A prospective pilot study to assess neoadjuvant chemotherapy for unresectable peritoneal carcinomatosis from colorectal cancer

AIM: Twelve to 13% of patients with colorectal cancer (CRC) develop peritoneal carcinomatosis (PC), the majority of whom present with unresectable disease. This study aimed to document the actual response rate to and response characteristics of preoperative modern systemic chemotherapy in this patient group.METHOD: Patients underwent a positron emission tomography (PET)/CT scan, laparoscopy and pe

The use of Oxaliplatin or Mitomycin C in HIPEC treatment for peritoneal carcinomatosis from colorectal cancer : a comparative study

BACKGROUND: Oxaliplatin and Mitomycin C (MMC) are both suitable as intraperitoneal chemotherapy agents in HIPEC for peritoneal carcinomatosis (PC) of colorectal cancer (CRC).METHODS: Patient cohorts from two different HIPEC-centers underwent cytoreductive surgery and HIPEC with Oxaliplatin (39 patients) and MMC (56 patients), respectively. They were compared for toxicity and survival data. The ext

Morbidity associated with colostomy reversal after cytoreductive surgery and HIPEC

BACKGROUND: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has improved the survival in selected colorectal cancer patients with peritoneal metastases. In these patients, the risk of a low anastomosis is sometimes diminished through the creation of a colostomy. Currently, the morbidity and mortality associated with the reversal of the colostomy in this population

Cytoreduction and HIPEC in the Netherlands : nationwide long-term outcome following the Dutch protocol

PURPOSE: This nationwide study evaluated results of cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal metastasis of colorectal origin in the Netherlands following a national protocol.METHODS: In a multi-institutional study prospective databases of patients with peritoneal carcinomatosis (PC) from colorectal cancer and pseudomyxoma peritonei

Secondary cytoreductive surgery and peri-operative intraperitoneal chemotherapy for peritoneal recurrence of colorectal and appendiceal peritoneal carcinomatosis following prior primary cytoreduction

PURPOSE: Primary cytoreductive surgery (CRS) and peri-operative intraperitoneal chemotherapy (PIC) is the only curative option for patients with colorectal cancer peritoneal carcinomatosis (PC). A significant proportion of patients develop peritoneal recurrence. Outcomes of patients undergoing secondary CRS and PIC for recurrent PC were examined.METHODS: All patients undergoing second procedures w

Addition of biological therapies to palliative chemotherapy prolongs survival in patients with peritoneal carcinomatosis of colorectal origin

OBJECTIVES: Combination chemotherapy regimens have shown promising results in patients with metastatic colorectal cancer. However, only very few studies have studied the effect of palliative chemotherapy in peritoneal carcinomatosis (PC) and no data are present incorporating biological therapies in the treatment of PC in colorectal cancer.METHODS: By means of merging with the regional Eindhoven Ca

Multidisciplinary discussion and management of rectal cancer : a population-based study

BACKGROUND: The purpose of the present study was to evaluate the value of discussing rectal cancer patients in a multidisciplinary team (MDT).METHODS: All treated rectal cancer patients (>T1M0) diagnosed in 2006-2008 were included. According to the national guidelines, neoadjuvant (chemo)radiotherapy should be given to all rectal cancer patients. Patients were scored as "discussed" (MDT+) only if

Probing the electronic and optical properties of quantum cascade lasers under operating conditions

We report the realisation of spectroscopic broadband transmission experiments on quantum cascade lasers (QCLs) under continuous wave operating conditions for drive currents up to laser threshold. This technique allows, for the first time, spectroscopic study of light transmission through the waveguide of QCLs in a very broad spectral range (λ~1.5-12 μm), limited only by the detector response and b

Speaking in a Situation : Ovid and the Ethopoeia

The Augustan poet Ovid (43 BC – AD 17/18) is mentioned by Seneca the elder for his oratorical skills as a school boy. If we are to believe Seneca, Ovid excelled to such a degree that he even surpassed his teachers. He took special interest in exercises concerning ethos, and is said to have transferred what he learned into his own verse. The influence from rhetorical training is indeed visible in O
