Management of infusion-related reactions in cancer therapy: strategies and challenges. ESMO Open 2024; 9:102922. [PMID: 38452439 PMCID: PMC10937241 DOI: 10.1016/j.esmoop.2024.102922] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 02/06/2024] [Accepted: 02/06/2024] [Indexed: 03/09/2024] Open
Abstract
Several anticancer therapies have the potential to cause infusion-related reactions (IRRs) in the form of adverse events that typically occur within minutes to hours after drug infusion. IRRs can range in severity from mild to severe anaphylaxis-like reactions. Careful monitoring at infusion initiation, prompt recognition, and appropriate clinical assessment of the IRR and its severity, followed by immediate management, are required to ensure patient safety and optimal outcomes. Lack of standardization in the prevention, management, and reporting of IRRs across cancer-treating institutions represents not only a quality and safety gap but also a disparity in cancer care. The present article, supported by recently published data, was developed to standardize these procedures across institutions and provide a useful tool for health care providers in clinical practice to recognize early signs and symptoms of an IRR and promptly and appropriately manage the event.

Chronic obstructive pulmonary disease exacerbations' management in Portuguese hospitals - EvaluateCOPDpt, a multicentre, observational, prospective study. Pulmonology 2022:S2531-0437(22)00155-6. [PMID: 36115826 DOI: 10.1016/j.pulmoe.2022.07.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Revised: 07/15/2022] [Accepted: 07/16/2022] [Indexed: 11/17/2022] Open
Abstract
INTRODUCTION AND OBJECTIVES In order to improve the quality of chronic obstructive pulmonary disease (COPD) patients' care, better knowledge of clinical practice and the factors associated with patient outcomes are needed. This study aimed to evaluate the relation between clinical practice and the outcomes of patients admitted for COPD exacerbations in Portuguese hospitals. MATERIALS AND METHODS Observational, multicentre, prospective study with a 60-days follow-up period, in 11 hospitals, including patients aged ≥ 30 years, admitted to hospital for at least 24 hours due to an acute exacerbation of COPD. Demographic and clinical data were collected, including sex, age, smoking habits, hospitalisations, pulmonary function, comorbidities, COPD symptoms, and treatment. Sixty days after discharge, COPD exacerbations management, outcome measures, and readmission data were evaluated through a structured phone follow-up interview. RESULTS 196 patients were included (85.7% male, mean age 71.2 years), the majority admitted through the emergency service. Ex-smokers and current smokers accounted for 51% and 36%, respectively. On admission, 72.4% were on LAMA, 54.6% on LABA, and 45.5% were on LABA/LAMA. Inhaled corticosteroids (ICS) were used in 37.3% and systemic steroids (SCS) in 10.3%. 35.7 % had had at least one exacerbation, with hospitalisation, in the previous year. There was no spirometry data for 23.2%. On hospitalisation, 98.5% of patients were treated with oxygen and 38.3% with non-invasive ventilation. Additionally, 93.4% used SCS and 60.2% ICS. Antibiotics were administered to 85.2%. 95.4% of patients were discharged; 9 died, 5 of whom had a COPD-related death. The median length of stay was 12 days for discharged patients and 33 days for patients who died. At discharge, 79.1% were prescribed with LAMA, 63.6% SCS, 61.5% LABA and 55.6% LAMA+LABA. 26,2% were prescribed with ICS+LABA+LAMA. At follow-up, 44.4% had a scheduled medical appointment within the 60 days after being discharged, and 28.3% were later readmitted due to exacerbation, of whom 52.8% were hospitalised. CONCLUSIONS The severity of COPD, particularly in exacerbations, is directly related to impaired lung function and quality of life, mortality, and significant health system costs. Knowledge about COPD exacerbations' management in acute hospital admissions in Portugal may help stimulate a national discussion and review of existing data to engage clinicians, policymakers, managers, and patients, raising awareness and promoting action on COPD.

Predictors of immune-related adverse events and outcomes in patients with NSCLC treated with immune-checkpoint inhibitors. Pulmonology 2022:S2531-0437(22)00076-9. [PMID: 35414494 DOI: 10.1016/j.pulmoe.2022.03.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2021] [Revised: 03/14/2022] [Accepted: 03/14/2022] [Indexed: 10/18/2022] Open
Abstract
OBJECTIVE To identify predictors of immune-related adverse events (IRAEs) in patients with non-small cell lung cancer (NSCLC) treated with immune checkpoint inhibitors (ICIs). Assess associations between outcomes and the development of IRAEs. METHODS Retrospective analysis of patients with NSCLC treated with ICIs between 2016 and 2020 in the Pulmonology Department of our hospital. Patients with and without IRAEs were compared. A logistic regression analysis was performed to determine predictors of IRAEs. Progression-free survival (PFS) and overall survival (OS) curves were calculated using the Kaplan-Meier method, and the long-rank test was used to assess survival differences between groups. Univariate and multivariate Cox proportional-hazards regression models were used to identify factors associated with PFS and OS. The value considered statistically significant was p≤0.05. RESULTS A total of 184 patients (77.7% men, mean age 66.9±9.5 years) treated with ICIs were analyzed. During follow-up, 49 (26.6%) patients developed IRAEs and 149 (81.0%) died. According to the multivariate logistic regression analysis, treatment with statins (OR:3.15; p = 0.007), previous systemic corticosteroid therapy (OR:3.99; p = 0.001), disease controlled as response to ICI (OR:5.93; p < 0.001) and higher hemoglobin values (OR:1.28; p = 0.040) were independent predictors for the development of IRAEs. Patients who developed IRAEs had significantly longer medians of PFS (41.0 vs 9.0 weeks, p < 0.001) and OS (89.0 vs 28.0 weeks; p < 0.001). CONCLUSIONS Patients treated with statins, pre-ICI systemic corticosteroids, higher baseline hemoglobin value and controlled disease as initial response to ICI had a higher risk of developing IRAEs. The development of IRAEs was associated with better outcomes.

Abstract
BACKGROUND It is critical to developing an accurate method for differentiating between malignant and benign solitary pulmonary nodules. This study aimed was to establish a predicting model of lung nodules malignancy in a real-world setting. METHODS The authors retrospectively analysed the clinical and computed tomography (CT) data of 121 patients with lung nodules, submitted to percutaneous CT-guided transthoracic biopsy, between 2014 and 2015. Multiple logistic regression was used to screen independent predictors for malignancy and to establish a clinical prediction model to evaluate the probability of malignancy. RESULTS From a total of 121 patients, 75 (62%) were men and with a mean age of 64.7 years old. Multivariate logistic regression analysis identified six independent predictors of malignancy: age, gender, smoking status, current extra-pulmonary cancer, air bronchogram and nodule size (p<0.05). The area under the curve (AUC) was 0.8573. CONCLUSIONS The prediction model established in this study can be used to assess the probability of malignancy in the Portuguese population, thereby providing help for the diagnosis of lung nodules and the selection of follow-up interventions.

Abstract
SUMMARY We describe the case of a 56 year-old woman with the almost simultaneous appearance of diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) and a carotid body paraganglioma. Of interest, 6 years earlier, the patient underwent total thyroidectomy due to papillary thyroid carcinoma and, in the meantime, she was submitted to mastectomy to treat an invasive ductal carcinoma of the breast. In order to explain these lesions, an extensive genetic study was performed. Results showed positivity for the presence of the tumor suppressor gene PALB2, whose presence had already been detected in a niece with breast cancer. The patient underwent different procedures to treat the lesions and currently she is symptom-free over 2 years of follow-up. LEARNING POINTS The presence of two rare neoplasms in a single person should raise the suspicion of a common etiology. To the best of our knowledge, this is the first case that shows the coexistence of DIPNECH and paraganglioma. The contribution of the PALB2 gene in the etiology of these rare neoplasms is a possibility.

Abstract
OBJECTIVES To characterise the morbidity of COPD out-patients based on symptoms, acute exacerbations, FEV1 and comorbidities, and to explore the association between different patients' characteristics such as social, demographic, clinical history or exposure. METHODS Stable COPD outpatients over 40 years old diagnosed according to GOLD criteria were included consecutively; the exclusion criteria were only refusal to participate and inability to understand clinical questionnaires. A survey of demographic and clinical data was conducted. Symptoms were evaluated using the CAT and mMRC questionnaires. The number of COPD acute exacerbations reported in the previous year was assessed, and spirometry performed on all participants according to ATS/ERS recommendations. Different variables were collected and then related to each other. RESULTS We studied 303 COPD outpatients, all Caucasians, 79.5% males and mostly elderly. 65.7% of participants reported having low monthly income and 87.8% a low education level. Tobacco smoking was the most common exposure identified but a substantial proportion of COPD patients were non-smokers (26%). Frequent acute exacerbations were reported by 38.0% of patients. The mean post-bronchodilator FEV1 was 53.2%. The distribution of patients according to GOLD 2017 stage and classification was respectively 9.9%, 41.9%, 35.0% and 13.2% from 1 to 4 and 23.1%, 39.6%, 2.3% and 35.0% from GOLD A to D. Only 29 patients (9.5%) presented no comorbid conditions, and the most common were hypertension, heart diseases and dyslipidaemia. CONCLUSIONS Our data confirms COPD as a complex and heterogeneous disorder, with a significant morbidity due to the nature of symptoms, frequent comorbidities and exacerbations. A substantial proportion of COPD patients were never-smokers, mainly women, calling attention to the need for COPD recognition in these cases. COPD in women, in never-smokers and in patients with a previous diagnosis of asthma presented some specific characteristics. Some patient characteristics are associated with frequent acute exacerbations. FEV1 was strongly related both to symptoms and exacerbations.

COPD: misuse of inhaler devices in clinical practice. Int J Chron Obstruct Pulmon Dis 2019; 14:1209-1217. [PMID: 31213798 PMCID: PMC6549399 DOI: 10.2147/copd.s178040] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2018] [Accepted: 10/25/2018] [Indexed: 01/08/2023] Open
Abstract
Background and objectives: Inhalers mishandling remain an important clinical issue worldwide. The aim of this study was to evaluate inhalation technique in stable COPD out-patients. The variables under study were type of inhaler device (ID), patients’ preference for an inhaler, number of IDs used by each patient, beliefs about inhaler medication and some demographic, clinical and functional patients' characteristics. We aim to assess how they are related to inhalation technique. Methods: A cross-sectional study was conducted in a hospital outpatient respiratory care. COPD patients over 40 years old, diagnosed according to GOLD criteria, and using IDs were included consecutively. The Beliefs about Medicines Questionnaire (BMQ), a demographic and a clinical survey were applied. The number of IDs used by each patient and the patients’ preference for some IDs were recorded. Patients were asked to demonstrate the use of their prescribed inhalation devices, and inhaler technique was assessed by using previously defined checklists, including essential steps and critical errors. A statistics analysis was then performed. Results: We studied 300 subjects performing a total of 521 inhalation manoeuvers with 10 different IDs. At least one step incorrectly performed was found in 48.2% of demonstrations and in 29.9% critical errors were observed. Misuse was related to priming/loading in 6.9%, to inhalation manoeuver in 13.1% and to both in 10%. There was a statistically significant association between critical errors and type of ID (P<0.001). No significant relationship was found between correct performance of key manoeuvers and patients’ preference or number of inhalers used per patient. Misuse due to critical errors was observed in 39.3% of patients and was positively related to female gender, age ≥65, lower education level and lower socioeconomic status (higher Graffar classification score), but not to patients’ clinical or functional characteristics. In the sub-group of patients presenting critical errors when using IDs, there was a statistically significant inverse association between BMQ Necessity score and number of critical errors. Conclusions: Inhalers mishandling remains disappointingly common. A good inhalation technique depends on the type of ID, and failure of inhalation manoeuver was the main cause of ID misuse. It was not associated to multiple inhalers’ use nor to patient’s preference, but to the patient’s beliefs about the necessity to use them. Elderly patients, women and those with lower education level or lower socioeconomic status demonstrate a worse inhalation technique.

Abstract
INTRODUCTION Lung cancer is the deadliest cancer worldwide. In Portugal, the disease remains the main cause of cancer death in males. AIM This study aims to evaluate the demographic and clinical characteristics of lung cancer patients diagnosed and treated in northern Portugal hospitals from 2000 to 2010. PATIENTS AND METHODS Twelve hospitals in the north of Portugal contributed to this study. The demographic and clinic characteristics of the patients registered in each hospital from 2000 to 2010 and the patterns of their occurrence were analyzed. RESULTS During an 11-year period (2000-2010), 9767 lung cancer patients were registered in the participating hospitals. Comparing the number of the patients registered in the year 2000 to those registered during 2010, there was a significant increase in lung cancer cases. Females represent only 20% of the total registered lung cancer cases; however, during the study period, the number of female patients increased by 30%. A significant number of the patients, 3117 (48.6%), had poor performance status at presentation. The adenocarcinoma histology became more preponderant over the study period. Most of the patients were diagnosed as stages IIIB or IV: 7206 of 9267 (77.8%). Chemotherapy was the treatment of choice for 3529 (40.4%) patients, whereas surgical treatment was achieved in 1301 (14.9%) cases. CONCLUSION A significant number of lung cancer patients have been diagnosed and treated in hospitals in northern Portugal, and the incidence of the disease among females has been increasing. The overwhelming majority of the tumors were diagnosed in advanced stage; nevertheless, surgical treatment was possible in 14.9% of the patients.

Abstract
INTRODUCTION Integrated PET/CT has become a fundamental tool in the preoperative assessment of non small lung cancer (NSCLC) providing useful anatomical and metabolic information to characterize tumoral lesions and to detect unsuspected metastatic disease. AIM To compare the agreement between clinical and pathological staging before and after the use of PET/CT. MATERIAL AND METHODS Retrospective study of patients with NSCLC who underwent potentially curative surgery throughout 10.5 years. Cohen's kappa coefficient was used to evaluate staging agreement. RESULTS One hundred and fifty patients were evaluated, 78% males, with a mean age of 65 (±9.6) years. Thirteen percent were submitted to neoadjuvant chemotherapy. PET/CT was performed in 41%. Global agreement between clinical and pathological staging was 51% (kappa=0.3639). There was a statistically significant difference between the staging results in patients who underwent PET/CT, when compared to the subgroup who did not (p=0.003). For those with PET/CT false negatives occurred in less 39%, false positives in more 12% and clinical and pathological staging coincided in more 27%. The overall results reflected an improvement in the agreement between clinical and pathological staging in the PET/CT subgroup (67%, kappa=0.5737 vs 40%, kappa=0.2292). PET/CT accuracy was enhanced when patients re-staged after neoadjuvant therapy were excluded and a substantial staging agreement was obtained for those who had the exam only for staging purposes (73%, kappa=0.6323). CONCLUSION Inclusion of PET/CT in NSCLC preoperative assessment improved the accuracy of the clinical staging, with a good level of agreement with pathological staging.

Abstract
The Portuguese Journal of Pulmonology is progressively achieving an important status in Portuguese medical literature. The present editors thought it would be an enriching task to revise the main topics published during 2009. The invited members of the Editorial Board covered and commented the most relevant articles and gave us an important picture of the quality of the science it was published in Portuguese Pulmonology.

Abstract
Lung cancer (LC) staging remains a clinical challenge as it determines the disease's prognosis and treatment. Surgery is the best option for controlling non-small cell lung cancer (NSCLC) and the only potential cure. In this setting, lung cancer staging helps select patients who will benefit from surgery, excluding inoperable patients and including patients with resectable lesions. The aim of this study is to compare clinical staging (TNMc) with pathological staging (TNMp) and to evaluate diagnosis, complementary treatment and survival of these patients. This is a retrospective study that included patients with non-small cell lung cancer or with highly suspicious lesions who had undergone surgery and were followed up in the Hospital de São João lung cancer unit between January 1999 and December 2003. It is based on clinical files and pathology reports. 73.3% of this group of 60 patients were male, with median age 59.2 years. The most frequent TNMc stages were 41.7% T1N0M0 and 36.7% T2N0M0. Thoracotomy for therapeutic purpose was per- formed in 80% and thoracotomy for diagnostic purpose also in the remaining 20%. In 6.7% the resection was incomplete. The most frequent TNMp stages were T2N0p in 33.3%, T2N1p in 15.0% and T2N2p in 13.3%. There was a significant difference between the two staging types, with upstaging in 65.0%, down staging in 67% and only 28.3% keeping the same stage. The most frequent differences were from T1N0c to T2N0p and from T2N0c to T2N1p. The global agreement between both staging methods was 21.7%. Median global survival was 43 months. In conclusion, while clinical staging was less accurate, it did not determine important changes in therapeutic strategy and survival. For the future, we should consider using other diagnostic tools and other biological factors to complement the anatomical information that we currently use.

Abstract
The authors describe the case of a man, 46 years old, former smoker, former bird breeder, followed in the service of Imunoallergology for bronchospasm without response to the treatment. After experiencing an hemoptysis he was admitted in our service. He was submitted to many exams, which include a flexible bronchoscopy. This technique allows the identification of an endobronquial necrotic mass, which almost obstructed the main right bronchus. In order to obtain a bigger and more representative sample a rigid bronchoscopy was performed. This technique showed a broncholith, which was partially removed, and a bronchial fistula. Actually he is assimptomatic and under annual surveillance. First described for Aristoteles, the broncholithiasis is defined by the presence of stones in the bronchial tree. It is a very rare pathology, with a variable clinical expression, which must be considered whenever there is respiratory complaints in association with hilar or mediastinic calcifications.

Abstract
The authors studied the influence on survival of 21 clinical, anatomical, haematological and biochemical factors evaluated, at diagnosis, of 411 patients (pts) with advanced Non Small Cell Lung Cancer (NSCLC) followed in our department between 1984 and 1990. Most of the patients were male (347--84.4%) and only 64 (15.6%) were females. Median age was 62 years, but was slightly higher in females. Only 34 patients were aged under 45 years. Squamous cell carcinoma (215 pts--52%) and adenocarcinoma (152 pts--37%) were the most frequent histologic types. Performance status was poor--only 103 (25%) continued active; 120 (29%) spent at least half of the time in bed; 188 (46%) were severely limited. After staging, 179 (44%) presented locally advanced disease (stage IIIB) and 232 (56%) metastatic dissemination (stage IV). Therapy was defined by the oncologic group according to individual characteristics and based on clinical grounds. Anti-neoplastic therapy was performed in 225 (55%), chemotherapy alone in 121 (30%), radiation therapy alone in 67 (16%), and sequential combined treatment (chemotherapy and thoracic radiation) in 37 (9%). Until 1987, the main chemotherapy regimen was MACC (Metrotrexate + Adriamycine + Cyclophosphamide + Lomustin), afterwards VP(M) (Cisplatin + Vimblastin + Mitomycine). Radiation therapy was performed using Co60, 2 Gy/day, 5 days a week, for 4 weeks (approximately 45 Gy total). The response rate was poor--four complete responses (2%), 42 (19%) partial responses. The overall median survival was 4.3 months and only 5% of patients were alive after 18 months of follow up. Prognostic importance of each characteristic studied was initially done by unifactorial analysis, followed by multifactorial analysis according to two methods: Cox proportional hazards model and recursive partitioning amalgamation--RECPAM. Regardless of the method used, the main determinants of survival were found to be performance status (Zubrod), weight loss and serum albumin. Other factors such as the staging (presence or absence of metastasis), lymphocytes, lactic dehydrogenase, and hoarseness were also significant. It is noteworthy that age and histological type were irrelevant; sex and hoarseness only proved important when integrated within a multifactorial model. The overall prognostic evaluation and therapeutic decision of advanced NSCLC patients could be improved by combining the prognostic value of TNM with that of performance status, weight loss and serum albumin. These prognostic guidelines must be taken into account when designing new clinical trials.

Abstract
It is possible that asthma epidemiology will contribute to the definition of asthma precipitant factors. This work is enrolled in an international study co-ordinated by COMAC-EPI. In Oporto, among 137.000 residents in the same town region, a standardised sample of 4.047 male and female individuals aged from 20 to 44 years was defined. A screening questionnaire was sent with a stamped envelope. Four months later the same questionnaire was sent to the individuals who did not answer it and finally those who do not answer the second letter were visited in their own residence. We got 2075 answers. Among the responders about half were women: 1075, 25.39% belonging (273) to the 20-29 years age group; 42.69% (459) 30-39 years; 31.90% (343) 40-44 years. In men the percentage of distribution by age groups was similar. Question nQ 5 was answered affirmatively by 60 individuals, corresponding to the prevalence of 2.89%. Seventy-one (3.42%) said they had been under asthma treatment during the last year. Among the symptoms that usually define the attack of asthma, those inquired in the group of question 1 show a prevalence close to that of the asthma diagnosis: 6.45%. The prevalence of being awakened by tightness in the chest, shortness of breath and coughing, with values of 16.17%, 10.69% and 25.68% is quite superior than in question nQ 5. The prevalence obtained with the Hay Fever question was 18.84%. Data obtained is similar to the data of other centers.

Abstract
The Forced Expiratory Volume in the 1st second (FEV1) and the Forced Vital Capacity (FVC) was determined before and after a hemodialysis (HD), in 61 patients suffering from chronic renal failure (CRF). Before and after the same HD the value of the following parameters were determined: Na; K; Cl; Urea; Creatinine, Ca; P and hematocrit. We found the following values: initial FEV1 91.68%, final FEV1 100.35%, (P less than 0.001); initial FVC 87.4%, final FVC 95.87% (P less than 0.001). The 61 patients were separated in two sub-groups. In the first the FEV1 variation less than or equal to 8%, while in the second it was greater than 8%. The mean variation of the other parameters was determined in both sub-group. No significant difference was found between them. On the other hand a significant correlation was found (r = 0.06, P less than 0.03) between the improvement of pulmonary function and the ponderal loss. The correction of the hydrosaline overload seems to be an important factor in the reported spirometric improvement.
