Pendahuluan. Salah satu terapi dari kanker paru jenis Non-Small Cell Lung Cancer (NSCLC) stadium lanjut adalah kemoterapi. Jenis kemoterapi yang sering digunakan di Indonesia adalah cisplatin- toposide dan cisplatin-docexatel. Tolak ukur keberhasilan pengobatan adalah kesintasan dan Progression Free Survival (PFS). Keberhasilan kemoterapi dipengaruhi oleh banyak faktor, seperti resistensi terhadap sitostatika, dosis, intensitas pemberian, jenis kemoterapi, jenis histologi, stadium, perfoma status, komorbiditas dan sosial ekonomi. Di Indonesia, pendanaan dan jenis rejimen kemoterapi masih merupakan masalah terhadap keberhasilan terapi.Metode. Penelitian menggunakan desain kohort retrospektif dengan analisis kesintasan. Pasien yang dimasukkan dalam penelitian ini adalah pasien kanker paru jenis NSC stadium lanjut (minimal stadium IIIa), yang datang ke Rumah Sakit Kanker Dharmais (RSKD) dan Rumah Sakit dr. Cipto Mangunkusumo (RSCM) Jakarta pada Januari 2006–Desember 2010 yang baru pertama kali dikemoterapi sampai selesai, sebanyak 6 kali dan dilakukan pengamatan 2 tahun. Data dianalisis dengan program SPSS 16.0 dan dilakukan analisis cox regression yang ditampilkan dalam kurva Kaplan Meier.Hasil. Didapatkan sebanyak 55 pasien menggunakan cisplatin-etoposide (EC) dan 55 pasien menggunakan cisplatindocexatel (DC). Terdapat perbedaan kesintasan 1 tahun EC sebesar 30,9% dan DC sebesar 47,3% dengan nilai p= 0,030. Sementara itu, pada kesintasan 2 tahun, juga terdapat perbedaan EC sebesar 0% dan DC sebesar 5,5%, dengan nilai p= 0,003, demikian juga median time survival antara EC selama 27 minggu dengan DC selama 38 minggu (p <0,016). Dibandingkan DC, kemoterapi EC dapat meningkatkan risiko kematian dengan HR 1,684 (IK95% 1,010-2,810). Selain itu,terdapat perbedaan PFS 24 minggu antara kemoterapi EC (54,5%) dan DC (32,7%) dengan nilai p= 0,022.Simpulan. Kesintasan cisplatin-docexatel lebih baik bila dibandingkan dengan cisplatin-etoposide, demikian juga dengan progression free survival.Kata Kunci: cisplatin-docexatel, cisplatin-etoposide, kesintasan, NSCLC, PFS Comparison of Chemotherapy Regiments between Cisplatin Etoposide and Cisplatin-Docetaxel on 2-Year and Progression-Free Survival in Late-Stage Non-Small Cell Lung Cancer PatientsIntroduction. Chemotherapy is one of therapy choices for the advanced Non-Small Cell Lung Cancer (NSCLC). The success in therapy is measured with the 1-year survival, 2-year survival and the Progression Free Survival (PFS). The success is influenced by many factors: resistant to the citostatic, dosage, administer intensity, chemotherapy regiment, type histology, stage, performance status, comorbidity and social economic. In Indonesia, funding and chemotherapy regiment become the challenge for the success of therapy.Methods. The study used the Retrospective Cohort study with survival analysis. The Patients included in this study were the advanced NSC Lung Cancer (At least Stadium IIIa) who came to RSKD and RSCM during Jan 2006 – December 2010 for their first chemotherapy until finished the cycle (6 times) and had monitored for 2 years. Data was analyzed using cox regression analysis SPSS 16.0, and featured on the Kaplan Meier Curve. Results. Fifty five patients used EC and the other 55 patients used DC. There’s difference on survival where 1 year survival EC is 30,9% and DC is 47,3%, with p 0.030. Two year survival CE is 0% and for DC is 5.5%, with p 0.003. Also with the Median time survival between EC for 27 weeks and DC for 38 weeks with p < 0.016. Compared to DC, EC chemotherapy can increase the death risk by HR 1,684 (CI 95% 1,010-2,810), twenty four weeks PFS with EC is 54.5%, DC is 32.7% with p= 0.022. Conclusions. The survival with cisplatin-docexatel is better compared to cisplatin-etoposide, this applies to PFS as well. Keywords: cisplatin docetaxel, cisplatin etoposide, NSCLC, PFS, Survival

Background: Cytidine deaminase (CDA) polymorphisms may affect the response to gemcitabine/cisplatin chemotherapy in patients with non-small cell lung cancer (NSCLC). This study is designed to investigate the associations of CDA-79A>C and 208G>A polymorphisms and gemcitabine/cisplatin chemotherapy effectiveness in Xinjiang Uyghur and Han patients. Methods: This prospective cohort study enrolled consecutive patients with stage IIIb/IV NSCLC administered gemcitabine/cisplatin chemotherapy at the First Affiliated Hospital, Medical College of Shihezi University and the First People’s Hospital, Kashgar Region. CDA-A79C and CDA-G208A polymorphisms were detected by direct sequencing. Progression-free survival was analyzed by the Kaplan-Meier method. Associations of A79C and G208A polymorphisms with treatment effectiveness and progression-free survival were analyzed using logistic regression and multivariate Cox regression analyses. Subgroup analyses based on ethnicity were performed. Results: The study enrolled 120 patients. A79C and G208A polymorphisms followed the Hardy-Weinberg equilibrium. The frequencies of the AA, AC, and CC genotypes and the A and C alleles of A79C were 52.2%, 29.9%, 17.9%, 67.2%, and 32.8%, respectively, in Han patients and 75.4%, 18.9%, 5.7%, 84.9%, and 5.1%, respectively, in Uyghur patients. Uyghur patients had lower frequencies of A79C-AC/CC genotypes, A79C-C allele, G208A-GA genotype, and G208A-A allele ( P<0.05). Compared with A79C-AA, the odds of ineffective chemotherapy were increased for A79C-AC (odds ratio [OR] 2.818; 95% confidence interval [95% CI] 1.031, 7.705; P=0.043) and A79C-CC (OR 9.864; 95% CI 1.232, 78.966; P=0.031). G208A polymorphisms did not influence chemotherapy effectiveness. Chemotherapy was more effective in Han patients than in Uyghur patients for A79C-AC and G208A-GG. Progression-free survival was longer for A79C-AA versus A79C-AC/CC (10 vs. 7 months, P=0.004) and G208A-GA/AA vs. G208A-AA (12 vs. 8 months, P=0.010). Polymorphisms of A79C (hazard ratio [HR] 1.617; 95% CI 1.009, 2.592; P=0.046) and G208A (HR 2.193; 95% CI 1.055, 4.557; P=0.035) were associated with progression-free survival. Conclusion: For Uyghur and Han ethnic groups, A79C and G208A polymorphisms can be used as a promising biomarker for the chemotherapy efficacy and prognosis of NSCLC.

Abstract BackgroundCheckpoint-inhibitor therapy (CPI) has significantly changed therapy in non-small cell lung cancer (NSCLC) in recent years. There is some data that the effect of CPI-therapy is influenced by the microbiome. Little is known about the influence and timing of antimicrobial therapy (AMT) on the microbiome mediated effect on CPI therapy.Patients and methodsWe retrospectively analysed 70 patients (age 68 ± 9,2y) with NSCLC stage IV. Patients were treated according to the guidelines with either CPI alone (pembrolizumab, nivolumab, atezolizumab) or chemotherapy (platin doublet or docetaxel / nintedanib or pemetrexed). We registered patients’ characteristics including presence and timing of AMT. Group 1 consisted of 27 patients with AMT in the month before CPI- or chemotherapy, group 2 were 30 patients with AMT during CPI- or chemotherapy, and group 3 were 43 patients without AMT.ResultsGroup 1–3 showed comparable patients characteristics. Using cox-regression analysis, we found that AMT in the month before CPI resulted in a decreased progression free survival (PFS) compared to patients with CPI and no AMT (14 ± 1.56 vs. 5 ± 0.99, p = 0.005, 95% CI: 0.13–0.67). In patients, who were treated with chemotherapy alone, there was no difference in PFS in those with or without AMT in the month before therapy (5+/- 0,99 vs. 6 ± 0.81 months, p = 0.3). Interestingly, AMT during chemotherapy or CPI therapy showed no effect on PFS.ConclusionsIn a real-life setting, we found that AMT reduces PFS when given in the month before CPI therapy. AMT before chemotherapy and during CPI and chemotherapy seems not to influence PFS. The best PFS was seen in patients without AMT before CPI therapy. This implies the need for an even more restrictive use of AMT in the context of patients with NSCLC stage IV disease.

Abstract Aim: Centrally located early-stage non-small cell lung cancer in patients who are unfit for surgery are treated with fractionated radiotherapy. We present the outcomes of a moderately hypofractionated accelerated dose regimen of 50 Gy in 15 fractions from a single centre in the UK. Materials and methods: Electronic case notes and radiotherapy records of lung cancer patients treated between January 2014 and December 2016 were retrospectively reviewed. Adult Comorbidity Evaluation-27 score was used to evaluate comorbidities. Mean lung doses and percentage of lung receiving more than 20 Gy were calculated for all patients. Survival outcomes were estimated using Kaplan–Meier curves. Results: Fifty-three patients were included in the study; the median follow-up was 20.2 months. 87% of patients had stage I disease. There was no 30-day post-treatment mortality. Ninety-day mortality rate after radiotherapy was 3.8%. Grade 2 pneumonitis was seen in five patients while no grade 3 or 4 pneumonitis was observed. The median progression-free survival (PFS) and overall survival (OS) were 18.5 months and 28.2 months, respectively. The estimated 1 and 2 years PFS were 62.3% and 41.3%, respectively, and OS were 77.4% and 56.6%, respectively. Worsening performance status was associated with worse survival on cox regression analysis. Disease relapsed in 36% of patients. 7.5% of patients with relapsed disease had infield recurrence. Findings: 50 Gy in 15 fractions radiotherapy for central early-stage lung cancer is a feasible choice that requires further randomised trials.

Background/Aim. About 1.8 million new lung cancer cases are diagnosed in the world every year, and about 1.6 million cases are with fatal outcome. Despite improvements in treatment in previous decades, the survival of patients with lung cancer is still poor. The five-year survival rate is about 50% for patients with localized disease, 20% for patients with regionally advanced disease, 2% for patients with metastatic disease, and about 14% for all stages. The median survival of patients with untreated NSCLC in the advanced stage is four to five months and the annual survival rate is only 10%. The main goal of the research is to obtain and analyze the results of treatment with concomitant chemotherapy in terms of its efficacy and toxicity in selected patients with locally advanced inoperable non-small cell lung cancer. Methods. The study included data analysis of 31 patients of both sexes who were diagnosed and pathohistologically verified with NSCLC in inoperable stage III and were referred by the Council for Malignant Lung Diseases to the Radiotherapy Department of the Military Medical Academy for concomitant chemoradiotherapy treatment. Upon expiry of the three-month period from the performed radiation treatment, the tumor resonance was assessed on the basis of MSCT examination of the chest and upper abdomen according to RECIST 1.1 criteria (Response Evaluation Criteria in Solid Tumors). According to the same criteria, progression-free survival (PFS) was also assessed every three months during the first two years, then every 6 months or until the onset of disease symptoms, as well as overall survival (OS). Result. The median progression-free survival is 13 months, and the median overall survival is 20 months. During and immediately after RT, 9 (29%) patients had a grade 2 or higher adverse event. Conclusion. The use of concomitant chemoradiotherapy in patients in the third stage of locally advanced inoperable non-small cell lung cancer provides a good opportunity for a favorable therapeutic outcome, with an acceptable degree of acute and late toxicity, and represents the standard therapeutic approach for selected patients in this stage of the disease.
