Very long-term outcomes of pediatric patients treated for optic pathway gliomas: A longitudinal cohort study.

BACKGROUND: Optic pathway gliomas (OPG) represent 5% of childhood brain tumors. Successive relapses lead to multiple treatments exposing to late complications. METHODS: We included patients treated at Gustave Roussy (GR) between 01.1980 and 12.2015 for OPG, before 18 years-old and alive at 5 years from diagnosis. Mortality and physical health conditions data were extracted from medical data files and updated thanks to the GR long-term follow-up program and French national mortality registry for patients included in the French Childhood Cancer Survivor Study. RESULTS: We included 182 5y-OPG-childhood survivors in the analysis (sex-ratio M/F 0.8, 35% with NF1). With a median follow-up of 17.2y (range=5-41), we registered 82 relapses, 9 second malignancies and 15 deaths as first events after 5 years, resulting in 20-y conditional overall survival (C-OS) and late events-free survival (LEFS) of 79.9% (95%CI=71-86) and 43.5% (95%CI=36-51) respectively. NF1 (Hazard ratio HR=3, 95%CI=1.4-6.8), hypothalamic involvement (HR=3.2, 95%CI=1.4-7.3), and radiotherapy (HR=2.8, 95%CI=1.1-6.7) were significantly associated with C-OS in multivariable analyses. Ninety-five percent of 5y-OPG survivors suffered from any health condition, especially visual acuity "<1/10" (n=109), pituitary deficiency (n=106) and neurocognitive impairment (n=89). NF1 (HR 2.1) was associated with precocious puberty. With a median time post diagnosis of 4.2 years, 33 cerebrovascular events were observed in 21 patients. CONCLUSION: Late relapses, second malignancies and cerebrovascular diseases are severe late events resulting in premature mortality. Morbidity is high and needing after-cancer care to improve quality of life. Risk factors could be considered to better stratify long-term follow-up.

Long-term follow-up of high-risk neuroblastoma survivors treated with high-dose chemotherapy and stem cell transplantation rescue.

Intensive treatments including high-dose chemotherapy (HDC) with autologous stem cell rescue have improved high-risk neuroblastoma (HRNB) survival. We report the long-term health status of 145 HRNB survivors, alive and disease-free 5 years post HDC. Median follow-up was 15 years (range = 5-34). Six patients experienced late relapses, 11 developed second malignant neoplasms (SMNs), and 9 died. Event-free and overall survivals 20 years post HDC were 82% (95% CI = 70%-90%) and 89% (78%-95%), respectively. Compared with the French general population, the standardized mortality ratio was 19 (95% CI = 8.7-36.1; p < 0.0001) and the absolute excess risk was 37.6 (19.2-73.5). Late effects were observed in 135/145 patients (median = 3 events/patient); 103 had at least one severe event. SMNs arose at a median of 20 years post HDC and included carcinoma (n = 5), sarcoma (2), acute myeloid leukemia (2), melanoma (1), and malignant glioma (1). Non-oncologic health events included dental maldevelopment (60%), severe hearing loss (20% cumulative probability at 15 years), hepatic focal nodular hyperplasia (14%), thyroid (11%), cardiac (8%), and renal (7%) diseases and growth retardation (height-for-age z-score ≤ -2 for 21%). Gonadal insufficiency was near-universal after busulfan (40/43 females, 33/35 males). Severe late effects are frequent and progressive in HRNB survivors needing systematic very long-term follow-up.

Screening for psychological distress in very long-term adult survivors of childhood cancer.

This study evaluated the prevalence of psychological distress (PD) in a cohort of 348 adult childhood cancer survivors with a very long-term follow-up and assessed the characteristics associated with this distress (cancer type, treatment, sex, age at diagnosis, self-reported late effects, social support, type of remembrance, time since the diagnosis, age at evaluation), assuming that with time since the diagnosis, the PD of survivors will approximate that of the general population. Before attending a long-term follow-up consultation, survivors were sent 3 questionnaires: the Brief Symptom Inventory-18, the Impact of Event Scale, and the Illness Worry Scale (IWS). During the visit, they were administered the Mini-International Neuropsychiatric Interview (MINI) by a psychologist. The mean age of the survivors was 38.5 years (18.1-65.8) at consultation, 7 years (0.0-18.0) at cancer diagnosis, and mean time since diagnosis was 31.5 years (8.8-56.1). Multiple regression analyses of the data collected from self-administered questionnaires confirmed that being female, living alone, and self-reported late effects were associated with the high scores for all scales. Negative remembrances and being accompanied to the clinic were associated with higher IWS scores. Unlike the initial hypothesis, the MINI showed that, compared with controls, survivors experienced a higher prevalence of anxiety and mood disorders even after a very long time since the diagnosis. These findings show that a substantial subset of survivors experiment a high prevalence of PD, higher than the general population, and should be screened for PD whatever the time since the diagnosis.

[The psychological counseling in the long-term follow-up in oncology: Review and prospects]. / La consultation psychologique de suivi à long terme en oncologie : état des lieux et perspectives.

The aim of the article is to describe psychological counseling implemented in the context of the study of the long-term follow-up in oncology (SALTO in Rhône-Alpes-Auvergne and in Gustave-Roussy). The authors address the specificity of this consultation, proposed to adults who had childhood cancer, focusing in particular on the observed psychic movements. To conclude, the authors justify the interest of a clinical approach and the necessity of such psychological consultation for these former patients became adults.
