- Quantifying the genetic correlation between cancers can provide important insights into the mechanisms driving cancer etiology. Using genome-wide association study summary statistics across six cancer types based on a total of 296,215 cases and 301,319 controls of European ancestry, here we estimate the pair-wise genetic correlations between breast, colorectal, head/neck, lung, ovary and prostate cancer, and between cancers and 38 other diseases. We observed statistically significant genetic correlations between lung and head/neck cancer (r(g) = 0.57, p = 4.6 x 10(-8)), breast and ovarian cancer (r(g) = 0.24, p = 7 x 10(-5)), breast and lung cancer (r(g) = 0.18, p = 1.5 x 10(-6)) and breast and colorectal cancer (r(g) = 0.15, p = 1.1 x 10(-4)). We also found that multiple cancers are genetically correlated with non-cancer traits including smoking, psychiatric diseases and metabolic characteristics. Functional enrichment analysis revealed a significant excess contribution of conserved and regulatory regions to cancer heritability. Our comprehensive analysis of cross-cancer heritability suggests that solid tumors arising across tissues share in part a common germline genetic basis.

- Background: This study aimed to assess the impact of cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) on the survival outcomes for patients with gastric cancer and peritoneal carcinomatosis (PC).Methods: A retrospective analysis of the National Cancer Database from 2004 to 2020 identified patients with topography and histology codes consistent with gastric adenocarcinoma who underwent CRS/HIPEC. The exclusion criteria ruled out known other distant metastasis and missing key data. The study compared the CRS/HIPEC group with patients who had stage IV disease (with the same exclusions for distant metastases) and received systemic chemotherapy but no surgery to the primary site.Results: The study included 148 patients who underwent CRS/HIPEC. Their median age was 57 years (interquartile range [IQR], 47–66 years), with 57.4% of the patients identifying as male and 73.6% identifying as white. Most of the CRS/HIPEC patients had locally advanced disease, with 33.8% having pT4 disease and 23% patients having pN3 status. The Charlson–Deyo scores were 0 for 77% and 1 for 16.9% of the patients. The overall survival (OS) among the stage IV patients managed with CRS/HIPEC was significantly longer than for the patients receiving only systemic chemotherapy (median survival, 18.1 vs 9.3 months; p < 0.001), and the 1-year OS was 72.6% versus 38.8% (p < 0.05)). Among the stage IV patients, CRS/HIPEC showed better survival than systemic chemotherapy (hazard ratio [HR], 0.57; 95% confidence interval [CI], 0.44–0.73; p <.001) when control was used for the Charlson Deyo score, histology, age, and sex.Conclusions: These results suggest the association of CRS/HIPEC with improved survival for selected patients with gastric adenocarcinoma and peritoneal disease. Some of this difference may have been due to selection bias, but the differences in the survival curves are robust.
