[The nurse at the heart of the assistance system for outpatients in the post-cancer period]. / L'infirmière au cœur du dispositif d'assistance des malades ambulatoires dans l'après-cancer.

An innovative approach to post-treatment follow-up of lymphoma, Ambulatory Cancer Assistance (ACA) is a model of care shared between a general practitioner, a hematologist and a nurse coordinator. The role of the nurse coordinator is preponderant in this type of follow-up, which appears to be more effective in detecting medical, psychological and social events than standard follow-up. The AMA-AC helps patients return to their pre-cancer life.

Sustained degradation of quality of life in a subgroup of lymphoma survivors: a two-year prospective survey.

BACKGROUND: Previous studies have suggested that lymphoma survivors commonly display altered Health-Related Quality of Life (HRQoL). Because these were predominantly cross-sectional studies, the dynamic of events as well as the factors which influence HRQoL remain to be determined. METHODS: We conducted a prospective study on a cohort of 204 Hodgkin and non-Hodgkin lymphoma survivors who remained disease-free 2 years after undergoing chemotherapy (referred to the M0-M12-M24 periods). RESULTS: We found that although Physical and Mental Component Scores (PCS and MCS) of HRQoL significantly improved from M0 to M24 in the vast majority of patients (favorable group), approximately 20% of patients displayed severe alterations in HRQoL (global SF-36 scores < 50) extending over the 2-year period (unfavorable group). Low M24 PCSs were associated with Post-Traumatic Stress Disorder (PTSD), depression, cardiovascular events and neuropathy. In contrast social determinants, comorbidity and infections, as well as several other parameters related to the disease or to the treatment itself were not associated with low M24 PCSs. Low M24 MCSs were associated with a low educational level, aggressive histology, infections, cardiovascular events and PTSS. However, the most predictive risk factor for low SF-36 scores at M24 was a low SF-36 score at M12. The unfavorable group also displayed a low incidence of return to work. CONCLUSIONS: Although the HRQoL of lymphoma survivors generally improved over time, persistent and severe HRQoL alterations still affected approximately one fifth of patients, resulting in important social consequences. This specific group, which presents with identifiable risk factors, may benefit from early, targeted psycho-social support.

Oncology nurse phone calls halve the risk of reduced dose intensity of immunochemotherapy: results of the randomized FORTIS study in chronic lymphocytic leukemia.

Delivering of > 80% planned relative dose intensity (RDI) of fludarabine-cyclophosphamide-rituximab (FCR) is key to benefit from longer progression free survival (PFS) and survivals in CLL. In this randomized trial, we sought to investigate whether a telephone intervention strategy (called AMA) delivered by an oncology nurse could reduce the risk of RDI < 80% by alleviating adverse events and supporting patients' adherence. Sixty FCR patients were randomized 1:1 for AMA (stratified on Binet stage C). As per guidelines, patients received pegfilgrastim as primary prophylaxis of febrile neutropenia. At the end of therapy, RDI < 80% was reported in 31% of patients, shortening PFS (median 26 months versus not reached, P = 0.021) and OS at 3 years (100 vs 70%, P = 0.0089). Oncology nurse interventions tended to significantly reduce this event (RDI < 80%: 41.4% in non-AMA versus 20.7% in AMA patients (p = 0.09)). By adjusting our logistic regression model on published parameters exposing to RDI < 80%, we found that AMA protected significantly against the risk of reduced RDI (OR = 0.22, IC95% 0.05-0.84, p = 0.04), independently of grade 3/4 neutropenia (< 15% per cycle) and febrile neutropenia (< 5% per cycle) events. As a conclusion, we confirmed that > 20% reduction of FCR dose-intensity was detrimental for PFS/OS, but that oncology nurse interventions reduced the risk of dose concessions.

[Nursing expertise and assistance for patients in ambulatory care in haemato-oncology]. / Expertise infirmière et assistance des malades ambulatoires en oncohématologie.

An innovative programme to assist outpatients aims to improve the support provided to patients being treated for cancer in the context of their community-hospital care pathway. Evaluated in haematology with patients receiving treatment for lymphoma, leukaemia, including allografts, the programme highlights new nursing roles at the heart of patient follow-up care. The safety and fluidity of the patient pathway is improved and the medical time optimised.

Ambulatory Medical Assistance--After Cancer (AMA-AC): A model for an early trajectory survivorship survey of lymphoma patients treated with anthracycline-based chemotherapy.

BACKGROUND: Cancer survivorship has emerged as an important aspect of oncology due to the possibility of physical and psychosocial complications. The purpose of this study was to assess the feasibility of the Ambulatory Medical Assistance for After Cancer (AMA-AC) procedure for monitoring lymphoma survivorship during the first year after chemotherapy. METHODS: AMA-AC is based on systematic general practitioner (GP) consultations and telephone interventions conducted by a nurse coordinator (NC) affiliated to the oncology unit, while an oncologist acts only on demand. Patients are regularly monitored for physical, psychological and social events, as well as their health-related quality of life (HRQoL). Inclusion criteria were patients newly diagnosed with non-Hodgkin or Hodgkin lymphomas, who had been treated with anthracycline-based chemotherapy and were in complete remission after treatment. RESULTS: All 115 patients and 113 collaborating GPs agreed to participate in the study. For patients who achieved one year of disease-free survival (n = 104) their assessments (438 in total) were fully completed. Eleven were excluded from analysis (9 relapses and 2 deaths). The most frequent complications when taking into account all grades were arthralgia (64.3%) and infections (41.7%). About one third of patients developed new diseases with cardiovascular complications as the most common. Psychological disorders such as anxiety, depression and post-traumatic stress disorder were diagnosed in 42.6% of patients. The data collected showed that Hodgkin lymphoma patients, females, and patients with lower HRQoL (mental component) at study entry were at greater risk for developing at least one psychological disorder. CONCLUSION: This study showed that AMA-AC is a feasible and efficient procedure for monitoring lymphoma survivorship in terms of GP and patient participation rates and adherence, and provides a high quality of operable data. Hence, the AMA-AC procedure may be transferable into clinical daily practice as an alternative to standard oncologist-based follow-up.

A longitudinal study of non-medical determinants of adherence to R-CHOP therapy for diffuse large B-cell lymphoma: implication for survival.

BACKGROUND: Adherence to therapy has been established for years as a critical parameter for clinical benefit in medical oncology. This study aimed to assess, in the current practice, the influence of the socio-demographical characteristics and the place of treatment on treatment adherence and overall survival among diffuse large B-cell lymphoma patients. METHODS: We analysed data from 380 patients enrolled in a French multi-centre regional cohort, with diffuse large B-cell lymphoma receiving first-line treatment with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) or R-CHOP-like regimens. Direct examination of administrative and medical records yielded the date of death. We studied the influence of patients' socio-demographic characteristics and place of treatment on the treatment adherence and overall survival, adjusted for baseline clinical characteristics. Treatment adherence was measured by the ratio between received and planned dose Intensity (DI), called relative DI (RDI) categorized in "lesser than 85%" and "at least 85%". RESULTS: During the follow-up, among the final sample 70 patients had RDI lesser than 85% and 94 deceased. Multivariate models showed that advanced age, poor international prognosis index (IPI) and treatment with R-CHOP 14 favoured RDI lesser than 85%. The treatment in a public academic centre favoured RDI greater than or equal to 85%. Poor adherence to treatment was strongly associated with poor overall survival whereas being treated in private centres was linked to better overall survival, after adjusting for confounders. No socioeconomic gradient was found on both adherence to treatment and overall survival. CONCLUSIONS: These results reinforce adherence to treatment as a critical parameter for clinical benefit among diffuse large B-cell lymphoma patients under R-CHOP. The place of treatment, but not the socioeconomic status of these patients, impacted both RDI and overall survival.

Impact of dose intensity on outcome of fludarabine, cyclophosphamide, and rituximab regimen given in the first-line therapy for chronic lymphocytic leukemia.

Fludarabine-cyclophosphamide-rituximab is the most efficient first-line treatment for chronic lymphocytic leukemia patients. Many dose adjustments of the original MD Anderson Cancer Center regimen have been proposed. However, whether fludarabine-cyclophosphamide-rituximab relative dose intensity may have an impact on outcome has not yet been investigated. We retrospectively assessed relative dose intensity in 106 community-based patients included in our regional healthcare network from 2004-11, all receiving fludarabine-cyclophosphamide-rituximab as first-line treatment outside clinical trials. Dose reductions were observed in 51.4% of patients, mainly decided by the individual physician and not based on recommendations (52.7%), while there were fewer reports of toxicity or dose reduction because of impaired renal function. Progression-free survival was significantly reduced in patients who had a reduction in dose intensity of more than 20% in fludarabine-cyclophosphamide and/or rituximab. Multivariate analysis showed dose of rituximab had a significant impact on minimal residual disease and progression-free survival. Although prophylactic granulocyte-colony stimulating factor significantly reduced the rate of grade 3-4 neutropenia and febrile neutropenia, it had no impact on relative dose intensity and outcome. This study shows that, in routine clinical practice, there is low adherence to the original MD Anderson Cancer Center fludarabine-cyclophosphamide-rituximab schedule, and that the decision to modify dosage was mostly taken by the individual physician and was based on anticipated toxicity. This study shows that reduction of fludarabine-cyclophosphamide and, more importantly, of rituximab doses seriously interferes with progression-free survival.

Posttraumatic Stress Disorder Symptoms in Lymphoma Patients: A Prospective Study.

The cancer experience may be marked by repeat stressors and/or traumas. The aim of our study was to assess traumatic events in a group of patients diagnosed with lymphoma and to determine which of these contribute to the development of Post-Traumatic Stress Disorder/PTSD. Two weeks after receiving a diagnosis of lymphoma, patients were referred for an assessment of peritraumatic distress (using the Peritraumatic Distress Inventory/PDI) and peritraumatic dissociation (using the Peritraumatic Dissociative Experiences Questionnaire/PDEQ). Three months after the diagnosis, we recorded the following parameters: the patients' worst experiences, the presence of PTSD symptoms, using the PTSD CheckList/PCL, as it related to the diagnosis, and symptoms of anxiety using the Hospital Anxiety and Depression/HAD scale and of depression using the Beck Depression Inventory/BDI-II. The study recruited 129 patients, with a mean age of 46 years (SD = 17.3); 70 (54%) men, 87 (67.5%) with Non-Hodgkin's lymphoma, and 42 with Hodgkin's lymphoma. Two weeks after the diagnosis, 49% of patients reported peritraumatic distress, and 20% peritraumatic dissociation, during or immediately after being informed of the lymphoma diagnosis. Three months after the diagnosis, the severity of PTSD symptoms was evaluated. At this stage none of the patients suffered PTSD, but 29 (23%) individuals exhibited partial PTSD: 13.4% correlated it to receiving the lymphoma diagnosis, 8% to telling family members, and 1.6% to adverse effects. Peritraumatic distress and dissociation as a result of receiving a lymphoma diagnosis, as well as anxiety and a mucositis within the first 3 months post-diagnosis, were factors that were significantly associated with PTSD symptoms, accounting for 35.8% in PTSD symptom load. Our study reveals that clinicians should assess the impact of a number of stressors, which are risk factors for PTSD symptoms, starting from the time point of the initial lymphoma diagnosis.

Effectiveness of telephone support during chemotherapy in patients with diffuse large B cell lymphoma: the Ambulatory Medical Assistance (AMA) experience.

BACKGROUND: During chemotherapy, patients experience disabling side effects or even sometimes life-threatening treatment-related complications, contributing to poor quality of life, reduced therapeutic compliance, decreased relative dose-intensity, and ultimately poorer outcomes. OBJECTIVES: The Ambulatory Medical Assistance (AMA) project, a monitoring procedure based on a standardized telephone intervention, was aimed to improve ambulatory care quality in aggressive B-cell lymphomas treated with standard front-line R-CHOP therapy. DESIGN: Non-comparative prospective study. SETTING AND PARTICIPANTS: Over a three-years period, one hundred diffuse large B cell lymphoma (DLBCL) patients were treated in a single hospital and monitored in an ambulatory setting through planned telephone interventions delivered by a single nurse under the supervision of an oncologist. METHODS: In addition to biological monitoring, patients received a bi-weekly telephone call from an oncology-certified nurse. All events were recorded on a call form, which was forwarded to a supervisor oncologist. Nurse calls resulted in one of the following: no intervention, grade 1 intervention based on a pre-established protocol managed by the nurse under oncologist supervision, or grade 2 intervention related to more severe complications, managed directly by the oncologist, and mostly resulting in secondary hospitalization. RESULTS: The AMA procedure consisted of 3592 phone calls (600 h) resulting in 989 interventions (27.5%). Grade 1 intervention represented 950 cases whereas grade 2 intervention was noted in only 39 cases (3.9%). AMA also appeared to improve medical management. Indeed, compared to the literature, we observed lower incidence in secondary hospitalization (6%), delayed treatment (6%), reduced relative dose-intensity (RDI) (no patient with RDI<80%), toxic death (0%), and red blood cell transfusion (13%). CONCLUSIONS: AMA appears to improve R-CHOP therapy management. However, comparative studies are needed to demonstrate the advantage of the AMA over standard management, in terms of therapeutic compliance, progression-free survival, and medico-economics efficacy.
