This randomized clinical study aims to assess whether prophylactic treatment with inhaled steroids in patients with locally advanced or concomitantly treated non-small cell lung carcinoma who are candidates for combination treatment with QT/RT or IMT + QT/RT.
The main questions it aims to answer are:
Whether prophylactic treatment decreases the severity of NPR on CTCAE v4.0 and RTOG scales.
Whether inhaled steroid use modifies the response to radiation therapy treatment compared to patients who do not receive prophylactic inhaled steroids.
Patients with non-small cell lung cancer (NSCLC) with unresectable locally advanced or metastatic disease (IIIA, IIIB or IV) of the classification tumor node, metastasis (TNM) of malignant lung tumors, 7th edition.
NSCLC patients candidates for concomitant treatment (chemotherapy plus radiotherapy or target therapy plus radiotherapy).
Evidence of measurable disease
Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2, Karnofsky 70-100.
Unstable systemic disease: active infection, heart, liver, kidney or metabolic disease; including uncontrolled chronic lung disease.
Patients treated with systemic or inhaled corticosteroids.
Patients of reproductive age without a family planning method, pregnant or lactating.
Previous diagnosis of Pneumonitis with toxicity grade ≥ 2 by CTCAE v4.0 or RTOG scale.
Parallel
Inhaled budesonide
DrugPatients will use inhaled budesonide (Numark) with space chamber at 400 mcg given twice daily initiating after the first dose of RT and continuing until pneumonitis development or 12 months completed.
Pneumonitis graded by the Common terminology criteria for adverse event v4.0. (CTCAE v4.0).
Current score for radiation pneumonitis according to symptoms and radiographic changes. Grade 0: No changes, Grade 1: Asymptomatic or mild respiratory symptoms, Grade 2: Moderate respiratory symptoms of pneumonitis (a severe cough) and radiographic changes (radiographic patches), Grade 3: Severe respiratory symptoms of pneumonitis, dense radiographic changes. Grade 4: Symptoms of acute respiratory failure requiring assisted ventilation or continuous oxygen. Grade 5: Death directly related to late effects of radiotherapy.
Pneumonitis graded by the Radiation Therapy Oncology Group score (RTOG)
Current score for radiation pneumonitis according to symptoms and radiographic changes. Grade 0: No changes, Grade 1: Asymptomatic, only radiological or tomographic findings, Grade 2: Symptomatic, does not interfere with daily activities, Grade 3: Symptomatic, interferes with daily activities, requires supplemental oxygen. Grade 4: Threatens life, needing ventilator support. Grade 5: Severe pneumonitis with fatal outcome.
Lung cancer-associated symptoms assessment
Symptoms are evaluated with the supplementary lung cancer-specific questionnaire of the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (validated Mexican-Spanish version). It comprises 13 questions related to the assessment of dyspnoea, pain, coughing, sore mouth, dysphagia, peripheral neuropathy, alopecia, and hemoptysis. The items scale ranges from 1 (Not at all) to 4 (Very much). The average of the items that contribute to the scale (raw score) is estimated and transformed so that scores range from 0 to 100. A higher scale score represents a higher level of symptoms.
Treatment-related side effects in lung cancer
Symptoms are evaluated with the supplementary lung cancer-specific questionnaire of the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (validated Mexican-Spanish version). It comprises 13 questions related to the assessment of dyspnoea, pain, coughing, sore mouth, dysphagia, peripheral neuropathy, alopecia, and hemoptysis. The items scale ranges from 1 (Not at all) to 4 (Very much). The average of the items that contribute to the scale (raw score) is estimated and transformed so that scores range from 0 to 100. A higher scale score represents a higher level of side-effects.
Cognitive functioning evaluated by the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire
The cognitive functioning is evaluated using the validated Mexican-Spanish version of the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaires. It comprises two questions related to the assessment of short and long-term memory. The items scale ranges from 1 (Not at all) to 4 (Very much). The average of the items that contribute to the scale (raw score) is estimated and transformed so that scores range from 0 to 100. A higher scale score represents a healthy level of functioning.
Emotional Functioning evaluated by the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire
The Emotional Functioning is evaluated using the validated Mexican-Spanish version of the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaires. It comprises four questions related to the assessment of depression, anxiety, irritability, and stress. The items scale ranges from 1 (Not at all) to 4 (Very much). The average of the items that contribute to the scale (raw score) is estimated and transformed so that the scores range from 0 to 100. A higher scale score represents a represents a healthy level of functioning.
