Outcomes and Prognostic Factors in a Large Cohort of Hospitalized Cancer Patients With COVID-19.

PURPOSE: Patients with cancer are at increased risk for unfavorable outcomes from COVID-19. Knowledge about the outcome determinants of severe acute respiratory syndrome coronavirus 2 infection in this population is essential for risk stratification and definition of appropriate management. Our objective was to evaluate prognostic factors for all-cause mortality in patients diagnosed with both cancer and COVID-19. METHODS: All consecutive patients with cancer hospitalized at our institution with COVID-19 were included. Electronic medical records were reviewed for clinical and laboratory characteristics potentially associated with outcomes. RESULTS: Five hundred seventy-six consecutive patients with cancer and COVID-19 were included in the present study. An overall in-hospital mortality rate of 49.3% was demonstrated. Clinical factors associated with increased risk of death because of COVID-19 were age over 65 years, Eastern Cooperative Oncology Group performance status > 0 zero, best supportive care, primary lung cancer, and the presence of lung metastases. Laboratory findings associated with a higher risk of unfavorable outcomes were neutrophilia, lymphopenia, and elevated levels of D-dimer, creatinine, C-reactive protein, or AST. CONCLUSION: A high mortality rate in patients with cancer who were diagnosed with COVID-19 was demonstrated in the present study, emphasizing the need for close surveillance in this group of patients, especially in those with unfavorable prognostic characteristics.

Adjuvant Carboplatin and Paclitaxel Chemotherapy Followed by Radiotherapy in High-Risk Endometrial Cancer: A Retrospective Analysis.

PURPOSE: The best adjuvant treatment in high-risk endometrial cancer remains unclear. Although adjuvant chemotherapy seems to improve overall survival (OS) in locally advanced disease, the role of adding radiotherapy is not certain. We evaluated the outcomes of patients with high-risk endometrial cancer treated with adjuvant chemotherapy followed by radiotherapy. PATIENTS AND METHODS: We performed a retrospective analysis of patients with high-risk endometrial cancer (endometrioid histology stages III to IVA or carcinosarcoma, clear cell, or serous histology stages I to IVA) treated with adjuvant carboplatin and paclitaxel, followed by radiotherapy, from 2010 to 2017 at a Brazilian cancer center. The Kaplan-Meier method was used for survival analysis, and prognostic factors were analyzed using the Cox proportional hazards model. RESULTS: One hundred forty-six consecutive patients were evaluated. The OS rates were 86.2% at 3 years and 75.4% at 5 years. OS was significantly affected by pelvic lymphadenectomy ( P = .001) and positive peritoneal cytology ( P < .001). Three- and 5-year disease-free survival (DFS) rates were 78.3% and 69.5%, respectively. The initial site of recurrence was limited to the pelvis in 4.1% of patients, within the abdomen in 1.3%, and extra-abdominal in 11.6%. Patients with grade 1 or 2 endometrioid carcinoma had better prognosis than patients with endometrioid carcinoma grade 3 or nonendometrioid histology (3-year DFS, 93.67% v 68.5%, respectively; P = .0017). CONCLUSION: Adjuvant carboplatin and paclitaxel, followed by radiotherapy, is effective in high-risk endometrial cancer and associated with low rates of pelvic recurrence, which might be explained by the addition of radiotherapy. The high-risk group is heterogeneous, and the benefit of adjuvant treatment in patients with grade 1 or 2 endometrioid carcinoma is less clear.

Homologous recombination deficiency in ovarian cancer: a review of its epidemiology and management.

Ovarian cancer patients with homologous recombination deficiencies exhibit specific clinical behaviors, and improved responses to treatments, such as platinum-based chemotherapy and poly (ADP-ribose) polymerase (PARP) inhibitors, have been observed. Germline mutations in the BRCA 1/2 genes are the most well-known mechanisms of homologous recombination deficiency. However, other mechanisms, such as germline and somatic mutations in other homologous recombination genes and epigenetic modifications, have also been implicated in homologous recombination deficiency. The epidemiology and implications of these other mechanisms need to be better understood to improve the treatment strategies for these patients. Furthermore, an evaluation of various diagnostic tests to investigate homologous recombination deficiency is essential. Comprehension of the role of homologous recombination deficiency in ovarian cancer also allows the development of therapeutic combinations that can improve the efficacy of treatment. In this review, we discuss the epidemiology and management of homologous recombination deficiency in ovarian cancer patients.

Cystic brain metastases in ALK-rearranged non-small cell lung cancer.

The central nervous system (CNS) is a common site of disease progression in patients with non-small-cell lung cancer (NSCLC) with anaplastic lymphoma kinase (ALK)-rearrangement treated with crizotinib. Cystic brain metastases (CBM) have been recently identified as one possible variant of this disease. An illustrative case report is presented along with a literature review performed in order to track relevant papers about CBM in ALK-rearranged NSCLC, including possible pathophysiology, differential diagnosis and treatment options for this condition. Three case reports have been published describing six ALK-rearranged NSCLC patients presenting with CBM, all of which were under treatment with crizotinib by the time of CBM diagnosis. Treatment with CNS-penetrating tyrosine kinase inhibitors (TKIs) resulted in CNS disease control in three of the six cases reported either as single therapy or in combination with radiation therapy (RT). Investigation of differential diagnoses of CBM might be necessary, which include inflammatory and demyelinating disorders, primary brain tumours and infectious diseases, especially neurocysticercosis that might mimic CBM images. Treatment options include RT, CNS-penetrating TKIs and invasive procedures, such as stereotactic drainage. Thus, CBM are associated with ALK-rearranged NSCLC, particularly in patients who use crizotinib and should prompt investigation of differential diagnosis. CNS-penetrating TKIs are effective in the control of solid brain metastases and also seem to be active in CBM as single therapy or in combination with RT.
