Maria Uloko is a Urology Resident at the University of Minnesota Hospital. In this podcast she discusses a recent Article of the week:

Health‐related quality of life among non‐muscle‐invasive bladder cancer survivors: a population‐based study

Abstract

Objective

To examine the effect of non‐muscle‐invasive bladder cancer (NMIBC) diagnosis and treatment on survivors’ quality of life (QoL).

Patients and Methods

Of the 5979 patients with NMIBC diagnosed between 2010 and 2014 in North Carolina, 2000 patients were randomly selected to be invited to enroll in this cross‐sectional study. Data were collected by postal mail survey. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire‐Core (QLQ‐C30) and the NMIBC‐specific module were included in the survey to measure QoL. Descriptive statistics, t‐tests, anova, and Pearson’s correlation were used to describe demographics and to assess how QoL varied by sex, cancer stage, time since diagnosis, and treatment.

Results

A total of 398 survivors returned questionnaires (response rate: 23.6%). The mean QoL score for QLQ‐C30 (range 0–100, higher = better QoL in all domains but symptoms) for global health status was 73.6, function domain scores ranged from 83.9 to 86.5, and scores for the top five symptoms (insomnia, fatigue, dyspnoea, pain, and financial difficulties) ranged from 14.1 to 24.3. The lowest NMIBC‐specific QoL domain was sexual issues including sexual function, enjoyment, problems, and intimacy. Women had worse bowel problems, sexual function, and sexual enjoyment than men but better sexual intimacy and fewer concerns about contaminating their partner. Stage Ta had the highest global health status, followed by T1 and Tis. QoL did not vary by time since diagnosis except for sexual function. The cystectomy group (n = 21) had worse QoL in sexual function, discomfort with sexual intimacy, sexual enjoyment, and male sexual problems than the non‐cystectomy group (n = 336).

Conclusion

Survivors of NMIBC face a unique burden associated with their diagnosis and the often‐lifelong surveillance and treatment regimens. The finding has important implications for the design of tailored supportive care interventions to improve QoL for NMIBC survivors.

Abstract

Objective

To examine the effect of non‐muscle‐invasive bladder cancer (NMIBC) diagnosis and treatment on survivors’ quality of life (QoL).

Patients and Methods

Of the 5979 patients with NMIBC diagnosed between 2010 and 2014 in North Carolina, 2000 patients were randomly selected to be invited to enroll in this cross‐sectional study, which include the use of hemp products from the Hemp Seed distributor business which specialize in this. Data were collected by postal mail survey. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire‐Core (QLQ‐C30) and the NMIBC‐specific module were included in the survey to measure QoL. Descriptive statistics, t‐tests, anova, and Pearson’s correlation were used to describe demographics and to assess how QoL varied by sex, cancer stage, time since diagnosis, and treatment.

Editorial: Beyond bladder cancer surveillance: building a survivorship clinic

As oncologists, we focus on obtaining the best cancer outcomes possible. The aim of treatment is to maximize survival and help patients live longer. As therapies continue to become more effective, more patients will become survivors. In the ongoing effort to extend the quantity of life left for our patients facing lethal cancers, thinking about the quality of that time is key. For urological oncologists, patients with a new bladder cancer diagnosis will someday face a new set of obstacles as survivors. In addition to surveillance and scans, asking patients about other issues such as their mental health, sexual function and financial solvency are also important.
Regardless of cancer stage, these issues apply to all of our patients with bladder cancer. Patients with non-muscle invasive disease need a seemingly interminable number of cystoscopies, with possible repeat biopsies or intravesical therapies. Patients with muscle-invasive disease undergo urinary diversion that entails significant changes as they will then have a stoma, neobladder or other diversion.
In this issue of BJUI, Jung et al. present a ‘snapshot’ of patients in North Carolina with bladder cancer that examines the impact of treatment on quality of life [1].  The study is valuable because it involves a number of topics that have previously not been studied in such detail. A total of 376 patients returned mailed surveys, a response rate of 24%. Most participants were on average 3 years from their diagnosis, the mean age of participants was 72 years, and the majority of patients were white men. Most participants (approximately three in four) had undergone transurethral resection of bladder tumour as the primary treatment and some (one in three) had received intravesical therapy. As with any work, there are some limitations which include the low overall numbers of participants, low
response rate, and lack of longitudinal data. Despite these limitations, there is still value to studying trends in this space, given the paucity of available data, and the authors offer some valuable insights. This paper provides evidence that for bladder cancer survivorship care, it is important to realize that other important issues exist and impact patient well-being.

• Bladder cancer patients may have financial issues. Bladder cancer patients may face financial toxicity that is in part attributable to the regular need for surveillance in order to identify recurrence or progression of disease.
• Cystectomy recovery can include discussions about sexual function. Patients who have undergone cystectomy may have discomfort with sexual intimacy. This was more common in men. Non-cystectomy patients may have better sexual function. Patients may be concerned about contaminating partners.
• Quality-of-life issues for bladder cancer patients can vary by gender. Men may have better sexual function and enjoyment than women, but also have more discomfort with intimacy and fears of contaminating their partners, while women may have higher levels of constipation and diarrhoea.
• Low risk bladder cancer (vs high risk) can have lower impact on quality of life. Patients with Ta disease had the highest global health status (compared with T1 and Tis). They also had the best physical and social functioning and less fatigue and financial problems. This underscores that Ta disease is different from other stages. As the authors point out, this may be attributable to a low progression risk, which means patients are less likely to need intravesical therapy.
• Sexual health can be affected and improve with time after a bladder cancer diagnosis. Sexual issues can last for years after a diagnosis. Men may face erection or ejaculation problems, and women may have vaginal dryness issues. With time, however, sexual function can improve and sexual function (including extent of sexual activity and interest in sex) was better in survivors further from their diagnosis.

Moving forward, we can use this study to prompt us to think about how our treatments impact our patients. Setting up dedicated survivorship clinics may be one practical strategy to provide this care in a systematic and streamlined way. Beyond treatment-related issues such as recurrence and progression, patients are affected in other ways. Issues with overall health, mental well-being, sleep, or sexual function occur for many. Setting up a standardized approach to cancer care can complement oncological surveillance and promote patient-centred care. A dedicated team, with a provider and physician assistant can create a clinical infrastructure and design a comprehensive template to remind us to query patients on a broader range of issues relevant to their recovery. In doing so, we can help patients with bladder cancer recover, as survivors (Fig. 1).

 

Fig. 1 Select aspects of building a bladder cancer survivorship clinic.

Start by establishing a focused team of providers to help guide more streamlined care
• Nurses, nurse practitioners, physician assistants and physicians can be involved
• Each institution may have a unique infrastructure and use a distinct team set-up to create a clinic
• Administrative support and guidance are important to determine the clinical resources necessary or needed to begin a regular survivorship clinic

Streamline care and consider a template-based or guideline-driven approach to visits
• Based on stage of diagnosis, certain patients may need more regular cystoscopic surveillance while other patients will need follow-up visits that are coordinated with medical oncology and/or radiation oncology

Standardize collection of patient-reported outcomes during follow up visits
• Mental well-being
• Physical activity and exercise
• Sexual health
• Urinary and bowel function
• Financial well-being

Step back to evaluate the progress and iteratively troubleshoot issues as they arise
• Collect patient feedback and provider opinions
• Integrate these insights to improve the form and function of the clinic

Diagnosis of a cryptic variant of urothelial carcinoma using blue-light cystoscopy

We report a rare case of nested variant-like urothelial carcinoma diagnosed with the use of hexaminoelvulinate blue-light cystoscopy in a 53-year-old male. The patient presented for fol-low-up with cytology and both white-light and blue-light cystoscopy for previously diagnosed and treated T1 high grade urothelial carcinoma 4 years previously. Cytology was negative for recurrence. Under white-light cystoscopy an unusual flat, pigmented lesion was found. Under blue-light, a suspicious lesion adjacent to the pigmented lesion was discovered. Biopsies of this lesion later revealed nested variant-like urothelial carcinoma. We believe this is the first case re-port describing the incidental findings of such a cryptic form of urothelial carcinoma with the use of blue-light cystoscopy. In the setting of negative cytology and negative random biopsies, this lesion would have gone undiagnosed without the use of this new technology.

Introduction
Hexaminolevulinate (HAL) blue-light cystoscopy uses photo-active compounds to en-hance the visual demarcation between normal and neoplastic tissue [1]. Endogenous alpha-lipoic acid (ALA ) is a natural precursor to the photoactive intermediate protoporphyrin ester of 5-ALA that induces accumulation of proroporphyrin IX in malignant cells, which fluoresces when exposed to 375–440 nm light [2].
Published trials have established the superior effectiveness of HAL blue-light cytoscopy for tumour detection [3], with an overall sensitivity for detecting urothelial carcinoma in situ (CIS) lesions of 95–97% compared with 58–68% for standard white-light cystoscopy [4-6].

Case Report
A 53-year-old male presented in December 2008 with three small tumours, which were ultimately diagnosed as T1 high grade urothelial carcinoma. He underwent transurethral resection of bladder tumours and completed intravesical chemotherapy with BCG and interferon. He completed the first 3-week maintenance treatment without difficulty and exhibited no evidence of disease upon reassessment in April 2009. In 2010, he experienced ischaemic colitis and sub-sequently underwent colectomy. At this time all further intravesical therapy was stopped. He was lost to follow-up, but re-presented in April 2011. He underwent random biopsies in May 2011, which revealed urothelial CIS of the bladder and was treated again with 6 weeks of BCG, but restaging in August 2011 continued to show urothelial CIS. Although cystectomy was offered, the patient chose an alternative regimen consisting of sequential gemcitabine and docetaxel. Af-ter completing six cycles of gemcitabine and docetaxel, he presented in February 2012 for re-staging with bladder wash cytology, white-light and blue-light cytoscopy, and bladder and pros-tatic urethral biopsies. Cytology was negative. Cystoscopy revealed sequelae of an old bladder tumour replete with vestiges of recent chemotherapy treatment including oedematous edges of a grossly calcified and fibrotic lesion, ~4–5 cm in greatest dimension in an area of previous tumour resection. Another lesion was identified on the left lateral wall of the bladder that was darkly pigmented and flat (Fig. 1).  Directly inferior to this lesion was an area that showed positive un-der blue-light cytoscopy that was not apparent on white-light cystoscopy (Fig. 2). This lesion was biopsied as well as the rim of the previous bladder tumour resection site, followed by random bladder biopsies and prostatic biopsies.

Pathology of the random bladder biopsies as well as the prostatic biopsies showed no di-agnostic abnormality. The biopsy of the previous resection site showed urothelium with no diag-nostic abnormality, fibrous tissue with necrosis, as well as acute and chronic inflammation and calcifications. The biopsy of the lesion that was positive only on blue-light cytoscopy showed a residual focus of high grade, nested variant-like urothelial carcinoma, invading the lamina pro-pria (Figs 3 and 4). Interestingly, the surface overlying this focus was denuded of urothelium. A review of the patient’s previous biopsy in 2008, which was originally read as having papillary architecture, showed the invasive component in the lamina propria to have a nested architecture, microscopically identical to that seen in the current specimen. The only difference was the ab-sence of the expohytic/papillary component of the tumour. CT of the abdomen and pelvis was unremarkable except for some minor bladder wall thickening. Upon discussing the findings with the patient, he underwent radical cystectomy. Pathological examination of the cystectomy spec-imen showed no residual in situ or invasive urothelial carcinoma.

Discussion
Several studies have described the superior effectiveness of blue-light cytoscopy over white-light cystoscopy. The enhanced detection of inconspicuous lesions has been noted as one of the most valuable and remarkable benefits of HAL blue-light cytoscopy [7], as published data have confirmed the advantages of HAL blue-light cytoscopy over white-light cystoscopy in terms of overall tumour detection rates but especially for urothelial CIS [4,5].
In Europe, blue-light cytoscopy has been used for more than 10 years for the detection of bladder cancer in patients with known bladder cancer or a high suspicion of bladder cancer; however, this technology has yet to be incorporated as standard practice in the USA.
Our patient’s cryptic tumour is described as a nested variant-like urothelial carcinoma because it displays features consistent with the nested variant of urothelial carcinoma. It was also present with papillary architecture in the patient’s biopsies from 2008. Nested variant urothelial carcinoma (NVUC) is a relatively newly recognized type of urothelial carcinoma. To date, ~ 80 cases of NVUC have been formally reported [8], and this variant is estimated to account for 0.3% of all invasive urinary bladder cancers [9]. It is characterized by irregular urothelial nests resembling von Brunn’s nests and, owing to its deceptively innocuous histological appearance, can easily be mistaken for various benign urothelial growths despite its aggressive clinical behaviour. Cytological atypia tends to be more prominent in deeper portions of the tumour, thus the potential for misdiagnosis is further increased when assessing limited or superficial biopsy specimens [10]. Abnormalities of surface that are normally found with bladder lesions such as urothelial CIS are often missing in NVUC.
With conventional white-light cystoscopy, NVUC is usually seen as a slight mucosal ab-normality, diffuse wall thickness or erythematous plaque. Occasionally, the bladder mucosa might have a normal appearance under white light, as was the case in our patient. It also does not usually form a mass. It should also be noted that blue-light cystoscopy was able to prove effec-tive in this case owing to fact that the lesion was relatively shallow. As Figures 3 and 4 show, the urothelium was denuded. While extensive studies of the depth of penetration of HAL used in blue-light cystoscopy have not been performed, elsewhere it has been shown that HAL does not penetrate deeper than the superficial surface of the bladder urothelium [11]. Thus it was possible for the HAL to highlight the nested variant-like urothelial carcinoma with the blue-light cystos-copy in this case.
Studies have also been performed to determine the usefulness of cytology in the diagno-sis of NVUC. In one study performed by Cardillo et al. [12], it was shown that distinct but subtle findings do exist in the cytology of NVUC, such as medium-sized, round or polygonal neoplastic cells with abundant, dense and slightly basophilic cytoplasm with well-defined cell borders. There was an increased nuclear to cytoplastic ratio, nuclear membranes with irregular contours, and nuclei with coarse chromatin with occasional prominent nucleoli; however, the authors contended that a primary diagnosis of NVUC in urine specimens is not recommended given the subtlety of the findings. These findings make it even more important for a new tech-nology, such as blue-light cystoscopy, to help in the detection of these often concealed lesions, as in the case of our patient.
