Metastatic breast cancer (MBC) patients are almost always treated to minimize the symptom burden, and to prolong life without a curative intent. Although the prognosis of MBC patients has improved in recent years, the median survival after diagnosis is still only 3 years. Therefore, the health-related quality of life (HRQoL) should play a leading role in making treatment decisions. Heterogeneity in questionnaires used to evaluate the HRQoL in MBC patients complicates the interpretability and comparability of patient-reported outcomes (PROs) globally. In this review, we aimed to provide an overview of PRO instruments used in real-world MBC patients and to discuss important issues in measuring HRQoL. Routinely collecting symptom information using PROs could enhance treatment evaluation and shared decision-making. Standardizing these measures might help to improve the implementation of PROs, and facilitates collecting and sharing data to establish valid comparisons in research. This is a prerequisite to learn about how they could impact the clinical care pathway. In addition, the prognostic value of intensified PRO collection throughout therapy on survival and disease progression is promising. Future perspectives in the field of PROs and MBC are described.

BACKGROUND: Venous thromboembolism (VTE) is a serious complication of cancer and its treatment. The current study assessed the risk and clinical predictors of VTE in breast cancer patients by time since diagnosis.METHODS: This Swedish population–based study included 8338 breast cancer patients diagnosed from 2001 to 2008 in the Stockholm‐Gotland region with complete follow‐up until 2012. Their incidence of VTE was compared with the incidence among 39,013 age‐matched reference individuals from the general population. Cox and flexible parametric models were used to examine associations with patient, tumor, and treatment characteristics, accounting for time‐dependent effects.RESULTS: Over a median follow‐up of 7.2 years, 426 breast cancer patients experienced a VTE event (cumulative incidence, 5.1%). The VTE incidence was 3‐fold increased (hazard ratio [HR], 3.28; 95% confidence interval [CI], 2.87‐3.74) in comparison with the incidence in the general population and was highest 6 months after diagnosis (HR, 8.62; 95% CI, 6.56‐11.33) with a sustained increase in risk thereafter (HR at 5 years, 2.19; 95% CI, 1.80‐2.67). Independent predictors of VTE included the following: older age, being overweight, preexisting VTE, comorbid disease, tumor size > 40 mm, progesterone receptor (PR)–negative status, more than 4 affected lymph nodes, and receipt of chemo‐ and endocrine therapy. The impact of chemotherapy was limited to early‐onset VTE, whereas comorbid disease and PR‐negative status were more strongly associated with late‐onset events.CONCLUSIONS: This study confirms the long‐term risk of VTE in breast cancer patients and identifies a comprehensive set of clinical risk predictors. Temporal associations with patient, tumor, and treatment characteristics provide insight into the time‐dependent etiology of VTE. Cancer 2017;123:468–475. © 2016 American Cancer Society.

Lung carcinoids are neuroendocrine tumors, categorized as typical or atypical carcinoids based on their histological appearance. While most of these tumors are slow-growing neoplasms, they still possess malignant potential. Many patients are diagnosed incidentally on chest X-rays or CT scans. Presenting symptoms include cough, hemoptysis, wheezing, dyspnea, and recurrent pneumonia. Endocrine symptoms, such as carcinoid syndrome or ectopic Cushing’s syndrome, are rare. Surgery is the primary treatment and should be considered in all patients with localized disease, even when thoracic lymph node metastases are present. Patients with distant metastases may be treated with somatostatin analogues, chemotherapy, preferably temozolomide-based, mTOR inhibitors, or peptide receptor radionuclide therapy (PRRT) with 177Lu-DOTATATE. Most patients have an excellent prognosis. Poor prognostic factors include atypical histology and lymph node metastases at diagnosis. Long-term follow-up is mandatory since metastases may occur late.

Adjuvant trastuzumab is a standard of care in the treatment of Human Epidermal growth factor Receptor 2 (HER2) positive early breast cancer (eBC). Initially trastuzumab could only be administered intravenously (IV), however since 2013, a subcutaneous (SC) formulation with comparable efficacy and safety profile is available and preferred by patients. Trastuzumab SC does not require pharmacy preparation and has shorter administration time. The objective of this study was to estimate the economic efficiency of the SC formulation of trastuzumab by assessing the economic benefits of actual SC-driven process changes at one single Swedish healthcare institution. This study analyzes changes in trastuzumab administration practice after the SC formulation was introduced at the Karolinska University Hospital. Process changes were identified and introduced in order to capitalize on the inherent work efficiency benefits of the SC formulation. Actual hospital data for 2015 were used to quantitatively estimate the annual economic impact of the changes. It encompassed administrative (i.e. non-medical) data of 178 newly diagnosed HER2-positive eBC patients and a total of 2,769 SC administrations. Realized economic benefits were expressed in hours saved by nurses, direct monetary cost savings and potential infusion fee revenue that could be earned through infrastructural revenue gains. In 2015, the replacement of IV infusion to SC administration generated total time savings of more than 1,100 hours, and led to direct monetary cost savings of 603,000 EUR. It unlocked a capacity gain of 1–2 additional administrations daily within the existing facility infrastructure. Given the current remuneration structure per administration, this revenue gain translated into an incremental revenue potential of up to 3 million EUR. Data from this study showed that the shift from trastuzumab IV to SC formulation resulted in significant economic effects in terms of departmental resources related to time, direct monetary cost savings, and infrastructural revenue gains.
