ObjectiveTo explore the imaging characteristics of lung cancers associated with cystic airspaces (LCCA) and the effects of different treatment regimens. MethodsA retrospective analysis was conducted on the clinical and radiological data of LCCA patients who underwent surgical resection and pathological confirmation at the Department of Thoracic Surgery, the First Affiliated Hospital of Soochow University from 2016 to 2023. The relationship between various radiological classifications and clinical pathology was studied. Based on the postoperative adjuvant treatment follow-up results, the effects of different treatment regimens were analyzed. ResultsA total of 147 patients were included, including 90 males and 57 females, with a median age of 63 (55, 70) years. There were 21 patients of imaging typeⅠ, 50 patients of typeⅡ, 57 patients of type Ⅲ, and 19 patients of type Ⅳ. The lobulation sign or burr sign of typeⅠcyst walls (P=0.004), and intracystic septa (P=0.030) were more commonly seen in the high-aggressiveness group. The components of the cyst walls or nodules of types Ⅰ-Ⅳ in the high-aggressiveness group were mostly solid or sub-solid (P<0.05). Multivariate logistic regression analysis indicated that subsolid cyst wall (OR=4.734, P=0.023), solid cyst wall (OR=97.972, P<0.001), and the lobulation sign or burr sign of the cyst wall (OR=13.215, P=0.024) were independent risk factors for aggressiveness. Fifty-eight patients received adjuvant therapy after surgery, including 22 in the chemotherapy group, 15 in the targeted therapy group, and 21 in the combined therapy group. The progression-free survival of the combined therapy group was better than the other two groups (P=0.045). ConclusionThere is a correlation between the imaging features of LCCA and pathological aggressiveness. Compared to postoperative targeted therapy or chemotherapy alone, postoperative chemotherapy combined with targeted therapy can improve the progression-free survival of LCCA patients.
Objective To investigate the effectiveness of cementless total hip arthroplasty (THA) in treatment of avascular necrosis of the femoral head (ANFH) in patients with human immunodeficiency virus (HIV) infection. Methods The clinical data of 22 patients (35 hips) with HIV infection and ANFH (positive group), who were treated with cementless THA between February 2014 and January 2017, was retrospectively analyzed. Tirty-three cases (43 hips) without HIV infection, who were treated with cementless THA during the same period, were collected as control (negative group). There were significant differences in the age, gender, incidence of bilateral ANFH, and disease duration between 2 groups (P<0.05). There was no significant difference in the Ficat stage of ANFH between 2 groups (P>0.05). The operation time, intraoperative blood loss, rate of blood transfusion, postoperative complications, and hospitalization time were recorded. The hip joint function was evaluated by Harris score and X-ray film was performed to observe the position of the prosthesis. Results The follow-up time was 13-24 months (mean, 20.2 months) in positive group and 14-25 months (mean, 21.6 months) in negative group. The operation time of negative group was significantly shorter than that of positive group (t=3.677, P=0.001). However, there was no significant difference in intraoperative blood loss, rate of blood transfusion, and hospitalization time between 2 groups (P>0.05). There was no significant difference in Harris score between 2 groups before operation and at 1, 3, 6, and 12 months after operation (P>0.05). There were 2 cases of superficial infection of incision and 1 case of pulmonary infection during hospitalization in positive group, and 1 case of superficial infection of incision and 1 case of venous thrombosis of lower extremity in negative group. No death or loosening and sinking of the prosthesis occurred in both groups during follow-up. Conclusion Cementless THA is a safe and effective method for ANFH in patients with HIV infection.
