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 78-year-old gentleman who had previously been diagnosed with esophageal cancer and had undergone chemotherapy with cisplatin and 5-fluorouracil and radiation therapy. he had a recent positron emission tomography scan which was found to be negative. when the patient initially presented, it was with an upper gastrointestinal bleed in which required 4 units of packed red blood cells. an esophagogastroduodenoscopy revealed esophagus with an 8-cm fungating distal esophageal adenocarcinoma. after this was the time in which the patient received his chemotherapy and radiation therapy. the patient presented to dr. for an esophagectomy for management of his esophageal cancer. pertinent laboratory values on presentation: in terms of preoperative laboratories, his white blood cell count was 6.4, hematocrit was 34, and platelets were 200. blood urea nitrogen was 16 and creatinine was 1.2. potassium was 4. pertinent radiology/imaging: positron emission tomography scan results as noted. physical examination on presentation: in terms of initial physical examination, the patient was in no acute distress. his sclerae were anicteric. there were no palpable lymph nodes in the neck in the supracervical or axillary region. his lungs were clear to auscultation bilaterally. his heart was regular in rate and rhythm. his abdomen was soft, nontender, and nondistended. his calves were nontender, and he had no edema. his pulses were in the upper and lower extremities. hospital course by issue/system: the patient was admitted on and underwent an esophagectomy by dr. , during which he had an estimated blood loss of 800 cc. otherwise, there were no intraoperative complications. intraoperatively, there was a finding of tumor at the gastroesophageal junction and firm celiac nodes, but no other evidence of metastasis. postoperatively, the patient was taken to the postanesthesia care unit where he was hypotensive. therefore, the patient was placed on a levophed drip. his postoperative hematocrit levels were 29.8 and 30; respectively. due to the fact that the patient required the levophed drip, he remained in the postanesthesia care unit on postoperative day zero and on postoperative day one. the patient had his epidural stopped, and he was transfused with 2 units of packed red blood cells. he was also given aggressive fluid hydration, as his blood pressure was thought to be secondary to his volume loss. the patient continued to have serial hematocrit levels followed which stabilized in the mid 20s. on postoperative day two, the patient developed some respiratory distress and was found to have a central venous pressure of 11. his oxygen saturations had dropped down into the 80s. he was treated with aggressive chest physical therapy and nebulizers treatment, but it was felt that this was likely secondary to volume overload as he was positive 7500 cc of fluid on postoperative day zero. his levophed drip had been weaned that day. his blood pressures were returning into the 150s/60s and at times also to the 180s. given the patient's respiratory status, he was transferred to the intensive care unit for closer monitoring. at the time of transfer to the intensive care unit; notably, his hematocrit was 27.6, and his blood urea nitrogen was 1.3, and his arterial blood gas was 7.3/47/89/24 and -3. his chest x-ray showed some left lower lobe collapse and consolidation which was stable and an unchanged right lower lobe opacity. while in the intensive care unit, the patient was again aggressively diuresed with intravenous lasix. his hematocrit remained stable and climbed to the upper 20s. the patient was continued on aggressive pulmonary toilet. by postoperative day four, the patient was otherwise clinically stable but continued to have some respiratory difficulties with a notable arterial blood gas of 7.4/45/125/29 and 2. he was started on tube feeds on this day. he subsequently underwent a barium swallow study which showed no abnormalities. by postoperative day five, the patient was doing quite well and was ready for transfer to the floor pending bed availability. notably, the patient did have occasional episodes of atrial fibrillation while in the intensive care unit which were treated with intravenous lopressor and did resolve. given the patient's problem with this, he was held in the intensive care unit on postoperative days five and six. these issues had resolved by postoperative day seven, and the patient had been diuresing well and his atrial fibrillation was controlled with metoprolol. he was started on a clear liquid diet. by postoperative day seven, the patient tolerated a clear liquid diet well. otherwise, the patient's chest tube was out by postoperative day eight. by postoperative day nine, the patient was doing well and was without complaints. he had remained afebrile. he was making good urine. his respiratory status was good. his abdomen looked soft and was nontender. his incision was clean. he was tolerating his tube feeds well. discharge disposition/condition: given that the patient was doing well in all these aspects, it was determined that he could be discharge to an extended care rehabilitation facility. medications on discharge: (the patient was discharged on the following medications) 1. roxicet elixir 5 cc to 10 cc by mouth q.4-6h. 2. ipratropium inhaler q.6h. as needed. 3. albuterol inhaler q.6h. as needed. 4. lopressor 75 mg by mouth three times per day (hold for a systolic blood pressure of less than 90). 5. colace 100 mg by mouth twice per day. 6. miconazole nitrate powder one application three times per day. 7. lansoprazole 30-mg suspension by mouth once per day. discharge instructions/followup: 1. the patient was instructed to follow up with dr. in 10 to 14 days. 2. the patient was also to follow up with his primary care physician. 3. the patient was instructed to follow up with dr. . 4. in terms of his tube feeds, he was to continue on his tube feeds at 100 cc cycled from 8 p.m. to 8 a.m. the patient was to continue on post gastrectomy diet with six small meals per day. his tube feeds were impact with fiber at full strength. , m.d. dictated by: medquist36 procedure: enteral infusion of concentrated nutritional substances partial esophagectomy open and other partial gastrectomy diagnoses: congestive heart failure, unspecified unspecified essential hypertension acute posthemorrhagic anemia atrial fibrillation malignant neoplasm of other specified part of esophagus conjunctivitis, unspecified
