RESUMO
(1) Background: Intravesical mitomycin-C (MMC) combined with hyperthermia is increasingly used in non-muscle invasive bladder cancer (NMIBC), especially in the context of a relative BCG shortage. We aim to determine real-world data on the long-term treatment outcomes of adjunct hyperthermic intravesical chemotherapy (HIVEC) with MMC and a COMBAT® bladder recirculation system (BRS); (2) Methods: A prospective observational trial was performed on patients with NMIBC treated with HIVEC using BRS in nine academic institutions in Spain between 2012-2020 (HIVEC-E). Treatment effectiveness (recurrence, progression and overall mortality) was evaluated in patients treated with HIVEC MMC 40mg in the adjuvant setting, with baseline data and a clinical follow-up, that comprise the Full Analysis Set (FAS). Safety, according to the number and severity of adverse effects (AEs), was evaluated in the safety (SAF) population, composed by patients with at least one adjunct HIVEC MMC instillation; (3) Results: The FAS population (n = 502) received a median number of 8.78 ± 3.28 (range 1-20) HIVEC MMC instillations. The median follow-up duration was 24.5 ± 16.5 (range 1-81) months. Its distribution, based on EAU risk stratification, was 297 (59.2%) for intermediate and 205 (40.8%) for high-risk. The figures for five-year recurrence-free and progression-free survival were 50.37% (53.3% for intermediate and 47.14% for high-risk) and 89.83% (94.02% for intermediate and 84.23% for high-risk), respectively. A multivariate analysis identified recurrent tumors (HR 1.83), the duration of adjuvant HIVEC therapy <4 months (HR 1.72) and that high-risk group (HR 1.47) were at an increased risk of recurrence. Independent factors of progression were high-risk (HR 3.89), recurrent tumors (HR 3.32) and the induction of HIVEC therapy without maintenance (HR 2.37). The overall survival was determined by patient age at diagnosis (HR 3.36) and the treatment duration (HR 1.82). The SAF population (n = 592) revealed 406 (68.58%) patients without AEs and 186 (31.42%) with at least one AE: 170 (28.72%) of grade 1-2 and 16 (2.7%) of grade 3-4. The most frequent AEs were dysuria (10%), pain (7.1%), urgency (5.7%), skin rash (4.9%), spasms (3.7%) and hematuria (3.6%); (4) Conclusions: HIVEC using BRS is efficacious and well tolerated. A longer treatment duration, its use in naïve patients and the intermediate-risk disease are independent determinants of success. Furthermore, a monthly maintenance of adjunct MMC HIVEC diminishes the progression rate of NMIBC.
RESUMO
La tetraplejia se define como una parálisis motora y sensitiva que afecta a brazos, piernas y tronco causada por un daño o lesión en la medula espinal, suponiendo un grave problema desde los puntos de vista psicosocial, económico y físico. Este relato biográfico ilustra precisamente el proceso de adaptación y afrontamiento de Jesús, un hombre que con dieciocho años sufrió un accidente de tráfico que le provocó esta grave discapacidad física, que le ha llevado a vivir en silla de ruedas. El informante relata el antes y el después de aquel trágico suceso que marcaría su vida para siempre (AU)
Quadriplegia is defined as a sensory and motor paralysis which affects to the arms, legs and trunk, and caused by damage or injury in the spinal cord. Quadriplegia assumes a serious problem from the psychological, economical and physical points of view. This biographical story illustrates precisely the process of adaptation and coping of Jesus, a man who -when he was eighteen- suffered a traffic accident that caused this severe physical disability, which has led him to live in a wheelchair. The protagonist explains the before and after of that tragic event which would bring about his life forever (AU)
