Although intravesical BCG remains the gold standard, the use of chemohyperthermia (CHT) as an alternative treatment is expanding all over the world. This study looks to compare the efficacy, safety, and tolerability of intravesical CHT with MMC vs BCG for intermediate and high risk NMIBC. METHODS: Between 2019 and 2021, 140 consenting NMIBC patients were randomised in a single centre study for 1-yr CHT (six weekly treatments and monthly maintenance treatments till 1 year) and 1-yr BCG immunotherapy (six weekly treatments and three weekly maintenance treatments at months 3, 6, and 12). Patients and physicians giving the interventions were aware of assignment and set protocols. Follow up was done by 3 monthly cystoscopy and urine cytology. Adverse effects were graded by using the Modified Clavien Dindo Classification. RESULTS: The 12 month Recurrence Free Survival (RFS) was 97.10% in the CHT group compared with 94.30% in the BCG group (p = 0.53). No progression in the NMIBC was seen in the CHT group whereas progression rate was 1.7% in the BCG group. Regarding the side-effects, during the induction phase initially the side effects were more in the BCG group, but with the progression of the induction cycles the side effects of the CHT group increased, with the most common side effects being LUTS, UTI, Fever and Bladder spasms. Side effects during the maintenance phase were comparable between the CHT and BCG groups. All the side effects were classified as either grade 1 or grade 2 based on the Modified Clavien Dindo Classification. A concern of the study is that the follow up period was short and thus the study is underpowered. Furthermore, blinding of treatment for patients and physicians was impossible; this may have resulted in unavoidable bias. CONCLUSIONS: CHT is a safe and effective treatment option in patients with intermediate- and high-risk NMIBC. A higher 12 month RFS in the CHT group was seen along with a comparable side effect profile. Based on the results above, CHT is an alternative option to intravesical BCG therapy as adjuvant treatment for intermediate and high-risk NMIBC.
