neoadjuvant and adjuvant radiation and chemotherapy for sarcoma indications
adjuvant radiation: (>5 cm) high Grade or low grade ( not confined to subcutaneous or intramuscular) Surgery alone: subcutaneous or intramuscular high-grade sarcomas smaller than 5 cm, or any size low-grade sarcoma, surgery alone should be considered if adequate wide excision with a good 1- cm cuff of surrounding fat and muscle can be achieved. chemotherapy depends on the histologic type of sarcoma. Neoadjuvant chemotherapy is almost always indicated for: Ewing's sarcoma–PNET rhabdomyosarcoma extremity sarcomas larger than 10 cm For patients with other histologic types of high-grade sarcoma, the role of chemotherapy remains controversial. neoadjuvant combination chemotherapy adult soft tissue sarcoma has several potential advantages, particularly for the treatment of locally advanced tumors: 1 It can make subsequent surgery easier. 2 It may treat micrometastatic disease early before the acquisition of resistance. 3 It leaves the vasculature intact for improved drug delivery. 4 It enables assessment of therapeutic response or resistance to therapy.

which type of endoleak should be addressed at once
type I-failure to seal the aneurysm
214
Endoleaks
I Inadequate seal at the proximal (Ia) or distal (Ib) attachment site Type I endoleaks are repaired as soon as they are discovered. These leaks rarely if ever close spontaneously. II Flow into the aneurysm sac from an aortic branch vessel (e.g., inferior mesenteric artery or lumbar artery) close observation with short interval serial imaging may be appropriate. III Endograft fabric tear or failure of seal between graft components Treatment with additional stents to cover the leak is indicated as soon as they are discovered to exclude the sac from systemic pressure. IV Endograft fabric porosity generally resolve spontaneously with reversal of anticoagulation. type V endoleak, endotension is the term for elevated aneurysm sac pressure leading to sac expansion in the absence of a radiographically documented endoleak.
