S1 Ep127: Exploring the Value of Preoperative CAPTEM in Atypical Lung NETs

Oncology On The Go

In a conversation with CancerNetwork®, Georgios Evangelou, MD, MSc spoke about his manuscript titled Neoadjuvant Capecitabine Plus Temozolomide in Atypical Lung NETs, which he and his coauthors published in the July issue of ONCOLOGY®.
Evangelou, a medical oncologist and consultant in the 3rd Department of Medicine at Sotiria General Hospital in Athens, Greece, reviewed the results of a case study involving the use of neoadjuvant capecitabine (Xeloda) plus temozolomide (Temodar; CAPTEM) for a 62-year-old woman with well-differentiated atypical carcinoid. The patient was asymptomatic at diagnosis, with imaging revealing an atypical bronchial neuroendocrine tumor (NET) as well as a pancreatic mass indicating another NET.
This patient subsequently underwent treatment with CAPTEM, which resulted in minor volume reductions of masses in the left lower lobe and subcarinal lymph node after 6 months of therapy. Although the pancreatic mass increased in size, Evangelou and colleagues excised it via central pancreatectomy, allowing the patient to resume treatment with CAPTEM for 6 additional months and undergo lobectomy with lymph node dissection. Further use of CAPTEM produced a partial response in the mediastinal lymph nodes and a 21% reduction in the size of the primary tumor.
Following treatment, the patient was able to recover without any significant complications. Additionally, follow-up scans revealed no avid lesions, and there were no signs of disease recurrence at 24 months after the lobectomy. Based on the results of this case study, the authors noted how neoadjuvant therapy may significantly impact the management of patients with atypical carcinoids, although larger clinical trials may be necessary to affirm the potential survival benefit of CAPTEM.
“I hope that others will recognize the potential value of CAPTEM as a neoadjuvant treatment in similar cases. Sometimes, these cases are very difficult to manage; you need the neoadjuvant treatment because it can offer tumor shrinkage. Eventually, it can lead to radical excision of the disease,” Evangelou said. “We need larger studies to better understand the effectiveness of the regimen as a neoadjuvant treatment.”
