Equivalent survival between lobectomy and segmentectomy for clinical stage IA lung cancer.
This study compared the effectiveness of lobectomy and segmentectomy for treatment of clinical stage IA (T1N0) lung cancer patients. The Society of Thoracic Surgeons General Thoracic Surgery Database was linked to Medicare data in 14,286 lung cancer patients who underwent segmentectomy (n = 1654) or lobectomy (n = 12,632) from 2002 to 2015. Survival rates were found to be similar.

Depressive symptoms do not discriminate: racial and economic influences between time-varying depressive symptoms and mortality among REGARDS participants.
This study examined whether time-varying depressive symptoms (TVDS) predict mortality and if racial and income differences moderate the association in a large cohort. The cohort from the REGARDS study was used to look at that determination. The REGARDS study used community-dwelling U.S. adults aged 45 years or older. They found that there was similar and statistically significant differences with white, black, and low-income ($35,000 or less) participants for the association between TVDS and mortality. High-income participants were found to have a lower hazard.

Improvements in sepsis-associated mortality in hospitalized patients with cancer versus those without cancer. a 12-year analysis using clinical data.
The goal of this study was to assess trends in sepsis-associated mortality in hospitalized patients with and without cancer using objective clinical criteria to identify sepsis and detailed clinical data to adjust for severity of illness. Findings showed that sepsis-associated mortality rates declined significantly over a 12-year period in patients with cancer, but not in patients without cancer. Potential explanations include advances in the management of cancer and/or better sepsis treatments specifically in patients with cancer.

Continuation of annual screening mammography and breast cancer mortality in women older than 70 years.
This study examined whether discontinuing annual mammography screening in women older than 70 years results in an increased 8-year breast cancer mortality. The researchers used data from the Medicare program and looked at over 1 million beneficiaries aged 70 to 84 who had no previous breast cancer diagnosis, and who underwent screening mammography from 2000 to 20008. The 8-year risk difference for women aged 70 to 74 years was -1.0 death per 1000 women and for women aged 75 to 84 years it was 0.07. Neither of these show substantial reductions in 8-year breast cancer mortality compared with stopping screening.

Increased incidence and mortality of gastric cancer in immigrant populations from high to low regions of incidence: a systematic review and meta-analysis.
Gastric cancer is the leading cause of infection-related cancer death and the third-leading cause of cancer death worldwide. The effect of immigration on gastric cancer risk is not well-defined but might be helpful for screening or surveillance endeavors. In this study, the authors performed a systematic review and meta-analysis to define the risk of gastric cancer in immigrants from high-incidence regions to low-incidence regions (including Western Europe, Australia, Brazil, Canada, Israel, and the United States).

Association between power morcellation and mortality in women with unexpected uterine cancer undergoing hysterectomy or myomectomy.
Despite concerns that power morcellation may adversely affect prognosis of patients with occult uterine cancer, empirical evidence has been limited and inconclusive. In this study, the investigators aimed to determine whether uncontained power morcellation at the time of hysterectomy or myomectomy was associated with increased mortality risk in women with occult uterine cancer.

Type and case volume of health care facility influences survival and surgery selection in cases with early-stage non-small cell lung cancer.
With the expansion of non-small cell lung cancer (NSCLC) screening methods, the percentage of cases with early-stage NSCLC is anticipated to increase. Yet it remains unclear how the type and case volume of the health care facility at which treatment occurs may affect surgery selection and overall survival for cases with early-stage NSCLC. In this study, the investigators examine how type and case volume of health care facility influenced survival and surgery selection in cases with early-stage non-small cell lung cancer.

Is breast-conserving therapy appropriate for male breast cancer patients? A national cancer database analysis.
The purpose of this study was to compare overall survival rates among male breast cancer patients who underwent breast-conserving therapy (BCT) versus mastectomy. A retrospective analysis identified 8445 stage I-II male breast cancer patients from the National Cancer Database and grouped them according to surgical and radiation therapy (RT). Most of the patients underwent total mastectomy, while 18.2% underwent BCT, 12.4% underwent total mastectomy with RT, and 8.2% underwent partial mastectomy alone. Partial mastectomy alone, total mastectomy alone, and total mastectomy with RT were associated with worse overall survival rates compared with BCT. The authors conclude that BCT is associated with greater survival, but the underlying mechanisms of this association warrant further study.

Call for improved design and reporting in soft tissue sarcoma studies: a systematic review and meta-analysis of chemotherapy and survival outcomes in resectable STS.
Researchers completed a meta-analysis of chemotherapy in localized STS, assessing OS, PFS, and local and distant recurrence. They found no benefit of chemotherapy over locoregional therapy alone for all-comers or site-specific STS. Recommendations to improve outcome reporting and quality indices are suggested.

Impact of concurrent medication use on pancreatic cancer survival-SEER-Medicare analysis.
Researchers examined the association of several medication classes on pancreatic cancer survival, using data from the Surveillance, Epidemiology, and End Results-Medicare database. They found that the use of beta-blockers, heparin, insulin, and warfarin were associated with improved survival in patients with pancreatic cancer, whereas metformin, thiazolidinedione, statin, and combination therapies were not. The authors recommended additional studies to validate these findings in the clinical setting.

Treatment-free survival in patients with differentiated thyroid cancer.
This study evaluated treatment-free survival for 9273 patients who had differentiated thyroid cancer between 1998 and 2012. Most patients (75%) were female and median age at time of diagnosis was 69 years. The data was evaluated from the SEERS Program-Medicare registry. Five prognostic groups were identified and 5-year survival rates ranged from 96% down to 52%, and 10-year survival rates from 94% down to 39%. Factors for predicting survival rates were stage, tumor size, and treatment with radioactive iodine.

Is BRAF V600E mutation the explanation for age-associated mortality risk in patients with papillary thyroid cancer?
In this editorial, the author discusses an article appearing within the same issue. She states that the general hypothesis that age-related differences in mortality could be linked to underlying pathogenesis and specifically to oncogenic alterations is probable. She recommends confirmatory studies and concludes that this area of investigation offers potential opportunities to tailor prognostication further through a better understanding of pathogenesis.

Conditional survival in patients with thyroid cancer.
This study used data from Surveillance, Epidemiology, and End Results (SEER) registry to determine conditional 5-year disease-specific survival based on patient age, gender, and stage. It found that patients with localized thyroid cancer have excellent conditional 5-year survival, irrespective of where they are in their survivorship phase. In addition, patients with regional thyroid cancer have relatively stable conditional 5-year survival.

Health-care utilization by prognosis profile in a managed care setting: using the Surveillance, Epidemiology and End Results Cancer Survival Calculator SEER*CSC.
The authors described health service utilization patterns of subgroups of prostate cancer and colorectal cancer (CRC) patients with different relative probabilities of dying of their cancer or other conditions. They found that although a new diagnosis of cancer increased utilization of cancer-related services for an extended time period, the timing of cancer diagnosis did not appear to affect other types of utilization.

Hospitalization burden and survival among older glioblastoma patients.
The researchers performed a retrospective cohort study among patients aged 65 years and older with glioblastoma diagnosed between 1999 and 2007. They found that higher comorbidity score and black race were associated with an increased risk of being hospitalized for at least 25% of remaining life, whereas radiation, temozolomide, and extensive surgery were associated with a decreased risk.

The Surveillance, Epidemiology, and End Results Cancer Survival Calculator SEER*CSC: validation in a managed care setting.
The researchers externally validate the nomograms for prostate and colorectal cancer using data from Kaiser Permanente Colorado. Their results indicated that the colorectal and prostate cancer nomograms are reliable tools for physicians and patients to use to obtain information on prognosis and assist in establishing priorities for both treatment of the cancer and other conditions, particularly when a patient is elderly and/or has significant comorbidities.
