A case report of pulmonary combined small cell carcinoma with enteric adenocarcinoma.

ABSTRACT:

Background

Combined small cell lung cancer (CSCLC) is rarely reported, which accounting for only 2% to 5% of all lung cancers. And enteric adenocarcinoma is also a rare subtype of non-small cell lung cancer (NSCLC) whose histomorphology is very similar to lung metastatic colorectal cancer.

Case description

We report a case with both small cell lung cancer (SCLC) and enteric adenocarcinoma for the first time. The patient was admitted to our hospital due to the left lung mass after a routine examination. She underwent computed tomography scan and needle biopsy, which showed the tumor consisted of two different components (70% SCLC and 30% enteric adenocarcinoma). The mixed density nodules were also observed in the right lung's lower lobe, and positron emission tomography-computed tomography (PET-CT) showed an increase of standard uptake value (SUV) greater than 2.5 in the right lung. Imaging and pathology experts agreed that the nodules of right lung were metastatic lesions after multi-disciplinary treatment (MDT). Considering the epidermal growth factor receptor (EGFR) p.L861Q mutation, the patient received gefitinib and EP chemotherapy, and she responded well to the combination therapy. At last follow-up, the progression-free survival (PFS) reached 11 months, and the adverse effects were clinically acceptable and tolerable.

Conclusions

This case report provides direct evidence for EGFR-tyrosine kinase inhibitor (TKI) and EP chemotherapy is effective and useful in the treatment of CSCLC patients with enteric adenocarcinoma.

Project description:Pulmonary sarcomatoid carcinoma (PSC) is a rare subtype of lung malignant tumor. Conventional chemotherapy has a suboptimal effectiveness. PSC has the characteristics of rapid disease progression and poor prognosis. We herein report a 56-year-old male patient with substantial smoking history was pathologically diagnosed as PSC, cT4N0M0 IIIA stage. Peripheral blood NGS showed TP53 mutation. The patient had poor tolerance to the first-line chemotherapy regimen "albumin paclitaxel + cisplatin," but the severe anemia was significantly improved after 5 days of anti-angiogenic therapy with Anlotinib. At this time, the patient received anti-PD-1 immunotherapy with Tislelizumab. Half a month later, degree III liver injury occurred repeatedly. After excluding drug-induced liver injury, we found that HCV-RNA 3.10 × 105 IU/ml and suspended all anti-tumor therapy. After the start of anti-HCV treatment with Epclusa, the treatment of Tislelizumab combined with Anlotinib was restarted, and there was no liver injury after that. The patient received monthly maintenance therapy with Tislelizumab combined with Anlotinib to the present. The pulmonary lesions continued to decrease, and only one lung cavity is left. The patient has achieved clinical complete remission (CCR) with PSF over 20 months. Our findings suggest that Tislelizumab combined with Anlotinib may be a preferred strategy in PSC complicating TP53 mutation. Core tip: Immune-check point inhibitors (ICIs) have been reported for the treatment of PSC in a small number of case reports and retrospective analysis, but there are few reports of ICIs combined with anti-angiogenic drugs. This patient was diagnosed as locally advanced PSC complicated with TP53 mutation and hepatitis C. After 14 cycles of Tislelizumab combined with Anlotinib treatment (during the course of treatment, several courses were not treated on time for economic reasons, rather than adverse reactions), the patient has achieved CCR. III degree liver injury occurred during the treatment, and the liver function returned to normal range after anti-hepatitis C treatment, which did not affect the continued treatment of this regimen.
