Primary choriocarcinoma of the ovary is rare. Furthermore, this tumor can arise from gestational tissue or pure germ cells of the ovary, with the latter resulting in non-gestational choriocarcinoma. While the clinical characteristics and histology of both tumor types are identical, differentiation of these tumors is necessary for effective treatment. One strategy for the differentiation of these tumors types is to assay for the presence of paternal DNA. Accordingly, in the present case, a patient with primary choriocarcinoma of the ovary with a non-gestational origin was confirmed by DNA analysis. The patient subsequently exhibited an excellent response to chemotherapy, and following surgery, achieved complete remission. A pathological analysis of surgical specimens further confirmed the absence of tumor.
PurposeMalignancy-related hypercalcemia (MRH) is associated with a dismal prognosis. The widespread use of bisphosphonates (BPs), availability of more effective drugs in cancer treatment, and improvement in supportive care might have attenuated its impact.Patients and MethodsTo assess overall survival (OS) of patients with MRH in a contemporary setting, we conducted a retrospective analysis of 306 patients with solid cancer hospitalized for symptomatic hypercalcemia. A multivariable Cox proportional hazards regression model was performed to evaluate possible prognostic factors associated with MRH.ResultsAll patients had serum ionized calcium > 5.5 mg/dL or total Ca > 10.5 mg/dL. Median age was 57 years, and the majority had squamous cell carcinoma (62%) and Eastern Cooperative Oncology Group performance status > 1 (96%). Head and neck was the most frequent primary site (28%). Forty-five percent had no previous chemotherapy (CT), and subsequent CT was administered to 32%. Eighty-three percent received BP with no survival gain. Median OS was 40 (95% CI, 33 to 47) days. Patients with a performance status > 2, altered mental status, C-reactive protein > 30 mg/L, albumin < 2.5 g/dL, or body mass index < 18 kg/m2 had significantly poorer survival in a univariable analysis, and longer OS was related to treatment-naive patients, subsequent CT, and breast primary site. In the multivariable analysis, subsequent CT led to a median OS improvement of 144 versus 25 days (hazard ratio, 0.24; 95% CI, 0.14 to 0.40; P < .001).ConclusionIn a contemporary setting, MRH remains a marker of poor prognosis. Patients treated with CT had better survival, which suggests that appropriate treatment of selected patients might alter the course of this syndrome.
PurposeAlthough patients with incurable disease and Eastern Cooperative Oncology Group performance status (ECOG-PS ≥ 2) are underrepresented in clinical trials, they are frequently offered palliative chemotherapy (pCT) in daily clinical practice in order to improve symptoms and quality of life. In this case-control retrospective analysis, our goal was to identify factors associated with poorer survival and lack of benefit of pCT in this population.Patients and methodsWe evaluated 2,514 patients who died between August 2011 and July 2012 in an academic cancer care institution and its hospice. A total of 301 patients with solid tumours and ECOG-PS ≥ 2 at prescription of pCT were selected for this case-control retrospective analysis. Cases were defined as patients who survived less than 90 days after the first cycle of first line pCT, and controls were those who had a longer survival.Results142 cases and 159 controls were included. Cases were more likely to experience grade ≥ 3 toxicity (43% versus 28%; p = 0.005), die of toxicity (16% versus 6%; p < 0.001) and not be offered best supportive care (BSC) only (47% versus 71%; p < 0.001). Median overall survival was 204 among controls and 34 days in cases (hazard ratio = 0.177; 95%, confidence interval = 0.015–0.033, p < 0.001). Logistic regression analysis identified ECOG-PS > 2 (odds ratio (OR) = 2.3, p = 0.044) and serum creatinine (sCr) > 1 mg/dL (OR = 11.2, p < 0.001) as independent predictors of 90-day mortality.ConclusionsThe independent predictors of short survival (less than 3 months) after initiation of pCT in this population were ECOG-PS > 2 and elevated sCr. Therefore, patient selection is crucial, as pCT may be deleterious in ECOG-PS ≥ 2 pts.
Background: Trastuzumab improves the survival of patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer (BC). The incidence and long-term impact of trastuzumab-related cardiotoxicity in the community setting is of great clinical importance. Material and Methods: Patients with HER2-positive BC treated with (neo)adjuvant trastuzumab were retrospectively evaluated. Cardiotoxicity was defined as cardiac death or absolute decrease in left ventricular ejection fraction of at least 10% to a value less than 50%, or symptomatic heart failure. Results: We evaluated 237 patients: median age 53 years (range 27-83 years). 40.5% of these patients had received neoadjuvant and 59.5% adjuvant chemotherapy. The majority (83.9%) were treated with an anthracycline-based regimen. Median exposure to trastuzumab was 8 months (range 2-12 months). Cardiotoxicity was diagnosed in 20.2%, but symptoms only occurred in 3.8%. 41.6% recovered cardiac function. None of the risk factors were associated with cardiotoxicity. Conclusion: The incidence of trastuzumab-related cardiotoxicity found in this study was slightly higher than those reported in randomized clinical trials. Nevertheless, most patients were asymptomatic. We describe the cardiac outcomes of a non-selected population, which possibly reflects those found in the ‘real world'. The risks versus benefits of trastuzumab use remain in favor of treatment, but cardiotoxicity should be monitored.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
