Objective: To detect the expression of IGFBP-2 mRNA in gastric cancer tissues and its roles in neoplasia and peritoneal metastasis of gastric cancer.
Methods: The IGFBP-2 mRNA expression levels in the fresh tissues from normal mucosa, primary cancer and peritoneal metastasis of 35 patients with gastric cancer were determined by the quantitative real time RT-PCR method, and the samples were sliced up and stained with hematoxylin-eosin for pathologyical examination.
Results: The levels of IGFBP-2 mRNA expression in gastric primary cancer tissues were significantly higher than those in the tissues from normal mucosa and peritoneal metastasis (P<0.05). Yet, IGFBP-2 mRNA expression levels showed no difference between the tissues of normal mucosa and peritoneal metastasis (P>0.05).
Conclusion: The expression of IGFBP-2 mRNA possibly plays an important role in proliferation, differentiation and peritoneal metastasis of gastric cancer, and it might be useful in a new method for clinical prognostication and treatment of gastric cancer peritoneal metastasis.

Purpose: This study aimed to evaluate current morbidity rates following cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with colorectal cancer and peritoneal metastasis.
Methods: A total of 42 patients who underwent CRS and HIPEC for colorectal cancer with peritoneal metastasis at a single tertiary referral center between January 2022 and December 2022 were included. Perioperative outcomes and postoperative complications were prospectively assessed.

BACKGROUND Neuroendocrine carcinoma (NEC) of the cervix is rare and has high mortality and recurrence rates. The clinical symptoms of cervical NEC, such as abnormal vaginal bleeding and discharge, are similar to those of other cervical cancers. Here, we describe a case involving a 42-year-old woman with cervical NEC accompanied by an isolated large ovarian metastasis.

Ovarian cancer (OC) ranks as the fifth leading cause of cancer-related deaths in the United States, posing a significant threat to female health. Late-stage diagnoses, driven by elusive symptoms often masquerading as gastrointestinal issues, contribute to a concerning 70% of cases being identified in advanced stages. While early-stage OC brags a 90% cure rate, progression involving pelvic organs or extending beyond the peritoneal cavity drastically diminishes it.

In this editorial we examine the article by Wu published in the . Surgical resection for peritoneal metastases from colorectal cancer (CRC) has been gradually accepted in the medical oncology community. A randomized trial (PRODIGE 7) on cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) failed to prove any benefit of oxaliplatin in the overall survival of patients with peritoneal metastases from colorectal origin.

Background: Tumor deposits (TDs) can impact proper staging of cancer, which is crucial for discussing prognosis and determining the appropriate treatment plan. Our study aimed to correlate how TDs influence prognosis of resected colorectal cancer (CRC) and how to optimize tumor-node-metastasis (TNM) staging with respect to TDs for clinical decision-making.
Methods: A retrospective analysis was performed on 611 patients with CRC treated in Jiangsu Cancer Hospital from January 1, 2010 to December 31, 2020 among whom 197 had TDs.
