Circulating microRNA biomarkers for metastatic disease in neuroblastoma patients
2018
In this study, the circulating miRNome from diagnostic neuroblastoma serum was assessed for identification of noninvasive biomarkers with potential in monitoring metastatic disease. After determining the circulating neuroblastoma miRNome, 743 miRNAs were screened in 2 independent cohorts of 131 and 54 patients. Evaluation of serum miRNA variance in a model testing for tumor stage, MYCN status, age at diagnosis, and overall survival revealed tumor stage as the most significant factor impacting miRNA abundance in neuroblastoma serum. Differential abundance analysis between patients with metastatic and localized disease revealed 9 miRNAs strongly associated with metastatic stage 4 disease in b…
Cytokeratin-18 fragments predict treatment response and overall survival in gastric cancer in a randomized controlled trial
2018
Background:Gastric cancer is common malignancy and exhibits a poor prognosis. At the time of diagnosis, the majority of patients present with metastatic disease which precludes curative treatment. Non-invasive biomarkers which discriminate early from advanced stages or predict the response to treatment are urgently required. This study explored the cytokeratin-18 fragment M30 and full-length cytokeratin-18 M65 in predicting treatment response and survival in a randomized, placebo-controlled trial of advanced gastric cancer.Methods:Patients enrolled in the SUN-CASE study received sunitinib or placebo as an adjunct to standard therapy with leucovorin (Ca-folinate), 5-fluorouracil, and irinote…
Second line therapy with axitinib after only prior sunitinib in metastatic renal cell cancer: Italian multicenter real world SAX study final results
2019
Abstract Background This multi-institutional retrospective real life study was conducted in 22 Italian Oncology Centers and evaluated the role of Axitinib in second line treatment in not selected mRCC patients. Methods 148 mRCC patients were evaluated. According to Heng score 15.5%, 60.1% and 24.4% of patients were at poor risk, intermediate and favorable risk, respectively. Results PFS, OS, DCR and ORR were 7.14 months, 15.5 months, 70.6% and 16.6%, respectively. The duration of prior sunitinib treatment correlated with a longer significant mPFS, 8.8 vs 6.3 months, respectively. Axitinib therapy was safe, without grade 4 adverse events. The most frequent toxicities of all grades were: fati…
A Phase I Study of Cisplatinum plus 5-Fluorouracil in Modulation with Citrovorum Factor in Metastatic Colorectal Carcinoma
1991
A phase I study of 5-fluorouracil 600 mg/m2/week and folinic acid 500 mg/m2/week on day 1 and cisplatin administered weekly on day 2 was carried out on 30 patients with metastatic colorectal carcinoma of which 20 patients were pretreated with 5-fluorouracil. The first group of patients received cisplatin at the dose of 5 mg/m2/week. Cisplatin was then escalated to 10, 15, 20, 25, 30, and 35 mg/m2/week for subsequent groups of patients. Gastrointestinal side-effects were the dose-limiting toxicity. A therapy related death was seen at the dose of 35 mg/m2/week of cisplatin. The maximally tolerated dose of cisplatin in combination with 5-fluorouracil and citrovorum factor is 20 mg/m2/week. The…
High proliferation rate and TNM stage but not histomorphological subtype are independent prognostic markers for overall survival in papillary renal c…
2018
Papillary renal cell carcinoma (PRCC) is currently divided in 2 subtypes. We reviewed a large cohort of PRCC and correlated subtype, morphological features and diagnostic marker expression with overall survival (OS) to uncover differences between the 2 subtypes. Three hundred seventy-six renal tumors initially diagnosed as PRCC with clinical and survival data were collected from the participating centers. Two hundred forty-six tumors were classified as PRCC1 (65.4%) and 130 as PRCC2 (34.6%) and graded according to the 2016 World Health Organization/International Society of Urological Pathology grading system. Morphological features (abundant cytoplasm, necrosis, fibrous stroma, foamy macrop…
Metastatic Anterior Chamber Non-Hodgkin Lymphoma in a Patient With Acquired Immunodeficiency Syndrome
1997
Purpose To alert ophthalmologists to the possibility of metastatic anterior chamber intraocular non-Hodgkin lymphoma in patients with acquired immunodeficiency syndrome (AIDS). Methods We examined a 19-year-old man with AIDS who had an anterior uveitis with pseudohypopyon and a history of 2 months of malaise. A specimen of the lesion was obtained with a 25-gauge needle for pathologic examination. RESULTS: Systemic exploration showed hepatomegaly. Abdominal computed tomography showed multiple lesions in the liver and spleen. Fine-needle aspiration disclosed a high-grade non-Hodgkin lymphoma. The result of a fine-needle aspiration obtained from a lesion in the anterior chamber was consistent …
Biweekly oxaliplatin combined with oral capecitabine (OXXEL regimen) as first-line treatment of metastatic colorectal cancer patients: a Southern Ita…
2005
Oxaliplatin 100 mg/m(2) iv on day 1, and capecitabine 1,000 mg/m(2) orally bid from day 1 (evening) to day 11 (morning) were administered every 2 weeks (OXXEL regimen) to 38 patients as first-line treatment for metastatic colorectal carcinoma. A total of 318 cycles were administered, with a median of 8 (range, 4-12) cycles per patient. Response rate (RR) was 45% (95% confidence interval (CI), 29%-62%), with 7 complete responses and 10 partial responses; furthermore, 12 patients showed a stable disease, so that a disease control was achieved in 29 (76%) patients. RR was greater among patients with performance status 0 (52%), without weight loss (52%), younger than 65 years (50%), and previou…
Predictive chromosomal clusters of synchronous and metachronous brain metastases in clear cell renal cell carcinoma
2014
Synchronous (early) and metachronous (late) brain metastasis (BM) events of sporadic clear cell renal cell carcinoma (ccRCC) (n = 148) were retrospectively analyzed using comparative genomic hybridization (CGH). Using oncogenetic tree models and cluster analyses, chromosomal imbalances related to recurrence-free survival until BM (RFS-BM) were analyzed. Losses at 9p and 9q appeared to be hallmarks of metachronous BM events, whereas an absence of detectable chromosomal changes at 3p was often associated with synchronous BM events. Correspondingly, k-means clustering showed that cluster 1 cases generally exhibited low copy number chromosomal changes that did not involve 3p. Cluster 2 cases ha…
Expression of nm23 in gastric carcinoma: association with tumor progression and poor prognosis.
1998
BACKGROUND Expression of nm23 has been shown to be inversely correlated with the metastatic potential of several human cancers. In the current study, the expression and prognostic impact of nm23 was immunohistochemically studied in 413 curatively resected gastric carcinomas. METHODS Tumor sections of the 413 gastric carcinomas were stained with a polyclonal antibody that was raised against the nm23-H1/NDP kinase A, which is identical to the nm23-H1 gene product. RESULTS Expression of nm23 was detected in 84.5% (n = 349) of all tumors, in the majority of cases (71.2%) causing a homogeneous staining reaction in more than 75% of tumor cells. Expression of nm23 was positively correlated with th…
Increased expression of transketolase-like-1 in papillary thyroid carcinomas smaller than 1.5 cm in diameter is associated with lymph-node metastases.
2008
BACKGROUND. Patients with small papillary thyroid carcinoma (PTC) may have a high incidence of regional lymph-node (LN) metastases at presentation, and these are considered to be an independent risk factor for tumor recurrence. A mutated transketolase transcript (TKTL1) has been found up-regulated in different human malignancies, and strong TKTL1 protein expression has been associated with aggressiveness and poor patient survival in several epithelial cancers. METHODS. TKTL1 protein expression was analyzed in 256 consecutive cases of PTCs ≤1.5 cm by immunohistochemistry with a specific anti-TKTL1 antibody. RNA analysis was performed by real-time polymerase chain reaction (PCR) in all cases …
