These NCCN Guidelines for Distress Management discuss the identification and treatment of psychosocial problems in patients with cancer. All patients experience some level of distress associated with a cancer diagnosis and the effects of the disease and its treatment regardless of the stage of disease. Clinically significant levels of distress occur in a subset of patients, and identification and treatment of distress are of utmost importance. The NCCN Distress Management Panel meets at least annually to review comments from reviewers within their institutions, examine relevant new data from publications and abstracts, and reevaluate and update their recommendations. These NCCN Guidelines Insights describe updates to the NCCN Distress Thermometer (DT) and Problem List, and to the treatment algorithms for patients with trauma- and stressor-related disorders.

Abstract Uniparental disomy (UPD) is the inheritance of both chromosomal homologs from one parent. Depending on the chromosome involved and the parental origin, UPD may result in phenotypic abnormalities due to aberrant methylation patterns or unmasking recessive conditions in isodisomic regions. UPD primarily originates from somatic rescue of a single meiotically‐derived aneuploidy, most commonly a trisomy. Double UPD is exceedingly rare and triple UPD has not been previously described. Here, we report two unrelated clinical cases with UPD of multiple chromosomes; an 8‐month‐old male with maternal isodisomy of chromosome 7 and paternal isodisomy of chromosome 9, and a 4‐week‐old female with mixed paternal UPD for chromosomes 4, 10, and 14. These cases also demonstrate that although extremely rare, the detection of AOH on two or more chromosomes may warrant additional clinical and laboratory investigation such as methylation and STR marker analysis, especially when involving chromosomes known to be associated with imprinting disorders.

Background: Cotesting with the Papanicolaou (Pap) and human papillomavirus tests detects most precancerous and cancerous lesions and increases the sensitivity for detecting high-grade precancerous and invasive cervical cancers compared with human papillomavirus testing alone. Objective: To compare the use of the Papette brush (hereafter Papette) to the traditional spatula with endocervical brush (cytobrush) for cervical cancer screening. Design: Pragmatic observational study. Methods: Adult women aged 21–64 years who were eligible for a Papanicolaou test at a Midwest Community Internal Medicine practice underwent cervical cancer screening using the Papette or spatula with cytobrush from 18 August 2021 through 1 February 2022. Cluster sampling was used across the practice. Pathology reports were then analyzed to compare the number of satisfactory versus unsatisfactory results between the two collection techniques. Results: We collected results for 756 Pap tests. The test results were satisfactory with the Papette 93.8% of the time compared with 93.0% for the spatula with cytobrush. Conclusion: The Papette is not inferior to a spatula with cytobrush as a collection method for Pap tests.

Introduction Various clinical trials addressing large core acute ischemic stroke (AIS) are ongoing from multiple international groups. Future development of clinical guidelines depends on meta‐analyses of these trials calling for a degree of homogeneity of elements across the different studies. The aim of this common data element study was to provide an overview of the key features of pertinent large core infarct trials. Methods PubMed and ClinicalTrials.gov databases were screened for published and ongoing clinical trials assessing mechanical thrombectomy in patients with AIS with large core infarct. Nested Knowledge AutoLit living review platform was utilized to categorize primary and secondary outcomes as well as inclusion and exclusion criteria for patient selection in the clinical trials. Results The most reported data element was ASPECTS score, but with varied definitions of what compromises large core. Non‐utility‐weighted modified Rankin Score (mRS) was reported in 6/7 studies as the primary outcome, while the utility‐weighted mRS was the outcome of interest in the TESLA trial, all of them at the 3‐months mark, with only LASTE looking for mRS shift at the 6‐months mark. Secondary outcomes had more variations. Mortality is reported separately only in 4/7 trials, all at the 3‐month mark. Additionally, the TENSION trial reports the frequency of serious adverse events, including mortality, at the 1‐week and 12‐month mark. Conclusions In the published and the ongoing large core trials, there is a large degree of variability in the collected data elements. Differences in definition and timepoints renders reaching a unified standard difficult, which hinders high quality meta‐analyses and cohesive evidence‐driven synthesis.

Abstract Goals/Purpose Perioperative management of estradiol therapy varies considerably among plastic surgeons performing aesthetic surgeries. This study aimed to review available literature regarding perioperative management of estradiol therapy in aesthetic surgery patients, and the risk it poses for developing VTE in the perioperative period. Methods/Technique A literature search was performed using online databases to identify studies evaluating VTE in aesthetic surgery patients taking oral contraceptives (OCPs) or hormone replacement therapy (HRT), and transgender patients on feminizing hormone therapy undergoing non-flap feminization surgery (facial feminization and breast augmentation procedures). Reported outcomes were extracted from these studies and summarized. Results/Complications A systematic review of the literature yielded 225 studies. Five of these studies met inclusion criteria. One study that was excluded, referenced an article that met inclusion criteria, which was ultimately included in our review for a total of six studies, representing 3,635 patients. Conclusion Data regarding perioperative management of estrogen therapy is limited in the literature, and standardized guidelines for aesthetic surgery patients have not been elucidated. This has led to inconsistencies in how estrogen is managed for elective, cosmetic procedures. Further research is needed to determine standardized practice guidelines. In the meantime, case-by-case evaluation of surgical appropriateness should continue. Surgeons should also consider risk-mitigating strategies, such as a focus on patient education, more intentional patient questioning regarding estrogen-containing product use, a preoperative coagulability workup for patients with a personal or family history indicative of possible coagulopathy, and specialty-wide efforts to create an aesthetics database and evidence-based guidelines.

Abstract Introduction: The utilization of self reported chemotherapy treatment data is common in epidemiologic research but there is little understanding of its accuracy and limitations. Methods: The Mayo Clinic Breast Disease Registry (MCBDR) has over 9,600 participants enrolled within one year of a first breast cancer diagnosis. Participants receive annual follow up surveys through the mail to capture data on breast cancer treatments and outcomes. We compared nurse abstracted medical record chemotherapy data to self reported chemotherapy data from women diagnosed with stage 0 to 3 breast cancer that completed five consecutive annual follow up surveys. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) statistics were assessed for the report of broad chemotherapy receipt (yes, no, DK) within each yearly survey compared to the gold standard medical record data. To assess the accuracy of the self reported use of specific chemotherapy regimens, a sub cohort known as the “congruent sub cohort” was created for each survey year that included subjects that agreed with the nurse abstractors report of their broad chemotherapy usage. Sensitivity, specificity, PPV, NPV, and concordance statistics were calculated for the congruent sub cohorts followed by an assessment of the proportion of subjects providing correct responses for all chemotherapy regimens queried compared to those that had at least one discrepancy with the nurse abstracted data and the proportion of subjects with 0, 1, 2 and 3 or more discrepancies within each survey year. Results: For the 430 survey respondents, the average age was 59.5 years (SD 11.7) with a range of 29 to 94. The mean time between diagnosis and the year 1 follow up survey was 13.5 months, with an average of 61.2 months between diagnosis and the year 5 survey. The respondents were 97% white, 100% female, and 53.5% had a bachelor’s degree or higher. The self-reported receipt of chemotherapy had substantial agreement across all 5 follow up surveys with the nurse abstracted treatment data from the medical record with kappa values ranging from 0.70 (0.63 to 0.76) to 0.64 (0.57 to 0.71). For subjects in the congruent sub cohort (N=125, 120, 122, 121, and 121 subjects across the 5 survey years, respectively), self reported use of specific chemotherapy regimens were reported with an average concordance of 90% across the 5 annual surveys, however only 23% had perfect agreement with nurse abstracted data. The average number of discrepant responses provided by subjects was 1.2, with at least 12% of subjects reporting 3 or more erroneous responses for the specific chemotherapy regimens each survey year. Discussion: This study supports previous findings that self-reported chemotherapy usage may be utilized when resources are unavailable for medical record abstraction, but may have less utility when analyzing specific chemotherapy regimens.

Abstract Lung squamous cell carcinoma (LUSC) is a major histological subtype of lung cancer accounting for ~30% of all lung cancer diagnoses. LUSC patients suffer from poor therapeutic response, high relapse rate, and poor prognosis. A major reason for this bleak outcome is the lack of well characterized oncogenic drivers of LUSC. This has stalled the generation of relevant genetic pre-clinical mouse models amenable to studying LUSC tumorigenesis in vivo and developing targeted therapeutics to treat LUSC patients. Our group has identified concomitant 3q26 copy number gain (CNG) and TP53 loss as defining genetic alterations present in ~90% of LUSC tumors. Furthermore, we have identified three 3q26 oncogenes (PRKCI, ECT2 and SOX2) that genetically and biochemically collaborate to drive LUSC tumor formation. Coordinate overexpression of Prkci, Ect2 and Sox2, and loss of Trp53 in ex vivo cultures of lung basal stem cells (LBSCs; a potential cell of origin for LUSC) is both necessary and sufficient to transform these cells into orthotopic LUSC tumors in syngeneic mice. These findings indicate that 3q26 amplification and TP53 loss play a critical role in the initiation and progression of LUSC. Based on these data, we have developed the first autochthonous genetically engineered mouse model (GEMM) to study the role of 3q26 CNG in LUSC tumorigenesis in vivo. Our GEMM allows inducible overexpression of Prkci, Ect2, and Sox2 and knockout of Trp53 (PES/Trp53−/−) in lung tissue. Tumorigenesis will be initiated in PES/Trp53−/− mice using an established protocol to target transgene recombination to LBSCs in vivo. These mice will be assessed for tumor latency, survival, tumor burden, and metastatic potential. In related studies, we used bioinformatics analyses on primary LUSC tumors from the Cancer Genome Atlas’ database to identify 13 genes in addition to PRKCI, ECT2 and SOX2, whose expression is driven by 3q26 amplification. These genes were functionally characterized by assessing the effect of shRNA-mediated gene silencing on soft-agar growth of human H520 LUSC cells, a cell line that harbors 3q26 amplification. Our results revealed that knockdown of each of these genes independently resulted in a significant decrease in soft agar colony formation. We further assessed these genes through RT-qPCR mRNA expression profiling comparing PES/Trp53−/- transformed LBSCs to non-transformed LBSCs. These genes were significantly upregulated in PES/Trp53−/- transformed LBSCs, suggesting that they play important roles in LBSC transformation. Future work will further assess the molecular mechanisms by which these additional 3q26 genes contribute to LUSC cell transformation and assess the role of alternate cells of origin (Club and AT2) in 3q26-driven LUSC tumor formation using our PES/Trp53−/− GEMM.

Abstract Context Chronic hypoparathyroidism is conventionally treated with oral calcium and active vitamin D to reach and maintain targeted serum calcium and phosphorus levels, but some patients remain inadequately controlled. Objective To assess long-term safety and efficacy of recombinant human parathyroid hormone (1-84) (rhPTH(1-84)) treatment. Methods This was an open-label extension study at 12 US centers. Adults (n = 49) with chronic hypoparathyroidism were included. The intervention was rhPTH(1-84) for 6 years. The main outcome measures were safety, biochemical measures, oral supplement doses, bone indices. Results Thirty-eight patients (77.6%) completed the study. Throughout 72 months, mean albumin-adjusted serum calcium was within 2.00 to 2.25 mmol/L (8.0-9.0 mg/dL). At baseline, 65% of patients with measurements (n = 24/37) were hypercalciuric; of these, 54% (n = 13/24) were normocalciuric at month 72. Mean serum phosphorus declined from 1.6 ± 0.19 mmol/L at baseline (n = 49) to 1.3 ± 0.20 mmol/L at month 72 (n = 36). Mean estimated glomerular filtration rate was stable. rhPTH(1-84)-related adverse events were reported in 51.0% of patients (n = 25/49); all but 1 event were mild/moderate in severity. Mean oral calcium supplementation reduced by 45% ± 113.6% and calcitriol by 74% ± 39.3%. Bone turnover markers declined by month 32 to a plateau above pretreatment values; only aminoterminal propeptide of type 1 collagen remained outside the reference range. Mean bone mineral density z score fell at one-third radius and was stable at other sites. Conclusion 6 years of rhPTH(1-84) treatment was associated with sustained improvements in biochemical parameters, a reduction in the percentage of patients with hypercalciuria, stable renal function, and decreased supplement requirements. rhPTH(1-84) was well tolerated; no new safety signals were identified.
