    ABSTRACT: To report our institutional experience with five fractions of daily 8-12 Gy stereotactic body radiotherapy (SBRT) for the treatment of oligometastatic cancer to the lung. Thirty-four consecutive patients with oligometastatic cancers to the lung were treated with image-guided SBRT between 2008 and 2011. Patient age ranged from 38 to 81 years. There were 17 males and 17 females. Lung metastases were from the following primary cancer types: colon cancer (n=13 patients), head and neck cancer (n=6), breast cancer (n=4), melanoma (n=4), sarcoma (n=4) and renal cell carcinoma (n=3). The median prescription dose was 50 Gy in five fractions (range, 40-60 Gy) to the isocenter, with the 80% isodose line encompassing the planning target volume (PTV) [defined as gross tumor volume (GTV) + 7-11 mm volumetric expansion]. The follow-up interval ranged from 2.4-54 months, with a median of 16.7 months. The 1-, 2-, and 3-year patient local control (LC) rates for all patients were 93%, 88%, and 80% respectively. The 1-, 2-, and 3-year overall survival (OS) rates were 62%, 44%, and 23% respectively. The 1- and 2-year patient LC rates were 95% and 88% for tumor size 1-2 cm (n=25), and 86% for tumor size 2-3 cm (n=7). The majority (n=4) of local failures occurred within 12 months. No patient experienced local failure after 12 months except for one patient with colon cancer whose tumors progressed locally at 26 months. All five patients with local recurrences had colorectal cancer. Statistical analyses showed that age, gender, previous chemotherapy, previous surgery or radiation had no significant effect on LC rates. No patient was reported to have any symptomatic pneumonitis at any time point. SBRT for oligometastatic disease to the lung using 8-12 Gy daily fractions over five treatments resulted in excellent 1- and 2-year LC rates. Most local failures occurred within the first 12 months, with five local failures associated with colorectal cancer. The treatment is safe using this radiation fractionation schedule with no therapy-related pneumonitis.

    ABSTRACT: Cancer specialists require an understanding of survivors' needs to insure optimal delivery of care. Training programs currently focus on treatment, while survivorship care focuses on time after treatment. Cancer survivorship training represents an education paradigm shift. The Cancer Survivorship Workshop was held at the James P. Wilmot Cancer Center of the University of Rochester in academic year 2011-2012, with six sessions held. Objectives included the following: learning about survivorship from patient, primary care physician, and oncologist perspectives using a curriculum based on survivorship literature; designing treatment summaries (TSs) and survivorship care plans (SCPs) for five malignancies (lung, breast, prostate, colon, and lymphoma); and establishing collaboration between hematology/oncology (HO) and radiation oncology (RO) trainees by working together in teams. Course impact was assessed pre- and post-training using a 13-question survey. Questions were answered using a 10-point scale, with predefined rating for each question. Statistically significant differences in responses to several survey questions were observed comparing pre- and post-course experience. Improvement was noted in comfort discussing survivorship issues with patients (p = 0.001), reported knowledge of survivorship care for five types of cancer (p = 0.002), confidence in ability to explain a SCP (p = 0.001), and comfort discussing late effects of cancer treatment (p = 0.001). Five unique sets of TS and SCPs were completed. This study demonstrates the feasibility of implementing cancer survivorship education into the curriculum of HO and RO training. The project was designed with intension to optimize survivor care through enhanced provider training.

    ABSTRACT: The purpose of this study was to determine whether dynamic susceptibility contrast MR perfusion relative cerebral blood volume (rCBV) correlates with prognosis of World Health Organization (WHO) grade III glial tumors and their different subtypes. Retrospective evaluation of pre-treatment tumor rCBV derived from dynamic susceptibility contrast MR perfusion was performed in 34 patients with histopathologically diagnosed WHO grade III glial tumors (anaplastic astrocytomas (n = 20), oligodendrogliomas (n = 4), and oligoastrocytomas (n = 10)). Progression free survival was correlated with rCBV using Spearman rank analysis. ROC curve analysis was performed to determine the operating point for rCBV in patients with anaplastic astrocytomas dichotomized at the median progression free survival time. For all grade III tumors (n = 34) the mean rCBV was 2.51 with a progression free survival of 705.5 days. The mean rCBV of anaplastic astrocytomas was 2.47 with progression free survival 495.2 days. In contrast, the mean rCBV for oligodendroglial tumors was 2.56 with a progression free survival of 1005.6 days. Although there was no significant correlation between rCBV and progression free survival among all types of grade III gliomas (P = 0.12), among anaplastic astrocytomas there was a significant correlation between pretreatment rCBV and progression free survival with correlation coefficient of -0.51 (P = 0.02). The operating point for rCBV in patients with anaplastic astrocytomas dichotomized at the median progression free survival time (446.5 days) was 2.86 with 78 % accuracy and there was a significant difference between the survival of patients with anaplastic astrocytomas in the dichotomized groups (P = 0.0009). Pre-treatment rCBV may serve as a prognostic imaging biomarker for anaplastic astrocytomas, but not grade III oligodendroglioma tumors.

    ABSTRACT: Increased risks of solid tumors after older radiotherapy strategies for testicular cancer (TC) are well established. Few population-based studies, however, focus on solid cancer risk among survivors of TC managed with nonradiotherapy approaches. We quantified the site-specific risk of solid cancers among testicular nonseminoma patients treated in the modern era of cisplatin-based chemotherapy, without radiotherapy. Standardized incidence ratios (SIRs) for solid tumors were calculated for 12,691 patients with testicular nonseminoma reported to the population-based Surveillance, Epidemiology, and End Results program (1980 to 2008) and treated initially with either chemotherapy (n = 6,013) or surgery (n = 6,678) without radiotherapy. Patients accrued 116,073 person-years of follow-up. Two hundred ten second solid cancers were observed. No increased risk followed surgery alone (SIR, 0.93; 95% CI, 0.76 to 1.14; n = 99 solid cancers), whereas significantly increased 40% excesses (SIR, 1.43; 95% CI, 1.18 to 1.73; n = 111 solid cancers) occurred after chemotherapy. Increased risks of solid cancers after chemotherapy were observed in most follow-up periods (median latency, 12.5 years), including more than 20 years after treatment (SIR, 1.54; 95% CI, 0.96 to 2.33); significantly increased three- to seven-fold risks occurred for cancers of the kidney (SIR, 3.37; 95% CI, 1.79 to 5.77), thyroid (SIR, 4.40; 95% CI, 2.19 to 7.88), and soft tissue (SIR, 7.49; 95% CI, 3.59 to 13.78). To our knowledge, this is the first large population-based series reporting significantly increased risks of solid cancers among patients with testicular nonseminoma treated in the modern era of cisplatin-based chemotherapy. Subsequent analytic studies should focus on the evaluation of dose-response relationships, types of solid cancers, latency patterns, and interactions with other possible factors, including genetic susceptibility.

    ABSTRACT: BACKGROUND: Surgical resection is the standard treatment for liver metastases, although for the majority of patients this is not possible. Stereotactic body radiotherapy (SBRT) is an alternative local-regional therapy. The purpose of this study was to evaluate the results of SBRT for secondary liver tumours from a combined multicentre database. METHODS: Variables from patients treated with SBRT from four Academic Medical Centres were entered into a common database. Local tumour control and 1-year survival rates were calculated. RESULTS: In total, 153 patients (91 women) 59 ± 8.4 years old with 363 metastatic liver lesions were treated with SBRT. The underlying primary tumour arose from gastrointestinal (GI), retroperitoneal and from extra-abdominal primaries in 56%, 8% and 36% of patients, respectively. Metastases, with a gross tumour volume (GTV) of 138.5 ± 126.8 cm3 , were treated with a total radiation dose of 37.5 ± 8.2 Gy in 5 ± 3 fractions. The 1-year overall survival was 51% with an overall local control rate of 62% at a mean follow-up of 25.2 ± 5.9 months. A complete tumour response was observed in 32% of patients. Grade 3-5 adverse events were noted in 3% of patients. CONCLUSION: Secondary liver tumours treated with SBRT had a high rate of local control with a low incidence of adverse events.

    ABSTRACT: Purpose: Few studies have evaluated the risk profile of prostate-specific antigen (PSA)-detected T1cN0M0 prostate cancer, defined as tumors diagnosed by needle biopsy because of elevated PSA levels without other clinical signs of disease. However, some men with stage T1cN0M0 prostate cancer may have high-risk disease (HRD), thus experiencing inferior outcomes as predicted by a risk group stratification model. Methods: We identified men diagnosed with stage T1cN0M0 prostate cancer from 2004 to 2008 reported to the surveillance, epidemiology, and end results (SEER) program. Multivariate logistic regression was used to model the probability of intermediate-risk-disease (IRD) (PSA ≥ 10 ng/ml but <20 ng/ml and/or GS 7), and high-risk-disease (HDR) (PSA ≥ 20 ng/ml, and/or GS ≥ 8), relative to low-risk disease (LRD) (PSA < 10 ng/ml and GS ≤ 6), adjusting for age, race, marital status, median household income, and area of residence. Results: A total of 70,345 men with PSA-detected T1cN0M0 prostate cancer were identified. Of these, 47.6, 35.9, and 16.5% presented with low-, intermediate-, and high-risk disease, respectively. At baseline (50 years of age), risk was higher for black men than for whites for HRD (OR 3.31, 95% CI 2.85-3.84). The ORs for age (per year) for HRD relative to LRD were 1.09 (95% CI 1.09-1.10) for white men, and as 1.06 (95% CI 1.05-1.07) for black men. Further, among a subgroup of men with low PSA (<10 ng/ml) T1cN0M0 prostate cancer, risk was also higher for black man than for white men at baseline (50 years of age) (OR 2.70, 95% CI 2.09-3.48). The ORs for age (per year) for HRD relative to LRD were 1.09 (95% CI 1.09-1.10) for white men, and as 1.06 (95% CI 1.05-1.07) for black men. Conclusion: A substantial proportion of men with PSA-detected prostate cancer as reported to the SEER program had HRD. Black race and older age were associated with a greater likelihood of HRD.

    ABSTRACT: Background The increased risk of gastrointestinal (GI) cancers after Hodgkin's lymphoma (HL) is well established. However, no large population-based study has described the actuarial survival after subsequent GI cancers in HL survivors (HL-GI).Patients and methodsFor 209 patients with HL-GI cancers (105 colon, 35 stomach, 30 pancreas, 21 rectum, and 18 esophagus) and 484 165 patients with first primary GI cancers (GI-1), actuarial survival was compared, accounting for age, gender, race, GI cancer stage, radiation for HL, and other variables.ResultsThough survival of HL patients who developed localized stage colon cancer was similar to that of the GI-1 group, overall survival (OS) of HL patients with regional or distant stage colon cancer was reduced [hazard ratio, (HR) = 1.46, P = 0.01]. The HL survivors with regional or distant stage colon cancer in the transverse segment had an especially high risk of mortality (HR: 2.7, P = 0.001 for OS). For localized stomach cancer, OS was inferior among HL survivors (HR = 3.46, P = 0.006).Conclusions The HL patients who develop GI cancer experience significantly reduced survival compared with patients with a first primary GI cancer. Further research is needed to explain the inferior survival of HL patients and to define selection criteria for cancer screening in HL survivors.

    ABSTRACT: Brain metastases are the most common form of intracranial tumor in adults and an increasingly important cause of morbidity and mortality. Rising incidence is attributed to advanced radiographic imaging and prolonged survival due to improvements in cancer therapy (including systemic therapies) that are not as effective in treating intracranial disease. Standard treatment options for brain metastases include resection, whole-brain radiation therapy (WBRT), stereotactic radiosurgery, or a combination of these modalities. Most patients with brain metastases receive some form of radiation therapy during the course of their illness, and for the majority of them, the prognosis is poor and WBRT remains the standard. However, within this very diverse patient population, subgroups exist in which prolonged survival is possible. In recent years, several randomized controlled trials have clearly demonstrated the efficacy of stereotactic radiosurgery in well-selected patients. This, along with an increased recognition of the late neurocognitive effects of WBRT, has led many to question the role of upfront WBRT in patients with limited intracranial metastases. In this review, we summarize the evolving role of radiotherapy in the management of brain metastases and then discuss the issues related to neurotoxicity from radiation and future areas of investigation.

    ABSTRACT: BACKGROUND: The current study characterizes the overall survival (OS) and cause-specific survival (CSS) of patients with stage I nonsmall cell lung cancer (NSCLC) who were treated with radiotherapy alone, and analyzes the variables potentially affecting survival outcomes. METHODS: A total of 8524 patients with stage I NSCLC (according to the sixth edition of the American Joint Committee on Cancer staging manual) who were diagnosed between 1988 and 2008 were retrospectively analyzed using the population-based Surveillance, Epidemiology, and End Results database. Cox regression analysis was used to calculate hazard ratios (HR) from multivariate analyses. RESULTS: The 1-year, 2-year, and 5-year OS rates were 62%, 37%, and 11%, respectively; the corresponding lung cancer CSS survival rates were 68%, 45%, and 20%, respectively. Approximately 77% of deaths were from lung cancer (5292 of 6891 total deaths). Cardiac (n = 477 deaths) and pulmonary (other than lung cancer deaths; n = 475 deaths) deaths accounted for 14% of deaths. From Cox proportional hazards analyses, male sex (HR, 1.2) and squamous cell carcinoma histology (HR, > 1.1) were found to be significantly (P < .0001) adverse prognostic factors for both OS and lung cancer CSS. A more recent calendar year of diagnosis was associated with significantly (P < .0001) improved OS (HR, 0.84 per decade) and lung cancer CSS. This trend was also significant (P < 0.0001) when restricting analyses to those patients with tumors measuring ≤ 5 cm (n = 5402 patients). T1 classification (vs T2 or T unknown) and smaller tumor size were found to be significantly (P < .0001) favorable factors. CONCLUSIONS: From a population-based registry analysis of patients with stage I NSCLC, significant (albeit modest) improvements in survival in more recent years were appreciated, which likely reflect technologic advances in the diagnosis of, staging of, and radiotherapy for NSCLC.

    ABSTRACT: BACKGROUND: Patients with head and neck squamous cell cancer (HNSCC) are at risk of developing second primary lung cancer (SPLC). METHODS: Among 61,883 patients with HNSCC from the Surveillance, Epidemiology and End Results (SEER) database, 4522 developed SPLC (any histology) ≥2 months after HNSCC. We correlated risk with demographic and tumor-related parameters. RESULTS: The risk of SPLC after HNSCC was 5.8%, 11.4%, and 16.4% at 5, 10, and 15 years, respectively. From Cox regression, significantly adverse (p < .0001) risk factors for SPLC included: regional versus localized HNSCC stage (hazard ratio [HR] = 1.16), hypopharyngeal or supraglottic laryngeal site (HR = 1.57), increased age (HR = 1.26/decade), black race (HR = 1.27), and male sex (HR = 1.26). Glottic (HR = 0.75) and tonsillar or oral cavity sites (HR = 0.80) were associated with significantly (p < .0001) lower risks of SPLC. CONCLUSION: From population-based actuarial analyses, HNSCCs with more aggressive clinicopathologic features were more apt to develop SPLC, suggestive of similar environmental and/or host factors for these cancers. © 2012 Wiley Periodicals, Inc.

    ABSTRACT: Patients successfully treated for Hodgkin's lymphoma (HL) are at known risk for subsequent malignancies, the most common of which is lung cancer. To date, no population-based study has analyzed prognostic variables for overall survival (OS) among HL survivors who developed non-small cell lung cancer (NSCLC). For 187 HL patients who developed NSCLC (among 22,648 HL survivors), we examined the impact of the following variables on OS after NSCLC diagnosis: gender, race, sociodemographic status (based upon county of residence), calendar year and age at NSCLC diagnosis, NSCLC histology and grade, HL stage and subtype, radiation for HL and latency between HL and NSCLC. Patients were grouped by NSCLC stage as follows: localized, regional or distant. All patients were reported to the population-based Surveillance, Epidemiology, and End Results program. For those variables significant on univariate analyses, hazard ratios (HR) were derived from Cox proportional hazards model. Sociodemogaphic status, gender and latency between NSCLC and HL did not significantly affect OS of any NSCLC stage group. For patients with localized NSCLC, a history of mixed celluarlity HL was associated with a 3-fold improved OS (P=0.006). For patients with regional NSCLC, prior radiotherapy for HL was associated with a 2-fold worse OS (P=0.025). A history of mixed cellularity HL subtype and a history of no radiotherapy for HL are favorable prognostic factors among patients who develop NSCLC. Further research into clinicopathologic and treatment-associated variables potentially affecting OS after second primary NSCLC among HL survivors is warranted.

    ABSTRACT: An excess of 100 000 individuals are diagnosed with primary liver tumors every year in USA but less than 20% of those patients are amenable to definitive surgical management due to advanced local disease or comorbidities. Local therapies to arrest tumor growth have limited response and have shown no improvement on patient survival. Stereotactic body radiotherapy (SBRT) has emerged as an alternative local ablative therapy. The purpose of this study was to evaluate the tumor response to SBRT in a combined multicenter database. Patients with advanced hepatocellular carcinoma (HCC, n = 21) or intrahepatic cholangiocarcinoma (ICC, n = 11) treated with SBRT from four Academic Medical Centers were entered into a common database. Statistical analyses were performed for freedom from local progression (FFLP) and patient survival. The overall FFLP for advanced HCC was 63% at a median follow-up of 12.9 months. Median tumor volume decreased from 334.2 to 135 cm(3) (p < 0.004). The median time to local progression was 6.3 months. The 1- and 2-years overall survival rates were 87% and 55%, respectively. Patients with ICC had an overall FFLP of 55.5% at a median follow-up of 7.8 months. The median time to local progression was 4.2 months and the six-month and one-year overall survival rates were 75% and 45%, respectively. The incidence of grade 1-2 toxicities, mostly nausea and fatigue, was 39.5%. Grade 3 and 4 toxicities were present in two and one patients, respectively. Higher rates of FFLP were achieved by SBRT in the treatment of primary liver malignancies with low toxicity.

    ABSTRACT: In this study, we sought to characterize post-therapy MRI changes mimicking progression, which we refer to as "spurious progression" (SP) in children with brain tumors. We analyzed whether SP is associated with particular tumor types or therapeutic modalities. Between 2000 and 2009, we identified 181 consecutive children <21 years of age at our center who were treated for brain tumors and had at least three MRI scans within a year after completing therapy. SP was defined as MRI abnormalities characterized by increase in size, enhancement, edema, or cystic changes within 12 months following therapy, and stabilization or improvement on subsequent imaging. One-hundred forty-one patients with brain tumors were evaluable. Fifty-six (40%) had imaging abnormalities initially suggestive of disease progression; of these, 34 (24%) had true disease progression (TP). The remaining 22 (16%) had SP based on either stability, decrease in enhancement, edema, size, or disappearance of these cystic or non-cystic abnormalities. SP occurred in patients with low grade (n = 20) and high grade lesions (n = 2). Median time to SP was 2.4 months (range, 0.7-8.3 months), with time to stability, decrease, or disappearance at a median of 4 months (range 1.4-7.7 months). Five patients were clinically symptomatic from SP and were treated with steroids, cyst drainage, and/or surgery. Therefore, SP occurs more commonly in children with low grade tumors, but can also occur with high grade brain tumors, regardless of therapeutic approach.

    ABSTRACT: To analyze the long-term survival and tumor control outcomes after stereotactic body radiotherapy (SBRT) for metastases limited in number and extent. We prospectively analyzed the long-term overall survival (OS) and cancer control outcomes of 121 patients with five or fewer clinically detectable metastases, from any primary site, metastatic to one to three organ sites, and treated with SBRT. Freedom from widespread distant metastasis (FFDM) was defined as metastatic disease not amenable to local therapy (i.e., resection or SBRT). Prognostic variables were assessed using log-rank and Cox regression analyses. For breast cancer patients, the median follow-up was 4.5 years (7.1 years for 16 of 39 patients alive at the last follow-up visit). The 2-year OS, FFDM, and local control (LC) rate was 74%, 52%, and 87%, respectively. The 6-year OS, FFDM, and LC rate was 47%, 36%, and 87%, respectively. From the multivariate analyses, the variables of bone metastases (p = .057) and one vs. more than one metastasis (p = .055) were associated with a fourfold and threefold reduced hazard of death, respectively. None of the 17 bone lesions from breast cancer recurred after SBRT vs. 10 of 68 lesions from other organs that recurred (p = .095). For patients with nonbreast cancers, the median follow-up was 1.7 years (7.3 years for 7 of 82 patients alive at the last follow-up visit). The 2-year OS, FFDM, and LC rate was 39%, 28%, and 74%, respectively. The 6-year OS, FFDM, and LC rate was 9%, 13%, and 65%, respectively. For nonbreast cancers, a greater SBRT target volume was significantly adverse for OS (p = .012) and lesion LC (p < .0001). Patients whose metastatic lesions, before SBRT, demonstrated radiographic progression after systemic therapy experienced significantly worse OS compared with patients with stable or regressing disease. Select patients with limited metastases treated with SBRT are long-term survivors. Future research should address the therapeutic benefit of SBRT for these patients.

    ABSTRACT: We sought to determine efficacy, safety, and outcome of stereotactic hypofractionated radiation therapy (SHORT) as a suitable bridging therapy for patients awaiting liver transplantation (LT) for hepatocellular carcinoma (HCC). We also examined histological response to radiation in the resected or explanted livers. Between August 2007 and January 2009, 18 patients with 21 lesions received SHORT. A median total dose of 50 Gy was delivered in 10 fractions. Three patients underwent either chemoembolization (n = 1) or radiofrequency ablation (n = 2) prior to SHORT. Radiographic response was based on computed tomography evaluation at 3 months after SHORT. Histological response as a percentage of tumor necrosis was assessed by a quantitative morphometric method. Six of 18 patients were delisted because of progression (n = 3) or other causes (n = 3). Twelve patients successfully underwent major hepatic resection (n = 1) or LT (n = 11) at a median follow-up of 6.3 months (range, 0.6-11.6 months) after completion of SHORT. No patient developed gastrointestinal toxicity Grade ≥3 or radiation-induced liver disease. Ten patients with 11 lesions were evaluable for pathological response. Two lesions had 100% necrosis, three lesions had ≥50% necrosis, four lesions had ≤50% necrosis, and two lesions had no necrosis. All patients were alive after LT and/or major hepatic resection at a median follow-up of 19.6 months. SHORT is an effective bridging therapy for patients awaiting LT for HCC. It provides excellent in-field control with minimal side effects, helps to downsize or stabilize tumors prior to LT, and achieves good pathological response.

    ABSTRACT: Central nervous system (CNS) lesions that are discovered incidentally when imaging children for problems that were unrelated to the detected lesion pose a dilemma to physicians. Because there are few data on the outcome of such cases, we retrospectively reviewed the clinical course of a group of children followed at our institution with brain lesions found incidentally on neuro-imaging. A database of all children with brain lesions followed at the University of Rochester medical center from 2000 to 2010 was reviewed. Data were obtained regarding presentation, magnetic resonance imaging (MRI) features, treatment, progression-free survival, and overall survival of children with brain lesions found incidentally. Of the 244 children with brain lesions seen over this time period, 21 (8.6%) were found to have incidentally discovered brain lesions. Of these 21 children, 12 (57%) underwent surgical resection of their brain lesions. Ten patients (48%) had symptoms considered to be unassociated with the detected lesion. Lesions were found in the cerebellum (n = 7, 33%), midline (n = 5, 24%), and cerebrum (n = 9, 43%). All lesions were ≤5 cm in diameter. Eight patients (38%) had surgery at presentation, one because of imaging features suspicious for a posterior fossae ependymoma, and the seven others because of location in the posterior fossae or brain stem. Of the remaining 13 patients, five had progression of disease on serial MRI scans: four underwent surgery and the fifth was monitored and remained stable after the initial progression stabilized. Nine of the ten patients (90%) with posterior fossae lesions underwent surgery, while only three of 11 with supratentorial lesions underwent surgery (27%) (P = 0.006). The progression free survival was 94% at 12 months (95% CI 65-99%) and 71% at 24 months (95% CI 39-88%). At a median follow-up of 32 months, the overall survival was 100%. Incidentally detected CNS lesions are usually small. The outcome for children with such lesions is excellent. Close monitoring of these patients with serial MRIs may be a safe alternative to immediate biopsy and/or resection for select patients.

    ABSTRACT: Radiotherapy with its advantage of organ preservation has been used to treat laryngeal cancer (LC) for several decades. However, the impact of radiation on overall survival (OS) in a large population-based study has not been evaluated to date. The authors analyzed all patients who had localized and/or regional glottic and supraglottic cancer in the Surveillance, Epidemiology, and End Results Program by comparing treatment trends and OS for the periods 1988 to 1993, 1994 to 1999, and 2000 to 2006. Kaplan-Meier and logistic regression analyses were conducted to evaluate OS and the influence of patient demographics on treatment received. Among 13,808 patients with LC, radiotherapy use increased over the 3 periods for localized glottic cancer (LGC) (94%, 97%, and 98% during 1988-1993, 1994-1999, and 2000-2006, respectively; P < .001); for regional glottic cancer (RGC) (53%, 66%, and 75%, respectively; P < .001), for localized supraglottic cancer (LSGC) (61%, 83%, and 94%, respectively), and for regional supraglottic cancer (RSGC) (43%, 55%, and 78%, respectively; P < .001). No significant decrease in 5-year OS was observed during the 3 periods (LGC: 73%, 76%, and 78%, respectively; RGC: 57%, 51%, and 56%, respectively; LSGC: 33%, 35%, and 39%, respectively; and RSGC: 36%, 36%, and 43%, respectively). Blacks were significantly less likely to receive radiotherapy than whites (odds ratio: LGC, 0.42; RGC, 0.76; RSGC, 0.68; all P < .05). Those in the lowest tertile of median household income, compared with highest tertile, received radiotherapy less frequently (odds ratio: LGC, 0.42; RGC, 0.57; RSGC, 0.57; all P < .001). The current results indicated that the increased use of radiation with its advantage of speech preservation had no adverse impact on the survival of patients with LC. Black race and low income status had significant, inverse relations with the receipt of radiotherapy.

    ABSTRACT: Standard therapy for metastatic non small cell lung cancer (NSCLC) includes palliative systemic chemotherapy and/or radiotherapy. Recent studies of patients with limited metastases treated with curative-intent stereotactic body radiation therapy (SBRT) have shown encouraging survival. We hypothesized that patients treated with SBRT for limited metastases have comparable outcomes with those treated with curative-intent radiation for Stage III NSCLC. We retrospectively reviewed the records of NSCLC patients treated with curative-intent radiotherapy at the University of Rochester from 2000-2008. We identified 3 groups of patients with NSCLC: stage III, stage IV, and recurrent stage IV (initial stage I-II). All stage IV NSCLC patients treated with SBRT had ≤ 8 lesions. Of 146 patients, 88% had KPS ≥ 80%, 30% had > 5% weight loss, and 95% were smokers. The 5-year OS from date of NSCLC diagnosis for stage III, initial stage IV and recurrent stage IV was 7%, 14%, and 27% respectively. The 5-year OS from date of metastatic diagnosis was significantly (p < 0.00001) superior among those with limited metastases (≤ 8 lesions) versus stage III patients who developed extensive metastases not amenable to SBRT (14% vs. 0%). Stage IV NSCLC is a heterogeneous patient population, with a selected cohort apparently faring better than Stage III patients. Though patients with limited metastases are favorably selected by virtue of more indolent disease and/or less bulky disease burden, perhaps staging these patients differently is appropriate for prognostic and treatment characterization. Aggressive local therapy may be indicated in these patients, though prospective clinical studies are needed.
