Radiation-induced sarcoma (RIS) has been reported as a late secondary malignancy following radiotherapy for various types of cancer with a median latency of 10 years. We describe an early RIS that developed in an adolescent within three years of treatment (including PD-L1 check-point inhibitor Nivolumab) of a relapsed classic Hodgkin lymphoma (HL) and was diagnosed post-mortem. The patient died of the progressive RIS that was misleadingly assumed to be a resistant HL based on the positive PET/CT scan. Repetitive tumor biopsies are warranted in cases of aggressive and multi-drug resistant HL to validate imaging findings, ensure correct diagnosis and avoid overtreatment.
Background: Neurological deterioration (ND) after mechanical thrombectomy (MT) of acute ischemic stroke (AIS) in anterior circulation is an important complication associated with a poor outcome. Moreover, evident causes of ND may remain unexplained (UnND). Objective: We sought to evaluate the association of the systolic blood pressure (SBP) parameters before MT, during MT, and during a 24-h period after MT with UnND. Methods: We analyzed 382 MT-treated AIS patients in two stroke centers from 2017 to 2019. The patients with unsuccessful recanalization and/or with symptomatic intracerebral hemorrhage after MT were excluded. Multivariate logistic regression analysis was used to identify the SBP parameters that predict UnND. Results: There were 5.9% patients with UnND within 24 h after MT among patients with successful recanalization what comprises 4.9% of all patients who had undergone MT. SBP > 180 mmHg on admission (odds ratio (OR): 4, 95% confidence interval (CI): 1.6–10, p = 0.004) and a drop of SBP below100 mmHg during MT (OR: 4.7, 95% CI: 1.3–17, p = 0.019) were associated with UnND occurrence within 7 days without a significant association with UnND within 24 h. UnND within 7 days was predicted by the episodes of SBP exceeding the level of SBP observed before the groin puncture and occurring over the first 2 h following recanalization (OR: 5, 95% CI: 1.3–19, p = 0.021), an increase of SBP of more than 20% within 2–24 h after MT (OR: 3.4, 95% CI: 1.1–10, p = 0.035), and a drop of SBP below 100 mmHg after MT (OR: 3.2, 95% CI: 1.1–9, p = 0.039). Conclusion: The association between the SBP parameters and UnND depends on the treatment period and the time of UnND occurrence. The J/U resembling relationship between SBP and UnEND was established during a 24-h period after MT.
Background: Pediatric very rare tumors (VRTs) represent a heterogeneous subset of childhood malignancies, with reliable survival rate estimations depending dramatically on each (un)registered case. The current study aimed to evaluate the number of VRTs among Lithuanian children and the change in treatment outcome over the 16 year study period as well as to assess the impact of the registration status on survival estimation. Methods . We performed a population-based retrospective analysis across children below 18 years old diagnosed with VRTs in Lithuania between the years 2000 to 2015. The identified cases were then crosschecked with the Lithuanian Cancer Registry (a population-based epidemiology cancer registry) for the registration and survival status. A five year overall survival (OS 5y ) was calculated using Kaplan-Meier estimation method. Results . Forty-four children affected by VRTs were identified within the defined time frame. Nine of them (20.5%) were not reported to the Lithuanian Cancer Registry at the time of diagnosis. The OS 5y of the entire cohort was 55.8%. The cure rate did not improve over the analyzed time periods – 54.2% in 2000-2007 vs 49.4% in 2008-2015. The OS 5y differed significantly between registered (n=35) and unregistered (n=9) cohorts: 45.1% vs 100%, respectively (p=0.016). The tumor progression was responsible for treatment failure in 95% of cases. Conclusions. The OS 5y of all analyzed children affected by VRT was lower as compared to the other childhood cancers. The survival rate of the unregistered patients was significantly superior that mislead interpretation of treatment outcome. Meticulous registration of VRTs is crucial for correct evaluation of treatment outcome, especially across small countries with fewer numbers of cases.
Įvadas. Sąmonės sedacija (SS) ir bendroji endotrachėjinė anestezija (BETA) – anestezijos metodai, taikomi mechaninės trombektomijos (MTE) metu. Tikslių rekomendacijų dėl anestezijos metodo pasirinkimo MTE metu nėra. Retrospektyviniai tyrimai teigia, kad BETA yra susijusi su blogesnėmis pacientų išeitimis, tačiau naujuose klinikiniuose tyrimuose tokio skirtumo nestebima. Darbo tikslas buvo nustatyti anestezijos metodo įtaką mechaninės trombektomijos efektyvumui ir saugumui ligoniams, patyrusiems ūminį išeminį insultą. Tiriamieji ir tyrimo metodai. Į tyrimą įtraukti dviejuose Vilniaus centruose gydyti ūminį išeminį insultą patyrę ligoniai, kuriems buvo atlikta MTE. Ligoniai suskirstyti į 2 grupes pagal taikytą anestezijos metodą: bendroji endotrachėjinė anestezija (BETA) ir sąmonės sedacija (SS). Abiejose grupėse vertinti demografiniai, klinikiniai ir logistiniai rodikliai. Pirminiu vertinimo kriterijumi pasirinkta gera baigtis po 24 valandų. MTE saugumas vertintas pagal 7 parų mirštamumą ir simptominių intrasmegeninių kraujosruvų (sISK) dažnį. Rezultatai. Į tyrimą įtraukta 248 pacientai. 105 pacientams (42,3 %) taikyta BETA ir 143 (57,7 %) – SS. Pagal pradines charakteristikas abi grupės statistiškai nesiskyrė, išskyrus prieširdžių virpėjimo dažnį (55,9 % – SS vs 37,1 % – BETA grupėje, p = 0,003) ir intraveninės trombolizės taikymą iki MTE (66,4 % – SS grupėje ir 46,7 % – BETA grupėje, p = 0,003). Gera baigtis po 24 val. nustatyta 51,4 % (n = 54) ligonių – BETA grupėje ir 58,7 % (n = 84) ligonių – SS grupėje (p = 0,252). 7 parų mirštamumo sISK dažnis abiejose grupėse statistiškai reikšmingai nesiskyrė. Regresinė analizė parodė, kad geros baigties nepriklausomi prognoziniai veiksniai yra laikas nuo atvykimo į stacionarą iki rekanalizacijos ir sėkminga rekanalizacija. Išvados. Anestezijos tipas nėra reikšmingas mechaninės trombektomijos efektyvumo ir saugumo veiksnys ankstyvai pacientų baigčiai. Siekiant tiksliau įvertinti anestezijos reikšmę mechaninės trombektomijos baigčiai ir nustatyti procedūros baigties prognozinius veiksnius, reikalingi papildomi atsitiktinės atrankos tyrimai.
