[Needs assessment for the establishment of an Oral Therapy Unit]. / Évaluation des besoins pour la mise en place d'une Unité de Thérapie Orale.

INTRODUCTION: Oncological at home-treatment improves patient quality of life and autonomy but requires close watchfulness of adverse events and compliance to treatment. For nearly ten years, pharmaceutical consultations for home-based anticancer oral therapies patients are proposed on medical request in Avignon-Provence Cancer Institute (ICAP). Organizational changes led us to modify this management by integrating dedicated nurses to create an Oral Therapy Unit (OTU). MATERIALS ET METHODS: Needs and expectations assessment questionnaires were proposed to healthcare professionals and patients treated by oral therapies. The analysis of these questionnaires allows to set up an OTU, integrating a dedicated nurse, adapted to the expectations of patients and healthcare professionals. About 8 months later, a new evaluation was carried out to assess the impact of this new support for patient care and health professionals' organization. RESULTS: The results of the studies carried out before OTU implementation highlight the importance of multi-professional support for patients from the start of treatment and during the follow-up. With the new OTU pathway, professionals expect a patient course improvement (94%), a better compliance (88%), a therapeutic accidents reduction (81%) and an improvement in the patient-caregiver relationship (69%). Regarding the organization, 56% of them are expecting to save medical and pharmaceutical time. CONCLUSION: The OTU creation in our institution and these new multi-professionals' teams' management of patients has obtained a favourable opinion from healthcare professionals and patient satisfaction.

Genomics to select treatment for patients with metastatic breast cancer.

Cancer progression is driven in part by genomic alterations1. The genomic characterization of cancers has shown interpatient heterogeneity regarding driver alterations2, leading to the concept that generation of genomic profiling in patients with cancer could allow the selection of effective therapies3,4. Although DNA sequencing has been implemented in practice, it remains unclear how to use its results. A total of 1,462 patients with HER2-non-overexpressing metastatic breast cancer were enroled to receive genomic profiling in the SAFIR02-BREAST trial. Two hundred and thirty-eight of these patients were randomized in two trials (nos. NCT02299999 and NCT03386162) comparing the efficacy of maintenance treatment5 with a targeted therapy matched to genomic alteration. Targeted therapies matched to genomics improves progression-free survival when genomic alterations are classified as level I/II according to the ESMO Scale for Clinical Actionability of Molecular Targets (ESCAT)6 (adjusted hazards ratio (HR): 0.41, 90% confidence interval (CI): 0.27-0.61, P < 0.001), but not when alterations are unselected using ESCAT (adjusted HR: 0.77, 95% CI: 0.56-1.06, P = 0.109). No improvement in progression-free survival was observed in the targeted therapies arm (unadjusted HR: 1.15, 95% CI: 0.76-1.75) for patients presenting with ESCAT alteration beyond level I/II. Patients with germline BRCA1/2 mutations (n = 49) derived high benefit from olaparib (gBRCA1: HR = 0.36, 90% CI: 0.14-0.89; gBRCA2: HR = 0.37, 90% CI: 0.17-0.78). This trial provides evidence that the treatment decision led by genomics should be driven by a framework of target actionability in patients with metastatic breast cancer.

Quality assurance program and early toxicities in the phase III BONBIS randomized trial evaluating the role of a localized radiation boost in ductal carcinoma in situ.

PURPOSE: To describe the quality assurance (QA) program and early toxicities in the phase III randomized trial BONBIS (NCT00907868) on the role of a localized radiation boost in ductal carcinoma in situ (DCIS). MATERIALS AND METHODS: From November 2008 to July 2014, 2004 patients were randomized in arm A (only whole breast radiotherapy, WBRT) and arm B (WBRT + boost). The QA program involved 44 participant centers that performed the dummy run (DR). Compliance and uniformity of clinical target volume (CTV) delineations, and dose prescription and delivery according to the BONBIS trial radiotherapy guidelines were analyzed. Acute toxicities (during and up to 3 months after radiotherapy completion, NCI-CTCAE v3.0 classification) were evaluated in 1929 patients. RESULTS: The differences in whole breast CTV (CTV1) and planning target volume (PTV1) were ≤10%, and the differences in boost CTV (CTV2) and PTV (PTV2) were ≥20% compared with the reference DR values; 95% of the prescribed dose encompassed 98.7% and 100% of the median CTV1 and CTV2. Grade ≥2 breast erythema (38.3% vs. 22.4% of grade 2 and 5.4% vs. 2.1% of grade 3, p < 0.001), grade ≥2 dermatitis (2.8% vs. 0.7%, p < 0.001), and grade 2 hyperpigmentation (6.9% vs. 3.6%, p = 0.005) were more frequent in arm B than arm A. No acute lung or cardiac toxicity was observed. Smoking history, large breast size, and large breast CTV were strong predictive factors of grade ≥2 acute skin toxicities. CONCLUSIONS: The QA program showed deviations in breast and tumor bed delineation. The boost significantly increased acute skin toxicities.

Durvalumab compared to maintenance chemotherapy in metastatic breast cancer: the randomized phase II SAFIR02-BREAST IMMUNO trial.

The impact of single-agent antibodies against programmed death-ligand 1 (PD-L1) as maintenance therapy is unknown in patients with metastatic breast cancer. The SAFIR02-BREAST IMMUNO substudy included patients with human epidermal growth factor receptor type 2 (Her2)-negative metastatic breast cancer whose disease did not progress after six to eight cycles of chemotherapy. Patients (n = 199) were randomized to either durvalumab (10 mg kg-1 every 2 weeks) or maintenance chemotherapy. In the overall population, durvalumab did not improve progression-free survival (adjusted hazard ratio (HR): 1.40, 95% confidence interval (CI): 1.00-1.96; P = 0.047) or overall survival (OS; adjusted HR: 0.84, 95% CI: 0.54-1.29; P = 0.423). In an exploratory subgroup analysis, durvalumab improved OS in patients with triple-negative breast cancer (TNBC; n = 82; HR: 0.54, 95% CI: 0.30-0.97, P = 0.0377). Exploratory analysis showed that the HR of death was 0.37 (95% CI: 0.12-1.13) for patients with PD-L1+ TNBC (n = 32) and 0.49 (95% CI: 0.18-1.34) for those with PD-L1- TNBC (n = 29). In patients with TNBC, exploratory analyses showed that the HR for durvalumab efficacy (OS) was 0.18 (95% CI: 0.05-0.71; log-rank test, P = 0.0059) in patients with CD274 gain/amplification (n = 23) and 1.12 (95% CI: 0.42-2.99; log-rank test, P = 0.8139) in patients with CD274 normal/loss (n = 32). Tumor infiltration by lymphocytes (CD8, FoxP3 and CD103 expressions) and homologous recombination deficiency did not predict sensitivity to durvalumab in exploratory analyses. This latter finding should be interpreted with caution since only one patient presented a germline BRCA mutation. The present study provides a rationale to evaluate single-agent durvalumab in maintenance therapy in patients with TNBC. Exploratory analyses identified CD274 amplification as a potential biomarker of sensitivity. Maintenance chemotherapy was more effective than durvalumab in patients with hormone receptor-positive and Her2-negative disease.

Role of supportive care in improving the quality of life and reducing unscheduled hospital care in patients with metastatic breast cancer.

BACKGROUND: Metastatic breast cancer (MBC) patients experience long survival and report poorer quality of life than localized breast cancer patients. Comprehensive supportive care (CSC) has been shown to improve the quality of life (QoL) of MBC. The respective part of each support care has not been fully examined, and little is known about whether meeting patients' needs is accompanied by decreased unscheduled hospital care (UHC). METHODS: This prospective monocentric study included women who started a new treatment line for MBC between January 2018 and December 2018. The endpoints were factors associated with UHC and QoL (SF36) at month 12. RESULTS: 100 patients were offered CSC, 78 were included (21 refusals, 1 no MBC). CSC was provided to 60 patients: pain (43%), psychological (37%), kinesitherapy (30%), social assistance (22%), esthetic (18%), nutrition (18%), massage (13%), and none (10%). CSC rate was not statistically different among patients with (58%) and without UHD (49%). Factors associated with a decrease of UHC were age > 65 years (p = 0.01), no previous treatment for MBC (p = 0.0001) with a trend for the lack of CSC (p = 0.054). Among the 8 domains of the SF36 scale, only health change perception was improved (p = 0.01) and its predictive factors were treatment carried out as planned (p = 0.0004), pain care (p = 0.003), and lack of MBC progression (p = 0.0035). CONCLUSION: CSC can improve QoL in MBC. Painful patients might benefit more from CSC. UHC did not decrease for patients receiving CSC as expected possibly because of their important needs for clinical care.

Ductal Carcinoma in Situ: A French National Survey. Analysis of 2125 Patients.

BACKGROUND: Ductal carcinoma in situ (DCIS) represents 15% of all breast cancers in France. The first national survey was conducted in 2003. The present multi-center real-life practice survey aimed at assessing possible changes in demographic, clinical, pathologic, and treatment features. MATERIAL AND METHODS: From March 2014 to September 2015, patients diagnosed with DCIS from 71 centers with complete information about age, diagnostic features, and treatment modalities were prospectively included. RESULTS: A total of 2125 patients with a median age of 58.6 years from 71 centers were studied. DCIS was diagnosed by mammography in 87.5% of cases. Preoperative biopsy was performed in 96% of cases. The median tumor size was 15 mm. Nuclear grade was low, intermediate, and high in 12%, 36%, and 47% of cases, respectively. Margins were considered to be negative in 83% of cases. Overall mastectomy and lumpectomy rates were 25% and 75%, respectively. The immediate breast reconstruction rate was 50%. Sentinel node biopsy and axillary dissection rates were 41% and 2.6%, respectively. After lumpectomy, 97% of patients underwent radiotherapy, and 32% received a boost dose. Only 1% of patients received endocrine therapy. Compared with our previous survey, the median tumor size remained the same, and the proportion of high-grade lesions increased by 9%. The mastectomy rate decreased by 4%. CONCLUSIONS: The clinical practice identified in this survey complies with French DCIS guidelines. About 10% of patients with low-grade DCIS may be eligible to participate in treatment de-escalation trials.

["SOS SEIN 84" accelerated breast disease management: Patients satisfaction survey]. / « SOS SEIN 84 ¼ prise en charge rapide en pathologie mammaire : enquête de satisfaction des consultantes.

In case of a new breast symptom or an abnormal result of breast imaging, some women have a problem finding a quick answer to allay their anxiety. The Institut Sainte-Catherine in Avignon has set up a new form of accelerated disease management through the opening of a new dedicated consultation called SOS SEIN 84. We present the result of a prospective quality study of our first new patients.

[Methods of development of recommendations for clinical practice (RCP) and of setting-up of a platform cancer heart vessels (PTF-CHV) in the inter3C Vaucluse-Arles]. / Méthodes d'élaboration des recommandations pour la pratique clinique (RPC) et fonctionnement de la plate forme cœur vaisseaux cancer (PTF-CVC) dans l'inter3C Vaucluse pays d'Arles.

Monitoring and prevention of cardiovascular complications of anti-neoplastic treatment are currently well known for anthracyclines and trastuzumab but remain poorly implemented. The management of cardiac and vascular side effects of targeted therapies is not codified. The purpose of the platform heart-vessel cancer is to optimize the management of such complications within a small area (Vaucluse region of Arles). The platform will offer prescribers an easily accessible database, doctors performing exams standardized monitoring forms and patients a uniform follow-up. We report here the methodology of the elaboration of recommendations for clinical practice and the ways to develop the platform. After a year of active process, an analysis of the will be performed to see opportunities for improvement and dissemination on a larger scale.

Breast cancer occurred after Hodgkin's disease: clinico-pathological features, treatments and outcome: analysis of 214 cases.

BACKGROUND: Secondary tumours (ST) represent a major concern in survivors of Hodgkin's disease (HD). Breast cancer (BC) is the most frequent ST among young treated women. MATERIAL AND METHODS: One hundred and eighty-nine women treated for HD by radiotherapy (RT) and/or chemotherapy (CT) subsequently developed 214 BCs. RESULTS: Median age at HD diagnosis was 25 years (34% were less than 20). Median interval between HD and BC was 18.6 years, with a 42-year median age at first BC. According to the TNM classification, there were 30 (14%) T0 (non palbable lesions), 86 (40%) T1, 56 (26%) T2, 13 (6%) T3T4 and 29 (14%) Tx. There were 25 (13.2%) contralateral BC. 160 (75%) and 15 (7%) tumours were infiltrating ductal and lobular carcinomas, 7 (3.3%) were other subtypes and 27 (22%) DCIS. The rate of axillary nodal involvement was 32%. Among 203 operated tumours, 79 (39%) were treated by breast conserving surgery (BCS), with RT in 56 (71%) cases. CT and hormonal treatment were delivered in 51% and 45% of the patients. With a 50-month median follow-up, local recurrence occurred in 12% of the tumours (9% after mastectomy, 21% after lumpectomy alone and 13.7% after lumpectomy with RT). Metastasis occurred in 47 (26%) patients. The risk factors were pN+, pT, high SBR grade and young age (< 50 years). The ten-year overall and specific survival rates were 53% and 63.5%, respectively. The ten-year specific survival rates were 79% for pT0T1T2, 48% for pT3T4 (p = 0.0002) and 79% for pN0 versus 38.5% for pN+ (p = 0.00026). Among 67 deaths, 43 (73%) were due to BC. CONCLUSION: Patients and physicians should be aware that BC is the most frequent secondary tumour in young women treated for HD. The new RT modalities (lower doses and involved fields) may decrease the risk in the future. However, these women require a careful monitoring as from 8 to 10 years after HD treatment, combining mammography, ultrasound and MRI according to several ongoing studies. BC with whole breast irradiation is feasible in some selected cases.

Impact of intensity-modulated radiotherapy on health-related quality of life for head and neck cancer patients: matched-pair comparison with conventional radiotherapy.

PURPOSE: To assess the benefit of intensity-modulated radiotherapy (IMRT) compared with conventional RT for the quality of life (QOL) of head and neck cancer survivors. METHODS AND MATERIALS: Cross-sectional QOL measures (European Organization for Research and Treatment of Cancer QOL questionnaire C30 and head and neck cancer module) were used with a French multicenter cohort of patients cured of head and neck cancer (follow-up > or = 1 year) who had received bilateral neck RT (> or = 45 Gy) as a part of their initial treatment. We compared the QOL mean scores regarding RT modality (conventional RT vs. IMRT). The patients of the two groups were matched (one to one) according to the delay between the end of RT and the timing of the QOL evaluation and the T stage. Each QOL item was divided into two relevant levels of severity: "not severe" (responses, "not at all" and "a little") vs. "severe" (responses "quite a bit" and "very much"). The association between the type of RT and the prevalence of severe symptoms was approximated, through multivariate analysis using the prevalence odds ratio. RESULTS: Two comparable groups (67 pairs) were available. Better scores were observed on the head and neck cancer module QOL questionnaire for the IMRT group, especially for dry mouth and sticky saliva (p < 0.0001). Severe symptoms were more frequent with conventional RT concerning saliva modifications and oral discomfort. The adjusted prevalence odds ratios were 3.17 (p = 0.04) for dry mouth, 3.16 (p = 0.02) for sticky saliva, 3.58 (p = 0.02) for pain in the mouth, 3.35 (p = 0.04) for pain in the jaw, 2.60 (p = 0.02) for difficulties opening the mouth, 2.76 (p = 0.02) for difficulties with swallowing, and 2.68 (p = 0.03) for trouble with eating. CONCLUSION: The QOL assessment of head and neck cancer survivors demonstrated the benefit of IMRT, particularly in the areas of salivary dysfunction and oral discomfort.

Radiotherapy for solitary extramedullary plasmacytoma in the head-and-neck region: A dose greater than 45 Gy to the target volume improves the local control.

PURPOSE: Our aim was to determine the dose to the clinical target volume (CTV) required for solitary extramedullary plasmacytoma (EMP) in the head and neck (HN). METHODS AND MATERIALS: Seventeen patients (15 Stage I and 2 Stage II) were treated for HN EMP at our institution between 1979 and 2003. The mean International Commission on Radiation Units (ICRU) dose prescribed to the CTV was 52.6 Gy (range, 40-65 Gy) over 24 fractions (range: 20-30). The Stage II patients received neck irradiation doses of 40 and 60 Gy. A mean dose of 36.4 Gy was used for 5 Stage I patients who received elective neck irradiation. Dose administrated to the CTV was evaluated from dosimetric data or from planning films when dosimetric data were not available. Two groups of patients were distinguished: CTV covered with a dose greater than 40 Gy and CTV covered with a dose greater than 45 Gy. RESULTS: The 5-year local control was 72.8%. It was 100% for patients who received dose to the CTV > or = [DOSAGE ERROR CORRECTED] 45 Gy vs. 50% for dose to the CTV <45 Gy (p = 0.034). The prognostic factor for 5-year disease-specific survival (81.6%) was local control (p = 0.058). The prognostic factors for disease-free survival (64.1%) were monoclonal immunoglobulin secretion (p = 0.008) and a CTV dose > or = 45 Gy (p = 0.056) CONCLUSIONS: Local control of EMP in the HN seems to be improved when the dose to the CTV is > or = [DOSAGE ERROR CORRECTED] 45 Gy. A minimum dose of 45 Gy should be recommended to the CTV.
