Application of ultrasound-guided percutaneous radiofrequency ablation in treatment of liver cancer.

Objective To investigate the therapeutic efficacy and its influencing factors of ultrasoundguided percutaneous radiofrequency ablation (PRFA) in the treatment of liver carcinoma. Methods With a temperature-controlled multi-electrode needle, ultrasound-guided PRFA was employed to treat forty-seven patients with 67 tumor nodules, with a diameterof 2.6 ± 1.1 cm (1.0 - 5.5 cm). Results A complete ablation (CA) rate of 80. 6% was achieved in the present series, with a CA rate of 91.7 % in the tumors ≤3 cm in diameter,75. 0% in tumors from 3.1 to 4. 0 cm,and 14. 3% in tumors 】4 cm. The CA rate was significantly greater in tumors with a temperature rising up to 70℃ within the initial 2 minutes at ablation as compared with that longer than 2 minutes (P 【 0.05). A markedly higher CA rate was obtained in tumors with an ablation-maintaining temperature of over 80℃ than that between 70℃ and 80℃ ( P 【 0. 01). All patients were followed up with a mean time of 11. 3 months. The local recurrence rate was 9.3% (5/

Primary experience of video-assisted rigid laser bronchoscopy in treatment of tracheobronchial tumors

To review the primary experience of video-assisted rigid laser bronchoscopy in the treatment of tracheobronchial tumors.Methods From Sep.2002 to Nov.2004,13 patients (15 procedures) with tracheobronchial tumors were treated with video-assisted rigid bronchoscope.Benign tumors with small pedicles were removed directly.For benign tumors with wide pedicles or tumors extending beyond the wall of air-way,total enucleating through thoracotomy were employed.In cases with malignant tumors,stenosis or obstructions were relieved by implantation of stent or cautering with electric argoulaser knife.For malignant but resectable primary tumors of trachea and main bronchi,rigid bronchoscopy might serve as a preparation of radical resection.Results Of the 5 patients with benign tumors,4 received endoscopic total resection and 1 were conversed into thoracotomy.For the 8 malignant cases,3 received stent implantation,2 had palliative ablation 3 got curative resections through thoracotomy.No peri-operative complications or death occurred in this group.Conclusion Total resection of benign tracheobronchial tumors or palliative therapy for tracheobronchial malignant stenosis or preparation of radical resection can be performed safely and efficiently by video-assisted rigid bronchoscopy.5 refs.

Clinical Study of Puerarin in Treatment of Patients with Unstable Angina

Objective: To observe the clinical efficacy of puerarin in treating patients with unstable angina (UA). Methods: Frequency of angina events, consumed doses of nitrates, heart rate, blood pressure, rest electrocardiogram (ECG) and myocardial oxygen consumption were observed before or after drug therapy in puerarin group and control group respectively. Results: The puerarin group not only showed more effective than that in control group in reducing frequency of angina events and consumed doses of nitrates and improving abnormal rest ECG, but also appeared to be preferable to the control group in reducing myocardial oxygen consumption and increasing exercise duration (P < 0. 05 ). Conclusion: Puerarin is a safe and effective drug in treating patients with UA.Original article on CJIM(Chin) 1998; 18(5): 282

Artificial intelligence in rectal cancer:What is the future?

Colorectal cancer(CRC)is the third most prevalent cancer in both men and women,and it is the second leading cause of cancer-related deaths globally.Around 60%-70%of CRC patients are diagnosed at advanced stages,with nearly 20%having liver metastases.It is noteworthy that the 5-year survival rates decline significantly from 80%-90%for localized disease to a mere 10%-15%for patients with metastasis at the time of diagnosis.Early diagnosis,appropriate therapeutic strategy,accurate assessment of treatment response,and prognostication is essential for better outcome.There has been significant technological development in the last couple of decades to improve the outcome of rectal cancer including Artificial intelligence(AI).AI is a broad term used to describe the study of machines that mimic human intelligence,such as perceiving the environment,drawing logical conclusions from observations,and performing complex tasks.At present AI has demonstrated a promising role in early diagnosis,prognosis,and treatment outcomes for patients with rectal cancer,a limited role in surgical decision making,and had a bright future.

Consultation, Diagnosis and Treatment Delays for Breast Cancer among Patients Followed up at the YaoundéGeneral Hospital, Cameroon

Introduction: Breast cancer is often diagnosed at an advanced stage in Cameroon. The objective was to analyse consultation, diagnosis and treatment delays for breast cancer among patients followed up at the Yaoundé General Hospital (YGH) in Cameroon. Materials and Methods: This was a cross-sectional study carried out from the files of patients followed up for breast cancer at the YGH from January 1, 2014 to April 30, 2018. A total of 183 patients were included. We measured time elapsed between the awareness of first signs of disease and the initial consultation (consultation delays), time lapse between the initial consultation and pathological diagnosis of breast cancer (diagnosis delays), interval between pathological diagnosis and treatment onset (treatment delays), time elapsed between the initial consultation and management (health system delays) and time elapsed from awareness of first signs of disease to treatment onset (overall delays). Results: The delays (median, IIQ) were: (5.1 months;IIQ: 1.7 - 12.4), (25 days;IIQ: 10 - 67), (27 days;IIQ: 13 - 63), (2.2 months;IIQ: 1.2 - 5.8) and (9.9 months;IIQ: 4.4 - 17.6) respectively for consultation, diagnosis, treatment, health system and overall delays. The risks associated with a delay in initial consultation of greater than 3 months were (OR;95% CI): unschooled patients (2.01;1.66 - 2.40);monthly income below the minimum wage (2.70;1.81 - 5.96);unemployment (2.14;1.02 - 3.24) and absence of a family history of cancer (2.44;1.66 - 6.10). The main reasons for a late first consultation were: ignorance (60.2%), financial challenges (17.6%) and a preference for alternative treatment (11.1%). Conclusion: The consultation, diagnosis and treatment delays for breast cancer are very often long in our setting than those reported in developed countries. Both patients’ and institutional factors are demonstrated. There is a need to increase public awareness on the value of early diagnosis of breast cancer. Also, health system should be improved to enable early diagnosis and treatment of this affection.
