Background: The International Germ Cell Consensus Classification(IGCCC) is the internationally accepted, clinically based prognosticclassification used to assist in the management and research ofmetastatic germ cell tumours (GCTs). The goal of this study wasto determine whether the IGCCC is applicable to a populationbasedcohort.Methods: We completed a retrospective chart review of patientswho received diagnoses of GCT in Nova Scotia between 1984and 2004 and who received treatment with platin-based chemotherapyfor metastatic disease. We assigned the IGCCC to eachpatient based on the site of the primary lesion, the presence orabsence of nonpulmonary visceral metastases and prechemotherapytumour marker values. We calculated Kaplan–Meier estimatesof 5-year progression-free survival (PFS) and overall survival foreach IGCCC group.Results: The study cohort comprised 129 patients. The distributionand outcomes in each group of patients in Nova Scotia was similarto that published in the IGCCC. Among patients with nonseminomaGCTs (NSGCT) 61% had good, 22% had intermediate and17% had poor prognoses. Among those with seminomas, 85% hadgood and 15% had intermediate prognoses. Among patientswith NSGCTs, the 5-year PFS was 90%, 69% and 55%, and the5-year overall survival was 94%, 84%, 61% in the good, intermediate,and poor prognostic categories respectively. Amongpatients with seminomas, the 5-year PFS was 95% and 50% andthe 5-year overall survival was 94% and 50% in the good and intermediateprognostic categories, respectively.Conclusion: The IGCCC seems applicable to a population-basedcohort, with similar distribution of categories and clear prognosticability.Contexte : L’IGCCC (International Germ Cell Consensus Classification)est un système de classification pronostique mondialementreconnu, basé sur les données cliniques et utilisé pour faciliterla prise en charge des tumeurs germinales métastatiques et larecherche sur ces tumeurs. Le but de la présente étude était de déterminersi cette classification s’applique à une cohorte de population.Méthodologie : On a mené une étude rétrospective par examen dedossiers de patients ayant reçu un diagnostic de tumeur germinaleen Nouvelle-Écosse entre 1984 et 2004 et traités par chimiothérapieantimétastatique à base de platine. On a classé les patients selonl’IGCCC en fonction du siège de la tumeur primitive, de la présenceou de l’absence de métastases viscérales non pulmonaires et desvaleurs des marqueurs tumoraux avant la chimiothérapie. La surviesans progression de la maladie (SSP) et la survie globale (SG)sur 5 ans pour chaque groupe formé en fonction de l’IGCCC ontété évaluées par la méthode de Kaplan-Meier.Résultats : La cohorte étudiée comptait 129 patients. La distributionet l’issue du traitement étaient similaires pour tous lespatients à celles publiées dans la classification IGCCC. Chez lespatients avec tumeurs germinales non séminomateuses, 61 %avaient un pronostic favorable, 22 % un pronostic moyen et 17 %un pronostic médiocre. Chez les patients avec tumeurs séminomateuses,85 % avaient un pronostic favorable et 15 % un pronosticmoyen. Chez les patients avec tumeurs germinales non séminomateuses,la SSP après 5 ans était de 90 %, 69 % et 55 % etla survie globale après 5 ans était de 94 %, 84 % et 61 % en fonctionde pronostiques favorable, moyen et médiocre, respectivement.Chez les patients avec tumeurs séminomateuses, la SSP après 5 ansétait de 95 % et 50% et la survie globale après 5 ans était de94 % et 50 % en fonction de ces mêmes catégories pronostiques.Conclusion : L’IGCCC semble bien s’appliquer à une cohorte depopulation; la distribution entre les classes est similaire, et la capacitépronostique est très bonne.

14625 Background: The IGCCC is the internationally accepted, clinically based, prognostic classification used to aid in the management of GCT. The goal of this study was to determine if the IGCCC is applicable to a population based cohort. Methods: A retrospective chart review of all patients diagnosed with GCT in NS between 1984–2004 was completed, and IGCCC classification (good, intermediate, poor) was assigned to each patient based on the site of the primary lesion, the presence or absence of non-pulmonary visceral metastases and pre-chemotherapy tumor marker values. Kaplan-Meier estimates of five year progression free survival (PFS) and overall survival (OS) were calculated for each IGCCC group, for both non-seminomatous GCT and seminomatous GCT. Results: The distribution, PFS and OS are shown below. Conclusions: The IGCCC seems applicable to a population-based cohort, with similar distribution of categories, as well as clear prognostic ability.

ObjectivePatients with central nervous system germ cell tumours (CNS-GCTs) commonly initially present to primary care or general paediatricians. Prolonged symptom intervals (SI) are frequently seen in CNS-GCTs and have been associated with inferior outcomes in other brain tumours. This study reviewed the clinical presentation of CNS-GCTs and examined the effect of prolonged SI.Design/Setting/Patients/OutcomesInternational multicentre 10-year retrospective study (2002–2011 inclusive), across six international paediatric oncology treatment centres. All newly diagnosed patients with CNS-GCT were included. Main outcome measure was time interval from first symptom to diagnosis.ResultsThe study cohort included 86 (58 males:28 female) patients (59 ‘germinoma’ and 27 ‘non-germinomatous’ GCTs), with tumours being pineal (n=33), suprasellar (n=25), bifocal (pineal+suprasellar; n=24) and ‘other’ site (n=4), of which 16 (19%) were metastatic. Median age at diagnosis was 14 years (0–23 years). The time to diagnosis from first symptom (SI) was 0–69 months (median 3 months, mean 9 months). A prolonged SI (>6 months) was observed in 28/86 patients (33%) and significantly associated with metastatic disease (11/28 (39%) vs 5/58 (9%); p=0.002)) at diagnosis, but not overall survival. With prolonged SI, endocrine symptoms, particularly diabetes insipidus, were more common (21/28 (75%) vs 14/58 (24%) patients; p<0.002), but raised intracranial pressure (RICP) was less frequent (4/28 (14%) vs 43/58 (74%) patients; p<0.001)) at first symptom.ConclusionsOne-third of patients with CNS-GCT have >6 months of symptoms prior to diagnosis. Delayed diagnosis is associated with metastatic disease. Early symptom recognition, particularly related to visual and hormonal disturbances in the absence of RICP, may improve timely diagnosis, reduce metastatic disease frequency and consequently reduce treatment burden and late effects.

Objectives: Malignant ovarian germ cell tumours (MOGCTs) are rare, but aggressive tumours seen mostly in young women or adolescent girls. The aim of our study was to evaluate the survival outcomes of MOGCT patients treated at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan. Materials and Methods: One hundred and nine females were retrospectively identi ed through hospital information system with MOGCT from 2007 to 2013. Histology was based on the WHO classi cation. Tumours were staged according to the Federation of Gynaecology and Obstetrics staging system. Overall survival (OS) and disease-free survival (DFS) were determined by the Kaplan–Meier method. All patients were included in the study. Patient who had been lost to follow-up was contacted through telephone. Results: Mean presenting age was 20 years (range 4–54). 38% of patients had Stage I, 7% had Stage II, 25% had Stage III and 30% of patients had Stage IV disease. Based on histology, 42% had dysgerminoma, 25% had mixed germ cell tumours, 18% had yolk sac tumour, 13% had teratoma and 2% had embryonal carcinoma. Median follow-up time was 41 months. All patients underwent initial surgery, of which 86 (79%) had fertility-preserving surgery. 91 (84%) patients received adjuvant chemotherapy and 18 (16%) were kept on surveillance. The chemotherapy regimen used was a combination of bleomycin, etoposide and cisplatin. 89 patients had a complete remission, 14 had partial response and one had progressive disease. Five patients had relapsed disease, four distant and one local. The 5 year OS was 91% and DFS was 88%. Conclusion: MOGCTs have a good prognosis. Fertility-sparing surgery was possible in the majority of cases. BEP regimen has excellent activity and acceptable toxicity in patients with MOGCT. Key words: Disease-free survival, malignant ovarian germ cell tumours, overall survival

Testicular cancer is the most common cancer in men aged from 15 to 34 years. Lymphovascular invasion refers to the presence of tumours within endothelial-lined lymphatic or vascular channels, and has been shown to have prognostic significance in testicular germ cell tumours. In non-seminomatous tumours, lymphovascular invasion is the most powerful prognostic factor for stage 1 disease. For the pathologist, searching multiple slides for lymphovascular invasion can be highly time-consuming. The aim of this retrospective study was to develop and assess an artificial intelligence algorithm that can identify areas suspicious for lymphovascular invasion in histological digital whole slide images. Areas of possible lymphovascular invasion were annotated in a total of 184 whole slide images of haematoxylin and eosin (H&E) stained tissue from 19 patients with testicular germ cell tumours, including a mixture of seminoma and non-seminomatous cases. Following consensus review by specialist uropathologists, we trained a deep learning classifier for automatic segmentation of areas suspicious for lymphovascular invasion. The classifier identified 34 areas within a validation set of 118 whole slide images from 10 patients, each of which was reviewed by three expert pathologists to form a majority consensus. The precision was 0.68 for areas which were considered to be appropriate to flag, and 0.56 for areas considered to be definite lymphovascular invasion. An artificial intelligence tool which highlights areas of possible lymphovascular invasion to reporting pathologists, who then make a final judgement on its presence or absence, has been demonstrated as feasible in this proof-of-concept study. Further development is required before clinical deployment.
