The use of chemotherapy regimens carrying a moderate or high risk of febrile neutropenia and the corresponding management of febrile neutropenia: an expert survey in breast cancer and non-Hodgkin's lymphoma

The use of chemotherapy regimens with moderate or high risk of febrile neutropenia (defined as having a FN incidence of 10% or more) and the respective incidence and clinical management of FN in breast cancer and NHL has not been studied in Belgium. The existence of a medical need for G-CSF primary and secondary prophylaxis with these regimens was investigated in a real-life setting.Journal ArticleMulticenter StudyResearch Support, Non-U.S. Gov'tSCOPUS: ar.jinfo:eu-repo/semantics/publishe

Incidence of reversible amenorrhea in women with breast cancer undergoing adjuvant anthracycline-based chemotherapy with or without docetaxel

<p>Abstract</p> <p>Background</p> <p>To determine the incidence of reversible amenorrhea in women with breast cancer undergoing adjuvant anthracycline-based chemotherapy with or without docetaxel.</p> <p>Methods</p> <p>We studied the incidence and duration of amenorrhea induced by two chemotherapy regimens: (i) 6 cycles of 5-fluorouracil 500 mg/m², epirubicin 100 mg/m²and cyclophosphamide 500 mg/m²on day 1 every 3 weeks (6FEC) and (ii) 3 cycles of FEC 100 followed by 3 cycles of docetaxel 100 mg/m²on day 1 every 3 weeks (3FEC/3D). Reversible amenorrhea was defined as recovery of regular menses and, where available (101 patients), premenopausal hormone values (luteinizing hormone (LH), follicle-stimulating hormone (FSH) and estradiol) in the year following the end of chemotherapy.</p> <p>Results</p> <p>One hundred and fifty-four premenopausal patients were included: 84 treated with 6FEC and 70 with 3FEC/3D. The median age was 43.5 years (range: 28–58) in the 6FEC arm and 44 years (range: 29–53) in the 3FEC/3D arm. Seventy-eight percent of patients were treated in the context of the PACS 01 trial. The incidence of chemotherapy-induced amenorrhea at the end of chemotherapy was similar in the two groups: 93 % in the 6FEC arm and 92.8 % in the 3FEC/3D arm. However, in the year following the end of chemotherapy, more patients recovered menses in the 3FEC/3D arm than in the 6FEC arm: 35.5 % versus 23.7 % (p = 0.019). Among the 101 patients for whom hormone values were available, 43 % in the 3FEC/3D arm and 29 % in the 6FEC arm showed premenopausal levels one year after the end of chemotherapy (p < 0.01). In the 3FEC/3D group, there was a statistically significant advantage in disease-free survival (DFS) for patients who were still amenorrheic after one year, compared to patients who had recovered regular menses (p = 0.0017).</p> <p>Conclusion</p> <p>Our study suggests that 3FEC/3D treatment induces more reversible amenorrhea than 6FEC. The clinical relevance of these findings needs to be investigated further.</p

Phase II study of sunitinib in recurrent or metastatic squamous cell carcinoma of the head and neck: GORTEC 2006-01

PURPOSE To assess the efficacy and toxicity of sunitinib monotherapy in palliative squamous cell carcinoma of the head and neck (SCCHN). PATIENTS AND METHODS Thirty-eight patients with SCCHN having evidence of progressive disease (PD) were treated with sunitinib 37.5 mg/d given continuously until PD or unacceptable toxicity. The primary end point was the rate of disease control, defined as stable disease (SD) or partial response (PR) at 6 to 8 weeks after treatment initiation (two-stage design, Simon). Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) was performed in a subset of patients before and 6 to 8 weeks after treatment. The volume transfer constant of the contrast agent (K(trans)) was used to measure changes in the microcirculation blood flow and endothelial permeability of the tumor. Results A PR was observed in one patient, SD in 18, and PD in 19 (Response Evaluation Criteria in Solid Tumors [RECIST]), resulting in a disease control rate of 50%. Among the 18 patients with SD, there were five unconfirmed PRs and six additional minor responses. A significant decrease in K(trans) was seen in three of the four patients who received DCE-MRI monitoring. Grade 5 head and neck bleeds occurred in four patients. Local complications, including the appearance or worsening of tumor skin ulceration or tumor fistula, were recorded in 15 patients. CONCLUSION Sunitinib demonstrated modest activity in palliative SSCHN. The severity of some of the complications highlights the importance of improved patient selection for future studies with sunitinib in head and neck cancer. Sunitinib should not be used outside clinical trials in SSCHN

Phase 1 Study Evaluating the Association of the Cyclin-Dependent Kinase 4/6 Inhibitor Ribociclib and Cetuximab in Recurrent/Metastatic p16-Negative Squamous Cell Carcinoma of the Head and Neck.

BACKGROUND: The majority of human papillomavirus (HPV)-negative squamous cell carcinoma of the head and neck (SCCHN) present upregulation of the epidermal growth factor receptor (EGFR) and frequent alterations in the cyclin D1-cyclin dependent kinase (CDK) 4/6 (CDK 4/6)-retinoblastoma protein (pRb) pathway, resulting in cell cycle progression and tumor proliferation. This study investigated the combination of ribociclib, an orally highly selective inhibitor of CDK 4/6, and cetuximab in recurrent and/or metastatic (R/M) SCCHN. METHODS: A phase I trial using a 3 + 3 design was performed to determine the dose limiting toxicity (DLT) and maximum tolerated dose (MTD) of ribociclib with standard dose of weekly cetuximab in HPV-negative patients with R/M SCCHN. Ribociclib was administered orally (3 weeks on/1 week off) at dose level 1 of 400 mg daily and dose level 2 of 600 mg daily. The MTD of ribocilib was then further evaluated in an expansion cohort. RESULTS: 10 patients were enrolled in the escalation trial. No DLTs were observed at dose level 1 (n = 3); at dose level 2, one patient was replaced due to rapid disease progression, and one patient out of six evaluable patients experienced a DLT (grade 4 thrombocytopenia >7 days). Ribociclib 600 mg daily was thus determined to be the MTD. Eleven additional patients were enrolled in the expansion cohort. Diarrhea (52%), rash (52%), fatigue (43%), nausea (33%), and mucositis (28%) were the most frequent grade 1-2 adverse events (AE). Neutropenia was the most frequent grade 3-4 AE (20%). Median progression-free survival (PFS) was 3.5 months (range 0.4-17.3 months) and median overall survival (OS) was 8.3 months (range 0.4-24.1 months). Among the 19 radiologically evaluable patients, two (10.5%) achieved a partial response and 11 (58%) had stable disease. CONCLUSIONS: The MTD of ribociclib is 600 mg daily when administered in combination with standard dose cetuximab for 3 weeks on and 1 week off. This combination was safe and showed efficacy. Further clinical trials should be conducted to evaluate the antitumor effects of this combination. TRIAL INFORMATION: ClinicalTrials.gov: NCT02429089; Eudract number 2014-005371-83

Phase II study of figitumumab in patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck : clinical activity and molecular response (GORTEC 2008-02)

BACKGROUND: Preclinical studies suggest that insulin-like growth factor-1 receptor (IGF-1R) blockage could be a promising therapeutic target in squamous cell carcinoma of the head and neck (SCCHN). Therefore, we investigated the efficacy and toxicity of figitumumab, an anti-IGF-1R monoclonal antibody, in palliative SCCHN. PATIENTS AND METHODS: Patients with palliative SCCHN progressing after platinum-based therapy were treated with figitumumab i.v. 20 mg/kg, every 3 weeks. The primary end point was the disease control rate at 6-8 weeks after treatment initiation. Tumor biopsies and plasma samples were collected before and after figitumumab administration to monitor the molecular response. RESULTS: Seventeen patients were included. Only two patients achieved stable disease at 6-8 weeks. Median overall survival and progression-free survival were 63 and 52 days, respectively. The main grade 3-4 adverse event was hyperglycemia (41%). Translational research showed that figitumumab downregulated IGF-1R at the surface of tumor cells with activation of the epidermal growth factor receptor (EGFR) pathway, as shown by the upregulation of p-EGFR in tumor cells (P = 0.016), and an increase in the plasma level of tumor growth factor-alpha (P = 0.006). CONCLUSION: Figitumumab monotherapy has no clinically significant activity in unselected palliative SCCHN

The use of chemotherapy regimens carrying a moderate or high risk of febrile neutropenia and the corresponding management of febrile neutropenia: an expert survey in breast cancer and non-Hodgkin's lymphoma.

The use of chemotherapy regimens with moderate or high risk of febrile neutropenia (defined as having a FN incidence of 10% or more) and the respective incidence and clinical management of FN in breast cancer and NHL has not been studied in Belgium. The existence of a medical need for G-CSF primary and secondary prophylaxis with these regimens was investigated in a real-life setting. Nine oncologists and six hematologists from different Belgian general hospitals and university centers were surveyed to collect expert opinion and real-life data (year 2007) on the use of chemotherapy regimens with moderate or high risk of febrile neutropenia and the clinical management of FN in patients aged <65 years with breast cancer or NHL. Data were retrospectively obtained, over a 6-month observation period. The most frequently used regimens in breast cancer patients (n = 161) were FEC (45%), FEC-T (37%) and docetaxel alone (6%). In NHL patients (n = 39), R-CHOP-21 (33%) and R-ACVBP-14 (15%) were mainly used. Without G-CSF primary prophylaxis (PP), FN occurred in 31% of breast cancer patients, and 13% had PSN. After G-CSF secondary prophylaxis (SP), 4% experienced further FN events. Only 1 breast cancer patient received PP, and did not experience a severe neutropenic event. Overall, 30% of chemotherapy cycles observed in breast cancer patients were protected by PP/SP. In 10 NHL patients receiving PP, 2 (20%) developed FN, whereas 13 (45%) of the 29 patients without PP developed FN and 3 (10%) PSN. Overall, 55% of chemotherapy cycles observed in NHL patients were protected by PP/SP. Impaired chemotherapy delivery (timing and/or dose) was reported in 40% (breast cancer) and 38% (NHL) of patients developing FN. Based on oncologist expert opinion, hospitalization rates for FN (average length of stay) without and with PP were, respectively, 48% (4.2 days) and 19% (1.5 days). Similar rates were obtained from hematologists. Despite the studied chemotherapy regimens being known to be associated with a moderate or high risk of FN, upfront G-CSF prophylaxis was rarely used. The observed incidence of severe neutropenic events without G-CSF prophylaxis was higher than generally reported in the literature. The impact on medical resources used is sizeable

Cetuximab, docetaxel and cisplatin as first-line treatment in patients with recurrent or metastatic head and neck squamous cell carcinoma: a multicentre, phase II GORTEC study

BACKGROUND: Cetuximab in combination with platinum and 5FU is the standard of care in first-line treatment of patients with recurrent/metastatic head and neck squamous cell carcinoma (HNSCC). Cetuximab and taxane combinations have shown promising activity. This study evaluated the efficacy and safety of four cycles of docetaxel associated with cisplatin and cetuximab (TPEx), followed by maintenance with cetuximab every 2 weeks. PATIENTS AND METHODS: Patients with a histologically confirmed HNSCC with metastasis or recurrence unsuitable for locoregional curative treatment received docetaxel and cisplatin (75 mg/m² both) at day 1 and weekly cetuximab 250 mg/m² (loading dose of 400 mg/m²), repeated every 21 days for 4 cycles, followed by maintenance cetuximab 500 mg/m² every 2 weeks until progression or unacceptable toxicity. Prophylactic administration of G-CSF was done systematically after each chemotherapy cycle. Patients had a good general status (PS≤1) and were under 71 years. Prior total doses of cisplatin exceeding 300 mg/m² were not allowed. The primary endpoint was objective response rate after 4 cycles. RESULTS: Fifty-four patients were enrolled. The primary endpoint was met with an objective response rate of 44.4% (CI 95%: 30.9-58.6). Median overall and progression-free survivals were, respectively, 14 months (CI 95%: 11.3-17.3) and 6.2 months (CI 95%: 5.4-7.2). The most common grade 3/4 adverse events were skin rash (16.6%) and non-febrile neutropenia (20.4%). There were one pulmonary embolism and two infectious events leading to death. CONCLUSIONS: The TPEx regimen showed promising activity as first-line treatment in fit patients with recurrent/metastatic HNSCC. Further studies are needed to compare TPEx vs. EXTREME regimen in this population

Randomized Phase II Study of Cabazitaxel Versus Methotrexate in Patients With Recurrent and/or Metastatic Squamous Cell Carcinoma of the Head and Neck Previously Treated With Platinum-Based Therapy.

LESSONS LEARNED: Cabazitaxel has activity in squamous cell carcinoma of the head and neck (SCCHN) and taxane-resistant cell lines. For the first time, cabazitaxel was investigated in incurable patients with recurrent SCCHN. Patients were randomly assigned to cabazitaxel every 3 weeks or weekly methotrexate.This phase II study did not meet its primary endpoint.Cabazitaxel has low activity in SCCHN.The toxicity profile in this population also was not favorable owing to the high rate of febrile neutropenia observed (17%). BACKGROUND: Cabazitaxel is a second-generation taxane that improves the survival of patients with metastatic castrate-resistant prostate cancer following docetaxel therapy. Cabazitaxel has activity in squamous cell carcinoma of the head and neck (SCCHN) and taxane-resistant cell lines. In this randomized phase II trial, we investigated cabazitaxel in patients with recurrent SCCHN. METHODS: Patients with incurable SCCHN with progression after platinum-based therapy were randomly assigned to cabazitaxel every 3 weeks (cycle 1, 20 mg/m2, increased to 25 mg/m2 for subsequent cycles in the absence of nonhematological adverse events [AEs] greater than grade 2 and hematological AEs greater than grade 3) or methotrexate (40 mg/m2/week). The patients were stratified according to their performance status and previous platinum-based chemotherapy for palliation versus curative intent. The primary endpoint was the progression-free survival rate (PFSR) at 18 weeks. RESULTS: Of the 101 patients, 53 and 48, with a median age of 58.0 years (range, 41-80), were randomly assigned to cabazitaxel or methotrexate, respectively. The PFSR at 18 weeks was 13.2% (95% confidence interval [CI], 5%-25%) for cabazitaxel and 8.3% (95% CI, 2%-20%) for methotrexate. The median progression-free survival was 1.9 months in both arms. The median overall survival was 5.0 and 3.6 months for cabazitaxel and methotrexate, respectively. More patients experienced serious adverse events with cabazitaxel than with methotrexate (54% vs. 36%). The most common drug-related grade 3-4 AE in the cabazitaxel arm was febrile neutropenia (17.3%). CONCLUSION: This study did not meet its primary endpoint. Cabazitaxel has low activity in recurrent SCCHN
