Whether sarcopenia has any impact on long-term survival of patients with surgically treated non-small cell lung cancer (NSCLC) remains unclear. We conducted a meta-analysis focusing on current topic comprehensively for the first time. ⋯ Patients with sarcopenia had a significantly worse prognosis than those without after surgical resection of NSCLC especially in those at early stage. Sarcopenia is an independent unfavorable prognostic factor for patients with surgically treated NSCLC. (246 words).

We evaluated the prognostic significance of postoperative re-elevation of cancer antigen-125 (CA-125) levels in patients with ovarian cancer and preoperative normalization of CA-125 levels after neoadjuvant chemotherapy (NAC). ⋯ Among patients with preoperative CA-125 normalization after NAC, postoperative CA-125 re-elevation had no prognostic value. Novel and reliable biomarkers reflecting the tumor response after IDS should be identified.

Sporadic desmoid-type fibromatosis (DTF) is a rare soft tissue tumor of mesenchymal origin. It is characterized by local invasive growth and unpredictable growth behavior. Three distinct mutations involving the CTNNB1 (β-catenin) gene have been identified in the vast majority of DTF tumors, which cause activation of the Wnt signaling pathway and impact prognosis. This study examines whether the different CTNNB1 mutants (T41A, S45F) occurring in DTF tumors differentially affect Wnt signaling activity, which might explain the different disease course between DTF patients harboring different CTNNB1 mutations. ⋯ No differences in the expression levels of Wnt target genes were observed between the different CTNNB1 mutation types in DTF tumors. Further studies are needed to decipher the mechanism accounting for the diverse disease courses between DTF patients with different CTNNB1 variants.

Randomized Controlled Trial Multicenter Study
Predictive factors of pathological lateral pelvic lymph node metastasis in patients without clinical lateral pelvic lymph node metastasis (clinical stage II/III): The analysis of data from the clinical trial (JCOG0212).
Mesorectal excision (ME) is the standard surgical procedure for lower rectal cancer. However, in Japan, total or tumor-specific ME with lateral pelvic lymph node dissection (LLND) is the standard surgical procedure for patients with clinical stages II or III lower rectal cancer, because lateral pelvic lymph node metastasis occasionally occurs in these patients. The aim of study was to elucidate the predictive factors of pathological lateral pelvic lymph node metastasis in patients without clinical lateral pelvic lymph node metastasis. ⋯ Patient age, tumor location, and short-axis diameter of lateral pelvic lymph node were predictive factors of pathological lateral pelvic lymph node metastasis.

The progression-free survival (PFS) is not optimal when imatinib was recommended for treatment of gastrointestinal stromal tumor (GIST) undergoing surgery after tumor local or multifocal progression. ⋯ Surgery followed by sunitinib in GIST patients with unifocal or multifocal progression on imatinib may improve PFS, compared with surgery followed by imatinib.
