RESUMEN
BACKGROUND: This post-hoc retrospective study describes long-term patient-reported outcomes (PROs) for REarranged during Transfection (RET)-altered non-small-cell lung cancer (NSCLC), medullary thyroid cancer (MTC), non-MTC thyroid cancer (TC), and tumor agnostic (TA) patients (Data cut-off: January 2023) from the LIBRETTO-001 trial. PATIENTS AND METHODS: Patients completed the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30). Patients with MTC also completed a modified version of the Systemic Therapy-Induced Diarrhea Assessment Tool (mSTIDAT). The proportion of patients with improved, stable, or worsened status after baseline was reported. PROs were summarized at 3 years (cycle 37) post-baseline for the NSCLC and MTC cohorts, and at 2 years (cycle 25) post-baseline for the TC and TA cohorts. Time-to-event outcomes (time to first improvement or worsening and duration of improvement) were reported. RESULTS: The baseline assessment was completed by 200 (63.3%), 209 (70.8%), 50 (76.9%), and 38 (73.1%) patients in the NSCLC, MTC, TC, and TA cohorts, respectively. The total compliance rate was 80%, 82%, 70%, and 85%, respectively. Approximately 75% (NSCLC), 81% (MTC), 75% (TC), and 40% (TA) of patients across all cohorts reported improved or stable QLQ-C30 scores at year 3 (NSCLC and MTC) or year 2 (TC and TA) with continuous selpercatinib use. Across cohorts, the median time to first improvement ranged from 2.0 to 19.4 months, the median duration of improvement ranged from 1.9 to 28.2 months, and the median time to first worsening ranged from 5.6 to 44.2 months. The total compliance rate for the mSTIDAT was 83.7% and the proportion of patients with MTC who reported diarrhea on the mSTIDAT was reduced from 80.8% at baseline to 35.6% at year 3. CONCLUSIONS: A majority of patients with RET-driven cancers improved or remained stable on most QLQ-C30 domains, demonstrating favorable health-related quality of life as measured by the QLQ-C30 during long-term treatment with selpercatinib.

BACKGROUND: Efficacy of necitumumab [recombinant human monoclonal antibody that blocks the ligand binding epidermal growth factor receptor (EGFR)] in patients with squamous (SQ) non-small-cell lung cancer (NSCLC) has been confirmed in two randomized clinical trials (SQUIRE and JFCM). This study evaluated the association between efficacy and initial skin toxicity with necitumumab treatment by analyzing pooled data from two clinical trials (SQUIRE and JFCM). MATERIALS AND METHODS: Data of 635 patients with SQ-NSCLC (intent-to-treat population) treated with necitumumab plus gemcitabine and cisplatin (N + GC) were pooled from two clinical trials (SQUIRE and JFCM). The relationship between skin toxicities developed by the end of the second cycle and efficacy was evaluated. Efficacy endpoints included overall survival (OS), progression-free survival (PFS), and objective response rate (ORR). Univariate and multivariate analyses were carried out for these endpoints. RESULTS: OS and ORR were associated with skin toxicity, whereas PFS was not. Patients with grade ≥2 or grade 1 skin toxicity had significantly longer OS compared to patients without skin toxicity (grade 0) in the N + GC group [median = 15.0 (grade ≥2); 12.7 (grade 1); 9.4 (grade 0) months; hazard ratio (HR) = 0.51 (grade ≥2 to grade 0); 95% confidence interval (CI) 0.40-0.64, P < 0.001 and HR = 0.64 (grade 1 to grade 0); 95% CI 0.52-0.80, P < 0.001]. In multivariate analysis, OS was significantly associated with skin toxicity. CONCLUSIONS: A significant association was found between necitumumab-induced skin toxicity and efficacy. These results are consistent with the previously reported association between other EGFR inhibitors-induced skin toxicity and efficacy.

BACKGROUND: Leptomeningeal metastases (LM) are devastating complications of epidermal growth factor receptor (EGFR)-mutated non-small-cell lung cancer (NSCLC). Although osimertinib, a third-generation EGFR-tyrosine kinase inhibitor (TKI), has better penetration into the central nervous system than first-generation EGFR-TKIs, data on the distinct activity of EGFR-TKIs in untreated advanced EGFR-mutated NSCLC with LM are lacking. PATIENTS AND METHODS: We retrospectively reviewed patients treated with EGFR-TKIs for TKI-untreated common EGFR-mutated NSCLC with LM between July 2002 and July 2021 at the National Cancer Center Hospital. The patients were divided into two groups: patients treated with osimertinib (Osi group) and those treated with gefitinib or erlotinib [first-generation (1G)-TKI group]. RESULTS: Of the 967 patients, 71 were eligible, including 29 in the Osi group and 42 in the 1G-TKI group. The median progression-free survival (PFS) and overall survival (OS) in the Osi group were better than those in the 1G-TKI group (PFS: 16.9 months versus 8.6 months, P = 0.007, and OS: 26.6 months versus 20.0 months, P = 0.158). The LM-overall response rate (ORR) and LM-PFS were significantly better in the Osi group than in the 1G-TKI group (LM-ORR: 62.5% versus 25.7%, P = 0.007; LM-PFS: 23.4 months versus 12.1 months, P = 0.021). In the subgroup analysis of EGFR mutation status, LM-PFS for patients with exon 19 deletion was significantly longer in the Osi group than in the 1G-TKI group (32.7 months versus 13.4 months, P = 0.013), whereas those with L858R mutation in exon 21 did not differ between the two groups. In the multivariate analysis, osimertinib and exon 19 deletion were significant factors for better LM-PFS and OS. CONCLUSION: Osimertinib can be more effective for untreated common EGFR-mutated NSCLC patients with LM, especially those with exon 19 deletion, compared to first-generation TKIs.

BACKGROUND: First-line nivolumab plus ipilimumab prolongs survival versus chemotherapy in advanced non-small-cell lung cancer (NSCLC). We further characterized clinical benefit with this regimen in a large pooled patient population and assessed the effect of response on survival. PATIENTS AND METHODS: Data were pooled from four studies of first-line nivolumab plus ipilimumab in advanced NSCLC (CheckMate 227 Part 1, 817 cohort A, 568 Part 1, and 012). Overall survival (OS), progression-free survival (PFS), objective response rate, duration of response, and safety were assessed. Landmark analyses of OS by response status at 6 months and by tumor burden reduction in responders to nivolumab plus ipilimumab were also assessed. RESULTS: In the pooled population (N = 1332) with a minimum follow-up of 29.1-58.9 months, median OS was 18.6 months, with a 3-year OS rate of 35%; median PFS was 5.4 months (3-year PFS rate, 17%). Objective response rate was 36%; median duration of response was 23.7 months, with 38% of responders having an ongoing response at 3 years. In patients with tumor programmed death-ligand 1 (PD-L1) <1%, ≥1%, 1%-49%, or ≥50%, 3-year OS rates were 30%, 38%, 30%, and 48%. Three-year OS rates were 30% and 38% in patients with squamous or non-squamous histology. Efficacy outcomes in patients aged ≥75 years were similar to the overall pooled population (median OS, 20.1 months; 3-year OS rate, 34%). In the pooled population, responders to nivolumab plus ipilimumab at 6 months had longer post-landmark OS than those with stable or progressive disease; 3-year OS rates were 66%, 22%, and 14%, respectively. Greater depth of response was associated with prolonged survival; in patients with tumor burden reduction ≥80%, 50% to <80%, or 30% to <50%, 3-year OS rates were 85%, 72%, and 44%, respectively. No new safety signals were identified in the pooled population. CONCLUSION: Long-term survival benefit and durable response with nivolumab plus ipilimumab in this large patient population further support this first-line treatment option for advanced NSCLC.

BACKGROUND: Nivolumab plus ipilimumab demonstrated clinically meaningful improvement in efficacy versus chemotherapy with a manageable safety profile in patients with advanced non-small cell lung cancer (NSCLC) and tumor programmed death-ligand 1 (PD-L1) expression ≥1% or <1% in Part 1 of CheckMate 227. Here we report efficacy and safety results for the Asian subpopulation. METHODS: Patients with stage IV/recurrent NSCLC were randomized 1 : 1 : 1 to nivolumab plus ipilimumab, nivolumab monotherapy, or chemotherapy (PD-L1 ≥1%) or nivolumab plus ipilimumab, nivolumab plus chemotherapy, or chemotherapy (PD-L1 <1%). Overall survival (OS), progression-free survival, objective response rate, duration of response, and safety were evaluated among patients in Japan, South Korea, and Taiwan. RESULTS: In the Asian subpopulation with PD-L1 ≥1%, 81 patients received nivolumab plus ipilimumab and 81 received chemotherapy. Median OS was not reached with nivolumab plus ipilimumab versus 24.8 months with chemotherapy; 3-year OS rate was 53% versus 37% [hazard ratio (HR), 0.72; 95% confidence interval (CI) 0.47-1.11]. The 3-year progression-free survival rate was 26% versus 7% (HR, 0.65; 95% CI 0.45-0.96), objective response rate was 56% versus 37%, and median duration of response was 29.0 months (95% CI 15.0 months-not reached) versus 6.9 months (95% CI 3.9-11.1 months). Similar results were observed regardless of tumor PD-L1 expression and in Japanese patients. Grade 3-4 treatment-related adverse events occurred in 40% of patients receiving nivolumab plus ipilimumab and 36% receiving chemotherapy, in the overall Asian subpopulation (tumor PD-L1 expression ≥1% and <1%); no new safety signals were identified. CONCLUSIONS: At 3-year follow-up, nivolumab plus ipilimumab provided durable long-term efficacy benefits versus chemotherapy regardless of tumor PD-L1 expression in the Asian subpopulation, including Japanese patients. Consistent with findings for all randomized patients, these data support the use of nivolumab plus ipilimumab as first-line treatment of Asian patients with advanced NSCLC.

BACKGROUND: This international, randomized, double-blind phase III study (ONO-4538-52/TASUKI-52) evaluated nivolumab with bevacizumab and cytotoxic chemotherapy as first-line treatment for nonsquamous non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Between June 2017 and July 2019, this study enrolled treatment-naïve patients with stage IIIB/IV or recurrent nonsquamous NSCLC without sensitizing EGFR, ALK, or ROS1 alterations. They were randomly assigned in a 1 : 1 ratio to receive nivolumab or placebo in combination with carboplatin, paclitaxel, and bevacizumab every 3 weeks for up to six cycles, followed by nivolumab/placebo with bevacizumab until progressive disease or unacceptable toxicity. The primary endpoint was progression-free survival (PFS) assessed by an independent radiology review committee (IRRC). RESULTS: Overall, 550 patients from Japan, Korea, and Taiwan were randomized; of these patients, 273 and 275 received the nivolumab and placebo combinations, respectively. In the present preplanned interim analysis with a median follow up of 13.7 months, the IRRC-assessed median PFS was significantly longer in the nivolumab arm than in the placebo arm (12.1 versus 8.1 months; hazard ratio 0.56; 96.4% confidence interval 0.43-0.71; P < 0.0001). The PFS benefit was observed across all patients with any programmed death-ligand 1 (PD-L1) expression levels including PD-L1-negative patients. The IRRC-assessed objective response rates were 61.5% and 50.5% in the nivolumab and placebo arms, respectively. The incidence of treatment-related adverse events of grade 3 or 4 was comparable between the two arms; treatment-related adverse events leading to death were observed in five and four patients in the nivolumab and placebo arms, respectively. CONCLUSION: The TASUKI-52 regimen should be considered a viable new treatment strategy for treatment-naïve patients with advanced nonsquamous NSCLC.

Hematological toxicities induced by pemetrexed plus platinum therapy remain a critical issue in clinical practice. We hypothesized that inhibition of the renin-angiotensin system (RAS) can ameliorate pemetrexed-induced hematological toxicities through drug-drug interactions involving organic anion transporters. Thus, this study aimed to clarify whether RAS inhibitors (RASIs) could prevent pemetrexed plus platinum-induced hematological toxicities. We retrospectively analyzed data from 305 consecutive patients with non-small cell lung cancer or malignant pleural mesothelioma who received their first cycle of a pemetrexed plus platinum regimen and were treated with or without RASIs. The primary endpoint was the incidence of severe myelosuppression after the first cycle. Propensity score (PS)-matched, PS-adjusted, and inverse probability of treatment weighting (IPTW) analyses were used. The number of patients with grade ≥3 hematological toxicities was 27 (8.9%). PS-matched analyses revealed that the concomitant use of RASIs was slightly associated with a lower risk of grade ≥3 hematological toxicities (odds ratio [OR], 0.68; 95% confidence interval [CI], 0.20-2.32; p = 0.536). Additionally, sensitivity analyses using PS-adjusted and IPTW methods demonstrated similar results (OR, 0.63; 95% CI, 0.19-2.15; p = 0.463 and OR, 0.37; 95% CI, 0.11-1.29; p = 0.117, respectively). These findings suggest that RASIs might prevent pemetrexed plus platinum-induced hematological toxicities.

BACKGROUND: Osimertinib is a potent, third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI). The multi-arm phase Ib TATTON study (NCT02143466) was designed to assess the safety and tolerability of osimertinib in combination with other targeted therapies: selumetinib (MEK1/2 inhibitor), savolitinib (MET-TKI), or durvalumab [anti-programmed cell death ligand 1 (anti-PD-L1) monoclonal antibody]. PATIENTS AND METHODS: Patients with advanced EGFR-mutant non-small-cell lung cancer and disease progression on a prior EGFR-TKI were enrolled and allocated to dose-escalating cohorts combining osimertinib 80 mg orally (p.o.) once a day with selumetinib (25-75 mg p.o. twice a day; continuous or intermittent), savolitinib (600-800 mg p.o. once a day), or durvalumab (3-10 mg/kg intravenous every 2 weeks). RESULTS: At data cut-off (28 February 2018), 77 patients were enrolled and received osimertinib plus selumetinib (n = 36), savolitinib (n = 18), or durvalumab (n = 23). Most common adverse events (any grade), occurring in ≥20% of patients across dose groups, were: selumetinib arm-diarrhea (75%), rash (58%), nausea (47%); savolitinib arm-nausea (67%), rash (56%), vomiting (50%); durvalumab arm-rash (48%), vomiting (43%), diarrhea (39%). Dose-limiting toxicities were reported in the selumetinib 25 mg (n = 1), 50 mg (n = 1), and 75 mg (n = 4) continuous-dose groups, savolitinib 600 mg (n = 1) and 800 mg dose groups (n = 2), and durvalumab 10 mg/kg (n = 1) dose group. The objective response rate was 42% (95% confidence interval 26% to 59%), 44% (22% to 69%), and 43% (23% to 66%) in the selumetinib, savolitinib, and durvalumab arms, respectively. CONCLUSION: Our results demonstrate the feasibility of combining osimertinib 80 mg with selumetinib or savolitinib at identified tolerable, active doses. A combination of osimertinib with durvalumab was not feasible due to increased reporting of interstitial lung disease. Osimertinib-based combination therapies represent a compelling approach now being further investigated. CLINICAL TRIALS NUMBER: NCT02143466.

BACKGROUND: Anaplastic lymphoma kinase (ALK) fusions need to be accurately and efficiently detected for ALK inhibitor therapy. Fluorescence in situ hybridization (FISH) remains the reference test. Although increasing data are supporting that ALK immunohistochemistry (IHC) is highly concordant with FISH, IHC screening needed to be clinically and prospectively validated. PATIENTS AND METHODS: In the AF-001JP trial for alectinib, 436 patients were screened for ALK fusions through IHC (n = 384) confirmed with FISH (n = 181), multiplex RT-PCR (n = 68), or both (n = 16). IHC results were scored with iScore. RESULT: ALK fusion was positive in 137 patients and negative in 250 patients. Since the presence of cancer cells in the samples for RT-PCR was not confirmed, ALK fusion negativity could not be ascertained in 49 patients. IHC interpreted with iScore showed a 99.4% (173/174) concordance with FISH. All 41 patients who had iScore 3 and were enrolled in phase II showed at least 30% tumor reduction with 92.7% overall response rate. Two IHC-positive patients with an atypical FISH pattern responded to ALK inhibitor therapy. The reduction rate was not correlated with IHC staining intensity. CONCLUSIONS: Our study showed (i) that when sufficiently sensitive and appropriately interpreted, IHC can be a stand-alone diagnostic for ALK inhibitor therapies; (ii) that when atypical FISH patterns are accompanied by IHC positivity, the patients should be considered as candidates for ALK inhibitor therapies, and (iii) that the expression level of ALK fusion is not related to the level of response to ALK inhibitors and is thus not required for patient selection.

BACKGROUND: We conducted a feasibility study of induction chemotherapy followed by gefitinib and thoracic radiotherapy (TRT) for unresectable locally advanced adenocarcinoma of the lung. PATIENTS AND METHODS: Patients received induction chemotherapy with cisplatin (80 mg/m(2), days 1 and 22) and vinorelbine (25 mg/m(2), days 1, 8, 22, and 29) followed by gefitinib (250 mg daily, beginning on day 43, for 1 year) and TRT (60 Gy/30 fractions, days 57-98). The primary end point was feasibility, which was defined as the proportion of patients who completed 60 Gy of TRT and received >75% of the planned dose of gefitinib without developing grade 2 or worse pneumonitis. RESULTS: Of the 38 enrolled patients, 23 patients [60.5% ; 80% confidence interval (CI) 48.8-71.3] completed treatment without experiencing grade 2 or worse pneumonitis. During the chemoradiation phase, grade 3-4 alanine aminotransferase elevations were observed in 37.1% of the patients. The overall response rate was 73.0% . The median survival time was 28.5 months (95% CI 22.5-38.2), and the 2-year survival rate was 65.4% . CONCLUSIONS: Although the results did not meet our criterion for feasibility, the toxicity was acceptable. This treatment warrants further evaluation among patients with locally advanced non-small-cell lung cancer harboring epidermal growth factor receptor mutations.

BACKGROUND: The treatment of squamous cell carcinoma of the lung has not advanced sufficiently. Nedaplatin is a second-generation platinum compound that is active against squamous cell carcinoma of the lung, with a response rate of ~40%. PATIENTS AND METHODS: Eligible patients with advanced squamous cell carcinoma of the lung were treated with docetaxel (60 mg/m(2)) and nedaplatin (100 mg/m(2)) administered i.v. on day 1; these doses were determined in an earlier phase I study. The treatment cycles were repeated every 3 weeks. The primary end point was the response rate, and the secondary end points were overall survival, progression-free survival, and toxicity. RESULTS: Twenty-one patients were enrolled. Eighteen of the patients were male, and the median age was 67 years. The objective response rate was 62%. The median progression-free survival time was 7.4 months. The median survival time was 16.1 months, and the 1-year survival rate was 66.7% (95% confidence interval 46.5% to 86.8%). The most common adverse event was neutropenia (grade 3/4, 86%). Non-hematological toxic effects were relatively mild. One patient died of sepsis. CONCLUSIONS: Combination chemotherapy with nedaplatin and docetaxel is highly active and has an acceptable toxicity. Further investigation of nedaplatin and docetaxel is warranted.

There are inadequate data on the outcomes of patients who declined to participate in randomised clinical trials as compared with those of participants. We retrospectively reviewed the patient characteristics and treatment outcomes of both participants and non-participants in the two randomised trials for chemotherapy-naive advanced non-small-cell lung cancer. Trial 1 compared four platinum-based combination regimens. Trial 2 compared two sequences of carboplatin plus paclitaxel and gefitinib therapies. Nineteen of 119 (16%) and 153 (37%) patients declined to participate in Trials 1 and 2, respectively. Among the background patient characteristics, the only variable associated with trial participation or declining was the patients' attending physicians (P<0.001). Important differences were not observed in the clinical outcomes between participants and non-participants, for whom the response rates were 30.6 vs 34.2% and the median survival times were 489 vs 461 days, respectively. The hazard ratio for overall survival, adjusted for other confounding variables, was 0.965 (95% confidence interval: 0.73-1.28). In conclusion, there was no evidence to suggest any difference in the characteristics and clinical outcomes between participants and non-participants. Trial designs and the doctor-patient relationship may have an impact on the patient accrual to randomised trials.

BACKGROUND: To compare the efficacy and toxicity of three platinum-based combination regimens against cisplatin plus irinotecan (IP) in patients with untreated advanced non-small-cell lung cancer (NSCLC) by a non-inferiority design. PATIENTS AND METHODS: A total of 602 patients were randomly assigned to one of four regimens: cisplatin 80 mg/m(2) on day 1 plus irinotecan 60 mg/m(2) on days 1, 8, 15 every 4 weeks (IP) carboplatin AUC 6.0 min x mg/mL (area under the concentration-time curve) on day 1 plus paclitaxel 200 mg/m(2) on day 1 every 3 weeks (TC); cisplatin 80 mg/m(2) on day 1 plus gemcitabine 1000 mg/m(2) on days 1, 8 every 3 weeks (GP); and cisplatin 80 mg/m(2) on day 1 plus vinorelbine 25 mg/m(2) on days 1, 8 every 3 weeks (NP). RESULTS: The response rate, median survival time, and 1-year survival rate were 31.0%, 13.9 months, 59.2%, respectively, in IP; 32.4%, 12.3 months, 51.0% in TC; 30.1%, 14.0 months, 59.6% in GP; and 33.1%, 11.4 months, 48.3% in NP. No statistically significant differences were found in response rate or overall survival, but the non-inferiority of none of the experimental regimens could be confirmed. All the four regimens were well tolerated. CONCLUSION: The four regimens have similar efficacy and different toxicity profiles, and they can be used to treat advanced NSCLC patients.

As functional ABCB1 haplotypes were recently reported in the promoter region of the gene, we resequenced the ABCB1 distal promoter region, along with other regions (the enhancer and proximal promoter regions, and all 28 exons), in a total of 533 Japanese subjects. Linkage disequilibrium (LD) analysis based on 92 genetic variations revealed 4 LD blocks with the same make up as previously described (Blocks -1, 1, 2 and 3), except that Block 1 was expanded to include the distal promoter region, and that a new linkage between polymorphisms -1,789G>A in the distal promoter region and IVS5 + 123A>G in intron 5 was identified. We re-assigned Block 1 haplotypes, and added novel haplotypes to the other 3 blocks. The reported promoter haplotypes were further classified into several types according to tagging variations within Block 1 coding or intronic regions. Our current data reconfirm the haplotype profiles of the other three blocks, add more detailed information on functionally-important haplotypes in Block 1 and 2 in the Japanese population, and identified differences in haplotype profiles between ethnic groups. Our updated analysis of ABCB1 haplotype blocks will assist pharmacogenetic and disease-association studies carried out using Asian subjects.

BACKGROUND: Amrubicin, a totally synthetic 9-amino-anthracycline, demonstrated excellent single-agent activity for extensive-stage small-cell lung cancer (ED-SCLC). The aims of this trial were to determine the maximum-tolerated doses (MTD) of combination therapy with amrubicin and cisplatin, and to assess the efficacy and safety at their recommended doses (RD). PATIENTS AND METHODS: Eligibility criteria were patients having histologically or cytologically proven measurable ED-SCLC, no previous systemic therapy, an Eastern Cooperative Oncology Group performance status of 0-2 and adequate organ function. Amrubicin was administered on days 1-3 and cisplatin on day 1, every 3 weeks. RESULTS: Four patients were enrolled at dose level 1 (amrubicin 40 mg/m(2)/day and cisplatin 60 mg/m(2)) and three patients at level 2 (amrubicin 45 mg/m(2)/day and cisplatin 60 mg/m(2)). Consequently, the MTD and RD were determined to be at level 2 and level 1, respectively. The response rate at the RD was 87.8% (36/41). The median survival time (MST) was 13.6 months and the 1-year survival rate was 56.1%. Grade 3/4 neutropenia and leukopenia occurred in 95.1% and 65.9% of patients, respectively. CONCLUSIONS: The combination of amrubicin and cisplatin has demonstrated an impressive response rate and MST in patients with previously untreated ED-SCLC.

Irinotecan (CPT-11) has been shown to exhibit excellent antitumour activity against small-cell lung cancer (SCLC). A multi-institutional phase II study was therefore conducted to evaluate the efficacy and toxicity of CPT-11 combined with cisplatin (CDDP) and etoposide (ETOP) (PEI regimen) for the treatment of sensitive relapsed SCLC. Patients who responded to first-line chemotherapy but relapsed more than 8 weeks after the completion of first-line therapy (n=40) were treated using the PEI regimen, which consisted of CDDP (25 mg m(-2)) weekly for 9 weeks, ETOP (60 mg m(-2)) for 3 days on weeks 1, 3, 5, 7, and 9, and CPT-11 (90 mg m(-2)) on weeks 2, 4, 6, and 8 with granulocyte colony-stimulating factor support. Five complete responses and 26 partial responses were observed, and the overall response rate was 78% (95% confidence interval 61.5-89.2%). The median survival time was 11.8 months, and the estimated 1-year survival rate was 49%. Grade 3/4 leucocytopenia, neutropenia, and thrombocytopenia were observed in 55, 73, and 33% of the patients, respectively. Nonhaematological toxicities were mild and transient in all patients. In conclusion, the PEI regimen is considered to be highly active and well tolerated for the treatment of sensitive relapsed SCLC.

BACKGROUND: To evaluate the efficacy and safety of treatments for advanced non-small-cell lung cancer in elderly patients aged 75 years or older, we conducted a phase II study of cisplatin and docetaxel administered in three consecutive weekly infusions. PATIENTS AND METHODS: The eligibility criteria for the study included the presence of chemotherapy-naive advanced non-small-cell lung cancer, age > or =75 years, Eastern Cooperative Oncology Group performance status of 0 or 1, a measurable lesion, adequate organ functions and signed informed consent. The chemotherapy regimen consisted of cisplatin (25 mg/m(2)) and docetaxel (20 mg/m(2)) on days 1, 8 and 15 every 4 weeks. RESULTS: Between February 2000 and March 2002, 34 elderly patients with non-small-cell lung cancer were enrolled in the study and 33 patients were treated. Two complete responses and 15 partial responses were obtained for an objective response rate of 52% in 33 treated patients. The median survival period was 15.8 months, and the 1-year survival rate was 64%. Toxicities were mild with no grade 4 toxicities. Only grade 3 leukopenia (6%), neutropenia (12%), anemia (3%), hyponatremia (3%) and nausea/vomiting (3%) were observed. CONCLUSION: Cisplatin and docetaxel administered in three consecutive weekly infusions was safe and effective for the treatment of elderly patients with chemotherapy-naive non-small-cell lung cancer.

BACKGROUND: The standard treatment for patients with locoregional recurrence of non-small cell lung cancer (NSCLC) after complete resection has not been established. The aim of this study was to evaluate clinicopathologic characteristics, type of locoregional recurrence, pattern of subsequent failure, and survival after the recurrence. METHODS: Of 743 patients undergoing pulmonary resection for NSCLC in the National Cancer Center Hospital between 1990 and 1995, we retrospectively reviewed the medical charts of the 43 patients (5.8 %) found to have locoregional recurrence without distant metastasis or pleural or pericardial involvement. RESULTS: The median time to locoregional recurrence was 13.6 months (range: 1.6 - 85.8 months). The most frequent site of recurrence was the mediastinal nodes in 21 of 43 patients (49 %). 33 patients (77 %) received further treatment for the recurrence: thoracic irradiation in 26, surgery in two, systemic chemotherapy in two, and a combination of the above in 3 patients. Subsequent distant failure was detected in 26 (68 %) of the 38 patients assessable for the analysis of failure pattern: lung in 11, brain in 6, bone in 5, and others in 13. The median interval from the recurrence to distant failure was 8.4 months (range: 1.7-56.4 months). The median survival time after diagnosis of the locoregional recurrence was 10.5 months (range: 0-74.0 months). A multivariate analysis showed that local therapy for the locoregional recurrence had no significant impact on postrecurrent survival or distant failure-free survival. CONCLUSIONS: Many patients with postoperative locoregional recurrence developed distant metastases early after the first recurrence. Systemic chemotherapy in addition to local therapy may be of benefit in this population.
