Background: 5-Fluorouracil (FU) is one of the most commonly used cytostatic drugs in the systemic treatment of cancer. Treatment with FU may cause severe or life-threatening side effects and the treatment-related mortality rate is 0.2–1.0%. Summary: Among other risk factors associated with increased toxicity, a genetic deficiency in dihydropyrimidine dehydrogenase (DPD), an enzyme responsible for the metabolism of FU, is well known. This is due to variants in the DPD gene (DPYD). Up to 9% of European patients carry a DPD gene variant that decreases enzyme activity, and DPD is completely lacking in approximately 0.5% of patients. Here we describe the clinical and genetic background and summarize recommendations for the genetic testing and tailoring of treatment with 5-FU derivatives. The statement was developed as a consensus statement organized by the German Society for Hematology and Medical Oncology in cooperation with 13 medical associations from Austria, Germany, and Switzerland. Key Messages: (i) Patients should be tested for the 4 most common genetic DPYD variants before treatment with drugs containing FU. (ii) Testing forms the basis for a differentiated, risk-adapted algorithm with recommendations for treatment with FU-containing drugs. (iii) Testing may optionally be supplemented by therapeutic drug monitoring. [ABSTRACT FROM AUTHOR]

Introduction: Penile metastases (PMs) are a rare clinical presentation mainly related to advanced stages of disease. Considering the low incidence, an optimal treatment approach has not yet been defined; surgery, chemotherapy, and radiotherapy (RT) are different options used in the vast majority with palliative intent. The advances in modern RT can represent an innovative tool in PM management and a curative option. This paper aimed to report the case of a PM patient treated with stereotactic body radiotherapy (SBRT) and perform a systematic literature review of current evidence on the RT approach to PM. Case Presentation: We reported the case of an 80-year-old patient with PM from primary bladder cancer. Following the surgical approach for the primary tumor, evidence of PM was shown, and the patient was admitted to SBRT treatment on PM after an adjuvant RT course on the pelvis. A 25 Gy in 5-fraction SBRT treatment was performed, and a complete clinical response was shown at the first follow-up. A PubMed/MEDLINE and Embase systematic review was carried out. The search strategy terms were [("penile metastasis"/exp OR "penile metastasis" OR (penile AND ("metastasis"/exp OR metastasis))) AND ("radiotherapy"/exp OR radiotherapy)] and only original articles up to October 24, 2023 were considered. Conclusion: A total of 174 studies were obtained using the previously mentioned search strategy, and the analysis was performed on 15 papers obtained following the complete selection process. All reported evidence was focused on the palliative approach of PM, showing good results in terms of symptom control. The potential role of modern RT in the management of PM has yet to be defined. The reported case showed the feasibility and the clinical impact of SBRT in PM treatment. [ABSTRACT FROM AUTHOR]

In the context of the COVID-19 pandemic, there has been a scarcity of resources with various effects on the care of cancer patients. This paper provides an English summary of a German guideline on prioritization and resource allocation for colorectal and pancreatic cancer in the context of the pandemic. Based on a selective literature review as well as empirical and ethical analyses, the research team of the CancerCOVID Consortium drafted recommendations for prioritizing diagnostic and treatment measures for both entities. The final version of the guideline received consent from the executive boards of nine societies of the Association of Scientific Medical Societies in Germany (AWMF), 20 further professional organizations and 22 other experts from various disciplines as well as patient representatives. The guiding principle for the prioritization of decisions is the minimization of harm. Prioritization decisions to fulfill this overall goal should be guided by (1) the urgency relevant to avoid or reduce harm, (2) the likelihood of success of the diagnostic or therapeutic measure advised, and (3) the availability of alternative treatment options. In the event of a relevant risk of harm as a result of prioritization, these decisions should be made by means of a team approach. Gender, age, disability, ethnicity, origin, and other social characteristics, such as social or insurance status, as well as the vehemence of a patient's treatment request and SARS-CoV-2 vaccination status should not be used as prioritization criteria. The guideline provides concrete recommendations for (1) diagnostic procedures, (2) surgical procedures for cancer, and (3) systemic treatment and radiotherapy in patients with colorectal or pancreatic cancer within the context of the German healthcare system.

Introduction: Breast cancer (BC) is one of the most common tumors; better screening policies and multidisciplinary approach allow personalized treatment. Radiotherapy (RT) plays a central role in the multimodal approach in BC, and recent evidence has shown the non-inferiority of hypofractionated treatments. The aim of this study was to describe the feasibility and validity of stereotactic RT (SBRT) in BC in a neoadjuvant and exclusive setting. Methods: A PubMed/MEDLINE and Embase systematic review was conducted to assess the role of radiomics in BC. The search strategy was "breast [All Fields] AND "stereotactic" [All Fields] AND "radiotherapy" [All Fields]" and only original articles referred to BC in humans in the English language were considered. Results: A total of 2,149 studies were obtained using the mentioned search strategy on PubMed and Embase. After the complete selection process, a total of 12 papers were considered eligible for the analysis of the results. SBRT in BC was described in 8 studies regarding neoadjuvant approach and 4 papers regarding exclusive approach. Conclusions: Relative low toxicity rates, the reduced treatment volumes in the neoadjuvant setting, and the possibility to replace surgery when not feasible in exclusive setting resulted to be main advantages for SBRT in BC. Current evidence shows that both the neoadjuvant and the definitive settings seem to be promising clinical scenarios for SBRT, especially for EBC. [ABSTRACT FROM AUTHOR]

Background: Management of Ras wild-type colorectal cancer (CRC) patients upon disease progression after the successful use of targeted treatment with anti-EGFR monoclonal antibodies and backbone chemotherapy remains a clinical challenge. Summary: Development of treatment resistance with prevalence of preexisting RAS mutated clones, RAS mutation conversion, truncation of extracellular receptor domains as well as HER2 and MET amplification are molecular events that can be difficult to follow without the use of sophisticated laboratory techniques. The clinical hurdle of re-biopsy and tumor heterogeneity can be overcome by the implementation of next-generation sequencing (NGS) to analyze circulating tumor DNA (ctDNA) and identify druggable mutations or recovery of RAS-wildness. In this opinion paper, we summarize with critical thinking the clinical approach to be followed after the failure of first-line treatment in Ras wild-type CRC tumors with the use of NGS. Rechallenge with anti-EGFR inhibitors, in case of persistent or recovery of RAS-wildness, and targeted approach of specific mutations (BRAF inhibitors), amplifications (anti-Her2 treatment), or fusion proteins (NTRK inhibitors) can by guided by the use of NGS. The use of NGS platforms for serial analysis of ctDNA is an important step to better understand the molecular landscape of metastatic CRC and guide clinical decisions. Key Messages: NGS should be considered a mainstay in clinical practice for the management of CRC patients and health authorities should consider reimbursing its use in the appropriate clinical settings.

Background: Within the theoretical framework of the ICD diagnostic criteria of cancer-related fatigue, we aim to investigate how those criteria can be used for screening purposes. Methods: Fatigue was assessed in a mixed sample of 1,225 cancer patients during their stay in a rehabilitation clinic using four different fatigue measures and the diagnostic criteria (Criterion A; DC-A). Psychometric evaluations (e.g., acceptance, reliability, validity, item analyses) were conducted for the sum score and for all items of the diagnostic criteria. Results: A total of 678 (57.1%) patients tested positive according to the DC-A. The sum score of the DC-A had good reliability (Cronbach's alpha = 0.87) and validity, corresponded closely with other fatigue scales, and, with less than 1% missing values, showed a high degree of patients' acceptance. The highest accuracy (approx. 0.80) and Youden indices (>0.55) were found for the items "Difficulties completing daily tasks" (A9), "Struggle to overcome inactivity" (A7), "Decreased motivation or interests" (A4), and "Unrefreshing sleep" (A6). Conclusion: The DC-A proved to be a well-accepted, easy to use, and reliable tool for measuring the severity of fatigue. In this paper, we make suggestions for the use of single items of the DC-A as a short and economical screening tool. [ABSTRACT FROM AUTHOR]

In recent years, the term "value-based healthcare" has been increasingly used in debates about costs and outcomes of health interventions in cancer care. This paper distinguishes 2 meanings of the term "value" and explores the relevance of both meanings of the word for assessing the "value" of cancer drugs. At the focus of the analysis are value judgments which form an integral part of the assessment of benefit of cancer drugs. The review concludes with a reflection on individual competences and systemic factors which are relevant to decision making about the value of treatment in situations of non-curative cancer.

This paper describes the function and contribution of family-oriented oncologic rehabilitation (FOR) and of oncologic rehabilitation for adolescents and young adults (AYA). The rehabilitation of children with cancer and their families and that of AYA is an integral component of pediatric oncologic treatment regimens. 32 years ago, FOR was developed in Germany and continues in a select number of highly-specialized rehabilitation centers recommended by the GPOH (Gesellschaft für Pädiatrische Onkologie und Hämatologie, Society of Pediatric Oncology and Hematology). After oncologic treatment, the patient, along with his or her family, begins an individualized rehabilitation process. The whole family participates in this process to ensure success. AYA patients are rehabilitated in small peer groups. In FOR, the immediate goal is to stabilize the family system in order to ensure maximum success for the patient. The long-term goal of FOR and AYA rehabilitation is to provide support for a return to as normal and self-determined a life as possible. Patients who suffer from chronic illnesses due to their oncologic disease and therapy (for example, a significant number of brain tumor patients) need longterm help in various areas. Here, multiple 4-week cycles of oncologic rehabilitation may be necessary throughout a patient's lifetime. [ABSTRACT FROM AUTHOR]

Immune checkpoint inhibitors are emerging as a therapeutic approach for patients with advanced or metastatic gastrointestinal malignancies following the recent Food and Drug Administration and Asian approvals for colorectal, gastric, and hepatocellular carcinoma. As discussed in earlier articles, phase I-II trials demonstrate quite positive clinical activity, particularly in patients with immunogenic cancer subtypes. This outreach paper discusses some of the next innovative immunotherapy strategies under development. Here, tumor-associated macrophages, myeloid-derived suppressor cells, and regulatory T cells are increasingly coming into focus as new targets. Besides the well described use of checkpoint inhibitors, blockade of ‘Wnt' or Csf1R signaling pathways as well as combinatorial treatment strategies offer promising examples for overcoming immune silencing within the resistant tumor microenvironment.
