Chronic cough and sputum for at least three months per year was associated with excess risk only if their duration was less than two years before diagnosis of lung cancer and, therefore, they were suspected of being more likely early symptoms of preclinical lung cancer rather than its cause.

D Anderson Symptom Inventory before and after their first chemotherapy cycle, apparently it does have. Prognostic values of baseline symptoms and changes in symptom severity were examined by Cox proportional hazard models.
The conclusion of the study was that patients with advanced non-small cell lung cancer during their first line chemotherapy cycle experienced moderate to severe coughing or increased fatigue or shortness of breath, indicating an increased risk for shorter survival.

The significance of cough in palliative care setting Cough is a complex physiological mechanism that protects the airways and lungs by removing mucus and foreign matter from the larynx, trachea and bronchi. The expulsion is made possible by the high intrathoracic and high airflow velocity generated during the cough reflex 5.
In literature, cough is classified as: productive cough in a patient able to cough effectively; productive cough in a patient not able to cough effectively; nonproductive cough. In order to be effective, these conditions are required: optimal function of the respiratory muscle, closure of the glottis, dynamic compression of the major airway, favourable mucus properties, effective mucocilliary clearance 5. However, patients in palliative care, due to multiple unfavourable factors, may not be able to generate forceful cough Cancer prostate : symptômes phase terminale 1.
The pathophysiology of cough - neuroanatomy and cough reflex The cough receptors are widespread in the tracheobronchial tree, but the highest density is in the larynx, trachea and main bronchi.

The receptors are also located in the nose, pharynx, paranasal sinus, ears, pleura, diaphragm and pericardium. The cough receptors are stimulated by mechanical stimulus pressure, deformation, touchand chemical stimulus smoke, mucus, endogenous chemical mediators.

Impulses travel via the internal laryngeal nerve, a branch of the superior laryngeal nerve which stems from the vagus nerve to the medulla of the brain, that represents the afferent neural pathway. The efferent neural pathway begins with the signals transmitted from the cerebral cortex and medulla via the vagus nerve and superior laryngeal nerves to the glottis, external intercostals muscles, diaphragm and other inspiratory and expiratory muscles.
The mechanism of cough is as follows 12 : first, it starts with a deep and rapid inspiratory effort; diaphragm innervated by the phrenic nerve and external intercostals muscles innervated by segmental intercostals nerves contract, creating a negative pressure around the lung; air rushes into the lungs in order to equalize the pressure; the glottis closes muscles innervated by recurrent laryngeal nerve and the vocal cords contract to shut the larynx; the abdominal muscles contract to accentuate the action of the relaxing diaphragm; this increases the pressure of air within the lungs; the vocal cords relax and the glottis opens, releasing air at over mph; the bronchi and non-cartilaginous portions of the trachea collapse to form slits through which the air is forced; this clears out any irritants attached to the respiratory lining.
Causes of cough in cancer patients Infections of the respiratory tract and chronic obstructive pulmonary disease at a smoker patient with lung cancer are frequently encountered in clinical practice. Immunocompromised patients are likely to develop invasive pulmonary aspergilosis. Cough associated with upper respiratory tract infection might be elicited by a voluntary cortical pathway with the sensation of cancer prostate : symptômes phase terminale irritation acting as a trigger 7. There are also several complications of lung cancer which give rise to increased coughing, like pleural or pericardial effusion, bronchopleural fistula, lymphangitis carcinomatosa, or superior vena cava obstruction.
The mechanism of dry non-productive cough in pleural effusion is not completely understood, but apparently the lung compression by the fluid may bring opposing bronchial walls into contact, stimulating cough reflex.

Cough is a side effect of ACE inhibitors that cause increased levels of bradykinin which may be the cause of hyper reactivity of the cough reflex. Busulfan-based chemotherapy used in autoloug peripheral blood stem cell transplantation causes acute or subacute idiopathic pneumonia syndrome, a condition characterized by cough and pulmonary infiltrates, and hypoxemia. Anticancer drugs and radiotherapy are associated with pulmonary fibrosis manifested by persistent cough.
Phase I study of paclitaxel as a radiation sensitizer cancer prostate : symptômes phase terminale the treatment of mesothelioma and non-small cell lung cancer was initiated to determine the maximum tolerated dose and dose limiting toxicities of paclitaxel with concurrent thoracic irradiation. Six patients had grade 2 lung injury manifested by a persistent cough that required antitussives 8.
Radiation therapy may lead to hypersensitivity pneumonitis and lymphocytic alveolitis, according to an article about lung toxicity following chest irradiation in patients with lung cancer.

It promotes aspiration which may lead to a cough reflex and may be associated with pneumonia The diminished cough reflex was the result of a disordered epiglottal and pharyngeal muscle coordination that delayed cough and was ineffective in expectorating the aspirated material.
Mediastinal encroachment of a bronchial cancer or simply during thoracic surgery for lung cancer, or unilateral vocal cord paralysis can lead to reduced cough effectiveness. Imaging can be also useful to identify the cause of cough: X-ray, CT scan or ultrasound in case of suspected pleural or pericardial effusion.
According to latest studies, bronchoscopy may be indicated to complete the assessment of cough in non-smokers with normal chest radiograph to diagnose bacterial suppurative disease and other non-malignant airway disease.
Avant une FIV, 7 choses à savoir
However, a patient who smokes cigarettes, who has a new cough, or a changing character of the cough that persists for months should have a bronchoscopic examination even when the chest radiograph findings are negative Dyspnea accompanies cough: if it is an intraluminal airway tumour, it will stimulate cough receptors and obstruct airflow to produce dyspnea; if it is an extraluminal tumour compression of a large airway, it may not associate cough, however the obstruction of the airway may lead to post-obstructive pneumonia that accentuates cough.
Management of cough in cancer patients 6.
Radiation therapy One of the primary purposes of the radiotherapy is palliation of symptoms. One of the studies on this subject had the objective to investigate the changes in respiratory symptoms and quality of life in patients with locally advanced and metastatic non-small cell lung cancer receiving radiotherapy.
Assessments were performed before radiotherapy and two weeks, six weeks and three months after radiotherapy. In the last few years, there has been a tendency to use a continuous hyperfractionated radiotherapy and focused on the outcome on long term treatment. The randomized multicentre trial of continuous hyperfractionated accelerated radiotherapy versus conventional radiotherapy in patients with head and neck cancer on a total of patients showed that there were significantly worse symptoms of cough and hoarseness at six weeks in those treated conventionally After examining ten published randomized trials of palliative lung cancer from Cochrane databased, it was concluded that there was no regime that gave better symptom resolution and the patients should be treated with the minimum dose in one or two fractions hypofractination.
When lung cancer recurs after a course of radiotherapy, it is possible to offer a second course of radiotherapy.
Chemotherapy Gemcitabine- and cisplatin-based combinations chemotherapy has concentrated on specific symptoms including cough. A study in poor prognosis performance status 2 of non-small cell lung cancer patients comparing combination chemotherapy carboplatin and paclitaxel versus single agent therapy gemcitabine or vinorelbine showed that a good palliation of symptoms was achieved median time to progression was 4.
