Abstract
INTRODUCTION: To assess the patient's satisfaction in a day-surgery unit in oncology for a surgical diagnosis or therapeutic act.
METHODS: Between October 2013 and February 2014, we conducted a satisfaction survey from the validated questionnaire COPS-D. This questionnaire analyse the patient's stages in the care system, from the preoperative consultation to the return home: 9 stages with 23 items rated 1 (bad) to 5 (excellent). It was sent by postmail 3 weeks after their hospitalization.
RESULTS: Four hundred and sixty-seven questionnaires were mailed, with a response's rate to 38% (172/467). Participant's characteristics: 88% are women, 45% are full time workers, 54% of senology. Two-third of the assessments were rated 4 or 5. Five percent were rated 1 or 2. The patient's exit is the least preferred step. The operating room's assessment is the most preferred by patients. Sixty-one percent of participants have written a free comment, 31% are positives, 36% are negatives, and 32% are mixed. The wait was the negative recurrent comment (21%).
DISCUSSION: Most participants are very satisfied. Improving the wait before the operation and output is already underway. Studies are now needed to assess the care's safety and the economic aspect of day-surgery.

[Medical management of cholangiocarcinomas in 2015].

[Medical management of cholangiocarcinomas in 2015].

Bull Cancer. 2016 Feb 24;

Authors: Marret G, Neuzillet C, Rousseau B, Tournigand C

Abstract
Cholangiocarcinoma is a rare malignancy carrying a poor prognosis. Most patients are diagnosed with advanced-stage disease and are then ineligible for surgical resection, which is the only potentially curative therapeutic modality. The aim of this article is to provide an up-to-date review of medical management of patients with cholangiocarcinoma. The benefit of adjuvant therapy in patients undergoing curative-intent surgery is under evaluation. Combination chemotherapy with gemcitabine and platinum is the standard first-line treatment for patients with advanced cholangiocarcinoma. Targeted agents are not currently recommended due to limited data on use in this setting. The role of second-line chemotherapy is not established in advanced cholangiocarcinoma. Identification of predictive and prognostic markers to select patients who could benefit from second-line therapy is a major issue. A better understanding of the biological and molecular mechanisms underlying the carcinogenesis and the phenotypic heterogeneity of cholangiocarcinoma may path the way of new therapeutic strategies.

Long-term risk of gastrointestinal cancers in persons with gastric or duodenal ulcers

Abstract

Peptic ulcer predicts gastric cancer. It is controversial if peptic ulcers predict other gastrointestinal cancers, potentially related to Helicobacter pylori or shared lifestyle factors. We hypothesized that gastric and duodenal ulcers may have different impact on the risk of gastrointestinal cancers. In a nationwide cohort study using Danish medical databases 1994–2013, we quantified the risk of gastric and other gastrointestinal cancers among patients with duodenal ulcers (dominantly H. pylori-related) and gastric ulcers (dominantly lifestyle-related) compared with the general population. We started follow-up 1-year after ulcer diagnosis to avoid detection bias and calculated absolute risks of cancer and standardized incidence ratios (SIRs). We identified 54,565 patients with gastric ulcers and 38,576 patients with duodenal ulcers. Patient characteristics were similar in the two cohorts. The 1–5-year risk of any gastrointestinal cancer was slightly higher for gastric ulcers patients (2.1%) than for duodenal ulcers patients (2.0%), and SIRs were 1.38 (95% CI: 1.31–1.44) and 1.30 (95% CI: 1.23–1.37), respectively. The SIR of gastric cancer was higher among patients with gastric ulcer than duodenal ulcer (1.92 vs. 1.38), while the SIRs for other gastrointestinal cancers were similar (1.33 vs. 1.29). Compared with gastric ulcer patients, duodenal ulcer patients were at lower risk of smoking- and alcohol-related gastrointestinal cancers. The risk of nongastric gastrointestinal cancers is increased both for patients with gastric ulcers and with duodenal ulcers, but absolute risks are low. H. pylori may be less important for the development of nongastric gastrointestinal cancer than hypothesized.

Patients with gastric ulcer and duodenal ulcer have an increased risk of all gastrointestinal cancers, compared with the general population. Site-specific absolute cancer risks were similarly low in both Peptic ulcer disease (PUD) cohorts, and the direction of the associations with both gastric and other GI cancers was consistent among patients with the two ulcer types.

EphA4-deleted microenvironment regulates cancer development and leukemoid reaction of the isografted 4T1 murine breast cancer via reduction of an IGF1 signal

Abstract

EphA4 belongs to the largest family of receptor tyrosine kinases (RTKs). Although EphA4 is highly expressed in the central nervous system, EphA4 has also been implicated in cancer progression. Most of the studies focus on the expression and function in tumor cells. It is unknown whether EphA4-deleted microenvironment affects tumor progression. Some of cancers in animals and humans, such as 4T1 cancer cells, are known to produce a large amount of granulocyte colony-stimulating factors (G-CSF/Csf3) which can stimulate myeloproliferation, such as myeloid-derived suppressor cells (MDSCs) leading to a poor recipient prognosis. We isografted 4T1 breast cancer cells into both EphA4-knockout and control wild-type female littermate mice. The results showed that the EphA4-deleted host could inhibit primary tumor growth and tumor metastasis mainly by decreasing the amount of IGF1 synthesis in the circulation and locally tissues. The EphA4-deleted microenvironment and delayed tumor development reduced the production of G-CSF resulting in the decrease of splenomegaly and leukemoid reaction including MDSCs, which in turn inhibit the tumor progression. This inhibition can be reversed by supplying the mice with IGF1. However, an excess of IGF1 supply over demand to the control mice could not further accelerate the tumor growth and metastasis. A better understanding and re-evaluation of the main role of IGF1 in regulating tumor progression could further enhance our cognition of the tumor development niche. Our findings demonstrated that EphA4-deleted microenvironment impairs tumor-supporting conditions. Conclusion: Host EphA4 expression regulates cancer development mainly via EphA4-mediated IGF1 synthesis signal. Thus, targeting this signaling pathway may provide a potential therapeutic option for cancer treatment.

Laparoscopic surgery for patients with colorectal cancer produces better short-term outcomes with similar survival outcomes in elderly patients compared to open surgery

Abstract

The number of operations on elderly colorectal cancer (CRC) patients has increased with the aging of the population. The aim of this study was to evaluate surgical outcomes in elderly patients who underwent laparoscopic or open surgery for CRC. We analyzed the data of 280 patients aged 80 or over who underwent surgery for CRC between January 2001 and December 2010. Seventy-one pairs were selected after propensity score matching for laparoscopic or open surgery. Operative time, return to normal bowel function, length of hospital stay, postoperative complications, overall survival (OS), recurrence-free survival (RFS), and prognostic factors affecting survival were investigated. In matched cohorts, operative time in the laparoscopic group was longer than in the open group (P < 0.001). In the laparoscopic group, time to flatus passage (P < 0.001) and length of postoperative hospital stay (P = 0.037) were shorter than in the open group. The rate of operation-related morbidity was higher in the open group (P = 0.019). There was no difference in OS and RFS between two groups. This study suggests that laparoscopic surgery for CRC in elderly patients may be safe and feasible, with better short-term outcomes. OS and RFS, however, were not different in both groups.

In this study, laparoscopic colorectal surgery in elderly patients achieved better results than open surgery in terms of bowel function recovery, length of hospital stay, and postoperative complications. Overall survival and recurrence-free survival following laparoscopic and open colorectal resections were similar in the elderly population. These findings indicate that laparoscopic colorectal surgery in elderly patients is safe and feasible, and should be considered as a treatment option.

Body mass index and survival after diagnosis of invasive breast cancer: a study based on the Japanese National Clinical Database—Breast Cancer Registry

Abstract

Few studies have reported the association between body mass index (BMI) and outcome among Asian breast cancer patients. We analyzed data for 20,090 female invasive breast cancer patients who had been followed-up for a median period of 6.7 years entered in the National Clinical Database–Breast Cancer Registry between 2004 and 2006. We used mainly the WHO criteria for BMI (kg/m2) categories; <18.5 (underweight), ≥18.5–<21.8 (reference), ≥21.8–<25, ≥25–<30 (overweight), and ≥30 (obese). We divided normal weight patients into two subgroups because this category includes many patients compared to others. The timing of BMI measurement was not specified. The Cox proportional hazards model and cubic spline regression were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Smoking, alcohol, and physical activity were not controlled. A total of 1418 all-cause, 937 breast cancer–specific deaths, and 2433 recurrences were observed. Obesity was associated with an increased risk of all-cause (HR: 1.46; 95% CI: 1.16–1.83) and breast cancer–specific death (HR: 1.47; 95% CI: 1.11–1.93) for all patients, and with all-cause (HR: 1.47; 95% CI: 1.13–1.92) and breast cancer–specific death (HR: 1.58; 95% CI: 1.13–2.20) for postmenopausal patients. Being underweight was associated with an increased risk of all-cause death for all (HR: 1.41; 95% CI: 1.16–1.71) and for postmenopausal patients (HR: 1.45; 95% CI: 1.15–1.84). With regard to subtype and menopausal status, obesity was associated with an increased risk of breast cancer–specific death for all cases of luminal B tumor (HR: 2.59; 95% CI: 1.51–4.43; Pheterogeneity of Luminal B vs. Triple negative = 0.016) and for postmenopausal patients with luminal B tumor (HR: 3.24; 95% CI: 1.71–6.17). Being obese or underweight is associated with a higher risk of death among female breast cancer patients in Japan.

MiR-24 enhances radiosensitivity in nasopharyngeal carcinoma by targeting SP1

Abstract

Radioresistance remains a major problem in the treatment of patients suffering from nasopharyngeal carcinoma (NPC). A better understanding of the mechanisms of radioresistance may generate new strategies to improve NPC patients' responses to therapy. This study was designed to investigate the effect of microRNA on the radiosensitivity of NPC cells. A microRNA microarray indicated that miR-24 was downregulated in NPC cell lines and tissues. Furthermore, cell proliferation was suppressed and radiosensitivity increased when miR-24 was ectopically expressed in NPC cells. Specificity protein 1 (SP1) was additionally verified as a direct functional target of miR-24, which was found to be involved in cell viability as well as the radiosensitivity of NPC cells. In conclusion, the results of this study suggest that the miR-24/SP1 pathway contributed to the reduction in radioresistance in human NPC and that it may thus represent a therapeutic target.
