Colorectal tumors with complete obstruction – Endoscopic recovery of passage replacing emergency surgery? A report of two cases

BACKGROUND: Incomplete or complete obstructive ileus due to colorectal cancer is generally treated by emergency surgery that has higher morbidity and mortality than elective surgery. CASE PRESENTATION: Here we describe an endoscopic technique by which a safe bowel decompression was performed instead of emergency surgery in two patients with complete tumorous obstruction of the colon. By means of a polypectomy snare, a soft wire, an ERCP catheter, a set of endoscopes with different diameters (baby endoscope, gastroscope) and of argon plasma coagulation the tumor mass was reduced and the tumor stenosis was passed. The patients recovered from symptoms of colon obstruction, no procedure-associated complications were observed. One patient had surgery of the sigmoid tumor one week later (UICC-stage III), the other patient (UICC-stage IV) received systemic chemotherapy starting one week after endoscopic decompression. CONCLUSION: Complete tumorous obstruction of the colon may be managed by endoscopic tumor debulking avoiding high risk emergency surgery and allowing immediate medical treatment of the primary tumor and of metastases

Darbepoetin alfa for treating chemotherapy-induced anemia in patients with a baseline hemoglobin level < 10 g/dL versus ≥10 g/dL: an exploratory analysis from a randomized, double-blind, active-controlled trial

<p>Abstract</p> <p>Background</p> <p>Several studies have shown that darbepoetin alfa, an erythropoiesis-stimulating agent (ESA), can reduce transfusions and increase hemoglobin (Hb) levels in patients with chemotherapy-induced anemia (CIA). Recent safety concerns, however, have prompted changes to ESA product information. In the European Union and United States, ESA therapy initiation for CIA is now recommended at a Hb level ≤10 g/dL. The present exploratory analysis examined how ESA initiation at this Hb level may impact patient care.</p> <p>Methods</p> <p>Data from a phase 3 randomized trial were retrospectively reanalyzed. CIA patients with nonmyeloid malignancies were randomized 1:1 to 500 mcg darbepoetin alfa every three weeks (Q3W) or 2.25 mcg/kg darbepoetin alfa weekly (QW) for 15 weeks. A previously published report from this trial showed Q3W dosing was non-inferior to QW dosing for reducing transfusions from week 5 to end-of-the-treatment period (EOTP). In the present analysis, outcomes were reanalyzed by baseline Hb <10 g/dL and ≥10 g/dL. Endpoints included transfusion rates, Hb outcomes, and safety profiles.</p> <p>Results</p> <p>This study reanalyzed 351 and 354 patients who initiated ESA therapy at a baseline Hb of <10 g/dL or ≥10 g/dL, respectively. From week 5 to EOTP, the estimated Kaplan-Meier transfusion incidence (Q3W vs QW) was lower in the ≥10 g/dL baseline-Hb group (14% vs 21%) compared with the <10 g/dL baseline-Hb group (36% vs 41%). By week 5, the ≥10 g/dL baseline-Hb group, but not the <10 g/dL baseline-Hb group, achieved a mean Hb ≥11 g/dL. The Kaplan-Meier estimate of percentage of patients (Q3W vs QW) who achieved Hb ≥11 g/dL from week 1 to EOTP was 90% vs 85% in the ≥10 g/dL baseline-Hb group and 54% vs 57% in the <10 g/dL baseline-Hb group. Both baseline-Hb groups maintained mean Hb levels <12 g/dL and had similar safety profiles, though more patients in the ≥10 g/dL baseline-Hb group reached the threshold Hb of ≥13 g/dL.</p> <p>Conclusion</p> <p>In this exploratory analysis, darbepoetin alfa Q3W and QW raised Hb levels and maintained mean Hb at <12 g/dL in both baseline-Hb groups. The ≥10 g/dL baseline-Hb group had fewer transfusions and faster anemia correction. Additional studies should prospectively evaluate the relationship between Hb levels at ESA initiation and outcomes.</p> <p>Trial Registration</p> <p>ClinicalTrials.gov Identifier NCT00118638.</p

High prevalence of anaemia and limited use of therapy in cancer patients : a Belgian survey (Anaemia Day 2008)

Objectives: The aim of this study is to provide relevant and accurate information on prevalence and treatment patterns of anaemia in Belgian cancer patients. Methods The Anaemia Day 2008 survey was a single visit, multi-centre, non-interventional study in adult cancer patients under systemic therapy (chemotherapy, hormonal, immunological and/or targeted therapy) and/or radiotherapy. Efforts were made to enrol the maximum number of patients seen in each centre that day. Patients signed an informed consent and relevant data were collected from their files, i.e. disease and disease stage, cancer therapy and anti-anaemic treatment, including transfusions and the use of erythropoietin stimulating agents (ESA). A blood count of each included patient was performed. Haemoglobin (Hb) values (grams per decilitre) were classified into four categories to assess the severity of anaemia, as defined byWHO: no anaemia: Hb≥12 g/dL; mild 10≤Hb≤11.9 g/dL; moderate 8≤Hb≤9.9 g/dL; severe Hb< 8 g/dL. Univariate and multivariate analyses were carried out with anaemia as the dependent variable. Results A total of 1,403 eligible patients aged 63±13 years (mean age±SD) were enrolled in 106 oncology or haematology centres. The mean Hb level (±SD) was 11.6 g/dL (±1.8 g/dL) and the prevalence of anaemia (Hb<12 g/dL) was 55.7% (95% CI, 53.1–58.3%), respectively, 35.9% mild, 17.8% moderate and 2.1% severe anaemia. Anaemia was more frequent in females than in males, and in patients with haematological malignancies (73.4%) than in those with solid tumours (51.4%; p<0.001). Anaemia prevalence was higher in hospitalised patients (75.5%) compared to those seen in one-day-clinic (54.3%) or in consultation (33.9%; p<0.001), and in patients treated with chemotherapy (61.3%) compared to those receiving radiotherapy (34.4%) or hormonal therapy (19.5%; p<0.001). There was a clear correlation between severity of anaemia and WHO performance status (p< 0.001). Among anaemic patients, 53.1% received no treatment (mean Hb 10.8±0.9 g/dL). Among the anaemic patients who received therapy for their anaemia (mean Hb 9.7±1.1 g/dL), the most frequent treatments were RBC transfusions (42%), ESA (34.6%), transfusions+ESA (12%), ESA+iron (7.9%) and iron alone (3.5%). Comparison to the ECAS survey shows that there has been no major change in attitude towards anaemia management in the last decade. Conclusion This survey shows that cancer-related anaemia is still frequently observed in cancer patients. Even if in our study ESA were used more frequently than about 10 years ago, still a large amount of anaemic patients who could be treated for anaemia according to EORTC guidelines, were not
