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: history of present illness: the patient is a 59-year-old male with a history of adenocarcinoma of the colon with metastatic disease to the liver. he underwent a colectomy on a previous admission and has subsequently received chemotherapy of oxaliplatin, avastin and tarceva. he is now 6 weeks post chemotherapy and presented for resection of liver metastasis. his preoperative workup included multiple radiologic imaging which demonstrated no other malignancies, preoperative assessment which placed him at an acceptable risk for surgery. he presented to the holding area on the day of his operation. past medical history: hypertension, gastroesophageal reflux disease. past surgical history: includes a colectomy in , pre colectomy left ureteral stent. medications on admission: include celexa 10 mg p.o. daily, lisinopril 10 mg daily and protonix 40 mg daily. allergies: include oxaliplatin which caused hives during his chemotherapy course. social history: he quit greater than a year ago, but he use to smoke a pack a day. no etoh. no iv drug use. physical examination on presentation: his temperature was 98.3, heart rate was 80, blood pressure was 125/100, saturating 98% on room air. he was a well-appearing man in no acute distress. his heart was regular. his lungs were clear. his abdomen was soft and benign. no peripheral edema. laboratory data: his preoperative labs were unremarkable. radiologic and other studies: his ekg was sinus rhythm. hospital course: on the day of admission, the patient was taken to the operating room where he underwent a right hepatectomy. he tolerated this procedure well. the details of the operative report are outlined in dr. operative note elsewhere in the medical record. due to the length of the case, an extensive dissection, fluid resuscitation the patient was kept in the icu overnight intubated. his initial postoperative course was significant for relative hypotension. initially, this was thought to be due to under resuscitation and also an epidural catheter which was placed preoperatively. the epidural catheter was discontinued, and he was fluid resuscitated. his hemodynamics were normal. he required no pressor support, and his issues resolved over the first postoperative day. he was extubated on postoperative day #1, and his postoperative course after that has been unremarkable. on postoperative day #2, he was transferred to the floor. his diet was advanced. he received physical therapy and has been ambulating without assistance. all of his laboratory work has been within normal limits. at the time of discharge his lfts have trended down to an ast of 116, an alt of 224, an alkaline phosphatase of 171 and a total bilirubin of 1.7. he had a jp that was placed intraoperatively. this drainage appropriately decreased. prior to it being removed a jp bilirubin was sent which was 1.8. the patient is now ready for discharge to home. discharge diagnoses: 1. metastatic colon adenocarcinoma, status post right hepatectomy. 2. hypercholesterolemia. 3. hypertension. 4. gastroesophageal reflux disease. 5. blood loss anemia. medications on discharge: include lisinopril 10 mg p.o. daily, protonix 40 mg p.o. daily, percocet 1 to 2 q.4h. p.r.n. condition on discharge: good. discharge followup: the patient will follow up with dr. in his office in approximately 1 to 2 weeks. , procedure: cholecystectomy transfusion of packed cells lobectomy of liver diagnoses: esophageal reflux malignant neoplasm of liver, secondary unspecified essential hypertension acute posthemorrhagic anemia personal history of malignant neoplasm of large intestine 

Answer: The patient is high likely exposed to
