    Abstract The outcomes of patients with genitourinary (GU) cancers have been steadily improving in recent years. Novel therapies have entered our armamentarium, while several other regimens are currently being studied in clinical trials. This recent explosion of new agents has improved patient survival and the quality of life for patients, but has also significantly increased the frequency of several side effects. The current review will focus on the potential ocular adverse reactions of GU neoplastic treatments. The broad spectrum of manifestations of ocular toxicity underscores the uniqueness and complexity of the anatomic, physiologic, and metabolic features of the human eye. Most side effects are mild in severity and transient, but some can be severe, disabling, and irreversible. Clinicians should be aware of complications that might be vision threatening and impact the patient's quality of life. In this review, we focused on the ocular toxicity of the antineoplastic regimens that are currently used for the treatment of GU, including prostate cancer, bladder cancer, renal cell carcinoma, testicular cancer, pheochromocytoma, adrenocortical carcinoma, and penile cancer.

    Abstract Background: Current treatment recommendations for high grade non-metastatic osteosarcoma include perioperative chemotherapy and surgery. Despite this intensive protocol, approximately 40% of patients will relapse. The addition of the immunomodulator mifamurtide to adjuvant cytotoxic chemotherapy was associated with a significant improvement in 6-year overall survival (OS) in young patients with resectable osteosarcoma, leading to its approval in Europe and other countries. Very limited real-world data are reported on its use.
    Methods: We retrospectively evaluated data from osteosarcoma patients who received mifamurtide in the adjuvant setting. Data were obtained from medical records in 2 high-volume bone sarcoma centers. The aim of this study was to collect real-world data on mifamurtide safety and efficacy in Greece.
    Results: We identified 15 patients with completely resected osteosarcoma who received mifamurtide from September 2015 to January 2020. Median age at diagnosis was 24 years old (16-76). Osteosarcoma arose in the lower extremities (n = 12), in the upper extremities (n = 2) or in the ilium (n = 1). The majority of patients (n = 13) received cisplatin/doxorubicin/methotrexate as perioperative chemotherapy and the remaining patients cisplatin/doxorubicin. After a median follow-up of 46.9 months (range, 32.8-61.1), the median recurrence-free survival was 58.7 months (range, 18.5-98.8) and the median OS 64.1 months (range, 25.6-102.6). Except for fever and chills, the only adverse event probably related to mifamurtide was pericarditis (n = 1).
    Conclusions: Mifamurtide was well tolerated in a Greek osteosarcoma population, including patients older than 30 years. The small sample size and the non-comparative design do not allow drawing conclusions on the drug benefit in terms of survival.

    Abstract Background: Adjuvant chemotherapy has an indisputable value for early breast cancer patients. Anthracycline and taxane-based regimens (TaxAC) have not been proven superior to taxane & cyclophosphamide (TC), a less toxic combination. Our objective was to estimate the cumulative evidence for non-inferiority of TC against TaxAC, in the adjuvant setting of patients with HER2-negative, breast cancer.
    Results: Overall, 7,341 patients were included in this analysis. Superiority of TaxAC or non-inferiority of TC was not established either for the overall population (DFS HR, 1.11; 95% CI, 0.95-1.30;
    Conclusion: Although non-inferiority of TC was not proven, superiority of TaxAC is still questioned. The present analysis narrows the risk of recurrence between the treatment groups. Considering TC has a more favorable safety profile, the question as to which treatment regimen should be preferred under what circumstances, needs to be individualized according to patients' characteristics and desires.
    Methods: Treatment efficacy data from The ABC trials, the Plan B trial and a trial by the Hellenic Oncology Research group (HORG) were pooled. Disease free survival (DFS) and overall survival (OS) were scrutinized. A HR of 1.18 for TC versus TaxAC was chosen to demonstrate inferiority.

    Abstract Introduction/background: Adjuvant capecitabine monotherapy is an option for colon and upper rectum adenocarcinoma patients, providing they have stage II disease with an intermediate risk of recurrence, or stage III but they are above 70's or they have comorbidities. We wanted to examine whether the number of chemotherapy cycles and the relative dose intensity (RDI) of capecitabine monotherapy in the adjuvant setting are affecting disease recurrence.
    Patients and methods: We included patients with completely resected stage II and III colon and upper rectum cancer who received adjuvant capecitabine monotherapy, from 2003 until May 2020. Patients with early relapse, i.e. during chemotherapy or within 6 months after the completion of adjuvant chemotherapy, and those with rectal cancer who received radiotherapy were excluded. Patients were divided into 3 groups based on the number of chemotherapy cycles received and the RDI. Group A included patients with ≤4 cycles of chemotherapy, group B patients with >4 cycles of chemotherapy and RDI ≤80%, and group C patients with >4 cycles of chemotherapy and RDI >80%. Study's endpoint, was recurrence free survival (RFS).
    Results: Two hundred twenty six patients with stage II and III disease (164 and 62 respectively) were included. Sixteen, 166 and 44 were included in groups A, B and C respectively. After a median follow-up of 41 months, 21 patients (9,3%) had relapsed. Patients belonging to group C were found to have a trend for lower relapse rate compared to patients belonging to group A or group B.
    Conclusion: Number of adjuvant capecitabine cycles and RDI might play a role in RFS in patients with stage II and III colon and upper rectum adenocarcinoma.

    Abstract Chondrosarcoma is a rare malignancy characterized by the production of cartilage matrix, displaying heterogeneous histopathology and clinical behavior. Due to lack of effective treatment for advanced disease, the clinical management of metastatic chondrosarcoma is exceptionally challenging. Chondrosarcomas harbor molecular abnormalities, such as overexpression of platelet-derived growth factor receptor (PDGFR)-alpha and PDGFR-beta, which are required for cancer development, progression, and metastasis. Pazopanib is a potent and selective multitargeted tyrosine kinase inhibitor, which co-inhibits stem cell growth factor receptor (c-KIT), fibroblast growth factor receptor (FGFR), PDGFR, and vascular endothelial growth factor receptor (VEGFR) and has demonstrated clinical activity in patients with advanced previously treated soft tissue sarcoma. Herein, we describe the unique case of a patient with metastatic chondrosarcoma who derived clinical benefit from pazopanib after first-line chemotherapy failure.

    Abstract Purpose: To present our experience on the use of Brentuximab Vedotin (BV) in patients with relapsed/refractory classical Hodgkin Lymphoma (cHL) and severe liver function impairment with marked jaundice.
    Methods: Two patients with relapsed/refractory cHL were evaluated. BV was administered in the presence of liver dysfunction and severe jaundice due to liver infiltration by cHL, as confirmed by PET-CT. Complete blood counts, biochemical profile, physical and imaging findings were reviewed to assess BV efficacy and tolerance.
    Results: Case 1 had stage IVB, mixed cellularity cHL. Following ABVD chemotherapy, the patient experienced a relapse and responded to IGEV (ifosfamide, gemcitabine, vinorelbine, steroids) chemotherapy followed by autologous stem cell transplantation (ASCT). Thereafter, he experienced a second relapse with constitutional symptoms, severe jaundice and pancytopenia. Liver involvement was confirmed by PET-CT. Case 2 was admitted with a very late relapse of cHL. After a single cycle of gemcitabine-vinorelbine chemotherapy, which was not tolerated, the patient developed fever, anemia and jaundice, with laboratory findings indicating bone marrow and liver infiltration. The latter was confirmed by PET-CT. Both patients received BV monotherapy according to its formal indication at the reduced dose of 1.2 mg/kg due to severe liver impairment and experienced a rapid clinical and laboratory improvement. BV was well tolerated and offered a clinical benefit for approximately 4 months.
    Conclusions: BV was safely administered to patients with relapsed/refractory cHL and severe liver function impairment with marked jaundice due to liver involvement, offering significant clinical improvement and reversal of liver abnormalities. BV may serve as a bridge to further salvage combination chemotherapy or a transplant procedure.
