BACKGROUND: Second-line antiretroviral therapy (ART) was introduced in Henan Province in 2009. The number of people living with human immunodeficiency virus (HIV) starting this therapy is increasing.
OBJECTIVE: This study aimed to investigate the survival and factors affecting mortality among this group.
METHODS: We conducted a retrospective cohort study of people living with HIV (PLHIV) who switched to second-line ART between May 1, 2010, and May 1, 2016, using the Kaplan-Meier method and Cox proportional hazards models.
RESULTS: We followed 3,331 PLHIV for 26,988 person-years, of whom 508 (15.3%) died. The mortality rate was 1.88/100 person-years. After adjusting for confounding factors, we found being a woman (hazard ratio (HR), 0.66; 95% confidence interval (CI) 0.55-0.79), > 50 years old (HR, 2.69; 95% CI, 2.03-3.56), single/widowed (HR, 1.26; 95% CI, 1.04-1.52), having > 6 years of education (HR, 0.78; 95% CI, 0.65-0.94), Chinese medicine (HR, 0.75; 95% CI, 0.52-0.96), liver injury (HR, 1.58; 95% CI, 1.19-2.10), and CD4+ T cell count <200 cells/μl (HR, 1.94; 95% CI, 1.47-2.55), or 200-350 cells/μl (HR, 1.37; 95% CI, 1.03-1.82) were associated with mortality risk.
CONCLUSIONS: We found lower mortality among PLHIV who switched to second-line ART than most previous studies. The limitations of a retrospective cohort may, therefore, have biased the data, and prospective studies are needed to confirm the results. Moreover, Chinese medicine combined with second-line ART shows potential as a treatment for HIV.

Purpose: To compare the prognostic value of lymph node ratio (LNR) and pN in patients with non-small cell lung cancer (NSCLC) undergoing surgery. Materials and methods: NSCLC patients were investigated between 2004 and 2015 from the Surveillance, Epidemiology, and End Results databases. The X-tile software was used to determine LNR cut-off values. Kaplan-Meier analysis was employed to assess cancer-specific survival (CSS) and overall survival (OS). Results: The identified cut-off values of LNR were 0.19 and 0.73. Median CSS for LNR1 (LNR < 0.19), LNR2 (0.19 ≤ LNR ≤ 0.73), and LNR3 (LNR > 0.73) were 71, 41, and 17 months. Both LNR2 (HR = 1.46, 95% CI: 1.36-1.57; P < 0.001) and LNR3 (HR = 2.85, 95% CI: 2.58-3.15; P < 0.001) demonstrated poorer median CSS compared to LNR1. Similarly, median OS for LNR1, LNR2, and LNR3 were 50, 35, and 16 months. LNR2 (HR = 1.36, 95% CI: 1.27-1.45; P < 0.001) and LNR3 (HR = 2.60, 95% CI: 2.37-2.85; P < 0.001) exhibited worse median OS compared to LNR1. A revised pN (r-pN) classification incorporating LNR and pN demonstrated superior penalized goodness-of-fit and discriminative ability in predicting CSS and OS compared to both LNR and pN. Conclusion: LNR outperformed pN in predicting CSS and OS in NSCLC patients undergoing surgery, potentially leading to more precise adjuvant treatment decisions.

We aim to retrospectively explore the guiding value of the Lauren classification for patients who have undergone D2 gastrectomy to choose oxaliplatin plus capecitabine (XELOX) or oxaliplatin plus S-1 (SOX) as a further systemic treatment after the operation.
We collected data of 406 patients with stage III gastric cancer(GC)after radical D2 resection and regularly received XELOX or SOX adjuvant treatment after surgery and followed them for at least five years. According to the Lauren classification, we separated patients out into intestinal type (IT) GC together with non-intestinal type(NIT) GC. According to the chemotherapy regimen, we separated patients into the SOX group together with the XELOX group.
Among non-intestinal type patients, the 3-year DFS rates in the SOX group and the XELOX group were 72.5%, respectively; 54.5% (P=0.037); The 5-year OS rates were 66.8% and 51.8% respectively (P=0.038), both of which were statistically significant.
The patients of non-intestinal type GC may benefit from the SOX regimen. Differences were counted without being statistically significant with intestinal-type GC in the SOX or XELOX groups.

OBJECTIVE: We aimed to describe the behavior among Chinese ovarian cancer patients with RAD51D germline mutations at our institution.
METHODS: Next-generation sequencing (NGS) was conducted for the entire coding regions and exon/intron boundaries of the RAD51D genes in 781 Chinese ovarian cancer patients treated at our institution from January 1, 2015 to August 1, 2021. Clinicopathological characteristics, treatment modalities, and outcomes were assessed for ovarian cancer patients with RAD51D germline mutations.
RESULTS: RAD51D germline pathogenic mutations were detected in 1.7% (13/781) of patients in this cohort. RAD51D c. 270_271dup (p. Lys91fs) mutation was the most common mutation which was found in 7 patients (7/13, 53.1%). Patients median age at diagnosis was 58 years (range: 45-69 years). 46.2% (6/13) of them were diagnosed after 60 years. Only 1 patient (1/13, 7.7%) had a family history of ovarian or breast cancer. And 1 patient (1/13, 7.7%) had a personal history of breast cancer. The FIGO 2014 distribution by stage was: stage II in 1 patient (7.7%), stage III in 9 patients (69.2%) and stage IV in 3 patient (23.1%). 92.3% (12/13) patients had high-grade serous carcinoma. 2 patients (2/13, 15.4%) had a primary peritoneal cancer. The majority of patients in the entire cohort were reported to be platinum sensitive (92.3%, 12/13) with a platinum-free interval (PFI) of > 6 months. For patients who received PARPis for 2nd line maintenance treatment (n = 5), 2 patients discontinued PARPis treatment after 33.5 and 8.1 months of duration. Other 3 patients are still on therapy with a duration of 2.4, 13.8 and 30.1 months at the date of data cutoff. 1 patient received PARPi as salvage treatment with a duration of only 1.2 months. Nine patients (9/13, 69.2%) relapsed during follow up and all of them relapsed within 2 years after diagnosis, among which 88.9% (8/9) were classified as platinum-sensitive recurrence (PSR), and only 1 patient was classified as platinum-resistant recurrence (PRR). Median PFS for the entire cohort was 17.3 months. Median PFS for the PSR subgroup was 15.9 months. 2 patients died during follow-up. The OS of these 2 patients was 17.2 and 39.6 months. The 5-year OS rate was 67.5%.
CONCLUSIONS: RAD51D germline mutations are more frequent in Chinese ovarian cancer patients than other population. Few patients have a family history of ovarian or breast cancer, and personal history of breast cancer. Most patients are diagnosed after 50 years. The sensitivity to PARP inhibitors of patients with RAD51D germline mutations need a further analysis.

BACKGROUND: Esophageal squamous cell carcinoma (ESCC) is a major subtype of esophageal cancers. The Five-year survival rate of ESCC is low and molecular targets for ESCC treatment and prognosis assessment are very limited. T cells are critical for clearance of cancer cells and blockade of co-inhibitory molecules for T cell activation has emerged as a promising therapy to treat cancer patients. However, in ESCC patients such co-inhibitory molecules regulating T cell activation is poorly documented.
OBJECTIVE: We aim to evaluate how the presence of inhibitory check-point molecules in T cells could impact survival of patients.
METHODS: We performed follow-up study of 161 patients undergoing resection of esophageal carcinoma from February 2014 to December 2015, by immunohistochemical staining of six co-inhibitory molecules for T cell activation, namely PD-1, CTLA-4, TIM-3, LAG-3, BTLA and A2AR. Expression of each of the six co-inhibitory molecules was analyzed for its correlation with patient survival by Kaplan-Meier survival analysis. We also applied Kaplan-Meier analyses to evaluate concomitant expression of co-inhibitory molecules and their correlation with patient survival.
RESULTS: We found that levels of PD-1, TIM-3 and BTLA can be used as independent prognostic factors for overall survival of patients with ESCC. More importantly, our study found that the co-expression of PD-1 and TIM-3, PD-1 and BTLA, TIM-3 and BTLA significantly reduced the survival of patients with ESCC (P<0.05).
CONCLUSIONS: Therefore, our results suggest the necessity of evaluating the tumor tissue expression of co-inhibitory molecules and targeting co-expressed molecules in immunotherapies for ESCC patients.

Nuclear receptor binding protein 1 (NRBP1) is an evolutionarily highly conserved adaptor protein with multiple domains. Recently, its role in cancers has received increasing attention. To investigate whether NRBP1 is involved in the development of bladder cancer, we used tissue microarray and analyzed the association between the expression levels of NRBP1 and clinico-pathological features of 56 patients diagnosed with bladder cancer. Subsequently, NRBP1 was silenced using siRNA in bladder cancer cell lines T24 and 5637, and cell phenotype such as proliferation and apoptosis were observed. Further, in vivo tumor formation assay was performed. The expression of apoptosis markers was detected by Western blot. A significant positive correlation between increased NRBP1 expression and tumor stage, and lymph node metastasis was observed in 56 patients. High expression of NRBP1 was associated with poor prognosis and NRBP1 knockdown significantly inhibited cell proliferation and induced intrinsic apoptosis in vitro. Moreover, we also found that NRBP1 knockdown significantly suppress tumor growth in xenograft mouse model. Taken together, these data suggest that NRBP1 plays a critical role in the development of bladder cancer and may represent a potential target for bladder cancer treatment.

Background: Pre-treatment serum lactate dehydrogenase (LDH) has emerged as prognostic factor for many cancers. In this study, we evaluated the value of LDH in predicting distant metastasis and poor survival for patients with nasopharyngeal carcinoma (NPC). Methods: Clinical data from 172 non-metastatic NPC patients were retrospectively collected and serum LDH levels were routinely measured before treatment. The independent-samples t test was used to calculate differences between serum LDH levels from the various patient groups. Receiver-operating characteristic (ROC) curve analysis was performed to select the optimal cutoff points. The Kaplan-Meier method and log-rank test were adopted to calculate and compare the distant metastasis free survival (DMFS) and overall survival (OS) rates. The Cox proportional hazards model was used to carry out univariate and multivariate analyses. Results: NPC patients progressed with distant metastasis often have higher pre-treatment serum LDH levels than those did not develop distant metastasis (mean LDH level was 237.1U/L and 108.8U/L, respectively, p=0.001). Elevated LDH level was identified as an independent prognostic factor for poor DMFS (hazard ratio (HR), 8.31; 95% confidence interval (CI), 2.44-28.32; p=0.001) and OS (HR, 4.45; 95% CI, 1.77-11.21; p=0.002). Moreover, subgroup analyses revealed significant associations between serum LDH level and worse survival in advanced stage patients. Conclusions: Pre-treatment serum LDH level can predict distant metastasis and associate with the poor survival in patients with NPC.

BACKGROUND: Esthesioneuroblastoma (ENB) is an uncommon neoplasm arising from the olfactory mucosa. The optimal treatment regimen for ENB remains unclear. This study aims to evaluate its clinical features, long-term outcomes and explore optimal treatment patterns. METHODS: Clinical data of consecutive 44 ENB patients were reviewed retrospectively. The correlation between clinical features and treatment approaches were analyzed, with several prognostic factors explored meanwhile. RESULTS: The age of onset of ENB showed a bimodal distribution, with peaks at 10~20 and 50~60 years. The median follow-up time was 84 months (range, 27~198 months).The 5-year overall and progression free survival rates were 42.7% and 39.1%, respectively, with 10-year rates of 28.9% and 21.7% respectively. Overall, 19 patients developed recurrent disease. Patients undergoing surgery combined with adjuvant radiotherapy had significantly higher 5-year overall survival (67.5% vs. 33.3%, P=0.043) and progress-free survival (60.0%vs. 18.7%, P=0.008) than those receiving other treatment approaches. No-Skin-involved ENB was associated with markedly better 5-year overall survival (45.5%vs.0 %, P=0.038) and progress-free survival (31.3% vs. 0 %, P=0.001) compared with skin-involved tumor. CONCLUSIONS: ENB is a rarely malignant tumor with high probability of locoregional recurrence and poor survival. Surgical resection followed by radiotherapy has been shown to achieve optimal local control and overall survival.

Objective: To analyze the prognostic value of pre-treatment serum lactate dehydrogenase (SLDH) level in patients with nasopharyngeal carcinoma (NPC) receiving intensity-modulated radiotherapy (IMRT) with or without chemotherapy. Methods: From January 2010 to March 2013, 427 eligible patients were reviewed. Pre-treatment SLDH level was measured within 2 weeks prior to treatment. Receiver operating characteristic (ROC) curve analysis was performed to select the optimal cutoff point. The impact of pre-treatment SLDH on overall survival (OS), progression-free survival (PFS) and distant metastasis-free survival (DMFS) were analyzed using Kaplan-Meier method and Cox proportional hazards model. Further propensity score matching was carried out to adjust bias. Results: The optimal cutoff point of 168.5 IU/L was selected based on ROC curve analysis. Multivariate analysis showed that high pre-treatment SLDH level was an independent prognostic factor for OS (P=0.001), PFS (P=0.004) and DMFS (P=0.001). After propensity score matching was performed, it remained to be significantly associated with poor OS (P=0.009), PFS (P=0.015) and DMFS (P=0.008) in the adjusted model. Conclusion: High pre-treatment SLDH level predicts poor survival in patients with NPC treated with IMRT-based therapy. As a routinely performed biomarker, pre-treatment SLDH can be utilized in combination with current Tumor-Node-Metastasis staging to predict survival and to plan a personalized treatment in these patients.
