Contralateral axillary lymph node metastases at the time of primary breast cancer diagnosis: curative or palliative intent?

Contralateral axillary lymph node metastases (CAMs) in breast cancer patients are uncommon. CAM can be found at the time of primary breast cancer diagnosis or following prior treatment of breast cancer as a recurrence. This distinction may have important implications for disease staging and treatment selection. We report the case of a premenopausal woman with synchronous CAM. Despite extensive multimodality treatment, a recurrence was found 27 months after primary surgery. We reviewed the literature on histopathological tumor characteristics associated with CAM, lymphatic drainage of the breast to other sites than the ipsilateral axilla, and outcome of cases with CAM. This case contradicts current conceptions that CAM only develops from tumors with poor histopathological features. Emerging evidence shows that altered lymphatics play a central role in development of synchronous CAM. It is precisely this etiology that supports the concept that synchronous CAM occurs by lymphatic spread and not by hematogenous spread. Although controversial, treatment of synchronous CAM (without evidence of distant metastases) should therefore be of curative intent.

Adherence to Enhanced Recovery After Surgery and length of stay after colonic resection.

AIM: The Enhanced Recovery After Surgery (ERAS) programme is a multimodal approach to improve peri-operative care in colon surgery. The aim of this study was to report on the adherence to and outcomes of ERAS in the first years after implementation. METHOD: Data of patients undergoing elective colon resections for malignancy in 2006 until 2010 were compared with patients receiving conventional care in 2005. Retrospective analysis was performed including length of stay (LOS), protocol adherence and complications. The predictive values of ERAS items and baseline characteristics on LOS and complications were analysed using univariate and multivariate analysis. RESULTS: Length of stay (LOS) was significantly shorter in 2006 and 2007 (P ≤ 0.009 and P ≤ 0.004) but not in 2008 and 2009. The mean adherence rate to the ERAS items was 84.1% in 2006 and 2007 and 72.4% in 2008 and 2009 (P < 0.001). In 2005, 2008 and 2009 LOS was significantly shorter for laparoscopically operated patients than for patients with open resections (P < 0.002, P < 0.001 and P < 0.004 respectively). Multivariate analysis showed that age, laparoscopic surgery, removal of nasogastric tube before extubation, mobilization within 24 h after surgery, starting nonsteroidal anti-inflammatory drugs at day 1 and removal of thoracic epidural analgesia at day 2 were independent predictors of LOS. CONCLUSION: Strict adherence to the ERAS protocol was associated with reduced LOS and improved outcome in elective colon surgery for malignancy. These benefits were lost when protocol adherence was lower. Embedding the ERAS protocol into an organization and repetitive education are vital to sustain its beneficial effects on LOS and outcome.

Ultrasound and fine needle aspiration cytology of axillary lymph nodes in breast cancer. To do or not to do?

AIM: The purpose of our study was to evaluate the accuracy of axillary ultrasound and ultrasound-guided fine needle aspiration cytology (FNAC) in the preoperative diagnosis of axillary metastases. METHODS: Between 2004 and 2009, 1132 female patients were evaluated and treated in our clinic for histologically proven breast carcinoma. Preoperative axillary ultrasound with subsequent FNAC in case of suspicious lymph nodes was performed in 1150 axillae (18 bilateral breast carcinomas). We analyzed the results of axillary ultrasound and FNAC retrospectively. Pathological node status was used as the reference standard (based on axillary dissection or sentinel node biopsy). RESULTS: Axillary ultrasound showed suspicious lymph nodes in 327 axillae (28.4%). FNAC showed axillary metastases in 107 of these 327 axillae. Final histological analysis confirmed 106 metastases (one false positive). Histological analysis showed metastatic disease in 429 of 1150 axillae (37.3%). Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of axillary ultrasound alone were 43.8% (188/429), 80.7% (582/721), 57.5% (188/327) and 70.7% (582/823), respectively. When combining axillary ultrasound with FNAC of suspicious lymph nodes, sensitivity was 24.7% (106/429), specificity was 99.9% (720/721), PPV was 99.1% (106/107) and NPV was 69.0% (720/1043). CONCLUSIONS: 106/429 (24.7%) Node-positive axillae were identified by ultrasound-guided FNAC and spared unnecessary sentinel node biopsy. Unfortunately, the percentage of false negative results of ultrasound-guided FNAC (28.1%, 323/1150) was very high.

Modified onlay technique for the repair of the more complicated incisional hernias: single-centre evaluation of a large cohort.

BACKGROUND: The repair of incisional hernias remains a challenge for the general surgeon. Indications for surgery are severe bowel obstruction, as well as aesthetic problems. There are various surgical methods to correct these hernias, with varying results. However, the gold standard has not yet been found. Both laparoscopic repair and the component separation technique (CTS) have proven to be acceptable techniques; however, they are not always suitable for resolving the more complicated abdominal wall defects, i.e. after open-abdomen treatment or fascial necrosis. In our hospital, we developed a new onlay technique which we have evaluated in the following research. PATIENTS AND METHODS: During a period of 10 years (1996-2007), 101 patients with an incisional hernia were corrected with the new onlay technique. A Marlex mesh of dimensions at least 10 x 20 cm was used, overlapping the fascia by at least 5 cm on each side. This mesh was stapled onto the fascia with skin staples. Of the 101 patients, there were 45 men and 56 women, with a mean age of 55 years. Nine patients died and 13 were lost during follow-up. Of the remaining 79 patients, eight refused to participate. The mean follow-up time was 64 months (normal distribution, standard deviation [SD] 34 months). This cohort of 101 patients was studied retrospectively. RESULTS: Seventy-one of the 101 patients were evaluated at our out-patient clinic. For 24 patients (25%), the operation was for a recurrence after an incisional hernia correction in the past. Twenty-one patients (20%) had an open-abdomen treatment in their medical history. The surgical procedure was technically possible in all patients and the mean operation time was 63 min. The median admission time was 4.5 days (quartiles 3-6.25). The mean follow-up time was 64 months (SD 35 months). A seroma was reported in 27 of 101 patients (27%) and a wound infection in 22 patients (21%), of which seven patients had to be re-operated. Only if a patient was evaluated at our out-patient clinic could reherniation have been scored; this occurred in 11 of 71 patients (16%). CONCLUSION: This technique is an effective and simple procedure to correct incisional hernias with acceptable complication rates and is feasible even in the more complicated hernias.

Health-related quality of life in patients treated for incisional hernia with an onlay technique.

BACKGROUND: An incisional hernia is a frequent complication of abdominal surgery. The repair of incisional hernias comes with a high risk of reherniation and serious complications. With the introduction of mesh repair, recurrence rates have decreased and subsequent clinical outcomes have improved. Whereas further research needs to be done to improve complication rates and recurrence, the focus has now been placed on quality-of-life outcomes in patients undergoing these repairs. The aim of this study was to investigate the long-term health-related quality of life (HRQL) of patients who were treated for incisional hernias using an onlay technique. PATIENTS AND METHODS: Over a period of 10 years (1997-2007), 101 patients with an incisional hernia were treated with an onlay marlex mesh, fixed on the fascia with skin staples. Of the 101 patients, there were 45 males and 56 females, and their mean age was 55 years. Nine patients died and 13 were lost during follow-up. Of the remaining 79 patients, eight refused to participate. The mean follow-up time was 64 months (normal distribution, standard deviation [SD] 35 months). The Short Form 36 (SF-36) and the Karnofsky Performance Status Scale (KPS) and a semi-structured interview were used to measure HRQL. RESULTS: Seventy-one of the 101 patients were evaluated at our out-patient clinic. Twenty-one patients (20%) had an open-abdomen treatment in their medical history. The median admission time was 4.5 days (quartiles 3-6.25). The mean follow-up time was 64 months (SD 35 months). A seroma was reported in 27 of the 101 patients (27%) and a wound infection in 22 patients (21%), of which five patients had to be re-operated. Only if a patient was evaluated at our out-patient clinic could reherniation be scored; this occurred in 11 of 71 patients (16%). The evaluation of HRQL showed equal SF-36 scores for patients treated for an incisional hernia compared to their matched controls. Patients with a history of an open-abdominal treatment did not score significantly lower compared to patients without such a treatment. The median KPS score was 75, indicating that activities could be performed with effort and patients had some signs of disease. CONCLUSION: HRQL is the same in patients treated for an incisional hernia compared to the matched controls. Therefore, the onlay technique seems to be an acceptable method to repair large incisional hernias.

Effect of increased (99m)Tc/(99)Tc ratios on count rates in sentinel node procedures: a randomised study.

The aim of this study was to evaluate the count rates of sentinel lymph nodes (SLNs) in patients with breast cancer in the operating theatre, using (99m)Tc-Nanocoll with different ratios of technetium-99m to technetium-99. After written informed consent had been obtained, we tested different ratios of (99m)Tc/(99)Tc-Nanocoll in a double-blinded randomised study performed in 161 patients. Twenty-five MBq/ microg (99m)Tc-colloid albumin was prepared in vacuum. In 87 patients (group A) a 2-h elution was used and in 74 patients (group B) a 24-h elution was used. Patients were subcategorised into subgroups 1 and 3, in which an SLN procedure for breast carcinoma was performed simultaneously with lumpectomy, and subgroups 2 and 4, in which an SLN procedure was performed 2-3 weeks after prior excision biopsy. All patients were injected along the lateral border of the areola (two injections: 50 MBq/0.3 ml intradermally and 50 MBq/2 ml intraparenchymally). Ex vivo measurement of count rates was performed with a gamma probe. Comparing groups A and B in respect of registered counts per second (cps) of excised SLNs, a significant difference was found ( P<0.004). When comparisons were made between subgroups 1 and 2 (2-h elution) and between subgroups 3 and 4 (24-h elution) in respect of registered cps of excised SLNs, no significant difference was found (subgroup 1 vs 2, P=0.825; subgroup 3 vs 4, P=0.915). Use of a 2-h elution in vacuum yielded a significantly higher count rate of maximum specific activity of (99m)Tc-colloid albumin in SLNs than was achieved using a 24-h elution in vacuum. SLN procedures performed 2-3 weeks after prior excision biopsy proved reliable as compared to SLN procedures performed simultaneously with lumpectomy.
