Cognitive function, fatigue, and menopausal symptoms in breast cancer patients receiving adjuvant chemotherapy: evaluation with patient interview after formal assessment

BACKGROUND: Women who receive adjuvant chemotherapy for breast cancer report fatigue, menopausal symptoms and cognitive problems. Here we compare assessment of these symptoms using self-report questionnaires and a researcher-administered screen of cognitive function with the experience of women as revealed in a semi-structured interview. METHODS: Twenty-one women who were receiving adjuvant chemotherapy completed the Functional Assessment of Cancer Treatment-General (FACT-G) self-report questionnaire, and sub-scales for fatigue (FACT-F) and endocrine symptoms (FACT-ES). They were evaluated for cognitive dysfunction using the High Sensitivity Cognitive Screen (HSCS). They then completed a semi-structured interview, which explored the nature and severity of these symptoms and their impact on daily function. RESULTS: All patients experienced fatigue and most had menopausal symptoms. There was reasonable correlation of findings in the interview with FACT-F and FACT-ES scores. The HSCS revealed fewer problems than were reported by patients, and correlated with patient experience only for the domain of memory. Most patients noted adverse changes in other cognitive domains, especially concentration, with substantial effects on every-day function. CONCLUSIONS: Women receiving adjuvant chemotherapy for breast cancer have substantial problems with fatigue, menopausal symptoms and cognitive changes. Formal tests such as the HSCS may fail to adequately capture the perceived impact of symptoms.     

Cognitive function, fatigue, and menopausal symptoms in women receiving adjuvant chemotherapy for breast cancer.

PURPOSE: There is evidence that cognitive dysfunction, fatigue, and menopausal symptoms may occur in women receiving adjuvant chemotherapy for breast cancer. Here, we determine their incidence and severity, and interrelationships between them and quality of life. PATIENTS AND METHODS: In this study, 110 women receiving adjuvant chemotherapy each nominated a female relative, friend, or neighbor (matched by age) as a control; 100 eligible matched pairs were evaluated. Patients and controls completed the following assessments: the High-Sensitivity Cognitive Screen, and the Functional Assessment of Cancer Therapy-General (FACT-G) quality of life scale with subscales for fatigue (FACT-F) and endocrine symptoms (FACT-ES). They also performed tests of attention and reaction time. RESULTS: Patients and controls were well matched for age and level of education. There was a higher incidence of moderate or severe cognitive impairment in the patient group (16% v 4%; P =.008). Patients experienced much more fatigue than controls (median FACT-F scores, 31 v 46; P <.0001) and more menopausal symptoms (median FACT-ES scores, 58 v 64; P <.0001). Self-reported quality of life of the patients was poorer than for controls, especially in physical and functional domains (median FACT-G scores, 77 v 93; P <.0001). There was strong correlation between fatigue, menopausal symptoms, and quality of life (P <.0001 for each pair), but none were significantly associated with the presence of cognitive dysfunction. CONCLUSION: Adjuvant chemotherapy causes cognitive dysfunction, fatigue, and menopausal symptoms in women with breast cancer. Priority should be given to the study of strategies that might reduce these toxic effects.     

The influence of sex and histology on outcomes in non-small-cell lung cancer: a pooled analysis of five randomized trials

Background: Some non-small-cell lung cancer (NSCLC) surgical series have indicated that the positive prognostic effect of female sex is limited to patients with adenocarcinoma. We carried out a retrospective analysis to investigate the role of sex and histology on efficacy, toxicity, and dose delivery after chemotherapy.Patient and methods: Individual patient data were pooled from five randomized, phase III, advanced NSCLC chemotherapy trials. Primary outcomes were response rate, overall survival (OS), toxicity, and dose delivery. A secondary analysis examined survival by sex in histological subgroups.Results: Of 2349 patients, 34% were women. Women had a higher response rate to chemotherapy (42% versus 40%, P = 0.01) and longer survival than men (median OS 9.6 versus 8.6 months, P = 0.002). The difference in OS remained after adjusting for age, stage, performance status, and histology (hazard ratio 0.83, 95% confidence interval 0.74–0.92, P = 0.0005). Upon further examination, longer survival in women was only seen in patients with adenocarcinoma (test for interaction P = 0.006). There were no differences in hematological toxicity or transfusions. Women experienced more grade 3–4 emesis than men (P < 0.0001) and more dose delays (P = 0.02) or dose reductions (P < 0.0001).Conclusion: The positive prognostic effect among women is confirmed in patients receiving platinum-based chemotherapy but appears confined to those with adenocarcinoma histology.     

Fatigue in people with localized colorectal cancer who do and do not receive chemotherapy: a longitudinal prospective study

BackgroundFatigue is associated with cancer and chemotherapy and may be sustained. Here, we describe a prospective longitudinal study evaluating fatigue and putative mechanisms in people with colorectal cancer (CRC).Patients and methodsPeople with localized CRC completed the Functional Assessment of Cancer Treatment-Fatigue (FACT-F) questionnaire at baseline (before chemotherapy, if given), 6, 12, and 24 months. Healthy controls (HCs) were assessed at the first three time points. Fatigue was defined by standardized FACT-F scores ≤68/100. Quality-of-life (QoL, assessed by the FACT-G questionnaire), affective, and cognitive symptoms were evaluated. Associations were sought between fatigue, baseline factors, and blood tests (including hemoglobin, cytokines, and sex hormones). Regression analyses, Fisher's exact tests, and Wilcoxon rank-sum tests assessed levels of fatigue at each time point and change in fatigue from baseline. A repeated-measures analysis investigated prognostic factors of fatigue across all time points.ResultsA total of 289 subjects with localized CRC (173 received chemotherapy) and 72 HCs were assessed. More CRC patients had fatigue than HCs at baseline (52% versus 26%, P < 0.001). Fatigue was increased in the chemotherapy (CTh) group at 6 months [CTh+ 70% versus CTh- 31% (P < 0.001), HCs 22%] and remained more common at 12 [CTh+ 44% versus CTh- 31% (P = 0.079)] and 24 months [CTh+ 39% versus CTh- 24% (P = 0.047)]. There was no significant difference between those not receiving chemotherapy and HCs at follow-up assessments. Fatigue was associated with poor QoL, affective and cognitive symptoms, but not consistently with cytokine levels. Predictors for sustained fatigue were baseline fatigue, treatment group, cognitive and affective symptoms, poorer QoL, and comorbidities.ConclusionsCRC patients have more fatigue than HCs at baseline. Fatigue peaks immediately after adjuvant chemotherapy, but remains common for 2 years in those who receive chemotherapy. Cognitive and affective symptoms, QoL, comorbidities, chemotherapy, and baseline fatigue predict for longer term fatigue.     

Menopausal symptoms and bone health in women undertaking risk reducing bilateral salpingo-oophorectomy: significant bone health issues in those not taking HRT

Background:

Women at high ovarian cancer risk, especially those with mutations in BRCA1/BRCA2, are encouraged to undergo bilateral risk-reducing salpingo-oophorectomy (BRRSPO) prior to the natural menopause. The decision to use HRT to cover the period of oestrogen deprivation up to 50 years of age is difficult because of balancing the considerations of breast cancer risk, bone and cardiovascular health.

Methods:

We reviewed by questionnaire 289 women after BRRSPO aged ⩽48 years because of high ovarian cancer risk; 212 (73%) of women responded.

Results:

Previous HRT users (n=67) had significantly worse endocrine symptom scores than 67 current users (P=0.006). A total of 123 (58%) of women had ⩾24 months of oestrogen deprivation <50 years with 78 (37%) never taking HRT. Bone density (DXA) evaluations were available on 119 (56%) women: bone loss with a T score of ⩽−1.0 was present in 5 out of 31 (16%) women with no period of oestrogen deprivation <50 years compared with 37 out of 78 (47%) of those with ⩾24 months of oestrogen deprivation (P=0.03).

Interpretation:

Women undergoing BRRSPO <50 years should be counselled concerning the risks/benefits of HRT, taking into consideration the benefits on symptoms, bone health and cardiovascular health, and that the risks of breast cancer from oestrogen-only HRT appear to be relatively small.     

Cognitive function and fatigue after diagnosis of colorectal cancer

BackgroundCognitive impairment and fatigue have been associated with cancer and its treatment. We present baseline data from a large longitudinal study that evaluates cognitive function, fatigue, and potential underlying mechanisms following diagnosis of colorectal cancer (CRC).Patients and methodsWe evaluated CRC patients with stage I–III disease before or after surgery, participants with limited metastatic disease and healthy controls (HC). Neuropsychological evaluation included clinical and computerised tests. Participants completed questionnaires for fatigue and quality of life (QOL)-(FACT-F), anxiety/depression, and cognitive symptoms (FACT-Cog). Ten cytokines, clotting factors, sex hormones, carcinoembryonic antigen (CEA), and apolipoprotein E genotype were evaluated. Primary end points were cognitive function on clinical tests evaluated by a Global Deficit score (GDS) and fatigue. Associations between test results, demographic, and disease related factors were explored.ResultsWe assessed 291 participants with early-stage disease [median age 59 (23–75) years, 63% men], 72 with metastatic disease, and 72 HC. Using GDS, 45% (126/281) of participants with early-stage CRC had cognitive impairment versus 15% (11/72) of HC (odds ratio 4.51, 95% confidence interval 2.28–8.93; P < 0.001), with complex processing speed, attention/working memory, and verbal learning efficiency being most affected. Women with early-stage CRC had greater cognitive impairment than men [55/105 (52%) versus 71/176 (40%), P < 0.050]. Cognitive symptoms were self-reported by 21% (59/286) of early-stage patients versus 17% (12/72) of HC; fatigue by 52% (149/287) of early-stage patients and 26% (19/72) of HC (P < 0.0001). Women reported more fatigue than men (P = 0.003). Fatigue, QOL, anxiety/depression, and cognitive symptoms were associated with each other (r = 0.43–0.71), but not with neuropsychological performance. Most cytokines were elevated in cancer patients. Cognitive function was not associated with cytokines, sex hormones, clotting factors, CEA, or apolipoprotein E genotype.ConclusionsThe incidence of cognitive impairment was three to five times higher in CRC patients than HC, with women having higher impairment rates than men. The cognitive impairment profile suggests dysfunction primarily in fronto-subcortical brain systems.Trial registrationNCT00188331.     

CT response of primary tumor and CA19-9 predict resectability of metastasized pancreatic cancer after FOLFIRINOX

BackgroundEffective chemotherapy protocols are currently changing the treatment options for metastasized pancreatic cancer. Survival benefits after synchronous metastasectomy have been reported for selected patients. We set out to assess predictive factors of resectability for synchronous metastases after FOLFIRINOX.MethodsConsecutive patients with metastatic pancreatic cancer undergoing surgery after FOLFIRINOX between 2011 and 2017 were identified from a prospectively collected database. Surgery following chemotherapy was indicated in patients with no more than six metastatic lesions, no progression detected on CT, and technically resectable disease. Patients who received synchronous metastasectomy were compared with patients who received explorative laparotomy or palliative surgery in terms of predictors of resectability and overall survival. In patients undergoing resection, prognostic factors were examined.ResultsOf 101 patients scheduled for surgery after FOLFIRINOX, synchronous metastasectomy was performed in 43 cases (43%) and non-resection surgery in 58 cases (57%). The shrinkage rate of the primary tumor on CT (P = 0.04) and the postchemotherapy serum CA19-9 concentration (P = 0.02) were associated with resectability. The median overall survival of the patients undergoing metastasectomy was longer than that of the patients without resection (21.9 months vs 16.4 months, P = 0.006). Postchemotherapy serum CA19-9 value (P = 0.04) and lymph node ratio (P = 0.01) were prognostic factors in the patients undergoing metastasectomy.ConclusionsIn selected patients who satisfied our surgical criteria, shrinkage rate of primary tumor and postchemotherapy serum CA19-9 level, which predict resectability of metastasized pancreatic cancer, should be considered in decision making to avoid unnecessary surgery.     

Incidence of Chemotherapy-Induced Amenorrhea in Premenopausal Women Treated With Adjuvant FOLFOX for Colorectal Cancer

BackgroundStudies indicate that the incidence of young women diagnosed with colorectal cancer is rising, thus there is an increasing number of female colorectal cancer survivors of premenopausal and child-bearing age. Adjuvant FOLFOX (5-fluorouracil, leucovorin, and oxaliplatin) chemotherapy is the most widely used standard treatment for stage III and high-risk stage II colon cancer. We evaluated the incidence of FOLFOX-induced amenorrhea in women age 50 and younger treated with adjuvant therapy for colorectal cancer.Patients and MethodsA search of pharmacy records identified 119 women age 50 or younger who received adjuvant FOLFOX chemotherapy at Memorial Sloan-Kettering for stage II or III colorectal cancer from January 2002 and January 2011. Eligible patients were mailed an anonymous questionnaire. The returned surveys were reviewed and the results tallied.ResultsSeventy-three patients returned the questionnaire. Twenty-four patients were excluded from analysis: 19 were treated with pelvic radiotherapy, 2 patients had undergone bilateral oophorectomy, 2 had a hysterectomy, and 1 stopped menstruating before diagnosis. Forty-nine patient responses were analyzed. In total, 41% (n = 20) experienced amenorrhea during chemotherapy. Sixteen percent had persistent amenorrhea 1 year after completion of chemotherapy. The incidence of amenorrhea during chemotherapy trended higher in patients aged older than 40 compared with patients aged 40 and younger (59% vs. 31% [P = .075]). There was no statistically significant difference in persistent amenorrhea between the 2 age groups (24% vs. 13%; P = .42).ConclusionIn this retrospective series, there appears to be a trend toward FOLFOX induced amenorrhea during chemotherapy increasing with age. Twenty-four percent of women older than the age of 40 were found to have persistent amenorrhea after FOLFOX therapy. Because of the small sample size, the study is underpowered to detect a statistically significant difference between older and younger patients. Prospective studies are planned to further characterize the effect of FOLFOX on early menopause and fertility.     

Prevalence and predictors of fatigue in glioblastoma: a prospective study

BackgroundThe main goal of this study was to assess frequency, clinical correlates, and independent predictors of fatigue in a homogeneous cohort of well-defined glioblastoma patients at baseline prior to combined radio-chemotherapy.MethodsWe prospectively included 65 glioblastoma patients at postsurgical baseline and assessed fatigue, sleepiness, mean bedtimes, mood disturbances, and clinical characteristics such as clinical performance status, presenting symptomatology, details on neurosurgical procedure, and tumor location and diameter as well as pharmacological treatment including antiepileptic drugs, antidepressants, and use of corticosteroids. Data on fatigue and sleepiness were measured with the Fatigue Severity Scale and the Epworth Sleepiness Scale, respectively, and compared with 130 age- and sex-matched healthy controls.ResultsWe observed a significant correlation between fatigue and sleepiness scores in both patients (r = 0.26; P = .04) and controls (r = 0.36; P < .001). Only fatigue appeared to be more common in glioblastoma patients than in healthy controls (48% vs 11%; P < .001) but not the frequency of sleepiness (22% vs 19%; P = .43). Female sex was associated with increased fatigue frequency among glioblastoma patients but not among control participants. Multiple linear regression analyses identified depression, left-sided tumor location, and female sex as strongest associates of baseline fatigue severity.ConclusionsOur findings indicate that glioblastoma patients are frequently affected by fatigue at baseline, suggesting that factors other than those related to radio- or chemotherapy have significant impact, particularly depression and tumor localization.     

Sex Disparities in Myelodysplastic Syndromes: Genotype,Phenotype, and Outcomes

Introduction/Background The impact of biological sex on the clinical phenotype, genotype, and outcomes among patients with MDS is not well characterized. Materials and Methods We retrospectively reviewed the clinical and genomic data from male and female patients included in our institutional MDS database at Moffitt Cancer Center. Results Among 4580 patients with MDS, 2922 (66%) were men and 1658 (34%) were women. Women were younger (mean age 66.5 vs. 69 years for men, P < .001) at diagnosis. There were more Hispanic/black women than men (9% vs. 5%, P =<.001). Women had lower hemoglobin and higher platelet counts than men. More women had del 5q/monosomy 5 abnormalities compared to men (P =<.001). Therapy related MDS were more common in women than men (25% vs.17%, P=<.001). On assessment of molecular profile, SRSF2, U2AF1, ASXL1, and RUNX1 mutations were more frequent in men. The median overall survival (mOS) was 37.5 months (mo) for females compared to 35 monthsfor males, (P = .002). The mOS was significantly prolonged for women in lower-risk MDS, but not in higher-risk MDS. Women were more likely to respond to immunosuppression with ATG/CSA than men (38% vs. 19%, P= 0.04).Conclusion Ongoing research is needed for understanding the impact of sex on phenotype, genotype, and outcomes in patients diagnosed with MDS.     

Effect of Exercise on Taxane Chemotherapy–Induced Peripheral Neuropathy in Women With Breast Cancer: A Randomized Controlled Trial

BackgroundChemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting adverse effect of taxanes. We sought to evaluate the effect of exercise on taxane CIPN in women with breast cancer.Patients and MethodsWomen (n = 27) were randomized to immediate exercise (IE, during taxane chemotherapy) or delayed exercise (DE, after chemotherapy). Supervised aerobic, resistance, and balance training was offered 3 days a week for 8-12 weeks. CIPN symptoms and quality of life were assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) C30 and CIPN20 (scored from 0 to 100). The percentage of participants reporting moderate to severe sensory symptoms (‘3/4’ or ‘4/4’ for CIPN20 sensory items) was also evaluated, along with clinical sensory testing at the lower limb (vibration sense and pinprick). Taxane treatment adherence, including relative dose intensity, was extracted from patient medical records. Assessments occurred at: baseline (before taxane chemotherapy), pre-cycle 4 (before the final taxane cycle), the end of chemotherapy, and follow-up (10-15 weeks after chemotherapy).ResultsNo differences in the EORTC QLQ CIPN20 symptom scores were detected between groups at any time point. At pre-cycle 4, there was a significant difference between groups in patient-reported moderate to severe numbness in the toes or feet (IE: n = 1, 9%, DE: n = 7, 50%, P = .04) and impaired vibration sense in the feet (IE: n = 2, 18%, DE: n = 10, 83%, P < .01). Overall global health status/quality of life was higher in IE compared to DE at the end of chemotherapy (P = .05), yet both groups had worse CIPN20 sensory (Δ24.3 ± 4.6, P < .01) and motor symptom scores (Δ10.5 ± 1.9, P < .01) relative to baseline. By the end of chemotherapy, no differences between groups were found for moderate to severe numbness in the toes or feet (P = 1.0) or impaired vibration sense in the feet (P = .71). More IE participants received ≥ 85% relative dose intensity (IE: n = 12, 100%, DE: n = 10, 67%, P < .05).ConclusionExercise may attenuate CIPN over the course of taxane chemotherapy and possibly improve taxane adherence in women with breast cancer. These findings, as well as whether exercise can attenuate CIPN by the end of taxane chemotherapy, should be confirmed in larger trials.     

A prognostic model based on nodal status and Ki-67 predicts the risk of recurrence and death in breast cancer patients with residual disease after preoperative chemotherapy

Background: Preoperative chemotherapy (PCT) allows for in vivo testing of treatment effects on tumor and its microenvironment. Aim of this analysis was to evaluate the effect of PCT on tumor biomarker expression and to evaluate the prognostic role of treatment-induced variation of these biomarkers (molecular response).Methods: Two hundred and twenty-one stage II–III breast cancer patients were included. The following parameters were evaluated at baseline and on surgical specimens after PCT: estrogen receptor (ER), progesterone receptor (PgR), human epidermal growth factor receptor 2 (HER2), Ki-67, p53, human epidermal growth factor receptor (EGFR), vascular endothelial growth factor receptor 2 (VEGFR2), and apoptosis.Results: A pathological complete response was observed in 8.8% of the patients. PCT induced a significant reduction in the expression of ER, PgR, Ki-67, and apoptosis. As by multivariable model, Ki-67 ≥15% and nodal positivity after preoperative chemotherapy (PCT) were significant predictors of worse disease-free survival [hazard ratio (HR) 3.79, P < 0.0001 and HR 2.31, P = 0.037, respectively]. Ki-67 ≥15% after PCT was also a significant predictor of overall survival (HR 3.75, P = 0.013). On the basis of these two parameters, patients were classified into three groups: (i) low risk (negative nodes and Ki-67 <15%), (ii) intermediate risk (nodal positivity or Ki-67 ≥15%), and (iii) high risk (nodal positivity and Ki-67 ≥15%). As compared with the low-risk group, the HRs for recurrence were 3.1 and 9.3 for the intermediate- and high-risk group, respectively (P = 0.0001); the HRs for death were 2.4 and 6.5 for the intermediate- and high-risk group, respectively (P = 0.042).Conclusions: Ki-67 and nodal status have been used to generate a simple and easily reproducible prognostic model, able to discriminate patients with worse prognosis among the heterogeneous group of women with residual disease after PCT.     

Improved time to progression for transarterial chemoembolization compared with transarterial embolization for patients with unresectable hepatocellular carcinoma

BackgroundEmbolizing branches of the hepatic artery lengthens survival for patients with unresectable hepatocellular carcinoma (HCC), but the benefit of combining chemotherapy with the embolizing particles remains controversial.MethodsA retrospective review was undertaken of sequential patients with advanced HCC undergoing embolization in the past 10 years at 2 neighboring institutions and with 2 years of follow-up data. TACE was generally performed with doxorubicin plus mitomycin C. Results: One hundred twenty-four patients were included; 77 received TACE and 47 received TAE. On multivariable analysis stratified by institution, type of embolization and CLIP score significantly predicted PFS and time to progression (TTP), whereas CLIP score and AFP independently predicted overall survival (OS). TACE significantly prolonged PFS and TTP (P = .0004 and P = .001, respectively), but not OS (P = .83).ConclusionsThe addition of chemotherapy to TAE prolongs PFS and TTP. Future efforts should focus on adjunctive therapies after the embolization to increase survival.     

Neuromarkers of fatigue and cognitive complaints following chemotherapy for breast cancer: a prospective fMRI investigation

The aim of this study is to use functional magnetic resonance imaging (fMRI) to prospectively examine pre-treatment predictors of post-treatment fatigue and cognitive dysfunction in women treated with adjuvant chemotherapy for breast cancer. Fatigue and cognitive dysfunction often co-occur in women treated for breast cancer. We hypothesized that pre-treatment factors, unrelated to chemotherapy per se, might increase vulnerability to post-treatment fatigue and cognitive dysfunction. Patients treated with (n = 28) or without chemotherapy (n = 37) and healthy controls (n = 32) were scanned coincident with pre- and one-month post-chemotherapy during a verbal working memory task (VWMT) and assessed for fatigue, worry, and cognitive dysfunction. fMRI activity measures in the frontoparietal executive network were used in multiple linear regression to predict post-treatment fatigue and cognitive function. The chemotherapy group reported greater pre-treatment fatigue than controls and showed compromised neural response, characterized by higher spatial variance in executive network activity, than the non-chemotherapy group. Also, the chemotherapy group reported greater post-treatment fatigue than the other groups. Linear regression indicated that pre-treatment spatial variance in executive network activation predicted post-treatment fatigue severity and cognitive complaints, while treatment group, age, hemoglobin, worry, and mean executive network activity levels did not predict these outcomes. Pre-treatment neural inefficiency (indexed by high spatial variance) in the executive network, which supports attention and working memory, was a better predictor of post-treatment cognitive and fatigue complaints than exposure to chemotherapy per se. This executive network compromise could be a pre-treatment neuromarker of risk, indicating patients most likely to benefit from early intervention for fatigue and cognitive dysfunction.     

Correlation Between Hemoglobin and Fatigue in Women Undergoing Adjuvant Chemotherapy Without Erythropoietin-Stimulating–Agent Support

BackgroundFatigue is a common complication of adjuvant chemotherapy and compromises the quality of life of breast cancer survivors. We sought to correlate serial hemoglobin (Hb) levels with fatigue in a population of women on adjuvant chemotherapy, none of whom received erythropoietin-stimulating agents or red blood cell transfusions.Patients and MethodsSeventy-five women participated in a study using quality-of-life questionnaires to assess changes in need for psychosocial support over time. Questionnaires were administered within 30 days of initiating adjuvant therapy and at 2, 6, and 12 months. Fatigue was assessed by the 36-Item Short-Form Health Survey (SF-36). Hemoglobin levels at each time point were captured retrospectively. Complete data are included for 40 of the 46 women who received adjuvant chemotherapy. Paired-samples t tests were conducted to compare mean SF-36 Energy/Fatigue scores between time points, and independent-samples t tests were conducted for comparisons against norms. Simple correlations (Pearson R) were conducted between SF-36 variables and Hb levels at each time point.ResultsAt 2 months, 23.4% of women had Hb < 11 g/dL compared with 12.9% at 12 months. Compared with norms for women in the general population and breast cancer survivors, these women reported worse fatigue at baseline and at 2 and 6 months. A strong linear relationship was observed between Hb at 2 months and SF-36 Energy/Fatigue scores at 12 months (r = 0.71; P = .002).ConclusionParticipants with high fatigue at 12 months had Hb levels at 2 months 13% lower than those with low fatigue. This finding suggests that chemotherapy-induced decline in Hb might be a marker of physiologic reserve.     

Weekly docetaxel versus CMF as adjuvant chemotherapy for older women with early breast cancer: final results of the randomized phase III ELDA trial

Evidence on adjuvant chemotherapy for elderly early breast cancer patients is poor, due to the low number of phase 3 trials. ELDA shows that weekly docetaxel does not prolong DFS compared with standard CMF and worsens quality of life. Non-hematological toxicity is worse with weekly docetaxel. Age, comorbidities and functioning geriatric scales may be predictive of non-hematological side effects.BackgroundEvidence on adjuvant chemotherapy in older women with breast cancer is poor. We tested whether weekly docetaxel is more effective than standard chemotherapy.Patients and methodsWe carried out a multicenter, randomized phase III study. Women aged 65–79, operated for breast cancer, with average to high risk of recurrence, were allocated 1 : 1 to CMF (cyclophosphamide 600 mg/m², methotrexate 40 mg/m², fluorouracil 600 mg/m², days 1, 8) or docetaxel (35 mg/m² days 1, 8, 15) every 4 weeks, for four or six cycles according to hormone receptor status. Primary end point was disease-free survival (DFS). A geriatric assessment was carried out. Quality of life (QoL) was assessed with EORTC C-30 and BR-23 questionnaires.ResultsFrom July 2003 to April 2011, 302 patients were randomized and 299 (152 allocated CMF and 147 docetaxel) were eligible. After 70-month median follow-up, 109 DFS events were observed. Unadjusted hazard ratio (HR) of DFS for docetaxel versus CMF was 1.21 [95% confidence interval (CI) 0.83–1.76,P = 0.32]; DFS estimate at 5 years was 0.69 with CMF and 0.65 with docetaxel. HR of death was 1.34 (95% CI 0.80–2.22,P = 0.26). There was no interaction between treatment arms and geriatric scales measuring patients' ability or comorbidities. Hematological toxicity, mucositis and nausea were worse with CMF; allergy, fatigue, hair loss, onychopathy, dysgeusia, diarrhea, abdominal pain, neuropathy, cardiac and skin toxicity were worse with docetaxel. One death was attributed to CMF and two to docetaxel. Increasing age, impairment in instrumental daily living activities, number of comorbidities and docetaxel treatment were independently associated with severe nonhematological toxicity. QoL was worse with docetaxel for nausea-vomiting, appetite loss, diarrhea, body image, future perspective, treatment side-effects and hair loss items.ConclusionsWeekly docetaxel is not more effective than standard CMF as adjuvant treatment of older women with breast cancer and worsens QoL and toxicity.ClinicalTrials.govNCT00331097.     

Effects of Adjuvant Chemotherapy on Cognitive Function of Patients With Early-stage Colorectal Cancer

Purpose

Chemotherapy-related cognitive impairment can occur in cancer survivors after treatment, especially those patients who have undergone chemotherapy for breast cancer. The frequency and to what extent such toxicity develops in colorectal cancer (CRC) survivors is unknown. The present prospective study evaluated the effects of adjuvant chemotherapy on the cognitive performance of patients with localized CRC compared with a control group who had not undergone chemotherapy.

Assessment of quality of life in women undergoing hormonal therapy for breast cancer: validation of an endocrine symptom subscale for the FACT-B.

Existing quality of life instruments do not include adequate items to measure the side effects and putative benefits of hormonal treatments given in breast cancer. We report the development and validation of an 18 item endocrine subscale (ES) to accompany a standardised breast cancer quality of life measure, the Functional Assessment of Cancer Therapy (FACT-B). The FACT-ES (FACT-B plus ES) was tested initially on 268 women with breast cancer receiving endocrine treatments. Alpha coefficients for all subscales demonstrated good internal consistency (range alpha = 0.65-0.87). Test-retest reliability of the ES indicated good stability (r = 0.93, p < 0.001). Advanced breast cancer patients' quality of life was high, showing the efficacy of endocrine therapy, but women with primary disease reported better physical, social, and functional well-being and fewer breast cancer concerns. Most frequently reported symptoms were loss of sexual interest (31%), weight gain (25%), and hot flushes (24%). Significant differences were found between treatment groups for hot flushes and vaginal dryness. Two assessments of the instrument's responsiveness to change were made; 32 women in a clinical trial of endocrine therapy and 18 women without breast cancer taking HRT completed the FACT-ES at baseline, 4, 8, and 12 weeks. Trial patients reported significantly more symptoms at 8 and 12 weeks than at baseline. Women taking HRT reported significantly fewer or less severe symptoms than at baseline. In conclusion the FACT-ES has acceptable validity and reliability and is sensitive to clinically significant change, making it suitable for clinical trials of endocrine therapy.     

Pre-treatment symptom cluster in breast cancer patients is associated with worse sleep, fatigue and depression during chemotherapy

Objective: The concept of symptom clusters is relatively new in cancer patients' symptom management. This study, which spanned four cycles of chemotherapy, combined three commonly seen pre‐treatment symptoms in cancer patients (i.e. sleep disturbances, fatigue and depression) into one symptom cluster, to explore the associations between pre‐treatment cluster categories and longitudinal profiles of these same symptoms during chemotherapy. Methods: This was a prospective study. Seventy‐six women with newly diagnosed stage I–III breast cancer, scheduled to receive at least four cycles of adjuvant or neoadjuvant anthracycline‐based chemotherapy participated. Data were collected at seven time points before and during treatment. Sleep quality was measured with the Pittsburgh Sleep Quality Index. Fatigue was measured with the Multidimensional Fatigue Symptom Inventory—Short Form. Depressive symptoms were measured with the Center of Epidemiological Studies—Depression. Patients were divided into three groups based on the number of symptoms they experienced before the start of chemotherapy (i.e. no symptoms, 1–2 symptoms or all three symptoms) and a symptom cluster index (SCI) was computed. Results: All women reported worse sleep, more fatigue and more depressive symptoms during treatment compared with baseline (all p's<0.01); however, those women with a higher SCI (i.e. more symptoms pre‐treatment) continued to experience worse symptoms during treatment compared with those who began with fewer symptoms (all p's<0.01). Conclusions: A higher clinically relevant‐based pre‐treatment symptom cluster was associated with more sleep disturbances, greater fatigue and more depressive symptoms during chemotherapy. Specific interventions for these pre‐treatment symptoms may improve the frequency and severity of these same symptoms during chemotherapy, when they are most severe and most disruptive to quality of life.

The clinical features,management and prognostic effects of pathological fractures in a multicenter series of 373 patients with diffuse large B-cell lymphoma of the bone

BackgroundPathological fractures (PFs) occur in 10%–20% of patients with diffuse large B-cell lymphoma (DLBCL) of the bone. The clinical features and the effects of this severe complication on management and prognosis have not been previously analyzed in a large series.Patients and methodsThe effects of PF on management and prognosis were reviewed in an international retrospective series of 373 patients with newly diagnosed bone DLBCL, comparing 78 patients with PF at presentation (group ‘PF-BL’) and 295 patients without PF (‘controls’).ResultsAt a median follow-up of 53 months (range 3–246), PF-BL patients exhibited lower rates of overall response (ORR, 78% versus 85%; P = 0.17), 5-year progression-free survival (PFS, 53 ± 6% versus 61 ± 3%; P = 0.02) and 5-year overall survival (OS, 54 ± 6% versus 68 ± 3%, P = 0.008) than controls. Initial surgical stabilization of the PF did not change therapeutic outcome (5-year OS: 45 ± 9% versus 54 ± 10%; P = 0.20). PF-BL patients referred to irradiation of the fractured bone before chemotherapy exhibited a significantly poorer outcome than patients managed with the inverse sequence (ORR: 52% versus 92%, P = 0.0005; 5-year OS: 22 ± 14% versus 64 ± 9%, P = 0.007). Multivariate analysis confirmed the independent association between PF and worse survival and the negative effect of radiotherapy as initial therapy.ConclusionFracture is an independent, adverse prognostic event in patients with bone DLBCL. Anthracycline-based chemotherapy followed by radiotherapy seems to be the better treatment sequence. Initial fracture stabilization does not seem to improve outcome; it should be used to improve patient's quality of life only if chemotherapy delays can be avoided.
