diagnosis (0.66, 0.53-0.83) and divorced/separated marital status (2.13, 1.42-3.21). Current CIPN was in addition, associated with more advanced stage disease trend (1.34, 1.08-1.66) and greater number of co-morbid medical conditions trend (1.23, 1.09-1.40), as was persistent CIPN. Severity of prevalent CIPN was associated with history of arthritis (1.55, 1.06-2.26) and severity of persistent CIPN with higher BMI (1.58, 1.07-2.35).

Conclusions

CIPN is a common and persistent complication in AA cancer survivors. Further research is needed to improve our understanding of CIPN predictors in all groups of cancer survivors.

Project description:Chemotherapy is a common treatment for breast cancer (BrCa) and can cause chemotherapy-induced peripheral neuropathy (CIPN). CIPN contributes to falls, and is thus a potential risk factor for nontraumatic fractures (NTFx); yet, the effect of CIPN on NTFx risk has not been examined for BrCa survivors. We therefore investigated the association between CIPN and NTFx in BrCa survivors. Data were extracted from Optum's Deidentified Clinformatics® Data Mart Database years 2010-2015 in this retrospective cohort study. Among women, three groups were derived based on BrCa and CIPN status: BrCa+/CIPN+ (primary group of interest), BrCa+/CIPN- (first comparison group), and BrCa-/CIPN- (second comparison group). After propensity score matching the comparison groups to BrCa+/CIPN+ at a ratio of 1:11 (BrCa:control) for demographics, osteoporosis, glucocorticoid medication, comorbidities, and cancer-related variables for BrCa+/CIPN-, 1-year incidence rate (IR) of NTFx was determined for each group. The incident rate ratio (IRR) determined if the IR for NTFx was different for BrCa+/CIPN+ compared to BrCa+/CIPN- and BrCa-/CIPN-. Cox proportional hazards regression models estimated the hazard ratios (HRs) after adjusting for covariates that were unable to be matched for. The crude IR (95% confidence interval [CI]) of NTFx was 4.54 (2.32-6.77) for BrCa+/CIPN+ (n = 359), 2.53 (2.03-3.04) for BrCa+/CIPN- (n = 3949), and 1.76 (1.35-2.18) for BrCa-/CIPN- (n = 3949). The crude IRR of NTFx was significantly elevated for BrCa+/CIPN+ as compared to BrCa+/CIPN- (IRR = 1.80; 95% CI, 1.06-3.05) and BrCa-/CIPN- (IRR = 2.58; 95% CI, 1.50-4.44). The elevated rate of NTFx for BrCa+/CIPN+ remained unchanged after adjusting for aromatase inhibitors compared to BrCa+/CIPN- (HR = 1.79; 95% CI, 1.06-3.04). Female BrCa survivors have an increased 1-year IR of NTFx after the onset of CIPN, suggesting that CIPN is an additive burden on NTFx risk among BrCa survivors. © 2021 The Authors.

Project description:BackgroundAfrican Americans are often diagnosed with advanced stage cancer and experience higher mortality compared with whites in the United States. Contributing factors, like differences in access to medical care and the prevalence of comorbidities, do not entirely explain racial differences in outcomes.MethodsThe Detroit Research on Cancer Survivors (ROCS) pilot study was conducted to investigate factors related to short- and long-term outcomes among patients with cancer. Participants completed web-based surveys, and mailed saliva specimens were collected for future genetic studies.ResultsWe recruited 1,000 participants with an overall response rate of 68%. Thirty-one percent completed the survey without any interviewer support and the remaining participated in an interviewer-administered survey. Seventy-four percent provided a saliva specimen and 64% consented for tumor tissue retrieval. African American survivors required more interviewer support (P < 0.001); however, their response rate (69.6%) was higher than non-Hispanic whites (65.4%). African Americans reported poorer overall cancer-related quality of life compared with non-Hispanic whites, measured by FACT-G score (P < 0.001), however, this relationship was reversed after controlling for socioeconomic factors, marital status, and the presence of comorbidities.ConclusionsIn this pilot study, we demonstrated that a web-based survey supplemented with telephone interviews and mailed saliva kits are cost-effective methods to collect patient-reported data and DNA for large studies of cancer survivors with a high proportion of minority patients. The preliminary data collected reinforces differences by race in factors affecting cancer outcomes. Our efforts continue as we expand this unique cohort to include more than 5,000 African American cancer survivors.ImpactFormal investigation of factors influencing adverse outcomes among African American cancer survivors will be critical in closing the racial gap in morbidity and mortality.

Project description:BackgroundChemotherapy-induced peripheral neuropathy (CIPN) is one of the most debilitating long-term side effects in breast cancer survivors. We conducted a randomized controlled pilot trial to assess the feasibility, safety, and effects of an acupuncture intervention on CIPN in this population.Patients and methodsWomen with stage I-III breast cancer with grade 1 or higher CIPN after taxane-containing adjuvant chemotherapy were randomized 1:1 to an immediate acupuncture (IA) arm or to a waitlist control group (CG). Participants in the IA arm received 18 sessions of acupuncture over 8 weeks, then received no additional acupuncture. Patients in the CG arm received usual care over 8 weeks, followed by nine sessions of acupuncture over 8 weeks. Measures including Patient Neurotoxicity Questionnaire (PNQ), Functional Assessment of Cancer Therapy-Neurotoxicity subscale (FACT-NTX), and Brief Pain Inventory-short form (BPI-SF) were collected at baseline and at 4, 8, and 16 weeks after enrollment.ResultsForty women (median age, 54) were enrolled (20 to IA and 20 to CG), with median time between completion of chemotherapy and enrollment of 14 months (range 1-92). At 8 weeks, participants in the IA arm experienced significant improvements in PNQ sensory score (-1.0 ± 0.9 vs. -0.3 ± 0.6; p = .01), FACT-NTX summary score (8.7 ± 8.9 vs. 1.2 ± 5.4; p = .002), and BPI-SF pain severity score (-1.1 ± 1.7 vs. 0.3 ± 1.5; p = .03), compared with those in the CG arm. No serious side effects were observed.ConclusionWomen with CIPN after adjuvant taxane therapy for breast cancer experienced significant improvements in neuropathic symptoms from an 8-week acupuncture treatment regimen. Additional larger studies are needed to confirm these findings.Implications for practiceChemotherapy-induced peripheral neuropathy (CIPN) is a toxicity that often persists for months to years after the completion of adjuvant chemotherapy for early breast cancer. In a randomized pilot trial of 40 breast cancer survivors with CIPN, an 8-week acupuncture intervention (vs. usual care) led to a statistically and clinically significant improvement in subjective sensory symptoms including neuropathic pain and paresthesia. Given the lack of effective therapies and established safety profile of acupuncture, clinicians may consider acupuncture as a treatment option for mild to moderate CIPN in practice.

Project description:BackgroundEpidemiological studies of chemotherapy-induced peripheral neuropathy (CIPN) have predominantly focused on non-Hispanic White patients, despite the observation that African Americans are more likely to experience CIPN. To address this health disparities gap, we sought to identify non-genetic risk factors and comorbidities associated with CIPN in African American cancer survivors using the Detroit Research on Cancer Survivors study.MethodsLogistic regression was used to evaluate relationships between presence of self-reported CIPN and relevant clinical characteristics in 1045 chemotherapy-treated African American cancer survivors. Linear regression was used to evaluate risk factors for CIPN and quality of life outcomes that reflect physical, social, emotional, and functional domains of health.ResultsPatients with CIPN were more likely to report hypertension (OR = 1.28, 95% CI: 0.98-1.67, p = 0.07), hypercholesterolemia (OR = 1.32, 95% CI: 1.001-1.73, p = 0.05), history of depression (OR = 1.62, 95% CI: 1.18-2.25, p = 0.003), and diabetes (OR = 1.33, 95% CI: 0.98-1.82, p = 0.06) after adjustment for age at diagnosis, sex, and cancer site. BMI (OR = 1.02 kg/m2 , 95% CI: 1.006-1.04 kg/m2 , p = 0.008) was also positively associated with CIPN. In addition, CIPN status was significantly associated with quality of life (FACT-G total: β = -8.60, 95% CI: -10.88, -6.32) p < 0.0001) and mood (PROMIS® Anxiety: β = 4.18, 95% CI: 2.92-5.45, p < 0.0001; PROMIS® Depression: β = 2.69, 95% CI: 1.53-3.84, p < 0.0001) after adjustment for age at diagnosis, sex, cancer site, and comorbidities. Neither alcohol consumption (OR = 0.88, 95% CI: 0.68-1.14, p = 0.32) nor tobacco use (ever smoked: OR = 1.04, 95% CI: 0.80-1.35, p = 0.76; currently smoke: OR = 1.28, 95% CI: 0.90-1.82, p = 0.18) was associated with increased CIPN risk.ConclusionRisk factor profiles in African Americans are not entirely consistent with those previously reported for non-Hispanic White patients. Neglecting to understand the correlates of common chemotherapy-induced toxicities for this patient population may further contribute to the health disparities these individuals face in receiving adequate healthcare.
