Desmoplastic Small Round Cell Tumor With Ascending Intraspinal Metastasis at Recurrence: Case Report and Review of the Literature.

BACKGROUND: Desmoplastic small round cell tumor (DSRCT) is a rare and aggressive malignancy commonly involving the abdomen and/or pelvic peritoneum. Despite aggressive therapy, the prognosis remains poor. Central nervous system relapse is rare in abdominal/pelvic primary DSRCT. OBSERVATION: We report a case of a 10-year-old female with a large pelvic DSRCT and involvement of the rectosigmoid colon and liver. Following treatment with chemotherapy, and cytoreductive surgery with hyperthermic intraperitoneal chemotherapy an initial response was noted. With progressive lower limb weakness, recurrence with perineural invasion in the lumbosacral nerve root involving the conus was noted 2.5 years from diagnosis. Cerebrospinal fluid showed tumor cells with a molecular confirmation. CONCLUSIONS: Perineural invasion and ascending paralysis secondary to primary abdominal DSRCT has not been previously reported to our knowledge. We recommend a high index of suspicion for early and accurate diagnosis of this rare presentation.

Online Education and Cognitive Behavior Therapy Improve Dementia Caregivers' Mental Health: A Randomized Trial.

OBJECTIVES: To compare online cognitive-behavioral therapy (CBT) with and without telephone support respectively to online psychoeducation in a randomized controlled trial (RCT) in caregivers of people with dementia with mild anxiety or depression. DESIGN: Three-arm parallel-group RCT comparing online CBT with and without telephone support respectively to online psychoeducation. SETTING AND PARTICIPANTS: Online study with caregivers of people with dementia. MEASURES: The primary outcome measure was mental health measured by General Health Questionnaire-12 (GHQ-12) at 26 weeks. Secondary outcomes included the Hospital Anxiety and Depression Scale (HADS); the Relative Stress Scale (RSS) and the Short Sense of Competency Questionnaire. The primary analysis focused on people completing GHQ-12 at both baseline and 26 weeks, evaluated using analysis of covariance. RESULTS: 638 people were randomized to the 3 treatment arms, of whom 208 were included in the analysis population. There were significant improvements in GHQ-12 in all treatment arms compared to baseline (P < .001 for all interventions), but neither CBT with nor without telephone support conferred any significant advantage compared to psychoeducation. For the secondary outcomes, there were no significant differences between CBT with telephone support and psychoeducation, but CBT without telephone support was less effective than psychoeducation with respect to HADS depression subscale [mean difference 1.86, 95% confidence interval (CI) 0.61, 3.11; P = .004] and caregiver stress (RSS mean difference 3.11, 95% CI 0.13, 6.09; P = .04). Good safety was achieved in all 3 treatment arms, with no deaths or serious adverse events. CONCLUSIONS AND IMPLICATIONS: Online CBT with telephone support and psychoeducation both achieved significant benefits over 26 weeks compared with baseline in mental health and mood, but there were no advantages for CBT compared with the psychoeducation intervention. CBT without telephone support was less effective with respect to mood outcomes than psychoeducation and should not be recommended based on current evidence.

Feasibility and safety of delivering full-dose anticoagulation therapy in children treated according to Dana-Farber Cancer Institute acute lymphoblastic leukemia consortium therapy protocols.

BACKGROUND: The literature is void of an evidence-based anticoagulation therapy (ACT) management strategy in the context of thrombocytopenia. We examined the impact of thrombocytopenia on low-molecular-weight heparin (LMWH) dosing and incidence of bleeding in children with acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LL) who developed thromboembolism (TE) during therapy according to DFCI ALL protocols. PROCEDURE: Patient records from our tertiary care center were reviewed for demographics, details of diagnoses and therapy of ALL/LL and TE diagnoses, platelet counts during ACT, LMWH dosing, and bleeding episodes. RESULTS: Thirty-nine TEs were diagnosed in 33 patients [mean age 9 years (range, 2.5-18); 16 males and 31 with ALL] during the study period. A majority (85%) of patients were diagnosed with TE in the consolidation phase with mean time to TE 5.75 months from ALL/LL diagnosis. All patients received LMWH, and the median duration of ACT was 5.9 months (range, 1-11 months). Platelets were measured weekly. On 29 occasions, platelet nadir was <50 × 109 /L, and twice it was < 20 × 109 /L. One (3%) patient had major bleeding episode while on ACT. Platelet count at the time of bleeding was 222 × 109 /L. Ninety-two procedures [83 lumbar punctures (LPs), 9 central venous line (CVL) insertion/revision] were completed without bleeding complications. Asparaginase was held temporarily with TE diagnosis in 48% of patients; most (88%) patients completed all scheduled doses as per protocol. CONCLUSIONS: Ability to administer full-dose LMWH, expected bleeding rate, and completion of asparaginase doses while on ACT suggest full-dose ACT is feasible and safe in children with ALL/LL who develop TE during DFCI ALL consortium therapy protocols.

Need and Use of Healthcare Services in Survivors of Hodgkin Lymphoma.

PURPOSE: Hodgkin lymphoma (HL) is the commonest cancer in adolescents and young adults (AYAs), aged 15-29 years. While the survival rate is high, many survivors experience adverse late effects of therapy. Yet, this age group in general makes limited use of health services. This study sought to determine whether the need for health services by HL survivors was mismatched to their health service utilization, as hypothesized a priori. METHODS: A population-based cohort of survivors (N = 43) younger than 39 years of age was sent a mailed survey for self-assessment of need, as expressed in health-related quality of life (HRQOL), and utilization of health services by validated instruments; the Health Utilities Index and Health and Social Service Utilization Survey, respectively. Survivors who were AYAs at diagnosis were compared to children and older adults. RESULTS: AYAs had the lowest mean HRQOL score (0.79 on a scale of 0.00-1.00) compared to children (0.86) and older adults (0.94)-clinically meaningful differences. The difference in the single attribute score for cognition reached statistical significance (0.89 vs. 0.99 vs. 1.00, p = 0.02). AYAs also had lower mean overall annual costs for health services (CAN$601) than children (CAN$753) and older adults (CAN$936) did. CONCLUSIONS: Survivors of HL who were AYAs at diagnosis had a mismatch between high need for and low utilization of health services. Providers of healthcare to this population should be made aware of this discrepancy, and the survivors should be encouraged to seek the health services they need.
