Forty-two patients with advanced testis carcinoma without previous chemotherapy were treated with VAB-4, and 41 were evaluable. The program consisted of three in-hospital inductions 16 weeks apart, and outpatient treatments every three weeks. Of the patients, 80% achieved complete remissions (CR). Chemotherapy alone induced CR in 61%, partial remissions (PR), in 24% and minor response (MR), in 15%. An additional 20% of patients (six PRs and 2 MRs) achieved CR following resection of residual tumor deposits. With a median follow-up of 27 months, the median duration of CR has not been reached. Of those achieving CR to chemotherapy alone, 12% had relapses. Bulk and extent of metastatic disease, histology of primary tumor, and tumor markers at the beginning of therapy influenced the frequency of CR. Of those with minimal disease, 90% achieved CR. The CR rate was 67% for those with advanced thoracic disease and 29% for those with advanced abdominal disease. Patients who had embryonal carcinoma and those who had no elevation of alpha-fetoprotein had a higher frequency of CRs. Myelosuppression with a leukocyte count drop less than 1000/mm3 occurred in three patients, and no patient had chronic renal failure or pulmonary fibrosis. One patient died from sepsis while in complete remission.

Wilms' tumor occurs in 5-10 % of all cases of nephroblastoma. The metachronous form represents 2-3 % of cases. Most (96.2 %) metachronous tumors appear within the first 5 years of the primary tumor. Associated malformations are more common in bilateral cases. Metachronous tumors are a therapeutic challenge. We describe the case of an 11-year-old girl with left hemihypertrophy. The diagnosis was metachronous relapse of Wilms' tumor 7 years after the first diagnosis. The patient received five courses of preoperative chemotherapy and tumorectomy was performed. Because of post-surgical complications, nephrectomy was performed on her only kidney. Since she is anephric, the patient is in chronic renal failure and is dependent on dialysis. Treatment with carboplatin and etoposide was continued after surgery and the patient is currently in complete remission. The appearance of a metachronous Wilms' tumor 5 years after that of the primary tumor is rare. When a contralateral tumour develops, chemotherapy must be given until the size of the tumor is reduced in order to preserve renal function and avoid dialysis. In patients with chronic renal failure caused by bilateral nephrectomy, ongoing treatment with dialysis support can be achieved through the choice of effective drugs and knowledge of their pharmacokinetics and pharmacodynamics.

Parathyroid carcinoma constitutes less than 1% of primary hyperparathyroidism. The exact etiology is not known. Prior radiation to neck, chronic renal failure and genetic factors are thought to play a role. The male to female ratio is one. Parathyroid carcinomas are slow growing, have a tendency to recur locally and metastasize late. 95% of parathyroid carcinomas are functioning. The major distinguishing features of malignant hyperparathyroidism are presence of a palpable mass in the neck and features of severe hypercalcemia. By far the most important test to diagnose primary hyperparathyroidism is serum level of Immunoreactive PTH. The diagnosis of primary hyperparathyroidism is essentially clinical and biochemical. Biopsy is not necessary before definitive surgery. CT scan appears to be the best investigation for detecting the primary tumor, its local extent and metastases. Most of the symptoms are attributable to hypercalcemia, which needs to be treated aggressively. Early surgery with 'en bloc' resection of the tumor is the only potentially curative treatment. Parathyroid carcinoma is traditionally said to be resistant to radiotherapy. Various chemotherapeutic agents have been used with partial anecdotal responses. The 5-year survival is about 50% and 10-year survival varies from 13-49%.

A 65-year-old man with positive anti-hepatitis C antibody and chronic renal failure was diagnosed as having a ruptured hepatocellular carcinoma (HCC) based on computed tomography (CT). The patient underwent transcatheter arterial embolization (TAE) for the HCC. After one more session of TAE, the patient underwent surgery. But HCC seeding peritoneally was pointed out. Vitamin K2 and vitamin E were administered as a conservative treatment. Six months after starting vitamins K2 and E, the primary tumor did not increase in size and intraperitoneal dissemination disappeared on CT with a significant decrease of alpha-fetoprotein. Even though this is only one case, combination therapy of vitamin K2 and E may induce growth suppression of HCC.

A 69-year-old woman who had been treated with hemodialysis for 16 months for chronic renal failure presented with a chief complaint of gross hematuria in March 2007. Cystoscopic examination revealed a non-papillary, pedunculated tumor located in the right wall of the urinary bladder. A transurethral resection of the bladder tumor (TURBT) was performed in September 2007. The pathological diagnosis was urothelial carcinoma clear cell variant. The patient is now apparently free of disease 20 months after TURBT. Urothelial carcinoma clear cell variant of the urinary bladder is a rare primary tumor, and this is the fourth case of urothelial carcinoma clear cell variant of the bladder to be reported.

We report favorable results achieved using a combination of cetuximab and radiotherapy to treat an elderly patient with advanced oropharyngeal cancer complicated by cardiovascular disease and renal dysfunction.The case was a 78-year-old man who was referred to our hospital with the chief complaint of pharyngeal pain and swelling of the right side of the neck. The patient was diagnosed with oropharyngeal cancer (T4aN2bM0) based on a cytological diagnosis of Class V squamous cell carcinoma and CT findings.Because the patient had a history of hypertension, chronic renal failure, diabetes mellitus, cerebral infarction, angina pectoris, and prostate cancer, we determined that surgical excision and chemoradiotherapy using platinum-based drugs would be difficult.We therefore treated the patient with a combination of cetuximab and radiotherapy. Grade 3 mucous membrane disorder and Grade 2 dermatitis were observed during the course of treatment, but the treatment was completed without any other adverse events.A contrasted CT image taken after the completion of treatment showed that the primary tumor and cervical lymph node metastases had disappeared and the patient thus achieved a complete response.As of 6 months after treatment, there has been no recurrence or metastasis.As shown in this case, combination therapy with cetuximab and radiotherapy can be curative even in elderly patients with advanced oropharyngeal cancer and numerous complicating conditions.
