Post Mastectomy Pain Syndrome (PMPS) is a common postoperative condition for breast cancer, but has been ignored. The aim of this study was to investigate the prevalence of PMPS and the risk factors in women submitted to surgical treatment for breast cancer. The study included 532 postoperative breast cancer patients in a hospital for five consecutive years period, of whom 473 were considered eligible and included in the study. A total of 420 people completed a questionnaire survey, which revealed that 152 (36.2%) had ever suffered from PMPS and 18 (11.8%) sought treatment. Of the patients with PMPS, 34 (22.4%) had a history of chronic pain. Patients with PMPS were younger than patients without PMPS (50.5 ± 10.4 vs 53.5 ± 11.1). Univariate analysis showed that age, history of chronic pain, tumor staging, number of lymphadenectomy were significantly different between the two groups. Multivariate analysis shows that age and history of chronic pain were independent risk factors. The incidence of PMPS in postoperative breast cancer patients can reach 36.2%, and age as well as previous history of pain are independent risk factors for PMPS. The combination of prevention and treatment may be an effective way to reduce PMPS.
We investigate the impact of lung metastasis versus metastasis of bone, brain, or liver on overall survival (OS) and thyroid cancer-specific survival (TCSS) in patients with thyroid cancer (TC). Therefore, de-identified SEER 18 registry data of primary TC patients diagnosed between 2010 and 2016 were analyzed. The primary outcome was the prognosis of TC patients with lung metastasis compared with other sites. The secondary outcomes included the prognosis comparison between patients with and without surgery and between single and multiple metastasis sites. Isolated lung metastasis was associated with worse OS and TCSS than bone metastasis (both p < 0.05) and was associated with worse OS than liver metastasis (p = 0.0467). Surgery performed either for the primary or distant site was associated with better OS and TCSS in patients with metastasis of lung or bone (p < 0.05). Isolated lung metastasis was related to better OS and TCSS than lung–liver, lung–brain, and lung–other multiple metastases. The multivariable analysis revealed that age <55 years, surgery to the primary site, and to the distant site(s) were associated with better outcomes, while T4 and Tx were associated with worse outcomes. Nevertheless, it revealed that the other race (i.e., any race other than white, black, or unknown) and male gender were associated with better TCSS only (p < 0.05). Isolated lung metastasis is associated with a worse prognosis in TC patients compared with bone or liver metastasis. Surgery performed either for the primary or distant site(s) is associated with better survival outcomes in TC patients with metastasis of lung or bone.
Background: Thyroid cancer (TC) is a common malignancy. Lung metastasis is one of the top metastases for TC. The incidence and survival rates of TC with lung metastasis remain unclear.Methods: Data on TC with lung metastasis and other site-specific metastases were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Chi-square tests were employed to compare the biological and clinical features of thyroid patients with different metastatic sites. Survival analysis was performed utilizing Kaplan-Meier analysis and log-rank tests. We used a Cox proportional hazards model for the multivariate analysis to identify prognostic factors of thyroid patients with lung metastases. Statistical significance was indicated by a two-tailed P value < 0.05.Results: A total of 77322 patients suffering from TC with clear metastasis information were identified from 2010-2016. The probability of isolated lung metastasis was significantly higher than that of isolated distant metastasis to other sites among TC patients (P < 0.05). Patients with isolated lung metastases had worse overall survival (OS) and thyroid cancer-specific survival (TCSS) than patients with bone metastasis only (P < 0.05). There was a slight difference in thyroid cancer-specific survival between patients with lung metastasis and patients with liver metastasis (P=0.0496), while there was no significant difference in overall survival. (P >0.05). There was no significant difference in OS or TCSS between patients with lung metastasis and those with brain metastasis (P > 0.05). Multivariate analysis revealed that white race was associated with better outcomes in terms of both endpoints in the lung metastasis population.Conclusions: The incidence of lung metastasis from TC was higher than that of other organ metastases. Thyroid cancer patients with isolated lung metastases have worse outcomes than patients with isolated bone metastases and liver metastases but are similar to brain metastases. There was the worst survival outcome in patients with multiorgan metastases.
Purpose: The current guidelines associate indications for surgery in mitral regurgitation (MR) with left ventricle size and function. However, there is not enough emphasis in current guidelines on left atrial function, which is thought to be an important factor predicting adverse outcomes in MR. The aim of this study was to investigate the left atrial function at different stages of mitral regurgitation and its value in predicting the indications of mitral valve surgery. Methods: This was a retrospective study with 163 consecutive chronic primary MR patients who underwent color doppler echocardiography at the Guangxi Zhuang Autonomous Region Second People's Hospital between January 2016 and June 2018. All patients were in sinus rhythm, classified into three groups, according the degree of mitral regurgitation. Comparison was made with 30 control patients. Using Simpson’s methods, we recorded maximal left atrial volume, left atrial volume before active contraction and minimal left atrial volume, from which left atrial expansion index, left atrial passive emptying fraction, left atrial active emptying fraction, and the total left atrial emptying fraction were derived. Results: Left atrial volume was expanded and left atrial emptying fraction was reduced in the mitral regurgitation group. By multivariate analysis, left atrial passive emptying fraction and left atrial active emptying fraction were independent predictors of mitral regurgitation requiring surgery. Using receiver-operating characteristic analysis, left atrial passive emptying fraction <97.4% demonstrated 98% sensitivity and 67% specificity for predicting the presence of surgical indication (area under the curve: 0.91; P < .001). Conclusion: During mitral regurgitation, left atrial volume increases and functions decrease. The left atrial passive emptying fraction can be used as an additional tool to predict the indications of mitral valve surgery.
