The value of case reports in rare oncological scenarios: mixed method analysis of colorectal metastases from breast cancer
AbstractWith improved survival of cancer patients, we increasingly encounter infrequent metastatic locations. While for the common metastatic locations both prognostic information as well as evidence-based guidelines are available, for rare locations we have to rely on anecdotal case reports, the value of which is currently unknown. Therefore, we performed a systemic literature review and compare the results with a large national real-life cohort focussed on breast cancer patients with colorectal metastases. We performed a systematic literature search for breast cancer patients with colorectal metastases. Autopsy studies w...

CD44 in Bone Metastasis Development: A Key Player in the Fate Decisions of the Invading Cells?
AbstractA participant in key developmental processes, the adhesion glycoprotein CD44 is also expressed in several types of malignancies and can promote metastasis. In addition, the expression of CD44 isoforms in different types of cancer such as prostate and breast cancers may facilitate bone metastases by enhancing tumorigenicity, osteomimicry, cell migration, homing to bone, and anchorage within the bone specialized domains. Moreover, there is evidence that the CD44-ICD fragments in breast cancer cells may promote the cells ’ osteolytic nature. Yet the mechanisms by which CD44 and its downstream effectors promote the e...

Early biochemical outcomes following PSMA guided approach for bIoCHEmical relapse after prostatectomy-PSICHE trial (NCT05022914): preliminary results
AbstractPSICHE (NCT05022914) is a prospective trial to test a [68Ga]Ga- PSMA-11 PET/CT imaging tailored strategy. All evaluable patients had biochemical relapse after surgery and underwent centralized [68Ga]Ga-PSMA-11 PET/CT imaging. The treatment was performed according pre-defined criteria. Observation and re-staging at further PSA progression were proposed to patients with negative PSMA and previous postoperative RT. Prostate bed SRT was proposed to all patients with a negative staging or positive imaging within prostate bed. Stereotactic body radiotherapy (SBRT) to all sites of disease was used for all patients with pe...

Should EUS-FNA be considered also for the diagnosis of peripheral small pulmonary lesions?
AbstractGiven the high rate of small lung nodules detected during the oncological follow up for various cancers, in the era of personalize medicine, the histological diagnosis is of paramount importance. Usually, the small peripheral lung nodules are historically reached using a CT guided biopsy but this technique is characterized by an high rate of pneumothorax. Endoscopic procedures were referred only for central tumor that occluded the mains bronchi. In the last few years, the spreading of EBUS-TBNA, EUS-FNA and the navigational bronchoscopy systems has increase the use of these technique also for the diagnosis of small...

Repurposing fluphenazine to suppress melanoma brain, lung and bone metastasis by inducing G0/G1 cell cycle arrest and apoptosis and disrupting autophagic flux
AbstractBrain metastasis is the main cause of treatment failure and melanoma-related death. Inadequate concentrations of therapeutic drugs in the brain due to the blood-brain barrier (BBB) pose a major challenge in the treatment of brain metastasis. Antipsychotics can cross the BBB to reach the brain. Fluphenazine (FPZ) inhibits the survival of melanoma cells in vitro. However, its efficacy in suppressing the metastasis of melanoma, especially brain metastasis, remains unknown. Therefore, we explored whether fluphenazine (FPZ) can be repurposed for treating melanoma metastasis. A subcutaneous tumor model, and experimental ...

Brain metastases from hepatopancreatobiliary malignancies
AbstractWhile colorectal and gastroesophageal cancer represent the two gastrointestinal (GI) tumor entities with the highest incidence of brain metastatic (BM) disease, data on the clinical course of BM patients from hepatopancreatobiliary malignancies are rare. Patients with cholangiocarcinoma  (CCA), hepatocellular carcinoma (HCC), pancreatic ductal adenocarcinoma (PDAC) and gastroenteropancreatic neuroendocrine neoplasms (GEP NEN). Treated for BM between 1991 and 2017 at an academic care center were included. Brain metastases-free survival (BMFS) was defined as interval from first di agnosis until BM development. Ove...

Prostate and metastasis diffusion volume based on apparent diffusion coefficient as a prognostic factor in Hormone-na ïve prostate Cancer
In this study, to assess the utility of whole-body DWI (WB-DWI) as an imaging biomarker for metastatic hormone-na ïve prostate cancer (mHNPC), we evaluated tumor diffusion volume based on apparent diffusion coefficient (ADC) values. WB-DWI results obtained from 62 mHNPC patients were evaluated in this retrospective analysis. The association with castration resistant–free survival (CFS) was evaluated for both prostate and metastatic tumor diffusion volume (pDV and mDV, respectively) based on WB-DWI. The usefulness of pDV and mDV based on ADC values to predict CFS was also examined. During the follow-up period, 22 patient...

Belvarafenib penetrates the BBB and shows potent antitumor activity in a murine melanoma brain metastasis model
This study confirmed the brain penetration of belvarafenib, the antitumor activity on BRAF and NRAS mutant melanoma, and the efficacy on melanoma within the brain. Belvarafenib strongly suppressed melanoma in BRAF V600E mutant A375SM tumor-bearing mice. It also significantly inhibited tumor growth in NRAS mutant SK-MEL-30 and K1735 tumor-bearing mice and synergized to enhance the antitumor activity combined with cobimetinib or atezolizumab. Belvarafenib was penetrated at considerable levels into the brains of mice and rats following oral administration. The exposure of belvarafenib in the brain was similar to or higher tha...

International cooperation to fight cancer ’s late-stage presentation in low- and middle-income countries
AbstractCancer is becoming a massive public health burden in low- and middle-income countries (LMIC). 70% of all cancer deaths globally are attributed to LMIC while the incidence proportion is below 60%. The main reason for the higher mortality rate is “late-stage presentation” of patients with stage III or IV diseases when being diagnosed. Main reasons for this are limited (financial) resources, poor knowledge of health service provider about cancer, misbelieves and fear among patients as well as low health literacy rate. During the 1st Inter national Conference on Hospital Partnerships, conducted by the German Agency...

New perspectives in unresectable cholangiocarcinoma? Evaluation of chemosaturation with percutaneous hepatic perfusion as a palliative treatment option
AbstractCholangiocarcinoma (CCA) are the second most common primary liver tumors and carry a dismal prognosis. Chemosaturation with percutaneous hepatic perfusion (PHP) is a palliative, intra-arterial therapeutic approach that provides a high dose chemotherapy of the liver with reduced systemic exposure. Aim of this retrospective, monocentric study was to analyze PHP as a palliative treatment for unresectable CCA. Toxicity, adverse events and complications were classified using the Common Terminology Criteria for Adverse Events (CTCAE v5.0). Overall response rate (ORR) and disease control rate (DCR) were evaluated accordin...
