ObjectiveThe aim of this study was to evaluate the characteristics of gastric-type adenocarcinoma (GAS) of the uterine cervix, compared with usual-type endocervical adenocarcinoma (UEA) and squamous cell carcinoma (SCC), using magnetic resonance (MR) imaging.Materials and MethodsA total of 15 histopathologically defined GASs, 12 UEAs, and 40 SCCs were retrieved from archive files and were included for evaluation. Microscopic features, as well as topography and tumor growth pattern, and presence or absence of coexistence of cystic cavities were evaluated. Accuracy of evaluation for parametrial tissue and vaginal wall invasion was also evaluated by 2 diagnostic radiologists, independently, without clinical information on cases.ResultsThirteen (86.70%) of the 15 cases of GAS exhibited tumors in the higher portion of cervical canal or the entire cervix. On the other hand, SCCs and UEAs were mainly located in the lower portion of cervical canal, at a frequency of 21 of 40 (52.5%) and 9 of 12 (75.0%), respectively. Involvement of the corpus was observed more frequently in cases of GAS with an occurrence of 8 of 15 (53.3%), whereas in all cases of UEA and in 5 of the 40 cases of SCC, the corpus was free of tumor. In GAS cases, the predominant pattern of growth was highly infiltrating and endophytic (14/15, 93.3%), whereas an exophytic growth pattern was observed in 31 (77.5%) of the 40 SCC cases and 11 (91.7%) of the 12 UEA cases. Cystic cavities associated with tumors were identified in only 1 case of SCC but occurred in 12 (80.0%) of the 15 GASs and 4 (33.3%) of the 12 UEAs. Diagnostic accuracies of more than 70% and more than 60% were reached in parametrial invasion and vaginal invasion, respectively, in GAS.ConclusionDistinctive MR imaging features of GAS were infiltrating mass of endophytic growth, location in the upper cervical canal, and association with tiny cysts. This characteristic appearance can be a clue for the evaluation of extent of tumor based on MR imaging.

ObjectiveGastric-type mucinous carcinoma (GAS) is a novel variant of mucinous carcinoma of the uterine cervix, characterized by aggressive clinical behavior and absence of high-risk human papillomavirus. We conducted this study to evaluate the chemosensitivity of GAS compared with that of usual-type endocervical adenocarcinoma (UEA) in patients who had been enrolled in our previous study.MethodsOf 52 patients from our previous phase 2 study (SGSG005) of neoadjuvant chemotherapy with docetaxel and carboplatin for stage IB2 to IIB nonsquamous cervical cancer, 47 (stage IB2, 12; stage IIA2, 7; stage IIB, 28) were enrolled in this study with written informed consent. The biopsy specimens before neoadjuvant chemotherapy and surgical specimens after chemotherapy were centrally reviewed based on the updated World Health Organization classification (2014).ResultsOf 47 patients with nonsquamous cell carcinoma, 20 (42.6%) were diagnosed with UEA, 13 (27.7%) with GAS, 12 (25.5%) with adenosquamous carcinoma, and 1 patient each (2%) with small cell carcinoma and serous carcinoma. Consequently, 33 patients, consisting of 20 patients with UEA and 13 patients with GAS, were eligible for the current study. The response rate of GAS was significantly lower than that of UEA (46.2% vs 85.0%, P = 0.048). Of 16 cases of stage II UEA, 11 (68.8%) were downstaged on microscopic examination of postsurgical specimens, but none of the 8 patients with stage II GAS showed any response (P < 0.01). Two inoperative tumors were GAS. With a median follow-up duration of 56 months, the 5-year progression-free and overall survival rates of GAS were significantly worse than those of UEA (38.5% vs 75.0% [P = 0.011] and 36.9% vs 90.0% [P < 0.001], respectively).ConclusionsThese findings suggest that GAS should be distinguished from UEA by its chemoresistance, necessitating an alternative treatment strategy established for this distinct subtype of endocervical adenocarcinoma.
