RESUMEN
A 70-year-old woman was referred to our department due to a solitary mediastinal tumor which gradually grew near the site of anastomosis for 8 years after radical surgery of esophageal squamous cell carcinoma. It was difficult to distinguish the lymph node recurrence of esophageal cancer from another tumor of unknown primary origin. Endoscopic ultrasound-guided fine-needle aspiration was performed, and the tumor was diagnosed to be neuroendocrine carcinoma. She received concurrent chemoradiotherapy with etoposide plus cisplatin. After the completion of chemoradiotherapy, the tumor disappeared. A solitary growing tumor which develops after radical resection of cancer would be better to be examined histologically in order to make an accurate diagnosis and select the most appropriate treatment.

A 62-year-old man was referred to our department with suspected intussusception due to an ileal tumor. Tumor markers including soluble interleukin-2 receptor were not elevated. Contrast-enhanced computed tomography and color Doppler ultrasonography showed a distinct ileal tumor without intratumoral blood flow or surrounding lymphadenopathies. Retrograde single-balloon enteroscopy revealed a submucosal tumor in the ileum that was hard and ulcerated. Partial intestinal resection was performed, and the lesion was diagnosed as an inflammatory myofibroblastic tumor. The patient had no recurrence over 2 years without additional treatment after surgery. This rare tumor should be kept in mind as a cause of ileal intussusception in adult and a multidisciplinary approach is vital to characterize it.

A 69-year-old woman who had a history of chronic hepatitis C, autoimmune hemolytic anemia and myelodysplastic syndrome was treated with sorafenib at a daily dose of 400 mg for HCC with multiple lung metastases. Nonetheless, elevated serum tumor markers further increased (alpha fetoprotein from 121,100 to 348,660 ng/ml and protein induced by vitamin K absence/antagonist-II from 3435 to 29,357 mAU/ml), and lung metastatic lesions on chest X-ray showed no improvement after 2 months of sorafenib treatment. Sorafenib was discontinued because of adverse events with diarrhea, fatigue, and severe anemia due to bleeding from stomach telangiectasia. Hand-foot syndrome was mild. Thereafter, the tumor markers rapidly decreased to almost normal range, and the lung and liver tumors markedly shrunk and disappeared without any other cancer treatments. Her tumors remained in complete remission for 17 months until an intrahepatic recurrence occurred. This unique course of metastatic HCC indicated that antitumor mechanisms other than the direct anticancer effect of sorafenib contributed to tumor shrinkage.

Nanoparticle albumin-bound (nab)-paclitaxel has shown promising activity in advanced gastric cancer treatment. We herein report a case of advanced gastric cancer involving long-term management with a single administration of nab-paclitaxel. A 71-year-old man diagnosed with advanced gastric cancer with malignant ascites was treated with nab-paclitaxel as a second-line chemotherapy. He refused treatment continuation because of various severe toxicities in the first treatment cycle; he was therefore followed-up without any further treatments. Despite this, no disease progression was observed over 9 months. After progression, he received dose-dense paclitaxel, but he did not respond to this treatment and eventually died.
