A 61-year-old male underwent right partial nephrectomy for a pelvic tumor of a solitary kidney at the former hospital on April 1975. Two years later he had a small bladder tumor and transurethral resection was performed. Since August 1985 he had been followed up in our hospital. On June 1986, the urine cytology showed class V, but neither cystoscopy nor drip infusion pyelography revealed the tumor. On January 1992, he consulted our department with macrohematuria and anuria. Serum creatinine and blood urea nitrogen level were 17.24 mg/ml and 84.1 mg/ml, respectively. Hemodialysis was administered. Retrograde pyelography revealed a defect of tumor at the pyeloureteral junction, and pyuria by ureteral catheterization showed class V cytology. Abdominal CT showed right hydronephrosis caused by the recurrence of pelvic tumor, and right nephrectomy was performed. The histopathological diagnosis was non-papillary transitional cell carcinoma, grade 3 > 2, pT3. He is in good condition with maintenance hemodialysis. In the Japanese literature there were 16 cases of pelvic tumor on the solitary or residual kidneys. In 12 of the 16 cases, kidney sparing treatment was tried and only our case has lived over 10 years. The indication of partial nephrectomy for pelvis tumor was discussed.

Small bowel adenocarcinoma (SB-AC) is a very rare tumor entity. Epigenetic alterations, including hypermethylation of DNA mismatch repair genes and tumor suppressor genes, seem to be important for carcinogenesis in tumors of the gastrointestinal tract, but have not yet been investigated in SB-AC. In the current study, the prevalence of hypermethylation in a panel of genes involved in gastrointestinal carcinogenesis (hMLH1, HPP1, p14(ARF), p16(INK4A), APC) was determined in a series of SB-AC. Paraffin-embedded tumor samples from 56 patients with SB-AC who underwent surgical resection between January 1985 and December 2003 were investigated for hypermethylation by means of methylation-specific real-time PCR, and compared with our findings in a previously investigated series of 50 gastric adenocarcinomas. In comparison with adenocarcinomas of the stomach, SB-AC revealed a significantly higher rate of hypermethylation of HPP1 (86% versus 54%, p = 0.0003), p16(INK4A) (32% versus 10%, p = 0.0006), and a significantly lower rate of hypermethylation of APC (48% versus 84%, p = 0.0001). Hypermethylation of hMLH1 and p14(ARF) was present in 23% and 9% of SB-AC, respectively. Locally advanced tumor categories (pT3/4) showed a higher rate of hypermethylation of HPP1 (90%) than did early tumor categories (pT1/2 categories, 40%; p = 0.0036). This was also reflected by the correlation between the HPP1 hypermethylation and high UICC stage (p = 0.02). No correlation was found between hypermethylation and other clinicopathologic parameters such as age, tumor grade and nodal status. Our findings suggest that hypermethylation of hMLH1, HPP1, p16(INK4A) and APC is frequent in primary adenocarcinomas of the small bowel. The differences in the hypermethylation spectrum of small bowel and stomach cancer indicate significant epigenetic differences between these tumors.
