RESUMO

PURPOSE: To present an oral anesthesia protocol for in-office oculoplastic surgery and to compare safety outcomes and patient and physician experiences to ambulatory surgery center (ASC)-based surgery with intravenous sedation or general anesthesia. METHODS: A prospective study was performed on consecutive patients undergoing surgery at an oculofacial plastic surgery practice. Surgery was performed in an in-office setting using our standardized oral sedation protocol or at an ASC with intravenous sedation or general anesthesia. Preoperative and postoperative surveys were conducted by patients and physicians to compare surgical experience, safety, and efficacy of our oral sedation protocol for in-office surgery in the ASC setting. RESULTS: Two hundred and fifty-three patients (167 in-office and 86 at ASC) underwent surgery between March and November 2022. There was no significant difference in how patients or physicians rated their experience between the 2 locations. A significantly higher proportion of ASC patients would have rather had surgery in-office (34.9% vs. 19.2%; p = 0.006). A significantly higher number of physicians in the office setting would have rather performed surgery at the ASC than the reverse (12.7% vs. 2.3%, respectfully; p = 0.007). There were no safety complications reported in either setting. CONCLUSIONS: Within our patient cohort, the presented oral sedation protocol provided safe and effective anesthesia for in-office oculoplastic surgery that is comparable to an ASC.

RESUMO

In Canada, the conversation to enable access to therapeutic psychedelics is under way. With recent federal initiatives, Canadians can request access to psychedelic-assisted therapies (PATs) to alleviate enduring and intolerable psychological suffering (EIPS) associated with life-threatening conditions on a case-by-case basis. The resurgence of past research concerning the therapeutic potential of PATs, promising preliminary results from contemporary clinical trials, public and media interest and the recognition of traditional Indigenous use of psychedelics have facilitated a change in the popular narrative around these stigmatized substances. A lack of access to PATs for treating EIPS, especially at end of life, is a public policy problem worth addressing.

RESUMO

BACKGROUND/OBJECTIVES: The purpose of this study is to report cases of choroidal melanoma that developed extrascleral tumour recurrence after treatment with iodine-125 brachytherapy. SUBJECTS/METHODS: In this single-institution retrospective observational case series, all instances of biopsy-confirmed orbital melanoma after known intraocular melanoma were reviewed. Tumour characteristics, clinical course, time to recurrence, cytogenetics of initial tumour and recurrence, and presence of intraocular recurrence were documented. RESULTS: Five cases of orbital melanoma following treatment with plaque radiotherapy are described. Tumour staging was Ia (1), IIa (2), and IIb (2). The primary lesion in four of the five appeared to have undergone complete regression for an average of 2 years, with the orbital melanoma developing after this interval. Recurrence of the intraocular tumour was seen in conjunction with an extrascleral component in two cases. Four cases ultimately underwent enucleation or exenteration; three had evidence of direct extension of tumour through the sclera. Four cases in this series had molecular characteristics associated with high metastatic risk (three patients with monosomy 3, one with BAP1 mutation). CONCLUSIONS: High-risk tumour biology may predispose to late appearance of extrascleral melanoma despite optimal treatment and adequate control of the intraocular tumour. Extended follow-up with detailed orbital examination and imaging is recommended for this population.

RESUMO

(1) Background: Patients and survivors of head and neck cancer (HNC) are at a high risk of developing body image concerns. Despite the prevalence of body image concerns in patients with HNC, there is a lack of longitudinal research exploring the wide array of its associated determinants. The current longitudinal study examined the determinants and longitudinal course of body image dissatisfaction in patients with HNC. (2) Methods: Patients participated in Structured Clinical Interviews and self-administered questionnaires at four time-points: (T1) upon cancer diagnosis, (T2) at 3 months post-diagnosis, (T3) at 6 months post-diagnosis, and (T4) at 12 months post-diagnosis. They also underwent a disfigurement rating on an objective scale. (3) Results: Two hundred and twenty-four patients participated in our study. Fourteen percent to twenty-eight percent of patients reported at least moderate body image concerns across time points, with the lowest rates at baseline and the highest at 3 months (T1). It was found that patients more predisposed to developing higher levels of body image concerns presented physical markers (i.e., advanced cancer stage, lower physical functioning, higher disfigurement), psychosocial markers (i.e., higher depression, higher anxiety, and higher levels of coping with denial), and health disparities (i.e., younger age, female sex, French language, and marital status, with divorced and widowers most affected). (4) Conclusions: The findings of this study highlight the multifaceted nature of body image concerns in patients with HNC and its biopsychosocial determinants. Clinicians should pay specific attention to these biopsychosocial markers in their clinics to predict high levels of body image concerns and tailor communication/refer for support accordingly.

RESUMO

Objective: Head and neck cancer (HNC) treatments are known to significantly affect functionality and appearance, leading to an increased risk for body image disturbances. Yet, few longitudinal studies exist to examine body image in these patients. Based on a conceptual model, the current study aimed to determine, in patients newly diagnosed with HNC: (1) the prevalence, level, and course of body image concerns; (2) correlates of upon cancer diagnosis (pre-treatment) body image concerns; (3) predictors of immediate post-treatment body image concerns; and (4) association between body image concerns and levels of anxiety, depression, suicidal ideation, support (i.e., satisfaction with support from physician, social/family wellbeing, and unmet support needs), and alcohol and drug misuse. Methods: Two hundred and twenty-three (participation rate = 72%), newly diagnosed with a primary HNC were assessed using structured clinical interviews and psychometric measures at three, and 6 months after diagnosis. Primary outcome was 3-month, as it was most salient to body image disturbance. Multiple linear regression analyses were conducted on the potential body image predictors, based on the model. Results: Sixty-eight percent of patients with HNC (n = 148 of 218) presented some level of body image concerns. Body image concerns at baseline (i.e., upon cancer diagnosis, pre-treatment) and post-treatment were significantly related and significantly increased from pre- to post-treatment. Immediately post-treatment (i.e., at 3 month follow-up), 89% (n = 132 of 148) presented some level of body image concerns. Correlates of body image concerns in patients with HNC at baseline included: physical symptom burden, difficulties with communication and eating, coping with the cancer diagnosis using denial, suicidal ideation, and having had a past anxiety diagnosis. When controlling for sociodemographic and medical variables, body image concerns in patients with HNC in the immediate post-treatment were predicted by: baseline body image, physical symptom burden, and neuroticism. Conclusion: This longitudinal study helps identify patients more susceptible to experience body image disturbance following head and neck cancer. Clinicians ought to pay special attention to body image concerns upon cancer diagnosis, physical symptom burden, and neuroticism, and may want to target these factors in future preventive interventions.

RESUMO

BACKGROUND: The ability to identify genetic alterations in cancers is essential for precision medicine; however, surgical approaches to obtain brain tumor tissue are invasive. Profiling circulating tumor DNA (ctDNA) in liquid biopsies has emerged as a promising approach to avoid invasive procedures. Here, we systematically evaluated the feasibility of profiling pediatric brain tumors using ctDNA obtained from plasma, cerebrospinal fluid (CSF), and urine. METHODS: We prospectively collected 564 specimens (257 blood, 240 urine, and 67 CSF samples) from 258 patients across all histopathologies. We performed ultra-low-pass whole-genome sequencing (ULP-WGS) to assess copy number variations and estimate tumor fraction and developed a pediatric CNS tumor hybrid capture panel for deep sequencing of specific mutations and fusions. RESULTS: ULP-WGS detected copy number alterations in 9/46 (20%) CSF, 3/230 (1.3%) plasma, and 0/153 urine samples. Sequencing detected alterations in 3/10 (30%) CSF, 2/74 (2.7%) plasma, and 0/2 urine samples. The only positive results were in high-grade tumors. However, most samples had insufficient somatic mutations (median 1, range 0-39) discoverable by the sequencing panel to provide sufficient power to detect tumor fractions of greater than 0.1%. CONCLUSIONS: Children with brain tumors harbor very low levels of ctDNA in blood, CSF, and urine, with CSF having the most DNA detectable. Molecular profiling is feasible in a small subset of high-grade tumors. The level of clonal aberrations per genome is low in most of the tumors, posing a challenge for detection using whole-genome or even targeted sequencing methods. Substantial challenges therefore remain to genetically characterize pediatric brain tumors from liquid biopsies.

RESUMO

PURPOSE: To describe a novel surgical technique for implanting eyelid weights via a sutureless transconjunctival approach. In comparison to the traditional supratarsal crease approach, this technique does not involve any external incisions or suture placement. The procedure can reduce surgical time and complications associated with the traditional external approach. METHODS: This case series includes 13 patients who underwent eyelid weight placement via the transconjunctival approach for paralytic lagophthalmos secondary to facial nerve paralysis (12 patients had unilateral paralysis and 1 patient had bilateral) with a total of 14 eyelid weights placed. The procedures were performed at an outpatient office-based surgical center. All procedures were performed or supervised by the same surgeon. Patients were followed for an average 6-month postoperative period for postoperative complications. RESULTS: The sutureless transconjunctival approach to eyelid weight insertion was successful in achieving the desired functional and aesthetic outcomes. Patients undergoing this technique avoided the discomfort of postoperative suture removal. All patients achieved comparable outcomes postoperatively. There were no complications reported across the 13 patients throughout the 6-month postoperative period. CONCLUSIONS: This case series demonstrates that the transconjunctival approach for metal eyelid weight insertion is practical, relatively easy to perform, and associated with functional outcomes that are comparable to those achieved with the traditional approach, however, without external incision or placement of sutures.

RESUMO

PURPOSE: This perspective explores the term "Asian blepharoplasty" and its socioemotional meaning to some patients. METHODS: N/A. RESULTS: Words have power. The term "Asian blepharoplasty" makes some patients uncomfortable. To our knowledge, it is the only medical descriptor that uses race. CONCLUSIONS: The use of the term "Asian Blepharoplasty" may unwittingly make patients uncomfortable and pathologize Asian features. Therefore, we suggest replacing the term "Asian Blepharoplasty" with "Double Eyelid Surgery." For the subset of procedures which do not include the creation of an eyelid crease, "Blepharoplasty" is appropriate.

RESUMO

Isolated orbital periphlebitis in the context of nonspecific orbital inflammation is rare. This case series describes 3 patients with periphlebitis of the superior ophthalmic vein, 2 of which were confirmed with pathology. All 3 cases had a history of Graves hyperthyroidism. Superior ophthalmic vein periphlebitis is a rare form of orbital inflammation presenting with proptosis and motility restriction yet few inflammatory signs. It may be associated with autoimmune hyperthyroidism and represent a rare feature of thyroid eye disease, or perhaps could be an overlap syndrome between thyroid eye disease and nonspecific orbital inflammation. Treatment response is variable and may require a prolonged course of steroids or other immunosuppressive medications.

RESUMO

PURPOSE: Existing cell-free DNA (cfDNA) methods lack the sensitivity needed for detecting minimal residual disease (MRD) following therapy. We developed a test for tracking hundreds of patient-specific mutations to detect MRD with a 1,000-fold lower error rate than conventional sequencing. EXPERIMENTAL DESIGN: We compared the sensitivity of our approach to digital droplet PCR (ddPCR) in a dilution series, then retrospectively identified two cohorts of patients who had undergone prospective plasma sampling and clinical data collection: 16 patients with ER+/HER2- metastatic breast cancer (MBC) sampled within 6 months following metastatic diagnosis and 142 patients with stage 0 to III breast cancer who received curative-intent treatment with most sampled at surgery and 1 year postoperative. We performed whole-exome sequencing of tumors and designed individualized MRD tests, which we applied to serial cfDNA samples. RESULTS: Our approach was 100-fold more sensitive than ddPCR when tracking 488 mutations, but most patients had fewer identifiable tumor mutations to track in cfDNA (median = 57; range = 2-346). Clinical sensitivity was 81% (n = 13/16) in newly diagnosed MBC, 23% (n = 7/30) at postoperative and 19% (n = 6/32) at 1 year in early-stage disease, and highest in patients with the most tumor mutations available to track. MRD detection at 1 year was strongly associated with distant recurrence [HR = 20.8; 95% confidence interval, 7.3-58.9]. Median lead time from first positive sample to recurrence was 18.9 months (range = 3.4-39.2 months). CONCLUSIONS: Tracking large numbers of individualized tumor mutations in cfDNA can improve MRD detection, but its sensitivity is driven by the number of tumor mutations available to track.

RESUMO

PURPOSE: We designed a novel, manualized intervention called Emotion And Symptom-focused Engagement (EASE) for acute leukemia (AL) and report here on a phase II randomized controlled trial (RCT) to assess its feasibility and preliminary efficacy. METHODS: Patients were recruited within 1 month of hospital admission and randomized to EASE plus usual care (UC) or UC alone. EASE includes (1) EASE-psy, a tailored psychotherapy delivered over 8 weeks, and (2) EASE-phys, weekly physical symptom screening over 8 weeks to trigger early palliative care. The primary outcome was traumatic stress symptoms; secondary outcomes included physical symptom burden and quality of life. Assessments were conducted at baseline and at 4, 8, and 12 weeks. Between-group differences were evaluated using multilevel modeling. RESULTS: Forty-two patients were randomized to EASE (n = 22) or UC (n = 20), with 76% retention at 12 weeks. Predefined feasibility outcomes were met: 86% (19/22) of EASE participants completed ≥ 50% of EASE-psy sessions (goal ≥ 64%); 100% received Edmonton Symptom Assessment System (ESAS, modified for AL) screenings, 64% (14/22) of whom completed ≥ 50% of planned screenings (goal ≥50%); and 100% with scores ≥ 4/10 on any physical ESAS-AL item had ≥ 1 meeting with the EASE-phys team (goal 100%). Significant treatment-group differences favoring EASE were observed in traumatic stress symptoms at 4 and 12 weeks, and pain intensity and interference at 12 weeks (all p < .05). CONCLUSIONS: EASE is feasible in patients newly diagnosed with AL and shows promise of effectiveness. These results warrant a larger RCT to provide evidence for its more routine use as a standard of care.

RESUMO

OBJECTIVES: The circumstances of advanced cancer heighten the need for affected individuals to communicate mortality-related concerns, although there may be obstacles to such communication. Managing Cancer and Living Meaningfully(CALM) is a supportive-expressive therapy designed to address such barriers and to facilitate communication of mortality-related concerns in patients and caregivers facing advanced disease. This study explores death-related distress in patients with advanced cancer and the perceived influence of CALM therapy on overcoming barriers to communication of this distress. METHODS: Semistructured interviews were conducted with a subset of patients with advanced cancer (n=17) participating in a CALM phase III trial at a large urban regional cancer centre. Interviews were transcribed, and qualitative data were analysed using thematic analysis. RESULTS: Death-related distress was experienced in terms of three key themes: diffuse and overwhelming fear, fear of uncertainty and fear of suffering. The perceived barriers to communicating such distress were as follows: reluctance of loved ones to discuss mortality-related issues and the participants´ own reluctance to discuss death-related concerns to protect their loved ones or themselves from distress. CALM therapists were perceived to facilitate discussions on dying and death in sessions and to support patients´ communication of death-related distress with healthcare providers and loved ones. CONCLUSIONS: Patients with advanced cancer perceive barriers to effective communication of death distress to be related to their own reluctance, as well as reluctance of their loved ones to address such fears. CALM therapy may help patients with advanced cancer to overcome obstacles to communication and to alleviate death-related distress. TRIAL REGISTRATION NUMBER: NCT01506492.

RESUMO

Objective: We investigated correspondence between symptom severity and symptom bothersomeness in patients with advanced cancer. Background: Symptom severity is commonly assessed in clinical cancer settings, but bothersomeness of these symptoms is less often measured. Methods: Participants with advanced cancer enrolled in a cluster-randomized trial of early palliative care completed the Edmonton Symptom Assessment System (ESAS) and the quality of life at the end of life (QUAL-E) measure as part of their baseline assessment. For each symptom, we examined the correspondence between the symptom being indicated as most severe on the ESAS and rated as most bothersome on the QUAL-E. Results: For the 386 patients who completed relevant sections of the ESAS and QUAL-E, tiredness (32.8%), sleep (23.8%), and appetite (20.2%) were most frequently rated as most severe, whereas pain (28.9%) and tiredness (24.3%) were most frequently indicated as most bothersome. The most bothersome and most severe symptom corresponded in 42%. Pain and/or tiredness were consistently among the top three most bothersome symptoms, whereas appetite was frequently rated the most severe symptom but was rarely perceived as the most bothersome. The probability that patients rating a symptom as most severe would also rate it as most bothersome was highest for pain (66%), nausea (58%), and tiredness (40%). Discussion: ESAS symptom severity does not necessarily indicate patients' most bothersome symptom; regardless of severity, pain and tiredness are most frequently perceived as most bothersome. Further research should investigate the clinical benefits of patients also indicating their three most bothersome ESAS symptoms.

RESUMO

Large panels of comprehensively characterized human cancer models, including the Cancer Cell Line Encyclopedia (CCLE), have provided a rigorous framework with which to study genetic variants, candidate targets, and small-molecule and biological therapeutics and to identify new marker-driven cancer dependencies. To improve our understanding of the molecular features that contribute to cancer phenotypes, including drug responses, here we have expanded the characterizations of cancer cell lines to include genetic, RNA splicing, DNA methylation, histone H3 modification, microRNA expression and reverse-phase protein array data for 1,072 cell lines from individuals of various lineages and ethnicities. Integration of these data with functional characterizations such as drug-sensitivity, short hairpin RNA knockdown and CRISPR-Cas9 knockout data reveals potential targets for cancer drugs and associated biomarkers. Together, this dataset and an accompanying public data portal provide a resource for the acceleration of cancer research using model cancer cell lines.

RESUMO

This study was to determine the degree of posttraumatic enophthalmos that is detectable by lay observers. In this case-control study, 60 photographs (frontal and oblique angles) of patients from an oculoplastics registry at the authors' institution were reviewed by lay observers. Patients were included if they had between 1 and 5 mm of unilateral enophthalmos, at least 6 months following trauma. They were divided into five groups of 10 and each group was separated by increments of 1 mm. Controls were selected from the same database and had 0 mm difference between each eye. Patients were excluded if they had any medical condition that might cause enophthalmos (including use of prostaglandin analogues). Participants were also excluded if they had any medical or surgical condition affecting the contralateral side. Lay observers were randomly selected from a pool of volunteers in nonmedical programs at our affiliated university. The primary outcome measure was the asymmetry cut-off (in millimeters) in which more than 50% of the cases (chance) were identified correctly. The generalized mixed model predicts that 66% of lay observers would correctly identify a difference between both eyes at a rate greater than would be predicted by chance, if at least a 5 mm difference existed between them (95% confidence interval [CI] 55.5-75%). This study shows that lay observers only reliably detect unilateral enophthalmos when there is at least a 5 mm difference between the eyes. This study used two-dimensional (2D) photographs and, therefore, results with three-dimensional (3D) observation may be different. In this study of 2D photographs, unilateral posttraumatic enophthalmos is only reliably detected by lay observers when a 5 mm difference exists between the eyes.

RESUMO

PURPOSE: To investigate the safety and efficacy of direct, intralesional doxycycline hyclate injection for improving the appearance of cosmetically significant lower eyelid festoons and malar edema. METHODS: An Institutional Review Board approved, retrospective review was performed of 15 consecutive patients with malar edema and/or festoons injected with doxycycline hyclate at a concentration of 10 mg/ml. Pre- and postinjection photographs were reviewed and graded on a scale of 0 to 3 (0: no festoon; 1: small festoon; 2: medium festoon; 3: large festoon) by 2 masked physician observers. Patients were excluded from the final analysis if they received an alternate dose concentration, had incomplete photographic records, or did not follow up. Student t test was used for statistical analysis. RESULTS: Twenty consecutive treatment areas of 11 patients were included in the analysis. Final follow up ranged from 3 to 104 weeks, with a mean follow up of 22.5 weeks. The average (standard deviation) initial festoon grade of 2.5 (0.58) decreased to 0.9 (0.82) with a p value of <0.001. The average number of injections performed per side was 1.4 (range: 1-2). The mean volume per injection was 0.72 ml (range: 0.15-2.0 ml). Commonly documented subjective complaints were burning sensation with injection, pain, bruising, and erythema. There were no other dermatologic or visual complications following treatment. CONCLUSIONS: These preliminary results suggest that intralesional injections of doxycycline hyclate at a concentration of 10 mg/ml may be an effective treatment option for cosmetically significant lower eyelid festoons and malar edema. Future prospective studies with increased patient numbers, increasing concentrations, combination therapies with local anesthetic or regional nerve blocks, and longer follow up are needed to validate these results and determine optimal injection technique.

RESUMO

BACKGROUND: Tumor content in circulating cell-free DNA (cfDNA) is a promising biomarker, but longitudinal dynamics of tumor-derived and non-tumor-derived cfDNA through multiple courses of therapy have not been well described. METHODS: CfDNA from 663 plasma samples from 140 patients with castration-resistant prostate cancer (CRPC) was subject to sparse whole genome sequencing. Tumor fraction (TFx) estimated using the computational tool ichorCNA was correlated with clinical features and responses to therapy. RESULTS: TFx associated with the number of bone metastases (median TFx = 0.014 with no bone metastases, 0.047 with 1-3 bone metastases, 0.190 for 4+ bone metastases; P < 0.0001) and with visceral metastases (P < 0.0001). In multivariable analysis, TFx remained associated with metastasis location (P = 0.042); TFx was positively correlated with alkaline phosphatase (P = 0.0227) and negatively correlated with hemoglobin (Hgb) (P < 0.001), but it was not correlated with prostate specific antigen (PSA) (P = 0.75). Tumor-derived and non-tumor-derived cfDNA track together and do not increase with generalized tissue damage from chemotherapy or radiation at the time scales examined. All new treatments that led to ≥30% PSA decline at 6 weeks were associated with TFx decline when baseline TFx was >7%; however, TFx in patients being subsequently maintained on secondary hormonal therapy was quite dynamic. CONCLUSION: TFx correlates with clinical features associated with overall survival in CRPC, and TFx decline is a promising biomarker for initial therapeutic response.

RESUMO

OBJECTIVE: The circumstances of advanced cancer can cause considerable psychological distress, including death anxiety and demoralization. Although these states of existential distress have a negative impact on the quality of life of patients with advanced cancer, they are rarely evaluated as outcomes or targets of interventions in this population. In an effort to improve understanding of existential distress, a structural model of relationships among death anxiety, demoralization, symptom burden, and social relatedness was tested in patients with advanced cancer. METHODS: A total of 307 patients with advanced cancer completed baseline measures including the Death and Dying Distress Scale, the Demoralization Scale, the modified Experiences in Close Relationships Scale, the Life Completion subscale of the Quality of Life Evaluation-Cancer scale, the Memorial Symptom Assessment Scale, and Karnofsky Performance Status. A structural equation model of protective and risk factors for demoralization and death anxiety was tested. RESULTS: The final model had good fit (SRMR = 0.061; RMSEA = 0.077; CFI = 0.927; NNFI = 0.902) in which death anxiety was positively associated with demoralization (ß = 0.71), and demoralization was positively associated with symptom burden (ß = 0.31) and negatively associated with social relatedness (ß = -0.74). CONCLUSIONS: The findings of this study suggest that demoralization and death anxiety are closely linked in patients with advanced cancer. The contribution of both symptom burden and low social relatedness to demoralization suggests that an integrated intervention addressing both physical and psychosocial disease factors may be most effective at alleviating such states of existential distress.

RESUMO

Purpose Individuals with advanced cancer experience substantial distress in response to disease burden and impending mortality. Managing Cancer And Living Meaningfully (CALM) is a novel, brief, manualized psychotherapeutic intervention intended to treat and prevent depression and end-of-life distress in patients with advanced cancer. We conducted a randomized controlled trial to compare CALM with usual care (UC) in this population. Methods Patients with advanced cancer were recruited from outpatient oncology clinics at a comprehensive cancer center into an unblinded randomized controlled trial. Permuted block randomization stratified by Patient Health Questionnaire-9 depression score allocated participants to CALM plus UC or to UC alone. Assessments of depressive symptoms (primary outcome), death-related distress, and other secondary outcomes were conducted at baseline, 3 months (primary end point), and 6 months (trial end point). Analyses were by intention to treat. Analysis of covariance was used to test for outcome differences between groups at follow-up, controlling for baseline. Mixed-model results are reported. Results Participants (n = 305) were recruited between February 3, 2012, and March 4, 2016, and randomly assigned to CALM (n = 151) or UC (n = 154). CALM participants reported less-severe depressive symptoms than UC participants at 3 months (Δ = 1.09; P = .04; Cohen's d = 0.23; 95% CI, 0.04 to 2.13) and at 6 months (Δ = 1.29; P = .02; d = 0.29; 95% CI, 0.24 to 2.35). Significant findings for greater end-of-life preparation at 6 months also favored CALM versus UC. No adverse effects were identified. Conclusion Findings suggest that CALM is an effective intervention that provides a systematic approach to alleviating depressive symptoms in patients with advanced cancer and addresses the predictable challenges these patients face.

RESUMO

T- and NK-cell lymphomas (TCL) are a heterogenous group of lymphoid malignancies with poor prognosis. In contrast to B-cell and myeloid malignancies, there are few preclinical models of TCLs, which has hampered the development of effective therapeutics. Here we establish and characterize preclinical models of TCL. We identify multiple vulnerabilities that are targetable with currently available agents (e.g., inhibitors of JAK2 or IKZF1) and demonstrate proof-of-principle for biomarker-driven therapies using patient-derived xenografts (PDXs). We show that MDM2 and MDMX are targetable vulnerabilities within TP53-wild-type TCLs. ALRN-6924, a stapled peptide that blocks interactions between p53 and both MDM2 and MDMX has potent in vitro activity and superior in vivo activity across 8 different PDX models compared to the standard-of-care agent romidepsin. ALRN-6924 induced a complete remission in a patient with TP53-wild-type angioimmunoblastic T-cell lymphoma, demonstrating the potential for rapid translation of discoveries from subtype-specific preclinical models.
