Purpose: Patient nonadherence to oral antineoplastic therapy is a well-recognized barrier to effective treatment. In order to identify patients who may need additional support to become adherent, it is important to have a useful tool that takes into account all the parameters of adherence to prescription. The aim of this prospective study was to evaluate adherence of oral antineoplastic agents and to investigate two calculation methods of adherence score. Patients and Methods: Twenty-nine cancer patients were enrolled in this study. Fourteen were treated by capecitabine and 15 patients by aromatase inhibitors. Adherence was measured using a medication event monitoring system and adherence score was calculated by a usual method and a composite adherence score that takes into account missed doses and also intake interval errors (between 2 doses and between meals). Results: Across the 6-month evaluation period, average adherence was 95% with the standard calculation (capecitabine group: 89%; aromatase inhibitor group: 99%) versus 83% with the composite index (capecitabine group: 62%; aromatase inhibitor group: 99%) (p = 0.030). The composite calculation permits to highlight more nonadherent patients (29.6 vs. 7.4%), particularly in the capecitabine group (73 vs. 18%, p = 0.001). We report 2 cases identified as nonadherent with composite adherence rate. Conclusion: The composite adherence score permits to better evaluate adherence to prescription and to identify barriers to adherence and persistence. Copyright © 2012 S.

Background: Metastatic castration-resistant prostate cancer (mCRPC) patients have a poor prognosis, and curcumin is known to have antineoplastic properties. On the basis of previous phase I and phase II studies, we investigated whether the association of curcumin with docetaxel could improve prognosis among mCRPC patients., Methods: A total of 50 mCRPC patients (included from June 2014 to July 2016) treated with docetaxel in association with oral curcumin (6 g/d for 7 days every 3 weeks) versus placebo were included in this double-blind, randomized, phase II study. The primary endpoint was to evaluate the time to progression. Among the secondary endpoints, compliance, overall survival, prostate-specific antigen (PSA) response, safety, curcumin absorption, and quality of life were investigated. An interim analysis was planned in the modified intention-to-treat population with data at 6 months (22 patients per arm)., Results: Despite good compliance and a verified absorption of curcumin, no difference was shown for our primary endpoint: progression-free survival (PFS) between the placebo and curcumin groups was, respectively, 5.3 months versus 3.7 months, p = 0.75. Similarly, no difference was observed for the secondary objectives: PSA response rate (p = 0.88), overall survival (p = 0.50), and quality of life (p = 0.49 and p = 0.47)., Conclusion: Even though our previous studies and data in the literature seemed to support an association between curcumin and cancer therapies in order to improve patient outcome and prognosis, the results from this interim analysis clearly showed that adding curcumin to mCRPC patients' treatment strategies was not efficacious. The study was discontinued on the grounds of futility., (© 2021 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.)

In breast cancer patients, weight and fat mass changes observed after chemotherapy have been related to poor prognosis but some recent works using modern chemotherapy failed to find this correlation with weight gain. In this study, the extent of changes in weight and body composition (DEXA, impedance) was characterized until six months after current chemotherapy, in 50 post-menopausal women with breast cancer. The evolution of factors contributing to the energy balance and some biological factors were also described. During chemotherapy, 20% of women lost weight due to both fat (-13.1% ± 10.3) and lean soft tissue mass loss (-3.6% ± 4.6). Twenty percent of women gained weight. No significant fat mass gain was observed in these women but significant water gain was highlighted. Six months later, women who gained weight presented a gain in fat mass (15.4% ± 19.0), especially in the abdominal region. Age and initial BMI were negatively correlated with fat mass in multivariate analyzes (r = 0.486, P = 0.0030). No significant variation of the glucose homeostasis, triglycerides, and HDL-Cholesterol was found six months after chemotherapy. These results do not suggest major adverse metabolic disturbances six months after modern chemotherapy and only a mild fat mass gain was observed in women who gained weight.

Background: Weight changes during adjuvant treatment for early-stage breast cancer has been associated with a poor prognosis. The long-term evolution of body composition during adjuvant treatment for breast cancer, in particular, endocrine therapy, is not well known, and new data on this topic are required. The present study assessed the evolution of weight and body composition among 33 postmenopausal breast cancer patients receiving endocrine therapy after standard adjuvant chemotherapy that included taxanes., Patients and Methods: Dual-energy x-ray absorptiometry was used to measure the fat and lean body mass. Body water was assessed using multifrequency bioelectrical impedance analysis. The Hospital Anxiety and Depression questionnaire and the short version of the International Physical Activity Questionnaire were also administered., Results: During endocrine therapy, 5 of the 33 patients (15.2%) lost weight and 12 (36.4%) gained weight. The overall average gain was 2.0 ± 5.5 kg (P = .04). During this period, the fat mass, lean body mass, and body water increased. The factors linked to fat mass gain included an excess fat mass (≥ 36%) before treatment and weight loss during chemotherapy. In the overall period of adjuvant cancer treatment, 30% of the population gained > 5% of their initial weight. The average gain was the same as that during the endocrine therapy period (2.0 ± 5.4 kg; P = .031) and was characterized by an increase in total lean body mass, mainly localized in the trunk region., Conclusion: Endocrine therapy appears as a pivotal period in weight and body composition management. Overfat and obese patients and those who lose weight during chemotherapy were more subject to weight and fat mass gain during endocrine therapy., (Copyright © 2018 Elsevier Inc.

Objectives: Favorable phase I results justified this pilot phase II study to assess the efficacy of docetaxel/curcumin in patients with chemotherapy-naive metastatic castration-resistant prostate cancer (CRPC)., Methods: Thirty patients with progressing CRPC and a rising prostate-specific antigen (PSA) received docetaxel/prednisone in standard conditions for 6 cycles in combination with per os curcumin, 6,000 mg/day (day -4 to day +2 of docetaxel). The co-primary endpoint was the overall response rate determined by PSA and target assessments. An ancillary study assessed the seric values of chromogranin A (CgA) and neuron-specific enolase (NSE)., Results: Twenty-six patients received the scheduled treatment, 2 progressed and 2 died before the end of treatment. A PSA response was observed in 59% of patients (14% of PSA normalization) and achieved within the first three cycles for 88% of responders. Partial response was reached for 40% of evaluable patients. The regimen was well tolerated, and no adverse event was attributed to curcumin. Twenty patients were 100% curcumin compliant. The PSA level and objective response rate were not correlated with the serum values of CgA and NSE., Conclusion: This study produced additional data on curcumin as a treatment for cancer, with a high response rate, good tolerability and patient acceptability, justifying the interest to conduct a randomized trial., (© 2016 S.

Background: Everolimus (Afinitor®) plus exemestane are indicated for hormone receptor-positive, HER2/neu-negative metastatic breast cancer (MBC), in menopausal women without symptomatic visceral disease after recurrence or progression following aromatase inhibitors. But everolimus efficacy as late treatment has not been explored., Methods: Sixty-three MBC patients progressing under hormonotherapy (HT; n = 30) or after chemotherapy (CT; n = 32) received everolimus plus HT (EHT) and were analyzed for safety, efficacy and overall survival (OS). This cohort was compared with our previous 530 MBC patients stratified by line (PMID 21852136)., Results: The median duration of EHT was 27.8 weeks at 5-10 mg/day until clinical progression or toxicity. Median OS was not reached (median follow-up 18 months). Twelve-month survival was 100, 79 and 49% for patients treated with 0 (n = 13), 1-2 (n = 18) and >3 CT (n = 32), respectively. Median time-to-treatment failure was 6.4 months. In 62 EHT patients randomly matched 1:7 with 421 previous patients for age and number of CT, OS improved compared with patients receiving a new CT (p = 0.062). In patients pretreated with <2 CT, EHT gave a better OS than in those with a new CT (p = 0.026)., Conclusions: These results may support the use of EHT whatever the number of previous lines., (© 2015 S.

Background: Geriatric Assessment is an appropriate method for identifying older cancer patients at risk of life-threatening events during therapy. Yet, it is underused in practice, mainly because it is time- and resource-consuming. This study aims to identify the best screening tool to identify older cancer patients requiring geriatric assessment by comparing the performance of two short assessment tools the G8 and the Vulnerable Elders Survey (VES-13)., Patients and Methods: The diagnostic accuracy of the G8 and the (VES-13) were evaluated in a prospective cohort study of 1674 cancer patients accrued before treatment in 23 health care facilities. 1435 were eligible and evaluable. Outcome measures were multidimensional geriatric assessment (MGA), sensitivity (primary), specificity, negative and positive predictive values and likelihood ratios of the G8 and VES-13, and predictive factors of 1-year survival rate., Results: Patient median age was 78.2 years (70-98) with a majority of females (69.8%), various types of cancer including 53.9% breast, and 75.8% Performance Status 0-1. Impaired MGA, G8, and VES-13 were 80.2%, 68.4%, and 60.2%, respectively. Mean time to complete G8 or VES-13 was about five minutes. Reproducibility of the two questionnaires was good. G8 appeared more sensitive (76.5% versus 68.7%, P =  0.0046) whereas VES-13 was more specific (74.3% versus 64.4%, P<0.0001). Abnormal G8 score (HR = 2.72), advanced stage (HR = 3.30), male sex (HR = 2.69) and poor Performance Status (HR = 3.28) were independent prognostic factors of 1-year survival., Conclusion: With good sensitivity and independent prognostic value on 1-year survival, the G8 questionnaire is currently one of the best screening tools available to identify older cancer patients requiring geriatric assessment, and we believe it should be implemented broadly in daily practice. Continuous research efforts should be pursued to refine the selection process of older cancer patients before potentially life-threatening therapy.

The hormonal therapy of patients with endocrine-sensitive early breast cancer has mainly consisted, for several decades, of the gold standard tamoxifen. The efficacy and favorable toxicity profiles of third-generation aromatase inhibitors (AIs), anastrozole, letrozole and exemestane, in advanced disease led to their development in early breast cancer. Recent results consistently show the superiority of these agents over tamoxifen. Adjuvant trials evaluated AIs using four different therapeutic approaches: (1) Upfront strategy: randomization of newly diagnosed patients: tamoxifen for 5 years versus AI for 5 years. (2) Sequencial strategy: randomization of newly diagnosed patients: tamoxifen (2 - 3 years) followed by AI or the inverse for a total of 5 years versus upfront AI for 5 years. (3) Switch strategy: delayed randomization (or analysis) after 2 - 3 years of tamoxifen (patients free of disease): 2 - 3 years of tamoxifen versus 2 - 3 years of AI (total treatment 5 years). (4) Extended strategy: delayed randomization after 5 years of tamoxifen (patients free of disease): 2 - 5 years of AI versus placebo. Overall, AIs show evidence of superiority over tamoxifen in the adjuvant setting with proven improved efficacy and better toxicity profile. Despite some common characteristics, a body of evidence on AIs indicates some specific differences between the three agents in mechanism of action, pharmacokinetics, efficacy as well as toxicity profiles. Consequently, these hormonal agents may not be considered interchangeable in clinical practice. This review explores available results from AI trials and tries to define their present role in the adjuvant management of postmenopausal patients with breast cancer.

Neoadjuvant chemotherapy in breast cancer corresponds to the use of a systemic treatment applied before loco-regional treatment (surgery and/or radiotherapy). Initiated in the seventies for treatment of the locally advanced and/or inflammatory breast cancers, induction chemotherapy has been extended in the beginning of eighties for cancers known as operable (size higher than 3 cm and/or in central position) in order to allow a more frequent conservating surgery. This objective is obtained in 75% of the cases approximately without increase in the risk of local relapse and without noxious effect on overall survival, in spite of the delay of the loco-regional treatment. Neo-adjuvant chemotherapy progressively moved with the advent of major drugs in breast cancer which are anthracyclins, vinorelbine and taxans. But to date, no protocol was essential like an uncontested standard. However, it seems that obtaining a complete clinical response is the best guarantor to avoid relapse. That seems to be observed only after 6 cycles, even 8 cycles of chemotherapy, each cycle combining the 2 major drugs for the treatment of breast cancer of which are anthracyclins and taxanes employed according a sequential scheme after a based-anthracyclins treatment, except any cardiac contra-indication. Moreover, the use of targeted therapeuticals like Herceptin, with a chemotherapy, seems to be promising and should be more studied. Finally, when a neoadjuvant chemotherapy is administered, the evaluation of the pre-treatment biopsy helps to establish key patient-management parameters such as tumour type, SBR grade and immunohistochemical parameters. This evaluation provides predictive parameters with regards to drug response (hormonal status, overexpression of Her2). The further studies realised in this way will permit to improve the results yet obtained.

This phase II study investigated the efficacy and tolerability of a primary chemotherapy regimen combining vinorelbine, epirubicin, and paclitaxel (VEP protocol) in women with stage II/III operable breast cancer. Patients (n = 50) were treated with six cycles of VEP according to the following schedule: vinorelbine (Navelbine); Pierre Fabre, Boulogne, France; http://www.pierre-fabre.com) 20 mg/m2, epirubicin (Farmorubicin; Pharmacia, New York, NY; http://www.pnu.com) 35 mg/m2 given on days 1 and 8, paclitaxel (Taxol; Bristol-Myers Squibb, New York, NY; http://www.bmsoncology.com) 175 mg/m2 given on day 9, and G-CSF 5 mg/kg/day given on days 10-20 of a 21-day cycle, followed by surgery and radiotherapy. After six cycles of VEP, the pathological response rate (pCR) in breast was confirmed in six patients (12%; 95% confidence interval [CI]: 3-21)) using Chevallier's classification and in nine patients (18%; 95% CI: 7.4-28.6) using Sataloff's classification. The clinical response rate was 42% (95% CI: 28.3-55.7), including 26% complete responses. Breast conservation was achieved in 68% of patients. After a median follow-up of 48 months (range, 34-62 months), 16 relapses were observed. The overall and disease-free survivals at 5 years were 54.1% (95% CI: 40.3-67.9) and 38% (95% CI: 24.1-51.9), respectively. The principal toxicities of VEP were grade 3/4 neutropenia observed in 30% of patients and grade 3 anemia observed in 12% of patients. There was no case of severe cardiac toxicity, thrombocytopenia, or any other serious adverse events. In conclusion, whereas this regimen was relatively well tolerated, it appears inferior to other regimens and its use is not recommended.

Purpose: To assess whether an epirubicin (EPI) -based chemotherapy plus hormonal regimen improves disease-free (DFS) in women older than 65 years, with node-positive, operable breast cancer (BC), relative to tamoxifen (TAM) alone., Patients and Methods: A total of 338 patients were randomly assigned after surgery to receive TAM 30 mg/d for 3 years (TAM, n = 164), or EPI 30 mg on days 1, 8, and 15 every 28 days for six cycles plus TAM 30 mg/d for 3 years (EPI-TAM, n = 174). In both arms, patients received radiotherapy, delivered after chemotherapy (CT) in the EPI-TAM group., Results: The 6-year DFS rates were 69.3% with TAM and 72.6% with EPI-TAM (P = .14). The multivariate analysis shows a relative risk of relapse of 1.93 (95% CI, 1.70 to 2.17) with TAM compared with EPI-TAM (P = .005). The 6-year OS, related to disease progression, was 79.1% and 79.8%, respectively (P = .41). Compliance with CT was good: 96.9% of patients received six cycles. The acute toxicity per patient was mild: grade 2 neutropenia in 5.9%, grade 2 anemia in 2.0%, grade 3 nausea or vomiting in 4.6%, and grade 3 alopecia in 7.2%. Five cases (in five patients) of decreased left ventricular ejection fraction occurred after CT: three after adjuvant CT, and two after anthracycline-based CT for relapse. One patient died as a result of dysrhythmia related to carcinomatous lymphangitis. No secondary leukemia occurred., Conclusion: This study conducted in node-positive elderly patients demonstrates a significant contribution of a weekly EPI regimen in terms of DFS. Moreover, this regimen is safe for hematologic, nonhematologic, and cardiac toxicities.

PURPOSE To evaluate long-term cardiac function in patients without disease who had received six cycles of fluorouracil 500 mg/m(2), epirubicin 50 mg/m(2), and cyclophosphamide 500 mg/m(2) (FEC 50) or the same regimen with epirubicin 100 mg/m(2) (FEC 100) as adjuvant chemotherapy for node-positive breast cancer in the French Adjuvant Study Group-05 trial. PATIENTS AND METHODS One hundred fifty patients (FEC 50, n = 65; FEC 100, n = 85) who were without disease and who gave their informed consent were enrolled for long-term cardiac assessment. The assessment included cardiac events occurring after the end of chemotherapy, vital signs, concomitant disease, ECG, isotopic left ventricular ejection fraction (LVEF), and echographic parameters. Abnormal files were blindly reviewed by cardiologists and oncologists. Results The median follow-up time was 102 months. After FEC 100, LVEF was less than 50% in five patients (radioisotopic method), and two patients experienced congestive heart failure (CHF) that was possibly related to treatment. Asymptomatic left ventricular dysfunction (LVD) was experienced in 18 patients after FEC 100 and in one patient after FEC 50. In these patients, treatment causality was probable in eight patients. Two additional years after this assessment, all 18 patients were still asymptomatic. CONCLUSION After more than 8 years of follow-up, the cardiac toxicity observed after adjuvant treatment with FEC 100 comprised two cases of well-controlled CHF and 18 cases of asymptomatic LVD. In the majority of women with primary breast cancer, the benefits of treatment with FEC 100 in terms of disease-free and overall survival outweigh the risks, and cardiac risk factors should be carefully evaluated in patient selection., (Copyright 2004 American Society of Clinical Onocology)

Various alterations of aminoacidemia have been described during breast cancer. The aim of this study was first to establish the specific modifications of plasma-free amino acid concentrations by a comparative study of 19 patients with mammary tumors and 18 healthy volunteers, and, second, to determine the evolution of aminoacidemia after surgical tumor removal. Aminoacidemia was determined the day before (D0), and then five days, one month (M1), and six months after surgical removal of the tumor, and a single determination was performed in control subjects. Plasma levels (mumol/L) of serine and glutamate were higher in cancer-bearing women at D0 (respectively, 124 +/- 3 and 68 +/- 7) than in healthy volunteers (respectively, 110 +/- 6 and 48 +/- 5). Surgical tumor removal induced a normalization of aminoacidemia (in mumol/L at D5: serine: 114 +/- 4; at M1: glutamate: 55 +/- 6 Non Significant (NS) from values of healthy subjects). Among the various patterns reported for breast cancer, we confirm one of those described by Cascino in 1995, and we show that these levels revert to normal after tumor surgical removal.

Purpose: In order to improve the breast conservation rate for noninflammatory operable breast cancer stage II and IIIa, neoadjuvant chemotherapy containing vinorelbine, 25 mg/m(2), epirubicin, 35 mg/m(2), and methotrexate, 20 mg/m(2), VEM, was administered days 1 and 8 every 28 days for six cycles., Methods: From October, 1991 to April, 1996, 89 patients (median age 52 years, range 31-72; 68 stage II and 19 stage IIIa) received 519 cycles (median six) of VEM chemotherapy., Results: Hematotoxicity was mild (World Health Organization grade 3-4 neutropenia in 28% of cycles for 22 patients, and anemia or thrombocytopenia >grade 2) when it occurred, and there were no toxic deaths. The clinical objective response was 90% (28% complete response and 62% partial response). All patients underwent surgery: 77 (87%) had conservative and 12 (13%) had modified radical mastectomy, and 12 (14%) reached pathological complete response. At December, 2000, with a median follow-up of 86 months (39-100), 13 patients had relapsed, and five had died of metastatic disease. Median disease-free survival was 100 months (8.4 years) and median survival had not yet been reached.

Fetal anomalies were suspected clinically in 3 patients, during the second trimester of pregnancy, due to advanced maternal age, hydramnios and abnormal vaginal bleeding respectively. Sonography revealed anencephaly in all of them, confirmed by roentgenograms and also by high amniotic fluid leveal alpha-fetoprotein in 1 of them. The antenatal diagnosis was confirmed in the 3 abortuses. Early screening of all pregnancies at risk for neural tube malformations is strongly recommended.

The efficacy and safety of paracervical block anesthesia were studied in 153 patients in the first stage of labour. Transient decrease in uterine activity was noted in 77 patients. There was no acceleration in cervical dilatation following the block. The duration of action of the block in 80 primiparas was 31 to 120 minutes in 69, and over 120 minutes in five. In the 73 multiparas, 53 of the blocks lasted 31 to 90 minutes, eight from 90 to 120 minutes, and two over 120 minutes. The results were good in 66 primiparas and 54 multiparas. The blocks failed in four primiparas and six multiparas. Twenty-six infants had low Apgar scores, but in none could this be related to the paracervical block. There were no significant fetal or maternal complications.

Paracervical block anesthesia was used for dilatation and curettage in 37 patients in situations where general anesthesia or sophisticated forms of conduction anesthesia were either unavailable or contraindicated. Ten millilitres of either 1% xylocaine or procaine or 5 ml. of 2% xylocaine was placed into each lateral fornix with a standard 6-inch, 20-gauge needle at a depth of six to 12 millimetres. The block's effect was good in 34 cases and fair in three; there were no failures. No significant complications occurred. The necessity of guarding against and/or being prepared to treat local anesthetic sensitivity is recognized. Paracervical block proved to be a convenient, safe, simple and effective anesthetic technique for dilatation and curettage, including when other anesthetic techniques were contraindicated.
