The in vitro development of human mast cells from fetal liver cells with recombinant human stem cell factor in serum-containing RPMI was compared to that in AIM-V media with and without serum. Compared to serum-containing media, AIM-V media caused mast cells to develop earlier and in greater numbers. By 2 weeks, about 60% of cells in serum-free AIM-V medium were phenotypic mast cells, ~2 times the percentages in serum-containing media. By 6 weeks the percentages of mast cells were ≥80% under all conditions, but the number of mast cells was 3-4-fold greater in serum-free AIM-V medium than in serum-supplemented media. Mast cells obtained in serum-free AIM-V medium exhibited rounded nuclei, like tissue-derived mast cells; mast cells obtained in serum-supplemented media had segmented nuclei. By 10-12 weeks of culture about 40% of the AIM-V-derived cells showed strong chymase immunocytochemical staining, a pattern observed for only 14% of the cells in serum-containing media. AIM-V medium is a suitable medium for the development of human mast cells in vitro, and permits an earlier, more selective and greater expansion of mast cells than serum-containing media.

Objective: This study aimed to evaluate the presence of pathological residual tumor (pRT) in each initial disseminated site after neoadjuvant chemotherapy (NACT) to assess the appropriate surgical margins during interval debulking surgery (IDS) for a favorable prognosis. Methods: This prospective descriptive study included patients with stage IIIC–IV epithelial ovarian, fallopian tubal, and peritoneal cancer. One hundred eleven patients underwent diagnostic exploratory laparotomy, and their initial intra-abdominal dissemination statuses were recorded. Any tumor >1 cm in diameter found during the exploratory laparotomy was resected during IDS even if it was macroscopically invisible after NACT. The pRT rate after NACT and negative predictive value (NPV; probability that sites with macroscopically invisible tumors have no pRT) during IDS were assessed in each disseminated site. Results: A median of 5 NACT cycles were performed. Sites with a high incidence of pRT and low NPV included the rectosigmoid colon (71.4%, 38.6%), transverse mesentery (70.3%, 50.0%), greater omentum (68.3%, 51.7%), right diaphragm (61.9%, 48.1%), paracolic gutters (61.1%, 50.0%), and vesicouterine pouch (56.6%, 50.0%). Organs/tissues with a high incidence of pRT featured a low NPV. The median progression-free survival and overall survival in this cohort were 27.7 and 71.9 months, respectively. Conclusion: Even if a disseminated site >1 cm in diameter before NACT is invisible during IDS, microscopic disease remains present within it. The appropriate surgical margins for IDS with a favorable prognosis could be secured by resecting a lesion of >1 cm before NACT even if it is invisible during IDS.
