Initial presentation : symptoms and signs

nearly all patients with sclc present with symptomatic disease,
and fewer than 10% of lung cancer patients are diagnosed
prior to clinical presentation of symptoms. one more
effective screening, together with use of chest x-rays, and additional recently,
low-dose spiral computed tomography (ct) scanning,
further as additional sensitive molecular or genomic techniques
could enable for improvement within the ability to diagnose this disease
at an earlier stage, a pair of however sclc can possible be the additional difficult
histologic subtype to seek out early due to its proclivity
for early dissemination. lung cancer additionally tends to affect the
elderly population, and nearly half all patients presenting
with sclc are older than the age of sixty years. 3
a thorough understanding of the symptoms associated
with sclc will facilitate within the appropriate diagnostic workup and,
ultimately, in additional effective management of those symptoms within these
patients. clinical reports have identified the foremost common
symptoms at the time of presentation. four table twenty four. one five delineates
the frequency of those varied signs and symptoms. half-dozen these can
be classified as localized symptoms from the primary tumor,
regional spread of disease, and distant effects from metastatic
disease, further as general symptoms, that could be attributed
to a paraneoplastic result. presenting symptoms will additionally help
predict prognosis during this disease. seven it's been shown that early
presentation of lung cancer is usually related to a specific
pattern of symptoms. eight limited versus in depth disease stage,
the fewer sites of metastatic involvement, sensible performance
standing, and absence of weight loss are all consistently found to
correlate with survival during this disease
