Shortness of breath and chest pain

Liver biopsy will reveal the cause of the liver dysfunction and confirm whether this patient has small cell lung cancer (SCLC), as suspected, and whether it has spread to the liver. This will affect chemotherapy options.

Most cases of SCLC will present in advanced stages, be inoperable, and have a dismal prognosis. Only about 5% of patients present at an early stage (Ia, Ib, or IIa). The National Comprehensive Cancer Network (NCCN) guidelines recommend that patients with advanced disease be managed with aggressive chemoradiation therapy and immunotherapy. 

SCLC is the most aggressive lung cancer subtype. It is almost always associated with smoking. It accounts for 10%-15% of all lung cancers. Rapid tumor growth may lead to obstruction of major airways, with distal collapse leading to postobstructive pneumonitis, infection, and fever. About 70% of patients show metastatic spread at presentation, and the liver is one of the most common sites of metastasis.

Unlike non-SCLC, for which the prognosis has improved in part because of several new drug approvals from the US Food and Drug Administration, the prognosis for SCLC has not changed substantially in the past two decades and remains poor. However, with immunotherapy, the outlook may be improving. The NCCN recommends atezolizumab in combination with carboplatin and etoposide for first-line treatment of adult patients with extensive-stage SCLC. Furthermore, the approval of durvalumab in combination with chemotherapy and the approval of lurbinectedin, a novel chemotherapy agent approved for second-line treatment of SCLC, have added to the therapeutic options for patients with advanced SCLC.
