Cyclooxygenase-2 Expression Determines Neoangiogenesis in Gallbladder Carcinomas

Neo-angiogenesis may have an important role in the poor prognosis of gallbladder carcinoma. An enhanced expression of COX-2 was found in precancerous lesions and in gallbladder carcinoma, likely to be involved in carcinogenesis as well as in angiogenesis. To study the relationships between the COX-2 expression and degree of vascularization, as well as to evaluate their role in the prognosis of patients with gallbladder carcinoma. 27 cases of gallbladder adenocarcinoma were included, classified grading I-III according the WHO classification. The COX-2 and endothelial antigen CD105 expressions were assessed immunohistochemically. COX-2 expression was evaluated according to the percentage and staining intensity of positive cells into "COX-2 positive" and "COX-2 negative" groups. In order to assess tumor microvessel density (MVD), CD105 positively stained microvessels were counted for each specimen in predominantly vascular areas (hot spots) at 200 x magnification. The MVD ranged from 9 to 46 microvessels/field. 15 tumors belonged to the hypervascular group (MVD > or = 25) and 12 to the hypovascular group. There were 16 (59.2%) COX-2 positive cases. There was difference in the degree of angiogenesis between COX-2 positive vs. COX-2 negative group: 11 (68.8%) out of 16 "COX-2 positive" tumors were hypervascular, in comparison with just 4 (36.4%) of "COX-2 negative" tumors. Our data show that the MVD corresponds to the COX-2 overexpression in gallbladder carcinomas. Augmented tumor neovascularization induced by COX-2 might be responsible for the poor prognosis in gallbladder carcinoma patients.

BACKGROUND: Gallbladder carcinoma presents a dismal prognosis. Choice treatment is surgical resection that is associated a high levels of both morbidity and mortality. Best knowledgement of prognostic factors may result a better selection of patients either for surgical or multimodal treatment. AIM: To evaluate tecidual immunoexpression of P53, E-cadherin, Cox-2, and EGFR proteins and to correlate these findings with resected gallbladder adenocarcinoma survival. METHODS: Clinical, laboratorial, surgical, and anatomopathological reports of a series of gallbladder adenocarcinoma patients were collected by individualized questionary. Total sample was 42 patients. Median of age was 72 years (35-87). There were seven men and 35 women. Lesion distribuition in according TNM state was the following: T1 (n=2), T2 (n=5), T3 (n=31), T4 (n=4). Twenty-three patients underwent radical resection (R0), while 19 palliative surgery (R1-R2). A block of tissue microarray with neoplasic tissue of each patient was confected. It was performed evaluation of P53, E-Caderine, COX-2, and EGFR proteins imunoexpression. These findings were correlated with overall survival. RESULTS: Five-year survival was 28%. The median of global survival was eight months. Only immunoexpression of EGFR protein was considered independent variable at multivariated analysis. CONCLUSION: Final prognosis was influenced by over-expression of EGFR protein in tumoral tissue.

Abstract Follicular lymphoma has considerable clinical heterogeneity, and there is a need for easily quantifiable prognostic biomarkers. Microvessel density has been shown to be a useful prognostic factor based on numerical assessment of vessel numbers within histologic sections in some studies, but assessment of tumor neovascularization through angiogenic sprouting may be more relevant. We therefore examined the smallest vessels, single-staining structures measuring less than 30 μm2 in area, seen within histologic sections, and confirmed that they were neovascular angiogenic sprouts using extended focal imaging. Tissue microarrays composing diagnostic biopsies from patients at the extremes of survival of follicular lymphoma were analyzed with respect to numbers of these sprouts. This analysis revealed higher angiogenic activity in the poor prognostic group and demonstrated an association between increased sprouting and elevated numbers of infiltrating CD163+ macrophages within the immediate microenvironment surrounding the neovascular sprout.

Intratumor heterogeneity is partly responsible for the poor prognosis of glioblastoma (GBM) patients. In this study, we aimed to assess the effect of different heterogeneous subregions of GBM on overall survival (OS) stratification. A total of 105 GBM patients were retrospectively enrolled and divided into long-term and short-term OS groups. Four MRI sequences, including contrast-enhanced T1-weighted imaging (T1C), T1, T2, and FLAIR, were collected for each patient. Then, 4 heterogeneous subregions, i.e. the region of entire abnormality (rEA), the regions of contrast-enhanced tumor (rCET), necrosis (rNec) and edema/non-contrast-enhanced tumor (rE/nCET), were manually drawn from the 4 MRI sequences. For each subregion, 50 radiomics features were extracted. The stratification performance of 4 heterogeneous subregions, as well as the performances of 4 MRI sequences, was evaluated both alone and in combination. Our results showed that rEA was superior in stratifying long-and short-term OS. For the 4 MRI sequences used in this study, the FLAIR sequence demonstrated the best performance of survival stratification based on the manual delineation of heterogeneous subregions. Our results suggest that heterogeneous subregions of GBMs contain different prognostic information, which should be considered when investigating survival stratification in patients with GBM.

First Complete Remission

AbstractThis is a retrospective study comparing the effectiveness of umbilical cord blood transplantation (UCBT) and chemotherapy for patients in the first complete remission period for acute myeloid leukemia with KMT2A-MLLT3 rearrangements. A total of 22 patients were included, all of whom achieved first complete remission (CR1) through 1–2 rounds of induction chemotherapy, excluding patients with an early relapse. Twelve patients were treated with UCBT, and 10 patients were treated with chemotherapy after 2 to 4 courses of consolidation therapy. The 3-year overall survival (OS) of the UCBT group was 71.3% (95% CI, 34.4–89.8%), and that of the chemotherapy group was 10% (95% CI, 5.89–37.3%). The OS of the UCBT group was significantly higher than that of the chemotherapy group (P = 0.003). The disease-free survival (DFS) of the UCBT group was 60.8% (95% CI, 25.0–83.6%), which was significantly higher than the 10% (95% CI, 5.72–35.8%) of the chemotherapy group (P = 0.003). The relapse rate of the UCBT group was 23.6% (95% CI, 0–46.8%), and that of the chemotherapy group was 85.4% (95% CI, 35.8–98.4%), which was significantly higher than that of the UCBT group (P < 0.001). The non-relapse mortality (NRM) rate in the UCBT group was 19.8% (95% CI, 0–41.3%), and that in the chemotherapy group was 0.0%. The NRM rate in the UCBT group was higher than that in the chemotherapy group, but there was no significant difference between the two groups (P = 0.272). Two patients in the UCBT group relapsed, two died of acute and chronic GVHD, and one patient developed chronic GVHD 140 days after UCBT and is still alive, so the GVHD-free/relapse-free survival (GRFS) was 50% (95% CI, 17.2–76.1%). AML patients with KMT2A-MLLT3 rearrangements who receive chemotherapy as their consolidation therapy after CR1 have a very poor prognosis. UCBT can overcome the poor prognosis and significantly improve survival, and the GRFS for these patients is very good. We suggest that UCBT is a better choice than chemotherapy for KMT2A-MLLT3 patients.

Abstract Background Pancreatic cancer (PC) is a devastating disease that has a poor prognosis and a total 5-year survival rate of around 5%. The poor prognosis of PC is due in part to a lack of suitable biomarkers that can allow early diagnosis. The lysophospholipase autotaxin (ATX) and its product lysophosphatidic acid (LPA) play an essential role in disease progression in PC patients and are associated with increased morbidity in several types of cancer. In this study, we evaluated both the potential role of serum LPA and ATX as diagnostic markers in PC and their prognostic value for PC either alone or in combination with CA19-9. Methods ATX, LPA and CA19-9 levels were evaluated using ELISA of serum obtained from PC patients (n = 114) healthy volunteers (HVs: n = 120) and patients with benign pancreatic diseases (BPDs: n = 94). Results Serum levels of ATX, LPA and CA19-9 in PC patients were substantially higher than that for BPD patients or HVs (p < 0.001). The sensitivity of LPA in early phase PC was 91.74% and the specificity of ATX was 80%. The levels of ATX, LPA and CA19-9 were all substantially higher for early stage PC patients compared to levels in serum from BPD patients and HVs. The diagnostic efficacy of CA19-9 for PC was significantly enhanced by the addition of ATX and LPA (p = 0.0012). Conclusion Measurement of LPA and ATX levels together with CA19-9 levels can be used for early detection of PC and diagnosis of PC in general.

e23500 Background: Dedifferentiated chondrosarcoma (DCS) is a rare and aggressive malignancy with a poor prognosis. The purpose of this investigation was to assess the clinicopathological features and outcomes of DCS patients treated at a single institution. Methods: This study was a retrospective review over a consecutive twenty-year period. Data including treatment details and outcomes were recorded. Results: A total of 16 cases from 2000 to 2018 were reviewed. The median age was 62 years (IQR, 52-69 years) and the majority of DCS arose in the femur (50%, n = 8) and pelvis (25%, n = 4). Fourteen (88%) cases received limb salvage/wide margin resection (n = 13) or intralesional surgery (n = 1). For all DCS, the median estimated overall survival (OS) was 46 months (95% CI, 1-90 months) with both a five and ten-year survival probability of 32%. On Kaplan-Meier analysis there was no difference between operative versus nonoperative management (p = 0.747), surgery alone versus surgery/chemotherapy (p = 0.265), nor surgery alone versus surgery/chemotherapy/radiation (p = 0.698). Conclusions: Our findings confirm the poor prognosis of DCS patients, though with a five-year estimate of 32%, higher than previous literature. Together with existing literature, our data may enable future strategic recommendation of DCS patients.
