Active clinical trials for "Appendiceal Neoplasms"

Patients ≥ 18 years old who have been diagnosed with appendiceal cancer with peritoneal metastases, have had cytoreductive surgery, have availability of archival tumour tissue and have consented to our institutional biobank program or have a waiver of consent for deceased patients who have not had the opportunity to provide biobank consent (requested at the time of ethics review). Descriptive analysis of the proportion of genetic mutations identified in appendiceal cancers. This is given by the percentage of pathogenic mutations in the peritoneal metastasis compared to the primary tumour.

This study seeks to justify performing an incidental appendectomy according to the following hypotheses: The frequency of neoplasms in pathohistological (PHD) findings of incidental appendectomy (IA) is significantly higher than in PHD findings in appendectomies for acute appendcitis (AA) The number needed to treat (NNT) for appendiceal tumors in the elderly is less than 500. The rate of complicated AA in the elderly population is significantly higher than in the younger age group NNT IA for complicated appendicitis in the elderly is less than 300. NNT IA for potential death due to AA in the elderly is less than 500.

This randomized pilot trial studies how well two supportive programs work for improving fatigue and depressive symptoms in patients with GI undergoing chemotherapy. Possible mediators such as psychological stress, circadian disruption, and inflammation, will also be explored.

Patients with primary peritoneal cancer or secondary peritoneal cancers from stomach, colorectal, appendiceal, and gynecological primary origin will be screened by pathology and staging to see if they are eligible to undergo cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC). To be eligible for the study, patients must be over 18 years of age, have appropriate pathology and stage with disease confined to the peritoneal cavity, have a good performance status, have laboratory values that fall within safe ranges to undergo an operation and receive intraperitoneal chemotherapy. The chemotherapeutic agent and dose will be assigned based on pathological diagnosis in accordance with current standard of care. Surgery will be performed with the goal of removing all visible tumor that may require removal of adjacent organs. Once only microscopic disease is present, the chemotherapy will be delivered directly into the peritoneum via intraperitoneal hyperthermia and perfusion device. This will continue for 90 minutes. Patients will be followed for tumor response, survival, toxicity, complications, quality of life, and tumor markers. They will have regular follow up visits with the surgeon, undergo routine surveillance imagings, and receive follow up phone calls periodically.

Mitomycin-C (MMC) is the most commonly used chemotherapeutic agent for hyperthermic intraperitoneal chemotherapy (HIPEC) after cytoreductive surgery (CRS) to treat colorectal cancer patients with peritoneal metastases. However, MMC has a side effect of myelosuppression. Particularly, severe neutropenia after CRS with HIPEC can be a life-threatening condition. Despite the postoperative risks of this side effect, the causes and risk factors for severe neutropenia after CRS followed by HIPEC is not identified so far. Therefore, in this study, we aimed to evaluate to evaluate clinical risk factors and pharmacologic properties after CRS with HIPEC using MMC in patients with colorectal cancer or appendiceal mucinous neoplasms with peritoneal metastases.

A few studies investigated the predictors of overall survival in appendiceal adenocarcinoma. A SEER database analysis of 1404 patients with appendiceal adenocarcinoma found that older age, T4 tumors, N1-2 stage, poorly differentiated carcinoma, and distant metastasis were significantly predictive of poorer survival. Another small single-center study including 49 appendiceal cancer patients reported female gender and low-grade adenocarcinoma to be associated with increased overall survival. However, these previous analyses did not take into account some important prognosticators of survival such as patients' comorbidities and functional status, pathologic parameters such as lymphovascular invasion, and adjuvant systemic treatment. Therefore, we used the National Cancer Database (NCDB) to conduct a comprehensive analysis of the predictors of overall survival after surgical treatment of stage I-III appendiceal adenocarcinoma.

The goal of this survey of international HIPEC (Hyperthermic Intraperitoneal Chemotherapy) surgeons is to determine their knowledge of and attitudes towards the nutritional support needs of HIPEC patients and what their practice patterns are with this patient population.

The aim of the present project is to evaluate the frequency of distant metastases and clinically relevant relapse and mortality, respectively, of aNEN (Neuroendocrine Neoplasms of the Appendix) measuring 1 - 2 cm. The investigators hypothesize that the mortality rate of aNET (Neuroendocrine Tumors of the Appendix) measuring 1 - 2cm is less than 1%. Furthermore, the investigators hypothesize that regional lymph node metastases of aNET measuring 1 - 2 cm are clinically not relevant and are not associated with reduced survival. The investigators therefore hypothesize that oncological right-sided hemicolectomy has no impact on long-term survival after complete resection of aNET measuring 1 - 2 cm and that the malignant potential quo ad vitam of these tumors is lower than the risk of oncological hemicolectomy.

The FANCY study will investigate whether a selective policy of histopathological examination of appendices and gallbladders based on the intraoperative findings of the surgeon is safe and cost-effective.

Multicentric, international, web-based prospective documentation of the indications and results of Pressurized Aerosol Chemotherapy (so-called PIPAC or PITAC) for treating malignant pleural and peritoneal diseases. Indication is decided by the treating physician. There are no predefined inclusion or exclusion criteria.
