Prostate cancer non-ascitic peritoneal carcinomatosis after robot-assisted laparoscopic radical prostatectomy: three case reports and review of the literature
Robot-assisted laparoscopic radical prostatectomy (RALRP) is one of the treatment options for localized prostate cancer, with an excellent disease control rate. However, these patients can experience late disease recurrence with metastatic dissemination. Peritoneal metastases are an uncommon recurrence site. Here, we discuss three cases of peritoneal metastases following RALRP and the mechanisms of peritoneal invasion. Through a literature review and our case reports, we postulate the existence of two distinct mechanisms of peritoneal invasion: one being iatrogenic, following a laparoscopic surgery with a well differentiated prostate cancer at a non-advanced stage of the disease, the other involving the natural course of poor-prognosis tumours, even without surgery.
Conclusion: Our study demonstrated that the aberrant expression of CDCA gene family members plays an indispensable role in tumorigenesis. PMID: 31955607 [PubMed - as supplied by publisher]

UsovAbstractFucosylated chondroitin sulfate (FCS) HeSp was isolated from the Patagonian sea cucumber Hemioedema spectabilis. Ion-exchange chromatography was applied for purification of the FCS from the crude extract of sulfated polysaccharides. Analysis of monosaccharide and sulfate content of HeSp revealed the molar ratio of GlcA:GalNAc:Fuc:SO3Na as 1.15:1:1.1:3.9. Molecular weight...

Rationale: The problem of the coexistence of gastrointestinal stromal tumor (GIST) with other neoplasms is complex, and carcinomas of prostate is one of the common types of GIST-associated cancers. Doubling time of GIST is about 3.9 months for high-risk GIST, and the treatment paradigm for GIST has required the integration of surgery and molecular therapy. Patient concerns: A 70-year-old man with postoperative history of prostate cancer experienced fast-growing malignant jejunal GIST with multiple peritoneal metastases within 1 year. Diagnoses: Enhanced computed tomography (CT) detected a neoplasm of small intestin...
We report a case of urachus metastases showed on 68Ga-PSMA PET/CT performed for biochemical recurrence with a very low PSA level at 0.50 ng/mL.

We report a case of 68Ga-PSMA PET/MR–positive peritoneal metastasis as site of primary relapse after definitive PCa treatment in a 58-year-old man with a prostate-specific antigen of 30 ng/mL at time of the study. Exploratory laparoscopy and subsequent histopathologic examination confirmed nonascitic peritoneal PCa carcinomatosis.
Conclusion: F-18 FDG PET/CT has high diagnostic accuracy for detection of residual/recurrent disease in stomach cancer after treatment. Metachronous primary malignancy may also be incidentally detected. Research Support: N A
We present a case of non-ascitic omental metastasis of prostate cancer without any bone metastases. Furthermore, this patient has had two negative measurements of circulating tumor cells (CTCs) in the blood, suggesting a non-hematogenous route of metastasis to the omentum.
Abstract The authors present a rare case of prostate adenocarcinoma with peritoneal carcinomatosis demonstrated by F‐18 FDG PET/CT imaging. Traditionally, prostate cancer metastasizes to bones, lung, liver, pleura, and adrenal glands. The peritoneal carcinomatosis, seen in this case, may mimic dissemination of malignancy originating from the gastrointestinal tract, ovaries, breasts, lungs, and uterus.
