Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: right distal femur osteosarcoma status-post neoadjuvant chemotherapy. major surgical or invasive procedure: radical resection of osteosarcoma right distal femur and endoprosthesis reconstruction. dr. , dr. , dr. . assistants: dr. , dr. , dr. . history of present illness: the patient is a 26-year-old gentleman who presented with a huge osteosarcoma of his femur. it had an extensive soft tissue mass and was extremely painful at diagnosis. it extended from 7 cm below the lesser trochanter and probably extended into the knee joint. he also had metastatic disease. he was started on preoperative chemotherapy with some improvement of his pain, although the size of the mass did not change. we talked to him extensively with an interpreter about a recommendation for an amputation but he strongly preferred an attempt at limb salvage and given the fact that his prognosis was poor with his metastatic disease, it was elected to proceed with that. social history: denies history of tobacco, alcohol, or drug use. lives with his wife, no children. not currently working, but had previously worked in a restaurant. family history: non-contributory physical exam: afebrile with stable vital signs. voiding spontaneously. incision benign (clean, dry, intact). light touch sensation intact distally in superficial peroneal, deep peroneal, tibial distribution. 2+ dp and pt pulses. motor intact distally to extensor hallucis, tibialis anterior, and gastrocsoleus complex. pertinent results: 09:05am blood wbc-4.4 rbc-3.44* hgb-9.4* hct-28.6* mcv-83 mch-27.3 mchc-32.8 rdw-16.1* plt ct-1324* 09:15pm blood wbc-3.4* rbc-2.66* hgb-7.5* hct-21.2* mcv-80* mch-28.4 mchc-35.5* rdw-17.5* plt ct-417# 09:05am blood glucose-115* urean-4* creat-0.3* na-133 k-4.6 cl-99 hco3-30 angap-9 final pathology pending brief hospital course: mr. was admitted as noted above. he underwent the above procedure without complication. due to the vascular dissection required, dr. of vascular surgery assisted with the case. dr. assisted with the reconstructive portions of the case. his intra-operative blood loss was 1100cc and he received 5 units of packed red blood cells intra-operatively. he was extubated and taken to the icu at the conclusion of the case. he received an additional two units over the night following his surgery. on the morning of post-op day one he was deemed stable for transfer to the floor. he was initially tachycardic and febrile as high as 102.3, but this improved throughout his hospitalization. the anesthesia pain service assisted with his post-operative pain control while he had an epidural in place. he mobilized with pt non-weight bearing on his right lower extremity. he was converted from a posterior splint to locked at 30 degrees except for cpm and range of motion from 0-30 degrees on post-op day 2. his drain was discontinued and prophylactic ancef stopped 48 hours after surgery. on he was mobilizing well, had stable vital signs, was tolerating a regular diet, voiding spontaneously, had had a bowel movement and was deemed stable for discharge.
