No full textPreserving fossilized soft tissues: advancing proteomics and unveiling the evolutionary history of cancer in dinosaurs
No full textUnderstanding how life-history strategies influence cancer susceptibility in dinosaurs requires molecular-level analysis of preserved soft tissues. While previous research has largely focused on skeletal remains, the discovery of soft tissue structures in fossils, such as Telmatosaurus transsylvanicus, highlights the need for a new approach. Paleoproteomics offers a transformative opportunity to analyze ancient proteins, re-vealing evolutionary trade-offs between growth, reproduction, and cancer suppression. This study argues that prioritizing fossil collection and soft tissue preservation is crucial, as future advances in molecular techniques will allow deeper insights into disease evolution. By integrating life-history theory with paleopathology, we can better understand the selective pressures that shaped cancer susceptibility in extinct species and identify po-tential mechanisms of tumor resistance. This commentary highlights the necessity of long-term fossil conservation efforts to support future breakthroughs in evolutionary biology and comparative oncology
Overall Survival of Elderly Patients Having Surgery for Colorectal Cancer Is Comparable to Younger Patients: Results from a South Asian Population
No full textIntroduction. There has been a continuous debate on whether elderly patients with colorectal cancer (CRC) fair worse. The aim of this study is to assess the thirty-day mortality (TDM) and overall survival (OS) of elderly patients undergoing surgery for CRC. Method. OS between two groups (≥70 versus <70 years) having surgery for CRC was analyzed. Demographics, tumour characteristics, and serological markers were considered as independent factors. Multivariable analysis was done using the Cox proportional hazard model. We also compared overall survival in the elderly versus those <60 and <50 years. Results. 477 patients, 160 elderly (55% male; median age 75, range 70–89) and 317 younger patients (49% male; median age 55, range 16 to 69), were studied. Overall survival in CRC patients ≥70 is comparable to <70 (P=0.45) and <60 years (P=0.08). Poor OS was observed in the ≥70 versus <50 years (P=0.03). TDM in the elderly was poor (P<0.05). Postoperative cardiac complication was the only determinant affecting survival in the elderly (P=0.01). Conclusion. OS in elderly CRC patients having surgery is not worse compared to <70 and <60 years although the TDM was higher. Postoperative cardiac complications significantly affected OS in those ≥70 compared to those <50 years. Chronological age alone should not negatively influence surgical decision-making in the elderly
