Neoplasia risk in patients with Lynch syndrome treated with immune checkpoint blockade

Abstract

Metastatic and localized mismatch repair-deficient (dMMR) tumors are exquisitely sensitive to immune checkpoint blockade (ICB). The ability of ICB to prevent dMMR malignant or pre-malignant neoplasia development in patients with Lynch syndrome (LS) is unknown. Of 172 cancer-affected patients with LS who had received ≥1 ICB cycles, 21 (12%) developed subsequent malignancies after ICB exposure, 91% (29/32) of which were dMMR, with median time to development of 21 months (interquartile range, 6–38). Twenty-four of 61 (39%) ICB-treated patients who subsequently underwent surveillance colonoscopy had premalignant polyps. Within matched pre-ICB and post-ICB follow-up periods, the overall rate of tumor development was unchanged; however, on subgroup analysis, a decreased incidence of post-ICB visceral tumors was observed. These data suggest that ICB treatment of LS-associated tumors does not eliminate risk of new neoplasia development, and LS-specific surveillance strategies should continue. These data have implications for immunopreventative strategies and provide insight into the immunobiology of dMMR tumors.

Extended Data Fig. 3 Paired analysis of pre- and post-immune checkpoint blockade (ICB) exposed tumors using MSK-IMPACT next-generation sequencing derived data22.

Nonsynonymous somatic mutations from the MSK IMPACT variant call format (VCF) output from each sequenced patient tumor were input into the SnpEff program v5.1d (https://pcingola.github.io/SnpEff/) to predict translated amino acid sequences for each respective mutation. The number of unique mutation associated neoantigens (MANA) was determined by taking the defined peptide sequence and evaluating all potential contiguous 9′mer variations using a sliding reading frame. a, Comparison of total missense mutations in pre- and post-ICB tumors. b, Comparison of mutation associated neoantigens between pre- and post-ICB tumors. All boxplots are composed of median (central line), 25th–75th percentile (box edges), and minimum and maximum values (whiskers). All analyses included 9 distinct pre and 9 distinct post tumors paired for 9 unique patients. p-values are derived from pairwise t-testing based on patient.

Mean and standard deviation (SEM) are represented and compared using ordinary one way ANOVA test corrected for multiple comparisons.*: P ≤ 0.05 and P > 0.01, ns: non significant.

Extended Data Fig. 6 Incidence of subsequent primary malignancies (SPM) in the immune checkpoint blockade (ICB) treated and non-ICB (chemotherapy) treated patients with Lynch syndrome.

a, SPM incidence at 5-years matched follow-up in the ICB treated (pre- and post-ICB) and non-ICB treated cohort (pre- and post-chemotherapy). The number of matched patient pre/post ICB or pre/post chemotherapy is reported below the figure. The 5 year incidence of 2nd neoplasm for each clinical condition is reported above the box plot representing the mean and standard deviation (SEM). Pre and post 5 year incidence were compared using paired t test. ns: non significant, P > 0.05. b, SPM incidence in patients defined as high risk (HR). HR-patients were defined as patients presenting with multiple non concomitant cancers (> = 2) in a pre-ICB delay matched with post-ICB follow up. 3-year and 5-year incidence calculation was performed excluding the index cancer and concomitant cancers ( < 1 month between diagnoses of cancers). The number of matched patient pre/post ICB or pre/post chemotherapy for 3-year and 5-year incidence of 2nd neoplasm is reported below the figure. The 3-year and 5-year incidence of 2nd neoplasm for each clinical condition is reported above the box plot representing the mean and standard deviation (SEM). Pre and post 3-year or 5-year incidence were compared using paired t test. ns: non significant, P > 0.05. c, Swimmers plot demonstration cancer occurrence pre- and post-ICB exposure in the HR patient cohort over time in months for patients with match pre and post ICB follow up. The patient numbers for the ones developing post ICB neoplasms correspond to those reported in Fig. 1 (patients 15, 8, 7 and 4). Other high-risk patients (HR) are numerated from 1 to 12. Median ICB duration and follow up (FU) are reported for patients developing post ICB neoplasms and for the patients not developing post ICB neoplasm. The order of neoplasm occurring during the matched pre and post ICB follow up is reported. No statistical comparison was performed. d, Cumulative post-ICB cancer incidence in the ICB-exposed HR-patient cohort. High risk Patients with a matched follow up pre- and post-ICB of 36 months were selected and all non-index cancers occurring during the window of observation were accounted for. Cumulative incidence is reported as the cumulative sum of non-index cancers occurring during the period of observation. Number of patients and cumulative observation time in months are reported. Fisher’s exact test comparing the cumulative observation time without a neoplasm event to the number of months with an event was used for statistical analysis. ***: P < 0.001.
