Validation of reference genes in human chordoma.
CONCLUSION: In gene expression studies of human chordomas, PGK1, ACTB, and YWHAZ are more stably expressed, and therefore, are preferred reference genes over the most often used reference gene so far, GAPDH. PMID: 28695047 [PubMed - in process]
SUMMARY: Chordomas are rare primary bone malignancies derived from notochord remnants. The tumors often are slow-growing and often present with indolent, nonspecific symptoms. Nevertheless, chordomas are locally aggressive and highly prone to local recurrence, necessitating precise planning before biopsy and/or surgical resection. Familiarity with the imaging features of chordomas is, therefore, essential. This case highlights the typical imaging and pathologic features of a spinal chordoma as well as the surgical approach and the patient’s subsequent outcome.
We present a case of acute myeloid leukemia developing during treatment of localized chordoma of the clivus in a 20-month-old male. We propose a genomic relationship that may have contributed to the development of clival chordoma and acute myeloid leukemia without a latency period and advocate for genomic sequencing in children with chordoma before the initiation of systemic therapies.
CONCLUSION: Our retrospective nationwide multicentre study showed that CIRT for sacral chordoma was effective and safe, and replicated the previously reported data from a representative CIRT institution in Japan demonstrating high local control and low toxicity rates.

Chordoma is a slow-growing but locally aggressive tumour arising from remnants of the notochord. According to recent reports based on the surveillance, epidemiology, and end results (SEER) database in the United States, chordomas in the sacrococcygeal region comprise approximately 30% of all chordomas,[2,3] and the age-adjusted incidence rate is 0.03 per 100,000. The primary definitive treatment for sacral chordoma is surgical resection; however, complete resection is often difficult due to the complex anatomy.
ConclusionThis survey has demonstrated that, although there is reasonable confidence in the role of PBT among ANZ radiation oncologists, there are a number of important aspects of PBT awareness, education and access that need to be developed prior to commencement of PBT in Australia.
Conclusion. Even more than during normal times, a multidisciplinary approach is mandatory to share the decision to modify a treatment strategy. Level of Evidence: 5
CONCLUSIONS: Through multicentric data collection, this study encompasses the largest series in the literature of clival chordomas surgically treated through an EETA. An increase in the use of this approach was found among Italian neurosurgical departments together with an improved extent of resection over time. The satisfactory rate of GTR was marked by low surgical morbidity and the preservation of patient quality of life. Surgical outcome was reinforced, in terms of PFS and OS, by the use of proton beam therapy, which was increasingly performed along the period of study.

We describe the use of a clamshell thoracotomy for en bloc excision of a 3-level upper thoracic chordoma in a 20-year-old patient. The lesion involved T2, T3, and T4, and it invaded both chest cavities and indented the mediastinum. After 2 biopsies to confirm the diagnosis, the patient underwent a posterior spinal fusion followed by bilateral clamshell thoracotomy for 3-level en bloc resection with simultaneous access to both chest cavities and the mediastinum. To demonstrate how the clamshell thoracotomy was used to facilitate the tumor resection, an operative video and illustrations are provided, which show in detail how...
Conclusion: The results of this study indicate that hip arthroplasty is a durable treatment option for patients with metastatic disease or coxarthrosis following subtotal sacrectomy for chordoma.
