Is carboplatin-based chemotherapy as effective as cisplatin-based chemotherapy in the treatment of advanced-stage dysgerminoma in children, adolescents and young adults?

Objective: Dysgerminoma is the most common malignant ovarian germ cell tumor (GCT) with peak incidence during adolescence and young adulthood. Current standard of care for patients with disease that has spread outside of the ovary (advanced-stage) utilizes platin-based chemotherapy regimens. The study objective was to compare clinical outcomes between platin-based (carboplatin versus cisplatin) strategies across all age groups (children < 11 years (y), adolescents = 11-25 y and young adult women > 25 y) for advanced-stage dysgerminoma.

Comparison of carboplatin versus cisplatin in the treatment of paediatric extracranial malignant germ cell tumours: A report of the Malignant Germ Cell International Consortium.

Purpose: To compare the outcomes of paediatric and adolescent extracranial malignant germ cell tumour (GCT) patients treated with either carboplatin or cisplatin on clinical trials conducted by the Children's Oncology Group (COG) and the Children's Cancer and Leukaemia Group (CCLG).

Methods: The Malignant Germ Cell International Consortium (MaGIC) has created a database of the GCT clinical trials conducted since 1983 by COG (United States, Canada and Australia), which used cisplatin-based regimens, and by CCLG (United Kingdom), which used carboplatin-based regimens. Using the parametric cure model, this study compared the overall 4-year event-free survival (EFS), stratified by age, stage, site and the a-priori defined MaGIC 'risk' groups: standard risk ((SR) 1 (EFS >80%; age <11 years), SR2 (EFS >80%, age ≥ 11y) and poor risk (PR) (EFS ≤ 70%, age ≥ 11y).

Treatment and outcomes of UK and German patients with relapsed intracranial germ cell tumors following uniform first-line therapy.

We aimed to retrospectively assess treatments/outcomes, including the value of high-dose-chemotherapy and autologous-stem-cell-rescue (HDC + AuSCR) and re-irradiation, in a large, European patient-cohort with relapsed intracranial germ-cell-tumors (GCTs) receiving uniform first-line therapy, including radiotherapy as standard-of-care. Fifty-eight UK/German patients (48 male/10 female) with relapsed intracranial-GCTs [13 germinoma/45 non-germinomatous GCT (NGGCT)] treated 1996-2010 as per the SIOP-CNS-GCT-96 protocol were evaluated. For germinoma, six patients relapsed with germinoma and five with NGGCT (one palliative, one teratoma patient excluded).

Fertility Preservation Care for Children and Adolescents with Cancer: An Inquiry to Quantify Professionals' Barriers.

Purpose: There is a growing interest in fertility preservation as emerging research is highlighting the prevalence of infertility among young cancer survivors and its negative impact on quality of life. Previous qualitative research has identified barriers of fertility preservation care among professionals. The aim of this study was to assess the prevalence of these barriers among pediatric and adolescent oncology healthcare professionals and evaluate factors that influence them.

Comparison of MAPIE versus MAP in patients with a poor response to preoperative chemotherapy for newly diagnosed high-grade osteosarcoma (EURAMOS-1): an open-label, international, randomised controlled trial.

Background: We designed the EURAMOS-1 trial to investigate whether intensified postoperative chemotherapy for patients whose tumour showed a poor response to preoperative chemotherapy (≥10% viable tumour) improved event-free survival in patients with high-grade osteosarcoma.

Methods: EURAMOS-1 was an open-label, international, phase 3 randomised, controlled trial. Consenting patients with newly diagnosed, resectable, high-grade osteosarcoma aged 40 years or younger were eligible for randomisation.

Paediatric extracranial germ-cell tumours.

Management of paediatric extracranial germ-cell tumours carries a unique set of challenges. Germ-cell tumours are a heterogeneous group of neoplasms that present across a wide age range and vary in site, histology, and clinical behaviour. Patients with germ-cell tumours are managed by a diverse array of specialists.

Is adjuvant chemotherapy indicated in ovarian immature teratomas? A combined data analysis from the Malignant Germ Cell Tumor International Collaborative.

Background: There is a debate regarding the management of ovarian immature teratomas (ITs). In adult women, postoperative chemotherapy is standard except for stage I, grade 1 disease, whereas surgery alone is standard in pediatric patients. To determine the role of chemotherapy, a pooled analysis of pediatric and adult clinical trials was conducted.

Pediatric and Adolescent Extracranial Germ Cell Tumors: The Road to Collaboration.

During the past 35 years, survival rates for children with extracranial malignant germ cell tumors (GCTs) have increased significantly. Success has been achieved primarily through the application of platinum-based chemotherapy regimens; however, clinical challenges in GCTs remain. Excellent outcomes are not distributed uniformly across the heterogeneous distribution of age, histologic features, and primary tumor site.

Socioeconomic patterning in the incidence and survival of teenage and young adult men aged between 15 and 24 years diagnosed with non-seminoma testicular cancer in northern england.

Purpose: Previous research from developed countries has shown a marked increase in the incidence of testicular cancer in the past 50 years. This has also been demonstrated in northern England, along with improving 5-year survival. The present study aims to determine if socioeconomic factors may play a role in both etiology and survival from non-seminoma testicular cancer.

Revised risk classification for pediatric extracranial germ cell tumors based on 25 years of clinical trial data from the United Kingdom and United States.

Purpose: To risk stratify malignant extracranial pediatric germ cell tumors (GCTs).

Patients And Methods: Data from seven GCT trials conducted by the Children's Oncology Group (United States) or the Children's Cancer and Leukemia Group (United Kingdom) between 1985 and 2009 were merged to create a data set of patients with stage II to IV disease treated with platinum-based therapy. A parametric cure model was used to evaluate the prognostic importance of age, tumor site, stage, histology, tumor markers, and treatment regimen and estimate the percentage of patients who achieved long-term disease-free (LTDF) survival in each subgroup of the final model.

Adolescents and young adults with a "rare" cancer: getting past semantics to optimal care for patients with germ cell tumors.

Because the tumors of adolescence and young adulthood (AYA) are distinct from those that occur earlier and later in life, the most common tumors in this age group are termed “rare.” We offer a collaborative, cross-disciplinary, evidence-based approach, advocated and funded by civil society, to advance the field of germ cell tumor and potentially to apply to other rare AYA tumors.

An international strategy to determine the role of high dose therapy in recurrent Wilms' tumour.

Purpose: To review event-free (EFS) and overall survival (OS) from publications describing outcome for children with relapsed Wilms' tumour. Comparisons are made between those receiving myeloablative high dose chemotherapy with autologous stem-cell rescue (HDT) and those not (NoHDT).

Materials And Methods: Relevant information was extracted from individual patient or summary data and 3-year EFS and OS rates established.

Intra-abdominal metastasis of an intracranial germinoma via ventriculo-peritoneal shunt in a 13-year-old female.

A 13-year-old patient presented with massive intra-abdominal metastasis and spontaneous acute tumour lysis syndrome, 17-months after VP shunt placement for metastatic pineal germinoma treated with cranio-spinal-irradiation. Hyperhydration/rasburicase improved renal function, allowing chemotherapy with subsequent surgery. The patient remains event-free 34-months later.

Young males' experiences of sperm banking following a cancer diagnosis - a qualitative study.

Existing research into sperm banking by young males following a cancer diagnosis is predominantly quantitative; little is known about personal experiences, psychosocial and attitudinal barriers to it amongst patients and/or professionals, or the later impact of potential or actual subfertility when banking has or has not taken place. This qualitative study used single in-depth interviews with 16 males aged 13 to 20 at diagnosis (16 to 30 years at interview) to report retrospectively on their experiences, concerns and satisfactions. There was support for sperm banking, including among those who declined to bank or failed to do so successfully.

Mature and immature extracranial teratomas in children: the UK Children's Cancer Study Group Experience.

Purpose: The purpose of this article is to describe the features, treatment, and risk factors for relapse of children with mature teratoma (MT) and immature teratoma (IT) to assist future treatment plans.

Patients And Methods: Patients were younger than 16 years of age and referred to the UK Children's Cancer Study Group centers with biopsy-proven extracranial MT and IT and no prior chemotherapy. Complete excision, with the coccyx in sacrococcygeal patients, and follow-up, including serum alpha-fetoprotein monitoring for early detection of malignant yolk sac tumor (YST) recurrence, were recommended.
