Can FDG-PET after neoadjuvant chemotherapy plus nivolumab predict residual disease in non-small cell lung cancer?

Neoadjuvant therapy with nivolumab improves event-free survival (EFS) in patients with resectable non-small cell lung cancer, and a pathological complete response is a predictor of longer EFS. We assessed metabolic responses using 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) before and after neoadjuvant treatment to explore its surrogacy for pathological complete response (pCR). We describe three patients with squamous cell lung carcinoma who underwent neoadjuvant therapy with nivolumab plus chemotherapy, followed by surgery.

Neoadjuvant nivolumab plus chemotherapy followed by resection for superior sulcus tumour with high PD-L1 expression: A case report.

The standard treatment for resectable non-small cell lung cancer (NSCLC) located in the superior sulcus is neoadjuvant chemoradiotherapy followed by highly invasive resection. Based on the results of the CheckMate 816 trial, which showed a marked improvement in the efficacy of neoadjuvant chemo-immunotherapy, we report a case of minimally invasive resection after neoadjuvant nivolumab plus chemotherapy for superior sulcus NSCLC, resulting in a pathologic complete response. The patient was a 76-year-old man with a 65-mm right superior sulcus tumour diagnosed as squamous cell carcinoma with 95% PD-L1.

Efficacy of Continuous Saline Irrigation Therapy for Descending Necrotizing Mediastinitis.

 Descending necrotizing mediastinitis (DNM) is a poor prognosis disease. This study aims to examine the patient background and treatment of DNM and to identify more effective treatments for DNM.  The patient background and treatment of 11 patients who underwent surgery for DNM between November 2010 and June 2021 were studied.

Hypercalcemia in metastatic parathyroid carcinoma followed by hypocalcemia after resection: A case report.

A 72-year-old man was diagnosed with hypercalcaemia 13 years ago. He was diagnosed with hyperparathyroidism associated with a parathyroid tumour and surgery was performed. Postoperatively, his serum calcium levels, which had once normalized, rose again.

Combination treatment by the cervical approach with mediastinal drainage and continuous saline irrigation for descending necrotizing mediastinitis type IIb: a three-case series.

Descending necrotizing mediastinitis (DNM) is a severe, life-threatening disease and requires prompt treatment. The primary treatment for DNM is cervical and mediastinal drainage in addition to antibiotic treatment. However, the most appropriate drainage approach and the effectiveness of additional treatment remain unclear.
