Using this guidance

The guidance set out here was reviewed extensively in the Autumn of 2024. There are no plans for any further reviews.

Medicine is constantly evolving and over time it is inevitable that the evidence base will change. Please use your own judgement and/or other sources of clinical guidance alongside the information set out here.

Please note this guidance is a recommendation and it should be used in the context of the overall care pathway and when all alternative interventions that may be available locally have been undertaken.

Summary

These recommendations target improvements in how care is delivered to patients with bladder cancer, aiming to reduce cancer recurrence, improve patient experience and reduce unwarranted variation by setting out best practice.

These recommendations outline how mitomycin C (MMC) is best administered posttransurethral resection of bladder tumour (TURBT). The need for prompt administration is guided by best evidence as well as a drive to deliver more TURBTs as day cases where this is clinically appropriate, improving patient experience and optimising the use of resources.

Mitomycin C (MMC), a chemotherapy agent, has been in use in urology practice for a decade and is recommended as part of the treatment of non-muscle invasive bladder cancer (NMIBC) to reduce recurrence. It is theorised that MMC kills cancer cells floating in the bladder, cells at the resection site and any missed tumours. This reduces recurrence and the need for further invasive and expensive interventions. Mitomycin C is instilled into the bladder after transurethral resection of bladder tumour (TURBT), a process which is termed ‘single post TURBT instillation of mitomycin C’ (SPI-MMC).

There is a wide variation in clinical practice relating to SPI-MMC. The Getting It Right First Time (GIRFT) urology programme identified variation in the proportion of patients being offered SPI-MMC, and when offered, variation in the timing and clinical setting in which it was administered. Exemplar units had functioning pathways that allowed installation of MMC in the operating theatre or recovery area, maximising the chance of a day case pathway for the patient. Where MMC was not given in theatre, patients were often reliant on administration on the ward and this could often lead to delays or, in some cases, missed doses. The most common reason cited for not being able to perform SPI-MMC in theatre related to local pharmacy guidelines on chemotherapy. Training was occasionally an issue, though this was usually easier to overcome.
Single dose MMC is used after first TURBT to reduce the likelihood of tumour recurrence.

Some patients having subsequent TURBTs are also prescribed SPI-MMC but those patients are outside the scope of this guidance. It is important that patients are consented for the administration of MMC prior to their first TURBT procedure and those with known intolerance or allergy to MMC do not receive it. At the time of the procedure, SPI-MMC should be administered where the operating surgeon identifies a bladder tumour that does not invade the muscle layer and there are no contraindications (perforation of the bladder, need for deep resection or need for irrigation due to ongoing gross haematuria). Histological examination of the tumour specimen is used to assess whether further intravesical chemotherapy may be required, but these subsequent procedures are not covered in this guideline.

Single dose MMC works best when delivered soon after TURBT. Best practice is for the operating surgeon / suitably qualified healthcare professional to administer the dose of chemotherapeutic agent in theatre as it reduces the risk of MMC being missed, minimises the need for patients to stay overnight and likely increases clinical efficacy. MMC is also administered in other locations including the recovery unit and the inpatient ward. In the ‘non-theatre’ setting, any appropriately trained medical practitioner can administer single dose MMC; in practice, this is normally a urology nurse specialist or a ward nurse with urology experience.

Recommendation

Scope

This recommendation applies to all patients undergoing their initial TURBT for a new nonmuscle invasive bladder cancer, who meet the clinical criteria for single dose mitomycin C administration as outlined in NICE guideline NG23.

It excludes patients with contraindications, such as allergies/intolerance to mitomycin C, bladder perforation/deep resection or significant post-operative bleeding.

Recommendations

  1. Single dose mitomycin C should be administered within the theatre or theatre recovery setting for all eligible patients following TURBT.
  2. Where this is not possible, single dose mitomycin C should be administered within 6 hours of the TURBT procedure being completed
  3. Mitomycin C should only be administered by appropriately trained practitioners.
  4. The use of closed systems (e.g. Mito-In or similar) is preferable for the delivery of mitomycin C.

These recommendations are in line with the GIRFT best practice day case TURBT pathway.

Rationale for recommendation

The panel considered the evidence supporting the use of intra-vesical chemotherapy, including MMC, in reducing the recurrence of NMIBC after TURBT. The panel discussed the findings of three systematic reviews relevant to the clinical question that provided data on recurrence rates and adverse effects. The key conclusions considered by the panel are summarised in table below.

A single instillation did not reduce recurrences in patients with a prior recurrence rate of more than one recurrence per year or in patients with an European Organization for Research and Treatment of Cancer (EORTC) recurrence score ≥5.

The number needed to treat to prevent one early recurrence was 9 (95% CI, 6-17 patients).No documented serious adverse events in any study (9 studies)

 

Regarding the timing of MMC instillation the panel considered the recommendations from international guidelines. Recently updated guidance from the European Association of Urology states:

‘Prevention of tumour cell implantation should be initiated within the first few hours after TURB. After that, tumour cells are firmly implanted and are covered by the extracellular matrix’.

‘To maximise the efficacy of SI, one should devise flexible practices that allow the instillation to be given as soon as possible after TURB, preferably within the first two hours in the recovery room or even in the operating theatre.’

Similarly, guidelines from the American Urological Association/Society of Urologic Oncology state:

‘In a patient with suspected or known low- or intermediate-risk bladder cancer, a clinician should consider administration of a single postoperative instillation of intravesical chemotherapy (e.g. gemcitabine, mitomycin C) within 24 hours of TURBT. In a patient with a suspected perforation or extensive resection, a clinician should not use postoperative intravesical chemotherapy.’

Scotland’s Quality Performance Indicators Programme also recommends administration within 24 hours following the initial TURBT (Scotland’s Quality Performance Indicators Programme). This aligns with NICE guidance NG2 which says:

‘Offer people with suspected bladder cancer a single dose of intravesical mitomycin C given at the same time as the first TURBT.’

As well as NICE quality standards for bladder cancer [QS106] which states:

‘Adults with suspected bladder cancer are offered a single dose of intravesical mitomycin C, given at the same time as the first transurethral resection of bladder tumour (TURBT).’

The panel discussed the differences between recommendations, especially the EUA guidelines, which advise MMC is delivered ‘within the first few hours after TURBT’ (as opposed to within 24 hours). The panel noted that most clinical trials evaluating MMC used a 24-hour limit as this was more pragmatic in terms of trial design. However, the panel discussed how the EUA guidelines reflect a belief among the urological community that early delivery is preferable as tumour cells become firmly implanted and covered by the extracellular matrix in the first few hours after TURBT.

The panel also considered qualitative feedback from GIRFT site visits (one panel member was the GIRFT urology lead) and its relevance to when and where MMC is delivered. Not administering MMC in theatre or recovery was identified as important driver of missed chemotherapy doses following TURBT by GIRFT. It was also flagged as a key contributor to delayed discharge and unnecessary overnight admissions. Units with optimal practice were discussed, including how barriers limiting the use of chemotherapy in theatre were overcome.

Taking the clinical and operational evidence together, the panel considered there was a clear rationale for delivering MMC as soon as possible after TURBT and that exemplar units had demonstrated that this was feasible. The panel was therefore of the opinion that that MMC be delivered in theatre or recovery, or within a 6-hour period of completing TURBT where this was not possible.

Evidence demonstrating the cost effectiveness of immediate (within 24 hours) vs delayed (within 2 weeks) MMC instillation was noted by the panel10 with one study demonstrating a mean saving of 1,350 euros per patient over a 3-year period. The panel agreed that further cost savings were achievable by maximising the day case rate, and that this would also help to improve patient experience (where wasn’t another clinical reason for admission).

This was felt to further justify the recommendation that MMC should be administered as soon as possible after TURBT, rather than simply within 24 hours.

Patient information

A transurethral resection of bladder tumour (TURBT) is the usual treatment for bladder cancer when it is diagnosed early. A thin tube called a cystoscope is inserted through your urethra (the tube through which you urinate) into the bladder. The cystoscope is used by your doctor to locate and remove cancerous tumours from your bladder.

Cancerous tumours can sometimes recur. To reduce the chance of tumours coming back, the chemotherapy drug mitomycin C can be administered directly into the bladder as part of the TURBT procedure. These drugs kill tumour cells effectively because they are targeted at the site of the cancer.

Mitomycin C should be administered as close to the TURBT as possible to maximise benefit. Evidence shows that patients who receive chemotherapy into the bladder immediately after a TURBT have an estimated 12-14% less chance of bladder cancer recurrence at five years.

Mitomycin C is not associated with the same adverse effects of conventional chemotherapy, such as hair loss or nausea. Occasional side effects (seen in 1-10% of patients) include mild skin in reactions and the temporary sensation of needing to pee more frequently.

This guidance aligns with the European Association of Urology and American Urological Association / Society of Urologic Oncology recommendations that mitomycin-C is routinely administered within 6 hours of a patient undergoing their first TURBT procedure, where the clinical criteria is met and in the appropriate relevant setting. By doing this within 6
hours after surgery it can maximise the clinical benefits of mitomycin-C and minimise the chance that a patient must stay unnecessarily in hospital when there are no other reasons for doing so.
