ABSTRACT
BACKGROUND: Patient-reported outcomes (PROs) are a better tool for evaluating the experiences of patients who have symptomatic, treatment-associated adverse events (AEs) compared with clinician-rated AEs. The authors present PROs assessing health-related quality of life (HRQoL) and treatment-related neurotoxicity for adjuvant capecitabine versus platinum on the Eastern Cooperative Oncology Group-American College of Radiology Imaging Network (ECOG-ACRIN) EA1131 trial (ClinicalTrials.gov identifier NCT02445391). METHODS: Participants completed the National Comprehensive Cancer Network Functional Assessment of Cancer Therapy-Breast Cancer Symptom Index (NFBSI-16) and the Functional Assessment of Cancer Therapy-Gynecologic Oncology Group neurotoxicity subscale (platinum arm only) at baseline, cycle 3 day 1 (C3D1), 6 months, and 15 months. Because of early termination, power was insufficient to test the hypothesis that HRQoL, as assessed by the NFBSI-16 treatment side-effect (TSE) subscale, would be better at 6 and 15 months in the capecitabine arm; all analyses were exploratory. Means were compared by using t-tests or the Wilcoxon rank-sum test, and proportions were compared by using the χ2 test. RESULTS: Two hundred ninety-six of 330 eligible patients provided PROs. The mean NFBSI-16 TSE subscale score was lower for the platinum arm at baseline (p = .02; absolute difference, 0.6 points) and for the capecitabine arm at C3D1 (p = .04; absolute difference, 0.5 points), but it did not differ at other times. The mean change in TSE subscale scores differed between the arms from baseline to C3D1 (platinum arm, 0.15; capecitabine arm, -0.72; p = .03), but not from baseline to later time points. The mean decline in Functional Assessment of Cancer Therapy-Gynecologic Oncology Group neurotoxicity subscale scores exceeded the minimal meaningful change (1.38 points) from baseline to each subsequent time point (all p < .05). CONCLUSIONS: Despite the similar frequency of clinician-rated AEs, PROs identified greater on-treatment symptom burden with capecitabine and complemented clinician-rated AEs by characterizing patients' experiences during chemotherapy.

BACKGROUND: We assessed the accuracy of four estimated glomerular filtration rate (eGFR) methods: MDRD, Cockcroft-Gault, CKD-EPI, and Wright. METHOD: The four methods were compared to measure GFR (mGFR) in patients with urothelial urinary tract cancer (T2-T4bNxMx) receiving platinum-based chemotherapy at Rigshospitalet, Copenhagen, from January 2019 to December 2021. Using standardized assays, creatinine values were measured, and mGFR was determined using Technetium-99 m diethylenetriaminepentaacetic acid (Tc-99 m-DTPA) or Cr-51-ethylenediaminetetraacetic acid (Cr-51-EDTA) plasma clearance. Patients (n = 146) with both mGFR and corresponding creatinine values available were included (n = 345 measurements). RESULTS: The CKD-EPI method consistently demonstrated superior accuracy, with the lowest Total Deviation Index of 21.8% at baseline and 22.9% for all measurements compared to Wright (23.4% /24.1%), MDRD (26.2%/25.5%), and Cockcroft-Gault (25.x%/25.1%). Bland Altman Limits of agreement (LOA) ranged from - 32 ml/min (Cockcroft-Gault) to + 33 ml/min (MDRD), with CKD-EPI showing the narrowest LOA (- 27 ml/min to + 24 ml/min and lowest bias (0.3 ml/min). Establishing an eGFR threshold at 85 ml/min-considering both the lower limit of agreement (LOA) and the minimum cisplatin limit at 60 ml/min-allows for the safe omission of mGFR in 30% of patients in this cohort. CONCLUSION: CKD-EPI equation emerged as the most suitable for estimating kidney function in this patient group although not meeting benchmark criteria. We recommend its use for initial assessment and ongoing monitoring, and suggest mGFR for patients with a CKD-EPI estimated GFR below 85 ml/min. This approach could reduce costs and decrease laboratory time for 30% of our UC patients.

BACKGROUND: About 30% of pulmonary stage IV adenocarcinomas die within 3 months of diagnosis. Western medical treatments with Platinum-Based Chemotherapy=PBC and tyrosine-kinase inhibitors Targeted Therapy=TT can improve prognosis. In China, Traditional Chinese Medicine herbal treatments (TCM) are often used in addition to PBC and TT. A considerable number of patients refuse Western medical treatments and use TCM alone. However, the survival impact of the latter is unknown. HYPOTHESES TESTED: Treatment with TCM alone is prognostically superior to PBC alone. Addition of PBC or TT or both TT to TCM improves survival. METHODS: In this prospective observational, non-interventional study of 1017 consecutive first-onset stage IV NSCLC patients with up to 10 years follow-up, 261 who Died of Disease (DOD) within 3 months were omitted, as they never got the optimal Western medical therapies. All 218 non-adenocarcinomas were also omitted, leaving 538 stage IV adenocarcinomas treated by TCM alone (n = 29), PBC alone (N = 19) and TCM and other Western medical combinations (299 TCM and PBC, 50 TCM and TT, 141 TCM and PBC and TT) with 3 - 120 months follow-up. Survivals were compared using Alive with Disease (AWD) and DOD as endpoints. RESULTS: The patients treated only with TCM had 7 months better median survival than those that received PBC alone (17 and 10 months). The patients that received TCM and PBC had a better median survival (24 months) than TCM alone and much better than PBC alone. None of the patients that received TCM alone survived > 54 months, whereas 18% of TCM and PBC patients survived much longer. Over the observation period of 3 - 120 months, survivals of TCM and TT, TCM and PBC and TT, and TCM and PBC were not different and therefore grouped as TCM and Western medicines. Median survival times of PBC alone and TCM alone were lower than that of TCM and Western medical treatments (p < 0.0001, 10, 17 and 27 months). CONCLUSIONS: Pulmonary stage IV adenocarcinoma patients with at least 3 months survival, treated with TCM alone have a significantly better survival than those treated with PBC alone. Adding Western PBC, TT or both to TCM further improves prognosis.

BACKGROUND: Pembrolizumab is approved for the neoadjuvant/adjuvant treatment of early triple-negative breast cancer (TNBC) patients in combination with chemotherapy. The Keynote-522 trial used platinum chemotherapy. As neoadjuvant nab-paclitaxel (nP) is also highly effective in triple-negative breast cancer patients, this study investigates the response to nP-containing neoadjuvant chemotherapy in combination with pembrolizumab. PATIENTS AND METHODS: NeoImmunoboost (AGO-B-041/NCT03289819) is a multicenter, prospective single-arm phase II trial. Patients were treated with 12 weekly cycles of nP followed by four three-weekly cycles of epirubicin/cyclophosphamide. Pembrolizumab was given three-weekly in combination with these chemotherapies. The study was planned for 50 patients. After 25 patients, the study was amended to include a pre-chemotherapy single application of pembrolizumab. The primary aim was pathological complete response (pCR), and the secondary aims were safety and quality of life. RESULTS: Of 50 included patients, 33 (66.0%; 95%confidence interval: 51.2%-78.8%) had a (ypT0/is ypN0) pCR. The pCR rate in the per-protocol population (n = 39) was 71.8% (95%confidence interval: 55.1%-85.0%). The most common adverse events of any grade were fatigue (58.5%), peripheral sensory neuropathy (54.7%) and neutropenia (52.8%). The pCR rate in the cohort of 27 patients with a pre-chemotherapy pembrolizumab dose was 59.3%, and 73.9% in the 23 patients without pre-chemotherapy dose. CONCLUSIONS: pCR rates after NACT with nP and anthracycline combined with pembrolizumab are encouraging. With acceptable side-effect profiles, this treatment might be a reasonable alternative to platinum-containing chemotherapy in cases of contraindications. However, without data from randomised trials and long-term follow up, platinum/anthracycline/taxane-based chemotherapy remains the standard combination chemotherapy for pembrolizumab.

BACKGROUND: Data on platinum sensitivity of low-grade serous ovarian carcinoma (LGSOC) in the upfront setting is lacking, and there is limited and contradictory information on chemotherapy responses in recurrent disease. METHODS: Patients with LGSOC seen at a comprehensive cancer center from January 1, 1998 to September 30, 2021 were identified from institutional databases. Response to neoadjuvant chemotherapy (NACT) or adjuvant platinum-based chemotherapy and to second- to fifth-line regimens was retrospectively characterized by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Wilcoxon rank-sum and two-tailed Fisher exact tests were employed. RESULTS: Of 50 patients, 12 received platinum doublets for suboptimal residual disease and 11 as NACT. Of 12 patients with suboptimal residual disease, seven (58%) achieved objective responses (five partial responses [PRs] and two complete responses); of the 11 patients who underwent NACT, one (9%) achieved a PR (p = .027). The 15 remaining patients had stable disease on first-line platinum chemotherapy. Of 44 patients who recurred, 20 had RECIST-evaluable responses to second-line and 27 to third-line chemotherapy. Objective response rates to platinum-based chemotherapy were 22% (two of nine) in the second line and 10% (one of 10) in the third. In second and third lines, highest response rates were observed with nonplatinum chemotherapy with bevacizumab, at 100% (two of two) and 30% (three of 10), respectively. CONCLUSIONS: Primary platinum-based chemotherapy has moderate activity in LGSOC and minimal activity in the recurrent setting, suggesting standard definitions of platinum sensitivity may not apply in LGSOC. In the second and third lines, nonplatinum chemotherapy/bevacizumab elicited the highest response rates.

BACKGROUND: The original meta-analysis of hyperthermic intraperitoneal chemotherapy (HIPEC) is already outdated, owing to the latest trial results. This study aimed to clarify the efficacy and adverse events of cytoreductive surgery with HIPEC compared to conventional therapy for advanced and platinum-sensitive recurrent epithelial ovarian cancer (OC). METHODS: In this meta-analysis, phase II/III controlled trials regarding 'HIPEC' and 'ovarian cancer' were searched for in electronic databases from inception to March 2022. RESULTS: Twenty-one studies were included in the quantitative synthesis. The pooled hazard ratio [HR] in the HIPEC group for progression-free survival (PFS) (HR = 0.61, 95% confidence interval [CI]: 0.45-0.83, p = .002) and overall survival (OS) (HR = 0.65, 95% CI: 0.51-0.82, p < .001) were improved in the HIPEC group compared with the non-HIPEC group. For primary advanced disease, OS and PFS were significantly increased in patients receiving interval debulking surgery + HIPEC, whereas PFS was not significantly different between primary debulking surgery (PDS) + HIPEC and PDS alone. For platinum-sensitive recurrent disease, no correlation was observed for PFS and OS between the HIPEC and non-HIPEC groups (p < .05). The incidence of procedure-related complications was higher in the HIPEC group than in the non-HIPEC group (odds ratio = 1.93, 95% CI: 1.24-3.01, p < .01). The morbidity of leukopenia, neutropenia, nausea, hypoalbuminemia, and grades III-IV electrolyte disturbance was higher in the HIPEC group than in the non-HIPEC group. However, HIPEC administration reduced the risk of intra-abdominal bleeding and constipation. CONCLUSION: HIPEC-based regimens improved the clinical prognosis for primary advanced OC, whereas no significant value was elicited for recurrent OC.

Aim: This systematic literature review and network meta-analysis evaluated the efficacy and safety of sintilimab + pemetrexed + platinum versus US FDA-approved/National Comprehensive Cancer Network-recommended immune checkpoint inhibitor (ICI) combination therapies for untreated advanced/metastatic non-squamous non-small-cell lung cancer without EGFR/ALK aberrations. Methods: Bayesian network meta-analysis was the base-case analysis and included assessment of fixed and random effects, and independent and simultaneous models, adjusting for baseline risk (placebo response). Chemotherapy was the common comparator. Results: Sintilimab + pemetrexed + platinum was associated with significantly longer progression-free survival than atezolizumab + platinum + nab-paclitaxel (hazard ratio [HR]: 0.57; 95% credible interval [CrI]: 0.40-0.82) and nivolumab + ipilimumab + pemetrexed + platinum (HR: 0.66; 95% CrI: 0.48-0.92). Sintilimab + pemetrexed + platinum and pembrolizumab + pemetrexed + platinum showed comparable progression-free survival (HR: 0.96; 95% CrI: 0.71-1.30). There was no significant difference in overall survival (HR range: 0.61-0.81) or overall response rates (odds ratio [OR] range: 0.29-0.75) between sintilimab + pemetrexed + platinum and the other ICI combinations. The incidence of high-grade adverse events was higher with sintilimab + pemetrexed + platinum than with nivolumab + ipilimumab (OR: 0.46; 95% CrI: 0.33-0.64) or without chemotherapy (OR: 0.25; 95% CrI: 0.19-0.34), with no significant difference between sintilimab + pemetrexed + platinum and the other ICI combinations. Conclusion: Sintilimab + pemetrexed + platinum showed comparable efficacy and safety versus US standard-of-care first-line ICI combinations for advanced/metastatic non-squamous non-small-cell lung cancer.
Sintilimab is an immunotherapy drug that was successfully developed and tested in China to treat a kind of lung cancer that has spread, called advanced non-squamous non-small-cell lung cancer (NSCLC). The ORIENT-11 clinical study showed that adding sintilimab to two types of chemotherapy (pemetrexed and platinum) as the first treatment for people in China with advanced non-squamous NSCLC was safe and effective in reducing the risk of cancer spreading, growing or getting worse, compared with chemotherapy alone. Our study combined and analyzed the results from 11 clinical studies to look at how well sintilimab with chemotherapy may work compared with immunotherapy drugs approved in the USA. The results showed that sintilimab with chemotherapy is as effective and safe as immunotherapy drugs approved in the USA to treat people with advanced non-squamous NSCLC. These results may help doctors and payers when deciding how to treat people with this disease.

BACKGROUND: In JAVELIN Bladder 100, avelumab first-line maintenance plus best supportive care (BSC) significantly prolonged overall survival (OS; primary endpoint) versus BSC alone in patients with advanced urothelial carcinoma (aUC) without disease progression with first-line platinum-containing chemotherapy. OBJECTIVE: To evaluate patient-reported outcomes (PROs) with avelumab plus BSC versus BSC alone. DESIGN, SETTING, AND PARTICIPANTS: A randomized phase 3 trial (NCT02603432) was conducted in 700 patients with locally advanced or metastatic urothelial carcinoma that had not progressed with first-line gemcitabine plus cisplatin or carboplatin. PROs were a secondary endpoint. INTERVENTION: Avelumab plus BSC (n = 350) or BSC alone (n = 350). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: National Comprehensive Cancer Network/Functional Assessment of Cancer Therapy Bladder Symptom Index-18 (FBlSI-18) and EuroQol five-level EQ-5D (EQ-5D-5L) assessments were analyzed using descriptive statistics and mixed-effect models. Time to deterioration (TTD; prespecified definition: a ≥3-point decrease from baseline in the FBlSI-18 disease-related symptoms-physical subscale for two consecutive assessments) was evaluated via Kaplan-Meier analyses. RESULTS AND LIMITATIONS: Completion rates for scheduled on-treatment PRO assessments were >90% (overall and average per assessment). Results from descriptive analyses and mixed-effect or repeated-measures models of FBlSI-18 and EQ-5D-5L were similar between arms. TTD was also similar, both in the prespecified analysis (hazard ratio 1.26 [95% confidence interval: 0.90, 1.77]) and in the post hoc analyses including off-treatment assessments and different event definitions. Limitations included the open-label design and limited numbers of evaluable patients at later time points. CONCLUSIONS: Addition of avelumab first-line maintenance to BSC in patients with aUC that had not progressed with first-line platinum-containing chemotherapy prolonged OS, with a relatively minimal effect on quality of life. PATIENT SUMMARY: In this trial of people with advanced urothelial carcinoma who had benefited from first-line chemotherapy (ie, had stable disease or reduced tumor size), treatment with avelumab maintenance plus best supportive care (BSC) versus BSC alone improved survival significantly, without compromising quality of life, as reported by the patients themselves.

BACKGROUND: Neoadjuvant chemotherapy (NAC) for locally advanced gastric and gastroesophageal junction adenocarcinoma (LAGC) has been recommended in several guidelines. However, there is no global consensus about the optimum of NAC regimens. We aimed to determine the optimal NAC regimen for LAGC. METHODS: A systematic review and Bayesian network meta-analysis was performed. The literature search was conducted from inception to June 2022. The odds ratio (OR) value and 95% confidence interval (95% CI) were used for assessment of R0 resection rate and pathological complete response rate (pCR) as primary outcomes. The hazard ratio (HR) value and 95% CI were interpreted for the assessment of overall survival (OS) and disease-free survival (DFS) as second outcomes. The risk ratio (RR) value and 95% CI were used for safety assessment. RESULTS: Twelve randomized controlled trials were identified with 3846 eligible participants. The network plots for R0 resectability, OS, and DFS constituted closed loops. The regimens of TPF (taxane and platinum plus fluoropyrimidine), ECF (epirubicin and cisplatin plus fluorouracil), and PF (platinum plus fluoropyrimidine) showed a meaningful improvement of R0 resectability, as well as OS and/or DFS, compared with surgery (including surgery-alone and surgery plus postoperative adjuvant chemotherapy). Importantly, among these regimens, TPF regimen showed significant superiority in R0 resection rate (versus ECF regimen), OS (versus ECF regimen), DFS (versus PF and ECF regimens), and pCR (versus PF regimen). CONCLUSIONS: The taxane-based triplet regimen of TPF is likely the optimal neoadjuvant chemotherapy regimen for LAGC patients.

Ovarian cancer (OV) seriously damages women's health because of refractory OV and the development of platinum (Pt) resistance. New treatment strategies are urgently needed to deal with the treatment of cisplatin-resistant OV. Here, a reduction-sensitive pegylated Pt(IV) prodrug was synthesized by amidation of methoxy polyethylene glycol amine (PEG750-NH2) with monocarboxylic Pt(IV) prodrug (Pt(IV)-COOH). Then alantolactone (AL) loaded PEG-Pt(IV) nanocarriers (NP(Pt)@AL) were prepared. In the cisplatin-resistant model of OV, cancer cells actively ingest NP(Pt)@AL through endocytosis, and AL and Pt(II) were disintegrated and released under high intracellular reductant condition. The activity of thioredoxin reductase 1 (TrxR1) inhibited by AL and the adducts of Pt(II) with mitochondrial DNA (mDNA) can costimulate reactive oxygen species (ROS) and reactivate the mitochondrial pathway of apoptosis. Meanwhile, Pt(II) binds with nuclear DNA (nDNA) to jointly promote cell apoptosis. Both in vitro and in vivo results demonstrated that NP(Pt)@AL could effectively reverse the drug resistance and displayed excellent synergistic therapeutic efficacy on platinum-resistant OV with high safety. Therefore, reactivation of the mitochondrial pathway of apoptosis would be a potential strategy to improve the therapeutic effect of Pt-based chemotherapy and even reverse drug resistance.

PURPOSE: Platinum-based chemotherapy with or without immunotherapy is the mainstay of treatment for advanced stage non-small cell lung cancer (NSCLC) lacking a molecular driver alteration. Pre-clinical studies have reported that pharmacological ascorbate (P-AscH-) enhances NSCLC response to platinum-based therapy. We conducted a phase II clinical trial combining P-AscH- with carboplatin-paclitaxel chemotherapy. EXPERIMENTAL DESIGN: Chemotherapy naïve advanced stage NSCLC patients received 75 g ascorbate twice per week intravenously with carboplatin and paclitaxel every three weeks for four cycles. The primary endpoint was to improve tumor response per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 compared to the historical control of 20%. The trial was conducted as an optimal Simon's two-stage design. Blood samples were collected for exploratory analyses. RESULTS: The study enrolled 38 patients and met its primary endpoint with an objective response rate of 34.2% (p = 0.03). All were confirmed partial responses (cPR). The disease control rate was 84.2% (stable disease + cPR). Median progression-free and overall survival were 5.7 months and 12.8 months, respectively. Treatment-related adverse events (TRAE) included one grade 5 (neutropenic fever) and five grade 4 events (cytopenias). Cytokine and chemokine data suggest that the combination elicits an immune response. Immunophenotyping of peripheral blood mononuclear cells demonstrated an increase in effector CD8 T-cells in patients with a progression-free survival (PFS) ≥ 6 months. CONCLUSIONS: The addition of P-AscH- to platinum-based chemotherapy improved tumor response in advanced stage NSCLC. P-AscH- appears to alter the host immune response and needs further investigation as a potential adjuvant to immunotherapy.

PURPOSE: The current recommendation for patients with locoregionally advanced nasopharyngeal carcinoma (NPC) is cisplatin-based induction chemotherapy (IC) or adjuvant chemotherapy (AC) plus concurrent chemoradiotherapy (CRT). However, data on the optimal platinum doses for each phase of combined regimens are lacking. EXPERIMENTAL DESIGN: 742 patients with NPC in the NPC-0501 trial treated with CRT plus IC/AC and irradiated with intensity-modulated radiotherapy (IMRT) were analyzed. The optimal platinum dose to achieve the best overall survival (OS) in the concurrent and induction/adjuvant phases was studied. RESULTS: Evaluation of the whole series shows the optimal platinum dose was 160 mg/m2 in the concurrent and 260 mg/m2 in the induction/adjuvant phase. Repeating the analyses on 591 patients treated with cisplatin throughout (no replacement by carboplatin) confirmed the same results. The cohort with optimal platinum doses in both phases had better OS than the cohort suboptimal in both phases (stage III: 90% vs. 75%; stage IVA-B: 80% vs. 56%, at 5-year). Multivariable analyses confirmed optimal platinum doses in both phases versus suboptimal dose in each phase are significant independent factors for OS, with HR of 0.61 [95% confidence interval (CI), 0.41-0.91] and 0.67 (95% CI, 0.48-0.94), respectively. Treatment sequence was statistically insignificant after adjusting for platinum doses. CONCLUSIONS: Both concurrent and IC/AC are needed for locoregionally advanced NPC, even for patients irradiated by IMRT; the concurrent platinum dosage could be set at ≥160 mg/m2 when coupled with adequate induction/adjuvant dosage at ≥260 mg/m2 (or at least ≥240 mg/m2). To achieve these optimal dosages, IC-CRT at conventional fractionation is favored.

BACKGROUND: Kangai injection (KAI) is a well-known Chinese patent medicine applied for several different types of cancers in the clinic as an auxiliary therapeutic approach, which is refined from three herbal extracts (Astragalus, Ginseng and Matrine). PURPOSE: To systematically evaluate the effect of combination treatment of platinum-based chemotherapy and KAI on patients with advanced non-small-cell lung cancer (NSCLC). STUDY DESIGN: A meta-analysis of randomized clinical trials. MATERIALS AND METHODS: The randomized controlled trials (RCTs) about stage â ¢-â £ NSCLC using KAI combined platinum-based chemotherapy were electronically retrieved from eight electronic databases up to July 2021. We applied RevMan 5.4, Stata 16.0, TSA 0.9.5.10 Beta and GRADE Pro-GDT to evaluate the quality of the included RCTs and perform the meta-analysis. RESULTS: 19 RCTs were included, consisting a total sample size of 1,389 cases. Meta-analysis revealed that compared with chemotherapy alone, KAI combined with platinum-based chemotherapy was associated with significantly higher objective response rate (ORR) [RR = 1.36, 95%CI (1.21,1.54), p< 0.00001], higher disease control rate (DCR) [RR = 1.15, 95%CI (1.09,1.21), p< 0.00001], greater Karnofsky performance status (KPS) [RR = 1.75, 95%CI (1.41,2.18), p< 0.00001], lower white blood cell toxicity [RR = 0.67, 95%CI (0.55,0.82), p = 0.0001], lower platelet toxicity [RR = 0.60, 95%CI (0.47,0.75), P < 0.0001], and lower incidence of vomiting [RR = 0.66, 95%CI (0.57,0.76), p< 0.00001]. In terms of the immune function, KAI united with chemotherapy significantly raised the ratio of CD3+ cells [MD = 10.65, 95%CI (8.21,13.09), p< 0.00001], CD4+ cells [MD = 7.67, 95%CI (6.31,9.03), p< 0.00001], NK cells [MD = 4.97, 95%CI (3.03,6.92), p< 0.00001], and CD4+/ CD8+ [MD = 0.32, 95%CI (0.19,0.45), p< 0.00001], and decreased the percentage of CD8+ cells [MD = -5.56, 95%CI (-7.51,-3.61), p< 0.00001]. CONCLUSIONS: This meta-analysis identified that the combination treatment of KAI and platinum-based chemotherapy was more beneficial to patients with advanced NSCLC when compared to chemotherapy alone, which could significantly improve the clinical efficacy, enhance the immune function, and reduce chemotherapy toxicity. Our study provides a theoretical basis and treatment guidance for patients with NSCLC.

Triple negative breast cancer (TNBC) is prone to recurrence and metastasis, which is the subtype of poorest prognosis. Chemotherapy is the main treatment, although there is lack of effective adjuvant chemotherapy regimens. The unsatisfactory efficacy of chemotherapy has been a bottleneck in improving the outcome of TNBC. Platinum compounds act directly on DNA to kill tumor cells, and they have a stronger killing effect on tumor cells carrying DNA damage repair (DDR) defects, which is an important entry point to improve the efficacy of TNBC. Biomarkers for predicting the efficacy of platinum drugs in TNBC treatment have always been a hot topic. The DDR pathway contains a large number of related genes, and recent studies have shown that deficiencies in the DDR pathway may be associated with the efficacy of platinum drugs, which is expected to be a biomarker for predicting the efficacy of platinum drugs in breast cancer treatment.

Imaging-guided chemo-phototherapy based on a single nanoplatform has a great significance to improve the efficiency of cancer therapy and diagnosis. However, high drug content, no burst release and real-time tracking of nanodrugs are the three main challenges for this kind of multifunctional nanotheranostics. In this work, we developed an innovative theranostic nanoplatform based on a Pt(IV) prodrug and a near-infrared (NIR) photosensitizer. A Pt(IV) prodrug and a cyanine dye (HOCyOH, Cy) were copolymerized and incorporated into the main chain of a polyprodrug (PCPP), which self-assembled into nanoparticles (NPs) with â¼27.61% Cy loading and â¼9.37% Pt loading, respectively. PCPP NPs enabled reduction-triggered backbone cleavage of polyprodrugs and bioactive Pt(II) release; Cy could be activated under 808 nm laser irradiation to produce local hyperthermia and reactive oxygen species (ROS) for phototherapy. Moreover, PCPP NPs with extremely high Cy and Pt heavy metal contents in the backbone of the polyprodrug could directly track the nanodrugs themselves via near-infrared fluorescence (NIRF) imaging, photothermal imaging, and computed tomography (CT) imaging in vitro and in vivo. As revealed by trimodal imaging, PCPP NPs were found to exhibit excellent tumor accumulation and antitumor efficiency after intravenous injection into H22-tumor-bearing mice. The dual-drug backboned polyprodrug nanoplatform exhibited great potential for bioimaging and combined chemo-phototherapy.

Triple negative breast cancer (TNBC) is prone to recurrence and metastasis, which is the subtype of poorest prognosis. Chemotherapy is the main treatment, although there is lack of effective adjuvant chemotherapy regimens. The unsatisfactory efficacy of chemotherapy has been a bottleneck in improving the outcome of TNBC. Platinum compounds act directly on DNA to kill tumor cells, and they have a stronger killing effect on tumor cells carrying DNA damage repair (DDR) defects, which is an important entry point to improve the efficacy of TNBC. Biomarkers for predicting the efficacy of platinum drugs in TNBC treatment have always been a hot topic. The DDR pathway contains a large number of related genes, and recent studies have shown that deficiencies in the DDR pathway may be associated with the efficacy of platinum drugs, which is expected to be a biomarker for predicting the efficacy of platinum drugs in breast cancer treatment.

BACKGROUND: Lung cancer is the leading cause of death among cancer patients worldwide. Close to 85% of lung cancer pathology types are nonsmall cell lung cancer (NSCLC). With advances in medicine, the survival rate of early-stage NSCLC has improved. Nevertheless, about 70% of patients are diagnosed at an advanced stage, and chemotherapy is the primary treatment option. Chemotherapy causes toxic side effects such as bone marrow suppression, gastrointestinal reactions, and damage to vital organs, which are difficult for patients to tolerate. Many published literatures have reported that Shenmai injection (SMI) combined with platinum-containing first-line chemotherapy regimen for NSCLC can improve the recent efficacy, reduce toxic side effects and improve the quality of life. However, most of the studies were small samples and lacked persuasive power, while controversies existed among individual studies. Therefore, this study used meta-analysis to further evaluate the effects of SMI combined with platinum-containing first-line chemotherapy on the quality of life, immune function and prognosis of patients with NSCLC. METHODS: Wanfang, Chinese Biomedical Literature Database, Chinese National Knowledge Infrastructure, the Chongqing VIP Chinese Science and Technology Periodical Database, PubMed, Embase, and Web of Science databases were searched. The search was scheduled from the establishment of the database to September 2021. All randomized controlled trials comparing SMI in combination with platinum-containing first-line chemotherapy to platinum-containing first-line chemotherapy alone for the treatment of NSCLC were searched and evaluated for inclusion. Two investigators independently performed study selection, data extraction and synthesis. The Cochrane Risk of Bias tool was used to assess the risk of bias in the randomized controlled trials. Stata 16.0 software was used for meta-analysis. RESULTS: The results of this meta-analysis will be submitted to a peer-reviewed journal for publication. CONCLUSION: This study comprehensively evaluated the effects of SMI combined with platinum-containing first-line chemotherapy on quality of life, immune function and prognosis in patients with NSCLC to provide an evidence-based basis for clinical practice. ETHICS AND DISSEMINATION: The private information from individuals will not be published. This systematic review should also not damage participants' rights. Ethical approval was not available. The results may be published in a peer-reviewed journal or disseminated in relevant conferences.OSF Registration number: DOI 10.17605/OSF.IO/AMKDC.

BACKGROUND: The nutritional status can potentially affect the efficacy of cancer therapy. The Geriatric Nutritional Risk Index (GNRI), a simple index for evaluating nutritional status calculated from body weight and serum albumin levels, has been reported to be associated with the prognosis of various diseases. However, the relationships between GNRI and the efficacy of platinum-based chemotherapy in patients with non-small-cell lung cancer (NSCLC) are unknown. METHODS: The pretreatment levels of GNRI were retrospectively evaluated in 148 chemo-naïve patients with advanced NSCLC who received first-line platinum-based chemotherapy and scored as low or high. RESULTS: Patients with a high GNRI had a significantly higher overall response rate (ORR; 44.5% [95% confidence interval {CI} = 35.6%-53.9%] vs. 15.8% [95% CI = 7.4%-30.4%, p = 0.002), longer median progression-free survival (PFS; 6.3 months [95% CI = 5.6-7.2 months] vs. 3.8 months [95% CI = 2.5-4.7 months], p < 0.001), and longer median overall survival (OS; 22.8 months [95% CI = 16.7-27.2 months] vs. 8.5 months [95% CI = 5.4-16.0 months], p < 0.001) than those with low GNRI. High GNRI was independently predictive of better ORR in multivariate logistic regression analysis and longer PFS and OS in multivariate Cox proportional hazard analyses. In 71 patients who received second-line non-platinum chemotherapy, patients with high GNRI exhibited significantly longer PFS and OS than those with low GNRI (both p < 0.001). CONCLUSIONS: GNRI was predictive of prolonged survival in patients with NSCLC who received first-line platinum-based chemotherapy and second-line non-platinum chemotherapy. Assessment of the nutritional status may be useful for predicting the efficacy of chemotherapy.

BACKGROUND: Non-small-cell lung cancer (NSCLC) is a major health burden in many countries. This review aimed to evaluate the efficacy of traditional herbal medicine (THM) combined with first-line platinum-based chemotherapy (PBCT) for the treatment of advanced NSCLC. METHODS: From inception to April 2021, relevant studies were retrieved from 9 electronic databases. Randomized controlled trials (RCTs) comparing survival outcomes of THMâ+âPBCT treatment with PBCT treatment in patients with advanced NSCLC were reviewed. The risk of bias was evaluated using the Cochrane Risk of Bias Tool. Overall survival, 1-year survival, progression-free survival or time to progression, tumor response rate, and adverse effects were analyzed. RESULTS: Sixteen RCTs comprising 1445 patients were included. The meta-analysis indicated that THMâ+âPBCT treatment, compared to PBCT alone, could improve overall survival (median survival ratioâ=â1.24, 95% confidence intervals [CI] [1.11, 1.39], Pâ<â.001), progression-free survival/time to progression (median survival ratioâ=â1.22, 95% CI [1.09, 1.37], Pâ<â.001), and the 1-year survival rate (risk ratio [RR]â=â1.56, 95% CI [1.31, 1.86], Pâ<â.001). THMâ+âPBCT also led to a higher tumor response rate (RRâ=â1.39, 95% CI [1.22, 1.59], Pâ<â.001) and lower incidence of thrombocytopenia (RRâ=â0.72, 95% CI [0.56, 0.92], Pâ=â.009) and nausea/vomiting (RRâ=â0.35, 95% CI [0.21, 0.57], Pâ<â.001), while there was no significant effect observed on leukopenia (RRâ=â0.68, 95% CI [0.34, 1.36], Pâ=â.27). CONCLUSION: THM, when used in combination with PBCT, might increase survival and the tumor response rate while decreasing the side effects caused by chemotherapy in patients with advanced NSCLC. However, considering the limited methodological qualities of the included trials, more rigorous RCTs are needed.

Combined therapeutic strategies for bacterial infection have attracted worldwide attention owing to their faster and more effective therapy with fewer side effects compared with monotherapy. In this work, gold-platinum nanodots (AuPtNDs) are simply and quickly synthesized by a one-step method. They not only exhibit powerful peroxidase-like activity but also confer a higher affinity for hydrogen peroxide (H2O2), which is 3.4 times that of horseradish peroxidase. Under 808 nm laser irradiation, AuPtNDs also have excellent photothermal conversion efficiency (50.53%) and strong photothermal stability. Excitingly, they can combat bacterial infection through the combination of chemodynamic and photothermal therapy. In vitro antibacterial results show that the combined antibacterial strategy has a broad-spectrum antibacterial property against both Escherichia coli (Gram negative, 97.1%) and Staphylococcus aureus (Gram positive, 99.3%). Animal experiments further show that nanodots can effectively promote the healing of bacterial infection wounds. In addition, owing to good biocompatibility and low toxicity, they are hardly traceable in the main organs of mice, which indicates that they can be well excreted through metabolism. These results reveal the application potential of AuPtNDs as a simple and magic multifunctional nanoparticle in antibacterial therapy and open up new applications for clinical anti-infective therapy in the near future.
