[A Case of Pancreatic Mixed Acinar-Neuroendocrine Carcinoma with Main Pancreatic Duct Development].

A 78-year-old man was referred to our hospital owing to a pancreatic tumor detected on ultrasonography. He showed weight loss, and his diabetes mellitus had worsened over 3 months. Abdominal contrast-enhanced computed tomography revealed a 3 cm diameter pancreatic head tumor with peripheral enhancement and a dilated pancreatic duct.

[Adenosquamous Carcinoma in the Remnant Pancreas after Pancreatoduodenectomy for Invasive Pancreas Cancer-A Resected Case with Five-Year Relapse-Free Survival].

A 52-year-old man underwent pancreatoduodenectomy(PD)for invasive cancer of the pancreatic head, with a histopathological diagnosis of moderately to poorly differentiated invasive ductal carcinoma. One year and 2 months after PD, follow- up CT revealed a mass 3 cm in diameter in the remnant pancreas without distant metastasis. Therefore, total remnant pancreatectomy was performed with a histopathological diagnosis of adenosquamous carcinoma.

[Severe Therapy-Related Pancytopenia Caused by UFT and LV in a Patient with Ascending Colon Cancer].

We report a case of a 79-year-old man who developed severe therapy-related pancytopenia from tegafur uracil(UFT)and Leucovorin(LV)as adjuvant chemotherapy for ascending colon cancer. Laparoscopic right hemicolectomy resection was performed for the ascending colon cancer. Pathohistological analysis revealed that the ascending colon tumor was moderately differentiated tubular adenocarcinoma(T3, N1, M0, and Stage III a).

[Lung Metastasis of Breast Cancer Five Years after Mastectomy - A Case Report].

The presence of a solitary lung tumor after radical surgery for breast cancer often causes difficulty in the diagnosis and treatment. We report a patient who had previously undergone radical surgery for breast cancer, and who underwent lung surgery. When the patient was 57 years old, she underwent surgical treatment for breast cancer.

[Analysis of the Risk Factors of Febrile Neutropenia Among 72 Women Receiving FEC in Early Breast Cancer Chemotherapy].

In early breast cancer chemotherapy, it is important to maintain the relative dose intensity(RDI). We retrospectively ana- lyzed the incidence and risk factors of febrile neutropenia(FN)among women receiving FEC(5-fluorouracil 500mg/m2, epirubicin 100mg/m2, and cyclophosphamide 500 mg/m2)chemotherapy. Of 72 patients, 33 patients developed FN and 39 patients did not.

[Predictors of Overall Survival after Locoregional Breast Cancer Recurrence].

We evaluated prognostic factors of locoregional breast cancer recurrence in 35 patients. The average age at the time of surgery was 58.4 years(range: 32-87 years).

[Treatment for Elderly Breast Cancer Patients Older than 80 Years].

Breast cancer is the leading form of cancer in women in Japan. Cases of elderly women with breast cancer have been increasing rapidly in Japan due to the increasing age of the population. We examined the clinicopathological features and prognosis of breast cancer patients over 80 years old to define an optimal treatment regimen.

[A Case of Resected Lymph Node Recurrence of Cancer of the Papilla of Vater].

We report the successful resection of lymph node recurrence of cancer of the papilla of Vater after pancreatoduodenectomy (PD). A 67-year-old man had undergone PD for adenocarcinoma of the papilla of Vater, and histopathological examination revealed well differentiated papillotubular adenocarcinoma, ly1, v0, T1, n (0), pStage ⅠB. One year after surgery, abdominal computed tomography revealed a mass at the left side of the residual inferior pancreaticoduodenal artery (IPDA).

[Examination of Resection for Pulmonary Tumors after Breast Cancer Surgery].

There are many arguments about whether surgical resection or drug therapy is better for pulmonary metastasis after breast cancer surgery. Here, we examine 9 cases of resection for pulmonary tumors suspected of being metastases from breast cancer, at our institution. The preoperative diagnosis was difficult, with nodules less than 20 mm in all cases.

[A case of liver metastatic recurrence of bile duct cancer completely responding to single-drug S-1 chemotherapy].

A 65-year-old man with common bile duct cancer was treated by pylorus-preserving pancreaticoduodenectomy with D2 lymph node dissection. Three months after surgery, tumor marker was increasing, and CT demonstrated multiple liver metastatic tumors. Single drug chemotherapy with S-1(100 mg/body/day)was administered.
