OBJECTIVETo study the clinicopathologic features, immunophenotype and prognosis of matrix-producing metaplastic carcinoma (MPC).
METHODSSixteen cases of MPC diagnosed between 2002 and 2012 in West China Hospital were identified. The clinicopathologic features were analyzed. Immunohistochemistry for E-cadherin, S-100 protein, CK5/6, HCK, PCK, CK7, CK8, p63, SMA, EMA, CD99, MSA, CK14, EGFR, ER, PR, HER2 and Ki-67 was performed with EnVision method. The clinical outcome was evaluated and compared to matched controls of invasive ductal carcinoma.
RESULTSAll patients were women and ranged in age from 29 to 69 years (median age 48 years). The median size of primary tumor was 4 cm. Most of the tumors were well-circumscribed with expansile and multinodular appearance. Histology showed invasive carcinoma with a direct transition from carcinoma to cartilaginous/chondromyxoid matrix without an intervening spindle cell component. Tumor distribution was either nodular or diffuse. The matrix component accounted for 10%-80% of the tumor volume. All the tumors were strongly positive for S-100 protein and basal-like cytokeratin with triple negative phenotype (ER, PR and HER2 negative). Alcian blue stain was positive for the cartilaginous/chondromyxoid matrix. Compared with invasive ductal carcinoma, patients with MPC had increased locoregional recurrence (P = 0.010), increased distant recurrence (P = 0.011) and shorter disease-free survival (P = 0.017).
CONCLUSIONSMPC is a rare variant of mammary metaplastic carcinoma with unique characteristics of morphology and immunohistochemical staining pattern. This subtype seems to have aggressive biologic behavior.

Objective:To investigate the clinical efficacy of infra-acetabular screwing in the treatment of acetabular fractures.Methods:A retrospective analysis was conducted of the 22 patients with acetabular fracture who had been admitted to Department of Trauma and Orthopedics, The Affiliated Hospital of Traditional Chinese Medicine, Xinjiang Medical University from January 2016 to January 2019. They were 16 males and 6 females, aged from 19 to 65 years (mean, 45.2 years). According to Letournel-Judet classification, there were 2 anterior column fractures, 12 anterior plus posterior hemi-transverse fractures, 3 T-shaped fractures and 5 both-column fractures. All patients were treated with infra-acetabular screwing through the ilioinguinal approach. Recorded were the patients' operation time, intraoperative blood loss, reduction quality, fracture union time, hip function and complications.Results:Operation time for this cohort ranged from 115 to 285 min (mean, 160 min), and intraoperative blood loss from 360 to 1,600 mL (mean, 650 mL). By the Matta scoring, fracture reduction was assessed as excellent in 14 cases, as good in 5 cases and as poor in 3 cases, giving an excellent and good rate of 86.4% (19/22). Of this cohort, 21 were followed up from 12 to 45 months (mean, 28.5 months) and one was lost to the follow-up. The fracture healing time for 21 patients ranged from 1.6 to 3.0 months, averaging 2.2 months. No patient had fracture displacement. The Merle d’Aubigné & Postel hip scores at the last follow-up ranged from 8 to18 points (average, 16 points), giving 12 excellent, 6 good, 2 fair, and one poor cases and an excellent and good rate of 85.7% (18/21). Follow-ups observed injury to the lateral femoral cutaneous nerve in one case, deep venous thrombosis of lower limb in 2 cases, superficial wound infection in one case and traumatic arthritis in one case, yielding a total rate of compilations of 23.8% (5/21).Conclusion:Application of infra-acetabular screwing after anatomical reduction of an acetabular fracture can effectively enhance the strength of internal fixation with no risk of fracture re-displacement, conducive to early functional exercise of the patient and leading to good clinical efficacy.

The aim of acetabular fracture surgery is to achieve anatomical reduction and potent fixation, to allow early functional rehabilitation of the injured hip joint, and to avoid postoperative complications such as joint stiffness, muscle atrophy, thrombosis, pneumonia and traumatic arthritis. In the past 10 years, the concept of minimally invasive treatment has developed rapidly. As a minimally invasive and precise internal fixation method, the pelvic channel screw concept has been widely used including infra-acetabular channel screw which is a channel on the inside of the hip joint, pass through both columns and parallel to the pelvic quadrilateral. Infra-acetabular channel screw is a combination of quadrilateral wall screw technique and pelvic osseous fixation pathways screw technique, which is applied to acetabular fractures that anterior and posterior column Separated. In Recent years, anatomical studies have found that more than 90% population exist a channel to place an 5 mm infra-acetabular screw safely, and described its entry point, angle, channel morphology, furthermore, vitro biomechanical have confirmed that the infra-acetabular channel screw can increase the fixation strength of acetabular fractures significantly. The clinical application has tested and verified its operability. The patients good recovery also proved the application value of the infra-acetabular screw. Thus a retrograde infra-acetabular screw technique is derived.

Journal of Gynecologic Oncology 2021;32(2):e17-
Objective:
To compare 5-year disease-free survival (DFS) and overall survival (OS) rates of laparoscopic radical hysterectomy (LRH) and abdominal radical hysterectomy (ARH) for stage IB1 and tumor size <2 cm with visible or invisible tumors.
Methods:
We retrospectively compared the oncological outcomes of 1,484 cervical cancer patients with IB1 and tumor size <2 cm on final pathology, who received ARH (n=899) or LRH (n=585) between January 2004 and December 2016. Patients were divided into visible tumor subgroup (ARH: n=668, LRH: n=444) and invisible tumor subgroup (ARH: n=231, LRH:n=141) according to tumor type.
Results:
LRH and ARH showed similar 5-year DFS and OS rates (93.3% vs. 93.1%, p=0.997;96.2% vs. 97.5%, p=0.351) in total study population. LRH was not associated with worse 5-year DFS rate (hazard ratio [HR]=0.96; 95% confidence interval [CI]=0.58–1.58; p=0.871) or OS rate (HR=1.37; 95% CI=0.65–2.89; p=0.409) by multivariable analysis. In the visible tumor subgroups, LRH and ARH showed similar 5-year DFS and OS rates (91.9% vs. 91.9%, p=0.933; 95.0% vs. 96.9%, p=0.276), and LRH was not associated with worse 5-year DFS or OS rate (p=0.804, p=0.324). In the invisible tumor subgroups, LRH and ARH also showed similar 5-year DFS and OS rates (97.3% vs. 97.1%, p=0.815; 100% vs. 99.5%, p=0.449), and LRH was not associated with worse 5-year DFS rate (p=0.723).
Conclusions
Among patients with stage IB1 and tumor size <2 cm, whether the tumor is visible or not, the oncological outcomes of LRH and ARH among cervical cancer patients are comparable. This suggests that LRH may be suitable for stage IB1 and tumor size <2 cm with visible or invisible tumors.
