Cancer care Flashcards
What percentage of patients with advanced cancer experience pain
30-40 percent with early disease
75-90 percent with late disease
65% dying from non-malignant disease experience significant pain
1/3 of patients have 2 or more different pains
Pain can be controlled in 80%
What are the causes of pain in a person with SCC
Cancer related:
- chest wall invasion of cancer
Bone mets
MSCC
Treatment related
- oseophagitis
- local reaction to radiotherapy
Other
- PE
- PNEUMOTHORAX
- CAP
- MI
- Anxiety
- MSK pain
Immune related Colitis guidelines
Radiation mucositis guidelines
Abdominal ascites guidelines
Malignant pleural effusion guidelines
Features
dyspnoea, non-productive cough or chest pain
classic examination findings include dullness to percussion, reduced breath sounds and reduced chest expansion
Imaging
- (PA) chest x-rays
- ultrasound
contrast CT is now increasingly performed to investigate the underlying cause, particularly for exudative effusions
Pleural aspiration
as above, ultrasound is recommended to reduce the complication rate
a 21G needle and 50ml syringe should be used
fluid should be sent for pH, protein, lactate dehydrogenase (LDH), cytology and microbiology
Options for managing patients with recurrent pleural effusions include:
recurrent aspiration
pleurodesis
indwelling pleural catheter
drug management to alleviate symptoms e.g. opioids to relieve dyspnoea
Lights criteria for pleural effusion
Light’s criteria was developed in 1972 to help distinguish between a transudate and an exudate. The BTS recommend using the criteria for borderline cases:
exudates have a protein level of >30 g/L, transudates have a protein level of <30 g/L
if the protein level is between 25-35 g/L, Light’s criteria should be applied. An exudate is likely if at least one of the following criteria are met:
pleural fluid protein divided by serum protein >0.5
pleural fluid LDH divided by serum LDH >0.6
pleural fluid LDH more than two-thirds the upper limits of normal serum LDH
Other characteristic pleural fluid findings:
low glucose: rheumatoid arthritis, tuberculosis
raised amylase: pancreatitis, oesophageal perforation
heavy blood staining: mesothelioma, pulmonary embolism, tuberculosis
