RESUMEN

BACKGROUND: Survival following melanoma and chronic lymphocytic leukemia (CLL) have both been individually associated with previous history of non-melanoma skin cancers (specifically keratinocyte carcinomas [KC]). Furthermore, melanoma and CLL have been reported to occur within the same patients. The survival experience of patients with both cancers is understudied, and the role of history of KC is unknown. Additional research is needed to tease apart the independent associations between KC and CLL survival, KC and melanoma survival, and the co-occurrence of all three cancers. METHODS: A retrospective cohort study was conducted among patients who were diagnosed with melanoma and/or CLL at a comprehensive cancer center between 2008 and 2020. Multivariable Cox regression models were used to examine the association between history of KC and survival following melanoma and/or CLL with careful consideration of calendar year of diagnosis, treatment regimens and other risk factors. A nested case-control study comparing patients with both CLL and melanoma to those with only CLL or only melanoma was conducted to compare blood parameters across the three groups. RESULTS: A time-dependent association was observed between history of KC and favorable melanoma survival within 4 years following diagnosis and poorer survival post 7 years after melanoma diagnosis. History of KC was not significantly associated with survival following the diagnosis of CLL, after adjustment for clinical factors including historical/concurrent melanoma. Patients with co-occurring melanoma and CLL tended to be diagnosed with melanoma first and had elevated blood parameters including white blood cell and lymphocyte counts as compared with patients who were diagnosed with only melanoma. CONCLUSIONS: History of KC was an independent predictor of survival following melanoma but not of CLL. Additional studies are needed to determine if blood parameters obtained at the time of melanoma diagnosis could be used as a cost-effective way to identify those at high risk of asymptomatic CLL for the promotion of earlier CLL diagnosis.

RESUMEN

PURPOSE: Chimeric antigen receptor T-cell (CAR T) therapy is capable of eliciting durable responses in patients with relapsed/refractory (R/R) lymphomas. However, most treated patients relapse. Patterns of failure after CAR T have not been previously characterized, and may provide insights into the mechanisms of resistance guiding future treatment strategies. METHODS AND MATERIALS: This is a retrospective analysis of patients with R/R large B-cell lymphoma who were treated with anti-CD19 CAR T at a National Cancer Institute-designated Comprehensive Cancer Center between 2015 and 2019. Pre- and posttreatment positron emission/computed tomography scans were analyzed to assess the progression of existing (local failures) versus new, nonoverlapping lesions (de novo failures) and identify lesions at a high risk for progression. RESULTS: A total of 469 pretreatment lesions in 63 patients were identified. At a median follow-up of 12.6 months, 36 patients (57%) recurred. Most (n = 31; 86%) had a component of local failure, and 13 patients (36%) exhibited strictly local failures. Even when progressing, 84% of recurrent patients continued to have a subset of pretreatment lesions maintain positron emission/computed tomography resolution. Lesions at a high risk for local failure included those with a diameter ≥5 cm (odds ratio [OR], 2.34; 95% confidence interval [CI], 1.55-3.55; P < .001), maximum standardized uptake value ≥10 (OR, 2.08; 95% CI, 1.38-3.12; P < .001), or those that were extranodal (OR, 1.49; 95% CI, 1.10-2.04; P = .01). In the 69 patients eligible for survival analysis, those with any lesion ≥5 cm (n = 46; 67%) experienced inferior progression-free survival (hazard ratio, 2.41; 95% CI, 1.15-5.04; P = .02) and overall survival (hazard ratio, 3.36; 95% CI, 1.17-9.96; P = .02). CONCLUSIONS: Most patients who recur after CAR T experience a component of local progression. Furthermore, lesions with high-risk features, particularly large size, were associated with inferior treatment efficacy and patient survival. Taken together, these observations suggest that lesion-specific resistance may contribute to CAR T treatment failure. Locally directed therapies to high-risk lesions, such as radiation therapy, may be a viable strategy to prevent CAR T failures in select patients.

RESUMEN

Meteorological and even human-made disasters are increasing every year in frequency and magnitude. The passage of a disaster affects a society without distinction, but groups with social vulnerability (low socioeconomic status, chronic medical, or psychological conditions, limited access to resources) face the most significant impact. As a result, psychological and behavioral symptoms (eg, depression and anxiety) can ensue, making the immediate response of mental health services crucial. Secondary data from a database of a temporary healthcare unit were analyzed. A total of 54 records were reviewed to collect information; univariate and bivariate analyses were done. The purpose of this article is to present our experience regarding the incorporation of a mental health services model, with its respective benefits and challenges, into a temporary healthcare unit, after Hurricane Maria in 2017.
