Résumé
Background@#Data on the clinical characteristics and outcomes of Filipino cancer patients who acquired the coronavirus disease 2019 (COVID-19) are limited and local information is lacking. Here we characterize the outcomes of patients with cancer and COVID-19.@*Methods@#Medical records of Filipino cancer patients with COVID-19 from the University of the Philippines – Philippine General Hospital (UP-PGH), Southern Philippines Medical Center (SPMC), De La Salle – University Medical Center (DLS- UMC), and St Luke’s Medical Center (SLMC) from March to December 2020 were reviewed.@*Results@#Sixty-nine cancer patients were identified to have COVID-19. The mean age was 53 years (range 19-88) and 45 (65%) patients were female. The most prevalent malignancies were from the gastrointestinal tract (16 [23%]) and the breast (14 [20%]). The majority (34 [49%]) had metastatic disease and had a functional status of Eastern Cooperative Oncology Group (ECOG) 2 or worse (39 [57%]). Forty-two (61%) patients had active oncologic treatment given for the past three months and twenty-four (35%) of these patients were on chemotherapy. The most common symptoms upon presentation were cough (34 [49%]) followed by dyspnea (28 [41%]). COVID-19 severity of this series was as follows: 15 mild (22%), 32 moderate (46%), 7 severe (10%), and 15 critical (22%). The majority received intravenous antibiotics (54 [78%]), investigational treatments (27 [39%]), and steroids (20 [29%]). Common complications were acute respiratory failure (20 [29%]), acute respiratory distress syndrome (17 [25]), and septic shock (15 [22%]). At the end of the collection period, 21 (30%) cancer patients died. The mean length of hospital stay was 22 days.@*Conclusion@#Based on the findings of our case series, ECOG 2 and higher, metastatic stage, higher neutrophil to lymphocyte ratio showed a trend to worse outcomes. Cancer-related treatment within the past months did not appear to affect outcomes.

PURPOSE: BioPATH is a non-interventional study evaluating the relationship of molecular biomarkers (PTEN deletion/downregulation, PIK3CA mutation, truncated HER2 receptor [p95HER2], and tumor HER2 mRNA levels) to treatment responses in Asian patients with HER2+ advanced breast cancer treated with lapatinib and other HER2-targeted agents. MATERIALS AND METHODS: Female Asian HER2+ breast cancer patients (n=154) who were candidates for lapatinib-based treatment following metastasis and having an available primary tumor biopsy specimen were included. The primary endpoint was progression-free survival (PFS). Secondary endpoints were response rate, overall survival on lapatinib, correlation between biomarker status and PFS for any previous trastuzumab-based treatment, and conversion/conservation rates of the biomarker status between tissue samples collected at primary diagnosis and at recurrence/metastasis. Potential relationships between tumor mRNA levels of HER2 and response to lapatinib-based therapy were also explored. RESULTS: p95HER2, PTEN deletion/downregulation, and PIK3CA mutation did not demonstrate any significant co-occurrence pattern and were not predictive of clinical outcomes on either lapatinib-based treatment or any previous trastuzumab-based therapy in the metastatic setting. Proportions of tumors positive for p95HER2 expression, PIK3CA mutation, and PTEN deletion/down-regulation at primary diagnosis were 32%, 31.2%, and 56.2%, respectively. Despite limited availability of paired samples, biomarker status patterns were conserved in most samples. HER2 mRNA levels were not predictive of PFS on lapatinib. CONCLUSION: The prevalence of p95HER2 expression, PIK3CA mutation, and PTEN deletion/downregulation at primary diagnosis were similar to previous reports. Importantly, no difference was observed in clinical outcome based on the status of these biomarkers, consistent with reports from other studies.
