11. DISCUSSION
• Introduction
• Approach of MIBC
• Standard treatment
• Organ preservation protocol

• 4th MC cancer among men (7%)*
• 6th to 8th decade*

Chronic
irritation
*Cancer Statistics, 2016

13. • 8th mc cause of death among men *
• Responsible for about 4% of all cancer deaths among men *
• Pathologic predictors for recurrence and survival are tumor stage and nodal status
• 20-30% are MIBC *
* Cancer Statistics, 2016

14. MIBC
• 5 Yr-Survival rates after radical cystectomy*
• Death after appropriate local therapy is typically the result of systemic
disease
• Non–local regional relapses are reflective of the presence of
micrometastatic disease at the time of diagnosis

15. APPROACH
• Urine cytology
• RFT/LFT/S.E/ HMG
• CECT abd/pelvis
• Cystopanendoscopy (CPE)
• TURBT
• Chest radiography
• Bone scan

16. STANDARD TREATMENT
• Radical cystoprostatectomy with b/l pelvic lymphadenectomy
• Adequate pLND dissection- not defined
• Extended LND if CECT or frozen section shows paraortic spread
• Urinary diversion- incontinent or continent

17. PATTERN OF FAILURE AFTER CYSTECTOMY
Explanation
• Tumor cell spill in the pelvis during surgery
• Presence of tumor cells beyond the margins of surgical excision
• Dissemination of tumor cells to distant sites during surgical manipulation

18. • 10 randomised trials, 2688 patients
• All platinum-based
• overall survival increased from 45% to 50%
• Update in 2005, confirmed the same
• Other trials showed similar results*

19. Neoadjuvant chemotherapy
• Delayed surgery
• Interferred with pathological aspect
Adjuvant chemotherapy
• Is administered after accurate pathological staging,
• Treatment in patients at low risk for micrometastases is avoided
• No delay in definitive surgical treatment

20. • Included 6 trials
• All had platinum based chemotherapy
• Absolute improvement OS of 9% and DFS of 12% in 3 years
• Update in 2013 showed HR 0f 0.66
• This disease-free survival benefit was more apparent among
those with positive nodal involvement

21. PRE-OPERATIVE AND POST OPERATIVE RADIOTHERAPY
• Metanalyses * six randomized trials indicated no benefit to preoperative
irradiation collectively
• Adjuvant radiotherapy for bladder cancer has succeeded in decreasing the
local recurrence to a great extent in prospective randomized trials *
• Fear of GI complications resulted in infrequent use of PORT *
• Modern radiotherapy has the capability of increasing the effective dose to the
tumor target and decreasing the dose to the surrounding organs at risk
• Need to revisit PORT

22. LIMITATIONS OF RADICAL CYSTECTOMY
• Significant risk of perioperative morbidity and mortality  much improved now - 5.1-
8.1% 90 day mortality
• High morbidity – 90 day complication 28-64%
Acute gastrointestinal (29%), infection (25%), and wound-related complications (15%)
• High readmission rate
• Erectile dysfunction
• Urinary leakage/ incontinence
• Altered body image  orthotopic diversion
• Medical contraindications
• Poor performance status – most bladder cancer patients are old

24. EVOLUTION OF DEFINITIVE ROLE OF RADIOTHERAPY
Prompted more generalized application in muscle-invasive bladder cancer
Apparent success in some instances and the efficacy of salvage cystectomy in others
First provided to patients who were not considered suitable surgical candidates

25. BLADDER PRESERVATION THERAPY
• Radical Transurethral Resection
• Partial Cystectomy
• Radiotherapy monotherapy
• Chemoradiotherapy
• Trimodality approach (selective bladder preservation)

26. • No randomised prospective trial to compare radical cystectomy vs definitive
radiotherapy
• UK SPARE (Selective Bladder Preservation against Radical Excision) trial – phase I/II
trial
MIBC  neoadjuvant chemotherapy
trial closed due to poor accrual
RC CHEMORT

27. • 20,822 cases of bladder carcinoma
diagnosed in Ontario between 1982 and
1994

28. • Multicenter, phase 3 trial
• Randomly assigned 360 patients with MIBC to undergo
RT with or without synchronous chemotherapy
• 5 yr OS 48% in chemoRT and 36% in RT alone
• grade ¾ toxicity 8.3% vs. 15.7%, P=0.07

29. Patient matching

32. PATTERN OF FAILURE AFTER CHEMORT
• A significant proportion of patients will experience local failure- trial BC2001
• Most recurrences will occur within the first two to three years after cystectomy

36. • 468 patients five phase II studies and one phase III study
• Evaluated bladder preserving combined-modality therapy (CMT) for muscle-
invasive bladder cancer (MIBC), reserving cystectomy for salvage treatment
• The 5- and 10-year OS rates were 57% and 36%, respectively, and the 5- and
10-year DSS rates were 71% and 65%, respectively

37. 221 patients, T2-4Nx-0M0 bladder cancer, Treated on protocols 1986-2000, median follow up : 6.3 years
Urodynamic study, QOL questionnaire
• 78% had compliant bladders with normal capacity and flow parameters
• 85% had no urgency or occasional urgency
• 25% had occasional to moderate bowel control symptoms
• 50% of men had normal erectile function

38. • 93 patients were given self made questionnaire to analyse urinary, sexual, social functions
• QOL after cystectomy, marked by stoma presence, was reduced by a lack of sexual activity
and a worsened physical condition, but social and recreational life were little affected

39. 157 patients with Bladder Preservation who survived 2 to 13 years (Median follow-up - 5.2 years)
22% - Grade 1
10% - Grade 2
7% - Grade 3 (5.7% GU, 1.9% GI)

40. IMPACT OF NEOADJUVANT CHEMOTHERAPY ON ORGAN PRESERVATION IN
MUSCLE INVASIVE URINARY BLADDER CARCINOMA
Chinna Babu, Narendra Kumar, Santosh Kumar
• 20 patients of MIBC
• After Neoadjuvant chemotherapy
Partial Response(PR) >50% -18(90%) patients, received radical radiation
PR <50%- 2 patients(10%) underwent radical cystectomy
• Post RT- Complete response in all 18 patients
• With median follow up of 14 months--
2 patients (10%) had bladder recurrence-underwent salvage cystectomy
1 patient developed distant failure

41. Those involved in the management of muscle invasive bladder cancer should “take a
leaf from the book” on sarcoma and breast cancer management, where
multidisciplinary collaborative approach with knowledge and respect for the benefits
and shortcomings of individual treatment modalities has led to a standard of organ
preservation.

42. CONCLUSION
Traditional thinking
In most instances tumor will persist or recur after definitive RT  will
require salvage cystectomy
Radiation may compromise the suitability for appropriate surgery
But multiple studies have shown
Bladder preservation almost as good as radical cystectomy
Provides good bladder functioning
Not every case requires salvage cystectomy
Radiation does not hinder salvage cystectomy
For success of bladder preservation treatment
Better selection of patients and
Patient motivation for follow- up is must

cystectomy in terms of survival benefit and better
quality of life”
