Background: The term phyllodes tumours, which account for less than 1% of breast neoplasms, describes a spectrum of heterogenous tumours with different clinical behaviours. Less than 30% present as metastatic disease. Complete surgical resection is the standard of care so that recurrence rates are reduced. The role of adjuvant chemotherapy or radiation therapy is controversial. Patients with metastatic disease have a median overall survival of around 30 months. Case description: The authors present the case of a 57-year-old woman with an exuberant left malignant phyllodes tumour with bilateral involvement, as well as lung and axillar metastasis. The patient underwent haemostatic radiation therapy and started palliative chemotherapy with doxorubicin, achieving partial response with significant improvement in quality of life. A posterior simple mastectomy revealed a small residual tumour. Discussion: Metastatic malignant phyllodes tumours are rare, so therapeutic strategies rely on small retrospective studies and guidelines for soft tissue sarcoma. Palliative chemotherapy protocols include anthracycline-based regimens, either as monotherapy with doxorubicin or doxorubicin together with ifosfamide. With few treatment options, management of these patients must rely on a continuum of care

Objective COVID-19 vaccines have shown efficacy and safety in healthy people. However, cancer patients under active immunosuppressive treatment were not included in the clinical trials conducted to test vaccines' efficacy and safety. This study aimed to evaluate the COVID-19 vaccine acceptance in cancer patients undergoing immunosuppressive therapy. Methods A total of 200 adult cancer patients received a questionnaire between March 8 and April 2, 2021, before the beginning of cancer patients' vaccination in Portugal. The questionnaire adapted from previously conducted studies included 11 close-ended items, evaluating variables such as patient sociodemographic and clinical characteristics, and the acceptance and underlying reasons to be or not to be vaccinated. The primary outcome was the intended acceptance of the COVID-19 vaccine in cancer patients. Multiple logistic regression was performed to identify factors associated with intended acceptance. Results Among the 200 delivered questionnaires, only 169 were included in this study. From those, 142 (84%) patients intended to be vaccinated against COVID-19. Only 27 participants (16%) had not yet decided or were reluctant to COVID-19 vaccination. High school degree (odds ratio (OR) 0.133, 95% confidence interval (C.I.) 0.031-0.579, p = 0.007], rural residence (OR 0.282, 95% C.I. 0.081-0.984, p = 0.047), and reluctance in believing in the vaccine efficacy (OR 0.058, 95% C.I. 0.016-0.204, p < 0.001] were identified predictors factor for COVID-19 vaccine hesitancy. Conclusion Most patients intended to be vaccinated against COVID-19, and specific factors such as education level, rural residence and the belief in vaccine efficacy were related to vaccine acceptance.

BACKGROUND Glioblastoma (GBM) is the most common and aggressive primary malignant brain tumour in adults. The current standard of care for newly diagnosed GBM is maximal surgical resection, followed by radiotherapy plus concomitant and adjuvant temozolomide (TMZ). This study aimed to evaluate the survival outcomes and identify predictors of survival among these patients. MATERIAL AND METHODS We performed a single-centre retrospective analysis of GBM patients treated with radiotherapy plus concomitant and adjuvant TMZ from 2013 to 2020. The analyses of progression-free survival (PFS) and overall survival (OS), each one evaluated starting from initial diagnosis, were performed. Survival curves were estimated with the Kaplan- Meier method and compared using the log-rank test. RESULTS Fifty-eight patients were identified. The median age was 61 years (range 18- 80), 51 (88%) patients were in ECOG-PS 0–1, 6 (10%) patients had isocitrate dehydrogenase (IDH) mutation and 53 (91%) of patients had undergone debulking surgery. At a median follow-up of 21 months, median OS was 12.8 months (95% confidence interval [CI] 9.7–15.9), whereas median PFS was 9.5 months (95% CI 8.5–10.5). The 1-year survival rate was 42% and the 2-year survival rate was 10%. Grade 3 or 4 hematologic toxicity occurred in 11 (19%) patients. Twenty-five (42%) patients completed at least 6 cycles of TMZ monotherapy with statistically significant differences between this sub-group and those who weren’t able to continue TMZ monotherapy [median OS 19.3 months (95% CI 14.4–24.2) vs 10.6 months (95% CI 7.8–13.4) p&lt;0.001]. ECOG-PS = 0 [median OS 16.7 months (95% CI 13.4–20.0, p=0.001)] and patients under 65 years of age [median OS 15.6 months (95% CI 12.3–18.9, p=0.02) were associated with significantly better median OS. CONCLUSION The current standard of care treatment for GBM remains poor. An important factor predictor of survival is the completion of the 6 maintenance cycles of TMZ. At baseline, ECOG PS and the patient’s age could be used to define patient prognosis.

Background: Cancer p represent a high-risk population for severe COVID-19. Cancerassociated immunosuppression may hinder in the development of anti-SARS-CoV-2 antibodies.
