Basal cell carcinoma (BCC) is the most common form of skin cancer in the United States. Due to the high frequency, BCC occurrences are not typically recorded, and annual rates of incidence can only be estimated. Current estimated rates are 2 million Americans affected annually, and this continues to rise. Exposure to radiation, from either sunlight or previous medical therapy, is a key player in BCC development. BCC is not as aggressive as other skin cancers because it is less likely to metastasize. However, surgery and radiation are prevalent treatment options, therefore disfigurement and limitation of function are significant considerations. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) outline an updated risk stratification and treatment options available for BCC.

Abstract Studies in mice and cross-sectional studies in humans support the premise that cellular senescence is a contributing mechanism to age-associated deficits in physical function. We tested the hypotheses that circulating proteins secreted by senescent cells are (i) associated with the incidence of major mobility disability (MMD), the development of persistent mobility disability (PMMD), and decrements in physical functioning in older adults, and (ii) influenced by physical activity (PA). Using samples and data obtained longitudinally from the Lifestyle Interventions in Elders Study clinical trial, we measured a panel of 27 proteins secreted by senescent cells. Among 1 377 women and men randomized to either a structured PA intervention or a healthy aging (HA) intervention, we observed significant associations between several senescence biomarkers, most distinctly vascular endothelial growth factor A (VEGFA), tumor necrosis factor receptor 1 (TNFR1), and matrix metallopeptidase 7 (MMP7), and the onset of both MMD and PMMD. Moreover, VEGFA, GDF15, osteopontin, and other senescence biomarkers were associated with reductions in short physical performance battery scores. The change in senescence biomarkers did not differ between PA and HA participants. In the whole cohort, higher levels of PA were associated with significantly greater reductions in 10 senescence-related proteins at 12 and/or 24 months. These data reinforce cellular senescence as a contributing mechanism of age-associated functional decline and the potential for PA to attenuate this hallmark of aging.

369 Background: Patient-reported outcomes (PROs) are a valuable component to understand treatment tolerability and toxicity. We have implemented an electronic system for monitoring PROs and quality of life (QOL) for patients enrolled in the I-SPY2 trial, a phase II trial evaluating the effect of novel neoadjuvant therapies for breast cancer. We associated patient demographic factors with symptoms, decline in physical function (PF), and tolerability to treatment. Methods: Study population for this analysis includes 259 enrolled patients receiving combinations of experimental immunotherapy and chemotherapy. Patients completed PRO-CTCAE/PROMIS/FACT surveys reflecting symptom severity, symptom frequency, tolerability of drug, and physical function at baseline through follow up (12 months). CTCAE 5.0 was collected weekly at these timepoints to assess adverse events (AE). Odds ratio and regularized multi-variate regression was used to evaluate early symptoms predictive of a clinically significant decline in PF from baseline to post-treatment follow-up. Results: Of 259 patients, 160 (58%) were White, 13 (5%) were Asian, 26 (10%) were African American (AA), and 25 (9.3%) were Hispanic. 25% of all patients had a clinically significant decline in PF between baseline and pre-surgery/follow-up. Symptom predictors of decline included high frequency of diarrhea and severity of joint pain. African American (AA) patients had higher severity of joint pain than White patients (OR = 14.9, P < 0.05). Within the first 12 weeks of treatment, AA patients and non-white (NW) patients were more likely to report severe vomiting than White patients (OR =13.22 and 12.72, P< 0.05 and P< 0.03 respectively). Overall, patients that reported lower tolerance to therapy had higher grade of AE. While patients with low-grade adverse events were less bothered by their side effects at follow-up, higher grade adverse events such as hypothyroidism impacted distress levels by more than double. Conclusions: Among I-SPY2 participants, when higher grade of symptoms is persistent through follow up, it impacts physical function and tolerability even after end of therapy. Our study can allow physicians to be more diligent in active and post treatment monitoring. Clinical trial information: NCT01042379 .

101 Background: In the US, minority patients are underrepresented in cancer clinical trials. This is due to multiple factors, including socioeconomic barriers, limited medical insurance coverage and restrictive clinical trial eligibility, e.g., ANC cutoff. For the latter, conservative ANC cutoff disadvantages Black patients. Two-in-three Black individuals have a Duffy-null phenotype, that is associated with lower ANC with 5% prevalence of ANC <1,500 cells/µl. To improve Black patient accrual to cancer clinical trials, lowering the ANC cutoff was proposed as a potential solution over a decade ago. Its implementation is not known. This study evaluates the ANC cutoff values as part of the eligibility criteria for cancer clinical trials. Methods: We accessed the Clinicaltrials.gov website on 5/25/2023 and obtained the ANC cutoff of cancer clinical trials conducted in the US. We included adult therapeutic trials in the phases of recruiting, not yet recruiting, enrolling by invitation, and active-not yet recruiting. Trials with drug interventions were selected. Those focusing on surgical, behavioral, nutritional and radiotherapeutic interventions were excluded. All ANC cutoff values were converted to “cells/µl” for analysis. Results: A total of 911 trials were evaluated, and 470 met the eligibility criteria. Of the 470 trials, 366 (78%) involved solid malignancies, and 104 (22%) involved hematologic malignancies. Hematologic trials have significantly lower ANC cutoffs compared to solid tumor trials with median ANC cutoff of 1,000 (range, 250-2000) vs. 1,500 (range 250-3,000); p=<0.001. In all, 323 trials (68.7%) required patients to have ANC >1,500, and 116 trials (24.6%), primarily hematologic, required patients to have ANC >1,000. For myeloma and prostate cancer, two cancers with higher incidence among Blacks, 12.9% and 86.4% of the trials require ANC >1,500, respectively. All genitourinary, breast, head & neck, sarcoma, lung, skin, and neuroendocrine tumor trials excluded patients with ANC <1,000. Conclusions: Most hematologic malignancy trials have a more liberal ANC cutoff allowing patients with ANC <1,500 to participate. However, solid tumor trials remain more conservative, with 4 in 5 trials requiring an ANC cutoff of >1,500. A strict ANC cutoff remains a barrier to minority accrual.[Table: see text]

There is a broad phenotypic spectrum of monogenic polycystic kidney diseases (PKDs). These disorders often involve cilia-related genes and lead to the development of fluid-filled cysts and eventual kidney function decline and failure. Preimplantation genetic testing for monogenic (PGT-M) disorders has moved into the clinical realm. It allows prospective parents to avoid passing on heritable diseases to their children, including monogenic PKD. The PGT-M process involves embryo generation through in vitro fertilization, with subsequent testing of embryos and selective transfer of those that do not harbor the specific disease-causing variant(s). There is a growing body of literature supporting the success of PGT-M for autosomal-dominant and autosomal-recessive PKD, although with important technical limitations in some cases. This technology can be applied to many other types of monogenic PKD and ciliopathies despite the lack of existing reports in the literature. PGT-M for monogenic PKD, like other forms of assisted reproductive technology, raises important ethical questions. When considering PGT-M for kidney diseases, as well as the potential to avoid disease in future generations, there are regulatory and ethical considerations. These include limited government regulation and unstandardized consent processes, potential technical errors, high cost and equity concerns, risks associated with pregnancy for mothers with kidney disease, and the impact on all involved in the process, including the children who were made possible with this technology.
