Full Text Available Lung cancer is the leading cause of cancer death in industrialized countries with progressive increase of its mortality rate. Non Small Cell Lung Cancer (NSCLC is approximately 80-85% of all lung cancers, being adenocarcinoma and squamous cell carcinoma the most common histologies. The majority of the patients with stage III clinical stage, presents a mediastinal lymph node involvement described with computed tomography (TC and/or positron emission tomography (PET. The current approach to patients with NSCLC is multidisciplinary, especially for those staged as potentially operable, both for staging and for a correct definition of best treatment strategy. Updated international and national Guidelines and recommendations can provide valuable support to the clinician.The case described concerns the accidental detection of a tumour in the lung in a 58-year-old man with arterial hypertension controlled with ACE inhibitors. The treatments agreed after a multidisciplinary approach are cisplatin and docetaxel, the surgical resection, and the radiotherapy. After three months the patient has neither metastasis nor relapse.

The purpose was to determine the efficacy and safety of induction chemotherapy followed by concomitant chemoradiotherapy in the treatment of stage III non-small cell lung cancer and whether the response to induction chemotherapy can predict the response to subsequent chemoradiotherapy and survival. In conclusion, there is a statistically significant relationship not only between the response to ICT and the response to CCrt, but also between the response to ICT and the local outcome and survival.

Lung cancer is the leading cause of cancer-related death worldwide. Current clinical screening methods to detect lung cancer are expensive and associated with many complications. Raman spectroscopy is a spectroscopic technique that offers a convenient method to gain molecular information about biological samples. In this study, we measured the serum Raman spectral intensity of healthy volunteers and patients with different stages of non-small cell lung cancer. The purpose of this study was to evaluate the application of serum laser Raman spectroscopy as a low cost alternative method in the screening and staging of non-small cell lung cancer (NSCLC). The Raman spectra of the sera of peripheral venous blood were measured with a LabRAM HR 800 confocal Micro Raman spectrometer for individuals from five groups including 14 healthy volunteers (control group), 23 patients with stage I NSCLC (stage I group), 24 patients with stage II NSCLC (stage II group), 19 patients with stage III NSCLC (stage III group), 11 patients with stage IV NSCLC (stage IV group). Each serum sample was measured 3 times at different spots and the average spectra represented the signal of Raman spectra in each case. The Raman spectrum signal data of the five groups were statistically analyzed by analysis of variance (ANOVA), principal component analysis (PCA), linear discriminant analysis (LDA), and cross-validation. Raman spectral intensity was sequentially reduced in serum samples from control group, stage I group, stage II group and stage III/IV group. The strongest peak intensity was observed in the control group, and the weakest one was found in the stage III/IV group at bands of 848 cm -1 , 999 cm -1 , 1152 cm -1 , 1446 cm -1 and 1658 cm -1 (P Raman spectroscopy can effectively identify patients with stage I, stage II or stage III/IV Non-Small Cell Lung cancer using patient serum samples.

Purpose: To compare dose-volume histograms (DVH) in patients with non-small-cell lung cancer (NSCLC) treated by photon or proton radiotherapy. Methods and Materials: Dose-volume histograms were compared between photon, including three-dimensional conformal radiation therapy (3D-CRT), intensity-modulated radiation therapy (IMRT), and proton plans at doses of 66 Gy, 87.5 Gy in Stage I (n = 10) and 60-63 Gy, and 74 Gy in Stage III (n 15). Results: For Stage I, the mean total lung V5, V10, and V20 were 31.8%, 24.6%, and 15.8%, respectively, for photon 3D-CRT with 66 Gy, whereas they were 13.4%, 12.3%, and 10.9%, respectively, with proton with dose escalation to 87.5 cobalt Gray equivalents (CGE) (p = 0.002). For Stage III, the mean total lung V5, V10, and V20 were 54.1%, 46.9%, and 34.8%, respectively, for photon 3D-CRT with 63 Gy, whereas they were 39.7%, 36.6%, and 31.6%, respectively, for proton with dose escalation to 74 CGE (p = 0.002). In all cases, the doses to lung, spinal cord, heart, esophagus, and integral dose were lower with proton therapy even compared with IMRT. Conclusions: Proton treatment appears to reduce dose to normal tissues significantly, even with dose escalation, compared with standard-dose photon therapy, either 3D-CRT or IMRT

Purpose: We report long-term disease control, survival, and toxicity for patients with locally advanced non-small cell lung cancer prospectively treated with concurrent proton therapy and chemotherapy on a nonrandomized case-only observational study. Methods: All patients received passive-scatter proton therapy, planned with 4D-CT–based simulation; all received proton therapy concurrent with weekly chemotherapy. Endpoints were local and distant control, disease-free survival (DFS), and overall survival (OS). Results: The 134 patients (21 stage II, 113 stage III; median age 69 years) had a median gross tumor volume (GTV) of 70 cm 3 (range, 5–753 cm 3 ); 77 patients (57%) received 74 Gy(RBE), and 57 (42%) received 60–72 Gy(RBE) (range, 60–74.1 Gy(RBE)). At a median follow-up time of 4.7 years, median OS times were 40.4 months (stage II) and 30.4 months (stage III). Five-year DFS rates were 17.3% (stage II) and 18.0% (stage III). OS, DFS, and local and distant control rates at 5 years did not differ by disease stage. Age and GTV were related to OS and DFS. Toxicity was tolerable, with 1 grade 4 esophagitis and 16 grade 3 events (2 pneumonitis, 6 esophagitis, 8 dermatitis). Conclusion: This report of outcomes after proton therapy for 134 patients indicated that this regimen produced excellent OS with tolerable toxicity

The results of treatment of 141 patients with stage III non-small cell lung cancer (NSCLC) who received definitive radiation therapy at Gunma University Hospital between 1976 and 1989 were retrospectively analyzed. Radiation was given with standard fractionation for a planned prophylactic dose of 40 Gy over 4 weeks and a definitive dose of 60 Gy over 6 weeks or more. The two- and five-year survival rates were 27% and 12% for stage IIIA, and 18% and 8% for stage IIIB, respectively (P=0.052). By univariate analysis, a primary tumor less than 5 cm in diameter was also an important predictor of survival (P=0.008). As for tumor location, the patients with primary tumors in the upper lobes or the superior segment of the lower lobes of the lung lived longer than those with primary tumors at any other site (P=0.032). Patients with epidermoid carcinoma had a higher survival rate at 5 years than those with other histologic types (14% vs 3%, P=0.074). Multivariate analysis showed that among tumor characteristics, the site of the primary tumor, the pattern of tumor spread and N stage were significantly associated with overall survival. Among the patients with stage III NSCLC, those with stage IIIA epidermoid carcinoma in the upper lobe or the superior segment of the lower lobe of the lung were considered to be the most favorable candidates for definitive radiation therapy.

Seventy-four patients seen from January 1975 through December 1982 with clinical stage III M0 non-small-cell carcinoma of the lung were treated with a course of preoperative radiation therapy to be followed by surgical resection. Surgical resection was attempted 4 weeks later. All the patients except two were followed up for a minimum of 5 years or until death. Sixty-four patients (86%) had T3 tumors, while mediastinal nodal involvement was found in 41 (55%). The actuarial 5-year survival and disease-free survival rates for the entire group were 20% and 26%, respectively. Patients with a pathologically complete response had an actuarial disease-free survival rate of 50% at 5 years, compared with only 17% for those with gross residual disease at surgery. One-half of the patients with clinically uninvolved nodes were living disease free at 5 years, compared with only 20% of the patients with N2 disease. The patterns of failure are presented according to the histologic type and stage of the disease

The clinical effect of concomitant use of non-specific immunopotentiator OK-432 and/or PSK was studied about 172 cases of primary lung cancer (Stage III, IV). In 91 cases in stage III, fifty percent survival period was found to be 11.5 months for 63 cases with OK-432 and/or PSK, and 7.5 months for 28 cases without immunotherapy, respectively. In 81 cases in stage IV, fifty percent survival period was found to be 6.7 months for 45 cases with OK-432 and/or PSK, and 3.3 months for 36 cases without immunotherapy, respectively. (author)

Purpose: To compare preoperative chemotherapy (ChT) and preoperative chemoradiotherapy (ChT-RT) in operable Stage III non-small-cell lung cancer. Methods and Materials: This retrospective study analyzed all patients with pathologically confirmed Stage III (N2) non-small-cell lung cancer who initiated preoperative ChT or ChT-RT at Duke University between 1995 and 2006. Mediastinal pathologic complete response (pCR) rates were compared using a chi-square test. The actuarial overall survival, disease-free survival, and local control were estimated using the Kaplan-Meier method and compared using the log-rank test. Multivariate Cox regression analysis was also performed. Results: A total of 101 patients who initiated preoperative therapy with planned resection were identified. The median follow-up was 20 months for all patients and 38 months for survivors. The mediastinal lymph nodes were reassessed after preoperative therapy in 88 patients (87%). Within this group, a mediastinal pCR was achieved in 35% after preoperative ChT vs. 65% after preoperative ChT-RT (p = 0.01). Resection was performed in 69% after ChT and 84% after ChT-RT (p = 0.1). For all patients, the overall survival, disease-free survival, and local control rate at 3 years was 40%, 27%, and 66%, respectively. No statistically significant differences were found in the clinical endpoints between the ChT and ChT-RT subgroups. On multivariate analysis, a mediastinal pCR was associated with improved disease-free survival (p = 0.03) and local control (p = 0.03), but not overall survival (p = 0.86). Conclusion: Preoperative ChT-RT was associated with higher mediastinal pCR rates but not improved survival.

In patients with unresectable stage III non-small cell lung cancer, we performed chemotherapy and concurrent thoracic radiotherapy. Thirty-five registered patients were intravenously treated with cisplatin (80mg/m{sup 2}) on day 1 and vindesine (3mg/m{sup 2}) on days 1, 3 and were irradiated from days 1 to 10 with single doses of 2.5 Gy up to a total dosage of 20 Gy. Each course lasted 28 days. Patients received 3 courses, and a total dosage of 60 Gy was delivered. Response to this treatment was evaluable in terms of results in 35 patients. Twenty-two patients showed partial response (response rate 62.9%), 10 had no change, and 3 cases had progressive disease. In 7.5 to 37.8 months observation, three PR patients are alive for more than 24 months without recurrence, but eight PR patients died of local relapse, and the median survival time was 15.7 months. Throughout this treatment course, grade 4 leukopenia was noted in 66% and grade 3 thrombocytopenia was observed in 3%. However all were reversible condition and no treatment-related death was observed. However, two cases died due to complications of pulmonary abscess, which occurred in the area of radiation pulmonary fibrosis about one year later after treatment. Although this concurrent chemo-radiotherapy is a tolerable treatment for non-small cell lung cancer and obtained a good response rate, it did not improve the survival rate. (author).

Purpose: To compare the quality of volumetric modulated arc therapy (VMAT) or intensity-modulated radiation therapy (IMRT) plans generated by an automated inverse planning system with that of dosimetrist-generated IMRT treatment plans for patients with stage III lung cancer. Methods and Materials: Two groups of 8 patients with stage III lung cancer were randomly selected. For group 1, the dosimetrists spent their best effort in designing IMRT plans to compete with the automated inverse planning system (mdaccAutoPlan); for group 2, the dosimetrists were not in competition and spent their regular effort. Five experienced radiation oncologists independently blind-reviewed and ranked the three plans for each patient: a rank of 1 was the best and 3 was the worst. Dosimetric measures were also performed to quantitatively evaluate the three types of plans. Results: Blind rankings from different oncologists were generally consistent. For group 1, the auto-VMAT, auto-IMRT, and manual IMRT plans received average ranks of 1.6, 2.13, and 2.18, respectively. The auto-VMAT plans in group 1 had 10% higher planning tumor volume (PTV) conformality and 24% lower esophagus V70 (the volume receiving 70 Gy or more) than the manual IMRT plans; they also resulted in more than 20% higher complication-free tumor control probability (P+) than either type of IMRT plans. The auto- and manual IMRT plans in this group yielded generally comparable dosimetric measures. For group 2, the auto-VMAT, auto-IMRT, and manual IMRT plans received average ranks of 1.55, 1.75, and 2.75, respectively. Compared to the manual IMRT plans in this group, the auto-VMAT plans and auto-IMRT plans showed, respectively, 17% and 14% higher PTV dose conformality, 8% and 17% lower mean lung dose, 17% and 26% lower mean heart dose, and 36% and 23% higher P+. Conclusions: mdaccAutoPlan is capable of generating high-quality VMAT and IMRT treatment plans for stage III lung cancer. Manual IMRT plans could achieve quality

Commonly reported complications after concurrent chemoradiotherapy (CCRT) in patients with stage III non-small-cell lung cancer (NSCLC) include febrile neutropenia, radiation esophagitis, and pneumonitis. We studied the incidence of tumor cavitation and/or "tumor abscess" after CCRT in a single-institutional cohort. Between 2003 and 2010, 87 patients with stage III NSCLC underwent cisplatin-based CCRT and all subsequent follow-up at the VU University Medical Center. Diagnostic and radiotherapy planning computed tomography scans were reviewed for tumor cavitation, which was defined as a nonbronchial air-containing cavity located within the primary tumor. Pulmonary toxicities scored as Common Toxicity Criteria v3.0 of grade III or more, occurring within 90 days after end of radiotherapy, were analyzed. In the entire cohort, tumor cavitation was observed on computed tomography scans of 16 patients (18%). The histology in cavitated tumors was squamous cell (n = 14), large cell (n = 1), or adenocarcinoma (n = 1). Twenty patients (23%) experienced pulmonary toxicity of grade III or more, other than radiation pneumonitis. Eight patients with a tumor cavitation (seven squamous cell carcinoma) developed severe pulmonary complications; tumor abscess (n = 5), fatal hemorrhage (n = 2), and fatal embolism (n = 1). Two patients with a tumor abscess required open-window thoracostomy post-CCRT. The median overall survival for patients with or without tumor cavitation were 9.9 and 16.3 months, respectively (p = 0.09). With CCRT, acute pulmonary toxicity of grade III or more developed in 50% of patients with stage III NSCLC, who also had radiological features of tumor cavitation. The optimal treatment of patients with this presentation is unclear given the high risk of a tumor abscess.

43 patients with stage III NSCLC (non-small cell lung cancer) entered a phase II study aimed at evaluating the toxicity and the activity of a combined modality programme including an accelerated split-course schedule (type B) of thoracic radiation therapy and a combination chemotherapy with vinorelbine and carboplatin. An objective response was achieved in 18/42 evaluable patients (5 complete and 13 partial responses), for an overall response rate of 43% (95% confidence interval, 28-58%). Four complete responses had a duration which exceeded 16 months. Treatment was well tolerated; grade III myelotoxicity occurred in only 14% of patients and treatment was delayed in only 2 cases because of grade 3 oesophagitis. Both tolerability and efficacy data suggest that this regimen holds promise for the treatment of patients with stage III NSCLC. (author)

Lung cancer remains the leading cause of cancer-related mortality worldwide. Stage III non-small cell lung cancer (NSCLC) includes heterogeneous presentation of the disease including lymph node involvement and large tumour volumes with infiltration of the mediastinum, heart or spine. In the treatment of stage III NSCLC an interdisciplinary approach including radiotherapy is considered standard of care with acceptable toxicity and improved clinical outcome concerning local control. Furthermore, gross tumour volume (GTV) changes during definitive radiotherapy would allow for adaptive replanning which offers normal tissue sparing and dose escalation. A literature review was conducted to describe the predictive value of GTV changes during definitive radiotherapy especially focussing on overall survival. The literature search was conducted in a two-step review process using PubMed registered /Medline registered with the key words ''stage III non-small cell lung cancer'' and ''radiotherapy'' and ''tumour volume'' and ''prognostic factors''. After final consideration 17, 14 and 9 studies with a total of 2516, 784 and 639 patients on predictive impact of GTV, GTV changes and its impact on overall survival, respectively, for definitive radiotherapy for stage III NSCLC were included in this review. Initial GTV is an important prognostic factor for overall survival in several studies, but the time of evaluation and the value of histology need to be further investigated. GTV changes during RT differ widely, optimal timing for re-evaluation of GTV and their predictive value for prognosis needs to be clarified. The prognostic value of GTV changes is unclear due to varying study qualities, re-evaluation time and conflicting results. The main findings were that the clinical impact of GTV changes during definitive radiotherapy is still unclear due to heterogeneous study designs with varying quality

This study was designed to evaluate the feasibility and efficiency of giving cisplatin, etoposide, and OK-432 concurrently with conventional radiotherapy (RTx) for patient's with inoperable stage III, based on the TNM classification according to the International Union against Cancer staging system for lung cancer (1987) non-small cell lung cancer (NSCLC). From January 1992 to December 1994, 31 patients with cytologically or histologically confirmed stage III NSCLC were treated with RTx, to a total dose of 56-64 Gy, with concurrent daily oral administration of etoposide (25 mg) and cisplatin (20 mg) for 5 days during the third or fourth week from the start of RTx. The subcutaneous injection of 1 or 2 KE of OK-432, three times a week, for the duration of radiotherapy also started from the beginning of RTx. The number of eligible patients was 29 (26 men and 3 women). Their mean age was 66 years (range, 55-77 years). Six patients had an Eastern Cooperative Oncology Group performance status (PS) of 0; 15, 1; 8; 2. Three were stage IIIA, and 26, stage IIIB. Histologically, 2 had adenocarcinoma, 23, squamous cell carcinoma, and 4, large cell carcinoma. In 27 of the 29 patients, the RTx schedule was completed. There were no treatment-related deaths. Grade 4 toxicity (according to World Health Organisation criteria) leukopenia (700/μl) was observed in 1 patient. The response rate was 79% and the median survival was 17 months. Survival rates at 1, 2 and 3 years were 62%, 31%, and 21%, respectively. The local failure rate was 51%. The combination of cisplatin, etoposide, and OK-432, given concurrently with conventional RTx is feasible and effective for inoperable stage III NSCLC. (author)

Concurrent chemoradiotherapy (CCRT) is considered the standard treatment regimen in non-surgical locally advanced non-small cell lung cancer (NSCLC) patients and sequential chemoradiotherapy (SCRT) is recommended in patients who are unfit to receive CCRT or when the treatment volume is considered too large. In this study, we investigated the proportion of CCRT/SCRT in the Netherlands and Belgium. Furthermore, patient and disease characteristics associated with SCRT were assessed. An observational study was carried out with data from three independent national registries: the Belgian Cancer Registry (BCR), the Netherlands Cancer Registry (NCR) and the Dutch Lung Cancer Audit-Radiotherapy (DLCA-R). Differences in patient and disease characteristics between CCRT and SCRT were tested with unpaired t-tests (for continuous variables) and with chi-square tests (for categorical variables). A prognostic model was constructed to determine patient and disease parameters predictive for the choice of SCRT. This study included 350 patients from the BCR, 780 patients from the NCR and 428 patients from the DLCA-R. More than half of the stage III NSCLC patients in the Netherlands (55%) and in Belgium more than a third (35%) were treated with CCRT. In both the Dutch and Belgian population, higher age and more advanced N-stage were significantly associated with SCRT. Performance score, pulmonary function, comorbidities and tumour volume were not associated with SCRT. In this observational population-based study, a large treatment variation in non-surgical stage III NSCLC patients was observed between and within the Netherlands and Belgium. Higher age and N-stage were significantly associated with the choice for SCRT. Copyright © 2017 The Royal College of Radiologists. Published by Elsevier Ltd. All rights reserved.

To determine the recommended phase II dose of vinorelbine in combination with cisplatin and thoracic radiotherapy (TRT) in patients with unresectable stage III non-small cell lung cancer (NSCLC), 18 patients received cisplatin (80 mg/m 2 ) on day 1 and vinorelbine (20 mg/m 2 in level 1, and 25 mg/m 2 in level 2) on days 1 and 8 every 4 weeks for 4 cycles. TRT consisted of a single dose of 2 Gy once daily for 3 weeks followed by a rest of 4 days, and then the same TRT for 3 weeks to a total dose of 60 Gy. Fifteen (83%) patients received 60 Gy of TRT and 14 (78%) patients received 4 cycles of chemotherapy. Ten (77%) of 13 patients at level 1 and all 5 patients at level 2 developed grade 3-4 neutropenia. Four (31%) patients at level 1 and 3 (60%) patients at level 2 developed grade 3-4 infection. None developed ≥grade 3 esophagitis or lung toxicity. Dose-limiting toxicity was noted in 33% of the patients in level 1 and in 60% of the patients in level 2. The overall response rate (95% confidence interval) was 83% (59-96%) with 15 partial responses. The median survival time was 30.4 months, and the 1-year, 2-year, and 3-year survival rates were 72%, 61%, and 50%, respectively. In conclusion, the recommended dose is the level 1 dose, and this regimen is feasible and promising in patients with stage III NSCLC. (author)

Background: Acute radiation-induced esophagitis (ARIE) is one of main toxicities complicated by thoracic radiotherapy, influencing patients’ quality of life and radiotherapy proceeding seriously. It is difficult to be cured rapidly so far. Our phase I trial preliminarily showed that EGCG may be a promising strategy in the treatment of ARIE. Materials and methods: We prospectively enrolled patients with stage III lung cancer from the Shandong Tumor Hospital & Institute in China from January 2013 to September 2014. All patients received concurrent or sequential chemo-radiotherapy, or radiotherapy only. EGCG was administrated once ARIE appeared. EGCG was given with the concentration of 440 μmol/L during radiotherapy and additionally two weeks after radiotherapy. RTOG score, dysphagia and pain related to esophagitis were recorded every week. Results: Thirty-seven patients with stage IIIA and IIIB lung cancer were enrolled in this trial. In comparison to the original, the RTOG score in the 1st, 2nd, 3rd, 4th, 5th week after EGCG prescription and the 1st, 2nd week after radiotherapy decreased significantly (P = 0.002, 0.000, 0.000, 0.001, 0.102, 0.000, 0.000, respectively). The pain score of each week was significantly lower than the baseline (P = 0.000, 0.000, 0.000, 0.000, 0.006, 0.000, 0.000, respectively). Conclusion: This trial confirmed that the oral administration of EGCG is an effective and safe method to deal with ARIE. A phase III randomized controlled trial is expected to further corroborate the consequence of EGCG in ARIE treatment

Emerging Therapies for Stage III Non-Small Cell Lung Cancer: Stereotactic Body Radiation Therapy and Immunotherapy

Directory of Open Access Journals (Sweden)

Full Text Available The current standard of care for locally advanced non-small cell lung cancer (NSCLC includes radiation, chemotherapy, and surgery in certain individualized cases. In unresectable NSCLC, chemoradiation has been the standard of care for the past three decades. Local and distant failure remains high in this group of patients, so dose escalation has been studied in both single institution and national clinical trials. Though initial studies showed a benefit to dose escalation, phase III studies examining dose escalation using standard fractionation or hyperfractionation have failed to show a benefit. Over the last 17 years, stereotactic body radiation therapy (SBRT has shown a high degree of safety and local control for stage I lung cancers and other localized malignancies. More recently, phase I/II studies using SBRT for dose escalation after conventional chemoradiation in locally advanced NSCLC have been promising with good apparent safety. Immunotherapy also offers opportunities to address distant disease and preclinical data suggest immunotherapy in tandem with SBRT may be a rational way to induce an “abscopal effect” although there are little clinical data as yet. By building on the proven concept of conventional chemoradiation for patients with locally advanced NSCLC with a subsequent radiation dose intensification to residual disease with SBRT concurrent with immunotherapy, we hope address the issues of metastatic and local failures. This “quadmodality” approach is still in its infancy but appears to be a safe and rational approach to the improving the outcome of NSCLC therapy.

Purpose: Although patients with stage III non-small cell lung cancer (NSCLC) are homogeneous according to the TNM staging system, they form a heterogeneous group, which is reflected in the survival outcome. The increasing amount of information for an individual patient and the growing number of treatment options facilitate personalized treatment, but they also complicate treatment decision making. Decision support systems (DSS), which provide individualized prognostic information, can overcome this but are currently lacking. A DSS for stage III NSCLC requires the development and integration of multiple models. The current study takes the first step in this process by developing and validating a model that can provide physicians with a survival probability for an individual NSCLC patient. Methods and Materials: Data from 548 patients with stage III NSCLC were available to enable the development of a prediction model, using stratified Cox regression. Variables were selected by using a bootstrap procedure. Performance of the model was expressed as the c statistic, assessed internally and on 2 external data sets (n=174 and n=130). Results: The final multivariate model, stratified for treatment, consisted of age, gender, World Health Organization performance status, overall treatment time, equivalent radiation dose, number of positive lymph node stations, and gross tumor volume. The bootstrapped c statistic was 0.62. The model could identify risk groups in external data sets. Nomograms were constructed to predict an individual patient's survival probability ( (www.predictcancer.org)). The data set can be downloaded at (https://www.cancerdata.org/10.1016/j.ijrobp.2015.02.048). Conclusions: The prediction model for overall survival of patients with stage III NSCLC highlights the importance of combining patient, clinical, and treatment variables. Nomograms were developed and validated. This tool could be used as a first building block for a decision support system.

Purpose: The use of prophylactic cranial irradiation (PCI) in small cell lung cancer (SCLC) with surgical resection has not been fully identified. This study undertook to assess the factors affecting the risk of brain metastases in patients with stage I-III SCLC after surgical resection. The implications of PCI treatment for these patients are discussed. Methods and Materials: One hundred twenty-six patients treated with surgical resection for stage I-III SCLC from January 1998-December 2009 were retrospectively analyzed to elucidate the risk factors of brain metastases. Log-rank test and Cox regression model were used to determine the risk factors of brain metastases. Results: The median survival time for this patient population was 34 months, and the 5-year overall survival rate was 34.9%. For the whole group, 23.0% (29/126) of the patients had evidence of metastases to brain. Pathologic stage not only correlated with overall survival but also significantly affected the risk of brain metastases. The 5-year survival rates for patients with pathologic stages I, II, and III were 54.8%, 35.6%, and 14.1%, respectively (P=.001). The frequency of brain metastases in patients with pathologic stages I, II, and III were 6.25% (2/32), 28.2% (11/39), and 29.1% (16/55) (P=.026), respectively. A significant difference in brain metastases between patients with complete resection and incomplete resection was also observed (20.5% vs 42.9%, P=.028). The frequency of brain metastases was not found to be correlated with age, sex, pathologic type, induction chemotherapy, adjuvant chemotherapy, or adjuvant radiation therapy. Conclusions: Stage I SCLC patients with complete resection had a low incidence of brain metastases and a favorable survival rate. Stage II-III disease had a higher incidence of brain metastases. Thus, PCI might have a role for stage II-III disease but not for stage I disease.

Purpose: Concerns have been raised about the potential for worse treatment outcomes because of dosimetric inaccuracies related to tumor motion and increased toxicity caused by the spread of low-dose radiation to normal tissues in patients with locally advanced non-small cell lung cancer (NSCLC) treated with intensity modulated radiation therapy (IMRT). We therefore performed a population-based comparative effectiveness analysis of IMRT, conventional 3-dimensional conformal radiation therapy (3D-CRT), and 2-dimensional radiation therapy (2D-RT) in stage III NSCLC. Methods and Materials: We used the Surveillance, Epidemiology, and End Results (SEER)-Medicare database to identify a cohort of patients diagnosed with stage III NSCLC from 2002 to 2009 treated with IMRT, 3D-CRT, or 2D-RT. Using Cox regression and propensity score matching, we compared survival and toxicities of these treatments. Results: The proportion of patients treated with IMRT increased from 2% in 2002 to 25% in 2009, and the use of 2D-RT decreased from 32% to 3%. In univariate analysis, IMRT was associated with improved overall survival (OS) (hazard ratio [HR] 0.90, P=.02) and cancer-specific survival (CSS) (HR 0.89, P=.02). After controlling for confounders, IMRT was associated with similar OS (HR 0.94, P=.23) and CSS (HR 0.94, P=.28) compared with 3D-CRT. Both techniques had superior OS compared with 2D-RT. IMRT was associated with similar toxicity risks on multivariate analysis compared with 3D-CRT. Propensity score matched model results were similar to those from adjusted models. Conclusions: In this population-based analysis, IMRT for stage III NSCLC was associated with similar OS and CSS and maintained similar toxicity risks compared with 3D-CRT.

The advent of the 8th edition of the lung cancer staging system reflects a further meticulous evidence-based advance in the stratification of the survival of patients with lung cancer. Although addressing many limitations of earlier staging systems, several limitations in staging remain. This article reviews from a radiological perspective the limitations of the current staging system, highlighting the process of TNM restructuring, the residual issues with regards to the assignment of T, N, M descriptors, and their associated stage groupings and how these dilemmas impact guidance of multidisciplinary teams taking care of patients with lung cancer.

Lung cancer remains the leading cause of cancer-related mortality worldwide. Stage III non-small cell lung cancer (NSCLC) includes heterogeneous presentation of the disease including lymph node involvement and large tumour volumes with infiltration of the mediastinum, heart or spine. In the treatment of stage III NSCLC an interdisciplinary approach including radiotherapy is considered standard of care with acceptable toxicity and improved clinical outcome concerning local control. Furthermore, gross tumour volume (GTV) changes during definitive radiotherapy would allow for adaptive replanning which offers normal tissue sparing and dose escalation. A literature review was conducted to describe the predictive value of GTV changes during definitive radiotherapy especially focussing on overall survival. The literature search was conducted in a two-step review process using PubMed registered /Medline registered with the key words ''stage III non-small cell lung cancer'' and ''radiotherapy'' and ''tumour volume'' and ''prognostic factors''. After final consideration 17, 14 and 9 studies with a total of 2516, 784 and 639 patients on predictive impact of GTV, GTV changes and its impact on overall survival, respectively, for definitive radiotherapy for stage III NSCLC were included in this review. Initial GTV is an important prognostic factor for overall survival in several studies, but the time of evaluation and the value of histology need to be further investigated. GTV changes during RT differ widely, optimal timing for re-evaluation of GTV and their predictive value for prognosis needs to be clarified. The prognostic value of GTV changes is unclear due to varying study qualities, re-evaluation time and conflicting results. The main findings were that the clinical impact of GTV changes during definitive radiotherapy is still unclear due to heterogeneous study designs with varying quality

Objective: To evaluate the therapeutic efficacy and treatment-related toxicity of stereotactic body radiation therapy (SBRT) in patients with medically inoperable stage I/II non-small cell lung cancer (NSCLC). Methods: SBRT was applied to 30 patients, including clinically staged T 1 , T 2 (≤5 cm) or T 3 (chest wall primary tumors only), N 0 , M 0 ,biopsy-confirmed NSCLC. All patients were precluded from lobotomy because of physical condition or comorbidity. No patients developed tumors of any T-stage in the proximal zone. SBRT was performed with the total dose of 50 Gy to 70 Gy in 10 - 11 fractions during 12 - 15 days. prescription line was set onthe edge of the PTV. Results: The follow-up rate was 100%. The number of patients who completed the 1-, and 2-year follow-up were 15, and 10, respectively. All 30 patients completed therapy as planned. The complete response (CR), partial response (PR) and stable disease (SD) rates were 37%, 53% and 3%, respectively. With a median follow-up of 16 months (range, 4-36 months), Kaplan-Meier local control at 2 years was 94%. The 2-year overall survival was 84% and the 2-year cancer specific survival was 90%. Seven patients(23%) developed Grade 2 pneumonitis, no grade > 2 acute or late lung toxicity was observed. No one developed chest wall pain. Conclusions: It is feasible to deliver 50 Gy to 70 Gy of SBRT in 10 - 11 fractions for medically inoperable patients with stage I / II NSCLC. It was associated with low incidence of toxicities and provided sustained local tumor control.The preliminary investigation indicated the cancer specific survival probability of SBRT was high. It is necessary to perform similar investigation in a larger number of patients with long-term follow-up. (authors)

Between 1976 and 1992, 32 patients aged 75 and older with stage I-II non-small cell lung cancer (NSCLC) were given definitive radiation therapy. These patients did not undergo surgery because of old age, poor cardiac/pulmonary condition, or refusal to give consent. The mean age was 79 years, and 11 patients were over 80 years old. The histologic type was squamous cell carcinoma in 25 patients and adenocarcinoma in 7. The clinical T and N stage was T1N0 in 4 patients, T2N0 in 9, and T2N0 in 19. The total dose of radiation therapy given to each patient exceeded 60 Gy using 10-MV X-rays. The treatment was completed in all 32 patients without treatment-related complications. The 2- and 5-year overall actuarial survival rates were 40% and 16%, respectively. Eleven intercurrent deaths occurred, including 7 patients who died of heart disease. The 2- and 5-year cause-specific survival rates were 57% and 36%, respectively. None of the patients developed severe pneumonitis requiring hospitalization. All but three patients received radiation therapy on an inpatient basis. The mean duration of the hospital stay for initial treatment was 56 days, and mean ratio to total survival period (mean 739 days) was 8%. Although many elderly patients have concurrent medical complications such as heart disease and chronic pulmonary disease, the present study showed that elderly patients with clinical stage I-II NSCLC can expert a realistic probability of long-term survival with definitive radiation therapy.

The standard treatment of unresectable stage III non-small cell lung cancer is concurrent chemoradiotherapy in patients in good general condition, but where the optimal chemotherapeutic regimen has not been determined. Patients with unresectable stage III non-small cell lung cancer received nedaplatin (80 mg/m 2 ) and paclitaxel on day 1 every 4 weeks for 3-4 cycles and concurrent thoracic radiotherapy (60 Gy/30 fractions for 6 weeks) starting on day 1. The dose of paclitaxel was escalated from 120 mg/m 2 in level 1, 135 mg/m 2 in level 2 to 150 mg/m 2 in level 3. A total of 18 patients (14 males and 4 females, with a median age of 62.5 years) were evaluated in this study. Full cycles of chemotherapy were administered in 83% of patients in level 1, and in 50% of patients in levels 2 and 3. No more than 50% of patients developed grade 4 neutropenia. Transient grade 3 esophagitis and infection were noted in one patient, and unacceptable pneumonitis was noted in three (17%) patients, two of whom died of the toxicity. Dose-limiting toxicity (DLT), evaluated in 15 patients, noted in one of the six patients in level 1, three of the six patients in level 2 and one of the three patients in level 3. One DLT at level 2 developed later as radiation pneumonitis. Thus, the maximum tolerated dose was determined to be level 1. The overall response rate (95% confidence interval) was 67% (41-87%) with 12 partial responses. The doses of paclitaxel and nedaplatin could not be escalated as a result of severe pulmonary toxicity.

Serum carcinoembryonic antigen (CEA) and serum squamous cell carcinoma antigen (SCC Ag) levels have been reported to be useful as prognostic factors, indicators of clinical response, and predictors for recurrence in patients with lung cancer treated by surgery or chemotherapy. We investigated whether pretreatment serum CEA and SCC Ag levels were useful as independent prognostic factors in patients with stage I to III non-small cell lung cancer who were treated with radiation therapy alone. The serum CEA and SCC Ag levels were measured in 158 and 47 patients, respectively, before radiation therapy. Serum CEA and SCC Ag levels were measured by sandwich radioimmunoassay using the CEA-RIA (radioimmunoassay) kit and the SCC-RIA kit. Serum CEA and SCC Ag levels were above reference values in 19% and 30% of the patients, respectively. The 5-year survival rates were significantly better for patients with a negative SCC Ag result than for those with positive SCC Ag levels (p=0.0001), though no significant difference in survival rates was seen by CEA positivity (p=0.25). SCC Ag positivity (p=0.0006) and stage (p=0.04) were the important prognostic factors, as determined by multivariate analyses. Pretreatment serum SCC Ag level may be useful as an independent prognostic factor in patients with stage I to III non-small cell lung cancer who are treated with radiation therapy alone. (author)

Purpose: To explore the influence of interfraction interval in hyperfractionated radiotherapy (HFX RT) with or without concurrent chemotherapy for Stage III nonsmall cell lung cancer. Methods and Materials: One hundred sixty-nine patients treated in a randomized study were retrospectively analyzed. Group I patients were treated by HFX RT with 1.2 Gy twice daily with a total dose of 64.8 Gy in 27 treatment days, while Groups II and III patients were treated by the same HFX RT and concurrent chemotherapy with carboplatin and etoposide (every week in Group II and every other week in Group III). Interfraction intervals of either 4.5-5 h or 5.5-6 h were used for each patient. Results: Patients treated with shorter interfraction intervals (4.5-5 h) had a better prognosis than those treated with longer intervals (5.5-6 h) (median survival: 22 vs. 7 months; 5-year survival rate: 27% vs. 0%, p = 0.00000). This phenomenon was observed in all treatment groups. Patients ≥ 60 years of age, with Stage IIIA disease, or with previous weight loss ≤ 5% were treated more often with the shorter intervals than those 5%, respectively, but in all of these subgroups of patients, the shorter intervals were associated with a better prognosis. Multivariate analysis showed that the interfraction interval was an independent prognostic factor, together with sex, age, performance status, and stage. The shorter intervals were associated with an increased incidence of acute high grade toxicity, but not with an increase in late toxicity. Conclusion: Patients treated with shorter interfraction intervals (4.5-5 h) appeared to have a better survival than those treated with longer intervals (5.5-6 h). Prospective randomized studies are warranted to further investigate the influence of interfraction interval in HFX RT

Purpose: To study the effects of radiation dose, chemotherapy, and their interaction in patients with unresectable or medically inoperable Stage III non-small-cell lung cancer (NSCLC). Methods and Materials: A total of 237 consecutive Stage III NSCLC patients were evaluated. Median follow-up was 69.0 months. Patients were treated with radiation therapy (RT) alone (n = 106), sequential chemoradiation (n = 69), or concurrent chemoradiation (n = 62). The primary endpoint was overall survival (OS). Radiation dose ranged from 30 to 102.9 Gy (median 60 Gy), corresponding to a bioequivalent dose (BED) of 39 to 124.5 Gy (median 72 Gy). Results: The median OS of the entire cohort was 12.6 months, and 2- and 5-year survival rates were 22.4% and 10.0%, respectively. Multivariable Cox regression model demonstrated that Karnofsky performance status (p = 0.020), weight loss < 5% (p = 0.017), chemotherapy (yes vs. no), sequence of chemoradiation (sequential vs. concurrent; p < 0.001), and BED (p < 0.001) were significant predictors of OS. For patients treated with RT alone, sequential chemoradiation, and concurrent chemoradiation, median survival was 7.4, 14.9, and 15.8 months, and 5-year OS was 3.3%, 7.5%, and 19.4%, respectively (p < 0.001). The effect of higher radiation doses on survival was independent of whether chemotherapy was given. Conclusion: Radiation dose and use of chemotherapy are independent predictors of OS in Stage III NSCLC, and concurrent chemoradiation is associated with the best survival. There is no interaction between RT dose and chemotherapy.

Lung cancer study group at Asan Medical Center has conducted the second prospective study to determine the efficacy and feasibility of MVP chemotherapy with concurrent hyperfractionated radiotherapy for patients with stage III unresectable non-small cell lung cancer(NSCLC). All eligible patients with stage III unresectable NSCLC were treated with hyperfractionated radiotherapy( 120 cGy/fx BID, 6480 cGY/54fx) and concurrent 2 cycles of MVP(Motomycin C 6 mg/m 2 , d2 and d29, Vinblastin 6 mg/m 2 , d2 and d29, Cisplatin 6 mg/m 2 , d1 and d28) chemotherapy. Between Aug. 1993 and Nov. 1994, 62 patients entered this study ; 6(10%) had advanced stage IIIa and 56(90%) had IIIb disease including 1 with pleural effusion and 10 with supraclavicular metastases. Among 62 Patients, 48(77%) completed planned therapy. Fourteen patients refused further treatment during chemoradiotherapy. Of 46 patients evaluable for response, 34(74%) showed major response including 10(22%) with complete and 24(52%) with partial responses. Of 48 patients evaluable for toxicity, 13(27%) showed grade IV hematologic toxicity but treatment delay did not exceed 5 days. Two patients died of sepsis during chemoradiotherapy. Server weight(more than 10%) occurred in 9 patients(19%) during treatment. Nine patients(19%) developed radiation pneumonitis. Six of these patients had grad I(mild) pneumonitis with radiographic changes within the treatment fields. Three other patients had grade II pneumonitis, but none of theses patients had continuous symptoms after steroid treatment. Concurrent chemoradiotherapy for patients with advanced NSCLC was well tolerated with acceptable toxicity and achieved higher response rates than the first study, but rather low compliance rate(7%) in this study is worrisome. We need to improve nutritional support during treatment and to use G-CSF to improve leukopenia and if necessary, supportive care will given as in patients. Longer follow-up and larger sample size is needed to

The prognosis of stage III non-small cell lung cancer (NSCLC) can be improved by a combination of radiotherapy (RT) and chemotherapy (CT). In this study, the GOTHA group evaluated the feasibility, tolerance, tumour response, pattern of failure and effect on survival of a combination alternating accelerated hyperfractionated (AH) RT and CT in patients with tumour stage III NSCLC. Toxic effects were leucopenia, nausea and vomiting, mucositis, diarrhoea, alopecia and peripheral neuropathy. Alternating CT and AHRT, as used in this study, were well tolerated and allowed full dose delivery within less than 12 weeks. Initial response was not predictive of survival. The survival curve is encouraging and the 5 year survival is superior to the 5% generally observed with conventionally fractionated radiotherapy. (author).

Non-small cell lung cancer (NSCLC) is the most common lung cancer, accounting for approximately 80% to 85% of all cases. For patients with localised NSCLC (stages I to III), it has been speculated that immunotherapy may be helpful for reducing postoperative recurrence rates, or improving the clinical outcomes of current treatment for unresectable tumours. While several new agents have now entered phase III clinical trials, we felt a systematic review was needed to address the question of the effectiveness and safety of immunotherapy in patients with stages I to III NSCLC. To evaluate the effectiveness and safety of immunotherapy (excluding checkpoint inhibitors) in patients with localised NSCLC (stages I to III) who received surgery or radiotherapy with curative intent. We searched the following databases (from inception to 20 January 2017): CENTRAL, MEDLINE, Embase, and CINAHL, and five trial registers. We also manually checked abstracts or reports from relevant conference proceedings and the reference lists of included trials. We searched for randomised controlled trials (RCTs) in adults (≥ 18 years) with histologically-confirmed early-stage (stages I to III) NSCLC after surgical resection, and those with unresectable locally advanced stage III NSCLC who had received radiotherapy with curative intent. For patients who had received primary surgical treatment, postoperative radiotherapy or chemoradiotherapy was allowed if it was used for both experimental and control groups. Two review authors independently selected eligible trials, assessed risk of bias, and extracted data. We used survival analysis to pool time-to-event data, expressing the intervention effect as a hazard ratio (HR). We calculated risk ratios (RR) for dichotomous data, and mean differences for continuous data, with 95% confidence intervals (CI). Due to clinical heterogeneity (immunotherapeutic agents with different underlying mechanisms), we used random-effects models for our meta-analyses. We

Primary lung cancer is the leading cause of cancer mortality in the world. Thorough clinical staging of patients with lung cancer is important, because therapeutic options and management are to a considerable degree dependent on stage at presentation. Radiologic imaging is an essential component of clinical staging, including chest radiography in some cases, computed tomography, MRI, and PET. Multiplanar imaging modalities allow assessment of features that are important for surgical, oncologic, and radiation therapy planning, including size of the primary tumor, location and relationship to normal anatomic structures in the thorax, and existence of nodal and/or metastatic disease.

Purpose: Radiotherapy (RT) planning for breast cancer using lung density correction improves dose homogeneity. Its use obviates the need for a medial wedge, thus reducing scatter to the opposite breast. Although lung density correction is used at many centers in planning for early-stage breast cancer, long-term results of local control and survival have not been reported. Since 1984, we have used lung density correction for dose calculations at the University of Michigan. We now present our 10-year and 15-year results. Methods and Materials: The records of 867 patients with Stage I/II breast cancer treated with breast-conserving surgery and RT with or without systemic therapy were reviewed. Tangential fields delivering 45-50 Gy to the whole breast calculated using lung density correction were used. A boost was added in 96.8% of patients for a total median dose of 61.8 Gy. Results: With a median follow-up of 6.6 years (range, 0.2-18.9 years), 5-, 10-, and 15-year actuarial rates of in-breast tumor recurrence as only first failure were 2.2%, 3.6%, and 5.4%, respectively. With surgical salvage, the 15-year cumulative rate of local control was 99.7%. Factors that significantly predicted for increased rate of local recurrence in multivariate analysis were age ≤ 35 years, hazard ratio 4.8 (95% confidence interval [CI], 1.6-13.9) p = 0.004; negative progesterone receptor status, hazard ratio 6.8 (95% CI, 2.3-20.3) p = < 0.001; negative estrogen receptor status, hazard ratio 4.0 (95% CI, 1.5-11.1) p = 0.007; and lack of adjuvant tamoxifen therapy, hazard ratio 7.7 (95% CI, 1.7-33.3) p = 0.008. Relapse-free survival rates at 5, 10, and 15 years were 84.6%, 70.8%, and 55.9%, respectively; breast cancer-specific survival rates were 94.4%, 90.5%, and 86.9%, respectively; and corresponding estimates for overall survival were 89.7%, 75.7%, and 61.3%. Conclusions: Use of lung density correction was associated with high rates of local control, relapse-free survival, breast

Purpose: To determine the influence of measured comorbidity in Radiation Therapy Oncology Group (RTOG) combined modality therapy (CMT) study enrollment in Stage III non-small cell lung cancer (NSCLC). Methods and Materials: One hundred and seventy-one patients with a Karnofsky Performance Score ≥70 and clinical Stage III NSCLC were analyzed retrospectively for comorbidity, RTOG study eligibility, and enrollment at initial consultation. Effect of comorbidity scores (Cumulative Illness Rating Scale) were tested on patient selection for CMT, RTOG enrollment, and overall survival. Results: Comorbidity (Grade 4; p 2, p = 0.001), and weight loss (>5%, p = 0.001). Thirty-three patients (19%) were enrolled in a CMT RTOG study (Group 1). Forty-nine patients (29%) were eligible but not enrolled (Group 2), and 57 (33%) were ineligible (Group 3). The most common ineligibility reasons were weight loss (67%) and comorbidity in the exclusion criteria of the RTOG studies (63%). Group 1 patients were the youngest (p = 0.02), with the lowest comorbidity scores (p 2; p = 0.006) and age (≥70; p = 0.05) were independent factors influencing RTOG study enrollment in patients meeting study eligibility requirements (Groups 1 and 2). Conclusions: Comorbidity scales could be useful in stratification of patients in advanced lung cancer trials and interpretation of results particularly regarding the elderly population.

The standard treatment for stage III non-small-cell lung cancer (NSCLC) is still 60 Gy in conventional fractions combined with concurrent chemotherapy; however, the resulting local controls are disappointing. The aim of this study was to compare and assess the feasibility and efficacy of hypofractionated chemoradiotherapy using helical tomotherapy (HT) with conventional fractionation as opposed to using three-dimensional conformal radiotherapy (3D-CRT) for stage III NSCLC. Sixty-nine patients with stage III (AJCC 7th edition) NSCLC who underwent definitive radiation treatment at our institution between July 2011 and November 2013 were reviewed and analyzed retrospectively. A dose of 60 Gy in 20 fractions was delivered in the HT group (n=34), whereas 60 Gy in 30 fractions in the 3D-CRT group (n=35). Primary endpoints were toxicity, overall response rate, overall survival (OS) and progression-free survival (PFS). The median follow-up period was 26.4 months. V20 (P=0.005), V30 (P=0.001), V40 (P=0.004), mean lung dose (P=0.000) and max dose of spinal cord (P=0.005) were significantly lower in the HT group than in the 3D-CRT group. There was no significant difference in the incidences of acute radiation pneumonitis (RP) ≥ grade 2 between the two groups, whereas the incidences of acute radiation esophagitis ≥ grade 2 were significantly lower in the HT group than in the 3D-CRT group (P=0.027). Two-year overall response rate was significantly higher in the HT group than in the 3D-CRT group (P=0.015). One- and 2-year OS rates were significantly higher in the HT group (95.0% and 68.7%, respectively) than in the 3D-CRT group (85.5% and 47.6%, respectively; P=0.0236). One- and 2-year PFS rates were significantly higher in the HT group (57.8% and 26.3%, respectively) than in the 3D-CRT group (32.7% and 11.4%, respectively; P=0.0351). Univariate analysis indicated that performance status (PS), T stage and radiotherapy technique were significant prognostic factors for both OS

Full Text Available Purpose: Stage III non-small cell lung cancer (NSCLC patients with poor performance status (PS or co-morbidities are often not candidates for standard chemoradiotherapy (chemoRT due to poor tolerance to treatments. A pilot study for poor-risk stage III NSCLC patients was conducted combining cetuximab, a chimeric monoclonal antibody targeting epidermal growth factor receptor (EGFR, with chest radiation (RT. Methods: Stage III NSCLC patients with Zubrod PS 2, or Zubrod PS 0-1 with poor pulmonary function and co-morbidities prohibiting chemoRT were eligible. A loading dose of cetuximab (400 mg/m2 was delivered week one, followed by weekly cetuximab (250 mg/m2/RT to 64.5 Gy in 1.8 Gy daily fractions, and maintenance weekly cetuximab (250 mg/m2 for two years or until disease progression. H-score for EGFR protein expression was conducted in available tumors.Results: Twenty-four patients were enrolled. Twenty two were assessed for outcome and toxicity. Median survival was 14 months and median progression-free survival was 8 months. The response rate was 47% and disease control rate was 74%. Toxicity assessment revealed 22.7% overall ≥ Grade 3 non-hematologic toxicities. Grade 3 esophagitis was observed in one patient (5%. The skin reactions were mostly Grade 1 or 2 except two of 22 (9% had Grade 3 acne and 1/22 (5% had Grade 3 radiation skin burn. Grade 3-4 hypomagnesemia was seen in 4 (18% patients. One patient (5% had elevated cardiac troponin and pulmonary emboli. H-score did not reveal prognostic significance. An initially planned second cohort of the study did not commence due to slow accrual, which would have added weekly docetaxel to cetuximab/RT after completion of the first cohort of patients. Conclusions: Concurrent weekly cetuximab/chest RT followed by maintenance cetuximab for poor-risk stage III NSCLC was well tolerated. Further studies with larger sample sizes will be useful to establish the optimal therapeutic ratio of this regimen.

Definitive chemoradiotherapy is a core treatment modality for patients with stage III non-small cell lung cancer (NSCLC). Although radiotherapy (RT) technologies have advanced dramatically, to the authors' knowledge relatively little is known regarding the importance of irradiation technique on outcome, particularly given the competing risk of distant metastasis. The National Cancer Data Base was used to determine predictors of overall survival (OS) in patients with AJCC stage III NSCLC who were treated with chemoradiotherapy, focusing on the importance of conformal RT (CRT). Patients with stage III NSCLC who were treated with chemoradiotherapy between 2003 and 2005 in the National Cancer Data Base were included. RT technique was defined as conventional, 3-dimensional-conformal, or intensity-modulated RT (IMRT), the latter 2 combined as CRT. Cox proportional hazards regression was performed for univariable and multivariable analyses of OS. The median, 3-year, and 5-year survival outcomes for the 13,292 patients were 12.9 months, 19%, and 11%, respectively. The 3-year and 5-year survival probabilities of patients receiving CRT versus no CRT were 22% versus 19% and 14% versus 11%, respectively (P < .0001). On multivariable analysis, CRT was found to be significantly associated with improved OS (hazards ratio, 0.89). This effect was confirmed on sensitivity analyses, including restricting the cohort to minimum 6-month survivors, young patients with stage IIIA disease, and propensity score-matching. Institutional academic status and patient volume were not found to be associated with OS. CRT was found to be independently associated with a survival advantage. These results reflect the importance of optimal locoregional therapy in patients with stage III NSCLC and provide motivation for further study of advanced RT technologies in patients with NSCLC. © 2014 American Cancer Society.

Purpose: The objective of this study was to evaluate the efficacy and safety of Endostar combined with concurrent chemoradiotherapy (CCRT) in patients with stage III non-small-cell lung cancer (NSCLC). Methods: Patients with unresectable stage III NSCLC were treated with Endostar (7.5 mg/m 2 /d) for 7 days at weeks 1, 3, 5, and 7, while two cycles of docetaxel (65 mg/m 2 ) and cisplatin (65 mg/m 2 ) were administered on days 8 and 36, with concurrent thoracic radiation to a dose of 60–66 Gy. Primary end points were short-term efficacy and treatment-related toxicity. Results: Fifty patients were enrolled into the study, and 48 were assessable. Of the 48 patients, 83% had stage IIIB and 65% had N3 disease. Median follow-up was 25.0 months. Overall response rate was 77%. The estimated median progression-free survival (PFS) was 9.9 months, and the estimated median overall survival (OS) was 24.0 months. The 1-, 2-, and 3-year local control rates were 75%, 67%, and 51%, PFS rates were 48%, 27%, and 16%, and OS rates were 81%, 50%, and 30%, respectively. All toxicities were tolerable with proper treatment. Conclusions: The combination of Endostar with CCRT for locally advanced NSCLC patients was feasible and showed promising survival and local control rates

Purpose: The clinical benefits and risks of dose escalation (DE) for stage III non–small-cell lung cancer (NSCLC) remain uncertain despite the results from Radiation Therapy Oncology Group (RTOG) protocol 0617. There is significant heterogeneity of practice, with many clinicians prescribing intermediate dose levels between the 0617 study arms of 60 and 74 Gy. This study investigated whether this strategy is associated with any survival benefits/risks by analyzing a large multi-institutional database. Methods and Materials: An individual patient database of stage III NSCLC patients treated with radical intent concurrent chemoradiation therapy was created (13 institutions, n=1274 patients). Patients were divided into 2 groups based on tumor Biological Effective Dose at 10 Gy (BED 10): those receiving standard dose (SD; n=552), consisting of 72Gy ≤ BED 10 ≤ 76.8 Gy (eg 60-64 Gy/30-32 fractions [fr]), and those receiving intermediate dose (ID; n=497), consisting of 76.8Gy < BED 10 < 100.8 Gy (eg >64 Gy/32 fr and <74 Gy/37 fr), with lower-dose patients (n=225) excluded from consideration. Patients were then matched using propensity scores, leading to 2 matched groups of 196 patients. Outcomes were compared using various statistics including interquartile range (IQR), Kaplan-Meier curves, and adjusted Cox regression analysis. Results: Matched groups were found to be balanced except for N stage (more N3 disease in SD), median treatment year (SD in 2003; ID in 2007), platinum and taxane chemotherapy (SD in 28%; ID in 39%), and median follow-up (SD were 89 months; ID were 40 months). Median dose fractionation was 60 Gy/30 fr in SD (BED 10 IQR: 72.0-75.5 Gy) and 66 Gy/33 fr (BED 10 IQR: 78.6-79.2 Gy) in ID. Survival curves for SD and ID matched cohorts were statistically similar (P=.27); however, a nonstatistically significant trend toward better survival for ID was observed after 15 months (median survival SD: 19.3 months; ID: 21.0�

Purpose/Objective: This phase II study has been conducted to determine the feasibility, toxicity, response rate, local control, distant metastasis, and survival of hyperfractionated 3D conformal radiotherapy and concurrent chemotherapy with mitomycin C, vinblastine, and cisplatin in unresectable stage III non-small cell lung cancer (NSCLC), and also to find the most ideal 3D conformal radiotherapy technique. Materials and Methods: From Aug 1993, 173 patients with unresectable stage III NSCLC were entered into this trial and 146 (84%) completed the treatment. Hyperfractionated radiotherapy was given to a total dose of 65-70 Gy (120 cGy/fx, bid) with concurrent 2 cycles of MVP chemotherapy (Mitomycin C 6 mg/m 2 d2 and d29, Vinblastine 6 mg/m 2 d2 and d29, Cisplatin 60 mg/m 2 d1 and d28). Of these 146 patients who completed the treatment, 78 received noncoplanar 3D conformal radiotherapy using 4-6 fields and 17 received coplanar segmented conformal radiotherapy. Clinical tumor response was assessed one month after the completion of radiotherapy by computerized tomography (CT) scan. Toxicity was graded by RTOG and SWOG criteria. Normal tissue complication probability (NTCP) for lung was calculated to find the correlation with radiation pneumonitis. Results: Nineteen (13%) had stage IIIa and 127 (87%) had IIIb disease including 16 with pleural effusion and 20 with supraclavicular lymph node metastases. Response rate was 74%, including 20% complete response and 54% partial response. With a minimum follow up of 12 months, overall survival was 60% at 1 year, 30% at 2 years and median survival was 15 months. Patients achieving a complete response (n=29) had a 2-year overall survival of 46.5% compared to 28.7% for partial responders (n=79) (p=.001). Actuarial local control was 66.7% at 1 year and 43.7% at 2 years. Actuarial distant free survival was 52.3% at 1 year and 39.8% at 2 years. Major hematologic toxicity (Gr 3-4) occurred in 33% of the patients but treatment delay

Circulating tumor cell (CTC) counts are an established prognostic marker in metastatic prostate, breast and colorectal cancer, and recent data suggest a similar role in late stage non-small cell lung cancer (NSCLC). However, due to sensitivity constraints in current enrichment-based CTC detection technologies, there are few published data about CTC prevalence rates and morphologic heterogeneity in early-stage NSCLC, or the correlation of CTCs with disease progression and their usability for clinical staging. We investigated CTC counts, morphology and aggregation in early stage, locally advanced and metastatic NSCLC patients by using a fluid-phase biopsy approach that identifies CTCs without relying on surface-receptor-based enrichment and presents them in sufficiently high definition (HD) to satisfy diagnostic pathology image quality requirements. HD-CTCs were analyzed in blood samples from 78 chemotherapy-naïve NSCLC patients. 73% of the total population had a positive HD-CTC count (>0 CTC in 1 mL of blood) with a median of 4.4 HD-CTCs mL −1 (range 0–515.6) and a mean of 44.7 (±95.2) HD-CTCs mL −1 . No significant difference in the medians of HD-CTC counts was detected between stage IV (n = 31, range 0–178.2), stage III (n = 34, range 0–515.6) and stages I/II (n = 13, range 0–442.3). Furthermore, HD-CTCs exhibited a uniformity in terms of molecular and physical characteristics such as fluorescent cytokeratin intensity, nuclear size, frequency of apoptosis and aggregate formation across the spectrum of staging. Our results demonstrate that despite stringent morphologic inclusion criteria for the definition of HD-CTCs, the HD-CTC assay shows high sensitivity in the detection and characterization of both early- and late-stage lung cancer CTCs. Extensive studies are warranted to investigate the prognostic value of CTC profiling in early-stage lung cancer. This finding has implications for the design of extensive studies examining screening, therapy and

Lung cancer mortality remains high even after successful resection. Adjuvant treatment benefits stage II and III patients, but not stage I patients, and most studies fail to predict recurrence in stage I patients. Our study included 211 lung adenocarcinoma patients (stages I-IIIA; 81% stage I) who received curative resections at Taipei Veterans General Hospital between January 2001 and December 2012. We generated a prediction model using 153 samples, with validation using an additional 58 clinical outcome-blinded samples. Gene expression profiles were generated using formalin-fixed, paraffin-embedded tissue samples and microarrays. Data analysis was performed using a supervised clustering method. The prediction model generated from mixed stage samples successfully separated patients at high vs. low risk for recurrence. The validation tests hazard ratio (HR = 4.38) was similar to that of the training tests (HR = 4.53), indicating a robust training process. Our prediction model successfully distinguished high- from low-risk stage IA and IB patients, with a difference in 5-year disease-free survival between high- and low-risk patients of 42% for stage IA and 45% for stage IB ( p model for identifying lung adenocarcinoma patients at high risk for recurrence who may benefit from adjuvant therapy. Our prediction performance of the difference in disease free survival between high risk and low risk groups demonstrates more than two fold improvement over earlier published results.

Full Text Available Abstract Background There is increasing evidence that the existence of systemic inflammation response is correlated with poor prognosis in several solid tumors. The aim of this retrospective study was to investigate the association between systemic immune-inflammation index (SII and therapy response and overall survival in patients with stage III non-small cell lung cancer (NSCLC. The prognostic values of neutrophil to lymphocyte ratio (NLR, platelet to lymphocyte ratio (PLR, and prognostic nutritional index (PNI were also evaluated. Methods In total, 332 patients with new diagnosis of stage III NSCLC were included in this retrospective analysis. SII was defined as platelet counts × neutrophil counts/lymphocyte counts. Receiver operating characteristic (ROC curve was used to evaluate the optimal cut-off value for SII, NLR, PLR and PNI. Univariate and multivariate survival analysis were performed to identify the factors correlated with overall survival. Results Applying cut-offs of ≥ 660 (SII, ≥ 3.57 (NLR, ≥ 147 (PLR, ≤ 52.95 (PNI, SII ≥ 660 was significantly correlated with worse ECOG PS (< 0.001, higher T stage (< 0.001, advanced clinical stage (p = 0.019, and lower response rate (p = 0.018.

Objective: To evaluate the toxicity and efficacy of induction chemotherapy (ICT) followed by three-dimensional conformal radiotherapy (3DCRT) plus concurrent weekly paclitaxel for inoperable non-small cell lung cancer (NSCLC). Methods: Patients with stage III NSCLC in favorable conditions were treated with 2 to 4 cycles of carboplatin (AUC=5-6, d1) combined with paclitaxel (175 mg/m 2 , d1), then followed by weekly paclitaxel (40 mg/m 2 ) and concurrent 3DCRT within 34 weeks. The prescription dose of radiotherapy was given as high as possible while total lung V 20 ≤31% and total dose of the spinal cord ≤50 Gy. Results: ICT was well tolerated. During the concurrent chemoradiotherapy,the treatment of 4 patients was ended ahead of the schedule because of severe pulmonary and cardiac toxicities; the treatment of 2 patients was delayed for 7 and 12 days because of fatigue. Leucopenia(33/56) was in grade 1-2 except 1 patient in grade 3. Lymphocytopenia was severe (54/56,42 in grade 3). Three patients developed grade 3 acute radiation-induced esophagitis, and 3 developed grade 3-4 radiation-induced pneumonitis. There was one patients each who developed grade 2,3, and 4 late esophageal damage, respectively. Nine developed grade 2 pulmonary fibrosis. The overall response rate was 69.7%. The 1-year overall survival rate was 72.3%. The 1-year local progression-free survival rate was 62.7%. Conclusions: The schedule of ICT followed by weekly paclitaxel and concurrent 3DCRT can be well tolerated by most of the favorable patients with stage III NSCLC, and the toxicity is tolerable. Results of this study are encouraging, though long-term results should be followed up. (authors)

Novel approaches of chemoradiotherapy in unresectable stage IIIA and stage IIIB non-small cell lung cancer.

Approximately one third of patients with non-small cell lung cancer have unresectable stage IIIA or stage IIIB disease, and appropriate patients are candidates for chemoradiotherapy with curative intent. The optimal treatment paradigm is currently undefined. Concurrent chemoradiotherapy, compared with sequential chemotherapy and thoracic radiation therapy (TRT), results in superior overall survival outcomes as a result of better locoregional control. Recent trials have revealed efficacy for newer chemotherapy combinations similar to that of older chemotherapy combinations with concurrent TRT and a lower rate of some toxicities. Ongoing phase III trials will determine the roles of cisplatin and pemetrexed concurrent with TRT in patients with nonsquamous histology, cetuximab, and the L-BLP25 vaccine. It is unlikely that bevacizumab will have a role in stage III disease because of its toxicity. Erlotinib, gefitinib, and crizotinib have not been evaluated in stage III patients selected based on molecular characteristics. The preliminary results of a phase III trial that compared conventionally fractionated standard-dose TRT (60 Gy) with high-dose TRT (74 Gy) revealed an inferior survival outcome among patients assigned to the high-dose arm. Hyperfractionation was investigated previously with promising results, but adoption has been limited because of logistical considerations. More recent trials have investigated hypofractionated TRT in chemoradiotherapy. Advances in tumor targeting and radiation treatment planning have made this approach more feasible and reduced the risk for normal tissue toxicity. Adaptive radiotherapy uses changes in tumor volume to adjust the TRT treatment plan during therapy, and trials using this strategy are ongoing. Ongoing trials with proton therapy will provide initial efficacy and safety data.

A phase III multi-centre randomised trial (ROSEL) has been initiated to establish the role of stereotactic radiotherapy in patients with operable stage IA lung cancer. Due to rapid changes in radiotherapy technology and evolving techniques for image-guided delivery, guidelines had to be developed in order to ensure uniformity in implementation of stereotactic radiotherapy in this multi-centre study. A Quality Assurance Working Party was formed by radiation oncologists and clinical physicists from both academic as well as non-academic hospitals that had already implemented stereotactic radiotherapy for lung cancer. A literature survey was conducted and consensus meetings were held in which both the knowledge from the literature and clinical experience were pooled. In addition, a planning study was performed in 26 stage I patients, of which 22 were stage 1A, in order to develop and evaluate the planning guidelines. Plans were optimised according to parameters adopted from RTOG trials using both an algorithm with a simple homogeneity correction (Type A) and a more advanced algorithm (Type B). Dose conformity requirements were then formulated based on these results. Based on current literature and expert experience, guidelines were formulated for this phase III study of stereotactic radiotherapy versus surgery. These guidelines can serve to facilitate the design of future multi-centre clinical trials of stereotactic radiotherapy in other patient groups and aid a more uniform implementation of this technique outside clinical trials

Full Text Available Michael R Shafique, Lary A Robinson, Scott Antonia Department of Thoracic Oncology, H Lee Moffitt Cancer Center and Research Institute, Tampa, FL, USA Abstract: Lung cancer is the most common cancer worldwide and the most common cause of cancer-related death. Non-small-cell lung cancer comprises ~87% of newly diagnosed cases of lung cancer, and nearly one-third of these patients have stage III disease. Despite improvements in the treatment of stage IV lung cancer, particularly with the introduction and dissemination of checkpoint inhibitors, very little progress has been made in the treatment of stage III lung cancer. In this article, we discuss the general staging criteria and treatment options for stage III lung cancer. We review how concurrent radiation and chemotherapy can have immunomodulatory effects, supporting the rationale for incorporating immunotherapy into existing treatment paradigms. Finally, we discuss the results of the PACIFIC trial and implications for the treatment of stage III lung cancer. In the PACIFIC trial, adding durvalumab as a maintenance therapy following the completion of chemoradiotherapy improved progression-free survival in patients with locally advanced unresectable stage III lung cancer. On the strength of these results, durvalumab has been approved by the US Food and Drug Administration for use in this setting, representing the first advance in the treatment of stage III lung cancer in nearly a decade.

This study aims to report 100 pediatric patients of empyema thoracis treated by open decortication, highlighting the presentation, delay in referral, operative findings, the response to surgical intervention, and follow-up. All the children who underwent open decortication for stage III empyema thoracis during the study period January 2015-December 2016 were included. Preoperative workup included hemogram, serum protein, chest radiographs, and contrast-enhanced computed tomographic (CECT) scan of the chest. One hundred (65 males, 35 females) (age 2 months-13 years, mean 4.5 years) were operated during a 2-year period. Among them, 90% patients were referred 3 weeks after the onset of disease. Intercostal chest drainage (ICD) had been inserted in (95) 95% cases. Thickened pleura, multiloculated pus, and lung involvement were invariably seen on CECT scan. Bronchopleural fistula was present in five patients. Decortication and removal of necrotic tissue were performed in all the patients. Mean duration of postoperative ICD was 4 days. Follow-up ranged from 1 month to 2 years (mean 12 months). There was no mortality. Five patients had proven tuberculosis. Only 10% presented within the early period of the disease. The duration of the disease had a direct relationship with the thickness of the pleura and injury to the underlying lung. Delayed referral causes irreversible changes in the lung prolonging recovery. Meticulous open surgical debridement gives gratifying results. The status of the lung at the end of surgery is a major prognostic factor.

Technical studies suggest that computed tomography (CT) -based simulation improves the therapeutic ratio for thoracic radiation therapy (TRT), although few studies have evaluated its use or impact on outcomes. We used the Surveillance, Epidemiology and End Results (SEER) -Medicare linked data to identify CT-based simulation for TRT among Medicare beneficiaries diagnosed with stage III non-small-cell lung cancer (NSCLC) between 2000 and 2005. Demographic and clinical factors associated with use of CT simulation were identified, and the impact of CT simulation on survival was analyzed by using Cox models and propensity score analysis. The proportion of patients treated with TRT who had CT simulation increased from 2.4% in 1994 to 34.0% in 2000 to 77.6% in 2005. Of the 5,540 patients treated with TRT from 2000 to 2005, 60.1% had CT simulation. Geographic variation was seen in rates of CT simulation, with lower rates in rural areas and in the South and West compared with those in the Northeast and Midwest. Patients treated with chemotherapy were more likely to have CT simulation (65.2% v 51.2%; adjusted odds ratio, 1.67; 95% CI, 1.48 to 1.88; P simulation. Controlling for demographic and clinical characteristics, CT simulation was associated with lower risk of death (adjusted hazard ratio, 0.77; 95% CI, 0.73 to 0.82; P simulation. CT-based simulation has been widely, although not uniformly, adopted for the treatment of stage III NSCLC and is associated with higher survival among patients receiving TRT.

Our goal was to develop a nomogram by exploiting intratumour heterogeneity on CT and PET images from routine 18 F-FDG PET/CT acquisitions to identify patients with the poorest prognosis. This retrospective study included 116 patients with NSCLC stage I, II or III and with staging 18 F-FDG PET/CT imaging. Primary tumour volumes were delineated using the FLAB algorithm and 3D Slicer trademark on PET and CT images, respectively. PET and CT heterogeneities were quantified using texture analysis. The reproducibility of the CT features was assessed on a separate test-retest dataset. The stratification power of the PET/CT features was evaluated using the Kaplan-Meier method and the log-rank test. The best standard metric (functional volume) was combined with the least redundant and most prognostic PET/CT heterogeneity features to build the nomogram. PET entropy and CT zone percentage had the highest complementary values with clinical stage and functional volume. The nomogram improved stratification amongst patients with stage II and III disease, allowing identification of patients with the poorest prognosis (clinical stage III, large tumour volume, high PET heterogeneity and low CT heterogeneity). Intratumour heterogeneity quantified using textural features on both CT and PET images from routine staging 18 F-FDG PET/CT acquisitions can be used to create a nomogram with higher stratification power than staging alone.

The objective of this study was to identify any gender differences in the outcomes of concurrent platinum-based chemotherapy and thoracic radiotherapy for unresectable stage III non-small cell lung cancer (NSCLC). A comparative retrospective review of the clinical characteristics and treatment outcomes between female and male NSCLC patients receiving chemoradiotherapy. Of a total of 204 patients, 44 (22%) were females and 160 (78%) were males. There was no difference in age, body weight loss, performance status or disease stage between the sexes, whereas never-smokers and adenocarcinoma were more common in female patients (55% vs. 3%, P 80% of the patients, respectively, of both sexes. Grade 3-4 neutropenia was observed in 64% of the female patients and 63% of the male patients. Severe esophagitis was encountered in <10% of the patients, irrespective of the sex. The response rate was higher in the female than in the male patients (93% vs. 79%, P=0.028), but the median progression-free survival did not differ between the sexes. The median survival time in the female and male patients was 22.3 and 24.3 months, respectively (P=0.64). This study failed to show any gender differences in the survival or toxicity among patients treated by concurrent chemoradiotherapy. These results contrast with the better survival in female patients undergoing surgery for localized disease or chemotherapy for metastatic disease. (author)

Although several computer-aided computed tomography (CT) analysis methods have been reported to objectively assess the disease severity and progression of idiopathic pulmonary fibrosis (IPF), it is unclear which method is most practical. A universal severity classification system has not yet been adopted for IPF. The purpose of this study was to test the correlation between quantitative-CT indices and lung physiology variables and to determine the ability of such indices to predict disease severity in IPF. A total of 27 IPF patients showing radiological UIP pattern on high-resolution (HR) CT were retrospectively enrolled. Staging of IPF was performed according to two classification systems: the Japanese and GAP (gender, age, and physiology) staging systems. CT images were assessed using a commercially available CT imaging analysis workstation, and the whole-lung mean CT value (MCT), the normally attenuated lung volume as defined from -950 HU to -701 Hounsfield unit (NL), the volume of the whole lung (WL), and the percentage of NL to WL (NL%), were calculated. CT indices (MCT, WL, and NL) closely correlated with lung physiology variables. Among them, NL strongly correlated with forced vital capacity (FVC) (r = 0.92, P <0.0001). NL% showed a large area under the receiver operating characteristic curve for detecting patients in the moderate or advanced stages of IPF. Multivariable logistic regression analyses showed that NL% is significantly more useful than the percentages of predicted FVC and predicted diffusing capacity of the lungs for carbon monoxide (Japanese stage II/III/IV [odds ratio, 0.73; 95% confidence intervals (CI), 0.48 to 0.92; P < 0.01]; III/IV [odds ratio. 0.80; 95% CI 0.59 to 0.96; P < 0.01]; GAP stage II/III [odds ratio, 0.79; 95% CI, 0.56 to 0.97; P < 0.05]). The measurement of NL% by threshold-based volumetric CT analysis may help improve IPF staging.

Purpose: To determine the prognostic role of comorbidity in Stage III non-small cell lung cancer (NSCLC) treated definitively with radiotherapy alone. Methods and Materials: A total of 112 patients with clinical Stage III NSCLC (American Joint Commission on Cancer 1997) enrolled in four Radiation Therapy Oncology Group studies (83-11, 84-03, 84-07, and 88-08 nonchemotherapy arms) at a single institution were analyzed retrospectively for overall survival (OS) and comorbidity. Of the 112 patients, 105 (94%) completed their assigned radiotherapy. The median assigned dose was 50.4 Gy to the lymphatics (range 45-50.4 Gy) and 70.2 Gy to the primary tumor (range 60-79.2 Gy). Comorbidity was rated retrospectively using the Cumulative Illness Rating Scale for Geriatrics (CIRS-G) and Charlson scales. Karnofsky performance scores (KPSs) and weight loss were prospectively recorded. Because only 8 patients had a KPS of 70). Results: The median survival was 10.39 months (range 7.87-12.91). The 2-, 3-, and 5-year OS rate was 20.5%, 12.5%, and 7.1%, respectively. On univariate analysis, clinical stage (IIIA vs. IIIB) was found to be a statistically significant factor influencing OS (p=0.026), and the histologic features, grade, tumor size as measured on CT scans, age, tobacco use, weight loss ≥5%, and total dose delivered to the primary tumor were not. A KPS of ≤70 (p=0.001), the presence of a CIRS-G score of 4 (extremely severe; p=0.0002), and a severity index of >2 (p 2 were independently associated with inferior OS; clinical tumor stage was not found to be an independent prognostic factor. Conclusion: KPS and comorbidity are important independent prognostic factors in Stage III NSCLC. Comorbidity should be included in protocols studying advanced stage NSCLC and used for stratification

This study aim to determine whether serum 25(OH D levels are related to lung functions, physical performance and balance in patients with chronic obstructive pulmonary disease (COPD. Methods: in 90 patients with COPD and 57 healthy controls lung function tests, physical performance tests (time up and go, gait velocity test, sit-to-stand test, isometric strength, isokinetic strength, static (functional reach test and dynamic (time up and go balance tests and the association of 25(OHD levels with lung functions, physical performance and balance were evaluated. Results: the COPD patients had significantly more deficit in physical function and balance parameters, and in dynamic balance test (p<0.005. Isokinetic knee muscle strength (flexor and extensor in COPD patients was significantly lower than in the controls (p<0.05; FEV1 (p=0.008, FVC (p=0.02, FEV1/FVC (p=0.04, TLC (p=0.01 were lower in COPD patients with vitamin D deficiency [25(OH D less than 15ng/mL] than in COPD patients without vitamin D deficiency. Hand grip test (p=0.000 and isokinetic knee muscle strength (flexor and extensor (p<0.05 were also lower in COPD patients with vitamin D deficiency. Vitamin D deficiency was more pronounced in patients with stage III COPD (p<0.05. Conclusion: patients with COPD had worst physical functioning, poor balance and less muscle strength. Severe disturbed lung and peripheral muscle functions are more pronounced in COPD patients with vitamin D deficiency.

Methods and Materials: Between January 1988 and June 1993, a total of 58 patients entered a phase II study. Carboplatin (400 mg/m 2 ) was given intravenously on days 1 and 29, and etoposide (50 mg/m 2 ) was given orally on days 1-21 and 29-42. Accelerated hyperfractionated radiotherapy was administered starting on day 1, with a total dose of 51 Gy in 34 fractions over 3.5 weeks. Results: In 55 evaluable patients, the complete response rate was 27% and the overall response rate was 65%. For the 55 patients, the median survival time was 10 months, and the 1-, 2-, and 5-year survival rates were 45%, 24%, and 9.1%, respectively. The median time until relapse was 8 months and the 1-, 2-, and 5-year relapse-free survival rates were 45%, 20%, and 9.1%, respectively. The median time to local recurrence was 14 months and the 5-year local control rate was 13%; the median time to distant metastasis was 18 months and the 5-year distant metastasis-free rate was 15%. Hematological, esophageal, and bronchopulmonary acute grade 3 or 4 toxicities were observed in 22%, 7%, and 4% of the patients, respectively. There was no grade 5 toxicity or late grade ≥ 3 toxicity. Conclusion: Concurrent accelerated hyperfractionated radiotherapy and carboplatin/oral etoposide produced relatively low and acceptable toxicity. The survival results appeared to be comparable to those obtained in nonelderly patients with stage III non-small-cell lung cancer treated by full-dose radiation

Full Text Available Background and objective Increased macrophage inhibitory cytokine-1 (MIC-1, member of transforming growth factor-β (TGF-β superfamily, was found in patients serum with epithelial tumors. Therefore, our aim was to delineate the diagnostic and prognostic value of serum MIC-1 in patients with stage I-II non-small cell lung cancer (NSCLC. Methods A total of 152 consecutive patients with stage I–II NSCLC were prospectively enrolled and underwent follow up after total resection of tumor. Serum MIC-1 level was detected in lung cancer patients by ELISA, 48 benign pulmonary disease patients and 105 healthy controls, and was correlated with clinical features and prognosis of patients. Results The level of MIC-1 of NSCLC patients was significantly higher than that of controls (P<0.001 and benign pulmonary disease patients (P<0.001. A threshold of 1,000 pg/mL could be used to diagnose early-stage NSCLC with 70.4% sensitivity and 99.0% specificity. The level of MIC-1 was associated with elder age (P=0.001, female (P=0.03 and T2 (P=0.022. A threshold of 1,465 pg/mL could identify patients with early poor outcome with 72.2% sensitivity and 66.1% specificity. The overall 3-year survival rate in patients with high level of MIC-1 (≥1,465 pg/mL was significantly lower than that of patients with low MIC-1 level (77.6% vs 94.8%. Multivariable Cox regression revealed that a high level of MIC-1 was an independent risk factor for compromised overall survival (HR=3.37, 95%CI: 1.09-10.42, P=0.035. Conclusion High level of serum MIC-1 could be served as a potential biomarker for diagnosis and poorer outcome in patients with early-stage NSCLC.

Primary lung cancer is the leading cause of cancer death in men in the world. Although the introduction of new drugs, new therapeutic strategies and despite therapeutic advances, the prognosis is relatively improved during the last years. To evaluate the prognosis of patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC) and to identify prognostic factors at these stages. A retrospective study, including 140 cases of locally advanced or metastatic NSCLC diagnosed in our department between 2003 and 2013. The average age was 61±10 years (35 to 90 years). Sex ratio was 18. The delays management were 80±25 days for presentation, 45±20 days for the diagnostic, while the treatment delay was 8±2.33 days. The cancer was at stage IIIA in 14%, IIIB in 27% and IV in 59%. Six months and one-year survival was between 50 and 74% and between 9 and 25%, respectively. Better survival was observed in patients with NSCLC on stage III, having better performance status, having comorbid conditions, with prolonged delays management, a short therapeutic delay and patients who received specific antitumor treatment. The prognostic factors in locally advanced and metastatic NSCLC in our patients were: stage of cancer, performance status, comorbid conditions, delay of management and specific antitumoral treatment. These factors should be considered in the management of patients with advanced NSCLC. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

How to use CT and PET-CT rationally to raise diagnosis, staging and prognostic assessment of lung cancer to a higher level at the best cost-effect ratio is a subject that Chinese clinicians and radiologists should face conscientiously. We review the rational application of CT and PET-CT in four aspects of lung cancer, including screening and detection, morphologic evaluation, haemodynamic or metabolic feature evaluation, and follow-up, staging and prognostic evaluation. As PET-CT is only available in class III-A hospitals today, CT is the most popular equipment in China. PET-CT is more valuable only in cases where CT presentation of lung cancer is atypical or difficult to determine, or in cases where the diagnosis of lung cancer has been initially confirmed, for which clinical staging and decision concerning on therapeutic regimens are needed. We also recommend the current strategies of CT and PET-CT managing of SPN in China. (orig.)

There are no reliable blood biomarkers to detect early lung cancer. We used a novel strategy that allows discovery of differentially present proteins against a complex and variable background. Mass spectrometry analyses of paired pulmonary venous-radial arterial blood from 16 lung cancer patients were applied to identify plasma proteins potentially derived from the tumor microenvironment. Two differentially expressed proteins were confirmed in 64 paired venous-arterial blood samples using an immunoassay. Twenty-eight pre- and postsurgical resection peripheral blood samples and two independent, blinded sets of plasma from 149 participants in a lung cancer screening study (49 lung cancers and 100 controls) and 266 participants from the National Heart Lung and Blood Institute Lung Health Study (45 lung cancer and 221 matched controls) determined the accuracy of the two protein markers to detect subclinical lung cancer. Connective tissue-activating peptide III (CTAP III)/ neutrophil activating protein-2 (NAP-2) and haptoglobin were identified to be significantly higher in venous than in arterial blood. CTAP III/NAP-2 levels decreased after tumor resection (P = .01). In two independent population cohorts, CTAP III/NAP-2 was significantly associated with lung cancer and improved the accuracy of a lung cancer risk prediction model that included age, smoking, lung function (FEV(1)), and an interaction term between FEV(1) and CTAP III/NAP-2 (area under the curve, 0.84; 95% CI, 0.77 to 0.91) compared to CAPIII/NAP-2 alone. We identified CTAP III/NAP-2 as a novel biomarker to detect preclinical lung cancer. The study underscores the importance of applying blood biomarkers as part of a multimodal lung cancer risk prediction model instead of as stand-alone tests.

Purpose The significance of radiotherapy (RT) –associated cardiac injury for stage III non–small-cell lung cancer (NSCLC) is unclear, but higher heart doses were associated with worse overall survival in the Radiation Therapy Oncology Group (RTOG) 0617 study. We assessed the impact of heart dose in patients treated at our institution on several prospective dose-escalation trials. Patients and Methods From 1996 to 2009, 127 patients with stage III NSCLC (Eastern Cooperative Oncology Group performance status, 0 to 1) received dose-escalated RT to 70 to 90 Gy (median, 74 Gy) in six trials. RT plans and cardiac doses were reviewed. Records were reviewed for the primary end point: symptomatic cardiac events (symptomatic pericardial effusion, acute coronary syndrome, pericarditis, significant arrhythmia, and heart failure). Cardiac risk was assessed by noting baseline coronary artery disease and calculating the WHO/International Society of Hypertension score. Competing risks analysis was used. Results In all, 112 patients were analyzed. Median follow-up for surviving patients was 8.8 years. Twenty-six patients (23%) had one or more events at a median of 26 months to first event (effusion [n = 7], myocardial infarction [n = 5], unstable angina [n = 3], pericarditis [n = 2], arrhythmia [n = 12], and heart failure [n = 1]). Heart doses (eg, heart mean dose; hazard ratio, 1.03/Gy; P = .002,), coronary artery disease (P < .001), and WHO/International Society of Hypertension score (P = .04) were associated with events on univariable analysis. Heart doses remained significant on multivariable analysis that accounted for baseline risk. Two-year competing risk–adjusted event rates for patients with heart mean dose < 10 Gy, 10 to 20 Gy, or ≥ 20 Gy were 4%, 7%, and 21%, respectively. Heart doses were not associated with overall survival. Conclusion Cardiac events were relatively common after high-dose thoracic RT and were independently associated with both heart dose and

Purpose: To investigate the impact of setup and range uncertainties, breathing motion, and interplay effects using scanning pencil beams in robustly optimized intensity modulated proton therapy (IMPT) for stage III non-small cell lung cancer (NSCLC). Methods and Materials: Three-field IMPT plans were created using a minimax robust optimization technique for 10 NSCLC patients. The plans accounted for 5- or 7-mm setup errors with ±3% range uncertainties. The robustness of the IMPT nominal plans was evaluated considering (1) isotropic 5-mm setup errors with ±3% range uncertainties; (2) breathing motion; (3) interplay effects; and (4) a combination of items 1 and 2. The plans were calculated using 4-dimensional and average intensity projection computed tomography images. The target coverage (TC, volume receiving 95% of prescribed dose) and homogeneity index (D{sub 2} − D{sub 98}, where D{sub 2} and D{sub 98} are the least doses received by 2% and 98% of the volume) for the internal clinical target volume, and dose indexes for lung, esophagus, heart and spinal cord were compared with that of clinical volumetric modulated arc therapy plans. Results: The TC and homogeneity index for all plans were within clinical limits when considering the breathing motion and interplay effects independently. The setup and range uncertainties had a larger effect when considering their combined effect. The TC decreased to <98% (clinical threshold) in 3 of 10 patients for robust 5-mm evaluations. However, the TC remained >98% for robust 7-mm evaluations for all patients. The organ at risk dose parameters did not significantly vary between the respective robust 5-mm and robust 7-mm evaluations for the 4 error types. Compared with the volumetric modulated arc therapy plans, the IMPT plans showed better target homogeneity and mean lung and heart dose parameters reduced by about 40% and 60%, respectively. Conclusions: In robustly optimized IMPT for stage III NSCLC, the setup and range

Full Text Available Abstract Background Although evaluation of at least 12 lymph nodes (LNs is recommended as the minimum number of nodes required for accurate staging of colon cancer patients, there is disagreement on what constitutes an adequate identification of such LNs. Methods To evaluate the minimum number of LNs for adequate staging of Stage II and III colon cancer, 490 patients were categorized into groups based on 1-6, 7-11, 12-19, and ≥ 20 LNs collected. Results For patients with Stage II or III disease, examination of 12 LNs was not significantly associated with recurrence or mortality. For Stage II (HR = 0.33; 95% CI, 0.12-0.91, but not for Stage III patients (HR = 1.59; 95% CI, 0.54-4.64, examination of ≥20 LNs was associated with a reduced risk of recurrence within 2 years. However, examination of ≥20 LNs had a 55% (Stage II, HR = 0.45; 95% CI, 0.23-0.87 and a 31% (Stage III, HR = 0.69; 95% CI, 0.38-1.26 decreased risk of mortality, respectively. For each six additional LNs examined from Stage III patients, there was a 19% increased probability of finding a positive LN (parameter estimate = 0.18510, p Conclusions Thus, the 12 LN cut-off point cannot be supported as requisite in determining adequate staging of colon cancer based on current data. However, a minimum of 6 LNs should be examined for adequate staging of Stage II and III colon cancer patients.

We previously showed that different pathologic subtypes were associated with different prognostic values in patients with stage IA lung adenocarcinoma (AC). We hypothesize that differential gene expression profiles of different subtypes may be valuable factors for prognosis in stage IA lung adenocarcinoma. We performed microarray gene expression profiling on tumor tissues micro-dissected from patients with acinar and solid predominant subtypes of stage IA lung adenocarcinoma. These patients had undergone a lobectomy and mediastinal lymph node dissection at the Shanghai Chest Hospital, Shanghai, China in 2012. No patient had preoperative treatment. We performed the Gene Set Enrichment Analysis (GSEA) analysis to look for gene expression signatures associated with tumor subtypes. The histologic subtypes of all patients were classified according to the 2015 WHO lung Adenocarcinoma classification. We found that patients with the solid predominant subtype are enriched for genes involved in RNA polymerase activity as well as inactivation of the p53 pathway. Further, we identified a list of genes that may serve as prognostic markers for stage IA lung adenocarcinoma. Validation in the TCGA database shows that these genes are correlated with survival, suggesting that they are novel prognostic factors for stage IA lung adenocarcinoma. In conclusion, we have uncovered novel prognostic factors for stage IA lung adenocarcinoma using gene expression profiling in combination with histopathology subtyping.

To evaluate the effect of MVP chemotherapy and hyperfractionated radiotherapy in Stage III unresectable non small cell lung cancer (NSCLC), authors have conducted a prospective randomized study since January 1991. Stage IIIa or IIIb unresectable NSCLC patients were treated with hyperfractionated radiotherapy (120 cGy/fx BID) up to 6500 cGY following 3 cycles of induction MVP (Mitomycin C 6 mg/m 2 , vinblastine 6 mg/m 2 , Cisplatin 60 mg/m 2 ) and randomized for either observation or 3 cycles of maintenance MVP chemotherapy. Until August 1991, 18 patients were registered to this study. 4 cases were stage IIIa and 14 were stage IIIb. Among 18 cases 2 were lost after 2 cycles of chemotherapy, and 16 were analyzed for this preliminary report. The response rate of induction chemotherapy was 62.5%; partial response, 50% and minimal response, 12.5%. Residual tumor of the one partial responder was completely disappeared after radiotherapy. Among 6 cases who were progressed during induction chemotherapy, 4 of them were also progressed after radiotherapy. All patients were tolerated BID radiotherapy without definite increase of acute complications, compared with conventional radiotherapy group. But at the time of this report, one patient expired in two month after the completion of the radiotherapy because of treatment related complication. Although the longer follow up is needed, authors are encouraged with higher response rate and acceptable toxicity of this treatment. Authors believe that this study is worthwhile to continue

Nowadays, comprehensive treatment, including surgery, chemotherapy and radiotherapy is advocated for stage III non-small cell lung cancer (NSCLC). However, many researchers have questioned the effectiveness of surgery. The aim of this study is to evaluate the effect of surgery for stage III NSCLC. Between March 2002 and October 2012, 310 cases that have completed followed-up data with stage III NSCLC were received in the Peking Union Medical College Hospital. They were divided into surgical and non-surgical groups according to whether received surgery when diagnosed. In TNM staging, stage III NSCLC includes stage IIIa and IIIb, and stage IIIa NSCLC can be grouped into stage T4N0/T3-4N1M0 and T1-3N2M0 according to different N stages. Analyzed the enumeration data by Chi-Square test. Kaplan-Meier survival method was used to calculate the overall survival (OS) and progression-free survival (PFS), and to draw the survival curves. A P value less than 0.05 was evaluated as statistically significant. Three hundred and ten stage III NSCLC patients include surgical group 189 cases and non-surgical group 121 cases. One hundred and eighty-eight stage IIIa NSCLC patients include surgical group 152 cases and non-surgical group 36 cases. In stage IIIa, stage T4N0/T3-4N1M0 had 57 patients with 44 surgical and 13 non-surgical patients, and stage T1-3N2M0 had 131 patients with 108 surgical and 23 non-surgical patients. Thirty-seven out of 121 stage IIIb NSCLC patients received surgery. They had 22 stage T4N2M0 cases and 15 stage T1-4N3M0 cases. The patient whose performance status was 0 and staging was stage IIIa was more inclined to undergo surgery. For stage IIIa NSCLC patients, the median OS of surgical and non-surgical groups were 38.9 and 21.8 months, and the median PFS of them were 19.2 and 11.9 months respectively. The difference of OS between the two groups was significant (P=0.041), but the PFS of them had no significant difference (P=0.209). For stage T4N0/T3-4N1M0 which

Purpose: To determine the maximum tolerated dose in concurrent three-dimensional conformal radiotherapy (3D-CRT) with chemotherapy for unresectable Stage III non-small-cell lung cancer (NSCLC). Patients and Methods: Eligible patients with unresectable Stage III NSCLC, age {>=}20 years, performance status 0-1, percent of volume of normal lung receiving 20 GY or more (V{sub 20}) {<=}30% received three to four cycles of cisplatin (80 mg/m{sup 2} Day 1) and vinorelbine (20 mg/m{sup 2} Days 1 and 8) repeated every 4 weeks. The doses of 3D-CRT were 66 Gy, 72 Gy, and 78 Gy at dose levels 1 to 3, respectively. Results: Of the 17, 16, and 24 patients assessed for eligibility, 13 (76%), 12 (75%), and 6 (25%) were enrolled at dose levels 1 to 3, respectively. The main reasons for exclusion were V{sub 20} >30% (n = 10) and overdose to the esophagus (n = 8) and brachial plexus (n = 2). There were 26 men and 5 women, with a median age of 60 years (range, 41-75). The full planned dose of radiotherapy could be administered to all the patients. Grade 3-4 neutropenia and febrile neutropenia were noted in 24 (77%) and 5 (16%) of the 31 patients, respectively. Grade 4 infection, Grade 3 esophagitis, and Grade 3 pulmonary toxicity were noted in 1 patient, 2 patients, and 1 patient, respectively. The dose-limiting toxicity was noted in 17% of the patients at each dose level. The median survival and 3-year and 4-year survival rates were 41.9 months, 72.3%, and 49.2%, respectively. Conclusions: 72 Gy was the maximum dose that could be achieved in most patients, given the predetermined normal tissue constraints.

Nagasaka, Misako; Gadgeel, Shirish M

2018-01-01

Adjuvant platinum based chemotherapy is accepted as standard of care in stage II and III non-small cell lung cancer (NSCLC) patients and is often considered in patients with stage IB disease who have tumors ≥ 4 cm. The survival advantage is modest with approximately 5% at 5 years. Areas covered: This review article presents relevant data regarding chemotherapy use in the perioperative setting for early stage NSCLC. A literature search was performed utilizing PubMed as well as clinical trial.gov. Randomized phase III studies in this setting including adjuvant and neoadjuvant use of chemotherapy as well as ongoing trials on targeted therapy and immunotherapy are also discussed. Expert commentary: With increasing utilization of screening computed tomography scans, it is possible that the percentage of early stage NSCLC patients will increase in the coming years. Benefits of adjuvant chemotherapy in early stage NSCLC patients remain modest. There is a need to better define patients most likely to derive survival benefit from adjuvant therapy and spare patients who do not need adjuvant chemotherapy due to the toxicity of such therapy. Trials for adjuvant targeted therapy, including adjuvant EGFR-TKI trials and trials of immunotherapy drugs are ongoing and will define the role of these agents as adjuvant therapy.

Purpose: To determine whether pretreatment CT texture features can improve patient risk stratification beyond conventional prognostic factors (CPFs) in stage III non-small cell lung cancer (NSCLC). Methods and Materials: We retrospectively reviewed 91 cases with stage III NSCLC treated with definitive chemoradiation therapy. All patients underwent pretreatment diagnostic contrast enhanced computed tomography (CE-CT) followed by 4-dimensional CT (4D-CT) for treatment simulation. We used the average-CT and expiratory (T50-CT) images from the 4D-CT along with the CE-CT for texture extraction. Histogram, gradient, co-occurrence, gray tone difference, and filtration-based techniques were used for texture feature extraction. Penalized Cox regression implementing cross-validation was used for covariate selection and modeling. Models incorporating texture features from the 33 image types and CPFs were compared to those with models incorporating CPFs alone for overall survival (OS), local-regional control (LRC), and freedom from distant metastases (FFDM). Predictive Kaplan-Meier curves were generated using leave-one-out cross-validation. Patients were stratified based on whether their predicted outcome was above or below the median. Reproducibility of texture features was evaluated using test-retest scans from independent patients and quantified using concordance correlation coefficients (CCC). We compared models incorporating the reproducibility seen on test-retest scans to our original models and determined the classification reproducibility. Results: Models incorporating both texture features and CPFs demonstrated a significant improvement in risk stratification compared to models using CPFs alone for OS (P=.046), LRC (P=.01), and FFDM (P=.005). The average CCCs were 0.89, 0.91, and 0.67 for texture features extracted from the average-CT, T50-CT, and CE-CT, respectively. Incorporating reproducibility within our models yielded 80.4% (±3.7% SD), 78.3% (±4.0% SD), and 78

Purpose: To determine whether pretreatment CT texture features can improve patient risk stratification beyond conventional prognostic factors (CPFs) in stage III non-small cell lung cancer (NSCLC). Methods and Materials: We retrospectively reviewed 91 cases with stage III NSCLC treated with definitive chemoradiation therapy. All patients underwent pretreatment diagnostic contrast enhanced computed tomography (CE-CT) followed by 4-dimensional CT (4D-CT) for treatment simulation. We used the average-CT and expiratory (T50-CT) images from the 4D-CT along with the CE-CT for texture extraction. Histogram, gradient, co-occurrence, gray tone difference, and filtration-based techniques were used for texture feature extraction. Penalized Cox regression implementing cross-validation was used for covariate selection and modeling. Models incorporating texture features from the 33 image types and CPFs were compared to those with models incorporating CPFs alone for overall survival (OS), local-regional control (LRC), and freedom from distant metastases (FFDM). Predictive Kaplan-Meier curves were generated using leave-one-out cross-validation. Patients were stratified based on whether their predicted outcome was above or below the median.

Concurrent chemoradiotherapy (CCRT) has become the standard of care for patients with unresectable stage III non–small cell lung cancer (NSCLC). The comparative merits of two widely used regimens: carboplatin/paclitaxel (PC) and cisplatin/etoposide (PE), each with concurrent radiotherapy, remain largely undefined. Records for consecutive patients with stage III NSCLC treated with PC or PE and ≥60 Gy chest radiotherapy between 2000 and 2011 were reviewed for outcomes and toxicity. Survival was estimated using the Kaplan–Meier method and Cox modeling with the Wald test. Comparison across groups was done using the student's t and chi-squared tests. Seventy-five (PC: 44, PE: 31) patients were analyzed. PC patients were older (median 71 vs. 63 years; P = 0.0006). Other characteristics were comparable between groups. With PE, there was significantly increased grade ≥3 neutropenia (39% vs. 14%, P = 0.024) and thrombocytopenia (10% vs. 0%, P = 0.039). Radiation pneumonitis was more common with PC (66% vs. 38%, P = 0.033). Five treatment-related deaths occurred (PC: 3 vs. PE: 2, P = 1.000). With a median follow-up of 51.6 months, there were no significant differences in relapse-free survival (median PC 12.0 vs. PE 11.5 months, P = 0.700) or overall survival (median PC 20.7 vs. PE 13.7 months; P = 0.989). In multivariate analyses, no factors predicted for improved survival for either regimen. PC was more likely to be used in elderly patients. Despite this, PC resulted in significantly less hematological toxicity but achieved similar survival outcomes as PE. PC is an acceptable CCRT regimen, especially in older patients with multiple comorbidities

The treatment results of 152 non-operated lung cancer patients were analyzed. Median survival times (MST; months) for all patients based on the stage (UICC'87) were 28 M (n=12) for stage I, 18 M (n=16) for stage II, 8 M (n=58) for stage III A, 6 M (n=46) for stage III B, and 4 M (n=20) for stage IV. The effect of combined radiochemotherapy was quite evident in small cell lung cancer (SCLC) patients. Here, the MST of the radiotherapy alone group (n=11) was 5 M, whereas that of radiochemotherapy group (n=14) was 12 M (p<0.05). In non-small cell lung cancer (NSCLC), the effect of radiochemotherapy was recognized only in stage III A and III B patients. In this case, the MST of the radiotherapy alone group (n=50) was 6 M, whereas that of the radiochemotherapy group (n=38) was 9 M (p<0.05). The duration of time from the initial therapy to the occurrence of distant metastasis in stage III A and III B patients was longer in the radiochemotherapy group than in the radiotherapy alone group (p<0.05). As for the metastatic sites, a delay in the occurrence of brain, lung and pleural metastasis was also recognized in the radiochemotherapy group (p<0.05). In this retrospective study, the value of combined radiochemotherapy was evident in SCLC and stage III-NSCLC patients. However, there was considerable case to case variation in the dosage, combination of agents and timing of chemotherapy. Recently, more aggressive chemotherapy is now being applied. (author)

Full Text Available Background and objective Nowadays, comprehensive treatment, including surgery, chemotherapy and radiotherapy is advocated for stage III non-small cell lung cancer (NSCLC. However, many researchers have questioned the effectiveness of surgery. The aim of this study is to evaluate the effect of surgery for stage III NSCLC. Methods Between March 2002 and October 2012, 310 cases that have completed followed-up data with stage III NSCLC were received in the Peking Union Medical College Hospital. They were divided into surgical and non-surgical groups according to whether received surgery when diagnosed. In TNM staging, stage III NSCLC includes stage IIIa and IIIb, and stage IIIa NSCLC can be grouped into stage T4N0/T3-4N1M0 and T1-3N2M0 according to different N stages. Analyzed the enumeration data by Chi-Square test. Kaplan-Meier survival method was used to calculate the overall survival (OS and progression-free survival (PFS, and to draw the survival curves. A P value less than 0.05 was evaluated as statistically significant. Results Three hundred and ten stage III NSCLC patients include surgical group 189 cases and non-surgical group 121 cases. One hundred and eighty-eight stage IIIa NSCLC patients include surgical group 152 cases and non-surgical group 36 cases. In stage IIIa, stage T4N0/T3-4N1M0 had 57 patients with 44 surgical and 13 non-surgical patients, and stage T1-3N2M0 had 131 patients with 108 surgical and 23 non-surgical patients. Thirty-seven out of 121 stage IIIb NSCLC patients received surgery. They had 22 stage T4N2M0 cases and 15 stage T1-4N3M0 cases. The patient whose performance status was 0 and staging was stage IIIa was more inclined to undergo surgery. For stage IIIa NSCLC patients, the median OS of surgical and non-surgical groups were 38.9 and 21.8 months, and the median PFS of them were 19.2 and 11.9 months respectively. The difference of OS between the two groups was significant (P=0.041, but the PFS of them had no

Purpose: 1) To define the incidence of isolated lung events in a cohort of women treated with conservative surgery (CS) and radiation therapy (RT) for early stage breast cancer. 2) Among such patients, to define the relative distribution of primary lung cancer, metastatic breast cancer, and indeterminate lesions; and to identify any predictors for a diagnosis of lung vs metastatic breast cancer. 3) To examine the cohort with respect to whether a higher than expected incidence of lung cancer is seen following breast irradiation. Materials and Methods: Between 1968 and 1986, 1865 patients with clinical stage I-II breast cancer were treated with CS and RT; the median follow-up for surviving patients is 129 months. The study population was limited to patients who developed a subsequent isolated lung event as the first site of distant disease. Isolated lung event was defined as disease limited to the thoracic cavity, without evidence of either uncontrolled local breast disease or metastatic disease elsewhere. Diagnosis of the lung event as a primary lung cancer, a metastatic breast lesion, or an indeterminate lesion was documented from the viewpoint of 1) the pathologic analysis and 2) the clinical impression at the time of the lung event. Results: Sixty six of the 1865 patients (3.5%) developed an isolated lung event. The relative distribution of the pathologic and clinical diagnoses is shown below: The 66 lung events were characterized either as a solitary pulmonary nodule (27), multiple nodules (23), pleural effusion alone (10), unknown (2), or miscellaneous other findings (4). Among the 47 patients for whom pathology was available, the diagnosis remained indeterminate for 24 (51%). For patients with a definitive pathologic diagnosis, 69% ((9(13))) of smokers had a new lung cancer compared to 20% ((2(10))) of non-smokers (p=0.036), and 67% ((10(15))) of patients with a solitary pulmonary nodule had lung cancer compared to 14% ((1(7))) for other lung presentations (p

Purpose: To explore once-weekly stereotactic body radiotherapy (SBRT) in nonoperable patients with localized, locally advanced, or metastatic lung cancer. Methods and Materials: A total of 102 primary (89 untreated plus 13 recurrent) and 7 metastatic tumors were studied. The median follow-up was 38 months, the average patient age was 75 years. Of the 109 tumors studied, 60 were Stage I (45 IA and 15 IB), 9 were Stage II, 30 were Stage III, 3 were Stage IV, and 7 were metastases. SBRT only was given in 73% (40 Gy in four fractions to the planning target volume to a total dose of 53 Gy to the isocenter for a biologically effective dose of 120 Gy 10 ). SBRT was given as a boost in 27% (22.5 Gy in three fractions once weekly for a dose of 32 Gy at the isocenter) after 45 Gy in 25 fractions to the primary plus the mediastinum. The total biologically effective dose was 120 Gy 10 . Respiration gating was used in 46%. Results: The overall response rate was 75%; 33% had a complete response. The overall response rate was 89% for Stage IA patients (40% had a complete response). The local control rate was 82%; it was 100% and 93% for Stage IA and IB patients, respectively. The failure rate was 37%, with 17% within the planning target volume. No Grade 3-4 acute toxicities developed in any patient; 12% and 7% of patients developed Grade 1 and 2 toxicities, respectively. Late toxicity, all Grade 2, developed in 3% of patients. The 5-year cause-specific survival rate for Stage I was 70% and was 74% and 64% for Stage IA and IB patients, respectively. The 3-year Stage III cause-specific survival rate was 30%. The patients with metastatic lung cancer had a 57% response rate, a 27% complete response rate, an 86% local control rate, a median survival time of 19 months, and 23% 3-year survival rate. Conclusions: SBRT is noninvasive, convenient, fast, and economically attractive; it achieves results similar to surgery for early or metastatic lung cancer patients who are older

To understand and mitigate the onset of Stage III corrosion of multicomponent oxides waste glasses. Stage III refers to a resumption of the high initial rate of glass dissolution in some glass samples that have otherwise exhibited dissolution at the much lower residual rate for a long time (Stage II). Although the onset of Stage III is known to occur concurrently with the precipitation of particular alteration products, the root cause of the transition is still unknown. Certain glass compositions (notably AFCI) and high pH environmental conditions are also associated with this observed transition.

Lung cancer and pulmonary tuberculosis (TB) comorbidity is a clinical problem that presents a challenge for the diagnosis and treatment of both diseases. To clarify the clinical and survival characteristics of cases with both lung cancer and active pulmonary TB. From 2008 to 2013, 3350 TB patients admitted to the TB Department of the Chest Diseases Hospital of Izmir, Turkey, were evaluated. In 38 (1.1%) male patients, lung cancer and TB were found to coexist. Almost all of the patients were diagnosed at Stage III (n = 14, 36.8%) or IV (n = 17, 44.7%) lung cancer, whereas four (10.6%) had Stage II and three (7.9%) had Stage I disease. Squamous cell lung cancer was the predominant histology (n = 23, 60.7%). The median overall survival among patients was 13.4 months (95%CI 8.09-18.8). One-year survival rates for patients with Stages I, II, III and IV were respectively 100%, 75%, 57% and 40%. The present study demonstrates that lung cancer combined with active pulmonary TB most frequently presents as squamous cell carcinoma, with a male predominance. The overall survival of lung cancer patients did not change even with concomitant active TB.

Primarily combined radiotherapy and chemotherapy are used to treat unresectable non-small-cell lung cancer; however, the results are not satisfactory. In this study treatment results were retrospectively analyzed and the prognostic factors related to survival were identified. From March 1999 to January 2004, 102 patients with stage IIIA/IIIB non-small-cell lung cancer received definitive radiotherapy with or without chemotherapy. Radiotherapy involved a daily dose of 1.8-2.0 Gy five times a week; 60 Gy was set as the total dose. Maximal chemotherapy was given to patients with normal kidney, liver, and bone marrow functions. The 5-year overall survival rate was 22.2%; the median survival was 18 months. The median follow-up of surviving patients was 53 months. The complete or partial response rate was 85%. At the time of the last follow-up, 21 patients were alive and 81 patients had died, including 5 patients who had died due to radiation pneumonitis. There were significant differences in survival and in the fatal radiation pneumonitis rate between patients with superior lobe lesions and those with middle or inferior lobe lesions. Patients whose primary tumor is located in the superior lobe appear to have a better clinical outcome.

Elderly patients with non-small cell lung cancer (NSCLC) are frequently treated with radiation therapy (RT) alone, due to poor performance status or underlying disease. We investigated the effectiveness of RT over 60 Gy administered alone to NSCLC patients who were unfit or rejecting for combination treatment. From April 2002 to July 2010, 83 patients with stage II-III NSCLC, aged over 60 years, treated by RT alone with a curative aim were analyzed. Radiation was targeted to the primary tumor and clinically involved lymph nodes. A total dose of 66 Gy in 30 fractions (2.2 Gy/fraction) was delivered once daily (5 fractions weekly). One month after completing RT, initial tumor responses were evaluated. Median age of patients was 73 years (range, 60 – 82 years). The median survival time was 18.6 months (range, 2–135). The actuarial overall survival rates at 2 and 3 years were 39 % and 23 %, and cause-specific survival rate at 2 and 3 years were 57 % and 47 %, respectively. When primary tumor was controlled, the 2- and 3-year CSS were 56 % and 45 %, but 32 % and 23 % in those patients with local failure, respectively (P = 0.017). Additionally, the local control rate was associated with the initial tumor response (P = 0.01). No patient experienced grade 4+ toxicity. For stage II-III NSCLC patients aged over 60 years and unfit or rejecting for combination treatment, RT alone showed promising result. Long-term disease control can be expected if an early tumor response to radiation is achieved, which could result in improved overall survival rates

Sputum cytology examination is the most effective method to detect early stage central type squamous cell carcinoma. As sputum-positive early stage lung cancer usually does not show any abnormal findings on chest X-ray film, fiberoptic bronchoscopy is subsequently performed for localization. However, sometimes cases do not show any abnormal findings of cancer endoscopically because they are very early stage cases. For the purpose of localization of invisible lesions the photodynamic reaction was employed in this study. Photodynamic reaction is achieved by transfer of energy of an excited photo-sensitizer induced by photoradiation of light. This phenomenon was already recognized in the beginning of this century. Study of tumor localization of the bronchial tree using hematoporphyrin derivative (HpD) and a mercury arc lamp was first performed in the Mayo Clinic in 1960s. In 1978, krypton laser was used first as a light source by Profio and Doiron. Authors have been doing research on early localization of such endoscopically occult early lung cancer since 1978. They recently developed an image processing system using an excimer dye laser for early localization of lung cancer. (author). 5 refs., 4 figs., 1 tab

We retrospectively analyzed the impact of subpleural lesions of early stage non-small cell lung cancer on the patterns of failure to support selection of postoperative adjuvant therapy. The study included 91 patients who underwent surgery for early stage non-small cell lung cancer at Donga University hospital from Dec 1990 to Sep 1996. Twenty five patients were excluded due to postoperative mortality (four patients, 4.4%) and stage III (21 patients). Of 66 patients, 22 patients were subpleural lesions (15 patients in stage I, and seven patients in stage II). Postoperative adjuvant radiation therapy was given to seven patients with T2N1 disease. The median follow-up duration was 29.5 months (range; 8-84 months). The overall survival rate was 69.5% at 3 years. For all patients who presented with (22 patients) and without (44 patients) subpleural lesions, 3-year overall survival rates were 35.5% and 84.6%, respectively (p=0.0017). For stage I patients who presented with (15 patients) and without (29 patients) subpleural lesions, 3-year overall survival rates were 33.1% and 92.3%, respectively (p=0.001). For stage II patients who presented with (7 patients) and without (15 patients) subpleural lesions, 3-year overall survival rates were 53.3% and 45.7%, respectively (p=0.911). For patients with T2NO disease (34 patients) who presented with (11 patients) and without (23 patients) subpleural lesions, 3-year overall survival rates were 27.3% and 90.3%,respectively (p=0.009).These observations suggest that the subpleural lesion play an important role as a prognostic factor for early stage non-small cell lung cancer. Especially for T2NO disease, patients with subpleural lesions showed significantly lower survival rate than those without that

Full Text Available The mitochondrial targeted DNA repair enzyme, 8-oxoguanine DNA glycosylase 1, was previously reported to protect against mitochondrial DNA (mtDNA damage and ventilator induced lung injury (VILI. In the present study we determined whether mitochondrial targeted endonuclease III (EndoIII which cleaves oxidized pyrimidines rather than purines from damaged DNA would also protect the lung. Minimal injury from 1 h ventilation at 40 cmH2O peak inflation pressure (PIP was reversed by EndoIII pretreatment. Moderate lung injury due to ventilation for 2 h at 40 cmH2O PIP produced a 25-fold increase in total extravascular albumin space, a 60% increase in W/D weight ratio, and marked increases in MIP-2 and IL-6. Oxidative mtDNA damage and decreases in the total tissue glutathione (GSH and the GSH/GSSH ratio also occurred. All of these indices of injury were attenuated by mitochondrial targeted EndoIII. Massive lung injury caused by 2 h ventilation at 50 cmH2O PIP was not attenuated by EndoIII pretreatment, but all untreated mice died prior to completing the two hour ventilation protocol, whereas all EndoIII-treated mice lived for the duration of ventilation. Thus, mitochondrial targeted DNA repair enzymes were protective against mild and moderate lung damage and they enhanced survival in the most severely injured group.

Objective: To detect cytokeratin in routine pathology negative regional lymph nodes postoperatively in non-small cell lung carcinoma (NSCLC). To investigate the relationship of lymph node micrometastasis in P-TNM stages NSCLC and survival rates. Methods: From Jan. 1996 to Dec. 2003, 107 paraffin-embedded specimens of T1-T4N0-N1M0 NSCLC patients were collected. Anti-cytokeratin(CK) antibody AE1/AE3 was applied to detect cytokeratin with Envision TM method in routine pathological negative region lymph nodes in NSCLC, and selected negative control, positive control and blank control. The pulmo- nary hilar lymph node micrometastasis was upward regulated with stage pCK-N1, mediastinal lymph node mi- crometastatsis was upward regulated with stage pCK-N2. The result applied to SPSS11.0 software to process. Results: The CK positive rate was 29.9% in all the patients. The CK positive rate was 27% (21/78), 30% (7/23), 67%(4/6)in stage p- I, p-II and p-III, respectively. All these data showed the tendency by which detectable rate increased and was accompanied by disease progress. Comparing the annual survival rate and median survival time of the non-micrometastasis group with the micrometastasis group in two groups, the survival rate difference was statistically significant. Comparing the armnal survival rate and median sur- vival time in pCK-III A stage with p- I -II stage, pCK-III A stage annual survival rate and median survival time was significantly different(P=0.020). Similarly, comparing the survival rate in pCK-II B stage with p- I B stage, pCK- II B stage survival rate was significantly different( P = 0. 059). Comparing the survival time of pCK-IIIA stage with p-III stage, pCK-II B stage, with p-II B stage, euther survival time difference was statistically significant (P=0.838, 0.518). Conclusions: The rate of positive cytokeratin increase is accompanied by the disease progress in NSCLC. Positive cytokeratin has disadvantageous prognosis. It is showed that pCK-N1 may

A majority of pediatric patients and rare adult patients with the acquired immunodeficiency syndrome (AIDS) develop a chronic respiratory disorder referred to as lymphocytic interstitial pneumonitis (LIP). Efforts to identify an infectious agent responsible for this process so far have failed. In this study, frozen sections of lungs from patients with AIDS and pulmonary disease were tested by in situ molecular hybridization for the presence of cells infected with human T-cell lymphotropic virus type III (HTLV-III) and expressing viral RNA. In the case of an infant with LIP, a relatively high frequency (0.1%) of cells in the lung were found to be positive for HTLV-III RNA. This number is the lower limit of total cells infected since the in situ hybridization technique as applied in this study depends on expression of HTLV-III genes, and previous evidence indicates that a proportion of cells infected with HTLV-III may not express viral RNA. Moreover, this degree of infection of the lung is likely limited to LIP, since in ten patients with AIDS and pulmonary diseases other than LIP, only 0% to 0.002% of cells in lung were positive for viral RNA expression. Thus, HTLV-III may play a direct causal role in the development of LIP in infected patients, implicating its involvement in yet another of the diverse clinical diseases associated with this virus

Lung transplantation is the gold standard therapy for patients with end-stage lung disease. The use of the lung allocation score (LAS) has permitted improved allocation of scarce pulmonary allografts. Recently, Crawford et al. examined the experience in the United States in lung transplantation in candidates with the highest LAS, demonstrating that outcomes for candidates with the highest LAS scores have improved significantly. This editorial places these data in the broader context of thoracic transplantation, and highlights the critical need for ongoing examination of this critically-ill patient population.

Lung cancer staging according to the TNM system is based on morphological assessment of the primary cancer, lymph nodes and metastases. All aspects of this important oncological classification are measurable with MRI. Pulmonary nodules can be detected at the clinically relevant size of 4-5 mm in diameter. The extent of mediastinal, hilar and supraclavicular lymph node affection can be assessed at the same time. The predominant metastatic spread to the adrenal glands and spine can be detected in coronal orientation during dedicated MRI of the lungs. Search focused whole body MRI completes the staging. Various additional MR imaging techniques provide further functional and clinically relevant information during a single examination. In the oncological context the most important techniques are imaging of perfusion and tumor motion. Functional MRI of the lungs complements the pure staging and improves surgical approaches and radiotherapy planning. (orig.) [de

Purpose: The purpose was to assess the feasibility and efficacy of hyperfractionated accelerated radiotherapy (HART) after induction chemotherapy for Stage III non-small-cell lung cancer. Methods and materials: Treatment consisted of 2 cycles of cisplatin 80 mg/m 2 on Day 1 and vinorelbine 25 mg/m 2 on Days 1 and 8 every 3 weeks followed by HART, 3 times a day (1.5, 1.8, 1.5 Gy, 4-h interval) for a total dose of 57.6 Gy. Results: Thirty patients were eligible. Their median age was 64 years (range, 46-73 years), 24 were male, 6 were female, 8 had performance status (PS) 0, 22 had PS 1, 9 had Stage IIIA, and 21 had Stage IIIB. All but 1 patient completed the treatment. Common grade ≥3 toxicities during the treatment included neutropenia, 25; infection, 5; esophagitis, 5; and radiation pneumonitis, 3. The overall response rate was 83%. The median survival was 24 months (95% confidence interval [CI], 13-34 months), and the 2-year overall survival was 50% (95% CI, 32-68%). The median progression-free survival was 10 months (95% CI, 8-20 months). Conclusion: Hyperfractionated accelerated radiotherapy after induction of cisplatin and vinorelbine was feasible and promising. Future investigation employing dose-intensified radiotherapy in combination with chemotherapy is needed

Objective: To analyze the clinical characteristics and prognosis of the second primary lung cancer. Methods: The interval between the second primary lung cancer and the previous primary cancer ranged from 10 days to 317 months (median 49 months). Of the 129 patients treated from 1971 to 1997 by surgery only, radiotherapy only and chemotherapy only or combined therapy, 11 (8.5%) patients had stage I, 29 (22.5%) stage II, 75 (58.1%) stage III and 14 (10.9%) stage IV; 30 patients received surgery alone, 54 radiotherapy alone, 8 chemotherapy alone, 12 surgery plus radiotherapy, 20 radiotherapy plus chemotherapy, 4 surgery plus chemotherapy and 1 surgery plus radiotherapy plus chemotherapy. Results: The overall 2-, 3- and 5-year survival rates were 40.2%, 27.2% and 15.3%. The stage I, II, III and IV 2-year survival rates were 71.6%, 60.7%, 32.9% and 0%, respectively (P 49 and ≤49 months of the interval between the second primary lung cancer and the previous primary cancer (P>0.05). Conclusions: Second primary lung cancer are similar to the first primary lung cancer in clinical characteristics and prognosis. The main cause of failure is lung cancer perse.

Purpose: To compare the diagnostic capability of PET-HCT image fusion and helical computed tomography (HCT) for nodal and distant metastases detection in patients with lung cancer. Material and methods: Between February, 2003 and March, 2004 sixty-six consecutive lung cancer patients (45 men and 21 women, mean ages: 63 years old, range: 38 to 96 years old) who underwent HCT and PET-HCT fusion imaging were evaluated retrospectively. All patients had histological confirmation of lung cancer and a definitive diagnosis established on the basis of pathology results and/or clinical follow-up. Results: For global nodal staging (hilar and mediastinal) HCT showed a sensitivity, specificity, positive predictive value and negative predictive value of 72%, 47%, 62% and 58% respectively, versus 94%, 77%, 83% and 92% corresponding to PET-HCT examination. For assessment of advanced nodal stage (N3) PET-HCT showed values of 92%, 100%, 100% and 98% respectively. For detection of distant metastasis, HCT alone had values of 67%, 93%, 84% and 83% respectively versus 100%, 98%, 96% and 100% for the PET-HCT fusion imaging. In 20 (30%) patients under-staged or over-staged on the basis of HCT results, PET-HCT allowed accurate staging. Conclusions: PET-HCT fusion imaging was more effective than HCT alone for nodal and distant metastasis detection and oncology staging. (author)

The paper compares a recent investigation of Stage-III recovery on electron-irradiated gold by Sonnenberg and Dedek with earlier work on cold-worked or quenched gold. The experimental results of Sonnenberg and Dedek are found to be in excellent agreement with those of Schuele, Seeger, Schumacher, and King, who showed that in Au Stage III is due to the migration of an elementary intrinsic point defect with migration enthalpy Hsup(III) = (0.71 +- 0.02)eV. Since the monovacancy migration enthalpy Hsub(IVsup(M)) = (0.83 +- 0.02)eV obtained by Schuele et al. has been confirmed by other workers and independent techniques, it is concluded that Hsup(III) represents the migration enthalpy of isolated self-interstitials.

Purpose: With the increasing use of conformal radiation therapy methods for non-small cell lung cancer (NSCLC), it is necessary to accurately determine respiratory-induced tumor motion. The purpose of this study is to analyze and compare the motion characteristics of early and locally advanced stage NSCLC tumors in a large population and correlate tumor motion with position, volume, and diaphragm motion. Methods and materials: A total of 191 (94 early stage, 97 locally advanced) non-small cell lung tumors were analyzed for this study. Each patient received a four-dimensional CT scan prior to receiving radiation treatment. A soft-tissue-based rigid registration algorithm was used to track the tumor motion. Tumor volumes were determined based on the gross tumor volume delineated by physicians in the end of expiration phase. Tumor motion characteristics were correlated with their standardized tumor locations, lobe location, and clinical staging. Diaphragm motion was calculated by subtracting the diaphragm location between the expiration and the inspiration phases. Results: Median, max, and 95th percentile of tumor motion for early stage tumors were 5.9 mm, 31.0 mm, and 20.0 mm, which were 1.2 mm, 12 mm, and 7 mm more than those in locally advanced NSCLC, respectively. The range of motion at 95th percentile is more than 50% larger in early stage lung cancer group than in the locally advanced lung cancer group. Early stage tumors in the lower lobe showed the largest motion with a median motion of 9.2 mm, while upper/mid-lobe tumors exhibited a median motion of 3.3 mm. Tumor volumes were not correlated with motion. Conclusion: The range of tumor motion differs depending on tumor location and staging of NSCLC. Early stage tumors are more mobile than locally advanced stage NSCLC. These factors should be considered for general motion management strategies when 4D simulation is not performed on individual basis.

Specimens doped with interstitial clusters and single vacancies have been annealed isochronally through the temperature range of stage III. Combining this annealing with a test irradiation after each annealing step reactions of mobile single test interstitials with the doping defects were studied. These reactions provide information about the variation of the doping defect structure during annealing. The experimental results suggest that vacancy clusters are formed in stage III

Currently, no satisfactory biomarkers are available to screen for lung cancer. Surface-Enhanced Laser Desorption/ionization Time-of- Flight Mass Spectrometry ProteinChip system (SELDI-TOF-MS) is one of the currently used techniques to identify biomarkers for cancers. The aim of this study is to explore the application of serum SELDI proteomic patterns to distinguish lung cancer patients from healthy individuals. A total of 208 serum samples, including 158 lung cancer patients and 50 healthy individuals, were randomly divided into a training set (including 11 sera from patients with stages I/II lung cancer, 63 from patients with stages III/IV lung cancer and 20 from healthy controls) and a blinded test set (including 43 sera from patients with stages I/II lung cancer, 41 from patients with stages III/IV lung cancer and 30 from healthy controls). All samples were analyzed by SELDI technology. The spectra were generated on weak cation exchange (WCX2) chips, and protein peaks clustering and classification analyses were made using Ciphergen Biomarker Wizard and Biomarker Pattern software, respectively. We additionally determined Cyfra21-1 and NSE in the 208 serum samples included in this study using an electrochemiluminescent immunoassay. Five protein peaks at 11493, 6429, 8245, 5335 and 2538 Da were automatically chosen as a biomarker pattern in the training set. When the SELDI marker pattern was tested with the blinded test set, it yielded a sensitivity of 86.9%, a specificity of 80.0% and a positive predictive value of 92.4%. The sensitivities provided by Cyfra21-1 and NSE used individually or in combination were significantly lower than that of the SELDI marker pattern (P < 0.005 or 0.05, respectively). Based on the results of the test set, we found that the SELDI marker pattern showed a sensitivity of 91.4% in the detection of non-small cell lung cancers (NSCLC), which was significantly higher than that in the detection of small cell lung cancers (P < 0.05); The

The aim of this study was to evaluate FDG-PET for assessment of therapy response and for prediction of patient outcome after neo-adjuvant radio-chemotherapy (NARCT) of advanced non-small cell lung cancer (NSCLC). Seventy patients with histologically proven stage III NSCLC underwent FDG-PET investigations before and after NARCT. Changes in FDG uptake and PET findings after completion of NARCT were compared with (1) the histology of tumour samples obtained at surgery or repeat mediastinoscopy, and (2) treatment results in terms of achieved operability and long-term survival. The mean average FDG uptake of the primary tumours in the patient group decreased significantly during NARCT (p = 0.004). Sensitivity, specificity and overall accuracy of FDG-PET were 94.5%, 80% and 91%, respectively, for the detection of residual viable primary tumour, and 77%, 68% and 73%, respectively, for the presence of lymph node metastases. A negative PET scan or a reduction in the standardised uptake value (SUV) of more than 80% was the best predictive factor for a favourable outcome of further treatment. Progressive disease according to PET (new tumour manifestations or increasing SUV) was significantly correlated with an unfavourable outcome (p = 0.005). In this subgroup, survival of patients who underwent surgery was not significantly different from survival among those who did not undergo surgery, whereas for the whole patient group, complete tumour resection had a significant influence on outcome. FDG-PET is suitable to assess response to NARCT in patients with stage III NSCLC accurately. It was highly predictive for treatment outcome and patient survival. PET may be helpful in improving restaging after NARCT by allowing reliable assessment of residual tumour viability. (orig.)

High-level evidence supports adjuvant radiotherapy for rectal cancer. We examined the influence of socio demographic factors on patterns of adjuvant radiotherapy for resected Stage II/III rectal cancer. Methods. Patients undergoing surgical resection for stage II/III rectal cancer were identified in SEER registry. Results. A total of 21,683 patients were identified. Majority of patients were male (58.8%), white (83%), and with stage III (54.9%) and received radiotherapy (66%). On univariate analysis, male gender, stage III, younger age, year of diagnosis, and higher socioeconomic status (SES) were associated with radiotherapy. Radiotherapy was delivered in 84.4% of patients <50; however, only 32.8% of those are >80 years. Logistic regression demonstrated a significant increase in the use of radiotherapy in younger patients who are 50 (OR, 10.3), with stage III (OR, 1.21), males (OR, 1.18), and with higher SES. Conclusions. There is a failure to conform to standard adjuvant radiotherapy in one-third of patients, and this is associated with older age, stage II, area-level of socioeconomic deprivation, and female sex.

One hundred forty-nine patients with localized nonsmall cell carcinoma of the lung (Stage III A and B) were treated with two monthly cycles of initial chemotherapy that included vindesine-cisplatin followed by 6000 cGy of thoracic irradiation. Patients with complete, partial, and minor response after initial chemotherapy were randomized into groups to receive either maintenance chemotherapy (four cycles) after radiotherapy or radiotherapy alone. The objective response rate was 24% after chemotherapy and 41% after combined chemoradiotherapy (complete response, 7.5%). The overall median survival was 9 months and the 2-year survival was 14%. Survival was identical with or without maintenance chemotherapy. The 2-year survival of patients with complete response was 75% compared with 9% for patients with partial or minor response. These results suggest that only the few patients (ten) who achieve complete response have a strong probability of survival. It is therefore essential to search for other therapeutic modalities that result in an increase of the complete response rate

We conducted a modified phase I/II trial investigating the incorporation of three-dimensional conformal thoracic radiation therapy (TCRT) into the treatment paradigm of induction and concurrent carboplatin and paclitaxel in patients with unresectable stage IIIA/B non-small cell lung cancer. Patients received 2 cycles of induction carboplatin (area under the curve of 6) and paclitaxel (225 mg/m) on days 1, and 22. On day 43 concurrent TCRT and weekly x6 of carboplatin (area under the curve = 2) and paclitaxel (45 mg/m) was initiated. The TCRT dose was escalated from 60 to 74 Gy in 4 cohorts (60, 66, 70, and 74 Gy), and the 74 Gy cohort was expanded into a phase II trial. Sixty-two patients were enrolled; the median age 57 years (range, 36-82), 39 were male (63%), 61 (98%) had a performance status of 0 or 1, 28 (45%) had stage IIIA disease, 21 (34%) had >5% weight loss, and the median forced expiratory volume 1 = 2.10 liters (range, 1.02-3.75). With a median follow-up for survivors of approximately 9 years (range, 7-11 years) the median progression-free survival, time to tumor progression, and overall survival (OS) (with 95% confidence intervals) were 10 (8.5-17), 15 (9-50), and 25 months (18-37), respectively. The 5-year progression-free survival and OS rates were 21% (12-32%) and 27% (17-39%), respectively. The 10-year OS rate was 14% (7-25%). The long term survival rate compares favorably to other treatment approaches for stage III non-small cell lung cancer.

Despite advances in treatments, lung cancer has been the leading cause of cancer-related deaths in the United States for the past several decades. Recent findings from the National Lung Screening Trial reveal that low-dose helical computed tomography (CT) scan screening of high-risk individuals reduces lung cancer mortality. This suggests that early detection is of key importance to improving patient outcome. However, of those screened with CT scans, 25% had positive scans that require further follow-up studies which often involve more radiation exposure and invasive tests to reduce false positive results. The purpose of this study was to identify candidate plasma biomarkers to aid in diagnosis of lung cancer in at-risk individuals. We found increased expression of the CXC chemokine connective tissue-activating peptide (CTAP)-III from plasma specimens of lung cancer patients compared to at-risk control subjects. Identification of the peptide was confirmed by the addition of an anti-NAP-2 antibody that recognizes CTAP-III and NAP-2. We also quantified and verified the increased levels of plasma CTAP-III with ELISA in patients with lung cancer (mean ± SD, 1859 ± 1219 ng/mL) compared to controls (698 ± 434 ng/mL; Pcancer patients. Further studies are required to determine if this chemokine could be utilized in a blood-based biomarker panel for the diagnosis of lung cancer.

Purpose: To assess the clinical applicability of a protocol evaluated in a previously reported phase II study of concurrent chemoradiotherapy followed by consolidation chemotherapy with bi-weekly docetaxel and carboplatin in patients with stage III, unresectable, non-small-cell lung cancer (NSCLC). Methods and Materials: Between January 2000 and March 2006, 116 previously untreated patients with histologically proven, stage III NSCLC were treated with concurrent chemoradiotherapy. Radiation therapy was administered in 2-Gy daily fractions to a total dose of 60 Gy in combination with docetaxel, 30 mg/m 2 , and carboplatin at an area under the curve value of 3 every 2 weeks during and after radiation therapy. Results: The median survival time for the entire group was 25.5 months. The actuarial 2-year and 5-year overall survival rates were 53% and 31%, respectively. The 3-year cause-specific survival rate was 60% in patients with stage IIIA disease, whereas it was 35% in patients with stage IIIB disease (p = 0.007). The actuarial 2-year and 5-year local control rates were 62% and 55%, respectively. Acute hematologic toxicities of Grade ≥3 severity were observed in 20.7% of patients, while radiation pneumonitis and esophagitis of Grade ≥3 severity were observed in 2.6% and 1.7% of patients, respectively. Conclusions: The feasibility of the protocol used in the previous phase II study was reconfirmed in this series, and excellent treatment results were achieved.

Stereotactic Radiotherapy has the potential to produce high local control rates with low risk of severe lung toxicity. From December 2000 to January 2006, 68 inoperable patients (median age 76 years) with stage I NSCLC received definitive hSRT. A mean total dose of 37.5 Gy (24-40 Gy; 60%-isodose) in 3-5 fractions was applied. Immobilisation was carried out by means of a vacuum couch and low pressure foil (Medical Intelligence, Schwab Muenchen, Germany). Staging procedures were thoracic and abdominal CT-scan, FDG-PET and CT or MRI of the brain in all patients. Clinical target volume was the tumor as seen in lung windowing of CT and in FDG-PET. Organ movements (6-22 mm) and patient positioning in the couch (3-12 mm) were added as safety margin for the definition of the planning target volume (PTV), that was enclosed by the 60%-isodose. We observed four (6%) local tumor recurrences, resulting in an actuarial local tumor control rate of 96%, 88% and 88% after 1, 2 and 3 year follow-up. Nineteen patients died, with eight patients due to cancer (12%), two to local tumor progression alone. Cancer-specific survival is 96%, 82% and 73% at 1, 2 and 3 years. Eleven patients died from comorbidities, making a 53% overall 3-year survival. Fifty five percent of the patients were affected by mild acute and subacute side effects, with only 3% experiencing pneumonitis III. Late effects were pneumonitis III in 1%, rib fractures in 3%, and benign pleural effusion in 2 patients. Hypofractionated SRT is safe even in elderly patients with stage I NSCLC and significantly reduced lung capacity. It leads to high local control rates and should be offered to patients not amenable for curative resection.

Surgery with staging using FIGO (1988) classification is accepted management for stage III endometrial carcinoma. The delivery of adjuvant therapy is controversial and tends to be individualised. Retrospective review of stage III endometrial carcinoma patients who underwent radical surgery at the Royal Adelaide and Queen Elizabeth Hospitals from 1984 to 2003 was carried out. Medical records were reviewed for details of patient characteristics, surgery, histopathology, adjuvant therapy and recurrence/survival. Sixty-six patients with a median age of 69 (37-97), had a median follow-up of 26 months (1-188 ). For all stage III patients, the actuarial 5-year disease-free and overall survivals were 50 and 43% respectively. Thirty-five patients received pelvic +/- paraaortic radiotherapy, 5 whole abdominal radiotherapy, 14 vaginal brachytherapy boost, 10 chemotherapy and 13 adjuvant hormones. Forty-six percent of patients recurred in a median time of 13 months (0-95). For these patients, the sites of first recurrence were pelvis in 27%, pelvis and abdomen in 23%, abdomen alone in 13%, distant alone in 27%, distant and abdominal in 7% and all three sites in 3%. On univariate analysis disease-free survival was impacted by; age, grade, parametrial involvement, number of extrauterine sites, lymphovascular invasion, adjuvant radiotherapy to the pelvis alone and postoperative macroscopic residual disease. Lymphovascular invasion, post-operative residual disease and adjuvant pelvic radiotherapy remained significant on multivariate analysis. These outcomes for stage III endometrial carcinoma are comparable to the current literature. Ongoing research is required to establish the most appropriate adjuvant therapy in these high risk patients

Full Text Available Non-small-cell lung cancer (NSCLC remains a leading cause of cancer mortality. The majority of patients present with advanced (stage III-IV disease. Such patients are treated with a variety of therapies including surgery, radiation, and chemotherapy. Despite decades of work, however, overall survival in this group has been resistant to any substantial improvement. This review briefly details the evolution to the current standard of care for advanced NSCLC, advances in systemic therapy, and novel techniques (stereotactic body radiation therapy [SBRT], and transcervical extended mediastinal lymphadenectomy [TEMLA] or video-assisted mediastinal lymphadenectomy [VAMLA] that have been used in localized NSCLC. The utility of these techniques in advanced stage therapy and potential methods of combining these novel techniques with systemic therapy to improve survival are discussed.

Full Text Available Abstract Background Currently, no satisfactory biomarkers are available to screen for lung cancer. Surface-Enhanced Laser Desorption/ionization Time-of- Flight Mass Spectrometry ProteinChip system (SELDI-TOF-MS is one of the currently used techniques to identify biomarkers for cancers. The aim of this study is to explore the application of serum SELDI proteomic patterns to distinguish lung cancer patients from healthy individuals. Methods A total of 208 serum samples, including 158 lung cancer patients and 50 healthy individuals, were randomly divided into a training set (including 11 sera from patients with stages I/II lung cancer, 63 from patients with stages III/IV lung cancer and 20 from healthy controls and a blinded test set (including 43 sera from patients with stages I/II lung cancer, 41 from patients with stages III/IV lung cancer and 30 from healthy controls. All samples were analyzed by SELDI technology. The spectra were generated on weak cation exchange (WCX2 chips, and protein peaks clustering and classification analyses were made using Ciphergen Biomarker Wizard and Biomarker Pattern software, respectively. We additionally determined Cyfra21-1 and NSE in the 208 serum samples included in this study using an electrochemiluminescent immunoassay. Results Five protein peaks at 11493, 6429, 8245, 5335 and 2538 Da were automatically chosen as a biomarker pattern in the training set. When the SELDI marker pattern was tested with the blinded test set, it yielded a sensitivity of 86.9%, a specificity of 80.0% and a positive predictive value of 92.4%. The sensitivities provided by Cyfra21-1 and NSE used individually or in combination were significantly lower than that of the SELDI marker pattern (P P Conclusion These results suggest that serum SELDI protein profiling can distinguish lung cancer patients, especially NSCLC patients, from normal subjects with relatively high sensitivity and specificity, and the SELDI-TOF-MS is a potential tool

Full Text Available In Taiwan, cancer is the top cause of death, and the mortality rate of lung cancer is the highest of all cancers. Some studies have demonstrated that multidisciplinary team (MDT care can improve survival rates of non-small cell lung cancer (NSCLC patients. However, no study has discussed the effect of MDT care on different stages of NSCLC. The target population for this study consisted of patients with NSCLC newly diagnosed in the 2005-2010 Cancer Registry. The data was linked with the 2002-2011 National Health Insurance Research Database and the 2005-2011 Cause of Death Statistics Database. The multivariate Cox proportional hazards model was used to explore whether the involvement of MDT care had an effect on survival. This study applied the propensity score as a control variable to reduce selection bias between patients with and without involvement of MDT care. The adjusted hazard ratio (HR of death of MDT participants with stage III & IV NSCLC was significantly lower than that of MDT non-participants (adjusted HR = 0.87, 95% confidence interval = 0.84-0.90. This study revealed that MDT care are significantly associated with higher survival rate of patients with stage III and IV NSCLC, and thus MDT care should be used in the treatment of these patients.

Current Treatments for Surgically Resectable, Limited-Stage, and Extensive-Stage Small Cell Lung Cancer.

The prevalence of small cell lung cancer (SCLC) has declined in the U.S. as the prevalence of tobacco use has declined. However, a significant number of people in the U.S. are current or former smokers and are at risk of developing SCLC. Routine histological or cytological evaluation can reliably make the diagnosis of SCLC, and immunohistochemistry stains (thyroid transcription factor-1, chromogranin, synaptophysin, and CD56) can be used if there is uncertainty about the diagnosis. Rarely do patients present with SCLC amendable to surgical resection, and evaluation requires a meticulous workup for extra-thoracic metastases and invasive staging of the mediastinum. Resected patients require adjuvant chemotherapy and/or thoracic radiation therapy (TRT), and prophylactic cranial radiation (PCI) should be considered depending on the stage. For limited-stage disease, concurrent platinum-etoposide and TRT followed by PCI is the standard. Thoracic radiation therapy should be started early in treatment, and can be given twice daily to 45 Gy or once daily to 60-70 Gy. For extensive-stage disease, platinum-etoposide remains the standard first-line therapy, and the standard second-line therapy is topotecan. Preliminary studies have demonstrated the activity of immunotherapy, and the response rate is approximately 10-30% with some durable responses observed. Rovalpituzumab tesirine, an antibody drug conjugate, has shown promising activity in patients with high delta-like protein 3 tumor expression (approximately 70% of patients with SCLC). The emergence of these and other promising agents has rekindled interest in drug development in SCLC. Several ongoing trials are investigating novel agents in the first-line, maintenance, and second-line settings. This review will provide an update on the standard therapies for surgically resected limited-stage small cell lung cancer and extensive-stage small cell lung cancer that have been investigated in recent clinical trials. © Alpha

Over the past two decades, the International Association for the Study of Lung Cancer (IASLC) Staging Project has been a steady source of evidence-based recommendations for the TNM classification for lung cancer published by the Union for International Cancer Control and the American Joint Committee on Cancer. The Staging and Prognostic Factors Committee of the IASLC is now issuing a call for participation in the next phase of the project, which is designed to inform the ninth edition of the TNM classification for lung cancer. Following the case recruitment model for the eighth edition database, volunteer site participants are asked to submit data on patients whose lung cancer was diagnosed between January 1, 2011, and December 31, 2019, to the project by means of a secure, electronic data capture system provided by Cancer Research And Biostatistics in Seattle, Washington. Alternatively, participants may transfer existing data sets. The continued success of the IASLC Staging Project in achieving its objectives will depend on the extent of international participation, the degree to which cases are entered directly into the electronic data capture system, and how closely externally submitted cases conform to the data elements for the project.

SU-E-J-87: Ventilation Weighting Effect On Mean Doses of Both Side Lungs for Patients with Advanced Stage Lung Cancer

International Nuclear Information System (INIS)

Qu, H; Xia, P; Yu, N

2015-01-01

Purpose: To study ventilation weighting effect on radiation doses to both side lungs for patients with advanced stage lung cancer. Methods: Fourteen patients with advanced stage lung cancer were included in this retrospective study. Proprietary software was developed to calculate the lung ventilation map based on 4DCT images acquired for radiation therapy. Two phases of inhale (0%) and exhale (50%) were used for the lung ventilation calculations. For each patient, the CT images were resampled to the same dose calculation resolution of 3mmx3mmx3mm. The ventilation distribution was then normalized by the mean value of the ventilation. The ventilation weighted dose was calculated by applying linearly weighted ventilation to the dose of each pixel. The lung contours were automatically delineated from patient CT image with lung window, excluding the tumor and high density tissues. For contralateral and ipsilateral lungs, the mean lung doses from the original plan and ventilation weighted mean lung doses were compared using two tail t-Test. Results: The average of mean dose was 6.1 ±3.8Gy for the contralateral lungs, and 26.2 ± 14.0Gy for the ipsilateral lungs. The average of ventilation weighted dose was 6.3± 3.8Gy for the contralateral lungs and 24.6 ± 13.1Gy for the ipsilateral lungs. The statistics analysis shows the significance of the mean dose increase (p<0.015) for the contralateral lungs and decrease (p<0.005) for the ipsilateral lungs. Conclusion: Ventilation weighted doses were greater than the un-weighted doses for contralateral lungs and smaller for ipsilateral lungs. This Result may be helpful to understand the radiation dosimetric effect on the lung function and provide planning guidance for patients with advance stage lung cancer

Idiopathic pulmonary fibrosis is a progressive lung disease with variable course. The Gender-Age-Physiology (GAP) Index and staging system uses clinical variables to stage mortality risk. It is unknown whether clinical staging predicts future decline in pulmonary function. We assessed whether the GAP stage predicts future pulmonary function decline and whether interval pulmonary function change predicts mortality after accounting for stage. Patients with idiopathic pulmonary fibrosis (N = 657) were identified retrospectively at three tertiary referral centers, and baseline GAP stages were assessed. Mixed models were used to describe average trajectories of FVC and diffusing capacity of the lung for carbon monoxide (Dlco). Multivariable Cox proportional hazards models were used to assess whether declines in pulmonary function ≥ 10% in 6 months predict mortality after accounting for GAP stage. Over a 2-year period, GAP stage was not associated with differences in yearly lung function decline. After accounting for stage, a 10% decrease in FVC or Dlco over 6 months independently predicted death or transplantation (FVC hazard ratio, 1.37; Dlco hazard ratio, 1.30; both, P ≤ .03). Patients with GAP stage 2 with declining pulmonary function experienced a survival profile similar to patients with GAP stage 3, with 1-year event-free survival of 59.3% (95% CI, 49.4-67.8) vs 56.9% (95% CI, 42.2-69.1). Baseline GAP stage predicted death or lung transplantation but not the rate of future pulmonary function decline. After accounting for GAP stage, a decline of ≥ 10% over 6 months independently predicted death or lung transplantation. Copyright © 2016 American College of Chest Physicians.

Full Text Available Abstract Background In recent decades, melanoma incidence has been increasing in European countries; in 2006, there were approximately 60,000 cases leading to 13,000 deaths. Within Europe there is some geographical variation in the incidence of melanoma, with the highest rates reported in Scandinavia (15 cases per 100,000 inhabitants per year and the lowest in the Mediterranean countries (5 to 7 cases per 100,000 inhabitants per year. Methods The present article is based on the information collected in the MELODY study (MELanoma treatment patterns and Outcomes among patients with unresectable stage III or stage IV Disease: a retrospective longitudinal survey. In that study, the medical charts of patients were reviewed to document current treatment patterns and to analyse information on patients, disease characteristics and healthcare resource utilization related to the treatment of advanced melanoma regarding patients who presented with a diagnosis of malignant melanoma (stage I to IV at participating sites between 01 July, 2005 and 30 June, 2006. Results Summarizing, though the length of the follow-up period varies among sample patients, an amount of the yearly cost per patient can be estimated, dividing the average per patient total cost (€ 5.040 by the average follow-up duration (17.5 months and reporting to one year; on these grounds, unresectable stage III or stage IV melanoma in Italy would cost € 3,456 per patient per year.

Because of the considerable heterogeneity in breast carcinoma with noninflammatory skin involvement (T4b/Stage IIIB), a revision was proposed of the TNM staging system that would classify these tumors exclusively based on their tumor size and lymph node status. In the current study, the authors evaluated how implementation of this proposal will affect Stage III noninflammatory breast cancer. Two hundred seven patients who were classified with noninflammatory Stage III breast cancer were treated consecutively between 1990 and 1999 at the University Hospital Basel, Switzerland. To assess the extent of T4b/Stage IIIB tumors independent of the clinicopathologic feature of skin involvement, the reclassification was undertaken. Of 68 patients who had nonmetastatic T4b breast cancer, 37 patients (54.4%) had a tumor extent in accordance with Stage I/II and had improved disease-specific survival (DSS) compared with patients who had Stage III breast cancer (P = .008). Excluding those patients from Stage III led to a 17.9% reduction of the number of patients in this group (n = 170 patients). The 10-year DSS declined from 48.5% to 42.9%. Considerable numbers of patients who are classified with noninflammatory Stage IIIB breast cancer show only a limited disease extent. Through a revision of the T4 category, these low-risk patients were excluded from the highest nonmetastatic TNM stage, and overstaging could be avoided. This procedure decreased the degree of heterogeneity of the entire Stage III group and may result in a more precise assessment of this disease entity. Copyright 2006 American Cancer Society.

Several clinical guidelines indicate that brain metastasis screening (BMS) should be guided by disease stage in non-small cell lung cancer (NSCLC). We estimate that screening is performed more broadly in practice, and patients undergo brain imaging at considerable cost with questionable benefit. Our aim was to quantify the use and detection rate of BMS in a contemporary cohort staged with 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (PET-CT). We conducted a retrospective review of prospectively collected data from three major lung cancer referral centres in Brisbane between January 2011 and December 2015. Patients included had a new diagnosis of NSCLC and had undergone a PET-CT to stage extra-cranial disease. BMS was defined as dedicated brain imaging with contrast-enhanced computed tomography (CE-CT) or magnetic resonance (MR), in the absence of clinically apparent neurological deficits. A total of 1751 eligible cases were identified and of these 718 (41%) underwent BMS. The majority had CE-CT imaging (n = 703). Asymptomatic brain metastases (BM) were detected in 18 patients (2.5%). Of these patients, 12 had concurrent non-brain metastases. Only six patients (0.8%) had BM alone. The rate of detection increased with N-stage (P = 0.02) and overall stage (P < 0.001). It was 0.5%, 1%, 1.6% and 7.3% for stage I, II, III and IV respectively. The overall screening rate increased with T-stage (P = 0.001), N-Stage (P < 0.001) and overall stage (P < 0.001). Non-small cell lung cancer BMS practices remain at odds with published guidelines. The low number of occult BMs detected supports the existing international recommendations. Rationalising BMS would minimise the burden on patients and the health care system. © 2018 The Royal Australian and New Zealand College of Radiologists.

However, the significance of these factors as predictors of overall survival (OS and postoperative recurrence survival (PRS has not been sufficiently elucidated. The objective here was to investigate EGFR mutation status and p-stage, which affect PRS and OS in patients with completely resected lung adenocarcinoma, using a different database.Patients and methods: We retrospectively reviewed 56 consecutive lung adenocarcinoma patients with disease recurrence in St. Marianna University Hospital between January 2010 and December 2014.Results: EGFR mutants (M were detected in 16/56 patients (29%. The patients with EGFR M had a better OS than those with EGFR wild-type (WT status (5-year survival: 50.3% vs 43.1, P=0.133. There was no significant difference in the 3-year recurrence-free survival rate between patients with M and WT (6.3% vs 7.7%, P=0.656, and the patients with EGFR M had a significantly better 3-year PRS than those with WT (77.4% vs 51.7%, P=0.033.

1979-01-01

Cytotoxicity of peripheral blood lymphocytes against allogeneic target cells of bronchogenic carcinoma was examined by a microcytotoxicity test before, during, and after radiotherapy in primary lung cancer patients. Before the treatment, cytotoxicity was depressed only slightly in patients in stage III and strikingly in those in stage IV, as compared to the values in patients at earlier stages of lung cancer such as stages I and II. Local irradiation scarcely affected cytotoxicity at stages II and III, but augmented remarkably at stage IV. The number of peripheral blood lymphocytes decreased profoundly during and after radiotherapy in all cases of stages II, III, and IV. Although radiotherapy exhibited various effects on the cytotoxic activity of lymphocytes and the number of peripheral blood lymphocytes, only the cytotoxic activity at the end of radiotherapy correlated well with the reduction in tumor size.

Purpose: Prognostic factors can guide the physician in selecting the optimal treatment for an individual patient. This study investigates the prognostic value of erythropoietin (EPO) and EPO receptor (EPO-R) expression of tumor cells for locoregional control and survival in non-small-cell lung cancer (NSCLC) patients. Methods and Materials: Fourteen factors were investigated in 62 patients irradiated for stage II/III NSCLC, as follows: age, gender, Karnofsky performance score (KPS), histology, grading, TNM/American Joint Committee on Cancer (AJCC) stage, surgery, chemotherapy, pack years (average number of packages of cigarettes smoked per day multiplied by the number of years smoked), smoking during radiotherapy, hemoglobin levels during radiotherapy, EPO expression, and EPO-R expression. Additionally, patients with tumors expressing both EPO and EPO-R were compared to those expressing either EPO or EPO-R and to those expressing neither EPO nor EPO-R. Results: On univariate analysis, improved locoregional control was associated with AJCC stage II cancer (p 70 (p = 0.08), an N stage of 0 to 1 (p = 0.07), and no EPO-R expression (p = 0.10). On multivariate analysis, AJCC stage II and no EPO expression remained significant. No smoking during radiotherapy was almost significant. On univariate analysis, improved survival was associated with N stage 0 to 1 (p = 0.009), surgery (p = 0.039), hemoglobin levels of ≥12 g/d (p = 0.016), and no EPO expression (p = 0.001). On multivariate analysis, N stage 0 to 1 and no EPO expression maintained significance. Hemoglobin levels of ≥12 g/d were almost significant. On subgroup analyses, patients with tumors expressing both EPO and EPO-R had worse outcomes than those expressing either EPO or EPO-R and those expressing neither EPO nor RPO-R. Conclusions: EPO expression of tumor cells was an independent prognostic factor for locoregional control and survival in patients irradiated for NSCLC. EPO-R expression showed a trend

Purpose: Improved local tumor control (LC) improves survival of patients with non-small cell lung cancer (NSCLC). We estimated the capability of surgical and non-surgical options to improve LC further in this disease. Methods: Eligible studies were phase III trials reporting 2-year survival data as well as the incidence of LC and/or distant metastases. Effect estimates, as well as the statistical uncertainty of these, were combined in order to estimate the benefit in terms of LC from combining multiple modalities. Results: It was estimated that the highest rates of LC can be obtained with high-dose concurrent chemo-radiation followed by surgery. In this situation, escalating the pre-operative radiation dose from 45 to 66 Gy, delivered concurrently with chemotherapy, could increase LC from 58% to 76%. Toxicity may also be higher, but could not be estimated. Without surgery, the gain in LC from concurrent chemo-radiation versus sequential, corresponds to a radiation dose increase from 65 to 72 Gy. Conclusions: We hypothesize that high-dose concurrent chemo-radiation followed by surgery could be superior to other current treatment approaches for selected patients with stage III NSCLC, provided toxicity would be low. At present, high-dose concurrent chemo-radiation followed by surgery should be considered experimental.

The results of postoperative radiation therapy in 12 patients with Stage III thymoma treated during the period 1966-1986 were reviewed. Surgical therapy consisted of total resection in one, subtotal resection in seven, and biopsy only in four. Megavoltage irradiation in the dose range of 3,000-5,600 cGy was employed, with the majority receiving a dose of at least 5,000 cGy. The local control rate was 67%. The actuarial 5-year observed and adjusted survival rates were 57% and 75%, respectively. These results indicate that postoperative radiation therapy is an effective therapeutic modality in the control of Stage III thymoma

The main aim of the current study was to assess the dosimetric accuracy and clinical quality of volumetric modulated arc therapy (VMAT) plans for stereotactic (stage I) and conventional (stage III) lung cancer treatments planned with Eclipse version 10.0 Anisotropic Analytical Algorithm (AAA) and Acuros XB (AXB) algorithm. The dosimetric impact of using AAA instead of AXB, and grid size 2.5 mm instead of 1.0 mm for VMAT treatment plans was evaluated. The clinical plan quality of AXB VMAT was assessed using 45 stage I and 73 stage III patients, and was compared with published results, planned with VMAT and hybrid-VMAT techniques. The dosimetric impact on near-minimum PTV dose (D 98% ) using AAA instead of AXB was large (underdose up to 12.3%) for stage I and very small (underdose up to 0.8%) for stage III lung treatments. There were no significant differences for dose volume histogram (DVH) values between grid sizes. The calculation time was significantly higher for AXB grid size 1.0 than 2.5 mm (p < 0.01). The clinical quality of the VMAT plans was at least comparable with clinical qualities given in literature of lung treatment plans with VMAT and hybrid-VMAT techniques. The average mean lung dose (MLD), lung V 20Gy and V 5Gy in this study were respectively 3.6 Gy, 4.1% and 15.7% for 45 stage I patients and 12.4 Gy, 19.3% and 46.6% for 73 stage III lung patients. The average contra-lateral lung dose V 5Gy-cont was 35.6% for stage III patients. For stereotactic and conventional lung treatments, VMAT calculated with AXB grid size 2.5 mm resulted in accurate dose calculations. No hybrid technique was needed to obtain the dose constraints. AXB is recommended instead of AAA for avoiding serious overestimation of the minimum target doses compared to the actual delivered dose

The updated eighth edition of the tumor, node, metastasis (TNM) classification for lung cancer includes revisions to T and M descriptors. In terms of the M descriptor, the classification of intrathoracic metastatic disease as M1a is unchanged from TNM-7. Extrathoracic metastatic disease, which was classified as M1b in TNM-7, is now subdivided into M1b (single metastasis, single organ) and M1c (multiple metastases in one or multiple organs) descriptors. In this article, the rationale for changes in the M descriptors, the utility of preoperative staging with PET/computed tomography, and the treatment options available for patients with oligometastatic disease are discussed.

The staging procedures for small cell lung cancer do not differ appreciably from those for other forms of lung cancer. For practical purposes, the TNM stages are usually collapsed into a simple binary classification: limited disease and extensive disease. This study was performed to answer the question of whether fluorine-18 labelled 2-deoxy-2-D-glucose positron emission tomography (FDG-PET) imaging permits appropriate work-up (including both primary and follow-up staging) of patients presenting with small cell lung cancer, as compared with currently recommended staging procedures. Thirty-six FDG-PET examinations were performed in 30 patients with histologically proven small cell lung cancer. Twenty-four patients were examined for primary staging while four were imaged for therapy follow-up only. Two patients underwent both primary staging and up to four examinations for therapy follow-up. Static PET imaging was performed according to a standard protocol. Image reconstruction was based on an ordered subset expectation maximization algorithm including post-injection segmented attenuation correction. Results of FDG-PET were compared with those of the sum of other staging procedures. Identical results from FDG-PET and the sum of the other staging procedures were obtained in 23 of 36 examinations (6 x limited disease, 12 x extensive disease, 5 x no evidence of disease). In contrast to the results of conventional staging, FDG-PET indicated extensive disease resulting in an up-staging in seven patients. In one patient in whom there was no evidence for tumour on conventional investigations following treatment, FDG-PET was suggestive of residual viability of the primary tumour. Furthermore, discordant results were observed in five patients with respect to lung, bone, liver and adrenal gland findings, although in these cases the results did not affect staging as limited or extensive disease. Moreover, FDG-PET appeared to be more sensitive for the detection of metastatic

Purpose: We retrospectively compared the survival rate in patients with non-small-cell lung cancer (NSCLC) treated with radiofrequency ablation (RFA), surgery, or chemotherapy according to lung cancer staging. Materials and Methods: From 2000 to 2004, 77 NSCLC patients, all of whom had WHO performance status 0–2 and were >60 years old, were enrolled in a cancer registry and retrospectively evaluated. RFA was performed on patients who had medical contraindications to surgery/unsuitability for surgery, such as advanced lung cancer or refusal of surgery. In the RFA group, 40 patients with inoperable NSCLC underwent RFA under computed tomography (CT) guidance. These included 16 patients with stage I to II cancer and 24 patients with stage III to IV cancer who underwent RFA in an adjuvant setting. In the comparison group (n = 37), 13 patients with stage I to II cancer underwent surgery; 18 patients with stage III to IV cancer underwent chemotherapy; and 6 patients with stage III to IV cancer were not actively treated. The survival curves for RFA, surgery, and chemotherapy in these patients were calculated using Kaplan–Meier method. Results: Median survival times for patients treated with (1) surgery alone and (2) RFA alone for stage I to II lung cancer were 33.8 and 28.2 months, respectively (P = 0.426). Median survival times for patients treated with (1) chemotherapy alone and (2) RFA with chemotherapy for stage III to IV cancer were 29 and 42 months, respectively (P = 0.03). Conclusion: RFA can be used as an alternative treatment to surgery for older NSCLC patients with stage I to II inoperable cancer and can play a role as adjuvant therapy with chemotherapy for patients with stage III to IV lung cancer.

Objective We previously reported that the staging system and epidermal growth factor receptor (EGFR) mutation status are key factors for treatment strategy and predicting survival. However, the significance of these factors as predictors of overall survival (OS) and postoperative recurrence survival (PRS) has not been sufficiently elucidated. The objective here was to investigate EGFR mutation status and p-stage, which affect PRS and OS in patients with completely resected lung adenocarcinoma, using a different database. Patients and methods We retrospectively reviewed 56 consecutive lung adenocarcinoma patients with disease recurrence in St. Marianna University Hospital between January 2010 and December 2014. Results EGFR mutants (M) were detected in 16/56 patients (29%). The patients with EGFR M had a better OS than those with EGFR wild-type (WT) status (5-year survival: 50.3% vs 43.1, P=0.133). There was no significant difference in the 3-year recurrence-free survival rate between patients with M and WT (6.3% vs 7.7%, P=0.656), and the patients with EGFR M had a significantly better 3-year PRS than those with WT (77.4% vs 51.7%, P=0.033). The 3-year PRS rate for patients with M/pathologic stage (p-stage) I–II (87.5%) was better than that for patients with M/p-stage III (60.0%), WT/p-stage I–II (52.7%), and WT/p-stage III (43.8%). There was a significant difference between patients with M/p-stage I and WT/p-stage I–II or WT/p-stage III (P=0.021 and 0.030, respectively). During the study period, of the 16 patients with mutants, 12 patients (75%) received EGFR-tyrosine kinase inhibitor (TKI) therapy and among the 40 patients with WT, no patient received EGFR-TKI therapy. Multivariate survival analysis showed that patients with EGFR-TKI therapy had a statistically significant association with favorable PRS (hazard ratio 0.271; 95% confidence interval 0.074–1.000; P=0.050). Conclusion EGFR status and p-stage were found to be essential prognostic factors for

While surgery is considered standard of care for early stage (I/II), non-small-cell lung cancer (NSCLC), radiotherapy is a widely accepted alternative for medically unfit patients or those who refuse surgery. International guidelines recommend several treatment options, comprising stereotactic body radiation therapy (SBRT) for small tumors, conventional radiotherapy ≥ 60 Gy for larger sized especially centrally located lesions or continuous hyperfractionated accelerated RT (CHART). This study presents clinical outcome and toxicity for patients treated with a dose-differentiated accelerated schedule using 1.8 Gy bid (DART-bid). Between April 2002 and December 2010, 54 patients (median age 71 years, median Karnofsky performance score 70 %) were treated for early stage NSCLC. Total doses were applied according to tumor diameter: 73.8 Gy for 6 cm. The median follow-up was 28.5 months (range 2-108 months); actuarial local control (LC) at 2 and 3 years was 88 %, while regional control was 100 %. There were 10 patients (19 %) who died of the tumor, and 18 patients (33 %) died due to cardiovascular or pulmonary causes. A total of 11 patients (20 %) died intercurrently without evidence of progression or treatment-related toxicity at the last follow-up, while 15 patients (28 %) are alive. Acute esophagitis ≤ grade 2 occurred in 7 cases, 2 patients developed grade 2 chronic pulmonary fibrosis. DART-bid yields high LC without significant toxicity. For centrally located and/or large (> 5 cm) early stage tumors, where SBRT is not feasible, this method might serve as radiotherapeutic alternative to present treatment recommendations, with the need of confirmation in larger cohorts.

Objective: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive, safe and accurate method for collecting samples from mediastinal and hilar lymph nodes. This study focused on the initial results obtained with EBUS-TBNA for lung cancer and lymph node staging at three teaching hospitals in Brazil. Methods: This was a retrospective analysis of patients diagnosed with lung cancer and submitted to EBUS-TBNA for mediastinal lymph node staging. The EBUS-TBNA procedures, which involved the use of an EBUS scope, an ultrasound processor, and a compatible, disposable 22 G needle, were performed while the patients were under general anesthesia. Results: Between January of 2011 and January of 2014, 149 patients underwent EBUS-TBNA for lymph node staging. The mean age was 66 ± 12 years, and 58% were male. A total of 407 lymph nodes were sampled by EBUS-TBNA. The most common types of lung neoplasm were adenocarcinoma (in 67%) and squamous cell carcinoma (in 24%). For lung cancer staging, EBUS-TBNA was found to have a sensitivity of 96%, a specificity of 100%, and a negative predictive value of 85%. Conclusions: We found EBUS-TBNA to be a safe and accurate method for lymph node staging in lung cancer patients. PMID:25750671

This study aims to develop a computer-aided diagnosis (CADx) scheme for classification between malignant and benign lung nodules, and also assess whether CADx performance changes in detecting nodules associated with early and advanced stage lung cancer. The study involves 243 biopsy-confirmed pulmonary nodules. Among them, 76 are benign, 81 are stage I and 86 are stage III malignant nodules. The cases are separated into three data sets involving: (1) all nodules, (2) benign and stage I malignant nodules, and (3) benign and stage III malignant nodules. A CADx scheme is applied to segment lung nodules depicted on computed tomography images and we initially computed 66 3D image features. Then, three machine learning models namely, a support vector machine, naïve Bayes classifier and linear discriminant analysis, are separately trained and tested by using three data sets and a leave-one-case-out cross-validation method embedded with a Relief-F feature selection algorithm. When separately using three data sets to train and test three classifiers, the average areas under receiver operating characteristic curves (AUC) are 0.94, 0.90 and 0.99, respectively. When using the classifiers trained using data sets with all nodules, average AUC values are 0.88 and 0.99 for detecting early and advanced stage nodules, respectively. AUC values computed from three classifiers trained using the same data set are consistent without statistically significant difference (p  >  0.05). This study demonstrates (1) the feasibility of applying a CADx scheme to accurately distinguish between benign and malignant lung nodules, and (2) a positive trend between CADx performance and cancer progression stage. Thus, in order to increase CADx performance in detecting subtle and early cancer, training data sets should include more diverse early stage cancer cases.

Purpose: To determine the frequency and clinical significance of epidermal growth factor receptor (EGFR) mutations in patients with potentially curable stage III non–small-cell lung cancer (NSCLC) who are eligible for definitive chemoradiotherapy (CRT). Patients and Methods: Between January 2001 and December 2010, we analyzed the EGFR mutational status in consecutive NSCLC patients who were treated by CRT. The response rate, relapse-free survival, 2-year relapse-free rate, initial relapse sites, and overall survival of the patients were investigated. Results: A total of 528 patients received CRT at our hospital during the study period. Of these, 274 were diagnosed as having nonsquamous NSCLC. Sufficient specimens for mutational analyses could be obtained from 198 of these patients. The proportion of patients with EGFR activating mutations was 17%. In addition to the well-known characteristics of patients carrying EGFR mutations (female, adenocarcinoma, and never/light smoker), the proportion of cases with smaller primary lesions (T1/2) was found to be higher in patients with EGFR mutations than in those with wild-type EGFR. Patients with EGFR mutations showed similar response rate, relapse-free survival, and 2-year relapse-free rates as compared to patients with wild-type EGFR. Local relapses as the site of initial relapse occurred significantly less frequently in patients with EGFR mutation (4% vs 21%; P=.045). Patients with EGFR mutations showed longer local control (adjusted hazard ratio 0.49; P=.043). After disease progression, a majority of the patients with EGFR mutations received EGFR tyrosine kinase inhibitors (62%), and these patients showed longer postprogression survival than those with wild-type EGFR. Conclusions: Our study is the first to show radiosensitive biology of EGFR-mutated tumors in definitive CRT with curative intent. This finding could serve as a credible baseline estimate of EGFR-mutated population in stage III nonsquamous NSCLC

Purpose: To present treatment outcomes of hypofractionated high-dose proton beam therapy for Stage I non-small-cell lung cancer (NSCLC). Methods and Materials: Twenty-one patients with Stage I NSCLC (11 with Stage IA and 10 with Stage IB) underwent hypofractionated high-dose proton beam therapy. At the time of irradiation, patient age ranged from 51 to 85 years (median, 74 years). Nine patients were medically inoperable because of comorbidities, and 12 patients refused surgical resection. Histology was squamous cell carcinoma in 6 patients, adenocarcinoma in 14, and large cell carcinoma in 1. Tumor size ranged from 10 to 42 mm (median, 25 mm) in maximum diameter. Three and 18 patients received proton beam irradiation with total doses of 50 Gy and 60 Gy in 10 fractions, respectively, to primary tumor sites. Results: Of 21 patients, 2 died of cancer and 2 died of pneumonia at a median follow-up period of 25 months. The 2-year overall and cause-specific survival rates were 74% and 86%, respectively. All but one of the irradiated tumors were controlled during the follow-up period. Five patients showed recurrences 6-29 months after treatment, including local progression and new lung lesions outside of the irradiated volume in 1 and 4 patients, respectively. The local progression-free and disease-free rates were 95% and 79% at 2 years, respectively. No therapy-related toxicity of Grade ≥3 was observed. Conclusions: Hypofractionated high-dose proton beam therapy seems feasible and effective for Stage I NSCLC. Proton beams may contribute to enhanced efficacy and lower toxicity in the treatment of patients with Stage I NSCLC

Full Text Available ABSTRACT: Intermittent hemodialysis (IHD is a form of renal replacement that is used in veterinary medicine for cases involving drug removal, electrolyte imbalance, acute kidney injury, and chronic kidney disease (CKD. The aim of the present study was to verify the efficacy of IHD in dogs with CKD staged at grade III and to evaluate the effect of IHD on quality of life. Twelve dogs with CKD at stage III met the inclusion criteria and were divided equally into two groups. The control group (n=6 received only clinical treatment and intravenous fluid therapy, and the hemodialysis group (n=6 received clinical and IHD treatments. Blood samples were collected before and after treatments in both groups. We evaluated complications and clinical parameters of IHD every 30 minutes. Hemodialysis decreased serum urea, creatinine, and phosphorus. Despite the evident removal of nitrogen compounds, dialysis treatment did not increase survival time in these patients. The results of this study do not support the early use of dialysis in dogs with chronic kidney disease stage III.

Purpose Concurrent chemoradiotherapy is standard treatment for patients with stage III non-small-cell lung cancer. Elderly patients may experience increased rates of adverse events (AEs) or less benefit from concurrent chemoradiotherapy. Patients and Methods Individual patient data were collected from 16 phase II or III trials conducted by US National Cancer Institute-supported cooperative groups of concurrent chemoradiotherapy alone or with consolidation or induction chemotherapy for stage III non-small-cell lung cancer from 1990 to 2012. Overall survival (OS), progression-free survival, and AEs were compared between patients age ≥ 70 (elderly) and those younger than 70 years (younger). Unadjusted and adjusted hazard ratios (HRs) for survival time and CIs were estimated by single-predictor and multivariable frailty Cox models. Unadjusted and adjusted odds ratio (ORs) for AEs and CIs were obtained from single-predictor and multivariable generalized linear mixed-effect models. Results A total of 2,768 patients were classified as younger and 832 as elderly. In unadjusted and multivariable models, elderly patients had worse OS (HR, 1.20; 95% CI, 1.09 to 1.31 and HR, 1.17; 95% CI, 1.07 to 1.29, respectively). In unadjusted and multivariable models, elderly and younger patients had similar progression-free survival (HR, 1.01; 95% CI, 0.93 to 1.10 and HR, 1.00; 95% CI, 0.91 to 1.09, respectively). Elderly patients had a higher rate of grade ≥ 3 AEs in unadjusted and multivariable models (OR, 1.35; 95% CI, 1.07 to 1.70 and OR, 1.38; 95% CI, 1.10 to 1.74, respectively). Grade 5 AEs were significantly higher in elderly compared with younger patients (9% v 4%; P < .01). Fewer elderly compared with younger patients completed treatment (47% v 57%; P < .01), and more discontinued treatment because of AEs (20% v 13%; P < .01), died during treatment (7.8% v 2.9%; P < .01), and refused further treatment (5.8% v 3.9%; P = .02).

BACKGROUND: Up to 45% of operations with curative intent for non-small-cell lung cancer (NSCLC) can be regarded as futile, apparently because the stage of the disease is more advanced than expected preoperatively. During the past decade several studies have evaluated the usefulness of endoscopic...... ultrasound guided fine needle aspiration biopsy (EUS-FNA) in lung cancer staging with promising results. However, no randomised trials have been performed, in which a staging strategy with EUS-FNA performed in all patients is compared with a conventional workup. METHODS: Before surgery (i.e. mediastinoscopy...

Purpose: To assess quantitatively the impact of incorporating functional lung imaging into intensity-modulated radiation therapy planning for locally advanced non-small cell lung cancer (NSCLC). Methods and Materials: Sixteen patients with advanced-stage NSCLC who underwent radiotherapy were included in this study. Before radiotherapy, each patient underwent lung perfusion imaging with single-photon-emission computed tomography and X-ray computed tomography (SPECT-CT). The SPECT-CT was registered with simulation CT and was used to segment the 50- and 90-percentile hyperperfusion lung (F50 lung and F90 lung). Two IMRT plans were designed and compared in each patient: an anatomic plan using simulation CT alone and a functional plan using SPECT-CT in addition to the simulation CT. Dosimetric parameters of the two types of plans were compared in terms of tumor coverage and avoidance of normal tissues. Results: In incorporating perfusion information in IMRT planning, the median reductions in the mean doses to the F50 and F90 lung in the functional plan were 2.2 and 4.2 Gy, respectively, compared with those in the anatomic plans. The median reductions in the percentage of volume irradiated with >5 Gy, >10 Gy, and >20 Gy in the functional plans were 7.1%, 6.0%, and 5.1%, respectively, for F50 lung, and 11.7%, 12.0%, and 6.8%, respectively, for F90 lung. A greater degree of sparing of the functional lung was achieved for patients with large perfusion defects compared with those with relatively uniform perfusion distribution. Conclusion: Function-guided IMRT planning appears to be effective in preserving functional lung in locally advanced-stage NSCLC patients

Full Text Available Background and objective Approximately 35%-40% of patients with newly diagnosed non-small cell Lung cancer have locally advanced disease. The average survival time of these patients only have 6-8 months with chemotherapy. The aim of this study is to explore and summarize the probability of detection of micrometastasis in peripheral blood for molecular staging, and for selection of indication of surgical treatment, and beneficiary of neoadjuvant chemotherapy and postoperative adjuvant therapy in locally advanced lung cancer; to summarize the long-time survival result of personalized surgical treatment of 516 patients with locally advanced non-small cell lung cancer based on molecular staging methods. Methods CK19 mRNA expression of peripheral blood samples was detected in 516 lung cancer patients by RT-PCR before operation for molecular diagnosis of micrometastasis, personalized molecular staging, and for selection of indication of surgical treatment and the beneficiary of neoadjuvant chemotherapy and postoperative adjuvant therapy in patients with locally advanced nonsmall cell lung cancer invaded heart, great vessels or both. The long-term survival result of personalized surgical treatment was retrospectively analyzed in 516 patients with locally advanced non-small cell lung cancer based on molecular staging methods. Results There were 322 patients with squamous cell carcinoma and 194 cases with adenocarcinoma in the series of 516 patients with locally advanced lung cancer involved heart, great vessels or both. There were 112 patients with IIIA disease and 404 cases with IIIB disease according to P-TNM staging. There were 97 patients with M-IIIA disease, 278 cases with M-IIIB disease and 141 cases with III disease according to our personalized molecular staging. Of the 516 patients, bronchoplastic procedures and pulmonary artery reconstruction was carried out in 256 cases; lobectomy combined with resection and reconstruction of partial left

The purpose of our study was to test a new staging algorithm, combining clinical TNM staging (cTNM) with whole-body metabolic active tumor volume (MATV-WB), with the goal of improving prognostic ability and stratification power. Initial staging [{sup 18}F]FDG PET/CT of 278 non-small cell lung cancer (NSCLC) patients, performed between January/2011 and April/2016, 74(26.6%) women, 204(73.4%) men; aged 34-88 years (mean ± SD:66 ± 10), was retrospectively evaluated, and MATV-WB was quantified. Each patient's follow-up time was recorded: 0.7-83.6 months (mean ± SD:25.1 ± 20.3). MATV-WB was an independent and statistically-significant predictor of overall survival (p < 0.001). The overall survival predictive ability of MATV-WB (C index: mean ± SD = 0.7071 ± 0.0009) was not worse than cTNM (C index: mean ± SD = 0.7031 ± 0.007) (Z = -0.143, p = 0.773). Estimated mean survival times of 56.3 ± 3.0 (95%CI:50.40-62.23) and 21.7 ± 2.2 months (95%CI:17.34-25.98) (Log-Rank = 77.48, p < 0.001), one-year survival rate of 86.8% and of 52.8%, and five-year survival rate of 53.6% and no survivors, were determined, respectively, for patients with MATV-WB < 49.5 and MATV-WB ≥ 49.5. Patients with MATV-WB ≥ 49.5 had a mortality risk 2.9-5.8 times higher than those with MATV-WB < 49.5 (HR = 4.12, p < 0.001). MATV-WB cutoff points were also determined for each cTNM stage: 23.7(I), 49.5(II), 52(III), 48.8(IV) (p = 0.029, p = 0.227, p = 0.025 and p = 0.001, respectively). At stages I, III and IV there was a statistically-significant difference in the estimated mean overall survival time between groups of patients defined by the cutoff points (p = 0.007, p = 0.004 and p < 0.001, respectively). At stage II (p = 0.365), there was a clinically-significant difference of about 12 months between the groups. In all cTNM stages, patients with MATV-WB ≥ cutoff points had lower survival rates. Combined clinical TNM-PET staging (cTNM-P) was then tested: Stage I < 23.7; Stage I �

Stage III colon cancer is currently treated as an entity with a unified therapeutic principle. The aim of the retrospective study is to explore the clinicopathological characteristics and outcomes of site-specific stage III colon cancers and the influences of tumor location on prognosis. Eight hundred ninety-five patients with stage III colon cancer treated with radical operation and subsequent adjuvant chemotherapy (5-fluorouracil/oxaliplatin) were divided into seven groups according to colon segment (cecum, ascending colon, hepatic flexure, transverse colon, splenic flexure, descending colon, and sigmoid colon). Expression of excision repair cross-complementing group 1 (ERCC1) and thymidylate synthase (TS) was examined by immunohistochemistry. We assessed if differences exist in patient characteristics and clinic outcomes between the seven groups. There were significant differences in tumor differentiation (P Cancer (AJCC) tumor-node-metastasis (TNM) stage (P colon. Cox regression analyses identified that tumor location was an independent prognostic factor for RFS and OS. Stage III colon cancer located proximally carried a poorer survival than that located distally. Different efficacies of FOLFOX adjuvant chemotherapy may be an important factor affecting survival of site-specific stage III colon cancers.

Fifty-two patients with pathologic stage III Hodgkin's disease were studied in an effort to determine whether location of involved abdominal nodes influenced survival. Treatment consisted of total nodal radiotherapy with or without subsequent combination chemotherapy. The initial radiation field was the ''extended mantle,'' which included supradiaphragmatic nodes, the splenic hilar area, and paraaortic nodes to the level of L2-L4. Subsequently, lower paraaortic and iliac regions were treated (''lower inverted Y''). Patients with disease limited to the spleen and/or splenic, celiac, or portal nodes (''anatomic substage'' III/sub 1/) had a more favorable 5-yr survival than did patients with involvement of paraaortic, iliac, or mesenteric nodes (''anatomic substage'' III/sub 2/) : 93% versus 57%, respectively (p < 0.05). The addition of combination chemotherapy to total nodal irradiation was associated with improved survival of patients in stage III/sub 2/, but not of those in stage III/sub 1/.

This study aimed to analyse the feasibility and acute toxicity of radical hypo-fractionated radiotherapy (RT) for elderly patients with non-small-cell lung cancer (NSCLC). We conducted a retrospective evaluation of treatment with volumetric modulated arc therapy (VMAT) of elderly patients affected by stage III inoperable NSCLC. The dose prescription was 56 Gy in 20 fractions, 55 Gy in 22 fractions, or 50 Gy in 20 fractions. Target volume included only the primary lesion and the infiltrated lymph nodes. The primary end point was acute and late toxicity, while secondary end points were progression-free survival (PFS), and overall survival (OS). In all, 41 patients were included in this analysis. The mean age of the patients was 78.6 years, and 22 patients had staged IIIA while 19 patients had stage IIIB disease. All but one patient had pathological nodal involvement; 15 patients received chemotherapy before RT. Acute grade 1-2 toxicity was recorded in 25 (61%) patients. Late toxicity was recorded in 13 (32%) patients. No cases of G3 or G4 toxicity were recorded. Complete response was obtained in two (5%) patients, 26 (63%) showed a partial response, and two (5%) experience disease progression. At a mean follow-up of 9.9 months (range, 1.1-25.4), 17 patients had died from disease progression, one died from other causes, and 23 were alive. Median OS was 13.7 ± 1.5 months (95% CI: 10.7-16.7), OS at 12 and 18 months was 51.3 ± 9.5% and 35.1 ± 10.1%, respectively. Median PFS was 13.7 ± 2.3 months (95% CI: 9.1-18.2), and PFS at 12 and 18 months was 50.1 ± 9.9% and 38.9 ± 10.4%, respectively. Radical hypo-fractionated VMAT is a promising treatment for locally advanced NSCLC in the elderly. The use of hypo-fractionated radiotherapy for lung cancer in older patients can be considered a valuable approach, particularly for patients with poor performance status or refusing other treatment approaches.

Many patients with non-small cell lung cancer (NSCLC) die within the first few years of diagnosis, and considerable excess mortality remains even after 5 years. We investigated the death rate and the distribution of causes of death for NSCLC patients by age and stage at diagnosis during long-term follow-up. All 72 021 patients aged 45-89 years diagnosed with stage I-III NSCLC between 1989 and 2008 in the Netherlands and who died up till 2011 were derived from the Netherlands Cancer Registry and linked with the database of Statistics Netherlands for underlying causes of death. Mortality ratios and proportional distribution of causes of death were calculated during 5 time periods after diagnosis of NSCLC (up to 15 years). Median follow-up was 9.6 years (range: 0-23 years). Lung cancer was the predominant cause of death in the first 6 years after diagnosis (being 80%-85% and ∼90% up to 3 years for localized and locally advanced disease, respectively, and ∼60%-75% and ∼75%-85% during years 4-6 for both stage groups, respectively). Thereafter, lung cancer as cause of death proportionally decreased with time since diagnosis, but remained over 30%. Hence, cardiovascular diseases and chronic obstructive pulmonary diseases (COPD) became more important causes of death, especially for patients aged >60 years at diagnosis (up to 34% for cardiovascular diseases and up to 19% for COPD). With time, the relative contribution of cardiovascular and COPD causes of death increased, although the absolute contribution of lung cancer remained high in non-metastatic NSCLC. Therefore, managing morbidity of these diseases remains relevant. © The Author 2015. Published by Oxford University Press on behalf of the European Society for Medical Oncology. All rights reserved.

Patients with pathological stage IA adenocarcinoma (AC) have a variable prognosis, even if treated in the same way. The postoperative treatment of pathological stage IA patients is also controversial. We identified 176 patients with pathological stage IA AC who had undergone a lobectomy and mediastinal lymph node dissection at the Shanghai Chest Hospital, Shanghai, China, between 2000 and 2006. No patient had preoperative treatment. The histologic subtypes of all patients were classified according to the 2011 International Association for the Study of Lung Cancer (IASLC)/American Thoracic Society (ATS)/European Respiratory Society (ERS) international multidisciplinary lung AC classification. Patients' 5-year overall survival (OS) and 5-year disease-free survival (DFS) were calculated using Kaplan-Meier and Cox regression analyses. One hundred seventy-six patients with pathological stage IA AC had an 86.6% 5-year OS and 74.6% 5-year DFS. The 10 patients with micropapillary predominant subtype had the lowest 5-year DFS (40.0%).The 12 patients with solid predominant with mucin production subtype had the lowest 5-year OS (66.7%). Univariate and multivariate analysis showed that sex and prognositic groups of the IASLC/ATS/ERS histologic classification were significantly associated with 5-year DFS of pathological stage IA AC. Our study revealed that sex was an independent prognostic factor of pathological stage IA AC. The IASLC/ATS/ERS classification of lung AC identifies histologic categories with prognostic differences that could be helpful in clinical therapy.

The results and problems of radiotherapy were analyzed in 57 lung cancer patients more than 65 years of age (average age: 74.8 years). Of these, 45 (79%) were irradiated with a total dose exceeding 40 Gy. In these patients, the median survival was 13 months for Stages I and II, 6.5 months for Stage III, and 5 months for Stage IV. The results of combined radiotherapy and chemotherapy were better than those of radiotherapy alone. Also, slightly better results were obtained in patients treated with split-course than continuous-course irradiation. In aged lung cancer patients the prognosis was highly influenced by their respiratory function. Double cancers were present in 9 (16%) of the 57 patients. (author)

A 25-year (1970-1995) experience in clinical employment of original and improved techniques of radiation treatment in the management of more than 12,000 lung cancer patients is assessed. The employment of the new methods of radiotherapy of operable stage III squamous-cell lung cancer patients increased their 5-year survival rate from 8±3% to 42±5%, and that of inoperable stage II-III patients - from 5 to 9%. An original method of chemoradiotherapy of stage II-III small-cell cancer enabled to raise 5-year survival rate from 4 to 12%. Owing to the reduction in the number of patients declining special treatment (from 32 to 13.7%) and widening the range of indications to treatment (from 65 to 83%) the rate of clinical group II lung cancer patients administered special treatment rose more than twice (from 32.4 to 69.3%) over the past 15 years. The proportion of lung cancer patients among all cancer patients being on the register for more than 5 years in the Republic of Belarus increased more than 3-fold (from 8 to 26.7%) over the past 20 years

Objectives: Patients with severe chronic obstructive pulmonary disease (COPD) have a high risk of lung cancer and of postsurgical complications. We studied outcomes after stereotactic body radiotherapy (SBRT) in patients with severe COPD, as defined by Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria, and performed a systematic review of the literature on outcomes after SBRT or surgery in these patients. Methods: A single-institution cohort of 176 patients with COPD GOLD III-IV and Stage I non–small-cell lung cancer (NSCLC) treated with SBRT was evaluated. A systematic review identified studies reporting outcomes after SBRT or surgery for Stage I NSCLC in patients with GOLD III-IV or a predicted postoperative forced expiratory volume in 1 second (FEV1) of ≤40%. Results: In the single-institution cohort, median follow-up was 21 months and median overall survival (OS) was 32 months. Actuarial 3-year local control was 89%, and 1- and 3-year OS were 79% and 47%, respectively. COPD severity correlated with OS (p = 0.01). The systematic review identified four other studies (two surgical, two SBRT, n = 196 patients). SBRT studies were published more recently and included older patients than surgical studies. Mean 30-day mortality was 0% post-SBRT and 10% after surgery. Local or locoregional control was high (≥89%) after both treatments. Post-SBRT, actuarial OS was 79–95% at 1 year and 43–70% at 3 years. Postsurgical actuarial OS was 45–86% at 1 year and 31–66% at 3 years. Conclusions: SBRT and surgery differ in risk of 30-day mortality in patients with severe COPD. Despite the negative selection of SBRT patients, survival at 1 and 3 years is comparable between the two treatments.

The rate of radiation pneumonitis (RP) for patients receiving chemoradiotherapy has been various across studies. Whether it is related to different chemotherapy schedules used in combination with radiation therapy were evaluated in this study. New factors associated with RP were also investigated. A total of 369 consecutive patients with Stage III non small cell lung cancer treated with chemoradiotherapy were followed after radiotherapy (RT). Among them 262 patients received concurrent chemoradiotherapy followed by consolidation chemotherapy and 107 patients received only sequential chemotherapy after RT. RP was graded according to Common Terminology Criteria for Adverse Events version 4.0. The rate of grade ≥ 2 were 39.7%, 31% and 33.6% in the concurrent DP (docetaxel/cisplatin), concurrent NP (vinorelbine/cisplatin) and sequential group, and grade ≥ 3 RP were 18.4%, 9.5%, and 11.2% respectively. The rate of grade ≥ 3 RP was significantly higher in concurrent DP group than that in concurrent NP group (p = 0.04). RP occurred earlier in concurrent DP group than that in the other two groups. There were no significant differences in response rate among the three groups. In the multivariate analysis, age (OR = 1.99, p = 0.038 and OR = 8.90, p < 0.001), chemotherapy schedule (OR = 1.45, p = 0.041 and OR = 1.98, p = 0.013), mean lung dose(OR = 1.42, p < 0.001 and OR = 1.64, p < 0.001), and planning target volume(OR = 1.004, p = 0.001 and OR = 1.005, p = 0.021) were predictors for both grade ≥ 2 and grade ≥ 3 RP. Response to treatment was a new predictor for grade ≥ 3 RP only (OR = 4.39, p = 0.034). Response to treatment was found to be a new predictor for grade ≥ 3 RP. Compared to concurrent NP schedule, concurrent DP schedule achieved similar response to treatment but resulted in a higher risk of grade ≥ 3 RP

  BACKGROUND: Disparities in care have been documented for foreign-born cancer patients in the United States. However, few data are available regarding patients with lung and colorectal cancer. In the current study, the authors assessed whether patient-reported quality and receipt of recommended...... from 2003 through 2005. Logistic regression was used to assess the association between nativity and patient-reported quality of care and receipt of recommended treatments (adjuvant chemotherapy for stage III colon cancer, adjuvant chemotherapy and radiotherapy for stage II/III rectal cancer......, and curative surgery for stage I/II non-small cell lung cancer). The authors also assessed whether language explained any differences in care by nativity. RESULTS: Overall, 46% of patients reported excellent care, but foreign-born patients were less likely than US-born patients to report excellent quality...

Purpose: Proton therapy has been shown to reduce radiation dose to organs at risk (OAR) and could be used to safely escalate the radiation dose. We analyzed outcomes in a group of phase 2 study patients treated with dose-escalated proton therapy with concurrent chemotherapy for stage 3 non-small cell lung cancer (NSCLC). Methods and Materials: From 2009 through 2013, LU02, a phase 2 trial of proton therapy delivering 74 to 80 Gy at 2 Gy/fraction with concurrent chemotherapy for stage 3 NSCLC, was opened to accrual at our institution. Due to slow accrual and competing trials, the study was closed after just 14 patients (stage IIIA, 9 patients; stage IIIB, 5 patients) were accrued over 4 years. During that same time period, 55 additional stage III patients were treated with high-dose proton therapy, including 7 in multi-institutional proton clinical trials, 4 not enrolled due to physician preference, and 44 who were ineligible based on strict entry criteria. An unknown number of patients were ineligible for enrollment due to insurance coverage issues and thus were treated with photon radiation. Median follow-up of surviving patients was 52 months. Results: Two-year overall survival and progression-free survival rates were 57% and 25%, respectively. Median lengths of overall survival and progression-free survival were 33 months and 14 months, respectively. There were no acute grade 3 toxicities related to proton therapy. Late grade 3 gastrointestinal toxicity and pulmonary toxicity each occurred in 1 patient. Conclusions: Dose-escalated proton therapy with concurrent chemotherapy was well tolerated with encouraging results among a small cohort of patients. Unfortunately, single-institution proton studies may be difficult to accrue and consideration for pragmatic and/or multicenter trial design should be considered when developing future proton clinical trials.

Purpose: A Phase I study to determine a recommended dose of thoracic radiotherapy using accelerated hyperfractionation for unresectable non-small-cell lung cancer was conducted. Methods and Materials: Patients with unresectable Stage III non-small-cell lung cancer were treated intravenously with carboplatin (area under the concentration curve 2) and paclitaxel (40 mg/m{sup 2}) on Days 1, 8, 15, and 22 with concurrent twice-daily thoracic radiotherapy (1.5 Gy per fraction) beginning on Day 1 followed by two cycles of consolidation chemotherapy using carboplatin (area under the concentration curve 5) and paclitaxel (200 mg/m{sup 2}). Total doses were 54 Gy in 36 fractions, 60 Gy in 40 fractions, 66 Gy in 44 fractions, and 72 Gy in 48 fractions at Levels 1 to 4. The dose-limiting toxicity, defined as Grade {>=}4 esophagitis and neutropenic fever and Grade {>=}3 other nonhematologic toxicities, was monitored for 90 days. Results: Of 26 patients enrolled, 22 patients were assessable for response and toxicity. When 4 patients entered Level 4, enrollment was closed to avoid severe late toxicities. Dose-limiting toxicities occurred in 3 patients. They were Grade 3 neuropathy at Level 1 and Level 3 and Grade 3 infection at Level 1. However, the maximum tolerated dose was not reached. The median survival time was 28.6 months for all patients. Conclusions: The maximum tolerated dose was not reached, although the dose of radiation was escalated to 72 Gy in 48 fractions. However, a dose of 66 Gy in 44 fractions was adopted for this study because late toxicity data were insufficient.

A total of 122 patients with non-resectable lung cancer, comprising 98 with non-small cell lung cancer (NSCLC) and 24 with small cell lung cancer (SCLC), who were treated from November 1976 through December 1985 with definitive radiation therapy (RT), were retrospectively analyzed for the outcome of RT. Overall, the 5-year survival rate was 6 %: it was 8 % for SCLC and 4 % for NSCLC. For NSCLC, survival was significantly better in stages I-III patients than stage IV patients (p < 0.01), although it was independent of histology, the combination of chemotherapy, and fractionation schedule. Local recurrence and distant metastasis were found to be the cause of death in 42 % and 13 %, respectively, in the stages I-II NSCLC group; and in 19 % and 52 %, respectively, in the SCLC group. The SCLC patients tended to have better survival when given chemotherapy before RT. Ten patients surviving for three years or more were characterized by having early stage of NSCLC, less than 100 cm of irradiated field, and a total dose of 60 Gy or more. Twelve patients (10 %) had severe radiation pneumonitis that resulted in death. Acute and fetal pneumonitis tended to be frequent when chemotherapy was combined with RT. (Namekawa, K.)

To evaluate the effectiveness and tolerance of the postoperative radiation therapy for patients with Stage III thymoma and to define the optimal radiotherapeutic regimen. We retrospectively analyzed the records of 24 patients with Stage III thymoma who were referred for postoperative radiation therapy in our institution from June, 1987 to May, 1999. Surgical therapy consisted of total resection in one patient, subtotal resection in seventeen, and biopsy alone in six patients. Age of the patients was ranged from 20 to 62 years with mean age of 47 years. Male to female ratio was 14 to 10. Radiation therapy was delivered with linear accelerator producing either 6 MeV or 10 MeV photons. The irradiated volume included anterior mediastinum and known residual disease. The supraclavicular fossae were not irradiated. The delivered total dose was ranged from 30 to 56 Gy. One patient received 30 Gy and eighteen patients received minimum of 50 Gy. Follow up period was ranged from 12 months to 8 years with median follow up of 40 months. The overall local control rate for entire group of patients was 67% at 5 years. The cumulative local failure rates at one, three and five year were 18%, 28% and 33%, respectively. In patients treated with subtotal resection and biopsy alone, local control rate was 76% and 33%, respectively. The actuarial observed survival rate at 5 years was 57%, and actuarial adjusted survival at 5 years was 72%. The difference between 5 year survival rates for patients treated with subtotal resection and biopsy alone was not statistically significant (62% vs 30%). We might conclude that postoperative radiation therapy was safe and effective treatment for patients with Stage III thymoma. Postoperative radiation therapy is recommended in cases where tumor margin is close or incomplete resection is accomplished

IMRT and 3-dimensional conformal radiotherapy (3-DCRT) plans of 25 patients with non-small cell lung (NSCLC) were compared in terms of planning target volume (PTV) coverage and sparing of functional lung (FL) defined by a SPECT perfusion scan. IMRT resulted in significant reduction of functional V 20 and mean lung dose in stage III patients with inhomogeneous hypoperfusion. If the dose to FL is shown to be the determinant of lung toxicity, IMRT would allow for effective dose escalation by specific avoidance of functional lung.

The majority of stage III patients with non-small cell lung cancer (NSCLC) are unsuitable for concurrent chemoradiotherapy, the non-surgical gold standard of care. As the alternative treatment options of sequential chemoradiotherapy and radiotherapy alone are associated with high local failure rates, various intensification strategies have been employed. There is evidence to suggest that altered fractionation using hyperfractionation, acceleration, dose escalation, and individualisation may be of benefit. The MAASTRO group have pioneered the concept of 'isotoxic' radiotherapy allowing for individualised dose escalation using hyperfractionated accelerated radiotherapy based on predefined normal tissue constraints. This study aims to evaluate whether delivering isotoxic radiotherapy using intensity modulated radiotherapy (IMRT) is achievable. Isotoxic IMRT is a multicentre feasibility study. From June 2014, a total of 35 patients from 7 UK centres, with a proven histological or cytological diagnosis of inoperable NSCLC, unsuitable for concurrent chemoradiotherapy will be recruited. A minimum of 2 cycles of induction chemotherapy is mandated before starting isotoxic radiotherapy. The dose of radiation will be increased until one or more of the organs at risk tolerance or the maximum dose of 79.2 Gy is reached. The primary end point is feasibility, with accrual rates, local control and overall survival our secondary end points. Patients will be followed up for 5 years. The study has received ethical approval (REC reference: 13/NW/0480) from the National Research Ethics Service (NRES) Committee North West-Greater Manchester South. The trial is conducted in accordance with the Declaration of Helsinki and Good Clinical Practice (GCP). The trial results will be published in a peer-reviewed journal and presented internationally.

Current Status of Stereotactic Ablative Radiotherapy (SABR for Early-stage 
Non-small Cell Lung Cancer

Directory of Open Access Journals (Sweden)

Anhui SHI

2016-06-01

Full Text Available High level evidence from randomized studies comparing stereotactic ablative radiotherapy (SABR to surgery is lacking. Although the results of pooled analysis of two randomized trials for STARS and ROSEL showed that SABR is better tolerated and might lead to better overall survival than surgery for operable clinical stage I non-small cell lung cancer (NSCLC, SABR, however, is only recommended as a preferred treatment option for early stage NSCLC patients who cannot or will not undergo surgery. We, therefore, are waiting for the results of the ongoing randomized studies [Veterans affairs lung cancer surgery or stereotactic radiotherapy in the US (VALOR and the SABRTooth study in the United Kingdom (SABRTooths]. Many retrospective and case control studies showed that SABR is safe and effective (local control rate higher than 90%, 5 years survival rate reached 70%, but there are considerable variations in the definitions and staging of lung cancer, operability determination, and surgical approaches to operable lung cancer (open vs video-assisted. Therefore, it is difficult to compare the superiority of radiotherapy and surgery in the treatment of early staged lung cancer. Most studies demonstrated that the efficacy of the two modalities for early staged lung cancer is equivalent; however, due to the limited data, the conclusions from those studies are difficult to be evidence based. Therefore, the controversies will be focusing on the safety and invasiveness of the two treatment modalities. This article will review the ongoing debate in light of these goals.

Background: Stereotactic body radiation therapy (SBRT) represents a substantial paradigm shift in the treatment of patients with medically inoperable Stage I/II non-small-cell lung cancer. We reviewed our experience using either three- or five-fraction SBRT for peripheral or central tumors, respectively. Methods and Materials: A total of 91 patients signed an institutional review board-approved consent form, were treated with SBRT, and have had ≥6 months of follow-up. Patients were referred for SBRT because of underlying comorbidities (poor performance status in 31 or poor lung function in 52) or refusal of surgery (8 patients). Of the cancers, 83 were peripheral and eight were central. Peripheral cancers received a mean dose of 18 Gy x three fractions. Cancers within 2 cm of the bronchus, esophagus, or brachial plexus were treated with 9 Gy x five fractions. Results: The median follow-up duration for these patients was 18 months (range, 6-42 months). TNM staging was as follows: 58 patients with T1N0M0, 22 with T2N0M0, 2 with T3N0M0 (chest wall), and 6 with T1N0M1 cancers. The median tumor diameter was 2 cm (range, 1-5 cm). The median forced expiratory volume in 1 s was 46% (range, 17-133%) and the median carbon monoxide diffusing capacity (DLCO) was 49% (range, 15-144%). Two-year local tumor control was achieved in 86% of patients. The predominant pattern of failure was the development of distant metastasis or second lung cancer. The development of distant metastasis was the only significant prognostic factor for overall survival on multivariate analysis. Conclusions: Local tumor control was shown to be high using SBRT for non-small-cell lung cancer. Overall survival is highly coerrelated with the development of distant metastasis.

Health-care costs associated with pressure sores are significant and their financial burden is likely to increase even further. The aim of this study was to analyse the direct medical costs of hospital care for surgical treatment of pressure sores stage III and IV. We performed a retrospective chart study of patients who were surgically treated for stage III and IV pressure sores between 2007 and 2010. Volumes of health-care use were obtained for all patients and direct medical costs were subsequently calculated. In addition, we evaluated the effect of location and number of pressure sores on total costs. A total of 52 cases were identified. Average direct medical costs in hospital were €20,957 for the surgical treatment of pressure sores stage III or IV; average direct medical costs for patients with one pressure sore on an extremity (group 1, n = 5) were €30,286, €10,113 for patients with one pressure sore on the trunk (group 2, n = 32) and €40,882 for patients with multiple pressure sores (group 3, n = 15). The additional costs for patients in group 1 and group 3 compared to group 2 were primarily due to longer hospitalisation. The average direct medical costs for surgical treatment of pressure sores stage III and IV were high. Large differences in costs were related to the location and number of pressure sores. Insight into the distribution of these costs allows identification of high-risk patients and enables the development of specific cost-reducing measures.

2003-01-01

Lung cancer is the leading cause of death among malignant tumors in Japan and statisticians predict that the death rate by lung cancer will increase twice or 2.5 times within 10 years. Early detection and early resection are the first task to decrease the death rate, and radiotherapy and chemotherapy should be improved. In this paper, the present status of surgical treatment for lung cancer was summarized and the possibility of heavy ion therapy for lung cancer was discussed in comparison with surgical result. Overall 5-year survival rates in stages I, II, III and IV were 78%, 42% 29% and 16% respectively. The survival rate in stage I was correlated with tumor size and that in lung cancer of tumor size 2 cm or less was about 90%. If lung cancer is found at early stage, lung cancer can be cured. Limitation of detection of lung cancer is 2.3 mm in hilar squamous cell carcinoma by autofluorescence bronchoscopy and 5-10 mm in peripheral adenocarcinoma by high resolution CT. Less invasive surgery by video-assisted thoracoscopic surgery was applied to stage I lung cancer and the result was satisfactory. However, most lung cancer patients are heavy smokers with underlying lung diseases including chronic obstructive plumonary disease (COPD) and there are many patients not indicative for less invasive surgery. Preliminary results of heavy ion therapy showed remarkable improvement compared with that with conventional radiation therapy. Three-year survival rate of stage I in Protocol 9802 is 80%, almost the same with that in surgical result, indicating the possibility becoming the established therapeutic modality in stage I lung cancers, in patients with marginal biological function for surgical treatment, in particular.

Surgical resection remains as the treatment of choice for non-small cell lung cancer (NSCLC) and provides the best opportunity for cure and long-term survival. Minimally invasive percutaneous ablative therapies, such as radiofrequency ablation (RFA) for treating lung cancers, are currently being studied as treatment alternatives. But, to date, there is little information on comparison of therapeutic effects between surgery and RFA in patients with early stage lung malignancy. We aimed to investigate the clinical significance of RFA as an alternative curative modality for the early stage lung cancer through analyzing the long-term mortality of both treatment groups; surgery vs. RFA. Twenty-two patients of stage I NSCLC were included for this comparative analysis. To minimize confounding effects, we conducted a matching process. In which patients of RFA group (n = 8) were matched with patients of surgery group (n = 14) on the following variables; gender, age (±3 years), tumor node metastasis stage, and calendar year of surgery or RFA (±2 years). The mean survival duration of RFA group and surgery group were 33.18 ± 7.90 and 45.49 ± 7.21, respectively (months, p = 0.297). Log-rank analysis showed that there was no significant difference in overall survival (p = 0.054) between two groups. These results have shown that RFA can offer the survival comparable to that by surgery to stage I NSCLC patients, especially to the patients impossible for the surgery. This study provides an evidence for the use of RFA as a treatment alternative with low procedural morbidity for inoperable early-stage NSCLC patients.

Induction chemotherapy for locoregional lung cancer using paclitaxel combination. A preliminary report

2000-01-01

Induction chemotherapy has been reported to be effective in treatment of locally advanced, borderline resectable, (Stage III), non small cell lung carcinoma (NSCLC). A logical extension of the indication for the induction chemotherapy may be to treat earlier stage resectable lung cancers (stages I and II) because the cure rate of the resectable lung cancers still remains poor and is below 60% except for stage I A. Thirty eight patients with a diagnosis of loco-regional NSCLC were treated with paclitaxel combination chemotherapy. Following two courses of induction chemotherapy, patients underwent surgical therapy whenever possible. There ten patients with stage I disease, four patients with stage II, 13 with stage IIIA, nine had stage IIIB, and two with stage IV. An overall response rate of 74% was observed. The response rate for 14 resectable patients (stage I and II) was 86%. The chemotherapy regimen was well tolerated and apart from one instance of anaphylaxis, no serious side effects were observed

Up to 15% of colorectal cancers exhibit microsatellite instability (MSI), where errors in replication go unchecked due to defects in the mismatch repair system. This study aimed to determine survival in a large single-centre series of 1250 consecutive colorectal cancers subjected to universal MSI testing. Clinical and pathological features of patients with colorectal cancer identified on prospectively maintained colorectal and pathology databases at St. Vincent's University Hospital from 2004 to May 2012 were examined. Mismatch repair (MMR) status was determined by immunohistochemistry. Kaplan-Meier curves, the log-rank test and Cox regression were used to associate survival with clinical and pathological characteristics. Of the 1250 colorectal cancers in the study period, 11% exhibited MSI (n = 138). Patients with MSI tumours had significantly lower rates of lymph node and distant metastases (MSI N+ rate: 24.8% compared with MSS N+ rate: 46.2%, p colon cancer. However, patients with Stage III MSI colon cancers had a worse DSS than those with MSS tumours. Stage III MSI tumours exhibited higher rates of lymphovascular invasion and perineural invasion than Stage I/II MSI tumours. MSI is associated with a reduced risk of nodal and distant metastases, with an improved DSS in Stage I/II colon cancer. However, when MSI tumours progress to Stage III these patients had worse outcomes and pathological features. New strategies for this cohort of patients may be required to improve outcomes.

Full Text Available Background: Adjuvant therapy after curative resection is associated with survival benefit in stage III pancreatic cancer. We analyzed the factors affecting the outcome of adjuvant therapy in stage III pancreatic cancer and compared overall survival with different modalities of adjuvant treatment. Methods: This is a retrospective study of patients with stage III pancreatic cancer listed in the National Cancer Database (NCDB who were diagnosed between 2004 and 2012. Patients were stratified based on adjuvant therapy they received. Unadjusted Kaplan-Meier and multivariable Cox regression analysis were performed. Results: We analyzed a cohort included 1731 patients who were recipients of adjuvant therapy for stage III pancreatic cancer within the limits of our database. Patients who received adjuvant chemoradiation had the longest postdiagnosis survival time, followed by patients who received adjuvant chemotherapy, and finally patients who received no adjuvant therapy. On multivariate analysis, advancing age and patients with Medicaid had worse survival, whereas Spanish origin and lower Charlson comorbidity score had better survival. Conclusions: Our study is the largest trial using the NCDB addressing the effects of adjuvant therapy specifically in stage III pancreatic cancer. Within the limits of our study, survival benefit with adjuvant therapy was more apparent with longer duration from date of diagnosis.

The incidence of lung cancer among individuals infected with the human immunodeficiency virus (HIV) is elevated compared to that among the general population. This study examines the prevalence of HIV and its impact on outcomes among Medicare beneficiaries who are 65 years of age or older and were diagnosed with non small cell lung cancer (NSCLC) between 1997 and 2008. Prevalence of HIV was estimated using the Poisson point estimate and its 95% confidence interval. Relative risks for potential risk factors were estimated using the log-binomial model. A total of 111,219 Medicare beneficiaries met the study criteria. The prevalence of HIV was 156.4 per 100,000 (95% CI: 140.8 to 173.8) and has increased with time. Stage at NSCLC diagnosis did not vary by HIV status. Mortality rates due to all causes were 44%, 76%, and 88% for patients with stage I/II, III, and IV NSCLC, respectively. Across stages of disease, there was no difference between those who were HIV-infected and those who were not with respect to overall mortality. HIV patients, however, were more likely to die of causes other than lung cancer than their immunocompetent counterparts.

Purpose: to report the results of a prospective randomized study concerning the role of radiotherapy in the treatment of stage III, unresectable, asymptomatic non-small cell lung cancer. Material and methods: between 1992 and 1996, 240 patients with stage III, unresectable, asymptomatic non-small cell lung cancer were enrolled in this study, and sequentially randomized to one of the three treatment arms: conventional irradiation, hypo-fractionated irradiation and control group. In the conventional irradiation arm (79 patients), a dose of 50 Gy in 25 fractions in five weeks was delivered to the primary tumor and the mediastinum. In the hypo-fractionated irradiation arm (81 patients), there were two courses of irradiation separated by an interval of four weeks. In each series, patients received 20 Gy in five fractions in five days, in the same treatment volume as the conventional irradiation group. in the control group arm, 80 patients initially did not receive radiotherapy and were only observed. Delayed palliative hypo-fractionated irradiation (20-25 Gy in four to five fractions in four to five days) was given to the primary tumor when major symptoms developed. Results: the two-year actuarial survival rates for patients in the conventional irradiation, hypo-fractionated irradiation and control group arms were 18%, 6% and 0%, with a median survival time of 12 months, nine months and six months respectively. The differences between survival rates were statistically significant at the 0.05 level. Conclusion: although irradiation provides good palliation the results are disappointing. The comparison of conventional and hypo-fractionated irradiation shows an advantage for conventional schedules. (author)

1985-04-01

Since increased synthesis of collagen has been demonstrated in tissue of type IV gastric cancer, we attempted to distinguish type IV gastric cancer from other cancers by measuring serum levels of type III procollagen N-terminal peptide (type III-N-peptide). Mean serum levels in type IV gastric cancer patients without metastasis were found to be elevated above normal values and developed a tendency to be higher than those in types I, II and III gastric cancer patients without metastasis. Highly positive ratios were found in patients with liver diseases including hepatoma and colon cancer, biliary tract cancer, and esophageal cancer patients with liver, lung or bone metastasis, but only 2 out of 14 of these cancer patients without such metastasis showed positive serum levels of type III-N-peptide. Positive cases in patients with type IV gastric cancer were obtained not only in the group with clinical stage IV but also in the groups with clinical stages II and III. In addition, high serum levels of type III-N-peptide in patients with type IV gastric cancer were seen not only in the cases with liver, lung or bone metastasis but also in cases with disseminated peritoneal metastasis alone. These results suggest that if the serum level of type III-N-peptide is elevated above normal values, type IV gastric cancer should be suspected after ruling out liver diseases, myelofibrosis and liver, lung or bone metastasis.

OBJECTIVE: Mediastinal staging is of paramount importance prior to surgery for non-small-cell lung cancer (NSCLC) to identify patients with N2-disease. Mediastinoscopy remains the gold standard, and sampling from at least three lymph node stations is generally recommended. It is unknown whether...

The role of medical imaging in staging and followup of primary lung cancers

International Nuclear Information System (INIS)

Bragg, D.G.

1986-01-01

There has been a significant improvement in the rate of resectability of lung cancers, a situation that has resulted from improved preoperative staging. A large measure of this improvement has resulted from the application of CT and more recently, magnetic resonance imaging in this pre-surgical staging process. The application and evaluation of these imaging procedures has resulted in significant controversy. The size criteria of lymph nodes chosen in defining the abnormal mediastinal lymph node is responsible for part of the controversy. If the lymph node size is set below 2.0 cm, a higher false-positive rate must be accepted. In addition, chest wall extension is often inaccurately assessed with CT as is mediastinal invasion. The status of CT and MRI in staging the patient with lung cancer prior to surgery will be discussed in detail. It should be remembered that the ultimate goal of radiographic procedures in this staging process should be in determining which patients need mediastinoscopy prior to surgery and not in attempting to exclude patients from surgery. The appropriate formula for the application of CT and MRI will also be included. Finally, a recommendation for the post-treatment followup of the patient with lung cancer will also be presented.

Purpose: Concomitant chemoradiotherapy (CRT) increases survival rates compared with radical radiotherapy alone (RT) in Stage III non-small-cell lung cancer (NSCLC), as a result of improved local control. The effect of CRT on local control in Stage I NSCLC is less well documented. We retrospectively reviewed local control and survival following CRT or RT for inoperable Stage I NSCLC patients. Methods and materials: Eligible patients had histologically/cytologically proved inoperable Stage I NSCLC and had undergone complete staging investigations including an F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) scan. Radiotherapy was planned as (1) 60 Gy in 30 fractions over 6 weeks with or without concomitant chemotherapy or (2) 50-55 Gy in 20 fractions without chemotherapy. Results: Between 2000 and 2005, 73 patients met the eligibility criteria and were treated as follows: CRT (60 Gy)-39; RT (60 Gy)-23; RT (50-55 Gy)-11. The median follow-up time for all patients was 18 months (range, 1-81 months). Survival analysis was based on intent to treat. Local progression-free survival (PFS) at 2 years was 66% with CRT and 55% with RT. The 2-year distant PFS was 60% following CRT and 63% after RT. The 2-year PFS rates were 57% and 50%, respectively. The 2-year survival rate for patients treated with CRT was 57% and 33% in patients receiving RT. Conclusions: Despite the use of CRT and routine staging with FDG-PET, both local and distant recurrences remain important causes of treatment failure in patients with inoperable stage I NSCLC.

To identify the variability of short- and long-term survival outcomes among closed Phase III randomized controlled trials with small sample sizes comparing SBRT (stereotactic body radiation therapy) and surgical resection in operable clinical Stage I non-small cell lung cancer (NSCLC) patients. Clinical Stage I NSCLC patients who underwent surgery at our institution meeting the inclusion/exclusion criteria for STARS (Randomized Study to Compare CyberKnife to Surgical Resection in Stage I Non-small Cell Lung Cancer), ROSEL (Trial of Either Surgery or Stereotactic Radiotherapy for Early Stage (IA) Lung Cancer), or both were identified. Bootstrapping analysis provided 10,000 iterations to depict 30-day mortality and three-year overall survival (OS) in cohorts of 16 patients (to simulate the STARS surgical arm), 27 patients (to simulate the pooled surgical arms of STARS and ROSEL), and 515 (to simulate the goal accrual for the surgical arm of STARS). From 2000 to 2012, 749/873 (86%) of clinical Stage I NSCLC patients who underwent resection were eligible for STARS only, ROSEL only, or both studies. When patients eligible for STARS only were repeatedly sampled with a cohort size of 16, the 3-year OS rates ranged from 27 to 100%, and 30-day mortality varied from 0 to 25%. When patients eligible for ROSEL or for both STARS and ROSEL underwent bootstrapping with n=27, the 3-year OS ranged from 46 to 100%, while 30-day mortality varied from 0 to 15%. Finally, when patients eligible for STARS were repeatedly sampled in groups of 515, 3-year OS narrowed to 70-85%, with 30-day mortality varying from 0 to 4%. Short- and long-term survival outcomes from trials with small sample sizes are extremely variable and unreliable for extrapolation. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Full Text Available Introduction: Patients with end-stage interstitial  lung disease (ILD do not appear to receive adequate palliative care despite apparent suffering before death. The aim of this study was to evaluate their signs, symptoms, and treatment received before death. Methods: Patients with ILD and lung cancer (LC who were hospitalized and died in our hospital were enrolled retrospectively. Signs and symptoms and treatments at 7 days, 3 days, and 1 day before death were evaluated and compared between the two groups of patients. Results: A total of 23 patients with ILD and 59 patients with LC group were eligible for participation. Significantly more LC patients had loss of consciousness than ILD patients on 7 days (ILD: LC = 1 [5.6%]:24 [41%], P = 0.013, 3 days (1 [5.6%]:33 [56%], P < 0.001. Significantly more ILD patients had dyspnea than LC patients on 3 days (16 [89%]:38 [64%], P = 0.047 1 day before death (21 [91%]:33 [56%], P = 0.001. On 1 day before death, significantly more LC patients received morphine than ILD patients (2 [8.7%]: 14 [24%], P = 0.015. More ILD patients received sedation (11 [48%]: 11 [19%], P = 0.007. Conclusions: End-stage ILD patients may experience dyspnea more frequently than terminal LC patients, and they need sedation. Morphine should be administered to ILD patients who have dyspnea. Additional prospective studies are needed.

Full text:Purpose: To evaluate the value of PET/CT in detecting occult metastases in patients with T 1 -stage non-small cell lung cancer (NSCLC). Method: Patients with proven NSCLC and T 1 -stage ( c m) were retrospectively analyzed. In all patients a whole-body 18 F-FDG PET/CT scan for initial staging was performed. The PET/CT findings were compared with all available clinical information, intra-operative findings and the histopathological results. Results: 95 patients (39 men, 56 women; age range, 19-85 years) were analyzed in our study. PET/CT in 68-95 patients correctly excluded mediastinal and distant metastases. In 17/95 patients (18%) mediastinal lymph-node metastases were proven (N 2 n=15; N 3 n=2). PET/CT correctly detected in 10/17 patients (58.8%) mediastinal nodal disease. The smallest mediastinal lymph-node metastasis detected by PET/CT had a size of 0.7 c m. In 7 patients PET/CT missed N 2 -stage. In three of these patients the SUVmax of the primary was c m. Only in one missed N 2 -stage metastasis was sized > 1.0 c m. The tumor histology (adenocarcinoma, squamous cell carcinoma) and location of the primary (central, periphery) did not influence the missed N 2 -stage by PET/CT. PET/CT diagnosed correctly N 3 -stage in 2 patients. 10/95 patients (10.5%) had distant metastases. PET/CT detected unknown M 1 -stage in 4/10 patients. In one patient a metastasis of the parietal pleura was missed by PET/CT. Conclusion: In our study, 28% patients with T 1 -stage NSCLC showed mediastinal or distant metastases. PET/CT was efficient in the detection of occult metastases. However, the sensitivity of PET/CT in mediastinal staging was only 64%.

Interpretation of recovery Stage III in gold: a comment on the paper of A. Seeger and W. Frank

The attempt of Seeger and Frank to reinterpret the annealing in recovery Stage III in gold in terms of the mobile single interstitial is discussed. Considering the experimental data of Stage III in irradiated samples and for the annealing stage observed in quenching samples around room temperature, it is concluded that the assignment of the recovery in these two stages to two different elementary defects is unjustified. It is further demonstrated that the interpretation of recovery Stage III by interstitial migration is in conflict with the direct observations of vacancies migrating in this stage and that the interpretation of the recovery measurements in radiation doped gold by the two interstitial model leads to inconsistencies. The attempt to interpret recovery Stage III in gold by interstitial migration must therefore be rejected and the activation energy of 0.71 eV measured for this stage must be attributed to the migration energy of single vacancies.

Seung, Steven K.; Ross, Helen J.

2009-01-01

Purpose: The optimal combination of chemotherapy and radiotherapy (RT) and the role of consolidation chemotherapy in patients with locally advanced non-small-cell lung cancer (NSCLC) are unknown. Topotecan is active against NSCLC, can safely be combined with RT at effective systemic doses, and can be given by continuous infusion, making it an attractive study agent against locally advanced NSCLC. Methods and Materials: In this pilot study, 20 patients were treated with infusion topotecan 0.4 mg/m 2 /d with three-dimensional conformal RT to 63 Gy both delivered Monday through Friday for 7 weeks. Patients without progression underwent consolidation chemotherapy with etoposide and a platinum agent for one cycle followed by two cycles of docetaxel. The study endpoints were treatment response, time to progression, survival, and toxicity. Results: Of the 20 patients, 19 completed induction chemoradiotherapy and 13 completed consolidation. Of the 20 patients, 18 had a partial response and 1 had stable disease after induction chemoradiotherapy. The 3-year overall survival rate was 32% (median, 18 months). The local and distant progression-free survival rate was 30% (median, 21 months) and 58% (median, not reached), respectively. Three patients developed central nervous system metastases, 1 within 228 days, 1 within 252 days, and 1 within 588 days. Three patients had pulmonary emboli. Therapy was well tolerated with 1 of 20 developing Grade 4 lymphopenia. Grade 3 hematologic toxicity was seen in 17 of 20 patients but was not clinically significant. Other Grade 3 toxicities included esophagitis in 3, esophageal stricture in 2, fatigue in 8, and weight loss in 1. Grade 3 pneumonitis occurred in 6 of 20 patients. Conclusion: Continuous infusion topotecan with RT was well tolerated and active in the treatment of poor-risk patients with unresectable Stage III NSCLC

We examined the outcomes of the first 500 patients referred to a dedicated Rapid Access Lung Cancer Clinic. A total of 206 patients (41.2%) were diagnosed with a thoracic malignancy; 179 had primary lung cancer and 27 had secondary or other thoracic cancers. Pulmonary nodules requiring ongoing surveillance were found in a further 79 patients (15.8%). Of those patients found to have primary lung cancer, 24 (13.4%) had Small Cell and 145 (81%) had Non Small Cell Lung Cancer. In patients with Non small cell tumours, 26 (21.1%) were stage 1, 14 (11.4%) stage II, 37 (30.1%) stage III and 46 (37.4%) stage IV at diagnosis. For the 129 patients (72%) in whom the thoracic MDT recommended active treatment, primary therapy was surgical resection in 44 (24.6%), combined chemoradiation in 31 patients (17.3%), chemotherapy alone in 39 (21.8%) and radiation in 15 (8.4%).

Myeloid clusters are associated with a pro-metastatic environment and poor prognosis in smoking-related early stage non-small cell lung cancer.

Full Text Available This study aimed to understand the role of myeloid cell clusters in uninvolved regional lymph nodes from early stage non-small cell lung cancer patients.Uninvolved regional lymph node sections from 67 patients with stage I-III resected non-small cell lung cancer were immunostained to detect myeloid clusters, STAT3 activity and occult metastasis. Anthracosis intensity, myeloid cluster infiltration associated with anthracosis and pSTAT3 level were scored and correlated with patient survival. Multivariate Cox regression analysis was performed with prognostic variables. Human macrophages were used for in vitro nicotine treatment.CD68+ myeloid clusters associated with anthracosis and with an immunosuppressive and metastasis-promoting phenotype and elevated overall STAT3 activity were observed in uninvolved lymph nodes. In patients with a smoking history, myeloid cluster score significantly correlated with anthracosis intensity and pSTAT3 level (P<0.01. Nicotine activated STAT3 in macrophages in long-term culture. CD68+ myeloid clusters correlated and colocalized with occult metastasis. Myeloid cluster score was an independent prognostic factor (P = 0.049 and was associated with survival by Kaplan-Maier estimate in patients with a history of smoking (P = 0.055. The combination of myeloid cluster score with either lymph node stage or pSTAT3 level defined two populations with a significant difference in survival (P = 0.024 and P = 0.004, respectively.Myeloid clusters facilitate a pro-metastatic microenvironment in uninvolved regional lymph nodes and associate with occult metastasis in early stage non-small cell lung cancer. Myeloid cluster score is an independent prognostic factor for survival in patients with a history of smoking, and may present a novel method to inform therapy choices in the adjuvant setting. Further validation studies are warranted.

Objective: To evaluate the impact of postoperative adjuvant radiotherapy, compared with surgery alone for rectal cancer. Methods: From January 1994 to October 1997, 192 patients with stage II or III rectal cancer were treated by radical resection and postoperative radiotherapy (Group S + R) and 51 patients with the same stage lesions underwent surgery alone (Group S). The median dose of radiation was 50(32-62) Gy. Kaplan-Meier method and Log-rank test were used for analysis. Results: The 5-year overall and disease-free survival rates were 60.3% and 58.3%, respectively. The overall 5-year survival rate was 59.4% in Group S + R and 64.7% in Group S, and the 5-year disease-free survival rates were 57.0% and 66.4%, respectively. There were no significant differences between either group (P=0.601 and P=0.424). The disease-free survival was not significantly prolonged in Group S + R as compared with that of Group S. The local recurrence rate was evidently reduced in Group S + R (15.8% v 26.8%, P=0.043). Conclusion: Local recurrence is a major cause of morbidity and mortality in rectal cancer. Postoperative radiotherapy, though reduces the incidence of local recurrence, does not improve the survival in the treatment of stage II and III diseases

Full Text Available Abstract Background Lung cancer is the leading cause of cancer death in the United States. Identifying factors associated with stage of diagnosis can improve our understanding of biologic and behavioral pathways of lung cancer development and detection. We used data from a prospective cohort study to evaluate associations of demographic, health history, and health behaviors with early versus late stage at diagnosis of non-small cell lung cancer (NSCLC. Methods We calculated odds ratios (ORs for the association of patient-level characteristics with advanced stage of diagnosis for NSCLC. The OR's were then adjusted for age, gender, race/ethnicity, smoking status, income, education, chronic obstructive pulmonary disease, and a comorbidity index. Results We identified 612 cases of NSCLC among 77,719 adults, aged 50 to 76 years from Washington State recruited in 2000-2002, with followup through December 2007. In univariate analyses, subjects who quit smoking Conclusions Smoking status, education, and a screening activity were associated with stage at diagnosis of NSCLC. These results may guide future studies of the underlying mechanisms that influence how NSCLC is detected and diagnosed.

Objective: To investigate the relationship between the serum level of endostatin and the clinical pathophysiological characteristics in patients with primary lung cancer. Methods: The serum levels of endostatin were detected in 48 patients with primary lung cancer and 50 patients with benign pulmonary diseases by enzyme-linked immunosorbent assay (ELISA) method. Results: Serum endostatin level in patients with primary lung cancer was significantly higher than it in patients with benign pulmonary diseases (P<0.01). It was higher in adenocarcinoma group than that in squamous cell carcinoma and small cell carcinoma group (P<0.05). The level of serum endostatin in lung cancer with TNM stage III + IV was higher than that in patients in stage I + II (P<0.01). And it was also higher in patients suffering from lung cancer with metastasis than that in patients with no metastasis (P<0.05). However, there was not a significant relation between serum endostatin level the location of the tumor and lymph node metastasis. Conclusion: Serum endostatin level in expressed higher in patients with primary lung cancer. There is significant relationship between serum endostatin level, histological classification, TNM stage and metastasis of lung cancer. (authors)

Purpose: To evaluate the survival benefit of adding vaginal brachytherapy (BT) to pelvic external beam radiation therapy (EBRT) in women with stage III endometrial cancer. Methods and Materials: The National Cancer Data Base was used to identify patients with stage III endometrial cancer from 2004 to 2013. Only women who received adjuvant EBRT were analyzed. Women were grouped according to receipt of BT. Logistic regression modeling was used to identify predictors of receiving BT. Log–rank statistics were used to compare survival outcomes. Cox proportional hazards modeling was used to evaluate the effect of BT on survival. A propensity score–matched analysis was also conducted among women with cervical involvement. Results: We evaluated 12,988 patients with stage III endometrial carcinoma, 39% of whom received EBRT plus BT. Women who received BT were more likely to have endocervical or cervical stromal involvement (odds ratios 2.03 and 1.77; P<.01, respectively). For patients receiving EBRT alone, the 5-year survival was 66% versus 69% with the addition of BT at 5 years (P<.01). Brachytherapy remained significantly predictive of decreased risk of death (hazard ratio 0.86; P<.01) on multivariate Cox regression. The addition of BT to EBRT did not affect survival among women without cervical involvement (P=.84). For women with endocervical or cervical stromal invasion, the addition of BT significantly improved survival (log–rank P<.01). Receipt of EBRT plus BT was associated with improved survival in women with positive and negative surgical margins, and receiving chemotherapy did not alter the benefit of BT. Propensity score–matched analysis results confirmed the benefit of BT among women with cervical involvement (hazard ratio 0.80; P=.01). Conclusions: In this population of women with stage III endometrial cancer the addition of BT to EBRT was associated with an improvement in survival for women with endocervical or cervical stromal invasion.

Objective: To study the efficacy and toxicity of the cyberknife in the treatment of medically inoperable patients with early stage lung cancer. Methods: From September 2006 to July 2007,17 patients with clinical stage I a-I b lung cancer were treated with cyberknife at Tianjin Cancer Hospital. Of the 11 patients receiving CT guided biopsy, 3 were squamous cell cancer and 8 were adenocarcinoma. Six patients refused intrusive operation and were diagnosed by PET-CT scan. All patients were medically inoperable evaluated by a thoracic surgeon. The PTV=GTV + 3-5 mm, and the median volume of PTV was 36 cm 3 (6-82 cm 3 ). The median total prescription dose was 50 Gy(45-60 Gy) at 3-5 fractions. Results: The median follow-up time was 7 months(3-11 months). All the patients finished the treatment and were alive by the last follow-up. Slight fatigue was the most common complain. Evaluated by CT scan, 13 were complete response and 4 were partial response. No recurrence, progression or distant metastasis occurred. There were 3 patients with grade I granulocytopenia, 3 grade I pneumonitis and 1 grade II pneumonitis. Conclusions: The cyberknife radiosurgery treatment in early stage lung cancer shows a high rate of local control and minimal toxicity. Long time follow-up is necessary to evaluate the survival data and late toxicity. (authors)

A single randomized trial established lobectomy as the standard of care for the surgical treatment of early-stage non-small cell lung cancer. Recent advances in imaging/staging modalities and detection of smaller tumors have once again rekindled interest in sublobar resection for early-stage disease. The objective of this study was to compare lung cancer survival in patients with non-small cell lung cancer with a diameter of 30 mm or less with clinical stage 1 disease who underwent lobectomy or sublobar resection. We identified 347 patients diagnosed with lung cancer who underwent lobectomy (n = 294) or sublobar resection (n = 53) for non-small cell lung cancer manifesting as a solid nodule in the International Early Lung Cancer Action Program from 1993 to 2011. Differences in the distribution of the presurgical covariates between sublobar resection and lobectomy were assessed using unadjusted P values determined by logistic regression analysis. Propensity scoring was performed using the same covariates. Differences in the distribution of the same covariates between sublobar resection and lobectomy were assessed using adjusted P values determined by logistic regression analysis with adjustment for the propensity scores. Lung cancer-specific survival was determined by the Kaplan-Meier method. Cox survival regression analysis was used to compare sublobar resection with lobectomy, adjusted for the propensity scores, surgical, and pathology findings, when adjusted and stratified by propensity quintiles. Among 347 patients, 10-year Kaplan-Meier for 53 patients treated by sublobar resection compared with 294 patients treated by lobectomy was 85% (95% confidence interval, 80-91) versus 86% (confidence interval, 75-96) (P = .86). Cox survival analysis showed no significant difference between sublobar resection and lobectomy when adjusted for propensity scores or when using propensity quintiles (P = .62 and P = .79, respectively).

We investigated the efficacy and safety of S-1 and cisplatin with concurrent thoracic radiation (SCCR) over cisplatin alone plus concurrent thoracic radiation (CCR) for unresectable stage III non-small-cell lung cancer (NSCLC). Between January 2009 and November 2011, 40 eligible patients with NSCLC were included and divided randomly into two groups. Twenty patients received SCCR with S-1 (orally at 40 mg/m 2 per dose, b.i.d.) on days 1 through 14, cisplatin (60 mg/m 2 on day 1) every 4 weeks for two cycles, and radiotherapy (60 Gy/30 fractions over 6 weeks) beginning on day 1. Twenty subjects received CCR (cisplatin and radiotherapy, the same as for SCCR). The 3-year overall response rate was 59.3% and 52.4% for the SCCR and CCR groups, respectively, and the difference was statistically significant, while the median overall survival was 33 months (range, 4–41 months) and 24 months (range, 2–37 months), respectively (P = 0.048). The median progression-free survival was 31 months for SCCR (range, 5–39 months), whereas it was 20 months (range, 2–37 months) for CCR (P = 0.037). The toxicity profile was similar in both groups. In summary, we demonstrated that S-1 and cisplatin with concurrent thoracic radiation was more effective than cisplatin plus radiotherapy in NSCLC patients with acceptable toxicity

Purpose: To study the dosimetric predictors of early clinical toxicity following SBRT in patients with lung tumors and planning target volumes (PTV) exceeding 80 cm 3 . Methods: Eighteen consecutive patients who were treated using volumetric modulated arc therapy (RapidArc TM ) were assessed. All were either unfit or refused to undergo surgery or chemoradiotherapy. PTV planning objectives were as used in the ROSEL study protocol. Clinical toxicity was scored using Common Toxicity Criteria AE4.0. Lung volumes receiving 5, 10, 15, and 20 Gy (V 5 , V 10 , V 15 and V 20 ) and mean lung dose were assessed and correlated to symptomatic radiation pneumonitis (RP). Results: Median age, age-adjusted Charlson-comorbidity score and PTV size were 74, 7.5 and 137 cm 3 , respectively. At a median follow-up of 12.8 months, 8 deaths were recorded: 5 arising from comorbidity, 2 were potentially treatment-related and 1 had local recurrence. RP was reported in 5 patients (grade 2 in 3 and grade 3 in 2). All RP occurred in plans without a high priority optimization objective on contralateral lung. Acute RP was best predicted by contralateral lung V 5 (p 80 cm 3 , the contralateral lung V 5 best predicts RP. Limiting contralateral lung V 5 to <26% may reduce acute toxicity.

The prognosis of patients with non-small cell lung cancer (NSCLC) is important, as patients with resectable disease and poor prognostic variables might benefit from neoadjuvant therapy. The goal of this study is to evaluate SUVmax, SUVmax ratio, CT volume (CTvol), metabolic tumour volume (MTV) and total lesion glycolisis (TLG) as survival prognostic markers. In addition, we defined two variables; MTV x SUVmax (MTVmax) and CTvol x SUVmax (CTvolmax) and assessed whether they can be used as prognostic markers. Patients with stage I-II NSCLC who underwent 18 F FDG PET/CT and surgery were evaluated. Cox proportional-hazard model was used to determine the association between variables and survival. Similar analysis was performed in cases with no lymph node (LN) involvement. One hundred and eighty-one patients were included (at the end of the study, 140 patients were alive). SUVmax with a cut-off value of 8.2 was significant survival prognostic factor regardless of LN involvement (P = 0.012). In cases with no LN involvement, SUVmax and CTvol (≥7.1 ml) were significant survival prognostic factors with P = 0.004 and 0.03, respectively. SUVmax may be a useful prognostic variable in stage I-II NSCLC while morphologic tumour volume might be useful in cases with no lymph node involvement. (orig.)

Podoplanin expression in cancer-associated fibroblasts (CAFs) has been proposed as an unfavourable indicator in squamous cell carcinoma of the lung, but little is known about its clinical significance in early-stage lung adenocarcinoma. We evaluated the prognostic impact of podoplanin expression in patients with pathological stage (p-stage) IA lung adenocarcinoma as categorised by the 8th edition of the tumour-node-metastasis classification for lung cancer. Immunohistochemical analyses using anti-podoplanin antibody were performed on resected specimens from 158 patients with p-stage IA lung adenocarcinoma. When more than 10% of cancer cells or CAFs showed immunoreactivity with podoplanin, the specimens were classified as podoplanin-positive. Podoplanin-positive status in cancer cells (n = 8) was not correlated with clinicopathological factors or with patient prognosis. Podoplanin-positive status in CAFs (n = 41) was correlated significantly with poorer tumour differentiation (P < 0.001), the presence of lymphatic invasion (P < 0.001) and high-grade (solid and/or micropapillary) components constituting ≥1% of the entire tumour (P < 0.001). The log-rank test showed that podoplanin-positive status in CAFs was associated significantly with shorter disease-free survival (DFS) (P < 0.001) and disease-specific survival (P = 0.015). In Cox's multivariate analysis, podoplanin-positive status in CAFs had the most significant effect on shorter DFS [hazard ratio (HR) = 4.411, P = 0.004], followed by the presence of high-grade components (HR = 3.581, P = 0.013). Podoplanin expression in CAFs could be an independent predictor of increased risk of recurrence in patients with p-stage IA lung adenocarcinoma. © 2017 John Wiley & Sons Ltd.

Purpose: To evaluate whether complex radiotherapy (RT) planning was associated with improved outcomes in a cohort of elderly patients with unresected Stage I-II non-small-cell lung cancer (NSCLC). Methods and Materials: Using the Surveillance, Epidemiology, and End Results registry linked to Medicare claims, we identified 1998 patients aged >65 years with histologically confirmed, unresected stage I-II NSCLC. Patients were classified into an intermediate or complex RT planning group using Medicare physician codes. To address potential selection bias, we used propensity score modeling. Survival of patients who received intermediate and complex simulation was compared using Cox regression models adjusting for propensity scores and in a stratified and matched analysis according to propensity scores. Results: Overall, 25% of patients received complex RT planning. Complex RT planning was associated with better overall (hazard ratio 0.84; 95% confidence interval, 0.75-0.95) and lung cancer-specific (hazard ratio 0.81; 95% confidence interval, 0.71-0.93) survival after controlling for propensity scores. Similarly, stratified and matched analyses showed better overall and lung cancer-specific survival of patients treated with complex RT planning. Conclusions: The use of complex RT planning is associated with improved survival among elderly patients with unresected Stage I-II NSCLC. These findings should be validated in prospective randomized controlled trials.

This study presents the results of analysis of 134 lung cancer patients treated with radiotherapy in 1999-2002. The objective of the paper was to evaluate the importance of some prognostic factors on survival of lung cancer patients. We have analyzed influence of patient's age, stage of the disease, tumor size, lymphnodes status, histological type and radiotherapy dose to the survival of lung cancer patients. Among analyzed patients 87% were males and 73.9% were more than 60 years old. Locally advanced lung cancer was diagnosed in 65.6% of cases. The non-small cell lung cancer was diagnosed in 83.8% of cases. During the study period 58.2% of patients died. Statistically significant prognostic factors in our study were: stage, locally advanced lung cancer, involvement of the lymphnodes, III B and IV of the disease. The survival of the patients depends on the radiotherapy dose in our study. The better survival was associated with the bigger than 50 Gy dose (p<0.001). (author)

Clinical and pathological indicators are inadequate for prognosis of stage II and III colorectal carcinoma (CRC). In this study, we utilized the activity of regulatory factors, univariate Cox regression and random forest for variable selection and developed a multivariate Cox model to predict the overall survival of Stage II/III colorectal carcinoma in GSE39582 datasets (469 samples). Patients in low-risk group showed a significant longer overall survival and recurrence-free survival time than those in high-risk group. This finding was further validated in five other independent datasets (GSE14333, GSE17536, GSE17537, GSE33113, and GSE37892). Besides, associations between clinicopathological information and risk score were analyzed. A nomogram including risk score was plotted to facilitate the utilization of risk score. The risk score model is also demonstrated to be effective on predicting both overall and recurrence-free survival of chemotherapy received patients. After performing Gene Set Enrichment Analysis (GSEA) between high and low risk groups, we found that several cell-cell interaction KEGG pathways were identified. Funnel plot results showed that there was no publication bias in these datasets. In summary, by utilizing the regulatory activity in stage II and III colorectal carcinoma, the risk score successfully predicts the survival of 1021 stage II/III CRC patients in six independent datasets.

Anatomical cancer extent is an important predictor of prognosis and determines treatment choices. In non-small-cell lung cancer (NSCLC) the tumour-node-metastasis (TNM) classification developed by Pierre Denoix replaced in 1968 the Veterans Administration Lung cancer Group (VALG) classification, which was still in use for small-cell lung cancer (SCLC). Clifton Mountain suggested several improvements based on a database of mostly surgically treated United States (US) patients from a limited number of centres. This database was pivotal for a uniform reporting of lung cancer extent by the American Joint Committee of Cancer (AJCC) and the International Union against Cancer (IUCC), but it suffered increasingly from obsolete diagnostic and staging procedures and did not reflect new treatment modalities. Moreover, its findings were not externally validated in large Japanese and European databases, resulting in persisting controversies which could not be solved with the available database. The use of different mediastinal lymph-node maps in Japan, the (US) and Europe facilitated neither the exchange nor the comparison of treatment results. Peter Goldstraw, a United Kingdom (UK) thoracic surgeon, started the process of updating the sixth version in 1996 and brought it to a good end 10 years later. His goals were to improve the TNM system in lung cancer by addressing the ongoing controversies, to validate the modifications and additional descriptors, to validate the TNM for use in staging SCLC and carcinoid tumours, to propose a new uniform lymph-node map and to investigate the prognostic value of non-anatomical factors. A staging committee was formed within the International Association for the Study of Lung Cancer (IASLC) - which supervised the collection of the retrospective data from >100,000 patients with lung cancer - treated throughout the world between 1990 and 2000, analyse them with the help of solid statistics and validate externally with the Surveillance

with higher radiotherapy doses and larger treatment volumes. On patterns of failure analysis, 42% of failures were local-only and 38% were distant-only. Regional-only failure occurred in 4 patients (7%), 3 of whom failed solely in an unirradiated nodal site. Analysis of factors correlating with local failure at 2 years was performed using a multinominal logistic regression analysis. Significant factors associated with a lower local failure included incidental diagnosis and absence of cough with a strong trend toward significance for higher radiotherapy dose (p = 0.07) and larger treatment volume (p = 0.08). Patients who were locally controlled had an improved cause-specific survival at 5 years over those who were not controlled (46% vs. 12%, p = 0.03). Grade III-V complications occurred in 2 patients (1.5%). Conclusion: Patients with clinical Stage I medically inoperable non-small-cell lung cancer treated with contemporary radiotherapy alone achieved a 5-year cause-specific survival of 32%. Uncontrolled lung cancer was the primary cause of death in these patients, and local failure alone represented the most common mode of failure (42%). Patients who were locally controlled had a significantly improved cause-specific survival over those who failed locally. Because higher doses of radiotherapy appear to provide improved local control, studies of dose escalation are warranted until dose-limiting toxicity is observed

Full Text Available Claudio Tantucci, Denise ModinaUnit of Respiratory Medicine, Department of Medical and Surgical Sciences, University of Brescia, Brescia, ItalyAbstract: The landmark study of Fletcher and Peto on the natural history of tobacco smoke-related chronic airflow obstruction suggested that decline in the forced expiratory volume in the first second (FEV1 in chronic obstructive pulmonary disease (COPD is slow at the beginning, becoming faster with more advanced disease. The present authors reviewed spirometric data of COPD patients included in the placebo arms of recent clinical trials to assess the lung function decline of each stage, defined according to the severity of airflow obstruction as proposed by the Global Initiative for Chronic Obstructive Lung Disease (GOLD guidelines. In large COPD populations the mean rate of FEV1 decline in GOLD stages II and III is between 47 and 79 mL/year and 56 and 59 mL/year, respectively, and lower than 35 mL/year in GOLD stage IV. Few data on FEV1 decline are available for GOLD stage I. Hence, the loss of lung function, assessed as expiratory airflow reduction, seems more accelerated and therefore more relevant in the initial phases of COPD. To have an impact on the natural history of COPD, it is logical to look at the effects of treatment in the earlier stages.Keywords: chronic obstructive pulmonary disease, decline, forced expiratory volume in 1 second, FEV1

Aim: To determine true-positive and true-negative rates of PET/CT studies in the staging of lung cancer as compared with conventional imaging (CT and bone scan and occasionally MRI) and the impact of PET/CT on the treatment strategy in patients with lung cancer. Materials and method: Twenty patients (21 studies) with known or suspected lung cancer (14 patients with non-small-cell lung cancer (NSCLC), three patients with small-cell lung cancer (SCLC), three patients with solitary pulmonary nodule underwent initial staging (seven studies) or restaging (14 studies) with combined FDG PET and CT scans on a PET/CT tomograph. PET/CT images were evaluated separately by two nuclear medicine physicians and two radiologists specialized on PET, CT, and MRI. Histology results and a more than 6 months follow-up served as the reference standards. Results: Accurate diagnosis was achieved on 16 studies. Site-by-site analysis gave the following results: 16 true-positive sites (seven on histology, nine on >6 months follow-up), six true-negative sites (two on histology, four on >6 months follow-up). On PET/CT, six patients were correctly down-staged, three patients were correctly upstaged and seven patients were diagnosed correctly as being on the same stage (2/7 with increase of extent of disease, 5/7 with the same extent of disease). One patient was falsely upstaged and three patients were falsely down-staged. On the basis of PET/CT results, change of management was induced in six patients, while in 14 patients there was no change induced. In five cases PET/CT was partially accurate: on site-by-site analysis, four sites proved true positive (on histology), one site false positive (on histology), and four sites false negative (one on histology, three on >6 months follow-up). Conclusion: In our early experience, PET/CT contributed significantly to correct staging and management of patients with lung cancer.

Mai Yamauchi

Full Text Available PURPOSE: To identify stage I lung adenocarcinoma patients with a poor prognosis who will benefit from adjuvant therapy. PATIENTS AND METHODS: Whole gene expression profiles were obtained at 19 time points over a 48-hour time course from human primary lung epithelial cells that were stimulated with epidermal growth factor (EGF in the presence or absence of a clinically used EGF receptor tyrosine kinase (RTK-specific inhibitor, gefitinib. The data were subjected to a mathematical simulation using the State Space Model (SSM. "Gefitinib-sensitive" genes, the expressional dynamics of which were altered by addition of gefitinib, were identified. A risk scoring model was constructed to classify high- or low-risk patients based on expression signatures of 139 gefitinib-sensitive genes in lung cancer using a training data set of 253 lung adenocarcinomas of North American cohort. The predictive ability of the risk scoring model was examined in independent cohorts of surgical specimens of lung cancer. RESULTS: The risk scoring model enabled the identification of high-risk stage IA and IB cases in another North American cohort for overall survival (OS with a hazard ratio (HR of 7.16 (P = 0.029 and 3.26 (P = 0.0072, respectively. It also enabled the identification of high-risk stage I cases without bronchioalveolar carcinoma (BAC histology in a Japanese cohort for OS and recurrence-free survival (RFS with HRs of 8.79 (P = 0.001 and 3.72 (P = 0.0049, respectively. CONCLUSION: The set of 139 gefitinib-sensitive genes includes many genes known to be involved in biological aspects of cancer phenotypes, but not known to be involved in EGF signaling. The present result strongly re-emphasizes that EGF signaling status in cancer cells underlies an aggressive phenotype of cancer cells, which is useful for the selection of early-stage lung adenocarcinoma patients with a poor prognosis.

Lung cancer is the most common cancer in the world. Despite this, there have been few cases of simultaneous primary and metastatic cancers in the lung reported, let alone coexisting with tumor-to-tumor metastasis. Herein, we describe an extremely unusual case. A 61-year-old man with a history of colon adenocarcinoma was revealed as having three nodules in the lung 11 months after colectomy. The nodule in the left upper lobe was primary lung adenocarcinoma, the larger one in the right upper lobe was a metastasis of colon adenocarcinoma, and the smaller one in the right upper lobe was colon adenocarcinoma metastasizing to lung adenocarcinoma. Our paper focused on the differential diagnosis and cancer staging of this unique case, and discussed the uncommon phenomenon of the lung acting as a recipient in tumor-to-tumor metastasis.

Immune and Inflammatory Cell Composition of Human Lung Cancer Stroma.

Directory of Open Access Journals (Sweden)

G-Andre Banat

Full Text Available Recent studies indicate that the abnormal microenvironment of tumors may play a critical role in carcinogenesis, including lung cancer. We comprehensively assessed the number of stromal cells, especially immune/inflammatory cells, in lung cancer and evaluated their infiltration in cancers of different stages, types and metastatic characteristics potential. Immunohistochemical analysis of lung cancer tissue arrays containing normal and lung cancer sections was performed. This analysis was combined with cyto-/histomorphological assessment and quantification of cells to classify/subclassify tumors accurately and to perform a high throughput analysis of stromal cell composition in different types of lung cancer. In human lung cancer sections we observed a significant elevation/infiltration of total-T lymphocytes (CD3+, cytotoxic-T cells (CD8+, T-helper cells (CD4+, B cells (CD20+, macrophages (CD68+, mast cells (CD117+, mononuclear cells (CD11c+, plasma cells, activated-T cells (MUM1+, B cells, myeloid cells (PD1+ and neutrophilic granulocytes (myeloperoxidase+ compared with healthy donor specimens. We observed all of these immune cell markers in different types of lung cancers including squamous cell carcinoma, adenocarcinoma, adenosquamous cell carcinoma, small cell carcinoma, papillary adenocarcinoma, metastatic adenocarcinoma, and bronchioloalveolar carcinoma. The numbers of all tumor-associated immune cells (except MUM1+ cells in stage III cancer specimens was significantly greater than those in stage I samples. We observed substantial stage-dependent immune cell infiltration in human lung tumors suggesting that the tumor microenvironment plays a critical role during lung carcinogenesis. Strategies for therapeutic interference with lung cancer microenvironment should consider the complexity of its immune cell composition.

The aim of this study was to provide insight in the use, intensity and toxicity of therapy with capecitabine and oxaliplatin (CAPOX) and capecitabine monotherapy (CapMono) among elderly stage III colon cancer patients treated in everyday clinical practice. Data from the Netherlands Cancer Registry were used. All stage III colon cancer patients aged ≥70 years diagnosed in the southeastern part between 2005 and 2012 and treated with CAPOX or CapMono were included. Differences in completion of all planned cycles, cumulative dosages and toxicity between both regimens were evaluated. One hundred ninety-three patients received CAPOX and 164 patients received CapMono; 33% (n = 63) of the patients receiving CAPOX completed all planned cycles of both agents, whereas 55% (n = 90) of the patients receiving CapMono completed all planned cycles (P characteristics, CapMono was associated with a lower odds of developing grade III-V toxicity than CAPOX (odds ratio 0.54, 95% confidence interval 0.33-0.89). For patients treated with CAPOX, the most common toxicities were gastrointestinal (29%), haematological (14%), neurological (11%) and other toxicity (13%). For patients treated with CapMono, dermatological (17%), gastrointestinal (13%) and other toxicity (11%) were the most common. CAPOX is associated with significantly more grade III-V toxicities than CapMono, which had a pronounced impact on the cumulative dosage received and completion of all planned cycles. In this light, CapMono seems preferable over CAPOX. Copyright © 2016 Elsevier Ltd. All rights reserved.

Radiofrequency Ablation for Early-Stage Nonsmall Cell Lung Cancer

Directory of Open Access Journals (Sweden)

Full Text Available This review examines studies of radiofrequency ablation (RFA of nonsmall cell lung cancer (NSCLC and discusses the role of RFA in treatment of early-stage NSCLC. RFA is usually performed under local anesthesia with computed tomography guidance. RFA-associated mortality, while being rare, can result from pulmonary events. RFA causes pneumothorax in up to 63% of cases, although pneumothorax requiring chest drainage occurs in less than 15% of procedures. Other severe complications are rare. After RFA of stage I NSCLC, 31–42% of patients show local progression. The 1-, 2-, 3-, and 5-year overall survival rates after RFA of stage I NSCLC were 78% to 100%, 53% to 86%, 36% to 88%, and 25% to 61%, respectively. The median survival time ranged from 29 to 67 months. The 1-, 2-, and 3-year cancer-specific survival rates after RFA of stage I NSCLC were 89% to 100%, 92% to 93%, and 59% to 88%, respectively. RFA has a higher local failure rate than sublobar resection and stereotactic body radiation therapy (SBRT. Therefore, RFA may currently be reserved for early-stage NSCLC patients who are unfit for sublobar resection or SBRT. Various technologies are being developed to improve clinical outcomes of RFA for early-stage NSCLC.

Practice guidelines have been developed for early-stage and locally advanced non-small cell lung cancer (NSCLC). However, many common clinical scenarios still require individualized decision making. This is true for locoregional relapse after initial stereotactic radiotherapy (stereotactic body radiation therapy or stereotactic ablative radiotherapy; SBRT or SABR), an increasingly utilized curative treatment option for stage I NSCLC. A consortium of expert radiation oncologists was established with the aim of providing treatment recommendations. In this scenario, a case was distributed to six radiation oncologists who provided their institutions' treatment recommendations. In this case, a patient developed local and mediastinal relapse after SABR (45 Gy, 3 fractions), comparable to the tumor burden in de novo stage IIIA NSCLC. Treatment recommendations were tabulated and a consensus conclusion was developed. Three institutions recommended evaluation for surgery. If the patient was not a surgical candidate, and/or refused surgery, definitive chemoradiation was recommended, including retreating the primary to full dose. European participants were more in favor of a non-surgical approach. None of the participants were reluctant to prescribe reirradiation, but two institutions prescribed doses lower than 60 Gy. Platinum-based doublets together with intensity-modulated radiotherapy were preferred. The institutional recommendations reflect the questions and uncertainties discussed in current stage III guidelines. All institutions agreed that previous SABR is not a contraindication for salvage chemoradiation. In the absence of high-quality prospective trials for recurrent NSCLC, all treatment options recommended in current guidelines for stage III disease can be considered in clinical scenarios such as this.

Purpose CT has been found superior to chest x-ray to detect lung malignances. However, indeterminate lung lesions (ILL) are found in 4-42% by using CT in staging colorectal cancer (CRC) patients. Our aim was to examine the frequency of ILL on staging CT and the rate of the ILL being malignant...... CT performed 6, 12, 18 and 24 months postoperatively. Results Twenty percent of the patients had ILL. Four of these patients (8.5%) had lung metastases detected median 9 months postoperatively, while 2 (4.3%) had other lung malignancies. One patient had TB. In patients with normal staging chest CT 10...... of the 185 patients (5.4%) developed lung metastases detected median 16 months postoperatively. This was significantly later than in patients with ILL (p lung metastases no significant difference was found between the groups (p = 0...

To evaluate the accuracy of systematic mediastinal staging by endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) (sampling of all visible nodes measuring ≥5mm from stations N3 to N1 regardless of their positron emission tomography/computed tomography (PET/CT) features) and compare this staging approach with targeted EBUS-TBNA staging (sampling only 18F-fluorodeoxyglucose (FDG)-avid nodes) in patients with N2 non-small cell lung cancer (NSCLC) on PET/CT. Retrospective study of 107 patients who underwent systematic EBUS-TBNA mediastinal staging. The results were compared with those of a hypothetical scenario where only FDG-avid nodes on PET/CT would be sampled. Systematic EBUS-TBNA sampling demonstrated N3 disease in 3 patients, N2 disease in 60 (42 single-station or N2a, 18 multiple-station or N2b) and N0/N1 disease in 44. Of these 44, seven underwent mediastinoscopy, which did not show mediastinal disease; six of the seven proceeded to lung resection, which also showed no mediastinal disease. Thirty-four N0/N1 patients after EBUS-TBNA underwent lung resection directly: N0/N1 was found in 30 and N2 in four (one N2b with a PET/CT showing N2a disease, three N2a). Sensitivity, specificity, negative predictive value, positive predictive value, and overall accuracy of systematic EBUS-TBNA were 94%, 100%, 90%, 100% and 96%, respectively. Compared to targeted EBUS-TBNA, systematic EBUS-TBNA sampling provided additional important clinical information in 14 cases (13%): three N3 cases would have passed unnoticed, and 11 N2b cases would have been staged as N2a. In clinical practice, systematic sampling of the mediastinum by EBUS-TBNA, regardless of PET/CT features, is to be recommended over targeted sampling. Copyright © 2018. Published by Elsevier Inc.

The use of positron emission tomography compared with conventional staging increases the detection of extrathoracic metastases and reduces the number futile thoracotomies in patients being evaluated for surgical resection. Long-term follow-up of one of the two adjuvant chemotherapy trials revealed a continued overall survival (OS) benefit to adjuvant chemotherapy. In locally advanced non-small cell lung cancer, a phase III trial of chemoradiotherapy alone and with surgical resection revealed no statistically significant difference in OS between the treatment arms. In advanced stage non-small cell lung cancer, a phase III trial compared gefitinib with carboplatin and paclitaxel in a clinically enriched patient population for epidermal growth factor receptor (EGFR) tyrosine kinase (TK) mutations; among patients with an EGFR TK mutation, patients in gefitinib arm compared with carboplatin and paclitaxel arm experienced a statistically significant superior response rate and progression-free survival, and among patients without EGFR TK mutation patients in the gefitinib arm compared with carboplatin and paclitaxel experienced a statistically significant inferior response rate and progression-free survival. A phase III trial of platinum-based therapy with and without cetuximab in the first-line setting revealed improved OS in the cetuximab arm. A phase III trial of maintenance pemetrexed compared with placebo in patients who had not progressed after initial platinum-based therapy revealed an improvement in OS of patients in the pemetrexed arm with nonsquamous histology. In limited-stage small cell lung cancer, a phase III trial compared standard and high-dose prophylactic cranial irradiation and revealed no significant difference in the rate of brain metastases between the two treatment arms.

Purpose: This study was performed to assess the smoking habits and changes in the cigarette smoking habits of patients prior to, at the time of and after the diagnosis of unresectable stage IIIA/IIIB non-small cell lung cancer. Methods: Patients with the diagnosis of unresectable stage IIIA/IIIB non-small cell lung cancer who had agreed to enter a phase III North Central Cancer Treatment Group Trial comparing twice daily thoracic radiation therapy (TRT) given with chemotherapy to once daily TRT given with chemotherapy were asked to fill out a questionnaire regarding their past and present cigarette smoking habits. This questionnaire included information regarding the number of years of smoking, number of packs of cigarettes smoked per day and the time frame of smoking history. Subsequently, patients were given questionnaires to assess changes in smoking history at the halfway point of treatment, and during follow-up visits. Results: Of the 140 patients who were entered on the above noted trial, 132 filled out baseline questionnaires and were the subject of this study. Of these 132 patients, 126 (95%) had either smoked cigarettes in the past or smoked at the time of study entry. The median pack years of smoking. (years of smoking x packs per day) was 43 with a range of 3-169 pack years. Of the 126 patients with a smoking history, 124 provided information regarding the status of their smoking at the time of entry on the study: 89 (72%) claimed to have quit smoking and, 35 (28%) reported that they continued to smoke an average of one pack per day. Of the 89 patients who had quit smoking, roughly one third had quit within the month before study entry and 45% had quit during the 8 month period prior to entry on the study. Of the 35 patients who continued to smoke at the time of entry on the study, 21 indicated that they stopped smoking during the period following randomization. Hence 10% of the original 140 patients entered on study continued to smoke an average of one

Aim: To determine the role of 2-[(18)F] fluoro-2- deoxy-D-glucose (FDG) positron emission tomography (PET) in morphometric tumor response after neoadjuvant chemoradiation, findings in 32 patients were analyzed prospectively in an ongoing multicenter trial (LUCAS-MD, Germany). Material and Methods: Inclusion criteria was histologically confirmed NSCLC stage IIIA/IIIB. For staging all patients received a PET scan in addition to a spiral CT and/or MRI before therapy. Neoadjuvant treatment consisted of 2-3 cycles of chemotherapy with paclitaxel (225 mg/m 2 ) and carboplatin (AUC 6), each d1 q22 and a block of chemoradiation (45Gy, 1.5Gy b.i.d., concomitant with paclitaxel (50 mg/m 2 ) and carboplatin (AUC = 2), each d1, d8, d15) followed by surgery. All patients received a second PET after completion of neoadjuvant therapy prior to surgery. Whole-body PET (ECAT Exact 47) studies (attenuation corrected, iteratively reconstructed) were obtained 60 min. after injection of 6 MBq/kg body weight F-18 FDG. For semi-quantitative analysis, the tumor standardized uptake values (SUV), the tumor to background SUV ratio (T/B ratio), the metabolic tumor diameter (MTD) and the metabolic tumor index (MTI = SUV x MTD) were assessed in all primary tumors and in metastatic lymph nodes. Additionally, image fusion of PET with CT data was applied (using a HERMES Computer, Nuclear Diagnostics, Sweden). Results: So far, all patients (7/32) with complete metabolic response in lymph node metastases detected by PET, had no vital tumor cells (morphometric regression grade III). In primary tumors showing complete metabolic response, the regression grade was IIB (less than 10% vital tumor cells) or III. Conclusion: Morphometric tumor response after neoadjuvant therapy correlates strongly with metabolic remission by FDG-PET. PET precedes the tumor response as measured by CT after neoadjuvant treatment and may predict the long term therapeutic outcome in stage III NSCLC

To evaluate the treatment results in early stage non-small cell lung cancer patients who have undergone fiducial-less CyberKnife radiosurgery (CKRS). From June 2011 to November 2013, 58 patients underwent CKRS at Asan Medical Center for stage I lung cancer. After excluding 14 patients, we retrospectively reviewed the records of the remaining 44 patients. All analyses were performed using SPSS ver. 21. The median age at diagnosis was 75 years. Most patients had inoperable primary lung cancer with a poor pulmonary function test with comorbidity or old age. The clinical stage was IA in 30 patients (68.2%), IB in 14 (31.8%). The mean tumor size was 2.6 cm (range, 1.2 to 4.8 cm), and the tumor was smaller than 2 cm in 12 patients (27.3%). The radiation dose given was 48-60 Gy in 3-4 fractions. In a median follow-up of 23.1 months, local recurrence occurred in three patients (2-year local recurrence-free survival rate, 90.4%) and distant metastasis occurred in 13 patients. All patients tolerated the radiosurgery well, only two patients developing grade 3 dyspnea. The most common complications were radiation-induced fibrosis and pneumonitis. Eight patients died due to cancer progression. The results showed that fiducial-less CKRS shows comparable local tumor control and survival rates to those of LINAC-based SABR or CKRS with a fiducial marker. Thus, fiducial-less CKRS using Xsight lung tracking system can be effectively and safely performed for patients with medically inoperable stage I non-small cell lung cancer without any risk of procedure-related complication

Purpose: Results of radical radiotherapy in the treatment of inoperable NSCLC can be improved by either concurrent daily low-dose Cisplatin as radiosensitizer (Shaake-Koning, N Engl J Med, 1992; 326: 524) or by using neoadiuvant chemotherapy (Dillman, N Engl J Med, 1990; 323: 940). The aim of present study was to evaluate the activity and feasibility of a new chemo-radiotherapy (CT-RT) regimen in which both strategies of RT improvement will be used. Methods: Thirty consecutive patients (pts) were treated with induction CT (Cisplatin 100 mg/m{sup 2} i.v. day 1,22 + Vinblastine 5 mg/m{sup 2} i.v. day 1,8,15,22,29) followed by RT (60 Gy/30 fractions in 6 wks) combined with Cisplatin 5 mg/m{sup 2} daily before RT. Patients' characteristics were: 29 pts were male and 1 female; median age 60.5 yrs (range 44-69); median PS 1 (range 0-1); 21 squamous cell carcinoma and 9 adenocarcinoma; stage III A in 9 pts and stage IIIB in 21 pts. Results: Twenty-three pts were evaluable for RT plus daily Cisplatin toxicity and 29 for CT toxicity (according to WHO). For RT plus daily cisplatin hematological toxicity consisted of grade III leukopenia in 22%, grade III anemia 9% and grade III thrombocytopenia in 9% of pts. Only 2 patients developed severe esophagitis. Only one case of radiation pneumonitis was reported. For induction CT hematological toxicity consisted of grade III-IV leukopenia in 31%, grade II anemia 10% and grade IV thrombocitopenia in 14% of cases. Non-hematological toxicity consisted mainly of grade I peripheral neuropaty and occured in 17% of pts. One case of minor hearing loss and 4 cases of tinnitus were observed at the end of treatment. Twenty-seven pts were evaluable for response. Response rate was 59% with 7 CRs (26%) and 9 PRs (33%); 1 patient had SD (4%), 5 pts PD (20%) and 5 pts (19%) died early (3 for early progression, 1 for toxicity and 1 for cardiac failure). All pts with CR are still alive with a median event-free survival of 23.9 months (range 12

2013-01-01

Background: Stage IV non-small cell lung cancer (NSCLC) is a treatable, but not curable, clinical entity in patients given the diagnosis at a time when their performance status (PS) remains good. Methods: A systematic literature review was performed to update the previous edition of the American College of Chest Physicians Lung Cancer Guidelines. Results: The use of pemetrexed should be restricted to patients with nonsquamous histology. Similarly, bevacizumab in combination with chemotherapy (and as continuation maintenance) should be restricted to patients with nonsquamous histology and an Eastern Cooperative Oncology Group (ECOG) PS of 0 to 1; however, the data now suggest it is safe to use in those patients with treated and controlled brain metastases. Data at this time are insufficient regarding the safety of bevacizumab in patients receiving therapeutic anticoagulation who have an ECOG PS of 2. The role of cetuximab added to chemotherapy remains uncertain and its routine use cannot be recommended. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors as first-line therapy are the recommended treatment of those patients identified as having an EGFR mutation. The use of maintenance therapy with either pemetrexed or erlotinib should be considered after four cycles of first-line therapy in those patients without evidence of disease progression. The use of second- and third-line therapy in stage IV NSCLC is recommended in those patients retaining a good PS; however, the benefit of therapy beyond the third-line setting has not been demonstrated. In the elderly and in patients with a poor PS, the use of two-drug, platinum-based regimens is preferred. Palliative care should be initiated early in the course of therapy for stage IV NSCLC. Conclusions: Significant advances continue to be made, and the treatment of stage IV NSCLC has become nuanced and specific for particular histologic subtypes and clinical patient characteristics and according to the

Lung-derived growth factors: possible paracrine effectors of fetal lung development

International Nuclear Information System (INIS)

Montes, A.M.

1985-01-01

A potential role for paracrine secretions in lung organogenesis has been hypothesized (Alescio and Piperno, 1957). These studies present direct support for the paracrine model by demonstrating the presence of locally produced mitogenic/maturational factors in fetal rat lung tissue. Conditioned serum free medium (CSFM) from nineteen-day fetal rat lung cultures was shown to contain several bioactive peptides as detected by 3 H-Thymidine incorporation into chick embryo and rat lung fibroblasts, as well as 14 C-choline incorporation into surfactant in mixed cell cultures. Using ion-exchange chromatography and Sephadex gel filtration, a partially purified mitogen, 11-III, was obtained. The partially purified 11-III stimulates mitosis in chick embryo fibroblasts and post-natal rat lung fibroblasts. Multiplication in fetal rat lung fibroblasts cultures is stimulated only when these are pre-incubated with a competence factor or unprocessed CSFM. This suggests the existence of an endogenously produced competence factor important in the regulation of fetal lung growth. Preparation 11-III does not possess surfactant stimulating activity as assessed by 3 H-choline incorporation into lipids in predominantly type-II cell cultures. These data demonstrate the presence of a maturational/mitogenic factor, influencing type-II mixed cell cultures. In addition, 11-III had been shown to play an autocrine role stimulating the proliferation of fetal lung fibroblasts. Finally, these data suggest the existence of a local produced competence factor

An experimental two-stage rat model of lung carcinoma initiated by radon exposure

We present the results of a two-stage biological model of lung carcinogenesis in rats. The histogenesis of these tumors was examined, and DNA content of lung cells was measured by flow cytometry during the evolving neoplastic stage. Tumors were induced in rat lungs after radon inhalation (1600 WLM) followed by a promoter treatment; six intramuscular injections of 5,6-benzoflavone (25 mg/kg of body weight/injection) every 2 wk. Less than 3 mo after the first injection of benzoflavone, squamous cell carcinoma was observed in the lungs of all rats exposed to radon. The preneoplastic lesions gradually developed as follows: hyperplastic bronchiolar-type cells migrated to the alveoli from cells that proliferated in bronchioles and alveolar ducts; initial lesions were observed in almost all respiratory bronchioles. From some hyperplasias, epidermoid metaplasias arose distally, forming nodular epidermoid lesions in alveoli, which progressed to form squamous papilloma and, finally, epidermoid carcinomas. The histogenesis of these experimentally induced epidermoid carcinomas showed the bronchioloalveolar origin of the tumor. This factor must be considered when comparing these with human lesions; in humans, lung epidermoid carcinomas are thought to arise mainly in the first bronchial generations. The labeling index of pulmonary tissue after incorporation of 3 H-thymidine by the cells was 0.2% in control rats. This index reached a value of 1 to 2% in the hyperplastic area of the bronchioles and 10 to 15% in epidermoid nodules and epidermoid tumors, respectively. DNA cytometric analysis was performed on cell suspensions obtained after enzymatic treatment of paraffin sections of lungs from rats sacrificed during different stags of neoplastic transformations. Data showed the early appearance of a triploid cell population that grew during the evolution of nodular epidermoid lesions to epidermoid carcinomas

Purpose: To evaluate the role of definitive radiation therapy (RT) in the treatment for medically inoperable patients with stage I-II non-small cell lung cancer (NSCLC). Materials and Methods: From 1976 through 1989, 84 patients with clinical stage I and II NSCLC were treated with definitive RT alone at Gunma University hospital. All patients were treated with 10 MV X-rays using antero-posterior parallel opposed fields. The total dose ranged from 60 Gy to 90 Gy (35 pts; 60-69 Gy, 39 pts; 70-74 Gy, 10 pts; ≥ 80 Gy) with once-daily standard fractionation. Results: The two and five-year survival rates were 74% and 31% for 28 patients with stage I disease, as compared with 40% and 19% for 56 patients with stage II respectively (p<0.05). Although there was no significant difference of survival rates by the histologic subtypes, in the patients with squamous cell carcinoma there were more long-term survivors. Fifty-three patients with tumors less than 5 cm in diameter had an infield progression rate of 14% at two years, in comparison with 38% of 31 patients with tumors greater than 5 cm (p<0.05). Overall distant failure occurred in 57% of the patients with smaller tumors and in 80% of the patients with larger tumors (p<0.05). The difference of survival rates for these two groups was statistically significant (p<0.005). Ten patients given a total dose of 80Gy or over had only 17% local progression at the time of last follow-up, however they had not been alive beyond three years because they developed pulmonary insufficiency due to severe stenosis of the proximal bronchus. For age and sex, there were no significant differences in survival, however, patients with performance status of 0-1 lived longer than those with a status of 2 or more (MST 24 versus 13 months; p=0.06). Conclusion: The tumor size was the most important factor not only for local control but also for distant failure. It was also suggested that the optimal radiation dose for medically inoperable stage I-II

Purpose : The aim of this study is to analyze the survival rate, treatment failure and complication of radiation therapy alone in stage III uterine cervical cancer. Materials and Methods : From January 1980 through December 1985, 227 patients with stage II uterine cervical cancer treated with radiation therapy at Kosin Medical Center were retrospectively studied. Among 227 patients, 72 patients(31.7%) were stage IIIa, and 155 patients(68.3%) were stage IIIb according to FIGO classification. Age distribution was 32-71 years(median: 62 years). Sixty nine patients(95.8%) in stage IIIa and 150 patients(96.8%) in stage IIIb were squamous cell carcinoma. Pelvic lymph node metastasis at initial diagnosis was 8 patients (11.1%) in stage IIIa and 29 patients(18.7%) in stage IIIb. Among 72 patients with stage IIIa, 36 patients(50%) were treated with external radiation therapy alone by conventional technique (180-200 cGy/fr). And 36 patients(50%) were treated with external radiation therapy with intracavitary radiotherapy(ICR) with Cs137 sources, and among 155 patients with stage IIIb, 80 patients(51.6%) were treated with external radiation therapy alone and 75 patients(48.4%) were treated with external radiation therapy with ICR. Total radiation doses of stage IIIa and IIIb were 65-105 Gy(median : 78.5 Gy) and 65-125.5 Gy (median :83.5 Gy). Survival rate was calculated by life-table method. Results : Complete response rates were 58.3% (42 patients) in state IIIa and 56.1%(87 patients) in stage Iiib. Overall 5 year survival rates were 57% in stage IIIa and 40% in stage IIIb. Five year survival rates by radiation technique in stage IIIa and IIIb were 64%, 40% in group treated in combination of external radiation and ICR, and 50%, 40% in the group of external radiation therapy alone(P=NS). Five year survival rates by response of radiation therapy in stage IIIa and IIIb were 90%, 66% in responder group, and 10%, 7% in non-responder group (P<0.01). There were statistically no

The aim of this study was to assess the characteristic clinical features of lung cancer associated with pulmonary tuberculosis. Among 1,028 patients with pulmonary tuberculosis admitted in our hospital between 1985 and 2005, 17 (15 men, 2 women; mean age 73±8) were diagnosed as having lung cancer. Patient characteristics, clinical features, radiographic images, treatment and prognosis were evaluated retrospectively. Patients were classified into 2 groups: group A (n=5), lung cancer complicated by active tuberculosis, and group B (n=12), lung cancer with tuberculosis sequelae. All patients in group A and 8 patients (33%) in group B had either stage III or IV lung cancer, whereas 4 patients in group B had stage I lung cancer. Coexistence of lung cancer and pulmonary tuberculosis in the same segment or lobe was seen in 80% (n=4) or 60% (n=3) of group A cases, respectively, and in 67% (n=8) or 8% (n=1) respectively, in group B. Mean survival in group A and group B was 9.2 months and 26.8 months, respectively. More attention should be paid to the possibility of development of lung cancer in individuals with a history of pulmonary tuberculosis or who have had tuberculosis sequelae revealed by chest radiography. Also, the possible coexistence of lung cancer must be carefully examined in patients with active pulmonary tuberculosis. (author)

Full text: FDG-PET has an established role in the management of lung cancer, while the experience with FDG-Co-PET is limited. Our study aims to demonstrate the feasibility of Co-PET in staging and management of lung cancer. Thirty-nine Co-PET studies were performed on our first 36 patients (pts) with primary lung cancer between November 1997 and October 1998. Tomography of brain and torso with an ADAC Solus MCD gamma camera was performed (60 min after 200 MBq of 18 FFDG and > 6 h fasting). Histology subgroups included squamous (14 pts), small cell (1), adeno-carcinoma (11), broncho-alveolar (1), large cell (8), carcinoid (1). CT/clinical staging subgroups included 18 pts in stage 1, 4 in stage 2, 7 in stage 3a, 2 in stage 3b, 8 in stage 4. Compared with CT/clinical staging, FDG upstaged 5 pts (14%) with regional nodal metastases (mets) and 8 pts (22%) with distant mets (cervical = 2, lung = 1, brain = 3, bone = 3, abdomen = 4). FDG under-staged 2 pts in 3 sites (all < 15 mm). Surgical nodal staging was performed in 14 pts: false-positives occurred in 3 CT and 1 Co-PET studies, and false-negatives in one CT/Co-PET. Site sensitivities for primary (smallest 7 mm) and regional lymph nodes are 100% and 88% respectively. Specificities for primary and regional nodes are 100% and 96% respectively. Co-PET also has impact on management: treatment intent (6 pts), radiotherapy fields (1), diagnosis of lung mets (2) and radiation pneumonitis (1). In conclusion, our initial data demonstrate FDG-Co-PET scanning could provide a valuable addition to conventional imaging studies in diagnosis, staging and management of lung cancer

Full text: Positron emission tomography (PET) using F-18 fluorodeoxyglucose (FDG), as a metabolic tumour marker, has been proposed for staging of oncological disease. To determine its role in the mediastinal staging of lung cancer, a prospective comparison of FDG PET with surgery was performed in patients with suspected non-small cell lung carcinoma. The analysis group consists of 70 patients, 49 men and 21 women, mean age 64 yrs (range 41-83 yrs). The PET study was acquired on a Siemens 951/31R scanner over 3 bed positions, 45 minutes following 400MBq FDG. The emission scan was attenuation corrected using measured transmission data. The FDG PET were interpreted by a nuclear physician blinded to the clinical data and the results of the patients' CT scan. On PET, nodes were graded qualitatively on a 5 point scale with scores 4 or greater, positive for tumour involvement. Surgical specimens were obtained in all patients by thoracotomy or mediastinoscopy. The PET metabolic studies and pathology were mapped according to the American Thoracic Society nodal classification resulting in a total of 277 nodal stations evaluated. The PET studies analysed N2 or N3 tumour involvement by nodal station in comparison to histology of pathological specimens or direct visual assessment of the nodal stations at surgery. All patients had proven non-small cell lung carcinoma, except two, in whom, a tissue confirmation of the suspected diagnosis was not attained. PET excluded tumour in 237 of 246 nodal stations (specificity 96%). PET correctly identified 23 of 31 nodal stations with disease (sensitivity 74%). PET correctly staged 260 of 277 nodal stations (accuracy 94%) for disease. FDG PET is an accurate non-invasive functional imaging modality for the mediastinal staging of non-small cell lung cancer and has an important clinical role in the preoperative staging of lung cancer patients

The benefit of adjuvant chemotherapy remains controversial for patients with stage IB non-small-cell lung cancer (NSCLC). This study investigated the effect of adjuvant chemotherapy and the predictors of benefit from adjuvant chemotherapy in patients with stage IB lung adenocarcinoma. A total of 243 patients with completely resected pathologic stage IB lung adenocarcinoma were included in the study. Predictors of the benefits of improved overall survival (OS) or probability of freedom from recurrence (FFR) from platinum-based adjuvant chemotherapy in patients with resected stage IB lung adenocarcinoma were investigated. Among the 243 patients, 70 (28.8%) had received platinum-based doublet adjuvant chemotherapy. A micropapillary/solid-predominant pattern (versus an acinar/papillary-predominant pattern) was a significantly worse prognostic factor for probability of FFR (p = 0.033). Although adjuvant chemotherapy (versus surgical intervention alone) was not a significant prognostic factor for OS (p = 0.303), it was a significant prognostic factor for a better probability of FFR (p = 0.029) on multivariate analysis. In propensity-score-matched pairs, there was no significant difference in OS between patients who received adjuvant chemotherapy and those who did not (p = 0.386). Patients who received adjuvant chemotherapy had a significantly better probability of FFR than those who did not (p = 0.043). For patients with a predominantly micropapillary/solid pattern, adjuvant chemotherapy (p = 0.033) was a significant prognostic factor for a better probability of FFR on multivariate analysis. Adjuvant chemotherapy is a favorable prognostic factor for the probability of FFR in patients with stage IB lung adenocarcinoma, particularly in those with a micropapillary/solid-predominant pattern.

This study was to investigate the differential mitochondrial protein expressions in human lung adenocarcinoma and provide preliminary data for further exploration of the carcinogenic mechanism. Total proteins of A549 and 16HBE mitochondria were extracted through 2D polyacrylamide gel electrophoresis (2-DE). The differential mitochondria proteins were identified by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and were further confirmed by Western blot, immunoelectron microscopy and immunohistochemistry (IHC) in A549 cells as well as lung adenocarcinoma tissues. A total of 41 differentially expressed protein spots were found in A549 mitochondria. Of them, 15 proteins were highly expressed and 26 proteins were lowly expressed in the mitochondria of A549 (by more than 1.5 times). Among the 15 more highly expressed proteins, AAA-TOB3 (by more than 3 times) was highly expressed in the mitochondria of A549 compared with the 16HBE, by LC-MS/MS identification. High electron density and clear circular colloidal gold-marked AAA-TOB3 particles were observed in the A549 cells via immunoelectron microscopy. Besides, AAA-TOB3 was confirmed to be elevated in lung adenocarcinoma by Western blot and IHC. Moreover, increased AAA-TOB3 correlated with lymph node metastasis and advanced stage of lung adenocarcinoma (pAAA-TOB3 was highly expressed in lung adenocarcinoma, and the up-regulation of AAA-TOB3 correlated with lymph node metastasis and advanced stage of lung adenocarcinoma, which suggested that it could serve as a potential molecular marker for lung adenocarcinoma.

Purpose/Objective: The objective of this trial was to test the feasibility of taxol containing combination chemotherapy and concurrent radiation as preoperative or definitive treatment for stage III non small cell lung cancer patients. Methods and Materials: Thirty-three patients were treated on this trial. The initial regimen was (Group 1 pts.): paraplatin (P) (AUC of 4) on day 2, etoposide (E) 50 mg po days 1-5 and 8-12, cisplatin (C) 50 mg/m2 on day 21 and taxol (T) 35 mg/m2 escalated to 45 mg/m2 on days 1 and 8, 24 hr. infusion. After treatment of 10 pts., the regimen was modified as follows (Group 2 pts.): P (AUC of 4) on day 1, E 40 mg/m2 IV daily and days 2-5, and T 80 mg/m2 escalated to 120 mg/m2 on day 1, 3 hr. infusion. After the next 16 pts., the regimen was modified again as follows (Group 3 pts.): P (AUC of 4) on day 1 and T 120 mg/m2 escalated to 140 mg/m2 on day 1, 3 hr. infusion. Seven patients were treated on the latest version of the regimen for a total of 33 pts. The radiation given was uniform throughout the 3 groups. A dose of 4000 cGy in 20 fxs was given in the surgical arm and 6000 cGy in 30 fxs in the non surgical arm. Treatments were given at 200 cGy/fx. once a day, on a 2 weeks on, 2 weeks off basis. The RTOG Acute Radiation Morbidity Scoring Criteria was used to grade pneumonitis. Post-operative complications were defined as occurring early (less than or equal to 30 days) or late (greater than 30 days) following surgery. Results: Sixteen of the 33 patients went to surgery. Grade 3 radiation pneumonitis developed in 4 of the 33 patients (12%). There were no episodes of Grade 4 pneumonitis. Grade 3 pneumonitis occured in: One patient in Group 1, (RT dose 5800 cGy), 2 pts in Group 2 (RT dose 4000 cGy and 6000 cGy, respectively), and 1 pt in Group 3 (RT dose 6000 cGy). Major post-operative complications occurred in 6 of the 16 patients (37.5%) who went to surgery. In Group 1, 1 pt. required oxygen supplementation secondary to a significant

Objective: To study the relationship between of serum concentrations of CYFRA21-1 and to pathological staging in patients with non-small cell lung cancer. Methods: Serum concentrations of CYFRA21-1 were determined with IRMA in 224 patients with non-small cell lung cancer. Results: The serum CYFRA21-1 levels in patients with non-small cell lung carcinoma increased gradually as the tumor size enlarged. Levels in patients of T2 and T3 stages were significantly higher than those in patients of T1 stage, but the difference between those in patients of T2 stage and T3 stage were not significant. The serum CYFRA21-1 levels also increased as the number of lymph nodes with metastasis increased. Differences of serum levels of CYFRA21-1 in patients of consecutive lymph node stages were all significant. Conclusion: Preoperative detection of the serum concentration of CYFRA21-1 in patient with non-small cell lung cancer has important clinical significance on the judgement of T, N stages. (authors)

A study was made on acid-base metabolism in early posthemorrhagic period as exemplified by examination of patients presenting with gastrointestinal hemorrhage. It has been ascertained that hemorrhage is accompanied by a mixed variant of the acid-base state (ABS) deviation, namely metabolic lactate-acidosis and respiratory alkalosis. In the time-related course of posthemorrhagic period such deviations persist in patients with lethal outcome; with the disease running a favourable course the above deviations are found to return to normal quite soon. The development of complications leads to staging in ABC, its stages being as follows: stage I--the initial stage, stage II--persisting metabolic acidosis and respiratory alkalosis, stage III--alkalosis, stage IV--normalization, with stage III of ABS being encouraged by hypocapnia caused by function disorders of the lungs in early posthemorrhagic period, normalization of cell metabolism, increase in the rate of urination as a reflection of the third earlier identified stage of water metabolism, with the H+ excretion in the urine at the previous level. The identified ABS stage III threatens coming trouble, being accompanied by metabolic deviations together with a risk of function disorder of the myocardium.

Concurrent chemoradiotherapy (CRT) is considered standard for inoperable stage III non-small cell lung cancer (NSCLC). Consolidation chemotherapy (CC) following CRT is intended to further improve outcomes, yet studies have shown discordant results. This phase III study assessed CRT followed by best supportive care (BSC) or consolidation with oral vinorelbine and cisplatin. Patients received two cycles of oral vinorelbine (50 mg/m{sup 2} days 1, 8 and 15) + cisplatin (20 mg/m{sup 2} days 1-4) q4w + radiotherapy (RT; 66 Gy). Patients with at least stable disease (SD) were randomised to either two cycles oral vinorelbine (60-80 mg/m{sup 2} days 1 and 8) + cisplatin (80 mg/m{sup 2} day 1) q3w + BSC or BSC alone. Primary endpoint was progression-free survival (PFS). A total of 279 patients were enrolled for CRT and 201 patients were randomised to CC or BSC. Both CRT and CC were well tolerated, with limited radiation-mediated grade 3/4 toxicities (CRT/CC/BSC: oesophagitis-related events 12.9 %/3.1 %/0 %; grade 3 pneumonitis 0 %/0 %/2 %) and chemotherapy-mediated grade 3/4 toxicities (CRT/CC: neutropenia 11.2 %/22.1 %; leukopenia 18.3 %/26.7 %; grade 3 nausea 5.0 %/2.3 %, grade 3 vomiting 3.2 %/3.5 %). Median PFS from randomisation was 6.4 (5.0-8.7) and 5.5 (3.8-7.4) months in the CC and BSC arms (hazard ratio, HR = 0.93 [0.69-1.26]; p = 0.63), respectively; median overall survival (OS) 20.8 (13.5-25.3) and 18.5 (13.6-24.7) months, respectively. Consolidation chemotherapy after concurrent CRT did not prolong PFS or OS. Concurrent RT with oral vinorelbine and cisplatin demonstrated a favourable safety profile and represents a suitable treatment regimen for inoperable stage III NSCLC. (orig.)

Full Text Available Normal 0 false false false EN-US X-NONE X-NONE Lung cancer is a common disease and is a leading cause of death in many countries. The most kind of lung cancer was Non Small Cell Lung Cancer. The management of lung cancer is directed by an optimal staging of the tumour. On 1998, integrated positron emission tomography (PET-computed tomography (CT was published. PET-CT is an anatomo-metabolic imaging modality that has recently been introduced to clinical practice and combines two different techniques: CT, which provides very detailed anatomic information; and PET, which provides metabolic information. One of the advantages of PET/CT is the improved image interpretation. There wasbetter results for PET/CT in the staging of non small cell lung cancer in comparison with CT nor PET alone. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

Purpose: At our center, approximately 30% of radical radiotherapy (RRT) candidates become ineligible for RRT for non-small-cell lung cancer (NSCLC) after positron emission tomography (PET). We hypothesized that early cancer death rates would be lower in patients receiving RRT after PET staging compared with conventionally staged patients. Methods and Materials: Two prospective cohorts were compared. Cohort 1 consisted of all participants in an Australian randomized trial from our center given 60 Gy conventionally fractionated RRT with or without concurrent carboplatin from 1989 to 1995. Eligible patients had Stage I-III, Eastern Cooperative Oncology Group status 0 or 1, <10% weight loss, and had not undergone PET. Cohort 2 included all RRT candidates between November 1996 and April 1999 who received RRT after PET staging and fulfilled the above criteria for stage, Eastern Cooperative Oncology Group status, and weight loss. Results: Eighty and 77 eligible patients comprised the PET and non-PET groups, respectively. The PET-selected patients had significantly less weight loss; 73% and 49% of the PET and non-PET patients, respectively, received chemotherapy. The median survival was 31 months for PET patients and 16 months for non-PET patients. Mortality from NSCLC and other causes in the first year was 17% and 8% for PET patients and 32% and 4% for non-PET patients, respectively. The hazard ratio for NSCLC mortality for PET vs. non-PET patients was 0.49 (p=0.0016) on unifactorial analysis and was 0.55 (p = 0.0075) after adjusting for chemotherapy, which significantly improved survival. Conclusion: Patients selected for RRT after PET have lower early cancer mortality than those selected using conventional imaging

From June 1978 to March 1984, 311 patients with lung cancer were registered at the radiological department of National Takasaki Hospital. One hundred fifty-one of them, who had been verified histologically and irradiated with total doses of more than 60 Gy for the primary lung tumor, were analized. Many patients were more than 60 years old (82 %) and had squamous cell carcinoma (64 %). These percentages may be associated with distributions of patients treated by radiotherapy because of inoperability. The five-year-relative survival rate was 13 % in all patients (54 % for Stage I, 32 % for Stage II, 0 % for Stage III, 10 % for Stage IV). Comparing squamous cell carcinoma and adenocarcinoma, the latter had a better prognosis for two years, but over three years, squamous cell carcinoma did. The five-year survival rate was 10 % for squamous cell carcinoma and 6 % for adenocarcinoma, showing no statistically significant difference. No predominant differences of prognosis between the older group (more than 70 years old) and the younger group (less than 70 years old) was demonstrated. Thus, old age is not always a factor in bad prognosis. (author)

Purpose: To document the penetration of clinical trial results, practice guidelines, and appropriateness criteria into national practice, we compared the use of components of staging and treatment for lung cancer among patients treated in 2006-2007 with those used in patients treated in 1998-1999. Methods and Materials: Patient, staging work-up, and treatment characteristics were extracted from the process survey database of the Quality Research in Radiation Oncology (QRRO), consisting of records of 340 patients with locally advanced non-small cell lung cancer (LA-NSCLC) at 44 institutions and of 144 patients with limited-stage small cell lung cancer (LS-SCLC) at 39 institutions. Data were compared for patients treated in 2006-2007 versus those for patients treated in 1998-1999. Results: Use of all recommended procedures for staging and treatment was more common in 2006-2007. Specifically, disease was staged with brain imaging (magnetic resonance imaging or computed tomography) and whole-body imaging (positron emission tomography or bone scanning) in 66% of patients with LA-NSCLC in 2006-2007 (vs 42% in 1998-1999, P=.0001) and in 84% of patients with LS-SCLC in 2006-2007 (vs 58.3% in 1998-1999, P=.0011). Concurrent chemoradiation was used for 77% of LA-NSCLC patients (vs 45% in 1998-1999, P<.0001) and for 90% of LS-SCLC patients (vs 62.5% in 1998-1999, P<.0001). Use of the recommended radiation dose (59-74 Gy for NSCLC and 60-70 Gy as once-daily therapy for SCLC) did not change appreciably, being 88% for NSCLC in both periods and 51% (2006-2007) versus 43% (1998-1999) for SCLC. Twice-daily radiation for SCLC was used for 21% of patients in 2006-2007 versus 8% in 1998-1999. Finally, 49% of patients with LS-SCLC received prophylactic cranial irradiation (PCI) in 2006-2007 (vs 21% in 1998-1999). Conclusions: Although adherence to all quality indicators improved over time, brain imaging and recommended radiation doses for stage III NSCLC were used in <90% of cases. Use

Full Text Available Abstract Purpose To evaluate the clinical efficacy and toxicity of stereotactic body radiation therapy (SBRT using extracranial gamma knife in patients with mainly bulky inoperable early stage non-small cell lung carcinoma (NSCLC. Materials and methods A total of 43 medically inoperable patients with mainly bulky Stage I/II NSCLC received SBRT using gamma knife were reviewed. The fraction dose and the total dose were determined by the radiation oncologist according to patients' general status, tumor location, tumor size and the relationship between tumor and nearby organ at risk (OAR. The total dose of 34~47.5 Gy was prescribed in 4~12 fractions, 3.5~10 Gy per fraction, one fraction per day or every other day. The therapeutic efficacy and toxicity were evaluated. Results The median follow-up was 22 months (range, 3-102 months. The local tumor response rate was 95.35%, with CR 18.60% (8/43 and PR 76.74% (33/43, respectively. The local control rates at 1, 2, 3, 5 years were 77.54%, 53.02%, 39.77%, and 15.46%, respectively, while the 1- and 2-year local control rates were 75% and 60% for tumor ≤3 cm; 84% and 71% for tumor sized 3~5 cm; 55% and 14.6% for tumor sized 5~7 cm; and 45%, 21% in those with tumor size of >7 cm. The overall survival rate at 1, 2, 3, 5 years were 92.04%, 78.04%, 62.76%, 42.61%, respectively. The toxicity of stereotactic radiation therapy was grade 1-2. Clinical stages were significantly important factor in local control of lung tumors (P = 0.000. Both clinical stages (P = 0.015 and chemotherapy (P = 0.042 were significantly important factors in overall survival of lung tumors. Conclusion SBRT is an effective and safe therapy for medically inoperable patients with early stage NSCLC. Clinical stage was the significant prognostic factors for both local tumor control and overall survival. The toxicity is mild. The overall local control for bulky tumors is poor. Tumor size is a poor prognostic factor, and the patients for

Thoracic radiotherapy is a major treatment modality of stage III non-small cell lung cancer. The normal lung tissue is sensitive to radiation and radiation pneumonitis is the most important dose-limiting complication of thoracic radiation therapy. This study was performed to identify the clinical and dosimetric parameters related to the risk of radiation pneumonitis after definitive radiotherapy in stage III non-small cell cancer patients. The medical records were reviewed for 49 patients who completed definitive radiation therapy for locally advanced non-small cell lung cancer from August 2000 to February 2010. Radiation therapy was delivered with the daily dose of 1.8 Gy to 2.0 Gy and the total radiation dose ranged from 50.0 Gy to 70.2 Gy (median, 61.2 Gy). Elective nodal irradiation was delivered at a dose of 45.0 Gy to 50.0 Gy. Seven patients (14.3%) were treated with radiation therapy alone and forty two patients (85.7%) were treated with chemotherapy either sequentially or concurrently. Twenty-five cases (51.0%) out of 49 cases experienced radiation pneumonitis. According to the radiation pneumonitis grade, 10 (20.4%) were grade 1, 9 (18.4%) were grade 2, 4 (8.2%) were grade 3, and 2 (4.1%) were grade 4. In the univariate analyses, no clinical factors including age, sex, performance status, smoking history, underlying lung disease, tumor location, total radiation dose and chemotherapy were associated with grade ≥2 radiation pneumonitis. In the subgroup analysis of the chemotherapy group, concurrent rather than sequential chemotherapy was significantly related to grade ≥2 radiation pneumonitis comparing sequential chemotherapy. In the univariate analysis with dosimetric factors, mean lung dose (MLD), V20, V30, V40, MLDipsi, V20ipsi, V30ipsi, and V40ipsi were associated with grade ≥2 radiation pneumonitis. In addition, multivariate analysis showed that MLD and V30 were independent predicting factors for grade ≥2 radiation pneumonitis. Concurrent

In contrast to lung cancer with ground-glass opacity, the radiological investigation of solid lung cancer has not been well examined. The aim of this study was to explore chest computed tomography (CT) and positron emission tomography (PET)/CT findings with regard to outcomes after lung cancer surgery in order to radiologically classify clinical stage IA lung cancers by tumour aggressiveness. Three hundred and fifteen clinical stage IA patients were analysed. Four groups were defined by tumour solidity on CT and by the standardized uptake value (SUV) index on PET-CT (tumour maximum SUV/mean right liver lobe SUV). We analysed the association between radiological findings and both pathological invasiveness and postoperative outcome. Group A (n = 84) had an SUV index <1.0 and non-solid tumours, Group B (n = 24) had an SUV index <1.0 and solid tumours, Group C (n = 54) had an SUV index ≥1.0 and non-solid tumours, while Group D (n = 153) had an SUV index ≥1.0 and solid tumours. Invasive lung cancer was found in 2/84 (2.4%) patients in Group A, 1/24 (4.2%) in Group B, 13/54 (24.1%) in Group C and 58/153 (37.9%) in Group D (P < 0.01). The 5-year recurrence-free rate was 100% in Groups A and B, 90.3% in C and 65.7% in D (P < 0.01). The cancer-specific survival rate was 100% in A and B, 94.6% in C and 81.7% in D (P < 0.01). The present results suggest that preoperative PET/CT and thin-section CT findings provide important information for a selection of surgical procedures for clinical stage IA lung cancers. In clinical stage IA lung cancers displaying solid or non-solid density in thin-section findings, an SUV index <1.0 may be a better criterion for detecting non-aggressive lung cancer even in solid lung cancers. © The Author 2014.

Clinical guidelines recommend adjuvant chemotherapy for high-risk patients with Stage II-III colorectal cancer. However, chemotherapeutic administration rates differ significantly between hospitals. We assessed the prognostic benefit of adjuvant chemotherapy in patients with Stage IIb/c colorectal cancer, and the prognostic impact of interhospital variations in the administration of adjuvant chemotherapy for Stage II-III colorectal cancer. We conducted a multicentre, retrospective study of 17 757 patients with Stage II-III colorectal cancer treated between 1997 and 2008 in 23 hospitals in Japan. Hospitals were classified as high-rate (rate > 42.8%) or low-rate (rate ≤ 42.8%), chemotherapy prescribing clinics. The 5-year overall survival (OS) of patients with Stage II-III colorectal cancer receiving adjuvant chemotherapy was significantly higher than for those not receiving adjuvant chemotherapy (85.7% vs 79.2%, P colorectal cancer (both P colorectal cancer who received adjuvant chemotherapy, with patients who were treated in hospitals with high adjuvant chemotherapy rates demonstrating better prognoses.

Previous studies have shown a correlation between expression of the EGF receptor type III mutation (EGFRvIII) and a more malignant phenotype of various cancers including: non-small-cell lung cancer, glioblastoma multiforme, prostate cancer and breast cancer. Thus, a detailed molecular genetic...... understanding of how the EGFRvIII contributes to the malignant phenotype is of major importance for future therapy. The GeneChip Hu6800Set developed by Affymetrix was used to identify changes in gene expression caused by the expression of EGFRvIII. The cell line selected for the study was an EGF receptor...... negative small-cell-lung cancer cell line, GLC3, stably transfected with the EGFRvIII gene in a Tet-On system. By comparison of mRNA levels in EGFRvIII-GLC3 with those of Tet-On-GLC3, it was found that the levels of mRNAs encoding several transcription factors (ATF-3, JunD, and c-Myb), cell adhesion...

Fourty two cases of lung cancer in A-bomb survivors experienced between 1971 and 1975 were compared to non-exposure cases with lung cancer, and discussed. The mean age of A-bomb survivors with lung cancer was 68.7 year old, and that of control cases was 60 year old. The incidence ratio of male to female in the group was 4 : 1, and that of control group was 5 : 1. Occupation was one of the predisposing causes, but patients who had engaged in the occupation which was considered to predispose lung cancer were three. Among 39 patients with lung cancer whose smoking histories were clarified, 20.5 per cent was nonsmoker, and 69.3 per cent was heavy smoker. Among 39 patients whose cancer histories were clarified, 28.2 per cent of the patients had family history of cancer. Subjective symptoms of this disease were cough, sputum, bloody sputum and chest pain, and some had no symptoms. Seventeen cases (40.5 per cent) were detected in the physical examination for the A-bomb survivors. For the early detection of lung cancer in A-bomb survivors, patients with high risk should be selected to have received clearly established diagnosis. Histologically, squamous cell carcinoma was seen in many cases, following adenoma, and undifferenciated large cell carcinoma and small cell carcinoma. Disturbances in pulmonary functions were obstructive ventilation, high rate of residual air, lowered diffusions ability. Therapy was operation in stage I, chemotherapy and radiation therapy in stage II and stage III. (Kanao, N.)

Treatment results of patients aged 75 years or older (elderly group) with non-small-cell lung cancer were compared with those of patients aged 74 years or younger (younger group). In patients with stage III disease, radiotherapy alone resulted in a median survival of 11.5 months in the younger group and 5.5 months in the elderly group. There was a significant difference in survival rate between the two groups (P=0.0008). Moreover, the elderly group patients more frequently died of pneumonia and radiation pneumonitis than the younger group patients. However, results of radiotherapy were similar in the two groups of patients with stage I and II disease. Accordingly, these findings suggested that radiotherapy is an appropriate treatment modality for elderly lung cancer patients, but that individualized radiotherapy is needed for those with locally advanced stage.

The optimal chemotherapy regimen to use with radiotherapy in stage III non-small-cell lung cancer is unknown. Here, we compare the outcome of patents treated within the Veterans Health Administration with either etoposide-cisplatin (EP) or carboplatin-paclitaxel (CP). We identified patients treated with EP and CP with concurrent radiotherapy from 2001 to 2010. Survival rates were compared using Cox proportional hazards regression models with adjustments for confounding provided by propensity score methods and an instrumental variables analysis. Comorbidities and treatment complications were identified through administrative data. A total of 1,842 patients were included; EP was used in 27% (n = 499). Treatment with EP was not associated with a survival advantage in a Cox proportional hazards model (hazard ratio [HR], 0.97; 95% CI, 0.85 to 1.10), a propensity score matched cohort (HR, 1.07; 95% CI, 0.91 to 1.24), or a propensity score adjusted model (HR, 0.97; 95% CI, 0.85 to 1.10). In an instrumental variables analysis, there was no survival advantage for patients treated in centers where EP was used more than 50% of the time as compared with centers where EP was used in less than 10% of the patients (HR, 1.07; 95% CI, 0.90 to 1.26). Patients treated with EP, compared with patients treated with CP, had more hospitalizations (2.4 v 1.7 hospitalizations, respectively; P kidney disease/dehydration (30.5% v 21.2%, respectively; P patients treated with EP versus CP had similar overall survival, but EP was associated with increased morbidity. © 2014 by American Society of Clinical Oncology.

Non-alcoholic fatty liver disease (NAFLD) has become one of the most frequent causes of chronic liver disease. Currently, therapeutic options for NAFLD patients are limited, but new pharmacologic agents are being investigated in the course of clinical trials. Because most of these studies are focusing on patients with fibrosis stages II and III (according to Kleiner), non-invasive identification of patients with intermediate fibrosis stages (II and III) is of increasing interest. Evaluation of NAFLD Fibrosis Score (NFS) and liver stiffness measurement (LSM) for prediction of fibrosis stages II/III. Patients with histologically confirmed NAFLD diagnosis were included in the study. All patients underwent a clinical and laboratory examination as well as a LSM prior to liver biopsy. Predictive value of NFS and LSM with respect to identification of fibrosis stages II/III was assessed. 134 NAFLD patients were included and analyzed. Median age was 53 (IQR 36 - 60) years, 55 patients (41 %) were female. 82 % of our patients were overweight/obese with typical aspects of metabolic syndrome. 84 patients (66 %) had liver fibrosis, 42 (50 %) advanced fibrosis. LSM and NFS correlated with fibrosis stage (r = 0.696 and r = 0.685, respectively; p stages II/III. If both criteria were met, probability of fibrosis stage II/III was 61 %. If none of the two criteria was met, chance for fibrosis stage II/III was only 6 % (negative predictive value 94 %). Combination of LSM and NFS enables identification of patients with significant probability of fibrosis stage II/III. Accordingly, these tests, especially in combination, may be a suitable screening tool for fibrosis stages II/III in NAFLD. The use of these non-invasive methods might also help to avoid unnecessary biopsies. © Georg Thieme Verlag KG Stuttgart · New York.

The fibronectin III-1 domain activates a PI3-Kinase/Akt signaling pathway leading to αvβ5 integrin activation and TRAIL resistance in human lung cancer cells

Fibronectin is a mechanically sensitive protein which is organized in the extracellular matrix as a network of interacting fibrils. The lung tumor stroma is enriched for fibronectin which is thought to contribute to metastasis and drug resistance. Fibronectin is an elastic, multi-modular protein made up of individually folded domains, some of which can stretch in response to increased mechanical tension. Very little is known about the relationship of fibronectin’s unfolded domains to lung cancer resistance to chemotherapy. In the present study, we evaluated the impact of unfolding the first Type III domain of fibronectin (FnIII-1c) on TNF-related apoptosis inducing ligand (TRAIL) resistance. NCI-H460 non-small cell lung cancer cells were treated with FnIII-1c then assessed for TRAIL-induced apoptosis. Subsequent analysis of FnIII-1c-mediated signaling pathways was also completed. Human non-small cell lung cancer tissue sections were assessed for the expression of vitronectin by immunohistochemistry. FnIII-1c inhibited TRAIL-induced activation of caspase 8 and subsequent apoptosis in NCI-H460 lung cancer cells. FnIII-1c treatment was associated with the activation of the phosphatidylinositol-3-kinase/alpha serine/threonine kinase (PI3K/Akt) pathway and the αvβ5 integrin receptor for vitronectin, both of which were required for TRAIL resistance. Immunohistochemical staining of sections from non-small cell lung cancers showed that vitronectin was localized around blood vessels and in the tumor-stroma interface. Unfolding of Type III domains within the fibronectin matrix may promote TRAIL resistance through the activation of a PI3K/Akt/αvβ5 signaling axis and point to a novel mechanism by which changes in secondary structure of fibronectin contribute to cancer cell resistance to apoptosis

Limited-stage small cell lung cancer: current chemoradiotherapy treatment paradigms.

Stinchcombe, Thomas E; Gore, Elizabeth M

2010-01-01

In the U.S., the prevalence of small cell lung cancer (SCLC) is declining, probably reflecting the decreasing prevalence of tobacco use. However, a significant number of patients will receive a diagnosis of SCLC, and approximately 40% of patients with SCLC will have limited-stage (LS) disease, which is potentially curable with the combination of chemotherapy and radiation therapy. The standard therapy for LS-SCLC is concurrent chemoradiotherapy, and the 5-year survival rate observed in clinical trials is approximately 25%. The standard chemotherapy remains cisplatin and etoposide, but carboplatin is frequently used in patients who cannot tolerate or have a contraindication to cisplatin. Substantial improvements in survival have been made through improvements in radiation therapy. Concurrent chemoradiotherapy is the preferred therapy for patients who are appropriate candidates. The optimal timing of concurrent chemoradiotherapy is during the first or second cycle, based on data from meta-analyses. The optimal radiation schedule and dose remain topics of debate, but 1.5 Gy twice daily to a total of 45 Gy and 1.8-2.0 Gy daily to a total dose of 60-70 Gy are commonly used treatments. For patients who obtain a near complete or complete response, prophylactic cranial radiation reduces the incidence of brain metastases and improves overall survival. The ongoing Radiation Therapy Oncology Group and Cancer and Leukemia Group B and the European and Canadian phase III trials will investigate different radiation treatment paradigms for patients with LS-SCLC, and completion of these trials is critical.

To evaluate the clinical value of the multi-detector row computed tomography (MDCT) in the quantitative assessment of lung volumes and to assess the relationship between the MDCT results and disease severity as determined by a pulmonary function test (PFT) in Chronic Obstructive Pulmonary Disease (COPD) patients. We performed a PFT and MDCT on 39 COPD patients. Using the GOLD classifications, we divided the patients into three groups according to disease severity; stage I (mild, n = 10), stage II (moderate, n = 15), and stage III (severe, n = 14). Using the pulmo-CT software program, we measured the proportion of lung volumes with attenuation values below -910 and -950 HU. The mean FEV1 (% of predicted) and FEV1/FVC was 82.2 ± 2% and 66.2 ± 3% in stage I, 53.5 ± 11% and 52 ± 6% in stage II, and 32.3 ± 7% and 44.2% ± 13% in stage III, respectively. Differences in lung volume percentage at each of the thresholds (-910 and -950 HU) among the 3 stages were statistically significant (ρ < 0.01, ρ < 0.01) and correlated well with the FEV1 and FEV1/FVC (r = -0.803, r -0.766, r = -0.817, and r = -0.795, respectively). The volumetric measurement obtained by MDCT provides an accurate means of quantifying pulmonary emphysema

A total of forty patients with resected N2 stage non-small cell lung cancer treated with postoperative adjuvant radiation therapy between Jan. 1975 and Dec. 1990 at the Department of Radiation Oncology, Yonsei University College of Medicine, Yonsei Cancer Center were retrospectively analysed to evaluate whether postoperative radiation therapy improves survival. Patterns of failure and prognostic factors affecting survival were also analysed. The 5 year overall and disease free survival rate were 26.3%, 27.3% and median survival 23.5 months. The 5 year survival rates by T-stage were T1 66.7%, T2 25.6% and T3 12.5%. Loco-regional failure rate was 14.3% and distant metastasis rate was 42.9% and both 2.9%. Statistically significant factor affecting distant failure rate was number of positive lymph nodes(>= 4). This retrospective study suggests that postoperative radiation therapy in resected N2 stage non-small cell lung cancer can reduce loco-regional recurrence and may improve survival rate as compared with other studies which were treated by surgery alone. Further study of systemic control is also needed due to high rate of distant metastasis

To explore clinical value of combined detection of CYFRA21-1, NSE and CEA in classification and staging of patients with lung cancer, the CYFRA21-1, NSE and CEA levels in pleural effusion in 330 patients with lung cancer and in 43 patients with benign were detected by the electrochemiluminescence. The results showed that CYFRA21-1, NSE and CEA levels in pleural effusion in patients with lung cancer group were significantly higher than that of in benign group (P<0.01). The positive rate of tumor markers in different pathological type lung cancer were different,which CYFRA21-1 positive rate in squamous cell cancer group was highest with 65.5%; CEA positive rate in glands cancer group was supreme with 65.0%; the NSE positive rate in differentiation cancer group was highest with 79.5%. The positive rate in three markers combined detection was higher than that in one item detection. The tumor marker levels in lung cancer were positively related with clinical staging. The higher of tumor marker levels and the more late of clinical staging, and the clinical III∼IV period was obviously higher than that I∼II period (P<0.05). The combined detection of CYFRA21-1, NSE and CEA may enhance the positive rate in lung cancer detection, and may have significant clinical value in the classification and staging of patients with lung cancer.

Purpose: To evaluate the practice process using the national average (Na); to compare differences in the process of care by age group; and to provide a preliminary outcome data for limited-stage small-cell lung cancer in Japan. Methods and Materials: The Patterns of Care Study conducted a nationwide survey of the care process for Stage I-III small-cell lung cancer in Japan. Patients were divided into three age groups: <65 years (younger group, n = 73); between 65 and 74 years (intermediate group, n = 81); and ≥75 years (elderly group, n = 20). Results: The NA for the total dose was 49.0 Gy, and for use of photon energy ≥6 MV, chemotherapy, and prophylactic cranial irradiation was 77.3%, 93.2%, and 1.69%, respectively. Age stratification had no impact on the variables of radiotherapy (RT) such as total dose and field size. Only 37% of patients received chemotherapy and thoracic RT concurrently. The proportion of patients who received chemotherapy and RT concurrently was 44%, 27%, and 25% of the younger, intermediate, and elderly groups, respectively (p = 0.029). Etoposide and cisplatin were less frequently used in the elderly group (≥75 years old). Overall survival at 3 years for the entire group was 26%. The 3-year survival rate was 30% in the younger group, 28% in the intermediate group, and 9% in the elderly group. Variables found to have a significant impact on survival by multivariate analysis were the use of chemotherapy (p = 0.030), age (p 0.032), and T stage (p = 0.042). Conclusion: Calculated NAs showed that the results of clinical study had favorably penetrated into the practice process in Japan. The results demonstrated that patient age significantly influenced the process of chemotherapy such as the use of etoposide and cisplatin for limited-stage small-cell lung cancer in Japan. More concurrent chemotherapy and thoracic RT and the application of prophylactic cranial irradiation for complete responders need to be investigated in the future

Full Text Available ABSTRACT Objective: Patients with lung cancer experience different feelings and reactions, based on their family, social, cultural, and religious backgrounds, which are a source of great distress, not only for the patients but also for their family caregivers. This study aimed to evaluate the impact that lung cancer stage and quality of life (QoL of lung cancer patients have on caregiver burden. Methods: This was a prospective cross-sectional study. Consecutive patient-caregiver dyads were selected and asked to complete the Hospital Anxiety and Depression Scale and the Medical Outcomes Study 36-item ShortForm Health Survey (SF-36. Family caregivers also completed the Caregiver Burden Scale. Group-based modeling was used in order to identify patients with early- or advanced-stage cancer (IA to IIIA vs. IIIB to IV plus non-impaired or impaired QoL (SF36 total score > 50 vs. ≤ 50. Patient-caregiver dyads were stratified into four groups: early-stage cancer+non-impaired QoL; advanced-stage cancer+non-impaired QoL; early-stage cancer+impaired QoL; and advanced-stage cancer+impaired QoL. Results: We included 91 patient-caregiver dyads. The majority of the patients were male and heavy smokers. Family caregivers were younger and predominantly female. The burden, QoL, level of anxiety, and level of depression of caregivers were more affected by the QoL of the patients than by their lung cancer stage. The family caregivers of the patients with impaired QoL showed a higher median burden than did those of the patients with non-impaired QoL, regardless of disease stage. Conclusions: Caregiver burden is more affected by patient QoL than by lung cancer stage.

Sixty-nine patients with small cell carcinoma of the lung were treated at Kobe University Hospital from January 1972 to August 1982. The results of treatment were as follows. i) Five year survival rate was greater for stage III cases than for stage IV cases (p < 0.05). ii) Differences of therapeutic effects between two periods, before and after 1977, were evaluated. Cases with stage III small cell carcinoma showed a tendency forwards improved survival rate after 1977, however, no significant difference was seen with stage IV cases before and after 1977. iii) In terms of what therapy improved the survival rate, among stage III patients, 7 were treated with combination chemotherapy and radiotherapy (group A), 14 were treated with single agent chemotherapy and radiotherapy (group B) and 4 with only radiotherapy. Among stage IV cases, 9 belonged to group A and 20 to group B. Better survival rate was seen in group A compared with group B with regard to stage III, although it did not quite reach statistical significance (0.05 < p < 0.1), whereas no significant survival difference was seen with stage IV disease. iv) Significant differences of survival rate were seen between CR (complete remission) and PR (partial remission) patients (p < 0.05) and between CR and PD (progressive disease) patients (p < 0.01), as classified by preliminary therapeutic effects. v) No significant difference in survival rate was noted among the histologic subtypes.

Increased red blood cell distribution width associates with cancer stage and prognosis in patients with lung cancer.

Directory of Open Access Journals (Sweden)

Yasuko Koma

Full Text Available BACKGROUND: Red cell distribution width (RDW, one of many routinely examined parameters, shows the heterogeneity in erythrocyte size. We investigated the association of RDW levels with clinical parameters and prognosis of lung cancer patients. METHODS: Clinical and laboratory data from 332 patients with lung cancer in a single institution were retrospectively studied by univariate analysis. Kaplan-Meier survival analysis and Cox proportional hazard models were used to examine the effect of RDW on survival. RESULTS: THE RDW LEVELS WERE DIVIDED INTO TWO GROUPS: high RDW (>=15%, n=73 vs. low RDW, n=259 (<15%. Univariate analysis showed that there were significant associations of high RDW values with cancer stage, performance status, presence of other disease, white blood cell count, hemoglobin, mean corpuscular volume, platelet count, albumin level, C-reactive protein level, and cytokeratin 19 fragment level. Kruskal-Wallis tests revealed an association of RDW values with cancer stage in patients irrespective of comorbidity (patient with/without comorbidity: p<0.0001, patient without comorbidity: p<0.0001. Stages I-IV lung cancer patients with higher RDW values had poorer prognoses than those with lower RDW values (Wilcoxon test: p=0.002. In particular, the survival rates of stage I and II patients (n=141 were lower in the high RDW group (n=19 than in the low RDW group (n=122 (Wilcoxon test: p<0.001. Moreover, multivariate analysis showed higher RDW is a significant prognostic factor (p=0.040. CONCLUSION: RDW is associated with several factors that reflect inflammation and malnutrition in lung cancer patients. Moreover, high levels of RDW are associated with poor survival. RDW might be used as a new and convenient marker to determine a patient's general condition and to predict the mortality risk of lung cancer patients.

Stage IA non-small-cell lung cancer cases have been recognized as having a low risk of relapse; however, occasionally, relapse may occur. To predict clinical outcome in Stage IA non-small-cell lung cancer patients, we searched for chimeric transcripts that can be used as biomarkers and identified a novel chimeric transcript, RUNX1-GLRX5, comprising RUNX1, a transcription factor, and GLRX5. This chimera was detected in approximately half of the investigated Stage IA non-small-cell lung cancer patients (44/104 cases, 42.3%). Although there was no significant difference in the overall survival rate between RUNX1-GLRX5-positive and -negative cases (P = 0.088), a significantly lower relapse rate was observed in the RUNX1-GLRX5-positive cases (P = 0.039), indicating that this chimera can be used as a biomarker for good prognosis in Stage IA patients. Detection of the RUNX1-GLRX5 chimeric transcript may therefore be useful for the determination of a postoperative treatment plan for Stage IA non-small-cell lung cancer patients. © The Author 2015.

3DCRT treatments are the most commonly used techniques in the treatment of lung and breast cancers. The purpose of this study was to perform the BMOA of the 3DCRT plans designed for the treatment of breast and lung cancers utilizing HART program (Med. Phys. 36, p.2547(2009)). The BMOA parameters include normal tissue complication probability (NTCP), tumor control probability (TCP), and the complication-free tumor control probability (P+). The 3DCRT plans were designed for (i) the palliative treatment of 8 left lung cancer patients (CPs) at early stage (m=8), (ii) the curative treatment of 8 left lung CPs at stages II and III (k=8), and (iii) the curative treatment of 8 left breast CPs (n=8). The NTCPs were noticeably small (esophagus in lung CPs (k=8). Assessments of the TCPs and P+s also indicated good improvements in local tumor control in all plans. Homogeneous target coverage and improved dose conformality were the major advantages of such techniques in the treatment of breast cancer. These achievements support the efficacy of the 3DCRT techniques for the efficient treatment of various types of cancer.

Treatment guidelines for colon cancer recommend colectomy with lymphadenectomy of at least 12 lymph nodes for patients with stage I to stage III disease as surgery adherence (SA) and adjuvant chemotherapy for individuals with stage III disease. Herein, the authors evaluated adherence to these guidelines among older patients in Texas with colon cancer and the associated survival outcomes. Using Texas Cancer Registry data linked with Medicare data, the authors included patients with AJCC stage II and III colon cancer who were aged ≥66 years and diagnosed between 2001 and 2011. SA and adjuvant chemotherapy adherence rates to treatment guidelines were estimated. The chi-square test, general linear regression, survival probability, and Cox regression were used to identify factors associated with adherence and survival. The rate of SA increased from 47.2% to 84% among 6029 patients with stage II or stage III disease from 2001 to 2011, and the rate of adjuvant chemotherapy increased from 48.9% to 53.1% for patients with stage III disease during the same time period. SA was associated with marital status, tumor size, surgeon specialty, and year of diagnosis. Patient age, sex, marital status, Medicare state buy-in status, comorbidity status, and year of diagnosis were found to be associated with adjuvant chemotherapy. The 5-year survival probability for patients receiving guideline-concordant treatment was the highest at 87% for patients with stage II disease and was 73% for those with stage III disease. After adjusting for demographic and tumor characteristics, improved cancer cause-specific survival was associated with the receipt of stage-specific, guideline-concordant treatment for patients with stage II or stage III disease. The adherence to guideline-concordant treatment among older patients with colon cancer residing in Texas improved over time, and was associated with better survival outcomes. Future studies should be focused on identifying interventions to

To study the significance of nm23, collagen IV and PCNA expressions in non-small cell lung cancer. Expressions of the nm23, collagen IV and PCNA in 84 cases of non-small cell lung cancer were examined with SP immunohistochemical technique. Of the 84 cases, there were squamous cell carcinoma 42, adenocarcinoma 42, stage I 27, stage II 24, stage III 24, and stage IV 9. Statistical analysis was performed with Chi-Square test. Expressions of the nm23, collagen IV and PCNA in 84 cases of non-small cell lung cancer were 60. 7% ( 51/ 84) , 75. 0% ( 63/ 84) and 53. 6% ( 45/ 84) respectively. There was negative correlation between the lymph node metastasis and the expressions of nm23 and collagen IV in squamous cell carcinoma, and the expressions of collagen IV and PCNA were associated with tumor differentiation. No correlation was found between TNM stage and expressions of nm23, collagen IV and PCNA. The results indicate that nm23, collagen IV and PCNA participate the modulation of metastasis of non-small cell lung cancer and that they may be used to evaluate the potential of metastasis.

The advanced forms of multiple myeloma of bone, stage III, or those with a large tumoral mass, characterized by a considerable number of myelomacells, pose difficult problems in treatment. Little progress has been made since the introduction of the alkylating agents, and combined chemotherapy does not seem to be any more effective in terms of survival. It is these severe forms that culminate in painful symptoms which are often difficult to eliminate. The radiosensitivity of myeloma led us to treat 20 patients affected by severe forms of the disease by total body irradiation in two stages, and we analyze here the effects of treatment and the tolerance for this technique

Radiotherapy is the first treatment of choice in cases of inoperable lung cancer. This paper reported the indications and limitations of radiotherapy for squamous cell carcinoma of the lung, based on the results of long-term survivors among non-resected squamous cell carcinoma. Materials consisted of 372 cases of squamous cell carcinoma of the lung treated with radiotherapy at the National Cancer Center Hospital between May 1962 and December 1980. Histopathological diagnosis was confirmed by biopsy in all cases. Among the 372 cases, 8 survived more than 5 years. Analyzing these 8 cases according to the TNM classification of the UICC, 7 were stage I, 1 was stage II, and there were no long-term survivors with stage III or IV. Of the 8 cases only one is alive. Analyzing 7 the fatal cases, 2 succumbed due to hepatic or brain metatasis following local recurrence and one had double primary cancer of the pancreas. The remaining 4 cases did not show recurrence or metastasis and succumbed due to pneumonia or myocardial infarct. (author)

Many different long non-coding RNAs (lncRNAs) have been reported to be abnormally expressed in lung carcinoma and may thus serve as prognostic biomarkers for this disease. We conducted this meta-analysis, which included a total of 30 studies identified via searches of PubMed, Embase, Medline, and Web of Science and included 2912 patients from China (28), Germany (1), and Japan (1), to investigate the prognostic value of different lncRNAs in lung carcinoma. The results revealed that lncRNA transcription levels were significantly associated with overall survival in lung cancer patients (HR:1.46, 95% CI: 1.16-1.83, P = 0.000). However, lncRNA transcription levels were not associated with progression-free survival (PFS) (HR: 1.55, 95% CI: 0.50-4.80, P = 0.449). Further analysis showed that high lncRNA transcription levels were significantly associated with tumour-node-metastasis (TNM) stage (III/IV vs I/II: RR = 1.339, 95% CI: 1.046-1.716, P = 0.012), lymph node metastasis (positive vs negative: RR = 1.442, 95% CI: 1.103-1.885, P = 0.007), and distant metastasis (yes vs no: RR = 3.187,95% CI: 1.393-7.294, P = 0.006). Taken together, the results of our present meta-analysis revealed that lncRNAs may be useful prognostic markers for lung carcinoma and may also have value as biomarkers for TNM stage, lymph node metastasis and distant metastasis.

The aim of this phase I/II dose escalating study was to establish the maximum tolerated dose (MTD) of gemcitabine and paclitaxel given in combination in non-small cell lung cancer (NSCLC). 12 patients with stage IIIB and IV NSCLC received paclitaxel administered intravenously over 1 h followed by gemcitabine given over 30 min on days 1, 8 and 15 every 28 days. Pneumonitis was the principal side-effect observed with 4 patients affected. Of these, 1 experienced grade 3 toxicity after one cycle of treatment and the others had grade 2 toxicity. All 4 cases responded to prednisolone. No other significant toxicities were observed. Of the 8 evaluable patients, 3 had a partial response and 2 had minor responses. The study was discontinued due to this dose-limiting toxicity. The combination of paclitaxel and gemcitabine shows promising antitumour activity in NSCLC, however, this treatment schedule may predispose to pneumonitis.

While surgery is considered standard of care for early stage (I/II), non-small-cell lung cancer (NSCLC), radiotherapy is a widely accepted alternative for medically unfit patients or those who refuse surgery. International guidelines recommend several treatment options, comprising stereotactic body radiation therapy (SBRT) for small tumors, conventional radiotherapy ≥ 60 Gy for larger sized especially centrally located lesions or continuous hyperfractionated accelerated RT (CHART). This study presents clinical outcome and toxicity for patients treated with a dose-differentiated accelerated schedule using 1.8 Gy bid (DART-bid). Between April 2002 and December 2010, 54 patients (median age 71 years, median Karnofsky performance score 70 %) were treated for early stage NSCLC. Total doses were applied according to tumor diameter: 73.8 Gy for < 2.5 cm, 79.2 Gy for 2.5-4.5 cm, 84.6 Gy for 4.5-6 cm, 90 Gy for > 6 cm. The median follow-up was 28.5 months (range 2-108 months); actuarial local control (LC) at 2 and 3 years was 88 %, while regional control was 100 %. There were 10 patients (19 %) who died of the tumor, and 18 patients (33 %) died due to cardiovascular or pulmonary causes. A total of 11 patients (20 %) died intercurrently without evidence of progression or treatment-related toxicity at the last follow-up, while 15 patients (28 %) are alive. Acute esophagitis ≤ grade 2 occurred in 7 cases, 2 patients developed grade 2 chronic pulmonary fibrosis. DART-bid yields high LC without significant toxicity. For centrally located and/or large (> 5 cm) early stage tumors, where SBRT is not feasible, this method might serve as radiotherapeutic alternative to present treatment recommendations, with the need of confirmation in larger cohorts.

No novel chemotherapeutic combinations have demonstrated superior efficacy to etoposide/cisplatin (EP), a standard treatment regimen for extensive-stage small cell lung carcinoma (ES-SCLC) over the past decade. We aimed to compare the efficacy and safety of belotecan/cisplatin (BP) and EP regimens in chemotherapy- and radiotherapy-naïve patients with previously untreated ES-SCLC. We conducted a multi-center, randomized, open-label, parallel-group, phase III clinical study. A total of 157 patients were recruited at 14 centers with 147 patients meeting the inclusion/exclusion criteria and randomized to either BP (n = 71) or EP (n = 76) treatment arms. A non-inferior response rate (RR) in the BP arm, analyzed by intent-to-treat analysis according to Response Evaluation Criteria in Solid Tumors version 1.0 criteria, was used as the primary endpoint. The secondary endpoints were progression-free survival (PFS) and overall survival (OS). In the BP arm, one patient had a complete response, 41 had a partial response (PR), and 17 had stable disease (SD). In the EP arm, 35 patients had PR and 28 had SD. The RR in the BP arm was non-inferior to the EP regimen in patients with ES-SCLC (BP: 59.2 %, EP: 46.1 %, difference: 13.1 %, 90 % two-sided confidence interval: -0.3–26.5, meeting the predefined non-inferiority criterion of -15.0 %). No significant differences in OS or PFS were observed between the treatment arms. Hematologic toxicities, including grade 3/4 anemia and thrombocytopenia, were significantly more prevalent in the BP arm than the EP arm. The RR to the BP regimen was non-inferior to the EP regimen in chemotherapy- and radiotherapy-naïve patients with previously untreated ES-SCLC. Hematologic toxicities were significantly more prevalent in the BP group, indicating that BP should be used with care, particularly in patients with a poor performance status. Further studies assessing PFS and OS are required to validate the superiority of the BP regimen. Clinical

We studied the efficacy of cisplatin-based polychemotherapy for adenocarcinoma of the lung. A total of 136 patients were randomized for treatment with either cyclophosphamide, Adriamycin, cisplatin and mitomycin C (CAPM) or mitomycin C, cytosine arabinoside and tegafur (MCT). Radiation was given to the chests of patients at stage III. The differences in the response rate (35% in the CAPM arm and 13% in the MCT arm) were statistically significant (P less than 0.01). However, the significant difference was observed in stage-IV patients (CAPM, 33%; MCT, 4%; P less than 0.001) and not in stage-III patients (CAPM, 40%; MCT, 40%). The median period of survival was 9.5 months for the CAPM arm and 5.5 months for the MCT arm (P less than 0.035, Wilcoxon-Gehan test; P less than 0.1, log-rank test). Improved median survival for the CAPM regimen was demonstrated only by stage-IV patients (CAPM, 10 months; MCT, 5.5 months; P less than 0.025, Wilcoxon-Gehan test; P less than 0.05, log-rank test). The duration of the response, including PRs and NCs, was significantly different depending on the treatment, showing 5 months for the CAPM arm and 3 months for the MCT arm (P less than 0.05). The significant difference was also only observed in stage-IV patients. Myelosuppression was more severe with CAPM than with the MCT regimen. Nausea and vomiting were significantly increased in patients receiving the CAPM regimen. However, all toxicities were acceptable and there were no treatment-related deaths. We concluded that cisplatin-based chemotherapy, CAPM therapy, was of more benefit to patients with adenocarcinoma of the lung than MCT therapy.

To analyze the clinicopathologic factors related to recurrence and metastasis of stage II or III colon cancer after radical resection. The clinical and pathological data of 628 patients with stage II or III colon cancer after radical resection from Jan. 2005 to Dec. 2008 in our hospital were retrospectively reviewed and analyzed. The overall recurrence and metastasis rate was 28.5% (179/628). The 5-year disease-free survival (DFS) rate was 70.3% and 5-year overall survival (OS) rate was 78.5%. Univariate analysis showed that age, smoking intensity, depth of tumor invasion, lymph node metastasis, TNM stage, gross classification, histological differentiation, blood vessel tumor embolus, tumor gross pathology, multiple primary tumors, preoperative and postoperative serum concentration of CEA and CA19-9, and the regimen of adjuvant chemotherapy were correlated to recurrence and metastasis of colon cancer after radical resection. Multivariate analysis showed that regional lymph node metastasis, TNM stage, the regimen of postoperative adjuvant chemotherapy, and preoperative serum concentration of CEA and CA19-9 were independent factors affecting the prognosis of colon cancer patients. Regional lymph node metastasis, TNM stage, elevated preoperative serum concentration of CEA and CA19-9, the regimen of postoperative adjuvant chemotherapy with single fluorouracil type drug are independent risk factors of recurrence and metastasis in patients with stage II-III colon cancer after radical resection.

In group II, III and IV 0.2, 0.3 and 0.5 mg/kg pingyangmycin were given respectively by marginal vein of ear every other day. 99 Tc m -HMPAO static lung imaging was performed before and 8, 16, 24, 32 d after injection of pingyangmycin. 7 pixel x 5 pixel regions of interest (ROIs) were drawn on the right lung(R) and right upper limb(B), R/B were calculated. Also, 2 ml venous blood was withdrawn for measurement of endothelin by radioimmunoassay. 16 d after pingyangmycin in group IV and 32 d in group I, II and III, all the rabbits were sacrificed. Both lungs were examined immediately under light and electron microscopy. Results: Compared with the control group, there were statistical differences of 99 Tc m -HMPAO lung uptake in group II, III and IV (P 99 Tc m -HMPAO lung imaging can detect early pingyangmycin-induced lung injury. The endothelium of lung microcapillary is presumably the main location site of 99 Tc m -HMPAO abnormal concentration. (authors)

BACKGROUND AND STUDY AIMS: Exact staging of patients with non-small-cell lung cancer (NSCLC) is important to improve selection of resectable and curable patients for surgery. Positron emission tomography with integrated computed tomography (PET/CT) and endoscopic ultrasound guided fine needle...... aspiration biopsy (EUS-FNA) are new and promising methods, but indications in lung cancer staging are controversial. Only few studies have compared the 2 methods. The aim of this study was to assess and compare the diagnostic values of PET/CT and EUS-FNA for diagnosing advanced lung cancer in patients, who...... had both procedures performed. PATIENTS AND METHODS: 27 patients considered to be potential candidates for resection of NSCLC underwent PET/CT and EUS-FNA. Diagnoses were confirmed either by open thoracotomy, mediastinoscopy or clinical follow-up. Advanced lung cancer was defined as tumour...

Combined modality therapy is a standard therapy for patients with unresectable stage III non-small cell lung cancer (NSCLC). Gefitinib is active in advanced NSCLC, and in preclinical models, it potentiates the activity of radiation therapy. We investigate the tolerability of gefitinib in combined modality therapy in combination with three-dimensional thoracic conformal radiation therapy (3-dimensional TCRT). Stage III patients with a good performance status were treated with induction chemotherapy (carboplatin area under the curve [AUC] of 5, irinotecan 100 mg/m(2), and paclitaxel 175 mg/m(2) days 1 and 22) with pegfilgrastim support followed by concurrent chemotherapy (carboplatin AUC 2, and paclitaxel 45 mg/m(2) weekly) and gefitinib 250 mg daily beginning on day 43 with 3-dimensional TCRT to 74 Gy. Between March 2004 and January 2006, 23 patients received treatment on the trial: median age 62 years (range 44-82), 52% female, 61% stage IIIA, 61% performance status 0, 17% > or =5% weight loss, and 91% underwent positron emission tomography staging. Induction chemotherapy with pegfilgrastim support was well tolerated and active (partial response rate, 24%; stable disease, 76%; and early progression, 0%). Twenty-one patients initiated the concurrent chemoradiation, and 20 patients completed therapy to 74 Gy. The primary toxicities of concurrent chemoradiation were grade 3 esophagitis (19.5%) and cardiac arrhythmia (atrial fibrillation) (9.5%). The median progression-free survival and overall survival were 9 months (95% confidence intervals [CI]: 7-13 months) and 16 months (95% CI: 10-20 months), respectively. Treatment with induction chemotherapy and gefitinib concurrent with 3-dimensional TCRT has an acceptable toxicity and tolerability, but the survival results were disappointing.

Lung transplantation is now routinely performed for a wide range of end-stage cardiopulmonary disorders. Despite overcoming the problems associated with early acute rejection, chronic rejection (CR) in the form of obliterative bronchiolitis has emerged as the primary cause of late graft loss. The mechanisms involved in the development of CR of lung allografts are poorly understood, and no effective therapy is currently available. To better understand the pathological events associated with CR and tolerance, we examined two models of lung allograft rejection established in our laboratory. First, we exchanged left lung allografts between moderately histoincompatible inbred rat strains (WKY-->F344: n = 42 and F344-->WKY: n = 40). The WKY-->F344 model was previously shown to develop spontaneous tolerance, while the converse model (F344-->WKY) showed persistent acute rejection. The purpose of this investigation was to assess histopathological changes associated with long-term grafts left in place up to 140 days after transplant. To confirm that tolerance had developed, skin-grafting experiments were performed. Five skin grafts from each strain were placed on lung allograft recipients on day 35 after transplant and skin allograft survival was assessed and compared with controls. Acute rejection (AR) was graded histologically (stage O-IV) and the pathologic intensity of inflammation and CR were graded (0-4: 0 = 0%, 1 = 1-25%, 2 = 26-50%, 3 = 51-75%, and 4 = 76-100%) on percentage of involvement with the following categories being examined: (a) lymphocytic infiltration (perivascular, peribronchial, and peribronchiolar) and (b) vasculitis, edema, hemorrhage, and necrosis. Finally, chronic rejection was diagnosed by the presence of intimal hyperplasia, interstitial fibrosis, peribronchiolar fibrosis, bronchiolitis obliterans, and bronchiectasis. The WKY-->F344 animals showed progressive AR (stage III, day 21). Thereafter, the AR subsided spontaneously and was stage 0 on day

The purpose of the present study was to retrospectively evaluate impact of pre-treatment skeletal muscle mass (SMM) on overall survival and non-lung cancer mortality after stereotactic body radiotherapy (SBRT) for patients with stage I non-small cell lung cancer (NSCLC). One-hundred and eighty-six patients whose abdominal CT before the treatment was available were enrolled into this study. The patients were divided into two groups of SMM according to gender-specific thresholds for unilateral psoas area. Operability was judged by the treating physician or thoracic surgeon after discussion in a multi-disciplinary tumor board. Patients with low SMM tended to be elderly and underweight in body mass index compared with the high SMM. Overall survival in patients with the low SMM tended to be worse than that in the high SMM (41.1% and 55.9% at 5 years, P = 0.115). Cumulative incidence of non-lung cancer death was significantly worse in the low SMM (31.3% at 5 years compared with 9.7% in the high SMM, P = 0.006). Multivariate analysis identified SMM and operability as significant factors for non-lung cancer mortality. Impact of SMM on lung cancer death was not significant. No difference in rate of severe treatment-related toxicity was observed between the SMM groups. Low SMM is a significant risk factor for non-lung cancer death, which might lead to worse overall survival, after SBRT for stage I NSCLC. However, the low SMM does not increase lung cancer death or severe treatment-related toxicity. Copyright © 2018 Elsevier Inc. All rights reserved.

This study aimed to investigate the outcome for stage II and III rectal cancer patients compared to stage II and III colonic cancer patients with regard to 5-year cause-specific survival (CSS), overall survival, and local and combined recurrence rates over time. This prospective cohort study identified 3,355 consecutive patients with adenocarcinoma of the colon or rectum and treated in our colorectal unit between 1981 and 2011, for investigation. The study was restricted to International Union Against Cancer (UICC) stages II and III. Postoperative mortality and histological incomplete resection were excluded, which left 995 patients with colonic cancer and 726 patients with rectal cancer for further analysis. Five-year CSS rates improved for colonic cancer from 65.0% for patients treated between 1981 and 1986 to 88.1% for patients treated between 2007 and 2011. For rectal cancer patients, the respective 5-year CSS rates improved from 53.4% in the first observation period to 89.8% in the second one. The local recurrence rate for rectal cancer dropped from 34.2% in the years 1981-1986 to 2.1% in the years 2007-2011. In the last decade of observation, prognosis for rectal cancer was equal to that for colon cancer (CSS 88.6 vs. 86.7%, p = 0.409). Survival of patients with colon and rectal cancer has continued to improve over the last three decades. After major changes in treatment strategy including introduction of total mesorectal excision and neoadjuvant (radio)chemotherapy, prognosis for stage II and III rectal cancer is at least as good as for stage II and III colonic cancer.

Full Text Available OBJECTIVES: The proper nodal staging of non-small cell lung cancer is important for choosing the best treatment modality. Although computed tomography remains the first-line imaging test for the primary staging of lung cancer, its limitations for mediastinum nodal staging are well known. The aim of this study is to evaluate the accuracy of hybrid single-photon emission computed tomography and computed tomography using 99mTc-sestamibi in the nodal staging of patients with non-small cell lung cancer and to identify potential candidates for surgical treatment. METHODS: Prospective data were collected for 41 patients from December 2006 to February 2009. The patients underwent chest computed tomography and single-photon emission computed tomography/computed tomography examinations with 99mTc-sestamibi within a 30-day time period before surgery. Single-photon emission computed tomography/computed tomography was considered positive when there was focal uptake of sestamibi in the mediastinum, and computed tomography scan when there was lymph nodes larger than 10 mm in short axis. The results of single-photon emission computed tomography and computed tomography were correlated with pathology findings after surgery. RESULTS: Single-photon emission computed tomography/computed tomography correctly identified six out of 19 cases involving hilar lymph nodes and one out of seven cases involving nodal metastases in the mediastinum. The sensitivity, specificity, positive predictive value, and negative predictive value for 99mTc-sestamibi single-photon emission computed tomography/computed tomography in the hilum assessment were 31.6%, 95.5%, 85.7%, and 61.8%, respectively. The same values for the mediastinum were 14.3%, 97.1%, 50%, and 84.6%, respectively. For the hilar and mediastinal lymph nodes, chest tomography showed sensitivity values of 47.4% and 57.1%, specificity values of 95.5% and 91.2%, positive predictive values of 90% and 57.1% and negative

During mammalian lung development, the morphological transition from respiratory tree branching morphogenesis to a predominantly saccular architecture, capable of air-breathing at birth, is dependent on physical forces as well as molecular signaling by a range of transcription factors including the cAMP response element binding protein 1 (Creb1). Creb1−/− mutant mice exhibit complete neonatal lethality consistent with a lack of lung maturation beyond the branching phase. To further define its role in the developing mouse lung, we deleted Creb1 separately in the respiratory epithelium and mesenchyme. Surprisingly, we found no evidence of a morphological lung defect nor compromised neonatal survival in either conditional Creb1 mutant. Interestingly however, loss of mesenchymal Creb1 on a genetic background lacking the related Crem protein showed normal lung development but poor neonatal survival. To investigate the underlying requirement for Creb1 for normal lung development, Creb1−/− mice were re-examined for defects in both respiratory muscles and glucocorticoid hormone signaling, which are also required for late stage lung maturation. However, these systems appeared normal in Creb1−/− mice. Together our results suggest that the requirement of Creb1 for normal mammalian lung morphogenesis is not dependent upon its expression in lung epithelium or mesenchyme, nor its role in musculoskeletal development.

Aim The aim of this study is to investigate the possibilities of non-invasive diagnostic imaging methods, positron emission tomography/computed tomography (PET/CT) and CT, in clinical N staging of non-small cell lung cancer (NSCLC). Methods Retrospective clinical study included 50 patients with diagnosed NSCLC who have undergone PET/CT for the purpose of disease staging. The International association for the study of lung cancer (IASLC) nodal mapping system was used for analysis of nodal disease. Data regarding CT N-staging and PET/CT Nstaging were recorded. Two methods were compared using χ2 test and Spearman rank correlation coefficient. Results Statistical analysis showed that although there were some differences in determining the N stage between CT and PET/CT, these methods were in significant correlation. CT and PET/CT findings established the same N stage in 74% of the patients. In five patients based on PET/CT findings the staging was changed from operable to inoperable, while in four patients staging was changed from inoperable to operable. Conclusion PET/CT and CT are noninvasive methods that can be reliably used for N staging of NSCLC. Copyright© by the Medical Assotiation of Zenica-Doboj Canton.

Full Text Available O6-methylguanine-DNA methyltransferase (MGMT methylation status has not been extensively investigated in duodenal adenocarcinoma (DA. The aim of this study was to evaluate the MGMT methylation status and examine its possible prognostic value in patients with stage III DA.Demographics, tumor characteristics and survival were available for 64 patients with stage III DA. MGMT methylation was detected by using MethyLight. A Cox proportional hazard model was built to predict survival, adjusted for clinicopathological characteristics and tumor molecular features, including the CpG island methylator phenotype (CIMP, microsatellite instability (MSI, and KRAS mutations.MGMT methylation was detected in 17 of 64 (26.6% patients, and was not correlated with sex, age, tumor differentiation, CIMP, MSI, or KRAS mutations. MGMT methylation was the only one factor associated with both overall survival (OS and disease-free survival (DFS on both univariate and multivariate analyses. In patients treated with surgery alone, MGMT-methylated group had worse OS and DFS when compared with MGMT-unmethylated group. However, in patients treated with chemotherapy/radiotherapy, outcomes became comparable between the two groups.Our results demonstrate MGMT methylation is a reliable and independent prognostic factor in DAs. Methylation of MGMT is associated with poor prognosis in patients with stage III DAs.

Stereotactic body radiation therapy (SBRT) is a new treatment modality for early stage non-small-cell lung cancer, and has been developed in the United States, the European Union, and Japan. We started a feasibility study of this therapy in July 1998, using a stereotactic body frame. The eligibility criteria for primary lung cancer were: 1) solitary tumor less than 4 cm (T1-3NOM); 2) inoperable, or the patient refused operation; 3) no necessity for oxygen support; 4) performance status equal to or less than 2; 5) the peripheral tumor which dose constraints of mediastinal organs are maintained. A total dose of 48 Gy was delivered in four fractions in 2 weeks in most patients. Lung toxicity was minimal. No grade II toxicities for spinal cord, bronchus, pulmonary artery, or esophagus were observed. The 3 years overall survival for 32 patients with stage IA, and 13 patients with stage IB were 83% and 72%, respectively. Only one local recurrence was observed in a follow-up of 6 1 months. We retrospectively analyzed 241 patients from 13 Japanese institutions. The local recurrence rate was 20% when the biological equivalent dose (BED) was less than 100 Gy, and 6.5% when the BED was over 100 Gy. Overall survival at 3 years was 42% when the BED was less than 100 Gy, and 46% when it was over 100 Gy. In tumors, which received a BED of more than 100 Gy, overall survival at 3 years was 91% for operable patients, and 50% for inoperable patients. Long-term results, in terms of local control, regional recurrence, survival, and complications, are not yet evaluated. However, this treatment modality is highly expected to be a standard treatment for inoperable patients, and it may be an alternative to lobectomy for operative patients. A prospective trial, which is now ongoing, will, answer these questions. (author)

In order to establish the treatment strategies for primary lung cancer patients over 80 years old, we retrospectively analyzed the treatment methods and outcome of 174 patients admitted to our hospital from April 1987 to March 2002. A total of 174 patients were classified into stage I (n=25), stage II (n=7), stage III (n=64) and stage IV (n=78). Although the general condition and nutritional condition of patients over 80 years were comparatively poorer than all patients with primary lung cancer, there was no significant difference. In total, 73 patients were treated with surgical resection (13 patients), radiation (35 patients), chemotherapy (15 patients), and chemo-radiation (10 patients). Although the surgical treatment group predominantly included patients at stage I, there were no significant differences in general or nutritional condition, pulmonary function or arterial blood gas among the four treatment groups. The outcome of surgically treated patients was significantly better (p<0.05), whereas there were no significant differences among the other three groups or between the treated group and untreated groups. Only surgical treatment was evaluated to improve the prognosis of primary lung cancer patients over 80 years when respiratory function was adequate for surgical treatment. (author)

Purpose: The results of Phase I/II data testing β-interferon with radiation therapy in a non-small-cell lung cancer population were promising. Based on these data, the Radiation Therapy Oncology Group (RTOG) initiated a Phase III trial to test the efficacy of β-interferon in poor-risk patients with Stages IIIA and IIIB non-small-cell lung carcinoma. Methods: Between September 1994 and March 1998, 123 patients were accrued to this trial. Enrolled patients were not eligible for other chemoradiation studies within the RTOG. Eligibility criteria included histologically confirmed Stage IIIA or IIIB non-small-cell lung cancer (according to American Joint Committee on Cancer) considered clinically inoperable or unresectable at the time of surgery. Patients were required to have a Karnofsky performance status 50-70 or >70 and at least 5% weight loss over the preceding 3 months. Betaseron (recombinant human interferon beta ser , rHuIFN-β ser ,) was the chosen preparation of β-interferon. The patients randomized to the investigational arm received 16x10 6 IU of Betaseron by i.v. bolus given 3 days a week (Monday-Wednesday) on Weeks 1, 3, and 5. The Betaseron was given 30 minutes before radiation therapy for a total of nine doses. Irradiation was delivered at 2 Gy per fraction, 5 days a week, for a total of 60 Gy over 6 weeks and was identical for both arms. The primary end point of the trial was overall survival with local control as a secondary end point. Toxicities occurring within 90 days of therapy completion were defined as acute. Results: The median follow-up was 4 years (range: 2.5-6 years) for surviving patients. Seventy-six percent of all patients completed β-interferon. Toxicity was the primary reason for noncompliance. Radiotherapy (RT) compliance was excellent in the RT-alone arm, with 94% completing therapy, compared to 82% in the β-interferon arm (p=0.0475). Grade 3 and 4 acute toxicities were higher on the β-interferon arm (p=0.0249). Grade 3 and 4

Lung transplant in end-staged chronic obstructive pulmonary disease (COPD) patients: a concise review.

Science.gov (United States)

Aziz, Fahad; Penupolu, Sudheer; Xu, Xin; He, Jianxing

2010-06-01

Lung transplantation is commonly used for patients with end-stage lung disease. However, there is continuing debate on the optimal operation for patients with chronic obstructive pulmonary disease (COPD) and pulmonary fibrosis. Single-lung transplantation (SLT) provides equivalent short- and medium-term results compared with bilateral lung transplantation (BLT), but long-term survival appears slightly better in BLT recipients (especially in patients with COPD). The number of available organs for lung transplantation also influences the choice of operation. Recent developments suggest that the organ donor shortage is not as severe as previously thought, making BLT a possible alternative for more patients. Among the different complications, re-implantation edema, infection, rejection, and bronchial complications predominate. Chronic rejection, also called obliterative bronchiolitis syndrome, is a later complication which can be observed in about half of the patients. Improvement in graft survival depends greatly in improvement in prevention and management of complications. Despite such complications, graft survival in fibrosis patients is greater than spontaneous survival on the waiting list; idiopathic fibrosis is associated with the highest mortality on the waiting list. Patients should be referred early for the pre-transplantation work-up because individual prognosis is very difficult to predict.

Staging of lung cancer requires an accurate evaluation of the mediastinum. Positron imaging with dual head cameras may be not as sensitive as dedicated PET. Therefore, the purpose of the study was to evaluated the usefulness of F-18 FDG coincidence (CoDe) PET using a dual-head gamma camera in the nodal staging of the lung cancer. CoDe-PET studies were performed in 51 patients with histologically proven non small cell lung cancer. CoDe-PET began 60 minutes after the injection of 111-185 MBq of F-18 FDG. CoDe-PET was performed using a dual-head gamma camera equipped with coincidence detection circuitry (Elscints Varicam, Haifa, lsrael). There was no attenuation correction made and reconstruction was done using a filtered back-projection. Surgery was performed in 49 patients CoDe-PET studies were evaluated visually. Any focal increased uptake was considered abnormal. The nodal stating of CoDe-PET studies were evaluated visually. Any focal increased uptake was considered abnormal. The nodal staging of CoDe-PET and of CT were compared with the nodal stating of surgical (49) and mediastinoscopical (2) pathology. All primary lung lesions were hypermetabolic and easily visualized. Compared with surgical nodal staging as a gold standard, false positives occurred in 13 CoDe PET and 17 CT studies and false negative occurred in 5 CoDe-PET and 4 CT studies. Assessment of lymph node involvement by CoDe-PET depicted a sensitivity of 67%, specificity of 64% and accuracy of 65%. CT revealed a sensitivity of 73%, specificity of 53% and accuracy of 59% in the assessment of lymph node involvement. The detection of primary lesions were 100% but nodal staging was suboptimal for routine clinical use. This is mainly due to limited resolution of our system

To investigate the impact of the proposed International Association for the Study of Lung Cancer (IASLC) tumor, node, metastasis (TNM) system on staging and outcome of non small cell lung cancer (NSCLC). With a total of 501 NSCLC patients with staging according to Union for International Cancer Control (UICC), 6th TNM (TNM-6) were reclassified according to the IASLC proposed TNM staging (TNM-7). The impact of TNM-7 in comparison with TNM-6 was evaluated at three levels: change in substage, staging, and outcome. The outcome measure was to compare the stage-specific overall survival of NSCLC between the two groups of patients. A total of 214 (42.7%) patients had changed TNM staging, and 101 (20.2%) patients had changed stage groupings in TNM-7 compared to TNM-6. Among 100 patients showing changed stage grouping, 72 (14.4%) showed upstage and 29 (5.8%) demonstrated downstage. The TNM-7 system resulted in better separation of survival curves among stage-specific NSCLC than TNM-6 system, especially in separation of stage IIA vs. IIB (p 0.023) and stage IIIB vs. IV (p < 0.001). TNM-7 for lung cancer appears to be superior in defining stage-specific survival groups than TNM-6, especially between stage IIA vs. stage IIB and stage IIIB vs. stage IV.
