58 patients with advanced bladder cancer were treated with MVEC chemotherapy (methotrexate, vinblastine, epirubicin and cisplatinum). 22 patients suffered from locally advanced disease (pT3-4 M0 N0), in 20 patients regional lymph node metastases were found (pT3-4 N1-3 M0). In 16 patients distant metastases were noted (pT1-4 N0-1 M1). In 89% transitional cell and in 11% squamous cell cancer or anaplastic carcinoma was seen. Complete response was noted in 45%, partial response in 23% and no response in 32%. Tissue polypeptide antigen (TPA) was registered before each course of chemotherapy and 3 months after the last application. The sensitivity for (pT3-4 N0 M0) tumors was 90.9%, for (pT3-4 N1-3 M0) 100% and for tumors with distant metastases 100% also, overall 96.6%. No statistically significant different values between each tumor group were found. In 85.7% a concordant reaction of TPA values and clinical status was notable. In conclusion, TPA has been proven as a valuable and a reliable marker for monitoring therapeutic efficacy of chemotherapy for advanced bladder cancer.

The immunohistochemical study of tissue polypeptide antigen (TPA) was performed by Avidin-Biotin-Peroxidase complex method (ABC method) in the human bladder tumors. Thirteen bladder tumors (4 cases with transitional cell carcinoma grade 1, 6 cases with grade 2 and 3 cases with grade 3; 7 cases with pTa, 3 cases with pT1 and 3 cases with pT3) were subjected to this study. Prior to the experiment, it was confirmed that the TPA reactivity was not diminished by the tissue fixation with buffered formalin within 72 hours. Bladder tumors of grade 1 and 2 were strongly stained for TPA, whereas bladder tumors of grade 3 appeared to be stained weakly. There were no relationships between TPA stainings and the tumor staging, and between the TPA stainings and the prognosis of the patients. We have concluded that the TPA staining might be a useful method for determination of the bladder tumor grading.

The whole nucleotide sequence of pT3.2I, the smallest plasmid of the acidophilic bacterium Thiobacillus T3.2, has been determined. pT3.2I is 15,390 bp long with a 53.7% GC content. Different regions can be defined in it: one 2569-bp putative insertion sequence similar to other insertion sequences of some Agrobacterium Ti plasmids; and a longer sequence, which occurs in two almost identical copies, differing only in a 1-bp deletion (6406 and 6405 bp). Several open reading frames and some smaller sequences were found in this duplicated region: ORFA and ORFG, encoding a putative polyol dehydrogenase and a putative RepA replication protein, respectively, an 83-bp sequence which could code for an antisense RNA, and a 36-bp region highly homologous to ori sequences of ColE2- and ColE3-related plasmids. Another putative gene, ORFH, is only present in the longer copy of this region (it is deleted in the short copy) and might encode a 90-amino-acid polypeptide which could act as a second replication protein, RepB. Based on sequence comparisons, pT3. 2I can be related to plasmids in the pColE2-CA42 incB incompatibility group.
