Effects of Aidi injection on vinorelbine plus cisplatin chemotherapy for advanced non-small cell lung cancer

Objective： To evaluate the effects of Aidi injection on vinorelbine plus cisplatin （NP） chemotherapy for advanced non-small cell lung cancer （NSCLC）. Methods： Ninety eight patients with advanced NSCLC were randomized to receive either NP alone or NP plus Aidi injection every 3 weeks. The primary endpoint was overall survival; secondary endpoints included overall response rate, time to progression, and safety. Results： The median overall survival time was 11.6 months in NP plus Aidi-treated patients and 10.1 months in NP alone-treated ones, and 1- and 2-year survival rates were higher in the former （47% and 22%） than the latter （42% and 15%）. The overall response rates in Aidi injection plus NP-treated patients tended to be higher but not statistically significant compared with NP alone-treated ones. The occurrence rates of grades 3 or 4 toxicities, e.g. fatigue, nausea, vomiting, appetite loss, leucopenia, thrombocytopenia and anemia, were lower in Aidi injec- tion plus NP-treated patients than NP alone-treated ones, although not significantly different between them. Con^lusion：Aidi injection promotes NP chemotherapeutic effects, reduces the toxicities, and improves the patients＇ tolerance to chemotherapy as well. It may be an effective adjunct to chemotherapy in patients with NSCLC.

Clinical Effect of Tislelizumab Combined with Chemotherapy in the Treatment of Stage IIIb-IV Non-Small Cell Lung Cancer

Objective:To analyze the therapeutic effect of tislelizumab combined with chemotherapy in patients with stage IIIb-IV non-small cell lung cancer(NSCLC).Methods:A total of 50 patients with stage IIIb-IV NSCLC admitted between January 2022 and January 2024 were randomly divided into two groups using a random number table.The observation group included 25 cases treated with tislelizumab combined with chemotherapy,while the reference group included 25 cases treated with conventional chemotherapy.The clinical control rate,adverse reaction rate,tumor markers,immune function indicators,and quality of life scores were compared between the two groups.Results:The observation group had a higher clinical control rate and a lower adverse reaction rate compared to the reference group(P<0.05).Before treatment,there were no significant differences in tumor markers,immune function indicators,and quality of life scores between the two groups(P>0.05).Three months after treatment,the tumor marker levels in the observation group were lower than those in the reference group.Except for CD8^(+),all immune function indicators in the observation group were higher than those in the reference group,and the quality-of-life scores in the observation group were higher than those in the reference group(P<0.05).Conclusion:Implementing tislelizumab combined with chemotherapy in patients with stage IIIb-IV NSCLC can improve the clinical control rate,reduce the adverse reaction rate,lower tumor marker levels,protect immune function,and improve quality of life.

CLINICAL EFFICACY OF VINORELBINE PLUS CISPLATIN IN ADVANCED NON-SMALL CELL LUNG CANCER

A clinical study of the efficacy of vinorelbine plus cisplatin regimen in the management of advanced NSCLC was performed in 35 patients. Five of the 35 patients failed to finish one cycle of chemotherapy with this regimen because of severe and intractable leukopenia or rapid progress of the disease. Tumor response and toxicity were evaluated in the remaining 30 cases. Results showed that, with this regimen, the objective response rate (CR+PR) was 46.7%. The most common toxicity was leukopenia; other side effects included alopecia, gastrointestinal reactions, slight and transient renal and hepatic impairment and peripheral neuropathy. It suggested that vinorelbine plus cisplatin is a safe and effective regimen in the management of advanced NSCLC.

Meta-analysis of efficacy and safety of Endostar combined with vinorelbine and cisplatin in the treatment of non-small cell lung cancer

Objective:To systematically evaluate the efficacy and safety of rh-endostain(YH-16,Endostar)combined with vinorelbine and cisplatin(NP regimen)in the treatment of non-small cell lung cancer(NSCLC),and to provide evidence-based reference for clinical drug use.Methods:Retrieved from PubMed,EMBASE,the Cochrane Library,Clinical Trials,CNKI,VIP and Wan Fang database,randomized controlled trials(RCT)about YH-16 combined with NP regimen(NPY regimen,trial group)vs.NP regimen(control group)for NSCLC were collected.After screening the literature and extracting the data,the two persons evaluated the quality of the included studies,and used Rev Man 5.3 software to merge effect size.Results:A total of 18 articles were included,with a total of 2051 patients.Results of Meta-analysis showed that response rate[RR=1.66,95%CI(1.44,1.91),P<0.00001]、clinical benefit rate[RR=1.21,95%CI(1.14,1.29),P<0.00001]and quality of life improvement rate[RR=3.42,95%CI(2.45,4.79),P<0.00001]of trial group were significantly higher than those of control group.Besides,the serum CEA level[MD=-4.78,95%CI(-7.11,-2.46),P<0.0001]and CA125 level[MD=-16.44,95%CI(-20.83,-12.05),P<0.00001]of trial group were significantly lower than that of control group.There was no statistical significance in the 1-year survival rate and the incidence of myelosuppression,cardiotoxicity,gastrointestinal reaction,damage to the kidneys and liver,and alopecia(P>0.05).Conclusion:Compared with NP regimen alone,NPY regimen can improve the efficacy and quality of life of NSCLC patients,reduce the level of tumor markers,and does not increase the occurrence of adverse reactions,and has good efficacy and safety.However,the existing evidence shows that NPY regimen has the same effect as NP regimen alone in improving the 1-year survival rate of patients.The above conclusions need to be confirmed by further studies.

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.

Shenfu injection plus vinorelbine for elderly patients with non-small cell lung cancer in promoting the quality of life: a randomized controlled clinical trial

Objective： The present study aimed to investigate the efficacy of Shenfu injection plus vinorelbine on the promotion of the quality of life （QOL） in elderly non-small cell lung cancer （NSCLC） patients. Methods： A randomized single blind trial method was used. Forty-six patients with stage IIIB-IV of HSCLC were randomly divided into experimental group and control group. In the experimental group, the patients were treated with 50 mL Shenfu injection from day 1 to 14, plus vinorelbine （NVB） 25 mg/m^2 on day 1 and 8. In the control group, the patients were only treated with NVB 25 mg/m^2 on day 1 and 8. After two cycle＇s of treatment, QOL, efficacy and toxicity were observed. Results： The QOL was enhanced in both experimental group and control group. However, the difference of KPS after treatment in the experimental group was markedly higher than in the control group （14 ± 10 vs. 8 ± 10, t = 2.116, P = 0.04）, improvement rate of QOL was better than in the control group （76.2% vs. 45.0%, χ^2 = 4.188, P = 0.041）, treatment related toxicity in the experimental group was also markedly lower than in the control group （χ^2 = 3.866, P = 0.049）, but the difference of efficacy between the two groups was not significant （14.3% vs. 15.0%, χ^2 = 0.161, P = 0.688）. Conclusion： Shenfu injection plus vinorelbine can enhance QOL in elderly NSCLC patients.

Prognostic Impact of Histopathologic Response after Neoadjuvant Chemotherapy in Stage Ⅲ_A Non-small Cell Lung Cancer

Objective： To investigate prognostic impact of histopathologic response induced by neoadjuvant chemotherapy in patients with stage ⅢA non-small cell lung cancer （NSCLC）. Methods： Forty patients with stage ⅢA NSCLC underwent two cycles of neoadjuvant chemotherapy with mitomycin, vindosine, and cisplatin followed by surgery. Histopathologic response in resection of the tumor was examined after surgery. Tumor regression was classified as grade Ⅳ, grade Ⅲ, grade Ⅱ, and grade Ⅰ according to the extent of tumor necrosis and the extent of the vital tumor tissues. The tumor regression grading was correlated with the survival time of the patients. Results： After two cycles of chemotherapy, 19 （47.5%） of 40 patients had objective response （2 complete and 17 partial response）. In 40 resected tumor specimens, 2 （5%） were classified as regression grade Ⅳ, 16 （40%） as regression grade Ⅲ, 18 （45%） as regression gradeⅡ, and 4 （10%） as regression grade Ⅰ. The rate of complete surgical resection was significantly higher in patients with tumor regression grade Ⅲ-Ⅳ （〈10% vital tumor tissue）（P〈0.05）. The median survival time in patients classified as having tumor regression grade Ⅲ-Ⅳ was significantly longer than that in patients who had regression grade Ⅰ-Ⅱ （P〈0.05）. The 3-year survival rate in patients with regression grade Ⅲ-Ⅳ was markedly higher than that in patients who had regression grade Ⅰ-Ⅱ （P〈0.05）. Conclusion： The extent of tumor regression induced by neoadjuvant chemotherapy is a critical issue for successful therapeutic approach in patients with stage ⅢA NSCLC. In resected specimens of tumors after chemotherapy, the presence of marked tumor regression （regression grade Ⅲ-Ⅳ） is predictive for superior survival time.

Effects of gemcitabine and cisplatin chemotherapy in advanced non-small cell lung cancer patients with RRM1 low protein expression

Objective： The aim of this study was to observe the efficacy of gemcitabine combined with cisplatin （GP） in advanced non-smaU cell lung cancer （NSCLC） patients with low expression of ribonucleotide reductase 1 （RRM1） protein using immunohistochemistry. Methods： RRM1 protein expression in tumor tissue was detected by streptavidin-peroxidase （SP） method of immunohistochemistry. GP regimen （gemcitabine 1000-1250 mg d1, d8, cisplatin 75 mg/m2） was given to advanced NSCLC patients with low expression of RRM1 protein. Results： In the total of 40 patients, these patients with RRM1 low expression performing GP chemotherapy had a good response rate, the objective response rate （ORR） was 47.5% （95% CI, 32.02%- 62.98%）, and the disease control rate （DCR） was 72.5% （95 % CI, 65.44%-79.56%）. ORR is 45.45% （5/11） in the squamous cell carcinoma patients while 48.15% （13/27） in the adenocarcinoma patients. Conclusion： Supedor ORR and DCR were found in advanced NSCLC patients with low expression of RRM1 protein expression performing GP regimen.

A radiomics prognostic scoring system for predicting progression-free survival in patients with stageⅣnon-small cell lung cancer treated with platinum-based chemotherapy

Objective:To develop and validate a radiomics prognostic scoring system(RPSS)for prediction of progressionfree survival(PFS)in patients with stageⅣnon-small cell lung cancer(NSCLC)treated with platinum-based chemotherapy.Methods:In this retrospective study,four independent cohorts of stageⅣNSCLC patients treated with platinum-based chemotherapy were included for model construction and validation(Discovery:n=159;Internal validation:n=156;External validation:n=81,Mutation validation:n=64).First,a total of 1,182 three-dimensional radiomics features were extracted from pre-treatment computed tomography(CT)images of each patient.Then,a radiomics signature was constructed using the least absolute shrinkage and selection operator method(LASSO)penalized Cox regression analysis.Finally,an individualized prognostic scoring system incorporating radiomics signature and clinicopathologic risk factors was proposed for PFS prediction.Results:The established radiomics signature consisting of 16 features showed good discrimination for classifying patients with high-risk and low-risk progression to chemotherapy in all cohorts(All P<0.05).On the multivariable analysis,independent factors for PFS were radiomics signature,performance status(PS),and N stage,which were all selected into construction of RPSS.The RPSS showed significant prognostic performance for predicting PFS in discovery[C-index:0.772,95%confidence interval(95%CI):0.765-0.779],internal validation(C-index:0.738,95%CI:0.730-0.746),external validation(C-index:0.750,95%CI:0.734-0.765),and mutation validation(Cindex:0.739,95%CI:0.720-0.758).Decision curve analysis revealed that RPSS significantly outperformed the clinicopathologic-based model in terms of clinical usefulness(All P<0.05).Conclusions:This study established a radiomics prognostic scoring system as RPSS that can be conveniently used to achieve individualized prediction of PFS probability for stageⅣNSCLC patients treated with platinumbased chemotherapy,which holds promise for guiding personalized pre-therapy of stageⅣNSCLC.

Clinical observation of Shenmai injection in the treatment for adverse reactions of chemotherapy on advanced non-small cell lung cancer

Objective: To observe the efficacy of Shenmai injection in the treatment for adverse reactions of chemotherapy on advanced non-small cell lung cancer (NSCLC). Methods: 45 NSCLC patients with stages IIIb-IV were randomly divided into two groups: the treatment group (treated by chemotherapy combined with Shenmai injection) and the control group (treated by chemotherapy only). The efficacy of the two groups was evaluated after 3 cycles of treatment. Results: There was no significant difference between the two groups in the recent curative effects (P > 0.05), while there were significant differences between them in Karnofsky score and weight (P < 0.05). The treatment group was better than the control group in preventing leucopenia and decreased hemoglobin, and significant differences were found between them (P < 0.05). The incidence of thrombocytopenia, nausea and vomiting, hepatic and renal dysfunction in the treatment group was lower than that in the control group, but no significant differences were found between them (P > 0.05). Conclusion: Shenmai injection would not influence the efficacy of chemotherapy on advanced NSCLC patients, while it could improve the quality of life, increase the body weight of patients, alleviate adverse reactions of chemotherapy as myelosuppression so as to improve the tolerance of organism to chemotherapy.

Better to be alone than in bad company:The antagonistic effect of cisplatin and crizotinib combination therapy in non-small cell lung cancer

AIM To investigate the potential benefit of combining the cMET inhibitor crizotinib and cisplatin we performed in vitro combination studies.METHODS We tested three different treatment schemes in four non-small cell lung cancer(NSCLC) cell lines with a different cMET/epidermal growth factor receptor genetic background by means of the sulforhodamine B assay and performed analysis with Calcusyn.RESULTS All treatment schemes showed an antagonistic effect in all cell lines,independent of the cMET status.Despite their different genetic backgrounds,all cell lines(EBC-1,HCC827,H1975 and LUDLU-1) showed antagonistic combination indexes ranging from 1.3-2.7.These results were independent of the treatment schedule.CONCLUSION These results discourage further efforts to combine cMET inhibition with cisplatin chemotherapy in NSCLC.

Continuous intravenous infusion of recombinant human endostatin using infusion pump plus chemotherapy in non-small cell lung cancer

BACKGROUND Lung cancer is one of the deadliest cancers in the world with the highest incidence and mortality rate among all cancers.Non-small cell lung cancer(NSCLC)accounts for approximately 80%of primary lung cancer.However,efficacy and safety of the current regimens for NSCLC is unsatisfactory.Therefore,there has been an increasing urgency for development of potential therapeutic therapies for NSCLC.AIM To investigate the therapeutic outcomes and safety of continuous intravenous infusion of recombinant human endostatin(Rh-endostain)using an infusion pump in retreated advanced NSCLC.METHODS Patients with retreated advanced NSCLC who were admitted to Zhejiang Provincial People's Hospital from October 2017 to April 2019 were recruited.These patients received continuous intravenous infusion of Rh-endostain using an infusion pump.Objective response rate(ORR),clinical benefit rate(CBR),median progression-free survival(mPFS),and incidences of adverse events(AEs)were analyzed after treatment.RESULTS A total of 45 patients with retreated advanced NSCLC were included,and all of them were evaluated.In these patients,ORR was 22.2%,CBR was 84.4%,and mPFS was 5.3 mo.The following AEs were observed,decreased hemoglobin(34 cases,75.6%),nausea/vomiting(32 cases,71.1%),elevated transaminase(24 cases,53.3%),leukopenia(16 cases,35.6%),thrombocytopenia(14 cases,31.1%),and constipation(1 case,3.4%).None of the patients had leukopenia,nausea/vomiting,and constipation of grade III and above.CONCLUSION The patients showed improved adherence to 5-d continuous intravenous infusion of Rh-endostain using an infusion pump.Favorable efficacy and safety of this treatment regimen were achieved in retreated advanced NSCLC.

Is there an optimal time to initiate adjuvant chemotherapy to predict benefit of survival in non-small cell lung cancer?

Objective: Adjuvant chemotherapy (AC) after curative resection is known to improve the survival of patients with non-small cell lung cancer (NSCLC); however, few studies have reported the correlation between the time to initiation of AC (TTAC) and survival in NSCLC patients. Methods: The clinical data of 925 NSCLC patients who received curative resection and post-operative AC at the Cancer Hospital of Chinese Academy of Medical Sciences between 2003 and 2013 were retrospectively analyzed. TTAC was measured from the date of surgery to the initiation of AC. Disease-free survival (DFS) was defined as the duration from surgery to the time of tumor recurrence or last follow-up evaluation. The optimal cut-off value of TTAC was determined by maximally selected log-rank statistics. The DFS curve was estimated using the Kaplan-Meier method, and the Cox proportional hazards regression model was used to identify risk factors independently associated with DFS. Propensity score matching (PSM) was performed for survival analysis using the match data. Results: The optimal discriminating cut-off value of TTAC was set at d 35 after curative resection based on which the patients were assigned into two groups: group A (<= 35 d) and group B (> 35 d). There was no significant difference in the DFS between the two groups (P=0.246), indicating that the TTAC is not an independent prognostic factor for DFS. A further comparison continued to show no significant difference in the DFS among 258 PSM pairs (P=0.283). Conclusions: There was no significant correlation between the TTAC and DFS in NSCLC patients. Studies with larger samples are needed to further verify this conclusion.

Effect of EGFR-TKI retreatment following chemotherapy for advanced non-small cell lung cancer patients who underwent EGFR-TKI

Objective： Non-small cell lung cancer （NSCLC） patients with epidermal growth factor receptor （EGFR）-activating mutations have higher response rate and more prolonged survival following treatment with single-agent EGFR tyrosine kinase inhibitor （EGFR-TKI） compared with patients with wild-type EGFR. However, all patients treated with reversible inhibitors develop acquired resistance over time. The mechanisms of resistance are complicated. The lack of established therapeutic options for patients after a failed EGFR-TKI treatment poses a great challenge to physicians in managing this group of lung cancer patients. This study evaluates the influence of EGFR-TKI retreatment following chemotherapy after failure of initial EGFR-TKI within at least 6 months on NSCLC patients. Methods： ＇i-he data of 27 patients who experienced treatment failure from their initial use of EGFR-TKI within at least 6 months were analyzed. After chemotherapy, the patients were retreated with EGFR-TKI （gefitinib 250 mg qd or erlotinib 150 mg qd）, and the tumor progression was observed. The patients were assessed for adverse events and response to therapy. Targeted tumor lesions were assessed with CT scan. Results： Of the 27 patients who received EGFR-TKI retreatment~ 1 （3.7%） patient was observed in complete response （CR）, 8 （29.6%） patients in partial response （PR）, 14 （51.9%） patients in stable disease （SD）, and 4 （14.8%） patients in progressive disease （PD）. The disease control rate （DCR） was 85.2% （95% CI： 62%-94%）. The median progression-free survival （mPFS） was 6 months （95% CI： 1-29）. Of the 13 patients who received the same EGFR-TKI, 1 patient in CR, 3 patients in PR, 8 patients in SD, and 2 patients in PD were observed. The DCRwas 84.6%, and the mPFS was 5 months. Of the 14 patients who received another EGFR-TKI, no patient in CR~ 6 patients in PR, 6 patients in SD, and 2 patients in PD were observed. The DCRwas 85.7%, and the mPFS was 9.5 months. Significant difference was found between the two groups in PFS but not in response rate or D CR. Conclusion： Retreatment of EGFR-TKIs can be considered an option after failure of chemotherapy for patients who were previously controlled by EGFR-TKI treatment.

Comparison of efficacy and toxicity between gemcitabine plus cisplatin and plus carboplatin in first-line treatment of advanced non-small cell lung cancer

Objective: To compare the efficacy and toxicity between gemcitabine plus cisplatin and plus carboplatin in first-line treatment of advanced non-small cell lung cancer (NSCLC). Methods: Gemcitabine 1000 mg/m2 iv, d1, 8; cisplatin 75 mg/m2 iv, d1, or 25 mg/m2 iv, d1-3; carboplatin AUC = 5 iv, d1; repeated every 21 days. Results: All 76 cases were available for objective response. Gemcitabine + cisplatin (GCis) group: among 33 cases, CR 1 case, PR 13 cases, MR 3 cases, SD 7 cases, PD 9 cases, response rate, disease control rate, time to progress (TTP), median survival time (MST) and 1-, 2-year survival rates were 42.42% (14/33), 72.73% (24/33), 5 months, 14 months and 66.67% (22/33), 12.12% (4/33), respectively; Gemcitabine + carboplatin (GCarb) group: among 43 cases, PR 13 cases, MR 11 cases, SD 7 cases, PD 12 cases, the results while comparing with those of GCis group were 30.23% (13/43), 72.09% (31/43), 4 months, 11 months and 48.84% (21/43), 2.33% (1/43), respectively. Among them, only MST between the two groups had significant statistic difference (χ2 = 2.45, P = 0.017). Mild to modest myelo-suppression as well as nausea and vomiting were observed. Conclusion: Both GCis and GCarb regimens had active and well-tolerated toxicity for advanced NSCLC. Cisplatin-based chemotherapy yields a substantial effective advantage over carboplatin-based regimens. Therefore, carboplatin and cisplatin are not equal-active and that cisplatin-based doublet regimens should remain the standard first-line therapy for patients with advanced NSCLC with good performance status.

Docetaxel as salvage chemotherapy in patients with advanced non-small cell lung cancer after failure of cytotoxic agents and gefitinib treatment

Objective： We conducted a prospective phase II trial of single-agent salvage chemotherapy with docetaxel in patients with advanced non-small cell lung cancer （NSCLC） after failure of chemotherapy and gefitinib to assess the efficacy and toxicity of docetaxel in this setting. Methods： Patients with histologically confirmed NSCLC who were failure of chemotherapy and gefitinib were given docetaxel 75 mg/m^2 intravenously for 30 rain every 3 weeks until the toxicity was unacceptable or disease progressed. The response evaluation criteria in solid tumors （RECIST） guidelines were used for the evaluation of an- titumor activity. Toxicity was graded according to the National Cancer Institute Common Toxicity Criteria version 2.0. Results： In total, 31 patients were enrolled in this phase II trial between February 2004 and December 2006, and 84 cycles （average 2.7 cycles） were given. We observed 4 partial responses （PRs） and 10 stable disease （SD） states in 31 eligible patients. The objective response rate was 12.9%, and the disease control rate was 45.2%. The median survival time （MST） was 10 months （95% CI, 5.05-15.08 months）. The 1-year survival rate was 40.6%. The most common toxicities were neutropenia, anemia, and peripheral neuropathy that occurred as follows： 45% of the patients experienced grade 3 or 4 neutropenia, 29% experienced grade 3 anemia, and 25.8% had grade 3 peripheral neuropathy. No patient terminated docetaxel chemotherapy due to toxicity. Conclusion： Docetaxel is beneficial as salvage chemotherapy in patients with advanced NSCLC after failure of cytotoxic agents and gefitinib.

Outcomes of Quality of Life Regarding the Next-Generation Thoracoscopic Intrapleural Hyperthermic Chemotherapy of Non-Small Cell Lung Cancer with Dissemination

Background: We have developed a new next-generation intrapleural hyperthermic chemotherapy (IPHC) for non-small cell lung cancer with dissemination, which is a hybrid chemotherapy combined with oral S-1 medication plus conventional cisplatin-based IPHC. We now report the preliminary feasibility and outcome of quality of life (QOL) regarding this hybrid IPHC. Methods: The patient was a 76-year-old male with a 2-cm nodule in the left upper lobe. After partial resection by video-assisted thoracic surgery (VATS), which was diagnosed with advanced pulmonary adenocarcinoma with intrapleural dissemination. We initially performed two regimens of systemic chemotherapy, S-1 (day 1 - 21, 100 mg 2X/day) + CDDP (day 8, 60 mg/m2) and S-1 (day 1 - 14,100 mg 2X/day) + CBDCA (day 1, AUC 5). The regimen of next-generation IPHC is oral S-1 medication (day 1 - 21, 100 mg/day) + intrapleural hyperthermic perfusion of cisplatin (200 mg/m2) with VATS (day 8,43°C, 2 hours). Adverse outcomes, QOL, and pleural effusion were assessed in three regimens. To investigate the outcomes of the QOL, the European Organization for Research and Treatment of Cancer QOL Questionnaire (EORTC QLQ-C30 and QLQ-LC13), the QOL questionnaire for cancer patients treated with anticancer drugs (QOL-ACD), the Cancer Dyspnea Score (CDS), and the St. George’s Respiratory Questionnaire (SGRQ) were used. Results: During the IPHC treatment course, grade 3 neutropenia, anemia, and diarrhea were observed. The physical function after IPHC became worse compared to that before the IPHC. Fatigue during chemotherapy (CBDCA+S-1) was more pronounced than that during the IPHC. Nausea, vomiting, and diarrhea during the IPHC were prevalent than those of chemotherapy. The overall QOL after the IPHC was improved compared to that before the IPHC. Regarding before and after the IPHC, the physical function after the IPHC became worse compared to that before the IPHC, on the other hand, the global QOL before and after the IPHC had not dramatically changed. Pleural effusion was controlled after the IPHC for more than 1 year. Conclusion: The first case of a clinical trial of the next-generation IPHC showed grade 3 adverse events. However, it was an acceptable feasibility compared to the usual platinum doublet chemotherapy. The effectiveness of the IPHC allowed the patient to obtain a good control of the pleural effusion and preserved the patient’s QOL.

Concurrent gemcitabine and cisplatin combined with 3D conformal radiotherapy for stage III non-small cell lung cancer

Objective： To study the toxicities and efficacy of concurrent gemcitabine plus cisplatin combined with three-dimensional conformal radiotherapy for stage Ⅲ non-small cell lung cancer （NSCLC）. Methods： Thirty-six patients with pathologically diagnosed NSCLC received radiotherapy and concurrent chemotherapy. There were 22 patients with stage Ilia and 14 patients with IIIb. Radiotherapy was given a total of 60-70 Gy in conventional fractionation. Chemotherapy included gemcitabine （600 mg/m^2） and cisplatin （20 mg/m^2）, once per week. Results： Thirty-two patients received a total dose of 60-72 Gy. Two patients received 56 Gy and another two patients received 58 Gy. Thirty-four patients received 4-6 weeks of chemotherapy, while two patients received only 2 weeks of chemotherapy. The overall response rate （CR ＋ PR）, complete response rate （CR）, partially response rate （PR） were 83.3% （30/36）, 11.1% （4/36） and 72.2% （26/36） respectively. The median follow-up duration was 18.4 months. The 1- and 2-year overall survival rates were 77.8% （28/36） and 55.6% （20/36）, respectively. Conclusion： Concurrent gemcitabine and cisplatin combined with three-dimensional conformal radiotherapy for stage III non-small cell lung cancer is effective and well tolerated. Lone-term results need further study.

Adjuvant Chemotherapy of Gemcitabine plus Carboplatin versus Paclitaxel plus Carboplatin in Patients with Resected Non-Small Cell Lung Cancer

Background: This retrospective study was to evaluate the efficacy and toxicity of gemcitabine plus carboplatin (GC regimen) and paclitaxel plus carboplatin (PC regimen) combination chemotherapy administered as an adjuvant therapy after complete resection of non-small cell lung cancer. Methods: Forty-four patients (GC regimen, n = 29;PC regimen, n = 15) received gemcitabine at a dose of 1000 mg/m2 on days 1 and 8, and carboplatin with the target dose of area under the curve (AUC) of 4 on day 8 every 28 days and paclitaxel at a dose of 70 mg/m2 on days 1, 8 and 15, and carboplatin with the target dose of AUC of 5 on day 1 every 28 days. Results: A total of 130 cycles of the treatment were administered (averaged, 3.1 in GC arm and 2.7 cycles in PC arm). Forty-three patients (97.7%) completed the scheduled cycles. One patient (2.3%) was discontinued due to grade 4 pneumonia. The dose was reduced in 2 patients (4.5%) due to grade 4 thrombocytopenia. Grade 3/4 neutropenia was significantly observed in the PC group (GC: 12/29, 41.4%;PC: 11/15, 73.3%, p = 0.0443). The nonhematological toxicities were mild. Grade 1/2 alanine aminotransferase and aspartate aminotransferase in the GC group was significantly observed higher compared to those of the PC group (GC: 20/29, 69.0%;PC: 4/15, 26.7%, p = 0.0076). Grade 1/2 alopecia was significantly observed in the PC group (GC: 0/25, 0.0%;PC: 13/15, 86.7%, p 0.0001). There was no treatment-related death. The median survival time (MST) of the entire GC group was 784 days, the 3-year overall survival (OS) was 75.9%, and 3-year recurrence-free survival (RFS) was 65.5%. The MST of the entire PC group was 963 days, the 3-year OS was 80.0%, and the 3-year RFS was 60.0%. Conclusion: These results demonstrate that the GC and PC combination chemotherapies are efficacious and feasible regimens, which should be considered as one of the standard therapies for adjuvant therapy.
