[The efficacy of ethinylestradiol for castration-resistant prostate cancer].

Objective: We analyzed the efficacy of ethinylestradiol as estrogen therapy on Castration-resistant Prostate Cancer (CRPC).

Patients And Methods: The study was conducted on 14 patients who were diagnosed as having CRPC and who were being prescribed ethinylestradiol (1.5-2.

Painless acute pancreatitis associated with sorafenib treatment: a case report.

Sorafenib is a multikinase inhibitor that is used for the treatment of metastatic renal-cell carcinoma. We report the case of a patient with painless acute pancreatitis associated with sorafenib treatment. The patient was a 71-year-old man who had undergone surgery for left renal carcinoma and tumor thrombus in the inferior vena cava and right atrium (IVC-RA).

[Clinical study of upper urinary tract carcinoma].

Purpose: We retrospectively reviewed 107 patients of upper urinary tract carcinoma to determine the overall outcome, prognostic factors, frequency of subsequent bladder cancer and role of adjuvant therapy.

Materials And Methods: 107 patients of upper urinary tract carcinoma, who underwent surgical treatment at Sumitomo Hospital between January 1992 and June 2007 were reviewed. The Kaplan-Meier method and Cox's proportional hazard model were used.

[A case report of superior mesenteric artery syndrome after hand-assisted laparoscopic left nephrectomy].

A 65-year-old man with left renal cell carcinoma RCC underwent hand-assisted laparoscopic nephrectomy. He was discharged on the 8th hospital day, but 2 days later he was admitted to the hospital again because of vomiting and abdominal pain. Abdominal computed tomography (CT) showed a narrow space between the superior mesenteric artery (SMA) and aorta as well as distension of the proximal duodenum.

[Case of drug-induced colitis like ulcerative colitis during IL-2 therapy for multiple bone metastasis after operation of kidney cancer].

A 60-year-old man underwent retroperitoneal laparoscopic nephrectomy for left renal tumor (cT1bN0M0).The histopathological examination revealed Kidney cancer grade 3 pT1b. The following evaluations revealed multiple bone metastasis.

Four cases of advanced renal cell carcinoma with pancreatic metastasis successfully treated with radiation therapy.

We report four patients with pancreatic metastasis of renal cell carcinoma who were successfully treated with radiation therapy. The patients were one woman and three men with a median age of 55 years (range, 49 to 62 years) who underwent radical nephrectomy for primary renal cell carcinoma. The median interval from nephrectomy to the diagnosis of pancreatic metastasis was 129 months (range, 54 to 176 months).

[A case of retroperitoneal malignant fibrous histiocytoma with marked response to concurrent cisplatin and radiation therapy: a case report].

A 42-year-old male was referred to our hospital with a complaint of right lumbar pain in September 1999. Abdominal computed tomography and magnetic resonance imaging revealed a large retroperitoneal tumor adjacent to the aorta and the renal vessels. We judged that it was inoperable.

[Castleman's disease in the pelvic cavity].

Although Castleman's disease may occur in any lymph node of the body, it is the most commonly found in the thoracic cavity. Castleman's disease rarely occurs in the pelvic cavity and only 18 such cases have been reported. We report a case of pelvic Castleman's disease.

[A case of inflammatory myofibroblastic tumor of the bladder].

Here we report a rare case of inflammatory myofibroblastic tumor of the bladder. The patient was a 72-year-old man. We diagnosed this case preoperatively as urachal tumor from urine cytology, cystoscopy, and magnetic resonance imaging.

[Synchronous ipsilateral renal cell carcinoma and transitional cell carcinoma: report of 2 cases].

Two cases of synchronous ipsilateral renal cell carcinoma and renal pelvic transitional cell carcinoma are presented, one in a 70-year-old man and another in a 54-year-old man. These two cases were diagnosed preoperatively as synchronous ipsilateral renal tumor and pelvic tumor from urine cytology, retrograde pyelography, computed tomography and magnetic resonance imaging, and in both two cases, nephroureterectomy was performed. Pathological diagnosis was renal cell carcinoma and renal pelvic transitional cell carcinoma, which existed incidentally in the same kidney.

[A case of synchronous double primary cancers of prostate, and bladder in a hemodialysis patient: a case report].

A 60-year-old male, who had been maintained on hemodialysis for 4 years, visited our hospital to receive living renal transplantation. He complained of macrohematuria, and preoperative examination showed elevation of psostate specific antigen (PSA). Cystoscopy revealed papillary tumors on the right lateral bladder wall.

[Renal cell carcinoma with hydronephrosis due to pelviureteric junction obstruction: a case report].

A 57-year-old male was referred to our hospital with a complaint of dizziness. Abdominal computed tomography and retrograde pyelography revealed a left renal tumor associated with hydronephrosis due to pelviureteric junction (PUJ) obstruction. A radical nephrectomy was performed and histological diagnosis was renal cell carcinoma.

Cushing's syndrome with a large pituitary adenoma producing both corticotropin-releasing hormone (CRH) and adrenocorticotropin (ACTH).

A 57-year-old man showed high serum cortisol, plasma adrenocorticotropin (ACTH) and corticotropin-releasing hormone (CRH) levels with a large pituitary tumor and a prostatic cancer. High dose dexamethasone did not suppress cortisol secretion and CRH administration did not stimulate cortisol secretion. After surgical removal of the pituitary tumor, plasma CRH, ACTH and serum cortisol levels were normalized.
