Introduction

Hemorrhagic cystitis (HC) is an inflammation of the urinary bladder defined by signs of urinary bladder irritation and hematuria. The disease can be triggered by chemotherapeutic drugs exposure and radiation therapy for instance. It is well documented after exposure to cyclophosphamide [1,2,3] and oxoamide [4,5]. As a preventive measure after exposure to these drugs patients would receive Mesna to protect the bladder. It is thought that damage to the Glycosaminoglycan- (GAG) layer, which coats the uroepithelium and provides the initial barrier for physiological protection, may be the first step in its development [6].

The severity of HC can range from asymptomatic microhematuria to potentially life-threatening conditions such as the development of gross hematuria accompanied by clot formation, severe pain and occasionally uncontrollable bleeding, urinary tract obstruction and renal failure. In this latter setting, patients are extremely debilitated, require prolonged hospitalization and may eventually die [7]. The incidence rate of HC is predicted to rise substantially in the future as more aggressive treatments of cancer are implemented [9]. This acute complication is associated with significant rates of morbidity and mortality; treatment entails prolonged hospitalization and may require aggressive measures such as selective vesicle artery embolization or even cystectomy [8].

While dysuria, frequent voiding and urgency can be controlled with a symptomatic therapy, the challenging therapeutic targets in chemotherapy-induced HC are micturition symptoms and massive hematuria.

To date the following symptomatic treatment methods have been thoroughly evaluated [9]:

1. hyperhydration and continuous bladder irrigation
2. intravesical therapies, e.g. chondroitine sulphate, sodium hyaluronate, prostaglandin, formalin, and alum irrigation
3. systematic treatments, e.g. HBO, estrogen, sodium pentosanpolysulphate, recombinant factor VII or VIII, and aminocaproic acid

In our case report we outline the indications as well as procedural steps of our approach and compare the results with those of other therapies and troubleshooting recommendations. The report’s primary aim is to present the significant effect of an intravesical therapy with a specific product, Instillamed^®, a combination of chondroitine sulphate and sodium hyaluronate. To the best of our knowledge, the treatment as described has not yet been used in chemotherapy- induced HC.

Patient information

A 53-year old female patient presented with persistent dysuria, frequent voiding and nocturia. At the time the patient received adjuvant chemotherapy for her breast cancer (ypT2 (m) ypTis pyN1a (1/2) (sn) cMO G3 Stage IIB R1 VO PnO RO ER 90% PR 70% Her2neu +). Treatment included four cycles with epirubicin plus cyclophosphamide 90/600 mg/m² on a weekly basis, followed by 12 cycles of weekly Taxol^® and, every three weeks, Herceptin^® 600mg and Perjeta^®.

The patient presented with late-onset hemorrhagic cystitis after completing four cycles of chemotherapy, 10 weeks after finishing the last cycle. Therapy with D-Mannose had been tried without showing significant positive effects.

The patient had a daily fluid intake of 4–5 l, which relieved symptoms but caused a troublesome urgency-frequency syndrome.

Findings

Pelvic exam: External genitalia without erythema, exudate or discharge. The vestibulum is sensitive to pressure and pain. A hysterectomy was performed several years in the past. The vaginal vault is atrophic and no relevant prolapse is noted. The pelvic examination is unremarkable.

Dipstick test of the urine from intermittent catheter is positive for Erythrocytes, Leucocytes and Protein but negative for Nitrite. Bacteriological cultures were negative for bacterial growth.

During cystoscopy the bladder capacity was limited to 150 ml. Bladder mucosa was hyperemic with inflamed flushing areas. Ureteral orifice was normal in size, shape and position, ureteral jets were seen, Bladder neck was normal. Based on the patient’s history and the symptoms, our diagnosis was: Chemotherapy induced hemorrhagic cystitis Grade 1.

Method and Outcomes

We treated her with intravesical instillations of hyaluronic acid and chondroitin sulphate in order to substitute the GAG layer. The procedure was performed in an ambulant setting. Over a period of four months there were four instillations done once a week, followed by three more once a month.

At the end of this period objective changes could be seen:

1. An increase of bladder capacity from 150 ml to 250 ml
2. During a control cystoscopy bladder mucosa was normal, without any signs of irritation
3. Bladder washing cytology was normal

Discussion

Severe HC is a major complication in patients undergoing chemo- and/or radiotherapy. Despite the improvement of prophylactic measures, the incident rate for HC continues to be significant and remains associated with raised morbidity and mortality rates for cancer patients. With a tendency towards more aggressive treatment of cancer under review, the incidence of HC is likely to further increase in the foreseeable future [9]. Therefore the complications affiliated with HC should be considered an increasingly important clinical issue, because they are for the most part challenging conditions to treat.

Treatment is based on hyperhydration, platelet and blood-cell transfusions, bladder irrigation and pain management. Where these measures have failed to control HC, numerous therapeutic approaches can be applied but with poor success. Surgery is seen as the ultimate therapeutic approach for this complication, but the inherent morbidity of a major surgical procedure in an extremely debilitated patient makes this approach very problematic [10].

Today out-patient procederus and short-stay hospitalization are prioritized by patients, medical professionals as well as health insurers for reasons of costs and quality of life.

We report the successful treatment of a patient with severe HC: the ambulatory procedure consisted of a seven-week course of intravesical application of a GAG layer-substitution product. We noted that the instillation therapy significantly relieved bleeding, pain as well as dysuria, and was well tolerated by the patient.

Since it is a successful, safe and cost-effective procedure with no apparent side effects, we strongly suggest that intravesical instillation to restore the GAG layer should be considered a first-line treatment option in cases of severe HC. The question arises whether this could also prove to be an effective prophylactic option.

To the best of our knowledge, this treatment has not yet been used in chemotherapy induced HC.
