The OVAREX study: Establishment of ex vivo ovarian cancer models to validate innovative therapies and to identify predictive biomarkers.

BACKGROUND: Ovarian cancer is the first cause of death from gynecological malignancies mainly due to development of chemoresistance. Despite the emergence of PARP inhibitors, which have revolutionized the therapeutic management of some of these ovarian cancers, the 5-year overall survival rate remains around 45%. Therefore, it is crucial to develop new therapeutic strategies, to identify predictive biomarkers and to predict the response to treatments. In this context, functional assays based on patient-derived tumor models could constitute helpful and relevant tools for identifying efficient therapies or to guide clinical decision making. METHOD: The OVAREX study is a single-center non-interventional study which aims at investigating the feasibility of establishing in vivo and ex vivo models and testing ex vivo models to predict clinical response of ovarian cancer patients. Patient-Derived Xenografts (PDX) will be established from tumor fragments engrafted subcutaneously into immunocompromised mice. Explants will be generated by slicing tumor tissues and Ascites-Derived Spheroids (ADS) will be isolated following filtration of ascites. Patient-derived tumor organoids (PDTO) will be established after dissociation of tumor tissues or ADS, cell embedding into extracellular matrix and culture in specific medium. Molecular and histological characterizations will be performed to compare tumor of origin and paired models. Response of ex vivo tumor-derived models to conventional chemotherapy and PARP inhibitors will be assessed and compared to results of companion diagnostic test and/or to the patient's response to evaluate their predictive value. DISCUSSION: This clinical study aims at generating PDX and ex vivo models (PDTO, ADS, and explants) from tumors or ascites of ovarian cancer patients who will undergo surgical procedure or paracentesis. We aim at demonstrating the predictive value of ex vivo models for their potential use in routine clinical practice as part of precision medicine, as well as establishing a collection of relevant ovarian cancer models that will be useful for the evaluation of future innovative therapies. TRIAL REGISTRATION: The clinical trial has been validated by local research ethic committee on January 25th 2019 and registered at ClinicalTrials.gov with the identifier NCT03831230 on January 28th 2019, last amendment v4 accepted on July 18, 2023.

Posttraumatic Stress Symptoms in Patients With Cancer During the COVID-19 Pandemic: A One-Year Longitudinal Study.

BACKGROUND: Patients with cancer may be particularly vulnerable to psychological consequences of the COVID-19 pandemic. We studied the prevalence and evolution of posttraumatic stress symptoms (PTSS) in patients with cancer during the pandemic waves, and we investigated factors associated with high symptoms. METHODS: COVIPACT is a 1-year longitudinal prospective study of French patients with solid/hematologic malignancies receiving treatment during the first nationwide lockdown. PTSS were measured every 3 months from April 2020 using the Impact of Event Scale-Revised. Patients also completed questionnaires on their quality of life, cognitive complaints, insomnia, and COVID-19 lockdown experience. RESULTS: Longitudinal analyses involved 386 patients with at least one PTSS assessment after baseline (median age, 63 years; 76% female). Among them, 21.5% had moderate/severe PTSS during the first lockdown. The rate of patients reporting PTSS decreased at lockdown release (13.6%), increased again at second lockdown (23.2%), and slightly declined from the second release period (22.7%) to the third lockdown (17.5%). Patients were grouped into 3 trajectories of evolution. Most patients had stable low symptoms throughout the period, 6% had high baseline symptoms slowly decreasing over time, and 17.6% had moderate symptoms worsening during the second lockdown. Female sex, feeling socially isolated, worrying about COVID-19 infection, and using psychotropic drugs were associated with PTSS. PTSS were associated with impaired quality of life, sleep, and cognition. CONCLUSIONS: Approximately one-fourth of patients with cancer experienced high and persistent PTSS over the first year of the COVID-19 pandemic and may benefit from psychological support.

Head and neck cancer patients under radiotherapy undergoing skin application of hydrogel dressing or hyaluronic acid: results from a prospective, randomized study.

PURPOSE: Acute radiodermatitis (ARD) is a frequent side effect of radiotherapy, a therapeutic option for head and neck squamous cell carcinoma (HNSCC). It is responsible for pain, quality of life (QoL) impairment, and increased risk of treatment discontinuation, which may compromise the prognosis for patients. Local therapies to prevent or alleviate ARD have been proposed without providing any high level of evidence to establish recommendations. METHODS: We implemented a prospective multicenter randomized study on patients with HNSCC treated with definitive radiotherapy to assess the impact on ear, nose, and throat (ENT) pain of the application of a hydrogel-based skin dressing (HydroTac®) compared with the application of hyaluronic acid (Ialuset®) during radiotherapy. RESULTS: Out of 130 enrolled patients, 48 patients per group were assessable for the main endpoint. No difference between groups was found: a worsening of ENT pain of 3 points or more on a visual analog scale from the initiation to 1 month after the end of the radiotherapy was observed for 8 patients (16.7%) who received HydroTac® compared to 13 patients (27%) who received Ialuset® (p = 0.342). The proportion of patients who experienced ARD and grades of ARD (CTCAE v4.0 criteria) were similar between groups. Patient compliance with radiodermatitis treatment was poor, with 56.1% of patients in the HydroTac® group having their treatment temporarily stopped. CONCLUSION: The application of a hydrogel dressing to prevent ARD during radiotherapy for HNSCC patients has failed to demonstrate a benefit. These results may be limited by the difficulties of applying the dressing.

Cognitive assessment in patients treated by immunotherapy: the prospective Cog-Immuno trial.

BACKGROUND: The discovery of the importance of the immune system and its role in oncogenesis led to the development of immunotherapy, a treatment that represents a major advance in oncology management. Due to the recent nature of immunotherapy, little is known about its side effects and their impact on quality of life. To date, there is no published study that accurately assesses the impact of immunotherapy on cognition, mood and/or fatigue in patients treated for cancer, despite potential neurological toxicities. The purpose of this study is to prospectively assess the incidence of cognitive impairment and cognitive complaints among cancer patients naïve for immunotherapy without concomitant anti-cancer treatment. METHODS: The Cog-Immuno trial is a multicentre longitudinal study addressing patients with cancer candidate to receive immunotherapy alone (n = 100). Immunotherapy treatment will include either anti-PD1/PDL1 or anti-CTLA4 monotherapy or combination therapy. Cognitive and quality of life assessment, electrocardiogram (ECG) and biological tests will be performed at baseline, thereafter 3, and 6 months after immunotherapy initiation. The primary endpoint is the proportion of patients treated by immunotherapy who will experience a decline in cognitive performances or in Montreal Cognitive Assessment (MoCA) score within 3 months after inclusion. Secondary endpoints concern: anxiety, depression, fatigue, clinical characteristics, biological data and neurophysiological measures (heart rate variability and hemispheric lateralization). A pre-clinical study will be conducted in cancer bearing mice receiving checkpoint inhibitors (ICI) with the evaluation of cognitive functions and emotional reactivity, collection of blood samples and investigation of neurobiological mechanisms from brain slices. DISCUSSION: Assessing and understanding the incidence and the severity of cognitive impairment and its impact on quality of life in cancer patients treated by immunotherapy is a major issue. The results of this study will provide information on the impact of these treatments on cognitive functions in order to help the physicians in the choice of the treatment.

Perioperative treatment in resectable gastric cancer with spartalizumab in combination with fluorouracil, leucovorin, oxaliplatin and docetaxel (FLOT): a phase II study (GASPAR).

BACKGROUND: Perioperative chemotherapy and surgery are a standard of care for patients with resectable gastric or gastroesophageal junction (GEJ) adenocarcinoma. However, the prognosis remains poor for this population. The FLOT (fluorouracil, leucovorin, oxaliplatin, and docetaxel) regimen is considered as the new standard chemotherapy regimen for perioperative strategy, despite associated with a 5-year overall survival rate (OS) amounting 45% following radical surgery. Immunotherapy with antibodies that inhibit PD-1/ PD-L1 interaction has recently emerged as a new treatment option with promising and encouraging early trial results for patients with advanced or metastatic gastric or GEJ adenocarcinoma. Currently, no trials have investigated the impact of perioperative immunotherapy in combination with chemotherapy for resectable gastric or GEJ adenocarcinoma. METHODS: GASPAR trial is a multicenter open-label, nonrandomized, phase II trial to evaluate the efficacy and safety of Spartalizumab in combination with the FLOT regimen as perioperative treatment for resectable gastric or GEJ adenocarcinoma. The main endpoint is the proportion of patients with pathological complete regression (pCR) in the primary tumour after preoperative treatment. Systemic treatment will include a pre-operative neoadjuvant and a post-operative adjuvant treatment, during which FLOT regimen will be administered every two weeks for 4 cycles and Spartalizumab every four weeks for 2 cycles. For patients with confirmed tumor resectability on imaging assessment, surgery will be realized within 4-6 weeks after the last dose of preoperative chemotherapy. Post-operative systemic treatment will then be initiated within 4-10 weeks after surgery. Using a Simon's two-stage design, up to 67 patients will be enrolled, including 23 in the first stage. DISCUSSION: Currently, no trials have investigated the impact of immunotherapy in combination with FLOT chemotherapy as perioperative treatment for resectable gastric or GEJ adenocarcinoma. Some studies have suggested a change in the tumor immune micro-environment following neoadjuvant chemotherapy in this setting, reinforcing the relevance to propose a phase II trial evaluating efficacy and safety of Spartalizumab in combination with perioperative chemotherapy, with the aim of improving treatment efficacy and survival outcomes.

A phase II study of Navitoclax (ABT-263) as single agent in women heavily pretreated for recurrent epithelial ovarian cancer: The MONAVI - GINECO study.

BACKGROUND: There are limited treatment options for ovarian cancer patients with early relapse after platinum chemotherapy. In preclinical studies, we previously demonstrated the promising activity of ABT-737, a Bcl-2/Bcl-xL anti-apoptotic protein inhibitor, in chemo-resistant ovarian cancer cells and tumors, suggesting its potential activity in platinum-resistant patients. METHODS: We conducted a prospective multicenter single-arm phase II study to assess the efficacy of Navitoclax (orally available ABT-737 analogue) monotherapy in 46 heavily pretreated (2-12 lines, median = 4) patients with high-grade serous platinum-resistant ovarian tumors. Navitoclax was administered at the daily dose of 150 mg during a lead-in period (7-14 days) and then increased to 250 mg daily in the absence of dose-limiting thrombocytopenia (

Impact of adjuvant trastuzumab treatment on fatigue, emotional status and quality of personal and work life of patients with localised breast cancer: results of the 'HER-ception' study.

PURPOSE: The aim of this study was to analyse the impact of adjuvant trastuzumab on fatigue, emotional status, and quality of personal and work life of patients treated for localised breast cancer. METHODS: In a prospective setting, we recruited age-matched localised breast cancer patients, treated by adjuvant chemotherapy with (group 1) or without IV trastuzumab (group 2), between September 2011 and May 2014. Patients completed questionnaires on quality of life (FACT-G, FACT-B), fatigue (FACIT-F, ICQ), anxiety-depression (HADS), and work life (dedicated self-questionnaire) at inclusion then at 3, 6, 9, and 15 months. RESULTS: We included 35 patients in each group. No significant difference was found between the two groups concerning return to work, fatigue, and quality of life scores at each phase of the study. In total, 39 patients (72.2%) reported having returned to work at T15, with no significant difference between the two groups (p = 0.53). Significantly higher scores for'helplessness' outcomes were observed in group 1, 9, and 15 months (6.138 and 5.731; p = 0.047 and 0.048, respectively). Patients in group 1 reported higher score of anxiety-depression than group 2 at 3 months (p = 0.027) then no significant difference was observed at the other times of the study. CONCLUSION: Trastuzumab does not appear to affect fatigue and return to work in patients with localised breast cancer. The emotional well-being could be affected in patients treated by trastuzumab, with a more pronounced 'helplessness' feeling which could be more related to the additional follow-up imposed by the prescription of trastuzumab.

Cancer Pain and Patient Education: Strategy, Implementation, Difficulties and Opportunities of EFFADOL, a Regional Collaborative Programme.

While pain remains a burden for many cancer patients, their active involvement in dealing with it through therapeutic patient education (TPE) has proved effective in overcoming hurdles to pain management. This article describes how a regional TPE programme devoted to cancer pain was set up, as well as the difficulties and opportunities encountered during its implementation. Ten nurse-doctor pairs from the chronic pain units of Lower Normandy, after being trained in TPE, designed and built the EFFADOL (Ensemble Faire Face A la DOuLeur [Cope together with pain]) programme. They collaboratively developed the pedagogical, evaluation and communication tools used in the programme. After the educational diagnosis step, patients are able to follow three sessions in order to acquire the following skills: (1) understanding the different types of pain, (2) understanding pain treatments and their adverse reactions and (3) optimally managing pain on a daily basis. Patients can ask a relative to join the sessions and can choose their preferred modality (individual and/or collective sessions). Programme implementation and the importance of communicating with oncologists and independent health professionals are discussed. The programme, which is available to patients close to home, meets their needs as previously assessed through a regional prospective survey. Difficulties to include patients and opportunities to address them are identified. The programme's limitations mainly concern its organization, structure and communication issues. The main challenge remains the overhaul of care practices and the role of the caregiver to allow patient autonomy.

Post-traumatic stress symptomatology and adjustment of medical oncology practice during the COVID-19 pandemic among adult patients with cancer in a day care hospital.

BACKGROUND: The COVID-19 pandemic may induce post-traumatic stress disorder (PTSD) symptoms among patients with cancer, who also face adaptations to their treatment. The authors assessed the occurrence of PTSD symptoms, investigated pandemic-induced adjustments in medical oncology practice in patients with cancer, and explored risk factors for PTSD and the association between PTSD symptoms, insomnia, and quality of life (QoL). METHODS: This prospective French study was conducted in patients with solid/hematologic tumors who were receiving medical treatment in the day care departments of 2 cancer centers during the lockdown. Adjustments to medical oncology practice were collected from medical records. PTSD (measured using the Impact of Event Scale-Revised), insomnia (measured using the Insomnia Severity Index), QoL (measured using the Functional Assessment of Cancer Therapy-General instrument), and cognitive complaints (measured using the Functional Assessment of Cancer Therapy-Cognitive Function instrument) were collected through validated questionnaires. RESULTS: Clinical data and questionnaires were available for 734 and 576 patients, respectively. The median patient age was 64 years, and 69% of patients were women. Twenty-one percent of patients had PTSD. Twenty-seven percent (95% CI, 23%-30%) had an adjustment in their medical oncology program, including adjournments (29%), treatment interruptions (16%), modified treatment plans (27%), or adapted monitoring (27%). Women and patients experiencing an adjustment in oncology practice had a higher odds of PTSD (odds ratio= 2.10 [95% CI, 1.07-4.14] and 1.65 [95% CI, 1.03-2.63]; P < .05). PTSD symptoms were correlated with worse scores for QoL, cognition, and insomnia. CONCLUSIONS: Twenty-one percent of patients with cancer experienced PTSD symptoms associated with poor QoL during the first COVID-19-induced lockdown. Medical oncology practice was adjusted in approximately one-quarter of patients and was associated with the occurrence of PTSD symptoms. Psychosocial support should be offered in cancer centers to promote emotional resilience and avoid PTSD symptoms in patients.

CABOCOL-01 trial: a single-arm phase II study assessing safety and efficacy of Cabozantinib for advanced or metastatic cervical carcinoma after platinum treatment failure.

BACKGROUND: Cervical cancer is the tenth diagnosed cancer in the world. Early-stage and locally recurrent disease may be cured with radical surgery or chemo-radiotherapy. However, if disease persists or recurs, options are limited and the prognosis is poor. In addition to chemotherapy, bevacizumab, an antiangiogenic agent, has recently demonstrated its efficacy in this setting. Cabozantinib is an oral small molecule tyrosine kinase inhibitor that exhibits potent inhibitory activity against several receptor tyrosine kinases that are known to influence tumor growth, metastasis, and angiogenesis. The main targets of Cabozantinib are VEGFR2, MET and AXL. It is currently approved for the treatment of metastatic renal cell carcinoma, hepatocellular carcinoma and medullary thyroid carcinoma. Given its angiogenic properties associated with growth factor receptors inhibition, Cabozantinib represents a potential active treatment in cervical carcinoma. In this context, we propose to assess the efficacy and safety of cabozantinib monotherapy in advanced/metastatic cervical carcinoma (CC) after failure to platinum-based regimen treatment. METHODS: This study is a single-arm two-stage multicenter phase II aiming to simultaneously assess efficacy and safety of Cabozantinib among advanced/metastatic cervical carcinoma (CC) after failure to platinum-based regimen treatment. The main criterion will be based on both safety and clinical efficacy by conducting a Bryant-and-Day design. Safety endpoint is the proportion of patients with clinical gastro-intestinal (GI) perforation/fistula, GI-vaginal fistula and genito-urinary (GU) fistula events grade ≥ 2 (NCI CTCAE V.5.0) occurring up to one month after the end of treatment. Efficacy endpoint is the proportion of patients with disease control rate 3 months after Cabozantinib initiation. A patients' self-reported quality of life evaluation is also planned, as well as the investigation of nutritional outcomes. Cabozantinib will be administered at the daily dose of 60 mg given orally, without interruption until disease progression or discontinuation for any cause. DISCUSSION: Cabozantinib is a promising drug for patients with advanced/metastatic cervical cancer where few therapeutics options are available after failure to platinum-based regimen metastatic CC. It appears challenging to assess the interest of Cabozantinib in this indication, taking into account the potential toxicity of the drug. TRIAL REGISTRATION: NCT04205799 , registered "2019 12 19".

Stereotactic radiotherapy on brain metastases with recent hemorrhagic signal: STEREO-HBM, a two-step phase 2 trial.

BACKGROUND: Brain metastases often occur in cancer evolution. They are not only responsible for death but also for disorders affecting the quality of life and the cognitive functions. Management of brain metastases usually consists in multi-modality treatments, including neurosurgery, whole brain radiotherapy (WBRT), and more recently radiosurgery (SRS) or fractionated stereotactic radiotherapy (FSRT), systemic treatment (chemotherapy or targeted therapy), combined or not with corticosteroids. Almost 20% of brain metastases can present recent (within 15 days) bleeding signs on neuro-imagery. In these conditions, WBRT is the usual treatment. Yet, patients may benefit from a more aggressive strategy with SRT or FSRT. However, these options were suspected to possibly major the risk of brain haemorrhage, although no scientifically proven. Radiation oncologists therefore usually remain reluctant to deliver SRS/FSRT for bleeding brain metastases. It is therefore challenging to establish a standard of care for the treatment of bleeding brain metastases. We propose a phase II trial to simultaneously assess safety and efficacy of FSRT to manage brain metastases with hemorrhagic signal. METHODS: The STEREO-HBM study is a multicenter two-step non-randomised phase II trial addressing patients with at least one bleeding brain metastasis out of a maximum of 3 brain metastases. Each brain metastasis will be treated with 30 Gy in 3 fractions for 1 week. The main endpoint is based on both safety and efficacy endpoints as proposed by Bryant and Day's design. Safety endpoint is defined as the rate of bleeding complications 4 months post-FSRT while efficacy endpoint is defined as the 6-month local control rate. Multi-modal MRI will be used to assess intra-tumoral hemorrhagic events before and after treatment. Patients' quality of life will also be assessed. DISCUSSION: Management of bleeding brain metastases is still debated and poorly explored in clinical trials. There is sparse and weak data on the signification of pretreatment intra-tumour haemorrhagic signs or on the risk of brain bleeding complications after FSRT. We expect this first prospective phase 2 trial in this particular setting will allow to clarify the place of FSRT to optimally manage bleeding brain metastases.

Cognitive Changes After Adjuvant Treatment in Older Adults with Early-Stage Breast Cancer.

BACKGROUND: Group-based trajectory modeling is particularly important to identify subgroups of patients with pathological cognitive changes after cancer treatment. To date, only one study has explored cognitive trajectories in older patients with cancer. The present article describes objective cognitive changes before to after adjuvant treatment in older adults with early-stage breast cancer (EBC) after adjuvant treatment compared with healthy controls. PATIENTS AND METHODS: Participants were patients ≥65 years of age with newly diagnosed EBC and healthy controls (age-, sex-, and education-matched). The pretreatment assessment was conducted before adjuvant therapy, and the post-treatment assessment after the end of the first adjuvant treatment. Objective cognitive changes before to after treatment were evaluated based on the Reliable Change Index for cognitive decline accounting for cognitive impairment status. RESULTS: The sample consisted of women newly diagnosed with EBC (n = 118) and healthy controls (n = 62). Five patterns of changes before to after treatment were identified based on the presence of cognitive decline and cognitive impairment. The distribution of these five change patterns was statistically significant (p = .0001). Thirty-six percent of patients had phase shift changes, 31% without initial objective cognitive impairment developed impairment, 15% had a normal aging, 12% had a nonpathological decline, and 6% experienced accelerated cognitive decline. CONCLUSION: This study described for the first time objective cognitive changes before to after treatment of older adults with EBC immediately after the end of adjuvant treatment. A longer-term remote follow-up of adjuvant treatment is needed to better understand the cognitive trajectories of older patients with EBC. IMPLICATIONS FOR PRACTICE: After the end of adjuvant treatment, 31% of older adults with early-stage breast cancer without initial objective cognitive impairment developed impairment, and 6% experienced accelerated cognitive decline. Initial cognitive functioning should be included in the balance of benefits and harms of systemic therapy for patients who are likely to be at highest risk for cognitive decline after cancer treatments. Regular cognitive follow-up of patients who had cognitive impairment before cancer treatment should monitor symptoms suggestive of neurodegenerative disease and avert the effect of cognitive disorders on patients' autonomy.

Effectiveness of a therapeutic patient education program in improving cancer pain management: EFFADOL, a stepped-wedge randomised controlled trial.

BACKGROUND: Despite numerous guidelines, nearly one of two patients with cancer pain remains undertreated, thereby affecting their quality of life. Active patient involvement through Therapeutic Patient Education (TPE) is considered as a relevant strategy to overcoming hurdles in pain management. The aim of the EFFADOL study is to assess the effectiveness of a TPE program in improving cancer pain management. METHODS/DESIGN: The EFFADOL study is a stepped-wedge randomised controlled trial. A total of 260 cancer patients with unbalanced background pain will be randomised over the institutional level, i.e. stepped-wedge cluster design. Six clusters will be formed, one at the regional level of "Basse-Normandie" for patients receiving the educational approach by health providers already trained to TPE. Then, five additional centers will be gradually included at the national level, making it possible to compare the "conventional" management of pain (before medical staff training to TPE) with the educational approach (after being trained). The main study parameter is pain interference on daily life assessed with the self-administrated and validated Brief Pain Inventory questionnaire. Secondary objectives comprised the evaluation of patients' adherence to pain education program, the description of pain intensity, pain relief, analgesic adherence and pain emotional impact. Educational dimension of the program will be evaluated through the patients' acquisition of knowledge and skills about their pain and treatment as well as their self-efficacy to participate actively in pain management. The patient's feeling of pain changes will be measured. Finally, the satisfaction of participants and educators will be reported. We hypothetise active involvement of patients in TPE will lead to an improved pain management compared to standard care. DISCUSSION: Analyzing the impact of a TPE program in cancer pain patients will improve their pain management and quality of life. We expect that the dissemination of our project educational approach through the French territory will be accompanied by long term change in clinical practices with mutual benefit to patients and caregiver-educators.

Phase I/IIa study of concomitant radiotherapy with olaparib and temozolomide in unresectable or partially resectable glioblastoma: OLA-TMZ-RTE-01 trial protocol.

BACKGROUND: Despite multimodality treatments including neurosurgery, radiotherapy and chemotherapy, glioblastoma (GBM) prognosis remains poor. GBM is classically considered as a radioresistant tumor, because of its high local recurrence rate, inside the irradiation field. The development of new radiosensitizer is crucial to improve the patient outcomes. Pre-clinical data showed that Poly (ADP-ribose) polymerase inhibitors (PARPi) could be considered as a promising class of radiosensitizer. The aim of this study is to evaluate Olaparib, a PARPi, as radiosensitizing agent, combined with the Stupp protocol, namely temozolomide (TMZ) and intensity modulated radiotherapy (IMRT) in first line treatment of partially or non-resected GBM. METHODS: The OLA-TMZ-RTE-01 study is a multicenter non-randomized phase I/IIa trial including unresectable or partially resectable GBM patients, from 18 to 70 years old. A two-step dose-escalation phase I design will first determine the recommended phase 2 dose (RP2D) of olaparib, delivered concomitantly with TMZ plus conventional irradiation for 6 weeks and as single agent for 4 weeks (radiotherapy period), and second, the RP2D of olaparib combined with adjuvant TMZ (maintenance period). Phase IIa will assess the 18-month overall survival (OS) of this combination. In both phase I and IIa separately considered, the progression-free survival, the objective response rate, the neurocognitive functions of patients, emotional disorders among caregivers, the survival without toxicity, degradation nor progression, the complications onset and the morphologic and functional MRI (magnetic resonance imaging) parameters will be also assessed as secondary objectives. Ancillary objectives will explore alteration of the DNA repair pathways on biopsy tumor, proton magnetic resonance spectroscopy parameters to differentiate tumor relapse and radionecrosis, and an expanded cognition evaluation. Up to 79 patients will be enrolled: 30 patients in the phase I and 49 patients in the phase IIa. DISCUSSION: Combining PARP inhibitors, such as olaparib, with radiotherapy and chemotherapy in GBM may improve survival outcomes, while sparing healthy tissue and preserving neurocognitive function, given the replication-dependent efficacy of olaparib, and the increased PARP expression in GBM as compared to non-neoplastic brain tissue. Ancillary studies will help to identify genetic biomarkers predictive of PARPi efficacy as radiosensitizer. TRIAL REGISTRATION: NCT03212742 , registered June, 7, 2017.

Therapeutic Patient Education in Cancer Pain Management: from Practice to Research: Proposals and Strategy of the French EFFADOL Program.

In the field of cancer pain, therapeutic patient education (TPE) allows patients to develop skills to better manage their pain. In the Lower Normandy region of France, the management of pain is based on networking, thus allowing proximity and accessibility for all concerned. We have thus designed and initiated a broad five-stage research program that includes the following: (1) training for caregivers in TPE; (2) identifying the educational expectations of patients and their relatives with regard to cancer pain; (3) the design of a TPE program; (4) the evaluation of its quality; and (5) the evaluation of its effectiveness by comparative randomization. This article presents this approach and more particularly the research phases (stages 2, 4, 5) for which the objectives, the methodology, and the expected results are justified. Among the key points, particular attention is paid to the evaluation of the educational dimension that provides patients with self-efficacy to participate actively in the management of their pain, their perception of changes in relation to it and its impact. The choice of a specific assessment criterion (subscale 9 of the Brief Pain Inventory) and of the step-wedge design are thus argued. This approach, which is based on a partnership between health care professionals and researchers, aims to demonstrate the benefits provided by TPE to patients in order to enable them to better manage their pain on a daily basis.

Impact of new generation hormone-therapy on cognitive function in elderly patients treated for a metastatic prostate cancer: Cog-Pro trial protocol.

BACKGROUND: New generation hormone-therapies (NGHT) targeting the androgen signalling pathway are nowadays proposed to elderly patients with metastatic castration-resistant prostate cancer (CRPCa). The impact of these treatments on cognitive function has never been evaluated whereas cognitive impairment may have an impact on the autonomy and the treatment adherence. The aim of this study is to prospectively assess the incidence of cognitive impairment in elderly men after treatment by NGHT for a metastatic CRPCa. METHODS/DESIGN: The Cog-Pro study is a multicentre longitudinal study including CRPCa patients ≥70 years old treated with NGHT (n = 134), control metastatic prostate cancer patients without castration resistance treated with first generation androgen deprivation therapy (n = 55), and healthy participants (n = 33), matched on age and education. Cognitive, geriatric and quality of life assessment and biological tests will be performed at baseline, 3, 6 and 12 months after start of the treatment (inclusion time). The primary endpoint is the proportion of elderly patients receiving a NGHT who will experience a decline in cognitive performances within 3 months after study enrollment. Secondary endpoints concern: autonomy, quality of life, anxiety, depression, cognitive reserve, adherence to hormone-therapy, comparison of the cognitive impact of 2 different NGHT (abiraterone acetate and enzalutamide), impact of co-morbidities and biological assessments. DISCUSSION: Evaluating, understanding and analyzing the incidence, severity of cognitive impairments and their impact on quality of life, autonomy and adherence in this group of patients with advanced disease is a challenge. This study should help to improve cancer care of elderly patients and secure the use of oral treatments as the risk of non-observance does exist. Our results will provide up-to date information for patients and caregivers on impact of these treatments on cognitive function in order to help the physicians in the choice of the treatment.

Clinical benefits of non-taxane chemotherapies in unselected patients with symptomatic metastatic castration-resistant prostate cancer after docetaxel: the GETUG-P02 study.

OBJECTIVE: To evaluate the overall benefits of non-taxane chemotherapies in a non-selected population including unfit patients presenting with symptoms and pain. PATIENTS AND METHODS: This randomized phase II study reports data from 92 patients (52% >70 years old; 40% with a performance score of 2) previously treated with taxane-based chemotherapy, collected from 15 centres in France. Patients received i.v. mitoxantrone (MTX), oral vinorelbine, or oral etoposide, together with oral prednisone. Palliative benefit (pain response without progression of the disease), biological and tumoural responses, and toxicity profile as well as geriatric assessment (in elderly population) were analysed on an intention-to-treat basis. RESULTS: The palliative response rate was 17% for the whole population, and reached 29% when considering the MTX arm. Pain control was achieved in 40% of the patients. The median overall survival was 10.4 months, and was longer in palliative responders. Few grade 3-4 toxicities were observed. The subgroup analysis of elderly patients showed similar results regarding the number and dose intensity of treatments, efficacy and safety. CONCLUSION: In a population including frail and/or elderly patients, who are poorly represented in most clinical studies, non-taxane chemotherapy may remain a relevant option for metastatic prostate cancer having relapsed after a docetaxel-based regimen. Although new treatment options are now approved, the decision-making process should take into account their expected benefit/risk ratio based on the patient status.

Carboplatin in metastatic castration-resistant prostate cancer patients with molecular alterations of the DNA damage repair pathway: the PRO-CARBO phase II trial.

Introduction: DNA damage repair genes are altered in 20-35% of metastatic castration-resistant prostate cancer (mCRPC). Poly-ADP (Adénosine Diphosphate)-ribose polymerase inhibitors (PARPi) showed significant activity for these selected tumors, especially with homologous recombination repair (HRR) deficiency. These alterations could also predict platinum sensitivity. Although carboplatin was inconclusive in unselected mCRPC, the literature suggests an anti-tumoral activity in mCRPC with HHR gene alterations. We aimed to assess the efficacy of carboplatin monotherapy in mCRPC patients with HRR deficiency. Methods: This prospective multicenter single-arm two-stage phase II addressed mCRPC men with HRR somatic and/or germline alterations, pretreated with ⩾2 taxane chemotherapy regimens and one androgen receptor pathway inhibitor. Prior PARPi treatment was allowed. Enrolled patients received intravenous carboplatin (AUC5) every 21 days for 6-9 cycles. The primary endpoint was the best response rate according to adapted PCWG3 guidelines: radiological response (RECIST 1.1 criteria) and/or biological response [⩾50% prostate-specific antigen (PSA) decline]. Results: A total of 15 out of 16 enrolled patients started carboplatin treatment. Genomic alterations were identified for BRCA2 (n = 5), CDK12 (n = 3), ATM (n = 3) CHEK2 (n = 2), CHEK1 (n = 1), and BRCA1 (n = 1) genes. Objective response (partial biological response + stable radiological response) was achieved in one patient (6.7%), carrying a BRCA2 mutation and not pre-treated with PARPi; stable disease was observed for five patients (33.5%). Among seven patients (46.7%) with previous PARPi treatment, four patients (57.1%) had a stable disease. The median progression-free and overall survivals were 1.9 [95% confidence interval (95% CI), 1.8-9.5] and 8.6 months (95% CI, 4.3-19.5), respectively. The most common severe (grade 3-4) treatment-related toxicities were thrombocytopenia (66.7%), anemia (66.7%), and nausea (60%). Overall, 8 (53.3%) patients experienced a severe hematological event. Conclusion: The study was prematurely stopped as pre-planned considering the limited activity of carboplatin monotherapy in heavily pre-treated, HHR-deficient mCRPC patients. Larger experience is needed in mCRPC with BRCA alterations. Trial registration: NCT03652493, EudraCT ID number 2017-004764-35.

Shared Meditation Involving Cancer Patients, Health Professionals and Third Persons: Perceptions of Participants Through a Focus Group Study.

People with cancer often experience psychological distress and in addition, the practice of oncology is one of the most stressful areas of medicine for health professionals. Mindfulness meditation has been used to alleviate stress-related symptoms. We therefore ran a pilot study to assess the feasibility of a mindfulness intervention involving cancer patients, health professionals, and third persons together, as part of a comprehensive project aiming to evaluate the added value of 'meditating together'. Following on from our quantitative analyses of the project, we investigated its qualitative aspects through focus groups to explore the perceptions of participants regarding their experience. Focus groups conducted in 7 patients, 7 health professionals, and 8 third persons after the intervention showed that 'meditating together' was generally appreciated, particularly by patients, who found it motivating and a way to relieve their feelings of loneliness in the face of illness. All participants reported better stress management. They also shared benefits and difficulties concerning the practice of meditation and the programme's modalities. In addition, they all stated that the programme should be lasting. The opinion of the patients (our target population) will be decisive in building an optimized programme that will suit them the best. In conclusion, the protocol and the qualitative findings of the present study validate the rationale for conducting a fully powered randomized trial to demonstrate the potential added value of shared meditation and how it improves well-being by promoting bridge-building between cancer patients, health professionals and others.Trial Registration: ClinicalTrials.gov.
