For standard chemotherapy in urothelial cancer we have a high level of evidence by several randomized phase III trials. They showed that MVAC was better than CISCA and Cisplatin monotherapy; that Gem/Cis was about as effective as MVAC, but less toxic; that HD MVAC+GCSF provided no statistically significant improvement in OS over standard MVAC, but significantly more CR and a longer PFS. And finally MVAC was better than 5FU/ IFN/ Cisplatin and the newest doublet Cisplatin/Docetaxel (this advantage was more pronounced because of an imbalance of performance status in favor of MVAC). Seven year update of an EORTC phase III trial of high-dose intensity M-VAC chemotherapy and G-CSF versus classic M-VAC in advanced urothelial tract tumours C.N. Sternberg*, the EORTC Genito-Urinary Cancer Group A B S T R A C T EORTC protocol 30924 is an international randomized trial reporting a 7.3 year update of a 2 weekly regimen of high-dose intensity chemotherapy with M-VAC plus granulocyte colony stimulating factor (HD-M-VAC) compared to classic M-VAC in advanced transitional cell carcinoma (TCC). Two hundred and sixty three untreated patients with bidimensionally measurable TCC were included. In an intention to treat (ITT) analysis, there were 28 complete responses (CR) (21%) and 55 partial responses (PR) (41%), for an overall response rate (RR) of 64% on the HD-M-VAC arm. On M-VAC, there were 12 CR (9%) and 53 PR (41%), for an overall RR of 50% .The P-value for the difference in CR was 0.009; and for RR, was 0.06. After a median follow-up of 7.3 years, 24.6% are alive on the HD-M-VAC arm vs. 13.2% on the M-VAC arm. Median progression-free survival was better with HD-MVAC (9.5 months) vs. M-VAC (8.1 months). The mortality hazard ratio (HR) was 0.76. The 2-year survival rate for HD-M-VAC was 36.7% vs. 26.2% for M-VAC. At 5 years, the survival rate was 21.8% in the HD-M-VAC vs. 13.5%. Median survival was 15.1 months on HD-MVAC and 14.9 months on M-VAC. There was one death from toxicity in each arm; and more patients died to malignant disease in the M-VAC arm (76%) than in the HD-M-VAC arm (64.9%). With longer follow-up initial results have been confirmed, and shows that HDM- VAC produces a borderline statistically significant relative reduction in the risk of progression and death compared to M-VAC. 2005 Elsevier Ltd.

Systemic chemotherapy is the only modality that has been shown in phase III trials to improve survival in responding patients with advanced bladder cancer [2,3] The M-VAC (methotrexate, vinblatine, adriamycin and cisplatin) regimen, first reported in 1985 at Memorial Sloan Kettering Cancer Center (MSKCC), revealed that urothelial carcinoma was sensitive to chemotherapy [4]. Patients with measurable lesions were found to have a 72% response rate (RR) and 36% attained a complete response (CR) [5]. Longterm survival was achieved in patients who attained CR. Overall survival for the entire population was 13.1 months. 0959-8049/$Stratification was according to the treating institution and WHO performance status. The main endpoint of the phase III trial was overall survival. Secondary endpoints included progression- free survival, time to progression, response rate and toxicity. The objective of the trial was to detect a relative difference of 50% in median overall survival between the two arms from 12 months to 18 months (hazard ratio = 0.67). This corresponds to an absolute difference of 13% at the time of the median. With a two-sided logrank test at the 5% significance level and 80% power this objective required 192 events (deaths). All analyses were carried out according to the intent-totreat principle and statistical significance was claimed at the two-sided 0.05 level. Time to event comparisons were performed using the logrank test. Estimation of survival curves was by the Kaplan–Meier technique. Comparison of distribution of binary and non-ordered categorical variables was performed using the v2 test and that of continuous variables using the Wilcoxon Rank Sum test. Comparison of ordered categorical variables was performed using a v2 test for linear trend.
Only in the post-hoc analysis of the bladder primary patients of this study was the difference significant . Only in the post hoc analysis of the bladder primary patients in this study, this difference showed statist significance.
Based on evidence in breast cancer and hematologic malignancies, the concept of dose dense and sequential chemotherapy was also explored in urothelial cancer by the „Memorial“ group. The sequence of adriamycin, gemcitabine followed by ifosfamide, paclitaxel, cisplatin in patients fit for cisplatin showed high response rates, but considerable toxicity. In patients with a good performance status but impaired renal function, the sequence of adriamycin/gemcitabine followed by paclitaxel/carboplatin was feasible with a good drug delivery ratio. A phase III trial will have to show the real potential of this concept. Summary: AG-ITP: toxicity AG-TC: feasible, randomized trials needed. Galsky, Cancer 2007: Good dose density/ drug delivery; Patients received treatment with sequential doublets of doxorubicin 50 mg/m2 administered by intravenous (i.v.) infusion plus gemcitabine 2000 mg/m2 administered i.v. every other week 5 cycles followed by paclitaxel 65 mg/m2 i.v. plus carboplatin AUC 1.7 i.v. weekly 12 cycles. Milowsky, JCO 2009: The conclusion that more chemotherapy is not necessarily better chemotherapy has been borne out in the recently reported randomized trial in which GC was compared with paclitaxel, cisplatin, and gemcitabine; a higher overall response rate for paclitaxel, cisplatin, and gemcitabine did not translate into improved progression-free or overall survivals.26 In exploratory subgroup analyses, a benefit was seen for patients with bladder primaries who received triplet therapy, and the benefit of triplet therapy appeared to be limited to patients with zero or one risk factor. Thus, more intensive chemotherapy does not appear to be associated with an improvement in survival for the entire patient population; however, subgroups who do derive a benefit may exist.
There are clear limits of conventional chemotherapy. Let me cite J. Bellmunt who put it in a nutshell : We „squeezed it out“. So far no improvement in survival was achieved beyond 13-15 months and 10-15% long-term disease free survival with newer triplets, 4-drug-regimen, dose-dense - sequential chemotherapy.
We will be more and more confronted with comorbidity in our patients because age and comorbid conditions are clearly connected and the frequency of invasive cancers is expected to rise mainly in pts aged 65 and above. Projected change in frequency of invasive cancers in the United States by age and sex. Nonmelanoma skin cancers were excluded from projections. Data adapted.7
With increasing age, the number of comorbid illnesses increases. In a study of 7,600 patients older than 55 years with cancer, those age 55 to 64 had an average of 2.9 comorbid conditions compared with patients age ≥ 75, who had an average of 4.2 comorbid conditions. 59 has important prognostic implications. An observational cohort study including 17,712 patients receiving care for multiple cancer types suggested that the severity of comorbidities affected overall survival (OS) in a dose-dependent fashion, independent of cancer stage. 4 When formulating a treatment plan, oncologists juxtapose the risk from the malignancy against that of comorbid illness on life expectancy. The effect of treatment in decreasing this risk is also weighed. Utilizing this framework, indolent cancers may be managed more conservatively in the setting of a substantial comorbid disease that is more likely to have an impact on life expectancy. In contrast, more aggressive malignancies warrant cancer therapy if they are more likely to affect life expectancy than the comorbid illness. In practice, it appears that weighing risks of does take place, albeit in the absence of firm guidelines. The presence and extent of appears to impact surgical decision making in oncology, such as the use of axillary dissection, radical prostatectomy, and resection for breast, prostate, and lung cancer, respectively. 60 – 62 Similarly, appears to affect utilization of chemotherapy across multiple malignancies. 63 – 65 It is possible that the latter trend reflects studies suggesting greater chemotherapy-related toxicity among patients with , 66 , 67 although conflicting data does exist. 68 Specific comorbidities may have a unique bearing on prognosis and treatment outcome. In a series of 5,077 patients treated with neoadjuvant hormone therapy followed by radiation for localized prostate cancer, use of hormone therapy was associated with a higher risk of all-cause mortality in the presence of coronary artery disease, congestive heart failure (CHF), or prior myocardial infarction (26.3% v 11.2%; P = .04). 69 In contrast, no increased risk of mortality was observed in men without or with only one coronary artery disease risk factor. Other studies have investigated the role of diabetes in the progression of malignancy. Subset analyses of Intergroup-0089 (INT-0089), a randomized trial comparing four fluorouracil-based adjuvant therapy regimens in patients with stage II and III colon cancer, supported several smaller studies that identified a higher rate of overall mortality in patients with colon cancer who also had diabetes. 70 – 72 Molecular rationale for this phenomenon may be linked to elevated serum levels of insulin, which accelerates proliferation of colorectal cell lines. 73 Providing clinical validation for this theory, a study of surgically resected patients with colorectal cancer reported that higher levels of C peptide and low levels of insulin-like growth factor binding protein-1 were associated with increased mortality. 74 Similar findings have been noted in patients with breast cancer, where elevated fasting insulin levels have been associated with an increased risk of distant recurrence and mortality in early-stage disease. 75 These studies have led to the development of clinical trials evaluating whether modulating the insulin axis would affect cancer outcomes. A provocative study assessing patients from the M. D. Anderson Cancer Registry identified a higher rate of pathologic complete response with neoadjuvant chemotherapy among diabetic patients taking metformin as compared with nondiabetic patients. 76 These and other supporting data have led to the development of a phase III intergroup trial (National Cancer Institute of Canada MA.32) examining the effect of metformin as adjuvant therapy for breast cancer. 77 The evolving understanding of the relationship between breast cancer and diabetes, ultimately leading to a potential therapeutic intervention, underscores the importance of understanding the link between and cancer. It is increasingly recognized that may also have a substantial impact on treatment tolerance. In the setting of advanced lung cancer, a randomized trial comparing vinorelbine alone or in combination with gemcitabine demonstrated a higher rate of treatment discontinuation among patients with a Charlson index (CCI) score of higher than 2. 78 Supporting this finding, data from a series of patients with breast cancer receiving dose-dense adjuvant chemotherapy identified an association between (defined as a CCI ≥ 1) and grade 3/4 toxicity. 79 Certain comorbidities may have an impact on tolerance for specific therapies as well. For instance, early observations with paclitaxel therapy suggested an increased risk for severe neuropathy in patients with a concomitant diagnosis of diabetes. 80 Similarly, the risk of cardiac toxicity with the HER2-directed monoclonal antibody trastuzumab is higher in patients with pre-existing hypertension. 81 , 82 Of note, an effort should be made to distinguish from treatment-related toxicity, as these may have different prognostic implications. As one example, the vascular endothelial growth factor targeting antibody bevacizumab has been noted to cause hypertension in clinical application across malignancies. 83 – 85 Subset analyses from pivotal trials of bevacizumab in lung and breast cancer have associated the development of hypertension with extended OS. 86 , 87 These results have led some investigators to question whether hypertension should be considered a dose-limiting toxicity. 88 59.

Whether cisplatin can be replaced safely by carboplatin in cisplatin-eligible patients, as we use to do in several other tumors (such as metastastic lung cancer or ovarian cancer), was addressed in one randomized phase III trial that was closed early due to slow accrual. Therefore we have no answer to that question with a high level of evidence. 3 randomized phase II studies showed lower CR and survival rates for the carboplatin combinations. In these studies older combinations like MVAC and MVECa, MVAC and Carbo MV and the newer doublets cis/gem vs carbo/ gem were used. and several smaller phase II studies with carboplatin/paclitaxel were disappointing with only about 9 months survival and RR below 50%. Carboplatin is an analog of cisplatin that appears to have a similar mechanism of actiong and spectrum of antineoplastic activity as cisplatin, and that may also have a more favorable toxicity profile. Carboplatin has been tested in the treatment of TCC fairly extensively. As a single agent, responses in 0-28% of patients have been reported.” A 45% response proportion has been reported for carboplatin in combination with methotrexate. When standard doses of carboplatin have been used in combination with methotrexate and vinblastine, 42-53% of patients will exhibit a response.”-I3 Waxman et al. added mitoxantrone Carboplatin for Transitional Cell GancerlSmall et al. 1779 to a carboplatin-based regimen, treating patients with methotrexate, 50 mg/mz; vinblastine, 3 mg/m'; mitoxantrone, 10 mg/m2, and a considerably lower carboplatin dose than that used in this trial (200 mg/m2) on Day 1, and methotrexate, 50 mg/m2 on Day 15 of a 28-day cycle. Although 64 patients were evaluable for response, only 27 patients were being treated for metastatic disease. An overall response proportion of 45% was rep~rted.'&quot;
Figure 1: Patients with only one reason for being unfit for cisplatin have a better OS than patients with both reasons (GFR<60 and WHO-PS2). The statistical difference between the 3 curves is significant. Figure 2: The post hoc analysis of OS by the Bajorin risk groups showed that, as the number of Bajorin risk factors increases, the OS decreases (highly significant). The data suggest that the Bajorin risk group is valid in this patient population. (The very small numbers in each risk group by treatment arm rule out a definitive conclusion in the treatment groups).
