Comparative StudyEffects of Neoadjuvant Chemoradiotherapy on Pathological TNM Stage and Their Prognostic Significance for Surgically-treated Esophageal Squamous Cell Carcinoma.
The TNM staging system for esophageal cancer is designed to predict survival based on pathological stage in patients who have been treated with surgery alone. However, pathological stage can vary considerably after neoadjuvant therapy due to tumor responses. ⋯ nCRT could lead to down-staged ESCC tumors for many patients and a good prognosis. The correlation between ypStage and pathological response to nCRT indicated that ypStage could stratify survival and serve as a prognostic predictor after trimodal therapy.

Long-term Tumor Control and Late Toxicity in Patients with Prostate Cancer Receiving Hypofractionated (2.2 Gy) Soft-tissue-matched Image-guided Intensity-modulated Radiotherapy.
We report the long-term tumor control and toxicity outcomes of patients undergoing hypofractionated (2.2 Gy) image-guided intensity-modulated radiotherapy (IG-IMRT) using tomotherapy for clinically localized prostate cancer. ⋯ This report involved the longest followed-up cohort of patients to have received hypofractionated (2.2 Gy) soft tissue-matched IG-IMRT using tomotherapy. The findings of this study indicate that hypofractionated IMRT is well tolerated and is associated with good long-term tumor-control outcomes in patients with localized prostate cancer.

Recurrence and Survival Outcomes After Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Small Bowel Adenocarcinoma.
Peritoneal dissemination of small bowel adenocarcinoma (SBA) is rare but is associated with a dismal prognosis. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is a promising treatment option. We evaluated our experience of CRS-HIPEC for the treatment of SBA. ⋯ CRS-HIPEC in selected patients with peritoneal dissemination of SBA is associated with reasonable mid-term survival outcomes but treatment failure is common. High disease burden, quantified by the PCI is associated with poor outcomes. A large, prospective, multi-institutional study is needed to further evaluate the outcomes of CRS-HIPEC for SBA.

Randomized Controlled TrialSurvival Analysis of Patients with Breast Cancer Undergoing a Modified Radical Mastectomy With or Without a Thoracic Paravertebral Block: a 5-Year Follow-up of a Randomized Controlled Trial.
This 5-year prospective follow-up of women randomized to general anesthesia (GA) with or without a thoracic paravertebral block (TPVB) examined the risk of local recurrence, metastasis and mortality after breast cancer surgery. ⋯ Although the original study was underpowered to properly address long-term outcomes, the results of this analysis suggest that TPVB, administered whether as a single-injection or continuous infusion during the perioperative period, had little to no appreciable effect on local recurrence, metastasis or mortality after breast cancer surgery.

Impact of CALGB 9343 Trial and Sociodemographic Variation on Patterns of Adjuvant Radiation Therapy Practice for Elderly Women (≥70 Years) with Stage I, Estrogen Receptor-positive Breast Cancer: Analysis of the National Cancer Data Base.
The Cancer and Leukemia Group B (CALGB) 9343 trial demonstrated that adjuvant radiation therapy (RT) can be omitted in women 70 years or older, with small (≤2 cm), negative lymph nodes, estrogen receptor (ER)-positive breast cancer. We examined whether RT usage following the CALGB publication had decreased over time and evaluated sociodemographic and clinical factors associated with RT omission. ⋯ During the study period, the CALGB trial publication had a minimal impact on the rate of adjuvant RT use among elderly women with small, ER-positive breast cancers. Significant variation in RT usage existed across sociodemographic strata.
