However, a small future liver remnant or central localization of metastases often prevent resectability. In such cases, combining resection with percutaneous ablation may offer a curative-intent treatment option. This study aims to evaluate the oncologic results and morbidity of this combined treatment.</p><p><strong>Materials and methods: </strong>In this retrospective study, 21 patients with advanced colorectal liver metastases underwent a two-stage treatment consisting of planned incomplete resection and percutaneous ablation. Outcomes assessed included overall survival and intrahepatic progression-free survival. Main exclusion criteria were extrahepatic disease and ablation of metastases > 3 cm. Results are reported as medians with 95% confidence intervals and standard deviation.</p><p><strong>Results: </strong>The median number of preoperative intrahepatic metastases was 5 [2-13]. Follow-up was available for 95% of patients, with a median follow-up of 21 months. Intra- und extrahepatic recurrences occurred in 81% (17/21). Median intrahepatic progression-free survival was 5 [0-44] months. Median overall survival was 36.5 [6.6-55] months, resulting in a 1-year survival rate of 91%. Twelve patients (57%) passed away.

His report based on this interview was published in the April issue of two illustrated monthly periodicals in New York City and London. Dam indicated that Röntgen discovered the X-rays on November 8, 1895, and this date has been reproduced consistently in the radiological literature. However, Röntgen himself neither published any detail related to his discovery nor took notice of Dam's assertion. Dam's alleged date has never been certified by any source. When one considers Dam's unsavory background dating from his San Francisco and London sojourns and his misleading of Röntgen - combined with Röntgen's disdain for the press and his lifelong silence on the topic - the well-founded suspicion is raised that the journalist obtained no date from the physicist. Instead, the unscrupulous reporter likely added a date of his own speculation aiming for a deliberate journalistic impact. The innovative in-depth examination of Dam's past and the transcript of Röntgen's interview strongly supports our conclusion. November 8 is incompatible with Röntgen's indirect indications and Zehnder's calendar calculation.</p><p><strong>Conclusion: </strong>The second-hand quality of the date reported and the one-time publication of November 8 as the date of the discovery of X-rays by a journalist with a criminal background and a history of unethical professional behavior, cannot be verifiably confirmed.
