Tucatinib Combination Treatment After Trastuzumab-Deruxtecan in Patients With ERBB2-Positive Metastatic Breast Cancer.

Importance: Little is known regarding the outcomes associated with tucatinib combined with trastuzumab and capecitabine (TTC) after trastuzumab-deruxtecan exposure among patients with ERBB2 (previously HER2)-positive metastatic breast cancer (MBC). Objective: To investigate outcomes following TTC treatment in patients with ERBB2-positive MBC who had previously received trastuzumab-deruxtecan. Design, Setting, and Participants: This cohort study included all patients with MBC who were treated in 12 French comprehensive cancer centers between August 1, 2020, and December 31, 2022. Exposure: Tucatinib combined with trastuzumab and capecitabine administered at the recommended dose. Main Outcomes and Measures: Clinical end points included progression-free survival (PFS), time to next treatment (TTNT), overall survival (OS), and overall response rate (ORR). Results: A total of 101 patients with MBC were included (median age, 56 [range, 31-85] years). The median number of prior treatment lines for metastatic disease at TTC treatment initiation was 4 (range, 2-15), including 82 patients (81.2%) with previous trastuzumab and/or pertuzumab and 94 (93.1%) with previous ado-trastuzumab-emtansine) exposure. The median duration of trastuzumab-deruxtecan treatment was 8.9 (range, 1.4-25.8) months, and 82 patients (81.2%) had disease progression during trastuzumab-deruxtecan treatment, whereas 18 (17.8%) had stopped trastuzumab-deruxtecan for toxic effects and 1 (1.0%) for other reasons. Tucatinib combined with trastuzumab and capecitabine was provided as a third- or fourth-line treatment in 37 patients (36.6%) and was the immediate treatment after trastuzumab-deruxtecan in 86 (85.1%). With a median follow-up of 11.6 (95% CI, 10.5-13.4) months, 76 of 101 patients (75.2%) stopped TTC treatment due to disease progression. The median PFS was 4.7 (95% CI, 3.9-5.6) months; median TTNT, 5.2 (95% CI, 4.5-7.0) months; and median OS, 13.4 (95% CI, 11.1 to not reached [NR]) months. Patients who received TTC immediately after trastuzumab-deruxtecan had a median PFS of 5.0 (95% CI, 4.2-6.0) months; median TTNT of 5.5 (95% CI, 4.8-7.2) months, and median OS of 13.4 (95% CI, 11.9-NR) months. Those who received TTC due to trastuzumab-deruxtecan toxicity-related discontinuation had a median PFS of 7.3 (95% CI, 3.0-NR) months. Best ORR was 29 of 89 patients (32.6%). Sixteen patients with active brain metastasis had a median PFS of 4.7 (95% CI, 3.0-7.3) months, median TTNT of 5.6 (95% CI, 4.4 to NR), and median OS of 12.4 (95% CI, 8.3-NR) months. Conclusions and Relevance: In this study, TTC therapy was associated with clinically meaningful outcomes in patients with ERBB2-positive MBC after previous trastuzumab-deruxtecan treatment, including those with brain metastases. Prospective data on optimal drug sequencing in this rapidly changing therapeutic landscape are needed.

Development and Validation of an Inflammatory Prognostic Index to Predict Outcomes in Advanced/Metastatic Urothelial Cancer Patients Receiving Immune Checkpoint Inhibitors.

BACKGROUND: Immune checkpoint inhibitors (ICIs) improve overall survival (OS) in advanced/metastatic urothelial cancer (a/mUC) patients. Preliminary evidence suggests a prognostic role of inflammatory biomarkers in this setting. We aimed to develop a disease-specific prognostic inflammatory index for a/mUC patients on ICIs. METHODS: Fifteen variables were retrospectively correlated with OS and progression-free survival (PFS) in a development (D, n = 264) and a validation (V, n = 132) cohort of platinum-pretreated a/mUC pts receiving ICIs at L2 or further line. A nomogram and inflammatory prognostic index (U-IPI) were developed. The index was also tested in a control cohort of patients treated with chemotherapy only (C, n = 114). RESULTS: The strongest predictors of OS were baseline platelet/lymphocyte (PLR) and neutrophil/lymphocyte (NLR) ratios, and lactate dehydrogenase (LDH), NLR, and albumin changes at 4 weeks. These were used to build the U-IPI, which can distinctly classify patients into good or poor response groups. The nomogram scoring is significant for PFS and OS (p < 0.001 in the D, V, and combined cohorts) for the immunotherapy (IO) cohort, but not for the control cohort. CONCLUSIONS: The lack of a baseline systemic inflammatory profile and the absence of early serum inflammatory biomarker changes are associated with significantly better outcomes on ICIs in a/mUC pts. The U-IPI is an easily applicable dynamic prognostic tool for PFS and OS, allowing for the early identification of a sub-group with dismal outcomes that would not benefit from ICIs, while distinguishing another that draws an important benefit.

Telehealth in breast cancer following the coronavirus disease 2019 pandemic.

Breast cancer (BC) is the second most diagnosed cancer in 2018 with around 2.3 million cases globally in 2020. In March 2020 and after its worldwide spread, the World Health Organization (WHO) declared the coronavirus disease 2019 (COVID-19) outbreak, a respiratory disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, a pandemic. During this time, cancer patients were heavily impacted and their treatment plans were changed due to measures to fight the disease and solutions had to be found to maintain their follow-up and management from a distance. Some cancer groups worldwide have recommended then the use of telemedicine for oncology patients to ensure the continuity of medical care during the pandemic. This method was considered effective and clinicians worldwide continued using telehealth even after the cessation of worldwide restrictions. To this end, current up-to-date data on the use of telemedicine in BC patient after the COVID-19 outbreak are summarized in this narrative review.

Provision of Lifestyle Recommendations to Cancer Patients: Results of a Nationally Representative Survey of Hematologists/Oncologists.

Adopting a healthy lifestyle during cancer treatment enhances patients' outcomes. The purpose of this study is to evaluate the current practices and attitudes adopted by hematologists/oncologists on providing lifestyle recommendations to cancer patients. The secondary objective includes a correlation between the hematologists/oncologists' sociodemographic with their provision of lifestyle recommendations to their patients. This prospective, cross-sectional study surveyed Lebanese hematologists/oncologists in five major Lebanese governorates. The questionnaire collected information on participants' demographics and personal lifestyle choices as well as practices and perceptions related to lifestyle recommendations provided to cancer patients. A total of 40 hematologists/oncologists practicing in Lebanon completed the questionnaire with a response rate of 33.3%. The top three recommendations that hematologists/oncologists provided to their patients include quit smoking (95%), increase your physical activity (92.5%), and improve your nutrition/diet (85%). The mean number of recommendations provided per hematologist/oncologist was 3.88 (± 1.067). These discussions were consistently provided during clinical encounters with patients. The most frequently reported barriers hindering patient education on lifestyle recommendations included practitioners' lack of time and knowledge and patients' advanced stages of cancer and lack of interest in the topic. Hematologists/oncologists perceived these recommendations to be beneficial to patients' mental health and performance status, while few of them identified other benefits. Only one statistically significant correlation was identified between hematologists/oncologists' sociodemographic and providing the lifestyle recommendations to their patients. To achieve higher quality patient-centered care, communication gaps between hematologists/oncologists and cancer patients should be addressed, and solutions to identified barriers should be implemented.

Survival Pattern of Hodgkin Lymphoma Patients in the Last 25 Years in Lebanon.

CONTEXT: After the emergence of combination chemotherapy in 1960s, survival of patients with Hodgkin lymphoma (HL) has dramatically improved worldwide. We lack studies that document the favorable evolution of survival regarding this disease in Lebanon. OBJECTIVE: To compare the overall survival in HL over 3 different decades in Lebanon. METHODS: We retrospectively reviewed the charts of 196 patients diagnosed with HL, treated and followed from 1990 to 2015 in our center. Patients were divided into 3 groups according to period of analysis: group A (1990-1999), group B (2000-2009), and group C (2010-2015). We studied the characteristics and survival patterns of patients in each group. RESULTS: The male-to-female sex ratio was 1.06. The median age at diagnosis was 33 years in group A, 30.4 in group B, and 33.12 in group C (P = .6). Results showed variations in the subtypes of the disease according to the following: nodular-sclerosis HL 59.5% in group A, 76.2% in group B, and 85.4% in group C. Mixed cellularity HL 21.6% in group A, 2.4% in group B, and 73.7% in group C (P = .0001). Patients presented with localized disease in 58.6%, 73.7%, and 56.4% in groups A, B, and C, respectively (P = .173). Complete remission was achieved in 76.5% in group A, 85.3% in group B, and 69.5% in group C (P = .007). The survival rate at 5 years in group A was 91%, 94% in group B, and 100% in group C. CONCLUSION: The survival of patients with HL has dramatically improved over the past 25 years in Lebanon. These results resemble those achieved in Western countries due to the fast adoption of new molecular imaging technologies at diagnosis and follow-up and the rapid approval of new drugs for relapse in the Lebanese market.

Real-life Experience for Integration of PET-CT in the Treatment of Hodgkin Lymphoma in Lebanon.

BACKGROUND: Hodgkin lymphoma (HL) is a highly curable disease; < 80% of patients will achieve long-term survival. Positron emission tomography-computed tomography (PET-CT) has played a major role in the evaluation of both disease staging and response and has become an essential component in tailoring patients' treatment. We report the effect of integrating PET-CT into the management of HL in Lebanon. PATIENTS AND METHODS: We analyzed the data regarding the usage of PET-CT at diagnosis, during treatment (interim PET), and at the end of treatment. We also analyzed the PET-CT findings from 2009 to 2015. RESULTS: The first PET-CT system was introduced in Lebanon in April 2002 but was not used for the evaluation of HL. Early in 2009, we started to incorporate PET-CT into the treatment of HL. By the end of 2009, 70% of patients were undergoing PET-CT at diagnosis and at the end of treatment. This proportion remained constant until 2013, when an increase occurred, with ≤ 94% of patients undergoing PET-CT at diagnosis. The usage of CT at diagnosis decreased significantly from 70% before 2009 to 52% after 2015. In contrast, CT usage at the end of treatment has fluctuated from 10% in 2009 to 0% in 2012, 2013, and 2014 and 11.76% in 2015. CONCLUSION: Functional imaging techniques are increasing in popularity compared with anatomic imaging. The usage of PET-CT has emerged as a highly valuable staging and follow-up method in the treatment of HL 8 years after the introduction of PET in Lebanon. PET was used first to improve the staging, then to evaluate the treatment response, and, recently, to tailor therapy according to the response.
