Invasive breast cancer is the most common malignancy in women in industrialized countries. Three-quarters of breast cancers express estrogen and/or progesterone receptors and are considered endocrine-sensitive. Endocrine therapy reduces the risk of loco-regional, contralateral and distant recurrence. The management has become more complex with estrogen receptor inhibitors, aromatase inhibitors and ovarian function suppression. The choice of the regimen and its duration depend on the age, the menopausal status of the patient, her co-morbidities, the risk of cancer relapse and the tolerance. We summarize here the recent modifications of the endocrine therapy in early and advanced stage breast cancer.

Diarrhea is one of the most common complaints in oncologic patients. Causes are multiple including bowel resection, infections, radiation and systemic anti-cancer treatments. In the latter case, the pathophysiology is partially elucidated and requires the etiology to be precisely identified : chemotherapy, targeted therapy or immunotherapy. Loperamide remains central in uncomplicated cases. However, with development of immunotherapy, autoimmune mechanism should be recognized and requires different approach based mainly on corticosteroids. Physician taking care of patients with diarrhea should therefore identify possible causes in order to offer adapted treatments and therefore reduce morbidity and mortality.

Despite major advances in prevention and treatment, febrile neutropenia remains one of the most concerning complications of cancer chemotherapy. Its prognosis depends directly on the quality of the initial management in the emergency department (ED). An initial assessment of circulatory and respiratory function, with vigorous resuscitation where necessary, should be followed by careful examination for potential source of infection. A broad-spectrum empirical antibacterial therapy should be given in a timespan < 1 hour. Multinational Association for Supportive Care in Cancer (MASCC) criteria were developed to help physicians make decisions about the site of care and overall management of these patients.

The incidence of cancer is raising and the treatments are increasingly aggressive. Consequently, physicians are regularly facing side effects of cytotoxic therapies. Cancer- therapy-induced cardiotoxicity is a serious complication because it can be fatal and causes a temporary or permanent cessation of the treatment. In this article, we summarize the mechanisms, the monitoring and the multidisciplinary management of patients with cancer-therapy induced cardiotoxicity.

We have just celebrated the 50th anniversary of cisplatin cytotoxic potential discovery. It is time to take stock… and it seems mainly positive. This drug, that revolutionized the treatment of many cancer types, continues to be the most widely prescribed chemotherapy. Despite significant toxicities, resistance mechanisms associated with treatment failures, and unresolved questions about its mechanism of action, the use of this cytotoxic agent remains unwavering. The interest concerning this "old" invincible drug has not yet abated. Indeed many research axes are in the news. New platinum salts agents are tested, new cisplatin formulations are developed to target tumor cells more efficiently, and new combinations are established to increase the cytotoxic potency of cisplatin or overcome the resistance mechanisms.

Ifosfamide remains one of the major cytotoxic drugs for sarcoma management. Ifosfamid-related encephalopathy (IRE) is a rare but severe adverse event, without clearly identified risk factors.

Sorafenib is the standard treatment for advanced hepatocellular carcinoma (HCC). Due to its peculiar toxicities, improving patient's tolerance may need close follow-up. Nurses can play a crucial role, by driving a patient education program (EP). We aimed to prove that adding EP to usual care (UC) improves patient's care.

Differentiated thyroid cancers are usually cured by an appropriate surgery and a radioiodine remnant ablation. If metastases occur, successive radioiodine administrations and/or local treatments can be provided. Nevertheless, some patients will be, or become refractory to radioiodine. In case of significant and rapid progression of metastatic lesions, they will be candidate to kinase inhibitor treatments. Two agents are now approved in this situation: sorafenib and lenvatinib. Lenvatinib (Lenvima®) is a tyrosine kinase inhibitor (TKI) targeting the VEGFR1-3, FGFR 1-4, PDGFR-α, RET and c-kit. It received an FDA and EMA approval in February and March 2015 for the treatment of radioiodine refractory thyroid cancers following the SELECT study's results. In this study, patients treated with lenvatinib had a significant increase in progression-free survival (18.3 months vs. 3.6 months; HR=0.21; CI=0.14-0.31, P < 0.001) and response rate (64.8% vs. 1.5% with placebo). The median overall survival was not reached in both groups at the time of data cutoff. In France, lenvatinib was first available within a compassionate use program (ATU) and is now dispended by hospitals because not yet marketed.

The concept of high-doses chemotherapy was developed in the 1980s based on in vitro scientific observations. Exposure of tumor cells to increasing concentrations of alkylating agents resulted in increased cell death in a strong dose-response manner. Moreover, the acquired resistance of tumor cells could be overcome by dose intensification. In clinic, dose intensification of alkylating agents resulted in increased therapeutic responses, however associated with significant hematological toxicity. Following the development of autologous stem cells transplantation harvesting from peripheral blood, the high-doses of chemotherapy, initially associated with marked toxic effects, could be more easily tolerated. As a result, the approach was evaluated in different types of solid tumors, including breast, ovarian and germ cell tumors, small cell lung carcinoma, soft tissue sarcomas and Ewing sarcoma. To date, high-doses chemotherapy with hematopoietic stem cells support is only used as a salvage therapy to treat poor prognosis germ cell tumors patients with chemo-sensitive disease. Regarding breast and ovarian cancer, high-doses chemotherapy should be considered only in the context of clinical trials. However, intensive therapy as an approach to overcome resistance to standard treatments is still relevant. Numerous efforts are still ongoing to identify novel therapeutic combinations and active treatments to improve patients' responses.

The acquisition of a resistance EGFR mutation in exon 20 (T790M) occurs in half of the cases of secondary resistance to EGFR tyrosine kinase inhibitors (TKI), given in first-line treatment in advanced EGFR-mutated non-small cell lung cancers (NSCLC). Osimertinib (AZD9291, Tagrisso®) is a third-generation, irreversible EGFR TKI, active in case of T790M mutation. A large phase I trial showed the efficacy of osimertinib after failure of first-generation EGFR TKI (erlotinib, gefitinib), with response rate at 51% and up to 61% in case of T790M mutation. Progression-free survival was 9.6 months in case of T790M. Toxicity profile was acceptable, with mainly digestive (diarrhea) and skin (rash) side effects. Preliminary data from a phase II trial confirmed these efficacy and safety data. Screening of T790M mutation at the time of progression with TKI can be performed in circulating tumor DNA in plasma, with good diagnostic performances.

Imiquimod is a local immune-response modifier that works by stimulating innate and acquired immunity. It is frequently used to treat superficial basal cell carcinoma, the most common form of skin cancer. Marked local inflammatory reaction is common during treatment. We report a case of the rare condition, multiple eruptive milia, during topical imiquimod therapy.

Intracerebral hemorrhage (ICH) remains a cause of death in hematologic malignancies. Asparaginase represents a key agent in the treatment of acute lymphoblastic leukemia (ALL). The toxicity of asparaginase includes coagulopathy such as thrombotic or bleeding tendency. We report a case of fatal cerebral hemorrhage in a 12-year-old girl treated for ALL. Cerebral hemorrhage occurred after three injections of L-asparaginase. The patient presented with hypofibrinogenemia (0.36g/L), associated with thrombocytopenia (24,000/mm3). Despite maximal medical and surgical treatment (platelets and fresh-frozen plasma transfusions, red blood cells transfusion, fibrinogen replacement therapy, and craniotomy discharge), the patient died. L-asparaginase is well known for its prothrombotic action. By inhibiting the synthesis of fibrinogen and factors V, VII, VIII, and IX, it causes an increased risk of bleeding, including intracranial bleeding. Predictive scores for ICH onset have been established but there is no consensus on the management of coagulation disorders induced by L-asparaginase. It is recommended to check fibrinogen and antithrombin (AT) blood values in order to substitute them if they drop to < 1 g/L for fibrinogen and < 60% for AT. The management of asparaginase-induced ICH does not differ from that of ICH of other origin. The risk of death is high, and surgical treatment has not proven superior to medical therapy in terms of mortality rates and 6-month survival. Further studies are needed to define consensus guidelines for coagulation disorders induced by asparaginase and also to define the specific management in cases of ICH in childhood hematological malignancies.
