You are a medical doctor specialized in cancer diagnosis. 
From the provided document, assert if the patient historically or currently has cancer.
For each condition, only pick from "YES", "NO", or "MAYBE". And you must following format without anything further. The results have to be directly parseable with python json.loads().

DISCHARGE SUMMARY

Patient Name: [Redacted]
Date of Admission: [Redacted]
Date of Discharge: [Redacted]

Hospital Course:

The patient was admitted to our hospital for jaundice and pruritus. Laboratory tests showed elevated blood markers, with a level of γ-glutamyl transpeptidase (γ-GTP) and total bilirubin. Additionally, the patient's serum carcinoembryonic antigen level was elevated. Computed tomography (CT) showed wall thickening in the second portion of the duodenum, dilation of the common bile duct, and swelling of the para-aortic lymph node. Upper endoscopy suggested a duodenal tumor. For obstructive jaundice, an endoscopic retrograde bile drainage tube was placed at the common bile duct. Further imaging with 18-fluorodeoxyglucose positron emission tomography (FDG-PET)/CT demonstrated abnormal uptake in the tumor in the duodenum.

The patient underwent chemotherapy with XELOX for six cycles to address the effectiveness of the treatment, which was followed by follow-up imaging with FDG-PET/CT or CT every 2 months. The imaging confirmed the disappearance of the metastatic liver tumor and nodal metastasis. The patient underwent pancreaticoduodenectomy with lymph node dissection and partial resection of the liver for curative intent, which showed that the lesions in the duodenum, liver, and 43 lymph nodes were not visible in the surgical specimen. Postoperatively, the histological effect was determined to be grade 3, and the patient was diagnosed as having achieved pathological complete response (pCR).

The patient suffered from grade A postoperative pancreatic fistula but was discharged from our hospital on postoperative day 32 without fatal complications. The patient received capecitabine orally for 6 months and has been disease-free for 14 months after the surgery with no evidence of metastatic lesion.

Diagnosis:
- Jaundice and Pruritus
- Duodenal Tumor
- Obstructive Jaundice

Treatment:
- Six Cycles of XELOX Chemotherapy
- Pancreaticoduodenectomy with Lymph Node Dissection and Partial Resection of the Liver

Follow-Up:
- Follow-up Imaging with FDG-PET/CT or CT Every 2 Months

Summary:
The patient was admitted to our hospital for jaundice and pruritus caused by a duodenal tumor. The patient underwent chemotherapy with XELOX for six cycles, which was followed by imaging that confirmed elimination of the liver and lymph node metastases. The patient then underwent pancreaticoduodenectomy with lymph node dissection and partial resection of the liver for curative intent. The patient recovered from surgery and achieved pathological complete response. The patient received capecitabine orally for 6 months and has been disease-free for 14 months after the surgery with no evidence of metastatic lesion.

 revealed no signs of metastasis.
