HISTORY:

This is a 66-year-old white man with a history of multiple myeloma diagnosed in June of 2003 when he presented with a skin rash and anemia. He has been seen and treated for his multiple myeloma at the
University of Arkansas Myeloma Institute. The patient has undergone tandem auto stem cell transplantation, first one in July and second one in October of 2003. He is in complete remission and no evidence of disease from a myeloma standpoint. He is scheduled for a planned consolidation chemotherapy consisting of DT-PACE q. three monthly times four doses. He was expected to receive this consolidation therapy within six months of his second auto transplantation. Following that, the treatment plan was to treat him with maintenance interferon therapy. During routine followup CT scans, he was found to have right lower lobe collapse and an endobronchial lesion was suspected. He underwent a diagnostic bronchoscopy which showed right endobronchial lesion. A biopsy revealed a possible neuroendocrine tumor and a Indium-111 Pentetreotide (OctreoScan) study was ordered.

PAST MEDICAL HISTORY:
Multiple myeloma as above.

PAST SURGICAL HISTORY:
Hernia repair, left inguinal repair in 1965.

FAMILY HISTORY:
Father died of lung cancer at 78.

SOCIAL HISTORY:
Two to three cigarettes per day for ten years. Drinks one beer and one shot of whisky per day. The patient has two grown children.  He is a retired schoolteacher.

REVIEW OF SYSTEMS:
He lost 25 pounds after transplantation. He has normal appetite.

IMAGING:
PET scan shows increased uptake in the right hilum

Nuclear Medicine:

5.4 mCi Indium-111 octreotide infused intravenously. At a 4 hour delay, planar images were obtained anteriorly and posteriorly over the thorax, abdomen, and pelvis. SPECT imaging of the lower thorax and abdomen was performed. Study was performed on the Hawkeye system with computed tomography attenuation correction and anatomic localization.

In the left upper quadrant just to the left of midline, a small focal are of increased activity is seen, which is localized in the bowel. A large mass is seen involving the right perihilar region, consistent with a known metastatic tumor. A second focus of increased activity is seen involving the left lateral chest wall at approximately the level of the seventh rib. Smaller discrete foci are seen involving the chest wall.

IMPRESSION: INDIUM-111 OCTREOTIDE STUDY DEMONSTRATING FOCAL AREA OF INCREASED ACTIVITY INVOLVING THE BOWEL IN THE LEFT UPPER QUADRANT. A LARGE METASTATIC FOCUS IS SEEN IN THE RIGHT HILAR REGION AND A SECOND SMALLER FOCUS IS SEEN INVOLVING THE LEFT LATERAL CHEST WALL. FINDINGS MOST CONSISTENT WITH PRIMARY AND METASTATIC CARCINOID.

Hospital Course:

He underwent a right lower lobectomy and right middle lobectomy. The pathology report indicated a mucinous adenocarcinoma with prominent neuroendocrine features, most likely primary.  His postoperative pathological diagnosis is consistent with stage III-A non-small cell adenocarcinoma. One subcarinal node was involved with malignancy. Hem/Onc is now consulted for recommendations regarding treatment of stage III-A lung cancer, status post surgical resection.

RECOMMENDATIONS:
1. We will coordinate with multiple myeloma oncologist to see if the patient can receive DT-PACE which will serve as an adjuvant chemotherapy to his lung cancer as well. After his first course of DT-PACE, we will recommend adjuvant radiation therapy to his chest to decrease local recurrence. A new adjuvant trial  this year shows 4% absolute survival advantage in patients who receive adjuvant cisplatin based therapy. In that study, many of the patients had received adjuvant radiation therapy also. In a separate study for patients with resected stage III-A lesions, adjuvant radiation therapy decreased local recurrences but did not affect the overall survival. Taking these studies into account, it is reasonable to recommend radiation therapy while incorporating his consolidation therapy for multiple myeloma with DT-PACE.
