Predicting postoperative complications and their impact on quality of life and functional status in older patients with breast cancer.

BACKGROUND: The percentage of older patients undergoing surgery for early-stage breast cancer has decreased over the past decade. This study aimed to develop a prediction model for postoperative complications to better inform patients about the benefits and risks of surgery, and to investigate the association between complications and functional status and quality of life (QoL). METHODS: Women aged at least 70 years who underwent surgery for Tis-3 N0 breast cancer were included between 2013 and 2018. The primary outcome was any postoperative complication within 30 days after surgery. Secondary outcomes included functional status and QoL during the first year after surgery, as assessed by the Groningen Activity Restriction Scale and the European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-BR23 questionnaires. A prediction model was developed using multivariable logistic regression and validated externally using data from the British Bridging the Age Gap Study. Linear mixed models were used to assess QoL and functional status over time. RESULTS: The development and validation cohorts included 547 and 2727 women respectively. The prediction model consisted of five predictors (age, polypharmacy, BMI, and type of breast and axillary surgery) and performed well in internal (area under curve (AUC) 0.76, 95 per cent c.i. 0.72 to 0.80) and external (AUC 0.70, 0.68 to 0.72) validations. Functional status and QoL were not affected by postoperative complication after adjustment for confounders. CONCLUSION: This validated prediction model can be used to counsel older patients with breast cancer about the postoperative phase. Postoperative complications did not affect functional status nor QoL within the first year after surgery even after adjustment for predefined confounders.

Surgery remains the standard of care for the majority of older patients with breast cancer. The percentage of older patients with breast cancer receiving surgery is decreasing. The reason for this decline is unknown, but it might be due to fear of complications. To better inform patients about the benefits and risks of surgery, the aim of this study was to develop a prediction model for complications after surgery. Another important aspect, especially for older adults with breast cancer, is quality of life, functional capacity, and ability to carry out daily tasks (functional status) after therapy. This study showed that quality of life and functional status did not decline after breast surgery, irrespective of the occurrence of postoperative complications.

Contralateral breast cancer risk in relation to tumor morphology and age-in which patients is preoperative MRI justified?

Identification of patients who are at increased risk for contralateral breast cancer is essential to determine which patients should be routinely screened for contralateral breast cancer using MRI. The aim of this study was to assess the association of age and tumor morphology with contralateral breast cancer incidence in a large, nationwide population-based study in the Netherlands. All patients with breast cancer stage I-III, diagnosed between 1989 and 2009, were selected from the Netherlands Cancer Registry. The association between contralateral breast cancer risk with tumor morphology and age was assessed using competing-risk regression according to Fine & Gray. Overall, 194,898 patients were included. In multivariable analyses, lobular tumors were significantly associated with an increased risk of contralateral breast cancer within 6 months (cumulative incidence 1.9 %, subdistribution hazard ratio (SHR) 1.17, 95 % confidence interval (CI) 1.06-1.30 compared with 1.3 % in ductal tumors, p = 0.002). Age was also associated with an increased risk of contralateral breast cancer within 6 months (SHR 2.34, 95 % CI 2.08-2.62, p < 0.002 for patients over the age of 75 as compared to patients younger than 50 years). The absolute risk of contralateral breast cancer within 6 months is only slightly increased in patients with a lobular tumor and older patients. In our view, this small increased risk does not justify standard use of preoperative MRI based on tumor morphology or age alone. We propose a more personalized strategy in which additional risk factors (family history, prognosis of primary tumor, and others) may play a role.

Colonic diverticulitis: a prospective analysis of diagnostic accuracy and clinical decision-making.

OBJECTIVE: To evaluate the diagnostic accuracy of clinical evaluation and cross-sectional imaging modalities such as ultrasound and computed tomography for patients with suspected colonic diverticulitis and to determine the value of these examinations in clinical decision-making. METHOD: A prospective analysis was conducted of 802 consecutive patients that presented with abdominal pain at the emergency department. Initial clinical diagnoses and management proposals were compared to the final diagnoses and therapeutic strategies for all patients. RESULTS: Fifty-seven patients were identified with colonic diverticulitis as the final diagnosis. The positive and negative predictive values for the clinical diagnosis of colonic diverticulitis were 0.65 and 0.98 respectively. Additional cross-sectional imaging had a positive and negative predictive value of respectively 0.95 and 0.99 or higher. These additional examinations led to a correct change of the initial clinical diagnosis in 37% of the patients, and a change in management in only 7%. CONCLUSION: The accuracy of the clinical diagnosis for colonic diverticulitis is low. Ultrasound and computed tomography have superior diagnostic accuracy but these examinations rarely change the initial management proposal.

Supracondylar fractures of the humerus in children. Comparison of results in two treatment periods.

Displaced supracondylar fractures of the humerus in children may be managed with or without Kirschner-wire fixation. The results of treatment of displaced supracondylar fractures of the humerus in children were analyzed, comparing the period before and after an audit of our results in 1997. From 1998 onward a more active policy regarding the use of percutaneous Kirschner-wire fixation was adopted. We treated 33 children between 1991 and 1997 (Period 1) and 49 children between 1998 and 2004 (Period 2). In Period 1, closed reduction and plaster immobilisation was performed in 29 patients. Four received initial Kirschner-wire fixation with plaster immobilisation. Secondary dislocation necessitating re-reduction occurred in 14 patients. In Period 2 initial Kirschner-wire fixation was performed in 41 patients, of whom 23 had open reduction. The other eight had conservative treatment consisting of closed reduction and plaster immobilization, two of them needing re-reduction. This evaluation indicates that a more active policy with regard to (open) reduction with Kirschner-wire fixation in displaced supracondylar humeral fractures in children, results in less need for secondary intervention with comparable functional and cosmetic outcome.

Primary retroperitoneal mucinous cystadenoma with sarcoma-like mural nodule : a case report and review of the literature.

Primary retroperitoneal cystadenomas are extremely rare. This is the first report in literature to describe a primary retroperitoneal cystadenoma with a sarcoma-like mural nodule. A 45-year-old woman complained of a left-sided abdominal mass. A computed tomography scan revealed a cystic mass with a mural nodule, which seemed to originate from the tail of the pancreas. At laparotomy the cyst was not adhered to the pancreas but localized retroperitoneally. Histologic examination showed a mucinous cystadenoma with only foci of borderline malignancy with a mural "sarcoma-like" nodule. In view of the surgical and histopathological findings, the mucinous cystadenoma was regarded as primary retroperitoneal. This case demonstrates that in the era of radiological preoperative refinement, pathological diagnosis remains of utmost importance, especially for rare cases.
