Purpose. To evaluate the effects of epoetin alfa on patient- reported outcomes (PROs) in patients with breast cancer receiving myelotoxic chemotherapy. Materials and Methods. Women with hemoglobin concentrations ≤12.0 g/dl and an Eastern Cooperative Oncology Group performance status (ECOG PS) score of 0-3 were randomized 1:1 to receive epoetin alfa (10,000 IU 3 times weekly) or best standard care (BSC) during chemotherapy. The primary endpoint was the change from baseline in the total anemia subscale assessed by the Functional Assessment of Cancer Therapy-Anemia (FACT-An) questionnaire after 12 weeks of treatment. The fatigue and nonfatigue subscales from the FACT An, the Cancer Linear Analog Scale (CLAS), hemoglobin changes, ECOG PS score, tumor response, overall survival, and safety also were evaluated. Results. Of 223 patients randomized, 216 constituted the modified intent-to-treat population. Percentage changes in the total anemia subscale of the FACT-An were significantly different between epoetin alfa treatment (14.2%) and BSC (-0.5%; p =.002), favoring epoetin alfa; so were changes in the FACT-An fatigue subscale (epoetin alfa, 17.5%; BSC, -0.9%; p =.003) and nonfatigue subscale (epoetin alfa, 8.8%; BSC, 0.2%; p =.008). Similar results were observed with the CLAS. Hemoglobin concentrations >12 g/dl were more common with epoetin alfa (62.0%) than with BSC (27.6%). Tumor response, ECOG PS score, 12-month survival rate, and the incidence of serious treatmentemergent adverse events were similar between groups. Conclusion. Early intervention with epoetin alfa was well tolerated and improved anemia-related PROs in patients with breast cancer receiving myelotoxic chemotherapy. © AlphaMed Press. Source

Background: Hereditary nonpolyposis colorectal cancer (HNPCC) is caused by heterozygous mutations in mismatch repair (MMR) genes. Approximately 85 % of genetically defined HNPCC patients have germline mutations in MLH1 and MSH2. HNPCC patients are at increased risk of developing extracolonic cancers. The early age of onset, predominantly right-sided colon cancers, and synchronous and metachronous cancers are other features of the syndrome. HNPCC shows heterogeneous clinical phenotypes, and differences in gene mutation frequencies have been observed in some countries. Several investigators have tried to correlate the phenotype with the affected gene. Methods: A total of 46 individuals from 22 unrelated families, of the 264 families fulfilling the inclusion criteria, with deleterious mutations in MLH1, MSH2, or MSH6 genes were identified. We evaluated these clinicopathological features in their relation to different genetic parameters (gene mutated, type of mutation, or alteration of the MMR system in high-risk families) in order to establish a relationship between the phenotype and the genotype in our series. Results: The phenotype of the disease seems not to be influenced by the type of mutation, but rather by the mutated gene. The presence of multiple tumors is associated with mutations in the MSH2 gene. The mean age at diagnosis of the first colorectal cancer (CRC) was almost identical in families with mutations in MLH1 and MSH2, about 50 years of age, but this age may increase by almost 10 years for MSH6 mutation carriers. Conclusion: The identification of genotype-phenotype correlations could provide a more specific surveillance program focused on the individualized risk. © 2013 Springer-Verlag Berlin Heidelberg.

Background: Lactate dehydrogenase (LDH) represents a predictive factor in colorectal cancer patients treated with the angiogenesis inhibitor PTK/ZK. We explored the role of pre-treatment LDH serum levels in colorectal cancer patients receiving first-line bevacizumab.Methods:Metastatic colorectal cancer treated with first-line bevacizumab was eligible. A control group including all consecutive patients treated with chemotherapy alone was also considered. Pre-treatment LDH serum levels were collected for all cases.Results:Median progression-free survival (PFS) in the control group for patients with high and low LDH levels was 4.2 and 8 months, respectively (P=0.0003). Median overall survival (OS) was 19.6 and 34.9 months for patients with high and low LDH levels, respectively (P=0.0014). In the bevacizumab group, partial responses were seen in 14 (58%) high-LDH and 8 (14%) low-LDH patients (P=0.0243), respectively, median PFS was 7.3 and 8.5 months, respectively (P=0.2), and median OS was 22 and 26.6 months, respectively (P=0.7). Conclusion: High LDH levels correlated with worse prognosis. Bevacizumab seemed capable of improving clinical outcome in this specific group of patients who usually present with an adverse natural history. The improved response rate also suggests a role for LDH as a predictive marker. © 2012 Cancer Research UK All rights reserved. Source

Aims and background. The social cost of management of patients suffering from colorectal cancer has been growing dramatically in the last decade due to the high number of active antitumor agents and to the increased incidence of the tumor in western countries. The aim of the study was to explore from a pharmacoeconomic point of view a different way to administer the twomost common regimens in this patient setting. Study design. This was a cost-minimization study. Data were extracted from hospital registries and dedicated offices. The traditional setting (day hospital inpatient setting) and a fully ambulatory setting (CIP™ pump) were considered and compared. Results. The CIP™ system resulted in higher direct costs than the day hospital setting (444.70 vs 159.00 euro/cycle). However, traditional infusion resulted in longer nursing care, with an increase in nursing costs of more than 100.00 euro/cycle. Moreover, the inpatient setting obliged patients to stay in the hospital as much as ten times longer than with the CIP™ system. This meant that with the same time span and the same resources, the CIP™ pump permitted treatment of at least five times more patients than the traditional setting. Thus, a threshold of 52.00 euro per patient for general hospital costs (ordinary and extraordinary maintenance of buildings, power supply, and housekeeping) was identified to discriminate whether the CIP™ pump is cost-saving or not. Conclusions. Administration of the FOLFIRI or FOLFOX regimen in a traditional day hospital setting was less costly when considering the direct costs. However, a fully ambulatory pump permitted to better employ hospital resources and could permit cost-saving in those units in which more than five patients per day are treated and global costs are higher than 52.00 euro per patient.

Context: Premenopausal patients with breast cancer are at high risk of premature ovarian failure induced by systemic treatments, but no standard strategies for preventing this adverse effect are yet available. Objective: To determine the effect of the temporary ovarian suppression obtained by administering the gonadotropin-releasing hormone analogue triptorelin during chemotherapy on the incidence of early menopause in young patients with breast cancer undergoing adjuvant or neoadjuvant chemotherapy. Design, Setting, and Patients: The PROMISE-GIM6 (Prevention of Menopause Induced by Chemotherapy: A Study in Early Breast Cancer Patients - Gruppo Italiano Mammella 6) study, a parallel, randomized, open-label, phase 3 superiority trial, was conducted at 16 sites in Italy and enrolled 281 patients between October 2003 and January 2008. The patients were premenopausalwomenwith stage I through III breast cancerwhowere candidates foradjuvant or neoadjuvant chemotherapy. Assuminga 60% rate of early menopause in the group treated with chemotherapy alone, it was estimated that 280 patients had to be enrolled to detect a 20% absolute reduction in early menopause in the group treated with chemotherapy plus triptorelin. The intention-to-treat analysis was performed by including all randomized patients and using imputed values for missing data. Interventions: Before beginning chemotherapy, patients were randomly allocated to receive chemotherapy alone or combined with triptorelin. Triptorelin was administered intramuscularly at a dose of 3.75 mg at least 1 week before the start of chemotherapy and then every 4 weeks for the duration of chemotherapy. Main Outcome Measure: Incidence of early menopause (defined as no resumption of menstrual activity and postmenopausal levels of follicle-stimulating hormone and estradiol 1 year after the last cycle of chemotherapy). Results: The clinical and tumor characteristics of the 133 patients randomized to chemotherapy alone and the 148 patients randomized to chemotherapy plus triptorelin were similar. Twelve months after the last cycle of chemotherapy (last follow-up, August 18, 2009), the rate of early menopause was 25.9% in the chemotherapy-alone group and 8.9% in the chemotherapy plus triptorelin group, an absolute difference of -17% (95% confidence interval, -26% to -7.9%; P<.001). The odds ratio for treatment-related early menopause was 0.28 (95% confidence interval, 0.14 to 0.59; P<.001). Conclusion: The use of triptorelin-induced temporary ovarian suppression during chemotherapy in premenopausal patients with early-stage breast cancer reduced the occurrence of chemotherapy-induced early menopause.
