Abstract
Cervical cancer is the seventh most frequent cancer worldwide but more than 80% of cases occur in developing countries. Till date, radiation therapy with external beam and brachytherapy remains as the core treatment for most stages of cervical cancer. However, radiation treatment protocols and equipment modelled on the best developed countries can be seldom applied directly to developing countries owing to financial constraints and lack of qualified personnel, thus, a substantial proportion of patients do not have access to even palliative radiation therapy. Treatment options when the standard therapy is either not available or difficult to reproduce in particular settings is highly desirable with the potential to save lives that otherwise could be lost by the lack of adequate treatment. These options of treatment ideally had to have show, 1) that these are not inferior to the "standard" in terms of either survival or quality of life; 2) that these can be delivered in settings were the "standard" is not available or if available its quality is poor; and 3) that the treatment option be accepted by the population to be treated. Based on these considerations, it is obvious that cervical cancer patients, particularly those who live in countries with limited resources and therefore may not have sufficient radiation therapy resources are in need of newer therapeutical options. There is now a considerable amount of information emanating from clinical studies where surgery has a major role in treating this disease. These forms of "radiation-sparing" treatments include total mesometrial resection that could make unnecessary the use of adjuvant radiation; neoadjuvant chemotherapy that could avoid the use of adjuvant radiation in around 85% of patients and preoperative chemoradiation that could make brachytherapy dispensable. The feasibility and therapeutical value of these potential forms of management need to be prospectively evaluated.

Abstract
The 30-45% failure rate after radical cystoprostatectomy mandates that we explore and optimize multimodal therapy to achieve better disease control in these patients. Cisplatin-based multi-agent combination chemotherapy has been used with success in metastatic disease and has therefore also been introduced in patients with high-risk but non-metastatic bladder cancer. There is now convincing evidence that chemotherapy given pre-operatively can improve survival in these patients. In this review we establish the need for peri-operative chemotherapy in bladder cancer patients and summarize the evidence for the efficacy of neoadjuvant chemotherapy. The advantages and disadvantages of neoadjuvant versus adjuvant chemotherapy are discussed, and the main shortcomings of both--treatment-related toxicity and the inability to prospectively identify likely responders--are presented. Finally, a risk-adapted approach to neoadjuvant chemotherapy is presented, whereby the highest risk patients are offered treatment while those unlikely to benefit are spared the treatment-related toxicity.

Abstract
Cancer of the urothelium is the fourth most common malignancy in men in the U.S. and the ninth most common in women. More than 63,000 Americans will be diagnosed with bladder cancer this year (47,010 men and 16,200 women), and more than 13,000 (8,970 men and 4,210 women) can expect to die of their disease. The approximate 5:1 ratio of incidence to mortality roughly parallels the frequency of superficial to invasive disease. Efforts to improve this ratio have generated a potential paradigm shift in the treatment of urothelial cancer, incorporating increasingly active chemotherapy into treatment regimens for high-risk tumors in both the pre-and postoperative settings. This review summarizes the evolution of chemotherapeutic treatment of urothelial cancer and the rationale for its perioperative administration and addresses the future directions of clinical research in this field.

Abstract
OBJECTIVES To determine whether the failure of chemotherapy in patients with regionally metastatic or unresectable transitional cell carcinoma (TCC) of the bladder can be predicted early in the course of chemotherapy with magnetic resonance (MR) imaging. METHODS In this prospective study, 36 patients with regionally metastatic or unresectable TCC of the urinary bladder underwent MR imaging before and after two, four, and six cycles of chemotherapy with Methotrexate, Vinblastine, Adriamycin (doxorubicin) and Cisplatin (MVAC). The response after two cycles of MVAC was evaluated by using conventional tumour size parameters with unenhanced MR imaging and with changes in the time to the start of tumour or lymph node enhanced at fast dynamic contrast-enhanced MR imaging. The results obtained with these techniques were compared with the findings at histopathology in cystectomy or transurethral resection specimens that were obtained after chemotherapy. Duration of survival was defined as the time from the start of chemotherapy until disease-specific death. Kaplan-Meier curves were drawn to determine the difference in prognosis between responders and nonresponders. RESULTS After two cycles of chemotherapy, the accuracy, sensitivity, and specificity in distinguishing responders from nonresponders with conventional MR imaging were 69%, 81%, and 50%, respectively. With the fast dynamic contrast-enhanced technique, accuracy, sensitivity, and specificity were 92%, 91%, and 93% respectively. The median bladder cancer specific survival was 28 months for all patients studied. Responders to chemotherapy at fast dynamic contrast-enhanced MR had better median disease-specific survival than nonresponders (42 months vs. 12 months [p<0.0001]). CONCLUSION We can predict whether a patient will respond to chemotherapy after two cycles of chemotherapy with fast dynamic contrast-enhanced MR imaging.

Abstract
Background Cisplatin-based chemoradiation is the standard of care for locally advanced cervical cancer patients; however, neoadjuvant modalities are currently being tested. Neoadjuvant studies in several tumor types have underscored the prognostic significance of pathological response for survival; however there is a paucity of studies in cervical cancer investigating this issue. Methods Four cohorts of patients with locally advanced cervical carcinoma (stages IB2-IIIB); included prospectively in phase II protocols of either neoadjuvant chemotherapy with 1) cisplatin-gemcitabine, 2) oxaliplatin-gemcitabine, 3) carboplatin-paclitaxel or 4) chemoradiation with cisplatin or cisplatin-gemcitabine followed by radical hysterectomy were analyzed for pathological response and survival. Results One-hundred and fifty three (86%) of the 178 patients treated within these trials, underwent radical hysterectomy and were analyzed. Overall, the mean age was 44.7 and almost two-thirds were FIGO stage IIB. Pathological response rates were as follows: Complete (pCR) in 60 cases (39.2%), Near-complete (p-Near-CR) in 24 (15.6 %) and partial (pPR) in 69 cases (45.1%). A higher proportion rate of pCR was observed in patients treated with chemoradiotherapy (with cisplatin [19/40, 47.5%]; or with cisplatin-gemcitabine [24/41, 58.5%] compared with patients receiving only chemotherapy, 6/23 (26%), 3/8 (37.5%) and 8/41 (19.5%) for cisplatin-gemcitabine, oxaliplatin-gemcitabine and carboplatin-paclitaxel respectively [p = 0.0001]). A total of 29 relapses (18.9%) were documented. The pathological response was the only factor influencing on relapse, since only 4/60 (6.6%) patients with pCR relapsed, compared with 25/93 (26.8%) patients with viable tumor, either pNear-CR or pPR (p = 0.001). Overall survival was 98.3% in patients with pCR versus 83% for patients with either pNear-CR or pPR (p = 0.009). Conclusion Complete pathological response but no Near-complete and partial responses is associated with longer survival in cervical cancer patients treated with neoadjuvant chemotherapy or chemoradiotherapy.

Abstract
PURPOSE In clinical cancer trials for evaluating neoadjuvant chemotherapy, tumor downstaging is frequently used as a surrogate end point for overall survival. We evaluated the surrogacy of tumor downstaging using data from a follow-up observational study in bladder cancer. EXPERIMENTAL DESIGN A total of 586 patients (from 32 Japanese hospitals) who underwent radical cystectomy for invasive bladder cancer (clinical T2 to T4) between 1990 and 2000 were analyzed. We considered changes over time in clinical stage at diagnosis and pathologic stage at cystectomy as a surrogate end point, and survival time after cystectomy as a true end point. First, we developed a new criterion for tumor downstaging. Second, we statistically evaluated surrogacy for the criterion using Prentice's criteria. RESULTS To develop the criterion of end points based on tumor downstaging, we selected the best classification among all possible classifications in an attempt to separate prognosis for patients. The hazard ratios after adjustment for prognostic factors in the intermediate effect patients and the poor effect patients were 1.9 (95% confidence interval, 1.0-3.7) and 5.0 (95% confidence interval, 2.6-9.8), respectively, compared with that in the good effect patients. The conditions for correlation and conditional independency of Prentice's criteria were satisfied approximately. Neoadjuvant chemotherapy has a statistically significant tumor downstaging effect, whereas there was no difference on survival between treatment groups. CONCLUSIONS The tumor downstaging effect could be an appropriate intermediate end point for screening novel neoadjuvant chemotherapy for invasive bladder cancer. The dataset from follow-up studies were useful for evaluating the surrogacy of end points.

Abstract
PURPOSE Neoadjuvant chemotherapy for invasive bladder cancer, involving a regimen of methotrexate, vinblastine, doxorubicin, and cisplatin (M-VAC), can improve the resectability of larger neoplasms for some patients and offer a better prognosis. However, some suffer severe adverse drug reactions without any effect, and no method yet exists for predicting the response of an individual patient to chemotherapy. Our purpose in this study is to establish a method for predicting response to the M-VAC therapy. EXPERIMENTAL DESIGN We analyzed gene expression profiles of biopsy materials from 27 invasive bladder cancers using a cDNA microarray consisting of 27,648 genes, after populations of cancer cells had been purified by laser microbeam microdissection. RESULTS We identified dozens of genes that were expressed differently between nine "responder" and nine "nonresponder" tumors; from that list we selected the 14 "predictive" genes that showed the most significant differences and devised a numerical prediction scoring system that clearly separated the responder group from the nonresponder group. This system accurately predicted the drug responses of 8 of 9 test cases that were reserved from the original 27 cases. Because real-time reverse transcription-PCR data were highly concordant with the cDNA microarray data for those 14 genes, we developed a quantitative reverse transcription-PCR-based prediction system that could be feasible for routine clinical use. CONCLUSIONS Our results suggest that the sensitivity of an invasive bladder cancer to the M-VAC neoadjuvant chemotherapy can be predicted by expression patterns in this set of genes, a step toward achievement of "personalized therapy" for treatment of this disease.

Abstract
Radical cystectomy is the standard treatment for patients with clinically localized muscle invasive bladder cancer, providing a 5-year survival rate of approximately 50%. Failure to cure is often due to the presence of occult metastases beyond the margins of local therapy, indicating a need for eradication of micrometastatic disease with systemic treatment, in order to improve survival. Combined chemotherapy regimens, such as methotrexate-vinblastine-cisplatin (CMV), methotrexate-vinblastine-cisplatin-doxorubicin (M-VAC) and gemcitabine-cisplatin (GC) have already demonstrated their effectiveness in patients with advanced or metastatic disease and have been considered as appropriate regimens in the peri-operative setting. Large randomized studies with a prolonged follow-up have been able to confirm a modest survival benefit with neoadjuvant therapy. A recent meta-analysis, including all previous reported randomized trials, concluded that neoadjuvant chemotherapy administration provides a significant survival benefit and can be administered without adverse outcomes resulting from delayed local therapy. Adjuvant chemotherapy trials, although promising, have failed to show statistically improved survival, mostly due to small sample sizes and absent or inconclusive data on overall survival. A multi-center randomized-controlled trial is currently ongoing, in order to elucidate the role of post-operative chemotherapy administration.

Abstract
AIM The presence of pelvic lymph node metastasis from bladder cancer has traditionally been associated with a very poor prognosis. The aim of this paper is to review the literature with regard to the management of patients with nodal disease, particularly gross nodal metastasis and suggest a strategy for management of these patients. METHODS We performed a literature search in the PubMed database and the reference lists of relevant papers describing the management of locally advanced bladder cancer. FINDINGS There are no randomised studies relating specifically to the management of nodal metastasis in bladder cancer. It is clear however that a significant number of patients with micrometastatic nodal disease may be cured. Few studies exist which address the management of patients with gross nodal disease and consist of series from a limited number of institutions. In patients with gross nodal disease detected pre-operatively or at the time of surgery, a multimodality approach consisting of surgery, chemotherapy and possibly radiotherapy seems appropriate. The prognosis of such patients relates to the pathological stage of the primary tumour and the degree of lymph node involvement. In addition a good response to neoadjuvant chemotherapy may identify patients who are likely to survive longer. CONCLUSIONS The prognosis for patients with gross nodal disease from bladder cancer is poor although cure may be possible in a small number of patients. In such cases a multimodality approach is appropriate and management decisions should be made on an individual patient basis.

Abstract
Neoadjuvant chemotherapy has been extensively investigated in muscle-invasive bladder cancer. When taken together, the randomized controlled trials of neoadjuvant cisplatin-based combination chemotherapy demonstrate an improved survival over cystectomy alone. In addition, neoadjuvant chemotherapy can result in downstaging of primary tumors. As noted, a pT0 disease status at cystectomy is associated with a significant improvement in survival. A randomized controlled trial comparing neoadjuvant to adjuvant cisplatin-based chemotherapy shows that neither approach is superior. Finally, the ongoing EORTC/SWOG adjuvant chemotherapy trial, when completed, should add importantly to the literature concerning the role of systemic chemotherapy in muscle-invasive bladder cancer.

Abstract
Radical cystectomy is the gold standard in the treatment of invasive bladder cancer. However, five-year disease-free survival is low most probably due to micrometastatic disease at the time of surgery. The neoadjuvant chemotherapy may be performed as the first line management for invasive bladder tumors in order to treat micrometastases found at the diagnosis and improve resectability of larger neoplasms. A total of 43 patients diagnosed with invasive bladder tumors and 11 patients received neoadjuvant chemotherapy. The mean age of patients was 64 (43-74) years, and mean follow-up period was 52 months (12-114). Neoadjuvant chemotherapy protocol consisted of methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) or cisplatin, methotrexate, and cisplatin (CMV). All patients in neoadjuvant chemotherapy group underwent radical cystectomy. There was no significant difference between the groups with respect to disease-free survival time and overall survival time. In patients who received neoadjuvant chemotherapy, the respective disease-free and overall survival times were 31 months and 36 months versus 30 months and 35 months in patients who were treated with surgery only (p > 0.05). Five-year survival rates were 36% and 31% in the chemotherapy and no-chemotherapy groups, respectively. In the present study, 5-year survival rate was not affected by neoadjuvant chemotherapy in invasive bladder tumor. Complete pathological remission (stage p0) was found in 28% and pathological downstaging (stage < T2) was seen in 9% of patients in the neoadjuvant chemotherapy group. Five-year survival rates were 75% and 14.2% in patients who responded to chemotherapy, and in patients with no response, respectively (p < 0.05). The most favorable prognostic factor in this study was the response to neoadjuvant chemotherapy revealed as complete remission or pathological downstaging. The most important issue remains the prediction of patients who would respond and benefit from neoadjuvant chemotherapy.

Abstract
Bladder cancer is the second most frequent tumour of the urogenital tract. Tobacco smoke has been shown to increase the risk of bladder cancer two- to fivefold as well as the exposure to metabolites of aniline dyes and other aromatic amines. Seventy-five per cent of bladder cancers are superficial at initial presentation, limited to the mucosa, submucosa, or lamina propria. Recurrence rates after initial treatment are 50-80%, with progression to muscle-invading tumour in 10-25%. In muscle-invading bladder cancers, there is a 50% risk of distant metastases. Surgery is the mainstay of standard treatment both in the form of transurethral endoscopic resection, mainly for superficial disease, and in the form of open ablative surgery with urinary diversion for muscle invasive disease. Endovesical administration of BCG has been employed after endoscopic resection as the most effective agent for both prophylaxis of disease recurrence and progression from superficial to invasive disease. The accepted treatment for muscle infiltrative disease is radical cystectomy. Response rates to combination chemotherapy regimens of up to 70% in patients with advanced metastatic disease have led to an investigation of its use for locally invasive disease in combination with conventional modalities of treatment.

Abstract
The relationship between clinical response to DNA-damaging drugs and p53 and p21 status in patients with locally advanced transitional cell carcinoma (TCC) of the bladder was assessed. The response to intraarterial chemotherapy (IAC) comprising 100 mg / m(2) of cisplatin (CDDP) and 40 mg / m(2) of pirarubicin (THP) and the prognosis were assessed in 23 patients (the mean follow-up period was 19 months). The p53 gene status of tumors was analyzed at exons 5 - 8 using polymerase chain reaction-single strand conformation polymorphism analysis in 19 patients, and paraffin-embedded tumor sections were immunostained for p53 and p21 in 23 patients. The overall objective response rate (incidence of good responders) was 70%. The negative p53 group (n = 17) showed a significantly higher objective response rate than the positive p53 group (n = 6) (82% vs. 33%; P = 0.045). The p53 gene status or p21 staining status was not significantly associated with responsiveness. When the p53 and p21 immunostaining results were combined, good responders were more accurately predicted than by p53 staining status alone; the negative p53 / positive p21 group (n = 12) showed an objective response rate of 92%, which was significantly higher than that of the positive p53 and / or negative p21 group (45%, n = 11) (P = 0.027). Cause-specific survival of the negative p53 group was significantly superior to that of the positive p53 group (P = 0.015). Negative p53 / positive p21 immunostaining is a possible predictor of favorable chemotherapeutic response in patients with TCC of the bladder.

Abstract
BACKGROUND The possibility of bladder preservation as well as the utility of neo-adjuvant chemotherapy for invasive bladder cancer are controversial issues. The purpose of this study was the evaluation of neo-adjuvant M-VAC chemotherapy and bladder preservation in patients with locally advanced transitional cell carcinoma of the bladder. PATIENTS AND METHODS Eighty-seven consecutive evaluable patients with T2-T4aNxM0 TCC of the bladder were treated with three cycles of neo-adjuvant M-VAC chemotherapy. After three cycles of M-VAC, 42 patients had TURB alone, 13 patients underwent partial cystectomy, and 32 patients were to undergo radical cystectomy. RESULTS Forty (51%) patients were T0 at the TURB following M-VAC. Thirty (71%) patients who had chemotherapy and TURB alone are alive; at a median follow-up of 54+ months (8(+)-109+). Twenty-four (57%) have maintained an intact bladder. Of 13 responding patients with monofocal lesions who underwent partial cystectomy, 8 patients (62%) are alive with a functioning bladder, at a median follow-up of 80+ months (16-107+ months). At a follow-up of 32 months (7-121+ months), 20 (63%) patients in the radical cystectomy group are alive. In patients who had downstaging to T0 or superficial disease, median follow-up is 55 months (10-121+ months) and five-year survival is 71%. Patients who failed to respond (T2 or greater after chemotherapy), at a median follow-up of 24 months (7-103+ months), had five-year survival of only 29%. CONCLUSIONS Bladder sparing in selected patients on the basis of response to neo-adjuvant chemotherapy is a feasible approach which must be confirmed in prospective randomized trials.

Abstract
BACKGROUND To evaluate the antitumor activity in patients with T3b, T4 or metastatic urothelial carcinoma treated with MEC or M-VAC chemotherapy, by performing a multi-center randomized prospective study. METHODS From 1991 to 1995, 89 patients with T3b, T4 or metastatic urothelial carcinoma were randomly allocated to a methotrexate, epirubicin and cisplatin chemotherapy group (arm 1: S-MEC therapy; n = 29), a dose-intensified MEC therapy combined with G-CSF group (arm 2: I-MEC therapy; n = 30) or a methotrexate, vinblastine, doxorubicin and cisplatin chemotherapy (arm 3: M-VAC therapy; n = 30). At the registration center, the patients were stratified into previously untreated patients and patients with recurrence after radical operation and then randomly allocated to the treatment groups. In each arm, two or more courses of chemotherapy (4-week cycles) were performed. RESULTS Of the 88 eligible patients, four treated with S-MEC therapy and two treated with I-MEC therapy showed CR. The response rates (CR + PR) were 52% (15/29) with S-MEC therapy, 76% (22/29) with I-MEC therapy and 47% (14/30) with M-VAC therapy. The response rate with I-MEC therapy was significantly higher than that with M-VAC therapy (P = 0.02). Although the incidence of leukopenia was low with I-MEC therapy, the incidence of thrombocytopenia was high with this therapy. CONCLUSION MEC therapy used in this study is promising in terms of the antitumor effects.

Abstract
In order to evaluate the efficacy of neoadjuvant chemotherapy in invasive urothelial carcinoma of the bladder a retrospective analysis was performed. 54 patients without distant metastases (T2-T3b, N0-X, M0) received 3 cycles of neoadjuvant chemotherapy according to the MVAC protocol (methotrexate, vinblastine, doxorubicin and cisplatin) after transurethral resection (TUR) followed by cystectomy. 52 patients had previously undergone cystectomy immediately after TUR. Complete histopathological remission was observed in 9 patients (17.3%) after TUR and in 17 patients (31.5%) after TUR+MVAC. Neoadjuvant MVAC resulted, therefore, in a 14% higher rate of complete remissions. The overall response to TUR was significantly improved by MVAC therapy. Downstaging by neoadjuvant chemotherapy was more readily achieved in initially low-stage tumours (T2: 44.4% and 30.8%, T3a: 47.1% and 19%, T3b: 5.3% and 5.5% in patients receiving TUR+MVAC and TUR alone, respectively). Overall survival did not differ significantly between both groups. Patients who were successfully downstaged to pT0 had a significantly better prognosis, and patients resistant to chemotherapy had the poorest prognosis, showing the shortest survival. In conclusion, histopathological response at cystectomy was improved by neoadjuvant MVAC chemotherapy after TUR and can be expected to be prognostically relevant in those patients who can be downstaged to T0, although overall survival failed to be significantly increased in this relatively small patient sample.

Abstract
The aim of this study was to examine prognostic factors for survival of patients with invasive bladder cancer who had received neoadjuvant chemotherapy followed by further treatment. From 1986 to 1990, 149 eligible patients with T3-4 N0-X M0 bladder cancer were entered into a phase II trial of neoadjuvant chemotherapy, consisting of cisplatin and methotrexate. Patients received two or four courses of chemotherapy, depending on the absence or presence, respectively, of a major clinical response after two courses. 136 patients were evaluable for clinical response after two courses of chemotherapy, and 75 patients were evaluable for pathological response after two or four courses. A multivariate analysis, based on pretreatment variables and the post-treatment variables, clinical response and pathological response, showed that performance status, tumour size and clinical response after two courses of chemotherapy were the only independent prognostic factors for all eligible patients. A second multivariate analysis in the selected subgroup of patients, who underwent a cystectomy, showed that the G-cagetory and pathological response were the only independent prognostic factors. In conclusion, in this group of patients, the response to chemotherapy was a strong and independent prognostic factor in addition to other independent variables. However, it was not accurate or strong enough to allow an impact on the choice of locoregional therapy.

Abstract
Thirty-three patients with muscle-infiltrating T2-T3a bladder carcinoma were treated by TUR through the full thickness of the bladder wall and extended into the perivesical fat. The solitary tumours were not more than 4 cm in diameter. Histology proved in every case tumour stages of pT2 (17 patients) or pT3a (16 patients), G2 or G3 transitional cell carcinoma and negative mucosal biopsies. After TUR the patients received 1 or 2 cycles of chemotherapy: 60 mg of doxorubicin, 50 mg of cisplatin, 1 g of 5-fluorouracil administered into the ipsilateral hypogastric artery. There was no perioperative mortality but one patient died of complications related to chemotherapy. During the first year of follow-up relapses of muscle-invasive cancer were observed in 3 patients (10%), two were subjected to cystectomy and one to repeated TUR. With a median follow-up of 34 months 27 patients are alive and have functional bladder. The actual 3-year and 5-year survival rates were 17/21 (81%) and 6/9 (67%), respectively. The results of this study suggest that in strictly selected patients extended TUR and intra-arterial chemotherapy may be a bladder-preserving treatment modality for muscle-invasive bladder cancer. Regular (three monthly cystoscopy, cytology, biopsy, CT) investigations and follow-up are necessary to detect recurrences.

Abstract
This retrospective study includes 534 patients who had curatively intended treatment for T2/T3/T4a bladder cancer at the Norwegian Radium Hospital during the period 1980-1990. Total cystectomy preceded by preoperative radiotherapy represented the treatment of choice in 263 patients (CysGr). High-dose radiotherapy was applied in 271 patients in whom total cystectomy could not be performed (RadGr). From 1985 neo-adjuvant cisplatin-based chemotherapy was increasingly used. The 5-year crude survival rate for all patients was 35% with 40% for CysGr and 22% for RadGr. In CysGr the 5-year survival rate was highest (63%) for patients with <pT2 and lowest for pN+ patients (13%). The following independent prognostic parameters were identified for the total group: T category, trial participation, treatment, creatinine, haemoglobin, age and time since initial diagnosis. No significant difference in survival was found when comparing the treatment results obtained before and after 1985. In spite of the introduction of multimodality therapy the treatment results for T2/T3/T4a bladder cancer have remained unchanged. However, subgroups of patients may benefit from this approach allowing bladder conservation in selected cases. More effective adjuvant regimens have to be developed for high-risk patients (pT3b/pN+).

Abstract
The recommended treatment for medically fit patients with muscle-invading bladder cancer is usually radical cystectomy. However, transurethral resection of the tumor, partial cystectomy, irradiation and systemic chemotherapy are each effective in some patients. These latter treatments allow bladder preservation and cure as an alternative to radical cystectomy although when used unselectively the survival rates are inferior to those of radical cystectomy. The updated results of conservative surgery, radiation therapy and systemic chemotherapy as monotherapy, as well as strategies of combined modality treatment were reviewed. Based on this review many areas of consensus were reached which include: 1. The primary goal of any treatment for a patient with muscle-invading bladder cancer is survival; bladder preservation in the interest of quality of life is a secondary objective. 2. Only a small proportion of carefully selected patients may be cured by transurethral surgery alone, or by partial cystectomy alone. 3. Radiation therapy is currently the standard bladder-preserving therapy against which all other bladder-preserving methods must be compared. 4. Systemic chemotherapy as monotherapy is inadequate and cannot be recommended. 5. The addition of cisplatin-containing systemic chemotherapy to radiation therapy or conservative surgery appears to improve local control. While no multi-modality therapeutic regimen has yet been shown to be clearly optimal with regard to local efficacy and minimizing toxicity, monotherapy for bladder preservation is probably not desirable as a routine approach. 6. Deferring the patient from immediate cystectomy does not appear to compromise survival, nor does the addition of primary systemic chemotherapy appear to significantly increase the morbidity of cystectomy or radiotherapy.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Clinical, endoscopic and pathological assessment provides the classical factors of prevision for bladder tumours. The risk of recurrence is different among primary and recurrent tumours. The risk of recurrence for primary tumours is correlated to the number of neoformations at diagnosis and to the cystoscopy at three months. The risk of recurrence for recurrent tumours is correlated to the number of neoformations and the previous recurrence rate. It seems that the number of recurrences doesn't imply a higher risk of progression. The most important endoscopic parameters are: number, shape and size of neoformations, and appearance of the vesical mucosa. The most important pathological parameters are: growth pattern, grade, stage, histologic aspect of the vesical mucosa and invasion of lymphatic vessels. All these parameters are correlated to the risk of tumour progression for groups of patients but they cannot predict the fate of the individual case. The predictive value of these parameters could improve with a critical revision of the definitions of grade and stage.

Abstract
Staging of transitional cell carcinoma of the bladder relies on an accurate assessment of the depth of tumor invasion within the bladder wall and surrounding structures. Fat adjacent to muscle invasive carcinoma is often interpreted to represent full-thickness invasion of the bladder wall with extension into the perivesical tissues. We present a case report highlighting our finding of significant regions of fat within the lamina propria of the urinary bladder and its clinical importance with respect to the overstaging of carcinoma of the bladder.

Abstract
Integrating systemic chemotherapy in the treatment of patients with invasive bladder cancer is essential to improve survival because the majority of deaths are from systemic relapse. However, as experience with invasive tumors evolves, it is clear that treatment recommendations need to be tailored to an individual patient based on metastatic risk and, ideally, sensitivity to treatment. For those with tumors that do not extend through the bladder wall, standard therapy remains radical surgery. Nevertheless, encouraging results are being reported with increasing frequency using strategies designed to preserve bladder function through a variety of means. Crucial to the recommendation of a specific approach for an individual is improving our ability to define prognosis prior to initiating treatment. Patients with a high risk of systemic recurrence generally require chemotherapy, although the optimal route of integration, pre vs. post-operatively, remains controversial. In those patients who require it, chemotherapy can be administered more safely with the concomitant administration of hematopoietic growth factors. These factors alone, however, are unlikely to improve overall survival. Crucial to the latter effort will be the identification of more active agents, improving our understanding of intrinsic and acquired resistance to chemotherapy, and better delivery of the chemotherapeutic agents currently available. Of equal importance, is the enrollment of patients in clinical trials. These can include large scale randomized comparisons with using a survival end-point, as well as new therapies in high risk populations. The latter would include patients with advanced T3b, T4 and N+ disease, with a high risk of metastatic failure, and low complete response proportions to presently available regimens.

Abstract
Transitional cell carcinoma of the urinary bladder has a poor prognosis, once the muscle layers of the bladder wall have been invaded, irrespective of whether operative or radiation therapy is chosen for local treatment. The main reason for this is probably the existence of disseminated micrometastases at the time of primary treatment. Thus, a combination of systemic and local treatment would seem logical. The present study reports the response to chemotherapy in 30 patients with muscle-invasive urinary bladder tumours and the findings at subsequent cystectomy. The chemotherapy comprised cisplatin, methotrexate and leucovorin rescue and was tolerated without any alarming side-effects or increase in perioperative morbidity or mortality. The complete response rate was 43% (13/30) and, in 27% (8/30), there was a partial response with conversion into a more superficial tumour stage. The total, beneficial response rate was thus 70%.

Abstract
BACKGROUND The role of total cystectomy was to be assessed in the curative treatment of muscle-invasive bladder cancer. METHODS Two hundred and fifty-three patients with T2-T4a transitional cell carcinoma of the urinary bladder were referred to precystectomy radiation therapy (46 Gy, 66 patients; 20 Gy, 187 patients). These patients represented approximately 20% of all patients developing muscle-invasive bladder cancer in Southern Norway from 1980-1990. The clinical T categorization was generally based on palpability and extent of the palpable bladder tumor assessed by the referring urologist. Twenty-six patients (10%) did not have total cystectomy, most often due to peroperatively demonstrated locoregional inoperability. Two or three cycles of cisplatin-based combination chemotherapy were given to 68 patients. RESULTS For the 227 patients who underwent cystectomy, the cancer-specific 5-year survival rate was 58% (T2 [104 patients], 63%; greater than or equal to T3 [123 patients], 54%) (P = 0.022). The comparable figure for patients with histologically proven regional lymph node metastases was 22%. The 97 stage-reduced cases (less than or equal to pT1) survived significantly longer than the 130 patients without stage reduction (74% versus 46%) (P < 0.0001). Neoadjuvant chemotherapy was correlated with a more favorable survival in patients with greater than or equal to T3 tumors but did not seem to influence survival of patients with T2 bladder cancer. CONCLUSIONS In a multicenter setting, prognostically relevant T categorization of operable muscle-infiltrating bladder cancer can be based on the palpability of the primary tumor. Approximately 50% of favorably selected patients with operable T2-T4 bladder cancer survived for at least 5 years independent of whether the operation was done at a large uro-oncologic unit or a smaller urologic section. In this retrospective review, chemotherapy seemed to improve the survival in patients with deeply infiltrating (greater than or equal to T3) bladder cancer but appeared to represent an overtreatment in patients with T2 tumors.

Abstract
BACKGROUND Based on the excellent results with combination chemotherapy such as M-VAC (methotrexate, vinblastine, doxorubicin, and cisplatin) in patients with advanced disease, neoadjuvant chemotherapy has been advocated to improve survival and in some cases to permit bladder conservation. METHODS A Phase II study of neoadjuvant M-VAC chemotherapy was performed in patients with T2-T4N0M0 bladder tumors. After clinical staging, three cycles of M-VAC were given. After patients underwent postchemotherapy clinical restaging, pathologic restaging (partial or radical cystectomy) was planned. RESULTS Forty-six patients are evaluable. A clinical response was attained in 78%. Six patients (13%) had stable disease, and four (9%) had progression. After chemotherapy, 17 patients underwent radical cystectomy, none of whom were pTO. In this group, 10 of the 17 (59%) are alive at a median follow-up of 37+ months (range, 8-62+ months). Eleven patients had a partial cystectomy; 7 of the 11 (64%) are alive, 6 (55%) with a preserved bladder. Eighteen patients had clinical restaging only, and did not have pathologic staging. Median follow-up for this group is 36+ months (11-65+ months). Twenty-one of the 29 (72%) patients managed with conservative surgery or transurethral resection of the bladder alone are alive with a functional bladder. Median survival for all patients has not yet been reached. Two-year survival is 82%, and 3-year survival is 70%. CONCLUSIONS The current study is of interest in terms of bladder conservation. Assessment of the true success of any bladder-preserving treatment will require longer follow-up.

Abstract
A total of 26 patients with locally advanced bladder cancer received chemotherapy consisting of cisplatin, methotrexate and vinblastine. Radical cystectomy was performed in 24 of 26 patients (92%) receiving neoadjuvant therapy, with a pathological complete response in 6 (23%) and pathological partial response in 1 (4%) for an overall response rate of 35% (95% confidence limits 17 to 56%). The overall median survival time is currently undefined. Of the patients 15 (58%) are alive with a median followup of 48.6 months. Response rates from this neoadjuvant chemotherapy appear to be similar to those reported with methotrexate, vinblastine, doxorubicin and cisplatin, and may represent a therapeutically equivalent regimen but neither may be curative in the majority of the patients.

Abstract
Radical cystectomy is the standard of care for patients with muscle-invading transitional cell carcinoma of the bladder. More limited surgery is only useful in highly selected patients and radiation therapy alone gives overall local-control rates under 40%. Phase II studies have shown that when radiation and trans-urethral surgery are combined with cis-platin based chemotherapy local-control rates increase such that the majority of patients preserve a tumor-free functional bladder. Up to 85% of patients selected for bladder sparing therapy on the basis of their initial response to chemo-radiation may keep their bladders. This figure could increase further when other powerful prognostic factors such as the presence of hydronephrosis, the presence of carcinoma in situ, and DNA ploidy are also taken into account in initial patient selection. The activity of cisplatin combinations in metastatic disease is not in doubt with up to 50% response rates generally reported. The hope that this will translate into the eradication of micrometastatic disease (known to be present in up to 40% of patients at diagnosis) has yet to be borne out. Those randomized trials so far reported have not shown any survival advantage when combined-modality therapy is compared to radiation alone. The addition of combination chemotherapy to radiation does not increase bladder morbidity but carries a considerable systemic penalty. Thus, despite promising Phase II studies, until local control and survival benefit is proven in a randomized trial it should continue to be regarded as experimental.

Abstract
DNA ploidy and S-phase fraction (SPF), determined by flow cytometry were studied in 118 patients with muscle-invasive transitional cell carcinoma (TCC) of the urinary bladder, scheduled for cystectomy after pre-operative radiotherapy (20 Gy/1 week) with or without systemic cisplatin-based neo-adjuvant chemotherapy. The correlation between these parameters and immunohistochemically demonstrated p53, c-erbB-2 and HCG was also investigated. There were 16 DNA diploid and 102 DNA non-diploid tumours. DNA ploidy was not related to the T (all 118 patients) or pN (58 patients) category, occurrence of stage reduction or cancer-related 5 years survival. Patients with high SPF tumours tended, however, to have a better prognosis than those with low SPF TCC reaching the level of significance (P < 0.05) for those patients who had high SPF tumours and received neo-adjuvant chemotherapy. Fifty-one of the tumours were p53 positive. p53 positive tumours were significantly more often found in TCC with low SPFs than in those with high SPFs. Respectively 12 and 9% of the tumours were HCG and c-erbB-2 positive, without correlation to DNA ploidy or SPF. We conclude that DNA ploidy does not represent a prognostic parameter in muscle-invasive operable bladder carcinomas. A high SPF, determined by FCM, may be helpful to identify patients with chemotherapy-sensitive TCC of the urinary bladder.
