Prognostic Variables for Local Recurrence and Overall Survival after Surgical Treatment of Sacral Chordoma: An Analysis from AOSpine Tumor Knowledge Forum Primary Spinal Tumor Retrospective Database

Purpose: To perform a systematic review and meta-analysis on the outcome of surgical treatment for isolated local recurrence of pancreatic cancer. Methods: A systematic review and meta-analysis based on Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines was conducted in PubMed, Scopus, and Web of Science. Results: Six studies concerning 431 patients with recurrent pancreatic cancer met the inclusion criteria and were included in the analysis: 176 underwent redo surgery, and 255 received non-surgical treatments. Overall survival and post-recurrence survival were significantly longer in the re-resected group (ratio of means (ROM) 1.99; 95% confidence interval (CI), 1.54–2.56, I2 = 75.89%, p = 0.006, and ROM = 2.05; 95% CI, 1.48–2.83, I2 = 76.39%, p = 0.002, respectively) with a median overall survival benefit of 28.7 months (mean difference (MD) 28.7; 95% CI, 10.3–47.0, I2 = 89.27%, p < 0.001) and median survival benefit of 15.2 months after re-resection (MD 15.2; 95% CI, 8.6–21.8, I2 = 58.22%, p = 0.048). Conclusion: Resection of isolated pancreatic cancer recurrences is safe and feasible and may offer a survival benefit. Selection of patients and assessment of time and site of recurrence are mandatory.

Abstract Objective To evaluate the survival outcomes of patients with local recurrence after radical nephrectomy (RN) and to test the effect of surgery, as monotherapy or in combination with systemic treatment, on cancer-specific mortality (CSM). Methods Patients with local recurrence after RN were abstracted from an international dataset. The primary outcome was CSM. Cox’s proportional hazard models tested the main predictors of CSM. Kaplan–Meier method estimates the 3-year survival rates. Results Overall, 96 patients were included. Of these, 44 (45.8%) were metastatic at the time of recurrence. The median time to recurrence after RN was 14.5 months. The 3-year cancer-specific survival rates after local recurrence were 92.3% (± 7.4%) for those who were treated with surgery and systemic therapy, 63.2% (± 13.2%) for those who only underwent surgery, 22.7% (± 0.9%) for those who only received systemic therapy and 20.5% (± 10.4%) for those who received no treatment (p < 0.001). Receiving only medical treatment (HR: 5.40, 95% CI 2.06–14.15, p = 0.001) or no treatment (HR: 5.63, 95% CI 2.21–14.92, p = 0.001) were both independently associated with higher CSM rates, even after multivariable adjustment. Following surgical treatment of local recurrence 8 (16.0%) patients reported complications, and 2/8 were graded as Clavien–Dindo ≥ 3. Conclusions Surgical treatment of local recurrence after RN, when feasible, should be offered to patients. Moreover, its association with a systemic treatment seems to warrantee adjunctive advantages in terms of survival, even in the presence of metastases.

Abstract Background To explore the factors that affect the prognosis of overall survival (OS) and cancer-specific survival (CSS) of patients with stage IIIC1 cervical cancer and establish nomogram models to predict this prognosis. Methods Data from patients in the Surveil-lance, Epidemiology, and End Results (SEER) programme meeting the inclusion criteria were classified into a training group, and validation data were obtained from the First Affiliated Hospital of Anhui Medical University from 2010 to 2019. The incidence, Kaplan-Meier curves, OS and CSS of patients with stage IIIC1 cervical cancer in the training group were evaluated. Nomograms were established according to the results of univariate and multivariate Cox regression models. Harrell’s C-index, calibration plots, receiver operating characteristic (ROC) curves and decision-curve analysis (DCA) were calculated to validate the prediction models. Results The incidence of pelvic lymph node metastasis, a high-risk factor for the prognosis of cervical cancer, decreased slightly over time. Eight independent prognostic variables were identified for OS, including age, race, marriage status, histology, extension range, tumour size, radiotherapy and surgery, but only seven were identified for CSS, with marriage status excluded. Nomograms of OS and CSS were established based on the results. The C-indexes for the nomograms of OS and CSS were 0.687 and 0.692, respectively, using random sampling of SEER data sets and 0.701 and 0.735, respectively, using random sampling of external data sets. The AUCs for the nomogram of OS were 0.708 and 0.705 for the SEER data sets and 0.750 and 0.750 for the external data sets, respectively. In addition, AUCs of 0.707 and 0.709 were obtained for the nomogram of CSS when validated using SEER data sets, and 0.788 and 0.785 when validated using external data sets. Calibration plots for the nomograms were almost identical to the actual observations. The DCA also indicated the value of the two models. Conclusions Eight independent prognostic variables were identified for OS. The same factors predicted CSS, with the exception of the marriage status. Both OS and CSS nomograms had good predictive and clinical application value after validation. Notably, tumour size had the largest contribution to the OS and CSS nomograms.

Purpose This study is aimed to evaluate the clinical outcomes of surgical treatment for nonagenarian patients with colorectal cancer. Methods This retrospective single-center study included patients diagnosed with colorectal cancer at the age of ≥90 years between 2004 and 2018. Patient demographics were compared between the operation and nonoperation groups (NOG). Perioperative outcomes, histopathological outcomes, and postoperative complications were evaluated. Overall survival was analyzed using Kaplan-Meier methods and log-rank test. Results A total of 31 patients were included (16 men and 15 women), and the median age was 91 (range: 90‐96) years. The number of patients who underwent surgery and who received nonoperative management was 20 and 11, respectively. No statistical differences in baseline demographics were observed between both groups. None of these patients were treated with perioperative chemotherapy or radiotherapy. Surgery comprised 18 (90.0%) colectomies and 2 (10.0%) transanal excisions. Short-term (≤30 days) and long-term (31‐90 days) postoperative complications occurred in 7 (35.0%) and 4 (20.0%) patients, respectively. No complications needed reoperation, such as anastomosis leakage or bleeding. No postoperative mortality occurred within 30 days: 90-day postoperative mortality occurred in two patients (10.0%), respectively. The median overall survival of the operation group was 31.6 (95% confidence interval: 26.7‐36.5) and that of NOG was 12.5 months (95% CI: 2.4‐22.6) ( P = 0.012). Conclusion Surgical treatment can be considered in carefully selected nonagenarian patients with colorectal cancer in terms of acceptable postoperative morbidity, with better overall survival than the nonsurgical treatment.

Abstract Purpose Chordomas are rare tumors with an annual incidence of approximately one per million. Chordomas rarely metastasize but show a high local recurrence rate. Therefore, these patients present a major clinical challenge, and there is a paucity of the literature regarding the outcome after revision surgery of cervical spine chordomas. Available studies suggest a significantly worse outcome in revision scenarios. The purpose of this study is to analyze the survival rate, and complications of patients that underwent revision surgery for local recurrence or incomplete resection of chordoma at the craniocervical junction or at the cervical spine. Methods 24 consecutive patients that underwent revision surgery for cervical spine chordoma remnants or recurrence at a single center were reviewed retrospectively. We analyzed patient-specific surgical treatment strategies, complications, and outcome. Kaplan–Meier estimator was used to analyze five-year overall survival. Results Gross total resection was achieved in 17 cases. Seven patients developed dehiscence of the pharyngeal wall, being the most common long-term complication. No instability was observed. Postoperatively, four patients received proton beam radiotherapy and 12 patients had combined photon and proton beam radiotherapy. The five-year overall survival rate was 72.6%. Conclusion With thorough preoperative planning, appropriate surgical techniques, and the addition of adjuvant radiotherapy, results similar to those in primary surgery can be achieved.
