Isolated limb infusion with doxorubicin is a simple and safe method of regional chemotherapy. The addition of preoperative external beam irradiation helped to increase the rate of limb salvage in patients with large and/or high-grade soft tissue sarcomas of the extremities.

initial responses of 43 patients treated by irradiation were followed using the assay. RESULTSThe NMP marker was identified in the urine of patients with bladder cancer at 52 kDa (NMP-52) by Western blot. The dot-ELISA detected the urinary NMP-52 marker in 92% of patients with squamous cell carcinoma, 98% with transitional cell carcinoma, and all six of those with adenocarcinoma of the bladder, with a specificity of 94%. The positive and negative predictive values (97% and 94%, respectively) and efficiency (96%) of the dot-ELISA were high. In addition, the NMP-52 tumour marker was not detected in the urine of patients who showed a response after radiotherapy. CONCLUSIONDetecting the urinary NMP-52 marker using dot-ELISA would be helpful in the rapid diagnosis and follow-up of patients with bladder cancer.

This trial compared 6 cycles of fluorouracil, epirubicin, and cyclophosphamide (FEC) with a sequential regimen of 3 cycles of FEC followed by 3 cycles of docetaxel (FEC-D) as adjuvant treatment for women with node-positive or/and T3 or T4 breast cancer. Between January 2006 and January 2010, 657 patients with operable breast cancer were randomly assigned to either FEC every 21 days for 6 cycles, or 3 cycles of FEC followed by 3 cycles of docetaxel, both given every 21 days. Radiotherapy was mandatory for all patients who had undergone breast conserving surgery. Radiation to the chest wall, supraclavicular area, was recommended following mastectomy. Hormone-receptor-positive patients received tamoxifen for 5 years after chemotherapy. The primary end point was 5-year disease-free survival (DFS). Median follow-up was 61 months. Five-year DFS rates were 74 % with FEC and 78 % with FEC-D (P = 0.013). Multivariate analysis adjusted for prognostic factors showed a 17 % reduction in the relative risk of relapse with FEC-D. Five-year overall survival rates were 85 % with FEC and 89.4 % with FEC-D, demonstrating a 27 % reduction in the relative risk of death (P = 0.014). The incidence of grade 3-4 neutropenia, the need for hematopoietic growth factor, and incidence of nausea/vomiting were higher with FEC. Docetaxel was associated with more febrile neutropenia, stomatitis, edema, and nail disorders. Though rare overall, there were fewer cardiac events after FEC-D, attributable mainly to the lower anthracycline cumulative dose. Sequential adjuvant chemotherapy with FEC followed by docetaxel significantly improves disease-free and overall survival in node-positive or/and T3 or T4 breast cancer patients. Although the magnitude of the benefit observed with FEC-D, differences in the toxicity profiles of FEC and FEC-D may influence the choice of treatment for patients.

We have developed an office-based dot-EIA for the detection of a urinary high molecular weight cytokeratin (CK). Immunohistochemical staining and western blot based on CK1K10 monoclonal antibody were used to identify the CK. Urine of 192 patients with different types, grades, and stages of bladder tumor and 72 controls were evaluated using dot-EIA. An intense and diffuse cytoplasmic reaction was shown in bladder squamous cell carcinoma. The target epitope was identified in urine at 65, 56, and 40-kDa. The CK purified from urine showed single polypeptide at 65-kDa using SDS-PAGE and single peak at 7.4 min using capillary zone electrophoresis. The dot-EIA detected the CK with high sensitivity (97%) and specificity (94%). The CK was not detected in urine of bladder cancer patients showing response to radiotherapy. The sensitive and specific office-based detection of urinary cytokeratin would be helpful in rapid diagnosis and follow up of bladder carcinoma.
