From the Guidelines
The patient with a cough for 3 weeks after finishing chemotherapy for lymphoma 2 months ago should be initially managed with a comprehensive assessment to identify any co-existing causes linked with cough and initiate treatment accordingly, as suggested by the Chest guideline and expert panel report 1. The management of cough in this patient requires careful consideration of the underlying cause, which could be related to the chemotherapy, the lymphoma itself, or other comorbidities.
- Initial evaluation should include a thorough history, physical examination, and appropriate diagnostic tests such as chest X-ray, pulmonary function tests, and possibly CT imaging to rule out serious complications like pneumonia, pulmonary embolism, or cancer recurrence.
- For symptomatic relief, a step-wise approach is recommended, starting with simple measures like adequate hydration and humidification.
- For persistent cough, consider demulcents such as butamirate linctus (syrup) or simple linctus (syrup) or glycerin-based linctus (syrup) as the first line of treatment, as suggested by the Chest guideline and expert panel report 1.
- If the cough does not respond to demulcents, opioids such as pholcodine or hydrocodone (where available) or dihydrocodeine or morphine can be considered, with careful attention to the patient's previous exposure to opioids and the potential for side effects 1.
- The patient should be monitored closely, and severe or persistent cough warrants prompt referral to pulmonology or oncology, as it could indicate serious complications like disease progression or treatment toxicity.
- The management approach should balance symptom relief while investigating and addressing the underlying cause, which is particularly important in this vulnerable population, as emphasized by the American College of Chest Physicians evidence-based clinical practice guidelines 1.

From the Research
Patient History and Presentation
- The patient presents with a cough lasting 3 weeks, having finished chemotherapy for lymphoma 2 months prior, with no upper respiratory infection (URI) symptoms.
- A comprehensive patient history is essential for accurate diagnosis and effective management, as outlined in 2.
- The importance of history and physical examination in diagnosis cannot be overstated, as supported by 3.
Diagnostic Considerations
- Pneumonitis is a potential side effect of chemotherapy, as discussed in 4, and may present with cough among other symptoms.
- Chest radiography is commonly used to identify pneumonia, but its utility can be limited by uncertain results, as shown in 5.
- The role of chest radiographs in diagnosing pneumonia is debated, with some arguing that clinical features alone may be sufficient for diagnosis in mild cases, as discussed in 6.
Management Approach
- Given the patient's history of chemotherapy and presentation with cough, a thorough evaluation for pneumonitis or other pulmonary complications is warranted.
- This may involve chest imaging, such as chest radiography or CT, as well as clinical assessment and laboratory tests, as informed by 4 and 5.
- A comprehensive patient history, as outlined in 2, and physical examination, as emphasized in 3, will guide the diagnostic approach and management plan.
