Incidence and real-world burden of brain metastases from solid tumors and hematologic malignancies in Ontario: a population-based study.

ABSTRACT:

Background

Although intracranial metastatic disease (IMD) is a frequent complication of cancer, most cancer registries do not capture these cases. Consequently, a data-gap exists, which thwarts system-level quality improvement efforts. The purpose of this investigation was to determine the real-world burden of IMD.

Methods

Patients diagnosed with a non-CNS cancer between 2010 and 2018 were identified from the Ontario Cancer Registry. IMD was identified by scanning hospital administrative databases for cranial irradiation or coding for a secondary brain malignancy (ICD-10 code C793).

Results

25,478 of 601,678 (4.2%) patients with a diagnosis of primary cancer were found to have IMD. The median time from primary cancer diagnosis to IMD was 5.2 (0.7, 15.4) months and varied across disease sites, for example, 2.1 months for lung, 7.3 months for kidney, and 22.8 months for breast. Median survival following diagnosis with IMD was 3.7 months. Lung cancer accounted for 60% of all brain metastases, followed by breast cancer (11%) and melanoma (6%). More advanced stage at diagnosis and younger age were associated with a higher likelihood of developing IMD (P < .0001). IMD was also associated with triple-negative breast cancers and ductal histology (P < .001), and with small-cell histology in patients with lung cancer (P < .0001). The annual incidence of IMD was 3,520, translating to 24.2 per 100,000 persons.

Conclusion

IMD represents a significant burden in patients with systemic cancers and is a significant cause of cancer mortality. Our findings support measures to actively capture incidents of brain metastasis in cancer registries.

Project description:INTRODUCTION:Chemotherapy-induced myelosuppression (CIM) is one of the most common dose-limiting complications of cancer treatment, and is associated with a range of debilitating symptoms that can significantly impact patients' quality of life. The purpose of this study was to understand patients' perspectives on how the side effects of CIM are managed in routine clinical practice. METHODS:An online survey was conducted of participants with breast, lung, or colorectal cancer who had received chemotherapy treatment within the past 12 months, and had experienced at least one episode of myelosuppression in the past year. The survey was administered with predominantly close-ended questions, and lay definitions of key terms were provided to aid response selection. RESULTS:Of 301 participants who completed the online survey, 153 (51%) had breast cancer, 100 (33%) had lung cancer, and 48 (16%) had colorectal cancer. Anemia, neutropenia, lymphopenia, and thrombocytopenia were reported by 61%, 59%, 37%, and 34% of participants, respectively. Most participants (79%) reported having received treatment for CIM, and 64% of participants recalled chemotherapy dose modifications as a result of CIM. Although most participants believed their oncologist was aware of the side effects of CIM, and treated them quickly, 30% of participants felt their oncologists did not understand how uncomfortable they were due to the side effects of CIM. Overall, 88% of participants considered CIM to have a moderate or major impact on their lives. CONCLUSION:The data highlight that despite the various methods used to address CIM, and the patient-focused approach of oncologists, the real-world impact of CIM on patients is substantial. Improving communication between patients and health care providers may help improve patients' understanding of CIM, and foster shared decision-making in terms of treatment. Additional insights from patients should be obtained to further elucidate the totality of life burden associated with CIM.

Project description:Abstract Background: PRO1160 is a novel antibody-drug conjugate (ADC) directed to CD70, an antigen mediating immuno-suppression that is overexpressed in multiple solid tumors and hematologic malignancies, with limited distribution in normal tissues. PRO1160 comprises (1) a human monoclonal antibody specific for CD70, (2) a protease-cleavable proprietary hydrophilic linker, and (3) exatecan, a topoisomerase 1 inhibitor. Comprehensive prior work demonstrated that the hydrophilic linker confers excellent physicochemical properties and pharmacokinetics (PK) across a range of payload mechanisms and is superior to conventional linkers on these critical parameters for ADCs. In addition, exatecan is broadly active in many tumor types, is membrane permeable, and is not a substrate of multidrug resistance pumps, thus likely lending strong bystander effects and durable treatment responses. PRO1160 is highly potent in cell-derived xenograft models of renal cell carcinoma (RCC), non-Hodgkin lymphoma (NHL), and nasopharyngeal carcinoma (NPC). PRO1160 also demonstrates marked antitumor activity in patient-derived xenograft models of diverse tumor sites, histologies, molecular subtypes, target expression levels, and Epstein Barr Virus status. PRO1160 is stable in circulation and displays PK characteristics indistinguishable from the parent antibody in rats. In a GLP toxicity study in cynomolgus monkeys, the primary PRO1160-related toxicity resided in the thymus and bone marrow, was consistent with exatecan toxicities, and was reversible. PRO1160-001 is an ongoing, open-label Phase 1/2 study to evaluate the safety, tolerability, PK, and antitumor activity of PRO1160 in patients with metastatic RCC, metastatic or relapsed NPC, or advanced relapsed/refractory NHL. Patients must have measurable disease per the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 or the Lugano Classification for NHL. Patients must also have previously received therapies known to confer clinical benefit unless considered ineligible, refused by the patient, or not available in the region. PRO1160 is given by intravenous infusion on Day 1 of a 21-day cycle and treatment may continue until disease progression, unacceptable toxicity, or other reason for discontinuation. The primary objectives are to evaluate the safety and tolerability of PRO1160 and to identify the maximum tolerated dose, if reached, and recommended phase 2 dose (RP2D). This study consists of 2 parts, Part A: dose-escalation and dose-level expansion, and Part B: 3 tumor-specific expansion cohorts (metastatic RCC, metastatic or relapsed NPC, or advanced relapsed/refractory NHL) treated at the RP2D. PK, immunogenicity, and antitumor activity will also be evaluated. The study is currently enrolling at sites in the US, with future enrollment in China planned (Clinicaltrials.gov: NCT05721222).
