Objective: To explore the surgical strategy of the tumors of petroclival region.
Methods: The surgical data of 55 cases presented with meningioma and trigeminal nerve sheath tumors from January 2002 to February 2009 was retrospectively analyzed. All the cases were divided into full-cut group, sub-total resection group, part of resection group or divided into full-cut group and no-total resection group, in terms of various surgical strategy. The incidence of postoperative neurological disorder and quality of life status were focused and statistical analysis was carried out.
Results: There were 21 patients with complete cut, 22 patients with sub-total resection and 12 patients with part of resection. There were 12 patients with neurological deterioration in full-cut group and 10 patients in no-total resection group. There was significant difference between total resection group and no-total resection group (χ(2) = 4.16, P < 0.05). All the patients were assessed based on the criterion of KPS, 12 patients of full-cut whose KPS ≥ 80, 29 patients were the same in no-total resection group. There was significant difference between the two groups (χ(2) = 5.42, P < 0.05). The mean follow-up time was 3 years. No recurrence was found in full-cut group and 5 recurrence of no-total resection group.
Conclusions: The pursuit of full-cut for the tumors of petroclival region may result in serious neurological dysfunction and poor life quality after the operation. Non-full-cut combination of postoperative radiotherapy may receive a relative better results.

Department of Thoracic Surgery, The First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou, 310003, China.
Background: To date, there remains a paucity of comparative investigations pertaining to preoperative immunochemotherapy and conventional chemotherapy in the context of limited-stage small-cell lung cancer (LS-SCLC) patients. This study conducted a comprehensive comparative assessment concerning the safety and efficacy profiles of preoperative immunochemotherapy and chemotherapy in individuals diagnosed with stage I-IIIB SCLC.
Methods: This investigation collected 53 consecutive patients diagnosed with LS-SCLC spanning stage I to IIIB who underwent preoperative immunochemotherapy or conventional chemotherapy at our hospital from January 2019 to July 2021.
Impact of perforation following self-expandable metal stent as a bridge to surgery for malignant colorectal obstruction: a multicenter study of the Research Group for Stent in the Korean Society of Gastrointestinal Endoscopy.

Background And Aims: Self-expandable metal stents (SEMS) are effective in alleviating malignant colorectal obstruction. However, bowel perforation following SEMS placement remains a significant concern, as it can adversely affect oncological outcomes. This study aimed to evaluate the recurrence and overall survival rates associated with SEMS-related bowel perforations.

After the World Health Organization established a precise definition of mucinous cystic neoplasm (MCN) in 2000, based on the presence of ovarian-type stroma, its clinical features became more apparent. Surgery for MCN, which primarily affects middle-aged women with long life expectancies, is likely to negatively impact the patient's quality of life. Although recent studies have reported a low proportion of advanced neoplasia among resected MCN (≤15%), many clinicians still recommend surgery for patients with presumed MCN without considering risk stratification for advanced neoplasia.

Background: Cutaneous squamous cell carcinoma (cSCC) is an aggressive tumor with unclear margins. Photodynamic diagnosis (PDD) enables the differentiation of tumor tissue from normal tissue via visible fluorescence. Photodynamic therapy (PDT) is widely used in the treatment of non-melanoma skin tumors.

Purpose: To investigate whether multiparametric quantitative diffusion weighted magnetic resonance imaging (DWI) can effectively predict the neoadjuvant therapy (NAT) response in borderline resectable pancreatic ductal adenocarcinoma (BRPC).
Methods: The clinicopathological data, including tumor size, location, and CA19-9 values, as well as DWI parameters(ADC, D, and f values) from 72 patients with BRPC, were analyzed. The differences and changes in these factors before and after NAT were compared to identify those most accurately reflect the response to NAT.
