6 IS SURVIVAL BETTER AFTER SURGERY?

7 Survival from UK Registry data 453 UK pts, Ratio RT:cystectomy 3:1 10 year survival RT 22% Surgery 24% Munro NP, Sundaram SK, Weston PM, et al. A 10-year retrospective review of a nonrandomized cohort of 458 patients undergoing radical radiotherapy or cystectomy in Yorkshire, UK. Int J Radiat Oncol Biol Phys 2010;77:

8 Canadian Registry Data Bladder Cancer Variations in the use of total cystectomy and in the use of pelvic RT among the regions of Ontario were not associated with variations in survival. Survival was correlated with tumour related parameters Hayter CR, Paszat LF, Groome PA, et al: The management and outcome of bladder carcinoma in Ontario, Cancer 89: , 2000

9 WHAT CAN WE LEARN FROM OTHER CANCERS?

10 Anal cancer Primary therapy was surgery up until mid- 1980s Various chemo-rt regimens showed high activity with range of agents including 5FU, MMC, cisplatinum during 1970s surgery as the primary therapeutic modality has been abandoned.

11 CAN WE SALVAGE LOCAL FAILURES?

15 Are complication rates higher with salvage cystectomy? This large series from a high-volume centre demonstrates no difference in perioperative mortality in primary or postradiation salvage radical cystectomy. Similarly, there was no significant difference in the incidence of most of the surgical or medical complications..

16 Age at diagnosis Median age in BC2001 and BCON Median age in USC series Median age in BA06 & SWOG 8710 Male cases Female cases

17 Choice of treatment Surgery and radiotherapy data relate to different segments of the population Hence age/fitness is important factor in treatment decisions

18 CHEMORADIATION VS RADIOTHERAPY ALONE

34 Presence of residual mass, extent of resection and tumour size are related Stage Logrank test p= 0.11 T2 T Months Size of tumour Logrank test p=0.001 <30mm >=30mm Unknown Months Extent of tumour resection Logrank test p= 0.04 Biopsy/Not resected Complete resection Incomplete resection Months Residual mass post resection Logrank test p=0.005 No Yes Months The presence of residual mass was highly correlated with extent of resection 96% complete resections without residual mass 66% incomplete resections with residual mass

35 TURBT and residual mass Residual mass = high stage High stage = poor prognosis Therefore does not follow that RT only for patients with no mass post TURBT as these patients will do badly with surgery Also does not follow that TURBT actually needed

36 Should we change the diagnostic pathway?

37 What if breast cancer specialists behaved like urologists? Breast cancer would be diagnosed by 6 random needle cores in each breast Initial treatment would use a hot wire to scrape the middle of the tumour out, leaving the invasive bits round the edge to grow for several weeks while staging proceeds

38 What is the point of TURBT? Diagnosis Staging Treatment Palliation of symptoms from bladder

39 Non-muscle invasive bladder cancer 80% of total TURBT Diagnosis Staging Treatment Palliation of symptoms from bladder

40 Invasive bladder cancer TURBT Diagnosis Staging Treatment Palliation of symptoms from bladder - incomplete No - delayed Possibly If we could diagnose and stage a different way, treatment would be faster

41 TURBT in MIBC 5% overt bladder perforation rate 50% occult bladder perforation Large increase in circulating tumour cells Around 20% of pts have T2-4NxM0 disease but half of these get metastasis Could TURBT be actually spreading the cancer?

43 Ideal new pathway NMIBC Identify on imaging and biopsy/cytology Fast track to TURBT and subsequent therapy MIBC Stage with biopsy and MRI Fast track to definitive therapy TURBT only if urgently needed for symptoms e.g. intractable bleeding Problem: need to separate NMIBC from MIBC

51 BladderPath feasibility early impressions MRI protocol works well to distinguish T1 from T2 and above Team happy to make treatment decisions without full TURBT Post therapy MRI can be used for treatment assessment The trial is ongoing

54 CAN WE SELECT PATIENTS FOR BLADDER PRESERVATION?

55 Patients unsuitable for surgery Elderly Severe cardiovascular or chest problems Obese Diabetes Patients reluctant or unable to cope with stoma etc

56 Patients unsuitable for (chemo)rt Poor bladder function Highly symptomatic bladders Extensive CIS Prior pelvic RT Inflammatory bowel disease Certain genetic disorders

57 Conclusions No convincing evidence surgery superior to primary bladder preservation with salvage surgery Synchronous chemo-radiation is safe and improves pelvic control and is complementary to neoadjuvant treatment Patient reported outcomes and long term follow up confirm the benefits reported in BC2001
