EFFICACY AND SAFETY OF CLADRIBINE: SUBCUTANEOUS VERSUS INTRAVENOUS ADMINISTRATION IN HAIRY CELL LEUKEMIA PATIENTS

Cladribine induces durable complete remission (CR) in approximately 85% of hairy cell leukemia (HCL) patients. In Egypt, cladribine is mainly used as IV continuous infusion at a dose of 0.1 mg/kg/day for 7 days and as SC bolus injection at a dose of 0.14 mg/kg/day for 5 days. We aimed to compare the outcome and toxicity between these two regimens. We retrospectively collected data of HCL patients treated at the National Cancer Institute and its affiliated center, Nasser Institute, Cairo, Egypt. Forty nine patients were identified, 18 treated with the IV regimen (IV group) and 31 with the SC regimen (SC group). Forty-one patients were newly diagnosed. Patient characteristics were balanced across the two groups. The CR rates in the IV and the SC group were 94% and 97%, respectively. The main complications in the IV group and the SC were neutropenia G3-4 (67% vs 87%), mucositis mainly G1-2 (67% vs 32%) and infections (mainly viral, 78% vs 34%). In the IV group, 5 patients died, 3 of progression and infection, one of unknown cause and one of late heart failure. In the SC group, one patient died of disease progression and one of second cancer. After 33.5 months median follow up, the 3-year event free survival was 60% and 96%, respectively (p=0.104). The 3-year overall survival was 81% and 100%, respectively (p=0.277). Lymphadenopathy and/or hepatomegaly may have negative influence on DFS. In conclusion, SC cladribine is an excellent alternative to the IV regimen for the treatment of HCL.  Key words: 2-chlorodeoxyadenosine, cladribine, hairy cell leukemia, intravenous, subcutaneou

Improved overall survival with Gemtuzumab Ozogamicin (GO) compared with best supportive care (BSC) in elderly patients with untreated acute myeloid leukemia (AML) not considered fit for intensive chemotherapy: final results from the randomized phase III study (AML-19) of the EORTC and gimema leukemia groups

Epidemiology and Outcome of Fungemia in a Cancer Cohort of the Infectious Diseases Group (IDG) of the European Organization for Research and Treatment of Cancer (EORTC 65031)

In a prospective cohort study of 145 030 admissions of cancer patients from 13 European Organisation for Research and Treatment of Cancer centers fungemia occurred in 0.23%. Candida albicans was the predominant pathogen. Fungemia was associated with substantial mortality. Antifungal prophylaxis and remission of cancer predicted better surviva

Survival improvement over time of 960 s-AML patients included in 13 EORTC-GIMEMA-HOVON trials

We report the outcomes of secondary acute myeloid leukemia (s-AML) patients included in one of 13 European Organisation for Research and Treatment of Cancer (EORTC) collaborative AML trials using intensive remission-induction chemotherapy. Among 8858 patients treated between May 1986 and January 2008, 960 were identified as having s-AML, either after MDS (cohort A; n = 508), occurring after primary solid tumors or hematologic malignancies other than MDS (cohort B; n = 361), or after non-malignant conditions or with a history of toxic exposure (cohort C; n = 91). Median age was 64 years, 60 years and 61 years in cohort A, B and C, respectively. Among patients ≤60 years and classified in the cohorts A or B (n = 367), the 5-year overall survival (OS) rate was 28%. There was a systematic improvement in the 5-year OS rate over three time periods (p 60 years of age (n = 502), the OS was dismal, and there was no improvement over time

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

Acute myeloid leukemia developing in patients with autoimmune diseases

Therapy-related acute myeloid leukemia is an unfortunate complication of cancer treatment, particularly for patients with highly curable primary malignancies and favorable life expectancy. The risk of developing therapy-related acute myeloid leukemia also applies to patients with non-malignant conditions, such as autoimmune diseases treated with cytotoxic and/or immunosuppressive agents. There is considerable evidence to suggest that there is an increased occurrence of hematologic malignancies in patients with autoimmune diseases compared to the general population, with a further increase in risk after exposure to cytotoxic therapies. Unfortunately, studies have failed to reveal a clear correlation between leukemia development and exposure to individual agents used for the treatment of autoimmune diseases. Given the dismal outcome of secondary acute myeloid leukemia and the wide range of available agents for treatment of autoimmune diseases, an increased awareness of this risk and further investigation into the pathogenetic mechanisms of acute leukemia in autoimmune disease patients are warranted

Current knowledge and future research directions in treatment-related second primary malignancies

AbstractCurrently, 17–19% of all new primary malignancies occur in survivors of cancer, causing substantial morbidity and mortality. Research has shown that cancer treatments are important contributors to second malignant neoplasm (SMN) risk.In this paper we summarise current knowledge with regard to treatment-related SMNs and provide recommendations for future research. We address the risks associated with radiotherapy and systemic treatments, modifying factors of treatment-related risks (genetic susceptibility, lifestyle) and the potential benefits of screening and interventions. Research priorities were identified during a workshop at the 2014 Cancer Survivorship Summit organised by the European Organisation for Research and Treatment of Cancer.Recently, both systemic cancer treatments and radiotherapy approaches have evolved rapidly, with the carcinogenic potential of new treatments being unknown. Also, little knowledge is available about modifying factors of treatment-associated risk, such as genetic variants and lifestyle. Therefore, large prospective studies with biobanking, high quality treatment data (radiation dose–volume, cumulative drug doses), and data on other cancer risk factors are needed. International collaboration will be essential to have adequate statistical power for such investigations. While screening for SMNs is included in several follow-up guidelines for cancer survivors, its effectiveness in this special population has not been demonstrated. Research into the pathogenesis, tumour characteristics and survival of SMNs is essential, as well as the development of interventions to reduce SMN-related morbidity and mortality. Prediction models for SMN risk are needed to inform initial treatment decisions, balancing chances of cure and SMNs and to identify high-risk subgroups of survivors eligible for screening
