Serological response to COVID-19 vaccination in patients with cancer older than 80 years.

Central studies carried out on vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-COV2) excluded patients receiving immunosuppressive therapy and those diagnosed with an immunosuppressive condition. Moreover, there are no data on vaccine efficacy regarding older patients with cancer. OBJECTIVES: The primary objective was to evaluate the seroprevalence of the SARS-CoV2 IgG in older patients (aged ≥80 years) diagnosed with solid or hematological malignancies, one month after administering the second dose of the BNT162b2 vaccine. MATERIALS AND METHODS: We screened 74 older patients with cancer, 45 of them accepted to receive the vaccination and collected serum samples from 36 patients; a group of medical doctors and nurses from our hospital was used as a control in a 1:2 ratio. RESULTS: The median age was 82 years (range 80-89). Median serum IgG were 2396,10 AU/ml (range 0-32,763,00) in patients with cancer and 8737,49 AU/ml (398.90-976,280,00) in the control group, p < 0.0001. Additional subgroup analyses were performed comparing males and females, patients treated with chemotherapy versus other therapies (immunotherapy, targeted therapy), solid tumors versus hematological malignancies, early (I-II) versus advanced (III-IV) stage of disease, continuative corticosteroid use or not. None of them reached statistical significance. CONCLUSION: Our study shows for the first time that patients with cancer aged ≥80 years can have a serological response to the BNT162b2 COVID-19 vaccine one month after vaccination and consequently support the vaccination campaign currently underway in this frail population.

Interventions to Reduce Neurological Symptoms in Patients with GBM Receiving Radiotherapy: From Theory to Clinical Practice.

BACKGROUND: Patients affected by glioblastoma often develop cerebral oedema as a life-threatening complication. Although there is no approved pharmacological intervention, such cerebral oedema is usually treated with dexamethasone. Dexamethasone has been shown in experimental studies to reduce cerebral oedema with only few mineralocorticoid side-effects. The goal of our study was to examine its efficacy in reducing the emergence of neurological deficits during the Stupp protocol. PATIENTS AND METHODS: We studied a retrospective cohort of 459 patients, assigned in controlled groups: in group A, patients received radiochemotherapy followed by adjuvant chemotherapy; in group B, patients received an equivalent combined treatment with dexamethasone. RESULTS: The frequency of neurological symptoms was significantly lower in dexamethasone-treated patients. CONCLUSION: Early diagnosis and prevention of cerebral oedema are important because functional consequences can be anticipated with an appropriate medical treatment. Thus, our study reveals that dexamethasone acts to prevent the appearance of neurological symptoms in patients with brain tumour.

Brain Metastases: Surgical Treatment and Overall Survival.

BACKGROUND: Brain metastases occur in 10%-40% of patients with cancer and are more common than primary brain tumors (30%-40%); their incidence is growing because of improvements in control of systemic disease, better radiologic detection, and prolonged survival. Modern treatment of brain metastases has dramatically changed the expected prognosis. Traditionally, the prognosis has been considered very poor, and patients were referred to palliative treatment because of their terminal stage; however, new prognostic indexes have been proposed to evaluate these patients. The aim of our study was to determine the long-term effect of surgery on overall survival (OS) in patients with brain metastases from dissimilar primary tumors and to identify prognostic variables associated with prolonged survival. METHODS: We retrospectively reviewed a consecutive series of patients who underwent surgery between January 2010 and October 2014 for cerebral metastases from lung, kidney, breast, and gastrointestinal cancers and melanoma. Variables included age; sex; histology; location of lesions; and specific treatments patients had undergone including chemotherapy, radiotherapy, and surgery, individually or combined. RESULTS: No patients deteriorated after surgery. At discharge, 19 patients (26.76%) had an unchanged postoperative neurologic examination, whereas 52 patients (73.23%) showed improvement (χ2 = 34.84, P < 0.0001). Expected OS, considering all tumor subtypes, was 372.24 months; the patients in our series had an OS of 787 months, more than twice the expected OS; specifically, average expected survival of each patient was 5.24 months, whereas actual survival was 11.08 months (P = 0.000008). CONCLUSIONS: Surgery is a safe and effective procedure for cerebral metastases and should not be considered an aggressive treatment in such disease. In our series, 55% of patients had a survival >6 months and a significant improvement in terms of actual versus expected survival. Surgical resection should be considered the primary option for patients with brain metastases.

A metronomic schedule as salvage chemotherapy for upper gastrointestinal tract cancer.

In recent years, metronomic chemotherapy, consisting of continuous administration of low doses of cytotoxic agents, has being used as rescue therapy for different tumours. The aim of this study was to retrospectively assess the efficacy and safety of low-dose metronomic, oral capecitabine in pretreated or frail patients with recurrent upper gastrointestinal tract cancer. Patients with pretreated upper gastrointestinal tract cancer or who were not candidates for standard chemotherapy because of toxicity concerns received capecitabine at 1500 mg per day continuously until disease progression or occurrence of toxicity. Forty-seven patients (25 oesophagogastric cancer, 22 pancreatobiliary cancer; 25 men, 22 women; median age 69 years, range 42-90) were included in the study. Forty-five percent of the patients had received at least two previous lines of treatment and the median number of previous treatments was 1 (range 0-5). Twelve (31.6%) patients achieved clinical benefit (one partial response, 11 stable disease), whereas nine (23.7%) patients were progression free for at least 6 months. In an exploratory analysis, there was a significant relationship between performance status and clinical benefit (hazard ratio=8.25; P=0.01). The median overall survival was 5 months. A good performance status was associated with a longer survival (hazard ratio=0.26; P<0.01). No severe toxicity or treatment-related death was reported. Metronomic capecitabine showed good safety and moderate activity in frail or pretreated patients with advanced, upper gastrointestinal tract cancer.
