Abstract
OBJECTIVES Immune checkpoint inhibitors (ICIs) are effective treatment options for patients with advanced non-small cell lung cancer (NSCLC); however, there is a dearth of data on outcomes of patients receiving ICIs for postoperative recurrence. The objective of this study was to investigate the short- and long-term outcomes of patients who received ICIs for postoperative recurrence. METHODS A retrospective chart review was performed to identify consecutive patients who received ICIs for postoperative recurrence of NSCLC. We investigated therapeutic responses, adverse events, progression-free survival (PFS), and overall survival (OS). Survival outcomes were estimated using the Kaplan-Meier method. Univariable and multivariable analyses were performed using the Cox proportional hazards model. RESULTS Eighty-seven patients, with a median age of 72 years were identified between 2015 and 2022. The median follow-up period after ICI initiation was 13.1 months. Adverse events of grade ≥ 3 were observed in 29 (33.3%) patients, including 17 (19.5%) patients with immune-related adverse events. The median PFS and OS of the whole cohort were 3.2 and 17.5 months, respectively. Limited to those receiving ICIs as first-line therapy, the median PFS and OS were 6.3 and 25.0 months, respectively. On multivariable analysis, smoking history (HR: 0.29, 95% CI 0.10-0.83) and non-squamous cell histology (HR: 0.25, 95% CI 0.11-0.57) were associated with more favorable PFS in patients receiving ICIs as first-line treatment. CONCLUSIONS Outcomes in patients receiving ICIs as first-line treatment appear acceptable. A multi-institutional study is required to confirm our findings.

Abstract
OBJECTIVES To clarify survival outcomes and prognostic factors of patients receiving epidermal growth factor receptor (EGFR) - tyrosine kinase inhibitors (TKIs) as first-line treatment for postoperative recurrence. METHODS A retrospective chart review was performed to identify consecutive patients who received EGFR-TKIs as first-line treatment for postoperative recurrence of non-small-cell lung cancer (NSCLC) harbouring EGFR gene mutations at our institution between August 2002 and October 2020. Therapeutic response, adverse events, progression-free survival (PFS) and overall survival (OS) were investigated. Survival outcomes were assessed using the Kaplan–Meier analysis. The Cox proportional hazards model was used for univariable and multivariable analyses. RESULTS Sixty-four patients were included in the study. The objective response and disease control rates were 53% and 92%, respectively. Grade 3 or greater adverse events were noted in 4 (6.3%) patients, including 1 patient (1.6%) of interstitial pneumonia. The median follow-up period was 28.5 months (range 3–202 months). The total number of events was 43 for PFS and 23 for OS, respectively. The median PFS was 18 months, and the median OS was 61 months after EGFR-TKI treatment. In multivariable analysis, osimertinib showed a tendency to prolong PFS [hazard ratio (HR) 0.41, 95% confidence interval (CI) 0.12–1.1; P = 0.071], whereas the micropapillary component was significantly associated with shorter OS (HR 2.1, 95% CI 1.02–6.9; P = 0.045). CONCLUSIONS EGFR-TKIs as first-line treatment appeared to be a reasonable treatment option in selected patients with postoperative recurrent EGFR-mutated NSCLC. Osimertinib and the micropapillary component may be prognostic factors.

Primary Tumor Resection Is Associated with a Better Outcome among Advanced EGFR-Mutant Lung Adenocarcinoma Patients Receiving EGFR-TKI Treatment. Oncology 2020; 99:32-40.

Abstract
OBJECTIVES The characteristics and efficacy of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) in advanced EGFR-mutant lung adenocarcinoma patients with primary tumor resection (PTR) is not yet clear. METHODS We enrolled advanced EGFR-mutant lung adenocarcinoma patients with EGFR-TKI as first-line therapy to access the impact of PTR on the outcomes. RESULTS A total of 466 patients were enrolled with 76 patients (16.3%) undergoing PTR; 59 patients recurred after curative surgery, while 17 patients underwent surgery as diagnostic purposes. PTR patients displayed a better performance status, a lower metastatic burden, and much less measurable diseases (30.3 vs. 97.4%, p < 0.001). PTR patients experienced a significantly longer progression-free survival (25.1 [95% CI 16.6-33.7] vs. 9.4 [95% CI 8.4-10.4] months; aHR 0.40 [95% CI 0.30-0.54], p < 0.001) and overall survival (56.8 [95% CI 36.3-77.2] vs. 31.8 [95% CI 28.2-35.4] months; aHR 0.57 [95% CI 0.39-0.84], p = 0.004). Survival advantage was still observed while comparing PTR patients with the better performance and lower metastatic burden subgroup found within the non-resection group. Moreover, the progression-free survival and overall survival of 11 patients who were found having pleural metastases during surgery and underwent PTR plus pleural biopsy, were also longer than those with pure N0--1/M1a-malignant pleural effusion disease in the non-resection group (n = 19) (p < 0.001 and p = 0.002, respectively). CONCLUSION PTR was associated with significantly better outcomes in advanced lung adenocarcinoma patients treated with EGFR-TKI. Further studies are needed to evaluate the biological role of PTR among these patients.

Propensity-matched analysis of adjuvant chemotherapy for completely resected Stage IB non-small-cell lung cancer patients. Lung Cancer 2019; 133:75-82. [PMID: 31200832 DOI: 10.1016/j.lungcan.2019.04.024] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2018] [Revised: 04/18/2019] [Accepted: 04/23/2019] [Indexed: 12/25/2022]
Abstract
BACKGROUND The use of adjuvant chemotherapy (ACT) in completely resected stage IB non-small cell lung cancer (NSCLC) is still controversial. The divergent outcomes of prospective trials have created uncertainty as to the utility of ACT in stage IB NSCLC. This study assesses the effect of postoperative adjuvant chemotherapy in stage IB patients in clinical practice. METHODS Patients with pT2aN0M0 stage IB NSCLC who underwent complete resection from 2004 to 2015 were identified from prospectively collected databases in two medical centers. The log-rank test was used to compare overall survival (OS) and disease free survival (DFS). Fine and Gray's competing risks regression model was built to identify predictors of cancer-specific survival. One to one propensity-score matching (PSM) was performed to reduce the selection bias and additional analyses were performed on these subgroups. RESULTS Of 1005 patients identified for the study, 202 (20.1%) received ACT and 803 (79.9%) underwent surgery alone (observation group). Compared with the observation group, patients who underwent ACT were younger (p < 0.001), had larger tumors (p = 0.004), and had higher rates of squamous cell carcinoma (p < 0.001) and lymphovascular invasion (p = 0.017). After propensity score matching, 196 pairs of patients were 1:1 matched in the two groups and all baseline characteristics were well balanced. ACT was not associated with improved survival (including OS, DFS; all log-rank p > 0.05) in both unmatched and matched (196 pairs) cohorts. In subgroup analysis of the matched population, ACT was not associated with survival benefits for patients regardless of whether their tumors measured <4 cm or ≥4 cm (both log-rank p > 0.05). CONCLUSIONS In patients with completely resected stage IB (T2aN0M0) NSCLC, ACT is not associated with improved prognosis. Further large multicenter studies are needed to confirm these findings.

Abstract
Background The prognosis of patients with epidermal growth factor receptor (EGFR) mutant adenocarcinoma of the lung (Mt) and EGFR wild-type adenocarcinoma (Wt) after complete resection of the lung differ; however, the mechanisms responsible for these differences remain unclear. The present study examined the post-operative prognosis of recurrent pulmonary adenocarcinoma patients to evaluate the clinicopathological nature of Mt and contribution of EGFR - tyrosine kinase inhibitors (TKI) to the prognosis of patients. Methods The subjects were 237 patients with recurrent pulmonary adenocarcinoma who underwent EGFR mutation analysis, and consisted of 108 patients with recurrent Mt and 129 with recurrent Wt. Multivariate analyses were performed to investigate whether the EGFR status is a prognostic factor for relapse-free survival (RFS) and post-relapse survival (PRS). Results RFS was significantly better in Mt than in Wt patients; median RFS were 20.2 and 13.3 months, respectively (p < 0.001). The multivariate analysis identified EGFR mutation as an independent prognostic factor for a favorable RFS (hazard ratio = 0.68; 95% confidence interval, 0.52–0.89). Although, no significant differences were observed in PRS between Mt and Wt patients (median PRS were 33.9 and 28.2 months, respectively; p = 0.360), PRS was significantly better in Mt with EGFR - TKI than in Wt and Mt patients without EGFR - TKI (p = 0.008 and p < 0.001, respectively). PRS was also significantly better in Wt than in Mt patients without EGFR - TKI (p < 0.001). The multivariate analysis identified the administration of EGFR - TKI as an independent prognostic factor for PRS (hazard ratio = 0.60; 95% confidence interval, 0.40–0.89). Conclusions EGFR mutation tumors were associated with a significantly better RFS for recurrent pulmonary adenocarcinoma after curative resection of the lung, which represented the less aggressive nature of Mt tumors. However, patients with Mt did not have a favorable prognosis after recurrence unless they received EGFR - TKI.

Abstract
After pulmonary resection for non-small-cell lung cancer, some patients with postoperative recurrence and mutated epidermal growth factor receptor (EGFR) subsequently receive EGFR-tyrosine kinase inhibitors (EGFR-TKIs). Osimertinib may be efficacious if those patients become resistant to the 1st-line EGFR-TKI because of the T790M mutation. We recently performed thoracoscopic rebiopsy to detect the T790M mutation in 4 patients who became resistant to the 1st-line EGFR-TKI treatment for postoperative recurrence. Our limited experience suggests that thoracoscopic biopsy is associated with limited morbidity, can help detect the T790M mutation and may improve the management of select patients with acquired resistance to the 1st-line EGFR-TKIs.

Abstract
PURPOSE We reported previously a phase II study of adjuvant chemotherapy consisting of four cycles of vinorelbine (25 mg/m2) and cisplatin (40 mg/m2), given on days 1 and 8, every 4 weeks, to Japanese patients with completely resected stage II or III non-small cell lung cancer (NSCLC; UMIN 000005055). However, the follow-up was too short for us to evaluate a definitive 5-year overall survival rate and after-effects. METHODS Between December 2006 and January 2011, 60 patients were enrolled in this study. We analyzed relapse-free and overall survival, long-lasting adverse effects, the influence of treatment on recurrent tumors, and the development of a second primary cancer, in relation with the regimen. RESULTS After a median follow-up period of 95.8 months, the 5-year relapse-free and overall survival rates were 51.7 and 76.7%, respectively. Neuralgia developed in one patient and this was the only case of a long-lasting adverse effect. Recurrence developed in 31 patients, 29 of whom received intensive treatment. Although 16 s (or more) primary neoplasms developed among 13 patients, these were common carcinomas in Japan and did not include sarcoma or hematologic malignancies. CONCLUSION Adjuvant vinorelbine and cisplatin chemotherapy showed encouraging relapse-free and overall survival rates, and long-term safety in Japanese patients with resected NSCLC.

Abstract
BACKGROUND advanced-stage non-small cell lung cancer (NSCLC) is characterized by having limited treatment options and thus a poor prognosis. However, new treatment options, in the form of targeted agents (TA), have emerged during recent years. This systematic review aims to provide an overview of the accessible literature in PubMed evaluating TA used on NSCLC patients, and the resulting survival outcomes. METHOD this systematic literature review was conducted by reviewing all relevant literature in PubMed. Six separate searches were performed: Three searches where controlled entry terms were used and three free text searches. Furthermore, other relevant publications were included manually. A total of seventy-two studies met the search criteria and were thus further analyzed and evaluated. RESULTS In the included studies, various TAs and their effect on different molecular targets have been evaluated. Clinical responses vary considerably among the different genetic aberrations. The majority of studies evaluated TA for epidermal growth factor receptor (EGFR) mutations and TA for echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) rearrangements. Studies regarding the use of TA for Rat sarcoma (RAS), rapidly accelerated fibrosarcoma (RAF), ROS proto-oncogene 1 (ROS1) rearrangement, Receptor tyrosine-protein kinase erbB-2 (ERBB2), Phosphatidylinositol 3-kinase (PIK3CA)/v-akt murine thymoma viral oncogene homolog; protein kinase B(AKT)/Phosphatase and tensin homolog deleted on chromosome 10(PTEN), The mammalian target of rapamycin (mTOR), and Mesenchymal-epithelial transition factor (MET) were included as well. In general, studies comparing treatment outcomes in EGFR-mutated patients and EML4-ALK (ALK) rearranged patients after use of either TA or standard chemotherapy, present significant better results after TA. CONCLUSIONS This systematic review provides an overview of available literature in PubMed regarding NSCLC and TA. Included studies point toward that TA appears to be a promising therapeutic tool in treating NSCLC patients and use of TA is expected to result in improved treatment outcomes.
