We report for the first time the possibility of weekly paclitaxel chemotherapy for a patient with advanced, nonresectable gastric cancer undergoing hemodialysis. A 50-year-old man with chronic renal failure due to bilateral polycystic kidneys, who had undergone hemodialysis three times a week for 5 years, presented with hematemesis in December 2004. Based on the diagnosis of gastric cancer with lymph node metastases, surgery was performed. On the 15th postoperative day, the patient was treated with chemotherapy using paclitaxel. Paclitaxel was administered at a dose of 60 mg/m2 as a 1 h iv infusion in 250 mL of saline. Hemodialysis was started 1 h after the completion of the paclitaxel infusion and was performed for 3 h. Paclitaxel was administered weekly on d 1, 8, and 15 on a 28-d cycle. The maximum plasma concentration of paclitaxel was 1390 microg/L. The area under the curve of paclitaxel was 4398.6 microg x h/L. Grade 2 leukopenia was encountered during the first cycle. The plasma concentrations of paclitaxel from 6 to over 24 h after the infusion were 0.01 to 0.1 micromol/L in our patient, and these concentrations have been shown to be effective on inhibiting the growth of gastric cancer cells without producing adverse side effects in the patient. The plasma concentration of paclitaxel was not influenced by hemodialysis. We conclude that the pharmacokinetics of paclitaxel is not altered in a patient with renal failure, and that weekly paclitaxel is a suitable treatment regimen for hemodialysis patients with advanced gastric cancer.

A 56-year-old woman, who had been receiving treatment for chronic renal failure, was admitted to our Department because of a tumor of the pancreas head and multiple liver masses diagnosed by abdominal CT scans. Gastroduodenoscopy revealed a tumor which had invaded the Vater's papilla; the lesion was histopathologically pancreatic adenocarcinoma. Due to the presence of multiple metastases to the liver, we therefore performed general chemotherapy after obtaining the patient's informed consent (IC). CPT-11 was selected as the carcinostatic agent because the patient suffered from renal failure. The initial dose of CPT-11 was 80 mg, and we thereafter made minor adjustments in the dosage depending on the occurrence of side effects. After four courses of the treatment, a CT scan revealed both the tumor of the pancreas head and the multiple liver masses to have almost completely disappeared. Our clinical results indicate that CPT-11 may therefore be a strong candidate for first-line chemotherapy for the treatment of pancreatic cancer, especially in patients with renal failure.

Cachexia is a common finding in various diseases such as chronic renal failure, HIV infection, malignancies, chronic obstructive pulmonary disease, congestive heart failure and rheumatoid arthritis. It is estimated that 30% of patients with malignancies will appear with cachexia, and up to 80% of patients with progressive metastatic disease will be affected. Cachexia is associated with decreased overall survival rates, and decreased beneficial effects of chemotherapy treatment. The underlying pathological processes in cachexia are not completely understood. It is believed that tumor necrosis factor alpha (TNFalpha) plays an essential rule in cachexia induction and propagation. This article reviews and discusses current anti-cachexia treatments, with special emphasis on anti-TNF-alpha treatment in malignancies and various other diseases.

To determine functional and oncological outcomes of nephron sparing surgery (NSS) for renal cell carcinoma (RCC). We identified from our kidney database 103 consecutive patients undergoing NSS for solid renal tumors in a solitary kidney. After excluding 17 patients (16.5%) undergoing NSS with palliative intent in presence of preoperatively diagnosed metastatic disease (n = 15) or positive lymph nodes (n = 2) and 6 patients (5.8%) who turned out to have benign tumors, the remaining 80 patients with RCC were analyzed. Mean follow-up is 8.0 years (range: 0.1-25.8). Mean tumor size was 4.2 cm (range 1.2-11 cm). Chronic renal failure requiring hemodialysis developed after NSS in nine patients (11.2%). In the remainder, serum creatinine was 1.72 mg/dl (range: 0.45-4.6 mg/dl) at latest follow-up. The cancer specific survival rates at 1, 5 and 10 years were 97.2, 89.6 and 76%, respectively. The estimated local recurrence free survival rates at 1, 5 and 10 years were 97.8, 89.4 and 79.9%, respectively. Univariate analysis of correlation between clinical and pathologic features with death from RCC showed significant associations for grading and tumor size. The long-term data of our series support the concept of organ-sparing surgery for RCC in a solitary kidney since it provides excellent local tumor control and cancer specific survival and preserves renal function renal function so that 89% of patients remained free of dialysis in the long-run.

From a critical review of series of patients on hemodialysis for chronic renal failure and operated for renal neoplasms, it appears there is a low incidence of metastases compared to series of patients operated for malignant renal neoplasms and who have not undergone hemodialysis. In patients on hemodialysis, there are various elements that can influence the diffusion of metastatic cells, such as cytokines, tumor necrosis factor-alpha, anticoagulants and bisphosphonates. However, particular reference must be made to the possibility of the dialysis membrane in the blocking or inactivation of tumor cells.

Synovial cell sarcoma (SCS) with metastasis to the regional lymph node was diagnosed in two cats. Synovial cell sarcomas are rare in cats and metastatic SCS has not previously been reported. In both cases, treatment consisted of limb amputation and adjuvant doxorubicin. Local tumour recurrence and pulmonary metastases were diagnosed in one cat 316 days postoperatively. This cat died of chronic renal failure 444 days after limb amputation. The second cat died of an acute pulmonary thromboembolism 41 days postoperatively without evidence of local tumour recurrence or metastatic disease.

Although prostate cancer is among the most frequent malignancies in the elderly, this tumor may be under-reported, and it seems that its socioeconomic burden is not well-estimated. Chronic urinary obstruction caused by the cancer may cause renal failure, with hemorrhagic tendency, neurologic disturbances, cutaneous disorders, and diverse fingernail changes. Black or brown nail pigmentation has been associated with benign and malignant conditions, including antineoplastic drugs' side effects, subungual metastases, and melanoma. Metastasis of fingernail melanoma can affect lymph nodes from the wrist to elbow and axillary regions. Coexistent melanonychia and wrist lump, mimicking melanoma with sentinel lymph node is reported. It is recommended to consider the differential diagnosis of nail changes due to chronic renal failure.

Myocardial metastasis from a cutaneous squamous cell carcinoma (SCC) is rare. Herein we have presented a case of metastasis from cutaneous SCC to the myocardium in a renal transplant recipient, which was confirmed by a cardiac fine-needle biopsy. Postmortem examination revealed disseminated metastatic disease involving myocardium, lungs, thyroid, skin, and peritoneum secondary to cutaneous SCC likely related to immunosuppression. At 46 years of age, he received a renal transplant for chronic renal failure caused by chronic glomerulonephritis. He started to develop multiple nonmelanoma skin cancers 4 years later. At least 23 invasive SCCs and 14 basal cell carcinomas were excised. His immunosuppressive regimen consisted of cyclosporine (150 mg), azathioprine (75 mg), and prednisone (10 mg daily), which was not modified despite multiple nonmelanoma skin cancers. Our case report further illustrates the potentially aggressive and fatal nature of cutaneous SCCs that can develop in organ transplant recipients. It argues for modification of the immunosuppressive regimen in such patients. The management of renal transplant patients with nonmelanoma skin cancers remains difficult and complex.

Acquired perforating dermatosis (APD) is a type of perforating disorder that is traditionally thought to be associated with diabetes, chronic renal failure, or occasionally liver disease. We report a case of APD in a patient with stage IV colon cancer with hepatic metastases. Although rare, APD associated with colon cancer is an important entity to consider; APD may be associated with a broader range of systemic diseases than previously recognized.

Epidermolysis bullosa is a group of inherited diseases that are characterized by skin and mucosal fragility and blister formation. A wide variety of extracutaneous manifestations can develop as well as various complications of the disease such as severe anemia, growth retardation, esophageal stenosis, mutilating deformities of hands and feet, glomerulonephritis leading to chronic renal failure, and many others. One of the most important and often occurring complications is the development of cutaneous squamous cell carcinomas that grow and metastasize quickly. The objective of this paper is to give dermatologists a review of major complications encountered in patients with epidermolysis bullosa. Since these complications occur so often and can be considered to be part of the clinical picture, it is mandatory to develop a multidisciplinary well-educated team involved in follow-up and treatment of these patients.
