ABSTRACT
Epithelial ovarian cancer (EOC) is usually diagnosed at an advanced stage and significantly contributes to cancer mortality in women. Despite multimodal treatment associating chemotherapy and surgery, most patients ultimately progress and require palliative systemic therapy. In EOC, the efficacy of anti-HER2 agents is minimal even after selecting patients for HER2 expression. ERBB2 gene amplification is observed in 3-10% of patients, depending on the specific method of detection and cutoffs. We report the case of a young woman with a FIGO stage IV high-grade serous ovarian cancer with an amplification of ERBB2. She was treated with the association of trastuzumab - pertuzumab after two lines of standard treatment and presented an excellent long-lasting partial response after 36 months of treatment. The association of trastuzumab and pertuzumab, without chemotherapy, has not been previously tested in this context and could be more efficacious than monotherapy with either agent. In addition, the significant benefit observed in this case could be attributed to the presence of a high-level focal amplification that is relatively rare and probably more specific than an increase in HER2 expression. In conclusion, prospective trials of the trastuzumab and pertuzumab combination should be considered in an appropriately selected EOC patient population.
ABSTRACT
Fasting is becoming an increasingly popular practice. Nevertheless, its clinical benefits and possible inconveniences remain limitedly evaluated. We observed the effects of a seven-day fast conducted in a non-medical center located in the Swiss Alps. Clinical parameters were measured on the first and last day of fasting (D1 and D7), and two months later (D60). Among the 40 participants, blood analyses were done on 25 persons with an increased metabolic risk, with the primary goal of assessing the lasting effect on low-density lipoprotein (LDL) cholesterol. By comparing D60 with D1, high-density lipoprotein cholesterol (HDL) (+0.15 mmol/L) and insulin-like growth factor-1 (IGF-1) (+2.05 mmol/L) increased (both p < 0.009), all other blood parameters (LDL, glucose, total cholesterol, triglycerides, C-reactive protein (CRP)) did not change; weight (-0.97 kg) and hearth rate (-7.31 min-1) decreased (both p < 0.006). By comparing D7 with D1, total cholesterol (+0.44 mmol/L), triglycerides (+0.37 mmol/L) and CRP (+3.37 mg/L) increased (all p < 0.02). The lack of LDL variation at D60 may be due to the low metabolic risk level of the participants. The increase of total cholesterol, triglycerides and CRP at D7 warrants studies to understand whether such fluctuations represent a stress reaction to the fasting state, which may vary in different fasting types.

Fasting concomitantly with oncology treatments (chemotherapy mainly) induces a growing interest among patients following overmediatisation of recent discoveries. The goal of this article is to provide updated information about this approach. According to preclinical studies, fasting may be a way to increase the therapeutic index of major oncology treatments. However, clinical data is based on small exploratory studies only and the results of larger scale studies are not yet available. The approach of fasting during chemotherapy can and should neither be recommended nor implemented in standard care. However, further scientific and clinical investigation may contribute to a better understanding of the metabolic aspects of cancer.
Jeûner au cours des traitements oncologiques (de la chimiothérapie en particulier) génère un intérêt croissant auprès des patients suite à la surmédiatisation de récentes découvertes. Le but de cet article est de faire un état des lieux sur les bases scientifiques de cette approche. Selon des études précliniques, le jeûne pourrait augmenter l'index thérapeutique des principaux traitements oncologiques. Mais les données cliniques manquent cruellement, malgré quelques données émanant de petites études exploratoires. Les études à plus grande échelle sont en cours. Aujourd'hui, l'approche du jeûne pendant la chimiothérapie ne peut et ne doit être ni recommandée ni introduite dans des protocoles de soins. Son étude peut par contre améliorer la compréhension des aspects métaboliques du cancer.
ABSTRACT
The ever-increasing use of immune checkpoint inhibitors in cancer is leading to a high incidence of autoimmune side effects. This report discusses an autoimmune fulminant myocarditis in an elderly patient with metastatic pulmonary adenocarcinoma in whom the most advanced invasive heart failure therapies were used successfully. She was treated with nivolumab. This case illustrates a severe cardiovascular complication of immunotherapy and highlights to cardiologists the importance of aggressive treatments in patients with metastatic cancers whose prognosis has improved dramatically.
