[Retrospective study: Late surgery post chemotherapy versus after 3-4 cures in treatment of advanced ovarian cancer]. / Étude rétrospective : chirurgie d'intervalle tardive post chimiothérapie versus après 3­4 cures dans le cadre de la prise en charge d'un cancer de l'ovaire localement avancé non opérable d'emblée.

INTRODUCTION: Treatment in locally advanced ovarian cancer is optimal surgery followed by chemotherapy. Patients with significant tumor spread, OMS>2, age>75 years old are poor candidates for aggressive primary surgery. Interval surgery, after neo-adjuvant chemotherapy, aims to achieve more complete surgery, increase survival, and reduce surgical morbidity. The primary endpoint was progression-free survival. Secondary outcomes were overall survival and postoperative morbidity and mortality. METHOD: This is a retrospective study conducted in 2 French referral centers between January 2000 and December 2015. Patients who could not benefit from a complete initial surgery were operated after 3 cures of chemotherapy at the François Baclesse center and after least 5 cures at the center René Gauducheau. RESULTS: The population analyzed included 104 patients, 43 (41.0%) patients treated at the René Gauducheau center (group 1) and 61 (59.0%) patients treated at the François Baclesse center (group 2). Progression-free and overall survival were similar between the 2 groups, they were, respectively, 15.9 months and 34 months in group 1 vs. 15.4 months and 37.6 months in group 2 (P=0.72; P=0.65). Mean hospital stay and postoperative morbidity were similar in both groups. CONCLUSION: For weak patients, to limit invasive surgery, doing more than 5 courses of chemotherapy may be a reasonable option.

Comparative study of hypoglycaemia induced by opioids. Is it a class effect?

Objective: Drug-induced hypoglycaemia has been described with the use of tramadol and methadone. The authors aimed to determine if drug-induced hypoglycaemia could be a class effect for opioids. Methods: The authors performed a disproportionality analysis in VigiBase®, the WHO global individual case safety report database with nine opioids (codeine, fentanyl, hydromorphone, methadone, morphine, oxycodone, tramadol, buprenorphine and nalbuphine) using the broad Standardised MedDRA Query for hypoglycaemia. The authors also carried out a descriptive study of opioid-induced hypoglycaemia in the French PharmacoVigilance DataBase (FPVDB) using the MedDRA Preferred Term 'hypoglycaemia'. Results: The global adjusted Reporting Odds Ratio (aROR) value for the 9 opioids was 1.53 (95% CI 1.52-1.54). The aROR ranged from 1.09 to 1.97 depending on the opioid, but all were statistically significant. A sex ratio of 0.74 was found for the reports of opioid-induced hypoglycaemia in Vigibase®. The authors also found 133 reports of hypoglycaemia in the FPVDB related to opioids. Among the reports, 55 were glycaemic imbalances in diabetics occurring shortly after the start of opioid treatment. Conclusion: This work highlighted a significant association between all opioids and hypoglycaemia, thereby indicating that opioid-induced hypoglycaemia is probably a class effect. Women and/or diabetics seem to be more at risk for developing opioid-induced hypoglycaemia.

Nivolumab Causing a Polymyalgia Rheumatica in a Patient With a Squamous Non-Small Cell Lung Cancer.

The anti-programmed cell-death-1 antibody, nivolumab, has been recently approved for the treatment of advanced non-small cell lung cancer. Although, today, immune-related adverse effects such as dermatologic, digestive, hepatic, and endocrine toxicities are well-known with immune checkpoint inhibitors, rheumatic diseases are less well described. Herein, we report the case of a patient without a history of arthritis who developed polymyalgia rheumatica after 13 cycles of nivolumab used for the treatment of advanced non-small cell lung cancer. Laboratory evidence of inflammatory syndrome, articular echography, and clinical presentation with classical symptoms and also distal manifestations were suggestive of this chronic inflammatory disorder. Because of a relevant pain, clinicians were forced to suspend immunotherapy. Nevertheless, due to glucocorticoid therapy, the patient's symptoms have decreased progressively. Moreover, nivolumab was reintroduced 8 weeks later, whereas prednisone (10 mg) was continued, without any recurrence symptoms. To conclude, our case suggests that polymyalgia rheumatica might be a very disabling anti-programmed cell-death-1 immune-related adverse effect.
