Abbreviations: F, female; M, male; TNM, tumor-nodes-metastases (according to 8th edition of lung cancer classification); rTNM, recurrence or retreatment tumor-nodes-metastases (according to 8th edition of lung cancer classification); RUL, right upper lobe; RLL, right lower lobe; LUL, left upper lobe; ML, middle lobe; LLL, left lower lobe; *, resected; -, post radiochemo and/or immunotherapy; Tx, no remaining primary tumor visible at location of original tumor
Characteristics of patients (n = 28) including sex, patient age at time of diagnosis, histopathological tumor type, location and size of the primary tumor as well as TNM staging (8th edition) according to the multidisciplinary conference. In 7 cases, the patients had previously undergone treatment, either surgical resection (n = 4) or systemic therapy (n = 3), but developed recurrence in a different location than the original tumor. In those patients except one, no primary tumor could be measured in the TNM restaging (n = 6). In one patient (patient 25), the recurrence occurred in the location of the original tumor
