Randomized Trial of Intravenous Iron Supplementation in Patients With Chemotherapy-Related Anemia Without Iron Deficiency Treated With Darbepoetin Alfa

PURPOSE Unresponsiveness to erythropoiesis-stimulating agents, occurring in 30% to 50% of patients, is a major limitation to the treatment of chemotherapy-related anemia. We have prospectively evaluated whether intravenous iron can increase the proportion of patients with chemotherapy-related anemia who respond to darbepoetin. PATIENTS AND METHODS Between December 2004 and February 2006, 149 patients with lung, gynecologic, breast, and colorectal cancers and >or= 12 weeks of planned chemotherapy were enrolled from 33 institutions. Patients were required to have hemoglobin <or= 11 g/L and no absolute or functional iron deficiency. All patients received darbepoetin 150 microg subcutaneously once weekly for 12 weeks and were randomly assigned to sodium ferric gluconate 125 mg intravenously (IV) weekly for the first 6 weeks (n = 73) or no iron (n = 76). Primary end point of the study was the percentage of patients achieving hematopoietic response (hemoglobin >or= 12 g/dL or >or= 2 g/dL increase). RESULTS Hematopoietic response by intention-to-treat analysis was 76.7% (95%CI, 65.4% to 85.8%) in the darbepoetin/iron group and 61.8% (95%CI, 50.0% to 72.7%) in the darbepoetin group (P = .0495). Among patients fulfilling eligibility criteria and having received at least four darbepoetin administrations, hematopoietic responses in the darbepoetin/iron group (n = 53) and in the darbepoetin-only group (n = 50) were 92.5% (95% CI, 81.8% to 97.9%) and 70% (95% CI, 55.4% to 82.1%), respectively (P = .0033). Increase of hemoglobin during treatment period showed a time profile favoring darbepoetin/iron with statistically significant effect from week 5 on. The safety profile was comparable in the two arms. CONCLUSION In patients with chemotherapy-related anemia and no iron deficiency, IV iron supplementation significantly reduces treatment failures to darbepoetin without additional toxicity.

Detecting disabilities in older patients with cancer: comparison between comprehensive geriatric assessment and vulnerable elders survey-13.

PURPOSE Comprehensive geriatric assessment (CGA) is a multidimensional method used by geriatricians and oncologists to detect and evaluate multiple age-related problems and to plan and coordinate interventions. Because its main drawback is the time required, efforts have been made to evaluate screening instruments suitable for preliminarily assessing elderly patients. The main aim of this study was to establish the accuracy of the Vulnerable Elders Survey-13 (VES-13) in predicting the presence of abnormalities revealed by CGA. PATIENTS AND METHODS Patients age > or = 70 years with a histologically or cytologically confirmed diagnosis of a solid or hematologic tumor underwent both CGA and a VES-13 assessment, and the reliability and validity of VES-13 were analyzed. Results Fifty-three percent of the 419 elderly patients with cancer (mean age, 76.8 years) were vulnerable on VES-13; the rates of disabilities on CGA and activities of daily living (ADLs)/instrumental activities of daily living (IADLs) scales were 30% and 25%, respectively. The sensitivity and specificity of VES-13 were 87% and 62%, respectively, versus CGA and 90% and 70%, respectively, versus ADL/IADL scales. CONCLUSIONS On the basis of our data, VES-13 is highly predictive of impaired functional status and can thus be considered a useful preliminary means of assessing older patients with cancer before undertaking a full CGA.

Role of plasma EBV DNA levels in predicting recurrence of nasopharyngeal carcinoma in a western population

BackgroundLoco-regionally advanced nasopharyngeal carcinomas can be cured by the combination of chemotherapy and radiotherapy. In Eastern countries, plasma levels of viral Epstein-Barr deoxyribonucleic acid (DNA) are accurate in predicting recurrence, but few data are available in Western populations. The aim of this prospective study was to evaluate the relationship between viral Epstein-Barr DNA copy numbers in plasma and the response rate, progression-free survival and overall survival in a cohort of Western patients with stage IIb-IVb nasopharyngeal cancer.MethodsWe evaluated plasma samples from 36 consecutive patients treated with induction chemotherapy followed by chemoradiation. EBV copy numbers were determined after DNA extraction using real-time quantitative polymerase chain reaction. Survival curves were estimated using the Kaplan–Meier method.ResultsCirculating Epstein-Barr virus DNA levels were measured before treatment, at the end of concomitant chemo- and radiotherapy, and during the follow-up period. Pre-treatment levels significantly correlated with the initial stage and probability of relapse. Their increase was 100% specific and 71.3% sensitive in detecting loco-regional or metastatic recurrence (an overall accuracy of 94.4%). Three-year progression-free and overall survival were respectively 78.2% and 97.1%.ConclusionsThe results of this study confirm that patients from a Western country affected by loco-regionally advanced nasopharyngeal carcinoma have high plasma Epstein-Barr virus DNA levels at diagnosis. The monitoring of plasma levels is sensitive and highly specific in detecting disease recurrence and metastases.

Estimating the risk of chemotherapy toxicity in older patients with cancer: The role of the Vulnerable Elders Survey-13 (VES-13).

OBJECTIVE Some parameters of the Comprehensive Geriatric Assessment (CGA) are predictive of chemotherapy toxicity. The Vulnerable Elders Survey-13 (VES-13) is a short instrument that has been tested as a means of identifying patients who need a full CGA, but its ability to predict chemotherapy toxicity is still unclear. We performed a pooled analysis of four published clinical trials studying VES-13 as a means of diagnosing vulnerability, in order to evaluate its accuracy in predicting the risk of grade 3/4 toxicity in older patients undergoing chemotherapy. MATERIALS AND METHODS The study involved patients aged ≥ 66 years with a diagnosis of solid or hematological cancer, all of whom were administered VES-13. The number of medications taken by each patient, their comorbidities, their Cumulative Illness Rating Scale for Geriatrics (CIRS-G) score and index, the type of chemotherapy and treatment line, and their Mini Mental State Evaluation (MMSE), and Mini Nutritional Assessment (MNA) scores were recorded. Information was available concerning the grades 3-4 hematological and non-hematological toxicities experienced by each patient. RESULTS The study involved 648 patients aged ≥ 66 years (mean age 76.2±4.5, range 66-90) of whom 336 (51.9%) were female. VES-13 identified 287 patients (44.3%) as vulnerable. Grades 3-4 hematological and non-hematological toxicities were more prevalent in the vulnerable subjects (35.2% vs 20.8%, p<0.0001, and 18.5% vs 10.8%, p=0.0055), who were also at higher risk of both (adjusted ORs 2.15, 95% CI 1.46-3.17, p<0.001); and 1.66 (95% CI 1.02-2.72, p=0.043). CONCLUSIONS VES-13 could be considered to be a good candidate for future prospective studies to assess older patients with cancer at risk of toxicity.

Sorafenib does not improve efficacy of chemotherapy in advanced pancreatic cancer: A GISCAD randomized phase II study

BACKGROUND The RAF-MEK-ERK pathway is commonly activated in pancreatic cancer because of a high frequency of KRAS-BRAF mutations. A phase II randomized trial was designed to investigate the activity of sorafenib in combination with chemotherapy in advanced pancreatic cancer. METHODS Locally advanced or metastatic pancreatic adenocarcinoma patients were randomized in a 1:1 ratio to receive cisplatin plus gemcitabine with sorafenib 400mg bid (arm A) or without sorafenib (arm B). RESULTS One hundred and fourteen patients were enrolled; of these, 43 (74.6%) patients progressed in arm A and 44 (82.4%) in arm B. Median progression-free survival was 4.3 months (95% CI: 2.7-6.5) and 4.5 months (95% CI: 2.5-5.2), respectively (HR=0.92; 95% CI: 0.62-1.35). Median overall survival was 7.5 (95% CI: 5.6-9.7) and 8.3 months (95% CI: 6.2-8.7), respectively (HR=0.95; 95% CI: 0.62-1.48). Response rates were 3.4% in arm A and 3.6% in arm B. CONCLUSIONS Sorafenib does not significantly enhance activity of chemotherapy in advanced pancreatic cancer patients, and therefore should not be assessed in phase III trials.

A phase II study of carboplatin and paclitaxel for recurrent or metastatic head and neck cancer.

The aim of this study was to investigate the activity and safety of a regimen containing carboplatin and paclitaxel in patients affected by recurrent or metastatic head and neck cancer. Eligible patients were treated with a 3-week combination of paclitaxel 175 mg/m2 and carboplatin area under the concentration time curve 5 mg/ml/min for a maximum of four cycles. A total of 27 patients entered the study. One patient (3.7%) had a complete response, whereas six patients (22.2%) obtained a partial response. Stable disease was observed in seven patients (25.9%). The disease control rate was 51.8% (95% confidence interval: 32.0–71.3), whereas overall response rate was 25.9% (95% confidence interval: 11.1–46.3). The median overall survival was 8.0 months (range: 2–27), with a 1-year survival of 30.5%. The median progression-free survival was 1.0 month (range: 0–14). Treatment-related deaths or episodes of neutropenic fever were not registered. Grades 3–4 neutropenia was observed in two patients (7.4%), grades 3–4 anaemia and thrombocytopenia in four (14.8%) and one (3.7%) patients, respectively. Nine patients (33.3%) experienced grades 1–2 and one patient (3.7%) grade 3 peripheral neuropathy. The combination of carboplatin and paclitaxel is safe and moderately effective for the treatment of recurrent or metastatic head and neck cancer.

Locoregionally advanced nasopharyngeal carcinoma: induction chemotherapy with cisplatin and 5-fluorouracil followed by radiotherapy and concurrent cisplatin: a phase II study.

Background: Chemoradiotherapy is the current standard of care for locoregionally advanced nasopharyngeal carcinoma. The purpose of this study was to assess the feasibility and efficacy of induction chemotherapy (CHT) followed by concomitant chemoradiotherapy in this patient population. Patients and Methods: In this single-arm, phase II study, patients with locoregionally advanced nasopharyngeal carcinoma were treated with 3 cycles of induction CHT with cisplatin (100 mg/m2 on day 1) and 5-fluorouracil (1,000 mg/m2 continuous infusion on days 1–4) followed by 3 cycles of cisplatin (100 mg/m2 on days 1, 22 and 43) and concurrent radiotherapy up to 70 Gy. The primary endpoint was objective response. Results: Thirty-four patients were enrolled, and all completed both induction treatment and subsequent chemoradiotherapy. Objective response rates were 79.4% (95% CI 62.1–91.3) and 85.3% (95% CI 68.9–95.0) after induction CHT and chemoradiation, respectively. Treatment was well tolerated and toxicity was manageable. At a median follow-up of 29 months, 3-year overall survival and progression-free survival rates are 80.0% (95% CI 0.64–0.95) and 54.0% (95% CI 0.36–0.73), respectively. Conclusions: Induction CHT with cisplatin and 5-fluorouracil followed by concomitant chemoradiotherapy is a feasible and active regimen for patients with stage IIB–IVB nasopharyngeal carcinoma. This regimen resulted in excellent locoregional disease control and overall survival.

Single agent panitumumab in KRAS wild-type metastatic colorectal cancer patients following cetuximab-based regimens: Clinical outcome and biomarkers of efficacy

Background Few data are available outlining outcomes of panitumumab in advanced colorectal cancer patients benefiting from prior cetuximab-based regimens. Patients and methods Thirty patients with KRAS wild type metastatic colorectal cancer with clinical benefit from prior cetuximab-based regimens between May 2004 and October 2011 were reviewed at nine Italian Institutions. Inclusion key criteria included interruption of cetuximab for reasons other than progressive disease. Patients were classified according to prior regimens (0 or ≥1), prior response or stabilization, surgery of metastases, and Köhne prognostic score. At the time of subsequent progression, patients were treated with single agent panitumumab until progressive disease, unacceptable toxicity, or consent withdrawal. Results Panitumumab obtained 67% disease control rate and 30% objective response rate, with median PFS of 4.2 and median OS of 9.6 mo. Patients with BRAF/NRAS/PI3KCA and KRAS (by mutant enriched technique) wild-type tumors had the best chance of response to panitumumab. Conclusions Single agent panitumumab provided significant clinical benefit in heavily pretreated patients without acquired resistance to prior cetuximab-based regimens.

Biomolecular Markers in Cancer of the Tongue

The incidence of tongue cancer is increasing worldwide, and its aggressiveness remains high regardless of treatment. Genetic changes and the expression of abnormal proteins have been frequently reported in the case of head and neck cancers, but the little information that has been published concerning tongue tumours is often contradictory. This review will concentrate on the immunohistochemical expression of biomolecular markers and their relationships with clinical behaviour and prognosis. Most of these proteins are associated with nodal stage, tumour progression and metastases, but there is still controversy concerning their impact on disease-free and overall survival, and treatment response. More extensive clinical studies are needed to identify the patterns of molecular alterations and the most reliable predictors in order to develop tailored anti-tumour strategies based on the targeting of hypoxia markers, vascular and lymphangiogenic factors, epidermal growth factor receptors, intracytoplasmatic signalling and apoptosis.

The value of lactate dehydrogenase serum levels as a prognostic and predictive factor for advanced pancreatic cancer patients receiving sorafenib

Although lactate dehydrogenase (LDH) serum levels, indirect markers of angiogenesis, are associated with a worse outcome in several tumours, their prognostic value is not defined in pancreatic cancer. Moreover, high levels are associated even with a lack of efficacy of tyrosine kinase inhibitors, contributing to explain negative results in clinical trials. We assessed the role of LDH in advanced pancreatic cancer receiving sorafenib. Seventy-one of 114 patients included in the randomised phase II trial MAPS (chemotherapy plus or not sorafenib) and with available serum LDH levels, were included in this analysis. Patients were categorized according to serum LDH levels (LDH ≤vs.> upper normal rate). A significant difference was found in progression free survival (PFS) and in overall survival (OS) between patients with LDH values under or above the cut-off (PFS: 5.2 vs. 2.7 months, p = 0.0287; OS: 10.7 vs. 5.9 months, p = 0.0021). After stratification according to LDH serum levels and sorafenib treatment, patients with low LDH serum levels treated with sorafenib showed an advantage in PFS (p = 0.05) and OS (p = 0.0012). LDH appears to be a reliable parameter to assess the prognosis of advanced pancreatic cancer patients, and it may be a predictive parameter to select patients candidate to receive sorafenib.
