    ABSTRACT: Background: The National Lung Screening Trial demonstrated that screening for lung cancer improved overall survival (OS) and reduced lung cancer mortality in the 55- to 74-year-old age group by increasing the proportion of cancers detected at an early stage. Because of the increasing life expectancy of the American population, we investigated whether screening for lung cancer might benefit men and women aged 75-84 years. Materials/Methods: Rates of non-small cell lung cancer (NSCLC) from 2000 to 2009 were calculated in both younger and older age groups using the surveillance epidemiology and end reporting database. OS and lung cancer-specific survival (LCSS) in patients with Stage I NSCLC diagnosed from 2004 to 2009 were analyzed to determine the effects of age and treatment. Results: The per capita incidence of NSCLC decreased in the 55-74 cohort, but increased in the 75-84 cohort over the study period. Crude lung cancer death rates in the two age groups who had no specific treatment were 39.5 and 44.9%, respectively. These rates fell in both age groups when increasingly aggressive treatment was used. Rates of OS and LCSS improved significantly with increasingly aggressive treatment in the 75-84 age group. The survival benefits of increasingly aggressive treatment in 75- to 84-year-old females did not differ from their counterparts in the younger cohort. Conclusion: Screening for lung cancer might be of benefit to individuals at increased risk of lung cancer in the 75-84 age group. The survival benefits of aggressive therapy are similar in females between 55-74 and 75-84 years old.

    ABSTRACT: OBJECTIVE: An increasing proportion of patients with stage I non-small cell lung cancer (NSCLC) is undergoing sublobar resection (L-). However, there is little information about the risks and correlates of local recurrence (LR) after such surgery, especially compared with patients undergoing lobectomy (L+). METHODS: Ninety-three and 318 consecutive patients with stage I NSCLC underwent L- and L+, respectively, from 2000 to 2006. Median follow-up was 34 months. RESULTS: In the L- group, the LR rates at 2, 3, and 5 years were 13%, 24%, and 40%, respectively. The risk of LR was significantly associated with tumor grade, tumor size, and T stage. The crude risk of LR was 33.8% (21 of 62) for patients whose tumors were grade ≥ 2. In the L+ group, the LR rates at 2, 3, and 5 years were 14%, 19%, and 24%, respectively. The risk of LR significantly increased with increasing tumor size, length of hospital stay, and the presence of diabetes. The L- group experienced a significant increase in failure in the bronchial stump/staple line compared with the L+ group (10% vs 3%; P = .04) and nonsignificant trends toward increased ipsilateral hilar and subcarinal failure rates. CONCLUSIONS: Patients with stage I NSCLC who undergo L- have an increased risk of LR compared with patients undergoing L+, particularly when they have tumors grade ≥ 2 or tumor size > 2 cm. If L- is considered, additional local therapy should be considered to reduce this risk of LR, especially with tumors grade ≥ 2 or size > 2 cm.

    ABSTRACT: BACKGROUND: Stereotactic body radiotherapy (SBRT) is an alternative to surgery for clinical stage I non-small cell lung cancer (NSCLC), but comparing its effectiveness is difficult because of differences in patient selection and staging. METHODS: Two databases were combined which contained patients treated from 1999 to 2008 by lobectomy (LR, n = 132), sublobar resection (SLR, n = 48), and SBRT (n = 137) after negative staging. Univariate and multivariate analysis were performed for survival (OS), total recurrence control (TRC comprises local-regional and distant control), and locoregional control (LRC) in our entire population. A matched-pair analysis was also performed that compared surgery and SBRT results. Median follow-up for the entire study population was 25.8 months. RESULTS: On univariate analysis, OS was significantly worse with SBRT and also correlated with histology, the Charlson comorbidity index, tumor size, and aspirin use; TRC correlated only with histology; and no variable significantly correlated with LRC. OS was significantly poorer for SBRT in the matched-pair analysis than for patients treated with surgery, but TRC and LRC were not significantly different between these groups. Multivariate analyses including propensity score as a covariate (controlling for all factors affecting treatment selection) found that OS correlated only with Charlson comorbidity index, and TRC correlated only with tumor grade. LRC correlated only with tumor size with or without propensity score correction. CONCLUSIONS: This retrospective study has demonstrated similar OS, LRC, and TRC with SBRT or surgery after controlling for prognostic and patient selection factors. Randomized clinical trials are needed to better compare the effectiveness of these treatments. Cancer 2013. © 2013 American Cancer Society.

    ABSTRACT: BACKGROUND: Despite growing utilization of accelerated partial breast irradiation using brachytherapy (APBI-Brachy) for elderly breast cancer patients, there are limited data from randomized Phase III trials to support its routine use. This study uses population-based data to examine whether APBI-Brachy results in comparable survival rates compared with whole breast irradiation (WBI). METHODS: A sample of 29,647 female patients diagnosed with nonmetastatic breast cancer in 2002-2007 treated with breast-conserving surgery and radiotherapy was identified in the Surveillance, Epidemiology, and End Results Program-Medicare data set. Log-rank tests, Cox proportional hazards models, instrumental variable analysis, and subgroup analysis were used to study the comparative effectiveness of APBI-Brachy and WBI. RESULTS: During a median followup of 3.6 and 4.8 years, 123 (7.7%) and 3438 (13.6%) patients died after APBI-Brachy and WBI, respectively. Recurrence-free survival (p = 0.9711) and overall survival rates (p = 0.0551) did not differ significantly between the two radiation modalities. After accounting for tumor characteristics, patient characteristics, community factors, and comorbidities, the recurrence-free survival (hazard ratio, 1.05; 95% confidence interval, 0.90-1.23; p = 0.5125) and overall survival (hazard ratio, 0.87; 95% confidence interval, 0.72-1.04; p = 0.1332) rates were still not significantly different between patients treated with APBI-Brachy and WBI. CONCLUSION: Partial breast brachytherapy and WBI resulted in similar recurrence-free and overall survival rates in this cohort of elderly breast cancer patients, even after adjustment for the more favorable characteristics of patients in the former group. These findings will need to be confirmed by the randomized trials comparing these modalities.

    ABSTRACT: Recent data suggest that axillary lymph node dissection (ALND) may be unnecessary for patients with positive sentinel lymph node biopsy (SLNB) receiving whole-breast irradiation (ACOSOG Z0011). The purpose of this study was to use decision analysis with simulated patients to determine subgroups with positive SLNB who may still benefit from ALND. We performed a decision analysis simulating axillary recurrence (ALR) risk, lymphedema, and quality of life following breast-conserving surgery (BCS) with positive SLNB and either completion ALND and whole-breast radiation (ALND + BRT) or breast radiation (BRT) alone. Simulated patients were divided into two risk groups based on the likelihood of disease in non-sentinel axillary nodes after positive SLNB: those with risk 30-60 % ("high-risk") and those with risk under 30 % ("low-risk," similar to average Z0011 patients). In simulated patients aged 55, BRT alone resulted in 1 month of additional QALE in the low-risk group versus ALND + BRT, while ALND + BRT resulted in 9.7 months of additional QALE in the high-risk group versus BRT alone. Overall survival was similar at 5 years in this simulation with either treatment in both groups, but ALND + BRT was superior to BRT alone at 20 years in the high-risk group (42 vs. 38 %). In the low-risk group, BRT alone is preferable unless ALR risk with BRT is greater than 1.6 % or lymphedema risk with ALND is under 10 %. Patients eligible for Z0011 but at a higher risk of residual nodal disease following BCS and positive SLNB may benefit from ALND + BRT, rather than BRT alone.

    ABSTRACT: External beam accelerated partial breast irradiation (APBI) is an increasingly popular technique for treatment of patients with early stage breast cancer following breast-conserving surgery. Here we present 5-year results of a prospective trial. From October 2003 through November 2005, 98 evaluable patients with stage I breast cancer were enrolled in the first dose step (32 Gy delivered in 8 twice-daily fractions) of a prospective, multi-institutional, dose escalation clinical trial of 3-dimensional conformal external beam APBI (3D-APBI). Median age was 61 years; median tumor size was 0.8 cm; 89% of tumors were estrogen receptor positive; 10% had a triple-negative phenotype; and 1% had a HER-2-positive subtype. Median follow-up was 71 months (range, 2-88 months; interquartile range, 64-75 months). Five patients developed ipsilateral breast tumor recurrence (IBTR), for a 5-year actuarial IBTR rate of 5% (95% confidence interval [CI], 1%-10%). Three of these cases occurred in patients with triple-negative disease and 2 in non-triple-negative patients, for 5-year actuarial IBTR rates of 33% (95% CI, 0%-57%) and 2% (95% CI, 0%-6%; P<.0001), respectively. On multivariable analysis, triple-negative phenotype was the only predictor of IBTR, with borderline statistical significance after adjusting for tumor grade (P=.0537). Overall outcomes were excellent, particularly for patients with estrogen receptor-positive disease. Patients in this study with triple-negative breast cancer had a significantly higher IBTR rate than patients with other receptor phenotypes when treated with 3D-APBI. Larger, prospective 3D-APBI clinical trials should continue to evaluate the effect of hormone receptor phenotype on IBTR rates.

    ABSTRACT: We review the evidence for optimal surgical management and adjuvant therapy for patients with stages I and II non-small cell lung cancer (NSCLC) along with factors associated with increased risks of recurrence. Based on the current evidence, we recommend optimal use of mediastinal lymph node dissection, adjuvant chemotherapy, and post-operative radiation therapy, and make suggestions for areas to explore in future prospective randomized clinical trials.

    ABSTRACT: The present study was performed to evaluate the significance of biologic subtype and 21-gene recurrence score relative to local recurrence and local-regional recurrence after breast conservation treatment with radiation. Eastern Cooperative Oncology Group E2197 was a prospective randomized clinical trial that compared two adjuvant systemic chemotherapy regimens for patients with operable breast carcinoma with 1-3 positive lymph nodes or negative lymph nodes with tumor size >1.0 cm. The study population was a subset of 388 patients with known 21-gene recurrence score and treated with breast conservation surgery, systemic chemotherapy, and definitive radiation treatment. Median follow-up was 9.7 years (range = 3.7-11.6 years). The 10-year rates of local recurrence and local-regional recurrence were 5.4 % and 6.6 %, respectively. Neither biologic subtype nor 21-gene Recurrence Score was associated with local recurrence or local-regional recurrence on univariate or multivariate analyses (all P ≥ 0.12). The 10-year rates of local recurrence were 4.9 % for hormone receptor positive, HER2-negative tumors, 6.0 % for triple negative tumors, and 6.4 % for HER2-positive tumors (P = 0.76), and the 10-year rates of local-regional recurrence were 6.3, 6.9, and 7.2 %, respectively (P = 0.79). For hormone receptor-positive tumors, the 10-year rates of local recurrence were 3.2, 2.9, and 10.1 % for low, intermediate, and high 21-gene recurrence score, respectively (P = 0.17), and the 10-year rates of local-regional recurrence were 3.8, 5.1, and 12.0 %, respectively (P = 0.12). For hormone receptor-positive tumors, the 21-gene recurrence score evaluated as a continuous variable was significant for local-regional recurrence (hazard ratio 2.66; P = 0.03). The 10-year rates of local recurrence and local-regional recurrence were reasonably low in all subsets of patients. Neither biologic subtype nor 21-gene recurrence score should preclude breast conservation treatment with radiation.

    ABSTRACT: To examine the local and distant recurrence rates and patterns of failure in patients undergoing potentially curative resection of N1 non-small-cell lung cancer. The study included 60 consecutive unirradiated patients treated from 2000 to 2006. Median follow-up was 30 months. Failure rates were calculated by the Kaplan-Meier method. A univariate Cox proportional hazard model was used to assess factors associated with recurrence. Local and distant failure rates (as the first site of failure) at 2, 3, and 5 years were 33%, 33%, and 46%; and 26%, 26%, and 32%, respectively. The most common site of local failure was in the mediastinum; 12 of 18 local recurrences would have been included within proposed postoperative radiotherapy fields. Patients who received chemotherapy were found to be at increased risk of local failure, whereas those who underwent pneumonectomy or who had more positive nodes had significantly increased risks of distant failure. Patients with resected non-small-cell lung cancer who have N1 disease are at substantial risk of local recurrence as the first site of relapse, which is greater than the risk of distant failure. The role of postoperative radiotherapy in such patients should be revisited in the era of adjuvant chemotherapy.

    ABSTRACT: In patients with early-stage breast cancer treated with breast-conserving surgery, randomized trials have found little difference in local control and survival outcomes between patients treated with conventionally fractionated (CF-) whole breast irradiation (WBI) and those receiving hypofractionated (HF)-WBI. However, it remains controversial whether these results apply to all subgroups of patients. We therefore developed an evidence-based guideline to provide direction for clinical practice. A task force authorized by the American Society for Radiation Oncology weighed evidence from a systematic literature review and produced the recommendations contained herein. The majority of patients in randomized trials were aged 50 years or older, had disease Stage pT1-2 pN0, did not receive chemotherapy, and were treated with a radiation dose homogeneity within ±7% in the central axis plane. Such patients experienced equivalent outcomes with either HF-WBI or CF-WBI. Patients not meeting these criteria were relatively underrepresented, and few of the trials reported subgroup analyses. For patients not receiving a radiation boost, the task force favored a dose schedule of 42.5 Gy in 16 fractions when HF-WBI is planned. The task force also recommended that the heart should be excluded from the primary treatment fields (when HF-WBI is used) due to lingering uncertainty regarding late effects of HF-WBI on cardiac function. The task force could not agree on the appropriateness of a tumor bed boost in patients treated with HF-WBI. Data were sufficient to support the use of HF-WBI for patients with early-stage breast cancer who met all the aforementioned criteria. For other patients, the task force could not reach agreement either for or against the use of HF-WBI, which nevertheless should not be interpreted as a contraindication to its use.

    ABSTRACT: We recently demonstrated that diabetes mellitus was an independent risk factor for local recurrence (LR) for patients undergoing resection of non-small cell lung cancer (NSCLC). This investigation was performed to confirm or refute this finding in a different patient cohort. Patients were eligible if they did not have a second primary cancer within 5 years of the original diagnosis, had at least 3-month follow-up, and did not receive radiotherapy. There were 373 and 168 patients in the original (P1) and confirmatory (P2) cohorts, respectively, with 66 and 30 patients with diabetes. The median follow-up was 33 months (range, 3-98 months). Diabetes was an independent risk factor for LR in a Cox model in both the P2 (p=0.05, hazard ratio [HR] 2.15) and P1 (p=0.008, HR 1.90) cohorts, separately from BMI, glucose control, and the presence of the metabolic syndrome. The rates of LR in the patients with diabetes after combining the cohorts at 2, 3, and 5 years were 23%, 33%, and 56%, respectively; these rates were 15%, 19%, and 26% in non-diabetics. In multivariate Cox regression and competing risk analysis of the combined cohorts, the HRs for LR in patients with diabetes exceeded those of more established risk factors for LR including a 1-cm increase in tumor size and lymphovascular invasion. Diabetes was confirmed to be an independent predictor of the risk of LR following resection of NSCLC.

    ABSTRACT: Stage I or II small cell lung cancer is rare. We evaluated the contemporary incidence of early-stage small cell lung cancer and defined its optimal local therapy. We analyzed the incidence, treatment patterns, and outcomes of 2214 patients with early-stage small cell lung cancer (1690 with stage I and 524 with stage II) identified from the Surveillance, Epidemiology, and End Results database from 1988 to 2005. Early-stage small cell lung cancer constituted a stable proportion of all small cell lung cancers (3%-5%), lung cancers (0.10%-0.17%), and stage I lung cancers (1%-1.5%) until 2003 but, by 2005, increased significantly to 7%, 0.29%, and 2.2%, respectively (P < .0001). Surgery for early-stage small cell lung cancer peaked at 47% in 1990 but declined to 16% by 2005. Patients treated with lobectomy or greater resections (lobe) without radiotherapy had longer median survival (50 months) than those treated with sublobar resections (sublobe) without radiotherapy (30 months, P = .006) or those treated with radiotherapy alone (20 months, P < .0001). Patients undergoing sublobe without radiotherapy also demonstrated superior survival than patients receiving radiotherapy alone (P = .002). The use or omission of radiotherapy made no difference after limited resection (30 vs 28 months, P = .6). Multivariable analysis found survival independently related to age, year of diagnosis, tumor size, stage, and treatment (lobe vs sublobe vs radiotherapy alone). Surgery is an underused modality in the management of early-stage small cell lung cancer. Lobectomy provides optimal local control and leads to superior survival. Although sublobar resection proved inferior to lobectomy, it conferred a survival advantage superior to radiotherapy alone. The addition of radiotherapy to resection provided no additional benefit.

    ABSTRACT: There are few long-term studies of how the sequencing of postmastectomy radiotherapy (PMRT) and breast reconstruction (BR) affects the time to development of complications or patient satisfaction with BR. We therefore studied this issue. One hundred thirteen women who underwent BR at Beth Israel Deaconess Medical Center (Boston, MA) from 1999-2006 and also received PMRT were included. Complications requiring surgery were categorized as early (within 90 days of BR) or late. The median length of follow-up after BR was 46.5 months. Patients' general and esthetic satisfaction was assessed with a validated questionnaire. Complications occurred among 32% of 57 women receiving PMRT before BR and 44% of 57 patients having BR before PMRT (p = 0.176). Early complications were more frequent in patients who had PMRT first (18%) than for those with BR first (11%) (p = 0.210); conversely, late complication rates in the two groups were 14% and 33%, respectively (p = 0.009). General satisfaction was comparable between the PMRT-first and BR-first groups (68% and 68%, respectively; p = 0.995); esthetic satisfaction rates were also similar (50% and 62%, respectively; p = 0.238). The sequencing of PMRT and BR did not have a substantial impact on the total risk of complications or patients' general and esthetic satisfaction. However, early complications tended to develop in patients having PMRT first, whereas patients having BR first had a higher risk of late complications. Additional study of the effects of sequencing of PMRT on particular types of reconstructions may help devise strategies for reducing these risks.

    ABSTRACT: To compare the presenting and prognostic characteristics of patients with large cell neuroendocrine lung cancer (LCNELC) with those of patients with small cell lung cancer (SCLC) or other large cell carcinomas (OLCs) and to compare overall survival (OS) and lung cancer-specific survival (LCSS) rates for patients undergoing definitive resection without radiotherapy (S-NoRT). The Surveillance Epidemiology and End Results Database-17 from 2001 to 2007 was used. Differences between population characteristics were compared using χ(2) and Wilcoxon tests. The log-rank test and Cox models were used to compare differences in OS and LCSS. There were 1211 patients with LCNELC (324 in the S-NoRT group), 8295 patients with OLC (1120 S-NoRT), and 35,304 patients with SCLC (355 S-NoRT). The proportion of all large cell carcinomas constituted by LCNELC increased from 8 to 21% during the study period; and the proportion of patients with large cell carcinoma undergoing S-NoRT increased from 16 to 26%. Presenting and histopathologic characteristics and treatment factors of patients undergoing S-NoRT for patients with LCNELC were more similar to those of patients with OLC than to those with SCLC. OS and LCSS rates for patients with LCNELC undergoing resection without radiation were similar to those of patients with OLC and better than those for patients with SCLC, but the differences were not statistically significant on multivariate analysis. The clinical, histopathologic, and biologic features of LCNELC are more similar to OLC than to SCLC. Therefore, LCNELC should continue to be classified and treated as a large cell carcinoma.

    ABSTRACT: Breast-conserving therapy is a successful, well-studied, and scientifically validated treatment of early-stage breast carcinoma. This approach has enormously improved the quality of life and cosmetic outcome for appropriately selected and treated patients while achieving the same long-term survival rates as mastectomy. This article reviews the evidence showing the importance of achieving initial local control to maximize breast cancer-specific survival rates, the impact of systemic therapy on the local control rates achieved with breast-conserving therapy, the integration of chemotherapy with radiation therapy, and the role of breast magnetic resonance imaging in breast-conserving therapy.
