A case of noninvasive ductal carcinoma arising in malignant phyllodes tumor.

We report on an exceedingly rare case of noninvasive ductal carcinoma arising in malignant phyllodes tumor of the breast. The patient was a 75-year-old woman who presented with a chief complaint of an indolent tumor mass of the left breast. Papillotubular carcinoma was diagnosed by aspiration cytology, and mastectomy with preservation of the pectoral muscle was subsequently performed (Bt+Ax+Ic, R2).

[A case of drug-induced interstitial pneumonitis after gemcitabine treatment for advanced pancreatic cancer].

A 54-year-old woman with advanced pancreatic cancer with peritoneal dissemination was given gemcitabine on days 1,8 and 15, and this was repeated on day 29 at a dose of 1,000-1, 150 mg/m2. After 5 courses,the total infusion was 20,900 mg. Thirteen days after the last infusion, she suffered from sudden dyspnea, and soon went into respiratory failure of WHO grade 4 with severe hypoxemia.

[A case of gastric adenosquamous carcinoma with abdominal paraaortic lymph node metastases successfully treated by TS-1 plus CDDP neoadjuvant chemotherapy].

A 62-year-old woman was admitted for anemia. An endoscopic examination revealed type 2 cancer from the upper body of the stomach to the antrum, and abdominal CT scan demonstrated enlarged abdominal paraaortic lymph nodes. The preoperative diagnosis was cStage IV gastric cancer (cT 3, cN 3, cH 0, cP 0, cM 0).

Pathological complete response to trastuzumab and paclitaxel in a patient with inflammatory local recurrence following breast conserving surgery.

We encountered a case of inflammatory local recurrence of breast cancer after breast conserving surgery which attained pathological CR after combination therapy with trastuzumab and paclitaxel. The patient was a 49-year-old premenopausal woman whose left breast cancer(T2N0M0)was treated by breast conserving surgery (Bp+Ax). The pathological diagnosis was scirrhous carcinoma, g, ly1, v0, t2, n0, ER (-), PgR (+) and stage I A.

[A case of peritoneal dissemination of gastric cancer successfully treated by irinotecan combined with cisplatin].

We report a case of a 59-year-old man with advanced gastric cancer. Distal gastrectomy with lymph node dissection (D1) was performed. Pathological staging was IV (T3N1CY1), and the operation resulted in curability C.

[A case of recurrent gastric cancer tolerant to TS-1 therapy successfully treated by TS-1 combined with docetaxel].

We report a case of a 58-year-old man with advanced gastric cancer producing sialyl-Tn antigen (STN). Total gastrectomy with distal pancreatectomy and splenectomy was performed. Pathological staging was IV (T 3 N 2 CY1), and most of the cancer cells were strongly positive for anti-STN antibody on immunohistochemical stainings.

Overexpression of the Wilms' tumor gene WT1 in colorectal adenocarcinoma.

Expression of the Wilms' tumor gene WT1 was examined in 59 cases of colorectal adenocarcinoma to examine the involvement of WT1 in tumorigenesis. Quantitative real-time reverse transcription-polymerase chain reaction (RT-PCR) showed that WT1 mRNA was expressed in the range from 7.2 x 10(-5) to 4.
