A 55‐year‐old Chinese man with a right lung mass and lymph node metastasis (T4N3M0 IIIB) was diagnosed with lung adenocarcinoma after a CT‐guided biopsy. With the wide application of next‐generation sequencing (NGS) in tumour detection, we found a rare CCDC85A‐ALK fusion. The patient received alectinib, which had marked efficacy. This is the first report of a lung adenocarcinoma patient harbouring a new uncommon anaplastic lymphocyte kinase fusion that showed a remarkable response to alectinib. NGS aids in selecting treatment in non‐small cell lung cancer patients.

We report a rare case of PDL1-negative advanced gastric adenocarcinoma that improved significantly after camrelizumab plus chemotherapy followed by camrelizumab plus capecitabine as first-line therapy. A 65-year-old woman was diagnosed with a gastric adenocarcinoma in 2017 via contrast-enhanced computed tomography (CT) and endoscopic biopsy. She stabilised after preoperative neoadjuvant chemotherapy, surgery, and postoperative adjuvant chemotherapy. In September 2019, positron emission tomography (PET)/CT re-examination suggested a peritoneal metastasis and multiple lymph node metastases. She then received six cycles of camrelizumab plus chemotherapy. PET/CT indicated that the metastatic foci had disappeared and that she had achieved a clinical complete response(CCR). She was followed-up with camrelizumab plus capecitabine (maintenance therapy). At the time of writing, her progression-free survival is more than 14 months and her quality of life is good. Thus, camrelizumab plus chemotherapy is a useful first-line treatment for HER2- and PD-L1-negative advanced gastric adenocarcinoma.
