Lebermetastasen kolorektaler Karzinome - wie oft kann man operieren?

2007

Recurrent liver metastases of colorectal carcinoma are frequent. The repeat hepatectomy is superior to other therapeutic options. In about 20 % of patients with recurrent liver metastases a complete resection (R 0) is possible. The morbidity of repeat hepatectomy is similar to that of first hepatectomy. The 5-year survival rate after repeat hepatectomy ranges between 30 and 40 %. Often in the follow-up additional operations become necessary for extrahepatic recurrencies. For determination of the optimal therapy an interdisciplinary approach must be chosen.

WWOX, a Chromosomal Fragile Site Gene and its Role in Cancer

2006

Allelic imbalances affecting the long arm of chromosome 16 have been extensively reported in the literature as common abnormalities observed in various carcinoma types, As a result of loss of heterozygosity (LOH) studies in breast cancer, we delimited a genomic area within chromosome 16 that demonstrated the highest frequency of abnormalities. This led us to the identification and cloning of WWOX, a candidate tumor suppressor gene (TSG) that spans a fragile region of DNA located at 16q23.3-24.1 (FRA16D: the second most active common chromosomal fragile site in the human genome). This gene encodes a protein that contains two WW domains responsible of protein-protein interactions and a short-…

Health-related quality of life (HRQOL) in patients (pts) with advanced gastric cancer/gastroesophageal junction cancer (GC/GEJC) or esophageal adenoc…

2021

4066 Background: CheckMate 649 (NCT02872116) is a randomized, open label phase 3 study in first line (1L) GC/GEJC/EAC. Prespecified interim results showed statistically significant improvement in overall survival (OS) and progression-free survival (PFS) for N+C vs C in all randomized pts and pts whose tumors expressed programmed death-ligand 1 combined positive score (CPS) ≥ 5. We present interim HRQOL results for CPS ≥ 5 pts, included as exploratory in the study. Methods: HRQOL was assessed using EQ-5D-3L (EQ-5D) and Functional Assessment of Cancer Therapy–Gastric Cancer (FACT-Ga). Assessments were performed at baseline (BL), every 6 weeks during treatment, and during follow-up. Change fr…

Multicenter analysis of serum tumor markers, treatment patterns, and relapse in patients with testicular cancer in clinical stage IS.

2020

5052 Background: Testicular germ cell tumors (TGCT) in clinical stage I (CSI) are tumors confined to the testis without evidence of metastasis. Around 50% of all TGCT patients present with elevated serum tumor markers (TM) such as alpha-feto protein (AFP), beta-humanochoriongonadotropin (ß-HCG) and lactate-dehydrogenase (LDH). After ablatio testis, TMs usually return to normal according to half-life kinetics, however, in clinical stage IS (CSIS) TMs remain elevated or increase after surgery. Follow-up data on CSIS is scarce and our study aims to assess clinical characteristics and oncologic outcomes in a large TGCT cohort. Methods: In this multicenter study we collected data from 5 tertiar…

Use of bone scintigraphy in the early diagnosis of bisphosphonate related osteonecrosis of the jaw. Case report and review of the literature

2018

The main aim of the present report is to show the potential utility of bone scintigraphy for the diagnosis of jaw osteonecrosis. We report the history of a 62-year-old woman underwent breast cancer surgery in 2010. Moreover, patient received postoperative radiotherapy and chemotherapy. Intravenous bisphosphonates were also added to the treatment strategy to reduce the risk of bone metastasis. However, a hypermetabolic focus on left hemimandible was evidenced with a bone scintigraphy during follow up. After a careful study, the diagnosis of Bisphosphonate Related Ostneonecrosis of the Jaw (BRONJ) was carried out. This case highlights that bone scintigraphy may be extremely helpful for the ea…

Relapsed and/or Refractory Mantle Cell Lymphoma: What Role for Temsirolimus?

2012

Mantle Cell Lymphoma (MCL) is associated with a dismal prognosis. Recently, along with the improved understanding of the pathophysiology of this disease, new first line regimens have been established and in addition novel treatment options have entered the clinical arena. In consequence, prognosis of the disease has fortunately improved. We here focus on the rationale, current clinical knowledge and future concepts of Temsirolimus, an inhibitor of mTOR, in the treatment of MCL. At this time this drug has been shown to be effective as single agent for relapsed disease and early combination data show promising results. In addition, with a brief outline of other treatment options, we aim to g…

Roles of p53, NF-κB and the androgen receptor in controlling NGAL expression in prostate cancer cell lines

2018

Neutrophil gelatinase-associated lipocalin (NGAL a.k.a lipocalin 2, lnc2) is a secreted protein which can form a complex with matrix metalloproteinase-9 (MMP9). This MMP9/NGAL complex has been associated with metastasis. MMP9 and NGAL are detected in the urine of patients afflicted with many different types of cancer, including prostate cancer. The effects of p53, NF-κB and the androgen receptor (AR) on the expression of NGAL was examined in four prostate cancer cell lines. Prostate cancer cell lines that are AR negative and expressed either mutant or no p53 (DU145 and PC3) displayed higher levels of NGAL expression compared to the prostate cancer cell lines (LNCaP and 22Rv-1) which are AR …

Centrosome amplification induced by hydroxyurea leads to aneuploidy in pRB deficient human and mouse fibroblasts.

2006

Alterations in the number and/or morphology of centrosomes are frequently observed in human tumours. However, it is still debated if a direct link between supernumerary centrosomes and tumorigenesis exists and if centrosome amplification could directly cause aneuploidy. Here, we report that hydroxyurea treatment induced centrosome amplification in both human fibroblasts expressing the HPV16 -E6-E7 oncoproteins, which act principally by targeting p53 and pRB, respectively, and in conditional pRB deficient mouse fibroblasts. Following hydroxyurea removal both normal and p53 deficient human fibroblasts arrested. On the contrary pRB deficient fibroblasts entered the cell cycle generating aneupl…
