ABSTRACT
BACKGROUND:
After patients have a surgical procedure for a gastrointestinal cancer, follow-up is indicated. If cancer progression is documented in patients with mucinous appendiceal adenocarcinoma (MACA), a secondary cytoreductive surgery (SCRS) may be considered.METHODS:
In patients who had a prior complete cytoreductive surgery (CRS), variables associated with the index CRS and SCRS were extracted. These variables were statistically assessed for their impact on survival.RESULTS:
Of 198 MACA patients, 86 (43.4%) had SCRS. The median follow-up was 5.0 years and the median survival was 7 years. Significant prognostic variables associated with the index CRS by univariant analysis was histopathologic grade of MACA-Intermediate (MACA-Int) as compared to other MACA histologic subtypes (p = 0.0164). Significant prognostic variables associated with the SCRS were bowel obstruction (p = 0.0149), interval of CRS to SCRS (p = 0.0059), and completeness of cytoreduction (p = 0.0014).CONCLUSIONS:
In the analysis of variables from SCRS, the interval from CRS to SCRS ≤24 months indicates an aggressive biology of the disease. The CC score of complete versus incomplete decreased median survival from 11 to 4 years. A composite of these two variables allowed prediction of survival of 50% when patients showed these two favorable variables and only 9.1% when these variables were unfavorable.Palavras-chave
