Tumor location of the central and nipple portion is associated with impaired survival for women with breast cancer.

BACKGROUND: Tumor location in the breast varies, with the highest frequency in the upper outer quadrant and lowest frequency in the lower inner quadrant. Nevertheless, tumors in the central and nipple portion (TCNP) are poorly studied types of breast cancer; therefore, we aimed to clarify the clinicopathological characteristics and prognostic features of TCNP. METHODS: Using the Surveillance, Epidemiology, and End Results database, we identifed 105,037 patients diagnosed with tumor in the breast peripheral quadrant (TBPQ) (n=97,046) or TCNP (n=7,991). The chi-squared test was used to compare categorical variables across TCNP and TBPQ. Cox proportional hazard models with hazard ratios were applied to estimate the factors associated with prognosis. RESULTS: The median follow-up was over 43 months. Compared with TBPQ, TCNP patients were signifcantly older (age ≥66 years: 40.4% vs 34.1%, P<0.001), with larger tumor sizes (>20 mm size: 46.9% vs 37.3%, P<0.001), higher proportions of TNM stage II-III (18.6% vs 9.9%, P<0.001), and more mastectomies (58.1% vs 37.8%, P<0.001). The breast cancer-specifc survival (BCSS)/overall survival (OS) rate was signifcantly worse for TCNP than for TBPQ. Multivariate Cox analysis showed a higher hazard ratios for TCNP over TBPQ (BCSS: hazard ratios =1.160, P=0.005, 95% CI: 1.046-1.287; OS: hazard ratios =1.301, P<0.001, 95% CI: 1.211-1.398). A subgroup analysis revealed inferior outcomes for TCNP in TNM stage II-III and breast subtype subgroup. Multivariate logistic regression indicated that TCNP was an independent contributing factor to LN metastasis. CONCLUSIONS: TCNP was associated with older age, larger tumor size, higher TNM stage, and lymph node metastasis. Compared with TBPQ, TCNP had adverse impacts on BCSS and OS.

Quality of life in women with female pattern hair loss and the impact of topical minoxidil treatment on quality of life in these patients.

Female pattern hair loss (FPHL) is the most common hair loss disorder in women and it may impact on the psychological and social activities of patients, thereby reducing their quality of life (QoL). Topical minoxidil has been shown to be effective and safe in the treatment of patients with FPHL. The aim of this study was to assess the QoL of patients with FPHL and investigate whether topical minoxidil solution treatment improves the QoL of these patients. In this study, we enrolled 125 female patients aged 16-72 years to answer visual analog scale (VAS) and dermatology life quality index (DLQI) questionnaires. Of these patients, 31 were recruited for the follow-up study after 12 months of treatment with 2% minoxidil. Each index and the change in QoL prior to and following treatment were statistically analyzed. There was identified to be a correlation between clinical severity and the values of the indices in all patients. There was a statistically significant difference between the VAS and DLQI scores prior to and following treatment with 2% minoxidil. A comparison between the good responders (n=23) and the poor responders (n=8) revealed no significant difference in the improvement of VAS and DLQI scores. The QoL of the patients was severely impaired by FPHL. The DLQI and VAS used in this study were validated as useful indices for the evaluation of QoL due to their high reliability, sensitivity and simplicity. This evaluation is recommended for the management of FPHL treatment. The results of the study demonstrated that topical minoxidil improved the QoL of the patients.
