[Long-Term Survival after Multidisciplinary Treatment for Resected Pancreatic Adenocarcinoma with Recurrence of Pulmonary Metastases - A Case Report].

Recent studies indicated that isolated pulmonary metastases could define a favorable subgroup in metastatic pancreatic cancer. We report a case of isolated pulmonary metastases after curative resection of pancreas head cancer treated with chemotherapy and pulmonary metastasectomy survived for 79 months after recurrence. A 72-year-old male underwent pancreatoduodenectomy for pancreas head cancer. Adjuvant chemotherapy was done with gemcitabine hydrochloride (GEM)for 6 months and then S-1 for 2 months. Twenty-seven months after surgery, 2 small metastatic nodules in the left lung was detected. Chemotherapy with GEM was performed but the lesions grew larger very slowly. A new metastatic nodule was detected in the right lung 40 months after surgery and pleural effusion was detected 52 months after surgery. Then combination chemotherapy with GEM and S-1 was performed for 3 months followed chemotherapy with S-1 alone. Seventytwo months after surgery, chemotherapy with GEM was performed again because of patient's intolerance to S-1. Ninety months after initial surgery, pulmonary metastasectomy of the right lung was performed because of its resistance to chemotherapy. Chemotherapy with GEM was started again 4 months after pulmonary metastasectomy but serum levels of tumor markers remained increase. Combination chemotherapy with GEM and nab-paclitaxel was started 8 months after pulmonary metastasectomy but the patient died 16 months after pulmonary metastasectomy.
