Effect of Adjuvant Chemotherapy in Stage III Cervical Cancer Patients Treated With Concurrent Chemoradiation: A Multicenter Study

Introduction: A significant proportion of cervical cancer (CC) patients are diagnosed at a locally advanced stage. Concurrent chemoradiotherapy (CCRT) is the cornerstone of treatment for patients with locally advanced CC. However, the role of adjuvant chemotherapy (AC) after CCRT is controversial. In this study, we analyzed the efficacy of AC after CCRT in stage III CC patients. Methods: We performed a multicenter, retrospective analysis of 139 FIGO stage III CC patients treated with CCRT of whom 45.3% received AC. Our goal was to determine the impact of AC on survival in these patients. Results: Five-year progression-free survival was 37.5% and 16% in patients receiving CCRT with and without AC, respectively (p=0.008). Median PFS was 30.9 months (CI 95 %14.8-46.9) and 16.6 months (CI 95% 9.3-23.9) in patients receiving CCRT with and without AC, respectively. Five-year overall survival was 78.2% and 28.4% in patients receiving CCRT with and without AC, respectively (p<0.001). Median OS was 132.2 months (CI 95, %66.5-197.8) and 34.9 months (CI 95% 23.1-46.7) in patients receiving CCRT with and in without AC, respectively. Conclusion: Our study suggests that AC provides OS and PFS benefit in stage III CC patients. Larger studies are needed to identify subgroups of patients who would benefit from AC.

Postoperative Adjuvant Chemotherapy Cancel Out the Negative Survival Impact on Stage II/III Gastric Cancer Patients With Postoperative Complications

Purpose The potential additive influence of adjuvant chemotherapy (AC) on prognosis of patients with stage II/III gastric cancer (GC) who experienced complications after radical surgery is unclear.Methods The whole group was divided into a postoperative complication (PC) group and a postoperative non-complication (NPC) group, and the overall survival (OS) rate, recurrence-free survival (RFS) rate and recurrence rate were compared between the two groups of patients. Results A total of 1563 patients between January 2010 and December 2015 in our center were included in this analysis. There were 268 patients (17.14%) in the PC group and 1295 patients (82.86%) in the NPC group. The 5-year OS rate of the PC group was 55.2%, the NPC group was 63.3%; and the 5-year RFS rate of the PC group was 53.7%, the non-PC group was 58.8%. Recurrence patterns showed no significant difference between the two group (all p>0.05). Adjuvant chemotherapy (AC) significantly improved the OS and RFS rates of patients with and without PCs (both p<0.05), and it showed no significant difference between the PC group and the NPC group who received AC (both p> 0.05). Stratified analysis showed that AC only improve the OS or RFS rates of stage III patients (both p<0.05). Further stratified analysis of the time interval (TI) from operation to initiation of AC in the PC group showed that a TI after 6 weeks (≥6eeks) improved only the OS and RFS rates of stage III patients, while when a TI within 6 weeks (＜6weeks), a benefit was observed in stage II and III patients (both p<0.05).Conclusion AC can abolish the negative effect of PCs on the long-term survival of patients with stage III GC; for stage II patients, the above offset effect is affected by the TI. Delaying AC initiation after 6 weeks may not improve the survival of patients experienced stage II GC with complications.

Detection of Mitochondrial DNA Copy Number in Plasma Exosomes of Patients with Non-small Cell Lung Cancer

For the prevalence of lung cancer and its poor diagnosis, the seeking of the efficient biomarkers for this disease is an urgent requirement, especially from non-invasive samples such as plasma. The mitochondria DNA (mtDNA) copy number change has been evaluated as a potential indicator of cancer risk, however, there have been few studies regarding mtDNA in plasma derived exosomes. In this study, the mtDNA copy number was measured on 29 plasma exosome samples of patients with non-small cell lung cancer (NSCLC) and 29 plasma exosome samples of cancer-free controls by real-time PCR assay, then being statistically analyzed to evaluate the relationship between these figures and several pathological features of NSCLC patients. As the results, the existence of mtDNA in exosomes isolated from plasma was detected through PCR assay using primers covering most of the mtDNA length. The relative mtDNA copy numbers determined in the exosomes of the disease and control groups were 1619.1 ± 2589.0 and 1207.0 ± 1550.0, respectively, whereas these values in two disease stages were 783.6 ± 759.3 (stage I-II) and 2647.0 ± 3584.0 (stage III-IV). Comparing among these groups, the difference was only statistically significant between the disease groups of stage I-II and stage III-IV (p<0.05), the group of stage III-IV and the control group (p<0.05). Indeed, the mtDNA copy number is associated with tumor stage and stage N (p<0.05). On the other aspect, the smoking habit of NSCLC patients could be an underlying reason behind the alteration in mtDNA copy number in the plasma exosomes. In short, our study demonstrates that the mtDNA copy number in exosomes resourced from plasma could be a potential biomarker for the detection and prognosis of NSCLC.

Therapeutic Challenges in Patients with Gynecologic Carcinosarcomas: Analysis of a Multicenter National Cohort Study from the French Prospective TMRG Network

Background: Gynecological carcinosarcomas are rare and aggressive diseases, with a poor prognosis. The rarity of these tumors explains the lack of robust and specific data available in the literature. The objective of this study was to investigate the impact of initial adjuvant treatment and recurrent therapeutic strategies. Patients and methods: A multicentric cohort study within the French national prospective Rare Malignant Gynecological Tumors (TMRG) network was conducted. Data from all included carcinosarcomas diagnosed between 2011 and 2018 were retrospectively collected. Results: 425 cases of uterine and ovarian carcinosarcomas (n = 313 and n = 112, respectively) were collected and analyzed from 12 participating centers. At diagnosis, 140 patients (48%) had a FIGO stage III–IV uterine carcinosarcoma (UCS) and 88 patients (83%) had an advanced ovarian carcinosarcoma (OCS) (FIGO stage ≥ III). Two hundred sixty-seven patients (63%) received adjuvant chemotherapy, most preferably carboplatin-paclitaxel regimen (n = 227, 86%). After a median follow-up of 47.4 months, the median progression-free survival (mPFS) was 15.1 months (95% CI 12.3–20.6) and 14.8 months (95% CI 13.1–17.1) for OCS and UCS, respectively. The median overall survival for OCS and UCS was 37.1 months (95% CI 22.2–49.2) and 30.6 months (95% CI 24.1–40.9), respectively. With adjuvant chemotherapy followed by radiotherapy, mPFS was 41.0 months (95% CI 17.0–NR) and 18.9 months (95% CI 14.0–45.6) for UCS stages I–II and stages III–IV, respectively. In the early stage UCS subgroup (i.e., stage IA, n = 86, 30%), mPFS for patients treated with adjuvant chemotherapy (n = 24) was not reached (95% CI 22.2–NR), while mPFS for untreated patients (n = 62) was 19.9 months (95% IC 13.9–72.9) (HR 0.44 (0.20–0.95) p = 0.03). At the first relapse, median PFS for all patients was 4.2 months (95% CI 3.5–5.3). In the first relapse, mPFS was 6.7 months (95% CI 5.1–8.5) and 2.2 months (95% CI 1.9–2.9) with a combination of chemotherapy or monotherapy, respectively (p < 0.001). Conclusions: Interestingly, this vast prospective cohort of gynecological carcinosarcoma patients from the French national Rare Malignant Gynecological Tumors network (i) highlights the positive impact of adjuvant CT on survival in all localized stages (including FIGO IA uterine carcinosarcomas), (ii) confirms the importance of platinum-based combination as an option for relapse setting, and (iii) reports median PFS for various therapeutic strategies in the relapse setting.

Establishment and Validation of Prognostic Nomograms for Patients With Parotid Gland Adenocarcinoma Not Otherwise Specified: A SEER Analysis From 2004 to 2016

Background: Parotid gland adenocarcinoma not otherwise specified (PANOS) is a rare malignant tumor with limited data on its characteristics and prognosis. This research is aimed at characterizing PANOS and developing prognostic prediction models for patients with PANOS.Methods: Cases from 2004–2016 were selected from the Surveillance, Epidemiology, and End Results (SEER) Program database. Univariate and multivariate Cox regression were applied to ascertain the factors associated with survival. Competing risk analysis and Gray's tests were employed to analyze cancer-specific death. Propensity score matching (1:1) was conducted to reduce the influence of confounding variables.Results: A total of 446 patients with a median age of 66 years were selected, of which 307 were diagnosed with stage III/IV PANOS. The 5-year overall survival (OS) rate of all patients was 51.8%, and the median survival time was 66 months. Surgical treatment clearly improved survival time (p &lt; 0.001). In the subgroup analysis, radiotherapy showed survival benefits in patients with stage III/IV disease (p &lt; 0.001). Multivariate Cox regression analyses showed that age, T classification, N classification, M classification and surgery were independent prognostic indicators for OS; T classification, N classification, M classification and surgery were independent risk factors for cancer-specific survival (CSS). In addition, age was independently associated with other cause-specific death. Based on the results of multivariate analysis, two nomograms were developed and verified by the concordance index (C-index) (0.747 and 0.780 for OS and CSS) and the area under the time-dependent receiver operating characteristic (ROC) curve (0.756, 0.764, and 0.819 regarding for nomograms predicting 3-, 5-, and 10- year OS, respectively and 0.794, 0.789, and 0.806 for CSS, respectively).Conclusions: Our study clearly presents the clinicopathological features and survival analysis of patients with PANOS. In addition, our constructed nomogram prediction models may assist physicians in evaluating the individualized prognosis and deciding on treatment for patients.

The Optimization of an Anti-VEGF Therapeutic Regimen for Neovascular Glaucoma

This study investigates the safety and efficacy of conbercept injection through different routes for neovascular glaucoma (NVG) treatment, in which seventy-four patients (81 eyes) with NVG caused by ischemia retinopathy had participated. Patients were divided into three stages according to the progression of NVG and were randomly assigned to receive intracameral or intravitreal conbercept injection. After conbercept injection, patients experienced improved best-corrected visual acuity (BCVA), good intraocular pressure (IOP) control, and neovascularization of Iris (NVI) regression. In stage III, patients required trabeculectomy with mitomycin C plus pan-retinal photocoagulation (PRP) to achieve complete NVI regression. Compared to the intravitreal group, the intracameral group had significantly lower IOP in 2 days in stage III and 1 day in stages I and II after injection, complete NVI regression before PRP in stages I and II, and better NVI regression in stage III. The rates of hyphema after trabeculectomy and malfunction filtering bleb suffering needle bleb revision were lower in the intracameral group, but only the hyphema rate was significantly different. Injections through different routes are all safe. We recommend intravitreal injections for patients in stages I and II, but for stage III, intracameral injection is better, and trabeculectomy with mitomycin C should be conducted within 2 days after injection to maximally reduce the risk of perioperative hyphema.Trial Registration:ClinicalTrials.gov, identifier NCT03154892.

The Combination of Inflammation and Nutrition Factors Reinforces the Prognostic Prediction for Stage III Colorectal Cancer Patients After Curative Resection

Purpose Inflammation and nutritional status are known to be associated with the prognosis of several malignancies. Herein, we attempted to develop inflammation–nutrition scores and predict the prognosis of stage III colorectal cancer (CRC). Methods This retrospective study included 262 patients with stage III CRC who underwent curative surgery and were divided into two groups: a training set (TS) of 162 patients and a validation set (VS) of 100 patients. In the TS, clinicopathological factors were tested using a Cox regression model, and the Kansai prognostic score (KPS) was assessed by 1 point each for <3.5 g/dL albumin level, >450 monocyte counts, and <1.65 × 105 platelet counts, which were associated with disease-free survival (DFS). Using KPS, DFS and overall survival (OS) were validated in VS. Results The C-indices of KPS to predict DFS and OS in TS were 0.707 and 0.772. It was validated in VS that the C-indices of KPS to predict DFS and OS were 0.618 and 0.708, respectively. A high KPS was a significant predictor of DFS and OS. Conclusion KPS serves as a new model for the prognosis of patients with stage III CRC.
