Case Presentation:
     This 63–year-old male patient, 陳 OO, was referred to us for radiotherapy assessment for
‘pancreatic tumor, suspect malignancy’.
      S:
           1. This patient suffered from upper abdominal discomfort for about 6 months and upper
               abdominal pain for about 2-3 months.
           2. In 2007/12, he came to LMC for ABD CT and only some abnormal finding on the
               pancreas was told.
           3. In 2008/03, he came to our hospital for further management, and abdominal sono
               reported a 5.5 cm mass over the pancreatic body.
           4. On 2008/03/12, you visited this patient and his wife in the ward.

           Histories: NDKA, no major medical disease history
           Review of systems: body weight loss in recent months, poor appetite, soreness of the frank
              and the back
     O:
          1. General Condition: ECOG: 1, ambulatory status, sitting on the bed, speech: OK
          2. Physical Examinations:
             (1). HEENT & SCF: no SCF LNs; (2). CHE: neg.; (3). ABD: mild tenderness over the
             upper abdominal region; (4). Back & Spine: no knocking pain over the back and spine;
             (5). Extremities: free movement; (6). Others: neg.
          3. ***Pathology: no definitive pathology report for the pancreatic mass.
          4. Images:
             (1). MRI of the brain in 2008/03: neg.
             (2). CXR in 2008/03: neg.
             (3). ABD sono in 2008/03: a 5.5*5.0 cm mass over the pancreatic body
             (4). ABD CT in 2008/03: a 5.6*5.0 cm mass over the pancreatic body with encasement
             of the celiac trunk, unresectable disease status; some small Lns over the peri-tumor
             region, size all less than 1 cm.
          5. Others: colon biopsy in 2008/03: tubular adenoma; CEA in 2008/03: 26.9; CA-199:
          pending result now

Questions & Discussions: (with potential answers)
(Please answer the following questions commented from your RT attending
    physician.)

    Q1: What are your findings/interpretations for the above key image(s)?
    A1: As described in the last attached page.


    Q2: What is your clinical cancer stage, according to the AJCC 2006, for this
       case?
    A2: clinical stage under clinical diagnosis only; strongly suggest histological diagnosis:
        cT4(unresectable; celiac trunk encasement)N1M0, stage III (2008/03, AJCC 2002)



    Q3: What is your pathologic cancer stage, according to the AJCC 2006, for
       this case?
    A3: no pathology stage can be defined in this case.


    Q4: What are your Oncology Diagnosis / Assessments for this case?
    A4: Oncology Diagnosis: Pancreatic body tumor (5.6*5.0 cm, CEA: 26.9, CA-199 pending,
        encasement of celiac trunk, unresectable disease status), suspect malignancy,
        cT4(unresectable; celiac trunk encasement)N1M0, stage III (2008/03, AJCC 2002)


    Q5: What is your Oncology Plan for this case?
    A5: Suggest Current Oncology Plan:
          (1). Further work-up studies: strongly suggest biopsy for histological diagnosis
          (2). Further treatments: definitive chemotherapy and radiotherapy after tissue proven



    Q6: What is your Radiotherapy Plan for this case?
       (Please reply with the following form: Indication/Contraindication, Goal, Target &
       Volume, Technique, and Dose & Fractionation.)
    A6: RT Plan may be designed as the following one:
         (1). Indication: RT is indicated for this patient after further tissue proven. If no any
         tissue proven can be obtained, RT may be indicated under currently clinical diagnosis
         after the patient and family agreed.
         (2). Goal: curative to potentially curative
         (3). Target & Volume: pancreatic mass with limited LN-drainage region
         (4). Technique: 3DCRT
         (5). Dose & Fractionation: 3960 cGy in 22 fractions to the initial large field then
         cone-down boost to gross tumor only up to total dose of 5040 cGy in 28 fractions.
