Improving Adherence to Adjuvant Endocrine Therapy in Breast Cancer Through a Therapeutic Educational Approach: A Feasibility Study
.

PURPOSE/OBJECTIVES: To develop and test the feasibility of a tailored therapeutic educational program, with the aim of improving adherence to oral endocrine adjuvant chemotherapy in women with breast cancer. 
. DESIGN: A qualitative study to identify educational needs and a feasibility study assessing the efficacy of the program.
. SETTING: A comprehensive cancer center, the Lucien Neuwirth Cancer Institute in Saint-Priest-en-Jarez, France.
. SAMPLE: Two consecutive samples (N = 11, N = 6) of women taking adjuvant oral endocrine chemotherapy for breast cancer. 
. METHODS: A mixed qualitative and quantitative method was used. The participants' representations of disease and treatment were explored through one-on-one interviews and then translated into educational needs, which were used to develop a tailored therapeutic education program. The pilot study evaluated the reach and efficacy using before-and-after comparisons. 
. MAIN RESEARCH VARIABLES: Educational objectives, knowledge, trust in the treatment, and anxiety.
. FINDINGS: Five educational objectives (acquiring knowledge, improving communication skills, managing anxiety, managing side effects, and improving adherence) were identified through 11 interviews. A three-session program was developed. Eight of the 23 patients invited to participate in a pilot study accepted, and six completed the intervention. Knowledge improved from 38.9 of 100 preintervention to 69.4 of 100 postintervention (p = 0.045). Trust in treatment showed a trend to improvement from 5.5 of 10 to 8 of 10 (p = 0.14), but anxiety did not change significantly; anxiety went from 6 to 7 (p = 0.88).
. CONCLUSIONS: Results from the feasibility study showed promising efficacy for the educational objectives and provided information about how the program could be improved. 
. IMPLICATIONS FOR NURSING: Tailored educational programs conducted by trained nurses may help patients to adhere to and live with the effects of endocrine therapy.

Uterine and ovary carcinosarcomas: outcome, prognosis factors, and adjuvant therapy.

OBJECTIVES: The aim of this study was to assess the outcome and the prognosis factors of uterine and ovarian carcinosarcomas. METHODS: From January 1993 to January 2010, data from 68 consecutively treated patients with uterine (n=59) and ovarian (n=9) carcinosarcomas were retrospectively analyzed in a single French comprehensive cancer center. RESULTS: The median follow-up was 24.2 months (interquartile range [IQR]: 13.5 to 54.6). The median age was 69 years (IQR: 63 to 77). Patients were classified as FIGO stage I (n=28; 41%) and FIGO stage II to IV (n=40; 59%), respectively. There were 33 (49%) and 29 (43%) homologous and heterologous type, respectively. The median disease-free survival and overall survival were 21.9 months (IQR: 7.9 to 22.3) and 27.1 months (IQR: 14.5 to 72), respectively. No statistical differences of survival were reported concerning the initial location of the carcinosarcoma (uterine vs. ovarian). Radiation therapy (hazards ratio [HR]=0.3; 95% confidence interval [CI], 0.16-0.67) and FIGO stage I (HR=0.4; 95% CI, 0.17-0.9) were associated with an increased disease-free survival. Homologous type (HR=3; 95% CI, 1.4-6.3) and FIGO stage II to IV (HR=2.64; 95% CI, 1.3-5.4) were associated with a decreased overall survival. There was no survival improvement for the 12% of patients receiving a multimodal adjuvant therapy. CONCLUSIONS: Uterine and ovary carcinosarcomas present a worse prognosis. On the basis of the present study data, although it should be prospectively confirmed, a sequential or multimodal adjuvant therapy should be proposed to patients with early-stage uterine and ovary carcinosarcomas.

Pharmacogenetic tailoring of irinotecan-based first-line chemotherapy in metastatic colorectal cancer: results of a pilot study.

BACKGROUND: Tolerability to irinotecan may be explained by pharmacogenomic polymorphisms. The purpose of this pharmacogenetic trial was to study the relevance of thymidylate synthase (TS) genotyping and of the isoform 1A1 of uridine diphosphate glucuronosyltransferase (UGT1A1) in order to tailor a combination chemotherapy regimen of 5-fluorouracil, leucovorin and irinotecan (FOLFIRI) in metastatic colorectal cancer. PATIENTS AND METHODS: Patients with favourable TS and UGT1A1 profiles received high-dose (HD) FOLFIRI. Patients with TS-3R/3R could not receive HD-FOLFIRI, and those with UGT1A1-7/7 received standard FOLFIRI. The endpoints were overall response rate and safety. RESULTS: Sixty-nine patients were enrolled in the study. Sixty-five patients received chemotherapy. Twenty patients (30.8%) achieved a partial response. The haematological toxicity was less in the HD-FOLFIRI subgroup. Patients having received HD-FOLFIRI did not experience increased levels of nausea-vomiting, asthenia or alopecia. Diarrhoea was more frequent with HD-FOLFIRI. CONCLUSION: The genotypic assessment allowed a safer use of HD-FOLFIRI. Further investigations may target patients who benefit from intensification.

High-dose irinotecan plus LV5FU2 or simplified LV5FU (HD-FOLFIRI) for patients with untreated metastatic colorectal cancer: a new way to allow resection of liver metastases?

UNLABELLED: The antitumor efficacy of irinotecan may be dose dependent. This study aimed to determine the safety and efficacy of high-dose (HD) irinotecan combined with LV5FU2 or simplified LV5FU (LV5FUs) in first-line treatment of metastatic colorectal cancer. PATIENTS AND METHODS: Patients with unresectable and measurable metastatic colorectal cancer, not pretreated for metastatic disease, were given irinotecan 260 mg/m(2) combined with LV5FU2 in the first 25 patients, then with LV5FUs (HD-FOLFIRI) in 35 patients. G-CSF was given in case of febrile neutropenia, grade 4 neutropenia >7 days or neutropenia grade >1 at day 15. RESULTS: The response rate was 57% (95% confidence interval 43-69%). Second surgery with curative intent was performed in 28% of patients, leading to 20% radiological complete response. Median response duration, time to progression and overall survival were 11, 9 and 22 months, respectively. The median dose intensity of irinotecan was 117 mg/m(2)/week. G-CSF was given to 45% of patients over 33% of cycles. Usual toxicity of irinotecan and 5-FU were observed without major increased frequency, except hematological toxicity. Tolerance was similar with LV5FU2 and LV5FUs, though more asymptomatic grade 3-4 neutropenia was observed with LV5FU2. CONCLUSION: HD-irinotecan plus LV5FU2 or HD-FOLFIRI is feasible and achieved a high response rate and postsurgery complete response rate.

Inflammatory breast cancer outcome with epirubicin-based induction and maintenance chemotherapy: ten-year results from the French Adjuvant Study Group GETIS 02 Trial.

BACKGROUND: The authors evaluated the long-term efficacy and side effects in patients with nonmetastatic, unilateral, inflammatory breast cancer (IBC) who received homogeneous treatment with intensive induction chemotherapy followed by a maintenance regimen. METHODS: One hundred twenty patients were randomized to receive high-dose fluorouracil, epirubicin, and cyclophosphamide (FEC-HD) (fluorouracil 750 mg/m(2) on Days 1 to 4, epirubicin 35 mg/m(2) on Days 2 to 4, and cyclophosphamide 400 mg/m(2) on Days 2 to 4 for 4 cycles every 21 days) with or without lenograstim. Locoregional treatment consisted of surgery and/or radiotherapy. Maintenance chemotherapy was FEC 75 (fluorouracil 500 mg/m(2), epirubicin 75 mg/m(2), and cyclophosphamide 500 mg/m(2) on Day 1 every 21 days for 4 cycles). No hormone treatment was allowed. RESULTS: The safety of the FEC-HD regimen was described previously. Among 102 patients who underwent surgery, a pathologic complete response (pCR) was achieved by 23.5% of patients with breast tumors and by 31.4% of patients with involved axillary lymph nodes. The overall pCR rate was 14.7%. One hundred nine patients received FEC 75. After a median 10 years of follow-up, the disease-free survival (DFS) and overall survival (OS) rates were 35.7% and 41.2%, respectively. The median DFS was 39 months (95% confidence interval [95% CI], 25-53 months), and the median survival was 61 months (95% CI, 43-79 months). Five patients developed a temporary decrease in left ventricular ejection fraction without congestive heart failure. In the lenograstim group, 1 patient developed acute myeloblastic leukemia M2, and 1 patient developed myelodysplastic syndrome. CONCLUSIONS: FEC-HD induction chemotherapy followed by FEC 75 maintenance regimen had moderate and acute long-term toxicities and lead to high DFS and OS rates in patients with IBC.

Clinical and economic impact of epoetin in adjuvant-chemotherapy for breast cancer.

INTRODUCTION: Anaemia is a common toxicity in cancer patients and epoetins (EPOs) are now an established treatment. The economic profile of EPO treatment was assessed in patients with breast cancer treated by adjuvant-chemotherapy. MATERIALS AND METHODS: Two strategies were compared: without treatment by EPO and with the possible use of treatment by EPO (epoetin alfa) when required. The clinical effectiveness criterion was time adjusted to quality of life and economic data included only direct medical costs. MAIN RESULTS: One hundred ninety-two patients were included. In the group with the strategy containing the possible use of EPO, 45.5% of patients effectively received EPO. A significant difference in the haemoglobin level profile over time was observed which provided a significant overall benefit of 0.0052 (p<10(-4)) quality-adjusted life year (QALY) associated with an extra cost of 1,615 (p<10(-4)). In the base case analysis, the cost per added QALY was estimated as 310,577 with the strategy containing the possible use of EPO. CONCLUSION: This robust result seems to be unacceptable, but the only relevant point of discussion might be the level of acceptable incremental cost-effectiveness ratio (ICER) for a patient.
