The distribution of hexamethylmelamine (HMM) was investigated in surgical biopsies from 12 patients with pelvic cancer who were given an oral dose of 200 mg at 2-24 hours before the operation. The highest concentrations of HMM were found in tissues, such as omentum and subcutaneous tissue, that have a predominant lipidic component. HMM concentrations in the primary tumor were lower than in other tissues and were similar to those in plasma. HMM concentrations in metastases appeared to be higher than in the primary tumor, and in metastases with a diameter less than 3 mm, drug levels were two to ten times those in larger ones. Plotting the HMM concentrations versus time, utilizing the data from different patients, the elimination half-lives were found to be 9.05, 8.82, and 8.53 in plasma, tumor, and subcutaneous tissue, respectively.

A 73-year-old man was admitted to the hospital complaining of gross hematuria and left flank pain. Abdominal ultrasonography and computed tomography revealed a left renal tumor with extracapsular extension. Laboratory data showed marked leukocytosis of 121,000/mm3 and hypercalcemia of 12.3 mg/dl without any findings of inflammatory disease or bone metastasis. Enzyme immunoassay of the serum demonstrated a high level of granulocyte colony-stimulating factor (250 pg/ml) and parathyroid hormone-related protein (1,069 pmol/l). Pathological diagnosis of needle biopsy specimen of the primary tumor was transitional cell carcinoma which was suspected to have originated from renal pelvis. Immunohistochemical examination with anti-granulocyte colony-stimulating factor monoclonal antibody demonstrated granulocyte colony-stimulating factor production in cancer cells. The patient underwent a course of systemic chemotherapy, but died two months after diagnosis. To our knowledge, this is the first report of renal pelvic cancer representing granulocyte colony-stimulating factor production and hypercalcemia simultaneously.

The patient was a 60 year-old male who first visited a doctor because of back pain on the right side in May 2003. As a result of thorough examination, he was diagnosed with right renal pelvic cancer (cT4, N2, M1), and was referred to our department for treatment. In spite of systemic chemotherapy and radiation therapy in combination with cisplatinum on the primary tumor were performed from May 2003 to December 2005, the number and size of hepatic metastases increased. Consequently, considering hepatic metastasis as the specific prognosis factor, the patient was given a total of 14 cycles of hepatic arterial infusion chemotherapy (HAIC) from January to October 2006. As a result, the hepatic metastases completely disappeared. Then HAIC was tentatively discontinued and the patient was followed up. However, as new lung metastases were found by CT in March 2007, radiation therapy was performed on the lung metastases. As hepatic metastasis was recognized again by CT in April 2007, HAIC was resumed and the patient was given a total of 6 cycles starting from May 2007. During that period, two transurethral resection of bladder tumor were performed against the recurrence within the bladder while transarterial embolization was performed against the bleeding in the right kidney. The patient was regarded as a long-term survivor surviving for about five years after his initial consultation.

A man in his 70s was referred to our hospital for further examination of a positive occult blood finding. Imaging studies showed that the patient had right renal pelvic cancer with interaortocaval, multiple paracaval and left supraclavicular lymph node metastases (cT3N2Ml). Induction chemotherapy was performed with 5 cycles of MEC (methotrexate/epirubicin/cisplatin) followed by 2 cycles of GT (gemcitabine/paclitaxel). After the combined chemotherapies, the residual lesions were the primary tumor in the right renal pelvis and the left supraclavicular lymph node. Right total nephroureterectomy combined with lymph node dissection of paraaortic, paracaval, and interaortocaval area and left cervical area were performed. Histopathologically the postoperative T stage of the primary tumor was determined as ypT3. As for lymph nodes dissected, an interaortocaval lymph node alone, but not the other nodes, contained viable cancer cells. Adjuvant chemotherapy was performed with 7 courses of GT therapy. The patient had intravesical recurrence once and received transurethral resection of bladder tumor followed by intravesical instillations of Bacillus Calmette-Guerin (BCG). Finally, the patient has been free from recurrence for 10 years after the final treatment.
