Complete segmental resection of the spine, including the spinal cord, for telangiectatic osteosarcoma: a report of 2 cases.
Hideki Murakami,Katsuro Tomita,Norio Kawahara,Makoto Oda,Tetsutaro Yahata,Takehiko Yamaguchi +5 more
TL;DR: En bloc spinal resection, including the spinal cord, is an operation allowed when there is no hope for recovery of spinal cord function and should be accepted as an option in spine tumor surgeries.

Intentional marginal excision of osteosarcoma of the proximal fibula to preserve limb function.
Yoshimitsu Kanazawa,Hiroyuki Tsuchiya,Akitaka Nonomura,Koutarou Takazawa,Norio Yamamoto,Katsuro Tomita +5 more
TL;DR: Three cases of osteosarcoma (stage IIB) of the proximal fibula were successfully treated by marginal excision that preserved the common peroneal nerve and lateral stabilizers of the knee joint, providing a better quality of life than conventional wide excision.

Werner's syndrome combined with quintuplicate malignant tumors: a case report and review of literature data.
TL;DR: A patient with Werner's syndrome complicated by quintuplicate malignancy died of respiratory failure due to a brain tumor seven months after surgery, and the postmortem examination revealed a papillary carcinoma of the thyroid gland and a leiomyosarcoma of the lung.

The epiconus syndrome presenting with radicular-type neurological features.
TL;DR: The level of termination of the spinal cord was between T12 and L1-2 disc level, but most frequently at the middle portion of the L1 vertebra, which was on average 1.6±0.4 (mean±standard deviation) vertebrae distal to the epiconus lesions.
Differentiating and antitumor activities of 1α,25-dihydroxyvitamin D3 in vitro and 1α-hydroxyvitamin D3 in vivo on human osteosarcoma
TL;DR: This study apparently is the first demonstration that vitamin D3 metabolites have an antitumor and differentiating effect on human osteosarcoma cells in vitro and in athymic mice.
