Prostate cancer represents a prevalent malignancy within the male genitourinary system. In recent years, its incidence in China has gradually increased, becoming a significant public health issue. While early detection correlates strongly with improved prognosis, the majority of newly diagnosed prostate cancer patients in China are already in intermediate or advanced stages, precluding curative-intent interventions and contributing to marked survival disparities. The progression of prostate cancer is lengthy, typically encompassing diagnosis, treatment, progression, metastasis, and death, accompanied by a decline in quality of life. Personalized treatment plans should be developed based on the disease stage and patient preferences. In non-metastatic prostate cancer, where the tumor is confined to the prostate, surgery and radiotherapy are the primary treatments, supplemented by neoadjuvant and adjuvant therapies to delay metastasis. For metastatic prostate cancer, systemic therapy is prioritized to prolong survival. In metastatic hormone-sensitive prostate cancer, controlling androgen levels is crucial, while treatment options for metastatic castration resistant prostate cancer are relatively limited, necessitating individualized and precise treatment. During prostate cancer management, prostate-specific antigen levels are closely linked to prognosis and require monitoring. Bone metastasis, the most common site in prostate cancer patients, often triggers skeletal-related events, demanding effective prevention and management. Treatment-related adverse reactions are also a clinical challenge, requiring balanced risk-benefit assessments and judicious drug selection to preserve quality of life. Rapid advancements in screening technologies, surgical innovations, drug development, and China-specific epidemiological factors further complicate decision-making in holistic prostate cancer management. To optimize the standardization of prostate cancer diagnosis and treatment in China, the Genitourinary Oncology Committee of Chinese Anti-cancer Association synthesized global guidelines, clinical evidence and clinical expertise, and addressed critical challenges in the whole-course management of prostate cancer to formulate a multidisciplinary consensus. The expert consensus on whole-course management of prostate cancer (2025 edition) establishes standardized protocols to guide clinical practice, improve treatment outcomes, and enhance patient quality of life.

With the extension of survival period and the improvement of imaging technology, the incidence of bone metastasis from colorectal cancer gradually increases. Therefore, the early diagnosis and treatment of bone metastasis should not be neglected while the primary lesion was controlled.Currently, the available evidence for bone metastasis from colorectal cancer is very limited. In this article, the Chinese Society of Colorectal Cancer organized multi-disciplinary experts to integrate the relevant studies worldwide and combine with clinical practice, focused on the issues and controversies about clinical characteristics, diagnosis and treatment, and follow-up of bone metastatic patients with colorectal cancer.After discussion and voting, Chinese expert consensus on multidisciplinary treatment of bone metastasis from colorectal cancer (2020 version) was formed. This consensus could provide clinicians with more detailed multidisciplinary treatment strategies for bone metastasis from colorectal cancer.

BACKGROUND: Lung cancer is the leading cause of cancer-related deaths, patients with non-small cell lung cancer (NSCLC) usually have distant metastases, such as bone metastasis, brain metastasis, and lung metastasis. The purpose of this study was to explore the risk factors for bone metastasis in NSCLC patients. METHODS: A total of 176 cases of NSCLC were selected from May 2009 to May 2011, and patients were divided into two groups, namely the bone metastasis group and non-bone metastasis group. The general clinicopathological data of the two groups and analyzing the independent risk factors of bone metastasis were compared. RESULTS: In the general clinicopathological data of NSCLC patients. The thrombus or not and tumor-node-metastasis (TNM) stage were closely related to the occurrence of bone metastasis, and were statistically significant (all P<0.01). Prothrombin time, activated partial thromboplastin time, Fibrinogen, thrombin time, blood platelet, D-Dimer and alkaline phosphatase have significantly difference between the two groups (all P<0.05). Logistic regression analysis showed that fibrinogen, activated partial thromboplast in time, alkaline phosphatase, T4 phase, N3 phase and d-dimer were independent risk factors for bone metastasis in NSCLC patients. CONCLUSIONS Fibrinogen, alkaline phosphatase, T3, N2 stage and D-Dimer is the independent risk factors of bone metastases in patients with NSCLC.

OBJECTIVETo investigate the correlation between a diverse of clinical factors and bone metastases of prostate cancer.

METHODSThe clinical data of 80 patients with prostate cancer were collected and analyzed. The correlations of age, alkaline phosphotase (ALP), prostate specific antigen (PSA), erythrocyte sedimentation rate (ESR), Gleason score, and expressions of androgen receptor (AR) and Ki-67 with bone metastases were analyzed by one-way ANOVA and Logistic regression analysis. The cutoff value, sensitivity and specificity of the independent correlation factors were calculated.

RESULTSForty-five of the 80 patients (56%) were found to have bone metastasis, who had significantly older age and higher levels of ALP, PSA, ESR, Gleason score, and expressions of AR and Ki-67 than those without bone metastasis (P<0.05). Logistic regression analysis identified PSA, Gleason score and AR expression as independent factors correlated with bone metastasis with OR (95% CI) of 1.005 (1.001, 1.009) (P=0.008), 5.356 (1.431, 20.039) (P=0.013), and 18.594 (2.460, 140.524) (P=0.005), respectively. The cutoff values of PSA, Gleason Score and AR were 67.1 ng/ml, 7.5, and 2.5, respectively; their sensitivities were 55.6%, 75.6%, and 84.0% for predicting bone metastasis with specificities of 97.1%, 82.9%, and 91.4%, respectively.

CONCLUSIONOf the factors analyzed, PSA, Gleason score and AR expression, but not age, ALP, PSA, ESR, or Ki-67 expression, are the predictive factors of bone metastasis of prostate cancer.

The bone is a common site for metastasis in hepatocellular carcinoma (HCC). However, bone marrow metastasis from HCC is rarely reported, and its frequency is unclear. Here we report a rare case of bone marrow metastasis that presented as bicytopenia originating from HCC without bone metastasis. A 58-year-old man was admitted for investigation of a liver mass with extensive lymph node enlargement that was detected when examining his general weakness and weight loss. Laboratory findings revealed anemia, thrombocytopenia, mild elevated liver enzymes, normal prothrombin time percentage and high levels of tumor markers (α-fetoprotein and des-γ-carboxyprothrombin). Abdominal computed tomography showed multiple enhanced masses in the liver and multiple enlarged lymph nodes in the abdomen. A bone marrow biopsy revealed only a few normal hematopoietic cells and abundant tumor cells. Despite its rarity, bone marrow metastasis should always be suspected in HCC patients even if accompanied by cirrhosis.

STUDY DESIGN: Retrospective study. PURPOSE: To note the magnetic resonance imaging (MRI) differences between pathologically proven cases of atypical spinal tuberculosis and spinal metastasis in 40 cases. OVERVIEW OF LITERATURE: Spinal tuberculosis, or Pott's spine, constitutes less than 1% of all cases of tuberculosis and can be associated with a neurologic deficit. Breast, prostate and lung cancer are responsible for more than 80% of metastatic bone disease cases, and spine is the most common site of bone metastasis. Thus, early diagnosis and prompt management of these pathologies are essential in preventing various complications. METHODS: We retrospectively reviewed 40 cases of atypical tuberculosis and metastasis affecting the spine from the year 2012 to 2014, with 20 cases each that were proven by histopathological examination. MR imaging was performed on 1.5 T MR-Scanner (Magnetom Avanto, Siemens) utilizing standard surface coils of spine with contrast injection. Chi-square test was used for determining the statistical significance and p-values were calculated. RESULTS: The most common site of involvement was the thoracic spine, seen in 85% cases of metastasis and 65% cases of Pott's spine (p=0.144). The mean age of patients with tubercular spine was found to be 40 years and that of metastatic spine was 56 years. The following MR imaging findings showed statistical significance (p<0.05): combined vertebral body and posterior elements involvement, skip lesions, solitary lesion, intra-spinal lesions, concentric collapse, abscess formation and syrinx formation. CONCLUSIONS: Tuberculosis should be considered in the differential diagnosis of various spinal lesions including metastasis, fungal spondylodiskitis, sarcoidosis and lymphoma, particularly in endemic countries. Spinal tuberculosis is considered one of the great mimickers of disease as it could present in a variety of typical and atypical patterns, so proper imaging must be performed in order to facilitate appropriate treatment.

OBJECTIVETo explore the clinicopathologic features and imaging diagnosis of 17 cases of liposclerosing myxofibrous tumor (LSMFT) and to discuss the mechanism of the disease.

METHODSCases of LSMFT diagnosed in 2014 were included in this retrospective study. The clinicopathologic features and imaging findings were evaluated.

RESULTSThere were 17 cases of LSMFT, occurring in 11 men and 6 women with a mean age of 46 years (range, 26-67 years). Patients were asymptomatic or presented with pain localized over the lesions. Most (13/17) lesions were located in the intertrochanteric region. Radiographs showed well-defined and often extensively sclerotic margin. MRI showed the lesions to be relatively heterogeneous on T1W, and heterogeneous with high signal intensity on T2W with fat suppression. Microscopically, LSMFT was characterized by a complex mixture of histologic elements, including myxofibrous and collagen tissues, lipomatous areas, xanthoma cells, calcification, irregular ossification and pseudo-Paget's bone.

CONCLUSIONSLSMFT is a benign fibro-ossesous lesion with unique imaging characteristics and histologic features, occurring preferentially in some locations. It might represent end-stage degenerative changes in other benign bone lesions such as fibrous dysplasia, simple bone cyst and intraosseous lipoma secondary to trauma from forces and ischemic bone injury exerted on the intertrochanteric region of the femur.

A 59-year-old man was admitted to the Department of Ear, Nose and Throat with a complaint of six-month history of left facial numbness and toothache. There was no special previous medical history in addition to smoking. No obvious abnormality in routine electrocardiogram, chest X-ray, abdominal B ultrasound were found. (1) CT scans showed heterogeneous shadows in maxillary sinus with the lesions on the left max- illary bone and evidently destruction of alveolar bone. The histopathological examination revealed bone tissue which was partly covered by an intact adenocarcinoma cell. (2) Immunohistochemical staining foe CK7, CD117, thyroid transcription factor-1, and novel aspartic proteinase A were positive and thus compatible with metastatic lung adenocarcinoma. (3) Chest CT scans showed a 1 cm x 2 cm mass on the superior lobe of the left lung, with destruction of sternum and rib, confirming that the lesions in the paranasal sinuses were lung cancer metastases. Therefore, this patient conclusively diagnosed as lung adenocarcinoma with multiple bone metastases.
