1/19/2020 · In a study looking at initial CT scans (and the CT component of PET/CT), the mean diameter doubling time for small cell lung cancer was 70 days for the primary tumor, and 51.1 days for involved lymph nodes.
Dr Daniel J Bell and Dr Balint Botz et al. The volume doubling time ( VDT) is an important volumetric parameter primarily used in lung cancer screening and follow-up by chest CT. Volume doubling time is defined as the time required for a growing nodule to double its volume. A longer VDT suggests a more benign course, whilst a short VDT is …
The aim of this study was to evaluate the volume doubling time (VDT) of lung cancer detected in our annual chest radiograph screening program and to compare it with those previously reported for computed tomography (CT) screening. In total, 209 patients who had a measurable tumor shadow and a histor.
Prognostic value of doubling time in lung cancer . Mattson K, Holsti LR. The volume doubling time (DT) of 27 measurable primary pulmonary carcinomas was calculated. The prognostic value of the DT was analysed in relation to survival, age, initial size of the tumour, histology, duration of symptoms, and treatment.
Particularly, a tumor doubling time?> ?180 days is associated with superior survival in patients with metachronous lung cancer.

3/1/2008 · For a slower-growing cancer, with a doubling time of 500 days, the radiograph “window” will be 2500 days (6.8 years), the CT one 4000 days (almost 11 years) and the “survival time” from 10 mm to death 5000 days (13.7 years). For the extremely slow-growing ones, with a doubling time of 1500 days, multiply these figures with three.
