A comparison of inflammation-based prognostic scores in patients with cancer. A Glasgow Inflammation Outcome Study

Introduction

Components of the systemic inflammatory response, combined to form inflammation-based prognostic scores (modified Glasgow Prognostic Score (mGPS), Neutrophil Lymphocyte Ratio (NLR), Platelet Lymphocyte Ratio (PLR), Prognostic Index (PI), Prognostic Nutritional Index (PNI)) have been associated with cancer specific survival. The aim of the present study was to compare the prognostic value of these scores.

Methods

Patients (n = 27,031) who had an incidental blood sample taken between 2000 and 2007 for C-reactive protein, albumin, white cell, neutrophil, lymphocyte and platelet counts, as well as a diagnosis of cancer (Scottish Cancer Registry) were identified. Of this group 8759 patients who had been sampled within two years following their cancer diagnosis were studied.

Results

On follow up, there were 5163 deaths of which 4417 (86%) were cancer deaths. The median time from blood sampling to diagnosis was 1.7 months. An elevated mGPS, NLR, PLR, PI and PNI were predictive of a reduced cancer specific survival independent of age, sex and deprivation and tumour site (all p < 0.001). The area under the receiver operator curves was greatest for mGPS and PI. Specifically, in colorectal cancer, an elevated mGPS and PI were predictive of a reduced cancer specific survival independent of age, sex, deprivation and tumour stage (both p < 0.001).

Conclusion

The results of the present study show that systemic inflammation-based scores, in particular the mGPS and PI, have prognostic value in cancer independent of tumour site. Based on the present results and the existing validation literature, the mGPS should be included in the routine assessment of all patients with cancer.     

Day-case laparoscopic Nissen fundoplication

Introduction   Nissen fundoplication has been performed laparoscopically for over 15 years, being associated with shorter hospital stay and fewer complications than conventional open surgery with good long-term outcomes. Day-case laparoscopic Nissen fundoplication (LNF) is rarely performed in the UK and most series in the literature report length of stay >2 days. Methods   The objective of this study was to examine the safety and efficacy of day-case LNF. The clinical records of all patients undergoing LNF under the care of three surgeons in a district general hospital (DGH) during a 5-year period (January 2003 to December 2007) were reviewed to examine length of stay, complications, length of procedure, grade of operating surgeon and symptoms on follow-up. Results   One hundred thirteen day-case LNFs were recorded in this series. Day-case LNF patients had median age of 45 years (range 20–68 years, 65% (64.6%) male) and 98% were American Society of Anesthesiologists (ASA) grade I or II. Twenty-one cases (19%) were performed by higher surgical trainees. Median operative time was 54 minnutes (range 25–120 min). Only one perioperative complication (port-site bleed) occurred, treated without prolonging length of stay. The proportion of all LNF performed as day cases increased from 8% to 52% during the study period. Median operative time has significantly reduced from the first 20 consecutive LNF cases to the latest 20 cases [65 min (range 40–120 min) versus 48 min (range 25–72 min); p = 0.037]. At follow-up (median 7 weeks, range 2–31 weeks) 82% of patients had improvement in all presenting symptoms. Eight patients had postoperative complications [wound infection (n = 2), persistent regurgitation requiring laparoscopic division of a gastric band adhesion (n = 1), dysphagia (n = 5 with two patients requiring redo partial fundoplication and one patient requiring dilatation) and there were no conversions to open surgery. Conclusion   Day-case LNF is safe and effective for treating selected patients with gastroesophageal reflux disease (GERD) in a DGH. The proportion of day-case LNFs is increasing in our unit. Half of the LNFs in a DGH can be done as day cases. Experience is associated with a significant reduction in operative time.     

Day case emergency laparoscopic appendectomy

Background Laparoscopic appendectomy (LA) is associated with a shorter hospital stay and fewer complications than conventional open appendectomy (OA). This study aimed to examine the safety and efficacy of day case emergency LA. Methods The records of patients undergoing emergency LA under the care of two laparoscopic surgeons over a 3-year period (Februrary 2003 to February 2006) were reviewed to examine hospital length of stay (LOS), complications, histology, grade of the operating surgeon, and time required to perform the procedure. Results A total of 104 patients (median age, 25 years; range, 11–72 years; 58 men) underwent LA, with 9 and 66 patients discharged in 8 and 24 hours, respectively (median LOS 22 hours: range 6–170 hours). One patient underwent conversion to OA. Histologically, 86 patients had appendicitis and 18 had normal appendices with another pathology present. The median operative time was 35 min (range, 20–80 min). The complications included three wound infections and two pelvic abscesses not requiring further operative intervention. Conclusion Day case emergency LA is safe and effective for treating selected patients.     

Solitary subcutaneous metastatic deposit from hepatocellular carcinoma

Hepatocellular carcinoma is the most common primary tumour of the liver. Metastasis is frequent in these aggressive tumours and is commonly to the lungs, regional lymph nodes, or bone. Metastasis as a discrete subcutaneous nodule has not been described before. We report a case of hepatocellular carcinoma with a solitary subcutaneous metastatic deposit identified 18 months after the initial hepatic surgery.     

Association between self-report pain ratings of child and parent, child and nurse and parent and nurse dyads: meta-analysis

Title.  Association between self-report pain ratings of child and parent, child and nurse and parent and nurse dyads: meta-analysis.
Aim.  This paper is a report of a meta-analysis to investigate the association between self-report pain ratings for the dyads of child and parent, child and nurse and parent and nurse.
Background.  Existing research has shown conflicting results with regard to agreements of self-report pain ratings between the three dyads.
Data sources.  The CINAHL, Medline, Ovid and PsycINFO databases were searched using keyword, such as 'children/adolescents', 'parents/nurses', 'pain assessment', 'pain ratings', 'association' and 'agreement'. Studies published in English in or after 1990 were included.
Methods.  Meta-analysis methodology was applied to 12 pain assessment studies published between 1990 and 2007 which met the inclusion criteria. In the 12 studies a common effect size was estimated using the Pearson's correlation coefficient. Therefore, a fixed-effects model was chosen for this meta-analysis.
Results.  We found moderate summary effect sizes between self-reported pain ratings for the dyad of child and parent ( r  = 0·64) and the child and nurse dyad ( r  = 0·58) and a weak summary effect size of r  = 0·49 for the dyad of parent and nurse. The summarized effect sizes for each of the three dyads varied across the studies. A test of homogeneity ( Q -statistic) indicated that all effect size estimates were not homogeneous.
Conclusion.  Parents' and nurses' perceptions of children's pain should only be considered as estimates rather than expressions of the pain experienced, and not the same as children's self-reports. There is a need for education on selection of appropriate pain assessment scales in relation to the age and development of the child.     

Postoperative wound complications and systemic recurrence in breast cancer

Many factors involved in wound healing can stimulate tumour growth in the experimental setting. This study examined the relationship between wound complications and the development of systemic recurrence after treatment of primary breast cancer. One thousand and sixty-five patients diagnosed with operable primary invasive breast cancer between 1994 and 2001 were assessed for development of systemic recurrence according to whether or not a wound complication occurred after surgery, with a median follow-up of 54 months (range 15-119). There were 93 wound complications (9%). There was a statistically significant greater risk of developing systemic recurrence in patients with wound problems than those without (hazard ratio (HR) 2.87; 95% CI: 1.97, 4.18; P<0.0001). This remained in a multivariate analysis after adjustment for case mix variables, including Nottingham Prognostic Index (NPI) and oestrogen-progesterone receptor status (HR: 2.52; 95% CI: 1.69, 3.77; P<0.0001). In the good prognostic NPI group, 4 out of 27 patients (15%) with wound problems vs 11 out of 334 (3%) without wound problems developed systemic recurrence. The corresponding figures were 10 out of 35 (29%) vs 48 out of 412 (12 %) in the moderate prognostic group and 18 out of 29 (62%) vs 75 out of 199 (38%) in the poor prognostic group. In 29 patients NPI could not be calculated. Smokers at the time of diagnosis were more likely to develop metastatic disease than the non-smokers (HR: 1.50; 95% CI: 1.04, 2.15; P=0.03) after adjustment for other factors. The results suggest that patients with wound complications at primary surgery have increased rates of systemic recurrence of breast cancer.
