Quality of Life After Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy (CRS/HIPEC): Cancer Survivors' Perspective Through In-Depth Interviews.

Background: CRS/HIPEC patients face unique quality of life (QoL) challenges due to advanced disease (peritoneal carcinomatosis), the extent of procedure, and risk for long-term complications. Standard QoL questionnaires are generic, focusing on tumor type and standard treatments, and likely do not capture this select population's full experience, suggesting the need for tailored instruments. We aimed to characterize the QoL challenges faced by CRS/HIPEC cancer survivors and determine whether these were captured by a standard QoL questionnaire.

Peritoneal metastases from rare ovarian cancer treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC).

Objectives: There are limited treatment options and no consensus on the management of advanced rare ovarian malignancies. Rare ovarian malignancies can present with peritoneal metastases (PM), featuring a similar presentation to more common ovarian subtypes. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is an effective treatment for PM of non-gynecologic origin and, recently, epithelial ovarian cancer.

Collaborative expertise of gynecological and surgical oncologists in managing advanced epithelial ovarian cancer.

Background: Most patients with epithelial ovarian cancer (EOC) present with significant peritoneal spread. We assessed collaborative efforts of surgical and gynecological oncologists with expertise in cytoreductive surgery (CRS) in the management of advanced EOC.

Methods: Using a prospective single-center database (2014-2022), we described the operative and oncologic outcomes of stage IIIC-IVA primary and recurrent EOC perioperatively managed jointly by gynecological and surgical oncologists both specializing in CRS and presented components of this collaboration.

Sufficient Regional Lymph Node Examination for Staging Adenocarcinoma of the Appendix.

Background: The presence of lymph node (LN) metastasis is a known negative prognostic factor in appendix cancer (AC) patients. However, currently the minimum number of LNs required to adequately determine LN negativity is extrapolated from colorectal studies and data specific to AC is lacking. We aimed to define the lowest number of LNs required to adequately stage AC and assess its impact on oncologic outcomes.

Patterns of Recurrence in Appendix Cancer After Complete Cytoreduction and Hyperthermic Intraperitoneal Chemotherapy.

Background: It is thought that low-grade (LG) appendiceal cancer (AC) demonstrates predominantly intraperitoneal recurrence (IPR) after cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC), whereas high-grade (HG) tumors progress both intra- and extraperitoneally (EPR). However, evidence supporting this conception is lacking; therefore, we assessed recurrence in various AC histologies.

Methods: A retrospective, cohort study was conducted by using a single-center database (1998-2022).

Achieving Intraperitoneal Disease Control Using Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy: Two Cases of Metastatic Breast Cancer.

Peritoneal metastases from breast cancer (PMBC) tend to occur late in the disease course and are challenging to manage. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) provide peritoneal disease control in other malignancies and may achieve similar results in PMBC. We assessed intraperitoneal disease control and outcomes in two PMBC patients after CRS/HIPEC.

Outcomes after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal dissemination from ovarian carcinosarcoma.

Background: Ovarian carcinosarcoma (OCS) is an uncommon and aggressive malignancy, with poor response to current treatment approaches and no clear guidelines. Our aim is to evaluate the outcomes of an OCS cohort after cytoreduction with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC).

Methods: A descriptive cohort study was performed.

Safety of Nephrectomy Performed During CRS/HIPEC: A Propensity Score-Matched Study.

Background: Surgeons may hesitate to perform nephrectomy (NE) during cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) due to a potential increase in morbidity. However, no data are available regarding the impact of NE on outcomes, so the authors decided to assess its safety during CRS/HIPEC.

Methods: A single-center propensity score-matched study was conducted using a prospective database (1994-2021).

Adjuvant chemotherapy for high-grade appendiceal cancer after cytoreductive surgery with hyperthermic intraperitoneal chemotherapy.

Introduction: There are no available data on the efficacy of adjuvant chemotherapy (ACT) in stage IVA/B high-grade mucinous appendiceal cancer treated with CRS/HIPEC. We evaluated the association between ACT and survival in this cohort.

Materials And Methods: A single-institution retrospective cohort study using a prospective database was conducted.

Systemic Chemotherapy for High-Grade Mucinous Appendiceal Cancer with Peritoneal Spread After Unsuccessful CRS/HIPEC.

Background: The best management of patients who have unresectable mucinous appendiceal cancer (MAC) with peritoneal spread after a failed attempt at cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is unclear. This study aimed to assess outcomes after systemic chemotherapy (SCT) for patients with unresectable peritoneal metastases from high-grade MAC.

Methods: A single-center retrospective cohort study was conducted using a prospective CRS/HIPEC database.

The Role of Microorganisms in Appendiceal Pseudomyxoma Peritonei: A Review.

Pseudomyxoma peritonei (PMP) is a rare clinical syndrome. It originates from neoplasms of the appendix and leads to the formation of peritoneal implants and the accumulation of mucinous ascites. PMP represents a spectrum of low to high-grade disease.

Iterative Cytoreduction and Hyperthermic Intraperitoneal Chemotherapy for Recurrent Mucinous Adenocarcinoma of the Appendix.

Background: Recurrence after cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) for appendiceal tumors (AT) with mucinous carcinomatosis peritonei (MCP) is common. The evidence favoring iterative procedures (iCRS/HIPEC) is limited, and its benefit is not clear for all patients.

Methods: Retrospective (1998-2020) cohorts of AT patients with MCP recurrence after the first CRS/HIPEC were analyzed.

Cytoreductive Surgery with Hyperthermic Intrathoracic Chemotherapy for Patients with Intrapleural Dissemination of Peritoneal Surface Malignancies.

Background: Peritoneal surface malignancies (PSM) can disseminate into the pleural cavity, increasing morbidity and mortality. While cytoreductive surgery with hyperthermic intraperitoneal chemoperfusion (CRS/HIPEC) improves outcomes for PSM with intra-abdominal spread, the optimal approach for patients with pleural dissemination from PSM remains unclear. It seems reasonable to apply peritoneal carcinomatosis management principles to patients with pleural lesions using CRS and hyperthermic intrathoracic chemotherapy (HITHOC).

Novel Case of Isolated Peritoneal Carcinomatosis from Metastatic Prostate Cancer Carrying a Pathogenic BRCA Mutation Treated with Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy.

We present the first case of isolated peritoneal carcinomatosis (PC) from prostate cancer carrying a previously unreported pathogenic BRCA2 mutation without other organ involvement. CT showed PC with no extra-peritoneal metastases. Treatment included neoadjuvant chemotherapy, cytoreductive surgery/hyperthermic intraperitoneal chemotherapy (CRS/HIPEC), and adjuvant chemotherapy.
