Purpose Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal malignancy that occurs primarily in children and adolescents. The clinical and pathological features of IMT in adult patients are not well understood.
Materials and Methods We retrospectively searched for records of adult patients with IMT at Fudan University Shanghai Cancer Center from 2006 to 2021. Clinicopathological data, treatments, and outcomes were collected and analyzed.
Results Thirty adult patients with IMT, mostly women (60.0%), were included. The median age of the patients was 38 (21-77). The most common primary site was abdominopelvic region (53.3%), followed by lungs (20.0%). Seven patients had an abdominal epithelioid inflammatory myofibroblast sarcoma (EIMS). The positivity rate of anaplastic lymphoma kinase (ALK) was 81.5% (22/27). Sixteen patients with advanced ALK-positive disease received crizotinib, with an objective response rate (ORR) of 81.3% and a disease control rate of 87.5%. The median progression-free survival was 20.8 months. EIMS was associated with more aggressive behavior; however, the prognosis was similar to that of non-EIMS patients after treatment with an ALK inhibitor. At a median follow-up time of 30 months (95% confidence interval [CI], 13.6 to 46.4), the 5-year overall survival was 77% (95% CI, 66 to 88) in all patients.
Conclusion Adult IMTs appeared more aggressive, with a higher incidence of recurrence and metastases, and patients with EIMS had more aggressive cases. Treatment with ALK inhibitors resulted in a high ORR and a durable response, which suggested that ALK inhibitors could be used as a first-line treatment option in adult patients with ALK-positive advanced IMT.

Purpose
Nonylphenol (NP) is an endocrine disruptor found in products such as cleaners, plastics, and detergents. It exerts actions similar to endogenous 17β-estradiol (E2) and is reported to influence various cancers. However, its role in colon cancer remains elusive.
Materials and Methods
Colon cancer cell lines COLO 205 and SW480 were employed in our study. The cells were treated with NP or E2 followed by measurement of apoptosis and proliferation using flow cytometry and MTT assays, respectively. G protein–coupled estrogen receptor 30 (GPR30) expression was visualized using immunofluorescence and Western blot. To investigate the underlying mechanism, the expression levels of GPR30, p-protein kinase A (PKA), c-myc, cyclin D1, and ERK1/2 were analyzed using Western blot. Meanwhile, the GPR30 antagonist G15 was utilized to validate the role of GPR30 in colon cancer progression. Finally, the effect of a GPR30 inhibitor on tumor growth was determined in vivo using tumor xenograft mouse models.
Results
NP facilitated the proliferation of colon cancer cells and induced apoptosis failure in vitro. Western blot revealed increased GPR30 expression levels in response to NP treatment. Cyclin D1, p-PKA, c-myc, and proliferating cell nuclear antigen, proteins that regulate the cell cycle, were all upregulated by NP, and NP-mediated ERK1/2 activation and subsequent cell proliferation were abrogated by the GPR30 inhibitor G15. Moreover, colon cancer mice that received G15 administration demonstrated impaired tumor growth in vivo.
Conclusion
Low dose NP promotes the growth of colon tumors through GPR30-mediated activation of ERK1/2 signaling.
