1 Cancer and Deafness Associated With the Use of Platinum Derivatives in Children

A limited number of relatively contradictory studies have suggested that the development of serious ototoxicity in children treated with cisplatin or, more rarely, carboplatin could be partly related to genetic risk factors affecting detoxification enzymes and membrane transporters of platinum derivatives. The objective of this study is therefore to identify genetic variants associated with the development of platinum ototoxicity in patients treated with cisplatin or carboplatin (minimum follow-up of 3 years) for one of the following diseases: neuroblastoma, hepatoblastoma, retinoblastoma, malignant germ cell tumour, osteosarcoma, high-risk or recurrent Wilms' tumour, non-parameningealrhabdomyosarcoma. A total of 180 patients, corresponding to 60 cases with grade 3 or 4 ototoxicity and 120 controls with no signs of ototoxicity (separate complete audiograms for each ear) will be included. A saliva sample will be used to obtain DNA for pharmacogenetic studies. The value of this study will be to define a population at high risk of developing ototoxicity in order to adapt treatment, or even develop preventive treatment of ototoxicity based on antioxidant medications

NCT02425397 Cancer in Children. Hearing Loss Genetic: Genetic study Genetic: Genetic study MT-RN1

MeSH:Hearing Loss Deafness

HPO:Hearing impairment

An A/G polymorphism situated in the substrate binding domain of the GSTP1 isoenzyme in position +313 of exon 5 (A313G) induces substitution of a isoleucine by a valine (Ile105Val). --- A313G --- --- Ile105Val ---

Finally, the role of GSTP1 Ile105Val polymorphism has not been evaluated in children (Barahmani et al., 2009). --- Ile105Val ---

Primary Outcomes

Measure: genetic factors (drug metabolism enzymes, membrane transporters) predisposing to cisplatin and carboplatin ototoxicity in children

Time: Day 0

Secondary Outcomes

Measure: genetic factors predisposing to aminoglycoside ototoxicity;

Time: Day 0

Measure: To provide a rationale for prevention of ototoxicity by the use of antioxidant medications.

Time: Day 0

2 Phase II(Window) Preoperative Study of Olaparib With Cisplatin or With Durvalumab (MEDI4736) or Alone or no Treatment in Patients With Histologically Proven Squamous Cell Carcinoma of the Head and Neck Who Are Candidates for Surgery.

OPHELIA (OPHELIA (OlaParib and durvalumab in HEad and neck squamous celL carcInomA) trial is a Greek, investigator-initiated, randomized open-label window-of-opportunity phase II study. Patients with operable histologically documented squamous-cell carcinoma of the oral cavity, oropharynx, hypopharynx or larynx will be randomized between combination with durvalumab and olaparib, cisplatin and olaparib, monotherapy with olaparib or no treatment, before starting standard treatment.
