RESUMEN

Although a cure still cannot be expected for metastatic breast cancer, thanks to progressive advances in treatments, life expectancy has been increasing over the past 15 years. This study aims to present the impact on the organisation of patients' management of newly released oral targeted therapies dedicated to metastatic breast cancer and the obstacles to their diffusion. Our work is based on the analysis of 40 semi-structured interviews, conducted with oncology healthcare professionals in three regions of France (2015-2016). It shows three main results. First, the prescription of an oral targeted therapy requires greater collaboration between healthcare professionals than traditional intravenous oncology drugs, which may be challenging. Second, there remain many barriers to the dissemination of oral targeted therapies. Third, taking an oral targeted therapy keeps the patient away from the hospital facility and asks for a strong therapeutic alliance. The management of oral targeted therapies is time-consuming for medical oncologists and disrupts the traditional care pathway. The multiplication of actors involved in patients' management reinforces the slowdown in the deployment and acceptance of therapeutic innovations. More players equal a higher risk of slowdown. Questioning and re-designing hospital organisation and management modalities towards this type of care are critical.

RESUMEN

The systematic use of patient-reported measures (PRMs) [i.e., patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs)] is advocated as an effective way to improve care practices. However, whether PRMs can lead to the performance assessment of healthcare organisations (HCOs) through valid quality indicators (QIs) for national purposes (i.e., public reporting and paying for performance) is open to debate. This study undertakes a scoping review to examine the use of PRMs as QIs for health policy purposes and to identify the challenges faced in the emblematic case of oncology. According to PRISMA guidelines, published papers, websites and reports published by national and international initiatives were analysed using five online databases (Web of Science, Scopus, PubMed, JSTOR and Google Advanced Search), and then studied using the same keywords. We selected 61 articles and 19 websites/reports and identified 29 PREMs and 48 PROMs from 14 countries and two international initiatives that routinely used them as QIs for HCOs' comparisons. Four types of barriers to this specific use were identified relating to the definition of a standard set, scientific soundness, data collection, and the actionability of such measures. Despite current developments, different barriers still must be overcome before PRMs can be used for health policy purposes in oncology. Future research is needed to ensure that valid QIs related to PRMs are applied at a national level.

RESUMEN

BACKGROUND: A number of anaemic cancer patients are not responsive to treatment with recombinant human erythropoietin (rHuEPO). The aim of the present study is to investigate whether serum levels of tumour necrosis factor-alpha (TNF-alpha), interleukin (IL)-1beta, IL-6 and additional laboratory parameters, together with clinical variables, can predict the clinical outcome of treatment with rHuEPO in anaemic cancer patients. PATIENTS AND METHODS: Thirty-five cancer patients and 25 healthy controls were enrolled in this study. Patients were treated with epoetin alfa at the dose of 150 IU/kg s.c. three times a week for 12 weeks. If the haemoglobin (Hb) level failed to improve at least 2 g/dl above baseline by week 6 of treatment, dose was increased to 300 IU/kg s.c. for the remainder of the treatment period. All patients filled out the Brief Fatigue Inventory (BFI), a questionnaire for the self-evaluation of cancer-related fatigue. Serum samples from patients and control groups were frozen at -80 degrees C and TNF-alpha, IL-1beta and IL-6 were later examined by enzyme-linked immunosorbent assay. RESULTS: Fatigued cancer patients had significant higher levels of circulating TNF-alpha, IL-1beta and IL-6 than healthy controls. Responders (Rs) to erythropoietin had significant lower medium levels of TNF-alpha and IL-6 than nonresponders (NRs). Fatigued patients with a general BFI score > or =6 presented higher medium level of cytokines than nonfatigued patients (general BFI score <6), but each group responded similarly to treatment with rHuEPO. CONCLUSIONS: High serum levels of TNF-alpha and IL-6 at the baseline are significantly correlated with a negative response to administration with rHuEPO. Thus, pretreatment evaluation of TNF-alpha and IL-6 serum levels can help to select those patients who are most likely to benefit from treatment with rHuEPO. On the contrary, Hb level, red blood cell count, lactate dehydrogenase and BFI score do not predict the outcome of treatment with rHuEPO.

RESUMEN

BACKGROUND: In patients with bone metastases from castration-resistant prostate cancer (CRPC) not pretreated with a bisphosphonate elevated N-telopeptide of type I collagen (uNTx), a marker of bone resorption, predicts skeletal-related events (SRE). The aim of this study was to assess the prognostic value of uNTx for overall survival (OS) and the incidence of SRE in patients with bone metastases from CRPC receiving zoledronic acid. METHODS: From 2004 to 2007, 94 patients with bone metastases from CRPC receiving zoledronic acid for at least 2 months were screened for uNTx. RESULTS: Median age was 66 years (range 46-88). Median serum prostate-specific antigen (PSA) was 66 ng/ml (0-3984) and median uNTx was 19 nmol/mM creatinine (3-489). During follow-up, 38 patients (40%) experienced an SRE. Median OS was 20 months [95% (CI) confidence interval 15-24). In the multivariate analysis, elevated uNTx [hazard ratio (HR) 2.2 (95% CI 1.2-4.0)], serum PSA [HR 2.8 (95% CI 1.6-5.1)], and ECOG performance status were the only independent prognostic factors for OS. Median OS was 12 months (10-16) and 25 months (21-34) in patients with uNTx > or =20 nmol/mM creatinine and in those with uNTx <20 nmol/mM creatinine, respectively. CONCLUSION: An elevated uNTx level is an independent prognostic factor for OS in patients with bone metastases from CRPC receiving a bisphosphonate.

RESUMEN

INTRODUCTION: The aim of this study was to evaluate the quality of the MR compilation in some Operative Units of the "Azienda Ospedaliera Universitaria--II Università di Napoli" (AOU- SUN)-Italy, before and after an intervention of quality improvement, underlining the potential differences in the behaviour of different specialists (physicians vs. surgeons). METHODS: Two random samples of 660 MRs were reviewed. A four-step program was developed: (1) first assessment of the MR; (2) implementation of the MR quality, sending a letter with the purpose of the study, the results obtained in the first step from that ward, the guidelines to correctly fill out the MR; (3) follow-up step four months later; (4) comparison of the data before and after the distribution of the guidelines using indicators of completeness of all sections of MR, clarity of handwriting and presence and clarity of signature. RESULTS: The main concerns were related to the signature of the duty physician (present in 2.0% and legible in only 15.4%), the presence of the letter of discharge (18.0%) and the clarity of the days of hospital stay (32.0%). After the intervention the improvement of the quality of compilation was modest and regarded mainly medical rather than surgical wards. DISCUSSION AND CONCLUSIONS: The improvement was not satisfying since from a medical and a legal point of view the indicators should reach 100% of clarity and completeness. A further study is being carried out to improve the involvement of health care professional, so that such requirements will be perceived as a common goal, not as mere bureaucratic initiatives.

RESUMEN

BACKGROUND: There is currently no standard treatment for patients with castration-resistant prostate cancer (CRPC) whose disease progresses after docetaxel-based chemotherapy. The purpose of this study was to prospectively assess the anticancer activity and tolerance of the carboplatin-etoposide combination in this setting while evaluating neuroendocrine (NE) features. PATIENTS AND METHODS: Patients with CRPC and metastases who experienced failure after first-line docetaxel-based chemotherapy were treated with carboplatin (area under the curve 5, day 1) and etoposide (80 mg/m(2)/day from days 1 to 3), repeated every 3 weeks. The association between serum chromogranin A (CgA), neuron-specific enolase (NSE), prostate-specific antigen-doubling time (PSADT), and treatment efficacy was studied. RESULTS: Forty patients with CRPC who had received docetaxel with (n = 20) or without (n = 20) estramustine received the carboplatin-etoposide combination as second-line chemotherapy. A prostate-specific antigen (PSA) response defined as a PSA decline > or =50% was achieved in nine patients (23%). Median progression-free survival (PFS) was 2.1 months (range 0.6-9.6) and median overall survival was 19 months (range 2.1-27.7). Pain response was achieved in 15 (53%) of 28 assessable patients. Toxicity, including mainly grades 3-4 anaemia (25%) and febrile neutropenia in only 2% of patients, was manageable. Baseline CgA, NSE, or PSADT were not significant predictors for response or PFS. The PSA response rates were 18% and 31% in patients with normal and elevated serum CgA, respectively. It was 25% and 20%, respectively, in patients with normal and elevated serum NSE. CONCLUSIONS: Combining carboplatin and etoposide as second-line chemotherapy in patients with CRPC is active and well tolerated in spite of a limited PFS. Activity was observed in CRPC with and without NE features.

RESUMEN

In this study, we explored vagally-mediated heart rate variability (vmHRV) responses, a psychophysiological index of cognitive self-regulatory control, to map the dynamics associated with empathic responses for pain towards an out-group member. Accordingly, Caucasian participants were asked to judge the experience of African and Caucasian actors touched with either a neutral or a harmful stimulus. Results showed that (1) explicit judgment of pain intensity in African actors yielded higher rating score and (2) took longer time compared to Caucasian actors, (3) these behavioural outcomes were associated with a significant increment of RMSSD, Log-HF-HRV and HF-HRV n.u., (4) resting HF-HRV n.u. predicted the participants' lag-time to judge painful stimulations delivered to African actors. Interestingly, these dynamics were associated with a measure of implicit racial attitudes and were, in part, abolished when participants performed a concurrent task during videos presentation. Taken together our results support the idea that a cognitive effort is needed to self-regulate our implicit attitude as predicted by the 'Contrasting Forces Model'.

RESUMEN

BACKGROUND: Chemotherapy has emerged as a standard treatment in patients with castration-refractory prostate cancer (CRPC). Consensus criteria are available to define response in CRPC as at least a 50% decline in serum prostate-specific antigen (PSA) confirmed 4 weeks later. The objective of this work was to study early serum PSA changes in patients under chemotherapy and to correlate these changes with subsequent response assessment. PATIENTS AND METHODS: Serum PSA levels were monitored every 3 weeks in 79 patients with CRPC treated with chemotherapy and a time course of serum PSA levels was obtained. Correlation with response was studied. RESULTS: According to consensus criteria, 21 (40%) and 20 (38%) patients achieved a PSA response and stabilization, respectively, after first-line chemotherapy. Among patients who achieved either a response or a stabilization, 8 of 41 (20%) had a serum PSA rise during the first 8 weeks of chemotherapy, followed by a subsequent decline in serum PSA. The same observation was made in patients receiving second-line chemotherapy: 6 of 20 patients achieving a response or stabilization had an initial serum PSA rise. The postchemotherapy increase in serum PSA could reach more than twice the baseline value. The duration of the PSA surge ranged from 1 to 8 weeks. When considering responders only, 6 of 30 (20%) had a postchemotherapy serum PSA surge, followed by a drop. CONCLUSION: Postchemotherapy PSA surges occur not infrequently in patients with CRPC who respond to chemotherapy. Physicians should be aware of this effect to avoid inadequate early discontinuation of chemotherapy.

RESUMEN

To evaluate and improve the quality of medical-record keeping, in clinics and surgery departments. The evaluation involved 66 Operative Units (O.U.) of the "2nd University Hospital" in Naples (Italy). 10 medical records for each O.U. were randomly selected, for a total of 660. The quality was evaluated in all sections of medical records using the criteria of completeness, clarity and traceability of the data. The most critical issues are: unclear handwriting in almost all sections, in the whole scarse presence of a discharge letter (17.0%) in surgery (1.4%), almost total absence of the physicians signature in the clinical diary (2.3%). The completeness of medical records (presence of patient's history, physical examination, informed consent) is significantly higher in the surgery departments. The medical records are significantly righter in the clinic departments. In general, a poor quality of medical-record keeping was detected. This indicates the need to improve the quality by involving the staff in the importance of correct compilation.

RESUMEN

Supportive cancer care is defined as "all the care and support necessary for the patient throughout the illness together with specific oncological treatment". This includes side effect treatments, advice to facilitate access to all therapeutic approaches (i. e. home care) and to keep the patient in the social community. Acute pain centers and palliative care units are at the core of this new approach. In urology, the example of patients with bone metastasis demonstrates the usefulness of this concept. In fact it participates in: antalgic treatment, prevention of bone events (bisphosphonates), adaptation of daily life with a handicap, access to physiotherapy, psychological help. It also includes financial allowances. In France, supportive care centers are being set up in most hospital to facilitate the coordination of all the multidisciplinary teams.

RESUMEN

Adult living donor liver transplantation (ALDLT) is an accepted procedure to overcome the organ shortage. The advantages of ALDLT must be balanced against the first concern of donor safety. We analyzed the results of our early experience among a series of eight ALDLT performed between April 2001 and October 2003. All patients were listed as United Network for Organ Sharing UNOS status 2b and 3. Transplant recipients consisted of four men and four women. The living donors included four sons, three daughters, and one son-in-law (ages 20 to 45 years). One donor was anti-HBc-positive and negative for hepatitis B virus-DNA by polymerase chain reaction analysis in serum and in liver tissue. GR/WR >0.8 and fatty liver <10% were considered suitable for the hepatectomy. Residual left lobe volume was at least 33%. No exogenous blood and blood products were transfused into the donors and a cell-saver device was used in all donors (blood loss 490 +/- 160 mL). All procedures were right lobe hepatectomy; in one case the middle hepatic vein was withdrawn with the right graft. The mean ischemia time was 1.5 +/- 0.5 hours. All donors survived the procedure. Median hospital stay was 8.5 +/- 2.1 days in all donors but one who had a long stay because of drug-related hepatitis. One graft was lost and one donor aborted because of preoperative overestimated volumetry. Complications were experienced by two donors (25%). Five recipients (62.5%) experienced major complications; one patient underwent retransplantation because of donor graft loss. Two biliary and two vascular complications (33.3%) occurred in three patients. No perioperative death occurred. Two patients died at 9 and 10 months after transplant because of heart and respiratory failure in the first case and tumor recurrence in the second. One-year actuarial survival is 75%. ALDLT using right lobe has gained acceptance to overcome the organ shortage. Donor selection criteria must be stringent with respect to residual donor hepatic volume, steatosis, and liver function.

RESUMEN

BACKGROUND: The Glu167Lys (E167K) transmembrane 6 superfamily member 2 (TM6SF2) variant has been associated with liver steatosis, high alanine transaminase (ALT) levels and reduced plasma levels of liver-derived triglyceride-rich lipoproteins. OBJECTIVES: The objectives of this study were to investigate in a group of obese children the association among the 167K allele of TM6SF2 gene and ALT, cholesterol and triglycerides levels, and hepatic steatosis, and to evaluate the potential interaction between this variant and the I148M patatin like phospholipase 3 gene (PNPLA3) polymorphism on liver enzymes. METHODS: We genotyped 1010 obese children for TM6SF2 E167K and PNPLA3 I148M polymorphisms. Anthropometrical and biochemical data were collected. Ultrasound imaging of the liver was performed. RESULTS: The 167K allele showed an association with steatosis (P < 0.0001), higher ALT levels (P < 0.001) and lower total cholesterol (P < 0.00001), low-density lipoprotein cholesterol (P < 0.0001), triglycerides (P = 0.02) and non-high-density lipoprotein cholesterol levels (P < 0.000001). The subjects homozygous for the PNPLA3 148M allele carrying the rare variant of TM6SF2 showed an odds ratio of 12.2 (confidence interval 3.8-39.6, P = 0.000001) to present hypertransaminasaemia compared with the remaining patients. CONCLUSION: Although the TMS6SF2 E167K variant predisposes the obese children to non-alcoholic fatty liver disease, there is an association between this variant and lower levels of cardiovascular risk factors. Overall, the data suggest differential effects of TMS6SF2 E167K variant on liver and heart health.

RESUMEN

Creatine supplementation has been shown to protect neurons from oxidative damage due to its antioxidant and ergogenic functions. These features have led to the hypothesis of creatine supplementation use during pregnancy as prophylactic treatment to prevent CNS damage, such as hypoxic-ischemic encephalopathy. Unfortunately, very little is known on the effects of creatine supplementation during neuron differentiation, while in vitro studies revealed an influence on neuron excitability, leaving the possibility of creatine supplementation during the CNS development an open question. Using a multiple approach, we studied the hippocampal neuron morphological and functional development in neonatal rats born by dams supplemented with 1% creatine in drinking water during pregnancy. CA1 pyramidal neurons of supplemented newborn rats showed enhanced dendritic tree development, increased LTP maintenance, larger evoked-synaptic responses, and higher intrinsic excitability in comparison to controls. Moreover, a faster repolarizing phase of action potential with the appearance of a hyperpolarization were recorded in neurons of the creatine-treated group. Consistently, CA1 neurons of creatine exposed pups exhibited a higher maximum firing frequency than controls. In summary, we found that creatine supplementation during pregnancy positively affects morphological and electrophysiological development of CA1 neurons in offspring rats, increasing neuronal excitability. Altogether, these findings emphasize the need to evaluate the benefits and the safety of maternal intake of creatine in humans.

RESUMEN

PURPOSE: To determine the long-term impact on disease-free survival (DFS) and overall survival (OS) of adjuvant anthracycline-based chemotherapy, when prospectively compared by random allocation with standard cyclophosphamide, methotrexate, and fluorouracil (CMF) in node-positive (N+) breast cancer patients. PATIENTS AND METHODS: Two hundred forty-nine patients with N+ breast cancer, recruited from eight French cancer centers, were randomized to receive 12 monthly cycles of adjuvant chemotherapy, either CMF (n = 112) or doxorubicin, vincristine, cyclophosphamide, and fluorouracil (AVCF) (n = 136). All had a negative metastatic work-up before inclusion, which was stratified by accrual center, tumor stage (International Union Against Cancer [UICC]), and menopausal status. RESULTS: No severe adverse effect related to grade 4 (World Health Organization [WHO]) toxicity was observed. There was no difference in second primary tumor incidence between the two arms. The treatment given was 88% of planned for AVCF and 75% for CMF in both premenopausal and menopausal patients. With a median follow-up time of 16 years (range, 13 to 17), the OS and DFS rates are significantly longer in the AVCF arm (56% v 41% [P = .01] for OS, and 53% v 36% [P = .006] for DFS). These differences are significant, irrespective of tumor stage (T1 to T2 v T3 to T4), and remain positive in patients with or without postoperative locoregional radiotherapy (55% of cohort). When analyzed according to menopausal status, the differences remain significant only for premenopausal patients. CONCLUSION: This set of mature controlled data confirms the added value of anthracycline-based combination adjuvant therapy for N+ breast cancer patients when compared with CMF, with both regimens given for 1 year.

RESUMEN

PURPOSE: We report the results of the Subcutaneous Administration Propeukin Program (SCAPP) II trial of an outpatient treatment in renal cell carcinoma using interleukin-2 (IL-2) and interferon alfa-2a (IFN-alpha) administered subcutaneously in combination with fluorouracil (5-FU). The objective of this multicenter trial was to confirm that the combination of IL-2, IFN-alpha, and 5-FU leads to a response rate greater than 20%. PATIENTS AND METHODS: Patients with metastatic renal cell carcinoma were included in this study. During the induction phase of the treatment, which lasted 10 weeks, IL-2 and IFN-alpha were administered subcutaneously three times a week for 8 weeks at doses of 18 MIU and 9 MIU, respectively. During these 8 weeks, every Monday, 5-FU was administered at a dose of 750 mg by intravenous infusion over 30 minutes. After evaluation, responding patients or patients with stable disease (SD) were given maintenance treatment, until disease progression (PD) or the appearance of unacceptable toxicity. Each maintenance cycle consisted of a 2-week treatment followed by a three-week rest period. During treatment, IL-2 and IFN-alpha were administered subcutaneously three times a week at doses of 18 MIU and 9 MIU, respectively. Every Monday, 5-FU was administered at a dose of 750 mg by intravenous infusion over 30 minutes. RESULTS: This trial was closed when the sixth sequential analysis showed the lack of benefit from this combination. At the end of the induction period, of 62 patients, 12 (19%; 95% confidence interval [CI], 10% to 31%) reached an objective response, including one complete response (CR), 16 presented with SD, and 27 showed PD. Twenty-seven patients (43%) developed severe toxicity that required reduction of the planned doses (13 patients), delayed treatment (eight patients), or treatment termination (six patients). Seventeen patients were given maintenance treatment. One- and 2-year survival rates were estimated at 55% and 33%, respectively. The 2-year survival rate was 15% in 11 patients who presented with three poor-prognosis factors and 41% in 51 patients who initially presented with no, one, or two poor-prognosis factors (P = .04). CONCLUSION: As in other recently published studies that used 5-FU, IL-2, and IFN-alpha, the multicenter SCAPP II trial in patients with metastatic renal cell carcinoma generated severe toxicity. This sequential trial failed to confirm the favorable results previously obtained by Atzpodien and Sella with this combination of three drugs. Its efficacy, assessed on the response and survival rates, is near to the results observed in programs that used IL-2 alone given subcutaneously.

RESUMEN

The toxicity and/or the stimulation of natural killer cell activity that resulted from exposure to alpha-interferon varied according to circadian dosing time, both in mice and in human beings. Ten patients with advanced renal cell carcinoma or melanoma were treated with recombinant alpha-interferon-2b using a continuous 21-day intravenous schedule at circadian modulated rate. Patients received 15-20 MU/m2/day in an ambulatory care program. The drug was delivered via an external programmable-in-time pump. Thirty-nine courses of therapy were given (2-12 courses per patient). Severe side effects included World Health Organization grade III somnolence (one patient, 1 course) and grade III-IV neutropenia (five patients, 10 courses). Karnofsky performance status decreased by 40% in 3 patients (five courses). Two of these patients were withdrawn from the study because of toxicity. Disease was stabilized in four of the seven patients evaluable for response. Seven of the 10 patients are alive at 15 months' median follow-up. Two have continued with chronotherapy for 9+ and 13+ months, respectively. A large interpatient variability characterized the maximally tolerated dose. Two patients led their usual activities while receiving 20 MU/m2/day for three courses or more. Conversely, two patients exhibited severe side effects with 10 MU/m2/day. As compared with schedules of standard administration or continuous flat infusion, this circadian schedule of infusion allowed a large increment in total daily dose and dose intensity. A starting dose of 15 MU/m2/day was well tolerated by 8 of 10 patients and can be recommended using this circadian modulated schedule.

RESUMEN

Experimental models have demonstrated the Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH)-potentiating activity of lonidamine. Phase II clinical trials on advanced breast cancer have shown that this drug induced a 16% objective response rate. Present multicentric randomized trial was conducted to verify whether lonidamine can potentiate the antineoplastic effects of conventional fluorouacil, Adriamycin, cyclophosphamide (FAC) chemotherapy in advanced breast cancer. From January 1987 to December 1989, 265 patients were enrolled in this study, and 231 are evaluable for response. After stratification according to institution and ECOG performance status (PS), the patients were randomly allocated to receive either standard FAC therapy (group A) or FAC plus lonidamine (600 mg orally daily three times a day) (group B). After three FAC courses, the patients with no progressive disease were further randomized to either receive continuous treatment up to the time of tumor progression (maximum: 10 courses) or to discontinue therapy when a response "plateau" was reached. In this latter group, the same therapy was restarted at relapse or disease progression. Objective response (complete response plus partial response) was significantly higher in group B (66.3%) compared to group A (42.3%). The actuarial median times to disease progression was also significantly longer (P less than 0.0001) in group B (median 9 months) than in group A (median 6 months). Other than myalgia and gastric pain, no increased toxicity was observed in the lonidamine. The analysis of second randomization are yet available because of the longer follow-up time required. Present findings suggest an interesting additive effect of lonidamine when combined with FAC chemotherapy and warrant further investigation in other therapeutic regimens and in other neoplastic diseases.
