Abstract
The current S3 Lung Cancer Guidelines are edited with fundamental changes to the previous edition based on the dynamic influx of information to this field:The recommendations include de novo a mandatory case presentation for all patients with lung cancer in a multidisciplinary tumor board before initiation of treatment, furthermore CT-Screening for asymptomatic patients at risk (after federal approval), recommendations for incidental lung nodule management , molecular testing of all NSCLC independent of subtypes, EGFR-mutations in resectable early stage lung cancer in relapsed or recurrent disease, adjuvant TKI-therapy in the presence of common EGFR-mutations, adjuvant consolidation treatment with checkpoint inhibitors in resected lung cancer with PD-L1 ≥ 50%, obligatory evaluation of PD-L1-status, consolidation treatment with checkpoint inhibition after radiochemotherapy in patients with PD-L1-pos. tumor, adjuvant consolidation treatment with checkpoint inhibition in patients withPD-L1 ≥ 50% stage IIIA and treatment options in PD-L1 ≥ 50% tumors independent of PD-L1status and targeted therapy and treatment option immune chemotherapy in first line SCLC patients.Based on the current dynamic status of information in this field and the turnaround time required to implement new options, a transformation to a "living guideline" was proposed.

Chai Y, Ma Y, Feng W, Lu H, Jin L. Effect of surgery on survival in patients with stage III N2 small cell lung cancer: propensity score matching analysis and nomogram development and validation. World J Surg Oncol 2021; 19:258. [PMID: 34461929 PMCID: PMC8404296 DOI: 10.1186/s12957-021-02364-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Accepted: 08/10/2021] [Indexed: 12/25/2022] Open
Abstract
Background The standard treatment of stage III N2 small cell lung cancer (SCLC) is concurrent chemoradiation, and surgery is not recommended. This study was aimed to evaluate whether surgery has survival benefits in patients with stage III N2 SCLC and investigate the factors influencing survival of surgery. Methods Patients diagnosed with stage T1-4N2M0 SCLC from 2004 to 2015 were selected from the Surveillance Epidemiology End Results database. Propensity score matching (PSM) was used to balance confounders between patients who underwent surgery and those treated with radiation and/or chemotherapy. We compared overall survival (OS) of the two groups using Kaplan-Meier curves and a Cox proportional hazard model. We also identified prognostic factors in patients with surgical resection, and a nomogram was developed and validated for predicting postoperative OS. Results −A total of 5576 patients were included in the analysis; of these, 211 patients underwent surgery. PSM balanced the differences between the two groups. The median OS was longer in the surgery group than in the non-surgery group (20 vs. 15 months; p = 0.0024). Surgery was an independent prognostic factor for longer OS in the multivariate Cox regression analysis, and subgroup analysis revealed a higher survival rate in T1 stage patients treated with surgery (hazard ratio = 0.565, 95% confidence interval: 0.401–0.798; p = 0.001). In patients who underwent surgery, four prognostic factors, including age, T stage, number of positive lymph nodes, and radiation, were selected into nomogram development for predicting postoperative OS. C-index, decision curve analyses, integrated discrimination improvement, and time-dependent receiver operating characteristics showed better performance in nomogram than in the tumor-node-metastasis staging system. Calibration plots demonstrated good consistency between nomogram predicted survival and actual observed survival. The patients were stratified into three different risk groups by prognostic scores and Kaplan-Meier curves showed significant difference between these groups. Conclusions These results indicate that surgery can prolong survival in patients with operable stage III N2 SCLC, particularly those with T1 disease. A nomogram that includes age, T stage, number of positive lymph nodes, and radiation can be used to predict their long-term postoperative survival.

[PMID: 30854808 PMCID: PMC6449329 DOI: 10.1111/1759-7714.12943] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2018] [Revised: 11/21/2018] [Accepted: 11/24/2018] [Indexed: 11/30/2022] Open
Abstract
Background To date, few studies have evaluated the impact of lobectomy versus sublobar resection for early small cell lung cancer (SCLC). We investigated the survival rates of patients with pathological stage T1‐2N0M0 SCLC who underwent lobectomy or sublobar resection. Methods We identified 548 SCLC patients in the Surveillance, Epidemiology, and End Results database who underwent lobectomy or sublobar resection. Propensity score matching (PSM) and Cox regression analysis were used to adjust for baseline characteristics. Results The three‐year overall survival (OS) of patients treated with lobectomy (n = 376, 60%) was significantly higher than those treated with sublobar resection (n = 172, 38%). PSM and Cox multivariable analysis further confirmed this result (hazard ratio [HR] 0.543, 95% confidence interval [CI] 0.421–0.680; P < 0.001). The three‐year OS of patients treated with segmentectomy (n = 24, 54%) and wedge resection (n = 148, 36%) was not significantly different (HR 0.639, 95% CI 0.393–1.039; P = 0.071). Based on PSM analysis, segmentectomy conferred a superior survival advantage to patients relative to wedge resection (HR 0.466, 95% CI 0.221–0.979; P = 0.040). Conclusion Lobectomy correlated with superior survival. For patients in which lobectomy is unsuitable, prognosis following segmentectomy appears to be better than after wedge resection.

Abstract
Objective: The prognostic analysis of limited resection vs. lobectomy in stage IA small cell lung cancer (SCLC) remains scarce. Methods: Using the Surveillance, Epidemiology, and End Results registry (SEER) database, we identified patients who were diagnosed with pathological stage IA (T1a/bN0M0) SCLC from 2004 to 2013. The overall survival (OS) and lung cancer-specific survival (LCSS) rates of patients with different treatment schemes were compared in stratification analyses. Univariable and multivariable analyses were also performed to identify the significant predictors of OS and LCSS. Results: In total, we extracted 491 pathological stage IA SCLC patients, 106 (21.6%) of whom received lobectomy, 70 (14.3%) received sublobar resection and 315 (64.1%) received non-surgical treatment, respectively. There were significant differences among the groups based on different treatment schemes in OS (log-rank p < 0.0001) and LCSS (log-rank p < 0.0001). Furthermore, in subgroup analyses, we did not identify any differences between sublober resection group and lobectomy group in OS (log-rank p = 0.14) or LCSS (log-rank p = 0.4565). Patients with four or more lymph node dissection had better prognosis. Multivariable analyses revealed age, laterality, tumor location, and N number were still significant predictors of OS, whereas age, tumor location, and N number were significant predictors of LCSS. Conclusion: Surgery is an important component of multidisciplinary treatment for stage IA SCLC patients and sublober resection is not inferior to lobectomy for the specific patients.

Abstract
INTRODUCTION Patients with stage I small cell lung carcinoma (SCLC) are candidates for surgery; however, not much is known regarding the utilization of surgical resection in the management of stage I SCLC and the factors that determine the patient's ability to receive surgery. METHODS The Surveillance, Epidemiology and End Results database was used to identify patients with stage I SCLC from 2007 to 2013. Continuous variables were compared with 1-way analysis of variance, and categorical variables were compared with χ2 testing. Multivariable logistic regression analyses were used to obtain odds ratios. RESULTS Of the 1902 patients with stage I SCLC, 427 (22.4%) underwent resection, 116 (6.1%) resection and radiation, 815 (42.8%) received radiation alone, and 544 (28.6%) did not undergo surgery or radiation. Median overall survival for patients with surgery plus radiation was 60+ months, followed by surgery alone at 50 months, radiation at 27 months, and no resection/radiation 16 months. Patients with ≥ 4 lymph nodes removed during surgery had better overall survival of 60+ months compared with patients with < 4 lymph nodes removed (25 months); P < .001. Multivariate analysis demonstrated that elderly patients, men, African American individuals, Medicaid recipients, and patients with left-sided tumors were less likely to undergo resection. However, county-level socioeconomic factors, such as level of poverty, education, unemployment, and median income did not affect the likelihood of undergoing resection. CONCLUSIONS Fewer than one-third of all patients with stage I SCLC undergo resection despite better outcomes with resection. Elderly African American men with Medicaid insurance were less likely to receive resection.

Abstract
PURPOSES This systematic review addressed the following key questions on managing small cell lung cancer (SCLC): the sequence, timing, and dosing characteristics of primary thoracic radiotherapy (TRTx) for limited-stage disease; primary TRTx for extensive-stage disease; effect of prophylactic cranial irradiation (PCI); positron emission tomography (PET) for staging; treatment of mixed histology tumors; surgery; and second-line and subsequent-line treatment for relapsed/progressive disease. METHODS The review methods were defined prospectively in a written protocol. We primarily sought randomized controlled trials that compared the interventions of interest. RESULTS Robust evidence was lacking for all questions except PCI, for which a patient-level metaanalysis showed that PCI improves survival of SCLC patients who achieved complete response after primary therapy from 15.3 to 20.7% (p = 0.01). The case for concurrent over sequential radiation delivery rests largely on a single multicenter trial. Support for early concurrent therapy comes from one multicenter trial, but two other multicenter trials found no advantage. Metaanalysis did not find significant reductions in 2-year and 3-year mortality rates for early TRTx. Favorable results from a single-center trial on TRTx for extensive stage disease need replication in a multicenter setting. Relevant comparative studies were nonexistent for management of mixed histology disease and surgery for early limited SCLC. PET may be more sensitive in detecting extracranial disease than conventional staging modalities, but studies were of poor quality. CONCLUSIONS PCI improves survival among those with a complete remission to primary therapy. A research agenda is needed to optimize the effectiveness of TRTx and its components.

Abstract
Current therapy for small cell lung cancer (SCLC) consists of chemotherapy with or without radiotherapy. Radiotherapy is generally accepted as an essential treatment component of limited stage disease. However, the local failure rate after chemo- and radiotherapy is still high and ranges from 30 to 70%. Furthermore, despite having obtained a complete radiographic response, up to 75% of these patients will have residual disease in the tumor specimen, if resection is performed. Therefore, more effective means are needed to eradicate the primary tumor and to obtain an improved local disease control. Recent phase two trials of multimodal regimens for stage I-IIIA SCLC demonstrate that in selected patients with early stage SCLC the combination of surgery and chemotherapy with or without radiotherapy is feasible with low morbidity and mortality rates. The combination therapy results in satisfying long term outcome depending on the pathological tumor stage and a local disease control is achieved in almost all patients. It is remarkable that the pneumonectomy rate has decreased over the past decades from almost 100 to 27-39%. In order to confirm these promising results, a German multicenter prospective randomized phase III trial has been designed for patients with stage I-IIIA SCLC consisting of induction chemotherapy, followed by surgery, adjuvant thoracic radiotherapy and prophylactic cranial radiation compared to thoracic radiotherapy and prophylactic cranial radiation.

Abstract
The role of surgery in small cell lung cancer (SCLC) is controversial. Surgery has several potential advantages because it may reduce the frequency of local relapses, it does not impede the intensity of chemotherapy, it does not affect the bone marrow, and surgical staging may be of prognostic significance. Several smaller retrospective studies which focus on surgery alone, surgery with adjuvant chemotherapy or radiotherapy, or chemotherapy followed by adjuvant surgery have been reported. Five-year survival data have ranged from 10-50% according to stage, both T-status and nodal status appearing to be significant prognostic factors. Only one prospective randomized trial has been reported concerning the addition of surgery to chemotherapy alone. This trial does not favour surgery. The reason for this could be a selection bias in the smaller non-randomized studies or a result of stage migration. Nevertheless, surgery may yet play an important role in SCLC, especially in diagnosis and staging, and with new improved non-invasive staging procedures, such as positron emission tomography, resection may lead to cure in selected patients. Prospective randomized studies are needed to settle this issue.

Abstract
Critical care of patients with lung cancer requires a knowledge of the behavior of this malignancy and the implications of several prognostic variables. Lung cancer's location, cellular characteristics, and metastatic patterns predispose patients to many emergencies that may require critical care intervention. In this article, the author presents important background on the behavior of this malignancy, its treatment, and predicted critical care problems. Included is a discussion of complications such as spinal cord compression, superior vena cava syndrome, airway obstruction, pleural effusions, and neoplastic cardiac tamponade, with an overview of common paraneoplastic syndromes. A case study exemplifies a possible presentation and management of a patient with lung cancer and some of these complications.

Abstract
Small cell lung cancer (SCLC) rarely presents radiographically as a solitary pulmonary nodule (SPN). Twenty-five patients with this feature were identified among 408 individuals with SCLC at McGill University (Montreal, Quebec) from 1979 through 1984. Of these, 15 (60%) were confirmed on pathologic review as SCLC (ten intermediate cell, four oat cell, one indeterminate). Pathologic review of a control group comprising 24 other limited-disease patients who were long-term survivors (greater than 20 months) confirmed 20 (84%) as SCLC (eight intermediate cell, 12 oat cell). Ten of the 15 patients with SPN were resected whereas five had chemotherapy and/or radiotherapy as primary treatment. Postoperative chemotherapy was administered to most of the resected patients. The median survival of the 15 patients with SPN was 24 months, a significantly longer survival than the other patients with SCLC. This improved prognosis in patients with SPN may be due to smaller initial tumor burden or to a fundamental biologic difference between SPN and other forms of SCLC.

Abstract
Reviewing the outcome of 70 cases of clinically localized small cell lung cancer (SCLC) treated with combined modality treatment, we attempted to define the role of resection in this disease. The survival rate for all cases was 37 per cent at 2 years and 23 per cent at 3 years with a median survival time (MST) of 14 months. For 25 resected cases the overall 5-year survival rate was 37 per cent with an MST of 26 months. According to clinical staging, 5-year survival was 64 per cent for stage I and 20 per cent for stage II. However, none of the stage III cases achieved long-term survival, of over 3 years. In 45 non-resected cases, the overall response rate was 84 per cent with a 44 per cent complete response. The overall survival rate was 27 per cent at 2 years and 14 per cent at 3 years with an MST of 11 months. The 20 cases who achieved complete response had an MST of 26 months with 51 per cent alive at 2 years and 19 per cent at 5 years. Thus, we consider that lung resection is definitely indicated in cases with stage I and probably stage II SCLC. For stage III, however, particularly in cases with N2 disease, resection seems to offer no special benefit in favor of survival compared to combination chemotherapy and radiotherapy.

Abstract
Analyses of the St. Francis Medical Center Cancer Registry for a 30-year period corroborated the publicized information of a gradual increase in the incidence of lung cancer in women and a recent decrease in the incidence among men. Our objectives were to highlight the biological and clinical features of lung cancer in women with the adoption and utilization of primary and secondary preventive measures.

Abstract
The diagnostic role of surgical procedures in small cell lung carcinoma (SCLC) is well established. The therapeutic role of surgery has changed over the years. At present, curative resection is the treatment of choice in peripheral T1-2 N0M0 SCLC, and adjuvant chemotherapy may be beneficial. Surgery is also indicated in SCLC patients diagnosed by a limited pathologic sample in whom the clinical course suggests nonsmall cell lung carcinoma (NSCLC). The resection may reveal either a mixed tumor or an alternate diagnosis and may be potentially curative. Surgery, at the time of maximal response to chemotherapy in T3N0M0 SCLC, may be curative and reveal the presence of NSCLC elements. The best survival is in patients found to be tumor-free at surgery, and the worst survival is in N2 patients.

Abstract
Out of 52 consecutive patients resected for small cell lung carcinoma (SCLC) from 1976 to 1986, 19 were selected because they underwent nonradical surgery, 10 of them for locoregional spread and 9 for distant metastases. Of the former subset all received postoperative radiotherapy and 8 chemotherapy also. Three patients are alive and disease-free 37, 56 and 91 months after resection. Four patients had a distant recurrence, and 3 a locoregional failure. Patients of the latter subgroup received chemotherapy in 7 instances. None survived more than 16 months, distant metastases being the cause of death. In these patients NO status was associated with 13.3 months of mean survival, N1 with 8.5 months, and N2 with 6.7 months. Surgery and adjuvant treatments seem effective in achieving local control of SCLC despite nonradical resections. Tumor burden at locoregional sites does not preclude the possibility of long term survival.

Abstract
Small cell undifferentiated carcinoma represents a subtype of lung cancer that possesses biologic and clinical characteristics that make it significantly distinct from other forms. A major impact on the natural history of this disease has been accomplished during the past 15 years, including the potential for cure by non-surgical treatment modalities. Further progress in the management of this disorder has been impaired by a number of factors that appear to be inherent to the biology of the tumor and its clinical features. Analysis of initial clinical trials and more detailed examination of this tumor in vitro have permitted the elucidation of many barriers to curative outcome presently being evaluated at the laboratory and clinical levels. These include clear biologic and morphologic heterogeneity; problems with chemotherapy responsiveness including drug resistance; the potential for combining chemotherapy and radiation modalities; the re-examination of the role of surgical intervention in selected patients; and the need to deal with central nervous system dissemination of tumor cells. Further advances in this disease will be dependent on the successful integration of laboratory and clinical disciplines.
