Comparative Study
Microinvasive breast cancer: ER, PR, and HER-2/neu status and clinical outcomes after breast-conserving therapy or mastectomy.
Contemporary clinical outcomes of microinvasive breast cancer (MIBC), defined as no focus >1 mm, are not well characterized. We document the immunophenotype, incidence of axillary metastases, and rate of recurrence in a well-defined case series. ⋯ MIBC has a favorable prognosis, and HER-2/neu overexpression, although highly prevalent, is not significantly associated with recurrence. Axillary metastases at diagnosis are small and infrequent. The cumulative incidence of LR after BCT is acceptable; however, our data confirm that negative margins (>2 mm) are required for optimal BCT outcomes.

Randomized Controlled Trial
Lifestyle risk factors associated with arm swelling among women with breast cancer.
Breast cancer-related lymphedema (BCRL) is a feared complication for breast cancer patients who have undergone axillary surgery. Although clinical risk factors for BCRL are defined, data are sparse regarding common exposures that might induce incident arm swelling. The goal of this study was to quantify the association between common exposures thought to be potential risk factors and the occurrence of incident arm swelling among breast cancer survivors with or at risk for BCRL. ⋯ In our patient cohort, many common exposures that have been reported to be risk factors did not prove to have a significant predictive relationship for incident arm swelling. This study supports the recommendation that breast cancer patients who have had axillary surgery should avoid sauna use. The results do not confirm the need for other restrictions that may interfere with the quality of life in women with breast cancer.

Multicenter Study Comparative Study
Development of criteria for ovarian preservation in cervical cancer patients treated with radical surgery with or without neoadjuvant chemotherapy: a multicenter retrospective study and meta-analysis.
There is no consensus on the selection criteria for ovarian preservation in cervical cancer, and the role of neoadjuvant chemotherapy (NACT) on ovarian metastasis (OM) is also unknown. ⋯ Ovarian preservation surgery may be safe in SCC patients without suspicious LNM, PMI, and CUI, and in adenocarcinomas in patients who received NACT without FIGO stage IIB disease, bulky tumor size (>4 cm), suspicious PMI, and CUI.

Tumor-infiltrating lymphocyte (TIL) counts in colorectal cancer liver metastases (CRCLM) predict survival following resection. While CD4 and CD8 T cells have been correlated with outcome following CRCLM resection, the role of regulatory T cells (Treg) is not well defined. ⋯ A high number of Treg relative to CD4 or CD8 T cells predicted poor outcome, suggesting an immunosuppressive role for FoxP3 + TIL. The intratumoral immune response was an independent predictor of outcome in patients with colorectal liver metastases.

The majority of thyroid cancer diagnoses in the United States are stage I well-differentiated cancer. The use of radioactive iodine (RAI) in these low-risk patients has increased over time. The role of surgeon training in decision making regarding treatment with RAI is unknown. ⋯ Training with a surgeon or group of surgeons who focus on thyroid surgery was associated with a lower proportion of stage I thyroid cancer patients receiving RAI after total thyroidectomy. This study emphasizes the importance of surgeon training in hospital practice patterns.
