A 12-year Recurrence-free Survival After Multidisciplinary Treatment for a Patient With Combined Hepatocellular-Cholangiocarcinoma.

We report a 64-year-old woman with a 9-cm liver tumor in the left lateral section. The patient had neither hepatitis B or C virus infection, nor cirrhosis. Carbohydrate antigen 19-9 (CA 19-9) level was 1,889 U/ml. We also suspected bulky hilar lymph node metastasis, and a left lateral sectionectomy without lymph node dissection (R2) was performed. The pathological findings led to diagnosis of combined hepatocellular and cholangiocarcinoma. Three weeks post-operation, the patient underwent hepatic arterial infusion chemotherapy with cisplatin, fluorouracil, and mitomycin C. In addition, a total dose of 45 Gy of irradiation for the hilar lymph node was performed; while oral tegafur-uracil (UFT) has been administered for 10 years at a dose of 400 mg/day. The CA19-9 level of the patient was normalized after hepatectomy, hepatic arterial infusion, irradiation for hilar lymph node, and oral UFT administration. Currently, the patient is alive without any relapse for 12 years post-operation.

Number of Lymph Node Metastases May Indicate the Regimen for Adjuvant Chemotherapy in Patients with Stage III Colorectal Cancer.

BACKGROUND: Adjuvant chemotherapy (ACT) may prevent recurrence in patients with stage III colorectal cancer (CRC). However, only 10% of patients benefit from ACT and no effective indicators exist to predict which patients are likely to benefit. The present study validated metastatic lymph node (MLN) number as a new indicator for ACT. PATIENTS AND METHODS: We retrospectively reviewed 173 patients with stage III CRC, who were classified by Union for International Cancer Control (UICC) stage or N category, and analyzed their overall survival (OS) and disease-free survival (DFS) according to stage, number of MLNs and ACT use. RESULTS: Among 173 patients, we found 65 with only one MLN (N1a). For N1a patients treated with ACT, the 5-year OS rate was 100%; the 3-year DFS rate was 92.7% for those treated with oral ACT. CONCLUSION: The number of MLNs is a simple indicator for ACT in patients with stage III CRC. For patients with only one MLN, oral chemotherapy is a good option.

Acute Liver Failure Due to Regorafenib May Be Caused by Impaired Liver Blood Flow: A Case Report.

BACKGROUND/AIM: Regorafenib has been approved for treatment of patients with unresectable or recurrent gastrointestinal stromal tumors resistant to imatinib or sunitinib. However, regorafenib has severe side-effects, including acute liver failure. We describe the case of a patient with multiple liver metastases of a small intestinal stromal tumor who experienced acute liver failure while being treated with regorafenib. CASE REPORT: A 50-year-old patient with an unresectable small intestinal stromal tumor resistant to prior treatment with imatinib and sunitinib was started on regorafenib, but experienced acute liver failure 10 days later. Plasma exchange and steroid pulse treatment improved her liver function. During liver failure, abdominal ultrasonography showed to-and-fro flow in the portal vein. Lactate dehydrogenase concentration was markedly elevated to 1633 U/l. These findings indicate that liver failure in this patient was due to impaired liver blood flow. CONCLUSION: Regorafenib may impair liver blood flow, inducing acute liver failure.

Hyperthermia combined with chemotherapy for patients with residual or recurrent oesophageal cancer after definitive chemoradiotherapy.

BACKGROUND/AIM: Definitive chemoradiotherapy (dCRT) is frequently administered in oesophageal cancer. We carried out hyperthermochemotherapy (HCT) for residual or recurrent cases after dCRT for oesophageal cancer. The aim of this study was to elucidate the usefulness of salvage HCT for these patients. PATIENTS AND METHODS: Salvage HCT after dCRT was performed in 11 patients with residual or recurrent oesophageal cancer. We used an 8-MHz radiofrequency capacitive heating system for hyperthermia. The combined chemotherapy comprised of cisplatin/5-fluorouracil, an oral fluoropyrimidine and irinotecan. RESULTS: There were no severe adverse events caused by hyperthermia. Complete response and stable disease was achieved in three and five patients, respectively; symptoms were improved in the remaining three patients. The median survival time after HCT was 12 (range=3-88) months. CONCLUSION: HCT is a feasible and potent salvage therapy for patients with residual or recurrent oesophageal cancer after dCRT, unless salvage surgery is indicated.
