RESUMEN

PURPOSE: Automated scalp cooling (ASC) is available to patients undergoing chemotherapy for breast cancer to decrease chemotherapy-induced alopecia. This study sought to elucidate patient and chemotherapy nursing perspectives on the ASC experience. METHODS: This is a survey-based study of chemotherapy nursing staff and patients with breast cancer regarding perceived efficacy, side effects, administration, support, and overall opinions of ASC. Chemotherapy nurses across a large, multi-regional tertiary healthcare system completed a one-time survey regarding their experiences in administering ASC. Breast cancer patients who utilized ASC were surveyed along with a control group who underwent alopecia-inducing chemotherapy without ASC use for comparison. RESULTS: The majority of nursing responses reported inadequate technical support, an increased burden of administering ASC compared to other clinical duties, and that they would not recommend ASC to a family member or friend. Patients who underwent ASC reported significantly less hair loss and were significantly less likely to shave their heads or wear a wig, but this did not translate into significant differences in body image or psychosocial wellbeing responses. Time investment was the most significant burden related to ASC. CONCLUSION: Patients using ASC reported significantly less hair loss compared to those not using ASC during alopecia-inducing breast cancer chemotherapy, but this did not translate to improved body image. The majority of chemotherapy nurses reported they lacked adequate support in administering ASC and would not recommend it. Enhanced nursing support may provide a means for improving the ASC experience for both nursing staff and patients.

RESUMEN

This manuscript describes a novel approach for treating patients with long-term sequelae from hemoglobin Evans (Hb Evans). After instituting conservative therapies for approximately 2 years, our patient's symptoms continually worsened. Therefore, we performed red blood cell exchange (RBCx) to reduce his Hb Evans percentage and his co-existing elevation of methemoglobin. Our assumptions of clinical benefit were based on our collective experience performing RBCx for patients with sickle cell disease. After the first exchange, pre- and post-laboratory results supported our approach and the patient experienced marked improvement in his clinical signs and symptoms. This report provides preliminary proof of principle for the use of RBCx to treat Hb Evans and other non-Hb S hemoglobinopathies.

RESUMEN

IMPORTANCE: Hereditary factors play a key role in the risk of developing several cancers. Identification of a germline predisposition can have important implications for treatment decisions, risk-reducing interventions, cancer screening, and germline testing. OBJECTIVE: To examine the prevalence of pathogenic germline variants (PGVs) in patients with cancer using a universal testing approach compared with targeted testing based on clinical guidelines and the uptake of cascade family variant testing (FVT). DESIGN, SETTING, AND PARTICIPANTS: This prospective, multicenter cohort study assessed germline genetic alterations among patients with solid tumor cancer receiving care at Mayo Clinic cancer centers and a community practice between April 1, 2018, and March 31, 2020. Patients were not selected based on cancer type, disease stage, family history of cancer, ethnicity, or age. EXPOSURES: Germline sequencing using a greater than 80-gene next-generation sequencing platform. MAIN OUTCOMES AND MEASURES: Proportion of PGVs detected with a universal strategy compared with a guideline-directed approach and uptake of cascade FVT in families. RESULTS: A total of 2984 patients (mean [SD] age, 61.4 [12.2] years; 1582 [53.0%] male) were studied. Pathogenic germline variants were found in 397 patients (13.3%), including 282 moderate- and high-penetrance cancer susceptibility genes. Variants of uncertain significance were found in 1415 patients (47.4%). A total of 192 patients (6.4%) had incremental clinically actionable findings that would not have been detected by phenotype or family history-based testing criteria. Of those with a high-penetrance PGV, 42 patients (28.2%) had modifications in their treatment based on the finding. Only younger age of diagnosis was associated with presence of PGV. Only 70 patients (17.6%) with PGVs had family members undergoing no-cost cascade FVT. CONCLUSIONS AND RELEVANCE: This prospective, multicenter cohort study found that universal multigene panel testing among patients with solid tumor cancer was associated with an increased detection of heritable variants over the predicted yield of targeted testing based on guidelines. Nearly 30% of patients with high-penetrance variants had modifications in their treatment. Uptake of cascade FVT was low despite being offered at no cost.

RESUMEN

PURPOSE OF REVIEW: In this review article, we will highlight ethical issues faced by hematologists due to a growing constellation of expensive diagnostics and therapeutics in hematology. We outline the important issues surrounding this topic including stakeholders, cost considerations, and various ethical challenges surrounding access to care, communication about costs, and individual vs. societal responsibilities. We review available tools to navigate these ethical themes and offer potential solutions. RECENT FINDINGS: We identified several gaps in the literature on the topic of ethical issues in hematology treatment and supplement by non-hematological cancer and general medical literature. We propose proactive solutions to address these problems to include cost transparency, utilization of evidence-based decision making tools, application of the four quadrant approach to ethical care, and advanced systems-based practice curriculum for physician trainees.

RESUMEN

OBJECTIVE: To evaluate the incidence of and characterize the presentation of neuropsychiatric symptoms and/or Parkinsonism as a presentation of central nervous system lymphoma (CNSL) in either its primary CNSL form or when it spreads to the brain in systemic diffuse large B-cell lymphoma (secondary CNSL). PATIENTS AND METHODS: With Institutional Review Board approval we identified patients who had been treated at Mayo Clinic from 1998 to 2018 and were recorded to have a combination of ICD 9/10 codes for CNSL and various psychiatric diagnoses. RESULTS: A total of 20 of the 232 patients (9%) were noted to have neuropsychiatric symptoms preceding diagnosis. The average age at diagnosis was 62, with even split for sex. The majority (85%) of patients had primary CNSL. The average duration of symptoms before the diagnosis was 4.8 months. Confusion (80%), depression (40%), apathy (30%), anxiety (30%), and agitation (30%) were the most common symptoms identified. The majority (65%) of patients had subcortical lesions followed by the frontal lobe (50%). Parkinsonism was identified in 5 of the 20 patients with 4 demonstrating resolution of symptoms with treatment of the lymphoma. CONCLUSIONS: Neuropsychiatric symptoms are a rare but notable symptom before the presentation of CNSL. There is an increasing awareness of neurological illness presenting as pure psychiatric disturbance, prompting the need to exclude organic and treatable diseases, particularly in elderly patients. Acknowledgment and diagnosis are important for an appropriate management as there is a significant impact on patient and caregiver quality of life.

RESUMEN

PURPOSE: Survivors of estrogen receptor-expressing breast cancer generally do not receive estrogen-based therapy for menopausal symptoms due to concern for provoking recurrence of disease. Single-dose depomedroxyprogesterone acetate has been shown to be among the most effective non-estrogen strategies for treatment of menopausal hot flashes, but long-term evidence for safety in survivors is lacking. METHODS: We conducted an institutional review board approved, retrospective, case-control cohort study at a tertiary, academic referral center. Patients with estrogen receptor-expressing early-stage operable breast cancer who received depomedroxyprogesterone acetate for hot flashes between January 2005 and December 2012 were identified. We confirmed 75 patients who met strict inclusion criteria who were matched 1:1 with controls for age, stage of disease, HER2 status, and year of diagnosis. Overall survival, loco-regional recurrence-free survival, and progression-free survival assessments for cases were compared with controls. RESULTS: Median follow-up duration was 68.4 months in cases and 57.6 months in controls. Estimated local-regional recurrence-free survival at 10 years was 97% (95% CI, 92-100%) in cases and 98% (95% CI, 95-100%) in controls. Estimated progression-free survival at 10 years was 89% (95% CI, 80-100%) in cases and 83% (95% CI, 73-95) in controls. The majority (75%) of case patients experienced satisfactory relief of hot flashes from depomedroxyprogesterone injection. DISCUSSION: In this retrospective case-control study, we were unable to identify a detrimental effect of depomedroxyprogesterone acetate therapy for hot flashes in survivors of estrogen receptor-expressing breast cancer. Depomedroxyprogesterone acetate may be acceptable for management of hot flashes in this population.

RESUMEN

Hyperbilirubinemia in the setting of stent-intolerant biliary obstruction is a challenging problem and can prevent cancer patients from pursuing additional treatments such as further systemic therapies. We report a case of a 75-year-old female who underwent treatment with palliative radiotherapy (RT) for relieving persistent biliary obstruction secondary to liver metastases from colorectal disease, despite prior appropriate stent placement. Prior to RT, the patient's total bilirubin was 14.6 mg/dL, and she experienced fatigue, diarrhea, nausea, vomiting, and severe jaundice. After treatment with 37.5 Gy in 15 once daily fractions, total bilirubin decreased to 3.9 mg/dL, with resolution of previous symptoms including jaundice and pruritus. The patient did not experience any significant treatment-related toxicities. This case, along with a succinct literature review, demonstrates that palliative RT can be successful in relieving biliary obstruction unrelieved by biliary stent. Further research is required to evaluate the efficacy of RT in palliating biliary obstruction for liver metastases in a general population.

RESUMEN

Based on the current WHO Classification of Myeloid Neoplasms, cytogenetic findings play a central role in the diagnostic classification of the myeloid malignancies. Cytogenetic abnormalities detected at primary diagnosis may change over time. Karyotype changes can be characterized as cytogenetic evolution, cytogenetic regression or a combination of both. While the exact mechanism of cytogenetic evolution is not completely understood, the process of cytogenetic evolution is not random, but follows different, and often disease-specific patterns during progression and relapse of myeloid neoplasms. Important lessons were learned from the cytogenetic evolution pathways observed over the course of chronic myelogenous leukemia (CML), progressing through chronic phase into accelerated phase and blast crisis. Cytogenetic evolution pathways of CML are divided into major and minor route abnormalities. The major route changes include an extra Ph chromosome (+Ph) trisomy 8 (+8) and the occurrence of an i(17q). The six most common minor route abnormalities include -7, -17, +17, +21 and -Y and one structural change, t(3;21). Recently an increased number of CML cases with karyotype abnormalities in Ph-negative cells have been reported in patients treated with imatinib. These abnormalities include trisomy 8, abnormalities of chromosome 7, and chromosome 20. The significance of the Ph-negative karyotype changes in subsequent development of myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) is unclear. Nevertheless, the occurrence of clonal abnormalities in Ph-negative cells underlines the importance of conventional cytogenetic studies in monitoring of CML patients. In AML, karyotype changes commonly occur between diagnosis and relapse status post chemotherapy. Karyotype evolution seems more common in patients who had unfavorable aberrations at diagnosis as compared to patients with favorable or intermediate abnormalities. Karyotype evolution results in shortened remission duration as compared to cases without cytogenetic change. Recent studies on cytogenetic evolution at relapse after allogeneic hematopoietic cell transplantation (allo-HCT) were similar to the data observed in chemotherapy-treated AML. Serial bone marrow evaluations after allo-HCT offer insights into the dynamics of karyotype evolution, notably, they demonstrated that a detection of karyotype abnormalities is usually followed by a relapse within the next 90 days. As a contrast, karyotype abnormalities were not observed in patients who do not relapse in the next 3 months. CGE at relapse was associated with significantly decreased postrelapse and post-transplantation survival compared with the non-CGE group. Very few data exist regarding a potential association between the dose or certain types of chemotherapy and cytogenetic evolution. Based on the results of a single study conducted recently, no specific chemotherapy regimen emerged to predispose for cytogenetic evolution. Further studies are necessary to evaluate the impact of the altered bone marrow environment and immunosuppression on karyotype stability.

RESUMEN

AIM: To review microbiome alterations associated with pancreatic cancer, its potential utility in diagnostics, risk assessment, and influence on disease outcomes. METHODS: A comprehensive literature review was conducted by all-inclusive topic review from PubMed, MEDLINE, and Web of Science. The last search was performed in October 2016. RESULTS: Diverse microbiome alterations exist among several body sites including oral, gut, and pancreatic tissue, in patients with pancreatic cancer compared to healthy populations. CONCLUSION: Pilot study successes in non-invasive screening strategies warrant further investigation for future translational application in early diagnostics and to learn modifiable risk factors relevant to disease prevention. Pre-clinical investigations exist in other tumor types that suggest microbiome manipulation provides opportunity to favorably transform cancer response to existing treatment protocols and improve survival.

RESUMEN

IMPORTANCE: Therapy-related myeloid neoplasms are a potentially life-threatening consequence of treatment for autoimmune disease (AID) and an emerging clinical phenomenon. OBJECTIVE: To query the association of cytotoxic, anti-inflammatory, and immunomodulating agents to treat patients with AID with the risk for developing myeloid neoplasm. DESIGN, SETTING, AND PARTICIPANTS: This retrospective case-control study and medical record review included 40 011 patients with an International Classification of Diseases, Ninth Revision, coded diagnosis of primary AID who were seen at 2 centers from January 1, 2004, to December 31, 2014; of these, 311 patients had a concomitant coded diagnosis of myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML). Eighty-six cases met strict inclusion criteria. A case-control match was performed at a 2:1 ratio. MAIN OUTCOMES AND MEASURES: Odds ratio (OR) assessment for AID-directed therapies. RESULTS: Among the 86 patients who met inclusion criteria (49 men [57%]; 37 women [43%]; mean [SD] age, 72.3 [15.6] years), 55 (64.0%) had MDS, 21 (24.4%) had de novo AML, and 10 (11.6%) had AML and a history of MDS. Rheumatoid arthritis (23 [26.7%]), psoriasis (18 [20.9%]), and systemic lupus erythematosus (12 [14.0%]) were the most common autoimmune profiles. Median time from onset of AID to diagnosis of myeloid neoplasm was 8 (interquartile range, 4-15) years. A total of 57 of 86 cases (66.3%) received a cytotoxic or an immunomodulating agent. In the comparison group of 172 controls (98 men [57.0%]; 74 women [43.0%]; mean [SD] age, 72.7 [13.8] years), 105 (61.0%) received either agent (P = .50). Azathioprine sodium use was observed more frequently in cases (odds ratio [OR], 7.05; 95% CI, 2.35- 21.13; P < .001). Notable but insignificant case cohort use among cytotoxic agents was found for exposure to cyclophosphamide (OR, 3.58; 95% CI, 0.91-14.11) followed by mitoxantrone hydrochloride (OR, 2.73; 95% CI, 0.23-33.0). Methotrexate sodium (OR, 0.60; 95% CI, 0.29-1.22), mercaptopurine (OR, 0.62; 95% CI, 0.15-2.53), and mycophenolate mofetil hydrochloride (OR, 0.66; 95% CI, 0.21-2.03) had favorable ORs that were not statistically significant. No significant association between a specific length of time of exposure to an agent and the drug's category was observed. CONCLUSIONS AND RELEVANCE: In a large population with primary AID, azathioprine exposure was associated with a 7-fold risk for myeloid neoplasm. The control and case cohorts had similar systemic exposures by agent category. No association was found for anti-tumor necrosis factor agents. Finally, no timeline was found for the association of drug exposure with the incidence in development of myeloid neoplasm.

RESUMEN

Cytogenetic evolution (CGE) in patients with myeloid neoplasms who relapsed after an allogeneic (allo) hematopoietic cell transplantation (HCT) has been evaluated by only few studies. The effect of the CGE on survival of relapsed allo-HCT recipients is not clear. The effect of previously received chemotherapy to induce CGE in this patient population has not been studied. The aims of our study are to (1) characterize the patterns of cytogenetic change in patients with myeloid neoplasms who relapsed after an allo-HCT, (2) evaluate the effect of CGE on survival, and (3) explore the association of CGE with previous chemotherapy (including the lines of salvage therapy, type of induction, and conditioning therapy). Of 49 patients with a myeloid malignancy (27 acute myeloid leukemia [AML], 19 myelodysplastic syndrome [MDS]/myeloproliferative neoplasm [MPN], and 3 chronic myelogenous leukemia) who relapsed after an allo-HCT, CGE was observed in 25 (51%), whereas 24 patients had unchanged cytogenetic findings at relapse. The CGE group carried more cytogenetic abnormalities at original diagnosis. The most frequent cytogenetic change was the acquisition of 3 or more new chromosomal abnormalities followed by acquisition of unbalanced abnormalities, aneuploidy, and emergence of apparently new clones unrelated to the original clone. The CGE cohort had higher proportion of MDS and MPN and fewer patients with de novo AML. Disease risk assessment category showed a trend to higher frequency of high-risk patients in the CGE group, though the difference was not statistically significant. Time from diagnosis to transplantation and time from transplantation to relapse were not different between the CGE and non-CGE groups. CGE and non-CGE cohorts had similar exposures to salvage therapy and to induction chemotherapy, as well as similar conditioning regimens; thus, no particular type of chemotherapy emerged as a predisposing factor to CGE. CGE was associated with significantly shortened post-transplantation and postrelapse survival when compared with those of the non-CGE group (P = .004 and P < .001, respectively). Our results underscore the significance of CGE in progression of myeloid malignancies after an allo-HCT.

RESUMEN

Paragangliomas (PGLs) are rare, extra-adrenal tumors, originating from neural crest cells and can occur anywhere from the skull base to the pelvic floor. Although these tumors are often benign, a fraction of malignant cases exist. Few isolated cases of malignant head and neck PGL are reported in the literature. Treatment algorithms rely heavily on retrospective case studies and institutional experience. We report an unusual case of an extensive, hereditary PGL, with invasive characteristics, that was refractory to radiation therapy. An operative approach was selected for recurrent disease in the setting of critical neurovascular structure compromise. Six months postoperatively, the patient was recovering as expected and had no evidence of recurrent disease. We propose a modified treatment algorithm based on an updated literature review that encompasses the spectrum of PGL, from benign and asymptomatic to invasive and malignant disease.
