Prevalence of immune-related adverse events and anti-tumor efficacy in advanced/metastatic urothelial carcinoma following immune-checkpoint inhibitor treatment.

PURPOSE: We evaluated the prevalence of immune-related adverse events and anti-tumor efficacy in advanced/metastatic urothelial carcinoma following immune-checkpoint inhibitors (ICIs) treatment. METHODS: We conducted a multicenter retrospective study of patients with advanced/metastatic urothelial carcinoma treated with ICIs in four Spanish institutions. irAEs were classified using Common Terminology Criteria for Adverse Event (CTCAE) v.5.0 guidelines. The primary endpoint was overall survival (OS). Other endpoints were overall response rate (ORR) and progression-free survival (PFS). irAEs were evaluated as a time-dependent covariate to avoid immortal time bias. RESULTS: A total of 114 patients were treated with ICIs between May 2013 and May 2019, 105 (92%) of whom received ICIs as monotherapy. irAEs of any grade were experienced in 56 (49%) patients and 21 (18%) patients had grade ≥ 3 toxicity. The most frequent irAEs were gastrointestinal and dermatological toxicities, reported in 25 (22%) and 20 (17%) patients, respectively. Patients with grade 1-2 irAEs had significantly longer OS compared to those without grade 1-2 irAEs (median 18.2 vs. 8.7 months, HR = 0.61 [95% CI 0.39-0.95], p = 0.03). No association with efficacy was observed for patients with grade ≥ 3 irAEs. No difference in PFS was observed after adjusting for the immortal time bias. ORR was higher in patients who developed irAEs (48% vs 17%, p < 0.001). CONCLUSIONS: Our findings suggest that development of irAEs was associated with higher ORR, and patients who developed grade 1-2 irAEs had longer OS. Prospective studies are necessary to confirm our findings.

Teleoncology: A Solution for Everyone? A Single-Center Experience with Telemedicine during the Coronavirus Disease 2019 (COVID-19) Pandemic.

Since the beginning of the COVID-19 pandemic, the use of telehealth was rapidly implemented without previous evidence. The ONCOTELEMD study aimed to evaluate the opinion of patients attended via telemedicine during this period and to study factors that condition patient preferences on its use. Included patients had a confirmed cancer diagnosis and were contacted by telephone between 13 March and 30 April 2020, in the Medical Oncology Service of Hospital Parc Taulí, Sabadell. A 12-question survey was presented to them between 4 February and 19 April 2021. Statistical analysis was carried out using chi-square and multivariable logistic regression tests. Six hundred forty-six patients were included; 487 responded to the survey. The median age was 68 years (27-90), 55.2% were female. Most patients had a surveillance visit (65.3%) and were diagnosed with colorectal or breast cancer (43% and 26.5%, respectively); 91.8% of patients were satisfied, and 60% would accept the use of telemedicine beyond the pandemic. Patients aged more than 50 years (OR 0.40; 95% CI, 0.19-0.81; p = 0.01) and diagnosed with breast cancer (OR 0.45; 95% CI, 0.26-0.69; p < 0.001) were less predisposed to adopt telehealth in the future. Patients agreed to be informed via telehealth of scan or lab results (62% and 84%, respectively) but not of new oral or endovenous treatments (52% and 33.5%, respectively). Additionally, 75% of patients had a medium or low-null technologic ability, and 51.3% would only use the telephone or video call to contact health professionals. However, differences were found according to age groups (p < 0.0001). In total, patients surveyed were satisfied with telemedicine and believed telehealth could have a role following the COVID-19 pandemic. Moreover, our results remark on the importance of individualizing the use of telehealth, showing relevant data on patient preferences and digital literacy.

Reactivation of retinal toxoplasmosis despite evidence of immune response to highly active antiretroviral therapy.

We report a case of retinal toxoplasmosis that occurred in a patient with acquired immunodeficiency syndrome who had a previous diagnosis of cerebral toxoplasmosis, despite the patient having had a robust immune response to highly active antiretroviral therapy. Clinical decisions about whether to discontinue secondary prophylaxis for opportunistic infections continue to be challenging.
