Factors influencing patient's perception of long-term treatment with low-molecular-weight heparins for cancer-associated thrombosis: an updated analysis of TROPIQUE, a prospective observational study.

PURPOSE: Our objective was to compare patient's expectations to their experience and to identify factors predictive of patient's perception of long-term LMWH for the treatment of cancer-associated thrombosis (CAT). METHODS: Results from the validated Perception Anticoagulant Treatment Questionnaires (PACTQ) completed before inclusion (PACTQ1 for expectations) and at the end (PACTQ2 for convenience and satisfaction) of the 6-month TROPIQUE study were studied with principal component analysis. Possible predictive factors of improved perception of LMWH treatment were analyzed with the Kruskall-Wallis test. RESULTS: Among 409 included patients treated with LMWH, 269 PACT-Q1 and 139 PACT-Q2 were evaluable for treatment perception. Patients had high expectations (A1-A7 score of 26.7 ± 3.5, max = 35). Treatment cost (A7 = 1.90 ± 1.31) and concern about a mistake in anticoagulation (A5 = 1.93 ± 1.12) had little importance while LMWH treatment was considered easy to use (A4 = 4.20 ± 0.93). Six-month treatment with LMWH was associated with a high rate of convenience (B1-B11, C1-C2 = 55.1 ± 8.38, max = 65) and a high satisfaction score (D1-D7 = 25.1 ± 4.32, max = 35). Patients' confidence in treatment and perception of possible LMWH side effects were moderate while perception of autonomy and independence significantly improved at the end of the study compared to inclusion. PACT-Q2 satisfaction score was low in patients who experienced bleeding (PACT-Q2 24.1 ± 3.3 vs. 25.1 ± 4.3). LMWH twice daily tended to be found less convenient compared than once daily (53.3 ± 7.2 vs. 55.0 ± 8.3). CONCLUSION: CAT patients had a good perception of the 6-month LMWH treatment when comparing expectations and experience. Using a quantitative scale validated in the general population for VTE and subcutaneous injection and including a large number of patients, bleeding complications and LMWH twice daily were associated with a nonsignificant trend towards a worsen perception.

FOLFIRINOX as induction treatment in rectal cancer patients with synchronous metastases: Results of the FFCD 1102 phase II trial.

AIM OF THE STUDY: The optimal therapeutic strategy in patients with rectal cancer and synchronous unresectable metastases remains unknown. We evaluated the efficacy of FOLFIRINOX induction therapy in this setting. PATIENTS AND METHODS: Chemotherapy-naïve patients received at least 8 cycles of FOLFIRINOX. The primary end-point was the 4-month disease control (4 m DC) rate. Tumour responses were centrally reviewed and assessed by computed tomography scan for metastases (Response Evaluation Criteria in Solid Tumours criteria) and magnetic resonance imaging for rectal tumorus. With a Simon 2-stage design and a targeted (H1) 4 m DC > 75%, 65 patients were enrolled from July 2012 to February 2015: male, 78%; median age, 61 years; performance status, 0-1, 98%; liver metastases, 92%; ≥2 metastatic sites, 63%. RESULTS: Fifty-six (85%) of the 65 patients received the 8 planned FOLFIRINOX cycles. The primary objective was achieved (4 m DC rate: 94%; 95% confidence interval [CI], 86.3-97.8). Primary tumour symptoms decreased from 72% at baseline to 10% at 4 months. Response rate was 86%, and a >70% primary tumour volume decrease was seen in 63% of patients. Forty-four patients (68%) had at least one grade 3 side-effect; no toxic deaths occurred. Median follow-up was 35.0 months (95% CI, 31.3-43.7). Median progression-free survival and overall survival were 10.9 m (95% CI, 8.8-12.9) and 33.4 m (95% CI, 22.6-38.2), respectively. CONCLUSION: Upfront FOLFIRINOX is feasible and allows good local and distant control. It therefore offers the opportunity to choose the best therapeutic strategy for each patient and to personalise treatment according to the local and distant efficacy results of this induction step.

Poorly differentiated gastro-entero-pancreatic neuroendocrine carcinomas: Are they really heterogeneous? Insights from the FFCD-GTE national cohort.

BACKGROUND: Diagnosis and management of poorly differentiated gastro-entero-pancreatic (GEP) neuroendocrine carcinomas (NECs) remain challenging. Recent studies suggest prognostic heterogeneity. We designed within the French Group of Endocrine Tumours a prospective cohort to gain insight in the prognostic stratification and treatment of GEP-NEC. PATIENTS AND METHODS: All patients with a diagnosis of GEP-NEC between 1st January 2010 and 31st December 2013 could be included in this national cohort. Adenoneuroendocrine tumours were excluded. RESULTS: 253 patients from 49 centres were included. Median age was 66 years. Main primary locations were pancreas (21%), colorectal (27%), oesophagus-stomach (18%); primary location was unknown in 20%. Tumours were metastatic at diagnosis in 78% of cases. Performance status (PS) at diagnosis was 0-1 in 79% of patients. Among the 147 (58%) cases reviewed by an expert pathological network, 39% were classified as small cell NEC and 61% as large cell NEC. Median Ki67 index was 75% (range, 20-100). Median overall survival was 15.6 (13.6-17.0) months. Significant adverse prognostic factors in univariate analysis were PS > 1 (hazard ratio [HR] = 2.5), metastatic disease (HR = 1.6), NSE>2 upper limit of normal [ULN]; HR = 3.2), CgA>2 ULN (HR = 1.7) and lactate dehydrogenase >2 ULN (HR = 2.1). After first-line palliative chemotherapy (CT1) with platinum-etoposide (n = 152), objective response, progression-free survival and overall survival were 50%, 6.2 and 11.6 months; they were 24%, 2.9 and 5.9, respectively, after post-CT1 FOLFIRI regimen (n = 72). CONCLUSIONS: We report a large prospective series of GEP-NEC which show the predominance of large cell type and advanced stage at diagnosis. Prognosis was found more homogeneous than previously reported, mainly impacted by PS and tumour burden.

Safety and efficacy of FOLFIRINOX in elderly patients with metastatic or locally advanced pancreatic adenocarcinoma: A retrospective analysis.

BACKGROUND: FOLFIRINOX is a polychemotherapy regimen currently used to treat inoperable pancreatic cancer in patients with a good performance status (PS). FOLFIRINOX lengthens overall survival time (OS), but no specific data are available in elderly patients. METHODS: All cases of inoperable pancreatic adenocarcinoma in patients over 70 years old treated with FOLFIRINOX were retrospectively reviewed between 2008 and 2015 in five institutions in France. The primary objective was to evaluate the safety and efficacy of FOLFIRINOX in the elderly. RESULTS: Forty-two patients with a median age of 73 years (range: 70-79) and a median PS of 1 (range: 0-2) were included. 88% of patients treated with FOLFIRINOX were enrolled between 2012 and 2015. 24 patients (57%) needed a primary dose reduction but this did not impact OS (median OS 11.7 months (6.9-16.4) compared to 16.6 months (0.37-32.8) without dose reduction, p = 0.69). Twelve patients (29%) experienced grade 3 toxicity. Sensory neuropathy occurred most often (56%). Primary prophylaxis with granulocyte colony stimulating factor (GCSF) was administered to 14 patients (33%). One treatment-related death occurred (septic shock), although this patient had not had primary prophylaxis with GCSF. Median follow-up was 86 months. Median OS was 11.6 months (95%CI: 8.9-14.3). CONCLUSION: Median OS observed in the elderly was similar to OS previously reported in younger patients in the ACCORD 11 trial. FOLFIRINOX is effective in selected, fit elderly patients but with greater grade 3 neurotoxicity. Primary dose reduction and primary GCSF prophylaxis may control tolerance.

[Tolerance of bevacizumab therapy in systemic sclerosis-associated pulmonary arterial hypertension: A case report]. / Tolérance du bévacizumab au cours de l'hypertension artérielle pulmonaire associée à la sclérodermie systémique : à propos d'une observation.

INTRODUCTION: No data is available regarding the safety of bevacizumab, an anti-vascular endothelial growth factor-A (VEGF-A) antibody, in patients with pulmonary arterial hypertension (PAH), a condition in which VEGF seems to play a significant and probably protective role. CASE REPORT: We report a patient with a history of systemic sclerosis-associated PAH, stable under bosentan therapy. She was diagnosed with metastatic cervical epidermoid carcinoma and treated by two successive cytotoxic chemotherapy regimens. As these treatments failed to control disease progression, she was started on anti-angiogenic therapy: 3 infusions of bevacizumab 15 mg/kg were administered. Over the course of this treatment, no change in the clinical status or echocardiography parameters was noted. CONCLUSION: This observation suggests that, under careful clinical and echocardiographic follow-up, bevacizumab therapy can be well tolerated in case of stable and moderate PAH. Decision of treatment should be taken cautiously, as the possibility of PAH worsening is not excluded.

Plasma and tissue proteomic prognostic factors of response in primary breast cancer patients receiving neoadjuvant chemotherapy.

A pathological complete response (pCR) after neoadjuvant chemotherapy is observed in approximately 20% of breast cancer patients. A proteomic analysis was performed on plasma and tumor tissue before treatment to evaluate its potential impact on the prediction of response. One hundred and forty-nine breast cancer patients eligible for neoadjuvant chemotherapy were included in the study between February 2004 and January 2009 at three centers. The proteomic analysis was performed using SELDI Technology (ProteinChip CM10 pH4, IMAC-Cu and H50). Three acquisition protocols were used according to the mass range. Plasma and tumor proteomic signatures were generated using generalized ROC criteria and cross-validation. Twenty-eight (18.8%) patients out of 149 experienced a pCR according to Sataloff criteria. In the cytosol analysis, respectively 4, 2 and 8 proteins had significantly different levels of expression in the responders and non-responders using IMAC-Cu, H50 and CM10 pH4. Among the 8 proteins of interest on CM10 pH4, 2 (C1 and C7) were selected and were validated in 95.0 and 85.6% of the models. In the plasma analysis, respectively 12, 6 and 2 proteins had different levels of expression using the same proteinchips. Among the 12 plasma proteins of interest on IMAC-Cu, 2 (P1 and P7) were selected and were validated in 94.8 and 97.6% of the models. A combined proteomic signature was generated, which remained statistically significant when adjusted for hormone receptor status and Ki-67. Our results show that proteomic analysis can differentiate complete pathological responders in breast cancer patients after neoadjuvant chemotherapy.

Megestrol acetate versus metronomic cyclophosphamide in patients having exhausted all effective therapies under standard care.

BACKGROUND: To evaluate the antitumour activity and safety of metronomic cyclophosphamide vs megestrol acetate in progressive and advanced cancer patients having exhausted all effective therapies under standard care. METHODS: Patients were randomly assigned to receive orally metronomic cyclophosphamide (50 mg b.i.d) or megestrol acetate (160 mg only daily) until intolerance or progression (RECIST 1.0). The primary efficacy end point was a 2-month progression-free rate (PFR(2m)). According to Optimal Simon's design and the following assumptions, namely, P0=5%, P1=20%, alpha=beta=10%, the treatment is considered as effective if atleast 5 out of 44 patients achieved PFR(2m). RESULTS: Between September 2006 and January 2009, 88 patients were enrolled. Two patients experienced grade 3-4 toxicities in each arm (4%). One toxic death occurred in the megestrol acetate arm as a consequence of thrombosis. The metronomic cyclophosphamide arm reached the predefined level of efficacy with a PFR(2m) rate of 9 out of 44 and a PFR(4m) rate of 5 out of 44. The MA arm failed to achieve the level of efficacy with a PFR(2m) of 4 out of 44 and a PFR(4m) of 1 out of 44. The median overall survival was 195 and 144 days in the metronomic cyclophosphamide arm and megestrol acetate arm, respectively. CONCLUSION: Metronomic cyclophosphamide is well tolerated and provides stable disease in such vulnerable and poor-prognosis cancer patients. This regimen warrants further evaluations.

[Antiphospholipid syndrome with only antiphosphatidylethanolamine antibodies: report of 20 cases]. / Syndrome des antiphospholipides avec anticorps antiphosphatidyléthanolamine isolés: à propos de 20 cas.

PURPOSE: The association of antiphosphatidylethanolamine antibodies (aPE) as the only antiphospholipid antibody with antiphospholipid syndrome (APS) is discussed. The aPE was described as the sole antibody in many cases suggesting APS. aPE was not included in the Sapporo criteria for the classification of APS. METHODS: We investigated the clinical features of 20 patients with aPE only; 17 patients had symptoms potentially related to APS (group 1) and three had other manifestations (group 2). RESULTS: There were 15 women and five men, mean age was 35 +/- 12 years at the beginning. In group 1 (n = 17), ten patients presented arterial thrombosis, nine venous thrombosis (five had both), and six microvascular thrombosis (livedo reticularis, lacunar pathology). The aPE positivity was persistent in 13 patients. A subgroup of four patients (three women) presented arteriosclerosis with peripheral arteriopathy which started before 45 years of age. They had another atherosclerosis risk factor associated with aPE persistence. In group 2 (n = 3), there was no thrombotic event, one demyelinating pathology, one microvascular pathology, and one arterial dysplasia. The aPE positivity was never confirmed. Finally, 13 patients presented an APS with aPE only, confirmed at least 8 weeks later. CONCLUSIONS: Our study points out that testing for aPE would be of interest for patients when symptoms were potentially related to APS, particularly when other antiphospholipid antibodies were negative. This description questions the enlargement of the APS biological criteria defined in Sapporo. The role of aPE in atherosclerosis is considered.
