Introduction: Controlled randomized trials, molecular analytics, and guideline recommendations have so far been irreplaceable tools to ensure appropriate treatment and decision-making for physicians and patients. Individual patient models are increasingly complementing these methods, particularly in the case of advanced cancers, rare cancers, and cancers of unknown primary (CUP), as in these cases comprehensive clinical evidence is unavailable, often resulting in poor treatment success, even after stratification.

Case Presentation: Here we report a 53-year-old patient with CUP with axillary lymph node metastases for whom patient-derived 3D (PD3D) tumor organoids successfully guided personalized treatment.

In 2007, the ASSO-LM1 trial, a multicenter prospective study, was initiated to investigate the resectability (R0) rate following preoperative combination therapy with XELOX and bevacizumab in patients with potentially resectable colorectal liver metastases. Six cycles of systemic therapy were administered preoperatively, although the sixth cycle did not include bevacizumab, resulting in 5 weeks between the last bevacizumab dose and surgery. Treatment with bevacizumab plus XELOX was restarted for another six cycles postoperatively.

Biliary tract cancers are rare cancers with poor prognosis due to a lack of therapeutic options, especially after the failure of first-line systemic treatment. Targeted treatments for this clinical situation are promising and have entered clinical practice. We aimed to describe the overall survival of matched targeted treatment after first-line treatment in patients with biliary tract cancers in an Austrian real-world multicenter cohort.

Introduction: Survival of patients suffering from metastatic colorectal cancer (mCRC) has increased over the last decades. These benefits appear to be restricted to patients aged 50 and above. However, among the population aged <50, colorectal cancer incidence and mortality rates are significantly rising.

Background: Twenty percent of colorectal cancer liver metastases (CLMs) are initially resectable with a 5-year survival rate of 25%-40%. Perioperative folinic acid, 5-fluorouracil, oxaliplatin (FOLFOX) increases progression-free survival (PFS). In advanced disease, the addition of targeting therapies results in an overall survival (OS) advantage.

Myelodysplastic/myeloproliferative neoplasm with neutrophilia (MDS/MPN-N; previously referred to as atypical chronic myeloid leukemia) is a type of myelodysplastic syndrome/myeloproliferative neoplasm. A molecular genetic precondition for diagnosis is negativity; further diagnostic criteria include clinicopathological assessments, such as peripheral blood leukocyte counts, the number of neutrophils and their precursors, and the presence of dysgranulopoiesis. The present case report highlights the importance of differential diagnoses with a stringent diagnostic workup according to the 5th Edition of the World Health Organization Classification of Hematolymphoid Tumors.

Metastatic BRAF mutated colorectal cancer is associated with poor overall survival and modest effectiveness to standard therapies. Furthermore, survival is influenced by the microsatellite status. Patients with microsatellite-stable and BRAF mutated colorectal cancer have the worst prognosis under the wide range of genetic subgroups in colorectal cancer.

Aflibercept plus FOLFIRI prolongs overall survival (OS) in patients with metastatic colorectal cancer after the failure of oxaliplatin-containing therapy. QoLiTrap prospectively evaluated the quality of life (QoL) and effectiveness of this regimen in daily clinical practice, according to RAS status, sex, and prior targeted therapy, especially epidermal growth factor receptor inhibitors (EGFR-I). The primary endpoint was the percentage of patients whose EORTC QLQ-C30 global health status (GHS) improved or reduced by <5% from baseline during the first 12 weeks of therapy.

Article Synopsis
  • A phase 3 trial evaluated the effectiveness of extending adjuvant aromatase inhibitor therapy (anastrozole) from 2 to 5 additional years in postmenopausal women with hormone-receptor-positive breast cancer after 5 years of prior treatment.
  • The study found no significant difference in disease-free survival between the two duration groups, with a similar number of disease progression or death cases in both.
  • However, the 5-year group had a higher risk of clinical bone fractures compared to the 2-year group, indicating that longer hormone therapy may not be beneficial and could pose additional risks.

In older patients with chronic myelomonocytic leukaemia (CMML) and limited life expectancy due to age and or comorbidities, it is particularly important to consider the risk of transformation for individualised treatment decisions. There is limited information on potential differences between younger and older CMML patients regarding the cumulative risk of transformation as well as haematological, molecular and biologic characteristics. We analysed data from the Austrian Biodatabase for CMML (ABCMML) to compare these parameters in 518 CMML patients.

Current National Comprehensive Cancer Network (NCCN) and European Society of Medical Oncology (ESMO) guidelines recommend regorafenib or trifluridine/tipiracil (TAS-102) for the third-line therapy of metastatic colorectal cancer (mCRC). In this analysis, we evaluated hospitalizations during regorafenib or TAS-102 treatment and the impact of hospitalizations on overall survival (OS). This retrospective analysis was based on unselected, consecutive mCRC patients treated with regorafenib and/or TAS-102 at the tertiary cancer centers in Salzburg and Wels-Grieskirchen, Austria.

The goal of current management of patients with chronic phase chronic myeloid leukemia (CML) is to reach treatment-free remission with sustained deep molecular remission (DMR) being the prerequisite therefor. Second-generation tyrosine kinase inhibitors can induce deeper and faster remission than imatinib, but are often associated with severe adverse events (AEs). The combination of pegylated interferon (IFN) with imatinib was shown to induce higher molecular remissions than imatinib alone in two studies.

Article Synopsis
  • Cancer treatments can negatively impact physical health and quality of life, with exercise emerging as a potential remedy that requires more research.
  • The ABCSG C07-EXERCISE study looked at a year-long exercise program for colorectal cancer patients post-chemotherapy and tracked their quality of life using standardized questionnaires.
  • Results showed significant improvements in social functioning and moderate gains in other areas like pain and financial impact, suggesting structured exercise could enhance quality of life for cancer survivors, but more extensive studies are needed to confirm these findings.

Patients with a myeloproliferative neoplasm (MPN) sometimes show a chronic myelomonocytic leukemia (CMML)-like phenotype but, according to the 2016 WHO classification, a documented history of an MPN excludes the diagnosis of CMML. Forty-one patients with an MPN (35 polycythemia vera (PV), 5 primary myelofibrosis, 1 essential thrombocythemia) and a CMML-like phenotype (MPN/CMML) were comprehensively characterized regarding clinical, hematologic, biologic and molecular features. The white blood cell counts in MPN/CMML patients were not different from CMML patients and PV patients.

Tumors have evolved mechanisms to escape anti-tumor immunosurveillance. They limit humoral and cellular immune activities in the stroma and render tumors resistant to immunotherapy. Sensitizing tumor cells to immune attack is an important strategy to revert immunosuppression.
