Clinical outcomes of second-line chemotherapy in patients with advanced pancreatic adenocarcinoma:a real-world study

Objective:Little progress has been made in recent years using first-line chemotherapy,including gemcitabine combined with nab-paclitaxel,FOLFIRINOX,and NALIRIFOX,for advanced pancreatic adenocarcinoma(APC).In addition,the optimal second-line chemotherapy regimen has not been determined.This study aimed to compare the effectiveness of different types of second-line chemotherapy for APC.Methods:Patients with APC who received first-line treatment from January 2008 to January 2021 were considered eligible for this retrospective analysis.The primary and secondary endpoints were overall survival(OS)and progression-free survival(PFS),respectively.Results:Four hundred and thirty-seven and 617 patients were treated with 5-fluorouracil-and gemcitabine-based chemotherapy as first-line treatment,respectively.Demographic and clinical features,except age and liver metastasis,were comparable between the two groups(P<0.05).The median OS was 8.8 and 7.8 months in patients who received a 5-fluorouracil-and gemcitabine-based combined regimen for first-line therapy,respectively(HR=1.244,95%CI=1.090–1.419;P<0.001).The median OS was 5.6 and 1.9 months in patients who received second-line chemotherapy and supportive care,respectively(HR=0.766,95%CI=0.677–0.867;P<0.001).The median PFS was not significantly differently between gemcitabine or 5-fluorouracil monotherapy and combination therapy.Conclusions:A 5-fluorouracil-or gemcitabine-based combined regimen was shown to be as effective as a single 5-fluorouracil or gemcitabine regimen as second-line therapy for patients with APC.

Clinical study of docetaxel-vinorelbine as second-line chemotherapy in advanced non-small cell lung cancer

Objective： To evaluate the efficacy and toxicity of docetaxel and vinorelbine as second-line chemotherapy in the treatment of advanced non-small cell lung cancer （NSCLC）. Methods： 48 histologically or cytologically confirmed NSCLC patients with progressive or recurrent disease after first-line treatment were treated with docetaxel and vinoretbine. The chemotherapy included vinorelbine （25 mg/m^2） on days 1,5 and docetaxel （60 mg/m^2） on day 1. The treatment was repeated every 3 weeks. Patients receiving at least two cycles were evaluated for efficacy and toxicity. Results： Of 48 patients, 1 patient achieved complete response and 16 achieved partial response. Overall response rate for all 48 patients was 35.4% （17/48）. Main hematologic toxicities included neutropenia （60.4%） and febrile neutropenia （29.2%） and non-hematologic toxicities were mild. Conclusion： The combination of docetaxel-vinorelbine as second-line chemotherapy is an effective regimen with manageable toxicity for the treatment of advanced NSCLC. Further studies may confirm these results.

Study protocol of the Asian XELIRI ProjecT(AXEPT):a multinational,randomized,non-inferiority,phase Ⅲ trial of second-line chemotherapy for metastatic colorectal cancer, comparing the eicacy and safety of XELIRI with or without bevacizumab versus FOLFIRI w

Background: Capecitabine and irinotecan combination therapy(XELIRI) has been examined at various dose levels to treat metastatic colorectal cancer(m CRC). Recently, in the Association of Medical Oncology of the German Cancer Society(AIO) 0604 trial, tri?weekly XELIRI plus bevacizumab, with reduced doses of irinotecan(200 mg/m^2 on day 1) and capecitabine(1600 mg/m^2 on days 1–14), repeated every 3 weeks, has shown favorable tolerability and eicacy which were comparable to those of capecitabine and oxaliplatin(XELOX) plus bevacizumab. The doses of capecit?abine and irinotecan in the AIO trial are considered optimal. In a phase I/II study, XELIRI plus bevacizumab(BIX) as second?line chemotherapy was well tolerated and had promising eicacy in Japanese patients.Methods: The Asian XELIRI Projec T(AXEPT) is an East Asian collaborative, open?labelled, randomized, phase Ⅲ clinical trial which was designed to demonstrate the non?inferiority of XELIRI with or without bevacizumab versus standard FOLFIRI(5?fluorouracil, leucovorin, and irinotecan combination) with or without bevacizumab as second?line chemo?therapy for patients with m CRC. Patients with 20 years of age or older, histologically conirmed m CRC, Eastern Coop?erative Oncology Group performance status 0–2, adequate organ function, and disease progression or intolerance of the irst?line regimen will be eligible. Patients will be randomized(1:1) to receive standard FOLFIRI with or with?out bevacizumab(5 mg/kg on day 1), repeated every 2 weeks(FOLIRI arm) or XELIRI with or without bevacizumab(7.5 mg/kg on day 1), repeated every 3 weeks(XELIRI arm). A total of 464 events were estimated as necessary to show non?inferiority with a power of 80% at a one?sided α of 0.025, requiring a target sample size of 600 patients. The 95% conidence interval(CI) upper limit of the hazard ratio was pre?speciied as less than 1.3.Conclusion: The Asian XELIRI Projec T is a multinational phase III trial being conducted to provide evidence for XELIRI with or without bevacizumab as a second?line treatment option of mCRC.

Raltitrexed + irinotecan as second-line chemotherapy in elderly patients with advanced colorectal cancer

Aims and Background: Irinotecan is a standard option for relapsed/refractory advanced colo- rectal cancer. Combination with raltitrexed and irinotecan at lower than MTD doses should preserve disease stabilisation while decreasing toxicity. Patients and Methods: From January 2004 to April 2009, we analyzed, retrospectively, our data on irinotecan + raltitrexed, fixed doses, as a second-line chemotherapy in elderly pa- tients (>70 years) with advanced colorectal can- cer after failure of oxaliplatin based chemothera- py twenty-three patients were evaluated. Iri- notecan 350 mg + raltitrexed 2.6 mg were given every 3 weeks. Tumo r measurements were ob- tained after every third course of therapy. Toxic- ity was assessed weekly using the National Cancer Institute Common Toxicity Criteria, ver- sion 2. Results: The median number of treatment courses received per patient was 4 (range, 1 - 8). All pa-tients were assessable for toxicity and 21 for response. The most frequently observed severetoxicities were diarrhea (grade 2, 13%) No cases of significant neutropenia occurred. Ob- jective partial responses were observed in 3 pa- tients (13%). An additional 10 patients (43%) had stable disease as their best response. To date, 12 patients have progressed with a median time- to-progression of 4.3 months and a median sur- vival of 8.3 months. Conclusions: A three weekly irinotecan + raltitrexed administration can indu- ce tumor control in elderly patients with advanc- ed colorectalcancer that has progressed during or shortly after oxaliplatin-based chemotherapy. The diarrhea by irinotecan, seems mitigated by coad-ministration of a smaller dose of

Comparing effectiveness and safety of paclitaxel plus raltitrexed vs. paclitaxel alone in second-line palliative chemotherapy for metastatic gastric adenocarcinoma: A randomized phase Ⅱ clinical trial

Objective:Paclitaxel(P)is a standard second-line chemotherapy in the treatment of advanced gastric cancer.This study compared the clinical outcome of a paclitaxel plus raltitrexed(RP)regimen as second-line treatment in metastatic gastric cancer(MGC)patients.Methods:An open,randomized,multi-center phase Ⅱ clinical trial was conducted involving 148 patients who were randomly assigned and treated with RP[raltitrexed(3 mg/m^(2)on day 1)and paclitaxel(135 mg/m^(2)on day 1 every 3 weeks)]or P[paclitaxel(135 mg/m^(2)on day 1 every 3 weeks)]as 2nd-line chemotherapy.The primary endpoint was progression-free survival(PFS).The secondary endpoints were the overall response rate(ORR),overall survival(OS),and safety.Results:PFS had a tendency to be prolonged with RP compared to P(2.7 months vs.1.7 months;P=0.148).OS was also prolonged with RP compared to P(10.2 months vs.6.1 months;P=0.140).The ORR was equal in the RP and P groups(6.8%and 4.0%;P=0.72).The disease control rate(DCR)in the RP and P groups was 56.2%and 36.0%,respectively.Grade 3-4 treatment-related adverse events occurred in 36.2%(RP)and 28.2%(P)of patients.Frequent grade 3-4 toxicities for RP and P were neutropenia(11.0%and 4.0%),anemia(1.4%and 4.0%),and thrombocytopenia(1.4%and 5.3%),and all grades of peripheral neurotoxicity(12.3%vs.17.3%).All grades of hepatic toxicity were demonstrated for the RP and P groups based on elevated aminotransferase levels(27.4%and 14.1%).Subgroup analysis shows if MGC was combined with ascites or peritoneal involvement,the OS of the RP regimen was longer(P=0.05).Conclusions:Second-line palliative chemotherapy with RP was shown to prolong the PFS and OS,especially among patients with ascites or peritoneal involvement,which warrants confirmation using larger sample studies.

Cost-effectiveness analysis of second-line chemotherapy strategies for patients with advanced non-squamous non-small cell lung cancer

Lung cancer is the most widespread type of cancer and the primary cause of cancer-related death in the world.In this study,we aimed to analyze the cost-effectiveness of second-line chemotherapy strategies based on gemcitabine,pemetrexed,and docetaxel for advanced non-squamous non-small cell lung cancer patients in China.A Markov model based on three states,progression-free survival,progressed survival and death,was constructed to simulate the progression of the disease in a 6-year horizon.Sensitivity analysis was performed to evaluate the robustness of the model.The primary outcome of the model was the incremental cost-effectiveness ratio at a willingness-to-pay threshold of 3×per capita GDP of China in 2018($29383).The baseline model results showed that the quality-adjusted life years over the course of the disease associated with second-line chemotherapy strategies were 0.233,0.417 and 0.272 for gemcitabine,pemetrexed and docetaxel,respectively,and the corresponding total costs were$5321.02,$12143.94,and$9479.42.Gemcitabine,pemetrexed and docetaxel resulted in the incremental cost-effectiveness ratios of$37081.09 and$106625.64 per quality-adjusted life year gained.The incremental cost-effectiveness ratio of pemetrexed and docetaxel compared with gemcitabine exceeded the willingness-to-pay threshold.One-way sensitivity analysis showed that the utility value of gemcitabine in the progressed survival state was the most influential parameter.

Chemotherapy beyond second-line in advanced gastric cancer

Patients with advanced gastric cancer(AGC) can be treated with multiple lines of chemotherapy. Although several randomized trials have demonstrated the benefit of second-line chemotherapy compared with best supportive care, there is no evidence that further lines of chemotherapy will result in substantial prolongation of survival. Despite this, the practice of offering chemotherapy beyond second-line agents to AGC patients is not uncommon if their performance status is well-preserved and they are willing to receive subsequent active treatments. The choice of chemotherapeutic agents depends on the patient's prior regimens. However, there are important controversial issues in the salvage setting of AGC, including a subset of patients who may benefit from chemotherapy, that still remain unanswered. This report reviews the available evidence regarding the impact of third- and subsequent lines of chemotherapy on survival and quality of life in patients with AGC.

Oral chemotherapy for second-line treatment in patients with gemcitabine-refractory advanced pancreatic cancer

BACKGROUND There is no standard therapy for second-line treatment of gemcitabine-refractory pancreatic cancer patients with poor performance status.A combination of chemotherapy drugs 5-fluorouracil(5-FU),leucovorin,irinotecan,and oxaliplatin(FOLFIRINOX)or 5-fluorouracil/leucovorin plus nanoliposomal irinotecan can be considered as second-line treatment for such patients;however,due to toxicity,none of the regimens are recommended for patients with poor performance.Capecitabine or S-1 has relatively low toxicity and can be considered a treatment option for gemcitabine-refractory pancreatic cancer.AIM To investigate the efficacy and toxicity of oral chemotherapy as second-line treatment in patients with pancreatic cancer.METHODS Patients who had progressive disease after first-line gemcitabine-based chemotherapy were retrospectively analyzed between January 2011 and December 2018.They were treated with capecitabine or S-1 as the second-line treatment.Capecitabine was administered as a 2500 mg/m2 divided dose on days 1-14,followed by a 1-wk rest.S-1 was taken orally based on the patient’s body surface area for 28 d,followed by 2-wk of rest.Progression-free survival and overall survival were used to compare efficacy of capecitabine and S-1.RESULTS Of the 81 patients,41 were treated with capecitabine and 40 with S-1.The median time to treatment failure in both groups was 1.5 mo(P=0.425).The objective response rate was similar in the two groups:9.8%with capecitabine and 2.5%with S-1(P=0.359).Median progression-free survival was longer in the S-1 group than in the capecitabine group(S-12.7 mo,capecitabine 2.0 mo,P=0.003).There was no significant difference in the median overall survival between the capecitabine and S-1 groups(4.3 mo vs 5.0 mo,P=0.092).Grade 3 or 4 hand-foot syndrome was significantly more common in the capecitabine group than in the S-1 group(14.6%vs 0%,P=0.026).CONCLUSION Capecitabine or S-1 can be used as a second-line treatment for patients with advanced pancreatic cancer with poor performance status after progression to a gemcitabine-based regimen.

Hepatic arterial infusion chemotherapy with anti-angiogenesis agents and immune checkpoint inhibitors for unresectable hepatocellular carcinoma and meta-analysis

BACKGROUND Hepatic arterial infusion chemotherapy(HAIC)has been proven to be an ideal choice for treating unresectable hepatocellular carcinoma(uHCC).HAIC-based treatment showed great potential for treating uHCC.However,large-scale studies on HAIC-based treatments and meta-analyses of first-line treatments for uHCC are lacking.AIM To investigate better first-line treatment options for uHCC and to assess the safety and efficacy of HAIC combined with angiogenesis inhibitors,programmed cell death of protein 1(PD-1)and its ligand(PD-L1)blockers(triple therapy)under real-world conditions.METHODS Several electronic databases were searched to identify eligible randomized controlled trials for this meta-analysis.Study-level pooled analyses of hazard ratios(HRs)and odds ratios(ORs)were performed.This was a retrospective single-center study involving 442 patients with uHCC who received triple therapy or angiogenesis inhibitors plus PD-1/PD-L1 blockades(AIPB)at Sun Yat-sen University Cancer Center from January 2018 to April 2023.Propensity score matching(PSM)was performed to balance the bias between the groups.The Kaplan-Meier method and cox regression were used to analyse the survival data,and the log-rank test was used to compare the suvival time between the groups.RESULTS A total of 13 randomized controlled trials were included.HAIC alone and in combination with sorafenib were found to be effective treatments(P values for ORs:HAIC,0.95;for HRs:HAIC+sorafenib,0.04).After PSM,176 HCC patients were included in the analysis.The triple therapy group(n=88)had a longer median overall survival than the AIPB group(n=88)(31.6 months vs 14.6 months,P<0.001)and a greater incidence of adverse events(94.3%vs 75.4%,P<0.001).CONCLUSION This meta-analysis suggests that HAIC-based treatments are likely to be the best choice for uHCC.Our findings confirm that triple therapy is more effective for uHCC patients than AIPB.

Efficacy of hepatic arterial infusion chemotherapy and its combination strategies for advanced hepatocellular carcinoma:A network meta-analysis

BACKGROUND With the rapid progress of systematic therapy for hepatocellular carcinoma(HCC),therapeutic strategies combining hepatic arterial infusion chemotherapy(HAIC)with systematic therapy arised increasing concentrations.However,there have been no systematic review comparing HAIC and its combination strategies in the first-line treatment for advanced HCC.AIM To investigate the efficacy and safety of HAIC and its combination therapies for advanced HCC.METHODS A network meta-analysis was performed by including 9 randomized controlled trails and 35 cohort studies to carry out our study.The outcomes of interest comprised overall survival(OS),progression-free survival(PFS),tumor response and adverse events.Hazard ratios(HR)and odds ratios(OR)with a 95% confidence interval(CI)were calculated and agents were ranked based on their ranking probability.RESULTS HAIC outperformed Sorafenib(HR=0.55,95%CI:0.42-0.72;HR=0.51,95%CI:0.33-0.78;OR=2.86,95%CI:1.37-5.98;OR=5.45,95%CI:3.57-8.30;OR=7.15,95%CI:4.06-12.58;OR=2.89,95%CI:1.99-4.19;OR=0.48,95%CI:0.25-0.92,respectively)and transarterial chemoembolization(TACE)(HR=0.50,95%CI:0.33-0.75;HR=0.62,95%CI:0.39-0.98;OR=3.08,95%CI:1.36-6.98;OR=2.07,95%CI:1.54-2.80;OR=3.16,95%CI:1.71-5.85;OR=2.67,95%CI:1.59-4.50;OR=0.16,95%CI:0.05-0.54,respectively)in terms of efficacy and safety.HAIC+lenvatinib+ablation,HAIC+ablation,HAIC+anti-programmed cell death 1(PD-1),and HAIC+radiotherapy had the higher likelihood of providing better OS and PFS outcomes compared to HAIC alone.HAIC+TACE+S-1,HAIC+lenvatinib,HAIC+PD-1,HAIC+TACE,and HAIC+sorafenib had the higher likelihood of providing better partial response and objective response rate outcomes compared to HAIC.HAIC+PD-1,HAIC+TACE+S-1 and HAIC+TACE had the higher likelihood of providing better complete response and disease control rate outcomes compared to HAIC alone.CONCLUSION HAIC proved more effective and safer than sorafenib and TACE.Furthermore,combined with other interventions,HAIC showed improved efficacy over HAIC monotherapy according to the treatment ranking analysis.

Local dose-dense chemotherapy for triple-negative breast cancer via minimally invasive implantation of 3D printed devices

Dose-dense chemotherapy is the preferred first-line therapy for triple-negative breast cancer(TNBC),a highly aggressive disease with a poor prognosis.This treatment uses the same drug doses as conventional chemotherapy but with shorter dosing intervals,allowing for promising clinical outcomes with intensive treatment.However,the frequent systemic administration used for this treatment results in systemic toxicity and low patient compliance,limiting therapeutic efficacy and clinical benefit.Here,we report local dose-dense chemotherapy to treat TNBC by implanting 3D printed devices with timeprogrammed pulsatile release profiles.The implantable device can control the time between drug releases based on its internal microstructure design,which can be used to control dose density.The device is made of biodegradable materials for clinical convenience and designed for minimally invasive implantation via a trocar.Dose density variation of local chemotherapy using programmable release enhances anti-cancer effects in vitro and in vivo.Under the same dose density conditions,device-based chemotherapy shows a higher anticancer effect and less toxic response than intratumoral injection.We demonstrate local chemotherapy utilizing the implantable device that simulates the drug dose,number of releases,and treatment duration of the dose-dense AC(doxorubicin and cyclophosphamide)regimen preferred for TNBC treatment.Dose density modulation inhibits tumor growth,metastasis,and the expression of drug resistance-related proteins,including p-glycoprotein and breast cancer resistance protein.To the best of our knowledge,local dose-dense chemotherapy has not been reported,and our strategy can be expected to be utilized as a novel alternative to conventional therapies and improve anti-cancer efficiency.

Efficacy of chemotherapy containing bevacizumab in patients with metastatic colorectal cancer according to programmed cell death ligand 1

BACKGROUND Bevacizumab,an anti-vascular endothelial growth factor(VEGF)monoclonal antibody,inhibits angiogenesis and reduces tumor growth.Serum VEGF-C,lactate dehydrogenase,and inflammatory markers have been reported as predictive markers related to bevacizumab treatment.Programmed cell death ligand 1(PD-L1)could act upon VEGF receptor 2 to induce cancer cell angiogenesis and metastasis.AIM To investigate the efficacy of bevacizumab-containing chemotherapy in patients with metastatic colorectal cancer(CRC)according to the expression of PD-L1.METHODS This analysis included CRC patients who received bevacizumab plus FOLFOX or FOLFIRI as first-line therapy between June 24,2014 and February 28,2022,at Samsung Medical Center(Seoul,South Korea).Analysis of patient data included evaluation of PD-L1 expression by the combined positive score(CPS).We analyzed the efficacy of bevacizumab according to PD-L1 expression status in patients with CRC.RESULTS A total of 124 patients was included in this analysis.Almost all patients were treated with bevacizumab plus FOLFIRI or FOLFOX as the first-line chemotherapy.While 77%of patients received FOLFOX,23%received FOLFIRI as backbone first-line chemotherapy.The numbers of patients with a PD-L1 CPS of 1 or more,5 or more,or 10 or more were 105(85%),64(52%),and 32(26%),respectively.The results showed no significant difference in progression-free survival(PFS)and overall survival(OS)with bevacizumab treatment between patients with PDL1 CPS less than 1 and those with PD-L1 CPS of 1 or more(PD-L1<1%vs PD-L1≥1%;PFS:P=0.93,OS:P=0.33),between patients with PD-L1 CPS less than 5 and of 5 or more(PD-L1<5%vs PD-L1≥5%;PFS:P=0.409,OS:P=0.746),and between patients with PD-L1 CPS less than 10 and of 10 or more(PD-L1<10%vs PD-L1≥10%;PFS:P=0.529,OS:P=0.568).CONCLUSION Chemotherapy containing bevacizumab can be considered as first-line therapy in metastatic CRC irrespective of PD-L1 expression.

Real-world evidence on first-and second-line palliative chemotherapy in advanced pancreatic cancer

In spite of recent diagnostic and therapeutic advances,the prognosis of pancreatic ductal adenocarcinoma(PDAC)remains very poor.As most patients are not amenable to curative intent treatments,optimized palliative management is highly needed.One key question is to what extent promising results produced by randomized controlled trials(RCTs)correspond to clinically meaningful outcomes in patients treated outside the strict frames of a clinical trial.To answer such questions,real-world evidence is necessary.The present paper reviews and discusses the current literature on first-and second-line palliative chemotherapy in PDAC.Notably,a growing number of studies report that the outcomes of the two predominant first-line multidrug regimens,i.e.gemcitabine plus nabpaclitaxel(GnP)and folfirinox(FFX),is similar in RCTs and real-life populations.Outcomes of second-line therapy following failure of first-line regimens are still dismal,and considerable uncertainty of the optimal management remains.Additional RCTs and real-world evidence studies focusing on the optimal treatment sequence,such as FFX followed by GnP or vice versa,are urgently needed.Finally,the review highlights the need for prognostic and predictive biomarkers to inform clinical decision making and enable personalized management in advanced PDAC.

Shenqi Fuzheng injection alleviates chemotherapy-induced cachexia by restoring glucocorticoid signaling in hypothalamus

Chemotherapy-induced cachexia(CIC)is a debilitating condition characterized by weight loss,muscle atrophy,and anorexia[1].While peripheral mechanisms of cachexia have been extensively studied,the involvement of the central nervous system(CNS)in CIC is often overlooked.Chemotherapeutic drugs cause stress responses and inflammation,which may impact the hypothalamus and disrupt systemic energy and neuroendocrine functions.Understanding hypothalamic roles in regulating these processes can provide insights into CIC's mechanisms and aid in developing novel therapies.

Screening of Myocardial Cardiotoxicity Induced by Anticancer Chemotherapy and the Importance of Global Longitudinal Strain

Introduction: The improvement of survival in patients with cancer and the expansion of therapeutic options have led to the emergence of a new profile of cardiotoxicity, specifically associated with antimitotic agents. Our study aimed to assess the incidence of chemotherapy-induced myocardial toxicity in patients with cancer. Patients and Methods: We conducted a looking-forward longitudinal cohort study including all patients admitted to the Cardiology departments of Aristide le Dantec Hospital and Dalal Jamm National Hospital Centre for apre-chemotherapy check-up. The included patients did not undergo any pre-existing cardiopathy. Results: Over a period of two years ranging from January 2019 to December 2021, a total of 37 patients were included in the study. Notably, there was a female predominance (92%) with an average age of 49.7 years ± 13.69. Breast cancer accounted for 70% of the neoplasms. Laboratory findings revealed moderate anemia in 19 patients (51%). At inclusion, the left ventricle (LV) was of normal size (LV diastole at 44.46 ± 4.97 mm). The systolic function of the left ventricle was normal in all patients, with an average ejection fraction (EF) of 63.1% ± 5.80 and a mean global longitudinal strain (GLS) of −20.4% ± 2.58. The most commonly used agents were anthracyclines. During follow-up, 3 patients (8.1%) developed clinical symptoms of left heart failure, and LV dysfunction on echocardiography was observed in 5 (13.5%) patients, with a significant decrease in EF Conclusion: The incidence of cardiac toxicity is not negligible, hence the importance of early screening. Strain imaging is an essential tool that should be performed as part of the assessment before chemotherapy and re-evaluated during treatment.

Perioperative chemotherapy improves survival of patients with locally advanced diffuse gastric cancer

BACKGROUND Whether patients with diffuse gastric cancer,which is insensitive to chemo-therapy,can benefit from neoadjuvant or adjuvant chemotherapy has long been controversial.AIM To investigate whether perioperative chemotherapy can improve survival of patients with locally advanced diffuse gastric cancer.METHODS A total of 2684 patients with locally advanced diffuse gastric cancer from 18 population-based cancer registries in the United States were analyzed.RESULTS Compared with surgery alone,perioperative chemotherapy improved the prognosis of patients with locally advanced gastric cancer.Before stabilized inverse probability of treatment weighting(IPTW),the median overall survival(OS)times were 40.0 months and 13.0 months(P<0.001),respectively.After IPTW,the median OS times were 33.0 months and 17.0 months(P<0.001),respectively.Neoadjuvant chemotherapy did not improve the prognosis of patients with locally advanced gastric cancer compared with adjuvant chemotherapy after IPTW.After IPTW,the median OS times were 38.0 months in the neoadjuvant chemotherapy group and 42.0 months in the adjuvant chemotherapy group(P=0.472).CONCLUSION Patients with diffuse gastric cancer can benefit from perioperative chemotherapy.There was no significant difference in survival between patients who received neoadjuvant chemotherapy and those who received adjuvant chemotherapy.

Nutritional Supplement Ocoxin® Combined with Gemcitabine-Based Chemotherapy in Patients with Advanced Pancreatic Adenocarcinoma

Background: the quality of life (QoL) of patients with pancreatic ductal adenocarcinoma (PDAC), with its limited survival, can be affected by chemotherapy-induced toxicity. The main objective was to evaluate the effect of introducing ocoxin oral solution (OOS) in combination with standard therapy on quality of life. Methods: Thirty patients were enrolled in an exploratory, prospective, single-centre clinical trial in the oncology department of “Hermanos Ameijeiras” University Hospital in Havana, Cuba. Quality of life was measured using the EORTC QLQ-C30 questionnaire and toxicity was assessed using the NCI-CTC-AE classification version 5.0. Results: There was stability in the scores over time for overall QoL and the functional scale criteria, while in terms of symptoms, fatigue, pain and loss of appetite were reduced. No grade 3 - 4 adverse events (AEs) were recorded, and only 14.9% of toxicities were classified as grade 2, and these were considered to be unrelated to OOS. Biochemical and nutritional parameters were normalised at 12 months compared to the baseline values. Conclusions: This clinical study is the first report of the use of OOS in patients with advanced pancreatic cancer, and demonstrates that it is able to maintain optimal quality of life with reduced severity of toxicity during and after combination treatment with gemcitabine-based chemotherapy.

Effects of neoadjuvant chemotherapy vs chemoradiotherapy in the treatment of esophageal adenocarcinoma:A systematic review and meta-analysis

BACKGROUND Neoadjuvant therapy is an essential modality for reducing the clinical stage of esophageal cancer;however,the superiority of neoadjuvant chemotherapy(nCT)or neoadjuvant chemoradiotherapy(nCRT)is unclear.Therefore,a discussion of these two modalities is necessary.AIM To investigate the benefits and complications of neoadjuvant modalities.METHODS To address this concern,predefined criteria were established using the PICO protocol.Two independent authors performed comprehensive searches using predetermined keywords.Statistical analyses were performed to identify significant differences between groups.Potential publication bias was visualized using funnel plots.The quality of the data was evaluated using the Risk of Bias Tool 2(RoB2)and the GRADE approach.RESULTS Ten articles,including 1928 patients,were included for the analysis.Significant difference was detected in pathological complete response(pCR)[P<0.001;odds ratio(OR):0.27;95%CI:0.16-0.46],30-d mortality(P=0.015;OR:0.4;95%CI:0.22-0.71)favoring the nCRT,and renal failure(P=0.039;OR:1.04;95%CI:0.66-1.64)favoring the nCT.No significant differences were observed in terms of survival,local or distal recurrence,or other clinical or surgical complications.The result of RoB2 was moderate,and that of the GRADE approach was low or very low in almost all cases.CONCLUSION Although nCRT may have a higher pCR rate,it does not translate to greater long-term survival.Moreover,nCRT is associated with higher 30-d mortality,although the specific cause for postoperative complications could not be identified.In the case of nCT,toxic side effects are suspected,which can reduce the quality of life.Given the quality of available studies,further randomized trials are required.

Alterations in Serum Lipids and Lipoproteins Induced by Neoadjuvant Chemotherapy in Patients with Osteosarcoma around the Knee Joint:A Retrospective Analysis

Objective To investigate the serum lipid profiles of patients with localized osteosarcoma around the knee joint before and after neoadjuvant chemotherapy.Methods After retrospectively screening the data of 742 patients between January 2007 and July 2020,50 patients aged 13 to 39 years with Enneking stage II disease were included in the study.Serum lipid levels,including total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),lipoprotein-α[Lp(a)],and apolipoprotein A1,B,and E(ApoA1,ApoB,and ApoE),and clinicopathological characteristics were collected before and after neoadjuvant chemotherapy.Results The mean levels of TC,TG,and ApoB were significantly increased following neoadjuvant chemotherapy(16%,38%,and 20%,respectively,vs.pretreatment values;P<0.01).The mean levels of LDL-C and ApoE were also 19%and 16%higher,respectively(P<0.05).No correlation was found between the pretreatment lipid profile and the histologic response to chemotherapy.An increase in Lp(a)was strongly correlated with the Ki-67 index(R=0.31,P=0.023).Moreover,a trend toward longer disease-free survival(DFS)was observed in patients with decreased TG and increased LDL-C following chemotherapy,although this difference was not statistically significant(P=0.23 and P=0.24,respectively).Conclusion Significant elevations in serum lipids were observed after neoadjuvant chemotherapy in patients with localized osteosarcoma.There was no prognostic significance of pretreatment serum lipid levels on histologic response to neoadjuvant chemotherapy.The scale of increase in serum Lp(a)might have a potential prognostic role in osteosarcoma.Patients with increased LDL-C or reduced TG after chemotherapy seem to exhibit a trend toward favorable DFS.

Effectiveness of a theory-based tailored mHealth physical activity intervention for women undergoing chemotherapy for breast cancer:A quasi-experimental study

Objectives:This study aimed to explore the effectiveness of the theory-based tailored mHealth physical activity(PA)intervention among patients with breast cancer undergoing chemotherapy.Methods:A quasi-experimental study design was adopted.A total of 60 breast cancer patients were selected from two tertiary hospitals in Shanghai and Hangzhou City from September 2019 to August 2021.According to the admission order,30 patients werefirst included in the control group,followed by 30 patients in the intervention group.A smartphone application(app)named“Breast Care”was developed based on social cognitive theory,self-efficacy theory,and the theory of planned behavior.The app integrated various functions,including information browsing,PA monitoring and feedback,symptom reporting,and social interaction.Patients in the intervention group received three months of personalized online PA guidance in addition to routine care.The control group received routine care.Baseline and post-intervention investigations after three months were conducted in two groups using the Short Form of International Physical Activity Questionnaire,the Hospital Anxiety and Depression Scale,and the Functional Assessment of Cancer TherapydBreast cancer.Results:After three months of intervention,compared to the control group,breast cancer patients in the intervention group showed significant improvements in walking,moderate PA,and overall PA(P<0.05).Compared to the baseline data,breast cancer patients in the intervention group had significant improvements in walking and overall PA after three months(P<0.05),whereas the control group experienced significant declines in walking,moderate PA,and overall PA after three months(P<0.05).There were statistically differences between the two groups in scores for anxiety,overall quality of life,and its dimensions,such as physical well-being,emotional well-being,and additional breast cancer well-being(P<0.05).Conclusions:The theory-based tailored mHealth PA intervention has demonstrated a positive impact on promoting PA behavior change and emotional management among breast cancer patients.The‘Breast Care’app integrated various practical behavior change strategies,offering valuable guidance for personalized remote rehabilitation support for cancer patients.
