Successful treatment of an unresectable choroid plexus carcinoma in a patient with Li-Fraumeni syndrome

Choroid plexus carcinoma (CPC) is an uncommon central nervous system tumor requiring complete surgical excision for favorable outcome. The authors report the successful treatment of a 2-year-old patient with widely disseminated CPC and Li-Fraumeni syndrome. Following a partial resection of the tumor the patient received chemotherapy consisting of cyclophosphamide, etoposide, and carboplatin. There were no additional surgical procedures and radiation was not administered. Remarkably, the patient remains without evidence of active disease more than 3 years from the completion of therapy. Additional studies are necessary to determine whether this treatment plan can be beneficial to other patients with CPC and whether the patient's p53 mutation had an effect on outcome.     

Intracoronary fibrin-specific thrombolytic infusion facilitates percutaneous recanalization of chronic total occlusion

OBJECTIVES: We sought to investigate the benefit, predictors of procedural success, and safety of pre-procedural intra-coronary fibrin-specific lytic infusion (ICL) in patients with failed prior percutaneous coronary intervention (PCI) for chronic total occlusions (CTO). BACKGROUND: Percutaneous coronary intervention for CTO remains a challenge with a high incidence of procedural failure secondary to inability to cross the occlusion with the guidewire. METHODS: Eighty-five patients who underwent unsuccessful PCI procedures of CTO (more than three months' duration) had a repeat attempt of recanalization with the use of pre-procedural ICL. Patients received a weight-adjusted dose of either alteplase (tPA) (2 to 5 mg/h) or tenecteplase (TNK) (0.5 mg/h) for a total of 8 h. The total dose of ICL therapy was infused split between the guiding catheter and an intracoronary infusion catheter. A step-down multivariate logistic regression analysis was completed to determine the best predictors of procedural success. In-hospital major adverse cardiac events (MACE) including myocardial infarction, acute reocclusion, stroke, and death, as well as bleeding complications, were also examined. RESULTS: The procedure was successful in 46 of 85 cases (54%). Four of 85 (5%) contained dissections that did not result in perforations, tamponade, or MACE. The incidence of groin complications was 7 of 85 (8%) and of bleeding complications requiring transfusions was 3 of 85 (3.5%). On multivariate analysis, predictors of success were tapering morphology (odds ratio, 15.5; 95% confidence interval, 3.73 to 63; p = 0.0002) and lack of bridging collaterals (odds ratio, 5.08; 95% confidence interval, 1.53 to 17; p = 0.008). CONCLUSIONS: Intracoronary infusion of fibrin-specific thrombolytic therapy may provide a valuable and safe option for facilitating percutaneous revascularization of CTO.     

Motivations for physician-assisted suicide

OBJECTIVE: To obtain detailed narrative accounts of patients' motivations for pursuing physician-assisted suicide (PAS). DESIGN: Longitudinal case studies. PARTICIPANTS: Sixty individuals discussed 35 cases. Participants were recruited through advocacy organizations that counsel individuals interested in PAS, as well as hospices and grief counselors. SETTING: Participants' homes. MEASUREMENTS AND RESULTS: We conducted a content analysis of 159 semistructured interviews with patients and their family members, and family members of deceased patients, to characterize the issues associated with pursuit of PAS. Most patients deliberated about PAS over considerable lengths of time with repeated assessments of the benefits and burdens of their current experience. Most patients were motivated to engage in PAS due to illness-related experiences (e.g., fatigue, functional losses), a loss of their sense of self, and fears about the future. None of the patients were acutely depressed when planning PAS. CONCLUSIONS: Patients in this study engaged in PAS after a deliberative and thoughtful process. These motivating issues point to the importance of a broad approach in responding to a patient's request for PAS. The factors that motivate PAS can serve as an outline of issues to explore with patients about the far-reaching effects of illness, including the quality of the dying experience. The factors also identify challenges for quality palliative care: assessing patients holistically, conducting repeated assessments of patients' concerns over time, and tailoring care accordingly.
