The role of clinical examination throughout disease evaluation

The role of clinical examination throughout disease evaluation
as during all cancer patients, the clinical examination may be a crucial
part of the initial analysis of patients presenting with
sclc. a thorough patient history is vital to evaluate for
native, regional, and systemic symptoms of cancer as listed in
the previous sections. the clinical examination could reveal additional
abnormal findings within these patients who most frequently
present with advanced disease at the time of diagnosis. the initial
approach to the physical examination in sclc patients includes
a general assessment of the patient and his or her overall
well-being and performance standing. most patients with sclc
do present with physical symptoms, which regularly cause a
modification during a patient’s general appearance. the general examination
could reveal cachexia related to weight loss, and may
too reveal changes in skin tone or color characteristic of the
anemia typically present in patients with advanced disease ( or the
plethora seen in patients with emphysema ). vital signs are another
vital part of the examination as a result of patients
could have developed abnormal heart rates or rhythms based
on systemic illness or involvement of the cardiopulmonary
system. specifically, resting tachycardia is common in patients
with underlying hypoxia. patients may additionally  exhibit postural
hypotension connected to poor oral intake leading to dehydration.
fever is related to postobstructive pneumonia,
and tachypnea may be a typical finding as a result of several patients have
pulmonary compromise from their cancer or underlying pulmonary
disease.
the physical examination of the pinnacle and neck region
in patients with sclc will facilitate detect spread to the current region
and associated abnormalities. subcutaneous metastasis can
occur within the scalp, and therefore these is demonstrated on physical
examination by observation and palpation. during addition,
cervical or supraclavicular, or maybe occipital lymphadenopathy
is related to locally advanced or metastatic sclc.
svc syndrome could reveal neck vein distension or facial or
periorbital swelling during this region yet. cranial nerve abnormalities
is related to cns disease, meningeal
carcinomatosis, or sympathetic nerve involvement with the
occasional little cell cancer affecting the superior sulcus producing
horner syndrome.
the pulmonary examination is crucial in evaluating patients
with lung cancer. native consolidation from mass effect
or atelectasis will occur and sometimes shows different specific findings
like pneumonia leading to crackles, rhonchi, wheezing, or
dullness to percussion. sclc will too manufacture pleural effusions
demonstrated by dullness to percussion and decreased
breath sounds. pleural involvement could cause a pleural friction
rub. most patients with sclc have a history of heavy
tobacco exposure and could thus demonstrate changes
related to copd like wheezing and decreased air
movement.
cardiac examination in sclc patients could reveal tachyarrhythmias
like sinus tachycardia or atrial fibrillation if pericardial
disease ( or pulmonary hypertension ) is present. the
cardiac examination could reveal a friction rub consistent with
pericarditis or a pericardial effusion. pulmonary artery hypertension
will too accompany lung cancer, and a right ventricular
heave could be identified on physical examination.
examination of the bones as well as spine could reveal
areas of tenderness consistent with bony metastatic disease.
less typically observed in little cell histology is digital clubbing
or hypertrophic pulmonary osteoarthropathy ( hpoa ), with
tenderness of the bones of the lower extremities, a lot of characteristic
of non–small cell carcinoma.
careful examination of all lymph node stations is important
in patients with sclc attributable to the proclivity of this
disease to metastasize to lymph nodes. the palpable regions
most commonly concerned are the cervical and supraclavicular
lymph node chains. enlarged axillary lymph nodes may additionally  be
detected. inguinal lymph nodes are less commonly concerned,
other then when present, they indicate disseminated stage iv disease.
the abdominal examination could demonstrate liver, adrenal,
or intraperitoneal metastases. little cell carcinoma can
too spread to the periportal or pancreatic region. examination
could show hepatomegaly or abdominal fullness consistent with
abdominal metastasis. ascites will develop in patients with
metastatic sclc connected to intra-abdominal tumor or liver
disease and manufacture abdominal distension.
the extremity examination in patients with nsclc can
show digital clubbing, other then this occurs less commonly in small
cell histology. different abnormalities within the extremity examination
will embody wasting of the muscles, fingernail changes, or
cyanosis within these patients.
skin examination could show changes in patients with
sclc, as well as pallor related to anemia, skin rashes
that could be paraneoplastic in nature, or jaundice associated
with liver dysfunction ( or often hemolysis ). little cell
carcinoma will too spread to the skin or subcutaneous tissues,
manufacturing symptomatic or asymptomatic nodules.
the neurologic examination requires significantly careful
attention in sclc patients. numerous manifestations will include
dementia, changes in mental standing, weakness ( focal or
diffuse ), loss of sensation, cerebellar findings like ataxia,
loss of coordination and gait disturbances, and cranial nerve
abnormalities. these findings want to be viewed within the context
of the overall clinical situation to create an appropriate
diagnosis and direct any analysis and treatment. a
careful neurologic examination helps to evaluate for cns
involvement from metastatic tumor or paraneoplastic neurologic
effects. neurologic consultation is typically helpful as are
imaging studies like ct or mri scans, and electromyogram
( emg )/nerve conduction velocity ( ncv ) studies in
localizing the lesion and narrowing down the differential diagnosis
of neurologic abnormalities. serum and cerebrospinal
fluid antibodies could be helpful in suspected p araneoplastic
syndromes.
