Intraoperative Diagnosis Using Sentinel Node Biopsy with Indocyanine Green Dye in Gastric Cancer Surgery: An Institutional Trial by Experienced Surgeons

Background

Reliable indicators that can intraoperatively determine the absence of nodal metastasis are in great demand to avoid unnecessary lymphadenectomy. However, little has been reported about the intraoperative diagnostic performance of sentinel node (SN) biopsy.

Methods

Sentinel node biopsy by subserosal or submucosal injection of indocyanine green (ICG) was performed in 241 patients with American Joint Committee on Cancer tumor, node, metastasis staging system, 7th edition, clinical T1 (n = 190) and T2 (n = 51) gastric cancer by two experienced surgeons. All nodes that stained green (green node, GN), representing SNs, were excised before gastrectomy and were sliced into 2-mm sections for intraoperative histological examinations with hematoxylin and eosin staining. The sliced GNs were also examined simultaneously by imprint cytology.

Results

The GNs were detectable in 240 patients (3.8 ± 2.4 nodes per patient; range 1–17 nodes; median 3 nodes), and the success rate of detection was 99.6 % (240 of 241). Of 240 patients with a successful detection, 29 were found to have lymph node (LN) metastases; 16 were diagnosed with LN metastases in both GNs and non-GNs, 12 in GNs alone, and 1 in non-GNs alone. The false-negative rate based on the SN concept was 3.4 % (1 of 29). However, two patients with cT1 gastric cancer were diagnosed as intraoperative GN negative but were later confirmed as GN positive by histological examinations of paraffin sections. As an intraoperative diagnosis, the false-negative rate was 10.3 % (3 of 29).

Conclusions

Sentinel node biopsy using ICG could be performed intraoperatively within reasonable limits under certain conditions, such as multiplanes for detection, combination use of imprint cytology, and open surgery by experienced surgeons.     

Outcomes after curative or palliative surgery for locoregional recurrent breast cancer

Background

Locoregional recurrence (LRR) after breast cancer is an independent predictor for later systemic disease and poor long-term outcome. As the surgical treatment is complex and often leaves the patient with extensive defects, reconstructive procedures involving flaps, and thus plastic surgical assistance, are often required. The aim of the present study was to evaluate our institution’s approach to surgical treatment for locoregional recurrence of a breast cancer.

Methods

In the present retrospective, single-centre study, we evaluate our experience with 12 patients who underwent surgery for locally recurrent breast cancer at Aarhus University Hospital between 2006 and 2010. Nine patients underwent wide local excision. The remaining three patients underwent full thickness chest wall resection.

Results

There was no perioperative mortality and no major complications. Minor complications occurred in four (33 %) of the patients. Median overall survival was 22 months, regardless of the surgery being curative or palliative. A median disease-free survival of 18 months was achieved for patients having achieved radicality.

Conclusions

Both wide local excision and full thickness chest wall resection offer the opportunity of local control and palliation in patients with LRR. The plastic surgical reconstructive procedures are associated with a low complication rate, and thus not postponing further adjuvant therapy. However, a multidisciplinary approach with a highly careful patient selection is critical in order to ensure the best outcome for the patient. Level of Evidence: Level IV, therapeutic study.     

Is dermatome shaving a potential treatment for actinic keratosis in organ transplant recipients? A cross-sectional study

Background

Non-melanoma skin cancer (NMSC) is correlated with high morbidity and mortality in solid-organ transplant recipients (OTR) and it appears after a mean interval of 8 to 10 years. Prophylactic treatments are still required to prevent the development of NMSC. This study aims to investigate whether dermatome shaving reduced the occurrence of keratotic skin lesions in OTRs.

Methods

A retrospective study was conducted. One thousand and twenty-four patients who had a split-thickness skin graft due to NMSC excision were identified in the Central Denmark Region and the Region of Southern Denmark between 1996 and 2011. Eleven of these patients were OTRs at the time of split-thickness skin grafting and were included in the study. The patients were examined for keratotic skin lesions, representing suspected premalignant lesions, on the donor area of the split-thickness skin graft, recipient area and two corresponding control areas. Epidemiological and medical parameters for each patient were registered via medical records and through patient interviews.

Results

The average time between split-thickness skin grafting and clinical examination was 6.2 years (1.1–16.8). The occurrence of keratotic skin lesions were lower in the donor area compared to both of the control areas (Wilcoxon matched-pairs signed-rank test, p?=?0.024, respectively, p?=?0.019).

Conclusions

Dermatome shaving reduced the occurrence of keratotic skin lesions in OTRs and might prevent the development of field cancerization and NMSC. Level of Evidence: Level III, therapeutic study.     

Impact of pharmaceutical care on adherence, hospitalisations and mortality in elderly patients

Background Elderly polypharmacy patients may be more at risk of not adhering to medication. If so, the underlying reasons may be more readily disclosed during private discussions with patients. Hence pharmaceutical care discussions at home might improve treatment adherence. Objective The aim of this study was to investigate the impact of pharmaceutical care on medication adherence, hospitalisation and mortality in elderly patients prescribed polypharmacy. Setting Pharmaceutical care discussed at home. Methods A randomised controlled trial with two arms; pharmaceutical care (n = 315) and controls (n = 315) was designed. It involved patients aged 65+ years living in Aarhus, Denmark who used five drugs or more without assistance. Pharmacists visited the pharmaceuticalcare patients at home, once only, and followed them during the subsequent year with three telephone calls. Non-adherence was measured by a pill-count. Patients were categorised as non-adherent if their mean adherence rate for all drugs consumed was <80 %. The impact of pharmaceutical care on non-adherence and hospitalisation was analysed by 2 × 2 tables, and mortality by Cox regression. Main outcome measure Medication adherence, hospitalisation and mortality. Results The final analyses included 517 patients (median age 74 years; females 52 %). Dropouts were more frequent for the pharmaceutical-care group than for controls. Pharmacists encountered drug-related problems amongst 72 % of pharmaceutical-care patients. Pharmaceutical-care patients (11 %) and control patients (10 %) were similarly nonadherent (Odds ratio 1.14; 95 % confidence interval 0.65–2.00), and similar with respect to hospitalisation frequency (30 vs. 28 %; Odds ratio 1.14; 95 % confidence interval 0.78–1.67) and mortality (7.5 vs. 5 %; Hazard ratio 1.41; 95 % confidence interval 0.71–2.82). Conclusions Pharmaceutical care given to our elderly polypharmacy patients made no significant impact on medication adherence, hospitalisation or mortality, when compared to comparable control patients.
