Background:This multi-centre phase II clinical trial is the first prospective evaluation of radioembolisation of patients with colorectal liver metastases (mCRC) who failed previous oxaliplatin- and irinotecan-based systemic chemotherapy regimens.Methods:Eligible patients had adequate hepatic, haemopoietic and renal function, and an absence of major hepatic vascular anomalies and hepato-pulmonary shunting. Gastroduodenal and right gastric arteries were embolised before hepatic arterial administration of yttrium-90 resin microspheres (median activity, 1.7 GBq; range, 0.9–2.2).Results:Of 50 eligible patients, 38 (76%) had received ⩾4 lines of chemotherapy. Most presented with synchronous disease (72%), >4 hepatic metastases (58%), 25–50% replacement of total liver volume (60%) and bilateral spread (70%). Early and intermediate (>48 h) WHO G1–2 adverse events (mostly fever and pain) were observed in 16 and 22% of patients respectively. Two died due to renal failure at 40 days or liver failure at 60 days respectively. By intention-to-treat analysis using Response Evaluation Criteria in Solid Tumours, 1 patient (2%) had a complete response, 11 (22%) partial response, 12 (24%) stable disease, 22 (44%) progressive disease; 4 (8%) were non-evaluable. Median overall survival was 12.6 months (95% CI, 7.0–18.3); 2-year survival was 19.6%.Conclusion:Radioembolisation produced meaningful response and disease stabilisation in patients with advanced, unresectable and chemorefractory mCRC.

Various series have reported similar survival and recurrence rates after resection of colorectal liver metastases (CRLM). If outcomes were predictable, indications for surgery could be improved. This hypothesis was tested in 135 consecutive patients with CRLM who underwent "curative" resection from 1977 to 1997. Among the 132 patients available for follow-up, three groups were identified on the basis of outcome: (1) survival of more than 5 years disease-free (n = 32; 24%); (2) diffuse recurrences within the first 6 months (n = 24; 18%); and (3) discrete recurrences for which reresection was performed (n = 16; 12%). As our results are similar to those reported in the literature, we assumed that about 50% of patients with resectable lesions have recognizable patterns of recurrence. At multivariate analysis, factors significant for disease-free survival (DFS) were the percentage of liver invasion, metastases to lymph nodes at the primary site, number of metastases, preoperative glutamic pyruvic transaminase (GPT) level, and type of liver resection. On the basis of the relative risk (RR) expressed by significant prognostic factors, a score model was developed, and three prognostic groups were defined: Group A, with the best prognostic score, included 23 of 32 (72%) patients who survived more than 5 years, and that with the worst prognostic score (group C) included 22 of 24 (92%) patients with early diffuse recurrences. Extreme (especially unfavorable) outcomes can therefore be predicted. By using improved models of outcome analysis, many patients could be spared surgery as first-line treatment, and stratification criteria could be worked out for future trials.
Peritoneal metastasis from breast cancer is a serious and deadly condition only limited considered in the literature. Our aim was to study prevalence, risk factors, and prognosis of breast cancer peritoneal metastasis. We retrospectively analyzed 3096 women with a diagnosis of invasive breast cancer. We took into consideration presence and localization of breast cancer distant metastasis as well as the possible risk factors and survival from the diagnosis of the breast cancer metastasis. The prevalence of breast cancer peritoneal metastases was 0.7 % (22/3096), representing the 7.6 % (22/289) of women affected by distant metastases. Moreover, independent risk factors for breast cancer peritoneal metastases resulted high grading, lobular invasive histology, and advanced T and N stage at diagnosis. Overall survival after metastasis diagnosis was shorter in women affected by peritoneal metastases or brain metastases in comparison to other metastatic women. Breast cancer peritoneal metastases were uncommon but not rare events with a poor prognosis after standard treatments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
