Progress of Lung Margin During Sublobar Resection for Early-staged Non-small Cell Lung Cancer / 中国肺癌杂志

In recent years, with the popularization of low-dose computed tomography (LDCT) and high-resolution CT (HRCT), the discovery rate of early-staged non-small cell lung cancer has been on the rise, and more thoracic surgeons have explored more reasonable resection scope. Clinical studies have demonstrated that there is a lower rate of local tumor recurrence in patients with negative lung margins compared with positive ones. Therefore, it is of great clinical significance to ensure the negative margin during sublobar resection for early-staged lung cancer. This paper will focus on this area.

Challenges in management of phyllodes tumors of the breast: A retrospective analysis of 150 patients.

Introduction: Phyllodes tumors (PT) of the breast seem to get pre-operatively misdiagnosed as fibroadenomas resulting in inadequate resections and high local recurrence rates. Materials and Methods: Data of 150 patients with PT of the breast managed from January, 2003 to February, 2013 were retrospectively analyzed. Statistical analysis performed using SPSS version 17 (Pearson Chi-square test and analysis of variance test for analysis). Aim: The aim of this study is to compare clinico-pathological profile and recurrence rates in patients with benign (B), borderline malignant (BL) and malignant (M) PT. Results: In a total of 150 patients with PT (n = 77 B, n = 24 BL, n = 49 M), mean age was 36.92, 44.04 and 40.46 years respectively (P 0.015) and mean tumor size being 8.15 cm, 14.7 cm and 12.9 cm respectively (P 0.000). Pre-operatively cytology suggestive of PT in 24% patients with B PT and 63% in M PT; core tissue biopsy suggestive of PT in 85.4% patients with B PT and 100% in M PT. Recurrence seen in 34.7% out of which 32.7% were post-lumpectomy performed elsewhere. Majority of B PT had lumpectomy (49.3%)/wide local excision (WLE, 31.2%) compared with M PT where 55.1% had simple mastectomy (SM) due to large tumor size. Local recurrence was more in M PT (53%) compared with B PT (20%). We found recurrence rates in L (39.3%) compared with WLE (27.3%) and SM (33.9%) (P 0.049). Conclusions: Larger tumor size, incomplete resection and M/BL histology predicted higher recurrence in PT. Core biopsy is much more accurate than fine needle cytology in the diagnosis.
