Objective To evaluate the effects of neoadjuvant long-course chemoradiotherapy (CRT), neoadjuvant short-course radiotherapy (SCRT), and total neoadjuvant treatment (TNT) on chemoradiotherapy related complications and perioperative safety in mid-low rectal cancer patients. Methods The clinical data of 63 rectal cancer patients who received neoadjuvant (chemo) radiotherapies and surgery treatment in West China Hospital from Jul. 2014 to Feb. 2016 were retrospectively analyzed. According to the neoadjuvant regimen, the patients were divided into CRT group (n=15), SCRT group (n=30), and TNT group (n=18), and then the effects of these 3 kinds of neoadjuvant regimen on chemoradiotherapy related complications and perioperative safety were compared. Results ① Chemoradiotherapy related complications: among all the included 63 patients, 29 patients (46.0%) occurred chemoradiotherapy related complications, including radiation enteritis in 9 patients and bone marrow suppression in 25 patients. There were significant differences in the overall incidence of chemoradiotherapy related complications, incidence of radiation enteritis and bone marrow suppression (P≤0.001). The overall incidence of chemoradiotherapy related complications and incidence of bone marrow suppression of SCRT group were lower. ② Perioperative safety: no significant differences were found in the incidence of surgical complications, incidence of specific surgical complication, operation duration, intraoperative blood loss, and postoperative flatus time (P<0.05), but there was significant difference in the postoperative hospital stay among 3 groups (P=0.033), the postoperative hospital stay of SCRT group was shorter. Conclusion CRT, SCRT, and TNT have similar effect on the safety in the mid-low rectal cancer patients, which suggests that SCRT is worthy of further research and promotion.
Objective To evaluate the feasibility, safety, and early effectiveness of percutaneous endoscopic thoracic spine surgery via the trench technique for ventral decompression in central calcified thoracic disc herniation (CCTDH) and thoracic ossification of the posterior longitudinal ligament (T-OPLL). MethodsSeven patients with single-segment CCTDH or T-OPLL admitted between June 2017 and May 2020 and meeting the selection criteria were retrospectively analyzed. There were 3 males and 4 females with an average age of 51.7 years ranging from 41 to 62 years. There were 2 patients with T-OPLL (T1, 2 in 2 cases) and 5 patients with CCTDH (T1, 2 in 1 case, T7, 8 in 1 case, T10, 11 in 2 cases, T11, 12 in 1 case). Five patients with thoracic axial pain and intercostal neuralgia had a preoperative visual analogue scale (VAS) score of 6.0 (5.0, 6.5), and 7 patients had a preoperative Japanese Orthopaedic Association (JOA) score of 21 (21.0, 22.0). Transforaminal approach was used in 4 cases and transpedicular approach in 3 cases. Ventral decompression of thoracic spinal cord was performed by thoracic endoscopy combined with trench technique. The operation time, intraoperative blood loss, postoperative hospital stay, and postoperative complications were recorded. Thoracic spine CT and MRI were performed preoperatively and postoperatively to evaluate the surgical decompression, VAS score was used to evaluate the pain of thoracic back and lower limbs, and JOA score was used to evaluate the functional recovery. Modified MacNab criteria was used to evaluate the effectiveness. ResultsAll surgeries were successfully completed. The operation time ranged from 60 to 100 minutes, with an average of 80.4 minutes; the intraoperative blood loss ranged from 40 to 75 mL, with an average of 57.1 mL; the postoperative hospital stay ranged from 4 to 7 days, with an average of 5.4 days. CT and MRI examinations indicated that the decompression was adequate. All 7 patients were followed up 3-22 months, with an average of 13.3 months. One case developed postoperative wound infection, and 1 case developed pneumonia; the remaining patients did not have any complications such as wound infection or cerebrospinal fluid leakage. Five patients with thoracic axial pain and intercostal neuralgia had VAS scores of 2.0 (1.5, 2.5) at 1 day after operation and 2.0 (1.0, 2.0) at last follow-up, both of which were significantly lower than the preoperative scores (P<0.05). At 1 day after operation, the JOA scores for all 7 patients were 22.0 (21.0, 24.0), which showed no significant difference compared to the preoperative score (P>0.05); however, at last follow-up, the score improved to 24.0 (24.0, 26.0), which was significant compared to the preoperative scores (P<0.05). At last follow-up, the effectiveness was assessed using the modified MacNab criteria, the results were excellent in 2 cases, good in 3 cases, fair in 2 cases, and the excellent and good rate was 71.4%.ConclusionUsing the trench technique, percutaneous endoscopic thoracic spine surgery can achieve the ventral decompression in CCTDH and T-OPLL, providing a new approach for surgical treatment of CCTDH and T-OPLL.
Objective To develop tailored treatment regimens for a patient with simultaneous liver metastasis of rectal cancer. Methods Considering the patient's specific condition of different teatment stage, the specialists of oncology, imaging, gastroenterology, hepatic surgery, and radiotherapy conduct multidisciplinary consultation. Results After hepatic metastatic tumor was resected, 4 cycles of XELOX chemotherapy combined with radiotherapy, tumor recurrence did not found in the liver. After resection of rectal cancer, the patient received 6 cycles of XELOX. The CEA and the thoracic, abdominal CT and pelvic MRI were reviewed 9 months after operation and no recurrence of the tumor was found. Conclusion The MDT mechanism can provide individualized treatment for patients with advanced rectal cancer and benefit these patients.

Methods From November 2004 to April 2008, 21 patients who had a poor response after conservative treatment for their cervical disc degeneration underwent the single level Bryan disc replacement. Before the operation and 1, 6, 12, 18, and 24 months after the operation, all patients were evaluated by neck disable index (NDI), subjective symptom scale, visual analogue scale (VAS) and Odom score. The radiological examinations included X-ray, CT scan and MRI. Results Operations were successfully executed in 21 patients. All patients had obeyed the follow-up visiting at the expected time in the next two years after the operation. Patients′ symptom scale, VAS for neck pain, VAS for arm pain, NDI were 2.80±0.42, 4.62±1.84, 5.01±1.79, and 22.60±4.88, respectively before the operation and significantly decreased to 0.20±0.42, 1.01±0.56, 0.82±0.24, and 4.30±1.25, respectively at the end of the follow-up. All patients had good or higher score of the Odom score. The ymptoms were completely relieved in eight patients (38.1%). The mean operation time was (110.5±42.6) minutes, the average blood loss was (166.0±108.8) mL. The normal motion of the artificial disc was observed. No cervical instability was observed. Two prosthesis migrated slightly. Conclusion Single segmental Bryan disc replacement is safe and effective on the cervical disc degeneration. The two-year follow-up reveales a satisfied clinical outcome.
Against the backdrop of medical digital transformation, West China Hospital of Sichuan University has conducted a 30-year exploration and practice of colorectal cancer data engineering. This study focuses on the integration of special disease digitization and value-based healthcare, achieving standardized management and in-depth mining of colorectal cancer diagnosis and treatment data through constructing a full-life cycle data governance system, multi-center data platform, and intelligent application scenarios (such as clinical decision support systems). The practical results show that this data engineering has formed a specialized disease database containing more than 9 500 cases of structured data, and promoted the collaborative development of the entire chain of “production–study–research–business–government”, providing a learnable digital paradigm for improving diagnostic and treatment accuracy and optimizing medical resource allocation. The study indicates that special disease digitization is a key path to achieving value-based healthcare, and its experience in data standardization and medical-engineering cross-innovation is of reference significance for other disease fields.
