Preoperative FDG-PET/CT Is an Important Tool in the Management of Patients with Thick (T4) Melanoma
The yield of preoperative PET/CT (PET/CT) for regional and distant metastases for thin/intermediate thickness melanoma is low. Objective of this study is to determine if PET/CT performed for T4 melanomas helps guide management and alter treatment plans. Methods. Retrospective cohort of 216 patients with T4 melanomas treated at two tertiary institutions. Fifty-six patients met our inclusion criteria (T4 lesion, PET/CT and no clinical evidence of metastatic disease). Results. Fifty-six patients (M: 32, F: 24) with median tumor thickness of 6 mm were identified. PET/CT recognized twelve with regional and four patients with metastatic disease. Melanoma-related treatment plan was altered in 11% of the cases based on PET/CT findings. PET/CT was negative 60% of the time, in 35% of the cases; it identified incidental findings that required further evaluation. Conclusion. Patients with T4 lesions, PET/CT changed the treatment plan 18% of the time. Regional findings changed the surgical treatment plan in 11% and the adjuvant plan in 7% of our cases due to the finding of metastatic disease. Additionally 20 patients had incidental findings that required further workup. In this subset of patients, we feel there is a benefit to PET/CT, and further studies should be performed to validate our findings

Dermal lymphatic invasion and inflammatory breast cancer are independent predictors of outcome after postmastectomy radiation
Inflammatory breast cancer (IBC) is a clinical staging based on history and physical findings. Dermal lymphatic invasion (DLI) can occur with or without IBC. We examine how these independently affect outcome in women treated with postmastectomy radiation.
Four hundred thirty-two patients treated with postmastectomy radiation for invasive mammary cancer were assessed. Kaplan-Meier methodology was used to calculate rates of locoregional recurrence (LRR), distant metastases (DM) and overall survival (OS). Variables entered into univariate and multivariate analysis included T stage, IBC, DLI, estrogen receptor/progesterone receptor status, HER-2/neu status, N stage, extracapsular node extension (ECE), and use of chemotherapy (CT). Median follow-up is 58 months.
For all 432 patients, the rate of LRR was 3% and DM 28%. Seven percent are alive with disease (AWD) and 26% are dead of disease (DOD). Thirty-one patients had IBC without DLI, 21 had DLI without IBC, and 18 had both IBC and DLI. For DLI 10% developed LRR, 45% DM, 7.5% are AWD and 50% are DOD. Of patients with IBC, 8% developed LRR, 44% DM, 8% are AWD and 48% DOD. DLI was the only significant independent predictor for LRR (HR 4.8, P or =4 positive nodes, and CT.
DLI and IBC are independent predictors of poor outcome after postmastectomy radiation. DLI is associated with an increased risk for LRR, and IBC with worse rates of DM and OS. Patients with both features have worse outcome than those with either alone
Patients with rectal cancer after treatment of prostate cancer: A single institutition experience.
Patterns of multidisciplinary care in the management of non-metastatic invasive breast cancer in the United States Medicare patient.
PURPOSE: Multidisciplinary care (MDC) in managing breast cancer is resource-intensive and growing in prevalence anecdotally, although care patterns are poorly characterized. We sought to determine MDC patterns and effects on care in the United States Medicare patient.
METHODS: Patients diagnosed with non-metastatic invasive breast cancer from 1992-2009 were reviewed using the Survival, Epidemiology, and End Results (SEER)-Medicare linked dataset. MDC was defined as a post-diagnosis, preoperative visit with a surgical, medical, and radiation oncologist. Same-day MDC (MDC
RESULTS: Among 88,865 patients, MDC was utilized in 2.9 %, with 14.1 % of these having MDC
CONCLUSION: While increasing, few Medicare patients undergo MDC and MD
Impact of rheumatoid arthritis on radiation-related toxicity and cosmesis in breast cancer patients: a contemporary matched-pair analysis.
PURPOSE: To evaluate the impact of rheumatoid arthritis (RA) on toxicity and cosmesis in women undergoing radiotherapy for breast cancer.
METHODS: We queried an institutional database for women with RA treated with external beam radiotherapy for breast cancer between 1981 and 2016. Matching each patient to three controls without RA was attempted. Radiation toxicity was graded using CTCAE 4.0. Cosmesis was graded using the Global Harris Scoring System of Excellent, Good, Fair, or Poor. Grade 2+ (G2+) acute and late toxicities were compared between women with RA and their matched pairs using a generalized estimating equation (GEE). Wilcoxon test and mixed effects model were used to compare the cosmesis between two groups.
RESULTS: Forty women with RA at time of radiation were matched to 117 controls. The median radiation dose was 60 Gy (50-66 Gy) and the median follow-up was 94 months (1-354 months). When comparing the women with RA to their matched pairs, there was no significant difference in the rates of G2+ acute toxicity (25.0 vs. 13.7%, O 2.1, CI 0.91-4.9) or G2+ late toxicity (7.5 vs. 4.3%, OR 1.8, CI 0.48-6.8). Mean cosmesis was between Good and Excellent for both groups of patients, although women with RA were less likely to get Excellent cosmesis compared to their matched pairs (OR 0.35, CI 0.15-0.84).
CONCLUSIONS: Among women with RA, radiation for breast cancer was well tolerated without significantly increased toxicity. Their cosmesis was generally Good to Excellent, although they might be less likely to get Excellent cosmesis compared to their matched pairs

Predictive Value of Leukocyte- and Platelet-Derived Ratios in Rectal Adenocarcinoma
Advances in treatment of rectal cancer have improved survival, but there is variability in response to therapy. Recent data suggest the utility of the lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) in predicting survival. Our aim was to examine these ratios in rectal cancer patients and determine whether any association exists with overall survival (OS).
Using prospectively maintained institutional data, a query was completed for clinical stage II-III rectal adenocarcinoma patients treated from 2002 to 2016. We included patients who had a complete blood count collected before neoadjuvant chemoradiation (pre-CRT) and again before surgery (post-CRT). The LMR, NLR, and PLR were calculated for the pre-CRT and post-CRT time points. Potential cutpoints associated with OS differences were determined using maximally selected rank statistics. Survival curves were compared using log-rank tests and were adjusted for age and stage using Cox regression.
A total of 146 patients were included. Cutpoints were significantly associated with OS for pre-CRT ratios but not for post-CRT ratios. Within the pretreatment group, a “low” (4.47) NLR and “high” PLR (>203.6) were associated with decreased OS (log-rank P < 0.001). With covariate adjustment for age, and separately for final pathologic stage, the associations between OS and LMR, NLR, and PLR each retained statistical significance.
If obtained before the start of neoadjuvant chemoradiation, LMR, NLR, and PLR values are accurate predictors of 5-y OS in patients with locally advanced rectal adenocarcinoma
