BiOsimilaRs in the management of anaemia secondary to chemotherapy in HaEmatology and Oncology: results of the ORHEO observational study.

BACKGROUND: The approval of epoetin biosimilars in the European Union requires extensive scientific evaluation and stringent regulatory procedures, including post-marketing studies. The ORHEO (place of biOsimilaRs in the therapeutic management of anaemia secondary to chemotherapy in HaEmatology and Oncology) study was an observational, longitudinal, multicentre study performed in France to evaluate the efficacy and safety of biosimilar epoetins for the treatment of chemotherapy-induced anaemia (CIA) in the clinical setting. METHODS: Patients >18 years with CIA (haemoglobin [Hb] <11 g/dL) in association with solid tumours, lymphoma or myeloma and eligible for treatment with an epoetin biosimilar were included in this study. Patient characteristics were recorded at baseline along with anaemia-related information, such as observed and target Hb (as chosen by the treating clinician), brand and dose of epoetin biosimilar prescribed, and details of any other treatments. Patients were then followed-up at 3 and 6 months. The primary endpoint was Hb response (defined as Hb reaching ≥10 g/dL, an increase of Hb ≥1 g/dL since inclusion visit or reaching physician-defined target Hb, with no blood transfusions in the 3 weeks prior to measurement). Other endpoints included adverse events, achievement of target Hb and associated treatments. RESULTS: Overall, 2333 patients >18 years (mean age 66.5 years) with CIA (haemoglobin [Hb] <11 g/dL) in association with solid tumours, lymphoma or myeloma and eligible for biosimilar epoetin treatment were included. 99.9% of patients received epoetin zeta (median dose 30,000 IU/week). Mean baseline Hb was 9.61 g/dL, with 35.6% of patients having moderate anaemia (Hb 8-9.5 g/dL). Hb response was achieved in 81.6% and 86.5% of patients at 3 and 6 months, respectively. Overall mean change in Hb level was 1.52 ± 1.61 and 1.72 ± 1.61 g/dL at 3 and 6 months, respectively. Transfusion and thromboembolic event rates were 9.4% and 2.4% at 3 months, and 5.8% and 1.5% at 6 months, respectively. CONCLUSIONS: Epoetin zeta was effective and well tolerated in the management of CIA in patients with solid tumours, lymphoma and myeloma. TRIAL REGISTRATION NUMBER: NCT02140736 (date of registration: 14 May 2014).

Baseline Splenic Volume as a Prognostic Biomarker of FOLFIRI Efficacy and a Surrogate Marker of MDSC Accumulation in Metastatic Colorectal Carcinoma.

BACKGROUND: Predictive biomarkers of response to chemotherapy plus antiangiogenic for metastatic colorectal cancer (mCRC) are lacking. The objective of this study was to test the prognostic role of splenomegaly on baseline CT scan. METHODS: This study is a sub-study of PRODIGE-9 study, which included 488 mCRC patients treated by 5-fluorouracil, leucovorin and irinotecan (FOLFIRI) and bevacizumab in first line. The association between splenic volume, and PFS and OS was evaluated by univariate and multivariable Cox analyses. The relation between circulating monocytic Myeloid derived suppressor cells (mMDSC) and splenomegaly was also determined. RESULTS: Baseline splenic volume > 180 mL was associated with poor PFS (median PFS = 9.2 versus 11.1 months; log-rank p = 0.0125), but was not statistically associated with OS (median OS = 22.6 versus 28.5 months; log-rank p = 0.1643). The increase in splenic volume at 3 months had no impact on PFS (HR 0.928; log-rank p = 0.56) or on OS (HR 0.843; log-rank p = 0.21). Baseline splenic volume was positively correlated with the level of baseline circulating mMDSC (r = 0.48, p-value = 0.031). CONCLUSION: Baseline splenomegaly is a prognostic biomarker in patients with mCRC treated with FOLFIRI and bevacizumab, and a surrogate marker of MDSC accumulation.

Localized amyloidosis: a survey of 35 French cases.

Since the prognosis of localized amyloidosis remains unclear, we conducted a survey to define the characteristics and the course of this disease. The charts of 35 patients with either laryngeal (14 patients), tracheobronchial (10 patients), colonic (1 patient), or lower urinary tract amyloidosis (10 patients) were analyzed. The average age at diagnosis was 52.7+/-12 years (range 33-73 years). The amyloid protein type was specified to be amyloid light chain (AL) in 15 cases. All patients had undergone additional biopsies (accessory salivary glands, rectal, fat pad and bone marrow aspirates) to rule out a systemic disease. Symptomatic treatments included endoscopic excision and laser therapy. Colchicine and chemotherapy with prednisone and melphalan were prescribed with limited success. During a mean follow-up period of 6.1+/-5.3 years no patient developed a systemic form of amyloidosis. Six deaths were reported, one related to the disease because of a fatal airway hemorrhage. We suggest that immunolabeling studies should be more routinely performed. There was no risk of developing a systemic disease from local amyloid deposits in our survey. However, local evolution can be life-threatening. Such patients should be referred to specialist centers for further evaluation. Management requires close follow-up to exclude recurrence and to determine the appropriate symptomatic treatment.

[Psoriasis and systemic lupus erythematosus: a rare association with specific therapeutic problems]. / Psoriasis et lupus érythémateux disséminé: une association rare, des problèmes thérapeutiques spécifiques.

The association psoriasis and systemic lupus erythematosus (SLE) is a very uncommon association. We report three cases, diagnosed in an Internal Medicine department between 1993 and 2000. Few cases of psoriasis/SLE have been published in the literature. Psoriasis generally precedes the diagnosis of SLE. Psoriasis can also be associated with discoid lupus erythematosus. In some cases, SLE appears as a complication of ultraviolet phototherapy indicated for the psoriasis. The association psoriasis/SLE does not seem to have distinctive immunologic features. Specific therapeutic difficulties may occur. Indeed, hydroxychloroquine may exacerbate the psoriasis. Systemic use of corticosteroids raises the risk of severe psoriasis relapse during withdrawal. In addition, the diagnosis of psoriasic arthropathy is more difficult in this setting. The psoriasis/SLE association might be a good indication for using methotrexate.
