Cancer and chemotherapy can have adverse effects on cognitive functions and quality of life of patients. We wanted to know the patients' view on these disorders, but also their expectations in terms of assessment and support.

Prospective monocentric study of the toxicities related to concurrent administration of trastuzumab to breast radiotherapy.

Met pathway is activated in many solid cancers. In advanced non-small cell lung cancer (NSCLC), Met amplification is involved in 5 to 20% of acquired resistance to EGFR tyrosine kinase inhibitors (TKI) in tumors with initially sensitive EGFR mutation. MetMab (onartuzumab) is a monoclonal single-arm humanized anti-Met antibody. Its fixation on the Met receptor prevents the binding of the ligand (Hepatocyte Growth factor [HGF]) and the signal transduction. After promising results in preclinical and phase I trials, a randomized phase II trial has been conducted in advanced NSCLC in 2nd or 3rd line treatment. One hundred and twenty-eight patients have been randomized between an association of erlotinib+placebo and erlotinib+MetMab (15mg/kg IV every 3 weeks) until progression or toxicity. Patients with overexpression of Met in immunohistochemistry (IHC) had a progression-free survival (PFS) and an overall survival (OS) two-fold (median 1.5 versus 2.9 months; HR=0.53; P=0.04) and three-fold (median 3.8 versus 12.6 months; HR=0.37; P=0.002) longer, respectively, than patients with negative IHC score. The erlotinib+MetMab association had a worse effect on SSP and OS than the control arm in patients with negative IHC. The toxicity profile of MetMab is very good, and the main adverse effect is the occurrence of peripheral edemas, most of the time of low grade. A randomized phase III is on going to validate these results.

The occurrence of hyperpigmentation during chemotherapy is one of the most frequent dermatological adverse events observed with these drugs. It may arise with numerous anticancer agents, and can be either localized or diffuse, occurring either immediately or after inflammatory dermatological lesions. Nails, mucosa and skin may all be affected. Though the incidence is high in clinical practice, such drug-induced hyperpigmentation has been only rarely individualized and characterized. Herein we describe the main clinical, histological and pathophysiological characteristics of these lesions and the most frequently incriminated chemotherapeutic agents, as well as the anatomical areas involved and the most specific clinical patterns such as flagellate dermatitis, reticulate or serpentine supravenous hyperpigmentation and eruptive naevi.

Cancer is a rare disease in teenagers with only 800 new cases each year in France. Different tumor types are diagnosed in this age group, mainly hematologic malignancies (leukemias and lymphomas), bone and soft tissue sarcomas, germ cell tumors and brain tumors. Besides the need of a specific psycho-social support for the patients and their families, one of the main issues in treating cancer in this age group is the existence of disparities of in the choice of treatment according to the type of structures (adult or pediatric) in which patients are treated. The impact of these disparities on the outcome of patients is still unknown and this issue requires a better collaboration of adult and pediatric teams involved in the care of these patients in order to optimize their treatment.

The incidence of lung cancer during pregnancy is very low, but it is becoming more frequent in industrialized countries both because of the increase in smoking in young women and because women are becoming pregnant later in life. Usually, the cancer has a poor prognosis due to the presence of metastatic disease at the time of diagnosis. Diagnosis and management are delicate, and should deal with the gestational age, the maternal prognosis, the fetal toxicity of treatments, but also with the worsening of maternal prognosis and the risk of neoplastic cells being transmitted to the fetus in case of delayed treatment. Psychological and ethical considerations complicate the decision process. We present a review of the epidemiology, clinical characteristics, management, and prognosis concerning lung cancer during pregnancy. Finally, it is important to remember that young women with lung cancer should be advised to use a reliable form of contraception.

For a few years, new targeted therapies have been used for metastatic cancers, targeting VEGF and its receptors and improving patients' survival for metastatic carcinoma (kidney, GIST, breast, colorectal). The objective of these treatments is to block either circulating VEGF (bevacizumab; VEGF-Trap), or tyrosine kinase receptors (especially the VEGF receptor) (sorafenib, sunitinib, brivanib, imatinib, etc.). Indeed, VEGF stimulates endothelial cell proliferation and then tumour growth and metastasis. However, all these antiangiogenic drugs share similar side effects, most frequently gastrointestinal disturbance, skin toxicity and hypertension. Hypertension seems to be especially frequent in case of good response. Renal side effects have probably been underestimated in the first place and their exact frequency is not known, needing some specific trials and registries. Proteinuria, thrombotic microangiopathies and acute renal failures have been reported: renal biopsies might be necessary for precise evaluation of renal damages. Physiopathology seems very close to preeclampsia. Good collaboration between oncologists, nephrologists and cardiologists is therefore crucial in order to continue these targeted therapies safely for the patients.

The objective of this paper is to review the literature published in 2011 in the field of intensive care and emergency related to oncology. Are discussed because of new original publications: prognosis, resuscitation techniques, oncologic emergencies, serious toxicities of cytotoxic chemotherapy and targeted therapies, complicated aplastic anemia, toxicity of bisphosphonates, respiratory complications, pulmonary embolism and neurological complications.

Azacitidine (5-azacytidine, VIDAZA) is a disease-modifying agent that improves survival, reduces transfusion dependence, and reduces progression to acute myeloid leukemia in patients with higher risk myelodysplastic syndromes. Azacitidine injection is associated with characteristic adverse events (AEs) that must be managed in order for patients to stay on therapy and achieve optimal therapeutic outcomes. These AEs include injection-site reactions, cytopenias, and gastrointestinal effects. Oncology nurses are uniquely positioned to provide patient support and counselling, thereby helping patients and their families set clear expectations for azacitidine therapy. This article presents a nursing standard designed to support Canadian oncology nurses in the key areas of counselling for patients initiating and continuing azacitidine, as well as nursing strategies for prevention and management of azacitidine-associated AEs. Many of the general principles discussed in this nursing standard can be applied broadly to many diseases and treatments.

This report is concerned with the development of an hemolytic uremic syndrome (HUS) in 6 patients (3 males, 3 females, aged 53 to 73) suffering from an advanced cancer and treated by protracted (>= 4 months) infusions of gemcitabine. Over 4 to 14 months, the patients received 13-34 infusions delivering a cumulative dose oscillating between 9 and 29 g/m2. A progressive alteration of renal function preceeded the acute syndrome. After interruption of gemcitabine and symptomatic treatment, the evolution of haemolytic anemia was generally favourable. This was not the case for renal dysfunction: 2 complete and 1 partial resolution of renal insufficiency were noted, but 1 case required chronic dialysis. Based on the authors experience, the frequency of an HUS complication after protracted gemcitabine treatment could be as high as 2.7 %.

Macrophage migration inhibitory factor is a critical proinflammatory cytokine produced by cells of innate and adaptive immune system. MIF plays a key role in cell cycle regulation and in the pathogenesis of many cancers. Recently, MIF has been studied in the upper aerodigestive tract cancer for its involvement in tumor progression, invasion, proliferation and cell motility. In addition, MIF appears to be a mediator in angiogenesis and in the development of metastasis and locoregional lymph node, which are often associated with a poor prognosis. The mechanisms of action responsible for MIF involvement in tumor progression are not completely elucidated. However, the main effects of MIF are mediated by the CD74 receptor. MIF binding to its receptor is responsible for the activation of several signaling pathways (ERK1/2 - MAPK, JAB1 - CSN5, PI3K - Akt), the inhibition of p53 and the stimulation of angiogenic factors including VEGF and IL-8. The overexpression of MIF also causes a reduction of the anti-tumor activity of the immune system. Finally, MIF could be an interesting biomarker in the diagnosis and monitoring of upper aerodigestive tract cancers. In this paper, we assess the state of knowledge of MIF involvement in upper aero-digestive tract cancers and we analyze the therapeutic perspectives.

Trastuzumab emtansine (T-DM1) is an antibody-drug conjugate (ADC) which associates the selective intracellular targeting of the cytotoxic agent, DM1 (maytansine derivative) to the antitumor activity of trastuzumab. T-DM1 targets the epidermal growth factor receptor 2 (HER2), highly expressed in the most aggressive forms of breast cancer. Current standard of care in HER2-positive advanced or metastatic breast cancers has its limitations, particularly after progression on HER2-targeted approved therapies. T-DM1 showed a significant antitumor activity in vitro and in vivo, and in experimental models resistant to HER2-targeted agents. Phase I and II studies showed that the maximum tolerated dose for T-DM1 is 3.6 mg/kg given intravenously every three weeks. At this recommended dose, T-DM1 provided objective tumor responses and favourable safety profile. A phase II randomised study, evaluating T-DM1 in first line vs trastuzumab plus docetaxel, the current standard of care in advanced or metastatic breast cancers, showed improved tolerability and efficacy. Recently, the results of EMILIA, a phase III randomised study assessing, after prior treatment with trastuzumab and a taxane, the efficacy and the safety of T-DM1 vs lapatinib plus capecitabine, confirmed the therapeutic benefit. T-DM1 appears to be an effective therapeutic option to treat patients with HER2-positive metastatic breast cancer.

Since the advent of targeted molecules, the treatment and prognosis of many cancers, especially chronic myeloid leukemia (CML), have been substantially modified through the introduction of first- and second-generation tyrosine kinase inhibitors. Skin effects constitute the most common adverse effects of these new substances. Although such skin changes are not life-threatening, they can have extensive clinical impact, in some cases leading to discontinuation of treatment.

Neovascularisation is a hallmark of cancer. Vascular endothelial growth factor (VEGF) is directly involved in the regulation of this tumoural neoangiogenesis, especially in lung cancer. Bevacizumab is a humanized monoclonal antibody targeting VEGF that is commonly used in thoracic oncology. Among the side effects, perforation of the nasal septum is rare.
