Abstract
BACKGROUND Modern treatment guidelines for women with advanced cervical cancer recommend staging using 2-deoxy-2-[18F]fluoro-D-glucose positron emission computed tomography ([18F]FDG-PET/CT). However, the risk of false-positive nodes and therapy-related adverse events requires caution in treatment planning. Using data from the Netherlands Cancer Registry (NCR), we estimated the impact of [18F]FDG-PET/CT on treatment management in women with locally advanced cervical cancer, i.e., on nodal boosting, field extension, and/or debulking in cases of suspected lymph nodes. METHODS Women diagnosed between 2009 and 2017, who received chemoradiotherapy for International Federation of Gynaecology and Obstetrics (2009) stage IB2, IIA2-IVB cervical cancer with an [18F]FDG-positive node, were retrospectively selected from the NCR database. Patients with pathological nodal examination before treatment were excluded. The frequency of nodal boosting, extended-field radiotherapy, and debulking procedures applied to patients with [18F]FDG-positive lymph nodes was evaluated. RESULTS Among the 434 eligible patients with [18F]FDG-positive nodes, 380 (88%) received interventions targeting these lymph nodes: 84% of these 380 patients received nodal boosting, 78% extended-field radiotherapy, and 12% debulking surgery. [18F]FDG-positive nodes in patients receiving these treatments were more likely to be classified as suspicious than inconclusive (p = 0.009), located in the para-aortic region (p < 0.001), and larger (p < 0.001) than in patients who did not receive these treatments. CONCLUSION While existing guidelines advocate [18F]FDG-PET/CT-guided treatment planning for the management of advanced cervical cancer, this study highlights that not all cases of [18F]FDG-positive nodes received an intervention, possibly due to the risk of false-positive results. Improvement of nodal staging may reduce suboptimal treatment planning.

Abstract
Background The outcomes of locally advanced non-small cell lung cancer (LA-NSCLC) are unfavorable mainly due to a high risk of cancer recurrence. Only around 5% of patients can benefit from perioperative chemotherapy which is the current standard treatment. Recently, promising results with neoadjuvant targeted and immune-therapy therapy have been seen. However, most clinical trials are looking for patients eligible for certain drugs, instead of seeking suitable treatments for certain patients. Therefore, it is necessary to look for more efficient perioperative therapies to increase resectability, reduce recurrence and improve prognosis. Methods/Design The study is an open-label, prospective, phase II, umbrella trial, enrolling patients diagnosed with treatment-naïve potentially resectable Stage II-IIIB NSCLC. Next-generation sequencing (NGS) using a 68-gene panel is performed for biopsies of tumor tissues from eligible patients. Enrolled patients are then stratified into six independent cohorts based on the status of gene mutations and PD-L1 status in tumor tissues, that is, ①EGFR 19del group, ②EGFR 21 L858R group, ③EGFR rare mutation group, ④Other driver mutation group, ⑤Drive mutation-negative group with PD-L1≥1%, ⑥Drive mutation-negative group with PD-L1<1%. A Simon's two-stage design is performed in each cohort independently and patients receive corresponding standard therapies accordingly. We aim to enroll 26 patients in each cohort and totally 156 patients will be enrolled. The primary endpoint is objective response rate (ORR). Secondary endpoints include oncological prognosis and perioperative outcomes. Exploratory endpoint is to investigate patient-specific minimal residual disease (MRD) in predicting treatment efficacy and oncological prognosis. Discussions This is the first umbrella trial focusing on the safety and efficacy of precise neoadjuvant therapy for patients diagnosed with potentially resectable LA-NSCLC based on NGS results. The results of this trial would help improve overall treatment results in LA-NSCLC patients. Trial registration Chinese Clinical Trial Registry. Trial registration number: ChiCTR2100053021. Advantages and limitations of this study There is no neoadjuvant umbrella trial focusing on LA-NSCLCs. This is the first neoadjuvant umbrella trial, using a precise individualized approach and seeking suitable drugs for LA-NSCLC patients, with the aim to improve overall treatment outcomes.

Abstract
Objective: This study aimed to evaluate neoadjuvant chemotherapy (NACT) for locally advanced stage cervical carcinoma. Materials and Methods: Data of 43 patients with locally advanced cervical carcinoma who had NACT were reviewed. NACT protocols implemented included cisplatin/5-fluorauracil, cisplatin/UFT, and carboplatin/paclitaxel. After NACT, the patients were re-examined, and patients who had a tumor size ≤40 mm underwent Piver-Rutledge type III radical hysterectomy, while other patients received radiotherapy. Following NACT, clinical responses were assessed according to the criteria of the World Health Organization. Results: The mean age of the patients was 49.4 years, and the median follow-up duration was 48 (range, 5-228) months. The median tumor sizes were 50 and 30 mm before and after NACT, respectively. Complete clinical response was observed in 4 (9.3%) patients, partial clinical response in 8 (18.6%), and pathologic complete response in 3 (6.9%). Stable disease was noted in 30 (69.9%) patients and progression in 1 (2.3%) patient. After NACT, 31 patients have undergone radical surgical procedures. The 5-year disease-free survival rate was 72%, and the 5-year disease-specific survival rate was 91%. Age, International Federation of Gynaecology and Obstetrics 2009 stage, histopathologic type, NACT protocol, rate of decrease in tumor size after NACT, clinical response, number of courses, tumor size before NACT, tumor size after NACT, and lymph node metastasis were not associated with disease-free survival. Conclusion: Following NACT, a significant reduction in tumor dimension was observed, and the probability of radical surgery is increased. However, clinical response was not predictive of survival.

Abstract
Objective: To evaluated the oncologic outcomes associated with platinum-based adjuvant chemotherapy following concurrent chemoradiotherapy (CCRT) in the management of patients with locally advanced cervical cancer (LACC). Methods: A total of 695 patients with FIGO stage IB2, IIA2, IIB-IVA LACC treated at 6 medical facilities were enrolled and divided into 2 groups: 478 were assigned to CCRT alone (CCRT group) and 217 to adjuvant chemotherapy after CCRT (CCRT-ACT group). The treatment outcomes were retrospectively compared and reported after the propensity score matching (PSM) analysis. Results: With a median follow-up of 56.4 months, no statistically significant differences were found in overall survival (OS), disease-free survival (DFS), progression-free survival (PFS) and distance metastasis-free survival (DMFS) between 2 groups. In CCRT-ACT group, patients with lymph nodes involvement or squamous cell carcinoma (SCC) had significantly longer DMFS, but no significant benefit in survival outcomes were observed with more than 2 cycles of adjuvant chemotherapy. Moreover, patients with a high level of CA125 (>20.5U/mL) or SCC-Ag (>22.8μg/L) had a relatively better DFS or PFS, and grade 3-4 acute hematological toxicity, late urinary and lower gastrointestinal complications and diarrhea symptom were more frequent in CCRT-ACT group. Conclusions: Adjuvant chemotherapy after CCRT has a potential role in further improving disease control for LACC patients with lymph nodal-metastasis or SCC with a high level of CA125 or SCC-Ag. Due to increased treatment-related complications and diarrhea symptom affecting the quality of life, post-CCRT adjuvant chemotherapy with excessive cycles was not be considered as the most appropriate choice in general.

Abstract
Objectives To develop nomograms to assess prognostic factors for 5-year overall survival (OS) and 5-year progression-free survival (PFS) in locally advanced cervical squamous cell carcinoma (LACSC). Methods Overall, 618 patients with LACSC were included in this retrospective analysis. Nomograms for 5-year OS and PFS were developed based on Cox proportional hazards regression models. Concordance index (C-index) and calibration curves were used to define the predictive and discriminatory capacity of the nomogram. A comparison between the nomogram and the International Federation of Gynecology and Obstetrics (FIGO) staging system was conducted using time-dependent receiver operating characteristic (tROC) and area under the curve (tAUC). Results Multivariate analysis identified several prognostic factors for OS including squamous cell carcinoma antigen (SCC-Ag), body mass index (BMI), tumor size, pelvic wall involvement, and para-aortic lymph node metastasis (PALNM). Prognostic factors for PFS included BMI, hemoglobin (HGB), tumor size, pelvic wall involvement, pelvic lymph node metastasis (PLNM) and PALNM. Following bootstrap correction, the C-index of OS and PFS was 0.713 and 0.686, respectively. These nomograms showed superior performance compared with the FIGO 2009 and 2018 staging schema. Conclusions Nomograms were developed to identify prognostic factors for 5-year OS and PFS in patients with LACSC. These nomograms showed good prognostication and are more comprehensive in predicting survival outcomes than existing staging criteria.

Abstract
Aim: To determine whether pretreatment of neutrophil-to-lymphocyte ratio (NLR) or platelet-to-lymphocyte ratio (PLR) has a prognostic value in patients with inoperable locally advanced non-small-cell lung cancer. Materials & methods: A total of 167 patients between 2013 and 2016 were analyzed retrospectively. Results: Appropriate cut-off values for initial NLR (3.06) and PLR (168.03) were determined by receiver operating characteristic curves. High NLR (p < 0.001 and p < 0.001) was related to poor overall survival (OS) and progression-free survival (PFS) via univariate analysis. Multivariable analysis showed that NLR can independently influence OS (hazard ratio: 1.570; p = 0.012) and PFS (hazard ratio: 1.471; p = 0.023). PLR did not correlate with OS or PFS. Conclusion: Pretreatment of NLR could independently predict the prognosis of inoperable locally advanced non-small-cell lung cancer patients, while pretreatment of PLR does not have prognostic value.

Abstract
Standard therapy for nasopharyngeal cancer (NPC) is concurrent chemoradiation. Nevertheless, therapeutic outcomes are often unsatisfactory particularly for locally advanced stage. To enhance the therapeutic outcome, we may consider using altered fraction radiotherapy. Altered fraction radiotherapy is divided into two large groups for the therapy of NPC: hyperfraction radiotherapy and accelerated fraction radiotherapy. One of the accelerated fraction regimens suitable for NPC therapy is an accelerated regimen of six radiotherapy fractions weekly. This regimen is considered safe whether using conventional 2D planning technique or advance technique. Response to radiotherapy is better owing to the decrease in overall treatment time (OTT). Furthermore, acute or late side effects for this therapy are not very different to those of standard therapy. The conclusion is that we recommend the use of an accelerated regimen of six radiotherapy fractions weekly for locally advanced stage NPC with contraindication to concurrent chemoradiation, due to the high degree of clinical outcome as well as better tolerated side effect for NPC patients, particularly for those with locally advanced stage NPC.

Abstract
Over the last decade, several steps forward in the treatment of patients with stage IV non-small cell lung cancer (NCSLC) were made. Examples are the use of pemetrexed, pemetrexed maintenance therapy, or bevacizumab for patients with nonsquamous NSCLC. A big leap forward was the use of tyrosine kinase inhibitors in patients selected on the basis of an activating oncogene, such as epidermal growth factor receptor (EGFR) activating mutations or anaplastic lymphoma kinase (ALK) translocations. However, all of these achievements could not be translated into survival benefits when studied in randomized controlled trials in patients with nonmetastatic NSCLC. Aside from chemotherapy and targeted therapy, immunotherapy has become the third pillar in the treatment armamentarium of advanced NSCLC. Antigen-specific immunotherapy (cancer vaccination) has been disappointing in large phase III clinical trials in stages I–III NSCLC. Based on the recent breakthroughs with immune checkpoint inhibitor immunotherapy in metastatic NSCLC, much hope currently rests on the use of this approach in patients with stage I–III NSCLC as well. Here we give a brief overview of how most new therapeutic approaches for advanced NSCLC failed in other stages, and then elaborate on the role of immunotherapy in patients with stage I–III NSCLC.

Abstract
Objective Formerly, locally advanced prostate cancer exhibited poorly prognosis. In the late 1990s, new surgical and radiation technologies were introduced in combination with androgen deprivation. To evaluate respective strategies, outcomes were examined. Patients and methods Between 2001 and 2010, 224 patients with T3N0M0 (10.9% of all prostate cancer cases) were treated with prostatectomy, external beam radiation therapy with/without androgen deprivation or hormone alone. Complete records were obtained by the end of 2015. Results Operation group first started without adjuvant treatment and prostate-specific antigen (PSA) relapse occurred in 39% of cases. Radiation therapy group was alternatively divided into two subgroups, that received either monotherapy or combination with androgen deprivation, and PSA relapse rates were 65 and 16%, respectively. High rates of PSA relapse in both the operation and radiation therapy groups were observed in patients without adjuvant therapy, but after relapse androgen deprivation proceeded favorable outcomes. In the radiation subgroups, PSA relapse rates were different, but both subsequent survival rates were the same. This may be due to the effect of androgen deprivation after relapse, indicating effect of delayed therapy. PSA relapse rate in the hormone therapy group was 25% and after relapse, patients applied to treatment with other hormonal and anticancer drugs. Overall survival rates were 91, 88 and 67% in the operation, radiation therapy and hormone therapy groups, respectively. Conclusion Aggressive treatment with short-term androgen deprivation for locally advanced prostate cancer could be beneficial and not harmful when suitable candidates are selected. Delayed androgen deprivation was effective for no adjuvant patients after PSA relapse.

Abstract
Nonadvanced non-small-cell lung cancer (NSCLC) has a poor long-term survival from surgery or definitive radiation that is minimally improved with induction/adjuvant conventional chemotherapy. EGFR-tyrosine kinase inhibitors (TKIs), which provide a significant benefit for molecularly selected EGFR-mutant patients with advanced NSCLC, have been infrequently explored in nonadvanced NSCLC to date. Current published studies reported no significant benefit from adding EGFR-TKI to the induction/adjuvant setting. However, many of them present eventual biases such as unpowered statistics, lack of molecular selection, recruitment of low-risk NSCLC, low sample size or unsuitable control arms. Results, strengths and deficiencies of completed and ongoing trials were fully discussed. Similarly, the selection of patients and control arms, the duration and risks of EGFR-TKI therapies in early-stage NSCLC, the evaluation of response and the diagnosis of EGFR status were considered and analyzed.

Abstract
Introduction Paradoxically, a breast cancer risk reduction with conjugated equine estrogens (CEE) and a risk elevation with CEE plus medroxyprogesterone acetate (CEE + MPA) were observed in the Women’s Health Initiative (WHI) randomized controlled trials. The effects of hormone therapy on serum sex hormone levels, and on the association between baseline sex hormones and disease risk, may help explain these divergent breast cancer findings. Methods Serum sex hormone concentrations were measured for 348 breast cancer cases in the CEE + MPA trial and for 235 cases in the CEE trial along with corresponding pair-matched controls, nested within the WHI trials of healthy postmenopausal women. Association and mediation analyses, to examine the extent to which sex hormone levels and changes can explain the breast cancer findings, were conducted using logistic regression. Results Following CEE treatment, breast cancer risk was associated with higher concentrations of baseline serum estrogens, and with lower concentrations of sex hormone binding globulin. However, following CEE + MPA, there was no association of breast cancer risk with baseline sex hormone levels. The sex hormone changes from baseline to year 1 provided an explanation for much of the reduced breast cancer risk with CEE. Specifically, the treatment odds ratio (95% confidence interval) increased from 0.71 (0.43, 1.15) to 0.92 (0.41, 2.09) when the year 1 measures were included in the logistic regression analysis. In comparison, the CEE + MPA odds ratio was essentially unchanged when these year 1 measures were included. Conclusions Breast cancer risk remains low following CEE use among women having favorable baseline sex hormone profiles, but CEE + MPA evidently produces a breast cancer risk for all women similar to that for women having an unfavorable baseline sex hormone profile. These patterns could reflect breast ductal epithelial cell stimulation by CEE + MPA that is substantially avoided with CEE, in conjunction with relatively more favorable effects of either regimen following a sustained period of estrogen deprivation. These findings may have implications for other hormone therapy formulations and routes of delivery. Trial registration clinicaltrials.gov identifier:

Abstract
OBJECTIVE This study sought to investigate the role of the long noncoding RNA MALAT1 in the prognosis of stage II/III colorectal cancer (CRC) patients. METHODS The expression of MALAT1 was evaluated in cancer tissues from 146 stage II/III CRC patients undergoing radical resection and 23 paired normal colonic mucosa samples using quantitative real-time reverse transcriptase PCR. Differences in the expression of MALAT1 between 23 CRC and paired normal colonic mucosa samples were analysed with the Wilcoxon test. Relationships between the expression level of MALAT1, patient clinicopathological parameters and disease-free survival (DFS) and overall survival (OS) were analysed using the univariate Kaplan-Meier method and the multivariate COX regression model. RESULTS The MALAT1 levels in cancerous tissues were 2.26 times higher than those measured in noncancerous tissues, and this difference was statistically significant (P = 0.0004). Based on their expression level of MALAT1, the patients were divided into a high MALAT1 expression group (n = 73) and a low expression group (n = 73). Patients with tumours harbouring higher expression of MALAT1 showed a significantly worse prognosis with a hazard ratio (HR) of 2.863 (95% CI, 1.659 to 4.943; P < 0.001) for DFS and 3.968 (95% CI, 1.665 to 9.456; P = 0.002) for OS. Furthermore, patients with perineural invasion demonstrated significantly worse DFS (HR = 3.459, 95% CI 2.008 to 5.957; P < 0.001) and OS (HR = 3.750, 95% CI 1.743 to 8.069; P = 0.001) than those without perineural invasion. Multivariate analyses indicated that MALAT1 expression and perineural invasion were two independent prognostic risk factors for patients with CRC. CONCLUSION The expression of MALAT1 is upregulated in CRC tissues, and a higher expression level of MALAT1 might serve as a negative prognostic marker in stage II/III CRC patients.
