The standard treatment for gestational choriocarcinoma is chemotherapy. To describe the risk of recurrence with expectant management of gestational choriocarcinoma that has reached a normal human chorionic gonadotropin level after tumor removal without adjuvant chemotherapy. A retrospective multicenter international cohort study was conducted from 1981 to 2017 involving 11 gestational trophoblastic disease reference centers with patient's follow-up extended until 2023. Clinical and biological data of included patients were extracted from each center's database. The inclusion criteria were i) histological diagnosis of gestational choriocarcinoma in any kind of placental tissue retrieved, ii) spontaneous normalization of human chorionic gonadotropin level following choriocarcinoma retrieval, iii) patient did not receive any oncological treatment for the choriocarcinoma, iv) and at least 6 months of follow-up after the first human chorionic gonadotropin level normalization. Among 80 patients with retrieved gestational choriocarcinoma and whose human chorionic gonadotropin level normalized without any other oncological therapy, none had a recurrence of choriocarcinoma after a median follow-up of 50 months. The median interval between choriocarcinoma excision and human chorionic gonadotropin level normalization was 48 days. The International Federation of Gynecology and Obstetrics/World Health Organization risk score was ≤6 in 93.7% of the cases. This multicenter international study reports that selected patients with gestational choriocarcinoma managed in gestational trophoblastic disease reference centers did not experience any relapse when the initial tumor evacuation is followed by human chorionic gonadotropin level normalization without any additional treatment. Expectant management may be a safe approach for highly selected patients. • Gestational choriocarcinoma may be diagnosed after complete tumor excision while human chorionic gonadotropin level has already normalized. • This international study including 80 patients with normalized human chorionic gonadotropin after complete choriocarcinoma surgical evacuation supports that surveillance without chemotherapy is safe in the context of a highly selected patient population. • No recurrences were observed during the median follow-up of 4 years.

Abstract: Cerebrospinal fluid (CSF) total Tau levels vary widely in neurodegenerative disorders, thus being not useful in their discrimination over Alzheimer disease. No CSF marker for progressive supranuclear palsy (PSP) is currently available. The aim of this study was to characterise and measure Tau forms in order to verify the differential patterns among neurodegenerative disorders. Seventy-eight patients with neurodegenerative disorders and 26 controls were included in the study. Each patient underwent a standardised clinical and neuropsychological evaluation, MRI, and CSF total-Tau and phospho-Tau dosage. In CSF and cerebral cortex, a quantitative immunoprecipitation was developed. An extended (55kDa), and a truncated (33kDa) forms of Tau were recognised. CSF samples were assayed, the optical density of the two Tau forms was measured, and the ratio calculated (Tau ratio, 33kDa/55kDa forms). Tau ratio 33kDa/55kDa was significantly decreased in patients with PSP (0.46±0.16) when compared to controls, including healthy subjects (1.16±0.46, P =0.002) and Alzheimer disease (1.38±0.68, P <0.001), and when compared to frontotemporal dementia (0.98±0.30, P =0.008) or corticobasal degeneration syndrome (0.98±0.48, P =0.02). Moreover, in PSP patients Tau form ratio was lower than in other neurodegenerative extrapyramidal disorders, such as Parkinson disease (1.16±0.26, P =0.002) and dementia with lewy bodies (1.44±0.48, P <0.001). Tau ratio 33kDa/55kDa did not correlate either with demographic characteristics, cognitive performances or with motor impairment severity. Truncated Tau production shows a different pattern in PSP compared to other neurodegenerative disorders, supporting the view of disease-specific pathological pathways. These findings are promising in suggesting the identification of a marker for PSP diagnosis in clinical practice. [Copyright &y& Elsevier]
