Before the epidemic, we participated in a study on small pulmonary nodules led by Academician Zhong Nanshan, which lasted for three years and will officially end in December this year. We spent two months 300 patients with pulmonary nodules were recruited, and each patient was provided with 5 free CTs and 5 free methylated DNA tests during our follow-up period. The final results will be announced soon. The data currently available are mainly: Proportion of malignant nodules and male to female ratio.
In the past three years, I have personally read each patient’s film, and we have made accurate comparisons for each film. Among them, 16 patients had enlarged nodules during the follow-up period, and no Surgical resection was performed in our hospital, accounting for 5.3%. After the resection, all patients were confirmed to be lung cancer. Most of the patients were lung adenocarcinoma, 1 case of lung squamous cell carcinoma, no small cell lung cancer and large cell lung cancer. It is worth noting that among the surgical patients, the proportion of women is higher, 12 cases are women, and only 4 cases are men. It is already obvious that women account for a higher proportion of cancerous pulmonary nodules. In addition, it should be mentioned separately that in 2 of the 300 patients, the nodules shrunk and disappeared during the follow-up process.
Please explain, this small nodule study has many units across the country, and the total number of people enrolled reaches 10,000. Our 300 patients are only a small part of them and cannot represent the overall patient population. The proportion of cancer can only reflect the current epidemiological situation of pulmonary nodules more accurately after looking at more accurate data after all of them are over.
