RESUMEN

Background: Currently, the long-term prognosis and survival rate of patients with high-grade glial tumors remains poor and there are no biomarkers. hPG80 (circulating progastrin) secreted into the blood by tumor cells has been widely studied in colorectal cancer. Its involvement in tumorigenesis has been demonstrated in the literature. Moreover, according to a recent study, hPG80 is expressed in the blood of cancer patients at a significantly higher concentration than in the control group composed of healthy blood donors. Methods: The PROGLIO study is a pilot, single-center, longitudinal study that primarily seeks to evaluate circulating plasma hPG80 concentrations over time in patients with high-grade glial tumors. A fasting blood sample will be taken on the start and end day of radiotherapy and during the adjuvant chemotherapy (every 3 cycles). Follow-up monitoring will be performed for 9 months, with a blood sample taken every 3 months on the day of the follow-up MRI. The study plans to recruit 30 patients and recruitment started in February 2022. Trial registration: ClinicalTrials.gov, ID NCT05157594; registered on October 27, 2021.

RESUMEN

PURPOSE: The proportion of older populations living with cancer is on the increase. Maintaining or improving their quality of life (QoL) has become an important goal in the treatment of cancer and has become an endpoint in clinical trials. Melatonin regulates a wide variety of physiological functions and is involved in the initiation of sleep and the improvement of QoL. With age, the secretion of melatonin decreases and could lead to a deterioration in QoL. METHODS: Literature searches were conducted using the PubMed database. The search terms and derivatives of "metastatic cancer", "older patients", "quality of life" and "melatonin" were used. Titles and abstracts were screened to identify whether studies were relevant for full-text screening. RESULTS: There is major concern about the symptoms older cancer patients encounter during treatment because they can impact their QoL. Melatonin supplementation presents several benefits for older patients: improvement in survival, decrease in symptoms induced by cancer and cancer treatment, and also improvements in quality of life. CONCLUSION: It therefore seems appropriate to study the impact of melatonin supplementation during cytotoxic therapy on QoL among elderly patients with metastatic cancer. The use of melatonin as a therapeutic strategy seems particularly suitable for elderly patients, a population known to secrete significantly less melatonin. However, to date, no studies have been conducted in this population.

RESUMEN

Introduction: Patient-derived xenografts (PDX) can be used to explore tumour pathophysiology and could be useful to better understand therapeutic response in breast cancer. PDX from mammary tumours are usually made from metastatic tumours. Thus, PDX from primitive mammary tumours or after neoadjuvant treatment are still rare. This study aims to assess the feasibility to establish xenografts from tumour samples of patients with triple negative or luminal B breast cancer in neoadjuvant, adjuvant or metastatic setting. Methods: XENOBREAST is a single-centre and prospective study. This feasibility pilot trial aims to produce xenografts from tumour samples of patients with triple negative or luminal B breast cancer. Patient enrolment is expected to take 3 years: 85 patients will be enrolled and followed for 28 months. Additional blood samples will be taken as part of the study. Surgical specimens from post-NAC surgery, primary surgery or surgical excision of the metastases will be collected to establish PDX. Histomolecular characteristics of the established PDX will be investigated and compared with the initial histomolecular profile of the collected tumours to ensure that they are well-established. Ethics and dissemination: XENOBREAST belongs to category 2 interventional research on the human person. This study has been approved by the Sud Méditerranée IV - Montpellier ethics committee. It is conducted notably in accordance with the Declaration of Helsinki and General Data Protection Regulation (GDPR). Study data and findings will be published in peer-reviewed medical journals. We also plan to present the study and all data at national congresses and conferences. Registration: ClinicalTrials.gov ID NCT04133077; registered on October 21, 2019.

RESUMEN

Physical activity is known to prevent the occurrence of cancer and decrease the risk of breast cancer. At diagnosis of breast cancer, fewer than half of the patients reach the international recommendation for physical activity. However, breast cancer patients, and particularly HER2+ breast cancer patients, are exposed to treatment-induced cardiotoxicity because of a side effect of 2 molecules used in standard therapy to treat these tumors, i.e., anthracycline and trastuzumab. Cardiotoxicity can sometimes lead to discontinuation of the treatment and even to the development of cardiovascular diseases. Exercise is known to protect the cardiovascular system in the healthy population. Consequently, being physically active during treatment appears to be a way to prevent the negative impact of cancer treatment on the heart in this population. In particular, aerobic exercising could have a protective effect against treatment-induced cardiotoxicity. A supervised physical activity program seems to be the best way for breast cancer patients to be active during treatment. However, there is very little information, and in particular a lack of guidelines, on exercising available to patients. The interventional trials that have been conducted on this topic are very heterogeneous and no standard recommendations have been made available for cancer patients thus far. An effective physical activity program needs to take each patient's barriers and motivations into account in order to encourage the practice of physical activity throughout treatment. To ensure the success of the program, it is essential to facilitate adherence and especially maintain motivation. Further studies are needed to determine what practice guidelines oncologists should give their patients.

RESUMEN

BACKGROUND: Young patients with breast cancer treated with chemotherapy can experience ovarian failure, which can lead to chemotherapy-induced menopause (CIM) impacting the quality of life (QoL). A prospective study was set out to evaluate the impact of CIM on QoL in women of childbearing age with non-metastatic breast cancer, and this article reports results of the interim analysis conducted to evaluate feasibility and to see preliminary results. PATIENTS AND METHODS: A total of 58 women (age, 18-46 years) with newly diagnosed breast cancer and treated with chemotherapy were eligible. QoL was assessed by self-administered questionnaires (Quality of Life Questionnaire-Core 30 [QLQ-C30], Quality of Life Questionnaire-Breast 23 [QLQ-BR23], and Kupperman index) and hormonal variations (anti-Müllerian hormone [AMH], follicle-stimulating hormone, and estradiol) were explored. We compared patients with ≥ 12 months amenorrhea (CIM) (n = 41) to patients with < 12 months of amenorrhea (non-CIM) (n = 17). RESULTS: A good inclusion rate (approximately 4/month) and sufficient data enabled us to perform this analysis. QLQ-C30 failed to show any difference between CIM and non-CIM patients (P = .5). In contrast, at 6 months post-chemotherapy, CIM patients tended to have lower QoL as shown by QLQ-BR23 (P = .16) and more severe climacteric symptoms (P = .01). Regarding hormonal variations, AMH pre-treatment level was higher in non-CIM patients (P = .0032). We also noted that CIM patients were older (P = .00013), had shorter menstruation cycle (P = .082), and experienced faster amenorrhea (P = .088). CONCLUSIONS: The study is technically feasible, and our preliminary results underline that age in association with pre-treatment AMH level could be helpful to predict ovarian function. QLQ-BR23 seemed to be stronger, more precise, and appropriate to evaluate QoL changes in patients with breast cancer than the QLQ-C30.

RESUMEN

BACKGROUND: Weight changes during adjuvant treatment for early-stage breast cancer has been associated with a poor prognosis. The long-term evolution of body composition during adjuvant treatment for breast cancer, in particular, endocrine therapy, is not well known, and new data on this topic are required. The present study assessed the evolution of weight and body composition among 33 postmenopausal breast cancer patients receiving endocrine therapy after standard adjuvant chemotherapy that included taxanes. PATIENTS AND METHODS: Dual-energy x-ray absorptiometry was used to measure the fat and lean body mass. Body water was assessed using multifrequency bioelectrical impedance analysis. The Hospital Anxiety and Depression questionnaire and the short version of the International Physical Activity Questionnaire were also administered. RESULTS: During endocrine therapy, 5 of the 33 patients (15.2%) lost weight and 12 (36.4%) gained weight. The overall average gain was 2.0 ± 5.5 kg (P = .04). During this period, the fat mass, lean body mass, and body water increased. The factors linked to fat mass gain included an excess fat mass (≥ 36%) before treatment and weight loss during chemotherapy. In the overall period of adjuvant cancer treatment, 30% of the population gained > 5% of their initial weight. The average gain was the same as that during the endocrine therapy period (2.0 ± 5.4 kg; P = .031) and was characterized by an increase in total lean body mass, mainly localized in the trunk region. CONCLUSION: Endocrine therapy appears as a pivotal period in weight and body composition management. Overfat and obese patients and those who lose weight during chemotherapy were more subject to weight and fat mass gain during endocrine therapy.
