AdC, adenocarcinoma; BMI, body mass index; CI, confidence interval; ECOG PS, Eastern Cooperative Oncology Group performance status; HR, hazard ratio; MMR, mismatch repair; NMTB, National Molecular Tumor Board; ref, reference; SCC, squamous-cell carcinoma; TMB-H, tumor mutational burden high (>10 mutations per megabase).
‘Other histologies’ include neuroendocrine carcinoma, basal cell carcinoma, mesothelioma, carcinosarcoma, atypical meningioma, and transitional cell carcinoma.
‘Other primary sites’ include female genital tract excluding ovaries, esophagus-stomach, head-and-neck, skin, pancreas, and urinary tract.
Time from first diagnosis of cancer to date of NMTB.
The 31 patients with locally advanced disease are scored 0.
Patients may have more than one metastatic site. Rarer metastatic sites are not shown or tested.
Seven cases excluded: Data not available (four cases), high numbers of variants of low frequencies due to formalin fixation, prior treatment with temozolomide, and biallelic germline MMR gene mutation.
